   ITEM 1.  BUSINESS

   CORPORATE PROFILE

        Cognex(R) Corporation ("Cognex" or the "Company," each of which term
   includes, unless the context indicates otherwise, Cognex Corporation and its
   subsidiaries) was incorporated in Massachusetts in 1981. Its principal
   executive offices are located at One Vision Drive, Natick, Massachusetts
   01760 and its telephone number is (508) 650-3000.

        The Company designs, develops, and markets a family of machine vision
   systems that are used to replace human vision in a wide range of
   manufacturing processes. These high-level systems consist of sophisticated
   image analysis software and high-speed, special-purpose computers (vision
   engines) which, when connected to a video camera, interpret and generate
   information about video images. For example, a Cognex machine vision system
   can locate an object, read alphanumeric characters, detect flaws, or measure
   dimensions.

        Machine vision systems are used in a variety of industries including the
   semiconductor, electronics, automotive, consumer products, packaging,
   pharmaceutical, metals, plastics, and paper industries. Machine vision is
   important for applications in which human vision is inadequate due to
   fatigue, visual acuity, or speed, or in instances where substantial cost
   savings are obtained through the reduction of direct labor and improved
   product quality. Today, many types of manufacturing equipment require machine
   vision because of the increasing demands for speed and accuracy in
   manufacturing processes, as well as the decreasing geometries of items being
   manufactured.

   WHAT IS MACHINE VISION?

        In a typical machine vision application, a video camera positioned on
   the production line captures an image of the part to be inspected. The
   machine vision computer then uses sophisticated image analysis software to
   extract information from the image and provide an answer to a question.
   Cognex machine vision systems can answer four types of questions:

     IDENTIFICATION
     --------------
     What is it?           Identifying an object by analyzing     Identifying the serial number on an automotive
                           its shape or by reading a serial       airbag so that it can be tracked and processed
                           number on it.                          correctly through manufacturing.

     INSPECTION
     ----------
     How good is it?       Inspecting an object for flaws or      Inspecting the quality of printing on
                           defects.                               pharmaceutical labels and packaging.

     GAUGING

     What size is it?      Determining the dimensions of an       Determining the diameter of a bearing prior to
                           object.                                final assembly.


        Once the machine vision system has processed the image and performed any
   necessary analysis, the result is then communicated to other equipment on the
   factory floor, such as an industrial controller, a robotic arm, a deflector
   which removes the part from the line, a positioning table which moves the
   part, or alternatively, to a computer file for analysis or subsequent process
   control. This process is repeated during the manufacturing process as product
   moves into position in front of the camera. Machine vision systems can
   perform inspections quickly enough to keep pace with machines that process
   thousands of items or material feet per minute, thus increasing both quality
   and productivity.

   THE MACHINE VISION MARKET

        The machine vision market can be segmented into two categories: original
   equipment manufacturers (OEMs) and the factory floor. The factory floor can
   be further subdivided between system integrators and end users. OEMs are
   companies that build standard products sold as capital equipment for the
   factory floor. These customers, most of which are in the semiconductor and
   electronics industries, have the technical expertise to build Cognex's
   programmable, board-level machine vision systems directly into their products
   which are then sold to end users.

        System integrators are companies that create complete, automated
   inspection solutions for end users on the factory floor in a variety of
   industries. For example, they combine lighting, conveyors, robotics, machine
   vision, and other components to produce custom inspection systems for various
   applications. Because system integrators encounter a broad range of
   automation problems, they purchase a variety of Cognex products, from
   programmable systems to application-specific solutions tailored to solve
   particular manufacturing tasks.

        End users are companies that manufacture products, such as radios,
   telephones, ball-point pens, metals, and paper on the factory floor. While
   they may purchase capital equipment containing machine vision or hire a
   system integrator to build an inspection system, many end users choose to
   purchase machine vision directly to solve specific applications on their
   production lines. Unlike OEMs and system integrators, these customers
   typically have little or no computer programming or machine vision
   experience.

   BUSINESS STRATEGY

        The Company's goal is to expand its position as a leading worldwide
   supplier of machine vision systems for factory automation. Currently, the
   Company's products are designed for factory automation because the Company
   believes that this market offers the greatest opportunity for selling high
   value-added, standard products in high volume. Within the factory automation
   market, the Company has historically focused primarily on those customers who
   must have machine vision because of the increasing complexity of their
   products or manufacturing methods.


