products and to access, share and manage their product data collaboratively. The
Company's support services include implementation, consulting and training
services designed to assist customers in reengineering their product development
processes and in increasing productivity.
 
     The Company was organized under the laws of the State of Delaware on June
9, 1972 as Prime Computer, Inc. The Company's principal executive offices are
located at 100 Crosby Drive, Bedford, MA 01730 and its telephone number is (617)
275-1800.
 
RECENT DEVELOPMENTS
 
     On November 1, 1996, Kathleen A. Cote, President and Chief Operating
Officer of the Company, was appointed Chief Executive Officer of the Company.
Ms. Cote, who was named a Director of the Company on July 25, 1996, has been
with the Company since November 1986, serving in various positions, including
Vice President, Services and Vice President, Manufacturing.
 
     On March 19, 1997, the Company announced the termination of its agreement
with J.F. Lehman & Company for the sale of its Open Service Solutions ("OSS")
business unit and the signing of a non-binding letter of intent with M.D. Sass
Investors Services, Inc. ("Sass"), a 17% shareholder of the Company, for the
purchase by Sass of a 51% interest in the OSS business. In connection with this
transaction, the Company will receive from Sass $5.1 million in cash and will
receive from the entity that operates the OSS business (a) $25 million in cash
and (b) a promissory note in the amount of $25 million. The cash payment of $25
million will be funded by a bank loan to the OSS business, secured by its
assets. The Company will continue to own 49% of the OSS business, subject to an
option granted to Sass to purchase up to one-fifth of the balance of the
Company's equity position. The transaction is subject to execution and delivery
of a definitive agreement and to the availability of financing, receipt of
approval from the Company's banks, compliance with the Company's financing
instruments and other customary closing conditions. As a result, no assurance
can be given that the transaction will be consummated.
 
OVERVIEW
 
     The traditional computer-aided design, computer-aided manufacturing
("CAD/CAM") product development process has focused primarily on the design of
individual components or parts and optimization of the individual engineer's
productivity. Generally, this process is implemented through assembly of the
individually-designed components and physical mock-ups.
 
     To improve the design process, reduce development time and costs and
improve quality, many manufacturers are moving beyond the traditional product
development process to a process that focuses on complete assemblies,
substitutes electronic prototypes for physical prototypes and enables design and
build teams to work concurrently. This product development process, which is
marketed by the Company as "Electronic Product Definition" ("EPD"), is
"assembly-centric", while traditional product development is
"component-centric." EPD is the Company's product and process response to the
customer's need to concurrently create, manage, share and reuse electronic
product information in a collaborative environment. Companies from the
aerospace, automotive, white goods, shipbuilding and consumer products
industries today implement EPD in an effort to obtain a competitive advantage.
 
     EPD enables customers to create and store a single product definition that
can be made available in electronic form for further design work, simulation and
analysis, manufacturing planning, production

engineering, and other related activities in the product development process.
Using the EPD approach, individuals from various disciplines of a customer's
extended enterprise and key suppliers can collaborate more effectively and can
concurrently access and manipulate design and manufacturing information early in
the development process where the greatest cost, quality, and productivity gains
can be achieved.
 
     Today, collaborative design environments are more often heterogeneous as
manufacturers and their suppliers employ different CAD/CAM systems. The Company
has developed its EPD approach to allow EPD to be implemented by users of
product information created using the Company's or another CAD/CAM system.
 
     The Company markets two families of software products which may be used
separately. When integrated and complemented by the Company's implementation and
support services, these products provide customers with a comprehensive EPD
capability.
 
     Design Automation Software -- which includes component modeling software
used to design, test, and manufacture individual components; and assembly
modeling software used by design teams to work concurrently to design and
assemble components digitally into complete products; and
 
     Product Data Management ("PDM") Software -- which is used to access, share,
view, configure and manage product data, including geometry and associated
product attributes, by cross-functional product teams in a collaborative manner
throughout the enterprise.
 
SOFTWARE PRODUCTS
 
     The Company's products include primarily software for design automation and
PDM. Although these products may be applied separately, the Company believes
that its customers achieve the greatest benefits from these products by applying
them in an integrated fashion to form an EPD environment.
 
     The Company's design automation software includes products that allow a
customer to create and store a single product definition that can be made
available in electronic form for simultaneous review and analysis by design and
build teams located throughout the customer's enterprise. These teams can use
the software for further design work, simulation and analysis, manufacturing
planning, production engineering, and other activities in the product
development process.
 
     The Company's PDM products provide data access needed to realize the
benefits of forming collaborative, concurrent design teams. These products
include software for product data management, configuration management, product
visualization, product structure navigation and workflow planning and
management.
 
     DESIGN AUTOMATION SOFTWARE
 
     Component Modeling Software.  The Company's CADDS family of component
modeling products provides integrated CAD/CAM solutions from conceptual design
to manufacturing. The principal strength of the Company's CADDS products is its
hybrid modeler, which allows designers to choose the appropriate design
technique (wireframe, surface or solids) and the appropriate modeling approach
(parametric or explicit) that is best suited for the design problem. Hybrid
modeling software facilitates the use of "legacy" data (which contributes to the
faster design of derivative products), and enhances sharing of CAD data with
extended enterprise suppliers and contractors. Hybrid modeling also enables
engineers to model complex parts and contributes to lowering part counts, rapid
prototyping and facilitating transfer of design data into the manufacturing
process.
 
     CADDS products also include integrated software development tools for
detail design, drafting and analysis and CAM packages for a variety of numerical
control and other manufacturing applications (e.g. five-axis numerical control).
 
     CADDS 5, the Company's current version of CADDS, incorporates feature-based
parametric and explicit solids modeling, variational geometry and sketching,
NURBS-based surface modeling and an easy-to-use, icon-driven user interface.
CADDS 5 operates on workstations marketed by Digital Equipment, Hewlett-Packard,
IBM, Silicon Graphics and Sun Microsystems.
 
                                        2
<PAGE>   4
 
     Assembly Modeling Software.  The Company's Concurrent Assembly Mock-Up
("CAMU") software provides a multi-user, concurrent environment to enable
cross-functional teams to design and build products within the context of the
entire product assembly as compared to isolated component design. CAMU software
is designed to manage complex assemblies involving thousands of parts, and to
enable each member of a design and build team to see simultaneously the work of
others as well as the entire product structure. Users are able to design complex
product structures easily, readily change one part, reflect the changes in other
parts, and check the fit and configuration of individual design changes with the
product as a whole.
 
     PELORUS Products.  The Company continues to develop its Pelorus products to
provide a suite of design automotive applications built for the PC/Windows
platforms. Its Pelorus products are organized around principles of
assembly-concentricity, interoperability and associativity/flexibility.
 
     Other Software.  In addition, the Company markets a range of other software
products for DOS and UNIX operating systems, including its MEDUSA 2D integrated
drawing-based design environment and products, its Personal Designer and
Personal Machinist Series, and its Dimension III products for plant design and
plant maintenance.
 
     PRODUCT DATA MANAGEMENT SOFTWARE
 
     The Company's PDM products and software solutions are designed to improve
collaboration and information access and sharing throughout an enterprise. These
products provide for data management, configuration management, workflow
management, advanced product visualization and product structure navigation.
Using these products and software solutions, design and build teams have the
ability to leverage and control all information about product development and
related design, test, analysis and manufacturing processes. The integration of
the Company's PDM with design automation software products from the Company or
other design automation suppliers allows customers to implement a product
development process organized around a single common electronic definition of
the product. The Company's PDM products operate on Windows/NT and most major
UNIX platforms and support Oracle's industry-standard relational database
management software.
 
     The Company's principal data management software is its Optegra family of
object-oriented PDM software. Optegra employs object-oriented technology in a
client/server architecture and provides the capabilities to develop customized
templates for specific product development tasks such as management of
engineering change orders; to integrate data from multiple applications; and to
support concurrent enterprise-wide management of product data across an extended
enterprise.
 
     Data Management Software.  The Company's data management software products
provide single and distributed vaulting of product geometry and attribute data
("Optegra Vault" and "Optegra Distributed Vault"), control of access to such
data by clients and project organization support for engineering and related
applications. Vaulting is the electronic control of data stored in a secured
central depository. This software works with a variety of geometry systems,
including AutoCAD, IBM CATIA and Pro/ENGINEER, as well as the Company's CADDS
and MEDUSA applications.
 
     Configuration Management Software.  The Company's configuration management
software applications ("Optegra Configuration Master") simplify configuration
management by allowing manufacturers to manage and maintain a total product
configuration from a single database for its entire life cycle. The software
integrates engineering and manufacturing bills of material into one computerized
record of configuration and provides a means to track the history of each item.
 
     Workflow Management Software.  The Company's workflow management software
("Optegra Workflow Manager") permits organizations to distribute product-related
data in accordance with routing instructions. These instructions can be
predetermined or on an ad hoc basis.
 
     Other EPD Software.  On March 5, 1997, the Company announced a new software
tool, EPD.Connect, that is designed to provide a virtual work environment for
product manufacturers that improves team productivity by connecting members of a
design team with the information and applications specifically required for
their individual tasks. EPD.Connect software dynamically links a product to its
structure and
 
                                        3
<PAGE>   5
 
associates it to the processes and applications used to create or modify the
product. A user is able to review at one time a graphical representation of the
product and its structure and any of the processes used in the design and
modification of the product, and to share the information with other members of
the design team. The Company anticipates its EPD. Connect software will be
shipped at the end of March 1997.
 
SOFTWARE SUPPORT SERVICES
 
     The Company's software support service offerings are developed to enhance
the productivity of its customers' people, processes and technology. Because of
the complexity of its customers' requirements, the Company markets a wide range
of services and ongoing support. The Company's service offerings include
assessment and design, installation and integration, customization, project
management, functional utilization of the Company's products and ongoing system
support.
 
     Software Services.  The Company provides software support services,
including bug fixes, enhancements and hotline support, through a global network
of service centers. This support network allows the Company to leverage
information and resources across diverse geographic areas to respond efficiently
to critical customer issues.
 
     Productivity Services.  The Company's productivity services include
business consulting, implementation consulting for EPD, design automation and
PDM products, and customer education and training.
 
     Business consulting is an integral part of the Company's EPD strategy and
includes the application of the Company's Product Development Diagnostic
consulting approach and its best practices database to re-engineering of the
Company's customers' design processes. The Product Development Diagnostic
approach assesses the effectiveness of people, processes and technology in a
customer's product development process, compares that with known industry best
practices and highlights opportunities for improvement.
 
     Implementation consulting services may include technology integration,
optimization and project management. Implementation consulting may also include
specialized software development to integrate the Company's software products to
the particular needs of the customer's product development process.
 
OPEN SERVICE SOLUTIONS
 
     The Company's Open Service Solutions (OSS) business provides services to
both the Company's software customers and to customers of selected third party
hardware and software vendors. The OSS offerings include system hardware and
operating systems services, network design and implementation, systems
integration, and database support and consulting for enterprise-wide systems and
networks. Open Service Solutions is a worldwide support organization that is ISO
9000 certified.
 
     On March 19, 1997 the Company signed a non-binding letter of intent with
M.D. Sass Investors Services, Inc. ("Sass"), a 17% shareholder of the Company,
for the purchase by Sass of a 51% interest in the OSS business. (See "Recent
Developments" above).
 
PRODUCT DEVELOPMENT
 
     The Company's software developers seek to understand customer requirements
and rapidly and cost effectively build and deliver high quality products and
enhancements that respond to those requirements. Its developers are organized
into concurrent design and build teams, each of which has a focus on specific
software development projects or basic technologies. The Company employs
advanced software development tools widely. The Company has three principal
development centers, located in Bedford, Massachusetts, San Diego, California
and Pune, India.
 
     During 1994, 1995 and 1996, the Company spent approximately $58.8 million,
$41.5 million and $40.1 million (including amounts capitalized as software
development), respectively, on software research, development and engineering,
constituting approximately 20%, 15% and 13% of its total software revenue.
 
                                        4
<PAGE>   6
 
SALES, MARKETING AND DISTRIBUTION
 
     The Company's customers are principally automotive, aerospace,
shipbuilding, general mechanical and consumer goods manufacturers, for whom
rapid and cost effective product development is critical. These customers build
products having complex assemblies employing an extended enterprise of
geographically dispersed developers and manufacturers.
 
     Sales to these customers are complex and usually involve providing
diagnostic consulting and support for customer implementation of the Company's
software products in an EPD process. These customers typically purchase not only
software for component modeling, assembly design and product data management,
but also diagnostics, implementation consulting and training.
 
     The Company has developed a specialized sales and support organization,
which it refers to as its Global Industries Group, with knowledge of
industry-specific development processes and the skills to advise and support the
customer with respect to implementation of EPD.
 
     A key component of the Company's sales strategy is to target industry
leaders for each of the Company's principal markets. Among its principal
customers which are implementing the Company's EPD strategy are Lucas Aerospace
Ltd., Halliburton Energy Services, Lockheed Martin Corporation, The Raytheon
Company, BMW Rolls-Royce, Short Brothers, The Rover Group, Hughes Space and
Communications Company, Vickers Shipbuilding and Engineering Ltd., Fiat Auto
S.p.A., Peugeot S.A., Rolls-Royce Aerospace Group, Allison Engine Corporation
and the four principal partners of Airbus Industrie -- Aerospatiale S.N.I.,
British Aerospace Airbus Limited, Construcciones Aeronauticas, S.A. and
Daimler-Benz Aerospace Airbus GmbH.
 
     The Company markets its products and services through a worldwide direct
sales force located in the United States, Europe, Australia and Asia. In those
countries in which the Company does not have a direct sales force, the Company
distributes its products through international distributors.
 
     To complement the Company's worldwide direct sales organization, the
Company has established alternate channels of distribution, including
value-added resellers and systems integrators.
 
     While no one customer accounted for more than ten percent of the Company's
total revenue in 1996, the Company derived approximately 16% of its 1996
software product revenue from a contract with Electronic Data Systems, as a
systems integrator to the Rolls Royce Aerospace Group and Allison Engine
Corporation, and approximately 6% of its 1996 software product revenue related
to a contract with Peugot S.A. including Automobile Peugeot and Citroen.
 
INTERNATIONAL OPERATIONS
 
     During 1994, 1995, and 1996, international sales, including U.S. export
sales, accounted for approximately 69%, 73% and 73% of total revenue,
respectively. Financial information concerning domestic and international
operations and the Company's foreign currency hedging program appear in Note 8
and Note 2, respectively, of Notes to Consolidated Financial Statements.
 
     While computer technology and software have evolved toward universal
standards, there continue to be differences in languages, applications and
software usage among countries which are best recognized by local management.
Country managers work closely with the heads of each of the Company's business
units to tailor product development and marketing strategies to the needs of
each foreign market. The Company has a significant presence in each of the major
markets for its products, including North America, Germany, the United Kingdom,
France, Italy and Japan. In addition, the Company also markets its products in
Eastern Europe and the People's Republic of China.
 
PRODUCTION
 
     The Company designs, develops and produces the majority of its software
products and makes its products, user manuals and other documentation available
on a variety of electronic and printed media. Shipments are generally made
within one to two weeks of receiving an order which is common in the software
industry. In light of the short time between order and shipment of the Company's
products, the Company
 
                                        5
<PAGE>   7
 
generally has relatively little backlog at any given date, and the Company does
not believe that backlog is representative of potential sales for any future
period.
 
     The Company has from time to time licensed from third parties certain
technology for inclusion in its products and expects that it will continue to do
so in the future. These licenses generally provide for the Company's payment of
royalties based on product sales. During 1995 and 1996, the Company expensed
approximately $12.6 million and $16.1 million, respectively, for royalties and
support fees to third parties.
 
COMPETITION
 
     The software markets in which the Company operates are highly competitive
and characterized by rapid advances in technology. To compete successfully, the
Company must continue to enhance its current products and services and develop
new products and services which can be offered at competitive prices and on a
timely basis.
 
     The Company considers its principal competitors in the EPD market to be IBM
(which markets a component modeling system, CATIA, developed and maintained by
Dassault Systems S.A.) and Unigraphics, a division of Electronic Data Systems.
In the design automation market, the Company's principal competitors are
Intergraph Corporation, Parametric Technology Corporation and Structural
Dynamics Research Corporation. In the product data management market, the
Company competes with a number of smaller companies, including Metaphase
Technology, Inc. and Sherpa Corporation. In the area of design automation for
complex assemblies, one of the Company's most significant sources of competition
also comes from design tools developed internally by manufacturers to meet their
own needs.
 
     The Company believes that the principal competitive factors in its markets
are its ability to provide EPD products and services, product quality and
functionality, product breadth and integration, support, ease of product use,
sales and marketing strength, customer support services, corporate reputation
and financial strength.
 
     Because of the intense competition and rapid technological changes in the
industry, the Company's business will be adversely affected if the Company
incurs significant delays in developing new products or enhancements, if such
products or enhancements do not gain customer acceptance, or if products or
technologies developed by others serve to render the Company's products or
technologies noncompetitive or obsolete. The Company is aware of ongoing efforts
by competitors to develop competitive products, and there can be no assurance
that competitors will not develop equivalent or superior products to those
produced by the Company. The Company's competitive position is also affected by
the financial strength of its competitors. Many of the Company's current and
potential competitors have greater financial and operating resources than the
Company and the Company has a higher debt-to-equity ratio and a higher cash debt
service than most of its competitors, and a negative net worth.
 
     The Company's services business competes on the basis of price and the
quality and reliability of its customer services, support, consulting and
training. As the Company continues to expand its services beyond its installed
customer base to products sold by other vendors and to networks and systems
integration services, the Company believes that competition will increase for
non-proprietary products.
 
PROPRIETARY RIGHTS
 
     The Company relies on a combination of contracts, patents, copyrights and
trade secrets to establish and protect its proprietary rights in technology. In
addition, the Company maintains relevant trademark registration in its major
markets. The Company distributes its products under software license agreements
which grant customers licenses to the Company's products and which contain
various provisions protecting the Company's ownership and confidentiality of the
licensed technology. The source code of the Company's products is protected as a
trade secret and as an unpublished copyrighted work. However, no assurance can
be given that others will not copy or otherwise obtain and use the Company's
products or technology without authorization. In addition, effective copyright
and trade secret protection may be unavailable or limited in certain foreign
countries.
 
                                        6
<PAGE>   8
 
     The Company believes that, due to the rapid technological advances within
its industry, factors such as the technological and creative skills of its
personnel are more important to establishing and maintaining a technology
leadership position within the industry than are the various legal protections
of its technology.
 
     From time to time, the Company is subject to claims of infringement by it
of proprietary rights of third parties. There can be no assurance that such
claims, if resolved in a manner unfavorable to the Company, will not have a
material adverse effect on the Company.
 
EMPLOYEES
 
     As of December 31, 1996, the Company had a total of approximately 2,000
employees. The Company has not experienced any work stoppages, and it considers
its employee relations to be satisfactory.
 
EXECUTIVE OFFICERS
 
     The following persons are executive officers of the Company as of December
31, 1996, having been appointed to their respective positions to serve until the

(1) These facilities have excess or vacant space which the Company is attempting
    to sublease.
 
     The Company also leases additional space in various locations throughout
the United States and abroad, primarily for sales, customer service and R&D
operations. The Company believes that its existing facilities are adequate to
meet its current requirements. Approximately 62.5% of the space in the
facilities listed in the foregoing table is currently used by the Company in its
operations.
 
     The Company has approximately 203,600 square feet of vacant leased
facilities that it is currently attempting to sublease. It is also subleasing
approximately 764,600 square feet at a loss. A substantial portion of these
sublet facilities are located in the Northeastern region of the United States
and in the United Kingdom. The Company is continuing its efforts to sublease all
its vacant facilities.
 
     If the Company is unsuccessful in its efforts to negotiate additional
subleases or extend existing subleases on these facilities, the future cash
needs to meet these facility obligations will be substantial, including
approximately $11 million in 1997, $12 million in 1998, and $12 million in 1999,
net of known sublease receipts and assuming there are no lump-sum settlements on
any of the leases. Based upon current and expected real estate conditions, the
Company has reserved approximately $61.5 million in connection with its vacant
facility obligations for financial reporting purposes as of December 31, 1996,
which it believes is adequate. (See Note 6, "Capital Leases, Lease Commitments
and Rent Expense" of Notes to Consolidated Financial Statements.)
 
ITEM 3.  LEGAL PROCEEDINGS
 
     (1) On March 28, 1991, Joseph and Josephine Dieter, former stockholders of
the Company, brought suit against the Company, DR Holdings, DR Acquisition
Corporation, a former subsidiary of DR Holdings, Mr. Russell E. Planitzer,
Chairman of the Board of Directors of the Company, and Messrs. Don E. Ackerman
and Peter M. Castleman, former directors of the Company, in the Court of
Chancery of Delaware as both an individual and a class action (on behalf of all
persons, other than the defendants, who were stockholders of the Company on
December 28, 1989). The suit arises out of the merger between the Company and
certain subsidiaries of DR Holdings, and the related merger agreement. The suit
alleges, among other things, that, in connection with the acquisition of the
Company by DR Holdings, the Board of Directors of the Company breached its
fiduciary duties to Company stockholders by (i) approving the merger which
plaintiffs allege was unfair to Company stockholders, and (ii) by not
withdrawing from the merger agreement and/or renegotiating the consideration
that was to be received by Company stockholders whose shares were not purchased
in the tender offer. The plaintiffs seek, among other things, an order granting
all Company stockholders as of
 
                                        8
<PAGE>   10
 
December 28, 1989 damages in an undetermined amount. The plaintiffs then filed
an amended and supplemented complaint which removed DR Holdings as a defendant
since it is in bankruptcy, and removed DR Acquisition Corporation since it had
been merged into the Company. The trial occurred in September of 1996. The
Company is in the process of filing post trial briefs and the Court is expected
to have the matter under submission by July, 1997. Although the parties have
engaged in post-trial settlement discussions, it is not yet possible to predict
the outcome or quantify any possible exposure of the Company. If this lawsuit is
not settled, and the court awards the plaintiffs substantial monetary damages,
it could have a material adverse effect on the Company's financial condition and
results of operations.
 
     (2) In a letter dated June 11, 1993, the United States Environmental
Protection Agency ("EPA") notified the Company of its potential liability
pursuant to the Comprehensive Environmental Response Compensation and Liability
Act ("CERCLA") for a release of hazardous substances disposed of at the Shaffer
Landfill portion of the Ironhorse Park Superfund Site in Billerica,
Massachusetts ("Shaffer Site"). The Company was one of approximately 60
businesses and individuals to receive such a letter. The Company is cooperating
with approximately 30 other potentially responsible parties ("PRPs") who have
formed a group, and expects to participate in the common efforts of that group.
The Company has informed the EPA of its intent to cooperate with the other PRPs
in common efforts. The Company investigated the extent of its involvement with
the Shaffer Site and participated in a confidential mediation process which
allocated remedial costs among the members of the PRP group. The Company has
received information through the PRP group indicating that the anticipated costs
of completing the EPA's proposed remedy at the Shaffer Site is likely to range
between $20 million and $30 million. After the PRPs failed to reach agreement
with the EPA regarding settlement, the Department of Justice ("DOJ") and the
Massachusetts Attorney General ("MAG") both filed complaints on January 5, 1995,
seeking past costs against 10 PRPs. The Company was not named. However, it could
be named later by the government, and some of the named defendants have
indicated they will commence third-party actions against other PRPs, including
the Company, if ongoing negotiations do not result in a settlement. Negotiations
have been ongoing relative to several substantive matters and the Company cannot
predict at this time if any agreement on issues will be reached with the
government.
 
     (3) Several tax issues which pertain to Computervision tax returns for
years prior to 1988 (when Computervision was acquired by Prime Computer, Inc.)
remain outstanding. The most significant issue involves the qualification of a
domestic international sales corporation ("DISC") for tax years 1983 and 1984.
If the DISC is disqualified, the Company will be subject to additional tax and
interest in the range of $9.0 million to $12.0 million after the usage of net
operating losses. A trial on these issues was held before the Tax Court on
October 25, 1994. On March 18, 1996 the Tax Court ruled in favor of the Company.
On April 16, 1996 the Company filed a Motion for Reconsideration with the Tax
Court on the one issue, which concerned whether income was reportable as capital
gain or ordinary income, on which the decision was unfavorable to the Company.
The Motion for Reconsideration was denied by the Judge on May 27, 1996. As to
the portion of the decision unfavorable to the government, the Company does not
know whether the government will appeal the decision. Even if the government
does not appeal the decision, the Company will owe some tax and interest on this
case, but is also owed a refund on a related case. The computation of the tax
payment and the timing of the tax payment and refund have not been determined.
The Company's calculation of the adjustments resulting from the Court's decision
were reviewed by Counsel and submitted to the IRS on November 12, 1996.
 
     (4) The Company is involved in numerous other legal proceedings and
litigation incidental to the normal course of the Company's business. The
Company believes that the ultimate disposition of these other proceedings and
litigation will not have a material adverse effect on the Company's financial
position.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matters were submitted to the vote of the security holders of the
Company during the fourth quarter of the fiscal year ended December 31, 1996.

     The Company's Revolving Credit Agreement prohibits the Company from paying
cash dividends. The Company is also restricted from paying cash dividends under
the terms of the Indenture for its 11 3/8% Senior Subordinated Notes due 1999.
Although a prior bank credit agreement permitted limited dividends, on October
21, 1993, the Board of Directors of the Company voted to discontinue paying
dividends.
 
     As of March 25, 1997, there were 63,575,158 shares of the Company's common

ITEM 6.  SELECTED FINANCIAL DATA
 
     The response to this item is contained in Note 14, "Selected Financial
Data" of the Notes to the Consolidated Financial Statements.
 
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     This Management's Discussion and Analysis of Financial Condition and
Results of Operations should be read in conjunction with the consolidated
financial statements and footnotes for the years ended December 31, 1994, 1995
and 1996 included elsewhere in this report. The amounts set forth below are in
thousands, except per share data.
 
RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1994, 1995 AND 1996
 
     International operations accounted for approximately 69%, 73% and 73% of
the Company's total revenue during 1994, 1995 and 1996, respectively.
Consequently, the Company's results of operations were affected by movements in
foreign exchange rates. However, the Company enters into foreign exchange
forward contracts on firm intercompany balances in order to mitigate a portion
of the foreign exchange rate exposure.
 
