           -----------------                                               
subject to a Eurodollar Pricing Option:

          (a) on any date on which the Leverage Ratio is less than 25% or on
     which the Company has a senior unsecured long-term debt rating issued and
     maintained by S&P or Moody's ("Senior Debt Rating") equal to or higher than
                                    ------------------

                                          -------                           
     percent (.350%);

          (b) on any date on which the Leverage Ratio is equal to or greater

     equal to BB+ from S&P or Ba1 from Moody's ("Level II"), nine-twentieths of
                                                 --------                      
     one percent (.450%);

          (c) on any date on which the Leverage Ratio is equal to or greater
     than 35% and less than 45% or on which the Company has a Senior Debt Rating
     equal to BB from S&P or Ba2 from Moody's ("Level III"), eleven-twentieths
                                                ---------                     
     of one percent (.550%);

          (d) on any date on which the Leverage Ratio is equal to or greater
     than 45% and less than 55% or on which the Company has a Senior Debt Rating
     equal to or lower than BB- from S&P or Ba3 from Moody's ("Level IV"),

     three-quarters of one percent (.750%);

          (e) on any date on which the Leverage Ratio is equal to or greater

                                  -------                             

          (f) on any date on which the Leverage Ratio is equal to or greater
     than  60% ("Level VI"), one percent (1.000%).
                 --------                         

Notwithstanding the foregoing, in the event that on any date (i) the Level
indicated by the Leverage Ratio and the Level indicated by the Senior Debt
Rating (such Levels to be determined as indicated in the next sentence in case
the Company receives a split rating from S&P and 


                                      -2-
<PAGE>
 
Moody's) are one Level apart, the Applicable Margin shall be determined based on
the lower of such two Levels and (ii) the Level indicated by the Leverage Ratio
and the Level indicated by the Senior Debt Rating are more than one Level apart,
the Applicable Margin shall be determined based on the Level one below the
higher of such two Levels. In the event that on any date (x) the Level indicated
by the S&P rating and the Level indicated by the Moody's rating are one Level
apart, the Level indicated by the Senior Debt Rating to be used for purposes of
the preceding sentence shall be the lower of such two Levels and (y) the Level
indicated by the S&P rating and the Level indicated by the Moody's rating are
more than one Level apart, the Level indicated by the Senior Debt Rating to be
used for purposes of the preceding sentence shall be the Level one below the
higher of such two Levels.

     By way of example, if the Company has a Senior Debt Rating of BBB- from S&P
and a Senior Debt Rating of Ba1 from Moody's, the Level indicated by the Senior
Debt Rating to be used for purposes of determining the Applicable Margin shall
be Level I and if the Company has a Senior Debt Rating of BBB- from S&P and a
Senior Debt Rating of Ba3 from Moody's, the Level indicated by the Senior Debt
Rating to be used for purposes of determining the Applicable Margin shall be
Level III.  Similarly, if the Leverage Ratio is less than 25% such that the
Level indicated by the Leverage Ratio is Level I and the Level indicated by the
Senior Debt Rating is Level II, the Applicable Margin shall be the pricing
determined by Level I and if the Leverage Ratio is less than 25% such that the
Level indicated by the Leverage Ratio is Level I and the Level indicated by the
Senior Debt Rating is Level IV, the Applicable Margin shall be the pricing
determined by Level III.

     For purposes of calculating the Applicable Margin, (i) the Leverage Ratio
shall be determined (A) as at the end of the most recent January, April, July or
October for which financial statements have been furnished (or are required to
have been furnished) by the Company to the Lenders pursuant to Section 6.4.1,
6.4.2 or 7.2.1 and (B) upon the consummation of any acquisition (giving effect
to such acquisition and the financing thereof) in connection with which the
Company is required to provide to the Lenders a certificate of a Financial
Officer pursuant to Section 6.9 and (ii) any adjustment in the Applicable Margin
shall be prospective and shall take effect on the fifth Business Day following
either the date upon which the financial statements referred to in the foregoing
clause (i) are furnished (or are required to be furnished) by the Company to the

Account") which the Swingline Lender shall administer as follows:  (a) the
-------

the Swingline Lender in maximum principal amount equal to the Swingline Loan.

          2.2.4.  Conversion of Swingline Loan into Revolving Loan.  On any
                  ------------------------------------------------         
Banking Day after the occurrence and during the continuance of an Event of
Default, the Swingline Lender may, in its sole discretion, give notice to the
other Lenders and the Company that the Swingline Loan shall be paid in full with
a mandatory borrowing under the Revolving Loan (the "Mandatory Borrowing").
                                                     -------------------    
Such a notice of a Mandatory Borrowing shall be deemed to have been
automatically given upon a Bankruptcy Default or upon the exercise of any of the
remedies provided in Section 8.2.  Upon the giving of any such notice or deemed
notice, a Mandatory Borrowing under the Revolving Loan in the amount of the
Swingline Loan shall be made on the next Banking Day from all Lenders in
accordance with their respective Percentage Interests in the Revolving Loan, and
the proceeds thereof shall be applied to the Swingline Lender as a repayment of
the Swingline Loan.  Each Lender irrevocably agrees to make such loan pursuant
to each such Mandatory Borrowing notice in the amount and in the manner
specified above in this Section 2.2.4,

satisfied, (b) that a Default or an Event of Default has occurred and is
continuing or (c) the date of such Mandatory Borrowing. In the event that any
Mandatory Borrowing cannot for any reason be made on the date required above
(including as a result of the commencement of a proceeding under the Bankruptcy
Code), each Lender shall promptly purchase from the Swingline Lender as of the
date the Mandatory Borrowing otherwise would have occurred such participation in
the Swingline Loan as shall be necessary to cause the Lenders to share in the
Swingline Loan ratably based upon their respective Percentage Interests in the
Revolving Loan. In the event of such participations, all interest payable on the
Swingline Loan shall be for the account of the Swingline Lender until the date
on which the participations are required to be purchased and, to the extent
attributable to the purchased participations, shall be payable to the
participants from and after such date. At the time any such purchase of
participations is actually made, the purchasing Lender shall pay the Swingline
Lender interest on the principal amount of the participation purchased at the
overnight Federal Funds Rate for each day, commencing with the date the
Mandatory Borrowing otherwise would have occurred, to the date of payment for
such participation.

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

the Letter of Credit Issuer and the Company may agree upon at the time such
Letter of Credit is issued and shall include a requirement of not less than
three Banking Days after presentation of a draft before payment must be made
thereunder.

     2.4.4.  Lenders' Participation in Letters of Credit.  Upon the issuance
             -------------------------------------------                    
of any Letter of Credit, a participation therein, in an amount equal to each
Lender's Percentage Interest, shall automatically be deemed granted by the
Letter of Credit Issuer to each Lender on the date of such issuance and the
Lenders shall automatically be obligated, as set forth in Section 12.4, to
reimburse the Letter of Credit Issuer to the extent of their respective
Percentage Interests for all obligations incurred by the Letter of Credit Issuer
to third parties in respect of such Letter of Credit not reimbursed by the
Company.  The Letter of Credit Issuer will send to each Lender (and the Agent if
the Letter of Credit Issuer is not the Agent) a confirmation regarding the
participations in Letters of Credit outstanding during such month.

     2.4.5.  Presentation.  The Letter of Credit Issuer may accept or pay any
             ------------                                                    
draft presented to it, regardless of when drawn and whether or not negotiated,
if such draft, the other required documents and any transmittal advice are
presented to the Letter of Credit Issuer and dated on or before the expiration
date of the Letter of Credit under which such draft is drawn.  Except insofar as
instructions actually received may be given by the Company in writing expressly
to the contrary with regard to, and prior to, the Letter of Credit Issuer's
issuance of any Letter of Credit for the account of the Company and such
contrary instructions are reflected in such Letter of Credit, the Letter of
Credit Issuer may honor as complying with the terms of the Letter of Credit and

any payment on a draft presented or accepted under a Letter of Credit, the
Company will on demand pay to such Letter of Credit Issuer in immediately
available funds the amount of such payment. Unless the Company shall otherwise
pay to the Letter of Credit Issuer the amount required by the foregoing
sentence, any such amount paid prior to the Final Maturity Date shall be
considered a loan under Section 2.1.1 and part of the Revolving Loan. So long as
no Default shall exist or be created thereby, the addition of such amount to the
Revolving Loan pursuant to the preceding sentence shall constitute payment for
the purposes of this Section 2.4.6.

the Letter of Credit Issuer except to the extent otherwise provided herein, in
any Letter of Credit or in any other Credit Document.  Anything in the Uniform
Customs and Practice to the contrary notwithstanding:

     (a) Neither the Company nor any beneficiary of any Letter of Credit shall
be deemed an agent of any Letter of Credit Issuer.

     (b) With respect to each Letter of Credit, neither the Letter of Credit
Issuer nor its correspondents shall be responsible for or shall have any duty to
ascertain:

         (i)    the genuineness of any signature;

         (ii)   the validity, form, sufficiency, accuracy, genuineness or legal
     effect of any endorsements;

         (iii)  delay in giving, or failure to give, notice of arrival, notice
     of refusal of documents or of discrepancies in respect of which any Letter
     of Credit Issuer refuses the documents or any other notice, demand or
     protest;

         (iv)   the performance by any beneficiary under any Letter of Credit of
     such beneficiary's obligations to the Company;

         (v)    inaccuracy in any notice received by the Letter of Credit

     amount of any instrument on the reverse of such Letter of Credit or to
     surrender such Letter of Credit or to forward documents in the manner
     required by such Letter of Credit.

     (c)  The occurrence of any of the events referred to in the Uniform Customs
and Practice or in the preceding clauses of this Section 2.4.7 shall not affect
or prevent the vesting of any of the Letter of Credit Issuer's rights or powers
hereunder or the Company's obligation to make reimbursement of amounts paid
under any Letter of Credit or any draft accepted thereunder.

     (d)  Upon receipt, the Company will promptly examine (i) each Letter of
Credit (and any amendments thereof) sent to it by the Letter of Credit Issuer
and (ii) all instruments and documents delivered to it from time to time by the
Letter of Credit Issuer. The Company will notify the Letter of Credit Issuer of
any claim of noncompliance by notice actually received within 36 hours
(excluding hours included in non-Banking Days) after receipt of any of the
foregoing documents, the Company being conclusively deemed to have waived any
such claim against such Letter of Credit Issuer and its correspondents unless
such notice is given.

     (e)  In the event of any conflict between the provisions of this Agreement
and the Uniform Customs and Practice, the provisions of this Agreement shall
govern.

such action as the Letter of Credit Issuer may reasonably request, including
requesting the beneficiary of any Letter of Credit to execute such documents as
the Letter of Credit Issuer may reasonably request, to assure and confirm to the
Letter of Credit Issuer such subrogation and such rights, including the rights,
if any, of the beneficiary to whom such payment is made in accounts receivable,
inventory and other properties and assets of any Obligor.

