NOTE E.     Contingencies

            The Company and its subsidiaries are involved in a number of
lawsuits, all of which have arisen in the ordinary course of the Company's
business. The Company is unable to predict the outcome of these matters, but
does not believe, based upon currently available facts, that the ultimate
resolution of such matters will have a material adverse effect on the
consolidated financial statements of the Company.

            The Company is subject to other loss contingencies pursuant to
federal, state, local, and foreign environmental laws and regulations. These
contingencies include possible obligations to remove or mitigate the effects on
the environment of the past disposal or release of certain chemical substances
at various sites (remediation costs). The Company continues to evaluate the
amount of these remediation costs and periodically adjusts its reserve for
remediation costs and its estimate of additional environmental loss
contingencies based on progress made in determining the magnitude, method and
timing of the remedial actions that may be required by government authorities
and an evaluation of the Company's potential liability in relation to the
liability and financial resources of any other potentially responsible parties.

            At June 30, 1997, the Company's environmental reserve totaled 
$48 million, which reflected the Company's latest assessment of potential future
remediation costs associated with existing sites. A significant portion of the
reserve is related to the Beaver Valley plant site, located in Monaca,
Pennsylvania. The reserve



                                     - 5 -
<PAGE>
 
gives recognition to a work plan, between the Company and the Pennsylvania
Department of Environmental Protection (PADEP), for testing, risk assessment,
remedial process design and remediation of conditions at the Beaver Valley
plant. The reserve also reflects an agreement between the Company and another
responsible party whereby that party has agreed to pay for approximately 50
percent of the costs associated with the Beaver Valley plant work plan. The
Company sold the Beaver Valley plant assets to NOVA Chemicals Inc. (NOVA) on
September 30, 1996, but currently retains ownership of the land at the Beaver
Valley plant site, substantial portions of which are being leased to NOVA. The
Company has retained responsibility for certain remediation of the land at the
Beaver Valley plant site under the work plan and for certain additional
remediation that may be required by PADEP pursuant to the Pennsylvania Land
Recycling and Environmental Remediation Standards Act.

            The remainder of the reserve is related to four other plant sites
and one federal Superfund site for amounts ranging from $2 million to $14
million per site. The Company is involved in administrative proceedings or
lawsuits relating to eight other Superfund sites. However, the Company
estimates, based on currently available information, that potential loss
contingencies associated with these sites, individually and in the aggregate,
are not significant. Substantially all amounts reserved are expected to be paid
out over the next five to ten years.

            The Company relies upon remedial investigation/feasibility studies
(RI/FS) at each site as a basis for estimating remediation costs at the site.
The Company has completed RI/FS or preliminary assessments at most of its sites.
However, selection of the remediation method and the cleanup standard to be
applied are, in most cases, subject to approval by the appropriate government
authority. Accordingly, the Company may have possible loss contingencies in
excess of the amounts reserved to the extent the scope of remediation required,
the final remediation method selected and the cleanup standard applied vary from
the assumptions used in estimating the reserve. The Company estimates that the
upper range of these possible loss contingencies should not exceed the amount
accrued by more than $65 million.

            The extent of loss related to environmental matters ultimately
depends upon a number of factors, including technological developments, changes
in environmental laws, the number and ability to pay of other parties involved
at a particular site and the Company's potential involvement in additional
environmental assessments and cleanups. Based upon currently known facts,
management believes that any remediation costs the Company may incur in excess
of the amounts reserved or disclosed above would not have a material adverse
impact on the Company's consolidated financial statements.

            The Company and the other principal responsible party (PRP) at the
Beaver Valley site have reached an agreement with the U.S. government whereby
the government will pay 28.5 percent of the costs incurred by the Company and
the other PRP for remediation of substantial portions of the Beaver Valley site.

            The Company and the Atlantic Richfield Company (ARCO) are parties to
an agreement whereby the Company has indemnified ARCO against certain claims or
liabilities that ARCO may incur relating to ARCO's former ownership and
operation of the oxygenates and polystyrenics businesses of the Company,
including liabilities under laws relating to the protection of the environment
and the workplace and liabilities arising out of certain litigation. ARCO has
indemnified the Company with respect to claims or liabilities and other matters
of litigation not related to the assets or businesses reflected in the
consolidated financial statements. ARCO has also indemnified the Company for
certain federal, foreign, state, and local taxes that might be assessed upon
audit of the operations of the Company included in its consolidated financial
statements for periods prior to the July 1, 1987 formation of the Company.

NOTE F.     Earnings Per Common Share

            Earnings per common share for the three- and six-month periods ended
June 30, 1997 are computed based on 96.9 million weighted average shares
outstanding. Earnings per common share for the three- and six-month periods
ended June 30, 1996 are computed based on 96.6 million weighted average shares
outstanding. The effect of stock options issued under the 1987 Executive Long-
Term Incentive Plan and the 1990 Long-Term Incentive Plan on the computation of
primary and fully diluted earnings per common share was not material.

            In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per
Share," establishing standards for computing and presenting earnings per share
(EPS). SFAS No. 128 is effective for financial statements issued for periods
ending after December 15, 1997 and requires restatement of all prior-period EPS
data presented. Earlier application is not permitted. The implementation of SFAS
No. 128 is not expected to have a material effect on the reported EPS of the
Company.

                Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


                                   Overview

            The Company manufactures and markets intermediate chemicals and
specialty products, operating in a single industry segment. It conducts business
primarily in the Americas, Europe, and the Asia Pacific region.

            Each of the Company's two principal manufacturing processes yields
its key product, propylene oxide (PO), and one of two co-products, styrene
monomer (SM) or tertiary butyl alcohol (TBA). The Company also manufactures
numerous derivatives of PO and TBA. Among these are polyols, a key derivative of
PO, and methyl tertiary butyl ether (MTBE), a principal derivative of TBA. The
Company also manufactures and markets toluene diisocyanate (TDI). TDI and
polyols are combined in the manufacture of polyurethanes. MTBE is used in
oxygenated fuels and as an octane additive.

            During the second quarter 1997, the Company initiated a
restructuring program designed to reduce annual fixed and controllable costs,
currently about $750 million, by about $150 million. The program seeks to
simplify the organization and streamline processes in plant operations,
commercial activities, corporate staff functions, and research and development.
The restructuring efforts are expected to continue through the end of 1998, with
the cost reductions substantially in place by 1999. A key element of the program
is the reduction of 800 to 1,100 employee and contractor positions on a current
base of 5,300 positions. The Company expects to take a special charge to
earnings in the second half of 1997 to account for the costs of the
restructuring program.

Product Volumes

            Sales and other operating revenues include the sales and processing

quarter in both 1997 and 1996. The 1996 data include SM derivatives sales
volumes for periods prior to the September 30, 1996 sale of the plastics
business.


Second Quarter 1997 versus Second Quarter 1996

Net Income

            Net income for the second quarter 1997 was $35 million compared with
$81 million in the second quarter 1996. The $46 million decline was primarily
due to lower margins for most products and increased costs as a result of
scheduled maintenance turnarounds, partly offset by the benefit from higher PO
and derivatives volumes.


Revenues

            Revenues of $956 million in the second quarter 1997 were comparable
to revenues of $959 million in the second quarter 1996, as lower average sales
prices offset the benefit of higher sales volumes. The lower average 1997 sales
prices were primarily due to lower prices for PO derivatives, TDI, and MTBE,
partly offset by higher prices for PO. Factors contributing to the lower 1997
prices included stronger price competition in PO derivatives and TDI markets,
the expiration of most of the Company's long-term MTBE contracts, and the effect
of a stronger U.S. dollar.

            Volumes for core products increased 17 percent in the second quarter
1997 versus the prior year period. The increase reflected higher volumes for PO
derivatives and, to a lesser extent, TDI. PO derivatives volumes benefited from
improved demand and temporary supply shortages for certain products. TDI volumes
were higher due to the Olin acquisition and the increased availability of TDI
from a plant in France. The French plant was under repair and operated at
restricted rates in the 1996 period. The loss of SM derivatives volumes through
the sale of the plastics business was essentially offset by increased SM volumes
processed for the buyer of the plastics business. Other SM volumes declined due
to the timing of export shipments.


Gross Profit

            Gross profit of $161 million in the second quarter 1997 decreased
$55 million from $216 million in the 1996 second quarter, reflecting lower
margins for most products and higher maintenance costs. Gross profit was 16.8
percent of sales in the second quarter 1997 compared to 22.5 percent in the 1996
period. The decline in gross profit margins is due to the combined effect of
lower sales prices and higher costs for most feedstocks in the second quarter
1997 versus the 1996 period. Turnaround costs of $23 million in the 1997 period
were $16 million higher, reflecting an increase in the number of scheduled plant
maintenance turnarounds versus the prior year period. The Company estimates that
plant turnaround costs will total $23 million in the second half of 1997.


Other

            Other expense of $1 million in 1997 compared to income of $9 million
in 1996. The $10 million decrease is primarily due to a benefit from an
insurance settlement included in the second quarter 1996 and lower interest
income as a result of lower levels of cash and cash equivalents in the 1997
period.

            The Company expects its 1997 effective tax rate to be 34.0 percent
compared to a 28.3 percent effective tax rate used in the second quarter 1996
and a final 1996 effective tax rate of 28.5 percent. The final 1996 rate
reflected utilization of capital loss carryforwards and the utilization of
foreign tax credits pursuant to the tax sharing agreement with ARCO.


Six Months Ended June 30, 1997 versus 1996

Net Income

            Net income for the six months ended June 30, 1997 was $83 million
compared with $187 million for the comparable 1996 period. The $104 million
decline was primarily due to lower margins for PO derivatives, TDI, and MTBE,
which were only partly offset by the benefit from higher core product volumes.
Maintenance costs were also higher due to an increase in the number of scheduled
plant turnarounds in 1997.


Revenues

            Revenues of $1,985 million in the first six months of 1997 increased
two percent compared to revenues of $1,941 million in the first six months of
1996, as higher net volumes were substantially offset by lower average sales
prices. Volumes for core products increased 14 percent in the first six months
of 1997 versus the prior year period. The increase reflected higher TDI volumes
due to the Olin acquisition and the increased availability of TDI from the plant
in France. Core product sales also reflected higher volumes for PO derivatives,
which benefited from improved demand and temporary supply shortages for certain
products. SM volumes declined slightly; the loss of SM derivatives volumes
through the sale of the plastics business were essentially replaced by increased
SM volumes processed for the buyer of the plastics business. TBA and derivative
volumes decreased two percent, mainly due to a weak MTBE market in the first
quarter 1997.

            Average sales prices were generally lower in the 1997 period versus
1996. Contributing to the weakness in 1997 prices were stronger competition in
PO derivatives and TDI markets, expiration of most of the Company's long-term
MTBE contracts, industry concerns over SM capacity additions in Asia, and the
effect of a stronger U.S. dollar.


Gross Profit

            Gross profit of $346 million in the first six months of 1997
decreased $122 million from $468 million in the 1996 period, reflecting lower
margins for most products and increased plant turnaround maintenance costs.
Gross profit was 17.4 percent of sales in the 1997 period compared to 24.1
percent in the 1996 period. The decline in gross profit margins is due to the
combined effect of lower sales prices and higher feedstock costs in the 1997
period versus the 1996 period.


Other

            Other expense of $2 million in the 1997 period compared to income of
$18 million in the 1996 period. The $20 million decrease reflects the benefit of
an insurance settlement included in the 1996 period, lower interest income as a
result of lower levels of cash and cash equivalents in the 1997 period, and
higher foreign exchange losses in 1997 due to the stronger U.S. dollar.

            The Company expects its 1997 effective tax rate to be 34.0 percent
compared to a 31.0 percent effective tax rate used in the first six months of
1996 and a final 1996 effective tax rate of 28.5 percent. The final 1996 rate
reflected utilization of capital loss carryforwards and the utilization of
foreign tax credits pursuant to the tax sharing agreement with ARCO.


                              Financial Condition

Liquidity and Capital Resources

            As of June 30, 1997, the company had $88 million in cash and cash
equivalents compared with $70 million at December 31, 1996. The Consolidated
Statement of Cash Flows for the six months ended June 30, 1997 shows that net
cash flows provided by operating activities were $210 million, whereas net cash
flows used by investment and financing activities were $92 million and $96
million, respectively.

            Investment activities for the first six months 1997 included capital
expenditures of $127 million. The Company's 1997 budget for plant and equipment
is $453 million and is part of a five-year, $2.6 billion program primarily
devoted to capacity expansion and growth. Minority interest includes equity
contributions designated for specific capital projects. At June 30, 1997, the
unexpended amounts were classified as deferred charges and other assets in the
balance sheet.

            During July 1997, the Company negotiated a new revolving credit
facility comprised of a $200 million credit agreement and a $300 million credit
agreement, for a total commitment of $500 million. The $200 million credit
agreement is renewable annually; the $300 million credit agreement has a term of
five years. This facility replaces the previous $300 million revolving credit
agreement. The new facility has a restrictive financial covenant that requires
the Company to maintain a minimum consolidated net worth, as defined in the
agreements, of $1.5 billion. The Company has no outstanding borrowing against
the facility, which is used to back up the Company's commercial paper borrowing.

            During the second quarter 1997, the Company filed a shelf
registration statement on Form S-3 with the Securities and Exchange Commission
for up to $350 million of debt securities. During the first quarter 1997, the
Company executed an agreement to refinance two Dutch bank loans, having a
combined principal balance of 300 million Dutch guilders ($158 million) and due
in 1997, with one loan due in 2002.

            The Company paid dividends totaling $136 million during the first
six months 1997, including a dividend of $.70 per share, totaling $68 million,
during the quarter ended June 30, 1997. On July 17, 1997, the Board of Directors
declared a dividend of $.70 per share on the Company's common stock, payable
September 5, 1997.

            During the first quarter 1997, the Company revised its hedging
strategy with respect to capital commitments related to construction of the new
PO/SM plant in Rotterdam, the Netherlands. To take advantage of the strong U.S.
dollar, the Company effectively terminated forward contracts in the notional
amount of $127 million, and entered into purchased option contracts for
approximately the same notional amount. Gains on the purchased options will be
deferred and offset against the plant's construction costs. There were no
deferred hedging gains as of June 30, 1997.

            It is expected that future cash requirements for capital
expenditures, dividends and debt repayments will be met by cash generated from
operating activities and additional borrowing.

Statement of Financial Accounting Standards Not Yet Adopted

            In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per
Share," establishing standards for computing and presenting earnings per share
(EPS). SFAS No. 128 is effective for financial statements issued for periods
ending after December 15, 1997 and requires restatement of all prior-period EPS
data presented. Earlier application is not permitted. The implementation of SFAS
No. 128 is not expected to have a material effect on the reported EPS of the
Company.

Item 1.     Legal Proceedings

            Reference is made to the disclosures on page 10 of the Company's
1996 Annual Report on Form 10-K and on page 12 of the Company's first quarter
1997 Form 10-Q Report regarding other litigation.

            The Company responded in writing to the Commission's Statement of
Objections on June 11, 1997 and requested an oral hearing to present its
arguments. That hearing has been scheduled for August 6-8, 1997. The Company
believes that the provisions in question are consistent with European law and
are valid and enforceable and has so argued to the Commission.

Item 5.     Other Information

CAUTIONARY STATEMENT FOR PURPOSES OF THE PRIVATE SECURITIES LITIGATION REFORM 
ACT OF 1995


            The Private Securities Litigation Reform of 1995 (the "Act")
provides a safe harbor for forward-looking statements to encourage companies to
provide prospective information about their companies without fear of litigation
so long as those statements are identified as forward-looking and are
accompanied by meaningful, cautionary statements identifying important factors
that could cause actual results to differ materially from those projected in the
statement. The Company is hereby filing cautionary statements to take advantage
of the safe harbor provisions of the Act.

            From time to time the Company's management may wish to make forward-
looking statements to inform more fully existing and potential security holders
regarding various matters, including without limitation, projections regarding
future income, sales volumes, production and capital spending, as well as
predictions as to the timing and success of specific strategic initiatives, such
as downstream integration, capacity additions, acquisitions, cost reduction
programs, efficiency improvements, and new product and new market development.
Forward-looking statements are generally accompanied by words such as estimate,
project, predict, or expect that convey the uncertainty of future events or
outcomes. The Company believes that the following are important factors that
could cause the Company's actual results to differ materially from projections,
forecasts, or estimates made by, or on behalf of, the Company.

     -   Changes in the competitive environment, including the emergence of new
         competitors; the rate of capacity additions by competitors; the
         intensification of price competition in the Company's markets; and the
         introduction of new or substitute products by competitors.

     -   General economic conditions and specific chemical industry cycles,
         including the dependence of certain Company products on cyclical demand
         in the housing and automotive markets.

     -   Changes in the cost and availability of feedstocks, reflecting changes
         in the supply/demand balance in petrochemical feedstock, natural gas,
         and crude oil markets; and changes in the cost and availability of
         utilities, such as steam and electricity.


     -   The level of worldwide demand growth for the Company's products,
         including the effect on demand of changes in the political, regulatory
         and economic climates of developing countries in Latin America, Eastern
         Europe and the Asia Pacific region.

     -   Changes in or additions to federal, state, local, and foreign
         government legislation and regulations that may affect the demand for
         or the value of the Company's products, the cost of producing them, or
         the general levels of construction, maintenance, and operating costs.

     -   Technological innovations by competitors.

     -   Hazards related to chemical operations. The Company's operations can be
         affected by disruptions at its facilities as well as at those of its
         suppliers or customers.

     -   The Company's ability to implement its cost reduction program as well
         as the cost, timing and degree of success of such efforts.

     -   The Company's ability to complete construction projects on schedule.

            The factors identified in this statement are believed to be
important factors, but not necessarily all of the important factors, that could
cause actual results to differ materially from those expressed in any forward-
looking statement made by or on behalf of the Company. Unpredictable or unknown
factors not discussed herein could also have material adverse effects on 
forward-looking statements.

                                 THE FACILITY


2.   The Facility

2.1  Grant of the Facility  The Banks grant to the Borrower, upon the terms and
subject to the conditions hereof, a term loan facility in an aggregate amount of
NLG300,000,000.

2.2  Purpose and Application  The Facility is intended to refinance the Existing
Facilities and, accordingly, the Borrower shall apply all amounts raised by it
hereunder in or towards satisfaction of such purpose and neither the Agent, the
Arranger and the Banks nor any of them shall be obliged to concern themselves
with such application.

2.3  Condition Precedent Documents  Save as the Banks may otherwise agree, the
Borrower may not deliver any Notice of Drawdown hereunder unless the Agent has
confirmed to the Borrower and the Banks that it has received all of the
documents listed in the Third Schedule (Condition Precedent Documents) and that
each is, in form and substance, satisfactory to the Agent.

2.4  Banks' Rights and Obligations Several  The obligations of each Bank
hereunder are several and the failure by a Bank to perform its obligations
hereunder shall not affect the obligations of the Borrower, the Guarantor or any
Bank towards any other party hereto nor shall any other party be liable for the
failure by such Bank to perform its obligations hereunder.  The rights of each
Bank hereunder are several and each Bank may, save as otherwise provided herein,
separately enforce those rights.

3.   Availability of the Facility

3.1  Drawdown Conditions  An Advance will be made by the Banks to the Borrower
if:

     (a) prior to 10.00 a.m. (London time) on the third business day before the
         proposed date for the making of such Advance, the Agent has received
         from the Borrower a Notice of Drawdown therefor, receipt of which shall
         oblige the Borrower to borrow the amount therein requested on the date
         therein stated upon the terms and subject to the conditions contained
         herein;

     (b) the proposed date for the making of such Advance is a business day
         which is or precedes the Termination Date;

     (c) the proposed date for the making of such Advance is not less than five
         business days after the date upon which the previous Advance (if any)
         was made hereunder;

     (d) the proposed amount of such Advance is (i) an amount or integral
         multiple of NLG10,000,000 which is less than the amount of the
         Available Facility or (ii) equal to the amount of the Available
         Facility;

     (e) the interest rate applicable to such Advance during its first Interest
         Period would not fall to be determined pursuant to Clause 6.1 (Market
         Disruption); and

                                      -10-
<PAGE>
 
     (f) no Event of Default or Potential Event of Default has occurred and the
         representations set out in Clause 12 (Representations) are true on and
         as of the proposed date for the making of such Advance.

3.2  Notice to Banks  The Agent shall notify each Bank of the receipt of a
Notice of Drawdown, the details specified in such Notice of Drawdown and the
amount of such Bank's participation in the proposed Advance.

3.3  Each Bank's Participation  Each Bank will participate through its Facility
Office in each Advance made pursuant to Clause 3.1 (Drawdown Conditions) in the
proportion borne by its Available Commitment to the Available Facility
immediately prior to the making of that Advance.

3.4  Reduction of Available Commitment  If a Bank's Available Commitment is
reduced in accordance with the terms hereof after the Agent has received the
Notice of Drawdown for an Advance, then the amount of that Advance shall be
reduced accordingly.

3.5  Expiry of Termination Date  Each Bank's Available Commitment shall
immediately be reduced to zero on the Termination Date.

                                   INTEREST


4.   Interest Periods

4.1  Interest Periods  The period for which an Advance is outstanding shall be
divided into successive periods each of which (other than the first) shall start
on the last day of the preceding such period.

4.2  Duration  The duration of each Interest Period shall, save as otherwise
provided herein, be one, three, six or twelve months, in each case as the
Borrower may by not less than five business days' prior notice to the Agent
select  Provided that:

     (a) if the Borrower fails to give such notice of its selection in relation
         to an Interest Period, the duration of that Interest Period shall,
         subject to paragraphs (b) and (c) below, be six months;

     (b) any Interest Period which begins during or at the same time as any
         other Interest Period shall end at the same time as that other Interest
         Period; and

     (c) any Interest Period which would otherwise end during the month
         preceding, or extend beyond, the Repayment Date shall be of such
         duration that it shall end on the Repayment Date.

4.3  Consolidation of Advances  If two or more Interest Periods end at the same
time, then, on the last day of those Interest Periods, the Advances to which
they relate shall be consolidated into and treated as a single Advance.

5.   Payment and Calculation of Interest

5.1  Payment of Interest  On the last day of each Interest Period (and, in the
case of any Interest Period of more than six months duration, on the last day of
each successive period of six months during such Interest Period) the Borrower
shall pay accrued interest on the Advance to which such Interest Period relates.

5.2  Calculation of Interest  The rate of interest applicable to an Advance from
time to time during an Interest Period relating thereto shall be the rate per
annum which is the sum of the Margin and LIBOR on the Quotation Date therefor.

5.3  Notice to Banks   The Agent shall notify each Bank of the interest payable
prior to the last day of each Interest Period.

6.   Alternative Interest Rates

6.1  Market Disruption  If:

     (a) the Agent determines that at or about 11.00 a.m. (London time) on the
         Quotation Date for an Interest Period in respect of an Advance none or
         only one of the Reference Banks

                                      -12-
<PAGE>
 
         was offering to prime banks in the London Interbank Market deposits in
         Guilders for the proposed duration of such Interest Period; or

     (b) before the close of business in London on the Quotation Date for an
         Interest Period in respect of an Advance, the Agent has been notified
         by a Bank or each of a group of Banks to whom in aggregate thirty-five
         per cent. or more of such Advance is (or, in the case of an undrawn
         Advance, if such Advance were then made, would be) owed that the rate
         at which such deposits were being so offered does not accurately
         reflect the cost to it of obtaining such deposits,

then, notwithstanding the provisions of Clause 4 (Interest Periods) and Clause 5
(Payment and Calculation of Interest):

            (i)    if paragraph (a) above applies, the duration of that Interest
                   Period shall be one month or, if less, such that it shall end
                   on the Repayment Date; and

            (ii)   if either paragraph (a) or (b) above applies, the rate of
                   interest applicable to such Advance from time to time during
                   such Interest Period shall be the rate per annum which is the
                   sum of the Margin and the rate per annum determined by the
                   Agent to be the arithmetic mean (rounded upwards, if not
                   already such a multiple, to the nearest whole multiple of 
                   one-sixteenth of one per cent.) of the rates notified by each
                   Bank to the Agent before the last day of such Interest Period
                   to be those which express as a percentage rate per annum the
                   cost to each Bank of funding from whatever sources it may
                   select its portion of such Advance during such Interest
                   Period.

6.2  Substitute Basis or Repayment  If (i) either of those events mentioned at
paragraphs (a) and (b) in Clause 6.1 (Market Disruption) occurs in relation to
an Advance and an Interest Period during which such Advance is (or was) to be
outstanding in Guilders or (ii) by reason of circumstances affecting the London
Interbank Market during any period of three consecutive business days none or
only one of the Reference Banks offers deposits in Guilders to prime banks in
the London Interbank Market, then:

     (a) the Agent shall notify the Borrower and the Banks of such event;

     (b) if the Agent so requires, within five days of such notification the
         Agent and the Borrower shall enter into negotiations with a view to
         agreeing a substitute basis (1) for determining the rates of interest
         from time to time applicable to the Advances and/or (2) upon which the
         Advances may be maintained (whether in Guilders or some other currency)
         thereafter and any such substitute basis that is agreed shall take
         effect in accordance with its terms and be binding on each party hereto
         Provided that the Agent may not agree any such substitute basis without
         the prior consent of each Bank; and

                                      -13-
<PAGE>
 
     (c) if the Agent has required the Borrower to enter into such negotiations,
         the Agent may declare (any such declaration to be binding on the
         Borrower) that each Advance shall become due and payable on the last
         day of its then current Interest Period unless by then a substitute
         basis has been agreed in relation thereto.

                    REPAYMENT, CANCELLATION AND PREPAYMENT


7.   Repayment

The Borrower shall repay the Loan in full on the Repayment Date.

8.   Cancellation and Prepayment

8.1  Cancellation  The Borrower may, by giving to the Agent not less than
fifteen business days' prior notice to that effect, cancel the whole or any part
(being an amount or integral multiple of NLG20,000,000) of the Available
Facility; any such cancellation shall reduce the Available Commitments of the
Banks rateably.

8.2  Prepayment  The Borrower may, if it has given to the Agent not less than
fifteen business days' prior notice to that effect, prepay the whole of any
Advance or any part of any Advance (being an amount or integral multiple of
NLG20,000,000) on the last day of any Interest Period relating to that Advance
which ends after the Termination Date; any such prepayment shall reduce rateably
the remaining obligations of the Borrower under Clause 7 (Repayment).

8.3  Notice of Cancellation or Prepayment  Any notice of cancellation or
prepayment given by the Borrower pursuant to Clause 8.1 (Cancellation) or Clause
8.2 (Prepayment) shall be irrevocable, shall specify the date upon which such
cancellation or prepayment is to be made and the amount of such cancellation or
prepayment and, in the case of a notice of prepayment, shall oblige the Borrower
to make such prepayment on such date.

8.4  Repayment of a Bank's Share of the Loan  If any Bank claims indemnification
from the Borrower under Clause 9.2 (Tax Indemnity) or Clause 11.1 (Increased
Costs) or if any Obligor is required to make an additional payment under Clause
9.1 (Tax Gross-Up) and within thirty days thereafter the Agent receives from the
Borrower at least ten business days' prior notice (which shall be irrevocable)
of the Borrower's intention to repay such Bank's share of the Loan, the Borrower
shall on the last day of each of the then current Interest Periods repay such
Bank's portion of the Advance to which such Interest Period relates;  any
repayment so made after the Termination Date shall reduce rateably the remaining
obligations of the Borrower under Clause 7 (Repayment).

8.5  No Further Advances  A Bank for whose account a repayment is to be made
under Clause 8.4 (Repayment of a Bank's Share of the Loan) shall not be obliged
to participate in the making of Advances on or after the date upon which the
Agent receives the Borrower's notice of its intention to repay such Bank's share
of the Loan, on which date such Bank's Available Commitment shall be reduced to
zero.

8.6  No Other Repayments and No Reborrowing  The Borrower shall not repay all or
any part of the Loan except at the times and in the manner expressly provided
for in this Agreement and shall not be entitled to reborrow any amount repaid or
cancelled.

                                RISK ALLOCATION


9.   Taxes

9.1  Tax Gross-up  All payments to be made by either of the Obligors to any Bank
or the Agent on its behalf hereunder shall be made free and clear of and without
deduction for or on account of tax unless such Obligor is required to make such
a payment subject to the deduction or withholding of tax, in which case the sum
payable by such Obligor in respect of which such deduction or withholding is
required to be made shall be increased to the extent necessary to ensure that,
after the making of the required deduction or withholding, such Bank or the
Agent on its behalf receives and retains (free from any liability in respect of
any such deduction or withholding) a net sum equal to the sum which it would
have received and so retained had no such deduction or withholding been made or
required to be made.

9.2  Tax Indemnity  Without prejudice to the provisions of Clause 9.1 (Tax
Gross-up), if any Bank or the Agent on its behalf is required to make any
payment on account of tax (not being a tax imposed on and calculated by
reference to the net income) on or calculated by reference to the amount of such
Bank's share of the Advances or on or in relation to any sum received or
receivable hereunder by such Bank or the Agent on its behalf (including any sum
received or receivable under this Clause 9) or any liability in respect of any
such payment is asserted, imposed, levied or assessed against such Bank or the
Agent on its behalf, the Borrower shall, upon demand of the Agent, promptly
indemnify such Bank or the Agent, as the case may be, against such payment or
liability, together with any interest, penalties, costs and expenses payable or
incurred in connection therewith.

9.3  Claims by Banks  A Bank intending to make a claim pursuant to Clause 9.2
(Tax Indemnity) shall notify the Agent of the event by reason of which it is
entitled to do so within 90 days of the date on which such Bank's Facility
Office ought reasonably to have become aware of such Bank's entitlement to make
such a claim, whereupon the Agent shall notify the Borrower thereof.  In the
event that such Bank or the Agent fails to so notify the Borrower within the
period provided in the preceding sentence, the Borrower shall not be obliged to
indemnify such Bank for all or part of any payment or liability under Clause 9.2
(Tax Indemnity) to the extent that such amount is imposed with respect to
payments made prior to the date which is 90 days prior to the date on which such
Bank or the Agent gives notice to the Borrower of the event by reason of which
it is entitled to be so indemnified.  Nothing herein contained shall require
such Bank to disclose any confidential information relating to the organisation
of its affairs.

9.4  Tax Credit  In the event that an additional payment is made under Clause
9.1 (Tax Gross-up), Clause 9.2 (Tax Indemnity) or Clause 11.1 (Increased Costs)
and the person for whose benefit such payment is made, in its reasonable bona
fide opinion, determines that it has received or been granted (and has derived
full use and benefit from) a credit against, relief or remission for, or
repayment of, any tax paid or payable by it in respect of or calculated with
reference to the deduction or withholding giving rise to such additional payment
or, in the case of an additional payment made pursuant to Clause 11.1 (Increased
Costs), with reference to the liability, expense or loss to which the payment
giving rise to the additional payment relates, such person shall, to the extent
that it can do so without prejudice to the retention of the amount of such
credit, relief, remission or repayment, pay to the relevant Obligor such amount
as such person shall, in its reasonable opinion (exercised in good faith) have
concluded to be attributable to such

                                      -16-
<PAGE>
 
deduction or withholding or, as the case may be, such liability, expense or
loss.  Any such payment shall be conclusive evidence of the amount due to the
relevant Obligor hereunder and shall be accepted by such Obligor in full and
final settlement of its rights of reimbursement hereunder in respect of such
deduction or withholding or, as the case may be, in respect of the additional
payment related to any liability, expense or loss.  Nothing herein contained
shall interfere with the right of the Agent or any Bank to arrange its tax
affairs in whatever manner it thinks fit or oblige the Agent or any Bank to
disclose any information relating to its tax affairs or any computation made in
respect thereof and, in particular, neither the Agent nor any Bank shall be
under any obligation to claim credit, relief, remission or repayment from or
against its corporate profits or similar tax liability in respect of the amount
of such deduction or withholding or, as the case may be, in respect of the
additional payment related to any liability, expense or loss in priority to any
other claims, reliefs, credits or deductions available to it.

