deposits in U.S. dollars, for a period of time comparable to such
Eurodollar Interest Period, which appears on the Telerate page
3750 as of 11:00 a.m.  London time on the day that is two (2)
Eurodollar Banking Days preceding the first day of such Eurodollar

which are offered by four major banks in the London interbank
market at approximately 11:00 a.m. London time on the day that is
two (2) Eurodollar Banking Days preceding the first day of such

to such Eurodollar Interest Period offered by major banks in New
York City at approximately 11:00 a.m. New York City time, on the
day that is two Eurodollar Banking days preceding the first day of

              AMOUNTS AND TERMS OF THE REVOLVING LOANS,
                  LETTERS OF CREDIT AND TERM LOANS

      Section 2.01.  Revolving Loans and Letters of Credit.  (a) 
Subject to the terms and conditions set forth in this Agreement,
the Bank will make loans ("Revolving Loans") to the Borrower at
the Principal Office of the Bank in an aggregate principal amount
at any time outstanding not exceeding the lesser of (i) the
Borrowing Base or (ii) the Line of Credit Amount (less the
aggregate amount then available to be drawn under outstanding
<PAGE>
<PAGE>
Letters of Credit) on any Banking Day prior to the first to occur
of (i) the Expiration Date or (ii) the earlier termination
pursuant to Section 7.02(b) of the Line of Credit, in such amounts
as the Borrower may request in accordance with Section 2.03. 
Revolving Loans shall be evidenced by and payable in accordance
with the terms of the Line of Credit Note.  Principal of Revolving
Loans that is prepaid may be reborrowed.

      (b)  Subject to the terms and conditions set forth in this
Agreement, the Bank will issue Letters of Credit for the account
of the Borrower in such aggregate stated amounts not exceeding the
lesser of (i) the Borrowing Base or (ii) the Line of Credit Amount
(less outstanding Revolving Loans) as the Borrower shall request
on reasonable prior notice, in favor of a supplier or other
beneficiary to which the Borrower has actual or contingent
obligations incurred in the ordinary course of business.  The
Borrower agrees to complete appropriately, execute and deliver in
connection with each Letter of Credit the Bank"s then standard
form of standby letter of credit application and agreement (each
an "LC Agreement").  The expiration date and other material terms
and provisions of each SBLC shall be subject to the advance
approval of the Bank.  The Borrower agrees to pay the Bank"s fees
applicable to issuance, amendment and transfer of Letters of
Credit and drawings thereunder, and agrees to pay the Bank the
applicable Letter of Credit Fee, calculated on the basis of actual
days elapsed and a 360-day year and payable in accordance with the
Bank"s then standard practices, with respect to the aggregate
amount available to be drawn under outstanding Letters of Credit
from the date of issuance to and including the expiration dates
thereof.  Any sum not reimbursed by the Borrower in accordance
with the relevant LC Agreement shall be payable ON DEMAND, shall
constitute a "Loan" for purposes of this Agreement and shall bear
interest which shall accrue, be calculated and be payable (in the
absence of demand) as provided in the Line of Credit Note.  All
obligations of the Borrower in respect of Letters of Credit, LC
Agreements and related Loans shall be secured by and entitled to
the benefits of the Collateral and the Security Agreement.  In the
event that all Loans have been repaid and the Line of Credit or
Term Loan Facility shall no longer be in effect, the Bank may
require that the Borrower maintain cash collateral in an amount
and form satisfactory to the Bank in respect of the amount then
available to be drawn under any Letter of Credit outstanding
thereafter.

      (c)   In the event that outstanding Revolving Loans and the
aggregate amount then available to be drawn under outstanding
Letters of Credit exceed the lesser of (i) the Borrowing Base or
(ii) the Line of Credit Amount, the Borrower shall immediately
repay Revolving Loans in an amount sufficient to eliminate such
excess.

