ITEM 1. BUSINESS
 
OVERVIEW
 
  General Scanning Inc. ("General Scanning" or the "Company") was incorporated
in Massachusetts in 1968. The Company develops and manufactures a broad line
of laser systems for a wide range of applications in the automotive,
electronics, semiconductor, medical and aircraft industries. In addition, the
Company produces a line of laser subsystems and components, which are used in
the Company's own systems as well as sold in the merchant market. The Company
also designs and manufactures a line of thermal printers for medical
instrument companies, and recently introduced a new foil imprinting technology
for use in photo labs and retail photo finishing outlets. In 1997, over 85% of
the Company's revenues were derived from the sale of laser systems and
components. General Scanning sells and supports its products worldwide. In
1997, 56% of its sales were in the United States, 27% in Asia and 17% in
Europe. See Note 12 to Financial Statements for a more detailed description of
the Company's geographic operations.
 
  General Scanning manufactures laser systems for a variety of industrial
applications including: thin film resistor processing systems used in the
production of automotive sensors for airbags, anti-lock brakes, emissions
control and airflow measurement; thick film resistor processing systems used
in the manufacture of surface mount ("SMT") electronic components;
semiconductor package measurement systems for QFP (quad flat package), TSOPs
(thin small outline package) and BGAs (ball grid arrays); memory repair
processing systems used in the fabrication of high density computer memory
chips; inspection systems for solder paste and component placement on SMT
printed circuits; laser marking systems used for permanent identification of
products such as integrated circuit packages and automotive components;
component handling and sorting systems used in the integration of one or more
laser process or inspection systems; precision alignment systems used
primarily in the fabrication of aircraft composite structures; inspection and
metrology systems employing non-contact 3-D image processing used in the
manufacture of disk drives and other precise tolerance devices; micro-array
scanners for biological analysis; and laser systems and subsystems used in
film imaging. In addition, General Scanning manufactures laser subsystems and
components used by the Company and its customers in many applications
including materials processing, test and measurement, alignment, inspection,
graphics, vision systems, rapid prototyping and certain medical procedures
including dermatology and ophthalmology.
 
  The Company's core technological expertise which is employed in each of
these applications is high speed micropositioning and precise power control of
lasers, as well as 2D and 3D image processing. Designing and manufacturing the
Company's products requires specialized skills in: electronics that can
operate reliably and accurately under a wide range of environmental
conditions; electromechanical devices that can sustain high torsional
acceleration; optics and lenses that operate with a variety of laser power and
wavelength; closed-loop electronic servo systems that precisely and quickly
measure and control relative positions of mechanical components; and software
that controls laser systems and interfaces with adjunct equipment. In
addition, General Scanning maintains control of the critical production
processes which the Company believes allows it to control costs, realize
higher quality production and bring new products to market more quickly. Two
of the Company's core development and manufacturing sites, located in
Wilmington, MA and Bedford, MA, are ISO 9001 certified operations.
 
  General Scanning expands the scope and use of its core products by working
closely with leading customers to identify both value-added functionality and
new applications. The Company designs and manufactures systems and components
with the aim of providing its customers with low overall cost of ownership.
General Scanning's close relationship with its customers enables it to expand
the number of applications for its core technology and reduce the risk
inherent in new product development. The Company believes that the diversity
of applications for its products reduces the risk of dependence on the
economic conditions in any one industrial sector it serves.

BUSINESS STRATEGY
 
  The Company's strategy is to continue to apply its expertise in rapid and
high accuracy micropositioning and precise power control of laser beams and 2-
D and 3-D image processing to the development and manufacture of end-user and
OEM systems, subsystems and components for a broad range of market
applications. This strategy builds upon the Company's strengths in technology,
manufacturing and distribution.
 
  The key elements of the Company's business strategy are as follows:
 
  Leverage Core Technology. The Company is committed to developing new
products and enhancing existing products to address new applications and
evolving manufacturing requirements primarily by leveraging the Company's core
technologies for high accuracy micropositioning and precise power control of
lasers and in image processing.
 
  Customer Driven Product Development. The Company seeks to partner and work
closely with leading manufacturing companies in selected but diverse areas.
This approach allows the Company to incorporate customer feedback during the
design process, which expedites product development, thereby saving
development time and expense. The Company believes that developing a product
to meet a need identified by a market leader and potential customer decreases
the risk typically associated with new product introductions.
 
  Broad Applications in Diverse Markets. The Company currently offers products
serving broad applications in diverse markets, including laser systems for
semiconductor manufacturing, production of automotive sensors, manufacturing
of electronic components and circuits, precision alignment of manufactured
parts, permanent product marking, film imaging and biological analysis. The
Company makes subsystems and components for OEM manufacturers of equipment for
detection of in-process defects and contamination, performance of medical
diagnostic and corrective procedures, confocal microscopy, film imaging, rapid
prototyping, and medical patient vital sign recording. By addressing diverse
markets, the Company seeks to increase its product sales and reduce its
reliance on any single industry or customer. In addition, the Company's
marketing strategy is to continue to develop products based on its core
technical and manufacturing competencies for markets in which it believes it
can attain a leading position in market share.
 
  Maintain Control of Critical Production Processes. The Company's
manufacturing strategy is to identify and perform internally those
manufacturing functions which enable the Company to maintain control over
critical portions of the production process and which add value to its
products. The Company believes it achieves a number of competitive advantages
from such integration, including the ability to achieve lower cost and higher
quality, to bring new products and product enhancements quickly and reliably
to market, and to produce sophisticated component parts not readily available
from other sources.
 
  Focus on Customers' Overall Cost of Ownership. The Company designs and
manufactures systems, subsystems and components aimed at providing its
customers with low overall cost of ownership relative to competing solutions.
The Company's laser systems are intended to assist customers in achieving
higher yields, greater productivity, more efficient use of operator time and
more economical use of manufacturing space.
 
  Address Worldwide Markets. The Company markets, sells and supports its
products worldwide. The Company believes the strength of its international
sales and customer support organization is important to its continued success.
To facilitate its worldwide marketing strategy, the Company has dedicated
sales and support organizations in Japan, Hong Kong, Korea, Taiwan, Singapore,
Malaysia, Germany, England, France and Italy, in addition to eight major
locations in the United States.
 
PRODUCTS AND SERVICES
 
 Laser Systems and Components
 
  Thin Film Laser Processing Systems--The Company's laser systems are used in
the production of thin film circuits to precisely tune the performance of
linear and mixed signal devices used in a variety of applications
 
                                       2
<PAGE>
 
including automotive electronics, consumer products, personal computers,
communications products, appliances, and medical instruments. Tuning is
accomplished by adjusting various component parameters with selective laser
cuts, while the circuit is under test, thereby achieving the desired
electrical performance. For example, in automotive applications, these
precision sensor circuits are used to measure analog variables such as
acceleration, voltage, temperature and pressure, and convert them into
electronic signals suitable for computer processing and subsequent control of
vehicle performance and safety. Automotive applications include engine
control, airbag deployment, anti-lock brake control and active suspension
systems. The M310 laser system subjects the sensor to a calibrating pressure
and then the laser adjusts the sensor parameters to exacting specifications.
The Company's M310 systems combine material handling, test stimulus,
temperature control and laser trim subsystems into a single turnkey package
for tuning linear and mixed signal devices.
 
  More recently, such linear mixed signal circuits are being adopted for smart
appliances (such as camcorders and mobile GPS devices), extended life
batteries, video games, medical instruments and HVAC systems. Such mixed
signal devices were one of the fastest growing segments in the electronic
components industry during 1997. The Company's thin film resistor processing
systems range in price from approximately $300,000 to $1,000,000.
Representative customers include Analog Devices, Robert Bosch, Denso, Fuji
Denki, Burr Brown, Maxim, Motorola and Texas Instruments.
 
  Thick Film Laser Processing Systems--The Company's laser systems are used in
the production of thick film resistive components (known as chip resistors)
for surface mount ("SMT") electronic circuits. Chip resistors are
microelectronic components that replace larger axial lead resistors formerly
used in electronic circuits. Chip resistors are used in most consumer and
industrial electronic products including CD players, VCRs, TVs, camcorders and
cellular telephones. A camcorder, for example, may contain over five hundred
chip resistors. The increasing use of these devices is being driven by the
demand for enhanced functionality, reduced size, and lower cost of consumer
electronics. SMT components meet these needs by providing reduced package size
and production set-up time, and improved reliability and delivery times. The
Company's W724C laser system is an integral part of the process for
manufacturing chip resistors. By means of selected cuts, laser systems are
used to change the effective length and cross section of the electrical
conductor of each resistor element. The resistance is monitored, and the laser
action continues until the precise resistance value is obtained. The Company
believes that the size of resistors will continue to shrink and, as a result,
manufacturers will require more precise laser systems.
 
  The Company's W670 laser systems are used for processing more general
purpose hybrid thick film electronic circuits. These circuits are designed to
withstand harsh environmental uses, such as automotive ignition controls, fuel
sensors and high voltage regulation.
 
  The Company's thick film resistor processing systems range in price from
approximately $200,000 to $350,000. Representative customers include Kyocera,
Matsushita, Philips, Samsung and Vishay.
 
  Semiconductor Measurement Systems--Semiconductor measurement products are
used by customers who manufacture electronic chips and chip packages. These
customers require fully automated, high throughput systems to inspect
electronics packages. Due to the semiconductor industry's drive toward
miniaturization, components and finished packages are becoming smaller and
more fragile. A single damaged lead, bent by a few thousandths of an inch, can
cause manufacturing defects and product failures. Accordingly, semiconductor
chip manufacturers are effectively required to inspect 100% of their chip
packages.
 
  The Company's products perform inspection during fabrication of the chip (in
the "front end" of the manufacturing process) and perform inspection of final
assembled components (in the "back end"). The systems incorporate the
Company's patented three-dimensional scanning laser data acquisition
technology to provide fast, accurate measurement. The Model 890, released in
early 1997, performs front-end wafer, die and package substrate measurement
for the newly emerging high-density, matrix-based package interconnect market.
The Model 880, first introduced in 1995, performs measurement of finished
package leads or bumps without removal of the devices from their carrier
trays. All of the systems are configurable to support a variety of device and
 
                                       3
<PAGE>
 
feature types. Current prices for the base systems range from $150,000 to
$275,000. Customers include Anam/Amkor, Intel, Micron, Samsung and Texas
Instruments.
 
  Surface Mount Measurement Systems--The Company's surface mount measurement
products address another sector of the electronics industry, the manufacture
of printed circuit board assemblies. Customers for SMT measurement products
require systems which can be used for prototyping, near-process monitoring and
in-line process control. These systems can be installed near or in the circuit
board assembly line to address these needs. In the manufacture of surface-
mount electronics, solder, in paste form, is stenciled onto the circuit board
with a screen printer, and then components are placed in their respective
positions on the board by automated equipment. Critical variables in the
manufacturing process, which the Company's systems address, include the amount
of solder deposited on the board and the accurate placement of the electronic
components.
 
  The Model 8100 system was introduced in 1995 and represents the third
generation of equipment design. The Model 8100 uses the Company's patented
three-dimensional scanning laser data acquisition technology, and can inspect
either solder paste depositions or component placement accuracy. The current
base price for the Model 8100 system is approximately $200,000 to $250,000.
The strongest market segments for SMT measurement products have been in the
computer, telecommunications and automotive industries as well as in contract
manufacturers which serve those and other industries. Customers include
Celestica, Chrysler, Hewlett-Packard, Intel, Marconi and Motorola.
 
  Memory Repair Systems--Dynamic random access memory chips are critical
components in the active memory portion of computers and a broad range of
other digital electronic products. To obtain efficient yields in the
production process, each memory component is designed with redundant
circuitry. Using the Company's M325 laser system, a semiconductor manufacturer
can effectively disconnect defective or redundant circuits in a memory chip
with accurately positioned and power modulated laser pulses. This improves the
yield of usable components per treated wafer, effectively lowering the cost
per unit produced.
 
  The demand for memory, measured in megabits, has in recent years been
growing at greater than 50% per year. Approximately half to three quarters of
memory components produced are used in personal computers, with additional
demand coming from networked systems (file servers), flat panel displays,
multimedia systems and consumer electronics. Memory demand by the computer
industry is driven by both memory intensive software (Windows 95(R), graphics,
etc.) and higher speed microprocessors. As the memory capacity increases, the
feature size and spacing between the elements of the microcircuits decrease.
The industry is presently changing from 16 megabit to 64 megabit memory in
response to the demand for additional memory, space limitations to accommodate
it and manufacturing economics. The Company offers products which are
currently being used for processing memory up to and including 64 megabits.
First-pass manufacturing yields are typically low at the start of production
of a new generation of higher capacity devices. First-pass yields have
decreased to, now, less than 20% with each successive generation of memory
chips as geometries shrink and manufacturing becomes more difficult. Laser
processing is used to raise production yields to acceptable economic levels,
frequently to greater than 95%.
 
  Memory components are currently produced in batches on silicon wafers
typically measuring 6" or 8" in diameter. The industry is currently planning
for production using 12" (300 millimeter) diameter wafers. The Company
believes that its technology and systems architecture will allow it to develop
and introduce products to process the new 12" wafers. The Company's newly
introduced M325 memory processing systems range in price from approximately
$500,000 to $900,000. Representative customers include Cypress Semiconductor,
Dominion Semiconductor, IBM, Mitsubishi and Toshiba.
 
  Permanent Marking Systems--The Company's moving spot laser marking systems
are used to apply permanent alphanumeric, graphic and bar-code identification
directly onto electronic components, industrial products and packaging
materials. Laser marking systems remove precise amounts of material from, or
modify the surface of, an object being marked by exact control of the laser
beam as it moves along a prescribed path.
 
                                       4
<PAGE>
 
Such systems are gaining acceptance over a broad range of markets, replacing
older technologies such as inkjet, mechanical imprinting, chemical etching and
ink stamping. This change is being driven by the need for permanent marking
and for marking systems which can be interfaced with computers, and by
environmental acceptance. Industry has recently begun to require product
traceability for years after the date of manufacture. At present, inkjet and
ink stamping do not provide this permanence, while laser marking does. Also,
the laser marking process does not involve the use of environmentally
hazardous solvents.
 
  As an example of this application, the Company's HM1500 laser system is used
to mark integrated circuit ("IC") packages. The plastic or ceramic package
surrounding an IC must be marked without penetration of its thin wall in order
to avoid damaging the expensive circuits it protects. This process requires a
high degree of precision. Laser marking for this application is gaining
widespread usage. The Company's laser systems are also used in other
applications including the marking of automotive parts, electrical components,
tools, medical implants, as well as in the decorative marking of consumer
items. During 1996, the Company replaced its current product offerings with
the 1000 Series products which offered significant advantages in terms of
higher power, larger marking fields, faster marking speeds and higher
precision. In 1997, the Company introduced a diode-pumped laser marker, with a
full 8,760 hour warranty on the laser, which requires no external cooling or
three-phase power. The FM3500-4 laser marking system, also introduced in mid
year, multiplexes a high power laser beam into four completely independent
marking heads that can be remotely located up to 100 feet away from the laser
by fiber optic cable. The Company's laser marking systems range in price from
approximately $50,000 to $225,000. Representative customers include Harris,
Hewlett-Packard, Motorola, SGS Thompson, Texas Instruments and Toshiba.
 
  Components Handling Systems--The Company designs, manufactures and, then,
integrates electronic components handling systems for laser marking, lead
inspection, parts sorting and parts packaging. This capability was added in
late 1997 through the acquisition of Reel-Tech, Inc. Products include in-tray
laser marking, tube-to-tube laser marking, tape and reel systems, media
transfer systems and integrated multi-process systems. These systems can
handle a wide variety of component package configurations. This capability
enables General Scanning to more effectively serve its customers by meeting
the emerging trend to more closely integrate multiple processes and,
therefore, increase manufacturing productivity. The Company's component
handler systems sell in the price range of approximately $125,000 to $400,000.
Representative customers include Micron, Motorola and Samsung.
 
  Precision Alignment Systems--The Company's precision alignment systems
interface with computer assisted design and manufacturing ("CAD/CAM") software
to assist in the precision alignment of parts during manufacturing assembly
processes. The principal use to date has been in the precision alignment of
composite materials for the aircraft industry. Composite materials are
important elements in the fabrication of critical structures for aircraft,
such as jet engine cowlings, cargo and nose wheel doors, and control surfaces
of the wings and vertical stabilizer, as well as for major components in jet
engines, helicopters, communication satellites and rockets. The Company's
systems project a precise image generated from existing CAD/CAM data to guide
the assembly operations personnel in the proper placement and order of layers
of composite materials. The Company's OLT4000 precision alignment systems
allow aircraft manufacturers to eliminate mechanical alignment templates,
minimize costs from engineering changes, and reduce operator learning time and
assembly labor requirements. The Company is exploring the applications of
these systems in other markets. The Company's precision alignment systems sell
in the range from approximately $50,000 to $250,000. Representative customers
include Bell Helicopter, Boeing, CFAN, Daimler-Benz Aerospace, Hughes Aircraft
and Northrop Grumman.
 
  Metrology Systems--The Company's metrology products are automated, non-
contact dimensional coordinate measurement systems which provide major
electronics, telecommunications, and computer manufacturers with the ability
to perform micron accurate measurements of component parts and assemblies
produced throughout their manufacturing processes. These systems utilize
combinations of CCD video camera, image processing, and various laser sensor
technologies to acquire part measurement data. The metrology products are
primarily sold to manufacturers of disk drives, semiconductor packages,
printed circuit boards, and
 
                                       5

their associated micro-electronic components. During 1997, the Company
replaced one of its core product offerings with a new Voyager platform
featuring advances in illumination and autofocus technology, complemented by
easy-to-use graphical user interface to facilitate measurement and
programming. Current prices range from $55,000 to $150,000. Representative
customers include Applied Magnetics, Cummins Engine, IBM, Intel, K. R.
Precision and Seagate Technology.
 
  Film Imaging Systems--The application of lasers for imaging directly onto
film has progressed steadily over the past decade to the point where it has
become the technology of choice in two major markets: medical diagnostics and
graphics. Both applications demand precise micropositioning for pixel
placement and adjustable contrast range. Medical diagnostics often involve
images of the human anatomy derived from computer assisted tomography ("CAT"),
magnetic resonance imaging ("MRI") or nuclear medicine systems. Such images
are usually presented on photographic film for viewing by a radiologist. The
Company's laser imaging subsystems are used to produce images of adjustable
gray-level contrast and high resolution for enhanced medical diagnostic
purposes. The Company's laser imaging equipment, using data sets from CAT, MRI
or nuclear medicine equipment, creates a film image by moving a laser beam
across the width of the film, and modulating it to produce the correct gray
scale level for each picture element, or pixel. When the width of the film has
been scanned, the next line is scanned in sequence. The process is continued
until the entire image is exposed.
 
  In late 1997, General Scanning introduced a film duplicating system which
duplicates 8 x 10 and 14 x 17 films from existing X-ray, CAT and MRI
electronic films. Initially, the system will directly interface with wet and
dry laser imaging systems including Imation's DryView 8700 Laser Imaging
System. The Company intends to expand this digitizing equipment with future
applications in teleradiology and PACS (picture archiving and communication
systems).
 
  The Company also sells a modified version of its film imaging subsystem to
write directly onto a film plate for graphic printing.
 
  The Company's laser imaging systems and subsystems sell in the range from
approximately $1,500 to $20,000. Representative customers include A.B. Dick,
Agfa and Imation.
 
  Large format systems--In 1997, the Company commenced development of an
innovative laser patterning system for use in the manufacture of flat panel
displays ("FPD"). The development, alpha and beta phases of this project are
funded by two multinational companies with an interest in the FPD industry.
FPDs are compact, lightweight, low power alternatives to the traditional
picture tube used in televisions and computer monitors. A typical FPD is
composed of a thin layer of liquid crystal sandwiched between two sheets of
glass, with a variety of layers of material patterned onto the glass surfaces.
The rapidly growing FPD market has been driven by the growth in "laptop"
portable computers and is projected to grow from $10.8 billion in 1995 to
$23.7 billion in 2002 (Stanford Resources). To reduce manufacturing costs per
FPD, the industry is moving to large (up to 800mm x 800mm) glass substrates,
capable of simultaneously fabricating six to nine FPDs per substrate, and to
new techniques for one or more of the manufacturing steps. The product under
development will exploit General Scanning's expertise in the precision
pointing, shaping and control of laser beams to precision patterns, this time
over a large field of view when compared to the Company's current
applications.
 