                                       2
   4
        Emphasizing high value-added products and applications is important to
   the Company's strategy because not every segment of the machine vision market
   offers opportunity for sustained profitability. High value-added is realized
   in the Company's products in several ways. The primary value-added is derived
   from offering unique vision software algorithms which solve challenging
   problems better than competing products. The other major mode of realizing
   high value-added is by offering products which are complete solutions to
   known problems, incorporating all of the necessary vision software,
   applications software, hardware, and electro-optics. Both modes of realizing
   high value-added require the Company to maintain an industry-leading level of
   investment in research, development and engineering.

        Within the factory automation market, the Company has tailored its
   product and support offerings to match the characteristics of its two major
   segments: OEMs and the factory floor. Historically, the OEM segment has been
   the source of the majority of the Company's sales. However, the Company
   believes that the factory floor segment has the potential in the long term to
   be larger than the OEM segment. Consequently, the Company has invested in
   developing and acquiring products which meet the needs of the factory floor
   market and in developing a strong worldwide direct sales and support
   infrastructure. The Company will continue to invest in both segments of the
   market, defending its strong position in the OEM segment while expanding in
   the factory floor segment.

         The Company has historically pursued a global business strategy,
   investing in building a strong direct presence in North America, Japan,
   Europe, and Southeast Asia. In 1997, approximately 62% of the Company's
   revenue came from markets outside of the United States. In all of these
   regions, the Company is acknowledged to be a leading machine vision supplier.
   The Company intends to continue to invest in the expansion of direct sales,
   support, local marketing, and local engineering in these regions.

        The factory automation market for machine vision is comprised of many
   market niches defined by differing application requirements, industries, and
   cost/performance criteria. The Company's business strategy includes selective
   expansion into other industrial machine vision applications which will be
   driven both by the internal development of new products and the acquisition
   of companies and technologies. In July 1995, the Company acquired Acumen,
   Inc., a developer of machine vision systems for semiconductor wafer
   identification. In February 1996, the Company acquired Isys Controls, Inc., a
   developer of high-performance machine vision systems for high-speed surface
   inspection. In July 1997, the Company acquired Mayan Automation, Inc., a
   developer of intelligent camera-based machine vision systems for surface
   inspection. These acquisitions gave Cognex an immediate and strong presence
   in the growing niche markets for semiconductor wafer identification and
   surface inspection.

   PRODUCTS

        The Company develops and sells a wide range of machine vision products.
   These products fall into two lines: the Modular Vision System (MVS) Product
   Line and the Surface Inspection System (SIS) Product Line. The Company
   estimates that it had sold approximately 70,000 machine vision systems as of
   December 31, 1997.

        The MVS Product Line consists of an integrated family of proprietary
   vision software components together with vision hardware components (embedded
   vision engines and frame grabbers) which require minimal customization and
   support by the Company. Modular Vision Systems sold by the Company are
   defined as either general-purpose or application-specific products.
   General-purpose machine vision products enable customers to solve a wide
   range of problems by selecting the tools necessary to solve their vision
   problem from the Company's vision software library and then configuring their
   solution by utilizing a programmable language or a "point-and-click"
   interface. Application-specific machine vision products are "packaged"
   combinations of software and hardware that are designed to solve targeted
   problems without any customization by the Company or its customers. A typical
   Cognex Modular Vision System, including software and hardware, ranges in
   price from $7,500 to $20,000.


                                       3

          The SIS Product Line consists of a family of intelligent line-scan
   cameras, high-performance image processing hardware, special-purpose
   illumination systems, and proprietary defect detection and classification
   software. These elements are combined into complete systems which range in
   price from $25,000 to $2,500,000, depending upon the number of cameras and
   the processing speed. The Company's Surface Inspection Systems are
   application-specific products intended to solve surface inspection problems
   within a targeted set of industries and applications without any
   customization by the Company or its customers.

        MODULAR VISION SYSTEM PRODUCT LINE

        Programmable Vision Systems

        Cognex Programmable Vision Systems (PVSs) are board-level vision systems
   programmable in C-language. PVSs are comprised of software and hardware
   "building blocks" that enable customers to construct solutions tailored to
   their application needs. The Company offers a library of vision software
   tools that locate patterns, inspect for defects, measure geometric
   properties, and identify parts. The hardware is a family of embedded vision
   engines and frame grabbers.

