   ITEM 1.  BUSINESS


   CORPORATE PROFILE


      Cognex 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, healthcare, metals, and paper industries 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:




     QUESTION              DESCRIPTION                            EXAMPLE
     --------              -----------                            -------
                                                            
     GUIDANCE

     Where is it?          Determining the exact physical         Determining the position of a printed circuit board
                           location of an object.                 so that a robot can automatically be guided to insert
                                                                  electrical components.

     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 pharmaceutical
                           defects.                               labels and packaging.

     GAUGING

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


                                       1
   4
      Once the machine vision system has processed the image and made 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 that moves the
   part, or alternatively, to a computer file for analysis or subsequent process
   control. This process is repeated for each part on the line, or continuously
   for process material, as it 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
   progammable systems to application-specific solutions tailored to solve
   particular manufacturing tasks.

      End users are companies that manufacture products, such as radios, phones,
   and ball-point pens, on the factory floor. While they may purchase capital
   equipment containing machine vision or contract 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. The Company's
   current products are designed for factory automation because the Company
   believes that this market currently 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.

      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 comes 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 many times
   larger than 

                                       2
   5
   the OEM segment. Consequently, the Company has invested heavily 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. Approximately 55% of the Company's revenue comes
   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
   expects to continue to invest in the expansion of direct sales, support,
   local marketing, and local engineering in all of these regions.

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


   PRODUCTS


      The Company develops and sells a wide range of standard machine vision
   products - proprietary vision software together with vision hardware (vision
   engines) - which require minimal customization and support by the Company.
   The machine 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. Customers select
   the tools necessary to solve their vision problem from the Company's vision
   software library and configure their solution by either writing a C-language
   program or utilizing a graphical user interface (GUI). 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. All of the Company's current products are on-line
   systems that run at production speeds and locate images in a two-dimensional
   scene. A typical Cognex machine vision system, including software and
   hardware, ranges from $7,500 to $20,000; however, the Company's Web
   Inspection Systems range from $250,000 to $2,000,000. The Company estimates
   that it had sold an aggregate of approximately 52,000 machine vision systems 
   as of December 31, 1996.

      GENERAL-PURPOSE MACHINE VISION SYSTEMS

      Programmable Vision Engines

      Cognex Programmable Vision Engines (PVEs) are board-level vision systems
   programmable in C-language. PVEs 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 vision computers,
   each of which contains an on-board central processing unit (CPU) and
   co-processor, image capture mechanism, memory, and input/output connector,
   enabling the host computer to off-load all vision tasks to the vision
   processor. 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
   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,

                                       3
   6
   allowing customers to readily upgrade to higher performance systems or to
   change platforms as application needs change.

      The Company currently offers the Cognex 4000 Series, which plugs directly
   into a VME backplane, and the Cognex 5000 Series, which is for personal
   computers (PCs). PVEs are sold primarily to OEMs located in the United States
   and Japan who integrate the vision engines into manufacturing equipment for
   the semiconductor and electronics industries. PVEs are also sold to system
   integrators located principally in North America, Japan, Europe, and
   Southeast Asia, who integrate the vision engines into manufacturing equipment
   for the factory floor in industries ranging from automotive to
   pharmaceutical.

      During 1996, the Company offered the VisionPro product line to satisfy
   an increasing demand for lower-cost, software-only solutions. The Company has
   added increased functionality to the product and has recently focused its
   selling and marketing efforts toward OEMs and system integrators who require
   lower-cost machine vision systems to run simpler applications.

       "Point and Click" Programmable Systems

      The Checkpoint family of vision systems (the Checkpoint 600 for the 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 who 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 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-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 MACHINE 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 list of application-specific products is as follows:

      Web Inspection Systems perform high-speed surface inspection on a variety
   of materials manufactured on continuous sheets or "webs." These systems are
   more hardware intensive than other Cognex products and include lighting,
   custom line-scan cameras, and a multi-board vision processing system along
   with the operator workstation. Each system is individually configured by the
   Company's Isys subsidiary to satisfy the customer's specific requirements.

      Surface Mount Device Placement Guidance Package (SMD/PGP), when coupled
   with a Cognex 4000 or 5000 Series machine vision engine, quickly and
   accurately locates fiducial marks on printed circuit boards for alignment,
   inspects the quality of SMD devices, and then guides 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.

                                       4
   7
      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 (IC) 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 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 or 5000 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.


