                                     PART I
                                ITEM 1. BUSINESS

THE COMPANY

Founded in 1946, Instron Corporation ("Instron" or the "Company") designs,
develops, manufactures, markets, and services materials and structural testing
systems, software, and accessories. These products are used principally in
research and development and quality control applications to test the mechanical
properties of various materials, components, and structures. The materials
tested include metals, plastics, textiles, composites, ceramics and rubber.
Instron systems test virtually all natural and man-made materials from fragile
fibers to the exotic materials needed for space exploration.

In the worldwide market for these systems, Instron is a leading producer of
static (electromechanical), dynamic (servohydraulic), simulation (structures),
hardness and impact testing systems. Instron offers a comprehensive range of
instruments and computer based systems that provide and enhance control of the
testing process, data collection and analysis.

Instron's products are typically assembled from a number of company-designed
standard hardware and software modules and accessories, selected and configured
for the customer's specific application. Additional hardware, software and
accessories may be added to the system at a later date.

The Company has sales and service offices in 14 United States cities and 17
foreign countries. Approximately 55% of the Company's revenues are derived from
sales outside the United States. Principal manufacturing facilities are located
in the United States, the United Kingdom and Germany.

PRINCIPAL MARKETS

The Company's principal markets are industrial and academic institutions and
governments; organizations that seek to understand the characterization and
properties of materials and products.

INDUSTRY - Most major industries use materials testing systems as a part of
their research and development and quality control activities. Industrial
research focuses upon developing new materials, substitute materials, or new
uses for existing materials that reduce manufacturing or operating costs and
improve product quality and durability. Industrial activity and structural
testing tends to be concentrated in the automotive, transportation, aerospace
and civil engineering sectors.

Industrial quality control involves testing the properties of finished products
as well as materials used as inputs to the manufacturing process.

                                       2
<PAGE>   3


ACADEMIC INSTITUTIONS - Academic institutions use Instron products for
both basic research and instruction in materials science. The Company places
particular emphasis on academic institutions because scientists and engineers
trained on Instron equipment may influence additional sales of the Company's
products later in their careers.

GOVERNMENTS - Government and government agency use of Instron products
principally involves testing which supports defense, space, and civil
engineering programs, ascertains compliance with safety and other legal
requirements, and conducts research on new materials and emerging
technologies.

PRINCIPAL PRODUCTS

Instron offers a comprehensive range of general-purpose materials testing
systems, application software, and accessories within two principal product
lines; static systems and dynamic systems. The major distinction between a
static system and a dynamic system is the means used to apply force to the test
specimen. The former uses a screw-driven moving crosshead and the latter a
servo-controlled hydraulic actuator. Many tests can be carried out equally well
with either a static or dynamic test machine. However, if the test requires
extremely rapid rates of loading, or subjects the test material to rapidly
fluctuating loads, then a dynamic test machine is appropriate. Instron's product
offerings vary in the force capacity of the machines, the complexity of the
drive system, and the sophistication of the control electronics, the computer
system, and the software.

STATIC SYSTEMS - Static (electromechanical) systems consist of a frame, a moving
crosshead, a load cell, grips, and electronic modules to control the test and
analyze the test data. Static systems typically stretch or compress the material
being tested at a user selected, constant speed that ranges from fractional
microns per minute to one meter per minute. These systems continuously measure
the precise force being applied to, and the resulting deformation of, the test
material at various time intervals. They also analyze the results of the test,
and either print, graph or electronically display them.

Instron's static product offerings include the cost effective Series 4400
product line and the high-performance Series 5500 product line. The Series 5500
systems are usually used for research and development and are equipped with
sophisticated software and many accessories. Quality control applications
usually require fewer accessories and less breadth of application capability.

The prices of static systems generally range from $15,000 to $150,000. Static
systems and related accessories accounted for approximately 62%, 70%, and 69% of
the Company's revenue in 1998, 1997 and 1996, respectively.

                                       3
<PAGE>   4


DYNAMIC SYSTEMS - Dynamic (servohydraulic drive) systems allow repeated
deformation of the material being tested to simulate in-use conditions over an
extended period of time. These systems use a servo-controlled hydraulic
actuator, a load cell, grips, and electronic modules that control the test and
analyze the test data.

Software, computer control, and data analysis are features routinely added to
basic dynamic systems. The computer may be used to command actuator motion to
simulate real-life loading conditions. It is also used to store and analyze data
and display parameters of performance and endurance for test materials or test
components.

Utilizing the Company's engineering expertise, dynamic systems are often
customized to fit the need of a customer's particular test application. Machines
can be configured not only to stretch or compress the material being tested, but
also to simultaneously twist it or subject it to other forms of complex loading.

The dynamic product line includes structural testing or simulation systems.
These systems are used to simulate real life conditions while testing a wide
range of automotive components from suspension and steering systems to entire
vehicles. They typically consist of several actuators that push and pull the
structure at different points, and sensors that collect and transmit the
resulting data to a central processing unit.

The prices of dynamic systems generally range from $40,000 to $400,000 with very
complex structural testing systems ranging as high as several million dollars.
Dynamic systems and related accessories accounted for approximately 38%, 30% and
31% of the Company's sales in 1998, 1997 and 1996, respectively.

HARDNESS SYSTEMS - Instron is in the forefront of development for new
hardness-testing systems. These systems indent the surface of a material under a
controlled force. The size of the resulting indentation gives an indication of
the hardness of the surface of the material.

The Series 2000 hardness-testing machine takes advantage of Instron's advanced
electromechanical position and control technology and also incorporates
Instron's load cell technology.

The prices of hardness testing machines range from $2,000 to $20,000. The sales
of hardness systems and related accessories are included in the percentage
amounts for static systems set forth above.

SERVICE - In recent years, the Company has invested in new service offerings,
including calibration, extended warranties, software support, upgrade contracts,
training and telephone support. The service business accounted for approximately
16%, 17%, and 16% of the Company's total revenue in 1998, 1997, and 1996,

                                       4
<PAGE>   5

respectively. The service revenue is included in the percentage amounts for
static and dynamic systems set forth above.

OTHER PRODUCTS AND ACCESSORIES - Instron manufactures and sells a wide range of
other products and accessories. The products include durometers, impact testers,
and asphalt binder testers. Typical accessories include application software,
grips, fixtures, optical/video extensometers that measure precisely the
deformation of the material being tested without actually contacting it, robotic
devices that automatically feed test specimens to the systems, and environmental
control accessories. Accessories can be included with the initial purchase or
subsequently purchased in order to expand the capability of the original
machine.

The Company also has license agreements with third parties for the exclusive
sale of certain products, including software, in the material and structural
testing industry.

These other products and accessories for static and dynamic equipment purchased
separately from the original sale of equipment are included in the percentage
amounts for static and dynamic systems set forth above.

ACQUISITIONS

On August 4, 1998, the Company acquired substantially all the assets of Satec
Systems, Inc. of Grove City, Pennsylvania, for approximately $12.6 million in
cash. Satec is a manufacturer of a range of materials testing equipment sold
primarily in the United States with annual sales of approximately $18.0 million.
This acquisition has been accounted for under the purchase method of accounting
and, accordingly, the acquired assets and liabilities have been recorded at
their estimated fair values at the date of acquisition. The operating results of
Satec have been included in the Company's consolidated results of operations
from the date of acquisition.

IST was a joint venture company that Instron entered into in November 1996 with
Carl Schenck AG in the area of structural testing. On September 27, 1998, the
Company acquired the remaining 49% interest in Instron Schenck Testing Systems
("IST") from Carl Schenck A.G. of Darmstadt, Germany for $2.7 million in cash.
IST has become a world-class structures testing business with sales of more than
$55 million in 1998. This additional investment has been accounted for under the
purchase method of accounting and, accordingly, the acquired assets and
liabilities have been recorded at their estimated fair values at the date of
acquisition. The operations of IST for the fourth quarter of 1998 have been
consolidated into the Company's results of operations from the date of
acquisition. Prior to this acquisition the Company accounted for its 51%
interest in IST under the equity method of accounting.

RESEARCH AND DEVELOPMENT

The Company maintains major research and development staffs at its U.S. and
U.K. manufacturing facilities. These development staffs often work directly with
industrial and government researchers and the materials science departments of
universities to create leading edge solutions to materials testing applications.

Instron is a pioneer in the development and application of electronic
measurement and drive systems techniques in materials testing systems. The
Company has continuously designed, developed, and marketed state-of-the-art
testing systems, software, and accessories, including digitally controlled
static and dynamic testing systems. 

In 1998, the Company expensed $8,485,000 on research and development activities,
compared with $6,959,000 in 1997, and $8,616,000 in 1996. The Company has also
capitalized certain software development costs of $1,490,000. $637,000, and
$1,144,000 during 1998, 1997 and 1996, respectively. During these years, certain
Instron engineering resources have been utilized to develop new products for IST
in accordance with the joint venture agreement. The costs associated with the
development efforts were reimbursed by IST. If research and development expenses
were restated, for comparison purposes, by including software development costs
as period expenses, and by adjusting engineering expenses for the effect of IST
and Satec and the disposition of LMS, research and development expenses of the
ongoing business would have increased by 7.5% in 1998. In recent years, the
Company has focused its research and development expenditures on creating new
product platforms for static and dynamic product lines, developing new hardness
testing machines, developing new software and enhancements, and redesigning
products to reduce manufacturing costs. These new products and enhancements do
not, in the Company's opinion, present a significant risk that on-hand
inventory, which supports existing models, will be made obsolete because of the
interchangeability of parts and the lead time available before the introduction
of new products.

COMPETITIVE CONDITIONS

The Company competes with a number of other manufacturers, some of whom have
greater financial, technical and marketing resources than the Company. The
intensity of the competition varies by product line and by geographic area.
Competition in the United States is greatest in the dynamic line where the
Company has one major domestic competitor, MTS Systems Corporation. Competition
in foreign markets is greatest in Germany and Japan, where there are major local
manufacturers. The principal competitive factors are engineering excellence, the

                                       6
<PAGE>   7

quality and technical capability of the equipment, responsiveness to customer
needs, quality of service, and price performance.

BACKLOG

At December 31, 1998, the Company's backlog of orders was approximately
$74,477,000 compared with $28,748,000 at December 31, 1997. The increase in
backlog is due primarily to the inclusion of the IST and Satec backlogs in
December 31, 1998.

The Company anticipates that substantially all of its backlog as of December 31,
1998 will be shipped during 1999.

RAW MATERIALS

While the Company is dependent upon a limited number of suppliers for certain
components, it has not experienced significant problems in procurement or
delivery of any essential materials, parts or components. Substantially all
purchasing is accomplished on a competitive basis while maintaining a level of
inventory sufficient to provide support of customer servicing requirements and
meet scheduled delivery dates.

PATENTS AND TRADEMARKS

The Company has several patents in the United States and in foreign countries.
However, the Company relies principally on its engineering and technological
capabilities rather than on these patents to maintain its position in the
industry. The trademarks "Dynatup," "Shore," "Rockwell" and "Instron" and the
device mark are registered trademarks of the Company. Under current law, these
trademarks may be renewed indefinitely as long as they are maintained in use.