        Embedded vision engines are vision computers which plug into the
   backplane of a standard personal computer (PC) or VME bus architecture. Each
   embedded vision engine contains an on-board central processing unit (CPU),
   image capture mechanism, memory, and input/output connector, enabling the
   host computer to off-load all vision tasks to the vision processor. Frame
   grabbers are single-board image capture devices which capture images from
   video cameras and input the images directly into the host CPU over a standard
   bus, such as a PCI. In this case, the Cognex vision software tools run
   directly on the PC's CPU.

        Customers first choose the most appropriate software tools from the
   vision software library and then select the hardware platform that satisfies
   their speed and price requirements. To create a vision solution, users write
   a C-language program that connects the software blocks appropriate for their
   vision tasks and then run the application on the selected hardware platform.
   Customers are given the flexibility to configure their own vision solutions
   to a broad range of complex vision problems without detailed support from the
   Company. Cognex vision hardware is functionally and software compatible
   across product lines, allowing customers to readily upgrade to higher
   performance systems or to change platforms as their application needs change.

        In 1997, the Company introduced the Cognex MVS 8000 Series which
   includes both embedded vision engines and frame grabbers, as well as new
   vision software tools which offer improvements in accuracy and robustness.
   The 8000 Series is designed to exploit the power of Intel MMX-based
   processors, Microsoft Windows/NT operating systems, and high-speed PCI
   bus-based PCs. The Company also offers the Cognex 4000 Series which plugs
   directly into a VME backplane, as well as the Cognex 5000 and 6000 Series
   which run on PCs.

        PVSs are sold primarily to OEMs located in North America and Japan who
   integrate the vision systems into manufacturing equipment for the
   semiconductor and electronics industries. PVSs are also sold to system
   integrators located principally in North America, Japan, Europe, and
   Southeast Asia who integrate the vision systems into manufacturing equipment
   for the factory floor in industries ranging from automotive to
   pharmaceutical.

         "Point-and-Click" Programmable Systems

        The Checkpoint(R) family of vision systems (the Checkpoint 900 which
   runs on a PC and the Checkpoint 800 which plugs directly into a VME
   backplane) is designed for manufacturing engineers who do not program in
   C-language and are looking for a rapid application development environment.
   Checkpoint combines the Company's existing vision software and standard
   vision hardware platforms with a unique Microsoft Windows-based graphical
   user interface (GUI). Manufacturing engineers utilize pull-down menus and
   dialog boxes in the GUI to create customized vision applications. This
   "point-and-click" programming environment enables the developer to focus on
   tasks associated with solving the overall vision application, freeing the
   developer from the detail and complexity of programming in C-


                                       4
   6
   language. The library of vision tools currently available with Checkpoint
   enables users to solve a wide range of inspection, gauging, assembly
   verification, and defect detection problems.

        The Company introduced Checkpoint in 1994 for the factory floor market.
   Checkpoint is sold primarily to end users and system integrators located in
   North America, Japan, Europe, and Southeast Asia in a wide range of general
   manufacturing industries, such as manufacturers of medical devices,
   batteries, power tools, disposable consumer goods, and electronic components.
   Although the application environment is designed for engineers with little
   programming or machine vision experience, deployment of Checkpoint on the
   factory floor requires the services of trained system integrators to
   mechanically and electrically integrate Checkpoint into manufacturing lines.

        Application-Specific Modular Vision Systems

        Application-specific products are "packaged" combinations of software
   and hardware that are designed to solve targeted problems without any
   customization by the Company or its customers. The Company's
   application-specific products are designed to address particular requirements
   of certain vision applications and are sold to OEMs, system integrators, and
   end users worldwide. A partial list of application-specific products is as
   follows:

             Surface Mount Device Placement Guidance Package (SMD/PGP), when
       coupled with a Cognex 4000, 5000, or 8000 Series machine vision engine,
       quickly and accurately locates fiducial marks on printed circuit boards
       for alignment, inspects the quality of surface mount devices, and then
       guides the placement of those devices onto printed circuit boards. For
       high-performance lead inspection in time-critical applications, the
       SMD/PGP tools have real-time image acquisition capability, eliminating
       the need to stop the motion of the placement machine in order to capture
       an image of a moving part.

