     B    The Credit Parties, the Lenders, the Administrative Agent, the

     (a)  Each Credit Party is a duly and validly existing corporation,
and is in good standing under the laws of the jurisdiction of its incorporation.
The execution, delivery and performance of the Credit Documents are within each
Credit Party's corporate authority and have been duly authorized by proper
corporate proceedings. This Agreement has been, and each of the other Credit
Documents required to be executed and delivered by a Credit Party will be, duly
executed and delivered by each Credit Party that is a party thereto.

Material Adverse Effect.

1.2.      FINANCIAL STATEMENTS.

     (a)  The consolidated balance sheet of the Company and its Consolidated
Subsidiaries as of December 31, 1997, and the related consolidated statements of
income, stockholders' equity and cash flow (including the notes thereto) for the
fiscal year ended on such date, reported upon by Coopers & Lybrand, present

Company and its Consolidated Subsidiaries as of said date and the consolidated
results of their operations for such fiscal year, in conformity with GAAP.

     (b)  The consolidated balance sheets of the Company and its Consolidated
Subsidiaries as of June 30, 1998, and the related consolidated statements of
income and cash flows for the quarterly period ended on such date, present
fairly in all material respects the consolidated financial position of the
Company and its Consolidated Subsidiaries as of said date and the consolidated
results of their operations for such quarterly period, in conformity with GAAP;
provided, however, that such financial statements are subject to year-end
adjustments and are presented without footnotes.

incorrect or misleading in any material respect.

of Law applicable to the Credit Parties, specifically including the certificate
of incorporation or the by-laws of a Credit Party, or any agreement or
instrument to which a Credit Party is a party, or by which it or its properties
is bound, or constitute a default thereunder, except where such conflict, breach
or default would not reasonably be expected to have a Material Adverse Effect or
(ii) result in or require the creation of any Lien (other than those
contemplated in or created in connection with the Credit Documents) upon a
Credit Party or with respect to its properties.

                                       2

<PAGE>   20

similar act by or in respect of, any Governmental Authority or any other Person
is required to be obtained or made by or on behalf of any Credit Party in
connection with the borrowings or other extensions of credit hereunder or with
the execution, delivery, performance, validity or enforceability of the Credit
Documents to which such Credit Party is a party, except for (i) consents,
authorizations, notices and filings described in Schedule III, all of which have
been obtained or made or have the status described in such Schedule III and (ii)
filings to perfect the Liens created by the Collateral Documents.

1.4.      NO EVENTS OF DEFAULT.

     No Event of Default specified in subsection 6.1 of this Agreement and no
event of default specified in any other agreement evidencing indebtedness of the
Company or any of its Subsidiaries for borrowed money in excess of $25,000,000,
and no event which, with the giving of notice or lapse of time, or both, could
become such an Event of Default or event of default, has occurred and is
continuing.

1.5.      LITIGATION.

     Except as set forth on the Company's Form 10-Q filed with the Securities
and Exchange Commission for the quarterly period ended June 30, 1998, there are
no actions, suits or proceedings pending or, to the knowledge of a Credit Party,
threatened against or affecting the Company or any Consolidated Subsidiary
before any court or before any governmental or administrative body or agency,
which could reasonably be expected to have a Material Adverse Effect.

1.6.      USE OF PROCEEDS.

     The proceeds of the Revolving Credit Loans shall be used for general
working capital purposes in the ordinary course of business consistent with past
practices of the Company. The Letters of Credit shall be used only for or in
connection with appeal bonds, reimbursement obligations arising in connection
with surety and reclamation bonds, reinsurance, domestic or international trade
transactions and obligations not otherwise aforementioned relating to
transactions entered into by the applicable account party in the ordinary course
of business. For purposes hereof "general working capital purposes" shall
include capital expenditures but shall not include (i) the funding of
acquisitions or (ii) the payment, prepayment, purchase or redemption of
Indebtedness (other than (a) payments or prepayments of Indebtedness evidenced
by this Agreement and the Notes, (b) regularly scheduled payments of
Indebtedness permitted under subsection 5.2(f), including any payment or
prepayment of the Bridge Notes with the proceeds of a refinancing thereof that
is permitted under subsection 5.2(f)(ix) and (c) the prepayment or payment of
the outstanding principal amount of the Floating Rate Preferred Securities due
December 29, 2000 referenced on Schedule VIII in an aggregate amount equal to
$170,000,000) or of any Capital Stock. The proceeds of the Tranche D Term Loan
shall be used to make the repayments required by subsection 2.6(d), and any such
proceeds thereafter remaining shall be used to pay fees and expenses that are
due under the Credit Documents or payable by the Company in connection with the
issuance and sale of the Senior Notes or the Bridge Notes.

1.7.      NO CHANGE.

     Since June 30, 1998, there has been no development or event which has had
or could reasonably be expected to have a Material Adverse Effect.

1.8.      FEDERAL REGULATIONS.

     No part of the Letters of Credit or 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 of the Board of
Governors of the Federal Reserve System as now and from time to time hereafter
in effect or for any purpose which violates the provisions of the Regulations of
such Board of Governors. If requested by any Lender or the Administrative Agent,
each Borrower will furnish to the

                                       3

<PAGE>   21

Administrative Agent and each Lender a statement to the foregoing effect in
conformity with the requirements of FR Form U-1 referred to in said
Regulation U.

1.9.      ERISA.

     Each of the following statements is true, except to the extent that the
events or conditions causing such statements to be untrue, either individually
or in the aggregate, would not be reasonably likely to result in any liability
having a Material Adverse Effect: 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 during the five-year period prior to the date on
which this representation is made or deemed made with respect to any 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, during such five-year
period. 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. Neither a Credit Party nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither a Credit Party nor any Commonly Controlled Entity would become subject
to any liability under ERISA if such Credit Party 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.

1.10.     INVESTMENT COMPANY ACT; OTHER REGULATIONS.

     No Credit Party is an "investment company", or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended. No Credit Party is subject to regulation under any Federal or State
statute or regulation which limits its ability to incur Indebtedness. No
director, executive officer or principal shareholder of a Credit Party or any of
its Subsidiaries is a director, executive officer or principal shareholder of
any Lender. For the purposes hereof the terms "director", "executive officer"
and "principal shareholder" (when used with reference to any Lender) have the
respective meanings assigned thereto in Regulation O issued by the Board of
Governors of the Federal Reserve System. None of the transactions contemplated
by this Agreement (including, without limitation, the direct or indirect use of
the proceeds of the Loans) will violate or result in a violation of the
Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as
amended, or regulations issued pursuant thereto.

1.11.     COMPLIANCE WITH LAW.

     Each of the Company and its Consolidated Subsidiaries 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.

1.12.     TAXES.

     Each of the Company and its Consolidated Subsidiaries has filed, or caused
to be filed, all tax returns (federal, state, provincial, local and foreign)
required to be filed and paid (a) all amounts of taxes shown thereon to be due
(including interest and penalties) and (b) all other taxes, fees, assessments
and other governmental charges (including mortgage recording taxes, documentary
stamp taxes and intangibles taxes) owing by it, except for such taxes (i) which
are not yet delinquent or (ii) that are being contested in good faith and by
proper proceedings, and against which adequate reserves are being maintained in
accordance with GAAP (if such reserves are required pursuant to GAAP). No Credit
Party is aware as of the Closing Date or as of the Third Amendment Effective
Date of any proposed tax assessments against any of the Company and its
Consolidated Subsidiaries, which could reasonably be expected to have a Material
Adverse Effect and against which adequate reserves are not being maintained in
accordance with GAAP (if such reserves are required pursuant to GAAP).

1.13.     SUBSIDIARIES.

     Set forth on Schedule II is a complete and accurate list of all
Subsidiaries of the Company. Information on Schedule II includes, for each
Credit Party and each other Material Subsidiary or First Tier Foreign
Subsidiary, jurisdiction of incorporation, the number of shares of each class of
Capital Stock outstanding, the number and percentage of outstanding shares of
each class owned (directly or indirectly) by a Credit Party; and the number and
effect, if exercised, of all outstanding options, warrants, rights of conversion
or purchase and all other similar rights with respect thereto. The outstanding
Capital Stock of all such Subsidiaries is validly issued, fully paid and
non-assessable and is owned by each such Credit Party, directly or indirectly,
free and clear of all Liens (other than those arising under or contemplated in
connection with the Credit Documents). Other than as set forth in Schedule II,
no such Subsidiary has outstanding any securities convertible into or
exchangeable for its Capital Stock nor does any such Person have outstanding any
rights to subscribe for or to purchase or any options for the purchase of, or
any agreements providing for the issuance (contingent or otherwise) of, or any
calls, commitments or claims of any character relating to its Capital Stock.
Schedule II may be updated from time to time by the Company by giving written
notice thereof to the Administrative Agent.

1.14.     ENVIRONMENTAL MATTERS.

          (a)  Except as would not have or be reasonably expected to have a
Material Adverse Effect:

               (i) Each of the real properties owned by the Credit Parties (the
          "Real Properties") and all operations at the Real Properties are in
          compliance with all applicable Environmental Laws, and there is no
          violation of any Environmental Law with respect to the Real Properties
          or the businesses operated by the Company or any of its Subsidiaries
          (the "Businesses"), and there are no conditions relating to the
          Businesses or Real Properties that would be reasonably expected to
          give rise to liability under any applicable Environmental Laws.

               (ii) No Credit Party has received any written notice of, or
          inquiry from any Governmental Authority regarding, any violation,
          alleged violation, non-compliance, liability or potential liability
          regarding Hazardous Materials or compliance with Environmental Laws
          with regard to any of the Real Properties or the Businesses, nor does
          any Credit Party have knowledge or reason to believe that any such
          notice is being threatened.

               (iii) Hazardous Materials have not been transported or disposed
          of from the Real Properties, or generated, treated, stored or disposed
          of at, on or under any of the Real Properties or any other location,
          in each case by, or on behalf or with the permission of, the Company
          or any of its Subsidiaries.

               (iv) No judicial proceeding or governmental or administrative
          action is pending or, to the knowledge of any Credit Party,
          threatened, under any Environmental Law to which any Credit Party is
          or, to the best knowledge of such Credit Party, will be named as a
          party, 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 Company or any of its Subsidiaries, the Real Properties
          or the Businesses.

               (v) There has been no release or, to the best knowledge of any
          Credit Party, threat of release of Hazardous Materials at or from the
          Real Properties, or arising from or related to the operations
          (including, without limitation, disposal) of the Company or any of its
          Subsidiaries in connection with the Real Properties or otherwise in
          connection with the Businesses, in violation of, or in amounts or in a
          manner that could give rise to liability under, Environmental Laws.

                                       5

<PAGE>   23

               (vi) None of the Real Properties contains, or has previously
          contained, any Hazardous Materials at, on or under the Real Properties
          in amounts or concentrations that, if released, constitute or
          constituted a violation of, or would give rise to liability under,
          Environmental Laws.

               (vii) No Credit Party, nor any of its Subsidiaries, has assumed
          any liability of any Person (other than another Credit Party, or one
          of its Subsidiaries) under any Environmental Law.

     (b)  The Company has adopted procedures that are designed to (i) ensure
that each Credit Party, each of its operations and each of the properties owned
or leased by each Credit Party remains in compliance with applicable
Environmental Laws, to the extent that the failure to comply with such
Environmental Laws would have or would be reasonably expected to have a Material
Adverse Effect, and (ii) manage, to the same extent as and in accordance with
the practices of companies engaged in the same or a similar business, any
liabilities or potential liabilities that each Credit Party, any of its
operations and each of the properties owned or leased by each Credit Party may
have under applicable Environmental Laws.

1.15.     SOLVENCY.

     Each Credit Party is Solvent.

1.16.     DISCLOSURE.

     Neither this Agreement nor any financial statements delivered to the
Lenders nor any other document, certificate or statement furnished to the
Lenders by or on behalf of the Company or any of its Consolidated Subsidiaries
in connection with the transactions contemplated hereby contains any untrue
statement of a material fact or omits to state a material fact necessary in
order to make the statements contained therein or herein not misleading.

1.17.     NO BURDENSOME RESTRICTIONS.

     Neither the Company nor any of its Subsidiaries is a party to any agreement
or instrument or subject to any other obligation or any charter or corporate
restriction or any provision of any applicable law, rule or regulation which,
individually or in the aggregate, could have a Material Adverse Effect.

1.18.     REPRESENTATIONS AND WARRANTIES FROM MERGER AGREEMENT.

     As of the Closing Date, each of the representations and warranties made in
the Merger Agreement by each of the parties thereto is true and correct in all
material respects.

1.19.     YEAR 2000 COMPLIANCE.

     Each of the Credit Parties has (i) initiated a review and assessment of all
areas within its and each of its Subsidiaries' businesses and operations
(including those affected by suppliers, vendors and customers) that could be
adversely affected by the "Year 2000 Problem" (that is, the risk that computer
applications may not be able to recognize and properly perform date-sensitive
functions after December 31, 1999), (ii) developed a plan and timeline for
addressing the Year 2000 Problem on a timely basis, and (iii) to date,
implemented that plan in accordance with that timetable. Based on the foregoing,
each Credit Party believes that all computer applications that are material to
its or any of its Subsidiaries' business and operations are reasonably expected
on a timely basis to be able to perform properly date-sensitive functions for
all dates before and after January 1, 2000 (that is, be "Year 2000 Compliant"),
except to the extent that a failure to do so could not reasonably be expected to
have a Material Adverse Effect.

1.20.     COLLATERAL DOCUMENTS.

     The Collateral Documents create valid security interests in, and Liens on,
the Collateral purported to be covered thereby, which security interests and
Liens will upon the filing of the UCC financing statements executed by the
Credit Parties in the appropriate filing jurisdictions, the delivery of all
stock certificates pledged pursuant to the Pledge Agreement and the recording of
the Mortgages in the appropriate filing jurisdictions, be and remain perfected
security interests and Liens, prior to all other Liens other than Liens
permitted under subsection 5.2(a). Each of the representations and warranties
made by the Company and the other Credit Parties in the Collateral Documents is
true and correct in all material respects.

          Amounts (on a pro rata basis), until all Revolving Committed Amounts
          are reduced to zero, and then ratably to each Tranche of outstanding
          Term Loans (credited pro rata across amortization payment maturities
          in such Tranche).

     Within the parameters of the applications set forth above, each mandatory
prepayment required by this subsection 2.6(b) shall be applied first to Base
Rate Loans and then to Eurodollar Loans in direct order of Interest Period
maturities. Each such mandatory prepayment shall be subject to subsections
2.6(e) and 3.5 and shall be accompanied by interest on the principal amount
prepaid through the date of prepayment.

     (c)  Mandatory Payments on Restatement Effective Date. On the
Restatement Effective Date, the Borrowers shall repay (i) all Revolving Credit
Loans outstanding under the Existing Credit Agreement and (ii) all obligations
outstanding under that certain C$220,000,000 Promissory Note dated January 19,
1999 executed by the Canadian Borrower in favor of Bank of America Canada. It is
understood that such repayments may be made with the proceeds of borrowings
funded under this Agreement on the Restatement Effective Date in accordance with
the borrowing procedures set forth in subsection 2.3 hereof.

     (d)  Mandatory Payments on Third Amendment Effective Date. On the Third
Amendment Effective Date, the Company shall prepay, with the interest accrued
and unpaid thereon, $126,000,000 of the principal of the Tranche A Term Loan and
$256,000,000 of the principal of the Revolving Credit Loans from the proceeds of
(i) borrowings funded under the Tranche D Term Loan on the Third Amendment
Effective Date in accordance with the borrowing procedures set forth in
subsection 2.17(b) hereof and (ii) the issuance of the Senior Notes. Such
prepayment of the Tranche A Term Loan shall be credited in direct order of
maturity toward the December 31, 2000, March 31, 2001 and June 30, 2001
amortization payment maturities that were required under subsection 2.17(d)(i)
prior to giving effect to the Third Amendment. Such prepayment of the Revolving
Credit Loans shall be allocated to the U.S.

                                       14

<PAGE>   32

Revolving Loans, the Multicurrency Revolving Loans or the Canadian Revolving
Loans as the Company may direct and shall not reduce any of the Revolving
Committed Amounts.