ENVIRONMENTAL CONSIDERATIONS

Compliance with federal, state and local provisions relating to protection of
the environment has not had, and is not expected to have, any material adverse
effects upon the production, capital expenditures, earnings, and competitive
position of the Company and its subsidiaries.

NUMBER OF EMPLOYEES

At December 31, 1998 the Company employed 1,421 people worldwide.

SEASONALITY

Historically, the Company's sales are highest in the fourth quarter of each year
due to the ordering pattern of its customers, which favors fourth quarter
deliveries before budget authorizations expire. Sales in the first quarter are
usually low as it takes time to rebuild in-process inventory levels after the
heavy fourth quarter delivery requirements have been satisfied. Also, third
quarter sales are generally low due to vacation patterns of both Company
production workers and customer technical personnel needed for acceptance
testing. The seasonal factors affecting sales are usually reflected in quarterly
net income.

FOREIGN OPERATIONS

Foreign operations represent a significant portion of the Company's business.
The Company's branches and subsidiaries outside of the United States accounted
for 55% of the Company's total revenue in 1998, 59% in 1997 and 61% in 1996. The
Company believes that the business and political risk of operating in most of
its current foreign markets is not, in the aggregate, materially greater than
the risk undertaken by the Company in the United States. The recent economic
turmoil in the Asian economies has increased the business risks associated with
operating in this region. The Company's principal foreign assets are located in
the United Kingdom and Germany.

Foreign exchange fluctuations can have a significant impact on the Company's
consolidated net assets and results of operations as reported in U.S. dollars.
However, the Company believes that these fluctuations generally have not had,
and it does not expect them to have, a significant economic effect on the
Company's business since foreign operations are generally financed, and revenues
and expenses are, for the most part, paid in local currencies, except for
intercompany purchases which are closely monitored. Financial information
concerning domestic and foreign operations appears in Notes 1 and 2 in the
"Notes to Consolidated Financial Statements" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations", included as part of
this report.

ITEM 2. PROPERTIES

The Company's corporate headquarters and principal United States manufacturing
facility is located at the junction of Routes 128 and 138 in Canton,
Massachusetts, approximately 15 miles from Boston. On March 27, 1998, the
Company sold 42 acres of excess land in Canton, Massachusetts for $13.5 million
in cash. The Company believes that the remaining 24 acres are sufficient for
current and future business requirements.

The Company's principal foreign facilities include 120,000 square feet of office
and manufacturing space located on seven acres of Company-owned land in High
Wycombe, England, approximately 30 miles west of London and 50,000 square feet
of office and manufacturing space leased in Darmstadt, Germany.

The Company has 35 sales offices and demonstration centers which are located
throughout the United States and in 17 foreign countries. The Company believes
that all properties are adequate and suitable for its present needs.

ITEM 3. LEGAL PROCEEDINGS

The registrant and its subsidiaries are not involved in any material pending
legal proceedings.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to a vote of security holders during the fourth
quarter of the year ended December 31, 1998.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
     OF OPERATIONS

RESULTS OF OPERATIONS

     The consolidated results for 1998 reflect, from the dates of
acquisition, the inclusion of Satec which was acquired in August 1998 and the
buyout of the remaining 49% of the IST joint venture in September 1998.

     During August 1998, the Company acquired Satec Systems, a materials testing
company supplying electromechanical and servohydraulic products primarily to the
metals industry. The business was acquired for $12.6 million in cash and the
consolidated results of Instron reflect Satec's activity for the last five
months of 1998. Satec's reported sales were $8,757,000 and net income was
$356,000 for the last five months of 1998. For information purposes, Satec's
annual sales for 1998 and 1997 were $18,642,000 and $17,064,000, respectively.

     IST was a joint venture company that Instron entered into in November 1996
with Carl Schenck AG in the area of structural testing. Both companies
contributed their structural testing business and signed contracts to provide
manufacturing, R&D and support services to the joint venture. During 1997 and
the first nine months of 1998, Instron owned 51% of IST and accounted for the
joint venture using the equity method of accounting. Instron's revenue from IST
was $11,395,000, $6,858,000 and $519,000 for the first nine months of 1998, the
total year of 1997, and the last two months of 1996, respectively. This revenue
reflects the shipment of systems from Instron to IST under the terms of a
manufacturing and supply agreement at substantially reduced gross margins
compared to normal customer margins, and commission income earned by Instron for
selling IST products. During the time that Instron owned 51% of the entity, IST
had operating losses, due in part to low margin orders contributed into the
joint venture, and the time and effort necessary to consolidate the operations
and technology of the two contributing partners. For 1998, 1997 and 1996,
Instron recorded net losses related to its 51% share of the joint venture
results of $902,000, $876,000 and $69,000, respectively.

     Instron exercised its option to purchase the remaining 49% of IST for $2.7
million in cash on September 27, 1998. Upon the completion of the acquisition,
the full results of operations from the IST business were included in
consolidated results of Instron, representing three months of activity in 1998.
IST broke even in the fourth quarter and is anticipated to make a contribution
to earnings in 1999. IST's customer revenue of $18,441,000 for the fourth
quarter of 1998 was included in Instron's reported results. For information
purposes, IST's annual revenues were $56,619,000 and $39,777,000 in 1998 and
1997, respectively.

     Financial comparisons of the results of fiscal 1997 and 1996 are impacted
by Instron's sale of its Laboratory MicroSystems division ("LMS") to Axiom
Systems in April 1997. LMS's revenues were $1,237,000 in the first quarter of
1997 and $5,625,000 in 1996. LMS had no significant impact on net income in
either year.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
     OF OPERATIONS

RESULTS OF OPERATIONS (continued)

     Total revenue of $183,029,000 in fiscal 1998 increased by 17.6% from
revenue of $155,660,000 in fiscal 1997 due primarily to the acquisitions of
Satec and IST. Total revenue in fiscal 1997 increased by 1.7% from revenue of
$153,113,000 in fiscal 1996.

     Bookings of new orders were $166,515,000 in fiscal 1998. Bookings on a pro
forma basis, including the annual bookings of IST and Satec, would have been
$212.7 million in 1998 compared to $220.1 million in 1997, a decrease of 3.4%.
This decrease is due largely to the impact of the economic downturn in the Asian
markets.

     The Company's backlog of orders was $74,477,000 at December 31, 1998, an
increase of 159.1% from 1997 due primarily to the inclusion of the IST and Satec
backlogs. The year end 1997 backlog decreased by 16.3% from 1996.

     The gross profit margins for the three years ended December 31, 1998 were
39.3%, 41.2% and 42.1%, respectively. The trend of decreasing margins is due
principally to the impact of supplying IST with structures systems at lower than
normal profit margins. Gross margins excluding LMS, IST and Satec were 44.3%,
42.7% and 42.8% in 1998, 1997 and 1996, respectively. This improvement in 1998
is due in part to improved service margins and the benefit of actions previously
taken to reduce manufacturing costs.

     The 1998 selling and administrative expenses of $48,869,000 increased by
9.5% from 1997 due principally to the inclusion of expenses relating to Satec
and IST. As a percentage of revenue, selling and administrative expenses
decreased to 26.7% in 1998, compared to 28.7% in 1997 and 29.3% in 1996. 

     Research and development expenses increased by 21.9% in 1998 and decreased
by 19.2% in 1997. The increase in 1998 is due primarily to the inclusion of the
development efforts of Satec and IST. The decrease in 1997 compared to 1996
resulted from certain Instron engineering resources ($2 million in 1997) being
utilized to develop new products for IST in accordance with the joint venture
agreement, which were reimbursed by IST. During the three years ended December
31, 1998, the Company has capitalized certain software development costs. (See
Note 1 of Notes to Consolidated Financial Statements). If research and
development expenses were restated, for comparison purposes, by including
capitalized software development costs as period expenses, by adjusting
engineering expenses for the effect of Satec and IST and the disposition of LMS
as previously discussed, research and development expenses of the ongoing
business would have increased by 7.5% in 1998. As a percentage of total revenue,
research and development expenditures, on a comparable basis, represented 7.0%,
6.4% and 6.4% in 1998, 1997 and 1996 respectively.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
     OF OPERATIONS

RESULTS OF OPERATIONS (continued)

     Operating income decreased by 23.3% to $9,646,000 in 1998, compared to
$12,571,000 in 1997 and $9,145,000 in 1996. As a percentage of total revenue,
operating income represented 5.3%, 8.1% and 6.8% in 1998, 1997 and 1996
respectively. Operating income for 1998 includes a special items charge of
$4,975,000 for the cost of consolidating European operations and to write down
the value of non-performing assets. The Company has closed down a manufacturing
plant in Germany, relocated sales and service personnel to another Instron
location in Germany, and moved the manufacturing operation to the United
Kingdom. The majority of these actions were completed in the fourth quarter and
substantially all cash disbursements are expected to be made by the end of the
first quarter of 1999. Before the effect of the special items charge, operating
income in 1998 was $14,621,000 or 8.0% of total revenue and increased by 16.3%
compared to 1997 due primarily to certain improved product and service margins
and the positive contribution of Satec and IST in the fourth quarter.

     A non-operating pre-tax gain of $11,076,000 was recorded in the first
quarter of 1998 on the sale of excess land in Canton, Massachusetts. Net
interest expense decreased by 72% in 1998 and by 22% in 1997. The net decrease
in both 1998 and 1997 was due to reduced interest expense resulting from lower
average borrowings and was further reduced by interest income received on notes
receivable and temporary bank deposits. Foreign exchange losses of $157,000 in
1998 resulted from the strengthening of the British pound against certain
European currencies. Foreign exchange losses of $185,000 in 1997 resulted from
the strengthening of the U.S. dollar against certain Asian currencies.

     Income before taxes was 11.1% of total revenue in 1998, compared to 7.4% in
1997 and 4.8% in 1996. Excluding the special items charge and the non-operating
gain on the sale of the land in 1998, as well as the special items charge in
1996, income before taxes as a percentage of total revenue was 7.8%, 7.4% and
6.0% in 1998, 1997 and 1996, respectively. The consolidated effective tax rate
was 43.6% compared to 38% in 1997 and 1996. This higher tax rate is due to
certain non-deductible expenses relating to the special items charge. A detailed
reconciliation of the Company's effective tax rate and the United States
statutory tax rate appears in Note 6 of Notes to Consolidated Financial
Statements.

     Instron reported net income of $11,459,000, or $1.62 per diluted share of
common stock, for the year ended December 31, 1998, compared with $7,164,000 or
$1.05 per diluted share in 1997. Net income in 1998 included a special items
charge to operations of $4,975,000 ($4,232,000 net of taxes) and a non-operating
gain on the sale of land of $11,076,000 ($6,867,000 net of taxes). If these
special items are excluded, net income in 1998 was $8,824,000, or $1.25 per
diluted share, an increase of 23.2% from 1997, due primarily to improved product
and service margins, the positive contribution of Satec and IST in the fourth
quarter, and a decline in net interest expense.

