the business and operations which comprise the Company as of the date hereof.
The following terms used in this Prospectus have the respective meanings

manufacturing; (iii) CAE--computer-aided engineering; (iv) MCAD--the mechanical
CAD/CAM/CAE business; (v) PDM--product data management; and (vi) seat--a

                                  THE COMPANY
 
  The Company is a leading global provider of scalable, integrated, enterprise-
level MCAD solutions that are used for virtual product development principally
in the automotive and transportation, aerospace, consumer products, equipment
and machinery and electronics industries. The Company's MCAD solutions consist
of both software products and consulting services. The Company's software
products allow customers to reduce design, engineering and manufacturing costs
and minimize the time between a product's inception and its introduction to the
market while simultaneously improving product quality. Through MCAD, product
design is accomplished digitally, eliminating the need for paper drawings or
physical prototypes. With digital assemblies, fit, tolerances and moving
mechanisms, as well as design alternatives, can be tested before a physical
product has been made. For example, automobile designers can virtually "open"
the door or trunk and can "walk around" a digital three-dimensional ("3-D")
model of a car to assess its design. MCAD systems produce large volumes of data
which can be managed by the Company's product data management ("PDM") software.
The Company's PDM software makes the most current product data readily
accessible to all appropriate users throughout a manufacturing enterprise. Some
of the Company's significant customers, located worldwide, include General
Motors Corporation ("GM"), The Boeing Company ("Boeing"), Denso Co., Ltd.
("Denso") and General Electric Company ("GE").
 
  The Company offers a full line of design, analysis and manufacturing software
products that meets the diverse needs of its customer base, which includes a
spectrum of companies from multinational corporations to small machine shops.
The Company addresses all aspects of digital product development, including (i)
product modeling, (ii) product information management, (iii) data transfer and
(iv) process re-engineering. The Company's integrated, scalable software
solutions range from Unigraphics, its high-end MCAD software product suite for
complex design, manufacture and assembly projects, to Solid Edge, its Windows-
based, easy-to-use design and drafting product. Both Unigraphics and the latest
version of Solid Edge, Version 5.0 (which is expected to be released in May
1998), are based on the Company's core solid modeling kernel, Parasolid. As a
result, the Company can differentiate itself from its competitors by enabling
Unigraphics and Solid Edge to seamlessly share geometric data without the need
for translation. The Company's PDM software, IMAN, works in conjunction with
both the Company's and third parties' MCAD software to organize and manage the
large volume of data and numerous versions associated with the typical digital
product model. A key element of the Company's product development strategy is
the management, visualization and simulation of product data across the World
Wide Web ("Web") so that model data may be shared among all users of the
Company's MCAD and PDM products and companion applications. In addition, the
Company offers a full range of customization, implementation and integration
consulting services that enables customers to re-engineer their methods of
virtual product development by optimizing the use of the Company's software.
 
  Through its Unigraphics, Solid Edge, Parasolid and IMAN products, the Company
served more than 4,000 customers worldwide at December 31, 1997, comprising an
aggregate of over 93,000 seats. Of these seats, there were over 49,000
Unigraphics seats, over 9,000 Solid Edge seats, over 72,000 Parasolid seats
(including over
 
                                       4
<PAGE>
 
49,000 seats embedded in Unigraphics) and over 12,000 IMAN seats. With its
suite of core products, its large worldwide installed seat base and the
continuing evolution of Parasolid as a solid modeling standard for MCAD
software, the Company believes that it is well positioned to take advantage of
the MCAD market's varying demands for software functionality, virtual product
development and product data management.
 
BUSINESS STRATEGY
 
  Demand in MCAD and PDM markets is dictated by the needs of users throughout
companies of all sizes and across extended enterprises to collaborate on
virtual product development. These users often require different levels of
software functionality. The Company's strategy is to offer a variable,
customizable combination of software products and implementation and
integration services to address the product and process complexities associated
with design and assembly projects. The key elements of the Company's strategy
include:
 
  PROVIDING A FULL RANGE OF INTEGRATED SCALABLE ENTERPRISE SOLUTIONS. The
Company provides a full range of MCAD software products to meet the needs of
its customers, from its high-end Unigraphics product suite to its mid-range
offering, Solid Edge. Upon the release of Solid Edge 5.0, both it and
Unigraphics will be integrated through the use of the Company's core solid
modeler, Parasolid, thereby allowing Unigraphics and Solid Edge to seamlessly
share geometric data without the need for translation. Unigraphics is scalable
with the ability to add modules or features to fit the needs of the Company's
customers, thereby reducing hardware system requirements. Solid Edge's Windows
capabilities improve design engineering productivity, shorten learning curves
and reduce training costs. The Company believes that it is well positioned
because each of its customers can buy the precise software product or products
that meet that customer's particular needs and allow its users to share data
within a single organization or throughout several organizations.
 
  ESTABLISHING PARASOLID AS A SOLID MODELING STANDARD. The Company believes
that Parasolid has emerged as the mid-range MCAD solid modeling standard while
being fully capable of addressing the demanding requirements of high-end MCAD
software. Unigraphics, the Company's high-end MCAD offering, is based on
Parasolid. The Company licenses Parasolid for incorporation into mid-range MCAD
software products such as Dassault Systemes S.A.'s ("Dassault") Solid Works and
Parametric Technology Corporation's ("Parametric") DesignWave. In addition,
Bentley Systems, Inc. ("Bentley") has recently converted its mid-range product,
MicroStation Modeler, to Parasolid. The Company also licenses Parasolid to
various third-party niche software application developers, who create
Parasolid-compatible specialized applications that enhance the functionality of
Unigraphics and Solid Edge. Accordingly, the Company expects that the growing
prevalence of Parasolid-based applications will make Parasolid part of the
buying criteria for MCAD software, thereby giving Unigraphics, the only high-
end MCAD product to use Parasolid, an advantage over competing high-end
products.
 
  OFFERING FULL FUNCTION PRODUCT DATA MANAGEMENT. The Company believes that
IMAN is one of the industry's most functional product data management tools for
engineering applications. IMAN captures, manages and provides enterprise-wide
access to the large volume of data generated throughout the virtual product
development cycle. IMAN's technology is scalable for use within a wide range of
customer implementations, extending from small Unigraphics-centric design teams
to globally distributed enterprises with thousands of concurrent users across
many functional areas, such as engineering, manufacturing, marketing and
procurement. The Company believes that IMAN's strengths lie in (i) its tight
integration with Unigraphics, which enables IMAN to manage the complex
interrelationships among Unigraphics files, (ii) its variant configuration
modeling, which facilitates the definition of the modularized, rules-based
views of the bill of materials that are required for efficient manufacturing of
customized products and (iii) its object-oriented architecture, which enables
designers to share data across an enterprise. A key element of the Company's
PDM strategy is utilizing Web-based technologies to provide a common framework
for the visualization, simulation and management of product data. The Company's
Web technologies provide enterprise-wide access to the virtual product model
and associated specification data, enabling organizations outside of the
traditional users of the Company's MCAD products to utilize the data. For
example, marketing departments can view virtual products and provide immediate
feedback during the product development process.

  MAINTAINING TECHNOLOGICAL LEADERSHIP. The Company is focused on continually
developing and acquiring the most technologically advanced MCAD products.
Unigraphics' breadth of modeling functionality combines complex surface design
capabilities with advanced feature and solid modeling while providing some of
the most advanced CAM technology on the market today. Solid Edge, which has
pioneered advances in ease of use, was developed with native Windows
functionality, including familiar "drag and drop" features, menu driven
options, dialog boxes and on-line help, and was the first mechanical CAD
product to be certified as Microsoft Office compatible. In order to maintain
its technological leadership, the Company releases major enhancements
containing significant improvements to each of its four core products
approximately twice per year. In addition, the Company has developed UG/WAVE, a
next generation parametric approach to top-down product design that allows
"what-if" evaluations of engineering alternatives. For example, UG/WAVE allows
engineers to more efficiently evaluate at the system level the impact of
changes in wing design on the aerodynamic performance of an airplane.
 
  LEVERAGING AND EXPANDING ITS CUSTOMER BASE. The Company intends to expand its
user base by increasing sales to existing customers and to new customers by
expanding its sales force and by utilizing Web-based distribution. The Company
intends to increase the licensing of its MCAD software to its existing customer
base by offering an affordable integrated scalable product line. The Company is
targeting existing users of two-dimensional ("2-D") software by marketing the
latest version of Solid Edge as an affordable, easy-to-use 3-D product. The
Company intends to increase the size of its customer base by marketing to the
suppliers of its aerospace and automotive original equipment manufacturers
("OEMs"). The Company believes that both of its MCAD software offerings are
attractive to suppliers who seek to meet OEM requirements because (i)
Unigraphics is available in discrete modules to allow users to purchase only
the Unigraphics capabilities their businesses require and (ii) Solid Edge is an
affordable easy-to-use MCAD software package that will have the ability to
seamlessly transfer geometric data to high-end Unigraphics users. As part of
the Solid Edge Acquisition (as hereinafter defined), the Company acquired
Engineering Modeling Systems Software ("EMS"), a high-end MCAD product, which
had over 6,000 seats at December 31, 1997. The Company will seek to convert EMS
customers to Unigraphics or Solid Edge.
 
RECENT DEVELOPMENTS
 
  SOLID EDGE ACQUISITION. On March 2, 1998, the Company completed the
acquisition (the "Solid Edge Acquisition") of the MCAD business of Intergraph
Corporation ("Intergraph") consisting of the Solid Edge and EMS product lines
(the "Solid Edge/EMS Business") for a purchase price of $105 million (excluding
approximately $2 million of acquisition costs). The transfer of certain non-
U.S. assets and personnel of the Solid Edge/EMS Business is expected to be
completed on or about March 31, 1998, subject to receipt of relevant foreign
government approvals. The Solid Edge Acquisition involved the direct transfer
to the Company of the intellectual property rights (through the ownership of
some intellectual property and a perpetual, royalty-free license for the
remaining intellectual property) needed to modify and improve all acquired or
licensed intellectual property and to own any modifications or improvements
that it makes. Beginning with Version 5.0, the Company will replace Solid
Edge's existing core modeler with Parasolid. Intergraph will continue to
distribute Version 4.0 of Solid Edge (at no cost to the Company and with all
proceeds for the benefit of the Company) in order to comply with the terms of
Intergraph's license for the existing solid modeling kernel in Version 4.0 of
Solid Edge. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Solid Edge Acquisition."
 
  Generally, Intergraph's customer contracts for Solid Edge and EMS also
covered other products and services of Intergraph. Therefore, such contracts
were not assigned to the Company. However, the Company will provide products
and services under such contracts as they relate to the Solid Edge/EMS
Business, and will receive the related economic benefits, until such time as
the Company and those Solid Edge and EMS customers enter into new agreements.

  RELATIONSHIP WITH EDS. The Company is a newly-formed Delaware corporation
and, prior to the Offering (as hereinafter defined), a direct wholly owned
subsidiary of Electronic Data Systems Corporation ("EDS"). Upon completion of
the Offering, EDS will own 100% of the outstanding Class B Common Stock, par
value $.01 per share (the "Class B Common Stock"), of the Company representing
approximately  % of the combined voting power of all classes of voting stock of
the Company (approximately  % if the U.S. Underwriters' over-allotment option
is exercised in full). As long as EDS beneficially owns a majority of the
combined voting power, it will have the ability to elect all of the members of
the Board of Directors of the Company (the "Board of Directors") and ultimately
to control the management and affairs of the Company. See "Risk Factors--
Relationship with EDS."
 
  Pursuant to a reorganization consummated effective as of January 1, 1998 (the
"Reorganization"), the Company became the successor to the MCAD businesses of
EDS which were formerly operated within several business units of EDS. In order
to fund the purchase price and expenses in connection with the Solid Edge
Acquisition, the Company borrowed $107 million from EDS pursuant to the
Intercompany Credit Agreement (as hereinafter defined). In addition, effective
March 6, 1998, the Company issued to EDS as a dividend a $73 million note (the
"Intercompany Note"). In connection with the Reorganization, the Company
entered into certain agreements with EDS and its affiliates, the terms of which
were generally effective as of January 1, 1998. See "Risk Factors--Relationship
with EDS," "Relationship with EDS and Certain Transactions--Contractual
Arrangements" and "Pro Forma Financial Information."

                                 RISK FACTORS
 
  Prospective purchasers of the Class A Common Stock offered hereby should
consider carefully the following risk factors in addition to the other
information presented in this Prospectus.
 
RISKS ASSOCIATED WITH ABSENCE OF HISTORY AS A STAND-ALONE COMPANY AND
INTEGRATION OF SOLID EDGE/EMS BUSINESS
 
  The Company, which was formed in October 1997, succeeded to the MCAD
business of EDS in the United States effective as of January 1, 1998 (or later
with respect to certain operations outside the United States). Prior to such
time, the operations of the Company had been operated within several business
units of EDS, and not as a separate legal division or subsidiary. After the
Reorganization, the Company integrated its various operations into a single
operating unit. Although management has extensive experience managing the
Company as a part of EDS, there is no operating history of the Company as a
stand-alone entity for a prospective investor to evaluate. There can be no
assurance that the Company will be able to successfully integrate its
operations into a single entity or that such integration will be achieved in
an efficient and effective manner. After the Offering, the Company will be a
subsidiary of EDS, but will operate as a stand-alone company, and EDS will
have no obligation to provide assistance to the Company or any of its
subsidiaries except for certain financial, tax and other services as described
in "Relationship with EDS and Certain Transactions."
 
  The Company consummated the Solid Edge Acquisition on March 2, 1998,
although the transfer of certain assets located outside the United States is
expected to occur on or about March 31, 1998, subject to the receipt of
relevant governmental approvals. Prior to the Solid Edge Acquisition, the
Solid Edge/EMS Business had not been operated as a separate subsidiary or
division of Intergraph but had been integrated with Intergraph's other
operations. As a result, there is only limited financial and operating
information for an investor to evaluate.
 
  Since the version of Solid Edge available at the time of the Solid Edge
Acquisition incorporates the core modeling kernel of another company, the
Company and Intergraph have agreed that Intergraph will make all license sales
of Solid Edge and remit the proceeds thereof to the Company until the Company
releases Solid Edge 5.0 (expected in May 1998), which will contain the
Company's Parasolid solid modeling kernel. Management and operation of the
Solid Edge/EMS Business will initially require a certain amount of
coordination with Intergraph and must be integrated with the Company's other
businesses and there can be no assurance that any such coordination or
integration will be achieved in an efficient and effective manner. The Company
continues to seek additional opportunities to acquire, or merge with, related
businesses and is presently evaluating, as it does on a regular basis,
potential opportunities. The Company is not currently engaged in negotiations
for a material acquisition. There can be no assurance that the Company will be
able to successfully integrate the Solid Edge/EMS Business or such other
businesses into its operations or that the integration of the Solid Edge/EMS
Business or any other acquired businesses will not materially limit the amount
of time that management may devote to running the Company's day-to-day
business or disrupt the Company's ongoing business. Further growth in the
Company's operations from additional businesses may strain the Company's
existing management resources and its financial and management systems and
controls and may require the Company to make additional expenditures in such
areas. See "Prospectus Summary--Recent Developments--Solid Edge Acquisition"
and "Management's Discussion and Analysis of Financial Condition and Results
of Operations."
 
RELATIONSHIP WITH EDS
 
  EDS currently owns all of the outstanding capital stock of the Company. See
"Relationship with EDS and Certain Transactions." Upon completion of the
Offering, EDS will own 100% of the Company's outstanding Class B Common Stock,
representing approximately  % of the combined voting power of all classes of
voting stock of the Company (approximately   % if the U.S. Underwriters' over-
allotment option is exercised in full). The Class A Common Stock and the Class
B Common Stock will be the only voting stock of the Company
 
                                      11
<PAGE>
 
outstanding following the Offering. As long as EDS continues to beneficially
own a majority of the combined voting power of the Common Stock, it will have
the ability to elect all of the members of the Board of Directors and control
the management and affairs of the Company, including any determinations with
respect to mergers or other business combinations involving the Company, the
acquisition or disposition of assets by the Company, the incurrence of
indebtedness by the Company, the issuance of any additional Common Stock or
other equity securities or the declaration and payment of any dividends on the
Common Stock. In addition, EDS will be able to determine the outcome of any
matter submitted to a vote of the Company's stockholders for approval and to
cause or prevent a change in control of the Company.
 
  The Restated Certificate of Incorporation of the Company (the "Certificate
of Incorporation") provides that any amendment or termination of any agreement
or arrangement, or any new agreement or arrangement, between the Company and
EDS or its affiliates effected with the approval of a majority of the
Company's directors who are not officers of either the Company or EDS or
directors of EDS (the "Disinterested Directors") or consistent with guidelines
or standards approved by the Disinterested Directors, or approved by the
holders of a majority of the Company's outstanding voting stock (not including
shares owned by EDS) shall be deemed fair to the Company and its stockholders.
If such approval is not obtained, however, no presumption shall arise that
such amendment or termination (or new agreement) is not fair to the Company
and its stockholders. The Certificate of Incorporation also contains
provisions allocating corporate opportunities that may be suitable for both
EDS and the Company. See "Description of Capital Stock--Certificate of
Incorporation and Bylaw Provisions."
 
  Certain intercompany agreements and arrangements exist between the Company,
EDS and EDS' other subsidiaries, including a management services agreement and
a subcontract arrangement with respect to the provision of Unigraphics and
related services to GM. There can be no assurance that the services provided
to the Company by EDS under the Affiliate Agreements (as hereinafter defined)
will continue to be provided, and if not, whether or on what terms such
licenses or services could be replicated. In addition, while the parties to
the Affiliate Agreements endeavored to establish terms fair to both EDS and
the Company, as a result of EDS' control of the Company none of such
agreements resulted from "arm's-length" negotiations. There can be no
assurance that the Company would not have received more favorable terms from
an unaffiliated party. For a description of the Affiliate Agreements, see
"Relationship with EDS and Certain Transactions."
 
  Conflicts of interest may arise between the Company and EDS in a number of
areas relating to their past and ongoing relationships, including the nature
and quality of services rendered by EDS and its affiliates to the Company, the
performance by the Company of its obligation under the subcontract arrangement
relating to products and services to be provided to GM, potential competitive
business activities, tax and employee benefit matters, indemnity agreements,
registration rights, sales or distributions by EDS of all or any portion of
its ownership interest in the Company or EDS' ability to control the
management and affairs of the Company. There can be no assurance that EDS and
the Company will be able to resolve any potential conflict or that, if
resolved, the Company would not have received more favorable resolution if it
were dealing with an unaffiliated party. In addition, certain of the Affiliate
Agreements contain specific procedures for resolving disputes between the
Company and EDS with respect to the subject matter of those agreements. There
can be no assurance that more favorable results to the Company would not be
obtained under different procedures.
 
  Beneficial ownership of at least 80% of the total voting power and value of
the outstanding Common Stock is required in order for EDS to continue to
include the Company in its consolidated group for federal income tax purposes,
and beneficial ownership of at least 80% of the total voting power and 80% of
each class of nonvoting capital stock is required in order for EDS to effect a
tax-free spin-off (as defined under "Description of Capital Stock--Common
Stock--Conversion") of the Company or certain other tax-free transactions.
Each member of a consolidated group for federal income tax purposes is jointly
and severally liable for the federal income tax liability of each other member
of the consolidated group. Each member of the EDS controlled group, which
includes EDS, the Company and EDS' other subsidiaries, is also jointly and
severally liable for pension and benefit funding and termination liabilities
of other group members, as well as certain benefit plan taxes. Accordingly,
the Company could be liable under such provisions in the event any such
liability is incurred, and
 
                                      12
<PAGE>
 
not discharged, by any other member of the EDS consolidated or controlled
group. If the Company were no longer to be included in EDS' consolidated group
for federal tax purposes, there is no assurance that the Company's tax
position would not be less favorable than it is at present.
 
  In addition, by virtue of its controlling beneficial ownership and the terms
of a Tax Sharing Agreement (as hereinafter defined) between the Company and
EDS, EDS effectively controls all of the Company's tax decisions. Under the
Tax Sharing Agreement, EDS has sole authority to respond to and conduct all
tax proceedings (including tax audits) relating to the Company's federal and
combined state returns, to file all such returns on behalf of the Company and
to determine the amount of the Company's liability to (or entitlement to
payment from) EDS under the Tax Sharing Agreement. See "Relationship with EDS
and Certain Transactions--Contractual Agreements--Tax Sharing Agreement." This
arrangement may result in conflicts of interests between the Company and EDS.
For example, under the Tax Sharing Agreement, EDS may choose to contest,
compromise or settle any adjustment or deficiency proposed by the relevant
taxing authority in a manner that may be beneficial to EDS and detrimental to
the Company.
 
DEPENDENCE ON KEY CUSTOMERS/INDUSTRIES
 
  The Company's earnings are highly dependent on its business with GM. In
connection with the split-off of EDS from GM in June 1996, EDS entered into a
Master Services Agreement (the "EDS/GM MSA") and certain related agreements
pursuant to which EDS serves as GM's principal supplier of information
technology on a worldwide basis for an initial term of 10 years. The EDS/GM
MSA serves as the framework for the negotiation and operation of service
agreements between GM and EDS related to certain "in scope" services (as
defined in the EDS/GM MSA). The EDS/GM MSA provides GM with termination rights
under certain circumstances, including upon the occurrence of certain changes
of control of EDS. EDS and GM entered into a Unigraphics Software Corporate
License Agreement, effective as of July 1, 1996 (the "EDS/GM Site License
Agreement"), which provided for the sale to GM of a perpetual license of up to
10,000 seats of Unigraphics, including IMAN, and the provision of three years
of maintenance services for such products. These products and services are "in
scope" services under the EDS/GM MSA. The EDS/GM Site License Agreement
terminates on June 30, 1999. In connection with the Reorganization, EDS and
the Company entered into a Memorandum of Understanding, effective January 1,
1998 (the "GM Subcontract"), pursuant to which the Company receives all
revenues and performs EDS' obligations under the EDS/GM Site License Agreement
and agrees to cooperate with EDS in providing additional products and services
to GM under the EDS/GM MSA. The GM Subcontract further provides that the
Company may provide directly to GM products and services that are outside of
the scope of the EDS/GM MSA. Approximately 34%, or $139.4 million, of the
Company's 1996 revenue was attributable to products and services provided to
GM. Although less than 10% of the Company's 1997 revenue was attributable to
the products and services provided to GM, approximately 48% of the Company's
accounts receivable balance at December 31, 1997 was related to products and
services provided to GM. If the EDS/GM MSA were to be terminated, or if the
Company (as a subcontractor to EDS) and GM do not enter into a successor to
the EDS/GM Site License Agreement upon termination of that agreement in 1999,
the Company's financial condition and results of operations would be
materially adversely affected.
 
  The Company's products are licensed to customers in a variety of industry
sectors, but approximately 60% of the Company's 1997 revenue was derived from
the automotive and transportation and aerospace industries. Both industries
are relatively mature MCAD markets that have been substantially penetrated.
The Company's future success will depend on its ability to maintain and
increase product licensing in the automotive and transportation and aerospace
industries, as well as other industries, and there can be no assurance that
the Company will be able to achieve this objective. Additionally, both the
automotive and transportation and aerospace industries are cyclical, and an
economic downturn in one of these industries would likely have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Customers."
 
                                      13
<PAGE>
 
RAPID TECHNOLOGICAL CHANGE; NEW PRODUCTS
 
  The MCAD industry is characterized by rapidly changing technology and
frequent new product introductions and product enhancements. Therefore, the
Company's success is highly dependent upon its ability to enhance its existing
products and to introduce new products in a cost-effective and timely manner
to meet evolving customer requirements. The Company has committed and intends
to continue to commit substantial resources to the development of new
products. Because new product development commitments must be made well in
advance of sales, however, new product decisions must anticipate both future
demand and the technology that will be responsive to such demand. Delays in
developing new products with anticipated technological advances or in
commencing releases of new products may have a material adverse effect on the
Company's financial condition and results of operations, as might the issuance
of releases in which material defects or shortcomings emerge. There can be no
assurance that new products will gain market acceptance or will not be
adversely affected by technological changes or new product announcements by
others. In addition, since many software users rely on databases of existing
parts for new product designs, there can be no assurance that potential
customers will switch to the Company's new products.
 
  The Company intends to introduce a number of new product innovations in the
first half of 1998. The Company will introduce its Parasolid solid modeling
kernel in Solid Edge 5.0 (expected in May 1998), replacing Solid Edge's
current solid modeling kernel. New versions of Unigraphics contain significant
changes in the software with the introduction of the UG/WAVE technology. There
can be no assurance that future versions of Unigraphics and Solid Edge or any
of the Company's other core products will perform as expected or that they
will achieve market acceptance or contribute significantly to the Company's
revenue. The Company's business strategy includes establishing Parasolid as
the MCAD industry's solid modeling standard. Competitors of the Company could
develop independent solid modeling kernels and license them to third parties.
Although the Company believes that Parasolid is the emerging solid modeling
standard for mid-range MCAD software, there can be no assurance that it will
become the solid modeling standard or that a competitor of the Company will
not develop a solid modeling kernel that will become the standard for the MCAD
industry. If a competitor of the Company were to develop a product that became
the solid modeling standard, it could have a material adverse effect not only
on the future success of Parasolid, but also on the Company's other products
which are based on the Parasolid solid modeling kernel.
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY
 
  The Company's success is heavily dependent upon its proprietary software
technology. The Company relies on a combination of contracts, copyrights,
trade secret laws and patents to establish and protect its proprietary rights
in its technology. Effective copyright, trade secret and patent protection,
however, may be unavailable or limited in certain countries. Litigation, which
could demand financial and management resources, may be necessary to enforce
its copyrights, patents or other intellectual property rights. There can be no
assurance that the steps taken by the Company will be adequate to deter
misappropriation or independent third party development of its technology.
 
  To date, the Company has not been involved in any litigation regarding
copyrights, trademarks, trade secrets or other intellectual property rights
alleging the possible infringement of such intellectual property rights of
others. Litigation alleging infringement of the intellectual property rights
of others is not uncommon in the MCAD and PDM industry and there can be no
assurance that such litigation will not be commenced in the future against the
Company. If litigation were to be commenced against the Company alleging
infringement of the intellectual property rights of others, the Company could
incur significant costs with respect to the defense thereof, irrespective of
the validity or the successful assertion of such claims, which could have a
material adverse effect on the Company's financial condition and results of
operations. See "Business--Intellectual Property" and "--Litigation."
 
COMPETITION
 
  Markets for the Company's products are highly competitive and characterized
by rapidly changing technology and evolving standards. The Company's
competitors include (i) generalist MCAD developers that
 
                                      14
<PAGE>
 
offer broad-range systems, such as Dassault, Matra Datavision, Parametric and
Structural Dynamic Research Corporation ("SDRC"); (ii) specialist software
developers whose product lines are focused on CAD products, CAM products, CAE
products or PDM products; and (iii) numerous smaller niche software
developers.
 
  The Company has experienced and expects to continue to experience strong
competition. The Company's competitors may be able to respond more quickly to
new or emerging technologies and changes in customer requirements or devote
greater resources to the development, promotion and sale of their products
than the Company. Current and potential competitors may establish strategic
alliances or undertake acquisitions to increase the ability of their products
to address the needs of the Company's current and prospective customer base.
For example, Dassault markets and distributes its software products through a
non-exclusive marketing agreement with International Business Machines
Corporation. See "Business--Competition."
 
DECLINING PRICES OF MCAD AND PDM PRODUCTS
 
  As is common in high technology industries, the MCAD industry is
characterized by selling prices which have tended to decline for existing
products over time due to competition, lower marginal costs and rapid
technological change. In particular, increased competition from new sources,
including the introduction of numerous lower priced, higher volume 3-D CAD
products, the emergence of a mid-range market, and the increased penetration
of niche players into the CAM and CAE markets, has led to price pressure on
MCAD software products which is expected to continue. Despite declining unit
prices, the total size of the MCAD global market, as measured by revenue, has
increased over the past several years. See "Business--The MCAD Software
Industry." There can be no assurance, however, the MCAD global market will
continue to grow.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's success depends to a significant extent upon, among other
factors, the continued service of its key senior executives and research and
development, technical, support and other personnel, and on its ability to
continue to attract, retain and motivate qualified personnel. The competition
for such employees is intense, and the loss of the services of any of these
key personnel without adequate replacement or the inability to attract new
qualified personnel could have a material adverse effect on the Company. The
Company will enter into employment contracts with certain executive officers
prior to the consummation of the Offering. The Company generally does not
maintain insurance with respect to the loss of its key personnel. See
"Management."
 
RISKS IN INTERNATIONAL OPERATIONS
 
  As a global participant in the MCAD industry, the Company's business is
subject to various risks beyond its control, such as instability of foreign
economies and governments, changes in laws and policies affecting trade and
investment, fluctuations in exchange rates and the slowdown in European
business activity during the summer months. In 1997, approximately 54% of the
Company's revenue was derived from sales outside the United States. There can
be no assurance that the Company will not experience material adverse effects
on its business and results of operations arising from its international
operations and sales. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
SIGNIFICANT QUARTERLY FLUCTUATIONS
 
  The Company's quarterly operating results have varied significantly and are
likely to vary significantly in the future, depending on factors such as the
number, timing and significance of product enhancements or new products by the
Company or its competitors, the ability of the Company to develop, introduce
and market new and enhanced versions of its products, customer order deferrals
in anticipation of new or enhanced Company products, foreign currency exchange
rates, general conditions in the MCAD and computer industries and regional
economies and other events or factors. A substantial portion of the Company's
orders and shipments typically occur in the last month of each quarter.
Therefore, the timing of orders and shipments, unexpected delays or actions
taken by competitors in reducing prices or introducing new products could
result in significant quarterly fluctuations in the Company's results of
operations. The Company's software revenue, total revenue, operating
 
                                      15
<PAGE>
 
income and net income are generally lower in the first and third quarters of a
given year than in the second and fourth quarters. Additionally, as is typical
in the MCAD software industry, the Company historically has experienced its
highest licensing activity for the year in December. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Quarterly Results of Operations."
 
YEAR 2000 COMPLIANCE
 
  Currently, there is a significant uncertainty in the software industry and
among software users regarding the impact of the year 2000 on installed
software. For example, many customers historically captured only two digit
entries in the date code field. Software database modifications, and/or
implementation modifications, are required to enable such software to
distinguish between 21st and 20th century dates. Current versions of the
Company's products are designed to be "Year 2000" compliant. The Company is in
the process of determining the extent to which the customized implementations
of, and third-party programs for, its software products are Year 2000
compliant, as well as the impact of any non-compliance on the Company and its
customers. The Company does not currently believe that the effects of any Year
2000 non-compliance in the Company's installed base of software will result in
any material adverse impact on the Company's business or results of
operations. However, there can be no assurance that the Company will not be
exposed to potential claims resulting from system problems associated with the
century change.
 
  In accordance with the Management Services Agreement (as hereinafter
defined), the Company will continue to use centralized internal accounting
systems of EDS in the near term. EDS has completed the assessment and planning
stages and has commenced the renovation process for its internal systems,
including those used by the Company. The Company has been advised that EDS
anticipates that this process and the subsequent testing and implementation of
the modified code will be completed in stages, from mid-1998 through mid-1999.
Costs incurred to make EDS' centralized internal accounting systems Year 2000
compliant will be paid entirely by EDS. The failure to complete the Year 2000
conversion process for EDS' internal systems on a timely basis would have a
material adverse impact on the Company's business or results of operations.
 
LIMITED RELEVANCE OF HISTORICAL FINANCIAL INFORMATION
 
  The financial information included herein may not necessarily reflect the
results of operations, financial position and cash flows of the Company in the
future or what the results of operations, financial position and cash flows
would have been had the Company been a separate, stand-alone entity during the
periods presented. The financial information included herein does not reflect
many significant changes that will occur in the funding and operations of the
Company as a result of the Reorganization. In addition, the consolidated
financial statements of the Company include certain assets, liabilities,
revenues and expenses which were not historically recorded at the level of,
but are associated with, the business transferred to the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Pro Forma Financial Information."
 
  There are no financial or operating data, other than statements of assets
sold and revenues and direct expenses, for the Solid Edge/EMS Business for
each of the years in the three-year period ended December 31, 1997, as there
is not sufficient data available to permit the preparation of a complete set
of financial statements in accordance with generally accepted accounting
principles. During such periods, the Solid Edge/EMS Business did not comprise
a separate business unit of Intergraph and was not a material part of its
overall business. As a result, there is only limited financial and operating
information available for a potential investor to evaluate trends in gross
profit, expenses or net income. In addition, because the Solid Edge/EMS
Business was operated as part of the software product business of Intergraph
during each of the years in the three-year period ended December 31, 1997,
various costs incurred by Intergraph during such years were allocated to the
Solid Edge/EMS Business based on estimates described in the notes to the
financial statements included elsewhere in this Prospectus. As a result, the
financial and operating data presented for the Solid Edge/EMS Business for
such years may not reflect the costs and expenses that would have resulted if
the Solid Edge/EMS Business had been operated as a separate entity.
 
                                      16

POTENTIAL ANTI-TAKEOVER CONSIDERATIONS
 
  Under the Company's Certificate of Incorporation, the Board of Directors has
the authority, without action by the Company's stockholders, to fix certain
terms and issue shares of Preferred Stock, par value $.01 per share (the
"Preferred Stock"), and to issue rights to purchase securities or other
property from the Company. Actions of the Board of Directors pursuant to this
authority may have the effect of delaying, deterring or preventing a change in
control of the Company. Other provisions in the Company's Certificate of
Incorporation and in the Restated Bylaws (the "Bylaws") impose procedural and
other requirements, including the requirement that a vote of more than 80% of
the voting stock of the Company is necessary for stockholders to amend the
Bylaws and certain provisions of the Certificate of Incorporation. These
requirements could make it more difficult to effect certain corporate actions,
including replacing incumbent directors. In addition, the Board of Directors
is divided into three classes, each of which is to serve for a staggered
three-year term after the initial classification and election, and, after EDS
ceases to be the beneficial owner of an aggregate of at least a majority of
the voting power of the Company, incumbent directors may not be removed
without cause, all of which may make it more difficult for a third party to
gain control of the Board of Directors. With certain exceptions, Section 203
of the Delaware General Corporation Law (the "DGCL") imposes certain
restrictions on mergers and other business combinations between the Company
and any holder of 15% or more of the voting stock of the Company. Section 203
does not apply to EDS' interest in the Company. See "Description of Capital
Stock--Certificate of Incorporation and Bylaw Provisions."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Subject to applicable law, EDS may sell any and all of the shares of Common
Stock it owns after completion of the Offering. EDS and the Company have
agreed, however, subject to certain exceptions, not to sell or otherwise
dispose of any shares of Class A Common Stock (other than the shares offered
hereby or pursuant to employee stock option plans which exist on, or are
described herein to be implemented after, the date of this Prospectus) for a
period of 180 days after the date of this Prospectus without the prior written
consent of Morgan Stanley & Co. Incorporated, on behalf of the Underwriters.
In connection with the Offering, the Company and EDS have entered into an
agreement which provides that EDS will have certain rights to have shares of
Common Stock owned by it after the Offering registered by the Company under
the Securities Act of 1933, as amended (the "Securities Act"), in order to
permit the public sale of such shares. In addition, beginning one year after
EDS acquired its shares of Common Stock, EDS will be permitted to sell in the
public market specified amounts of such Common Stock without registration
pursuant to Rule 144 under the Securities Act ("Rule 144"). No prediction can
be made as to the effect, if any, that future sales of Common Stock by EDS, or
the availability of Common Stock for future sale, will have on the market
price of the Class A Common Stock prevailing from time to time. Sales of
substantial amounts of Common Stock, or the perception that such sales could
occur, could adversely affect prevailing market prices for the Class A Common
Stock. See "Shares Eligible for Future Sale."
 
ABSENCE OF A PRIOR PUBLIC MARKET; VOLATILITY OF PRICE
 
  Prior to the Offering, there has been no public market for the Class A
Common Stock and there can be no assurance that an active trading market will
develop or be sustained. The initial public offering price of the Class A
Common Stock will be determined through negotiation between the Company and
the Underwriters and may not be indicative of the market price for the Class A
Common Stock after the Offering. See "Underwriters."
 
  The market price for the Class A Common Stock may be highly volatile. The
Company believes that factors such as announcements by it, or by its
competitors, of quarterly financial results could cause the market price of
the Class A Common Stock to fluctuate substantially. The stock market has from
time to time experienced extreme price and volume fluctuations which have
particularly affected the market prices for many high technology companies. In
addition, the stock market may experience extreme price and volume
fluctuations which often are unrelated to the operating performance of
specific companies. Market fluctuations or perceptions regarding the Company's
industry, as well as general economic or political conditions, may adversely
affect the market price of the Class A Common Stock.

DILUTION
 
  Purchasers of the Class A Common Stock in the Offering will experience
immediate and substantial dilution in the amount of $    in the net tangible
book value per share of Class A Common Stock from the initial public offering
price. See "Dilution."
 
NO INTENTION TO PAY DIVIDENDS
 
  The Company intends to retain its earnings to finance future growth and,
therefore, does not anticipate paying any cash dividends on its Common Stock
in the foreseeable future.
 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
  Certain statements contained herein under "Prospectus Summary," "Risk
Factors," Pro Forma Financial Information, "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business"
including, without limitation, those concerning (i) the integration of the
Solid Edge/EMS Business into the Company's operations, (ii) the success of
establishing Parasolid as a solid modeling standard for MCAD software, (iii)
the schedule for developing and releasing new software, (iv) the capabilities
of new software, (v) the Company's continuing relationship with EDS, (vi)
future sales activities and (vii) Year 2000 compliance contain certain
forward-looking statements concerning the Company's operations, economic
performance and financial condition. Because such statements involve risks and
uncertainties, actual results may differ materially from those expressed or
implied by such forward-looking statements. Factors that could cause such
differences include, but are not limited to, those discussed under "Risk
Factors."

                                USE OF PROCEEDS
 
  The Company will receive approximately $    million from the sale of Class A
Common Stock in the Offering (approximately $    million if the U.S.
Underwriters' option is exercised in full) after deducting underwriting
commissions and estimated expenses payable by the Company, assuming an initial
public offering price of $    per share (the mid-point of the filing range
appearing on the cover of this Prospectus). Approximately $    million of the
net proceeds of the Offering will be used to repay outstanding indebtedness
under the Intercompany Credit Agreement which was incurred to pay the purchase
price and certain expenses in connection with the Solid Edge Acquisition.
Borrowings by the Company under the Intercompany Credit Agreement bear
interest at a rate equal to the one-month London Interbank Offered Rate
("LIBOR") plus 0.5%. Approximately $    million of the net proceeds of the
Offering will be used to repay amounts outstanding under the Intercompany
Note. The Intercompany Note bears interest, payable semiannually, at a rate
equal to the one-month London Interbank Bid Rate ("LIBID") minus 0.5%. See
"Relationship with EDS and Certain Transactions."
 
                                DIVIDEND POLICY
 
  The Company currently intends to retain its earnings to finance future
growth and, therefore, does not anticipate paying any cash dividends on its
Common Stock in the foreseeable future. Any future determination as to the
payment of dividends will depend upon the future results of operations,
capital requirements and financial condition of the Company and such other
factors as the Board of Directors may consider, including any contractual or
statutory restrictions on the Company's ability to pay dividends.

                                   DILUTION
 
  The pro forma net tangible book value of the Company at December 31, 1997,
giving effect to the Reorganization, the Solid Edge Acquisition and the
Intercompany Note, was approximately $(99.7) million, or $    per share of
Common Stock. Net tangible book value per share of Common Stock represents the
amount of total tangible assets less total liabilities, divided by the total
number of shares of Common Stock outstanding.
 
  Dilution per share represents the difference between the amount per share
paid by purchasers of shares of Class A Common Stock in the Offering and the
pro forma net tangible book value per share of Common Stock immediately after
the completion of the Offering. After giving effect to the sale of
approximately   million shares of Class A Common Stock at an assumed price of
$    per share by the Company in the Offering and the application of the
estimated net proceeds therefrom, the pro forma net tangible book value of the
Company as of December 31, 1997 would have been approximately $    million, or
$   per share of Common Stock. This represents an immediate dilution in pro
forma net tangible book value per share of $    to investors who purchase
shares of Class A Common Stock in the Offering. The following table
illustrates the dilution in pro forma net tangible book value per share to
such investors:

                        PRO FORMA FINANCIAL INFORMATION
 
  The following unaudited pro forma condensed combined financial information
consists of an unaudited Pro Forma Condensed Combined Balance Sheet as of
December 31, 1997 and the related unaudited Condensed Combined Statement of
Operations for the year ended December 31, 1997 (collectively, the "Pro Forma
Statements") and are based upon the historical financial statements of the
Company and the Solid Edge/EMS Business. The Pro Forma Statements reflect
adjustments to the historical financial statements to give effect for certain
transactions which have either occurred or are probable to occur. The
unaudited Pro Forma Condensed Combined Balance Sheet has been prepared
assuming that the Solid Edge Acquisition, the Reorganization, the issuance of
the Intercompany Note and the Offering and the application of the estimated
proceeds therefrom occurred on December 31, 1997, and the Pro Forma Condensed
Combined Statements of Operations have been prepared assuming that the Solid
Edge Acquisition, the Reorganization, the issuance of the Intercompany Note
and the Offering and the application of the estimated proceeds therefrom
occurred on January 1, 1997.
 
  The Solid Edge Acquisition was accounted for as a purchase. The purchase
price has been allocated in the Pro Forma Statements to the assets acquired
based on estimated fair values at the date of acquisition. The allocation of
the purchase price is subject to change based on the completion of an
independent appraisal. Management does not believe that the final allocation
of the purchase price or the related useful lives assigned to the acquired
assets will be materially different from the preliminary amounts presented in
the Pro Forma Statements.
 
  The pro forma information is presented for illustrative purposes only and is
not necessarily indicative of the operating results or financial position that
would have occurred if the transactions had been consummated as presented in
the accompanying Pro Forma Statements, nor is it necessarily indicative of
future results of operations.
 
  The Pro Forma Statements should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the financial statements and related notes thereto of the Company and the
Solid Edge/EMS Business included elsewhere herein.

                         NOTES TO PRO FORMA STATEMENTS
 
  The accompanying Pro Forma Condensed Combined Balance Sheet as of December
31, 1997 reflects the following pro forma adjustments for the Acquisition, the
Reorganization, the issuance of the Intercompany Note and the Offering and the
application of the estimated net proceeds therefrom as if such transactions
had occurred on December 31, 1997.
 
(a) To record the contribution of EDS's net investment in its MCAD businesses
    and divisions to the Company.
(b) To record the purchase of the Solid Edge/EMS Business for $107 million,
    including acquisition costs. The transaction has been accounted for as a
    purchase. The purchase price has been allocated to the assets acquired on
    a preliminary basis based on estimated fair values at the date of
    acquisition. Such values are estimated to be as follows (in thousands):

</TABLE>
 
    Amounts assigned to in-process research and development costs were expensed
    upon acquisition and are shown net of related deferred income taxes of
    $15.6 million.
 
(c) To eliminate the historical net assets balance relating to the Solid
    Edge/EMS Business.
(d) To record the issuance of the Intercompany Note in the principal amount of
    $73.0 million to EDS as a dividend effective March 6, 1998.
(e) To record the issuance of Class A Common Stock of the Company pursuant to
    the Offering, resulting in net proceeds of approximately $100 million, and
    the issuance of Class B Common Stock in exchange for all the outstanding
    shares of the Company's Common Stock owned by EDS immediately prior to the
    Offering. Such net proceeds assume that the U.S. Underwriters' over-
    allotment option is not exercised.
(f) To record the repayment of a portion of the outstanding borrowings under
    the Intercompany Credit Agreement with the net proceeds from the Offering.
 