     (e)  Tranche D Refusal Option. Notwithstanding anything to the contrary in
this subsection 2.6, in the case of each mandatory prepayment described in
subsection 2.6(b) that is to be allocated to the Tranche D Term Loan at any time
when the Tranche A Term Loan remains outstanding, the Borrower making such
prepayment shall give the Administrative Agent telephonic notice (promptly
confirmed in writing) at least five Business Days prior to the date of such
prepayment, requesting that the Administrative Agent prepare and provide to each
Lender holding any of the Tranche D Term Loan a notice (in form and substance
reasonably satisfactory to the Administrative Agent) to the effect that such
Lender has the right, at its option, to accept or decline its share of such
prepayment or to accept a portion thereof and decline the remainder, so long as
the amount declined does not exceed the amount of the Tranche A Term Loan that
will remain outstanding after giving effect to the portion of such prepayment
otherwise allocable to the Tranche A Term Loan (including, on a ratable basis,
any portion so declined by other Lenders holding any of the Tranche D Term Loan)
and setting forth procedures reasonably satisfactory to the Administrative Agent
relating to the exercise of such option. The Administrative Agent thereupon
shall promptly prepare and deliver such notice to such Lenders. Each such Lender
shall be deemed to have elected to accept or decline its share of such
prepayment as determined by the Administrative Agent pursuant to the procedures
set forth in the notice. The amount so declined by such Lenders shall be
applied, on the date the prepayment is made, as an additional mandatory
prepayment of the Tranche A Term Loan.

     (f)  Pro Rata Reductions of the Prudential Obligations. With respect to
the application of proceeds pursuant to subsections 2.6(b)(v)(H) and (I) above,
(i) the percentage of such proceeds allocated to the specified Bank Obligations
shall correspond to a fraction, the numerator of which shall be the amount of
all Bank Obligations outstanding at the time of such application and the
denominator of which shall be the sum of all Bank Obligations and all Prudential
Obligations outstanding at the time of such application, and (ii) the percentage
of such proceeds allocated to the Prudential Obligations shall correspond to a
fraction, the numerator of which shall be the amount of all Prudential
Obligations outstanding at the time of such application and the denominator of
which shall be the sum of all Bank Obligations and all Prudential Obligations
outstanding at the time of such application; provided, however, that each of the
holders of the Prudential Obligations shall have the right, at its option, to
accept or decline its share of such prepayment specified in subsection 2.6(b) or
to accept a portion thereof and decline the remainder (including, on a ratable
basis, any portion so declined by other holders of the Prudential Obligations).
The amount so declined by such holders of the Prudential Obligations shall be
applied, on the date the prepayment is made, as an additional mandatory
prepayment of the Bank Obligations in the amounts so specified in the applicable
clause of subsection 2.6(b).

     (g)  Amendments to Subsection 2.6(b). Without limiting the requirements
set forth in subsection 9.1, neither (i) the time for or the amount or the
manner of application of proceeds of any mandatory prepayment required by
subsection 2.6(b)(ii), (iii), (iv) or (v) hereof nor (ii) any provision
providing for the allocation of any payments between the Term Loan Tranches
shall be amended without the consent of (x) Lenders holding in the aggregate
more than 50% of the outstanding Tranche D Term Loans and (y) Lenders holding in
the aggregate more than 50% of the outstanding Tranche A Term Loans and the
Revolving Committed Amount.

2.7.     CONVERSION AND CONTINUATION OPTIONS.

     (a)  A Borrower may elect from time to time to convert Eurodollar Loans
denominated in U.S. Dollars to Base Rate Loans denominated in U.S. Dollars by
the Company (on behalf of a Borrower other than the Canadian Borrower) or the
Canadian Borrower, as applicable, giving the applicable Agent at least three
Business Days' prior irrevocable notice of such election on behalf of the
respective

                                       15

<PAGE>   33

Borrower, provided that any such conversion of Eurodollar Loans may only be made
on the last day of an Interest Period with respect thereto. A Borrower may elect
from time to time to convert Revolving Credit Loans or Term Loans that are Base
Rate Loans denominated in U.S. Dollars to Eurodollar Loans denominated in U.S.
Dollars by the Company (on behalf of a Borrower other than the Canadian
Borrower) or the Canadian Borrower, as applicable, giving the applicable Agent
at least three Business Days' prior irrevocable notice of such election on
behalf of the respective Borrower. Any such notice of conversion to Eurodollar
Loans shall specify the length of the initial Interest Period or Interest
Periods therefor. Upon receipt of any such notice the applicable Agent shall
promptly notify each applicable Lender thereof. All or any part of outstanding
Eurodollar Loans and Base Rate Loans may be converted as provided herein,
provided that (i) no Base Rate Loan may be converted into a Eurodollar Loan when
any Event of Default has occurred and is continuing, (ii) no Base Rate Loan may
be converted into a Eurodollar Loan of any Tranche after the date that is one
month prior to the Termination Date for such Tranche and (iii) no Loan may be
converted to a Loan in a different currency.

     (b) Any Eurodollar Loan may be continued as a Eurodollar Loan in the same
currency upon the expiration of the then current Interest Period with respect
thereto by the Company (on behalf of a Borrower other than the Canadian
Borrower) or the Canadian Borrower, as applicable, giving notice to the
applicable Agent on behalf of the respective Borrower, in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 7, of
the length of the next Interest Period to be applicable to such Loans, provided
that no Eurodollar Loan may be continued as such (i) when any Event of Default
has occurred and is continuing or (ii) after the date that is one month prior to
the Termination Date for the relevant Tranche and provided, further, that if the
Company (on behalf of a Borrower other than the Canadian Borrower) or the
Canadian Borrower, as applicable, 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, (A) such Loans denominated in U.S. Dollars
shall be automatically converted to Base Rate Loans bearing interest based upon
the ABR or the BACAN U.S. Base Rate, as applicable, and (B) such Loans
denominated in Euros shall be automatically continued for a like Interest
Period, in each case on the last day of such then expiring Interest Period,
except that if such last day of such then expiring Interest Period is within one
month of the Termination Date of the relevant Tranche, then any such Loans
denominated in Euros shall be automatically redenominated in U.S. Dollars and
converted to ABR Loans.

     (c) The Canadian Borrower shall have the option, on any Business Day, to
convert a Canadian Base Rate Revolving Loan denominated in Canadian Dollars into
a Bankers' Acceptance, to continue a maturing Bankers' Acceptance in accordance
with subsection 2.18 or to convert a maturing Bankers' Acceptance into a
Canadian Base Rate Revolving Loan denominated in Canadian Dollars; provided,
however, (i) each such continuation or conversion must be requested by the
Canadian Borrower pursuant to an irrevocable notice to the Canadian
Administrative Agent, substantially in the form of Exhibit F, in compliance with
the terms set forth below, (ii) the Canadian Borrower must comply with all the
requirements of subsection 2.18, and (iii) failure by the Canadian Borrower to
properly continue a Bankers' Acceptance shall be deemed a conversion to a Base
Rate Loan. Each continuation or conversion must be requested by the Canadian
Borrower no later than 11:00 A.M., Toronto, Ontario time, (A) two Business Days
prior to the date of a requested conversion of a Bankers' Acceptance to a Base
Rate Loan or (B) two Business Days prior to the date of a requested continuation
of a Bankers' Acceptance or conversion of a Base Rate Loan to a Bankers'
Acceptance, in each case pursuant to an irrevocable notice submitted to the
Canadian Administrative Agent which shall set forth (x) that the Loans to be
continued or converted are Canadian Revolving Loans, (y) whether the Canadian
Borrower wishes to continue or convert such Loans and (z) if the request is to
continue a Bankers' Acceptance or convert a Base Rate Loan to a Bankers'
Acceptance, the maturity date applicable thereto. The Canadian Administrative
Agent shall give each Canadian Lender notice as promptly as practicable of any
such proposed continuation or conversion pursuant to this section.

                                       16

2.8.     MINIMUM AMOUNTS OF TRANCHES AND MAXIMUM NUMBER OF EURODOLLAR LOANS.

     All borrowings, conversions and continuations of Eurodollar Loans hereunder
and all selections of Interest 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 Eurodollar Loans comprising each Eurodollar
Tranche shall be equal to a multiple of $1,000,000 or 1,000,000 Euros, as
applicable, in excess of an amount of the applicable currency having a Dollar
Amount of $5,000,000. Notwithstanding anything in this Agreement to the
contrary, (a) no more than five (5) Eurodollar Loans shall be outstanding under
the Canadian Revolving Committed Amount at any time and (b) no more than ten
(10) Eurodollar Loans shall be outstanding under the other Revolving Committed
Amounts and the Term Loan Tranches, collectively, at any time (it being
understood that, for purposes hereof, Eurodollar Loans with different Interest
Periods shall be considered as separate Eurodollar Loans, even if they begin on
the same date, although borrowings, continuations and conversions may, in
accordance with the provisions hereof, be combined at the end of existing
Interest Periods to constitute a new Eurodollar Loan with a single Interest
Period).

2.9.     INTEREST RATES AND PAYMENT DATES.

     (a)  Each Revolving Eurodollar Loan shall bear interest for each
Interest Period with respect thereto at a rate per annum equal to the Eurodollar
Rate determined for such Interest Period plus the Applicable Margin for
Revolving Eurodollar Loans and Bankers' Acceptances, payable in the same
currency in which the principal amount of such Loan was denominated during the
relevant Interest Period.

     (b)  Each Term Eurodollar Loan of any Tranche shall bear interest for
each Interest Period with respect thereto at a rate per annum equal to the
Eurodollar Rate determined for such Interest Period plus the Applicable Margin
for Term Eurodollar Loans of such Tranche, payable in the same currency in which
the principal amount of such Loan was denominated during the relevant Interest
Period.

     (c)  Each ABR Loan of any Tranche shall bear interest at a rate per
annum equal to the ABR plus the Applicable Margin for Base Rate Loans of such
Tranche.

     (d)  Each Canadian Base Rate Revolving Loan made in Canadian Dollars
shall accrue interest at the Canadian Prime Rate plus the Applicable Margin for
Base Rate Loans, payable in Canadian Dollars. Each Canadian Base Rate Revolving
Loan made in U.S. Dollars shall accrue interest at the BACAN U.S. Base Rate plus
the Applicable Margin for Base Rate Loans, payable in U.S. Dollars.

     (e)  If all or a portion of (i) the principal amount of any Loan, (ii)
any interest payable thereon or (iii) any Facility 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 (y) in the case of any overdue interest, Facility Fee or
other amount, the rate described in paragraph (c) of this subsection 2.9 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).

     (f)  Interest on the Revolving Credit Loans and the Term Loans shall be
payable in arrears on each Interest Payment Date, provided that interest
accruing pursuant to paragraph (e) of this subsection 2.9 shall be payable from
time to time on demand.

     (g)  The principal amount of, and any unpaid interest on, all Loans
shall be due and payable in full (i) in the case of Revolving Credit Loans, on
the Revolving Credit Termination Date and (ii) in the case of Term Loans, on the
respective final maturity dates specified in subsection 2.17(d), in each case

                                       17

<PAGE>   35

unless accelerated sooner pursuant to subsection 6.1 or unless subject to a
mandatory prepayment required by subsection 2.6(b).

     (h)  The Swingline Loans shall bear interest, and such interest shall
be payable, as specified in subsection 2.15(c).

2.10.    COMPUTATION OF INTEREST AND FEES.

     (a)  Unless otherwise specifically provided herein, Facility Fees and
interest shall be calculated on the basis of a 360-day year for the actual days
elapsed, except with respect to computation of interest on Base Rate Loans
determined by reference to the Prime Rate (as defined in the definition of
"ABR"), the BACAN U.S. Prime Rate or the Canadian Prime Rate, which shall be
calculated based on a year of 365 or 366 days, as appropriate. The Agents shall
as soon as practicable notify the Company and the applicable Lenders of each
determination of a Eurodollar Rate. Any change in the interest rate on a Loan
resulting from a change in the ABR, BACAN U.S. Base Rate, Canadian Prime 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 Company and the Lenders of the
effective date and the amount of each such change in interest rate.

     (b) Each determination of an interest rate by an Agent pursuant to any
provision of this Agreement shall be conclusive and binding on the Credit
Parties and the Lenders in the absence of manifest error. Each Agent shall, at
the request of the Company, deliver to the Company a statement showing the
quotations used by such Agent in determining any interest rate pursuant to
subsection 2.9(a).

     (c)  For purposes of the Interest Act (Canada), if interest computed on
the basis of a 360-day year is payable for any part of a calendar year, the
equivalent yearly rate of interest may be determined by multiplying the
specified rate of interest by the number of days (365 or 366) in such calendar
year and dividing such product by 360.

2.11.    PRO RATA TREATMENT AND PAYMENTS.

     (a)  Each borrowing of Revolving Credit Loans or Term Loans by a
Borrower from the Lenders hereunder, each payment by the Company on account of
the Facility Fees and the Letter of Credit Fee hereunder and any reduction of
the Commitments of the Lenders shall be made pro rata according to the
respective Commitment Percentages of the applicable Lenders. Each payment
(including each prepayment) by a Borrower or another Credit Party on account of
principal of and interest on the Revolving Credit Loans, Term Loans or other
extensions of credit shall be made pro rata according to the respective amounts
of principal and interest then due and owing to the applicable Lenders except
(in the case of mandatory prepayments allocated to the Tranche D Term Loan) to
the extent otherwise elected by the Lenders holding the Tranche D Term Loan
pursuant to subsection 2.6(e). All payments of principal, interest and fees in
connection with the Canadian Revolving Loans shall be made by the Credit Parties
to the Canadian Administrative Agent on the date due by 11:00 A.M., Toronto,
Ontario time (in Canadian Dollars or U.S. Dollars, as applicable) in immediately
available funds, without setoff or counterclaim. All other payments (including
prepayments) to be made by a Borrower or another Credit Party hereunder and
under the Notes, whether on account of principal, interest, fees or otherwise,
shall be made without set off or counterclaim and shall be made prior to 11:00
A.M., Charlotte, North Carolina time, on the due date thereof to the
Administrative Agent, for the account of the applicable Lenders (unless such
payment is for the Administrative Agent's own account) at the Administrative
Agent's office specified in subsection 9.2, in U.S. Dollars or in Euros, as
applicable, and in immediately available funds. If applicable, each Agent shall
distribute such payments to the applicable 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,

                                       18

<PAGE>   36

interest thereon shall be payable at the 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.

     (b)  Unless the Administrative Agent or the Canadian Administrative
Agent, as applicable, 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
portion of such borrowing available to such Agent, such Agent may assume that
such Lender is making such amount available to such Agent, and such Agent may,
in reliance upon such assumption, make available to the respective Borrower a
corresponding amount. If the Administrative Agent or the Canadian Administrative
Agent, as applicable, in such circumstances, makes available to such Borrower
such corresponding amount and such Lender does not make available such ratable
portion of such borrowing to such Agent by the required time on the Borrowing
Date therefor, such Lender shall pay to such Agent, on demand, its portion of
such borrowing with interest thereon at a rate equal to the Federal Funds
Effective Rate (as defined in the definition of "ABR") for the period until such
Lender makes such amount immediately available to such Agent. A certificate of
the 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 portion of such borrowing is not made available to the applicable
Agent by such Lender within three Business Days of such Borrowing Date, such
Agent, having made available to the respective Borrower a corresponding amount,
shall also be entitled to recover such corresponding amount with interest
thereon at the rate per annum applicable to ABR Loans, on demand, from such
Borrower. Nothing contained in this subsection 2.11(b) shall relieve any Lender
which has failed to make available its portion of any borrowing hereunder from
its obligation to do so in accordance with the terms hereof.

