         account of the Agent at the end of each calendar quarter commencing on

         other notice received from the Borrowers hereunder.

                  (c) If, on or prior to the Borrowing Date of any requested
         Advance, the Total Commitment has not terminated in full and the
         applicable conditions of Section 3 hereof are satisfied, the Banks will
         advance to the Borrower making the request their respective Commitment
         Percentages of the requested Advance by credit to the Borrower's
         specified account with the Agent or by such other means as agreed upon
         by the Borrower and the Agent in immediately available funds not later
         than the close of business on such Borrowing Date.

                  (d) The failure of any Bank to make its pro rata share of any
         Advance shall not relieve any other Bank of its obligation, if any,
         hereunder to make its pro rata share of an Advance on the proposed
         Borrowing Date, but no Bank shall be responsible for the failure of the

   19

                                      -15-

         other Bank to make the part of the Advance to be made by such other
         Bank on the Borrowing Date.

                  (e) The obligations of the Company to repay all amounts
         borrowed by it hereunder, all interest thereon and all fees and other
         amounts payable by it in respect thereto shall be evidenced by this
         Agreement and by individual loan accounts (collectively, the "Loan
         Accounts" and individually, a "Loan Account") maintained by each of the
         Banks, it being the intention of the parties hereto that the Company's
         obligation with respect to its Loan are to be evidenced only as stated
         herein and not by separate promissory notes. Each Bank shall render to
         the Company and the Agent, on or before the fifth Business Day of each
         calendar quarter, a statement of its Loan Account as of the last day of
         the prior calendar quarter, which statement shall, in the absence of
         manifest error, be considered correct and binding upon the Company
         unless the Company notifies such Bank and the Agent to the contrary
         within 45 days from the receipt of such statement; provided that the
         failure of any Bank to render any such statement in a timely fashion
         shall not affect or impair the validity or binding nature of any Loan
         Account.

                  (f) The obligations of each Borrowing Subsidiary to repay all
         amounts borrowed by it under this Agreement, all interest thereon and
         all fees and other amounts payable by it in respect thereto shall be
         evidenced by its promissory notes, substantially in the form of Exhibit
         C hereto, appropriately completed (collectively, the "Notes" and
         individually, a "Note") dated the applicable Borrowing Date and payable
         severally to the order of each of the Banks in a principal amount equal
         to such Bank's Commitment Percentage of the Total Commitment.

         2.7.  Optional Currencies.

                  (a) A Borrower may elect, prior to the Commitment Expiry Date,
         to draw down a portion of the Total Commitment in, or convert Loans
         outstanding to, an Optional Currency (if any), provided that the
         aggregate principal amount of Loans outstanding immediately following
         any such drawdown or conversion shall not exceed the Total Commitment
         then in effect. Amounts proposed to be converted at any one time under
         this Section 2.7 shall not be less than U.S. $500,000 and shall be an
         integral multiple thereof, or the Dollar Equivalent in any Optional
         Currency. In order to exercise the foregoing option a Borrower must
         deliver to the Agent a written notice, subject to any other notice
         requirements under this Agreement, designating the currency into which
         the designated portion of the Borrower's Loan is to be drawn down or,

   20

                                      -16-

         as the case may be, converted, at least five (5) Business Days prior to
         the commencement of the subsequent Interest Period relating to such
         portion of the Borrower's Loan and any such conversion shall be
         effected on such date. If any such notice is not delivered to the Agent
         by such Borrower within the required time, the Borrower shall be deemed
         to have elected that the relevant portion of the principal amount of
         the Borrower's Loan continue to be denominated in the currency in which
         it then currently stands denominated. No Interest Period during which a
         portion of the principal of a Borrower's Loan is to be denominated in
         any Optional Currency shall have an Interest Payment Date which occurs
         after the Commitment Expiry Date.

                  If any Bank determines (which determination shall be
         conclusive), and notifies the Agent on or prior to the second Business
         Day preceding the first day of any Interest Period during which a
         portion of the principal of a Borrower's Loan is to be denominated in
         any Optional Currency, that the Optional Currency is not freely
         transferable and convertible into Dollars or that it will be
         impracticable for such Bank to fund its portion of the Advance in such
         Optional Currency, then the Agent shall so notify the Borrower making
         the election, and that portion of the principal amount of the
         Borrower's Loan shall, notwithstanding any contrary election by such
         Borrower or any other provisions hereof, be denominated in Dollars and
         be in the form of a Base Rate Advance.

                  (b) For all purposes of this Agreement, the amount in one
         currency which shall be equivalent on any particular date to a
         specified amount in another currency shall be that amount (as
         conclusively ascertained by the Agent absent manifest error) in the
         first currency which is or could be purchased by the Agent (in
         accordance with its normal banking practices) with such specified
         amount in the second currency in any interbank foreign currency
         deposits market selected by the Agent in good faith for delivery on
         such date at the spot rate of exchange prevailing on such date.

                  (c) In the event that any portion of the funds available under
         the terms of this Agreement is denominated in one or more Optional
         Currencies, the Dollar Equivalent of such portion of the funds shall be
         calculated pursuant to paragraph (b) above. The amount so determined
         shall then be added to the amount already outstanding in Dollars for
         the purpose of determining the remaining availability of funds under
         Section 2.1 and Section 2.7(a) hereof and any required repayments under
         Section 2.10(c) hereof. Notwithstanding the foregoing, if at any time
         prior to the Commitment Expiry Date, the sum of (a) the aggregate

   21

                                      -17-

         principal amounts outstanding hereunder denominated in Dollars plus (b)
         Dollar Equivalent of the aggregate principal amount outstanding
         hereunder shall exceed the lesser of the Total Commitment or the
         Borrowing Base as a result of fluctuations in respective conversion
         rates, each Borrower shall pay immediately, upon demand made by the
         Agent, all amounts required in order to reduce the Loans outstanding to
         the lesser of the Total Commitment and the Borrowing Base.

         2.8.  Interest Payable on the Loans.

                  (a) With respect to any Advance or Term Loan denominated in
         Dollars, the rate of interest which shall be jointly and severally
         payable by the Borrowers on the unpaid principal outstanding to the
         Borrowers shall be the annual percentage rate of interest determined by
         the Agent to be the sum of (i) the applicable Margin in effect plus
         (ii) the Base Rate, or if the Borrower has so elected pursuant to this
         paragraph (a), the Eurodollar or CD Rate relating to the Interest
         Period with respect to any such Advance or Term Loan. Any Borrower may
         elect, prior to the Commitment Expiry Date (A) to draw down a portion
         of the funds available under this Agreement in Dollars upon which
         interest will accrue based on the Eurodollar Rate or the CD Rate or (B)
         to convert any Base Rate Advance or Base Rate Loan, CD Rate Advance or
         CD Rate Loan or Eurodollar Rate Advance or Eurodollar Rate Loan
         denominated in Dollars to or from any other type of Advance or Term
         Loan, on the last day of the Interest Period with respect to the
         Advance or Term Loan to be converted. In order to exercise the
         foregoing option, a Borrower must deliver to the Agent a written notice
         subject to any other notice requirements under this Agreement
         designating the election of the basis on which the interest rate will
         be determined at least five (5) Business Days prior to the commencement
         of the Interest Period relating to such portion of the Borrower's Loan
         on which such conversion is to occur.

                  (b) The rate of interest which shall be payable by a Borrower
         on any portion of the principal of the Loan extended to such Borrower
         which is denominated in an Optional Currency for the time being, and is
         outstanding during each Interest Period relating thereto, shall be the
         annual percentage rate of interest determined by the Agent to be the
         sum of (i) the applicable Margin in effect plus (ii) the Eurodollar
         Rate relating to such Interest Period.

                  (c)  Interest  shall be payable  jointly and  severally by the
         Borrower,  and the  Borrowers  hereby  absolutely  and  unconditionally

   22

                                      -18-

         jointly and severally promises to pay, to the Agent for the account of
         the Banks in arrears in Dollars, or, as the case may be, in the
         Optional Currency in which that portion of the principal amount of the
         Loan extended to such Borrower, in respect of which payment is made, is
         denominated (i) with respect to CD Rate Advances or CD Rate Loans or
         Eurodollar Rate Advances or Eurodollar Rate Loans, on each Interest
         Payment Date, provided, however, that if the duration of any such
         Interest Period is longer than three months, the Borrower shall pay the
         accrued interest on the last Business Day of each successive three
         month period and (ii) with respect to Base Rate Advances or Base Rate
         Loans, quarterly on the last day of each calendar quarter hereafter,
         and on any earlier date when a Base Rate Advance or Base Rate Loan is
         converted to a CD Rate Advance or CD Rate Loan or Eurodollar Rate
         Advance or Eurodollar Rate Loan.

                  (d) Each determination of any interest rate by the Agent with
         respect to any Loan shall be conclusive in the absence of manifest
         error. Base Rate interest rates shall change as the Base Rate shall
         change, and any change in the interest rates shall become effective as
         of the beginning of the day during which such change in the Base Rate
         occurs.

