Item 1.  Business

                                   THE COMPANY

     Zygo Corporation designs, develops, manufactures and markets high
performance noncontact electro-optical measuring instruments, systems and
accessories, and optical components to precise tolerances both for sale and for
use as key elements in its own products. Utilizing proprietary laser and optical
technology combined with advanced software and electronics, Zygo's precision
noncontact measuring instruments and systems enable manufacturers in a variety
of industries, including data storage, semiconductor, and precision optics, to
increase operating efficiencies and production yields by identifying and
collecting quantitative data on product defects, both during and after the
manufacturing process. Zygo's optical components are used in many applications,
including laser fusion research, semiconductor manufacturing equipment, and
aerospace optical systems, as well as being an integral part of precision
optical instruments.

     Predominantly all of Zygo's instruments and systems employ either a laser
or white light source to make noncontact measurements. Through a process called
interferometry, a pattern of bright and dark lines (called fringes) results from
an optical path difference between a reference and a measurement beam. Zygo's
products then analyze these patterns through a series of steps and generate
quantitative three-dimensional surface profiles, which are used to determine
conformity to dimensional specification and, increasingly, to analyze and
enhance manufacturing processes. Interferometric measurement instruments and
systems are used by a variety of industries, including by the data storage
industry to inspect and analyze the surface of computer hard disks and
read/write heads, and by the semiconductor industry for high precision distance
measurement and motion control.

                                   BACKGROUND

     Historically, measurement and inspection instrumentation has consisted of
contact profiling devices and visual qualitative inspection systems. Advancing
technologies have required manufacturers in a variety of industries to produce
smaller products with more precise tolerances and decreased design geometries,
not capable of adequately being measured by the devices and systems then being
utilized. For example, contact profilers and visual qualitative inspection
systems are inadequate for quantitative analysis of critical dimensions such as
air bearing surface geometry and pole-tip recession necessary in high volume
production of read/write heads.

     The demands on these manufacturers to produce more powerful and smaller
products with more precise tolerances have fueled demand for precision
noncontact measuring instruments. In fact, high performance, noncontact
metrology is an enabling technology for the semiconductor, data storage, and
other vital high technology industries. The trend towards miniaturization and
tighter tolerances creates new challenges for manufacturers as they are forced
to handle, measure, and test ever smaller components. As piece part dimensions
and tolerances become smaller, "nano technology scale" precision is
necessitated. Disk drive manufacturers, for example, continue to increase drive
capacity while reducing the size of drives. For this to happen, the recording
head must fly closer to the disk and the head itself must be made smaller and to
greater precision.

     In addition, until recently, noncontact measuring instruments have been
limited almost exclusively to use by quality control laboratories for off-line
inspection on a test basis only. The historical cyclical nature of the
semiconductor industry, the data storage industry, and other capital goods
sector industries, together with increased competitive forces in these
industries, have forced these industries to no longer depend solely on sales
growth to fuel financial performance improvement, but rather to focus greater
attention on the need to reduce production defects and significantly increase
production yields. These pressures on manufacturers to improve productivity and
quality have required integration of process control technologies directly into
the manufacturing process, allowing manufacturers to test a greater percentage
of their components while in production.

                                       3


Instrumentation is increasingly being sought to more accurately measure the
conformity of parts to their specifications and detect defects directly on the
manufacturing line, and to address other specific needs of the manufacturers to
improve production yields. As the data storage industry, semiconductor industry,
and other high technology industries are forced to install more sophisticated
and difficult to manage and control production and assembly processes, a greater
degree of on-line, high precision, surface metrology and defect detection
systems is required.

                                THE ZYGO SOLUTION

     Zygo introduced its first interferometer in 1972. All of Zygo's instruments
and systems utilize interferometry to accomplish precise measurement of a
variety of surface geometries or to control motion and minute movements during
the manufacturing process. In interferometry, a pattern of bright and dark lines
(fringes) results from an optical path difference between a reference and a
measurement beam. Incoming light is split inside an interferometer, one beam
going to an internal reference surface and the other to a sample. After
reflection, the beams recombine inside the interferometer, undergo constructive
and destructive interference, and produce the light and dark fringe pattern. The
number, shape, and position of the lines in the fringe patterns can be analyzed
to provide quantitative surface structure analysis. Zygo's interferometric
instruments and systems utilize highly sophisticated subsystems, including:
precision optical components such as beamsplitters, reference optics, and
transmission optics; stable and long-life laser or other light sources; piece
part positioning stages; high-powered workstations or PCs for processing and
analyzing fringe pattern data; and a variety of peripheral components such as
monitors and printers.

     Interferometry has certain inherent benefits over other forms of surface
and distance measurement as it provides noncontact, quantitative, full field of
view, ultra-high resolution surface analysis in three dimensions, which results
in higher analysis throughput and lower cost of ownership for the user.
Additionally, interferometric metrology is often an enabling technology as
dimensions and tolerances of many parts in high technology applications have
dimensions below 250 nanometers.

     Zygo's instruments and systems provide critical productivity enhancement
capability to the data storage, semiconductor, and other high technology
markets. Zygo has worked closely with leaders of the data storage,
semiconductor, and other capital goods sector industries to help these
manufacturers meet the ever-increasing production demands of their industries.
Utilizing proprietary laser and optical technology combined with advanced
software and electronics, Zygo's precision noncontact measuring instruments and
systems enable manufacturers in a variety of industries to increase operating
efficiencies and product yields by identifying and collecting quantitative data
on product defects, both during and after the manufacturing process.

     A wide range of operational features and data analysis capabilities are
available on Zygo's measurement instruments. Instrumentation has been designed
with maximum flexibility to satisfy a customer's existing needs and to be
adaptable to satisfy expansion and growth. Certain measuring devices can be used
in either the horizontal or vertical configuration, and on the production line
or in the development lab.

     To meet the rapidly changing and increasing requirements of manufacturers,
Zygo's business is transforming from that of an off-line quality control and
quality assurance test and measurement instrument supplier to an on-line
production improvement and yield management system provider. For example, Zygo's
Automated Air Bearing Surface Analysis System measures the air bearing surface
geometry of read/write heads in-line as the heads are being manufactured. The
system performs quantitative measurements on seven critical read/write head
parameters with a throughput of up to 20,000 heads per day and provides
real-time critical data to the manufacturing process control center to make
on-line production process changes, thereby reducing the number of defective
heads manufactured. Zygo recognized another opportunity for yield improvement in
the data storage industry in flying height testing. Early in calendar 1995, Zygo
formed a division in Simi Valley, California, to develop products for that
industry with its first undertaking being focused on the flying height tester.
Together with Zygo's engineers in Middlefield, Connecticut, the team developed a
production flying height tester and introduced the product in September 1995;
shipments of the Pegasus 2000 flying height tester commenced in May 1996. The
Pegasus 2000 addresses one of the 

<PAGE>
                                       4


data storage industry's most critical requirements, the ability to measure
flying height at near contact. Another example of Zygo's instruments and systems
which allows its customers to enhance productivity and improve production yield
is the ZMI-1000, used by semiconductor manufacturers within their
photolithography systems to precisely control the movement of the systems' x/y
stage to a precision of one nanometer. As product geometries and tolerances
reduce and yield improvement becomes increasingly important, new opportunities
are continuously being explored.

                                  ZYGO STRATEGY

     Zygo's objective is to expand its position as a leading worldwide supplier
of high performance, noncontact electro-optical measuring, production control,
and yield management improvement instruments, systems and accessories that
improve the performance, quality, reliability, yield and cost of automated
manufacturing processes, and of optical components to precise tolerances. Zygo
dedicates substantial resources to research and product development to enable it
to compete effectively in its market areas.

     Key elements of Zygo's strategy include:

     Maintain Enhanced Leadership Through Innovative Technical Solutions. By
     integrating its proprietary electro-optical technologies, proprietary
     applications software and unique system integration capabilities, Zygo
     provides leading edge automated optical inspection solutions in the
     shortest possible time. Zygo's core technologies of optical interferometry,
     optical metrology, system engineering integration, application software,
     and precision optical component fabrication and coating are directly
     applied to meet the higher measurement precision, accuracy, resolution,
     data acquisition and data analysis requirements in the most demanding
     manufacturing processes of its customers. Throughout its history, Zygo has
     met its customers' requirements through innovation and invention with 63
     United States patents and 9 foreign patents, and has 13 United States
     patent applications and 3 foreign patent applications pending.

     Focus on New Market Segments. Zygo's products have applications for a wide
     variety of industries. In the development of these products, Zygo focuses
     on market segments which it believes have growth potential and in which
     Zygo can reasonably expect to become a leading manufacturer. Zygo seeks to
     adapt the noncontact inspection and process control technology it develops
     for one application to other markets.

     Broaden Customer Relationships. Zygo focuses on establishing the strongest
     relationship with major industry leaders in its served markets. This is
     accomplished by working closely with its customers and identifying
     increasing numbers of applications for automated optical inspection and
     yield improvement systems. Zygo also focuses on fully integrating its
     offerings into its customers' manufacturing processes through automated
     parts handling, enhanced product metrology and defect analysis, and by more
     complete integration into the customers' workcells by fully integrated
     process information networking, all geared to improve production. Zygo
     intends, by forming closer customer alliances, to better understand the
     evolving needs of its customers and, through the application of innovative
     technology, to provide high performance, high quality, cost effective
     solutions to the production improvement requirements in the shortest
     possible cycle time. Through this solution-sales cycle, which further
     promotes a closer and longer term partnership relationship between Zygo and
     its customers, Zygo intends to attain a preferred position with major
     industry leaders.

     Supply Quality Solutions Rapidly. Zygo seeks to deliver high quality and
     high reliability system solutions in a minimal cycle time. To this end,
     Zygo has installed an enterprise-wide total quality process where
     employee-led teams work to continuously improve the effectiveness and
     efficiency of its processes while searching out and removing areas of poor
     quality and waste. Zygo's operations strategy focuses on internally
     providing those 

<PAGE>
                                       5


     manufacturing services that add unique value in a rapidly changing customer
     needs environment.

     Provide Uninterrupted Worldwide Service and Support. To support leading
     customers' continuous manufacturing processes, Zygo ensures optimal
     operation and reliable performance of its production control equipment
     through its worldwide customer support service group. Through a worldwide
     network of service representatives, Zygo provides 24-hour on-demand
     maintenance services. Its service engineers have a unique skill set,
     including optical and electrical component repair, software, application
     and system integration diagnostic and problem solution capabilities.

     Broaden Product Offerings and Markets Through Internal Developments and
     Acquisitions. Zygo intends to broaden its product offerings by continuing
     to internally develop additional products and by aggressively pursuing the
     acquisition of companies where synergies can be identified. In 1995, Zygo
     formed a start-up operation in Simi Valley, California, as a way to broaden
     its product offering and participation in the data storage industry. Zygo
     has determined that these start-up operations can be an effective
     alternative to an acquisition when the technology resident in Zygo is
     complementary to the market knowledge and expertise resident in the
     individuals hired to manage the start-up. Zygo also maintains an active
     program of investigating and negotiating potential synergistic acquisitions
     which extend Zygo's product lines or markets. Zygo believes that its
     acquisition strategy is an important element of its total business
     strategy. In 1995, Zygo completed the acquisition of a small manufacturer
     of high precision laser tubes, which allowed Zygo to bring in-house a
     technology that is critical to the performance of its motion control
     products. Subsequent to the close of its fiscal 1996, Zygo completed the
     acquisition of Technical Instrument Company, a manufacturer of confocal
     microscopy systems and modules, and the acquisition of NexStar Automation,
     Inc., a manufacturer of automation and parts handling equipment. (See
     "-Technical Instrument Company Acquisition" and "-NexStar Automation, Inc.
     Acquisition" later in this Form 10-K405.)

                                    PRODUCTS

     Zygo manufactures high performance, noncontract electro-optical measuring
instruments, systems and accessories, and optical components to precise
tolerances both for sale and for use as key elements in its own products. Zygo
operates in a single business segment, electro-optics, and offers products which
fall into two general categories: (1) instruments, systems and accessories, and
(2) precision optical components.

Instruments, Systems and Accessories

     Zygo's product strategy is to develop its instruments and systems utilizing
modular designs where entire product families share several, if not all, of the
same components, modules and software. Since 1992, Zygo has redesigned all of
its instruments and continues to upgrade its software and enhance its products
by adding features such as automated stages and parts handling to many of its
instruments and systems.

     All of Zygo's instrument products utilize powerful processors that
facilitate high speed data acquisition and data analysis. Zygo's interferometric
surface analysis microscopes and large aperture surface measurement
interferometers utilize Zygo's proprietary MetroPro(R) software, which has a
graphical user interface that makes the product very user friendly. The
MetroPro(R) software, combined with super high-resolution graphics and pull-down
menus, provides the user with engineering solutions without off-line processing.
The software allows the user to record, print, and store measurement data
locally as well as to distribute the data through networks for process
management and further analysis. Zygo's proprietary software provides Zygo with
comparative

advantage because of its high speed, powerful analysis capability based on
proprietary algorithms, easily configurable screens, powerful image analysis
modules, and adaptability to new applications.

     The surface characteristics of many products in industries such as
semiconductor, data storage, fiber optics, and medical implants, and with
increased applications in the paper, printing plates, coatings, and
pharmaceuticals industries, controls the performance of the product. As a
result, surface structure analysis is fundamental to many facets of research and
industry. The Zygo Maxim*GP, the fully automated AAB System, and NewView 100
microscopes combine advanced techniques of interferometry, microscopy, and
precision translation stages, to enable high precision surface analysis. Unlike
visual microscopes, Zygo's instruments provide measurement information as
quantitative three-dimensional images, two- and three-dimensional surface maps
with colors and shades representing relative heights of surface features, and
numeric results. The Maxim*GP is based on phase shifting interferometry to
provide very precise, fast measurements of specular ("Mirror-like") or near
specular surfaces. The NewView 100 uses scanning white light interferometry to
measure nonspecular surfaces.

     Zygo's interferometers for large surface measurement, the Growth Potential
Interferometer ("GPI") family of upgradable instruments, basically consist of
enlarged versions of the three-dimensional microscope, designed to perform
surface profile analysis on larger surface areas. Each member of the GPI
interferometer family is designed to address a specific level of measurement
needs. While all GPI models have essentially the same purpose - noncontact
measurement of flat or spherical surfaces and transmitted wavefront measurement
of optics - they differ widely in operational features and data analysis
capabilities. The GPI family of products is used extensively in the optics
industry to measure glass or plastic optical components like flats, lenses and
prisms, and more recently in a growing number of other situations to measure
precision components such as hard disks, bearing and sealing surfaces, polished
ceramics, and contact lens molds.

     In September 1995, Zygo introduced the Pegasus 2000, a flying height
tester. The flying height tester measures the height at which a read/write head
flies over the surface of a magnetic disk within the disk drive. The industry
demands for increased storage capacity are compelling manufacturers to reduce
the flying height, as increased amounts of data can be stored on magnetic heads
the closer they fly to the disk. The Pegasus 2000 offers several unique
capabilities to the data storage industry. As flying heights are reduced,
manufacturers require measurement instruments which can measure at near-contact.
Zygo's flying height tester actually increases in accuracy the closer the
read/write head flies over the surface of the disk. Additionally, due to
significant increases in disk storage requirements, manufacturers require
easy-to-use, high throughput testers. The Pegasus 2000 has been designed as a
production oriented tester. For example, the system is capable of having a head
loaded while a second head is being tested. Also, the tester automatically
calibrates the sensor requirements of each head rather than requiring operator
inputs. Zygo commenced shipments of its Pegasus 2000 in May 1996.

     Fast, precise control of machine motion is the primary challenge in many
production processes. Industries as diverse as semiconductor and flat panel
display production and optical component manufacturing require systems to
measure the position of a tool relative to a part under fabrication. Zygo's
ZMI-1000 Laser Interferometer system provides the measurements that control the
position of some of the world's most sophisticated machinery. Through the use of
a directed laser beam reflecting from the moving portion of the machine, the
ZMI-1000 can tell the machine's computer control systems about movements as
small as 1.24 nanometers (billionths of a meter). This level of accuracy can be
compared to the finest geometries of semiconductors, which are approximately 350
nanometers. Its design also accommodates fast motions and maintains its
precision at speeds in excess of a meter per second. Applications for these
interferometers include accurately measuring and controlling, while they are in
motion, the x, y, and theta stages in photolithography equipment that is used in
making semiconductors and flat-panel video displays. Although Zygo sells this
instrumentation to a large number of customers, the majority of these
interferometers are sold on an OEM basis to Canon. Zygo is Canon's sole-source
provider of motion control devices for use in Canon's photolithography systems.
These systems perform a critical function in the process of manufacturing
semiconductors.

     Zygo believes it is a world leader in the design and manufacture of highly
accurate "cosmetically excellent" surfaces and angles on plano components
ranging in size from small prisms to large mirrors, scanners, aerospace windows
and laser amplifier disks. Zygo's precision machining

capability is used to make complex glass and ceramic parts such as stage mirrors
and other lightweight structures. Operations at Zygo's state-of-the-art optical
components manufacturing facility include machining, shaping, generating,
grinding, polishing, and edging. Zygo utilizes technology that it has developed
and incorporated into rotary polishing machines designed and built by Zygo.
Zygo's thin film coating capability includes metallic and high-efficiency
dielectric coatings for transmissive or reflective applications, in the
ultraviolet, visible, and infrared regions of the spectrum. Zygo also applies
polarization, beamsplitter, and anti-reflection coatings.