RESULTS OF OPERATIONS (continued)

     Net income in 1996 included a special items charge to operations of
$1.8 million ($1.1 million net of taxes). Excluding the effect of the special
items charge in 1996, net income increased by 25.6% in 1997 due primarily to
increased revenues of the on-going business, a decline in interest expense and
lower foreign exchange losses.

FINANCIAL CONDITION

     The Company's operating activities generated cash of $5.3 million and $17.0
million in 1998 and 1997, respectively. Investing activities used $6.8 million
in 1998 and $6.2 million in 1997, while financing activities provided $6.1
million in 1998 and used $10.6 million in 1997. The Company's primary source of
funds in 1998 and 1997 was net cash generated by operations, supplemented in
1998 by the net proceeds of the sale of excess land in Canton, Massachusetts.
The net cash generated by operations in 1998 consisted primarily of net income,
as adjusted for the non-cash effect of depreciation and amortization expense,
which was partially offset by an increase in accounts receivable.

     At December 31, 1998, accounts receivable were $65.8 million compared to
$48.2 million at year end 1997 which reflects higher fourth quarter revenue in
1998, and the consolidation of Satec and IST balance sheets. Inventories of
$36.1 million increased by $12.1 million due to the consolidation of Satec and
IST. The inventory turnover ratio increased to 2.97 from 2.87 at the end of
1997.

     The Company's principal investment activities during 1998 included the
purchase of Satec for $12.6 million, the buyout of the remaining 49% of IST for
$2.7 million, capital expenditures of $5.8 million, and the development of
software products for $1.5 million. The Company plans to make capital
expenditures of approximately $6.2 million in fiscal 1999, principally for
manufacturing equipment and information systems. In addition, the Company plans
to continue to develop and enhance its software products and pursue its strategy
of acquisitions.

     The Company's total debt outstanding at year-end 1998 was $19.6 million
compared to $13.7 million at the end of 1997. The ratio of total debt to debt
plus equity, at year-end 1998 increased to 19.8% from 17.1% in 1997. The
increase in debt was primarily due to funding acquisitions in 1998.

     The Company maintains a multi-currency revolving credit and term loan
facility that provides for borrowings of up to $35.0 million. At December 31,
1998 the Company had outstanding domestic and international borrowings of $13.2
million and at December 31, 1997 had outstanding domestic borrowings of $7.6
million under this facility which were classified as long-term. The Company has

FINANCIAL CONDITION (continued)

additional overdraft and borrowing facilities for allowing advances of
approximately $32.0 million of which $6.4 million and $6.1 million were
outstanding and classified as short-term borrowings at December 31, 1998 and
1997, respectively.

     The Company believes its present capital resources and anticipated
operating cash flows are sufficient to meet its current and future cash
requirements to finance operations, capital expenditures and acquisitions.

     On March 27, 1998, the Company sold 42 acres of excess land in Canton,
Massachusetts, for $13.5 million in cash.

     Approximately 22% of the Company's total orders came from Asian markets in
1997. Bookings from this region declined by 30% in 1998 compared to 1997. At the
same time, however, IST doubled new order bookings in this part of the world.
The current strength in North America and Europe is expected to continue in
1999, though the Company is not expecting any significant recovery in bookings
from the Asian markets in 1999.

     Earnings are anticipated to maintain their upward momentum in 1999,
reflecting benefits from manufacturing cost improvement programs and the full
year benefit of the recent acquisitions.

     EURO CURRENCY ISSUE. On January 1, 1999, eleven of the fifteen member
countries of the European Union established fixed conversion rates between their
existing currencies ("legacy currencies") and one common currency - the euro.
The euro now trades on currency exchanges and may be used in business
transactions. Beginning in January 2002, new euro-denominated bills and coins
will be issued, and legacy currencies will be withdrawn from circulation. The
Company's operating subsidiaries affected by the euro conversion have
established plans to address the systems and business issues raised by the euro
currency conversion.

     These issues include, among others, (i) the need to adapt computer and
other business systems and equipment to accommodate euro-denominated
transactions; and (ii) the competitive impact of cross-border price
transparency, which may make it more difficult for businesses to charge
different prices for the same products on a country-by-country basis,
particularly once the euro currency is issued in 2002. The Company anticipates
that the euro conversion will not have a material adverse impact on its
financial condition or results of operations.

     YEAR 2000 INFORMATION AND READINESS DISCLOSURE ACT. Instron supports the
exchange of information relating to the Year 2000 issue and designates the
information following below as the Year 2000 Readiness Disclosure within the
meaning of the Year 2000 Information and Readiness Disclosure Act. Information
set forth herein regarding the Year 2000 compliance of non-Instron products and
services are "republications" under the Year 2000 Information and Readiness
Disclosure Act and are based on information supplied by other companies about
the products and services they offer. Instron has not independently verified the
contents of these republications and takes no responsibility for the accuracy or
completeness of information contained in such republications.

     YEAR 2000 ISSUE READINESS DISCLOSURE. The term "Year 2000 issue" is a 
general term used to describe various business-related problems that may result 
from the improper processing by computer systems of dates after 1999. The Year 
2000 issue affects virtually all companies and all organizations. The Company 
has identified its Year 2000 non-compliance risks in four categories: (i) 
internal business systems, (ii) internal electronic equipment and embedded chip 
technology; (iii) external non-compliance by the Company's suppliers, and (iv) 
software systems products supplied by the Company to its customers.

     INTERNAL BUSINESS SYSTEMS:- The Company has an active, ongoing program to
insure that its business systems will be Year 2000 compliant. Instron began this
program to identify and correct Year 2000 issues in 1996. In accordance with
this program, the Company is following a four step process to address the Year
2000 Issue. The first stage consisted of auditing the major business systems and
telecommunication switches. This stage identified a couple of minor issues but
due to the installation of a new ERP system in 1996 at our two primary
manufacturing sites, the exposure is minimal and is expected to be corrected by
June 1999. The second stage, begun in September 1997, is an audit of all
departmental systems and network operating systems. This audit is nearing
completion and has formed the basis for the third stage which identifies the
corrective actions required, and outlines the necessary plan of action. The
final stage, which has started, will include the implementation and testing of
all required modifications.

     Accordingly, the Company is confident that its internal business systems
will be made Year 2000 compliant in a timely manner and in any event, no later
than July 1999. The Company anticipates making capital expenditures of
approximately $500,000 in 1999 to upgrade computing, networking and
telecommunications systems as part of the plan to address the Year 2000 issue.
Although the costs associated with identifying and implementing the necessary
plan of action are not expected to be material to the Company's financial
position, there can be no assurance to this effect.

     The Company has initiated an audit of the business systems of the two
recent acquisitions, Satec and IST. So far, there has been no indication of any
major Year 2000 issue that cannot be resolved in a timely manner.

     OF OPERATIONS

FINANCIAL CONDITION (continued)

     INTERNAL ELECTRONIC EQUIPMENT AND EMBEDDED CHIP TECHNOLOGY:- The audit
process has identified certain telecommunication equipment that needs to be
upgraded to address the Year 2000 issue. The Company plans to replace this
equipment by June 1999, and is currently reviewing such office and facilities
equipment as machine tools, photocopiers, security systems and other systems
which may be impacted by the Year 2000 issue. The Company estimates that the
total cost of completing any modifications, upgrades or replacements of this
equipment will not have a material adverse effect on the Company's business or
results of operations. This estimate is being monitored and will be revised as
additional information becomes available. 

     SUPPLIERS:- The Company has started a communication program with key
suppliers of computers, equipment, parts and material used, operated and
maintained by the Company. This program is intended to identify and, to the
extent possible, resolve issues with suppliers involving the Year 2000 problem.
However, the Company has limited or no control over the actions of these third
party suppliers. Any failure of these suppliers to resolve Year 2000 issues with
their systems in a timely manner could have a material adverse effect upon the
Company's business, financial condition and results of operation.

     COMPANY SUPPLIED SYSTEMS AND SOFTWARE TO CUSTOMERS:- The Company believes
that it has substantially identified and resolved all potential Year 2000 Issues
with all of the software products that it is currently developing and marketing.
Existing software on installed machines may not be Year 2000 compliant and
communication programs have been initiated to advise customers on how to upgrade
or replace their existing systems. Management believes that it is not possible
to determine with complete certainty that all Year 2000 issues affecting the
Company's products have been identified due to the complexity of these systems
and the fact that these products interact with other third party vendor products
and operate on computer systems which are not under the Company's control. Any
such failures to identify or remediate Year 2000 problems affecting the
Company's systems and software products could have a material adverse effect
upon the Company's business, financial conditions and results of operations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
     OF OPERATIONS

FINANCIAL CONDITION (continued)

     The information presented above sets forth the key steps taken by the
Company to address the Year 2000 Issue. There can be no absolute assurance that
the Company has identified all the issues, can resolve them in a timely manner,
and that there will be no failures or disruptions to operations which could
result in a material adverse effect upon the company's business, financial
condition, results of operations, and business prospects.

     CONTINGENCY PLANS:- The Company intends to develop contingency plans for
significant business risks identified by the Company that might result from
Year-2000 related events. Because the Company has not yet identified any
specific business function that will be materially at risk of significant
Year-2000 related disruptions, and because a full assessment of the Company's
risk from potential Year 2000 failures is still in process, the Company has not
yet developed detailed contingency plans specific to Year 2000 problems. In the
event that the Company concludes that one or more contingency plans are
required, development of such contingency plans is currently scheduled to occur
no later than September, 1999 or as otherwise appropriate.

QUANTITATIVE AND QUALITATIVE INFORMATION ABOUT MARKET RISK.

     The Company is exposed to market risk related to changes in foreign
currency exchange rates. The Company enters into foreign exchange contracts to 
manage and reduce the impact of changes in foreign currency exchange rates. The 
Company does not enter into derivatives or other financial instruments for 
trading or speculative purposes. The exposures are associated with certain 
accounts receivable denominated in local currencies and certain foreign 
revenue transactions.

     At December 31, 1998, the face amount of outstanding forward currency
contracts to buy and sell U.S. dollars, Japanese yen and certain European
currencies was $6.3 million. A 10% fluctuation in exchange rates for these
currencies would change the fair value by approximately $0.3 million. However,
any change in the fair value of the contracts would be offset by changes in the
underlying value of the transactions being hedged.

     The hypothetical movement disclosed above was estimated by calculating the
fair value of the forward currency contracts at December 31, 1998, and comparing
that with those calculated using hypothetical forward currency exchange rates.

NEW ACCOUNTING PRONOUNCEMENTS.
      
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. The statement
is effective for fiscal years beginning after June 15, 1999. Management is
currently evaluating the effects of this change on its recording of derivatives
and hedging activities. The Company will adopt SFAS No. 133 for its fiscal year
ending December 31, 2000.

     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position (SOP) 98-1, "Internal Use Software," which provides
guidance on the accounting for the costs of software developed or obtained for
internal use. SOP 98-1 is effective for fiscal years beginning after December
15, 1998. Management does not expect the statement to have a material impact on
its financial position or results of operations.

FORWARD LOOKING STATEMENTS.