                  (e) Overdue principal and, to the extent permitted by
         applicable law, overdue interest and other amounts overdue under any
         provision of this Agreement shall bear interest at the rate per annum
         determined by the Agent to be two per cent (2%) above (i) with respect
         to Loans denominated in an Optional Currency, the rate then applicable
         to the relevant Advances for funding periods not greater than six
         months established by the Agent, in its discretion, from time to time
         and (ii) with respect to Loans denominated in Dollars, the Base Rate.
         Such interest on overdue principal and overdue interest and other
         amounts overdue shall be payable on demand and shall continue to accrue
         from the due date of such principal, interest or amounts and shall be
         compounded monthly until the obligation of the Borrower in respect of
         the payment thereof is discharged (whether before or after judgment).

         2.9.  Alternative Interest Rates.

                  (a) Except as otherwise provided in this Agreement, if on any
         Rate-fixing Day on which the interest rate with respect to any Advance
         or Term Loan is to be based on the Eurodollar Rate, the Agent shall
         determine that it is unable to quote the Eurodollar Rate, or any Bank
         shall determine that such Bank is unable to or it is impracticable for
         it to fund the Advance or Term Loan for the requested Interest Period,
         the Borrower shall be deemed to have elected that the Advances or Term

   23

                                      -19-

         Loans be denominated in Dollars as Base Rate Advances.

                  (b) If any Bank shall in good faith determine that, by reason
         of circumstances affecting the market for certificates of deposit
         maintained by New York dealers of recognized standing, adequate and
         reasonable means do not exist for such Bank to obtain bids for the
         purchase of certificates of deposit on the first day of an applicable
         Interest Period then (a) such Bank shall so notify the Agent and the
         Agent shall notify the Borrower and the Banks, and (b) any Advances or
         Term Loans which are the subject of such request by the Borrower shall
         be Base Rate Advances.

         2.10.  Repayments and Prepayments of the Loans, etc.

                  (a) On and as of the Commitment Expiry Date, the principal
         amount of the Loans then outstanding (the "Total Loan") shall be held
         by the Banks on a pro rata basis in accordance with their respective
         Commitment Percentages. Provided that no Event of Default has occurred
         and is continuing, the Total Loan shall be payable in installments over
         a term of two years as set forth in this paragraph (a). The Borrowers
         jointly and severally hereby absolutely and unconditionally promise to
         pay to the Agent for the accounts of the Banks ratably according to the
         then outstanding principal amount of the Total Loan, on the last day of
         April, July, October and January commencing on April 30, 1999, and
         ending on January 31, 2001 (each of such 8 dates hereinafter referred
         to as a "Repayment Date"), and there shall become absolutely due and
         payable on each Repayment Date, a fixed installment of principal in an
         amount equal to one-eighth of the Total Loan. All such repayments shall
         be made in the currency in which the Loan to be repaid or any portions
         thereof is denominated. The Borrowers jointly and severally hereby
         absolutely and unconditionally agree to pay to the Agent for the
         accounts of the Banks ratably according to the then outstanding
         principal amount of the Total Loan, on January 31, 2001 (the "Final
         Repayment Date"), and there shall become absolutely due and payable on
         the Final Repayment Date, the entire unpaid principal amount of the
         Total Loan outstanding on such date. In addition, the Borrowers each
         agree to execute and deliver to each Bank prior to the close of
         business on the Commitment Expiry Date, a term note (the "Term Note")
         containing the terms set forth herein, which Term Note shall be in form
         and substance satisfactory to the Banks.

                  (b) Each Borrower may, pursuant to this paragraph (b), elect
         to prepay the principal of any Base Rate Advance or Base Rate Loan
         outstanding at any time in full or in part without premium or penalty,

   24

                                      -20-

         or to prepay the principal of any Eurodollar Rate Advance or Eurodollar
         Rate Loan or CD Rate Advance or CD Rate Loan outstanding in full or in
         part without premium or penalty on the Interest Payment Date of any
         Interest Period relating to the unpaid principal of such Eurodollar
         Rate Advance or Eurodollar Rate Loan or CD Rate Advance or CD Rate Loan
         to be prepaid, provided that the amount of any prepayment of the unpaid
         principal of any Advance pursuant to this paragraph (b) shall be in a
         principal amount of such Advance or not less than $500,000 or the
         equivalent thereof in the Optional Currency in which that portion of
         the principal amount of the Advance in respect of which the payment is
         to be made is denominated. Any and all amounts of the Term Loans
         prepaid pursuant to this Section 2.10(b) shall be applied to the unpaid
         principal amount of such Borrower's Total Loan in the inverse order of
         maturity. Amounts prepaid pursuant to this paragraph (b) may, subject
         to the terms and conditions of this Agreement, be reborrowed on or
         before the Commitment Expiry Date.

                  (c) If at any time (i) on or prior to the Commitment Expiry
         Date the sum of (1) the aggregate principal amounts outstanding
         hereunder denominated in Dollars plus (2) the Dollar Equivalent of the
         aggregate principal amount outstanding hereunder shall exceed the
         lesser of (x) the Total Commitment and (y) the Borrowing Base (whether
         as a result of fluctuations in the currency rates or otherwise), there
         shall become absolutely due and payable, and one or more Borrowers, as
         determined by the Company, hereby promises to pay to the Agent all
         amounts required in order to reduce the principal amount outstanding to
         the lesser of the Total Commitment and the Borrowing Base, or the
         equivalent thereof in one or more Optional Currencies; and (ii) after
         the Commitment Expiry Date the sum of (1) the aggregate principal
         amounts outstanding hereunder denominated in Dollars plus (2) the
         Dollar Equivalent of the aggregate principal amount outstanding
         hereunder shall exceed (whether as a result of fluctuations in the
         currency rates or otherwise) the permitted aggregate outstanding
         principal amount of the Term Loans determined in accordance with
         ss.2.10(a), there shall become absolutely due and payable, and one or
         more Borrowers, as determined by the Company, hereby promises to pay to
         the Agent all amounts required in order to reduce the principal amount
         outstanding to the principal amount permitted to be outstanding
         pursuant to ss.2.10(a).

                  (d) Upon each repayment or prepayment of any principal of any
         Advance or Term Loans pursuant to any of the provisions of this
         Agreement, each Borrower hereby absolutely and unconditionally promises

   25

                                      -21-

         to pay to the Agent for the account of each Bank and there shall become
         absolutely due and payable on the date of each such repayment or
         prepayment, all of the unpaid interest accrued to such date on the
         amount of the principal of the Advance or Term Loans being repaid or
         prepaid on such date, together with all, if any, other sums then due
         and payable hereunder in respect of the principal of the Advance or
         Term Loans being repaid or prepaid on such date, including, but not
         limited to, any sums payable in accordance with Section 2.14 hereof
         which have been ascertained on or prior to the date of such repayment
         or prepayment. Whenever any interest on and any principal of an Advance
         or Term Loans is paid simultaneously hereunder, the whole amount paid
         shall be applied first to interest then due and payable.

                  (e) Each repayment or prepayment of principal of less than the
         entire unpaid principal amount owed by all of the Borrowers under this
         Agreement and the Notes shall be allocated among the Banks in
         proportion, as nearly as practicable, to the respective unpaid
         principal debit balances of the Banks' Loan Accounts and/or principal
         amounts of the Banks' Notes of the Borrowing Subsidiary which is the
         obligor thereunder, with adjustments to the extent practical to
         equalize any prior payments not exactly in proportion.

         2.11.  Payments and Computations.

                  (a) Each payment payable by a Borrower hereunder (i) if
         denominated in Dollars shall be made to the Agent at its head office at
         100 Federal Street, Boston, Massachusetts, in immediately available
         funds, or, (ii) if denominated in any Optional Currency shall be made
         in such immediately available funds as shall then be customary for
         settlement at the place of payment of international transactions in
         such Optional Currency, for the account of the Agent at a depository
         designated by the Agent. Each Borrower authorizes the Agent and the
         Banks to charge any of its respective accounts, other than payroll
         accounts, with the Agent or the Banks for the amount of any payment due
         hereunder.

                  (b) If any sum would, but for the provisions of this Section
         2.11(b), become due and payable hereunder on a day which is not a
         Business Day, then such sum shall become due and payable on either the
         Business Day next preceding or the Business Day next succeeding the day
         on which such sum would otherwise have become due and payable
         hereunder, such Business Day to be selected (which selection shall be
         conclusive and binding on each Borrower) by the Agent in accordance

   26

                                      -22-

         with the then current banking practice in the relevant interbank
         Eurodollar market or Boston, as the case may be and interest and
         commitment fees hereunder shall be adjusted accordingly.

                  (c) All computations of interest and commitment fees payable
         hereunder shall be made by the Agent on the basis of actual number of
         days elapsed and on a 360-day year.

                  (d) Each determination by the Agent of an amount of interest
         or commitment fee payable by the Borrower hereunder shall, save for
         manifest error, be conclusive and binding upon the Borrower.

                  (e) Promptly upon receipt of all payments under this Agreement
         or the Notes, the Agent shall pay to each of the Banks its pro rata
         share thereof.