   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. Three new
   technologies currently being developed by the Company include: (1) PatMax, a
   new method for high accuracy, rotation and scale invariant pattern
   recognition and defect detection, which is anticipated to be introduced in
   the second half of 1997, (2) a digital 3D sensor, which is anticipated to be
   ready for market in 1998, and (3) the Cognex 8000 Series, the next-generation
   vision engine, which is anticipated to be introduced in the second half of
   1997. The Company has begun to file patents on new technologies it has
   developed for PatMax and the digital 3D sensor. 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.

      The R, D & E organization consists of software engineering, hardware
   engineering, and research and development. Software engineering is
   responsible for the development of the Company's core image processing and
   image analysis tools, as well as the maintenance, quality assurance, and
   documentation of software products. Dedicated teams within the software group
   are responsible for the development of the VisionPro and Checkpoint product
   lines, and the SMD/PGP tools, along with the development of application
   products used in wire bonders and other custom applications. Hardware
   engineering is responsible for the development of hardware products,
   primarily vision engines and vision chips. The research and development group
   focuses its energies on enhanced vision technology capabilities. The
   Company's Acumen development center is responsible for the development of
   application-specific products for the semiconductor industry, while the
   development of Web Inspection Systems is performed by the Isys engineering
   organization.

      At December 31, 1996, the Company employed 132 professionals in R, D & E,
   most of whom are software developers. The Company's R, D & E expenses totaled
   $19,434,000, $13,190,000, and $9,933,000 in 1996, 1995, and 1994,
   respectively.


   MANUFACTURING


      With the exception of its Web Inspection Systems, the Company's
   manufacturing organization is located at its Natick, Massachusetts
   headquarters. During 1996, the Company substantially 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 a single third-party 

                                       5
   8
   contractor. After the completion of initial testing, the third party
   contractor delivers the products to the Company to perform final testing and
   assembly. The products provided by the third party contractor are
   manufactured using specified components and assembly and test documentation
   created and controlled by the Company. Certain components purchased by the
   third party contractor are presently available from a single source.

      The Company's Web Inspection Systems are manufactured in Alameda,
   California. The manufacturing process consists 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, Japan, and Europe, and through a direct sales force and distributors
   in 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 North America 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 Japan out of its Tokyo and Osaka offices; in
   Europe out of its offices in France, Germany, England, and Italy; and
   in Southeast Asia out of its Singapore and Korea offices.

      At December 31, 1996, the Company's direct sales and service force
   consisted of 91 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.

      Sales to international customers represented approximately 55%, 59%, and
   62% of revenue in 1996, 1995, and 1994, respectively. One international
   customer based in Japan, Fuji America Corporation, accounted for
   approximately 11%, 16%, and 20% of revenue in 1996, 1995, and 1994,
   respectively. Segment information, including information about foreign and
   domestic operations, export sales, and significant geographic areas, may
   be found in the Notes to the Consolidated Financial Statements, appearing on
   pages 26 and 27 of the Annual Report to Stockholders for the year ended
   December 31, 1996, 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 sells its 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.

      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.

      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. Effective patent, copyright, and trade secret
   protection may be unavailable in certain foreign countries.

      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, while the second user had the allegations
   dismissed by the court. Although the Company was not named in this
   litigation, it entered into a joint defense agreement with one party named
   therein, who subsequently entered into a settlement agreement with Mr.
   Lemelson for reasons unknown to the Company. 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.

      In June 1995, a Magistrate Judge filed a recommendation that summary
   judgment be entered in favor of the Company's other user that was engaged in
   the aforementioned litigation with Mr. Lemelson/Technivision. This
   recommendation, which was accepted by the U.S. District Court of Nevada in
   April 1996, disposed of all the actions in favor of the user in this case.
   The Company, however, cannot predict the outcome of 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 

                                       7
   10
   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 VisionPro product line.


   BACKLOG


      At December 31, 1996, the Company's backlog totaled $26,835,000, compared
   to $27,655,000 at December 31, 1995. 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 the future operating
   performance 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, 1996, the Company employed 404 persons, including 148 in
   sales, marketing and support activities; 132 in research, development and
   engineering; 54 in manufacturing and quality assurance; and 70 in management,
   administration and finance. Of the Company's 404 employees, 43 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. 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 Japan, France, Germany, England, Italy, Singapore, and Korea.

      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 1995, the Company began work on a 50,000 square-foot expansion of its
   corporate headquarters, which was completed during the first quarter of 1997.
   However, since the Company's planned hiring over the next several quarters is
   substantially less than anticipated when construction commenced, occupancy of
   this additional space, along with the related operating costs, will be
   delayed until the additional space is needed, which is anticipated to be late
   1997 or early 1998.

   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.

                       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 29 of the 1996
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,
1996 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.