     Certain statements contained in this Annual Report are "forward-looking"
statements within the meaning of the federal securities laws and are made in
reliance upon the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. No assurances can be given that actual results will not
differ materially from those projected in the forward-looking statements
contained in this Annual Report. Certain factors that might cause such a
difference include: the level of bookings worldwide for Instron, Satec and IST,
particularly in Asia; the success of the automobile industry which is the major
purchaser of IST products; the operating results of Satec and IST; the impact of
fluctuations in exchange rates and the uncertainties of operating in a global
economy, including fluctuations in the economic conditions of the foreign and
domestic markets served by the Company which can affect the demand for its
products and services; the Company's ability to successfully integrate the
products and operations of Satec; the impact of Year 2000 issues; and the
Company's ability to identify and successfully consummate strategic
acquisitions.

                       REPORT OF INDEPENDENT ACCOUNTANTS


TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF INSTRON CORPORATION:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, stockholders' equity and cash flows present
fairly, in all material respects, the financial position of Instron Corporation
and its subsidiaries (the "Company") at December 31, 1998 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the
accounts of all domestic and foreign subsidiaries. Significant intercompany
transactions and balances are eliminated. Certain reclassifications were made to
prior years' amounts to conform with the 1998 presentation.

USE OF ESTIMATES The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make certain
estimates and assumptions that effect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reported periods. Actual results could differ
from those estimates.

FOREIGN CURRENCY TRANSLATION Assets and liabilities of the Company's principal
foreign operations are translated at exchange rates prevailing at the end of the
period. Income statement items are translated using average quarterly exchange
rates. Translation gains or losses are included in accumulated other
comprehensive income (loss) and are reported in income only if the underlying
foreign investment is sold or liquidated.

FOREIGN EXCHANGE RISK MANAGEMENT The Company regularly enters into forward
contracts primarily denominated in Japanese yen and certain European currencies
to hedge firm sales and purchase commitments. Forward currency contracts have
maturities of less than one year. These contracts are used to reduce the
Company's risk associated with exchange rate movements, as gains and losses on
these contracts are intended to offset exchange losses and gains on underlying
exposures. The Company does not engage in currency speculation. The Company's 
policy is to defer gains and losses on these contracts until the corresponding 
losses and gains are recognized on the items being hedged. Both the contract 
gains and losses and the gains and losses on the items being hedged are 
included in selling and administrative expenses. The unrealized losses were not 
material in 1998 and 1997 as the fair value of these contracts were 
approximately equal to the fair value of the underlying exposures.

At December 31, 1998, the face amount of outstanding forward currency contracts
to sell U.S. dollars for non U.S. currencies was $3.2 million, Japanese yen for
German deutschemarks was $1.9 million and French francs for British pounds was
$0.7 million. At December 31, 1998, the face amount of outstanding forward
currency contracts to buy German deutschemarks for U.S. dollars was $2.4
million, German deutschemarks for Japanese yen $1.9 million, British pounds for
U.S. dollars was $0.9 million, British pounds for French francs was $0.7 million
and British pounds for German deutschemarks was $0.4 million.





                                       28

CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments
purchased with an original maturity of three months or less to be cash
equivalents.

CONCENTRATION OF CREDIT RISK Financial instruments which potentially subject the
Company to a concentration of credit risk principally consist of cash, cash
equivalents and trade receivables. The Company places its temporary cash
investments with major banks throughout the world, in high quality, liquid
instruments. The Company sells to a broad range of customers throughout the
world and performs ongoing credit evaluations to minimize the risk of loss. The
Company makes use of various devices such as letters of credit to protect its
interests, principally on sales to foreign customers. In addition, the Company
has certain receivables, payables, borrowings and other assets and liabilities
denominated in foreign currencies, which are not hedged and therefore are
subject to exchange rate fluctuations.

INVENTORIES Inventories are valued at the lower of cost or market (net
realizable value). The last-in, first-out (LIFO) method of determining cost is
used for certain inventories in the United States and Asian branches. The
Company uses the first-in, first-out (FIFO) method for all other locations.

GOODWILL AND INTANGIBLE ASSETS. Intangible assets are stated at cost
and amortized using the straight-line method over the assets estimated useful
lives which range from 4 to 10 years. The Company evaluates the possible
impairment of long-lived assets, including intangible assets, whenever events
or circumstances indicate the carrying value of the assets may not be
recoverable. Impairment of purchased technology amounts and goodwill is
measured on the basis of whether anticipated future undiscounted operating cash
flows expected from the acquired business will recover the recorded respective
intangible asset balances over the remaining amortization period. At December
31, 1998, no amounts have been determined impaired.  Amortization of goodwill
and other intangibles was $2,295,000, $1,974,000 and $2,254,000 in 1998, 1997
and 1996, respectively.

PROPERTY, PLANT AND EQUIPMENT Depreciation is computed principally using the
straight-line method over the estimated useful lives of 10 to 25 years for land
improvements, 10 to 40 years for buildings and improvements and 3 to 15 years
for machinery and equipment. Maintenance and repairs are expensed as incurred.
Depreciation expense was $4,239,000, $4,341,000 and $4,619,000 for the years
ended December 31, 1998, 1997 and 1996, respectively. Upon retirement or
disposition, the cost and related accumulated depreciation of the assets
disposed of are removed from the accounts, with any resulting gain or loss
included in operations. On March 27, 1998, the Company sold 42 acres of excess
land in Canton, Massachusetts for $13.5 million.

SOFTWARE DEVELOPMENT COSTS Certain software development costs are capitalized
and then amortized over future periods. Amortization of capitalized software
costs is computed on a product-by-product basis over the estimated economic life
of the product, generally three years. Unamortized software costs included in
other assets were $2,272,000, $1,574,000 and $2,473,000 at December 31, 1998,
1997 and 1996, respectively.


                                       29
<PAGE>   30

Software development costs of $1,490,000, $637,000 and $1,144,000 were
capitalized during 1998, 1997 and 1996, respectively. The amounts amortized and
charged to expense in 1998, 1997 and 1996 were $792,000, $725,000, and
$1,350,000, respectively.

REVENUE RECOGNITION Revenue from product sales are recognized at time of
shipment. Revenue from services are recognized as services are performed and
ratably over the contract period for service maintenance contracts.

INCOME TAXES Deferred income taxes are provided using the liability method,
which estimates future tax effects of differences between financial statement
carrying amounts and the tax basis of existing assets and liabilities. Tax
credits are recorded as a reduction in income taxes.

Provisions are made for the U.S. income tax liability on earnings of foreign
subsidiaries, except for locations where the Company has designated earnings to
be permanently invested. Such earnings amounted to approximately $22,803,000 at
year-end 1998.

EARNINGS PER SHARE. Basic earnings per share is computed by dividing net income
by the weighted average number of common shares outstanding during the period.
Diluted earnings per share is computed by dividing net income by the weighted
average number of common shares plus the dilutive effect of common share
equivalents outstanding using the "treasury stock method." 

The following is a reconciliation of the basic and diluted EPS calculations:

At December 1998, 4,500 Options were not included in the calculation of diluted
earnings per share as they were antidilutive.

FAIR VALUE.  The Company's financial instruments consist primarily of cash and
cash equivalents, trade receivables, trade payables and debt. The carrying
amounts of these instruments approximates fair value.

COMPREHENSIVE INCOME (LOSS). In June 1997, the Financial Accounting Standards
Board issued SFAS 130, "Reporting Comprehensive Income," which is effective for
periods beginning after December 15, 1997. The statement establishes standards
for reporting and displaying comprehensive income and its components (revenues,
expenses, gains, and losses) in a full set of general-purpose financial
statements. The statement requires that all components of comprehensive income
be reported in a financial statement that is displayed with the same prominence
as other financial statements. The Company has adopted SFAS 130 in the
accompanying financial statements.

PENSION PLAN.  In February 1998, the Financial Accounting Standards Board issued
SFAS 132, "Employers' Disclosures about Pensions and Other Postretirement
Benefits" which is effective for periods beginning after December 15, 1997. The
statement standardizes employer disclosure requirements about pension and other
postretirement benefit plans by requiring additional information on changes in
the benefit obligations and fair values of plan assets and eliminating certain
disclosures that are no longer useful. It does not change the measurement of
recognition of those plans. The Company has adopted SFAS 132 in the accompanying
financial statements.

2. INDUSTRY SEGMENT AND FOREIGN OPERATIONS

SFAS 131 establishes standards for reporting information about operating
segments in annual financial statements of public business enterprises. It also
establishes standards for related disclosures about products and service,
geographic areas, and major customers. The Company evaluated its business
activities that are regularly reviewed by the Chief Executive Officer for which
discrete financial information is available. As a result of this evaluation, the
Company determined that is has two operating segments: Materials Testing and
Structural Testing.

Instron's Materials Testing business manufactures and markets material testing
instruments (electromechanical, sevohydraulic, hardness and impact), software
and accessories. The structural testing business manufactures and markets
systems for simulating real-life testing of components and products. The
economic characteristics, production processes, core technology, types and
classes of customers, method of distribution and regulatory environments are
similar for both of these operating segments which operate within the material
testing industry. As a result of these similarities, both segments have been
aggregated into one reporting segment for financial statement purposes. 

The following table summarizes the Company's operations by significant
geographic location for the years ended December 31:

                                        =======   =======
</TABLE>


Inventories valued at LIFO amounted to $9,056,000 and $9,395,000 at December 31,
1998 and 1997, respectively. The excess of current cost over stated LIFO value
was $5,205,000 at December 31, 1998 and $5,247,000 at December 31, 1997.

4.   BORROWING ARRANGEMENTS

The Company maintains a multicurrency revolving credit and term loan facility
that provides for borrowings of up to $35,000,000 through April 2000. Borrowings
outstanding as of April 2000 convert to a term loan payable in sixteen equal
quarterly installments. Interest on borrowings under the agreement is based upon
either base rates, money market rates, or other short-term borrowing rates.

Facility fees under this agreement are 1/4 of 1% per annum. The Company has met
the various covenants in the agreement, the most restrictive of which requires a
minimum level of tangible net worth. At December 31, 1998 and 1997,
respectively, outstanding domestic borrowings of $8,375,000 and $7,600,000 with
a weighted average interest rate of 6.10% and 6.61%, and outstanding European
borrowings of $4,841,000 in 1998 with a weighted average interest rate of 4.75%,
were classified as long-term debt. Long-term debt maturing under the credit
agreement in each of the five years subsequent to December 31, 1998, assuming
outstanding borrowings at December 31, 1998 are unchanged at April 2000, is
$2,478,000 in 2000, $3,304,000 in 2001, 2002 and 2003.

The Company's subsidiaries have other overdraft and borrowing facilities
allowing advances up to approximately $32,000,000. At December 31, 1998, the
outstanding portion of these facilities was $6,416,000, due currently. Bank
guarantees outstanding at December 31, 1998, for which the Company is
contingently liable, amounted to $10,976,000 and relate principally to
performance contracts.