         2.12. Payments to be Free of Deductions. All payments by the Borrowers
under this Agreement shall be made without set-off 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 country or any political
subdivision thereof or taxing or other authority therein unless a Borrower is
compelled by law to make such deduction or withholding. If any such obligation
is imposed upon a Borrower with respect to any amount payable by it hereunder,
the Borrower will pay to the Agent for the account of each Bank, on the date on
which the said amount becomes due and payable hereunder, such additional amount
as shall be necessary to enable each Bank to receive the same net amount which
it would have received on such due date had no such obligation been imposed upon
the Borrower. Each Borrower will deliver promptly to the Agent certificates or
other valid vouchers for all taxes or other charges deducted from or paid with
respect to payments made by such Borrower hereunder.

         2.13.  Additional Costs, Changes in Circumstances, etc.

                  (a) Anything hereinbefore to the contrary notwithstanding, if
         any present or future applicable law (which expression, as used in this
         Agreement, includes statutes and 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 heretofore or hereafter made
         upon or otherwise issued to the Agent or any Bank by any central bank
         or other fiscal, monetary or other authority, whether or not having the

   27

                                      -23-

         force of law) shall (i) subject the Agent or any Bank to any tax, levy,
         impost, duty, charge, fee, deduction or withholding of any nature with
         respect to this Agreement, the amount of such Banks' Commitment, or the
         payment to the Agent or either Bank of any amounts due to it hereunder,
         or (ii) materially change the basis of taxation of payments to the
         Agent or any Bank of the principal or the interest on or any other
         amounts payable to the Agent or any Bank hereunder, or (iii) impose or
         increase or render applicable any special or supplemental special
         deposit or reserve or similar requirements (whether or not having the
         force of law) against assets held by, or deposits in or for the account
         of, or any eligible liabilities of, or loans by an office of the Agent
         or either Bank, or (iv) impose on the Agent or any Bank any other
         condition or requirement with respect to this Agreement, the
         Commitments, and the result of any of the foregoing is (A) to increase
         the cost to any Bank of making, funding or maintaining all or any part
         of the Loans, or (B) to reduce the amount of principal, interest or
         other amount payable to any Bank hereunder, or (C) to require the Agent
         or any Bank 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 the Agent or any Bank from any
         Borrower hereunder, then, and in each such case, such Borrower will,
         upon demand made by the Agent, pay to the Agent for its account or for
         the account of any such Bank, as the case may be, such additional
         amounts as will be sufficient to compensate them for such additional
         cost, reduction, payment or foregone interest or other sum, provided
         that the foregoing provisions of this sentence shall not apply in the
         case of any additional cost, reduction, payment or foregone interest or
         other sum resulting from any taxes charged upon or by reference to the
         overall net income, profits or gains of the Agent or any Bank.

                  (b) If any Bank shall determine that any change in applicable
         law shall make it unlawful for such Bank to comply with or to maintain
         its obligations to fund Eurodollar Rate Advances or Eurodollar Rate
         Loans or Advances or Term Loans in any Optional Currency hereunder in
         the relevant interbank market, then such Bank shall notify the Agent
         and the Agent shall notify the requesting Borrower of such
         determination in writing. If the Agent so notifies such Borrower, then
         (i) the Commitment and obligations to fund the Advances as Eurodollar
         Rate Advances or Eurodollar Rate Loans or in such Optional Currency or
         Currencies, as the case may be, shall terminate in full on and as of
         the date of such notice, and (ii) such Advances or Term Loans shall on
         the Interest Payment Date of any Interest Period which is current when

   28

                                      -24-

         the Borrower is so notified be converted to Base Rate  Advances or Base
         Rate Loans.

         2.14. Indemnification for Losses. Each Borrower will, on demand by any
Bank at any time, indemnify such Bank against any losses, costs or expenses
which such Bank may at any time incur as a consequence of (a) the breach by such
Borrower of its obligations to borrow a CD Rate Advance or Eurodollar Rate
Advance on the Borrowing Date thereof, (b) the failure by such Borrower to pay,
punctually on the due date thereof, any amount payable hereunder, (c) the
accelerated payment of any obligations of such Borrower hereunder as the result
of an Event of Default, or (d) the repayment or prepayment of any principal
under a CD Rate Advance, CD Rate Loan, Eurodollar Rate Advance or Eurodollar
Rate Loan on a date other than an Interest Payment Date of an Interest Period
relating to such principal, such losses, costs or expenses to include, but not
to be limited to, (i) any costs incurred by such Bank in carrying funds which
were to have been borrowed by such Borrower or in carrying funds to cover the
amount of any overdue principal of or overdue interest on any Advance or Term
Loan, (ii) any interest payable by such Bank to lenders of the funds borrowed by
the Bank in order to carry the funds referred to in the immediately preceding
sub-clause (i), and (iii) any losses (including losses of anticipated profit)
incurred by such Bank in liquidating or re-employing funds acquired from third
parties to effect or maintain all or any part of any Advance or any portion
thereof.

         2.15. Increased Capital Requirements. If (i) any change in law or any
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 or (ii) the implementation
of any risk-based capital guideline or requirement (whether or not having the
force of law) heretofore or hereafter issued by any government or governmental
or supervisory authority, affects the amount of capital required or expected to
be maintained by any of the Banks or any corporation controlling any of the
Banks and any Bank determines that the amount of capital required is increased
by or based upon the existence of the credit facility established hereunder or
any Loans made pursuant hereto then such Bank may notify the Company and the
Agent of such fact. To the extent that the costs of such increased capital
requirements are not reflected in the interest rates charged on the Loans, the
Company and the Bank shall thereafter attempt to negotiate in good faith an
adjustment to the compensation payable hereunder which will adequately
compensate such Bank in light of these circumstances. If the Company and the
Bank are unable to agree to such adjustment within thirty days of the day on
which the Company receives such notice, then commencing on the date of such
notice (but not earlier than the effective date of any such change), the fees
payable hereunder shall increase by an amount which will, in such Bank's
reasonable determination, provide adequate compensation (such compensation to
include, without limitation, an amount equal to any reduction of the rate of
return on assets or equity of such Bank allocable by such Bank to its portion of

   29

                                      -25-

the Total Commitment or the Loans to a level below that which such Bank or any
controlling corporation could have achieved but for such requirements).

         2.16. HLT Classification. In the event that after the date hereof the
Loan or the Total Commitment hereunder are classified on the Agent's books as a
"highly leveraged transaction" (an "HLT Classification") by the Agent or by any
governmental authority, central bank or comparable agency having jurisdiction
over the Agent, then the Agent shall promptly give notice of such HLT
Classification to the Company and the Banks whereupon the Agent, the Banks and
the Company shall commence negotiations in good faith to agree on a revised
commitment fee, interest rates and/or margins hereunder reflecting such HLT
Classification. In the event that the parties hereto fail to agree on such
revised commitment fee, interest rates and/or margins within 30 days of the
notice given by the Agent, then the Agent shall (i) if requested by the Majority
Banks, by five Business Days' notice to the Borrowers terminate the unused
portions of the Total Commitment and they shall thereupon terminate, and (ii) if
requested by the Majority Banks, by five Business Days' notice to the Borrowers
declare all outstanding Loans (together with accrued interest thereon and any
other amounts payable hereunder) to be, and all such amounts shall thereupon
become, absolutely and immediately due and payable without presentment, demand,
protest or other notice of any kind, all of which are hereby waived by each
Borrower. Each of the Borrowers hereby absolutely and unconditionally agrees to
pay to the Agent for the accounts of the Banks on the date of any such
acceleration all amounts payable by it hereunder.

                        SECTION 3. CONDITIONS OF LENDING.

         3.1. Conditions Precedent to Each Advance. The effectiveness of this
Agreement and the obligations of the Banks to make any Advance or a Term Loan

         officer of the Company and if the Borrower is a Borrowing Subsidiary,
         an individual having comparable authority to any of such officers,
         which request without more will constitute certification by such
         officers as to the matters set forth in paragraphs (c), (d), (f) and
         (h) below;

                  (b) The Agent shall have received duly certified copies of all

         time of the making of the Advance with the same effect as if made at

         transactions contemplated by this Agreement 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 Event of Default
         or condition which with notice or the passage of time or both would
         constitute an Event of Default shall exist;

   31

                                      -27-

                  (g) All fees, and all expenses and other amounts due and

         Advances or converting to Term Loans.

         3.2.     Conditions Precedent to First Advance.

                  Company. The Agent and the Banks may rely conclusively on such
                  certification until the Agent receives notice in writing to
                  the contrary from the Company; and

                           (ii) The Agent shall have received an opinion
                  addressed to the Banks from Testa, Hurwitz & Thibeault,

   32

                                      -28-

                  and delivered to the Agent a duly executed Note of such
                  Borrowing Subsidiary.

                   SECTION 4. REPRESENTATIONS AND WARRANTIES.