  Biological scanners--The Company recently introduced a laser-based
fluorescence imaging system for use in the measurement of gene expression.
Identification and quantification of the expression level of different genes
under varying conditions provide researchers with a rough functional analysis
of genomic sequence information, which could lead to potential drug targets.
Similarly, gene expression analysis can be used for diagnostic purposes. Some
scientists believe that pharmacogenomics (the discipline of identifying genes
responsible for different reactions to drugs) could be the quickest route to
improving the therapeutic specificity of drugs. Several biotechnology
companies are active in the development of molecular array technology and
fluorescently labeled ligands. The ScanArray(TM) 3000 Biochip Analysis System
measures the fluorescent intensity at each DNA grid spot facilitating, at high
speed, the analysis of the expression level of a particular gene. The system
is offered for
 
                                       6
<PAGE>
 
sale to end users in research and, on an OEM basis, for resale by those
companies active in biochemistry and microchip technology.
 
  Components--The Company develops, produces and sells optical scanners and
scanner subsystems which include optics, software and control systems. These
are used by the Company and its customers in a variety of applications
including materials processing, test and measurement, alignment, inspection,
displays, graphics, vision, rapid prototyping, and medical applications
including dermatology and ophthalmology. The Company intends to continue to
work with its customers to develop new components and subsystems based upon
its optical scanning technology. The Company sells its scanners in a range
from approximately $100 to $4,000 and its subsystems in a range from
approximately $2,000 to $30,000. Representative customers include Eastman
Kodak, Lumonics, Nikon, Perceptron and Texas Instruments.
 
 Thermal Printing Products
 
  The Company develops, produces and sells a variety of thermal printers which
are designed for use with defibrillators, patient care monitors, cardiac
pacemaker programmers, and other medical applications. Thermal printers are
used to provide a permanent record of a patient's condition during critical
medical care.
 
  The Company's thermal printers generate signal traces, grids and real time
annotation on heat sensitive paper. Paper widths ranging from 48 to 216
millimeters are moved at speeds that can be remotely selected in the range
from 1 millimeter per hour to 125 millimeters per second, and have a
resolution of 8 x 32 dots per millimeter. The text and graphics are generated
by selectively and instantaneously modulating the temperature of small
(approximately 0.105 x 0.175 millimeters) elements of a print head across the
width of the chart. The heated elements create dots on thermal sensitive
paper. By repeated action under the control of an on-board microprocessor, the
desired graphic output can be produced.
 
  The Company works closely with its OEM customers to develop and produce
thermal printers which are incorporated into its customers' products. Typical
customized features of thermal printers offered by the Company include:
package and size dimensions dictated by the customer's end products; speed and
accuracy of chart transport; print resolution; number of fonts; and number of
data channels. Medical uses for the Company's thermal printers require high
reliability, since they are often used in emergency medical equipment which
must be rugged and lightweight. The Company believes that its ability to work
rapidly and efficiently with its customers provides an important benefit to
such customers. Approximately, 66,000 thermal printers were shipped during
1997. The Company's thermal printers sell in a range from approximately $200
to $3,000. Representative customers include Datascope, Marquette, Medtronic,
Physio-Control, Solectron, Spacelabs Medical and Zoll Medical.
 
  In 1997, the Company introduced a new foil imprinting technology, initially
for use in photo labs and in retail photo finishing locations for
personalization of greeting cards. The new process can replace time-consuming
litho techniques, as well as film, metal dies, type and plates typically
required by current foil stamping processes. Qualex, Inc., a subsidiary of
Eastman Kodak, is the Company's initial customer for this new application.
This technology may be applied to other materials in graphics art.

CUSTOMERS
 
  The Company has over 1,000 customers. During 1997, no single customer
accounted for more than 5% of total sales. General Scanning's ten most
significant customers in terms of sales in 1997, listed alphabetically, were:
Analog Devices, Boeing, Denso, IBM, Imation, Intel, Maxim, Micron, Physio-
Control and Texas Instruments.
 
SALES, MARKETING AND CUSTOMER SUPPORT
 
  The Company believes that its marketing, sales and customer support
organizations are important to its long-term growth and give the Company the
ability to respond rapidly to the needs of its customers. The Company has
marketing managers for each major product line who have worldwide
responsibility for determining product strategy based on knowledge of the
industry, customer requirements and product performance. These marketing
managers have direct contact with customers and support the field sales and
service personnel. The Company believes that its business may be subject to
seasonal fluctuations due to capital expenditure approval cycles of its
customers.
 
  The Company sells and supports its products worldwide through its own direct
sales and customer service organization. This domestic and international sales
network is augmented by selected independent sales representatives for end-
user laser systems, due to the geographical dispersion of customers for such
products. Field offices have been located in close proximity to key customers
to help achieve short response time. In the United States, the Company
provides marketing support at its locations in Watertown, Wilmington,
Arlington and Bedford, Massachusetts, Indianapolis, Indiana, Simi Valley and
Santa Clara, California and in Ann Arbor, Michigan. In Europe, the Company
distributes its products through its direct sales offices located in Germany,
the United Kingdom, Italy and France. The Company distributes its products in
Japan through its offices in Tokyo and Osaka. Throughout the remainder of
Asia, the Company distributes through its offices in Hong Kong, Korea,
Singapore, Malaysia and Taiwan.
 
  The Company provides customer support in the form of applications
engineering, repair services and spare parts inventory through its offices in
Massachusetts, Michigan, Indiana, California, France, Germany, Italy, the
United Kingdom, Hong Kong, Japan, Korea, Singapore, Malaysia and Taiwan.
Engineering and field support personnel provide telephone support or are
dispatched to customer locations. Additionally, the Company's offices
generally have certain models of the Company's laser systems which are used
for demonstration purposes and for applications engineering. From time to
time, at the request of a customer, the Company will install a laser system at
the customer's manufacturing site to establish manufacturing process and
demonstrate product performance as part of the selling process prior to
receipt of an order. The typical purchase of a laser system includes
installation, on-site customer support and applications engineering.
 
RESEARCH AND DEVELOPMENT
 
  The Company devotes significant resources to development programs directed
at creating new products and product enhancements, as well as developing new
applications for existing products. All of the markets served by the Company
are characterized by rapid technological change and product innovation. The
Company believes that continued timely development of new products and product
enhancements to serve both existing and new markets is necessary to remain
competitive.
 
  The Company maintains significant expertise in the following core
technologies:
 
  Mechanics: design of mechanisms with high rigidity and low moving mass; use
of materials at high stress levels; techniques for precise assembly and
vibration isolation of bearings, lasers and lenses.
 
  Optics: design of laser quality lenses with variable depth of field or large
numerical aperture; design of mirrors of high dynamic rigidity; selection of
wavelength-specific mirror and lens coatings; specification and adjustment of
lasers; and interaction of lasers with materials.
 
 
                                       9
<PAGE>
 
  Magnetics: design and use of rare-earth magnets; heat treatment of specialty
magnetic alloys; design and heat dissipation of compact electrical drive
coils.
 
  Electronics: design of wide bandwidth power amplifiers and high signal-to-
noise ratio and low thermal drift signal detection circuits; design and
manufacture of analog servo controllers with low electromagnetic interference
(EMI) circuitry.
 
  Software: development of high-speed computing algorithms for real-time
control of servo mechanisms; handling of data transmitted according to
customer-specific protocols; design of operator-friendly computer/systems
interfaces.
 
  Systems Design: integration of mechanisms, optics, lasers, laser electro-
optics, power supplies, electronics, communications interfaces and software.
 
  The Company's personnel work closely with customers, frequently at the
customers' facilities, to develop complete process solutions that often
involve new or extended application of the Company's existing products. This
close cooperation leads to new products being developed for a ready customer.
 
  For the years ended December 31, 1997, 1996 and 1995, the Company's research
and development expenditures were approximately $22.3 million (excluding a
one-time expense relating to acquired in-process research and development
associated with the acquisition of Reel-Tech), $18.4 million and $17.1
million, respectively. These amounts were approximately 12%, 12% and 14% of
sales in the respective periods. As of December 31, 1997, the Company had 206
people engaged in research and product development activities. Because the
Company believes that the development of new products is vital to its
continued success, the Company expects significant expenditures to continue on
research and development activities.
 
  Approximately one-half of sales during 1997 were from products introduced
during the current and previous two years.
 
MANUFACTURING
 
  The Company's manufacturing strategy is to identify and perform internally
those manufacturing functions which enable the Company to maintain control
over critical portions of the production process and which add value to its
products. The Company believes it achieves a number of competitive advantages
from such integration, including the ability to achieve lower costs and higher
quality, the ability to bring new products and product enhancements quickly
and reliably to market, and the ability to produce sophisticated component
parts not available from other sources.
 
  The Company's manufacturing is conducted at four facilities located near
Boston, Massachusetts and in Indianapolis, Indiana and Simi Valley,
California. Each of the Company's manufacturing facilities has co-located
manufacturing, manufacturing engineering, marketing and product design
personnel. The Company believes, based on its experience, that this
organizational proximity greatly accelerates development and entry into
production of new products and aids economical manufacturing. The Company's
thermal printers and many of its laser systems are manufactured under ISO 9001
certification.
 
  The Company has fully integrated manufacturing operations in key strategic
elements, such as state-of-the-art metals and plastics fabrication, surface
mount (SMT) printed circuit board fabrication and testing, and extensive in-
process and final product testing capabilities. The Company believes it gains
competitive advantages in its capability to produce high quality, short-run
parts and assemblies in a just-in-time environment which reduces delivery
times to customers.
 
  Certain of the components and materials included in the Company's laser
systems and optical products are currently obtained from single source
suppliers. The Company currently obtains a component for one of its laser
systems products from a single source. The Company currently maintains a six
month inventory of this component and plans to increase this over the next
year. The Company has explored the possibility of producing
 
                                      10
<PAGE>
 
this component internally, and in the event of a disruption in the outside
supply of this component, the Company believes that it could commence
production internally within twelve months.
 
  The Company is subject to a variety of governmental regulations related to
the discharge or disposal of toxic, volatile, or otherwise hazardous chemicals
used on the Company's premises. The Company believes that it is in material
compliance with these regulations and that it has obtained all necessary
environmental permits to conduct its business. Nevertheless, current or future
regulations could require the Company to purchase expensive equipment or to
incur other substantial expenses to comply with environmental regulations. Any
failure by the Company to control the use of, or adequately restrict the
discharge or disposal of, hazardous substances could subject the Company to
future liabilities, result in fines being imposed on the Company, or result in
the suspension of production or cessation of the Company's manufacturing
operations in one or more locations.
 
WORKING CAPITAL REQUIREMENTS
 
  The Company manufactures and sells a variety of laser systems, subsystems
and components, as well as a line of thermal printers. The Company maintains
levels of inventory at various states of assembly in order to be responsive to
customers' requirements.
 
BACKLOG
 
  The Company defines backlog as written purchase orders or other contractual
agreements for products for which the customer has requested delivery within
the next twelve months. Backlog was approximately $44 million on December 31,
1997 compared to $36 million on December 31, 1996.
 
COMPETITION
 
  The markets for the Company's products are highly competitive. The Company
is subject to substantial competition from both established competitors and
potential new market entrants. Significant competitive factors include:
product functionality, performance, size, flexibility, cost, market presence,
customer satisfaction, customer support capabilities and breadth of product
line. The Company believes that it competes favorably on the basis of each of
these factors.
 
  Competition in the development, manufacture and sale of laser systems is
concentrated in certain segments and fragmented in others. To the Company's
knowledge, the automotive sensor manufacturing market in which the Company's
thin film processing systems are used has no other competitors. The markets
for the thick film hybrid circuit processing systems in which the Company
competes have several other manufacturers. The Company is aware of three
competitors in vision systems for solder paste and component placement
inspection. In systems for electronic component lead inspection, the Company
competes primarily with Robotic Vision Systems. The Company competes primarily
with Electro Scientific Industries, which has the major market share, in laser
systems for memory fabrication. The Company is aware of laser marking systems
produced by many other manufacturers which compete with the Company's laser
marking equipment. There are several competitors in the field of component
handling systems. To the Company's knowledge, in the precision alignment
market for the aircraft industry, the Company has one competitor. There are
several competitors in the field of general purpose, non-contact metrology in
which the Company competes.
 
  The Company knows of at least five other manufacturers of subsystems for the
film imaging systems and subsystems market.
 
  In the optical scanner subsystem and components markets, the Company knows
of two other manufacturers. Additionally, there exist two alternate
technologies, rotating polygons and XY-moving tables, to the galvonometric
scanning technology used by the Company, which compete for certain segments of
the markets served by the Company's products.
 
                                      11
<PAGE>
 
  Thermal printing for the medical equipment market has fragmented
competition, mostly from vertically integrated equipment manufacturers.
 
  The Company expects its competitors to continue to improve the design and
performance of their products. There can be no assurance that the Company's
competitors will not develop enhancements to, or future generations of,
competitive products that will offer superior price or performance features,
or that new processes or technologies will not emerge that render the
Company's products less competitive or obsolete. As a result of the
substantial investment required by a customer to integrate capital equipment
into a production line, or to integrate components and subsystems into a
product design, the Company believes that once a customer has selected certain
capital equipment, or certain components or subsystems from a particular
vendor, the customer generally relies upon that vendor to provide equipment
for the specific production line or product application and may seek to rely
upon that vendor to meet other capital equipment, or component or subsystem
requirements. Accordingly, the Company may be at a competitive disadvantage
with respect to a particular customer if that customer utilizes a competitor's
manufacturing equipment or components. Increased competitive pressure could
lead to lower prices for the Company's products, thereby adversely affecting
the Company's business and results of operations. There can be no assurance
that the Company will be able to compete successfully in the future.
 
PATENTS AND INTELLECTUAL PROPERTY
 
  The Company believes that the success of its business depends more on the
technical competence and creativity of its employees than on patents,
trademarks and copyrights. Nevertheless, the Company has a policy of seeking
patents, when appropriate, on inventions concerning new products and
improvements as part of its ongoing research, development and manufacturing
activities.
 
  Although the Company has been granted, has filed applications for and has
been licensed under a number of patents in the United States and foreign
countries, there can be no assurance as to the degree of protection offered by
these patents or as to the likelihood that patents will be issued for pending
applications.
 
  Competitors in the United States and foreign countries, many of which have
substantially greater resources and have made substantial investments in
competing technologies, may have applied for or obtained, or may in the future
apply for and obtain, patents that will prevent, limit or interfere with the
Company's ability to make and sell some of its products. Although the Company
believes that its products do not infringe the patents or other proprietary
rights of third parties, there can be no assurance that other third parties
will not assert infringement claims against the Company or that such claims
will not be successful. (See Item 3, Legal Proceedings.)
 
  The Company also relies upon trade secret protection for its confidential
and proprietary information. The Company routinely enters into confidentiality
agreements with its employees and consultants. There can be no assurance,
however, that these agreements will provide meaningful protection of the
Company's trade secrets, know-how or other proprietary information in the
event of any unauthorized use, misappropriation or disclosure of such trade
secrets, know-how or other proprietary information.
 
EMPLOYEES
 
  As of December 31, 1997, the Company had 915 full-time employees worldwide,
including 396 in manufacturing, 226 in marketing, sales and field service, 206
in research and development, and 87 in general administration. Approximately
108 employees, mostly foreign nationals, reside and work outside of the
United States, primarily in marketing, sales and support. In addition, the
Company periodically engages contract employees principally in new product
development and manufacturing operations. None of the Company's employees is
represented by a labor union, and the Company has never experienced a work
stoppage or strike. The Company considers its employee relations to be good.

space will be available as needed.
 
ITEM 3. LEGAL PROCEEDINGS
 
  View Engineering v. Robotic Vision Systems, Inc. USDC Case No. 95-1882. On
or about March 24, 1995, View Engineering, Inc. ("View") filed a complaint
against Robotic Vision Systems, Inc. ("RVSI") seeking declaratory relief that
(i) U.S. Patent No. 4,328,147 (" '147") held by RVSI was invalid and (ii) View
had not infringed this patent. RVSI counterclaimed against View for alleged
trade libel and patent infringement on the "147 patent and on seven additional
patents, seeking a judgment that View had infringed upon one or more claims of
each of the eight patents. After View challenged the merits of RVSI's case,
RVSI dropped its infringement claims involving five of the eight patents and
did not pursue the claim of trade libel. In June, 1996, the Federal District
Court granted View a summary judgment on non-infringement with respect to the
three remaining patents and granted, in part, its motion for reimbursement of
attorneys' fees under Rule 11. The summary judgment and the Rule 11 sanctions
were appealed by RVSI. In July 1997, the summary judgment in favor of View was
upheld and affirmed by the United States Court of Appeals for the Federal
Circuit. The Rule 11 sanctions were remanded back to the District Court to
determine the amount of fees due to View.
 
  Robotic Vision Systems, Inc. v. View Engineering, Inc. USDC Case No. 95-
7441. On or about October 31, 1995, RVSI filed a complaint for patent
infringement against View alleging infringement of U.S. Patent No. 5,463,227
and seeking damages allegedly caused by View's infringement. RVSI's requests
for a temporary restraining order and a preliminary injunction were denied. In
March 1996, View obtained a summary judgment
 
                                      13
<PAGE>
 
on the first of RVSI's claims; and RVSI has dismissed the other claims. RVSI
appealed the summary judgment. In April 1997, the United States Court of
Appeals for the Federal Circuit returned the issue to the District Court for
further discovery. A trial date has been set for August 3, 1998.
 
  Robotic Vision Systems, Inc. v. View Engineering Inc. USDC Case No. 96-
2288. On or about April 1, 1996, RVSI filed a complaint for patent
infringement against View alleging infringement of U.S. Patent No. 5,465,152.
During 1997, View was denied its motion for summary judgment for
noninfringement and for invalidity. A trial commenced in December 1997 and
concluded in January 1998. A briefing schedule has been set, and final
arguments are scheduled for March 30, 1998.
 
  Robotic Vision Systems, Inc. v. General Scanning Inc. USDC Case No. 96-
3884. On or about August 5, 1996, RVSI filed an action claiming that the
Company improperly obtained proprietary information from RVSI for the purpose
of acquiring View and thwarting RVSI's attempts to acquire View. RVSI is
seeking compensatory and punitive damages in an unspecified amount. In
September 1997, the United States District Court for the Eastern District of
New York, pursuant to a motion for summary judgment filed by General Scanning,
dismissed four of RVSI's six claims. In January 1998, the District Court,
responding to a motion by RVSI, readmitted one of the claims originally
dismissed in the summary judgment. A trial is scheduled for May 4, 1998.
 
  Electro Scientific Industries, Inc. v. General Scanning Inc. USDC Case No.
C-96-04628. On or about December 26, 1996, Electro Scientific Industries, Inc.
("Electro Scientific") filed a complaint for patent infringement against the
Company alleging infringement of U.S. Patent Nos. 5,265,114 and 5,473,624.
Electro Scientific is seeking temporary and permanent restraining orders,
compensatory and punitive damages in an unspecified amount, and attorneys'
fees, costs and disbursements. The Company has filed an answer and
counterclaim to this complaint. In November 1997, the Company filed a motion
for summary judgment on the grounds that the patents are invalid. A hearing is
scheduled for February 24, 1998.
 
  General Scanning Inc. v. Voxel Pursuant to the dispute resolution provision
of a development agreement between Voxel and the Company, General Scanning is
seeking through binding arbitration recovery of monies for work performed as
well as lost profits on future production. Voxel counterclaimed seeking
recovery of lost profits. The arbitration hearing was concluded in January
1998. Following post trial submissions, a decision is expected in the spring
of 1998.
 
  The Company believes that RVSI's, Electro Scientific's and Voxel's claims in
each of the above actions are without merit and the Company is vigorously
defending these precedings. However, if RVSI, Electro Scientific or Voxel
prevails on one or more of its claims, there could be a material adverse
effect on the Company's business, financial condition or operating results.
 
  The Company is routinely involved in litigation incidental to its business,
although the Company is not aware of any other pending litigation which, if
adversely determined, could materially and adversely affect its business.
 
  ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  No matters were submitted to a vote of the Company's security holders during
the last quarter of the year ended December 31, 1997.

pooling of interests for accounting purposes and, accordingly, the financial
statements for the years 1993, 1994 and 1995 were retroactively restated to
include the accounts of View.
 
  On November 28, 1997 the Company acquired the assets of Reel-Tech, Inc. in a
transaction that was accounted for as a purchase. Accordingly, the operations
of Reel-Tech, Inc. have been included in the consolidated financial statements

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS
 
OVERVIEW
 
  General Scanning is a leading manufacturer of laser systems and components
and thermal printers. In 1997, 1996 and 1995, approximately 85%, 84%, and 82%,
respectively, of the Company's revenues were derived from sales of laser
systems and components and the balance was derived from sales of thermal
printers. Sales of laser systems and components in 1997 and in 1996 grew
approximately 17% and 28%, respectively, over sales for this segment in the
comparable prior periods. Thermal printers sales in 1997 and 1996 grew
approximately 9% and 8%, respectively, over the comparable prior periods.
 
  In November 1997, the Company acquired Reel-Tech, Inc. ("Reel-Tech"), a
wholly-owned subsidiary of Data I/O Corporation. The transaction was
structured as a purchase of substantially all the assets and the business of
Reel-Tech and its subsidiary in Singapore and is being accounted for as a
purchase. The operations of Reel-Tech have been included in the consolidated
financial statements from the date of acquisition and are not material to
comparative prior periods. The purchase price of $14.4 million includes $0.7
million of tangible net assets, $10.6 million of acquired in-process research
and development which was recorded as a charge to operations on the date of
acquisition and $3.1 million of goodwill. Reel-Tech is an integrator of
electronics components handling systems for marking, inspection, sorting and
packaging.
 
  In August 1996, the Company acquired View Engineering, Inc. by issuing
1,437,060 shares of General Scanning Common Stock. The transaction was
recorded as a pooling of interests for accounting purposes. Accordingly, the
consolidated financial statements include the accounts of View for all periods
presented. View employs laser image processing technology to serve
applications requiring precision inspection, measurement and process control
in several industries.
 
  The Company sells its laser systems primarily to manufacturers of products
containing advanced electronic components and circuitry. In addition, the
Company produces a line of laser subsystems and components which are used in
the Company's own systems, as well as sold to other manufacturers of laser
systems. The Company's laser systems sales have been, and are expected to
continue to be, dependent upon its customers' capital expenditures which are
in turn affected by cycles in the markets served by those customers. The
Company's strategy is to expand applications for its products into different
and varied markets in order to limit its dependency on any one market; but it
may not always be successful in doing so. The Company also sells thermal
printers to manufacturers of medical equipment for patient care monitoring.
 
  Product prices have remained relatively stable during the periods covered by
this discussion, and price fluctuations did not have a material effect on
reported gross profit. A significant portion of sales are made in foreign
currencies. Fluctuations in currency exchange rates, particularly in the
Japanese yen and European currencies as compared to the U.S. dollar, can
impact the Company's sales and expenses, which are reported in U.S. dollars.
 
  In September 1995, General Scanning raised a net $27.7 million through its
initial public offering of 2,585,000 shares of Common Stock including over-
allotments.
 
  The Company has begun to assess issues relating to changes in software and
hardware that may be required in the year 2000. Based on its review to date,
any costs relating to the year 2000 issue are expected to be immaterial.

RESULTS OF OPERATIONS
 
  Sales. Total sales increased to $181.5 million in 1997 from $156.5 million
in 1996 and $126.3 million in 1995. Sales of laser systems and components
increased primarily due to increased unit volume of end-user systems,
primarily reflecting growth in demand for the Company's products used in
semiconductor production and electronics manufacturing. Secondarily, sales in
1997 increased due to funding by two multinational companies for development
of a laser patterning system for use in the manufacture of flat panel
displays. The increases in the sales of thermal printers were primarily due to
increased unit volume of thermal printers and to the introduction of a new
product in the fourth quarter of 1997. International sales, as a percentage of
total sales, were 44% in 1997, 41% in 1996 and 47% in 1995.
 
  Gross Profit. Total gross profit was $86.7 million, or 47.8% of sales, in
1997, $71.7 million, or 45.8% of sales, in 1996 and $57.9 million, or 45.9% of
sales, in 1995. Laser systems and components gross profit as a percentage of
sales was 48.3%, 46.1% and 46.3% for the years 1997, 1996 and 1995,
respectively. The improvement in the laser systems and components gross profit
in 1997 was due to 1) improved absorption of labor and manufacturing overhead
over increased production volume, and 2) a reduction in material costs due to
changes in product mix and cost reductions. Thermal printers gross profit as a
percentage of sales was 44.6% in 1997, 44.0% in 1996 and 43.9% in 1995.
 
                                      19

  Research and Product Development. Research and product development expenses
increased 21% to $22.3 million in 1997 (excluding a one-time expense relating
to acquired in-process research and development associated with the
acquisition of Reel-Tech) from $18.4 million in 1996 and $17.1 million in
1995. This increase in research and product development expenses was primarily
due to the addition of personnel and related costs to support the development
of new laser systems and components. Research and product development expenses
as a percentage of sales have ranged between approximately 12% to 13% over the
past three years. Because the Company believe that the development of new
products is vital to its continued success, the Company expects to maintain
similar levels of research and development expenses as a percentage of sales
over the long term.
 
  Selling, General and Administrative. Selling, general and administrative
expenses were $46.2 million in 1997, $39.5 million in 1996 and $33.1 million
in 1995. These increases in selling, general and administrative expenses were
primarily due to the addition of sales and marketing personnel and related
costs and to additional sales commission expense incurred in supporting
increased sales. Additionally, in 1997 legal costs increased as a result of
defending various legal proceedings, as discussed in Item 3. to this Form 10-
K. Selling, general and administrative expenses as a percentage of sales have
ranged between approximately 25% to 26% over the past three years.
 
  Acquired in-process research and development. Acquired in-process research
and development expense in 1997 of $10.6 million results from an independent
appraisal of Reel-Tech's intangible assets acquired.
 
  Interest. Net interest income was $464 thousand in 1997 compared to $272
thousand in 1996 and net expense of $682 thousand in 1995. These changes
primarily reflect interest earned on cash raised in the Company's initial
public offering in September 1995 and the repayment of View's revolving credit
debt subsequent to View's acquisition by the Company in August 1996.
 
  Foreign Exchange. Foreign exchange transactions resulted in a loss of $507
thousand in 1997 and $159 thousand in 1996 as compared to a gain of $331
thousand in 1995. The losses in 1997 and 1996 were due primarily to a
weakening of the Japanese yen and major European currencies compared to the
U.S. dollar at a time when the Company's net receivables denominated in these
currencies were not fully hedged.
 
  Income Tax. The effective income tax rate for the Company was 33% in 1997,
45% in 1996 and 38% in 1995, compared to a United States Federal tax rate of
34%. The Company's effective tax rate for each year was benefited by research
and development credits and by deductions associated with the Company's
foreign sales corporation. The Company's effective rate for each year was
increased by higher tax rates in many of the countries where the Company
operates and by state income taxes. The high 1996 rate was the result of (1) a
portion of merger expenses not being tax deductible and (2) losses incurred at
View prior to the effective date of the merger that could not be used to
offset General Scanning's profit for tax purposes. The 1995 rate reflects
increased profits in the Company's foreign operations. The Company has
provided a valuation allowance against View's net operating loss carryforwards
and tax credits due to the uncertainty of their realizability as a result of
limitations on their utilization in accordance with certain tax laws and
regulations.
 
  Net Income. Net income was $5.1 million in 1997, $6.6 million in 1996 and
$4.6 million in 1995. The decrease in net income in 1997 from 1996 was due to
the $10.6 million acquired in-process research and development expense
associated with the acquisition of Reel-Tech. The increase in net income in
1996 over 1995, despite one-time merger expenses and an increase in the
effective tax rate associated with the acquisition of View, was primarily due
to increased sales and a leveraging of operating expenses which grew at a
lower rate than did the increase in sales.
 
  Summary. The Company has experienced, and may continue to experience,
fluctuations in operating results due to a variety of factors, including: the
rate of growth of the markets for its products; market acceptance of the
Company's products and those of its competitors; development and promotional
expenses relating to the introduction of new products or new versions of
existing products; changes in pricing policies by the Company
 
                                      20
<PAGE>
 
and its competitors; the timing of the receipt of orders from major customers;
the timing of shipments; and economic conditions in markets served by the
Company. The Company's expense levels are based, in part, on its expectations
as to future sales and, as a result, operating results would be
disproportionately affected by a reduction in sales or a failure to meet the
Company's sales expectations. The Company believes that its business may be
subject to seasonal fluctuations due to capital expenditure approval cycles of
its customers.
 
  The Company's worldwide sales expose the Company to risks relating to
economic conditions outside of the United States. The Company believes that
recent and ongoing economic turmoil in certain Asian markets may reduce the
Company's sales, although it is difficult to measure or predict the precise
effect of the Asian situation on the Company's results.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash and cash equivalents totaled $8.4 million on December 31, 1997 compared
to $17.7 million on December 31, 1996. In the Fall of 1995, the Company raised
a net $27.7 million through its initial public offering of 2,585,000 shares of
Common Stock, inclusive of 335,000 shares exercised by the underwriters to
cover over-allotments.
 
  A net $3.2 million was provided by operating activities during 1997. Net
income of $5.1 million was supplemented by non-cash charges totaling $0.5
million for depreciation, amortization and deferred compensation, net of
deferred income taxes and by $10.6 million for acquired in-process research
and development, which is included in cash flows used in investing activities.
In support of expanded business activity, accounts receivable and inventory
increased by $19.9 million offset by an increase in payables and accrued
expenses of $7.0 million.
 
  Cash flows used in investing activities in 1997 include $12.4 million for
the acquisition of Reel-Tech, representing cash expended. An additional $2.0
million of consideration for Reel-Tech was represented by the issuance of
75,118 shares of the Company's Common Stock. Investing activities in 1997 also
includes capital expenditures of $5.3 million. These expenditures were
primarily for the purposes of adding manufacturing capacity, providing
equipment for operating efficiencies within the Company's existing facilities
and the acquisition and initial installation of a new company-wide information
system platform. The Company began to occupy newly leased 78,000 square feet
of additional manufacturing, research and office space in December 1997.
 
  The Company's revolving credit agreement with its lending bank, as amended
in 1997, provides for a maximum $20 million revolving credit facility and $6
million in international credit lines. Borrowings under the $20 million
revolving credit facility bear interest at the London InterBank Offered Rate
(LIBOR) plus one and one-quarter percent or prime, determined at time of
borrowing. Borrowings under the international credit lines, of which $4.2
million was outstanding at December 31, 1997, accrue interest at a negotiated
rate approximating the prime rate in the applicable country. The agreement
requires compliance with certain financial ratios and expires December 31,
1999.
 
  The Company believes that its existing cash, together with cash generated
from future operations and its existing bank line of credit, will be
sufficient to satisfy anticipated cash needs to fund working capital and
investments in manufacturing facilities and equipment for its existing
businesses over the next two years. The Company may, from time to time, as
market and business conditions warrant, invest in or acquire complementary
businesses, products or technologies. The Company may require additional
equity or debt financings to fund such activities, which could result in
additional dilution to the Company's shareholders.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders of General Scanning Inc.:
 
  We have audited the accompanying consolidated balance sheets of General
Scanning Inc. (a Massachusetts corporation) and subsidiaries as of December
31, 1997 and 1996 and the related consolidated statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1997. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of General Scanning Inc. and
subsidiaries as of December 31, 1997 and 1996 and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1997
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
 Nature of operations
 
  General Scanning Inc. develops, manufactures and sells its products on a
worldwide basis through two industry segments: laser systems and components;
and thermal printers. The laser systems and components segment provides
products for a wide range of applications in the automotive, electronics,
semiconductor, medical and aircraft industries. The Company's core
technological expertise which is employed in each of these applications is
high speed micropositioning and precise power control of lasers, as well as 2D
and 3D image processing. The thermal printer segment provides a line of
thermal printers for the medical industry.
 
 Basis of presentation
 
  The consolidated financial statements include the accounts of General
Scanning Inc. and its wholly-owned subsidiaries (the "Company"). Significant
intercompany accounts and transactions have been eliminated in consolidation.
The Company's 50% joint venture in the United Kingdom, which had been
accounted for by the equity method, was fully acquired on December 31, 1995 in
a purchase transaction. The acquisition was not material to the Company's
operations.
 
  On November 28, 1997, the Company acquired the assets of Reel-Tech, Inc. for
$14.4 million, which consisted of $12.4 million of cash and 75,118 shares of
General Scanning Inc. common stock. Reel-Tech is an integrator of electronics
components handling systems for marking, lead inspection, parts sorting and
parts packaging. The transaction was accounted for as a purchase for
accounting purposes and, accordingly, the operations of Reel-Tech have been
included in the consolidated financial statements from the date of
acquisition. Acquired in-process research and development of $10.6 million
charged against income in 1997 results from an independent appraisal of Reel-
Tech's intangible assets acquired. Goodwill arising from the transaction of
$3.1 million is being amortized on a straight-line basis over a 10 year
period. Results of operations would not have changed materially for 1997 or
1996 if Reel-Tech had been acquired on January 1, 1996.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In August 1996, the Company acquired View Engineering, Inc. ("View") by
issuing 1,437,060 shares of General Scanning Inc. common stock (after giving
effect to certain adjustments at the closing) in exchange for all of View's
outstanding shares of capital stock, accrued preferred dividends and the net
value of warrants and options. View uses laser image processing technology to
serve applications requiring precision inspection, measurement and process
control. The transaction has been accounted for as a pooling of interests for
accounting purposes and, accordingly, the accompanying consolidated financial
statements have been retroactively restated to include the accounts of View
for all periods presented. Merger expenses include primarily brokers' fees and
legal and accounting costs. The following is a reconciliation of certain
restated amounts with amounts previously reported.

 Use of estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Risks and uncertainties
 
  The Company has experienced, and may continue to experience, fluctuations in
operating results due to a variety of factors, including: the rate of growth
of the markets for laser systems and components and thermal printers; market
acceptance of the Company's products and those of its competitors; development
and promotional expenses relating to the introductions of new products or new
versions of existing products; changes in pricing policies by the Company and
its competitors; the timing of the receipt of orders from major customers; the
timing of shipments and economic conditions in foreign markets.
 
  Certain of the components and materials included in the Company's laser
systems and optical products are currently obtained from single source
suppliers. There can be no assurance that a disruption of this outside supply
would not create substantial manufacturing delays and additional cost to the
Company.
 
 Cash and cash equivalents
 
  Cash and cash equivalents include cash in banks and highly liquid
investments having original maturity dates not exceeding three months. The
investments are stated at cost, which approximates their fair value. The
Company does not believe it is exposed to any significant credit risk on its
cash and cash equivalents.

 Depreciation and amortization
 
  Depreciation and amortization are determined by the straight-line and
declining-balance methods over the estimated useful lives of the owned assets.
Estimated useful lives for buildings and improvements range from 5 to 31 years
and for machinery and equipment from 3 to 15 years. Leasehold improvements are
amortized over the lesser of their useful lives or the lease term, including
option periods expected to be utilized.
 
 Foreign currency
 
  Assets and liabilities of foreign operations are translated from foreign
currencies into U.S. dollars at the exchange rates in effect at the period-
end. Revenues and expenses are translated at the average exchange rate in
effect for the period. The resulting translation adjustments are recorded as a
component of stockholders' equity.
 
  Foreign exchange forward contracts and local currency borrowings are used to
reduce the impact of certain foreign currency balance sheet fluctuations.
Gains and losses from the forward contracts that are not hedges of firm
commitments are accrued at each balance sheet date and included in the
Consolidated Statements of Income as foreign exchange transaction gains
(losses). At December 31, 1997, the Company had such contracts to exchange
foreign currencies (yen, French francs and Deutsche marks) for U.S. dollars
totaling $4,200,000 maturing through May 1998.
 
  In certain circumstances, the Company enters into foreign exchange forward
contracts to reduce the impact of foreign currency fluctuations arising from
foreign currency denominated customer sales. Gains and losses on these
contracts are deferred until the contract matures. At December 31, 1997, 1996
and 1995 there were no such contracts.
 
  To the extent the Company utilizes foreign exchange forward contracts, it
purchases them from major financial institutions for terms that have not
exceeded six months.
 
 Income per share of common stock
 
  In 1997, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 128, Earnings per Share, effective December 15, 1997. Amounts
reported herein for 1996 and 1995 as "Diluted income per common share" are the
same as those reported prior as "Net income per common and common equivalent
share outstanding." Basic income per common share was computed by dividing net
income by the weighted average number of common shares outstanding during the
year. For diluted income per common share, the denominator also includes
dilutive outstanding stock options and warrants determined using the treasury
stock method.

 Revenue recognition
 
  The Company recognizes product revenues generally at the later of the time
of shipment or when substantially all terms and conditions of the sale have
been met. For certain long-term contracts, revenues and profits are recognized
using the percentage-of-completion method. The Company provides for estimated
warranty costs at the time of revenue recognition.
 
 Research and product development expense
 
  Expenditures for research and development of products and manufacturing
processes are expensed as incurred.
 
 Interest
 
  Interest income in 1997 and 1996 is net of $498,000 and $845,000 of interest
expense, respectively, and interest expense in 1995 is net of $373,000 of
interest income.
 
 Impairment of long-lived assets
 
  The Company periodically assesses the realizability of its long-lived assets
in accordance with SFAS No. 121, Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of. Based on its review, the
Company does not believe that any material impairment of its long-lived assets
has occurred.
 
2. INTANGIBLE ASSETS
 
  Purchase price in excess of the fair market value of assets acquired,
including in-process research and development, is recorded as intangible
assets. Such assets arising from the acquisition of the minority interest in
Teradyne Laser Systems, Inc. in 1991 are being amortized on a straight-line
basis over their estimated useful lives of from 3 to 15 years. Goodwill
arising in connection with the acquisition of the assets of Reel-Tech, Inc. in
1997 is being amortized on a straight-line basis over 10 years. Amortization
expense was $109,000 in 1997 and $84,000 in 1996 and 1995.

  The Company's revolving credit agreement with its lending bank was amended
on November 28, 1997. Under its amended terms, the agreement provides for
borrowings of up to $20,000,000 and will expire on December 31, 1999. Interest
on outstanding borrowings is charged at the London InterBank Offered Rate
(LIBOR) plus 1.25% or prime, determined at the time of borrowing. No such debt
was outstanding at December 31, 1997. A commitment fee of 3/8% per annum is
paid quarterly in arrears on the unused portion. Among other restrictions, the
agreement requires a minimum level of tangible net worth and compliance with
certain financial ratios.
 
  Under the terms of the revolving credit agreement, the Company's foreign
operations may borrow up to a maximum of $6,000,000 under lines of credit.
Such debt outstanding at December 31, 1997 was denominated in yen with a
weighted average interest rate of 1.6%.

 Long-term debt
 
  Long-term debt consists of a mortgage payable at 10 3/8% interest,
collateralized by certain land and building. Interest and principal are
payable at $14,906 per month until maturity in February 2000, at which time
the remaining principal of $1,507,516 will be payable. The portion of
principal payable within one year, which is included in current liabilities,
is $19,000.
 
 Fair value of financial instruments
 
  SFAS No. 107, Disclosures About Fair Value of Financial Instruments,
requires disclosure of the year-end fair value of significant financial
instruments, including debt. The Company believes, based upon current terms,
that the carrying value of its debt approximates its fair value.
 
6. DEFERRED COMPENSATION
 
  Officers and certain employees may defer payment of their compensation until
termination of employment or later. Interest on the outstanding balance is
credited quarterly at the prime rate. The portion of deferred compensation
estimated to be due within one year is included in current liabilities.
 
7. STOCKHOLDERS' EQUITY
 
 Recapitalization
 
  In August 1995, the Company's stockholders voted to amend its Articles of
Organization to change the par value of the Company's common stock from $1.00
to $.01. Subsequently, the Board of Directors authorized a 5-for-1 stock
split, effected as a dividend, of the Company's common stock. All share and
per share amounts of common stock for all periods presented have been
retroactively adjusted to reflect the change in par value and the stock split.
 