2.12.    TAXES.

     (a) All payments made by a Credit Party under this Agreement and the Notes
shall be made free and clear of, and without deduction or withholding for or on
account of, any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter imposed,
levied, collected, withheld or assessed by any Governmental Authority, excluding
net income taxes and franchise taxes (imposed in lieu of net income taxes)
imposed on an 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 to the extent any such connection arose from such
Agent or such Lender having executed, delivered or performed its obligations or
received a payment under, or enforced, this Agreement or the Notes). 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 an Agent or any Lender hereunder or under the Notes, 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 no
Credit Party shall be required to increase any such amounts payable to any
Lender that is not organized under the laws of the United States of America or a
state thereof if such Lender fails to comply with the requirements of paragraph
(b) of this subsection. Whenever any Non-Excluded Taxes are payable by a Credit
Party, as promptly as possible thereafter such Credit Party shall send to the
Administrative Agent for its own account or for the account of such Lender, as
the case may be, a certified copy of an original official receipt received by
such Credit Party showing payment thereof. If a Credit Party fails to pay any
Non-Excluded Taxes when due to the appropriate taxing authority or fails to
remit to the Administrative Agent the required receipts or other required
documentary evidence, such Credit Party shall indemnify the Agents and the
Lenders for any incremental taxes, interest or penalties that may become payable
by

                                       19

<PAGE>   37

an 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 Notes and all other amounts payable hereunder.

     (b)  Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a "Foreign Lender") shall:

          (i) deliver to the Company and the Administrative Agent (A) two duly
     completed copies of United States Internal Revenue Service Form 1001 or
     4224, or successor applicable form, as the case may be, and (B) an Internal
     Revenue Service Form W-8 or W-9 or successor applicable form, as the case
     may be;

          (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 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;

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

          (iv) otherwise cooperate, to the extent not detrimental to its own
     interests, with the Company in reducing or eliminating withholding or
     deducting with respect to any Non-Excluded Taxes;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Company and the
Administrative Agent. Such Lender shall certify (i) in the case of a Form 4224,
that the payments it receives from the Company under this Agreement are
effectively connected with a trade or business in the United States and, in the
case of a Form 1001, that it is entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income
taxes and (ii) in the case of a Form W-8 or W-9, 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 9.6 shall, upon the
effectiveness of the related transfer, be required to provide all of the forms
and statements required pursuant to this subsection, provided that in the case
of a Participant such Participant shall furnish all such required forms and
statements to the Lender from which the related participation shall have been
purchased.

     (c)  No Credit Party shall be required to indemnify any Foreign Lender
or to pay any additional amounts to any Foreign Lender in respect of United
States Federal withholding tax pursuant to paragraph (a) above to the extent
that the obligation to withhold amounts with respect to United States Federal
withholding tax existed on the date such Foreign Lender became a party to this
Agreement and such Credit Party was on such date a party to whom the applicable
Foreign Lender was obligated to extend credit under this Agreement.

2.13.    DESIGNATED BORROWERS.

     (a)  Addition of Designated Borrowers. Subject to clause (c) below, the
Company may request designation of any of its wholly-owned Material Subsidiaries
(an "Applicant Borrower") as a Designated Borrower hereunder by delivery of such
a request to the Administrative Agent together with an executed copy of a
Borrower Joinder Agreement in substantially the form attached as Exhibit D. The
Administrative Agent will promptly notify the U.S. Lenders and the Multicurrency
Lenders of any such request together with a copy of the Borrower Joinder
Agreement executed by the Applicant Borrower.

                                       20

<PAGE>   38

The joinder of each Applicant Borrower as a Designated Borrower will be subject
to delivery of executed promissory notes, if any, required in connection
therewith, and supporting resolutions, articles of incorporation, incumbency
certificates, opinions of counsel of the type required pursuant to subsection
4.1 and such other items as the Administrative Agent and/or the Required Lenders
may reasonably request. Any such addition of a Designated Borrower shall be
effective five Business Days after receipt by the Administrative Agent of the
items required by the Administrative Agent and the Required Lenders in
connection therewith. Such Designated Borrower shall thereupon become a party
thereto and a Designated Borrower hereunder and shall be (i) entitled to all
rights and benefits of a Borrower hereunder and under each instrument executed
pursuant hereto and (ii) subject to all obligations of a Borrower hereunder and
thereunder.

     (b)  Removal of a Borrower. The Company may request that any of its
Subsidiaries which is a Borrower hereunder (other than the Canadian Borrower)
cease to be a Borrower by delivering to the Administrative Agent (which shall
promptly deliver copies thereof to each U.S. Lender and each Multicurrency
Lender) a written notice to such effect. Such Borrower shall cease to be a
Borrower hereunder on the later to occur of (i) the date the Administrative
Agent receives such request and (ii) the date such Borrower has paid all of its
Loans and all accrued and unpaid interest, fees and other obligations hereunder
or in connection herewith.

     (c) Termination of Option. From and after the Third Amendment Effective
Date, the Company no longer shall be entitled to designate new Designated
Borrowers pursuant to this subsection 2.13.

2.14.    SEVERAL LIABILITY OF BORROWERS.

     The obligations of the Borrowers, as Borrowers, are several and not joint
obligations of each of the Borrowers.

2.15.    SWINGLINE LOAN SUBFACILITY.

     (a)  Swingline Commitment. Subject to the terms and conditions hereof
and in reliance upon the representations and warranties set forth herein, the
Swingline Lender, in its individual capacity, agrees to make certain revolving
credit loans requested by the Company in U.S. Dollars to the Company (each a
"Swingline Loan" and, collectively, the "Swingline Loans") from time to time
during the Commitment Period for the purposes hereinafter set forth; provided,
however, (i) the aggregate principal amount of Swingline Loans outstanding at
any time shall not exceed FIFTY MILLION DOLLARS ($50,000,000) (the "Swingline
Committed Amount"), and (ii) the aggregate Dollar Amount with respect to
principal of outstanding U.S. Revolving Loans plus outstanding Multicurrency
Revolving Loans plus outstanding Swingline Loans plus all LOC Obligations shall
not exceed the sum of the U.S. Revolving Committed Amount plus the Multicurrency
Revolving Committed Amount. Swingline Loans hereunder shall be made as ABR Loans
in accordance with the provisions of this subsection 2.15, and may be repaid and
reborrowed in accordance with the provisions hereof.

     (b)  Swingline Loan Advances.

          (i) Notices; Disbursement. Whenever the Company desires a Swingline
     Loan advance hereunder it shall give written notice (or telephonic notice
     promptly confirmed in writing) to the Swingline Lender not later than 1:00
     P.M. (Charlotte, North Carolina time) on the Business Day of the requested
     Swingline Loan advance. Each such notice shall be irrevocable and shall
     specify (A) that a Swingline Loan advance is requested, (B) the date of the
     requested Swingline Loan advance (which shall be a Business Day) and (C)
     the principal amount of the Swingline Loan advance requested. Each
     Swingline Loan shall be made as an ABR Loan and shall have such maturity
     date as the Swingline Lender and the Company shall agree upon receipt

                                       21

<PAGE>   39

     by the Swingline Lender of any such notice from the Company. The Swingline
     Lender shall initiate the transfer of funds representing the Swingline Loan
     advance to the Company by 3:00 P.M. (Charlotte, North Carolina time) on the
     Business Day of the requested borrowing.

          (ii) Minimum Amounts. Each Swingline Loan advance shall be in a
     minimum principal amount of $1,000,000 and in integral multiples of
     $500,000 in excess thereof (or the remaining amount of the Swingline
     Committed Amount, if less).

          (iii) Repayment of Swingline Loans. The principal amount of all
     Swingline Loans shall be due and payable on the earlier of (A) the maturity
     date agreed to by the Swingline Lender and the Company with respect to such
     Loan (which maturity date shall not be a date more than twenty-eight (28)
     Business Days from the date of advance thereof) or (B) the Revolving Credit
     Termination Date. The Swingline Lender may, at any time, in its sole
     discretion, by written notice to the Company, the U.S. Lenders and the
     Multicurrency Lenders, demand repayment of its Swingline Loans advanced in
     accordance with the terms hereof by way of a U.S. Revolving Loan advance
     and a Multicurrency Revolving Loan advance on the Business Day following
     the date of such notice, in which case the Company shall be deemed to have
     requested a U.S. Revolving Loan advance and a Multicurrency Revolving Loan
     advance (such advances to be made under the U.S. Revolving Committed Amount
     and the Multicurrency Revolving Committed Amount on a pro rata basis based
     on the amount of each such Revolving Committed Amount) comprised solely of
     ABR Loans in the amount of such Swingline Loans; provided, however, that
     any such demand shall be deemed to have been given one Business Day prior
     to the Revolving Credit Termination Date and on the date of the occurrence
     of any Event of Default described in subsection 6.1(f) or subsection 6.1(g)
     and upon acceleration of the indebtedness hereunder and the exercise of
     remedies in accordance with the provisions of subsection 6.1. Each U.S.
     Lender and each Multicurrency Lender hereby irrevocably agrees to make its
     pro rata share of each such Revolving Credit Loan in the amount, in the
     manner and on the date specified in the preceding sentence notwithstanding
     (I) the amount of such borrowing may not comply with the minimum amount for
     advances of Revolving Credit Loans otherwise required hereunder, (II)
     whether any conditions specified in subsection 4.2 are then satisfied,
     (III) whether a Default or an Event of Default then exists, (IV) failure of
     any such request or deemed request for Revolving Credit Loan to be made by
     the time otherwise required hereunder, (V) whether the date of such
     borrowing is a date on which Revolving Credit Loans are otherwise permitted
     to be made hereunder or (VI) any termination of the Commitments relating
     thereto immediately prior to or contemporaneously with such borrowing. In
     the event that any U.S. Revolving Loan or any Multicurrency Revolving Loan
     cannot for any reason be made on the date otherwise required above
     (including, without limitation, as a result of the commencement of a
     proceeding under the Federal Bankruptcy Code (as now or hereafter in
     effect) with respect to the Company or any other Borrower), then each U.S.
     Lender and each Multicurrency Lender hereby agrees that it shall forthwith
     purchase (as of the date such borrowing would otherwise have occurred, but
     adjusted for any payments received from the Company on or after such date
     and prior to such purchase) from the Swingline Lender such Participation
     Interest in the outstanding Swingline Loans as shall be necessary to cause
     each such U.S. Lender and Multicurrency Lender to share in such Swingline
     Loans ratably based upon its respective Commitment Percentage (determined
     before giving effect to any termination of the Commitments pursuant to
     subsection 2.5), provided that (A) all interest payable on the Swingline
     Loans shall be for the account of the Swingline Lender until the date as of
     which the respective Participation Interest is purchased and (B) at the
     time any purchase of Participation Interests pursuant to this sentence is
     actually made, the purchasing Lender shall be required to pay to the
     Swingline Lender, to the extent not paid to the Swingline Lender by the
     Company in accordance with the terms of subsection (c)(ii) below, interest
     on the principal amount of Participation Interests purchased for each day
     from and including the day upon which such purchase of

                                       22

<PAGE>   40

     Participation Interests would otherwise have occurred to but excluding the
     date of actual payment for the purchase of such Participation Interests, at
     the rate equal to the Federal Funds Effective Rate (as defined in the
     definition of "ABR").

     (c)  Interest on Swingline Loans.

          (i) Subject to the provisions of subsection 2.9(e)(ii), each Swingline
     Loan shall bear interest at a per annum rate (computed on the basis of the
     actual number of days elapsed over a year of 360 or 365/366 days, as
     appropriate in accordance with the provisions of subsection 2.10(a)) equal
     to the ABR plus the Applicable Margin for Base Rate Loans.

          (ii) Payment of Interest. Interest on Swingline Loans shall be payable
     in arrears on each applicable Interest Payment Date (or at such other times
     as may be specified herein), unless accelerated sooner pursuant to
     subsection 6.1.

          (d)  Note Evidencing Swingline Loans. The Swingline Loans shall be
     evidenced by a duly executed Regular Note of the Company to the Swingline
     Lender in an original principal amount that includes the aggregate unpaid
     principal amount of all Swingline Loans.

2.16.    LETTER OF CREDIT SUBFACILITY.

     (a)  Issuance. The Issuing Lender has heretofore issued the Existing
Letters of Credit. Subject to the terms and conditions hereof and of the LOC
Documents, if any, and any other terms and conditions which the Issuing Lender
may reasonably require and in reliance upon the representations and warranties
set forth herein, the Issuing Lender agrees to issue, and each U.S. Lender and
each Multicurrency Lender severally agrees to participate in the issuance by the
Issuing Lender of, standby and trade Letters of Credit in U.S. Dollars from time
to time during the Commitment Period as the Company may request, in a form
acceptable to the Issuing Lender; provided, however, that (i) the LOC
Obligations outstanding shall not at any time exceed ONE HUNDRED MILLION DOLLARS
($100,000,000) (the "LOC Committed Amount") and (ii) the aggregate Dollar Amount
with respect to principal of outstanding U.S. Revolving Loans plus outstanding
Multicurrency Revolving Loans plus outstanding Swingline Loans plus all LOC
Obligations shall not exceed the sum of the U.S. Revolving Committed Amount plus
the Multicurrency Revolving Committed Amount. No Letter of Credit shall (x) have
an original expiry date more than one year from the date of issuance (other than
an Existing Letter of Credit) or (y) as originally issued or as extended, have
an expiry date extending beyond the Revolving Credit Termination Date. Each
Letter of Credit shall comply with the related LOC Documents. The issuance and
expiry dates of each Letter of Credit shall be a Business Day.

     (b)  Notice and Reports. The request for the issuance of a Letter of
Credit shall be submitted by the Company to the Issuing Lender at least three
(3) Business Days prior to the requested date of issuance. The Issuing Lender
will, at least quarterly and more frequently upon request, disseminate to each
of the U.S. Lenders and each of the Multicurrency Lenders a detailed report
specifying the Letters of Credit which are then issued and outstanding and any
activity with respect thereto which may have occurred since the date of the
prior report, and including therein, among other things, the beneficiary, the
face amount and the expiry date, as well as any payment or expirations which may
have occurred.

     (c)  Participation. Each U.S. Lender and each Multicurrency Lender,
upon issuance of a Letter of Credit, shall be deemed to have purchased without
recourse a Participation Interest from the Issuing Lender in such Letter of
Credit and the obligations arising thereunder and any collateral relating
thereto, in each case in an amount equal to its pro rata share of the
obligations under such Letter of Credit (based on the respective Commitment
Percentages of the U.S. Lenders and the Multicurrency Lenders) and shall
absolutely, unconditionally and irrevocably assume and be obligated to pay to
the Issuing

                                       23

<PAGE>   41

Lender and discharge when due, its pro rata share of the obligations arising
under such Letter of Credit in accordance with subsection 2.16(d) below. Without
limiting the scope and nature of each U.S. Lender's and each Multicurrency
Lender's Participation Interest in any Letter of Credit, to the extent that the
Issuing Lender has not been reimbursed as required hereunder or under any such
Letter of Credit, each such Lender shall pay to the Issuing Lender its pro rata
share of such unreimbursed drawing in same day funds on the day of notification
by the Issuing Lender of an unreimbursed drawing pursuant to the provisions of
subsection (d) below. The obligation of each U.S. Lender and each Multicurrency
Lender to so reimburse the Issuing Lender shall be absolute and unconditional
and shall not be affected by the occurrence of a Default, an Event of Default or
any other occurrence or event. Any such reimbursement shall not relieve or
otherwise impair the obligation of the Company to reimburse the Issuing Lender
under any Letter of Credit, together with interest as hereinafter provided.