     To ensure quality control of its products, Zygo maintains complete control
over every facet of manufacturing, from grinding and polishing to mating and
assembly. At each stage of production, opticians test and verify the components
using sophisticated interferometric measuring instruments designed and
manufactured by Zygo. Zygo believes that this vertical integration gives Zygo a
distinct competitive advantage over most of its competitors in the production of
its precision optical components.

Competition

     Although Zygo believes that its products are unique, competitors offer
technologies, instrumentation, and systems that are capable of performing
certain of the functions performed by Zygo's products. Zygo faces competition
from a number of companies in all its markets, some of which have greater
manufacturing and marketing capabilities, and greater financial, technological,
and personnel resources. In addition, Zygo may compete with the internal
development efforts of its current and prospective customers. Zygo believes that
its instrumentation and products offer several advantages over competitive
products in terms of accuracy, speed, flexibility, cost, and ease of use.
Although Zygo has attempted to protect the proprietary nature of such products,
it is possible that any of Zygo's products could be duplicated by other
companies in the same general market. In addition, there can be no assurances
that Zygo would be able to compete with similar products produced by a
competitor.

              PRINCIPAL CUSTOMERS AND OPERATIONS BY GEOGRAPHIC AREA

     The growing need for dimensional control to the subnanometer level has
created a growing need for Zygo's instruments and systems among both OEMs and
end users. Traditionally, Zygo's largest market has been high precision optical
components and systems. As the market demands for greater tolerance control in
the manufacturing process has increased, particularly in the data storage and
semiconductor markets, Zygo has been able to meet these demands with
on-the-production-line process and quality control instruments and systems as
well as with its off-line quality control instruments. As a result, the data
storage and semiconductor industries are now Zygo's largest markets.

     Historically, a relatively limited number of customers have accounted for a
substantial portion of Zygo's revenues. In fiscal years 1996, 1995, and 1994,
sales to Zygo's top two customers accounted for approximately 53.8%, 46.8%, and
41.2%, respectively, of Zygo's net sales. During these fiscal years, sales to
Canon, Zygo's largest customer, accounted for approximately 36.9%,

<PAGE>
                                       9


29.6%, and 32.1 %, respectively, of Zygo's net sales. Canon, one of the original
investors in Zygo, is a valuable strategic partner of Zygo and the relationship
is important to both companies for many reasons. Sales to Canon include products
that Canon uses in its manufacturing facilities, such as Zygo's large aperture
surface measurement interferometers, which are used to quantitatively analyze
the surface of optics Canon produces for its photolithographic steppers, and
Zygo's motion measurement components and systems which are incorporated into
Canon's steppers for controlling the x/y stage in that product. Zygo is Canon's
sole source for motion control systems. Sales to Canon also include optical
components and instruments, systems and accessories sold by Canon as Zygo's sole
distributor in Japan. In fiscal 1996 and 1995, Seagate, a leading manufacturer
of computer disk drives and related hardware and software, accounted for an
additional approximately 16.8% and 17.2%, respectively, of Zygo's net sales;
sales to Seagate were insignificant in fiscal 1994. No other customer accounted
for greater than approximately 10% of Zygo's net sales in fiscal 1996, 1995, or
1994.

     The following is a representative list of end users of Zygo's products:

     Zygo sells its products worldwide through a combination of direct sales
staff and independent distributors and sales representatives. Zygo maintains a
direct sales staff of three persons at its headquarters in Middlefield,
Connecticut, one person in Atlanta, Georgia, one person in Fort Collins,
Colorado, one person in Mesa, Arizona, and one person in Santa Clara,
California, for domestic sales. International sales are made through more than
10 representatives and distributors, covering sales and service in 20 countries
including Japan, Singapore, Malaysia, South Korea, Taiwan, Philippines, United
Kingdom, Germany, Italy, and France.

     The following table sets forth the percentage of Zygo's total sales
(including sales delivered through distributors) by location during the past

     Substantially all of Zygo's export sales are negotiated, invoiced, and paid
in United States dollars. International sales and foreign operations are subject
to certain inherent risks.

     The selling process for Zygo's products frequently involves participation
by sales, marketing, applications specialists, and engineering personnel. Zygo's
marketing activities also include participation in international standards
organizations, trade shows, publication of articles in trade journals,
participation in industry forums, and distribution of sales literature. In
addition, Zygo's strategic relationships with customers serve as highly visible
references.

     Zygo believes that its strong commitment to service is essential, based on
the growing complexity of the equipment used in the manufacturing process by
Zygo's customers. At June 30, 1996, Zygo's customer support and service staff
consisted of 14 persons. In addition, Zygo's distributors and sales
representatives offer a worldwide network for customer support, providing
24-hour on-demand maintenance services. The service engineers are skilled in
optical and electrical component repair, software, application and system
integration, diagnostic and problem solving capabilities. Zygo also offers
training programs and maintenance contracts for its customers.

                                     BACKLOG

     The Company's backlog at June 30, 1996 and 1995, was approximately $19.1
million and $12.9 million, respectively. The significant increase from the prior
year end resulted primarily from stronger demand for all of the Company's
electro-optical instruments and accessories. The backlog of the Company's
electro-optical instruments and accessories at June 30, 1996, increased
$5,321,000 (58%) from that at June 30, 1995. The backlog of the Company's
precision custom optical components increased by $833,000 (22%) from the year
earlier as a result of improved demand for precision optical components.
Substantially all of the backlog as of June 30, 1996, is expected to be shipped
in fiscal year 1997. Historically, cancellation or reduction of orders has not
had a significant impact on the Company's results of operations.

                         RESEARCH AND DEVELOPMENT COSTS

     Information regarding the Company's research and development costs is set
forth in the Consolidated Statements of Earnings on page 14 of the Company's
1996 Annual Report, which statements are herein incorporated by reference. Zygo
operates in an industry that is subject to rapid technological change and
engineering innovation. Zygo distinguishes its instrument products on the basis
of its unique electro-optical sensor technology, its software capability, and
its skill in systems integration. Because Zygo believes that its ability to
compete effectively with its instruments and systems in its markets depends in
part on maintaining its expertise in applying new technologies and developing
new products, Zygo dedicates substantial resources to research and development.
At June 30, 1996, Zygo employed 42 individuals within its R&D operations,
including 16 individuals with advanced degrees of which six individuals have
earned doctoral degrees. During the second half of fiscal 1995, Zygo formed an
R&D facility in Simi Valley, California, for the purpose of developing test and
measurement instruments for the disk drive industry. The first such product
development effort at the new facility focused on flying height testing and, in
conjunction with Zygo's engineers in the Middlefield, Connecticut, facility,
produced Zygo's Pegasus 2000 flying height tester. See "-Products." In addition,
as an integral part of Zygo's product development strategy, Zygo has formed
technical relationships with several customers. Zygo's strategy is to form close
technical working relationships with the leading suppliers in its markets and
thereby develop products and systems which have the greatest relevancy to the
marketplace in general. In connection with its R&D operations, Zygo also
maintains a close working relationship with various research groups and academic
institutions in the United States as well as abroad.

     Zygo believes that continued enhancement, development, and
commercialization of new and existing products and systems is essential to
maintaining and improving its leadership position. Zygo intends to direct its
research and development activities in several different areas. For example,
Zygo continues to seek to develop products that have greater measurement range
and precision to address new markets. Additionally, Zygo intends to continue to
add products that are automated in-process 

<PAGE>
                                       11


instruments and systems. There can be no assurance that these efforts or any
other product development efforts of Zygo will be successful in producing
products that respond to technological changes or new products introduced by
others.

                         PATENTS, LICENSES, TRADEMARKS,
                           AND PROPRIETARY INFORMATION

     Zygo relies on a combination of patent, copyright, trademark, and trade
secret laws and license agreements to establish and protect its proprietary
rights in its products. Zygo believes, however, that its success depends to a
greater extent upon innovation, technological expertise, and distribution
strength. Zygo requires each of its employees to enter into standard agreements
pursuant to which the employee agrees to keep confidential all proprietary
information of Zygo and to assign to Zygo all rights in any proprietary
information or technology made or contributed by the employee during his or her
employment or made thereafter as a result of any inventions conceived or work
done during such employment. Despite these precautions, it may be possible for a
third party to copy or otherwise obtain and use Zygo's products or technology
without authorization or to develop similar technology independently. In
addition, effective patent, copyright and trade secret protection may be
unavailable or limited in certain foreign countries.

     Zygo has been awarded 63 United States patents and 9 foreign patents since
the Company was founded, and has 13 United States patent applications and 3
foreign patent applications pending. Zygo, the Zygo logo, and Maximo3D are
registered, and the Company also holds several nonregistered trademarks
including Maxim*GP, NewView 100, Growth Potential Interferometer, GPI, ZMI-1000,
Pegasus 2000, and AAB System.

               MANUFACTURING, RAW MATERIALS, AND SOURCES OF SUPPLY

     Zygo's principal manufacturing activities are conducted at its facility in
Middlefield, Connecticut. Zygo maintains a state-of-the-art optical components
manufacturing facility, specializing in the fabrication, polishing and coating
of plano (flat) optics for sales to third parties, as well as the manufacturing
of a wide variety of optics that are used in Zygo's instrument products. Zygo's
manufacturing activities for its instrument products consist primarily of
assembling and testing components and subassemblies some of which are supplied
from within Zygo and others are supplied by third party vendors and then
integrated into Zygo's finished products. Many of the components and
subassemblies are standard products, although certain items are made to Company
specifications. Zygo also maintains Computer Numerical Control (CNC) metal
fabrication equipment for in-house production of strategic metal formed
components.

     Certain components and subassemblies incorporated into Zygo's systems are
obtained from a single source or a limited group of suppliers. Management
routinely monitors single or limited source supply parts, and Zygo endeavors to
ensure that adequate inventory is available to maintain manufacturing schedules
should the supply of any part be interrupted. Although Zygo seeks to reduce its
dependence on sole and limited source suppliers, it has not qualified a second
source for these products and the partial or complete loss of certain of these
sources could have an adverse effect on Zygo's results of operations and damage
customer relationships. To date, the Company has not experienced a significant
production delay from a parts shortage or loss of a single-source component.

     Zygo also maintains a state-of-the-art fully integrated management
information system which includes all business modules (capacity planning,
materials requirements planning, order entry, financials, etc.) necessary to
manage Zygo's growing operations.

                                    EMPLOYEES

     At fiscal year end, Zygo employed 245 men and women, including 140 in
manufacturing, 42 in research and development, 22 in sales and marketing, and 14
in customer service. To date, Zygo has been successful in attracting and
retaining qualified technical personnel, although there can be no assurance that
this success will continue. None of Zygo's employees are covered by collective

<PAGE>
                                       12


bargaining agreements or are members of a union. Zygo has never experienced a
work stoppage and believes that its relations with its employees are excellent.

                                SUBSEQUENT EVENTS

     Subsequent to the close of its fiscal 1996, Zygo completed the acquisition
of Technical Instrument Company, a manufacturer of confocal microscopy systems
and modules, and the acquisition of NexStar Automation, Inc., a manufacturer of
automation and parts handling equipment. A brief description of these businesses
follows:

Technical Instrument Company Acquisition

     Effective as of August 8, 1996, Zygo completed its acquisition of the
Proprietary Products Division of Technical Instrument Company ("TIC"). Prior to
the acquisition, TIC was engaged in two businesses: the proprietary products
division which designs, develops, manufactures, markets, and sells microscopy
systems and subsystems, or modules, and a distribution division which acts as a
sales representative for other firms' products. The distribution division was
spun off into a new company, Technical Instruments - San Francisco, prior to the
completion of the acquisition of the TIC stock by Zygo. An effective purchase
price of approximately $14.7 million was paid, of which approximately $11.7
million was paid in cash and the balance was paid by the issuance of
unregistered shares of Zygo Common Stock.

     TIC, located in Sunnyvale, California, designs, develops, manufactures,
markets, and sells microscopy systems and subsystems, or modules to a variety of
industries, including manufacturers of photomasks used in semiconductor and flat
panel display manufacturing, manufacturers of components for the data storage
industry, biomedical research and other high technology manufacturing and
research applications. The majority of TIC's microscope systems and subsystems
employ white light confocal scanning optical microscopy ("CSOM") technology.
Over the past several years, TIC has added other imaging systems to its product
offering, including laser scanning confocal and atomic force microscopy. Today
TIC specializes in integrating imaging modes, viewing accessories, and
measurement tools within its microscopy systems and subsystems for customers in
a wide variety of high technology fields.

     CSOM is a key base technology employed in TIC's products. The majority of
TIC's microscope systems and subsystems employ white light CSOM technology. In a
microscope utilizing white light CSOM imaging, a high-intensity white light
illuminates a section of a spinning disk containing pinholes arranged in
multiple spiral patterns. Acting as point illumination sources, the pinholes
direct light to points on the sample. The reflected light from the sample
returns through the same section of the disk. Only light from points on the
sample near the focal plane will pass through the pinholes for imaging. The
advantage of the white light CSOM technology over other forms of imaging systems
offering sub-micron definition include: high resolution in real time with no
delay for image processing, transverse resolution, and extremely shallow
depth-of-field provide precise imaging of sub-half micron structures and lower
cost of ownership. CSOM imaging is used for both inspection and metrology
measurement in TIC's systems. A laser confocal system employs a laser light
source which causes a sample to fluoresce with the resulting light of a shorter
wavelength which retraces its path to a pinhole. The fluorescent light is split
into two spectral ranges. After an x/y scan the two channels are digitized and
stored in the computer as separate images that can be displayed individually or
overlaid to create a single color image. This results in high resolution and the
ability to display many layers of translucent samples as a live overlay of
bright, perfectly registered optical sections. Atomic force microscopy measures
the atomic and molecular forces between a sample and an ultra-fine silicon tip
mounted on a spring-loaded cantilever. A laser light is focused on the
cantilever and measured by a position sensitive detector which converts
cantilever deflection into an electrical signal. By keeping the deflection of
the cantilever constant, a sensor scans the sample and measures its compensative
movement. With no electrical conductivity requirement, virtually any sample can
be examined in life size with superior image at fine resolution.

                                       13


     TIC's product strategy has been to develop microscope systems and modules
which leverage the CSOM technology and thereby offer the customer a lower cost
higher capability solution. TIC's products fall into two broad categories:
confocal microscope systems for photomask and wafer metrology and inspection,
and confocal modules sold to OEMs for incorporation into their microscopy
systems.

     TIC's AMS and KMS microscope systems represent the majority of its sales.
The KMS group of products are fully automated high-throughput confocal
microscopy systems which provide measurement in three axes and real-time
observation in color. Nondestructive confocal white light imaging permits
measurements which are impossible with other types of critical dimension
measurement instrumentation such as scanning electron microscopes. Positioning,
measurement, and data collection are easily custom-configured and interface to
most networks. the KMS products utilize powerful software which is menu and
script-file driven to allow for ease in program generation. The AMS product is a
manual version of the KMS which is typically used in development centers for low
volume metrology and inspection requirements. The majority of these products is
sold to manufacturers to optically transfer these images onto semiconductor
wafers. As the demands for finer line width geometry's increases, mask
manufacturers must utilize sophisticated metrology and inspection tools as a way
to improve their manufacturing yields. TIC has focused significant effort on
this market and currently has units installed at all of the market leaders
including: Intel, Photronics, IBM, DuPont PhotoMasks, Inc., Motorola, Fujitsu,
Lucent Technologies (AT&T), ETEC, Hewlett Packard, and Hyundai. TIC believes it
has a dominant position in the mask metrology market where its primary
competition is from the higher cost products manufactured by SiScan and Leica.
TIC's systems are also finding growing acceptance in the metrology measurement
and inspection of thin film read/write heads which are integral components in
disk drives. TIC has delivered systems to several customers in this market
including Read Rite, Applied Magnetics, and Quantum. The AMS and KMS systems
sell for between $260,000 and $500,000 per system depending on the degree of
custom software and accessories provided.

     TIC's module products include the K-2 Industrial module, the NCM module and
the PCM module. The K-2 module provides confocal scanning capability to nearly
any modern upright white-light microscope. The product is fitted to the
microscope as a replacement for the vertical illuminator and attaches to the
microscope stand. The K-2 module provides two confocal modes and one brightfield
imaging mode. TIC also offers an optional confocal software package with the K-2
module which makes it possible to precisely layer several two-dimensional
confocal images to create an extremely accurate three-dimensional image. The K-2
module sells to OEMs for between $10,000 and $30,000 per module. The NCM module
is a confocal module, similar to the K-2 module, which is incorporated into the
Nikon IC-200C microscope. The PCM module was recently developed for an OEM
application in the biomedical field. The module utilizes TIC's laser scanning
confocal technology where fluorescence is used to analyze the subject. This
module, which sells for approximately $30,000, is incorporated into an OEM
product which is used in research work for analyzing cell structures and DNA.
TIC's principal OEM accounts include Nikon, Leica, Reichert, and Nidek.

     TIC sells its products worldwide through a combination of direct sales,
sales agents, and independent distributors. TIC maintains a direct sales and
marketing staff of six persons in Sunnyvale, California. System sales, in the
United States, are handled by a combination of direct sales personnel and
independent sales representatives. OEM sales in the United States are handled by
the direct sales personnel. Sales in Japan, the Pacific Rim, and Europe are
handled through a number of independent agents or distributors. Approximately
40% of TIC's sales are from outside the United States with approximately 60% of
export sales being to Japan and 15% being to the Pacific Rim. TIC supports its
installed base of equipment by maintaining highly trained applications support
and service support personnel. At June 30, 1996 TIC employed seven such persons.
TIC also offers detailed training in the operation and maintenance of its
systems both at its Sunnyvale headquarters and at customer locations.