      Section 2.02.  Term Loans.  (a)  Subject to the terms and
conditions set forth in this Agreement, the Bank will make loans
("Term Loans") to the Borrower at the Principal Office of the Bank
in an aggregate principal amount at any time outstanding not
exceeding the Term Loan Facility Amount (less the aggregate
principal amount of all Term Loans then outstanding), on any
Banking Day prior to the first to occur of (i) the Expiration Date
or (ii) the earlier termination pursuant to Section 7.02(b) of the
Term Loan Facility, in such amounts as the Borrower may request in
accordance with Section 2.03.  Each Term Loan shall be evidenced
by and payable in accordance with the terms of the Term Note
evidencing such Term Loan.  Principal of Term Loans that is repaid
or prepaid may be reborrowed.
<PAGE>
<PAGE>
      (b)  Term Loans shall be made to (i) finance or refinance
purchases by the Borrower of Equipment ("Equipment Loans") or (ii)
finance establishment of new business locations, Acquisitions or
permanent working capital ("Acquisition/WC Loans"); provided that
(x) no Equipment Loan shall be made in a principal amount
exceeding seventy-five percent (75%) of the purchase price of the
relevant Equipment, as evidenced by copies of purchase orders,
invoices or other documents submitted to the Bank in connection
with the request for the Equipment Loan, and (y) without the prior
written consent of the Bank, the aggregate Acquisition/WC Loans
outstanding at any time shall not exceed the Acquisition/WC Loan
Sublimit.

      Section 2.03.  Requests for Revolving and Term Loans.  The
Borrower will give the Bank written notice of each requested
Revolving Loan or Term Loan, specifying the type, amount and date
of each such Loan requested, and, in the case of each Term Loan,
the Term Loan Maturity Date therefor.  Any Loan request received
after 11:00 a.m. Boston time on the Banking Day on which the Loan
is requested to be made shall be deemed received on the next
succeeding Banking Day.  Requests for Eurodollar Rate Advances and
Cost of Funds Rate Advences are subject to the additional
requirements as to timing set forth in Sections 2.05 and 2.06,
respectively.  Requests for Equipment Loans shall be accompanied
by the documents referred to in Section 2.02(b).

      Section 2.04.  Revolving and Term Loan Interest Payments. 
The Borrower will pay interest on the principal amount of the
Revolving Loans and the Term Loans outstanding from time to time,
from the date of each Loan until payment thereof in full and the
termination of this Agreement, such interest to be payable in
arrears as provided in this Section, Sections 2.05, 2.06 and 3.06,
and on the date of payment in full of the Revolving Loans and each
Term Loan.  Except (i) in the case of Revolving Loans, when
constituting Eurodollar Rate Advances pursuant to the Borrower"s
timely election under Section 2.05, or (ii) in the case of Term
Loans, when constituting Eurodollar Rate Advances pursuant to the
Borrower"s timely election under Section 2.05 or Cost of Funds
Rate Advances pursuant to the Borrower"s timely election under
Section 2.06, all Revolving Loans and Term Loans shall bear
interest at a fluctuating rate per annum equal to the Prime Rate
plus the applicable Margin, with a change in each such rate of
interest to become effective on the same day on which any change
in the Prime Rate is effective.  Interest based on the Prime Rate
shall be calculated on the basis of actual days elapsed and a 360-
day year and shall be payable monthly on the first day of each
calendar month.  At the Bank"s option, to the extent permitted by
applicable law, overdue principal of the Revolving Loans and the
Term Loans and overdue interest thereon shall bear interest at a
rate which at all times shall be four percent (4%) plus the
interest rate otherwise then in effect hereunder, compounded
monthly at the Bank"s option and payable on demand.