     (d)  Reimbursement. In the event of any drawing under any Letter of
Credit, the Issuing Lender will promptly notify the Company. Unless the Company
shall immediately notify the Issuing Lender that the Company intends to
otherwise reimburse the Issuing Lender for such drawing, the Company shall be
deemed to have requested that the U.S. Lenders and the Multicurrency Lenders
make Revolving Credit Loans totaling the amount of the drawing as provided in
subsection (e) below on the related Letter of Credit, the proceeds of which will
be used to satisfy the related reimbursement obligations. The Company promises
to reimburse the Issuing Lender on the day of drawing under any Letter of Credit
(either with the proceeds of Revolving Credit Loans obtained hereunder or
otherwise) in same day funds. If the Company shall fail to reimburse the Issuing
Lender as provided hereinabove, the unreimbursed amount of such drawing shall
bear interest at a per annum rate equal to the ABR plus the Applicable Margin
for Base Rate Loans plus 2%. The Company's reimbursement obligations hereunder
shall be absolute and unconditional under all circumstances irrespective of any
rights of setoff, counterclaim or defense to payment the Company may claim or
have against the Issuing Lender, the Administrative Agent, the Lenders, the
beneficiary of the Letter of Credit drawn upon or any other Person, including
without limitation any defense based on any failure of the Company or any of its
Consolidated Subsidiaries to receive consideration or the legality, validity,
regularity or unenforceability of the Letter of Credit. The Issuing Lender will
promptly notify the U.S. Lenders and the Multicurrency Lenders of the amount of
any unreimbursed drawing and each U.S. Lender and each Multicurrency Lender
shall promptly pay to the Administrative Agent for the account of the Issuing
Lender in U.S. Dollars and in immediately available funds, the amount of such
Lender's pro rata share of such unreimbursed drawing. Such payment shall be made
on the day such notice is received by such Lender from the Issuing Lender if
such notice is received at or before 2:00 P.M. (Charlotte, North Carolina time)
otherwise such payment shall be made at or before 12:00 Noon (Charlotte, North
Carolina time) on the Business Day next succeeding the day such notice is
received. If such Lender does not pay such amount to the Issuing Lender in full
upon such request, such Lender shall, on demand, pay to the Administrative Agent
for the account of the Issuing Lender interest on the unpaid amount during the
period from the date of such drawing until such Lender pays such amount to the
Issuing Lender in full at a rate per annum equal to, if paid within two (2)
Business Days of the date that such Lender is required to make payments of such
amount pursuant to the preceding sentence, the Federal Funds Effective Rate (as
defined in the definition of "ABR") and thereafter at a rate equal to the ABR.
Each U.S. Lender's and each Multicurrency Lender's obligation to make such
payment to the Issuing Lender, and the right of the Issuing Lender to receive
the same, shall be absolute and unconditional, shall not be affected by any
circumstance whatsoever and without regard to the termination of this Agreement
or the Commitments hereunder, the existence of a Default or Event of Default or
the acceleration of the obligations of the Company hereunder and shall be made
without any offset, abatement, withholding or reduction whatsoever.
Simultaneously with the making of each such payment by a Lender to the Issuing
Lender, such Lender shall, automatically and without any further action on the
part of the Issuing Lender or such Lender, acquire a Participation Interest in
an amount equal to such payment (excluding the portion of such payment
constituting interest owing to the Issuing Lender) in the related unreimbursed
drawing

                                       24

<PAGE>   42

portion of the LOC Obligation and in the interest thereon and in the related LOC
Documents, and shall have a claim against the Company with respect thereto.

     (e)  Repayment with Revolving Credit Loans. On any day on which the
Company shall have requested, or been deemed to have requested, a U.S. Revolving
Loan advance and a Multicurrency Revolving Loan Advance to reimburse a drawing
under a Letter of Credit, the Administrative Agent shall give notice to the U.S.
Lenders and the Multicurrency Lenders that a U.S. Revolving Loan and a
Multicurrency Revolving Loan (such loans to be made under the U.S. Revolving
Committed Amount and the Multicurrency Revolving Committed Amount on a pro rata
basis based on the amount of each such Revolving Committed Amount) have been
requested or deemed requested by the Company to be made in connection with a
drawing under a Letter of Credit, in which case a U.S. Revolving Loan advance
and a Multicurrency Revolving Loan advance, each comprised of ABR Loans (or
Eurodollar Loans denominated in U.S. Dollars to the extent the Company has
complied with the procedures of subsection 2.3(a) with respect thereto), shall
be immediately made to the Company by all U.S. Lenders and all Multicurrency
Lenders, as applicable (notwithstanding any termination of the Commitments
pursuant to subsection 6.1), pro rata based on their respective Commitment
Percentages (determined before giving effect to any termination of the
Commitments pursuant to subsection 6.1) and the proceeds thereof shall be paid
directly to the Issuing Lender for application to the respective LOC
Obligations. Each such Lender hereby irrevocably agrees to make its pro rata
share of each such Revolving Credit Loan immediately upon any such request or
deemed request in the amount, in the manner and on the date specified in the
preceding sentence notwithstanding (i) the amount of such borrowing may not
comply with the minimum amount for advances of Revolving Credit Loans otherwise
required hereunder, (ii) whether any conditions specified in subsection 4.2 are
then satisfied, (iii) whether a Default or an Event of Default then exists, (iv)
failure for any such request or deemed request for Revolving Credit Loan to be
made by the time otherwise required hereunder, (v) whether the date of such
borrowing is a date on which Revolving Credit Loans are otherwise permitted to
be made hereunder or (vi) any termination of the Commitments relating thereto
immediately prior to or contemporaneously with such borrowing. In the event that
any U.S. Revolving Loan or any Multicurrency Revolving Loan cannot for any
reason be made on the date otherwise required above (including, without
limitation, as a result of the commencement of a proceeding under the Bankruptcy
Code with respect to the Company or any of its Consolidated Subsidiaries), then
each such Lender hereby agrees that it shall forthwith purchase (as of the date
such borrowing would otherwise have occurred, but adjusted for any payments
received from the Company on or after such date and prior to such purchase) from
the Issuing Lender such Participation Interests in the outstanding LOC
Obligations as shall be necessary to cause each such U.S. Lender and
Multicurrency Lender to share in such LOC Obligations ratably (based upon the
respective Commitment Percentages of such Lenders (determined before giving
effect to any termination of the Commitments pursuant to subsection 6.1)),
provided that at the time any purchase of Participation Interests pursuant to
this sentence is actually made, the purchasing Lender shall be required to pay
to the Issuing Lender, to the extent not paid to the Issuer by the Company in
accordance with the terms of subsection (d) above, interest on the principal
amount of Participation Interests purchased for each day from and including the
day upon which such borrowing would otherwise have occurred to but excluding the
date of payment for such Participation Interests, at the rate equal to, if paid
within two (2) Business Days of the date of the Revolving Credit Loan advance,
the Federal Funds Effective Rate (as defined in the definition of "ABR"), and
thereafter at a rate equal to the ABR.

     (f)  Designation of Consolidated Subsidiaries as Account Parties.
Notwithstanding anything to the contrary set forth in this Agreement, including
without limitation subsection 2.16(a), a Letter of Credit issued hereunder may
contain a statement to the effect that such Letter of Credit is issued for the
account of a Consolidated Subsidiary of the Company, provided that
notwithstanding such statement, the Company shall be the actual account party
for all purposes of this Agreement for such Letter of Credit

                                       25

<PAGE>   43

and such statement shall not affect the Company's reimbursement obligations
hereunder with respect to such Letter of Credit.

     (g)  Renewal, Extension. The renewal or extension of any Letter of Credit
shall, for purposes hereof, be treated in all respects the same as the issuance
of a new Letter of Credit hereunder.

     (h)  Uniform Customs and Practices. The Issuing Lender may have the Letters
of Credit be subject to The Uniform Customs and Practice for Documentary
Credits, as published as of the date of issue by the International Chamber of
Commerce (Publication No. 500 or the most recent publication, the "UCP"), in
which case the UCP may be incorporated therein and deemed in all respects to be
a part thereof.

     (i) Indemnification; Nature of Issuing Lender's Duties.

          (i) In addition to its other obligations under this subsection 2.16,
     the Company hereby agrees to pay, and protect, indemnify and save each U.S.
     Lender and each Multicurrency Lender (including the Issuing Lender)
     harmless from and against, any and all claims, demands, liabilities,
     damages, losses, costs, charges and expenses (including reasonable
     attorneys' fees and expenses) that such Lender may incur or be subject to
     as a consequence, direct or indirect, of (A) the issuance of any Letter of
     Credit or (B) the failure of such Lender or the Issuing Lender to honor a
     drawing under a Letter of Credit as a result of any act or omission,
     whether rightful or wrongful, of any present or future de jure or de facto
     government or Governmental Authority (all such acts or omissions, herein
     called "Government Acts").

          (ii) As between (x) the Company and (y) the U.S. Lenders and the
     Multicurrency Lenders (including the Issuing Lender), the Company shall
     assume all risks of the acts, omissions or misuse of any Letter of Credit
     by the beneficiary thereof. No Lender (including the Issuing Lender) shall
     be responsible: (A) for the form, validity, sufficiency, accuracy,
     genuineness or legal effect of any document submitted by any party in
     connection with the application for and issuance of any Letter of Credit,
     even if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent or forged; (B) for the validity or
     sufficiency of any instrument transferring or assigning or purporting to
     transfer or assign any Letter of Credit or the rights or benefits
     thereunder or proceeds thereof, in whole or in part, that may prove to be
     invalid or ineffective for any reason; (C) for errors, omissions,
     interruptions or delays in transmission or delivery of any messages, by
     mail, cable, telegraph, telex or otherwise, whether or not they be in
     cipher; (D) for any loss or delay in the transmission or otherwise of any
     document required in order to make a drawing under a Letter of Credit or of
     the proceeds thereof; and (E) for any consequences arising from causes
     beyond the control of such Lender, including, without limitation, any
     Government Acts. None of the above shall affect, impair, or prevent the
     vesting of the Issuing Lender's rights or powers hereunder.

          (iii) In furtherance and extension and not in limitation of the
     specific provisions hereinabove set forth, any action taken or omitted by
     any U.S. Lender or any Multicurrency Lender (including the Issuing Lender),
     under or in connection with any Letter of Credit or the related
     certificates, if taken or omitted in good faith, shall not put such Lender
     under any resulting liability to the Company. It is the intention of the
     parties that this Agreement shall be construed and applied to protect and
     indemnify each U.S. Lender and each Multicurrency Lender (including the
     Issuing Lender) against any and all risks involved in the issuance of the
     Letters of Credit, all of which risks are hereby assumed by the Company (on
     behalf of itself and each of its Consolidated Subsidiaries), including,
     without limitation, any and all Government Acts. No U.S. Lender or
     Multicurrency Lender (including the Issuing Lender) shall, in any way, be
     liable for

                                       26

<PAGE>   44

     any failure by such Lender or anyone else to pay any drawing under any
     Letter of Credit as a result of any Government Acts or any other cause
     beyond the control of such Lender.

          (iv) Nothing in this subsection (i) is intended to limit the
     reimbursement obligations of the Company contained in subsection (d) above.
     The obligations of the Company under this subsection (i) shall survive the
     termination of this Agreement. No act or omission of any current or prior
     beneficiary of a Letter of Credit shall in any way affect or impair the
     rights of the U.S. Lenders and the Multicurrency Lenders (including the
     Issuing Lender) to enforce any right, power or benefit under this
     Agreement.

          (v) Notwithstanding anything to the contrary contained in this
     subsection (i), the Company shall have no obligation to indemnify any U.S.
     Lender or Multicurrency Lender (including the Issuing Lender) in respect of
     any liability incurred by such Lender (A) to the extent such liability
     arose out of the gross negligence or willful misconduct of such Lender, as
     determined by a court of competent jurisdiction, or (B) caused by such
     Lender's failure to pay under any Letter of Credit after presentation to it
     of a request strictly complying with the terms and conditions of such
     Letter of Credit, as determined by a court of competent jurisdiction,
     unless such payment is prohibited by any law, regulation, court order or
     decree.

     (j)  Responsibility of Issuing Lender. It is expressly understood and
agreed that the obligations of the Issuing Lender hereunder to the U.S. Lenders
and the Multicurrency Lenders are only those expressly set forth in this
Agreement and that the Issuing Lender shall be entitled to assume that the
conditions precedent set forth in subsection 4.2 have been satisfied unless it
shall have acquired actual knowledge that any such condition precedent has not
been satisfied; provided, however, that nothing set forth in this subsection
2.16 shall be deemed to prejudice the right of any U.S. Lender or Multicurrency
Lender to recover from the Issuing Lender any amounts made available by such
Lender to the Issuing Lender pursuant to this subsection 2.16 in the event that
it is determined by a court of competent jurisdiction that the payment with
respect to a Letter of Credit constituted gross negligence or willful misconduct
on the part of the Issuing Lender.

     (k)  Conflict with LOC Documents. In the event of any conflict between
this Agreement and any LOC Document (including any letter of credit
application), this Agreement shall control.

2.17.    TERM LOAN TRANCHES.

     (a)  Term Loan Commitments. Subject to the terms and conditions hereof and
in reliance upon the representations and warranties set forth herein:

     (i) certain of the Lenders severally made available to the Company in U.S.
Dollars on the Closing Date such Lenders' Commitment Percentages of each of the
following term loan tranches:

          (A) A TERM LOAN IN THE AGGREGATE PRINCIPAL AMOUNT OF ONE BILLION TWO
     HUNDRED FIFTY MILLION DOLLARS ($1,250,000,000) OF WHICH $874,696,132.59
     SHALL BE OUTSTANDING AS OF THE THIRD AMENDMENT EFFECTIVE DATE, AFTER GIVING
     EFFECT TO THE THIRD AMENDMENT (THE "TRANCHE A TERM LOAN");

          (B) A TERM LOAN IN THE AGGREGATE PRINCIPAL AMOUNT OF FIVE HUNDRED
     MILLION DOLLARS ($500,000,000) (THE "TRANCHE B TERM LOAN") WHICH WAS REPAID
     IN FULL PRIOR TO THE THIRD AMENDMENT EFFECTIVE DATE; AND

          (C) A TERM LOAN IN THE AGGREGATE PRINCIPAL AMOUNT OF ONE BILLION
     DOLLARS ($1,000,000,000) WHICH SHALL HAVE BEEN REPAID IN FULL AS OF THE
     THIRD AMENDMENT EFFECTIVE DATE, AFTER GIVING EFFECT TO THE THIRD AMENDMENT
     (THE "TRANCHE C TERM LOAN"), AND

<PAGE>   45
         (II).....EACH TRANCHE D LENDER SEVERALLY AGREES TO MAKE AVAILABLE TO
THE COMPANY IN U.S. DOLLARS ON THE THIRD AMENDMENT EFFECTIVE DATE SUCH TRANCHE D
LENDER'S COMMITMENT PERCENTAGE OF AN ADDITIONAL TERM LOAN TRANCHE CONSISTING OF
A TERM LOAN IN THE AGGREGATE PRINCIPAL AMOUNT OF THREE HUNDRED SEVENTY FIVE
MILLION DOLLARS ($375,000,000) (THE "TRANCHE D TERM LOAN").

         Each such term loan tranche referred to above (each a "Term Loan
Tranche") may consist of ABR Loans or Eurodollar Loans, or a combination
thereof, as the Company may request; provided that any portion of the Tranche A
Term Loan funded in Euros in accordance with the terms set forth below shall
consist solely of Eurodollar Loans. Except as set forth below with respect to
the Tranche A Term Loan, amounts repaid under a Term Loan Tranche may not be
reborrowed.

         On the Restatement Effective Date and in accordance with the borrowing
procedures set forth in subsection (b) below, the Company converted $950,000,000
of the Tranche A Term Loan to Term Loans denominated in Euros by requesting a
readvance in Euros of $950,000,000 of the Tranche A Term Loan and, upon receipt
of such readvance, immediately repaying to the Administrative Agent the Dollar
Amount of such readvance in U.S. Dollars. The Term Loans converted on the
Restatement Effective Date pursuant to the preceding sentence shall continue to
constitute a portion of the Tranche A Term Loan.

         On the First Amendment Effective Date and in accordance with the
borrowing procedures set forth in subsection (b) below, the Company converted
the entire portion of the Tranche A Term Loan then denominated in Euros, equal
in Dollar Amount to $950,000,000, to Term Loans denominated in U.S. Dollars by
requesting a readvance in U.S. Dollars of such portion of the Tranche A Term
Loan and, upon receipt of such readvance, immediately repaying to the
Administrative Agent such portion of the Tranche A Term Loan designated for
conversion in Euros. The Term Loans converted on the First Amendment Effective
Date pursuant to the preceding sentence shall continue to constitute a portion
of the Tranche A Term Loan.