     2.4.9.  Modification, Consent, etc.  If the Company requests or consents in
             --------------------------                                      
writing to any modification or extension of any Letter of Credit, or waives in
writing any failure of any draft, certificate or other document to comply with

the Lender so failing to perform and the Percentage Interests shall be

obligations to make the extensions of credit contemplated by Section 2 may, if
any such Lender so desires, assume, in such proportions as such Lenders may
agree, the obligations of any Lender who has so failed and the Percentage
Interests shall be appropriately adjusted. The provisions of this Section 2.6

per annum which shall at all times equal the Applicable Rate.  Prior to any
stated or accelerated maturity of the Revolving Loan, the Company will, on each
Payment Date, pay the accrued and unpaid interest on the portion of the
Revolving Loan which was not subject to a Eurodollar Pricing Option.  On the
last day of each Eurodollar Interest Period or on any earlier termination of any
Eurodollar Pricing Option, the Company will pay the accrued and unpaid interest
on the portion of the Revolving Loan which was subject to the Eurodollar Pricing
Option which expired or terminated on such date.  In the case of any Eurodollar
Interest Period longer than three months, the Company will also pay the accrued
and unpaid interest on the portion of the Revolving Loan subject to the
Eurodollar Pricing Option having such Eurodollar Interest Period at three-month
intervals, the first such payment to be made on the last Banking Day of the
three-month period which begins on the first day of such Eurodollar Interest
Period.  On the stated or any accelerated maturity of the Revolving Loan, the
Company will pay all accrued and unpaid interest on the Revolving Loan,
including any accrued and unpaid interest on any portion of the Revolving Loan
which is subject to a Eurodollar Pricing Option.  The Swingline Loan shall
accrue and bear interest at a rate per annum which shall at all times equal the
Swingline Rate.  Interest on the Swingline Loan shall be calculated on a daily
basis and on the basis of a year of 360 days.  Prior to any stated or
accelerated maturity of the Swingline Loan, the Company will on each Wednesday,
beginning on the first Wednesday after the Restatement Date, pay the accrued and
unpaid interest, if any, on such Indebtedness.  On any stated or accelerated
maturity of the Swingline Loan all accrued and unpaid interest thereon shall be
forthwith due and payable.  All payments of interest hereunder in respect of the
Swingline Loan shall be made by the Company to the Agent for the account of the
Swingline Lender.  In addition, the Company will on demand pay interest on any
overdue installments of principal and, to the extent not prohibited by
applicable law, on any overdue installments of interest, fees and any other
overdue amounts owed under any Credit Document at a rate per annum equal to the
sum of 2% plus the highest Applicable Rate then in effect or at a rate per annum
          ----                                                                  
equal to the sum of 2% plus the Swingline Rate then in effect in the case of
                       ----                                                 
overdue installments of principal and interest with respect to a Swingline Loan
(the "Overdue Rate").  All payments of interest hereunder shall be made to the
      ------------                                                            
Agent for the account of each Lender in accordance with such Lender's Percentage
Interest.

     3.2  Eurodollar Pricing Options.
          -------------------------- 

          3.2.1.  Election of Eurodollar Pricing Options.  Subject to all of the
                  --------------------------------------                        
terms and conditions hereof and so long as no Default exists, the Company may
from time to time, by irrevocable notice to the Agent actually received not less
than three Banking Days prior to the commencement of the Eurodollar Interest
Period selected in such notice, elect to have such portion of the Loan as the
Company may specify in such notice accrue and bear interest during the
Eurodollar Interest Period so selected at the Applicable Rate computed on the
basis of the Eurodollar Rate.  No such election shall become effective:


                                      -30-
<PAGE>
 
          (a) if, prior to the commencement of any such Eurodollar Interest
     Period, the Agent determines that (i) the electing or granting of the
     Eurodollar Pricing Option in question would violate a Legal Requirement,
     (ii) Eurodollar deposits in an amount comparable to the principal amount of
     the Loan as to which such Eurodollar Pricing Option has been elected and
     which have a term corresponding to the proposed Eurodollar Interest Period
     are not readily available in the inter-bank Eurodollar market, or (iii) by
     reason of circumstances affecting the inter-bank Eurodollar market,
     adequate and reasonable methods do not exist for ascertaining the interest
     rate applicable to such deposits for the proposed Eurodollar Interest
     Period; or

          (b) if any Lender shall have advised the Agent by telephone or
     otherwise at or prior to noon (Boston time) on the second Banking Day prior
     to the commencement of such proposed Eurodollar Interest Period (and shall
     have subsequently confirmed in writing) that, after reasonable efforts to
     determine the availability of such Eurodollar deposits, such Lender
     reasonably anticipates that Eurodollar deposits in an amount equal to the
     Percentage Interest of such Lender in the portion of the Loan as to which
     such Eurodollar Pricing Option has been elected and which have a term
     corresponding to the Eurodollar Interest Period in question will not be
     offered in the Eurodollar market to such Lender.

          3.2.2.  Notice to Lenders and Company.  The Agent will promptly inform
                  -----------------------------                                 
each Lender (by telephone or otherwise) of each notice received by it from the
Company pursuant to Section 3.2.1 and of the Eurodollar Interest Period
specified in such notice. Upon determination by the Agent of the Eurodollar Rate
for such Eurodollar Interest Period or in the event such election shall not
become effective, the Agent will promptly notify the Company and each Lender (by
telephone or otherwise) of the Eurodollar Rate so determined or why such
election did not become effective, as the case may be.

          3.2.3.  Selection of Eurodollar Interest Periods.  Eurodollar Interest
                  ----------------------------------------                      
Periods shall be selected so that:

          (a) the minimum portion of the Loan subject to any Eurodollar Pricing
     Option shall be $1,000,000 and an integral multiple of $500,000;

          (b) no more than ten Eurodollar Pricing Options shall be outstanding
     at any one time; and

          (c) no Eurodollar Interest Period with respect to any part of the Loan
     subject to a Eurodollar Pricing Option shall expire later than the Final
     Maturity Date.

          3.2.4.  Additional Interest.  If any portion of the Loan subject to a
                  -------------------                                          
Eurodollar Pricing Option is repaid, or any Eurodollar Pricing Option is
terminated for any reason (including acceleration of maturity), on a date which
is prior to the last Banking Day of the 


                                      -31-
<PAGE>
 
Eurodollar Interest Period applicable to such Eurodollar Pricing Option, the
Company will pay to the Agent for the account of each Lender in accordance with
such Lender's Percentage Interest, in addition to any amounts of interest
otherwise payable hereunder, an amount equal to the present value (calculated in
accordance with this Section 3.2.4) of interest for the unexpired portion of
such Eurodollar Interest Period on the portion of the Loan so repaid, or as to
which a Eurodollar Pricing Option was so terminated, at a per annum rate equal
to the excess, if any, of (a) the rate applicable to such Eurodollar Pricing
Option minus (b) the lowest rate of interest obtainable by the Agent upon the
       -----                       
purchase of debt securities customarily issued by the Treasury of the United
States of America which have a maturity date approximating the last Banking Day
of such Eurodollar Interest Period. The present value of such additional
interest shall be calculated by discounting the amount of such interest for each
day in the unexpired portion of such Eurodollar Interest Period from such day to
the date of such repayment or termination at a per annum interest rate equal to
the interest rate determined pursuant to clause (b) of the preceding sentence,
and by adding all such amounts for all such days during such period. The
determination by the Agent of such amount of interest shall, in the absence of
demonstrable error, be conclusive. For purposes of this Section 3.2.4, if any
portion of the Loan which was to have been subject to a Eurodollar Pricing
Option is not outstanding on the first day of the Eurodollar Interest Period
applicable to such Eurodollar Pricing Option other than for reasons described in
Section 3.2.1, the Company shall be deemed to have terminated such Eurodollar
Pricing Option.

     3.2.5.  Violation of Legal Requirements.  If any Legal Requirement shall
             -------------------------------                                 
prevent any Lender from funding or maintaining through the purchase of deposits
in the interbank Eurodollar market any portion of the Loan subject to a
Eurodollar Pricing Option or otherwise from giving effect to such Lender's
obligations as contemplated by Section 3.2, (a) the Agent may by notice to the
Company describing such Legal Requirement terminate all of the affected
Eurodollar Pricing Options, (b) the portion of the Loan subject to such
terminated Eurodollar Pricing Options shall immediately bear interest thereafter
at the Applicable Rate computed on the basis of the Base Rate and (c) the
Company shall make any payment required by Section 3.2.4.

     3.2.6.  Funding Procedure.  The Lenders may fund any portion of the Loan
             -----------------                                               
subject to a Eurodollar Pricing Option out of any funds available to the
Lenders.  Regardless of the source of the funds actually used by any of the
Lenders to fund any portion of the Loan subject to a Eurodollar Pricing Option,
however, all amounts payable hereunder, including the interest rate applicable
to any such portion of the Loan and the amounts payable under Sections 3.2.4,
3.5, 3.6, 3.7 and 3.8, shall be computed as if each Lender had actually funded
such Lender's Percentage Interest in such portion of the Loan through the
purchase of deposits in such amount of the type by which the Eurodollar Basic
Rate was determined with a maturity the same as the applicable Eurodollar
Interest Period relating thereto and through the transfer of such deposits from
an office of the Lender having the same location 


                                      -32-
<PAGE>
 
     as the applicable Eurodollar Office to one of such Lender's offices in the
     United States of America.

     3.3  Facility Fees.  In consideration of the Lenders' commitments to make
          -------------                                                       
the extensions of credit provided for in Section 2, while such commitments are
outstanding, the Company will pay to the Agent for the account of the Lenders in
accordance with the Lenders' respective Percentage Interests, on each Payment
Date and on the Final Maturity Date, an amount equal to interest computed at a
rate per annum equal to the Facility Fee Rate on the average daily Maximum
Amount of Revolving Credit during the quarter or portion thereof ending on such
Payment Date or, as the case may be, the Final Maturity Date; provided, however,
                                                              --------  ------- 
that the first such payment shall be for the period beginning on the Restatement
Date and ending on the first Payment Date.

     3.4  Letter of Credit Fees.  The Company will pay to the Agent for the
          ---------------------                                            
account of each of the Lenders, in accordance with the Lenders' respective
Percentage Interests, on each Payment Date and on the Final Maturity Date, a
Letter of Credit fee equal to interest at a rate per annum equal to the Letter
of Credit Fee Rate on the average daily Letter of Credit Exposure during the
quarter or portion thereof ending on such Payment Date or, as the case may be,
the Final Maturity Date; provided, that if any Letter of Credit or any extension
of a Letter of Credit would produce a fee hereunder that is less than $250
during the term of such Letter of Credit or extension, the fee owing to the
Lenders hereunder with respect to such Letter of Credit or extension shall be
$250.  The Company also will pay to the Letter of Credit Issuer (i) on the date
of issuance of each Letter of Credit an issuance fee of $150 with respect to
such Letter of Credit, (ii) on each Payment Date and on the Final Maturity Date,
an additional Letter of Credit fee equal to interest at the rate of one-eighth
of one percent (1/8%) per annum on the average daily Letter of Credit Exposure
during the quarter or portion thereof ending on such Payment Date or, as the
case may be, the Final Maturity Date and (iii) as invoiced, other customary
service charges and expenses for the services of the Letter of Credit Issuer in
connection with the Letters of Credit at the times and in the amounts from time
to time in effect in accordance with its general rate structure, including fees
and expenses relating to issuance, amendment, negotiation, cancellation and
similar operations.

     3.5  Reserve Requirements, etc.  If any Legal Requirement shall (a) impose,
          -------------------------                                             
modify, increase or deem applicable any insurance assessment, reserve, special
deposit or similar requirement against any Funding Liability or the Letters of
Credit, (b) impose, modify, increase or deem applicable any other requirement or
condition with respect to any Funding Liability or the Letters of Credit, or (c)
change the basis of taxation of Funding Liabilities or payments in respect of
any Letter of Credit (other than changes in the rate of taxes measured by the
overall net income of such Lender) and the effect of any of the foregoing shall
be to increase the cost to any Lender of issuing, making, funding or maintaining
its respective Percentage Interest in any portion of the Loan subject to a
Eurodollar Pricing Option or any Letter of Credit, to reduce the amounts
received or receivable by such Lender under this Agreement or to require such
Lender to make any payment or forego any amounts otherwise payable to such
Lender under this Agreement, then, within 15 days after the receipt by the
Company of a certificate from such Lender setting forth 


                                      -33-
<PAGE>
 
why it is claiming compensation under this Section 3.5 and computations (in
reasonable detail) of the amount thereof, the Company shall pay to the Agent for
the account of such Lender such additional amounts as are specified by such
Lender in such certificate as sufficient to compensate such Lender for such
increased cost or such reduction, together with interest at the Overdue Rate on
such amount from the 15th day after receipt of such certificate until payment in
full thereof; provided, however, that the foregoing provisions shall not apply
              --------  ------- 
to any Tax or to any reserves which are included in computing the Eurodollar
Reserve Rate. The determination by such Lender of the amount of such costs
shall, in the absence of demonstrable error, be conclusive. The Company shall be
entitled to replace any such Lender in accordance with Section 13.3.