         4.1.     Representations and Warranties of the Company.  The Company
represents and warrants to the Banks that:

         4.1.1. Organization, Good Standing, Authority, etc. The Company and
each Subsidiary (a) is a corporation duly organized, existing and in good
standing under the laws of the jurisdiction of its incorporation, (b) has all
requisite corporate power to own its property and conduct its business as now
conducted and as presently contemplated and (c) to the best of the Company's
knowledge, is duly qualified to do business and in good standing as a foreign
corporation in each jurisdiction where the nature of its properties or its
business requires such qualification except where the failure to so qualify will
not have a materially adverse effect on the Company and its Subsidiaries. The
execution, delivery and performance of this Agreement and the transactions
contemplated hereby are within the corporate authority of the Company, have been
authorized by proper corporate proceedings and do not and will not contravene
any provisions of its charter, other incorporation papers, by-laws or any stock
provision or any amendment thereof or, to the best of the Company's knowledge,
any provisions of law or of any indenture, agreement, instrument or undertaking
binding upon the Company or any Subsidiary. The execution, delivery and
performance of this Agreement by the Company will result in valid and legally
binding obligations of the Company, enforceable in accordance with their
respective terms, except as limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting generally the
enforcement of creditor's rights.

         4.1.2. Governmental Approvals. No approval or consent of, or filing
with, any governmental agency or authority is required to make valid and legally
binding the execution, delivery and performance of this Agreement by the Company
and consummation of the transactions between the parties hereto contemplated
hereby by the Company.

         4.1.3.  Subsidiaries.  Attached  hereto as Schedule 4.1.3 is a schedule
which  correctly  identifies  all  present  Subsidiaries.  All of the issued and

   33

                                      -29-

outstanding shares of stock of each Subsidiary have been validly issued and are
fully paid and non-assessable and, except for directors' qualifying shares and
as otherwise noted on Schedule 4.1.3, are owned by the Company or a Subsidiary
free and clear of any mortgage, pledge, lien, encumbrance, charge or restriction
on transfer. No rights to subscribe to additional shares of stock of any
Subsidiary have been granted.

         4.1.4. Compliance with Other Instruments. Neither the Company nor any
Subsidiary is in material default under any provisions of its charter, other
incorporation papers, by-laws or stock provisions or any amendment thereof or of
any indenture or agreement or of any order, regulation, ruling or requirement of
a court or public body or authority by which it is bound.

         4.1.5. Litigation. Except as disclosed in Schedule 4.1.5 attached
hereto, no action, suit, investigation or proceeding is pending or known to be
threatened against the Company or any Subsidiary before any court or
administrative agency which, if adversely determined, would materially impair
the ability of the Borrower and its Subsidiaries to carry on their consolidated
business substantially as now conducted or would materially adversely affect the
consolidated financial condition of the Borrower and its Subsidiaries.

         4.1.6. No Adverse Contracts, etc. Neither the Company nor any
Subsidiary is subject to any provision of its charter, other incorporation
papers, by-laws or stock provisions or any amendment thereof or a party to or
otherwise bound by any indenture or agreement or bound by any order, regulation,
ruling or requirement of a court or public body or authority which will, under
current or foreseeable conditions, materially adversely affect its normal
operations or impair its financial condition or prospects.

         4.1.7. Financial Statements. The Company has furnished to the Bank a
consolidated balance sheet as at December 31, 1994 and related consolidated
statements of income (loss), changes in stockholders' equity and cash flows of
the Company and its Subsidiaries for the fiscal year then ended, certified by
Coopers & Lybrand, independent accountants. The balance sheet and statements
described above have been prepared in conformity with generally accepted
accounting principles applied on a consistent basis throughout the periods
specified and present fairly in all material respects the financial position of
the Company and its Subsidiaries as at the date thereof.

         4.1.8.  Changes.  Since December 31, 1994,  there has been no change in
the assets, liabilities, financial condition  or  business of the Company or any
Subsidiary,  other than changes the effect of which has not been in any case, or
in the aggregate, materially adverse.

         4.1.9.   Business.  The  Company  and  each  Subsidiary  has  good  and
marketable  title to its  properties and assets,  including such  properties and

   34

                                      -30-

assets as are reflected in the consolidated balance sheet referred to in Section
4.1.7 hereof (except such assets as have been disposed of in the ordinary course
of business subsequent to the date thereof) subject to no security interests,
except as is permitted by Section 6.2. The Company and each Subsidiary enjoys
peaceful and undisturbed possession under all leases of real or personal
property of which it is lessee, none of which contains any unusual or burdensome
provision which will materially adversely affect or impair the operation of the
Company or any Subsidiary, and all such leases are valid and subsisting and in
full force and effect. To the best of the Company's knowledge, the Company and
each Subsidiary owns or possesses the right to use all the franchises, rights
and licenses, necessary for the conduct of its business as now conducted and as
proposed to be conducted, without any known conflict with the rights of others.

         4.1.10. Taxes. The Company and its Subsidiaries have filed all federal,
state and local tax returns which are required to be filed, except where the
time to file has been extended, and all taxes, assessments and other
governmental charges due from the Company and its Subsidiaries are not
delinquent. All deficiencies finally resulting from examinations of any such
returns by the respective taxing authorities have been discharged or provided
for. To the best of their knowledge, the Company and its Subsidiaries have
adequately provided for the payment of all federal, state and local taxes for
the years that have not been audited by the respective tax authorities.

         4.1.11.  Loan as Senior Indebtedness. The Indebtedness hereunder
evidenced by this Agreement will  constitute  "Senior  Indebtedness"  or "Senior
Debt"  in  any  instrument   evidencing   Indebtedness   which  purports  to  be
Subordinated Indebtedness.

         4.1.12.  No Defaults.  No event has occurred  and is  continuing  and
no condition exists which constitutes or which after notice or lapse of time, or

both, would constitute an Event of Default.

         4.1.13. Regulation U. The Company and each of its Subsidiaries is not
engaged in the business of owning or carrying margin stock (within the meaning
of Regulation U of the Board of Governors of the Federal Reserve System), and no
part of the proceeds of any Loan or Advance will be used to purchase or carry
any margin stock or to extend credit to others for the purpose of purchasing and
carrying any margin stock.

         4.1.14. Pension Plans. The funding of any pension plan of the Company
and its Subsidiaries, or any of them, the benefits under which are guaranteed in
whole or in part by the Pension Benefit Guaranty Corporation, complies with the
minimum funding standards of Section 412 of the Internal Revenue Code of 1954,
as amended.

         4.1.15. Investment Company; Public Utility Holding Company. Neither the
Company nor any Subsidiary is an "investment  company" or a "company controlled"

   35

                                      -31-

by an "investment company" or an "affiliate" of an "investment company" within
the meaning of the Investment Company Act of 1940, as amended. Neither the
Company nor any Subsidiary is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company" or of a
"subsidiary company" of a "holding company", as such terms are defined in the
Public Utility Holding Company Act of 1935, as amended.

         4.1.16.  Environmental Compliance.  Except as set forth in Schedule
4.1.16 hereto,

                  (a) none of the Company, its Subsidiaries or any operator of
         its Property is in violation, or to the Company's knowledge alleged
         violation, of any Environmental Laws, which violation would have a
         material adverse effect on the business, assets or financial condition
         of any of the Borrowers or of the Company and its Subsidiaries taken as
         a whole.

                  (b) none of the Company or its Subsidiaries has received
         notice that it is a potential responsible party under any Environmental
         Law under circumstances which will, under current or foreseeable
         conditions, have a material adverse effect on the business, assets or
         financial condition of any of the Borrowers or of the Company and its
         Subsidiaries taken as a whole.

         4.2.  Representations  and  Warranties  of Each  Borrowing  Subsidiary.
Each Borrowing  Subsidiary  shall be deemed by the execution and delivery of its
election to become a Borrower to have  represented and warranted to the Banks as
of the date thereof as follows:

         4.2.1. Organization, Good Standing, Authority etc. It (a) is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation, (b) has all requisite corporate power
to own its property and conduct its business as now conducted and as currently
contemplated, and (c) to the best of its knowledge, is duly qualified to do
business and in good standing as a foreign corporation in each jurisdiction
where the nature of its property or business requires such qualification except
where the failure to so qualify will not have a materially adverse effect on it.
The execution, delivery and performance of the election to become a Borrower and
its Note, and the performance of its Note and the provisions of the Agreement
applicable to it are within the corporate authority of the Borrowing Subsidiary,
have been duly authorized by all necessary corporate proceedings, and do not and
will not contravene any provisions of its charter, other incorporation papers,
by-laws or any stock provision or any amendment thereof, or, to the best of its
knowledge, any provisions of law or any indenture, agreement, instrument or

         the Company and its Subsidiaries taken as a whole; or (D) upon the
         Company's obtaining knowledge that any expense or loss has been

         a lien may be imposed on the Property under circumstances which will,

         and against any and all claims which allege that the actions or
         transactions of the Agent and the Banks undertaken in conformity with
         this Agreement create any liability under the Environmental Laws,
         provided that the Agent or the Bank, as the case may be, furnish prompt
         notice of the claim and permits the Company to conduct the defense
         against, and approve any settlement for, such claim. The Agent or any
         Bank will be entitled to participate in such defense with counsel of

date of this Agreement, as lessee or guarantor or other surety, with respect to
any lease of real or personal property, whether now owned or hereafter acquired,
(a) which is to be sold or transferred by the Company or a Subsidiary to any
Person, or (b) which the Company or a Subsidiary intends to use for
substantially the same purpose as any other property which has been or is to be
sold or transferred by the Company or a Subsidiary to any Person in connection
with such lease (either of the foregoing transactions being hereinafter referred
to as a "Leaseback"), except Leasebacks involving property, the aggregate value
of which for all Leasebacks after December 31, 1990 is not in excess of 10% of
Consolidated Tangible Net Worth on the date of any such Leaseback. For purposes
of this section the value of property shall be the greater of the fair market
value of the property or the book value of the property prior to the transfer as
determined in accordance with generally accepted accounting principles.