9.5  United States Withholding Tax  The Agent and each Bank agrees that:

     (a) on or prior to the date of this Agreement (or in the case of a Bank
         which becomes a party hereto pursuant to a transfer or assignment, on
         or prior to the date on which the relevant transfer or assignment
         becomes effective), it shall deliver to the Borrower and (in the case
         of each Bank) the Agent two duly completed and executed originals of
         United States Internal Revenue Service Form 1001 or Form 4224 and Form
         W-8 or Form W-9, as the case may be, (or successor forms) or other
         manner of certification to establish that such Bank or the Agent is
         exempt from withholding or deduction of any United States federal
         income taxes and shall deliver, extensions or renewals thereof, upon
         the request of the Borrower, on or before the date that any such form
         expires or becomes obsolete and after the occurrence of any event
         requiring a change in the most recent form previously delivered by it,
         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 Bank or the Agent
         from duly completing and delivering any such form with respect to it
         and such Bank or the Agent so advises the Borrower and (in the case of
         any Bank) the Agent; and

     (b) by its execution of this Agreement, it certifies that it is entitled to
         receive payments from the Obligors under this Agreement without
         deduction or withholding of any United States federal income taxes; and

     (c) the Borrower is relying upon the forms and certification delivered by
         the Agent and each Bank pursuant to sub-paragraphs (a) and (b) above in
         providing the representation contained in Clause 12.4 (No Deduction or
         Withholding) insofar as such representation relates to the deduction or
         withholding of United States federal income taxes; and

     (d) the Obligors shall not be required to make any additional payment to
         any Bank or the Agent on its behalf pursuant to Clause 9.1 (Tax Gross-
         up) or Clause 9.2 (Tax Indemnity) if such Bank or the Agent, as the
         case may be, fails to complete or deliver any form required to be
         completed or delivered by it pursuant to sub-paragraph (a) above or if
         such form or the certification in sub-paragraph (b) above is not true
         in all material respects and such additional payment would not have
         been payable if such

                                      -17-
<PAGE>
 
         Bank or the Agent, as the case may be, had completed and delivered such
         form and such form and certification had been true in all material
         respects.

10.  Tax Receipts

10.1 Notification of Requirement to Deduct Tax  If, at any time, either of the
Obligors is required by law to make any deduction or withholding from any sum
payable by it hereunder (or if thereafter there is any change in the rates at
which or the manner in which such deductions or withholdings are calculated),
such Obligor shall promptly notify the Agent.

10.2 Evidence of Payment of Tax  If either of the Obligors makes any payment
hereunder in respect of which it is required to make any deduction or
withholding, it shall pay the full amount required to be deducted or withheld to
the relevant taxation or other authority within the time allowed for such
payment under applicable law and shall request such authority for an original
receipt (or a certified copy thereof) issued by such authority evidencing the
payment to such authority of all amounts so required to be deducted or withheld
in respect of that Bank's share of such payment which upon receipt by such
Obligor shall be promptly delivered to the Agent for each Bank.

11.  Changes in Circumstances

11.1 Increased Costs  If, by reason of (i) any change in law or in its
interpretation or administration (other than the adoption of a new tax or change
in an existing tax, which would be subject to the indemnification provisions
under Clause 9.2 (Tax Indemnity)) and/or (ii) compliance with any Capital
Adequacy Requirement or any other request from or requirement of any central
bank or other fiscal, monetary or other authority:

     (a) a Bank or any holding company of such Bank is unable to obtain the rate
         of return on its capital pursuant to or in respect of this Agreement
         which it would have been able to obtain but for such reason;

     (b) a Bank or any holding company of such Bank incurs a cost as a result of
         such Bank's entering into or assuming or maintaining a commitment or
         performing its obligations (including its obligation to participate in
         the making of Advances) under this Agreement; or

     (c) there is any increase in the cost to a Bank or any holding company of
         such Bank of funding or maintaining all or any of the loans comprised
         in a class of loans formed by or including such Bank's share of the
         Advances,

then the Borrower shall, from time to time on demand of the Agent, promptly pay
to the Agent for the account of that Bank amounts sufficient to hold harmless
and indemnify that Bank or such Bank's holding company from and against, as the
case may be, (1) such reduction in the rate of return of capital, (2) such cost
and (3) such increased cost (or such proportion of such increased cost as is, in
the opinion of that Bank, attributable to its participating in the funding or
maintaining of Advances).

11.2 Increased Costs Claims  A Bank intending to make a claim pursuant to Clause
11.1 (Increased Costs) shall notify the Agent of the event by reason of which it
is entitled to do so (supported by any relevant calculations), whereupon the
Agent shall notify the Borrower thereof  Provided that nothing herein shall
require such Bank to disclose any confidential information relating to the
organisation of its affairs.

                                      -18-
<PAGE>
 
11.3 Illegality  If, at any time, it is unlawful for a Bank to make, fund or
allow to remain outstanding all or part of its share of the Advances, then that
Bank shall, promptly after becoming aware of the same, deliver to the Borrower
through the Agent a notice to that effect and:

     (a) such Bank shall not thereafter be obliged to participate in the making
         of any Advances and the amount of its Available Commitment shall be
         immediately reduced to zero; and

     (b) if the Agent on behalf of such Bank so requires, the Borrower shall on
         such date as the Agent shall have specified (which in any event shall
         be a date no later than legally permitted) repay such Bank's share of
         any outstanding Advances together with accrued interest thereon and all
         other amounts owing to such Bank hereunder.

11.4 Mitigation  If, in respect of any Bank, circumstances arise which would or
would upon the giving of notice result in:

     (a) an increase in the amount of any payment to be made to it for its
         account pursuant to Clause 9.1 (Tax Gross-Up); or

     (b) a claim for indemnification from the Borrower pursuant to Clause 9.2
         (Tax Indemnity) or Clause 11.1 (Increased Costs),

then such Bank shall, after consultation with the Agent and the Borrower and to
the extent that it can do so lawfully and without prejudice to its own position,
consider what steps it might reasonably take (including a change in its Facility
Office or the transfer of its rights, benefits and obligations hereunder to
another financial institution acceptable to the Borrower and willing to
participate in the Facility) with a view to mitigating the effect of such
circumstances on the Borrower.

such jurisdiction).

12.2 Powers  It has all corporate power and authority, governmental permits,

         Lease-Back Transaction secured by an encumbrance on the property to 
         be leased without equally and ratably securing the Loan; or

     (b) the Guarantor (and in any such case the Guarantor covenants to) within
         four months after the effective date of such Sale and Lease-Back

         Group), repays Indebtedness for Borrowed Money of the Borrower ranking
         at least pari passu with the Loan in an amount equal to the Value of
         such Sale and Lease-Back Transaction less the principal amount of such
         Indebtedness for Borrowed Money repaid within such four month period,
         excluding repayments of such Indebtedness for Borrowed Money as a
         result of conversions or pursuant to mandatory sinking fund or

         payment at maturity.

15.10  Transactions with Affiliates  The Guarantor shall ensure that no member
of the Group shall, directly or indirectly, pay any funds to or for the account
of, make any investment in (whether by acquisition of shares or indebtedness, by
loan, advance, transfer of property, guarantee or other agreement to pay,
purchase or service, directly or indirectly, any Indebtedness for Borrowed
Money, or otherwise), sell, lease, transfer or otherwise dispose of any assets,
tangible or intangible, to, or participate in or effect any transaction in
connection with any joint enterprise or other joint arrangement with, any
Affiliate  Provided that the foregoing shall not prohibit:

     (a) the Guarantor declaring or making a dividend or other distribution

         with any Affiliate if such sales, purchases or leases are made or such
         services are rendered or such member of the Group participates in the
         ordinary course of its business and in the aggregate during each
         financial year of the Guarantor, the terms and conditions of all such
         sales, purchases, leases, rendered services and participations are not
         materially less favourable to the similar transactions with persons who
         are not Affiliates;

     (e) any member of the Group making payments with respect to any
         Indebtedness for Borrowed Money of such member of the Group to any

         at the time of the creation of such Indebtedness for Borrowed Money
         from a lender who was not an Affiliate.

                        DEFAULT INTEREST AND INDEMNITY


18.   Default Interest and Indemnity

18.1  Default Interest Periods  If any sum due and payable by either of the
Obligors hereunder is not paid on the due date therefor in accordance with the
provisions of Clause 20 (Payments) or if any sum due and payable by either of
the Obligors under any judgment of any court in connection herewith is not paid
on the date of such judgment, the period beginning on such due date or, as the
case may be, the date of such judgment and ending on the date upon which the
obligation of such Obligor to pay such sum (the balance thereof for the time
being unpaid being herein referred to as an "unpaid sum") is discharged shall be
divided into successive periods, each of which (other than the first) shall
start on the last day of the preceding such period and the duration of each of
which shall (except as otherwise provided in this Clause 18) be selected by the
Agent.

18.2  Default Interest  During each such period relating thereto as is mentioned
in Clause 18.1 (Default Interest Periods) an unpaid sum shall bear interest at
the rate per annum which is the sum from time to time of one per cent., the

            and the rate per annum notified to the Agent by such Bank as soon as
            practicable after the beginning of such period as being that which
            expresses as a percentage rate per annum the cost to such Bank of
            funding from whatever sources it may select its portion of such
            unpaid sum during such period; and

      (b)   if such unpaid sum is all or part of an Advance which became due and
            payable on a day other than the last day of an Interest Period
            relating thereto, the first such period applicable thereto shall be
            of a duration equal to the unexpired portion of that Interest Period
            and the rate of interest applicable thereto from time to time during
            such period shall be that which exceeds by one per cent. the rate
            which would have been applicable to it had it not so fallen due.

18.3  Payment of Default Interest  Any interest which shall have accrued under
Clause 18.2 (Default Interest) in respect of an unpaid sum shall be due and
payable and shall be paid by the Obligor owing such unpaid sum at the end of the
period by reference to which it is calculated or on such other dates as the
Agent may specify by written notice to such Obligor.

18.4  Broken Periods  If any Bank or the Agent on its behalf receives or
recovers all or any part of such Bank's share of an Advance otherwise than on
the last day of an Interest Period relating to that Advance, the Borrower shall
pay to the Agent on demand for account of such Bank an amount equal to the
amount (if any) by which (a) the additional interest which would have been
payable on the amount so received or recovered had it been received or recovered
on the last day of that Interest Period exceeds (b) the amount of interest which
in the opinion of the Agent would have been payable to the Agent on the last day
of that Interest Period in respect of a Guilder deposit equal to the amount so
received or recovered placed by it with a prime bank in London for a period
starting on the third business day following the date of such receipt or
recovery and ending on the last day of that Interest Period Provided that such
Bank shall deliver to the Borrower, within sixty days of such receipt or
recovery, a certificate as to the amounts due pursuant to sub-paragraphs (a) and
(b) above and setting forth in reasonable detail the basis for such amount and
such certificate shall be conclusive in the absence of manifest error.

18.5  Borrower's Indemnity  The Borrower undertakes to indemnify:

      (a)   each of the Agent, the Arranger and the Banks against any cost,
            claim, loss, expense (including legal fees) or liability together
            with any VAT thereon, which any of them may sustain or incur
            (otherwise than by reason of its own gross negligence or wilful
            misconduct) as a consequence of the occurrence of any Event of
            Default or any default by the Borrower in the performance of any of
            the obligations expressed to be assumed by it in this Agreement; and

      (b)   each Bank against any loss it may suffer or incur (otherwise than by
            reason of its own gross negligence or wilful misconduct) as a result
            of its funding or making arrangements to fund its portion of an
            Advance requested by the Borrower hereunder but not made by reason
            of the operation of any one or more of the provisions hereof.

18.6  Unpaid Sums as Advances  Any unpaid sum shall (for the purposes of this
Clause 18 and Clause 11.1 (Increased Costs)) be treated as an advance and
accordingly in this Clause 18 and Clause 11.1 (Increased Costs)) the term
"Advance" includes any unpaid sum and the term "Interest Period", in relation to
an unpaid sum, includes each such period relating thereto as is mentioned in
Clause 18.1 (Default Interest Periods).

19.   Currency of Account and Payment

19.1  Currency of Account  The Guilder is the currency of account and payment
for each and every sum at any time due from either of the Obligors hereunder
Provided that:

      (a)   each payment in respect of costs and expenses shall be made in the
            currency in which the same were incurred; and

      (b)   each payment pursuant to Clause 9.2 (Tax Indemnity) or Clause 11.1
            (Increased Costs) shall be made in the currency specified by the
            party claiming thereunder.

19.2  Currency Indemnity  If any sum due from either of the Obligors under this
Agreement or any order or judgment given or made in relation hereto has to be
converted from the currency (the "first currency") in which the same is payable
hereunder or under such order or judgment into another currency (the "second
currency") for the purpose of (a) making or filing a claim or proof against such
Obligor, (b) obtaining an order or judgment in any court or other tribunal or
(c) enforcing any order or judgment given or made in relation hereto, the
Borrower shall indemnify and hold harmless each of the persons to whom such sum
is due from and against any loss suffered or incurred as a result of any
discrepancy between (i) the rate of exchange used for such purpose to convert
the sum in question from the first currency into the second currency and (ii)
the rate or rates of exchange at which such person may in the ordinary course of
business purchase the first currency with the second currency upon receipt of a
sum paid to it in satisfaction, in whole or in part, of any such order,
judgment, claim or proof.

20.   Payments

20.1  Payments to the Agent  On each date on which this Agreement requires an
amount denominated in Guilders to be paid by either of the Obligors or any of
the Banks hereunder, such Obligor or, as the case may be, such Bank shall make
the same available to the Agent by payment in Guilders and in immediately
available, freely transferable, cleared funds to such account with such bank as
the Agent shall have specified for this purpose.

20.2  Alternative Payment Arrangements  If, at any time, it shall become
impracticable (by reason of any action of any governmental authority or any
change in law, exchange control regulations or any similar event) for either or
both of the Obligors to make any payments hereunder in the manner specified in
Clause 20.1 (Payments to the Agent), then such Obligor may agree with each or
any of the Banks alternative arrangements for the payment direct to such Bank of
amounts due to such Bank hereunder  Provided that, in the absence of any such
agreement with any Bank, such Obligor shall be obliged to make all payments due
to such Bank in the manner specified herein.  Upon reaching such agreement such
Obligor and such Bank shall immediately notify the Agent thereof and shall
thereafter promptly notify the Agent of all payments made direct to such Bank.

20.3  Payments by the Agent  Save as otherwise provided herein, each payment
received by the Agent for the account of another person pursuant to Clause 20.1
(Payments to the Agent) shall be made available by the Agent to such other
person (in the case of a Bank, for the account of its Facility Office) for value
the same day

                                      -39-
<PAGE>
 
by transfer to such account of such person with such bank in the principal
financial centre of the country of the currency of such payment as such person
shall have previously notified to the Agent.

20.4  No Set-off  All payments required to be made by either of the Obligors
hereunder shall be calculated without reference to any set-off or counterclaim
and shall be made free and clear of and without any deduction for or on account
of any set-off or counterclaim.

20.5  Clawback  Where a sum is to be paid hereunder to the Agent for account of
another person, the Agent shall not be obliged to make the same available to
that other person until it has been able to establish to its satisfaction that
it has actually received such sum, but if it does so and it proves to be the
case that it had not actually received such sum, then the person to whom such
sum was so made available shall on request refund the same to the Agent together
with an amount sufficient to indemnify the Agent against any cost or loss it may
have suffered or incurred by reason of its having paid out such sum prior to its
having received such sum.

21.   Set-Off

21.1  Contractual Set-off Each  of the Obligors authorises each Bank to apply
any credit balance to which such Obligor is entitled on any account of such
Obligor with that Bank in satisfaction of any sum due and payable from such
Obligor to such Bank hereunder but unpaid; for this purpose, each Bank is
authorised to purchase with the moneys standing to the credit of any such
account such other currencies as may be necessary to effect such application.

21.2  Set-off not Mandatory No  Bank shall be obliged to exercise any right
given to it by Clause 21.1 (Contractual Set-off).

22.   Sharing

22.1  Redistribution of Payments  Subject to Clause 22.3 (Recoveries Through
Legal Proceedings), if at any time, the proportion which any Bank (a "Recovering
Bank") has received or recovered (whether by payment, the exercise of a right of
set-off or combination of accounts or otherwise) in respect of its portion of
any payment (a "relevant payment") to be made under this Agreement by either of
the Obligors for account of such Recovering Bank and one or more other Banks is
greater (the portion of such receipt or recovery giving rise to such excess
proportion being herein called an "excess amount") than the proportion thereof
so received or recovered by the Bank or Banks so receiving or recovering the
smallest proportion thereof, then:

      (a)   such Recovering Bank shall inform the Agent of such receipt or
            recovery and pay to the Agent an amount equal to such excess amount;

      (b)   there shall thereupon fall due from such Obligor to such Recovering
            Bank an amount equal to the amount paid out by such Recovering Bank
            pursuant to paragraph (a) above, the amount so due being, for the
            purposes hereof, treated as if it were an unpaid part of such
            Recovering Bank's portion of such relevant payment; and

                                      -40-
<PAGE>
 
      (c)   the Agent shall treat the amount received by it from such Recovering
            Bank pursuant to paragraph (a) above as if such amount had been
            received by it from such Obligor in respect of such relevant payment
            and shall pay the same to the persons entitled thereto (including
            such Recovering Bank) pro rata to their respective entitlements
            thereto.

22.2  Repayable Recoveries  If any sum (a "relevant sum") received or recovered
by a Recovering Bank in respect of any amount owing to it by either of the
Obligors becomes repayable and is repaid by such Recovering Bank, then:

      (a)   each Bank which has received a share of such relevant sum by reason
            of the implementation of Clause 22.1 (Redistribution of Payments)
            shall, upon request of the Agent, pay to the Agent for account of
            such Recovering Bank an amount equal to its share of such relevant
            sum; and

      (b)   there shall thereupon fall due from such Obligor to each such Bank
            an amount equal to the amount paid out by it pursuant to paragraph
            (a) above, the amount so due being, for the purposes hereof, treated
            as if it were the sum payable to such Bank against which such Bank's
            share of such relevant sum was applied.

22.3  Recoveries Through Legal Proceedings  If any Bank shall commence any
action or proceeding in any court to enforce its rights hereunder after
consultation with the other Banks and, as a result thereof or in connection
therewith, shall receive any excess amount (as defined in Clause 22.1
(Redistribution of Payments)), then such Bank shall not be required to share any
portion of such excess amount with any Bank which has the legal right to, but
does not, join in such action or proceeding or commence and diligently prosecute
a separate action or proceeding to enforce its rights in another court.

Available Facility) for the time being (or, if the Loan has been repaid in full,

25.   The Agent, the Arranger and the Banks

25.1  Appointment of the Agent  The Arranger and each Bank hereby appoints the
Agent to act as its agent in connection herewith and authorises the Agent to
exercise such rights, powers, authorities and discretions as are specifically
delegated to the Agent by the terms hereof together with all such rights,
powers, authorities and discretions as are reasonably incidental thereto.  The
Agent is not a trustee and owes no fiduciary obligations to any other party to
this Agreement.

25.2  Agent's Discretions  The Agent may:

      (a)   assume, unless it has, in its capacity as agent for the Banks,
            received notice to the contrary from any other party hereto (or, in
            the case of a payment default, actual knowledge to the contrary),
            that (i) any representation made by either of the Obligors in
            connection herewith is true, (ii) no Event of Default or Potential
            Event of Default has occurred, (iii) neither of the Obligors is in
            breach of or default under its obligations hereunder and (iv) any
            right, power, authority or discretion vested herein upon an
            Instructing Group, the Banks or any other person or group of persons
            has not been exercised;

      (b)   assume that the Facility Office of each Bank is that identified with
            its signature below (or, in the case of a Transferee, at the end of
            the Transfer Certificate to which it is a party as Transferee) until
            it has received from such Bank a notice designating some other
            office of such Bank to replace its Facility Office and act upon any
            such notice until the same is superseded by a further such notice;

      (c)   engage and pay for the advice or services of any lawyers,
            accountants, surveyors or other experts whose advice or services may
            to it seem necessary, expedient or desirable and rely upon any
            advice so obtained;

      (d)   rely as to any matters of fact which might reasonably be expected to
            be within the knowledge of either of the Obligors upon a certificate
            signed by or on behalf of such Obligor;

      (e)   rely upon any communication or document believed by it to be
            genuine;

      (f)   refrain from exercising any right, power or discretion vested in it
            as agent hereunder unless and until instructed by an Instructing
            Group as to whether or not such right, power or discretion is to be
            exercised and, if it is to be exercised, as to the manner in which
            it should be exercised; and

      (g)   refrain from acting in accordance with any instructions of an
            Instructing Group to begin any legal action or proceeding arising
            out of or in connection with this Agreement until it shall have
            received such security as it may require (whether by way of payment
            in advance or otherwise) for all costs, claims, losses, expenses
            (including legal fees) and liabilities together

                                      -43-

            with any VAT thereon which it will or may expend or incur in
            complying with such instructions.

25.3  Agent's Obligations  The Agent shall:

      (a)   promptly inform each Bank of the contents of any notice or document

      (b)   promptly notify each Bank of the occurrence of any Event of Default
            or any default by either of the Obligors in the due performance of
            or compliance with its obligations under this Agreement of which the
            Agent has notice from any other party hereto (or, in the case of a
            payment default, actual knowledge);

      (c)   save as otherwise provided herein, act as agent hereunder in
            accordance with any instructions given to it by an Instructing
            Group, which instructions shall be binding on the Arranger and the
            Banks; and

      (d)   if so instructed by an Instructing Group, refrain from exercising
            any right, power or discretion vested in it as agent hereunder.

25.4  Excluded Obligations  Notwithstanding anything to the contrary expressed
or implied herein, neither the Agent nor the Arranger shall:

      (a)   be bound to enquire as to (i) whether or not any representation made
            by either of the Obligors in connection herewith is true, (ii) the
            occurrence or otherwise of any Event of Default or Potential Event
            of Default, (iii) the performance by either of the Obligors of its
            obligations hereunder or (iv) any breach of or default by either of
            the Obligors of or under its obligations hereunder;

      (b)   be bound to account to any Bank for any sum or the profit element of
            any sum received by it for its own account;

      (c)   be bound to disclose to any other person any information relating to
            any member of the Group or anyone else if such disclosure would or
            might in its opinion constitute a breach of any law or regulation or
            be otherwise actionable at the suit of any person; or

      (d)   be under any obligations other than those for which express
            provision is made herein.

25.5  Delegation  The Agent may delegate, transfer or assign to any subsidiary
of The Chase Manhattan Corporation or its Successor from time to time all or any
of the rights, powers, authorities and discretions vested in it hereunder and
the performance of its duties in accordance herewith, and such delegation,
transfer or assignment may be made upon such terms and subject to such
conditions (including the power to sub-delegate) and subject to such regulations
as the Agent may think fit (and the term "Agent" as used in this Agreement shall
include any such delegate, transferee or assignee).

                                      -44-
<PAGE>
 
25.6  Indemnification  Each Bank shall, from time to time on demand by the
Agent, indemnify the Agent, in the proportion its share of the Loan (or, if no
Advances have been made, its Available Commitment) bears to the amount of the
Loan (or, if no Advances have been made, the Available Facility) at the time of
such demand (or, if the Loan has then been repaid in full, immediately prior to
the final repayment thereof), against any and all costs, claims, losses,
expenses (including legal fees) and liabilities together with any VAT thereon
which the Agent may incur, otherwise than by reason of (a) its own gross
negligence or wilful misconduct, in acting in its capacity as agent hereunder or
(b) the failure of the Borrower to pay to the Agent the agency fees referred to
in Clause 23.2 (Agency Fee).

25.7  Exclusion of Liabilities  Neither the Agent nor the Arranger accepts any
responsibility for the accuracy and/or completeness of the Information
Memorandum or any other information supplied by either of the Obligors in
connection herewith or for the legality, validity, effectiveness, adequacy or
enforceability of this Agreement and neither the Agent nor the Arranger shall be
under any liability as a result of taking or omitting to take any action in
relation to this Agreement, save in the case of gross negligence or wilful
misconduct.

25.8  No Actions  Each of the Banks agrees that it will not assert or seek to
assert against any director, officer or employee of the Agent or the Arranger
any claim it might have against any of them but which it could not bring
successfully against the Agent or the Arranger.

25.9  Business with the Group and others  The Agent (whether acting through its
agency division or otherwise) and the Arranger may accept deposits from, lend
money to and generally engage in any kind of banking or other business with any
member of the Group whether or not it may or does lead to a conflict with the
interests of any Bank and the Agent or the Arranger may undertake business with
or for others even though it may or does lead to a conflict with the interests
of any Bank.

25.10 Resignation  The Agent may resign its appointment hereunder at any time
without assigning any reason therefor by giving not less than thirty days' prior
written notice to that effect to each of the other parties hereto  Provided that
no such resignation shall be effective until either:

      (a)   the Agent appoints as its Successor any subsidiary or holding
            company, or any subsidiary of any holding company, of the Agent; or

      (b)   a Successor for the Agent is appointed in accordance with the
            succeeding provisions of this Clause 25.

25.11 Successor Agent  If the Agent gives notice of its resignation pursuant to
Clause 25.10 (Resignation), then any reputable and experienced bank or other
financial institution may be appointed as a Successor to the Agent by an
Instructing Group with the consent of the Borrower (such consent not to be
unreasonably withheld) during the period of such notice but, if no such
Successor is so appointed within 30 days after the expiry of such notice, the
Agent may appoint such a Successor itself with the consent of the Borrower (such
consent not to be unreasonably withheld).

25.12 Rights and Obligations  If a Successor to the Agent is appointed under
the provisions of Clause 25.11 (Successor Agent), then (a) the retiring Agent
shall be discharged from any further obligation hereunder but shall remain
entitled to the benefit of the provisions of this Clause 25 and (b) its
Successor and each of the other parties hereto shall have the same rights and
obligations amongst themselves as they would have had if such Successor had been
a party hereto.

                                      -45-

25.13 Own Responsibility  It is understood and agreed by each Bank that it has
itself been, and will continue to be, solely responsible for making its own
independent appraisal of and investigations into the financial condition,
creditworthiness, condition, affairs, status and nature of each member of the
Group and, accordingly, each Bank warrants to the Agent and the Arranger that it
has not relied on and will not hereafter rely on the Agent and the Arranger or
any of them:

      (a)   to check or enquire on its behalf into the adequacy, accuracy or
            completeness of any information provided by either of the Obligors
            in connection with this Agreement or the transactions herein
            contemplated (whether or not such information has been or is
            hereafter circulated to such Bank by the Agent and the Arranger or
            any of them); or

      (b)   to assess or keep under review on its behalf the financial
            condition, creditworthiness, condition, affairs, status or nature of
            any member of the Group.

25.14 Agency Division Separate  In acting as agent for the Arranger and the
Banks, the agency division of the Agent shall be treated as if it were a legal
entity separate from all its other divisions and departments ("elsewhere").
Accordingly, any information or documents received elsewhere is not, by reason
of such receipt, to be treated as having been received by the agency division,
and all business undertaken elsewhere is not to be treated as having been
undertaken by the agency division.  The agency division of the Arranger shall be
treated in this same manner as a legal entity separate from all its other
divisions and departments.

25.15 Confidential Information  Notwithstanding anything to the contrary
expressed or implied herein and without prejudice to the provisions of Clause
25.14 (Agency Division Separate), the Agent shall not be bound to disclose to

26.   Assignments and Transfers

26.1  Binding Agreement  This Agreement shall be binding upon and enure to the
benefit of each party hereto and its or any subsequent Successors, Transferees
and assigns.

26.2  Assignments and Transfers by the Obligors  Each of the Obligors shall only
be entitled to assign or transfer all or any of its rights, benefits and
obligations hereunder with the prior written consent of the Agent and all the
Banks.

26.3  Assignments and Transfers by Banks  Any Bank may, at any time, assign or
transfer all or any of its rights and benefits hereunder or transfer in
accordance with Clause 26.5 (Transfers by Banks) all or any of its rights,
benefits and obligations hereunder to:

      (i)   any affiliate of such Bank (for the purposes of this Clause
            "affiliate" means (a) any person which controls directly or
            indirectly the Bank or (b) any person which is controlled by or is
            under common control with a person which controls, directly or
            indirectly, the Bank); or

      (ii)  with the prior consent of the Borrower (such consent not to be
            unreasonably withheld), any other person.

26.4  Assignments by Banks  If any Bank assigns all or any of its rights and
benefits hereunder in accordance with Clause 26.3 (Assignments and Transfers by
Banks), then, unless and until the assignee has agreed with the Agent, the
Arranger and the other Banks that it shall be under the same obligations towards
each of them as it would have been under if it had been an original party hereto
as a Bank (whereupon such assignee shall become a party hereto as a "Bank"), the
Agent, the Arranger and the other Banks shall not be obliged to recognise such
assignee as having the rights against each of them which it would have had if it
had been such a party hereto.

26.5  Transfers by Banks  If any Bank wishes to transfer all or any of its
rights, benefits and/or obligations hereunder as contemplated in Clause 26.3
(Assignments and Transfers by Banks), then such transfer may be effected by the
delivery to the Agent of a duly completed and duly executed Transfer Certificate
in which event, on the later of the Transfer Date specified in such Transfer
Certificate and the fifth business day after (or such earlier business day
endorsed by the Agent on such Transfer Certificate falling on or after) the date
of delivery of such Transfer Certificate to the Agent:

      (a)   to the extent that in such Transfer Certificate the Bank party
            thereto seeks to transfer its rights, benefits and obligations
            hereunder, each of the Obligors and such Bank shall be released from
            further obligations towards one another hereunder and their
            respective rights against one another shall be cancelled (such
            rights and obligations being referred to in this Clause 26.5 as
            "discharged rights and obligations");

                                      -47-
<PAGE>
 
      (b)   each of the Obligors and the Transferee party thereto shall assume
            obligations towards one another and/or acquire rights against one
            another which differ from such discharged rights and obligations
            only insofar as such Obligor and such Transferee have assumed and/or
            acquired the same in place of such Obligor and such Bank;

      (c)   the Agent, the Arranger, such Transferee and the other Banks shall
            acquire the same rights and benefits and assume the same obligations
            between themselves as they would have acquired and assumed had such
            Transferee been an original party hereto as a Bank with the rights,
            benefits and/or obligations acquired or assumed by it as a result of
            such transfer; and

      (d)   such Transferee shall become a party hereto as a "Bank".

26.6  Changes in Circumstances  No assignee or Transferee of a Bank's rights may
receive any greater payment under Clause 9 (Taxes) or Clause 11 (Changes in
Circumstances) than such Bank would have been entitled to receive with respect
to the rights assigned or transferred unless such transfer is (a) made with the
prior written consent of the Borrower or (b) made to either (i) a Bank already
party to this Agreement at the time of such assignment or transfer or (ii) an
affiliate of the transferor Bank.

26.7  Transfer Fees  On the date upon which a transfer takes effect pursuant to
Clause 26.5 (Transfers by Banks) the Transferee in respect of such transfer
shall pay to the Agent for its own account a transfer fee of $1000 (or its
Equivalent Amount).

