     THE REVOLVING CREDIT FACILITIES.

     Commitment to Lend.

     Subject to the terms and conditions set forth in this Agreement, each of
the Banks severally agrees to lend to the Borrowers and the Borrowers may
borrow, repay, and reborrow from time to time between the Closing Date and the
Maturity Date, upon notice by the Borrowers to the Agent given in accordance
with 2.4, such Bank's Commitment Percentage of sums as are requested by the
Borrowers provided that the sum of the outstanding principal amount of the Loans
(giving effect to the requested Loan) plus the Maximum Drawing Amount shall not
exceed a maximum aggregate amount outstanding of $150,000,000, as such amount
may be reduced or increased pursuant to 2.2 hereof (the "Total Commitment").
Each request for a Loan or Letter of Credit hereunder shall constitute a
representation and warranty by the Borrowers that the conditions set forth in 9
and 10, as the case may be, have been satisfied on the date of such request. Any
unpaid Reimbursement Obligation with respect to any Letter of Credit shall be a
Base Rate Loan hereunder.
<PAGE>
 
     Reduction of Revolving Credit Commitment; Increase of Revolving Credit
Commitment

     (a) The Borrowers shall have the right at any time and from time to time
upon three (3) Business Day's prior written notice to the Agent to reduce by
$10,000,000 or greater amount or terminate entirely the Total Commitment,
whereupon the Commitment of each Bank shall be reduced pro rata in accordance
with such Bank's Commitment Percentage of the amount specified in such notice
or, as the case may be, terminated. The Agent will notify the Banks promptly
after receiving any notice delivered by the Borrowers pursuant to this 2.2.
Notwithstanding the foregoing, at no time may the Total Commitment be reduced to
an amount less than the sum of (i) the Maximum Drawing Amount and (ii) all Loans
then outstanding.

     (b) No reduction or termination of the Total Commitment once made may be
revoked; the portion of the Total Commitment reduced or terminated may not be
reinstated; and amounts in respect of such reduced or terminated portion may not
be reborrowed.

     (c) Unless a Default or Event of Default has occurred and is continuing,
the Borrowers may request that the Total Commitment be increased to $200,000,000
hereunder, subject to the approval of the Agent, provided, however, that (i) any
Bank which is a party to this Agreement prior to such increase may elect to fund
its pro rata share of the increase, thereby increasing its Commitment hereunder,
but no Bank shall be required to do so, (ii) in the event that it becomes
necessary to include a new Bank to provide additional funding under this 2.2,
such new Bank must be reasonably acceptable to the Agent, and (iii) the Banks'
Commitment Percentages shall be correspondingly adjusted and Notes issued or
amended and such other changes shall be made to the Loan Documents, as
necessary, to reflect any such increase in the Total Commitment.
<PAGE>
 
     The Notes.

     The Loans shall be evidenced by promissory notes of the Borrowers in
substantially the form of Exhibit A hereto (each, a "Note"), dated as of the
Closing Date and completed with appropriate insertions. One Note shall be
payable to the order of each Bank in an amount equal to such Bank's Commitment
Percentage of the Total Commitment, and representing the obligation of the
Borrowers to pay such Bank such principal amounts or, if less, the outstanding
principal amount of all Loans made by such Bank, plus interest accrued thereon,
as set forth below. The Borrowers irrevocably authorize each Bank to make or
cause to be made, in connection with a Drawdown Date of any Loan or at the time
of receipt of any payment of principal on such Bank's Note, an appropriate
notation on such Bank's records reflecting the making of the Loan or the receipt
of such payment (as the case may be) and may, prior to any transfer of its Note,
endorse on the reverse side thereof the outstanding principal amount of Loans
evidenced thereby. The outstanding amount of the Loans set forth on such Bank's
record shall be prima facie evidence of the principal amount thereof owing and
unpaid to such Bank, but the failure to record, or any error in so recording,
any such amount shall not limit or otherwise affect the obligations of the
Borrowers hereunder or under the Notes to make payments of principal of or
interest on any Note when due.

     Requests for Loans.

     The Parent as agent for the Borrowers shall give to the Agent written
notice in the form of Exhibit B hereto (or telephonic notice confirmed in
writing or a telecopy in the form of Exhibit B hereto) of each Loan requested
hereunder (a "Loan and Letter of Credit Request") not later than (a) 11:00 a.m.
(Boston time) one Business Day prior to the Drawdown Date of any Base Rate Loan,
or (b) 12:00 noon (Boston time) three (3) Eurodollar Business Days prior to the
Drawdown Date of any Eurodollar Loan. Each Loan requested shall be in a minimum
amount of $1,000,000. Each such request shall specify the principal amount of
the Loan requested and shall reflect the Maximum Drawing Amount of all Letters
of Credit and Loans outstanding. Requests for Loans made hereunder shall be
irrevocable and binding on the Borrowers, and shall obligate the Borrowers to
accept the Loan requested from the Banks on the proposed Drawdown Date. Each of
the representations and warranties made by or on behalf of the Borrowers to the
Banks or the Agent in this Agreement or any other Loan Document shall be true
and correct in all material respects when made and shall, for all purposes of
this Agreement, be deemed to be repeated on and as of the date of the submission
of a Loan and Letter of Credit Request and on and as of the Drawdown Date of
such Loan or the date of issuance of such Letter of Credit (except to the extent
(i) of changes resulting from transactions contemplated or permitted by this
Agreement and the other Loan Documents, (ii) of changes occurring in the
ordinary course of business that singly or in the aggregate are not materially
adverse to the business, assets or financial condition of any Borrower or the
Borrowers taken as a whole, (iii) of changes disclosed to the Banks in writing
and accepted by the Banks, or (iv) that such representations and warranties
expressly relate only to an earlier date). The Agent shall promptly notify each
Bank of each Loan and Letter of Credit Request received by the Agent.

     Funds for Loans.

     (a) Not later than 1:00 p.m. (Boston time) on the proposed Drawdown Date of
any Loan, each of the Banks will make available to the Agent, at its Head
Office, in immediately available funds, the amount of such Bank's Commitment
Percentage of the amount of the requested Loan. Upon receipt from each Bank of
such amount, and upon receipt of the documents required by 9 or 10, as the case
may be, and the satisfaction of the other conditions set forth therein, to the
extent applicable, the Agent will make available to the Borrowers the aggregate
amount of such Loans made available to the Agent by the Banks. The failure or
refusal of any Bank to make available to the Agent at the aforesaid time and
place on any Drawdown Date the amount of its Commitment Percentage of the
requested Loan shall not relieve any other Bank from its several obligations
hereunder to make available to the Agent the amount of such Bank's Commitment
Percentage of any requested Loan.
<PAGE>
 
     (b) The Agent may (unless earlier notified to the contrary by any Bank by
1:00 p.m. (Boston time) on any Drawdown Date) assume that each Bank has made
available (or will before the end of such Business Day make available) to the
Agent the amount of such Bank's Commitment Percentage with respect to the Loan
to be made on such Drawdown Date, and the Agent may (but shall not be required
to), in reliance upon such assumption, make available to the Borrowers a
corresponding amount. If any Bank makes such amount available to the Agent on a
date after such Drawdown Date, such Bank shall pay the Agent on demand an amount
equal to the product of (i) the average, computed for the period referred to in
clause (iii) below, of the weighted average annual interest rate paid by the
Agent for federal funds acquired by the Agent during each day included in such
period multiplied by (ii) the amount equal to such Bank's Commitment Percentage
of such Loan, multiplied by (iii) a fraction, the numerator of which is the
number of days that elapse from and including such Drawdown Date to but not
including the date on which the amount equal to such Bank's Commitment
Percentage of such Loan shall become immediately available to the Agent and the
denominator of which is 365. A statement of the Agent submitted to such Bank
with respect to any amounts owing under this paragraph shall be prima facie
evidence of the amount due and owing to the Agent by such Bank. If such amount
is not in fact made available to the Agent by such Bank within three (3)
Business Days of such Drawdown Date, the Agent shall be entitled to debit the
Borrowers' accounts to recover such amount from the Borrowers, with interest
thereon at the rate per annum applicable to any Loan made on such Drawdown Date.


     Election of Eurodollar Rate; Notice of Election; Interest Periods; Minimum
Amounts.

     (a) At the Parent's option, so long as no Default or Event of Default has
occurred and is then continuing, the Parent may (i) elect to convert any Base
Rate Loan or a portion thereof to a Eurodollar Loan, (ii) at the time of any
Loan and Letter of Credit Request, specify that such requested Loan shall be a
Eurodollar Loan, or (iii) upon expiration of the applicable Interest Period,
elect to maintain an existing Eurodollar Loan as such, provided that the Parent
gives notice to the Agent pursuant to 2.6(b) hereof. Upon determining any
Eurodollar Rate, the Agent shall forthwith provide notice thereof to the Parent
and each Bank, and each such notice to the Parent shall be considered prima
facie correct and binding, absent manifest error.

     (b) Three (3) Eurodollar Business Days prior to the making of any
Eurodollar Loan or the conversion of any Base Rate Loan to a Eurodollar Loan,
or, in the case of an outstanding Eurodollar Loan, the expiration date of the
applicable Interest Period, the Parent shall give written or telecopy notice
received by the Agent not later than 12:00 noon (Boston time) of its election
pursuant to 2.6(a). Each such notice delivered to the Agent shall specify the
aggregate principal amount of the Loans to be borrowed or maintained as or
converted to Eurodollar Loans and the requested duration of the Interest Period
that will be applicable to each such Eurodollar Loan, and shall be irrevocable
and binding upon the Borrowers. If the Parent shall fail to give the Agent
notice of its election hereunder together with all of the other information
required by 2.4 and this 2.6(b) with respect to any Loan, whether at the end of
an Interest Period or otherwise, such Loan shall be deemed a Base Rate Loan. The
Agent shall promptly notify each Bank in writing (or by telephone confirmed in
writing or by telecopy) of such election.
<PAGE>
 
     (c) Notwithstanding anything herein to the contrary, the Borrowers may not
specify an Interest Period that would extend beyond the Maturity Date.

     (d) All Eurodollar Loans shall be in a minimum amount of not less than
$1,000,000. In no event shall the Borrowers have more than five (5) different
maturities of borrowings of Eurodollar Loans outstanding at any time.

     Interest.

     The outstanding principal amount of the Loans shall bear interest at the
rate per annum equal to the Applicable Rate. Interest shall be payable (a)
quarterly in arrears on the last Business Day of each fiscal quarter for the
fiscal quarter ending on such date, on Base Rate Loans, (b) on the last day of
the applicable Interest Period, and if such Interest Period is longer than three
(3) months, also on the last day of the third month following the commencement
of such Interest Period, on Eurodollar Loans, and (c) on the Maturity Date for
all Loans.

     Maturity of the Loans and Reimbursement Obligations.

     The Loans and all unpaid Reimbursement Obligations shall be due and payable
on the Maturity Date. Each of the Borrowers promises to pay on the Maturity Date
all Loans and all unpaid Reimbursement Obligations outstanding on such date,
together with any and all accrued and unpaid interest thereon and any fees and
other amounts owing hereunder.

     Mandatory Repayments of the Loans.

     If at any time the outstanding amount of the Loans plus the Maximum Drawing
Amount of all outstanding Letters of Credit exceeds the Total Commitment whether
by reduction of the Total Commitment or otherwise, then the Borrowers shall
immediately pay the amount of such excess to the Agent (a) for application to
the Loans (subject to 4.7), or (b) if no Loans shall be outstanding, to be held
by the Agent for the benefit of the Banks as collateral security for the
Reimbursement Obligations provided, however, that if the amount of cash
collateral held by the Agent pursuant to this 2.9(b) exceeds the Maximum Drawing
Amount, the Agent shall return such excess to the Borrowers.

     Optional Prepayments or Repayments of Loans.

     Subject to the terms and conditions of 4.7, the Borrowers shall have the
right, at their election, to repay or prepay the outstanding amount of the
Loans, as a whole or in part, at any time without penalty or premium. The
Borrowers shall give the Agent, no later than 12:00 noon (Boston time) three (3)
Business Days prior to such proposed prepayment or repayment, written notice (or
telephonic notice confirmed in writing or by telecopy) of any proposed
prepayment or repayment pursuant to this 2.10, specifying the proposed date of
prepayment or repayment of Loans and the principal amount to be paid (in
integral multiples of $1,000,000, or, if less, the balance of the Loans). The
Agent shall promptly notify each Bank by written notice (or telephonic notice

     LETTERS OF CREDIT.

