"Company") condensed  consolidated financial position as of April 1, 1995 and
its condensed consolidated results of operations and cash flows for the periods
ended April 1, 1995 and April 2, 1994.  The results of operations for the three
months ended April 1, 1995 are not necessarily indicative of the results to be
expected for the entire year ending December 31, 1995.  Certain information
reported in the prior year has been reclassified to conform to the 1995
presentation.

   The Company's principle accounting policies are set forth in the financial
statements for the year ended December 31, 1994 and notes thereto, contained in
the Company's Annual Report filed with the Securities and Exchange Commission.


Note 2 - Investments

   Under Statement of Financial Accounting Standards No. 115, the Company's
investments, which consisted entirely of debt securities (the "securities"),
were classified as available-for-sale.  These securities mature at various dates
through the year 1996.
 
   As of April 1, 1995, the securities' gross unrealized holding loss was
approximately $249,000. The unrealized holding loss of approximately $169,000,
net of the tax effect, was reported as a separate component of stockholders'
equity.  The Company has determined that the unrealized holding loss is not a
permanent impairment of the fair value of its investments.  During the three
months ended April 1, 1995, the Company did not sell any of its securities prior
to maturity.


Note 3 - Inventories

   The components of inventories were as follows (in thousands):

Note 4 - Legal Contingencies

  On July 1, 1993 and July 30, 1993, individuals purporting to represent a class
of persons who purchased Acuson common stock during the period between October
24, 1990, and July 22, 1992, filed two separate, but related, actions against
the Company and twelve of its officers and one former officer in the Federal
District Court for the Northern District of California alleging that the
defendants' statements about the Company were incomplete or inaccurate, in
violation of Federal securities laws.  Plaintiffs seek damages in an unspecified
amount, as well as equitable relief or injunctive relief and attorneys' fees,
experts' fees and costs.

                                       4

  On September 14, 1994, the Company filed an action in the United States
District Court for the Northern District of California against Advanced
Technology Laboratories, Inc. ("ATL") of Bothell, Washington.  In the action,
the Company accuses ATL of infringing U.S. Letters Patent No. 4,058,003 for
"Ultrasonic Electronic Lens with Reduced Delay Range," a patent licensed
exclusively to the Company.  In addition, the Company seeks a declaration that
it infringes no valid claim of four ATL patents:  U.S. Letters Patent No.
4,543,960 for "Transesophageal Echocardiography Scanhead," No. 5,050,610 for
"Transesophageal Ultrasonic Scanhead," No. 5,207,225 for "Transesophageal
Ultrasonic Scanhead," or No. 5,226,422 for "Transesophageal Echocardiography
Scanner with Rotating Image Plane."  No dollar amount is specified as damages in
the Company's action, but the complaint seeks an accounting for damages, treble
damages and an assessment of interests and costs against ATL.  In addition, the
Company is informed that, in August 1994, ATL filed an action against the
Company in the United States District Court for the Western District of
Washington, in which ATL sought a declaration that it infringes no valid claim
of U.S. Letters Patent No. 4,058,003.  On October 31, 1994, ATL amended that
action and added claims accusing the Company of infringing U.S. Patent Nos.
4,543,960; 5,050,610; 5,207,225; and 5,226,422.  No dollar amount is specified
as damages in ATL's action, but the complaint seeks an injunction against
alleged infringement, an accounting for damages, treble damages, and an
assessment of interest and costs against the Company.

  On October 27, 1994, the Company was sued in Ghent, Belgium, by Cormedica NV,
in connection with the Company's termination of its distributor relationship
with Cormedica.  In the suit, Cormedica seeks indemnities and damages in the
amount of approximately $2.5 million.

  The Company intends to defend each of these suits vigorously.  Management
believes that the ultimate outcome of any of these matters will not have a
material adverse effect on the Company's financial condition.

ITEM 2
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


Results of Operations

   Net sales for the quarter ended April 1, 1995, were $88.0 million compared to
$92.8 million in the quarter ended April 2, 1994.  The change in revenue was
primarily because of a decrease in domestic product revenue.  The Company's
average unit selling prices were lower in this quarter as a result of an
increase in sales of lower-priced configurations and intense competitive pricing
pressures.  Worldwide service revenue increased 6.5% to $19.3 million from $18.1
million in the quarter ended April 2, 1994, primarily due to growing service
contract revenue from a larger base of installed systems.  Geographically,
international revenue increased to $32.8 million, totalling 37.2% of the
Company's sales as compared to 27.9% in the comparable 1994 period.

   The Company believes that the trends of health-care-provider consolidation,
medical cost containment and intense competitive pressures which existed in
1994, will continue into 1995.  The Company believes that future revenues may
continue to be impacted by these uncertainties, especially in the domestic
ultrasound market.  Although portions of the international ultrasound markets
are experiencing some economic recovery, it is uncertain whether this is
temporary or permanent.

   The gross profit for the first quarter of 1995 was 54.0% of net sales,
compared to 57.0% in the first quarter of 1994.  The percentage change was
primarily a reflection of reduced product prices and increased sales of lower-
priced product configurations, partially offset by improvement in service
margins.

   Selling, general and administrative costs were $27.3 million in the quarter
ended April 1, 1995, as compared to $26.6 million in the prior year's period.
As a percentage of sales, such expenses in the first three months in 1995
totalled 31.0% of net sales compared to 28.7% in 1994.  Dollar spending
increased primarily due to international expenses supporting the increase in
international sales.

   Product development costs in the first quarter of 1995 totalled $18.1 million
or 20.5% of net sales, compared to $17.3 million or 18.7% of net sales in the
first quarter of 1994.  The increase in product development expense results from
continuing investment in multiple new product development programs.

   The provision for income taxes was $0.9 million in the first quarter of 1995
versus $3.5 million in the first quarter of 1994. The effective tax rate for the
three months ended April 1, 1995 was 29% versus 35% in the same period in the
prior year.

Liquidity and Capital Resources

   The Company's cash and short-term investments balance has increased $7.3
million during the three months ended April 1, 1995 to $74.4 million.  During
the quarter, the Company generated $12.9 million in cash from operations, as
compared to the first quarter of 1994 when operations generated $11.5 million in
cash.  Also, in the first quarter of 1994, the Company sold its lease portfolio
generating an additional $21.6 million in cash.  The Company's investing and
financing activities for the three months ended April 1, 1995 have used $1.1
million.  Included in the financing activities was $3.5 million raised through
employee participation in the Company's stock option and stock purchase plans,
compared to $2.2 million during the first quarter of 1994.

   In 1993, the Board of Directors authorized the repurchase of 4,000,000 shares
of common stock over an unspecified period of time.  During the first quarter
the Company repurchased 450,000 shares, for a total repurchase of 817,700 shares
to date toward the Board authorization.  As of April 1, 1995,  there were
28,785,008 shares of Acuson common stock outstanding.

   At April 1, 1995, the Company's working capital totalled $135.3 million.  The
Company also has a revolving unsecured credit facility for $50 million which is
in effect through March 1997.  No compensating balances are required and the
full amount is available under this credit facility.  There were no draws on
this line of credit during the quarter.

   Based on its current operating plan, the Company believes that the liquidity
provided by its existing cash and short-term investments, the borrowing
arrangements described above, and cash generated from operations will be
sufficient to meet the Company's operating and capital requirements for fiscal
1995.

other lending institutions listed on Schedule 1 hereto and THE FIRST NATIONAL
BANK OF BOSTON, as agent for itself and such other lending institutions (in such
capacity, the "Agent").

