specified herein, all accounting terms used herein shall be interpreted, all
accounting determinations hereunder shall be made, and all financial statements
required to be delivered hereunder shall be prepared in accordance with GAAP as
in effect from time to time, applied on a basis consistent (except for changes
concurred in by the Borrower's independent public accountants) with the most
recent audited consolidated financial statements of the Borrower and its
Consolidated Subsidiaries delivered to the Banks; provided that if the Borrower
                                                  --------                     
notifies the Agent that the Borrower wishes to amend Section 5.05 to eliminate
or to take into account the effect of any change in GAAP on the operation of
such covenant (or if the Agent notifies the Borrower that the Required Banks
wish to amend Section 5.05 for such purpose), then the Borrower's compliance
with such covenant shall be determined on the basis of GAAP in effect
immediately before the relevant change in GAAP became effective, until either
such notice is withdrawn or such covenant is amended in a manner satisfactory to
the Borrower and the Required Banks.

     SECTION 1.03.  Introduction of Euro.  For the avoidance of doubt, the
                    --------------------                                  
parties hereto affirm and agree that neither the fixation of the conversion rate
of any Designated Currency of a country that is a member of the European Union
against the Euro as a single currency, in accordance with the Treaty
Establishing the European Economic Community, as amended by the Treaty on the
European Union (the Maastricht Treaty), nor the conversion of any Loans or other
obligations under this Agreement from a Designated Currency of a country that is
a member of the European Union into Euros, shall require the early termination
of this Agreement or the prepayment of any amount due under this Agreement or
create any liability of one party to another party for any direct or
consequential loss arising from any of such events.  As of the date that any
such Designated Currency is no longer the lawful currency of its respective
country, all payment obligations under this Agreement that would otherwise be in
such Designated Currency shall thereafter by satisfied in Euros.

of a Base Rate Loan in Dollars to be made on the last day of such Interest
Period in a principal amount equal to the outstanding principal Dollar Amount of
such Syndicated Loan, the making of such Refunding Borrowing to be subject to

     to the provisions of the definition of Interest Period; and

          (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

     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
     with the other Money Market Loans included in such offer the principal

          (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

<PAGE>
 
     (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;
                                                                           
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.

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
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

     (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
the Borrower, the Agent and the Arranger.

     (c)  Accrued fees under subsection (a) of this Section shall be payable
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.
                    ------------------------------------------------ 

                                      23
<PAGE>
 
     (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

     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).

     financial position of the Borrower and its Consolidated Subsidiaries as of

     Consolidated Subsidiaries as of March 31, 1997 and the related unaudited

     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

     material adverse effect upon the Borrower's ability to pay and perform its

     respective terms or (ii) which in any manner draws into question the
     validity of any of the Bank Credit Documents.

     Credit Documents or for borrowings thereunder by the Borrower.

     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

     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.

     such Lien prior to a final determination of such action;

          (j) Liens for taxes not delinquent or being contested in good faith

     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
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.

     the number of days elapsed from the date an officer of the Borrower
     obtained knowledge of any Default to the date the Borrower delivered notice
     thereof to the Banks) after written notice of such failure is given to the
     Borrower by the Agent at the request of any Bank;

          (d) Misrepresentation:  the Borrower shall have made or be deemed to

              --------------------------------------------

     payable or guaranteed by it, or any interest or premium thereon, when due
     (whether by scheduled maturity, required prepayment, acceleration, demand
     or otherwise) and such failure shall continue after the applicable grace
     period, if any, specified in the agreement or instrument relating to such
     Borrowed Funds or guarantee thereof, or any event or condition shall occur
     which results in the acceleration of the maturity of any Borrowed Funds (or

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,

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

negligence or willful misconduct of the Agent.

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.

                    ---------------                                             
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.


                                 ARTICLE VIII

                            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).

                    -----------------------------------------------------------
Agreement. This Agreement may be executed in any number of counterparts, all of
---------                                                                      
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

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
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.

                                      54

     (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.

                                                 Section 3.01 of 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 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.

                                    Page 2
<PAGE>
 
     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

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

     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
                 -----------

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
                 --------

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

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

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,

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,