     On September 25, 1996, the Company signed a definitive Asset Purchase
Agreement to sell its Open Service Solutions ("OSS") business to an affiliate of
J.F. Lehman & Company ("J.F. Lehman"). On March 19, 1997, the Company announced
the termination of its agreement with J.F. Lehman and the signing of a
non-binding letter of intent with M.D. Sass Investors Services, Inc. ("Sass"), a
17% shareholder of the Company, for the purchase by Sass of a 51% interest in
the OSS business. In connection with this transaction, the Company will receive
from Sass $5,100 in cash and will receive from the entity that operates the OSS
business (a) $25,000 in cash and (b) a promissory note in the amount of $25,000.
The cash payment of
 
                                       10
<PAGE>   12
 
$25,000 will be funded by a bank loan to the OSS business, secured by its
assets. The Company will continue to own 49% of the OSS business, subject to an
option granted to OSS to purchase up to one-fifth of the balance of the
Company's equity position. The transaction is subject to execution and delivery
of a definitive agreement and to the availability of financing, receipt of
approval from the Company's banks, compliance with the Company's financing
instruments and other customary closing conditions. As a result, no assurance
can be given that the transaction will be consummated.
 
  Software Revenue and Gross Margins
 
     Total 1996 software revenue increased $16,214 or 6% from 1995, as product
revenue increased $28,012 or 17% and service revenue decreased $11,798 or 10%.
Product and service revenue for 1996 included unfavorable foreign exchange
impacts of $3,700 and $3,400, respectively. The 1996 product revenue increase
was primarily attributable to volume increases and included $27,000 related to a
contract with Electronic Data Systems as systems integrator to the Rolls-Royce
Aerospace Group and Allison Engine Company and $11,200 related to a contract
with Peugeot SA, including Automobiles Peugeot and Citroen, while 1995 product
revenue included $11,900 related to contracts with the Airbus Consortium
(British Aerospace Airbus Limited, Aerospatiale S.N.I., and Daimler Benz
Aerospace Airbus GmbH). During 1996, revenue from the Company's CADDS and
product data management software products increased $17,600 or 17% and $16,000
or 56%, respectively, over 1995 primarily due to favorable customer response to
the Company's Electronic Product Definition products. Revenue from several of
the Company's older mechanical CAD software products declined by $5,400 or 20%
from 1995, as expected demand for these products declined. Service revenue
decreased primarily due to an unfavorable year over year foreign exchange
impact, continued lower maintenance revenue as a result of lower pricing on new
products and upgrades within the existing customer base, and decreased training
revenue, offset by increased consulting revenue.
 
     Total 1995 software revenue increased slightly from 1994, and included
favorable foreign exchange impacts of $5,900 and $7,400 on product and service
revenue, respectively. The 1995 product revenue included $11,900 related to
contracts with the Airbus Consortium (British Aerospace Airbus Limited,
Aerospatiale S.N.I. and Daimler Benz Aerospace Airbus GmbH) while 1994 product
revenue included $16,400 related to a contract with Rolls-Royce plc. Product
revenue increased slightly principally due to increases in CADDS software
products, offset by decreases in the Company's other product lines as the
Company transitioned to its newer products. Service revenue decreased slightly
from 1994, primarily due to continued lower maintenance revenue as a result of
lower unit prices as new products are introduced, offset by increased training
and consulting service revenue.
 
     Software product margins for 1996 were 91% compared to 90% and 81% for 1995
and 1994, respectively. The improvement in software product margins in 1996
primarily resulted from a decrease in amortization of previously capitalized
software costs, partially offset by increased royalties for software licensed
from third parties. The improvement in 1995 margins from 1994 primarily resulted
from a decrease in amortization of previously capitalized software costs.
 
     Services margins for 1996, 1995 and 1994 were 39%, 42% and 41%,
respectively. The decrease in services margins in 1996 was primarily due to
decreased maintenance margins resulting from competitive pricing pressures, and
decreased training margins. The improvement in 1995 margins from 1994 primarily
resulted from lower costs due to the full benefit of the 1994 reorganization of
software support into regional centers.
 
  Other Revenue and Gross Margins
 
     Other services revenue (representing the OSS business unit) for 1996
decreased $46,089 or 21% from 1995, and included an unfavorable year over year
foreign exchange impact of $3,200. The decrease was primarily due to the
expected continuing reduction in proprietary hardware services, which declined
approximately $41,700 or 31% year over year, as well as the disruption caused by
the September 25, 1996 agreement to sell the OSS business to J.F. Lehman.
 
                                       11
<PAGE>   13
 
     Other services revenue for 1995 decreased $66,985 or 23% from 1994. The
decrease was primarily due to the expected continuing reduction in hardware
services, which declined $60,996 or 30% year over year, offset by a favorable
year over year foreign exchange impact of $10,000.
 
     Other services margins for 1996, 1995 and 1994 were 23%, 30% and 32%,
respectively. The decreases in margins were attributable to several factors,
including the disruption caused by the Sepember 25, 1996 agreement to sell the
OSS business to J.F. Lehman, the recording of certain inventory reserve
provisions and a shift in the revenue mix towards system integration revenue
which contributes a lower margin.
 
  Selling and Administrative Expense
 
     Total selling and administrative expense for 1996 increased $2,455 or 2%
from 1995, and included a favorable year over year foreign exchange impact of
$2,600. The increase was primarily due to increased spending for marketing and
the cost of a special service bonus to the former CEO. Total selling and
administrative expense for 1995 decreased $14,712 or 9% from 1994, due to the
cost benefits associated with the resizing of the Company's administrative
operations. This decrease was partially offset by an unfavorable foreign
exchange impact for 1995 of $6,200. The decrease in other services selling and
administrative expense year over year results from a decrease in other services
revenue as a percentage of total revenue.
 
  Research, Development and Engineering Expense
 
     Software product research, development and engineering expense for 1996,
1995 and 1994 is net of amounts capitalized as software development costs of $0,
$0 and $1,545, respectively. Software product research, development and
engineering expenditures (software product research, development and engineering
expense plus capitalized software) as a percentage of total software revenue for
1996, 1995 and 1994 was 13%, 15% and 20%, respectively.
 
     Total 1996 research, development and engineering expense decreased $2,289
or 5% from 1995 primarily due to additional cost savings resulting from the
continued reallocation of development to the Company's development facility in
India. Total 1995 research, development and engineering expense decreased
$16,186 or 27% from the prior year. The 1995 decrease was primarily due to
reductions in costs as a result of the reorganization and refocus of research
and development activity, including reallocation of development to the Company's
development facility in India (opened in 1994), the elimination of managerial
positions while maintaining a focused software development capacity and the
elimination of non-strategic activities and product lines, offset by reduced
software capitalization.
 
  Non-recurring Charges
 
     The 1996 results include a non-recurring charge of $14,500 which represents
$3,500 of purchased in-process R&D associated with the acquisition of 3rd Angle
Ltd., a UK-based technology company, and $11,000 of restructuring costs
associated with the implementation of ongoing cost savings (primarily personnel
reductions and the closing of facilities). The 1996 results also include a
non-recurring charge of $5,000 associated with the write-off of fees and
expenses incurred in connection with the terminated agreement to sell the OSS
business to J.F. Lehman. There were no non-recurring charges in 1995 or 1994.
 
  Interest and Other Expense, Net
 
     Interest and other expense, net for 1996 decreased $14,118 or 31% from 1995
and decreased $4,757 or 10% in 1995 from 1994 due primarily to the redemption in
full of the $125,000 10 7/8% Senior Notes in the fourth quarter of 1995 (See
"Long-Term Liquidity" below) and a reduction in costs associated with the
Company's revolving line of credit.
 
  Income Taxes
 
     The provision for income taxes is lower than the statutory rate in all
periods primarily due to the benefit of prior year net operating loss
carryforwards (See Note 7 "Provision for Income Taxes" of Notes to Consolidated
Financial Statements).
 
                                       12
<PAGE>   14
 
  Extraordinary Charge
 
     During the fourth quarter of 1995, the Company recorded an extraordinary
charge relating to a redemption premium ($5,437) and fees ($2,493) associated
with the early retirement of the Company's $125,000 10 7/8% Senior Notes.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     The software industry segment in which the Company operates is subject to
continuing changes and significant competitive pressures. The Company faces
several risks in its business, some of which are beyond its control. The
following is a discussion of some of the risks which the Company faces.
 
     Potential Fluctuations of Quarterly Operating Results; Impact of
Significant Contracts.  The Company's quarterly operating results may vary
significantly depending on factors such as the timing of significant orders and
the timing of new product introductions by the Company and its competitors. The
majority of the Company's software product revenues in each quarter result from
orders booked in that quarter and a substantial portion of the Company's orders
and shipments typically occur during the last two weeks of each quarter so that
forecasting of revenue is uncertain. As expenses in the short term are incurred
in advance of expected revenues, the Company may not be able to reduce expenses
commensurately with an unanticipated shortfall in revenue in a given quarter.
 
     The Company has focused its direct software sales efforts primarily on
large customers. The Company expects this reliance on large customers to
continue into 1997. As the software and services provided under large contracts
affect the customer's entire enterprise and affect the core of the customer's
product development efforts, the purchase decisions are made at senior
management levels of the enterprise and the sales cycle is generally much longer
than is typically the case, making the timing of such orders more difficult to
anticipate. In addition, the customer's own design cycle and capital spending
budget will affect the timing of orders. A large customer's delay in making
purchase decisions, or the Company's failure to obtain one or more significant
contracts could have a material adverse impact on the orders and shipments
planned for a current or future quarter.
 
     The Company also markets its products in Eastern Europe and the People's
Republic of China where issues of governmental approval and hard currency
availability further lengthen the sales cycle and affect the predictability of
orders.
 
     Large contracts increasingly require the Company to provide additional
consulting and other services. At times, the customer's implementation schedule
may differ from the Company's expectations and the Company may incur costs to
fulfill its contractual commitments before the customer requests implementation
services.
 
     In addition, the Company has historically experienced a seasonal decline in
revenue in the first and third quarters of each fiscal year, primarily due to
capital budgeting cycles of customers and the European holiday schedule,
respectively.
 
     New Products, Technological Change and Market Pressures.  The Company
continues to devote substantial resources to the research, development,
acquisition and marketing of design automation, product data management and
workflow technologies, and believes that their acceptance by customers is
critical to the future success of the Company. However, the development of new
technology and products is made increasingly complex and uncertain, as the
Company expands its use of third party technology through licensing or
acquisition. There can be no assurance that the Company will be successful in
developing, acquiring or licensing, and marketing these new products, that
customers will accept them or that competitors will not develop products or
technologies which render the Company's products or technologies noncompetitive
or obsolete.
 
     In addition to new technology, competitors are constantly marketing their
products in new ways, with new pricing, combinations of products and service
options which may affect the Company's own pricing and packaging decisions and
margins. Also, competitors are aligning with new partners and buying technology
to
 
                                       13
<PAGE>   15
 
strengthen the breadth of their product offerings and reduce the Company's
distinctive breadth of product offerings.
 
     Dependence on Certain Industries.  The Company sells its products to
customers in a number of industries, but its product revenues are heavily
concentrated in the automotive, aerospace and shipbuilding industries and may be
adversely affected by reductions in capital spending in these industries, as
well as cyclical economic trends affecting these industries. The Company's
future revenues would also be adversely affected by future declines in sales to
its automotive, aerospace and shipbuilding customers. In addition, customers in
these industries tend to continue with a technology choice for long periods (an
entire development cycle) so that an opportunity lost at a given customer will
not become a new opportunity for several years.
 
     OSS Business.  The Company has signed a non-binding letter of intent to
sell a 51% interest in the OSS business. The Company's failure to complete this
sale and the related transactions, and/or disruptions to the business caused
while the sale is being consummated, could have an adverse impact on OSS revenue
and, thereby, affect the Company's overall operating results and cash flow. In
addition, the Company's inability to offset attrition in maintenance revenue
with increased systems integration and networking revenue, and to offset a
revenue decline with reduced costs, would have an adverse impact on the
financial performance of the OSS business and the Company.
 
     Possible Limitations on Net Operating Loss Carryforwards.  In the past, the
Company has incurred substantial net operating loss carryforwards ("NOLs") which
may reduce taxes owed on future taxable income (See Note 7, "Provision for
Income Taxes" of Notes to Consolidated Financial Statements). The Internal
Revenue Code of 1986, as amended (the "Code") places annual limitations on the
ability of a corporation to use NOLs to offset taxable income for taxable years
following a change of more than 50% of the ownership of a corporation. In 1996,
a change of more than 50% of the ownership of the corporation occurred, which
results in an annual limitation on the usage of NOLs of approximately $40,000 to
$50,000. Although the Company has computed its NOLs and reported them to the
Internal Revenue Service (the "IRS") in a manner that indicates that they
generally will be available to be used to offset the Company's taxable income in
future years, there is a significant possibility that the IRS will disagree with
the Company's determination of the amount of NOLs that could be so used. In such
event, if the IRS were to prevail, the use of a portion or all of the Company's
NOLs could be disallowed and the Company would realize taxable income at an
earlier time than would otherwise be the case. In such an event, the Company
would be required to pay increased taxes from cash flow and could be required
for financial reporting purposes to increase its future provisions for income
taxes, thereby reducing the Company's net income.
 
     Other Risks.  The Company faces other risks in common with others in the
software industry which could also impair the Company's future financial
performance. For example, the market for high technology stocks is extremely
volatile and can be affected by factors beyond the Company's control, such as
the performance of the Company's competitors, market conditions in the CAD/CAM
and PDM industries or general economic conditions. International sales are
subject to additional risks, including the fact that foreign countries could
impose additional withholding taxes or otherwise further tax the Company's
income, impose tariffs or adopt other restrictions on foreign trade; agreements
and intellectual property rights may be difficult to enforce through a foreign
country's legal system; and unfavorable exchange rate shifts may be difficult to
anticipate. Despite a significant reduction in the Company's long term
indebtedness, the Company remains highly leveraged and has a stockholders'
deficit which may place the Company at a competitive disadvantage. The risks
from competition, liquidity needs, loss or challenge to proprietary rights and
litigation described elsewhere in this report could also have an adverse effect
on future financial results.
 
SHORT-TERM LIQUIDITY AND CAPITAL RESOURCES
 
     As a result of the 1996 and previous restructurings, including the 1993
exit from the hardware resale business, the Company has substantial cash payment
obligations that are unrelated to its current operations. The Company expects to
make cash payments in respect of such liabilities of approximately $27,000 in
1997. The Company will record a non-recurring charge of approximately $7,000 in
the first quarter of 1997, related
 
                                       14
<PAGE>   16
 
primarily to completing the separation of the OSS business from the software
business. In addition, the Company expects to record a non-recurring charge of
approximately $12,000 in the second quarter of 1997 related to restructuring the
software business due principally to the Company's failure to meet its revenue
plan for the first quarter of 1997 and the resulting revisions to its 1997
business plan, as described below. The Company believes that cash generated from
operations, supplemented by borrowings under the Revolving Credit Facility
("Revolving Credit Facility") and from factoring arrangements which may be
entered into from time to time will be sufficient to fund such cash payments, as
well as debt service, normal working capital and other cash requirements.
 
     The Revolving Credit Facility provided for a revolving line of credit (the
"Revolving Credit Line") of $50,000 for working capital and for sinking fund
payments on the Company's 8% Convertible Subordinated Debentures (unpaid
principal balance of $54,110 at December 31, 1996), of which $20,000 is
available for letters of credit. Pursuant to the terms of the Revolving Credit
Facility, the Company has granted the lenders a security interest in all of the
Company's U.S. assets. Letters of credit outstanding at December 31, 1996 were
$8,521 and there were no borrowings outstanding. The Revolving Credit Facility
requires the Company to satisfy certain financial and other covenants. As a
result of the non-recurring charges of $19,500 in the fourth quarter of 1996
(See "Non-recurring Charges" above) and an expected non-recurring charge of
$7,000 in the first quarter of 1997, the Company would not have satisfied the
financial covenants of its Revolving Credit Facility. As a result, the Company
and its lending banks signed an amendment which modifies the financial covenants
through December 31, 1997. The Company also agreed with its banks that it would
amend the Revolving Credit Facility to provide for a borrowing base limitation
and would limit outstanding borrowings to $18,800, including letters of credit
($3,800 outstanding at March 27, 1997) until the facility is so amended. Loans
under the Revolving Credit Facility will bear interest at a Base Rate or
Eurodollar rate, as selected by the Company, plus an Applicable Margin. On
December 31, 1996, the rates ranged from 7.5% to 9.25%.
 
     Due to the substantial shortfall in revenue for the quarter ended March 30,
1997, the Company was unable to satisfy certain of the financial covenants, as
amended, under the Revolving Credit Facility (under which no borrowings were
outstanding) ("Bank Covenants"). On April 15, 1997, the Company reached an
agreement with its lending banks to waive the default in the Bank Covenants for
the quarter ended March 30, 1997, to amend the Bank Covenants to conform with
the Company's revised business plan for 1997, and to implement a borrowing base
limitation (the "April 1997 Amendment"). Pursuant to the terms of the April 1997
Amendment, the Company may borrow funds secured by the accounts receivable of
the Company, Computervision Pty. Limited (Australia), Computervision S.A.
(France), Computervision GmbH (Germany) and Computervision Limited (U.K.). Until
such time as the April 1997 Amendment is executed, the Company may borrow on its
U.S. accounts receivable ($8,800 at March 30, 1997). Thereafter, until the
security interests are perfected, the Company may borrow the lesser of the
borrowing base limitation and (i) $25,000 for the period from April 15, 1997 to
June 30, 1997, and (ii) $35,000 thereafter. In addition, the April 1997
Amendment also limits the borrowings outstanding at the end of each fiscal
quarter ($18,000 for the second quarter of 1997, $21,000 for the third quarter
of 1997 and $16,000 for each subsequent quarter), and increases the interest
rate to LIBOR plus 2.5% for borrowings of $25,000 or less and LIBOR plus 3% for
borrowings greater than $25,000.
 
     Because the Company's borrowings under the amended Revolving Credit
Facility will be limited to a fixed percentage of the Company's accounts
receivable, the Company's ability to fund its operations over the short-term is
dependent upon its success in achieving its revised business plan for 1997. If
the Company is unsuccessful in achieving its business plan, its short-term
liquidity will be adversely impacted, which could require a curtailment of
certain business activities that in turn could have a material adverse effect on
the Company's business.
 
     As discussed above, the Company has signed a non-binding letter of intent
regarding the sale of 51% of its equity interest in the OSS business. If the
transaction is completed, the Company expects to use the net proceeds to meet
short-term working capital needs. If the transaction is not completed, the
Company expects to continue to manage the OSS business.
 
     The indenture governing the Company's 8% Convertible Subordinated
Debentures requires the Company to make, by December 1 of each year commencing
in 1995 and ending in 2008, sinking fund payments of
 
                                       15
<PAGE>   17
 
$5,500 per year. The Company may, however, satisfy this sinking fund
requirement, in whole or in part, through certain redemptions, or purchases and
delivery to the indenture trustee for cancellation, of 8% Convertible
Subordinated Debentures. The December 1995 sinking fund requirement was
satisfied by delivery for cancellation of debentures held by the Company. The
December 1996 sinking fund requirement was satisfied in part by delivery for
cancellation of $4,525 principal amount of debentures held by the Company. The
remaining requirement was satisfied by purchase and delivery of $975 principal
amount of debentures.
 
     Despite a significant reduction in the Company's long term indebtedness,
the Company remains highly leveraged and has a stockholders' deficit. This
indebtedness requires the Company to dedicate a significant portion of its cash
flow from operations to service its indebtedness and makes the Company more
vulnerable to unfavorable changes in general economic conditions.
 
LONG-TERM LIQUIDITY
 
     The Company's principal long-term liquidity requirements are payments for
interest, previously accrued restructuring obligations and capital expenditures
as well as the repayment of the Senior Subordinated Notes which mature in 1999.
The Company expects to meet its long-term liquidity requirements, including
repayment of its Senior Subordinated Notes, through funds generated from
operations, bank borrowings, and sales of equity and/or debt securities. The
Company believes that it will require additional funds in 1999 to satisfy these
obligations and, as a result, will seek to obtain such funds through a sale of
equity and/or debt securities or other financing arrangements. However, no
assurances can be given that such funds will be available when required or on
terms favorable to the Company.
 
     On October 25, 1995, the Company completed a public offering of 13,800
shares of common stock at $12 per share. The net proceeds from this sale,
approximately $155,000, were applied on December 4, 1995 to the redemption in
full of the outstanding $125,000 Senior Notes due in 1997. The total cost of the
redemption, including the redemption premium and interest accrued to the
redemption date, was approximately $135,000.
 
     Since 1989, the Company has incurred substantial obligations in connection
with the restructuring of the Company. The Company estimates that it will be
required to make cash payments of approximately $27,000, $14,000 and $12,000 in
1997, 1998 and 1999, respectively, of which $11,000, $12,000 and $12,000,
respectively, relate to vacant or partially vacant leased premises, net of known
sublease receipts and assuming that there are no lump-sum settlements on any of
the leases. To the extent the Company is unable to negotiate additional
subleases on its excess real estate or negotiate favorable settlements, the
Company's total future cash needs to meet these rental obligations and
anticipated operating costs will be approximately $73,000 through 2011,
including the amounts stated above. Based upon current and expected real estate
conditions, the Company has reserved $61,500 in connection with its net vacant
facility obligations for financial reporting purposes as of December 31, 1996,
which it believes to be adequate.
 
OPERATIONS AND INVESTMENTS
 
     The Company generated $7,882 of cash from operations during 1996 compared
to generating $11,961 of cash from operations in 1995. During 1996, current
assets used cash of $7,309 and current liabilities used cash of $36,510. During
1995, current assets generated cash of $12,460 and current liabilities used cash
of $57,917. The year to year change in current assets was driven primarily by
the 1996 investment in accounts receivable. The year to year change in current
liabilities resulted primarily from a reduction in restructuring payments made.
 
     The Company expended $11,479 for property and equipment during 1996
compared to $9,172 in 1995. The increase was primarily due to increased
leasehold improvements and the timing of development software license purchases.
Other assets increased $643 in 1996 and decreased $2,521 in 1995. The change was
primarily due to an increase in amounts capitalized for software purchases in
1996.

                              REPORT OF MANAGEMENT
 
     The accompanying consolidated financial statements and related information
of Computervision Corporation and subsidiaries (the "Company") have been
prepared by management, which is responsible for their integrity and
objectivity. The statements have been prepared in conformity with generally
accepted accounting principles and necessarily include some amounts based on
management's best estimates and judgments.
 
     Management is also responsible for maintaining a system of internal
controls as a fundamental requirement for the operational and financial
integrity of results. The Company has established and maintains a system of
internal controls designed to provide reasonable assurance that the books and
records reflect the transactions of the Company and that its established
policies and procedures are carefully followed. The Company's internal control
system is based upon standard procedures, policies and guidelines and
organizational structures that provide an appropriate division of responsibility
and the careful selection and training of qualified personnel. Our internal
auditors monitor compliance with the system of internal controls by means of an
annual plan of internal audits. On an ongoing basis, the system of internal
controls is reviewed, evaluated and revised as necessary in light of the results
of constant management oversight, internal and independent audits, changes in
Computervision's business and other conditions.
 
     The Company's accompanying consolidated financial statements have been
audited by Arthur Andersen LLP, independent public accountants, whose audit was
made in accordance with generally accepted auditing standards. Management has
made available to Arthur Andersen LLP all of the Company's financial records and
related data, as well as the minutes of stockholders' and directors' meetings.
Furthermore, management believes that all representations made to Arthur
Andersen LLP during its audit were valid and appropriate. The Report of
Independent Public Accountants appears below.
 
     The Board of Directors exercises its oversight responsibility for the
consolidated financial statements through its Audit Committee, comprised of
Directors who are not employees of the Company. Periodically, the Committee
meets privately with the internal auditors and the independent auditors and
representatives of management to assure that each is carrying out its
responsibilities. To assure independence, Arthur Andersen LLP has full and free
access to the Audit Committee to discuss internal accounting control, auditing
and financial reporting matters.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Computervision Corporation:
 
     We have audited the accompanying consolidated balance sheets of
Computervision Corporation and subsidiaries as of December 31, 1996 and 1995,
and the related consolidated statements of income, stockholders' equity
(deficit) and cash flows for each of the three years in the period ended
December 31, 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
Computervision Corporation and subsidiaries as of December 31, 1996 and 1995,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1996 in conformity with generally
accepted accounting principles.
 
     Our audits were made for the purpose of forming an opinion on the basic
consolidated financial statements taken as a whole. The schedule listed in Item
14(a) (2) is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic consolidated financial
statements. The schedule has been subjected to the auditing procedures applied
in the audits of the basic consolidated financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic consolidated financial statements
taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
(1) ORGANIZATION AND RECAPITALIZATION
 
     The Company develops, produces and markets software and provides support
services that are designed to aid manufacturing companies in enhancing their
product development and manufacturing processes. The Company's principal
products include design automation and product data management software.
Manufacturers use the Company's software to design, enhance and modify their
products and to access, share and manage their product data collaboratively. The
Company's support services include implementation, consulting and training
services designed to assist customers in reengineering their product development
processes and in increasing productivity.
 
     In 1989, DR Holdings Inc. of Delaware ("DR Holdings") acquired the Company
(the "Acquisition") in a purchase transaction. In August 1992, the Company
completed a recapitalization (the "Recapitalization"), which included the sale
of $300,000 of common stock and $300,000 of notes to the public. The proceeds
were used to retire debt. In addition, a loan from Lehman Brothers Holdings Inc.
("Lehman Holdings") was retired through the payment of cash and the issuance of
common stock of the Company. As a result of the Recapitalization, and subsequent
liquidation of DR Holdings, the common stock of the Company owned by DR Holdings
was distributed to its creditors.
 
     On October 25, 1995, the Company completed a public offering of 13,800
shares of common stock at $12.00 per share. The net proceeds from this sale,
approximately $155,000, were applied on December 4, 1995 to the redemption in
full of the outstanding $125,000 Senior Notes due in 1997. The total cost of the
redemption, including the redemption premium and interest accrued to the
redemption date, was approximately $135,000.
 
  OPERATING ENVIRONMENT
 
     See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" for discussion of the Company's current operating
environment and revenue trends.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its domestic and foreign subsidiaries. All significant intercompany accounts
and transactions have been eliminated in consolidation.
 
  MANAGEMENT ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.
 
  REVENUE RECOGNITION
 
     In accordance with AICPA Statement of Position 91-1 "Software Revenue
Recognition", revenue from software sales is recognized at the time the product
is delivered, if collection is probable. Revenue from post-contract and other
services is deferred and recognized ratably over the contractual period. Revenue
from consulting and training services is recognized as the services are
provided.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
  TRANSLATION OF FOREIGN CURRENCIES AND HEDGING INSTRUMENTS
 
     Assets and liabilities of foreign subsidiaries are translated into U.S.
dollars at the period-end exchange rates, while equity accounts are translated
at historical rates. Revenues and expenses are translated at the average
exchange rates during the period.
 