         WHEREAS, pursuant to a Credit Agreement dated as of July 21, 1992 (as
amended from time to time, the "Original Credit Agreement"), by and among the
Company, certain of the Banks (as hereinafter defined) and the Agent, certain
Banks made available revolving credit loans for general corporate and working
capital purposes; and

         WHEREAS, the Company has requested certain modifications to the
Original Credit Agreement and the Banks are willing to make such modifications
on the terms and conditions set forth herein;

         NOW, THEREFORE, the Company, the Agent and the Banks agree that on the
Closing Date (as hereinafter defined) the Original Credit Agreement is hereby
amended and restated in its entirety as set forth herein.


                            SECTION 1.  DEFINITIONS

         1.1 DEFINED TERMS. All terms defined in this Agreement shall have the
defined meanings when used herein or in any certificate, report, or other
document made or delivered pursuant to this Agreement, unless the context
otherwise requires. The following terms shall have the following meanings:

         "Adjustment Date" shall mean the first day of the Company's fiscal
month immediately following the month in which a Compliance Certificate is to be
delivered by the Company pursuant to Section 8.6C.

         "Agreement" shall mean this Amended and Restated Credit Agreement,
including the schedules and exhibits hereto, as originally executed and as the
same may from time to time be amended, restated or supplemented.

         "Applicable Margin" shall mean for each period commencing on an
Adjustment Date through the date immediately preceding the next Adjustment Date
(each a "Rate Adjustment Period"), the applicable margin set forth below with
respect to the Company's Leverage Ratio, as determined for the fiscal period of

</TABLE>

         Notwithstanding the foregoing, from the Closing Date through the first
Adjustment Date, the Applicable Margin shall be the highest Applicable Margin
unless the Company delivers a Compliance Certificate to the Agent on the
Effective Date demonstrating a Leverage Ratio which would entitle the Company to
a lower Applicable Margin.  In addition, notwithstanding the foregoing but
subject to the balance of this paragraph, if the Company fails to deliver any
Compliance Certificate pursuant to Section 8.6C hereof then, for the period
commencing on the next Adjustment Date to occur subsequent to such failure
through the date immediately following the date on which such Compliance
Certificate is delivered, the Applicable Margin shall be the highest Applicable
Margin set forth above.  In addition, notwithstanding anything to the contrary
contained herein, if the Borrower delivers a Compliance Certificate for the
preceding fiscal quarter and such Compliance Certificate evidences a Leverage
Ratio for such quarter which would indicate that the Applicable Margin (a)
should be calculated at a higher amount during the current fiscal quarter, the
Applicable Margin shall be adjusted upward retroactively on the basis of the
higher Leverage Ratio to the Applicable Margin which would have otherwise been
applicable pursuant to this definition, and the Company shall pay to the agent
for the pro rata account of the Banks within five (5) Business Days after notice
thereof all interest accrued but unpaid with respect to the Loans using the
adjusted Applicable Margin for any portion of the current fiscal quarter as to
which a portion of such interest has been paid; and (b) should be calculated at
a lower amount during the fiscal quarter, the Applicable Margin shall be
adjusted downward retroactively on the basis of the lower Leverage Ratio to the
Applicable Margin which would otherwise be applicable to this definition, and
the Banks shall pay to the Agent within five (5) Business Days after notice
thereof and the Agent shall pay to the Company within one (1) Business Day after
receipt thereof all amounts paid by the Company in excess with respect to the
Loans using the adjusted Applicable Margin for any portion of the current fiscal
quarter as to which a portion of such interest has been paid.

13.1.

SECTION 2. REVOLVING CREDIT LOANS

     2.1  REVOLVING CREDIT COMMITMENT.

          A. Subject to the terms and conditions of this Agreement, each Bank
severally agrees to make Revolving Credit Loans to the Company at any one time
equal to such Bank's Commitment from the date of this Agreement to and including
the Revolving Credit Loan Maturity Date as at such time and in such amounts as
the Company may request, which amounts may be borrowed, repaid and reborrowed
subject to the limitations set out herein, provided that the sum of the
outstanding amount of the Revolving Credit Loans, (after giving effect to all
amounts requested) shall not at any time exceed the Total Commitment.

          B. Each Loan shall be in a minimum aggregate principal amount of
$1,000,000 and in multiples of $100,000.

          C. The obligation of the Company to repay to the Banks the principal
of the Revolving Credit Loans advanced by each Bank and interest thereon shall
be evidenced by a promissory note (the "Revolving Credit Note") dated as of the
Closing Date and completed with appropriate insertions. One Revolving Credit
Note shall be payable to the order of each Bank in a principal amount equal to
such Bank's Commitment or, if less, the outstanding amount of all Revolving
Credit Loans made by such Banks, plus interest accrued thereon, as set forth
below. The Company irrevocably authorizes each Bank to make or cause to be made,
at or about the time of the Drawdown Date of any Revolving Credit Loan or at the
time of receipt of any principal on such Bank's Revolving Credit Note, an
appropriate notation on such Bank's Revolving Credit Note Record reflecting the
making of such Revolving Credit Loan or, as the case may be, the receipt of such
payment. The outstanding amount of the Revolving Credit Loans set forth on such
Bank's Revolving Credit Note Record shall be prima facie evidence of the
principal amount thereof owing and unpaid to such Bank, but the failure to
record, or any error in so recording, any such amount on such Bank's Revolving
Credit Note Record shall not limit or otherwise affect the obligations of the
Company hereunder or under any Revolving Credit Note to make payments of
principal of or interest on any Revolving Credit Note when due.

     2.2 RATE DESIGNATION. The Company shall designate each Revolving Credit
Loan requested hereunder as a Domestic Rate Loan or a Eurodollar Rate Loan in
the notice given to the Agent in accordance with Section 2.6 hereof.

     2.3 DOMESTIC RATE REVOLVING LOANS. Principal with respect to each Revolving
Credit Loan bearing interest at the Domestic Rate shall be due and payable on
the Revolving Credit Loan Maturity Date. Except as set forth in Section 4.6,
each Revolving Credit Loan bearing interest at the Domestic Rate shall bear
interest upon the unpaid principal balance of such Revolving Credit Loan from
the Drawdown Date of such Revolving Credit Loan and ending on the last day of
the Interest Period with respect thereto at a fluctuating rate per annum equal
to the Domestic Rate plus the Applicable Margin. The Company promises to pay
interest on each Revolving Credit Loan monthly in arrears on the first day of
each month, commencing with the first such day to occur after each Revolving
Credit Loan is made hereunder, and on the Revolving Credit Loan Maturity Date,
on which date all interest remaining unpaid shall be due and payable.
<PAGE>
 
                                      -9-

     2.4 EURODOLLAR RATE LOANS. Each Interest Period for a Revolving Credit Loan
bearing interest at the Eurodollar Rate shall be selected by the Company,
provided that no such term extends beyond the Revolving Credit Loan Maturity
Date. Except as set forth in section 4.6, each Revolving Credit Loan bearing
interest at the Eurodollar Rate shall bear interest at a rate per annum equal to
the Eurodollar Rate plus the Applicable Margin for such period. Principal with
respect to each Eurodollar Rate Loan shall be due and payable on the Revolving
Credit Loan Maturity Date. The Company promises to pay interest on each
outstanding Eurodollar Rate Loan at the end of such Interest Period, provided
that if the Interest Period is longer than three months, then interest shall be
payable on the date that is three months from the first day of such Interest
Period, and, in addition, the last day at of such Interest Period.