     Letter of Credit Commitments.


     (a) Subject to the terms and conditions hereof and the execution and
receipt of a Loan and Letter of Credit Request reflecting the Maximum Drawing
Amount of all Letters of Credit (including the requested Letter of Credit) and a
Letter of Credit Application, the Agent, on behalf of the Banks and in reliance
upon the agreement of the Banks set forth in 3.1(b) and upon the representations
and warranties of the Borrowers contained herein, agrees to issue standby
letters of credit, in such form as may be requested from time to time by the
Parent as agent for the Borrowers and agreed to by the Agent; provided, however,
that, after giving effect to such request, the aggregate Maximum Drawing Amount
of all letters of credit issued under this 3.1(a) (the "Letters of Credit")
shall not exceed $50,000,000, such Maximum Drawing Amount plus the aggregate
outstanding principal of all Loans shall not exceed the Total Commitment, and no
Letter of Credit shall have an expiration date later than the earlier of (i) one
year after the date of issuance of the Letter of Credit, or (ii) thirty (30)
days prior to the Maturity Date. The letters of credit listed in Schedule 3.1(a)
issued by the Agent under the Original Credit Agreement shall be Letters of
Credit under this Agreement.

     (b) Each Bank severally agrees that it shall be absolutely liable, without
regard to the occurrence of any Default or Event of Default or any other
condition precedent whatsoever, to the extent of such Bank's Commitment
Percentage thereof, to reimburse the Agent on demand for the amount of each
draft paid by the Agent under each Letter of Credit to the extent that such
amount is not reimbursed by the Borrowers pursuant to 3.2 (such agreement for a
Bank being called herein the "Letter of Credit Participation" of such Bank).

     (c) Each such payment made by a Bank shall be treated as the purchase by
such Bank of a participating interest in the Borrowers' Reimbursement Obligation
under 3.2 in an amount equal to such payment. Each Bank shall share in
accordance with its participating interest in any interest which accrues
pursuant to 3.2.

     Reimbursement Obligation of the Borrowers.

     In order to induce the Agent to issue, extend and renew each Letter of
Credit and the Banks to participate therein, the Borrowers hereby agree to
reimburse or pay to the Agent with respect to each Letter of Credit issued,
extended or renewed by the Agent hereunder as follows:

     (a) on each date that any draft presented under any Letter of Credit is
honored by the Agent or the Agent otherwise makes payment with respect thereto
(the "L/C Payment Date"), (i) the amount paid by the Agent under or with respect
to such Letter of Credit, and (ii) the amount of any taxes, fees, charges or
other costs and expenses whatsoever incurred by the Agent in connection with any
payment made by the Agent under, or with respect to, such Letter of Credit,
provided however, if the Borrowers do not reimburse such Agent on the L/C
Payment Date, such amount shall, provided that no Event of Default under 12(g)
or 12(h) has occurred, become automatically a Base Rate Loan advanced hereunder
in an amount equal to such sum; and

     (b) upon the Maturity Date or the acceleration of the Reimbursement
Obligations with respect to all Letters of Credit in accordance with 12, an
amount equal to the then Maximum Drawing Amount of all Letters of Credit, which
amount shall be held by the Agent for the benefit of the Banks and the Agent as
cash collateral for all Reimbursement Obligations.
<PAGE>
 
     Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrowers under this 3.2 at any time from the date such amounts become due
and payable (whether as stated in this 3.2, by acceleration or otherwise) until
payment in full (whether before or after judgment) shall be payable to the Agent
on demand at the rate specified in 4.5 for overdue amounts.

     Letter of Credit Payments.

     If any draft shall be presented or other demand for payment shall be made
under any Letter of Credit, the Agent shall notify the Borrowers of the date and
amount of the draft presented or demand for payment and of the date and time
when it expects to pay such draft or honor such demand for payment. On the date
that such draft is paid or other payment is made by the Agent, the Agent shall
promptly notify the Banks of the amount of any unpaid Reimbursement Obligation.
All such unpaid Reimbursement Obligations with respect to Letters of Credit
shall be deemed to be Base Rate Loans. No later than 3:00 p.m. (Boston time) on
the Business Day next following the receipt of such notice, each Bank shall make
available to the Agent, at the Agent's Head Office, in immediately available
funds, such Bank's Commitment Percentage of such unpaid Reimbursement
Obligation, together with an amount equal to the product of (a) the average,
computed for the period referred to in clause (c) below, of the weighted average
interest rate paid by the Agent for federal funds acquired by the Agent during
each day included in such period, multiplied by (b) the amount equal to such
Bank's Commitment Percentage of such unpaid Reimbursement Obligation, multiplied
by (c) a fraction, the numerator of which is the number of days that have
elapsed from and including the date the Agent paid the draft presented for honor
or otherwise made payment until the date on which such Bank's Commitment
Percentage of such unpaid Reimbursement Obligation shall become immediately
available to the Agent, and the denominator of which is 365. The responsibility
of the Agent to the Borrowers and the Banks shall be only to determine that the
documents (including each draft) delivered under each Letter of Credit in
connection with such presentment shall be in conformity in all material respects
with such Letter of Credit.

     Obligations Absolute.

     The Borrowers' obligations under this 3 shall be absolute and unconditional
under any and all circumstances and irrespective of the occurrence of any
Default or Event of Default or any condition precedent whatsoever or any setoff,
counterclaim or defense to payment which the Borrowers may have or have had
against the Agent, any Bank or any beneficiary of a Letter of Credit. The
Borrowers further agree with the Agent and the Banks that the Agent and the
Banks shall not be responsible for, and the Borrowers' Reimbursement Obligations
under 3.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrowers, the beneficiary of any Letter of
Credit or any financing institution or other party to which any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrowers against
the beneficiary of any Letter of Credit or any such transferee. The Agent and
the Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit. The Borrowers agree that
any action taken or omitted by the Agent or any Bank under or in connection with
each Letter of Credit and the related drafts and documents, if done in good
faith, shall be binding upon the Borrowers and shall not result in any liability
on the part of the Agent or any Bank to the Borrowers.
<PAGE>
 
     Reliance by Agent.

     To the extent not inconsistent with 3.4, the Agent shall be entitled to
rely, and shall be fully protected in relying upon, any Letter of Credit, draft,
resolution, written notice, written consent, certificate, affidavit, letter,
cablegram, telegram, telecopy, telex or teletype message, statement, order or
other document believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel, independent accountants and other experts selected by the Agent;
provided that any of the above may be transmitted by facsimile if allowed by the
Letter of Credit.

     FEES, PAYMENTS, AND COMPUTATIONS; JOINT AND SEVERAL LIABILITY.

     Fees.

     (a) Commitment Fee. The Borrowers agree to pay to the Banks a commitment
fee (the "Commitment Fee") equal to the Applicable Commitment Fee Rate
multiplied by the amount of the unused portion of the Total Commitment during
each fiscal quarter or portion thereof from the Closing Date to the Maturity
Date (or to the date of termination in full of the Total Commitment, if
earlier). This Commitment Fee shall be payable quarterly in arrears on the last
day of each fiscal quarter for the fiscal quarter then ended commencing on the
last day of the calendar month in which the conditions set forth in 9 hereof are
first satisfied, with a final payment on the Maturity Date. The Commitment Fee
shall be shared pro rata by the Banks in accordance with their respective
Commitment Percentages.

     (b) Letter of Credit Fee. The Borrowers shall pay a fee (the "Letter of
Credit Fee") to the Agent equal to the Applicable L/C Fee Rate multiplied by the
average Maximum Drawing Amount of Letters of Credit outstanding during each
fiscal quarter, payable quarterly in arrears on the last day of each fiscal
quarter for the fiscal quarter then ended. The Borrowers shall also pay in
advance on the date of issuance of each Letter of Credit an issuance fee to the
Agent for its account equal to one eighth of one percent (1/8%) per annum on the
Maximum Drawing Amount of each Letter of Credit (the "Issuance Fee"). The Letter
of Credit Fee (but not the Issuance Fee) shall be shared pro-rata by each of the
Banks in accordance with their respective Commitment Percentages. The Borrowers
shall also pay the customary administrative fees of the Agent with respect to
the Letters of Credit, including, without limitation, fees for modifying such
Letters of Credit.

     (c) The Borrowers shall pay an agent's fee to the Agent at the times and in
the amount as shall be agreed upon by the Borrowers and the Agent.
<PAGE>
 
     Payments.

     (a) All payments of principal, interest, Reimbursement Obligations, fees
and any other amounts due hereunder or under any of the other Loan Documents
shall be made to the Agent, for the respective accounts of the Banks and the
Agent, received at the Agent's Head Office in immediately available funds by
12:00 noon (Boston time) on any due date.

     (b) All payments by the Borrowers hereunder and under any of the other Loan
Documents shall be made without setoff or counterclaim and free and clear of and
without deduction for any taxes, levies, imposts, duties, charges, fees,
deductions, withholdings, compulsory loans, restrictions or conditions of any
nature now or hereafter imposed or levied by any jurisdiction or any political
subdivision thereof or taxing or other authority therein unless the Borrowers
are compelled by law to make such deduction or withholding. If any such
obligation is imposed upon the Borrowers with respect to any amount payable by
them hereunder or under any of the other Loan Documents, the Borrowers will pay
to the Agent, for the account of the Banks or (as the case may be) the Agent, on
the date on which such amount is due and payable hereunder or under such other
Loan Document, such additional amount in Dollars as shall be necessary to enable
the Banks or the Agent to receive the same net amount which the Banks or the
Agent would have received on such due date had no such obligation been imposed
upon the Borrowers. The Borrowers will deliver promptly to the Bank certificates
or other valid vouchers for all taxes or other charges deducted from or paid
with respect to payments made by the Borrowers hereunder or under such other
Loan Document.

     Computations.

     All computations of interest on the Loans and of Letter of Credit Fees or
other fees shall be based on a 365- or 366-day year except that computations of
interest on Eurodollar Loans shall be based on a 360- day year, and shall be
paid for the actual number of days elapsed. Whenever a payment hereunder or
under any of the other Loan Documents becomes due on a day that is not a
Business Day, the due date for such payment shall be extended to the next
Business Day, and interest shall accrue during such extension.

     Capital Adequacy.

     If any present or future law, governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law) or the
interpretation thereof by a court or governmental authority with appropriate
jurisdiction affects the amount of capital required or expected to be maintained
by any Bank or the Agent or any corporation controlling such Bank or the Agent
and such Bank or the Agent determines that the amount of capital required to be
maintained by it is increased by or based upon the existence of such Bank's or
the Agent's Loans, Letter of Credit Participations or Letters of Credit, or
commitment with respect thereto, then such Bank or the Agent may notify the
Borrowers of such fact. To the extent that the costs of such increased capital
requirements are not reflected in the Base Rate (if relating to Base Rate
Loans), the Borrowers and such Bank or (as the case may be) the Agent shall
thereafter attempt to negotiate in good faith, within thirty (30) days of the
day on which the Borrowers receive such notice, an adjustment payable hereunder
that will adequately compensate such Bank or the Agent in light of these
circumstances. If the Borrowers and such Bank or the Agent are unable to agree
to such adjustment within thirty (30) days of the date on which the Borrowers
receive such notice, then commencing on the date of such notice (but not earlier
than the effective date of any such increased capital requirement), the fees
payable hereunder shall increase by an amount that will, in such Bank's or the
Agent's reasonable determination, provide adequate compensation. Each Bank and
the Agent shall allocate such cost increases among its customers in good faith
and on an equitable basis.
<PAGE>
 
     Interest on Overdue Amounts.

     Overdue principal and (to the extent permitted by applicable law) interest
on the Loans and all other overdue amounts payable hereunder or under any of the
other Loan Documents shall bear interest compounded monthly and be payable on
demand at a rate per annum equal to the Base Rate plus two percentage points
(2.00%) until such overdue amount shall be paid in full (after as well as before
judgment).

     Interest Limitation.