     The Company enters into forward foreign exchange contracts to hedge firm
intercompany balances. The Company does not engage in speculation and,
therefore, the forward exchange contracts do not subject the Company to risk due
to exchange rate movements as gains and losses on these contracts offset losses
and gains on the assets or liabilities of the transactions being hedged. As of
December 31, 1996 and 1995, the Company had $9,933 and $1,451 of net forward
exchange contracts outstanding, 65% and 84% of which were in European
currencies, respectively. The forward exchange contracts generally have
maturities of three months or less.
 
  PROPERTY AND EQUIPMENT
 
     The Company provides for depreciation and amortization by charges to
operations on the straight-line method in amounts estimated to expense the cost
of buildings, equipment and improvements over their estimated useful lives as
follows:
 
<TABLE>
<CAPTION>
                               ASSET CLASSIFICATION                         USEFUL LIVES
        ------------------------------------------------------------------  ------------
        <S>                                                                 <C>
        Buildings and leasehold improvements..............................   3-30 years
        Production and test equipment.....................................    3-8 years
        Computer systems and spares.......................................    3-5 years
        Office equipment and other........................................    3-8 years
</TABLE>
 
     Maintenance and repairs are charged to operations as incurred. When
equipment and improvements are fully depreciated, sold or otherwise disposed of,
the asset cost and accumulated depreciation are removed from the accounts and
the resulting gain or loss, if any, is included in the results of operations.
 
  CAPITALIZATION OF SOFTWARE DEVELOPMENT COSTS
 
     In accordance with Statement of Financial Accounting Standards No. 86
("SFAS 86"), "Accounting for the Costs of Computer Software to Be Sold, Leased
or Otherwise Marketed", the Company has capitalized certain computer software
development costs. During the years ended December 31, 1996, 1995 and 1994 the
Company capitalized $0, $0 and $1,545 of software costs, respectively. The
capitalized software is being amortized over lives ranging from three to five
years. The Company charged to expense $14,215, $5,359 and $1,715 of amortization
of capitalized software costs for the years ended December 31, 1994, 1995 and
1996, respectively.
 
  ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
 
     In 1996, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of", with no material impact on the
financial position or results of operations.
 
  STOCK-BASED COMPENSATION
 
     Effective January 1, 1996, the Company adopted the provisions of Statement
of Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for
Stock-Based Compensation". The Company has elected to continue to account for
stock options at intrinsic value under APB Opinion No. 25 with disclosure of the
effects of fair value accounting on net income and earnings per share on a pro
forma basis (See Note 11 "Stock Plans").

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
  INCOME TAXES
 
     The Company adopted the liability method of accounting for income taxes
under Statement of Financial Accounting Standards No. 109 ("SFAS 109"),
"Accounting for Income Taxes" as of January 1, 1993 with no cumulative effect of
a change in accounting for income taxes on the reported results of operations.
 
  RECLASSIFICATIONS
 
     Certain prior year balances in the financial statements have been
reclassified to conform to the current year financial statement presentation.
 
  EARNINGS/LOSS PER SHARE
 
     Earnings/Loss Per Share for the years ended December 31, 1994, 1995 and
1996 have been computed based upon the weighted average number of shares of
Common Stock and equivalents outstanding, if dilutive, during the year. Fully
diluted net income per share for all periods has not been presented as it is not
materially different from primary net income per share. On October 25, 1995, the
Company completed a public offering of 13,800 shares of common stock. The net
proceeds of approximately $155,000 were applied on December 4, 1995 to the
redemption in full of the outstanding $125,000 Senior Notes due in 1997. If this
transaction had occurred as of January 1, 1995, the net earnings per share for
1995 would have been $0.55 vs the reported $0.43.
 
(3) CASH, CASH EQUIVALENTS AND FINANCIAL INSTRUMENTS
 
     The Company classifies all cash investments with an original maturity of
less than ninety days as cash equivalents and values them at cost which
approximates market. The Company's policy is to invest cash primarily in income
producing short-term money market instruments and to keep uninvested cash
balances at minimum levels.
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of temporary cash investments
and accounts receivable. As of December 31, 1996, the Company had no significant
concentrations of credit risk.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value: (i) forward foreign exchange contracts (used for hedging purposes)
were estimated by obtaining quotes from brokers and (ii) long-term debt was
estimated based on the closing market price of the issue for the Senior
Subordinated Notes and based upon the most recent quoted market prices for the
8% Convertible Subordinated Debentures.
 
     The estimated fair values of the Company's financial instruments at
December 31, 1995 and 1996 are as follows:

     The Company would not be able to sell its forward foreign exchange
contracts without exposing the Company to significant risk of movements in
foreign exchange rates. Also, certain financing agreements prohibit repurchase
or redemption of the long-term debt before its maturity.

</TABLE>
 
     The average amount of short-term borrowings outstanding during 1996 was
$1,256, with a maximum outstanding of $11,500. The weighted average interest
rates on December 31, 1996 and for the year then ended was 9.25%.
 
  NOTES PAYABLE TO BANKS
 
     Notes payable to banks at December 31, 1995 and 1996 consisted of
borrowings by the Company's international subsidiaries under certain of the
Company's lines of credit. Borrowings under such lines bear interest at
prevailing or negotiated rates.
 
  REVOLVING CREDIT ARRANGEMENTS
 
     On November 17, 1995, the Company entered into a three-year, $50,000 credit
facility (the "Revolving Credit Facility") with Bankers Trust Company (Fleet
Bank of Massachusetts later became a co-agent) to replace the existing Revolving
Credit Agreement.
 
     The Revolving Credit Facility provided for a revolving line of credit (the
"Revolving Credit Line") of $50,000 for working capital and for sinking fund
payments on the Company's 8% Convertible Subordinated Debentures (unpaid
principal balance of $54,110 at December 31, 1996), of which $20,000 is
available for letters of credit. Pursuant to the terms of the Revolving Credit
Facility, the Company has granted the lenders a security interest in all of the
Company's U.S. assets. Letters of credit outstanding at December 31, 1996 were
$8,521 and there were no borrowings outstanding. The Revolving Credit Facility
requires the Company to satisfy certain financial and other covenants. As a
result of the non-recurring charges of $19,500 in the fourth quarter of 1996
(See Note 5 "Non-recurring Charges") and an expected non-recurring charge of
$7,000 in the first quarter of 1997, the Company would not have satisfied the
financial covenants of its Revolving Credit Facility. As a result, the Company
and its lending banks signed an amendment which modifies the financial covenants
through December 31, 1997. The Company also agreed with its banks that it would
amend the Revolving Credit Facility to provide for a borrowing base limitation
and would limit outstanding borrowings to $18,800 including letters of credit
($3,800 outstanding at March 27, 1997) until the facility is so amended.

                           COMPUTERVISION CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
Loans under the Revolving Credit Facility will bear interest at a Base Rate or
Eurodollar rate, as selected by the Company, plus an Applicable Margin. On
December 31, 1996, the rates ranged from 7.5% to 9.25%.
 
     Due to the substantial shortfall in revenue for the quarter ended March 30,
1997, the Company was unable to satisfy certain of the financial covenants, as
amended, under the Revolving Credit Facility (under which no borrowings were
outstanding) ("Bank Covenants"). On April 15, 1997, the Company reached an
agreement with its lending banks to waive the default in the Bank Covenants for
the quarter ended March 30, 1997, to amend the Bank Covenants to conform with
the Company's revised business plan for 1997, and to implement a borrowing base
limitation (the "April 1997 Amendment"). Pursuant to the terms of the April 1997
Amendment, the Company may borrow funds secured by the accounts receivable of
the Company, Computervision Pty. Limited (Australia), Computervision S.A.
(France), Computervision GmbH (Germany) and Computervision Limited (U.K.). Until
such time as the April 1997 Amendment is executed, the Company may borrow on its
U.S. accounts receivable ($8,800 at March 30, 1997). Thereafter, until the
security interests are perfected, the Company may borrow the lesser of the
borrowing base limitation and (i) $25,000 for the period from April 15, 1997 to
June 30, 1997, and (ii) $35,000 thereafter. In addition, the April 1997
Amendment also limits the borrowings outstanding at the end of each fiscal
quarter ($18,000 for the second quarter of 1997, $21,000 for the third quarter
of 1997 and $16,000 for each subsequent quarter), and increases the interest
rate to LIBOR plus 2.5% for borrowings of $25,000 or less and LIBOR plus 3% for
borrowings greater than $25,000.
 
     Because the Company's borrowings under the amended Revolving Credit
Facility will be limited to a fixed percentage of the Company's accounts
receivable, the Company's ability to fund its operations over the short term is
dependent upon its success in achieving its revised business plan for 1997. If
the Company is unsuccessful in achieving its business plan, its short-term
liquidity will be adversely impacted, which could require a curtailment of
certain business activities that in turn could have a material adverse effect on
the Company's business.
 
  CONVERTIBLE SUBORDINATED DEBENTURES
 
     The 8% Convertible Subordinated Debentures due December 1, 2009 are
convertible into cash at the rate of 33.33% of the principal amount at any time
prior to maturity at the option of the holder. No material conversions occurred
during the years ended December 31, 1994, 1995 and 1996. At the time of the
Acquisition, the 8% Convertible Subordinated Debentures were revalued to reflect
their current market values. The discount is being amortized to interest expense
over the remaining life of the debentures. A sinking fund requirement to retire
$5,500 principal amount of debentures per year began in December 1995. The
December 1995 sinking fund requirement was satisfied by delivery for
cancellation of debentures held by the Company. The December 1996 sinking fund
requirement was satisfied in part by delivery for cancellation of $4,525
principal amount of debentures held by the Company. The remaining requirement
was satisfied by purchase and delivery of $975 principal amount of debentures.
 
  SENIOR NOTES AND SENIOR SUBORDINATED NOTES
 
     The Company's previous Senior Notes bore interest at 10 7/8% per annum with
semi-annual interest payments due February 15 and August 15, commencing February
15, 1993. The Senior Notes were to mature on August 15, 1997 and were redeemable
in whole or in part at the option of the Company on or after August 15, 1995, at
104.35% of the principal amount thereof and on or after August 15, 1996 at
102.175% of the principal amount thereof, in each case together with accrued
interest to the date of redemption.
 
     On October 25, 1995 the Company completed a public offering of 13,800
shares of common stock at $12 per share. The net proceeds from this sale,
approximately $155,000, were applied on December 4, 1995 to the redemption in
full of the outstanding $125,000 Senior Notes due in 1997. The total cost of the
redemption, including the redemption premium and interest accrued to the
redemption date, was approximately $135,000.

     The Senior Subordinated Notes bear interest at 11 3/8% per annum with
semi-annual interest payments due February 15 and August 15, commencing on
February 15, 1993. The Senior Subordinated Notes mature on August 15, 1999 and
are redeemable in whole or in part at the option of the Company on or after
August 15, 1997, at 101.896% of the principal amount thereof, and on or after
August 15, 1998 at 100% of the principal amount thereof, in each case together
with accrued interest to the date of redemption.
 
     The Senior Subordinated Note indenture contains certain restrictions on the
payment of annual dividends and specifies certain events of default.

(5) NON-RECURRING CHARGES
 
     The 1996 results include a non-recurring charge of $14,500 which includes
$3,500 related to the fair value of purchased in-process R&D associated with the
acquisition of 3rd Angle Ltd., a UK-based technology company. This in-process
R&D had not yet reached technological feasibility and had no alternative future
use. The balance relates to $11,000 of restructuring costs associated with the
implementation of ongoing cost savings (primarily personnel reductions of
approximately 100 positions in R&D, sales and marketing, and the closing of
facilities). The 1996 results also include a non-recurring charge of $5,000
associated with the write-off of fees and expenses incurred in connection with
the terminated agreement to sell the Open Service Solutions business to J.F.
Lehman & Company. There were no non-recurring charges in 1995 or 1994.
 
(6) CAPITAL LEASES, LEASE COMMITMENTS AND RENT EXPENSE

</TABLE>
 
     SFAS 109 requires recognition of income tax benefits for loss
carryforwards, credit carryforwards, and certain temporary differences. The net
tax benefits have been reduced by a valuation allowance as they do not satisfy
the recognition criteria set forth in SFAS 109. Of the valuation allowance at
December 31, 1996, $7,083 will be recorded directly in equity when realized
related to stock option benefits and minimum pension liability adjustments.
 
     For U.S. tax return purposes at December 31, 1996, the Company has $469,809
of loss carryforwards and $18,878 of federal income tax credits which should be
available to reduce future income tax liabilities. These loss carryforwards will
expire beginning in 2003 through 2011 and the federal credit carryforwards will
expire in 1997 through 2003. The Company also has $111,866 of foreign loss
carryforwards at December 31, 1996. These foreign loss carryforwards will expire
beginning in 1997.
 
     The NOLs and tax credit carryforwards generally should be available to be
carried forward to future years. However, Section 382 of the Internal Revenue
Code of 1986, as amended (the "Code"), contains provisions which limit a
corporation's use of NOLs and tax credits after a change of more than 50% of the
ownership of the corporation. Subject to these limitations, the NOLs generally
are available to offset a taxpayer's taxable income in future years. In 1996, a
change of more than 50% of the ownership of the corporation occurred which
results in an annual limitation on the usage of NOLs of approximately $40,000 to
$50,000. Although the Company has computed its NOLs and reported them to the
Internal Revenue Service (the "IRS") in a manner that indicates that they
generally will be available to be used to offset the Company's taxable income in
future years, there is a significant possibility that the IRS will disagree with
the Company's determination of the amount of NOLs that could be so used. In such
event, if the IRS were to prevail, the use of a portion or all of the Company's
NOLs could be disallowed.
 
     The U.S. federal statutory tax rate on corporations was 35% in 1994, 1995
and 1996. A reconciliation between the Company's effective tax rate (provision
for income taxes as a percentage of income before income taxes) and the
statutory tax rate is as follows:

investment funds in which the employee may elect to contribute pre-tax savings
and the Company's matching contribution on a tax deferred basis. Under the plan,
each participant may elect to withhold a percentage of their annual
compensation. The Company makes matching contributions to the plan based on the
employee's length of service with the Company. The matching contributions are
made on a fiscal year basis to participants who are employed by the Company as
of December 31 of each fiscal year. The matching contribution expense for the
years ended December 31, 1994, 1995 and 1996 was $2,417, $1,989 and $1,905,

     Three international plans had an accumulated benefit obligation in excess
of plan assets of $5,191 and $6,433 at December 31, 1995 and 1996, respectively.
 
     The following assumptions were used to determine the accrued pension cost
for the U.S. plan in 1995 and 1996, respectively: the discount rates for
computing the projected benefit obligation were 7.25% and 7.5%; the rate of
compensation increase was zero for both years since benefits were frozen; and
the annual rate of return on plan assets was 7.5% for both years. As a result of
reducing the discount rate for computing the projected benefit obligation at
December 31, 1995, the Company was required to record a minimum pension
liability adjustment of $8,540. The Company did not record the tax benefit on
this adjustment as realization was not assured. An adjustment of $546 was
recorded in 1996 to reflect the increase in the discount rate. The plan assets
consist primarily of guaranteed interest and investment contracts with insurance
companies and banks. The Company contributes all amounts deemed necessary on an
actuarial basis to provide the U.S. plan with assets sufficient to meet the
benefits to be paid to plan participants. The amounts are determined by an
independent actuary based on the Projected Unit Credit Actuarial Cost Method.
Based on the actuarial valuations, the Company contributed $4,062, $6,306 and
$4,919 to the plan during 1994, 1995 and 1996, respectively.
 
     The accrued international pension cost was actuarially computed using
assumptions applicable to each subsidiary plan and economic environment. The
following range of assumptions was used in the determination of the accrued
pension cost in 1995 and 1996, respectively: the discount rates for computing
the projected benefit obligation were 4.5% to 8.5% and 4.0% to 8.5%; the rates
of compensation increase were 3.5% to 6.0%

for both years; the rates of social security increases were 0.0% to 5.5% for
both years; and the annual rates of return on plan assets were 5.5% to 9.0% and
4.5% to 9.0%. Plan assets primarily consist of guaranteed interest and
investment contracts with insurance companies.
 
     The total expense for the defined contribution plans for the years ended
December 31, 1994, 1995 and 1996 was approximately $347, $117 and $60,
respectively.
 
  Officers Life Insurance and Supplementary Retirement Plan
 
     The Company had an Officers Life Insurance and Supplementary Retirement
Plan for certain former executives of the former Computervision. The full cost
of this plan has been accrued for in the Consolidated Balance Sheets. The
Company made retirement benefit payments of $294, $334 and $458 to certain
former executives under this plan for the years ended December 31, 1994, 1995
and 1996, respectively.
 
  Employment Agreements
 
     Russell E. Planitzer, Chairman of the Board of Directors and Kathleen A.
Cote, President and Chief Executive Officer, have each entered into employment
agreements with the Company which provide for severance payments in the event
their employment is terminated prior to the expiration of their employment
terms. The severance amounts range from $300 to $5,600, depending on the timing
and circumstances of the termination.
 
     All other executive officers have been afforded continuation of salary
protection for one year if their employment with the Company is involuntarily
terminated. The Company has entered into Retention Agreements with its corporate
officers and certain key employees that provide for a continuation of salary and
benefits in the event of a termination of employment under circumstances after a
change of control of the Company has occurred.
 
(11) STOCK PLANS
 
     The Company accounts for its stock issuance plans in accordance with
Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to
Employees". Effective January 1, 1996, the Company adopted the provisions of
SFAS 123, "Accounting for Stock-Based Compensation". The Company has elected to
continue to account for stock options at intrinsic value with disclosure of the
effects of fair value accounting on net income and earnings per share on a pro
forma basis.
 
  Restricted Stock Agreements
 
     During 1994, the Company received 300 shares of Common Stock from Lehman
Holdings on the condition that the Company grant the shares to four executive
officers under a Restricted Stock Agreement. The shares were issued without
charge to four executive officers and vested ratably over a twelve month period
ending September 1995. The Restricted Stock Agreement qualified as a
compensatory stock plan, with the deferred compensation cost of $771 recognized
ratably over the twelve month period from the issuance date.
 
  Stock Option Plan
 
     In June 1992, the Board of Directors adopted the Company's 1992 stock
option plan which provides for the grant of options to officers, employees, and
consultants of the Company and its subsidiaries. A total of 4,400 shares of
Common Stock was originally reserved for issuance under the Stock Option Plan.
The Board of Directors amended the plan in September 1994 to authorize and
reserve an additional 5,000 shares for grant under the plan. Options granted may
be either incentive or non-qualified options. The options generally expire ten
years from the date of grant and vest ratably over the first five years or four
years, as determined by the

Compensation Committee. The Company has amended its 1992 Stock Option Plan to
provide that 50% of the then unvested options of each option holder shall vest
immediately upon a change of control of the Company.
 
  Director Stock Option Plans
 
     In April 1993, the Board of Directors adopted the Company's 1993 Director
Stock Option Plan to encourage ownership in the Company by non-employee
Directors whose continued services are considered essential to the Company's
future progress and to provide them with further incentive to remain as
Directors of the Company. A total of 200 shares of Common Stock were reserved
for issuance under this plan. Options for 102 shares were granted, of which 100
shares remain outstanding under this plan. Options granted are non-qualified and
at the fair market value at the date of grant and vest ratably over a five year
period.
 
     In January 1995, the Board of Directors adopted a new Director Option Plan
which was approved by stockholders at the 1995 Annual Meeting of Stockholders.
An additional 400 shares have been reserved for issuance. Options for 106 shares
were granted in January 1995 in recognition of past service at an exercise price
of $5.00 (fair value at grant date) and vest ratably over three years. The Plan
provides that Directors will receive an annual option grant of 6 shares each
that will vest in one year. The 1995 Director Option Plan supersedes the 1993
Director Stock Option Plan.

     Consistent with SFAS 123, pro forma net income and earnings per share have
not been calculated for options granted prior to January 1, 1995. Pro forma
compensation cost may not be representative of that to be expected in future
years.
 
     The weighted average fair value of options granted was $4.41 for options
granted during 1995 and $5.43 for options granted during 1996. The values were
estimated on the date of grant using the Black-Scholes option pricing model with
the following weighted average assumptions used for grants in 1995 and 1996,
respectively; risk-free interest rates of 6.25% and 5.99%, expected dividend
yields of 0% for both periods, expected lives of 5 years for both years and
expected volatilities of 57% and 56%.

  Employee Stock Purchase Plan
 
     In April 1993, the Company established a domestic and an international
employee stock purchase plan for all employees covering a total of 750 shares of
the Company's Common Stock. The plans permit employees of the Company to
withhold up to 10% of their base compensation to purchase the Company's common
stock at a 15% discount from the market price. The first offering commenced on
July 1, 1993. Employees purchased 90 and 227 shares in 1995 and 1994,
respectively, for $264 and $671. The 1993 plans were closed in 1995.
 
     In April 1995, the Company established a new domestic and international
employee stock purchase plan for all employees covering a total of 1,000 shares
of the Company's Common Stock. The purchase terms are identical to the prior
plan. The first offering commenced July 1, 1995. Employees purchased 83 and 75
shares in 1996 and 1995, respectively, for $678 and $409. For pro forma
compensation expense, the weighted average fair value of shares sold in 1996 was
$2.83.
 
  Stock Warrants
 
     In connection with a 1993 amendment to the Revolving Credit Facility, the
Banks were issued a Common Stock purchase warrant that permits the Banks to
purchase 200 shares of the Company's common stock at an exercise price of $3.88
per share (fair market value at date of issuance) through December 31, 1998. One
bank exercised its warrant to purchase 92 shares in February 1996 for $356.

(12) RELATED PARTIES
 
     The following summarizes the significant related party transactions (See
also Note 15 "Subsequent Event"):
 
     Several directors provided consulting services to the Company in 1994, 1995
and 1996 for which they received fees during a year ranging from $6 to $44.
 
     The Company recognized $11,200 of software product revenue from Peugeot SA
during the quarter ended March 31, 1996. A member of senior management of
Peugeot SA is also a director of the Company.
 
     At December 31, 1996, the Company had a loan of $200 outstanding to Mr.
Gnatovich of which $100 will be forgiven ratably over the next 4 years of
employment. The remaining $100 will be repaid by the deduction of $25 each year
from any bonus payments owed.
 
     In 1994, pursuant to separate, substantially identical Registration Rights
Agreements, the Company registered, under separate registration statements and
at the Company's sole expense, the shares of Common Stock owned by DR Holdings
and private purchasers of shares from Lehman Holdings. The Company is obligated
to maintain the Lehman Holdings purchasers' registration statement until May 31,
1997.
 
     In January 1993, Lehman Holdings (which at the time owned approximately 22%
of the outstanding Common Stock of the Company) provided a Revolving Loan
Facility to the Company which enabled the Company to borrow up to $25,000 if
necessary in connection with posting a bond or paying a settlement or judgment
in connection with certain antitrust litigation. In August 1993, Lehman Holdings
agreed to extend the termination date of the Revolving Loan Facility from
October 3, 1993 to July 3, 1994 for which it was paid an extension fee of $1,000
and a monthly availability fee of $250 through June 1994. In June 1994, the
Company borrowed approximately $7,500 under the Revolving Loan Facility to
settle the antitrust litigation and terminated the remainder of the commitment.
The Company paid interest at LIBOR plus 5% on this loan. The loan was repaid in
full on February 10, 1995.
 
     The Company's bylaws require that all transactions between the Company and
its officers, Directors and other affiliates must (i) be approved by a majority
of the members of the Company's Board of Directors and by a majority of the
disinterested members of the Company's Board and (ii) be on terms no less
favorable to the Company than could be obtained from third parties. In addition,
this policy requires that any loans by the Company to its officers, directors,
or other affiliates be for bona fide business purposes only. The terms of the
indentures associated with the Senior Subordinated Notes and the Revolving
Credit Facility also contain restrictions on transactions with affiliates.
 
(13) LITIGATION
 
     (1) On March 28, 1991, Joseph and Josephine Dieter, former stockholders of
the Company, brought suit against the Company, DR Holdings, DR Acquisition
Corporation, a former subsidiary of DR Holdings, Mr. Russell E. Planitzer,
Chairman of the Board of Directors of the Company, and Messrs. Don E. Ackerman
and Peter M. Castleman, former directors of the Company, in the Court of
Chancery of Delaware as both an individual and a class action (on behalf of all
persons, other than the defendants, who were stockholders of the Company on
December 28, 1989). The suit arises out of the merger between the Company and
certain subsidiaries of DR Holdings, and the related merger agreement. The suit
alleges, among other things, that, in connection with the acquisition of the
Company by DR Holdings, the Board of Directors of the Company breached its
fiduciary duties to the Company stockholders by (i) approving the merger which
plaintiffs allege was unfair to Company stockholders, and (ii) by not
withdrawing from the merger agreement and/or renegotiating the consideration
that was to be received by Company stockholders whose shares were not purchased
in the tender offer. The plaintiffs seek, among other things, an order granting
all Company stockholders as of December 28, 1989 damages in an undetermined
amount. The plaintiffs then filed an
 
                                       40
<PAGE>   42
 
                           COMPUTERVISION CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
amended and supplemented complaint which removed DR Holdings as a defendant
since it is in bankruptcy, and removed DR Acquisition Corporation since it had
been merged into the Company. The trial occurred in September of 1996. The
Company is in the process of filing post trial briefs and the Court is expected
to have the matter under submission by July 1997. Although the parties have
engaged in post-trial settlement discussions, it is not yet possible to predict
the outcome or quantify any possible exposure to the Company. If this lawsuit is
not settled, and the court awards the plaintiffs substantial monetary damages,
it could have a material adverse effect on the Company's financial condition and
results of operations.
 
