THE COMPANY
 
   
     We are a worldwide provider of information technology services and business
solutions to a broad range of clients. We serve our clients by delivering
services and solutions focused on each client's needs, with particular emphasis
on helping clients more effectively serve their customers.
    
 
   
     We integrate three core disciplines in providing information technology
solutions and services to our clients:
    
 
     - business integration;
 
     - systems integration and applications development; and
 
     - information technology infrastructure services.
 
   
     Business integration services include working with clients to develop and
implement business strategy, information technology strategy, process redesign,
and change management. Systems integration and applications development include
the design and implementation of information technology systems for clients,
including both custom-developed and packaged software. Information technology
infrastructure services combine information technology outsourcing, staffing,
and infrastructure management.
    
 
     Our approach is to provide clients with an "integrated service
offering" -- a combination of multiple disciplines that assists our clients in
improving their business operations or in creating new business offerings. With
this approach, we are able to create long-term relationships with our clients
that begin with an analysis of our clients' business strategies and continue
through the implementation of information technology solutions and the
realization of the clients' goals.
 
     In marketing our services, we are primarily focused on four industries:
Financial Services, Energy, Healthcare, and Travel and Transportation. We target
these industries to capture the opportunities arising from these industries'
rapid rates of change, growth, and the increasing importance of information
technology in driving and managing this change and growth. We also have
significant clients in the Communications and Media and Manufacturing industries
and continually evaluate additional industries for future growth opportunities.
 
THE PEROT SYSTEMS APPROACH
 
   
     We provide services on a worldwide basis that are uniquely structured to
each client. We combine the appropriate industry expertise and core disciplines
to solve the client's business problems and implement new strategies to generate
future growth. Our approach includes:
    
 
     - Providing Integrated Service Offerings. We combine our business
       integration, systems integration and applications development, and
       information technology infrastructure services to analyze and address our
       clients' business and information technology challenges and
       opportunities. Rather than narrowly focusing on isolated problems, we
       design our integrated service offerings to allow a client to achieve
       growth and efficiencies through the implementation of broader business
       solutions.
 
     - Structuring Creative Long-Term Relationships. We seek to create long-term
       relationships with clients that begin with the initial analysis of a
       client's business and information technology problems and opportunities
       and continue through implementation of solutions and the realization of
       benefits. We strive to maximize revenues and client satisfaction by
       creatively structuring contracts with economic incentives that link our
       compensation to the client's business results or the level of our
       performance.
 
                                        3
<PAGE>   6
 
   
     - Employing Multi-Disciplinary Teams. We employ multi-disciplinary teams of
       associates with industry-specific expertise and associates with superior
       technical skills to best formulate and implement integrated information
       technology solutions for clients.
    
 
     - Formulating Unbiased Client-Based Solutions. We analyze our clients'
       business problems and opportunities from the perspective of the clients
       and their customers. We then impartially assemble the best combination of
       our services and third party products to meet the clients' needs.
 
PEROT SYSTEMS GROWTH STRATEGY
 
     Our strategic objective is to become the provider of choice for information
technology services and business solutions. Key elements of our growth strategy
include:
 
     - Expand Value-Added Service Offerings. We believe that services aimed at
       growing a client's business and making a client more productive and
       competitive will create more value for our clients, and accordingly
       generate more growth, than traditional technology functional services.
       Our strategy includes an increasing focus on systems integration and
       applications development and business integration services, supported by
       value-added information technology infrastructure services.
 
     - Target Rapidly Changing Industries. We target rapidly changing industries
       that are substantially affected by the increasing need for information
       technology. We utilize associates with operating expertise in these
       specific industries as a competitive advantage in providing superior
       services to our clients.
 
     - Create and Leverage Growth Engines. In each industry, we have the
       opportunity to create "growth engines" -- sets of skills, business
       processes, and know-how that, when combined, create leverageable business
       solutions for clients. We can use these growth engines to build our
       presence in our targeted industries and adapt them to develop or enter
       other industries.
 
     - Develop Select Clients. We believe that client selection is key to growth
       and profitability. We target market leaders and aspiring market leaders
       that are committed to using information technology strategically and are
       willing to develop long-term relationships.
 
   
     - Attract, Train, and Retain Associates with Strong Character. We believe
       that attracting, training, and retaining high quality associates are
       essential to our growth. We hire motivated individuals with strong
       character and leadership traits and provide them with ongoing
       technological and leadership skills training. We emphasize retaining our
       associates through challenging work assignments and incentive programs,
       including rewarding outstanding performance with equity interests. More
       than 90% of our associates hold equity interests in our company.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
 
   
     The following summary consolidated financial data for the years ended
December 31, 1997, 1996, and 1995 have been derived from our consolidated
financial statements, which have been audited by PricewaterhouseCoopers LLP,
independent auditors. We derived the following summary consolidated financial
information as of September 30, 1998 and for the nine months ended September 30,
1998 and 1997 from unaudited consolidated financial statements, which, in our
opinion, reflect all adjustments (consisting of only normal and recurring
accruals) necessary to present fairly our financial position and results of
operations for those periods. Interim results do not necessarily indicate the
results that you may expect for any other interim period or for the full year.
You should read this information in conjunction with "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and our
consolidated financial statements and related notes thereto, contained elsewhere
in this Prospectus.

                                  RISK FACTORS
 
   
     You should carefully consider the following risk factors and warnings
before making an investment decision. The risks described below are not the only
ones facing our company. Additional risks that we do not yet know of or that we
currently think are immaterial may also impair our business operations. If any
of the following risks actually occur, our business, financial condition, or
results of operations could be materially and adversely affected. In such case,
the trading price of our Class A Common Stock could decline, and you may lose
all or part of your investment. You should also refer to the other information
set forth in this Prospectus, including our consolidated financial statements
and the related notes.
    
 
     This Prospectus contains forward-looking statements. These statements
relate to future events or our future financial performance. In some cases, you
can identify forward-looking statements by terminology such as "may," "will,"
"should," "expects," "plans," "anticipates," "believes," "estimates,"
"predicts," "potential," or "continue" or the negative of such terms and other
comparable terminology. These statements are only predictions. Actual events or
results may differ materially. In evaluating these statements, you should
specifically consider various factors, including the risks outlined below. These
factors may cause our actual results to differ materially from any
forward-looking statement.
 
LOSS OF MAJOR CLIENTS COULD ADVERSELY AFFECT OUR BUSINESS
 
   
     Our ten largest clients accounted for approximately 65.4% of our revenue
for the nine month period ended September 30, 1998. For the year ended December
31, 1997, our ten largest clients accounted for approximately 64.1% of our
revenue. Only two clients, UBS and East Midlands Electricity, accounted for more
than 10% of our revenue during 1997 and the first nine months of 1998.
    
 
   
     Our largest client is UBS. Approximately 25.4% of our revenue came from
services performed on behalf of UBS for the nine month period ended September
30, 1998. For the year ended December 31, 1997, approximately 27.2% of our
revenue came from UBS. We expect UBS to account for a substantial portion of our
revenue and earnings for the foreseeable future. See "Business -- UBS
Agreements."
    
 
   
     Approximately 11.9% of our revenue came from services performed on behalf
of East Midlands Electricity for the nine month period ended September 30, 1998.
For the year ended December 31, 1997, approximately 10.2% of our revenue came
from East Midlands Electricity. In July 1998, PowerGen plc acquired East
Midlands Electricity from Dominion Resources, Inc. Our agreement with East
Midlands Electricity contains provisions allowing East Midlands Electricity to
terminate the contract in specified circumstances, including the sale of East
Midlands Electricity. See "Business -- Agreement with EME." We cannot assure you
that they will not cancel or modify the contract or that we will maintain our
historic level of revenue or profits from this relationship.
    
 
   
     After UBS and East Midlands Electricity, our next eight largest customers
accounted for approximately 28.2% of our revenue in the first nine months of
1998. Our success depends substantially upon the retention of UBS, East Midlands
Electricity, and a majority of our other major clients as ongoing clients.
Generally, we may lose a client as a result of a merger or acquisition, business
failure, contract expiration, or the selection of another provider of
information technology services. Of our top ten clients as of September 30,
1998, two contracts (representing approximately $53 million in revenue during
1997) will expire in 1998 and one contract (representing approximately $26
million in revenue during 1997) will expire in 1999. Of the three relationships,
two are long-term contractual relationships that we do not expect will be
renewed and one is a short-term agreement that we believe will be renewed. We
cannot guarantee that we will be able to retain long-term relationships or
secure renewals of short-term relationships with our major clients in the
future. See "-- Our Contracts Contain Termination Provisions and Pricing Risks."
    
 
CHANGES IN OUR UBS RELATIONSHIP AND VARIABILITY OF PROFITS FROM UBS COULD
ADVERSELY AFFECT OUR BUSINESS
 
     Our relationship with UBS is a long-term strategic relationship that we
formed by entering into several agreements with UBS in January 1996. These
contracts were renegotiated in April 1997 and June 1998. The
 
                                        7
<PAGE>   10
 
April 1997 renegotiation reduced the term of the agreements from 25 years to ten
years beginning January 1997. We cannot guarantee that our current relationship
with UBS will continue on the same terms in the future.
 
     Revenue derived from this relationship depends upon the level of services
we perform, which may vary from period to period depending on UBS's
requirements. The agreement with UBS that covers a majority of our business with
UBS entitles us to recover our costs plus an annual fee in an agreed amount with
a bonus or penalty that can cause this annual fee to vary up or down by as much
as 15%, depending on our level of performance as determined by UBS.
Determination of whether our performance merits a bonus or a penalty depends on
many subjective factors, including service quality, client satisfaction, and our
effectiveness in assisting UBS in meeting its business goals. As a result, we
cannot predict with certainty the future level of revenue or profit from our
relationship with UBS. See "Business -- UBS Agreements."
 