    The accompanying Pro Forma Condensed Combined Statement of Operations for
the year ended December 31, 1997 reflects the following pro forma adjustments,
assuming the Solid Edge Acquisition, the Reorganization, the issuance of the
Intercompany Note and the Offering and the application of the estimated net
proceeds therefrom had occurred on January 1, 1997.
 
(g) To reflect additional amortization expense on $63.7 million of intangibles
    acquired in the Solid Edge Acquisition, assuming a weighted average useful
    life of five years. Pro forma depreciation expense associated with
    property and equipment acquired in the Solid Edge Acquisition is assumed
    to be consistent with historical depreciation expense. The Pro Forma
    Condensed Combined Statement of Operations does not reflect the write-off
    of in-process research and development costs of $42.0 million in
    connection with the Solid Edge Acquisition.
 
(h) To record interest expense resulting from borrowings under the
    Intercompany Credit Agreement of $107.0 million in connection with the
    Solid Edge Acquisition and the $73.0 million Intercompany Note issued as a
    dividend to EDS. All such indebtedness is assumed to bear interest at 6.5%
    for the year ended December 31, 1997.
(i) To record the estimated tax impact of pre-tax income statement adjustments
    at the Company's 1997 effective tax rate of 37.2%.
(j) To record the reduction of interest expense (using a 6.5% interest rate)
    in connection with the repayment of a portion of the outstanding
    borrowings under the Intercompany Credit Agreement with the net proceeds
    of the Offering.
(k) Diluted earnings per share has not been presented for the Company's
    historical statement of operations as the Company was operated within
    several business units of EDS and not as a separate legal division or
    subsidiary. The pro forma earnings per common share data is calculated
    using the total shares of Common Stock expected to be outstanding after
    the Offering (   million shares). Employee stock options for     shares of
    Class A Common Stock to be issued upon completion of the Offering at the
    initial public offering price are assumed to have no dilutive effect on
    earnings per share. The Company plans on accounting for its employee stock
    options under APB Opinion No. 25, "Accounting for Stock Issued to
    Employees."

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following is a discussion and analysis of the financial condition and
results of operations of the Company prior to the Solid Edge Acquisition,
unless otherwise specifically stated. For a discussion of the Solid Edge
Acquisition, see "--Solid Edge Acquisition."
 
OVERVIEW
 
  The Company generates revenue primarily from the licensing of MCAD and PDM
software products, provision of software consulting and support services and
computer equipment sales to users of the Company's products. The Company
operates business units in the United States and more than 20 other countries.
The Company's software products are licensed to customers through the
Company's direct sales force and by specific arrangements with certain
distributors, value-added resellers ("VARs") and other marketing
representatives. The Company also offers a full range of customization,
implementation and integration consulting services.
 
  Effective as of January 1, 1998, the Company succeeded to the MCAD business
of EDS which had previously been operated within several business units of
EDS. The Company's historical financial statements reflect the results of
operations, financial condition and cash flows of the Company as a component
of EDS prior to the Reorganization and may not be indicative of actual results
of operations and financial position of the Company subsequent to the
Reorganization. See "Risk Factors--Risks Associated with Absence of History as
a Stand-Alone Company and Integration of Solid Edge/EMS Business," "--Limited
Relevance of Historical Financial Information" and "Selected Financial and
Operating Data."
 
  The Company's customers may license only software products or software
products coupled with customization, implementation, consulting and/or
maintenance services. Pricing for software licenses is based on the
configuration of the Company's products selected by the customer on a per seat
basis or pursuant to a site license for multiple seats. The MCAD software
industry is characterized by selling prices which have tended to decline for
existing software products over time due to competition, lower marginal costs
and rapid technological change.
 
  The Company typically licenses software to customers under perpetual or term
license arrangements. Revenue on such perpetual arrangements is recognized
upon delivery of the software or as seats are installed, depending on the
terms of the arrangement and providing all revenue recognition criteria have
been met. Revenue on term license arrangements is recognized ratably over the
license term. Software revenue also includes royalty revenue related to the
licensing of Parasolid to third-party software developers.
 
  Services revenue includes revenue from maintenance and consulting services.
Revenue attributable to maintenance services is recognized ratably over the
maintenance period. Maintenance fees entitle customers to the receipt of
product upgrades as well as customer support. Maintenance fees generate
recurring revenue and thereby provide a degree of stability to the Company's
results of operations. The Company typically provides maintenance services to
its customers on an annual basis with automatic renewals subject to the
Company's or the customer's right to terminate the maintenance upon 60 days
prior notice. The average maintenance renewal rate over the past five years
has been approximately 98%. Consulting and other services consist primarily of
customer training, implementation and integration, engineering and data
exchange services.
 
  Hardware revenue results from the sale of bundled hardware/software products
to certain customers. Hardware consists of computer hard drives, monitors and
related equipment which is typically purchased through EDS and resold to
customers. In late 1996, the Company began deemphasizing hardware sales in
order to focus on higher margin software sales and consulting services.
Therefore, hardware revenue declined in 1997 and is expected to continue to
decline in the future.
 
  In 1996, the Company's parent, EDS, entered into the EDS/GM Site License
Agreement with GM which provides for the delivery of up to 10,000 seats of
Unigraphics and IMAN as well as the provision of maintenance
 
                                      27
<PAGE>
 
services for an initial term of three years. By recognizing Unigraphics as its
single MCAD product development system, GM has expressed its intent to
consolidate its usage of MCAD software systems. Prior to the EDS/GM Site
License Agreement, GM received software and maintenance services on a monthly
basis pursuant to a term lease agreement which was cancelable upon notice. In
connection with the Reorganization, EDS and the Company entered into the GM
Subcontract pursuant to which the Company receives all revenue and performs
substantially all of EDS' obligations under the EDS/GM Site License Agreement.
As a result of the EDS/GM Site License Agreement, the Company recognized
software revenue of $110.3 million in the second half of 1996, primarily in
the fourth quarter. Maintenance revenue relating to the EDS/GM Site License
Agreement is being recognized by the Company over the maintenance period.
Although less than 10% of the Company's 1997 revenues were attributable to the
products and services provided to GM, receivables of $55.2 million, or
approximately 48% of the Company's accounts receivable balance, at December
31, 1997 were related to products and services provided to GM. If the EDS/GM
MSA were to be terminated, or if the Company (as a subcontractor to EDS) and
GM were not to enter into a successor agreement to the EDS/GM Site License
Agreement upon termination of that agreement in 1999, the Company's financial
condition and results of operations would be materially adversely affected.
 
  Effective January 1, 1998, the Company and EDS entered into the Management
Services Agreement, pursuant to which EDS performs various management services
for the Company including treasury, risk management and tax, and similar
administrative services. Amounts charged to the Company under this agreement
approximate EDS' cost of providing the services plus a fixed fee equal to 0.5%
of the Company's total revenues. The Management Services Agreement will expire
on December 31, 2002 unless terminated earlier by either party if EDS and the
Company are no longer under common control. Except for certain tax and
treasury management services relating to consolidated operations or corporate
policy of EDS, which the Company is required to purchase during the term of
the Management Services Agreement, the Company or EDS may terminate any
service on or after January 1, 2000 with prior notice of not less than five
months. The Company's historical financial statements include an allocation of
corporate general and administrative costs in the amount of approximately 2.1%
of total revenues per year. Management believes that this percentage, which is
based on an analysis of actual services and estimated costs provided to the
Company by EDS, is reasonable. However, there can be no assurance that such
costs will be indicative of costs to be incurred under the Management Services
Agreement or in transactions with unrelated third parties. The Company expects
to pay EDS approximately $8.5 million for such services in 1998, subject to
adjustment levels and negotiated prices.
 
SOLID EDGE ACQUISITION
 
  On March 2, 1998, the Company completed the Solid Edge Acquisition for a
purchase price of $105 million (excluding approximately $2 million of
acquisition costs). The Company borrowed $107 million from EDS pursuant to the
Intercompany Credit Agreement. The cost of the Solid Edge Acquisition will be
allocated to identifiable assets based on estimated fair values as determined
by an independent appraisal. Costs allocated to identifiable intangible assets
will be amortized on a straight-line basis over the remaining estimated useful
lives of the assets. Based on a preliminary purchase price allocation, costs
were allocated to in-process research and development in the amount of $42.0
million and will be expensed in the three month period ended March 31, 1998.
The excess of purchase price over fair value of identifiable assets acquired
will be recorded as software and other intangibles and amortized on a
straight-line basis over its useful life. On a preliminary basis, the Company
has allocated the purchase price as follows: $1.3 million to computer
equipment, furniture and other assets; $63.7 million to software and other
intangibles; and $42.0 million to in-process research and development costs.
Such allocation is subject to change upon receipt of an independent appraisal.
As a result of the write-off of in-process research and development costs and
additional amortization expense resulting from the Solid Edge Acquisition, the
Company expects that net income in 1998 will be significantly less than in
prior years.
 
  Revenues of the Solid Edge/EMS Business totaled $34.5 million, $31.9 million
and $35.2 million during 1995, 1996 and 1997, respectively. Sales of Solid
Edge commenced in 1996. Revenues attributable to Solid Edge
 
                                      28
<PAGE>
 
product and services represented 22% and 46% of total revenues of the Solid
Edge/EMS Business during the years ended December 31, 1996 and 1997,
respectively. Revenues related to EMS declined from $34.5 million in 1995 to
$19.0 million in 1997 primarily due to the introduction of Solid Edge in 1996.
Management expects that revenues attributable to the EMS product will continue
to decline in the future. Research and development costs of $12.1 million,
$10.9 million and $10.0 million in 1995, 1996 and 1997, respectively,
primarily related to the development of the Solid Edge product. The excess of
direct expenses over revenues of the Solid Edge/EMS Business were $6.3
million, $10.1 million and $4.1 million during 1995, 1996 and 1997,
respectively.

December 31, 1997, a decrease of $99.6 million from $414.2 million in 1996.
The decrease in total revenue was due to the recognition of software license
revenue in 1996 pursuant to the EDS/GM Site License Agreement, which resulted
in the recognition of license revenue totaling $110.3 million. Revenue related
to GM totaled $18.6 million in 1997 compared to $139.4 million in 1996. Non-GM
revenue totaled $296.0 million, an increase of $21.2 million, or 8%, over 1996
non-GM revenue of $274.8 million. The increase in non-GM revenue in 1997 was
due to additional sales of software seats and increased maintenance revenue,
partially offset by decreases in sales of computer equipment.
 
  Software revenue decreased $94.0 million to $115.5 million in 1997 due to
recognition of GM revenue in 1996 in connection with the signing of the EDS/GM
Site License Agreement. Non-GM software revenue increased $26.2 million, or
29%, in 1997 primarily due to the licensing of the Unigraphics product suite
to a number of new aerospace customers as a result of increased functionality
available in Versions 12.0 and 13.0 of Unigraphics released in 1997.
 
  Services revenue increased $16.3 million, or 13%, to $137.8 million in 1997
from $121.5 million in 1996. This increase was primarily attributed to
increased maintenance revenue due to continued growth in the Company's
installed customer base and increased training, implementation and integration
consulting services provided to licensees of the Company's software.
 
  Hardware revenue decreased $21.9 million, or 26%, to $61.3 million in 1997
from $83.2 million in 1996. In late 1996, the Company began deemphasizing
hardware sales in order to focus on higher margin software
 
                                      30
<PAGE>
 
sales and consulting services. Therefore, hardware revenue declined in 1997
and is expected to continue to decline in the future.
 
  The Company derived 54% and 40% of its revenue from international operations
during 1997 and 1996, respectively. Excluding GM revenue, international
revenue accounted for 58% and 60% of total revenue in 1997 and 1996,
respectively. Revenue from Asia Pacific increased $7.1 million in 1997 due to
increased software revenue in Japan, China and Korea. These increases were
partially offset by a decline in revenue in Europe of $4.4 million, primarily
resulting from reduced hardware revenue in Eastern Europe and Germany. Results
of operations of the Company have not been materially affected by the currency
volatility in Asia Pacific markets in late 1997.
 
  Gross Profit. The Company's gross profit was $185.5 million in 1997 as
compared to $274.4 million in 1996, a decrease of $88.9 million. Gross profit
margin was 59% and 66% in 1997 and 1996, respectively. The decrease in gross
profit margin in 1997 is due to the exceptionally high proportion of software
revenue to total revenue in 1996 as a result of revenue attributable to the
EDS/GM Site License as well as a slight decline in the gross profit margin for
services. Cost of software revenue was $28.0 million and $38.5 million in 1997
and 1996, respectively. Gross profit on service revenue increased $0.9 million
to $80.7 million in 1997 from $79.8 million in 1996. Gross profit margin on
service revenue declined to 59% in 1997 from 66% in 1996 principally due to a
higher proportion of consulting and other revenue to total service revenue as
well as increased staffing in the U.S. and Asia Pacific regions. Gross profit
on hardware revenue decreased $6.4 million to $17.2 million in 1997 from $23.6
million in 1996. Gross profit margin on hardware revenue was 28% in 1997 and
1996. Cost of software revenue includes amortization of $13.4 million per year
relating to EDS' acquisition of Unigraphics in 1991, which amortization is
expected to continue through October 1999.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses totaled $102.8 million in 1997, an increase of $10.4
million from $92.4 million in 1996. Selling, general and administrative
expenses represented 33% and 22% of total revenues in 1997 and 1996,
respectively. Exclusive of GM revenues, selling, general and administrative
costs represented 35% and 34% of 1997 and 1996 revenues, respectively. Selling
costs are comprised of salesperson salaries, commissions and benefits, travel,
sales office occupancy and other related costs. The increase of $10.4 million
in selling, general and administrative costs was principally due to increased
selling costs due to increases in non-GM sales and expansion of the Company's
U.S. and Asia Pacific sales operations. Such increase was partially offset by
lower allocations of corporate general and administrative expenses from EDS
due to lower total revenue.
 
  Research and Development Costs. Research and development costs were $48.0
million and $47.2 million in 1997 and 1996, respectively. Research and
development costs as a percentage of total revenue were 15% and 11% in 1997
and 1996, respectively. Research and development costs as a percentage of
total revenue in 1996 were lower than in 1997 due primarily to increased
revenue associated with the EDS/GM Site License Agreement in 1996.
 
  Operating Income. Operating income was $34.7 million in 1997 as compared to
$134.8 million in 1996.
 
  Other Income, Net. Other income, net was $5.1 million in 1997 as compared to
$0.1 million in 1996. During 1997, the Company realized gains upon the
exercise of warrants and subsequent sale of related marketable equity
securities of $5.1 million. The warrants were received in exchange for reduced
royalty fees from a private software company which was acquired by a public
company in 1997. The Company anticipates that significant gains on similar
transactions will also be reflected in its results of operations in 1998. The
amount of such gains will be dependent on the timing of the Company's vesting
in related warrants and existing market conditions at the date of sale.
 
  Provision for Income Taxes. The provision for income taxes was $14.8 million
in 1997 compared to $51.5 million in 1996. The Company's effective tax rate
was 37.2% and 38.2% in 1997 and 1996, respectively. The difference between the
Company's effective tax rate and the statutory federal income tax rate
primarily resulted from state and foreign taxes, partially offset by research
and experimentation credits.
 
                                      31

  Net Income. Net income was $25.0 million and $83.3 million in 1997 and 1996,
respectively.
 
 YEARS ENDED DECEMBER 31, 1996 AND 1995
 
  Revenue. Revenue of the Company was $414.2 million during the year ended
December 31, 1996, an increase of $146.6 million from $267.6 million in 1995.
The increase in total revenue was principally due to the recognition of
software license revenue upon the signing of the EDS/GM Site License Agreement
in 1996. Revenue related to GM totaled $139.4 million in 1996 compared to
$36.6 million in 1995. Non-GM revenue totaled $274.8 million, an increase of
$43.8 million, or 19%, over 1995 non-GM revenue of $231.0 million.
 
  Software revenue increased $120.4 million to $209.5 million in 1996
primarily due to the signing of the EDS/GM Site License Agreement. Non-GM
software revenue increased $15.8 million, or 22%, in 1996. The increase in
non-GM revenue was due to the introduction of Version 11.0 of Unigraphics
which was the Company's first MCAD product capable of handling large, complex
design assemblies with hundreds of components, making it especially well
suited for automotive and aerospace manufacturers. In addition, certain
modules associated with Unigraphics 11.0 were specifically designed for the
commercial automotive market which the Company believes enabled EDS to obtain
the EDS/GM Site License Agreement. Furthermore, licenses of software to
suppliers of GM increased as a result of GM's decision to standardize its
operations using a single MCAD product.
 
  Services revenue increased $9.9 million, or 9%, to $121.5 million in 1996
from $111.6 million in 1995. This increase is primarily attributed to
increased maintenance revenue due to growth in the Company's installed
customer base and increased training, implementation and integration
consulting services provided to licensees.
 
  Hardware revenue increased $16.3 million, or 24%, to $83.2 million in 1996
from $66.9 million in 1995. Hardware revenue increased primarily due to
increased sales in Europe which typically consisted of bundled hardware and
software products.
 
  The Company derived 40% and 49% of its revenue from international operations
during 1996 and 1995, respectively. International revenue accounted for 60%
and 57% of total revenue, exclusive of GM revenue, in 1996 and 1995,
respectively. Revenue from Europe increased $20.8 million in 1996, primarily
due to increased software and hardware revenue in most European countries.
Revenue from Asia Pacific increased $7.1 million in 1996, principally due to
increased software revenue in China, Singapore and Australia.
 
  Gross Profit. The Company's gross profit was $274.4 million in 1996 as
compared to $158.6 million in 1995, an increase of $115.8 million. Gross
profit margin was 66% and 59% in 1996 and 1995, respectively. The increase in
gross profit margin in 1996 was due to the exceptionally high proportion of
software revenue to total revenue in 1996 as a result of revenue attributable
to the EDS/GM Site License Agreement. Cost of software sales was $38.5 million
and $27.5 million in 1996 and 1995, respectively. Gross profit on services
revenue increased $2.6 million to $79.8 million in 1996 from $77.2 million in
1995. Gross profit margin on services revenue declined to 66% in 1996 from 69%
in 1995 principally due to a higher proportion of consulting and other service
revenue to total service revenue. Gross profit on hardware revenue increased
$3.9 million to $23.6 million in 1996 from $19.7 million in 1995. Gross profit
margin on hardware revenue was 28% and 29% in 1996 and 1995, respectively.
Cost of software revenue includes amortization of $13.4 million per year
relating to EDS' acquisition of Unigraphics in 1991, which amortization is
expected to continue through October 1999.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses totaled $92.4 million in 1996, an increase of $7.4
million from $85.0 million in 1995, of which $3.1 million was attributable to
the increased allocation for general and administrative expense from EDS due
to higher revenue and the remainder was due to increased selling costs
resulting from higher sales as well as expansion of foreign operations.
Selling, general and administrative expenses represented 22% and 32% of total
revenue in 1996 and 1995, respectively. Exclusive of GM revenue, selling,
general and administrative costs represented 34% and 37% of 1996 and 1995
revenue, respectively.
 
                                      32
<PAGE>
 
  Research and Development Costs. Research and development costs were $47.2
million and $43.7 million in 1996 and 1995, respectively. Research and
development costs as a percentage of total revenue were 11% and 16% in 1996
and 1995, respectively. The increase in research and development costs was
primarily due to the capitalization of $3.3 million of product development
costs in 1995.
 
  Operating Income. Operating income was $134.8 million in 1996 as compared to
$29.9 million in 1995.
 
  Provision for Income Taxes. The provision for income taxes was $51.5 million
in 1996 compared to $11.6 million in 1995. The Company's effective tax rate
was 38.2% and 38.7% in 1996 and 1995, respectively. The difference between the
Company's effective tax rate and the statutory federal income tax rate
primarily results from state and foreign income taxes.
 
  Net Income. Net income was $83.3 million and $18.4 million in 1996 and 1995,
respectively.

  The Company's total revenue for the first, second, third and fourth quarters
of 1997 represented 22%, 26%, 24% and 28%, respectively, of total revenue for
1997. In 1996, the first, second, third and fourth quarters represented 17%,
20%, 18% and 45%, of total revenue for the year. The Company's quarterly
operating results have varied significantly and are likely to vary
significantly in the future, depending on factors such as number, timing and
significance of product enhancements or new products by the Company or its
competitors, the ability of the Company to develop, introduce and market new
and enhanced versions of its products, general conditions in the MCAD and
computer industries and regional economies and other events and factors.

  The Company's first quarter software revenue, total revenue, operating
income and net income have generally been the lowest of any quarter during the
year. Additionally, as is typical in the MCAD software industry, the Company
historically has experienced its highest licensing activity each year in the
fourth quarter.
 
  Revenue and cost of revenue relating to software increased in the fourth
quarter of 1996 primarily due to the signing of the EDS/GM Site License
Agreement resulting in the recognition of software revenue totaling $101.1
million in that quarter. Total software revenue recognized by the Company
under the EDS/GM Site License Agreement in 1996 was $110.3 million. See "--
Results of Operations" for further discussion as to the impact of the EDS/GM
Site License Agreement.
 
  The Company expects that net income for the first quarter of 1998 will be
significantly less than in prior years as a result of the Solid Edge
Acquisition. The Company expects to allocate approximately $42 million of the
purchase price of the Solid Edge/EMS Business to in-process research and
development which the Company will expense in the first quarter of 1998. The
Company's results of operations for the first quarter of 1998 will also
reflect amortization of acquired software of approximately $1 million
associated with the Solid Edge Acquisition. Such amortization will be recorded
as cost of software revenue. See "--Solid Edge Acquisition" for a discussion
of the impact of the Solid Edge Acquisition on the financial statements and
results of operations of the Company, including with respect to the first
quarter of 1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Historically, the Company has utilized the central cash management function
of EDS to finance its operations. Cash requirements were satisfied either by
intercompany transactions between EDS and the Company or by cash from
operations. Intercompany transactions between EDS and the Company did not bear
interest. In connection with the Reorganization, EDS and the Company entered
into the Intercompany Credit Agreement which provides the Company with funding
to meet its daily cash requirements. Under the Intercompany Credit Agreement,
the interest rate to be charged to the the Company is the sum of the one-month
LIBOR plus 0.5%. In addition, the Company is required, with minor exceptions,
to lend any excess cash it has available to EDS, with such loans to bear
interest at a rate equal to the one-month LIBID minus 0.5%. Subsequent to the
Offering, the maximum amount that the Company may borrow at any time from EDS
under the Intercompany Credit Agreement (and certain other credit agreements
between EDS Finance plc, a wholly-owned subsidiary of EDS, and certain non-
U.S. subsidiaries of the Company) will be $70.0 million. The Intercompany
Credit Agreement restricts the Company from obtaining financing from any party
other than EDS without written consent from EDS, unless EDS fails to provide
funding available to the Company under the Intercompany Credit Agreement. See
"Relationship with EDS and Certain Transactions--Contractual Arrangements--
Intercompany Credit Agreement."
 
  In connection with the Solid Edge Acquisition, the Company borrowed $107.0
million under the Intercompany Credit Agreement on March 2, 1998. In addition,
effective March 6, 1998, the Company issued to EDS as a dividend the
Intercompany Note in the principal amount of $73.0 million. The Intercompany
Note is payable on March 6, 2001 and bears interest, payable semiannually, at
a rate equal to the one-month LIBID minus 0.5%. A portion of the amounts
advanced to the Company under the Intercompany Credit Agreement in respect of
the Solid Edge Acquisition will be repaid to EDS with the net proceeds from
the Offering.
 
  The Company generated net cash from operating activities of $43.3 million,
$53.8 million and $74.3 million in 1995, 1996 and 1997, respectively. Net cash
used in investing activities was $7.4 million, $12.4 million and $4.1 million
in 1995, 1996 and 1997, respectively. Included in investing activities for
these years were capital expenditures of $6.6 million, $12.3 million and $9.1
million, respectively. At December 31, 1997, the Company had an unbilled
receivable from GM of $55.2 million relating to the software revenue
recognized in 1996 under the EDS/GM Site License Agreement. Such receivable is
scheduled to be paid in 1998 and the first half of 1999. The Company believes
currently available sources of liquidity, including the Intercompany Credit
Agreement and cash generated from operations, will be sufficient for its
operations in the foreseeable future.

YEAR 2000 ISSUE
 
  Current versions of the Company's products are designed to be Year 2000
compliant. The Company is in the process of determining the extent to which
the customized implementations of its software products are Year 2000
compliant, as well as the impact of any non-compliance on the Company and its
customers. While there can be no assurance that the Company will not be
exposed to potential claims resulting from system problems associated with the
Year 2000 issue, the Company does not currently believe that the effects of
any Year 2000 non-compliance in the Company's installed base of software will
result in any material adverse impact on the Company's business or results of
operations.
 
  In accordance with the Management Services Agreement with EDS, the Company
will continue to use centralized internal accounting systems of EDS in the
near term. EDS has completed the assessment and planning stages and has
commenced the renovation process for its internal systems, including those
used by the Company. The Company has been advised that EDS anticipates that
this process and the subsequent testing and implementation of the modified
code will be completed in stages, from mid-1998 through mid-1999. Costs
incurred to make EDS' centralized internal accounting systems Year 2000
compliant will be paid entirely by EDS. The failure to complete the Year 2000
conversion process for EDS' internal systems on a timely basis would have a
material adverse impact on the Company's business or results of operations.
 
IMPACT OF CHANGES IN EXCHANGE RATES
 
  The Company's results of operations can be affected by changes in exchange
rates. Revenue received and expenses paid in currencies other than the U.S.
dollar are translated into U.S. dollars for financial reporting purposes based
on the average exchange rate for the period. During the year ended December
31, 1997, international revenue and operating income represented 54% and 56%,
respectively, of total revenue and operating income of the Company. The
Company's most significant international operations are located in Germany and
the United Kingdom, which comprised 20% and 16%, respectively, of total
international revenue in 1997. Foreign revenue and costs are generally
received and paid in the local currency. Historically, foreign currency
transaction gains (losses) have not had a material effect on the Company's
operations.
 
INFLATION
 
  Historically, inflation has not had a material effect on the Company's
results of operations.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, SFAS No. 130, Reporting Comprehensive Income, and SFAS No.
131, Disclosures about Segments of an Enterprise and Related Information, were
issued. SFAS No. 130 establishes standards for reporting and displaying
comprehensive income and its components in a financial statement that is
displayed with the same prominence as other financial statements.
Reclassification of financial statements for earlier periods, provided for
comparative purposes, is required. The statement also requires the accumulated
balance of other comprehensive income to be displayed separately from retained
earnings and additional paid-in capital in the equity section of the statement
of financial position. SFAS No. 131 establishes standards for reporting
information about operating segments in annual and interim financial

                                   BUSINESS
 
  The Company is a leading global provider of scalable, integrated,
enterprise-level MCAD solutions that are used for virtual product development
principally in the automotive and transportation, aerospace, consumer
products, equipment and machinery and electronics industries. The Company's
MCAD solutions consist of both software products and consulting services. The
Company's software products allow customers to reduce design, engineering and
manufacturing costs and minimize the time between a product's inception and
its introduction to the market while simultaneously improving product quality.
Through MCAD, product design is accomplished digitally, eliminating the need
for paper drawings or physical prototypes. With digital assemblies, fit,
tolerances and moving mechanisms, as well as design alternatives, can be
tested before a physical product has been made. For example, automobile
designers can virtually "open" the door or trunk and can "walk around" a
digital 3-D model of a car to assess its design. MCAD systems produce large
volumes of data which can be managed by the Company's PDM software. The
Company's PDM software makes the most current product data readily accessible
to all appropriate users throughout a manufacturing enterprise. Some of the
Company's significant customers, located worldwide, include GM, Boeing, Denso
and GE.
 
  The Company offers a full line of design, analysis and manufacturing
software products that meets the diverse needs of its customer base, which
includes a spectrum of companies from multinational corporations to small
machine shops. The Company addresses all aspects of digital product
development, including (i) product modeling, (ii) product information
management, (iii) data transfer and (iv) process re-engineering. The Company's
integrated, scalable software solutions range from Unigraphics, its high-end
MCAD software product suite for complex design, manufacture and assembly
projects, to Solid Edge, its Windows-based, easy-to-use design and drafting
product. Both Unigraphics and Solid Edge 5.0 are based on the Company's core
solid modeling kernel, Parasolid. As a result, the Company can differentiate
itself from its competitors by enabling Unigraphics and Solid Edge to
seamlessly share geometric data without the need for translation. The
Company's PDM software, IMAN, works in conjunction with both the Company's and
third parties' MCAD software to organize and manage the large volume of data
and numerous versions associated with the typical digital product model. A key
element of the Company's product development strategy is the management,
visualization and simulation of product data across the Web so that model data
may be shared among all users of the Company's MCAD and PDM products and
companion applications. In addition, the Company offers a full range of
customization, implementation and integration consulting services that enables
customers to re-engineer their methods of virtual product development by
optimizing the use of the Company's software.
 
  Through its Unigraphics, Solid Edge, Parasolid and IMAN products, the
Company served more than 4,000 customers worldwide at December 31, 1997,
comprising an aggregate of over 93,000 seats. Of these seats, there were over
49,000 Unigraphics seats, over 9,000 Solid Edge seats, over 72,000 Parasolid
seats (including over 49,000 seats embedded in Unigraphics) and over 12,000
IMAN seats. With its suite of core products, its large worldwide installed
seat base and the continuing evolution of Parasolid as a solid modeling
standard for MCAD software, the Company believes that it is well positioned to
take advantage of the MCAD market's varying demands for software
functionality, virtual product development and product data management.
 
THE MCAD SOFTWARE INDUSTRY
 
  Product development has traditionally been an iterative process of detailed
product definition, conceptual design, layout, drafting, physical prototyping,
testing, design refinement, manufacturing and assembly. Prior to the
development of computer-driven design tools, the product development cycle
demanded a long lead time since modifications to a product's design required
time intensive manual redesign at each step. CAD and CAM first became
available in the early 1970s and allowed engineers to create drawings using
computers much more quickly and accurately than by hand.
 
  The product development market is in transition. As is common in many high
technology sectors, the MCAD industry is characterized by selling prices which
have tended to decline for existing products over time
 
                                      36
<PAGE>
 
due to competition, lower marginal costs and rapid technological change. In
particular, increased competition from new sources, including the introduction
of numerous lower priced, higher volume 3-D CAD products, the
emergence of a mid-range market, and the increased penetration of niche
players into the CAM and CAE markets, has increased price pressure on MCAD
software products. Despite declining unit prices, the total size of the MCAD
global market, as measured by revenue, has increased over the past several
years.
 
  Once focused on the individual engineer's demand for MCAD functionality, the
market is now driven by the needs of the expanded enterprise of OEMs,
suppliers, partners and customers to collaborate, share data and integrate the
multiple sub-assemblies in the creation of a complex master digital model.
These needs have raised MCAD and PDM decision making to executive management
levels. However, the requirement for an enterprise level solution has not
lessened the need to provide superior functionality and engineering
capabilities to the individual user.
 
  Customer requirements for enterprise wide product development solutions are
driving a demand for scalability and redefining the historically fragmented
MCAD marketplace. Scalability is provided through a graduated series of MCAD
and PDM products that has been optimized for each level of user throughout the
customer's organization, enabling the customer to buy or lease only those
products it needs, at the most affordable prices, and to upgrade functionality
as necessary. The Company believes that this need for scalability is
contributing to the consolidation in the MCAD software industry as companies
attempt to address both the high-end and mid-range markets.
 
  The Company believes the factors dictating customer demand in this new
consolidating market are: (i) enterprise level product design and development,
(ii) affordable solid modeling, (iii) Windows orientation, (iv) software
interoperability and (v) product data management.
 
  Enterprise Level Product Design and Development. Product development
involves more than desktop product modeling. The development of a particular
product involves multiple organizations, within and outside a given
enterprise, designing a complex digital master product model, testing this
model, and then revising it or advancing the original design. While this
completely digital "master-model" approach had always been an objective,
current technological innovation and process understanding have finally
converged so that an enterprise level framework for product development can be
established with MCAD and PDM software.
 
  Affordable Solid Modeling. Solid modeling enables the user to generate more
accurate and complete product descriptions for use throughout the entire
design, manufacturing and engineering process. The availability of such solid
modeling software reinforced the distinction between high-end software, like
Unigraphics, and low-end 2-D drafting MCAD software. The decision by the
Company to license its Parasolid solid modeling kernel contributed to the
growth of a mid-range market in which advanced solid modeling functionality is
now available at affordable prices with significantly more functionality than
is available in low-end systems. Due to the affordability of mid-range MCAD
software, the Company believes the mid-range 3-D market will grow
substantially over the next several years by drawing a small percentage of
MCAD users from the high-end sector and a large percentage of users from the
low-end 2-D sector and by creating new users out of traditional "blueprint"
designers who design manually.
 
  Windows Orientation. In addition to price considerations, mid-range MCAD
products attract customers by incorporating the user-friendly Windows
interface, thereby allowing users to work without extensive or specialized
training. Not only is the Windows interface familiar, but it allows a user to
easily move from other Microsoft applications to a product modeling
application on the same operating platform and computer hardware. Today, most
mid-range MCAD offerings combine solid modeling capabilities with the Windows
user interface for both the Windows 95 and Windows NT operating systems.
 
  Interoperability. In order to design products efficiently, an enterprise's
various design teams must be able to collaborate through the exchange of
digital design data. The fact that most geometry engines are embedded within
the source code of their corresponding MCAD products has prohibited the
development of high-end and
 
                                      37
<PAGE>
 
mid-range products that share the same solid modeler. Consequently, MCAD
systems produce data files that cannot be read or used by other systems.
Product designers must therefore rely on translators to exchange data. This
data translation process is time-consuming and often results in inaccuracies
that require correction. Industry-wide efforts to solve this problem, such as
STEP (Standard for the Exchange of Product Model Data), have so far been
inadequate.
 
  Product Data Management. PDM software captures and manages all information
generated during the product development cycle, making data readily accessible
to appropriate users throughout an organization. This data capture and
management enables organizations to share information earlier in the product
development cycle, encourages data reuse and reduces engineering changes. PDM
software is beginning to extend beyond traditional database management.
Working together with MCAD software, PDM systems are enabling enterprise-wide
visualization and simulation of the virtual product. PDM systems are provided
not only by MCAD software suppliers, but also by independent PDM vendors.
 
BUSINESS STRATEGY
 
  Demand in MCAD and PDM markets is dictated by the needs of users throughout
companies of all sizes and across extended enterprises to collaborate on
virtual product development. These users often require different levels of
software functionality. The Company's strategy is to offer a variable,
customizable combination of software products and implementation and
integration services to address the product and process complexities
associated with design and assembly projects. The key elements of the
Company's strategy include:
 
  PROVIDING A FULL RANGE OF INTEGRATED SCALABLE ENTERPRISE SOLUTIONS. The
Company provides a full range of MCAD software products to meet the needs of
its customers from its high-end Unigraphics product suite to its mid-range
offering, Solid Edge. Upon the release of Solid Edge 5.0, both it and
Unigraphics will be integrated through the use of the Company's core solid
modeler, Parasolid, thereby allowing Unigraphics and Solid Edge to seamlessly
share geometric data without the need for translation. Unigraphics is scalable
with the ability to add modules or features to fit the needs of the Company's
customers, thereby reducing hardware system requirements. Solid Edge's Windows
capabilities improve design engineering productivity, shorten learning curves
and reduce training costs. The Company believes that it is well positioned
because each of its customers can buy the precise software product or products
that meet that customer's particular needs and allow its users to share data
within a single organization or throughout several organizations.
 
  ESTABLISHING PARASOLID AS A SOLID MODELING STANDARD. The Company believes
that Parasolid has emerged as the mid-range MCAD solid modeling standard while
being fully capable of addressing the demanding requirements of high-end MCAD
software. Unigraphics, the Company's high-end MCAD offering, is based on
Parasolid. The Company licenses Parasolid for incorporation into mid-range
MCAD software products such as Dassault's Solid Works and Parametric's
DesignWave. In addition, Bentley has recently converted its mid-range product,
MicroStation Modeler, to Parasolid. The Company also licenses Parasolid to
various third-party niche software application developers, who create
Parasolid-compatible specialized applications that enhance the functionality
of Unigraphics and Solid Edge. Accordingly, the Company expects that the
growing prevalence of Parasolid-based applications will make Parasolid part of
the buying criteria for MCAD software, thereby giving Unigraphics, the only
high-end MCAD product to use Parasolid, an advantage over competing high-end
products.
 
  OFFERING FULL FUNCTION PRODUCT DATA MANAGEMENT. The Company believes that
IMAN is one of the industry's most functional product data management tools
for engineering applications. IMAN captures, manages and provides enterprise-
wide access to the large volume of data generated throughout the virtual
product development cycle. IMAN's technology is scalable for use within a wide
range of customer implementations, extending from small Unigraphics-centric
design teams to globally distributed enterprises with thousands of concurrent
users across many functional areas, such as engineering, manufacturing,
marketing and procurement. The Company believes that IMAN's strengths lie in
(i) its tight integration with Unigraphics, which enables
 
                                      38
<PAGE>
 
IMAN to manage the complex interrelationships among Unigraphics files, (ii)
its variant configuration modeling, which facilitates the definition of the
modularized, rules-based views of the bill of materials that are required for
efficient manufacturing of customized products and (iii) its object-oriented
architecture, which enables designers to share data across an enterprise. A
key element of the Company's PDM strategy is utilizing Web-based technologies
to provide a common framework for the visualization, simulation and management
of product data. The Company's Web technologies provide enterprise-wide access
to the virtual product model and associated specification data, enabling
organizations outside of the traditional users of the Company's MCAD products
to utilize the data. For example, marketing departments can view virtual
products and provide immediate feedback during the product development
process.
 
  MAINTAINING TECHNOLOGICAL LEADERSHIP. The Company is focused on continually
developing and acquiring the most technologically advanced MCAD products.
Unigraphics' breadth of modeling functionality combines complex surface design
capabilities with advanced feature and solid modeling while providing some of
the most advanced CAM technology on the market today. Solid Edge, which has
pioneered advances in ease of use, was developed with native Windows
functionality, including familiar "drag and drop" features, menu driven
options, dialog boxes and on-line help, and was the first mechanical CAD
product to be certified as Microsoft Office compatible. In order to maintain
its technological leadership, the Company releases major enhancements
containing significant improvements to each of its four core products
approximately twice per year. In addition, the Company has developed UG/WAVE,
a next generation parametric approach to top-down product design that allows
"what-if" evaluations of engineering alternatives. For example, UG/WAVE allows
engineers to more efficiently evaluate at the system level the impact of
changes in wing design on the aerodynamic performance of an airplane.
 
  LEVERAGING AND EXPANDING ITS CUSTOMER BASE. The Company intends to expand
its user base by increasing sales to existing customers and to new customers
by expanding its sales force and by utilizing Web-based distribution. The
Company intends to increase the licensing of its MCAD software to its existing
customer base by offering an affordable integrated scalable product line. The
Company is targeting existing users of 2-D software by marketing the latest
version of Solid Edge as an affordable, easy-to-use 3-D product. The Company
intends to increase the size of its customer base by marketing to the
suppliers of its aerospace and automotive OEMs. The Company believes that both
of its MCAD software offerings are attractive to suppliers who seek to meet
OEM requirements because (i) Unigraphics is available in discrete modules to
allow users to purchase only the Unigraphics capabilities their businesses
require and (ii) Solid Edge is an affordable easy-to-use MCAD software package
that will have the ability to seamlessly transfer geometric data to high-end
Unigraphics users. As part of the Solid Edge Acquisition, the Company acquired
EMS, a high-end MCAD product, which had over 6,000 seats at December 31, 1997.
The Company will seek to convert EMS customers to Unigraphics or Solid Edge.
 
PRODUCTS AND SERVICES
 
 PRODUCTS
 
  The Company provides a full range of integrated, scalable software
applications, based on four core product lines: (i) Unigraphics, a suite of
high-end MCAD software for large scale Unix/Windows NT-based design,
manufacture and assembly projects, (ii) Solid Edge, a mid-range, easy-to-use
Windows MCAD modeling system for mechanical part and assembly design, (iii)
Parasolid, a solid modeling kernel, featuring an exact boundary representation
geometric modeler for high-end and mid-range MCAD, as well as commercial,
internal and data exchange applications and (iv) IMAN, a product data
management software application which organizes and manages the volumes of
data and numerous versions associated with the typical digital product model.
 
  Unigraphics. The Company believes that Unigraphics is one of the most
functional and technologically advanced MCAD systems available. Unigraphics is
used for complex design-through-manufacturing applications in the aerospace,
automotive and transportation, heavy machinery and equipment, electronics and
consumer products industries. The Unigraphics system allows a product
manufacturer to manage and coordinate the overall
 
                                      39
<PAGE>
 
process used to design the product, reduce the time and cost of the product
development cycle and organize and share product development data within a
manufacturer's organization and between a manufacturer and its OEMs and
suppliers. Its focus on mechanical engineering, including the ability to
design the entire product and its component parts, precision, high
visualization and integration with manufacturing, make it appropriate for
large and complex product development applications which require "master-
model" driven data sharing. However, it can also be scaled down, through the
use of a more streamlined software bundle, to meet the criteria of smaller,
less demanding projects.
 
  Unigraphics consists of a suite of four scalable pre-configured bundles, all
of which can be individually tailored to meet customers' feature, function and
price requirements. To further enhance scalability and customization, each
bundle is comprised of various software component modules or "building
blocks." All four bundles share and are progressively built upon certain core
modules, such as UG/Gateway, UG/Modeling (solid, feature, free-form and/or
assembly) and UG/Drafting. In addition, the Company has created over 200
specialized modules to provide specific features, which may be an included
function of a particular bundle or which may be added to a bundle as a custom
feature. All four of the bundles incorporate the same user interface and are
based upon the same Parasolid geometry engine and master-model concept, which
allows all of the bundles to interoperate and share data. These four bundles,
ranging from least to most expensive and advanced, are UG/Creator,
UG/Designer, UG/Advanced Designer and UG/Advanced Manufacturing. The Company's
scalable approach to the MCAD market allows the base purchase price of a
particular bundle to be applied to the "upgrade" of a customer's system to the
next bundle level.
 
     UG/Creator. UG/Creator is specifically designed as a mid-range companion
     product for users who work within or for an existing Unigraphics-based
     organization. Aimed at users, such as parts suppliers, who need powerful
     design functionality but do not require all of the advanced features of
     Unigraphics, UG/Creator includes a flexible solid, feature and free-form
     modeler, a sketcher and assembly modeling capability. Data created by
     UG/Creator can be moved "upstream" to any of the more advanced
     Unigraphics bundles. The other three Unigraphics bundles described below
     can fully and seamlessly share data bi-directionally "upstream" to more
     complex Unigraphics bundles and "downstream" to less complex bundles.
 
     UG/Designer. The next step in the Company's Unigraphics scale,
     UG/Designer, is a full-featured Unigraphics bundle which meets the needs
     of component modeling and drafting while also delivering complete
     interoperability with advanced Unigraphics applications. UG/Designer
     provides for curve, surface and solid geometry modeling, fully
     associative drafting and industry standard data translation
     capabilities. Because UG/Designer is fully and bi-directionally
     associative with all Unigraphics bundles, it is particularly appropriate
     for Unigraphics-based suppliers who need the ability to access and
     modify standard product designs of a particular manufacturer generated
     in Unigraphics, rather than merely access and read product data.
 