     (2) In a letter dated June 11, 1993, the United States Environmental
Protection Agency ("EPA") notified the Company of its potential liability
pursuant to the Comprehensive Environmental Response Compensation and Liability
Act ("CERCLA") for a release of hazardous substances disposed of at the Shaffer
Landfill portion of the Ironhorse Park Superfund Site in Billerica,
Massachusetts ("Shaffer Site"). The Company was one of approximately 60
businesses and individuals to receive such a letter. The Company is cooperating
with approximately 30 other potentially responsible parties ("PRPs") who have
formed a group, and expects to participate in the common efforts of that group.
The Company has informed the EPA of its intent to cooperate with the other PRPs
in common efforts. The Company investigated the extent of its involvement with
the Shaffer Site and participated in a confidential mediation process which
allocated remedial costs among the members of the PRP group. The Company has
received information through the PRP group indicating that the anticipated costs
of completing the EPA's proposed remedy at the Shaffer Site is likely to range
between $20,000 and $33,000. After the PRPs failed to reach agreement with the
EPA regarding settlement, the Department of Justice ("DOJ") and the
Massachusetts Attorney General ("MAG") both filed complaints on January 5, 1995,
seeking past costs against 10 PRPs. The Company was not named. However, it could
be named later by the government and some of the named defendants have indicated
they will commence third-party actions against other PRPs, including the
Company, if ongoing negotiations do not result in a settlement. Negotiations
have been ongoing relative to several substantive matters and the Company cannot
predict at this time if any agreement on issues will be reached with the
government.
 
     (3) Several tax issues which pertain to Computervision tax returns for
years prior to 1988 (when Computervision was acquired by Prime Computer, Inc.)
remain outstanding. The most significant issue involves the qualification of a
domestic international sales corporation ("DISC") for tax years 1983 and 1984.
If the DISC is disqualified, the Company will be subject to additional tax and
interest in the range of $9,000 to $12,000 after the usage of net operating
losses. A trial on these issues was held before the Tax Court on October 25,
1994. On March 18, 1996 the Tax Court ruled in favor of the Company. On April
16, 1996 the Company filed a motion for Reconsideration with the Tax Court on
the one issue, which concerned whether income was reportable as capital gain or
ordinary income, on which the decision was unfavorable to the Company. The
Motion for Reconsideration was denied by the Judge on May 27, 1996. The Company
does not know whether the government will appeal the decision. Even if the
government does not appeal the decision, the Company will owe some tax and
interest on this case, but is also owed a refund on a related case. The
computation of the tax payment and the timing of the tax payment and refund have
not been determined. The Company's calculation of the adjustments resulting from
the Court's decision were reviewed by Counsel and submitted to the IRS on
November 12, 1996.
 
     (4) The Company is involved in numerous other legal proceedings and
litigation incidental to the normal course of the Company's business. The
Company believes that the ultimate disposition of these other proceedings and
litigation will not have a material adverse affect on the Company's financial
position.

(a) Operating income (loss) included non-recurring charges of $25,000, $515,800
    and $19,500 for the years ended December 31, 1992, 1993 and 1996,
    respectively.
 
(b) Loss from continuing operations for year ended December 31, 1992 also
    included charges of $64,050 associated with the Company's 1992
    Recapitalization.
 
(c) Pro forma earnings (loss) from continuing operations per share and pro forma
    net loss per share for the year ended December 31, 1992 have been adjusted
    to reflect the Company's issuance of 23,000 shares of common stock in 1992
    to retire certain long-term debt of the Company (see Note 1). The pro forma
    earnings (loss) from continuing operations per share and pro forma net
    earnings (loss) per share calculations, therefore, reflect, on a pro forma
    basis, the elimination of interest expense related to the retired portion of
    the debt and the issuance of the 23,000 shares.
 
(15) SUBSEQUENT EVENT
 
     On March 19, 1997, the Company announced the termination of its agreement
with J.F. Lehman & Company for the sale of its Open Service Solutions ("OSS")
business unit and the signing of a non-binding letter of intent with M.D. Sass
Investors Services, Inc. ("Sass"), a 17% shareholder of the Company, for the
purchase by Sass of a 51% interest in the OSS business. In connection with this
transaction, the Company will receive from Sass $5,100 in cash and will receive
from the entity that operates the OSS business (a) $25,000 in cash and (b) a
promissory note in the amount of $25,000. The cash payment of $25,000 will be
funded by a bank loan to the OSS business, secured by its assets. The Company
will continue to own 49% of the OSS business, subject to an option granted to
Sass to purchase up to one-fifth of the balance of the Company's equity
position. The transaction is subject to execution and delivery of a definitive
agreement and to the availability of financing, receipt of approval from the
Company's banks, compliance with the Company's financing instruments and other
customary closing conditions. As a result, no assurance can be given that the
transaction will be consummated.

                           COMPUTERVISION CORPORATION
                           --------------------------
                        
                             1992 STOCK OPTION PLAN
                             ----------------------

      (as amended September 15, 1994, April 18, 1995 and December 5, 1996)
       ------------------------------------------------------------------


     1. PURPOSE
        -------

         The purpose of this plan (the "Plan") is to secure for Computervision
Corporation (the "Company") and its shareholders the benefits arising from
capital stock ownership by employees and officers of, and consultants or
advisors to, the Company and its parent and subsidiary corporations who are
expected to contribute to the Company's future growth and success. Except where
the context otherwise requires, the term "Company" shall include the parent and
future subsidiaries of the Company as defined in Sections 424(e) and 424(f) of
the Internal Revenue Code of 1986, as amended or replaced from time to time (the
"Code"). Those provisions of the Plan which make express reference to Section
422 of the Code shall apply only to incentive Stock Options (as that term is
defined in the Plan).

     2. TYPES OF OPTIONS AND ADMINISTRATION
        -----------------------------------

     (a) TYPE OF OPTIONS. Options granted pursuant to the Plan shall be
authorized by action of the Board of Directors of the Company (or a Committee
designated by the Board of Directors) and may be either incentive stock options
("Incentive Stock Options") meeting the requirements of Section 422 of the Code
or non-statutory options which are not intended to meet the requirements of
Section 422 of the Code.

     (b) ADMINISTRATION. The Plan will be administered by the Board of Directors
of the Company, whose construction and interpretation of the terms and
provisions of the Plan shall be final and conclusive. The Board of Directors
may, in its sole discretion, grant options to purchase shares of the Company's
Common Stock ("Common Stock") and issue shares upon exercise of such options as
provided in the Plan. The Board shall have authority, subject to express
provisions of the Plan, to construe the respective option agreements and the
Plan, to prescribe, amend and rescind rules and regulations relating to the
Plan, to determine the terms and provisions of the respective option agreements,
which need not be identical, and to make all other determinations in the
judgment of the Board of Directors necessary or desirable for the administration
of the Plan. The Board of Directors may correct any defect or supply any
omission or reconcile any inconsistency in the Plan or in any option agreement
in the manner and to the extent it shall deem expedient to carry the Plan into
effect, and it shall be the sole and final just of such expediency. No director
or person acting pursuant to authority delegated by the Board of Directors shall
be liable for any action or determination under the Plan made in good faith. The
Board of Directors may, to the full extent permitted by or consistent with
applicable laws or regulations (including, without limitation, applicable state
law and

                                       1

<PAGE>   2

Rule 16b-3 promulgated under the Securities Exchange Act of 1934 (the "Exchange
Act"), or any successor rule ("Rule 16b-3"), delegate any or all of its powers
under the Plan to a committee (the "Committee") appointed by the Board of
Directors, and if the Committee is so appointed all references to the Board of
Directors in the Plan shall mean and relate to such Committee.

     (c) APPLICABILITY OF RULE 16b-3. Those provisions of the Plan which make
express reference to Rule 16b-3 shall apply only to such person as are required
to file reports under Section 16(a) of the Exchange Act (a "Reporting Person").

     3. ELIGIBILITY
        -----------  

     (a) GENERAL. Options may be granted to persons who are, at the time of
grant, employees, officers or directors of, or consultants or advisors to, the
Company; provided, that the class of employees to whom incentive Stock Options
may be granted shall be limited to all employees of the Company. A person who
has been granted an option may, if he or she is otherwise eligible, be granted
additional options if the Board of Directors shall so determine.

     (b) GRANT OF OPTIONS TO DIRECTORS AND OFFICERS. From and after the
registration of the Common Stock of the Company under the Exchange Act, the
selection of a director or an officer (as the terms "director" and "officer" are
defined for purposes of Rule 16b-3) as a recipient of an option, the timing of
the option grant, the exercise price of the option and the number of shares
subject to the option shall be determined either (i) by the Board of Directors,
of which all members shall be "disinterested persons" (as hereinafter defined),
or (ii) by two or more directors having full authority to act in the matter,
each of whom shall be a "disinterested person". For the purposes of the Plan, a
director shall be deemed to be a "disinterested person" only if such person
qualifies as a "disinterested person" within the meaning of Rule 16b-3, as such
term is interpreted from time to time.

     (c) YEARLY LIMITATION ON OPTION GRANTS. After April 1, 1995, the Board of
Directors may not grant to any individual in any year options to purchase more
than 700,000 shares of the Common Stock of the Company.


     4. STOCK SUBJECT TO PLAN
        ---------------------

     Subject to adjustment as provided in Section 15 below, the maximum number
of shares of Common Stock of the Company which may be issued and sold under the
Plan is 9,400,000 shares. If an option granted under the Plan shall expire or
terminate for any reason without having been exercised in full, the unpurchased
shares subject to such option shall again be available for subsequent option
grants under the Plan. If shares issued upon exercise of an option under the
Plan are tendered to the Company in payment of the exercise price of an option
granted under the Plan, such tendered shares shall again be available for
subsequent option grants under the Plan; provided that in no event shall 

                                       2

<PAGE>   3

(i) the total number of shares issued pursuant to the exercise of incentive
Stock Options under the Plan, on a cumulative basis, exceed the maximum number
of shares authorized for issuance under the Plan exclusive of shares made
available for issuance pursuant to this sentence or (ii) the total number of
shares issued pursuant to the exercise of options by Reporting Persons, on a
cumulative basis, exceed the maximum number of shares authorized for issuance
under the Plan exclusive of shares made available for issuance pursuant to this
sentence.

     5. FORMS OF OPTION AGREEMENTS
        --------------------------

     As a condition to the grant of an option under the Plan, each recipient of
an option shall execute an option agreement in such form not inconsistent with
the Plan as may be approved by the Board of Directors. Such option agreements
may differ among recipients.

     (a) GENERAL. The purchase price per share of stock deliverable upon the
exercise of an option shall be determined by the Board of Directors, PROVIDED,
HOWEVER, that (i) in the case of an Incentive Stock Option, the exercise price
shall not be less than 100% of the fair market value of such stock, as
determined by the Board of Directors, at the time of grant of such option, or
less than 110% of such fair market value in the case of options described in
Section 11(b); and (ii) in the case of non-statutory options, the exercise price
shall not be less than 50% of the fair market value of such stock, as determined
by the Board, at the time of grant of such option.

     (b) PAYMENT OF PURCHASE PRICE. Options granted under the Plan may provide
for the payment of the exercise price by delivery of cash or a check to the
order of the Company in an amount equal to the exercise price of such options,
or to the extent provided in the applicable option agreement, (i) by delivery to
the Company of shares of Common Stock of the Company already owned by the
optionee having a fair market value equal in amount to the exercise price of the
options being exercised, or (ii) by any combination of such methods of payment.
The fair market value of any shares of the Company's Common Stock or other
non-cash consideration which may be delivered upon exercise of an option shall
be determined by the Board of Directors. No shares of Common Stock may be
tendered or used in payment of the purchase price payable upon exercise of
options granted pursuant hereto, unless the tendered shares have been held by
the optionee for at least twelve (12) months.

     7. OPTION PERIOD
        -------------
 
     Each option and all rights thereunder shall expire on such date as shall be
set forth in the applicable option agreement, except that in the case of an
Incentive Stock Option, such date shall not be later than ten (10) years after
the date on which the option is

                                       3

<PAGE>   4

granted and, in all cases, options shall be subject to earlier termination as
provided in the Plan.

     8. EXERCISE OF OPTIONS
        -------------------

     Each option granted under the Plan shall be exercisable either in full or
in installments at such time or times, and during such period as shall be set
forth in the agreement evidencing such option, subject to the provisions of the
Plan.

     9. NON-TRANSFERABILITY OF OPTIONS
        ------------------------------

     Incentive Stock Options, and all options granted to Reporting Persons,
shall not be assignable or transferable by the person to whom they are granted,
wither voluntarily or by operation of law, except by will or the laws of descent
and distribution, and during the life of the optionee, shall be exercisable only
by the optionee; provided, however, that non-statutory options may be
transferred pursuant to a qualified domestic relations order (as defined in Rule
16b-3).

     10. EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER RELATIONSHIP
         ---------------------------------------------------------

     Except as provided in Section 11(d) with respect to Incentive Stock
Options, and subject to the provisions of the Plan, the Board of Directors shall
determine the period of time during which an optionee may exercise an option
following (i) the termination of the optionee's employment or other relationship
with the Company or (ii) the death or disability of the optionee. Such periods
shall be set forth in the agreement evidencing such option.

     11. Incentive Stock Options
         -----------------------

     Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:

     (a) EXPRESS DESIGNATION. All Incentive Stock Options granted under the Plan
shall, at the time of grant, be specifically designated as such in the option
agreement covering such Incentive Stock Options.

     (b) 10% SHAREHOLDER. If any employee to whom an Incentive Stock Option is
to be granted under the Plan, is at the time of the grant of such option, the
owner of stock possessing more than 10% of the total combined voting power of
all classes of stock of the Company (after taking into account the attribution
of stock ownership rules of Section 424(d) of the Code), then the following
special provisions shall be applicable to the Incentive Stock Option granted to
such individual:

                                       4

<PAGE>   5

          (i) The purchase price per share of the Common Stock subject to such
          Incentive Stock Option shall not be less than 110% of the fair market
          value of one share of Common Stock at the time of grant; and

          (ii) The option exercise period shall not exceed five years from the
          date of grant.

     (c) DOLLAR LIMITATION. For so long as the Code shall so provide, options
granted to any employee under the Plan (and any other Incentive Stock Option
plans of the Company) which are intended to constitute Incentive Stock Options
shall not constitute Incentive Stock Options to the extent that such options, in
the aggregate, become exercisable for the first time in any one calendar year
for shares of Common Stock with an aggregate fair market value (determined as of
the respective date or dates of grant) of more than $100,000.

     (d) TERMINATION OF EMPLOYMENT, DEATH OR DISABILITY. No Incentive Stock
Option may be exercised unless, at the time of such exercise, the optionee is,
and has been continuously since the date of grant of his or her option, employed
by the Company except that:

          (i) an Incentive Stock Option may be exercised within the period of
          three months after the date the optionee ceases to be an employee of
          the Company (or within such lesser period as may be specified in the
          applicable option agreement), provided, that the agreement with
          respect to such option may designate a longer exercise period and that
          the exercise after such three-month period shall be treated as the
          exercise of a non-statutory option under the Plan;

          (ii) if the optionee dies while in the employ of the Company, the
          Incentive Stock Option may be exercised by the person to whom it is
          transferred by will or the laws of descent and distribution within the
          period of one year after the date of death (or within such lesser
          period as may be specified in the applicable option agreement); and

          (iii) if the optionee becomes disabled (within the meaning of Section
          22(e)(3) of the Code or any successor provision thereto) while in the
          employ of the Company, the Incentive Stock Option may be exercised
          within the period of one year after the date the optionee ceases to be
          such an employee because of such disability (or within such lesser
          period as may be specified in the applicable option agreement).

     For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations). Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

     12. ADDITIONAL PROVISIONS
         ---------------------

     (a) ADDITIONAL OPTION PROVISIONS. The Board of Directors may, in its sole
discretion, include additional provisions in option agreements covering options
granted under the Plan, including without limitation restrictions on transfer,
repurchase rights, commitments to pay cash bonuses, to make, arrange for or
guarantee loans or to transfer other property to optionees upon exercise of
options, or such other provisions as shall be determined by the Board of
Directors; provided that such additional provisions shall not be inconsistent
with any other term or condition of the Plan, and such additional provisions
shall not cause any Incentive Stock Option granted under the Plan to fail to
qualify as an Incentive Stock Option within the meaning of Section 422 of the
Code.

     (b) ACCELERATION, EXTENSION, ETC. The Board of Directors may, in its sole
discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the
dates during which all, or any particular, option or options granted under the
Plan may be exercised; provided however, that no such extension shall be
permitted if it would cause the Plan to fail to comply with Section 422 of the
Code or with Rule 16b-3.

     13. GENERAL RESTRICTIONS
         --------------------

     (a) INVESTMENT REPRESENTATIONS. The Company may require any person to whom
an option is granted, as a condition of exercising such option, to give written
assurances in substance and form satisfactory to the Company to the effect that
such person is acquiring the Common Stock subject to the option for his or her
own account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as the Company deems
necessary or appropriate in order to comply with federal and applicable state
securities laws, or with covenants or representations made by the Company in
connection with any public offering of its Common Stock.

     (b) COMPLIANCE WITH SECURITIES LAWS. Each option shall be subject to the
requirement that if at any time, counsel to the Company shall determine that the
listing, registration or qualification of the shares subject to such option upon
any securities exchange or under any state or federal law, or the consent or
approval or that the disclosure of non-public information or the satisfaction of
any other condition is necessary as a condition of, or in connection with, the
issuance or purchase of shares thereunder, such option may not be exercised, in
whole or in part, unless such listing, registration, qualification, consent or
approval, or satisfaction of such condition shall have been effected or obtained
on conditions acceptable to the Board of Directors. Nothing herein shall be
deemed to require the Company to apply for or to obtain such listing,
registration or qualification, or to satisfy such condition.

                                       6

<PAGE>   7

     14. RIGHTS AS A SHAREHOLDER
         -----------------------
 
     The holder of an option shall have no rights as a shareholder with respect
to any shares covered by the option (including, without limitation, any rights
to receive dividends or non-cash distributions with respect to such shares)
until the date of issue of a stock certificate to him or her for such shares. No
adjustment shall be made for dividends or other rights for which the record date
is prior to the date such stock certificate is issued.

     15. ADJUSTMENT PROVISIONS FOR RECAPITALIZATIONS AND RELATED TRANSACTIONS
         --------------------------------------------------------------------
 
     (a) GENERAL. If, through or as a result of any merger, consolidation, sale
of all or substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar transaction. (i) the outstanding shares of Common Stock
are increased, decreased or exchanged for a different number or kind of shares
or other securities of the Company, or (ii) additional shares or new or
different shares of other securities of other securities of the Company or other
non-cash assets are distributed with respect to such shares of Common Stock or
other securities, an appropriate and proportionate adjustment may be made in (x)
the maximum number and kind of shares reserved for issuance under the Plan, (y)
the number and kind of shares or other securities subject to any then
outstanding options under the Plan, and (z) the price for each share subject to
any then outstanding options under the Plan, without changing the aggregate
purchase price as to which such options remain exercisable. Notwithstanding the
foregoing, no adjustment shall be made pursuant to this Section 15 if such
adjustment would cause the Plan to fail to comply with Section 422 of the Code
or with Rule 16b-3.

     (b) BOARD AUTHORITY TO MAKE ADJUSTMENTS. Any adjustments under this Section
15 will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final, binding
and conclusive. No fractional shares will be issued under the Plan on account of
any such adjustments.

     16. MERGER, CONSOLIDATION, ASSET SALE, LIQUIDATION, ETC.
         ----------------------------------------------------

     (a) CONSEQUENCES OF ACQUISITION EVENTS. Upon the occurrence of an
Acquisition Event (as defined below), or the execution by the Company of any
agreement to effect an Acquisition Event, the Board shall take any one or more
of the following actions with respect to then outstanding options: (i) provide
that outstanding options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof), provided that any such options substituted for incentive stock options
shall satisfy, in the determination of the Board, the requirements of Section
424(a) of the Code; (ii) upon written notice to the optionees, provide that all
then unexercised options will become exercisable in full as of a specified date
(the "Acceleration Date") prior to the Acquisition Event and will terminate
immediately prior to the consummation of such

                                       7

<PAGE>   8

Acquisition Event, except to the extent exercised by the optionee between the
Acceleration Date and the consummation of such Acquisition Event; or (iii) in
the event of an Acquisition Event under the terms of which holders of Common
Stock will receive upon consummation thereof a cash payment for each share of
Common Stock surrendered pursuant to such Acquisition Event (the "Acquisition
Price"), provide that all outstanding options shall terminate upon consummation
of such Acquisition Event and each optionee shall receive, in exchange therefor,
a cash payment equal to the amount (if any) by which (A) the Acquisition Price
multiplied by the number of shares of Common Stock subject to such outstanding
Options (whether or not then exercisable), exceeds (B) the aggregate exercise
price of such Options. An "Acquisition Event" shall mean: (i) any merger or
consolidation which results in the voting securities of the Company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving or
acquiring entity) less than 50% of the combined voting power of the voting
securities of the Company or such surviving or acquiring entity outstanding
immediately after such merger or consolidation; (ii) any sale of all or
substantially all of the assets of the Company; (iii) the complete liquidation
of the Company; or (iv) the acquisition of "beneficial ownership" (as defined in
Rule 13d-3 under the Exchange Act) of securities of the Company representing 40%
or more of the combined voting power of the Company's then outstanding
securities (other than through a merger or consolidation or an acquisition of
securities directly from the Company) by any "person", as such term is used in
Sections 13(d) and 14(d) of the Exchange Act other than the Company, any trustee
or other fiduciary holding securities under an employee benefit plan of the
Company, or any corporation owned directly or indirectly by the stockholders of
the Company in substantially the same proportion as their ownership of stock of
the Company.

     (b) SUBSTITUTE OPTIONS. The Company may grant options under the Plan in
substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company, or
one of its subsidiaries, of property or stock of the employing corporation. The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

     17. NO SPECIAL EMPLOYMENT RIGHTS
         ----------------------------

     Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment by
the Company or interfere in any way with the right of the Company at any time to
terminate such employment or to increase or decrease the compensation of the
optionee.

     18. OTHER EMPLOYEE BENEFITS
         -----------------------

                                       8

<PAGE>   9

     Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise will not constitute compensation with respect to which any
other employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

     19. AMENDMENT OF THE PLAN
         ---------------------

     (a) The Board of Directors may at any time, and from time to time, modify
or amend the Plan in any respect, except that if at any time the approval of the
shareholders of the Company is required under Section 422 of the Code or any
successor provision with respect to Incentive Stock Options, or under Rule
16b-3, the Board of Directors may not effect such modification or amendment
without such approval.


                                      9
<PAGE>   10

     (b) The termination or any modification or amendment of the Plan shall not,
without the consent of an optionee, affect his or her rights under an option
previously granted to him or her. With the consent of the optionee affected, the
Board of Directors may amend the outstanding option agreements in a manner not
inconsistent with the Plan. The Board of Directors shall have the right to amend
or modify (i) the terms and provisions of the Plan and of any outstanding
Incentive Stock Options granted under the Plan to the extent necessary to
qualify any or all such options for such favorable federal income tax treatment
(including deferral of taxation upon exercise) as may be afforded incentive
stock options under Section 422 of the Code and (ii) the terms and provisions of
the Plan and of any outstanding option to the extent necessary to ensure the
qualifications of the Plan under Rule 16b-3.

     20. WITHHOLDING
         -----------
   
     (a) The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan.

     (b) With the exception of officers of the Company who are designated as
"Section 16 Officers" by the Company, optionees shall have the right to elect to
have a portion of the shares of Common Stock to be issued on exercise of the
option withheld by the Company to satisfy all or any portion of any applicable
tax withholding requirements.


     21. CANCELLATION AND NEW GRANT OF OPTIONS, ETC.
         -------------------------------------------

     The Board of Directors shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, (i) the
cancellation of any or all outstanding options under the Plan and the grant in
substitution therefore of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
canceled options or (ii) the amendment of the terms of any and all outstanding
options under the Plan to provide an option exercise price per share which is
higher or lower than the ten-current exercise price per share of such
outstanding options.

     22. EFFECTIVE DATE AND DURATION OF THE PLAN
         ---------------------------------------

     (a) EFFECTIVE DATE. The Plan shall become effective when adopted by the
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve (12) months after the date of the Board's adoption of the Plan, no
options previously granted under the Plan shall be deemed to be Incentive Stock
Options and no Incentive Stock Options shall be granted thereafter. Amendments
to the Plan not requiring shareholder approval shall become effective when
adopted by the Board of Directors; amendments requiring shareholder

                                       10

<PAGE>   11

approval (as provided in Section 19) shall become effective when adopted by the
Board of Directors, but no Incentive Stock Option granted after the date of such
amendment shall become exercisable (to the extent that such amendment to the
Plan was required to enable the Company to grant such Incentive Stock Option to
a particular optionee) unless and until such amendment shall have been approved
by the Company's shareholders. If such shareholder approval is not obtained
within twelve months of the Board's adoption of such amendment, any Incentive
Stock Options granted on or after the date of such amendment shall terminate to
the extent that such amendment to the Plan was required to enable to the Company
to grant such option to a particular optionee. Subject to this limitation,
options may be granted under the Plan at any time after the effective date and
before the date fixed for termination of the Plan.

     (b) TERMINATION. Unless sooner terminated in accordance with Section 16,
the Plan shall terminate with respect to Incentive Stock Options, upon the
earlier of (i) the close of business on the day next preceding the tenth
anniversary of the date of its adoption by the Board of Directors, or (ii) the
date on which all shares available for issuance under the Plan shall have been
issued pursuant to the exercise or cancellation of options granted under the
Plan. Unless sooner terminated in accordance with Section 16, the Plan shall
terminate with respect to options which are not Incentive Stock Options on the
date specified in (ii) above. If the date of termination is determined under (I)
above, then options outstanding on such date shall continue to have force and
effect in accordance with the provisions of the instruments evidencing such
options.

     23. PROVISION FOR FOREIGN PARTICIPANTS
         ----------------------------------

     The Board of Directors may, without amending the Plan, modify awards or
options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters.

     12. EMPLOYMENT TERMINATION.

          12.1 The employment of the Executive by the Company pursuant to this
Agreement shall terminate upon the occurrence of any of the following:

               (a) Expiration of the Full-time and Part-time Employment Periods
and the Consultation Period, whichever occurs later, unless extended by mutual
agreement.

               (b) At the election of the Company, for Cause, immediately upon
written notice by the Company to the Executive. For the purposes of this
Agreement, "Cause" shall mean:

               (i) the willful and continued failure of the Executive to perform
substantially the Executive's duties with the Company or one of its affiliates
(other than any such failure resulting from incapacity due to physical or mental
illness), after (1) a written demand for substantial performance is delivered to
the Executive by the Board or the Chief Executive Officer of the Company which
specifically identifies the manner in which the Board or Chief Executive Officer
of the Company believes that the Executive has not substantially performed the
Executive's

                                      -9-

<PAGE>   10

duties and (2) the failure by the Executive to remedy such substantial
non-performance within a reasonable period of time after receipt of such written
demand, or

               (ii) the willful engaging by the Executive in illegal conduct or
gross misconduct which is materially and demonstrably injurious to the Company.
For purposes of this provision, no act or failure to act, on the part of the
Executive, shall be considered "willful" unless it is done, or omitted to be
done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company. Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company. The cessation
of employment of the Executive shall not be deemed to be for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Board at a meeting of the Board called and held for
such purpose (after reasonable notice is provided to the Executive and the
Executive is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the good faith


                                      -10-

<PAGE>   11

opinion of the Board, the Executive is guilty of the conduct described in
subparagraph (i) or (ii) above, and specifying the particulars thereof in
detail.