 Preferred stock
 
  In August 1995, the stockholders approved an amendment to the Articles of
Organization which authorizes 1,000,000 shares of preferred stock, $.01 par
value. The preferred stock is divisible and issuable into one or more series.
The rights and preferences of the different series may be established by the
Board of Directors without further action by the stockholders. The Board of
Directors is authorized, with respect to each series, to fix and determine,
among other things, (i) the dividend rate, (ii) the liquidation preference,
(iii) whether such shares will be convertible into, or exchangeable for, any
other securities and (iv) whether such shares will have voting rights and, if
so, the conditions under which such shares will vote as a separate class.
 
 Shareholder rights plan
 
  On April 30, 1997, the Board of Directors adopted a Shareholders Rights Plan
( the "Plan") and declared a dividend distribution, payable on May 1, 1997, of
one preferred share purchase right under the Plan (each a "Right") for each
outstanding share of common stock of the Company. Under the Plan, each Right,
when exercisable, entitles the holder to purchase from the Company one ten-
thousandth of a share of the Company's Series A Junior Participating Preferred
Stock at a price of $70 per one ten-thousandth of a Preferred Share, subject
to adjustment and to certain exceptions. The value of the one ten-thousandth
interest in a share of Preferred Stock purchasable upon exercise of each Right
is intended to approximate the value of one share of common stock.

                             GENERAL SCANNING INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The rights are not exercisable and cannot be transferred separately from the
common stock until the first to occur of (a) 10 business days after a public
announcement that a person or group of affiliated or associated persons
(excluding certain persons and groups) has acquired beneficial ownership of
20% or more of the outstanding common stock (the date of such an announcement,
a "Shares Acquisition Date"), or (b) 10 business days (subject to extension by
the Board) after the start or announcement of a tender or exchange offer, the
consummation of which would result in beneficial ownership by a person or
group of 20% or more of the outstanding common stock.
 
  Prior to the earlier of (a) the tenth day after the Shares Acquisition Date,
or (b) the expiration of the Rights, the Company may under certain
circumstances redeem the Rights at a price of $0.001 per Right. In certain
cases a Right will entitle the holder to purchase common stock of the Company
or an acquiring company having a value of two times the exercise price of the
Right. Under certain conditions the Company may exchange the Rights for common
stock or preferred stock. The Rights expire on May 1, 2007 unless they are
redeemed by the Company.
 
  So long as the Rights are not transferable separately from the common stock,
the Company will issue one Right with each new share of common stock issued.
The Rights could have certain anti-takeover effects, in that they would cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Board of Directors.
 
 Stock options
 
  The 1992 Stock Option Plan, as amended in August 1995, provides for the
issuance of nonqualified and incentive stock options to purchase up to
1,000,000 shares of the Company's common stock, of which 175,611 were
available for future grant at December 31, 1997. Under this plan, options are
granted at the fair value per share as determined by the Board of Directors at
the date of grant. Outstanding options vest over periods of three or four
years beginning on the date of grant and expire ten years from the date of
grant. The Company's 1981 Stock Option Plan has terminated; however, options
to purchase 197,160 shares of common stock were outstanding under the 1981
Plan at December 31, 1997.
 
  During 1995, the Financial Accounting Standards Board issued SFAS No. 123,
which defines a fair value based method of accounting for an employee stock
option or similar equity instrument and encourages all entities to adopt that
method of accounting for all of their employee stock compensation plans.
However, it also allows an entity to continue to measure compensation costs
for those plans using the method of accounting prescribed by APB 25. Entities
electing to remain with the accounting in APB 25 must make pro forma
disclosures of net income and, if presented, earnings per share as if the fair
value based method of accounting defined in the Statement had been applied.

  The Company has elected to account for its stock-based compensation plans
under APB 25, under which immaterial amounts of compensation have been
recognized. Had compensation cost for these plans been determined consistent
with SFAS No. 123, the Company's net income and earnings per share would have
been reduced to the pro forma amounts below. Because SFAS No. 123 method of
accounting has not been applied to options granted prior to January 1, 1995,
the resulting pro forma compensation costs may not be representative of that
to be expected in future years.

  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions: risk-free interest rate of 5.5% (6.3% in 1996 and 1995), expected
dividend yield of zero, expected lives of 4 years upon vesting and expected
volatility of 50%.
 
  Stock option activity for the years ended December 31, 1995, 1996 and 1997
is presented below. The weighted average fair value of options granted was
$6.74 in 1997 and $4.47 in 1996.

 Warrants
 
  The Company has issued warrants for the purchase of common stock to the
nonemployee members of the Board of Directors. Warrants issued through 1995
vested over periods of three or four years, beginning on the date of grant,
and expire ten years from the date of grant. In 1996, 65,000 of such warrants
were exercised at prices ranging from $1.75 to $2.50 per share and in 1997,
17,500 of such warrants were exercised at $1.75 per share. At December 31,
1997, 37,500 of such warrants, all of which are exercisable, remain
outstanding at exercise prices ranging from $2.36 to $2.50 per share.
 
  During 1995, the stockholders adopted the 1995 Directors' Warrant Plan and
reserved 100,000 shares for future issuance of warrants to nonemployee
Directors under the Plan. The exercise price of such warrants is the fair
market value per share as determined by a committee of the Board of Directors
at the date of grant. The warrants are subject to vesting as determined by
such committee and expire ten years from the date of grant. In 1996, 8,000
such warrants were granted at an exercise price of $20.75 per share and in
1997 8,000 such warrants were granted at an exercise price of $13.00 per
share. In 1997, 4,000 warrants were exercised at prices ranging from $13.00 to
$20.75 per share. At December 31, 1997, 12,000 of such warrants, all of which
are exercisable, remain outstanding at exercise prices ranging from $13.00 to
$20.75 per share.
 
8. BENEFIT PLANS
 
 Employee Stock Ownership Plan
 
  Under the Employee Stock Ownership Plan (ESOP) established in 1989, Company
contributions were in the form of cash or common stock and were allocated to
eligible employees based on their relative compensation. The ESOP was
terminated effective December 31, 1995 and the plan assets have been
distributed to plan participants. Company contributions to the ESOP were
$367,000 in 1995.
 
 Defined contribution plans
 
  The Company has an employee savings defined contribution plan under the
provisions of Section 401(k) of the Internal Revenue Code under which
contributions may be made by its domestic employees. The Company matches the
contributions of participating employees on the basis of the percentages
specified in the plan. Company matching contributions to the plan were
$1,379,000, $1,080,000 and $488,000 for the years ended December 31, 1997,
1996 and 1995, respectively.
 
9. INCOME TAXES
 
  The Company accounts for income taxes using the liability method. Under this
method, deferred tax assets and liabilities are determined based on the
difference between the financial statement and tax bases of assets and
liabilities using the currently enacted tax rates.
 
  The components of income before income taxes for the years ended December 31
are as follows:

  The Company has provided a valuation allowance on the net operating loss
carryforwards and tax credits related to its wholly-owned subsidiary, View
Engineering, Inc., due to the uncertainty of their realizability as a result
of limitations on their utilization in accordance with certain tax laws and
regulations. The operating loss carryforwards expire from 2005 through 2011
and the tax credits expire in 1999 and 2000. Utilization of the operating loss
carryforwards and tax credits is limited to approximately $1.2 million per
year.
 
10. COMMITMENTS AND CONTINGENCIES
 
 Operating leases
 
  The Company leases certain equipment and facilities under operating lease
agreements that expire through 2007. The facility leases require the Company
to pay real estate taxes and other operating costs. For the years ended
December 31, 1997, 1996 and 1995, lease expense was approximately $1,948,000,
$1,787,000 and $1,500,000, respectively.
 
  Minimum lease payments under operating leases expiring subsequent to
December 31, 1997 are:

 Recourse receivables
 
  In Japan, where it is customary to do so, the Company discounts certain
notes receivable at a bank with recourse. The Company's maximum exposure was
$1,858,000 at December 31, 1997. The fair value of the recourse receivables
was not determinable. The Company received cash proceeds relating to the
discounted receivables of $5,262,000, $4,144,000 and $7,188,000 during the
years ended December 31, 1997, 1996 and 1995, respectively.
 
 Legal proceedings and disputes
 
  In August 1996, Robotic Vision Systems, Inc. ("RVSI") commenced an action
against General Scanning in the United States District Court for the Eastern
District of New York. RVSI claimed that General Scanning improperly obtained
proprietary information from RVSI for the purpose of obtaining ownership of
View Engineering, Inc. and of thwarting RVSI's attempts to acquire View
Engineering. The plaintiff was seeking compensatory and punitive damages in an
unspecified amount. In September 1997 and January 1998, that same Court issued
a series of decisions on General Scanning's motion for summary judgment.
Claims were dismissed for: (1) breach of contract, (2) breach of the implied
covenant of good faith and fair dealing, and (3) violations under the
Massachusetts Unfair and Deceptive Business Practices Statute. Claims were not
dismissed for: (1) tortious interference with business relations, (2) fraud of
confidential business information, and (3) unfair competition in contravention
of New York common law. The claims not dismissed, which the Company believes
are without merit and is defending vigorously, are expected to result in a
jury trial during 1998.
 
  Voxel, a prior customer of the Company, asserted in December 1996 that the
Company may not have met certain product specifications. The Company believes
its product has met the necessary specifications. Pursuant to the dispute
resolution section in the Development Agreement between Voxel and the Company,
the matter

has been submitted to binding arbitration. Net accounts receivable at December
31, 1997 and 1996 included approximately $1,012,000 and $931,000,
respectively, of billed and unbilled amounts due from Voxel. Management
believes its case is meritorious and that the amounts due from Voxel are
recoverable.
 
  The Company has certain other contingent liabilities resulting from
litigation and claims incidental to its business, including three patent
infringement suits relating to products currently sold or expected to be sold
by the Company. Management believes that the probable resolution of such
contingencies will not have a materially adverse effect on the Company's
results of operations or financial position.
 
11. RELATED PARTY TRANSACTION
 
  In 1992, the Company's Board of Directors authorized a loan to an officer in
the amount of $160,000 as a reimbursement for certain relocation expenses.
Under the agreement, as amended, the loan has been forgiven and charged as
compensation expense on a pro-rata basis over the five years ending December
31, 1997.

                        CERTIFICATE OF VOTE OF DIRECTORS
                   ESTABLISHING A SERIES OF A CLASS OF STOCK
     

     VOTED:  That, pursuant to the authority granted to and vested in the Board
of Directors of the Corporation in accordance with the provisions of Article IV
B of the Corporation's Restated Articles of Organization, the Board hereby
creates a series of Preferred Stock, par value $.01 per share (the "Preferred
                                                                    ---------
Stock"), of the Corporation and hereby states the designation and number of
- -----
shares, and fixes the preferences, voting powers, qualifications and special or
relative rights or privileges thereof, as follows:

     Section 1.  Designation and Amount.  The shares of such series shall be
                 ----------------------                                     
designated as "Series A Junior Participating Preferred Stock" (the "Series A
                                                                    --------
Preferred Stock") and the number of shares constituting the Series A Preferred
- ---------------         
Stock shall be 3,000. Such number of shares may be increased or decreased by
vote of the Board of Directors; provided, that no decrease shall reduce the
                                --------                                   
number of shares of Series A Preferred Stock to a number less than the number of
shares then outstanding plus the number of shares reserved for issuance upon the
exercise of outstanding options, rights or warrants or upon the conversion of
any outstanding securities issued by the Corporation.

     Section 2.  Dividends and Distributions.
                 --------------------------- 

     (A)   Subject to the rights of the holders of any shares of any series of
Preferred Stock (or any similar stock) ranking prior and superior to the Series
A Preferred Stock with respect to dividends, the holders of shares of Series A
Preferred Stock, in preference to the holders of Common Stock, no par value per
share (the "Common Stock"), of the Corporation, and of any other junior stock,
            ------------
shall be entitled to receive, when, as and if declared by the Board of Directors
out of funds legally available for the purpose, quarterly dividends payable in
cash on the first day of March, June, September and December in each year (each
such date being referred to herein as a "Quarterly Dividend Payment Date"),
                                         --------- -------- ------- ----       
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share or fraction of a share of Series A Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b)
subject to the provision for adjustment hereinafter
<PAGE>
 
                                       2B

set forth, 10,000 times the aggregate per share amount of all cash dividends,
and dividends, and 10,000 times the aggregate per share amount (payable in kind)
of all non-cash dividends or other distributions, other than a dividend payable
in shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time (i) declare a dividend on the Common Stock payable in shares
of Common Stock, (ii) subdivide the outstanding shares of Common Stock, (iii)
combine the outstanding shares of Common Stock into a smaller number of shares
or (iv) issue any of its shares of capital stock in a reclassification of the
outstanding shares of Common Stock (including any such reclassification in
connection with a consolidation or merger in which the Corporation is the
continuing or surviving entity), then in each such case the amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B)   The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

     (C)   Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares, unless the date of issue of such
shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date.  Accrued but unpaid
<PAGE>
 
                                       2C

dividends shall not bear interest. Dividends paid on the shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such shares shall be allocated pro rata on a share-
                                                           --- ----           
by-share basis among all such shares at the time outstanding. The Board of
Directors may fix a record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be not more than 60 days
prior to the date fixed for the payment thereof.

     Section 3. Voting Rights. The holders of shares of Series A Preferred Stock
                ------ ------                                                   
shall have the following voting rights:

     (A)   Subject to the provision for adjustment hereinafter set forth, each
share of Series A Preferred Stock shall entitle the holder thereof to 10,000
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time (i) declare a dividend on the
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
shares of Common Stock, (iii) combine the outstanding shares of Common Stock
into a smaller number of shares or (iv) issue any of its shares of capital stock
in a reclassification of the outstanding shares of Common Stock (including any
such reclassification in connection with a consolidation or merger in which the
Corporation is the continuing or surviving entity), then in each such case the
number of votes per share to which holders of shares of Series A Preferred Stock
were entitled immediately prior to such event shall be adjusted by multiplying
such number by a fraction, the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

     (B)   Except as otherwise provided herein, in any other Certificate of Vote
of Directors establishing a series of Preferred Stock or any similar stock, or
by law, the holders of shares of Series A Preferred Stock and the holders of
shares of Common Stock and any other capital stock of the Corporation having
general voting rights shall vote together as one class on all matters submitted
to a vote of stockholders of the Corporation.

     (C)   Except as set forth herein or as otherwise provided by law, holders
of Series A Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for taking any corporate
action.

Section 4. Certain Restrictions.
           -------------------- 

     (A)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:

          (i)    declare or pay dividends on, make any other distributions on,
or redeem or purchase or otherwise acquire for consideration any shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Preferred Stock;

          (ii)   declare or pay dividends, or make any other distributions, on
any shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except dividends paid ratably on the Series A Preferred Stock and all such
parity stock on which dividends are payable or in arrears in proportion to the
total amounts to which the holders of all such shares are then entitled;

          (iii)  redeem or purchase or otherwise acquire for consideration
shares of any stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Preferred Stock, provided that the
Corporation may at any time redeem, purchase or otherwise acquire shares of any
such junior stock in exchange for shares of any stock of the Corporation ranking
junior either as to dividends or upon dissolution, liquidation or winding up) to
the Series A Preferred Stock; or

          (iv)   redeem or purchase or otherwise acquire for consideration any
shares of Series A Preferred Stock, or any shares of stock ranking on a parity
with the Series A Preferred Stock, except in accordance with a purchase offer
made in writing or by publication (as determined by the Board of Directors) to
all holders of such shares upon such terms as the Board of Directors, after
consideration of the respective annual dividend rates and other relative rights
and preferences of the respective series and classes, shall determine in good
faith will result in fair and equitable treatment among the respective series or
classes.

     (B)  The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.  Reacquired Shares.  Any shares of Series A Preferred Stock
                 -----------------                                         
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Corporation's Restated Articles of Organization or in any other Certificate of
Vote of Directors establishing a series of Preferred Stock or any similar stock
or as otherwise required by law.

     Section 6.  Liquidation, Dissolution or Winding Up. Upon any liquidation,
                 --------------------------------------                       
dissolution or winding up of the Corporation, no distribution shall be made (1)
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received $10,000 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment;
provided that the holders of shares of Series A Preferred Stock shall be
- -------- ----                                                                
entitled to receive an aggregate amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 10,000 times the aggregate amount to
be distributed per share to holders of shares of Common Stock, or (2) to the
holders of shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. In the
event the Corporation shall at any time (i) declare a dividend on the Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding shares
of Common Stock, (iii) combine the outstanding shares of Common Stock into a
smaller number of shares or (iv) issue any of its shares of capital stock in a
reclassification of the outstanding shares of Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Corporation is the continuing or surviving entity), then in each such case the
aggregate amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under the proviso in clause (1) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                                       2F

     Section 7.  Consolidation, Merger, etc. In case the Corporation shall enter
                 --------------------------                                     
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 10,000 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time (i) declare a dividend on the
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
shares of Common Stock, (iii) combine the outstanding shares of Common Stock
into a smaller number of shares or (iv) issue any of its shares of capital stock
in a reclassification of the outstanding shares of Common Stock (including any
such reclassification in connection with a consolidation or merger in which the
Corporation is the continuing or surviving entity), then in each such case the
amount set forth in the preceding sentence with respect to the exchange or
change of shares of Series A Preferred Stock shall be adjusted by multiplying
such amount by a fraction, the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

     Section 8.  No Redemption. The shares of Series A Preferred Stock shall not
                 -------------                                                  
be redeemable.

     Section 9.  Rank. The Series A Preferred Stock shall rank, with respect to
                 ----
the payment of dividends and the distribution of assets, junior to all other
series of the Corporation's preferred stock, unless the terms of any such series
shall provide otherwise.

     Section 10. Amendment. The Restated Articles of Organization, as amended,
                 ---------
of the Corporation shall not be amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of at least two-thirds of the outstanding shares of Series A
Preferred Stock, voting together as a single class; it being understood that
nothing in this Section 10 shall be deemed to restrict the Corporation from
designating additional shares of Series A Preferred Stock if the Board of
Directors determines that it is necessary to do so in order to achieve the
purposes of the Rights Agreement, dated May 1, 1997 between the Corporation and
American Stock Transfer & Trust Company.

holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Stock.

1..9. POSSIBLE EXPANSION:

     Reference is here made to the Agreement of May 19, 1997, Section I
     ("POSSIBLE EXPANSION")

                                       9
<PAGE>
 
     Provided that said expansion shall be feasible, when requested by the
     Lessee, the Lessor will construct an expansion or extension (of not more
     than 40,000 square feet of floor space) to the east of the building if
     required by the Lessee; subject, however, to the following conditions: -



     1.   The Lessor shall be able to secure financing for said expansion from a
          conventional banking institution at then current rate of interest;
     2.   The expansion shall be permitted under all applicable laws and
          regulations-including zoning and building requirements;
     3.   All required permits shall be issued -- including approvals from
          environmental regulatory agencies, state, federal (if necessary) and
          municipal authorities, and any other governmental body that may have
          oversight responsibilities.
     4.   The Lessor and the Lessee shall agree upon the rent, terms and
          conditions of the Lease affecting the present premises herein leased
          and, also, said possible expansion.
     5.   The cost of moving pipes, tubes, wires, valves and any and all devices
          that now service the Waste Water Service Facility, the Fire Protection
          Station and any other support systems for the buildings upon the site
          shall be an expense attributable to the construction costs of the said
          expansion; and shall be factored into the agreed upon rent.

          The obligation to construct said expansion is upon the condition that
          said devices can be moved; that the relevant easements and rights of
          way or access may be relocated along a new path; and that the
          easements and rights of way or access to service same shall be
          established and confirmed in their new path or location with the
          written consent of all parties that may have an interest therein.

          Said relevant easements and rights of way or access shall include, but
          shall not be limited to, the easements and rights of way and access to
          be granted by the Lessor to LOCKHEED MARTIN CORPORATION ("LOCKHEED")
          in order to facilitate the remediation activities to which LOCKHEED is
          committed, and as set forth in Section 1.12 and in Section 1.13.

