deemed to represent and warrant that), after giving effect to such issuance,
amendment, renewal or extension (i) the LC Exposure shall not exceed $7,500,000
and (ii) the total Revolving Credit Exposures shall not exceed the total
Commitments.

          (c) Expiration Date.  Each Letter of Credit shall expire at or prior
              ---------------                                                 
to the close of business on the earlier of (i) the date one year after the date
of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Maturity Date.

          (d) Participations.  By the issuance of a Letter of Credit (or an
              --------------                                               
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the Issuing Bank or the Lenders, the Issuing Bank
hereby grants to each Lender, and each Lender hereby acquires from the Issuing
Bank, a participation in such Letter of Credit equal to such Lender's Applicable
Percentage of the aggregate amount available to be drawn under such Letter of
Credit.  In consideration and in furtherance of the foregoing, each Lender
hereby absolutely and unconditionally agrees to pay to the Administrative Agent,
for the account of the Issuing Bank, such Lender's Applicable Percentage of each
LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on
the date due as provided in paragraph (e) of this Section, or of any

                                       22
<PAGE>
 
reimbursement payment required to be refunded to the Borrower for any reason.
Each Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

          (e) Reimbursement.  If the Issuing Bank shall make any LC Disbursement
              -------------                                                     
in respect of a Letter of Credit, the Borrower shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC
Disbursement not later than 12:00 noon, New York City time, on the date that
such LC Disbursement is made, if the Borrower shall have received notice of such
LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if
such notice has not been received by the Borrower prior to such time on such
date, then not later than 12:00 noon, New York City time, on (i) the Business
Day that the Borrower receives such notice, if such notice is received prior to
10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day
immediately following the day that the Borrower receives such notice, if such
notice is not received prior to such time on the day of receipt; provided that
                                                                 --------     
the Borrower may, subject to the conditions to borrowing set forth herein,
request in accordance with Section 2.03 or 2.05 that such payment be financed
with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and,
to the extent so financed, the Borrower's obligation to make such payment shall
be discharged and replaced by the resulting ABR Revolving Borrowing or Swingline
Loan.  If the Borrower fails to make such payment when due, the Administrative
Agent shall notify each Lender of the applicable LC Disbursement, the payment
then due from the Borrower in respect thereof and such Lender's Applicable
Percentage thereof. Promptly following receipt of such notice, each Lender shall
pay to the Administrative Agent its Applicable Percentage of the payment then
due from the Borrower, in the same manner as provided in Section 2.07 with
respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis
                                                                    -------
mutandis, to the payment obligations of the Lenders), and the Administrative
--------                                                                    
Agent shall promptly pay to the Issuing Bank the amounts so received by it from
the Lenders.  Promptly following receipt by the Administrative Agent of any
payment from the Borrower pursuant to this paragraph, the Administrative Agent
shall distribute such payment to the Issuing Bank or, to the extent that the
Lenders have made payments pursuant to this paragraph to reimburse the Issuing
Bank, then to such Lenders and the Issuing Bank as their interests may appear.
Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing
Bank for any LC Disbursement (other than the funding of ABR Revolving Loans or a
Swingline Loan as contemplated above) shall not constitute a Loan and shall not
relieve the Borrower of its obligation to reimburse such LC Disbursement.

          (f) Obligations Absolute.  The Borrower's obligation to reimburse LC
              --------------------                                            
Disbursements as provided in paragraph (e) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of
Credit or this Agreement, or any term or provision therein, (ii) any draft or
other 

                                       23
<PAGE>
 
document presented under a Letter of Credit proving to be forged, fraudulent or
invalid in any respect or any statement therein being untrue or inaccurate in
any respect, (iii) payment by the Issuing Bank under a Letter of Credit against
presentation of a draft or other document that does not comply with the terms of
such Letter of Credit, or (iv) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the
provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff against, the Borrower's obligations hereunder. Neither
the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their
Related Parties, shall have any liability or responsibility by reason of or in
connection with the issuance or transfer of any Letter of Credit or any payment
or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Bank; provided that the foregoing shall not be construed to excuse the
              --------
Issuing Bank from liability to the Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby
waived by the Borrower to the extent permitted by applicable law) suffered by
the Borrower that are caused by the Issuing Bank's failure to exercise care when
determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. The parties hereto expressly agree that,
in the absence of gross negligence or wilful misconduct on the part of the
Issuing Bank (as finally determined by a court of competent jurisdiction), the
Issuing Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
Issuing Bank may, in its sole discretion, either accept and make payment upon
such documents without responsibility for further investigation, regardless of
any notice or information to the contrary, or refuse to accept and make payment
upon such documents if such documents are not in strict compliance with the
terms of such Letter of Credit.

          (g) Disbursement Procedures.  The Issuing Bank shall, promptly
              -----------------------                                   
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit.  The Issuing Bank shall promptly
notify the Administrative Agent and the Borrower by telephone (confirmed by
telecopy) of such demand for payment and whether the Issuing Bank has made or
will make an LC Disbursement thereunder; provided that any failure to give or
                                         --------                            
delay in giving such notice shall not relieve the Borrower of its obligation to
reimburse the Issuing Bank and the Lenders with respect to any such LC
Disbursement.

          (h) Interim Interest.  If the Issuing Bank shall make any LC
              -----------------                                       
Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that the Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to ABR Revolving Loans;
provided that, if the Borrower fails to reimburse such LC Disbursement when due
--------                                                                       
pursuant to paragraph (e) of this Section, then Section 2.13(e) shall apply.
Interest accrued pursuant to this 

                                       24
<PAGE>
 
paragraph shall be for the account of the Issuing Bank, except that interest
accrued on and after the date of payment by any Lender pursuant to paragraph (e)
of this Section to reimburse the Issuing Bank shall be for the account of such
Lender to the extent of such payment.

          (i) Replacement of the Issuing Bank.  The Issuing Bank may be replaced
              -------------------------------                                   
at any time by written agreement among the Borrower, the Administrative Agent,
the replaced Issuing Bank and the successor Issuing Bank.  The Administrative
Agent shall notify the Lenders of any such replacement of the Issuing Bank.  At
the time any such replacement shall become effective, the Borrower shall pay all
unpaid fees accrued for the account of the replaced Issuing Bank pursuant to
Section 2.12(b).  From and after the effective date of any such replacement, (i)
the successor Issuing Bank shall have all the rights and obligations of the
Issuing Bank under this Agreement with respect to Letters of Credit to be issued
thereafter and (ii) references herein to the term "Issuing Bank" shall be deemed
to refer to such successor or to any previous Issuing Bank, or to such successor
and all previous Issuing Banks, as the context shall require.  After the
replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain
a party hereto and shall continue to have all the rights and obligations of an
Issuing Bank under this Agreement with respect to Letters of Credit issued by it
prior to such replacement, but shall not be required to issue additional Letters
of Credit.