     TIC operates in an industry that is subject to rapid technological change.
In addition to maintaining a staff of six highly competent research and
development engineers, TIC maintains relationships with the university community
and private individuals who are experts in the field of 

<PAGE>

microscopy to ensure the latest technological enhancements are being integrated
into its systems and subsystems. Also, by maintaining a strategy of focusing on
the requirements of industry leaders within the markets they serve, TIC is
better able to maintain its leading edge technology, both in terms of the
scientific refinements and in terms of the practical customer application
requirements. TIC holds one patent in its own name. This patent covers the
scanning application of scanning confocal microscopy. TIC also licenses the
technology of white light confocal microscopy from Stanford University. This
patent was co-developed by Stanford University and an individual who is
currently the lead scientist at TIC.

     As of June 30, 1996, TIC employed a total of 56 personnel, including 32 in
manufacturing, six in R&D, six in sales and marketing, and seven in customer
support. None of TIC's employees are covered by a collective bargaining
agreement or are members of any union. TIC has never experienced a work stoppage
and believes its relations with its employees are excellent.

     TIC maintains its headquarters in a leased 20,000-square-foot building
located in a high technology area in Sunnyvale, California.

NexStar Automation, Inc. Acquisition

     Effective as of September 12, 1996, Zygo completed its acquisition of
NexStar Automation, Inc. ("NexStar") which was effected through the distribution
of 250,000 shares of Zygo common stock for all of the outstanding shares of
NexStar. NexStar designs, develops, manufactures, and markets comprehensive
automated system solutions to enable manufacturers in a variety of industries,
including the data storage, semiconductor, and medical disposables industries,
to enhance operational efficiencies and product yields. NexStar's high speed
production solutions reduce downtimes, especially in manufacturing processes
adaptable to the manufacture of multiple products differing in size, features,
and functionality. For example, medical tubing is used in a variety of
applications, each requiring separate features, sizes, and functionality.
NexStar has developed a Medical Tube Coiling system, designed for the automated
production of medical tubing for use in these various applications.

     NexStar's automated solutions integrate its own proprietary mechanical
components and applications software with nonproprietary mechanical, software,
and robotics subsystems produced by third parties. NexStar's automated solutions
also enhance production control to ensure consistent high quality. NexStar's
sophisticated automation products and equipment are utilized in many
applications, including media manufacturing, disk drive assembly, semiconductor
manufacturing, and packaging and assembly applications in medical disposables
production.

     In the data storage market, NexStar's focus has been the development of
automated solutions used in cleanrooms for media handling, disk drive, and disk
cartridge assembly. It has created proprietary components including robotic
arms, parts handling, conveyor systems, and disk stack assemblies. Similar
solutions have been developed for the semiconductor market. In the medical
disposables market, NexStar has manufactured proprietary automated products to
assemble disposables, subassemblies, and medical tube coiling devices with
flexible designs that permit the handling in a sterile environment of various
sizes of corrugated or smooth bore tubing and small diameter catheters and
wires.

     The overall growth in high technology fields such as the data storage and
semiconductor industries, combined with the need of manufacturers in those
industries to produce products that are both smaller and more powerful and have
more precise tolerances, has fueled capital expenditures for on-line automation
equipment such as NexStar manufactures.

     NexStar manufacturers advanced automation systems to load and unload
process equipment, enhance the operation of quality inspection equipment, convey
component parts throughout the factory, and assemble complex products. It is
usual for such systems to be built to stringent environmental requirements such
as cleanroom standards, aseptic medical standards, and for resistance to
corrosive conditions. NexStar products and services fall into four general
categories: (1) process equipment automation, (2) quality inspection
enhancement, (3) material transport, and (4) custom system integration.

     Process equipment automation. NexStar develops systems to automate the
movement of material into and out of process equipment where the automation
system is composed of 

<PAGE>
                                       15


nonproprietary commercially available components and software, and proprietary
NexStar manufactured components and applications software. Products are grouped
in families which share many of the same components and custom produced modules.
Product development in this category begins with an initial system designed to
address a specific customer's requirements, is proven through field experience,
is standardized, and is offered to prospective customers with similar needs.

     All of NexStar's products utilize powerful processors that control the
different operations of the automation system, or workcell, and provide the
customer with manufacturing information on the production process. Workcell
controls include error correcting and recovery routines to maximize productive
time. The system controller, or computer, is designed to transfer workcell
manufacturing level information to the factory's central manufacturing
information and control system. All NexStar products are provided with high
quality, graphical user interfaces that provide operation, maintenance, support
engineering, and management interaction with the system. Workcells are intended
for use on a continuous basis, twenty-four hours per day, three hundred
sixty-five days per year. The time required for preventative maintenance and
error recovery is approximately 1.5% of the operating time.

     Quality inspection enhancement. In two of NexStar's market areas, the data
storage and semiconductor industries, automation of quality inspection systems
has typically lagged behind the automation of process equipment. NexStar has
invested in the design of compact automation solutions for a variety of commonly
used inspection systems, and several of NexStar's largest customers are now
beginning to automate in the quality inspection field. Examples of quality units
likely to be automated in the coming years are inspection and measurement
systems for media surface thickness, flatness, and parameters.

     NexStar believes that as a result of its work it has developed special
expertise in this area of automation, and that its ability to connect customers'
inspection systems to their manufacturing information control systems through
the automation interface, permits NexStar's customers to react more rapidly to
manufacturing problems. This improves both yields and production up-time, and
gives increased performance control over manufacturing operations.

     Material handling. Automation operates more effectively when the movement
of component parts and assembled product is controlled. NexStar offers a variety
of robotics automation systems which integrate internally developed proprietary
hardware and applications software with commercially available conveying
equipment built to customer specifications. In addition, NexStar has designed
and manufactured a conveying system that facilitates the use of different media
size transportation containers, or cassettes, while maintaining the accurate,
predictable positioning of the container and parts at the automated workcell.

     NexStar has also designed a cleanroom grade Automated Storage and Retrieval
System (ASRS), using a fabrication concept believed to be unique in the
industry. The ASRS system and conveyors work with customer product tracing
systems, such as bar code identification, to provide parts storage of in-process
product during critical steps in manufacturing, and movement control of each
product lot. Positive tracking of the product throughout the manufacturing cycle
enables NexStar's customers to eliminate inventory aging problems, reduce
work-in-process inventories, and increase responsiveness to customer needs.

     For the data storage industry, NexStar has designed and produced disk drive
and cartridge assembly systems to assemble various disk drive components. These
systems are typically designed to process a disk hub assembly (DHA) at a rate of
one every seven seconds. NexStar uses its internally developed proprietary end
effector, parts handling and transfer and disk stack systems in these assembly
systems.

     For the medical disposables market, NexStar has developed two technologies
for use in product assembly applications. The Medical Tube Coiler is believed to
be the industry's first automated tube coiling system to operate in-line with
extrusion. The flexible design allows the handling of any size corrugated or
smooth bore tubing, small diameter catheters and wires. The Nebulizer Assembly
System is a cost effective, integrated solution for the automated assembly of a
three-piece nebulizer device. Its rugged, high speed design utilizes optimum
systems integration technologies for easy change over with multiple products.

     Custom Systems. NexStar undertakes projects to design and construct custom
systems to customer performance or process requirements. Before doing so,
NexStar conducts marketing and 

<PAGE>
                                       16


engineering research to determine the future sales potential of the custom
system being converted to a standard product and the usefulness of the
engineering experience to be derived from the project.

     Historically, a limited number of customers has accounted for a substantial
portion of NexStar's revenues. In fiscal 1995, sales to NexStar's top two
customers, Iomega Corporation and Akashic Memories Corporation, accounted for
approximately 27.4% and 50.1%, respectively, of net sales. Continued high levels
of business and sales to these customers are expected to continue through fiscal
1997.

     Customers for NexStar's products in the data storage industry include
Iomega Corporation, Akashic Memories Corporation, Syquest Technology
Corporation, Seagate Technology, Inc., StorMedia Inc., Toshiba America Inc., and
Western Digital Corporation. Semiconductor customer include MEMC Electronics
Inc. In the medical disposables field, customers include Whale Scientific Inc.,
Marquest Medical Products Inc., and Sherwood Medical Corporation.

     The selling process for NexStar's automation products and services
frequently involves participation by sales, marketing, and applications
engineering personnel. NexStar's marketing activities include participation in
trade shows and industry forums, publication of articles in trade journals and
distribution of sales literature. In addition, NexStar's strategic relationships
with its customers create highly visible references.

     NexStar has a strong commitment to service, driven by the growing
complexity of the manufacturing equipment utilized by its customers. NexStar's
customer support staff currently consists of two people. In addition, NexStar
will relocate service people to areas with a significant installed base thereby
improving maintenance response. The service engineers are skilled in electrical
and mechanical component repair, applications software, and system integration,
and have diagnostic and problem solving capabilities. NexStar offers training
programs and maintenance contracts to its customers.

     Because the industries in which NexStar operates are subject to rapid
technological change and engineering innovation, its ability to produce
technologically advanced, high quality factory automation systems is highly
dependent on its maintaining substantial engineering resources. At June 30,
1996, NexStar employed 19 individuals within its engineering organization,
including four with advanced degrees. In addition, there are 20 full-time
contract positions primarily dedicated to engineering and manufacturing.
Substantially all of the research and development is done on a
project-by-project basis, using a team approach. NexStar's strategy is to form
close technical working relationships with the leading suppliers of components
in its markets and thereby develop solutions tailored to customer requirements
and having the greatest potential for standardization and market relevancy.

     NexStar's principal manufacturing activities are carried on from Longmont,
Colorado, where it occupies a leased facility equipped with state-of-the-art
computer controlled metal fabrication equipment. NexStar assembles control
panels and electrical/pneumatic subsystems, and fabricates selected mechanical
components and subassemblies in-house. Some metal parts and subassemblies are
supplied internally while others are obtained from third-party vendors and
integrated into finished products. While the facilities are currently adequate
to meet NexStar's needs, it is expected that additional space will be required.
Whenever possible, more than one supplier is used for specific major components
and subassemblies. Limited source supplied parts are continuously monitored.

     As of June 30, 1996, NexStar employed 56 people, including 11 in
manufacturing and customer service, 19 in engineering, 2 in sales, 4 in
administration, and 20 full-time contract positions primarily dedicated to
engineering and manufacturing. Although to date NexStar has been successful in
attracting and retaining qualified personnel, there can be no assurance that
this will continue. None of NexStar's employees are covered by collective
bargaining agreements or are union members. NexStar has never experienced a work
stoppage and believes that it has excellent relations with its employees.

     Although NexStar has designed and manufactured automated solutions uniquely
adapted to market requirements, there are competitors offering product solutions
that perform similar functions. NexStar is subject to competition from two
distinct sources: (i) direct competition from independent companies; and (ii)
indirect competition from current and prospective clients with in-house
operations attempting to develop effective automation solutions.

     Competing companies are either well-established entities with broad product
lines or small, limited resource companies with highly focused product lines.
The well-established entities in the data storage and semiconductor markets
include Automated Tooling Systems Inc., PRI Automation, Wright Industries Inc.,
Phase Metrics, and Vanguard Automation. In the medical disposables market,
NexStar's competition includes Kuntz Automation, Sortimat, Design Technology
Corporation, and CEI Automation. Competitors in the medical disposables market
are geographically dispersed, indicating more regional competition.

     The remainder of this 10-K405 does not include any information concerning
TIC or NexStar.

Item 2.  Properties

     The Company's principal manufacturing and administrative facility is
located on Laurel Brook Road in Middlefield, Connecticut. The facility consists
of one 100,000-square-foot building on approximately 13 acres. The Company also
owns 30 acres of undeveloped land adjacent to its principal facility.
Additionally, on January 4, 1996, the Company purchased approximately 22 acres
of land adjacent to the Company's facility in Middlefield, Connecticut, which
will facilitate expansion of the Company's buildings and/or parking facilities
in the future.

Item 3.  Legal Proceedings

     On June 29, 1988, Zygo filed suit in the U.S. District Court in Arizona
against WYKO Corporation for patent infringement based on the belief that the
WYKO 6000 interferometer infringed certain patents owned by Zygo. On March 1,
1993, the United States District Court (District of Arizona) rendered a
Memorandum Opinion and Findings of Fact and Conclusions of Law in the matter of
the patent suit. The conclusions of the court were that Zygo's patent is valid,
the WYKO Model 6000 interferometer infringes the Zygo patent, that WYKO
Corporation is liable to Zygo for any damages suffered as a result of WYKO's
infringement of Zygo's patents by making, selling, and using the WYKO Model 6000
interferometer, and that the amount of the monetary judgment and other relief
shall be determined following a trial on the issue of damages. The damage phase
of the trial was held from November 29, 1993 through December 6, 1993. The Court
rendered its judgment on June 2, 1994, awarding Zygo approximately $2.7 million
plus recovery of certain costs to be awarded by the Court which were incurred by
Zygo in connection with the conduct of the trial and entered a permanent
injunction prohibiting further sales of the WYKO Model 6000 interferometers
found to infringe. An appeal of the District Court's decision was filed by WYKO
on August 9, 1994 with the Court of Appeals for the Federal Circuit located in
Washington, D.C. The oral argument of the appeal was heard by the Court of
Appeals on March 9, 1995. On April 1, 1996, the Court of Appeals rendered an
Opinion Announcing Judgment of the Court. The appellate court affirmed-in-part
and reversed-in-part the District Court's earlier findings and remanded the case
to the District Court for a redetermination of the damage award. In its Opinion,
the appellate court reversed the District Court's opinion that certain WYKO
units infringed the Zygo patent on the basis of the doctrine of equivalents,
upheld the validity of Zygo's patent, and affirmed the District Court's opinion
that the original WYKO model 6000 infringed Zygo's patent. Zygo has not recorded
any gain from the District Court's earlier ruling and will not until a final
determination of the award is made.

$3,000,000.00                                           Date:  November 30, 1995

     FOR VALUE RECEIVED, the undersigned, Zygo Corporation (the "Borrower"),
hereby promises to pay to the order of SHAWMUT BANK CONNECTICUT, N.A.
(the "Bank") at the office of the Bank at 777 Main Street, Hartford, Connecticut
06115, or at such other address as the holder hereof may designate, the
principal sum of Three Million and 00/100 DOLLARS ($3,000,000.00), or the
aggregate unpaid principal amount of all advances made by the Bank to the
Borrower hereunder, which ever is less, in lawful money of the United States.
During the period from the date hereof until November 29, 1996 (as such date may
be extended, in writing from time to time, in the Bank's sole and absolute
discretion, the "Termination Date"), unless an Event of Default (as defined
below) occurs, the Borrower (SELECT ONE AND COMPLETE):

     |_|  may borrow, repay and reborrow.

     |X|  may borrow, repay and reborrow; provided, however, that for any period
          of twelve (12) consecutive months there shall be no borrowings or
          reborrowings and no outstanding principal under this Note for at least
          thirty (30) consecutive days.

     |_|  may borrow and repay; provided, however, that once any amount is
          repaid, such amount may NOT thereafter be reborrowed.

     The Borrower also promises to pay interest on each advance at the rate per
annum of zero (-0-) percentage points above the interest rate generally
announced by the Bank from time to time as its Base Rate (the "Base Rate"), and
to pay all taxes levied or assessed upon said advances against any holder of
this Note and to pay all costs, including attorneys' fees, costs relating to the
appraisal and/or valuation of assets and all costs incurred in the collection,
defense, preservation, administration, enforcement or protection of this Note or
in any guaranty or endorsement of this Note, or in any litigation arising out of
the transactions of which this Note or any guaranty or endorsement of this Note
is a part. All payments shall be applied first to the payment of interest on the
unpaid principal of all advances due under this Note and the balance on account
of the principal due under this Note.

     This Note has been executed and delivered subject to the following terms
and conditions:

     (1) Advances. All advances shall be due and payable on the Termination
Date. The Bank is authorized (but not required) to charge principal and interest
and all other amounts due under this Note to any account of the Borrower with
the Bank when and as it becomes due. If any advance is made, the Bank may, at
its option, record on the books and records of the Bank or endorse on Schedule 1
hereto, an appropriate notation evidencing any advance, each repayment on
account of the principal thereof, and the amount of interest paid; and the
Borrower authorizes the Bank to maintain such records or make such notations and
agrees that the amount shown on the books and records or on said Schedule 1, as
applicable, as outstanding from time to time shall constitute the amount owing
to the Bank pursuant to this Note, absent manifest error. In the event the
amount shown on Schedule conflicts with the amount noted as due pursuant to the
books and records of the Bank, the books and records of the Bank shall control
the disposition of the conflict.

     (2) Interest. Interest shall be payable monthly beginning January 1, 1996,
and continuing thereafter on the same day of each succeeding month and on the
Termination Date. Changes in the rate of interest resulting from changes in the
Base Rate shall take place immediately without notice or demand of any kind.
Interest on this Note shall be computed on the basis of a year of three hundred
sixty (360) days and actual days elapsed. Upon default or after maturity or
after judgment has been rendered on this Note, the unpaid principal balance of
all advances shall, at the option of the Bank, bear interest at a rate which is
four (4) percentage points per annum greater than that which would otherwise be
applicable. If, at any time, the rate of interest, together with all amounts
which constitute interest and which are reserved, charged or taken by Bank as
compensation for fees; services or expenses incidental to the making,
negotiating or collection of any advance evidenced hereby, shall be deemed by
any competent court of law, governmental agency or tribunal to exceed the
maximum rate of interest permitted to be charged by the Bank to the Borrower,
then, during such time as such rate of interest would be deemed excessive, that
portion of each sum paid attributable to that portion of such interest rate that
exceeds the maximum rate of interest so permitted shall be deemed a voluntary
prepayment of principal.