               (c) Upon the death of the Executive or thirty days after
disability of the Executive. As used in this Agreement, the term "disability"
shall mean an event of disability entitling the Executive to coverage under the
Company's then current long-term disability plan.

          12.2 The Executive may elect to terminate his employment upon thirty
(30) days' prior written notice if the Company fails to make any payment due the
Executive under this Agreement and such failure is not cured within thirty (30)
days after the Executive gives written notice of such failure to the Company.

     13. Effect of Termination
         ---------------------

          13.1 TERMINATION FOR CAUSE. In the event the Executive's employment is
terminated for Cause pursuant to Section 12.1(b), the Company shall pay to the
Executive the salary and benefits accrued and payable through his last day of
employment as an employee or consultant, as the case may be.

          13.2 TERMINATION FOR DEATH OR DISABILITY. In the event the Executive's
employment is terminated by death prior to the expiration of the Full-time or
Part-time Employment Periods or the Consultation Period, the Company shall pay
to the estate of the Executive a lump sum amount equal to the sum of (a) the
salary, compensation or bonus which would otherwise be payable to the

                                      -11-

<PAGE>   12

Executive up to the end of the sixth month after the death occurs and (b) the
remaining unpaid balance of the Special Bonus. If the Executive's employment is
terminated because of disability, the Company shall pay to the Executive (a) in
biweekly installments, the salary, additional compensation and bonus otherwise
payable to him up to the end of the month in which the Executive becomes
eligible for the Company's long-term disability benefits plan and (b) a lump sum
equal to the remaining unpaid balance of the Special Bonus.

          13.3 TERMINATION FOR OTHER THAN CAUSE, DEATH OR DISABILITY. In the
event the Executive's employment is terminated other than for Cause, death or
disability or is terminated by the Executive in accordance with Section 12.2,

               (i) the Company shall pay to the Executive (a) in biweekly
installments, commencing within thirty (30) days of the last day of actual
employment, the Executive's then current salary through the later of the
expiration of the Full-time and Part-time Employment Periods and the
Consultation Period, as the case may be and (b) in a lump sum cash payment,
payable within thirty (30) days of the last day of actual employment, the
remaining unpaid balance of the Special Bonus; and

               (ii) until the expiration of the Full-time and Part-time
Employment Periods and the Consultation Period, whichever occurs later, the
Company shall continue to provide the Executive the benefits to which the
Executive and/or his family would be entitled to receive from the Company if his
employment or


                                      -12-

<PAGE>   13

consultancy, as the case may be, had not been so terminated. For purposes of
eligibility for any retiree benefits pursuant to any retirement plans or
programs, the Executive shall be considered to have remained employed until the
end of the Consultation Period, as the case may be, and to have retired on the
last day of such period.

     14. Gross-Up Payment.
         ----------------

          (a) Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any payment benefit or distribution by the
Company to or for the benefit of the Executive (whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise, but determined without regard to any additional payments required
under this Section 14) (a "Payment") would be subject to the excise tax imposed
by Section 4999 of the Internal Revenue Code ("Code") or any interest or
penalties are incurred by the Executive with respect to such excise tax (such
excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including, without limitation,
any income taxes (and any interest and penalties imposed with respect thereto)
and Excise Tax imposed upon the Gross-Up Payment, the

                                      -13-

<PAGE>   14

Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.

          (b) Subject to the provisions of Section 14(c), all determinations
required to be made under this Section 14, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by Arthur
Andersen & Co. or such other certified public accounting firm as may be
designated by the Executive (the "Accounting Firm"), which shall provide
detailed supporting calculations both to the Company and the Executive within 15
business days of the receipt of notice from the Executive that there has been a
Payment, or such earlier time as is requested by the Company. In the event that
the Accounting Firm is serving as accountant or auditor for any individual,
entity or group such that it is not independent, the Executive shall appoint
another nationally recognized accounting firm to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall
be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to
this Section 14(b), shall be paid by the Company to the Executive within five
days of the receipt of the Accounting Firm's determination. Any determination by
the Accounting Firm shall be binding upon the Company and the Executive. As a
result of the uncertainty in the application of Section 4999 of the Code

                                      -14-
<PAGE>   15

at the time of the initial determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made ("Underpayment"), consistent with the calculations
required to be made hereunder. In the event that the Company exhausts its
remedies pursuant to Section 14(c) and the Executive thereafter is required to
make a payment of any Excise Tax, the Accounting Firm shall determine the amount
of the Underpayment that has occurred and any such Underpayment shall be
promptly paid by the Company to or for the benefit of the Executive.

          (c) The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment. Such notification shall be given as soon as
practicable but no later than ten business days after the Executive is informed
in writing of such claim and shall apprise the Company of the nature of such
claim prior to the expiration of the 30-day period following the date on which
it gives such notice to the Company (or such shorter period ending on the date
that any payment of taxes with respect to such claim is due). If the Company
notifies the Executive in writing prior to the expiration of such period that it
desires to contest such claim, the Executive shall:

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

                                      -15-

<PAGE>   16

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

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

               (iv) permit the Company to participate in any proceedings
relating to such claim; PROVIDED, HOWEVER, that the Company shall bear and pay
directly all costs and expenses (including additional interest and penalties)
incurred in connection with such contest and shall indemnify and hold the
Executive harmless, on an after-tax basis, for any Excise Tax or income tax
(including interest and penalties with respect thereto) imposed as a result of
such representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 14(c), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forgo any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct the Executive to pay the tax claimed and sue for a
refund or contest the claim in any permissible manner, and the Executive agrees
to prosecute such contest to a determination before any administrative tribunal,
in a court of initial

                                      -16-

<PAGE>   17

jurisdiction and in one or more appellate courts, as the Company shall
determine; PROVIDED, HOWEVER, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount. Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issue raised by the Internal Revenue Service or any other taxing
authority.

          (d) If, after the receipt by the Executive of an amount advanced by
the Company pursuant to Section 14(c), the Executive becomes entitled to receive
any refund with respect to such claim, the Executive shall (subject to the
Company's complying with the requirements of Section 14(c)) promptly pay to the
Company the amount of such refund (together with any interest paid or credited
thereon after taxes applicable thereto). If, after the receipt by

                                      -17-

<PAGE>   18

the Executive of an amount advanced by the Company pursuant to Section 14(c), a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of 30 days after such determination, then such advance shall be forgiven and
shall not be required to be repaid and the amount of such advance shall offset,
to the extent thereof, the amount of Gross-Up Payment required to be paid.

     15. Non-Compete
         -----------

          (a) During the Full-time and Part-time Employment Periods and the
Consultation Period, the Executive will not directly or indirectly as an
individual proprietor, partner, stockholder, officer, employee, director, joint
venturer, investor, lender, or in any other capacity whatsoever (other than as
the holder of not more than one percent (1%) of the total outstanding stock of a
publicly held company), engage in the business of developing, producing,
marketing or selling products and/or services of the kind developed or being
developed, produced, marketed or sold by the Company while the Executive was
employed by the Company.

          (b) At the option of the Company, for a period of one year after the
termination or expiration of the Consultation Period, the Executive will not
directly or indirectly:

                                      -18-

<PAGE>   19

               (i) become an owner, partner, joint venturer, stockholder,
investor (other than as the holder of not more than one percent (1%) of the
total outstanding stock), officer, employee, or director of (x) any company or
entity that produces, markets or sells products and/or services of the kind
developed or being developed, produced, marketed or sold by the Company while
the Executive was employed by the Company ("CAD/CAM" products and/or services)
which is in the top 10 by CAD/CAM revenue (excluding the Company) at the time of
termination based upon the then current Dataquest or similar survey) (for
purposes of this agreement, a "Top Ten Company") or (y) any company or entity
that has direct contractual relationships with any Top Ten Company to develop or
design products to the specifications of any such Top Ten Company, or

               (ii) recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company;

          (c) If any restriction set forth in this Section 15 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

                                      -19-

<PAGE>   20

          (d) The restrictions contained in this Section 15 are necessary for
the protection of the business and goodwill of the Company and are considered by
the Executive to be reasonable for such purpose. The Executive agrees that any
breach of this Section 15 will cause the Company substantial and irrevocable
damage and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Company shall have the right to seek
specific performance and injunctive relief.

     16. Proprietary Information and Development.
         ---------------------------------------

          16.1 Proprietary Information.
               -----------------------

               (a) The Executive agrees that all information and know-how,
whether or not in writing, of a private, secret or confidential nature
concerning the Company's business or financial affairs (collectively,
"Proprietary Information") is and shall be the exclusive property of the
Company. By way of illustration, but not limitation, Proprietary Information may
include inventions, products, processes, methods, techniques, formulas,
compositions, compounds, projects, developments, plans, research data, clinical
data, financial data, personnel data, computer programs, and customer and
supplier lists. The Executive will not disclose any Proprietary Information to
others outside the Company or use the same for any unauthorized purposes without
written approval by the Board, either during or after his employment, unless and
until such Proprietary Information has become public

                                      -20-

knowledge or is otherwise publicly known or available outside the Company
without fault by the Executive.

               (b) The Executive agrees that all files, letters, memoranda,
reports, records, data, sketches, drawings, laboratory notebooks, program
listings, or other written, photographic, or other tangible material containing
Proprietary Information, whether created by the Executive or others, which shall
come into his custody or possession, shall be and are the exclusive property of
the Company to be used by the Executive only in the performance of his duties
for the Company.

               (c) The Executive agrees that his obligation not to disclose or
use information, know-how and records of the types set forth in paragraphs (a)
and (b) above, also extends to such types of information, know-how, records and
tangible property of customers of the Company or suppliers to the Company or
other third parties who may have disclosed or entrusted the same to the Company
or to the employee in the course of the Company's business.

          16.2 Developments.
               ------------

               (a) The Executive will make full and prompt disclosure to the
Company of all inventions, improvements, discoveries, methods, developments,
software, and works of authorship, whether patentable or not, which are created,
made, conceived or reduced to practice by the Executive or under his direction
or jointly with others during his employment by the

                                      -21-

<PAGE>   22

Company, whether or not during normal working hours or on the premises of the
Company (all of which are collectively referred to in this Agreement as
"Developments").

               (b) The Executive agrees to assign and does hereby assign to the
Company (or any person or entity designated by the Company) all his right, title
and interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications. However, this Section
16.2(b) shall not apply to Developments which do not relate to the present or
planned business or research and development of the Company and which are made
and conceived by the Executive not during normal working hours, not on the
Company's premises and not using the Company's tools, devices, equipment or
Proprietary Information.

               (c) The Executive agrees to cooperate fully with the Company,

procurement, maintenance and enforcement of copyrights and patents (both in the
United States and foreign countries) relating to Developments. The Executive

patent applications, declarations, oaths, formal assignments, assignment of
priority rights, and powers of attorney, which the Company may deem necessary or

                                      -22-

<PAGE>   23

          16.3 OTHER AGREEMENTS. The Executive hereby represents that he is not
bound by the terms of any other agreement which will interfere or conflict with
the terms of this Agreement. The Executive further represents that his
performance of all the terms of this Agreement and as an employee of the Company
does not and will not breach any agreement to keep in confidence proprietary
information, knowledge or data acquired by him in confidence or in trust prior
to his employment with the Company. The representations contained in this
Section 16.3 are necessary for the protection of the business and goodwill of
the Company, and the Executive agrees that any breach of this Section has the
potential to cause the Company substantial and irrevocable damage, and
therefore, in the event of any such breach, the Company shall have the right to
immediately terminate this Agreement with no further obligations to the
Executive beyond his salary through his last day of actual work.

     17. Indemnification.
         ---------------

          (a) The Company agrees that if the Executive is made a party, or is
threatened to be made a party, to any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "Proceeding"), by reason of the
fact that he is or was a director, officer or employee of the Company or is or
was serving at the request of the Company as a director, officer, member,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, including service with

                                      -23-

<PAGE>   24

respect to employee benefit plans, whether or not the basis of such Proceeding
is the Executive's alleged action in an official capacity while serving as a
director, officer, member, employee or agent, the Executive shall be indemnified
and held harmless by the Company to the fullest extent permitted or authorized
by the Company's certificate of incorporation or bylaws or, if greater, by the
laws of the State of Delaware, against all cost, expense, liability and loss
(including, without limitation, attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid or to be paid in settlement), reasonably
incurred or suffered by the Executive in connection therewith, and such
indemnification shall continue as to the Executive even if he has ceased to be a
director, member, employee or agent of the Company or other entity and shall
inure to the benefit of the Executive's heirs, executors and administrators. The
Company shall advance to the Executive all reasonable costs and expenses
incurred by him in connection with a Proceeding within 20 days after receipt by
the Company of a written request for such advances. Such request shall include
an undertaking by the Executive to repay the amount of such advance if it shall
ultimately be determined that he is not entitled to be indemnified against such
costs and expenses.

          (b) Neither the failure of the Company (including its board of
directors, independent legal counsel or stockholders) to have made a

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (the "Agreement") made as of the 4th day of
September, 1996 as an amendment and restatement of the Agreement dated December
1, 1995 is entered into by Computervision Corporation, a Delaware corporation
with its principal place of business at 100 Crosby Drive, Bedford, Massa
chusetts 01730 (the "Company") and Kathleen A. Cote, 58 North Street, Lexington,
MA. 02173 (the "Employee").

     The Company desires to continue to employ the Employee, and the Employee
desires to continue to be employed by the Company, pursuant to the terms and
conditions of this Agreement. In consideration of the mutual covenants and
premises contained herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged by the parties hereto,
the parties agree as follows:

         1. TERMS OF EMPLOYMENT. The Company hereby agrees to employ the
Employee, and the Employee hereby accepts employment with the Company, upon the
terms set forth in this Agreement, for a three year period commencing on
September 1, 1996 (the "Com mencement Date") and ending on August 31, 1999 (the
"Termination Date") (such period, as it may be extended as provided in this
Agreement, the "Employment Period"), unless otherwise terminated or modified in
accordance with the provisions of Section 4 below. At any time prior to any
September 1st that is then twenty-four (24) months prior to the Termination Date
(as the Termination Date may be extended in accordance herewith), the Company in
its sole discretion may extend the then current Termination Date for a one year
period by providing the Employee with written notice to that effect. (Thus, for
example, the Company shall have the right to extend the current Termination Date
of August 31, 1999 to August 31, 2000 only if it provides written notice of its
election to extend prior to September 1, 1997. Similarly, if the Company does
elect to extend the Termination Date of August 31, 2000, it may further extend
the Termination Date to August 31, 2001 if it provides written notice of its
election to extend prior to September 1, 1998.)


     2. TITLE, CAPACITY.

          2.1 From September 1, 1996 through October 30, 1996 (the "Transition
Period"), the Employee shall serve as the President and Chief Operating Officer
of the Company and shall report to, and be subject to the supervision of, the
Chief

                                      -1-
<PAGE>   2

Executive Officer of the Company ("CEO"). From and after Novem ber 1, 1996, the
Employee shall serve as President and Chief Executive Officer and report to the

Massachusetts to fulfill her duties and responsibilities to the Company.

          2.2 The Employee hereby accepts such employment and agrees to
undertake such duties and responsibilities inherent in such positions and such
other duties and responsibilities as the CEO or the Board, as the case may be,
shall from time to time reasonably assign to her. The Employee agrees to devote
her entire business time, attention and energies to the business and interests
of the Company during the Employment Period, except with respect to incidental
business activities and outside directorships which shall be fully disclosed to
the Board by the Employee and approved by the Board prior to engagement in such
activities or directorships (other than outside directorships with Walden
University and Bay Networks, Inc. (hereinafter "Current Directorships") which
have been disclosed to and ap proved by the Board). None of any such
directorships or activi ties shall, in the sole determination of the Board,
cause a conflict of interest or interfere with the Employee's performance of her
duties hereunder. (The Company agrees that the Current Directorships do not
conflict or interfere with the Employee's performance of her duties hereunder.)
The Employee agrees to abide in all material respects by all lawful rules,
regulations, instructions, personnel practices and policies of the Company and
any changes therein which may be adopted from time to time by the Company,
except to the extent inconsistent with this Agreement. The Employee acknowledges

Employee, in biweekly installments, an annual base salary of $400,000 per annum
and, thereafter, the Company shall pay the Employee an annual base salary of
$600,000. Such salary shall be subject to increase from time to time as
determined by the Board, in its sole discretion, upon recommendation by the
Compensation Committee to the Board based upon a review that shall take place at
least yearly. Such salary shall not be reduced without the consent of the
Employee.

          3.2 ANNUAL INCENTIVE BONUS. Under the Company's Management Incentive
Plan (the "Plan"), the award of an annual incentive bonus to the Employee will

IPO will include both quantitative and qualitative goals

                                      -2-

year during the Employment Period, the incentive bonus opportunity may range
from 0 - 100% (0 - 200% in the event of over achievement) of annual base salary.
The Compensation Committee will evaluate each February the achievement of the
IPO's for the past fiscal year and recommend to the Board the Employee's bonus
award for such year, based upon the Employee's achievement of her IPOs and the
achievement of the corporate performance goals for such year. Each annual
incentive bonus shall be payable either in a lump sum, or in installments, as
determined by the Board, at the time or times the Company pays incentive bonus
compensation to its other key executives.

grant under the Company's 1992 Stock Option Plan of an option to purchase
200,000 shares of the Company's Common Stock having a fair market value as of

25% on each of the first four anniversaries of such Grant Date.

          3.4 ADOPTION/PARTICIPATION IN STOCK PLANS OR PROGRAMS, ETC. If during
the Employment Period, the Company shall adopt a stock purchase, restricted
stock, stock appreciation, bonus unit or similar plan or program for
participation by key executives of the Company, the Employee shall have the
opportunity to partici pate therein to the extent permitted by then current laws
and regulations.

          3.5 FRINGE BENEFITS. The Employee shall be entitled to participate in
all benefit programs that the Company currently has in place and/or establishes
and makes available for partici pation by key executives of the Company and, to
the extent not covered by such key executive programs, shall be entitled to
participate in all benefit programs that the Company currently has in place
and/or establishes and makes available for partici pation to its other
employees, if any, to the extent that the Employee's position, tenure, salary,
age, health and other qualifications make her eligible to participate,
including, but not limited to, four weeks' annual vacation and the officers'
perquisite program.

          Under the officers' perquisite program, the Employee shall have
available $30,000 per calendar year.

patent able or not, which are created, made, conceived or reduced to practice by
the Employee or under her direction or jointly with others during her employment
by the Company, whether or not during normal working hours or on the premises of
the Company (all of which are collectively referred to in this Agreement as
"Developments"). "Copyrightable Material" means all works of authorship,
including, but not limited to, books, papers, arti cles, software programs,
documentation, logic diagrams, teaching texts, videotapes, drawings and
graphics. The Employee acknowl edges that all such Copyrightable Material shall

               (b) The Employee agrees to assign and does hereby assign to the

<PAGE>   9

computer disks, access cards, keys and other items or materials developed for or

possession or under her control; and further agrees to delete and destroy any
information belonging to the Company from her personal computer.

               (d) The Employee has read, and understands and agrees to comply
with, the Company's Code of Conduct, including the guidelines and the appended

United States and foreign countries) relating to Developments. The Employee
shall sign all papers, including, without limitation, copyright applications,
patent applications, declarations, oaths, formal assignments, assignment of
priority rights, and powers of attorney, which the Company may deem necessary
or desirable in order to protect its rights and interests in any Development.
The Company shall pay the reasonable out-of-pocket expenses of the Employee

she breaches any of the covenants contained in Section 7.1 and 7.2 of this
Agreement, the damage suffered by the Company will be difficult to ascertain and
money damages alone will not afford an adequate remedy. In the event of such a
breach, in addition to such other remedies which may be provided by law, the

                           COMPUTERVISION CORPORATION

                         Management Retention Agreement


Mr. Barry F. Cohen
649 Sudbury Road
Concord, MA 01742

     Computervision Corporation (the "Company") recognizes that, as is the case
with many publicly-held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may
raise among key personnel, may result in the departure or distraction of key
personnel to the detriment of the Company, its stockholders and its customers.

     The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

     In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" (as
defined below).

     1. Certain Definitions.
        -------------------

     As used herein, the following terms shall have the following respective
meanings:

          (a) A "CHANGE IN CONTROL" shall occur or be deemed to have occurred
only if any of the following events occur:

               (i) any "person," as such term is used in Sections 13(d) and
          14(d) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"), (other than the Company, any trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Company, any corporation owned directly or indirectly by the
          stockholders of the Company in substantially the same proportion as
          their ownership of stock of the Company) is or becomes the "beneficial
          owner" (as defined in Rule 13d-3 under the Exchange Act), directly or
          indirectly, of securities of the Company representing 40% or more of
          the combined voting power of the

<PAGE>   2

          Company's then outstanding securities (other than as a result of the
          acquisition of such securities directly from the Company);

               (ii) during any period of two consecutive years (not including
          any period prior to the execution of this Agreement), individuals who
          at the beginning of such period constitute the Board and any new
          director (other than a director designated by a person who has entered
          into an agreement with the Company to effect a transaction described
          in paragraph (i), (iii) or (iv) of this Subsection) whose election by
          the Board or nomination for election by the Company's stockholders was
          approved by a vote of at least two-thirds (2/3) of the directors then
          still in office, who either were directors at the beginning of the
          period or whose election or nomination for election was previously so
          approved, cease for any reason to constitute at least a majority
          thereof; or

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

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

                    (b) "CAUSE" shall mean (i) an intentional act of fraud,
          embezzlement or theft in connection with your duties to the Company or
          in the course of your employment with the Company, (ii) your willful
          engaging in gross misconduct which is demonstrably and materially
          injurious to the Company, (iii) your willful and

                                      -2-
<PAGE>   3

          continued failure to perform substantially your duties with the
          Company or one of its affiliates (other than any such failure
          resulting from incapacity due to physical or mental illness), which
          such failure is not cured within 30 days after a written demand for
          substantial performance is delivered to you by the Board or the Chief
          Executive Officer of the Company which specifically identifies the
          manner in which the Board or Chief Executive Officer believes that you
          have not substantially performed your duties. For purposes of this
          Subsection, no act or failure to act on your part shall be deemed
          "willful" unless done or omitted to be done by you not in good faith
          and without reasonable belief that your action or omission was in the
          best interest of the Company.

                    (c) "DATE OF TERMINATION" shall have the meaning set forth
          in Section 3(c).

                    (d) "DISABILITY" shall be deemed to have occurred if, as a
          result of incapacity due to physical or mental illness, you shall have
          been absent from the full-time performance of your duties with the
          Company for six (6) consecutive months and, within thirty (30) days
          after written Notice of Termination by reason of disability is given
          to you, you shall not have returned to the full-time performance of
          your duties.

                    (e) "GOOD REASON" shall mean, without your express written
          consent, the occurrence after a Change in Control of the Company of
          any of the following circumstances unless, in the case of paragraphs
          (A), (C), (D), (F) or (G), such circumstances are fully corrected
          prior to the Date of Termination specified in the Notice of
          Termination given in respect thereof:

                              (A) any significant diminution in your position,
           duties, responsibilities, power, title or office as in effect
           immediately prior to a Change in Control;

                              (B) any reduction in your annual base salary as in
           effect on the date hereof or as the same may be increased from
           time to time;

                              (C) the failure by the Company to (i) continue in
          effect any material compensation or benefit plan in which you
          participate immediately prior to the Change in Control, unless an
          equitable arrangement (embodied in an ongoing substitute or

                                      -3-
<PAGE>   4

          alternative plan) has been made with respect to such plan, (ii)
          continue your participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both
          in terms of the amount of benefits provided and the level of your
          participation relative to other participants, as existed at the
          time of the Change in Control or (iii) award cash bonuses to you
          in amounts and in a manner substantially consistent with past
          practice in light of the Company's financial performance and your
          individual performance;

                              (D) the failure by the Company to continue to
          provide you with benefits substantially similar to those enjoyed
          by you under any of the Company's life insurance, medical, health
          and accident, or disability plans in which you were participating
          at the time of the Change in Control, the taking of any action by
          the Company which would directly or indirectly materially reduce
          any of such benefits, or the failure by the Company to provide
          you with the number of paid vacation days to which you are
          entitled on the basis of years of service with the Company in
          accordance with the Company's normal vacation policy in effect at
          the time of the Change in Control;

                              (E) any requirement by the Company or of any
          person in control of the Company that (i) the location at which
          you perform your principal duties for the Company be changed to a
          new location that is both outside a radius of 35 miles from your
          principal residence at the time of the Change in Control and more
          than 35 miles from the location at which you perform your
          principal duties for the Company at the time of the Change in
          Control or (ii) you travel on an overnight basis more than 90
          days in any consecutive 12-month period;

                              (F) the failure of the Company to obtain a
          reasonably satisfactory agreement from any successor to assume
          and agree to perform this Agreement, as contemplated in Section
          5; or

                              (G) any purported termination of your employment
          which is not effected pursuant to a Notice of Termination
          satisfying the requirements of Section 3(b), which purported
          termination shall not be effective for purposes of this
          Agreement.

                    (g) "NOTICE OF TERMINATION" shall have the meaning set forth
          in Section 3(b).

                    (i)     "TERM" shall have the meaning set forth in 
          Section 2.

     2. Term of the Agreement.
        ---------------------
  
     The term of this Agreement (the "Term") shall commence as of the date
hereof and shall continue in effect through December 31, 1999; provided,
however, that commencing on January l, 2000 and each January l thereafter, the
Term shall be automatically extended for one additional year unless, not later
than November 30 of the preceding calendar year, the Company shall have given
you written notice that the Term will not be extended; and provided further
that, if a Change in Control of the Company shall have occurred during the
original or extended Term, this Agreement shall continue in effect for a period
of not less than 24 months beyond the month in which such Change in Control
occurred.

     3. Employment Status; Termination Following Change in Control.
        ----------------------------------------------------------

          (a) No benefits shall be payable under this Agreement unless there has
been a Change in Control of the Company during the Term. You acknowledge that
this Agreement does not constitute a contract of employment or impose on the
Company any obligation to retain you as an employee. You may terminate your
employment at any time, with or without Good Reason. If your employment with the
Company terminates for any reason and subsequently a Change in Control shall
have occurred, you shall not be entitled to any benefits hereunder.