                              SECTION 7. GUARANTY.

         7.1. Guaranty. For value received and hereby acknowledged and as an
inducement to the Banks to make Loans or Advances to the Borrowing Subsidiaries,
the Company hereby unconditionally and irrevocably guarantees: (i) the full
punctual payment when due, whether at stated maturity, by acceleration or
otherwise, of all obligations of each Borrowing Subsidiary now or hereafter
existing hereunder and under its Notes whether for principal, interest, fees,
expenses or otherwise, and (ii) the strict performance and observance by each
such Borrowing Subsidiary of all agreements, warranties and covenants in the
Notes and in the Agreement applicable to each such Borrowing Subsidiary (such
obligations collectively being the "Guaranteed Obligations").

         7.2. Guaranty Absolute. The Company guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms hereof,
regardless of any law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of the Banks with respect
thereto. The liability of the Company under this guaranty with regard to the
Guaranteed Obligations of each Borrowing Subsidiary shall be absolute and
unconditional irrespective of: 
   46

                                      -42-

                  (i) any lack of validity or enforceability or any illegality
         of such Borrowing Subsidiary's election to become a Borrower, its
         Notes, the Agreement and any amendment thereof (with regard to such
         Guaranteed Obligations), or any other obligation, agreement or
         instrument relating thereto;

                  (ii) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Guaranteed Obligations of such
         Borrowing Subsidiary or any other amendment or waiver of or any consent
         to departure from the Agreement (with regard to such Guaranteed
         Obligations);

                  (iii) any exchange, release or non-perfection of any
         collateral, or any release or amendment or waiver of or consent to
         departure from any other guaranty, for all or any of the Guaranteed
         Obligations of such Borrowing Subsidiary;

                  (iv)   any change in ownership of such Borrowing Subsidiary;

                  (v)    any acceptance of any partial payment(s) from such

         Borrowing Subsidiary; or

                  (vi) any other circumstance other than payment which might
         otherwise constitute a defense available to, or a discharge of, such
         Borrowing Subsidiary in respect of its Guaranteed Obligations provided
         that the Company may assert defenses arising from any Bank's breach of
         the Agreement to the same extent that a Borrowing Subsidiary would be
         able to do so.

         This guaranty shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any Guaranteed Obligation is
rescinded or must otherwise be returned by the Banks upon the insolvency,
bankruptcy or reorganization of any Borrowing Subsidiary or otherwise, all as
though such payment had not been made.

         7.3. Effectiveness, Enforcement. The guaranty herein of the Company
shall be effective and shall be deemed to be made with respect to each Advance
made to a Borrowing Subsidiary as of the time it is made. No invalidity,
irregularity or unenforceability by reason of any bankruptcy or similar law, or
any law or order of any government or agency thereof purporting to reduce, amend
or otherwise affect any liability of a Borrowing Subsidiary, and no defect in or
insufficiency or want of powers of any Borrowing Subsidiary or irregular or
improperly recorded exercise thereof, shall impair, affect, be a defense to or
claim against such guaranty. This guaranty is a continuing guaranty and shall
(i) survive any termination of the Agreement and (ii) remain in full force and
effect until payment in full and performance of all Guaranteed Obligations and

   47

                                      -43-

all other amounts payable under this guaranty. This guaranty is made for the
benefit of the Banks and their respective successors and assigns, and may be
enforced from time to time as often as occasion therefor may arise and without
requirement on the part of any Bank first to exercise any rights against any
Borrowing Subsidiary or to exhaust any remedies available to it against any
Borrowing Subsidiary or to resort to any other source or means of obtaining
payment of any of the Guaranteed Obligations or to elect any other remedy. Upon
any default by any Borrowing Subsidiary in the full and punctual performance of
any of the Guaranteed Obligations, the liabilities and obligations of the
Company hereunder shall, at the option of the Agent, become forthwith due and
payable.

         7.4. Waiver. The Company hereby waives promptness, diligence, protest,
notice of protest, all suretyship defenses, notice of acceptance and any other
notice with respect to any of the Guaranteed Obligations and this guaranty and
any requirement that the Banks protect, secure, perfect to ensure any security
interest or lien or any property subject thereto or exhaust any right or take
any action against any Borrowing Subsidiary or any other Person or any
collateral. The Company also irrevocably waives, to the fullest extent permitted
by law, all defenses which at any time may be available to it in respect of the
Guaranteed Obligations by virtue of any statute of limitations, valuation, stay,
moratorium law or other similar law now or hereafter in effect.

         7.5.  Subrogation; Subordination.

                  (a) Until the final payment and performance in full of all of
         the Obligations, the Company shall not exercise and hereby waives any
         rights against a Borrowing Subsidiary arising as a result of payment by
         the Company hereunder by way of subrogation, reimbursement,
         restitution, contribution or otherwise, and will not prove any claim in
         competition with the Agent or any Bank or any other creditor of a
         Borrowing Subsidiary whether now or hereafter existing or arising in
         respect of any payment hereunder in any bankruptcy, insolvency or
         reorganization case or proceeding of any nature; the Company will not
         claim any setoff, recoupment or counterclaim against a Borrowing
         Subsidiary in respect of any liability of the Borrowing Subsidiary to
         the Company; and the Company waives any benefit of and any right to
         participate in any collateral security which may be held by the Agent
         or any Bank.

                  (b) The payment of any amounts due with respect to any
         indebtedness of a Borrowing Subsidiary for money borrowed or credit
         received now or hereafter owed to the Company is hereby subordinated to
         the prior payment in full of all of the Guaranteed Obligations. The
         Company agrees that, after the occurrence of any default in the payment
         or performance of any of the Guaranteed Obligations, the Company will

   48

                                      -44-

         not demand, sue or otherwise attempt to collect any such indebtedness
         of a Borrowing Subsidiary to the Company until all of the Guaranteed
         Obligations shall have been paid in full. If, notwithstanding the
         foregoing sentence, the Company shall collect, enforce or receive any
         amounts in respect of such indebtedness while any Guaranteed
         Obligations are still outstanding, such amounts shall be collected,
         enforced and received by the Company as trustee for the Banks and the
         Agent and be paid over to the Agent, for the benefit of the Banks and
         the Agent on account of the Guaranteed Obligations without affecting in
         any manner the liability of the Company under the other provisions of
         this Agreement.

                  (c) The provisions of this Section 7.5 shall be supplemental
         to and not in derogation of any rights and remedies of the Banks and
         the Agent under any separate subordination agreement which the Agent
         may at any time and from time to time enter into with the Company for
         the benefit of the Banks and the Agent.

                   SECTION 8. EVENTS OF DEFAULT; ACCELERATION.

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

                  (a) if the Company or any Borrowing Subsidiary shall default
         in any payment of any principal amount outstanding hereunder or under
         the Notes when the same shall become due and payable, whether at
         maturity or at any date fixed for payment or prepayment or by
         declaration or otherwise other than due to a failure of a Bank or the
         Agent to charge an account of the Company or such Borrowing Subsidiary
         having a sufficient credit balance; or

                  (b) if the Company or any Borrowing Subsidiary shall fail to
         pay any interest with respect to principal outstanding hereunder or
         under the Notes or any commitment fee within two (2) Business Days
         after written notice by the Agent thereof shall have been given to the
         Company whether at maturity or at any date fixed for payment or
         prepayment or by declaration or otherwise; or

                  (c) if the Company or any Borrowing Subsidiary shall default
         in any material respect in the performance of or compliance with any
         term contained herein and such default shall not have been remedied
         within 15 days after written notice thereof shall have been given to

   49

                                      -45-

         the Company or such Borrowing Subsidiary by the Agent; or

                  (d) if any representation or warranty made in writing by or on
         behalf of the Company or any Borrowing Subsidiary herein or in
         connection with any of the transactions contemplated hereby shall prove
         to have been false or incorrect in any material respect on the date as
         of which made or deemed made; or

                  (e) if the Company or any Subsidiary shall fail to pay at
         maturity, or within any applicable period of grace, any obligation for
         money borrowed or credit advanced in an amount in excess of $250,000 in
         any one case or in aggregate for all obligations in default at such
         time, or shall have received notice of the existence of a default
         resulting from its failure to observe or perform any term, covenant or
         agreement contained in any agreement by which it is bound, evidencing
         or securing such money borrowed or credit advanced, and such default
         shall continue without waiver thereof beyond any period of grace
         provided with respect thereto; or

                  (f) if any Borrower, or any Subsidiary owning assets having a
         fair market value of $250,000 or more, shall make a general assignment
         for the benefit of creditors or shall petition or apply for the
         appointment of a liquidator or receiver of any Borrower or any such
         Subsidiary or of any substantial part of the assets of any Borrower or
         any such Subsidiary or shall commence any proceeding relating to any
         Borrower under any bankruptcy, reorganization, insolvency, readjustment
         of debt, dissolution or liquidation law or similar law of any
         jurisdiction, now or hereafter in effect; or