     UG/Advanced Designer. The third UG bundle, UG/Advanced Designer, is the
     Company's most advanced product modeling (versus manufacturing) tool
     set. In addition to the functions provided with UG/Designer, UG/Advanced
     Designer is equipped with freeform modeling and assembly modeling
     capabilities, user-defined features and a rapid prototyping interface.
     This bundle extends high-performance geometry creation using both
     parametric and non-parametric modeling techniques to design products
     either from the top-down or bottom-up. Where UG/Designer is ideal for
     designing component parts of products, such as the power train (the
     engine and transmission) of an automobile, UG/Advanced Designer is
     suitable for designing the entire product, such as the automobile.
 
     UG/Advanced Manufacturing. The Company's most functional and full-
     featured bundle is UG/Advanced Manufacturing, which is suitable for
     product design and large scale assembly and manufacturing. U/G Advanced
     Manufacturing includes all of the design functions of UG/Advanced
     Designer, as well as manufacturing-specific features, which allow the
     programming of multi-axis machine tools and simulation capabilities to
     actually manufacture the products designed with UG/Advanced Designer.
     Extensive editing and customization routines give each user the
     flexibility to meet his or her particular design and manufacturing
     needs.
 
                                      40
<PAGE>
 
  The Company has specifically designed Unigraphics with an open, object-
oriented software architecture. Users and third party developers can access
this open architecture through the UG/Open module, which provides a
programming framework for integrating other applications with Unigraphics. The
UG/Open framework includes an extensive set of programming tools that enable
third parties to create highly automated and sophisticated applications that
are well integrated with Unigraphics. Many of such third parties participate
in the Company's Alliance Program (as defined herein) as either "Toolkit VARs"
or business partners. See "--Sales and Marketing--Business Partnerships--
Alliance Program."
 
  The open Unigraphics architecture enables customers to achieve significant
productivity improvements by designing and integrating their own proprietary
software applications with Unigraphics. For example, Denso, the largest
supplier of automobile parts in Japan, is using UG/Open in an object oriented
programming environment to build a set of streamlined engineering applications
that extend the built-in capabilities of Unigraphics. These applications
capture Denso's proprietary engineering expertise, providing a high degree of
automation for designing such things as instrument panel components, fuel
systems, and HVAC. By incorporating specialized applications into Unigraphics,
Denso is able to improve its engineering efficiency
 
  In Version 14.0 of Unigraphics, which is expected to be released in April
1998, the Company plans to expand one of its newest modules, UG/WAVE, within
the three high-end UG bundles. UG/WAVE, a next generation parametric approach
to top-down product design, allows "what-if" evaluations of engineering
alternatives. For example, UG/WAVE allows engineers to more efficiently
evaluate at the system level the impact of design changes on such factors as
the aerodynamic performance of an airplane through changes in wing structure.
By identifying and specifying the most important variables that drive a
product's design, high level specifications can be passed down and imposed on
lower-level subassemblies, thereby automatically updating the product model.
The WAVE methodology is based on the premise that there exist not only
relationships of a "global" nature that may affect several subsystems in a
product's design, but also relationships of a more "local" nature that only
need to be dealt within a limited context of one or a few subassemblies.
UG/WAVE has the ability to segregate global relationships into an associative
"control structure," with more local relationships isolated in the components
of the assembly.
 
  In addition to incorporating software developed by the Company based on its
own core competencies, in certain cases, the Company also integrates
specialized third party components and applications into the Unigraphics
product suite. For example, Lightworks Ltd.'s software is used as the
visualization engine within Unigraphics for photo realistic rendering.
 
  Solid Edge. Solid Edge is a solid modeling system for mechanical part and
assembly design that incorporates high-performance CAD functions into an
affordable, easy-to-use software package. Solid Edge is a mid-range product
targeted towards the machinery, consumer products and consumer electronics
markets and the many users of 2-D CAD or traditional "blueprint" paper design
methods. Solid Edge supports a wide range of mechanical design applications,
including assembly design, part modeling, detailing and drafting. Solid Edge's
automatic interference detection and reporting quickly identifies assembly
problems and its concurrent assembly access allows several designers to work
on separate parts or subassemblies within the same assembly model--all with
immediate access to up-to-the-moment work of other design team members. The
Solid Edge user interface is fully Windows-compliant and task-oriented,
leading the user through a series of directed steps to accomplish the desired
task.
 
  Solid Edge was developed specifically as a native Windows application, is
available on Windows 95 or Windows NT and is well integrated into the overall
Windows environment with the standard Windows interface, including "drag and
drop" features, menu driven options, dialog boxes and on-line help. Solid Edge
is certified as "Designed for Microsoft Windows NT and Windows 95" and was the
first MCAD product to be certified as Microsoft Office compatible. The Company
believes Solid Edge's Windows capabilities improve design engineering
productivity, shorten learning curves, reduce training costs and lower system
administration overhead. The Solid Edge CAD system works well with familiar
Windows word processing, spreadsheet,
 
                                      41
<PAGE>
 
database, presentation graphics and electronic mail packages and its native
Windows orientation allows a user to bi-directionally "cut and paste" Solid
Edge data into and from these other Windows applications.
 
  Parasolid. Parasolid is an exact boundary representation geometric modeler,
supporting complex blending, freeform surfaces and feature-based solids to
serve MCAD applications. Parasolid's extensive functionality is based on a
library of routines with an object-oriented programming interface. Parasolid
provides robust solid modeling and integrated surface/sheet modeling
capabilities, including the ability to create non-manifold and cellular
bodies. It is designed for easy integration and is the only commercially
available solid modeling toolkit used in a high-end MCAD system. Parasolid is
used in Unigraphics for free-form surface construction and feature modeling as
well as all applications, including drafting, visualization, machining and
mesh generation. Parasolid will also be used as the geometric modeling kernel
in Solid Edge 5.0.
 
  The Parasolid solid modeling kernel provides the geometric engine for a
variety of MCAD applications. Its functionality includes the ability to handle
the complex blending of edges and faces and the hollowing, shelling and
creating of offset surfaces, which is important in the creation of plastic
parts. In addition, Parasolid enables a user to taper and draft angles to
calculate mold parting lines and drafts, a key aspect of die and mold design.
Finally, one of Parasolid's most unique aspects is its tolerant modeling
function which allows different tolerances to be applied to individual edges
and faces, thereby enabling the importation of less-than-perfect geometry from
other systems.
 
  The Company released Version 9.1 of Parasolid in February 1998, which
extended Parasolid's penetration in the modeling kernel market by adding
enhancements such as blending of complex vertices and extensions to hollowing
operations. These improvements are especially important for automotive and
aerospace modeling applications. The next Parasolid release, Version 10, is
scheduled for shipment in July 1998.
 
  The Company licenses Parasolid for use in such mid-range MCAD software
products as Dassault's Solid Works, Bentley's MicroStation Modeler and
Parametric's DesignWave. Parasolid is also used by many specialized software
developers to create Parasolid-compatible programs. Consequently, any MCAD
software and specialized applications that use the Parasolid engine will
become part of the "Parasolid Pipeline" and will be able to share geometric
data with other applications in the "pipeline." This seamless geometric data
sharing does not require translation of data from one program to another. The
Company has also published Parasolid's XT file format. All of these products
will be geometrically compatible with the Company's Unigraphics and Solid Edge
products, which, in turn, will be integrated with each other.
 
  IMAN. IMAN is a full-function product data management system that organizes,
manages, customizes and distributes the volumes of data and numerous versions
associated with the typical digital product model, addressing all information
in the product development environment. IMAN makes the most current product
data readily accessible to all appropriate users throughout the manufacturing
enterprise, including the engineering, purchasing and manufacturing
departments, thereby eliminating time-consuming searches and the need to re-
create data. Design, manufacturing, engineering, planning, scheduling and
other organizations can easily access and manage applicable data such as MCAD
files, bills of material, process plans, analysis models and results, audio
and video annotations, prototypes, cost structures, material specifications
and purchase orders. The Company believes that when IMAN is used in
conjunction with Unigraphics, the combination is the most tightly integrated
PDM/MCAD product on the market today. This integration supports the bi-
directional updating of a product model's structure and attributes, whether a
change to the model occurs in IMAN or Unigraphics. For example, the product
model's structure can be modified within IMAN to meet a specific customer
configuration. The updated product model can then be retrieved and validated
within Unigraphics prior to sending the customized bill of material to
manufacturing.
 
  IMAN provides configuration management, version control and other data
management capabilities through PC- and Web-based client-server architectures
communicating with remote servers. IMAN data are stored in a commercial data
base management system ("DBMS"), such as Oracle, but most of IMAN is
independent of the underlying DBMS because it creates a proprietary object-
oriented abstraction of how the data are physically
 
                                      42
<PAGE>
 
stored in the DBMS. The Unigraphics user has the option of storing files
directly in the native file system (such as UNIX or Windows) or in the IMAN
data repository.
 
  The Company is actively engaged in creating a new user interface to IMAN's
PDM engine. This new visual/virtual interface will be built upon Web-based
tools, including HTML and Java applets. It is being tailored for different
types of customers, such as "data consumers" who are mainly interested in
viewing the data, "reviewers" who need to comment on and/or approve data as
well as view it and "data authors" who generate new or substantially edit
existing data. IMAN's use of Web technology provides global access to the data
from virtually any computing platform located anywhere in the world. In turn,
IMAN's distributed object architecture provides for on-demand access to the
geographically dispersed data. This architecture provides optimal performance
while conserving global data storage requirements.
 
  The IMAN product suite consists of a set of scalable modules that can be
combined with Unigraphics modules to meet the varying needs of the Company's
customers. IMAN Base, the foundation IMAN module, maintains and secures
product data integrity by coordinating multiple concurrent user access and
preventing unauthorized data changes. All data--specifications, standard,
engineering, production and technical publications--associated with a product
and its life cycle are managed through IMAN Base. A basic IMAN license also
includes IMAN Workspace, which is an easy-to-use, graphical interface to IMAN,
and IMAN SA (System Administration), which is a utility for defining users'
roles and responsibilities and the customer's workflow procedures. Additional
IMAN modules include: (i) IMAN PSM (Product Structure Management) for managing
product configurations, (ii) IMAN Workflow for modeling business processes to
promote collaborative engineering, (iii) ITK (Integration Toolkit), an
application programming interface for integrating other applications with
IMAN, and (iv) IMAN Image Services for managing scanned images and documents
as well as multi-media data. IMAN Image Services will be a part of Version 5.0
of IMAN, which is expected to be released in May 1998.
 
  EMS. EMS is a high-end MCAD software that was acquired as part of the Solid
Edge Acquisition. The Company will continue to maintain and support the EMS
product however, it will seek to convert EMS customers to Unigraphics or Solid
Edge. There can be no assurance that such customers will switch to Unigraphics
or Solid Edge or that EMS customers will continue their current software
maintenance contracts.
 
 CONSULTING AND SUPPORT SERVICES
 
  The Company offers a full range of customization, implementation and
integration consulting services and support services to its customers. The
Company provides complete multi-platform consulting services for deployment
and support of its MCAD and PDM technologies and for their integration into a
customer's product development environment. Such services enable customers to
re-engineer their methods of virtual product development by optimizing the use
of the Company's software. The Company charges for its consulting and support
services in three different ways. Support service costs for the first 90 days
are generally included in the cost of an initial product license. Standard
ongoing support services, such as a 24-hour technical troubleshooting
telephone hotline, are included in the cost of an annual maintenance license.
Specialized consulting services or support, such as instructor-led training
courses, are charged by the man-hour or on a project basis.
 
  Customization, Implementation and Integration Consulting. The Company's
customization, implementation and integration consulting helps customers (i)
identify, acquire, customize and install hardware, software and communications
components and (ii) build and modify interfaces to allow different application
components to function together effectively. For example, Motor Coach
Industries ("Motor Coach") of Winnipeg, Manitoba, Canada launched its new
Renaissance bus using Unigraphics and IMAN software in conjunction with the
Company's consulting and implementation services. In particular, the Company's
consultants provided technical guidance and implementation and integration
expertise regarding the product information management of this large scale
project.

  Technical Support. The Company provides comprehensive technical support
services to its customers, including 24-hour a day support for certain users,
operating system support, Web tools and services and an electronic bulletin
board system, which provides electronic conferencing, electronic mail, file
transfer, call logging, and a symptom/solution database. The cost of most of
the services are built into product maintenance fees.
 
  Training. Training is designed to dramatically extend users' MCAD and PDM
skills and knowledge. The Company's training services include instructor-led
courses, computer assisted self teaching modules, on-line library, custom
course development and education, instructor placement, training assessments
and a Master Certificate Program providing a series of classes that ensure
users master the skills needed to use specific software.
 
  Data Exchange. One of the biggest obstacles companies face in realizing an
enterprise-wide product development environment is the exchange of data from
one MCAD system to another or from one media type (tapes) to another
(diskettes). To optimize data exchange, the Company offers platform transfers,
standards and premium-based translator services, media transfers, and rapid
prototyping translations.
 
  Engineering. The Company provides engineering services both on-site or at
remote locations for increased affordability. Engineering services include
modeling and drafting, analysis, data conversion and translation, numerical
control programming, and customized programming.
 
 HARDWARE
 
  The Company sells hardware to customers on an as-needed basis. The Company
purchases its hardware through EDS pursuant to purchase agreements that EDS
has with various hardware vendors. As long as EDS owns a majority interest in
the Company, the Company will be able to purchase hardware pursuant to these
purchase agreements. In 1997, approximately 25% of new software licenses sold
by the Company were bundled with hardware. The Company has relationships with
certain hardware vendors to ensure that the Company's software and the
vendors' hardware are compatible and mutually supportable. These relationships
generally provide for joint marketing and sales efforts, including joint
advertising, reselling discounts and finders fees. The Company's hardware
partners include Compaq Computer Corporation, Dell Computer Corporation,
Digital Equipment Corp., Hewlett-Packard Company, International Business
Machines Corporation, Intergraph Computer Systems, NeTpower Inc., Silicon
Graphics Inc. and Sun Microsystems Corporation. In late 1996, the Company
began deemphasizing hardware sales in order to focus on higher margin software
sales and consulting services.
 
LICENSE AGREEMENTS
 
  The Company typically charges a fixed license fee per seat for Unigraphics,
Solid Edge and IMAN based upon the number of modules and features within each
such seat. Typically, the customer receives a perpetual license for each of
these products. This license fee generally includes some short-term
maintenance and integration services as well as training services. The Company
typically provides maintenance services to its customers on an annual basis
with automatic renewals subject to the Company's or the customer's right to
terminate the maintenance upon 60 days prior notice. The Company typically
charges a maintenance fee equal to a percentage of the initial license fee,
which entitles the customer to regular product updates and enhancements and
general telephone support. The average maintenance renewal rate over the past
five years has been approximately 98%.
 
  The Company typically licenses Parasolid directly to VARs or distributors
who embed Parasolid in their own proprietary software products. These
customers typically pay an initial development license fee for the use of
Parasolid and royalty payments related to sales of their own proprietary
software products. A small number of customers license Parasolid solely for
use in their own internal operations.

CUSTOMERS
 
  The Company's customers come from a wide range of industries, including the
six key industries that are the focus of the Company's business strategy--
automotive and transportation, aerospace, consumer products, equipment and
machinery, electronics and universities. In 1997, no single customer of the
Company accounted for more than 10% of total revenues. The following table
sets forth, by strategic industry sector, certain of the Company's largest and

 AUTOMOTIVE AND TRANSPORTATION
 
  Automotive and transportation customers that use Unigraphics in their
manufacturing processes include GM, Tower Automotive and Motor Coach
Industries. In addition, many suppliers of the Company's automotive and
transportation customers use Unigraphics or Solid Edge to design parts for
these customers. Motor Coach Industries used Unigraphics in 1996 and 1997 to
virtually design the entire prototype of its Renaissance motor coach. This
virtual design process helped reduced the number of parts required from
approximately 37,000 parts to 17,000 parts and decreased the time from
inception to market by 26 months, from 60 months to 34 months. In 1995, Robert
Bosch GmbH migrated 25,000 of its motor model designs from a competing MCAD
product to the Company's Unigraphics product. These motors are often
incorporated into vehicles manufactured by GM, which is also a Unigraphics
customer.
 
  In 1996, GM entered into the EDS/GM Site License Agreement in which GM
selected Unigraphics as GM's only vehicle development software platform. By
recognizing Unigraphics as its single MCAD product development system, GM has
expressed its intent to consolidate its usage of MCAD software systems. This
consolidation will support tight integration of all phases of the GM vehicle
development processes with common data and integrated applications.
 
 AEROSPACE
 
  Unigraphics has been used by many aerospace manufacturers, including Boeing,
Israel Aircraft Industries Ltd ("Israel Aircraft"), Learjet Corporation and
Martin-Baker Aircraft Ltd, to design and manufacture various aircraft and
aircraft parts. Unigraphics was used by Boeing in the design of the F/A-18E/F
fighter aircraft and, according to internal Boeing statistics, the use of
Unigraphics for an all digital design resulted in a 75% reduction in the
number of engineering changes and a 42% reduction in the number of parts
compared to the design of the F-18 C/D unit. In 1996 and 1997, Israel Aircraft
employed Unigraphics to manufacture the wing of its Galaxy aircraft directly
from an electronic mockup of the model, without the need for any physical
mockups.
 
 CONSUMER PRODUCTS
 
  Unigraphics' breadth of functionality supports the design and manufacturing
of highly styled and complex consumer products. For this market, the
development process includes the definition of aesthetic surfaces incorporated
with the functional elements of the product. Unigraphics has proved especially
adept at integrating the aesthetic design elements with the practical and
engineering elements of products such as those from Moulinex SA. Integrated
digital mockup, photo-realistic rendering and feature-based solid modeling
have allowed enterprises to reduce their product development cycles.
 
  Solid Edge is also well suited to many design tasks within the consumer
products marketplace. Feature-based solids modeling, sheet metal, assemblies
and comprehensive drafting are employed on tasks that were once time consuming
manual design processes.
 
 EQUIPMENT AND MACHINERY
 
  Unigraphics is widely used for the manufacturing of large, complex equipment
and machinery. Its high functionality is particularly valuable to vertically
integrated equipment and machinery manufacturers seeking to satisfy all of
their MCAD needs with a single system.
 
  Solid Edge is well suited for many smaller product design tasks within the
equipment and machinery industry. Manufacturers that have typically performed
their design functions in two dimensions can migrate to Solid Edge and
incorporate the design benefits of 3-D solid modeling applications such as
mass properties analysis, interference detection, 3-D visualization and
assembly mock-ups. By performing more design steps with a 3-D MCAD system,
issues of form, fit and function can be addressed digitally, rather than with
physical prototypes, thereby reducing product development cycle times and
costs.
 
                                      46
<PAGE>
 
 ELECTRONICS
 
  Due to the short shelf life of consumer electronics products, the
electronics industry must be able to create a product, from inception to
manufacture, in a very short period of time. The Company's products allow the
mechanical design and packaging aspects of electronics products to be
considered in tandem with the actual electronics development being performed
by a different MCAD system. For example, a user of Unigraphics can design the
plastic keys of a computer keyboard at the same time the actual keyboard
electronics are being developed by another engineer on a different design
system.
 
 UNIVERSITY
 
  Through a number of programs, the Company provides its products to the
engineering departments of several universities and other educational
institutions. These programs not only provide educational opportunities for
the university students but also familiarize them with the Company's MCAD and
PDM products. The Company believes that this familiarity will encourage
engineering students to select the Company's products for their engineering
projects and further cause them to purchase or support the purchase of the
Company's products after graduation.
 
SALES AND MARKETING
 
 GENERAL
 
  The Company has a worldwide direct sales force and distributor network. The
Company's sales organization, which is divided by geographic zone, comprises
approximately 1,100 employees in 78 offices worldwide, with approximately 445
employees in the Americas, approximately 430 employees in Europe and
approximately 225 employees in the Asia/Pacific region. Each regional office
operates autonomously, but industry groups, which focus on the automotive and
transportation and aerospace industries, have been organized from a cross-
section of sales, marketing and technical personnel in each region. The
Company also has approximately 57 Unigraphics distribution partners or VARs in
21 countries covering several regions, including Eastern Europe, the Middle
East, Japan and Korea.
 
  Unigraphics and IMAN are primarily marketed and sold by the Company's direct
sales force. The high-end Unigraphics/IMAN sales cycle typically lasts from
six to eighteen months as prospective customers generally consider and test
MCAD and PDM systems from several competing vendors. The Company's sales force
is focused on increasing sales penetration at existing customers through the
sale of additional Unigraphics seats, modules and services to such customers.
Emphasis during the sales cycle is not only on product functionality, but also
on the integration of MCAD and PDM software with networking and computing
capabilities. A typical sale will include customization, implementation and
integration consulting services.
 
  While the mid-range Solid Edge sales process is generally shorter than the
Unigraphics/IMAN sales cycles, it usually involves the testing and
benchmarking of competing products. The Company intends to market and sell
Solid Edge primarily through its VARs, with support from Company-generated
marketing materials as well as shared support of industry trade shows and
seminars, advertising within trade publications and journals and direct mail
and telemarketing solicitation programs. The Company intends to strengthen its
VAR distribution network by having members of such network report directly to
senior level sales management personnel.
 
 BUSINESS PARTNERSHIPS
 
  The Company has established two business partnership programs to develop
relationships with various software developers to ensure that the Company's
software products are fully integrated with other software products in the
MCAD and PDM market.
 
  Alliance Program. The Alliance Program is an extensive and growing group of
niche software suppliers which provide specialized software applications to be
used in conjunction with Unigraphics and IMAN. The
 
                                      47
<PAGE>
 
Company has entered into joint marketing agreements with each of these
software suppliers whereby the Company and the software suppliers undertake
joint marketing and promotional efforts. The Company provides its customers
with both print and online catalogs listing the names of the Alliance Program
members and the software that each member provides. The Company believes that
the Alliance Program allows the Company's customers to capitalize on the use
of Unigraphics and IMAN. For example, Variation Systems Analysis provides a
tolerance checking ability software to be used in conjunction with Unigraphics
and Composite Design Technologies provides software that provides composite
design and manufacturing capability not available in Unigraphics.
 
  Voyager Program. The Voyager Program is a worldwide consortium of leading
software vendors offering products that complement Solid Edge's mechanical
design and drafting capabilities. It was initiated by Intergraph before the
Solid Edge Acquisition and the Company is in the process of re-signing members
to new contracts with the Company. The typical Voyager Program agreement
provides for joint marketing and promotional activities. An example of a
Voyager Program member is Structural Research and Analysis Corporation, the
developer of COSMOS/Edge, an application used to perform stress analysis
calculations in conjunction with Solid Edge.
 
RESEARCH AND DEVELOPMENT
 
  The Company's research and development staff comprises approximately 430
employees located at several offices worldwide. Members of the Company's
research and development organization are primarily located in: Cypress,
California; Huntsville, Alabama; St. Louis, Missouri; Cambridge, England; and
Cologne, Germany. The Company's current research and development staff is
composed of people with diverse backgrounds and strong industry and technical
expertise, including many senior technical and managerial people who have been
employed in the Company's development organization for fifteen years or more.
 
  During 1997, the Company spent approximately $48.0 million on software
research, development and engineering, constituting approximately 42% of its
total software revenue. The Company's software practices, architecture and
computing environment support development of software products in multiple
locations, allowing project teams to collaborate on software development
without requiring team members to be located at the same site.
 
  The Company uses a functional development process to create technologically
advanced products. This well-defined process emphasizes requirements
definition, up-front design and early detection of defects. In addition to
focusing on functionality, the Company ensures that its products are adapted
to the most popular and productive computing environments, which currently
include UNIX and Windows NT workstations employing a modern graphical user
interface based on Motif, Microsoft Windows, Web and 3-D graphics technology.
The Company's software products are designed and built using object-oriented
programming techniques.
 
  Major enhancement releases of each of the Company's four core products are
distributed approximately twice each year. The Company generally believes that
new releases contain significant improvements to the functionality of each
product as well as updates and performance improvements. Product updates are
released periodically between enhancement releases if problems are discovered
in production software. Each product enhancement release must be upwardly
compatible with the previous enhancement release and maintenance releases must
be upwardly and downwardly compatible relative to the previous enhancement
release.
 
  Reliability of the Company's products is assessed using manual testing and
the Company's suite of automated tests. Automated performance tests are also
executed for every new software build to ensure that there are no performance
or memory utilization regressions. Solid Edge's development, marketing and
support operations have been ISO 9001 certified and the Company is currently
seeking such certification for its other operations.
 
                                      48

INTELLECTUAL PROPERTY
 
  The Company relies on a combination of contracts, trade secret laws and
patents to establish and protect the proprietary rights to its technology. The
Company distributes its products under software licenses which grant customers
licenses to, rather than ownership of, the Company's products and which
contain various provisions protecting the Company's ownership and
confidentiality of the licensed technology. The source code for Unigraphics,
IMAN and Parasolid is protected as a trade secret and as an unpublished
copyright work and in certain instances with a patent. However, no assurance
can be made that others will not copy or otherwise obtain and use the
Company's products or technology without authorization. In addition, effective
copyright, trade secret and patent protection or enforcement may be
unavailable or limited in certain countries. The Company believes that, due to
the rapid technological advances within the 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 the technology.
 
  The Solid Edge Acquisition involved (i) the direct transfer to the Company
of the intellectual property rights unique to the Solid Edge and EMS products
and (ii) a perpetual, royalty-free license to the Company for certain patents,
patent applications and other intellectual property for the Solid Edge and EMS
products which is also used across other Intergraph business lines and in
other Intergraph products. The Company has the right to modify and improve all
acquired or licensed intellectual property and to own any modifications or
improvements that it makes.
 
  Unigraphics Solutions, Unigraphics, Solid Edge, Parasolid and IMAN, among
others, are trademarks that are owned by the Company.
 
COMPETITION
 
  Markets for the Company's products are highly competitive and characterized
by rapidly changing technology and evolving standards. The Company's
competitors include (i) generalist MCAD developers that offer broad-range
systems, such as Dassault, Matra Datavision, Parametric and SDRC; (ii)
specialist software developers whose product lines are focused on CAD
products, CAM products, CAE products or PDM products; and (iii) numerous
smaller niche software developers.
 
  The Company's products compete on the basis of functionality, technical
performance, price, operating system compatibility, integration, customization
capability, marketing and technical support and training. The ability of the
Company to compete successfully depends on factors both within and outside the
Company's control, including, among others, the successful and timely
development of new products, versions and features, product performance and
quality, pricing, customer service and support and both MCAD and PDM industry
and general economic trends.
 
  The Company has experienced and expects to continue to experience strong
competition. The Company's competitors may be able to respond more quickly to
new or emerging technologies and changes in customer requirements or devote
greater resources to the development, promotion and sale of their products
than the Company. Current and potential competitors may establish strategic
alliances or undertake acquisitions to increase the ability of their products
to address the needs of the Company's current and prospective customer base.
 
PROPERTIES
 
  The Company's corporate headquarters is located in St. Louis, Missouri,
where it subleases from EDS approximately 84,000 square feet of office space
for corporate general and administrative, marketing, research and development
and consulting services activities. That sublease will expire in October 2001.
The Company subleases approximately 127,000 square feet of office space in
Cypress, California from EDS, until the expiration of EDS' lease in 2002. The
Cypress facility is the Company's principal technical development and support

2001. Activities at the Cologne office include research and development,
customer training and general administration. The headquarters for Solid Edge
operations is in Huntsville, Alabama. The Company leases approximately 37,600
square feet from Intergraph, which lease will expire in December 1998. The
terms of all sublease agreements between the Company and EDS incorporate the
financial and other material terms of EDS' lease agreements for the subject
property.
 
EMPLOYEES
 
  At March 2, 1998, the Company employed over 2,000 persons who conduct
business in more than 60 offices worldwide. The Company's future success will
depend, in part, on its ability to attract, retain and motivate highly
qualified technical, engineering, marketing and management personnel. None of
the Company's U.S. employees are represented by a labor union. The Company has
never experienced a work stoppage and believes that its employee relations are
good.
 
LEGAL PROCEEDINGS
 
  The Company is from time to time involved in routine litigation incidental
to its operations. None of the litigation in which the Company is currently
involved, individually or in the aggregate, is material to the financial
condition or results of operations.
 
  To date, the Company has not experienced any litigation regarding
copyrights, trademarks, trade secrets or other intellectual property rights
alleging the infringement of such intellectual property rights of others.
Litigation alleging infringement of the intellectual property rights of others
is not uncommon in the MCAD industry and there can be no assurance that such
litigation will not be commenced in the future against the Company. If such
litigation were to be commenced against the Company, the Company could incur
significant costs with respect to the defense thereof, irrespective of the
validity or the successful assertion of such claims, which could have a
material adverse effect on the Company's results of operations or financial
condition. See "Risk Factors--Dependence on Proprietary Technology."

Moore and Mazzola, two directors who are current or former officers or
employees of EDS and two directors who will be persons who are neither
employees or officers of the Company or EDS nor directors of EDS (a "Non-
employee Director").
 
INFORMATION REGARDING THE BOARD OF DIRECTORS AND COMMITTEES
 
  The Board of Directors will be divided into three classes of directors, with
each class elected to a three-year term every third year and holding office
until their successors are elected and qualified. The class whose term of
office will expire at the Company's 1999 Annual Meeting of Stockholders will
consist of Mr. Mazzola and one other employee of EDS; the class whose term of
office will expire at the Company's 2000 Annual Meeting of Stockholders will
consist of Mr. Moore, one Non-employee Director and one other employee of EDS;
and the class whose term of office will expire at the Company's 2001 Annual
Meeting of Stockholders will consist of Mr. Fernandes and one Non-employee
Director.
 
  The Bylaws authorize the Board of Directors to designate three committees,
an Executive Committee, an Audit Committee and a Compensation Committee. The
Board of Directors will, upon consummation of the Offering, designate an
Executive Committee, an Audit Committee and a Compensation Committee. In
addition, the Board of Directors may, from time to time, designate one or more
additional committees, which shall have such duties and may exercise such
powers as are granted to it by the Board of Directors.
 
  The Executive Committee will consist of three or more members, including the
Chairman of the Board of Directors, the Vice Chairman of the Board of
Directors and the Chief Executive Officer. The Executive Committee has and may
exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the Company, with the exception of
such powers and authority as may be specifically reserved to the Board by law
or by resolution adopted by the Board of Directors.
 
  The Audit Committee, which will be composed entirely of directors who are
not employees or officers of the Company or EDS or directors of EDS, will
review and recommend the selection of independent auditors, the
 
                                      52
<PAGE>
 
fees to be paid to such auditors, the adequacy of the audit and accounting
procedures of the Company and such other matters as may be specifically
delegated to the Audit Committee by the Board of Directors. In this
connection, the Audit Committee shall, at its request, meet with
representatives of the independent auditors and with the financial officers of
the Company separately or jointly.
 
  The Compensation Committee, which will be composed entirely of Non-employee
Directors, will administer management incentive compensation plans, including
the 1988 Incentive Plan (as hereinafter defined), and will review and make
recommendations with respect to the management remuneration policies of the
Company, including salary rates and fringe benefits of elected officers, other
remuneration plans such as incentive compensation, deferred compensation and
stock option plans, directors' compensation and benefits and such other
matters as may be specifically delegated to the Compensation Committee by the
Board of Directors. In addition, the Compensation Committee will make
recommendations to the Board of Directors concerning suitable candidates for
election to the Board of Directors and with respect to assignments to
committees of the Board of Directors. In making recommendations for suitable
candidates for election to the Board of Directors, the Compensation Committee
will consider nominees for election recommended by stockholders.
 
COMPENSATION OF DIRECTORS
 
  Non-employee Directors will receive an annual retainer of $20,000 for Board
of Directors and committee service, a fee of $3,500 for serving as a committee
chairman, a fee of $1,000 for attending each meeting of the Board of Directors
or any committee thereof and reimbursement for reasonable out-of-pocket
expenses incurred in connection with attendance at such meeting of the Board
of Directors or any committee thereof.
 
  In addition, each Non-employee Director will receive, on an annual basis
pursuant to the 1998 Incentive Plan, options to purchase     shares of Class A
Common Stock at an exercise price equal to the fair market value of such
shares at the date of grant. A Non-employee Director may make an annual
election to receive, in lieu of all or any portion of the cash portion of
director's fees he or she would otherwise receive in the next year, non-
qualified stock options to purchase Common Stock in accordance with the terms
of the 1998 Incentive Plan.
 
EXECUTIVE COMPENSATION
 
  Prior to the Reorganization, all employees of the Company, including the
executive officers, were compensated by EDS. Since the Reorganization, the
executive officers and all other employees of the Company have been
compensated solely by the Company. Following the Offering, the executive
officers of the Company will continue to participate in most EDS compensation
plans other than the EDS 1996 Incentive Plan, which, with respect to future
grants to employees of the Company, will be replaced by the Company's 1998
Incentive Plan. The Company will conduct a comprehensive review of all benefit
plans during 1998 with the goal of adopting its own benefit plans over time
following the Offering.
 
  The Company's executive officers will receive annual cash compensation in
the form of a base salary and will participate in a formula-based incentive
compensation plan that is tied to the Company's financial performance. In
addition, the Company's executive officers and other key employees will be
eligible to participate in the 1998 Incentive Plan.
 
THE 1998 INCENTIVE PLAN
 
  The Board of Directors has adopted, and EDS, as the Company's sole
stockholder prior to the consummation of the Offering has approved, effective
upon the consummation of the Offering, the Unigraphics Solutions Inc. 1998
Incentive Plan (the "1998 Incentive Plan"). The description set forth below
represents a summary of the principal terms and conditions of the 1998
Incentive Plan in the form so approved and does not purport to be complete.
Such description is qualified in its entirety by reference to the 1998
Incentive Plan, a copy of which has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part.

  Any outstanding awards under the EDS 1996 Incentive Plan (or its predecessor
plan) held by executives or other employees of the Company will remain
outstanding following the closing of the Offering. However, no new awards are
expected to be granted to employees or directors of the Company under the EDS
1996 Incentive Plan. The value of outstanding awards under the EDS 1996
Incentive Plan may be taken into consideration by the Compensation Committee
in determining any awards to be granted under the Company's 1998 Incentive
Plan.
 
 GENERAL
 
  Key employees eligible for awards ("Awards") under the 1998 Incentive Plan
(the "Employees") are those that hold positions of responsibility and whose
performance can have a significant effect on the success of the Company and
its subsidiaries. The only directors eligible for automatic or elective Awards
under the 1998 Incentive Plan are Non-employee Directors.
 
  Awards to Employees under the 1998 Incentive Plan ("Employee Awards") may be
made in the form of grants of stock options ("Options"), stock appreciation
rights ("SARs"), restricted or non-restricted stock or units denominated in
stock ("Stock Awards"), cash awards ("Cash Awards"), performance awards
("Performance Awards") or any combination of the foregoing. Awards to Non-
employee Directors under the 1998 Incentive Plan ("Director Awards") will be
in the form of grants of Options.
 
  The 1998 Incentive Plan provides for Awards to be made in respect of a
maximum of     shares of Class A Common Stock, of which     shares will be
available for Director Awards and the remainder will be available for Employee
Awards. Shares of Class A Common Stock which are the subject of Awards that
are forfeited or terminated, expire unexercised, are settled in cash in lieu
of Class A Common Stock or in a manner such that all or some of the shares
covered thereby are not issued or are exchanged for Awards that do not involve
Class A Common Stock will again immediately become available for Awards under
the 1998 Incentive Plan.
 
  The 1998 Incentive Plan, as it applies to Employee Awards, but not with
respect to Non-employee Directors, will be administered by the Compensation
Committee. To the extent required pursuant to Rule 16b-3 under the Exchange
Act in order for the grant of Employee Awards to be exempt under Section 16,
the Compensation Committee will at all times consist of at least two members
of the Board of Directors who meet the requirements of the definition of "Non-
Employee Director" set forth in Rule 16b-3(b)(3)(i).
 
  Insofar as the 1998 Incentive Plan relates to Employee Awards, the
Compensation Committee will have the exclusive authority to administer the
1998 Incentive Plan and to take all actions which are specifically
contemplated thereby or are necessary or appropriate in connection with the
administration thereof. The Compensation Committee may, in its discretion,
provide for the extension of the exercisability of an Employee Award,
accelerate the vesting of exercisability of an Employee Award, eliminate or
make less restrictive any restrictions contained in an Employee Award, waive
any restriction or other provision of the 1998 Incentive Plan or in any
Employee Award or otherwise amend or modify an Employee Award in any manner
that is either (i) not adverse to the Employee holding the Employee Award or
(ii) consented to by such Employee.
 
 EMPLOYEE AWARDS
 
  The Compensation Committee will determine the type or types of Employee
Awards made under the 1998 Incentive Plan and will designate the Employees who
are to be recipients of such Awards. Each Employee Award may be embodied in an
agreement, which will contain such terms, conditions and limitations as are
determined by the Compensation Committee. Employee Awards may be granted
singly, in combination or in tandem. Employee Awards may also be made in
combination or in tandem with, in replacement of, or as alternatives to,
grants or rights under the 1998 Incentive Plan or any other employee plan of
the Company or any of its subsidiaries, including any acquired entity;
provided, however, that no Option may be issued in exchange for the
cancellation of an Option with a lower exercise price. All or part of an
Employee Award may be subject to conditions established by the Compensation
Committee, which may include continuous service with the Company and its
subsidiaries, achievement of specific business objectives, increases in
specified indices, attainment of specified growth rates and other comparable
measurements of performance.
 
                                      54
<PAGE>
 
  The types of Employee Awards that may be made under the 1998 Incentive Plan
are as follows:
 
  Options. Options are rights to purchase a specified number of shares of
Class A Common Stock at a specified price. An option granted pursuant to the
1998 Incentive Plan may consist of either an incentive stock option ("ISO")
that complies with the requirements of Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), or a non-qualified stock option
("NQSO") that does not comply with such requirements. ISOs must have an
exercise price per share that is not less than the fair market value of the
Class A Common Stock on the date of grant. NQSOs must have an exercise price
per share that is not less than, but may exceed, the fair market value of the
Class A Common Stock on the date of grant. In either case, the exercise price
must be paid in full at the time an Option is exercised in cash or, if the
Employee so elects, by means of tendering Class A Common Stock or surrendering
another Award.
 
  SARs. SARs are rights to receive a payment, in cash or Class A Common Stock,
equal to the excess of the fair market value or other specified valuation of a
specified number of shares of Class A Common Stock on the date the rights are
exercised over a specified strike price. An SAR may be granted under the 1998
Incentive Plan to the holder of an Option with respect to all or a portion of
the shares of Class A Common Stock subject to such Option or may be granted
separately. The terms, conditions and limitations applicable to any SARs,
including the term of any SARs and the date or dates upon which they become
exercisable, will be determined by the Compensation Committee.
 
  Stock Awards. Stock Awards consist of restricted and non-restricted grants
of Class A Common Stock or units denominated in Class A Common Stock. The
terms, conditions and limitations applicable to any Stock Awards will be
determined by the Compensation Committee. The Compensation Committee may
remove any restrictions on Stock Awards, at its discretion. Without limiting
the foregoing, rights to dividends or dividend equivalents may be extended to
and made part of any Stock Award in the discretion of the Compensation
Committee.
 
  Cash Awards. Cash Awards consist of grants denominated in cash. The terms,
conditions and limitations applicable to any Cash Awards will be determined by
the Compensation Committee.
 
  Performance Awards. Performance Awards consist of grants made to an Employee
subject to the attainment of one or more performance goals. A Performance
Award will be paid, vested or otherwise deliverable solely upon the attainment
of one or more pre-established, objective performance goals established by the
Compensation Committee prior to the earlier of (i) 90 days after the
commencement of the period of service to which the performance goals relate
and (ii) the elapse of 25% of the period of service, and in any event while
the outcome is substantially uncertain. A performance goal may be based upon
one or more business criteria that apply to the Employee, one or more business
units of the Company or the Company as a whole, and may include any of the
following: revenues, net income, stock price, market share, earnings per
share, return on equity, return on assets or decrease in costs. Subject to the
foregoing, the terms, conditions and limitations applicable to any Performance
Awards will be determined by the Compensation Committee.
 
 DIRECTOR AWARDS
 
  Under the 1998 Incentive Plan, each Non-employee Director will receive the
Awards described below, which will be granted either automatically or at the
option of the Non-employee Director in lieu of director's fees.
 
  Non-employee Director Options. On the date of his or her initial election to
the Board of Directors, each Non-employee Director will automatically receive
a grant of NQSOs that provide for the purchase of    shares of Class A Common
Stock. In addition, on the first business day of the month following the date
on which each annual meeting of the stockholders of the Company is held (each,
an "Annual Director Award Date"), each Non-employee Director will
automatically receive a grant of NQSOs that provide for the purchase of
shares of Class A Common Stock. A Non-employee Director who is elected
otherwise than
 
                                      55
<PAGE>
 
by election at an annual meeting of stockholders of the Company, and other
than those elected immediately following the Offering, will automatically
receive, on the date of his or her election, a grant of NQSOs that provides
for the purchase of a number of shares of Class A Common Stock equal to the
product of (i)     and (ii) a fraction the numerator of which is the number of
days between the election of such Non-employee Director and the next scheduled
Annual Director Award Date and the denominator of which is 365. The term of
the NQSOs granted to Non-employee Directors will be for a period of ten years
from the date of grant. The exercise price of such NQSOs will be equal to the
fair market value of the Class A Common Stock on the date of grant. Such
exercise price must be paid in full in cash at the time an NQSO is exercised.
All NQSOs granted to Non-employee Directors under the 1998 Incentive Plan will
become exercisable in increments of one-third of the total number of shares of
Class A Common Stock that are subject thereto on the first, second and third
anniversaries of the date of grant. All unvested NQSOs granted to a Non-
employee Director will be forfeited if the Non-employee Director resigns from
the Board of Directors without the consent of a majority of the other
directors.
 
  In addition a Non-employee Director may make an annual election to receive,
in lieu of all or any portion of the director's fees he or she would otherwise
receive in the next year (including both annual retainer and meeting fees), a
number of NQSOs equal to the product of (x) three times (y) a fraction the
numerator of which is equal to the dollar amount of fees the Non-employee
Director elects to forego in the next year in exchange for NQSOs and the
denominator of which is equal to the fair market value of Class A Common Stock
on the date of the election. The terms of the NQSOs received by a Non-employee
Director pursuant to such election will be the same as those of the NQSOs
automatically granted as described above.
 
 OTHER PROVISIONS
 
  The Board of Directors may amend, modify, suspend or terminate the 1998
Incentive Plan for the purpose of addressing any changes in legal requirements
or for any other purpose permitted by law, except that (i) no amendment that
would impair the rights of any Employee or Non-employee Director with respect
to any Award may be made without the consent of such Employee or Non-employee
Director and (ii) no amendment requiring stockholder approval in accordance
with Rule 16b-3 under the Exchange Act will be effective until such approval
has been obtained.
 
  In the event of any subdivision or consolidation of outstanding shares of
Class A Common Stock, declaration of a stock dividend payable in shares of
Class A Common Stock or other stock split, the 1998 Incentive Plan provides
for the Compensation Committee to make appropriate adjustments to (i) the
number of shares of Class A Common Stock reserved under the 1998 Incentive
Plan, (ii) the number of shares of Class A Common Stock covered by outstanding
Awards in the form of Class A Common Stock or units denominated in Class A
Common Stock, (iii) the exercise or other price in respect of such Awards,
(iv) the appropriate fair market value and other price determinations for
Awards in order to reflect such transactions, (v) the number of shares of
Class A Common Stock covered by Options automatically granted to Non-employee
Directors, (vi) the number of shares covered by restricted Stock Awards
automatically granted to Non-employee Directors and (vii) the limitations set
forth in the 1998 Incentive Plan regarding the number of Awards which may be
made to any Employee in a given year. Furthermore, in the event of any other
recapitalization or capital reorganization of the Company, any consolidation
or merger of the Company with another corporation or entity, the adoption by
the Company of any plan of exchange affecting the Class A Common Stock or any
distribution to holders of Class A Common Stock of securities or property
(other than normal cash dividends or stock dividends), the Board of Directors
will make appropriate adjustments to the amounts or other items referred to in
clauses (ii), (iii), (iv), (v), (vi) and (vii) above to give effect to such
transactions, but only to the extent necessary to maintain the proportionate
interest of the holders of the Awards and to preserve, without exceeding, the
value thereof.
 