          (j) Cash Collateralization.  If any Event of Default shall occur and
              ----------------------                                          
be continuing, on the Business Day that the Borrower receives notice from the
Administrative Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, Lenders with LC Exposure representing greater than 66% of
the total LC Exposure) demanding the deposit of cash collateral pursuant to this
paragraph, the Borrower shall deposit in an account with the Administrative
Agent, in the name of the Administrative Agent and for the benefit of the
Lenders, an amount in cash equal to the LC Exposure as of such date plus any
accrued and unpaid interest thereon; provided that the obligation to deposit
                                     --------                               
such cash collateral shall become effective immediately, and such deposit shall
become immediately due and payable, without demand or other notice of any kind,
upon the occurrence of any Event of Default with respect to the Borrower
described in clause (h), (i) or (j) of Article VII.  Such deposit shall be held
by the Administrative Agent as collateral for the payment and performance of the
obligations of the Borrower under this Agreement.  The Administrative Agent
shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account.  Other than any interest earned on the investment
of such deposits, which investments shall be made at the option and sole
discretion of the Administrative Agent and at the Borrower's risk and expense,
such deposits shall not bear interest.  Interest or profits, if any, on such
investments shall accumulate in such account.  Moneys in such account shall be
applied by the Administrative Agent to reimburse the Issuing Bank for LC
Disbursements for which it has not been reimbursed and, to the extent not so
applied, shall be held for the satisfaction of the reimbursement obligations of
the Borrower for the LC Exposure at such time or, if the maturity of the Loans
has been accelerated (but subject to the consent of Lenders with LC Exposure
representing greater than 66% of the total LC Exposure), be applied to satisfy
other obligations of the Borrower under this Agreement.  If the Borrower is
required to provide an amount of cash collateral hereunder as a result of the
occurrence of an Event of 

                                       25
<PAGE>
 
Default, such amount (to the extent not applied as aforesaid) shall be returned
to the Borrower within three Business Days after all Events of Default have been
cured or waived.

      SECTION 2.07. Funding of Borrowings.
                    --------------------- 

          (a) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds by 12:00
noon, New York City time, to the account of the Administrative Agent most
recently designated by it for such purpose by notice to the Lenders; provided
                                                                     --------
that Swingline Loans shall be made as provided in Section 2.05.  The
Administrative Agent will make such Loans available to the Borrower by promptly
crediting the amounts so received, in like funds, to an account of the Borrower
maintained with the Administrative Agent in New York City and designated by the
Borrower in the applicable Borrowing Request; provided that ABR Revolving Loans
                                              --------                         
made to finance the reimbursement of an LC Disbursement as provided in Section
2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank.

          (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the
applicable Lender and the Borrower severally agree to pay to the Administrative
Agent forthwith on demand such corresponding amount with interest thereon, for
each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation or (ii) in the case of the Borrower,
the interest rate applicable to ABR Loans.  If such Lender pays such amount to
the Administrative Agent, then such amount shall constitute such Lender's Loan
included in such Borrowing.

      SECTION 2.08. Interest Elections.
                    ------------------ 

          (a) Each Dollar Revolving Borrowing initially shall be of the Type
specified in the applicable Borrowing Request and, in the case of a Eurodollar
Revolving Borrowing, shall have an initial Interest Period as specified in such
Borrowing Request.  Thereafter, the Borrower may elect to convert such Borrowing
to a different Type or to continue such Borrowing and, in the case of a
Eurodollar Revolving Borrowing, may elect Interest Periods therefor, all as
provided in this Section.  The Borrower may elect different options with respect
to different portions of the affected Borrowing, in which case each such portion
shall be allocated ratably among the Lenders holding the Loans comprising such
Borrowing, and the Loans comprising each such portion shall be considered a
separate Borrowing.  This Section shall not apply to Swingline Borrowings, which
may not be converted or continued.

                                       26
<PAGE>
 
          (b) Except as otherwise set forth herein, each Alternate Currency
Borrowing shall at all times bear interest based on the applicable Alternate
Currency Eurocurrency Rate and shall have an initial Interest Period as
specified in the initial Borrowing Request.  Thereafter, the Borrower may elect
Interest Periods therefor, all as provided in this Section.  The Borrower may
elect different Interest Periods with respect to different portions of the
affected Borrowing, in which case each such portion shall be allocated ratably
among the Lenders holding the Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing.

          (c) To make an election pursuant to this Section, the Borrower shall
notify the Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.03 if the Borrower were
requesting a Revolving Borrowing of the Type resulting from such election to be
made on the effective date of such election.  Each such telephonic Interest
Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Administrative Agent of a written Interest Election
Request in a form approved by the Administrative Agent and signed by the
Borrower.

          (d) Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02:

               (i) the Borrowing to which such Interest Election Request applies
          and, if different options are being elected with respect to different
          portions thereof, the portions thereof to be allocated to each
          resulting Borrowing (in which case the information to be specified
          pursuant to clauses (iii) and (iv) below shall be specified for each
          resulting Borrowing);

               (ii)  the effective date of the election made pursuant to such
          Interest Election Request, which shall be a Business Day;

               (iii)  whether the resulting Dollar Revolving Borrowing is to be
          an ABR Borrowing or a Eurodollar Borrowing; and

               (iv)  if the resulting Borrowing is a Eurodollar Borrowing or an
          Alternate Currency Borrowing, the Interest Period to be applicable
          thereto after giving effect to such election, which shall be a period
          contemplated by the definition of the term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing or an
Alternate Currency Borrowing but does not specify an Interest Period, then the
Borrower shall be deemed to have selected an Interest Period of one month's
duration.