          (b) Any termination of your employment by the Company or by you
following a Change in Control of the Company during the Term shall be
communicated by written notice of termination that indicates the specific
provision in this Agreement relied upon and sets forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated ("Notice of Termination"). A Notice
of Termination shall be delivered to the other party hereto in accordance with
Section 6.

          (c) The "Date of Termination" shall mean (i) if your employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that you shall not have returned to the full-time performance of your
duties during such thirty (30) day period), and (ii) if your employment is
terminated by the Company for Cause, by you for Good Reason or for any other
reason (other than Disability), the date specified in the Notice of Termination
(which, in the case of a termination for Cause,

                                      -5-

<PAGE>   6

shall not be less than thirty (30) days from the date such Notice of Termination
is given and in the case of a termination for Good Reason shall not be less than
fifteen (15) nor more than sixty (60) days from the date such Notice of
Termination is given); provided, however, that if within fifteen (15) days after
any Notice of Termination is given, or, if later, prior to the Date of
Termination (as determined without regard to this proviso), the party receiving
such Notice of Termination notifies the other party that a dispute exists
concerning the termination, then the Date of Termination shall be the date on
which the dispute is finally determined, either by mutual written agreement of
the parties, by a binding arbitration award, or by a final judgment, order or
decree of a court of competent jurisdiction (which is not appealable or with
respect to which the time for appeal therefrom has expired and no appeal has
been perfected); and provided, further, that the Date of Termination shall be
extended by a notice of dispute only if such notice is given in good faith and
the party giving such notice pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, the
Company will continue to pay you your full compensation in effect when the
notice giving rise to the dispute was given (including, but not limited to, base
salary) and continue you as a participant in all compensation, benefit and
insurance plans in which you were participating when the notice giving rise to
the dispute was given, until the dispute is finally resolved in accordance with
this Subsection.

          (d) You shall be entitled to the benefits provided in Section 4 if a
Change in Control shall have occurred during the Term and your employment with
the Company is subsequently terminated or terminates within 24 months after such
Change in Control, unless such termination is (A) because of your death, (B) by
the Company for Disability or Cause , or (C) by you other than for Good Reason.

          (e) Your right to terminate your employment for Good Reason shall not
be affected by your incapacity due to physical or mental illness. Your continued
employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason under this Agreement.

     4. COMPENSATION UPON TERMINATION. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

          (a) DISABILITY. During any period that you fail to perform your
full-time duties with the Company as a result of incapacity due to physical or
mental illness, you shall continue to receive

                                      -6-

<PAGE>   7

base salary and all other earned compensation at the rate in effect at the
commencement of any such period (offset by all compensation payable to you under
the Company's disability plan or program or other similar plan during such
period) until your employment is terminated by reason of Disability. Thereafter,
or in the event your employment is terminated by reason of death, your benefits
shall be determined under the Company's long-term disability, retirement,
insurance and other compensation programs then in effect in accordance with the
terms of such programs.

          (b) CAUSE AND VOLUNTARY TERMINATION OTHER THAN FOR GOOD REASON. If
your employment shall be terminated by the Company for Cause or by you other
than for Good Reason following a Change in Control, the Company shall pay you
your full base salary and all other compensation through the Date of Termination
at the rate in effect at the time the Notice of Termination is given, no later
than the full fifth day following the Date of Termination, plus all other
amounts to which you are entitled under any compensation plan of the Company at
the time such payments are due, and the Company shall have no further
obligations to you under this Agreement.

          (c) TERMINATION WITHOUT CAUSE; VOLUNTARY TERMINATION FOR GOOD REASON.
If your employment with the Company is terminated by the Company (other than for
Cause, Disability or your death) or by you for Good Reason within 24 months
after a Change in Control, then you shall be entitled to the benefits below:

               (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

               (ii) the Company will pay as severance pay to you, at the time
specified in Subsection (d) below, a severance payment in an amount equal to
2.99 times the sum of (A) the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, and (B) 100% of the average annual incentive
bonus paid or payable to you by the Company for the two fiscal years ending
immediately prior to the fiscal year in which the Change of Control occurs;

                                      -7-

<PAGE>   8

               (iii) the Company shall pay to you, as incurred, to the extent
permitted by law, all legal fees and expenses reasonably incurred by you in
seeking to obtain or enforce any right or benefit provided by this Agreement;
and

               (iv) for a 36-month period after such termination, the Company
shall arrange to provide you with life, dental, and group health insurance
benefits on terms substantially similar to those applicable immediately prior to
the Notice of Termination. Notwithstanding the foregoing, the Company shall not
provide any benefit otherwise receivable by you pursuant to this paragraph (iv)
if an equivalent benefit is actually received by you from another employer
during the 36-month period following your termination, and any such benefit
actually received by you shall be reported to the Company.

          (d) The payments provided for in Subsection 4(c)(ii) shall be made in
seventy-eight (78) substantially equal bi-weekly installments over the
three-year period following the Date of Termination.

          (e) You shall not be required to mitigate the amount of any payment
provided for in this Section 4 by seeking other employment or otherwise, nor
shall the amount of any payment or benefit provided for in this Section 4 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

          (f) The Company's obligation to provide the installment payments and
benefits set forth in Subsection 4(c) are subject to your compliance in all
material respects with all agreements and covenants between you and the Company
set forth in the Employment Agreement attached hereto as Exhibit A, including
without limitation your agreement to refrain from (i) competing with the
Company, (ii) disclosing or using confidential or proprietary information of the
Company, or (iii) soliciting or otherwise inducing Company employees to leave
the employment of the Company.

     5. Successors; Binding Agreement.
        -----------------------------

          (a) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to

                                      -8-

<PAGE>   9

terminate your employment, except that for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination. As used in this Agreement, Company shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
your personal or legal representatives, executors, administrators, successors,
heirs, distributees, devisees and legatees. If you should die while any amount
would still be payable to you hereunder if you had continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to your devisee, legatee or other designee or if there
is no such designee, to your estate.

     6. NOTICE. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the

                           COMPUTERVISION CORPORATION

                         Management Retention Agreement


Ms. Kathleen A. Cote
58 North Street
Lexington, MA 02173

     Computervision Corporation (the "Company") recognizes that, as is the case
with many publicly-held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may
raise among key personnel, may result in the departure or distraction of key
personnel to the detriment of the Company, its stockholders and its customers.

     The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

     In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" (as
defined below).

     1. Certain Definitions.
        -------------------

     As used herein, the following terms shall have the following respective
meanings:

          (a) A "CHANGE IN CONTROL" shall occur or be deemed to have occurred
only if any of the following events occur:

               (i) any "person," as such term is used in Sections 13(d) and
          14(d) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"), (other than the Company, any trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Company, any corporation owned directly or indirectly by the
          stockholders of the Company in substantially the same proportion as
          their ownership of stock of the Company) is or becomes the "beneficial
          owner" (as defined in Rule 13d-3 under the Exchange Act), directly or
          indirectly, of securities of the Company representing 40% or more of
          the combined voting power of the

<PAGE>   2

          Company's then outstanding securities (other than as a result of the
          acquisition of such securities directly from the Company);

               (ii) during any period of two consecutive years (not including
          any period prior to the execution of this Agreement), individuals who
          at the beginning of such period constitute the Board and any new
          director (other than a director designated by a person who has entered
          into an agreement with the Company to effect a transaction described
          in paragraph (i), (iii) or (iv) of this Subsection) whose election by
          the Board or nomination for election by the Company's stockholders was
          approved by a vote of at least two-thirds (2/3) of the directors then
          still in office, who either were directors at the beginning of the
          period or whose election or nomination for election was previously so
          approved, cease for any reason to constitute at least a majority
          thereof; or

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

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

                    (b) "CAUSE" shall mean (i) an intentional act of fraud,
          embezzlement or theft in connection with your duties to the Company or
          in the course of your employment with the Company, (ii) your willful
          engaging in gross misconduct which is demonstrably and materially
          injurious to the Company, (iii) your willful and

                                      -2-
<PAGE>   3

          continued failure to perform substantially your duties with the
          Company or one of its affiliates (other than any such failure
          resulting from incapacity due to physical or mental illness), which
          such failure is not cured within 30 days after a written demand for
          substantial performance is delivered to you by the Board or the Chief
          Executive Officer of the Company which specifically identifies the
          manner in which the Board or Chief Executive Officer believes that you
          have not substantially performed your duties. For purposes of this
          Subsection, no act or failure to act on your part shall be deemed
          "willful" unless done or omitted to be done by you not in good faith
          and without reasonable belief that your action or omission was in the
          best interest of the Company.

                    (c) "DATE OF TERMINATION" shall have the meaning set forth
          in Section 3(c).

                    (d) "DISABILITY" shall be deemed to have occurred if, as a
          result of incapacity due to physical or mental illness, you shall have
          been absent from the full-time performance of your duties with the
          Company for six (6) consecutive months and, within thirty (30) days
          after written Notice of Termination by reason of disability is given
          to you, you shall not have returned to the full-time performance of
          your duties.

                    (e) "GOOD REASON" shall mean, without your express written
          consent, the occurrence after a Change in Control of the Company of
          any of the following circumstances unless, in the case of paragraphs
          (A), (C), (D), (F) or (G), such circumstances are fully corrected
          prior to the Date of Termination specified in the Notice of
          Termination given in respect thereof:

                              (A) any significant diminution in your position,
           duties, responsibilities, power, title or office as in effect
           immediately prior to a Change in Control;

                              (B) any reduction in your annual base salary as in
           effect on the date hereof or as the same may be increased from
           time to time;

                              (C) the failure by the Company to (i) continue in
          effect any material compensation or benefit plan in which you
          participate immediately prior to the Change in Control, unless an
          equitable arrangement (embodied in an ongoing substitute or

                                      -3-
<PAGE>   4

          alternative plan) has been made with respect to such plan, (ii)
          continue your participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both
          in terms of the amount of benefits provided and the level of your
          participation relative to other participants, as existed at the
          time of the Change in Control or (iii) award cash bonuses to you
          in amounts and in a manner substantially consistent with past
          practice in light of the Company's financial performance and your
          individual performance;

                              (D) the failure by the Company to continue to
          provide you with benefits substantially similar to those enjoyed
          by you under any of the Company's life insurance, medical, health
          and accident, or disability plans in which you were participating
          at the time of the Change in Control, the taking of any action by
          the Company which would directly or indirectly materially reduce
          any of such benefits, or the failure by the Company to provide
          you with the number of paid vacation days to which you are
          entitled on the basis of years of service with the Company in
          accordance with the Company's normal vacation policy in effect at
          the time of the Change in Control;

                              (E) any requirement by the Company or of any
          person in control of the Company that (i) the location at which
          you perform your principal duties for the Company be changed to a
          new location that is both outside a radius of 35 miles from your
          principal residence at the time of the Change in Control and more
          than 35 miles from the location at which you perform your
          principal duties for the Company at the time of the Change in
          Control or (ii) you travel on an overnight basis more than 90
          days in any consecutive 12-month period;

                              (F) the failure of the Company to obtain a
          reasonably satisfactory agreement from any successor to assume
          and agree to perform this Agreement, as contemplated in Section
          5; or

                              (G) any purported termination of your employment
          which is not effected pursuant to a Notice of Termination
          satisfying the requirements of Section 3(b), which purported
          termination shall not be effective for purposes of this
          Agreement.

                    (g) "NOTICE OF TERMINATION" shall have the meaning set forth
          in Section 3(b).

<PAGE>   5

                    (h)     "SEVERANCE PAYMENTS" shall have the meaning set
          forth in Section 4(c)(ii).

                    (i)     "TERM" shall have the meaning set forth in 
          Section 2.

     2. Term of the Agreement.
        ---------------------
  
     The term of this Agreement (the "Term") shall commence as of the date
hereof and shall continue in effect through December 31, 1999; provided,
however, that commencing on January l, 2000 and each January l thereafter, the
Term shall be automatically extended for one additional year unless, not later
than November 30 of the preceding calendar year, the Company shall have given
you written notice that the Term will not be extended; and provided further
that, if a Change in Control of the Company shall have occurred during the
original or extended Term, this Agreement shall continue in effect for a period
of not less than 24 months beyond the month in which such Change in Control
occurred.

     3. Employment Status; Termination Following Change in Control.
        ----------------------------------------------------------

          (a) No benefits shall be payable under this Agreement unless there has
been a Change in Control of the Company during the Term. You acknowledge that
this Agreement does not constitute a contract of employment or impose on the
Company any obligation to retain you as an employee. You may terminate your
employment at any time, with or without Good Reason. If your employment with the
Company terminates for any reason and subsequently a Change in Control shall
have occurred, you shall not be entitled to any benefits hereunder.

          (b) Any termination of your employment by the Company or by you
following a Change in Control of the Company during the Term shall be
communicated by written notice of termination that indicates the specific
provision in this Agreement relied upon and sets forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated ("Notice of Termination"). A Notice
of Termination shall be delivered to the other party hereto in accordance with
Section 6.

          (c) The "Date of Termination" shall mean (i) if your employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that you shall not have returned to the full-time performance of your
duties during such thirty (30) day period), and (ii) if your employment is
terminated by the Company for Cause, by you for Good Reason or for any other
reason (other than Disability), the date specified in the Notice of Termination
(which, in the case of a termination for Cause,

                                      -5-

<PAGE>   6

shall not be less than thirty (30) days from the date such Notice of Termination
is given and in the case of a termination for Good Reason shall not be less than
fifteen (15) nor more than sixty (60) days from the date such Notice of
Termination is given); provided, however, that if within fifteen (15) days after
any Notice of Termination is given, or, if later, prior to the Date of
Termination (as determined without regard to this proviso), the party receiving
such Notice of Termination notifies the other party that a dispute exists
concerning the termination, then the Date of Termination shall be the date on
which the dispute is finally determined, either by mutual written agreement of
the parties, by a binding arbitration award, or by a final judgment, order or
decree of a court of competent jurisdiction (which is not appealable or with
respect to which the time for appeal therefrom has expired and no appeal has
been perfected); and provided, further, that the Date of Termination shall be
extended by a notice of dispute only if such notice is given in good faith and
the party giving such notice pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, the
Company will continue to pay you your full compensation in effect when the
notice giving rise to the dispute was given (including, but not limited to, base
salary) and continue you as a participant in all compensation, benefit and
insurance plans in which you were participating when the notice giving rise to
the dispute was given, until the dispute is finally resolved in accordance with
this Subsection.

          (d) You shall be entitled to the benefits provided in Section 4 if a
Change in Control shall have occurred during the Term and your employment with
the Company is subsequently terminated or terminates within 24 months after such
Change in Control, unless such termination is (A) because of your death, (B) by
the Company for Disability or Cause , or (C) by you other than for Good Reason.

          (e) Your right to terminate your employment for Good Reason shall not
be affected by your incapacity due to physical or mental illness. Your continued
employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason under this Agreement.

     4. COMPENSATION UPON TERMINATION. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

          (a) DISABILITY. During any period that you fail to perform your
full-time duties with the Company as a result of incapacity due to physical or
mental illness, you shall continue to receive

                                      -6-

<PAGE>   7

base salary and all other earned compensation at the rate in effect at the
commencement of any such period (offset by all compensation payable to you under
the Company's disability plan or program or other similar plan during such
period) until your employment is terminated by reason of Disability. Thereafter,
or in the event your employment is terminated by reason of death, your benefits
shall be determined under the Company's long-term disability, retirement,
insurance and other compensation programs then in effect in accordance with the
terms of such programs.

          (b) CAUSE AND VOLUNTARY TERMINATION OTHER THAN FOR GOOD REASON. If
your employment shall be terminated by the Company for Cause or by you other
than for Good Reason following a Change in Control, the Company shall pay you
your full base salary and all other compensation through the Date of Termination
at the rate in effect at the time the Notice of Termination is given, no later
than the full fifth day following the Date of Termination, plus all other
amounts to which you are entitled under any compensation plan of the Company at
the time such payments are due, and the Company shall have no further
obligations to you under this Agreement.

          (c) TERMINATION WITHOUT CAUSE; VOLUNTARY TERMINATION FOR GOOD REASON.
If your employment with the Company is terminated by the Company (other than for
Cause, Disability or your death) or by you for Good Reason within 24 months
after a Change in Control, then you shall be entitled to the benefits below:

               (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

               (ii) the Company will pay as severance pay to you, at the time
specified in Subsection (d) below, a severance payment in an amount equal to
2.99 times the sum of (A) the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, and (B) 100% of the average annual incentive
bonus paid or payable to you by the Company for the two fiscal years ending
immediately prior to the fiscal year in which the Change of Control occurs;

                                      -7-

<PAGE>   8

               (iii) the Company shall pay to you, as incurred, to the extent
permitted by law, all legal fees and expenses reasonably incurred by you in
seeking to obtain or enforce any right or benefit provided by this Agreement;
and

               (iv) for a 36-month period after such termination, the Company
shall arrange to provide you with life, dental, and group health insurance
benefits on terms substantially similar to those applicable immediately prior to
the Notice of Termination. Notwithstanding the foregoing, the Company shall not
provide any benefit otherwise receivable by you pursuant to this paragraph (iv)
if an equivalent benefit is actually received by you from another employer
during the 36-month period following your termination, and any such benefit
actually received by you shall be reported to the Company.

          (d) The payments provided for in Subsection 4(c)(ii) shall be made in
seventy-eight (78) substantially equal bi-weekly installments over the
three-year period following the Date of Termination.

          (e) You shall not be required to mitigate the amount of any payment
provided for in this Section 4 by seeking other employment or otherwise, nor
shall the amount of any payment or benefit provided for in this Section 4 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

          (f) The Company's obligation to provide the installment payments and
benefits set forth in Subsection 4(c) are subject to your compliance in all
material respects with all agreements and covenants between you and the Company
set forth in the Employment Agreement dated September 4, 1996.

     5. Successors; Binding Agreement.
        -----------------------------

          (a) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to

                                      -8-

<PAGE>   9

terminate your employment, except that for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination. As used in this Agreement, Company shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
your personal or legal representatives, executors, administrators, successors,
heirs, distributees, devisees and legatees. If you should die while any amount
would still be payable to you hereunder if you had continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to your devisee, legatee or other designee or if there
is no such designee, to your estate.

     6. NOTICE. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the
Company, at Computervision Corporation, 100 Crosby Drive, Bedford, Massachusetts
01730, Attention: General Counsel, and to you at the address shown above or to
such other address as either the Company or you may have furnished to the other

be effective only upon receipt.

     7. Miscellaneous.
        -------------

          (a) The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

          (b) The validity, interpretation, construction and performance of this
Agreement shall be governed by the laws of the State of Delaware.

          (c) No waiver by you at any time of any breach of, or compliance with,
any provision of this Agreement to be performed by the Company shall be deemed a
waiver of that or any other provision at any subsequent time.

          (d) This Agreement may be executed in counterparts, each of which
shall be deemed to be an original but both of which together will constitute one
and the same instrument.

<PAGE>   10


          (e) Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law.

          (f) This Agreement and the Exhibits attached hereto set forth the

of the parties after the occurrence of a Change of Control and supersedes all
prior agreements, promises, covenants and arrangements, whether oral or written,

                           COMPUTERVISION CORPORATION

                         Management Retention Agreement


Mr. Anthony N. Fiore, Jr.
18 Goward Drive
Mansfield, MA 02048

     Computervision Corporation (the "Company") recognizes that, as is the case
with many publicly-held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may
raise among key personnel, may result in the departure or distraction of key
personnel to the detriment of the Company, its stockholders and its customers.

     The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

     In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" (as
defined below).

     1. Certain Definitions.
        -------------------

     As used herein, the following terms shall have the following respective
meanings:

          (a) A "CHANGE IN CONTROL" shall occur or be deemed to have occurred
only if any of the following events occur:

               (i) any "person," as such term is used in Sections 13(d) and
          14(d) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"), (other than the Company, any trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Company, any corporation owned directly or indirectly by the
          stockholders of the Company in substantially the


<PAGE>   2

          same proportion as their ownership of stock of the Company) is or
          becomes the "beneficial owner" (as defined in Rule 13d-3 under the
          Exchange Act), directly or indirectly, of securities of the Company
          representing 40% or more of the combined voting power of the
          Company's then outstanding securities (other than as a result of the
          acquisition of such securities directly from the Company);

               (ii) during any period of two consecutive years (not including
          any period prior to the execution of this Agreement), individuals who
          at the beginning of such period constitute the Board and any new
          director (other than a director designated by a person who has entered
          into an agreement with the Company to effect a transaction described
          in paragraph (i), (iii) or (iv) of this Subsection) whose election by
          the Board or nomination for election by the Company's stockholders was
          approved by a vote of at least two-thirds (2/3) of the directors then
          still in office, who either were directors at the beginning of the
          period or whose election or nomination for election was previously so
          approved, cease for any reason to constitute at least a majority
          thereof; or

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

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

                    (b) "Cause" shall mean (i) an intentional act of fraud, 
          embezzlement or theft in connection with your duties to the Company
          or in the course of your employment with the Company, (ii) your
          willful engaging in gross misconduct which is demonstrably and
          materially injurious to the Company, (iii) your willful and continued
          failure to perform substantially your duties with the Company or one
          of its affiliates (other than any such failure resulting from
          incapacity due to physical or mental illness), which such failure is
          not cured within 30 days after a written demand for substantial
          performance is delivered to you by the Board or the Chief Executive
          Officer of the Company which specifically identifies the manner in
          which the Board or Chief Executive Officer believes that you have not
          substantially performed your duties. For purposes of this Subsection,
          no act or failure to act on your part shall be deemed "willful"
          unless done or omitted to be done by you not in good faith and
          without reasonable belief that your action or omission was in the
          best interest of the Company.

                    (c) "DATE OF TERMINATION" shall have the meaning set forth
          in Section 3(c).

                    (d) "DISABILITY" shall be deemed to have occurred if, as a
          result of incapacity due to physical or mental illness, you shall have
          been absent from the full-time performance of your duties with the
          Company for six (6) consecutive months and, within thirty (30) days
          after written Notice of Termination by reason of disability is given
          to you, you shall not have returned to the full-time performance of
          your duties.

                    (e) "GOOD REASON" shall mean, without your express written
          consent, the occurrence after a Change in Control of the Company of
          any of the following circumstances unless, in the case of paragraphs
          (A), (C), (D), (F) or (G), such circumstances are fully corrected
          prior to the Date of Termination specified in the Notice of
          Termination given in respect thereof:

                              (A) any significant diminution in your position,
           duties, responsibilities, power, title or office as in effect
           immediately prior to a Change in Control;

<PAGE>   4

                              (B) any reduction in your annual base salary as in
           effect on the date hereof or as the same may be increased from
           time to time;

                              (C) the failure by the Company to (i) continue in
          effect any material compensation or benefit plan in which you
          participate immediately prior to the Change in Control, unless an
          equitable arrangement (embodied in an ongoing substitute or
          alternative plan) has been made with respect to such plan, (ii)
          continue your participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both
          in terms of the amount of benefits provided and the level of your
          participation relative to other participants, as existed at the
          time of the Change in Control or (iii) award cash bonuses to you
          in amounts and in a manner substantially consistent with past
          practice in light of the Company's financial performance and your
          individual performance;

                              (D) the failure by the Company to continue to
          provide you with benefits substantially similar to those enjoyed
          by you under any of the Company's life insurance, medical, health
          and accident, or disability plans in which you were participating
          at the time of the Change in Control, the taking of any action by
          the Company which would directly or indirectly materially reduce
          any of such benefits, or the failure by the Company to provide
          you with the number of paid vacation days to which you are
          entitled on the basis of years of service with the Company in
          accordance with the Company's normal vacation policy in effect at
          the time of the Change in Control;

                              (E) any requirement by the Company or of any
          person in control of the Company that (i) the location at which
          you perform your principal duties for the Company be changed to a
          new location that is both outside a radius of 35 miles from your
          principal residence at the time of the Change in Control and more
          than 35 miles from the location at which you perform your
          principal duties for the Company at the time of the Change in
          Control or (ii) you travel on an overnight basis more than 90
          days in any consecutive 12-month period;

<PAGE>   5

                              (F) the failure of the Company to obtain a
          reasonably satisfactory agreement from any successor to assume
          and agree to perform this Agreement, as contemplated in Section
          5; or

                              (G) any purported termination of your employment
          which is not effected pursuant to a Notice of Termination
          satisfying the requirements of Section 3(b), which purported
          termination shall not be effective for purposes of this
          Agreement.

                    (g) "NOTICE OF TERMINATION" shall have the meaning set forth
          in Section 3(b).

                    (h)     "SEVERANCE PAYMENTS" shall have the meaning set
          forth in Section 4(c)(ii).

                    (i)     "TERM" shall have the meaning set forth in 
          Section 2.

     2. Term of the Agreement.
        ---------------------
  
     The term of this Agreement (the "Term") shall commence as of the date
hereof and shall continue in effect through December 31, 1999; provided,
however, that commencing on January l, 2000 and each January l thereafter, the
Term shall be automatically extended for one additional year unless, not later
than November 30 of the preceding calendar year, the Company shall have given
you written notice that the Term will not be extended; and provided further
that, if a Change in Control of the Company shall have occurred during the
original or extended Term, this Agreement shall continue in effect for a period
of not less than 24 months beyond the month in which such Change in Control
occurred.

     3. Employment Status; Termination Following Change in Control.
        ----------------------------------------------------------

          (a) No benefits shall be payable under this Agreement unless there has
been a Change in Control of the Company during the Term. You acknowledge that
this Agreement does not constitute a contract of employment or impose on the
Company any obligation to retain you as an employee. You may terminate your
employment at any time, with or without Good Reason. If your employment with the
Company terminates for any reason and subsequently a Change in Control shall
have occurred, you shall not be entitled to any benefits hereunder.

                                      -5-
<PAGE>   6

          (b) Any termination of your employment by the Company or by you
following a Change in Control of the Company during the Term shall be
communicated by written notice of termination that indicates the specific
provision in this Agreement relied upon and sets forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated ("Notice of Termination"). A Notice
of Termination shall be delivered to the other party hereto in accordance with
Section 6.