     3.6  Taxes.  All payments of the Credit Obligations shall be made without
          -----                                                               
set-off or counterclaim and free and clear of any deductions, including
deductions for Taxes, unless the Company is required by law to make such
deductions.  If (a) any Lender shall be subject to any Tax with respect to any
payment of the Credit Obligations or its obligations hereunder or (b) the
Company shall be required to withhold or deduct any Tax on any payment on the
Credit Obligations, within 15 days after the receipt by the Company of a
certificate from such Lender setting forth why it is claiming compensation under
this Section 3.6 and computations (in reasonable detail) of the amount thereof,
the Company shall pay to the Agent for such Lender's account such additional
amount as is necessary to enable such Lender to receive the amount of Tax so
imposed on the Lender's obligations hereunder or the full amount of all payments
which it would have received on the Credit Obligations (including amounts
required to be paid under Sections 3.5, 3.7, 3.8 and this Section 3.6) in the
absence of such Tax, as the case may be, together with interest at the Overdue
Rate on such amount from the 15th day after receipt of such certificate until
payment in full thereof.  Whenever Taxes must be withheld by the Company with
respect to any payments of the Credit Obligations, the Company shall promptly
furnish to the Agent for the account of the applicable Lender official receipts
(to the extent that the relevant governmental authority delivers such receipts)
evidencing payment of any such Taxes so withheld. If the Company fails to pay
any such Taxes when due or fails to remit to the Agent for the account of the
applicable Lender the required receipts evidencing payment of any such Taxes so
withheld or deducted, the Company shall indemnify the affected Lender for any
incremental Taxes and interest or penalties that may become payable by such
Lender as a result of any such failure.  The determination by such Lender of the
amount of such Tax and the basis therefor shall, in the absence of demonstrable
error, be conclusive.  The Company shall be entitled to replace any such Lender
in accordance with Section 13.3.

     3.7  Capital Adequacy.  If any Lender shall determine that compliance by
          ----------------                                                   
such Lender with any Legal Requirement regarding capital adequacy of banks or
bank holding companies has or would have the effect of reducing the rate of
return on such Lender's capital as a consequence of such Lender's commitment to
make the extensions of credit contemplated hereby, or such Lender's maintenance
of the extensions of credit contemplated hereby, to a level below that which
such Lender could have achieved but for such compliance (taking into
consideration such Lender's policies with respect to capital adequacy
immediately before such compliance and assuming that such Lender's capital was
fully utilized prior to such compliance) by an amount deemed by such 


                                      -34-
<PAGE>
 
Lender to be material, then, within 15 days after the receipt by the Company of
a certificate from such Lender setting forth why it is claiming compensation
under this Section 3.7 and computations (in reasonable detail) of the amount
thereof, the Company shall pay to the Agent for the account of such Lender such
additional amounts as shall be sufficient to compensate such Lender for such
reduced return, together with interest at the Overdue Rate on each such amount
from the 15th day after receipt of such certificate until payment in full
thereof. The determination by such Lender of the amount to be paid to it and the
basis for computation thereof shall, in the absence of demonstrable error, be
conclusive. In determining such amount, such Lender may use any reasonable
averaging, allocation and attribution methods. The Company shall be entitled to
replace any such Lender in accordance with Section 13.3.

     3.8  Regulatory Changes.  If any Lender shall determine that (a) any change
          ------------------                                                    
in any Legal Requirement (including any new Legal Requirement) after the date
hereof shall directly or indirectly (i) reduce the amount of any sum received or
receivable by such Lender with respect to the Loan or the Letters of Credit or
the return to be earned by such Lender on the Loan or the Letters of Credit,
(ii) impose a cost on such Lender or any Affiliate of such Lender that is
attributable to the making or maintaining of, or such Lender's commitment to
make, its portion of the Loan or the Letters of Credit, or (iii) require such
Lender or any Affiliate of such Lender to make any payment on, or calculated by
reference to, the gross amount of any amount received by such Lender under any
Credit Document, and (b) such reduction, increased cost or payment shall not be
fully compensated for by an adjustment in the Applicable Rate or the Letter of
Credit fees, then, within 15 days after the receipt by the Company of a
certificate from such Lender setting forth why it is claiming compensation under
this Section 3.8 and computations (in reasonable detail) of the amount thereof,
the Company shall pay to such Lender such additional amounts as such Lender
determines will, together with any adjustment in the Applicable Rate, fully
compensate for such reduction, increased cost or payment, together with interest
on such amount from the 15th day after receipt of such certificate until payment
in full thereof at the Overdue Rate.  The determination by such Lender of the
amount to be paid to it and the basis for computation thereof hereunder shall,
in the absence of demonstrable error, be conclusive.  In determining such
amount, such Lender may use any reasonable averaging and attribution methods.
The Company shall be entitled to replace any such Lender in accordance with
Section 13.3.

     3.9  Computations of Interest and Fees.  For purposes of this Agreement,
          ---------------------------------                                  
interest, facility fees and Letter of Credit fees (and any other amount
expressed as interest or such fees) shall be computed on the basis of a 360-day
year for actual days elapsed.  If any payment required by this Agreement becomes
due on any day that is not a Banking Day, such payment shall, except as
otherwise provided in the Eurodollar Interest Period, be made on the next
succeeding Banking Day.  If the due date for any payment of principal is
extended as a result of the immediately preceding sentence, interest shall be
payable for the time during which payment is extended at the Applicable Rate or,
in the case of principal of the Swingline Loan, at the Swingline Rate.

Maximum Amount of Revolving Credit, the Company will within three Banking Days
pay the amount of such excess to the Agent for the account of the Lenders. If at
any time the Swingline Loan exceeds $10,000,000, the Company will within three
Banking Days pay the amount of such excess to the Swingline Lender.

          4.2.2.  Letter of Credit Exposure.  If at any time the Letter of
                  ------------------------- 
Credit Exposure exceeds the limits set forth in Section 2.4, the Company will
promptly pay the amount of such excess to the Agent for the account of the
Lenders to be applied as provided in Section 4.6.

     4.3  [Intentionally Omitted].

     4.4  [Intentionally Omitted].

     4.5  Voluntary Prepayments.  In addition to the prepayments required by
          ---------------------                                             
Section 4.2, the Company may from time to time prepay all or any portion of the
Revolving Loan (in a minimum amount of $1,000,000 and an integral multiple of
$100,000), without premium or penalty of any type (except as provided in Section
3.2.4 with respect to the early termination of Eurodollar Pricing Options).  The
Company shall give the Agent at least three Banking Days prior notice of its
intention to prepay, specifying the date of payment, the total amount of the
Loan to be paid on such date and the amount of interest to be paid with such
prepayment.  At any time or from time to time upon telephone notice to the
Swingline Lender, given not later than 3:00 p.m. (Boston time) on any Banking
Day, the Company shall have the right to prepay, without premium or penalty of
any type, all or any part of the outstanding principal amount of its Swingline

     Agent as beneficiary and issued by a bank and on terms reasonably

Exposure issued for the account of the Company.  Any such cash so deposited and
the cash proceeds of any draw under any standby letter of credit so furnished,
including any interest thereon, shall be returned by the Agent to the Company
only when, and to the extent that, the amount of such cash held by the Agent
exceeds the Letter of Credit Exposure at a time when no Default exists;
provided, however, that if an Event of Default occurs and the Credit Obligations
--------  -------

shall be applied first to the portion thereof not then subject to Eurodollar
Pricing Options, then the balance of any such prepayment shall be applied to the

     the results of their operations for the periods covered thereby. The
     unaudited Consolidating financial statements referred to in clause (a)
     above and the unaudited Consolidated financial statements referred to in

or creates a material risk of resulting, in any Material Adverse Change or which
seeks to enjoin the consummation, or which questions the validity, of any of the
transactions contemplated by this Agreement or any other Credit Document.  No
judgment, decree or order of any court, board or other governmental or
administrative agency or any arbitrator has been issued against or binds the
Company or any of its Subsidiaries which has resulted, or creates a material

         8.1.11 Subordinated Debentures.  There shall occur any "Event of
                -----------------------                                  
Default" as defined in Section 13.1 of the Subordinated Debentures Agreement, or
any of the Credit Obligations shall fail to be "Superior Indebtedness" within
the meaning of Section 10 of the Subordinated Debentures Agreement.

     8.2  Certain Actions Following an Event of Default.  If any one or more
          ---------------------------------------------                     
Events of Default shall occur, then in each and every such case:

          8.2.1 Terminate Obligation to Extend Credit.  The Agent on behalf of
                -------------------------------------                         
the Lenders may (and upon written request of the Required Lenders the Agent
shall) terminate the obligations of the Lenders to make any further extensions
of credit under the Credit Documents by furnishing notice of such termination to
the Company.

          8.2.2 Specific Performance; Exercise of Rights.  The Agent on behalf
                ----------------------------------------                      
of the Lenders may (and upon written request of the Required Lenders the Agent
shall) proceed to protect and enforce the Lenders' rights by suit in equity,
action at law and/or other appropriate proceeding, either for specific
performance of any covenant or condition contained in this Agreement or any
other Credit Document or in any instrument or assignment delivered to the
Lenders pursuant to this Agreement or any other Credit Document, or in aid of
the exercise of any power granted in this Agreement or any other Credit Document
or any such instrument or assignment.

          8.2.3 Acceleration.  The Agent on behalf of the Lenders may (and upon
                ------------                                                   
written request of the Required Lenders the Agent shall) by notice in writing to
the Company (a) declare all or any part of the unpaid balance of the Credit
Obligations then outstanding to be immediately due and payable, and (b) require
the Company immediately to deposit with the Agent in cash an amount equal to the
then Letter of Credit Exposure (which cash shall be held and applied as provided
in Section 4.5), and thereupon such unpaid balance or part thereof and such
amount equal to the Letter of Credit Exposure shall become so due and payable
without presentation, protest or further demand or notice of any kind, all of
which are hereby expressly waived; provided, however, that if a Bankruptcy
                                   --------  -------                      
Default shall have occurred, the unpaid balance of the Credit Obligations shall
automatically become immediately due and payable.

          8.2.4 Enforcement of Payment; Credit Security; Setoff.  The Agent on
                -----------------------------------------------               
behalf of the Lenders may (and upon written request of the Required Lenders the
Agent shall) proceed to enforce payment of the Credit Obligations in such manner
as it may elect, to cancel, or instruct other Letter of Credit Issuers to
cancel, any outstanding Letters of Credit which permit the cancellation thereof
and to realize upon any and all rights in the

                                      -68-
<PAGE>
 
     Credit Security. The Lenders may offset and apply toward the payment of the
     Credit Obligations (and/or toward the curing of any Event of Default) any
     Indebtedness from the Lenders to the respective Obligors, including any
     Indebtedness represented by deposits in any account maintained with the
     Lenders, regardless of the adequacy of any security for the Credit
     Obligations. The Lenders shall have no duty to determine the adequacy of
     any such security in connection with any such offset.

         8.2.5. Cumulative Remedies.  To the extent not prohibited by applicable
                -------------------                                             
     law which cannot be waived, all of the Lenders' rights hereunder and under
     each other Credit Document shall be cumulative.

     8.3 Annulment of Defaults.  Once an Event of Default has occurred, such
         ---------------------                                              
Event of Default shall be deemed to exist and be continuing for all purposes of
the Credit Documents until the Required Lenders or the Agent (with the consent
of the Required Lenders) shall have waived such Event of Default in writing,
stated in writing that the same has been cured to such Lenders' reasonable
satisfaction or entered into an amendment to this Agreement which by its express
terms cures such Event of Default, at which time such Event of Default shall no
longer be deemed to exist or to have continued.  No such action by the Lenders
or the Agent shall extend to or affect any subsequent Event of Default or impair
any rights of the Lenders upon the occurrence thereof. The making of any
extension of credit during the existence of any Default or Event of Default
shall not constitute a waiver thereof.

     8.4 Waivers.  To the extent that such waiver is not prohibited by the
         -------                                                          
provisions of applicable law that cannot be waived, each of the Company and the
other Obligors waives:

         (a) all presentments, demands for performance, notices of
     nonperformance (except to the extent required by this Agreement or any
     other Credit Document), protests, notices of protest and notices of
     dishonor;

         (b) any requirement of diligence or promptness on the part of any
     Lender in the enforcement of its rights under this Agreement, the Notes or
     any other Credit Document;

         (c) any and all notices of every kind and description which may be
     required to be given by any statute or rule of law; and

         (d) any defense (other than indefeasible payment in full) which it may
     now or hereafter have with respect to its liability under this Agreement,
     the Notes or any other Credit Document or with respect to the Credit
     Obligations.