         (b)......Borrowing Procedures. The funding of the Tranche A Term Loan,
the Tranche B Term Loan and Tranche C Term Loan on the Closing Date was, and the
funding of the Tranche D Term Loan on the Third Amendment Effective Date shall
be, subject to the following procedures: The Company shall submit an appropriate
notice of borrowing, substantially in the form of Exhibit G, to the
Administrative Agent not later than 11:00 A.M. (Charlotte, North Carolina time)

respect to the portion of each Term Loan Tranche initially consisting of an ABR
Loan, or on the third Business Day prior to the Closing Date or the Third
Amendment Effective Date, as applicable, with respect to the portion of each
Term Loan Tranche initially consisting of one or more Eurodollar Loans, which
notice of borrowing shall be irrevocable and shall specify (i) that the funding
of a Term Loan Tranche is requested and (ii) whether the funding of such Term
Loan Tranche shall be comprised of ABR Loans, Eurodollar Loans or a combination
thereof, and if Eurodollar Loans are requested, the Interest Period(s) therefor.
If the Company shall fail to deliver such notice of borrowing to the
Administrative Agent by 11:00 A.M. (Charlotte, North Carolina time) on the third
Business Day prior to the Closing Date or the Third Amendment Effective Date, as
applicable, then the full amount of each Term Loan Tranche shall be disbursed on
the Closing Date or the Third Amendment Effective Date, as applicable, as an ABR
Loan. Each Lender shall make its Commitment Percentage of each Term Loan Tranche
available to the Administrative Agent for the account of the Company at the
office of the Administrative Agent specified in subsection 9.2, or at such other
office as the Administrative Agent may designate in writing, by 1:00 P.M.
(Charlotte, North Carolina time) on the Closing Date or the Third Amendment
Effective Date, as applicable, in U.S. Dollars and in funds immediately
available to the Administrative Agent. Each Term Loan Tranche 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 Lenders and in
like funds as received by the Administrative Agent.

         The conversion of a portion of the Tranche A Term Loan on the
Restatement Effective Date was subject to the following procedures: The Company
shall submit an appropriate notice of borrowing, substantially in the form of
Exhibit G, to the Administrative Agent not later than 11:00 A.M. (Charlotte,
North Carolina time) on the third Business Day prior to the Restatement
Effective Date with respect to the portion of the Tranche A Term Loan to be
redenominated in Euros, which notice of borrowing shall be irrevocable and shall
specify (i) that a readvance in Euros of a portion of the Tranche A Term Loan is
requested on the Restatement Effective Date, (ii) the Dollar Amount of such
requested readvance (which may not exceed $950 million) (the "Readvance Amount")
and (iii) the requested Interest Period(s) for the Eurodollar Loans comprising
such readvance. The Administrative Agent will notify the Tranche A Euro Lenders
of such readvance request and will, by no later than the second Business Day
prior to the Restatement Effective Date, notify each Tranche A Euro Lender of
the amount of Euros to be funded by such Tranche A Euro Lender on the
Restatement Effective Date in order to effectuate such readvance (each such
amount a "Tranche A Euro Amount"). The amount of Euros to be funded by each
Tranche A Euro Lender shall not exceed that portion of such Lender's Commitment
under the Tranche A Term Loan available to be readvanced in Euros, as indicated
on Schedule I and as expressed in Euros based on the Administrative Agent's spot
rate of exchange two Business Days prior to the Restatement Effective Date. Each
Tranche A Euro Lender shall make its Tranche A Euro Amount available to the
Administrative Agent for the account of the Company at the U.K. Lending Office
of the Administrative Agent specified below, or at such other address as the
Administrative Agent may specify to the Tranche A Euro Lenders and the Company,
by 11:00 A.M. (London time) on the Restatement Effective Date, in Euros, and in
funds immediately available to the Administrative Agent. Upon confirmation by
the Administrative Agent of its receipt of a Tranche A Euro Lender's Tranche A
Euro Amount in Euros, the Administrative Agent will, on the Restatement
Effective Date, distribute to the Company such Lender's Tranche A Euro Amount in
Euros. On the Restatement Effective Date and immediately upon its receipt of the
respective Tranche A Euro Amounts referred to above, the Company shall pay to
the Administrative Agent, for the pro rata benefit of the Tranche A Euro Lenders
and in U.S. Dollars, the Readvance Amount; provided, however, that if the
Administrative Agent has not made available to the Company any Lender's Tranche
A Euro Amount in Euros on the Restatement Effective Date, then the Company may
withhold from the amount otherwise payable to the Administrative Agent pursuant
to this sentence such Lender's pro rata portion of the Readvance Amount until
such time as such Lender's Tranche A Euro Amount has been made available to the
Company.

will notify the Tranche A Converting Lenders of such readvance request and will,
by no later than the second Business Day prior to the First Amendment Effective
Date, notify each Tranche A Converting Lender of the amount of U.S. Dollars to

such time as such Lender's Tranche A Conversion Amount has been made available
to the Company.

         (c)......Minimum Amounts. Each Eurodollar Loan or ABR Loan that is part
of a Term Loan Tranche shall be in an aggregate principal Dollar Amount that is
not less than $5,000,000 and in an integral multiple of $1,000,000 or 1,000,000
Euros, as applicable (or the then remaining principal balance of that portion of
such Term Loan Tranche available in such currency, if less).

         (e)......Interest. Each Term Loan Tranche shall bear interest, and such
interest shall be payable, as specified in subsection 2.9.

         (f)......Notes Evidencing Term Loans. The Term Loans made by each
Lender shall be evidenced by a duly executed Note in the form of Exhibit A or,
in the case of the Tranche D Term Loans, Exhibit A(amd) (each, as amended,
modified, restated, supplemented, extended, renewed or replaced from time to

2.18.    BANKERS' ACCEPTANCES.

         (a)......Form.

                  (i) To facilitate the acceptance of Bankers' Acceptances
         hereunder, the Canadian Borrower hereby appoints each Canadian Lender
         as its attorney to sign and endorse on its behalf, as and when
         considered necessary by such Canadian Lender, an appropriate number of
         orders in the form prescribed by that Canadian Lender.

                  (ii) Each Canadian Lender may, at its option, execute any
         order in handwriting or by the facsimile or mechanical signature of any
         of its authorized officers, and the Canadian Lenders

                                       32

<PAGE>   50

         are hereby authorized to accept or pay, as the case may be, any order
         of the Canadian Borrower which purports to bear such a signature
         notwithstanding that any such individual has ceased to be an authorized
         officer of the Canadian Lender. Any such order or Bankers' Acceptance
         shall be as valid as if he or she were an authorized officer at the
         date of issue of the order or Bankers' Acceptance.

                  (iii) Any order signed by a Canadian Lender as attorney for
         the Canadian Borrower, whether signed in handwriting or by the
         facsimile or mechanical signature of an authorized officer of a
         Canadian Lender may be dealt with by the Canadian Administrative Agent
         or any Canadian Lender to all intents and purposes and shall bind the
         Canadian Borrower as if duly signed and issued by the Canadian
         Borrower.

                  (iv) The receipt by the Canadian Administrative Agent of a
         notice under section 2.18(c) requesting Bankers' Acceptances shall be
         each Canadian Lender's sufficient authority to execute, and each
         Canadian Lender shall, subject to the terms and conditions of this
         Agreement, execute orders in accordance with such request, and the
         orders so executed shall thereupon be deemed to have been presented for
         acceptance.

         (b)......Issuance. Subject to the terms and conditions hereof and of
the BA Documents executed in connection with the creation of each Banker's
Acceptance and any other terms and conditions which the Canadian Lenders may
reasonably require, (so long as such terms and conditions do not impose any
financial obligation on or require any Lien (not otherwise contemplated by this
Agreement) to be given by the Company or any of its Subsidiaries or conflict
with any obligation of, or detract from any action which may be taken by, the
Company or any of its Subsidiaries under this Agreement) each Canadian Lender
agrees, severally and not jointly, at any time and from time to time during the
Commitment Period, to create Bankers' Acceptances by accepting orders of the
Canadian Borrower presented to it for acceptance equal to such Canadian Lender's
Commitment Percentage of such Bankers' Acceptances as the Canadian Borrower may
request on such date; provided, however, that (i) the aggregate Dollar Amount of
(A) Canadian Revolving Loans outstanding plus (B) the Face Amount of Bankers'
Acceptances outstanding may not exceed the Canadian Revolving Committed Amount
and (ii) if the Face Amount of a Banker's Acceptance, which would otherwise be
accepted by a Canadian Lender, would not be C$100,000 or a larger multiple
thereof, such Face Amount shall be increased or reduced by the Canadian
Administrative Agent in its discretion to the nearest multiple of C$100,000.
Upon the acceptance of any order of the Canadian Borrower pursuant hereto, the
Canadian Borrower shall pay to each of the Canadian Lenders, in advance, the
Acceptance Fee. Forthwith after each request for drawdown of, continuation of or
conversion into Bankers' Acceptances, the Canadian Administrative Agent shall
notify each Canadian Lender of the amount of Bankers' Acceptances to be accepted
by such Canadian Lender. The Canadian Lenders may, but are not obligated to,
purchase any of the Bankers' Acceptances. The Canadian Borrower shall as soon as
practical deliver to the Canadian Administrative Agent a notice confirming the
issuance of Bankers' Acceptances and specifying the BA Discount Proceeds derived
therefrom. For greater certainty, with respect to each extension of credit by
way of Bankers' Acceptances, each Bankers' Acceptance shall have the same term
and, upon sale, each Bankers' Acceptance shall be discounted at the rate
relating to the Canadian Lender accepting the Bankers' Acceptance.

         (c)......Requirements of Bankers' Acceptances. Each Bankers' Acceptance
shall comply with the related BA Documents and shall be executed by the Canadian
Borrower and presented to the Canadian Lenders pursuant to such procedures as
are provided for in such BA Documents or as otherwise provided or required by a
Canadian Lender. The creation and maturity date of each Bankers' Acceptance
shall be a Business Day and no Bankers' Acceptance shall have a maturity date
later than the Revolving Credit Termination Date.

                                       33

<PAGE>   51

         (d)......Method of Requesting a Bankers' Acceptance. By no later than
10:00 A.M., Toronto, Ontario time, two Business Days prior to the date of the
requested Bankers' Acceptance, the Canadian Borrower shall submit an irrevocable
notice, substantially in the form of Exhibit F, to the Canadian Administrative
Agent setting forth the aggregate amount of Bankers' Acceptances requested and
the maturity date of the requested Bankers' Acceptances which shall be 30, 60,
90 or 180 days, at the election of the Canadian Borrower, and complying in all
respects with subsection 4.2.

         (e)......Safekeeping of Orders. Any executed orders to be used as
Bankers' Acceptances which are delivered to a Canadian Lender shall be held in
safekeeping with the same degree of care as if they were such Canadian Lender's
own property, and shall be kept at the place at which such orders are ordinarily
held by such Canadian Lender, provided that such Canadian Lender shall not be
deemed to be an insurer thereof.

         (f)......Maturity/Continuations. The Canadian Borrower shall pay to the
Canadian Administrative Agent, and there shall become due and payable, at 1:00
P.M. (Toronto, Ontario time) on the maturity date for each Bankers' Acceptance
an amount in Canadian Dollars in same day funds equal to the Face Amount of such
Bankers' Acceptance (notwithstanding that any Canadian Lender which accepted any
such Bankers' Acceptance may be the holder thereof at maturity); provided,
however, that subject to subsection 3.1 and provided that the Canadian Borrower
has, by giving notice in accordance with subsection 2.18(c) or 2.7, requested
the Canadian Lenders to accept its orders to replace all or a portion of
outstanding Bankers' Acceptances as they mature, each Canadian Lender shall, on
the maturity of such Bankers' Acceptances and concurrent with the payment by the
Canadian Borrower to the Canadian Lenders of the Face Amount of such Bankers'
Acceptances or the portion thereof to be replaced, accept the Canadian
Borrower's order(s) having an aggregate Face Amount equal to its pro rata share
of the aggregate Face Amount of the matured Bankers' Acceptances or the portion
thereof to be replaced.

         (g)......Repayments Prior to Maturity. Except as required by subsection
2.6(b), no repayment of a Bankers' Acceptance shall be made by the Canadian
Borrower to the Canadian Lenders prior to the maturity date thereof. Any such
repayment required by subsection 2.6(b) shall be made to the Canadian
Administrative Agent and such monies shall be held by the Canadian
Administrative Agent, in a cash collateral account hypothecated to the Canadian
Administrative Agent, to be paid to each of the Canadian Lenders on the maturity
date of the Bankers' Acceptances which have been accepted by it. The Canadian
Borrower shall be entitled to the benefit of any interest accruing thereon, in
each case, on the respective maturity date of each Bankers' Acceptance in
respect of which repayment is made, and upon the maturity of each such Bankers'
Acceptance the Canadian Lenders shall apply the interest thereon in payment of
amounts owed by the Canadian Borrower hereunder. Any such payment by the
Canadian Borrower to the Canadian Lenders shall satisfy the Canadian Borrower's
obligations under the Bankers' Acceptance to which it relates and the Canadian
Lender which has accepted such Bankers' Acceptance shall thereafter be solely
responsible for the payment of such Bankers' Acceptance.

         (h)......Minimum Amounts. Each request for Bankers' Acceptances shall
be in a minimum aggregate amount of C$1,000,000 and in an integral multiple of
C$1,000,000 above such amount. The Face Amount of each Bankers' Acceptance
created hereunder shall be C$100,000 or any multiple thereof.

         (i)......Funding of Bankers' Acceptances.

                  (i) Subject to subsections (ii) and (iii) below, each Canadian
         Lender shall, not later than 1:00 P.M., Toronto, Ontario time, on the
         date of creation of the Bankers' Acceptances, accept orders of the
         Canadian Borrower which are presented to it for acceptance in an amount

                                       34

<PAGE>   52

         equal to each Canadian Lender's Commitment Percentage of the aggregate
         Face Amounts of Bankers' Acceptances created on such date; provided,
         however, that if the Face Amount of a Banker's Acceptance, which would
         otherwise be accepted by a Canadian Lender, would not be C$100,000 or a
         larger multiple thereof, such Face Amount shall be increased or reduced
         by the Canadian Administrative Agent in its discretion to the nearest
         multiple of C$100,000. Subject to the provisions hereof, the Canadian
         Administrative Agent shall be responsible for making all necessary
         arrangements with each of the Canadian Lenders with respect to the
         acceptance of Bankers' Acceptances.

                  (ii) Each Canadian Lender shall transfer to the Canadian
         Administrative Agent for value on such creation date immediately
         available Canadian Dollars in an aggregate amount equal to the BA
         Discount Proceeds of all Bankers' Acceptances accepted and sold or
         purchased by the Canadian Lender on such date net of the applicable
         Acceptance Fee and net of the amount required to pay any of its
         previously accepted Bankers' Acceptances that are maturing on such date
         or its percentage of any Canadian Base Rate Revolving Loan that is
         being converted to Bankers' Acceptances on such date.

                  (iii) Subject to subsection 3.1, in the sole judgment of a
         Canadian Lender, if such Canadian Lender is unable to create a Bankers'
         Acceptance in accordance with this Agreement, such Canadian Lender
         shall give an irrevocable notice to such effect to the Canadian
         Administrative Agent and the Canadian Borrower prior to 10:00 A.M.,
         Toronto, Ontario time, on the date of the requested creation of the
         Bankers' Acceptances. Such Canadian Lender shall make available to the
         Canadian Borrower prior to 1:00 P.M., Toronto, Ontario time, one
         Business Day prior to the date of such requested Bankers' Acceptance a
         Canadian Dollar loan in a principal amount equal to the BA Discount
         Proceeds of such Canadian Lender's pro rata share of the aggregate Face
         Amounts of Bankers' Acceptances to be created on such date, such loan
         to be funded in the same manner as the Bankers' Acceptances provided by
         the other Canadian Lenders. Such loan shall have the same term as the
         Bankers' Acceptance for which it is a substitute and shall bear such
         interest per annum throughout the term thereof as shall permit such
         Canadian Lender to obtain the same effective rate as if such Canadian
         Lender had accepted and purchased a Bankers' Acceptance at the same
         Acceptance Fee and pricing in which the Canadian Administrative Agent
         would have accepted and purchased on the bid side of the market, such
         Bankers' Acceptance at approximately 1:00 P.M., Toronto, Ontario time,
         on the date such loan is made. The Canadian Borrower hereby agrees that
         if such loan is made by a Canadian Lender interest shall be payable in
         advance on the date of such loan by deducting the interest payable in
         respect thereof from the principal amount of such loan.