FAILURE TO RECRUIT, TRAIN, AND RETAIN SKILLED PERSONNEL COULD INCREASE COSTS OR
LIMIT GROWTH
 
   
     We must continue to grow internally by hiring and training
technically-skilled people in order to perform services under our existing
contracts and new contracts that we will enter into. The people capable of
filling these positions are in great demand and recruiting and training such
personnel require substantial resources. We have to pay an increasing amount to
hire and retain a technically-skilled workforce. Our business also experiences
significant turnover of technically-skilled people. These factors create
variations and uncertainties in our compensation expense and directly affect our
profits. If we fail to attract, train, and retain sufficient numbers of these
technically-skilled people, our business, financial condition, and results of
operations will be materially and adversely affected.
    
 
   
     We have issued a substantial number of options to purchase shares of Class
A Common Stock to our associates prior to this offering. Following this
offering, we expect to continue to issue options to our associates to reward
performance and encourage retention. The exercise of any additional options
issued by us could adversely affect the prevailing market price of the Class A
Common Stock.
    
 
WE COULD LOSE RIGHTS TO OUR COMPANY NAME
 
     We do not own the right to our company name. In 1988, we entered into a
license agreement with Ross Perot and the Perot Systems Family Corporation that
allows us to use the name "Perot" and "Perot Systems" in our business on a
royalty-free basis. Mr. Perot and the Perot Systems Family Corporation may
terminate this agreement at any time and for any reason. Beginning one year
following such a termination, we would not be allowed to use the names "Perot"
or "Perot Systems" in our business. Mr. Perot's or the Perot Systems Family
Corporation's termination of our license agreement could materially and
adversely affect our business, financial condition, and results of operations.
See "Certain Relationships and Related Transactions."
 
   
ROSS PEROT'S STOCK OWNERSHIP PROVIDES SUBSTANTIAL CONTROL OVER OUR COMPANY
    
 
   
     Ross Perot, our Chairman, President, and Chief Executive Officer, is the
managing general partner of HWGA, Ltd., a partnership that owned 15,852,500
shares of our Class A Common Stock as of September 30, 1998. Accordingly, upon
completion of the offering, Mr. Perot, through HWGA, Ltd., will control
approximately      % of our outstanding voting common stock. As a result, Mr.
Perot, through HWGA, Ltd., will have the power to block corporate actions such
as an amendment to our Amended and Restated Certificate of Incorporation, the
consummation of any merger, or the sale of all or substantially all of our
assets. In addition, Mr. Perot may significantly influence the election of
directors and any other action requiring shareholder approval. The other general
partner of HWGA, Ltd. is Ross Perot, Jr., a director of our company, who has the
authority to manage the partnership and direct the voting or sale of the shares
of Class A Common Stock held by HWGA, Ltd. if Ross Perot is no longer the
managing general partner.
    
 
LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS
 
     Our success depends largely on the skills, experience, and performance of
some key members of our management, including our Chairman, President, and Chief
Executive Officer, Ross Perot. The loss of any key
                                        8
<PAGE>   11
 
members of our management may materially and adversely affect our business,
financial condition, and results of operations.
 
OUR CONTRACTS CONTAIN TERMINATION PROVISIONS AND PRICING RISKS
 
   
     Many of the services we provide are critical to our clients' business. Some
of our contracts with clients permit termination in the event our performance is
not consistent with service levels specified in those contracts. The ability of
our clients to terminate contracts creates an uncertain revenue stream. If
clients are not satisfied with our level of performance, our reputation in the
industry may suffer, which may also materially and adversely affect our
business, financial condition, and results of operations.
    
 
     Some of our contracts contain pricing provisions that require the payment
of a set fee by the client for our services regardless of the costs we incur in
performing these services, or provide for penalties in the event we fail to
achieve certain contract milestones. In such situations, we are exposed to the
risk that we will incur significant unforeseen costs or such penalties in
performing the contract.
 
FAILURE TO PROPERLY MANAGE GROWTH COULD ADVERSELY AFFECT OUR BUSINESS
 
     We have expanded our operations rapidly in recent years. We intend to
continue expansion in the foreseeable future to pursue existing and potential
market opportunities. This rapid growth places a significant demand on
management and operational resources. In order to manage growth effectively, we
must implement and improve our operational systems, procedures, and controls on
a timely basis. If we fail to implement these systems, our business, financial
condition, and results of operations will be materially and adversely affected.
 
SIGNIFICANT UNALLOCATED NET PROCEEDS
 
     We have not designated any specific uses for the net proceeds of this
offering. Therefore, we will have broad discretion in how we use such net
proceeds, which may include working capital, business expansion, and other
general corporate purposes.
 
WE OPERATE IN HIGHLY COMPETITIVE MARKETS
 
     Our markets are intensely competitive. Our customers' requirements and the
technology available to satisfy those requirements continually change.
 
     Our principal competitors include Andersen Consulting LLP, Cambridge
Technology Partners, Inc., Cap Gemini Group, Computer Sciences Corporation,
debis Systemhaus GmbH (the information technology division of Daimler-Benz AG),
Electronic Data Systems Corporation, Ernst & Young LLP, IBM Global Services (a
division of International Business Machines Corporation), KPMG Peat Marwick LLP,
MCI Systemhouse, Oracle Corporation, PricewaterhouseCoopers LLP, and The SABRE
Group Holdings, Inc.
 
     Many of these companies, as well as some other competitors, have greater
financial resources and a larger customer base than we do and may have larger
technical, sales, and marketing resources than we do. We expect to encounter
additional competition as we address new markets and as the computing and
communications markets converge.
 
     We must frequently compete with a client's own internal information
technology capability, which may constitute a fixed cost for the client. This
may increase pricing pressure on us. If we are forced to lower our pricing or if
demand for our services decreases, our business, financial condition, and
results of operations will be materially and adversely affected.
 
     We compete on the basis of a number of factors, including the
attractiveness of the business strategy and services that we offer, breadth of
services we offer, pricing, technological innovation, quality of service, and
ability to invest in or acquire assets of potential customers. Some of these
factors are outside our control. We cannot be sure that we will compete
successfully against our competitors in the future. If we fail to compete
successfully against our current or future competitors with respect to these or
other factors, our business, financial condition, and results of operations will
be materially and adversely affected.

<PAGE>   12
 
VARIABILITY OF QUARTERLY OPERATING RESULTS
 
     We expect our revenues and operating results to vary from quarter to
quarter. Such variations are likely to be caused by many factors that are, to
some extent, outside our control, including:
 
     - mix and timing of client projects;
 
   
     - completing client projects;
    
 
   
     - hiring, integrating, and utilizing associates; and
    
 
     - timing of new contracts.
 
Accordingly, we believe that quarter-to-quarter comparisons of operating results
for preceding quarters are not necessarily meaningful. You should not rely on
the results of one quarter as an indication of our future performance.
 
CHANGES IN TECHNOLOGY COULD ADVERSELY AFFECT OUR BUSINESS
 
     The markets for our information technology services change rapidly because
of technological innovation, new product introductions, changes in customer
requirements, declining prices, and evolving industry standards, among other
factors. New products and new technology often render existing information
services or technology infrastructure obsolete, excessively costly, or otherwise
unmarketable. As a result, our success depends on our ability to timely innovate
and integrate new technologies into our service offerings. We cannot guarantee
that we will be successful at adopting and integrating new technologies into our
service offerings in a timely manner.
 
     Advances in technology also require us to commit substantial resources to
acquiring and deploying new technologies for use in our operations. We must
continue to commit resources to train our personnel and our clients' personnel
in the use of these new technologies. We must continue to train personnel to
maintain the compatibility of existing hardware and software systems with these
new technologies. We cannot be sure that we will be able to continue to commit
the resources necessary to refresh our technology infrastructure at the rate
demanded by our markets.
 
   
INTELLECTUAL PROPERTY RIGHTS
    
 
     In recent years, there has been significant litigation in the United States
involving patent and other intellectual property rights. We are not currently
involved in any such litigation. We may, however, be a party to such litigation
in the future to protect our trade secrets or know-how.
 
     Our suppliers, clients, and competitors may have patents and other
proprietary rights that cover technology employed by us. Such persons may also
seek patents in the future. United States patent applications are confidential
until a patent is issued and most technologies are developed in secret.
Accordingly, we are not, and cannot, be aware of all patents or other
intellectual property rights of which our services may pose a risk of
infringement. Others asserting rights against us could force us to defend
ourselves or our clients against alleged infringement of intellectual property
rights. We could incur substantial costs to prosecute or defend any such
litigation and intellectual property litigation could force us to do one or more
of the following:
 
     - cease selling or using products or services that incorporate the
       challenged technology;
 
     - obtain from the holder of the infringed intellectual property right a
       license to sell or use the relevant technology; and
 
     - redesign those services or products that incorporate such technology.

PROVISIONS OF OUR CERTIFICATE OF INCORPORATION, BYLAWS, AND DELAWARE LAW COULD
DETER TAKEOVER ATTEMPTS
 
     Our Board of Directors may issue up to 5,000,000 shares of Preferred Stock
and may determine the price, rights, preferences, privileges, and restrictions,
including voting and conversion rights, of these shares of Preferred Stock.
These determinations may be made without any further vote or action by our
stockholders. The rights of the holders of Common Stock will be subject to, and
may be adversely affected by, the rights of the holders of any Preferred Stock
that may be issued in the future. The issuance of Preferred Stock may make it
more difficult for a third party to acquire a majority of our outstanding voting
stock.
 
   
     In addition, we intend to adopt a stockholders' rights plan. Under this
plan, after the occurrence of specified events that may result in a change of
control, our stockholders will be able to buy stock from us or our successor at
half the then current market price. These rights will not extend, however, to
persons participating in takeover attempts without the consent of our Board of
Directors. Accordingly, this plan could deter takeover attempts. See
"Description of Capital Stock -- Provisions Relating to Change in Control --
Stockholder Rights Plan."
    