 ANTICIPATED OPTION AND SAR GRANTS TO THE EXECUTIVE OFFICERS FOR 1998
 
  On the date of the consummation of the Offering, the Company will make one-
time grants of an aggregate of    NQSOs to certain key employees of the

THE EDS RETIREMENT PLAN
 
  Following the closing of the Offering, the Company intends to fully review
its employee benefit packages to seek to better align its benefit packages
with those of its competitors. Prior to the completion of such review, the
Company's employees will continue to participate in substantially all EDS
benefit plans to the extent permitted by law, including the Electronic Data
Systems Corporation Retirement Plan (the "EDS Retirement Plan"). All of the
Company's employees who have at least one year of Service and are at least 18
years of age are eligible to participate in the EDS Retirement Plan.

  As of December 31, 1997, the final average earnings for the highest five
consecutive years over the last 10-year period and the eligible years of
credited service for each of the named executive officers was as follows: Mr.
Mazzola, $249,972--6 years; Mr. Affuso, $176,445--13 years; Mr. Kruse,
$178,382--6 years; Mr. Davidson, $183,580--6 years; Mr. Duncan, $121,506--6
years. The annual base salary for the most recent year considered in the
calculation of such average annual base salary is set forth in the Summary
Compensation Table set forth below under the column labeled "Salary."
 
  "Earnings" under the EDS Retirement Plan generally refer to total annual
cash compensation (up to $160,000 for 1997 as limited by the Code) for
services rendered to the Company and its participating subsidiaries, together
with any salary reduction contributions to the EDS Deferred Compensation Plan,
and shall exclude extraordinary compensation (such as overseas living
allowances, relocation allowances and benefits under any employee benefit
plan, such as the 1998 Stock Incentive Plan). Benefits under the EDS
Retirement Plan generally equal (i) 55% of the participant's final average
earnings (based on the highest five consecutive years of includible earnings
within the last ten years of employment), less the maximum offset allowance
that can be deducted from final average earnings as determined under the Code,
multiplied by (ii) the participant's years of credited benefit service (not to
exceed 30), divided by 30. Benefits are payable in the form of a single or
joint survivor life annuity, unless otherwise elected.

EDS STOCK PURCHASE PLAN
 
  Under the terms of the Management Services Agreement entered into between
the Company and EDS, employees of the Company will be permitted to continue
participation in the Electronic Data Systems Corporation Stock Purchase Plan
(the "EDS Stock Purchase Plan") to the extent they are currently permitted by
law to participate. The Company will reimburse EDS for the difference between
the price paid for a share of common stock, par value $.01 per share ("EDS
Common Stock"), of EDS pursuant to the EDS Stock Purchase Plan and the fair
market value of such share of EDS Common Stock. In connection with its overall
review of the Company's benefit packages to occur following the closing of the
Offering, EDS or the Company may determine to discontinue the Company's
participation in such plan.
 
  The EDS Stock Purchase Plan is intended to qualify as an "employee stock
purchase plan" under Section 423 of the Code. All full-time employees of EDS
and certain subsidiaries are eligible to participate in the EDS Stock Purchase
Plan.
 
  All eligible employees who enroll in an offering receive options to purchase
shares of EDS Common Stock at a price that is not less than the lesser of (i)
85% of the fair market value of the stock on the offering date or (ii) an
amount which under the terms of the offering is not less than 85% of such fair
market value at the time the right to purchase is exercised. Shares of EDS
Common Stock purchased under the EDS Stock Purchase Plan may not be sold or
transferred within two years of the date of purchase unless they are first
offered to EDS at the lesser of (i) the price originally paid for the shares
or (ii) the fair market value per share of EDS Common Stock on the date the
shares are offered to EDS.
 
EMPLOYMENT AGREEMENTS
 
  The Company plans to enter into employment agreements with Messrs. Mazzola,
Affuso, Barnett, Davidson, Duncan and Kruse prior to the consummation of the
Offering.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Compensation information with respect to the named executives for 1997
reflects compensation earned prior to the effectiveness of the Reorganization
while the business of the Company was operated within several business units
of EDS. Accordingly, the Company did not have a compensation committee during
1997.
 
INDEMNIFICATION AGREEMENTS
 
  The Company has entered into Indemnification Agreements (the
"Indemnification Agreements") with certain of its directors and executive
officers (the "Indemnitees"), a form of which is filed with the Commission as
an exhibit to the Registration Statement of which this Prospectus is a part.
Under the terms of the Indemnification Agreements, the Company has generally
agreed to indemnify, and advance expenses to, each Indemnitee to the fullest
extent permitted by applicable law on the date of such agreements and to such
greater extent as applicable law may thereafter permit. In addition, the
Indemnification Agreements contain specific provisions pursuant to which the
Company has agreed to indemnify each Indemnitee (i) if such person is, by
reason of his or her status as a director, nominee for director, officer,
agent or fiduciary of the Company or of any other corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise with which
such person was serving at the request of the Company (any such status being
hereinafter referred to as a "Corporate Status"), made or threatened to be
made a party to any threatened, pending or completed action, suit,
arbitration, alternative dispute resolution mechanism, investigation or other
proceeding (each, a "Proceeding"), other than a Proceeding by or in the right
of the Company, (ii) if such person is, by reason of his or her Corporate
Status, made or threatened to be made a party to any Proceeding brought by or
in the right of the Company to procure a judgment in its favor, except that no
indemnification shall be made in respect of any claim, issue or matter in such
Proceeding as to which such Indemnitee shall have been adjudged to be liable
to the Company if applicable law prohibits such indemnification (unless and
only to the extent that a court shall otherwise determine), (iii) against
expenses actually and reasonably incurred by such person or on his or her
behalf in connection with any
 
                                      58
<PAGE>
 
Proceeding to which such Indemnitee was or is a party by reason of his or her
Corporate Status and in which such Indemnitee is successful, on the merits or
otherwise, (iv) against expenses actually and reasonably incurred by such
person or on his or her behalf in connection with a Proceeding to the extent
that such Indemnitee is, by reason of his or her Corporate Status, a witness
or otherwise participates in any Proceeding at a time when such person is not
a party in the Proceeding, and (v) against expenses actually and reasonably
incurred by such person in any judicial adjudication of or any award in
arbitration to enforce his or her rights under the Indemnification Agreements.
 
  Furthermore, under the terms of the Indemnification Agreements, the Company
has agreed to pay all reasonable expenses incurred by or on behalf of an
Indemnitee in connection with any Proceeding, whether brought by or in the
right of the Company or otherwise, in advance of any determination with
respect to entitlement to indemnification and within 15 days after the receipt
by the Company of a written request from such Indemnitee for such payment. In
the Indemnification Agreements, each Indemnitee has agreed that he or she will
reimburse and repay the Company for any expenses so advanced to the extent
that it shall ultimately be determined that he or she is not entitled to be
indemnified by the Company against such expenses.
 
  The Indemnification Agreements also include provisions that specify the
procedures and presumptions which are to be employed to determine whether an
Indemnitee is entitled to indemnification thereunder. In some cases, the
nature of the procedures specified in the Indemnification Agreements varies
depending on whether there has occurred a "Change in Control" (as defined in
the Indemnification Agreements) of the Company.

                RELATIONSHIP WITH EDS AND CERTAIN TRANSACTIONS
 
FORMATION OF THE COMPANY; INDEBTEDNESS TO EDS
 
  The Company was formed on October 2, 1997 and, pursuant to the
Reorganization, became the successor to the Unigraphics MCAD business of EDS
effective as of January 1, 1998.
 
  In connection with the Solid Edge Acquisition, on March 2, 1998 the Company
borrowed $107 million from EDS pursuant to the Intercompany Credit Agreement.
See "--Contractual Arrangements--Intercompany Credit Agreement." In addition,
effective March 6, 1998 the Company issued to EDS as a dividend the
Intercompany Note in the principal amount of $73 million. The Intercompany
Note bears interest, payable semiannually, at the one-month LIBID minus 0.5%,
and matures on March 6, 2001. The amounts advanced by EDS to the Company under
the Intercompany Credit Agreement in respect of the Solid Edge Acquisition, as
well as a portion of the amount outstanding under the Intercompany Note, will
be repaid to EDS with the net proceeds of the Offering. See "Use of Proceeds."
 
  Also in connection with the Reorganization, the Company and EDS entered into
an Intercompany Agreement (the "Intercompany Agreement") pursuant to which
each party indemnified the other for certain obligations relating to the
Reorganization. Pursuant to the Intercompany Agreement, the Company
indemnified EDS for liabilities assumed in the Reorganization and against
third party claims asserted against EDS as a result of EDS' prior ownership of
assets or operation of businesses contributed to the Company and for losses
arising from or in connection with the Company's lease of property from EDS.
In exchange, EDS indemnified the Company for specified liabilities retained by
it in the Reorganization, against third party claims against the Company
relating to EDS' businesses and asserted against the Company as a result of
the ownership or possession by EDS prior to the Reorganization of any asset
contributed to the Company in the Reorganization.
 
COMMON STOCK OWNERSHIP
 
  EDS currently owns all of the outstanding capital stock of the Company. Upon
completion of the Offering, EDS will own 100% of the Company's outstanding
Class B Common Stock, which will represent approximately   % of the combined
voting power of the Company's outstanding Common Stock (approximately   % if
the U.S. Underwriters' over-allotment option is exercised in full). The Class
A Common Stock and Class B Common Stock will be the only voting stock of the
Company following the Offering. As long as EDS continues to beneficially own a
majority of the combined voting power of the Common Stock, it will have the
ability to elect all of the members of the Board of Directors and control the
management and affairs of the Company, including any determinations with
respect to mergers or other business combinations involving the Company, the
acquisition or disposition of assets by the Company, the incurrence of
indebtedness by the Company, the issuance of any additional Common Stock or
other equity securities or the declaration and payment of any dividends on the
Common Stock. In addition, EDS will be able to determine the outcome of any
matter submitted to a vote of the Company's stockholders for approval and to
cause or prevent a change in control.
 
  Conflicts of interest may arise between the Company and EDS in a number of
areas relating to their past and ongoing relationships, including the nature
and quality of services rendered by EDS and its affiliates to the Company, the
performance by the Company and EDS of their obligations under the GM
Subcontract, potential competitive business activities, tax and employee
benefit matters, indemnity agreements, registration rights, sales or
distributions by EDS of all or any portion of its ownership interest in the
Company or EDS' ability to control the management and affairs of the Company.
There can be no assurance that EDS and the Company will be able to resolve any
potential conflict or that, if resolved, the Company would not have received a
more favorable resolution if it were dealing with an unaffiliated party. In
addition, certain of the Affiliate Agreements contain specific procedures for
resolving disputes between the Company and EDS with respect to the subject
matter of those agreements. There can be no assurance that more favorable
results to the Company would not be obtained under different procedures.
 
                                      61
<PAGE>
 
CHARTER PROVISIONS
 
  The Certificate of Incorporation of the Company provides that any amendment
or termination of any agreement or arrangement, or any new agreement or
arrangement, between the Company and EDS or its affiliates effected with the
approval of a majority of the Company's directors who are Disinterested
Directors or consistent with guidelines or standards approved by the
Disinterested Directors, or approved by the holders of a majority of the
Company's outstanding voting stock (not including that owned by EDS) shall be
deemed fair to the Company and its stockholders. If such approval is not
obtained, however, no presumption shall arise that such amendment or
termination (or new agreement) is not fair to the Company and its
stockholders. The Certificate of Incorporation also contains provisions
allocating corporate opportunities that may be suitable for both EDS and the
Company. See "Description of Capital Stock--Certificate of Incorporation and
Bylaw Provisions."
 
CONTRACTUAL ARRANGEMENTS
 
  In addition to the Intercompany Agreement, the Company entered into the
following agreements with EDS or affiliates of EDS (together with the
Intercompany Agreement, the "Affiliate Agreements").
 
 MANAGEMENT SERVICES AGREEMENT
 
  The Company and EDS are parties to the Management Services Agreement, dated
effective as of January 1, 1998 (the "Management Services Agreement"),
pursuant to which EDS performs various management services for the Company,
including treasury, risk management, tax and similar administrative services.
The Company expects to pay EDS approximately $8.5 million for such services in
1998, subject to adjustment based on service levels and negotiated prices.
This agreement provides for the payments of fees to EDS for such services,
either on a fixed price or usage basis, which fees are generally designed to
approximate EDS' cost of providing the services, as well as a fixed fee equal
to 0.5% of the Company's total revenues. The Management Services Agreement
will expire on December 31, 2002 unless terminated earlier by either party if
EDS and the Company are no longer under common control. Except for certain tax
and treasury management services relating to consolidated operations or
corporate policy of EDS, which the Company is required to purchase during the
term of the Management Services Agreement, the Company or EDS may terminate
any service on or after January 1, 2000 with prior notice of not less than
five months. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Overview."
 
 TAX SHARING AGREEMENT
 
  The Company and EDS have entered into the Tax Sharing Agreement, dated
effective as of January 1, 1998 (the "Tax Sharing Agreement"), which provides
for the allocation of tax liabilities during the tax periods the Company is
part of consolidated federal, state and local income tax returns filed by EDS.
In addition, the Tax Sharing Agreement sets out certain benefits and
obligations of the Company and EDS for tax matters relating to periods before
the Reorganization and for certain benefits and obligations that would affect
the Company or EDS in the future if the Company ceased to be a member of EDS'
consolidated group for federal income tax purposes. The Tax Sharing Agreement
generally requires the Company to pay to EDS the amount of federal, state and
local income taxes that the Company would have been required to pay had the
Company and its subsidiaries filed their own tax return or returns and not
been included in the EDS consolidated group. The Company is jointly and
severally liable for the federal income tax of EDS and the other companies
included in the consolidated return for all periods in which the Company is
included in the EDS consolidated group. EDS has agreed, however, to indemnify
the Company for any liability for taxes reported or required to be reported on
a consolidated return.
 
  Except for certain items specified in the Tax Sharing Agreement, EDS
generally retains any potential tax benefit carryforwards, and remains
obligated to pay all taxes, attributable to periods before the Reorganization.
 
                                      62
<PAGE>
 
 INTERCOMPANY CREDIT AGREEMENT
 
  In order to allow EDS to manage efficiently the cash and cash needs of its
subsidiaries, the Company and EDS are parties to the Intercompany Credit
Agreement, effective as of January 1, 1998 (the "Intercompany Credit
Agreement"), pursuant to which the Company is required to borrow from EDS, and
EDS is required to lend to the Company, amounts required by the Company to
fund its daily cash requirements. In addition, EDS has made an advance to the
Company under the Intercompany Credit Agreement in the amount of $107 million
in connection with the Solid Edge Acquisition, which advance will be repaid
upon consummation of the Offering. The maximum amount that the Company may
borrow at any time from EDS under the Intercompany Credit Agreement (together
with the other non-U.S. credit agreements referred to below) is $177 million
at any time prior to the consummation of the Offering or $70 million at any
time thereafter. Also, under the Intercompany Credit Agreement, the Company is
required to lend to EDS all excess cash of the Company. The interest rate to
be charged to the Company is the sum of the one-month LIBOR plus 0.5%. The
interest rate to be charged to EDS is the one-month LIBID minus 0.5%. On any
business day that the Company has excess cash available, it must use that cash
to repay any outstanding loans it has under the Intercompany Credit Agreement
or make an advance to EDS if no loans are outstanding. The Intercompany Credit
Agreement will terminate on December 31, 2002, unless earlier terminated at
the election of one of the parties upon the occurrence of certain events,
including the termination of the Management Services Agreement or the
cessation of EDS' beneficial ownership of 50% or more of the capital stock of
the Company. In addition to the Intercompany Credit Agreement between the
Company and EDS, EDS Finance plc, a wholly-owned subsidiary of EDS, has
entered into or will enter into credit agreements with substantially all non-
U.S. subsidiaries of the Company, which credit agreements will have terms
similar to the Intercompany Credit Agreement.
 
 GM SUBCONTRACT
 
  The Company and EDS have entered into the GM Subcontract dated effective
January 1, 1998 which sets forth the framework for the provisions of the
Company's products and services to GM. The GM Subcontract provides that all
products and services of the Company which are "in-scope" for purposes of the
EDS/GM MSA will continue to be provided directly by EDS to GM, with the
Company providing such products and services as a subcontractor to EDS and
receiving the revenues attributable to such products and services. "In-scope"
services include the EDS/GM Site License Agreement and any successor
agreement. The GM Subcontract further provides that products and services
which are not "in-scope" under the EDS/GM MSA may be provided directly to GM
by the Company. The GM Subcontract sets forth a framework for cooperation
between EDS and the Company in connection with providing services to GM and
provides for the operation and the representation of EDS and Company with the
goal of furthering both EDS' and the Company's relationships with GM in a

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of   shares of Class A
Common Stock,     shares of Class B Common Stock and     shares of Preferred
Stock. None of the Class A Common Stock or Preferred Stock is outstanding as
of the date hereof. Of the     shares of Class A Common Stock authorized,
are being offered in the Offering (    shares if the U.S. Underwriters' over-
allotment option is exercised in full),    shares will be reserved for
issuance upon conversion of Class B Common Stock into Class A Common Stock and
    shares have been reserved for issuance pursuant to the 1998 Incentive
Plan. See "Management--Compensation of Directors" and "Management--1998
Incentive Plan." Of the     shares of Class B Common Stock authorized,
will be outstanding and held by EDS upon consummation of the Offering. The
following summary description of the capital stock of the Company is qualified
by reference to the Certificate of Incorporation and Bylaws of the Company,
copies of which are filed as exhibits to the Registration Statement.
 
COMMON STOCK
 
 VOTING RIGHTS
 
  The holders of Class A Common Stock and Class B Common Stock generally have
identical rights except that holders of Class A Common Stock are entitled to
one vote per share while holders of Class B Common Stock are entitled to 10
votes per share on all matters to be voted on by stockholders. Holders of
shares of Class A Common Stock and Class B Common Stock are not entitled to
cumulate their votes in the election of directors. Generally, all matters to
be voted on by stockholders must be approved by a majority (or, in the case of
election of directors, by a plurality) of the votes entitled to be cast by all
shares of Class A Common Stock and Class B Common Stock present in person or
represented by proxy, voting together as a single class, subject to any voting
rights granted to holders of any Preferred Stock. Except as otherwise provided
by law, and subject to any voting rights granted to holders of any outstanding
Preferred Stock, amendments to the Company's Certificate of Incorporation
generally must be approved by a majority of the combined voting power of all
Class A Common Stock and Class B Common Stock voting together as a single
class. However, amendments to the Company's Certificate of Incorporation that
would alter or change the powers, preferences or special rights of the Class A
Common Stock or the Class B Common Stock so as to affect them adversely also
must be approved by a majority of the votes entitled to be cast by the holders
of the shares affected by the amendment, voting as a separate class.
Notwithstanding the foregoing, any amendment to the Company's Certificate of
Incorporation to increase the authorized shares of any class or authorize the
creation, authorization or issuance of any securities convertible into, or
warrants or options to acquire, shares of any such class or classes of stock
shall be approved by the affirmative vote of the holders of a majority of the
Common Stock, voting together as a single class.
 
  Effective as of the first time at which EDS shall cease to be the beneficial
owner of an aggregate of at least a majority of the voting power of the Voting
Stock (as defined herein) of the Company then outstanding (the "Trigger
Date"), amendments to certain provisions of the Certificate of Incorporation
will require the approval of 80% of the combined voting power of all Class A
Common Stock and Class B Common Stock, voting together as a single class.
 
 DIVIDENDS
 
  Holders of Class A Common Stock and Class B Common Stock will share in an
equal amount per share in any dividend declared by the Board of Directors,
subject to any preferential rights of any outstanding Preferred Stock.
Dividends consisting of shares of Class A Common Stock and Class B Common
Stock may be paid only as follows: (i) shares of Class A Common Stock may be
paid only to holders of Class A Common Stock and shares of Class B Common
Stock may be paid only to holders of Class B Common Stock and (ii) shares
shall be paid proportionally with respect to each outstanding share of Class A
Common Stock and Class B Common Stock.
 
 
                                      64
<PAGE>
 
 CONVERSION
 
  Each share of Class B Common Stock is convertible while held by EDS or any
of its subsidiaries at such holder's option into one share of Class A Common
Stock. Following the occurrence of a Tax-Free Spin-Off (as hereinafter
defined), if any, shares of Class B Common Stock shall not be convertible into
shares of Class A Common Stock at the option of the holder thereof.
 
  Except as provided below, prior to any Tax-Free Spin-Off, any shares of
Class B Common Stock transferred to a person other than EDS or any of its
subsidiaries or the Class B Transferee (as defined below) shall automatically
convert to shares of Class A Common Stock upon such disposition. Shares of
Class B Common Stock representing more than a 50% economic interest in the
Company transferred by EDS or any of its subsidiaries in a single transaction
to one unrelated person (the "Class B Transferee") or any subsidiary of the
Class B Transferee shall not automatically convert to shares of Class A Common
Stock upon such disposition. Any shares of Class B Common Stock retained by
EDS or its subsidiaries following any such transfer of shares of Class B
Common Stock to the Class B Transferee shall automatically convert into shares
of Class A Common Stock upon such transfer. Shares of Class B Common Stock
transferred to stockholders of EDS or stockholders of the Class B Transferee
in a transaction intended to be on a tax-free basis (a "Tax-Free Spin-Off")
under the Code shall not convert to shares of Class A Common Stock upon the
occurrence of such Tax-Free Spin-Off.
 
  Following a Tax-Free Spin-Off, shares of Class B Common Stock shall be
transferred as Class B Common Stock, subject to applicable laws; provided,
however, that shares of Class B Common Stock shall automatically convert into
shares of Class A Common Stock on the fifth anniversary of the Tax-Free Spin-
Off, unless prior to such Tax-Free Spin-Off, EDS, or the Class B Transferee,
as the case may be, delivers to the Company an opinion of counsel reasonably
satisfactory to the Company to the effect that such conversion could adversely
affect the ability of EDS, or the Class B Transferee, as the case may be, to
obtain a favorable ruling from the Internal Revenue Service that the transfer
would be a Tax-Free Spin-Off. If such an opinion is received, approval of such
conversion shall be submitted to a vote of the holders of the Common Stock as
soon as practicable after the fifth anniversary of the Tax-Free Spin-Off,
unless EDS or the Class B Transferee, as the case may be, delivers to the
Company an opinion of counsel reasonably satisfactory to the Company prior to
such anniversary that such vote could adversely affect the status of the Tax-
Free Spin-Off, including the ability to obtain a favorable ruling from the
Internal Revenue Service; if such opinion is so delivered, such vote shall not
be held. Approval of such conversion will require the affirmative vote of the
holders of a majority of the shares of both Class A Common Stock and Class B
Common Stock present and voting, voting together as a single class, with each
share entitled to one vote for such purpose. No assurance can be given that
such conversion would be consummated. The requirement to submit such
conversion to a vote of the holders of the Common Stock is intended to ensure
that tax-free treatment of the Tax-Free Spin-Off is preserved should the
Internal Revenue Service challenge such automatic conversion as violating the
80% vote requirement currently required by the Code for a tax-free spin-off.
 
 OTHER RIGHTS
 
  On liquidation, dissolution or winding up of the Company, after payment in
full of the amounts required to be paid to holders of Preferred Stock, if any,
all holders of Common Stock, regardless of class, are entitled to share
ratably in any assets available for distribution to holders of shares of
Common Stock.
 
  No shares of either class of Common Stock are subject to redemption or have
preemptive rights to purchase additional shares of Common Stock.
 
  Upon consummation of the Offering, all the outstanding shares of Class A
Common Stock and Class B Common Stock will be legally issued, fully paid and
nonassessable.
 
                                      65
<PAGE>
 
PREFERRED STOCK
 
  As of the date of this Prospectus, no shares of Preferred Stock are
outstanding. The Board of Directors may authorize the issuance of Preferred
Stock in one or more series and may determine, with respect to any such
series, the designations, powers, preferences and rights of such series, and
the qualifications, limitations and restrictions thereof, including (i) the
designation of the series; (ii) the number of shares of the series, which
number the Board of Directors may thereafter (except where otherwise provided
in the designations for such series) increase or decrease (but not below the
number of shares of such series then outstanding); (iii) whether dividends, if
any, will be cumulative or noncumulative and the dividend rate of the series;
(iv) the conditions upon which and the dates at which dividends, if any, will
be payable, and the relation which such dividends, if any, shall bear to the
dividends payable on any other class or classes of stock; (v) the redemption
rights and price or prices, if any, for shares of the series; (vi) the terms
and amounts of any sinking fund provided for the purchase or redemption of
shares of the series; (vii) the amounts payable on and the preferences, if
any, of shares of the series, in the event of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company; (viii)
whether the shares of the series will be convertible into shares of any other
class or series, or any other security, of the Company or any other
corporation, and, if so, the specification of such other class or series or
such other security, the conversion price or prices or rate or rates, any
adjustments thereof, the date or dates as of which such shares shall be
convertible and all other terms and conditions upon which such conversion may
be made; (ix) restrictions on the issuance of shares of the same series or of
any other class or series; and (x) the voting rights, if any, of the holders
of shares of such series.
 
  The Company believes that the ability of the Board of Directors to issue one
or more series of Preferred Stock will provide the Company with flexibility in
structuring possible future financings and acquisitions and in meeting other
corporate needs that might arise. The authorized shares of Preferred Stock
will be available for issuance without further action by the Company's
stockholders, unless such action is required by applicable law or the rules of
any stock exchange or automated quotation system on which the Company's
securities may be listed or traded.
 
  Although the Board of Directors has no intention at the present time of
doing so, it could issue a series of Preferred Stock that could, depending on
the terms of such series, impede the completion of a merger, tender offer or
other takeover attempt. The Board of Directors will make any determination to
issue such shares based on its judgment as to the best interests of the
Company and its stockholders. The Board of Directors, in so acting, could
issue Preferred Stock having terms that could discourage a potential acquiror
from making, without first negotiating with the Board of Directors, an
acquisition attempt through which such acquiror may be able to change the
composition of the Board of Directors, including a tender offer or other
transaction that some, or a majority, of the Company's stockholders might
believe to be in their best interests or in which stockholders might receive a
premium for their stock over the then current market price of such stock.
 
BUSINESS COMBINATION STATUTE
 
  As a corporation organized under the laws of the State of Delaware, the
Company will be subject to Section 203 of the DGCL, which restricts certain
business combinations between the Company and an "interested stockholder" (in
general, a stockholder owning 15% or more of the Company's outstanding voting
stock) or its affiliates or associates for a period of three years following
the time that the stockholder becomes an "interested stockholder." The
restrictions do not apply if (i) prior to an interested stockholder becoming
such, the Board of Directors approved either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder, (ii) upon consummation of the transaction which resulted in any
person becoming an interested stockholder, such interested stockholder owns at
least 85% of the voting stock of the Company outstanding at the time the
transaction commenced (excluding shares owned by certain employee stock
ownership plans and persons who are both directors and officers of the
Company) or (iii) at or subsequent to the time an interested stockholder
becomes such, the business combination is both approved by the Board of
Directors and authorized at an annual or special meeting of the Company's
stockholders, not by written consent, by the affirmative vote of at least 66
2/3% of the outstanding voting stock not owned by the interested stockholder.
 
                                      66
<PAGE>
 
Because EDS became an interested stockholder at a time when the restrictions
did not apply, the restrictions will not apply to any business combination
with EDS.
 
  Under certain circumstances, Section 203 of the DGCL makes it more difficult
for a person who would be an "interested stockholder" to effect various
business combinations with a corporation for a three-year period, although the
stockholders may elect to exclude a corporation from the restrictions imposed
thereunder. The Certificate of Incorporation of the Company does not exclude
the Company from the restrictions imposed under Section 203 of the DGCL. It is
anticipated that the provisions of Section 203 of the DGCL may encourage
companies interested in acquiring the Company to negotiate in advance with the
Board of Directors, since the stockholder approval requirement would be
avoided if a majority of the directors then in office approves, prior to the
date on which a stockholder becomes an interested stockholder, either the
business combination or the transaction which results in the stockholder
becoming an interested stockholder.
 
CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS
 
  The summary set forth below describes certain provisions of the Certificate
of Incorporation and Bylaws. The summary is qualified in its entirety by
reference to the provisions of the Certificate of Incorporation and Bylaws,
copies of which have been filed as exhibits to the Registration Statement of
which this Prospectus forms a part.
 
  Certain of the provisions of the Certificate of Incorporation and Bylaws
discussed below may have the effect, either alone or in combination with the
provisions of Section 203 discussed above, of making more difficult or
discouraging a tender offer, proxy contest or other takeover attempt that is
opposed by the Board of Directors but that a stockholder might consider to be
in such stockholder's best interest. Those provisions include (i) restrictions
on the rights of stockholders to remove directors, (ii) prohibitions against
stockholders calling a special meeting of stockholders or acting by unanimous
written consent in lieu of a meeting and (iii) requirements for advance notice
of actions proposed by stockholders for consideration at meetings of the
stockholders. In addition, the Certificate of Incorporation contains
provisions relating to the allocation of certain corporate opportunities and
resolution of certain potential conflicts of interest. See "--Corporate
Opportunity and Conflict of Interest Policies."
 
CLASSIFIED BOARD OF DIRECTORS; REMOVAL; NUMBER OF DIRECTORS; FILLING
VACANCIES
 
  The Certificate of Incorporation and Bylaws of the Company provide that the
Board of Directors--except for directors who may be elected by the holders of
Preferred Stock or any other series or class of stock--will be divided into
three classes of directors, with the classes to be as nearly equal in number
as possible. One class is to be originally elected for a term expiring at the
annual meeting of stockholders to be held in 1999, another class is to be
originally elected for a term expiring at the annual meeting of stockholders
to be held in 2000 and another class is to be originally elected for a term
expiring at the annual meeting of stockholders to be held in 2001. Each
director is to hold office until his or her successor is duly elected and
qualified. Commencing with the 1999 annual meeting of stockholders, directors
elected to succeed directors whose terms then expire will be elected for a
term of office to expire at the third succeeding annual meeting of
stockholders after their election, with each director to hold office until
such person's successor is duly elected and qualified.
 
  The Bylaws provide that, subject to any rights of holders of Preferred Stock
or any other series or class of stock to elect directors under specified
circumstances, the number of directors will be fixed from time to time
exclusively pursuant to a resolution adopted by directors constituting a
majority of the total number of directors that the Company would have if there
were no vacancies on the Board of Directors (the "Whole Board"), with the
Whole Board consisting of not more than twelve nor less than three directors.
The Bylaws also provide that, subject to any rights of holders of Preferred
Stock or any other series or class of stock, and unless the Board of Directors
otherwise determines, any vacancies will be filled only by the affirmative
vote of a majority of the remaining directors, even if less than a quorum.
Accordingly, absent an amendment to the Bylaws, the Board of Directors could
prevent any stockholder from enlarging the Board of Directors and filling the
new directorships with such stockholder's own nominees.
 
                                      67
<PAGE>
 
  The Certificate of Incorporation and Bylaws of the Company provide that,
subject to the rights of holders of Preferred Stock or any other series or
class of stock to elect directors under specified circumstances, effective as
of the Trigger Date, directors may be removed only for cause and only upon the
affirmative vote of holders of at least 80% of the voting power of all the
then outstanding shares of stock entitled to vote generally in the election of
directors ("Voting Stock"), voting together as a single class; provided
however, that prior to the Trigger Date, directors may be removed, without
cause, with the affirmative vote of the holders of at least a majority of the
voting power of the then outstanding Voting Stock, voting together as a class.
 
  The classification of directors will have the effect of making it more
difficult for stockholders to change the composition of the Board of
Directors. At least two annual meetings of stockholders, instead of one, will
generally be required to effect a change in a majority of the Board of
Directors. Such a delay may help ensure that the Company's directors, if
confronted by a holder attempting to force a proxy contest, a tender or
exchange offer, or an extraordinary corporate transaction, would have
sufficient time to review the proposal as well as any available alternatives
to the proposal and to act in what they believe to be the best interest of the
stockholders. The classification provisions will apply to every election of
directors, however, regardless of whether a change in the composition of the
Board of Directors would be beneficial to the Company and its stockholders and
whether or not a majority of the Company's stockholders believe that such a
change would be desirable.
 
  The classification provisions could also have the effect of discouraging a
third party from initiating a proxy contest, making a tender offer or
otherwise attempting to obtain control of the Company, even though such an
attempt might be beneficial to the Company and its stockholders. The
classification of the Board of Directors could thus increase the likelihood
that incumbent directors will retain their positions. In addition, because the
classification provisions may discourage accumulations of large blocks of the
Company's stock by purchasers whose objective is to take control of the
Company and remove a majority of the Board of Directors, the classification of
the Board of Directors could tend to reduce the likelihood of fluctuations in
the market price of the Common Stock that might result from accumulations of
large blocks. Accordingly, stockholders could be deprived of certain
opportunities to sell their shares of Common Stock at a higher market price
than might otherwise be the case.
 
 NO STOCKHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS
 
  The Certificate of Incorporation and Bylaws of the Company provide that,
effective as of the Trigger Date, and subject to the rights of any holders of
Preferred Stock or any other series or class of stock to elect additional
directors under specified circumstances, stockholder action can be taken only
at an annual or special meeting of stockholders and stockholder action may not
be taken by written consent in lieu of a meeting. The Bylaws provide that,
subject to the rights of holders of any series of Preferred Stock to elect
additional directors under specified circumstances, special meetings of
stockholders can be called only by the Board of Directors pursuant to a
resolution adopted by a majority of the Whole Board or the Chairman of the
Board; provided that, prior to the Trigger Date, special meetings can also be
called at the request of the holders of a majority of the voting power of the
then outstanding Voting Stock. Effective as of the Trigger Date, stockholders
are not permitted to call a special meeting or to require that the Board of
Directors call a special meeting of stockholders. Moreover, the business
permitted to be conducted at any special meeting of stockholders is limited to
the business brought before the meeting pursuant to the notice of meeting
given by the Company.
 
  The provisions of the Certificate of Incorporation and Bylaws of the Company
prohibiting stockholder action by written consent and permitting special
meetings to be called only by the Chairman or at the request of a majority of
the Whole Board may have the effect, as of the Trigger Date, of delaying
consideration of a stockholder proposal until the next annual meeting. The
provisions would also prevent the holders of a majority of the voting power of
the Voting Stock from unilaterally using the written consent procedure to take
stockholder action. Moreover, a stockholder could not force stockholder
consideration of a proposal over the opposition of the Chairman or a majority
of the Whole Board by calling a special meeting of stockholders prior to the
time such parties believe such consideration to be appropriate.

 ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS AND STOCKHOLDER
 PROPOSALS
 
  The Company's Bylaws establish an advance notice procedure for stockholders
to make nominations of candidates for election as directors or bring other
business before an annual meeting of stockholders of the Company (the
"Stockholder Notice Procedure").
 
  The Stockholder Notice Procedure provides that only persons who are
nominated by, or at the direction of, the Board of Directors, or by a
stockholder who has given timely written notice containing specified
information to the Secretary of the Company prior to the meeting at which
directors are to be elected, will be eligible for election as directors of the
Company. The Stockholder Notice Procedure also provides that at an annual
meeting only such business may be conducted as has been brought before the
meeting by, or at the direction of, the Chairman or the Board of Directors or
by a stockholder who has given timely written notice containing specified
information to the Secretary of the Company of such stockholder's intention to
bring such business before such meeting. Under the Stockholder Notice
Procedure, for notice of stockholder nominations or proposals to be made at an
annual meeting to be timely, such notice must be received by the Company not
less than 90 days nor more than 120 days prior to the first anniversary of the
previous year's annual meeting (or, in the event that the date of the annual
meeting is advanced by more than 20 days or delayed by more than 70 days from
such anniversary date, not earlier than the 120th day prior to such meeting
and not later than the later of (x) the 90th day prior to such meeting and (y)
the 10th day after public announcement of the date of such meeting is first
made). Notwithstanding the foregoing, in the event that the number of
directors to be elected is increased and there is no public announcement
naming all of the nominees for director or specifying the size of the
increased Board of Directors made by the Company at least 100 days prior to
the first anniversary of the preceding year's annual meeting, a stockholder's
notice will be timely, but only with respect to nominees for any new positions
created by such increase, if it is received by the Company not later than the
10th day after such public announcement is first made by the Company. Under
the Stockholder Notice Procedure, for notice of a stockholder nomination to be
made at a special meeting at which directors are to be elected to be timely,
such notice must be received by the Company not earlier than the 120th day
before such meeting and not later than the later of (x) the 90th day prior to
such meeting and (y) the 10th day after public announcement of the date of
such meeting is first made. If the Chairman of the Board or other officer
presiding at a meeting determines at or prior to the meeting that a person was
not nominated or other business was not brought before the meeting in
accordance with the Stockholder Notice Procedure, such person will not be
eligible for election as a director, or such business will not be conducted at
such meeting, as the case may be.
 
  By requiring advance notice of nominations by stockholders, the Stockholder
Notice Procedure will afford the Board of Directors an opportunity to consider
the qualifications of the proposed nominees and, to the extent deemed
necessary or desirable by the Board of Directors, to inform stockholders about
such qualifications. By requiring advance notice of other proposed business,
the Stockholder Notice Procedure will also provide a more orderly procedure
for conducting annual meetings of stockholders and, to the extent deemed
necessary or desirable by the Board of Directors, will provide the Board of
Directors with an opportunity to inform stockholders, prior to such meetings,
of any business proposed to be conducted at such meetings, together with any
recommendations as to the Board of Directors' position regarding action to be
taken with respect to such business, so that stockholders can better decide
whether to attend such a meeting or to grant a proxy regarding the disposition
of any such business.
 
  Although the Bylaws do not give the Board of Directors any power to approve
or disapprove stockholder nominations for the election of directors or
proposals for action, they may have the effect of precluding a contest for the
election of directors or the consideration of stockholder proposals if the
proper procedures are not followed, and of discouraging or deterring a third
party from conducting a solicitation of proxies to elect its own slate of
directors or to approve its own proposal, without regard to whether
consideration of such nominees or proposals might be harmful or beneficial to
the Company and its stockholders.
 
  The Stockholder Notice Procedure does not apply to EDS and its affiliates
prior to the Trigger Date.
 
                                      69

 AMENDMENTS
 
  The Certificate of Incorporation and Bylaws require that, effective as of
the Trigger Date, any amendment to the provisions of the Bylaws or to certain
provisions of the Certificate of Incorporation, including those provisions
discussed above, must be approved by the holders of at least 80% of the Voting
Stock. This requirement, as of the Trigger Date, will prevent a stockholder
with only a majority of the Common Stock from avoiding the requirements of the
provisions discussed above by amending or repealing such provisions. The
Certificate of Incorporation further provides that the Bylaws may be amended
by the Company's Board of Directors.
 
 LIABILITY OF DIRECTORS; INDEMNIFICATION
 
  The Certificate of Incorporation provides that a director will not be
personally liable for monetary damages to the Company or its stockholders for
breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) for paying a dividend or
approving a stock repurchase in violation of Section 174 of the DGCL or (iv)
for any transaction from which the director derived an improper personal
benefit. Any amendment or repeal of such provision shall not adversely affect
any right or protection of a director existing under such provision for any
act or omission occurring prior to such amendment or repeal.
 
  The Bylaws provide that the Company will indemnify any person who was or is
a party to any threatened, pending or completed action, suit or proceeding
because he or she is or was a director or officer of the Company, or is or was
serving at the request of the Company as a director or officer of another
corporation, partnership or other enterprise. The Bylaws provide that this
indemnification will be from and against expenses, judgments, fines and
amounts paid in settlement by the indemnitee. However, this indemnification
will only be provided if the indemnitee acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the Company.
 
 CORPORATE OPPORTUNITY AND CONFLICT OF INTEREST POLICIES
 
  In order to address certain potential conflicts of interest between the
Company and EDS, the Certificate of Incorporation contains provisions
concerning the conduct of certain affairs of the Company as they may involve
EDS and its subsidiaries (other than the Company and its subsidiaries) and
their respective officers and directors, and the powers, rights, duties and
liabilities of the Company and its subsidiaries and their respective officers,
directors and stockholders in connection therewith. In general, these
provisions recognize that the Company and EDS and their respective
subsidiaries may engage in the same or similar business activities and lines
of business and have an interest in the same areas of corporate opportunities
and that the Company and EDS and their subsidiaries will continue to have
contractual and business relations with each other (including service of
officers and directors of EDS as directors of the Company). See "Management--
Directors and Executive Officers."
 
  For purposes of these provisions, the terms "Company" and "EDS" include
their subsidiaries and other entities in which they respectively beneficially
own, directly or indirectly, 50 percent or more of the outstanding voting
securities or interests (except that "EDS" does not include the Company and
its subsidiaries and such other entities), and, in the case of EDS, all
successors to EDS by way of merger, consolidation or sale of all or
substantially all its assets.
 
  The Certificate of Incorporation provides that any person purchasing or
otherwise acquiring any interest in any shares of capital stock of the Company
shall be deemed to have notice of and to have consented to these provisions.
 
  Corporate Opportunity Policy. The Certificate of Incorporation provides
that, except as EDS may otherwise agree in writing, EDS will have the right
(i) to engage in the same or similar business activities or lines of business
as the Company, (ii) to do business with any potential or actual client,
customer or supplier of
 
                                      70
<PAGE>
 
the Company and (iii) to employ or engage any officer or employee of the
Company. Neither EDS nor any officer or director thereof will be liable to the
Company or its stockholders for breach of any fiduciary duty by reason of
these activities.
 
  If EDS acquires knowledge of a potential transaction or matter that may be a
corporate opportunity for both EDS and the Company, EDS will have no duty to
communicate that opportunity to the Company. Furthermore, EDS will not be
liable to the Company or its stockholders because EDS pursues or acquires that
corporate opportunity for itself, directs that corporate opportunity to
another person or entity or does not present that corporate opportunity to the
Company.
 
  If a director or officer of the Company who is also a director or officer of
EDS acquires knowledge of a potential transaction or matter that may be a
corporate opportunity for both the Company and EDS, the Certificate of
Incorporation requires that the director or officer of the Company act in good
faith in accordance with the following three-part policy, and a director or
officer so acting is deemed to have acted reasonably and in good faith and
fully to have satisfied his or her duties of loyalty and fiduciary duties to
the Company and its stockholders with respect to such opportunity.
 
  First, a corporate opportunity offered to any person who is a director but
not an officer of the Company and who is also an officer (whether or not a
director) of EDS will belong to EDS, unless the opportunity is expressly
offered to that person primarily in his or her capacity as a director of the
Company, in which case the opportunity will belong to the Company.
 
  Second, a corporate opportunity offered to any person who is an officer
(whether or not a director) of the Company and who is also a director but not
an officer of EDS will belong to the Company, unless the opportunity is
expressly offered to that person primarily in his or her capacity as a
director of EDS, in which case the opportunity will belong to EDS.
 
  Third, a corporate opportunity offered to any other person who is either an
officer of both the Company and EDS or a director of both the Company and EDS
will belong to EDS or to the Company, as the case may be, if the opportunity
is expressly offered to the person primarily in his or her capacity as an
officer or director of EDS or of the Company, respectively. Otherwise, the
opportunity will belong to EDS.
 