     Notwithstanding any other term of this Agreement or any Note or any other
document referred to herein or therein, the maximum amount of interest which may
be charged to or collected from any person liable hereunder or under any Note by
any Bank shall be absolutely limited to, and shall in no event exceed, the
maximum amount of interest which could lawfully be charged or collected under
applicable law (including, to the extent applicable, the provisions of Section
5197 of the Revised Statutes of the United States of America, as amended, 12
U.S.C. Section 85, as amended), so that the maximum of all amounts constituting
interest under applicable law, howsoever computed, shall never exceed as to any
Person liable therefor such lawful maximum, and any term of this Agreement, the
Notes, the Letter of Credit Applications, or any other document referred to
herein or therein which could be construed as providing for interest in excess
of such lawful maximum shall be and hereby is made expressly subject to and
modified by the provisions of this paragraph.

     Eurodollar Indemnity.

     The Borrowers agree to indemnify the Banks and the Agent and to hold them
harmless from and against any reasonable loss, cost or expense that the Banks
and the Agent may sustain or incur as a consequence of (a) default by the
Borrowers in payment of the principal amount of or any interest on any
Eurodollar Loans as and when due and payable, including any such loss or expense
arising from interest or fees payable by any Bank or the Agent to lenders of
funds obtained by it in order to maintain its Eurodollar Loans, (b) default by
the Borrowers in making a borrowing or conversion after the Borrowers have given
(or are deemed to have given) notice pursuant to 2.4 or 2.6, and (c) the making
of any payment of a Eurodollar Loan or the making of any conversion of any such
Eurodollar Loan to a Base Rate Loan on a day that is not the last day of the
applicable Interest Period with respect thereto. Such loss or reasonable expense
shall include an amount equal to the excess, if any, as reasonably determined by
each Bank of (i) its cost of obtaining the funds for the Loan being paid,
prepaid, converted, or not borrowed (based on the Eurodollar Rate) for the
period from the date of such payment, prepayment, conversion, or failure to
borrow to the last day of the Interest Period for such Loan (or, in the case of
a failure to borrow, the Interest Period for the Loan which would have commenced
on the date of such failure to borrow) over (ii) the amount of interest (as
reasonably determined by such Bank) that would be realized by such Bank in
reemploying the funds so paid, prepaid, converted, or not borrowed for such
period or Interest Period, as the case may be.
<PAGE>
 
     Illegality; Inability to Determine Eurodollar Rate. Notwithstanding any
other provision of this Agreement, if (a) the introduction of, any change in, or
any change in the interpretation of, any law or regulation applicable to any
Bank or the Agent shall make it unlawful, or any central bank or other
governmental authority having jurisdiction thereof shall assert that it is
unlawful, for any Bank or the Agent to perform its obligations in respect of any
Eurodollar Loans, or (b) if any Bank or the Agent shall reasonably determine
with respect to Eurodollar Loans that (i) by reason of circumstances affecting
any Eurodollar interbank market, adequate and reasonable methods do not exist
for ascertaining the Eurodollar Rate which would otherwise be applicable during
any Interest Period, or (ii) deposits of Dollars in the relevant amount for the
relevant Interest Period are not available to such Bank or the Agent in any
Eurodollar interbank market, or (iii) the Eurodollar Rate does not or will not
accurately reflect the cost to such Bank or the Agent of obtaining or
maintaining the applicable Eurodollar Loans during any Interest Period, then
such Bank or the Agent shall promptly give telephonic, telex or cable notice of
such determination to the Borrowers (which notice shall be conclusive and
binding upon the Borrowers). Upon such notification by such Bank or the Agent,
the obligation of the Banks and the Agent to make Eurodollar Loans shall be
suspended until the Banks or the Agent, as the case may be, determine that such
circumstances no longer exist, and to the extent permitted by law the
outstanding Eurodollar Loans shall continue to bear interest at the applicable
rate based on the Eurodollar Rate until the end of the applicable Interest
Period, and thereafter shall be deemed converted to Base Rate Loans in equal
principal amounts.

     Additional Costs, Etc.

     If any present or future applicable law, which expression, as used herein,
includes statutes, rules and regulations thereunder and interpretations thereof
by any competent court or by any governmental or other regulatory body or
official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Bank or the Agent by any central
bank or other fiscal, monetary or other authority (whether or not having the
force of law), shall impose on any Bank or the Agent any tax, levy, impost,
duty, charge fees, deduction or withholdings of any nature or requirements with
respect to this Agreement, the other Loan Documents, the Loans, such Bank's
Commitment, the Letters of Credit or any class of loans or commitments or
letters of credit of which any of the Loans, such Bank's Commitment or the
Letters of Credit forms a part, and the result of any of the foregoing is:
<PAGE>
 
          (i) to increase the cost to such Bank or the Agent of making, funding,
     issuing, renewing, extending or maintaining the Loans, such Bank's
     Commitment, or the Letters of Credit; or

          (ii) to reduce the amount of principal, interest or other amount
     payable to such Bank or the Agent hereunder on account of such Bank's
     Commitment, the Loans, drawings under the Letters of Credit, or

          (iii)to require such Bank or the Agent to make any payment or to
     forego any interest or other sum payable hereunder, the amount of which
     payment or foregone interest or other sum is calculated by reference to the
     gross amount of any sum receivable or deemed received by such Bank from the
     Borrowers hereunder,

then, and in each such case, the Borrowers will, upon demand made by such Bank
or the Agent at any time and from time to time and as often as the occasion
therefor may arise, pay to such Bank such additional amounts as will be
sufficient to compensate such Bank for such additional cost, reduction, payment
or foregone interest or other sum (after such Bank shall have allocated the same
fairly and equitably among all customers of any class generally affected
thereby).

     Certificate.

     A certificate setting forth any additional amounts payable pursuant to 4.7
or 4.9 and a reasonable explanation of such amounts which are due, submitted by
any Bank or the Agent to the Borrowers, shall be conclusive, absent manifest
error, that such amounts are due and owing.

     Concerning Joint and Several Liability of the Borrowers.

     (a) Each of the Borrowers is accepting joint and several liability
hereunder and under the other Loan Documents in consideration of the financial
accommodations to be provided by the Banks and the Agent under this Agreement,
for the mutual benefit, directly and indirectly, of each of the Borrowers and in
consideration of the undertakings of each other Borrower to accept joint and
several liability for the Obligations.

     (b) Each of the Borrowers, jointly and severally, hereby irrevocably and
unconditionally accepts, not merely as a surety but also as a co-debtor, joint
and several liability with the other Borrowers, with respect to the payment and
performance of all of the Obligations (including, without limitation, any
Obligations arising under this 4.11), it being the intention of the parties
hereto that all the Obligations shall be the joint and several Obligations of
each of the Borrowers without preferences or distinction among them.

     (c) If and to the extent that any of the Borrowers shall fail to make any
payment with respect to any of the Obligations as and when due or to perform any
of the Obligations in accordance with the terms thereof, then in each such event
the other Borrowers will make such payment with respect to, or perform, such
Obligation.

     (d) The Obligations of each of the Borrowers under the provisions of this
4.11 constitute full recourse Obligations of each of the Borrowers enforceable
against each such corporation to the full extent of its properties and assets,
irrespective of the validity, regularity or enforceability of this Agreement or
any other circumstance whatsoever.

     (e) Except as otherwise expressly provided in this Agreement, each of the
Borrowers hereby waives notice of acceptance of its joint and several liability,
notice of any Loans made under this Agreement, notice of any action at any time
taken or omitted by the Banks or the Agent under or in respect of any of the
Obligations, and, generally, to the extent permitted by applicable law, all
demands, notices and 
<PAGE>
 
other formalities of every kind in connection with this
Agreement. Each of the Borrowers hereby assents to, and waives notice of, any
extension or postponement of the time for the payment of any of the Obligations,
the acceptance of any payment of any of the Obligations, the acceptance of any
partial payment thereon, any waiver, consent or other action or acquiescence by
the Banks or the Agent at any time or times in respect of any default by any of
the Borrowers in the performance or satisfaction of any term, covenant,
condition or provision of this Agreement, any and all other indulgences
whatsoever by the Banks or the Agent in respect of any of the Obligations, and
the taking, addition, substitution or release, in whole or in part, at any time
or times, of any security for any of the Obligations or the addition,
substitution or release, in whole or in part, of any of the Borrowers. Without
limiting the generality of the foregoing, each of the Borrowers assents to any
other action or delay in acting or failure to act on the part of the Banks or
the Agent with respect to the failure by any of the Borrowers to comply with any
of its respective Obligations, including, without limitation, any failure
strictly or diligently to assert any right or to pursue any remedy or to comply
fully with applicable laws or regulations thereunder, which might, but for the
provisions of this 4.11, afford grounds for terminating, discharging or
relieving any of the Borrowers, in whole or in part, from any of its Obligations
under this 4.11, it being the intention of each of the Borrowers that, so long
as any of the Obligations hereunder remain unsatisfied, the Obligations of such
Borrowers under this 4.11 shall not be discharged except by performance and then
only to the extent of such performance. The Obligations of each of the Borrowers
under this 4.11 shall not be diminished or rendered unenforceable by any winding
up, reorganization, arrangement, liquidation, re-construction or similar
proceeding with respect to any of the Borrowers or the Banks or the Agent. The
joint and several liability of the Borrowers hereunder shall continue in full
force and effect notwithstanding any absorption, merger, amalgamation or any
other change whatsoever in the name, membership, constitution or place of
formation of any of the Borrowers, the Agent, or the Banks.

     (f) The provisions of this 4.11 are made for the benefit of the Banks and
the Agent and their successors and assigns, and may be enforced in good faith
against them from time to time against any or all of the Borrowers as often as
occasion therefor may arise and without requirement on the part of the Banks or
the Agent first to marshal any of their claims or to exercise any of their
rights against any other Borrower or to exhaust any remedies available to them
against any other Borrower or to resort to any other source or means of
obtaining payment of any of the Obligations hereunder or to elect any other
remedy. The provisions of this 4.11 shall remain in effect until all of the
Obligations shall have been paid in full or otherwise fully satisfied. If at any
time, any payment, or any part thereof, made in respect of any of the
Obligations, is rescinded or must otherwise be restored or returned by the Banks
upon the insolvency, bankruptcy or reorganization of any of the Borrowers, or
otherwise, the provisions of this 4.11 will forthwith be reinstated in effect,
as though such payment had not been made.

     New Borrowers.

     Any newly-created or acquired Subsidiaries shall become Borrowers hereunder
by signing Notes (or, at the option of the Agent, allonges to existing Notes),
entering into an amendment to this Agreement with the other parties hereto
providing that such Subsidiary shall become a Borrower hereunder, and providing
such other documentation as the Banks or the Agent may reasonably request
including, without limitation, documentation with respect to conditions noted in
9 and 10 hereof. In such event, the Agent is hereby authorized by the parties to
amend Schedule 1 hereto to include each such Subsidiary as a Borrower hereunder.
<PAGE>
 
     REPRESENTATIONS AND WARRANTIES.

     The Borrowers jointly and severally represent and warrant to the Banks and
the Agent as follows:

     Corporate Authority.

          (a) Incorporation; Good Standing. Each of the Borrowers (i) is a
     corporation duly organized, validly existing and in good standing under the
     laws of its respective state of incorporation, (ii) has all requisite
     corporate power to own its property and conduct its business as now
     conducted and as presently contemplated, and (iii) is in good standing as a
     foreign corporation and is duly authorized to do business in each
     jurisdiction in which its property or business as presently conducted or
     contemplated makes such qualification necessary, except where a failure to
     be so qualified would not have a material adverse effect on the business,
     assets or financial condition of the Borrowers considered as a whole.

          (b) Authorization. The execution, delivery and performance of the Loan
     Documents and the transactions contemplated hereby and thereby (i) are
     within the corporate authority of each of the Borrowers, (ii) have been
     duly authorized by all necessary corporate proceedings, (iii) do not
     conflict with or result in any material breach or contravention of any
     provision of law, statute, rule or regulation to which any of the Borrowers
     is subject or any judgment, order, writ, injunction, license or permit
     applicable to any of the Borrowers so as to materially adversely affect the
     assets, business or any activity of the Borrowers, and (iv) do not conflict
     with any provision of the corporate charter or bylaws of the Borrowers or
     any agreement or other instrument binding upon the Borrowers.