5.   OPERATING LEASE COMMITMENTS

Rental expense amounted to $3,998,000, $3,697,000 and $3,348,000 for the years
ended December 31, 1998, 1997 and 1996, respectively. As of December 31, 1998,
minimum annual commitments under noncancellable operating leases with terms of
more than one year are:

A valuation reserve has been established where, based upon available evidence,
it is more likely than not that some or all of the deferred tax assets will not
be realized. The valuation allowance relates primarily to foreign tax benefits.

7.   EMPLOYEE PENSION AND RETIREMENT PLANS

The Company maintains qualified noncontributory defined benefit pension plans
covering United States employees and employees of Instron's United Kingdom
subsidiary. The benefits are based on years of service and final average
compensation at the date of retirement. The Company's general policy is to fund
the pension plans to the extent such contributions are deductible under
standards established by the Internal Revenue Service in the U.S. and the Inland
Revenue in the U.K. Plan assets in the U.S. consist of mutual funds which invest
primarily in common stocks, corporate bonds, U.S. government notes and temporary
cash investments. In the U.K., plan assets are invested in funds whose assets
consist primarily of common stocks, bonds and other securities. Employees of the
Japan subsidiary receive lump sum payments as a multiple of annual salary at
retirement or termination, based on years of service. These Japanese benefits
are unfunded.

Net periodic pension costs include the following components:

8.   STOCK OPTION PLANS

The Company accounts for stock-based compensation using the intrinsic value
method. Accordingly, compensation cost for stock options is measured as the
excess, if any, of the quoted market price of the Company's stock at the date of
the grant over the amount an employee must pay to acquire the stock.

The Company has two stock options plans currently in effect under which future
grants may be issued: the 1992 Stock Incentive Plan and the 1979 Non-Qualified
Plan. A total of 1,391,500 shares has been authorized by the Company for grants
of options or shares. Stock Options granted during 1998, 1997 and 1996 generally
have a maximum term of eight years and vest equally over four years.

A summary of the Company's stock option activity for the years ended December 31

                                         ========

At December 31, 1998, 1997 and 1996, respectively, there were 502,735, 656,902
and 526,045 options exercisable with a weighted average exercise price of
$11.84, $10.94 and $10.58. Exercise prices for options outstanding as of
December 31, 1998, ranged from $10.00 to $19.625. The weighted average remaining
contractual life of those options is 4.3 years.

The weighted average fair value at date of grant for options granted during
1998, 1997 and 1996 was $7.39, $5.04 and $5.79 per option, respectively. The
fair value of these options at date of grant was estimated using the
Black-Scholes model with the following weighted average assumptions for 1998,
1997 and 1996, respectively: risk-free interest rates of 5.07%, 5.70% and 6.50%;
dividend yields of 0.97%, 1.31% and 1.19%; volatility factors of the expected
market price of the Company's common stock of .35, .31 and .30; and a weighted
average expected life of the options of 7.9, 8.0 and 7.8 years.

Had compensation cost for the Company's stock option plans been determined based
on the fair value at the grant date for awards in 1998, 1997 and 1996, the
Company's net income and earnings per share would have been reduced to the pro
forma amounts indicated below:
                                            1998     1997     1996
                                         -------   ------   ------
     Net income - pro forma              $10,871   $6,691   $4,105

     Earnings per share - basic          $  1.63   $ 1.04   $  .64

     Earnings per share - diluted        $  1.54   $  .99   $  .63

The pro forma effect on net income for 1997 and 1996 is not representative of
the pro forma effect on net income in future years because it does not take into
consideration pro forma compensation expense related to grants made prior to
1995.

On May 14, 1997 and October 29, 1997, respectively, the Company issued 250,000
and 20,500 shares of restricted stock to key employees, which resulted in
$3,414,000 of non-cash deferred compensation to be recognized as operating
expense over a seven year period. Vesting is accelerated upon change in control
or if certain performance criteria are met.

9.   ACQUISITIONS

On August 4, 1998, the Company acquired substantially all the assets of Satec
Systems, Inc. of Grove City, Pennsylvania, for approximately $12.6 million in
cash. Satec is a manufacturer of a range of materials testing equipment sold
primarily in the United States with annual sales of approximately $18.0 million.
This acquisition has been accounted for under the purchase method of accounting
and, accordingly, the acquired assets and liabilities have been recorded at
their estimated fair values at the date of acquisition. In conjunction with this
acquisition the Company recorded $7.2 million of goodwill which is being
amortized over ten years. The operating results of Satec have been included in
the Company's consolidated results of operations from the date of acquisition.

On September 27, 1998, the Company acquired the remaining 49% interest in IST
from Carl Schenck A.G. of Darmstadt, Germany for $2.7 million in cash. The book
value of net assets acquired were equal to the consideration paid. IST has
become a world-class structures testing business with sales of more than $55
million in 1998. This additional investment has been accounted for under the
purchase method of accounting and, accordingly, the acquired assets and
liabilities have been recorded at their estimated fair values at the date of
acquisition. The operations of IST for the fourth quarter of 1998 have been
consolidated into the Company's results of operations from the date of
acquisition. Prior to this acquisition the Company accounted for its 51%
interest in IST under the equity method of accounting.

10.       NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. The statement
is effective for fiscal years beginning after June 15, 1999. Management is
currently evaluating the effects of this change on its recording of derivatives
and hedging activities. The Company will adopt SFAS No. 133 for its fiscal year
ending December 31, 2000.

In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 98-1, "Internal Use Software," which provides
guidance on the accounting for the costs of software developed or obtained for
internal use. SOP 98-1 is effective for fiscal years beginning after December
15, 1998. This statement does not have a material impact on the Company's
financial position or results of operations.

11.       SPECIAL ITEMS CHARGES

During the first quarter of 1998, the Company recorded a special items charge to
operations to undertake a consolidation of its European operations and
write-down the value of certain non-performing assets. A pre-tax charge of
$4,975,000 was taken in the quarter ended March 28, 1998 to cover these actions.
The special items charge includes termination benefits, the costs to exit a
manufacturing facility, other asset impairments and other related costs. The
Company has closed down a manufacturing plant in Germany, relocated sales and
service support personnel to another Instron location in Germany and has moved
the manufacturing operation to the United Kingdom. During 1998 the Company paid
$1.4 million for termination benefits and related costs and $1.6 million for the
costs to shutdown and exit a manufacturing facility in Germany. In addition, the
Company wrote-off $1.0 million of non-performing assets in 1998, primarily
relating to its interest in Lightspeed Simulation Systems. The balance of the
Special Items reserve relates primarily to the Company's obligation under a
long-term lease agreement in Germany, partially offset by estimated income under
a sub-lease arrangement.

In March 1996, the Company recognized a $1,812,000 special items charge to
implement a work force reduction and consolidate certain manufacturing
operations.

To the Board of Directors and Stockholders

Our audits of the consolidated financial statements referred to in our report

                          EXECUTIVE SEVERANCE AGREEMENT
                          -----------------------------


     EXECUTIVE SEVERANCE AGREEMENT made as of May 14, 1998 by and between
Instron Corporation, a Massachusetts corporation with its principal place of
business in Canton, Massachusetts (the "Company"), and James M. McConnell of 
8 Pine Hill Drive, Needham, Massachusetts 02192 (the "Executive").

     1. Purpose. The Company considers it essential to the best interests of its
stockholders to foster the continuous employment of key management personnel.
The Board of Directors of the Company (the "Board") recognizes, however, that,
as is the case with many publicly held corporations, the possibility of a Change
in Control (as defined in Section 2 hereof) exists and that such possibility,
and the uncertainty and questions which it may raise among management, may
result in the departure or distraction of management personnel to the detriment
of the Company and its stockholders. Therefore, the Board has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of members of the Company's management, including the
Executive, to their assigned duties without distraction in the face of
potentially disturbing circumstances arising from the possibility of a Change in
Control. Nothing in this Agreement shall be construed as creating an express or
implied contract of employment and, except as otherwise agreed in writing
between the Executive and the Company, the Executive shall not have any right to
be retained in the employ of the Company.

     2. Change in Control. A "Change in Control" shall be deemed to have
occurred in any one of the following events:

     (a) any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
the Securities Exchange Act of 1934 (the "Act")) becomes a "beneficial owner"
(as such term is defined in Rule 13d-3 promulgated under the Act) (other than
the Company, any trustee or other fiduciary holding securities under an employee
benefit plan of the Company, or any corporation owned, directly or indirectly,
by the stockholders of the Company in substantially the same proportions as
their ownership of stock of the Company), directly or indirectly, of securities
of the Company representing fifty percent (50%) or more of the combined voting
power of the Company's then outstanding securities;

     (b) persons who, as of March 4, 1998, constituted the Company's Board (the
"Incumbent Board") cease for any reason, including without limitation as a
result of a tender offer, proxy contest, merger or similar transaction, to
constitute at least a majority of the Board, provided that any person becoming a
director of the Company subsequent to March 4, 1998 whose election was approved
by at least a majority of the directors then comprising the Incumbent Board
shall, for purposes of this Agreement, be considered a member of the Incumbent
Board;

<PAGE>   2

     (c) the stockholders of the Company approve a merger or consolidation of
the Company with any other corporation or other entity, other than (a) a merger
or consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than 80% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (b) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
"person" (as hereinabove defined) acquires more than 50% of the combined voting
power of the Company's then outstanding securities; or

     (d) the stockholders of the Company approve a plan of complete liquidation
of the Company or an agreement for the sale or disposition by the Company of all
or substantially all of the Company's assets.

     3. Terminating Event. A "Terminating Event" shall mean any voluntary or
involuntary termination of the Executive's employment occurring subsequent to a
Change in Control as defined in Section 2, except that a Terminating Event shall
not be deemed to have occurred solely as a result of the Executive being an
employee of any direct or indirect successor to the business or assets of the
Company, rather than continuing as an employee of the Company following a Change
in Control.

     4. Severance Payment. In the event a Terminating Event occurs within
twenty-four (24) months after a Change in Control,

     (a) the Company shall pay to the Executive an amount equal to two (2) times
the "base amount" (as such term is defined in Section 280G(b)(3) of the Internal
Revenue Code of 1986, as amended (the "Code")) applicable to the Executive (the
"Base Amount"), payable in one lump-sum payment. Said amount shall be paid no
later than thirty-one (31) days following the Date of Termination (as such term
is defined in Section 8(b)); and

     (b) the Company shall pay to the Executive all reasonable legal and
arbitration fees and expenses incurred by the Executive in successfully
obtaining or enforcing any right or benefit provided by this Agreement.

     5A. Additional Benefits. This Section 5A shall apply solely to the extent
the sum of (i) the payments made by the Company to or for the benefit of the
Executive under this Agreement (the "Severance Payment") and (ii) the value, as
calculated in accordance with Section 280G of the Code, of the benefits and
payments received by the Executive as a result of a Change in Control under any
other agreement or plan (the "Other 280G Benefits") (the sum of such Severance
Payment and the Other 280G Benefits are referred to as the "Total Severance
Benefits"), exceed 330% of the Base Amount (the "Threshold Amount").

