Item 5. Other Events.

        On October 15, 1998, Hercules Incorporated, a Delaware corporation,
merged with BetzDearborn, Inc. In order to pay the merger consideration,
Hercules borrowed $3.65 billion under a credit facility which was syndicated by
NationsBank, N.A. This Credit Agreement, dated October 15, 1998, was previously
filed as an exhibit to Hercules Current Report on Form 8-K dated October 15,
1998.

        On April 19, 1999, upon Hercules' receipt of approval by all lenders
thereunder, the Credit Agreement was amended and restated to effect changes,
including the following:

        (1)     Hercules can now borrow in Euros, as well as United States of
                America dollars, and certain outstanding borrowings were
                converted to indebtedness denominated in Euros.

        (2)     Hercules' Canadian subsidiary, BetzDearborn Canada, Inc., can
                borrow up to U.S. $100 million from select lenders in Canada in
                Canadian dollars.

        (3)     Hercules has greater flexibility to make corporate changes
                within the Hercules family of entities without the need to
                obtain consent from the lenders under the Credit Agreement.

        The Amended and Restated Credit Agreement, dated April 19, 1999, is
attached as an exhibit to this Current Report on Form 8-K and is incorporated by
reference herein.

and authority, and the legal right, to own and operate its property, to lease
the property it operates as lessee and to conduct the business in which it is
currently engaged and (ii) is duly qualified as a foreign entity and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of property or the conduct of its business requires such
qualification, other than in such jurisdictions where the failure to be so

         (a) The consolidated balance sheet of the Company and its Consolidated

         (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.

         1.3. VALIDITY OF DOCUMENTS.

         (a) This Agreement constitutes, and the other Credit Documents when
duly executed and delivered by each Credit Party that is a party thereto in
accordance with this Agreement will constitute, legal, valid and binding
obligations of each Credit Party, each enforceable in accordance with its terms
except as the enforceability of such Credit Document may be limited (x) by
general principles of equity and conflicts of laws or (y) by bankruptcy,
reorganization, insolvency, moratorium or other laws of general application
relating to or affecting the enforcement, of creditors' rights. Neither the
execution, delivery or performance of this Agreement or the other Credit
Documents, nor compliance with the terms and provisions hereof and thereof, will
(i) conflict with, or result in a breach of any provisions of, any Requirement
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.

         (b) No consent or authorization of, filing with, notice to or other
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 Material 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.




                                       3

         1.6. USE OF PROCEEDS.

         The proceeds of the Loans shall be used (a) to fund the Acquisition
(including, without limitation, through loans, advances or equity contributions
made to Subsidiaries of the Company) and (b) for working capital, capital
expenditures, repayment of Indebtedness of the Company, BetzDearborn and their
Subsidiaries and other general corporate purposes. 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.

         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 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 



                                       4
<PAGE>   10


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 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. MATERIAL SUBSIDIARIES.

         Set forth on Schedule II is a complete and accurate list of all
Material Subsidiaries of the Company. Information on Schedule II includes
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 Material Subsidiaries is validly issued, fully paid
and 



                                       5
<PAGE>   11



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 Material 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 Material
         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 Material 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 Material 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
         Material Subsidiaries in connection with the Real Properties or
         otherwise in connection with the 



                                       6
<PAGE>   12


         Businesses, in violation of, or in amounts or in a manner that could
         give rise to liability under, Environmental Laws.

                  (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 and, after consummation of the transactions
contemplated by this Agreement (including without limitation the Acquisition),
will be 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 Material 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.



                                       7
<PAGE>   13



         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.

that in no event shall the aggregate Dollar Amount with respect to principal of
all Canadian Revolving Loans plus the Face Amount of all Bankers' Acceptances at

         2.2. NOTES EVIDENCING REVOLVING CREDIT LOANS.

         The Revolving Credit Loans made by each Lender shall be evidenced by
promissory notes of the applicable Borrowers, each substantially in the form of
Exhibit A with respect to a Borrower that is the Company or a Designated
Borrower (each, as amended, modified, restated, supplemented, extended, renewed

another Type, the date and amount of each payment or prepayment of principal
thereof and, in the case of Eurodollar Loans, the length of each Interest Period
with respect thereto, on a schedule annexed to and constituting a part of its
Note and any such recordation shall constitute prima facie evidence of the
accuracy of the information so recorded; provided, however, that the failure to

the liability of a Borrower hereunder or under any Note. Each Note shall (a) be
dated the Closing Date and (b) provide for the payment of principal and interest
in accordance with the terms of this Agreement.