          (e) Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

                                       27
<PAGE>
 
          (f) If the Borrower fails to deliver a timely Interest Election
Request with respect to a Eurodollar Revolving Borrowing prior to the end of the
Interest Period applicable thereto, then, unless such Borrowing is repaid as
provided herein, at the end of such Interest Period such Borrowing shall be
converted to an ABR Borrowing.  If the Borrower fails to deliver a timely
Interest Election Request with respect to an Alternate Currency Borrowing prior
to the end of the Interest Period applicable thereto, then, unless such
Borrowing is repaid as provided herein, at the end of such Borrowing, the
Borrower shall be deemed to have continued such Borrowing as an Alternate
Currency Eurocurrency Rate Loan and to have selected an Interest Period of one
month's duration.  Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the Administrative Agent, at the
request of the Required Lenders, so notifies the Borrower, then, so long as an
Event of Default is continuing (i) no outstanding Dollar Revolving Borrowing may
be converted to or continued as a Eurodollar Borrowing, (ii) unless repaid, each
Eurodollar Revolving Borrowing shall be converted to an ABR Borrowing at the end
of the Interest Period applicable thereto, and (iii) unless repaid, each
Alternate Currency Borrowing shall be deemed to have an Interest Period of one
month's duration following the end of the Interest Period applicable thereto.

      SECTION 2.09. Termination and Reduction of Commitments
                    ----------------------------------------

          (a) Unless previously terminated, the Commitments shall terminate on
the Maturity Date.

          (b) The Borrower may at any time terminate, or from time to time
reduce, the Commitments; provided that (i) each reduction of the Commitments
                         --------                                           
shall be in an amount that is an integral multiple of $1,000,000 and (ii) the
Borrower shall not terminate or reduce the Commitments if, after giving effect
to any concurrent prepayment of the Loans in accordance with Section 2.11, the
Revolving Credit Exposures would exceed the total Commitments.

          (c) The Borrower shall notify the Administrative Agent of any election
to terminate or reduce the Commitments under paragraph (b) of this Section at
least three Business Days prior to the effective date of such termination or
reduction, specifying such election and the effective date thereof.  Promptly
following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof.  Each notice delivered by the Borrower pursuant
to this Section shall be irrevocable; provided that a notice of termination of
                                      --------                                
the Commitments delivered by the Borrower may state that such notice is
conditioned upon the effectiveness of other credit facilities, in which case
such notice may be revoked by the Borrower (by notice to the Administrative
Agent on or prior to the specified effective date) if such condition is not
satisfied. Any termination or reduction of the Commitments shall be permanent.
Each reduction of the Commitments shall be made ratably among the Lenders in
accordance with their respective Commitments.

                                       28

      SECTION 2.10. Repayment of Loans; Evidence of Debt
                    ------------------------------------

          (a) The Borrower hereby unconditionally promises to pay (i) to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Revolving Loan on the Maturity Date and (ii) to the Swingline
Lender the then unpaid principal amount of each Swingline Loan on the earlier of
the Maturity Date and the first date after such Swingline Loan is made that is
the 15th or last day of a calendar month and is at least two Business Days after
such Swingline Loan is made; provided that on each date that a Revolving
                             --------                                   
Borrowing is made, the Borrower shall repay all Swingline Loans then
outstanding.

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

          (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Class and Type thereof
and the Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Administrative
Agent hereunder for the account of the Lenders and each Lender's share thereof.

          (d) The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and
                                    ----- -----                              
amounts of the obligations recorded therein; provided that the failure of any
                                             --------                        
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with the terms of this Agreement.

          (e) Any Lender may request that Loans made by it be evidenced by a
promissory note substantially in the form of Exhibit B.  In such event, the
                                             ---------                     
Borrower shall prepare, execute and deliver to such Lender a promissory note
payable to the order of such Lender (or, if requested by such Lender, to such
Lender and its registered assigns) and in a form approved by the Administrative
Agent.  Thereafter, the Loans evidenced by such promissory note and interest
thereon shall at all times (including after assignment pursuant to Section 9.04)
be represented by one or more promissory notes in such form payable to the order
of the payee named therein (or, if such promissory note is a registered note, to
such payee and its registered assigns).

      SECTION 2.11. Prepayment of Loans.
                    ------------------- 

          (a) The Borrower shall have the right at any time and from time to
time to prepay any Borrowing in whole or in part, subject to prior notice in
accordance with paragraph (b) of this Section.  Any prepayment pursuant to this
Section 2.11(a) shall be in an aggregate amount that is an integral multiple of
$100,000 (or the applicable Alternate Currency Equivalent thereof) and not less
than $500,000 (or the applicable Alternate Currency Equivalent thereof).

          (b) The Borrower shall be required to pay to the Administrative Agent
for the account of each Lender to be applied ratably to the prepayment of the
Loans without penalty or premium (except for LIBO Rate breakage costs, if any),
(i) the net proceeds received by the Borrower or any of its Subsidiaries from
the sale or disposition (other than in the ordinary course of business for an
aggregate consideration not exceeding $500,000 per year) of all or any part of
the assets of the Borrower or any of its Subsidiaries, (ii) the net proceeds
received by the Borrower from the issuance of any equity or Indebtedness
subordinated to the Loans hereunder, and (iii) any insurance recoveries or
condemnation awards received by the Borrower or any of its Subsidiaries which
are not applied toward the repair or replacement of the damaged or condemned
property within three months of receipt.

          (c) The Borrower shall notify the Administrative Agent (and, in the
case of prepayment of a Swingline Loan, the Swingline Lender) by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Revolving Borrowing or an Alternate Currency
Borrowing, not later than 11:00 a.m., New York City time, three Business Days
before the date of prepayment, (ii) in the case of prepayment of an ABR
Revolving Borrowing, not later than 11:00 a.m., New York City time, one Business
Day before the date of prepayment or (iii) in the case of prepayment of a
Swingline Loan, not later than 12:00 noon, New York City time, on the date of
prepayment.  Each such notice shall be irrevocable and shall specify the
prepayment date and the principal amount of each Borrowing or portion thereof to
be prepaid; provided that, if a notice of prepayment is given in connection with
            --------                                                            
a conditional notice of termination of the Commitments as contemplated by
Section 2.09, then such notice of prepayment may be revoked if such notice of
termination is revoked in accordance with Section 2.09. Promptly following
receipt of any such notice relating to a Revolving Borrowing, the Administrative
Agent shall advise the Lenders of the contents thereof.   Each partial
prepayment of any Revolving Borrowing shall be in an amount that would be
permitted in the case of an advance of a Revolving Borrowing of the same Type as
provided in Section 2.02.  Each prepayment of a Revolving Borrowing shall be
applied ratably to the Loans included in the prepaid Borrowing.  Prepayments
shall be accompanied by accrued interest to the extent required by Section 2.13.