                                        2
<PAGE>   3

     (a) In the event the Total Severance Benefits exceed the Threshold Amount,
then the Executive shall be entitled to receive an additional payment (a
"Gross-Up Payment") such that the net amount retained by the Executive, after
deduction of the excise tax imposed by Section 4999 of the Code (the "Excise
Tax") on the Total Severance Benefits, any Federal, state and local income tax,
employment tax and Excise Tax upon the payment provided by this subsection, and
any interest and/or penalties assessed with respect to such Excise Tax, shall be
equal to the Total Severance Benefits.

     (b) Subject to the provisions of Section 5A(c), all determinations required
to be made under this Section 5A, including the amount of such Gross-Up Payment,
shall be made by the Company's independent accounting firm (the "Accounting
Firm") which shall provide detailed supporting calculations both to the Company
and the Executive within 15 business days of the Date of Termination, if
applicable, or at such earlier time as is reasonably requested by the Company or
the Executive. For purposes of determining the amount of the Gross-Up Payment,
the Executive shall be deemed to pay federal income taxes at the highest
marginal rate of federal income taxation applicable to individuals for the
calendar year in which the Gross-Up Payment is to be made and state and local
income taxes at the highest marginal rates of individual taxation in the state
and locality of the Executive's residence on the Date of Termination, net of the
maximum reduction in federal income taxes which could be obtained from deduction
of such state and local taxes. The Gross-Up Payment, as determined pursuant to
this Section 5A(b), shall be paid to the Executive within five days of the
receipt of the Accounting Firm's determination. Any determination by the
Accounting Firm shall be binding upon the Company and the Executive. As a result
of the uncertainty in the application of Section 4999 of the Code at the time of
the initial determination by the Accounting Firm hereunder, it is possible that
Gross-Up Payments which will not have been made by the Company should have been
made (an "Underpayment"). In the event that the Company exhausts its remedies
pursuant to Section 5A(c) and the Executive thereafter is required to make a
payment of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred, consistent with the calculations required to be
made hereunder, and any such Underpayment, and any interest and penalties
imposed on the Underpayment and required to be paid by the Executive in
connection with the proceedings described in Section 5A(c), shall be promptly
paid by the Company to or for the benefit of the Executive.

     (c) The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment by the
Company of the Gross-up Payment. Such notification shall be given as soon as
practicable but no later than 10 business days after the Executive knows of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. The Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which he
gives such notice to the Company (or such shorter period ending on the date that
any payment of taxes with respect to such claim is due). If the Company notifies
the Executive in

                                        3
<PAGE>   4

writing prior to the expiration of such period that it desires to contest such
claim, the Executive shall:

      (i) give the Company any information reasonably requested by the Company
   relating to such claim,

      (ii) take such action in connection with contesting such claim as the
   Company shall reasonably request in writing from time to time, including,
   without limitation, accepting legal representation with respect to such claim
   by an attorney selected by the Company,

      (iii) cooperate with the Company in good faith in order effectively to
   contest such claim, and

      (iv) permit the Company to participate in any proceedings relating to such
   claim; provided, however that the Company shall bear and pay directly all
   costs and expenses (including additional interest and penalties) incurred in
   connection with such contest and shall indemnify and hold the Executive
   harmless, on an after-tax basis, for any Excise Tax or income tax, including
   interest and penalties with respect thereto, imposed as a result of such
   representation and payment of costs and expenses. Without limitation on the
   foregoing provisions of this Section 5A(c), the Company shall control all
   proceedings taken in connection with such contest and, at its sole option,
   may pursue or forego any and all administrative appeals, proceedings,
   hearings and conferences with the taxing authority in respect of such claim
   and may, at its sole option, either direct the Executive to pay the tax
   claimed and sue for a refund or contest the claim in any permissible manner,
   and the Executive agrees to prosecute such contest to a determination before
   any administrative tribunal, in a court of initial jurisdiction and in one or
   more appellate courts, as the Company shall determine; provided, however,
   that if the Company directs the Executive to pay such claim and sue for a
   refund, the Company shall advance the amount of such payment to the Executive
   on an interest-free basis and shall indemnify and hold the Executive
   harmless, on an after-tax basis, from any Excise Tax or income tax, including
   interest or penalties with respect thereto, imposed with respect to such
   advance or with respect to any imputed income with respect to such advance;
   and further provided that any extension of the statute of limitations
   relating to payment of taxes for the taxable year of the Executive with
   respect to which such contested amount is claimed to be due is limited solely
   to such contested amount. Furthermore, the Company's control of the contest
   shall be limited to issues with respect to which a Gross-Up Payment would be
   payable hereunder and the Executive shall be entitled to settle or contest,
   as the case may be, any other issues raised by the Internal Revenue Service
   or any other taxing authority.

     (d) If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 5A(c), the Executive becomes entitled to receive any
refund with respect to

                                        4
<PAGE>   5

such claim, the Executive shall (subject to the Company's complying with the
requirements of Section 5A(c)) promptly pay to the Company the amount of such
refund (together with any interest paid or credited thereon after taxes
applicable thereto). If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5A(c), a determination is made that
the Executive shall not be entitled to any refund with respect to such claim and
the Company does not notify the Executive in writing of its intent to contest
such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

     5B. Limitation on Benefits. This Section 5B shall apply solely to the
extent the Total Severance Benefits are less than or equal to the Threshold
Amount.

     (a) Solely in the event the Total Severance Benefits are less than or equal
to the Threshold Amount, it is the intention of the Executive and of the Company
that no payments of the Total Severance Benefits by the Company to or for the
benefit of the Executive under this Agreement or any other agreement or plan
shall be non-deductible to the Company by reason of the operation of Section
280G of the Code relating to parachute payments. Accordingly, and
notwithstanding any other provision of this Agreement or any such agreement or
plan, if by reason of the operation of said Section 280G, any such payments
exceed the amount which can be deducted by the Company, the Severance Payment
which the Executive is entitled to receive under this Agreement shall be reduced
by that amount which exceeds the maximum amount deductible by the Company under
Section 280G. To the extent that Severance Payments exceeding such maximum
deductible amount have been made to or for the benefit of the Executive, such
excess payments shall be refunded to the Company with interest thereon at the
applicable federal rate determined under Section 1274(d) of the Code, compounded
annually, or at such other rate as may be required in order that no such
payments shall be non-deductible to the Company by reason of the operation of
said Section 280G.

     (b) If any dispute between the Company and the Executive as to any of the
amounts to be determined under this Section 5B, or the method of calculating
such amounts, cannot be resolved by the Company and the Executive, either the
Company or the Executive, after giving three (3) days' written notice to the
other, may refer the dispute to a partner in the Boston office of a firm of
independent certified public accountants selected jointly by the Company and the
Executive. The determination of such partner as to the amount to be determined
under Section 5B(a) and the method of calculating such amounts shall be final
and binding on both the Company and the Executive. The Company shall bear the
costs of any such determination if the amount determined by such partner differs
to any material degree from the final amount proposed by the Company to the
Executive before submission to such partner. If there is no such material
difference, the costs of any such determination shall be evenly divided between
the Company and the Executive.

                                        5

     6. Term. This Agreement shall take effect on the date first set forth above
and shall terminate upon the earlier of (a) the termination by the Company of
the employment of the Executive prior to a Change in Control because of (A) a
willful act of dishonesty by the Executive with respect to any matter involving
the Company or any subsidiary or affiliate, or (B) conviction of the Executive
of a crime involving moral turpitude, or (C) the gross or willful failure by the
Executive to substantially perform the Executive's duties with the Company, or
(b) the resignation or termination of the Executive for any reason prior to a
Change in Control.

     7. Withholding. All payments made by the Company under this Agreement shall
be net of any tax or other amounts required to be withheld by the Company under
applicable law.

     8. Notice and Date of Termination; Disputes; Etc.

     (a) Notice of Termination. After a Change in Control and during the term of
this Agreement, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with this Section
8. For purposes of this Agreement, a "Notice of Termination" shall mean a notice
which shall indicate the reason for termination and the Date of Termination.

     (b) Date of Termination. "Date of Termination", with respect to any
purported termination of the Executive's employment after a Change in Control
and during the term of this Agreement, shall mean the date specified in the
Notice of Termination. In the case of a termination by the Company, The Date of
Termination shall not be less than thirty (30) days after the Notice of
Termination is given. In the case of a termination by the Executive, the Date of
Termination shall not be less than fifteen (15) days from the date such Notice
of Termination is given. In the event that the Executive gives a Notice of
Termination to the Company, the Company may unilaterally accelerate the Date of
Termination.

     (c) No Mitigation. The Company agrees that, if the Executive's employment
by the Company is terminated during the term of this Agreement, the Executive is
not required to seek other employment or to attempt in any way to reduce any
amounts payable to the Executive by the Company pursuant to Section 4(a) and (b)
hereof. Further, the amount of any payment provided for in this Agreement shall
not be reduced by any compensation earned by the Executive as the result of
employment by another employer, by retirement benefits, by offset against any
amount claimed to be owed by the Executive to the Company or otherwise.

     (d) Settlement and Arbitration of Disputes. Any controversy or claim
arising out of or relating to this Agreement or the breach thereof shall be
settled exclusively by arbitration in accordance with the laws of the
Commonwealth of Massachusetts by three arbitrators, one of whom shall be
appointed by the Company, one by the Executive and the third by the first two

                                        6
<PAGE>   7

arbitrators. If the first two arbitrators cannot agree on the appointment of a
third arbitrator, then the third arbitrator shall be appointed by the American
Arbitration Association in the City of Boston. Such arbitration shall be
conducted in the City of Boston in accordance with the rules of the American
Arbitration Association for commercial arbitrations, except with respect to the
selection of arbitrators which shall be as provided in this Section 8(d).
Judgment upon the award rendered by the arbitrators may be entered in any court
having jurisdiction thereof.

     9. Assignment; Prior Agreements. Neither the Company nor the Executive may
make any assignment of this Agreement or any interest herein, by operation of
law or otherwise, without the prior written consent of the other party, and
without such consent any attempted transfer shall be null and void and of no
effect. This Agreement shall inure to the benefit of and be binding upon the
Company and the Executive, their respective successors, executors,
administrators, heirs and permitted assigns. In the event of the Executive's
death after a Terminating Event but prior to the completion by the Company of
all payments due him under Section 4(a) and (b) of this Agreement, the Company
shall continue such payments to the Executive's beneficiary designated in
writing to the Company prior to his death (or to his estate, if the Executive
fails to make such designation). This Agreement reflects the entire agreement of
the parties with respect to its subject matter and supersedes all prior written
or oral negotiations, commitments, agreements and writings.

     10. Enforceability. If any portion or provision of this Agreement shall to
any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

     11. Waiver. No waiver of any provision hereof shall be effective unless
made in writing and signed by the waiving party. The failure of any party to
require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

     12. Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, to the
Executive at the last address the Executive has filed in writing with the
Company, or to the Company at its main office, attention of the Board of
Directors.

     13. Effect on Other Plans. An election by the Executive to resign after a
Change in Control under the provisions of this Agreement shall not be deemed a
voluntary termination of employment by the Executive for the purpose of
interpreting the provisions of any of the Company's benefit plans, programs or
policies. Nothing in this Agreement shall be construed

                                        7
<PAGE>   8

to limit the rights of the Executive under the Company's benefit plans, programs
or policies except as otherwise provided in Section 5 hereof, and except that
the Executive shall have no rights to any severance benefits under any severance
pay plan.