                  (g) if any such petition or application shall be filed or any
         such proceeding shall be commenced against any Borrower, or any
         Subsidiary owning assets having a fair market value of $250,000 or
         more, and such Borrower or such Subsidiary shall indicate its approval
         thereof, consent thereto or acquiescence therein or an order shall be
         entered appointing any liquidator or receiver, or adjudicating any
         Borrower or any such Subsidiary a bankrupt or insolvent, or approving a
         petition in any such proceeding, and such order shall remain in effect
         for more than thirty days, whether or not consecutive; or

                  (h) if any order shall be entered in any proceeding by or
         against any Borrower or any Subsidiary decreeing or permitting the
         dissolution or split-up of any Borrower or such Subsidiary or the
         winding up of its affairs and such order shall remain in effect for
         more than thirty days, whether or not consecutive; or

   50

                                      -46-

                  (i) if there shall remain in force, undischarged, unsatisfied
         and unstayed, for more than thirty days after the date on which payment
         is due thereon, whether or not consecutive, any final judgment against
         any Borrower or any Subsidiary which, with other outstanding final
         judgments, undischarged, against the Company and its Subsidiaries
         exceeds in the aggregate $250,000 after taking into account any
         insurance coverage;

then and in any such event the Agent may at any time, and upon written request
of the Majority Banks, shall, by written notice to the Borrower, and if the
Borrower is a Borrowing Subsidiary, the Company, declare: (i) the obligation of
each Bank to make Advances or Term Loans to the Borrowers to be terminated,
whereupon the same shall terminate, and/or (ii) the right of any Subsidiary to
become a Borrowing Subsidiary and the obligation of each Bank to make Advances
or Term Loans to such Subsidiary to be terminated, whereupon the same shall
forthwith terminate, and/or (iii) the principal amount of the Loan Accounts, in
the case of the Company and the Notes, in the case of all other Borrowers, all
interest thereon and all other amounts payable under this Agreement and the
Notes to be forthwith due and payable, whereupon the same shall become and be
forthwith due and payable without presentment, demand, protest or notice, all of
which are hereby expressly waived by each of the Borrowers. If any of the events
described in clauses (f), (g) or (h) above shall occur, and if such event
involves the Company (rather than a Subsidiary), the actions described in
clauses (i), (ii) and (iii) above shall occur automatically without requests by
the Banks, notice to the Company, or declaration by the Agent.

                               SECTION 9. SET-OFF.

         Any deposits or other sums at any time credited by or due from any Bank
to the Company or any Subsidiary and any securities or other property of the
Company or any Subsidiary in any Bank's possession may at all times be held and
treated as collateral security for the payment of the principal and interest and
any other amounts due hereunder or under the Notes, and any and all other
liabilities, direct or indirect, absolute or contingent, due or to become due,
now existing or hereafter arising, of any Borrower to the Banks. Regardless of
the adequacy of any collateral, any deposits (other than accounts used solely
for payroll or employee benefit plans) or other sums credited by or due from any
of the Banks to the Company or any Subsidiary may be appropriately applied to or
set-off against any principal, interest and any other amounts due hereunder or
under the Notes, and such other liabilities by the Banks at any time without
notice to any Borrower or compliance with any other condition precedent now or
hereafter imposed by statute, rule of law or otherwise (all of which are hereby
expressly waived by each Borrower). Each Bank agrees with the other Banks that
(i) if an amount to be set off is to be applied to indebtedness of a Borrower

   51

                                      -47-

hereunder to a Bank, other than the indebtedness evidenced by this Agreement or
the Notes, such amount shall be applied ratably to such other indebtedness and
to the indebtedness evidenced by this Agreement, and (ii) if a Bank shall
receive from any Borrower or from the Company with respect to such Borrower,
whether by voluntary payment, exercise of the right of setoff, counterclaim,
cross action, enforcement of the claim evidenced by this Agreement and/or the
Notes by proceedings against such Borrower or enforcement of any claim against
the Company in respect of its guaranty, in either case whether 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 indebtedness to it hereunder and/or under the Notes of such
Borrower, any amount in excess of such Bank's ratable portion of the payments
received by the Banks, such Bank will promptly 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 indebtedness to it hereunder
and/or under the Notes of such Borrower such Bank's proportionate payment;
provided, however, 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.

                             SECTION 10. THE AGENT.

         (a) The Agent is authorized to take such action on behalf of each of
the Banks and to exercise all such powers as are hereunder and in related
documents delegated to the Agent, together with such powers as are reasonably
incidental thereto.

         (b) The Agent may exercise its powers and execute its duties by or
through employees or agents and shall be entitled to take, and to rely on,
advice of counsel concerning all matters pertaining to its rights and duties
under this Agreement and the Notes. The Agent may utilize the services of such
persons as the Agent in its sole discretion may reasonably determine, and all
reasonable fees and expenses of any such persons (other than salaries of
employees of the Agent) shall be paid by the Company.

         (c) Neither the Agent nor any of its shareholders, directors, officers
or employees nor any other person assisting them in their duties nor any agent
or employee thereof, shall be liable to the Banks for any waiver, consent or
approval given or any action taken, or omitted to be taken, in good faith by it
or them hereunder or under the Notes, or in connection herewith or therewith or
be responsible to the Banks for the consequences of any oversight or error of
judgment whatsoever, except that the Agent or such other person, as the case may
be, may be liable for losses due to its willful misconduct or gross negligence.

   52

                                      -48-

         (d) The Agent shall not be responsible for the execution or validity or
enforceability of this Agreement, the Notes, or any instrument at any time
constituting, or intended to constitute, collateral security for this Agreement
or the Notes, or for the value of any such collateral security or for the
validity, enforceability or collectibility of any such amounts owing with
respect to this Agreement or the Notes, or for any recitals or statements,
warranties or representations herein or made in any certificate or instrument
hereafter furnished to it by or on behalf of any of the Borrowers or be bound to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, covenants or agreements herein or in any instrument at any time
constituting, or intended to constitute, collateral security for this Agreement
or the Notes. The Agent shall not be bound to ascertain whether any notice,
consent, waiver or request delivered to it by any of the Borrowers or any holder
of any of the Notes shall have been duly authorized or is true, accurate and
complete. The Agent has not made nor does it now make any representations or
warranties, express or implied, nor does it assume any liability to the Banks
with respect to the creditworthiness or financial conditions of the Company or
any of its Subsidiaries, and each Bank represents and warrants to the Agent that
it has made its own independent evaluation of the creditworthiness of the
Company and its Subsidiaries and has not relied upon the Agent or any material
or information furnished by the Agent in making such evaluation.

         (e) If in the opinion of the Agent the distribution of any amount
received by it in such capacity hereunder or under the Notes might involve it in
liability, it may refrain from making such distribution until its right to make
such 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.
With respect to obligations of any of the Borrowers hereunder, a payment to the
Agent shall be deemed to be a payment to the Banks.

         (f) The Agent may deem and treat the payee of any Note as the absolute
owner thereof for all purposes hereof until it shall have been furnished in
writing with a different name by such payee or by a subsequent holder.

         (g) In its individual capacity, The First National Bank of Boston shall
have the same obligations and the same rights, powers and privileges in respect
to its Commitment and the Loans made by it hereunder, and as the holder of any
of the Notes, as it would have were it not also the Agent.

         (h) The Company agrees to reimburse the Agent from time to time on
demand for its reasonable out-of-pocket expenses (including reasonable fees and

   53

                                      -49-

expenses of counsel)  incurred in  connection  with the  administration  of this
Agreement.

         (i) The Agent may resign at any time upon ten (10) days' prior written
notice to the Banks and the Company. In such event, a successor Agent shall be
designated by the Banks, provided that the Company shall have the right to
approve such successor.

                           SECTION 11. MISCELLANEOUS.

         11.1. Expenses. Whether or not the transactions contemplated hereby
shall be consummated, the Company will on demand (a) pay any taxes or filing
fees in connection with the transactions contemplated by this Agreement and save
the Banks harmless from and against any and all liabilities resulting from any
delay in paying or omission to pay any such fee or tax, (b) pay the reasonable
fees, expenses and disbursements of Counsel to the Agent incurred in connection
with the negotiation, preparation and completion of this Agreement and the
transactions and other documents contemplated by this Agreement, or any
subsequent waivers, consents or amendments in connection therewith, (c) pay the
reasonable costs and expenses of the Agent's examinations conducted in
accordance with Section 5.5 hereof, and (d) pay all reasonable out-of-pocket
expenses (including, without limitation, reasonable attorney's fees and costs,
costs of consultants, accountants, investment bankers and other experts)
incurred by the Banks in connection with the enforcement of this Agreement. The
Company's obligation to pay any amount pursuant to this Section 11.1 shall
survive payment or satisfaction of all other amounts owing under this Agreement.