             Cognex acuReader/Optical Character Recognition (OCR) reads even the
       most degraded serial numbers from semiconductor wafers with near 100%
       accuracy.

             Cognex acuReader/2D reads automatic identification manufacturers
       (AIM) standard data matrix symbologies. The two-dimensional codes are
       used as alternative marks for identifying wafers, integrated circuit
       packages, liquid crystal display (LCD) panels, pharmaceutical packages,
       and for small parts tracking applications.

             Cognex acuReader/Optical Character Verification (OCV) verifies the
       print produced by laser, pad, or offset printing equipment.

             Cognex acuFinder(R) locates parts, regardless of rotation and
       scale, and guides robots in the assembly, sorting, and packaging of
       appliance, automotive, consumer, and electronics products.

             Ball Grid Array (BGA) Inspection Package inspects BGA devices for
       missing, misplaced, or improperly formed solder balls.

             Cognex Fiducial Finder, when coupled with a Cognex 4000, 5000, or
       8000 Series machine vision engine, locates fiducial or alignment marks on
       printed circuit boards.

             Cognex Print Quality Inspection (PQI), when coupled with a Cognex
       4000 or 5000 Series machine vision engine, quickly and accurately
       inspects print produced by laser, pad, or offset printing equipment.

        SURFACE INSPECTION SYSTEM PRODUCT LINE

        Fine-Line Intelligent Camera Systems

        Fine-Line Intelligent Camera Systems are complete surface inspection
   devices packaged in a compact and rugged enclosure. Each camera contains a
   line-scan charge-coupled device (CCD) sensor, image digitizer, digital signal
   processor (DSP), custom hardware for pixel processing, surface inspection
   algorithms in firmware, and a CPU for control and communications. In addition
   to the 


                                       5
   7
   camera, the Company provides a PC-based operator interface, specialized
   lighting components, and power supply/control boxes to provide customers with
   a complete solution to their surface inspection applications. Fine-Line
   systems can be used in a single-camera, "stand-alone" fashion for simple,
   narrow web applications, or they can be installed in multi-camera
   configurations to view wider webs. Fine-Line systems, which range in price
   from $25,000 to $150,000, depending upon the number of cameras, are targeted
   primarily at the plastics, non-wovens, and converting markets.

        iS High Performance Inspection Systems

        iS High Performance Inspection Systems are designed for the most
   demanding surface inspection applications. iS systems are built from a family
   of hardware and software components which include proprietary line-scan
   cameras with motorized camera mounts, specialized lighting systems,
   ultra-high performance image processing boards, Unix workstations, and
   intelligent defect detection and classification software algorithms. iS
   systems can contain from one to sixty cameras and can be used to inspect webs
   up to 25 feet wide at speeds of up to 5,000 feet per minute. iS systems,
   which range in price from $300,000 to $2,500,000, depending upon the number
   of cameras and the processing speed, are targeted primarily at metals,
   specialized coated paper, and high-value non-woven materials producers.

   RESEARCH, DEVELOPMENT AND ENGINEERING

        The Company engages in research, development and engineering (R,D & E)
   to enhance its existing products and to develop new products and
   functionality to meet market opportunities. The Company considers its
   on-going efforts in R,D & E to be a key component of its strategy.

        The MVS engineering group released the first product of the new 8000
   Series during 1997, with additional products of this series planned for
   release during 1998. The software for this series and the family of
   compatible hardware, from frame grabbers to fully embedded board-level
   vision systems, utilize the processing capabilities of Intel MMX
   architecture. During 1998, the MVS engineering group will be further
   leveraging the technical power of PatMax, a major advance in high-accuracy
   rotation and scale invariant pattern recognition, introduced by the Company
   in 1997. Both PatMax and PatMax/Inspect, an innovative companion defect
   inspection technology, will substantially increase the performance and range
   of the Company's application-specific products, such as surface mount device
   and wirebonder inspection, as well as increase the capabilities of the
   Company's "point-and-click" vision development systems, including Checkpoint.
   During 1998, the MVS engineering group also plans to release new versions of
   PatMax and PatMax/Inspect.