          (c) Enforceability. The execution, delivery and performance of the
     Loan Documents will result in valid and legally binding obligations of the
     Borrowers enforceable against each in accordance with the respective terms
     and provisions hereof and thereof, except as enforceability is limited by
     bankruptcy, insolvency, reorganization, moratorium or other laws relating
     to or affecting generally the enforcement of creditors' rights and except
     to the extent that availability of the remedy of specific performance or
     injunctive relief or other equitable remedy is subject to the discretion of
     the court before which any proceeding therefor may be brought.

     Governmental Approvals.

     The execution, delivery and performance by the Borrowers of the Loan
Documents and the transactions contemplated hereby and thereby do not require
any approval or consent of, or filing with, any governmental agency or authority
other than those already obtained.

     Title to Properties; Leases.

     The Borrowers own all of the assets reflected in the consolidated or
combined balance sheets as at the Balance Sheet Date or acquired since that date
(except property and assets sold or otherwise disposed of in the ordinary course
of business since that date), subject to no mortgages, capitalized leases,
conditional sales agreements, title retention agreements, liens or other
encumbrances except Permitted Liens.
<PAGE>
 
     Financial Statements; Solvency.

          (a) There has been furnished to the Banks (i) the consolidated balance
     sheet of the Borrowers dated the Balance Sheet Date and consolidated
     statements of operations for the fiscal year then ended, Certified by Ernst
     & Young LLP or such other independent accounting firm acceptable to the
     Banks (the "Accountants"), and (ii) a consolidated and consolidating
     balance sheet and related consolidated and consolidating statement of
     operations of the Borrowers dated the Balance Sheet Date for the fiscal
     quarter then ended. Said balance sheets and statements of operations have
     been prepared in accordance with GAAP, fairly present in all material
     respects the financial condition of the Borrowers on a consolidated basis,
     as at the close of business on the date thereof and the results of
     operations for the period then ended. There are no contingent liabilities
     of the Borrowers as of such date involving amounts of $250,000 or more in
     the aggregate known to the officers of the Borrowers which have not been
     disclosed in said balance sheets and the related notes thereto, as the case
     may be.

          (b) The Borrowers (both before and after giving effect to the
     transactions contemplated by this Agreement) are solvent (i.e., on a
     consolidated basis they have assets having a fair value in excess of the
     amount required to pay their probable liabilities on their existing debts
     as they become absolute and matured) and have, and expect to have, the
     ability to pay their debts from time to time incurred in connection
     therewith as such debts mature.

     No Material Changes, Etc.

     Since the Balance Sheet Date, there have occurred no material adverse
changes in the financial condition or business of the Borrowers as shown on or
reflected in the consolidated balance sheet of such corporations as at the
Balance Sheet Date, or the consolidated statement of income for the fiscal year
then ended other than changes in the ordinary course of business which have not
had any material adverse effect either individually or in the aggregate on the
business or financial condition of any Borrower. Since the Balance Sheet Date,
there has not been any Distribution.

     Permits, Franchises, Patents, Copyrights, Etc. Each of the Borrowers
possesses all franchises, patents, copyrights, trademarks, trade names, licenses
and permits, and rights in respect of the foregoing, adequate for the conduct of
its business substantially as now conducted without known conflict with any
rights of others.

     Litigation.

     To the knowledge of the Borrowers, except as shown on Schedule 5.7 hereto,
there are no actions, suits, proceedings or investigations of any kind pending
or threatened against any Borrower before any court, tribunal or administrative
agency or board which, if adversely determined, might, either in any case or in
the aggregate, materially adversely affect the properties, assets, financial
condition or business of the Borrowers considered as a whole, or materially
impair the right of the Borrowers to carry on business substantially as now
conducted, or result in any substantial liability not adequately covered by
insurance, or for which adequate reserves (as defined by GAAP) are not
maintained on the consolidated balance sheet or which question the validity of
any of the Loan Documents, or any action taken or to be taken pursuant hereto or
thereto.
<PAGE>
 
     No Materially Adverse Contracts, Etc.

     None of the Borrowers is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which would be
reasonably likely in the future to have a materially adverse effect on the
business, assets or financial condition of the Borrowers considered as a whole.
None of the Borrowers is a party to any contract or agreement which in the
judgment of the Borrowers' officers has or is expected to have any materially
adverse effect on the business of the Borrowers considered as a whole, except as
otherwise reflected in adequate reserves (as defined by GAAP).

     Compliance With Other Instruments, Laws, Etc.

     None of the Borrowers is violating any provision of its charter documents
or by-laws or any agreement or instrument by which any of them may be subject or
by which any of them or any of their properties may be bound or any decree,
order, judgment, or any statute, license, rule or regulation, in a manner which
could result in the imposition of substantial penalties or materially and
adversely affect the financial condition, properties or business of the
Borrowers considered as a whole.

     Tax Status.

     The Borrowers have made or filed all federal and state income and all other
tax returns, reports and declarations required by any jurisdiction to which any
of them are subject (unless and only to the extent that any Borrower has set
aside on its books provisions reasonably adequate for the payment of all unpaid
and unreported taxes); and have paid all taxes and other governmental
assessments and charges that are material in amount, shown or determined to be
due on such returns, reports and declarations, except those being contested in
good faith; and have set aside on their books provisions reasonably adequate for
the payment of all taxes for periods subsequent to the periods to which such
returns, reports or declarations apply. There are no unpaid taxes in an
aggregate amount of $100,000 or more claimed to be due by the taxing authority
of any jurisdiction, and the officers of the Borrowers know of no basis for any
such claim.

     No Event of Default.

     No Default or Event of Default has occurred and is continuing.

     Holding Company and Investment Company Acts.

     None of the Borrowers is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is any of them a
"registered investment company", or an "affiliated company" or a "principal
underwriter" of a "registered investment company", as such terms are defined in
the Investment Company Act of 1940, as amended.

office, which purports to cover, affect or give notice of any present or
possible future lien on, or security interest in, any assets or property of any
of the Borrowers or rights thereunder.

                                        4

     Employee Benefit Plans.

     (a) In General. Each Employee Benefit Plan and each Guaranteed Pension Plan
has been maintained and operated in compliance in all material respects with the
provisions of ERISA and, to the extent applicable, the Code, including but not
limited to the provisions thereunder respecting prohibited transactions and the
bonding of fiduciaries and other persons handling plan funds as required by 412
of ERISA. The Borrowers have heretofore delivered to the Agent the most recently
completed annual report, Form 5500, with all required attachments, and actuarial
statement required to be submitted under 103(d) of ERISA, with respect to each
Guaranteed Pension Plan.

     (b) Terminability of Welfare Plans. No Employee Benefit Plan which is an
employee welfare benefit plan within the meaning of 3(1) or 3(2)(B) of ERISA,
provides benefit coverage subsequent to termination of employment except as
required by Title I, Part 6 of ERISA or applicable state insurance laws. Any
Borrower may terminate each such Plan at any time (or at any time subsequent to
the expiration of any applicable bargaining agreement) in the discretion of such
Borrower without liability to any Person other than for claims arising prior to
termination.

     (c) Guaranteed Pension Plans. Each contribution required to be made to a
Guaranteed Pension Plan, whether required to be made to avoid the incurrence of
an accumulated funding deficiency, the notice or lien provisions of 302(f) of
ERISA, or otherwise, has been timely made. No waiver of an accumulated funding
deficiency or extension of amortization periods has been received with respect
to any Guaranteed Pension Plan, and neither any of the Borrowers nor any ERISA
Affiliate is obligated to or has posted security in connection with an amendment
of a Guaranteed Pension Plan pursuant to 307 of ERISA or 401(a)(29) of the Code.
No liability to the PBGC (other than required insurance premiums, all of which
have been paid) has been incurred by any Borrower or any ERISA Affiliate with
respect to any Guaranteed Pension Plan and there has not been any ERISA
Reportable Event, or any other event or condition which presents a material risk
of termination of any Guaranteed Pension Plan by the PBGC. Based on the latest
valuation of each Guaranteed Pension Plan (which in each case occurred within
twelve months of the date of this representation), and on the actuarial methods
and assumptions employed for that valuation, the aggregate benefit liabilities
of all such Guaranteed Pension Plans within the meaning of 4001 of ERISA did not
exceed the aggregate value of the assets of all such Guaranteed Pension Plans,
disregarding for this purpose the benefit liabilities and assets of any
Guaranteed Pension Plan with assets in excess of benefit liabilities.
<PAGE>
 
     (d) Multiemployer Plans. None of the Borrowers nor any ERISA Affiliate has
incurred any material liability (including secondary liability) to any
Multiemployer Plan as a result of a complete or partial withdrawal from such
Multiemployer Plan under 4201 of ERISA or as a result of a sale of assets
described in 4204 of ERISA. None of the Borrowers nor any ERISA Affiliate has
been notified that any Multiemployer Plan is in reorganization or is insolvent
under and within the meaning of 4241 or 4245 of ERISA or is at risk of entering
reorganization or becoming insolvent, or that any Multiemployer Plan intends to
terminate or has been terminated under 4041A of ERISA

     Use of Proceeds.

     The proceeds of the Loans shall be used for general corporate purposes,
including to repay certain existing Indebtedness of the Borrowers, for working
capital purposes, for Capital Expenditures, for Letters of Credit, and for
additional acquisitions permitted by 7.4 hereof or otherwise approved in writing
by the Banks. No proceeds of the Loans shall be used in any way that will
violate Regulations G, T, U or X of the Board of Governors of the Federal
Reserve System.

     Environmental Compliance.

     The Borrowers have taken all reasonable and prudent steps to investigate
the past and present condition and usage of the Real Properties and the
operations conducted thereon and, based upon such diligent investigation, have
determined that, except as shown on Schedule 5.16:

          (a) None of the Borrowers, nor any operator of their properties, is in
     violation, or alleged violation, of any judgment, decree, order, law,
     permit, license, rule or regulation pertaining to environmental matters,
     including without limitation, those arising under the Resource Conservation
     and Recovery Act ("RCRA"), the Comprehensive Environmental Response,
     Compensation and Liability Act of 1980 as amended ("CERCLA"), the Superfund
     Amendments and Reauthorization Act of 1986 ("SARA"), the Federal Clean
     Water Act, the Federal Clean Air Act, the Toxic Substances Control Act, or
     any other federal, state or local statute, regulation, ordinance, order or
     decree relating to health, safety or the environment (the "Environmental
     Laws"), which violation would have a material adverse effect on the
     business, assets or financial condition of the Borrowers considered as a
     whole.

          (b) None of the Borrowers has received notice from any third party
     including, without limitation, any federal, state or local governmental
     authority, (i) that any one of them has been identified by the United
     States Environmental Protection Agency ("EPA") as a potentially responsible
     party under CERCLA with respect to a site listed on the National Priorities
     List, 40 C.F.R. Part 300 Appendix B; (ii) that any hazardous waste, as
     defined by 42 U.S.C. 6903(5), any hazardous substances as defined by 42
     U.S.C. 9601(14), any pollutant or contaminant as defined by 42 U.S.C.
     9601(33) and any toxic substance, oil or hazardous materials or other
     chemicals or substances regulated by any Environmental Laws ("Hazardous
     Substances") which any one of them has generated, transported or disposed
     of has been found at any site at which a federal, state or local agency or
     other third party has conducted or has ordered that any Borrower conduct a
     remedial investigation, removal or other response action pursuant to any
     Environmental Law; or (iii) that it is or shall be a named party to any
     claim, action, cause of action, complaint, legal or administrative
     proceeding arising out of any third party's incurrence of costs, expenses,
     losses or damages of any kind whatsoever in connection with the release of
     Hazardous Substances.
<PAGE>
 
          (c) (i) No portion of the Real Property has been used for the
     handling, processing, storage or disposal of Hazardous Substances except in
     material compliance with applicable Environmental Laws; and no underground
     tank or other underground storage receptacle for Hazardous Substances is
     located on such properties except in material compliance with applicable
     Environmental Laws; (ii) in the course of any activities conducted by the
     Borrowers, or operators of the Real Property, no Hazardous Substances have
     been generated or are being used on such properties except in material
     compliance with applicable Environmental Laws; (iii) there have been no
     unpermitted Releases or threatened Releases of Hazardous Substances on,
     upon, into or from the Real Property, which Releases would have a material
     adverse effect on the value of such properties; (iv) to the best of the
     Borrowers' knowledge, there have been no Releases on, upon, from or into
     any real property in the vicinity of the Real Property which, through soil
     or groundwater contamination, may have come to be located on, and which
     would have a material adverse effect on the value of, such properties; and
     (v) in addition, any Hazardous Substances that have been generated on the
     Real Property have been transported offsite only by carriers having an
     identification number issued by the EPA, treated or disposed of only by
     treatment or disposal facilities maintaining valid permits as required
     under applicable Environmental Laws, which transporters and facilities, to
     the best of the Borrowers' knowledge, have been and are operating in
     material compliance with such permits and applicable Environmental Laws.