      SECTION 2.12. Fees.
                    ---- 

          (a) The Borrower agrees to pay to the Administrative Agent for the
account of each Lender a commitment fee, which shall accrue at the Applicable
Rate on the average daily unused amount of the Commitment of such Lender during
the period ending on the date on which such Commitment terminates; provided
                                                                   --------
that, if such Lender continues to have any Revolving Credit Exposure after its
Commitment terminates, then such commitment fee shall continue to accrue on the
daily amount of such Lender's Revolving Credit Exposure from and including the
date on which its Commitment terminates to but excluding the date on which such
Lender ceases to have any Revolving Credit Exposure.  Accrued commitment fees
shall be payable in arrears on the last day of March, June, September and
December of each year and on the date on which the Commitments terminate,
commencing on the first such date to occur after the date hereof; provided that
                                                                  --------     
any commitment fees accruing after the date on which the Commitments terminate

                                       30
<PAGE>
 
shall be payable on demand.  All commitment fees shall be computed on the basis
of a year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

          (b) The Borrower agrees to pay (i) to the Administrative Agent for the
account of each Lender a participation fee with respect to its participations in
Letters of Credit, which shall accrue at the same Applicable Rate as interest on
Eurodollar Revolving Loans on the average daily amount of such Lender's LC
Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the Effective Date to but
excluding the later of the date on which such Lender's Commitment terminates and
the date on which such Lender ceases to have any LC Exposure, and (ii) to the
Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum
on the average daily amount of the LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and
including the Effective Date to but excluding the later of the date of
termination of the Commitments and the date on which there ceases to be any LC
Exposure, as well as the Issuing Bank's standard fees with respect to the
issuance, amendment, renewal or extension of any Letter of Credit or processing
of drawings thereunder.  Participation fees and fronting fees accrued through
and including the last day of March, June, September and December of each year
shall be payable on the third Business Day following such last day, commencing
on the first such date to occur after the Effective Date; provided that all such
                                                          --------              
fees shall be payable on the date on which the Commitments terminate and any
such fees accruing after the date on which the Commitments terminate shall be
payable on demand.  Any other fees payable to the Issuing Bank pursuant to this
paragraph shall be payable within 10 days after demand.  All participation fees
and fronting fees shall be computed on the basis of a year of 360 days and shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day).

          (c) The Borrower agrees to pay to the Administrative Agent, for its
own account, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Administrative Agent.

          (d) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent (or to the Issuing
Bank, in the case of fees payable to it) for distribution, in the case of
commitment fees and participation fees, to the Lenders.  Fees paid shall not be
refundable under any circumstances.

      SECTION 2.13. Interest.
                    -------- 

          (a) The Loans comprising each ABR Borrowing (including each Swingline
Loan) shall bear interest at the Alternate Base Rate plus the Applicable Rate.
                                                     ----                     

          (b) The Loans comprising each Eurodollar Borrowing shall bear interest
at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing
plus the Applicable Rate.
----                     

                                       31
<PAGE>
 
          (c) Each Alternate Currency Eurocurrency Rate Loan shall bear interest
at the applicable Alternate Currency Eurocurrency Rate for such currency for the
Interest Period in effect for such Borrowing plus the Applicable Rate.
                                             ----                     

          (d) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided in the preceding paragraphs
of this Section or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Loans as provided in paragraph (a) of this Section.

          (e) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and upon termination of the Commitments;
                                                                            
provided that (i) interest accrued pursuant to paragraph (d) of this Section
--------                                                                    
shall be payable on demand, (ii) in the event of any repayment or prepayment of
any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of
the Availability Period), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii)
in the event of any conversion of any Eurodollar Revolving Loan prior to the end
of the current Interest Period therefor, accrued interest on such Loan shall be
payable on the effective date of such conversion.

          (f) All interest hereunder shall be computed on the basis of a year of
360 days, except that interest computed by reference to the Alternate Base Rate
at times when the Alternate Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day).  The applicable Alternate Base Rate,
Adjusted LIBO Rate or Alternate Currency Eurocurrency Rate shall be determined
by the Administrative Agent, and such determination shall be conclusive absent
manifest error.

      SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of
                    --------------------------
any Interest Period for a Eurodollar Borrowing or an Alternate Currency
Borrowing:

          (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not
exist for ascertaining the Adjusted LIBO Rate or the applicable Alternate
Currency Eurocurrency Rate, as the case may be, for such Interest Period;

          (b) the Administrative Agent is advised by the Required Lenders that
the Adjusted LIBO Rate or the applicable Alternate Currency Eurocurrency Rate,
as the case may be, for such Interest Period will not adequately and fairly
reflect the cost to such Lenders (or Lender) of making or maintaining their
Loans (or its Loan) included in such Borrowing for such Interest Period; or

                                       32
<PAGE>
 
          (c) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that the Alternate Currency is not freely
transferable and convertible into dollars;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Revolving Borrowing to, or
continuation of any Revolving Borrowing as, a Eurodollar Borrowing or such
applicable Alternate Currency Borrowing, as the case may be, shall be
ineffective and (ii) if any Borrowing Request requests a Eurodollar Revolving
Borrowing or such Alternate Currency Borrowing, such Borrowing shall be made as
an ABR Borrowing; provided that if the circumstances giving rise to such notice
                  --------                                                     
affect only one Type of Borrowings, then the other Type of Borrowings shall be
permitted.

      SECTION 2.15. Increased Costs.
                    --------------- 

          (a)  If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special
          deposit or similar requirement against assets of, deposits with or for
          the account of, or credit extended by, any Lender (except any such
          reserve requirement reflected in the Adjusted LIBO Rate or the
          applicable Alternate Currency Eurocurrency Rate) or the Issuing Bank;
          or

               (ii)   impose on any Lender or the Issuing Bank or the London
          interbank market any other condition affecting this Agreement or
          Eurodollar Loans or applicable Alternate Currency Loans made by such
          Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan or applicable Alternate
Currency Loan (or of maintaining its obligation to make any such Loan) or to
increase the cost to such Lender or the Issuing Bank of participating in,
issuing or maintaining any Letter of Credit or to reduce the amount of any sum
received or receivable by such Lender or the Issuing Bank hereunder (whether of
principal, interest or otherwise), then the Borrower will pay to such Lender or
the Issuing Bank, as the case may be, such additional amount or amounts as will
compensate such Lender or the Issuing Bank, as the case may be, for such
additional costs incurred or reduction suffered.