     14. Amendment. This Agreement may be amended or modified only by a written
instrument signed by the Executive and by a duly authorized representative of
the Company.

     15. Governing Law. This is a Massachusetts contract and shall be construed
under and be governed in all respects by the laws of the Commonwealth of
Massachusetts.

     16. Obligations of Successors. In addition to any obligations imposed by
law upon any successor to the Company, the Company will use its best efforts to
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to expressly assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform if no such succession had taken place.

     17. Confidential Information. The Executive shall never use, publish or
disclose in a manner adverse to the Company's interests, any proprietary or
confidential information relating to (a) the business, operations or properties
of the Company or any subsidiary or other affiliate of the Company, or (b) any
materials, processes, business practices, technology, know-how, research,
programs, customer lists, customer requirements or other information used in the
manufacture, sale or marketing of any of the respective products or services of
the Company or any subsidiary or other affiliate of the Company; provided,
however, that no breach or alleged breach of this Section 17 shall entitle the
Company to fail to comply fully and in a timely manner with any other provision
hereof. Nothing in this Agreement shall preclude the Company from seeking money
damages, or equitable relief by injunction or otherwise without the necessity of
proving actual damage to the Company, for any breach by the Executive hereunder.

     18. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be an original, but all of which together will
constitute one instrument binding upon the parties hereto.

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

     AGREEMENT made as of the 14th day of May, 1998, by and between Instron
Corporation, a Massachusetts corporation with its principal place of business in
Canton, Massachusetts (the "Company"), and [Name of Executive] of [Address of
Executive] (the "Executive").

     1. Purpose. The Company considers it essential to the best interests of its
stockholders to foster the continuous employment of key management personnel.
The Board of Directors of the Company (the "Board") recognizes, however, that,
as is the case with many publicly held corporations, the possibility of a Change
in Control (as defined in Section 2 hereof) exists and that such possibility,
and the uncertainty and questions which it may raise among management, may
result in the departure or distraction of management personnel to the detriment
of the Company and its stockholders. Therefore, the Board has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of members of the Company's management, including the
Executive, to their assigned duties without distraction in the face of
potentially disturbing circumstances arising from the possibility of a Change in
Control. Nothing in this Agreement shall be construed as creating an express or
implied contract of employment and, except as otherwise agreed in writing
between the Executive and the Company, the Executive shall not have any right to
be retained in the employ of the Company.

     2. Change in Control. A "Change in Control" shall be deemed to have
occurred in any one of the following events:

     (a) any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
the Securities Exchange Act of 1934 (the "Act")) becomes a "beneficial owner"
(as such term is defined in Rule 13d-3 promulgated under the Act) (other than
the Company, any trustee or other fiduciary holding securities under an employee
benefit plan of the Company, or any corporation owned, directly or indirectly,
by the stockholders of the Company in substantially the same proportions as
their ownership of stock of the Company), directly or indirectly, of securities
of the Company representing fifty percent (50%) or more of the combined voting
power of the Company's then outstanding securities;

     (b) persons who, as of March 4, 1998, constituted the Company's Board (the
"Incumbent Board") cease for any reason, including without limitation as a
result of a tender offer, proxy contest, merger or similar transaction, to
constitute at least a majority of the Board, provided that any person becoming a
director of the Company subsequent to March 4, 1998 whose election was approved
by at least a majority of the directors then comprising the Incumbent Board
shall, for purposes of this Agreement, be considered a member of the Incumbent
Board;

<PAGE>   2

     (c) the stockholders of the Company approve a merger or consolidation of
the Company with any other corporation or other entity, other than (a) a merger
or consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than 80% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (b) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
"person" (as hereinabove defined) acquires more than 50% of the combined voting
power of the Company's then outstanding securities; or

     (d) the stockholders of the Company approve a plan of complete liquidation
of the Company or an agreement for the sale or disposition by the Company of all
or substantially all of the Company's assets.

     3. Terminating Event. A "Terminating Event" shall mean any of the events
provided in this Section 3 occurring subsequent to a Change in Control as
defined in Section 2:

     (a) termination by the Company of the employment of the Executive with the
Company for any reason other than (A) a willful act of dishonesty by the
Executive with respect to any matter involving the Company or any subsidiary or
affiliate, or (B) conviction of the Executive of a crime involving moral
turpitude, or (C) the gross or willful failure by the Executive to substantially
perform the Executive's duties with the Company, or (D) the failure by the
Executive to perform his full-time duties with the Company by reason of his
death, disability or retirement; provided, however, that a Terminating Event
shall not be deemed to have occurred pursuant to this Section 3(a) solely as a
result of the Executive being an employee of any direct or indirect successor to
the business or assets of the Company, rather than continuing as an employee of
the Company following a Change in Control. For purposes of clauses (A) and (C)
of this Section 3(a), no act, or failure to act, on the Executive's part shall
be deemed "willful" unless done, or omitted to be done, by the Executive without
reasonable belief that the Executive's act, or failure to act, was in the best
interest of the Company and its subsidiaries and affiliates. For purposes of
this Agreement, "disability" shall mean the Executive's incapacity due to
physical or mental illness which has caused the Executive to be absent from the
full-time performance of his duties with the Company for a period of six (6)
consecutive months if the Company shall have given the Executive a Notice of
Termination and, within thirty (30) days after such Notice of Termination is
given, the Executive shall not have returned to the full-time performance of his
duties. For purposes of this Agreement, "retirement" shall mean termination of
the Executive's employment in accordance with the Company's retirement policy,
not including early retirement, generally applicable to its salaried employees,
as in effect immediately prior to the Change in Control, or 


                                       2
<PAGE>   3

in accordance with any retirement arrangement established with respect to the
Executive with the Executive's express written consent;

     (b) termination by the Executive of the Executive's employment with the
Company for Good Reason. Good Reason shall mean the occurrence of any of the
following events:

          (i) a substantial adverse change, not consented to by the Executive,
     in the nature or scope of the Executive's responsibilities, authorities,
     powers, functions or duties from the responsibilities, authorities, powers,
     functions or duties exercised by the Executive immediately prior to the
     Change in Control; or

          (ii) a reduction in the Executive's annual base salary as in effect on
     the date hereof or as the same may be increased from time to time except
     for across-the-board salary reductions similarly affecting all or
     substantially all management employees; or

          (iii) the relocation of the Company's offices at which the Executive
     is principally employed immediately prior to the date of a Change in
     Control to a location more than fifty (50) miles from such offices, or the
     requirement by the Company for the Executive to be based anywhere other
     than the Company's offices at such location, except for required travel on
     the Company's business to an extent substantially consistent with the
     Executive's business travel obligations immediately prior to the Change in
     Control; or

          (iv) the failure by the Company to pay to the Executive any portion of
     his compensation or to pay to the Executive any portion of an installment
     of deferred compensation under any deferred compensation program of the
     Company within fifteen (15) days of the date such compensation is due
     without prior written consent of the Executive; or

          (v) the failure by the Company to obtain an effective agreement from
     any successor to assume and agree to perform this Agreement.

     4. Severance Payment. In the event a Terminating Event occurs within
twenty-four (24) months after a Change in Control,

     (a) the Company shall pay to the Executive an amount equal to two (2) times
the "base amount" (as such term is defined in Section 280G(b)(3) of the Internal
Revenue Code of 1986, as amended (the "Code")) applicable to the Executive (the
"Base Amount"), payable in one lump-sum payment. Said amount shall be paid no
later than thirty-one (31) days following the Date of Termination (as such term
is defined in Section 8(b)); and

     (b) the Company shall pay to the Executive all reasonable legal and
arbitration fees and expenses incurred by the Executive in successfully
obtaining or enforcing any right or benefit provided by this Agreement.

                                       3
<PAGE>   4

     5A. Additional Benefits. This Section 5A shall apply solely to the extent
the sum of (i) the payments made by the Company to or for the benefit of the
Executive under this Agreement (the "Severance Payment") and (ii) the value, as
calculated in accordance with Section 280G of the Code, of the benefits and
payments received by the Executive as a result of a Change in Control under any
other agreement or plan (the "Other 280G Benefits") (the sum of such Severance
Payment and the Other 280G Benefits are referred to as the "Total Severance
Benefits"), exceed 330% of the Base Amount (the "Threshold Amount").

     (a) In the event the Total Severance Benefits exceed the Threshold Amount,
then the Executive shall be entitled to receive an additional payment (a
"Gross-Up Payment") such that the net amount retained by the Executive, after
deduction of the excise tax imposed by Section 4999 of the Code (the "Excise
Tax") on the Total Severance Benefits, any Federal, state and local income tax,
employment tax and Excise Tax upon the payment provided by this subsection, and
any interest and/or penalties assessed with respect to such Excise Tax, shall be
equal to the Total Severance Benefits.

     (b) Subject to the provisions of Section 5A(c), all determinations required
to be made under this Section 5A, including the amount of such Gross-Up Payment,
shall be made by the Company's independent accounting firm (the "Accounting
Firm") which shall provide detailed supporting calculations both to the Company
and the Executive within 15 business days of the Date of Termination, if
applicable, or at such earlier time as is reasonably requested by the Company or
the Executive. For purposes of determining the amount of the Gross-Up Payment,
the Executive shall be deemed to pay federal income taxes at the highest
marginal rate of federal income taxation applicable to individuals for the
calendar year in which the Gross-Up Payment is to be made and state and local
income taxes at the highest marginal rates of individual taxation in the state
and locality of the Executive's residence on the Date of Termination, net of the
maximum reduction in federal income taxes which could be obtained from deduction
of such state and local taxes. The Gross-Up Payment, as determined pursuant to
this Section 5A(b), shall be paid to the Executive within five days of the
receipt of the Accounting Firm's determination. Any determination by the
Accounting Firm shall be binding upon the Company and the Executive. As a result
of the uncertainty in the application of Section 4999 of the Code at the time of
the initial determination by the Accounting Firm hereunder, it is possible that
Gross-Up Payments which will not have been made by the Company should have been
made (an "Underpayment"). In the event that the Company exhausts its remedies
pursuant to Section 5A(c) and the Executive thereafter is required to make a
payment of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred, consistent with the calculations required to be
made hereunder, and any such Underpayment, and any interest and penalties
imposed on the Underpayment and required to be paid by the Executive in
connection with the proceedings 

                                       4
<PAGE>   5

described in Section 5A(c), shall be promptly paid by the Company to or for the
benefit of the Executive.