          (d) none of the Real Property is or shall be subject to any applicable
     environmental clean-up responsibility law or environmental restrictive
     transfer law or regulation, by virtue of the transactions set forth herein
     and contemplated hereby.

     Perfection of Security Interests.

     All filings, assignments, pledges and deposits of documents or instruments
have been made and all other actions have been taken that are necessary under
applicable law, or reasonably requested by the Agent or any of the Banks, to
establish and perfect the Agent's security interests in the Collateral as
described in the Security Documents. The Collateral and the Agent's rights with
respect to the Collateral are not subject to any setoff, claims, withholdings or
other defenses, except for Permitted Liens. The Borrowers are the owners of the
Collateral free from any lien, security interest, encumbrance and any other
claim or demand, except for Permitted Liens.
<PAGE>
 
     Certain Transactions.

Except as set forth on Schedule 5.18 and except for arm's length transactions
pursuant to which the Borrowers make payments in the ordinary course of business
upon terms no less favorable than the Borrowers could obtain from third parties,
none of the officers, directors, or employees of the Borrowers are presently a
party to any transaction with the Borrowers (other than for services as
employees, officers and directors), including any contract, agreement or other
arrangement providing for the furnishing of services to or by, providing for
rental of real or personal property to or from, or otherwise requiring payments
to or from any officer, director or such employee or, to the knowledge of the
Borrowers, any corporation, partnership, trust or other entity in which any
officer, director, or any such employee has a substantial interest or is an
officer, director, trustee or partner.

     Subsidiaries.

     Schedule 1 sets forth a complete and accurate list of the Subsidiaries,
including the name of each Subsidiary and its jurisdiction of incorporation,
together with the number of authorized and outstanding shares of each
Subsidiary. Each Subsidiary is directly or indirectly wholly owned by the
Parent. The Parent has good and marketable title to all of the shares it
purports to own of the stock of each Subsidiary, free and clear in each case of
any lien. All such shares have been duly issued and are fully paid and
non-assessable.

     True Copies of Charter and Other Documents.

     The Borrowers have furnished the Agent copies, in each case true and
complete as of the Closing Date, of (a) all charter and other incorporation
documents (together with any amendments thereto) and (b) by-laws (together with
any amendments thereto).

     Disclosure.

     No representation or warranty made by the Borrowers in this Agreement or in
any agreement, instrument, document, certificate, statement or letter furnished
to the Banks or the Agent by or on behalf of or at the request of the Borrowers
in connection with any of the transactions contemplated by the Loan Documents
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements contained therein not misleading
in light of the circumstances in which they are made.

     Permits and Governmental Authority.

     Except as disclosed in Schedule 5.22 hereto, all permits (other than those
the absence of which would not have a material adverse effect on the business,
operations or financial condition of any Borrower) required for the construction
and operation of all landfills or other solid waste facilities currently owned
or operated by the Borrowers have been obtained and remain in full force and
effect and are not subject to any appeals or further proceedings or to any
unsatisfied conditions that may allow material modification or revocation. None
of the Borrowers, nor, to the knowledge of the Borrowers, the holder of such
permits is in violation of any such permits, except for any violation which
would not have a material adverse effect on the business, operations or
financial condition of the Borrowers considered as a whole.

     AFFIRMATIVE COVENANTS OF THE BORROWERS.

     The Borrowers jointly and severally covenant and agree that, so long as any
Loan, any Note, or any Letter of Credit is outstanding or the Banks have any
obligation to make Loans or the Agent has any obligation to issue, extend, or
renew any Letters of Credit hereunder:

     Punctual Payment.

     The Borrowers will duly and punctually pay or cause to be paid the

     with a written statement from such Accountants to the effect that the
     Borrowers are in compliance with the covenants set forth in 8 hereof, and
     that, in making the examination necessary to said Certification, nothing
     has come to the attention of such Accountants that would indicate that any
     Default or Event of Default exists, or, if
<PAGE>
 
     such accountants shall have obtained knowledge of any then existing Default
     or Event of Default they shall disclose in such statement any such Default
     or Event of Default; provided that such Accountants shall not be liable to
     the Banks for failure to obtain knowledge of any Default or Event of
     Default;

          (b) as soon as practicable, but in any event not later than 45 days

     close of business on the date thereof and the results of operations for the

     detail computations evidencing compliance with 7.1, 7.3, 7.9, and 8 hereof,
     provided that if the Borrowers shall at the time of issuance of such
     certificate or at any other time obtain knowledge of any Default or Event
     of Default, the Borrowers shall include in such certificate or otherwise
     deliver forthwith to the Banks a certificate specifying the nature and
     period of existence thereof and what action the Borrowers propose to take
     with respect thereto, and (ii) a certificate in the form of Exhibit D

     Parent; and

          (e) from time to time such other financial data and other information
     (including accountants' management letters) as any Bank or the Agent may
     reasonably request.

     Corporate Existence and Conduct of Business.

     Except where the failure of a Borrower to remain so qualified would not
materially adversely impair the financial condition of such Borrower, each
Borrower will do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence, corporate rights and
franchises; effect and maintain its foreign qualifications, licensing,
domestication or authorization except as terminated by its Board of Directors in
the exercise of its reasonable judgment; shall comply with all applicable laws
and shall not become obligated under any contract or binding arrangement which,
at the time it was entered into would materially adversely impair the financial
condition of such Borrower. Each Borrower will continue to engage primarily in
the businesses now conducted by it and in related businesses.
<PAGE>
 
     Maintenance of Properties.

     The Borrowers will cause all material properties used or useful in the
conduct of their businesses to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Borrowers may be necessary so that the
businesses carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this section shall
prevent any Borrower from discontinuing the operation and maintenance of any of
its properties if such discontinuance is, in the judgment of such Borrower,
desirable in the conduct of its or their business and which does not in the
aggregate materially adversely affect the business of the Borrowers considered
as a whole.

     Insurance.

     The Borrowers will maintain with financially sound and reputable insurance
companies, funds or underwriters' insurance of the kinds, covering the risks
(other than risks arising out of or in any way connected with personal liability
of any officers and directors thereof, which risks may, but shall not be
required by the Banks to be, covered by insurance maintained by the Borrowers)
and in the relative proportionate amounts usually carried by reasonable and
prudent companies conducting businesses similar to that of the Borrowers, but in
no event less than the amounts and coverages set forth in Schedule 6.7 hereto.
In addition, the Borrowers will furnish from time to time, upon the Agent's
request, a summary of the insurance coverage of each of the Borrowers, which
summary shall be in form and substance satisfactory to the Agent and, if
requested by the Agent, will furnish to the Agent copies of the applicable
policies.

     Taxes.

     The Borrowers will each duly pay and discharge, or cause to be paid and
discharged, before the same shall become overdue, all taxes, assessments and
other governmental charges (other than taxes, assessments and other governmental
charges imposed by foreign jurisdictions which in the aggregate are not material
to the business or assets of any Borrower on an individual basis or of the
Borrowers on a consolidated basis) imposed upon it and its real properties,
sales and activities, or any part thereof, or upon the income or profits
therefrom, as well as all claims for labor, materials, or supplies, which if
unpaid might by law become a lien or charge upon any of its property; provided,
however, that any such tax, assessment, charge, levy or claim need not be paid
if the validity or amount thereof shall currently be contested in good faith by
appropriate proceedings and if such Borrower shall have set aside on its books
adequate reserves (as defined by GAAP) with respect thereto; and provided,
further, that such Borrower will pay all such taxes, assessments, charges,
levies or claims forthwith upon the commencement of proceedings to foreclose any
lien which may have attached as security therefor.

     Inspection of Properties, Books, and Contracts.

     The Borrowers shall permit any of the Banks, the Agent or any of their
designated representatives, upon reasonable notice, to visit and inspect any of
the properties of the Borrowers, to examine the books of account of the
Borrowers (including the making of periodic accounts receivable reviews), or
contracts (and to make copies thereof and extracts therefrom), and to discuss
the affairs, finances and accounts of the Borrowers with, and to be advised as
to the same by, their officers, all at such times and intervals as any of the
Banks or the Agent may reasonably request.
<PAGE>
 
     Compliance with Laws, Contracts, Licenses and Permits; Maintenance of
Material Licenses and Permits. 


     Each Borrower will (i) comply with the provisions of its charter documents
and by-laws and all agreements and instruments by which it or any of its
properties may be bound; (ii) comply with all applicable laws and regulations
(including Environmental Laws), decrees, orders, judgments, licenses and
permits, including, without limitation, all environmental permits ("Applicable
Laws"), except where noncompliance with such Applicable Laws would not have a
material adverse effect singly or in the aggregate on the financial condition,
properties or businesses of the Borrowers considered as a whole; (iii) comply in
all material respects with all agreements and instruments by which it or any of
its properties may be bound; (iv) maintain all material operating permits for
all landfills now owned or hereafter acquired; and (v) dispose of hazardous
waste only at licensed disposal facilities operating, to the best of such
Borrower's knowledge after reasonable inquiry, in compliance with Environmental
Laws. If at any time while the Notes, or any Loan or Letter of Credit is
outstanding or any Bank or the Agent has any obligation to make Loans or issue
Letters of Credit hereunder, any authorization, consent, approval, permit or
license from any officer, agency or instrumentality of any government shall
become necessary or required in order that any Borrower may fulfill any of its
obligations hereunder, such Borrower will immediately take or cause to be taken
all reasonable steps within the power of such Borrower to obtain such
authorization, consent, approval, permit or license and furnish the Banks with
evidence thereof.

     Environmental Indemnification.

     The Borrowers covenant and agree that they will indemnify and hold each of
the Banks and the Agent harmless from and against any and all claims, expense,
damage, loss or liability incurred by any of the Banks (including all costs of
legal representation incurred by any of the Banks or the Agent) relating to (a)
any Release or threatened Release of Hazardous Substances on the Real Property;
(b) any violation of any Environmental Laws with respect to conditions at the
Real Property or the operations conducted thereon; or (c) the investigation or
remediation of offsite locations at which the Borrowers, or their predecessors
are alleged to have directly or indirectly Disposed of Hazardous Substances. It
is expressly acknowledged by the Borrowers that notwithstanding anything to the
contrary contained in this Agreement or any of the other Loan Documents this
covenant of indemnification shall survive any foreclosure or any modification,
release or discharge of any or all of the Security Documents, or the payment of
the Loans, or the termination of the obligation to issue Letters of Credit, and
shall inure to the benefit of the Banks, the Agent, and their successors and
assigns.

     Further Assurances.

     The Borrowers will cooperate with the Banks and the Agent and execute such
further instruments and documents as the Banks or the Agent shall reasonably
request to carry out to the Banks' satisfaction the transactions contemplated by
this Agreement.
<PAGE>
 
     Notice of Potential Claims or Litigation.

     The Borrowers shall deliver to the Banks, within 30 days of receipt
thereof, written notice of the initiation of any action, claim, complaint, or
any other notice of dispute or potential litigation (including without
limitation any alleged violation of any Environmental Law), wherein the
potential liability is in excess of $250,000, together with a copy of each such
notice received by any Borrower.

     Notice of Certain Events.

              (a) The Borrowers will provide the Banks with written notice as to
       any cancellation or material change in any insurance of any of the
       Borrowers within ten (10) Business Days after such Borrower's receipt of
       any notice (whether formal or informal) of such cancellation or change by
       any of its insurers.