      Section 2.05.  Eurodollar Rate Option.  Subject to the terms
and conditions set forth in this Agreement, (i) any Revolving Loan
or Term Loan and (ii) any portion of the outstanding Revolving
Loans, in any case in an amount equal to $100,000 or a greater
integral multiple of $100,000, may be made or maintained subject
to a Eurodollar Rate election as below provided:
            
            (a)  A Eurodollar Rate election shall be made in
writing (or, if by telephone, confirmed in writing on the same
day) by 11:00 a.m. Boston time two (2) Eurodollar Banking Days
before the commencement of the relevant Eurodollar Interest
<PAGE>
<PAGE>
Period, specifying the amount of the Eurodollar Rate Advance and
the Interest Period therefor; provided that in the case of a
Revolving Loan or a portion of the outstanding Revolving Loans no
such election shall be effective if it would cause there to be
outstanding more than five (5) Eurodollar Rate Advances with
respect to Revolving Loans.  In the absence of a timely Eurodollar
Rate election with respect thereto, or, in the case of the Term
Loans, a timely Cost of Funds Rate election, all Revolving Loans
and Term Loans shall bear interest as provided in Section 2.04.
            
            (b)  Interest on each Eurodollar Rate Advance shall be
due and payable in arrears monthly on or about the same day of
each calendar month numerically corresponding to the first day of
the current Eurodollar Interest Period with respect thereto (e.g.
for a Eurodollar Interest Period beginning November 15, interest
payments will fall on or about the 15th day of each succeeding
month), on the last day of such Eurodollar Interest Period and on
the date of payment of the relevant Note in full, at the
applicable Eurodollar Rate (computed on the basis of a 360-day
year for the actual number of days elapsed, including the first
day of each Interest Period but excluding the last day).
            
            (c)  In the event that the Bank is unable to determine
the Eurodollar Rate for any Eurodollar Interest Period due to
circumstances affecting the relevant interbank Eurodollar market
or otherwise, or if the Bank determines that the Eurodollar Rate
(less the applicable Margin) will not adequately and fairly
reflect the Bank"s cost of making or maintaining Eurodollar Rate
Advances, or if it shall become unlawful for the Bank to make or
maintain Eurodollar Rate Advances, then the Bank may suspend the
Borrower"s right to make Eurodollar Rate elections and all Loans
shall bear interest as provided in Section 2.04 or Section 2.06
until the Bank notifies the Borrower that such circumstances no
longer exist.  The Bank"s written notice setting forth its
determination as to the foregoing shall, if made on a reasonable
basis, be conclusive absent manifest error.

      Section 2.06.  Cost of Funds Rate Option.  Subject to the
terms and conditions set forth in this Agreement, any Term Loan
(in whole but not in part) may be made or maintained subject to a
Cost of Funds Rate election as below provided:

            (a)  A Cost of Funds Rate election shall be made in
writing (or, if by telephone, confirmed in writing) at least one
(1) Banking Day before the beginning of any Cost of Funds Interest
Period, specifying the Term Loan to be made or maintained as a
Cost of Funds Rate Advance and the first day of the Cost of Funds
Interest Period therefor.  In the absence of a timely Cost of
Funds Rate or Eurodollar Rate election with respect thereto, each
Term Loan shall bear interest as provided in Section 2.04.  Upon
the Borrower"s request, the Bank will quote a proposed Cost of
Funds Rate and will specify the time within which the Borrower may
elect to accept such offer by making a Cost of Funds Rate election
as provided above.  Any Cost of Funds Rate shall be offered and
determined by the Bank in its discretion and the Bank shall not be
deemed to make any representation or warranty with respect
thereto, the Borrower"s sole remedy, should it be dissatisfied
with such rate, being to decline to make a Cost of Funds Rate
election based thereon.
           
            (b)   Interest on all Cost of Funds Rate Advances
shall be due and payable monthly in arrears on or about the same
day of each calendar month numerically corresponding to the date
<PAGE>
<PAGE>
such Term Loan is made (e.g. for a Term Loan made on November 15,
interest payments will fall on or about the 15th day of each
succeeding month) and on the date of payment of the relevant Term
Note in full, at the applicable Cost of Funds Rate (computed on
the basis of a 360-day year for the actual number of days
elapsed).
            