  Under the Certificate of Incorporation, any corporate opportunity that
belongs to EDS or to the Company pursuant to the foregoing policy will not be
pursued by the other (or directed by the other to another person or entity)
unless and until EDS or the Company, as the case may be, determines not to
pursue the opportunity. If the party to whom the corporate opportunity belongs
does not, however, within a reasonable period of time, begin to pursue, or
thereafter continue to pursue, such opportunity diligently and in good faith,
the other party may pursue such opportunity (or direct it to another person or
entity).
 
  A director or officer of the Company who acts in accordance with the
foregoing three-part policy: (i) will be deemed fully to have satisfied his or
her fiduciary duties to the Company and its stockholders with respect to such
corporate opportunity; (ii) will not be liable to the Company or its
stockholders for any breach of fiduciary duty by reason of the fact that EDS
pursues or acquires such opportunity for itself or directs such corporate
opportunity to another person or does not communicate information regarding
such opportunity to the Company; (iii) will be deemed to have acted in good
faith and in a manner he or she reasonably believes to be in the best
interests of the Company; and (iv) will be deemed not to have breached his or
her duty of loyalty to the Company or its stockholders and not to have derived
an improper benefit therefrom.
 
  Under the Certificate of Incorporation, "corporate opportunities"
potentially allocable to the Company consist of business opportunities which
(i) the Company is financially able to undertake; (ii) are, from their nature,
in the Company's line or lines of business and are of practical advantage to
the Company; and (iii) are ones in which the Company has an interest or
reasonable expectancy.
 
                                      71
<PAGE>
 
  In addition, "corporate opportunities" do not include transactions in which
the Company or EDS is permitted to participate pursuant to any agreement
between the Corporation and EDS that is in effect as of the time any equity
security of the Company is held of record by any person other than EDS or
subsequently entered into with the approval of the Disinterested Directors.
 
  For purposes of these corporate opportunity provisions, a director of the
Company who is chairman of the Board of Directors (or a committee thereof) or
chief executive officer will not be deemed to be an officer of the Company by
reason of holding such position, unless such person is a full-time employee of
the Company.
 
  Conflict of Interests Policy. The Certificate of Incorporation provides that
no contract, agreement, arrangement or transaction between the Company and EDS
or any customer or supplier or any entity in which a director of the Company
has a financial interest (a "Related Entity"), or between the Company and one
or more of the directors or officers of the Company, EDS or any Related
Entity, or any amendment, modification or termination thereof, will be
voidable solely because EDS or such customer or supplier, any Related Entity,
or any one or more of the officers or directors of the Company, EDS or any
Related Entity are parties thereto, or solely because any such directors or
officers are present at or participate in the meeting of the Board of
Directors or committee thereof which authorizes the contract, agreement,
arrangement, transaction, amendment, modification or termination (each, a
"Transaction") or solely because their votes are counted for such purpose, if
a specified standard is satisfied. That standard will be satisfied, and EDS,
the Related Entity and the directors and officers of the Company, EDS or the
Related Entity (as applicable) will be deemed to have acted reasonably and in
good faith (to the extent such standard is applicable to such person's
conduct) and fully to have satisfied any duties of loyalty and fiduciary
duties they may have to the Company and its stockholders with respect to such
transaction if any of the following four requirements are met:
 
    (i) the material facts as to the Transaction are disclosed or known to
  the Board of Directors or the committee thereof that authorizes the
  Transaction, and the Board of Directors or such committee in good faith
  approves the Transaction by a majority of the Disinterested Directors on
  the Board of Directors or such committee, even if the Disinterested
  Directors are less than a quorum;
 
    (ii) the material facts as to the Transaction are disclosed or known to
  the holders of Voting Stock entitled to vote thereon, and the Transaction
  is specifically approved by vote of the holders of a majority of the then
  outstanding Voting Stock not owned by EDS or such Related Entity, voting
  together as a single class;
 
    (iii) the Transaction is effected pursuant to guidelines which are in
  good faith approved by a majority of the Disinterested Directors on the
  Board of Directors or the applicable committee thereof or by vote of the
  holders of a majority of the then outstanding Voting Stock not owned by EDS
  or such Related Entity, voting together as a single class; or
 
    (iv) the Transaction is fair to the Company as of the time it is approved
  by the Board of Directors, a committee thereof or the stockholders of the
  Company.
 
  The Certificate of Incorporation also provides that any such Transaction
authorized, approved or effected, and each of such guidelines so authorized or
approved, as described in (i), (ii) or (iii) above, shall be deemed to be
entirely fair to the Company and its stockholders; provided that, if such
authorization or approval is not obtained, or such Transaction is not so
effected, no presumption shall arise that such Transaction or guideline is not
fair to the Company and its stockholders. In addition, the Certificate of
Incorporation provides that EDS shall not be liable to the Company or its
stockholders for breach of any fiduciary duty that EDS may have by reason of
the fact that EDS takes any action in connection with any transaction between
EDS and the Company.
 
  Effective as of the Trigger Date, the affirmative vote of the holders of
more than 80 percent of the outstanding Voting Stock, voting together as a
single class, will be required to alter, amend or repeal any of these conflict
of interest or corporate opportunity provisions in a manner adverse to the
interests of EDS.

RIGHTS TO PURCHASE SECURITIES AND OTHER PROPERTY
 
  The Certificate of Incorporation authorizes the Board of Directors to create
and issue rights entitling the holders thereof to purchase from the Company
shares of capital stock or other securities or property. The times at which
and terms upon which such rights are to be issued would be determined by the
Board of Directors and set forth in the contracts or instruments that evidence
such rights. The authority of the Board of Directors with respect to such
rights includes, but is not limited to, determination of (i) the purchase
price of the capital stock to be purchased upon exercise of such rights; (ii)
provisions relating to the times at which and the circumstances under which
such rights may be exercised or sold or otherwise transferred, either together
with or separately from, any other stock or other securities of the Company;
(iii) provisions which adjust the number or exercise price of such rights or
amount or nature of the stock receivable upon exercise of such rights in the
event of a combination, split or recapitalization of any stock of the Company,
a change in ownership of the Company's stock or other securities or a
reorganization, merger, consolidation, sale of assets or other occurrence
relating to the Company or any stock of the Company, and provisions
restricting the ability of the Company to enter into any such transaction
absent an assumption by the other party or parties thereto of the obligations
of the Company under such rights; (iv) provisions which deny the holder of a
specified percentage of the outstanding securities of the Company the right to
exercise such rights and cause such rights held by such holder to become void;
(v) provisions which permit the Company to redeem or exchange such rights; and
(vi) the appointment of the rights agent with respect to such rights. This
provision is intended to confirm the authority of the Board of Directors to
issue such share purchase rights or other rights to purchase stock or
securities of the Company or any other corporation.
 
LISTING
 
  Application will be made to list the Class A Common Stock on the Nasdaq
National Market under the symbol "UGSI."
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is The Bank of New
York.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to the Offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could adversely affect prevailing market prices.
 
  Upon completion of the Offering, the Company will have    shares of Class A
Common Stock issued and outstanding (    if the U.S. Underwriters' over-
allotment option is exercised in full) and     shares of Class B Common Stock
issued and outstanding. All of the shares of Class A Common Stock to be sold
in the Offering will be freely tradable without restrictions or further
registration under the Securities Act, except that shares purchased by an
"affiliate" of the Company (as that term is defined in Rule 144) will be
subject to the resale limitations of Rule 144. All of the outstanding shares
of Class B Common Stock are owned by EDS and have not been registered under
the Securities Act and may not be sold in the absence of an effective
registration statement under the Securities Act other than in accordance with
Rule 144 or another exemption from registration ("Restricted Shares").
Restricted Shares will become eligible for resale in the public market at
various dates in the future.
 
  The Restricted Shares will constitute "restricted securities" within the
meaning of Rule 144 promulgated under the Securities Act and will be eligible
for sale in the open market after the Offering subject to the contractual
lockup provisions and applicable requirements of Rule 144 described below. In
addition, for as long as EDS is able to cause a majority of the Company's
Board of Directors to be elected, it will be able to cause the Company at any
time to register under the Securities Act all or a portion of the Common Stock
owned by it, in which event such shares could be sold publicly upon the
effectiveness of any such registration without
 
                                      73
<PAGE>
 
restriction. EDS may also, at any time following the contractual lockup
provisions described below, sell any or all of the Class B Common Stock in a
private placement without regard to the Rule 144 restrictions described below.
 
  In general, under Rule 144 as currently in effect, if a period of at least
one year has elapsed between the later of the date on which "restricted
shares" (as that phrase is defined in Rule 144) were acquired from the Company
and the date on which they were acquired from an "affiliate" of the Company
(an "Affiliate," as that term is defined in Rule 144), then the holder of such
restricted shares (including an Affiliate) is entitled to sell a number of
shares within any three-month period that does not exceed the greater of (i)
one percent of the then outstanding shares of the Common Stock or (ii) the
average weekly reported volume of trading of the Common Stock during the four
calendar weeks preceding such sale. Sales under Rule 144 are also subject to
certain requirements pertaining to the manner of such sales, notices of such
sales and the availability of current public information concerning the
Company. Affiliates may sell shares not constituting restricted shares in
accordance with the foregoing volume limitations and other requirements but
without regard to the one-year period. Under Rule 144(k), if a period of at
least two years has elapsed between the later of the date on which restricted
shares were acquired from the Company and the date on which they were acquired
from an Affiliate, a holder of such restricted shares who is not an Affiliate
at the time of the sale and has not been an Affiliate for at least three
months prior to the sale would be entitled to sell the shares immediately
without regard to the volume limitations and other conditions described above.
The foregoing description of Rule 144 is not intended to be a complete
description thereof.
 
  Sales of significant amounts of the Class A Common Stock, or the perception
that such sales could occur, could have an adverse impact on the market price
of the Class A Common Stock. Each of the Company and its directors, executive
officers and EDS has agreed that, without the prior written consent of Morgan
Stanley & Co. Incorporated on behalf of the Underwriters, it will not, during
the period ending 180 days after the date of this Prospectus, (i) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer, lend or dispose of, directly or indirectly,
any shares of Class A Common Stock or any securities convertible into or
exercisable or exchangeable for Class A Common Stock or (ii) enter into any
swap or other arrangement that transfers to another, in whole or in part, any
of the economic consequences of ownership of the Class A Common Stock, whether
any such transaction described in clause (i) or (ii) above is to be settled by
delivery of Class A Common Stock or such other securities, in cash or
otherwise. The restrictions described in this paragraph do not apply to (x)
the sale of Shares to the Underwriters, (y) the issuance by the Company of
shares of Class A Common Stock upon the exercise of an option or a warrant or
the conversion of a security outstanding on the date of this Prospectus of
which the Underwriters have been advised in writing or (z) transactions by any
person other than the Company relating to shares of Class A Common Stock or
other securities acquired in open market transactions after the completion of
the offering of the Shares. See "Underwriters."
 
  The Company and EDS are also parties to the Registration Rights Agreement
pursuant to which EDS may demand registration under the Securities Act of
shares of the Company's capital stock held by it at any time subject to its
agreement not to sell any shares prior to the expiration of 180 days from the
date of this Prospectus. So long as EDS owns capital stock of the Company
representing more than 20% of the total voting power of all classes of stock
of the Company outstanding, EDS may exercise this "demand registration" at any
time and on an unlimited number of occasions. Transferees of EDS (and EDS upon
a reduction in its ownership to less than 20% of the voting power) may only
exercise this demand registration right three times. If EDS owns less than 50%
of the total voting power of all classes of stock of the Company outstanding,
the Company may postpone a demand registration under certain customary
circumstances. In addition, at any time prior to the tenth anniversary of the
date of the Registration Rights Agreement, EDS may request the Company to
include shares of the Company's capital stock held by it in any registration
proposed by the Company of such capital stock under the Securities Act. The
Registration Rights Agreement contains provisions regarding the pro rata
payment of expenses by the Company and EDS and regarding mutual
indemnification agreements between the Company and EDS for certain securities
laws violations.

     CERTAIN FEDERAL INCOME TAX CONSEQUENCES FOR NON-UNITED STATES HOLDERS
 
  The following is a general summary of certain United States federal income
and estate tax consequences expected to result under current law from the
purchase, ownership and taxable disposition of Class A Common Stock by a
person or entity other than (i) a citizen or resident of the United States,
(ii) a corporation, partnership or other entity created or organized in or
under the laws of the United States or of any state thereof, (iii) an estate,
the income of which is subject to United States federal income taxation
regardless of its source or (iv) a trust whose administration is subject to
the primary supervision of a United States court and which has one or more
United States persons who have the authority to control all substantial
decisions of the trust (a "Non-U.S. Holder"). This summary does not address
all of the United States federal income and estate tax considerations that may
be relevant to a Non-U.S. Holder in light of its particular circumstances or
to Non-U.S. Holders that may be subject to special treatment under United
States federal income tax laws (such as insurance companies, tax-exempt
organizations, financial institutions, brokers, and dealers in securities).
Furthermore, this summary does not discuss any aspects of state, local or
foreign taxation. This summary is based on current provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), Treasury regulations, judicial
opinions, published positions of the United States Internal Revenue Service
(the "IRS") and other applicable authorities, all of which are subject to
change, possibly with retroactive effect. Each prospective purchaser of Class
A Common Stock is advised to consult its tax advisor with respect to the tax
consequences of acquiring, holding and disposing of Class A Common Stock.
 
DIVIDENDS
 
  Dividends paid to a Non-U.S. Holder of Class A Common Stock generally will
be subject to withholding of United States federal income tax at a 30 percent
rate (or such lower rate as may be specified by an applicable income tax
treaty) unless the dividends are effectively connected with the conduct of a
trade or business of the Non-U.S. Holder within the United States (and, if an
income tax treaty applies, is applicable to a United States permanent
establishment of the Non-United States Holder) and the Non-United States
Holder provides the payor with proper documentation (generally I.R.S. Form
4224 or any successor form), in which case the dividends will be taxed at
ordinary United States federal income tax rates and will not be subject to the
withholding tax described above. If the Non-U.S. Holder is a corporation, such
effectively connected income may also be subject to an additional "branch
profits tax" which is imposed, under certain circumstances, at a rate of 30%
(or such lower rate as may be specified by an applicable treaty) of the Non-
United States corporation's "effectively connected earnings and profits,"
subject to certain adjustments.
 
SALE OR DISPOSITION OF CLASS A COMMON STOCK
 
  A Non-U.S. Holder generally will not be subject to United States federal
income tax in respect of any gain recognized on the sale or other disposition
of Class A Common Stock unless (i) the gain is effectively connected with a
trade or business of the Non-U.S. Holder in the United States; (ii) in the
case of a Non-U.S. Holder who is an individual and holds the Class A Common
Stock as a capital asset, (a) such holder is present in the United States for
183 or more days in the taxable year of the disposition and (b) such holder
has a "tax home" in the United States for United States federal income tax
purposes or maintains an office or other fixed place of business in the United
States to which such gain is attributable; (iii) the Non-U.S. Holder is
subject to tax pursuant to the provisions of United States federal income tax
law applicable to certain United States expatriates whose loss of U.S.
citizenship has as one of its principal purposes the avoidance of U.S. taxes;
or (iv) the Company becomes a U.S. real property holding corporation and
either (a) the Class A Common Stock ceases to be "regularly traded on an
established securities market" for United States federal income tax purposes
or (b) the Non-U.S. Holder has held, directly or indirectly, at any time
during the five-year period ending on the date of disposition (or, if shorter,
the Non-U.S. Holder's holding period), more than 5 percent of all of the
Company's outstanding Common Stock. The Company is not, and does not
anticipate becoming, a U.S. real property holding company.
 
                                      75
<PAGE>
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  The Company must report annually to the IRS and to each Non-U.S. Holder the
amount of dividends paid to such holder and the amount, if any, of tax
withheld with respect to such dividends. This information may also be made
available to the tax authorities in the Non-U.S. Holder's country of
residence.
 
  United States backup withholding (which generally is a withholding tax
imposed at the rate of 31% on certain payments to persons that fail to furnish
certain information under the United States information reporting
requirements) generally will not apply to dividends paid to Non-United States
Holders if such dividends are subject to the 30% withholding discussed above
(or that are not so subject because a tax treaty applies that reduces or
eliminates such 30% withholding). In the case of dividends which are not
described in the preceding sentence, backup withholding would still not apply
(i) under current law, if such dividends are paid before January 1, 1999 to a
Non-United States Holder at an address outside of the United States or (ii)
under recently promulgated final United States Treasury regulations which are
to become effective as of January 1, 1999, if certain certification procedures
(or, in the case of payments made outside the United States with respect to an
offshore account, certain documentary evidence procedures) are satisfied.
 
  Upon the sale or other taxable disposition of Class A Common Stock by a Non-
U.S. Holder to or through a United States office of a broker, the broker must
backup withhold at a rate of 31 percent and report the sale to the IRS, unless
the holder certifies its non-U.S. status under penalties of perjury or
otherwise establishes exemption. Upon the sale or other taxable disposition of
Class A Common Stock by a Non-U.S. Holder to or through the foreign office of
a United States broker, or a foreign broker with certain types of
relationships to the United States, the broker must report the sale to the IRS
(but, prior to January 1, 1999, is probably not required to backup withhold)
unless the broker has documentary evidence in its files that the seller is a
Non-U.S. Holder and certain other conditions are met, or the holder otherwise
establishes an exemption. A sale or other taxable disposition of Class A
Common Stock by a Non-U.S. Holder to or through the foreign office of a
foreign broker that does not have certain types of relationships to the United
States is generally not subject to either information reporting or backup
withholding.
 
  Backup withholding is not an additional U.S. federal income tax. Amounts
withheld under the backup withholding rules are generally allowable as a
refund or credit against such Non-U.S. Holder's United States federal income
tax liability, if any, provided that the required information is furnished to
the IRS.
 
 FEDERAL ESTATE TAXES
 
  Class A Common Stock owned or treated as owned by an individual who is not a
citizen or resident (as specially defined for United States federal estate tax
purposes) of the United States at the time of death will be included in such
individual's gross estate for United States federal estate tax purposes,
unless an applicable estate tax treaty provides otherwise.

</TABLE>
 
  The U.S. Underwriters and the International Underwriters, and the U.S.
Representatives and the International Representatives, are collectively
referred to as the "Underwriters" and the "Representatives," respectively. The
Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Class A Common
Stock offered hereby are subject to the approval of certain
 
                                      77
<PAGE>
 
legal matters by their counsel and to certain other conditions. The
Underwriters are obligated to take and pay for all of the shares of Class A
Common Stock offered hereby (other than those covered by the U.S.
Underwriters' over-allotment option described below) if any such shares are
taken.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented and agreed that, with certain exceptions: (i)
it is not purchasing any Shares (as hereinafter defined) for the account of
anyone other than a United States or Canadian Person (as hereinafter defined)
and (ii) it has not offered or sold, and will not offer or sell, directly or
indirectly, any Shares or distribute any prospectus relating to the Shares
outside the United States or Canada or to anyone other than a United States or
Canadian Person. Pursuant to the Agreement between U.S. and International
Underwriters, each International Underwriter has represented and agreed that,
with certain exceptions: (i) it is not purchasing any Shares for the account
of any United States or Canadian Person and (ii) it has not offered or sold,
and will not offer or sell, directly or indirectly, any Shares or distribute
any prospectus relating to the Shares in the United States or Canada or to any
United States or Canadian Person. With respect to any Underwriter that is a
U.S. Underwriter and an International Underwriter, the foregoing
representations and agreements (i) made by it in its capacity as a U.S.
Underwriter apply only to it in its capacity as a U.S. Underwriter and (ii)
made by it in its capacity as an International Underwriter apply only to it in
its capacity as an International Underwriter. The foregoing limitations do not
apply to stabilization transactions or to certain other transactions specified
in the Agreement between U.S. and International Underwriters. As used herein,
"United States or Canadian Person" means any national or resident of the
United States or Canada, or any corporation, pension, profit-sharing or other
trust or other entity organized under the laws of the United States or Canada
or of any political subdivision thereof (other than a branch located outside
the United States and Canada of any United States or Canadian Person), and
includes any United States or Canadian branch of a person who is otherwise not
a United States or Canadian Person. All shares of Class A Common Stock to be
purchased by the Underwriters under the Underwriting Agreement are referred to
herein as the "Shares."
 
  Pursuant to the Agreement between U.S. and International Underwriters, sales
may be made between the U.S. Underwriters and International Underwriters of
any number of Shares as may be mutually agreed. The per share price of any
Shares so sold shall be the public offering price set forth on the cover page
hereof, in United States dollars, less an amount not greater than the per
share amount of the concession to dealers set forth below.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented that it has not offered or sold, and has
agreed not to offer or sell, any Shares, directly or indirectly, in any
province or territory of Canada or to, or for the benefit of, any resident of
any province or territory of Canada in contravention of the securities laws
thereof and has represented that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which such offer or sale is made.
Each U.S. Underwriter has further agreed to send to any dealer who purchases
from it any of the Shares a notice stating in substance that, by purchasing
such Shares, such dealer represents and agrees that it has not offered or
sold, and will not offer or sell, directly or indirectly, any of such Shares
in any province or territory of Canada or to, or for the benefit of, any
resident of any province or territory of Canada in contravention of the
securities laws thereof and that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which such offer or sale is made,
and that such dealer will deliver to any other dealer to whom it sells any of
such Shares a notice containing substantially the same statement as is
contained in this sentence.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has represented and agreed that (i) it has not
offered or sold and, prior to the date six months after the closing date for
the sale of the Shares to the International Underwriters, will not offer or
sell, any Shares to persons in the United Kingdom except to persons whose
ordinary activities involve them in acquiring, holding, managing or disposing
of investments (as principal or agent) for the purposes of their businesses or
otherwise in circumstances which have not resulted and will not result in an
offer to the public in the United Kingdom within the meaning

of the Public Offers of Securities Regulations 1995; (ii) it has complied and
will comply with all applicable provisions of the Financial Services Act 1986
with respect to anything done by it in relation to the Shares in, from or
otherwise involving the United Kingdom; and (iii) it has only issued or passed
on and will only issue or pass on in the United Kingdom any document received
by it in connection with the offering of the Shares to a person who is of a
kind described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 or is a person to whom such document
may otherwise lawfully be issued or passed on.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has further represented that it has not offered or
sold, and has agreed not to offer or sell, directly or indirectly, in Japan or
to or for the account of any resident thereof, any of the Shares acquired in
connection with the distribution contemplated hereby, except for offers or
sales to Japanese International Underwriters or dealers and except pursuant to
any exemption from the registration requirements of the Securities and
Exchange Law and otherwise in compliance with applicable provisions of
Japanese law. Each International Underwriter has further agreed to send to any
dealer who purchases from it any of the Shares a notice stating in substance
that, by purchasing such Shares, such dealer represents and agrees that it has
not offered or sold, and will not offer or sell, any of such Shares, directly
or indirectly, in Japan or to or for the account of any resident thereof
except for offers or sales to Japanese International Underwriters or dealers
and except pursuant to any exemption from the registration requirements of the
Securities and Exchange Law and otherwise in compliance with applicable
provisions of Japanese law, and that such dealer will send to any other dealer
to whom it sells any of such Shares a notice containing substantially the same
statement as is contained in this sentence.
 
  The Underwriters initially propose to offer part of the shares of Class A
Common Stock directly to the public at the public offering price set forth on
the cover page hereof and part to certain dealers at a price that represents a
concession not in excess of $   a share under the public offering price. Any
Underwriter may allow, and such dealers may reallow, a concession not in
excess of $   a share to other Underwriters or to certain dealers. After the
initial offering of the shares of Class A Common Stock, the offering price and
other selling terms may from time to time be varied by the Representatives.
 
  The Company has granted to the U.S. Underwriters an option, exercisable for
30 days from the date of this Prospectus, to purchase up to an aggregate of
additional shares of Class A Common Stock at the public offering price set
forth on the cover page hereof, less underwriting discounts and commissions.
The U.S. Underwriters may exercise such option solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
shares of Class A Common Stock offered hereby. To the extent such option is
exercised, each U.S. Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares of Class A Common Stock as the number set forth next to such U.S.
Underwriter's name in the preceding table bears to the total number of shares
of Class A Common Stock set forth next to the names of all U.S. Underwriters
in the preceding table.
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Class A Common Stock offered by them.
 
  Application will be made to list the Class A Common Stock for quotation on
the Nasdaq National Market under the symbol "UGSI."
 
  Each of the Company and its directors and executive officers and EDS has
agreed that, without the prior written consent of Morgan Stanley & Co.
Incorporated on behalf of the Underwriters, it will not, during the period
ending 180 days after the date of this Prospectus, (i) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase or
otherwise transfer, lend or dispose of, directly or indirectly, any shares of
Class A Common Stock or any securities convertible into or exercisable or
exchangeable for Class A Common Stock or (ii) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Class A Common Stock, whether any
such transaction described in clause (i) or (ii) above is to
 
                                      79
<PAGE>
 
be settled by delivery of Class A Common Stock or such other securities, in
cash or otherwise. The restrictions described in this paragraph do not apply
to (x) the sale of Shares to the Underwriters, (y) the issuance by the Company
of shares of Class A Common Stock upon the exercise of an option or a warrant
or the conversion of a security outstanding on the date of this Prospectus of
which the Underwriters have been advised in writing or (z) transactions by any
person other than the Company relating to shares of Class A Common Stock or
other securities acquired in open market transactions after the completion of
the offering of the Shares.
 
  In order to facilitate the offering of the Class A Common Stock, the
Underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the Class A Common Stock. Specifically, the Underwriters
may over-allot in connection with the offering, creating a short position in
the Class A Common Stock for their own account. In addition, to cover over-
allotments or to stabilize the price of the Class A Common Stock, the
Underwriters may bid for, and purchase, shares of Class A Common Stock in the
open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an Underwriter or a dealer for distributing the Class A
Common Stock in the offering, if the syndicate repurchases previously
distributed Class A Common Stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the Class A Common Stock above
independent market levels. The Underwriters are not required to engage in
these activities, and may end any of these activities at any time.
 
  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
 
 PRICING OF THE OFFERING
 
  Prior to this offering, there has been no public market for the Class A
Common Stock. The initial public offering price will be determined by
negotiations between the Company and the U.S. Representatives. Among the
factors to be considered in determining the initial public offering price will
be the future prospects of the Company and its industry in general, sales,
earnings and certain other financial operating information of the Company in
recent periods, and the price-earnings ratios, price-sales ratios, market
prices of securities and certain financial and operating information of
companies engaged in activities similar to those of the Company. The estimated
initial public offering price range set forth on the cover page of this
Preliminary Prospectus is subject to change as a result of market conditions
and other factors.
 
                                 LEGAL MATTERS

by this Prospectus will be passed upon for the Company by Baker & Botts,

Underwriters by Shearman & Sterling, New York, New York.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Electronic Data Systems Corporation:
 
  We have audited the accompanying balance sheets of Unigraphics Solutions
Inc., a subsidiary of Electronic Data Systems Corporation, as of December 31,
1996 and 1997, and the related statements of income and stockholder's net
investment, and cash flows for each of the years in the three-year period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Unigraphics Solutions Inc.
as of December 31, 1996 and 1997, and the results of its operations and its
cash flows for each of the years in the three-year period ended December 31,
1997 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Description of Business
 
  Unigraphics Solutions Inc., a wholly owned subsidiary of Electronic Data
Systems Corporation ("EDS"), was incorporated under the laws of the state of
Delaware on October 2, 1997. Unigraphics Solutions Inc. is the successor to
the Unigraphics business of EDS (the "Division") which operated within several
business units of EDS through December 31, 1997. Unigraphics Solutions Inc.
develops, markets and supports mechanical computer-aided design ("CAD"),
computer-aided manufacturing ("CAM") and computer-aided engineering ("CAE")
software to customers in more than 20 countries. All references to the
"Company" in the notes to the financial statements refer to Unigraphics
Solutions Inc. and its predecessor businesses and divisions.
 
  On January 1, 1998, EDS reorganized the business of the Division (the
"Reorganization"). As part of the Reorganization, the businesses of the
Division were combined under the Company. See Note 10 regarding transactions
related to the implementation of the Reorganization.
 
 Basis of presentation
 
  The accompanying financial statements have been prepared using EDS'
historical basis in the assets and liabilities of the Company. The financial
statements reflect the results of operations, financial condition and cash
flows of the Company as a component of EDS prior to the Reorganization and may
not be indicative of the actual results of operations and financial position
of the Company subsequent to the Reorganization. Management believes the
income statements include a reasonable allocation of administrative costs,
which are described in Note 2, incurred by EDS on behalf of the Company.
 
  All significant accounts and transactions among the Company's businesses
have been eliminated. For financial reporting purposes, the equity accounts of
the Company have been accumulated into a single disclosure caption entitled
Stockholder's Net Investment.
 
 Marketable Securities
 
  Marketable securities at December 31, 1997 consist of corporate equity
securities which are classified as available-for-sale. Management determines
the appropriate classification of all securities at the time of purchase and
reevaluates such designation as of each balance sheet date. The Company's
available-for-sale securities are recorded at fair value. Unrealized holding
gains, net of the related tax effect, of $1.7 million are excluded from net
income and included in Stockholder's Net Investment. A decline in the fair
value of any available-for-sale security below cost that is deemed other than
temporary is charged to earnings, resulting in the establishment of a new cost
basis for the security. Proceeds and realized gains from sales of marketable
securities totaled $5.1 million during the year ended December 31, 1997.
Specific identification is used to determine cost in computing gain or loss.
 
 Inventory Valuation
 
  Inventories, primarily consisting of computer equipment, are stated
principally at the lower of cost or market using the average cost method and
are included in prepaids and other current assets in the accompanying balance
sheet. The Company uses EDS' centralized inventory purchase system whereby
computer equipment is shipped directly from EDS or the vendor to the customer
and charged to the Company through an intercompany transaction. Included in
inventory are amounts for computer equipment which has been shipped to
customers and charged to the Company but not yet billed to customers.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Property and Equipment
 
  Property and equipment are stated at cost, less accumulated depreciation.
Depreciation of property and equipment is calculated using the straight-line
method over the estimated useful lives of the assets. Depreciation expense
totaled $6.7 million, $8.1 million and $7.3 million during the years ended
December 31, 1995, 1996 and 1997, respectively. The ranges of estimated useful
lives are as follows:

 Software, and Other Intangibles
 
  The Company capitalizes software development costs in compliance with
Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed."
Capitalization of software development costs begins upon the establishment of
technological feasibility of the product. The establishment of technological
feasibility and the ongoing assessment of the recoverability of these costs
requires considerable judgment by management with respect to certain external
forces including, but not limited to, anticipated future gross product
revenue, estimated economic life and changes in software and hardware
technology. Amortization of capitalized software development costs begins when
the products are available for release to customers and is generally computed
on a straight-line basis over 3 years or, if less, the remaining estimated
economic life of the product. Software purchased by the Company, including
amounts allocated to software when the Company was acquired by EDS, and
utilized in designing software and operations is capitalized and amortized on
a straight-line basis over a five- to eight-year period.
 
  In the accompanying statements of income, amortization is included in cost
of software for capitalized software development costs and in cost of software
or selling, general and administrative expenses for purchased software, as
determined by the nature of the software. Amortization of capitalized and
purchased software totaled $14.6 million, $14.8 million and $14.8 million
during the years ended December 31, 1995, 1996 and 1997, respectively.
 
 Revenue Recognition
 
  The Company's software products are licensed to customers through the
Company's direct sales force and by specific arrangements with certain
distributors, value-added resellers and other marketing representatives.
Revenue generated from licenses is recognized when the following criteria have
been met: (a) a written contract for the license of software has been
executed, (b) the Company has shipped the products to the customer, (c) the
fee is fixed or determinable, and (d) collectibility is probable. Revenues
recognized but not yet billed to customers total $103.1 million and $56.2
million, at December 31, 1996 and 1997, respectively. Unbilled revenue amounts
recorded at December 31, 1997 and expected to be collected subsequent to 1998
total $18.9 million.
 
  Revenue from maintenance contracts is recognized ratably over the term of
the agreement and is generally billed on a monthly basis. Deferred revenue is
recorded when upfront payments are received for annual maintenance
arrangements. Revenue from consulting, customer training and other services is
recognized as the service is performed.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Cost of Revenue
 
  The cost of software licenses primarily consists of the cost of distributing
the software products and an allocation of the amortization of capitalized
software development costs and royalty fees paid to third parties under
licensing agreements. Costs of maintenance and services primarily consist of
staff and related costs associated with the generation and support of software
service revenue and an allocation of the amortization of capitalized software
development costs and royalty fees paid to third parties under licensing
agreements. Management believes that the methodology for allocating the costs
is reasonable.
 
 Currency Translation
 
  Assets and liabilities of non-U.S. subsidiaries or divisions whose
functional currency is not the U.S. dollar are translated at current exchange
rates. Revenue and expense accounts are translated using an average rate for
the period. Translation gains (losses) are not included in determining net
income but are reflected as a component of Stockholder's Net Investment.
Cumulative currency translation adjustments included in Stockholder's Net
Investment were $1.1 million and $0.7 million at December 31, 1996 and 1997,
respectively. Foreign currency transaction gains (losses) were not material.
 
 Income Taxes
 
  The operations of the Company are included in EDS' consolidated income tax
returns. Current and deferred taxes have been allocated to the Company as if
taxes were computed on a stand-alone basis.
 
  Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for future tax consequences
attributable to differences between the financial statement carrying amounts
of existing assets and liabilities and their respective tax bases. Deferred
tax assets and liabilities are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period
that includes the enactment date. Tax benefits of operating losses and tax
credit carryforwards generated by the Company in foreign jurisdictions and
utilized by EDS to offset non-Company taxable income in such jurisdictions are
recognized by the Company as a reduction in Stockholder's Net Investment. See
Note 10 regarding the tax sharing agreement between the Company and EDS
effective January 1, 1998.
 
 Statements of Cash Flows
 
  The Company uses the indirect method to present cash flows from operating
activities and considers all highly liquid debt instruments with original
maturities of three months or less to be cash equivalents.
 
 Financial Instruments
 
  The carrying amounts of the Company's other financial instruments, including
cash and cash equivalents, trade accounts receivable, other current assets,
trade accounts payable, and accrued expenses approximate fair value because of
the short maturity of these instruments.
 
  The carrying amount and fair value of the Company's available-for-sale
marketable securities was $2.7 million at December 31, 1997. The estimated
fair value of the securities is based upon quoted market prices.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  At December 31, 1997, the Company also owned unvested warrants to purchase
447,091 shares of a public company for $0.11 per share. The warrants were
acquired in exchange for reduced royalty fees from a private software company
which was acquired by the public company in 1997. The warrants have a nominal
carrying value and vest over 8 years, or earlier if the acquired company's
revenues exceed predetermined amounts. The fair value of the underlying shares
to which these unvested warrants relate was $13.8 million at December 31,
1997.
 
 Significant Customers
 
  Effective July 1, 1996, the Company's parent, EDS, entered into a corporate
software license agreement with General Motors Corporation ("GM") which
provided for the delivery of various software products as well as the
provision of maintenance services for an initial term of three years. The
Company has agreed to perform EDS' obligation to provide products and services
under such agreement pursuant to a Memorandum of Understanding executed in
connection with the Reorganization.
 
  During the years ended December 31, 1995, 1996 and 1997, the portion of
Company revenues attributable to GM was 14%, 34%, and 6%, respectively. Other
than GM, no single customer accounted for more than 10% of the Company's
revenues in 1995, 1996 or 1997. Accounts receivable, including amounts
unbilled, from GM accounted for 54% and 48% of total accounts receivable in
1996 and 1997, respectively.
 
  Concentrations of credit risk with respect to accounts receivable are
limited due to the large number of customers constituting the Company's
customer base and their dispersion across different industry and geographic
areas. Accounts receivable are shown net of allowances of $4.9 million and
$5.4 million as of December 31, 1996 and 1997, respectively.
 
 Use of Estimates
 
  The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Because of the use of estimates inherent in the financial
reporting process, actual results could differ from those estimates.
 
  During 1995 and the period from January 1, 1996 through June 30, 1996,
Company billings to GM were included in the billings of EDS under a master
agreement that, prior to EDS' split-off from GM, served as a framework for
individual services agreements between GM and EDS. Management has estimated
that the Company's portion of GM revenues for 1995 and 1996 under EDS' master
service agreement with GM were $36.6 million and $21.4 million, respectively,
based on the number of workstations installed with Unigraphics software during
the year and average price per installed seat. Management believes that this
estimate is reasonable.
 
 Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of
 
  The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future undiscounted cash
flows expected to be generated by the asset. If such assets are considered to
be impaired, the impairment is measured by the amount by which the carrying
amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying amount or fair value
less cost to sell.
 
NOTE 2: RELATED PARTY TRANSACTIONS
 
  The Company utilized central cash management systems of EDS to finance its
operations. Cash requirements were satisfied either by intercompany
transactions between EDS and the Company or by cash from
 
                                      F-9

             (A SUBSIDIARY OF ELECTRONIC DATA SYSTEMS CORPORATION)
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
operations. Such intercompany transactions are included in the Stockholder's
Net Investment account in the balance sheets and as net cash advances to
affiliates in the statements of cash flows. Intercompany transactions between
EDS and the Company do not bear interest and therefore, no interest charge is
reflected in the accompanying statements of income.
 
  EDS provides services for the Company for management, accounting, human
resources, information systems, legal, taxes and other corporate activities.
Such corporate expenses amounting to $5.5 million, $8.6 million and $6.6
million have been allocated to the Company during the years ended December 31,
1995, 1996 and 1997, respectively, and are reflected in the accompanying
consolidated statements of income as selling, general and administrative
expenses. These costs were allocated to the Company by multiplying Company
revenues by a standard overhead rate for each period presented. The standard
overhead rate was developed through analysis of actual services and related
estimated costs provided to the Company on a historical basis. However, the
costs of these transactions may differ from those that would result from
transactions with unrelated parties.
 
  EDS has noncontributory defined benefit pension plans covering substantially
all of its employees, including employees of the Company. Costs related to
these plans are allocated to the Company based on the ratio of total payroll
dollars of the Company to total payroll dollars of EDS for the employee groups
of the respective plans and are included in selling, general and
administrative expenses. During the years ended December 31, 1995, 1996 and
1997, the Company recognized expense of $1.8 million, $2.4 million and $2.7
million, respectively, for such pension coverage. In accordance with the
provisions of the Management Services Agreement (Note 10), pension obligations
to Company employees under these plans at December 31, 1997 will be funded by
EDS.
 
  EDS has a deferred compensation plan which provides a long-term savings
program for U.S. employees, including employees of the Company. This plan
allows eligible employees to contribute a percentage of their compensation to
a savings program and to defer income taxes until the time of distribution.
EDS also offers a stock purchase plan which enables EDS employees to purchase
shares of EDS common stock at 85% of the quoted market price through payroll
deductions of up to 10% of their compensation.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  Tax benefits of operating losses and tax credit carryforwards totaling $2.5
million, $2.4 million and $1.9 million for the years ended December 31, 1995,
1996 and 1997 generated by the Company in foreign jurisdictions and utilized
by EDS to offset non-Company taxable income in such jurisdictions are
recognized by the Company as a reduction in Stockholder's Net Investment.
 
  In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred
tax assets will be realized. The ultimate realization of deferred tax assets
is dependent upon the generation of future taxable income during the period in
which those temporary differences become deductible. Management believes it is
more likely than not that the Company will realize the benefits of these
deductible differences.

a credit agreement established in connection with the Reorganization (the
"Intercompany Credit Agreement"). The cost of acquired companies is allocated
first to identifiable assets based on estimated fair values. Costs allocated
to identifiable intangible assets are amortized on a straight-line basis over
the remaining estimated useful lives of the assets as determined by underlying
contract terms or independent appraisals. Amounts allocated to in-process
research and development costs are expensed in the period of acquisition. The
excess of purchase price over the fair value of identifiable assets acquired,
net of liabilities assumed, is recorded as goodwill and amortized on a
straight-line basis over the useful life of five years. In connection with the
acquisition, the Company incurred a charge of $42.0 million relating to the
write off of acquired in-process research and development costs.
 
NOTE 10: REORGANIZATION AND AFFILIATE AGREEMENTS (UNAUDITED)
 
  The following transactions were consummated in connection with the
Reorganization:
 
  CAPITALIZATION--In addition to the $107.0 million borrowed under the
Intercompany Credit Agreement in connection with the Solid Edge Acquisition,
effective March 6, 1998, the Company issued to EDS as a dividend an
Intercompany Note in the principal amount of $73.0 million. The Intercompany
Note is payable on March 6, 2001 and bears interest, payable semiannually, at
a rate equal to the London Interbank Bid Rate ("LIBID") minus 0.5%. A portion
of the amounts advanced to the Company under the Intercompany Credit Agreement
in respect of the Solid Edge Acquisition is expected to be repaid to EDS with
the net proceeds of the initial public offering discussed under Note 11 (the
"Offering"). The Intercompany Credit Agreement restricts the Company from
obtaining financing from any party other than EDS without written consent from
EDS, unless EDS fails to provide funding available to the Company under the
Intercompany Credit Agreement.
 
  CASH AND CASH EQUIVALENTS--Effective with the Reorganization, the Company
began maintaining separate cash and investment accounts from EDS. Transactions
with EDS no longer result in immediate charges and credits to the Company's
cash equivalents, but are settled through intercompany billings. EDS manages
the Company's cash management system under the Management Services Agreement
discussed below.
 
  MANAGEMENT SERVICES AGREEMENT--The Company and EDS are parties to the
Management Services Agreement, effective as of January 1, 1998 (the
"Management Services Agreement") pursuant to which EDS performs various
management services for the Company including treasury, risk management and
tax, and similar administrative services, that EDS has historically provided
to the Company. Amounts charged to the

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
Company under this agreement approximate EDS' cost of providing the services
plus a fixed fee equal to 0.5% of the Company's total revenues. The Management
Services Agreement will expire on December 31, 2002 unless terminated earlier
by either party if EDS and the Company are no longer under common control.
Except for certain tax and treasury management services relating to
consolidated operations or corporate policy of EDS, which the Company is
required to purchase during the term of the Management Services Agreement, the
Company or EDS may terminate any service on or after January 1, 2000 with
prior notice of not less than five months.
 
  TAX SHARING AGREEMENT--The Company and EDS have entered into a tax sharing
agreement (the "Tax Sharing Agreement") which provides for the allocation of
tax liabilities during the tax periods the Company is part of consolidated
federal, state and local income tax returns filed by EDS. In addition, the Tax
Sharing Agreement sets out certain benefits and obligations of the Company and
EDS for tax matters relating to periods before the Reorganization and for
certain benefits and obligations that would affect the Company or EDS in the
future if the Company ceased to be a member of EDS's consolidated group for
federal income tax purposes. The Tax Sharing Agreement generally requires the
Company to pay EDS the amount of federal, state and local income taxes that
the Company would have been required to pay had the Company and its
subsidiaries filed their own tax return or returns and not been included in
the EDS consolidated group. The Company is jointly and severally liable for
the federal income tax of EDS and the other companies included in the
consolidated return for all periods in which the Company is included in the
EDS consolidated group. EDS has agreed, however, to indemnify the Company for
any liability for taxes reported or required to be reported on a consolidated
return.
 
  Except for certain items specified in the Tax Sharing Agreement, EDS
generally retains any potential tax benefit carryforwards, and remains
obligated to pay all taxes, attributable to periods before the Reorganization.
 