         The Canadian Administrative Agent shall promptly inform the
Administrative Agent of the creation of Bankers' Acceptances and the terms
thereof. No Canadian Lender shall be responsible for the failure or delay by any
other Canadian Lender in its obligation to create Bankers' Acceptances
hereunder; provided, however, that the failure of any Canadian Lender to fulfill
its Commitment hereunder shall not relieve any other Canadian Lender of its
Commitment hereunder.

         SECTION 3.........CHANGE IN CIRCUMSTANCES AFFECTING LOANS OR BANKERS'
ACCEPTANCES.

         3.1. BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR;
INABILITY TO CREATE BANKERS' ACCEPTANCES.

         (a)......If before the beginning of any Interest Period applicable to a
Eurodollar Loan:

                  (i) by reason of circumstances affecting the interbank
         eurodollar market generally, deposits in U.S. Dollars or Euros (in the
         applicable amounts) are not being offered by the Administrative Agent
         in the interbank eurodollar market for such Interest Period;

                                       35

<PAGE>   53

                  (ii) the Required Lenders shall determine that the Eurodollar
         Rate determined or to be determined for such Interest Period will not
         adequately and fairly reflect the cost to such Lenders of maintaining
         or funding, for such Interest Period, its Eurodollar Loans to which
         such Interest Period applies; or

                  (iii) the Administrative Agent is unable to determine the
         London Interbank Offered Rate;

the Administrative Agent (upon receipt of notice from the Required Lenders in
the case of clause (ii) above) shall forthwith give notice thereof to the
Company whereupon until the Administrative Agent notifies the Company that the
circumstances giving rise to such suspension no longer exist (A) the obligations
of the Lenders to make the affected Eurodollar Loans shall be suspended and (B)
each Borrower shall repay in full the then outstanding principal amount of each
affected Eurodollar Loan received by it, together with accrued interest thereon,
on the last day of the then current Interest Period applicable to such Loan or
convert the then outstanding principal amount of each Eurodollar Loan on the
last day of the then current Interest Period applicable to such Loan to an ABR
Loan.

         (b)......If the Canadian Administrative Agent determines in good faith,
which determination shall be final, conclusive and binding upon the Canadian
Borrower absent manifest error, and notifies the Canadian Borrower and each of
the Canadian Lenders that, by reason of circumstances affecting the money market
or the market for bankers' acceptances generally (i) there is no market for
Bankers' Acceptances; or (ii) the demand for Bankers' Acceptances is
insufficient to allow the sale or trading of the Bankers' Acceptances created
and purchased hereunder, then,

                  (A) THE RIGHT OF THE CANADIAN BORROWER TO REQUEST A BORROWING
         BY WAY OF BANKERS' ACCEPTANCES SHALL BE SUSPENDED UNTIL THE CANADIAN
         ADMINISTRATIVE AGENT DETERMINES IN GOOD FAITH THAT THE CIRCUMSTANCES
         CAUSING SUCH SUSPENSION NO LONGER EXIST AND THE CANADIAN ADMINISTRATIVE
         AGENT SO NOTIFIES THE CANADIAN BORROWER; AND

                  (B) ANY NOTICE OF REQUESTED BANKERS' ACCEPTANCES WHICH IS
         OUTSTANDING SHALL BE CANCELED AND THE BANKERS' ACCEPTANCE REQUESTED
         THEREIN SHALL NOT BE MADE.

                  (C) THE CANADIAN ADMINISTRATIVE AGENT SHALL PROMPTLY NOTIFY
         THE CANADIAN BORROWER OF THE SUSPENSION OF THE CANADIAN BORROWER'S
         RIGHT TO REQUEST A BANKERS' ACCEPTANCE AND OF THE TERMINATION OF ANY
         SUCH SUSPENSION.

3.2.     ILLEGALITY.

         If, after the date of this Agreement, the introduction of, or any
change in, any applicable law, rule or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof or compliance by any Lender with any
request or directive (whether or not having the force of law) of any such
Governmental Authority shall make it unlawful or impossible for any Lender to
make, maintain or fund its Eurodollar Loans, such Lender forthwith shall so
notify the Company. Upon receipt of such notice, each Borrower shall prepay in
full the then outstanding principal amount of each Eurodollar Loan of such
Lender received by it, together with accrued interest thereon, or convert the
then outstanding principal amount of each such Eurodollar Loan to an ABR Loan,
in either case, on either (a) the last day of the then current Interest Period
applicable to such Eurodollar Loan if such Lender may lawfully continue to
maintain and fund such Loan to such day or (b) immediately if such Lender may
not lawfully continue to fund and maintain such Loan to such day.

3.3.     INCREASED COST.

         (a)......If, after the date of this Agreement, the introduction of, or
any change in, any applicable law, rule or regulation or in the interpretation
or administration thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof or

                                       36

<PAGE>   54

compliance by any Lender with any request or directive of any such Governmental
Authority, central bank or comparable agency (whether or not having the force of
law):

                  (i) shall subject any Lender to any tax, duty or other charge
         with respect to Loan made by it, any Letter of Credit or any Bankers'
         Acceptance, or its obligation to make, issue or create any of the
         foregoing, or shall change the basis of taxation of payments to such
         Lender of the principal of or interest on Loan made by it, any Letter
         of Credit or any Bankers' Acceptance, or its obligation to make, issue
         or create any of the foregoing (except for changes in the rate of tax
         on the overall net income of such Lender imposed by the jurisdiction,
         at any level, in which the principal executive office of such Lender is
         located); or

                  (ii) shall impose, modify or deem applicable any reserve
         (including, without limitation, any reserve imposed by the Board of
         Governors of the Federal Reserve System), special deposit or similar
         requirement against assets of, deposits with or for the account of, or
         credit extended by, any Lender or shall impose on any Lender or the
         interbank eurodollar market any other condition affecting its
         Eurodollar Loans or its respective Notes;

and the result of any of the foregoing is to increase the cost to such Lender of
making or maintaining its Loans or issuing or participating in Letters of Credit
or creating Bankers' Acceptances, or to reduce the amount of any sum received or
receivable by such Lender under this Agreement or under its Notes in respect
thereof, by any amount deemed by such Lender to be material, then, within
fifteen (15) days after receipt of written demand from such Lender, the
Borrowers agree to pay to such Lender such additional amount or amounts as will
compensate such Lender for such increased cost or reduction. A certificate of
such Lender setting forth in reasonable detail the basis for determining such
additional amount or amounts necessary to compensate such Lender shall be
conclusive in the absence of manifest error.

         (b)......If any Lender shall have determined that the introduction of
any applicable law, rule, regulation or guideline regarding capital adequacy, or
any change therein or any change in the interpretation or administration 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) of any such
Governmental Authority, central bank or comparable agency, affects or would
affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and such Lender (taking into
consideration such Lender's or such corporation's policies with respect to
capital adequacy and such Lender's desired return on capital) determines that
the amount of such capital is increased as a consequence of such Lender's
obligations under this Agreement, then, upon demand of such Lender, each
Borrower shall immediately pay to such Lender, from time to time as specified by
such Lender, additional amounts sufficient to compensate such Lender for such
increase, to the extent related to the Loans made to such Borrower. A
certificate of such Lender setting forth in reasonable detail the basis for
determining any such additional amounts payable pursuant to the preceding
sentence shall be submitted by such Lender through the Administrative Agent to
the Company and shall be conclusive in the absence of manifest error.

3.4.     EFFECT ON OBLIGATION TO CONVERT.

         If notice has been given pursuant to subsection 3.1 or 3.2 hereof
requiring the Eurodollar Loans of any Lender to be prepaid or converted, then,
unless and until such Lender notifies the Company that the circumstances giving
rise to such prepayment or conversion no longer apply, the obligation of such
Lender to make or convert to Eurodollar Loans shall be suspended.

                                       37

<PAGE>   55

3.5.     FUNDING LOSSES.

         Each Borrower shall pay to each Lender, upon written request, such
amount or amounts as shall compensate such Lender for any loss or expense
incurred by such Lender (including, without limitation, any loss or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund or maintain its Eurodollar Loans made to such
Borrower) as a result of (i) any payment or prepayment or conversion of a
Eurodollar Loan on a date other than a date which is the last day of an Interest
Period for such Eurodollar Loan or any payment in respect of increased costs to
such Lender, whether pursuant to subsection 3.2 or subsection 3.3 (except when
such payment or prepayment pursuant to subsection 3.2 or subsection 3.3 is
required due to a request or directive which does not have the force of law) or
subsection 6.1 hereof or otherwise or (ii) any failure by such Borrower to
borrow or prepay a Eurodollar Loan or to convert an ABR Loan into a Eurodollar
Loan on the date scheduled for such borrowing, prepayment or conversion. Each
Lender shall furnish the Company with a reasonably detailed statement explaining
the amount of any such loss or expense, which statement shall be conclusive
absent manifest error.

                           SECTION 3A GUARANTY.

3A.1.    GUARANTY OF PAYMENT.

         Subject to subsection 3A.7 below, each of the Guarantors hereby,
jointly and severally, unconditionally guarantees to (a) each Lender, (b) each
Affiliate of a Lender that enters into a Hedging Agreement and (c) the Agents
the prompt payment of the Guaranteed Obligations in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration or otherwise). This
guaranty is a guaranty of payment and not merely of collection and is a
continuing guaranty and shall apply to all Guaranteed Obligations whenever
arising.

3A.2.    OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors hereunder are absolute and
unconditional, irrespective of the value, genuineness, validity, regularity or
enforceability of the Credit Documents or the Hedging Agreements, or any other
agreement or instrument referred to herein, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor. Each Guarantor agrees that this guaranty may be enforced by the
Lenders without the necessity at any time of resorting to or exhausting any
security or collateral and without the necessity at any time of having recourse
to the Notes, the Agreement or any other Credit Documents or any collateral, if
any, hereafter securing the Guaranteed Obligations or otherwise and each
Guarantor hereby waives the right to require the Lenders to proceed against a
Borrower or any other Person (including a co-guarantor) or to require the
Lenders to pursue any other remedy or enforce any other right. Each Guarantor
further agrees that it shall have no right of subrogation, indemnity,
reimbursement or contribution against a Borrower or any other guarantor of the
Guaranteed Obligations for amounts paid under this guaranty until such time as
the Lenders (and any Affiliates of Lenders entering into Hedging Agreements)
have been paid in full, all Commitments under the Agreement have been terminated
and no Person or Governmental Authority shall have any right to request any
return or reimbursement of funds from the Lenders in connection with monies
received under the Agreement. Each Guarantor further agrees that nothing
contained herein shall prevent the Lenders from suing on the Notes, the
Agreement or any other Credit Document or any of the Hedging Agreements or
foreclosing its security interest in or Lien on any collateral, if any, securing
the Guaranteed Obligations or from exercising any other rights available to it
under this Agreement, the Notes, or any other instrument of security, if any,
and the exercise of any of the aforesaid rights and the completion of any
foreclosure proceedings shall not constitute a discharge of any of a Guarantor's
obligations hereunder; it being the purpose and intent of each Guarantor that
its obligations hereunder shall be absolute, independent and unconditional under
any and all circumstances. Neither a Guarantor's obligations under this guaranty
nor any remedy for the enforcement thereof shall be impaired, modified, changed
or released in any manner whatsoever by an impairment, modification, change,
release or limitation of the

                                       38

<PAGE>   56

liability of a Borrower or by reason of the bankruptcy or insolvency of a
Borrower. Each Guarantor waives any and all notice of the creation, renewal,
extension or accrual of any of the Guaranteed Obligations and notice of or proof
of reliance of by an Agent or any Lender upon this guaranty or acceptance of
this guaranty. The Guaranteed Obligations, and any of them, shall conclusively
be deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon this guaranty. All dealings between the
Borrowers and any of the Guarantors, on the one hand, and the Agents and the
Lenders, on the other hand, likewise shall be conclusively presumed to have been
had or consummated in reliance upon this guaranty.

3A.3.    MODIFICATIONS.

         Each Guarantor agrees that (a) all or any part of the security which
hereafter may be held for the Guaranteed Obligations, if any, may be exchanged,
compromised or surrendered from time to time; (b) the Lenders shall not have any
obligation to protect, perfect, secure or insure any such security interests,
liens or encumbrances which hereafter may be held, if any, for the Guaranteed
Obligations or the properties subject thereto; (c) the time or place of payment
of the Guaranteed Obligations may be changed or extended, in whole or in part,
to a time certain or otherwise, and may be renewed or accelerated, in whole or
in part; (d) a Borrower and any other party liable for payment under the
Agreement may be granted indulgences generally; (e) any of the provisions of the
Notes, the Agreement or any other Credit Document may be modified, amended or
waived; (f) any party (including any co-guarantor) liable for the payment
thereof may be granted indulgences or be released; and (g) any deposit balance
for the credit of a Borrower or any other party liable for the payment of the
Guaranteed Obligations or liable upon any security therefor may be released, in
whole or in part, at, before or after the stated, extended or accelerated
maturity of the Guaranteed Obligations, all without notice to or further assent
by such Guarantor, which shall remain bound thereon, notwithstanding any such
exchange, compromise, surrender, extension, renewal, acceleration, modification,
indulgence or release.

3A.4.    WAIVER OF RIGHTS.

         Each Guarantor expressly waives to the fullest extent permitted by
applicable law: (a) notice of acceptance of this guaranty by the Lenders and of
all extensions of credit to a Borrower by the Lenders; (b) presentment and
demand for payment or performance of any of the Guaranteed Obligations; (c)
protest and notice of dishonor or of default (except as specifically required in
the Agreement) with respect to the Guaranteed Obligations or with respect to any
security therefor; (d) notice of the Lenders obtaining, amending, substituting
for, releasing, waiving or modifying any security interest, lien or encumbrance,
if any, hereafter securing the Guaranteed Obligations, or the Lenders
subordinating, compromising, discharging or releasing such security interests,
liens or encumbrances, if any; (e) all other notices to which such Guarantor
might otherwise be entitled in connection with the guaranty evidenced by this
Section 3A; and (f) demand for payment under this guaranty.

3A.5.    REINSTATEMENT.

         The obligations of the Guarantors under this Section 3A shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Guaranteed Obligations is rescinded
or must be otherwise restored by any holder of any of the Guaranteed
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Agents and each Lender on demand for all reasonable, documented costs and
expenses (including, without limitation, reasonable, documented fees of counsel)
incurred by an Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

<PAGE>   57

3A.6.    REMEDIES.

         Each Guarantor agrees that, as between the Guarantors, on the one hand,
and the Agents and the Lenders, on the other hand, the Guaranteed Obligations
may be declared to be forthwith due and payable as provided in subsection 6.1
(and shall be deemed to have become automatically due and payable in the
circumstances provided in subsection 6.1) notwithstanding any stay, injunction
or other prohibition preventing such declaration (or preventing such Guaranteed
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or such Guaranteed
Obligations being deemed to have become automatically due and payable), such
Guaranteed Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors. The Guarantors
acknowledge and agree that their obligations hereunder shall be secured in
accordance with the terms of the Collateral Documents and that the Lenders may
exercise their rights and remedies thereunder in accordance with the terms
thereof.

3A.7.    LIMITATION OF GUARANTY.

         Notwithstanding any provision to the contrary contained herein, to the
extent the obligations of any Guarantor shall be adjudicated to be invalid or
unenforceable for any reason (including, without limitation, because of any
applicable state or federal law relating to fraudulent conveyances or transfers)
then the obligations of such Guarantor hereunder shall be limited to the maximum
amount that is permissible under applicable law (whether federal or state and
including, without limitation, the Federal Bankruptcy Code (as now or
hereinafter in effect)).

3A.8.    RIGHTS OF CONTRIBUTION.

         The Guarantors agree among themselves that, in connection with payments
made hereunder, each Guarantor shall have contribution rights against the other
Guarantors as permitted under applicable law. Such contribution rights shall be
subordinate and subject in right of payment to the obligations of the Guarantors
under the Credit Documents and no Guarantor shall exercise such rights of
contribution until all Guaranteed Obligations have been paid in full and the
Commitments terminated.