            (c)   In the event that the Bank determines that
appropriate recognized sources of funding are not available to it
for a proposed Cost of Funds Interest Period or Cost of Funds Rate
Advance or that the "cost of funds" component of the Cost of Funds
Rate is unreasonably high, then the Bank may suspend the
Borrower"s ability to make Cost of Funds Rate elections and any
affected Term Loan shall bear interest as provided in Section 2.04
or Section 2.05 until the Bank notifies the Borrower that such
circumstances no longer exist.  The Bank"s written notice setting
forth its determination as to the foregoing shall, if made on a
reasonable basis, be conclusive absent manifest error.

      Section 2.07.  Notations Reflecting Loans.  The Borrower
hereby irrevocably authorizes the Bank to make or cause to be made
on the books of the Bank, at or following the time of making each
Loan and of receiving any payment of principal, an appropriate
notation reflecting such transaction and the then aggregate unpaid
principal balance of the Loans.  The amount so noted, and other
regular entries by the Bank on its books with respect to interest
and other charges, shall, absent manifest error, constitute
presumptive evidence as to the amount owed by the Borrower with
respect to principal of the Loans and with respect to interest and
other charges.

      Section 2.08.  Line of Credit Fee.  The Borrower shall pay
the Bank a fee (the "Line of Credit Fee") for the period
commencing on the date hereof to and including the Expiration
Date, or the earlier date of the termination of the Line of Credit
hereunder, at the applicable Line of Credit Fee Rate per annum
(computed on the basis of the actual number of days elapsed over a
360-day year) with respect to the Line of Credit Amount less (i)
the average daily outstanding Revolving Loans and (ii) the average
daily aggregate amount available to be drawn under outstanding
Letters of Credit.  The Line of Credit Fee shall be payable in
arrears on the first day of each calendar quarter commencing
January 1, 1998.

      Section 2.09.  Term Loan Facility Fee.  The Borrower shall
pay the Bank a fee (the "Term Loan Facility Fee") for the period
commencing on the date hereof to and including the Expiration
Date, or the earlier date of the termination of the Term Loan
Facility hereunder, at the applicable Term Loan Facility Fee Rate
per annum (computed on the basis of the actual number of days
elapsed over a 360-day year) with respect to the Term Loan
Facility Amount less the average daily outstanding Term Loans. 
The Term Loan Facility Fee shall be payable in arrears on the
first day of each calendar quarter commencing January 1, 1998.

      Section 2.10.  Security.  As security for Loans hereunder
and the Notes, the Borrower has granted to the Bank a continuing
security interest in and lien upon all its tangible and intangible
personal property and fixtures, including without limitation its
accounts receivable, inventory, equipment, general intangibles and
other Collateral pursuant to the Security Agreement.

                            ARTICLE III

                     LOAN PROCEEDS AND PAYMENTS

      Section 3.01.  Disbursement and Use of Loan Proceeds.  The
proceeds of each Revolving Loan or Term Loan shall be disbursed by
credit to the Borrower"s principal operating deposit with the Bank
unless otherwise requested in writing by the Borrower.  The
proceeds of each Revolving Loan will be used by the Borrower
solely for working capital purposes and the proceeds of each Term
Loan will be used by the Borrower solely for the purposes provided
in Section 2.02(b), as more particularly described to the Bank in
connection with the relevant borrowing request or otherwise.

      Section 3.02.  Payments.  All payments of interest,
principal and any other sum payable hereunder and/or the Notes
shall be made to the Bank at its Principal Office, in lawful
currency of the United States of America in immediately available
funds.  All payments received by the Bank after 2:00 p.m. on any
day shall be deemed received as of the next succeeding Banking
Day.  All monies received by the Bank hereunder shall be applied
first to fees, charges, costs and expenses payable to the Bank
under this Agreement, next to interest then accrued on account of
the Loans and only thereafter to principal of the Loans.