26.8  Disclosure of Information  Any Bank may disclose to any actual or
potential assignee or Transferee or to any person who may otherwise enter into
contractual relations with such Bank in relation to this Agreement such
information about the Obligors and the Group as such Bank shall consider
appropriate.

time due from the Borrower hereunder or the amount which, but for any of the
obligations of the Borrower hereunder being or becoming void, voidable,

                               THE FIFTH SCHEDULE

                       Opinion of the Guarantor's Counsel

March     , 1997

To:  Chase Manhattan International Limited as Agent on its own behalf and for
     and on behalf of the Arranger and the Banks referred to in the Facility
     Agreement (described below)


Re:  NLG300,000,000 Term Loan Facility

Ladies and Gentlemen:

We have acted as counsel to ARCO Chemical Company, a Delaware corporation (the
"Guarantor") and ARCO Chemie Nederland, Ltd., a Delaware corporation (the
"Borrower") in connection with that certain NLG300,000,000 Term Loan Facility,
dated March __, 1997 (the "Facility Agreement") among the Borrower, the Company
as Guarantor, Chase Investment Bank Limited as Arranger, Chase Manhattan
International Limited as Agent, and the financial institutions defined therein
as Banks.  Except as otherwise provided herein, terms defined in the Facility
Agreement are used herein as defined therein.  This opinion letter is being
delivered pursuant to Clause 2.3 of the Facility Agreement.

In rendering the opinions expressed below, we have examined the Facility
Agreement, the Certificate of Incorporation and Bylaws of each of the Guarantor
and the Borrower and such records of each of the Guarantor and the Borrower and
such other documents as we have deemed necessary as a basis for such opinions.

In our examination, we have assumed the genuineness of all signatures (other
than those of the Guarantor and the Borrower), the authenticity of all documents
submitted to us as originals and the conformity with authentic original
documents of all documents submitted to us as copies.  As to matters of fact, we
have relied upon statements of governmental officials and upon representations
made in or pursuant to the Facility Agreement and certificates of appropriate
representatives of the Guarantor and the Borrower.

Based upon and subject to the foregoing and subject also to the comments and
qualifications set forth below, and having considered such questions of law as
we have deemed necessary as a basis for the opinions expressed below, we are of
the opinion that:

1.   Each of the Guarantor and the Borrower is a corporation validly existing
     and in good standing under the laws of the State of Delaware.

2.   Each of the Guarantor and the Borrower has all necessary corporate power
     and authority to execute and deliver the Facility Agreement and to perform
     its respective obligations thereunder, and all necessary corporate action
     on the part of each of the Guarantor and the Borrower has been taken to
     authorize such execution, delivery and performance.

                                      -61-
<PAGE>
 
3.   The Facility Agreement has been duly authorised executed and delivered by
     each of the Guarantor and the Borrower and constitutes the legal, valid and
     binding obligation of each of the Guarantor and the Borrower, enforceable
     against such parties in accordance with its terms, except as may be limited
     by bankruptcy, insolvency, reorganization, moratorium or other similar laws
     relating to or affecting the rights of creditors generally and except as
     the enforceability of the Facility Agreement is subject to the application
     of general principles of equity (regardless of whether considered in a
     proceeding in equity or at law), including, without limitation (a) the
     availability of specific performance, injunctive relief or any other
     equitable remedy and (b) concepts of materiality, reasonableness, good
     faith and fair dealing.

4.   No approval, consent, order, authorization, permit, license, exemption of,
     or registration, declaration or filing with, any federal, state or local
     governmental, regulatory or public agency, authority or court is required
     in connection with the execution, delivery and performance by each of the
     Guarantor and the Borrower of its respective obligations under the Facility
     Agreement.

5.   Except as may be limited by the Uniform Foreign Money Judgment Recognition
     Act as in effect in the Commonwealth of Pennsylvania, a judgment for the
     recovery of money due and owing under the Facility Agreement in the English
     courts would be enforceable in the courts of the Commonwealth of
     Pennsylvania in the same manner as a judgment obtained in a court of
     appropriate jurisdiction in the United States of America.

The foregoing opinions are subject to the following comments and qualifications:

(A)  The enforceability of provisions of the Facility Agreement requiring the
     Borrower or the Guarantor to indemnify any other party may be limited by
     (i) laws rendering unenforceable indemnification contrary to Federal or
     state securities laws and the public policy underlying such laws and (ii)
     laws limiting the enforceability of provisions exculpating or exempting a
     party, or requiring indemnification of a party for, liability for its own
     action or inaction, to the extent the action or inaction involves gross
     negligence, recklessness, wilful misconduct or unlawful conduct.

(B)  The enforceability of provisions in the Facility Agreement to the effect
     that terms may not be waived or modified except in writing may be limited
     under certain circumstances.

(C)  We express no opinion as to (i) the effect of the laws of any jurisdiction
     in which any Bank is located that limit the interest, fees or other charges
     such Bank may impose, (ii) clause 31 of the Facility Agreement.

(D)  We assume that the Facility Agreement is the legal, valid and binding
     obligation of each party thereto other than the Guarantor and the Borrower.

We are licensed to practice law in the Commonwealth of Pennsylvania and have not
in connection with this opinion made an investigation of the laws of any other
jurisdiction except the federal laws of the United States and the General
Corporation Law of the State of Delaware and nothing in this opinion should be
or shall be construed otherwise.  This opinion is limited solely to the laws of
the Commonwealth of Pennsylvania, the General Corporation Law of the State of
Delaware and the federal laws of the United States and rules, regulations and
orders thereunder which are presently in effect.

                                      -62-
<PAGE>
 
This opinion is given as of the date hereof, is given for the benefit of the
Arranger and the Banks and the benefit of your counsel, and may not be relied
upon by any other person or entity.

Very truly yours,

                                      -63-

A Money Market Quote may set forth up to five separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation

     (iii)  Any Money Market Quote shall be disregarded that:

     specify all of the information required by subsection (d)(ii) of this
     Section;

          (B)   contains qualifying, conditional or similar language;

          (C)   proposes terms other than or in addition to those set forth in

modifies or is otherwise inconsistent with a previous

                                      17
<PAGE>
 
Money Market Quote submitted by such Bank with respect to the same Money Market
Quote Request; provided that any such subsequent Money Market Quote shall be

disregarded by the Agent unless such subsequent Money Market Quote is submitted
solely to correct a manifest error in such former Money Market Quote.  The
Agent's notice to the Borrower shall specify (x) the aggregate principal amount
and currency of Money Market Loans for which offers have been received for each
Interest Period specified in the related Money Market Quote Request, (y) the
respective principal amounts and Money Market Margins or Money Market Rates, as
the case may be, so offered and (z) if applicable, limitations on the aggregate
principal amount of Money Market Loans for which offers in any single Money
Market Quote may be accepted.

     (f)  Not later than (x) 5:00 p.m., London time, on the fourth Euro-Currency
business Day prior to the proposed date of Borrowing, in the case of a LIBOR
Auction in a Designated Currency other than Dollars, (y) 10:00 a.m., Chicago
time, on the third Euro-Currency Business Day prior to the proposed date of
Borrowing, in the case of a LIBOR Auction in Dollars, or (z) 10:00 a.m., Chicago

(or, in any such case, such other time and date as the Borrower and the Agent
shall have mutually agreed upon and shall have notified the Banks of not later
than the date of the Money Market Quote Request for the first LIBOR Auction or
Absolute Rate Auction for which such change is to be effective), the Borrower
shall notify the Agent of its acceptance or non-acceptance of the offers so
notified to it pursuant to subsection (e) of this Section.  In the case of
acceptance, such notice (a "Notice of Money Market Borrowing") shall specify the
aggregate principal amount of offers for each Interest Period that are accepted.
The Borrower may accept any Money Market Quote in whole or in part; provided
                                                                    --------
that:

          (i)   the aggregate principal amount of each Money Market Borrowing
     may not exceed the applicable amount set forth in the related Money Market
     Quote Request;

          (ii)  the principal amount of each Money Market Borrowing must be at
     least $10,000,000 (or the Approximate Equivalent Amount thereof) or a
     larger multiple of $1,000,000 (or the Approximate Equivalent Amount
     thereof); provided that upon giving effect to such Borrowing, the then
               --------                                                    
     aggregate outstanding principal Dollar Amount of all Syndicated Loans and
     all Money Market Loans shall not exceed the aggregate amount of the
     Commitments then in effect;

          (iii) acceptance of offers for each Interest Period may only be made
     on the basis of ascending Money Market Margins or Money Market Rates, as
     the case may be; and

          (iv)  the Borrower may not accept any offer that is described in
     subsection (d)(iii) of this Section or that otherwise fails to comply with
     the requirements of this Agreement.

     (g)  If offers are made by two or more Banks with the same Money Market
Margins or Money Market Rates, as the case may be, for a greater aggregate
principal amount of Money Market Loans than can be accepted for the related
Interest Period (after giving effect to the acceptance of all lower

                                      18
<PAGE>
 
Money Market Margins or Money Market Rates, as the case may be, properly offered
for such Interest Period), the principal amount of Money Market Loans which can
be accepted shall be allocated by the Agent among such Banks as nearly as
possible (in such multiples, not greater than $1,000,000 (or the Approximate
Equivalent Amount thereof), as the Agent may deem appropriate) in proportion to
the aggregate principal amount of such offers.  Determinations by the Agent of
the amounts of Money Market Loans by each Bank shall be conclusive in the
absence of manifest error.

     SECTION 2.04.  Notice to Banks; Funding of Loans. (a) Upon receipt of a
                    ---------------------------------                       
Notice of Borrowing, the Agent shall promptly notify each Bank of the contents
thereof and of such Bank's ratable share (if any) of such Borrowing and such
Notice of Borrowing shall not thereafter be revocable by the Borrower except
pursuant to subsection (d) of this Section or Section 8.01(a).

     (b)  On the date of each Borrowing, each Bank participating therein shall
(except as provided in subsection (c) of this Section) make available its
ratable share of such Borrowing, (i) if such Borrowing is denominated in
Dollars, not later than 12:00 noon, Chicago time, in Federal or other funds
immediately available to the Agent, in Chicago, Illinois at its address
specified in or pursuant to Section 10.01 and, (ii) if such Borrowing is
denominated in another currency, not later than 12:00 noon, local time in the
city of the Agent's Euro-Currency Payment Office for such currency, in such
funds as may then be customary for the settlement of international transactions
in such currency in the city of and at the address of the Agent's Euro-Currency
Payment Office for such currency. Unless the Agent determines that any
applicable condition specified in Article III has not been satisfied, the Agent
will make the funds so received from the Banks available to the Borrower at the
Agent's aforesaid address.

     (c)  If any Bank makes a new Loan hereunder on the date on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank,
which outstanding Loan is denominated in the currency of such new Loan, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the principal amount being repaid shall be made available by such Bank to the
Agent as provided in subsection (b) of this Section or remitted by the Borrower
to the Agent as provided in Section 2.12, as the case may be.

     (d)  Notwithstanding the satisfaction of all conditions referred to in
Section 2.01, 2.02 or 2.03(b) with respect to any Borrowing in any currency
other than Dollars, if there shall occur on or prior to the date of such
Borrowing any change in national or international financial, political or
economic conditions or currency exchange rates or exchange controls which would
in the opinion of the Agent or the Required Banks make it impracticable for the
Euro-Currency Loans or Money Market LIBOR Loans comprising such Borrowing to be
denominated in the currency specified by the Borrower, then the Agent shall
forthwith give notice thereof to the Borrower and the Banks, and such Loans
shall not be denominated in such currency but shall be made on the date of such
Borrowing in Dollars, in an aggregate principal amount equal to the Dollar
Amount of the aggregate principal amount specified in the related Notice of
Borrowing, as Base Rate Loans, unless the Borrower notifies the Agent at least
one Domestic Business Day before such date that (i) it elects

                                      19
<PAGE>
 
not to borrow on such date or (ii) it elects to borrow on such date in a
different Agreed Currency or Designated Currency, as the case may be, in which
the denomination of such Loans would in the opinion of the Agent and the
Required Banks be practicable and in an aggregate principal amount equal to the
Dollar Amount of the aggregate principal amount specified in the related Notice
of Borrowing.

     SECTION 2.05.  Notes.  (a) The Loans of each Bank to the Borrower shall be
                    -----                                                      
evidenced by a single Note of the Borrower payable to the order of such Bank for
the account of its Applicable Lending Office in an amount equal to the aggregate
unpaid principal amount of such Bank's Loans to the Borrower.

     (b)  Each Bank may, by notice to the Borrower and the Agent (to be given
not later than two Domestic Business Days prior to the first Borrowing) request
that its Loans of a particular type be evidenced by a separate Note in an amount
equal to the aggregate unpaid principal amount of such Loans.  Each such Note
shall be in substantially the form of Exhibit A hereto with appropriate
modifications to reflect the fact that it evidences solely Loans of the relevant
type.  Each reference in this Agreement to a "Note" or the "Notes" of such Bank
shall be deemed to refer to and include any or all of such Notes, as the context
may require.

     (c)  Upon receipt of each Bank's Note(s) pursuant to Section 3.01(vi), the
Agent shall mail such Note(s) to such Bank.  Each Bank shall record, and prior
to any transfer of its Note(s) shall endorse on the schedules forming a part
thereof appropriate notations to evidence, the date, currency, amount and
maturity of each Loan made by it to the Borrower and the date and amount of each
payment of principal made by the Borrower with respect thereto; provided that
                                                                --------     
the failure of any Bank to make any such recordation or endorsement shall not
affect the obligations of the Borrower hereunder or under the Notes.  Each Bank
is hereby irrevocably authorized by the Borrower so to endorse the Notes and to
attach to and make a part of any such Note a continuation of any such schedule
as and when required.

     SECTION 2.06.  Maturity of Loans.  Each Loan included in any Borrowing
                    -----------------                                      
shall mature, and the principal amount thereof shall be due and payable, on the
last day of the Interest Period applicable to such Borrowing.

     SECTION 2.07.  Interest Rates.  (a) Each Base Rate Loan shall bear interest
                    --------------                                              
on the outstanding principal amount thereof, for each day from the date such
Loan is made until it becomes due at a rate per annum equal to the Base Rate for
such day.  Such interest shall be payable for each Interest Period on the last
day thereof.  Any overdue principal of and, to the extent permitted by law,
overdue interest on any Base Rate Loan shall bear interest, payable on demand,
for each day until paid at a rate per annum equal to the sum of 1% plus the rate
otherwise applicable to Base Rate Loans for such day.

     (b)  Each Euro-Currency Loan shall bear interest on the outstanding
principal amount thereof, for the Interest Period applicable thereto, at a rate
per annum equal to the sum of the applicable

                                      20
<PAGE>
 
Syndicated Margin plus the applicable London Interbank Offered Rate.  Such
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

     The "London Interbank Offered Rate" applicable to any Interest Period for
any Euro-Currency Loan or Money Market LIBOR Loan shall mean the average
(rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective
rates per annum at which deposits in the currency in which such Euro-Currency
Loan or Money Market LIBOR Loan is denominated are offered to each of the
Reference Banks in the London interbank market at approximately 11:00 a.m.,
London time, two Euro-Currency Business Days before the first day of such
Interest Period, in an amount approximately equal to (i) the principal amount of
the Euro-Currency Loan or Money Market LIBOR Loan of such Reference Bank to
which such Interest Period is to apply or (ii) if such Reference Bank is not
submitting a Money Market Quote for such Money Market LIBOR Loan, $10,000,000
(or the Approximate Equivalent Amount thereof), and for a period of time
comparable to such Interest Period; provided that (i) for Euro-Currency Loans
                                    --------                                 
denominated in pounds sterling the respective rates per annum at which deposits
in pounds sterling are offered to each of the Reference Banks shall be the rate
for euro-sterling deposits not domestic sterling deposits and (ii) for Money
Market LIBOR Loans denominated in pounds sterling the respective rates per annum
at which deposits in pounds sterling are offered to each of the Reference Banks
shall be the rates for euro-sterling or domestic sterling deposits as specified
by the Borrower in the relevant Money Market Quote Request.

     (c)  Any overdue principal of and, to the extent permitted by law, overdue
interest on any Euro-Currency Loan shall bear interest, payable on demand, for
each day from and including the date payment thereof was due to but excluding
the date of actual payment, at a rate per annum equal to the sum of 1% plus the
applicable Syndicated Margin plus the average (rounded upward, if necessary, to
the next higher 1/16 of 1%) of the respective rates per annum at which one day
(or, if such amount due remains unpaid more than three Euro-Currency Business
Days, then for such other period of time not longer than three months as the
Agent may elect) deposits in the relevant currency in an amount approximately
equal to such overdue payment due to each of the Reference Banks are offered to
such Reference Bank in the London interbank market for the applicable period
determined as provided above (or, if the circumstances described in clause (a)
or (b) of Section 8.01 shall exist, at a rate per annum equal to the sum of (i)
if such Euro-Currency Loan is denominated in Dollars, 1% plus the rate
applicable to Base Rate Loans for such day and (ii) if such Euro-Currency Loan
is denominated in any other currency, 1% plus the cost to such Bank of funding
or maintaining such Euro-Currency Loan).  The certificate of such Bank as to the
cost of funding or maintaining such Euro-Currency Loan shall be conclusive
absent manifest error.

     (d)  Subject to Section 8.01(a)(1), each Money Market LIBOR Loan shall bear
interest on the outstanding principal amount thereof, for the Interest Period
applicable thereto, at a rate per annum equal to the sum of the London Interbank
Offered Rate for such Interest Period (determined in accordance with subsection
(c) of this Section as if each Reference Bank were to participate in the related
Money Market Borrowing ratably in proportion to its Commitment) plus (or minus)
the

                                      21
<PAGE>
 
Money Market Margin quoted by the Bank making such Loan in accordance with
Section 2.03.  Each Money Market Rate Loan shall bear interest on the
outstanding principal amount thereof, for the Interest Period applicable
thereto, at a rate per annum equal to the Money Market Rate quoted by the Bank
making such Loan in accordance with Section 2.03.  Such interest shall be
payable for each Interest Period on the last day thereof.  Any overdue principal
of and, to the extent permitted by law, overdue interest on any Money Market
Loan shall bear interest, payable on demand, for each day until paid at a rate
per annum equal to the sum of (i) if such Money Market Loan is denominated in
Dollars, 1% plus the rate applicable to Base Rate Loans for such day and (ii) if
such Money Market Loan is denominated in any other currency, 1% plus the cost to
such Bank of funding or maintaining such Money Market Loan.  The certificate of
such Bank certifying the cost of funding or maintaining such Money Market Loan
shall be conclusive absent manifest error.

     (e)  The Agent shall determine each interest rate applicable to the Loans
hereunder.  The Agent shall give prompt notice to the Borrower and the
participating Banks by telex or facsimile transmission of each rate of interest
so determined, and its determination thereof shall be conclusive in the absence
of manifest error.

     (f)  Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section.  If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available on
a timely basis, the provisions of Section 8.01 shall apply.

     SECTION 2.08.  Fees.  (a)  The Borrower shall pay to the Agent for the
                    ----                                                   
account of the Banks ratably in proportion to their Commitments a facility fee
at a rate per annum equal to the Facility Fee Percentage on the daily average
amount of the Commitments (without regard to the outstanding principal amount of
the Loans).  Such facility fee shall accrue from and including July 23, 1997 to
but excluding the Termination Date.

     (b)  The Borrower shall pay to each of the Agent and the Arranger for its
own account fees in the amounts and at the time previously agreed upon between

Date for the quarter ending on such Quarterly Date or, if earlier, the fifth
Domestic Business Day after the date of termination of the Commitments in their
entirety.

     SECTION 2.09.  Optional Termination or Reduction of Commitments.
                    ------------------------------------------------ 

     (a)  The Borrower may, upon at least two Domestic Business Days'
irrevocable notice to the Agent, terminate at any time, or reduce from time to
time by an aggregate amount of $10,000,000 or a larger multiple of $1,000,000
the aggregate amount of the Commitments in excess of the Dollar

                                      22
<PAGE>
 
Amount of the aggregate outstanding principal amount of the Loans.

     (b)  In the absence of a Default that has occurred and is continuing and in
the event that (i) any Bank claims indemnification pursuant Section 2.16(a) or
Section 2.16(b), (ii) the Borrower is required to make an additional payment to
any Bank pursuant to Section 2.16(a), or (iii) any Bank makes a claim for
increased costs relating to taxes under Section 8.03, the Borrower shall have
the right to repay all of such Bank's outstanding Loans and to terminate such
Bank's Commitment hereunder upon ten days prior written notice to the Agent and
such Bank.  On the day on which any Bank's Commitment is terminated pursuant to
this Section 2.09(b), the Borrower shall pay all principal, accrued interest,
fees and other amounts owing to such Bank hereunder (including, without
limitation, any amounts owing under Sections 2.08, 2.13, 2.16, and 8.03).

Date shall be due and payable on the Termination Date (together with accrued
interest thereon).

     SECTION 2.11.  Optional Prepayments.  (a) The Borrower may prepay any Base
                    --------------------                                       
Rate Borrowing (or any Money Market Borrowing bearing interest at the Base Rate
pursuant to Section 8.01(a)) upon at least one Domestic Business Day's notice to
the Agent or, subject to Section 2.13, prepay any Euro-Currency Borrowing upon
at least two Euro-Currency Business Days' notice to the Agent, in any such case
in whole at any time, or from time to time in part in amounts aggregating
$10,000,000 (or the Approximate Equivalent Amount thereof) or any larger
multiple of $1,000,000 (or the Approximate Equivalent Amount thereof), by paying
the principal amount to be prepaid together with accrued interest thereon to the
date of prepayment.  Each such optional prepayment shall be applied to prepay
ratably the Loans of the several Banks included in such Borrowing.  The Borrower
may not prepay all or any portion of the principal amount of any Money Market
Loan (other than a Money Market LIBOR Loan bearing interest at the Base Rate
pursuant to Section 8.01(a)) prior to the maturity thereof.

     (b)  Upon receipt of a notice of prepayment pursuant to this Section, the
Agent shall promptly notify each Bank of the contents thereof and of such Bank's
ratable share (if any) of such prepayment and such notice shall not thereafter
be revocable by the Borrower.

     SECTION 2.12.  General Provisions as to Payments.  (a) All payments to be
                    ---------------------------------                         
made by the Borrower hereunder or under the Notes in Dollars shall be made not
later than 12:00 noon, Chicago time, on the date when due, in Federal or other
funds immediately available in Chicago, Illinois, to the Agent at its address
referred to in Section 9.01.  The Agent will promptly distribute to each Bank
its ratable share of each such payment received by the Agent for the account of
the Banks.

     (b)  Each Borrowing shall be repaid or prepaid in the currency in which it
was made in the amount borrowed and interest payable thereon shall be paid in
such currency.  All payments to be made by the Borrower hereunder or under the
Notes in any currency other than Dollars shall be made in such currency on the
date due in such funds as may then be customary for the settlement of

                                      23
<PAGE>
 
international transactions in such currency for the account of the Agent, at its
Euro-Currency Payment Office for such currency.  The Agent will promptly cause
such payments to be distributed to each Bank in like funds and currency.
Notwithstanding the foregoing provisions of this Section, if, after the making
of any Loan in any currency other than Dollars, currency control or exchange
regulations are imposed in the country which issues such currency with the
result that different types of such currency (the "New Currency") are introduced
and the type of currency in which the Borrowing was made (the "Original
Currency") no longer exists or the Borrower is not able to make payment to the
Agent for the account of the Banks in such Original Currency, then all payments
to be made by the Borrower hereunder or under the Notes in such currency shall
be made in such amount and such type of the New Currency as shall be equivalent
to the amount of such payment otherwise due hereunder or under the Notes in the
Original Currency, it being the intention of the parties hereto that the
Borrower takes all risks of the imposition of any such currency control or
exchange regulations.  In addition, notwithstanding the foregoing provisions of
this Section, if, after the making of any Borrowing in any currency other than
Dollars, the Borrower is not able to make payment to the Agent for the account
of the Banks in the type of currency in which such Borrowing was made, then such
Borrowing shall instead be repaid when due in Dollars in a principal amount
equal to the Dollar Amount (as of the date of repayment) of such Borrowing.

     (c)  Whenever any payment of principal of, or interest on, the Base Rate
Loans or of additional compensation shall be due on a day which is not a
Domestic Business Day, the date for payment thereof shall be extended to the
next succeeding Domestic Business Day.  Whenever any payment of principal of, or
interest on, the Euro-Currency Loans shall be due on a day which is not a Euro-
Currency Business Day, the date for payment thereof shall be extended to the
next succeeding Euro-Currency Business Day unless such Euro-Currency Business
Day occurs in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Currency Business Day.  Whenever any payment of
principal of, or interest on, the Money Market Loans shall be due on a day which
is not a Euro-Currency Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Currency Business Day.  If the date for any
payment of principal is extended by operation of law or otherwise, interest
thereon shall be payable for such extended time.

     (d)  Unless the Agent shall have been notified by a Bank or the Borrower
(the "Payor") prior to the date on which such Bank is to make payment to the
Agent of the proceeds of a Loan to be made by it hereunder or the Borrower is to
make a payment to the Agent for the account of one or more of the Banks, as the
case may be (each of such payments being herein called a "Required Payment"),
which notice shall be effective upon receipt, that the Payor does not intend to
make the Required Payment to the Agent, the Agent may assume that the Required
Payment has been made and may (but shall not be required to), in reliance upon
such assumption, make the amount thereof available to the intended recipient on
such date and, if the Payor has not in fact made the Required Payment to the
Agent, the recipient of such payment shall, on demand, refund to the Agent the
amount made available to it together with interest thereon in respect of the
period commencing on the date such amount was so made available by the Agent
until the date the Agent recovers such amount at a rate equal to the Federal
Funds Rate for such period, if the recipient is a Bank, and, if

                                      24
<PAGE>
 
the recipient is the Borrower, the rate which the Borrower would have been
obligated to pay hereunder for the Loans that are the subject of, or are
equivalent to, such payment for such period.

     SECTION 2.13.  Funding Losses.  The Borrower shall pay to the Agent for the
                    --------------                                              
account of each Bank, upon the request of such Bank through the Agent, such
amount or amounts as shall compensate such Bank for any reasonable loss, cost or
expense incurred by such Bank (or, subject to Section 9.07(b), by an existing or
prospective Participant in the related Loan) as a result of:

          (a)  any payment or prepayment of a Fixed Rate Loan (pursuant to
     Section 2.11 or Article VI or VIII or otherwise)  held by such Bank on a
     date other than the last day of the Interest Period applicable thereto, or
     the end of an applicable period fixed pursuant to Section 2.07(c) or

          (b)  any failure by the Borrower to borrow a Fixed Rate Loan
     (including a failure to borrow due to the occurrence of any event described
     in Section 2.04(d)) held or to be held by such Bank on the date for such
     Borrowing specified in the relevant Notice of Borrowing under Section 2.02
     or 2.03(f), such compensation to be payable in the currency specified in
     the certificate referred to below and to include, without limitation, an
     amount equal to the excess, if any, of (i) the amount of interest which
     would have accrued on the amount so paid or prepaid, or not borrowed, for
     the period from the date of such payment or prepayment or failure to borrow
     to the last day of such Interest Period (or, in the case of a failure to
     borrow, the Interest Period for such Fixed Rate Loan which would have
     commenced on the date of such failure to borrow) in each case at the
     applicable rate of interest for such Fixed Rate Loan provided for herein
     (excluding, however, the Syndicated Margin or any positive Money Market
     Margin, as the case may be, included therein) over (ii) the amount of
     interest (as reasonably determined by such Bank) which would have accrued
     to such Bank on such amount by placing such amount on deposit for a
     comparable period with leading banks in the London interbank market or in
     the New York or Chicago certificate of deposit market; provided that such
                                                            --------          
     Bank shall have delivered to the Borrower, within 60 days after the date of
     such payment or prepayment or failure to borrow, a certificate as to the
     amount and currency of such loss or expense, which certificate shall set
     forth in reasonable detail the basis for such loss or expense and shall be
     conclusive in the absence of manifest error.

     SECTION 2.14.  Computation of Interest and Fees.  Interest based on the
                    --------------------------------                        
Base Rate and interest on Borrowings denominated in pounds sterling shall be
computed on the basis of a year of 365 days (or 366 days in a leap year) and
paid for the actual number of days elapsed (including the first day but
excluding the last day).  All other interest and fees shall be computed on the
basis of a year of 360 days and paid for the actual number of days elapsed
(including the first day but excluding the last day).

     SECTION 2.15.  Judgment Currency.  If for the purposes of obtaining
                    -----------------                                   
judgment in any court it is necessary to convert a sum due from the Borrower
hereunder or under any of the Notes in the currency expressed to be payable
herein or under the Notes (the "specified currency") into another

                                      25
<PAGE>
 
currency, the parties hereto agree, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Agent could purchase the specified
currency with such other currency at the Agent's main Chicago office on the 
Euro-Currency Business Day preceding that on which final, non-appealable
judgment is given. The obligations of the Borrower in respect of any sum due to
any Bank or the Agent hereunder or under any Note shall, notwithstanding any
judgment in a currency other than the specified currency, be discharged only to
the extent that on the Euro-Currency Business Day following receipt by such Bank
or the Agent (as the case may be) of any sum adjudged to be so due in such other
currency such Bank or the Agent (as the case may be) may in accordance with
normal, reasonable banking procedures purchase the specified currency with such
other currency. If the amount of the specified currency so purchased is less
than the sum originally due to such Bank or the Agent, as the case may be, in
the specified currency, the Borrower agrees, to the fullest extent that it may
effectively do so, as a separate obligation and notwithstanding any such
judgment, to indemnify such Bank or the Agent, as the case may be, against such
loss, and if the amount of the specified currency so purchased exceeds (a) the
sum originally due to any Bank or the Agent, as the case may be, in the
specified currency and (b) any amounts shared with other Banks as a result of
allocations of such excess as a disproportionate payment to such Bank under
Section 9.11, such Bank or the Agent, as the case may be, agrees to remit such
excess to the Borrower.

     SECTION 2.16.  Taxes.  (a) All payments made by the Borrower in respect of
                    -----                                                      
principal of and interest on its Borrowings and of all other amounts payable by
it under this Agreement are payable without deduction for or on account of any
Taxes. If the Borrower shall be required by law to deduct or withhold any Taxes
from any such amount payable by it hereunder or under any of the Notes to or for
the account of any Bank, (i) such amount shall be increased as may be necessary
so that, after making such deductions or withholdings (including any deductions
or withholdings applicable to additional amounts payable pursuant to this
Section), such Bank receives an amount equal to the amount it would have
received had no such deductions or withholdings been made and (ii) the Borrower
shall make such deductions and withholdings and pay the amount thereof to the
relevant government, political subdivision or taxing authority at or prior to
the time required to be paid under applicable law (and shall promptly furnish to
the Agent, for the benefit of the Banks, official receipts evidencing such
payment). In addition, the Borrower will pay any present or future stamp or
documentary taxes or similar taxes or levies imposed by any government of any
jurisdiction outside the United States of America or any political subdivision
or taxing authority thereof from any payment by it hereunder or under any of the
Notes or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement or any of the Notes (herein called "Other Taxes").
The Borrower will indemnify each Bank and the Agent for, and hold each Bank and
the Agent harmless against, the full amount of Taxes or Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any jurisdiction on
amounts payable under this Section) paid or payable by such Bank or the Agent
and any liability of such Bank or the Agent relating thereto (including, without
limitation, penalties, interest and expenses). Notwithstanding anything set
forth above in this clause (a), the Borrower shall have no obligation to
increase the amount payable to any Bank as a result of any deduction or
withholding, or to indemnify any Bank for or hold any Bank harmless against any
Taxes or Other Taxes, to the extent that such deduction or withholding would not
have

                                      26
<PAGE>
 
been required, or such Taxes or Other Taxes would not have been paid or payable,
if such Bank's representation and warranty in clause (f) below had been accurate
or such Bank had complied with its obligations under clause (g) below.