     6.   It is anticipated that within the area upon which said expansion may
          be requested LOCKHEED shall be engaged in remediation of shallow
          groundwater contamination associated with underground storage tank
          maintained by CONVERSE, INC. LOCKHEED is expected to agree, if the
          Lessor seeks to develop said area, to modify and move its groundwater
          remediation equipment, at its expense, so long as said modification
          and movement is

                                       10
<PAGE>
 
         (i)    essential to said development;

         (ii)   is consistent with LOCKHEED'S remediation obligations;

         (iii)  does not pose an unreasonable risk to human health or to the
                environment;

         (iv)   does not unreasonable prolong remediation activities.

   6.    The Lessee shall have the right to secure or provide the financing for
         said expansion if the Lessor shall be unable to secure same. In the
         event that the said expansion shall be financed by the Lessee, the base
         rent established for said expansion shall be adjusted to reflect any
         cost incurred by the Lessee with respect to said financing and shall be
         appropriately adjusted to said circumstances.

         (Said possible extension is outlined on EXHIBIT B hereto attached.)

1.10.  OPTION TO EXTEND LEASE: (subject and pursuant to the provisions of
       Section 8.20)

       Subject to the conditions set forth in Section 8.20 (A), and provided

       its decision to extend the lease), the Lessee has, and shall have, two
       (2) successive options to extend the lease each for a term of five (5)

                (commencing December 1, 2007 and ending November 30,2012) the
                base rent during said five (5) years shall be established at the
                rate of ninety five (95%) percentum of the then market rent for
                said leased premises. (See Section 8.20 (B).)

            2.  During the second of said two (2) year option terms, (commencing
                December 1, 2012 and ending November 30, 2017) the base rent
                during said second five (5) year term shall be the then market
                rent. (See Section 8.20 (C).)

       B. Notice


            It is agreed that the extension of the lease for said two (2)
            extended terms is, and shall be, upon the condition that the Lessee

<PAGE>
 
            date of the then term of the lease, as stipulated in Section 8.20
            (B) and Section 8.20 (C) hereof.

            Accordingly, with respect to the first extended term of five (5)

            decision to extend the lease for said five (5) year term no later
            than November 30, 2006. With respect to the second extended term of
            five (5) years, the Lessee shall give written notice to the Lessor

      5.6.6)

       The Lessee shall not assign or sublease or sublet the premises or any
       portion thereof unless, in each instance, the Lessor shall have given its

       not be unreasonably withheld, and as provided in Section 5.6 of this
       Indenture of Lease.

       In the event that the rent for said portion subleased or sublet shall
       exceed the rent paid to the Landlord, the increment shall be retained by
       the LESSEE.

       through Section 5.6.6. shall govern and determine assignment, subleasing
       or subletting of this lease. No such assignment, subleasing or subletting

1.12  ENVIRONMENTAL - 21E, etc.

      Reference is made to Section L ("ENVIRONMENTAL - 21E -Etc.") of the
      Agreement of May 19, 1997

      1.  The parties are aware that the site upon which the facilities are
          located has been under review by the Department of Environmental
          Protection ("DEP"); and that the former occupant, GENERAL ELECTRIC
          COMPANY ("G.E."), was named the Responsible Party in a Notice of
          Responsibility dated June 11, 1986. Subsequently, the Lessor received
          a Notice of Responsibility ("N.O.R.") from DEP dated April 16, 1991
          occasioned by bankruptcy proceeding instituted by the parent company
          of Converse, Inc. (Sublessee with respect to G.E. of Building No.2.)

      2.  The contamination of the site resulted from releases of gasoline, oil
          and other substances by G.E. and its sub-lessee, Converse, Inc.

      3.  G.E. accepted and assumed the responsibility to conduct remediation
          activities in 

                                       12
<PAGE>
 
          accordance with plans submitted to, and approved by, D. E. P.
          (including matters referred to in the N. O. R. mailed to the Lessor
          dated, as stated, April 16, 1991 and occasioned by the bankruptcy
          proceedings aforesaid). This responsibility has been expressly
          acknowledged and assumed by the successors to G.E., i.e., MARTIN
          MARIETTA CORPORATION and its successor, LOCKHEED MARTIN CORPORATION
          ("LOCKHEED").

          LOCKHEED is committed to (and is engaged in) the necessary remediation
          process as approved by, and under the oversight of, D. E. P.

      4.  Lessor will seek reports of the engineers engaged by LOCKHEED. These,
          as well as progress reports relating to the remediation activities as
          received by the Lessor, shall be submitted by the Lessor to the
          Lessee.

      5.  LESSOR shall indemnify the Lessee from any claims made by third
          parties unrelated and not in privity to Lessee arising out of any
          contamination of the site that has occurred prior to the occupancy of
          the leased premises by the Lessee. The Lessor and the Lessee shall
          consult and co-operate with each other in the event that any such
          claims shall arise.

      6.  The parties acknowledge that the Lessor is currently engaged in
          negotiations with LOCKHEED with respect to the continuing
          responsibility of LOCKHEED (subject to the oversight of the D. E. P.)
          and to confirm and define liability, indemnification and the nature of
          related documentation and agreements that may be agreed upon. Lessee
          agrees to cooperate with respect thereto if requested in order that
          remediation activities shall continue and be facilitated to further
          the best interests of the parties.

      7.  In connection with the response and remediation activities upon the
          Facilities to which LOCKHEED is committed, the Lessor reserves the
          right to agree to permanent Activity and Use Limitations ("AUL"), as
          shall be specified and agreed upon, with respect to certain specific
          areas within the said Facilities or Complex. Said AUL shall be
          consistent with the Massachusetts Contingency Plan, 30 C.M.R. Section
          40,00, et seq ("MCP") and approved by the DEP. The Lessee
          acknowledges herewith that the Lessor has reserved, and does reserve,
          the right to agree to said AUL in connection with the continuing
          responsibility of LOCKHEED and the remediation response and activities
          in which LOCKHEED is, and shall be, engaged.

      8.  The Lessee shall comply strictly with all relevant Environmental
          Control Laws.

          In particular, and without limitation, the Lessee shall comply with,
          and shall be subject to,

          a. the Comprehensive Environmental Response, Compensation, and
             Liability Act of 1980 (CERCLA"), as amended by the Superfund
             Amendment and Reauthorization Act of 1986, 42 U.S.C. Section 9601
             et seq.; and

                                       13
<PAGE>
 
          b. the Massachusetts Oil and Hazardous Materials Release Prevention
             and Response Act, as amended, Massachusetts General Laws,
             Annotated, Chapter 21 E.

          In connection with the foregoing, the Lessee shall comply with the
          provisions set forth in Section 5.3.

1.13  EASEMENTS AND RIGHTS OF ACCESS

    A. Lessor shall retain existing easements and rights of way over the
       facilities and the premises (and shall reserve additional easements and
       rights of access) in furtherance of its management obligations and

       remain upon the premises to perform work upon, and to service, water and
       fire protection facilities and lines, Waste Water Treatment Facility, and
       for any other purpose required by the Lessor. Easements and rights of
       access have been granted for this purpose to AMETEK, as successor to G.
       E. Further, Lessor retains, and shall have, the right to grant easements
       in connection with said management and oversight (including easements to
       LOCKHEED MARTIN CORPORATION in order to facilitate its remediation of the
       site as required by D. E. P. - See 1.12 above).

       Said easements and rights of access shall not unreasonably interfere with
       the business activities of the Lessee.

    B. To facilitate the remediation activities to which LOCKHEED is committed
       (and in which it is now engaged), as indicated in Section 1.12, the
       Lessor intends to grant, and shall grant, right of access over and upon
       the Facilities or Complex of which the premises leased hereunder are a
       part. The easement to be granted to LOCKHEED shall include the right to
       pass and repass, the right to remove soil and the right to engage in soil
       vapor extraction activities as well as creek sediment remediation.

       The Lessee does herewith agree and consent to the grant of said easement,
       right of access and right to pass and repass to LOCKHEED to facilitate
       said remediation; and the Lessee shall not interfere with, or impede, the
       grant of said easement or the remediation conducted in connection
       therewith.

    C. The LESSEE shall permit the other LESSEE in the Complex (that is, AMETEK)
       to pass and repass over the premises leased to GENERAL SCANNING, INC. to
       enable AMETEK to have access to the Waste Water Treatment Facility and to
       the other northerly portions of the Complex that are leased to AMETEK, as
       shown on EXHIBIT A; provided that this right of access granted to AMETEK
       shall not be used in such manner as to unreasonable interfere with the
       business activities of the LESSEE (i.e. GENERAL SCANNING, INC.).

    Agreement, dated May 19, 1997.

       1. Said Building No.2 is serviced by a new and "state of the art" Waste
          Water Service Facility (placed on line within the last year) and

          that in the event a replacement of the said facility (beyond
          maintenance and operation) the tenants using same shall be responsible
          for said replacement and shall contribute thereto upon the agreed upon
          the formula established to determine use and allocation of costs of
          operation (to be based upon degree of usage and employee population of
          the Tenants).

          Lessee shall have no responsibility with respect to replacement of the
          facility.

          The LESSEE shall assume, and shall comply with, all obligations
          imposed upon the LESSEE under applicable Law as a permitee or
          permitted user of said Waste Water Treatment Facility.

          interruptions insurance that shall cover or reinstate the Lessee from

          In the event that any interruption of the business activities of the
          LESSEE shall result from, or be attributable to, any failure or
          disruption of, or damage to, said Waste Water Treatment Facility, the
          LESSEE shall make no claim against the LESSOR and shall not look to
          the LESSOR for recovery of any damages or loss resulting therefrom.

                      but not limited to, the provisions of Section 5.3 hereof);

          (f)  there shall be existing an "Event of Default" (defined in Section
               7.1).

5.6.4   Notice of Proposed Assignment, Subletting or Subleasing

        The Lessee shall deliver to the Lessor written notice of any proposed
        assignment or sublease or subletting; and said notice shall specify the

             sublessee or subtenant as may reasonably be required for the Lessor
             to make the determination referred to in Section 5.6.3 above
             (provided, however, that Lessor shall hold such information
             confidential; - the Lessor, however, having, and hereby being
             granted, and retaining, the right to release said information to

             confidential basis);

             or subleasing or subletting is proposed to be made;
        (d)  in the case of a proposed assignment or subleasing or subletting

        (e)  in the case of a proposed assignment or subleasing or subletting
             pursuant to Section 5.6.1 above, such information as may be

             assignment or subleasing or subletting complies with the
             requirements of said Section 5.6.1 (said information including, but
             not limited to, the matters set forth in said Section 5.6.1.).

     No partial subletting shall be permitted except as provided in Section
     5.6.1.

     If the Lessor shall consent to the proposed assignment or subleasing or
     subletting, as the case may be, then, in such event, the Lessee may
     thereafter assign sublease or sublet (the whole, but not part, of the
     Premises) pursuant to the notice from the Lessee, given as required
     hereunder; provided, however, that if such assignment or sublease shall not
     be executed and delivered to the Lessee within ninety (90) days after the
     date of the consent by the Lessor, the said consent shall be deemed null
     and void; and the provisions of Sections 5.6.2 and 5.6.3 shall then again
     be applicable and shall thereafter be followed as to the proposed
     assignment or subleasing or subletting.

       of Rent, etc.):

                                       29
<PAGE>
 
       In addition, in the case of any assignment or subleasing or subletting by
       the Lessee, including, but not limited to, any assignment or subleasing
       or subletting as to which Landlord may consent, such assignment,
       subleasing or subletting (and the consent of the Lessor if given thereto)
       shall be upon the express and further condition, covenant and agreement
       (and the Lessee hereby covenants and agrees) that the Lessee shall
       continue to be liable and be responsible for, the Annual Fixed Rent,
       additional rent and other charges to be paid pursuant to this Indenture
       of Lease and shall continue to be liable and responsible for the
       covenants and obligations of the Lessee under this Indenture of Lease.
       Therefore it is agreed, under Section 5.6.6(A) and (B) and (C), as
       follows:

5.6.6. Responsibility in the Event of Assignment or Subleasing

       (A) It is, and shall be, a condition of the validity of any assignment or
           subleasing or subletting, under Section 5.6.1 above, or consented to
           under Section 5.6.3 above, that the assignee or sublessee or
           subtenant shall agree directly with the Lessor, in form reasonably
           satisfactory to the Lessor, to be bound by all the obligations of
           this Indenture of Lease; including, without limitation, the
                                               ------------------
           obligation to pay the rent and other amounts provided for under this
           Lease and including, without limitation, the provisions under ARTICLE
           V, including, specifically, Section 5.3 and Section 5.6 through 5.6.6
           thereof. In any event, such assignment or subleasing or subletting
           (whether or not consented to by the Lessor and whether under the
           provisions of Section 5.6.1 or otherwise) shall not relieve the
           Lessee named herein of any of the obligations of the Lessee under
           this Indenture of Lease. Therefore, the Lessee shall remain fully and
           primarily liable for all payments, as and when due, required under
           this Indenture of Lease as well as for the performance of all
           obligations of the Lessee hereunder.

           The liability of the Lessee and of such assignee (or sublessee or
           subtenant, as the case may be) shall be, and shall remain, joint and
           several.

           Further, and notwithstanding the foregoing, the provisions hereof
           shall not constitute a recognition (by way of substitution) of the
           assignment or of the assignee or sublessee or subtenant thereunder.
           At the option of the Lessor, upon the termination of the Lease
           established by this Indenture, any said assignment or sublease or
           subletting shall be terminated.

       (B) As additional rent, the Lessee shall promptly reimburse the Lessor
           for reasonable out of pocket, legal and other expenses incurred by
           Landlord in connection with any request by the Lessee for consent to
           any proposed assignment or sublease or subletting.

       (C) Any consent by the Lessor to an assignment or subleasing or
           subletting under any of the provisions of Sections 5.6.1 or 5.6.3
           shall not be consent to any other or future assignment or subleasing
           or subletting; - and shall not in any way be construed to relieve the
           Lessee from the obligation of obtaining the express consent in
           writing of the Lessor to any further assignment or subletting.

          liability for injury, loss, accident or damage to any person or
          property and from any claims, actions, proceedings and expenses and

                         misconduct of the Lessee or of the Lessee's
                         contractors, licensees, invitees, agents, independent
                         contractors or employees; or

                    (ii) any use made or thing done or occurring on the premises
                         leased hereunder after the date that possession of the
                         said premises is first delivered to Lessee and until
                         the end of the Lease Term or extensions thereof; and
                         thereafter, so long as the Lessee shall be in occupancy
                         of any part of the Premises; provided, however, that
                         said use, activity or occurrence shall not be due to
                         the omission, fault, willful act, negligence or other
                         misconduct of the Lessor or its contractors, agents or
                         employees; or


          (b)  shall result from the failure of the Lessee to perform and
               discharge any of its covenants and obligations under this Lease.

          (c)  In the event that any said occurrence shall in part be due to, or
               in part caused by, the fault or negligence of LESSOR, the
               liability of, and indemnification by, the LESSEE hereunder shall
               be delimited only to the extent of the relative degree or
                            ----
               proportion of fault of the LESSOR in causing or contributing to
               said occurrence. In the event that said occurrence shall, in
               part, be due to the fault or negligence of the Lessor, the Lessee
               shall be liable to the Lessor and shall indemnify the Lessor to
               the degree or extent of the fault or negligence of the Lessee.

     (B)  INSURANCE

          The Lessee, further, covenants and agrees to maintain, with

          comprehensive general liability insurance with a broad form
          comprehensive liability endorsement covering the premises leased
          hereunder insuring the LESSOR (as an additional insured) as well as
          the Lessee with limits which shall, at the commencement of the Term,
          be at least equal to those stated in Section 1.1; and from time to
          time during the

                                       31
<PAGE>
 
      Term, shall be for such higher limits, if any, as are customarily carried
      in Greater Boston with respect to similar properties or which may
      reasonably be required by the LESSOR. Further, the Lessee shall maintain
      workmen's compensation insurance with statutory limits covering all of the
      employees of the LESSEE working in the premises leased hereunder.

      The Lessee shall deposit with Lessor on or before the Commencement Date

      designating the Lessor as insured, as above provided, and bearing the
      endorsement that the policies will not be canceled until after thirty (30)
      days' written notice to Lessor.

      Lessor as an additional insured), as above stipulated, the Lessee shall

      insure or indemnify the Lessor (or its mortgagees) for a period of no less
      than twelve (12) months from and after the date of such fire, loss, damage
      or other casualty.

5.8   Furnishings, etc. of the Lessee at Lessee's Risk

      It is herewith agreed that all of the furnishings, fixtures, equipment,
      effects and property of every kind, nature and description of the Lessee
      and of all persons claiming by, through or under the Lessee which, during
      the continuance of this Lease or any occupancy of the Premises by the
      Lessee or anyone claiming under the Lessee, may be on the Premises or
      elsewhere in the Facilities or Complex, shall be at the sole risk and
      hazard of the Lessee; - and if the whole or any part thereof shall be
      destroyed or damaged by fire, water or otherwise, or by the leakage or
      bursting of water pipes, steam pipes, or other pipes, by theft or from any
      other cause, no part of said loss or damage is to be charged to or be
      borne by the Lessor; - except that LESSOR shall not be indemnified or held
      harmless or exonerated from any liability to the Lessee or to any other
      person, for any injury, loss, damage or liability that shall have been
      caused by the negligence or fault of the Lessor.

5.9   Right of Entry

      The Lessee agrees to permit Landlord and its agents to examine the
      premises leased hereunder at reasonable times and to require that the
      Lessee make any repairs or replacements for the proper maintenance and
      upkeep of the building and of the premises leased hereunder. Further, the
      Lessor may remove at the expense of the Lessee, any alterations,
      additions, signs, curtains, blinds, shades, awnings, aerials, flagpoles,
      or the like not consented to in writing.

      The Lessor may enter the premises, at reasonable times, to show the
      building and the premises to prospective tenants during the twelve (12)
      months preceding expiration of the initial Term or expiration of any
      extended term. Further, the Lessor may enter into and upon any part of the

                                      32
<PAGE>
 
      premises leased hereunder, at all reasonable times, for the purpose of
      showing same to prospective purchasers and mortgagees. (All persons must
      sign the log book upon entering the premises and note the time upon
      exiting the same.)

5.10  Floor Load: Prevention of Vibration and Noise

      The Lessee agrees not to place a load upon the Premises exceeding an
      average rate of 200 pounds of live load per square foot of floor area
      (partitions shall be considered as part of the live load); and not to move
      any safe, vault or other heavy equipment in, about or out of the Premises
      except in such manner and at such time as the Lessor shall, in each,
      instance authorize.

      Notwithstanding the foregoing, the LESSEE shall not place any load upon
                                                      ---
      the said Premises which will damage same, or which may cause damage
      thereto, even though said load shall be less than 200 pounds of live load
                                              ----
      per square foot of floor space. LESSEE agrees, therefore, that it shall
      not place any load upon or in said premises which will or may damage same.

      The weight limitation above set forth (200) pounds of live load per square
      foot) shall be adjusted downword in the event that the engineers the
      Lessor shall determine that said limitation of weight is excessive and
      requires adjustment downwards under the circumstances of the building. The
      Lessee agrees to assent to said reduction of weight limitation by said
      engineers as they shall determine.

      The Lessee agrees that business machines and mechanical equipment which
      cause vibration or noise that may be transmitted to the structure of the
      building leased hereunder shall be installed, maintained and used by the
      Lessee in such manner as to eliminate such vibration or noise.

5.11  Personal Property Taxes

      The Lessee agrees to pay promptly when due all taxes which may be imposed
      upon personal property upon the premises herein leased (including, without
      limitation, fixtures and equipment) to whomever assessed.

5.12  Compliance with Laws

      a.  The Lessee agrees to comply, and shall comply with, all applicable
          Legal Requirements now or hereafter in force which shall impose a duty
          on the Lessee or the Lessee relating to, or as a result of, the use or
          occupancy of the premises leased hereunder; - provided that Lessee
          shall not be required to make any alterations or additions to the
          structure, roof, exterior and load bearing walls, foundation,
          structural floor slabs and other structural elements of the Buildings
          unless the same are required by such Legal Requirements as a result of
          or in connection with use or occupancy by the Lessee of the premises
          leased hereunder. The Lessee shall promptly pay all fines, penalties
          and damages that may arise out of or be imposed because of its failure
          to comply with the provisions of this Section 5.12.