          (b) If any Lender or the Issuing Bank determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's or the Issuing Bank's capital or on the capital
of such Lender's or the Issuing Bank's holding company, if any, as a consequence
of this Agreement or the Loans made by, or participations in Letters of Credit
held by, such Lender, or the Letters of Credit issued by the 

                                       33
<PAGE>
 
Issuing Bank, to a level below that which such Lender or the Issuing Bank or
such Lender's or the Issuing Bank's holding company could have achieved but for
such Change in Law (taking into consideration such Lender's or the Issuing
Bank's policies and the policies of such Lender's or the Issuing Bank's holding
company with respect to capital adequacy), then from time to time the Borrower
will pay to such Lender or the Issuing Bank, as the case may be, such additional
amount or amounts as will compensate such Lender or the Issuing Bank or such
Lender's or the Issuing Bank's holding company for any such reduction suffered.

          (c) A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its
holding company, as the case may be, as specified in paragraph (a) or (b) of
this Section shall be delivered to the Borrower and shall be conclusive absent
manifest error.  The Borrower shall pay such Lender or the Issuing Bank, as the
case may be, the amount shown as due on any such certificate within 10 days
after receipt thereof.

          (d) Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation; provided
                                                                       --------
that the Borrower shall not be required to compensate a Lender or the Issuing
Bank pursuant to this Section for any increased costs or reductions incurred
more than 270 days prior to the date that such Lender or the Issuing Bank, as
the case may be, notifies the Borrower of the Change in Law giving rise to such
increased costs or reductions and of such Lender's or the Issuing Bank's
intention to claim compensation therefor; provided further that, if the Change
                                          -------- -------                    
in Law giving rise to such increased costs or reductions is retroactive, then
the 270-day period referred to above shall be extended to include the period of
retroactive effect thereof.

      SECTION 2.16. Break Funding Payments.  In the event of (a) the payment 
                    ----------------------
of any principal of any Eurodollar Loan or Alternate Currency Loan other than on
the last day of an Interest Period applicable thereto (including as a result of
an Event of Default), (b) the conversion of any Eurodollar Loan or Alternate
Currency Loan other than on the last day of the Interest Period applicable
thereto, (c) the failure to borrow, convert, continue or prepay any Revolving
Loan on the date specified in any notice delivered pursuant hereto (regardless
of whether such notice may be revoked under Section 2.11(b) and is revoked in
accordance therewith), (d) the assignment of any Eurodollar Loan or Alternate
Currency Loan other than on the last day of the Interest Period applicable
thereto as a result of a request by the Borrower pursuant to Section 2.19, then,
in any such event, the Borrower shall compensate each Lender for the loss, cost
and expense attributable to such event. In the case of a Eurodollar Loan or
Alternate Currency Loan, such loss, cost or expense to any Lender shall be
deemed to include an amount determined by such Lender to be the excess, if any,
of (i) the amount of interest which would have accrued on the principal amount
of such Loan had such event not occurred, at the Adjusted LIBO Rate (in the case
of a Eurodollar Loan) or the applicable Alternate Currency Eurocurrency Rate (in
the case of an Alternate Currency Loan) that would have been applicable to such
Loan, for the period from the date of such event to the last day of the then
current Interest Period therefor (or, in the case of a failure to borrow,
convert or continue, for the period that would have been the Interest Period 

                                       34
<PAGE>
 
for such Loan), over (ii) the amount of interest which would accrue on such
principal amount for such period at the interest rate which such Lender would
bid were it to bid, at the commencement of such period, for deposits of dollars
or the applicable Alternate Currency, as the case may be, of a comparable amount
and period from other banks in the eurodollar or eurocurrency market. A
certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this Section shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

      SECTION 2.17. Taxes.
                    ----- 

          (a) Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
                                  --------                              
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) the Administrative Agent, Lender or Issuing Bank (as the
case may be) receives an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

          (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c) The Borrower shall indemnify the Administrative Agent, each Lender
and the Issuing Bank, within 10 days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent,
such Lender or the Issuing Bank, as the case may be, on or with respect to any
payment by or on account of any obligation of the Borrower hereunder (including
Indemnified Taxes or Other Taxes imposed or asserted on or attributable to
amounts payable under this Section) and any penalties, interest and reasonable
expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted
by the relevant Governmental Authority.  A certificate as to the amount of such
payment or liability delivered to the Borrower by a Lender or the Issuing Bank,
or by the Administrative Agent on its own behalf or on behalf of a Lender or the
Issuing Bank, shall be conclusive absent manifest error.

          (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

                                       35
<PAGE>
 
          (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable
law or reasonably requested by the Borrower as will permit such payments to be
made without withholding or at a reduced rate.

      SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
                    ----------------------------------------------------------- 

          (a) The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest, fees or reimbursement of LC
Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or
otherwise) prior to 12:00 noon, New York City time, on the date when due, in
immediately available funds, without set-off or counterclaim.  Any amounts
received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon.  All such payments
shall be made to the Administrative Agent at its offices at 270 Park Avenue, New
York, New York, except payments to be made directly to the Issuing Bank or
Swingline Lender as expressly provided herein and except that payments pursuant
to Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons
entitled thereto.  The Administrative Agent shall distribute any such payments
received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof.  If any payment hereunder shall be due on a
day that is not a Business Day, the date for payment shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension.  All
payments hereunder shall be made in dollars.

          (b) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully all amounts of principal, unreimbursed LC
Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, and (ii) second, towards payment of principal
and unreimbursed LC Disbursements then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of principal and unreimbursed LC
Disbursements then due to such parties.