              (b) The Borrowers will promptly notify the Banks in writing of any
       of the following events:

            (i) upon any Borrower obtaining knowledge of any violation of any
          Environmental Law regarding the Real Property or any Borrower's
          operations which violation, together with all such other violations,
          could result in a fine or penalty of $1,000,000 or more or which would
          reasonably be expected to require expenditures of $1,000,000 or more
          to remedy; (ii) upon any Borrower's obtaining knowledge of any
          potential or known Release, or threat of Release, of any Hazardous
          Substance at, from, or into the Real Property which it reports in
          writing or is required to report in writing to any governmental
          authority and which is material in amount or nature or which could
          materially affect the value of the Real Property; (iii) upon any
          Borrower's receipt of any notice of violation of any Environmental
          Laws or of any Release or threatened Release of Hazardous Substances,
          including a notice or claim of liability or potential responsibility

     CONDITIONS TO ALL LOANS.

     The obligations of the Banks to make any Loan (including without limitation
the obligation of the Agent to issue any Letter of Credit) on and subsequent to
the Closing Date is subject to the following conditions precedent:

     Representations True; No Event of Default.

     Each of the representations and warranties of the Borrowers contained in
this Agreement or in any document or instrument delivered pursuant to or in
connection with this Agreement shall be true as of the date as of which they
were made and shall also be true at and as of the time of the making of the Loan
with the same effect as if made at and as of that time (except to the extent of
changes resulting from transactions contemplated or permitted by this Agreement,
changes disclosed to the Banks in writing and accepted by the Banks, and changes
occurring in the ordinary course of business which singly or in the aggregate
are not materially adverse, and to the extent that such representations and
warranties relate expressly to an earlier date) and no Default or Event of
Default shall have occurred and be continuing.

     Performance; No Event of Default.

     The Borrowers shall have performed and complied with all terms and
conditions herein required to be performed or complied with by them prior to or
at the time of the making of any Loan or the issuance, extension, or renewal of
any Letter of Credit, and at the time of the making of any Loan or the issuance,
extension, or renewal of any Letter of Credit, there shall exist no Event of
Default or condition which would result in an Event of Default upon consummation
of such Loan (including without limitation any amounts to be drawn under a
Letter of Credit). Each request by the Borrowers for a Loan (including without
limitation each request for issuance of a Letter of Credit) subsequent to the
first Loan shall constitute certification by the Borrowers that the conditions
specified in 10.1 and 10.2 will be duly satisfied on the date of such Loan or
Letter of Credit issuance.

     No Legal Impediment.

     No change shall have occurred in any law or regulations thereunder or
interpretations thereof which in the reasonable opinion of the Banks would make
it illegal for the Banks to make Loans or for the Agent to issue, extend, or
renew Letters of Credit hereunder.
<PAGE>
 
     Governmental Regulation.

     The Banks shall have received such statements in substance and form
reasonably satisfactory to the Banks as they shall require for the purpose of

Banks and the Agent as of the date hereof in substance and in form satisfactory
to the Banks and the Agent, including without limitation a Loan and Letter of
Credit Request in the form attached hereto as Exhibit B, and the Banks and the
Agent shall have received all information and such counterpart originals or
certified or other copies of such documents as the Banks and the Agent may
reasonably request.

     COLLATERAL SECURITY.

     The Obligations shall be secured by a perfected security interest (having,
with respect to each category of Collateral, the respective rights and
priorities set forth in the Security Documents) in all of the shares of the
Subsidiaries of the Parent, whether now owned or hereafter acquired, pursuant to
the terms of the Security Documents to which the Borrowers are parties.

     If any of the following events ("Events of Default" or, if the giving of
notice or the lapse of time or both is required, then, prior to such notice
and/or lapse of time, "Defaults") shall occur:

     (a) if the Borrowers shall fail to pay any principal of the Loans when the
same shall become due and payable, whether at the Maturity Date or any
accelerated date of maturity or at any other date fixed for payment;

     (c) if the Borrowers shall fail to comply with the covenants contained in
6.1, 6.3, 6.4, 6.5, 6.7, 6.8, 6.13, 6.14, 6.16, 6.18, 7 or 8 hereof;

     (d) if the Borrowers shall fail to perform any term, covenant or agreement

written notice of such failure has been given to the Borrowers by the Banks, or
if such default cannot reasonably be cured within 30 days, such longer period as
is required to cure such default (not to exceed sixty (60) days), provided that
the Borrowers shall have provided evidence to the Agent of commencing cure
within such 30 day period and thereafter continue diligently to effect such
cure;
<PAGE>
 
     (e) if any representation or warranty contained in this Agreement or in any
document or instrument delivered pursuant to or in connection with this
Agreement shall prove to have been false in any material respect upon the date

period of grace, any and all obligations for borrowed money or any guaranty with
respect thereto in an aggregate amount greater than $1,000,000, or fail to
observe or perform any material term, covenant or agreement contained in any
agreement by which it is bound, evidencing or securing borrowed money in an
aggregate amount greater than $1,000,000 for such period of time as would, or
would have permitted (assuming the giving of appropriate notice if required) the
holder or holders thereof or of any obligations issued thereunder to accelerate
the maturity thereof; or

     (g) if any Borrower makes an assignment for the benefit of creditors, or
admits in writing its inability to pay or generally fails to pay its debts as
they mature or become due, or petitions or applies for the appointment of a
trustee or other custodian, liquidator or receiver of any Borrower or of any
substantial part of the assets of any Borrower or commences any case or other
proceeding relating to any Borrower under any bankruptcy, reorganization,
arrangement, insolvency, readjustment of debt, dissolution or liquidation or
similar law of any jurisdiction, now or hereafter in effect, or takes any action
to authorize or in furtherance of any of the foregoing, or if any such petition
or application is filed or any such case or other proceeding is commenced
against any Borrower and or any Borrower indicates its approval thereof, consent
thereto or acquiescence therein;

     (h) a decree or order is entered appointing any such trustee, custodian,
liquidator or receiver or adjudicating any Borrower bankrupt or insolvent, or
approving a petition in any such case or other proceeding, or a decree or order
for relief is entered in respect of any Borrower in an involuntary case under
federal bankruptcy laws as now or hereafter constituted, and such decree or
order remains in effect for more than sixty (60) days, whether or not
consecutive;

     (i) if there shall remain in force, undischarged, unsatisfied and unstayed,
for more than thirty (30) days, whether or not consecutive, any final judgment
against any Borrower which, with other outstanding final judgments, against the
Borrowers exceeds in the aggregate $500,000 after taking into account any
undisputed insurance coverage;

     (j) any Borrower or any ERISA Affiliate incurs any liability to the PBGC or
a Guaranteed Pension Plan pursuant to Title IV of ERISA in an aggregate amount
exceeding $500,000; any Borrower or any ERISA Affiliate is assessed withdrawal
liability pursuant to Title IV of ERISA by a Multiemployer Plan requiring
aggregate annual payments exceeding $500,000, or any of the following occurs
with respect to a Guaranteed Pension Plan: (i)
<PAGE>
 
an ERISA Reportable Event, or a failure to make a required installment or other
payment (within the meaning of 302(f)(1) of ERISA), provided the Agent
determines in its reasonable discretion that such event (A) could be expected to
result in liability of such Borrower to the PBGC or the Plan in an aggregate
amount exceeding $250,000 and (B) could constitute grounds for the termination
of such Plan by the PBGC, for the appointment by the appropriate United States
District Court of a trustee to administer such Plan or for the imposition of a
lien in favor of the Guaranteed Pension Plan; (ii) the appointment by a United
States District Court of a trustee to administer such Plan; or (iii) the
institution by the PBGC of proceedings to terminate such Plan;

     (k) any of the Subordinated Debt shall be in default or all or any part of

     (l) unless the Majority Banks approve, any person or group of persons
(within the meaning of Section 13 or 14 of the Securities Exchange Act of 1934,
as amended) owning less than 5% of the Borrower's common stock as of the date
hereof shall have acquired beneficial ownership (within the meaning of Rule 13d-
3 promulgated by the Securities and Exchange Commission under said Act) of 40%
or more of the outstanding shares of common stock of any Borrower; or, during
any period of twelve consecutive calendar months, individuals who were directors
of any Borrower on the first day of such period (and individuals whose
nomination to the board was recommended by a majority of such directors) shall
cease to constitute a majority of the board of directors of such Borrower; or

     (m) if any of the Loan Documents shall be canceled, terminated, revoked or
rescinded otherwise than in accordance with the terms thereof or with the
express prior written agreement, consent or approval of the Banks, or any action
at law, suit or in equity or other legal proceeding to cancel, revoke or rescind
any of the Loan Documents shall be commenced by or on behalf of the Borrowers or
any of their respective stockholders, or any court or any other governmental or
regulatory authority or agency of competent jurisdiction shall make a
determination that, or issue a judgment, order, decree or ruling to the effect
that, any one or more of the Loan Documents is illegal, invalid or unenforceable
in accordance with the terms thereof, then, and in any such event, so long as
the same may be continuing, the Agent may, and upon the request of the Majority
Banks shall, by notice in writing to the Borrowers, declare all amounts owing
with respect to this Agreement, the Notes and the other Loan Documents and all
Reimbursement Obligations to be, and they shall thereupon forthwith become,
immediately due and payable without presentment, demand, protest or other notice
of any kind, all of which are hereby expressly waived by the Borrowers; provided
that in the event of any Event of Default specified in 12.1(g) or 12.1(h), all
such amounts shall become immediately due and payable automatically and without
any requirement of notice from the Agent or any Bank. Upon demand by the Banks
after the occurrence of any Event of Default, the Borrowers shall immediately
provide to the Agent cash in an amount equal to the aggregate Maximum Drawing
Amount of all Letters of Credit outstanding, to be held by the Agent as
collateral security for the Obligations.
<PAGE>
 
Termination of Commitments.

If any Event of Default shall occur, or if on any Drawdown Date the conditions
precedent to the making of the Loans to be made on such Drawdown Date or the
issuance of any Letters of Credit to be issued on such date are not satisfied
(except as a consequence of a default on the part of the Banks), the Banks may
by notice to the Borrowers, terminate the unused portion of the Total Commitment
hereunder, and upon such Notice being given, such unused portion of the Total
Commitment hereunder shall terminate immediately and the Banks and the Agent
shall be relieved of all further obligations to make Loans to or issue Letters
of Credit for the account of the Borrowers hereunder provided that if an Event
of Default specified in 12.1(g) or 12.1(h) shall have occurred, such unused
portion of the Total Commitment shall terminate immediately and the Banks and
the Agent shall be relieved of all further obligations to make Loans to or issue
Letters of Credit for the account of the Borrowers without the requirement of
notice from the Banks or the Agent. No termination of any portion of the Total
Commitment hereunder shall relieve the Borrowers of any of their existing
Obligations to the Banks hereunder or elsewhere.

Remedies.

Subject to 14.8, in case any one or more of the Events of Default shall have
occurred and be continuing, and whether or not the Banks shall have accelerated
the maturity of the Loans pursuant to 12.1, each Bank, if owed any amount with
respect to the Loans or the Reimbursement Obligations, may with the consent of
the Majority Banks proceed to protect and enforce its rights by suit in equity,
action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Agreement and the
other Loan Documents or any instrument pursuant to which the Obligations to such
Bank are evidenced, including, without limitation, as permitted by applicable
law the obtaining of the ex parte appointment of a receiver, and, if such amount
shall have become due, by declaration or otherwise, proceed to enforce the
payment thereof or any legal or equitable right of such Bank. No remedy herein
conferred upon any Bank or the Agent or the holder of any Note or purchaser of
any Letter of Credit Participation is intended to be exclusive of any other
remedy and each and every remedy shall be cumulative and shall be in addition to
every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or any other provision of law.

SETOFF.