                                      33
<PAGE>
 
      b.  Not in limitation of the foregoing, the LESSEE shall conduct and carry
          on its activities within the Premises in accordance with all and any
          permits or licenses (wherever any said permit or license shall be
          required) properly applied for and issued by any and all governmental
          authority having jurisdiction or responsibility over same.

      c.  The LESSEE shall, at its sole expense, obtain and renew any and all
          permits or licenses necessary for the LESSEE to be or become a
          permitted user or permittee of the Waste Water Treatment Facility
          referred to in Section 1.14 and in Section 2.2.


5.13  Payment of Litigation Expenses

      The Lessee agrees to pay, as additional rent, all reasonable costs,
      counsel and other fees incurred by the Lessor in connection with the
      successful enforcement by the Lessor of any obligations of the Lessee
      under this Indenture of Lease.

6.1   Fire and Casualty - Termination of Restoration; Rent Adjustment

      (A) Restoration - Termination

          If, during the initial or extended Term or Terms of the lease, the
          building leased hereunder (including the Site that affects the said
          leased premises) are damaged by fire or other casualty, and in the
          event that such fire or casualty damage cannot, in the ordinary
          course, reasonably be expected to be repaired within one hundred
          eighty (180) days from the time that repair work would commence,
          Lessor may, at its election, terminate this Lease by notice given to
          Lessee within sixty 60) days after the date of such fire or other
          casualty, specifying the effective date of termination. The effective
          date of termination specified by the Lessor shall not be less than
          thirty (30) days nor more than forty-five (45) days after the date of
          notice of such termination.

          If the LESSOR does not elect to terminate the Lease (in the event of
                             ---
          the foregoing), the LESSOR will proceed with due diligence to restore
          the premises to their condition prior to the fire or casualty.

      (B) Damage during Last Year

          If the said building and premises shall be damaged by fire or other
          casualty during the last year of the initial term or during the last
          year of each of the extended terms of the lease, and such fire or
          casualty damage cannot, in the ordinary course, reasonably be expected
          to be repaired within one hundred eighty (180) days from the time that
          said work would commence (and/or, as to special work or work which
          requires long lead time, then if such work cannot reasonably be
          expected to be repaired within such additional time as is

                                      34
<PAGE>
 
          reasonable under the circumstances given the nature of the work),
          then, in such event, the Lessee may, at its election, terminate this
          Lease by notice given to Landlord within sixty (60) days after the
          date of such fire or other casualty, specifying the effective date of
          termination. The effective date of termination specified by Tenant
          shall be not less than thirty (30) days nor more than forty-five (45)
          days after the date of notice of such termination.

      Unless terminated pursuant to the foregoing provisions, this Lease shall
      remain in full force and effect following any such damage; subject,
      however, to the following provisions.

      (C) Rent Adjustment in the Event of Temporary Displacement

          Notwithstanding the provisions of this Section 6.1, if the building
          leased hereunder shall be damaged by fire or casualty to such an
          extent that Lessee cannot operate in any reasonable portion thereof
          and, therefore, must temporarily shut down its usual operations in the
          building leased hereunder (for the reason that it is not reasonably
          tenantable for ninety (90) days or more), then Tenant shall have the
          right to seek other facilities until the said building shall be
          restored in accordance with the requirements of this Section 6.1. In
          the event that the provisions of the this Paragraph shall become
          applicable, the Annual Fixed Rent and additional rent shall abate from
          the date of the fire or other casualty giving rise to the
          applicability of this Paragraph until the Premises are so restored.
          Upon such restoration, Lessee shall return to the Premises and,
          commencing with the date the premises are so restored, the LESSEE
          shall resume paying Annual Fixed Rent and additional rent

      (D) Insurance Proceeds: Restoration

          In the event that the said building or the Premises or the Facilities
          (or Complex), or any part thereof; are damaged by fire or other
          casualty and, if this Lease is not terminated (pursuant to the
          provisions of the foregoing); or in the event that the Lessor or the
          Lessee shall have no right to terminate this Lease; --- provided that
          the holder of any mortgage (which includes the building leased
          hereunder to the Lessee as a part of the mortgaged premises) shall
          allow the net insurance proceeds to be applied to the restoration of
          the damaged building or the damaged Premises or Facilities, then, in
          such event, and promptly after such damage and after the determination
          of the net amount of insurance proceeds available, the Lessor shall
          use due diligence to restore the building or the Premises or the
          damaged Facilities, in the event of damage thereto, into proper
          condition for use and occupation.

          In such event, a fair and equitable part of the Annual Fixed Rent,
          proportionate and according to the nature and extent of the damage to
          the building shall be abated until the said building shall have been
          restored substantially to said proper condition for use and occupation
          by the Lessor; except for punch list items and long lead items.

          No portion of said insurance proceeds shall be applied to any damage
          or loss to any

                                      35
<PAGE>
 
          furniture, fixtures, apparatus or equipment belonging to, or installed
          by, or paid by, the Lessee.

          Said restoration by the Lessor (by means of the proceeds of insurance
          permitted to be so used by the holder of any mortgage upon the said
          Premises, as aforesaid), shall be completed within one (1) year from
          the date of the casualty or loss; provided, however, that said one (1)
          year period shall be extended in the event that any delay in
          completion of the restoration shall be due to causes beyond the
          reasonable control of the Lessor. In no event, however, shall the said
          extension be beyond eighteen (18) months beyond the date of the
          casualty or loss.

          In the event that said restoration shall not be substantially
          completed within said period or periods of time, the Lessee shall have
          the right to terminate this lease at any time after the expiration of
          such one (1) year period (or eighteen (18) months, as extended) until
          the restoration shall be substantially completed.

          Such termination shall take effect as of the thirtieth (30th) day
          after the date of receipt by Lessor of notice from the Lessee, with
          the same force and effect as if such date were the date originally
          established as the expiration date of this lease; provided, however,
          that if, within thirty (30) days after receipt by the Lessor of notice
          of said of termination from the Lessee, said restoration shall have
          substantially completed, then (in the event of such restoration), the
          notice of termination from the Lessee shall be of no force and effect;
          and this Lease and the Lease Term shall continue in full force and
          effect.

6.2   Loss Caused by Uninsured Risk

      Notwithstanding anything to the contrary contained in this Lease, if the
      building or Premises or the Facilities shall be substantially damaged by
      fire or casualty as the result of a risk not covered by the forms of
                                               ---
      casualty insurance at the time maintained by Lessor or by the LESSEE (with
      the LESSOR named as an insured or a loss payee), and such fire or casualty
      damage cannot, in the ordinary course, reasonably be expected to be
      repaired within ninety (90) days from the time that repair work would
      commence, the Lessor may, at its election, terminate the Term of this
      Lease by notice to the Lessee given within thirty (30) days after such
      loss. If the Lessor shall give such notice, then this Lease shall
      terminate as of the date of such notice with the same force and effect as
      if such date were the date originally established as the expiration date
      hereof.

6.3   Condemnation - Taking by Right of Eminent Domain

      In the event that there shall occur a taking by condemnation or by right
      of eminent domain, resulting in the taking of the entirety of the building
      leased hereunder, or if there shall occur a taking of such portion of the
      premises leased hereunder as to render the balance unsuitable for the
      purposes of the Lessee (even after reconstruction to the maximum extent
      practicable in the then circumstances), then, in such event, both the
      Lessor and the Lessee shall have the right to terminate this Lease by
      written notice to the other of its desire to do so; - provided that such
      notice shall be delivered not later than thirty (30) days after the Lessee
      shall have been deprived

                                      36
<PAGE>
 
      of possession. If either party shall give such written notice, then this
      Lease shall terminate as of the date of such notice with the same force
      and effect as if such date were the date originally established as the
      expiration date hereof.

      Further, if so much of the building leased hereunder shall be taken under
      said condemnation proceedings, as to render continued operation of the
      said buildings uneconomic (as a result of the said taking), both the
      Lessor and the Lessee shall have the right to terminate this Lease by
      giving notice to the other party of the desire of the party giving said
      notice to so terminate the lease, no later than thirty (30) days after
      LESSEE has been deprived of possession of the said Premises (or such
      portion thereof as may be taken). If either party shall give such notice,
      then this Lease shall terminate as of the date of such notice with the
      same force and effect as if such date were the date originally established
      as the expiration date hereof.

      In the event that

          (i)   any part of the premises leased hereunder be so taken or
                condemned during the initial Lease Term or any extension
                thereof, and

         (ii)   should, in such event, this Lease not be terminated in 
                                                  ---                         
                accordance with the foregoing provisions, and  

         (iii)  upon such occurrence, if provided that the holder of any
                mortgage (that includes the premises leased hereunder as part of
                the mortgaged premises) allows the net condemnation proceeds to
                be applied to the restoration of the Premises so taken or
                condemned,

                then, and in such event:-

                The Lessor agrees that, after the determination of the net
                amount of condemnation proceeds available to the Lessor, the
                Lessor shall use due diligence to put what may remain of the
                Premises into proper condition for use and occupation as nearly
                like the condition of the Premises prior to such taking as shall
                be practicable (excluding, however, any furniture, fixtures or
                                ---------              
                equipment of Tenant, or any other items installed or paid for by
                the Lessee).

                If the Premises shall be affected by any exercise of the power
                of eminent domain, then the Annual Fixed Rent and Lessee's share
                of real estate taxes shall be justly and equitably abated and
                reduced according to the nature and extent of the loss of use
                thereof suffered by Lessee.

6.4   Awards resulting from eminent domain takings

      The Lessor shall have, and hereby reserves, to itself any and all rights
      to receive awards made for damages to the premises leased hereunder, or to
      the Complex or to the Facilities (or any portion thereof) and, or with
      respect to the leasehold hereby created, which awards may result or accrue
      by reason of exercise of right of eminent domain, by condemnation
      proceedings pursuant thereto, or by reason of anything lawfully done in
      pursuance of public, governmental or other

                                      37
<PAGE>
 
      authority. The Lessee hereby grants, releases and assigns to the Lessor
      all rights of the Lessee to such awards. The Lessee covenants and agrees
      to execute and deliver such further instruments of assignments, with
      respect to said awards, and other assurances thereof as the Lessee may
      from, time to time request; - and if the Lessee shall fail to execute and
      deliver the same within fifteen (15) days after notice from the Lessor,
      the Lessee hereby covenants and agrees that the Lessor is, and shall be,
      irrevocably designated and appointed as its attorney-in-fact to execute
      and deliver in Lessee's name and behalf all such further instruments of
      assignments and other assurances thereof that shall conform with the
      provisions hereof.

      Nothing contained herein shall be construed to prevent the Lessee from
      prosecuting in any condemnation proceeding a claim for the value of any
      personal property or usual trade fixtures in the building or upon the
      Premises leased hereunder that belong to, or were installed by, the
      Lessee, or at the expense of the Lessee; or claims arising from the cost
      of relocation and moving; - provided, however, that such action, and any
      resulting award shall not affect or diminish the amount of compensation
      otherwise recoverable by Landlord from the taking authority.

      DEFAULT" by Lessee:  Remedies accruing to Lessor (Section 7.1)

      (A) The following occurrences or actions by the Lessee (listed hereinafter
          under Section 7.1(A) (I) through (iv) are, and shall constitute,

                 or

          (ii)   The Lessee shall neglect or fail to perform or observe any
                 other covenant herein contained required to be performed or
                 observed by the Lessee, and the Lessee shall fail to remedy the
                 same within thirty (30) days after notice to the Lessee
                 specifying such neglect or failure; or, if such failure be of
                 such a nature that the Lessee cannot reasonably remedy the same
                 within sixty (60) days, the Lessee shall fail to commence
                 promptly to remedy the same and to prosecute such remedy to

                      under any present or future Federal, State or other
                      statute, law or regulation for the relief of debtors; or
                 (d)  Shall seek or consent to or acquiesce in the appointment
                      of any trustee, receiver or liquidator of the Lessee or of
                      all or any substantial part of its properties; or
                 (e)  Shall admit in writing its inability to pay its debts
                      generally as they become due; or
                 (f)  A petition shall be filed against the Lessee in bankruptcy
                      or under any other law seeking any reorganization,
                      arrangement, composition, readjustment, liquidation,
                      dissolution, or similar relief under any present or future
                      Federal, State or other statute, law or regulation and
                      said petition shall remain undismissed for an aggregate of
                      sixty (60) days (whether or not consecutive), or
                 (g)  A debtor in possession, or a trustee, or a receiver, or a
                      liquidator of the Lessee of all or any substantial part of
                      its properties or of the premises leased hereunder, shall
                      be appointed with or without the consent or acquiescence
                      of the Lessee and such appointment shall remain unvacated
                      or unstayed for an aggregate of sixty (60) days (whether
                      or not consecutive).

      (B) In the Event of the Occurrence of any said "Events of Default" by the
          Lessee

          In the event that any of the said "Events of Default" shall occur, or
          if the Lessee shall commit any of the activity that shall constitute
          any of said "Events of Default", then, and in any of said cases
          (notwithstanding any license of a former breach of covenant or waiver
          of the benefit hereof or consent in a former instance), the Lessor
          lawfully may, immediately or at any time thereafter, and without
          demand or further notice, terminate this Lease by notice to the
          Lessee, specifying a date not less than ten (10) days after the giving
          of such notice on which this Lease shall terminate. This Lease shall,
          then, come to an end on the date specified therein as fully and
          completely as if such date were the date herein originally fixed for
          the expiration of the Lease Term (Lessee hereby waiving any rights of
          redemption); and the Lessee will then quit and surrender the Premises
          to the Lessor, but Lessee shall remain liable as hereinafter provided.

      (C) Entry by Lessor upon Such Termination

          If this Lease shall have been terminated as provided in this Article,
          then the Lessor may, without notice, re-enter the Premises, either by
          force, summary proceedings, ejectment or otherwise, and remove and
          dispossess the Lessee and all other persons and any and all property
          from the same, as if this Lease had not been made, and the Lessee
          hereby waives the service of notice of intention to re-enter or to
          institute legal proceedings to that end.

                                      39

      (D) Responsibility of Lessee: Rent

          In the event that this Lease shall be terminated under any of the
          provisions contained in the Article VII (particularly, Section 7.1),
          or shall be otherwise terminated as a result of the breach by the
          Lessee of any of its obligations under this lease, the Lessee
          covenants and agrees that, in such case, the Lessee shall forthwith
          pay on the days originally fixed herein for the payment thereof,
          amounts equal to the several installments of rent and other charges
          reserved as they would, under the terms of this Lease, become due if
          this Lease had not been terminated or if the Lessee had not entered or
          re-entered, as aforesaid. The Lessee, in such case, shall pay, and
          shall be liable for, all said amounts whether the Premises be relet or
          remain vacant, in whole or in part, or for a period less than the
          remainder of the Term, or for the whole thereof. However, if the
          Premises shall be relet by the Lessor, the Lessee shall be entitled to
          a credit in the net amount of rent and other charges received by the
          Lessor as a result of said reletting, after deduction of all expenses
          incurred in reletting the Premises (including, without limitation,
          remodeling costs, brokerage fees and the like), and in collecting the
          rent in connection therewith, in the following manner:

          Amounts received by the Lessor, after reletting shall first be applied
          against such expenses incurred by the Lessor, until the all said
          expenses shall have been recovered; and until such recovery, the
          Lessee shall pay, as of each day when a payment would fall due under
          this Lease, the amount which the Lessee is obligated to pay under the
          terms of this Lease. When, and if, such expenses shall have been
          completely recovered, the amounts received from reletting by Lessor
          that shall not have been previously applied to recovery of said
          expenses, shall be credited against the obligations of the Lessee as
          of each day when a payment would fall due under this Lease. After said
          credit, the net amount of the said payments (in fulfillment of the
          obligations of the Lessee) shall be payable by the Lessee.

      (E) Liquidated Damages

          At any time after such termination, and whether or not Landlord shall
          have collected any damages pursuant to the foregoing, and at the
          election of the Lessor, the Lessee shall pay to the Lessor, as
          liquidated final damages and in lieu of all other damages beyond the
          date of notice from the Lessor to the Lessee, such sum that shall
          represent the amount of the excess, if any, of the total rent and
          other benefits, including payment of taxes, (which would have accrued
          to the Lessor under this Lease - from the date of giving of such
          notice through the expiration date of the then unexpired Lease Term -
          or extension thereof) -- over and above -- the then cash rental value
          (in advance) of the Premises for the balance of the said Lease term
          (or extension thereof)

      (F) Rights of Lessor upon Entry after an "EVENT OF DEFAULT"

          In case of any Event of Default, re-entry, dispossession by summary
                         ----- -- -------                                    
          proceedings or otherwise, the Lessee may

          (1)  re-let the Premises or any part or parts thereof; either in the
          name of the Lessor, or

                                      40
<PAGE>
 
          otherwise, for a term or for terms which may, at the option of the
          Lessor, be equal to, or less than, or exceed, the period which would
          otherwise have constituted the balance of the Term of this Lease; and
          may, further, grant concessions or free rent to the extent that Lessor
          considers advisable or necessary to re-let the same; and

          (2)  may make such alterations, repairs and decorations in the
          Premises as Landlord in its sole judgment considers advisable or
          necessary for the purpose of reletting the Premises. The making of
          such alterations, repairs and decorations shall not operate or be
          construed to release the Lessee from liability hereunder, as
          aforesaid. The Lessor shall in no event be liable in any way
          whatsoever for failure to re-let the Premises, or, in the event that
          the Premises are re-let, for failure to collect the rent under re-
          letting. The Lessee hereby expressly waives any and all rights of
          redemption granted by or under any present or future laws in the event
          the Lessee shall be evicted or dispossessed, or in the event that the
          Lessor shall obtain possession of the Premises in consequence of the
          violation by the Lessee of any of the covenants and conditions of this
          Lease whether said violation shall constitute an "Event of Default" or
          otherwise.

      (G) Remedies are Cumulative and not Exclusive upon Default

          The specified remedies to which the Lessor may resort hereunder are
          not intended to be exclusive of any remedies or means of redress to
          which the Lessor may, at any time, be entitled lawfully. The Lessor
          may invoke any remedy (including the remedy of specific performance)
          allowed at law or in equity as though specific remedies were not
          herein provided for. Further, nothing contained in this Lease shall
          limit or prejudice the right of the Lessor to file or enter a claim
          for its damages resulting from said termination of this lease, and
          obtain, in proceedings for bankruptcy or insolvency brought by or on
          behalf of the Lessee, an amount equal to the maximum allowed by any
          statute or rule of law in effect at the time when, and governing the
          proceedings in which, the damages are to be proved; whether or not the
          amount be greater, equal to, or less than the amount of the loss or
          damages referred to above.

7.2   Default by the Lessor of its Obligations under this Lease

      The Lessor shall in no event be in default in the performance of any of
      the obligations of the Lessor hereunder unless and until Lessor shall have
      failed to perform such obligations within thirty (30) days after notice
      from the Lessee to the Lessor properly specifying wherein Lessor has
      failed to perform any such obligation. In the event, however, that the
      default by the Lessor is of such nature as to require additional time
      (beyond said thirty (30) days), the time in which the Lessor shall be
      required to correct said default, shall be extended for a reasonable and
      commensurate time.

                                 ARTICLE VIII
                                 ------------
                                        
                           MISCELLANEOUS PROVISIONS
                           ------------------------

                                      41
<PAGE>
 
8.1  Extra Hazardous Use

     The Lessee covenants and agrees that the Lessee will not do, or permit
     anything to be done, in or upon the Premises, or bring in anything or keep
     anything therein, which shall increase the rate of any insurance that the
     Lessor shall maintain in respect to the Premises or the Facilities or the
     Complex above the standard rate applicable to the said premises for
     occupancy and use for the purposes (and use) to which the Lessee has agreed
     to devote and occupy the Premises. Further, the Lessee agrees that, in the
     event that the Lessee shall cause an increase to the Lessor in the rate of
     said insurance, the Lessee will promptly pay to the Lessor, within thirty
     (30) days after demand, any such increase resulting therefrom; which shall
     be due and payable as additional rent. The Lessor shall give notice to the
     Lessee of any such increase promptly after the Lessor shall receive
     knowledge of the same; provided that the Lessee shall be responsible for
     any such increases applicable to both the period prior to and after any
     such notice.