     2.5 LOAN ACCOUNT. Each Bank will maintain a separate account on its books
for the Company (the "Loan Account") on which will be recorded, in accordance
with such Bank's customary accounting practice, (a) all Revolving Credit Loans
made by such Bank to the Company, (b) all payments of such Revolving Credit
Loans made to such Bank, and (c) all other charges and expenses properly
chargeable to the Company hereunder. The debit balance of the Loan Account of
each Bank shall reflect the amount of the Company's indebtedness for Revolving
Credit Loans from time to time to such Bank hereunder. So long as any Revolving
Credit Loans are outstanding, each Bank shall deliver written statements to the
Company from time to time (but no less frequently than quarterly) reflecting the
amount of such indebtedness and such statements shall, in the absence of
manifest error or any written statement of objection delivered by the Company to
such Bank within five (5) Business Days after the Company's receipt thereof,
constitute prima facie evidence of the indebtedness for Revolving Credit Loans
of the Company to such Bank hereunder as of the date of such statement.

     2.6 SPECIAL NOTICE REQUIREMENTS. Each Revolving Credit Loan bearing
interest at the Domestic Rate shall be made on a Business Day, and each
Revolving Credit Loan bearing interest at the Eurodollar Rate shall be made on a
Eurodollar Business Day. Irrevocable notice in the form of Exhibit A hereto (a
"Notice of Borrowing") shall be given by the Company to the Agent as follows:

          A.   For a Domestic Rate Loan, notice must be received by the Agent by
11:00 a.m., California time, one Business Day preceding the day on which such
Domestic Rate Loan is to be made; and

          B.   For a Eurodollar Rate Loan, notice must be received by the Agent
by 11:00 a.m., California time, three (3) Eurodollar Business Days preceding the
day on which such Eurodollar Rate Loan is to be made.

The Agent will promptly notify each Bank as to the content of each Notice of
Borrowing. Not later than 12:00 noon, Boston time, on the Drawdown Date of such
borrowing, each Bank shall make available its pro rata share of such borrowing
in immediately available funds, by wiring the proceeds thereof in accordance
with the instructions contained in the Notice of Borrowing.

The Agent may, unless notified to the contrary by any Bank prior to a Drawdown
Date, assume that such Bank has made available to the Agent on such Drawdown
Date the amount of such Bank's Commitment Percentage of the Revolving Credit
Loans to be made on such Drawdown Date, and the Agent may (but it shall not be
required to), in reliance upon such assumption, make available to the Company a
corresponding amount. If any Bank makes available to the Agent such amount on a
date after such Drawdown Date, such Bank shall pay to the Agent on demand an
amount equal to the product of (a) the average computed for the period referred
to in clause (c) below, of the weighted average interest rate paid by the Agent
for federal funds acquired by the Agent during each day included in such period,
times (b) the amount of such Bank's Commitment Percentage of such Revolving
Credit Loans, times (c) a fraction, the numerator of which is the number of days
that elapse from and including such Drawdown Date to the date on which the
amount of such Bank's Commitment Percentage of such Revolving Credit Loans shall
become immediately available to the Agent, and the denominator of which is 365.
A statement of the Agent submitted to such Bank with respect to any amounts
owing under this paragraph shall be prima facie evidence of the amount due and
owing to the Agent by such Bank. If the amount of such Bank's Commitment
Percentage of such Revolving Credit Loans is not made available to the Agent by
such Bank within three (3) Business Days following such Drawdown date, the Agent
shall be entitled to recover such amount from the Company on demand, with
interest thereon at the rate per annum applicable to the Revolving Credit Loans
made on such Drawdown date.

     2.7  PREPAYMENT.  Upon written notice, or telephonic notice promptly
confirmed in writing, received by the Agent on the Business Day prior to the day
of such prepayment, the Company shall have the right to make prepayments of any
Revolving Credit Loan, without penalty or premium, provided that:

          A.  Each partial prepayment shall be in an amount of $100,000 or a
multiple thereof or the outstanding balance of such Revolving Credit Loan if the
outstanding balance is $1,000,000 or less; and

          B.  Eurodollar Rate Loans may be prepaid in accordance with the
provisions of Section 2.7A above only upon payment to the Agent of a prepayment
fee computed in accordance with the following formula:

                              L = (R - T) x P x D
                                  ---------------  
                                         360

          L =  amount payable to the Agent

          R =  interest rate on such Revolving Credit Loan being prepaid

          T =  Eurodollar Rate in effect on the date of prepayment for new
               Revolving Credit Loans made for the remaining term of such
               Revolving Credit Loan being prepaid and in a principal amount
               equal to the amount prepaid

          P =  the amount of principal prepaid

          D =  the number of days remaining in the term of such Revolving Credit
               Loan being prepaid as of the date of such prepayment

The Company shall pay such amount upon presentation by the Agent of a statement
setting forth the amount and the Agent's calculation thereof pursuant hereto,
which statement shall be deemed true and correct absent manifest error.

     2.8  COMMITMENT FEES.  The Company shall pay to the Agent for the account
of each Bank in accordance with their respective Commitment Percentages a
commitment fee equal to the Fee Amount on the average daily amount during each
calendar quarter or portion thereof from the Closing Date to the Revolving
Credit Loan Maturity Date by which the Total Commitment exceeds the outstanding
amount of Revolving Credit Loans during such calendar quarter.  Such commitment
fee shall be due and payable quarterly in arrears on the last day of each
calendar quarter, commencing with the first such day to occur after the Closing
Date, and on the Revolving Credit Loan Maturity Date or any earlier date on
which the Commitments are terminated.  Such fees shall be computed on the basis
of a 360-day year and actual days elapsed.
<PAGE>
 
                                      -11-

     2.9 REDUCTION OF COMMITMENT. Upon written notice, or telephonic notice
promptly confirmed in writing, received by each Bank five (5) Business Days
prior to the effective date of such reduction, the Company may at any time
wholly terminate the Total Commitment, or from time to time permanently reduce
in multiples of $1,000,000 the amount thereof. Each such reduction shall reduce
the Commitment of each Bank pro rata in accordance with their respective
Commitment Percentages of the amount specified in such notice. Said notice shall
be irrevocable unless all the Banks consent in writing to its revocation prior
to the effectiveness of such reduction. Upon the effective date of any such
reduction of Commitments, the Company shall make payments of principal to the
Agent for the accounts of the Banks necessary to reduce the amount outstanding
under the Revolving Credit Loans made pursuant to the Total Commitment to an
amount not exceeding the Total Commitment, as reduced. Upon the effective date
of any such reduction or termination, the Company shall pay to the Agent for the
respective accounts of the Banks the full amount of any commitment fee then
accrued on the amount of the reduction. No reduction of the Commitment may be
reinstated unless all the Banks consent in writing to its revocation prior to
the effectiveness of such reduction.

     2.10.  CONVERSION OPTIONS.

          A.
The Company may elect from time to time to convert any outstanding Revolving
Credit Loan to a Revolving Credit Loan of another Type, provided that (i) with
respect to any such conversion of a Revolving Credit Loan to a Domestic Rate
Loan, the Company shall give the Agent at least two (2) Business Days prior
written notice of such election; (ii) with respect to any such conversion of a
Eurodollar Rate Loan into a Revolving Credit Loan of another Type, such
conversion shall only be made on the last day of the Interest Period with
respect thereto; (iii) with respect to any such conversion of a Domestic Rate
Loan to a Eurodollar Rate Loan, the Company shall give the Agent at least three
(3) Eurodollar Business Days prior written notice of such election and (iv) no
Loan may be converted into a Eurodollar Rate Loan when any Default or Event of
Default has occurred and is continuing.  On the date on which such conversion is
being made each Bank shall take such action as is necessary to transfer its
Commitment Percentage of such Revolving Credit Loans to its domestic lending
office or its Eurodollar Lending Office, as the case may be.  All or any part of
outstanding Revolving Credit Loans of any Type may be converted as provided
herein, provided that partial conversions shall be in an aggregate principal
amount of $1,000,000 or a whole multiple thereof.  Each Conversion Request
relating to the conversion of a Revolving Credit Loan to a Eurodollar Rate Loan
shall be irrevocable by the Company.

          B.
Any Eurodollar Rate Loan may be continued as such upon the expiration of an
Interest Period with respect thereto by compliance by the Company with the
notice provisions contained in Section 2.10A; provided that no Eurodollar Rate
Loan may be continued as such when any Default or Event of Default has occurred
and is continuing, but shall be automatically converted to a Domestic Rate Loan
on the last day of the first Interest Period relating thereto ending during the
continuance of any Default or Event of Default of which the officers of the
Agent active upon the Company's account have actual knowledge.  In the event
that the Company fails to provide any such notice with respect to the
continuation of any Eurodollar Rate Loan as such, then such Eurodollar Rate Loan
shall be automatically converted to a Domestic Rate Loan on the last day of the
Interest Period relating thereto.  Each Domestic Rate Loan shall automatically
continue as a Domestic Rate Loan unless notice is given by the Company to the
Agent electing a Loan of another Type as provided in Section 2.10A.  The Agent
shall notify the Banks promptly when any such automatic conversion contemplated
by this Section 2.10 is scheduled to occur.

SECTION 3.  THE TERM LOAN

     3.1 CONVERSION OF REVOLVING CREDIT LOANS; THE TERM LOAN. Subject to the
terms and conditions hereinafter set forth, including, without limitation, the
satisfaction of the conditions set forth in Section 5.2 hereof, on the
Conversion Date the aggregate amount of the outstanding Revolving Credit Loans
shall be converted into a Term Loan in an aggregate principal amount equal to
the aggregate outstanding principal balance of the Revolving Credit Loans on
that date, held severally by the Banks in accordance with their Commitment
Percentages. The Term Loan outstanding after conversion shall be evidenced by
the separate Term Notes (the "Term Notes") of the Company payable to the order
of each Bank, each dated as of the Conversion Date and in substantially the form
of Exhibit C attached hereto, with appropriate insertions. On the Conversion
Date the Company shall pay to the Agent for the pro rata accounts of the Banks
all interest accrued to such date on the Revolving Credit Loans, any commitment
fees and other fees payable to the Agent and the Banks hereunder, and, as soon
as reasonably practicable after such payment, each Bank shall surrender to the
Company its Revolving Credit Note against receipt of its Term Note evidencing
the amount of the outstanding Revolving Credit Loans so converted.

                                      -12-

     3.2   THE TERM NOTES.  Each Term Note shall represent the obligation of the
Company to pay to such Bank such principal amount or, if less, the outstanding
amount of such Bank's Commitment Percentage of the Term Loan, plus interest
accrued thereon, as set forth below.  The Company irrevocably authorizes the
Agent to make or cause to be made a notation on the Agent's Term Note Record
reflecting the original principal amount of each Bank's Commitment Percentage of
the Term Loan and, at or about the time of the Agent's receipt of any principal
payment on any Term Note, an appropriate notation on the Term Note Record
reflecting such payment.  The aggregate unpaid amount set forth on each Term
Note Record shall be prima facie evidence of the principal amount thereof owing
and unpaid to each Bank, but the failure to record, or any error in so
recording, any such amount on the Term Note Record shall not affect the
obligations of the Company hereunder or under any Term Note to make payments of
principal of and interest on any Term Note when due.

     3.3   SCHEDULE OF INSTALLMENT PAYMENTS OF PRINCIPAL OF TERM LOAN.  The
Company promises to pay to the Agent for the account of the Banks the principal
amount of the Term Loan in four (4) consecutive quarterly installments, each
equal as near as possible to 1/4th of the principal amount of the Term Loan
outstanding on the Conversion Date, such installments to be due and payable on
the last day of each fiscal quarter of the Company commencing with the fiscal
quarter ending closest to June 30, 1997 with a final payment of all remaining
outstanding principal amounts of the Term Loan, together with all accrued and
unpaid interest thereon, due and payable on the Term Loan Maturity Date.

     3.4   OPTIONAL PREPAYMENT OF TERM LOAN.  The Company shall have the right
at any time to prepay the Term Notes on or before the Term Loan Maturity Date,
as a whole, or in part, upon not less than three (3) Business Days' prior
written notice to the Agent, without premium or penalty, provided that (a) each
partial prepayment shall be in a principal amount equal to $500,000 or an
integral multiple of $100,000 in excess thereof, (b) no portion of the Term Loan
bearing interest at the Eurodollar Rate may be prepaid pursuant to this Section
3.4 except on the last day of the Interest Period relating thereto and (c) each
partial prepayment shall be allocated among the Banks, in proportion, as nearly
as practicable, to the respective outstanding amount of each Bank's Term Note,
with adjustments to the extent practicable to equalize any prior prepayments not
exactly in proportion.  Any prepayment of principal of the Term Loan shall
include all interest accrued to the date of prepayment and shall be applied
against the scheduled installments of principal due on the Term Loan in the
inverse order of maturity.  No amount repaid with respect to the Term Loan may
be reborrowed.

     3.5   INTEREST ON TERM LOAN.

          A.     Except as otherwise provided in Section 4.6, the Term Loan
shall bear interest during each Interest Period relating to all or any portion
of the Term Loan at the following rates:

     (i) To the extent that all or any portion of the Term Loan bears interest
during such Interest Period at the Domestic Rate, the Term Loan or such portion
shall bear interest during such Interest Period at the Domestic Rate plus the
Applicable Margin.

     (ii) To the extent that all or any portion of the Term Loan bears interest
during such Interest Period at the Eurodollar Rate, the Term Loan or such
portion shall bear interest during such Interest Period at the Eurodollar Rate
plus the Applicable Margin.

     (iii)  The Company promises to pay interest on the Term Loan or any portion
thereof outstanding during each Interest Period (a) bearing interest at the
Domestic Rate monthly in arrears on the first day of each month, commencing with
the first such day to occur after the Conversion Date, and on the Term
Loan Maturity Date, on which date all interest remaining unpaid shall be due and
payable; and (b) bearing interest at the Eurodollar Rate at the end of such
Interest Period, provided that if the Interest Period is longer than three
months, then interest shall be due and payable on the date that is three months
from the first day of such Interest Period, and, in addition, on the last day of
such Interest Period.

          B.     The Company shall notify the Agent, such notice to be
irrevocable, at least three (3) Business Days prior to the Conversion Date if
all or any portion of the Term Loan is to bear interest at the Eurodollar Rate.
After the Term Loan has been made, the provisions of Section 2.10 shall apply
mutatis mutandis with respect to all or any portion of the Term Loan so that the
Company may have the same interest rate options with respect to all or any
portion of the Term Loan as it would be entitled to with respect to the
Revolving Credit Loans.

          C.     Any portion of the Term Loan bearing interest at the Eurodollar
Rate relating to any Interest Period shall be in the amount of $500,000 or an
integral multiple of $100,000 in excess thereof.  No Interest Period relating to
the Term Loan or any portion thereof bearing interest at the Eurodollar Rate
shall extend beyond the date on which a regularly scheduled installment payment
of the principal of the Term Loan is to be made unless a portion of the Term
Loan at least equal to such installment payment has an Interest Period ending on
such date or is then bearing interest at the Domestic Rate.

SECTION 4.  CERTAIN GENERAL PROVISIONS

     4.1.  COMPUTATION OF INTEREST AND FEES/ADJUSTMENT TO INTEREST RATES.  All
computations of interest and fees made or called for hereunder shall be
calculated on the basis of a year of 360 days and actual days elapsed.  Any
change in the interest rate applicable to any Domestic Rate Loan resulting from
a change in the Domestic Rate shall become effective as of the day on which such
change in the Domestic Rate shall become effective.

     4.2.  FEES.  The Company shall pay to the Agent (a) for the pro rata
accounts of the Banks on the Closing Date a closing fee in the amount of $25,000
and (b) for the Agent's own account an Agent's fee in the amount and at the
times agreed to by the Agent and the Company.

     4.3   CHANGED CIRCUMSTANCES.

           A.    Notwithstanding any other provision of this Agreement, in the
event any  Bank determines in good faith that:

          (i) the introduction of, any change in, or any change in the
     interpretation or administration of, any law, treaty, directive or
     regulation after the date hereof by any governmental agency charged with
     the interpretation or administration thereof shall make it unlawful or
     impracticable for any Bank to fund or maintain or charge interest with
     respect to any Eurodollar Rate Loan; or

          (ii) by reason of circumstances affecting the Designated Interbank
     Eurodollar Market adequate and reasonable methods do not exist for
     determining the applicable Eurodollar Rate; or

          (iii) deposits of Dollars in the relevant amount for the applicable
     term of a given Eurodollar Rate Loan are not available to such Bank in the
     Designated Interbank Eurodollar Market (any such Loan, an "Affected Loan");

such Bank shall promptly give notice of such determination to the Company. Upon
such date as shall be specified in such notice (which shall not be earlier than
the date such notice is given) the right of the Company to borrow Affected Loans
shall cease to apply and the Company shall, with respect to the outstanding
Affected Loans, convert such Affected Loan to a Domestic Rate Loan. Upon such
specified date the Company shall pay to such Bank the accrued and unpaid
interest on the Affected Loans to (but not including) such specified date. In
addition, the Company hereby agrees promptly to pay the Agent for the accounts
of the Bank upon demand by the Bank, any additional amounts necessary to
compensate such Bank for any costs incurred by such Bank in making any
conversion in accordance with this Section 4.3, including any interest or fees
payable by any Bank to lenders of funds obtained by it in order to make or
maintain its Eurodollar Rate Loans hereunder. If at the time
<PAGE>
 
                                      -14-

any Bank so notifies the Company, the Company has previously given the
Banks a Notice of Borrowing but such Loans have not yet gone into effect, such
notification shall be deemed to be void and the Company may borrow Loans of a
non-affected type by giving an immediate substitute Notice of Borrowing.

          B.     Notwithstanding any other provision of this Agreement, in the
event any Bank determines in good faith that any law, regulation, treaty or
official directive or the interpretation or application thereof by any court or
by any governmental authority charged with the administration thereof or the
compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law)

          (i) subjects any Bank to any tax, levy, impost, duty, charge, fee,
     deduction or withholding of any nature with respect to payments of
     principal or interest or any other amounts payable hereunder by the Company
     or otherwise with respect to the transactions contemplated hereunder
     (except for taxes on the overall net income of such Bank imposed by the
     United States of America or any political subdivision thereof); or
 
          (ii) materially changes the basis of taxation (except for changes in
     taxes on income or profits) of payments to any Bank of the principal of or
     the interest on any Loans or any other amounts payable to any Bank or the
     Agent under this Agreement; or
 
          (iii) imposes, modifies or deems applicable any deposit insurance,
     reserve, special deposit, capital maintenance or similar requirement
     against assets held by, or deposits in or for the account of, or loans by,
     any Bank (other than such requirements as are included in the determination
     of the Eurodollar Rate for Eurodollar Rate Loans, hereunder); or
 
          (iv) imposes upon any Bank or the Agent any other condition or
     requirements with respect to its performance under this Agreement;

and the result of any of the foregoing is to increase the cost to any Bank,
reduce the income receivable by or return on equity of such Bank or impose any
expense upon such Bank with respect to any Loans, such Bank shall notify the
Company thereof.  The Company agrees to pay to each Bank the amount of such
increase in cost, reduction in income or return on equity or additional expense
as and when such cost, reduction or expense is incurred or determined, upon
presentation by such Bank of a statement prepared in good faith in the amount
and setting forth such Bank's calculation thereof, which statement shall be
deemed true and correct absent manifest error.

          C.     Each Bank which is a foreign person (i.e., a person other than
a United States person for United States Federal income tax purposes) (a
"Foreign Bank") agrees that:

          (i) it shall, no later than the Closing Date (or, in the case of a
     Foreign Bank which becomes a party hereto pursuant to Section 13 after the
     Closing Date, the date upon which the Bank becomes a party hereto) deliver
     to the Company through the Agent two accurate and complete signed originals
     of Internal Revenue Service Form 4224 or any successor thereto ("Form
     4224"), or two (2) accurate and complete signed originals of Internal
     Revenue Service Form 1001 or any successor thereto ("Form 1001"), as
     appropriate, in each case indicating that the Foreign Bank is on the
<PAGE>
 
                                      -15-

     date of delivery thereof entitled to receive payments of principal,
     interest and fees under this Agreement free from withholding of United
     States Federal income tax;
 
          (ii) if at any time any Foreign Bank makes any changes necessitating a
     new Form 4224 or Form 1001, it shall with reasonable promptness deliver to
     the Company through the Agent in replacement for, or in addition to, the
     forms previously delivered by it hereunder, two (2) accurate and complete
     signed originals of Form 4224 or two (2) accurate and complete signed
     originals of Form 1001, as appropriate, in each case indicating that the
     Foreign Bank is on the date of delivery thereof entitled to receive
     payments of principal, interest and fees under this Agreement free from
     withholding of United States Federal income tax;
 
          (iii) it shall, before or promptly after the occurrence of any event
     (including the passing of time but excluding any event mentioned in (ii)
     above) requiring a change in or renewal of the most recent Form 4224 or
     Form 1001 previously delivered by such Foreign Bank and deliver to the
     Company through the Agent two (2) accurate and complete original signed
     copies of Form 4224 or Form 1001 in replacement for the forms previously
     delivered by the Foreign Bank; and
 
          (iv) it shall, promptly upon the Company's or the Agent's reasonable
     request to that effect, deliver to the Company or the Agent (as the case
     may be) such other forms or similar documentation as may be required from
     time to time by any applicable law, treaty, rule or regulation in order to
     establish such Foreign Bank's tax status for withholding purposes.
 
          D.     The Company will not be required to pay any additional amounts
in respect of United States Federal income tax pursuant to Section 4.3B to any
Foreign Bank for the account of such Foreign Bank:

          (i) if the obligation to pay such additional amounts would not have
     arisen but for a failure by such Foreign Bank to comply with its
     obligations under Section 4.3C above;
 
          (ii) if such Foreign Bank shall have delivered to the Company a Form
     4224 pursuant to Section 4.3C, and such Foreign Bank shall not at any time
     be entitled to exemption from deduction or withholding of United States
     Federal income tax in respect of payments by the Company hereunder for the
     account of such Foreign Bank for any reason other than a change in United
     States law or regulations or in the official interpretation of such law or
     regulations by any governmental authority charged with the interpretation
     or administration thereof (whether or not having the force of law) after
     the date of delivery of such Form 4224; or
 
          (iii) if the Foreign Bank shall have delivered to the Company a Form
     1001 in respect of such Foreign Bank pursuant to Section 4.3C, and such
     Foreign Bank shall not at any time be entitled to exemption from deduction
     or withholding of United States Federal income tax in respect of payments
     by the Company hereunder for the account of such Foreign Bank for any
     reason other than a change in United States law or regulations or any
     applicable tax treaty or regulations or in the official interpretation of
     any such law, treaty or regulations by any governmental authority charged
     with the interpretation or administration thereof (whether or not having
     the force of law) after the date of delivery of such Form 1001 .

          E.     Notwithstanding any other provision of this Agreement, in the
event that any Bank determines in good faith that the adoption of or any change
in any applicable law, rule or regulation regarding capital requirements for
banks or bank holding companies, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by such Bank or the Agent with any request or directive of any such entity
regarding capital adequacy (whether or not having the force of law), has the
effect of reducing the return on such Bank's capital to a level below that which
such Bank could have achieved (taking into consideration such Bank's policies
with respect to capital adequacy immediately before such adoption, change or
compliance and assuming that such Bank's capital was fully utilized prior to
such adoption, change or compliance) but for such adoption, change or compliance
as a consequence of its commitment to make Loans hereunder by any amount deemed
by such Bank to be material:

          (i) such Bank shall promptly after its determination of such
     occurrence give notice thereof to the Company; and
 
          (ii) the Company shall pay to such Bank as an additional fee from time
     to time on demand such amount as such Bank certifies to be the amount that
     will compensate it for such reduction; provided that the Company shall have
     no obligation with respect to periods more than three months prior to any
     such notice.
 
A certificate of any Bank claiming compensation under this Section 4.3 shall be
conclusive in the absence of manifest error.  Such certificate shall set forth
the nature of the occurrence giving rise to such compensation, the additional
amount or amounts to be paid to it hereunder and the method by which such
amounts were determined.  In determining such amount, the Banks may use any
reasonable averaging and attribution methods.
<PAGE>
 
                                      -16-

     4.4   PAYMENTS FREE OF TAXES.  All payments made by the Company in
connection with this Agreement shall be made free and clear of, and without
reduction by reason of, any taxes.

     4.5   FUNDING SOURCES.  Other than as specifically stated herein, nothing
herein shall be deemed to obligate any Bank to fund any Loan hereunder in any
particular place or manner and nothing herein shall be deemed to constitute a
representation by any Bank that it has funded or will fund any Loan hereunder in
any particular place or manner.

     4.6   LATE PRINCIPAL AND INTEREST.  Should principal and/or interest not be
paid when due (after all applicable grace periods set forth in this Agreement,
if any, have elapsed) with respect to any Loan made hereunder, it shall
thereafter bear interest at a fluctuating rate per annum equal to 2% in excess
of the interest rate in effect on such Loan.
<PAGE>
 
                                      -17-

     4.7   PLACE OF LOANS AND PAYMENTS.  All Loans made hereunder and other
amounts payable hereunder shall be paid to the Agent at the office of the Agent
in Boston, Massachusetts for the account of each Bank.  Payments made by the
Company under this Agreement shall be received by the Agent no later than 1:00
p.m., Boston, Massachusetts time on the date that the payment is due.  Each Bank
agrees to timely provide a statement of all amounts due and payable hereunder
from time to time, provided that the failure to provide such a notice shall not
affect the unconditional obligation of the Company to pay such amounts on the
dates herein provided.

     4.8   IMMEDIATELY AVAILABLE DOLLARS.  All Loans and payments hereunder
shall be made in Dollars and in immediately available funds.

     4.9  FAILURE TO CHARGE NOT SUBSEQUENT WAIVER.  The Company explicitly
agrees that any decision by the Agent or any Bank not to require payment of any
fees and/or compensation for costs, or to reduce that amount of such fees and/or
compensation for costs, for any particular Eurodollar Rate Loan shall in no way
limit the Agent's or such Bank's right to require full payment of any fees
and/or compensation for costs for any other Eurodollar Rate Loan.

     4.10 IDENTIFICATION OF DESIGNATED INTERBANK EURODOLLAR MARKET.  Upon
request of the Company communicated to the Agent, the Agent shall identify the
interbank Eurodollar market that constitutes the Designated Interbank Eurodollar
Market for any Eurodollar Rate Loan.

     4.11 PRO RATA LOANS; OBLIGATIONS SEVERAL.

          A. The Company, the Agent and the Banks agree that each extension of
credit shall be made on a pro rata basis by the Banks in accordance with their
respective Commitment Percentages. Each payment and prepayment of Loans, and
each payment of interest and fees, made by the Company to the Agent shall be
made, and each reduction of the Commitment shall be applied, pro rata to the
Banks in proportion to the respective amounts of the Loans outstanding
immediately prior to such payment or prepayment or, if no Loans are outstanding,
in the proportion that each Bank's Commitment bears to the Total Commitment.

          B. The obligations of each Bank under this Agreement are several. The
failure of any Bank to meet its obligations hereunder shall not release any
other Bank from its obligations as provided herein. No Bank shall be liable for
the failure of any other Bank to perform its obligations under this Agreement.

     4.12 SURVIVABILITY.  Except as otherwise specified herein, all of the
Company's obligations under Section 2 and 3 hereof with respect to any Loans
made hereunder shall survive repayment of such Loans.

     4.13 INDEMNITY.  The Company agrees to indemnify each Bank and to hold each
Bank harmless from and against any loss, cost or expense that such Bank may
sustain or incur as a consequence of (a) default by the Company in payment of
the principal amount of or any interest on any Eurodollar Rate Loans as and when
due and payable, including any such loss or expense arising from interest or
fees payable by such Bank to lenders of funds obtained by it in order to
maintain its Eurodollar Rate Loans, (b) default by the Company in making a
borrowing after the Company has given (or is deemed to have given) a loan
request, notice (in the case of all or any portion of the Term Loan pursuant to
Section 3.5) or a Conversion Request relating thereto in accordance with Section
2.10 or Section 3.5 or (c) the making of any payment of a Eurodollar Rate Loan
or the making of any conversion of any such Loan to a Domestic Rate Loan on a
day that is not the last day of the applicable Interest Period with respect
thereto, including interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain any such Loans.

             SECTION 6.  COMPANY'S REPRESENTATIONS AND WARRANTIES

     To induce the Agent and the Banks to enter into this Agreement and make the
Loans, the Company makes the following representations and warranties to each of
the Banks:

     6.1 EXISTENCE AND RIGHTS. The Company and its Subsidiaries are corporations

Banks, the Company has no investment in any other corporation other than its
Subsidiaries listed in Exhibit B annexed hereto.

Agreement and the Loan Documents are duly authorized by all necessary corporate

                                      -20-

     6.3  NO CONFLICT.  The execution, delivery and performance of this
Agreement and the Loan Documents will not breach or constitute a default under
any agreement, indenture, undertaking or other instrument to which the Company
or its Subsidiaries are a party or by which they or any of their property may be
bound or affected, and such execution, delivery and performance will not result
in the creation or imposition of (or the obligation to create or impose) any
lien, charge or encumbrance on, or security interest in, any of their property
pursuant to the provisions of any of the foregoing.

     6.4  LITIGATION.  Except as shall have been disclosed in the Disclosure
Letter to the Agent and the Banks, there is no litigation or other proceedings
pending or, to the knowledge of the Company, affecting it or its Subsidiaries or
their properties that, if determined adversely to the Company or its
Subsidiaries, would have a materially adverse effect on the financial condition,
properties or operations of the Company or the Company and its Subsidiaries,
taken as a whole, and neither the Company nor any of its Subsidiaries is in
default with respect to any order, writ, injunction, decree or demand of any
court or other governmental or regulatory authority where such default would
have a material adverse effect on the financial condition, properties or
operations of the Company or the Company and its Subsidiaries, taken as a whole.