     (b)  If the cost to any Bank of making or maintaining any Loan to the
Borrower is increased, or the amount of any sum received or receivable by any
Bank (or its Applicable Lending Office) is reduced, by an amount deemed by such
Bank to be material, which increase or reduction would not have occurred but for
the fact that the Borrower conducts business in a jurisdiction outside the
United States of America, the Borrower shall indemnify such Bank for such
increased cost or reduction within 15 days after demand by such Bank (with a
copy to the Agent).  A certificate of such Bank claiming indemnification under
this Section, setting forth the additional amount or amounts to be paid to it
hereunder and setting forth in reasonable detail a reasonable basis therefor,
shall be conclusive in the absence of manifest error.  In determining such
amount, such Bank may use any reasonable averaging and attribution methods.

     (c)  Each Bank will promptly notify the Borrower and the Agent of any event
of which it has knowledge that will entitle such Bank to any payment or
indemnification under clause (a) or (b) of this subsection and will designate a
different Domestic Lending Office, Money Market Lending Office or Euro-Currency
Lending Office, as the case may be, if such designation will avoid the need for,
or reduce the amount of, such payment or indemnification and will not, in the
sole opinion of such Bank, be otherwise materially disadvantageous to such Bank.

     (d)  If, and to the extent that, any Bank shall obtain a credit, relief or
remission for, or repayment of, any Taxes or Other Taxes indemnified or paid by
the Borrower pursuant to this Section or for any taxes for which Borrower has
made payments under Section 8.03, such Bank agrees to promptly notify the
Borrower thereof and thereupon enter into negotiations in good faith with the
Borrower to determine the basis on which an equitable reimbursement of such
taxes can be made to the Borrower.

     (e)  All tax receipts required to be delivered under this Section shall be
originals, duplicate originals or duly certified or authenticated copies within
the meaning of Treasury Regulation Section 1.905-2(a)(2).

     (f)  Each Bank represents and warrants to the Borrower and the Agent that,
as of the date of this Agreement (or, in the case of an Assignee, the date it
becomes a party hereto), it is entitled to receive payments hereunder without
any deduction or withholding for or on account of any Taxes imposed by the
United States of America or any political subdivision or taxing authority
thereof.

     (g)  Each Bank which is a Non-U.S. Person (and, if at any time the Agent
hereunder is a Non-U.S. Person, such Agent) agrees that it will, to the extent
it is able to do so under applicable law and treaties,

          (i)   within 30 days of the date of this Agreement (or, in the case of
     a Bank which

                                      27
<PAGE>
 
     becomes a party hereto pursuant to a transfer or assignment, on or prior to
     the date on which the relevant transfer or assignment becomes effective)
     deliver to the Borrower (and, in the case of a Bank, to the Agent) such
     forms (including two duly executed originals of United States Internal
     Revenue Form 1001 or 4224 or any successor to the applicable form),
     properly and accurately completed, as are necessary to claim complete or
     partial (as the case may be) exemption from withholding of United States
     federal taxes; and

          (ii)  deliver extensions or renewals of such forms on or before the
     date that any such form expires or becomes obsolete, and after the
     occurrence of any event requiring  a change in the most recent form
     previously delivered by it, 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 Agent
     or Bank from duly completing and delivering any such form with respect to
     it and such Agent or Bank so advises the Borrower (and, in the case of a
     Bank, the Agent).

For purposes of the foregoing, a Non-U.S. Person means a Person that is not (i)
a citizen or resident of the United States, (ii) a corporation or partnership
created or organized under the laws of the United States or any state thereof or
(iii) an estate or trust the income of which is subject to United States federal
income taxation regardless of its source;

     SECTION 2.17.  Maximum Interest Rate.  (a) Nothing contained in this
                    ---------------------                                
Agreement or the Notes shall require the Borrower to pay interest at a rate
exceeding the maximum rate permitted by applicable law.

     (b)  If the amount of interest payable for the account of any Bank on any
interest payment date in respect of the immediately preceding interest
computation period, computed pursuant to Section 2.07, would exceed the maximum
amount permitted by applicable law to be charged by such Bank, the amount of
interest payable for its account on such interest payment date shall be
automatically reduced to such maximum permissible amount.

     (c)  If the amount of interest payable for the account of any Bank in
respect of any interest computation period is reduced pursuant to clause (b) of
this Section and the amount of interest payable for its account in respect of
any subsequent interest computation period, computed pursuant to Section 2.07,
would be less than the maximum amount permitted by applicable law to be charged
by such Bank, then the amount of interest payable for its account in respect of
such subsequent interest computation period shall be automatically increased to
such maximum permissible amount; provided that at no time shall the aggregate
                                 --------                                    
amount by which interest paid for the account of any Bank has been increased
pursuant to this clause (c) exceed the aggregate amount by which interest paid
for its account has theretofore been reduced pursuant to clause (b) of this
Section.

     SECTION 2.18.  Extension of the Termination Date.   (a)  The Borrower may,
                    ---------------------------------                          
from time to time, by written notice to the Agent (each such notice being an
"Extension Notice") given not later

                                      28
<PAGE>
 
than 30 days but not sooner than 60 days prior to the then scheduled Termination
Date, request an extension of the Termination Date to the Euro-Currency Business
Day falling not more than 364 days after the then-scheduled Termination Date.
The Agent shall notify each Bank in writing of its receipt of an Extension
Notice within three Domestic Business Days after the Agent's receipt thereof.
Each Bank may, by a revocable written notice (a "Consent Notice") to the
Borrower and the Agent given within 30 days following the Agent's receipt of
such Extension Notice (the "Consent Deadline Date"), consent to such extension
of the Termination Date, which consent may be given or withheld by each Bank in
its absolute and sole discretion; it being understood that any Bank that fails
to respond in writing to the Borrower and the Agent by the Consent Deadline Date
shall be deemed not to have consented to such request.

     (b)  Any Bank which does not consent (or is deemed not to have consented)
to an extension of the Termination Date (a "Non-Consenting Bank") shall be
obliged during the 30 days following the Consent Deadline Date, at the request
of the Borrower and subject to the Non-Consenting Bank receiving payment in full
of all amounts owing to it under this Agreement, the Other Agreement and its
"Notes" (as defined in both this Agreement and the Other Agreement), to assign,
in accordance with the provisions of Section 9.07(c) of this Agreement and the
Other Agreement, all of its rights and obligations under this Agreement, the
Other Agreement and its "Notes" (as defined in both this Agreement and the Other
Agreement) to a Bank or other bank or financial institution nominated by the
Borrower, consented to by the Agent (such consent not to be unreasonably
withheld) and willing to participate in the Other Agreement and this Agreement
(through, in the case of this Agreement, the extended Termination Date) in the
place of such Non-Consenting Bank.

     (c)  If all Banks consent to the extension of the scheduled Termination
Date prior to the Consent Deadline Date pursuant to clause (a) above or all 
Non-Consenting Banks are replaced as parties to this Agreement prior to the
scheduled Termination Date pursuant to clause (b) above, then the Termination
Date shall be extended to the date requested by the Borrower in its Extension
Notice (effective on the previously scheduled Termination Date). In the absence
of such consents or such replacement(s), the Termination Date shall occur as
scheduled.

     substantially the form of Exhibit F hereto and covering such additional

                        REPRESENTATIONS AND WARRANTIES

     SECTION 4.01.  Representations and Warranties of the Borrower.  The
                    ----------------------------------------------      
Borrower represents and warrants to the Banks as follows:

          (a)(1) The Borrower (i) is a corporation duly incorporated, validly
     existing and in good standing under the laws of the State of Delaware and
     (ii) either is qualified to do business and in good standing in each
     jurisdiction where the ownership of its properties or the conduct of its
     business requires such qualification or is subject to no material liability
     or disability by reason of the failure to be so qualified in any such
     jurisdiction.

          (2)  The Borrower has all corporate power and authority, governmental
     permits, licenses, consents, authorizations, orders and approvals and other
     authorizations as are necessary to carry on its business substantially as
     presently conducted except for such of the foregoing the absence of which
     would not, in the aggregate, subject the Borrower to any material liability
     or disability.

          (3)  The execution, delivery and performance of the Bank Credit
     Documents, and borrowings thereunder by the Borrower, are within its
     corporate power and authority and have been duly authorized by all
     necessary corporate proceedings.

          (4)  Neither such authorization nor the execution, delivery and
     performance by the Borrower of the Bank Credit Documents, nor any borrowing
     thereunder by the Borrower when made, will conflict with, result in a
     breach of or constitute a default under any of the terms, conditions or
     provisions of any law or any regulation, order, writ, injunction or decree
     of any court or governmental authority or of the Certificate of
     Incorporation or By-Laws of the Borrower or result in the violation or
     contravention of, or the acceleration of any obligation under, or cause the
     creation of any Lien on any of the properties of the Borrower

                                      31

     pursuant to the provisions of, any indenture, agreement or other instrument
     to which it is a party or by which it is bound.

          (5)  Assuming their due execution by the Banks and the Agent, each of
     this Agreement and the Other Agreement constitutes a legal, valid and
     binding agreement of the Borrower, and the Notes (both as defined hereunder
     and under the Other Agreement), when duly executed on behalf of the
     Borrower and delivered in accordance with this Agreement and the Other
     Agreement, will constitute legal, valid and binding obligations of the
     Borrower (subject, as to enforcement of remedies, to applicable bankruptcy,
     reorganization, insolvency, moratorium or other laws affecting creditors'
     rights generally from time to time in effect and to general principles of
     equity).

          (b)  The consolidated balance sheet of the Borrower and its
     Consolidated Subsidiaries as of December 31, 1996 and the related
     consolidated statements of income and changes in financial position for the
     12 months ended that date, certified by Coopers & Lybrand, copies of all of
     which have been delivered to the Banks, fairly present the consolidated
     financial position of the Borrower and its Consolidated Subsidiaries as of
     such date and the consolidated results of their operations and changes in
     financial position for such fiscal year, in conformity with GAAP
     consistently applied.

          (c)  The unaudited consolidated balance sheet of the Borrower and its
     Consolidated Subsidiaries as of March 31, 1997 and the related unaudited
     consolidated statements of income and changes in financial position for the
     fiscal quarter then ended, a copy of which has been delivered to each of
     the Banks, fairly present, in conformity with GAAP applied on a basis
     consistent with the financial statements referred to in paragraph (b) of
     this Section, the consolidated financial position of the Borrower and its
     Consolidated Subsidiaries as of such date and their consolidated results of
     operations and changes in financial position for such fiscal quarter
     (subject to normal year-end adjustments).

          (d)  Except as disclosed in writing to the Banks prior to July 23,
     1997, there has been no material adverse change since December 31, 1996 and
     prior to July 23, 1997, in the business, operations, affairs, assets,
     condition (financial or otherwise) or results of operations of the Borrower
     and its Consolidated Subsidiaries, considered as a whole.

          (e)  Except as disclosed in writing to the Banks prior to July 23,
     1997, there is no action, suit or proceeding pending or, to the knowledge
     of the Borrower, threatened against or affecting the Borrower or any of its
     Subsidiaries in any court or before or by any arbitrator, governmental
     department, agency or instrumentality (i) which is likely to have a
     material adverse effect upon the Borrower's ability to pay and perform its
     obligations under the Bank Credit Documents in accordance with their
     respective terms or (ii) which in any manner draws into question the
     validity of any of the Bank Credit Documents.

          (f)  No Default has occurred and is continuing.

                                      32
<PAGE>
 
          (g) No consent, authorization, order or approval of (or filing or
     registration with) any governmental commission, board or other regulatory
     authority (other than routine reporting requirements) is required for the
     execution, delivery and performance by the Borrower of any of the Bank
     Credit Documents or for borrowings thereunder by the Borrower.

          (h) Each member of the ERISA Group has fulfilled its obligations under
     the minimum funding standards of ERISA and the Code with respect to each
     Plan and is in compliance in all material respects with the presently
     applicable provisions of ERISA and the Code with respect to each Plan.  No
     member of the ERISA Group has (i) sought a waiver of the minimum funding
     standard under Section 412 of the Code in respect of any Plan, (ii) failed
     to make any contribution or payment to any Plan or Multiemployer Plan or in
     respect of any Benefit Arrangement, or made any amendment to any Plan or
     Benefit Arrangement, which has resulted or could result in the imposition
     of a Lien or the posting of a bond or other security under ERISA or the
     Code or (iii) incurred any liability under Title IV of ERISA other than a
     liability to the PBGC for premiums under Section 4007 of ERISA.

          (i) The Cross-Indemnification Agreement and the Tax Sharing Agreement,
     in the respective forms, with amendments, certified to the Banks pursuant
     to Section 3.01(iv), are in full force and effect in accordance with their
     respective terms except for (1) any amendments, modifications or waivers of
     the Tax Sharing Agreement which do not materially alter the rights and
     obligations of the Borrower thereunder which as a whole place the Borrower
     in the same (or more favorable) relative financial position with respect to
     the Parent which the Borrower would have been in if the Borrower were not
     consolidated with the Parent for purposes of filing federal, state or local
     or other income tax returns, (2) any amendments to the Cross-
     Indemnification Agreement for the purpose of placing the Borrower and the
     Parent in the same financial positions with respect to each other which
     they would have been in if the Borrower and the Parent were not members of
     the same ERISA Group, including the allocation of, and indemnification with
     respect to, assets and funded and unfunded liabilities among the Borrower,
     the Parent, Affiliates, Subsidiaries and their respective Plans in such
     manner as is fair and equitable to the Borrower and its Subsidiaries, (3)
     any amendments, modifications or waivers of the Cross-Indemnification
     Agreement or the Tax Sharing Agreement which do not, in the aggregate,
     materially reduce the rights of the Borrower thereunder against the Parent
     or materially increase the obligations of the Borrower thereunder to the
     Parent and (4) any other amendments, modifications or waivers of such
     instruments to which the Required Banks have consented.  True and complete
     copies of all such amendments, modifications and waivers have been
     delivered to the Agent for each of the Banks.  No amount that may be due
     under the Cross-Indemnification Agreement or the Tax Sharing Agreement from
     the Parent to the Borrower or to the Parent from the Borrower is
     delinquent, except such amount as the Borrower or the Parent may be
     contesting in good faith.

          (j) Each corporate Subsidiary is a corporation duly incorporated,
     validly existing and in good standing under the laws of its jurisdiction of
     incorporation, and has all corporate

                                      33
<PAGE>
 
     powers and all governmental licenses, authorizations, consents and
     approvals required to carry on its business as now conducted except for
     licenses, authorizations, consents or approvals the absence of which will
     not materially and adversely affect the business of the Borrower and its
     Consolidated Subsidiaries taken as a whole.

          (k) The Borrower is not an "investment company" within the meaning of
     the Investment Company Act of 1940, as amended.

          (l) There are no Liens on any asset of the Borrower or any Subsidiary
     on July 23, 1997 which would have been prohibited if Section 5.02 of this
     Agreement had been in effect on the date the Borrower or such Subsidiary,
     as the case may be, acquired such asset.

          (m) Except as disclosed in writing to the Banks, the description of
     environmental matters affecting the Borrower and its Subsidiaries contained
     in each of the Borrower's reports delivered to the Banks pursuant to clause
     (ii) of Section 5.01(c) complied in all material respects as of the date of
     such report with the requirements of the Securities Exchange Act of 1934,
     as amended, and the rules and regulations promulgated thereunder.

     with this Agreement or the business, operations, affairs, assets, condition
     (financial or otherwise) or results of operations of the Borrower and its

     SECTION 5.02.  Limitation on Liens.  Neither the Borrower nor any
                    -------------------                               
Subsidiary will issue, assume or guarantee any Debt secured by any Lien upon any
asset of the Borrower or any Subsidiary or grant any Lien on any such asset to
secure any such Debt without effectively providing that all of the Notes
(together with, if the Borrower so determines, any other Debt then existing and
any other Debt thereafter created ranking equally with the Notes) shall be
secured equally and ratably with (or prior to) such Debt so long as such Debt
shall be so secured.  To the extent the following Liens would otherwise be
prohibited by the foregoing provisions, the foregoing provisions shall not apply
to:

          (a) Liens on any asset of a corporation existing at the time it
     becomes a Subsidiary of the Borrower or at the time it is merged into or

     construction or improvements thereon or Debt incurred to provide funds for
     any such purpose in a principal amount not exceeding the cost of such
     construction or improvements;

     or another Subsidiary;

          (e) Liens in favor of the United States of America or any state
     thereof or any department, agency, instrumentality or political subdivision
     of any such jurisdiction to secure partial, progress, advance or other
     payments pursuant to any contract or statute or to secure

                                      36

     secure Debt in respect of any pollution control, industrial revenue bond or
     other similar type of financing;

          (f) Liens required by any contract or statute in order to permit the
     Borrower or a Subsidiary to perform any contract or subcontract made by it

          (g) mechanics', suppliers', materialmen's and similar Liens arising in

     adequate reserves are being maintained;

          (h) Liens securing obligations of the Borrower or any Subsidiary to
     pay the deferred purchase price of services not exceeding in the aggregate
     $10,000,000;

          (i) the Lien of any judgment or attachment in respect of any Debt, so
     long as (1) the Borrower in good faith by appropriate action, promptly
     initiated and diligently conducted, shall contest or cause to be contested
     the validity, amount, extent or application thereof and (2) such action
     shall operate to prevent the sale or foreclosure (or the posting of notices
     preparatory to any sale or foreclosure) of any part of any asset to satisfy
     such Lien prior to a final determination of such action;

          (j) Liens for taxes not delinquent or being contested in good faith
     based on the advice of counsel that such contest is meritorious and by
     appropriate proceedings and for which reserves adequate under GAAP are
     being maintained; and

          (k) any extension, renewal or replacement (or successive extensions,
     renewals or replacements), in whole or in part, of any Lien referred to in
     the foregoing clauses (a) to (h) inclusive or of any Debt secured thereby,
     provided that the principal amount of Debt secured thereby shall not exceed
     --------
     the principal amount of Debt so secured at the time of such extension,
     renewal or replacement, and that such extension, renewal or replacement
     Lien shall be limited to all or part of substantially the same property
     which secured the Lien extended, renewed or replaced (plus improvements on
     such property);

provided that the Borrower and any one or more Subsidiaries may issue, assume or
- --------                                                                        
guarantee Debt secured by Liens which would otherwise be subject to the
foregoing restrictions or grant any such Lien to secure any such Debt in an
aggregate principal amount which, together with the aggregate outstanding
principal amount of all Debt of the Borrower and the Subsidiaries which would
otherwise be subject to the foregoing restrictions (not including Debt permitted
to be secured under clauses (a) to (g) inclusive above) and the aggregate Value
of the Sale and Lease-Back Transactions

                                      37
<PAGE>
 
(as such terms are defined in Section 5.03 hereof) in existence at such time
(not including Sale and Lease-Back Transactions as to which the Borrower has
complied with Section 5.03(b) hereof) does not at any one time exceed 15% of the
consolidated total assets of the Borrower and its Consolidated Subsidiaries.

     SECTION 5.03.  Limitation on Sale and Lease-Back.  Neither the Borrower nor
                    ---------------------------------                           
any Subsidiary will enter into any arrangement with any Person (other than the
Borrower or a Subsidiary), or to which any such Person is a party, providing for
the leasing to the Borrower or a Subsidiary for a period of more than three
years of any property which

has been or is to be sold or transferred by the Borrower or such Subsidiary to
such Person or to any Person (other than the Borrower or a Subsidiary), to which
funds have been or are to be advanced by such Person on the security of the
leased property (in this Section and in Section 5.02 hereof called a "Sale and
Lease-Back Transaction") unless either:

          (a) the Borrower or such Subsidiary would be entitled, pursuant to the
     provisions of Section 5.02 hereof, to incur Debt in a principal amount
     equal to or exceeding the Value of such Sale and Lease-Back Transaction,
     secured by a Lien on the property to be leased, without equally and ratably
     securing the Notes; or

          (b) the Borrower (and in any such case the Borrower covenants and
     agrees that it will do so) during or immediately after the expiration of
     four months after the effective date of such Sale and Lease-Back
     Transaction (whether made by the Borrower or a Subsidiary) applies to the
     voluntary retirement of Debt of the Borrower ranking at least pari passu
     with the Notes an amount equal to the Value of such Sale and Lease-Back
     Transaction, less the principal amount of such Debt of the Borrower
     voluntarily retired by the Borrower within such four-month period,
     excluding retirements of such Debt as a result of conversions or pursuant
     to mandatory sinking fund or repayment provisions or (other than in the
     case of commercial paper) by payment at maturity.

For purposes of Section 5.02 hereof and this Section, the term "Value" shall
mean, with respect to a Sale and Lease-Back Transaction, as of any particular
time, the amount equal to the greater of (i) the net proceeds of the sale or
transfer of the property leased pursuant to such Sale and Lease-Back Transaction
or (ii) the fair value in the opinion of the Board of Directors of the Borrower
of such property at the time of entering into such Sale and Lease-Back
Transaction, in either case divided first by the number of full years of the
term of the lease and then multiplied by the number of full years of such term
remaining at the time of determination, without regard to any renewal or
extension options contained in the lease.

     SECTION 5.04.  Consolidation, Merger, Disposition of Assets.  The Borrower
                    --------------------------------------------               
will not (i) consolidate or merge with or into any other Person or (ii) sell,
lease or otherwise transfer all or any substantial part of its assets (whether
in a single transaction or in a series of related transactions) to any other
Person; provided that the Borrower may merge with another Person if (A) the
        --------                                                           
Borrower is the corporation surviving such merger and (B) immediately after
giving effect to such merger, no

                                      38
<PAGE>
 
Default shall have occurred and be continuing; and provided further that the
                                                   -------- -------         
Borrower may consolidate or merge with or into the Parent if (A) the Parent
theretofore expressly assumes the obligations of the Borrower hereunder and
under the Notes by an instrument satisfactory in form and substance to the
Required Banks and (B) immediately after giving effect to such consolidation or
merger and such assumption, no Default shall have occurred and be continuing;
and provided further that the Borrower may (A) sell its inventory in the
    -------- -------                                                    
ordinary course of business and (B) sell, lease or otherwise transfer such of
its assets (including all or any portion of the stock of any Subsidiary) on an
arms-length basis to an Internally-Funded Subsidiary.  The Borrower will not
permit any Subsidiary which constitutes a substantial part of its assets to
consolidate or merge with or into, or transfer all or substantially all of its
assets (whether in a single transaction or in a series of related transactions)
to, any Person other than the Borrower or a Wholly-Owned Consolidated
Subsidiary. For purposes of this Section, "substantial part of its assets" means
assets (including Subsidiaries or other Persons and valued at the higher of book
or fair market value) (y) representing more than 25% of the consolidated assets
of the Borrower and its Subsidiaries as reflected in the then most recent
consolidated annual financial statements of the Borrower and its Subsidiaries
delivered pursuant to Section 5.01(a) or (z) responsible for more than 25% of
the consolidated net revenues or of the consolidated net income of the Borrower
and its Subsidiaries as reflected in the financial statements referred to in the
preceding clause (y).  Notwithstanding the foregoing, the Banks will not
unreasonably withhold their consent to any sale, lease or other transfer of
assets by the Borrower or any of its Subsidiaries.

     SECTION 5.05.  Minimum Consolidated Net Worth.  Consolidated Net Worth will
                    ------------------------------                              
at no time be less than $1,500,000,000.

     SECTION 5.06.  Transactions with Affiliates.  The Borrower will not, and
                    ----------------------------                             
will not permit any Subsidiary to, directly or indirectly, pay any funds to or
for the account of, make any investment (whether by acquisition of stock or
indebtedness, by loan, advance, transfer of property, Guarantee or other
agreement to pay, purchase or service, directly or indirectly, any Debt, or
otherwise) in, lease, sell, transfer or otherwise dispose of any assets,
tangible or intangible, to, or participate in, or effect any transaction in
connection with any joint enterprise or other joint arrangement with, any
Affiliate; provided, however, that the foregoing provisions of this Section
           --------  -------                                               
shall not prohibit (a) the Borrower from declaring or paying any lawful dividend
to, or repurchasing its common stock from, any Affiliate so long as, after
giving effect thereto, no Default shall have occurred and be continuing, (b) the
Borrower or any Subsidiary (1) from making sales to or purchases from or leasing
from any Affiliate and, in connection therewith, extending credit or making
payments, or (2) from making payments for services rendered by any Affiliate or
(3) from participating in, or effecting any transaction in connection with, any
joint enterprise or other joint arrangement with any Affiliate if such sales,
purchases or leases are made or such services are rendered or the Borrower or
such Subsidiary participates in the ordinary course of business of the Borrower
or such Subsidiary, as the case may be, and, in the aggregate during each fiscal
year of the Borrower, the terms and conditions of all such sales, purchases,
leases, rendered services and participations are not materially less favorable
to the similar transactions with Persons who are not Affiliates and (c) the
Borrower or any Subsidiary from making payments of principal, interest and
premium on any Debt of the Borrower

                                      39
<PAGE>
 
or such Subsidiary held by an Affiliate if the terms of such Debt are
substantially as favorable to the Borrower or such Subsidiary as the terms which
could have been obtained at the time of the creation of such Debt from a lender
which was not an Affiliate.

     SECTION 5.07.  Use of Proceeds.  The proceeds of the Loans made under this
                    ---------------                                            
Agreement will be used for general corporate purposes.  None of such proceeds
will be used, directly or indirectly, for the purpose, whether immediate,
incidental or ultimate, of purchasing or carrying any "margin stock" within the
meaning of Regulation U.

     Subsidiary;

     seeking liquidation, reorganization or other relief with respect to itself
     or its debts under any bankruptcy, insolvency or other similar law now or

     shall be commenced against the Borrower, any Material Subsidiary or any two
     or more Subsidiaries which, if combined, would constitute a Material
     Subsidiary, seeking liquidation, reorganization or other relief with
     respect to it or its debts under any bankruptcy, insolvency or other

     constitute a Material Subsidiary, under the federal bankruptcy laws as now
     or hereafter in effect;

          (h) Termination of Plan:  any member of the ERISA Group shall fail to
              -------------------                                              
     pay when due an amount or amounts aggregating in excess of $20,000,000

                    -----------------------------                        
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under this Agreement and the Notes as are delegated to

                    --------------------                                     
shall have the same rights and powers under this Agreement and its Notes as any
other Bank and may exercise or refrain from exercising the same as though it
were not the Agent, and The First National Bank of Chicago and its Affiliates
may accept deposits from, lend money to, and generally engage in any kind of
business with the Borrower or any Subsidiary or any Affiliate as if it were not
the Agent hereunder.

     SECTION 7.03.  Action by Agent.  The obligations of the Agent hereunder are
                    ---------------                                             
only those expressly set forth herein.  Without limiting the generality of the
foregoing, the Agent shall not be required to take any action with respect to
any Default, except as expressly provided in Article VI.

     SECTION 7.04.  Employment and Reliance on Agents and Counsel.  The Agent
                    ---------------------------------------------            
may execute any of its duties as Agent hereunder by or through employees,
agents, and attorneys-in-fact and shall not be answerable to the Banks, except
as to money or securities received by it or its authorized agents, for the
default or misconduct of any such agents or attorneys-in-fact selected by it
with reasonable care.  In addition, the Agent may consult with legal counsel
(who may be employees of the Agent or counsel for the Borrower), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

     SECTION 7.05.  Liability of Agent.  Neither the Agent, the Arranger, nor
                    ------------------                                       
any of their respective directors, officers, agents or employees shall be liable
for any action taken or not taken by it in connection herewith (i) with the
consent or at the request of the Required Banks or (ii) in the absence of its
own gross negligence or willful misconduct.  Neither the Agent, the Arranger,
nor any of their respective directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into or verify (i) any
statement, warranty or representation made in connection with this Agreement or
any Borrowing hereunder; (ii) the performance or observance of any of the
covenants or agreements of the Borrower; (iii) the satisfaction of any condition
specified in Article III, except receipt of items required to be delivered to
the Agent; or (iv) the validity, effectiveness or genuineness of this Agreement,
the Notes or any other instrument or writing furnished in connection herewith.
Neither the Agent nor the Arranger shall incur any liability by acting in
reliance upon any Note, notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex, facsimile transmission or similar
writing) believed by it in good faith to be genuine or to be signed by the
proper party or parties.

     SECTION 7.06.  Reimbursement and Indemnification.  The Banks agree to
                    ---------------------------------                     
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (i) for any amounts not reimbursed by the Borrower for which the
Agent (for clarity, in its capacity as Agent, not as a Bank) is entitled to
reimbursement by the Borrower under this Agreement, (ii) for any other expenses
incurred by the Agent on behalf of the Banks, in connection with the
administration and enforcement of this Agreement and the Notes and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,

<PAGE>
 
of this Agreement, the Notes or any other document delivered in connection
herewith or the transactions contemplated hereby, or the enforcement of any of

negligence or willful misconduct of the Agent.

     SECTION 7.07.  Credit Decision.  Each Bank acknowledges that it has,
                    ---------------                                      
independently and without reliance upon the Agent, the Arranger or any other
Bank, and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon the Agent,
the Arranger or any other Bank, and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking any action under this Agreement.

     SECTION 7.08.  Successor Agent.  The Agent may resign at any time by giving
                    ---------------                                             
written notice thereto to the Banks and the Borrower.  Upon any such
resignation, the Required Banks shall have the right to appoint a successor
Agent who has been approved by the Borrower (such approval not to be
unreasonably withheld or delayed).  If no successor Agent shall have been so
appointed by the Required Banks, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving notice of resignation, then the
retiring Agent may, on behalf of the Banks, appoint a successor Agent.  The
successor Agent shall be (i) a commercial bank organized under the laws of the
United States of America or of any state thereof and having a combined capital
and surplus of at least $100,000,000 and (ii) a Bank, unless the Borrower
consents to the successor Agent not being a Bank, which consent may not be
unreasonably withheld or delayed.  Upon the acceptance by a successor Agent of
its appointment as Agent hereunder, it shall thereupon succeed to and become
vested with all the rights and duties of the retiring Agent and the retiring
Agent shall be discharged from its duties and obligations hereunder.  Each
successor Agent shall notify promptly the Borrower of its appointment as Agent
hereunder.  After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent.

     SECTION 7.09.  Co-Agents.  None of the Banks identified on the signature
                    ---------                                                
pages of this Agreement as a "Co-Agent" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement other than those
applicable to all Banks as such.  Without limiting the foregoing, none of the
Banks so identified as a "Co-Agent" shall have or be deemed to have any
fiduciary relationship with any Bank.  Each Bank acknowledges that it has not
relied, and will not rely, on any of the Banks identified as Co-Agents in
deciding to enter into this Agreement or in taking or not taking action
hereunder.