         2.3. PROCEDURE FOR REVOLVING CREDIT BORROWING.

         (a) U.S. Revolving Loans and Multicurrency Revolving Loans. A Borrower
may borrow under the U.S. Revolving Committed Amount or the Multicurrency

provided that the Company (on behalf of such Borrower) shall give the
Administrative Agent irrevocable notice (which notice must be received by the
Administrative Agent prior to 11:00 A.M., Charlotte, North Carolina time, (a)
three Business Days prior to the requested Borrowing Date, if all or any part of
the requested Revolving Credit Loans are to be initially Eurodollar Loans or (b)
one Business Day prior to the requested Borrowing Date, otherwise),
substantially in the form of Exhibit F, on behalf of the respective Borrower,
specifying (i) the Revolving Committed Amount to be borrowed under (i.e., the
U.S. Revolving Committed Amount or the Multicurrency Revolving Committed

be in an amount equal to (x) in the case of Base Rate Loans or Eurodollar Loans
denominated in U.S. Dollars, $5,000,000 or a whole multiple of $1,000,000 in
excess thereof (or, with respect to Base Rate Loans only, if the then available
amount under the applicable Revolving Committed Amount is less than $5,000,000,
such lesser amount) and (y) in the case of Eurodollar Loans denominated in
Euros, a multiple of 1,000,000 Euros in excess of an amount of Euros having a
Dollar Amount of $5,000,000. Upon receipt of any such notice from the Company,
the Administrative Agent 



                                       10
<PAGE>   16



shall promptly notify each U.S. Lender or each Multicurrency Lender, as
applicable, thereof. Each U.S. Lender or each Multicurrency Lender, as
applicable, will make the amount of its pro rata share of each borrowing
available to the Administrative Agent for the account of the applicable Borrower
at the office of the Administrative Agent specified in subsection 9.2 prior to
11:00 A.M., Charlotte, North Carolina time (or, if the borrowing is to be made
in Euros, prior to the time designated by the Administrative Agent), on the
Borrowing Date and in the currency requested by the Company in funds immediately
available to the Administrative Agent. Such borrowing will then be made
available to the applicable Borrower by the Administrative Agent crediting the
account of the applicable Borrower on the books of such office with the
aggregate of the amounts made available to the Administrative Agent by the U.S.
Lenders or the Multicurrency Lenders, as applicable, and in like funds as
received by the Administrative Agent.

         (b) Canadian Revolving Loans. The Canadian Borrower may borrow under
the Canadian Revolving Committed Amount during the Commitment Period on any
Business Day, provided that the Canadian Borrower shall give the Canadian
Administrative Agent irrevocable notice (which notice must be received by the
Canadian Administrative Agent prior to 11:00 A.M., Toronto, Ontario time, (a)
three Business Days prior to the requested Borrowing Date, if all or any part of
the requested Canadian Revolving Loans are to be initially Eurodollar Loans or
(b) one Business Day prior to the requested Borrowing Date, otherwise),
substantially in the form of Exhibit F, specifying (i) the amount to be borrowed
and the requested currency, (ii) the requested Borrowing Date, (iii) whether the
borrowing is to be of Eurodollar Loans, Base Rate Loans or a combination
thereof, and the respective amounts of each such Type of Loan, and (iv) if the
borrowing is to be entirely or partly of Eurodollar Loans, the respective
lengths of the initial Interest Periods therefor. Each borrowing under the
Canadian Revolving Committed Amount shall be in an amount equal to (x) in the
case of Loans denominated in U.S. Dollars, $5,000,000 or a whole multiple of
$1,000,000 in excess thereof (or, with respect to Base Rate Loans only, if the
then available amount under the Canadian Revolving Committed Amount is less than
$5,000,000, such lesser amount) and (y) in the case of Loans denominated in
Canadian Dollars, a multiple of C$1,000,000 in excess of an amount of Canadian

Currency having a Dollar Amount of $5,000,000. Subject to the foregoing terms,
amount prepaid under this subsection 2.6(a) shall be applied as the applicable
Borrower may elect; provided that if a Borrower fails to specify the application
of a voluntary prepayment then such prepayment shall be applied first to

Loans and then to Eurodollar Loans in direct order of Interest Period
maturities.

         Eligible Reinvestments (such prepayment to be applied as set forth in
         clause (v) below).

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, provided that any such conversion of Eurodollar Loans may
only be made on the last day of an Interest Period with respect thereto. A

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

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 after the date that is one month

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 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 




                                       16
<PAGE>   22


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, 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.

         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).

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. 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 



                                       19
<PAGE>   25


upon receipt in like funds as received. If any payment hereunder (other than
payments on the Eurodollar Loans) becomes due and payable on a day other than a
Business Day, such payment shall be extended to the next succeeding Business
Day, and, with respect to payments of principal, interest thereon shall be
payable at 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 



                                       20
<PAGE>   26


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 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 



                                       21
<PAGE>   27


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) or (b) 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. 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. 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.