          (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Revolving Loans or participations in LC Disbursements or
Swingline Loans resulting in such Lender receiving payment of a greater
proportion of the aggregate amount of its Revolving Loans and participations in
LC Disbursements and Swingline Loans and accrued interest thereon than the
proportion received by any other Lender, then the Lender receiving such greater
proportion shall purchase (for cash at face value) participations in the
Revolving Loans and participations in LC Disbursements and Swingline Loans of
other Lenders to the extent necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate 

                                       36
<PAGE>
 
amount of principal of and accrued interest on their respective Revolving Loans
and participations in LC Disbursements and Swingline Loans; provided that (i) if
any such participations are purchased and all or any portion of the payment
giving rise thereto is recovered, such participations shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans or
participations in LC Disbursements to any assignee or participant, other than to
the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions
of this paragraph shall apply). The Borrower consents to the foregoing and
agrees, to the extent it may effectively do so under applicable law, that any
Lender acquiring a participation pursuant to the foregoing arrangements may
exercise against the Borrower rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the
Borrower in the amount of such participation.

          (d) Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders or the Issuing Bank hereunder that the
Borrower will not make such payment, the Administrative Agent may assume that
the Borrower has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Lenders or the Issuing Bank,
as the case may be, the amount due.  In such event, if the Borrower has not in
fact made such payment, then each of the Lenders or the Issuing Bank, as the
case may be, severally agrees to repay to the Administrative Agent forthwith on
demand the amount so distributed to such Lender or Issuing Bank with interest
thereon, for each day from and including the date such amount is distributed to
it to but excluding the date of payment to the Administrative Agent, at the
greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank
compensation.

          (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.05(c), 2.06(d) or (e), 2.07(b) or 2.18(d), then the
Administrative Agent may, in its discretion (notwithstanding any contrary
provision hereof), apply any amounts thereafter received by the Administrative
Agent for the account of such Lender to satisfy such Lender's obligations under
such Sections until all such unsatisfied obligations are fully paid.

      SECTION 2.19. Mitigation Obligations; Replacement of Lenders.
                    ---------------------------------------------- 

          (a) If any Lender requests compensation under Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be,

Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment. 

         (b) If any Lender requests compensation under Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
or if any Lender defaults in its obligation to fund Loans hereunder, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
                                              -------- 
shall have received the prior written consent of the Administrative Agent (and,
if a Commitment is being assigned, the Issuing Bank and Swingline Lender), which
consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Loans and
participations in LC Disbursements and Swingline Loans, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder, from the
assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrower (in the case of all other amounts) and (iii) in the case
of any such assignment resulting from a claim for compensation under Section
2.15 or payments required to be made pursuant to Section 2.17, such assignment
will result in a reduction in such compensation or payments. A Lender shall not
be required to make any such assignment and delegation if, prior thereto, as a
result of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply.

or other information furnished by or on behalf of the Borrower to the
Administrative Agent or any Lender in connection with the negotiation of this
Agreement or delivered hereunder (as modified or supplemented by other
information so furnished) contains any material misstatement of fact or omits to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; provided that,

systems and (ii) equipment containing embedded microchips (including systems and
equipment supplied by others or with which Borrower's systems interface) and the
testing of all such systems and equipment, as so reprogrammed, will be completed
by January 1, 1999.  The cost to the Borrower of such reprogramming and testing
and of the reasonably foreseeable consequences of year 2000 to the Borrower
(including, without limitation, reprogramming errors and the failure of others'
systems or equipment) will not result in a Default or a Material Adverse Effect.
Except for such of the reprogramming referred to in this Section 3.15 as may be
necessary, the computer and management information systems of the Borrower and
its 

                                       41

to conduct its business without Material Adverse Effect.

Agent shall not have any duty to disclose, and shall not be liable for the
failure to disclose, any information relating to the Borrower or any of its
Subsidiaries that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 9.02) or in the absence of its own gross negligence or
wilful misconduct. The Administrative Agent shall be deemed not to have
knowledge of any Default unless and until written notice thereof is given to the
Administrative Agent by the Borrower or a Lender, and the Administrative Agent
shall not be responsible for or have any duty to ascertain or inquire into 
(i) any statement, warranty or representation made in or in connection with this
Agreement, (ii) the contents of any certificate, report or other document
delivered hereunder or in connection herewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other
than to confirm receipt of items expressly required to be delivered to the
Administrative Agent.

     The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon.  The Administrative Agent may consult with legal counsel (who
may be counsel for the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

     The Administrative Agent may perform any and all of its duties and exercise
its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent.  The Administrative Agent and any such sub-agent may
perform any and all of its duties and exercise its rights and powers through
their respective Related Parties.  The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent.

     Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph, the Administrative Agent may resign at any
time by notifying the Lenders, the Issuing Bank and the Borrower.  Upon any such
resignation, the Required Lenders shall have the right, in consultation with the
Borrower, to appoint a successor.  If no successor shall have been 

                                       55
<PAGE>
 
so appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Administrative Agent gives notice of its
resignation, then the retiring Administrative Agent may, on behalf of the
Lenders and the Issuing Bank, appoint a successor Administrative Agent which
shall be a bank with an office in New York, New York, or an Affiliate of any
such bank. Upon the acceptance of its appointment as Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrower and such successor. After the
Administrative Agent's resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in
respect of any actions taken or omitted to be taken by any of them while it was
acting as Administrative Agent.

     Each Lender acknowledges that it has, independently and without reliance
upon the Administrative Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement.  Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any related agreement or any
document furnished hereunder or thereunder.

     Each of the Lenders hereby agrees that Fleet National Bank shall have the
title of "Documentation Agent" under this Agreement, but shall have no duties,
responsibilities or obligations, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Documentation Agent.  The parties
hereto acknowledge and agree that all duties, responsibilities and obligations
under this Agreement shall be performed by the Administrative Agent.

      SECTION 9.02. Waivers; Amendments.
                    -------------------

          (a) No failure or delay by the Administrative Agent, the Issuing Bank
or any Lender in exercising any right or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the Administrative Agent, the
Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of
any rights or remedies that they would otherwise have.  No waiver of any
provision of this Agreement or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be effec
tive only in the specific instance and for the purpose for which given.  Without
limiting the generality of the foregoing, the making of a Loan or issuance of a
Letter of Credit shall not be construed as a waiver of any Default, regardless
of whether the Administrative Agent, any Lender or the Issuing Bank may have had
notice or knowledge of such Default at the time.

          (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders or by the Borrower and the
Administrative Agent with the consent of the Required Lenders; provided that no
                                                               --------        
such agreement shall amend, modify or otherwise affect the rights or duties of
the Administrative Agent, the Issuing Bank or the Swingline Lender hereunder
without the prior written consent of the Administrative Agent, the Issuing Bank
or the Swingline Lender, as the case may be.