 9.  Guarantees.
     ---------- 

     9.1 Guarantees of Credit Obligations.  Each Guarantor unconditionally
         --------------------------------                                 
jointly and severally guarantees that the Credit Obligations will be performed
and will be paid in full in cash

                                     -69-
<PAGE>
 
when due and payable, whether at the stated or accelerated maturity thereof or
otherwise, this guarantee being a guarantee of payment and not of collectability
and being absolute and in no way conditional or contingent. In the event any
part of the Credit Obligations shall not have been so paid in full when due and
payable, each Guarantor will, immediately upon notice by the Agent or, without
notice, immediately upon the occurrence of a Bankruptcy Default, pay or cause to
be paid to the Agent for the account of each Lender in accordance with the
Lenders' respective Percentage Interests the amount of such Credit Obligations
which are then due and payable and unpaid. The obligations of each Guarantor
hereunder shall not be affected by the invalidity, unenforceability or
irrecoverability of any of the Credit Obligations as against any other Obligor,
any other guarantor thereof or any other Person. For purposes hereof, the Credit
Obligations shall be due and payable when and as the same shall be due and
payable under the terms of this Agreement or any other Credit Document
notwithstanding the fact that the collection or enforcement thereof may be
stayed or enjoined under the Bankruptcy Code or other applicable law.

     9.2  Continuing Obligation.  Each Guarantor acknowledges that the Lenders
          ---------------------                                               
and the Agent have entered into this Agreement (and, to the extent that the
Lenders or the Agent may enter into any future Credit Document, will have
entered into such agreement) in reliance on this Section 9 being a continuing
irrevocable agreement, and such Guarantor agrees that its guarantee may not be
revoked in whole or in part.  The obligations of the Guarantors hereunder shall
terminate when the commitment of the Lenders to extend credit under this
Agreement shall have terminated and all of the Credit Obligations have been
indefeasibly paid in full in cash and discharged; provided, however, that:
                                                  --------  -------       

          (a) if a claim is made upon the Lenders at any time for repayment or
     recovery of any amounts or any property received by the Lenders from any
     source on account of any of the Credit Obligations and the Lenders repay or
     return any amounts or property so received (including interest thereon to
     the extent required to be paid by the Lenders) or

          (b) if the Lenders become liable for any part of such claim by reason
     of (i) any judgment or order of any court or administrative authority
     having competent jurisdiction, or (ii) any settlement or compromise of any
     such claim of which the Company has notice and an opportunity to comment,

then the Guarantors shall remain liable under this Agreement for the amounts so
repaid or property so returned or the amounts for which the Lenders become
liable (such amounts being deemed part of the Credit Obligations) to the same
extent as if such amounts or property had never been received by the Lenders,
notwithstanding any termination hereof or the cancellation of any instrument or
agreement evidencing any of the Credit Obligations.  Not later than five days
after receipt of notice from the Agent, the Guarantors shall jointly and
severally pay to the Agent an amount equal to the amount of such repayment or
return for which the Lenders have so become liable.  Payments hereunder by a
Guarantor may be required by the Agent on any number of occasions.

                                     -70-

     9.3  Waivers with Respect to Credit Obligations.  Except to the extent
          ------------------------------------------                       
expressly required by this Agreement or any other Credit Document, each
Guarantor waives, to the fullest extent permitted by the provisions of
applicable law, all of the following (including all defenses, counterclaims and
other rights of any nature based upon any of the following):

          (a) presentment, demand for payment and protest of nonpayment of any
     of the Credit Obligations, and notice of protest, dishonor or
     nonperformance;

          (b) notice of acceptance of this guarantee and notice that credit has
     been extended in reliance on the Guarantor's guarantee of the Credit
     Obligations;

          (c) notice of any Default or of any inability to enforce performance
     of the obligations of the Company or any other Person with respect to any
     Credit Document, or notice of any acceleration of maturity of any Credit
     Obligations;

          (d) demand for performance or observance of, and any enforcement of
     any provision of, the Credit Obligations, this Agreement or any other
     Credit Document or any pursuit or exhaustion of rights or remedies with
     respect to any Credit Security or against the Company or any other Person
     in respect of the Credit Obligations or any requirement of diligence or
     promptness on the part of the Agent or the Lenders in connection with any
     of the foregoing;

          (e) any act or omission on the part of the Agent or the Lenders which
     may impair or prejudice the rights of the Guarantor, including rights to
     obtain subrogation, exoneration, contribution, indemnification or any other
     reimbursement from the Company or any other Person, or otherwise operate as
     a deemed release or discharge;

          (f) failure or delay to perfect or continue the perfection of any
     security interest in any Credit Security or any other action which harms or
     impairs the value of, or any failure to preserve or protect the value of,
     any Credit Security;

          (g) any statute of limitations or any statute or rule of law which
     provides that the obligation of a surety must be neither larger in amount
     nor in other respects more burdensome than the obligation of the principal;

          (h) any "single action" or "anti-deficiency" law which would otherwise
     prevent the Lenders from bringing any action, including any claim for a
     deficiency, against the Guarantor before or after the Agent's or the
     Lenders' commencement or completion of any foreclosure action, whether
     judicially, by exercise of power of sale or otherwise, or any other law
     which would otherwise require any election of remedies by the Agent or the
     Lenders;

          (i) all demands and notices of every kind with respect to the
     foregoing; and

                                     -71-
<PAGE>
 
          (j)   to the extent not referred to above, all defenses (other than
     payment) which the Company may now or hereafter have to the payment of the
     Credit Obligations, together with all suretyship defenses, which could
     otherwise be asserted by such Guarantor.

Each Guarantor represents that it has obtained the advice of counsel as to the
extent to which suretyship and other defenses may be available to it with
respect to its obligations hereunder in the absence of the waivers contained in
this Section 9.3.

     No delay or omission on the part of the Agent or the Lenders in exercising
any right under this Agreement or any other Credit Document or under any
guarantee of the Credit Obligations or with respect to the Credit Security shall
operate as a waiver or relinquishment of such right. No action which the Agent
or the Lenders or the Company may take or refrain from taking with respect to
the Credit Obligations, including any amendments thereto or modifications
thereof or waivers with respect thereto, shall affect the provisions of this
Agreement or the obligations of the Guarantor hereunder.  None of the Lenders'
or the Agent's rights shall at any time in any way be prejudiced or impaired by
any act or failure to act on the part of any Obligor, or by any noncompliance by
the Company with the terms, provisions and covenants of this Agreement,
regardless of any knowledge thereof which the Agent or the Lenders may have or
otherwise be charged with.

     9.4  Lenders' Power to Waive, etc.  Each Guarantor grants to the Lenders
          ----------------------------                                       
full power in their discretion, without notice to or consent of such Guarantor,
such notice and consent being expressly waived to the fullest extent permitted
by applicable law, and without in any way affecting the liability of the
Guarantor under its guarantee hereunder:

          (a)   To waive compliance with, and any Default under, and to consent
     to any amendment to or modification or termination of any terms or
     provisions of, or to give any waiver in respect of, this Agreement, any
     other Credit Document, the Credit Security, the Credit Obligations or any
     guarantee thereof (each as from time to time in effect);

          (b)   To grant any extensions of the Credit Obligations (for any
     duration), and any other indulgence with respect thereto, and to effect any
     total or partial release (by operation of law or otherwise), discharge,
     compromise or settlement with respect to the obligations of the Obligors or
     any other Person in respect of the Credit Obligations, whether or not
     rights against the Guarantor under this Agreement are reserved in
     connection therewith;

          (c)   To take security in any form for the Credit Obligations, and to
     consent to the addition to or the substitution, exchange, release or other
     disposition of, or to deal in any other manner with, any part of any
     property contained in the Credit Security whether or not the property, if
     any, received upon the exercise of such power shall be of a character or
     value the same as or different from the character or value of any property

                                     -72-
<PAGE>
 
     disposed of, and to obtain, modify or release any present or future
     guarantees of the Credit Obligations and to proceed against any of the
     Credit Security or such guarantees in any order;

          (d)   To collect or liquidate or realize upon any of the Credit
     Obligations or the Credit Security in any manner or to refrain from
     collecting or liquidating or realizing upon any of the Credit Obligations
     or the Credit Security; and

          (e)   To extend credit under this Agreement, any other Credit Document
     or otherwise in such amount as the Lenders may determine, including
     increasing the amount of credit and the interest rate and fees with respect
     thereto, even though the condition of the Obligors (financial or otherwise
     on an individual or Consolidated basis) may have deteriorated since the
     date hereof.

     9.5  Information Regarding the Company, etc.  Each Guarantor has made such
          --------------------------------------                               
investigation as it deems desirable of the risks undertaken by it in entering
into this Agreement and is fully satisfied that it understands all such risks.
Each Guarantor waives any obligation which may now or hereafter exist on the
part of the Agent or the Lenders to inform it of the risks being undertaken by
entering into this Agreement or of any changes in such risks and, from and after
the date hereof, each Guarantor undertakes to keep itself informed of such risks
and any changes therein.  Each Guarantor expressly waives any duty which may now
or hereafter exist on the part of the Agent or the Lenders to disclose to the
Guarantor any matter related to the business, operations, character, collateral,
credit, condition (financial or otherwise), income or prospects of the Company
or its Affiliates or their properties or management, whether now or hereafter
known by the Agent or the Lenders.  Each Guarantor represents, warrants and
agrees that it assumes sole responsibility for obtaining from the Company all
information concerning this Agreement and all other Credit Documents and all
other information as to the Company and its Affiliates or their properties or
management as such Guarantor deems necessary or desirable.

     9.6  Certain Guarantor Representations.  Each Guarantor represents that:
          ---------------------------------                                  

          (a)   it is in its best interest and in pursuit of the purposes for
     which it was organized as an integral part of the business conducted and
     proposed to be conducted by the Company and its Subsidiaries, and
     reasonably necessary and convenient in connection with the conduct of the
     business conducted and proposed to be conducted by them, to induce the
     Lenders to enter into this Agreement and to extend credit to the Company by
     making the Guarantees contemplated by this Section 9,

          (b)   the credit available hereunder will directly or indirectly inure
     to its benefit,

          (c)   by virtue of the foregoing it is receiving at least reasonably
     equivalent value from the Lenders for its Guarantee,

                                     -73-
<PAGE>
 
          (d)   it will not be rendered insolvent as a result of entering into
     this Agreement,

          (e)   after giving effect to the transactions contemplated by this
     Agreement, it will have assets having a fair saleable value in excess of
     the amount required to pay its probable liability on its existing debts as
     they become absolute and matured,

          (f)   it has, and will have, access to adequate capital for the
     conduct of its business,

          (g)   it has the ability to pay its debts from time to time incurred
     in connection therewith as such debts mature, and

          (h)   it has been advised by the Agent that the Lenders are unwilling
     to enter into this Agreement unless the Guarantees contemplated by this
     Section 9 are given by it.

     9.7  Subrogation.  Each Guarantor agrees that, until the Credit Obligations
          -----------                                                           
are paid in full, it will not exercise any right of reimbursement, subrogation,
contribution, offset or other claims against the other Obligors arising by
contract or operation of law in connection with any payment made or required to
be made by such Guarantor under this Agreement.  After the payment in full of
the Credit Obligations, each Guarantor shall be entitled to exercise against the
Company and the other Obligors all such rights of reimbursement, subrogation,
contribution and offset, and all such other claims, to the fullest extent
permitted by law.

     9.8  Subordination.  Each Guarantor covenants and agrees that, after the
          -------------                                                      
occurrence of an Event of Default, all Indebtedness, claims and liabilities then
or thereafter owing by the Company or any other Obligor to such Guarantor
whether arising hereunder or otherwise are subordinated to the prior payment in
full of the Credit Obligations and are so subordinated as a claim against such
Obligor or any of its assets, whether such claim be in the ordinary course of
business or in the event of voluntary or involuntary liquidation, dissolution,
insolvency or bankruptcy, so that no payment with respect to any such
Indebtedness, claim or liability will be made or received while any Event of
Default exists.

     9.9  Future Subsidiaries; Further Assurances.  The Company will from time
          ---------------------------------------                             
to time cause (a) any present Wholly Owned Subsidiary that is not a Guarantor
within 30 days after notice from the Agent or (b) any future Wholly Owned
Subsidiary within 30 days after any such Person becomes a Wholly Owned
Subsidiary, to join this Agreement as a Guarantor pursuant to a joinder
agreement in form and substance satisfactory to the Agent.  Each Guarantor will,
promptly upon the request of the Agent from time to time, execute, acknowledge
and deliver, and file and record, all such instruments, and take all such
action, as the Agent deems necessary or advisable to carry out the intent and
purposes of this Section 9.