      Section 3.03.  Payment on Non-Banking Days.  Whenever any
payment to be made to the Bank hereunder or under the Note shall
be stated to be due on a day which is not a Banking Day (or, in
the case of any payment with respect to a Eurodollar Rate Advance,
a Eurodollar Banking Day), such payment shall be made on the next
succeeding Banking Day (or Eurodollar Banking Day), and interest
payable on each such date shall include the amount thereof which
shall accrue during the period of such extension of time.

      Section 3.04.  Net Payments.  All payments by the Borrower
hereunder and/or in respect of the Notes shall be made without
deduction, set-off or counterclaim, notwithstanding any claim
which the Borrower may now or at any time hereafter have against
the Bank.

      Section 3.05.  Charges Against Accounts.  The Bank may
charge any deposit account of the Borrower at the Bank with the
amount of all payments of interest, principal, fees and other sums
due, from time to time, under this Agreement and/or the Notes, and
will thereafter notify the Borrower of the amount so charged.  The
failure of the Bank to charge any account or to give any such
notice shall not affect the obligation of the Borrower to pay
interest, principal or other sums as provided herein or in the
Notes.  For purposes of this Section 3.05, the term "Bank" shall
include any affiliate of the Bank so long as the Borrower
maintains deposits with any such bank.

      Section 3.06.  Prepayment.  The Borrower may repay Revolving
Loans (in whole or in part) and Term Loans (in whole but not in
part) that bear interest based on the Prime Rate at any time;
provided that there shall also be paid therewith all interest
accrued with respect thereto.  Principal prepaid with respect to
Revolving Loans, and principal repaid or prepaid with respect to
Term Loans, may, subject to the terms and conditions set forth in
this Agreement, be reborrowed.  If any Revolving Loan or portion
of the Revolving Loans bears interest at a Eurodollar Rate or if
anyTerm Loan bears interest at a Eurodollar Rate or a Cost of
<PAGE>
<PAGE>
Funds Rate, and the Bank in its sole discretion should determine
that current market conditions can accommodate a prepayment
request, the Borrower shall have the right at any time and from
time to time to prepay the same in whole (but not in part);
provided that there shall also be paid therewith all interest
accrued with respect thereto and the Borrower shall pay to the
Bank a yield maintenance fee in an amount computed as follows: 
The current rate for United States Treasury securities (bills on a
discounted basis shall be converted to a bond equivalent) with a
maturity date closest to the last day of the current Eurodollar
Interest Period with respect thereto or the Term Loan Maturity
Date of such Term Loan, as the case may be, shall be subtracted
from the "cost of funds" component of the Eurodollar Rate or Cost
of Funds Rate in effect at the time of prepayment.  If the result
is zero or a negative number, there shall be no yield maintenance
fee.  If the result is a positive number, then the resulting
percentage shall be multiplied by the amount of the principal
balance being prepaid.  The resulting amount shall be divided by
360 and multiplied by the number of days remaining until the
relevant Eurodollar Interest Period expiration or Term Loan
Maturity Date.  Said amount shall be reduced to present value
calculated by using the number of days remaining until the
Eurodollar Interest Period expiration or Term Loan Maturity Date
and using the above-referenced United States Treasury security
rate and the number of days remaining until the Eurodollar
Interest Period expiration or Term Loan Maturity Date.  The
resulting amount shall be the yield maintenance fee due to the
Bank upon prepayment of a Revolving Loan or portion of the
Revolving Loans when bearing interest at a Eurodollar Rate or Term
Loan when bearing interest at a Eurodollar Rate or Cost of Funds
Rate.

      If by reason of an Event of Default the Bank elects to
declare the Loans to be immediately due and payable, then any
yield maintenance fee with respect to any Loan shall become due
and payable in the same manner as though the Borrower had
exercised such right of prepayment.