     (3) Additional Payments. If the Bank shall deem applicable of this Note
(including, in each case, any borrowed and any unused portion thereof, any
requirement of any law of the United States of America, any regulation, order,
interpretation, ruling, official directive or guideline (whether or not having
the force of law) of the Board of Governors of the Federal Reserve System, the
Comptroller of the currency, the Federal Deposit Insurance Corporation or any
other board or governmental or administrative agency of the United States of
America which shall impose, increase, modify or make applicable to this Note or
cause this Note to be included in any reserve, special deposit, calculation used
in the computation of regulatory capital standards, assessment or other
requirement which imposes on the Bank any cost that is attributable to the
maintenance thereof, then, and in each such event, the Borrower shall

<PAGE>

promptly pay the Bank, upon its demand, such amount as will compensate the Bank
for any such cost, which determination may be based upon the Bank's reasonable
allocation of the aggregate of such costs resulting from such events. In the
event any such cost is a continuing cost, a fee payable to the Bank may be
imposed upon the Borrower periodically for so long as any such cost is deemed
applicable by the Bank, in an amount determined by the Bank to be necessary to
compensate the Bank for any such cost, which determination may be based upon the
Bank's reasonable allocation of the aggregate of such costs resulting from such
events. The determination by the Bank of the existence and amount of any such
costs shall, in the absence of manifest error, be conclusive.

     (4) Late Charge. The Bank may collect a late charge not to exceed five (5)
percent of any installment of interest or principal, or of any other amount due
to the Bank which is not paid or reimbursed by the Borrower within fifteen (15)
days of the due date thereof to defray the extra cost and expense involved in
handling such delinquent payment and the increased risk of non-collection. The
minimum late charge shall be $15.00.

     (5) Review Fee. The Borrower agrees to pay to the Bank a review fee to
defray the Bank's expense involved in continuing to review the condition of the
Borrower and determining whether the Bank will make requested advances to the
Borrower. The review fee shall be payable on a quarterly basis, commencing on
January 1, 1996 and on the Termination Date and be in an amount equal to
$1,875.00.

     (6) Prepayment. The Borrower has the right to pay before due the unpaid
balance of this Note or any part thereof without penalty or premium. If, at any
time, the aggregate principal amount of all advances outstanding under this Note
shall exceed the maximum amount permitted by this Note, the Borrower shall
immediately prepay so much of the outstanding principal balance, together with
accrued interest on the portion of principal so prepaid, as shall be necessary
in order that the unpaid principal balance, after giving effect to such
prepayments, shall not be in excess of the maximum amount permitted by this
Note. All such prepayments will be applied first to the payment of accrued
interest to the date of the prepayment and the remainder to the principal
balances of this Note. 

     (7) Financial Statements; Notice or Default. The Borrower shall deliver to
the Bank (a) within forty-five (45) days after close of each of the first three
quarters of each fiscal year of the Borrower, if the Borrower is a corporation

                            Guaranty and Endorsement

     IN CONSIDERATION OF the advances or other extensions of credit or
accommodations evidenced by the within note, the undersigned (if more than one,
jointly and severally) hereby unconditionally guarantee(s) to SHAWMUT BANK
CONNECTICUT, N.A. and every subsequent holder of said note, irrespective of the
genuineness, validity, regularity or enforceability thereof or of any security
therefor or of the existence or extent of any such security, or of any other
circumstance, the prompt payment of said note and of all sums stated therein to
be payable, when due, at maturity, by acceleration or otherwise. Each signature
hereto is intended also as an endorsement of the within note, and the
undersigned hereby agree to be bound by all of the terms and conditions of said
note that pertain to guarantors and endorsers.

     The undersigned further agree to pay all costs and expenses, including
attorneys' fees, arising out of or with respect to the validity, enforceability,
defense or preservation of this Guaranty and Endorsement.

     The undersigned further guarantee that all payments made by the Borrower to
the Bank with respect to any liabilities hereby guarantied will, when made, be
final and agree that if any such payment is recovered from or repaid by the Bank
in whole or in part in any bankruptcy, insolvency or similar proceeding
instituted by or against the Borrower, this Guaranty and Endorsement shall
continue to be fully applicable to such liabilities to the same extent as though
the payment so recovered or repaid had never been originally made on such
liabilities. The undersigned hereby waive any claim, right or remedy which the
undersigned may now have or hereafter acquire against the Borrower or any of its
assets or property that arises hereunder or from the performance by the
undersigned hereunder, including without limitation, any claim, right or remedy
of subrogation, reimbursement, exoneration, contribution, indemnification or
participation in any claim, right or remedy that the Bank may have against the
Borrower or any collateral for the liabilities of the Borrower which the Bank
now has or hereafter acquires, whether or not such claim, right, or remedy
arises in equity, under contract, by statute, under common law or otherwise.

     Upon any default of the Borrower, the liability of the undersigned shall be
effective immediately and payable on demand without any suit or action against
the Borrower. No delay or omission on the part of Bank in exercising any right
hereunder shall operate as a waiver of such right or any other right; a waiver
on one occasion shall not be a bar to or waiver of any right on any other
occasion.

     The liability of the undersigned with respect to any liability shall not be
terminated by, and the undersigned assents to any extension or postponement of
the time of payment or any other indulgence, any modification, waiver or
amendment of the terms of any agreement relating to liabilities, any
substitution, exchange or release of collateral, the addition or release of any
party primarily or secondarily liable including any of the undersigned, whether
or not notice thereof is given to the undersigned. The Bank shall have no duty
to collect or protect any collateral or any income thereon, nor to preserve any
rights against other parties, and the Bank may proceed under this Guaranty and
Endorsement immediately upon Borrower's default without resorting to or regard
to any collateral or any other guaranty or source of payment.

                                     ALLONGE

     THIS ALLONGE, made this 30th day of November, 1995, amends and modifies
that certain Commercial Promissory Grid Note dated November 30, 1995 in the
original principal amount of Three Million and 00/100 ($3,000,000) Dollars (the
"Note") payable to the order of Shawmut Bank Connecticut, N.A. (the "Holder").

     Zygo Corporation (the "Maker") executed and delivered the Note in
connection with the extension of a revolving loan in said amount on such date
(the "Revolving Loan"). The Maker has requested Holder, and Holder has agreed,
to provide to Maker an alternative rate of interest for each Revolving Loan
advance effective from and after the date of Holder's acceptance of this
Allonge, subject to the terms and conditions set forth below. Maker therefore
wishes to amend the Note so as to set forth Maker's and Holder's agreement with
respect thereto.

     NOW, THEREFORE, in consideration of the foregoing premises and other good
and valuable consideration, the receipt and sufficiency of which being hereby
acknowledged and affirmed, Maker does hereby agree that the Note is hereby
amended as follows:

     1. By inserting after the word "advance" in the first line of the second
paragraph on page 1 which begins with the words "The Borrower" the phrase ", at
the election of the Borrower pursuant to the terms of this Note: (a)".

     2 By inserting after the phrase "(the "Base Rate")," in the second and
third lines of said second paragraph the phrase "or (b) at the rate per annum of
one hundred fifty (150) basis points (as determined for each Interest Period)
above IBOR for available Interest Periods of 30, 60 or 90 days,".

     3. By deleting Paragraph 1 in its entirety and substituting the following
in lieu thereof:

          "(1) Advances.

               (a) Definitions. As used above, in this Paragraph 1 and otherwise
     in this Note, the following terms shall have the following meanings:

                    (i) "Base Rate Loan" or "Base Rate Loans" means any advance
     or advances which bear interest determined with reference to the Base Rate.

                    (ii) "Business Day" means any day other than a day on which
     commercial banks in Hartford, Connecticut are required or permitted by law
     to close.

<PAGE>

                                       -2-


                    (iii) "Eurocurrency Liabilities" shall have the meaning
     assigned in Regulation D of the Board of Governors of the Federal Reserve
     System, as in effect from time to time.

                    (iv) "IBOR" means, for any LIBOR Rate Loan for the then
     current Interest Period relating thereto, the rate per annum determined
     pursuant to the following formula, as adjusted from time to time in
     accordance with subparagraph (a) (vii) of this Paragraph 1:

              IBOR = IBOR Base Rate
                     ----------------------
                     1 - Reserve Percentage

                    (iv) "IBOR Base Rate" means the rate quoted by the Bank to
     the Borrower two (2) Business Days prior to the first day of an available
     Interest Period for the offering to the Bank from prime commercial banks in
     the Interbank LIBOR market of dollar deposits in immediately available
     funds for a period equal to such Interest Period and in an amount equal to
     the amount of such LIBOR Rate Loan.

                    (v) "Interest Period" means with respect to each advance
     which the Borrower elects to be or continue to be a LIBOR Rate Loan, an
     available period of thirty (30), sixty (60) or ninety (90) days, as the
     Borrower may elect pursuant to subparagraphs (b), (c) and (d) of Paragraph
     1 of this Note, commencing on the date upon which such advance is made,
     continued as a LIBOR Rate Loan or converted from a Base Rate Loan to a
     LIBOR Rate Loan, as the case may be, and ending on the last day of such
     period provided, that:

                         (A) if any Interest Period would otherwise end on a day
     which is not a Business Day, such Interest Period shall end on the
     immediately preceding Business Day;

                         (B) any Interest Period that begins on the last
     Business Day of a calendar month (or on a day for which there is no
     numerically corresponding day in the calendar month at the end of such
     Interest Period) shall end on the last Business Day of a calendar month;
     and

                         (C) no Interest Period shall end after the Termination
     Date.

                    (vi) "LIBOR Rate Loan" or "LIBOR Rate Loans" means any
     advance or advances which bear interest at a rate determined with reference
     to IBOR.

<PAGE>

                                       -3-


                    (vii) "Reserve Percentage" means, for any Interest Period
     for each LIBOR Rate Loan, the reserve percentage applicable two (2)
     Business Days before the first day of such Interest Period under
     regulations issued from time to time by the Board of Governors of the
     Federal Reserve System (or any successor) for determining the maximum
     reserve requirement (including, without limitation, any emergency,
     supplemental or other marginal reserve requirement) for the Bank with
     respect to liabilities or assets consisting of or including Eurocurrency
     Liabilities (or with respect to any other category of liabilities that
     includes deposits by reference to which the interest rate on LIBOR Rate
     Loans is determined) having a term equal to such Interest Period.

               (b) Procedure for Advances, Payment. During the period from and
     including the date hereof to but excluding the Termination Date, so long as
     Borrower is in compliance with all of the terms and conditions of this Note
     and no Event of Default (as defined in Paragraph 10 of this Note) has
     occurred, and no condition exists which would constitute an Event of
     Default but for the giving of notice or passage of time, or both, Borrower
     may borrow, repay and reborrow advances hereunder; provided, however, that
     notwithstanding anything herein to the contrary, for each period of twelve
     (12) consecutive months there shall be no borrowings or reborrowings and no
     outstanding principal under this Note for at least thirty (30) consecutive
     days. Each advance shall be either a Base Rate Loan or a LIBOR Rate Loan as
     Borrower may elect subject to the provisions of this Note. Whenever
     Borrower desires an advance, Borrower shall notify the Bank (which notice
     shall be irrevocable) in writing or by telex, telecopy or telephone of the
     proposed borrowing. Such notice (each, an "Election Notice" and
     collectively, the "Election Notices") shall specify the date of the
     proposed borrowing (which shall be a Business Day), the type of borrowing
     (either a Base Rate Loan or a LIBOR Rate Loan), the amount to be borrowed
     (which amount for any LIBOR Rate Loan shall be not less than $100,000) and,
     if a LIBOR Rate Loan is requested, the duration of the initial available
     Interest Period. All Election Notices for advances which are Base Rate
     Loans must be received by Bank no later than 11:00 a.m., Hartford,
     Connecticut time on the day such borrowing is requested, and all Election
     Notices for advances which are LIBOR Rate Loans must be received by Bank no
     later than 10:00 a.m., Hartford, Connecticut time at least three (3)
     Business Days' prior to the day such borrowing is requested. If any advance
     is made, the Bank may, at its option, record on the books and records of
     the Bank or endorse on Schedule 1 hereto, an appropriate notation
     evidencing each advance hereunder, the interest rate applicable to each
     such advance, the due date for the


<PAGE>

                                       -4-


     repayment of each advance and repayments of all advances; and the Borrower
     authorizes the Bank to maintain such records or make such notations and
     agrees that the amount shown on the books and records or on said Schedule
     1, as applicable, as outstanding from time to time shall constitute the
     amount owing to the Bank pursuant to this Note, absent manifest error. In
     the event the amount shown on Schedule 1 conflicts with the amount noted as
     due pursuant to the books and records of the Bank, the books and records
     shall control the disposition of the conflict. UNLESS SOONER ACCELERATED AS
     A RESULT OF THE OCCURRENCE OF AN EVENT OF DEFAULT, ALL ADVANCES AND ANY
     OTHER SUMS DUE HEREUNDER SHALL BE DUE AND PAYABLE IN FULL ON THE
     TERMINATION DATE. The Bank is authorized (but not required) to charge
     principal and interest and all other amounts due under this Note to any
     account of the Borrower with the Bank when and as it becomes due.

               (c) Election and Continuation of Interest Periods for LIBOR Rate
     Loans. The Borrower shall elect the initial available Interest Period
     applicable to each advance hereunder which it elects to be a LIBOR Rate
     Loan by its applicable Election Notice given to the Bank pursuant to
     subparagraph (b) of Paragraph 1 of this Note or, in the case of each Base
     Rate Loan, by its notice of conversion given to the Bank pursuant to
     subparagraph (d) of Paragraph 1 of this Note, as the case may be. Any LIBOR
     Rate Loan may be continued as such upon the expiration of the then current
     Interest Period with respect thereto by the Borrower giving irrevocable
     written notice to the Bank of the duration of the next available Interest
     Period to be applicable to such LIBOR Rate Loan not less than three (3)
     Business Days prior to the last Business Day of the then current Interest
     Period with respect to such LIBOR Rate Loan provided that no LIBOR Rate
     Loan may be continued as such: (i) at a time when any Event of Default (or
     event or condition which would constitute an Event of Default but for the
     giving of notice or passage of time or both) has occurred and is
     continuing, (ii) in the event a LIBOR Rate Loan is unavailable pursuant to
     subparagraphs (e) and (f) of this Paragraph 1, and (iii) after the date
     that is thirty (30) days prior to the Termination Date. If the Bank does
     not receive timely notice of the next available Interest Period or if any
     LIBOR Rate Loan may no longer continue as such, such LIBOR Rate Loan shall
     be automatically converted, without notice, to a Base Rate Loan on the last
     day of the then expiring Interest Period.

               (d) Conversion of Base Rate Loans and LIBOR Rate Loans. The
     Borrower may elect from time to time to convert a LIBOR Rate Loan to a Base
     Rate Loan or a Base Rate Loan to a LIBOR Rate Loan by giving the Bank not
     less than three (3)

<PAGE>

                                       -5-


     Business Days' prior irrevocable written notice of such election provided
     that any such conversion of a LIBOR Rate Loan to a Base Rate Loan shall
     only be made on the last Business Day of an Interest Period with respect
     thereto. Any such notice of conversion to a LIBOR Rate Loan shall specify
     the amount of the Base Rate Loan being converted and the length of the
     initial available Interest Period. All or any part of outstanding advances
     hereunder which are Base Rate Loans may be converted as provided herein
     provided that no Base Rate Loan may be converted to a LIBOR Rate Loan: (i)
     at a time when any Event of Default (or event or condition which would
     constitute an Event of Default but for the giving of notice or passage of
     time or both) has occurred and is continuing, (ii) at a time when a LIBOR
     Rate Loan is unavailable pursuant to subparagraphs (e) and (f) of this
     Paragraph 1, and (ii) after the date that is thirty (30) days prior to the
     Termination Date.

               (e) Illegality. Notwithstanding any other provisions hereof, if
     any applicable law or governmental regulation, guideline, order or
     directive, or any change therein, or in the interpretation or application
     thereof by any governmental authority charged with the interpretation or
     the administration thereof (whether or not having the force of law) shall
     make it unlawful for the Bank to make or maintain LIBOR Rate Loans as
     contemplated by this Note: (i) the obligation of the Bank to make LIBOR
     Rate Loans, continue LIBOR Rate Loans as such and/or convert Base Rate
     Loans to LIBOR Rate Loans shall forthwith be cancelled, and (ii) such
     advances then outstanding as LIBOR Rate Loans, if any, shall be converted
     automatically, without notice, to Base Rate Loans on the respective last
     days of the then current Interest Periods with respect thereto or within
     such earlier time as required by law. If any such conversion of the LIBOR
     Rate Loans is made on a day that is not the last Business Day of the then
     current Interest Period applicable thereto, Borrower shall pay the Bank
     such amount or amounts required pursuant to subparagraph (g) of Paragraph 1
     of this Note.