     (all such Indebtedness being referred to as the "Pledged Indebtedness").
                                                      --------------------   

          10.1.4.   Proceeds and Products.  All proceeds, including insurance
                    ---------------------                                    
     proceeds, and products of the items of Credit Security described or
     referred to in Sections 10.1.1 through 10.1.3 and, to the extent not
     included in the foregoing, all Distributions with respect to the Pledged
     Securities.
 
          10.1.5.   Excluded Property.  Notwithstanding Sections 10.1.1 through

     10.1.4, the payment and performance of the Credit Obligations shall not be
     secured by:

<PAGE>
 
          (a)     any rights arising under, and any property, tangible or
     intangible, acquired under, any agreement which validly prohibits the
     creation by such Obligor of a security interest in such rights or property;

          (b)     any rights or property to the extent that any valid and
     enforceable law or regulation applicable to such rights or property
     prohibits the creation of a security interest therein; or

          (c)     more than 66% of the outstanding stock or other equity in any
     foreign Subsidiary.

     10.2 [Intentionally Omitted].

     10.3 Representations, Warranties and Covenants with Respect to Credit
          ----------------------------------------------------------------
Security.  Each Obligor represents, warrants and covenants that:
--------                                                        

          10.3.1  Pledged Stock.  All shares of capital stock, limited 
                  -------------                                        
partnership interests, membership interests, beneficial interests and similar
securities included in the Pledged Stock are and shall be at all times duly
authorized, validly issued, fully paid and (in the case of capital stock and
limited partnership interests) nonassessable. Each Obligor will deliver to the
Agent certificates representing any Pledged Stock represented by a certificate,
accompanied by a stock transfer power executed in blank and, if the Agent so
requests, with the signature guaranteed, all in form and manner satisfactory to
the Agent. Pledged Stock that is not evidenced by a certificate will be
registered in the Agent's name as pledgee on the issuer's records, all in form
and substance satisfactory to the Agent. At any time after the occurrence of an
Event of Default, the Agent may transfer into its name or the name of its
nominee, as pledgee, any Pledged Securities. In the event the Pledged Stock
includes any Margin Stock, the Obligors will furnish to the Lenders Federal
Reserve Form U-1 and take such other action as the Agent may request to ensure
compliance with applicable laws.

          10.3.2  Pledged Indebtedness. All Pledged Indebtedness owed by any 
                  --------------------                                       
Affiliate of the Obligors shall be on open account and shall not be evidenced by
any note or other instrument; provided, however, that all Pledged Indebtedness
                              --------  -------                               
owed by any Obligor shall, if the Agent requests, be evidenced by a promissory
note, which note shall be delivered to the Agent after having been endorsed in
blank.  Each Obligor will, immediately upon the receipt thereof, deliver to the
Agent any promissory note or similar instrument representing any Pledged
Indebtedness, after having endorsed such promissory note or instrument in blank.

          10.3.3  [Intentionally Omitted].

                                     -76-
<PAGE>
 
          10.3.4.   No Liens or Restrictions on Transfer or Change of Control.  
                    ---------------------------------------------------------
All Credit Security shall be free and clear of any Liens and restrictions on the
transfer thereof, including contractual provisions which prohibit the assignment
of rights under contracts, except for Liens permitted by Section 6.8. Without
limiting the generality of the foregoing, each Obligor will exclude from
contracts to which it becomes a party after the date hereof (other than
partnership and joint venture agreements) provisions that would prevent such
Obligor from creating a security interest in such contract or any property
acquired thereunder as contemplated hereby. None of the Pledged Stock is subject
to any adverse claims, option to purchase or similar rights of any Person.
Except with the written consent of the Agent, no Obligor is, and none of them
will be, party to or bound by any agreement, instrument, deed or lease that
restricts the change of control or ownership, or the creation of a security
interest in the ownership, of the Company or any of its Subsidiaries (other than
a Subsidiary which is a partnership).

          10.3.5.   [Intentionally Omitted].

          10.3.6.   Trade Names.  No Obligor will adopt or do business under any
                    -----------                                                 
name other than its name or names designated in Exhibit 7.1 or any other name
specified by notice actually received by the Agent not less than ten Banking
Days prior to the conduct of business under such additional name.  Since its
incorporation, no Obligor has changed its corporate name or adopted or conducted
business under any trade name other than a name specified on Exhibit 7.1.

          10.3.7.   [Intentionally Omitted].

          10.3.8.   Modifications to Credit Security.  Except with the prior 
                    --------------------------------     
written consent of the Agent, no Obligor shall amend or modify, or waive any of
its rights under or with respect to, any Pledged Securities if the effect of
such amendment, modification or waiver would be to reduce the amount of any such
items or to extend the time of payment thereof, to waive any default by any
other party thereto, or to waive or impair any remedies of the Obligors or the
Lenders under or with respect to any Pledged Securities, in each case other than
consistent with past practice in the ordinary course of business and on an 
arm's-length basis. Each Obligor will promptly give the Agent written notice of
any request by any Person for any credit or adjustment with respect to any
Pledged Securities.

          10.3.9.   Delivery of Documents.  At the Agent's request, each Obligor
                    ---------------------                                       
shall deliver to the Agent, promptly upon such Obligor's receipt thereof, copies
of any agreements, instruments, documents or invoices comprising or relating to
the Credit Security.  Pending such request, such Obligor shall keep such items
at its chief executive office and principal place of business, which office and
place of business shall be set forth in Exhibit 7.1, or at such other address as
such Obliger may specify by notice actually received by the Agent not less than
ten Banking Days prior to such change of address.

          10.3.10.   Perfection of Credit Security.  Upon the Agent's request 
                     ----------------------------- 
      from time to time, the Obligors will execute and deliver, and file and
      record in the proper filing and recording places, all such instruments,
      including financing statements, collateral assignments of copyrights,
      trademarks and patents, mortgages or deeds of trust, and notations on
      certificates of title and will take all such other action, as the Agent
      deems advisable for confirming to it the Credit Security or to carry out
      any other purposes of this Agreement or any other Credit Document.

      10.4 Administration of Credit Security.  The Credit Security shall be
           ---------------------------------                               
administered as follows; and if an Event of Default shall have occurred, Section
10.5 shall also apply.

          10.4.1.    Use of Credit Security.  Until the Agent provides written 
                     ----------------------
      notice to the contrary, each Obligor may use, commingle and dispose of any
      part of the Credit Security in the ordinary course of its business, all
      subject to Section 6.11.

          10.4.2.   [Intentionally Omitted].

          10.4.3.    Pledged Securities.
                     ------------------ 

          (a)       Distributions.
                    ------------- 

                    (i)   Until an Event of Default shall occur, the respective
          Obligors shall be entitled to receive all Distributions on or with
          respect to the Pledged Securities (other than Distributions
          constituting additional Pledged Securities).  All Distributions
          constituting additional Pledged Securities will be retained by the
          Agent (or if received by any Obligor shall be held by such Person in
          trust and shall be immediately delivered by such Person to the Agent
          in the original form received, endorsed in blank) and held by the
          Agent as part of the Credit Security.

                    (ii)  If an Event of Default shall have occurred, all
          Distributions on or with respect to the Pledged Securities shall be
          retained by the Agent (or if received by any Obligor shall be held by
          such Person in trust and shall be immediately delivered by it to the
          Agent in the original form received, endorsed in blank) and held by
          the Agent as part of the Credit Security or applied by the Agent to
          the payment of the Credit Obligations in accordance with Section
          10.5.6.

          (b)       Voting.
                    ------ 

                    (i)   Until an Event of Default shall occur, the respective
          Obligors shall be entitled to vote or consent or refrain from voting
          or consenting with respect to the Pledged Securities in any manner not
          inconsistent with the terms of any Credit Document, and the Agent
          will, if so requested, execute appropriate revocable proxies therefor.

                                      -78-
<PAGE>
 
               (ii)  If an Event of Default shall have occurred, if and to the
           extent that the Agent shall so notify in writing the Obligor pledging
           the Pledged Securities in question, only the Agent shall be entitled
           to vote or consent or take any other action with respect to the
           Pledged Securities (and any Obligor will, if so requested, execute or
           cause to be executed appropriate proxies therefor).

     10.5. Right to Realize upon Credit Security.  Except to the extent
           -------------------------------------                       
prohibited by applicable law that cannot be waived, this Section 10.5 shall
govern the Lenders' right to realize upon the Credit Security if any Event of
Default shall have occurred.  The provisions of this Section 10.5 are in
addition to any rights and remedies available at law or in equity and in
addition to the provisions of any other Credit Document.  In the case of a
conflict between this Section 10.5 and any other Credit Document, this Section
10.5 shall govern.

           10.5.1.   Assembly of Credit Security; Receiver.  Each of the 
                     -------------------------------------
     Obligors shall, upon the Agent's request, assemble the Credit Security and
     otherwise make it available to the Agent. The Agent may have a receiver
     appointed for all or any portion of the Obligor's assets or business which
     constitutes the Credit Security in order to manage, protect, preserve, sell
     and otherwise dispose of all or any portion of the Credit Security in
     accordance with the terms of the Credit Documents, to continue the
     operations of the Obligors and to collect all revenues and profits
     therefrom to be applied to the payment of the Credit Obligations, including
     the compensation and expenses of such receiver.

          10.5.2.    General Authority.  To the extent specified in written 
                     -----------------
     notice from the Agent to the Obligor in question, each Obligor grants the
     Agent full and exclusive power and authority, subject to the other terms
     hereof and applicable law, to take any of the following actions (for the
     sole benefit of the Agent on behalf of the Lenders and the holders from
     time to time of any Credit Obligations, but at the Obligor's expense):

          (a) To ask for, demand, take, collect, sue for and receive all
     payments in respect of any Pledged Securities which the Obligor could
     otherwise ask for, demand, take, collect, sue for and receive for its own
     use.

          (b) To extend the time of payment of any Pledged Securities and to
     make any allowance or other adjustment with respect thereto.

          (c) To settle, compromise, prosecute or defend any action or
     proceeding with respect to any Pledged Securities and to enforce all rights
     and remedies thereunder which the Obligor could otherwise enforce.

          (d) To enforce the payment of any Pledged Securities, either in the
     name of the Obligor or in its own name, and to endorse the name of the
     Obligor on all checks, drafts,

                                     -79-
<PAGE>
 
     money orders and other instruments tendered to or received in payment of
     any Credit Security.

         (e)     To notify the third party payor with respect to any Pledged
     Securities of the existence of the security interest created hereby and to
     cause all payments in respect thereof thereafter to be made directly to the
     Agent; provided, however, that whether or not the Agent shall have so
            --------  -------                                             
     notified such payor, the Obligors will at their expense render all
     reasonable assistance to the Agent in collecting such items and in
     enforcing claims thereon.

         (f)     To sell, transfer, assign or otherwise deal in or with any
     Credit Security or the proceeds thereof, as fully as any Obligor otherwise


         10.5.3.   Marshaling, etc.  Neither the Agent nor the Lenders shall be
                   ---------------                                             
     required to make any demand upon, or pursue or exhaust any of their rights
     or remedies against, any Obligor or any other guarantor, pledgor or any
     other Person with respect to the payment of the Credit Obligations or to
     pursue or exhaust any of their rights or remedies with respect to any
     collateral therefor or any direct or indirect guarantee thereof. Neither
     the Agent nor the Lenders shall be required to marshal the Credit Security
     or any guarantee of the Credit Obligations or to resort to the Credit
     Security or any such guarantee in any particular order, and all of its and
     their rights hereunder or under any other Credit Document shall be
     cumulative. To the extent it may lawfully do so, each of the Obligors
     absolutely and irrevocably waives and relinquishes the benefit and
     advantage of, and covenants not to assert against the Agent or the Lenders,
     any valuation, stay, appraisement, extension, redemption or similar laws
     now or hereafter existing which, but for this provision, might be
     applicable to the sale of any Credit Security made under the judgment,
     order or decree of any court, or privately under the power of sale
     conferred by this Agreement, or otherwise. Without limiting the generality
     of the foregoing, each of the Obligors (a) agrees that it will not invoke
     or utilize any law which might prevent, cause a delay in or otherwise
     impede the enforcement of the rights of the Agent or any Lender in the
     Credit Security, (b) waives all such laws, and (c) agrees that it will not
     invoke or raise as a defense to any enforcement by the Agent or any Lender
     of any rights and remedies relating to the Credit Security or the Credit
     Obligations any legal or contractual requirement with which the Agent or
     any Lender may have in good faith failed to comply. In addition, each of
     the Obligors waives any right to prior notice (except to the extent
     expressly required by this Agreement) or judicial hearing in connection
     with foreclosure on or disposition of any Credit Security, including any
     such right which such Obligor would otherwise have under the Constitution
     of the United States of America, any state or territory thereof or any
     other jurisdiction.