  CREDIT AGREEMENT--In order to allow EDS to manage efficiently the cash and
cash needs of its subsidiaries, the Company and EDS (or EDS Subsidiary, EDS
Finance plc, as the case may be) are parties to the Intercompany Credit
Agreement, pursuant to which the Company is required to borrow from EDS, and
EDS is required to lend to the Company, any amount required by the Company to
fund its daily cash requirements. In addition, EDS has made an advance to the
Company under the Intercompany Credit Agreement in the amount of $107.0
million in connection with the Solid Edge Acquisition, which advance will be
repaid upon consummation of the Offering. The maximum amount that the Company
may borrow at any time from EDS under the Intercompany Credit Agreement
(together with the other non-U.S. credit agreements referred to below) is
$177.0 million at any time prior to the closing of the Offering, or $70.0
million at any time thereafter. Also, under the Intercompany Credit Agreement,
the Company is required to lend to EDS all excess cash of the Company. The
interest rate to be charged to the Company is the sum of the one-month London
Interbank Offered Rate plus 0.5%. The interest rate to be charged to EDS is
the one-month LIBID minus 0.5%. On any business day that the Company has
excess cash available, it must use that cash to repay any outstanding loans it
has under the Intercompany Credit Agreement or make an advance to EDS if no
loans are outstanding. The Intercompany Credit Agreement will terminate on
December 31, 2002, unless earlier terminated at the election of one of the
parties upon the occurrence of certain events, including the termination of
the Management Services Agreement or the cessation of EDS' beneficial
ownership of 50% or more of the capital stock of the Company. In addition to
the Intercompany Credit Agreement between the Company and EDS, EDS Finance
plc, a wholly-owned subsidiary of EDS, has entered into or will enter into
credit agreements with substantially all non-U.S. subsidiaries of the Company
having terms similar to the Intercompany Credit Agreement.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  GM SUBCONTRACT--In connection with the Reorganization, EDS and the Company
entered into a Memorandum of Understanding, effective January 1, 1998 (the "GM
Subcontract"), pursuant to which the Company receives all revenues and
performs EDS' obligations under the EDS/GM Site License Agreement and agrees
to cooperate with EDS in providing additional products and services to GM
under the EDS/GM MSA. The GM Subcontract further provides that the Company may
provide directly to GM products and services that are outside of the scope of
the EDS/GM MSA.
 
  OTHER AGREEMENTS--In addition to the agreements set forth above, the Company
and EDS are parties to a Registration Rights Agreement described under "Shares
Eligible for Future Sale." The Company and EDS are also parties to various
subleases pursuant to which the Company subleases from EDS the real property
occupied by the Company prior to the Reorganization. The terms of these
sublease agreements incorporate the financial and other material terms of EDS'
lease agreements for the subject properties.. The Company also has, or expects
to enter into, other agreements with EDS or other EDS affiliates, pursuant to
which the Company does not expect to receive or pay material amounts.
 
  PENSION BENEFITS--The Company and EDS have entered into an agreement which
permits the employees of the Company to continue to participate in the benefit
plans and programs sponsored by EDS until the Company establishes separate
plans and programs for employees.
 
NOTE 11: PROPOSED PUBLIC OFFERING OF COMMON STOCK (UNAUDITED)
 
  On March 17, 1998, the Company's Board of Directors authorized management of
the Company to file a Registration Statement with the Securities and Exchange
Commission for an initial public offering of the Company's Class A Common
Stock. The Company contemplates using the proceeds from such offering to repay
indebtedness incurred in connection with the Solid Edge Acquisition.

                        REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Intergraph Corporation
 
  We have audited the accompanying statements of assets sold of the Solid Edge
and Engineering Modeling Systems Software Product Lines of Intergraph
Corporation (the Product Lines) as of December 31, 1996 and 1997 and the
related statements of revenues and direct expenses for each of the years in
the three-year period ended December 31, 1997. These statements are the
responsibility of the Product Lines' management. Our responsibility is to
express an opinion on the 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 statements are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the statements. An audit also
includes assessing the basis of accounting used and significant estimates made
by management, as well as evaluating the overall presentation of the
statements. We believe that our audits provide a reasonable basis for our
opinion.
 
  The Product Lines consist of products and services offered by various
subsidiaries and divisions of Intergraph Corporation and as such do not
constitute a separate legal entity. Accordingly, the statements of assets sold
and revenues and direct expenses of the Product Lines have been carved out
from the consolidated balance sheets and statements of operations of
Intergraph Corporation. Management believes the assumptions underlying the
statements of assets sold and revenues and direct expenses of the Product
Lines to be reasonable.
 
  As described in Note 1, the accompanying financial statements were prepared
for the purpose of complying with Rule 3-05 of Regulation S-X of the
Securities and Exchange Commission and are not intended to be a complete
presentation of assets and results of operations on a stand-alone basis of the
Product Lines.
 
  In our opinion, the statements referred to above present fairly, in all
material respects, the assets sold described in Note 2 of the Solid Edge and
Engineering Modeling Systems Software Product Lines of Intergraph Corporation
as of December 31, 1996 and 1997, and the revenues and direct expenses for
each of the years in the three-year period ended December 31, 1997 in
conformity with generally accepted accounting principles.

                                   EXPENSES
 
NOTE 1: ORGANIZATION, OPERATIONS, AND BASIS OF PRESENTATION
 
  "Solid Edge" and "Engineering Modeling Systems" ("EMS") software are
application specific software products developed, marketed, and sold by
Intergraph Corporation ("Intergraph") to end user customers for use in
automation of the design of mechanical parts and assemblies. The products are
sold by Intergraph through its direct sales force, its international
subsidiary companies, and through indirect channels including distributors,
business partners, and resellers.
 
  All significant intercompany accounts and transactions have been eliminated
in combination of the accompanying statements.
 
  Historically, financial statements have not been prepared for the Solid Edge
and EMS product lines as they do not represent a separate Intergraph legal
entity or line of business. The accompanying statements are derived from the
historical accounting records of Intergraph and its subsidiary companies, and
present assets sold relative to these product lines as of December 31, 1996
and 1997, and revenues and direct expenses of the product lines for the three
years in the period ended December 31, 1997. The Statements of Revenues and
Direct Expenses includes all revenues and expenses directly attributable to
the Solid Edge and EMS product lines for the periods presented. Direct
expenses consist principally of cost of sales, product development expenses,
and selling and marketing expenses. The Statements do not include general and
administrative expenses, general corporate overhead, interest expense, or
income taxes. These Statements are not intended to be a complete presentation
of Solid Edge and EMS financial position and results of operations had these
product lines operated as a stand alone entity, but were prepared for the
purpose of complying with Rule 3-05 of Regulation S-X of the Securities and
Exchange Commission. Historical operating results may not be indicative of
results after acquisition of these product lines by the buyer.
 
NOTE 2: ASSET PURCHASE AGREEMENT
 
  The accompanying statements have been prepared for the purpose of presenting
the assets sold pursuant to the Asset Purchase Agreement (the "Agreement")
between Intergraph Corporation and Unigraphics Solutions Inc. ("USI"), a
direct wholly owned subsidiary of Electronic Data Systems Corporation. Under
the Agreement, which was consummated March 2, 1998, USI purchased from
Intergraph for $105 million in cash certain of the assets of the Solid Edge
and EMS product lines, including:
 
    1) Intellectual property interests, including the outright purchase of
  the Solid Edge and EMS source code, trademarks, and copyrights unique to
  those products, and license agreements with Intergraph for source code,
  patents and patent applications, and software development tools common to
  the acquired products and other products not sold to USI.
 
    2) Contract rights, including customer contracts (except for certain
  contracts between Intergraph and the United States government and contracts
  for the sale and maintenance of software used in the design and
  manufacturing of structural support systems for ships and other marine
  vessels), distributor, business partner, and reseller contracts, and
  unfulfilled bids and sales orders with customers.
 
    3) Inventories and supplies.
 
    4) Computer hardware, office equipment, and furniture.
 
    5) Prepaid expenses and other assets.
 
  In addition, USI extended offers of employment to Intergraph employees
directly associated with the Solid Edge and EMS product lines.

                    NOTES TO STATEMENTS OF ASSETS SOLD AND
            STATEMENTS OF REVENUES AND DIRECT EXPENSES--(CONTINUED)
 
 
  Assets specifically retained by Intergraph and thus not included in the
accompanying statements include, in addition to those described in 1) and 2)
above, accounts receivable attributable to sales of the product lines up to
the March 2, 1998 closing date, contracts related to real property associated
with the product lines, and certain contracts for third party software
utilized in the product lines.
 
  Liabilities of the product lines assumed by USI are limited to those arising
subsequent to the date of closing under the assumed contracts described above.
All liabilities arising from the operations of the product lines prior to the
closing date, or relating to any of the assets retained, were retained by
Intergraph.
 
NOTE 3: SIGNIFICANT ACCOUNTING POLICIES
 
  Revenue Recognition: Revenues from software sales with no significant post-
shipment obligations are recognized as software is shipped, with any post-
shipment costs accrued at that time.
 
  Maintenance and services revenues are recognized ratably over the lives of
the maintenance contracts or as services are performed.
 
  Billings may not coincide with the recognition of revenue. Unbilled accounts
receivable occur when revenue recognition precedes billing to the customer,
and arise primarily from sales with predetermined billing schedules. Billings
in excess of sales occur when billing to the customer precedes revenue
recognition, and arise primarily from maintenance revenue billed in advance of
performance of the maintenance activity.
 
  Inventories: Inventories are stated at the lower of average cost or market.
 
  Computer Hardware, Office Equipment, and Furniture: Computer hardware,
office equipment, and furniture is stated at cost. Depreciation is provided
using the straight line method over estimated useful lives ranging from three
years for computer hardware and office equipment to eight years for certain
items of furniture.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a Delaware corporation may indemnify directors and
officers and certain other individuals against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by any such person in connection with any threatened, pending or
completed action, suit or proceeding (other than an action by or in the right
of the corporation) in which such person is involved because such person is a
director or officer of the corporation, if such person acted in good faith and
in a manner that such person reasonably believed to be in or not opposed to
the best interests of the corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe that such person's conduct
was unlawful. No indemnification shall be made to an officer or director or
other qualified individual if such person shall have been adjudged to be
liable to the corporation unless such person acted in good faith and in a
manner that such person reasonably believed to be in or not opposed to the
best interest of the corporation and only to the extent the Court of Chancery
of the State of Delaware or the court in which such action or suit was
brought, determines that despite the adjudication of liability such person is
fairly and reasonably entitled to such indemnification. If such person is
successful on the merits or otherwise in defense of any action, then Section
145 provides that such person shall be indemnified against expenses including
attorneys' fees actually and reasonably incurred by that person in connection
therewith. Section 102(b)(7) of the DGCL provides that the liability of a
director may not be limited or eliminated for the breach of such director's
duty of loyalty to the corporation or its stockholders, for such director's
intentional acts or omissions not in good faith, for such director's
concurrence in or vote for an unlawful payment of a dividend or unlawful stock
purchase or redemption or for any improper personal benefit derived by the
director from any transaction.
 
 
                                     II-1
<PAGE>
 
  The Company's Bylaws provide that the Company will indemnify any person who
was or is a party (or is threatened to be made a party) to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he or she is or
was or has agreed to serve at the request of the Company as a director or
officer of the Company, or is or was serving or has agreed to serve at the
request of the Company as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or by reason of any
action alleged to have been taken or omitted in such capacity. The Company's
Bylaws further provide that the Company may indemnify any person who was or is
a party (or is threatened to be made a party) to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that he or she is or was or has agreed
to become an employee or agent of the Company, or is or was serving or has
agreed to serve at the request of the Company as an employee or agent of
another corporation, partnership, joint venture, trust or other enterprise, or
by reason of any action alleged to have been taken or omitted in such
capacity.
 
  The indemnification referred to in the preceding paragraph will be from and
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by the indemnitee or on
his or her behalf in connection with such action, suit or proceeding and any
appeal therefrom. However, such indemnification will only be provided if the
indemnitee acted in good faith and in a manner he or she reasonably believed
to be in or not opposed to the best interests of the Company and, with respect
to any criminal action, suit or proceeding, had no reasonable cause to believe
his or her conduct was unlawful. Notwithstanding the preceding two sentences,
in the case of an action or suit by or in the right of the Company to procure
a judgment in its favor (a) the indemnification referred to in this paragraph
will be limited to expenses (including attorneys' fees) actually and
reasonably incurred by such person in the defense or settlement of such action
or suit, and (b) no indemnification will be made in respect of any claim,
issue or matter as to which such person will have been adjudged to be liable
to the Company unless, and only to the extent that, the Delaware Court of
Chancery (or the court in which such action or suit was brought) determines
upon application that, despite the adjudication of liability but in view of
all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Delaware Court of Chancery
(or such other court) deems proper. To the extent that a director, officer,
employee or agent of the Company has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to above or in
defense of any claim, issue or matter therein, he or she will be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him or her in connection therewith. Expenses incurred by a director or
officer in defending a civil or criminal action, suit or proceeding will be
paid by the Company in advance of the final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of the director
or officer to repay such amount if it will ultimately be determined that he or
she is not entitled to be indemnified by the Company. Such expenses incurred
by other employees and agents may be so paid upon such terms and conditions,
if any, as the Board of Directors deems appropriate.
 
  The indemnification described in the preceding two paragraphs will not be
deemed exclusive of any other rights to which those indemnified may be
entitled under any Bylaw, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his or her official capacity and
as to action in another capacity while holding such office, will continue as
to a person who has ceased to be a director, officer, employee or agent and
will inure to the benefit of the heirs, executors and administrators of such a
person.
 
  The Company will maintain insurance on behalf of any person who is or was or
has agreed to serve at the request of the Company as a director or officer of
the Company, or is or was serving at the request of the Company as a director
or officer of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against, and incurred by, him or her
or on his or her behalf in any such capacity, or arising out of his or her
status as such, whether or not the Company would have the power to indemnify
him or her against such liability under the provisions of the Bylaws;
provided, however, such insurance must be available on acceptable terms, which
determination shall be made by a vote of a majority of the Board of Directors.

 UNDERWRITING AGREEMENT
 
  The Underwriting Agreement, the form of which is filed as Exhibit 1.1 to the
Registration Statement, provides for the indemnification of the directors and
officers of the Company against certain liabilities, including liabilities
arising under the Securities Act.
 
  The above discussion of the Certificate of Incorporation, Bylaws,
Underwriting Agreement and Section 145 of the DGCL is not intended to be
exhaustive and is respectively qualified in its entirety by the Certificate of
Incorporation, Bylaws, Underwriting Agreement and such statute.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  In connection with its formation on October 2, 1997, the Company issued 500
shares of common stock to EDS in consideration for a cash payment of $1,000.
Effective January 1, 1998 the Company issued an additional 500 shares of
common stock to EDS in consideration for the assets transferred to the Company
in connection with the Reorganization. Effective March 6, 1998, the Company
issued as a dividend a $73 million Intercompany Note to EDS. Prior to the
consummation of the Offering the 1,000 shares of common stock will be
reclassified into     shares of Class B Common Stock. Based on the
relationship between the Company and EDS and other factors, the Company
believes that these issuances and distributions were exempt from registration
under the Securities Act.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
  The undersigned Registrant also undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in the form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of the
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and this offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

Section 2.5 or in any Closing Agreement) or to satisfy any conditions precedent

Agreement, including without limitation those rights set forth in Section 9.2.

     2.11 Customer Contracts.
          ------------------   

     (a)  As soon as practicable following the Principal Closing Date, the
applicable Selling Entity and the applicable Acquiring Entity shall jointly
notify each customer under a Customer Contract (other than those identified on
Section 2 of Schedule 3.23(a) which are being assigned to the Acquiring
             ----------------                                          
Entities) that effective as of the Principal Closing Date the Business has been
transferred to the Acquiring Entities pursuant to this Agreement, and such
Selling Entity shall use its best efforts to assist the applicable Acquiring
Entity in obtaining a successor Customer Contract with the applicable Acquiring
Entity with respect to the products and services of the Business on
substantially the same terms as the Customer Contract (a "Successor Customer
Contract").  In the event that a Successor Contract is not entered into by the
customer and the applicable Acquiring Entity under terms acceptable to both
Persons prior to the termination of a Customer Contract (under the current terms
of the Customer Contract without giving effect to any automatic renewal or
"evergreen" provisions thereof), the applicable Selling Entity shall continue
the performance of such Contract as contemplated in Section 2.11(b) below.

     (b)  During the period from the Principal Closing Date through the earlier
of (i) the termination of a Customer Contract under the terms thereof (not
giving effect to any automatic renewal provisions thereof) and (ii) the date a
Successor Contract to a Customer Contract is entered into between the customer
and an Acquiring Entity as contemplated by Section 2.11(a) above (such period
being referred to hereinafter as the "Subcontract Period"), Intergraph and each
other applicable Selling Entity shall cause the benefits of their respective
right, title and interest (or the economic equivalent thereof) under such
Customer Contracts to be provided to the applicable Acquiring Entity and shall
cooperate with such Acquiring Entity to provide such Acquiring Entity with such
benefits, which cooperation shall include without limitation: (A) maintenance by
Intergraph and each other applicable Selling Entity of rights under such
Customer Contract in their name in trust for the benefit of such Acquiring
Entity; (B) payment to the applicable Acquiring Entity of amounts collected in
respect of such Customer Contract as follows: for payments received by a Selling
Entity during March 1998, by wire transfer to an account designated by USI not
later than 12:00 noon on the Wednesday following the week during which such
payment was received by a Selling Entity; and for payments received by a Selling
Entity after March 1998, by wire transfer to an account designated by USI not
later than 12:00 noon on the second Business Day following receipt thereof; and
(C) at the sole option and subject to the control of such Acquiring Entity,
enforcement for its benefit of any and all such rights against a third party in
the event such rights can not be enforced by the Acquiring Entity.  Unless not
permitted under any Assumed Contract with respect to which rights are made
available to an Acquiring Entity and except to the extent contemplated by the
Version 4 Reseller Agreement, the performance of such Selling Entity's
obligations thereunder shall be subcontracted or sublicensed to such Acquiring
Entity from the time such rights are made available to such Acquiring Entity
through the termination of the Subcontract Period and the applicable Acquiring
Entity shall perform such obligations in accordance with their terms.  If such
assignment, subcontracting or sublicensing is not permitted, such Acquiring
Entity will use commercially reasonable efforts to perform and complete such
Assumed Contract in accordance with its terms from and after the time such
rights are made available; provided, 
                           --------  

                                      25
<PAGE>
 
however, that in connection with the foregoing, such Acquiring Entity shall have
- -------
all rights and remedies against the other party to such Assumed Contracts,
including without limitation the right to cease providing products and services
thereunder if the other party thereto fails to perform its obligations
thereunder.

     (c)  Intergraph shall deliver to USI amounts prepaid under Prepaid
Maintenance Contracts in respect of the period following the applicable Closing
Date as follows: (i) concurrently with the applicable Closing, Intergraph shall
deliver to USI the amounts prepaid under such Contracts in respect of the month
in which such Closing occurs (pro-rated from the applicable Closing Date); and
(ii) on the first day of each month thereafter, Intergraph shall deliver to USI
the amounts prepaid under such Contracts in respect of each such month.

     2.12 Distributor Contracts.  Prior to the Principal Closing Date, the
          ---------------------                                             
Selling Entities shall use their best efforts to amend each Distributor Contract
to remove therefrom the products and services of the Business and, except with
respect to such Distributor Contracts covering a territory or territories
outside of the United States identified on Schedule 2.12, to enter into a
                                           -------------                 
separate successor distributor contract (a "Successor Distributor Contract")
covering the products and services of the Business on terms reasonably
acceptable to USI.  For purposes of this Agreement, terms consistent with those
contained in the existing Distributor Agreement shall be deemed to be reasonably
acceptable to USI.  Each Successor Distributor Agreement shall be assignable to
USI or another applicable Acquiring Entity effective as of the Principal Closing
Date and shall be assigned at the Closing and be an Assumed Contract hereunder
(subject to the proviso set forth in the definition of "Assumed Contract" in
Section 1.1).

     2.13 Consents.  The parties will cooperate with each other in good
          --------                                                        
faith to timely obtain all Consents from any and all Tribunals and other Persons
that are required (i) for the consummation of the transactions contemplated by
this Agreement; (ii) to permit the continued operation of that portion of the
Business conveyed on any Closing Date on or after such Closing Date in
substantially the same manner as it was carried on and conducted prior thereto,
including, without limitation, the execution of Successor Contracts pursuant to
Section 2.12 hereof; and (iii) to prevent a breach of, a default, penalty or
increase in payment under, or a termination of any Contract relating to the
Business.  The cost of obtaining such Consents shall be borne by the party who
is required to obtain such Consent under the applicable Legislative Enactment or
under the terms of the relevant Contract, provided, however, that if the
applicable Legislative Enactment does not provide which party shall pay such
costs, the costs shall be borne equally by USI and Intergraph (although in all
cases each party shall pay the fees and expenses of its own counsel). The
parties hereto agree to use their best efforts to obtain such Consents in a cost
effective and efficient manner.  Until all Consents referenced in this Section
                                                                       -------
2.13 are obtained, the applicable Selling Entities shall provide the applicable
- ----                                                                           
Acquiring Entity with the rights and benefits, and the Selling Entities shall in
any event continue to have the indemnity and hold harmless obligations set forth
in Article IX.

     2.14 Interim Operation for International Selling Entities.
          ---------------------------------------------------- 

     (a)  With respect to each International Selling Entity that does not
transfer and convey all of its respective portion of the Business and Acquired
Assets on the Principal Closing Date, 

                                      26
<PAGE>
 
from and after the Principal Closing Date USI may, at its option, designate one
or more employees or other representatives of the Acquiring Entities to serve as
managers of the Business of each such International Selling Entity to the extent
permitted by applicable law. The management of the Business of each respective
International Selling Entity shall report to, and be subject to the direction
of, such manager so designated by the Acquiring Entities. Such managers may
serve their functions on-site at such International Selling Entities. The
Acquiring Entities shall be free to make oral and written communications to the
employees of the International Selling Entities during the period following the
Principal Closing Date (provided that communications describing the terms of
this Section 2.14(a) shall be provided to Intergraph in advance of their release
for their prompt comment and review). During this period, USI may request that
the employment of any employee of the International Selling Entity who would be
a Transitioned Employee be terminated. In such event, no later than five days
following the date of such request Intergraph may either (i) continue the
employment of such person for Intergraph's benefit (which continuation would not
be a violation of Section 5.7 hereof), in which event USI shall not be obligated
to reimburse USI for such person's salary upon the occurrence of the applicable
International Closing, or (ii) terminate the employment of such person, in which
event USI will reimburse Intergraph for any required severance payments to any
such employee in accordance with Intergraph's severance policy.

     (b)  From and after the Principal Closing Date, the Business of each
International Selling Entity shall be conducted and operated for the account and
benefit of the applicable Acquiring Entities.  At the applicable International
Closing for an International Selling Entity, the Closing Agreement shall provide
for (i) the payment by the applicable Selling Entity to the applicable Acquiring
Entity of all revenues derived by the portion of the Business attributable to
such Selling Entity (which revenues shall have been collected by the Selling
Entities and held for the benefit of the applicable Acquiring Entity) during the
period from and after the Principal Closing Date to the date of the applicable
International Closing (the "Interim Period"), (ii) the reimbursement by the
applicable Acquiring Entity to the applicable Selling Entity of all expenses
directly attributable to the operation of the Business by such Selling Entity
during the Interim Period (and excluding any expenses attributable to any other
business or businesses of the Selling Entities), including, without limitation,
costs and expenses associated with employment of the Transitioned Employees and
Taxes (other than Transaction Taxes) attributable to the operation of the
Business during the Interim Period, and (iii) the payment of any excess of the
amount described in clause (i) over the amount described in clause (ii) (a
"Profit Amount") from the applicable Selling Entity to the applicable Acquiring
Entity, or the payment of any excess of the amount described in clause (ii) over
the amount described in clause (i) (a "Loss Amount") from the applicable
Acquiring Entity to the applicable Selling Entity. The payment of any Profit
Amount or Loss Amount, as the case may be, shall be treated as an adjustment to
the Consideration payable in respect of such International Closing.  Not later
than 15 Business Days following the applicable International Closing, the
applicable Selling Entity and Acquiring Entity shall adjust the Profit Amount or
Loss Amount, as the case may be, based on any revenues or expenses which were
unidentified at the time of the International Closing and, based on such post-
closing adjustment, any excess amounts delivered at the applicable International
Closing pursuant to the immediately preceding sentence shall be immediately
returned and/or any additional payments which would be required to have been
made at such International Closing pursuant to such sentence shall be
immediately paid by the applicable party. At an International Closing, the
applicable Selling Entity shall deliver to the applicable Acquiring Entity cash
in an


                                      27
<PAGE>
 
amount equal to the accrued liability of such Selling Entity in respect of
employee benefits (such as severance, termination indemnities or vacation) which
benefits are required to be assumed by the Acquiring Entity as a matter of
applicable law, except to the extent that such liabilities are settled directly
with the relevant employees at the applicable Closing or are governed by Section
5.13(h) hereof.

     (c)  USI and Intergraph will use their commercially reasonable best efforts
to consummate all International Closings as soon as practicable following the
Principal Closing Date. Until such time as all International Closings have been
consummated, USI and Intergraph shall cause their representatives to confer
frequently (and in any event not less frequently than monthly) with each other
regarding the status of such International Closings.


                                  ARTICLE III
            REPRESENTATIONS AND WARRANTIES OF THE SELLING ENTITIES

     To induce the Acquiring Entities to enter into this Agreement and to
consummate the transactions contemplated hereby, the Selling Entities jointly
represent and warrant to the Acquiring Entities as follows and as may be
additionally provided in the applicable Closing Agreement:

     3.1  Corporate Existence and Authority.  Each Selling Entity is a
          ---------------------------------                             
corporation or other legal entity (as indicated on Schedule 3.1) duly organized,
                                                   ------------                 
validly existing and to the extent such a concept or a similar concept exists in
the relevant jurisdiction, in good standing under the laws of the state or other
jurisdiction of its incorporation or other organization, as set forth on
                                                                        
Schedule 3.1. Each Selling Entity has all requisite power and authority to own
- ------------                                                                  
and lease its properties and assets and to carry on the Business, as such
business is being conducted currently.  Schedule 3.1 contains a true, complete
                                        ------------                          
and correct list of all jurisdictions in which any of the Selling Entities owns
or leases any real property or has employees or offices relating to the
Business.  Each Selling Entity is duly qualified and licensed to do business as
a foreign corporation or entity and is in good standing in all jurisdictions in
which the nature of the business being conducted requires it to be so qualified
except where the failure so to qualify may reasonably be expected not to have a
material adverse effect on the Business or the Acquired Assets, taken as a
whole.

     3.2  Authorization and Effect of Agreement, Etc.  Each Affiliate of
          ------------------------------------------                      
Intergraph whose action is legally required to transfer to the Acquiring
Entities the Acquired Assets in accordance with this Agreement is listed as a
Selling Entity on the signature pages hereof. Each Selling Entity has all
requisite power and authority to enter into, execute and deliver this Agreement
and the other agreements contemplated hereby to which such Person is a party and
to perform its obligations hereunder and thereunder and to consummate the
respective transactions contemplated hereby and thereby for such Selling Entity.
The execution, delivery and performance of this Agreement by each of the Selling
Entities and the other agreements contemplated hereby to which such Person is a
party and the consummation by the Selling Entities of the transactions
contemplated hereby and thereby have been duly authorized by all corporate and
other entity action. This Agreement has been, and the other agreements
contemplated hereby to which any of the Selling Entities is a party will be,
duly executed and delivered by each of the Selling Entities (to the extent such
Person is a


                                      28
<PAGE>
 
party thereto) and constitute, or when executed and delivered will constitute,
the valid and binding obligation of the Selling Entities, enforceable in
accordance with its respective terms, except that (a) such enforcement may be
subject to bankruptcy, insolvency, reorganization, moratorium or other similar
Legislative Enactments now or hereafter in effect relating to creditors' rights
generally, and (b) the remedy of specific performance and injunctive relief may
be subject to equitable defenses and to the discretion of the court before which
any proceeding may be brought. This Agreement, the General Bill of Sale, the
Copyright Assignment, the Trademark Assignment, the Transferred Intellectual
Property License Agreements and the Closing Agreements, when executed and
delivered by the respective Selling Entities, will be sufficient to assign,
convey, transfer, vest, perfect and confirm in the appropriate Acquiring
Entities, good and marketable title in and to the Acquired Assets.

     3.3  No Violation.  Except as set forth on Schedule 3.3, neither the
          ------------                          ------------

Agreement or of any other agreement contemplated hereby to which any of such
Persons is a party, nor the consummation by any of the Selling Entities of any
of the transactions contemplated hereby or thereby in accordance with the terms
hereof or thereof does or will (with the passage of time, the giving of notice
or otherwise), with respect to any Selling Entity (a) violate or conflict with
any provision of the Charter, Bylaws or other governance document of such
Selling Entity; (b) violate, conflict with, modify or cause any default under or
acceleration of (or give any party any right to declare any default or
acceleration, upon notice or passage of time or otherwise with respect to), in
whole or in part, any Contract related to the Business to which such Selling
Entity is a party or by which such Selling Entity or any of the Acquired Assets
is bound; (c) violate, conflict with or cause any default under (or give any
party any right to declare any default, upon notice or passage of time or
otherwise, under) any Legislative Enactments, Official Actions or any other
restriction of any kind or character to which such Selling Entity is a party or
by which such Selling Entity or any of its respective properties or any of the
Acquired Assets is bound; (d) result in the creation or imposition of any Lien,
proscription or restriction on any of the Acquired Assets; or (e) permit any
Tribunal to impose any material restrictions or limitations of any nature on
such Selling Entity or its properties or activities.

     3.4  Consents.
          --------   

     (a)  Except as set forth in Schedule 3.4(a), no Consent of, or
                                 ----------------

Entity in connection with the execution, delivery and performance by any of the
Selling Entities of this Agreement or the other agreements contemplated hereby
or the consummation of the transactions contemplated hereby or thereby in

     (b)  After the Principal Closing, except with respect to those Acquired
Assets to be transferred at each International Closing (and with respect to such
Acquired Assets, after such International Closing related thereto) and except as
set forth on Schedule 3.4(b), the Acquiring Entities shall have the unrestricted
             ---------------                                                    
right to own, use, operate and sell all or any of the Acquired Assets and to
conduct the Business as it is currently conducted by the Selling Entities
without the payment of any royalty, license or other fee to any Person by USI or
any Affiliate of USI, including


                                      29
<PAGE>
 
without limitation any transfer fee, relicensing fee or other fee with respect
to Software to be transferred or assigned.

     3.5  General Warranty.  All written statements, certificates or documents
          ----------------                                                      
furnished by any Selling Entity in accordance with this Agreement, taken as a
whole, are true, complete and correct in all material respects and do not
contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements contained herein or therein, in
light of the circumstances under which they were made, not misleading, provided,
however, that the only representation or warranty made with respect to the
Projections is the representation and warranty set forth in Section 3.30.

     3.6  Challenges To This Agreement.  No suit, action, proceeding or
          ----------------------------                                   
investigation against any Selling Entity challenging this Agreement or any of
the transactions contemplated hereby or claiming damages in connection with this
Agreement or any of the transactions contemplated hereby has been instituted or,
to the knowledge of the Selling Entities (without independent investigation),
threatened.

     3.7  Financial Statements.  The Selling Entities have provided to USI
          --------------------                                              
true, complete and correct copies of the Financial Statements, which are
attached hereto as Schedule 3.7.  The Financial Statements fairly present,
                   ------------                                           
except for the presentation of footnote disclosures (which footnote disclosures
are not material to an understanding of the Financial Statements) which will be
provided as soon as practicable following the Principal Closing pursuant to
Section 5.6 hereof, the financial position of the Selling Entities with respect
to the Business and the related results of operations at the dates and for the
periods covered thereby, subject with respect to quarterly financial information
to normal, recurring year-end audit adjustments described in Section 1 of
                                                             ---------   
Schedule 3.7.  The Financial Statements have been prepared in accordance with
- ------------                                                                 
GAAP, other than the aforementioned footnote disclosures, applied on a
consistent basis during the periods involved.  As of the Balance Sheet Date, (A)
none of the Selling Entities had any liability or expense of any nature, whether
accrued, absolute, contingent or otherwise, and whether due or to become due,
with respect to the Business which was not reflected in the Financial Statements
and which was of a nature required under GAAP to be reflected in the Financial
Statements or disclosed in the notes thereto when prepared, (B) all allowances
and reserves set forth in the Financial Statements were adequate for the
respective purposes for which they were established, and (C) there were no loss
contingencies (as such term is used in Statement of Financial Accounting
Standards No. 5) or contingent liabilities which were of a nature required under
GAAP to be reflected or disclosed and were not reflected in the Financial
Statements or will be disclosed in the notes thereto.  Since the Balance Sheet
Date, except for liabilities that have been incurred in the ordinary course of
the Business consistent with past practices, none of the Selling Entities has
incurred any material liability of any nature (whether accrued, absolute,
contingent or otherwise) with respect to the Business. Except as set forth in
Schedule 3.7(a), none of the Selling Entities is liable upon or with respect to,
- ---------------                                                                 
or obligated in any other way to provide funds in respect of or to guarantee or
assume in any manner, any debt, obligation or dividend of any Person related to
the Business.  The Financial Statements fairly reflect the liabilities accrued
for the annual incentive compensation benefits payable under the plans and
programs set forth in Schedule 3.25(c), consistent with prior application of the
                      ----------------                                          
terms of such plans and taking into account performance to date.


                                      30

     3.8  Accounts Receivable.  All of the Accounts Receivable reflected in
          -------------------                                                
the Balance Sheet have arisen in connection with bona fide sales and deliveries
of goods, performance of services or other bona fide business transactions in
the ordinary course of the Business, consistent with past practices (including
regular credit practices). All reserves reflected in the Balance Sheet against
doubtful accounts of, valid counterclaims or setoffs by, rebates, discounts and
allowances to, and returns from, customers were established in a manner
consistent with the collection experience of the Business in prior year s.

     3.9  Customer Discounts.  Except as set forth on Schedule 3.9, since
          ------------------                          ------------       
December 31, 1996, no Selling Entity has granted any rebates, discounts,
advances or allowances to any customers of the Business for products or
services, except in the ordinary course of business consistent with past
practice.

     3.10 SEC Reports.  Intergraph has previously furnished to USI true,
          -----------                                                     
complete and correct copies of Intergraph's (i) Annual Report on Form 10-K for
the year ended December 31, 1996, and (ii) Quarterly Reports on Form 10-Q for
the quarters ended March 31, June 30, and September 30, 1997, each as filed with
the SEC. As of their respective filing dates and to the extent such reports and
statements relate to the Business, such reports and statements complied in all
material respects with all applicable requirements of the Exchange Act and the
rules and regulations promulgated thereunder, and such reports and statements as
of the date of their respective filing did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

     3.11 Absence of Changes.  Except as set forth in Schedule 3.11, since
          ------------------                          -------------       
December 31, 1997 there has not been, occurred or arisen any change in, or any
event (including without limitation any damage, destruction or loss whether or
not covered by insurance), condition or state of facts of any character that
individually or in the aggregate has or may be expected to have a material
adverse effect on the Acquired Assets or the Business, taken as a whole.  Since
December 31, 1997, except as set forth in Schedule 3.11: (a)  no Selling Entity
                                          -------------                        
has taken or failed to take any action the taking of which or failure of which
to take, as the case may be, would have violated any of the provisions of
Sections 5.2 or 5.3 if they had then been applicable to any portion of the
- ------------    ---

Records with respect to the Business which, in reasonable detail, accurately and
fairly reflect in all material respects its transactions and the acquisitions

accordance with the general or specific authorization of its management, (b)
transactions are recorded as necessary to permit the preparation of financial
statements in conformity with GAAP and to maintain accountability for its
assets, (c) access to its assets is permitted only in accordance with the

accountability for its assets is

                                      31

compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences. No Selling Entity has used any

practices for the purposes of deceptively reflecting or not reflecting any of
its properties, assets, liabilities, revenues or expenses in any of its Books
and Records.

jurisdiction.

     (d)  Intergraph, Intergraph (Deutschland) GmbH, and Intergraph (Italia)
L.L.C. are neither presently under examination by any tax authorities, nor in

best knowledge of Intergraph, threatened, examinations, audits, investigations,
suits, or other legal proceedings involving, or material assessments against,
Intergraph, Intergraph (Deutschland) GmbH, or Intergraph (Italia) L.L.C. with
respect to Taxes attributable to the Business, or any other material claims for
unpaid Taxes attributable to the Business, which have been or may be asserted
against any of those entities.

     (e)  There are no pending or threatened audits, investigations,
examinations, suits or other legal proceedings involving, or material
assessments against, any Selling Entity with respect to Taxes attributable to

timely withheld or collected and, to the extent required, have been timely paid,
remitted or deposited to or with the relevant Tax Tribunal.

with respect to all Selling Entities.

and supplies that are reflected in the Balance Sheet were in good condition,
priced at the lower of cost (on the first-in, first-out basis) or market, and
(as to classes of items inventoried and methods of accounting and pricing)
determined in a manner consistent with prior years.  All of such inventories and

<PAGE>
 
purchased or acquired in the ordinary course of the Business, consistent with
past practices. All of the inventory included in the Acquired Assets is in good
condition and is not obsolete or defective. Purchase commitments for merchandise
are not in excess of normal requirements and are not at prices in excess of
market prices. The Selling Entities have the types and quantities of inventory
appropriate, taken as a whole, to conduct the Business in accordance with past
practices.

     3.28 Master Purchase Agreements.  Schedule 3.28 sets forth a true and
          --------------------------   -------------                      
correct list of those vendor agreements under which the Selling Entities make
purchases principally related to the Business (excluding those that relate to
assets or services furnished by Intergraph for the benefit of all of its
business units, subsidiaries or divisions and not principally to the Business,
including, without limitation, accounting and legal support and the services
provided under the Transition Services Agreement) (the "Master Purchase
Agreements").

     3.29 Compliance with Law.  To the best knowledge of the Selling
          -------------------                                         
Entities, without independent investigation, each of the Selling Entities (a)

its respective portion of the Business or the Acquired Assets, and (b) has duly
and timely made all filings and submissions that are required by Legislative
Enactments to be made with respect to such portion of the Acquired Assets or
such Business, and has provided the Acquiring Entities copies of all such
filings and submissions that have been made since January 1, 1993.

     3.30 Projections.  The financial projections for the Business prepared

prepared in good faith and, when prepared and furnished to USI, were based
solely upon assumptions that Intergraph believed to be reasonable. None of the
Selling Entities has any reason to believe that the Business will not so
substantially achieve the results described in the Projections (other than the
fact that the Business has not substantially achieved such results through the
date hereof and that the failure to achieve such results may impact the ability
of the Business to timely achieve the results described in the Projections),
although no assurance is given that the results set forth therein will be
achieved or that actual results will not differ materially from the results
reflected therein.

     (d)  Except as permitted under the EMS License Agreement or the SolidEdge
License Agreement, Intergraph will not copy, maintain, store, or archive any
computer software source code provided in the assets transferred to Unigraphics
by the concurrently executed Bill of Sale. Furthermore, except as contemplated
by the EMS License Agreement and the SolidEdge License Agreement, Intergraph
agrees that it will not have any access whatsoever to any such computer software
source code except through Unigraphics who has sole discretion whether to grant
such access.

     (e)  No Software comprising a part of the Business (1) contains any coded
instructions, routine, or other means (including but not limited to any back
door) that would enable any person or computer system, including authorized or
unauthorized users, to bypass any log-in and/or any security feature of the
Software or any computer on which the Software is installed; (2) contains any
coded instructions, routine or other means (including but not limited to any
time bomb or drop dead device) that, when activated in accordance with a
predetermined method, date, or event, causes the Software to cease to operate,
to operate in a degraded manner,

to damage or destroy data or code, or otherwise deleteriously affect the
functioning of the Software, other programs, or the computer systems on which
the Software is installed, or with which such computer systems are in
communication (except demonstration versions or copies of Software which cease
to function at a predetermined date if not purchased or if other similar action
is not taken); (3) contains any coded instructions, routine or other means that
causes the Software, other software, or the computer system on which the

     3.33 Development and Protection of the Owned IP.
          ------------------------------------------   

     (a)  The Owned IP consists exclusively of "works made for hire" as that 
term is used in Title 17 of the United States Code, and a Selling Entity is
considered the author of each of such works. The Owned IP was developed entirely
by (i) full time employees working within the scope of their employment within
the meaning of 17USC(S)101 of a Selling Entity during the period (for each such
person, his "Engagement Period") in which either (I) (A) he was a full time
employee of a Selling Entity, (B) he was employed only by a Selling Entity and
(C) he was expressly employed for the purpose of or his written job description
in the employment of a Selling Entity at the time of such actions included as a
primary duty the development of part of the Owned IP or (II) he was subject to a
valid and enforceable written Contract (an "Employee IP Contract") which
assigned to such Selling Entity ownership of the work or works produced,
including, without limitation, all intellectual property rights therein (such
employee, solely when meeting all of these criteria, referred to as a
"Developer"), or (ii) independent contractors or consultants engaged by a
Selling Entity which have assigned to such Selling Entity their entire right,
title, and interest in and to the work or works produced, including without
limitation all intellectual property rights therein pursuant to a valid and
enforceable written Contract (an "Independent Contractor IP Contract") (such
contractor or consultant meeting these criteria also referred to as a
"Developer"). No material Owned IP includes (i) any Intellectual Property in
which any Person other than a Selling Entity has or may acquire any right of
ownership, control or compensation, or (ii) any invention made by (A) any
employee of a Selling Entity who was not hired to invent at any time other than
during his Engagement Period or (B) any independent contractor or consultant
engaged by a Selling Entity who is not subject to an Independent Contractor IP
Contract, or (iii) the product of any effort to develop independently, through a
"clean room" effort or otherwise, an expression in which any Person other than a
Selling Entity has intellectual property rights. None of the Owned IP is the
product of a joint invention or authorship by a Developer and any Person who is
not also a Developer. No right of any Person other than a Selling Entity to any
patent, patent application, Trademark or Copyright is embodied in any of the
Owned Software, except as set forth on Schedule 3.33(a).
                                       ---------------- 
     (b)  Each Selling Entity has diligently taken reasonable measures to 
protect for the sole use and benefit of the Selling Entities the confidential
and proprietary nature of the Trade Secrets and the source code, object code and
access codes for the Software (the "Confidential Software"). Each Person,
including without limitation employees, agents, consultants, distributors and
licensees of the Selling Entities, who has had access to or otherwise been
exposed to any of the Trade Secrets or Confidential Software (including without
limitation any of the source code for the Owned


                                      46
<PAGE>
 
Software) has been advised of the confidential and proprietary nature of the
Trade Secrets and the Confidential Software and any such agent, consultant,
distributor or licensee has been required to enter into a written agreement
("Confidentiality Contract") with the appropriate Selling Entity acknowledging
and agreeing that (i) the Owned IP is and shall remain the sole and exclusive
property of, and may be confidential to, such Selling Entity, and (ii) the Owned
IP is not to be used or disclosed to any Person other than as specifically
authorized by such Selling Entity. Each of the Confidentiality Contracts and
Employee IP Contracts relating to the Transferred Intellectual Property
Interests was and is in full force and effect, and constitutes the legal, valid
and binding obligation of each Selling Entity which is a party thereto and, to
the best knowledge of the Selling Entities without independent investigation,
each other Person which is a party thereto, enforceable in accordance with its
terms, except that (iii) such enforcement may be subject to bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter in
effect relating to creditors' rights generally, and (iv) the remedy of specific
performance and injunctive relief may be subject to equitable defenses and to
the discretion of the court before which any proceeding may be brought. Each
Selling Entity has kept all of the Trade Secrets, including without limitation
all of the source code for the Owned Software, strictly confidential and secret.
The Trade Secrets are not and have not been a part of the public knowledge or
literature. No Selling Entity has disclosed, divulged or otherwise provided
access to any part of the source code for the Owned Software other than to
Persons which have entered into written Confidentiality Contracts with the
appropriate Selling Entity or who have a confidential relationship with the
Selling Entity or a duty to keep such source code for the Owned Software
confidential. To the best knowledge of the Selling Entities without independent
investigation, no Person which is a party to an IP Contract or confidentiality
agreement or has a confidential relationship with any Selling Entity is in
violation of, or in default under, any term or provision of such Contract which
relates to the Owned IP.