 
   
     Some provisions of our Amended and Restated Certificate of Incorporation
and Bylaws and of Delaware General Corporation Law could also delay, prevent, or
make more difficult a merger, tender offer, or proxy contest involving our
company. See "Description of Capital Stock." Among other things, these
provisions:
    
 
   
     - require an 80% vote of the stockholders to amend our Bylaws;
    
 
     - require advance notice for stockholder proposals and director nominations
       to be considered at a vote of a meeting of stockholders;
 
     - permit only our Chairman, President, or a majority of our Board of
       Directors to call stockholder meetings, unless our Board of Directors
       otherwise approves;
 
     - prohibit actions by stockholders without a meeting, unless our Board of
       Directors otherwise approves; and
 
     - limit transactions between our company and persons that acquire
       significant amounts of stock without approval of our Board of Directors.
 
NO DIVIDENDS
 
     We have never declared or paid a cash dividend on our Common Stock. We do
not anticipate paying any cash dividends on our Common Stock in the foreseeable
future.
 
RISKS RELATED TO INTERNATIONAL OPERATIONS
 
   
     We have operations in many countries around the world. Risks that affect
international operations include:
    
 
     - fluctuations in currency exchange rates;
 
     - complicated licensing and work permit requirements;
 
     - variations in the protection of intellectual property rights;
 
     - restrictions on the ability to convert currency; and
 
     - additional expenses and risks inherent in conducting operations in
       geographically distant locations, with customers speaking different
       languages and having different cultural approaches to the conduct of
       business.
 
   
To attempt to mitigate the effects of foreign currency fluctuations on the
results of our foreign operations, we sometimes use forward exchange contracts
and other hedging techniques to help protect us from large swings in currency
exchange rates.

ABSENCE OF PRIOR PUBLIC MARKET OF COMMON STOCK CREATES UNCERTAINTY IN MARKET
PRICE
 
     Prior to this offering, you could not buy or sell our Common Stock
publicly. An active public market for the Class A Common Stock may not develop
or be sustained after the offering. We negotiated and determined the initial
public offering price with the representatives of the Underwriters based on
several factors. This price may vary from the market price of the Class A Common
Stock after the offering. See "Underwriters." The market price of the Class A
Common Stock may fluctuate significantly in response to a number of factors,
some of which are beyond our control, including:
 
     - quarterly variations in operating results;
 
     - changes in financial estimates by securities analysts;
 
     - changes in market valuations of information technology service and
       solution companies;
 
     - announcements by us of significant contracts, acquisitions, strategic
       partnerships, joint ventures, or capital commitments;
 
     - loss of a major client;
 
     - additions or departures of key personnel; and
 
     - sales of Class A Common Stock.
 
     In addition, the stock market experiences significant price and volume
fluctuations, which may materially and adversely affect the market price of the
Class A Common Stock.
 
AVAILABILITY OF SIGNIFICANT AMOUNTS OF CLASS A COMMON STOCK FOR SALE COULD
ADVERSELY AFFECT ITS MARKET PRICE
 
   
                    shares of Class A Common Stock and 467,160 shares of Class B
Common Stock will be outstanding after consummation of this offering. The
          shares of Class A Common Stock being offered hereby will be eligible
for immediate resale in the public market without restriction, unless we or one
of our affiliates acquire any such shares.
    
 
   
     Following the offering, there will be approximately           additional
shares of Class A Common Stock outstanding or subject to currently exercisable
options. We believe that substantially all of these shares of Class A Common
Stock, and shares of Class A Common Stock issuable upon the exercise of such
options, will be freely tradable under Federal securities laws following this
offering, subject to some limitations. These limitations include vesting
provisions in option and restricted stock agreements, restrictions in lock-up
agreements, and volume and manner-of-sale restrictions under Rule 144. In
addition, UBS holds immediately exercisable options to purchase 3,200,000 shares
of our Class B Common Stock, of which 276,632 options could be exercised and
sold without restriction under Federal securities laws following the offering.
In addition, UBS holds 426,326 shares of Class B Common Stock that may be sold
without restriction under Federal Securities laws following the offering. The
future sale of a substantial number of shares of Common Stock in the public
market following this offering, or the perception that such sales could occur,
could adversely affect the prevailing market price.
    
 
   
     We have issued a substantial number of options to purchase shares of Class
A Common Stock to our associates prior to this offering. Following this
offering, we expect to continue to issue options to our associates to reward
performance and encourage retention. The exercise of any additional options
issued by us could adversely affect the prevailing market price of the Class A
Common Stock.
    
 
     Stockholders holding more than   % of the outstanding Common Stock and
currently exercisable options to purchase Common Stock have executed lock-up
agreements that limit their ability to sell Common Stock. These stockholders
have agreed not to sell or otherwise dispose of any shares of Common Stock for a
period of at least 180 days after the date of this Prospectus without the prior
written approval of Morgan Stanley & Co. Incorporated and us. Morgan Stanley &
Co. Incorporated and we may, in our sole discretion and at any time without
notice, release all of any portion of the securities subject to lock-up
agreements. See "Shares Eligible for Future Sale."

RISKS RELATED TO POTENTIAL YEAR 2000 PROBLEMS MAY ADVERSELY AFFECT OUR BUSINESS
 
     Some computers, software, and other equipment include computer code in
which calendar year data is abbreviated to only two digits. As a result, some of
these systems could fail to operate or fail to produce correct results because
they may interpret "00" to mean 1900, rather than 2000 -- widely known as the
"Year 2000 Problem." These problems are likely to increase in frequency and
severity as the year 2000 approaches. The Year 2000 Problem affects some of our
computers, software, and other equipment. If we fail to properly recognize and
address the Year 2000 Problem in our systems, our business, financial condition,
and results of operations could be materially and adversely affected.
 
     Some of our clients will be affected by the Year 2000 Problem. In some
situations, we agreed to modify, upgrade, or replace our clients' systems. We
have estimated our costs to perform these services and included these costs in
our existing contracts, although we cannot guarantee that our estimates are
accurate. If we fail to adequately assess such costs, our business, financial
condition, and results of operations could be materially and adversely affected.
 
     The Year 2000 Problem also affects some of our major suppliers of
computers, software, and other equipment. We have discussed the Year 2000
Problem with some of these suppliers, but we cannot guarantee that these
suppliers will resolve any or all Year 2000 Problems. If our suppliers fail to
resolve Year 2000 Problems, our business could be materially disrupted.
 
   
     We expect to identify and resolve all Year 2000 Problems that could
materially adversely affect our business operations. However, our management
believes that it is not possible to determine with complete certainty that all
Year 2000 Problems affecting us or our clients have been identified or
corrected. The number of devices that could be affected and the interactions
among these devices are simply too numerous. In addition, no one can accurately
predict how many Year 2000 Problem-related failures will occur or the severity,
duration, or financial consequences of these perhaps inevitable failures. As a
result, our management believes that the following consequences are possible:
    
 
   
     - a significant number of operational inconveniences and inefficiencies for
       us and our clients that will divert management's time and attention and
       financial and human resources from its ordinary business activities;
    
 
   
     - a lesser number of serious system failures that will require significant
       efforts by us or our clients to prevent or alleviate material business
       disruptions;
    
 
   
     - several routine business disputes and claims for pricing adjustments or
       penalties due to Year 2000 Problems by our clients, which will be
       resolved in the ordinary course of business; and
    
 
   
     - a few serious business disputes alleging that we failed to comply with
       the terms of its contracts or industry standards of performance, some of
       which could result in litigation or contract termination.
    
 
     See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Year 2000 Issues."
 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
     Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business," and elsewhere in this Prospectus constitute
forward-looking statements. These statements involve known and unknown risks,
uncertainties, and other factors that may cause our or our industry's actual
results, levels of activity, performance, or achievements to be materially
different from any future results, levels of activity, performance, or
achievements expressed or implied by such forward-looking statements. Such
factors include, among others, those listed under "Risk Factors" and elsewhere
in this Prospectus.

     In some cases, you can identify forward-looking statements by terminology
such as "may," "will," "should," "expects," "plans," "anticipates," "believes,"
"estimates," "predicts," "potential," or "continue" or the negative of such
terms or other comparable terminology.
 
     Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance, or achievements.
 
     Moreover, neither we nor any other person assumes responsibility for the
accuracy and completeness of such statements. We are under no duty to update any
of the forward-looking statements after the date of this Prospectus to conform
such statements to actual results.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of shares of Class A Common
Stock in this offering are estimated to be $     million ($     million if the
Underwriters exercise their over-allotment option in full), after deducting
underwriting discounts and commissions and estimated offering expenses of
$          payable by the Company. The principal purposes of this offering are
to create a public market for the Class A Common Stock, which will facilitate
future access by the Company to public equity markets and enhance the ability of
the Company to use its Class A Common Stock as a means for attracting and
retaining key employees, and to obtain additional capital. The Company expects
to use the net proceeds from the offering primarily for working capital,
business expansion, and other general corporate purposes. The Company will have
significant discretion in the use of the net proceeds of this offering.
 
                                DIVIDEND POLICY
 
   
     The Company has never declared or paid a cash dividend on the Common Stock.
The Company currently does not anticipate paying any cash dividends in the
foreseeable future. Any future determination to pay dividends will be at the
discretion of the Company's Board of Directors and will be dependent upon then
existing conditions, including the Company's financial condition, results of
operations, contractual restrictions, capital requirements, business prospects,
and such other factors as the Company's Board of Directors deems relevant.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
   
     The following selected consolidated financial data as of and for the years
ended December 31, 1997, 1996, 1995, 1994, and 1993 have been derived from the
Company's Consolidated Financial Statements, which have been audited by
PricewaterhouseCoopers LLP, independent auditors. The selected consolidated
financial information as of and for the nine months ended September 30, 1998 and
1997 have been derived from unaudited consolidated financial statements, which,
in management's opinion, reflect all adjustments (consisting of only normal and
recurring accruals) necessary to present fairly the Company's financial position
and results of operations for those periods. Interim results are not necessarily
indicative of the results that may be expected for any other interim period or
for the full year. This information should be read in conjunction with

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following commentary should be read in conjunction with the
Consolidated Financial Statements and the Related Notes contained elsewhere in
this Prospectus.
    