         11.2. Notices, etc. All notices, requests and other communications
pursuant to this Agreement shall be in writing and shall be mailed by
first-class mail, postage prepaid, or sent by telegraph confirmed by letter,

authorized officers and shall not be revocable by such Borrower and shall
obligate such Borrower to borrow a requested Advance or Term Loan for, or to
convert an Advance to, a currency, Borrowing Day, Interest Period or interest
rate as may be so specified. Any election made by a Borrower pursuant to
Sections 2.3 or 2.10(b) shall be binding upon such Borrower and irrevocable.
Notice of any prepayment having been given as required and all of the other
conditions to such prepayment having been satisfied by such Borrower in
compliance with the provisions of Sections 2.3 or 2.10(b), that amount of the
principal of any Advance or Term Loan which shall have been designated for
prepayment in such notice shall, on the date specified in such notice, become
absolutely due and payable by such Borrower.

         11.3. Reliance, etc. All covenants, agreements, representations and
warranties made herein, in certificates delivered pursuant hereto or otherwise
in writing in connection with the transactions evidenced hereby shall be deemed
to have been material and relied upon by the Banks, notwithstanding any
investigation made by the Banks or on the Banks' behalf and shall survive the
execution of this Agreement and the making of each Advance or Term Loan
hereunder and shall continue in full force and effect until all of the
obligations of the Company and each Borrowing Subsidiary hereunder have been
paid and satisfied in full and all commitments of the Banks to extend credit
hereunder have terminated.

         11.4.  Captions.  The captions in this  Agreement  are for  convenience

         11.5. Consents, Amendments, Waivers, etc. Except as otherwise expressly
set forth in any particular provision of this Agreement, any consent or approval
required or permitted by this Agreement to be given by the Banks may be given,
and any term of this Agreement or of any other instrument related hereto or
mentioned herein may be amended, and the performance or observance by any
Borrowers of any term of this Agreement may be waived (either generally or in a
particular instance and either retroactively or prospectively) with, but only
with, the written consent of the Borrowers and the Majority Banks, provided,
however, that:

                  (a) Without the written consent of such Banks as hold 100% of
         the aggregate outstanding principal amount of the Loan Accounts and all
         Notes, or if no principal is outstanding, of the Total Commitment,

                           (i) no reduction in the principal amount of, interest
                  rate on, Commitment Fees relating to the Advances or Term
                  Loans or the Facility Fee shall be made; and

                           (ii) no extension or postponement of the stated time
                  of payment of the principal amount of, interest on, Commitment
                  Fees relating to, the Advances or Term Loans or the Facility
                  Fee shall be made; and

                           (iii)  no  increase  in the  amount,  or  extension
                  of the term,  of the Total  Commitment beyond those provided
                  for hereunder shall be made;

                           (iv) no modification of, or amendment to, or waiver
                  of compliance with, the provisions of Sections 8(a), (b), (f),
                  (g) or (h) or 11.5 hereof shall be made.

No modification or waiver of any provision of this Agreement, and no consent to
departure by any Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the required percentage of the Banks, and
then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. No notice or demand on any Borrower in any case
shall entitle any such Borrower or any other Borrower to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
Banks' right to take any other or further action in any circumstances without
notice or demand. No failure or delay on the Agent's or the Banks' part in
exercising any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right. No right, power or remedy conferred

   56

                                      -52-

hereby upon Agent or the Banks shall be exclusive of any other right, power or
remedy referred to herein or now or hereafter available at law, in equity, by
statute or otherwise.

         11.6. Benefit, etc. The rights of the Borrowers under this Agreement
shall not be assignable by the Borrowers without the prior written consent of
the Banks. This Agreement shall be binding upon the successors and assigns of
the Borrowers and, except as otherwise provided in Section 11.12, shall inure to
the benefit of and be binding upon each Bank and its successors and assigns.

         11.7. Exchange Rate. If, for the purpose of obtaining judgment in any
court or obtaining an order enforcing a judgment, it becomes necessary to
convert any amount due under this Agreement (including, without limitation,
amounts due under Section 7.1 hereof) in Dollars or in any other currency
(hereinafter in this Section 11.7 called the "first currency") into any other
currency (hereinafter in this Section 11.7 called the "second currency"), then
the conversion shall be made at the Agent's spot rate of exchange for buying the
first currency with the second currency prevailing at the Agent's close of
business on the Business Day next preceding the day on which the judgment is
given or (as the case may be) the order is made. In the event that there is a
difference between the rate of exchange on the basis of which the amount of such
judgment or order is determined and the rate of exchange prevailing on the date
of payment, each Borrower hereby agrees to pay such additional amount as may be
necessary to ensure that the amount paid on such date in the second currency is
the amount in such second currency which, when converted at the Agent's spot
rate of exchange for buying the first currency with the second currency
prevailing at the Agent's opening of business on the date of payment, is the
amount which was due under this Agreement in the first currency before such
judgment was obtained or made. Any amount due from any Borrower to the Banks
under the second sentence of this Section 11.7 will be due as a separate debt of
such Borrower to the Banks and shall not be affected by judgment or order being
obtained for any other sum due under or in respect of this Agreement. The
covenant contained in this Section 11.7 shall survive the payment in full of all
of the other obligations of the Borrowers under this Agreement.

         11.8.  Governing Law. This Agreement  shall be governed by the laws of
the  Commonwealth of  Massachusetts  and is intended to take effect as a sealed

instrument.

         11.9.  Counterparts.  This Agreement may be executed in one or more
counterparts  each  of   which   shall  constitute  an original  but which taken
together shall constitute but one agreement.  In proving this Agreement it shall
not be necessary to produce or account for more than one such counterpart.

         11.10.  Consent To Jurisdiction, Waiver of Jury Trial.

                  (a) Each Borrowing Subsidiary hereby irrevocably submits to
         the jurisdiction of any Massachusetts state or federal court sitting in
         Boston over any action or proceeding arising out of or relating to this
         Agreement and each Borrowing Subsidiary hereby irrevocably agrees that
         all claims in respect of such action or proceeding may be heard and
         determined in such Massachusetts state or federal court. Each Borrowing
         Subsidiary hereby appoints the Company as its process agent (the
         "Process Agent"), and the Company hereby agrees to act as its agent at
         its office specified in Section 11.2(a) to receive on its behalf and
         its property service of copies of the summons and complaint and any
         other process which may be served in any such action or proceeding.
         Such service may be made to any Borrowing Subsidiary by mailing or
         delivering a copy of such process to such Borrowing Subsidiary in care
         of the Process Agent at the Process Agent's address set forth above,
         and each Borrowing Subsidiary hereby irrevocably authorizes and directs
         the Process Agent to accept such service on its behalf. As an
         alternative method of service, each Borrowing Subsidiary also
         irrevocably consents to the service of any and all process in any such
         action or proceeding by the hand delivery or mailing of copies of such
         process to such Borrowing Subsidiary at its address specified in its
         election to become a Borrowing Subsidiary. Each Borrowing Subsidiary
         agrees that a final judgment in any such action or proceeding shall be
         conclusive and may be enforced in other jurisdictions by suit on the
         judgment or in any other manner provided by law.

                  (b) Each Borrowing Subsidiary may change its Process Agent
         hereunder by substituting and appointing as its Process Agent another
         Person approved by the Agent, such substitution and appointment to be
         made pursuant to a written instrument executed by such Borrowing
         Subsidiary and such Person in form and substance approved by the Agent,
         which approval will not be unreasonably withheld; provided, however,
         that each Borrowing Subsidiary shall have a Process Agent at all times.

                  (c) Nothing in this Section 11.10 shall affect the right of
         the Banks to serve legal process in any other manner permitted by law
         or affect the right of the Banks to bring any action of proceeding
         against any Borrowing Subsidiary of its property in the courts of any
         other jurisdiction.

                  (d) Each Borrower 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 or the Notes or any rights or obligations hereunder

   58

                                      -54-

         or thereunder or the performance of such rights and obligations. Except
         as prohibited by law, each Borrower hereby waives any right which 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.

         11.11. Transitional Provisions. All "Loans", as defined in this
Agreement, which were outstanding hereunder as of the date hereof, shall for
purposes of this Agreement be deemed Advances made under and subject to the
terms and conditions of this Agreement, even if such Advances are not in
accordance with the Commitment Percentages of the Banks hereunder and shall bear
interest at the rate determined under this Agreement. Upon the termination of
the Interest Period determined in accordance with this Agreement with respect to
such Advances, the Company shall repay such Advances and may, subject to the
terms and conditions of this Agreement, reborrow such amounts in accordance with
the Banks' Commitment Percentages. The Commitment Fee payable to each Bank shall
be determined on the basis of each Bank's portion of the unused Total Commitment
rather than its Commitment Percentage until the Advances are made in accordance
with the Commitment Percentages. This Agreement shall not become effective until
the Company shall have paid the Agent's fees and expenses in accordance with
Section 11.1(b) hereof in connection with the completion of this Agreement.