               (f) Basis for Determining IBOR Inadequate or Unfair. In the event
     that the Bank shall have determined (which determination shall be
     conclusive and binding upon Borrower) that (i) by reason of circumstances
     affecting the Interbank LIBOR market, adequate and reasonable means do not
     exist for determining IBOR, or (ii) Dollar deposits in the relevant amount
     and for the relevant maturity are no longer available to the Bank in the
     Interbank LIBOR market, or (iii) the making or continuation of LIBOR Rate
     Loans has been made impractical or unlawful by the occurrence of a
     contingency that materially and adversely affects the

<PAGE>

                                       -6-


     Interbank LIBOR market, or (iv) the IBOR Base Rate will not adequately and
     fairly reflect the cost to the Bank of making or maintaining LIBOR Rate
     Loans, or (v) the IBOR Base Rate shall no longer represent the effective
     cost to the Bank of U.S. Dollar deposits in the relevant market for
     deposits in which it regularly participates, the Bank shall give the
     Borrower notice of such determination as soon as practicable. If such
     notice is given (A) any requested LIBOR Rate Loan shall be made as a Base
     Rate Loan, unless the Borrower gives the Bank three (3) Business Days'
     prior written notice that its request for such borrowing is cancelled, (B)
     any Base Rate Loan that was to have been converted to a LIBOR Rate Loan
     shall be continued as a Base Rate Loan, and (C) any outstanding LIBOR Rate
     Loan shall be automatically converted, without notice, to a Base Rate Loan
     effective on the last Business Day of the then current Interest Period
     applicable thereto. Until such notice has been withdrawn, no further LIBOR
     Rate Loans shall be made or continued as such, nor shall the Borrower have
     the right to convert Base Rate Loans to LIBOR Rate Loans.

               (g) Indemnity. The Borrower agrees to indemnify the Bank and to
     hold the Bank harmless from any loss (including any of the additional
     payments referred to in Paragraph 3 of this Note and any lost profits) or
     expense that it may sustain or incur as a consequence of (i) a default by
     the Borrower in the payment of the principal of or interest on any LIBOR
     Rate Loan, (ii) the failure by the Borrower to complete a borrowing of,
     conversion into or continuation of a LIBOR Rate Loan after notice thereof
     has been given, or (iii) the making of a prepayment of a LIBOR Rate Loan on
     a day which is not the last day of the then current Interest Period
     applicable thereto, including, but not limited to, in each case, any such
     loss or expense arising from the reemployment of funds obtained by it or
     from fees, interest or other amounts payable to terminate the deposits from
     which such funds were obtained. The Bank shall prepare a certificate as to
     any additional amounts payable to it pursuant to this subparagraph (g),
     which certificate shall be submitted by the Bank to the Borrower and shall,
     absent manifest error, be deemed conclusive.

               (h) Survival. The obligations of Borrower under this Paragraph 1
     shall survive the payment of all advances made hereunder."

     4. By adding to the end of the first sentence of Paragraph 2 the following:

<PAGE>

                                       -7-


     "; provided, however, that interest on each LIBOR Rate Loan shall be
     charged and payable for each such Interest Period on the last Business Day
     of each such Interest Period."

     5. By adding to the end of the second sentence of Paragraph 2 the
following:

     ", and changes in the rate of interest resulting from changes in the
     Reserve Percentage shall become effective, without notice or demand of any
     kind, on the date on which such change in the Reserve Percentage becomes
     effective."

                              EMPLOYMENT AGREEMENT

     AGREEMENT, made as of August 7, 1996, between TECHNICAL INSTRUMENT COMPANY,
a California corporation with an office at 650 North Mary Avenue, Sunnyvale,
California 94086 (the "Company"), and Francis E. Lundy, residing at Six-Friars
Lane, Mill Valley, California 94941 ("Employee").

                              W I T N E S S E T H:

     WHEREAS, the Company desires that Employee be employed by the Company, and
Employee desires to be so employed by the Company upon the terms and conditions
herein set forth.

     NOW, THEREFORE, in consideration of the premises and of the mutual
promises, representations and covenants herein contained, the parties hereto
agree as follows:

     1.  EMPLOYMENT.

     The Company hereby employs Employee and Employee hereby accepts such
employment, subject to the terms and conditions herein set forth. Employee shall
hold the position of President of Technical Instrument Company, a business unit
initially being operated in the form of a subsidiary of Zygo Corporation
("Zygo").

     2.  TERM.

     The initial term of employment under this Agreement shall begin on August
7, 1996 (the "Employment Date") and shall continue for a period of three (3)
years from that date, subject to prior termination in accordance with the terms
hereof. Thereafter, this Agreement shall automatically be renewed for successive
one year terms unless either party shall give the other sixty (60) days' prior
written notice of its or his intent not to renew this Agreement. The initial
term together with all such additional one-year period(s) of employment, if any,
are collectively referred to herein as the "term" of this Agreement.

     3.  COMPENSATION.

     As compensation for the employment services to be rendered by Employee
hereunder, the Company agrees to pay, or cause to be paid, to Employee, and
Employee agrees to accept, an annual salary of $150,000 or such higher amount as
the President of Zygo may determine from time to time, subject to such payroll
deductions as are

<PAGE>

required by law and deductions for applicable employee contributions to the
normal benefit programs of the Company. The annual salary provided for hereunder
shall be payable in equal installments commencing at the Employment Date, in
accordance with the Company's practice. In addition, Employee shall be entitled
to additional incentive compensation from time to time. Such compensation will
be based on the Company's overall performance and will be awarded at the
discretion of the President of Zygo with the approval of the Board of Directors
of the Company or Zygo.

     On or before August 14, 1996, Employee shall receive a grant of options to
purchase 20,000 shares of Common Stock of Zygo with an exercise price equal to
the fair market value on the date of grant, vesting in four equal installments
and otherwise in accordance with the terms of Zygo's Amended and Restated
Non-Qualified Stock Option Plan.

     4.  EXPENSES.

     The Company shall pay or reimburse Employee, upon presentment of suitable
vouchers, for all reasonable business and travel expenses which may be incurred
or paid by Employee in connection with his employment hereunder. Employee shall
comply with restrictions and shall keep records in compliance with the Company's
policy and procedure related to travel and entertainment expenses.

     5.  INSURANCE AND OTHER BENEFITS.

         (a) Employee shall be entitled to such vacations and to participate in
and receive any other health and welfare (including insurance) benefits
customarily provided by the Company for its employees generally, all as
determined from time to time by the Board of Directors of the Company or Zygo or
appropriate committee thereof; provided that the health and welfare benefits in
the aggregate provided to Employee are at least substantially comparable to the
benefits provided by the Company to Employee set forth on Schedule 5(a) attached
hereto, all of which benefits Employee represents are benefits provided by the
Company to Employee prior to the date hereof. The Company currently intends to
initially afford Employee the same health and welfare benefits as are set forth
in Schedule 5(a). Unused annual vacations may be carried over to the extent
permitted by Company policy.

         (b) Employee acknowledges and agrees that notwithstanding anything to
the contrary contained in any health or welfare benefit plan maintained by Zygo,
except as may be otherwise agreed to by Employee and Zygo, Employee shall not be
entitled to participate in any of Zygo's employee benefit plans by virtue of his
being employed by the Company or Zygo (if and when applicable).

     6.  DUTIES.

         (a) Employee shall perform such duties and functions as the President,
Chief Executive Officer or Chief Operating Officer of Zygo and the Board of
Directors

                                       -2-

<PAGE>

of the Company or Zygo shall from time to time determine and Employee shall
comply in the performance of his duties with the policies of, and be subject to,
the direction of such officers and such Boards of Directors. Neither the Company
nor Zygo shall relocate Employee's office outside of the San Francisco Bay Area
without Employee's consent and any such relocation not consented to by Employee
shall be deemed a termination of Employee's employment by the Company for
purposes of Section 7(h) hereof.

         (b) Employee agrees to devote his entire working time, attention and
energies to the performance of the business of the Company and of any of its
subsidiaries or affiliates by which he may be employed; and Employee shall not,
directly or indirectly, alone or as a member of any partnership or other
organization, or as an officer, director or employee of any other corporation,
partnership or other organization, be actively engaged in or concerned with any
other duties or pursuits which interfere with the performance of his duties
hereunder, or which, even if non-interfering, may be inimical, or contrary, to
the best interests of the Company, except those duties or pursuits specifically
authorized by the Board of Directors of the Company or Zygo.

     7.  TERMINATION OF EMPLOYMENT; EFFECT OF TERMINATION.

         (a)  Employee's employment hereunder may be terminated at any time
upon written notice from the Company to Employee,

              (i) upon the determination by the President, Chief Executive
         Officer or Chief Operating Officer of Zygo or the Board of Directors of
         the Company or Zygo that Employee's performance of his duties has not
         been fully satisfactory for any reason which would not constitute
         justifiable cause (as hereinafter defined) upon five (5) days' prior
         written notice to Employee; or

              (ii) immediately upon determination by the Board of Directors of
         the Company or Zygo that justifiable cause exists for such termination.

         (b)  Employee's employment shall terminate upon:

              (i) the death of the Employee; or

              (ii) the "disability" of Employee (as hereinafter defined pursuant
         to subsection (d) herein).

         (c) Employee's employment hereunder may be terminated at any time upon
thirty (30) days' prior written notice from the Employee to the Company.

         (d) For the purposes of this Agreement, the term "disability" shall
mean the inability of Employee, due to illness, accident or any other physical
or mental

                                       -3-

<PAGE>

incapacity, to perform his duties in a normal manner for a period of three (3)
consecutive months or for a total of four (4) months (whether or not
consecutive) in any twelve (12) month period during the term of this Agreement.

         (e) For the purposes hereof, the term "justifiable cause" shall mean
and be limited to: any repeated failure or refusal by Employee to perform or
willful neglect by Employee of, any of his duties pursuant to this Agreement;
Employee's conviction (which, through lapse of time or otherwise, is not subject
to appeal) of any crime or offense involving money or other property of the
Company, Zygo or any of their respective subsidiaries or affiliates or which
constitutes a felony in the jurisdiction involved; Employee's performance of any
act or his failure to act, for which if he were prosecuted and convicted, a
crime or offense involving money or property of the Company, Zygo or any of
their respective subsidiaries or affiliates, or which constitutes a felony in
the jurisdiction involved, would have occurred; any disclosure by Employee to
any person, firm or corporation other than the Company, Zygo or any of their
respective subsidiaries or affiliates and its and their directors, officers and
employees, of any confidential information or trade secret of the Company, Zygo
or any of their respective subsidiaries or affiliates or any other breach by
Employee of any of the provisions of Section 10 hereof; any attempt by Employee
to secure any personal profit in connection with the business of the Company,
Zygo or any of their respective subsidiaries or affiliates; or the engaging by
Employee in any business or activities other than the business of the Company,
Zygo and their respective subsidiaries or affiliates which interferes with the
performance of his duties. Upon termination of Employee's employment by the
Company for justifiable cause or upon termination of Employee's employment by
Employee pursuant to Section 7(c) hereof, this Agreement shall terminate
immediately and Employee shall not be entitled to any amounts or benefits
hereunder other than such portion of Employee's annual salary and reimbursement
of expenses pursuant to Section 4 hereof as has been accrued through the date of
his termination of employment.

         (f) If Employee shall die during the term of his employment hereunder,
this Agreement shall terminate immediately. In such event, the estate of
Employee shall thereupon be entitled to receive such portion of Employee's
annual salary and reimbursement of expenses pursuant to Section 4 hereof as has
been accrued through the date of his death.

         (g) Upon Employee's "disability," the Company shall have the right to
terminate Employee's employment. Notwithstanding any inability to perform his
duties, Employee shall be entitled to receive his compensation as provided
herein until the termination of his employment for disability. Any termination
pursuant to this subsection (g) shall be effective on the date thirty (30) days
after which Employee shall have received written notice of the Company's
election to terminate. Notwithstanding anything to the contrary contained
herein, during any period that Employee fails to perform his duties hereunder as
a result of his disability (but prior to receiving the notice of termination
specified in this Section 7(g), (i) Employee shall continue to receive his full
salary at the rate then in effect and all benefits provided in Section 5

                                       -4-

<PAGE>

hereof, provided that payments made to Employee pursuant to this Section 7(g)
shall be reduced by the sum of the amounts, if any, payable to Employee at or
prior to the time of any such payment under any disability benefit plan or
program of, or provided by, the Company or Zygo, and (ii) the Company shall have
the right to hire any other individual or individuals to perform such duties and
functions as the Company shall desire, including those duties heretofore
performed by Employee.

         (h) Notwithstanding any provision to the contrary contained herein, in
the event that Employee's employment is terminated by the Company at any time
for any reason other than justifiable cause, disability or death, the parties
hereto agree that damages to Employee shall be difficult to ascertain in any
such event, but in order to limit the liability of the Company and Zygo in any
such event, Employee shall be entitled to receive as liquidated damages and not
as a penalty, and the Company shall pay to Employee, Employee's salary (payable
in such amount and in such manner as set forth in Section 3 herein) from and
after the date of such termination for a period ending (i) at the end of the
three year initial term of this Agreement if such termination occurs during such
initial three year term, provided, however, that in the event termination occurs
within the last six (6) months of the initial three year term, Employee would be
entitled to his salary for a period ending six (6) months from the date of such
termination, or (ii) six (6) months from the date of termination if such
termination occurs during any renewal term subsequent to such initial three year
term, which amount shall be in lieu of any and all other payments due and owing
to Employee under the terms of this Agreement or otherwise.

     as indicated on Exhibit 1 hereto, there are no employment agreements,
     confidentiality agreements, restrictive covenants or other agreements or
     restrictions binding on the Employee or to which the Employee is a party

Company practice. In addition, Employee shall be entitled to additional
contingent compensation from time to time. Such compensation will be based on
the Company's overall performance and will be awarded at the discretion of the

Chief Executive Officer or Chief Operating Officer of Zygo and the Board of

         (b) Employee agrees to devote his entire working time, attention and
energies to the performance of the business of the Company and of any of its
subsidiaries or affiliates by which he may be employed; and Employee shall not,
directly or indirectly, alone or as a member of any partnership or other
organization, or as an officer, director or employee of any other corporation,
partnership or other organization, be actively engaged in or concerned with any
other duties or pursuits which interfere with the performance of his duties
hereunder, or which, even if non-interfering, may be inimical, or contrary, to
the best interests of the Company, except those duties or pursuits specifically
authorized by the Board of Directors of the Company or Zygo.

     7.  TERMINATION OF EMPLOYMENT; EFFECT OF TERMINATION.

         (a)  Employee's employment hereunder may be terminated at any time
upon written notice from the Company to Employee,

              (i) upon the determination by the President, Chief Executive
         Officer or Chief Operating Officer of Zygo or the Board of Directors of
         the Company or Zygo that Employee's performance of his duties has not
         been fully satisfactory for any reason which would not constitute
         justifiable cause (as hereinafter defined) upon five (5) days' prior
         written notice to Employee; or

              (ii) immediately upon determination by the Board of Directors of
         the Company or Zygo that justifiable cause exists for such termination.

         (b)  Employee's employment shall terminate upon:

              (i) the death of the Employee; or

              (ii) the "disability" of Employee (as hereinafter defined pursuant
         to subsection (c) herein).

         (c) For the purposes of this Agreement, the term "disability" shall
mean the inability of Employee, due to illness, accident or any other physical
or mental incapacity, to perform his duties in a normal manner for a period of
three (3) consecutive months or for a total of four (4) months (whether or not
consecutive) in any twelve (12) month period during the term of this Agreement.

         (d) For the purposes hereof, the term "justifiable cause" shall mean
and be limited to: any repeated failure or refusal by Employee to perform, or
willful neglect by Employee of, any of his duties pursuant to this Agreement;
Employee's conviction (which, through lapse of time or otherwise, is not subject
to appeal) of any crime or offense involving money or other property of the
Company, Zygo or any of their respective subsidiaries or affiliates or which
constitutes a felony in the jurisdiction

                                       -3-

<PAGE>

involved; Employee's performance of any act or his failure to act, for which if
he were prosecuted and convicted, a crime or offense involving money or property
of the Company, Zygo or any of their respective subsidiaries or affiliates, or
which constitutes a felony in the jurisdiction involved, would have occurred;
any disclosure by Employee to any person, firm or corporation other than the
Company, Zygo or any of their respective subsidiaries or affiliates and its and
their directors, officers and employees, of any confidential information or
trade secret of the Company, Zygo or any of their respective subsidiaries or
affiliates or any other breach by Employee of any of the provisions of Section
10, 11 or 12 hereof; any attempt by Employee to secure any personal profit in
connection with the business of the Company, Zygo or any of their respective
subsidiaries or affiliates; or the engaging by Employee in any business or
activities other than the business of the Company, Zygo and any of their
respective subsidiaries or affiliates which interferes with the performance of
his duties hereunder. Upon termination of Employee's employment for justifiable
cause, this Agreement shall terminate immediately and Employee shall not be
entitled to any amounts or benefits hereunder other than such portion of
Employee's annual salary and reimbursement of expenses pursuant to Section 4
hereof as has been accrued through the date of his termination of employment.

         (e) If Employee shall die during the term of his employment hereunder,
this Agreement shall terminate immediately. In such event, the estate of
Employee shall thereupon be entitled to receive such portion of Employee's
annual salary and reimbursement of expenses pursuant to Section 4 hereof as has
been accrued through the date of his death.

         (f) Upon Employee's "disability," the Company shall have the right to
terminate Employee's employment. Notwithstanding any inability to perform his
duties, Employee shall be entitled to receive his compensation as provided
herein until the termination of his employment for disability. Any termination
pursuant to this subsection (f) shall be effective on the date thirty (30) days
after which Employee shall have received written notice of the Company's
election to terminate. Notwithstanding anything to the contrary contained
herein, during any period that Employee fails to perform his duties hereunder as
a result of his disability (but prior to receiving the notice of termination
specified in this Section 7(f), (i) Employee shall continue to receive his full
salary at the rate then in effect and all benefits provided in Section 5 hereof,
provided that payments made to Employee pursuant to this Section 7(f) shall be
reduced by the sum of the amounts, if any, payable to Employee at or prior to
the time of any such payment under any disability benefit plan or program of, or
provided by, the Company or Zygo, and (ii) the Company shall have the right to
hire any other individual or individuals to perform such duties and functions as
the Company shall desire, including those duties heretofore performed by
Employee.