 
OVERVIEW
 
   
     The Company is a worldwide provider of information technology services and
business solutions to a broad range of clients. The Company integrates three
core disciplines in providing solutions and services to its clients: information
technology infrastructure services, systems integration and applications
development, and business integration. Information technology infrastructure
services combine information technology outsourcing, staffing, and
infrastructure management. Systems integration and applications development
include implementation of new and existing systems, including both
custom-developed and packaged software. Business integration services include
working with clients to develop and implement business strategy, information
technology strategy, process redesign, and change management.
    
 
   
     From 1993 through the first nine months of 1998, the Company's business mix
shifted from being predominantly an information technology infrastructure
services provider, where revenue was obtained through long-term unit-price or
fixed-price facilities management contracts, to a more balanced mix with
increased emphasis on systems integration and applications development and
business integration. Information technology infrastructure services currently
make up less than half of the Company's revenue, and newer engagements are
primarily level-of-effort based contracts that combine several service
offerings. The Company's strategy is to continue this increased focus on systems
integration and applications development and business integration services,
supported by value-added information technology infrastructure services.
    
 
   
     During 1996 and 1997, the Company made several acquisitions. The acquired
firms added strength in the areas of business integration and consulting,
business-to-business electronic commerce over the Internet, business
reengineering, object-oriented applications development, data mining, and
systems management. These acquisitions contributed revenue of $62.0 million for
the nine months ended September 30, 1998.
    
 
   
     The Company's top ten clients accounted for approximately 65.4% of total
revenue for the nine months ended September 30, 1998, 64.1% for the year ended
December 31, 1997, and 68.3% for the year ended December 31, 1996. See "Risk
Factors -- Loss of Major Clients Could Adversely Affect Our Business."
Approximately 35.4% of the Company's total revenue was derived from
international operations for the nine months ended September 30, 1998, 33.6% for
the year ended December 31, 1997, and 33.2% for the year ended December 31,
1996.
    
 
   
     The Company provides services under contracts containing pricing provisions
that relate to the level of services supplied by the Company
("level-of-effort"), provide for a set fee to be received by the Company
("fixed-price"), or link the revenue to the Company to a client-specific data
point, such as the number of transactions processed or CPU minutes consumed
("unit-price"). Many of the Company's contracts combine more than are of these
types of provisions. The majority of revenue for the nine months ended September
30, 1998 and year ended December 31, 1997 was derived from level-of-efforts
pricing. Revenue from level-of-efforts pricing is based on time and materials,
direct costs plus an administrative fee (which may be either a fixed amount or a
percentage of direct costs incurred), or a combination of these methods and may
be based on a set fee for a specified level of resources that is adjusted for
incremental resource usage. Revenue from fixed-price contracts is recognized on
the percentage-of-completion method, and is earned based on the percentage
relationship of incurred contract costs to date to total estimated contract
costs, after giving effect to the most recent estimates of total cost. Revenue
from unit-price contracts is recognized based on technology units utilized or by
number of transactions processed during a given period. For unit-price
contracts, the Company establishes a per-unit fee based on the cost structure
associated with the delivery of that unit of service.
    
 
   
     Year 2000 engagements do not comprise a substantial portion of the
Company's business. For two Year 2000 projects, the Company uses a zero estimate
of profit with equal amounts of revenue and cost
    
 
                                       17
<PAGE>   20
 
   
recognized until the final outcome of the engagement can be estimated more
precisely because of the inherent uncertainties regarding testability in the
existing system environment and client acceptance.
    
 
     The Company continuously monitors its contract performance in light of
client expectations, the complexity of work, project plans, delivery schedules,
and other relevant factors. Provisions for estimated losses, if any, are made in
the period in which the loss first becomes probable and reasonably estimable.
Other contract-related accrued liabilities are also recorded to match
contract-related expenses in the period in which revenues from those contracts
are recognized.
 
   
     The Company experienced substantial growth in 1996, 1997, and during the
first nine months of 1998. A significant portion of the growth in 1996 resulted
from the Company's entry into the UBS Agreements in January 1996. The Company's
operating UBS relationship comprises two main components, the IT Services
Agreement, which is a level-of-effort contract, and various project assignments.
See "Business -- UBS Agreements." During the years ended December 31, 1997 and
1996, approximately 21.7% and 22.9%, respectively, of the Company's revenues
were earned in connection with services performed under the IT Services
Agreement, and 5.5% and 5.3%, respectively, of the Company's revenues were
earned in connection with the various projects performed for UBS. For the nine
month period ended September 30, 1998, approximately 22.1% of the Company's
revenues were earned in connection with services performed under the IT Services
Agreement and approximately 3.3% of the Company's revenues were earned in
connection with other services performed for UBS.
    
 
   
     The Company has increased its focus on expense reduction and cost control
over the last year in numerous ways. The most significant savings in
administrative expenses included reductions in executive compensation expense,
the cancellation of discretionary projects, and reductions in marketing and
promotional expenses, and non-essential travel. In addition, the Company
established more stringent expense policies and created a capital expenditures
review committee. These cost control measures contributed to a decrease in
selling, general and administrative expenses as a percentage of revenue from
16.1% in 1997 to 14.2% for the nine months ended September 30, 1998. The Company
anticipates that expansion in the areas of recruiting, training, and business
development will increase during the remainder of 1998. As a result, the Company
expects selling, general and administrative expenses as a percentage of revenue
will increase from their current level.
    
 
RESULTS OF OPERATIONS
 
   
  Comparison of the nine months ended September 30, 1998 and 1997
    
 
   
     Revenue increased in the nine months ended September 30, 1998 by 30.0% to
$724.2 million from $556.9 million in the nine months ended September 30, 1997,
due to the entry into two significant contracts in the third quarter of 1997
that generated a $63.8 million increase in revenue, $15.8 million in additional
revenue resulting from the inclusion of businesses acquired in the first nine
months of 1997 for the entire nine month period in 1998, and a $87.7 million
increase in revenue from other new and existing business, including $31.2
million from EME and $24.7 million from UBS.
    
 
   
     Domestic revenue grew by 27.2% in the nine months ended September 30, 1998
to $468.0 million from $368.0 million in the nine months ended September 30,
1997, and decreased slightly as a percentage of total revenue to 64.6% from
66.1% over the same period.
    
 
   
     Non-domestic revenue, comprising European and Asian operations, grew by
35.6% in the nine months ended September 30, 1998 to $256.2 million from $188.9
million in the nine months ended September 30, 1997, and increased as a
percentage of total revenue to 35.4% from 33.9%. Asian operations represented
$11.4 million, or 1.6%, and $7.0 million, or 1.3%, of total revenue for the nine
months ended September 30, 1998 and 1997, respectively.
    
 
   
     Direct cost of services increased in the nine months ended September 30,
1998 by 31.4% to $575.1 million from $437.7 million in the nine months ended
September 30, 1997, due primarily to continued growth in the Company's business.
Gross margin decreased slightly to 20.6% from 21.4% for the nine months
    
 
                                       18
<PAGE>   21
 
   
endedSeptember 30, 1998 compared to the nine months ended September 30, 1997,
due primarily to a $13.5 million charge to address Year 2000 exposures for
certain client contracts, without which gross margin would have increased.
    
 
   
     Selling, general and administrative expenses increased in the nine months
ended September 30, 1998 by 7.5% to $103.1 million from $95.9 million in the
nine months ended September 30, 1997, but decreased as a percentage of total
contract revenue to 14.2% from 17.2%, respectively. The most significant savings
in administrative expenses included reductions in executive compensation, the
cancellation of discretionary projects, and reductions in marketing and
promotional expenses, and non-essential travel. Operating income increased in
the nine months ended September 30, 1998 to $42.2 million from $21.3 million in
the nine months ended September 30, 1997, and operating margin (operating income
as a percentage of contract revenue) increased to 5.8% from 3.8%.
    
 
   
     Equity in earnings of unconsolidated affiliates, net, increased in the nine
months ended September 30, 1998 to $4.2 million from $0.7 million during the
nine months ended September 30, 1997 due to improved results at Systor AG
("Systor"), a subsidiary of UBS, and at HCL Perot Systems NV ("HPS"), a software
joint venture based in India. The equity in earnings for Systor increased to
$2.2 million from $0.7 million and equity in earnings for HPS increased to $2.0
million from $0.1 million during the nine months ended September 30, 1998 and
1997, respectively. Other income/(expense) increased in the nine months ended
September 30, 1998 to $2.7 million from $1.3 million in the nine months ended
September 30, 1997 primarily due to a $3.0 million gain on the sale of the
Company's limited partnership interest in a venture capital fund in 1998, offset
in part by a $0.8 million decrease in foreign exchange gains from 1997 to 1998.
    
 
   
     The increase in the effective tax rate to 45.7% for the nine months ended
September 30, 1998 from 42.5% for the nine months ended September 30, 1997 was
due to a non-deductible goodwill write-down recorded in the third quarter of
1998. Excluding the write-down, the effective rate would have been 42.5%.
    
 
   
     Net income increased 107.4% in the nine months ended September 30, 1998 to
$28.2 million from $13.6 million in the nine months ended September 30, 1997 and
net income margin increased to 3.9% from 2.4%.
    
 
  Comparison of the year ended December 31, 1997 to the year ended December 31,
1996
 
     Revenue increased in 1997 by 30.4% to $781.6 million from $599.4 million in
1996, due to $43.6 million in revenue growth from the UBS Agreements, $60.2
million in revenue representing the inclusion of a full year's results from
certain businesses acquired in the second half of 1996 and revenue received from
businesses acquired during the first half of 1997, and a $78.4 million increase
in revenue from other new and existing contracts.
 
     Domestic revenue grew by 29.7% in 1997 to $519.1 million from $400.2
million in 1996, and decreased slightly as a percentage of total revenue to
66.4% from 66.8% over the same periods.
 