8.2  Waiver

     Failure on the part of the Lessor or the Lessee to complain of any action
     or non-action on the part of the other, no matter how long the same may
     continue, shall never be a waiver by the Lessor or by the Lessee,
     respectively, of any of their respective rights hereunder. Further, no
     waiver at any time of any of the provisions hereof by the Lessor or by the
     Lessee shall be construed as a waiver of any of the other provisions
     hereof; and a waiver at any time of any of the provisions hereof shall not
     be construed as a waiver at any subsequent time of the same provisions. The
     consent or approval of the Lessor or of the Lessee to or of any action by
     the other requiring such consent or approval shall not be construed to
     waive or render unnecessary the consent (or approval to) of the Lessor or
     of the Lessee to or of subsequent similar act by the other.

     No payment by the Lessee, or acceptance by the Lessor, of a lesser amount
     than shall be due from the Lessee to the Lessor shall be treated otherwise
     than as a payment on account. The acceptance by Lessor of a check for a
     lesser amount with an endorsement or statement thereon, or upon any letter
     accompanying such check, that such lesser amount is payment in full, shall
     be given no effect, and the Lessor may accept such check without prejudice
     to any other rights or remedies which the Lessor may have against the
     Lessee.

8.3  Cumulative Remedies
  
     The specific remedies to which the Lessor may resort under the terms of
     this Lease are cumulative and are not intended to be exclusive of any other
     remedies or means of redress to which such party may be lawfully entitled
     in case of any breach or threatened breach by the Lessee of any provisions
     of this Lease. In addition to the other remedies provided in this Lease,
     the Lessor shall be entitled to the restraint by injunction of the
     violation or attempted or threatened violation of any of the covenants,
     conditions or provisions of this Lease or to a decree compelling specific
     performance of any such covenants, conditions or provisions.

8.4  Quiet Enjoyment  

                                       42
<PAGE>
 
     If the Lessee shall perform all of the obligations of the Lessee under this
     Lease (including, but not limited to, payment of the rent and observing,
     keeping and performing all of the terms and provisions of this Lease to be
     observed, kept and performed by the Lessee), then, in such event, the
     Lessee shall lawfully, peaceably and quietly have, hold, occupy and enjoy
     the Premises during the initial Term (and any extension thereof), without
     hindrance or ejection by any persons lawfully claiming under the Lessor to
     have title to the Premises superior to the Lease, subject, however, to the
     terms of this Lease. The foregoing covenant of quiet enjoyment is in lieu
     of any other covenant, express or implied. It is understood and agreed that
     this covenant and any and all other covenants of the Lessor contained in
     this Lease shall be binding upon the Lessor and its successors only with
     respect to breaches that shall occur during the respective ownership of the
     interest of the Lessor by the Lessor or by the successors to or of the
     Lessor, as the case may be.
     
8.5  Notice to Mortgagee and Ground Lessor

     After receiving notice from any person, firm or other entity that it holds
     a mortgage which includes the Premises as part of the mortgaged premises,
     or that it is the ground Landlord under a lease with the Lessor, as ground
     Lessee or ground Tenant, which includes the Premises as a part of the
     demised premises, no notice from the Lessee to the Lessor shall be
     effective unless and until a copy of the same is given to such holder of a
     mortgage or ground Landlord; and the curing of any of defaults committed by
     the Lessor hereunder by such mortgage holder or ground Landlord within a
     reasonable time thereafter (including a reasonable time to obtain
     possession of the premises if the mortgagee or ground Landlord elects to do
     so) shall be treated as performance by Lessor hereunder. For the purposes
     of this Section 8.5 or Section 8.15, the term "mortgage" shall include a
     mortgage on a leasehold interest of the Lessor (but not one on leasehold
     interest of the Lessee).

8.6  Assignment of Rents

     With reference to any assignment by the Lessor of the interest of the
     Lessor in this Lease, or the rents payable hereunder, conditional in nature
     or otherwise, which assignment is made to the holder of a mortgage or
     ground lease on property which includes the Premises, the Lessee agrees, as
     follows: -

           (A) That the execution of said assignment by the Lessor, and the
               acceptance thereof by the holder of such mortgage or the ground
               Landlord, shall never be treated as an assumption by such holder
               or ground Landlord of any of the obligations of Lessor hereunder,
               unless such holder, or ground Landlord, shall, by notice sent to
               the Lessee, specifically otherwise elect; and

           (B) That, except as aforesaid, such mortgage holder or ground
               Landlord shall be treated as having assumed the obligations of
               the Lessor hereunder only upon foreclosure of such holder's
               mortgage and the taking of possession of the Premises, or, in the
               case of a ground Landlord, the assumption of the position of

                                       43
<PAGE>
 
               the Lessor by such ground Landlord.

           (C) The Lessor reserves, and shall have, the unrestricted right and
               power to grant mortgages with the premises herein leased as
               security under said mortgage. Further, the Lessor shall have the
               unrestricted right and power to make any assignment of the rents
               or benefits (in whole or in part) to any lender or third party
               accruing to the Lessor under this lease, with or without a
               mortgage conveyance.

8.7  Surrender

     No act or thing done by the Lessor during the Lease Term (or extension
     thereof) shall be deemed an acceptance of a surrender of the Premises, and
     no agreement to accept such surrender shall be valid, unless in writing
     signed by the Lessor. No employee of the Lessor or any agents of the Lessor
     shall have any power to accept the keys of the Premises prior to the
     termination of this Lease. The delivery of keys to any employee of the
     Lessor or to agents of the Lessor shall not operate as a termination of the
     Lease or a surrender of the Premises.

8.8  Brokerage

     (A) The Lessee warrants and represents that the Lessee has not dealt with
         any broker in connection with the consummation of this Lease other than
                                                                      ----------
         the Recognized Brokers designated in Section 1.7 hereof. In the event
         -------------------------------------------------------              
         any claim is made against the Lessor relative to dealings by the Lessee
         with brokers other than the Recognized Brokers designated in Section
         1.7 hereof, the Lessee shall defend the claim against the Lessor with
         counsel selected by the Lessee that shall, however, first be approved
         by the Lessor (which approval will not be unreasonably withheld); and
         the Lessee shall save harmless and shall indemnify Lessor on account of
         loss, cost or damage which may arise by reason of such claim.

     (B) The Lessor warrants and represents that the Lessor has not dealt with
         any broker in connection with the consummation of this Lease other than
                                                                      ----------
         the Recognized Brokers designated in Section 1.7 hereof; and in the
         -------------------------------------------------------   
         event any claim is made against the Lessee relative to dealings by the
         Lessor with brokers other than the Recognized Brokers designated in
         Section 1.7 hereof, the Lessor shall defend the claim against the
         Lessee with counsel of selected by the Lessor; - and the Lessor shall
         save harmless and indemnify the Lessee on account of loss, cost or
         damage which may arise by reason of such claim.

     (C) The Lessor shall be solely responsible for the payment of brokerage
         -------------------------------------------------------------------
         commissions to the Recognized Brokers designated in Section 1.1 hereof.
         ---------------------------------------------------------------------- 

8.9  Invalidity of Particular Provisions

     If any term or provision of this Lease, or the application thereof to any
     person or circumstance shall, to any extent, be invalid or unenforceable,
     the remainder of this Lease, or the application of

                                       44
<PAGE>
 
     such term or provision to persons or circumstances other than those as to
     which it is held invalid or unenforceable, shall not be affected thereby,
     and each term and provision of this Lease shall be valid and be enforced to
     the fullest extent permitted by law.

8.10 Provisions Binding, Etc.

     The obligations of this Lease shall run with the land, and except as herein
     otherwise provided, the terms hereof shall be binding upon and shall inure
     to the benefit of the successors and assigns, respectively, of the Lessor
     and of the Lessee (and, if Lessee shall be an individual, upon and to his
     heirs, executors, administrators, successors and assigns). Each term and
     each provision of this Lease to be performed by the Lessee shall be
     construed to be both a covenant and a condition. The reference contained to
     successors and assigns of the Lessee is not intended to constitute, and
     shall not constitute, a consent to subleasing or subletting or assignment
     by the Lessee.

8.11 Recording

     This Indenture of Lease shall not be recorded.

     The Lessee agrees not to record the within Lease; but each party hereto
                       ---
     agrees, on the request of the other, to execute a so-called Notice of Lease
     in form recordable and complying with applicable law and reasonably
     satisfactory to the attorneys of the Lessor and of the Lessee. In no event
     shall such document set forth rent or other charges payable by Lessee under
     this Lease; and any such document shall expressly state that it is
     executed pursuant to the provisions contained in this Lease, and is not
     intended to vary the terms and conditions of this Lease.

8.12 Notices

     Whenever, by the terms of this Lease, notice shall or may be given or
     delivered either to the Lessor or to the Lessee, such notice shall be in
     writing and shall be sent by registered or certified mail, postage prepaid,
     as follows:-

         If intended for the Lessor, it shall be addressed to the Lessor at the
         address set forth under Section 1.2.1 of this Indenture of Lease (or to
         such other address or addresses as may from time to time hereafter be
         designated by the Lessor) with a copy to the Lessor, Care of and
         Attention to its General Counsel, Frank N. Dardeno, Esquire, 424
         Broadway, Somerville, Massachusetts 02145).

         If intended for the Lessee, addressed to the Lessee, at 500 Arsenal
         Street, Watertown, Massachusetts 02172, Attention: George Hrono, Senior
         Vice President (or to such other address or addresses as may from time
         to time hereafter be designated by the Lessee by like notice), with a
         copy thereof to the then General Counsel of the Lessee (as designated
         by the Lessee) and, if the Lessor shall so elect, to the General
         Manager or Officer in Charge of the Lessee at the premises leased
         hereunder to the Lessee.

     Except as otherwise provided herein, all such notices shall be effective
     when received; provided that

       (i)  if receipt is refused, notice shall be effective upon the first
            occasion that such receipt is refused or
       (ii) if the notice is unable to be delivered due to a change of address
            of which no notice was given, then, in such event, notice shall be
            effective upon the date such delivery was attempted.

8.13 When Lease Becomes Binding

     Employees or agents of the Lessor have no authority to make or agree to
     make a lease or any other agreement or undertaking in connection herewith.
     The submission of this document for examination and negotiation does not
     constitute an offer to lease, or a reservation of, or option for, the
     Premises. This document shall become effective and binding only upon the
     execution and delivery hereof by both the Lessor and the Lessee. All
     negotiations, considerations, representations and understandings between
     the Lessor and the Lessee are incorporated herein and may be modified or
     altered only by written agreement between the Lessor and the Lessee. No act
     or omission of any employee or agent of the Lessor or of the Lessee shall
     alter, change or modify any of the provisions hereof unless said act or
     omission shall, in each instance, be specifically authorized, in writing,
     by the Lessor or the Lessee (as the case may be).

8.14 Section Headings

     The headings of the Sections as well as the titles of the Articles
     throughout this Lease are for convenience and reference only, and the words
     contained therein shall in no way be held to explain, modify, amplify or
     aid in the interpretation, construction or meaning of the provisions of
     this Lease.

8.15 Rights of Mortgagee

       This Lease shall be subject and subordinate to any mortgage now or
     hereafter on the Premises (the premises leased hereunder) or the Facilities
     or the Complex, and to each advance made, or hereafter to be made, under
     any mortgage, and to all renewals, modifications, consolidations,
     replacements and extensions thereof and all substitutions therefor;
     provided that the holder of such mortgage agrees to recognize the rights of
     ---------------------------------------------------------------------------
     the Lessee under this Lease (including the right to use and occupy the
     ---------------------------
     Premises) upon the payment of rent and other charges payable by the Lessee
     under this Lease and the performance by the Lessee of the obligations of
     the Lessee hereunder.

       In confirmation of such subordination and recognition, the Lessee shall
     execute and deliver promptly such instruments of subordination and
     recognition as such mortgagee may reasonably request.

                                       46
<PAGE>
 
        In the event that any mortgagee or its respective successor in title
     shall succeed to the interest of the Lessor, then, this Lease shall
     nevertheless continue in full force and effect and the Lessee shall attorn
                                                                         ------
     (and does hereby agree to attorn) to such mortgagee or successor; and to
                               ------
     recognize such mortgagee or successor as its landlord.


        With respect to any mortgage (which includes the Premises) that has been
     executed and recorded prior to the date of this Lease, if the holder of
                           -----
     said mortgage shall so elect, this Lease and the rights of Lessee
     hereunder, shall be superior in right to the rights of such holder, with
                         --------
     the same force and effect as if this Lease had been executed, delivered and
     recorded, or a statutory Notice thereof recorded, prior to the execution,
     delivery and recording of any such mortgage. The election of any such
     holder shall become effective upon either notice from such holder to the
     Lessee (which notice shall be given in the same fashion as notices from the
     Lessor to the Lessee are to be given hereunder) or by the recording in the
     appropriate registry or recorder's office of an instrument in which such
     holder subordinates its rights under such mortgage to this Lease.

        If in connection with obtaining financing for the Premises (the premises
     leased hereunder) or the Complex or Facilities, a bank, insurance company,
     pension trust or other institutional lender shall request reasonable
     modifications in this Lease as a condition to such financing, the Lessee
     will not unreasonably withhold, delay or condition its consent thereto;
     provided that such modifications do not increase the monetary obligations
     of the Lessee hereunder or materially adversely affect the leasehold
     interest hereby created.

8.16 Status Report

     Recognizing that both parties may find it necessary to establish to third
     parties (such as accountants, banks, mortgagees or the like), the then
     current status of performance hereunder, either party, on the request of
     the other made from time to time, will promptly furnish to the Lessor, or
     the holder of any mortgage encumbering the Premises or the Complex or the
     Facilities, or to the Lessee, as the case may be, a statement of the status
     of any matter pertaining to this Lease, including, without limitation,
     acknowledgments that (or the extent to which) each party is in compliance
     with its obligations under the terms of this Lease. Any such statement
     delivered by the Lessee pursuant to this Section 8.16 may be relied upon by
     any prospective purchaser or mortgagee of the Premises or the Complex or
     the Facilities or any prospective assignee of any mortgagee of the
     Premises.

8.17 Self-Help

     If the Lessee shall, at any time, default in the performance of any
     obligation under this Lease, the Lessor shall have the right, but shall not
     be obligated, to enter upon the Premises and to perform such obligation
     notwithstanding the fact that no specific provision for such substituted
     performance by the Lessor is made in this Lease with respect to such
     default. In performing such obligation, the Lessor may make any payment of
     money or perform any other act.

       All sums so paid by the Lessor (together with interest at the rate of two
                                                                          -- ---
       and one-half percentage

     successor to The First National Bank of Boston) and all costs and expenses
     ----------------------------------------------
     in connection with the performance of any such act by the Lessor, shall be
     deemed to be additional rent under this Lease and shall be payable to
     Landlord immediately on demand.

     The Lessor may exercise the foregoing rights without waiving any other of
     its rights and without releasing the Lessee from any of its obligations
     under this Lease.

8.18 Holding Over

     Any holding over by the Lessee after the expiration of the term of this
     Lease shall be treated as a tenancy at sufferance at double the rents and
     other charges herein (prorated on a daily basis) and shall otherwise be on
     the terms and conditions set forth in this Lease, as far as applicable;
     provided, however, that neither the foregoing nor any other term or
     provision of this Lease shall be deemed to permit the Lessee to retain
     possession of the Premises or hold over in the Premises after the
     expiration or earlier termination of the Lease Term.

8.19 Non-Subrogation

     Any insurance carried by either party with respect to the Premises or
     property therein or occurrences thereon shall, if it can be so written
     without additional premium or with an additional premium which the other
     party agrees to pay, include a clause or endorsement denying to the insurer
     rights of subrogation against the other party to the extent rights have
     been waived by the insured prior to occurrence of injury or loss. Each
     party, notwithstanding any provisions of this Lease to the contrary, hereby
     waives any rights of recovery against the other for injury or loss due to
     hazards covered by such insurance to the extent of the indemnification
     received thereunder.

8.20 Extension Option

 (A) Conditions

     Provided that at the time of exercise of the option to extend and at the
     commencement date of the extension option period -

      (i)   there exists no Event of Default (defined in Section 7.1); and
                         --                                               
      (ii)  this Lease shall then be in full force and effect; and
      (iii) the Lessee has neither assigned this Lease nor sublet the Premises;

       Then, if said three (3) conditions shall prevail, the Lessee shall have
       the right to extend the Term hereof upon all the same terms, conditions,
       covenants and agreements herein contained (except for the Annual Fixed
       Rent which shall be adjusted during the option period as herein below set
       forth) for two (2) periods of five (5) years as hereinafter set forth.
       The option period is sometimes herein referred to as the "Extended Term".

                                       48
<PAGE>
 
  (B) First Five (5) Year Extended Term
     
      If the Lessee desires to exercise the option to extend the Term for the
      first five (5) year extended term (commencing December 1, 2007 and ending
      November 30, 2012), then the Lessee shall deliver notice to the Lessor of
      the request of the Lessee for quotation by the Lessor of Ninety Five (95%)
      per centum of the annual fair market rent for the Premises as of the
      commencement date of the first extension period. Such quotation shall be
      based on the use of the Premises as comparable office space in the Boston
      North Suburban Market (hereinafter called the "Annual Market Rent").
      Within thirty (30) days after receipt by the Lessor of said notice from
      the Lessee requesting such a quotation, the Lessor shall notify the Lessee
      of the quotation of the Lessor of Ninety Five (95%) per centum of the
      Annual Market Rent. Said Ninety Five (95%) per centum of the Annual Market
      Rent, however, shall, in no event, be less than the Annual Fixed Rent for
      the last year of the Original or Initial Term. The Lessee shall deliver
      said notice to the Lessor of its request for quotation by the Lessor of
      Ninety-five (95%) per centum of the annual fair market rent not earlier
      than fifteen (15) months nor later than Twelve months prior to the
      expiration term of this lease.

      In order to exercise its rights hereunder, the Lessee, (and within fifteen
      (15) days after receipt by the Lessee of the quotation from the Lessor of
      Ninety Five (95%) per centum of the Annual Market Rent) shall give written
      notice to the Lessor that it exercises its option to extend the Term of
      this Lease; in which case the Term of this Lease shall be extended for an
      additional term of five (5) years upon all of the same terms, conditions,
      covenants and agreements contained in this Lease except that the Annual
      Fixed Rent shall be equal to Ninety Five (95%) per centum of the Annual
      Market Rent as quoted by Lessor; provided, however (and as aforesaid), in
      no event shall the Annual Fixed Rent payable during the Extended Term be
      less than the Annual Fixed Rent for the last year of the Original Term.
      Upon the giving of such notice, this Lease and the Lease Term hereof shall
      be extended, for the first five (5) year Extended Term, without the
      necessity for the execution of any additional documents, except the Lessor
      and Lessee agree to enter into an instrument in writing setting forth the
      Annual Fixed Rent for the Extended Term but the failure to so enter into
      such a written instrument shall not negate the exercise of the applicable
      option to extend. Upon the giving of such notice of extension as aforesaid
      all references herein to the Lease Term or the term of this Lease shall be
      construed as referring to the Lease Term, as so extended, unless the
      context clearly otherwise requires.

  (C) Second Five (5) Year Extended Term

      If the Lessee desires to exercise the option to extend the term of the
      Lease for a second five (5) year Term (commencing December 1, 2012 and
      ending November 30, 2017), the Lessee shall deliver written notice to the
      Lessor of its desire and intention to extend the term of the lease for
      said additional five (5) year term not earlier than fifteen (15) months
                                         ------------------------------------
      nor later than twelve months prior to the expiration of the first five (5)
      ----------------------------------
      year extended term. The same terms and conditions of this Indenture of
      Lease in force and effect during the initial ten (10) year term; and
      during the first five (5) year extended term of the lease shall apply and
      shall be in force and effect during the said second extended five (5) year
      term of this lease; except, however, that the
                          ------
     

                                       49
<PAGE>
 
      Annual Fixed Rent during the said second five (5) year term (commencing on
      December 1, 2012) shall be the then market rent, to wit, the "Annual Fixed
      Market Rent"), as hereinafter set forth.