         10.5.4.   Sales of Credit Security.  All or any part of the Credit
                   ------------------------                                
     Security may be sold for cash or other value in any number of lots at
     public or private sale, without demand, advertisement or notice; provided,
                                                                      --------  
     however, that unless the Credit Security to be sold threatens to decline 
     -------      
     speedily in value or is of a type customarily sold on a recognized

                                     -80-
<PAGE>
 
market, the Agent shall give the Obligor granting the security interest in such
Credit Security ten days' prior written notice of the time and place of any
public sale, or the time after which a private sale may be made, which notice
each of the Obligors and the Lenders hereby agrees to be reasonable. At any sale
or sales of Credit Security, any Lender or any of its respective officers acting
on its behalf, or such Lender's assigns, may bid for and purchase all or any
part of the property and rights so sold, may use all or any portion of the
Credit Obligations owed to such Lender as payment for the property or rights so
purchased, and upon compliance with the terms of such sale may hold and dispose
of such property and rights without further accountability to the respective
Obligor, except for the proceeds of such sale or sales pursuant to Section
10.5.6. The Obligors acknowledge that any such sale will be made by the Agent on
an "as is" basis with disclaimers of all warranties, whether express or implied.
The respective Obligors will execute and deliver or cause to be executed and
delivered such instruments, documents, assignments, waivers, certificates and
affidavits, will supply or cause to be supplied such further information and
will take such further action as the Agent shall request in connection with any
such sale.

          10.5.5.   Sale Without Registration.  If, at any time when the Agent 
                    -------------------------
shall determine to exercise its rights hereunder to sell all or part of the
securities included in the Credit Security, the securities in question shall not
be effectively registered under the Securities Act (or other applicable law),
the Agent may, in its sole discretion, sell such securities by private or other
sale not requiring such registration in such manner and in such circumstances as
the Agent may deem necessary or advisable in order that such sale may be
effected in accordance with applicable securities laws without such registration
and the related delays, uncertainty and expense. Without limiting the generality
of the foregoing, in any event the Agent may, in its sole discretion, (a)
approach and negotiate with a single purchaser or one or more possible
purchasers to effect such sale, (b) restrict such sale to one or more purchasers
each of whom will represent and agree that such purchaser is purchasing for its
own account, for investment and not with a view to the distribution or sale of
such securities and (c) cause to be placed on certificates representing the
securities in question a legend to the effect that such securities have not been
registered under the Securities Act (or other applicable law) and may not be
disposed of in violation of the provisions thereof. Each of the Obligors agrees
that such manner of disposition is commercially reasonable, that it will upon
the Agent's request give any such purchaser access to such information regarding
the issuer of the securities in question as the Agent may reasonably request and
that the Agent and the Lenders shall not incur any responsibility for selling
all or part of the securities included in the Credit Security at any private or
other sale not requiring such registration, notwithstanding the possibility that
a substantially higher price might be realized if the sale were deferred until
after registration under the Securities Act (or other applicable law) or until
made in compliance with certain other rules or exemptions from the registration
provisions under the Securities Act (or other applicable law). Each of the
Obligors acknowledges that no adequate remedy at law exists for breach by it of
this Section 10.5.5 and that such breach would not be adequately

                                     -81-
<PAGE>
 
       compensable in damages and therefore agrees that this Section 10.5.5 may
       be specifically enforced.

              10.5.6.   Application of Proceeds.  The proceeds of all sales and
                        -----------------------                                
       collections in respect of any Credit Security or other assets of any
       Obligor, all funds collected from the Obligors and any cash contained in
       the Credit Security, the application of which is not otherwise
       specifically provided for herein, shall be applied as follows:

              First, to the payment of the costs and expenses of such sales and
       collections, the reasonable expenses of the Agent and the reasonable fees
       and expenses of its special counsel;

              Second, any surplus then remaining to the payment of the Credit
       Obligations (other than in respect of Interest Rate Protection
       Agreements) in such order and manner as the Agent may in its sole
       discretion determine; provided, however, that any such payment of Credit
                             --------  -------   
       Obligations owed to all Lenders shall be pro rata in accordance with the
       respective Percentage Interests of the Lenders;

              Third, any surplus then remaining to the payment of the Credit
       Obligations in respect of Interest Rate Protection Agreements with any
       Lender in such order and manner as the Agent may in its sole discretion
       determine; and

              Fourth, any surplus then remaining shall be paid to the Obligors,
       subject, however, to the rights of the holder of any then existing Lien
       of which the Agent has actual notice.

       10.6.  Custody of Credit Security.  Except as provided by applicable law 
              --------------------------  
that cannot be waived, the Agent will have no duty as to the custody and
protection of the Credit Security, the collection of any part thereof or of any
income thereon or the preservation or exercise of any rights pertaining thereto,
including rights against prior parties, except for the use of reasonable care in
the custody and physical preservation of any Credit Security in its possession.
The Lenders will not be liable or responsible for any loss or damage to any
Credit Security, or for any diminution in the value thereof, by reason of the
act or omission of any agent selected by the Agent acting in good faith.

11.    Expenses; Indemnity.
       ------------------- 

       11.1.  Expenses.  Whether or not the transactions contemplated hereby 
              --------
shall be consummated, the Company will pay:

              (a)   all reasonable expenses of the Agent (including the out-of-
       pocket expenses related to forming the group of Lenders and reasonable
       fees and disbursements of the counsel to the Agent) in connection with
       the preparation and duplication of this Agreement, each other Credit
       Document, any environmental audit or review reports, examinations by,

                                     -82-
<PAGE>
 
     and reports of, the Agent's commercial financial examiners, the
     transactions contemplated hereby and thereby and amendments, waivers,
     consents and other operations hereunder and thereunder;

            (b)  all recording and filing fees and transfer and documentary
     stamp and similar taxes at any time payable in respect of this Agreement,
     any other Credit Document, any Credit Security or the incurrence of the
     Credit Obligations; and

            (c)  all other reasonable expenses incurred by the Lenders or the
     holder of any Credit Obligation in connection with the enforcement of any
     rights hereunder or under any other Credit Document, including costs of
     collection and reasonable attorneys' fees (including a reasonable allowance

Loan and the Letters of Credit, and the related Commitments, shall be computed
based on the maximum principal amount for each Lender as set forth in the
Register, as from time to time in effect.  The current Percentage Interests are
set forth in Exhibit 12.1, which may be updated by the Agent from time to time
to conform to the Register.

Documents on the terms set forth herein. In acting hereunder, the Agent is
acting for the account of BankBoston to the extent of its Percentage Interest
and for the account of each other Lender to the extent of the Lenders'
respective Percentage Interests, and all action in connection with the
enforcement of, or the exercise of any remedies (other than the Lenders' rights
of set-off as provided in Section 8.2.4 or in any Credit Document) in respect of
the Credit Obligations and Credit Documents shall be taken by the Agent.

    12.3.  Company to Pay Agent, etc.  The Company and each Guarantor shall be
           -------------------------                                          
fully protected in making all payments in respect of the Credit Obligations to
the Agent, in relying upon consents, modifications and amendments executed by
the Agent purportedly on the Lenders' behalf, and in dealing with the Agent as
herein provided.  The Agent may charge the accounts of the Company, on the dates

principal of and interest on the Loan, any amounts paid by the Letter of Credit
Issuers to third parties under Letters of Credit or drafts presented thereunder,

to the Agent in immediately available funds such Lender's Percentage Interest in
the portion of the Loan advanced on such Closing Date prior to 3:30 p.m. (Boston
time). If such funds are not received at such time, but all applicable

and requests the Agent to advance for the Lender's account, pursuant to the
terms hereof, the Lender's respective Percentage Interest in such portion of the
Loan and agrees to reimburse the Agent in immediately available funds for the
amount thereof prior to 4:30 p.m. (Boston time) on the day any portion of the
Loan is advanced hereunder; provided, however, that the Agent is not authorized
                            --------  -------

notified the Agent in writing

                                     -84-
<PAGE>
 
that such Lender will not be performing its obligations to make further advances
hereunder; and provided, further, that the Agent shall be under no obligation
               --------  -------          
to make any such advance.

          12.4.2.   Letters of Credit.  Each of the Lenders authorizes and

requests each Letter of Credit Issuer to issue the Letters of Credit provided
for in Section 2.4 and to grant each Lender a participation in each of such
Letters of Credit in an amount equal to its Percentage Interest in the amount of
each such Letter of Credit. Promptly upon the request of the Letter of Credit
Issuer, each Lender shall reimburse the Letter of Credit Issuer in immediately
available funds for such Lender's Percentage Interest in the amount of all
obligations to third parties incurred by the Letter of Credit Issuer in respect
of each Letter of Credit and each draft accepted under a Letter of Credit to the
extent not reimbursed by the Company. The Letter of Credit Issuer will notify
each Lender of the issuance of any Letter of Credit, the amount and date of
payment of any draft drawn or accepted under a Letter of Credit and whether in
connection with the payment of any such draft the amount thereof was added to
the Revolving Loan or was reimbursed by the Company.

          12.4.3.   Agent to Allocate Payments, etc.  All payments of principal 
                    --------------------------------

parties under Letters of Credit or drafts presented thereunder, facility fees,
Letter of Credit fees and other fees under this Agreement shall, as a matter of
convenience, be made by the Company and the Guarantors to the Agent in
immediately available funds. The share of each Lender shall be credited to such
Lender by the Agent in immediately available funds in such manner that the
principal amount of the Credit Obligations to be paid shall be paid
proportionately in accordance with the Lenders' respective Percentage Interests
in such Credit Obligations, except as otherwise provided in this Agreement.
Under no circumstances shall any Lender be required to produce or present its
Notes as evidence of its interests in the Credit Obligations in any action or
proceeding relating to the Credit Obligations.

          12.4.4.   Delinquent Lenders; Nonperforming Lenders.  In the event 
                    -----------------------------------------  
that any Lender fails to reimburse the Agent pursuant to Section 12.4.1 for the
Percentage Interest of such lender (a "Delinquent Lender") in any credit
                                       -----------------                
advanced by the Agent pursuant hereto, overdue amounts (the "Delinquent
                                                             ----------
Payment") due from the Delinquent Lender to the Agent shall bear interest,
payable by the Delinquent Lender on demand, at a per annum rate equal to (a) the
Federal Funds Rate for the first three days overdue and (b) the sum of 2% plus
                                                                          ----
the Federal Funds Rate for any longer period.  Such interest shall be payable to
the Agent for its own account for the period commencing on the date of the
Delinquent Payment and ending on the date the Delinquent Lender reimburses the
Agent on account of the Delinquent Payment (to the extent not paid by the
Company as provided below) and the accrued interest thereon (the "Delinquency
                                                                  -----------
Period"), whether pursuant to the assignments referred to below or otherwise.
------                                                                        
Upon notice by the Agent, the Company will pay to the Agent the principal (but
not the interest) portion of the Delinquent Payment.