         (g) Notwithstanding any provision to the contrary contained herein, in
the event that Employee's employment is terminated by the Company at any time
for any reason other than justifiable cause, disability or death, the parties
hereto agree that

                                       -4-

<PAGE>

damages to Employee shall be difficult to ascertain in any such event, but in
order to limit the liability of the Company and Zygo in any such event, Employee
shall be entitled to receive as liquidated damages and not as a penalty, and the
Company shall pay to Employee, Employee's salary (payable in such amount and in
such manner as set forth in Section 3 herein) from and after the date of such
termination for a period ending (i) at the end of the three year initial term of
this Agreement if such termination occurs during such initial three year term,
provided, however, that in the event termination occurs within the last six (6)
months of the initial three year term, Employee would be entitled to his salary
for a period ending six (6) months from the date of such termination, or (ii)
six (6) months from the date of termination if such termination occurs during
any renewal term subsequent to such initial three year term, which amount shall
be in lieu of any and all other payments due and owing to Employee under the
terms of this Agreement or otherwise.

     8.  REPRESENTATIONS AND AGREEMENTS OF EMPLOYEE.

         (a) Employee represents and warrants that he is free to enter into this
Agreement and to perform the duties required hereunder, and that there are no
employment contracts or understandings, restrictive covenants or other
restrictions, whether written or oral, preventing the performance of his duties
hereunder. Employee further represents and warrants that he is in full
compliance with all existing agreements between himself and the Company or Zygo.

         (b) Employee agrees to submit to a medical examination and to cooperate
and supply such other information and documents as may be required by any
insurance company in connection with the Employees' inclusion in any insurance
or fringe benefit plan or program as the Company shall determine from time to
time to obtain, or in connection with, in the Company's or Zygo's sole
discretion, the Company's obtaining life insurance for its benefit on the life
of Employee.

     9.  NON-COMPETITION.

         (a) Employee agrees that during his employment by the Company (which
shall be deemed to include the period in which Employee is receiving any
severance payments set forth in Section 7(g) hereto), and for a period of three
(3) years after the later to occur of the termination or expiration of
Employee's employment hereunder (the "Non-Competitive Period"), Employee shall
not, directly or indirectly, as owner, partner, joint venturer, stockholder,
employee, broker, agent, principal, trustee, corporate officer, director,
licensor, or in any capacity whatsoever engage in, become financially interested
in, be employed by, render any consultation or business advice with respect to,
or have any connection with, any business engaged in the research, development,
testing, design, manufacture, sale, lease, marketing, utilization or
exploitation of any products or services which are designed for the same purpose
as, are similar to, or are otherwise competitive with, products or services of
the Company, Zygo or any of their respective subsidiaries or affiliates which
are being sold or

                                       -5-

<PAGE>

provided or proposed to be provided at the time of termination of Employee's
employment, in any geographic area where, at the time of the termination or
expiration of his employment hereunder, the business of the Company, Zygo or any
of their respective subsidiaries or affiliates was being conducted or was
proposed to be conducted in any manner whatsoever; provided, however, that
Employee may own any securities of any corporation which is engaged in such
business and is publicly owned and traded but in an amount not to exceed at any
one time one percent (1%) of any class of stock or securities of such
corporation. In addition, Employee shall not, directly or indirectly, during the
Non-Competitive Period, request or cause contracting parties, suppliers or
customers with whom the Company, Zygo or any of their respective subsidiaries or
affiliates has a business relationship to cancel or terminate any such business
relationship with the Company, Zygo or any of their respective subsidiaries or
affiliates or solicit, interfere with or entice from the Company, Zygo or any of
their respective subsidiaries or affiliates any employee (or former employee) of
the Company, Zygo or any of their respective subsidiaries or affiliates.
Notwithstanding the foregoing, in the event Employee's employment hereunder is
terminated by the Company for justifiable cause pursuant to Section 7(a) hereof,
the Non-Competitive Period shall continue through the expiration of the
scheduled term of this Agreement as provided in Section 2 hereof.

         (b) If any portion of the restrictions set forth in this Section 9
should, for any reason whatsoever, be declared invalid by a court of competent
jurisdiction, the validity or enforceability of the remainder of such
restrictions shall not thereby be adversely affected.

         (c) Employee acknowledges that the Company and/or Zygo conducts
business on a world-wide basis, that its sales and marketing prospects are for
continued expansion into world markets and that, therefore, the territorial and
time limitations set forth in this Section 9 are reasonable and properly
required for the adequate protection of the business of the Company, Zygo and
their respective subsidiaries. In the event any such territorial or time
limitation is deemed to be unreasonable by a court of competent jurisdiction,
Employee agrees to the reduction of the territorial or time limitation to the
area or period which such court deems reasonable.

         (d) The existence of any claim or cause of action by Employee against
the Company, Zygo or any of their respective subsidiaries or affiliates shall
not constitute a defense to the enforcement by the Company, Zygo or any such
subsidiary or affiliate of the foregoing restrictive covenants, but such claim
or cause of action shall be litigated separately.

     10. INVENTIONS AND DISCOVERIES.

         (a) Employee shall promptly and fully disclose to Zygo, and with all
necessary detail for a complete understanding of the same, all developments,
know-how, discoveries, inventions, improvements, concepts, ideas, writings,
formulae, processes and

                                       -6-

of his employment with the Company, Zygo or any of their respective subsidiaries
or affiliates, solely or jointly with others, in all instances in or relating to
any activities of the Company, Zygo or any of their respective subsidiaries or
affiliates known to him as a consequence of his employment hereunder
(collectively the "Subject Matter").

         (b) Employee hereby assigns and transfers, and agrees to assign and
transfer, to Zygo, all his rights, title and interest in and to the Subject
Matter, and Employee further agrees to deliver to Zygo any and all drawings,
notes, specifications and data relating to the Subject Matter, and to execute,
acknowledge and deliver all such further papers, including applications for
copyrights or patents, as may be necessary to obtain copyrights and patents for
any thereof in any and all countries and to vest title thereto to Zygo. Employee
shall assist Zygo in obtaining such copyrights or patents during the term of
this Agreement, and any time thereafter on reasonable notice, and Employee
agrees to testify in any prosecution or litigation involving any of the Subject
Matter.

     11. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.

         (a) Employee shall not, during the term of this Agreement or at any
time following termination or expiration of this Agreement, directly or
indirectly, disclose or permit to be known (other than as is required in the
regular course of his duties or required by law (in which case Employee shall
give Zygo prior written notice of such required disclosure) or with the prior
written consent of the President of Zygo), to any person, firm or corporation,
any confidential information acquired by Employee during the course of, or as an
incident to, his employment hereunder, relating to the Company, Zygo or any of
their respective subsidiaries or affiliates, the directors of the Company, Zygo
or any of their respective subsidiaries or affiliates, any client of the
Company, Zygo or any of their respective subsidiaries or affiliates, or any
corporation, partnership or other entity owned or controlled, directly or
indirectly, by any of the foregoing, or in which any of the foregoing has a
beneficial interest, including, but not limited to, the business affairs of each
of the foregoing. Such confidential information shall include, but shall not be
limited to, proprietary technology, trade secrets, patented processes, research
and development data, know-how, market studies and forecasts, competitive
analyses, pricing policies, employee lists, personnel policies, the substance of
agreements with customers, suppliers and others, marketing or dealership
arrangements, servicing and training programs and arrangements, customer lists
and any other documents embodying such confidential information. This
confidentiality obligation shall not apply to any confidential information which
thereafter becomes publicly available other than pursuant to a breach of this
Section 11(a), directly or indirectly, by Employee.

their respective subsidiaries or affiliates as hereinabove described (or other

case may be, and Employee shall use commercially reasonable best efforts to
prevent any publication or disclosure thereof. Upon termination of Employee's
employment with the Company, all documents, records, reports, writings and other
similar documents containing confidential information, including copies thereof,
then in Employee's possession or control shall be returned and left with the
Company.

         (c) Employee will execute the form of "NexStar Corporation

all the terms and provisions of which are incorporated herein as if fully set

of this Agreement by Employee, the Company shall be entitled to injunctive
relief or any other legal or equitable remedies. Employee agrees that the
Company may recover by appropriate action the amount of the actual damage caused
the Company by any failure, refusal or neglect of Employee to perform his

same event or any other event.

valid unless made in writing and signed by both of the parties hereto.

jurisdiction of the courts of the State of Connecticut, including the
jurisdiction of the United States District Courts therein, and agrees not to
assert by way of motion, as a defense or otherwise, in any such suit, action or
proceeding, any claim that he or it is not subject to the jurisdiction of the
above-named courts, that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is

                                       -8-

                  NON-DISCLOSURE AND NON-SOLICITATION AGREEMENT

     AGREEMENT, dated as of ___________ __, 1996, by and between NEXSTAR
CORPORATION, a Delaware corporation (the "Company"), and Ahmad Akrami (the
"Employee")

                              W I T N E S S E T H:

     In consideration of the Company's employment of the Employee and in
consideration of the covenants contained herein, the parties hereby agree as
follows:

1.   The Employee agrees that he will not directly or indirectly disclose or use
     at any time any knowledge, information or material relating to any
     business, customer, machine, design, apparatus or systems of the Company,
     Zygo Corporation, a Delaware corporation and the owner of all the
     outstanding capital stock of the Company ("Zygo"), or any of their
     respective subsidiaries or affiliates or any of the methods of conducting
     any part of their respective businesses or the like which may become known
     to the Employee by reason of his employment or otherwise except as may be
     reasonably necessary to the performance of his assigned duties as an
     employee of the Company.

2.   The Employee agrees to promptly and completely disclose in writing to such
     person as the Company may designate all ideas, developments, inventions and
     improvements heretofore or hereafter made, developed, perfected, devised,
     conceived or acquired by the Employee either solely or jointly with others
     during the Employee's employment by the Company and within ninety (90) days
     after any termination thereof, whether or not during regular working hours,
     relating in any way to the actual or anticipated business, research,
     developments or products of the Company; and if so requested by the
     Company, to assign, transfer and convey to the Company all right, title and
     interest in and to all such ideas, developments, inventions and
     improvements.

3.   The Employee agrees, at the request and expense of the Company, to make,
     execute and deliver any and all papers, documents and instruments,
     including applications for patents in any and all countries and reissues
     and extensions thereof, and to assist and cooperate (without expense to the
     Employee) with the Company or its representative in any controversy or
     legal proceedings relating to said ideas, developments, inventions and
     improvements, and the patents which may be procured thereon.

                                       -1-

4.   The Company does not assume any responsibility for the prosecution or
     defense of any application for patents in any countries arising from ideas,
     developments, inventions and improvements disclosed to the Company pursuant
     to this Agreement.

5.   The Employee represents and warrants that he/she is free to enter into the
     employment arrangements and, if applicable, the employment agreement, to be
     entered into with the Company and to perform the duties required of the
     Employee in connection with his/her employment by the Company; and that,
     except as indicated on Exhibit 1 hereto, there are no employment
     agreements, confidentiality agreements, restrictive covenants or other
     agreements or restrictions binding on the Employee or to which the Employee
     is a party which limit, prohibit or prevent the full performance by the
     Employee of his/her employment duties and arrangements with the Company or
     which would preclude the Employee from disclosing or otherwise limit the
     Employee's right to disclose to the Company any ideas, inventions,
     discoveries or other information.

6.   The Employee represents and warrants that he/she has not brought and agrees
     that he/she will not bring to the Company or use in the performance of
     his/her employment responsibilities at the Company any materials,
     documents, trade secrets or confidential information of a former employer
     or any other person which are of a confidential nature or which are not
     generally available to the public. The Employee agrees that he/she has not
     and will not disclose to the Company or seek to induce the Company to use
     any such confidential information, materials, documents or trade secrets.

7.   The Employee agrees that during his/her employment by the Company and
     following the termination of such employment, the Employee will not,
     directly or indirectly, request or cause any suppliers or customers with
     whom the Company, Zygo or any of its subsidiaries or affiliates has a
     business relationship to cancel or terminate any such business relationship
     with the Company, Zygo or any of their respective subsidiaries or
     affiliates or solicit, interfere with or entice from the Company any
     employee or former employee of the Company or Zygo.

8.   Neither this Agreement nor any benefits hereunder are assignable by the
     Employee, but the terms and provisions hereof shall inure to the benefit of
     the Company's successors and assigns.

9.   This Agreement is not a contract of employment; it does not give the
     Employee any rights to any employment with the Company, and it in no way
     abridges, alters, amends or modifies any rights the Company may otherwise
     have to terminate its employment of the Employee.

10.  This Agreement, together with the Employment Agreement, dated September
     ___, 1996, by and between the Employee and the Company and the Acquisition
     Agreement, dated as of August 12, 1996, by and among Zygo, NX Acquisition

TO OUR SHAREOWNERS

[Photograph of Gary K. Willis]

Your company completed fiscal 1996, the first year of its second quarter
century, by once again posting record performance. Net sales of $53.5 million
for 1996 were up 66% as compared to 1995 net sales of $32.2 million. Again, as
was the case in fiscal 1995, operating profits, pretax profits, and net earnings
per share not only increased significantly over the previous year levels but
attained historical highs for your company. Net earnings of $1.53 per share
increased 135% from net earnings of $.65 per share in fiscal 1995. These
earnings performance records were once again achieved as a result of
significantly increased revenues in all sectors of our business: instruments
and systems, precision optical components, and customer services, combined with
record high productivity within our operations. Our quantitative productivity
measure, sales per employee, reached an historic high for the Company at
$240,000 per employee, topping last year's previous record of $173,000 of sales
per employee -- a gain of greater than 38%. The strong demand across our product
and service lines not only fueled the significant sales increases we enjoyed,
but also resulted in establishing a year end record backlog of slightly over
$19 million compared to the previous year end record of nearly $13 million for
1995, an increase of almost 46%.

In addition to this outstanding operations performance for fiscal 1996, your
company also reached a number of significant milestones that strengthen our
ability to serve our emerging customer needs and provide opportunities to
increase value for our loyal shareowners. These included a 3-for-2 stock split
in the first quarter of our fiscal year, the consummation of a secondary
offering of 1.3 million shares of your company's stock in the second quarter of
our fiscal year, the addition to our cadre of corporate officers and to our
Board of Directors in the third and fourth quarters of our fiscal year, and the
announcement of two synergistic acquisitions in the fourth quarter as we closed
our fiscal year.  Let us address each of these individually.

STOCK SPLIT:  In order to respond to an increasing demand for your company's
securities generated by our growth and improving financial performance, your
Board of Directors authorized a 3-for-2 stock split effected in the form of a
50% stock dividend which was paid on August 21, 1995 to shareowners of record
on August 1, 1995. This action increased the practical float, those shares which
are not closely held, from 1.4 million shares to 2.1 million shares and assisted
in placing the Company's securities in a position where the float could now
attract a number of valueoriented institutional investors, an important
shareowner constituency to your company as we move ahead.

SECONDARY OFFERING:  During December 1995, your company consummated a secondary
offering of 1.3 million shares of your company's stock for $29.00 per share.
This secondary offering, in which the Company sold 845,000 shares of stock,
provided your company with approximately $22.7 million in new capital, helping
to ensure that the necessary capital to fund our future growth is available to
the Company. The secondary offering also benefited your company by reducing the
amount of closely held shares from approximately 47% to approximately 30%,
further increasing our public float, and by providing the opportunity to
reintroduce a restructured Zygo with its new strategy to the investment
community. Your company's management had the pleasure of reporting on our recent
performance and describing our ongoing strategic plans to over 50 major
institutional investors and brokerage firms, focusing on our transition from a
provider of quality control laboratory instruments to a production yield
improvement system supplier to high technology industries. These discussions
allowed us the opportunity to describe the key elements of our company's ongoing
strategy, our efforts to enhance our market leadership through innovative
technical solutions, and the creation of the strongest possible relationships
with the industry leaders in our

Page 1

<PAGE>

major served markets. A number of these solutions and the measurement and
sensor technologies they are based on are described on pages 3 through 7 of this
annual report.

STRATEGIC ACQUISITIONS:  During April and at the close of our fiscal year, we
had the pleasure of announcing the signing of Letters of Intent to acquire
NexStar Automation, Inc. of Boulder, Colorado, and Technical Instrument Company
of Sunnyvale, California. Both of these acquisitions not only represent
opportunities to increase our short-term sales and profit growth but, more
importantly, represent the strategic addition of metrology and automation
capability that significantly strengthens your company's ability to provide
production line yield improvement solutions to our high-technology customers.
Both of these acquisitions were completed subsequent to the close of fiscal
1996. NexStar Automation provides parts handling and robotic system solutions
to high-technology industries with a very strong position in the data storage
industry. As additional requirements for parts handling, elimination of operator
intervention and increased measurement throughput are required by our customers,
NexStar's strengths will be invaluable to our future enhanced solutions.
Technical Instrument Company, with a strong position in supplying metrology
systems to mask manufacturers and chip manufacturers in the semiconductor
industry, provides a strong complementary confocal microscopy measurement and
sensor technology to our own interferometric-based measurement strengths. In
addition, Technical Instrument Company's strong position on the West Coast of
the United States and in the Pacific Rim with the semiconductor industry greatly
enhances your company's presence in those areas. Most importantly, the culture
of both these companies mirrors our own -- a customer-comes-first attitude with
innovative technology solutions at the base of each company's offerings. We are
all very excited about the short- and long-term prospects for these new members
of the Zygo family. NexStar's and TIC's solutions are described on pages 5 and
7 of this report.