      Section 3.07.  Changed Circumstances; Increased Costs.  The
Borrower acknowledges that the Bank has offered to the Borrower
loan pricing reflected in this Agreement and the Notes taking into
account existing costs of compliance with certain U.S.
governmental regulatory requirements, notably FDIC deposit
insurance assessments applicable to Bank deposits, reserves that
are required to be maintained by the Bank under Federal Reserve
Board regulations and regulators" requirements applicable to the
Bank and its parent holding company with respect to capital
adequacy.  The Borrower agrees that if any change in the
applicable Federal regulations or in the interpretation thereof by
the relevant agencies, or compliance with any guideline or request
of any such agency (whether or not having the force of law),
increases the Bank"s costs in respect of loans or lines of credit
such as provided for herein (or reduces the rate of return on
capital of the Bank or its holding company), the Bank may at its
option adjust the loan pricing reflected in this Agreement and the
Notes, including without limitation any Cost of Funds Rate or
Eurodollar Rate then in effect, to compensate therefor, in which
event the Bank shall provide written notice to the Borrower
setting forth in reasonable detail the basis for and calculation
of such increased cost or reduced rate of return (but failure to
provide such notice shall not affect the parties" rights and
obligations).  The Bank"s written notice setting forth its
determination as to the foregoing shall, if made on a reasonable
basis, be conclusive absent manifest error.
<PAGE>
<PAGE>
      Section 3.08.  Interest Rate Reduction in Certain
Circumstances.  All agreements between the Borrower, any guarantor
of the Borrower"s obligations and the Bank are hereby expressly
limited so that in no contingency or event whatsoever, whether by
reason of acceleration of maturity of the indebtedness evidenced
hereby or by the Notes or otherwise, shall the amount paid or
agreed to be paid to the Bank for the use or the forbearance of
such indebtedness exceed the maximum permissible under applicable
law.  As used herein, the term "applicable law" shall mean the law
in effect as of the date hereof; provided that in the event there
is a change in the law which permits a higher permissible rate of
interest, then this Agreement and the Notes shall be governed by
such new law as of its effective date.  In this regard, it is
expressly agreed that it is the intent of the Borrower and the
Bank in the execution, delivery and acceptance of this Agreement
and the Notes to contract in strict compliance with the laws of
the Commonwealth of Massachusetts from time to time in effect.  
If, under or from any circumstances whatsoever, fulfillment of any
provision hereof or of the Notes or any other document executed in
connection herewith at the time performance of such provision
shall be due, shall involve transcending the limit of such
validity prescribed by applicable law, then the obligation to be
fulfilled shall automatically be reduced to the limits of such
validity, and if under or from circumstances whatsoever the Bank
should ever receive as interest any amount which would exceed the
highest lawful rate, such amount which would be excessive interest
shall be applied to the reduction of the principal balance
evidenced hereby and not to the payment of interest.  This
provision shall control every other provision of all agreements
between the Borrower, any guarantor of the Borrower"s obligations
and the Bank.

incorporation and the percentage of its outstanding capital stock
owned by the Borrower or any Subsidiary.  Each Subsidiary is a
corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation and has
all requisite corporate power to own and operate its properties
and to carry on its business as now conducted and as proposed to
be conducted.  All of the outstanding capital stock of each

pledge, security interest, option or other encumbrance.

      (c)   Qualification.  The Borrower and each Subsidiary is

necessary in order to carry out its business as now conducted and
as proposed to be conducted.