Regardless of the adequacy of any collateral, during the continuance of an Event
of Default, any deposits or other sums credited by or due from any Bank to the
Borrowers and any securities or other property of the Borrowers in the
possession of such Bank may be applied to or set off against the payment of the
Obligations and any and all other liabilities, direct, or indirect, absolute or
contingent, due or to become due, now existing or hereafter arising, of the
Borrowers to the Banks. Each of the Banks agrees with each other Bank that (a)
if an amount to be set off is to be applied to Indebtedness of the Borrowers to
such Bank, other than Indebtedness evidenced by the Notes held by such Bank or
constituting Reimbursement Obligations owed to such Bank, such amount shall be
applied ratably to such other Indebtedness and to the Indebtedness evidenced by
all such Notes held by such Bank or constituting Reimbursement Obligations owed
to such Bank, and (b) if such Bank shall receive from the Borrowers, whether by
voluntary payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Notes held by, or constituting
Reimbursement Obligations owed to, such Bank by proceedings against the
Borrowers at law or in equity or by proof thereof in bankruptcy, reorganization,
liquidation, receivership or similar proceedings, or otherwise, and shall retain
and apply to the payment of the Note or Notes held by, or Reimbursement
Obligations owed to, such Bank any amount in excess of its ratable portion of
the payments received by all of the Banks with respect to the Notes held by, and
Reimbursement Obligations owed to, all of the Banks, such Bank will make such
disposition and arrangements with the other Banks with respect to such excess,
either by way of distribution, pro tanto assignment of claims, subrogation or
otherwise as shall result in each Bank receiving in respect of the Notes held by
it or Reimbursement Obligations owed it, such Bank's proportionate payment as
contemplated by this Agreement; provided that if all or any part of such excess
payment is thereafter recovered from such Bank, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest.
<PAGE>
 
THE AGENT.

Appointment of Agent, Powers and Immunities. Each Bank hereby irrevocably
appoints and authorizes the Agent to act as its agent hereunder and under the
other Loan Documents. Except as provided in this 14 and in the other Loan
Documents, the Agent shall take action or refrain from acting only upon
instructions of the Banks and no action taken or failure to act without the
consent of the Banks shall be binding on any Bank which has not consented. Each
Bank irrevocably authorizes the Agent to execute the Security Documents and all
other instruments relating thereto and to take such action on behalf of each of
the Banks and to exercise all such powers as are expressly delegated to the
Agent hereunder and in the Security Documents and all related documents,
together with such other powers as are reasonably incidental thereto. It is
agreed that the duties, rights, privileges and immunities of the Agent, in its
capacity as issuer of Letters of Credit hereunder, shall be identical to its
duties, rights, privileges and immunities as a Bank as provided in this 14. The
Agent shall not have any duties or responsibilities or any fiduciary
relationship with any Bank except those expressly set forth in this Agreement.
Neither the Agent nor any of its affiliates shall be responsible to the Banks
for any recitals, statements, representations or warranties made by the
Borrowers or any other Person whether contained herein or otherwise or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement, the other Loan Documents or any other document referred to or
provided for herein or therein or for any failure by the Borrowers or any other
Person to perform its obligations hereunder or thereunder or in respect of the
Notes. The Agent may employ agents and attorneys-in-fact and shall not be
responsible for the negligence or misconduct of any such agents or attorneys-in-
fact selected by it with reasonable care. Neither the Agent nor any of its
directors, officers, employees or agents shall be responsible for any action
taken or omitted to be taken by it or them hereunder or in connection herewith,
except for its or their own gross negligence or willful misconduct. BKB in its
separate capacity as a Bank shall have the same rights and powers hereunder as
any other Bank.

Actions By Agent.

The Agent shall be fully justified in failing or refusing to take any action
under this Agreement as it reasonably deems appropriate unless it shall first
have received such advice or concurrence of the Banks and shall be indemnified
to its reasonable satisfaction by the Banks against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Agent shall in all cases be fully protected in acting, or
in refraining from acting, under this Agreement or any of the Loan Documents in
accordance with a request of the Banks, and such request and any action taken or
failure to act pursuant thereto shall be binding upon the Banks and all future
holders of the Notes or any Letter of Credit Participation.

Indemnification.

Without limiting the obligations of the Borrowers hereunder or under any other
Loan Document, the Banks agree to indemnify the Agent, ratably in accordance
with their respective Commitment Percentages, for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements or any kind or nature whatsoever which may at any time
be imposed on, incurred by or asserted against the Agent in any way relating to
or arising out of this Agreement or any other Loan Document or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or the enforcement of any of the terms hereof or
thereof or of any such other documents; provided that no Bank shall be liable
for any of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the Agent (or any agent thereof).

Reimbursement.

Without limiting the provisions of 14.3, the Banks and the Agent hereby agree
that the Agent shall not be obliged to make available to any Person any sum
which the Agent is expecting to receive for the account of that Person until the
Agent has determined that it has received that sum. The Agent may, however,
disburse funds prior to determining that the sums which the Agent expects to
receive have been finally and unconditionally paid to the Agent, if the Agent
wishes to do so. If and to the extent that the Agent does disburse funds and it
later becomes apparent that the Agent did not then receive a payment in an
amount equal to the sum paid out, then any Person to whom the Agent made the
funds available shall, on demand from the Agent, refund to the Agent the sum
paid to that Person. If, in the opinion of the Agent, the distribution of any
amount received by it in such capacity hereunder or under the Loan Documents
might involve it in liability, it may refrain from making distribution until its
right to make distribution shall have been adjudicated by a court of competent
jurisdiction. If a court of competent jurisdiction shall adjudge that any amount
received and distributed by the Agent is to be repaid, each Person to whom any
such distribution shall have been made shall either repay to the Agent its
proportionate share of the amount so adjudged to be repaid or shall pay over the
same in such manner and to such Persons as shall be determined by such court.
<PAGE>
 
Documents.

The Agent will forward to each Bank, promptly after the Agent's receipt thereof,
a copy of each notice or other document furnished to the Agent for such Bank
hereunder; provided, however, that, notwithstanding the foregoing, the Agent may
furnish to the Banks a monthly summary with respect to Letters of Credit issued
hereunder in lieu of copies of the related Letter of Credit Applications.

Non-Reliance on Agent and Other Banks.

Each Bank represents that it has, independently and without reliance on the
Agent or any other Bank, and based on such documents and information as it has
deemed appropriate, made its own appraisal of the financial condition and
affairs of the Borrowers and decision to enter into this Agreement and the other
Loan Documents and agrees that it will, independently and without reliance upon
the Agent or any other Bank, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own appraisals and
decisions in taking or not taking action under this Agreement or any other Loan
Document. The Agent shall not be required to keep informed as to the performance
or observance by the Borrowers of this Agreement, the other Loan Documents or
any other document referred to or provided for herein or therein or by any other
Person of any other agreement or to make inquiry of, or to inspect the
properties or books of, any Person. Except for notices, reports and other
documents and information expressly required to be furnished to the Banks by the
Agent hereunder, the Agent shall not have any duty or responsibility to provide
any Bank with any credit or other information concerning any person which may
come into the possession of the Agent or any of its affiliates. Each Bank shall
have access to all documents relating to the Agent's performance of its duties
hereunder at such Bank's request. Unless any Bank shall promptly object to any
action taken by the Agent hereunder (other than actions to which the provisions
of 14.8 are applicable and other than actions which constitute gross negligence
or willful misconduct by the Agent), such Bank shall conclusively be presumed to
have approved the same.

Payments.

Payments to Agent.

A payment by the Borrowers to the Agent hereunder or any of the other Loan
Documents for the account of any Bank shall constitute a payment to such Bank.
The Agent agrees promptly to distribute to each Bank such Bank's pro rata share
of payments received by the Agent for the account of the Banks except as
otherwise expressly provided herein or in any of the other Loan Documents.

Distribution by Agent.

If in the opinion of the Agent the distribution of any amount received by it in
such capacity hereunder, under the Notes or under any of the other Loan
Documents might involve it in liability, it may refrain from making distribution
until its right to make distribution shall have been adjudicated by a court of
competent jurisdiction. If a court of competent jurisdiction shall adjudge that
any amount received and distributed by the Agent is to be repaid, each Person to
whom any such distribution shall have been made shall either repay to the Agent
its proportionate share of the amount so adjudged to be repaid or shall pay over
the same in such manner and to such Persons as shall be determined by such
court.
<PAGE>
 
Delinquent Banks.

     (a) Notwithstanding anything to the contrary contained in this
Agreement or any of the other Loan Documents, any Bank that fails (i) to make
available to the Agent its pro rata share of any Loan or to purchase any Letter
of Credit Participation or (ii) to comply with the provisions of 13 with respect
to making dispositions and arrangements with the other Banks, where such Bank's
share of any payment received, whether by setoff or otherwise, is in excess of
its pro rata share of such payments due and payable to all of the Banks, in each
case as, when and to the full extent required by the provisions of this
Agreement, shall be deemed delinquent (a "Delinquent Bank") and shall be deemed
a Delinquent Bank until such time as such delinquency is satisfied. A Delinquent
Bank shall be deemed to have assigned any and all payments due to it from the
Borrower, whether on account of outstanding Loans, unpaid Reimbursement
Obligations, interest, fees or otherwise, to the remaining nondelinquent Banks
for application to, and reduction of, their respective pro rata shares of all
outstanding Loans and unpaid Reimbursement Obligations. The Delinquent Bank
hereby authorizes the Agent to distribute such payments to the nondelinquent
Banks in proportion to their respective pro rata shares of all outstanding Loans
and unpaid Reimbursement Obligations. A Delinquent Bank shall be deemed to have
satisfied in full a delinquency when and if, as a result of application of the
assigned payments to all outstanding Loans and unpaid Reimbursement Obligations
of the nondelinquent Banks, the Banks' respective pro rata shares of all
outstanding Loans and unpaid Reimbursement Obligations have returned to those in
effect immediately prior to such delinquency and without giving effect to the
nonpayment causing such delinquency.

     (b) A Delinquent Bank shall not be entitled to give instructions to the
Agent or to approve, disapprove, consent to or vote on any matters relating to
this Agreement and the other Loan Documents. All amendments, waivers and other
modifications of this Agreement and the other Loan Documents may be made without
regard to a Delinquent Bank and, for purposes of the definition of "Majority
Banks", a Delinquent Bank shall be deemed not to be a Bank.

     (c) Other than as expressly set forth in this 14.7.3., the rights and
obligations of a Delinquent Bank (including the obligation to indemnify the
Agent) and the other parties hereto shall remain unchanged. Nothing in this
14.7.3. shall be deemed to release any Delinquent Bank from its obligations
under this Agreement and the other Loan Documents, shall alter such obligations,
shall operate as a waiver of any default by such Delinquent Bank hereunder, or
shall prejudice any rights which the Borrowers, the Agent or any Bank may have
against such Delinquent Bank as a result of any default by such Delinquent Bank
hereunder. Nothing herein shall be deemed to require a nondelinquent Bank to
advance more than its Commitment Percentage of any Loan or purchase more than
its Commitment Percentage of any Letter of Credit.

     (d) In the event a Delinquent Bank retroactively cures to the reasonable
satisfaction of Agent the breach which caused a Bank to become a Delinquent
Bank, such Delinquent Bank shall no longer be a Delinquent Bank and shall be
treated as a Bank under this Agreement.
<PAGE>
 
Resignation of Agent.

The Agent may resign at any time by giving sixty (60) days prior written notice
thereof to the Banks and the Borrowers. Upon any such resignation, the Banks
shall have the right to appoint a successor Agent with the consent of the
Borrowers, such consent not to be unreasonably withheld. If no successor Agent
shall have been so appointed by the Banks and shall have accepted such
appointment within thirty (30) days after the retiring Agent's giving of notice
of resignation, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a financial institution having a combined
capital and surplus in excess of $150,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation, the provisions of this Agreement shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent. Any new Agent appointed pursuant to this 14.7 shall
immediately issue new Letters of Credit in place of Letters of Credit previously
issued by the Agent (to the extent such Letters of Credit are returned by the
beneficiaries for purposes of such exchange).

Action by the Banks, Consents, Amendments, Waivers, Etc. Except as otherwise
expressly provided in this 14.8, any action to be taken (including the giving of
notice) may be taken or any consent or approval required or permitted by the
Agreement or any other Loan Document to be given by the Banks may be given, and
any term of this Agreement, any other Loan Document or any other instrument,
document or agreement related to this Agreement or the other Loan Documents or
mentioned therein may be amended and the performance or observance by the
Borrowers or any other person of any of the terms thereof and any Default or
Event of Default (as defined in any of the above referenced documents or
instruments) may be waived (either generally or in a particular instance and
either retroactively or prospectively) only with the written consent of the
Majority Banks; provided, however, that no such consent or amendment which
affects the rights, duties or liabilities of the Agent shall be effective
without the written consent of the Agent. Notwithstanding the foregoing, no
amendment, waiver or consent shall, do any of the following unless in writing
and signed by ALL of the Banks (a) increase the principal amount of the Total
Commitment (or subject the Banks to any additional obligations), (b) reduce the
principal of or interest on the Notes (including, without limitation, interest
on overdue amounts) or any fees payable hereunder, (c) postpone any date fixed
for any payment in respect of principal or interest (including, without
limitation, interest on overdue amounts) on the Notes, or any fees payable
hereunder; (d) change the definition of "Majority Banks" or number of Banks
which shall be required for the Banks or any of them to take any action under
the Loan Documents; (e) amend this 14.8; (f) change the Commitment Percentage of
any Bank, except as permitted under 2.2(c) or 19 hereof; or (g) except as
otherwise permitted hereunder, release any Collateral.