         Proceeds in accordance with the terms of subsection 2.6(b)(ii)(C). All

Administrative Agent in the event any Credit Party discovers or determines that
any computer application that is material to its or any of its Subsidiaries'

expected to have a Material Adverse Effect.

in accordance with subsection 1.6 and (ii) the Letters of Credit solely for the
purposes set forth in subsection 1.6.

business hours, each Credit Party will permit representatives appointed by the
Administrative Agent, including, without limitation, independent accountants,
agents, attorneys and appraisers, to visit and inspect such Credit Party's
property, including its books and records, its accounts receivable and
inventory, its facilities and its other business assets, and to make photocopies
or photographs thereof and to write down and record any information such
representative obtains and shall permit the Administrative Agent or its
representatives to investigate and verify the accuracy of information provided
to the Lenders, and to discuss all such matters with the executive officers,
pertinent employees and representatives of the Credit Parties; provided,
however, that so long as no Event of Default shall have occurred and be
continuing, (i) no verification of accuracy of information shall include
contacting the account debtors under any

provisions of subsection 9.16.

         (j) Additional Credit Parties. At the time any Person becomes a
Domestic Subsidiary (other than a Receivables Financing SPC or a Preferred Stock
SPC or as otherwise agreed to by the Administrative Agent) or becomes a
guarantor with respect to any other Indebtedness of the Company, the Company
shall so notify the Administrative Agent and promptly thereafter (but in any
event within 30 days after the date thereof) shall (a) cause such Person to
execute a Guarantor Joinder Agreement in substantially the same form as Exhibit
E, (b) cause such Person to execute counterparts of, or a joinder in, the Pledge
Agreement and the Security Agreement, (c) cause all of the capital stock of such
Person to be delivered to the Collateral Agent (together with undated stock
powers, if applicable, signed in blank) and pledged to the Collateral Agent, (d)
cause all of the Capital Stock of the Domestic Subsidiaries of such Person and
65% of the voting Capital Stock and all non-voting capital stock of its First
Tier Foreign Subsidiaries to be delivered to the Collateral Agent (together with
undated stock powers, if applicable, signed in blank) and pledged to the
Collateral Agent, and (e) deliver, or cause such Person to deliver, such other
documentation as the Collateral Agent may reasonably request in connection with
the foregoing, including, without limitation, certified resolutions and other
organizational and authorizing documents of such Person, favorable opinions of
counsel to such Person (which shall cover, among other things, the legality,
validity, binding effect and enforceability of the documentation referred to
above) and appropriate UCC-1 financing statements, all in form, content and
scope reasonably satisfactory to the Collateral Agent.

         (k)      Further Assurances.  Each Credit Party will:

         ownership interest in real property (other than an Excluded Asset) or

         is using it best efforts to deliver such documents, execute,
         acknowledge, record or register and deliver to the Collateral Agent (in
         a form reasonably satisfactory to the Agents) such mortgages, deeds of
         trust or other real estate security documents as may be required
         validly to create and perfect and ensure the priority and
         enforceability of a Lien upon such interest in favor of the Collateral
         Agent for the benefit of the Lenders and each other beneficiary of the
         security interests granted in the Pledge Agreement and the Security
         Agreement (to the extent such beneficiary has a legal or contractual
         right to the benefit of such Lien).

                  (ii) To the extent requested by the Administrative Agent, at
         its expense, within 60 days after the Third Amendment Effective Date as
         to each property subject to a Mortgage, deliver to the Collateral Agent
         such additional certificates, legal opinions, surveys, policies of
         title insurance, loss payee endorsements and other supporting documents
         related to the Mortgages, and take such actions (specifically including
         slipsheeting pages to the Mortgages to effect modifications suggested
         by local counsel and providing for the recording of the Mortgages in
         the appropriate recording offices) with respect to perfecting the Liens
         granted to the Collateral Agent pursuant to the Mortgages, in each case
         as the Administrative Agent may reasonably request. In connection with
         the Mortgages, the parties hereto agree that the Mortgages may be
         slipsheeted following the Third Amendment Effective Date to effect
         modifications suggested by local counsel to ensure proper recording of

6.2.     CONVERSION AND REDENOMINATION CERTAIN LOANS; PURCHASE OF RISK
         PARTICIPATIONS.

         (a) Conversion and Redenomination of Certain Loans. Notwithstanding
anything herein to the contrary, upon a termination of the Commitments following
the occurrence of an Event of Default (a "Commitment Termination Event"), all
outstanding Loans denominated in a Foreign Currency or bearing interest at a
rate other than the ABR shall be redenominated and/or converted into ABR Loans
in U.S. Dollars on and with effect from the soonest practicable date following
the Commitment Termination Event as determined by the Administrative Agent (the
"Conversion Date"). The Borrowers hereby agree to pay to the Administrative
Agent, for the pro rata benefit of the Lenders, on the Conversion Date any
amounts owing pursuant to subsection 3.5 as a result of any such conversion
occurring prior to the end of an Interest Period. The Administrative Agent will
promptly notify the Company and the Lenders of any such redenomination and
conversion following a Commitment Termination Event.

         (b) Purchase of Risk Participations. Each Revolving Credit Lender
hereby agrees that it shall forthwith purchase, as of the Conversion Date (but
adjusted for any payments received from a Borrower on or after such date and
prior to such purchase), from the other Revolving Credit Lenders such
Participation Interests in the outstanding Revolving Credit Loans (whether or
not such Loans have been redenominated or converted pursuant to subsection
6.2(a)) as shall be necessary to cause each such Revolving Credit Lender to
share in all Revolving Credit Loans ratably based upon its Commitment Percentage
with respect to Participation Interests in all Revolving Credit Loans
(determined before giving effect to any termination of the Commitments),
provided that (A) all interest payable on a Revolving Credit Loan shall be for
the account of the Revolving Credit Lender that originally made such Loan until
the date as of which the respective Participation Interest is purchased and (B)
if any purchase of a Participation Interest required to be made pursuant to this
sentence is not made on the Conversion Date, then at the time such purchase is
actually made the purchasing Lender shall be required to pay to the selling
Lender, to the extent not paid to such selling Lender by the applicable Borrower
in accordance with the terms of this Agreement, interest on the principal amount
of the Participation Interest purchased for each day from and including the day
upon which such purchase of the Participation Interest would otherwise have
occurred to but excluding the date of actual payment for the purchase of such
Participation Interest, at the rate equal to the Federal Funds Effective Rate
(as defined in the definition of "ABR").

                             SECTION 7. DEFINITIONS.

         As used in this Agreement, the following terms shall have the following
meanings (and including the plural as well as the singular):

         "ABR": for any day, a rate per annum (rounded upwards, if necessary, to
the next 1/16 of 1%) equal to the greater of (a) the Prime Rate in effect on
such day and (b) 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 established from time to time by the Administrative Agent as its prime
rate in effect at its principal office in Charlotte, North Carolina (the Prime
Rate not being intended to be the lowest rate of interest charged by Bank of
America, N.A. in connection with extensions of credit to debtors); 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,

                                       56

<PAGE>   74

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 Federal Funds Effective Rate 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) of the first sentence of this definition until the
circumstances giving rise to such inability no longer exist. Any change in the
ABR due to a change in the Prime 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 or the Federal Funds Effective Rate, respectively.

         "ABR Loans": Loans denominated in U.S. Dollars the rate of interest
applicable to which is based upon the ABR.

         "Acceptance Fee": an amount equal to the product of (a) the Applicable
Margin for Revolving Eurodollar Loans and Bankers' Acceptances; (b) the
aggregate Face Amount of Bankers' Acceptances accepted by a Canadian Lender on
the date of the requested Bankers' Acceptances; and (c) a fraction (i) the
numerator of which is the term to maturity of such Bankers' Acceptances, and
(ii) the denominator of which is 365 days.

         "Acquisition": the acquisition by the Company and/or any of its
Subsidiaries of the Capital Stock of BetzDearborn pursuant to the Merger
Agreement.

         "Additional Credit Party": each Person that becomes a Guarantor after
the Closing Date, as provided in subsection 5.1(j).

         "Administrative Agent": Bank of America, N.A., formerly known as
NationsBank, N.A. or any successor.

         "Affiliate": as to any specified 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 specified Person means the power, directly or indirectly, either
to (a) vote 20% or more of the securities having ordinary voting power for the
election of directors of such Person or (b) direct or cause the direction of the
management and policies of such Person whether through the ownership of voting
securities, by contract or otherwise.

         "Agents":  the Administrative Agent and the Canadian Administrative
Agent.

         "Agreement": this Agreement, as amended, supplemented or modified from
time to time.

         "Applicable BA Discount Rate": (i) with respect to any Canadian Lender
named on Schedule I to the Bank Act (Canada), as applicable to a Bankers'
Acceptance being purchased by such Lender on any day, the respective percentage
discount rate per annum for a Canadian Dollar bankers' acceptance for the term
and face amount comparable to the term and face amount of such Bankers'
Acceptance that appears on the Reuters Screen CDOR Page as of 10:00 A.M.
(Toronto, Ontario time) on the date of determination as reported by the Canadian
Administrative Agent; provided, however, that if no rate appears on the Reuters
Screen CDOR Page as contemplated then the CDOR Rate on any date shall be
calculated as the arithmetic mean of the rates for the applicable term referred
to above applicable to Canadian Dollar bankers' acceptances quoted by Canadian
chartered banks named on Schedule I to the Bank Act (Canada) as of 10:00 a.m.
(Toronto, Ontario time) on such applicable date and (ii) with respect to any
Canadian Lender named on Schedule II to the Bank Act (Canada), as applicable to
a Bankers' Acceptance being purchased by such Lender on any day, the lesser of
(x) the average (as determined by

                                       57

<PAGE>   75

the Canadian Administrative Agent) of the respective percentage discount rates
(expressed to two decimal places and rounded upward, if necessary, to the
nearest 1/100th of 1%) quoted to the Canadian Administrative Agent by each of
Bank of America Canada and Citibank Canada (each a "Schedule II Reference Bank")
as the percentage discount rate at which such Schedule II Reference Bank would,
in accordance with its normal practices, at or about 10:00 A.M. (Toronto time)
on such day, be prepared to purchase bankers' acceptances accepted by such
Schedule II Reference Bank having a term and a face amount comparable to the
term and face amount of such Bankers' Acceptance and (y) the rate that is 10
basis points per annum in excess of the rate determined pursuant to clause (i)
of this definition in connection with the relevant issuance of Bankers'
Acceptances.

         "Applicable Margin": with respect to (a) Eurodollar Loans and Bankers'
Acceptances, (b) Base Rate Loans and (c) the Facility Fees, the rate per annum
applicable on any date determined based upon the ratings applicable on such date
to the Company's long-term senior secured bank rating (the "Index Debt") by
Moody's and S&P as follows:

For purposes of the foregoing, (i) if neither Moody's nor S&P shall have in
effect a rating for the Index Debt (other than by reason of the circumstances
referred to in the last sentence of this definition), then both such rating
agencies will be deemed to have established the ratings referred to in clause
(8) above for the Index Debt; (ii) if only one of Moody's or S&P shall have in
effect a rating for the Index Debt, the Company and the Lenders will negotiate
in good faith to agree upon another rating agency to be substituted by an
amendment to this Agreement for the rating agency which shall not have a rating
in effect, and in the absence of such amendment the Applicable Margin will be
determined by reference to the available rating; (iii) if the ratings
established by Moody's and S&P shall indicate different clauses

                                       58

<PAGE>   76

specified above, the Applicable Margin shall be determined by reference to the
numerically lower clause, unless such numerically lower clause is more than one
numeral lower than the clause indicated by the other rating, in which case the
clause which is one number lower than such higher numbered clause shall apply
(thus, by way of example, if the Company's Index Debt is rated BBB by S&P and
Ba1 by Moody's, the clauses indicated are (2) and (5), respectively, resulting
in the Applicable Margin being determined by reference to clause (4), which
clause is one number lower than such higher numbered clause); provided, however,
that the Applicable Margin shall be determined by reference to clause (8) if the
Company's Index Debt is rated worse than BB by S&P or worse than Ba2 by Moody's;
(iv) if any rating established by Moody's or S&P shall be changed (other than as
a result of a change in the rating system of either Moody's or S&P) such change
shall be effective as of the date on which such change is first announced by the
rating agency making such change; and (v) notwithstanding anything in this
definition of "Applicable Margin" to the contrary, (a) from the Closing Date
until the Tranche B Term Loan has been fully repaid, the Applicable Margin will
be determined by reference to clause (8) above and (b) in no event shall (1) the
Applicable Margin for Revolving Eurodollar Loans, and Bankers' Acceptances be
less than 1.75%, (2) the Applicable Margin for Tranche A Eurodollar Loans be
less than 2.25%, (3) the Applicable Margin for Tranche D Eurodollar Loans be
less than 2.75%, (4) the Applicable Margin for Revolving Base Rate Loans and
Tranche A Base Rate Loans be less than 1.25%, (5) the Applicable Margin for
Tranche D Base Rate Loans be less than 1.75% or (6) the Applicable Margin for
Facility Fees be less than 0.50%, in each case prior to the date on which
financial statements are delivered in respect of the second full fiscal quarter
of the Company following the Third Amendment Effective Date. Each change in the
Applicable Margin shall apply during the period commencing on the effective date
of such change and ending on the date immediately preceding the effective date
of the next such change. If the rating system of either Moody's or S&P shall
change prior to the Termination Date, the Company and the Lenders shall
negotiate in good faith to amend the references to specific ratings in this
definition to reflect such changed rating system. If both Moody's and S&P shall
cease to be in the business of rating corporate debt obligations, the Company
and the Lenders shall negotiate in good faith to agree upon a substitute rating
agency and to amend the references to specific ratings in this definition to
reflect the ratings used by such substitute rating agency.

         "Applicant Borrower":  as defined in subsection 2.13.

         "Asset Disposition": the disposition of any or all of the assets
(including without limitation the Capital Stock of a Subsidiary) of the Company
or any of its Subsidiaries whether by sale, lease, transfer or otherwise

"Asset Disposition" shall not include (i) the sale of inventory in the ordinary
course of business, (ii) the sale or disposition of machinery and equipment no
longer used or useful in the conduct of such Person's business or (iii) any
Equity Issuance by the Company or (iv) intercompany transfers from a Credit
Party or a wholly-owned Subsidiary of a Credit Party to a Credit Party.

         "Assignee":  as defined in subsection 9.6(c).

         "Attributed Principal Amount": on any day, with respect to any
Permitted Receivables Financing entered into by the Company or any of its
Consolidated Subsidiaries, the aggregate amount (with respect to any such
transaction, the "Invested Amount") paid to, or borrowed by, such Person as of
such date under such Permitted Receivables Financing, minus the aggregate amount
received by the applicable Receivables Financier (as defined in the definition
of "Permitted Receivables Financing") and applied to the reduction of the
Invested Amount under such Permitted Receivables Financing.

to be purchased on any day under subsection 2.18(a), in an amount (rounded to
the nearest whole Canadian cent, and with one-half of one Canadian cent being
rounded up) calculated on such day by dividing:

         (a)      the Face Amount of such Bankers' Acceptance; by

         (b)      the sum of one plus the product of:

                  (i) the Applicable BA Discount Rate (expressed as a decimal)
         applicable to such Bankers' Acceptance; and

                  (ii) a fraction, the numerator of which is the number of days
         remaining in the term of such Bankers' Acceptance and the denominator
         of which is 365;

         with such product being rounded up or down to the fifth decimal place

Committed Amount.

         "BACAN U.S. Base Rate": The higher of (a) the Federal Funds Effective
Rate (as defined in the definition of "ABR") and (b) the BACAN U.S. Prime Rate;
provided, however, that if, in the reasonable judgment of the Canadian

Credit Documents, together with such other powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary elsewhere in this
Agreement, no Agent shall have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and

                                       79

<PAGE>   97

obligations or liabilities shall be read into this Agreement or any other
Credit Document or otherwise exist against an Agent.

8.2.     DELEGATION OF DUTIES.

         Each Agent may execute any of its duties under this Agreement and the
other Credit Documents by or through agents or attorneys-in-fact and shall be
entitled to advice of counsel concerning all matters pertaining to such duties.
No Agent shall be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

8.3.     EXCULPATORY PROVISIONS.

         Neither an 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 Credit 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 Company, any other Credit Party or any officer thereof contained in this
Agreement or any other Credit Document or in any certificate, report, statement
or other document referred to or provided for in, or received by such Agent
under or in connection with, this Agreement or any other Credit Document or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or the other Credit Documents or for any failure of the
Company or any other Credit Party to perform its obligations hereunder or
thereunder. No Agent shall 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 Credit Document, or
to inspect the properties, books or records of the Credit Parties.