     SECTION 8.01.  Basis for Determining Interest Rate Inadequate or Unfair.
                    --------------------------------------------------------  
(a) If on or prior to the first day of any Interest Period for any Fixed Rate
Borrowing (other than a Money Market Rate Loan):

          (1)  the Agent is advised by the Reference Banks that deposits in the
     applicable currency (in the applicable amounts) are not being offered to
     the Reference Banks in the relevant market for such Interest Period, or

          (2)  the Required Banks advise the Agent that the London Interbank
     Offered Rate as determined by the Agent will not adequately and fairly
     reflect the cost to such Banks of funding their Euro-Currency Loans or
     Money Market LIBOR Loans, as the case may be, for such Interest Period,

the Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon until the Agent notifies the Borrower that the circumstances giving
rise to such notice no longer exist: (A) the New York Interbank Offered Rate
shall replace the London Interbank Offered Rate for purposes of interest rate
determinations hereunder for Euro-Currency Borrowings and Money Market LIBOR
Borrowings for such Interest Period (and all references herein to the London
interbank market and the London Interbank Offered Rate for such purposes shall,
unless the context otherwise requires, be deemed to be references to the New
York interbank market and the New York Interbank Offered Rate, respectively), as
the case may be, and (B) unless the Borrower notifies the Agent at least one
Domestic Business Day before the date of any Fixed Rate Borrowing for which a
Notice of Borrowing has previously been given that it elects not to borrow on
such date or that it elects to borrow in another currency such that clause (1)
or (2) above is not applicable thereto,

          (i)  if such Fixed Rate Borrowing is a Euro-Currency Borrowing, the
     interest rate for such Euro-Currency Borrowing shall be determined on the
     basis of the New York Interbank Offered Rate if all of the procedures set
     forth herein for a Euro-Currency Borrowing on such basis (including the
     required notice to the Banks) can be complied with at such time or, if
     clause (1) or (2) of this subsection is applicable to the New York
     Interbank Offered Rate at such time, such Euro-Currency Borrowing shall
     instead be made as a Base Rate Borrowing; provided that, if such Euro-
                                               --------                   
     Currency Borrowing was to be denominated in a currency other than Dollars,
     the principal amount of the Base Rate Borrowing shall be the Dollar Amount
     of the principal amount of such Euro-Currency Borrowing, and

          (ii) if such Fixed Rate Borrowing is a Money Market LIBOR Borrowing,
     the interest rate for such Money Market LIBOR Borrowing shall be determined
     on the basis of the New York Interbank Offered Rate if all of the
     procedures set forth herein for a Money Market LIBOR Borrowing on such
     basis (including the required notice to the Banks) can be complied with at
     such time or, if clause (1) or (2) of this subsection is applicable to the
     New York Interbank Offered Rate at such time, the Money Market LIBOR Loans
     comprising such Borrowing shall be made in Dollars in a principal amount
     equal to the Dollar Amount of the principal amount of such Money Market
     LIBOR Borrowing and shall bear interest for each

                                      45
<PAGE>
 
     day from and including the first day to but excluding the last day of the
     Interest Period applicable thereto at the Base Rate for such day.

     (b) If clause (1) or (2) of subsection (a) of this Section becomes
applicable when the New York Interbank Offered Rate has replaced the London
Interbank Offered Rate hereunder, then the Agent shall give notice to the
Borrower of such condition and the Borrower and the Agent (in consultation with
the Banks) shall promptly enter into negotiations in good faith with a view to
agreeing upon an alternative basis (a "Substitute Basis") acceptable to the
Borrower and the Banks for determining the interest rate which shall be
applicable to the affected Euro-Currency Borrowings or Money Market LIBOR
Borrowings, which rate shall reflect the cost to the Banks of maintaining such
Euro-Currency Borrowings plus the applicable Syndicated Margin or maintaining
such Money Market LIBOR Loans plus any applicable Money Market Margin, as the
case may be.  If, prior to the expiration of 20 days from the date of such
notice by the Agent, the Borrower and the Banks shall agree upon a Substitute
Basis, interest on such Euro-Currency Borrowings or Money Market LIBOR
Borrowings for the affected Interest Periods commencing during the period
beginning two Euro-Currency Business Days after the date of such notice and
ending on the date three Euro-Currency Business Days after the Agent notifies
the Borrower and the Banks that the condition specified in clause (1) or (2) of
subsection (a) of this Section has ceased to be in effect shall be determined on
such Substitute Basis.  If no such agreement has been reached by the expiration
of such 20-day period, the Agent shall so notify the Banks and each Bank shall,
within ten days after the date of such notice, notify the Borrower (through the
Agent) of the rate (or the basis of determining the rate) at which it is
prepared to maintain such Euro-Currency Borrowings or Money Market LIBOR
Borrowings held by it hereunder for the affected Interest Periods (which rate
shall reflect the cost to such Bank of maintaining such Borrowings plus the
applicable Syndicated Margin or plus any applicable positive Money Market
Margin, as the case may be) and such rate (or basis) shall be applicable to such
Euro-Currency Borrowings or Money Market LIBOR Borrowings, as the case may be,
held by it for the affected Interest Periods applicable thereto referred to in
the preceding sentence.  The Agent shall determine the total amount of interest
payable by the Borrower on each date for the payment of interest hereunder
determined in accordance with this subsection (b) (to the extent it has received
the necessary information from the Banks) and notify the Borrower of such total
amount (provided that no Bank's right to receive any interest payable to it
hereunder shall be impaired by its failure to provide such information to the
Agent).  The Borrower shall have the right at any time to suspend the obligation
of each Bank notifying a rate (or basis) pursuant to the second preceding
sentence of this subsection to make Euro-Currency Loans.

     SECTION 8.02.  Illegality.  If, after July 23, 1997, the adoption of any
                    ----------                                               
applicable law, rule or regulation, or any change therein, or any change 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 Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for any Bank (or its Applicable Lending Office) to make, maintain or
fund its Euro-Currency Loans and such Bank shall so notify the Agent, the Agent
shall forthwith give notice thereof to the other Banks and the Borrower,
whereupon until

                                      46
<PAGE>
 
such Bank notifies the Borrower and the Agent that the circumstances giving rise
to such suspension no longer exist, the obligation of such Bank to make Euro-
Currency Loans shall be suspended. Before giving any notice to the Agent
pursuant to this Section, such Bank shall designate a different Applicable
Lending Office if such designation will avoid the need for giving such notice
and will not, in the judgment of such Bank, be otherwise materially
disadvantageous to such Bank.  If such Bank shall determine that it may not
lawfully continue to maintain and fund any of its outstanding Euro-Currency
Loans to maturity and shall so specify in such notice, the Borrower shall
immediately prepay in full the then outstanding principal amount of each such
affected Euro-Currency Loan, together with accrued interest thereon.
Concurrently with prepaying each such affected Euro-Currency Loan, the Borrower
shall borrow a Base Rate Loan (or, subject to Section 2.03 and the willingness
of such Bank in its own discretion to submit a Money Market Quote, a Money
Market Rate Loan) from such Bank in a principal amount equal to the Dollar
Amount of the principal amount of such affected Euro-Currency Loan for an
Interest Period coincident with the remaining term of the Interest Period
applicable to such affected Euro-Currency Loan, and such Bank shall make such a
Base Rate Loan.

     SECTION 8.03.  Increased Cost and Reduced Return.  (a) If on or after (x)
                    ---------------------------------                         
July 23, 1997, in the case of any Syndicated Loan or any obligation to make
Syndicated Loans or (y) the date of the related Money Market Quote, in the case
of any Money Market Loan, the adoption of any applicable law, rule or
regulation, or any change therein, or any change 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 Bank (or its Applicable Lending Office) with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency:

          (i)  shall subject any Bank (or its Applicable Lending Office) to any
     tax, duty or other charge with respect to its Fixed Rate Loans, its Notes
     or its obligation to make Euro-Currency Loans, or shall change the basis of
     taxation of payments to any Bank (or its Applicable Lending Office) of the
     principal of or interest on its Fixed Rate Loans or any other amounts due
     under this Agreement in respect of its Fixed Rate Loans or its obligation
     to make Euro-Currency Loans (except for changes in the rate of tax on the
     overall net income of such Bank or its Applicable Lending Office imposed by
     the jurisdiction in which such Bank's principal executive office or
     Applicable Lending Office is located) or

          (ii) shall impose, modify or deem applicable any reserve, special
     deposit, deposit insurance assessment or similar requirement (including,
     without limitation, any such requirement imposed by the Board of Governors
     of the Federal Reserve System, but excluding with respect to any Euro-
     Currency Loan or Money Market LIBOR Loan any such requirement included in
     an applicable Euro-Currency Reserve Percentage) against assets of, deposits
     with or for the account of, or credit extended by, any Bank (or its
     Applicable Lending Office) or shall impose on any Bank (or its Applicable
     Lending Office) or on the London interbank market any other condition
     affecting its Fixed Rate Loans, its Notes or its obligation to make Euro-
     Currency Loans,

                                      47
<PAGE>
 
and the result of any of the foregoing is to increase the cost to such Bank (or
its Applicable Lending Office) of making or maintaining any Fixed Rate Loan, or
to reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under its Notes with respect
thereto, by an amount deemed by such Bank to be material, then, within 15 days
after demand by such Bank (with a copy to the Agent), the Borrower shall pay to
such Bank (without duplication of amounts otherwise payable hereunder) such
additional amount or amounts as will compensate such Bank for such increased
cost or reduction with respect to such affected Fixed Rate Loan or such affected
sum.

     (b) If any Bank shall have reasonably determined that, after July 23, 1997,
the adoption of any applicable law, rule or regulation regarding capital
adequacy or any change therein, or any change 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 Bank (or its Applicable Lending Office) with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or has had the effect of
reducing the rate of return on the capital of such Bank (or its parent) as a
consequence of its obligations hereunder to a level below that which such Bank
(or its parent) could have achieved but for such adoption, change or compliance
(taking into consideration such Bank's policies with respect to capital
adequacy) by an amount deemed by such Bank to be material, then from time to
time, within 15 days after demand by such Bank (with a copy to the Agent), the
Borrower shall pay to such Bank (without duplication of amounts otherwise
payable hereunder) such additional amount or amounts as will compensate such
Bank (or its parent) for such reduction.

     (c) Each Bank will promptly notify the Borrower and the Agent of any event
of which it has knowledge, occurring after July 23, 1997, which will entitle
such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise materially disadvantageous to such Bank.  A certificate of
any Bank claiming compensation under this Section, setting forth the additional
amount or amounts to be paid to it hereunder and setting forth in reasonable
detail a reasonable basis therefor, shall be conclusive in the absence of
manifest error.  In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

     (d) Notwithstanding any other provision of this Agreement, the Borrower
shall have no obligation to make any payment under this Section 8.03 to the
extent that such payment would not have been required (i) if such Bank's
representation and warranty in Section 2.16(f) had been accurate, or (ii) if
such Bank had complied with its obligations under Section 2.16(g).

     SECTION 8.04.  Substitute Loans.  If (i) the obligation of any Bank to make
                    ----------------                                            
Euro-Currency Loans has been suspended pursuant to Section 8.01(b) or 8.02 or
(ii) any Bank has demanded compensation under Section 8.03(a) and the Borrower
shall, by at least five Euro-Currency Business Days' prior notice to such Bank
through the Agent, have elected that the provisions of this Section shall apply
to such Bank, then, unless and until such Bank notifies the Borrower that the
circumstances giving rise to such suspension or demand for compensation no
longer apply:

                                      48
<PAGE>
 
          (a) all Loans denominated in Dollars which would otherwise be made by
     such Bank as Euro-Currency Loans shall be made instead as Base Rate Loans,

          (b) all Loans denominated in a currency other than Dollars which would
     otherwise be made by such Bank as Euro-Currency Loans shall be made instead
     as Base Rate Loans in Dollars in a principal amount equal to the Dollar
     Amount of the principal amount of such Euro-Currency Loans, and

          (c) after each of its Euro-Currency Loans has been repaid, all
     payments of principal which would otherwise be applied to repay such Fixed
     Rate Loans shall instead be applied to repay its Loans made pursuant to
     Section 8.02 or clauses (a) or (b) above.

     SECTION 8.05.  Certain Reserve Compensation.  Each Bank may require the
                    ----------------------------                            
Borrower to pay, contemporaneously with each payment of interest on the Euro-
Currency Borrowings of the Borrower, additional interest on the related Euro-
Currency Loan of such Bank at a rate per annum equal to the excess of (i)(A) the
applicable London Interbank Offered Rate divided by (B) one minus the Euro-
Currency Reserve Percentage over (ii) the rate specified in clause (i)(A).  In
addition, each Bank may require the Borrower to pay, contemporaneously with each
payment of interest on the Euro-Currency Borrowings of the Borrower which are
denominated in pounds sterling, additional interest on the related Euro-Currency
Loan of such Bank at the percentage calculated from time to time by such Bank to
be the percentage required to fully compensate such Bank for all reserve costs,
liabilities, expenses and assessments which have been incurred by such Bank (or
its Applicable Lending Office) in complying with any and all requirements of any
relevant United Kingdom banking authority or authorities applicable to such Bank
(or its Applicable Lending Office) regarding the making, funding or maintaining
of such Euro-Currency Loan  (including, without limitation, any and all liquid
asset maintenance requirements of the Bank of England).  A certificate of any
Bank claiming compensation under the preceding sentence, setting forth the
additional interest to be paid to it thereunder and setting forth in reasonable
detail a reasonable basis therefor, shall be conclusive in the absence of
manifest error, and in determining the amount of such interest, such Bank may
use any reasonable averaging and attribution methods.

     Any Bank wishing to require payment of such additional interest (x) shall
so notify the Borrower and the Agent, in which case such additional interest on
the Euro-Currency Loans of such Bank shall be payable in the currency of such
Loan to such Bank at the place indicated in such notice with respect to each
Interest Period commencing at least five Euro-Currency Business Days after the
giving of such notice and (y) shall notify the Borrower at least five Euro-
Currency Business Days prior to each date on which interest is payable on such
Euro-Currency Loans of the amount (and currency thereof) then due it under this
Section.

     SECTION 8.06.  Substitution of Bank.  If (i) the obligation of any Bank to
                    --------------------                                       
make Euro-Currency Loans has been suspended pursuant to either Section 8.01(b)
or Section 8.02 of either this Agreement or the Other Agreement or (ii) any Bank
has demanded compensation under any of Sections 2.16, 8.03 or 8.05 of either
this Agreement or the Other Agreement, the Borrower shall have the right, with
the assistance of the Agent, to seek a mutually satisfactory substitute bank or
banks (which may be one or more of the Banks) to purchase and assume all of the
rights and obligations of such Bank under this Agreement, the Other Agreement
and such Bank's "Notes" (as defined in both this Agreement and the Other
Agreement), all in accordance with the provisions of Section

                                      49

9.07(c) of this Agreement and Section 9.07(c) of the Other Agreement and subject
to such Bank receiving payment in full of all amounts owing to it under this
Agreement, the Other Agreement, and its "Notes" (as defined in both this
Agreement and the Other Agreement).

     The Borrower hereby agrees to indemnify the Agent, the Arranger and each
Bank (and  their respective directors, officers and employees) from and hold
each of them harmless against any and all losses, claims, damages, penalties,
judgments, liabilities and expenses (including, without limitation, all expenses

     SECTION 9.07.  Successors and Assigns.  (a)  The provisions of this
                    ----------------------                              
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks and the Agent.

     (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans.  In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement.  Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrower hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
                                                                      --------

any modification, amendment or waiver of this Agreement described in clause (ii)

agrees that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Sections 2.13, 2.15, 2.16, 9.04 and
Article VIII to the extent of its participating interest and with such benefits
to be determined as if the related Bank had not granted such participation.  An
assignment or other transfer which is not permitted by subsection (c) or (d)
below shall be given effect for purposes of this Agreement only to the extent of
a participating interest granted in accordance with this subsection (b).

     (c) With (and subject to) the written consent of the Borrower and the Agent
(such consents not to be unreasonably withheld and, in the case of an assignment
to an Affiliate, not to be required), any Bank may at any time assign to one or
more banks or other institutions (each an "Assignee") all, or a proportionate
part of all, of its rights and obligations under this Agreement and the Notes,
and such Assignee shall assume such rights and obligations, pursuant to an
Assignment and Assumption Agreement in substantially the form of Exhibit G
hereto executed by such Assignee and such transferor Bank; provided, that
simultaneously with each such assignment, the transferor Bank shall assign to
the same Assignee the same proportionate share of all of its rights and
obligations, if any, under the Other Agreement in accordance with the provisions
of Section 9.07(c) of the Other Agreement.  Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required.  Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Agent and the Borrower
shall make appropriate arrangements so that, if required, new Notes are issued
to the Assignee.  In connection with any such assignment under this Agreement,
the transferor Bank shall pay to the Agent an administrative fee for processing
such assignment equal to $1,500.

                                      52
<PAGE>
 
     (d) Any Bank may at any time assign all or any portion of its rights under
this Agreement and its Notes to a Federal Reserve Bank (without any requirement
to obtain the consent of the Borrower or the Agent thereto).  No such assignment
shall release the transferor Bank from its obligations hereunder.

     (e) No Assignee, Participant or other transferee of any Bank's rights shall
be entitled to receive any greater payment under Section 8.03 or 8.05 than such
Bank would have been entitled to receive with respect to the rights transferred,
unless such transfer is (i) made with the Borrower's prior written consent or
(ii) made to either (y) a Bank already party to this Agreement at the time of
such assignment or (z) an affiliate of the transferor Bank.

     (f) If any Reference Bank assigns all of its rights and obligations under
this Agreement and its Notes to an unaffiliated institution, the Agent shall, in
consultation with the Borrower and with the consent of the Required Banks,
appoint another Bank to act as a Reference Bank hereunder.

     SECTION 9.08.  Survival.  The obligations of the Borrower under Article
                    --------                                                
VIII and Sections 2.16 and 9.04 shall survive the repayment of the Loans and the
termination of the Commitments.

     SECTION 9.09.  Acknowledgement.  The Borrower acknowledges that the Banks
                    ---------------                                           
have entered into this Agreement in reliance on the Borrower's assurance that it
does not intend to use the proceeds of any Borrowings hereunder in a manner
which would violate any applicable law or governmental rule or regulation.


     SECTION 9.10.  Headings.  The Table of Contents and Article and Section
                    --------                                                
headings used herein shall not affect the interpretation of any provision of
this Agreement.

     SECTION 9.11.  Sharing of Setoffs.  Each Bank agrees that, if it shall, by
                    ------------------                                         
exercising any right of setoff or counterclaim or otherwise, receive payment of
a proportion of the aggregate amount of principal and interest due with respect
to any Note held by it which is greater than the proportion received by any
other Bank in respect of the aggregate amount of principal and interest due with
respect to any Note held by such other Bank (other than disproportionate
payments to any Bank provided for by this Agreement), the Bank receiving such
proportionately greater payment shall purchase such participations in the Notes
held by the other Banks, and such other adjustments shall be made, as may be
required so that all such payments of principal and interest with respect to the
Notes held by the Banks shall be shared by the Banks pro rata; provided that
                                                               --------     
nothing in this Section shall impair the right of any Bank to exercise any right
of setoff or counterclaim it may have and to apply the amount recovered thereby
to the payment of indebtedness of the Borrower other than its indebtedness under
the Notes.  If under any applicable bankruptcy, insolvency or other similar law,
any Bank receives a secured claim in lieu of a setoff to which this Section
applies, such Bank shall, to the extent practicable, exercise its rights in
respect of such secured claim in a manner consistent with the rights of the
Banks entitled under this Section to share in the benefits of any recovery on
such secured claim.  The Borrower agrees, to the fullest extent it may
effectively do so under applicable law, that any holder of a participation in a
Note, whether or not acquired pursuant to the foregoing arrangements, may
exercise rights of setoff or counterclaim and other rights with respect to such
participation as fully as if such holder of a participation were a direct
creditor of the Borrower in the amount of such participation.

     SECTION 9.12.  Collateral.  Each of the Banks represents to the Agent and
                    ----------                                                
each of the other Banks that it in good faith is not relying upon any "margin
stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

     SECTION 9.13.  Consent to Jurisdiction.  (a)  The Borrower irrevocably
                    -----------------------                                
submits to the jurisdiction of any federal or Illinois state court sitting in
Chicago, Illinois over any suit, action or proceeding arising out of or relating
to this Agreement or any Note.  The Borrower irrevocably waives, to the fullest
extent permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in such court
and any claim that any suit, action or proceeding brought in such court has been
brought in an inconvenient forum. The Borrower agrees that a final judgment in
any such suit, action or proceeding brought in such a court shall be conclusive
and binding upon the Borrower and may be enforced in any federal or Illinois
state court sitting in Chicago, Illinois (or any other courts to the
jurisdiction of which the Borrower is or may be subject) by a suit upon such
judgment, provided that service of process is effected upon the Borrower in one
of the manners specified in subsection (b) of this Section or as otherwise
permitted by law.

     (b)  Service of Process.  The Borrower hereby consents to process being
          ------------------                                                
served in any suit, action or proceeding referred to in the first sentence of
subsection (a) of this Section in any federal or Illinois state court sitting in
Chicago, Illinois by mailing a copy thereof by registered or certified air mail,
postage prepaid, return receipt requested, to the Borrower at its address
specified in Section 9.01 or to any other address of which the Borrower shall
have given written notice to the Agent.  The Borrower irrevocably waives, to the
fullest extent permitted by law, all claim of error by reason of any such
service in any such suit, action or proceeding brought by the Agent or any Bank.
The Borrower agrees that such service shall be deemed in every respect effective
service of process upon the Borrower in any such suit, action or proceeding and
shall, to the fullest extent permitted by law, be taken and held to be valid and
personal service upon and personal delivery to the Borrower.

     (c)  No Limitation on Service or Suit.  Nothing in this Article shall
          --------------------------------                                
affect the right of the Agent or any Bank to serve process in any other manner
permitted by law or limit the right of the Agent or any Bank to bring
proceedings against the Borrower in the courts of the jurisdiction of the Bank's
Applicable Lending Office or the courts of any jurisdiction or jurisdictions in
which the Borrower has any assets.

     SECTION 9.14.  Waiver of Jury Trial.  THE AGENT, THE BANKS AND THE BORROWER
                    --------------------                                        
HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER BANK CREDIT DOCUMENT,
OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR
WRITTEN), OR ACTIONS OF THE AGENT, THE BANKS, OR THE BORROWER.

The Borrower promises to pay interest on the unpaid principal amount of each

                                                                    --------
that the failure of the Bank to make any such recordation or endorsement shall
not affect the obligations of the Borrower hereunder or under the Credit
Agreement.

To the Banks and the Agent
  Referred to Below
c/o The First National Bank
  of Chicago, as Agent
One First National Plaza
Chicago, Illinois 60670

Ladies and Gentlemen:

     I am [General Counsel] [Associate General Counsel-Corporate] of ARCO
Chemical Company (the "Borrower") and as such have acted as counsel, or
supervised attorneys who have acted as counsel, for the Borrower in connection
with Credit Agreement A, dated as of July 23, 1997 (the "Credit Agreement"),
among ARCO Chemical Company, the banks listed on the signature pages thereof,
and The First National Bank of Chicago, as Agent. Capitalized terms used but not
otherwise defined herein have the meanings assigned to such terms in the Credit
Agreement.

     I have examined originals or copies, certified or otherwise identified to
my satisfaction, of such documents, corporate records, certificates of public
officials and other instruments and have conducted such other investigations of
fact and law as I have deemed necessary or advisable for purposes of this
opinion.

     Upon the basis of the foregoing, I am of the opinion that:

     1.  (a)  The Borrower (i) is a corporation duly incorporated, validly
existing and in good standing under the laws of Delaware and (ii) either is
qualified to do business and in good standing in each jurisdiction where the
ownership of its properties or the conduct of its business requires such
qualification or is subject to no material liability or disability by reason of
the failure to be so qualified in any such jurisdiction.

     (b)  The Borrower has all corporate powers and authority, governmental
permits, licenses, consents, authorizations, orders and approvals and other
authorizations as are necessary to carry on its business substantially as
presently conducted except for such of the foregoing the absence of which would
not, in the aggregate, subject the Borrower to any material liability or
disability.
<PAGE>
 
     (c)  The execution, delivery and performance by the Borrower of the Credit
Agreement and the Notes, and Borrowings under the Credit Agreement by the
Borrower, are within the corporate power and authority of the Borrower and have
been duly authorized by all necessary corporate proceedings by the Borrower.

     (d)  Neither such authorization nor the execution, delivery and performance
by the Borrower of the Credit Agreement or of the Notes, nor any Borrowing by
the Borrower when made, will conflict with, result in a breach of or constitute
a default under any of the terms, conditions or provisions of any law or any
regulation, order, writ, injunction or decree of any court or governmental
authority or of the Certificate of Incorporation or By-Laws of the Borrower or
result in the violation or contravention of, or the acceleration of any
obligation under, or cause the creation of any Lien on any of the properties of
the Borrower pursuant to the provisions of, any indenture, agreement or other
instrument to which it is a party or by which it is bound.

     (e)  Assuming its due execution by the Banks and the Agent, the Credit
Agreement constitutes a legal, valid and binding agreement of the Borrower and
the Notes, when duly executed on behalf of the Borrower and delivered in
accordance with the Credit Agreement, will constitute legal, valid and binding
obligations of the Borrower enforceable in accordance with their respective
terms (subject, as to enforcement of remedies, to applicable bankruptcy,
reorganization, insolvency, moratorium or other laws affecting creditors' rights
generally from time to time in effect and to general principles of equity).

     2.  Except as previously disclosed in writing to the Banks prior to July
23, 1997, there is no action, suit or proceeding pending or, to my knowledge,
threatened against or affecting the Borrower or any of its subsidiaries in any
court or before or by any arbitrator, governmental department, agency or
instrumentality (i) which is likely to have a material adverse effect upon the
Borrower's ability to pay and perform its obligations under the Bank Credit
Documents in accordance with their respective terms or (ii) which in any manner
draws into question the validity of any of the Bank Credit Documents.  In this
regard, the Borrower has brought to your attention the Borrower's annual report
on Form 10-K for the year ended December 31, 1996, and the Borrower's quarterly
report on Form 10-Q for the three months ended March 31, 1997.

     3.  No consent, authorization, order or approval of (or filing or
registration with) any governmental commission, board or other regulatory
authority (other than routine reporting requirements) is required for the
execution, delivery and performance by the Borrower of the Credit Agreement or
the Notes or for Borrowings under the Credit Agreement.

     4.  The Borrower is not an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

     5.  The Cross-Indemnification Agreement, as amended to the date hereof, and
the Tax Sharing Agreement are in full force and effect in accordance with their
respective terms.

     6.  Each of the Borrower's Subsidiaries that is a corporation is duly
incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has all corporate powers and all governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted except for licenses, authorizations, consents or
approvals the absence of which will not materially and adversely affect the
business of the Borrower and its Consolidated Subsidiaries taken as a whole.

     I am counsel admitted to practice in the Commonwealth of Pennsylvania.  In
giving the foregoing opinion, I express no opinion as to the effect (if any) of
any laws of any jurisdiction other than the general corporate laws of the State
of Delaware and the laws of the Commonwealth of Pennsylvania.  I have assumed
for the purposes of this opinion that the applicable laws of the State of
Illinois are the same as the laws of the Commonwealth of Pennsylvania.

                    Very truly yours,

                      ASSIGNMENT AND ASSUMPTION AGREEMENT



     AGREEMENT dated as of __________, 19__ among [ASSIGNOR] (the "Assignor"),
[ASSIGNEE] (the "Assignee"), ARCO CHEMICAL COMPANY (the "Company") and THE FIRST
NATIONAL BANK OF CHICAGO, as Agent (the "Agent").


                                   WITNESSETH

     WHEREAS, this Assignment and Assumption Agreement (the "Agreement") relates
to Credit Agreement A dated as of July 23, 1997 among the Company, the Assignor
and the other Banks party thereto, as Banks, and the Agent (the "Credit
Agreement");

     WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans in an aggregate principal amount at any time
outstanding not to exceed $_______________;

     WHEREAS, Syndicated Loans made by the Assignor under the Credit Agreement
in the aggregate principal amount of $__________ are outstanding at the date
hereof; and

     WHEREAS, the Assignor proposes to assign to the Assignee all of the rights
of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $___________ (the "Assigned
Amount"), together with a corresponding portion of its outstanding Syndicated
Loans, and the Assignee proposes to accept assignment of such rights and assume
the corresponding obligations from the Assignor on such terms;

     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
contained herein, the parties hereto agree as follows:

     SECTION 1.  Definitions.  All capitalized terms not otherwise defined
                 -----------                                              
herein shall have the respective meanings set forth in the Credit Agreement.

     SECTION 2.  Assignment.  The Assignor hereby assigns and sells to the
                 ----------                                               
Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount, and the Assignee hereby accepts such assignment
from the Assignor and assumes all of the obligations of the Assignor under the
Credit Agreement to the extent of the Assigned Amount, including the purchase
from the Assignor of the corresponding portion of the principal amount of the
Syndicated Loans made by the Assignor outstanding at the date hereof.  Upon the
execution and delivery hereof by the Assignor, the Assignee, the Company and the
Agent and the payment of the amounts specified in Section 3 required to be paid
on the date hereof (i) the Assignee shall,
<PAGE>
 
as of the date hereof, succeed to the rights and be obligated to perform the
obligations of a Bank under the Credit Agreement with a Commitment in an amount
equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as
of the date hereof, be reduced by a like amount and the Assignor released from
its obligations under the Credit Agreement to the extent such obligations have
been assumed by the Assignee.  The assignment provided for herein shall be
without recourse to the Assignor.

     SECTION 3.  Payments.  As consideration for the assignment and sale
                 --------                                               
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds an amount equal to $__________*.  It is understood
that facility fees with respect to the Assigned Amount accrued to the date
hereof are for the account of the Assignor and such fees accruing from and
including the date hereof are for the account of the Assignee.  Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under the
Credit Agreement which is for the account of the other party hereto, it shall
receive the same for the account of such other party to the extent of such other
party's interest therein and shall promptly pay the same to such other party.

     SECTION 4.  Consent of the Company and the Agent.  This Agreement is
                 ------------------------------------                    
conditioned upon the consent of the Company and the Agent pursuant to Section
9.07(c) of the Credit Agreement.  The execution of this Agreement by the Company
and the Agent is evidence of this consent.  Pursuant to Section 9.07(c) the
Company agrees to execute and deliver a Note payable to the order of the
Assignee to evidence the assignment and assumption provided for herein.**



____________
*    Amount should combine principal together with accrued interest and breakage
     compensation, if any, to be paid by the Assignee, net of any portion of any
     upfront fee to be paid by the Assignor to the Assignee. It may be
     preferable in an appropriate case to specify these amounts generically or
     by formula rather than as a fixed sum.

**   Delete this Section 4 if no consent is required pursuant to Section 9.07(c)
     of the Credit Agreement.

                                    Page 2
<PAGE>
 
     SECTION 5.  Non-Reliance on Assignor.  The Assignor makes no representation
                 ------------------------                                       
or warranty in connection with, and shall have no responsibility with respect
to, the solvency, financial condition, or statements of the Borrower, or the
validity and enforceability of the obligations of the Borrower in respect of the
Credit Agreement or any Note.  The Assignee acknowledges that it has,
independently and without reliance on the Assignor, and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and will continue to be responsible for
making its own independent appraisal of the business, affairs and financial
condition of the Borrower.  Neither the Assignor nor any of its officers,
directors, employees, agents or attorneys shall be liable for any mistake, error
of judgment, or action taken or omitted to be taken in connection with any
Loans, Note, Commitment or other interest under the Credit Agreement.

     SECTION 6.  Governing Law.  This Agreement shall be governed by and
                 -------------                                          
construed in accordance with the laws of the State of Illinois.

     SECTION 7.  Counterparts.  This Agreement may be signed in any number of
                 ------------                                                
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
and delivered by their duly authorized officers as of the date first above
written.