                                     -85-
<PAGE>
 
      During the Delinquency Period, in order to make reimbursements for the
      Delinquent Payment and accrued interest thereon, the Delinquent Lender
      shall be deemed to have assigned to the Agent all interest, facility fees
      and other payments made by the Company under Section 3 that would have
      thereafter otherwise been payable under the Credit Documents to the
      Delinquent Lender. During any other period in which any Lender is not
      performing its obligations to extend credit under Section 2 (a
      "Nonperforming Lender"), the Nonperforming Lender shall be deemed to have
       --------------------                                                    
      assigned to each Lender that is not a Nonperforming Lender (a "Performing
                                                                     ----------
      Lender") all principal and other payments made by the Company under 
      ------
      Section 4 that would have thereafter otherwise been payable under the
      Credit Documents to the Nonperforming Lender. The Agent shall credit a
      portion of such payments to each Performing Lender in an amount equal to
      the Percentage Interest of such Performing Lender in an amount equal to
      the Percentage Interest of such Performing Lender divided by one minus the
                                                                       ----- 
      Percentage Interest of the Nonperforming Lender until the respective
      portions of the Loan owed to all the Lenders are the same as the
      Percentage Interests of the Lenders immediately prior to the failure of
      the Nonperforming Lender to perform its obligations under Section 2. The
      foregoing provisions shall be in addition to any other remedies the Agent,
      the Performing Lenders or the Company may have under law or equity against
      the Delinquent Lender as a result of the Delinquent Payment or against the
      Nonperforming Lender as a result of its failure to perform its obligations
      under Section 2.

      12.5.  Sharing of Payments, etc.  Each Lender agrees that (a) if by
             -------------------------                                   
exercising any right of set-off or counterclaim or otherwise, it shall receive
payment of (i) a proportion of the aggregate amount due with respect to its
Percentage Interest in the Loan and Letter of Credit Exposure which is greater
than (ii) the proportion received by any other Lender in respect of the
aggregate amount due with respect to such other Lender's Percentage Interest in
the Loan and Letter of Credit Exposure and (b) if such inequality shall continue
for more than 10 days, the Lender receiving such proportionately greater payment
shall purchase participations in the Percentage Interests in the Loan and Letter
of Credit Exposure held by the other Lenders, and such other adjustments shall
be made from time to time (including rescission of such purchases of
participations in the event the unequal payment originally received is recovered
from such Lender through bankruptcy proceedings or otherwise), as may be
required so that all such payments of principal and interest with respect to the
Loan and Letter of Credit Exposure held by the Lenders shall be shared by the
Lenders pro rata in accordance with their respective Percentage Interests;
provided, however, that this Section 12.5 shall not impair the right of any
--------  -------                                                          
Lender to exercise any right of set-off or counterclaim it may have and to apply
the amount subject to such exercise to the payment of Indebtedness of any
Obligor other than such Obligor's Indebtedness with respect to the Loan and
Letter of Credit Exposure; provided, further, that such application may be
                           --------  -------                              
affected by Section 4.05 of the Intercreditor Agreement.  Each Lender that
grants a participation in the Credit Obligations to a Credit Participant shall
require as a condition to the granting of such participation that such Credit
Participant agree to share payments received in respect of the Credit
Obligations as provided in this Section 12.5.  The provisions of this Section
12.5 are for the sole and exclusive benefit of the Lenders and no failure of any
Lender to comply

with the terms hereof shall be available to any Obligor as a defense to the
payment of the Credit Obligations.

     12.6.  Amendments, Consents, Waivers, etc.  Except as otherwise set forth
            ----------------------------------

other Credit Document, including giving its written consent to any modification
of or amendment to and waiving in writing compliance with any covenant or
condition in this Agreement or any other Credit Document (other than an Interest
Rate Protection Agreement) or any Default or Event of Default, all of which
actions shall be binding upon all of the Lenders; provided, however, that:
                                                  --------  -------

     respect to, waiver of compliance with or waiver of a Default under, any of
     the Credit Documents (other than an Interest Rate Protection Agreement)
     shall be made.

            (b) Without the written consent of such Lenders as own 100% of the
     Percentage Interests (other than Delinquent Lenders during the existence of
     a Delinquency Period so long as such Delinquent Lender is treated the same
     as the other Lenders with respect to any actions enumerated below):

                (i)   No reduction shall be made in (A) the amount of principal
          of the Loan or reimbursement obligations for payments made under
          Letters of Credit, (B) the interest rate on the Loan or (C) the Letter
          of Credit fees (except those owed solely to the Letter of Credit
          Issuer, which may be reduced by agreement solely between the Company
          and the Letter of Credit Issuer) or facility fees.

                (ii)  No change shall be made in the stated time of payment of
          all or any portion of the Loan or interest thereon or reimbursement of
          payments made under Letters of Credit or fees relating to any of the
          foregoing payable to all of the Lenders and no waiver shall be made of
          any Default under Section 8.1.1.

                (iii) No increase shall be made in the amount, or extension of
          the term, of the Commitments beyond that provided for under Section 2.

                (iv)  No alteration shall be made of the Lenders' rights of set-
          off contained in Section 8.2.4.

                (v)   No release of any Credit Security or of any Guarantor
          shall be made (except that the Agent may release particular items of
          Credit Security or particular Guarantors in dispositions permitted by
          Section 6.11 and may release all Credit Security pursuant to Section
          18 upon payment in full of the Credit Obligations and termination of
          the Commitments without the written consent of the Lenders).

the Lenders and the Company and upon the appointment by the Required Lenders of
a successor Agent satisfactory to the Company. If no successor Agent shall have
been so appointed and shall have accepted such appointment within 45 days after
the retiring Agent's giving of such notice of resignation, then the retiring

withheld, appoint a successor Agent which shall be a bank or a trust company

sentence may be removed upon the written request of the Required Lenders, which
request shall also appoint a successor Agent satisfactory to the Company.  Upon
the appointment of a new Agent hereunder, the term "Agent" shall for all
purposes of this Agreement thereafter mean such successor.  After any retiring
Agent's resignation hereunder as Agent, or the removal hereunder of any
successor Agent, the provisions of this Agreement shall continue to inure to the
benefit of such Agent as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement.

       12.9.  Rights as a Lender.  With respect to any credit extended by it
              ------------------                                            
hereunder, BankBoston shall have the same rights, obligations and powers
hereunder as any other Lender and may exercise such rights and powers as though
it were not the Agent, and unless the context otherwise specifies, BankBoston
shall be treated in its individual capacity as though it were not the Agent
hereunder. Without limiting the generality of the foregoing, the Percentage
Interest of BankBoston shall be included in any computations of Percentage
Interests. BankBoston and its Affiliates may accept deposits from, lend money
to, act as trustee for and generally engage in any kind of banking or trust
business with the Company, any of its Subsidiaries or any Affiliate of any of
them and any Person who may do business with or own an equity interest in the
Company, any of its Subsidiaries or any Affiliate of any of them, all as if
BankBoston were not the Agent and without any duty to account therefor to the
other Lenders.

       12.10. Independent Credit Decision.  Each of the Lenders acknowledges 
              ---------------------------
that it has independently and without reliance upon the Agent, based on the
financial statements and other documents referred to in Section 7.2, on the
other representations and warranties contained herein and on such other
information with respect to the Company and its Subsidiaries as such Lender
deemed appropriate, made such Lender's own credit analysis and decision to enter
into this Agreement and to make the extensions of credit provided for hereunder.
Each Lender represents to the Agent that such Lender will continue to make its
own independent credit and other decisions in taking or not taking action under
this Agreement or any other Credit Document. Each Lender expressly acknowledges
that neither the Agent nor any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates has made any representations or warranties to
such Lender, and no act by the Agent taken under this Agreement or any other
Credit Document, including any review of the affairs of the Company and its
Subsidiaries, shall be deemed to constitute any representation or warranty by
the Agent. Except for notices, reports and other documents expressly required to
be furnished to each Lender by the Agent under this Agreement or any other
Credit Document, the Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, property, condition, financial or otherwise, or creditworthiness of
the Company or any Subsidiary which may come into the possession of the Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates.

       12.11. Indemnification.  The holders of the Credit Obligations shall
              ---------------                                              
indemnify the Agent and its officers, directors, employees and agents (to the
extent not reimbursed by the Obligors and without limiting the obligation of any
of the Obligors to do so), pro rata in accordance with their

                                     -90-
<PAGE>
 
respective Percentage Interests, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time be
imposed on, incurred by or asserted against the Agent or such Persons relating
to or arising out of this Agreement, any other Credit Document, the transactions
contemplated hereby or thereby, or any action taken or omitted by the Agent in
connection with any of the foregoing; provided, however, that the foregoing
                                      --------  -------               
shall not extend to actions or omissions which are taken by the Agent with gross
negligence or willful misconduct.

13.  Successors and Assigns; Lender Assignments and Participations.  Any
     -------------------------------------------------------------      
reference in this Agreement to any of the parties hereto shall be deemed to
include the successors and assigns of such party, and all covenants and
agreements by or on behalf of the Company, the Guarantors, the Agent or the
Lenders that are contained in this Agreement or any other Credit Documents shall
bind and inure to the benefit of their respective successors and assigns;
provided, however, that (a) the Company and its Subsidiaries may not assign
--------  -------                                                          
their rights or obligations under this Agreement except for mergers or
liquidations permitted by Section 6.11, and (b) the Lenders shall be not
entitled to assign their respective Percentage Interests in the Loan hereunder
except as set forth below in this Section 13.

     13.1.  Assignments by Lenders.
            ---------------------- 

            13.1.1.   Assignees and Assignment Procedures.  Each Lender may (a)
                      -----------------------------------                      
     without the consent of the Agent or the Company if the proposed assignee is
     already a Lender hereunder or a Wholly Owned Subsidiary of the same
     corporate parent of which the assigning Lender is a Subsidiary, or (b)
     otherwise with the consents of the Agent and (so long as no Event of
     Default exists) the Company (which consents will not be unreasonably
     withheld), in compliance with applicable laws in connection with such
     assignment, assign to one or more commercial banks or other financial
     institutions (each, an "Assignee") all or a portion of its interests, 
                             --------           
     rights and obligations under this Agreement and the other Credit Documents,
     including all or a portion, which need not be pro rata between the Loan and
     the Letter of Credit Exposure, of its Commitment, the portion of the Loan
     and Letter of Credit Exposure at the time owing to it and the Notes held by
     it, but excluding its rights and obligations as a Letter of Credit Issuer;
     provided, however, that:
     --------  -------       

                (i)   the aggregate amount of the Commitment of the assigning
          Lender subject to each such assignment to any Assignee other than
          another Lender (determined as of the date the Assignment and
          Acceptance with respect to such assignment is delivered to the Agent)
          shall be not less than $5,000,000 and in increments of $1,000,000; and

                (ii)   the parties to each such assignment shall execute and
          deliver to the Agent an Assignment and Acceptance (the "Assignment and
                                                                  --------------
          Acceptance") substantially in the form of Exhibit 13.1.1, together
          ----------                                                        
          with the Note subject to such

                                     -91-
<PAGE>
 
          assignment and a processing and
          recordation fee of $3,000 payable to the Agent by the assigning
          Lender.

Upon acceptance and recording pursuant to Section 13.1.4, from and after the
effective date specified in each Assignment and Acceptance (which effective date
shall be at least five Banking Days after the execution thereof unless waived by
the Agent):

          (1)  the Assignee shall be a party hereto and, to the extent provided
               in such Assignment and Acceptance, have the rights and
               obligations of a Lender under this Agreement and

          (2)  the assigning Lender shall, to the extent provided in such
               assignment, be released from its obligations under this Agreement
               (and, in the case of an Assignment and Acceptance covering all or
               the remaining portion of an assigning Lender's rights and
               obligations under this Agreement, such Lender shall cease to be a
               party hereto but shall continue to be entitled to the benefits of
               Sections 3.2.4, 3.5, 3.6, 3.7, 3.8 and 11, as well as to any fees
               accrued for its account hereunder and not yet paid).

          13.1.2. Terms of Assignment and Acceptance.  By executing and 
                  ----------------------------------    
delivering an Assignment and Acceptance, the assigning Lender and Assignee shall
be deemed to confirm to and agree with each other and the other parties hereto
as follows:

          (a) other than the representation and warranty that it is the legal
and beneficial owner of the interest being assigned thereby free and clear of
any adverse claim, such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with this Agreement or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement, any other Credit Document or any other instrument or document
furnished pursuant hereto;

          (b) such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition of the Company
and its Subsidiaries or the performance or observance by the Company or any of
its Subsidiaries of any of its obligations under this Agreement, any other
Credit Document or any other instrument or document furnished pursuant hereto;

          (c) such Assignee confirms that it has received a copy of this
Agreement, together with copies of the most recent financial statements
delivered pursuant to Section 7.2 or Section 6.4 and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance;


                                     -92-
<PAGE>
 
          (d) such Assignee will independently and without reliance upon the
Agent, such assigning Lender or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement;

          (e) such Assignee appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
as are delegated to the Agent by the terms hereof, together with such powers as
are reasonably incidental thereto; and

          (f) such Assignee agrees that it will perform in accordance with the
terms of this Agreement all the obligations which are required to be performed
by it as a Lender.