      If the Lessee desires to exercise the option to extend this lease for the
      said second five (5) year term (commencing December 1, 2012 and ending
      November 30, 2017), then the Lessee shall give notice to the Lessor, as
      aforesaid, not earlier than fifteen (15) months nor later than twelve (12)
                     ----------------------------------------------------------
      months prior to the expiration of the first five (5) year extension of
      ------------
      this Lease, of the request of the Lessee for quotation by the Lessor of
      the annual fair market rent for the Premises as of the commencement date
      of the second five (5) year extension period. Such quotation shall be
      based on the use of the Premises as comparable office space in the Boston
      North Suburban Market (hereinafter called the "Annual Market Rent").
      Within thirty (30) days after receipt by the Lessor of said notice from
      the Lessee requesting such a quotation, the Lessor shall notify the Lessee
      of the quotation of the Lessor of the Annual Market Rent. Said Annual
      Market Rent, however, shall, in no event, be less than the greater of the
                                                   ----     
      Annual Fixed Rent for the last year of the Original or Initial Term or the
      last prior of the first five (5) year extended term of this lease.

      In order to exercise its rights hereunder, the Lessee, (and within fifteen
      (15) days after receipt by the Lessee of the quotation from the Lessor of
      the Annual Market Rent) shall give written notice to the Lessor that it
      exercises its option to extend the Term of this Lease; in which case the
      Term of this Lease shall be extended for an additional term of five (5)
      years upon all of the same terms, conditions, covenants and agreements
      contained in this Lease except that the Annual Fixed Rent shall be equal
      to Annual Market Rent as quoted by Lessee; provided, however (and as
      aforesaid), in no event shall the Annual Fixed Rent payable during the
      Extended Term be less than the greater of the Annual Fixed Rent for the
      last year of the Original or Initial Term or the last year of the first
      five (5) year extended term of this lease. Upon the giving of such notice,
      this Lease and the Lease Term hereof shall be extended, for the second
      five (5) year Extended Term, without the necessity for the execution of
      any additional documents, except that Landlord and Tenant agree to enter
      into an instrument in writing setting forth the Annual Fixed Rent for the
      said second five (5) year Extended Term; but the failure to so enter into
      such a written instrument shall not negate the exercise of the applicable
      option to extend. Upon the giving of such notice of extension as aforesaid
      all references herein to the Lease Term or the term of this Lease shall be
      construed as referring to the Lease Term, as so extended, unless the
      context clearly otherwise requires.

      Notwithstanding anything herein contained to the contrary, in no event
      shall the Lease Term hereof be extended after the expiration of the said
      second five (5) year Extended Term (to wit:- in no event shall this lease
      be extended beyond November 30, 2017).

(D)   Option Granted to Extend for Two Five (5) year Terms Only

      The Lessee is herewith granted the option to extend this lease for two
      five (5) year Extended Terms; said options to the lease for said two
      Extended Terms to be exercised in accordance

                                       50
<PAGE>
 
        with the provisions herein above stated; and upon the terms, rent and
        provisions therein stipulated. The LESSEE is granted no further or other
        options to extend this Lease by the foregoing terms and provisions

8.21    Lessee Shall Look Only to the Interest of the Lessor to the Premises
        herein Leased.

        The Lessee specifically agrees to look solely to then equity interest of
        the Lessor in the specific premises herein leased to the Lessee for
        recovery of any judgment from Landlord. It is specifically agreed upon
        that neither the Lessor (original or successor), nor any beneficiary of
        any Trust which shall hold the interest of the Lessor, and no Trustee of
        any said Trust shall ever be personally liable for any such judgment, or
        for the payment of any monetary obligation to the Lessee. The provision
        contained in the foregoing sentence is not intended to, and shall not,
        limit any right that the Lessee might otherwise have to obtain
        injunctive relief against the Lessor or the successors in interest to
        the Lessor; provided, however, that said action (or any action that may
                    --------
        be brought by the Lessee) shall not involve, entail, or result in, the
        personal liability of the Lessor (original or successor), or of any
        successor Trustee to the persons named herein as the Lessor, or of any
        beneficiary of any Trust of which any person holding the interest of the
        Lessor is Trustee; and provided that said action shall not require the
        Lessor, its successors in title, or its trustees, or beneficiaries of
        said Trust to respond in monetary damages from the assets of the Lessor
        other than the equity interest of the Lessor, aforesaid, in the specific
        -----
        premises herein leased to the Lessee (the Premises). In no event shall
        Lessor ever be liable to Lessee for any indirect or consequential
        damages suffered or claims by the Lessee from whatever cause.

8.21.1  The Trustees of Lessor and Beneficiaries Not Personally Liable.

        In the event the LESSEE shall recover any judgment against the LESSOR,
        said judgment may, and shall, be satisfied only and exclusively from the
        premises specifically leased to the LESSEE hereunder.. Neither the
        Trustees of the Trust holding the interest of the LESSOR nor the
        beneficiaries of said Trust (or any of them) shall be liable for, or
        shall have any personal liability or responsibility in respect to said
        judgment. The LESSEE agrees that it shall look only to the interest of
        the LESSOR in said premises leased hereunder; shall not seek to recover
        said judgment against the Trustees or the Beneficiaries in their
        individual capacities; and shall not look to any interest of the Lessor
        in any assets held or owned by the Lessor other than the premises herein
        specifically leased to the Lessee.

8.22    Late Payment

        If the Lessor shall not have received any payment or installment of rent
        on or before the date (the "Due Date") on which the same first becomes
        payable under this Lease, the amount of such payment or installment
        shall bear interest ten (10) days after the Due Date through and
                   --------  
        including the date such payment or installment shall be received by
        Landlord, at a rate equal to the lesser of
                                         ------    

                                       51
<PAGE>
 
       (I)  the rate announced by Bank Boston, successor to The First National
            Bank of Boston, from time to time as its prime or base rate (or if
            such rate is no longer available, a comparable rate reasonably
            selected by the Lessor), plus two percent (2%), or
       (ii) the maximum applicable legal rate, if any.

       Such interest shall be deemed additional rent and shall be paid by the
       Lessee to the Lessor upon demand.

8.23   Governing Law

       This Lease shall be governed exclusively by the provisions hereof and by
       the law of the Commonwealth of Massachusetts, as the same may from time 
       to time exist.

8.24   This Indenture of Lease comprises a total of 53 pages consisting of eight
       (8) ARTICLES (I through VIII); along with the following Exhibits:

       EXHIBIT A:  showing the premises lease hereunder.
       EXHIBIT B:  showing layout of future extension.
       EXHIBIT C:  Agreement dated May 19, 1997.

8.25   This Lease Conditional Upon Release of Premises by AMETEK

       As indicated in the Agreement between the parties, dated May 19, 1997
       (referred to in Section 1.1), the premises herein leased are part of the
       Facilities leased to AMETEK AEROSPACE PRODUCTS, INC. ("AMETEK"),
       successor to GENERAL ELECTRIC COMPANY, under an Indenture of Lease dated
       November 13, 1968. This Indenture of Lease with GENERAL SCANNING, INC.
       is, therefore, upon the express condition that said AMETEK shall have
       released to the Lessor from its Lease the premises herein described and
       intended to be leased to the Lessee (See Section 1.5). (The foregoing
       Section 8.25 is now moot.)

8.26   Counsel

       Each party has had its own and independent counsel prepare, review and
       revise this Indenture of Lease prior to its execution and delivery; and
       each party has relied on its own independent counsel in respect to this
       Lease. (Said counsel, Frederick C. Morse and Frank N. Dardeno, Sr., have
       initialed each page of each of the four counterparts of this Lease.)

8.27   Dispute Resolution

       The parties shall seek to resolve any disputes that may arise with
       respect to this Indenture of Lease in good faith negotiations. If,
       despite the best efforts of the parties, said dispute shall not be
       resolved, the parties shall not resort to litigation in the Courts unless
                                                                          ------
       and until resolution of said dispute shall have been sought by means of
           -----
       submission of said dispute to third party and

       disinterested arbitration proceedings.

This Indenture of Lease is EXECUTED as a sealed instrument in two or more
counterparts, each of which shall be deemed to be an original, as of this 15th
day of July, 1997.

I. POSSIBLE EXPANSION

     Provided that said expansion shall be feasible, when requested, the Lessor
     will construct an expansion or extension (of not more than 40,000 square
     feet of floor space) to the east of the building if required by the Lessor
     (see K, 1, d below); subject, however, /to the following conditions:-

     1.  The Lessee shall be able to secure financing for said expansion from a
         conventional banking institution at then current rate of interest;
     2.  The expansion shall be permitted under all applicable laws and
         regulations - including zoning and building requirements
     3.  All required permits shall be issued -- including approvals from
         environmental regulatory agencies, state, federal (if necessary) and
         municipal authorities, and any other governmental body that may have
         oversight responsibilities.
     4.  The Lessor and the Lessee shall agree upon the rent, terms and
         conditions of the Lease affecting the present premises an said possible
         expansion.
     5.  The cost of moving pipes, tubes, wires, valves and any and all devices
         that now service the Waste Water Service Facility, the Fire Protection
         Station and any other support system for the buildings upon the site
         shall be an expense attributable to the construction costs of the said
         expansion; and shall be factored into the agreed upon rent.

         The obligation to construct said expansion is upon the condition that
         said devices can be moved; that the relevant easements and rights of
         way or access may be relocated along a new path; and that the easements
         and rights of way or access to service same shall be established and
         confirmed in their new path or location with the written consent of
         all parties that may have an interest therein.

     6.  The Lessee shall have the right to secure to provide the financing for
         said expansion if the Lessor shall be unable to secure same. In the
         event that the said expansion shall be financed by the Lessee, the base
         rent established for said expansion shall be adjusted to reflect any
         cost incurred by the Lessee with respect to said financing and shall be
         appropriately adjusted to said circumstances.

     Lessor shall secure from its engineers an opinion as to the feasibility of
     the expansion, as set forth under Section O, 4)

J. OPTION TO EXTEND LEASE

     Lessee shall have two successive options to extend the lease each for a
     term of five (5) years upon the same terms and conditions of the original
     ten (10) year term except that the base rent (see Section E. 1 above)
     shall be established, as follows:

                                       9
<PAGE>
 
         It is agreed that

           a.  With respect to the first of said two five (5) year option terms,
               the base rent shall be established during said five (5) years at
               the rate of ninety five (95%) percentum of the then market rent;

           b.  With respect the second of the said two (2) five year option
               terms, the base rent during said second five (5) year term shall
               be the then market rent.

K. SUBLEASING

         Lessee shall not sublease or sublet the premises or any portion thereof
         unless, in each in each instance, the Lessor shall have given its
         approval in writing to said sublease or subletting; which approval the
         Lessor shall not unreasonably withhold or unreasonably delay. In the
         event that the rent for said portion subleased or sublet shall exceed
         the rent paid to the Lessor, the increment shall be retained by the
         Lessee.

L. ENVIRONMENTAL - 21E -Etc.

     1.  The parties are aware that the site upon which the facilities are
         located has been under review by the Department of Environmental
         Protection ("DEP"); and that the former occupant, GENERAL ELECTRIC
         COMPANY ("G.E."), was named the responsible party in a Notice of
         Responsibility dated June 11, 1986. Subsequently, the Lessor received a
         Notice of Responsibility ("N.O.R.") from DEP dated April 16, 1991
         occasioned by bankruptcy proceeding instituted by the parent company of
         Converse, Inc. (Sublessee of G.E. of Building No.2.)

     2.  The contamination of the site resulted from releases of gasoline, oil
         and other substances by G.E. and its sub-lessee, Converse, Inc.

     3.  G.E. accepted and assumed the responsibility to conduct remediation
         activities in accordance with plans submitted to, and approved by, D.
         E. P. (including matters referred to in the N.O.R mailed to the Lessor
         dated, as stated, April 16, 1991 and occasioned by the bankruptcy
         proceedings aforesaid).This responsibility has been expressly
         acknowledged and assumed by the successors to G.E., i.e., MARTIN
         MARIETTA CORPORATION and its successor, LOCKHEED MARTIN CORPORATION
         ("LOCKHEED").

         LOCKHEED is committed to (and is engaged in) the necessary remediation
         process as approved by, and under the oversight of, D. E. P.

     4.  Lessor will seek reports of the engineers engaged by LOCKHEED. These,
         as well as

                                      10
<PAGE>
 
         progress reports relating to the remediation activities as received by
         the Lessor, shall be submitted by the Lessor to the Lessee.

     5.  LESSOR shall indemnify the Lessee from any claims arising out of any
         contamination of the site that has occurred prior to the occupancy of
         the leased premises by the Lessee; with the understanding that in the
         event any such claims shall arise, the Lessor shall make claim in
         respect thereto against the responsible party or parties (see above).
         Accordingly, in the event that any such claim shall arise, the Lessor
         with the cooperation of the Lessee, shall require intervention of, and
         indemnification from, the responsible party or parties, as above set
         forth, against any damages resulting from said claims. The Lessor and
         the Lessee shall consult and to co-operate with each other in the event
         that any such claims shall arise.

     6.  The parties acknowledge that the Lessor is currently engaged in
         negotiations with LOCKHEED with respect to the continuing
         responsibility of LOCKHEED (subject to the oversight of the D. E. P.)
         and to confirm and define liability, indemnification and the nature of
         related documentation and agreements that may be agreed upon. Lessee
         agrees to cooperate with respect thereto if requested in order that
         remediation activities shall continue and be facilitated to further the
         best interests of the parties.

M. EASEMENTS AND RIGHTS OF ACCESS

     Lessor shall retain existing easements and rights of way over the

     perform work upon, and to service, water and fire protection facilities and
     lines, Waste Water Treatment Facility, and for any other purpose required
     by the Lessor. Easements and rights of access have been granted for this
     purpose to AMETEK, as successor to G. E. Further, Lessor retains, and shall
     have, the right to grant easements in connection with said management and
     oversight (including easements to LOCKHEED MARTIN CORPORATION in order to
     facilitate its remediation of the site as required by D. E. P. - See
     Section L hereof).

     Said easements and rights of access shall not unreasonably interfere with
     the business activities of the Lessee.

N. WASTE WATER TREATMENT FACILITY

   1.  Said Building No.2 is serviced by a new and "state of the art" waste

       of its operation and ordinary maintenance. Said costs shall be shared
       with the other tenant of the facilities, AMETEK AEROSPACE PRODUCTS, INC.
       (AMETEK); provided only, however, that in the event a replacement of the
       said facility (beyond maintenance and operation) the tenants using same
       shall be responsible for said replacement and shall contribute thereto
       upon the agreed upon formula.

       During the first ten (10) years of the term of the lease, however, Lessee
       shall have no responsibility with respect to replacement of the facility.



   3.  In the event that there shall be any damage, dysfunction or loss to the
       said Waster Water Treatment facility caused by any use, activities or
       misuse by the Lessee or any of its personnel, representatives or
       employees, the Lessee shall indemnify the Lessor with respect to said
       damage, dysfunction or loss and shall make the necessary payments to
       rectify said damage, dysfunction or loss

   4.  Lessee will pay that share of the real estate or other taxes assessed
       against said Waste Water Treatment Facility (in the event that any shall

              expansion to Building No.2 referred to in Section H above
              ("POSSIBLE EXPANSION") and seek preliminary opinion as to its
              feasibility.

Q. MISCELLANEOUS

   MATTERS OF CONCERN TO AMETEK (TO BE ADDRESSED):

     1   Fire sprinklers - Ametek wishes connections to both P.1.V.'s be
         severed; with new feed line from street. (To avoid activating
         sprinklers, merely closing valves is not sufficient.)

     2   Ametek requires that the fire tank suppression system remain part of
         its sprinkler system. Requires natural gas feed from Building No.2.

     3   All shared electrical feeds to be segregated and metered separately.
         (Current underground feed to Building No.2 must be removed from main
         switch gear.)

     4.. Glass tunnel - connector. (AMETEK would like to discuss this)

     5.  Delineation of property lines (AMETEK would like to discuss this)

     6   Parking:

         (a) Shared parking between buildings;
         (b) Parking spaces pertaining to AMETEK and to Scanning should be
             differentiated with different colored lines.
         (c) Parking lot lighting is already separated and segregated.

     7.  AMETEK has closed the entrance from Concord Street to afford extra
         protection to parked vehicles. It will be kept open if General Scanning
         so requires.

     8.  AMETEK has a federal EPA permit to discharge non-contact cooling water
         through outsell. If General Scanning wishes to utilize this outsell for
         similar purposes, AMETEK must be informed so that request for a new
         permit may be filed.

     9.  Snow removal and Landscaping

                                      13
<PAGE>
 
          AMETEK wishes to discuss arrangement for the service with General
          Scanning

      10. AMETEK will provide around-the-clock security for its facilities.
          General Scanning must provide security for its own facilities.

      11. Insurance.

or other withdrawals from the Policy to the extent, and only to the extent, of

Employer under the Policy and not reimbursed by the Employee as provided in
Section 3(a). The interest due on such loans or withdrawals shall be a debt of
the Employee to the Insurer.

     (b)  The Employer reserves the right at any time to obtain policy loans or
other withdrawals from the Policy to the extent, and only to the extent, of the
aggregate premium payments made by the Employer under the Policy and not
reimbursed by the Employee as provided in Section 3(a). The interest due on such
loans or withdrawals shall be a debt of the Employer to the Insurer.

     (c)  Each of the Employer and the Employee may assign its interest in the
Policy as collateral for any loans or withdrawals that it is permitted to make
under this Section 4.

     5.   DEATH BENEFIT.

     (a)  The Policy's death benefit shall be divided as follows: (i) one half
of the total death benefit shall be paid to the beneficiary designated by the
Employee in the manner and in the amounts provided in the beneficiary
designation provision of the Policy, and (ii) one half of the total death
benefit shall be paid to the Employer. The Employee shall have the sole and
exclusive right to designate and change the beneficiary for his share of the
Policy death benefit.

     (b)  Promptly after the Employer receives notice of the death of the
Employee, the Employer shall take such actions as may be necessary to cause the
Insurer to pay the Policy's death benefits to the parties entitled thereto under
Section 5(a).

the provisions hereof and, in the event of any inconsistency, the provisions of

     (d)  The death benefit payable to the Employer shall be reduced by any
amounts deductible from the Policy death benefit in respect of any outstanding
loans or withdrawals by the Employer.  The death benefit payable to the
beneficiary of the Employee shall be reduced by any amounts deductible from the
Policy death benefit in respect of any outstanding loans or withdrawals by the
Employee.  In the event any outstanding loans or withdrawals by the Employee
reduce the death benefit to the Employer, the estate of the Employee shall
reimburse the Employer for the amount of any such reduction.

     (e)  Each of the Employer and the Employee shall have the sole and
exclusive right to exercise any optional mode of settlement permitted by the
Policy with respect to its respective share of the Policy death benefit.

shall deliver the policy to the Employee. The party in possession of the policy
shall from time to time upon request make the Policy available for inspection
and copying by the other party.

all premiums to the Insurer when due. The Employee, or any beneficiary or
beneficiaries of his, may file a request for benefits with the Plan
administrator.  If a claim request is wholly or partially denied, the Plan
administrator shall furnish to the claimant with a notice of its decision within
sixty (60) days in writing, and in a manner to be understood the by claimant,

            denial is based;

     (iii)  a description of any additional material or information necessary

            such material or information is necessary; and

            steps to be taken by a claimant who wishes to submit his claim for
            his review.

     (b)    A claimant or his authorized representative may, with respect to any
denied claim request a review upon written application filed within thirty (30)
days after receipt by the claimant of written notice of the denial of his claim;
review pertinent documents; and submit issues and comments in writing.

     (c)    Any request or submission shall be in writing and shall be directed
to the Plan administrator. The Plan administrator shall have the sole
responsibility for the review of any denied claim and shall take all appropriate
steps in light of its findings. The Plan administrator shall render a decision
upon review of a denied claim within thirty (30) days after receipt of a request
for review. If special circumstances warrant additional time, the decision shall
be rendered as soon as possible, but not later than ninety (90) days after
receipt of request for review. Written notice of any such extension shall be in
writing and shall include specific reasons for the decision written in a manner
to be understood by claimant, as well as the specific references of the
pertinent provisions of the Plan on which the decision is based. If the decision
on review is not furnished to the claimant within the time limits described

make such changes to the Plan as it deems necessary and appropriate subject to
the limitations of Section 2(b).