The First National Bank of Chicago, as
  Agent, and the other financial institutions
  which are parties to each of the Credit
  Agreements referred to below

   Re: ARCO Chemical Company
       ---------------------

Ladies and Gentlemen:

   We have acted as special counsel to The First National Bank of Chicago, as
Agent (in such capacity, the "Agent"), in connection with Credit Agreement A and
Credit Agreement B (collectively, the "Credit Agreements"), each dated as of
July 23, 1997, among ARCO Chemical Company (the "Borrower"), various financial
institutions, and the Agent.  Capitalized terms used herein and not otherwise
defined shall have the meanings attributed to them in each of the Credit
Agreements.

   In connection herewith, we have examined counterparts of each Credit
Agreement executed by the Borrower, each of the Banks and the Agent; and each
Note issued by the Borrower on the date hereof pursuant to the Credit Agreements
(the "Notes").  In connection with such examination, we have assumed the
genuineness of all signatures, the authority of the persons signing such
documents and the authenticity of such documents.  We also have assumed, without
any independent investigation, that (a) each Credit Agreement and each Note has
been duly authorized, executed and delivered by each of the parties thereto and
(b) each Credit Agreement is the legal, valid and binding obligation of each
party thereto other than the Borrower, enforceable against each such party in
accordance with its terms.

   Based upon the foregoing, and subject to the qualifications set forth below,
we are of the opinion that, under the laws of the State of Illinois:
 
     (1)  Each Credit Agreement is the legal, valid and binding obligation of
          the Borrower, enforceable against the Borrower in accordance with its
          terms.

     (2)  The Notes are the legal, valid and binding obligations of the
          Borrower, enforceable against the Borrower in accordance with their
          terms.
<PAGE>
 
________, 1997
Page 2

   Our opinions are subject to the following qualifications:

   (a) Our opinions are subject to the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or similar law
affecting creditors' rights generally and to the effect of general principles of
equity (regardless of whether considered in a proceeding in equity or at law),
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing.

   (b) We express no opinion as to indemnification or contribution obligations
which contravene public policy.

   (c) We express no opinion as to any provision of either Credit Agreement
purporting to convey rights to Persons other than parties to such Credit
Agreement.

   (d) We express no opinion as to any waiver of (i) the right to a jury trial,
(ii) any objection to venue or (iii) any right to bring legal proceedings in any
court having jurisdiction.

   (e) Our opinions are limited to the laws of the State of Illinois, and we
express no opinion as to the laws of any other jurisdiction.

   This opinion letter is solely for the benefit of the addressees hereof (and
their respective successors and assigns) in connection with the transactions
contemplated by the Credit Agreements, and this opinion letter may not be relied
upon by any other Person or for any other purpose.

                             Very truly yours,

The Borrower may request offers to make Money Market Loans for more than one

          (B)  the principal amount of each Money Market Loan for which each
     such offer is being made, (w) the Dollar Amount of which principal amount
     may be greater or less than the Commitment of the quoting Bank, (x) which

     thereof) or a larger multiple of $1,000,000 (or the Approximate Equivalent
     Amount thereof), (y) which principal amount may not exceed in the aggregate

     maximum principal amount of Money Market Loans for which offers being made
     by such quoting Bank may be accepted;

     base rate;

A Money Market Quote may set forth up to five separate offers by the quoting

          (A)  is not substantially in the form of Exhibit D hereto or does not
     specify all of the information required by subsection (d)(ii) of this
     Section;

          (B)  contains qualifying, conditional or similar language;

          (C)  proposes terms other than or in addition to those set forth in

     (e)  The Agent shall promptly notify the Borrower of the terms (i) of any
Money Market Quote submitted by a Bank that is in accordance with subsection (d)
of this Section and (ii) of any subsequent Money Market Quote that amends,
modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market Quote Request;

Agent unless such subsequent Money Market Quote is submitted solely to correct a
manifest error in such former Money Market Quote.  The Agent's notice to the
Borrower shall specify (x) the aggregate principal amount and currency of Money
Market Loans for which offers have been received for each Interest Period
specified in the related Money Market Quote Request, (y) the respective
principal amounts and Money Market Margins or Money Market Rates, as the case
may be, so offered and (z) if applicable, limitations on the aggregate principal
amount of Money Market Loans for which offers in any single Money Market Quote
may be accepted.

     (f)  Not later than (x) 5:00 p.m., London time, on the fourth Euro-Currency
business Day prior to the proposed date of Borrowing, in the case of a LIBOR
Auction in a Designated Currency other than Dollars, (y) 10:00 a.m., Chicago

Borrowing, in the case of a LIBOR Auction in Dollars, or (z) 10:00 a.m., Chicago
time, on the proposed date of Borrowing, in the case of an Absolute Rate Auction
(or, in any such case, such other time and date as the Borrower and the Agent
shall have mutually agreed upon and shall have notified the Banks of not later
than the date of the Money Market Quote Request for the first LIBOR Auction or
Absolute Rate Auction for which such change is to be effective), the Borrower
shall notify the Agent of its acceptance or non-acceptance of the offers so
notified to it pursuant to subsection (e) of this Section.  In the case of
acceptance, such notice (a "Notice of Money Market Borrowing") shall specify the
aggregate principal amount of offers for each Interest Period that are accepted.
The Borrower may accept any Money Market Quote in whole or in part; provided
                                                                    --------
that:

          (i)    the aggregate principal amount of each Money Market Borrowing
     may not exceed the applicable amount set forth in the related Money Market
     Quote Request;

          (ii)   the principal amount of each Money Market Borrowing must be at
     least $10,000,000 (or the Approximate Equivalent Amount thereof) or a
     larger multiple of $1,000,000 (or the Approximate Equivalent Amount
     thereof); provided that upon giving effect to such Borrowing, the then
               --------                                                    
     aggregate outstanding principal Dollar Amount of all Syndicated Loans and
     all Money Market Loans shall not exceed the aggregate amount of the
     Commitments then in effect;

          (iii)  acceptance of offers for each Interest Period may only be made
     on the basis of ascending Money Market Margins or Money Market Rates, as
     the case may be; and

          (iv)   the Borrower may not accept any offer that is described in
     subsection (d)(iii) of this Section or that otherwise fails to comply with
     the requirements of this Agreement.

                                      19

     (g)  If offers are made by two or more Banks with the same Money Market
Margins or Money Market Rates, as the case may be, for a greater aggregate
principal amount of Money Market Loans than can be accepted for the related
Interest Period (after giving effect to the acceptance of all lower Money Market
Margins or Money Market Rates, as the case may be, properly offered for such
Interest Period), the principal amount of Money Market Loans which can be
accepted shall be allocated by the Agent among such Banks as nearly as possible
(in such multiples, not greater than $1,000,000 (or the Approximate Equivalent
Amount thereof), as the Agent may deem appropriate) in proportion to the
aggregate principal amount of such offers.  Determinations by the Agent of the
amounts of Money Market Loans by each Bank shall be conclusive in the absence of
manifest error.

     SECTION 2.04.  Notice to Banks; Funding of Loans. (a) Upon receipt of a
                    ---------------------------------                       
Notice of Borrowing, the Agent shall promptly notify each Bank of the contents
thereof and of such Bank's ratable share (if any) of such Borrowing and such
Notice of Borrowing shall not thereafter be revocable by the Borrower except
pursuant to subsection (d) of this Section or Section 8.01(a).

     (b)  On the date of each Borrowing, each Bank participating therein shall
(except as provided in subsection (c) of this Section) make available its
ratable share of such Borrowing, (i) if such Borrowing is denominated in
Dollars, not later than 12:00 noon, Chicago time, in Federal or other funds
immediately available to the Agent, in Chicago, Illinois at its address
specified in or pursuant to Section 10.01 and, (ii) if such Borrowing is
denominated in another currency, not later than 12:00 noon, local time in the
city of the Agent's Euro-Currency Payment Office for such currency, in such
funds as may then be customary for the settlement of international transactions
in such currency in the city of and at the address of the Agent's Euro-Currency
Payment Office for such currency. Unless the Agent determines that any
applicable condition specified in Article III has not been satisfied, the Agent
will make the funds so received from the Banks available to the Borrower at the
Agent's aforesaid address.

     (c)  If any Bank makes a new Loan hereunder on the date on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank,
which outstanding Loan is denominated in the currency of such new Loan, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the principal amount being repaid shall be made available by such Bank to the
Agent as provided in subsection (b) of this Section or remitted by the Borrower
to the Agent as provided in Section 2.12, as the case may be.

     (d)  Notwithstanding the satisfaction of all conditions referred to in
Section 2.01, 2.02 or 2.03(b) with respect to any Borrowing in any currency
other than Dollars, if there shall occur on or prior to the date of such
Borrowing any change in national or international financial, political or
economic conditions or currency exchange rates or exchange controls which would
in the opinion of the Agent or the Required Banks make it impracticable for the
Euro-Currency Loans or Money Market LIBOR Loans comprising such Borrowing to be
denominated in the currency specified by the Borrower, then the Agent shall
forthwith give notice thereof to the Borrower and the Banks, and such Loans
shall not be denominated in such currency but shall be made on the date of such

                                      20
<PAGE>
 
Borrowing in Dollars, in an aggregate principal amount equal to the Dollar
Amount of the aggregate principal amount specified in the related Notice of
Borrowing, as Base Rate Loans, unless the Borrower notifies the Agent at least
one Domestic Business Day before such date that (i) it elects not to borrow on
such date or (ii) it elects to borrow on such date in a different Agreed
Currency or Designated Currency, as the case may be, in which the denomination
of such Loans would in the opinion of the Agent and the Required Banks be
practicable and in an aggregate principal amount equal to the Dollar Amount of
the aggregate principal amount specified in the related Notice of Borrowing.

     SECTION 2.05.  Notes.  (a) The Loans of each Bank to the Borrower shall be
                    -----                                                      
evidenced by a single Note of the Borrower payable to the order of such Bank for
the account of its Applicable Lending Office in an amount equal to the aggregate
unpaid principal amount of such Bank's Loans to the Borrower.

     (b)  Each Bank may, by notice to the Borrower and the Agent (to be given
not later than two Domestic Business Days prior to the first Borrowing) request
that its Loans of a particular type be evidenced by a separate Note in an amount
equal to the aggregate unpaid principal amount of such Loans.  Each such Note
shall be in substantially the form of Exhibit A hereto with appropriate
modifications to reflect the fact that it evidences solely Loans of the relevant
type.  Each reference in this Agreement to a "Note" or the "Notes" of such Bank
shall be deemed to refer to and include any or all of such Notes, as the context
may require.

     (c)  Upon receipt of each Bank's Note(s) pursuant to Section 3.01(vi), the
Agent shall mail such Note(s) to such Bank.  Each Bank shall record, and prior
to any transfer of its Note(s) shall endorse on the schedules forming a part
thereof appropriate notations to evidence, the date, currency, amount and
maturity of each Loan made by it to the Borrower and the date and amount of each
payment of principal made by the Borrower with respect thereto; provided that
                                                                --------     
the failure of any Bank to make any such recordation or endorsement shall not
affect the obligations of the Borrower hereunder or under the Notes.  Each Bank
is hereby irrevocably authorized by the Borrower so to endorse the Notes and to
attach to and make a part of any such Note a continuation of any such schedule
as and when required.

     SECTION 2.06.  Maturity of Loans.  Each Loan included in any Borrowing
                    -----------------                                      
shall mature, and the principal amount thereof shall be due and payable, on the
last day of the Interest Period applicable to such Borrowing.

     SECTION 2.07.  Interest Rates.  (a) Each Base Rate Loan shall bear interest
                    --------------                                              
on the outstanding principal amount thereof, for each day from the date such
Loan is made until it becomes due at a rate per annum equal to the Base Rate for
such day.  Such interest shall be payable for each Interest Period on the last
day thereof.  Any overdue principal of and, to the extent permitted by law,
overdue interest on any Base Rate Loan shall bear interest, payable on demand,
for each day until paid at a rate per annum equal to the sum of 1% plus the rate
otherwise applicable to Base Rate Loans for such day.

                                      21
<PAGE>
 
     (b)  Each Euro-Currency Loan shall bear interest on the outstanding
principal amount thereof, for the Interest Period applicable thereto, at a rate
per annum equal to the sum of the applicable Syndicated Margin plus the
applicable London Interbank Offered Rate.  Such interest shall be payable for
each Interest Period on the last day thereof and, if such Interest Period is
longer than three months, at intervals of three months after the first day
thereof.

     The "London Interbank Offered Rate" applicable to any Interest Period for
any Euro-Currency Loan or Money Market LIBOR Loan shall mean the average
(rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective
rates per annum at which deposits in the currency in which such Euro-Currency
Loan or Money Market LIBOR Loan is denominated are offered to each of the
Reference Banks in the London interbank market at approximately 11:00 a.m.,
London time, two Euro-Currency Business Days before the first day of such
Interest Period, in an amount approximately equal to (i) the principal amount of
the Euro-Currency Loan or Money Market LIBOR Loan of such Reference Bank to
which such Interest Period is to apply or (ii) if such Reference Bank is not
submitting a Money Market Quote for such Money Market LIBOR Loan, $10,000,000
(or the Approximate Equivalent Amount thereof), and for a period of time
comparable to such Interest Period; provided that (i) for Euro-Currency Loans
                                    --------                                 
denominated in pounds sterling the respective rates per annum at which deposits
in pounds sterling are offered to each of the Reference Banks shall be the rate
for euro-sterling deposits not domestic sterling deposits and (ii) for Money
Market LIBOR Loans denominated in pounds sterling the respective rates per annum
at which deposits in pounds sterling are offered to each of the Reference Banks
shall be the rates for euro-sterling or domestic sterling deposits as specified
by the Borrower in the relevant Money Market Quote Request.

     (c)  Any overdue principal of and, to the extent permitted by law, overdue
interest on any Euro-Currency Loan shall bear interest, payable on demand, for
each day from and including the date payment thereof was due to but excluding
the date of actual payment, at a rate per annum equal to the sum of 1% plus the
applicable Syndicated Margin plus the average (rounded upward, if necessary, to
the next higher 1/16 of 1%) of the respective rates per annum at which one day
(or, if such amount due remains unpaid more than three Euro-Currency Business
Days, then for such other period of time not longer than three months as the
Agent may elect) deposits in the relevant currency in an amount approximately
equal to such overdue payment due to each of the Reference Banks are offered to
such Reference Bank in the London interbank market for the applicable period
determined as provided above (or, if the circumstances described in clause (a)
or (b) of Section 8.01 shall exist, at a rate per annum equal to the sum of (i)
if such Euro-Currency Loan is denominated in Dollars, 1% plus the rate
applicable to Base Rate Loans for such day and (ii) if such Euro-Currency Loan
is denominated in any other currency, 1% plus the cost to such Bank of funding
or maintaining such Euro-Currency Loan).  The certificate of such Bank as to the
cost of funding or maintaining such Euro-Currency Loan shall be conclusive
absent manifest error.

     (d)  Subject to Section 8.01(a)(1), each Money Market LIBOR Loan shall bear
interest on the outstanding principal amount thereof, for the Interest Period
applicable thereto, at a rate per annum

                                      22
<PAGE>
 
equal to the sum of the London Interbank Offered Rate for such Interest Period
(determined in accordance with subsection (c) of this Section as if each
Reference Bank were to participate in the related Money Market Borrowing ratably
in proportion to its Commitment) plus (or minus) the Money Market Margin quoted
by the Bank making such Loan in accordance with Section 2.03.  Each Money Market
Rate Loan shall bear interest on the outstanding principal amount thereof, for
the Interest Period applicable thereto, at a rate per annum equal to the Money
Market Rate quoted by the Bank making such Loan in accordance with Section 2.03.
Such interest shall be payable for each Interest Period on the last day thereof.
Any overdue principal of and, to the extent permitted by law, overdue interest
on any Money Market Loan shall bear interest, payable on demand, for each day
until paid at a rate per annum equal to the sum of (i) if such Money Market Loan
is denominated in Dollars, 1% plus the rate applicable to Base Rate Loans for
such day and (ii) if such Money Market Loan is denominated in any other
currency, 1% plus the cost to such Bank of funding or maintaining such Money
Market Loan.  The certificate of such Bank certifying the cost of funding or
maintaining such Money Market Loan shall be conclusive absent manifest error.

     (e)  The Agent shall determine each interest rate applicable to the Loans
hereunder.  The Agent shall give prompt notice to the Borrower and the
participating Banks by telex or facsimile transmission of each rate of interest
so determined, and its determination thereof shall be conclusive in the absence
of manifest error.

     (f)  Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section.  If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available on
a timely basis, the provisions of Section 8.01 shall apply.

     SECTION 2.08.  Fees.  (a)  The Borrower shall pay to the Agent for the
                    ----                                                   
account of the Banks ratably in proportion to their Commitments a facility fee
at a rate per annum equal to the applicable Facility Fee Percentage on the daily
average amount of the Commitments (without regard to the outstanding principal
amount of the Loans).  Such facility fee shall accrue from and including July
23, 1997 to but excluding the Termination Date.

     (b)  The Borrower shall pay to each of the Agent and the Arranger for its
own account fees in the amounts and at the time previously agreed upon between

quarterly in arrears on the fifth Domestic Business Day after each Quarterly
Date for the quarter ending on such Quarterly Date or, if earlier, the fifth
Domestic Business Day after the date of termination of the Commitments in their
entirety.

     SECTION 2.09.  Optional Termination or Reduction of Commitments.
                    ------------------------------------------------

     (a) The Borrower may, upon at least two Domestic Business Days' irrevocable
notice to the Agent, terminate at any time, or reduce from time to time by an
aggregate amount of $10,000,000 or a larger multiple of $1,000,000 the aggregate
amount of the Commitments in excess of the Dollar Amount of the aggregate
outstanding principal amount of the Loans.

     (b) In the absence of a Default that has occurred and is continuing and in
the event that (i) any Bank claims indemnification pursuant Section 2.16(a) or
Section 2.16(b), (ii) the Borrower is required to make an additional payment to
any Bank pursuant to Section 2.16(a), or (iii) any Bank makes a claim for
increased costs relating to taxes under Section 8.03, the Borrower shall have
the right to repay all of such Bank's outstanding Loans and to terminate such
Bank's Commitment hereunder upon ten days prior written notice to the Agent and
such Bank. On the day on which any Bank's Commitment is terminated pursuant to
this Section 2.09(b), the Borrower shall pay all principal, accrued interest,
fees and other amounts owing to such Bank hereunder (including, without
limitation, any amounts owing under Sections 2.08, 2.13, 2.16, and 8.03).

     SECTION 2.10.  Mandatory Termination of Commitments.  The Commitments shall

terminate on the Termination Date, and any Loans outstanding on the Termination
Date shall be due and payable on the Termination Date (together with accrued
interest thereon).

     SECTION 2.11.  Optional Prepayments.  (a) The Borrower may prepay any Base

Rate Borrowing (or any Money Market Borrowing bearing interest at the Base Rate
pursuant to Section 8.01(a)) upon at least one Domestic Business Day's notice to
the Agent or, subject to Section 2.13, prepay any Euro-Currency Borrowing upon
at least two Euro-Currency Business Days' notice to the Agent, in any such case
in whole at any time, or from time to time in part in amounts aggregating
$10,000,000 (or the Approximate Equivalent Amount thereof) or any larger
multiple of $1,000,000 (or the Approximate Equivalent Amount thereof), by paying
the principal amount to be prepaid together with accrued interest thereon to the
date of prepayment.  Each such optional prepayment shall be applied to prepay
ratably the Loans of the several Banks included in such Borrowing.  The Borrower
may not prepay all or any portion of the principal amount of any Money Market
Loan (other than a Money Market LIBOR Loan bearing interest at the Base Rate
pursuant to Section 8.01(a)) prior to the maturity thereof.

     (b) Upon receipt of a notice of prepayment pursuant to this Section, the
Agent shall promptly notify each Bank of the contents thereof and of such Bank's
ratable share (if any) of such prepayment and such notice shall not thereafter
be revocable by the Borrower.

     SECTION 2.12.  General Provisions as to Payments.  (a) All payments to be
                    ---------------------------------                         
made by the Borrower hereunder or under the Notes in Dollars shall be made not
later than 12:00 noon, Chicago time, on the date when due, in Federal or other
funds immediately available in Chicago, Illinois, to the Agent at its address
referred to in Section 9.01.  The Agent will promptly distribute to each Bank
its ratable share of each such payment received by the Agent for the account of
the Banks.


                                      24
<PAGE>
 
     (b)  Each Borrowing shall be repaid or prepaid in the currency in which it
was made in the amount borrowed and interest payable thereon shall be paid in
such currency.  All payments to be made by the Borrower hereunder or under the
Notes in any currency other than Dollars shall be made in such currency on the
date due in such funds as may then be customary for the settlement of
international transactions in such currency for the account of the Agent, at its
Euro-Currency Payment Office for such currency.  The Agent will promptly cause
such payments to be distributed to each Bank in like funds and currency.
Notwithstanding the foregoing provisions of this Section, if, after the making
of any Loan in any currency other than Dollars, currency control or exchange
regulations are imposed in the country which issues such currency with the
result that different types of such currency (the "New Currency") are introduced
and the type of currency in which the Borrowing was made (the "Original
Currency") no longer exists or the Borrower is not able to make payment to the
Agent for the account of the Banks in such Original Currency, then all payments
to be made by the Borrower hereunder or under the Notes in such currency shall
be made in such amount and such type of the New Currency as shall be equivalent
to the amount of such payment otherwise due hereunder or under the Notes in the
Original Currency, it being the intention of the parties hereto that the
Borrower takes all risks of the imposition of any such currency control or
exchange regulations.  In addition, notwithstanding the foregoing provisions of
this Section, if, after the making of any Borrowing in any currency other than
Dollars, the Borrower is not able to make payment to the Agent for the account
of the Banks in the type of currency in which such Borrowing was made, then such
Borrowing shall instead be repaid when due in Dollars in a principal amount
equal to the Dollar Amount (as of the date of repayment) of such Borrowing.

     (c)  Whenever any payment of principal of, or interest on, the Base Rate
Loans or of additional compensation shall be due on a day which is not a
Domestic Business Day, the date for payment thereof shall be extended to the
next succeeding Domestic Business Day.  Whenever any payment of principal of, or
interest on, the Euro-Currency Loans shall be due on a day which is not a Euro-
Currency Business Day, the date for payment thereof shall be extended to the
next succeeding Euro-Currency Business Day unless such Euro-Currency Business
Day occurs in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Currency Business Day.  Whenever any payment of
principal of, or interest on, the Money Market Loans shall be due on a day which
is not a Euro-Currency Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Currency Business Day.  If the date for any
payment of principal is extended by operation of law or otherwise, interest
thereon shall be payable for such extended time.

     (d)  Unless the Agent shall have been notified by a Bank or the Borrower
(the "Payor") prior to the date on which such Bank is to make payment to the
Agent of the proceeds of a Loan to be made by it hereunder or the Borrower is to
make a payment to the Agent for the account of one or more of the Banks, as the
case may be (each of such payments being herein called a "Required Payment"),
which notice shall be effective upon receipt, that the Payor does not intend to
make the Required Payment to the Agent, the Agent may assume that the Required
Payment has been made and may (but shall not be required to), in reliance upon
such assumption, make the amount thereof available to the intended recipient on
such date and, if the Payor has not in fact made the Required

                                      25
<PAGE>
 
Payment to the Agent, the recipient of such payment shall, on demand, refund to
the Agent the amount made available to it together with interest thereon in
respect of the period commencing on the date such amount was so made available
by the Agent until the date the Agent recovers such amount at a rate equal to
the Federal Funds Rate for such period, if the recipient is a Bank, and, if the
recipient is the Borrower, the rate which the Borrower would have been obligated
to pay hereunder for the Loans that are the subject of, or are equivalent to,
such payment for such period.

     SECTION 2.13.  Funding Losses.  The Borrower shall pay to the Agent for the
                    --------------                                              
account of each Bank, upon the request of such Bank through the Agent, such
amount or amounts as shall compensate such Bank for any reasonable loss, cost or
expense incurred by such Bank (or, subject to Section 9.07(b), by an existing or
prospective Participant in the related Loan) as a result of:

          (a)  any payment or prepayment of a Fixed Rate Loan (pursuant to
     Section 2.11 or Article VI or VIII or otherwise)  held by such Bank on a
     date other than the last day of the Interest Period applicable thereto, or
     the end of an applicable period fixed pursuant to Section 2.07(c) or

          (b)  any failure by the Borrower to borrow a Fixed Rate Loan
     (including a failure to borrow due to the occurrence of any event described
     in Section 2.04(d)) held or to be held by such Bank on the date for such
     Borrowing specified in the relevant Notice of Borrowing under Section 2.02
     or 2.03(f), such compensation to be payable in the currency specified in
     the certificate referred to below and to include, without limitation, an
     amount equal to the excess, if any, of (i) the amount of interest which
     would have accrued on the amount so paid or prepaid, or not borrowed, for
     the period from the date of such payment or prepayment or failure to borrow
     to the last day of such Interest Period (or, in the case of a failure to
     borrow, the Interest Period for such Fixed Rate Loan which would have
     commenced on the date of such failure to borrow) in each case at the
     applicable rate of interest for such Fixed Rate Loan provided for herein
     (excluding, however, the Syndicated Margin or any positive Money Market
     Margin, as the case may be, included therein) over (ii) the amount of
     interest (as reasonably determined by such Bank) which would have accrued
     to such Bank on such amount by placing such amount on deposit for a
     comparable period with leading banks in the London interbank market or in
     the New York or Chicago certificate of deposit market; provided that such
                                                            --------          
     Bank shall have delivered to the Borrower, within 60 days after the date of
     such payment or prepayment or failure to borrow, a certificate as to the
     amount and currency of such loss or expense, which certificate shall set
     forth in reasonable detail the basis for such loss or expense and shall be
     conclusive in the absence of manifest error.

     SECTION 2.14.  Computation of Interest and Fees.  Interest based on the
                    --------------------------------                        
Base Rate and interest on Borrowings denominated in pounds sterling shall be
computed on the basis of a year of 365 days (or 366 days in a leap year) and
paid for the actual number of days elapsed (including the first day but
excluding the last day).  All other interest and fees shall be computed on the
basis of a year of 360 days and paid for the actual number of days elapsed
(including the first day but excluding the last day).

                                      26

     SECTION 2.15.  Judgment Currency.  If for the purposes of obtaining
                    -----------------                                   
judgment in any court it is necessary to convert a sum due from the Borrower
hereunder or under any of the Notes in the currency expressed to be payable
herein or under the Notes (the "specified currency") into another currency, the
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Agent could purchase the specified currency with such
other currency at the Agent's main Chicago office on the Euro-Currency Business
Day preceding that on which final, non-appealable judgment is given.  The
obligations of the Borrower in respect of any sum due to any Bank or the Agent
hereunder or under any Note shall, notwithstanding any judgment in a currency
other than the specified currency, be discharged only to the extent that on the
Euro-Currency Business Day following receipt by such Bank or the Agent (as the
case may be) of any sum adjudged to be so due in such other currency such Bank
or the Agent (as the case may be) may in accordance with normal, reasonable
banking procedures purchase the specified currency with such other currency.  If
the amount of the specified currency so purchased is less than the sum
originally due to such Bank or the Agent, as the case may be, in the specified
currency, the Borrower agrees, to the fullest extent that it may effectively do
so, as a separate obligation and notwithstanding any such judgment, to indemnify
such Bank or the Agent, as the case may be, against such loss, and if the amount
of the specified currency so purchased exceeds (a) the sum originally due to any
Bank or the Agent, as the case may be, in the specified currency and (b) any
amounts shared with other Banks as a result of allocations of such excess as a
disproportionate payment to such Bank under Section 9.11, such Bank or the
Agent, as the case may be, agrees to remit such excess to the Borrower.

     SECTION 2.16.  Taxes.  (a) All payments made by the Borrower in respect of
                    -----                                                      
principal of and interest on its Borrowings and of all other amounts payable by
it under this Agreement are payable without deduction for or on account of any
Taxes.  If the Borrower shall be required by law to deduct or withhold any Taxes
from any such amount payable by it hereunder or under any of the Notes to or for
the account of any Bank, (i) such amount shall be increased as may be necessary
so that, after making such deductions or withholdings (including any deductions
or withholdings applicable to additional amounts payable pursuant to this
Section), such Bank receives an amount equal to the amount it would have
received had no such deductions or withholdings been made and (ii) the Borrower
shall make such deductions and withholdings and pay the amount thereof to the
relevant government, political subdivision or taxing authority at or prior to
the time required to be paid under applicable law (and shall promptly furnish to
the Agent, for the benefit of the Banks, official receipts evidencing such
payment).  In addition, the Borrower will pay any present or future stamp or
documentary taxes or similar taxes or levies imposed by any government of any
jurisdiction outside the United States of America or any  political subdivision
or taxing authority thereof from any payment by it hereunder or under any of the
Notes or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement or any of the Notes (herein called "Other Taxes").
The Borrower will indemnify each Bank and the Agent for, and hold each Bank and
the Agent harmless against, the full amount of Taxes or Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any jurisdiction on
amounts payable under this Section) paid or payable by such Bank or the Agent
and any liability of such Bank or the Agent relating thereto (including,

                                      27
<PAGE>
 
without limitation, penalties, interest and expenses).  Notwithstanding anything
set forth above in this clause (a), the Borrower shall have no obligation to
increase the amount payable to any Bank as a result of any deduction or
withholding, or to indemnify any Bank for or hold any Bank harmless against any
Taxes or Other Taxes, to the extent that such deduction or withholding would not
have been required, or such Taxes or Other Taxes would not have been paid or
payable, if such Bank's representation and warranty in clause (f) below had been
accurate or such Bank had complied with its obligations under clause (g) below.

     (b)  If the cost to any Bank of making or maintaining any Loan to the
Borrower is increased, or the amount of any sum received or receivable by any
Bank (or its Applicable Lending Office) is reduced, by an amount deemed by such
Bank to be material, which increase or reduction would not have occurred but for
the fact that the Borrower conducts business in a jurisdiction outside the
United States of America, the Borrower shall indemnify such Bank for such
increased cost or reduction within 15 days after demand by such Bank (with a
copy to the Agent).  A certificate of such Bank claiming indemnification under
this Section, setting forth the additional amount or amounts to be paid to it
hereunder and setting forth in reasonable detail a reasonable basis therefor,
shall be conclusive in the absence of manifest error.  In determining such
amount, such Bank may use any reasonable averaging and attribution methods.

     (c)  Each Bank will promptly notify the Borrower and the Agent of any event
of which it has knowledge that will entitle such Bank to any payment or
indemnification under clause (a) or (b) of this subsection and will designate a
different Domestic Lending Office, Money Market Lending Office or Euro-Currency
Lending Office, as the case may be, if such designation will avoid the need for,
or reduce the amount of, such payment or indemnification and will not, in the
sole opinion of such Bank, be otherwise materially disadvantageous to such Bank.

     (d)  If, and to the extent that, any Bank shall obtain a credit, relief or
remission for, or repayment of, any Taxes or Other Taxes indemnified or paid by
the Borrower pursuant to this Section or for any taxes for which Borrower has
made payments under Section 8.03, such Bank agrees to promptly notify the
Borrower thereof and thereupon enter into negotiations in good faith with the
Borrower to determine the basis on which an equitable reimbursement of such
taxes can be made to the Borrower.

     (e)  All tax receipts required to be delivered under this Section shall be
originals, duplicate originals or duly certified or authenticated copies within
the meaning of Treasury Regulation Section 1.905-2(a)(2).