          13.1.3.   Register.  The Agent shall maintain at the Boston Office a
                    --------                                                  
register (the "Register") for the recordation of (a) the names and addresses of
               --------                                                        
the Lenders and the Assignees which assume rights and obligations pursuant to an
assignment under Section 13.1.1, (b) the Percentage Interest of each such Lender
as set forth in Section 12.1 and (c) the amount of the Loan and Letter of Credit
Exposure owing to each Lender from time to time.  The entries in the Register
shall be conclusive, in the absence of demonstrable error, and the Company, the
Agent and the Lenders may treat each Person whose name is registered therein for
all purposes as a party to this Agreement.  The Register shall be available for
inspection by the Company or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

          13.1.4.   Acceptance of Assignment and Assumption.  Upon its receipt 
                    ---------------------------------------           
of a completed Assignment and Acceptance executed by an assigning Lender and an
Assignee together with the Note subject to such assignment, and the processing
and recordation fee referred to in Section 13.1.1, the Agent shall (a) accept
such Assignment and Acceptance, (b) record the information contained therein in
the Register and (c) give prompt notice thereof to the Company. Within five
Banking Days after receipt of notice, the Company, at its own expense, shall
execute and deliver to the Agent, in exchange for the surrendered Note, a new
Note to the order of such Assignee in a principal amount equal to the applicable
Commitment and Loan assumed by it pursuant to such Assignment and Acceptance
and, if the assigning Lender has retained a Commitment and Loan, a new Note to
the order of such assigning Lender in a principal amount equal to the applicable
Commitment and Loan retained by it. Such new Note shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Note, and shall be dated the date of the surrendered Note which it replaces.

          13.1.5.   Federal Reserve Bank.  Notwithstanding the foregoing 
                    -------------------- 
provisions of this Section 13, any Lender may at any time pledge or assign all
or any portion of such Lender's rights under this Agreement and the other Credit
Documents to a Federal Reserve

                                      -93-
<PAGE>
 
     Bank; provided, however, that no such pledge or assignment shall
           --------  ------- 
     release such Lender from such Lender's obligations hereunder or under any
     other Credit Document.

          13.1.6. Further Assurances.  The Company and its Subsidiaries shall 
                  ------------------ 
     sign such documents and take such other actions from time to time 
     reasonably requested by an Assignee to enable it to share in the benefits 
     of the rights created by the Credit Documents.

     13.2.  Credit Participants.  Each Lender may, (a) without the consent of 
            -------------------
the Company or the Agent if the proposed participant is already a Lender or a
Credit Participant hereunder or a Wholly Owned Subsidiary of the same corporate
parent of which the Lender is a Subsidiary or (b) otherwise with the consents of
the Agent and (so long as no Event of Default exists) the Company (which
consents will not be unreasonably withheld), in compliance with applicable laws
in connection with such participation, sell to one or more commercial banks or
other financial institutions (each a "Credit Participant") participations in all
                                      ------------------                        
or a portion of its interests, rights and obligations under this Agreement and
the other Credit Documents (including all or a portion of its Commitment, the
Loan and Letter of Credit Exposure owing to it and the Note held by it);
provided, however, that:
--------  -------       

          (a)    such Lender's obligations under this Agreement shall remain
                 unchanged;

          (b)    such Lender shall remain solely responsible to the other
     parties hereto for the performance of such obligations;

          (c)    the Credit Participant shall be entitled to the benefit of the
     cost protection provisions contained in Sections 3.2.4, 3.5, 3.6, 3.7, 3.8
     and 11, but shall not be entitled to receive any greater payment 
     thereunder than the selling Lender would have been entitled to receive 
     with respect to the interest so sold if such interest had not been sold; 
     and 
          (d) the Company, the Agent 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, and such Lender shall retain
     the sole right as one of the Lenders to vote with respect to the
     enforcement of the obligations of the Company relating to the Loan and
     Letter of Credit Exposure and the approval of any amendment, modification
     or waiver of any provision of this Agreement (other than amendments,
     modifications, consents or waivers described in clause (b) of the proviso
     to Section 12.6).

Each Obligor agrees, to the fullest extent permitted by applicable law, that any
Credit Participant and any Lender purchasing a participation from another Lender
pursuant to Section 12.5 may exercise all rights of payment (including the right
of set-off), with respect to its participation as fully as if such Credit
Participant or such Lender were the direct creditor of the Obligors and a Lender
hereunder in the amount of such participation.

     13.3.  Replacement of Lender.  In the event that any Lender or, to the 
            ---------------------
extent applicable, any Credit Participant (the "Affected Lender"):
                                                ---------------   

            (a) fails to perform its obligations to fund any portion of the Loan
     or to issue any Letter of Credit on any Closing Date when required to do so
     by the terms of the Credit Documents;
   
            (b) demands payment under the Reserve provisions of Section 3.5, the
     Tax provisions of Section 3.6, the capital adequacy provisions of Section
     3.7 or the regulatory change provisions in Section 3.8 in an amount the
     Company deems materially in excess of the amounts with respect thereto
     demanded by the other Lenders; or

            (c) refuses to consent to a proposed amendment, modification, waiver
     or other action requiring consent of the holders of 100% of the Percentage
     Interests under Section 12.6(b) that is consented to by the other Lenders;

then, so long as no Event of Default exists, the Company shall have the right to
seek a replacement lender which is reasonably satisfactory to the Agent (the
"Replacement Lender").  The Replacement Lender shall purchase the interests of
-------------------                                                           
the Affected Lender in the Loan, Letters of Credit and its Commitment and shall
assume the obligations of the Affected Lender hereunder and under the other
Credit Documents upon execution by the Replacement Lender of an Assignment and
Acceptance and the tender by it to the Affected Lender of a purchase price
agreed between it and the Affected Lender (or, if they are unable to agree, a
purchase price in the amount of the Affected Lender's Percentage Interest in the
Loan and Letter of Credit Exposure, or appropriate credit support for contingent
amounts included therein, and all other outstanding Credit Obligations then owed
to the Affected Lender).  Such assignment by the Affected Lender shall be deemed
an early termination of any Eurodollar Pricing Option to the extent of the
Affected Lender's portion thereof, and the Company will pay to the Affected
Lender any resulting amounts due under Section 3.2.4.  Upon consummation of such
assignment, the Replacement Lender shall become party to this Agreement as a
signatory hereto and shall have all the rights and obligations of the Affected
Lender under this Agreement and the other Credit Documents with a Percentage
Interest equal to the Percentage Interest of the Affected Lender, the Affected
Lender shall be released from its obligations hereunder and under the other
Credit Documents, and no further consent or action by any party shall be
required.  Upon the consummation of such assignment, the Company, the Agent and
the Affected Lender shall make appropriate arrangements so that a new Revolving
Note is issued to the Replacement Lender if it has acquired a portion of the
Revolving Loan.  The Company and the Guarantors shall sign such documents and
take such other actions reasonably requested by the Replacement Lender to enable
it to share in the benefits of the rights created by the Credit Documents.
Until the consummation of an assignment in accordance with the foregoing
provisions of this Section 13.3, the Company shall continue to pay to the
Affected Lender any Credit Obligations as they become due and payable.

                                     -95-

14.  Confidentiality.  Each Lender will make no disclosure of confidential
     ---------------                                                      
information furnished to it directly or indirectly by the Company or any of its
Subsidiaries unless such information shall have become public, except:

          (a) in connection with operations under or the enforcement of this
       Agreement or any other Credit Document;

          (b) pursuant to any statutory or regulatory requirement or any
       mandatory court order, subpoena or other legal process;

          (c) to any parent or corporate Affiliate of such Lender or to any
       Credit Participant, proposed Credit Participant or proposed Assignee;
                                                                          
       provided, however, that any such Person shall agree to comply with the
       --------  -------                                                     
       restrictions set forth in this Section 14 with respect to such 
       information;

          (d) to its independent counsel, auditors and other professional
       advisors with an instruction to such Person to keep such information
       confidential; and

          (e) with the prior written consent of the Company, to any other
       Person.

  15.  Foreign Lenders.  If any Lender is not incorporated or organized under
       ---------------                                                       
the laws of the United States of America or a state thereof, such Lender shall
deliver to the Company and the Agent the following:

          (a) Two duly completed copies of United States Internal Revenue
     Service Form 1001 or 4224 or successor form, as the case may be, certifying
     in each case that such Person is entitled to receive payments under this
     Agreement, the Notes and reimbursement obligations under Letters of Credit
     payable to it, without deduction or withholding of any United States
     federal income taxes; and

          (b) A duly completed Internal Revenue Service Form W-8 or W-9 or
     successor form, as the case may be, to establish an exemption from United
     States backup withholding tax.

     Each such Lender that delivers to the Company and the Agent a Form 1001 or
4224 and Form W-8 or W-9 pursuant to this Section 15 further undertakes to
deliver to the Company and the Agent two further copies of Form 1001 or 4224 and
Form W-8 or W-9, or successor applicable form, or other manner of certification,
as the case may be, on or before the date that any such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form previously delivered by it to the Company and the Agent.  Such Forms
1001 or 4224 shall certify that such Lender is entitled to receive payments
under this Agreement without deduction or withholding of any United States
federal income taxes.  The foregoing documents need not be delivered in the
event any change in treaty, law or regulation or official

                                     -96-
<PAGE>
 
interpretation thereof has occurred which renders all such forms inapplicable or
which would prevent such Lender from delivering any such form with respect to
it, or such Lender advises the Company that it is not capable of receiving
payments without any deduction or withholding of United States federal income
tax and, in the case of a Form W-8 or W-9, establishing an exemption from United
States backup withholding tax. Until such time as the Company and the Agent have
received such forms indicating that payments hereunder are not subject to United
States withholding tax or are subject to such tax at a rate reduced by an
applicable tax treaty, the Company shall withhold taxes from such payments at
the applicable statutory rate without regard to Section 3.6.

16.  Notices.  Except as otherwise specified in this Agreement, any notice
     -------                                                              
required to be given pursuant to this Agreement shall be given in writing.  Any
notice, consent, approval, demand or other communication in connection with this
Agreement shall be deemed to be given if given in writing (including telex,
telecopy or similar teletransmission) addressed as provided below (or to the
addressee at such other address as the addressee shall have specified by notice
actually received by the addressor), and if actually delivered in fully legible
form to such address (evidenced in the case of a telex, telecopy or similar
teletransmission by receipt of the correct answerback).

     If to the Company or any of its Subsidiaries, to it at its address set
forth in Exhibit 7.1 (as supplemented pursuant to Sections 6.4.1 and 6.4.2), to
the attention of the chief financial officer.

     If to any Lender or the Agent, to it at its address set forth on the
signature pages of this Agreement or in the Register, with a copy to the Agent.

17.  Course of Dealing; Amendments and Waivers.  No course of dealing between
     -----------------------------------------                               
any Lender or the Agent, on one hand, and the Company or any other Obligor, on
the other hand, shall operate as a waiver of any of the Lenders' or the Agent's
rights under this Agreement or any other Credit Document or with respect to the
Credit Obligations.  Each of the Company and the Guarantors acknowledges that if
the Lenders or the Agent, without being required to do so by this Agreement or
any other Credit Document, give any notice or information to, or obtain any
consent from, the Company or any other Obligor, the Lenders and the Agent shall
not by implication have amended, waived or modified any provision of this
Agreement or any other Credit Document, or created any duty to give any such
notice or information or to obtain any such consent on any future occasion.  No
delay or omission on the part of any Lender of the Agent in exercising any right
under this Agreement or any other Credit Document or with respect to the Credit
Obligations shall operate as a waiver of such right or any other right hereunder
or thereunder.  A waiver on any one occasion shall not be construed as a bar to
or waiver of any right or remedy on any future occasion.  No waiver, consent or
amendment with respect to this Agreement or any other Credit Document shall be
binding unless it is in writing and signed by the Agent or the Required Lenders.

18.  Defeasance.  When all Credit Obligations have been paid and all Letters
     ----------