ADDITIONS TO THE BOARD OF DIRECTORS AND NEW CORPORATE OFFICERS:
Your Board of Directors elected two new corporate vice presidents in January of
this year. William H. Bacon, a 14-year employee with the Company, was elected
Vice President and Director of Corporate Quality, and Robert A. Smythe, a
10-year employee, was elected Vice President and Director of Marketing and
Sales. Both of these gentlemen have enjoyed outstanding careers with the Company
assuming a number of positions of increasing responsibility throughout their
careers. In May of this year, we had the pleasure of announcing the election of
John R. Rockwell to our Board of Directors. Mr. Rockwell is a seasoned
executive, entrepreneur, and advisor to a broad range of companies and
industries. He spent most of his career as a senior executive with Booz, Allen &
Hamilton, a worldwide consulting organization with particular focus on
innovative problem solving and strategic planning. As your company continues its
transition and establishes itself as a value generating growth corporation,
John's advice and counsel will be most valuable to our future Board
deliberations.

OUTLOOK:  As we closed our fiscal year, we were quite pleased to receive
notification of two prestigious awards in recognition of the design, development
and introduction of our new Pegasus 2000 Flying Height Test System. This
product, introduced at the September 1995 Diskcon exhibition, received both the
Photonics Circle of Excellence Award and the R&D 100 award for technology
innovation. Pegasus 2000, another product in our family of on-line yield and
production improvement solutions, is expected to generate incremental revenues
and profits during fiscal 1997.

Although no one can predict the macro-economic forces that ultimately drive the
capital spending demands of the industries we serve, we do believe our enhanced
product position, our record high backlog, and the strategic complementary
strengths brought by Technical Instrument Company and NexStar Automation
position us well to take advantage of whatever demand exists for our products
and systems going forward. In addition, never being complacent, we will continue
to make the necessary strategic investments in new technology and product
developments and in our marketing and customer support infrastructure as we
endeavor to ensure that we have the appropriate solutions and customer support
organizations to optimize our performance long-term.

You, of course, can continue to count on our best efforts as we chart the future
course for your company. As always, we thank you for your continued support of
and interest in your company.

Sincerely,


GARY K. WILLIS

powerful electronics, finer print quality, higher-efficiency diesel engines,
and laser fusion research all share a common element -- finer control of
critical dimensional tolerances at ever-increasing production rates.

As performance demands continue to increase, the dimensional tolerances of key
components in these products get proportionally more stringent. To achieve
critical dimensional tolerances in a production environment, key manufacturing
processes must be continually refined, and their performance monitored.

Since the Company's founding, Zygo's instrumentation and optical component
products have performed at the leading edge of precision. First marketed to the
precision optics industry, and later to data storage device and semiconductor
equipment manufacturers, Zygo measurement technology has proven to be the
definitive solution for fast and accurate measurement and process monitoring in
precision manufacturing facilities.

Further, to expand the reach of our measurement technologies into new and
growing markets, and deeper into existing markets, we are continually expanding
the measurement range of our products to measure surfaces that were previously
either too fine, or too rough, to measure. Similarly, in response to the trend
toward producing precision components in mass quantities, established Zygo
products are adapted, and new products created, for use in high volume
production measurement and analysis.

Two key industries that have embraced Zygo's measurement and process monitoring
expertise are manufacturers of data storage devices and semiconductor production
equipment.

DATA STORAGE INDUSTRY

An example of high-precision components manufactured in high volume are the
minute read/write heads used in hard disk drives found in all computer systems.
Read/write heads transfer data onto, and off of, the surface of a spinning hard
disk platter. To prevent friction and wear, the read/write head "flies" above
the disk's surface on a thin cushion of air. To maintain the proper flying
height, and ensure optimum performance and reliability, the surface of both the
read/write head, and the hard disk, must be made with extremely high precision.

When Zygo first started working with leading disk drive manufacturers, there
were no off-the-shelf instruments for measuring the components that drive makers
needed to measure, at the production rates they needed. It was through the
application of our core technologies -- accurate, noncontact measurement,
flexible and accurate data analysis software, and process automation -- that we
were able to satisfy the measurement requirements of this rapidly growing
industry, and satisfy them beyond expectation. With Zygo's precision measuring
instruments on their production lines, drive makers are now able to verify the
critical surface shape and surface structure of components they produce.

equipment to store and retrieve data. Zygo primarily  serves the hard disk
drive segment of  this industry.

Air Bearing Surface
 The flying height of a  magnetic read/write head is controlled by the shape of
the head's  air bearing surface. By precisely controlling the characteristics of
the air bearing surface, manufacturers can produce disk drives with higher
storage capacities and greater reliability.

Flying Height
 The read/write heads used in computer hard disk drives do not  actually touch
the surface of the disk. Instead they "fly" above the  surface on a cushion of
air. The gap between the head and the disk  is known as the flying height.

<PAGE>

The data storage industry relies on several Zygo products on their production
lines: the Automated Air Bearing Surface Inspection System for measuring
critical parameters on over 20,000 read/write heads per day, the NewView 100
for measuring the recession of the tiny electromagnetic pole tips on the
read/write heads, the Vista system for automatically finding and measuring
contaminants and other defects on heads, the Pegasus 2000 Flying Height Tester
for measuring the flying height performance of read/write heads, and the GPI
interferometer system for measuring the flatness of in-process disk platters.

As a result, manufacturers have increased the precision of disk drive
components, and now pack a huge amount of data into a very small space, while
still reducing the selling price. Pursuing our focus on high-volume automated
inspection systems, Zygo recently acquired NexStar Automation, a company
renowned for expertise in reliable, precision, production automation equipment
and integration in several high-tech industries, including the data storage and
semiconductor industries. NexStar offers creative turnkey solutions for parts
automated production situations, integrating off-the-shelf components into
ingenious time- and money-saving production systems. Together, we will pursue
projects that will greatly increase the throughput of automated inspection
equipment.

Surface Shape / Surface Structure
 Overall surface contours are known as the shape, and the texture
characteristics that make up the surface are known as the structure.  As an
analogy, the hills and valleys of a road are surface shape; the texture of the
paving material is surface structure.

Interferometer
 Interferometry is a  measurement technique employed in several Zygo instruments
where a beam of light, reflected off of the item being measured, is combined
with a reference beam of light. By analyzing the optical interaction that
occurs between these two beams, Zygo instruments accurately measure distance,
angle, and three-dimensional topography.

SEMICONDUCTOR INDUSTRY

With the exponential rise in the popularity of personal computers, and the
integration of microelectronics into everything from computers to household
items like vacuum cleaners and dishwashers, the demand for increasing the
precision, production volume, and reliability of semiconductor chips is growing
at unprecedented rates.

Semiconductor manufacturing is an extremely precise process. Integrated circuit
chips (IC's) are formed on thin silicon wafers about eight inches in diameter.
The wafer is then "diced" and the individual chips are placed into the
"packages" that are mounted to circuit boards.

The process of forming the chips on the semiconductor wafers is done with
step-and-repeat photolithography systems, or "steppers," that print the
microscopic circuits onto photoresistive material in many layers. The
positioning accuracy (measured in nanometers) of these steppers is extremely
critical. Many of the steppers employ Zygo's ZMI-1000 Displacement Measuring
Interferometer System. Position information, measured by the ZMI system with
low-power laser beams, is relayed back to the components which control the
position of the translation stages, thus allowing them to move the wafer to
exactly the right position. The ZMI provides the high degree of measurement
accuracy required for these operations, and has proven itself to be very
reliable on high-volume production lines, running 24 hours a day.

Another critical aspect of the position-measurement system is the precision
mirrors which redirect the ZMI's measurement beams to the intended targets. The
surface of these mirrors must be essentially perfect; any variation in the
reflected laser beam would cause serious positioning errors, resulting in
unusable IC's. Zygo's Custom Optics Group has many years of experience in
producing these types of precision surfaces using CNC machining and proprietary
finishing techniques, which have helped make us a leading supplier of these
mirrors.

To further our ability to serve this growing industry, Zygo recently acquired
Technical Instrument Company (TIC) whose confocal scanning optical microscope
(CSOM) products and systems are widely used in the semiconductor industry for
wafer mask inspection. As a pioneer in CSOM white light imaging, TIC opened the
door to cost- effective realtime submicron imaging. TIC's microscope technology
is an excellent complement to Zygo's interferometric microscope products and
capabilities, and broadens our abilities to provide enhanced measurement and
yield management solutions to our customers. In addition, TIC's strong
relationships with semiconductor manufacturers on the West Coast and Pacific
Rim will greatly strengthen our presence, and our ability to serve customers,
in those areas.

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

RESULTS OF OPERATIONS

FISCAL 1996 COMPARED TO FISCAL 1995
Net sales of $53,478,000 for fiscal 1996 increased by $21,245,000 or 65.9% from
fiscal 1995 net sales of $32,233,000. The increase in net sales in fiscal 1996
was principally due to increased demand for the Company's instruments and
systems from manufacturers of data storage, semiconductor, and other high
technology products. Net sales of the Company's electro-optical instruments,
systems and accessories in fiscal 1996, which accounted for 87.2% of total
fiscal 1996 net sales, increased by 71.9% from fiscal 1995. Net sales of
precision optical components increased by 34.0% in fiscal 1996 from the prior
year.

The Company's sales outside the United States amounted to $26,807,000 in fiscal
1996, an increase of $11,826,000 or 78.9% from fiscal 1995. Sales in Japan
during fiscal 1996 amounted to $19,763,000, an increase of $10,133,000 over
fiscal 1995. The significant increase was due to the improving Japanese economy
and the improved demand for the Company's instruments and systems, including its
motion control systems which are sold to Canon for incorporation into their
step-andrepeat photolithography systems used in semiconductor manufacturing,
as well as the Company's other electro-optical systems which are sold to Canon
for resale in the domestic Japanese market or used by Canon in their facilities.
Sales to other geographic markets outside the U.S. amounted to $7,044,000 in
fiscal 1996, an increase of $1,693,000 from fiscal 1995. The 31.6% increase was
principally the result of a continuation of strong sales of the Company's
electro-optical instruments, systems and accessories to the data storage and
semiconductor manufacturing industry in the Pacific Rim and increased sales in
Europe.

Substantially all of the Company's sales and costs are negotiated and paid in
U.S. dollars. Significant changes in the values of foreign currencies relative
to the value of the U.S. dollar can impact the sales of the Company's products
in its export markets as would changes in the general economic conditions in
those markets. The impact of such changes in foreign currency values on the
Company's sales cannot be measured.

Gross profit in fiscal 1996 amounted to $24,844,000, an increase of $10,613,000
(74.6%) over gross profit of $14,231,000 in fiscal 1995. As a percentage of net
sales, gross profit in fiscal 1996 was 46.5%, as compared to 44.2% in fiscal
1995. Gross profit dollars and gross profit as a percent of net sales increased
principally due to the increased volume of sales from electro-optical
instruments, systems and accessories, precision optical components, and customer
support, combined with volume-related manufacturing efficiencies.

Selling, general and administrative expenses in fiscal 1996 of $8,305,000
increased by $1,768,000 from fiscal 1995. The increase was principally a result
of volume-related expenses, such as commissions, allowance for doubtful
accounts, and product marketing expenses (34.3% of increase) and necessary
infrastructure changes made to support the growth of the business such as
additions to sales and marketing personnel. As a percentage of net sales,
selling, general and administrative expenses declined in fiscal 1996 to 15.5%,
as compared to 20.3% in fiscal 1995, principally due to the 65.9% growth in net
sales.

Research and development costs in fiscal 1996 totaled $5,538,000 and increased
by $1,571,000 or 39.6% from fiscal 1995. The increase in R&D expenses primarily
resulted from spending on personnel and materials at both the Company's
principal R&D center in Middlefield, Connecticut, and its R&D facility in Simi
Valley, California, which was formed during the second half of fiscal 1995. As
a percentage of net sales, research and development costs were 10.4% and 12.3%
in fiscal 1996 and fiscal 1995, respectively.

In fiscal 1996, the Company had operating profit of $11,001,000 as compared to
$3,727,000 in fiscal 1995. Operating profit as a percentage of net sales in
fiscal 1996 improved to 20.6% from 11.6% in fiscal 1995. Interest income in
fiscal 1996 amounted to $939,000 and was $567,000 higher than in fiscal 1995.
This increase was primarily due to higher cash balances, principally as a
result of the sale by the Company of 845,000 shares of its common stock in a
secondary offering which generated approximately $22.7 million in net proceeds
to the Company.

Backlog at June 30, 1996, was $19,147,000 compared to $12,993,000 at June 30,
1995. The $6,154,000 or 47.4% increase in backlog was primarily a result of
stronger demand for all of the Company's electrooptical instruments and
accessories. The backlog of the Company's electro-optical instruments and
accessories at June 30, 1996, increased $5,321,000 (57.8%) from that at June 30,
1995. The backlog of the Company's precision custom optical components increased
by $833,000 (22.0%) from the year earlier as a result of improved demand for
precision optical components.

The Company reported net earnings and earnings per common and common equivalent
share of $7,931,000 and $1.53, respectively, in fiscal 1996 as compared to
$2,749,000 and $.65 per share in fiscal 1995. This was an increase in net
earnings and earnings per share of $5,182,000 (188.5%) and $.88 (135.4%),
respectively, over fiscal 1995.

FISCAL 1995 COMPARED TO FISCAL 1994
Net sales of $32,233,000 in fiscal 1995 increased from fiscal 1994 net sales by
$8,092,000 or 33.5%. The principal reason for the significant increase was
additional sales of the Company's electro-optical instrument products primarily
resulting from an improved economic climate in certain industry segments, most
notably semiconductor and data storage (disk drive) manufacturing, and from the
introduction of a new fully-automated electro-optical instrument product used
by data storage industry customers to improve the yield of their manufacturing
processes. These increases were partially offset by a decline of $340,000 in R&D
contract revenues resulting from the completion in fiscal 1994 of a research
and development contract and lower sales of the Company's precision custom
optical components, which declined by $313,000 or 5.8% from the year earlier.

The Company's sales outside the United States amounted to $14,981,000 in fiscal
1995, an increase of $3,934,000 from fiscal 1994. Sales in Japan during fiscal
1995 amounted to $9,630,000, an increase of $2,044,000 over fiscal 1994. This
increase resulted primarily from an increase in product sales in Japan in fiscal
1995 of over 33% when compared to product sales in fiscal 1994, partially offset
by the absence in fiscal 1995 of R&D contract revenues. The significant increase
in product sales was primarily due to the improving Japanese economy and the
strengthening of the semiconductor equipment market served by Canon Inc. and
Canon Sales Co., Inc., the Company's exclusive distributor in Japan. Sales to
other geographic markets outside the U.S. amounted to $5,351,000 in fiscal 1995,
a $1,890,000 increase from fiscal 1994. The 55% increase was principally the
result of strong sales of the Company's electro-optical instruments to the data
storage and semiconductor manufacturing industry in the Pacific Rim and
increased sales in Europe as a result of an improved general economic climate
there.

Gross profit in fiscal 1995 amounted to $14,231,000, an increase of $3,615,000
(34.1%) over gross profit in fiscal 1994, principally due to the increase in
sales and a slight improvement in gross profit margins on actual shipments. As
a percentage of sales, gross profit in fiscal 1995 was 44.2%, as compared to
44.0% in fiscal 1994.

Selling, general and administrative expenses in fiscal 1995 decreased by
$138,000 from fiscal 1994. As a percentage of sales, selling, general and
administrative expenses were 20.3% and 27.7% in fiscal 1995 and fiscal 1994,
respectively. Selling expenses, including salaries, advertising, and sales
promotion expenses related to the Company's electro-optical instrument products
as well as commissions on higher sales, increased $307,000 from fiscal 1994.
Administrative expenses decreased by $445,000, principally as a result of
reduced legal expenses. Additional administrative cost reductions reflected the
completion of the implementation of a Business Management Information System
and strict cost controls.

Research and development costs in fiscal 1995 totaled $3,967,000 and increased
by $1,181,000 or 42.4% from fiscal 1994. The increase was principally the result
of spending associated with the creation and operation of an R&D facility in
Simi Valley, California, focused on designing and developing production-oriented
test and measurement products for the data storage industry. Additionally, the
amount of expense incurred in fiscal 1995 at the Company's Middlefield,
Connecticut, facility increased from fiscal 1994 to support several R&D projects
there. As a percentage of sales, research and development costs were 12.3% and
11.5% in fiscal 1995 and 1994, respectively.

In fiscal 1995, the Company had operating profit of $3,727,000 (11.6% of net
sales) as compared to $1,155,000 (4.8% of net sales) in fiscal 1994. The 222.7%
improvement resulted principally from higher gross profit from increased sales
volume, partially offset by the increase in R&D expense.

Interest income in fiscal 1995 amounted to $372,000 and was $34,000 higher than
fiscal 1994, principally due to generally higher interest rates on the Company's
marketable securities and short-term cash investments. Interest expense
decreased in fiscal 1995 by $11,000 from $51,000 in fiscal 1994 primarily as a
result of lower average principal balances on the Company's long-term debt,
which was fully repaid in the quarter ended March 31, 1995.