     (f)  Each Bank represents and warrants to the Borrower and the Agent that,
as of the date of this Agreement (or, in the case of an Assignee, the date it
becomes a party hereto), it is entitled to receive payments hereunder without
any deduction or withholding for or on account of any Taxes imposed by the
United States of America or any political subdivision or taxing authority
thereof.

                                      28
<PAGE>
 
     (g)  Each Bank which is a Non-U.S. Person (and, if at any time the Agent
hereunder is a Non-U.S. Person, such Agent) agrees that it will, to the extent
it is able to do so under applicable law and treaties,

          (i)  within 30 days of the date of this Agreement (or, in the case of
     a Bank which becomes a party hereto pursuant to a transfer or assignment,
     on or prior to the date on which the relevant transfer or assignment
     becomes effective) deliver to the Borrower (and, in the case of a Bank, to
     the Agent) such forms (including two duly executed originals of United
     States Internal Revenue Form 1001 or 4224 or any successor to the
     applicable form), properly and accurately completed, as are necessary to
     claim complete or partial (as the case may be) exemption from withholding
     of United States federal taxes; and

          (ii) deliver extensions or renewals of such forms on or before the
     date that any such form expires or becomes obsolete, and after the
     occurrence of any event requiring  a change in the most recent form
     previously delivered by it, 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 Agent
     or Bank from duly completing and delivering any such form with respect to
     it and such Agent or Bank so advises the Borrower (and, in the case of a
     Bank, the Agent).

For purposes of the foregoing, a Non-U.S. Person means a Person that is not (i)
a citizen or resident of the United States, (ii) a corporation or partnership
created or organized under the laws of the United States or any state thereof or
(iii) an estate or trust the income of which is subject to United States federal
income taxation regardless of its source;

     SECTION 2.17.  Maximum Interest Rate.  (a) Nothing contained in this
                    ---------------------                                
Agreement or the Notes shall require the Borrower to pay interest at a rate
exceeding the maximum rate permitted by applicable law.

     (b)  If the amount of interest payable for the account of any Bank on any
interest payment date in respect of the immediately preceding interest
computation period, computed pursuant to Section 2.07, would exceed the maximum
amount permitted by applicable law to be charged by such Bank, the amount of
interest payable for its account on such interest payment date shall be
automatically reduced to such maximum permissible amount.

     (c)  If the amount of interest payable for the account of any Bank in
respect of any interest computation period is reduced pursuant to clause (b) of
this Section and the amount of interest payable for its account in respect of
any subsequent interest computation period, computed pursuant to Section 2.07,
would be less than the maximum amount permitted by applicable law to be charged
by such Bank, then the amount of interest payable for its account in respect of
such subsequent interest computation period shall be automatically increased to
such maximum permissible amount; provided that at no time shall the aggregate
                                 --------                                    
amount by which interest paid for the account of any

                                      29
<PAGE>
 
Bank has been increased pursuant to this clause (c) exceed the aggregate amount
by which interest paid for its account has theretofore been reduced pursuant to
clause (b) of this Section.

Bank to make any Loan to be made by it as a part of the initial Borrowing by the
Borrower hereunder is subject to the condition precedent that the Agent shall

     for and the validity of this Agreement and the Notes, and any other matters
     relevant hereto, all in form and substance satisfactory to the Agent;

          (ii)  a Certificate of Incumbency executed by the Secretary or an

     officer or representative duly authorized for that purpose, act as the

     giving notices and other communications by the Borrower in connection with
     this Agreement and the transactions contemplated hereby;

          (iii) an opinion of the General Counsel or, in his absence, the

Euro-Currency Business Days before the date of such initial Borrowing.

     SECTION 3.02.  Each Borrowing.  The obligation of each Bank to make each
                    --------------                                           
Loan to be made by it as part of a Borrowing hereunder to the Borrower is

          (i)   the Agent shall have received a Notice of Borrowing as required

     Refunding Borrowing, the representations and warranties set forth in
     clauses (d) and (e) of Section 4.01 as to any material adverse change or
     litigation, respectively, which has theretofore been disclosed in writing
     by the Borrower to the Banks).

Each Borrowing hereunder shall be deemed to be a representation and warranty by
the Borrower on the date of such Borrowing as to the facts specified in clauses

                        REPRESENTATIONS AND WARRANTIES

     SECTION 4.01.  Representations and Warranties of the Borrower.  The
                    ----------------------------------------------      
Borrower represents and warrants to the Banks as follows:

          (a)(1) The Borrower (i) is a corporation duly incorporated, validly
     existing and in good standing under the laws of the State of Delaware and
     (ii) either is qualified to do business and in good standing in each
     jurisdiction where the ownership of its properties or the conduct of its
     business requires such qualification or is subject to no material liability
     or disability by reason of the failure to be so qualified in any such
     jurisdiction.

          (2) The Borrower has all corporate power and authority, governmental
     permits, licenses, consents, authorizations, orders and approvals and other
     authorizations as are necessary to carry on its business substantially as
     presently conducted except for such of the foregoing the absence of which
     would not, in the aggregate, subject the Borrower to any material liability
     or disability.

          (3) The execution, delivery and performance of the Bank Credit
     Documents, and borrowings thereunder by the Borrower, are within its
     corporate power and authority and have been duly authorized by all
     necessary corporate proceedings.

          (4) Neither such authorization nor the execution, delivery and
     performance by the Borrower of the Bank Credit Documents, nor any borrowing
     thereunder by the Borrower when made, will conflict with, result in a
     breach of or constitute a default under any of the terms, conditions or
     provisions of any law or any regulation, order, writ, injunction or decree
     of any court or governmental authority or of the Certificate of
     Incorporation or By-Laws of the Borrower or result in the violation or
     contravention of, or the acceleration of any obligation under, or cause the
     creation of any Lien on any of the properties of the Borrower pursuant to
     the provisions of, any indenture, agreement or other instrument to which it
     is a party or by which it is bound.

          (5) Assuming their due execution by the Banks and the Agent, each of
     this Agreement and the Other Agreement constitutes a legal, valid and
     binding agreement of the Borrower, and the Notes (both as defined hereunder
     and under the Other Agreement), when duly executed on behalf of the
     Borrower and delivered in accordance with this Agreement and the Other
     Agreement, will constitute legal, valid and binding obligations of the
     Borrower (subject, as to enforcement of remedies, to applicable bankruptcy,
     reorganization, insolvency, moratorium or other laws affecting creditors'
     rights generally from time to time in effect and to general principles of
     equity).

          (b) The consolidated balance sheet of the Borrower and its
     Consolidated Subsidiaries as of December 31, 1996 and the related
     consolidated statements of income and changes in financial position for the
     12 months ended that date, certified by Coopers & Lybrand, copies of all of
     which have been delivered to the Banks, fairly present the consolidated
     financial position of the Borrower and its Consolidated Subsidiaries as of
     such date and the consolidated results of their operations and changes in
     financial position for such fiscal year, in conformity with GAAP
     consistently applied.

          (c) The unaudited consolidated balance sheet of the Borrower and its
     Consolidated Subsidiaries as of March 31, 1997 and the related unaudited
     consolidated statements of income and changes in financial position for the
     fiscal quarter then ended, a copy of which has been delivered to each of
     the Banks, fairly present, in conformity with GAAP applied on a basis
     consistent with the financial statements referred to in paragraph (b) of
     this Section, the consolidated financial position of the Borrower and its
     Consolidated Subsidiaries as of such date and their consolidated results of
     operations and changes in financial position for such fiscal quarter
     (subject to normal year-end adjustments).

          (d) Except as disclosed in writing to the Banks prior to July 23,
     1997, there has been no material adverse change since December 31, 1996 and
     prior to July 23, 1997, in the business, operations, affairs, assets,
     condition (financial or otherwise) or results of operations of the Borrower
     and its Consolidated Subsidiaries, considered as a whole.

          (e) Except as disclosed in writing to the Banks prior to July 23,
     1997, there is no action, suit or proceeding pending or, to the knowledge
     of the Borrower, threatened against or affecting the Borrower or any of its
     Subsidiaries in any court or before or by any arbitrator, governmental
     department, agency or instrumentality (i) which is likely to have a
     material adverse effect upon the Borrower's ability to pay and perform its
     obligations under the Bank Credit Documents in accordance with their
     respective terms or (ii) which in any manner draws into question the
     validity of any of the Bank Credit Documents.

          (f) No Default has occurred and is continuing.

          (g) No consent, authorization, order or approval of (or filing or
     registration with) any governmental commission, board or other regulatory
     authority (other than routine reporting requirements) is required for the
     execution, delivery and performance by the Borrower of any of the Bank
     Credit Documents or for borrowings thereunder by the Borrower.

          (h) Each member of the ERISA Group has fulfilled its obligations under
     the minimum funding standards of ERISA and the Code with respect to each
     Plan and is in compliance in all material respects with the presently
     applicable provisions of ERISA and the Code with respect to each Plan.  No
     member of the ERISA Group has (i) sought a waiver of the minimum funding
     standard under Section 412 of the Code in respect of any Plan, (ii) failed
     to make any contribution or payment to any Plan or Multiemployer Plan or in
     respect

                                      33
<PAGE>
 
     of any Benefit Arrangement, or made any amendment to any Plan or Benefit
     Arrangement, which has resulted or could result in the imposition of a Lien
     or the posting of a bond or other security under ERISA or the Code or (iii)
     incurred any liability under Title IV of ERISA other than a liability to
     the PBGC for premiums under Section 4007 of ERISA.

          (i) The Cross-Indemnification Agreement and the Tax Sharing Agreement,
     in the respective forms, with amendments, certified to the Banks pursuant
     to Section 3.01(iv), are in full force and effect in accordance with their
     respective terms except for (1) any amendments, modifications or waivers of
     the Tax Sharing Agreement which do not materially alter the rights and
     obligations of the Borrower thereunder which as a whole place the Borrower
     in the same (or more favorable) relative financial position with respect to
     the Parent which the Borrower would have been in if the Borrower were not
     consolidated with the Parent for purposes of filing federal, state or local
     or other income tax returns, (2) any amendments to the Cross-
     Indemnification Agreement for the purpose of placing the Borrower and the
     Parent in the same financial positions with respect to each other which
     they would have been in if the Borrower and the Parent were not members of
     the same ERISA Group, including the allocation of, and indemnification with
     respect to, assets and funded and unfunded liabilities among the Borrower,
     the Parent, Affiliates, Subsidiaries and their respective Plans in such
     manner as is fair and equitable to the Borrower and its Subsidiaries, (3)
     any amendments, modifications or waivers of the Cross-Indemnification
     Agreement or the Tax Sharing Agreement which do not, in the aggregate,
     materially reduce the rights of the Borrower thereunder against the Parent
     or materially increase the obligations of the Borrower thereunder to the
     Parent and (4) any other amendments, modifications or waivers of such
     instruments to which the Required Banks have consented.  True and complete
     copies of all such amendments, modifications and waivers have been
     delivered to the Agent for each of the Banks.  No amount that may be due
     under the Cross-Indemnification Agreement or the Tax Sharing Agreement from
     the Parent to the Borrower or to the Parent from the Borrower is
     delinquent, except such amount as the Borrower or the Parent may be
     contesting in good faith.

          (j) Each corporate Subsidiary is a corporation duly incorporated,
     validly existing and in good standing under the laws of its jurisdiction of
     incorporation, and has all corporate powers and all governmental licenses,
     authorizations, consents and approvals required to carry on its business as
     now conducted except for licenses, authorizations, consents or approvals
     the absence of which will not materially and adversely affect the business
     of the Borrower and its Consolidated Subsidiaries taken as a whole.

          (k) The Borrower is not an "investment company" within the meaning of
     the Investment Company Act of 1940, as amended.

          (l) There are no Liens on any asset of the Borrower or any Subsidiary
     on July 23, 1997 which would have been prohibited if Section 5.02 of this
     Agreement had been in effect on the date the Borrower or such Subsidiary,
     as the case may be, acquired such asset.

          (m) Except as disclosed in writing to the Banks, the description of
     environmental matters affecting the Borrower and its Subsidiaries contained
     in each of the Borrower's reports delivered to the Banks pursuant to clause
     (ii) of Section 5.01(c) complied in all material respects as of the date of
     such report with the requirements of the Securities Exchange Act of 1934,
     as amended, and the rules and regulations promulgated thereunder.

     knowledge of any Default, a certificate of the Treasurer or other financial
     officer specifying the nature and period of existence thereof and the
     action the Borrower is taking and proposes to take with respect thereto;

          (f) if and when any member of the ERISA Group (i) gives or is required

     results of operations of the Borrower and its Consolidated Subsidiaries as
     the Agent, at the request of any Bank, may reasonably request.

     SECTION 5.02.  Limitation on Liens.  Neither the Borrower nor any
                    -------------------                               
Subsidiary will issue, assume or guarantee any Debt secured by any Lien upon any
asset of the Borrower or any Subsidiary or grant any Lien on any such asset to
secure any such Debt without effectively providing that all of the Notes
(together with, if the Borrower so determines, any other Debt then existing and
any other Debt thereafter created ranking equally with the Notes) shall be
secured equally and ratably with (or prior to) such Debt so long as such Debt
shall be so secured.  To the extent the following Liens would otherwise be
prohibited by the foregoing provisions, the foregoing provisions shall not apply
to:

          (a) Liens on any asset of a corporation existing at the time it
     becomes a Subsidiary of the Borrower or at the time it is merged into or
     consolidated with the Borrower or a Subsidiary and not created in
     contemplation of such event;

          (b) Liens on property existing at the time of acquisition thereof or
     incurred to secure payment of all or part of the purchase price thereof or
     to secure Debt incurred prior to, at the time of or within 24 months after
     acquisition thereof for the purpose of financing all or part of the
     purchase price thereof;

          (c) Liens on any property to secure all or part of the cost of
     construction or improvements thereon or Debt incurred to provide funds for
     any such purpose in a principal amount not exceeding the cost of such
     construction or improvements;

          (d) Liens which secure only Debt owing by a Subsidiary to the Borrower
     or another Subsidiary;

          (e) Liens in favor of the United States of America or any state
     thereof or any department, agency, instrumentality or political subdivision
     of any such jurisdiction to secure partial, progress, advance or other
     payments pursuant to any contract or statute or to secure any Debt payable
     to the foregoing incurred for the purpose of financing all or any part of
     the purchase price or cost of constructing or improving the property
     subject to such Lien, including, without limitation, Liens to secure Debt
     in respect of any pollution control, industrial revenue bond or other
     similar type of financing;

          (f) Liens required by any contract or statute in order to permit the
     Borrower or a Subsidiary to perform any contract or subcontract made by it
     with or at the request of the United States of America, any state or any
     department, agency or instrumentality or political subdivision of either;

          (g) mechanics', suppliers', materialmen's and similar Liens arising in
     the ordinary course of business securing Debt which is not overdue or is

<PAGE>
 
     in good faith by appropriate action, promptly initiated and diligently
     conducted and in connection with which adequate reserves are being
     maintained;

          (h) Liens securing obligations of the Borrower or any Subsidiary to
     pay the deferred purchase price of services not exceeding in the aggregate
     $10,000,000;

          (i) the Lien of any judgment or attachment in respect of any Debt, so
     long as (1) the Borrower in good faith by appropriate action, promptly
     initiated and diligently conducted, shall contest or cause to be contested
     the validity, amount, extent or application thereof and (2) such action
     shall operate to prevent the sale or foreclosure (or the posting of notices
     preparatory to any sale or foreclosure) of any part of any asset to satisfy
     such Lien prior to a final determination of such action;

          (j) Liens for taxes not delinquent or being contested in good faith
     based on the advice of counsel that such contest is meritorious and by
     appropriate proceedings and for which reserves adequate under GAAP are
     being maintained; and

          (k) any extension, renewal or replacement (or successive extensions,
     renewals or replacements), in whole or in part, of any Lien referred to in
     the foregoing clauses (a) to (h) inclusive or of any Debt secured thereby,
     provided that the principal amount of Debt secured thereby shall not exceed
     --------                                                                   
     the principal amount of Debt so secured at the time of such extension,
     renewal or replacement, and that such extension, renewal or replacement
     Lien shall be limited to all or part of substantially the same property
     which secured the Lien extended, renewed or replaced (plus improvements on
     such property);

provided that the Borrower and any one or more Subsidiaries may issue, assume or
- --------                                                                        
guarantee Debt secured by Liens which would otherwise be subject to the
foregoing restrictions or grant any such Lien to secure any such Debt in an
aggregate principal amount which, together with the aggregate outstanding
principal amount of all Debt of the Borrower and the Subsidiaries which would
otherwise be subject to the foregoing restrictions (not including Debt permitted
to be secured under clauses (a) to (g) inclusive above) and the aggregate Value
of the Sale and Lease-Back Transactions (as such terms are defined in Section
5.03 hereof) in existence at such time (not including Sale and Lease-Back
Transactions as to which the Borrower has complied with Section 5.03(b) hereof)
does not at any one time exceed 15% of the consolidated total assets of the
Borrower and its Consolidated Subsidiaries.

     SECTION 5.03.  Limitation on Sale and Lease-Back.  Neither the Borrower nor
                    ---------------------------------                           
any Subsidiary will enter into any arrangement with any Person (other than the
Borrower or a Subsidiary), or to which any such Person is a party, providing for
the leasing to the Borrower or a Subsidiary for a period of more than three
years of any property which
has been or is to be sold or transferred by the Borrower or such Subsidiary to
such Person or to any Person (other than the Borrower or a Subsidiary), to which
funds have been or are to be advanced

                                      38
<PAGE>
 
by such Person on the security of the leased property (in this Section and in
Section 5.02 hereof called a "Sale and Lease-Back Transaction") unless either:

          (a) the Borrower or such Subsidiary would be entitled, pursuant to the
     provisions of Section 5.02 hereof, to incur Debt in a principal amount
     equal to or exceeding the Value of such Sale and Lease-Back Transaction,
     secured by a Lien on the property to be leased, without equally and ratably
     securing the Notes; or

          (b) the Borrower (and in any such case the Borrower covenants and
     agrees that it will do so) during or immediately after the expiration of
     four months after the effective date of such Sale and Lease-Back
     Transaction (whether made by the Borrower or a Subsidiary) applies to the
     voluntary retirement of Debt of the Borrower ranking at least pari passu
     with the Notes an amount equal to the Value of such Sale and Lease-Back
     Transaction, less the principal amount of such Debt of the Borrower
     voluntarily retired by the Borrower within such four-month period,
     excluding retirements of such Debt as a result of conversions or pursuant
     to mandatory sinking fund or repayment provisions or (other than in the
     case of commercial paper) by payment at maturity.

For purposes of Section 5.02 hereof and this Section, the term "Value" shall
mean, with respect to a Sale and Lease-Back Transaction, as of any particular
time, the amount equal to the greater of (i) the net proceeds of the sale or
transfer of the property leased pursuant to such Sale and Lease-Back Transaction
or (ii) the fair value in the opinion of the Board of Directors of the Borrower
of such property at the time of entering into such Sale and Lease-Back
Transaction, in either case divided first by the number of full years of the
term of the lease and then multiplied by the number of full years of such term
remaining at the time of determination, without regard to any renewal or
extension options contained in the lease.

     SECTION 5.04.  Consolidation, Merger, Disposition of Assets.  The Borrower
                    --------------------------------------------               
will not (i) consolidate or merge with or into any other Person or (ii) sell,
lease or otherwise transfer all or any substantial part of its assets (whether
in a single transaction or in a series of related transactions) to any other
Person; provided that the Borrower may merge with another Person if (A) the
        --------                                                           
Borrower is the corporation surviving such merger and (B) immediately after
giving effect to such merger, no Default shall have occurred and be continuing;
and provided further that the Borrower may consolidate or merge with or into the
    -------- -------                                                            
Parent if (A) the Parent theretofore expressly assumes the obligations of the
Borrower hereunder and under the Notes by an instrument satisfactory in form and
substance to the Required Banks and (B) immediately after giving effect to such
consolidation or merger and such assumption, no Default shall have occurred and
be continuing; and provided further that the Borrower may (A) sell its inventory
                   -------- -------                                             
in the ordinary course of business and (B) sell, lease or otherwise transfer
such of its assets (including all or any portion of the stock of any Subsidiary)
on an arms-length basis to an Internally-Funded Subsidiary.  The Borrower will
not permit any Subsidiary which constitutes a substantial part of its assets to
consolidate or merge with or into, or transfer all or substantially all of its
assets (whether in a single transaction or in a series of related transactions)
to, any Person other than the Borrower or a Wholly-Owned Consolidated
Subsidiary.

                                      39
<PAGE>
 
For purposes of this Section, "substantial part of its assets" means assets
(including Subsidiaries or other Persons and valued at the higher of book or
fair market value) (y) representing more than 25% of the consolidated assets of
the Borrower and its Subsidiaries as reflected in the then most recent
consolidated annual financial statements of the Borrower and its Subsidiaries
delivered pursuant to Section 5.01(a) or (z) responsible for more than 25% of
the consolidated net revenues or of the consolidated net income of the Borrower
and its Subsidiaries as reflected in the financial statements referred to in the
preceding clause (y).  Notwithstanding the foregoing, the Banks will not
unreasonably withhold their consent to any sale, lease or other transfer of
assets by the Borrower or any of its Subsidiaries.

     SECTION 5.05.  Minimum Consolidated Net Worth.  Consolidated Net Worth will
                    ------------------------------                              
at no time be less than $1,500,000,000.

     SECTION 5.06.  Transactions with Affiliates.  The Borrower will not, and
                    ----------------------------                             
will not permit any Subsidiary to, directly or indirectly, pay any funds to or
for the account of, make any investment (whether by acquisition of stock or
indebtedness, by loan, advance, transfer of property, Guarantee or other
agreement to pay, purchase or service, directly or indirectly, any Debt, or
otherwise) in, lease, sell, transfer or otherwise dispose of any assets,
tangible or intangible, to, or participate in, or effect any transaction in
connection with any joint enterprise or other joint arrangement with, any
Affiliate; provided, however, that the foregoing provisions of this Section
           --------  -------                                               
shall not prohibit (a) the Borrower from declaring or paying any lawful dividend
to, or repurchasing its common stock from, any Affiliate so long as, after
giving effect thereto, no Default shall have occurred and be continuing, (b) the
Borrower or any Subsidiary (1) from making sales to or purchases from or leasing
from any Affiliate and, in connection therewith, extending credit or making
payments, or (2) from making payments for services rendered by any Affiliate or
(3) from participating in, or effecting any transaction in connection with, any
joint enterprise or other joint arrangement with any Affiliate if such sales,
purchases or leases are made or such services are rendered or the Borrower or
such Subsidiary participates in the ordinary course of business of the Borrower
or such Subsidiary, as the case may be, and, in the aggregate during each fiscal
year of the Borrower, the terms and conditions of all such sales, purchases,
leases, rendered services and participations are not materially less favorable
to the similar transactions with Persons who are not Affiliates and (c) the
Borrower or any Subsidiary from making payments of principal, interest and
premium on any Debt of the Borrower or such Subsidiary held by an Affiliate if
the terms of such Debt are substantially as favorable to the Borrower or such

meaning of Regulation U.

     seeking liquidation, reorganization or other relief with respect to itself
     or its debts under any bankruptcy, insolvency or other similar law now or

     shall be commenced against the Borrower, any Material Subsidiary or any two
     or more Subsidiaries which, if combined, would constitute a Material

     or hereafter in effect;

          (h) Termination of Plan:  any member of the ERISA Group shall fail to
              -------------------                                              
     pay when due an amount or amounts aggregating in excess of $20,000,000

     within the meaning of Section 4219(c)(5) of ERISA, with respect to, one or
     more Multiemployer Plans which could cause one or more members of the ERISA
     Group to incur a current payment obligation in excess of $20,000,000; or

          (i) Judgment Default:  a final, non-appealable judgment or order
              ----------------

     the Borrower or any Subsidiary and such judgment or order shall continue
     unsatisfied for a period of 30 days;

                                      42

Borrower terminate the Commitments, and they shall thereupon terminate, and/or
(ii) if requested by Banks holding Notes evidencing at least 66-2/3% in
aggregate principal amount of the Loans, by notice to the Borrower declare the
full unpaid principal of and accrued interest on the Loans and the Notes and all
other amounts payable hereunder to be immediately due and payable, whereupon the

                                   THE AGENT

     SECTION 7.01.  Appointment and Authorization.  Each Bank irrevocably
                    -----------------------------                        
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under this Agreement and the Notes as are delegated to
the Agent by the terms hereof or thereof, together with all such powers as are
reasonably incidental thereto.  The Agent shall not have a fiduciary
relationship in respect of any Bank by reason of this Agreement.

     SECTION 7.02.  Agent and Affiliates.  The First National Bank of Chicago
                    --------------------                                     
shall have the same rights and powers under this Agreement and its Notes as any
other Bank and may exercise or refrain from exercising the same as though it
were not the Agent, and The First National Bank of Chicago and its Affiliates
may accept deposits from, lend money to, and generally engage in any kind of
business with the Borrower or any Subsidiary or any Affiliate as if it were not
the Agent hereunder.

     SECTION 7.03.  Action by Agent.  The obligations of the Agent hereunder are
                    ---------------                                             
only those expressly set forth herein.  Without limiting the generality of the
foregoing, the Agent shall not be required to take any action with respect to
any Default, except as expressly provided in Article VI.

     SECTION 7.04.  Employment and Reliance on Agents and Counsel.  The Agent
                    ---------------------------------------------            
may execute any of its duties as Agent hereunder by or through employees,
agents, and attorneys-in-fact and shall not be answerable to the Banks, except
as to money or securities received by it or its authorized

                                      43
<PAGE>
 
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.  In addition, the Agent may consult with
legal counsel (who may be employees of the Agent or counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

     SECTION 7.05.  Liability of Agent.  Neither the Agent, the Arranger, nor
                    ------------------                                       
any of their respective directors, officers, agents or employees shall be liable
for any action taken or not taken by it in connection herewith (i) with the
consent or at the request of the Required Banks or (ii) in the absence of its
own gross negligence or willful misconduct.  Neither the Agent, the Arranger,
nor any of their respective directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into or verify (i) any
statement, warranty or representation made in connection with this Agreement or
any Borrowing hereunder; (ii) the performance or observance of any of the
covenants or agreements of the Borrower; (iii) the satisfaction of any condition
specified in Article III, except receipt of items required to be delivered to
the Agent; or (iv) the validity, effectiveness or genuineness of this Agreement,
the Notes or any other instrument or writing furnished in connection herewith.
Neither the Agent nor the Arranger shall incur any liability by acting in
reliance upon any Note, notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex, facsimile transmission or similar
writing) believed by it in good faith to be genuine or to be signed by the
proper party or parties.

     SECTION 7.06.  Reimbursement and Indemnification.  The Banks agree to
                    ---------------------------------                     
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (i) for any amounts not reimbursed by the Borrower for which the
Agent (for clarity, in its capacity as Agent, not as a Bank) is entitled to
reimbursement by the Borrower under this Agreement, (ii) for any other expenses
incurred by the Agent on behalf of the Banks, in connection with the
administration and enforcement of this Agreement and the Notes and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in any way relating to or
arising out of this Agreement, the Notes or any other document delivered in
connection herewith or the transactions contemplated hereby, or the enforcement
of any of the terms hereof or of any such other documents, provided that no Bank
shall be liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Agent.

     SECTION 7.07.  Credit Decision.  Each Bank acknowledges that it has,
                    ---------------                                      
independently and without reliance upon the Agent, the Arranger or any other
Bank, and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon the Agent,
the Arranger or any other Bank, and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking any action under this Agreement.

     SECTION 7.08.  Successor Agent.  The Agent may resign at any time by giving
                    ---------------                                             
written notice thereto to the Banks and the Borrower.  Upon any such
resignation, the Required Banks shall have the right to appoint a successor
Agent who has been approved by the Borrower (such approval not to be
unreasonably withheld or delayed).  If no successor Agent shall have been so
appointed by the Required Banks, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving notice of resignation, then the
retiring Agent may, on behalf of the Banks, appoint a successor Agent.  The
successor Agent shall be (i) a commercial bank organized under the laws of the
United States of America or of any state thereof and having a combined capital
and surplus of at least $100,000,000 and (ii) a Bank, unless the Borrower
consents to the successor Agent not being a Bank, which consent may not be
unreasonably withheld or delayed.  Upon the acceptance by a successor Agent of
its appointment as Agent hereunder, it shall thereupon succeed to and become
vested with all the rights and duties of the retiring Agent and the retiring
Agent shall be discharged from its duties and obligations hereunder.  Each
successor Agent shall notify promptly the Borrower of its appointment as Agent
hereunder.  After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent.

     SECTION 7.09.  Co-Agents.  None of the Banks identified on the signature
                    ---------                                                
pages of this Agreement as a "Co-Agent" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement other than those
applicable to all Banks as such.  Without limiting the foregoing, none of the
Banks so identified as a "Co-Agent" shall have or be deemed to have any
fiduciary relationship with any Bank.  Each Bank acknowledges that it has not
relied, and will not rely, on any of the Banks identified as Co-Agents in
deciding to enter into this Agreement or in taking or not taking action
hereunder.

                            CHANGE IN CIRCUMSTANCES

     SECTION 8.01.  Basis for Determining Interest Rate Inadequate or Unfair.
                    --------------------------------------------------------  
(a) If on or prior to the first day of any Interest Period for any Fixed Rate
Borrowing (other than a Money Market Rate Loan):

          (1)  the Agent is advised by the Reference Banks that deposits in the
     applicable currency (in the applicable amounts) are not being offered to
     the Reference Banks in the relevant market for such Interest Period, or

          (2)  the Required Banks advise the Agent that the London Interbank
     Offered Rate as determined by the Agent will not adequately and fairly
     reflect the cost to such Banks of funding their Euro-Currency Loans or
     Money Market LIBOR Loans, as the case may be, for such Interest Period,

                                      45
<PAGE>
 
the Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon until the Agent notifies the Borrower that the circumstances giving
rise to such notice no longer exist: (A) the New York Interbank Offered Rate
shall replace the London Interbank Offered Rate for purposes of interest rate
determinations hereunder for Euro-Currency Borrowings and Money Market LIBOR
Borrowings for such Interest Period (and all references herein to the London
interbank market and the London Interbank Offered Rate for such purposes shall,
unless the context otherwise requires, be deemed to be references to the New
York interbank market and the New York Interbank Offered Rate, respectively), as
the case may be, and (B) unless the Borrower notifies the Agent at least one
Domestic Business Day before the date of any Fixed Rate Borrowing for which a
Notice of Borrowing has previously been given that it elects not to borrow on
such date or that it elects to borrow in another currency such that clause (1)
or (2) above is not applicable thereto,

          (i)  if such Fixed Rate Borrowing is a Euro-Currency Borrowing, the
     interest rate for such Euro-Currency Borrowing shall be determined on the
     basis of the New York Interbank Offered Rate if all of the procedures set
     forth herein for a Euro-Currency Borrowing on such basis (including the
     required notice to the Banks) can be complied with at such time or, if
     clause (1) or (2) of this subsection is applicable to the New York
     Interbank Offered Rate at such time, such Euro-Currency Borrowing shall
     instead be made as a Base Rate Borrowing; provided that, if such Euro-
                                               --------                   
     Currency Borrowing was to be denominated in a currency other than Dollars,
     the principal amount of the Base Rate Borrowing shall be the Dollar Amount
     of the principal amount of such Euro-Currency Borrowing, and

          (ii) if such Fixed Rate Borrowing is a Money Market LIBOR Borrowing,
     the interest rate for such Money Market LIBOR Borrowing shall be determined
     on the basis of the New York Interbank Offered Rate if all of the
     procedures set forth herein for a Money Market LIBOR Borrowing on such
     basis (including the required notice to the Banks) can be complied with at
     such time or, if clause (1) or (2) of this subsection is applicable to the
     New York Interbank Offered Rate at such time, the Money Market LIBOR Loans
     comprising such Borrowing shall be made in Dollars in a principal amount
     equal to the Dollar Amount of the principal amount of such Money Market
     LIBOR Borrowing and shall bear interest for each day from and including the
     first day to but excluding the last day of the Interest Period applicable
     thereto at the Base Rate for such day.