          (c) The "Date of Termination" shall mean (i) if your employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that you shall not have returned to the full-time performance of your
duties during such thirty (30) day period), and (ii) if your employment is
terminated by the Company for Cause, by you for Good Reason or for any other
reason (other than Disability), the date specified in the Notice of Termination
(which, in the case of a termination for Cause,
shall not be less than thirty (30) days from the date such Notice of Termination
is given and in the case of a termination for Good Reason shall not be less than
fifteen (15) nor more than sixty (60) days from the date such Notice of
Termination is given); provided, however, that if within fifteen (15) days after
any Notice of Termination is given, or, if later, prior to the Date of
Termination (as determined without regard to this proviso), the party receiving
such Notice of Termination notifies the other party that a dispute exists
concerning the termination, then the Date of Termination shall be the date on
which the dispute is finally determined, either by mutual written agreement of
the parties, by a binding arbitration award, or by a final judgment, order or
decree of a court of competent jurisdiction (which is not appealable or with
respect to which the time for appeal therefrom has expired and no appeal has
been perfected); and provided, further, that the Date of Termination shall be
extended by a notice of dispute only if such notice is given in good faith and
the party giving such notice pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, the
Company will continue to pay you your full compensation in effect when the
notice giving rise to the dispute was given (including, but not limited to, base
salary) and continue you as a participant in all compensation, benefit and
insurance plans in which you were participating when the notice giving rise to
the dispute was given, until the dispute is finally resolved in accordance with
this Subsection.

<PAGE>   7

          (d) You shall be entitled to the benefits provided in Section 4 if a
Change in Control shall have occurred during the Term and your employment with
the Company is subsequently terminated or terminates within 24 months after such
Change in Control, unless such termination is (A) because of your death, (B) by
the Company for Disability or Cause , or (C) by you other than for Good Reason.

          (e) Your right to terminate your employment for Good Reason shall not
be affected by your incapacity due to physical or mental illness. Your continued
employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason under this Agreement.

     4. COMPENSATION UPON TERMINATION. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

     (a) DISABILITY. During any period that you fail to perform your full-time
duties with the Company as a result of incapacity due to physical or mental
illness, you shall continue to receive base salary and all other earned
compensation at the rate in effect at the commencement of any such period
(offset by all compensation payable to you under the Company's disability plan
or program or other similar plan during such period) until your employment is
terminated by reason of Disability. Thereafter, or in the event your employment
is terminated by reason of death, your benefits shall be determined under the
Company's long-term disability, retirement, insurance and other compensation
programs then in effect in accordance with the terms of such programs.

          (b) CAUSE AND VOLUNTARY TERMINATION OTHER THAN FOR GOOD REASON. If
your employment shall be terminated by the Company for Cause or by you other
than for Good Reason following a Change in Control, the Company shall pay you
your full base salary and all other compensation through the Date of Termination
at the rate in effect at the time the Notice of Termination is given, no later
than the full fifth day following the Date of Termination, plus all other
amounts to which you are entitled under any compensation plan of the Company at
the time such payments are due, and the Company shall have no further
obligations to you under this Agreement.

                                      -7-

<PAGE>   8

          (c) TERMINATION WITHOUT CAUSE; VOLUNTARY TERMINATION FOR GOOD REASON.
If your employment with the Company is terminated by the Company (other than for
Cause, Disability or your death) or by you for Good Reason within 24 months
after a Change in Control, then you shall be entitled to the benefits below:

               (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

               (ii) the Company will pay as severance pay to you, at the time
specified in Subsection (d) below, a severance payment in an amount equal to
2.99 times the sum of (A) the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, and (B) 100% of the average annual incentive
bonus paid or payable to you by the Company for the two fiscal years ending
immediately prior to the fiscal year in which the Change of Control occurs;

               (iii) the Company shall pay to you, as incurred, to the extent
permitted by law, all legal fees and expenses reasonably incurred by you in
seeking to obtain or enforce any right or benefit provided by this Agreement;
and

               (iv) for a 36-month period after such termination, the Company
shall arrange to provide you with life, dental, and group health insurance
benefits on terms substantially similar to those applicable immediately prior to
the Notice of Termination. Notwithstanding the foregoing, the Company shall not
provide any benefit otherwise receivable by you pursuant to this paragraph (iv)
if an equivalent benefit is actually received by you from another employer
during the 36-month period following your termination, and any such benefit
actually received by you shall be reported to the Company.

                                      -8-

<PAGE>   9

          (d) The payments provided for in Subsection 4(c)(ii) shall be made in
thirty-nine (39) substantially equal bi-weekly installments over the three-year
period following the Date of Termination.

          (e) You shall not be required to mitigate the amount of any payment
provided for in this Section 4 by seeking other employment or otherwise, nor
shall the amount of any payment or benefit provided for in this Section 4 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

          (f) The Company's obligation to provide the installment payments and
benefits set forth in Subsection 4(c) are subject to your compliance in all
material respects with all agreements and covenants between you and the Company
set forth in the Employment Agreement attached hereto as Exhibit A, including
without limitation your agreement to refrain from (i) competing with the
Company, (ii) disclosing or using confidential or proprietary information of the
Company, or (iii) soliciting or otherwise inducing Company employees to leave
the employment of the Company.

     5. Successors; Binding Agreement.
        -----------------------------

     (a) The Company will require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company expressly to assume and agree to perform this
Agreement to the same extent that the Company would be required to perform it if
no such succession had taken place. Failure of the Company to obtain an
assumption of this Agreement at or prior to the effectiveness of any succession
shall be a breach of this Agreement and shall constitute Good Reason if you
elect to terminate your employment, except that for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination. As used in this Agreement, Company shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
your personal or legal representatives, executors,

                                      -9-
<PAGE>   10

administrators, successors, heirs, distributees, devisees and legatees. If you
should die while any amount would still be payable to you hereunder if you had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to your devisee, legatee or
other designee or if there is no such designee, to your estate.

     6. NOTICE. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the
Company, at Computervision Corporation, 100 Crosby Drive, Bedford, Massachusetts
01730, Attention: General Counsel, and to you at the address shown above or to
such other address as either the Company or you may have furnished to the other

be effective only upon receipt.

     7. Miscellaneous.
        -------------

          (a) The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

          (b) The validity, interpretation, construction and performance of this
Agreement shall be governed by the laws of the State of Delaware.

          (c) No waiver by you at any time of any breach of, or compliance with,
any provision of this Agreement to be performed by the Company shall be deemed a
waiver of that or any other provision at any subsequent time.

          (d) This Agreement may be executed in counterparts, each of which
shall be deemed to be an original but both of which together will constitute one
and the same instrument.


<PAGE>   11
          (e) Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law.

          (f) This Agreement and the Exhibits attached hereto set forth the
entire agreement of the parties hereto in respect of the rights and obligations
of the parties after the occurrence of a Change of Control and supersedes all
prior agreements, promises, covenants and arrangements, whether oral or written,
by any officer, employee or representative of any party hereto in respect of a
Change of Control, PROVIDED, HOWEVER, that the terms and provisions of any
employment agreement now in effect or subsequently entered into between you and
the Company which governs the terms of your employment prior to or without
regard to a Change of Control shall continue to remain in full force and effect
and shall not be modified or superseded by this Agreement.

                           COMPUTERVISION CORPORATION

                         Management Retention Agreement


Mr. William Foniri
3 Pilgrim Road
Holliston, MA 01746

     Computervision Corporation (the "Company") recognizes that, as is the case
with many publicly-held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may
raise among key personnel, may result in the departure or distraction of key
personnel to the detriment of the Company, its stockholders and its customers.

     The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

     In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" (as
defined below).

     1. Certain Definitions.
        -------------------

     As used herein, the following terms shall have the following respective
meanings:

          (a) A "CHANGE IN CONTROL" shall occur or be deemed to have occurred
only if any of the following events occur:

               (i) any "person," as such term is used in Sections 13(d) and
          14(d) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"), (other than the Company, any trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Company, any corporation owned directly or indirectly by the
          stockholders of the Company in substantially the

<PAGE>   2

          same proportion as their ownership of stock of the Company) is or
          becomes the "beneficial owner" (as defined in Rule 13d-3 under the
          Exchange Act), directly or indirectly, of securities of the Company
          representing 40% or more of the combined voting power of the
          Company's then outstanding securities (other than as a result of the
          acquisition of such securities directly from the Company);

               (ii) during any period of two consecutive years (not including
          any period prior to the execution of this Agreement), individuals who
          at the beginning of such period constitute the Board and any new
          director (other than a director designated by a person who has entered
          into an agreement with the Company to effect a transaction described
          in paragraph (i), (iii) or (iv) of this Subsection) whose election by
          the Board or nomination for election by the Company's stockholders was
          approved by a vote of at least two-thirds (2/3) of the directors then
          still in office, who either were directors at the beginning of the
          period or whose election or nomination for election was previously so
          approved, cease for any reason to constitute at least a majority
          thereof; or

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

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

                    (b) "CAUSE" shall mean (i) an intentional act of fraud,
          embezzlement or theft in connection with your duties to the Company or
          in the course of your employment with the Company, (ii) your willful
          engaging in gross misconduct which is demonstrably and materially
          injurious to the Company, (iii) your willful and
          continued failure to perform substantially your duties with the
          Company or one of its affiliates (other than any such failure
          resulting from incapacity due to physical or mental illness), which
          such failure is not cured within 30 days after a written demand for
          substantial performance is delivered to you by the Board or the Chief
          Executive Officer of the Company which specifically identifies the
          manner in which the Board or Chief Executive Officer believes that you
          have not substantially performed your duties. For purposes of this
          Subsection, no act or failure to act on your part shall be deemed
          "willful" unless done or omitted to be done by you not in good faith
          and without reasonable belief that your action or omission was in the
          best interest of the Company.

                    (c) "DATE OF TERMINATION" shall have the meaning set forth
          in Section 3(c).

                    (d) "DISABILITY" shall be deemed to have occurred if, as a
          result of incapacity due to physical or mental illness, you shall have
          been absent from the full-time performance of your duties with the
          Company for six (6) consecutive months and, within thirty (30) days
          after written Notice of Termination by reason of disability is given
          to you, you shall not have returned to the full-time performance of
          your duties.

                    (e) "GOOD REASON" shall mean, without your express written
          consent, the occurrence after a Change in Control of the Company of
          any of the following circumstances unless, in the case of paragraphs
          (A), (C), (D), (F) or (G), such circumstances are fully corrected
          prior to the Date of Termination specified in the Notice of
          Termination given in respect thereof:

                              (A) any significant diminution in your position,
           duties, responsibilities, power, title or office as in effect
           immediately prior to a Change in Control;

           effect on the date hereof or as the same may be increased from
           time to time;

                              (C) the failure by the Company to (i) continue in
          effect any material compensation or benefit plan in which you
          participate immediately prior to the Change in Control, unless an
          equitable arrangement (embodied in an ongoing substitute or
          alternative plan) has been made with respect to such plan, (ii)
          continue your participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both
          in terms of the amount of benefits provided and the level of your
          participation relative to other participants, as existed at the
          time of the Change in Control or (iii) award cash bonuses to you
          in amounts and in a manner substantially consistent with past
          practice in light of the Company's financial performance and your
          individual performance;

                              (D) the failure by the Company to continue to
          provide you with benefits substantially similar to those enjoyed
          by you under any of the Company's life insurance, medical, health
          and accident, or disability plans in which you were participating
          at the time of the Change in Control, the taking of any action by
          the Company which would directly or indirectly materially reduce
          any of such benefits, or the failure by the Company to provide
          you with the number of paid vacation days to which you are
          entitled on the basis of years of service with the Company in
          accordance with the Company's normal vacation policy in effect at
          the time of the Change in Control;

                              (E) any requirement by the Company or of any
          person in control of the Company that (i) the location at which
          you perform your principal duties for the Company be changed to a
          new location that is both outside a radius of 35 miles from your
          principal residence at the time of the Change in Control and more
          than 35 miles from the location at which you perform your
          principal duties for the Company at the time of the Change in
          Control or (ii) you travel on an overnight basis more than 90
          days in any consecutive 12-month period;

          reasonably satisfactory agreement from any successor to assume
          and agree to perform this Agreement, as contemplated in Section
          5; or

                              (G) any purported termination of your employment
          which is not effected pursuant to a Notice of Termination
          satisfying the requirements of Section 3(b), which purported
          termination shall not be effective for purposes of this
          Agreement.

          Section 2.

     2. Term of the Agreement.
        ---------------------
  
     The term of this Agreement (the "Term") shall commence as of the date
hereof and shall continue in effect through December 31, 1999; provided,
however, that commencing on January l, 2000 and each January l thereafter, the
Term shall be automatically extended for one additional year unless, not later
than November 30 of the preceding calendar year, the Company shall have given
you written notice that the Term will not be extended; and provided further

occurred.

     3. Employment Status; Termination Following Change in Control.
        ----------------------------------------------------------

          (a) No benefits shall be payable under this Agreement unless there has
been a Change in Control of the Company during the Term. You acknowledge that
this Agreement does not constitute a contract of employment or impose on the
Company any obligation to retain you as an employee. You may terminate your
employment at any time, with or without Good Reason. If your employment with the
Company terminates for any reason and subsequently a Change in Control shall
have occurred, you shall not be entitled to any benefits hereunder.

                                      -5-

<PAGE>   6


          (b) Any termination of your employment by the Company or by you
following a Change in Control of the Company during the Term shall be
communicated by written notice of termination that indicates the specific
provision in this Agreement relied upon and sets forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated ("Notice of Termination"). A Notice
of Termination shall be delivered to the other party hereto in accordance with
Section 6.

          (c) The "DATE OF TERMINATION" shall mean (i) if your employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that you shall not have returned to the full-time performance of your
duties during such thirty (30) day period), and (ii) if your employment is
terminated by the Company for Cause, by you for Good Reason or for any other
reason (other than Disability), the date specified in the Notice of Termination
(which, in the case of a termination for Cause,shall not be less than thirty
(30) days from the date such Notice of Terminationis given and in the case of a
termination for Good Reason shall not be less than fifteen (15) nor more than
sixty (60) days from the date such Notice of Termination is given); provided,
however, that if within fifteen (15) days after any Notice of Termination is
given, or, if later, prior to the Date of Termination (as determined without
regard to this proviso), the party receiving such Notice of Termination notifies
the other party that a dispute exists concerning the termination, then the Date
of Termination shall be the date on which the dispute is finally determined,
either by mutual written agreement of the parties, by a binding arbitration
award, or by a final judgment, order or decree of a court of competent
jurisdiction (which is not appealable or with respect to which the time for
appeal therefrom has expired and no appeal has been perfected); and provided,
further, that the Date of Termination shall be extended by a notice of dispute
only if such notice is given in good faith and the party giving such notice
pursues the resolution of such dispute with reasonable diligence.
Notwithstanding the pendency of any such dispute, the Company will continue to
pay you your full compensation in effect when the notice giving rise to the
dispute was given (including, but not limited to, base salary) and continue you
as a participant in all compensation, benefit and insurance plans in which you
were participating when the notice giving rise to the dispute was given, until
the dispute is finally resolved in accordance with this Subsection.

<PAGE>   7

          (d) You shall be entitled to the benefits provided in Section 4 if a
Change in Control shall have occurred during the Term and your employment with
the Company is subsequently terminated or terminates within 24 months after such
Change in Control, unless such termination is (A) because of your death, (B) by
the Company for Disability or Cause , or (C) by you other than for Good Reason.

          (e) Your right to terminate your employment for Good Reason shall not
be affected by your incapacity due to physical or mental illness. Your continued
employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason under this Agreement.

     4. COMPENSATION UPON TERMINATION. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

          (a) DISABILITY. During any period that you fail to perform your
full-time duties with the Company as a result of incapacity due to physical or
mental illness, you shall continue to receive base salary and all other earned
compensation at the rate in effect at the commencement of any such period
(offset by all compensation payable to you under the Company's disability plan
or program or other similar plan during such period) until your employment is
terminated by reason of Disability. Thereafter, or in the event your employment
is terminated by reason of death, your benefits shall be determined under the
Company's long-term disability, retirement, insurance and other compensation
programs then in effect in accordance with the terms of such programs.

          (b) CAUSE AND VOLUNTARY TERMINATION OTHER THAN FOR GOOD REASON. If
your employment shall be terminated by the Company for Cause or by you other
than for Good Reason following a Change in Control, the Company shall pay you
your full base salary and all other compensation through the Date of Termination
at the rate in effect at the time the Notice of Termination is given, no later
than the full fifth day following the Date of Termination, plus all other
amounts to which you are entitled under any compensation plan of the Company at
the time such payments are due, and the Company shall have no further
obligations to you under this Agreement.

                                      -7-

          (c) TERMINATION WITHOUT CAUSE; VOLUNTARY TERMINATION FOR GOOD REASON.
If your employment with the Company is terminated by the Company (other than for
Cause, Disability or your death) or by you for Good Reason within 24 months
after a Change in Control, then you shall be entitled to the benefits below:

               (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

               (ii) the Company will pay as severance pay to you, at the time
specified in Subsection (d) below, a severance payment in an amount equal to
2.99 times the sum of (A) the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, and (B) 100% of the average annual incentive
bonus paid or payable to you by the Company for the two fiscal years ending
immediately prior to the fiscal year in which the Change of Control occurs;

               (iii) the Company shall pay to you, as incurred, to the extent
permitted by law, all legal fees and expenses reasonably incurred by you in
seeking to obtain or enforce any right or benefit provided by this Agreement;
and

               (iv) for an 18-month period after such termination, the Company
shall arrange to provide you with life, dental, and group health insurance
benefits on terms substantially similar to those applicable immediately prior to
the Notice of Termination. Notwithstanding the foregoing, the Company shall not
provide any benefit otherwise receivable by you pursuant to this paragraph (iv)
if an equivalent benefit is actually received by you from another employer
during the 18-month period following your termination, and any such benefit
actually received by you shall be reported to the Company.

                                      -8-

<PAGE>   9

          (d) The payments provided for in Subsection 4(c)(ii) shall be made in
thirty-nine (39) substantially equal bi-weekly installments over the
eighteen-month period following the Date of Termination.

          (e) You shall not be required to mitigate the amount of any payment
provided for in this Section 4 by seeking other employment or otherwise, nor
shall the amount of any payment or benefit provided for in this Section 4 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

          (f) The Company's obligation to provide the installment payments and
benefits set forth in Subsection 4(c) are subject to your compliance in all
material respects with all agreements and covenants between you and the Company
set forth in the Employment Agreement attached hereto as Exhibit A, including
without limitation your agreement to refrain from (i) competing with the
Company, (ii) disclosing or using confidential or proprietary information of the
Company, or (iii) soliciting or otherwise inducing Company employees to leave
the employment of the Company.

     5. Successors; Binding Agreement.
        -----------------------------

          (a) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to
terminate your employment, except that for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination. As used in this Agreement, Company shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
your personal or legal representatives, executors,

                                      -9-

should die while any amount would still be payable to you hereunder if you had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to your devisee, legatee or
other designee or if there is no such designee, to your estate.

     6. NOTICE. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or

     7. Miscellaneous.
        -------------

Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

          (b) The validity, interpretation, construction and performance of this
Agreement shall be governed by the laws of the State of Delaware.

          (c) No waiver by you at any time of any breach of, or compliance with,
any provision of this Agreement to be performed by the Company shall be deemed a
waiver of that or any other provision at any subsequent time.

shall be deemed to be an original but both of which together will constitute one
and the same instrument.

                           COMPUTERVISION CORPORATION

                         Management Retention Agreement


Mr. Rock S. Gnatovich
46 York Street
Lexington, MA 02173

     Computervision Corporation (the "Company") recognizes that, as is the case
with many publicly-held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may
raise among key personnel, may result in the departure or distraction of key
personnel to the detriment of the Company, its stockholders and its customers.

     The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

     In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" (as
defined below).

     1. Certain Definitions.
        -------------------

     As used herein, the following terms shall have the following respective
meanings:

          (a) A "CHANGE IN CONTROL" shall occur or be deemed to have occurred
only if any of the following events occur:

               (i) any "person," as such term is used in Sections 13(d) and
          14(d) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"), (other than the Company, any trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Company, any corporation owned directly or indirectly by the
          stockholders of the Company in substantially the

          same proportion as their ownership of stock of the Company) is or
          becomes the "beneficial owner" (as defined in Rule 13d-3 under the
          Exchange Act), directly or indirectly, of securities of the Company
          representing 40% or more of the combined voting power of the
          Company's then outstanding securities (other than as a result of the
          acquisition of such securities directly from the Company);

               (ii) during any period of two consecutive years (not including
          any period prior to the execution of this Agreement), individuals who
          at the beginning of such period constitute the Board and any new
          director (other than a director designated by a person who has entered
          into an agreement with the Company to effect a transaction described
          in paragraph (i), (iii) or (iv) of this Subsection) whose election by
          the Board or nomination for election by the Company's stockholders was
          approved by a vote of at least two-thirds (2/3) of the directors then
          still in office, who either were directors at the beginning of the
          period or whose election or nomination for election was previously so
          approved, cease for any reason to constitute at least a majority
          thereof; or

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

          securities immediately prior to such recapitalization, acquires 50% or

          securities; or

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

                    (b) "CAUSE" shall mean (i) an intentional act of fraud,
          embezzlement or theft in connection with your duties to the Company or
          in the course of your employment with the Company, (ii) your willful
          engaging in gross misconduct which is demonstrably and materially
          injurious to the Company, (iii) your willful and
          continued failure to perform substantially your duties with the
          Company or one of its affiliates (other than any such failure
          resulting from incapacity due to physical or mental illness), which
          such failure is not cured within 30 days after a written demand for
          substantial performance is delivered to you by the Board or the Chief
          Executive Officer of the Company which specifically identifies the
          manner in which the Board or Chief Executive Officer believes that you
          have not substantially performed your duties. For purposes of this
          Subsection, no act or failure to act on your part shall be deemed
          "willful" unless done or omitted to be done by you not in good faith
          and without reasonable belief that your action or omission was in the
          best interest of the Company.

                    (c) "DATE OF TERMINATION" shall have the meaning set forth
          in Section 3(c).

                    (d) "DISABILITY" shall be deemed to have occurred if, as a
          result of incapacity due to physical or mental illness, you shall have
          been absent from the full-time performance of your duties with the
          Company for six (6) consecutive months and, within thirty (30) days
          after written Notice of Termination by reason of disability is given
          to you, you shall not have returned to the full-time performance of
          your duties.

                    (e) "GOOD REASON" shall mean, without your express written
          consent, the occurrence after a Change in Control of the Company of
          any of the following circumstances unless, in the case of paragraphs
          (A), (C), (D), (F) or (G), such circumstances are fully corrected
          prior to the Date of Termination specified in the Notice of
          Termination given in respect thereof:

                              (A) any significant diminution in your position,
           duties, responsibilities, power, title or office as in effect
           immediately prior to a Change in Control;

                              (B) any reduction in your annual base salary as in
           effect on the date hereof or as the same may be increased from
           time to time;

                              (C) the failure by the Company to (i) continue in
          effect any material compensation or benefit plan in which you
          participate immediately prior to the Change in Control, unless an
          equitable arrangement (embodied in an ongoing substitute or
          alternative plan) has been made with respect to such plan, (ii)
          continue your participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both
          in terms of the amount of benefits provided and the level of your
          participation relative to other participants, as existed at the
          time of the Change in Control or (iii) award cash bonuses to you
          in amounts and in a manner substantially consistent with past
          practice in light of the Company's financial performance and your
          individual performance;

                              (D) the failure by the Company to continue to
          provide you with benefits substantially similar to those enjoyed
          by you under any of the Company's life insurance, medical, health
          and accident, or disability plans in which you were participating
          at the time of the Change in Control, the taking of any action by
          the Company which would directly or indirectly materially reduce
          any of such benefits, or the failure by the Company to provide
          you with the number of paid vacation days to which you are
          entitled on the basis of years of service with the Company in
          accordance with the Company's normal vacation policy in effect at
          the time of the Change in Control;

                              (E) any requirement by the Company or of any
          person in control of the Company that (i) the location at which
          you perform your principal duties for the Company be changed to a
          new location that is both outside a radius of 35 miles from your
          principal residence at the time of the Change in Control and more
          than 35 miles from the location at which you perform your
          principal duties for the Company at the time of the Change in
          Control or (ii) you travel on an overnight basis more than 90
          days in any consecutive 12-month period;

          reasonably satisfactory agreement from any successor to assume
          and agree to perform this Agreement, as contemplated in Section
          5; or

                              (G) any purported termination of your employment
          which is not effected pursuant to a Notice of Termination
          satisfying the requirements of Section 3(b), which purported
          termination shall not be effective for purposes of this
          Agreement.

                    (g) "NOTICE OF TERMINATION" shall have the meaning set forth
          in Section 3(b).

          Section 2.

     2. Term of the Agreement.
        ---------------------
  
     The term of this Agreement (the "Term") shall commence as of the date
hereof and shall continue in effect through December 31, 1999; provided,
however, that commencing on January l, 2000 and each January l thereafter, the
Term shall be automatically extended for one additional year unless, not later
than November 30 of the preceding calendar year, the Company shall have given
you written notice that the Term will not be extended; and provided further
that, if a Change in Control of the Company shall have occurred during the
original or extended Term, this Agreement shall continue in effect for a period
of not less than 24 months beyond the month in which such Change in Control
occurred.

     3. Employment Status; Termination Following Change in Control.
        ----------------------------------------------------------

          (a) No benefits shall be payable under this Agreement unless there has
been a Change in Control of the Company during the Term. You acknowledge that
this Agreement does not constitute a contract of employment or impose on the
Company any obligation to retain you as an employee. You may terminate your
employment at any time, with or without Good Reason. If your employment with the
Company terminates for any reason and subsequently a Change in Control shall
have occurred, you shall not be entitled to any benefits hereunder.

                                      -5-
<PAGE>   6

          (b) Any termination of your employment by the Company or by you
following a Change in Control of the Company during the Term shall be
communicated by written notice of termination that indicates the specific
provision in this Agreement relied upon and sets forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated ("Notice of Termination"). A Notice
of Termination shall be delivered to the other party hereto in accordance with
Section 6.