      (d)   Due Authorization, etc.  The execution, delivery and
performance of this Agreement, the Note, the Security Agreement
and the other documents required to be executed by the Borrower
pursuant hereto have been duly authorized by all necessary
corporate action, will not require the consent of any third party,
and will not conflict with, violate the provisions of, or cause a
default or constitute an event which, with the passage of time or
giving of notice or both, could constitute an event of default on
the part of the Borrower under any contract, agreement, law, rule,
order, ordinance, franchise, instrument or other document or under
any provision of the Articles of Organization or By-Laws of the
Borrower, or result in the imposition of any Lien on any property
or assets of the Borrower other than in favor of the Bank.  This
Agreement and the other documents delivered to the Bank by the
Borrower pursuant hereto (including, without limitation, the Notes
and the Security Agreement) are the legal, valid and binding
obligations of the Borrower, enforceable in accordance with their
respective terms.

      (e)   Litigation.  There are no actions, suits, proceedings
or investigations pending or, to the knowledge of the Borrower,
threatened, anticipated or contemplated (nor, to the knowledge of
the Borrower, any basis therefor) against or affecting the
<PAGE>
<PAGE>
Borrower or, to the knowledge of the Borrower, any officer of the
Borrower before any court or governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign,
which could prevent or hinder the consummation of the transactions
contemplated hereby or call into question the validity of this
Agreement, the Notes, the Security Agreement or any other
instrument provided for or contemplated by this Agreement or any
action taken or to be taken in connection with the transactions
contemplated hereby or thereby or which in any single case or in
the aggregate might result in any material adverse change in the
business, prospects, condition, affairs or operation of the
Borrower or any material impairment of the right or ability of the
Borrower to carry on its operations as now conducted or proposed
to be conducted.

      (f)   No Violation.  The Borrower is not in violation of
(i) any term of its Articles of Organization or By-Laws, as now in
effect, (ii) any term of any mortgage, indenture or judgment,
decree or order, any other instrument, contract or agreement
binding on the Borrower or its property or (iii) to the knowledge
of the Borrower, any term of any statute, ordinance,
administrative determination, or governmental rule or regulation
applicable to it.

      (g)   Taxes.  The Borrower has filed proper and, to the best
of its knowledge, accurate federal, foreign, state and local tax
returns, reports and estimates for all years and periods for which
any such returns, reports or estimates were required to be filed
and has paid all taxes, assessments, impositions, fees and other
governmental charges required to be paid in respect of the periods
covered by any such returns, reports or estimates.  There are in
effect no waivers of applicable statutes of limitations for
federal, state or local taxes for any period.  The Borrower is not
delinquent in the payment of any tax, assessment or governmental
charge and has not requested any extension of time within which to
file any tax return, which return has not since been filed, and no
deficiencies for any tax, assessment or governmental charge have

of the Borrower and its Subsidiaries are adequate in the opinion
of the Borrower.

      (h)   Legal Compliance.  The Borrower is, to the best of its
knowledge, in compliance with all requirements of law, federal,
state and local, and all requirements of all governmental bodies
or agencies having jurisdiction over it, the conduct of its
business, the use of its properties and assets, and all premises

and authorizations needed for the conduct of its business and the
use of its properties and all premises occupied by it, as now
conducted, owned and used or as proposed to be conducted, owned

heretofore complied with, from any federal, state or local
authority or any insurance or inspection body that any of its
properties, facilities, equipment or business procedures or
practices fails to comply with any applicable law, ordinance,
regulation, building or zoning law or any other requirement of any
such authority or body.  No authorization, consent, approval,
license, exemption of or filing or registration with any court or
governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, is or will be necessary to

present intention of acquiring any margin stock; and no part of
the proceeds of the Notes (including without limitation
Acquisition/WC Loans) will be used, directly or indirectly, to
purchase or carry any margin stock or to extend credit to others
for the purpose of purchasing or carrying any margin stock or in
any other manner which would involve a violation of Regulation U,
Regulation T, Regulation X or any other regulation of the Board of
Governors of the Federal Reserve System or the SEC.  The Borrower