      SECTION 9.03. Expenses; Indemnity; Damage Waiver.
                    ----------------------------------

          (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Administrative Agent and its Affiliates, including the
reasonable fees, charges and disbursements of counsel for the Administrative
Agent, in connection with the syndication of the credit facilities provided for
herein, the preparation and administration of this Agreement or any amendments,
modifications or waivers of the provisions hereof (whether or not the
transactions contemplated hereby or thereby shall be consummated), (ii) all
reasonable out-of-pocket expenses incurred by the Issuing Bank in connection
with the issuance, amendment, renewal or extension of any Letter of Credit or
any demand for payment thereunder and (iii) all out-of-pocket expenses incurred
by the Administrative Agent, the Issuing Bank or any Lender, including the fees,
charges and disbursements of any counsel for the Administrative Agent, the
Issuing Bank or any Lender, in connection with the enforcement or protection of
its rights in connection with this Agreement, including its rights under this
Section, or in connection with the Loans made or Letters of Credit issued
hereunder, including all such out-of-pocket expenses incurred during any
workout, restructuring or negotiations in respect of such Loans or Letters of
Credit.

          (b) The Borrower shall indemnify the Administrative Agent, the Issuing
Bank and each Lender, and each Related Party of any of the foregoing Persons
(each such Person being called an "Indemnitee") against, and hold each
                                   ----------                         
Indemnitee harmless from, any and all losses, claims, damages, liabilities and
related expenses, including the fees, charges and disbursements of any counsel
for any Indemnitee, incurred by or asserted against any Indemnitee arising out
of, in connection with, or as a result of (i) the execution or delivery of this
Agreement or any agreement or instrument contemplated hereby, the performance by
the parties hereto of their respective obligations hereunder or the consummation
of the Transactions or any other transactions contemplated hereby, (ii) any Loan
or Letter of Credit or the use of the proceeds therefrom (including any refusal
by the Issuing Bank to honor a demand for payment under a Letter of Credit if
the documents presented in connection with such demand do not strictly comply
with the terms of such Letter of Credit), (iii) any actual or alleged presence
or release of Hazardous Materials on or from any property owned or operated by
the Borrower or any of its Subsidiaries, or any Environmental Liability related
in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that such
                                                         --------          
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses resulted from the gross
negligence or wilful misconduct of such Indemnitee.

          (c) To the extent that the Borrower fails to pay any amount required
to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline
Lender under paragraph (a) or (b) of this Section, each Lender severally agrees
to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as
the case may be, such Lender's Applicable Percentage (determined as of the time
that the applicable unreimbursed expense or indemnity payment is sought) of such
unpaid amount; provided that the unreimbursed expense or indemnified loss,
               --------                                                   

                                       58
<PAGE>
 
claim, damage, liability or related expense, as the case may be, was incurred by
or asserted against the Administrative Agent, the Issuing Bank or the Swingline
Lender in its capacity as such.

          (d) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

          (e) All amounts due under this Section shall be payable not later than
three days after written demand therefor.

      SECTION 9.04. 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
permitted hereby (including any Affiliate of the Issuing Bank that issues any
Letter of Credit), except that the Borrower may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Borrower without
such consent shall be null and void).  Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit) and, to the
extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

          (b) Any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Commitment and the Loans at the time owing to it); provided  that (i) except
                                                       --------                 
in the case of an assignment to a Lender or an Affiliate of a Lender, each of
the Borrower (except in the case an Event of Default shall have occurred and be
continuing) and the Administrative Agent (and, in the case of an assignment of
all or a portion of a Commitment or any Lender's obligations in respect of its
LC Exposure or Swingline Exposure, the Issuing Bank and the Swingline Lender)
must give their prior written consent to such assignment (which consent shall
not be unreasonably withheld), (ii) except in the case of an assignment to a
Lender or an Affiliate of a Lender or an assignment of the entire remaining
amount of the assigning Lender's Commitment, the amount of the Commitment of the
assigning Lender subject to each such assignment (determined as of the date the
Assignment and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $5,000,000 unless each of the
Borrower and the Administrative Agent otherwise consent, (iii) each partial
assignment shall be made as an assignment of a proportionate part of all the
assigning Lender's rights and obligations under this Agreement, (iv) the parties
to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Acceptance, together with a processing and recordation fee of
$3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; and provided further 
                                                          -------- ------- 

                                       59
<PAGE>
 
that any consent of the Borrower otherwise required under this paragraph shall
not be required if an Event of Default under clause (h) or (i) of Article VII
has occurred and is continuing. Subject to acceptance and recording thereof
pursuant to paragraph (d) of this Section, from and after the effective date
specified in each Assignment and Acceptance the assignee thereunder shall be a
party hereto and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender under this Agreement,
and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of the assigning Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this paragraph shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section.

          (c) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans and LC Disbursements owing to, each Lender
pursuant to the terms hereof from time to time (the "Register").  The entries in
                                                     --------                   
the Register shall be conclusive, and the Borrower, the Administrative Agent,
the Issuing Bank and the Lenders may treat each Person whose name is recorded in
the Register pursuant to the terms hereof as a Lender hereunder for all purposes
of this Agreement, notwithstanding notice to the contrary.  The Register shall
be available for inspection by the Borrower, the Issuing Bank and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

          (d) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section and any written consent to such assignment required by paragraph
(b) of this Section, the Administrative Agent shall accept such Assignment and
Acceptance and record the information contained therein in the Register.  No
assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

          (e) Any Lender may, without the consent of the Borrower, the
Administrative Agent, the Issuing Bank or the Swingline Lender, sell
participations to one or more banks or other entities (a "Participant") in all
                                                          -----------         
or a portion of such Lender's rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided that (i) such Lender's obligations under this Agreement shall remain
--------                                                                     
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Borrower, the
Administrative Agent, the Issuing Bank and the other Lenders shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement.  Any agreement or instrument
pursuant to which a Lender sells 

                                       60
<PAGE>
 
such a participation shall provide that such Lender shall retain the sole right
to enforce this Agreement and to approve any amendment, modification or waiver
of any provision of this Agreement; provided that such agreement or instrument
                                    --------
may provide that such Lender will not, without the consent of the Participant,
agree to any amendment, modification or waiver described in the first proviso to
Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this
Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 9.08 as though it were a Lender, provided
such Participant agrees to be subject to Section 2.18(c) as though it were a
Lender.