        The SIS engineering group introduced several new products during 1997,
   including products for improved illumination of large web applications,
   high-performance line-scan cameras and controllers, and an advanced
   intelligent classifier. These additional capabilities will improve both the
   performance and range of applications serving the metals industry, as well as
   broaden the number of applications and industries served to include plastics
   and non-wovens. The SIS Product Line was further expanded through the
   acquisition of Mayan Automation, Inc., a developer of intelligent
   camera-based machine vision systems for surface inspection, in the third
   quarter of 1997. The combination of intelligent camera systems for smaller
   applications and large, integrated systems technology provides the Company
   with the unique ability to match a wide range of user requirements. During
   1998, the SIS engineering group will further expand the capabilities of its
   newly-acquired intelligent camera technology to cost-effectively match higher
   performance requirements within the industries that it serves, while it also
   plans development activities in its integrated systems business to further
   improve performance. With the advent of as many as ten new intelligent
   classification systems (iLearn) coming on-line, the Company seeks to attain
   broad industry acceptance, as its customers find it easier to apply and
   benefit from surface inspection technology. iLearn automatically generates
   rules for classifying surface defects into user-defined categories, thereby
   dramatically reducing the start-up time and effort required to tune the

         In addition to internal research and development efforts, the Company
   intends to continue its strategy of gaining access to new technology through
   strategic relationships and acquisitions where appropriate.

        At December 31, 1997, the Company employed 152 professionals in R,D &
   E, most of whom are software developers. The Company's R,D & E expenses
   totaled $22,481,000, $19,434,000, and $13,190,000, or 14%, 16%, and 13% of
   revenue, in 1997, 1996, and 1995, respectively.

   MANUFACTURING

        The Company's MVS Product Line is manufactured at its Natick,
   Massachusetts headquarters. The Company's Natick manufacturing organization
   has completed its transition to a turnkey manufacturing operation whereby the
   majority of component procurement, subassembly, final assembly, and initial
   testing are performed under agreement by third-party contractors. After the
   completion of initial testing, the third-party contractors deliver the
   products to the Company to perform final testing and assembly. The products
   provided by the third-party contractors are manufactured using specified
   components and assembly and test documentation created and controlled by the
   Company. Certain components purchased by the third-party contractors are
   presently available from a single source.

        The Company's iS products are manufactured at its Alameda, California
   facility and its Fine-Line products are manufactured at its Montreal, Canada
   facility. The manufacturing processes at the Alameda and Montreal facilities
   consist of systems design, configuration management and control, component
   procurement, subassembly, integration and final test, quality control,
   shipment, and installation. Certain products are manufactured by third-party
   contractors using assembly and test documentation created and controlled by
   the Company. Certain components purchased by the third-party contractors are
   presently available from a single source.

   SALES AND SERVICE

        The Company markets its products through a direct sales force in North
   America, and through a direct sales force and distributors in Japan, Europe,
   and Southeast Asia. The Company's distributors do not have any rights of
   return, and payment for products is due upon delivery. Distributors generally
   have non-exclusive distribution rights and there may be more than one
   distributor per territory.

        The Company's direct sales force operates in the United States out of
   its Natick, Massachusetts headquarters, its Regional Technology Centers in
   Mountain View, California and Naperville, Illinois, and its sales offices
   throughout the United States; in Canada out of its Montreal, Quebec and
   Scarborough, Ontario offices; in Japan out of its Tokyo, Osaka, Nagoya, and
   Fukuoka offices; in Europe out of its France, Germany, England, Italy,
   Sweden, and Scotland offices; and in Southeast Asia out of its Singapore,
   Korea, and Taiwan offices.

        At December 31, 1997, the Company's direct sales and service force
   consisted of 134 professionals, including sales and application engineers.
   The majority of the Company's sales and service personnel have engineering or
   science degrees. Sales engineers call directly on targeted accounts and
   coordinate the activity of the application engineers. They focus on potential
   customers that represent possible volume purchases and long-term
   relationships. Opportunities that represent single-unit sales or turnkey
   system requirements are identified by the sales engineer and turned over to
   an independent system integrator or OEM that uses the Company's products. The
   Company sells its MVS products to customers that have entered or are expected
   to enter into volume discount contracts with the Company. These contracts are
   typically for one year and have associated delivery schedules.