                                       22
<PAGE>   28


         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 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 Termination Date. The Swingline Lender may, at any time, in its
         sole discretion, by written 



                                       23
<PAGE>   29


         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 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
         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 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 




                                       25
<PAGE>   31


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 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 


                                       26
<PAGE>   32


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 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



                                       27
<PAGE>   33


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 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, 



                                       28
<PAGE>   34


         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 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,
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 (each a "Term Loan Tranche"):

                  (i) a term loan in the aggregate principal amount of ONE
         BILLION TWO HUNDRED FIFTY MILLION DOLLARS ($1,250,000,000) (the
         "Tranche A Term Loan");

                  (ii) a term loan in the aggregate principal amount of FIVE
         HUNDRED MILLION DOLLARS ($500,000,000) (the "Tranche B Term Loan"); and

                  (iii) a term loan in the aggregate principal amount of ONE
         BILLION DOLLARS ($1,000,000,000) (the "Tranche C Term Loan").

Each 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 may convert up to $950
million of the Tranche A Term Loan to Term Loans denominated in Euros by
requesting a readvance in Euros of up to $950 million 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.



                                       30
<PAGE>   36



         (b) Borrowing Procedures. The funding of the Term Loan Tranches on the
Closing 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 Closing Date, with 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, 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, then the full amount of each Term Loan Tranche shall be
disbursed on the Closing Date 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 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 is 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 



                                       31
<PAGE>   37


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.

         in U.S. Dollars equal to that portion of the Tranche A Term Loan
         denominated in U.S. Dollars as of the Restatement Effective Date (as
         expressed in U.S. Dollars) multiplied by the percentage set forth below
         corresponding to the relevant Principal Amortization Payment Date and
         (B) an amount in Euros equal to that portion of the Tranche A Term Loan

                           (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 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 



                                       34
<PAGE>   40


         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
         Termination Date.

                  (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) 




                                       35
<PAGE>   41


         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 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 




                                       36

                  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;

                           (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;


                                       37
<PAGE>   43


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.



                                       38
<PAGE>   44



         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 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 



                                       39
<PAGE>   45


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.

         3.5. FUNDING LOSSES.

         Each Borrower shall pay to each Lender, upon written request, such

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 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

         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.




                                       40

         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 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




                                       41
<PAGE>   47


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.

         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 



                                       42
<PAGE>   48


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, during the Collateral Period, their
obligations hereunder shall be secured in accordance with the terms of the
Collateral Documents and that, during the Collateral Period, 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.

         3A.9 RELEASES OF CERTAIN GUARANTORS.

         Upon the occurrence of a Credit Improvement Date, the Company may by
written notice to the Administrative Agent request that any Material Domestic
Subsidiary or Additional Credit Party be released from its guaranty pursuant to
this Section 3A. Promptly upon receipt of such written request, the
Administrative Agent shall, at the expense of the Company, execute and deliver a
release acknowledging the termination of the guaranties of the Material Domestic
Subsidiaries and/or Additional Credit Parties specified in such request.

         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 



                                       58
<PAGE>   64


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
NationsBank, 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, 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.



                                       59
<PAGE>   65


         "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": 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 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 



                                       60
<PAGE>   66


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 unsecured non-credit-enhanced debt securities
(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
(7) 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 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); 



                                       61
<PAGE>   67


provided, however, that the Applicable Margin shall be determined by reference
to clause (7) 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 (7)
above and (b) in no event shall (1) the Applicable Margin for Revolving
Eurodollar Loans and Bankers' Acceptances be less than 1.150%, (2) the
Applicable Margin for Term Eurodollar Loans be less than 1.500%, (3) the
Applicable Margin for Base Rate Loans be less than .500% or (4) the Applicable
Margin for Facility Fees be less than .350%, in each case prior to the date that
is six (6) months from the Closing 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.

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
Administrative Agent, the Federal Funds Effective Rate cannot be determined,
then "BACAN U.S. Base Rate" shall mean the BACAN U.S. Prime Rate.

         "BACAN U.S. Prime Rate": means, for any day, the fluctuating rate of
interest publicly announced by the Canadian Administrative Agent as its "prime

Dollars by the Canadian Administrative Agent.

         "Bankers' Acceptance": a depository bill as defined in the Depository

between banks are carried on in U.S. Dollar deposits in the London interbank
market and (ii) if such Eurodollar Loan is denominated in Euros, a day on which

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 




                                       83
<PAGE>   89


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 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.