          (f) A Participant shall not be entitled to receive any greater payment
under Section 2.15 or 2.17 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent.  A Participant that would be a Foreign Lender if it were
a Lender shall not be entitled to the benefits of Section 2.17 unless the
Borrower is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Borrower, to comply with Section
2.17(e) as though it were a Lender.

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

      SECTION 9.05. Survival. All covenants, agreements, representations and
                    --------
warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the
Administrative Agent, the Issuing Bank or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid or any
Letter of Credit is outstanding and so long as the Commitments have not expired
or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article
VIII shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof.

      SECTION 9.09. Counterparts; Integration; Effectiveness. This Agreement may
                    ----------------------------------------
be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative
Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof. Except as provided in
Section 4.01, this Agreement shall become effective when it shall have been
executed by the Administrative Agent and when the Administrative Agent shall
have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

      SECTION 9.07. Severability. Any provision of this Agreement held to be
                    ------------
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

      SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred
                    ---------------
and be continuing, each Lender and each of its Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations at any time owing
by such Lender or Affiliate to or for the credit or the account of the Borrower
against any of and all the obligations of the Borrower now or hereafter existing
under this Agreement held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender under this Section are
in addition to other rights and remedies (including other rights of setoff)
which such Lender may have.

      SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process.
                    ----------------------------------------------------------

          (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

          (b) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such Federal court.  Each of
the parties hereto agrees that a final judgment 

                                       62
<PAGE>
 
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law. Nothing in this Agreement shall affect any right that the Administrative
Agent, the Issuing Bank or any Lender may otherwise have to bring any action or
proceeding relating to this Agreement against the Borrower or its properties in
the courts of any jurisdiction.

          (c) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any court referred to in
paragraph (b) of this Section.  Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

          (d) The Borrower hereby agrees that service of all writs, complaints,
process and summonses in any suit, action or proceeding arising out of or
relating to this Agreement, or for recognition or enforcement of any judgment,
may be made upon Cambridge (the "Process Agent") with an office on the date
                                 -------------                             
hereof at 304 Vassar Street, Cambridge, Massachusetts 02139. The Borrower hereby
irrevocably appoints the Process Agent its true and lawful attorney-in-fact in
its name, place and stead to accept such service of any and all such writs,
complaints, process and summonses.  The Borrower agrees that any election by the
Administrative Agent or any Lender to give notice of any such service to the
Borrower shall not impair or affect the validity of such service or of the
judgment based thereon.

          (e) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01.  Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

      SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
                    --------------------
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     SECTION 9.11. Judgment Currency. If, for the purpose of obtaining judgment
                   -----------------
in any court or obtaining an order enforcing a judgment, it becomes necessary to
convert any amount due under this Agreement into any Alternate Currency, then
the conversion shall be made at the spot exchange rate therefor as quoted by the
Administrative Agent as of 11:00 a.m., London time, on 

                                       63
<PAGE>
 
the date three Business Days prior to the date on which the judgment is given or
the order is made, as the case may be. In the event that there is a difference
between the rate of exchange on the basis of which the amount of such judgment
or order is determined and the rate of exchange prevailing on the date of
payment, the Borrower hereby agrees to pay such additional amount as may be
necessary to ensure that the amount paid is the amount of such Alternate
Currency which permits the Administrative Agent to purchase the amount of
dollars due under this Agreement when the judgment or order is issued at the
Administrative Agent's spot exchange rate for buying dollars with the Alternate
Currency, in accordance with normal banking procedures, prevailing at the
opening of business on the date of payment. Any amount due from the Borrower to
the Administrative Agent for the account of each Lender under the second
sentence of this Section 9.11 will be due as separate debt of the Borrower to
the Administrative Agent for the account of each Lender and shall not be
affected by any judgment or order being obtained for any other sum. The covenant
in this Section 9.11 shall survive the payment in full of all of the other
obligations of the Borrower hereunder.

     SECTION 9.12. No Offset. All payments by the Borrower hereunder shall be
                   ---------
made without setoff or counterclaim and free and clear of and without deduction
for any foreign or domestic taxes, levies, imposts, duties, charges, fees,
deductions, withholdings, compulsory loans, restriction or conditions of any
nature now or hereafter imposed or levied by any jurisdiction or any political
subdivision thereof or taxing or other authority therein unless the Borrower is
required by law to make such deduction or withholding. Except as otherwise
expressly provided in this Section 9.12, if any such obligation is imposed upon
the Borrower with respect to any amount payable hereunder, the Borrower will pay
to the Administrative Agent for the account of each Lender, on the date on which
such amount is due and payable hereunder, such additional amount in dollars as
shall be necessary to enable the Administrative Agent to receive the same net
amount which it would have received on such due date had no such obligation been
imposed upon the Borrower. The Borrower will deliver promptly to the
Administrative Agent, certificates or other valid vouchers for all taxes or
other charges deducted from or paid with respect to payments made by the
Borrower hereunder.

      SECTION 9.13. Headings. Article and Section headings and the Table of
                    --------
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

      SECTION 9.14. Confidentiality. Each of the Administrative Agent, the
                    ---------------
Issuing Bank and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to
its and its Affiliates' directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party to this Agreement, (e) in
connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder,
(f) subject to an agreement containing provisions 

                                       64
<PAGE>
 
substantially the same as those of this Section, to any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (g) with the consent of the Borrower
or (h) to the extent such Information (i) becomes publicly available other than
as a result of a breach of this Section or (ii) becomes available to the
Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis
from a source other than the Borrower. For the purposes of this Section,
"Information" means all information received from the Borrower relating to the
------------                                                                  
Borrower or its business, other than any such information that is available to
the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential
basis prior to disclosure by the Borrower; provided that, in the case of
                                           --------                     
information received from the Borrower after the date hereof, such information
is clearly identified at the time of delivery as confidential.  Any Person
required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its obligation to do so if
such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

      SECTION 9.15. Interest Rate Limitation. Notwithstanding anything herein to
                    ------------------------
the contrary, if at any time the interest rate applicable to any Loan, together
with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively the "Charges"), shall exceed the maximum
                                        -------                            
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
                  ------------                                               
received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.