     (c) The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment by the
Company of the Gross-up Payment. Such notification shall be given as soon as
practicable but no later than 10 business days after the Executive knows of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. The Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which he
gives such notice to the Company (or such shorter period ending on the date that
any payment of taxes with respect to such claim is due). If the Company notifies
the Executive in writing prior to the expiration of such period that it desires
to contest such claim, the Executive shall:

          (i) give the Company any information reasonably requested by the
     Company relating to such claim,

          (ii) take such action in connection with contesting such claim as the
     Company shall reasonably request in writing from time to time, including,
     without limitation, accepting legal representation with respect to such
     claim by an attorney selected by the Company,

          (iii) cooperate with the Company in good faith in order effectively to
     contest such claim, and

          (iv) permit the Company to participate in any proceedings relating to
     such claim; provided, however that the Company shall bear and pay directly
     all costs and expenses (including additional interest and penalties)
     incurred in connection with such contest and shall indemnify and hold the
     Executive harmless, on an after-tax basis, for any Excise Tax or income
     tax, including interest and penalties with respect thereto, imposed as a
     result of such representation and payment of costs and expenses. Without
     limitation on the foregoing provisions of this Section 5A(c), the Company
     shall control all proceedings taken in connection with such contest and, at
     its sole option, may pursue or forego any and all administrative appeals,
     proceedings, hearings and conferences with the taxing authority in respect
     of such claim and may, at its sole option, either direct the Executive to
     pay the tax claimed and sue for a refund or contest the claim in any
     permissible manner, and the Executive agrees to prosecute such contest to a
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Company shall
     determine; provided, however, that if the Company directs the Executive to
     pay such claim and sue for a refund, the Company shall advance the amount
     of such payment to the Executive on an interest-free basis and shall
     indemnify and hold the Executive harmless, on an after-tax 

                                       5
<PAGE>   6

     basis, from any Excise Tax or income tax, including interest or penalties
     with respect thereto, imposed with respect to such advance or with respect
     to any imputed income with respect to such advance; and further provided
     that any extension of the statute of limitations relating to payment of
     taxes for the taxable year of the Executive with respect to which such
     contested amount is claimed to be due is limited solely to such contested
     amount. Furthermore, the Company's control of the contest shall be limited
     to issues with respect to which a Gross-Up Payment would be payable
     hereunder and the Executive shall be entitled to settle or contest, as the
     case may be, any other issues raised by the Internal Revenue Service or any
     other taxing authority.

     (d) If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 5A(c), the Executive becomes entitled to receive any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5A(c)) promptly pay to the Company
the amount of such refund (together with any interest paid or credited thereon
after taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5A(c), a determination is
made that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

     5B. Limitation on Benefits. This Section 5B shall apply solely to the
extent the Total Severance Benefits are less than or equal to the Threshold
Amount.

     (a) Solely in the event the Total Severance Benefits are less than or equal
to the Threshold Amount, it is the intention of the Executive and of the Company
that no payments of the Total Severance Benefits by the Company to or for the
benefit of the Executive under this Agreement or any other agreement or plan
shall be non-deductible to the Company by reason of the operation of Section
280G of the Code relating to parachute payments. Accordingly, and
notwithstanding any other provision of this Agreement or any such agreement or
plan, if by reason of the operation of said Section 280G, any such payments
exceed the amount which can be deducted by the Company, the Severance Payment
which the Executive is entitled to receive under this Agreement shall be reduced
by that amount which exceeds the maximum amount deductible by the Company under
Section 280G. To the extent that Severance Payments exceeding such maximum
deductible amount have been made to or for the benefit of the Executive, such
excess payments shall be refunded to the Company with interest thereon at the
applicable federal rate determined under Section 1274(d) of the Code, compounded
annually, or at such other rate as may be required in order that no such
payments shall be non-deductible to the Company by reason of the operation of
said Section 280G.

                                       6
<PAGE>   7

     (b) If any dispute between the Company and the Executive as to any of the
amounts to be determined under this Section 5B, or the method of calculating
such amounts, cannot be resolved by the Company and the Executive, either the
Company or the Executive, after giving three (3) days' written notice to the
other, may refer the dispute to a partner in the Boston office of a firm of
independent certified public accountants selected jointly by the Company and the
Executive. The determination of such partner as to the amount to be determined
under Section 513(a) and the method of calculating such amounts shall be final
and binding on both the Company and the Executive. The Company shall bear the
costs of any such determination if the amount determined by such partner differs
to any material degree from the final amount proposed by the Company to the
Executive before submission to such partner. If there is no such material
difference, the costs of any such determination shall be evenly divided between
the Company and the Executive.

     6. Term. This Agreement shall take effect on the date first set forth above
and shall terminate upon the earlier of (a) the termination by the Company of
the employment of the Executive because of (A) a willful act of dishonesty by
the Executive with respect to any matter involving the Company or any subsidiary
or affiliate, or (B) conviction of the Executive of a crime involving moral
turpitude, or (C) the gross or willful failure by the Executive to substantially
perform the Executive's duties with the Company, or (D) the failure by the
Executive to perform his full-time duties with the Company by reason of his
death, disability (as defined in Section 3(a)) or retirement (as defined in
Section 3(a)), (b) the resignation or termination of the Executive for any
reason prior to a Change in Control, or (c) the resignation of the Executive
after a Change in Control for any reason other than the occurrence of any of the
events enumerated in Section 3(b)(i)-(v) of this Agreement.

     7. Withholding. All payments made by the Company under this Agreement shall
be net of any tax or other amounts required to be withheld by the Company under
applicable law.

     8. Notice and Date of Termination; Disputes, Etc.

     (a) Notice of Termination. After a Change in Control and during the term of
this Agreement, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with this Section
8. For purposes of this Agreement, a "Notice of Termination" shall mean a notice
which shall indicate the specific termination provision in this Agreement relied
upon and the Date of Termination. Further, a Notice of Termination pursuant to
one or more of clauses (A) through (C) of Section 3(a) hereof is required to
include a copy of a resolution duly adopted by the affirmative vote of not less
than two-thirds (2/3) of the entire membership of the Board at a meeting of the
Board (after reasonable notice to the Executive and an opportunity for the
Executive, accompanied by the Executive's counsel, to be heard before the Board)
finding that, in the good faith opinion of the 

                                       7
<PAGE>   8

Board, the termination met the criteria set forth in one or more of clauses (A)
through (C) of Section 3(a) hereof.

     (b) Date of Termination. "Date of Termination", with respect to any
purported termination of the Executive's employment after a Change in Control
and during the term of this Agreement, shall mean (i) if the Executive's
employment is terminated for disability, thirty (30) days after Notice of
Termination is given (provided that the Executive shall not have returned to the
full-time performance of the Executive's duties during such thirty (30) day
period) and (ii) if the Executive's employment is terminated for any other
reason, the date specified in the Notice of Termination. In the case of a
termination by the Company other than a termination pursuant to one or more of
clauses (A) through (C) of Section 3(a) (which may be effective immediately),
the Date of Termination shall not be less than thirty (30) days after the Notice
of Termination is given. In the case of a termination by the Executive, the Date
of Termination shall not be less than fifteen (15) days from the date such
Notice of Termination is given. Notwithstanding Section 3(a) of this Agreement,
in the event that the Executive gives a Notice of Termination to the Company,
the Company may unilaterally accelerate the Date of Termination and such
acceleration shall not result in a Terminating Event for purposes of Section
3(a) of this Agreement.

     (c) No Mitigation. The Company agrees that, if the Executive's employment
by the Company is terminated during the term of this Agreement, the Executive is
not required to seek other employment or to attempt in any way to reduce any
amounts payable to the Executive by the Company pursuant to Section 4(a) and (b)
hereof. Further, the amount of any payment provided for in this Agreement shall
not be reduced by any compensation earned by the Executive as the result of
employment by another employer, by retirement benefits, by offset against any
amount claimed to be owed by the Executive to the Company or otherwise.

     (d) Settlement and Arbitration of Disputes. Any controversy or claim
arising out of or relating to this Agreement or the breach thereof shall be
settled exclusively by arbitration in accordance with the laws of the
Commonwealth of Massachusetts by three arbitrators, one of whom shall be
appointed by the Company, one by the Executive and the third by the first two
arbitrators. If the first two arbitrators cannot agree on the appointment of a
third arbitrator, then the third arbitrator shall be appointed by the American
Arbitration Association in the City of Boston. Such arbitration shall be
conducted in the City of Boston in accordance with the rules of the American
Arbitration Association for commercial arbitrations, except with respect to the
selection of arbitrators which shall be as provided in this Section 8(d).
Judgment upon the award rendered by the arbitrators may be entered in any court
having jurisdiction thereof.

     9. Assignment; Prior Agreements. Neither the Company nor the Executive may
make any assignment of this Agreement or any interest herein, by operation of
law or otherwise, without the prior written consent of the other party, and
without such consent any attempted transfer shall be null and void and of no
effect. This Agreement shall inure to the 

                                       8
<PAGE>   9

benefit of and be binding upon the Company and the Executive, their respective
successors, executors, administrators, heirs and permitted assigns. In the event
of the Executive's death after a Terminating Event but prior to the completion
by the Company of all payments due him under Section 4(a) and (b) of this
Agreement, the Company shall continue such payments to the Executive's
beneficiary designated in writing to the Company prior to his death (or to his
estate, if the Executive fails to make such designation).

     10. Enforceability. If any portion or provision of this Agreement shall to
any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

     11. Waiver. No waiver of any provision hereof shall be effective unless
made in writing and signed by the waiving party. The failure of any party to
require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

     12. Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, to the
Executive at the last address the Executive has filed in writing with the
Company, or to the Company at its main office, attention of the Board of
Directors.

     13. Effect on Other Plans. An election by the Executive to resign after a
Change in Control under the provisions of this Agreement shall not be deemed a
voluntary termination of employment by the Executive for the purpose of
interpreting the provisions of any of the Company's benefit plans, programs or
policies. Nothing in this Agreement shall be construed to limit the rights of
the Executive under the Company's benefit plans, programs or policies except as
otherwise provided in Section 5 hereof, and except that the Executive shall have
no rights to any severance benefits under any severance pay plan.

     14. Amendment. This Agreement may be amended or modified only by a written
instrument signed by the Executive and by a duly authorized representative of
the Company.

     15. Governing Law. This is a Massachusetts contract and shall be construed
under and be governed in all respects by the laws of the Commonwealth of
Massachusetts.

     16. Obligations of Successors. In addition to any obligations imposed by
law upon any successor to the Company, the Company will use its best efforts to
require any successor 

                                       9
<PAGE>   10

(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession had
taken place.

     17. Confidential Information. The Executive shall never use, publish or
disclose in a manner adverse to the Company's interests, any proprietary or
confidential information relating to (a) the business, operations or properties
of the Company or any subsidiary or other affiliate of the Company, or (b) any
materials, processes, business practices, technology, know-how, research,
programs, customer lists, customer requirements or other information used in the
manufacture, sale or marketing of any of the respective products or services of
the Company or any subsidiary or other affiliate of the Company; provided,
however, that no breach or alleged breach of this Section 17 shall entitle the
Company to fail to comply fully and in a timely manner with any other provision
hereof. Nothing in this Agreement shall preclude the Company from seeking money
damages, or equitable relief by injunction or otherwise without the necessity of
proving actual damage to the Company, for any breach by the Executive hereunder.

     IN WITNESS WHEREOF, this Agreement has been executed as a sealed instrument
by the Company by its duly authorized officer, and by the Executive, as of the
date first above written.