         SECTION 9. MISCELLANEOUS

         9.1. AMENDMENTS AND WAIVERS.

         Neither this Agreement, any other Credit Document, nor any terms hereof
or thereof may be amended, supplemented or modified except in accordance with
the provisions of this subsection. The Required Lenders may, or, with the
written consent of the Required Lenders, the Administrative Agent may, from time
to time, (a) enter into with the Credit Parties written amendments, supplements
or modifications hereto and to the other Credit Documents for the purpose of
adding any provisions to this Agreement or the other Credit Documents or
changing in any manner the rights of the Lenders or of the Credit Parties
hereunder or thereunder or (b) 



                                       84
<PAGE>   90


waive, on such terms and conditions as the Required Lenders or the
Administrative Agent, as the case may be, may specify in such instrument, any of
the requirements of this Agreement or the other Credit Documents or any Default
or Event of Default and its consequences; provided, however, that no such waiver
and no such amendment, supplement or modification shall (i) reduce the amount or
extend the scheduled date of maturity (including in the case of the Tranche A
Term Loan, any scheduled amortization payment required pursuant to subsection
2.17(d)) of any Note, or reduce the stated rate of any interest or fee payable
hereunder or thereunder or extend the scheduled date of any payment thereof or
increase the amount or extend the expiration date of any Lender's Commitment, in
each case without the consent of each Lender affected thereby, or (ii) amend,
modify or waive any provision of this subsection or reduce the percentage
specified in the definition of Required Lenders or consent to the assignment or
transfer by a Credit Party of any of its rights and obligations under this
Agreement and the Notes or, except pursuant to subsection 9.16 or as the result
of or in connection with an Asset Disposition permitted by subsection 5.2(b),
release all or substantially all of the Collateral or, except as the result of
or in connection with a consolidation, merger or disposition of a Credit Party
permitted under subsection 5.2(b), release the Company or any of the other
Credit Parties from its or their obligations under the Credit Documents, in each
case without the written consent of all the Lenders, or (iii) amend, modify or
waive any provision of Section 8 without the written consent of the then Agents.
Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Credit Parties, the
Lenders, the Agents and all future holders of the Notes. In the case of any
waiver, the Credit Parties, the Lenders and the Agents shall be restored to
their former position and rights hereunder and under the outstanding Notes, and
any Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon.

         9.2. NOTICES.

         All notices, requests and demands to or upon the respective parties

         9.3. NO WAIVER; CUMULATIVE REMEDIES.

         No failure to exercise and no delay in exercising, on the part of an
Agent, any Lender or any Credit Party, any right, remedy, power or privilege
hereunder or under the Notes shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder or
thereunder preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege. The rights, remedies, powers and
privileges herein provided are cumulative and not exclusive of any rights,
remedies, powers and privileges provided by law.

         9.4. SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         All representations and warranties made hereunder, in the Notes and in
any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement,
the Notes and the other Credit Documents and the making of the Loans and the
issuance or extension of Letters of Credit hereunder.

         9.5. PAYMENT OF EXPENSES AND TAXES.

         The Company agrees (a) to pay or reimburse each Agent for all its
reasonable out-of-pocket costs and expenses incurred in connection with the
development, preparation and execution of, and any amendment, supplement or
modification to, this Agreement, the Notes and the other Credit Documents and
any other documents prepared in connection herewith or therewith, and the
consummation and administration of the transactions contemplated hereby and
thereby, including, without limitation, the reasonable fees and disbursements of
counsel (including special Canadian counsel) to the Agents, (b) to pay or
reimburse each Lender and the Administrative Agent 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 and 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 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
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 Loans and Letters of Credit and any
such other documents, including, without limitation, any of the foregoing
relating to the violation of, noncompliance with or liability under, any
environmental or other law applicable to the operations of the Borrowers, any of
their Subsidiaries or any of the their respective properties (all the foregoing
in this clause (d), collectively, the "indemnified liabilities"), 




                                       87
<PAGE>   93


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 Agent or any such Lender or (ii) legal
proceedings commenced against such Agent or any such Lender by any security
holder or creditor thereof arising out of and based upon rights afforded any
such security holder or creditor solely in its capacity as such. 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 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, with the consent of (x)
so long as no Event of Default exists, the Company and (y) the Administrative
Agent (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 delivered to the Administrative Agent for its acceptance and
recording in the Register; 



                                       88
<PAGE>   94


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) $10,000,000 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 purposes of this Agreement. The
Register shall be available for inspection by the Company 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 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.



                                       89
<PAGE>   95


         (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) Nothing herein shall prohibit any Lender from pledging or assigning
any Note to any Federal Reserve Bank in accordance with applicable law.

         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
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 



                                       90
<PAGE>   96


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

         9.18. PRUDENTIAL INTERCREDITOR AGREEMENT.

         The Lenders hereby agree that the Administrative Agent, on behalf of
the Lenders, may enter into an intercreditor agreement, substantially in the
form of Exhibit J, with The Prudential Insurance Company of American
("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
intercreditor agreement shall provide, among other things, for the pro rata
sharing among the Lenders and Prudential of any proceeds of the Collateral or
the guarantees under Section 3A.

         9.19 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, (i) 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.

         9.20 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 



                                       94
<PAGE>   100


         banking business at such offices 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.


                            (signature pages follow)