     (b) If clause (1) or (2) of subsection (a) of this Section becomes
applicable when the New York Interbank Offered Rate has replaced the London
Interbank Offered Rate hereunder, then the Agent shall give notice to the
Borrower of such condition and the Borrower and the Agent (in consultation with
the Banks) shall promptly enter into negotiations in good faith with a view to
agreeing upon an alternative basis (a "Substitute Basis") acceptable to the
Borrower and the Banks for determining the interest rate which shall be
applicable to the affected Euro-Currency Borrowings or Money Market LIBOR
Borrowings, which rate shall reflect the cost to the Banks of maintaining such
Euro-Currency Borrowings plus the applicable Syndicated Margin or maintaining
such Money Market LIBOR Loans plus any applicable Money Market Margin, as the
case may be.  If, prior to the expiration of 20 days from the date of such
notice by the Agent, the Borrower and the Banks shall

                                      46
<PAGE>
 
agree upon a Substitute Basis, interest on such Euro-Currency Borrowings or
Money Market LIBOR Borrowings for the affected Interest Periods commencing
during the period beginning two Euro-Currency Business Days after the date of
such notice and ending on the date three Euro-Currency Business Days after the
Agent notifies the Borrower and the Banks that the condition specified in clause
(1) or (2) of subsection (a) of this Section has ceased to be in effect shall be
determined on such Substitute Basis.  If no such agreement has been reached by
the expiration of such 20-day period, the Agent shall so notify the Banks and
each Bank shall, within ten days after the date of such notice, notify the
Borrower (through the Agent) of the rate (or the basis of determining the rate)
at which it is prepared to maintain such Euro-Currency Borrowings or Money
Market LIBOR Borrowings held by it hereunder for the affected Interest Periods
(which rate shall reflect the cost to such Bank of maintaining such Borrowings
plus the applicable Syndicated Margin or plus any applicable positive Money
Market Margin, as the case may be) and such rate (or basis) shall be applicable
to such Euro-Currency Borrowings or Money Market LIBOR Borrowings, as the case
may be, held by it for the affected Interest Periods applicable thereto referred
to in the preceding sentence.  The Agent shall determine the total amount of
interest payable by the Borrower on each date for the payment of interest
hereunder determined in accordance with this subsection (b) (to the extent it
has received the necessary information from the Banks) and notify the Borrower
of such total amount (provided that no Bank's right to receive any interest
payable to it hereunder shall be impaired by its failure to provide such
information to the Agent).  The Borrower shall have the right at any time to
suspend the obligation of each Bank notifying a rate (or basis) pursuant to the
second preceding sentence of this subsection to make Euro-Currency Loans.

     SECTION 8.02.  Illegality.  If, after July 23, 1997, the adoption of any
                    ----------                                               
applicable law, rule or regulation, or any change therein, or any change 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 Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for any Bank (or its Applicable Lending Office) to make, maintain or
fund its Euro-Currency Loans and such Bank shall so notify the Agent, the Agent
shall forthwith give notice thereof to the other Banks and the Borrower,
whereupon until such Bank notifies the Borrower and the Agent that the
circumstances giving rise to such suspension no longer exist, the obligation of
such Bank to make Euro-Currency Loans shall be suspended. Before giving any
notice to the Agent pursuant to this Section, such Bank shall designate a
different Applicable Lending Office if such designation will avoid the need for
giving such notice and will not, in the judgment of such Bank, be otherwise
materially disadvantageous to such Bank.  If such Bank shall determine that it
may not lawfully continue to maintain and fund any of its outstanding Euro-
Currency Loans to maturity and shall so specify in such notice, the Borrower
shall immediately prepay in full the then outstanding principal amount of each
such affected Euro-Currency Loan, together with accrued interest thereon.
Concurrently with prepaying each such affected Euro-Currency Loan, the Borrower
shall borrow a Base Rate Loan (or, subject to Section 2.03 and the willingness
of such Bank in its own discretion to submit a Money Market Quote, a Money
Market Rate Loan) from such Bank in a principal amount equal to the Dollar
Amount of the principal amount of such affected Euro-Currency Loan for an
Interest Period coincident with the

                                      47
<PAGE>
 
remaining term of the Interest Period applicable to such affected Euro-Currency
Loan, and such Bank shall make such a Base Rate Loan.

     SECTION 8.03.  Increased Cost and Reduced Return.  (a) If on or after (x)
                    ---------------------------------                         
July 23, 1997, in the case of any Syndicated Loan or any obligation to make
Syndicated Loans or (y) the date of the related Money Market Quote, in the case
of any Money Market Loan, the adoption of any applicable law, rule or
regulation, or any change therein, or any change 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 Bank (or its Applicable Lending Office) with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency:

          (i)  shall subject any Bank (or its Applicable Lending Office) to any
     tax, duty or other charge with respect to its Fixed Rate Loans, its Notes
     or its obligation to make Euro-Currency Loans, or shall change the basis of
     taxation of payments to any Bank (or its Applicable Lending Office) of the
     principal of or interest on its Fixed Rate Loans or any other amounts due
     under this Agreement in respect of its Fixed Rate Loans or its obligation
     to make Euro-Currency Loans (except for changes in the rate of tax on the
     overall net income of such Bank or its Applicable Lending Office imposed by
     the jurisdiction in which such Bank's principal executive office or
     Applicable Lending Office is located) or

          (ii) shall impose, modify or deem applicable any reserve, special
     deposit, deposit insurance assessment or similar requirement (including,
     without limitation, any such requirement imposed by the Board of Governors
     of the Federal Reserve System, but excluding with respect to any Euro-
     Currency Loan or Money Market LIBOR Loan any such requirement included in
     an applicable Euro-Currency Reserve Percentage) against assets of, deposits
     with or for the account of, or credit extended by, any Bank (or its
     Applicable Lending Office) or shall impose on any Bank (or its Applicable
     Lending Office) or on the London interbank market any other condition
     affecting its Fixed Rate Loans, its Notes or its obligation to make Euro-
     Currency Loans,

and the result of any of the foregoing is to increase the cost to such Bank (or
its Applicable Lending Office) of making or maintaining any Fixed Rate Loan, or
to reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under its Notes with respect
thereto, by an amount deemed by such Bank to be material, then, within 15 days
after demand by such Bank (with a copy to the Agent), the Borrower shall pay to
such Bank (without duplication of amounts otherwise payable hereunder) such
additional amount or amounts as will compensate such Bank for such increased
cost or reduction with respect to such affected Fixed Rate Loan or such affected
sum.

     (b) If any Bank shall have reasonably determined that, after July 23, 1997,
the adoption of any applicable law, rule or regulation regarding capital
adequacy or any change therein, or any change 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 Bank (or its Applicable Lending Office) with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency,

                                      48
<PAGE>
 
has or has had the effect of reducing the rate of return on the capital of such
Bank (or its parent) as a consequence of its obligations hereunder to a level
below that which such Bank (or its parent) could have achieved but for such
adoption, change or compliance (taking into consideration such Bank's policies
with respect to capital adequacy) by an amount deemed by such Bank to be
material, then from time to time, within 15 days after demand by such Bank (with
a copy to the Agent), the Borrower shall pay to such Bank (without duplication
of amounts otherwise payable hereunder) such additional amount or amounts as
will compensate such Bank (or its parent) for such reduction.

     (c) Each Bank will promptly notify the Borrower and the Agent of any event
of which it has knowledge, occurring after July 23, 1997, which will entitle
such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise materially disadvantageous to such Bank.  A certificate of
any Bank claiming compensation under this Section, setting forth the additional
amount or amounts to be paid to it hereunder and setting forth in reasonable
detail a reasonable basis therefor, shall be conclusive in the absence of
manifest error.  In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

     (d) Notwithstanding any other provision of this Agreement, the Borrower
shall have no obligation to make any payment under this Section 8.03 to the
extent that such payment would not have been required (i) if such Bank's
representation and warranty in Section 2.16(f) had been accurate, or (ii) if
such Bank had complied with its obligations under Section 2.16(g).

     SECTION 8.04.  Substitute Loans.  If (i) the obligation of any Bank to make
                    ----------------                                            
Euro-Currency Loans has been suspended pursuant to Section 8.01(b) or 8.02 or
(ii) any Bank has demanded compensation under Section 8.03(a) and the Borrower
shall, by at least five Euro-Currency Business Days' prior notice to such Bank
through the Agent, have elected that the provisions of this Section shall apply
to such Bank, then, unless and until such Bank notifies the Borrower that the
circumstances giving rise to such suspension or demand for compensation no
longer apply:

          (a) all Loans denominated in Dollars which would otherwise be made by
     such Bank as Euro-Currency Loans shall be made instead as Base Rate Loans,

          (b) all Loans denominated in a currency other than Dollars which would
     otherwise be made by such Bank as Euro-Currency Loans shall be made instead
     as Base Rate Loans in Dollars in a principal amount equal to the Dollar
     Amount of the principal amount of such Euro-Currency Loans, and

          (c) after each of its Euro-Currency Loans has been repaid, all
     payments of principal which would otherwise be applied to repay such Fixed
     Rate Loans shall instead be applied to repay its Loans made pursuant to
     Section 8.02 or clauses (a) or (b) above.

     SECTION 8.05.  Certain Reserve Compensation.  Each Bank may require the
                    ----------------------------                            
Borrower to pay, contemporaneously with each payment of interest on the Euro-
Currency Borrowings of the Borrower, additional interest on the related Euro-
Currency Loan of such Bank at a rate per annum equal to the excess of (i)(A) the
applicable London Interbank Offered Rate divided by (B) one minus the Euro-
Currency Reserve Percentage over (ii) the rate specified in clause (i)(A).  In
addition, each

                                      49
<PAGE>
 
Bank may require the Borrower to pay, contemporaneously with each payment of
interest on the Euro-Currency Borrowings of the Borrower which are denominated
in pounds sterling, additional interest on the related Euro-Currency Loan of
such Bank at the percentage calculated from time to time by such Bank to be the
percentage required to fully compensate such Bank for all reserve costs,
liabilities, expenses and assessments which have been incurred by such Bank (or
its Applicable Lending Office) in complying with any and all requirements of any
relevant United Kingdom banking authority or authorities applicable to such Bank
(or its Applicable Lending Office) regarding the making, funding or maintaining
of such Euro-Currency Loan  (including, without limitation, any and all liquid
asset maintenance requirements of the Bank of England).  A certificate of any
Bank claiming compensation under the preceding sentence, setting forth the
additional interest to be paid to it thereunder and setting forth in reasonable
detail a reasonable basis therefor, shall be conclusive in the absence of
manifest error, and in determining the amount of such interest, such Bank may
use any reasonable averaging and attribution methods.

     Any Bank wishing to require payment of such additional interest (x) shall
so notify the Borrower and the Agent, in which case such additional interest on
the Euro-Currency Loans of such Bank shall be payable in the currency of such
Loan to such Bank at the place indicated in such notice with respect to each
Interest Period commencing at least five Euro-Currency Business Days after the
giving of such notice and (y) shall notify the Borrower at least five Euro-
Currency Business Days prior to each date on which interest is payable on such
Euro-Currency Loans of the amount (and currency thereof) then due it under this
Section.

     SECTION 8.06.  Substitution of Bank.  If (i) the obligation of any Bank to
                    --------------------                                       
make Euro-Currency Loans has been suspended pursuant to either Section 8.01(b)
or Section 8.02 of either this Agreement or the Other Agreement or (ii) any Bank
has demanded compensation under any of Sections 2.16, 8.03 or 8.05 of either
this Agreement or the Other Agreement, the Borrower shall have the right, with
the assistance of the Agent, to seek a mutually satisfactory substitute bank or
banks (which may be one or more of the Banks) to purchase and assume all of the
rights and obligations of such Bank under this Agreement, the Other Agreement
and such Bank's "Notes" (as defined in both this Agreement and the Other
Agreement), all in accordance with the provisions of Section 9.07(c) of this
Agreement and Section 9.07(c) of the Other Agreement and subject to such Bank
receiving payment in full of all amounts owing to it under this Agreement, the
Other Agreement, and its "Notes" (as defined in both this Agreement and the
Other Agreement).

     SECTION 9.05.  Amendments, Etc.  Any provision of this Agreement or the
                    ---------------                                         
Notes may be amended or waived if, but only if, such amendment or waiver is in
writing and is signed by the Borrower and the Required Banks (and, if the rights
or duties of the Agent are affected thereby, by the Agent); provided that the
                                                            --------

     SECTION 9.06.  Counterparts; Effectiveness; Termination of Existing Credit

which taken together shall constitute one and the same instrument, and any of
the parties hereto may execute this Agreement by signing any such counterpart.
This Agreement shall become effective when (a) the Agent shall have received
counterparts hereof signed by the Borrower, each Bank listed on the signature
pages hereof and the Agent, and (b) all of the Borrower's obligations under the
Existing Credit Agreement shall have been satisfied (except for any obligations
under Article VIII, Section 2.16 and Section 9.04 therein).  Each Bank that is a
party to the Existing Credit Agreement acknowledges and agrees that,
notwithstanding anything to the contrary therein, upon the effectiveness of this
Agreement, the commitments of the banks under the Existing Credit Agreement to
make loans thereunder shall be automatically terminated and any notice
requirements in respect of such termination or in respect of any prepayment of
loans thereunder shall be waived.  The Agent shall notify the Borrower and the
Banks of the effectiveness of this Agreement by delivery of a notice in the form
of Exhibit H hereto.

     SECTION 9.07.  Successors and Assigns.  (a)  The provisions of this
                    ----------------------                              
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks and the Agent.

     (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans.  In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement.  Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrower hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
                                                                      --------
that such participation agreement may provide that such Bank will not agree to
any modification, amendment or waiver of this Agreement described in clause (ii)

                                      52
<PAGE>
 
or (iii) of Section 9.05 without the consent of the Participant.  The Borrower
agrees that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Sections 2.13, 2.15, 2.16, 9.04 and
Article VIII to the extent of its participating interest and with such benefits
to be determined as if the related Bank had not granted such participation.  An
assignment or other transfer which is not permitted by subsection (c) or (d)
below shall be given effect for purposes of this Agreement only to the extent of
a participating interest granted in accordance with this subsection (b).

     (c) With (and subject to) the written consent of the Borrower and the Agent
(such consents not to be unreasonably withheld and, in the case of an assignment
to an Affiliate, not to be required), any Bank may at any time assign to one or
more banks or other institutions (each an "Assignee") all, or a proportionate
part of all, of its rights and obligations under this Agreement and the Notes,
and such Assignee shall assume such rights and obligations, pursuant to an
Assignment and Assumption Agreement in substantially the form of Exhibit G
hereto executed by such Assignee and such transferor Bank; provided, that
simultaneously with each such assignment, the transferor Bank shall assign to
the same Assignee the same proportionate share of all of its rights and
obligations, if any, under the Other Agreement in accordance with the provisions
of Section 9.07(c) of the Other Agreement.  Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required.  Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Agent and the Borrower
shall make appropriate arrangements so that, if required, new Notes are issued
to the Assignee.  In connection with any such assignment under this Agreement,
the transferor Bank shall pay to the Agent an administrative fee for processing
such assignment equal to $1,500.

     (d) Any Bank may at any time assign all or any portion of its rights under
this Agreement and its Notes to a Federal Reserve Bank (without any requirement
to obtain the consent of the Borrower or the Agent thereto).  No such assignment
shall release the transferor Bank from its obligations hereunder.

     (e) No Assignee, Participant or other transferee of any Bank's rights shall
be entitled to receive any greater payment under Section 8.03 or 8.05 than such
Bank would have been entitled to receive with respect to the rights transferred,
unless such transfer is (i) made with the Borrower's prior written consent or
(ii) made to either (y) a Bank already party to this Agreement at the time of
such assignment or (z) an affiliate of the transferor Bank.

     (f) If any Reference Bank assigns all of its rights and obligations under
this Agreement and its Notes to an unaffiliated institution, the Agent shall, in
consultation with the Borrower and with the consent of the Required Banks,
appoint another Bank to act as a Reference Bank hereunder.

     SECTION 9.08.  Survival.  The obligations of the Borrower under Article
                    --------                                                
VIII and Sections 2.16 and 9.04 shall survive the repayment of the Loans and the
termination of the Commitments.

                                      53
<PAGE>
 
     SECTION 9.09.  Acknowledgement.  The Borrower acknowledges that the Banks
                    ---------------                                           
have entered into this Agreement in reliance on the Borrower's assurance that it
does not intend to use the proceeds of any Borrowings hereunder in a manner
which would violate any applicable law or governmental rule or regulation.

     SECTION 9.10.  Headings.  The Table of Contents and Article and Section
                    --------                                                
headings used herein shall not affect the interpretation of any provision of
this Agreement.

     SECTION 9.11.  Sharing of Setoffs.  Each Bank agrees that, if it shall, by
                    ------------------                                         
exercising any right of setoff or counterclaim or otherwise, receive payment of
a proportion of the aggregate amount of principal and interest due with respect
to any Note held by it which is greater than the proportion received by any
other Bank in respect of the aggregate amount of principal and interest due with
respect to any Note held by such other Bank (other than disproportionate
payments to any Bank provided for by this Agreement), the Bank receiving such
proportionately greater payment shall purchase such participations in the Notes
held by the other Banks, and such other adjustments shall be made, as may be
required so that all such payments of principal and interest with respect to the
Notes held by the Banks shall be shared by the Banks pro rata; provided that
                                                               --------     
nothing in this Section shall impair the right of any Bank to exercise any right
of setoff or counterclaim it may have and to apply the amount recovered thereby
to the payment of indebtedness of the Borrower other than its indebtedness under
the Notes.  If under any applicable bankruptcy, insolvency or other similar law,
any Bank receives a secured claim in lieu of a setoff to which this Section
applies, such Bank shall, to the extent practicable, exercise its rights in
respect of such secured claim in a manner consistent with the rights of the
Banks entitled under this Section to share in the benefits of any recovery on
such secured claim.  The Borrower agrees, to the fullest extent it may
effectively do so under applicable law, that any holder of a participation in a
Note, whether or not acquired pursuant to the foregoing arrangements, may
exercise rights of setoff or counterclaim and other rights with respect to such
participation as fully as if such holder of a participation were a direct
creditor of the Borrower in the amount of such participation.

     SECTION 9.12.  Collateral.  Each of the Banks represents to the Agent and
                    ----------                                                
each of the other Banks that it in good faith is not relying upon any "margin
stock" (as defined in Regulation U) as collateral in the extension or

     SECTION 9.13.  Consent to Jurisdiction.  (a)  The Borrower irrevocably
                    -----------------------                                
submits to the jurisdiction of any federal or Illinois state court sitting in
Chicago, Illinois over any suit, action or proceeding arising out of or relating
to this Agreement or any Note.  The Borrower irrevocably waives, to the fullest
extent permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in such court
and any claim that any suit, action or proceeding brought in such court has been
brought in an inconvenient forum. The Borrower agrees that a final judgment in
any such suit, action or proceeding brought in such a court shall be conclusive
and binding upon the Borrower and may be enforced in any federal or Illinois
state court sitting in Chicago, Illinois (or any other courts to the
jurisdiction of which the Borrower is or may be subject) by a suit upon such
judgment, provided that service of process is effected upon the Borrower in one
of the manners specified in subsection (b) of this Section or as otherwise
permitted by law.

subsection (a) of this Section in any federal or Illinois state court sitting in
Chicago, Illinois by mailing a copy thereof by registered or certified air mail,
postage prepaid, return receipt requested, to the Borrower at its address
specified in Section 9.01 or to any other address of which the Borrower shall
have given written notice to the Agent.  The Borrower irrevocably waives, to the
fullest extent permitted by law, all claim of error by reason of any such
service in any such suit, action or proceeding brought by the Agent or any Bank.
The Borrower agrees that such service shall be deemed in every respect effective
service of process upon the Borrower in any such suit, action or proceeding and
shall, to the fullest extent permitted by law, be taken and held to be valid and
personal service upon and personal delivery to the Borrower.

     (c) No Limitation on Service or Suit.  Nothing in this Article shall affect

permitted by law or limit the right of the Agent or any Bank to bring

which the Borrower has any assets.

To the Banks and the Agent
 Referred to Below
c/o The First National Bank
 of Chicago, as Agent
One First National Plaza
Chicago, Illinois 60670

Ladies and Gentlemen:

     I am [General Counsel] [Associate General Counsel-Corporate] of ARCO
Chemical Company (the "Borrower") and as such have acted as counsel, or
supervised attorneys who have acted as counsel, for the Borrower in connection
with Credit Agreement B, dated as of July 23, 1997 (the "Credit Agreement"),
among ARCO Chemical Company, the banks listed on the signature pages thereof,
and The First National Bank of Chicago, as Agent. Capitalized terms used but not
otherwise defined herein have the meanings assigned to such terms in the Credit
Agreement.

     I have examined originals or copies, certified or otherwise identified to
my satisfaction, of such documents, corporate records, certificates of public
officials and other instruments and have conducted such other investigations of
fact and law as I have deemed necessary or advisable for purposes of this
opinion.

     Upon the basis of the foregoing, I am of the opinion that:

     1.  (a)  The Borrower (i) is a corporation duly incorporated, validly
existing and in good standing under the laws of Delaware and (ii) either is
qualified to do business and in good standing in each jurisdiction where the
ownership of its properties or the conduct of its business requires such
qualification or is subject to no material liability or disability by reason of
the failure to be so qualified in any such jurisdiction.

     (b)  The Borrower has all corporate powers and authority, governmental
permits, licenses, consents, authorizations, orders and approvals and other
authorizations as are necessary to carry on its business substantially as
presently conducted except for such of the foregoing the absence of which would
not, in the aggregate, subject the Borrower to any material liability or
disability.
<PAGE>
 
     (c)  The execution, delivery and performance by the Borrower of the Credit
Agreement and the Notes, and Borrowings under the Credit Agreement by the
Borrower, are within the corporate power and authority of the Borrower and have
been duly authorized by all necessary corporate proceedings by the Borrower.

     (d)  Neither such authorization nor the execution, delivery and performance
by the Borrower of the Credit Agreement or of the Notes, nor any Borrowing by
the Borrower when made, will conflict with, result in a breach of or constitute
a default under any of the terms, conditions or provisions of any law or any
regulation, order, writ, injunction or decree of any court or governmental
authority or of the Certificate of Incorporation or By-Laws of the Borrower or
result in the violation or contravention of, or the acceleration of any
obligation under, or cause the creation of any Lien on any of the properties of
the Borrower pursuant to the provisions of, any indenture, agreement or other
instrument to which it is a party or by which it is bound.

     (e)  Assuming its due execution by the Banks and the Agent, the Credit
Agreement constitutes a legal, valid and binding agreement of the Borrower and
the Notes, when duly executed on behalf of the Borrower and delivered in
accordance with the Credit Agreement, will constitute legal, valid and binding
obligations of the Borrower enforceable in accordance with their respective
terms (subject, as to enforcement of remedies, to applicable bankruptcy,
reorganization, insolvency, moratorium or other laws affecting creditors' rights
generally from time to time in effect and to general principles of equity).

     2.  Except as previously disclosed in writing to the Banks prior to July
23, 1997, there is no action, suit or proceeding pending or, to my knowledge,
threatened against or affecting the Borrower or any of its subsidiaries in any
court or before or by any arbitrator, governmental department, agency or
instrumentality (i) which is likely to have a material adverse effect upon the
Borrower's ability to pay and perform its obligations under the Bank Credit
Documents in accordance with their respective terms or (ii) which in any manner
draws into question the validity of any of the Bank Credit Documents.  In this
regard, the Borrower has brought to your attention the Borrower's annual report
on Form 10-K for the year ended December 31, 1996, and the Borrower's quarterly
report on Form 10-Q for the three months ended March 31, 1997.

     3.  No consent, authorization, order or approval of (or filing or
registration with) any governmental commission, board or other regulatory
authority (other than routine reporting requirements) is required for the
execution, delivery and performance by the Borrower of the Credit Agreement or
the Notes or for Borrowings under the Credit Agreement.

     4.  The Borrower is not an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

     5.  The Cross-Indemnification Agreement, as amended to the date hereof, and
the Tax Sharing Agreement are in full force and effect in accordance with their
respective terms.

     6.  Each of the Borrower's Subsidiaries that is a corporation is duly
incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has all corporate powers and all governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted except for licenses, authorizations, consents or
approvals the absence of which will not materially and adversely affect the
business of the Borrower and its Consolidated Subsidiaries taken as a whole.

     I am counsel admitted to practice in the Commonwealth of Pennsylvania.  In
giving the foregoing opinion, I express no opinion as to the effect (if any) of
any laws of any jurisdiction other than the general corporate laws of the State
of Delaware and the laws of the Commonwealth of Pennsylvania.  I have assumed
for the purposes of this opinion that the applicable laws of the State of
Illinois are the same as the laws of the Commonwealth of Pennsylvania.

                       Very truly yours,

                                  WITNESSETH

     WHEREAS, this Assignment and Assumption Agreement (the "Agreement") relates
to Credit Agreement B dated as of July 23, 1997 among the Company, the Assignor
and the other Banks party thereto, as Banks, and the Agent (the "Credit
Agreement");

     WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans in an aggregate principal amount at any time
outstanding not to exceed $_______________;

     WHEREAS, Syndicated Loans made by the Assignor under the Credit Agreement
in the aggregate principal amount of $__________ are outstanding at the date
hereof; and

     WHEREAS, the Assignor proposes to assign to the Assignee all of the rights
of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $___________ (the "Assigned
Amount"), together with a corresponding portion of its outstanding Syndicated
Loans, and the Assignee proposes to accept assignment of such rights and assume
the corresponding obligations from the Assignor on such terms;

     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
contained herein, the parties hereto agree as follows:

     SECTION 1.  Definitions.  All capitalized terms not otherwise defined
                 -----------

     SECTION 2.  Assignment.  The Assignor hereby assigns and sells to the

Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount, and the Assignee hereby accepts such assignment
from the Assignor and assumes all of the obligations of the Assignor under the
Credit Agreement to the extent of the Assigned Amount, including the purchase
from the Assignor of the corresponding portion of the principal amount of the
Syndicated Loans made by the Assignor outstanding at the date hereof.  Upon the
execution and delivery hereof by the Assignor, the Assignee, the Company and the
Agent and the payment of the amounts specified in Section 3 required to be paid
on the date hereof (i) the Assignee shall,
<PAGE>
 
as of the date hereof, succeed to the rights and be obligated to perform the
obligations of a Bank under the Credit Agreement with a Commitment in an amount
equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as
of the date hereof, be reduced by a like amount and the Assignor released from
its obligations under the Credit Agreement to the extent such obligations have
been assumed by the Assignee. The assignment provided for herein shall be
without recourse to the Assignor.

     SECTION 3.  Payments.  As consideration for the assignment and sale
                 --------                                               
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds an amount equal to $__________*.  It is understood
that facility fees with respect to the Assigned Amount accrued to the date
hereof are for the account of the Assignor and such fees accruing from and
including the date hereof are for the account of the Assignee.  Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under the
Credit Agreement which is for the account of the other party hereto, it shall
receive the same for the account of such other party to the extent of such other
party's interest therein and shall promptly pay the same to such other party.

     SECTION 4.  Consent of the Company and the Agent.  This Agreement is
                 ------------------------------------                    
conditioned upon the consent of the Company and the Agent pursuant to Section
9.07(c) of the Credit Agreement.  The execution of this Agreement by the Company
and the Agent is evidence of this consent.  Pursuant to Section 9.07(c) the
Company agrees to execute and deliver a Note payable to the order of the
Assignee to evidence the assignment and assumption provided for herein.**



_________________________
*     Amount should combine principal together with accrued interest and
      breakage compensation, if any, to be paid by the Assignee, net of any
      portion of any upfront fee to be paid by the Assignor to the Assignee. It
      may be preferable in an appropriate case to specify these amounts
      generically or by formula rather than as a fixed sum .

**    Delete this Section 4 if no consent is required pursuant to Section
      9.07(c) of the Credit Agreement.

                 ------------------------                                       
or warranty in connection with, and shall have no responsibility with respect
to, the solvency, financial condition, or statements of the Borrower, or the
validity and enforceability of the obligations of the Borrower in respect of the
Credit Agreement or any Note.  The Assignee acknowledges that it has,
independently and without reliance on the Assignor, and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and will continue to be responsible for
making its own independent appraisal of the business, affairs and financial

written.

The First National Bank of Chicago, as
 Agent, and the other financial institutions
 which are parties to each of the Credit
 Agreements referred to below

   Re: ARCO Chemical Company
       ---------------------

Ladies and Gentlemen:

   We have acted as special counsel to The First National Bank of Chicago, as
Agent (in such capacity, the "Agent"), in connection with Credit Agreement A and
Credit Agreement B (collectively, the "Credit Agreements"), each dated as of
July 23, 1997, among ARCO Chemical Company (the "Borrower"), various financial
institutions, and the Agent.  Capitalized terms used herein and not otherwise
defined shall have the meanings attributed to them in each of the Credit
Agreements.

   In connection herewith, we have examined counterparts of each Credit
Agreement executed by the Borrower, each of the Banks and the Agent; and each
Note issued by the Borrower on the date hereof pursuant to the Credit Agreements
(the "Notes").  In connection with such examination, we have assumed the
genuineness of all signatures, the authority of the persons signing such
documents and the authenticity of such documents.  We also have assumed, without
any independent investigation, that (a) each Credit Agreement and each Note has
been duly authorized, executed and delivered by each of the parties thereto and
(b) each Credit Agreement is the legal, valid and binding obligation of each
party thereto other than the Borrower, enforceable against each such party in
accordance with its terms.

   Based upon the foregoing, and subject to the qualifications set forth below,
we are of the opinion that, under the laws of the State of Illinois:
 
   (1) Each Credit Agreement is the legal, valid and binding obligation of the
       Borrower, enforceable against the Borrower in accordance with its terms.

   (2) The Notes are the legal, valid and binding obligations of the Borrower,
       enforceable against the Borrower in accordance with their terms.
<PAGE>
 
______, 1997
Page 2

   Our opinions are subject to the following qualifications:

   (a) Our opinions are subject to the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or similar law
affecting creditors' rights generally and to the effect of general principles of
equity (regardless of whether considered in a proceeding in equity or at law),
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing.

   (b) We express no opinion as to indemnification or contribution obligations
which contravene public policy.

   (c) We express no opinion as to any provision of either Credit Agreement
purporting to convey rights to Persons other than parties to such Credit
Agreement.

   (d) We express no opinion as to any waiver of (i) the right to a jury trial,
(ii) any objection to venue or (iii) any right to bring legal proceedings in any
court having jurisdiction.

   (e) Our opinions are limited to the laws of the State of Illinois, and we
express no opinion as to the laws of any other jurisdiction.

   This opinion letter is solely for the benefit of the addressees hereof (and
their respective successors and assigns) in connection with the transactions
contemplated by the Credit Agreements, and this opinion letter may not be relied
upon by any other Person or for any other purpose.

                             Very truly yours,