        Sales to international customers represented approximately 62%, 55%, and
   59% of revenue in 1997, 1996, and 1995, respectively. One international
   customer based in Japan, Fuji America Corporation, accounted for
   approximately 18%, 11%, and 16% of revenue in 1997, 1996, and 1995,


                                       7

   respectively. Information about foreign and domestic operations, export
   sales, and significant geographic areas, as well as foreign currency and
   related risk may be found in the Notes to the Consolidated Financial
   Statements, appearing on pages 23 through 25 and 35 through 36 of the Annual
   Report to Stockholders for the year ended December 31, 1997, which is Exhibit
   13 hereto, and is incorporated herein by reference. Although international
   sales may from time to time be subject to federal technology export
   regulations, the Company to date has not suffered delays or prohibitions in
   sales to any of its foreign customers.

        The Company provides software update services and hardware maintenance
   on a contract basis. Software updates are provided via floppy disks and
   hardware maintenance is provided by repairing or exchanging printed circuit
   boards. Programming application services for projects can be contracted with
   the Company on a time-and-material basis only when doing so enhances the sale
   of the Company's standard products. Product courses are provided by the
   Company at its headquarters in Natick, Massachusetts, at its offices in
   Japan, France, Germany, and England, as well as at the customer site when
   required. These courses provide the user with both lecture and laboratory
   sessions covering the use of Cognex products.

   PATENTS AND LICENSES

        Since the Company relies on the technical expertise, creativity, and
   knowledge of its personnel, it utilizes patent, copyright, and trade secret
   protection to safeguard its competitive position. In addition, the Company
   makes use of non-disclosure agreements with customers, suppliers, employees,
   and consultants. The Company attempts to protect its intellectual property by
   restricting access to its proprietary information by a combination of
   technical and internal security measures. However, there can be no assurance
   that any of the above measures will be adequate to protect the proprietary
   technology of the Company. Effective patent, copyright, and trade secret
   protection may be unavailable in certain foreign countries.

        Cognex, Checkpoint, and acuFinder are registered trademarks of Cognex
   Corporation. Patmax, Fine-Line, iS, and iLearn are trademarks of Cognex
   Corporation. All other brand names, service marks and trademarks, whether or
   not registered, are the property of their respective owners.

        The Company's software products are generally licensed to customers
   pursuant to a license agreement that restricts the use of the products to the
   customer's purposes on a designated Cognex machine vision engine. The Company
   has made portions of the source code available to certain customers under
   very limited circumstances and for restricted uses. If source code is
   released to a customer, the customer is required by contract to maintain its
   confidentiality and, in general, to use the source code solely for internal
   purposes or for maintenance.

        Several users of the Company's products have received notice of patent
   infringement from Technivision Corporation and Jerome H. Lemelson alleging
   that their use of the Company's products infringes certain patents issued to
   Mr. Lemelson. Certain of these users have notified the Company that, in the
   event it is subsequently determined that their use of the Company's products
   infringes any of Mr. Lemelson's patents, they may seek indemnification from
   the Company for damages or expenses resulting from this matter.

        Two users of the Company's products were engaged in litigation with Mr.
   Lemelson/Technivision involving certain of these patents and the validity of
   these patents was placed in issue. One user entered into a settlement
   agreement with Mr. Lemelson. The Company is not a party to that settlement
   and has no indemnification claims, or related obligations, with respect to
   that settlement. Certain products sold by the Company, as well as the
   products of others, were identified in connection with this litigation, which
   claimed an allegedly infringing use.

        With respect to the second user, in April 1996 the U.S. District Court
   of Nevada ruled in favor of summary judgment for the user, thus disposing of
   all actions in favor of such user. In April 1997, the same U.S. District
   Court of Nevada reversed its decision with respect to the April 1996 summary


                                       8
   10
   judgment ruling. Subject to appeal of the reversal by the user, the case will
   proceed to trial. On October 1, 1997 Mr. Lemelson died; however the
   litigation will continue under his estate. The Company cannot predict the
   outcome of this litigation or any similar litigation which may arise in the
   future, or the effect of such litigation on the operating results of the
   Company. The Company does not believe its products infringe any valid and
   enforceable claims of Mr. Lemelson's patents.