     (c)  All Know-How comprising a part of the Business is included in the
assets assigned to the Acquiring Entities by the Selling Entities in this
Agreement. Schedule 3.33(c) sets forth a true, complete and correct list of all
           ----------------                                                    
locations where the descriptions of any material Know-How comprising a part of
the Business is kept.  Such descriptions explain the material Know-How
comprising a part of the Business.  Each Selling Entity has taken all
commercially reasonable appropriate measures to protect in all material respects
the confidential and proprietary nature of the information related to the
business strategy, finances, marketing plans or employees of the Business which
has not been published and is not generally known to the public.

     3.34 Accuracy of Consent Schedules.  Schedules 2.5(d) and 7.4 set forth
          -----------------------------   ----------------     ---          
a true, complete and correct list of all material Consents from any Tribunal or
other Person as may be necessary or appropriate to consummate the transactions
contemplated by this Agreement in accordance with this Agreement and to enable
the Acquiring Entities to carry on and conduct the Business, in all material
respects, subsequent to the applicable Closing in substantially the same manner
as was carried on and conducted prior to such Closing, or that are necessary to
prevent a breach of or a default or penalty, or increase in payments, under or a
termination of any material Contract relating to the Business.

     3.35 Confidential Information.  All confidential or proprietary
          ------------------------                                    
information relating to any aspect of the Business which has been provided by
any Selling Entity to any Person that entered or proposed to enter into
negotiations for the sale of the Business (including a sale of capital stock of

                                      47
<PAGE>
 
any Selling Entity) or any portion thereof, whether or not under a Contract or
other assurances of confidentiality, has been destroyed or returned to the
applicable Selling Entity.

     3.36 Brokers.  None of the Selling Entities has authorized any Person to
          -------                                                              
act as a broker or finder or in any similar capacity in connection with this
Agreement or the transactions contemplated hereby in such a manner as to give
rise to a valid claim against EDS or any of the Acquiring Entities for any
brokers' or finders' fees or similar fees or expenses.

     3.37 Commercial Software.   The Software subject to each of the EMS
          -------------------                                             
License Agreement and the SolidEdge License Agreement are commercial computer
Software which is used regularly for other than government purposes and is sold,
licensed or leased in significant quantities to the general public at
established market or catalog prices.

Date in the form and detail similar to those included within the Financial
Statements, certified by the chief financial officer or treasurer (or other
comparable officer) of Intergraph as being prepared in accordance with GAAP and
fairly presenting the results of operations of the Business for the period then
ended, subject to normal, recurring quarter-end and year-end audit adjustments,
as described therein. Following the Principal Closing Date and prior to the
consummation of each International Closing, Intergraph will furnish to USI, as
soon as available, but in any event not later than 30 days after the end of each
calendar month, an unaudited balance sheet for each Selling Entity which has not
yet consummated its International Closing with respect to the Business as of the
end of such month and the related unaudited statements of revenues and direct
expenses of such Selling Entity with respect to the Business for such month in
the form and detail similar to those included within the Financial Statements,
certified by the chief financial officer or treasurer (or other comparable
officer) of Intergraph as being prepared in accordance with GAAP and fairly
presenting the financial position of the Business conducted by the Selling
Entity as of the dates thereof and the results of operations of the same for the
period then ended, subject to normal, recurring quarter-end and year-end audit
adjustments, as described therein. All such financial statements described above
shall be true, complete and correct and shall be prepared in accordance with
GAAP applied consistently throughout the periods reflected therein and with
prior periods (except as approved by such officer and disclosed therein). The
Selling Entities have been advised that USI intends to include the Financial
Statements (and possibly the unaudited financial statements for the Business for
periods following January 1, 1998) in a Registration Statement on Form S-1 to be
filed with the Securities and Exchange Commission and consent to the inclusion
thereof in such Registration Statement (and similar financial statements for
subsequent periods depending on the timing of the filing of such Registration
Statement). USI has been advised by the Securities and Exchange Commission that
it may include a statement of assets purchased in such Registration Statement in
lieu of the Balance Sheet, and Intergraph agrees to promptly furnish such
Statement to USI for inclusion in any such Registration Statement. Intergraph
will obtain the consent of Ernst & Young to the inclusion of their report on the
Financial Statements in any such Registration Statement and will instruct Ernst
& Young to cooperate with a reasonable request for a "comfort letter" which may
be requested by the underwriters.

     5.7   Non-Solicitation.  From the date hereof and until the five-year

anniversary of the Principal Closing Date, neither Intergraph nor any Affiliate
of Intergraph shall, directly or indirectly, solicit for employment (other than
through public advertisements or other widely disseminated employment notices)

who is then currently employed by any of the Acquiring Entities or any of their
Affiliates, and during such period, without the prior written consent of USI,
Intergraph may not offer employment or employ any person who identified on

Entities contemplated hereby.

will not incur or pay legal or consulting fees or expenses in connection with

           ------------------                                          
Acquiring Entity shall consider or be advised that any further assignments,

Property Interests to the applicable Acquiring Entities; provided, however, that
any such request shall be subject to any limitations or restrictions contained
in this Agreement.

           ---------------------                                         
Entities, during the period commencing on the date of this Agreement and ending
on the earliest to occur of (a) the final Closing or (b) termination of this
Agreement in accordance with Section 10.2, none of the Selling Entities shall
                             ------------                                    
provide, and each of the Selling Entities will cause its respective directors,
officers, employees and other representatives not to provide, any information
with respect to, or participate in any discussions concerning, any corporate
transaction relating to a sale or transfer (directly, indirectly or by operation
of law) of any or all of the Acquired Assets, any merger or corporate
reorganization relating to all or any of the Acquired Assets or any other
significant corporate transaction involving any of the Acquired Assets.

     5.12  Noncompetition.
           --------------   

     (a)   The Selling Entities agree that during the seven-year period
commencing on the date of this Agreement they (i) will not, either directly or
indirectly (including through any Affiliate), own, manage, control or operate or
participate in the ownership, management, operation or control of, any business,
whether in corporate proprietorship or partnership form or otherwise, which
engages in a Competitive Activity in any location, whether inside or outside of
the United States; (ii) will not engage in a Competitive Activity at any place,
whether inside or outside of the United States, directly or indirectly
(including through an Affiliate), whether individually, in partnership, jointly,
or in conjunction with, or on behalf of, any Person; and (iii) will not,
directly or indirectly (including through an Affiliate), whether individually,
in partnership, jointly, or in conjunction with, or on behalf of, any Person,
solicit or accept any business which requires engagement in


                                      55
<PAGE>
 
Competitive Activities; provided, however, the foregoing shall not be deemed to
prohibit the Selling Entities from the performance of its obligations under the
CAD II Contracts as contemplated by the SolidEdge License Agreement, the EMS
License Agreement and the SolidEdge Reseller Agreement.

     (b)   The term "Competitive Activity" means the maintenance, marketing or
selling, or the development for marketing or sale by a third party, of three-
dimensional modeling Software intended primarily for use in the automotive,
aerospace or manufacturing (including, without limitation, mechanical design of
consumer products, consumer electronics, computers and machine tooling)
industries for equipment design, machine design, product design, finite element
analysis, mechanism analysis or numerical control tool path creation, provided,
however, that the foregoing shall not be deemed to restrict Intergraph from the
maintenance, marketing, development or sale of Software intended to be used for
the Intergraph Fields or the Joint Fields.

     (c)   The parties hereto specifically acknowledge and agree that the remedy
at law for any breach of the foregoing will be inadequate and that the aggrieved
party, in addition to any other relief available to it, shall be entitled to
temporary and permanent injunctive relief without the necessity of proving
actual damage.  In the event that the provisions of this Section 5.12 should
ever be deemed to exceed limitations provided by applicable law, then the
parties hereto agree that such provisions shall be reformed to set forth the
maximum limitations permitted; provided, however, nothing in this Section 5.12
shall prevent a Selling Entity or any Affiliate thereof from acquiring less than
a 2% ownership interest in a company which is engaged in a Competitive Activity.
The provisions of this Section 5.12 shall not restrict Intergraph from engaging
in any activity not prohibited hereunder or by the exclusive nature of certain
of the Intellectual Property covered by the Transferred Intellectual Property
License Agreements.

Closing to each Transitioned Employee who was employed immediately prior to such
Closing by such Selling Entity.  Each of the Closing Agreements may set forth
additional obligations or procedures for effecting the foregoing obligations of

     (c)   Intergraph Stock Incentive Plan.  Intergraph shall extend, for a
           ------------------------------- 
period of three months from the date of termination with respect to each
Transitioned Employee, the exercise periods under the Intergraph Corporation
1992 Stock Option Plan and the Intergraph Corporation 1997 Stock Option Plan for
all vested awards as of the date of termination of employment by a Selling

     (d)   Intergraph 401(k) Plan.  Effective as of the date of the termination
           ----------------------      
of employment by a Selling Entity in connection with this Transaction,
Intergraph shall take all actions which are necessary and appropriate to fully
vest each Transitioned Employee in all amounts in such employee's individual
account in the Intergraph Corporation SavingsPlus Plan (the "Intergraph 401(k)
Plan"). Any Transitioned Employee who, as of the date of termination of such
employee's employment with a Selling Entity, has an outstanding balance on any
loan from the Intergraph 401(k) Plan, shall be eligible to transfer such loan,
along with all amounts vested in such employee's Intergraph 401(k) Plan
individual account, into the EDS Deferred Compensation Plan ("EDS 401(k) Plan")
pursuant to a trust-to-trust transfer ("Plan Asset Transfer") made in accordance
with the administrative policies and procedures of the Electronic Data Systems
Deferred Compensation Plan (the "EDS 401(k) Plan") and Section 414(l) of the
Code, provided that at the time of the Plan Asset Transfer Intergraph can
represent and warrant to EDS that the Intergraph 401(k) Plan (i) provides for
Plan Asset Transfers and (ii) is a qualified employee pension benefit plan in
compliance with Code Sections 401 et seq. The plan administrator of the
                                  -------
Intergraph 401(k) Plan shall, upon reasonable request, promptly provide the plan
administrator of the EDS 401(k) Plan with any and all data, records and other
information pertaining to any Transitioned Employee, a beneficiary, dependent,
spouse or former spouse of any Transitioned Employee, the Intergraph 401(k) Plan
individual account for any Transitioned Employee, and any other information
considered necessary and appropriate for the plan administrator of the EDS
401(k) Plan to establish and administer an individual account for any
Transitioned Employee in the EDS 401(k) Plan. The plan administrator of the
Intergraph 401(k) Plan shall further cooperate to take all such reasonable
actions as are necessary or appropriate for such plan administrator to take to
effect the Plan Assets Transfer in a timely and efficient manner, including the
filing of any reports, notices or disclosures which may be required by any
governmental agency.

     (e)   Foreign Nationals.  The Transitioned Employees identified on Schedule
           -----------------                                            --------
5.13(e) are foreign nationals working in the United States ("Foreign National
- -------                                                                      
Employees"). Each Foreign National Employee shall remain employed by Intergraph
until such persons are granted permanent United States residency by the
Department of Immigration (the "Transition Date").  During the period from the
applicable Closing Date through the applicable Transition Date, each Foreign
National Employee shall be employed by Intergraph for the full-time benefit of
USI and the Acquired Business, and USI shall reimburse Intergraph for their
salaries at the rates set forth opposite their respective names on Schedule
                                                                   --------
5.13(e), which rates are the current salaries of such persons, and for the
- -------                                                                   
direct benefit costs of Intergraph attributable to such persons.  During this
period, USI may request that the employment of any such person be terminated.
In such event, later than five days following the date of such request
Intergraph may either (i) continue the employment of such person for
Intergraph's benefit, in which event USI shall discontinue payments of salary
reimbursement, or (ii) terminate the employment of such person, in which event
USI will 

                                      57
<PAGE>
 
reimburse Intergraph for any required severance payments to any terminated
Foreign National Employee in accordance with Intergraph's severance policy.

     (f)   Employment Assistance.  Each Selling Entity will cooperate with the
           ---------------------                                              
applicable Acquiring Entity in (i) where the law so requires, the facilitation
of the transfer of the employees of the Selling Entity engaged in the Business
to the relevant Acquiring Entity, (ii) the performance by such Acquiring Entity
of its obligations under Section 6.3 to offer employment with USI or another
                         -----------                                        
Acquiring Entity to such employees of the Business as such parties shall agree
upon prior thereto or in the applicable Closing Agreement and (iii) such
Acquiring Entity's effort to employ such employees.  No Selling Entity will (A)
except with the written consent of USI, make any representations, promises or
other communications, whether written or oral, to such employees regarding
employment with any of the Acquiring Entities or employee benefits, plans or
practice of the Acquiring Entities, or (B) take any act that diminishes any
Acquiring Entity's right to dismiss, subject to applicable law, any such
employee with or without cause.

     (g)   Expense Report Reimbursement.  Each Selling Entity will reimburse a
           ----------------------------                                       
Transitioned Employee for any business related expenses incurred by that
Transitioned Employee with respect to a period prior to the Principal Closing in
accordance with the Selling Entities' standard expense reimbursement policy.

     (h)   Transfer of Certain Non-U.S. Pension Assets.
           ------------------------------------------- 

           (I)   At or prior to the applicable International Closing, Intergraph
     shall contribute in cash to the underlying trusts (or comparable funding
     arrangements) of the EDS pension plans (the "EDS Pension Trusts") or in the
     case of an unfunded book reserve maintained by Intergraph or an Affiliate
     of Intergraph, to USI (which shall accept such funds on behalf of EDS) an
     amount equal to the Projected Benefit Obligation value ("PBO") of the
     benefits accrued for and in respect of the Transitioned Employees under the
     applicable Intergraph pension plan as determined under the rules of the
     respective Intergraph pension plan and applicable law as if the
     Transitioned Employee's employment with a Selling Entity had terminated the
     day before the applicable Closing Date. The PBO will be calculated using
     the Intergraph pension plan rules as in effect on the applicable Closing
     Date and the actuarial methodology and assumptions which were applicable
     for the EDS annual disclosure under FAS87 as of December 31, 1997. For this
     purpose, each Transitioned Employee shall be deemed to have a fully vested
     benefit under the applicable Intergraph pension plan. Notwithstanding the
     foregoing, to the extent that the applicable Intergraph pension plan is a
     defined contribution plan, the PBO shall refer to each Transitioned
     Employee's full account balance credited to him or her under the Intergraph
     pension plan, consisting of both employee and employer contributions and
     any adjustments thereon due to investment performance, as of the applicable
     Closing Date.


           (II)  To the extent permitted by law, all payments will be made
     directly from the underlying trust (or other comparable funding
     arrangements) of each Intergraph pension plan (the "Intergraph Pension
     Trusts") to the corresponding EDS Pension Trust in the respective country
     and, to the extent so paid, Intergraph's obligation to pay the 

                                      58
<PAGE>
 
     amounts referred to in (I) above shall be correspondingly reduced. If,
     under applicable law the legally required minimum amount to be transferred
     exceeds the PBO, then such payment will in no event be less than the amount
     necessary to satisfy the requirements of any applicable law.


                                      59
<PAGE>
 
           (III) Intergraph shall pay interest on the amount payable to the EDS
     Pension Trust or USI, as the case may be, accruing for the period beginning
     on the day after the Principal Closing Date until the date the amount is
     paid to the EDS Pension Trust at the discount rate per annum used to
     calculate the PBO. To the extent permitted by law, this payment shall be
     made from the Intergraph Pension Trusts to the EDS Pension Trusts.


           (IV)  For each Transitioned Employee, Intergraph will transfer from
     the Intergraph Pension Trusts, and USI will assume (or cause the applicable
     EDS pension plan to assume) as of the EDS plan eligibility date, an amount
     of plan liabilities equal to the PBO under the Intergraph pension plan as
     of the applicable Closing Date.

           (V)   All calculations contemplated herein shall be performed by an
     actuary designated by USI, which may be reviewed by an actuary designated
     by Intergraph prior to the transfer, and shall be performed within 30 days
     after the applicable Closing Date, or as soon thereafter as practicable
     (provided that to the extent permitted by law all payments to be made at
     the applicable Closing shall be estimated in good faith by USI and
     Intergraph with such estimates to be confirmed on a post-closing basis by
     such actuary or actuaries). EDS shall cause the EDS Pension Trusts to
     accept their respective transfer of plan assets and the corresponding EDS
     Pension Plans to assume their respective transfer of liabilities (such
     transfers of plan assets and liabilities and the acceptance of such assets
     and assumption of such liabilities shall hereafter be referred to as the
     "Transfers"). The Transfers will be accomplished in full compliance with
     applicable law. Further, Intergraph and USI will file or cause to be filed
     in a timely manner whatever reports, forms and notices as are necessary
     under applicable law as a result of the Transfers. EDS and Intergraph agree
     to cooperate with each other in providing the other on a timely basis with
     employee data and other information which may be reasonably required to
     effect the respective Transfers. Each Transfer will be accomplished by way
     of a single transfer of plan assets and liabilities from the respective
     Intergraph Pension Plan and will not occur until the PBO under the
     respective Intergraph Pension Plan has been determined.

     5.14  Intergraph Guaranty.  Intergraph hereby guarantees to the Acquiring
           -------------------  
Entities the due and punctual performance by each of the other Selling Entities
of its respective obligations under this Agreement and each of the Closing
Agreements.

     5.15  Enforcement of Confidentiality Agreement.  The Selling Entities
           ----------------------------------------  
agree to enforce, for the benefit of the Acquiring Entities any and all rights
of the Selling Entities under any Contract retained by the Selling Entities
pursuant to which any confidential or proprietary information relating to any
aspect of the Business was provided by any Selling Entity to any Person. The
Selling Entities shall promptly inform the Acquiring Entities of any breach of
which they become aware by any Person of the confidentiality obligations under
any such Contract relating to confidential or proprietary information relating
to the Business.

     5.16  Confidential Information.  Each of the Selling Entities hereby
           ------------------------                                        
acknowledges that the Acquiring Entities would be irreparably damaged if any
proprietary or confidential information 

                                      60
<PAGE>
 
possessed by any of the Selling Entities concerning the Business, the Acquired
Assets or any of the Acquiring Entities (except for any information that is or
becomes generally known to the public, otherwise than through a breach of this
Agreement) were disclosed to or used by any Person engaged in competition with
the Business or any of the Acquiring Entities. Each of the Selling Entities
agrees that it will not, and will not permit any of its Affiliates, directors,
officers, employees, accountants, agents and other representatives to use or
disclose any such confidential or proprietary information, except as expressly
permitted hereunder or under any other agreement between such Selling Entity and
USI or any of its Affiliates. If any Selling Entity is requested or required by
any Tribunal to disclose any of such proprietary or confidential information,
then such Selling Entity will provide USI with prompt written notice of such
request or requirement unless prohibited by applicable law. USI may then either
seek appropriate protective relief from all or part of such request or
requirement or waive such Selling Entity's compliance with the provisions of
this Section 5.16 with respect to all or part of such request or requirement.
     ------------                    
Such Selling Entity will cooperate with USI in attempting to obtain any
reasonable protective relief that USI chooses to seek. If, after USI has had a
reasonable opportunity to seek such relief, USI fails to obtain such relief,
then such Selling Entity may disclose only that portion of such proprietary or
confidential information which its legal counsel advises it is compelled to
disclose.

     5.17  Assistance and Cooperation.  After each respective Closing Date, each
           -------------------------- 
applicable Selling Entity agrees:

     (a)   to assist the applicable Acquiring Entities in preparing any tax
     returns that such Acquiring Entities are responsible for preparing and
     filing after such Closing Date with respect to that portion of the Business
     and the Acquired Assets conveyed on such Closing Date to the extent such
     tax returns require information not included within such Acquired Assets;
     to reasonably cooperate at the Acquiring Entity's cost in preparing for any
     audits of, or disputes with Tribunals regarding, any tax returns relating
     to such portion of the Business and the Acquired Assets; and to make
     available to the applicable Acquiring Entities and to any Tribunal as
     reasonably requested all information, records and documents relating to
     liabilities for taxes associated with such portion of the Business or the
     Acquired Assets;

     (b)   to provide the Acquiring Entities with reasonable access to the
     portions of the Selling Entities' tax records and reports, general ledgers
     and any other books, records, files or correspondence which relate to the
     Business and to preserve all such information, records and documents until
     the expiration of any applicable statutes of limitation or extensions
     thereof and as otherwise required by law; and

     (c)   to provide timely notice to the applicable Acquiring Entities in
     writing of any pending or threatened tax audits or assessments related to
     the Business or the Acquired Assets for periods beginning after such
     Closing Date and of which such Selling Entity has knowledge and to furnish
     such Acquiring Entities with copies of all correspondence received from any
     Tribunal in connection with any tax audit or information request with
     respect to any such period.

     5.18  Product Serial Numbers.  At or prior to the Principal Closing,
           ----------------------                                          
Intergraph shall furnish to USI a block of not less than 100,000 serial numbers,
assigned in accordance with 

                                      61
<PAGE>
 
Intergraph's Gen Key internal system, which the Acquiring Entities may assign
following such Closing to the products of the Business. The Selling Entities

                      COVENANTS OF THE ACQUIRING ENTITIES

     6.1   Consummation of Transactions.  Subject to the terms and conditions
           ----------------------------                                        
herein provided, from the date hereof through its applicable Closing Date, each
Acquiring Entity will use its best efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all things necessary, proper or
advisable to consummate and make effective, as promptly as practicable, the
transactions contemplated by this Agreement in accordance with the terms of this
Agreement applicable to such Acquiring Entity.  From the date hereof through its
applicable Closing Date, each Acquiring Entity shall not voluntarily take any
action or course of action inconsistent with the satisfaction of the respective
conditions, terms and provisions of this Agreement or the consummation of the
respective transactions contemplated by this Agreement in accordance with the
terms of this Agreement applicable to such Acquiring Entity.

     6.2   Notification of Certain Matters.  Prior to its applicable Closing
           ------------------------------- 
Date, each Acquiring Entity shall give prompt notice to Intergraph of any
material failure of any of the Acquiring Entities or any officer, director,
employee or agent thereof, to comply with or satisfy any covenant, condition or
agreement then remaining to be complied with or satisfied by it hereunder.

     6.3   Employment.  Effective upon the Principal Closing, USI will offer
           ----------                                                           
employment with USI or such Acquiring Entity to those employees of the Business
in the U.S. identified on Schedule 6.3 at the salaries set forth opposite their
                          ------------                                         
name on such Schedule, which salaries were the rates in effect on December 31,
1997 (except for any increases approved by the President of USI). Such offer
shall be consistent with the hiring policies of USI and, with respect to
Transitioned Employees in the United States, shall include employee benefits
generally comparable to those of other United States USI employees.  USI
reserves the right to revoke the offer and refuse to hire any employee who does
not satisfy USI's pre-employment requirements.  Effective upon each
International Closing, USI or another Acquiring Entity will make a similar offer
to those employees of the Business outside of the U.S. identified on Schedule
                                                                     --------
6.3.  USI shall recognize the service with Intergraph of each United States
- ---                                                                        
Transitioned Employee for purposes of its vacation policy. Nothing in this
Agreement shall diminish the right of USI or such other Acquiring Entity,
subject to any then applicable Legislative Enactments, to dismiss any of those
employees of the Selling Entities who become employees of USI or such other
Acquiring Entity with or without cause and to change the terms and conditions of
employment of any or all of such employees.

     6.4   Assistance with Specified Contracts and Litigation Contracts.  As
           ------------------------------------------------------------       
referenced in the proviso to the definition of Assumed Contracts in Section 1.1,
                                                                    ----------- 
no Specified Contract or Litigation Contract shall be considered to be an
Assumed Contract under or by reason of this Agreement.  With respect to any
Specified Contract or Litigation Contract to which a Selling Entity is a party,
the performance of the applicable Selling Entity's obligations thereunder shall
be deemed to be subcontracted or sublicensed to the applicable Acquiring Entity
for the remainder of the term of the 

                                      62
<PAGE>
 
Specified Contract or Litigation Contract, as the case may be, unless (a) in the
case of a Specified Contract, such Acquiring Entity reasonably determines that
such a subcontracting or sublicensing arrangement effectively subjects such
Acquiring Entity or any of its Affiliates or any employees of such Acquiring
Entity or any of its Affiliates to a Non-Compete Covenant, (b) in the case of a
Litigation Contract, such Acquiring Entity reasonably determines that such a
subcontracting or sublicensing arrangement effectively subjects such Acquiring
Entity or any of its Affiliates or any employees of such Acquiring Entity or any
of its Affiliates to any pending suit, action, litigation or proceeding or (c)
in either such case, such a subcontracting or sublicensing arrangement is not
permitted by such Specified Contract or Litigation Contract, as the case may be.
In any such case, the applicable Acquiring Entity, at the expense of the
applicable Selling Entity, will use commercially reasonable efforts to otherwise
assist the Selling Entity that is party thereto in the performance of such
Selling Entity's contractual obligations thereunder; provided, however, that the
                                                     --------  -------          
parties expressly acknowledge and agree that in no event shall such Acquiring
Entity be deemed to accept any obligation that could subject such Acquiring
Entity, any of its Affiliates or any employees of such Acquiring Entity or any
of its Affiliates to a Non-Compete Covenant or to any pending suit, action,
litigation or proceeding.  The Selling Entities shall cause the benefits of each
Specified Contract and Litigation Contract (or the economic equivalent thereof)
to be provided to the applicable Acquiring Entity and shall cooperate in any
arrangement required to provide such Acquiring Entity with the same, including
without limitation (i) maintenance by the Selling Entity of the Specified
Contract or Litigation Contract, as the case may be, in its name in trust for
the benefit of the Acquiring Entity or (ii) at the option of the Acquiring
Entity and at its cost, enforcement for the benefit of such Acquiring Entity of
such Specified Contract or Litigation Contract, as the case may be against a
third party.

     6.5   Trade Names and Service Marks.  Each Acquiring Entity agrees that it
           -----------------------------        
will discontinue the use, directly or indirectly, in any manner or form, of the
name "Intergraph" and the corresponding logo thereof; provided, however, that
until the earlier of (i) the six-month anniversary of the Principal Closing Date
and (ii) the date on which all inventory and supplies of the Business
transferred at a Closing shall be depleted, the Acquiring Entities shall be
permitted to use such name and logo only in connection with the distribution of
such inventory and supplies; and provided further that at any time following the
Principal Closing Date, the Acquiring Entities shall be able to identify that
the Business was previously owned by the Selling Entities.

     6.6   EDS and USI Guaranty.  EDS hereby guarantees to the Selling Entities
           -------------------- 
the due and punctual performance by each of the Acquiring Entities of its
respective obligations under this Agreement and each of the Closing Agreements,
provided, however, that the obligations of EDS under this Section 6.6 shall
terminate immediately following the Principal Closing. USI hereby guarantees to
the Selling Entities the due and punctual performance by each of the other
Acquiring Entities of its respective obligations under this Agreement and each
of the Closing Agreements.

     6.7   Assistance and Cooperation.  After the Principal Closing Date, the
           -------------------------- 
Acquiring Entities shall, to the extent reasonably requested by the Selling
Entities, make available to the Selling Entities and to any Tribunal all
information, records and documents relating to (i) liabilities of the Selling
Entities for Taxes relating to the Business, (ii) matters disclosed on Schedule
                                                                       --------
3.14, (iii) such other matters as the Selling Entities may reasonably request
- ----
relating to the Retained Assets or the performance of the Retained Liabilities.
Without limiting the 

                                      63
<PAGE>
 
generality of the foregoing, upon the request of the Selling Entities, the
Acquiring Entities shall use commercially reasonable efforts to permit certain
of the Transitioned Employees identified by the Selling Entities to appear as
witnesses or trial representatives, and to assist the Selling Entities in trial
preparation, in connection with any litigation or proceeding relating to the
matters disclosed on Schedule 3.14; provided, however, that the Selling Entities
                     -------------  --------  ------- 
shall bear all reasonable out-of-pocket expenses (but without other expense or
hourly charges) incurred by such Transitioned Employees in providing any such
requested assistance to the Selling Entities.

     indemnify a USI Indemnitee pursuant to Section 9.2(b) hereof to the extent
     that the Losses which resulted in such indemnification obligations arose
     due to the failure by USI to use any modification, enhancement or

     enhancement or adaptation, and that Intergraph could demonstrate to USI
     that such modification, enhancement or adaptation provided the same
     functionality as the BAG Tool, INGR Tool or SolidEdge Common Code that

of any of the Acquiring Entities contained in any certificate, document,
affidavit or instrument delivered pursuant to this Agreement (including without
limitation the Closing Agreements) (the "Intergraph Losses"), the foregoing
indemnity and hold harmless obligations of the Acquiring Entities relating to
such Intergraph Losses shall become operative and effective only if and when all
Intergraph Losses for which Intergraph Indemnitees are entitled to receive
indemnification under this Section 9.1 exceed, in the aggregate, $150,000 (it
                           -----------

expressly acknowledge and agree that the immediately preceding sentence shall
not apply to any Losses other than the Intergraph Losses.  The parties further
agree that the liability of the Acquiring Entities specified above with respect
to the Intergraph Losses shall be reduced to the extent of any insurance
proceeds actually received by any of the Intergraph Indemnitees for such
Intergraph Losses from any of the Acquiring Entities or any of their Affiliates

     Law relating to the Compliance Group or a Compliance Property (whether or
     not such liability or obligation would constitute a breach of the

     Lease Agreement as a result of actions taken by USI following the Principal
     Closing Date;

     (m)   any liability or obligation arising out of the failure of the

Notwithstanding the foregoing provisions of this Section 9.2, with respect to
                                                 -----------

of any of the Selling Entities contained in any certificate, document, affidavit
or instrument delivered pursuant to this Agreement (including without limitation
the Closing Agreements) (the "USI Losses"), the foregoing indemnity and hold
harmless obligations of the Selling Entities relating to such USI Losses shall
become operative and effective only if and when all USI Losses for which USI
Indemnitees are entitled to receive indemnification under this Section 9.2
                                                               -----------
exceed, in the aggregate, $150,000 (it being understood and agreed that all such
USI Losses shall accumulate until such time as they exceed $150,000, at which
time the Selling Entities shall be obligated to indemnify any USI Indemnitees
seeking indemnification under this Section 9.2 
                                   -----------

for the aggregate amount of the USI Losses, rather than the amount that exceeds
$150,000). The parties expressly acknowledge and agree that the immediately
preceding sentence shall not apply to any Losses other than the USI Losses. The
parties further agree that the liability of the Selling Entities specified above
with respect to the USI Losses shall be reduced to the extent of any insurance
proceeds actually received by any of the USI Indemnitees for such USI Losses
from any of the Selling Entities or any of their Affiliates or any insurance
carrier of the Selling Entities or any of their affiliates.

     9.3   Satisfaction of Claims.  If any Person entitled to indemnification
           ----------------------                                              
under this Article IX (an "Indemnified Party") desires to assert any claim for
           ----------                                                         
indemnification or to be held harmless under this Article IX (a "Claim"), the

Indemnified Party shall deliver to the Person that is obligated to provide such
indemnification (the "Indemnifying Party") notice of its demand for satisfaction
of such Claim (a "Request"), specifying in reasonable detail the amount of such
Claim and, to the extent practicable under the circumstances, the basis for
asserting such Claim. Within 30 days after the Indemnifying Party has been given
a Request, the Indemnifying Party shall either (i) satisfy the Claim requested
to be satisfied in such Request by delivering to the Indemnified Party payment
by wire transfer or a certified or bank cashier's check payable to the
Indemnified Party in immediately available Federal Reserve Funds in an amount
equal to the amount of such Claim, or (ii) notify the Indemnified Party that the
Indemnifying Party contests such Claim by (A) delivering to the Indemnified
Party an objection to such Claim, specifying in reasonable detail, to the extent
practicable under the circumstances, the basis for contesting such Claim, and
(B) demanding arbitration of the Claim in accordance with Section 10.11.  If the
                                                          -------------         
Indemnifying Party fails to satisfy a Claim (or portion of a Claim) within 30
days after the Indemnifying Party has been given a Request with respect to such
Claim, and whether or not the Indemnifying Party has contested such Claim, the
Indemnifying Party shall pay the Indemnified Party asserting such Claim interest
on the unpaid amount of such Claim (or unpaid portion of a Claim) at the Prime
Rate, computed from the date such Request was given to the Indemnifying Party to
the date such Claim (or portion of a Claim) is satisfied; provided, however,
                                                          ------------------
that the Indemnifying Party shall not be required to pay the Indemnified Party
- ----                                                                          
interest on that part of any unpaid Claim (or portion of a Claim) which the
Indemnifying Party successfully contests.

     9.4   Matters Which May Give Rise to Claims.
           -------------------------------------   

     (a)   Notice and Control.  Within 20 days (or such earlier time as might be
           ------------------                                                   
required to avoid prejudicing the Indemnifying Party's capacity to defend) after
receipt by an Indemnified Party of notice of commencement of any action
evidenced by service of process or other legal pleading which it determines has
given or could give rise to a Claim (a "Third-Party Matter"), the Indemnified
Party shall give the Indemnifying Party written notice thereof (together with a
copy of such Claim, process or other legal pleading). The Indemnifying Party
shall assume the defense of such Claim and in connection therewith:

           (i)   such Indemnifying Party shall defend such Third-Party Matter at
           its own expense, in good faith and in a manner consistent with the
           best interests of the Indemnified Party;

                                      71
<PAGE>
 
           (ii)  such Indemnifying Party shall keep the Indemnified Party fully
           informed as to the status of the defense of such Third-Party Matter;

           (iii) such Indemnifying Party shall employ legal counsel, accountants
           and/or other experts reasonably satisfactory to the Indemnified Party
           to represent the Indemnified Party in connection with such Third-
           Party Matter;

           (iv)  the Indemnified Party shall have the right to observe and be
           present (at its own expense) at any and all meetings, conferences and
           other proceedings with respect to such Matter;

           (v)   the Indemnifying Party shall obtain the prior written approval
           of the Indemnified Party before entering into any settlement of such
           Third-Party Matter or ceasing to defend against such Third-Party
           Matter, if, pursuant to or as a result of such settlement or
           cessation, injunctive or other equitable relief would be imposed
           against the Indemnified Party;

           (vi)  without the written consent of the Indemnified Party, the
           Indemnifying Party shall not consent to the entry of any judgment or
           enter into any settlement that does not include as an unconditional
           term thereof the giving of a release from liability in respect of
           such Third-Party Matter to each Indemnified Party by the claimant or
           plaintiff; and

           (vii) unless such Indemnifying Party is successful in defending such
           Third-Party Matter on the merits, any and all losses, damages, costs,
           and expenses which any Indemnified Party shall suffer or incur in
           connection with such Third-Party Matter shall be conclusively deemed
           to be losses, damages, costs and expenses as to which the Indemnified
           Party shall have the right to be indemnified and held harmless under
           this Article IX.
                ---------- 

     Neither the observation or participation by any Indemnified Party in the
defense of any Third-Party Matter, nor the failure by any Indemnified Party to
observe or participate in the defense of any Third-Party Matter, shall affect in
any way the liabilities and obligations of the Indemnifying Party with respect
to such Third-Party Matter under this Article IX.
                                      ---------- 

     If the Indemnifying Party does not assume the defense of such Third-Party
Matter with legal counsel reasonably satisfactory to the Indemnified Party
within 15 days after the Indemnifying Party has received notice of such Third-
Party Matter from the Indemnified Party, the Indemnified Party shall have the
right to undertake the defense, compromise and settlement of such Third-Party
Matter on behalf of and for the account and risk of the Indemnifying Party.

     (b)   Expenses. If the Indemnified Party undertakes the defense, compromise
           --------    
and settlement of such Third-Party Matter pursuant to Section 9.4(a), the
                                                       --------------     
Indemnifying Party will promptly reimburse the Indemnified Party for all
reasonable fees, costs and expenses (including without limitation any Legal
Expenses) incurred by the Indemnified Party in respect of such Third-Party
Matter. The reimbursement of such fees, costs and expenses shall be made by
periodic 

                                      72
<PAGE>
 
payments during the course of any investigation or defense, as and when bills
are received or expenses incurred.

     (c)   Cooperation.  The Indemnified Party and the Indemnifying Party shall
           -----------                                                         
cooperate in the defense of a Third Party Matter that is defended in accordance
with this Section 9.4, and shall make available to the defending person or its

successors and assigns, except for the liability of any party for any breach of
this Agreement, provided that the right to terminate this Agreement pursuant to
this sentence shall not be available to any party whose failure to perform any
material covenant or obligation under this Agreement has been the cause of or

amended except by a written instrument executed by or on behalf of each of the
parties to this Agreement. The observance of any term of this Agreement may be

Agreement, no delay or omission on the part of any party in exercising any right

any waiver on the part of any party of any right or privilege under this
Agreement operate as a waiver of any other right or privilege under this
Agreement nor shall any single or partial exercise of any right or privilege
preclude any other or further exercise thereof or the exercise of any other
right or privilege under this Agreement.

     10.9  Governing Law.  Notwithstanding the place where this Agreement may be
           ------------- 
executed by any of the parties hereto, the parties expressly agree that all the

Selling Entities hereby irrevocably, for itself and on behalf of its Affiliates,
(a) submits to the non-exclusive jurisdiction of the courts of the United States
of America for the Eastern District of Missouri (such courts being herein
referred to as the "Agreed Courts") solely in respect of the interpretation and
enforcement of the provisions of this Agreement and of the documents referred to
herein, and (b) waives and agrees not to assert, as a defense in any Proceeding
for the interpretation or enforcement hereof or of any document referred to
herein, that it is not subject to the jurisdiction of the Agreed Courts, or that
such Proceeding may not be brought or is not maintainable in the Agreed Courts,
or that this Agreement or any of such documents may not be enforced in or by the
Agreed Courts, or that its property is exempt or immune from execution, or that
the Proceeding is brought in any inconvenient forum or that the venue of the
Proceeding is improper.  Such submission to jurisdiction shall not affect any
right of any Acquiring Entity or any Selling Entity to commence Proceedings in
any other jurisdiction, and the commencement of Proceedings in any jurisdiction
shall not preclude any Acquiring Entity or any Selling Entity from commencing
Proceedings in any other jurisdiction.  Service of any and all process that may
be served on any party hereto in any Proceeding arising out of this Agreement
may be made in the manner and to the addresses set forth in Section 10.6 and

service thus made shall be taken and held to be valid personal service upon such
party by any party hereto on whose behalf such service is made.  Nothing shall

     10.11 Arbitration.
           ----------- 

                                      76
<PAGE>
 
     (a)  In the event of any dispute, controversy or claim of any kind or
     nature arising under or in connection with this Agreement or the other
     agreements contemplated hereby that the parties are unable to resolve
     through informal discussions or negotiations, the parties agree to submit
     such dispute, controversy or claim to arbitration in accordance with the
     following procedures:

          (i)   Either Intergraph or USI may demand arbitration by giving the
          other party written notice to such effect, which notice will (i)
          describe, in reasonable detail, the nature of the dispute, controversy
          or claim, the amount, if any, involved and the remedy sought, and (ii)
          name an independent arbitrator who is experienced in the resolution of
          disputes, controversies or claims of such a nature. In addition, such
          party demanding arbitration shall take such steps as are necessary to
          commence arbitration proceedings under the rules of the American
          Arbitration Association (including, without limitation, the payment of
          any administrative fees provided thereunder).

          (ii)  Within 30 days after the other party's receipt of such demand,
          such other party will name a second independent arbitrator who is
          experienced in the resolution of disputes, controversies or claims of
          such a nature.

          (iii) The two arbitrators so named will promptly select a third
          neutral arbitrator who is experienced in the resolution of disputes,
          controversies and claims of such a nature. The arbitration will be
          heard by a panel of the three arbitrators so chosen (the "Arbitration
          Panel") in the United States, and the resolution of the dispute,
          controversy or claim will be determined by a majority vote of the
          Arbitration Panel. The Commercial Arbitration Rules of the American
          Arbitration Association will govern the conduct of the arbitration and
          the selection of the arbitrators. The arbitration proceedings shall be
          conducted in the English language.

          (iv)   The Arbitration Panel may apportion between the parties as the
          Arbitration Panel may deem equitable the fees, costs and expenses of
          the arbitration incurred by the parties.  The Arbitration Panel may
          also award interest on any awards made by the Arbitration Panel.  In
          the assessment of any award of interest, the Arbitration Panel shall
          consider any delay in the satisfaction of Claims by the Indemnifying
          Party.

          (v)    The party demanding arbitration will request the Arbitration
          Panel to (i) allow for the parties to request reasonable discovery
          pursuant to the rules then in effect under the Federal Rules of Civil
          Procedure for a period not to exceed 60 days prior to such arbitration
          (all with the stated intent of establishing a fair, speedy and cost-
          effective dispute resolution mechanism) and (ii) require the testimony
          to be transcribed. No findings of fact or opinions of law will be
          required to be made by the arbitrators.

                                      77
<PAGE>
 
           (vi)   Any award rendered by the Arbitration Panel will be final,
           conclusive and binding upon the parties and any judgment thereon may
           be entered and enforced in any court of competent jurisdiction.

     (b)   Other than actions for temporary and permanent injunctive relief or
     specific performance or any action necessary to enforce the award of the
     Arbitration Panel, the provisions of this Section 10.11 will constitute the
                                               -------------                    
     exclusive remedy of the parties and a complete defense to any suit, action
     or other proceeding instituted in any court or before any administrative
     tribunal with respect to any dispute, controversy or claim arising under or
     in connection with this Agreement or the other agreements contemplated
     hereby. Nothing in this Section 10.11 will prevent the parties from
                             -------------                              
     exercising their rights to terminate this Agreement in accordance with
                                                                           
     Section 10.2.
     ------------ 

     (c)   Notwithstanding any other provision in this Section 10.11 to the
                                                      ------------- 
     contrary, the Arbitration Panel will not have the authority to amend the
     provisions of this Section 10.11 without obtaining the prior written
                        -------------
     consent of each of the parties to this Agreement.

     10.12 Specific Performance.  In addition to any other remedy to which any
           --------------------
party may be entitled, including arbitration as provided in Section 10.11, the
                                                            -------------     
parties agree that temporary and permanent injunctive relief and specific
performance (which specific performance may take the form of delivery of any
assets which may inadvertently have been omitted from a Schedule hereto) may be
granted, to the extent permitted under applicable law, without proof of actual
damages or inadequacy of legal remedy in any proceeding that may be brought to
enforce any of the provisions of this Agreement; provided, however, that this
                                                 --------  -------           
Section 10.12 shall not be deemed to abrogate the agreement of the parties
- -------------                                                             
provided in Section 10.11(b).