     Non-domestic revenue, consisting of European and Asian operations, grew by
31.8% in 1997 to $262.5 million from $199.2 million in 1996, and increased
slightly as a percentage of total revenue to 33.6%, from 33.2% over the same
periods. Asian operations represented $9.7 million, or 1.2%, and $7.3 million,
or 1.2%, of total revenue in 1997 and 1996, respectively.
 
     Direct cost of services increased in 1997 by 38.0% to $636.3 million from
$461.2 million in 1996. Gross margin decreased to 18.6% in 1997 as compared to
23.1% in 1996. The decrease in gross margin was due in part to a margin decline
from 1996 to 1997 related to the renegotiation of the UBS Agreements, which took
effect on January 1, 1997. The Company also incurred expenses of $4.3 million in
1997 resulting from an expansion of business integration activities. In
addition, the Company incurred several special charges in 1997, including
special contract loss provisions of $10.2 million related to known termination
and contract completion losses on two long-term contracts, a $3.6 million
write-off of intellectual property rights acquired, and a $3.1 million charge
related to the abandonment and sub-lease of unused office space, collectively
resulting in a 2.7% increase in direct cost of services.
 
                                       19
<PAGE>   22
 
   
     Selling, general and administrative expenses increased in 1997 to 16.1% of
total revenue from 15.5% of total revenue in 1996, due primarily to expansion of
the sales force, staff growth in management and administrative support areas,
severance for senior executives and increased goodwill amortization associated
with businesses acquired. As a result of the factors noted above, operating
income decreased in 1997 to $17.6 million from $41.3 million in 1996, and
operating margin declined to 2.3% from 6.9%.
    
 
     Equity in earnings of unconsolidated affiliates, net, increased in 1997 to
$4.1 million from a loss of $0.3 million in 1996 due to improved results at
Systor and HPS. The equity in earnings for Systor increased to $3.6 million from
$0.9 million and the equity in earnings of HPS increased to $0.5 million from a
loss of $1.2 million in 1997 and 1996, respectively. Other income, net,
increased in 1997 to $1.1 million from a net expense of $1.6 million in 1996.
The positive impact of the above items was substantially offset by a $3.9
million write down of non-marketable equity securities to net realizable value
during 1997.
 
     The decrease in the effective tax rate to 42.5% in 1997 from 48.9% in 1996
was due to both a decrease in nondeductible amortization related to acquisitions
and increased earnings in foreign jurisdictions in which the Company intends to
permanently invest subsidiary profits.
 
     Net income decreased 45.4% in 1997 to $11.2 million from $20.5 million in
1996 and net income margin decreased to 1.4% from 3.4%.
 
     Prior to special charges, which included special contract loss provisions,
the write-off of purchased research and development, the write-off of acquired
intellectual property rights, and the write-down of non-marketable equity
securities, income before taxes decreased to $39.2 million in 1997 from $44.1
million in 1996. Net income, excluding the after tax effect of these charges,
increased to $22.6 million in 1997 from $22.5 million in 1996.
 
  Comparison of the year ended December 31, 1996 to the year ended December 31,
1995
 
     Revenue increased in 1996 by 75.1% to $599.4 million from $342.3 million in
1995, due to $161.5 million in revenue from the UBS Agreements, $10.7 million in
revenue from businesses acquired in the second half of 1996, and a $84.9 million
increase in revenue from other new and existing business.
 
     Domestic revenue grew by 67.6% in 1996 to $400.2 million from $238.8
million in 1995, but declined as a percentage of total revenue to 66.8% from
69.8% over the same periods. UBS accounted for $88.9 million of the domestic
revenue in 1996 compared to $2.8 million in 1995.
 
     Non-domestic revenue, consisting of European and Asian operations, grew by
92.5% in 1996 to $199.2 million from $103.5 million in 1995, and increased as a
percentage of total revenue to 33.2% from 30.2% over the same periods. The key
factor was the UBS revenue of which $72.7 million was earned in Europe and $7.3
million in Asia. Asian operations represented $7.3 million, or 1.2%, of total
revenue in 1996, the first year the Company had operations in Asia.
 
     Direct cost of services increased by 71.7% in 1996 to $461.2 million from
$268.6 million in 1995 and gross margin increased to 23.1% in 1996 from 21.5% in
1995, due primarily to the UBS Agreements entered into in 1996.
 
     Selling, general, and administrative expenses increased in 1996 to 15.5% of
total revenue from 15.4% of total revenue in 1995, due primarily to significant
increases in revenue, offset by the addition of senior executives, expansion of
the sales force, and staff growth in management and administrative support
areas. As a percentage of revenues, selling, general, and administrative
expenses remained essentially unchanged. Operating income increased in 1996 to
$41.3 million from $20.9 million in 1995, reflecting business growth and other
factors discussed above. Operating margin increased in 1996 to 6.9% from 6.1% in
1995, due to a decline in direct costs of services as a percentage of contract
revenue in 1996 to 76.9% from 78.5% in 1995.
 
     The effective tax rate increased in 1996 to 48.9% from 46.6% in 1995, due
primarily to an increase in non-deductible expense items.
 
     Net income increased to $20.5 million in 1996 from $10.8 million in 1995.
Net income margin increased in 1996 to 3.4% from 3.2% in 1995.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     During the nine months ended September 30, 1998, cash and cash equivalents
increased 189.5% to $102.2 million from $35.3 million at December 31, 1997
primarily due to increased cash flow from operating activities.
    
 
   
     Cash flow provided by operating activities increased to $65.1 million from
$15.8 million for the periods ended September 30, 1998 and 1997, respectively.
The increase in cash flow from operating activities was due primarily to the
$93.6 million increase in current liabilities such as accrued liabilities and
accrued compensation, offset in part by a $49.9 million increase in current
assets consisting primarily of increased accounts receivable.
    
 
   
     Net cash used in investing activities was $4.8 million for the nine months
ended September 30, 1998 compared to $56.6 million for the nine months ended
September 30, 1997. Cash expenditures for property, equipment, and software
during the nine months ended September 30, 1998 was $18.9 million and was
partially offset by $7.6 million in proceeds from the sale of property,
equipment and software and the sale of the Company's limited partnership
interest in a venture capital fund for $5.2 million. For the nine months ended
September 30, 1997, there were $33.9 million in cash expenditures for property,
equipment and software, $13.3 million in cash used for business acquisitions and
$6.3 million for the acquisition of intellectual property rights. The
year-on-year decline of 44% in property, equipment and software purchases was
due in part to more rigorous capital expenditure review procedures which were
implemented in the fourth quarter of 1997.
    
 
   
     For the nine months ended September 30, 1998, net cash provided by
financing activities was approximately $4.5 million, compared to $29.6 million
for the nine months ended September 30, 1997. This decrease was due primarily to
the fourth quarter of 1997 repayment of a $25.0 million borrowing on the
Company's line of credit at September 30, 1997. There were no subsequent
borrowings on this line of credit in 1998. In addition, the Company received
proceeds of $8.1 million from the sale of Class B Common Stock options to UBS
during the nine months ended September 30, 1997 and $3.0 million in proceeds
from the exercise of 417,160 of such stock options during the nine months ended
September 30, 1998.
    
 
   
     As of October 31, 1998, the Company had a $40.0 million undrawn line of
credit with a financial institution that expires in January 1999. The Company
anticipates that cash flows from operating activities will provide sufficient
funds to meet its needs for the foreseeable future. From time to time, the
Company may consider repurchasing its Class A Common Stock depending on price
and availability and alternative uses for its financial resources.
    
 
NEW ACCOUNTING DEVELOPMENTS
 
     In June 1997, the Financial Accounting Standard Board ("FASB") issued SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("Statement 131") effective for years beginning after December 15, 1997.
Statement 131 requires that a public company report financial and descriptive
information about its reportable operating segments pursuant to criteria that
differ from current accounting practice. Operating segments, as defined, are
components of an enterprise about which separate financial information is
available that is evaluated regularly by management in deciding how to allocate
resources and in assessing performance. The financial information to be reported
includes segment profit or loss, certain revenue and expense items and segment
assets and reconciliations to corresponding amounts in the financial statements.
Statement 131 also requires information about revenues from products or
services, countries where the company has operations or assets and major
customers. Management does not believe the implementation of Statement 131 will
have a material impact on its consolidated financial statements.
 
     In June 1998, the FASB issued SFAS No. 133 which establishes accounting and
reporting standards for derivative instruments and for hedging activities. The
statement requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet at fair value. If certain conditions are met, a
derivative may be specifically designated as a fair value hedge, a cash flow
hedge, or a foreign currency hedge. A specific accounting treatment applies to
each type of hedge. SFAS No. 133 is effective for all fiscal quarters
 
                                       21
<PAGE>   24
 
   
of fiscal years beginning after June 15, 1999. SFAS No. 133 is not expected to
have a material impact on the Company's financial position or results of
operations.
    
 
   
     The American Institute of Certified Public Accountants (the "AICPA") issued
Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," in March 1998. SOP 98-1
provides guidance on accounting for the costs of computer software developed or
obtained for internal use and requires costs incurred in the application
development stage (whether internal or external) to be capitalized. This SOP is
applicable to all financial statements for fiscal years beginning after December
15, 1998, and should be applied to internal-use computer software costs incurred
in those fiscal years for all projects, including those projects in progress
upon initial application of this SOP. Costs incurred prior to initial
application of this SOP, whether or not capitalized, should not be adjusted to
the amounts that would have been capitalized had this SOP been in effect when
those costs were incurred. The adoption of this SOP is not expected to have a
material impact on the annual financial position or results of operations.
    
 
YEAR 2000 ISSUES
 
   
     The following statements and all other statements made in this Prospectus
or the accompanying consolidated financial statements with respect to the
Company's Year 2000 processing capabilities or readiness are "Year 2000
Readiness Disclosures" in conformance with the Year 2000 Information and
Readiness Disclosure Act of 1998 (Public Law 105-271, 112 Stat. 2386).
    
 
   
     Some computers, software, and other equipment includes computer code in
which calendar year data is abbreviated to only two digits. As a result of this
design decision, some of these systems could fail to operate or fail to produce
correct results if "00" is interpreted to mean 1900, rather than 2000. These
problems are widely expected to increase in frequency and severity as the year
2000 approaches, and are commonly referred to as the "Year 2000 Problem".
    
 
   
     Assessment. The Year 2000 Problem affects computers, software, and other
equipment used, operated, or maintained by the Company for itself and its
customers. Accordingly, the Company has organized a program team responsible for
monitoring the assessment and remediation status of the Company's Year 2000
projects and reporting such status to the Company's Board of Directors. This
project team is currently assessing the potential impact of, and costs of
remediating, the Year 2000 Problem for its internal systems and, where the
Company is contractually obligated to remediate the Year 2000 Problem, on
systems operated or maintained on behalf of its customers. In addition, the
Company is performing Year 2000 assessments for some other customers on a
project by project basis.
    
 
   
     For reporting purposes, the Company is using a methodology involving the
following six phases: Discovery, Assessment, Planning, Remediation, Testing, and
Implementation. At September 30, 1998, the discovery and assessment phases were
substantially complete for most program areas. The target completion dates for
priority items by remaining steps are as follows: Discovery -- December 1998;
Assessment -- December 1998; Planning -- December 1998; Remediation -- September
1999; Testing -- September 1999; and Implementation -- September 1999.
    
 
   
     Because the Company's business involves the assessment, implementation, and
operation of computer systems, the Company has not generally obtained
verification or validation by independent third parties of its processes to
assess Year 2000 Problems, its corrections of Year 2000 Problems, or the costs
associated with these activities. However, the Company's Year 2000 project team
is reviewing the project plans prepared by each of the Company's business units
and monitoring their methods and progress against those plans.
    
 
   
     Internal Infrastructure. The Company believes that it has identified most
of the major computers, software applications, and related equipment used in
connection with its internal operations that must be modified, upgraded, or
replaced to minimize the possibility of a material disruption to its business.
The Company has commenced the process of modifying, upgrading, and replacing
major systems that have been assessed as adversely affected, and expects to
complete this process before the occurrence of any material disruption of its
business.
    
 
                                       22
<PAGE>   25
 
   
     Systems Other than Information Technology Systems. In addition to computers
and related systems, the operation of office and facilities equipment, such as
fax machines, photocopiers, telephone switches, security systems, elevators, and
other common devices may be affected by the Year 2000 Problem. The Company is
currently assessing the potential effect of, and costs of remediating, the Year
2000 Problem on its office and facilities equipment.
    
 
   
     The Company estimates the total cost to the Company of completing any
required modifications, upgrades, or replacements of these internal systems to
be approximately $1.0 million, almost all of which the Company believes will be
incurred during the remainder of 1998 and 1999. This estimate is being monitored
and will be revised as additional information becomes available. In addition,
the Company recorded a $13.5 million charge in direct cost of services for the
nine months ended September 30, 1998 to address Year 2000 expenses for certain
client contracts.
    
 
   
     Based on the activities described above, the Company does not believe that
the Year 2000 Problem will have a material adverse effect on the Company's
business or results of operations. In addition, the Company has not deferred any
material information technology projects as a result of its Year 2000 Problem
Activities.
    
 
   
     Client Systems. During 1997, the Company initiated assessments of the
effect of the Year 2000 Problem on computers, software, and other equipment it
operates or maintains for its customers, and its obligations to modify, upgrade,
or replace these systems. As part of this process, the Company has been
estimating the costs and revenues to the Company for performing any necessary
services. The Company is monitoring and updating this assessment on an ongoing
basis. The estimated cost associated with making clients' systems Year 2000
compliant for contracts where the Company is obligated to perform these services
at its expense generally has been and will be treated as a contract cost and is
included in the estimate of total contract costs for the respective contract
under the Company's revenue recognition policy. The Company believes that its
clients have been deferring other projects pending resolution of their Year 2000
Problems.
    
 
   
     Suppliers. The Company has initiated communications with third party
suppliers of the major computers, software, and other equipment used, operated,
or maintained by the Company for itself or its customers to identify and, to the
extent possible, to resolve issues involving the Year 2000 Problem. However, the
Company has limited or no control over the actions of these third party
suppliers. Thus, while the Company expects that it will be able to resolve any
significant Year 2000 Problems with these systems, there can be no assurance
that these suppliers will resolve any or all Year 2000 Problems with these
systems before the occurrence of a material disruption to the business of the
Company or any of its customers. Any failure of these third parties to timely
resolve Year 2000 Problems with their systems could have a material adverse
effect on the Company's business, financial condition, and results of operation.
    
 
   
     Most Likely Consequences of Year 2000 Problems. The Company expects to
identify and resolve all Year 2000 Problems that could materially adversely
affect its business operations. However, management believes that it is not
possible to determine with complete certainty that all Year 2000 Problems
affecting the Company or its clients have been identified or corrected. The
number of devices that could be affected and the interactions among these
devices are simply too numerous. In addition, no one can accurately predict how
many Year 2000 Problem-related failures will occur or the severity, duration, or
financial consequences of these perhaps inevitable failures. As a result,
management believes that the following consequences are possible:
    
 
   
     - a significant number of operational inconveniences and inefficiencies for
       the Company and its clients that will divert management's time and
       attention and financial and human resources from its ordinary business
       activities;
    
 
   
     - a lesser number of serious system failures that will require significant
       efforts by the Company or its clients to prevent or alleviate material
       business disruptions;
    
 
   
     - several routine business disputes and claims for pricing adjustments or
       penalties due to Year 2000 Problems by clients, which will be resolved in
       the ordinary course of business; and
    
 
                                       23
<PAGE>   26
 
   
     - a few serious business disputes alleging that the Company failed to
       comply with the terms of its contracts or industry standards of
       performance, some of which could result in litigation or contract
       termination.
    
 
   
     Contingency Plans. The Company is currently developing contingency plans to
be implemented if its efforts to identify and correct Year 2000 Problems
affecting its internal systems are not effective. The Company expects to
complete its contingency plans by the end of March 1999. Depending on the
systems affected, these plans could include accelerated replacement of affected
equipment or software, short-to medium-term use of backup sites, equipment and
software, increased work hours for Company personnel or use of contract
personnel to correct on an accelerated schedule any Year 2000 Problems that
arise or to provide manual workarounds for information systems, and similar
approaches. If the Company is required to implement any of these contingency
plans, it could have a material adverse effect on the Company's financial
condition and results of operations.
    
 
   
     The Company is also developing contingency plans for certain clients where
such plans are contractually required or are otherwise appropriate to be
developed. In most cases, these contingency plans are being developed jointly by
the Company and its clients. Depending on the systems affected, these plans
could include accelerated replacement of affected equipment or software, short-
to medium-term use of backup sites, equipment and software, increased work hours
for company personnel or use of contract personnel to correct on an accelerated
schedule any Year 2000 Problems that arise or to provide manual workarounds for
information systems, and similar approaches. If the Company is required to
implement any of these contingency plans, it could have a material adverse
effect on the Company's financial condition and results of operations.
    
 
   
     Disclaimer. The discussion of the Company's efforts, and management's
expectations, relating to Year 2000 compliance are forward-looking statements.
The Company's ability to achieve Year 2000 compliance and the level of
incremental costs associated therewith, could be adversely impacted by, among
other things, the availability and cost of programming and testing resources,
vendors' ability to modify proprietary software, and unanticipated problems
identified in the ongoing compliance review.
    
 
   
IMPACT OF EUROPEAN MONETARY UNION
    
 
   
     The European Union is moving towards economic and monetary union in Europe,
with the goal of introducing a single currency called the EURO. The Company is
currently assessing the potential impact of, and costs of adopting, the EURO
conversion for its internal systems and, where the Company is contractually
obligated to take these steps, on systems operated or maintained on behalf of
its customers. For each of these areas, the Company is using the six phase
methodology described above for the Year 2000 Problem. The Company expects to
complete the discovery phase by March 1999, but the EURO conversion is not
expected to have a material impact on the Company's operations or financial
condition or results of operation.
    
 
   
     The discussion of the Company's efforts, and management's expectations,
relating to the EURO conversion are forward-looking statements. The Company's
ability to adapt for the EURO conversion and the level of incremental costs
associated therewith could be adversely impacted by, among other things, the
availability and cost of programming and testing resources and unanticipated
problems identified in the ongoing conversion review.

                                    BUSINESS
 
OVERVIEW
 
     The Company is a worldwide provider of information technology services and
business solutions to a broad range of clients. The Company serves its clients
by delivering services and solutions focused on each client's needs, with
particular emphasis on helping clients more effectively serve their customers.
 
   
     The Company integrates three core disciplines in providing solutions and
services to its clients: (i) business integration; (ii) systems integration and
applications development; and (iii) information technology infrastructure
services. Business integration services include working with clients to develop
and implement business strategy, information technology strategy, process
redesign, and change management. Systems integration and applications
development include the design and implementation of information technology
systems for clients, including both custom-developed and packaged software.
Information technology infrastructure services combine information technology
outsourcing, staffing, and infrastructure management.
    
 
     The Company's approach is to provide clients with an "integrated service
offering" -- a combination of multiple disciplines that assists its clients in
improving their business operations or in creating new business offerings. With
this approach, the Company is able to create long-term relationships with its
clients that begin with an analysis of its clients' business strategies and
continue through the implementation of information technology solutions and the
realization of the clients' goals.
 
   
     In marketing its services, the Company is primarily focused on four
industries: Financial Services, Energy, Healthcare, and Travel and
Transportation. The Company targets these industries to capture the
opportunities arising from their rapid rates of change, growth, and the
increasing importance of information technology in driving and managing this
change and growth. The Company also has significant clients in the
Communications and Media and Manufacturing industries and continually evaluates
additional industries for future growth opportunities. As these opportunities
develop, the Company may allocate resources to target them as additional focal
industries. The Company's clients include: UBS, East Midlands Electricity (IT)
Limited (together with its parent company, East Midlands Electricity plc,
"EME"), National Car Rental System, Inc., Tenet Healthcare Corporation, AT&T
Corp. Volkswagen of America, Inc., Parsons Corporation, and Cedel Global
Services, S.A.
    
 
   
     Ross Perot and eight associates founded the Company in June 1988. Since
then, the Company has grown to over 6,000 associates with operations worldwide
as of September 30, 1998. The Company's revenues have grown from $291.7 million
in 1993 to $781.6 million in 1997 and $724.2 million for the nine months ended
September 30, 1998.
    
 
INDUSTRY BACKGROUND
 
   
     Worldwide demand for information technology services and solutions is
growing at a rapid rate. According to industry sources, the aggregate worldwide
market for business integration, systems integration and applications
development, and information technology infrastructure services was an estimated
$177.9 billion in 1997 and is expected to increase to $307.1 billion in 2002,
representing a compound annual growth rate of 11.5%. These sources also indicate
that the estimated worldwide market size for 1997 and the projected market size
for 2002 for business integration is $46.3 billion and $88.4 billion,
respectively; for systems integration and applications development is $41.6
billion and $76.0 billion, respectively; and for information technology
infrastructure services is $90.0 billion and $142.7 billion, respectively. In
2002, the United States market is expected to account for 51.4% of the global
market with an estimated market size of $158.0 billion, and Western Europe is
expected to account for 27.7% of the global market with an estimated market size
of $85.1 billion.
    
 
     The broad presence of technology in global markets, both in the hands of
businesses and consumers, continually changes the way businesses operate and
compete. Businesses that operate in industries character-
 
                                       25
<PAGE>   28
 
ized by rapid technological change and consolidation, such as Financial
Services, Energy, Healthcare, and Travel and Transportation, must increasingly
rely on information technology to remain competitive.
 
   
     Several factors contribute to growth in the information technology industry
as it transitions from a back office role in business to a key driver in
competitively positioning enterprises, including the rapid pace of technological
change, the globalization and consolidation of industries, and the shift towards
the deregulation of certain industries. Using information technology as a
strategic tool enables enterprises to reduce cycle times and production costs,
improve the rate of introduction of new products, services and pricing, and
better serve the needs of their customers. According to industry experts, the
utilities, transportation, banking and financial services, and communications
sectors are among the industries experiencing the fastest growth in information
technology services expenditures.
    
 
     Designing, developing, and implementing information technology solutions
for individual businesses has become increasingly complex. Many businesses do
not have the time, resources, or expertise to keep pace with industry and
technological change or to efficiently build information technology solutions.
Globally, businesses are increasingly focusing on their core business
competencies and are turning to outside sources to provide information
technology services and skills tailored to create timely solutions and change
business processes to meet specific business objectives.
 
     To date, it has been difficult for businesses to find solutions tailored to
their complex information technology needs. Although there are many suppliers of
information technology solutions, few are able to combine large, integrated
service offerings, global presence, and capital strength with customer focus and
a strong, cohesive culture.
 
THE PEROT SYSTEMS APPROACH
 
   
     The Company provides services on a worldwide basis that are uniquely
structured for each client by combining the appropriate industry expertise and
core disciplines to solve the client's business problems and implement new
strategies to generate future growth. The Company's approach includes:
    
 
     - Providing Integrated Service Offerings. The Company combines its business
       integration, systems integration and applications development, and
       information technology infrastructure services to analyze and address its
       clients' business and information technology challenges and
       opportunities. Rather than narrowly focusing on isolated problems, the
       Company's integrated service offerings are designed to allow a client to
       achieve growth and efficiencies through the implementation of broader
       business solutions.
 
     - Structuring Creative Long-Term Relationships. The Company seeks to create
       long-term relationships with clients that begin with the initial analysis
       of a client's business and information technology problems and
       opportunities and continue through implementation of solutions and the
       realization of benefits. By creatively structuring contracts with
       economic incentives that link the Company's compensation to the client's
       business results or the level of the Company's performance, the Company
       strives to maximize revenues and client satisfaction.
 
   
     - Employing Multi-Disciplinary Teams. The Company employs
       multi-disciplinary teams of associates with industry-specific expertise
       and associates with superior technical skills to best formulate and
       implement integrated information technology solutions for clients.
    
 
     - Formulating Unbiased Client-Based Solutions. The Company analyzes its
       clients' business problems and opportunities from the perspective of the
       clients and their customers. The Company then impartially assembles the
       best combination of Company services and third party products to meet the
       clients' needs.

PEROT SYSTEMS GROWTH STRATEGY
 
     The Company's strategic objective is to become the provider of choice for
information technology services and business solutions. Key elements of the
Company's growth strategy include:
 
     - Expand Value-Added Service Offerings. The Company believes that services
       aimed at growing a client's business and making a client more productive
       and competitive will create more value for the Company's clients, and
       accordingly generate more growth, than traditional technology functional
       services. The Company's strategy includes an increasing focus on systems
       integration and applications development and business integration
       services, supported by value-added information technology infrastructure
       services.
 
     - Target Rapidly Changing Industries. The Company targets rapidly changing
       industries that are substantially affected by the increasing need for
       information technology. The Company utilizes associates with operating
       expertise in these specific industries as a competitive advantage in
       providing superior services to its clients.
 
     - Create and Leverage Growth Engines. In each industry, the Company has the
       opportunity to create "growth engines" -- sets of skills, business
       processes, and know-how that, when combined, create leverageable business
       solutions for clients. The Company can use these growth engines to build
       its presence in its targeted industries and adapt them to develop or
       enter other industries.
 
     - Develop Select Clients. The Company believes that client selection is key
       to growth and profitability. The Company targets market leaders and
       aspiring market leaders that are committed to using information
       technology strategically and are willing to develop long-term
       relationships.
 
   
     - Attract, Train, and Retain Associates with Strong Character. The Company
       believes that attracting, training, and retaining high quality associates
       are essential to its growth. The Company hires motivated individuals with
       strong character and leadership traits and provides them with ongoing
       technological and leadership skills training. The Company emphasizes
       retaining its associates through challenging work assignments and
       incentive programs, including rewarding outstanding performance with
       equity interests in the Company. More than 75% of the Company's
       associates hold equity interests in the Company.
    
 
CORE DISCIPLINES
 
     The Company's broad range of service offerings are classified within three
core disciplines: (i) business integration; (ii) systems integration and
applications development; and (iii) information technology infrastructure
services.
 
                               [Pyramid Graphic]
  [The Prospectus contains a graphic representation of a triangle divided into
        three horizontal segments labeled Business Integration, Systems
      Integration/Applications Development, and Infrastructure Services.]
 
     The Company combines these disciplines into an integrated service offering
to create a customized solution for its clients. The Company believes that, in
addition to providing clients with more comprehensive
 
                                       27
<PAGE>   30
 
information technology and business solutions, its integrated service offerings
allow the Company to attract strategically motivated clients, focus on our
clients' business objectives, and ultimately generate higher value for our
clients.
 
  Business Integration
 
   
     In providing business integration services, the Company works with clients
to, among other things, develop and implement business strategy, information
technology strategy, process redesign, and change management. These services
include:
    
 
     - Business Strategy. To help clients develop and implement business
       strategies, the Company offers strategic advice designed by business and
       technical experts with industry-specific knowledge to align client
       capabilities with the demands of the market in which they compete.
 
     - Information Technology Strategy. The Company helps its clients create and
       implement an information technology strategy that optimizes the use of
       information technology to achieve the client's business objectives. The
       Company employs its extensive knowledge of information technology
       architectures, infrastructures, and technologies to continually refine
       and update its clients' information technology strategies.
 
     - Process Redesign. The Company works with clients to systematically
       reengineer their business processes with innovative approaches
       incorporating cross-industry best practices.
 
     - Change Management. The Company advises clients with respect to major
       business and cultural changes by assessing current skills and resource
       requirements, implementing organizational changes and associated
       measurement systems, and creating employee communication plans.
 
     In order to expand and further develop its business integration
capabilities, the Company has acquired several specialized businesses,
including:
 
   
     Benton International, Inc. Acquired in February 1997, Benton International
is a financial services consulting organization, specializing in telephone and
Internet-based direct banking and electronic payments systems. The firm employs
associates with experience in the financial services industry, including senior
positions at major financial institutions and on governmental advisory boards.
The firm provides strategic business advice to its financial clients, including
advising major retail banks on their mergers and acquisitions strategy.
    
 
  Systems Integration and Applications Development
 
     As part of its systems integration and applications development discipline,
the Company designs and implements information technology systems, including
both custom-developed and packaged software, for clients by offering the
following portfolio of services:
 
     - Systems Integration. The Company assists clients in designing,
       evaluating, and implementing information technology systems comprising
       software applications and hardware components. Services performed by the
       Company range from migrating systems from an existing platform to a new
       platform to installing, configuring, and testing a new system, and
       providing associated training support.
 
     - Applications Development. The Company develops custom software
       applications ranging from modifications and enhancements of existing
       packaged software to completely custom-developed applications. These
       applications are designed for various environments including web-based
       systems, distributed networks, and mainframes.
 
   
     - Project Management. Company associates manage client staff to perform
       systems integration and applications development projects, including
       project scope and change control.
    
 
                                       28
<PAGE>   31
 
     In order to expand and further develop its systems integration and
applications development capabilities, the Company has acquired or established
several specialized business units, including:

     Some recent examples of the Company's relationships with clients in each of
the Company's targeted industries follow.
 
                                       31

  Financial Services
 
     In January 1996, the Company entered into a long-term strategic
relationship with Swiss Bank Corporation. In June 1998, Swiss Bank Corporation
merged with Union Bank of Switzerland to form UBS. As a result, UBS is among the
world's leading financial institutions with assets of approximately $600
billion.
 