          (c) The "Date of Termination" shall mean (i) if your employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that you shall not have returned to the full-time performance of your
duties during such thirty (30) day period), and (ii) if your employment is
terminated by the Company for Cause, by you for Good Reason or for any other
reason (other than Disability), the date specified in the Notice of Termination
(which, in the case of a termination for Cause, shall not be less than thirty
(30) days from the date such Notice of Termination is given and in the case of a
termination for Good Reason shall not be less than fifteen (15) nor more than
sixty (60) days from the date such Notice of Termination is given); provided,
however, that if within fifteen (15) days after any Notice of Termination is
given, or, if later, prior to the Date of Termination (as determined without
regard to this proviso), the party receiving such Notice of Termination notifies
the other party that a dispute exists concerning the termination, then the Date
of Termination shall be the date on which the dispute is finally determined,
either by mutual written agreement of the parties, by a binding arbitration
award, or by a final judgment, order or decree of a court of competent
jurisdiction (which is not appealable or with respect to which the time for
appeal therefrom has expired and no appeal has been perfected); and provided,
further, that the Date of Termination shall be extended by a notice of dispute
only if such notice is given in good faith and the party giving such notice
pursues the resolution of such dispute with reasonable diligence.
Notwithstanding the pendency of any such dispute, the Company will continue to
pay you your full compensation in effect when the notice giving rise to the
dispute was given (including, but not limited to, base salary) and continue you
as a participant in all compensation, benefit and insurance plans in which you
were participating when the notice giving rise to the dispute was given, until
the dispute is finally resolved in accordance with this Subsection.

<PAGE>   7

          (d) You shall be entitled to the benefits provided in Section 4 if a
Change in Control shall have occurred during the Term and your employment with
the Company is subsequently terminated or terminates within 24 months after such
Change in Control, unless such termination is (A) because of your death, (B) by
the Company for Disability or Cause , or (C) by you other than for Good Reason.

          (e) Your right to terminate your employment for Good Reason shall not
be affected by your incapacity due to physical or mental illness. Your continued
employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason under this Agreement.

     4. COMPENSATION UPON TERMINATION. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

          (a) DISABILITY. During any period that you fail to perform your
full-time duties with the Company as a result of incapacity due to physical or
mental illness, you shall continue to receive base salary and all other earned
compensation at the rate in effect at the commencement of any such period
(offset by all compensation payable to you under the Company's disability plan
or program or other similar plan during such period) until your employment is
terminated by reason of Disability. Thereafter, or in the event your employment
is terminated by reason of death, your benefits shall be determined under the
Company's long-term disability, retirement, insurance and other compensation
programs then in effect in accordance with the terms of such programs.

          (b) CAUSE AND VOLUNTARY TERMINATION OTHER THAN FOR GOOD REASON. If
your employment shall be terminated by the Company for Cause or by you other
than for Good Reason following a Change in Control, the Company shall pay you
your full base salary and all other compensation through the Date of Termination
at the rate in effect at the time the Notice of Termination is given, no later
than the full fifth day following the Date of Termination, plus all other
amounts to which you are entitled under any compensation plan of the Company at
the time such payments are due, and the Company shall have no further
obligations to you under this Agreement.

                                      -7-
<PAGE>   8

          (c) TERMINATION WITHOUT CAUSE; VOLUNTARY TERMINATION FOR GOOD REASON.
If your employment with the Company is terminated by the Company (other than for
Cause, Disability or your death) or by you for Good Reason within 24 months
after a Change in Control, then you shall be entitled to the benefits below:

               (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

               (ii) the Company will pay as severance pay to you, at the time
specified in Subsection (d) below, a severance payment in an amount equal to
2.99 times the sum of (A) the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, and (B) 100% of the average annual incentive
bonus paid or payable to you by the Company for the two fiscal years ending
immediately prior to the fiscal year in which the Change of Control occurs;

               (iii) the Company shall pay to you, as incurred, to the extent
permitted by law, all legal fees and expenses reasonably incurred by you in
seeking to obtain or enforce any right or benefit provided by this Agreement;
and

               (iv) for an 18-month period after such termination, the Company
shall arrange to provide you with life, dental, and group health insurance
benefits on terms substantially similar to those applicable immediately prior to
the Notice of Termination. Notwithstanding the foregoing, the Company shall not
provide any benefit otherwise receivable by you pursuant to this paragraph (iv)
if an equivalent benefit is actually received by you from another employer
during the 18-month period following your termination, and any such benefit
actually received by you shall be reported to the Company.

                                      -8-
<PAGE>   9

          (d) The payments provided for in Subsection 4(c)(ii) shall be made in
thirty-nine (39) substantially equal bi-weekly installments over the three-year
period following the Date of Termination.

          (e) You shall not be required to mitigate the amount of any payment
provided for in this Section 4 by seeking other employment or otherwise, nor
shall the amount of any payment or benefit provided for in this Section 4 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

          (f) The Company's obligation to provide the installment payments and
benefits set forth in Subsection 4(c) are subject to your compliance in all
material respects with all agreements and covenants between you and the Company
set forth in the Employment Agreement attached hereto as EXHIBIT A, including
without limitation your agreement to refrain from (i) competing with the
Company, (ii) disclosing or using confidential or proprietary information of the
Company, or (iii) soliciting or otherwise inducing Company employees to leave
the employment of the Company.

     5. Successors; Binding Agreement.
        -----------------------------

          (a) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to terminate your employment, except that
for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Date of Termination. As used in
this Agreement, Company shall mean the Company as defined above and any
successor to its business or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
your personal or legal representatives, executors,

should die while any amount would still be payable to you hereunder if you had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to your devisee, legatee or
other designee or if there is no such designee, to your estate.

Agreement shall be governed by the laws of the State of Delaware.

                           COMPUTERVISION CORPORATION

                         Management Retention Agreement


Mr. James Hayden
11 Castle Road
Westford, MA 01886

     Computervision Corporation (the "Company") recognizes that, as is the case
with many publicly-held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may
raise among key personnel, may result in the departure or distraction of key
personnel to the detriment of the Company, its stockholders and its customers.

     The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

     In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" (as
defined below).

          Executive Officer of the Company which specifically identifies the
          manner in which the Board or Chief Executive Officer believes that you

          participate immediately prior to the Change in Control, unless an
          equitable arrangement (embodied in an ongoing substitute or
          alternative plan) has been made with respect to such plan, (ii)
          continue your participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both
          in terms of the amount of benefits provided and the level of your
          participation relative to other participants, as existed at the
          time of the Change in Control or (iii) award cash bonuses to you
          in amounts and in a manner substantially consistent with past

          principal residence at the time of the Change in Control and more
          than 35 miles from the location at which you perform your
          principal duties for the Company at the time of the Change in
          Control or (ii) you travel on an overnight basis more than 90
          days in any consecutive 12-month period;

          reasonably satisfactory agreement from any successor to assume
          and agree to perform this Agreement, as contemplated in Section
          5; or

                              (G) any purported termination of your employment
          which is not effected pursuant to a Notice of Termination

        ---------------------
  
     The term of this Agreement (the "Term") shall commence as of the date
hereof and shall continue in effect through December 31, 1999; provided,
however, that commencing on January l, 2000 and each January l thereafter, the

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

          (a) No benefits shall be payable under this Agreement unless there has

          (b) Any termination of your employment by the Company or by you
following a Change in Control of the Company during the Term shall be
communicated by written notice of termination that indicates the specific
provision in this Agreement relied upon and sets forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated ("Notice of Termination"). A Notice
of Termination shall be delivered to the other party hereto in accordance with
Section 6.

          (c) The "DATE OF TERMINATION" shall mean (i) if your employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that you shall not have returned to the full-time performance of your
duties during such thirty (30) day period), and (ii) if your employment is
terminated by the Company for Cause, by you for Good Reason or for any other
reason (other than Disability), the date specified in the Notice of Termination
(which, in the case of a termination for Cause, shall not be less than thirty
(30) days from the date such Notice of Termination is given and in the case of a
termination for Good Reason shall not be less than fifteen (15) nor more than
sixty (60) days from the date such Notice of Termination is given); provided,
however, that if within fifteen (15) days after any Notice of Termination is
given, or, if later, prior to the Date of Termination (as determined without
regard to this proviso), the party receiving such Notice of Termination notifies
the other party that a dispute exists concerning the termination, then the Date
of Termination shall be the date on which the dispute is finally determined,
either by mutual written agreement of the parties, by a binding arbitration
award, or by a final judgment, order or decree of a court of competent
jurisdiction (which is not appealable or with respect to which the time for
appeal therefrom has expired and no appeal has been perfected); and provided,
further, that the Date of Termination shall be extended by a notice of dispute
only if such notice is given in good faith and the party giving such notice
pursues the resolution of such dispute with reasonable diligence.
Notwithstanding the pendency of any such dispute, the Company will continue to
pay you your full compensation in effect when the notice giving rise to the
dispute was given (including, but not limited to, base salary) and continue you
as a participant in all compensation, benefit and insurance plans in which you
were participating when the notice giving rise to the dispute was given, until
the dispute is finally resolved in accordance with this Subsection.

          (d) You shall be entitled to the benefits provided in Section 4 if a
Change in Control shall have occurred during the Term and your employment with
the Company is subsequently terminated or terminates within 24 months after such
Change in Control, unless such termination is (A) because of your death, (B) by
the Company for Disability or Cause , or (C) by you other than for Good Reason.

          (e) Your right to terminate your employment for Good Reason shall not
be affected by your incapacity due to physical or mental illness. Your continued
employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason under this Agreement.

     4. COMPENSATION UPON TERMINATION. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

          (a) DISABILITY. During any period that you fail to perform your
full-time duties with the Company as a result of incapacity due to physical or
mental illness, you shall continue to receive base salary and all other earned
compensation at the rate in effect at the commencement of any such period
(offset by all compensation payable to you under the Company's disability plan
or program or other similar plan during such period) until your employment is
terminated by reason of Disability. Thereafter, or in the event your employment
is terminated by reason of death, your benefits shall be determined under the
Company's long-term disability, retirement, insurance and other compensation
programs then in effect in accordance with the terms of such programs.

          (b) CAUSE AND VOLUNTARY TERMINATION OTHER THAN FOR GOOD REASON. If
your employment shall be terminated by the Company for Cause or by you other
than for Good Reason following a Change in Control, the Company shall pay you
your full base salary and all other compensation through the Date of Termination
at the rate in effect at the time the Notice of Termination is given, no later
than the full fifth day following the Date of Termination, plus all other
amounts to which you are entitled under any compensation plan of the Company at
the time such payments are due, and the Company shall have no further
obligations to you under this Agreement.

          (c) TERMINATION WITHOUT CAUSE; VOLUNTARY TERMINATION FOR GOOD REASON.
If your employment with the Company is terminated by the Company (other than for
Cause, Disability or your death) or by you for Good Reason within 24 months
after a Change in Control, then you shall be entitled to the benefits below:

               (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

               (ii) the Company will pay as severance pay to you, at the time
specified in Subsection (d) below, a severance payment in an amount equal to
2.99 times the sum of (A) the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, and (B) 100% of the average annual incentive
bonus paid or payable to you by the Company for the two fiscal years ending
immediately prior to the fiscal year in which the Change of Control occurs;

               (iii) the Company shall pay to you, as incurred, to the extent
permitted by law, all legal fees and expenses reasonably incurred by you in
seeking to obtain or enforce any right or benefit provided by this Agreement;
and

               (iv) for an 18-month period after such termination, the Company
shall arrange to provide you with life, dental, and group health insurance
benefits on terms substantially similar to those applicable immediately prior to
the Notice of Termination. Notwithstanding the foregoing, the Company shall not
provide any benefit otherwise receivable by you pursuant to this paragraph (iv)
if an equivalent benefit is actually received by you from another employer
during the 18-month period following your termination, and any such benefit
actually received by you shall be reported to the Company.

                                      -8-
<PAGE>   9

          (d) The payments provided for in Subsection 4(c)(ii) shall be made in
seventy-eight (78) substantially equal bi-weekly installments over the
three-year period following the Date of Termination.

          (e) You shall not be required to mitigate the amount of any payment
provided for in this Section 4 by seeking other employment or otherwise, nor
shall the amount of any payment or benefit provided for in this Section 4 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

          (f) The Company's obligation to provide the installment payments and
benefits set forth in Subsection 4(c) are subject to your compliance in all
material respects with all agreements and covenants between you and the Company
set forth in the Employment Agreement attached hereto as Exhibit A, including
without limitation your agreement to refrain from (i) competing with the
Company, (ii) disclosing or using confidential or proprietary information of the
Company, or (iii) soliciting or otherwise inducing Company employees to leave
the employment of the Company.

indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to terminate your employment, except that
for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Date of Termination. As used in
this Agreement, Company shall mean the Company as defined above and any
successor to its business or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
your personal or legal representatives, executors,

should die while any amount would still be payable to you hereunder if you had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to your devisee, legatee or
other designee or if there is no such designee, to your estate.

Agreement shall be governed by the laws of the State of Delaware.

                                 PROMISSORY NOTE



$200,000                                                    Date:  July 16, 1996


     For value received, I, Rock S. Gnatovich, ("Maker"), promise to pay to
Computervision Corporation ("Holder"), or order, at 100 Crosby Drive, Bedford,
Massachusetts, the principal sum of Two Hundred Thousand dollars ($200,000).

     The outstanding balance of principal due hereunder may be prepaid in full
or part at any time after the date hereof, without any prepayment penalty, at
the option of Maker. So long as Maker continues to be employed in good standing
by Holder, Holder will forgive $100,000 of the principal ratably over a
four-year period at the rate of 25% of the original balance hereunder per year
commencing on the first anniversary of this Note.

     Maker agrees to pay the remaining $100,000 of the principal by the
deduction of $25,000 each year from any bonus payments due to Maker as a
participant of the Management Incentive Plan, beginning with the 1996 bonus
payout.

     The entire outstanding balance of principal advanced hereunder and other
charges as may be due hereunder, less any amount forgiven as set forth above,

Dear Doug:

You are hereby notified as of September 27, 1996 (the "Termination Date") that
your employment with Computervision Corporation (the "Company") is being
terminated. The Termination Date will be your last day worked for Computervision
as an Employee.

As you are aware, your employment with the Company and the Company's Code of
Conduct obligate you, among other things, not to disclose or use any
Confidential Company Information acquired as a result of your employment with
the Company.

Confidential Company Information includes, but is not limited to, information
which relates to the Company's past, present and future research, development
and business activities, except to the extent it is publicly known from sources
who have neither misappropriated such information nor breached any obligation of
confidentiality to the Company. Confidential Company Information does not
include your general technical skills and accumulated experience.

The Company wishes specifically to call to your attention the following classes
of Confidential Company Information with the understanding that is it by no
means an all-inclusive listing:

- - The contents, plans and schedules of the Company's future software and
hardware product ("Company Product(s)") offerings.

- - The costs, revenues and profitability of current Company Product offerings.

- - The contents of the Company's business plans, including, without limitation,
strategic and operating plans.

- - The design, attributes, features, and technical details of Company Products.

- - Your knowledge of the Company's customers and suppliers, its customer and
supplier relationships, the Company Products being used by those customers, and
the supplier products being purchased by the Company.

- - Personnel plans, data and information including, without limitation, employee
lists, unique skills sets, knowledge, experience and salaries.

<PAGE>   6

- - Inventions, discoveries, methods, processes and data, both technical and
non-technical.

- - Plans, programs, dealings and relationships between the Company and its
various third party distribution channels.

Should you have any questions concerning whether the Company regards certain
information as confidential or whether your actions violate the Code of Conduct,
you should contact Anthony N. Fiore, Jr., Vice President and General Counsel, at
617/275-1800, extension 5073.

You hereby acknowledge and agree that:

a.   You have had access to Confidential Company Information.

b    The Company regards such information as confidential.

c.   You will not disclose or make use of any such Confidential Company
     Information without express written authorization from the Company

d.   You will conduct your affairs in such a manner so that they are not
     detrimental to the interest of the Company, its products or employees.

e.   Upon separation from the Company, you will return to the Company all
     Confidential Company Information in your possession and will not retain any
     copies.

In addition, in your employment agreement with the Company, you agreed not to
solicit or employ Company employees and not to engage in certain activities
competitive with the Company's business for one year after termination of your
employment. While we naturally assume that you will honor your obligations, we
wanted to remind you so that you will understand the Company's position on the
matter. Hopefully, this will help us both avoid any unpleasantness that may
arise from oversight on your part or failure to appreciate the seriousness with
which the Company will view any breach of your obligations.

The terms and conditions of your separation are as follows:

1.   Your accrued and unused vacation credit as of the Termination Date will be
     paid in a lump sum with your paycheck on or immediately after the
     Termination Date. You will receive your final direct paycheck on October 4,
     1996 payable through September 27, 1996.

2.   Beginning September 30, 1996 for a two-year period, you will be retained by
     the Company as a Consultant.

     Your assignment and duties will be directed by either Russell Planitzer,
     Kathleen Cote or Barry Cohen.

<PAGE>   7

     You will be paid as follows:

     o    a $25,000.00 Consultant fee for the twelve months beginning September
          30, 1996 through September 30, 1997 payable at the beginning of each
          quarter.
     o    a $25,000.00 Consultant fee for the twelve months beginning October 1,
          1997 through September 30, 1998 payable at the beginning of each
          quarter.
     o    a $200,000.00 Special Bonus for your work associated with OSS. This is
          separate and apart from your eligibility in the Computervision
          Management Incentive Bonus Plan as outlined in Section 8. This payment
          will also be made at the beginning of each quarter beginning September
          30, 1996 through September 30, 1997.

     As is our standard practice with all individually-retained consultants, you
     will be required to execute a standard consultant agreement which is
     attached. Additionally, you will be eligible to obtain consulting
     opportunities with companies other than Computervision as long as these
     assignments are not in conflict or in the competitive arena in which
     Computervision operates.

     As of July 27, 1996, the day you moved out of your apartment in Boston.
     Computervision will reimburse you for all reasonable and customary travel
     and living expenses including a rental car incurred as an employee.

     You will be required to submit a quarterly invoice prior to the beginning
     of the quarter to include your monthly retainer and any normal or customary
     business expenses, along with supported receipts for payment.

3.   If you wish to continue your medical and dental coverage beyond the
     Termination Date, you may do so for an additional 18 months pursuant to
     your rights under the Consolidated Omnibus Budget Reconciliation Act
     (COBRA) or until you become eligible for coverage under another plan,
     whichever is earlier. If you elect to continue coverage beyond your
     Termination Date, you will be responsible for paying the full cost of
     coverage.

4.   Effective as of the Termination Date, your participation in the Company
     Capital Accumulation Plan ("CAP") will cease. As a Consultant you will not
     be eligible to participate/contribute to the Plan further not will you
     receive a match for 1996.

     Your fund balances will be prepared for distribution within eight (8) weeks
     following the end of the month in which termination occurs. However, plan
     distributions after January 1, 1993 are considered taxable and will be
     subject to an automatic twenty (20) percent withholding tax unless you
     direct State Street Bank and Trust ("Plan Administrator") to make the
     distribution check payable directly to an Individual Retirement Arrangement
     ("IRA") or other qualified retirement plan. Any distribution check payable
     directly to you will require the Plan Administrator to withhold twenty (20)
     percent of the distribution as taxes. The withholding is required even if
     you roll over the distribution into an IRA or other qualified plan within
     the requisite sixty (60) day period.

     The Plan Administrator will be prepared to issue your distribution check
     payable either to you or your IRA or other qualified retirement plan upon
     your request. At the time your funds are to be distributed, the Plan
     Administrator will advise you of the options available and provide you with
     the appropriate form to execute your choice. If the total amount

<PAGE>   8

     of your account exceeds $3,500, you may leave the funds in the CAP Plan
     permanently or until you have made a distribution choice. Funds left in the
     CAP Plan would remain subject to the Cap Plan provisions.

5.   On February 19,1996 the Compensation Committee voted to modify the vesting
     of your options that would have vested in 1999 and 2000 to vest in 1997 and
     1998 respectively. Additionally, Computervision has agreed to establish a
     Consulting Agreement with you as set forth by the attached agreement.

6.   In consideration of the provisions of Paragraph 5, the adequacy of which
     you hereby acknowledge, you hereby fully, forever, irrevocably and
     unconditionally release, remise and discharge the Company, its officers,
     directors, stockholders, agents and employees from any and all claims,
     charges, complaints, demands, actions, causes of action, suits, rights,
     debts, sums of money, costs, accounts, reckonings, covenants, contracts,
     agreements, promises, doings, omissions, damages, executions, obligations,
     liabilities, and expenses (including attorneys' fees and costs), of every

                       FIRST AMENDMENT TO CREDIT AGREEMENT

financial institutions listed on the signature pages hereto, Bankers Trust
Company, as Agent and Fleet Bank of Massachusetts, N.A., as Co-Agent under the

Credit Agreement referred to below.

                              W I T N E S S E T H :

     WHEREAS, the Borrower, various lending institutions (the "Banks") , and

     WHEREAS, the parties hereto wish to amend the Credit Agreement as herein
provided;

     NOW, THEREFORE, it is agreed:

     1. Section 1.10(c) is hereby amended by deleting such Section in its
entirety and inserting in lieu thereof a new Section to read as follows:

          "(c) If any Bank shall have determined that after the date hereof, the
     adoption or effectiveness of any applicable law, rule or regulation
     regarding capital adequacy, or any change therein, or any change in the
     interpretation or administration thereof by any governmental authority,
     central bank or comparable agency charged with the interpretation or
     administration thereof, or compliance by such Bank or its parent
     corporation with any request or directive regarding capital adequacy
     (whether or not having the force of law) of any such authority, central
     bank or comparable agency, has or would have the effect of reducing the
     rate of return on such Bank's or its parent corporation's capital or assets

<PAGE>   2

     level below that which such Bank or its parent corporation could have

     by such Bank (with a copy to the Agent), accompanied by the notice referred
     to in the last sentence of this clause (c), the Borrower shall pay to such
     Bank such additional amount or amounts as will compensate such Bank or its
     parent corporation for such reduction. Each Bank, upon determining in good
     faith that any additional amounts will be payable pursuant to this Section
     1.10(c), will give prompt written notice thereof to the Borrower, which
     notice shall set forth the basis of the calculation of such additional
     amounts, although the failure to give any such notice shall not release or
     diminish the Borrower's obligations to pay additional amounts pursuant to
     this Section 1.10(c) upon the subsequent receipt of such notice."

in its entirety and inserting in lieu thereof as a new ANNEX I thereto, the
ANNEX I attached hereto. Each Bank hereby acknowledges and agrees that from and

such amount may be reduced from time to time in accordance with the terms of the
Credit Agreement.

     3. ANNEX II to the Credit Agreement is hereby amended by deleting the same
in its entirety and inserting in lieu thereof as a new ANNEX II thereto, the
ANNEX II attached hereto.

line item "Capitalized Leases...$11,284,000" immediately following the line item
"CV Corporation owes CV UK/CV R&D (netted balance)...$13,735,744".

     5. The Amendments to the Subsidiary Guaranty, the Security Agreement and
the Pledge Agreement substantially in the forms attached hereto as Annexes III,

contained in the Credit Agreement as though made on the Amendment Effective
Date, unless stated to relate to a specific earlier date, in which case such
representations and warranties shall be true and correct in all material
respects as of such earlier date and 


<PAGE>   3

(ii) represents and warrants that there exists no Default or Event of Default,
in each case on the Amendment Effective Date (as hereinafter defined), both

modification, acceptance or waiver of any other provision of the Credit
Agreement.

     8. This Amendment may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, each of which counterparts
when executed and delivered shall be an original, but all of which shall
together constitute one and the same instrument. A complete set of counterparts
shall be lodged with the Borrower and the Agent.

     9. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF

counterpart hereof (whether the same or different counterparts) and shall have
delivered the same to the Agent at its New York Office and (ii) the Borrower

     11.  Section 10 of the Credit Agreement shall be amended by inserting the
following new definition in appropriate alphabetical order:

          "Borrowing Base" shall have the meaning provided in the Borrowing Base
     Amendment.

          "Borrowing Base Amendment" shall be an amendment to this Credit
     Agreement executed by the Borrower and the Required Banks, which inter
     alia, shall define the Borrowing Base on a mutually agreeable basis.

          "Borrowing Base Amendment Date" shall mean the date on which the
     Borrowing Base Amendment becomes effective in accordance with its terms, it
     being understood that one condition to such effectiveness shall be the
     delivery of a Borrowing Base Certificate dated as of such effective date.

          "Borrowing Base Certificate" shall have the meaning provided in the
     Borrowing Base Amendment.

     12.  Section 10 of the Credit Agreement shall be further amended by 
deleting the period at the end of the definition of "Consolidated EBITDA" and
inserting the following clause in lieu thereof:

     "and adjusted by adding, (i) $19,500,000, for the Test Period ending
     December 31, 1996; (ii) $26,500,000, for the Test Period ending March 31,
     1997; (iii) $26,500,000, for the Test Period ending June 30, 1997; (iv)

<PAGE>   6

     $26,500,000, for the Test Period ending September 30, 1997; and (v)
     $7,000,000, for the Test Period ending December 31, 1997."

     13.  The Borrower hereby agrees to pay to the Agent for distribution to 
each Bank which executes this Amendment, a fee equal to 1/8 of 1% of the
aggregate Commitment of such Bank immediately prior to the Amendment Effective
Date.

     14.  The Borrower hereby agrees to cooperate in good faith with the Agent
and the Banks with the intention of formulating the definition of Borrowing Base
and having the Borrowing Base Amendment Date occur as soon as reasonably
practical after April 1, 1997. The Borrower hereby agrees to continue to file a
quarterly information statement of Form 10-Q every fiscal quarter and each such
Form 10-Q shall have attached as an exhibit an auditor's review report (which
shall not include any exceptions). Until the Borrowing Base Amendment Date, an
Event of Default will result from the failure of the Borrower to file a form
10-Q complying with the requirements of the preceding sentence. An Event of
Default will exist if the Borrowing Base Amendment Date has not occurred on or
prior to April 1, 1998.

     15.  In order to induce the Banks to enter into this Amendment, the 
Borrower hereby (i) makes each of the representations, warranties and agreements
contained in the Credit Agreement as though made on the Amendment Effective
Date, unless stated to relate to a specific earlier date, in which case such
representations and warranties shall be true and correct in all material
respects as of such earlier date and (ii) represents and warrants that there
exists no Default or Event of Default, in each case on the Amendment Effective
Date (as hereinafter defined), after giving effect to this Amendment.

     16.  This Amendment is limited as specified and shall not constitute a
modification, acceptance or waiver of any other provision of the Credit
Agreement.

     17.  This Amendment may be executed in any number of counterparts and by 
the different parties hereto on separate counterparts, each of which
counterparts when executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A complete set of
counterparts shall be lodged with the Borrower and the Agent.

     18.  THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF
NEW YORK.




                                       6

     19.  This amendment shall become effective on the date (the "Amendment
Effective Date") when the Borrower and the Required Banks shall have signed a
counterpart hereof (whether the same or different counterparts) and shall have
delivered (including by way of facsimile transmission) the same to the Agent.

     20.  From and after the Amendment Effective Date, all references in the
Credit Agreement and each of the other Credit Documents shall be deemed to be
references to the Credit Agreement as modified hereby.
