$                                                          Date:

         FOR VALUE RECEIVED, the undersigned (hereinafter, together with their
successors in title and assigns, collectively, called the "Borrowers"), by this
promissory note (hereinafter, together with the Schedule annexed hereto, called
"this Note"), absolutely and unconditionally and jointly and severally promise
to pay to the order of ____________________, a national banking association
organized under the laws of the United States of America (hereinafter, together
with its successors in title and assigns, called the "Bank"), the principal sum
of ________________ Dollars ($___________), or so much thereof as shall have
been advanced by the Bank to the Borrowers by way of revolving credit loans
under the Loan Agreement (as hereinafter defined) and shall remain outstanding,
such payment to be made as hereinafter provided, and to pay interest on the
principal sum outstanding hereunder from time to time from the date hereof until
the said principal sum or the unpaid portion thereof shall have become due and
payable as hereinafter provided.

         Capitalized terms used herein without definition shall have the meaning
set forth in the Loan Agreement.

         The unpaid principal (not at the time overdue) under this Note shall

Agreement. Accrued interest on the unpaid principal under this Note shall be
payable on the dates specified in the Loan Agreement.

         On __________, the date of the final maturity of this Note, there shall

(to the extent permitted by applicable law) bear interest at the rates and on
the terms provided by the Loan Agreement. The unpaid interest accrued on each
overdue amount in accordance with the foregoing terms of this paragraph shall
become and be absolutely and jointly and severally due and payable by the
Borrowers to the Bank on demand by the Administrative Agent. Interest on each

this paragraph, and will (to the extent permitted by applicable law) be


                                      -1-


compounded daily until the obligations of the Borrowers in respect of the
payment of such overdue amount shall be discharged (whether before or after
judgment).

         Each payment of principal, interest or other sum payable on or in
respect of this Note or the indebtedness evidenced hereby shall be made by the
Borrowers directly to the Administrative Agent in dollars, for the account of
the Bank, at the address of the Administrative Agent set forth in the Loan
Agreement, on the due date of such payment, and in immediately available and
freely transferable funds. All payments on or in respect of this Note or the
indebtedness evidenced hereby shall be made without set-off or counterclaim and
free and clear of and without any deductions, withholdings, restrictions or
conditions of any nature.

         This Note is made and delivered by the Borrowers to the Bank pursuant
to the Revolving Credit and Term Loan Agreement, dated as of June 29, 2000,
among (i) the Borrowers, (ii) the Banks and (iii) the Administrative Agent
(hereinafter, as originally executed, and as now or hereafter varied or
supplemented or amended and restated, called the "Loan Agreement"), to which
reference is hereby made for a statement of the terms and conditions (to the
extent not set forth herein) under which the Loans evidenced by this Note were
made and are to be repaid. This Note evidences the joint and several obligation
of the Borrowers (a) to repay the principal amount of the Bank's Commitment

pursuant to the Loan Agreement; (b) to pay interest, as herein and therein
provided, on the principal amount hereof remaining unpaid from time to time; and
(c) to pay other amounts which may become due and payable hereunder or
thereunder as herein and therein provided. The payment of the principal of and
the interest on this Note and the payment of all (if any) other amounts as may
become due and payable on or in respect of this Note are secured by certain
collateral, as evidenced by the Security Documents. Reference is hereby made to
the Loan Agreement (including the EXHIBITS and SCHEDULES annexed thereto) and to
the other Security Documents for a complete statement of the terms thereof and
for a description of such collateral.

         The Borrowers will have the right to prepay the unpaid principal of
this Note in full or in part upon the terms contained in the Loan Agreement. The
Borrowers will have an obligation to prepay principal of this Note from time to
time if and to the extent required under, and upon the terms contained in, the
Loan Agreement. Any partial payment of the indebtedness evidenced by this Note
shall be applied in accordance with the terms of the Loan Agreement.

         Pursuant to and upon the terms contained in Section 7 of the Loan
Agreement, the entire unpaid principal of this Note, all of the interest accrued
on the unpaid principal of this Note and all (if any) other amounts payable on
or in respect of this Note or the indebtedness evidenced hereby may be declared
to be immediately due and payable, whereupon the entire unpaid principal of this
Note, all of the interest accrued on the unpaid principal of this Note and all
(if any) other amounts payable on or in respect of this Note or the indebtedness
evidenced hereby shall (if not already due and payable)


                                      -2-


forthwith become and be due and payable to the Bank without presentment, demand,
protest or any other formalities of any kind, all of which are hereby expressly
and irrevocably waived by the Borrowers, excepting only for notice expressly
provided for in the Loan Agreement.

         All computations of interest payable as provided in this Note shall be
made by the Administrative Agent in accordance with the terms of the Loan
Agreement. The interest rate in effect from time to time shall be determined in
accordance with the terms of the Loan Agreement.

         Should all or any part of the indebtedness represented by this Note be
collected by action at law, or in bankruptcy, insolvency, receivership or other
court proceedings, or should this Note be placed in the hands of attorneys for
collection after default, the Borrowers hereby promise to pay to the holder of
this Note, upon demand by the holder hereof at any time, in addition to
principal, interest and all (if any) other amounts payable on or in respect of
this Note or the indebtedness evidenced hereby, all court costs and reasonable
attorneys' fees and all other collection charges and expenses reasonably
incurred or sustained by the holder of this Note.

         No delay or omission on the part of the Bank or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Bank or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any further occasion.

         Each of the Borrowers and every endorser and guarantor of this Note
hereby irrevocably waives notice of acceptance, presentment, demand, notice of
nonpayment, protest, notice of protest, suit and all other demands, notices and
other conditions precedent in connection with the delivery, acceptance,
performance, default, collection and/or enforcement of this Note or any
collateral or security therefor, except for notices expressly provided for in
the Loan Agreement or any other Loan Document, and assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of collateral and to the addition or release
of any other party or person primarily or secondarily liable.

         Each of the Borrowers hereby absolutely and irrevocably consents and
submits, for itself and its property, to the non-exclusive jurisdiction of the
courts of the Commonwealth of Massachusetts or of the United States of America
for the District of Massachusetts in connection with any actions or proceedings
brought against any Borrower by the holder hereof arising out of or relating to
this Note.

         THE BORROWERS AND THE BANK MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND
