              Notes to Condensed Consolidated Financial Statements
                                  June 30, 1997
                                   (Unaudited)


1.  BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
         have been prepared in accordance with generally accepted accounting
         principles for interim financial information and pursuant to the rules
         and regulations of the Securities and Exchange Commission. Accordingly,
         they do not include all of the information and footnotes required by
         generally accepted accounting principles for complete financial
         statements.

         In the opinion of management, all adjustments (consisting of only
         normal recurring adjustments) considered necessary for a fair
         presentation have been included. Operating results for the three- and
         six-month periods ended June 30, 1997 are not necessarily indicative
         of the results that may be expected for the year ended December 31,
         1997. For further information, refer to the consolidated financial
         statements and notes thereto included in the Company's audited
         financial statements for the year ended December 31, 1996, contained in
         the Company's annual report filed on Form 10-K (File #0-18277) with the
         Securities and Exchange Commission.

2.  NET INCOME PER SHARE

         Net income per common share is based on the weighted average number of
         shares of common shares and common share equivalents.

         In February 1997, the Financial Accounting Standards Board issued
         Statement No. 128, "Earnings per Share," which is effective for the
         Company on December 31, 1997. At that time, the Company will be
         required to change the method currently used to compute earnings per
         share and to restate all prior periods. Under the new requirements for
         calculating primary earnings per share, the dilutive effect of stock
         options will be excluded. There is not expected to be any material
         change to either primary or fully diluted net income per share for the
         quarters or the six months ended June 30, 1997 and 1996 as a result of
         the new method.


3.  INVENTORIES

         Inventories are valued at the lower of cost (determined using the
         first-in, first-out method) or market. Costs associated with the
         long-term contract for the sale of automated manufacturing line
         equipment are included in inventories reduced by amounts identified
         with revenues recognized under the contract. Inventories were as
         follows as of June 30, 1997 and December 31, 1996 (in thousands):

              Notes to Condensed Consolidated Financial Statements

                                   (Continued)


4.  MORTGAGE NOTE RECEIVABLE

         In May 1997, the Company received a promissory note in the amount of
         $7,500,000 from an unrelated third party in exchange for $5,000,000 in
         cash plus the termination of an existing note in the amount of
         $2,500,000. The note bears interest at 9% and is due in May 2002. The
         note is secured by a mortgage on certain real estate and by the
         assignment of certain leases and other contracts.

5.  IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         In June 1997, the FASB issued Statement No. 130, "Reporting
         Comprehensive Income," and Statement No. 131, "Disclosures About
         Segments of an Enterprise and Related Information." Statement No. 130
         establishes standards for the reporting and display of comprehensive
         income and its components. Statement No. 131 establishes standards for
         the way that public companies report information about operating
         segments in financial statements. This Statement supersedes Statement
         No. 14, "Financial Reporting for Segments of a Business Enterprise,"
         but retains the requirements to report information about major
         customers. Statements 130 and 131 are effective for the Company in
         fiscal 1998. The Company does not believe that the adoption of these
         Statements will have a material effect on the Company's financial
         statements.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations
                                  June 30, 1997


Except for historical information contained herein, some matters discussed in
this report constitute forward-looking statements within the meaning of Section
27A of the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. Actual results could differ materially from
those projected in the forward-looking statements as a result of the risk
factors set forth in this report and in the Company's Annual Report on Form 10-K
for the year ended December 31, 1996. Reference is made in particular to the
discussions set forth below in this Report under "Management's Discussion and
Analysis of Financial Condition and Results of Operations," and set forth in the
Annual Report on Form 10-K under Item 1 -- "Business -- Next-Generation
Automated Manufacturing Line," "--Competition," "--Patents," and "--Licensing,"
and under Item 7 -- "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

Results of Operations
- ---------------------

Three months ended June 30, 1997, compared to three months ended June 30, 1996
- ------------------------------------------------------------------------------

Net revenues for the second quarter of 1997 were $39,718,000, an increase of
$3,016,000 (8.2%) as compared to $36,702,000 for the same period a year ago. The
increase in net revenues was primarily due to an increase of unit shipments of
standard and custom products of approximately $4,400,000, offset by a reduction
in license income of approximately $1,100,000.

Gross margin increased $569,000 (2.9%) to $20,416,000 from $19,847,000, but
decreased as a percentage of net revenues from 54.1% to 51.4%. The primary
components of the increase in gross margin were changes in the revenue mix.

Selling, general and administrative expenses were $7,483,000 for the period, an
increase of $711,000 (10.5%) over the same period in 1996. As a percentage of
net revenues, selling, general and administrative expenses increased to 18.8%
compared to 18.5% in 1996. The principal components of the $711,000 increase
were $470,000 (19.3%) of increased compensation expense due to growth in
staffing levels of selling and administrative personnel; $142,000 (125.1%) of
increased legal expenses; $84,000 (10.0%) of increased advertising expenses; and
$84,000 (8.0%) of increased sales commission expense.

Research and development expenses increased $915,000 (27.7%) to $4,221,000 and
increased as a percentage of net revenues to 10.6% from 9.0%. The principal
components of the $915,000 increase were $484,000 (25.0%) of increased
compensation expense due to growth in staffing levels of engineering personnel
and $148,000 (30.7%) of increased project material costs. The Company continues
work on its next-generation products. The Company does not expect revenues or
earnings from this new product family to be material over the next several
quarters. See also the discussion under "Liquidity and Capital Resources."

Other income increased $337,000 (37.7%) from the same period a year ago, to
$1,230,000. Other income is primarily comprised of interest income derived from
cash and cash equivalents, short-term investments, and notes receivable
associated with the Company's real estate transactions in Andover,
Massachusetts. Interest income increased primarily due to an increase in cash
balances earning interest.

Income before income taxes was $9,942,000, a decrease of $720,000 (6.8%)
compared to the same period in 1996. As a percentage of net revenues, income
before income taxes decreased from 29.1% to 25.0% primarily due to the increase
in operating expenses as discussed above.

Net income per share for the second quarter of 1997 was $.15, compared to $.16
for the second quarter of 1996, a decrease of $.01 (6.3%).

Six months ended June 30, 1997, compared to six months ended June 30, 1996
- --------------------------------------------------------------------------

Net revenues for the first six months of 1997 were $77,657,000, an increase of
$5,149,000 (7.1%) as compared to $72,508,000 for the same period a year ago. The
increase in net revenues was primarily due to an increase of unit shipments of
standard and custom products of approximately $5,800,000, offset by a reduction
in license income of approximately $1,100,000.

Gross margin increased $1,372,000 (3.5%) to $40,478,000 from $39,106,000, but
decreased as a percentage of net revenues from 53.9% to 52.1%. The primary
components of the increase in gross margin were changes in the revenue mix.

Selling, general and administrative expenses were $14,930,000 for the period, an
increase of $1,923,000 (14.8%) over the same period in 1996. As a percentage of
net revenues, selling, general and administrative expenses increased to 19.2%
compared to 17.9% in 1996. The principal components of the $1,923,000 increase
were $1,064,000 (22.8%) of compensation expense due to growth in staffing levels
of selling and administrative personnel; $401,000 (27.0%) of increased
advertising expenses; $184,000 (48.6%) of increased legal expenses; and $139,000
(6.8%) of increased sales commission expense.

Research and development expenses increased $1,852,000 (27.4%) to $8,600,000 and
increased as a percentage of net revenues to 11.1% from 9.3%. The principal
components of the $1,852,000 increase were $1,036,000 (27.2%) of compensation
expense due to growth in staffing levels of engineering personnel and $264,000
(22.7%) of increased project material costs.

Other income increased $449,000 (23.8%) to $2,332,000. Other income is primarily
comprised of interest income derived from cash and cash equivalents, short-term
investments, and notes receivable associated with the Company's real estate
transactions in Andover, Massachusetts. Interest income increased primarily due
to an increase in cash balances earning interest.

Income before income taxes was $19,280,000, a decrease of $1,954,000 (9.2%)
compared to the same period in 1996. As a percentage of net revenues, income
before income taxes decreased from 29.3% to 24.8% primarily due to the increase
in operating expenses as discussed above.

Net income per share for the first six months of 1997 was $.29, compared to $.32
for the first six months of 1996, a decrease of $.03 (9.4%).

Liquidity and Capital Resources
- -------------------------------

At June 30, 1997 the Company had $80,843,000 in cash and cash equivalents. The
ratio of current assets to current liabilities was 8.2:1 compared to 8.8:1 at
December 31, 1996. Working capital increased $8,898,000, from $108,551,000 at
December 31, 1996 to $117,449,000 at June 30, 1997. The primary factor affecting
the working capital increase was an increase in cash of $7,196,000 during the
first six months of 1997. The increase in cash was primarily attributable to
cash derived from operating activities of $14,882,000; the net proceeds from the
issuance of Common Stock upon the exercise of stock options, and the related
income tax benefit derived from such issuance, of $6,308,000. The primary uses
of cash for the first six months of 1997 were for additions to property and
equipment of $8,406,000 and for increased notes receivable of $5,215,000. See
the discussion under "Notes to Condensed Consolidated Financial Statements,"
Item 4--"Mortgage Note Receivable."

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations
                                  June 30, 1997
                                   (continued)

The Company plans to make continuing investments in manufacturing equipment,
much of which is built internally. The internal construction of manufacturing
machinery is a practice which the Company expects to follow over the next
several years.

In 1995, the Company announced that it had started prototype production on a new
automated manufacturing line specifically designed to manufacture
next-generation products. In the fourth quarter of 1996, the Company began
introducing selected models of its next-generation product families. While
management believes that the initiation of limited production on the new
manufacturing line and the introduction of selected models of its
next-generation product families are important milestones, there can be no
assurance that problems will not substantially delay the ultimate general
introduction of the complete product line, require modification of product
specifications, or prevent attainment of the anticipated capacity of the new
manufacturing line. Significant revenues from the sale of any products in the
Company's next-generation product line are not expected to occur for several
quarters.

In February, 1996, the Board of Directors of the Company authorized the
repurchase of the Company's Common Stock up to an aggregate amount of
approximately $19,500,000, including amounts remaining under a prior
authorization. The plan authorized the Company to make such repurchases from
time to time in the open market or through privately negotiated transactions.
The timing of this program and the amount of the stock that may be repurchased
is at the discretion of management based on its view of economic and financial
market conditions. There were no repurchases in the six months ended June 30,
1997.

The Company has an unused line of credit with a bank under which the Company may
borrow up to $4,000,000 on a revolving credit basis. The Company believes that
cash generated from operations and the total of its cash and cash equivalents,
together with other sources of liquidity, will be sufficient to fund planned
operations and capital equipment purchases for the foreseeable future. At June
30, 1997, the Company had approximately $700,000 of capital expenditure
commitments.

The Company does not consider the impact of inflation on its business activities
to have been significant to date.

- --------------------------