   COMPETITION

        The Company competes with other vendors of machine vision systems, the
   internal engineering efforts of the Company's current or prospective
   customers, and the manufacturers of image processing systems. Any of these
   competitors may have greater financial and other resources than the Company.
   Although the Company considers itself to be one of the leading machine vision
   companies in the world, reliable estimates of the machine vision market and
   the number of competitors are almost non-existent, primarily because of
   definitional confusion and a tendency toward double-counting of sales. The
   primary competitive factors affecting the choice of a machine vision system
   include product functionality and performance (e.g. speed, accuracy, and
   reliability) under real-world operating conditions, flexibility,
   programmability, and the availability of application support from the vendor.
   More recently, ease-of-use has become a competitive factor and product price
   has become a more significant factor with respect to simpler guidance and
   gauging applications. The Company competes with the lower-cost, software-only
   solutions being introduced by various competitors on the basis of superior
   performance and price, rather than on price alone, through its 8000 Series.
   In the paper industry market for high-performance surface inspection systems,
   the Company has faced increased competition as a result of a merger between
   Honeywell, a former distributor of the Company's iS products, and Measurex, a
   supplier of competing surface inspection systems.

   BACKLOG

        At December 31, 1997, the Company's backlog totaled $32,618,000,
   compared to $25,347,000 at December 31, 1996. Backlog reflects purchase
   orders for products scheduled for shipment within six months. The level of
   backlog at any particular date is not necessarily indicative of future
   revenue of the Company. Delivery schedules may be extended and orders may be
   canceled at any time subject to certain cancellation penalties.

   EMPLOYEES

        At December 31, 1997, the Company employed 529 persons, including 206 in
   sales, marketing and support activities; 152 in research, development and
   engineering; 76 in manufacturing and quality assurance; and 95 in information
   technology, management, administration and finance. Of the Company's 529
   employees, 61 are located in Japan. None of the Company's employees are
   represented by a labor union and the Company has experienced no work
   stoppages. The Company believes that its employee relations are good.

   ITEM 2:  PROPERTIES

        In 1994, the Company purchased and renovated a 100,000 square-foot
   building located in Natick, Massachusetts. In 1997, the Company completed
   construction of a 50,000 square-foot addition to this building. The Company's
   corporate headquarters, principal administrative, sales and marketing,
   research, development and engineering, manufacturing and quality assurance,
   and support personnel are located in this facility. In addition, the Company
   leases facilities in the United States in California, Illinois, and Oregon,
   as well as in Canada, Japan, France, Germany, England, Italy, Sweden,
   Scotland, Singapore, Korea, and Taiwan.

        In 1995, the Company purchased an 83,000 square-foot office building
   adjacent to its corporate headquarters. The building is currently occupied
   with tenants who have lease agreements that expire at various dates through
   the year 2000, at which point, the Company plans to take occupancy of the
   building.

        In 1997, the Company purchased a three and one-half acre parcel of land
   situated on Vision Drive, adjacent to the Company's corporate headquarters in
   Natick, Massachusetts. This land is anticipated to be used for future
   expansion.

   ITEM 3:  LEGAL PROCEEDINGS

        To the Company's knowledge, there are no pending legal proceedings,
   other than as described in "Business - Patents and Licenses," which are
   material to the Company to which it is a party or to which any of its
   property is subject. From time to time, however, the Company may be subject
   to various claims and lawsuits by customers and competitors arising in the
   normal course of business, including suits charging patent infringement.

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

        There were no matters submitted during the fourth quarter of the year
   ended December 31, 1997 to a vote of security holders through solicitation of
   proxies or otherwise.

                        REPORT OF INDEPENDENT ACCOUNTANTS
                       ON THE FINANCIAL STATEMENT SCHEDULE


To the Board of Directors and Stockholders of Cognex Corporation:

        Our report on the consolidated financial statements of Cognex
Corporation has been incorporated by reference in this Form 10-K from page 40 of
the 1997 Annual Report to Stockholders of Cognex Corporation. In connection with
our audits of such financial statements, we have also audited the related
financial statement schedule for each of the three years in the period ended
December 31, 1997 listed in Item 14(a) of this Form 10-K.

        In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information required to be
included therein.