     (k)   Financial Statements.  The Borrower"s Consolidated
financial statements for its fiscal year ended March 31, 1997, and
its interim Consolidated financial statements for the fiscal period
ended September 30, 1997, heretofore delivered to the Bank, are
accurate and complete, fairly present the financial condition of
the Borrower and its Subsidiaries as at the respective dates
thereof and for the periods covered thereby (subject, in the case
of such interim statements, to normal year-end adjustments and
inclusion of notes and schedules), and were prepared in accordance
with GAAP consistently applied throughout such fiscal periods.  The
Borrower and its Subsidiaries have no material liability,
contingent or otherwise, that is not disclosed or reflected in such
financial statements or any notes thereto and which, in accordance
with GAAP, is required to be disclosed or reflected therein and
could materially adversely affect the financial condition of the
Borrower.  Since the date of the financial statements most recently
delivered pursuant to this Agreement (including those referred to
above):  there has been no material adverse change in the business,
assets or condition, financial or otherwise, of the Borrower or of
any of its Subsidiaries; neither the business, condition or
operations of the Borrower or any such Subsidiary nor any of their
respective properties or assets have been materially adversely
affected as the result of any legislative or regulatory change
known to the Borrower, any revocation or change in any franchise,
license or right to do business, or any other event or occurrence,
whether or not insured against; neither the Borrower nor any such
Subsidiary has experienced any material controversy or problem with
its customers or suppliers or with its employees or with any labor
organization; and neither the Borrower nor any such Subsidiary has
entered into any material transaction other than in the ordinary
course of its business.

      (l)   ERISA.  The Borrower has no accumulated funding
deficiency within the meaning of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"); nor does it have any
<PAGE>
<PAGE>
liability to the Pension Benefit Guaranty Corporation ("PBGC")
established under ERISA (or any successor thereto) in connection
with any employee benefit plan or multiemployer plan (or other
class of benefit which the PBGC has elected to insure); there have
been no "reportable events" or "prohibited transactions" with
respect to any such plan, as those terms are defined in Section
4043 of ERISA and Section 4975 of the Internal Revenue Code of
1986, as amended (the "Code"), respectively; and each such plan
has been administered in material compliance with the applicable
provisions of ERISA and the Code.  The Borrower has no pension,
profit-sharing, stock option, insurance or similar plan providing
for deferred compensation or other benefits to any director,
officer or employee except as set forth on Schedule 5.01(l)
hereto.

      (m)   Head Office.  The chief executive office and principal
place of business of the Borrower is located at 360 Second Avenue,
Waltham, MA  02154.  Schedule 5.01(m) sets forth a list of all of
the facilities and locations of the Borrower and its Subsidiaries.

      (n)   Contracts.  Neither the Borrower nor any of its
Subsidiaries is a party to any contract or agreement, the terms of
which now has or, as far as can be foreseen, may have a material
adverse effect on the financial condition, business or properties
of the Borrower or any of its Subsidiaries.  There exist no
defaults by any party under any contract or agreement between
either Borrower and any other Person which, singly or in the
aggregate, if not promptly cured, may have a material adverse
effect on the financial condition, business or properties of the
Borrower or any of its Subsidiaries.

      (o)   Statements Not Misleading.  Neither this Agreement and
the Security Agreement, nor the financial statements referred to
herein, nor any certificate delivered pursuant to this Agreement,
nor any other agreement, document, certificate or written
statement furnished to the Bank or to the Bank"s counsel by or on
behalf of the Borrower in connection with the transactions
contemplated by this Agreement contains any untrue statement of a
material fact or omits to state a material fact necessary in order
to make the statements contained herein or therein not misleading. 
There is no fact within the knowledge of the Borrower"s executive
officers which has not been disclosed herein or in writing to the
Bank and which materially adversely affects, or in the future in
its opinion may, insofar as the Borrower can no foresee,
materially adversely affect the business, properties, assets or
condition, financial or other, of the Borrower or any of its
Subsidiaries.