     6.5  FINANCIAL CONDITION.  The consolidated balance sheet of the Company
and its Subsidiaries as of December 31, 1994, and the related statements of
profit and loss, cash flow and changes in stockholders' equity for the twelve
months ended on that date, all as certified by public accountants acceptable to
the Banks, a copy of each of which has heretofore been delivered to the  Banks
by the Company, and all other statements and data submitted in writing in
connection with the request for the credit granted by this Agreement, are true
and correct in all material respects, and said balance sheets, profit and loss
statements and other statements and data fairly present the financial condition
of the Company and its Subsidiaries as of the dates thereof and the results of
the operations of the Company and its Subsidiaries for the periods covered
thereby, and have been prepared in accordance with generally accepted accounting
principles on a basis consistently maintained.  Since said dates there have been
no changes in the assets, liabilities or financial condition of the Company or

appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
(or similar official) for the Company or any of its Subsidiaries or for any
substantial part of its property, or ordering the winding up or liquidation of
its affairs and said case shall not be dismissed within 30 days, provided,
however, that should the Company or any of its Subsidiaries consent to the
commencement of the involuntary case, the thirty-day period shall be deemed to
have run; or the Company or any of its Subsidiaries shall commence a voluntary
case under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or shall consent to the entry of an order for relief in an
involuntary case under any such law, or shall consent to the appointment of or
taking possession by a receiver, liquidator, assignee, trustee, custodian,

become due or shall take any corporate action in furtherance of any of the
foregoing;

          F.  any money judgment in excess of $3,000,000 that is not covered by

jurisdiction, where such noncompliance has an adverse material effect on the
Company or any Subsidiary or any of its assets; or

          H.  the Company or any member of the "controlled group" (as such term

trustee to be appointed to administer any such Plan or Plans or a proceeding

and such proceedings shall not have been dismissed within 30 days thereafter; or
a condition shall exist by reason of which the PBGC would be entitled to obtain
a decree adjudicating that any such Plan or Plans must be terminated;
then, and in any such event, so long as the same may be continuing, the Agent
may, and upon the request of the Required Banks shall, by notice in writing to
the Company, declare all amounts owing with respect to this Agreement and the
Notes to be, and they shall thereupon forthwith become, immediately due and
payable, without presentment, demand, protest or other notice of any kind, all

          10.2  TERMINATION OF COMMITMENTS.  If any one or more of the Events of
Default specified in Section 10.1E shall occur, any unused portion of the credit
hereunder shall forthwith terminate and each of the Banks shall be relieved of
all obligations to make Loans to the Company.  If any other Event of Default
shall have occurred and be continuing, the Agent may and, upon the request of
the Required Banks, shall, by notice to the Company, terminate the unused
portion of the credit hereunder, and upon such notice being given such unused
portion of the credit hereunder shall terminate immediately and each of the
Banks shall be relieved of all further obligations to make Loans.  If any such
notice is given to the Company the Agent will forthwith furnish a copy
thereof to each of the Banks.  No termination of the credit hereunder shall
relieve the Company of any of the obligations or any of its existing obligations
to any of the Banks arising under other agreements or instruments.

          10.3  REMEDIES.  In case any one or more of the Events of Default
shall have occurred and be continuing, and whether or not the Banks shall have
accelerated the maturity of the Loans pursuant to Section 10.1, each Bank, if
owed any amount with respect to the Loans, may, with the consent of the Required
Banks but not otherwise, proceed to protect and enforce its rights by suit in
equity, action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Agreement or any
instrument pursuant to which the obligations to such Bank are evidenced,
including as permitted by applicable law the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Bank.  No remedy herein conferred upon any Bank
or the Agent or the holder of any Note is intended to be exclusive of any other
remedy and each and every remedy shall be cumulative and shall be in addition to
every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or any other provision of law.

                            SECTION 11.  THE AGENT

      11.1  AUTHORIZATION.

          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 under any of the
other Loan Documents and any related documents delegated to the Agent, together
with such powers as are reasonably incident thereto, provided that no duties or
responsibilities not expressly assumed herein or therein shall be implied to
have been assumed by the Agent.

          B.  The relationship between the Agent and each of the Banks is that
of an independent contractor.  The use of the term "Agent" is for convenience
only and is used to describe, as a form of convention, the independent
contractual relationship between the Agent and each of the Banks.  Nothing
contained in this Credit Agreement nor the other Loan Documents shall be
construed to create an agency, trust or other fiduciary relationship between the
Agent and any of the Banks.

          C.  As an independent contractor empowered by the Banks to exercise
certain rights and perform certain duties and responsibilities hereunder and
under the other Loan Documents, the Agent is nevertheless a "representative" of
the Banks, as that term is defined in Article 1 of the Uniform Commercial Code,
for purposes of actions for the benefit of the Banks and the Agent with respect
to all collateral security and guaranties contemplated by the Loan Documents.
Such actions include the designation of the Agent as "secured party",
"mortgagee" or the like on all financing statements and other documents and
instruments, whether recorded or otherwise, relating to the attachment,
perfection, priority or enforcement of any security interests, mortgages or
deeds of trust in collateral security intended to secure the payment or
performance of any of the Obligations, all for the benefit of the Banks and the
Agent.

      11.2  EMPLOYEES AND AGENTS.

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 other Loan Documents.  The Agent may utilize the services of such
Persons as the Agent in its sole discretion may reasonably determine.

      11.3  NO LIABILITY.

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 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
any of the other Loan Documents, or in connection herewith or therewith, or be
responsible 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.
 
<PAGE>
 
                                      -31-

      11.4  NO REPRESENTATIONS.

The Agent shall not be responsible for the execution or validity or
enforceability of this Agreement, the Notes, any of the other Loan Documents or
any instrument at anytime constituting, or intended to constitute, collateral
security for the Notes, or for the value of any such collateral security or for
the validity, enforceability or collectability of any such amounts owing with
respect to the Notes, or for any recitals or statements, warranties or
representations made herein or in any of the other Loan Documents or in any
certificate or instrument hereafter furnished to it by or on behalf of the
Company, 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 the Notes or to inspect any of the properties, books or records of
the Company or any of its Subsidiaries.  The Agent shall not be bound to
ascertain whether any notice, consent, waiver or request delivered to it by the
Company 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 credit worthiness or financial
conditions of the Company or any of its Subsidiaries.  Each Bank acknowledges
that it has, independently and without reliance upon the Agent or any other
Bank, and based upon such information and documents as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.

      11.5  PAYMENTS.

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

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

          C.  Notwithstanding anything to the contrary contained in this
Agreement or any of the other Loan Documents, any Bank that fails (i) to make
available to the Agent its pro rata share of any Loan or (ii) to comply with the
provisions of Section 14.12 with respect to making dispositions and arrangements
with the other Banks, where such Bank's share of any payment received, whether
by setoff or otherwise, is in excess of its pro rata share of such payments due
and payable to all of the Banks, in each case as, when and to the full extent
required by the provisions of this Agreement, shall be deemed delinquent (a
"Delinquent Bank") and shall be deemed a Delinquent Bank until such time as such
delinquency is satisfied.  A Delinquent Bank shall be deemed to have assigned
any and all payments due to it from the Company, whether on account of
outstanding Loans, interest, fees or otherwise, to the remaining nondelinquent
Banks for application to, and reduction of, their respective pro rata shares of
all outstanding Loans.  The Delinquent Bank hereby authorizes the Agent to
distribute such payments to the nondelinquent Banks in proportion to their
respective pro rata shares of all outstanding Loans.  A Delinquent Bank shall be
deemed to have satisfied in full a delinquency when and if, as a result of
application of the assigned payments to all outstanding Loans of the
nondelinquent Banks, the Banks' respective pro rata shares of all outstanding
Loans have returned to those in effect immediately prior to such delinquency and
without giving effect to the nonpayment causing such delinquency.

                                      -32-

          11.6  HOLDERS OF NOTES.  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.

          11.7  INDEMNITY.  The Banks ratably agree hereby to indemnify and hold
harmless the Agent from and against any and all claims, actions and suits
(whether groundless or otherwise), losses, damages, costs, expenses
(including any expenses for which the Agent has not been reimbursed by the
Company as required by Section 8.8), and liabilities of every nature and
character arising out of or related to this Agreement, the Notes, or any of the
other Loan Documents or the transactions contemplated or evidenced hereby or
thereby, or the Agent's actions taken hereunder or thereunder, except to the
extent that any of the same shall be directly caused by the Agent's willful
misconduct or gross negligence.