EXPENSES.

Whether or not the transactions contemplated herein shall be consummated, the
Borrowers hereby promise to reimburse Agent for all reasonable out-of-pocket
fees and disbursements (including all reasonable attorneys' fees, collateral
evaluation costs and Consulting Engineer's fees), incurred or expended in
connection with the preparation, filing or recording, or interpretation of this
Agreement, the other Loan Documents, or any amendment, modification, approval,
consent or waiver hereof or thereof. The Borrowers further agree to reimburse
the Agent and the Banks for all such fees and disbursements expended in
connection with the enforcement of any Obligations or the satisfaction of any
indebtedness of the Borrowers hereunder or under any of the other Loan
Documents, or in connection with any litigation, proceeding or dispute hereunder
in any way related to the credit hereunder, including, without limitation, the
so-called "workout" thereof after the occurrence of a Default or Event of
Default. The Borrowers will pay any taxes (including any interest and penalties
in respect thereof) other than the Agent's or the Banks' federal and state
income taxes, payable on or with respect to the transactions contemplated by
this Agreement (the Borrowers hereby agreeing to indemnify the Agent and the
Banks with respect thereto).

INDEMNIFICATION.

The Borrowers agree to indemnify and hold harmless the Agent, the Arranger and
the Banks, as well as the Agent's and the Banks' shareholders, directors,
agents, officers, subsidiaries and affiliates, from and against all damages,
losses, settlement payments, obligations, liabilities, claims, suits, penalties,
assessments, citations, directives, demands, judgments, actions or causes of
action, whether statutorily created or under the common law, and reasonable
costs and expenses incurred, suffered, sustained or required to be paid by an
indemnified party by reason of or resulting from the transactions contemplated
hereby, except any of the foregoing which result from the gross negligence or
willful misconduct of the indemnified party. In any investigation, proceeding or
litigation, or the preparation therefor, the Arranger and each Bank shall be
entitled to select its own counsel and, in addition to the foregoing indemnity,
the Borrowers agree to pay promptly the reasonable fees and expenses of such
counsel. In the event of the commencement of any such proceeding or litigation,
the Borrowers shall be entitled to participate in such proceeding or litigation
with counsel of their choice at their expense. The covenants of this 16 shall
survive payment or satisfaction of payment of amounts owing with respect to the
Notes or any other Loan Document.

17.  TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.
                                   
17.1.  Confidentiality.

Each of the Banks and the Agent agrees, on behalf of itself and each of its
affiliates, directors, officers, employees and representatives, to use
reasonable precautions to keep confidential, in accordance with their customary
procedures for handling confidential information of the same nature and in
accordance with safe and sound banking practices, any non-public information
supplied to it by the Borrowers pursuant to this Agreement that is identified by
such Person as being confidential at the time the same is delivered to the Banks
or the Agent, provided that nothing herein shall limit the disclosure of any
such information (a) after such information shall have become public other than
through a violation of this 17, (b) to the extent required by statute, rule,
regulation or judicial process, (c) to counsel for any of the Banks or the
Agent, (d) to bank examiners or any other regulatory authority having
jurisdiction over any Bank or the Agent, or to auditors or accountants, (e) to
the Agent or any Bank, (f) in connection with any litigation to which any one or
more of the Banks or the Agent is a party, or in connection with the enforcement
of rights or remedies hereunder or under any other Loan Document, (g) to a
Subsidiary or affiliate of such Bank as provided in 17.1 or (h) to any assignee
or participant (or prospective assignee or participant) so long as such assignee
or participant agrees to be bound by the provisions of 19.1.

17.2.  Prior Notification.

Unless specifically prohibited by applicable law or court order, each of the
Banks and the Agent shall, ten (10) days prior to disclosure thereof (unless
such time period is impracticable under the circumstances or precluded by law),
use reasonable efforts to notify the Borrowers of any request for disclosure of
any such non public information by any governmental agency or representative
thereof (other than any such request in connection with an examination of the
financial condition of such Bank by such governmental agency) or pursuant to
legal process.

18.  SURVIVAL OF COVENANTS, ETC.

Unless otherwise stated herein, all covenants, agreements, representations and
warranties made herein, in the other Loan Documents or in any documents or other
papers delivered by or on behalf of the Borrowers pursuant hereto shall be
deemed to have been relied upon by the Banks and the Agent, notwithstanding any
investigation heretofore or hereafter made by any of them, and shall survive the
making by the Banks of the Loans and the issuance, extension or renewal of any
Letters of Credit, as herein contemplated, and shall continue in full force and
effect so long as any amount due under this Agreement, any Letter of Credit or
the Notes remains outstanding and unpaid or any Bank has any obligation to make
any Loans or the Agent has any obligation to issue any Letters of Credit
hereunder. All statements contained in any certificate or other paper delivered
by or on behalf of the Borrowers pursuant hereto or in connection with the
transactions contemplated hereby shall constitute representations and warranties
by the Borrowers hereunder.

19.  ASSIGNMENT AND PARTICIPATION.

It is understood and agreed that each Bank shall have the right to assign at any
time all or a portion of its Commitment Percentage and interests in the risk
relating to the Loans, outstanding Letters of Credit, and its Commitment
hereunder in an amount equal to or greater than $5,000,000 (which assignment
shall be of an equal percentage of the Commitment, the Loans and outstanding
Letters of Credit unless otherwise agreed to by the Agent) to additional banks
or other financial institutions with the prior written approval of the Agent
and, if no Default or Event of Default exists, the Borrowers, which approvals
shall not be unreasonably withheld. Any Bank may at any time, and from time to
time, assign to any branch, lending office, or affiliate or such Bank all or any
part of its rights and obligations under the Loan Documents by notice to the
Agent and the Borrower. It is further agreed that each bank or other financial
institution which executes and delivers to the Agent and the Borrowers hereunder
an Assignment and Acceptance substantially in the form of Exhibit E hereto
together with an assignment fee in the amount of $3,500 payable by the assigning
Bank to the Agent, shall, on the date specified in such Assignment and
Acceptance, become a party to this Agreement and the other Loan Documents for
all purposes of this Agreement and the other Loan Documents, and its portion of
the Commitment, the Loans and Letters of Credit shall be as set forth in such
Assignment and Acceptance. The Bank assignor thereunder shall, to the extent
that rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement. Upon the execution and delivery of such
Assignment and Acceptance, (a) the Borrowers shall issue to the bank or other
financial institution a Note in the amount of such bank's or other financial
institution's Commitment dated the date of the assignment or such other date as
may be specified by the Agent and otherwise completed in substantially the form
of Exhibit A and to the extent any assigning Bank has retained a portion of its
obligations hereunder, an appropriate replacement Note to the assigning Bank
reflecting its assignment; (b) the Agent shall distribute to the Borrowers, the
Banks and such bank or financial institution a schedule reflecting such changes;
and (c) this Agreement shall be appropriately amended to reflect (i) the status
of the bank or financial institution as a party hereto and (ii) the status and
rights of the Banks hereunder.

Each Bank shall also have the right to grant participations to one or more banks
or other financial institutions in its Commitment, the Loans and outstanding
Letters of Credit. The documents evidencing any such participation shall limit
such participating bank or financial institutions voting rights with respect to
this Agreement to the matters set forth in 14.8 which require the vote of all
Banks.

Notwithstanding the foregoing, no assignment or participation shall operate
to increase the Commitment hereunder or otherwise alter the substantive terms of
this Agreement, and no Bank which retains a Commitment hereunder shall have a
Commitment of less than $5,000,000, as such amount may be reduced upon
reductions in the Total Commitment pursuant to 2.2 hereof.

Anything contained in this 19 to the contrary notwithstanding, any Bank may
at any time pledge all or any portion of its interest and rights under this
Agreement (including all or any portion of its Notes) to any of the twelve
Federal Reserve Lenders organized under 4 of the Federal Reserve Act, 12 U.S.C.
341. No such pledge or the enforcement thereof shall release the pledgor Bank
from its obligations hereunder or under any of the other Loan Documents.
<PAGE>
 
19.1.  Disclosure.

The Borrowers agree that in addition to disclosures made in accordance with
standard and customary banking practices any Bank may disclose information
obtained by such Bank pursuant to this Agreement to assignees or participants
and potential assignees or participants hereunder; provided that such assignees
or participants or potential assignees or participants shall agree (i) to treat
in confidence such information unless such information becomes public knowledge
other than as a result of the Agent's, any Bank's or any actual or potential
assignee's or participant's breach of its obligation of confidentiality set
forth herein, (ii) not to disclose such information to a third party, except as
required by law or legal process or by a regulatory authority and (iii) not to
make use of such information for purposes of transactions unrelated to such
contemplated assignment or participation.

20.  PARTIES IN INTEREST.

All the terms of this Agreement and the other Loan Documents shall be binding
upon and inure to the benefit of and be enforceable by the respective successors
and assigns of the parties hereto and thereto; provided that no Borrower shall

Banks.

other rights which the Banks or Agent would otherwise have. The captions in this
Agreement are for convenience of reference only and shall not define or limit
the provisions hereof. This Agreement and any amendment hereof may be executed
in several counterparts and by each party on a separate counterpart, each of
which when so executed and delivered shall be an original, but all of which
together shall constitute one instrument. In proving this Agreement it shall not
be necessary to produce or account for more than one such counterpart signed by
the party against whom enforcement is sought.
<PAGE>
 
23.  ENTIRE AGREEMENT, ETC.

The Loan Documents and any other documents executed in connection herewith or
therewith express the entire understanding of the parties with respect to the
transactions contemplated hereby. Neither this Agreement nor any term hereof may
be changed, waived, discharged or terminated, except as provided in 14.8. No
waiver shall extend to or affect any obligation not expressly waived or impair
any right consequent thereon. No course of dealing or omission on the part of
the Agent or any Bank in exercising any right shall operate as a waiver thereof
or otherwise be prejudicial thereto. No notice to or demand upon the Borrowers
shall entitle the Borrowers to other or further notice or demand in similar or
other circumstances.

24.  WAIVER OF JURY TRIAL.

EACH OF THE BORROWERS HEREBY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO
ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS
AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR
OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE OF SUCH RIGHTS AND
OBLIGATIONS. EXCEPT AS PROHIBITED BY LAW, EACH BORROWER HEREBY WAIVES ANY RIGHT
IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THE PRECEDING
SENTENCE ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY
DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. THE BORROWERS (a) CERTIFY
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY BANK OR THE AGENT HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH BANK OR THE AGENT WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (b)
ACKNOWLEDGE THAT THE AGENT AND THE BANKS HAVE BEEN INDUCED TO ENTER INTO THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH IT IS A PARTY BECAUSE OF, AMONG
OTHER THINGS, THE BORROWERS' WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.

25.  GOVERNING LAW.

THIS AGREEMENT AND, EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED THEREIN, EACH OF
THE OTHER LOAN DOCUMENTS ARE CONTRACTS UNDER THE LAWS OF THE COMMONWEALTH OF
MASSACHUSETTS AND SHALL FOR ALL PURPOSES BE CONSTRUED IN ACCORDANCE WITH AND

CONFLICTS OR CHOICE OF LAW). THE BORROWERS CONSENT TO THE JURISDICTION OF ANY OF
THE FEDERAL OR STATE COURTS LOCATED IN THE COMMONWEALTH OF MASSACHUSETTS IN
CONNECTION WITH ANY SUIT TO ENFORCE THE RIGHTS OF ANY BANK OR THE AGENT UNDER
THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.

26.  SEVERABILITY.

provision hereof shall be held invalid or unenforceable in whole or in part in
any jurisdiction, then such invalidity or unenforceability shall affect only