Backlog at June 30, 1995, was $12,993,000 compared to $3,782,000 at June 30,
1994. The $9,211,000 increase in backlog was primarily a result of strong
demand for all of the Company's electro-optical instrument products,
particularly its distance measuring interferometers used in precision motion
control applications such as microlithography in semiconductor and flat-panel
display manufacturing and its microscope products used in a variety of
industrial applications, most notably in the production of read/write heads in
the data storage industry. The backlog of the Company's electrooptical
instruments and accessories at June 30, 1995, increased $7,355,000 or nearly
400% from that at June 30, 1994. The backlog of the Company's precision custom
optical components increased by $1,834,000 (94%) from the year earlier as a
result of improved demand for sophisticated optical components.

The Company reported net earnings and earnings per common and common equivalent
share of $2,749,000 and $.65, respectively, in fiscal 1995 as compared to
$918,000 and $.23 per share in fiscal 1994.

MANAGEMENT'S DISCUSSION AND ANALYSIS (CONTINUED)

LIQUIDITY AND CAPITAL RESOURCES
At June 30, 1996, working capital was $46,756,000, an increase of $29,684,000
from the amount at June 30, 1995, and the Company had cash and cash equivalents
of $17,945,000 and marketable securities amounting to $20,035,000 for a total of
$37,980,000. The $27,806,000 increase in cash and cash equivalents and
marketable securities from the amount at June 30, 1995 was due primarily to the
secondary offering of 1,300,000 shares of the Company's common stock, of which
845,000 shares were sold by the Company. This sale generated approximately
$22.7 million in net proceeds to the Company. Principally as a result of the
growth in the Company's net sales, trade receivables increased by $3,566,000,
and inventory increased by $1,391,000 from the amounts at June 30, 1995. The
receivables increase was due primarily to the significant growth in net sales
in the second half of fiscal 1996 which were $10,206,000 higher than the same
period in fiscal 1995, partially offset by aggressive collections within the
last half of the fiscal year. Inventory increased primarily due to necessary
inventory to support the growth in sales of the Company's electro-optical
instruments. Accounts payable and accrued expenses increased by $3,256,000 in
fiscal 1996 to $9,921,000, principally as a result of the increase in
inventories and other costs associated with the growth of the business. The
Company's expenditures for property, plant and equipment totaled $2,758,000 in
fiscal 1996 which was $1,127,000 more than the prior fiscal year. Capital
expenditures were principally for machinery and equipment for capacity additions
and productivity improvement in the optical manufacturing facility and personal
computers and other materials supporting the Company's research and development
activities. Additionally, on January 4, 1996, the Company purchased
approximately 22 acres of land adjacent to the Company's facility in
Middlefield, Connecticut, for a purchase price of $440,000. The land,  which was
jointly owned by Paul F. Forman, Sol F. Laufer, and Carl A. Zanoni, founders of
the Company, will facilitate expansion of the Company's buildings and/or parking
facilities in the future. As of June 30, 1996, there were no borrowings
outstanding under the Company's $3,000,000 bank line of credit. Unused amounts
under the line of credit are available for short-term working capital needs.
Stockholders' equity at June 30, 1996, increased by $31,091,000 from the year
earlier to $53,424,000 reflecting primarily net income of $7,931,000, and
increases in the Company's common stock and paid-in capital accounts resulting
from the Company's secondary stock offering.

Subsequent to the close of fiscal 1996 and effective August 8, 1996, the Company
acquired Technical Instrument Company ("TIC"), a privately held California based
entity that designs, manufactures, markets and sells microscope systems and
other precision optical instrument systems and components. The Company paid
approximately $11.7 million in cash and issued unregistered shares of its common
stock, $.10 par value, valued at $3.0 million in exchange for all the
outstanding capital stock of TIC. The transaction will be accounted for as a
purchase. TIC's revenues for the twelve months (pro forma unaudited) ended June
30, 1996 were approximately $11.1 million.

Additionally, effective September 12, 1996, the Company acquired NexStar
Automation, Incorporated ("NexStar"), a Canadian company that was publicly
traded on the Vancouver Stock Exchange. NexStar is engaged in the business of
designing, developing, and manufacturing automation and parts handling equipment
to improve production efficiency and manufacturing yields within the data
storage, semiconductor, and medical disposals markets. The Company acquired all
the outstanding stock and stock equivalents of NexStar in exchange for 250,000
shares of the Company's common stock. The transaction will be accounted for as a
pooling-of-interests. NexStar's revenues for the year ended December 31, 1995
were approximately $2.6 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 1996, 1995, AND 1994


NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its wholly owned Foreign Sales Corporation ("FSC") subsidiary. The Company also
owns 100% of Zygo Credit Corporation which was formed in fiscal 1983. Activity
of Zygo Credit Corporation has been insignificant to date. All material
transactions and accounts with the subsidiaries have been eliminated from the
consolidated financial statements.

CASH AND CASH EQUIVALENTS

The Company considers cash and cash investments with maturities at the date of
purchase of less than three months to be cash and cash equivalents.

MARKETABLE SECURITIES

The Company considers investments in securities with maturities at the date of
purchase in excess of three months as marketable securities. Marketable
securities primarily consist of tax-exempt municipal debt securities. The
Company adopted the provisions of Statement of Financial Accounting Standards
No. 115, Accounting for Certain Investments in Debt and Equity Securities
("Statement 115") at June 30, 1994. The change in accounting for Marketable
Securities had no effect on retained earnings. All securities held by the
Company at June 30, 1996, 1995, and 1994 were classified as available-for-sale
and recorded at fair value or held to maturity and recorded at cost. Unrealized
holding gains and losses, net of the related tax effect, on available-for-sale
securities are excluded from earnings and are reported as a separate component
of stockholders' equity until realized.

INVENTORIES

Inventories are stated at the lower of cost (determined on a first-in, first-out
basis) or market.

REVENUE RECOGNITION

Sales, other than sales under long-term research and development contracts, are
recognized when units are shipped. Sales related to long-term fixed-price
research and development contracts are recognized under the cost-to-cost
percentage of completion method of accounting.

DEPRECIATION

Depreciation rates are based on the estimated useful lives of the various
classes of assets and are computed using the straight-line method.

EARNINGS PER SHARE

Earnings per common and common equivalent share amounts represent primary
earnings per share and are based upon the weighted average number of common
shares outstanding, plus, when their effect is dilutive, the weighted average
number of shares issuable upon exercise of outstanding stock options, less the
weighted average number of common shares which could have been repurchased with
the proceeds available from the assumed exercise of the outstanding options.
Fully diluted earnings per share are not significantly different from primary
earnings per share.

GAIN CONTINGENCY

The Company was awarded $2,668,710 plus recovery of certain costs in a judgment
rendered by the United States District Court (District of Arizona) on June 2,
1994. The Court's decision was appealed to the Court of Appeals for the Federal
Circuit located in Washington, D.C. by the defendant and oral arguments of the
appeal were heard by the Court on March 9, 1995. On April 1, 1996, the United
States Court of Appeals for the Federal Circuit rendered an Opinion Announcing
Judgment of the Court. The appellate court affirmed-in-part and reversed-in-part
the District Court's earlier findings and remanded the case to the District
Court for a redetermination of the damage award. The Company has not recorded
any gain from the District Court's earlier ruling and will not until a final
determination of the award is made.

STOCK SPLIT

The Board of Directors of the Company declared a 3-for-2 split of the Company's
common shares, effected in the form of a 50% stock dividend paid on August 21,
1995, to shareholders of record as of the close of business on August 1, 1995.
All presentations involving numbers of shares and amounts per share in 1995 and
prior years have been restated to reflect the stock split.

CAPITAL STOCK

The Company follows the practice of recording amounts received upon the exercise
of options by crediting common stock and additional capital. No charges are
reflected in the consolidated statements of operations as a result of the grant
or exercise of stock options which are granted at fair market value on the date
of grant. The Company realizes an income tax benefit from the exercise or early
disposition of certain stock options. This benefit results in a decrease in
current income taxes payable and an increase in additional capital.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts of cash, accounts receivable, accounts payable, and accrued
expenses approximate fair value because of the short maturity of these items.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

USE OF ESTIMATES

Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from those estimates.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be disposed of
("Statement 121"), was issued in 1995. Statement 121 requires that long-lived
assets to be disposed of, certain identifiable intangibles, and goodwill to be
held and used by an entity be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Statement 121 is effective for the Company's fiscal year 1996. The
Company believes that the adoption of this accounting standard will not have a
material impact on its operating results or financial condition.

Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation ("Statement 123"), was issued in 1995. Implementation is required
in the fiscal year commencing July 1, 1996. Statement 123 established financial
accounting and reporting standards for stock-based compensation plans. The
Company intends to adopt the disclosure requirements of Statement 123 and
continue to account for stock-based compensation under APB Opinion 25. The
implementation of this statement is expected to have no material effect on the
Company's consolidated financial statements.

NOTE 2: MARKETABLE SECURITIES

Marketable securities at June 30, 1996 consist primarily of taxexempt bonds
issued by various state and municipal agencies which are reported at fair value.
The unrealized loss on marketable securities of $58,724 (gross) is shown net of
its related tax effect of $24,151 as a separate component of stockholders'
equity.

Dividend and interest income are recognized when earned. Realized gains and
losses are included in earnings and are derived using the specific
identification method for determining the cost of securities sold.

The cost, gross unrealized holding gains, gross unrealized holding losses, and
fair value for available-for-sale securities at June 30, 1996, June 30, 1995,
and June 30, 1994, were as follows:

The Company recorded gross realized gains on the maturity of investment
securities of $15,611 and $135 in 1996 and 1995, respectively. There were no
gross realized losses recorded in 1996, 1995, or  1994. Maturities of investment
securities classified as available-for-sale were as follows at June 30, 1996:

NOTE 5: PROFIT-SHARING PLAN

The Company maintains a deferred profit-sharing plan under which substantially
all full-time employees of the Company are eligible to participate.
Profit-sharing expense for the years ended June 30, 1996, 1995, and 1994
amounted to $1,295,600, $440,000, and $147,500, respectively. Profit-sharing
contributions are determined annually at the discretion of the Board of
Directors.

Effective June 30, 1985, the existing profit-sharing plan was revised and
amended to incorporate a 401(k) tax deferred payroll deduction program and an
Employee Stock Ownership Program. Under the 401(k), employees may contribute a
tax deferred amount of up to 15% of their compensation, as defined. The Company
may contribute an amount to the 401(k) which amount is determined annually at
the discretion of the Board of Directors. The 401(k) contribution expense for
the years ended June 30, 1996, 1995, and 1994 amounted to $333,900, $255,000,
and $146,400, respectively.

Under the Employee Stock Ownership Program, the Company may, at the discretion
of the Board of Directors, contribute its own stock or cash to purchase its own
stock. Such stock's fair market value shall not exceed the maximum amount of
employee stock ownership credit as determined under Section 416 of the Internal
Revenue Code. There were no purchases and no contributions made under this
program for the years ended June 30, 1996, 1995, and 1994.


NOTE 6: STOCKHOLDERS' AGREEMENT

A Registration Rights Agreement was entered into by Canon Inc., Wesleyan
University, Paul F. Forman, Carl A. Zanoni, Sol F. Laufer, and the Company, in
November 1993, granting to each of these stockholders the right, until November
30, 1998, to have his or its shares of Common Stock included in any registered
public offering of the Company's securities.


NOTE 7: STOCKHOLDERS' EQUITY

On July 20, 1995, the Board of Directors declared a 3-for-2 split effected in
the form of a 50% stock dividend payable on August 21, 1995, to shareholders of
record on August 1, 1995. This transaction resulted in the issuance of
approximately 1,309,000 additional shares of Common Stock. Stockholders' Equity
had been adjusted to recognize the effect of the stock split by reclassifying
from retained earnings to paid-in capital the par value of the additional shares
arising from the split. In addition, all references in the financial statements
to numbers of shares, per share amounts, stock option data, and market prices
of the Company's Common Stock have been restated to give retroactive recognition
to the stock split.

On July 20, 1995, the Board of Directors approved an increase in the authorized
shares of the Company's Common Stock from 10,000,000 to 15,000,000, which was
approved by the Company's stockholders at its annual meeting held on November
16, 1995. On December 13, 1995, the Company commenced a public offering of
1,300,000 shares of Common Stock, of which 845,000 shares were sold by the
Company, and 455,000 shares were sold by certain of the Company's stockholders.
The Company generated approximately $22.7 million in net proceeds, which is
expected to be used for working capital associated with expanded sales, research
and development and other general corporate purposes, and for potential
acquisitions (see note 12).


NOTE 8: STOCK OPTIONS AND STOCK OWNERSHIP PLANS

On September 3, 1987, the Board of Directors adopted a non-qualified stock
option plan (the "Non-Qualified Plan") providing for nonqualified options to
purchase Common Stock of the Company and reserved 300,000 shares of Common Stock
for issuance upon the exercise of options under the Non-Qualified Plan. During
fiscal year 1990, the amount of shares reserved under the Non-Qualified Plan was
increased to 600,000. On August 26, 1992, the Board of Directors amended and
restated the Non-Qualified Plan and increased the amount of shares reserved to
975,000. On November 19, 1992, the Amended and Restated Non-Qualified Stock
Option Plan (the "Amended and Restated Non-Qualified Plan") was approved by the
Company's stockholders. On August 24, 1995, the Board of Directors approved an
increase in the number of shares authorized under this plan from 975,000 to
1,425,000, which was approved by the Company's stockholders at its annual
meeting held on November 16, 1995. At June 30, 1996, options to purchase 652,337
shares of Common Stock, at prices of $2.50 to $31.88 per share, were outstanding
under the Amended and Restated Non-Qualified Plan of which options to purchase
354,157 shares were exercisable. Options exercised during fiscal 1996, 1995, and
1994 were 43,200 shares at $2.50 to $8.50 per share; 38,250 shares at $2.50 to
$4.00 per share; and 2,588 shares at $2.83 to $3.83 per share, respectively. At
June 30, 1996, there were 488,470 Common Shares reserved for future issuance of
stock options under the Amended and Restated Non-Qualified Plan.

On August 25, 1994, the Board of Directors adopted a Non-Employee Director Stock
Option Plan providing for non-qualified options to purchase Common Stock of the
Company and reserved 300,000 shares of Common Stock for issuance upon the
exercise of options under the NonEmployee Director Stock Option Plan.

At June 30, 1996, options to purchase 225,000 shares of Common Stock, at a
price ranging from $4.00 to $54.75 per share, were outstanding under the
Non-Employee Director Stock Option Plan; 37,500 of which were exercisable.

During fiscal 1994, the Internal Revenue Service completed an examination of the
Company's fiscal 1991 U.S. federal income tax return. Adjustments to the fiscal
1991 income tax return generated deferred tax benefits which the Company has
received or expects to receive in subsequent years.

Income taxes paid amounted to $3,403,300 (including cash payments of $3,096,200
and $307,100 of prior year overpayments applied to fiscal 1996), $793,100 and
$1,185,000 (including additional taxes owed for fiscal 1991), in fiscal 1996,
1995, and 1994, respectively.

The total income tax expense differs from the amount computed by applying the
applicable U.S. federal income tax rate of 34% to earnings before income taxes
for the following reasons:

A valuation allowance has not been recorded because the Company believes that
the deferred tax assets will, more likely than not, be realized. This
determination is based largely upon the Company's historical earnings trend as
well as its ability to carryback reversing items and recover taxes paid in the
carryback period. In addition, the Company has the ability to offset deferred
tax assets against deferred tax liabilities associated with such items as
depreciation and amortization.

On January 4, 1996, the Company purchased approximately 22 acres of land
adjacent to the Company's facility in Middlefield, Connecticut, for a purchase
price of $440,000. The land, which was jointly owned by Paul F. Forman, Sol F.
Laufer, and Carl A. Zanoni, founders of the Company, will facilitate expansion
of the Company's buildings and/or parking facilities in the future.


NOTE 12: SUBSEQUENT EVENTS

Effective August 8, 1996, the Company acquired Technical Instrument Company
("TIC"), a privately held California based entity that designs, manufactures,
markets and sells microscope systems and other precision optical instrument
systems and components. The Company paid approximately $11.7 million in cash
and issued unregistered shares of its common stock, $.10 par value, valued at
$3 million in exchange for all the outstanding capital stock of TIC. The
transaction will be accounted for as a purchase. TIC's revenues for the twelve
months (pro forma unaudited) ended June 30, 1996 were approximately $11.1
million.

Additionally, the Company is in the process of finalizing an agreement to
acquire NexStar Automation, Incorporated ("NexStar"), a Canadian company that
is publicly traded on the Vancouver Stock Exchange. NexStar is engaged in the
business of designing, developing, and manufacturing automation and parts
handling equipment to improve production efficiency and manufacturing yields
within the data storage, semiconductor, and medical disposals markets. The
Company will acquire all the outstanding stock and stock equivalents of NexStar
in exchange for 250,000 shares of the Company's common stock. The transaction
will be accounted for as a pooling-of-interests. NexStar's revenues for the year
ended December 31, 1995 were approximately $2.6 million.

REPORT OF INDEPENDENT AUDITORS

THE BOARD OF DIRECTORS AND STOCKHOLDERS OF ZYGO CORPORATION:
We have audited the accompanying consolidated balance sheets of Zygo Corporation
and consolidated subsidiary as of June 30, 1996 and 1995, and the related
consolidated statements of earnings, stockholders' equity and cash flows for
each of the years in the three-year period ended June 30, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Zygo Corporation and
consolidated subsidiary as of June 30, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period
ended June 30, 1996, in conformity with generally accepted accounting
principles.