          11.8  AGENT AS BANK.  In its individual capacity, FNBB shall have the
same obligations and the same rights, powers and privileges in respect to its
Commitment and the Loans made by it, and as the holder of any of the Notes, as
it would have were it not also the Agent.

          11.9  RESIGNATION.  The Agent may resign at any time by giving thirty
(30) days prior written notice thereof to the Banks and the Company.  Upon any
such resignation, the Required Banks shall have the right to appoint a successor
Agent.  Unless a Default or Event of Default shall have occurred and be
continuing, such successor Agent shall be reasonably acceptable to the Company.
If no successor Agent shall have been so appointed by the Required Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be a financial institution
having a rating of not less than A or its equivalent by Standard & Poor's
Corporation.  Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder.  After any retiring Agent's resignation, the provisions of this
Agreement and the other Loan Documents shall continue in effect for its benefit
in respect of any actions taken or omitted to be taken by it while it was acting
as Agent.

                   SECTION 12.  SURVIVAL OF COVENANTS, ETC.

          All covenants, agreements, representations and warranties made herein,
in the Notes, in any of the other Loan Documents or in any documents or other
papers delivered by or on behalf of the Company or any of its Subsidiaries
pursuant hereto shall be deemed to have been relied upon by the Banks and the
Agent, notwithstanding any investigation heretofore or hereafter made by any of
them, and shall survive the making by the Banks of the Loans, as herein
contemplated, and shall continue in full force and effect so long as any amount
due under this Agreement or the Notes or any of the other Loan Documents remains
outstanding or any Bank has any obligation to make any Loans, and for such
further time as may be otherwise expressly specified in this Agreement.  All
statements contained in any certificate or other paper delivered to any Bank or
the Agent at any time by or on behalf of the Company or any of its Subsidiaries
pursuant hereto or in connection with the transactions contemplated hereby shall
constitute representations and warranties by the Company or such Subsidiary
hereunder.

                   SECTION 13.  ASSIGNMENT AND PARTICIPATION

          13.1 CONDITIONS TO ASSIGNMENT BY BANKS. Except as provided herein,
each Bank may assign to one or more Eligible Assignees all or a portion of its
interests, rights and obligations under this Agreement (including all or a
portion of its Commitment Percentage and Commitment and the same portion of the
Loans at the time owing to it) and the Notes held by it; provided that (a) each
of the Agent and the Company shall have given its prior written consent to such

withheld, (b) each such assignment shall be of a constant, and not a varying,

Agreement, (c) each assignment shall be in a minimum amount of $5,000,000 and an

(e) the parties to such assignment shall execute and deliver to the Agent, for

Acceptance, substantially in the form of Exhibit F hereto (an "Assignment and
Acceptance"), together with any Notes 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, (x) 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,

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;

          C.  such assignee confirms that it has received a copy of this
Agreement, together with copies of the most recent financial statements referred

such Assignment and Acceptance;

          D.  such assignee will, independently and without reliance upon the

                                      -34-

          13.3  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 Revolving Credit 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 such recordation, the assigning Bank agrees
to pay to the Agent a registration fee in the sum of $2,500.

          13.4  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, the Company, at its own expense, shall execute and 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 and, if the assigning Bank
has retained some portion of its obligations hereunder, a new Note to the order
of the assigning Bank in an amount equal to the amount retained by it hereunder.
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 Assignment and Acceptance and shall otherwise be in substantially the form
of the assigned Notes. Within five (5) Business Days of issuance of any new
Notes pursuant to this Section 13.4, the Company shall deliver an opinion of
counsel, addressed to the Banks and the Agent, relating to the due
authorization, execution and delivery of such new Notes and the legality,
validity and binding effect thereof, in form and substance satisfactory to the
Banks. The surrendered Notes shall be cancelled and returned to the Company.

          13.5  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, (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.

          13.6  ASSIGNEE OR PARTICIPANT AFFILIATED WITH THE COMPANY.  If any
assignee Bank is an Affiliate of the Company, then any such assignee 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 other modifications to any of the Loan Documents or
for purposes of making requests to the Agent pursuant to Section 10, and the
determination of the Required 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 10 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.

          13.7  MISCELLANEOUS ASSIGNMENT PROVISIONS.  Any assigning Bank shall
retain its rights to be indemnified pursuant to Section 8.9 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.  If any
Reference Bank transfers all of its interest, rights and obligations under this
Agreement, the Agent shall, in consultation with the Company and with the
consent of the Company and the Required Banks, appoint another Bank to act as a
Reference Bank hereunder.  Anything contained in this Section 13 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 Section 4 of
the Federal Reserve Act, 12 U.S.C. Section 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.


          13.8  ASSIGNMENT BY COMPANY.  The Company shall not 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.

                          SECTION 14.  MISCELLANEOUS

          14.1  SURVIVAL OF WARRANTIES.  All agreements, representations and
warranties made herein shall survive the execution and delivery of this
Agreement and the making of the Loans hereunder.

          14.2  FAILURE OR INDULGENCE NOT WAIVER.  No failure or delay on the
part of the Banks in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power, right or privilege preclude other or further exercise thereof or
of any other power, right or privilege.  All rights and remedies existing under
this Agreement are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

          14.3  MODIFICATION.  Neither this Agreement nor any provision hereof
or thereof may be amended, waived, discharged or terminated except by a written
instrument amending, waiving, discharging or terminating such provision, as the
case may be, signed by the Required Banks and, in the case of amendments, by the
Company; provided that any amendment or waiver that changes (a) any required
payment date, (b) any of the rates of interest that may be charged on the Loans,
(c) any fees payable to any Bank (which for purposes of this Section 14.3 only
shall not include fees payable to the Agent), (d) the Commitments of any Bank,
(e) the rate of amortization of any Loan, (f) the definitions of "Required
Banks", or (g) the release of any guarantor or any substantial amount of any
collateral for the Loans, shall require a written instrument signed by all the
Banks, and provided, further, that any amendment to Section 11 or that otherwise
purports to affect the rights and liabilities of the Agent hereunder shall also
be signed by the Agent.

          14.4  NOTICES.  Except as otherwise expressly provided herein, any
notice herein required or permitted to be given shall be in writing and may be
personally served or sent by United States mail, and shall be deemed to have
been given when deposited in the United States mail, registered, with postage
prepaid, or sent by telex, answerback received, or electronic facsimile
transmission, receipt acknowledged, or delivered to an overnight courier, in
each case properly addressed.  For the purposes hereof, the addresses of the

Commonwealth of Massachusetts.  The Banks retain all of their rights under
federal law, including those relating to the charging of interest rates.

          14.7 COUNTERPARTS.  This Agreement may be executed in two or more

          14.12 SHARING OF SETOFFS. Regardless of the adequacy of any
collateral, during the continuance of any Event of Default, any deposits or
other sums credited by or due from any of the Banks to the Company and any
securities or other properties of the Company in possession of such Bank may be
applied to or set off by such Bank against the payment of obligations of the
Company and any and all other liabilities, direct or indirect, absolute or
contingent, due or to become due, now existing or hereafter arising, of the
Company to such Bank. Unless otherwise expressly provided herein, all interest,
fees and principal payments on the Loans to the Company hereunder are to be
divided among the Banks in the same proportion as each Bank's Commitment
Percentage. Any sums obtained from the Company or any Subsidiary by any Bank by

shall be shared among all the Banks in the same proportion and applied first to
indebtedness of the Company under this Agreement. Nothing in this Section shall
be deemed to require the sharing among the Banks of collections (other than by
setoff or banker's lien) with respect to any other indebtedness of the Company
or any Subsidiary to any Bank.