     10.13 Tax Matters
           -----------

     (a)   Tax Reporting for 1998.  The Selling Entities will (i) prepare and
           ----------------------                                            
     timely file with each applicable tax or revenue service, taxing authority,
     or taxing tribunal (where the operations of the Business are subject to
     Tax) Tax Returns which include all income, gains, losses, deductions and
     credits attributable to the operations of the Business for the period or
     periods up to but not including the applicable Closing Date and (ii) make
     timely payments of, and indemnify and hold the Acquiring Entities harmless
     from and against, all Taxes required to be reflected on such Tax Returns.
     The Acquiring Entities will (A) prepare and timely file with each
     applicable tax or revenue service, taxing authority, or taxing tribunal
     (where the operations of the Businesses are subject to Tax) Tax Returns
     which include all income, gains, losses, deductions and credits
     attributable to the operations of the Business for the period on or after
     the applicable Closing Date and (B) make timely payments of, and indemnify
     and hold the Selling Entities harmless from and against, all Taxes required
     to be reflected on such Tax Returns.

     (b)   Transaction Taxes.
           ----------------- 

           (i) Liability, Indemnification and Payment. (A) Intergraph (Italia)
               --------------------------------------                         
           L.L.C. and Unigraphics Solutions S.p.A. agree to equally share and 
           pay the 3% Italian
                                      78
<PAGE>
 
          registration tax and the cost of the third party appraisal. (B) If,
          contrary to the considered judgment of the parties' as set forth in
          Section 10.13(b)(ii) below, any sales and use taxes are imposed by any
          taxing authority, tax or revenue service, or tax tribunal within the
          state of Alabama (the "Alabama Sales and Use Taxes"), the party upon
          which such Alabama Sales and Use Taxes are legally imposed shall pay
          such sales and use taxes and any related interest, penalty, etc. to
          the applicable taxing authority and the other party shall promptly pay
          to, indemnify and hold the paying party harmless from and against 50%
          of such Alabama Sales and Use Taxes and any related interest, penalty,
          etc. (C) The Acquiring Entities shall pay, and indemnify and hold the
          Selling Entities harmless from and against, all other Transaction
          Taxes ("Other Transaction Taxes"). (D) In every case where a payment
          of Transaction Taxes is required to be made directly by the indemnitee
          to the relevant taxing authority, (i) the indemnifying party shall pay
          to the indemnitee the amount of such Transaction Taxes which are
          required to be paid by the indemnitee within thirty (30) days of the
          date that the indemnitee furnishes the indemnifying party with written
          notice and documentation proving that such Transaction Taxes are due
          and payable by the indemnitee to the applicable taxing authority and
          (ii) such amount shall bear interest at 18% per annum if not paid
          within such thirty (30) day period. In this regard, Transaction Taxes
          shall not be deemed to be due and payable by the indemnitee during any
          period in which such Transaction Taxes may legally be contested
          without advance payment, unless the indemnifying party requests the
          indemnitee to make payment of such Transaction Taxes.

          (ii) Planning and Cooperation. Each of the Selling Entities and each
               ------------------------                                       
          of the Acquiring Entities (A) believe, based on their separate and
          independent research, that each of the transfers provided for in this
          Agreement are transfers of a business as a going concern, if and to
          the extent allowable under applicable Legislative Enactments with
          respect to value added taxes ("VAT") (if this belief proves to be in
          error, the Selling Entities shall invoice the Acquiring Entities for
          any such VAT.), (B) believe, based on their separate and independent
          research, that each of the transfers provided for in this Agreement
          qualify as transfers that are exempt from Alabama Sales and Use Taxes,
          based on the casual sale and other allowable exemptions, and (C) shall
          act in a manner consistent with the foregoing.  In the event that
          there is any assertion or determination that VAT, Alabama Sales and
          Use Tax, or Other Transaction Tax applies or may apply in connection
          with any transactions under this Agreement, or in connection with any
          transactions under this Agreement as to which any type of Other
          Transaction Tax does or may apply, the applicable Selling Entities and
          the applicable Acquiring Entities shall, in consultation and
          cooperation with each other and on a timely basis and commercially
          reasonable basis, give such notices, make such filings and requests,
          adopt such reporting positions, provide such information, and appear
          before such tax or revenue service, taxing authority, or taxing
          tribunal as are required, desirable, or reasonably requested by the
          other party, in an effort to maintain that such transfers are exempt
          or otherwise outside the scope of VAT, the Alabama Sales and Use Tax,
          or Other Transaction Taxes (as the case may be), in order to 

                                      79
<PAGE>
 
          obtain or perfect an exemption of such transactions from VAT, the
          Alabama Sales and Use Tax, or Other Transaction Taxes (as the case may
          be), in order to obtain a reduction in rates for VAT applicable to
          such transactions, or in order to obtain a recovery of any VAT,
          Alabama Sales and Use Tax, or Other Transaction Tax (as the case may
          be) paid with respect to such transactions. Notwithstanding anything
          in this Section 10.13(b)(ii) to the contrary, however, no party (the
          "first party") shall be required to take any action requested by the
          other party (the "requesting party") which results or could reasonably
          result in an increase in the amount of Taxes or Transaction Taxes
          imposed upon the first party or its Affiliates, unless the requesting
          party agree to indemnify the first party and its Affiliates for the
          amount of any such increase in Taxes or Transaction Taxes. Further, no
          party will be required to take any action requested by the other party
          that is not based on accepted tax practice and the legal requirements
          regarding the Transaction Tax involved.

          (iii)  Audits, Litigation, and other Contests. (A) Each party shall
                 --------------------------------------                      
          promptly provide the other party with written notice of any claim, or
          of the commencement of any audit or proceeding, together with copies
          of all correspondence, notices or other documents relating thereto,
          which may result in increased Transaction Taxes.  (B) In the case of
          Alabama Sales and Use Taxes, both Intergraph and USI shall jointly
          control the contest of such sales and use taxes, both Intergraph and
          USI shall keep each other fully informed of all proceedings relating
          to Alabama Sales and Use Taxes, both Intergraph and USI shall take
          such steps as are reasonably requested by the other party in order to
          allow such other party to participate in any contest of such Alabama
          Sales and Use Taxes, and neither Intergraph nor USI shall be permitted
          to settle or compromise the dispute of Alabama Sales and Use Taxes
          without the written consent of the other party. However, either party
          can pay its 50% share of any disputed Alabama Sales and Use Taxes (and
          any related interest, penalties, etc.) at any time by notifying and
          paying to the other party such 50% share of disputed Alabama Sales and
          Use Taxes and any related interest, penalties, etc. that have accrued
          through such date of payment.  In cases where a party (the
          "surrendering party") pays its 50% share of disputed Alabama Sales and
          Use Taxes in accordance with the preceding sentence, the surrendering
          party shall provide the other party (the "continuing party") with
          powers of attorney or other appropriate documents which will enable
          the continuing party to fully control and continue the dispute, shall
          not take any actions or disclose any information that would adversely
          affect the continuing party's conduct or resolution of the dispute,
          and shall be released of any further liability with respect to, and
          shall not share in any favorable resolution of, the disputed Alabama
          Sales and Use Taxes.  (C) The Acquiring Entities shall, in their sole
          discretion, control and direct the conduct of any audit or inquiry or
          any administrative or judicial appeal or other proceeding regarding
          Other Transaction Taxes, each Selling Entity shall provide any
          Acquiring Entity who so requests with powers of attorney or other
          appropriate documents which will enable the Acquiring Entity to
          conduct any such proceeding, and each Selling Entity agrees to furnish
          the Acquiring Entities with such information and documentation as is

                                      80
<PAGE>
 
           reasonably requested by the Acquiring Entities in connection with
           such proceedings. The Acquiring Entity may, in its sole discretion,
           agree to pay, settle, compromise, or concede any contest or claim
           relating to Other Transaction Taxes.

           (iv) Record Retention.  Each party will retain all Tax Returns,
                ----------------                                          
           schedules, material records, workpapers or other documents relating
           to Transaction Taxes until the expiration of the statute of
           limitations (including extensions) for assessing or collecting such
           Transactions Taxes. Before any tax records or documents are
           destroyed, the party holding such records shall notify the other
           party of its intent to destroy them and shall offer any such records
           to the other party. If the other party wishes to receive such
           records, it shall notify the party holding the records or documents
           within 45 days of receipt of notice of the other party's intent to
           destroy, and will be liable for any costs related to the transfer of
           such records.

     10.14 Number and Gender.  Unless the context otherwise requires, the
           -----------------

masculine, feminine and neuter forms in this Agreement shall be mutually
inclusive.

     10.16 Complete Agreement; Counterparts.  This document and the documents
           --------------------------------                                    
(including Exhibits and Schedules) referred to herein, contain the complete
agreement and understanding of the parties hereto and thereto with respect to
the matters covered hereby and thereby, and they rescind and supersede any prior
agreements and understandings which may have in any way related to the subject
matter hereof and thereof, including without limitation those matters set forth
in those certain letters, dated October 10, 1997, November 4, 1997 and January
28, 1998, from EDS to Intergraph specifically therein agreed to be binding upon
EDS and Intergraph.  The express terms hereof control and supersede any course
of performance or usage of the trade inconsistent with any of the terms hereof.
This Agreement may be executed by the parties hereto in several counterparts,
and, when so executed and delivered, shall be an original as against any party
whose signature appears thereon, but all such counterparts shall together
constitute but one and the same instrument.  Each counterpart may consist of a
number of copies hereof each executed by less than all, but together executed by
all, of the parties hereto. This Agreement shall become binding when one or more
counterparts hereof, individually or taken together, shall bear the signatures
of all of the parties reflected hereon as the signatories.  It shall not be
necessary in making proof of this Agreement to produce or account for more than
one such counterpart.  Notwithstanding anything to 

                                      81
<PAGE>
 
the contrary contained in this Agreement, it is the explicit intention of the
parties hereto that no party is making any representation or warranty
whatsoever, express or implied, beyond those expressly given in Articles III and
IV hereof and those expressly set forth in any of the Exhibits hereto,
including, but not limited to, any implied warranty or representation as to
condition, merchantability, fitness for any particular purpose, or suitability
of the Acquired Assets.

     10.17 Severability.  If any provision of this Agreement or the application
           ------------                        
of any such provision to any Person or circumstance, shall be declared
judicially to be invalid, unenforceable or void, such decision shall not have
the effect of invalidating or voiding the remainder of this Agreement, it being
the intent and agreement of the parties that this Agreement shall be deemed
amended by modifying such provision to the extent necessary to render it valid,
legal and enforceable while preserving its intent or, if such modification is
not possible, by substituting therefor another provision that is legal and
enforceable and that achieves the same objective.

     10.18 No Third Party Beneficiaries.  Nothing in this Agreement is intended
           ---------------------------- 
or shall be construed to give any Person, other than the parties hereto, any
legal or equitable right, remedy or claim under or in respect of this Agreement
or any provision contained herein.

     10.19 Inconsistencies.  The provisions of the Closing Agreements supplement
           --------------- 
the provisions of this Agreement; provided, however, that to the extent that the
                                  --------  -------                             
provisions of any Closing Agreement are in any respect inconsistent with the
provisions of this Agreement, the provisions of this Agreement shall govern and
control; provided further that to the extent that the application of Section
         -------- -------                                            -------
10.9 to any instrument of transfer, conveyance and assignment delivered pursuant
- ----                                                                            
to a Closing Agreement would render the transfer, conveyance or assignment
contemplated thereby ineffective or invalid, any governing law provisions
otherwise specified in such instrument of transfer, conveyance and assignment
shall govern and control.

     IN WITNESS WHEREOF, the parties hereto have each caused this Agreement to
be duly executed by their respective duly authorized officers or
representatives, all as of the day and year first above written.

THIS CONTRACT CONTAINS A BINDING ARBITRATION PROVISION WHICH MAY BE ENFORCED BY
THE PARTIES.

                          UNIGRAPHICS SOLUTIONS INC.

                           INDEMNIFICATION AGREEMENT


          THIS AGREEMENT is entered into as of [Date], 1998 ("Agreement"),
between Unigraphics Solutions Inc., a Delaware corporation (the "Company"), and
[Name] ("Indemnitee").

                       BACKGROUND STATEMENT AND RECITALS

          Highly competent and experienced persons are becoming more reluctant
to serve corporations as directors or in other capacities unless they are
provided with adequate protection through insurance and adequate indemnification
against inordinate risks of claims and actions against them arising out of their
service to and activities on behalf of the corporation.

          The Board of Directors of the Company (the "Board") has determined
that the inability to attract and retain such persons would be detrimental to
the best interests of the Company and its stockholders and that the Company
should act to assure such persons that there will be increased certainty of such
protection in the future.

          The Board has also determined that it is reasonable, prudent and
necessary for the Company, in addition to making available directors' and
officers' liability insurance (or otherwise providing for adequate arrangements
of self-insurance), contractually to obligate itself to indemnify such persons
to the fullest extent permitted by applicable law so that they will serve or
continue to serve the Company free from undue concern that they will not be so
indemnified.

          Indemnitee is willing to serve, continue to serve and to take on
additional service for or on behalf of the Company on the condition that he be
so indemnified.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants herein contained, and other good and valuable consideration, the
sufficiency and receipt of which are hereby acknowledged, the parties hereby
agree as follows:

                                   ARTICLE 1

                              CERTAIN DEFINITIONS

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

                                      -1-
<PAGE>
 
          "Change in Control" means a change in control of the Company occurring
after the Public Status Date of a nature that would be required to be reported
in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to
any similar item on any similar schedule or form) under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), whether or not the Company is then
subject to such reporting requirement; provided, however, that, without limiting
the generality of the foregoing, a Change in Control shall be deemed to have
occurred (irrespective of the applicability of the initial clause of this
definition) if at any time after the Public Status Date (a) any "person" (as
such term is used in Sections 13(d) and 14(d) of the Exchange Act, but excluding
(i) any employee benefit plan of the Company or of any subsidiary of the
Company, and (ii) any entity organized, appointed or established by the Company
pursuant to the terms of any such plan) 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 50% or more of the combined voting power
of the Company's then outstanding securities without the prior approval of at
least two-thirds of the members of the whole Board in office immediately prior
to such person attaining such percentage interest; (b) the Company is a party to
a merger, consolidation, share exchange, sale of assets or other reorganization,
or a proxy contest, as a consequence of which members of the Board in office
immediately prior to such transaction or event constitute less than a majority
of the whole Board thereafter; or (c) during any period of two consecutive
years, individuals who at the beginning of such period constituted members of
the Board (including for this purpose any new member whose election or
nomination for election by the Company's stockholders was approved by at least
two-thirds of the members of the whole Board then still in office who were
members of the Board at the beginning of such period) cease for any reason to
constitute a majority of the whole Board.  Notwithstanding the foregoing, a
Change in Control shall not be deemed to have occurred solely as a result of
Electronic Data Systems Corporation (or a successor corporation) remaining or
becoming the beneficial owner of 50% or more of the combined voting power of the
Company's then outstanding securities.

          "Claim" means an actual or threatened claim or request for relief.

          "Corporate Status" means the status of a person who is or was a
director, nominee for director, officer, employee, agent or fiduciary of the
Company or of any other corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise which such person is or was serving at the
request of the Company.

          "Disinterested Director," with respect to any request by Indemnitee
for indemnification hereunder, means a director of the Company who neither is
nor was a party to the Proceeding or subject to a Claim, issue or matter in
respect of which indemnification is sought by Indemnitee.

          "DGCL" means the Delaware General Corporation Law and any successor
statute thereto as either of them may be amended from time to time.

                                      -2-
<PAGE>
 
          "Expenses" means all attorneys' fees, retainers, court costs,
transcript costs, fees of experts, witness fees, travel expenses, duplicating
costs, printing and binding costs, telephone charges, postage, delivery service
fees and all other disbursements or expenses of the types customarily incurred
in connection with prosecuting, defending, preparing to prosecute or defend,
investigating, being or preparing to be a witness in, or participating in
(including on appeal), a Proceeding.

          "Independent Counsel" means a law firm, or a member of a law firm,
that is experienced in matters of corporation law and neither contemporaneously
is, nor in the five years theretofore has been, retained to represent (a) the
Company or Indemnitee in any matter material to either such party, (b) any other
party to the Proceeding giving rise to a claim for indemnification hereunder or
(c) the beneficial owner, directly or indirectly, of securities of the Company
representing 20% or more of the combined voting power of the Company's then
outstanding voting securities (other than, in each such case, with respect to
matters concerning the rights of Indemnitee under this Agreement, or of other
indemnitees under similar indemnification agreements).  Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards of professional conduct then prevailing, would
have a conflict of interest in representing either the Company or Indemnitee in
an action to determine Indemnitee's rights under this Agreement.

          "person" shall have the meaning ascribed to such term in Sections
13(d) and 14(d) of the Exchange Act.

          "Proceeding" means any threatened, pending or completed action, suit,
arbitration, alternate dispute resolution mechanism, administrative hearing or
any other proceeding, whether civil, criminal, administrative or investigative
and whether or not based upon events occurring, or actions taken, before the
date hereof (except any of the foregoing initiated by Indemnitee pursuant to
Article 6 or Section 7.8 to enforce his rights under this Agreement), and any
inquiry or investigation that could lead to, and any appeal in or related to,
any such action, suit, arbitration, alternative dispute resolution mechanism,
hearing or proceeding.

          "Public Status Date" means the first date on which the Company has
outstanding a class of equity securities registered under the Exchange Act.

                                   ARTICLE 2

                            SERVICES BY INDEMNITEE

          Section 2.1  Services.  Indemnitee agrees to serve, or continue to
serve, as a director of the Company.  Indemnitee may from time to time also
agree to serve, as the Company may request from time to time, as a director,
officer, employee, agent or fiduciary of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise. Indemnitee and the
Company each acknowledge that they have entered into this Agreement as a means
of inducing Indemnitee to serve, or continue to serve, the Company in such
capacities. 

                                      -3-
<PAGE>
 
Indemnitee may at any time and for any reason resign from such position or
positions (subject to any other contractual obligation or any obligation imposed
by operation of law). The Company shall have no obligation under this Agreement
to continue Indemnitee in any such position or positions.


                                   ARTICLE 3

                                INDEMNIFICATION

          Section 3.1  General.  The Company shall indemnify, and advance
Expenses to, Indemnitee to the fullest extent permitted by applicable law in
effect on the date hereof and to such greater extent as applicable law may
thereafter from time to time permit.  The rights of Indemnitee provided under
the preceding sentence shall include, but shall not be limited to, the right to
be indemnified and to have Expenses advanced in all Proceedings to the fullest
extent permitted by Section 145 of the DGCL.  The provisions set forth in this
Agreement are provided in addition to and as a means of furtherance and
implementation of, and not in limitation of, the obligations expressed in this
Article 3.

          Section 3.2  Proceedings Other Than by or in Right of the Company.
Indemnitee shall be entitled to indemnification pursuant to this Section 3.2 if,
by reason of his Corporate Status, he was, is or is threatened to be made, a
party to any Proceeding, other than a Proceeding by or in the right of the
Company.  Pursuant to this Section 3.2, the Company shall indemnify Indemnitee
against Expenses, judgments, penalties, fines and amounts paid in settlement
(including all interest, assessments and other charges paid or payable in
connection with any such Expenses, judgments, penalties, fines and amounts paid
in settlement) actually and reasonably incurred by him or on his behalf in
connection with such Proceeding or any Claim, issue or matter therein, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company, and with respect to any criminal
Proceeding, had no reasonable cause to believe his conduct was unlawful.
Nothing in this Section 3.2 shall limit the benefits of Section 3.1 or any other
Section hereunder.

          Section 3.3  Proceedings by or in Right of the Company.  Indemnitee
shall be entitled to indemnification pursuant to this Section 3.3 if, by reason
of his Corporate Status, he was, is or is threatened to be made, a party to any
Proceeding brought by or in the right of the Company to procure a judgment in
its favor.  Pursuant to this Section 3.3, the Company shall indemnify Indemnitee
against Expenses actually and reasonably incurred by him or on his behalf in
connection with such Proceeding or any Claim, issue or matter therein, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company.  Notwithstanding the foregoing, no
indemnification against such Expenses shall be made in respect of any Claim,
issue or matter in such Proceeding as to which Indemnitee shall have been
adjudged to be liable to the Company if applicable law prohibits such
indemnification; provided, however, that, if applicable law so permits,
indemnification against such Expenses shall nevertheless be made by the Company
in such event if and only to the extent that the Court 

                                      -4-
<PAGE>
 
of Chancery of the State of Delaware or other court of competent jurisdiction
(the "Court"), or the court in which such Proceeding shall have been brought or
is pending, shall so determine. Nothing in this Section 3.3 shall limit the
benefits of Section 3.1 or any other Section hereunder.

                                   ARTICLE 4

                                   EXPENSES

          Section 4.1  Expenses of a Party Who Is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement to the contrary (except as
set forth in Section 7.2(c) or 7.6), and without a requirement for any
determination described in Section 5.2, the Company shall indemnify Indemnitee
against all Expenses actually and reasonably incurred by him or on his behalf in
connection with any Proceeding to which Indemnitee was or is a party by reason
of his Corporate Status and in which Indemnitee is successful, on the merits or
otherwise.  If Indemnitee is not wholly successful, on the merits or otherwise,
in a Proceeding but is successful, on the merits or otherwise, as to any Claim,
issue or matter in such Proceeding, the Company shall indemnify Indemnitee
against all Expenses actually and reasonably incurred by him or on his behalf
relating to each successfully resolved Claim, issue or matter.  For purposes of
this Section 4.1 and without limitation, the termination of a Claim, issue or
matter in a Proceeding by dismissal, with or without prejudice, shall be deemed
to be a successful result as to such Claim, issue or matter.

          Section 4.2  Expenses of a Witness or Non-Party.  Notwithstanding any
other provision of this Agreement to the contrary, to the extent that Indemnitee
is, by reason of his Corporate Status, a witness or otherwise participates in
any Proceeding at a time when he is not a party in the Proceeding, the Company
shall indemnify him against all Expenses actually and reasonably incurred by him
or on his behalf in connection therewith.

          Section 4.3  Advancement of Expenses.  The Company shall pay all
reasonable Expenses incurred by or on behalf of Indemnitee in connection with
any Proceeding, whether brought by or in the right of the Company or otherwise,
in advance of any determination with respect to entitlement to indemnification
pursuant to Article 5 within 15 days after the receipt by the Company of a
written request from Indemnitee requesting such payment or payments from time to
time, whether prior to or after final disposition of such Proceeding.  Such
statement or statements shall reasonably evidence the Expenses incurred by
Indemnitee.  Indemnitee hereby undertakes and agrees that he will reimburse and
repay the Company for any Expenses so advanced to the extent that it shall
ultimately be determined (in a final adjudication by a court from which there is
no further right of appeal or in a final adjudication of an arbitration pursuant
to Section 6.1 if Indemnitee elects to seek such arbitration) that Indemnitee is
not entitled to be indemnified by the Company against such Expenses.

                                   ARTICLE 5
                  PROCEDURE FOR DETERMINATION OF ENTITLEMENT
                              TO INDEMNIFICATION

          Section 5.1  Request by Indemnitee.  To obtain indemnification under
this Agreement, Indemnitee shall submit to the Company a written request,
including therein or therewith such documentation and information as is
reasonably available to Indemnitee and is reasonably necessary to determine
whether and to what extent Indemnitee is entitled to indemnification.  The
Secretary or an Assistant Secretary of the Company shall, promptly upon receipt
of such a request for indemnification, advise the members of the Board in
writing that Indemnitee has requested indemnification.

          Section 5.2  Determination of Request.  Upon written request by
Indemnitee for indemnification pursuant to Section 5.1, a determination, if
required by applicable law, with respect to Indemnitee's entitlement thereto
shall be made in the specific case as follows:

                  (a)  If a Change in Control shall have occurred, by 
     Independent Counsel in a written opinion to the Board, a copy of which
     shall be delivered to Indemnitee unless Indemnitee shall request that such
     determination be made by the Disinterested Directors, in which case in the
     manner provided for in clause (i) of paragraph (b) below;

                  (b)  If a Change in Control shall not have occurred, (i) by 
     a majority vote of the Disinterested Directors, even though less than a
     quorum of the Board, or (ii) if there are no Disinterested Directors, or if
     such Disinterested Directors so direct, by Independent Counsel in a written
     opinion to the Board, a copy of which shall be delivered to the Indemnitee,
     or (iii) if Indemnitee and the Company mutually agree, by the stockholders
     of the Company; or

                  (c)  As provided in Section 5.4(b).

If it is so determined that Indemnitee is entitled to indemnification hereunder,
payment to Indemnitee shall be made within 15 days after such determination.
Indemnitee shall cooperate with the person or persons making such determination
with respect to Indemnitee's entitlement to indemnification, including providing
to such person upon reasonable advance request any documentation or information
that is not privileged or otherwise protected from disclosure and that is
reasonably available to Indemnitee and reasonably necessary for such
determination.  Any costs or expenses (including attorneys' fees and
disbursements) incurred by Indemnitee in so cooperating with the person or
persons making such determination shall be borne by the Company (irrespective of
the determination as to Indemnitee's entitlement to indemnification), and the
Company shall indemnify and hold harmless Indemnitee therefrom.

          Section 5.3  Independent Counsel.  If a Change in Control shall not
have occurred and the determination of entitlement to indemnification is to be
made by Independent Counsel, the Independent Counsel shall be selected by (a) a
majority vote of the Disinterested 

                                      -6-
<PAGE>
 
Directors, even though less than a quorum of the Board or (b) if there are no
Disinterested Directors, by a majority vote of the Board, and the Company shall
give written notice to Indemnitee, within 10 days after receipt by the Company
of Indemnitee's request for indemnification, specifying the identity and address
of the Independent Counsel so selected. If a Change in Control shall have
occurred and the determination of entitlement to indemnification is to be made
by Independent Counsel, the Independent Counsel shall be selected by Indemnitee,
and Indemnitee shall give written notice to the Company, within 10 days after
submission of Indemnitee's request for indemnification, specifying the identity
and address of the Independent Counsel so selected (unless Indemnitee shall
request that such selection be made by the Disinterested Directors, in which
event the Company shall give written notice to Indemnitee, within 10 days after
receipt of Indemnitee's request for the Disinterested Directors to make such
selection, specifying the identity and address of the Independent Counsel so
selected). In either event, (i) such notice to Indemnitee or the Company, as the
case may be, shall be accompanied by a written affirmation of the Independent
Counsel so selected that it satisfies the requirements of the definition of
"Independent Counsel" in Article 1 and that it agrees to serve in such capacity
and (ii) Indemnitee or the Company, as the case may be, may, within seven days
after such written notice of selection shall have been given, deliver to the
Company or to Indemnitee, as the case may be, a written objection to such
selection. Any objection to selection of Independent Counsel pursuant to this
Section 5.3 may be asserted only on the ground that the Independent Counsel so
selected does not meet the requirements of the definition of "Independent
Counsel" in Article 1, and the objection shall set forth with particularity the
factual basis of such assertion. If such written objection is timely made, the
Independent Counsel so selected may not serve as Independent Counsel unless and
until the Court has determined that such objection is without merit. In the
event of a timely written objection to a choice of Independent Counsel, the
party originally selecting the Independent Counsel shall have seven days to make
an alternate selection of Independent Counsel and to give written notice of such
selection to the other party, after which time such other party shall have five
days to make a written objection to such alternate selection. If, within 30 days
after submission of Indemnitee's request for indemnification pursuant to Section
5.1, no Independent Counsel shall have been selected and not objected to, either
the Company or Indemnitee may petition the Court for resolution of any objection
that shall have been made by the Company or Indemnitee to the other's selection
of Independent Counsel and/or for the appointment as Independent Counsel of a
person selected by the Court or by such other person as the Court shall
designate, and the person with respect to whom an objection is so resolved or
the person so appointed shall act as Independent Counsel under Section 5.2. The
Company shall pay any and all reasonable fees and expenses incurred by such
Independent Counsel in connection with acting pursuant to Section 5.2, and the
Company shall pay all reasonable fees and expenses incident to the procedures of
this Section 5.3, regardless of the manner in which such Independent Counsel was
selected or appointed. Upon the due commencement of any judicial proceeding or
arbitration pursuant to Section 6.1, Independent Counsel shall be discharged and
relieved of any further responsibility in such capacity (subject to the
applicable standards of professional conduct then prevailing).

          Section 5.4  Presumptions and Effect of Certain Proceedings.

                  (a)  Indemnitee shall be presumed to be entitled to
     indemnification under this Agreement upon submission of a request for
     indemnification pursuant to Section 5.1, and the Company shall have the
     burden of proof in overcoming that presumption in reaching a determination
     contrary to that presumption.  Such presumption shall be used by
     Independent Counsel (or other person or persons determining entitlement to
     indemnification) as a basis for a determination of entitlement to
     indemnification unless the Company provides information sufficient to
     overcome such presumption by clear and convincing evidence.

                  (b)  If the person or persons empowered or selected under this
     Article 5 to determine whether Indemnitee is entitled to indemnification
     shall not have made a determination within 60 days after receipt by the
     Company of Indemnitee's request for indemnification, the requisite
     determination of entitlement to indemnification shall be deemed to have
     been made and Indemnitee shall be entitled to such indemnification, absent
     (i) a knowing misstatement by Indemnitee of a material fact, or knowing
     omission of a material fact necessary to make Indemnitee's statement not
     materially misleading, in connection with Indemnitee's request for
     indemnification, or (ii) a prohibition of such indemnification under
     applicable law; provided, however, that such 60-day period may be extended
     for a reasonable time, not to exceed an additional 30 days, if the person
     making the determination with respect to entitlement to indemnification in
     good faith requires such additional time for the obtaining or evaluating of
     documentation and/or information relating to such determination; provided
     further, that the 60-day limitation set forth in this Section 5.4(b) shall
     not apply and such period shall be extended as necessary (i) if within 30
     days after receipt by the Company of Indemnitee's request for
     indemnification under Section 5.1 Indemnitee and the Company have agreed,
     and the Board has resolved, to submit such determination to the
     stockholders of the Company pursuant to Section 5.2(b) for their
     consideration at an annual meeting of stockholders to be held within 90
     days after such agreement and such determination is made thereat, or a
     special meeting of stockholders for the purpose of making such
     determination to be held within 60 days after such agreement and such
     determination is made thereat, or (ii) if the determination of entitlement
     to indemnification is to be made by Independent Counsel, in which case the
     applicable period shall be as set forth in clause (c) of Section 6.1.

                  (c)  The termination of any Proceeding or of any Claim, issue
     or matter by judgment, order, settlement (whether with or without court
     approval) or conviction, or upon a plea of nolo contendere or its
     equivalent, shall not by itself adversely affect the rights of Indemnitee
     to indemnification or create a presumption that Indemnitee did not act in
     good faith or in a manner that he reasonably believed to be in or not
     opposed to the best interests of the Company or, with respect to any
     criminal Proceeding, that Indemnitee had reasonable cause to believe that
     his conduct was unlawful. Indemnitee shall be deemed to have been found
     liable in respect of any Claim, issue or matter only 

                                      -8-
<PAGE>
 
     after he shall have been so adjudged by the Court after exhaustion of all
     appeals therefrom.

                                   ARTICLE 6

                        CERTAIN REMEDIES OF INDEMNITEE

          Section 6.1  Indemnitee Entitled to Adjudication in an Appropriate
Court.  If (a) a determination is made pursuant to Article 5 that Indemnitee is
not entitled to indemnification under this Agreement, (b) there has been any
failure by the Company to make timely payment or advancement of any amounts due
hereunder, or (c) the determination of entitlement to indemnification is to be
made by Independent Counsel and such determination shall not have been made and
delivered in a written opinion within 90 days after the latest of (i) such
Independent Counsel's being appointed, (ii) the overruling by the Court of
objections to such counsel's selection or (iii) expiration of all periods for
the Company or Indemnitee to object to such counsel's selection, Indemnitee
shall be entitled to commence an action seeking an adjudication in the Court of
his entitlement to such indemnification or advancement of Expenses.
Alternatively, Indemnitee, at his option, may seek an award in arbitration to be
conducted by a single arbitrator pursuant to the commercial arbitration rules of
the American Arbitration Association.  Indemnitee shall commence such action
seeking an adjudication or an award in arbitration within 180 days following the
date on which Indemnitee first has the right to commence such action pursuant to
this Section 6.1, or such right shall expire.  The Company shall not oppose
Indemnitee's right to seek any such adjudication or award in arbitration.

          Section 6.2  Adverse Determination Not to Affect any Judicial
Proceeding.  If a determination shall have been made pursuant to Article 5 that
Indemnitee is not entitled to indemnification under this Agreement, any judicial
proceeding or arbitration commenced pursuant to this Article 6 shall be
conducted in all respects as a de novo trial or arbitration on the merits, and
Indemnitee shall not be prejudiced by reason of such initial adverse
determination.  In any judicial proceeding or arbitration commenced pursuant to
this Article 6, Indemnitee shall be presumed to be entitled to indemnification
or advancement of Expenses, as the case may be, under this Agreement and the
Company shall have the burden of proof in overcoming such presumption and to
show by clear and convincing evidence that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

          Section 6.3  Company Bound by Determination Favorable to Indemnitee in
any Judicial Proceeding or Arbitration.  If a determination shall have been made
or deemed to have been made pursuant to Article 5 that Indemnitee is entitled to
indemnification, the Company shall be irrevocably bound by such determination in
any judicial proceeding or arbitration commenced pursuant to this Article 6 and
shall be precluded from asserting that such determination has not been made or
that the procedure by which such determination was made is not valid, binding
and enforceable, in each such case absent (a) a knowing misstatement by
Indemnitee of a material fact, or a knowing omission of a material fact
necessary to make a 

                                      -9-
<PAGE>
 
statement by Indemnitee not materially misleading, in connection with
Indemnitee's request for indemnification or (b) a prohibition of such
indemnification under applicable law.

          Section 6.4  Company Bound by the Agreement.  The Company shall be
precluded from asserting in any judicial proceeding or arbitration commenced
pursuant to this Article 6 that the procedures and presumptions of this
Agreement are not valid, binding and enforceable and shall stipulate in any such
court or before any such arbitrator that the Company is bound by all the
provisions of this Agreement.

          Section 6.5  Indemnitee Entitled to Expenses of Judicial Proceeding.
If Indemnitee seeks a judicial adjudication of or an award in arbitration to
enforce his rights under, or to recover damages for breach of, this Agreement,
Indemnitee shall be entitled to recover from the Company, and the Company shall
indemnify Indemnitee against, any and all expenses (of the types described in
the definition of Expenses in Article 1) actually and reasonably incurred by him
in such judicial adjudication or arbitration but only if Indemnitee prevails
therein.  If it shall be determined in such judicial adjudication or arbitration
that Indemnitee is entitled to receive part but not all of the indemnification
or advancement of expenses or other benefit sought, the expenses incurred by
Indemnitee in connection with such judicial adjudication or arbitration shall be
equitably allocated between the Company and Indemnitee.  Notwithstanding the
foregoing, if a Change in Control shall have occurred, Indemnitee shall be
entitled to indemnification under this Section 6.5 regardless of whether
Indemnitee ultimately prevails in such judicial adjudication or arbitration.


                                   ARTICLE 7

                                 MISCELLANEOUS

          Section 7.1  Non-Exclusivity.

                  (a)  The rights of Indemnitee to receive indemnification and
     advancement of Expenses under this Agreement shall not be deemed exclusive
     of any other rights to which Indemnitee may at any time be entitled under
     applicable law, the Certificate of Incorporation or Bylaws of the Company,
     any other agreement, vote of stockholders or a resolution of directors, or
     otherwise.  No amendment or alteration of the Certificate of Incorporation
     or Bylaws of the Company or any provision thereof shall adversely affect
     Indemnitee's rights hereunder and such rights shall be in addition to any
     rights Indemnitee may have under the Company's Certificate of
     Incorporation, Bylaws and the DGCL or otherwise.  To the extent that there
     is a change in the DGCL or other applicable law (whether by statute or
     judicial decision) that allows greater indemnification by agreement than
     would be afforded currently under the Company's Certificate of
     Incorporation or Bylaws and this Agreement, it is the intent of the parties
     hereto that the Indemnitee shall enjoy by virtue of this Agreement the
     greater benefit so afforded by such change.

                                      -10-
<PAGE>
 
                  (b)  The Company shall not amend the Bylaws of the Company 
     in a manner that adversely affects Indemnitee's rights to indemnification
     thereunder existing as of the date hereof until the six-year anniversary of
     the Public Status Date.

          Section 7.2  Insurance and Subrogation.

                  (a)  To the extent the Company maintains an insurance policy
     or policies providing liability insurance for directors, officers,
     employees, agents or fiduciaries of the Company or of any other
     corporation, partnership, joint venture, trust, employee benefit plan or
     other enterprise that such person serves at the request of the Company,
     Indemnitee shall be covered by such policy or policies in accordance with
     its or their terms to the maximum extent of the coverage available for any
     such director, officer, employee, agent or fiduciary under such policy or
     policies.

                  (b)  In the event of any payment by the Company under this
     Agreement, the Company shall be subrogated to the extent of such payment to
     all of the rights of recovery of Indemnitee, who shall execute all papers
     required and take all action necessary to secure such rights, including
     execution of such documents as are necessary to enable the Company to bring
     suit to enforce such rights.

                  (c) The Company shall not be liable under this Agreement to
     make any payment of amounts otherwise indemnifiable hereunder if and to the
     extent that Indemnitee has otherwise actually received such payment under
     the Company's Certificate of Incorporation or Bylaws or any insurance
     policy, contract, agreement or otherwise.

          Section 7.3  Certain Settlement Provisions.  The Company shall have no
obligation to indemnify Indemnitee under this Agreement for amounts paid in
settlement of a Proceeding or Claim without the Company's prior written consent.
The Company shall not settle any Proceeding or Claim in any manner that would
impose any fine or other obligation on 12 Indemnitee without Indemnitee's prior
written consent. Neither the Company nor Indemnitee shall unreasonably withhold
their consent to any proposed settlement.

          Section 7.4  Duration of Agreement.  This Agreement shall continue for
so long as Indemnitee serves as a director, nominee for director, officer,
employee, agent or fiduciary of the Company or, at the request of the Company,
as a director, nominee for director, officer, employee, agent or fiduciary of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise, and thereafter shall survive until and terminate upon the
latest to occur of (a) the expiration of 10 years after the latest date that
Indemnitee shall have ceased to serve in any such capacity; (b) the final
termination of all pending Proceedings in respect of which Indemnitee is granted
rights of indemnification or advancement of Expenses hereunder and of any
proceeding commenced by Indemnitee pursuant to Article 6 relating thereto; or
(c) the 

                                      -11-
<PAGE>
 
expiration of all statutes of limitation applicable to possible Claims arising
out of Indemnitee's Corporate Status.

          Section 7.5  Notice by Each Party.  Indemnitee shall promptly notify
the Company in writing upon being served with any summons, citation, subpoena,
complaint, indictment, information or other document or communication relating
to any Proceeding or Claim for which Indemnitee may be entitled to
indemnification or advancement of Expenses hereunder; provided, however, that
any failure of Indemnitee to so notify the Company shall not adversely affect
Indemnitee's rights under this Agreement except to the extent the Company shall
have been materially prejudiced as a direct result of such failure.  The Company
shall notify promptly Indemnitee in writing, as to the pendency of any
Proceeding or Claim that may involve a claim against the Indemnitee for which
Indemnitee may be entitled to indemnification or advancement of Expenses
hereunder.

          Section 7.6  Certain Persons Not Entitled to Indemnification.
Notwithstanding any other provision of this Agreement to the contrary,
Indemnitee shall not be entitled to indemnification or advancement of Expenses
hereunder with respect to any Proceeding or any Claim, issue or matter therein,
brought or made by Indemnitee against the Company or any affiliate of the
Company, except as specifically provided in Article 5 or Article 6.

          Section 7.7  Indemnification for Negligence, Gross Negligence, etc.
Without limiting the generality of any other provision hereunder, it is the
express intent of this Agreement that Indemnitee be indemnified and Expenses be
advanced regardless of Indemnitee's acts of negligence, gross negligence or
intentional or willful misconduct to the extent that indemnification and
advancement of Expenses is allowed pursuant to the terms of this Agreement and
under applicable law.

          Section 7.8  Enforcement.  The Company agrees that its execution of
this Agreement shall constitute a stipulation by which it shall be irrevocably
bound in any court or arbitration in which a proceeding by Indemnitee for
enforcement of his rights hereunder shall have been commenced, continued or
appealed, that its obligations set forth in this Agreement are unique and
special, and that failure of the Company to comply with the provisions of this
Agreement will cause irreparable and irremediable injury to Indemnitee, for
which a remedy at law will be inadequate.  As a result, in addition to any other
right or remedy he may have at law or in equity with respect to breach of this
Agreement, Indemnitee shall be entitled to injunctive or mandatory relief
directing specific performance by the Company of its obligations under this
Agreement.

          Section 7.9  Successors and Assigns.  All of the terms and provisions
of this Agreement shall be binding upon, shall inure to the benefit of and shall
be enforceable by the parties hereto and their respective successors, assigns,
heirs, executors, administrators, legal representatives.  The Company shall
require and cause any direct or indirect successor (whether by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company, by written agreement in form and substance reasonably
satisfactory to 

                                      -12-
<PAGE>
 
Indemnitee, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform if
no such succession had taken place.

          Section 7.10  Amendment.  This Agreement may not be modified or
amended except by a written instrument executed by or on behalf of each of the
parties hereto.

          Section 7.11  Waivers.  The observance of any term of this Agreement
may be waived (either generally or in a particular instance and either
retroactively or prospectively) by the party entitled to enforce such term only
by a writing signed by the party against which such waiver is to be asserted.
Unless otherwise expressly provided herein, no delay on the part of any party
hereto in exercising any right, power or privilege hereunder shall operate as a
waiver thereof, nor shall any waiver on the part of any party hereto of any
right, power or privilege hereunder operate as a waiver of any other right,
power or privilege hereunder nor shall any single or partial exercise of any
right, power or privilege hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder.

          Section 7.12  Entire Agreement.  This Agreement and the documents
expressly referred to herein constitute the entire agreement between the parties
hereto with respect to the matters covered hereby, and any other prior or
contemporaneous oral or written understandings or agreements with respect to the
matters covered hereby are expressly superseded by this Agreement.

          Section 7.13  Severability.  If any provision of this Agreement
(including any provision within a single section, paragraph or sentence) or the
application of such provision to any person or circumstance, shall be judicially
declared to be invalid, unenforceable or void, such decision will not have the
effect of invalidating or voiding the remainder of this Agreement or affect the
application of such provision to other persons or circumstances, it being the
intent and agreement of the parties that this Agreement shall be deemed amended
by modifying such provision to the extent necessary to render it valid, legal
and enforceable while preserving its intent, or if such modification is not
possible, by substituting therefor another provision that is valid, legal and
unenforceable and that achieves the same objective.  Any such finding of
invalidity or unenforceability shall not prevent the enforcement of such
provision in any other jurisdiction to the maximum extent permitted by
applicable law.

          Section 7.14  Notices.  All notices and other communications hereunder
shall be in writing and shall be deemed given upon (a) transmitter's
confirmation of a receipt of a facsimile transmission, (b) confirmed delivery of
a standard overnight courier or when delivered by hand or (c) the expiration of
five business days after the date mailed by certified or registered mail (return
receipt requested), postage prepaid, to the parties at the following addresses
(or at such other addresses for a party as shall be specified by like notice):

                  (a)   The article and section headings contained in this
     Agreement are for reference purposes only and shall not affect in any way
     the meaning or interpretation of this Agreement. As used in this Agreement,
     unless otherwise provided to the contrary, (i) all references to days shall
     be deemed references to calendar days and (ii) any reference to a "Section"
     or "Article" shall be deemed to refer to a section or article of this
     Agreement. The words "hereof," "herein" and "hereunder" and words of
     similar import referring to this Agreement refer to this Agreement as a
     whole and not to any particular provision of this Agreement. Whenever the
     words "include," "includes" or "including" are used in this Agreement, they
     shall be deemed to be followed by the words "without limitation." Unless
     otherwise specifically provided for herein, the term "or" shall not be