8.4.     RELIANCE BY AGENTS.

         Each Agent shall be entitled to rely, and shall be fully protected in
relying, upon any Credit Document, writing, resolution, notice, consent,
certificate, affidavit, letter, telecopy, telex or teletype message, statement,
order or other document or conversation reasonably 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 Credit Parties), independent accountants and other
experts selected by such Agent. The Agents 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. Each Agent shall be fully justified in failing or refusing
to take any action under this Agreement or any other Credit 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
Lenders against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. Each Agent shall in all
cases be fully protected in acting, or in refraining from acting, under this
Agreement and the other Credit Documents in accordance with a request of the

pursuant thereto shall be binding upon all the Lenders and all future holders of

occurrence of any Default or Event of Default hereunder unless such 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 of default". In the event that an Agent receives such a notice, such
Agent shall give notice thereof to the Lenders. The Administrative Agent shall
take such action with respect to such Default or Event of Default 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 or Event of Default as it shall
deem advisable in the best interests of the Lenders.

officers, directors, employees, agents, attorneys-in-fact or affiliates has made
any representations or warranties to it and that no act by an Agent hereinafter
taken, including any review of the affairs of the Credit Parties, shall be
deemed to constitute any representation or warranty by such Agent to any Lender.
Each Lender represents to the Agents that it has, independently and without
reliance upon an 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 Credit Parties and made its own decision
to make its Loans hereunder and enter into this Agreement and the other Credit
Documents. Each Lender also represents that it will, independently and without
reliance upon an 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 Credit 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 Credit Parties. Except
for notices, reports and other documents expressly required to be furnished to
the Lenders by an Agent hereunder, no Agent shall 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 the Credit Parties which may come
into the possession of an Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates.

8.7.     INDEMNIFICATION.

         The Lenders agree to indemnify each Agent in its capacity as such (to
the extent not reimbursed by the Company or another Credit Party and without
limiting the obligation of the Company or another Credit Party to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought under this subsection (or, if
indemnification is sought after the date upon which the Commitments shall have
terminated and the Loans shall have been paid in full, ratably in accordance
with their Commitment 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 Notes) be imposed on, incurred by or asserted
against such Agent in any way relating to or arising out of this Agreement, any
of the other Credit 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 such 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 to the extent resulting from
such Agent's gross negligence or willful misconduct. The agreements in this
subsection shall survive the payment of the Notes and all other amounts payable
hereunder or under the other Credit Documents.

8.8.     AGENT IN ITS INDIVIDUAL CAPACITY.

         An Agent and its affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Credit Parties as though such
Agent were not an Agent hereunder and under the other Credit Documents. With
respect to its Loans made or renewed by it and any Note issued to it, each Agent
shall have the same rights and powers under this Agreement and the Notes as any
Lender and may exercise the same as though it were not an Agent, and the terms
"Lender" and "Lenders" shall include such Agent in its individual capacity.

8.9.     SUCCESSOR AGENT.

         An Agent may resign as Agent upon 10 days' notice to the Lenders. If an
Agent shall resign as Agent under this Agreement and the other Credit Documents,
then the Required Lenders shall appoint from among the Lenders a successor agent
for the Lenders, which successor agent shall, so long as no

                                       81

<PAGE>   99

Event of Default exists, be approved by the Company (which approval shall not
be unreasonably withheld), whereupon such successor agent shall succeed to
the rights, powers and duties of the Administrative Agent, Canadian
Administrative Agent or Collateral Agent, as applicable, and the term
"Administrative Agent", "Canadian Administrative Agent" or "Collateral Agent",
as the case may be, shall mean such successor agent effective upon such
appointment and approval, and the former Agent's rights, powers and duties as
Agent shall be terminated, without any other or further act or deed on the part
of such former Agent or any of the parties to this Agreement or any of the other
Credit Documents or any holders of the Notes. After any retiring Agent's
resignation as 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 Agent
under this Agreement and the other Credit Documents.

8.10.    TRANCHE D ARRANGER.

         The parties acknowledge and agree that the Tranche D Arranger (a) shall
be credited as and may publicize that it is the sole lead arranger and book
manager of the Tranche D Term Loan, (b) shall not, by reason of its designation
as such or any of the provisions hereof relating to the Tranche D Arranger or
any action taken or omitted by it (in any capacity) in respect of this Agreement
or the financing contemplated hereby, have any power, duty, responsibility or
liability whatsoever under this Agreement and (c) shall nevertheless be entitled
to all of the immunities, indemnities and benefits granted to it or to any Agent
or Co-Agent herein, including each of the immunities, indemnities and benefits
of the Administrative Agent under subsections 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8
and 8.9. In addition to the requirements set forth in Section 9.1, this

         The Company agrees (a) to pay or reimburse each Agent and the Tranche D

amendment, supplement or modification to, this Agreement, the Notes and the

Tranche D Arranger for all its reasonable costs and expenses incurred in
connection with the enforcement or preservation of any rights under this
Agreement, the Notes and any such other documents, including, without
limitation, the reasonable fees and disbursements of counsel to the
Administrative Agent, counsel to the Tranche D Arranger and counsel to the
several Lenders (including, without duplication, the allocated costs of in-house
counsel to any Lender), and (c) to pay, indemnify, and hold each Lender and each
Agent and the Tranche D Arranger harmless from, any and all recording and filing
fees and any and all liabilities with respect to, or resulting from any delay in
paying, stamp, excise and other 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 Notes and any such other documents, and (d)
to pay, indemnify, and hold each Lender and each Agent and the Tranche D
Arranger (each, an "indemnified person") harmless from and against any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever with
respect to the execution, delivery, enforcement, performance and administration
of this Agreement, the Notes, the LOC Documents, the use of proceeds of the

"indemnified liabilities"); provided that the Company shall have no obligation
hereunder to any Agent or any Lender with respect to indemnified liabilities
arising from (i) the gross negligence or willful misconduct of such indemnified
person or (ii) legal proceedings commenced against such indemnified person 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.
The agreements in this subsection shall survive repayment of the Notes, the LOC
Obligations and all other amounts payable hereunder or under the other Credit
Documents.

9.6.     SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS.

         (a) This Agreement shall be binding upon and inure to the benefit of
the Credit Parties, the Lenders, the Agents, all future holders of the Notes and
their respective successors and assigns, except that no Credit Party may assign
or transfer any of its rights or obligations under this Agreement without the
prior written consent of each Lender.

         (b) Any Lender may, in the ordinary course of its commercial banking
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 Commitment of such
Lender, any Participation Interest of such Lender or any other interest of such
Lender hereunder, under the Notes or under any other Credit Document. In the
event of any such sale by

                                       85

<PAGE>   103

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 Notes, and the Credit Parties and the
Agents shall continue to deal solely and directly with such Lender in connection
with such Lender's rights and obligations under this Agreement and the Notes.
The Credit Parties agree that if amounts outstanding under this Agreement, the
Notes or any other Credit Document 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 be deemed to have the right of setoff in respect
of its participating interest in amounts owing under this Agreement, any Note or
any other Credit Document to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, any Note or any other Credit Document, 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 9.7(a) as
fully as if it were a Lender hereunder.

         (c) Any Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time and from time to
time assign to any Lender or any affiliate thereof or a Control Investment
Affiliate or, with the consent of (x) so long as no Event of Default exists, the
Company and (y) the Administrative Agent and in the case of an assignment of the
Tranche D Term Loan, the Tranche D Arranger (which in each case shall not be
unreasonably withheld), to any other Person (an "Assignee") all or any part of
its rights and obligations under this Agreement, the Notes and the other Credit
Documents pursuant to an Assignment and Acceptance, substantially in the form of
Exhibit 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
and the Administrative Agent, and in the case of an assignment of the Tranche D
Term Loan, the Tranche D Arranger) and delivered to the Administrative Agent for
its acceptance and recording in the Register; provided, however, that the amount
of the Commitment (if any) of the assigning Lender being assigned pursuant to
each such assignment (determined as of the date of the Assignment and Acceptance
with respect to such assignment) shall in no event be less than the lesser of
(i) $1,000,000 and (ii) with respect to each assigning Lender, the amount of
such Lender's Commitment, and shall be in an integral multiple of $1,000,000
(or, if less, with respect to each assigning Lender, the amount of such Lender's
Commitment); provided, further, that, in the case of any proposed assignment
pursuant to this subsection 9.6(c) to an Assignee which is not a Lender or any
affiliate of a Lender, if (A) no Event of Default exists, (B) the Company
objects to such proposed Assignee and (C) the Company no later than 5 Business
Days after receipt of notice by the Company of such proposed Assignee, proposes
an alternative Assignee acceptable to the Administrative Agent and willing to
consummate such assignment with the assigning Lender within 30 days from the
date thereof and on the same terms and conditions as such assigning Lender's
proposed Assignee, such assigning Lender shall not have the right to effect such
proposed assignment to its proposed Assignee. 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 Commitment 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).

         (d) The Administrative Agent shall maintain at its address referred to
in subsection 9.2 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 Credit Parties, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register as
the owner of the Loan recorded therein for all

                                       86

<PAGE>   104

purposes of this Agreement. The Register shall be available for inspection
by the Company, the Tranche D Arranger or any Lender at any reasonable time
and from time to time upon reasonable prior notice.

         (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 a Control Investment Affiliate or an affiliate thereof, by the
Company and the Administrative Agent), together with payment by the assigning
Lender to the Administrative Agent of a registration and processing fee of
$3,500, 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 Lenders and the Company on behalf of the Borrower. On or
prior to the effective date of any such Assignment and Acceptance, each
Borrower, at its own expense, shall execute and deliver to the Administrative
Agent a new Note or Notes to the order of such Assignee. Such new Notes shall be
dated the Closing Date and shall otherwise be in the form of the Notes replaced
thereby.

         (f) Each Credit Party authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee
any and all financial information in such Lender's possession concerning such
Credit Party and its affiliates which has been delivered to such Lender by or on
behalf of the Company pursuant to this Agreement or which has been delivered to
such Lender by or on behalf of the Company in connection with such Lender's
credit evaluation of the Company and its affiliates prior to becoming a party to
this Agreement.

         (g) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement to secure obligations of
such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this subsection 9.6 shall not apply to any such pledge
or assignment of a security interest; provided that no such pledge or assignment
of a security interest shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

9.7.     ADJUSTMENTS; SET-OFF.

         (a) If any Lender (a "benefited Lender") shall at any time receive any
payment of all or part of its Loans or Participation Interests, or interest
thereon, 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 subsections 6(f) or (g), 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 Loans or Participation Interests, or interest
thereon, such benefited Lender shall purchase for cash from the other Lenders a
participating interest in such portion of each such other Lender's Loan, or
shall provide such other Lenders with the benefits of any such collateral, or
the proceeds thereof, as shall be necessary to cause such benefited 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 benefited 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, each Lender shall have the right, without prior notice to any Credit Party,
any such notice being expressly waived by each Credit Party to the extent
permitted by applicable law, upon any amount becoming due and payable by such
Credit Party hereunder, under the Notes or under any other Credit Document
(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 affiliate, branch or agency thereof to or for the
credit or the account of such Credit Party. Each Lender agrees promptly to

                                       87

<PAGE>   105

notify the Company on behalf of the respective Credit Party 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.

9.8.     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.

9.9.     ADJUSTMENTS FOR CHANGES IN GAAP.

         In the event that a change in GAAP affects the terms of the covenants
contained in subsection 5.2(d) hereof (including the related defined terms used
therein), the Company and the Required Lenders shall negotiate in good faith
such amendments to such covenant and related definitions as are necessary to
reflect such changes in GAAP and as are otherwise reasonably satisfactory to the
Company and the Required Lenders.

9.10.    SEVERABILITY; SECTION HEADINGS.

         (a) 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.

         (b) The Section and subsection headings and the Table of Contents
contained herein are for convenience of reference only and shall not affect the
construction hereof.

STATE OF NORTH CAROLINA.

         (a) submits for itself and its property in any legal action or

         (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

         (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 Credit Party at
its address set forth in subsection 9.2 or at such other address of which the
Administrative Agent 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.

         The Lenders hereby agree that the Administrative Agent, on behalf of

("Prudential"), as the holder of the Guaranteed ESOT Notes Due June 19, 2009 of
The BetzDearborn Inc. Employee Stock Ownership and 401(k) Plan currently
outstanding in the aggregate principal amount of $93,500,000, which

sharing among the Lenders and Prudential of any proceeds of the Collateral or
the guarantees under Section 3A.

9.18.    BINDING EFFECT; AMENDMENT AND RESTATEMENT OF EXISTING CREDIT
AGREEMENT; FURTHER ASSURANCES.

         This Agreement shall become effective at such time, on or after the
Restatement Effective Date, that the conditions precedent set forth in
subsection 4.1 have been satisfied and when it shall have been executed by each
Credit Party and the Agents, and the Administrative Agent shall have received
copies hereof (telefaxed or otherwise) which, when taken together, bear the
signatures of each Lender (including the Issuing Lender), and thereafter this
Agreement shall be binding upon and inure to the benefit of each Credit Party,
each Lender (including the Issuing Lender) and the Agents, together with their
respective successors and assigns. The Credit Parties and the Lenders (including
the Issuing Lender) party to the Existing Credit Agreement each hereby agrees
that, at such time as this Agreement shall have become effective pursuant to the
terms of the immediately preceding sentence, the Existing Credit Agreement
automatically shall be deemed amended and restated in its entirety by this
Agreement, and all obligations and commitments outstanding under the Existing
Credit Agreement shall be governed by the terms of this Agreement (as such
obligations or commitments may be modified or amended hereunder) and (ii) all of
the promissory notes executed by the Borrowers in connection with the Existing
Credit Agreement automatically shall be substituted and replaced by the amended
and restated promissory notes executed in connection with this Agreement, and
the Lenders agree to promptly return such prior notes to the Company. The Credit
Parties further agree, upon the request of the Administrative Agent and/or the
Required Lenders, to promptly take such actions, as reasonably requested, as are
appropriate to carry out the intent of this Agreement and the other Credit
Documents, including, but not limited to, such actions as are reasonably
necessary to ensure that the Lenders have a perfected security interest in any
and all collateral securing the Guaranteed Obligations, subject to no Liens
other than Permitted Liens.

9.19.    JUDGMENT CURRENCY.

         (a) If for the purposes of obtaining judgment in any court it is
necessary to convert all or any part of the Indebtedness or any other amount due
to the Lenders hereunder or under any security in respect of the Credit Parties'
obligations hereunder in any currency (the "Original Currency") into another
currency (the "Other Currency") each Credit Party to the fullest extent that it
may effectively do so, agrees that the rate of exchange used shall be that at
which, in accordance with normal banking procedures, the Administrative Agent
could purchase the Original Currency with the Other Currency at its principal
offices in Charlotte, North Carolina on the day (an "Administrative Agent's
Business Day") on which the Administrative Agent is open for the transaction of
its banking business at such offices

                                       90

immediately preceding the day on which any such judgment, or any relevant part
thereof, is paid or otherwise satisfied.

         (b) The obligation of each Credit Party in respect of any sum due in
the Original Currency from it to the Lenders hereunder or under any security in
respect of the Credit Parties' obligation hereunder shall, notwithstanding any
judgment in any Other Currency, be discharged only to the extent that on the
Administrative Agent's Business Day following receipt by the Agents of any sum
adjudged to be so due in such Other Currency or of any other sum in any Other
Currency the Agents may, in accordance with their normal banking procedures,
purchase the Original Currency with such Other Currency. If the amount of the
Original Currency so purchased is less than the sum originally due to the
Lenders in the Original Currency, the Credit Parties shall, as a separate
obligation and notwithstanding any such judgment, indemnify the Agents against
such loss, and if the amount of the Original Currency so purchased exceeds the
sum originally due to the Lenders, the Agents shall remit such excess to the
Credit Parties.

9.20.    FIRST AMENDMENT TO PLEDGE AGREEMENT.

         The Required Lenders hereby consent to the amendment of the Pledge
Agreement (as in existence on the Closing Date) effected by the First Amendment

parties thereto substantially in the form of Exhibit I.