         11.12. Exempt Character of Transaction. This Agreement is made with the
Banks in reliance upon their several representations to the Company, which by
their execution of this Agreement they hereby confirm, that each Bank for itself
and not for any other Bank has no present intention of selling or otherwise
disposing of any interest in the Loan Accounts or the Notes other than
participations by banking institutions. The Company represents to the Banks that
it has not, either directly or through any agent, offered any interest in the
Notes (or similar instruments) for sale to or solicited any offers to buy any
interest therein from, or otherwise approached or negotiated in respect of any
interest therein with, any person or persons other than the Banks. If any Bank
is not incorporated under the laws of the United States of America or any state
thereof, it shall, prior to the date on which any interest or fees are payable
hereunder for its account, deliver to the Borrower and the Agent certification
as to its exemption from deduction or withholding of any United States federal
income taxes.

                        12. ASSIGNMENT AND PARTICIPATION.

         12.1. Conditions to Assignment by Banks. Except as provided herein,
each Bank may assign to one or more Eligible Assignees all of its interest,
rights and obligations under this Agreement (including all of its Commitment
Percentage and Commitment and the all of the Loans at the time owing to it and
the Notes held by it); provided that (a) each of the Agent and, unless a Default

   59

                                      -55-

or Event of Default shall have occurred and be continuing, the Company shall
have given its prior written consent to such assignment, which consent, in the
case of the Company, will not be unreasonably withheld, (b) each such assignment
shall be constant, and not a varying, percentage of all the assigning Bank's
rights and obligations under this Agreement (c) each assignment shall be in an
amount that is equal to 100% of such assigning Bank's Commitment and (d) the
parties to such assignment shall execute and deliver to the Agent, for recording
in the Register (as hereinafter defined), an Assignment and Acceptance,
substantially in the form of Exhibit A hereto (an "Assignment and Acceptance"),
together with any Note subject to such assignment. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, which effective date shall be at least five
(5) Business Days after the execution thereof, (i) the assignee thereunder shall
be a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Bank hereunder, and (ii) the assigning Bank
shall, to the extent provided in such assignment and upon payment to the Agent
of the registration fee referred to in Section 12.3, be released from its
obligations under this Agreement.

         12.2 Certain Representations and Warranties; Limitations; Covenants. By
executing and delivering an Assignment and Acceptance, the parties to the
assignment thereunder confirm to and agree with each other and the other parties
hereto as follows:

                  (a) other than the representation and warranty that it is the
         legal and beneficial owner of the interest being assigned thereby free
         and clear of any adverse claim, the assigning Bank makes no
         representation or warranty, express or implied, and assumes no
         responsibility with respect to any statements, warranties or
         representations made in or in connection with this Agreement or the
         execution, legality, validity, enforceability, genuineness, sufficiency
         or value of this Agreement, the other Loan Documents or any other
         instrument or document furnished pursuant hereto or the attachment,
         perfection or priority of any security interest or mortgage,

                  (b) the assigning Bank makes no representation or warranty and
         assumes no responsibility with respect to the financial condition of
         the Company and its Subsidiaries or any other Person primarily or
         secondarily liable in respect of any of the Obligations, or the
         performance or observance by the Company and its Subsidiaries or any
         other Person primarily or secondarily liable in respect of any of the
         Obligations of any of their obligations under this Agreement or any of
         the other Loan Documents or any other instrument or document furnished
         pursuant hereto or thereto;

   60

                                      -56-

                  (c) such assignee confirms that it has received a copy of this
         Agreement, together with copies of the most recent financial statements
         referred to in Section 4.1.7 and Section 5.4 and such other documents
         and information as it has deemed appropriate to make its own credit
         analysis and decision to enter into such Assignment and Acceptance;

                  (d) such assignee will, independently and without reliance
         upon the assigning Bank, 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 credit decisions in taking or not taking
         action under this Agreement;

                  (e)  such assignee represents and warrants that it is an
         Eligible Assignee;

                  (f) such assignee appoints and authorizes the Agent to take
         such action as agent on its behalf and to exercise such powers under
         this Agreement and the other Loan Documents as are delegated to the
         Agent by the terms hereof or thereof, together with such powers as are
         reasonably incidental thereto;

                  (g) such assignee agrees that it will perform in accordance
         with their terms all of the obligations that by the terms of this
         Agreement are required to be performed by it as a Bank; and

                  (h) such assignee represents and warrants that it is legally
         authorized to enter into such Assignment and Acceptance.

         12.3. Register. The Agent shall maintain a copy of each Assignment and
Acceptance delivered to it and a register or similar list (the "Register") for
the recordation of the names and addresses of the Banks and the Commitment
Percentage of, and principal amount of the Loans owing to the Banks from time to
time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Company, the Agent and the Banks may treat each Person
whose name is recorded in the Register as a Bank hereunder for all purposes of
this Agreement. The Register shall be available for inspection by the Company
and the Banks at any reasonable time and from time to time upon reasonable prior
notice. Upon each recordation, the assigning Bank agrees to pay to the Agent a
registration fee in the sum of $3,000.

         12.4. New Notes. Upon its receipt of an Assignment and Acceptance
executed by the parties to such assignment, together with each Note subject to
such assignment, the Agent shall (a) record the information contained therein in
the Register, and (b) give prompt notice thereof to the Company and the Banks
(other than the assigning Bank). Within five (5) Business Days after receipt of
such notice, each Borrowing Subsidiary, at its own expense, shall execute and

   61

                                      -57-

deliver to the Agent, in exchange for each surrendered Note, a new Note to the
order of such Eligible Assignee in an amount equal to the amount assumed by such
Eligible Assignee pursuant to such Assignment and Acceptance. Such new Notes
shall provide that they are replacements for the surrendered Notes, shall be in
an aggregate principal amount equal to the aggregate principal amount of the
surrendered Notes, shall be dated the effective date of such in Assignment and
Acceptance and shall otherwise be substantially the form of the assigned Notes.
The surrendered Notes shall be cancelled and returned to the Company.

         12.5. Participations. Each Bank may sell participations to one or more
banks or other entities in all or a portion of such Bank's rights and
obligations under this Agreement and the other Loan Documents; provided that (a)
each such participation shall be in an amount of not less than $5,000,000, or,
if such Bank's Commitment is less than $5,000,000, the amount of such Bank's
Commitment, (b) any such sale or participation shall not affect the rights and
duties of the selling Bank hereunder to the Company and (c) the only rights
granted to the participant pursuant to such participation arrangements with
respect to waivers, amendments or modifications of the Loan Documents shall be
the rights to approve waivers, amendments or modifications that would reduce the
principal of or the interest rate on any Loans, extend the term or increase the
amount of the Commitment of such Bank as it relates to such participant, reduce
the amount of any commitment fees to which such participant is entitled or
extend any regularly scheduled payment date for principal or interest.

         12.6. Disclosure. The Company agrees 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 and potential assignees hereunder; provided that such assignees or
potential assignees shall agree (a) to treat in confidence such information
unless such information otherwise becomes public knowledge, (b) not to disclose
such information to a third party, except as required by law or legal process
and (c) not to make use of such information for purposes of transactions
unrelated to such contemplated assignment. In addition, the parties hereto
hereby agree that any Bank may disclose information obtained by such Bank
pursuant to this Agreement to participants and potential participants hereunder,
provided that such information is public information. Such Bank shall not
disclose any non-public information to any participant or potential participant
hereunder without the Company's prior written consent. In addition, such
participant or potential participant shall agree (a) to treat in confidence such
information unless such information otherwise becomes public knowledge, (b) not
to disclose such information to a third party, except as required by law or
legal process and (c) not to make use of such information for purposes of
transactions unrelated to such contemplated participation

         12.7.  Assignee or Participant Affiliated with the Company. If any
assignee  Bank  is  an  Affiliate of the Company,  then any such  assignee  Bank

   62

                                      -58-

shall have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Agent pursuant to Section 8, and the
determination of the Majority Banks shall for all purposes of this Agreement and
the other Loan Documents be made without regard to such assignee Bank's interest
in any of the Loans. If any Bank sells a participating interest in any of the
Loans to a participant, and such participant is the Company or an Affiliate of
the Company, then such transferor Bank shall promptly notify the Agent of the
sale of such participation. A transferor Bank shall have no right to vote as a
Bank hereunder or under any of the other Loan Documents for purposes of granting
consents or waivers or for purposes of agreeing to amendments or modifications
to any of the Loan Documents or for purposes of making requests to the Agent
pursuant to Section 8 to the extent that such participation is beneficially
owned by the Company or any Affiliate of the Company, and the determination of
the Majority Banks shall for all purposes of this Agreement and the other Loan
Documents be made without regard to the interest of such transferor Bank in the
Loans to the extent of such participation.

         12.8. Miscellaneous Assignment Provisions. Any assigning Bank shall
retain its rights to be indemnified pursuant to the Agreement with respect to
any claims or actions arising prior to the date of such assignment. If any
assignee Bank is not incorporated under the laws of the United States of America
or any state thereof, it shall, prior to the date on which any interest or fees
are payable hereunder or under any of the other Loan Documents for its account,
deliver to the Company and the Agent certification as to its exemption from
deduction or withholding of any United States federal income taxes. Anything
contained in this Section 12 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 Banks organized under ss.4 of the Federal Reserve Act, 12 U.S.C.
ss.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.

         12.9.  Assignment by Company. Neither the  Company  nor any Subsidiary
shall assign   or  transfer any of  its rights or  obligations  under any of the
Loan Documents without the prior written consent of each of the Banks.