     As part of this relationship, the Company assumed responsibility for
management of the information technology infrastructure for Warburg Dillon Read,
the investment banking division of UBS. The Company's activities have included
project management, implementation of two new Warburg Dillon Read trading floors
(in London, England and Stamford, Connecticut), and centrally engineering and
integrating Warburg Dillon Read's workstations globally. The Company is also in
the forefront of integrating information technology infrastructures as UBS
expands, including the integration of such infrastructures with the bank's joint
venture operations. The Company also provides services to UBS's private banking,
commercial banking, and asset management divisions.
 
     As part of its strategic relationship with UBS, the Company received a 40%
equity interest in UBS's Switzerland-based information technology subsidiary,
Systor, and UBS holds an option to purchase shares of the Company's Class B
Common Stock.
 
     The Company's strategic relationship with UBS has enabled it to develop
leading edge expertise in the design, development, and operation of global
trading infrastructures. The Company has utilized, and intends to continue to
utilize, this expertise to attract other client relationships in the financial
services industry on a world-wide basis.
 
  Energy
 
     In 1992, the Company signed a comprehensive, long-term information
technology outsourcing agreement with EME, one of the leading regional electric
companies in the United Kingdom in terms of distribution volume. The Company
assisted EME's reorganization from a consolidated business into separate
operating entities for energy generation, distribution, and supply.
 
     EME's operating environment includes over 75 applications operated across
seven major hardware platforms that utilize 34 programming languages and nine
different databases.
 
     Through project management and the integration of several disparate
computer systems, the Company assisted EME's regulated and non-regulated
businesses in meeting the challenges of the United Kingdom's deregulating energy
sector.
 
     Through its work with EME, the Company has developed an expertise in the
emerging deregulated utility markets. The Company has utilized and intends to
use this expertise and experience as a means to attract other client
relationships, particularly in the United States utility industries, as those
markets deregulate.
 
  Healthcare
 
   
     In 1991, the Company entered into a long-term, comprehensive information
technology agreement with American Medical Holdings, Inc. ("AMH"), a large
for-profit hospital company. In March 1995, AMH was acquired by Tenet Healthcare
Corporation ("Tenet"), which is the second largest investor-owned healthcare
services company in the United States. At the time of that acquisition, Tenet
invited the Company to propose information technology assistance for the
combined company. After evaluating various approaches, Tenet entered into a
comprehensive agreement with the Company for a full range of information
technology outsourcing and other services.
    
 
   
     Part of Tenet's strategy is to form integrated healthcare delivery systems,
including through the acquisition of hospitals and related ancillary healthcare
businesses. Tenet also occasionally closes or sells certain of its hospitals and
related ancillary healthcare operations that do not fit Tenet's strategic model.
Tenet knew that implementing this strategy would prove challenging from an
information technology perspective and required the Company to develop an
integrated layer of systems that could support the acquisition or disposition of
hospitals and related ancillary healthcare operations.
    
                                       32
<PAGE>   35
 
   
     In its fiscal year ended May 31, 1996, Tenet acquired five general
hospitals, converted one general hospital to a specialty hospital and closed one
hospital. In January 1997, Tenet acquired OrNda Healthcorp and increased the
number of hospitals it owned from 77 to 127. Since that time, Tenet has
continued to change its strategic mix of hospitals. At May 31, 1998, Tenet owned
or operated 122 general hospitals and related ancillary healthcare businesses in
18 states.
    
 
   
     As Tenet has grown the Company has helped Tenet merge disparate networks
into a multi-protocol wide area network and consolidate multiple computing
facilities. This resulted in increased flexibility and reduced costs for Tenet.
The Company developed and implemented a "best-of-breed" applications
architecture that provided access to data from multiple sources and systems to
create unified financial, clinical, materials management, and executive
information systems.
    
 
   
     This relationship has resulted in Tenet having a fast and flexible
information technology capability and infrastructure that provides Tenet with a
strategic advantage as it executes its growth strategy.
    
 
   
     It also has enabled the Company to develop the knowledge and tools to
leverage efficiencies, stabilize and enhance applications, assist others in
forming integrated healthcare networks, and serve other clients in the rapidly
evolving healthcare industry. The Company intends to capitalize on this
experience and expertise to continue to pursue additional opportunities in the
healthcare market.
    
 
   
  Travel and Transportation
    
 
     The car rental industry has recently undergone significant structural
change. Most major car rental companies were previously owned by major
automobile manufacturers, which used the car rental companies to a substantial
degree as a means of purchasing their excess production and as a distribution
channel. Recently, several of the major car rental companies have been acquired
by investors that do not have a business objective of distribution of their
manufactured cars. This development has led to the emergence of new business
strategies in the industry focused more on growth, profit, customer service, and
business change.
 
     National Car Rental is one of the largest car rental firms in the world
with operations in the United States and Europe. National is implementing a
strategic plan for fleet management and customer reservations using technology
to transform the company, provide prompt information about its performance and
markets, and differentiate and improve customer service.
 
     National Car Rental selected the Company over several of its competitors as
its technology partner to assist in the implementation of this plan. In
addressing National's information technology requirements, the Company
successfully replicated a previously devised travel industry "growth engine."
This growth engine enabled the Company to rapidly fashion an integrated business
solution tailored to National's specific needs. The Company and National are
implementing Odyssey, an integrated reservations system, rental operations
system, fleet inventory capability, sales and marketing system, and billing and
collections package. These capabilities will enable National to expand the scope
of its operations, achieve operating efficiencies, differentiate its service
offerings, and rapidly grow its business.
 
     The Company believes that this engagement will augment its existing
expertise and infrastructure in the car rental industry and poise the Company to
exploit other opportunities in this rapidly evolving area.
 
   
  Other Industries
    
 
   
     In February 1998, W.W. Grainger, Inc., a leading distributor of
maintenance, repair and operating supplies in North America, entered into an
agreement with the Company's Time#(TM) unit to develop a digital marketplace to
provide Grainger's small- to medium-sized business customers with one-stop
electronic purchasing of supplies, equipment, and services from multiple
vendors.
    
 
   
     Grainger's digital marketplace will employ business processes and
technology designed to enable buyers, sellers, and others to conduct business
more efficiently and effectively. The marketplace is a collaborative engagement
that brings together extensive knowledge of customer requirements and integrated
capabilities in
    
 
                                       33
<PAGE>   36
 
   
key technology disciplines and e-commerce expertise to create a marketplace
tailored to Grainger's specific needs.
    
 
   
     The systems developed by Time#(TM) will facilitate and enhance customer
relationships and are intended to set a new standard for business-to-business
ordering and acquisition. Through its relationship with Grainger, other clients,
and technology partners, Time#(TM) has built a second generation of its
proprietary technology. The Company believes that this technology will provide
Time#(TM) with an engine for strong growth in Internet commerce.
    
 
PEROT SYSTEMS ASSOCIATES
 
     The market for information technology personnel and business integration
professionals is intensely competitive. A key part of the Company's business
strategy is the hiring, training, and retention of highly motivated personnel
with strong character and leadership traits. The Company believes that employing
associates with such traits is and will continue to be an integral factor in
differentiating the Company from its competitors in the information technology
industry. In seeking such associates, the Company screens candidates for
employment through a rigorous interview process.
 
     The Company devotes a significant amount of resources to training its
associates. Associates undergo continual training throughout their employment
with the Company. Entry level training programs develop the skill sets necessary
to serve the Company's clients. These entry level apprentice training programs
are augmented by engineering development programs and periodic continuing
education. In addition, the Company operates a leadership training course that
each manager and executive must complete. This program includes a workshop
stressing the fundamentals of team leadership. The Company augments its
extensive personnel and leadership training through its TRAIN(TM) (The Real-time
Associate Information Network) system, a company-wide intranet featuring
training courses that develop both technical and leadership skills.
 
     The Company employs a performance-based incentive compensation program that
provides guidelines for career development, encourages the development of
skills, provides a tool to manage the associate development process, and
establishes compensation guidelines as part of its retention program. In
addition to competitive salaries, the Company distributes cash bonuses that are
paid promptly to reward excellent performance. The Company seeks to align the
interests of its associates with those of its stockholders by compensating
outstanding performance with equity interests in the Company, which the Company
believes fosters loyalty and commitment to Company goals. More than 90% of the
Company's associates hold equity interests in the Company.
 
   
     As of September 30, 1998, the Company employed approximately 6,000
associates located in the United States and several other countries. None of the
Company's United States associates is currently employed under an agreement with
a collective bargaining unit. The Company's associates in France and Germany are
generally members of work councils and have worker representatives. The Company
believes that its relations with its associates are good.
    
 
UBS AGREEMENTS
 
     In January 1996, the Company entered into a series of agreements to form a
strategic relationship with Swiss Bank Corporation, one of the predecessors to
UBS. This relationship involves a long-term contract (the "IT Services
Agreement"), and a separate agreement to provide services to other UBS operating
units and to permit the Company to use certain UBS assets. Other agreements with
UBS provide for the sale to UBS of stock and options in the Company, and the
transfer to the Company of a 40% stake in UBS's European information technology
subsidiary, Systor.
 
  IT Services Agreement
 
     Under the IT Services Agreement, the Company provides Warburg Dillon Read,
the investment banking division of UBS, with services meeting its requirements
for the operational management of its technology resources (including
mainframes, desktops, and voice and data networks), excluding hardware and
proprietary
 
                                       34
<PAGE>   37
 
software applications development. The term of the IT Services Agreement is 11
years beginning January 1, 1996. The Company's charges for services provided
under the IT Services Agreement are generally based on reimbursement of all
costs, other than Company corporate overhead, incurred by the Company in the
performance of services covered by the contract. In addition to this cost
reimbursement, the Company receives an agreed annual fee, subject to bonuses and
penalties of up to 15% of such fee related to its performance. UBS determines
the bonus or penalty based on many subjective factors, including service
quality, client satisfaction, and the effectiveness of the Company in assisting
UBS in meeting its business goals.
 
   
     Approximately 25.4% and 27.2% of the Company's revenues were earned in
connection with services performed on behalf of UBS and its affiliates for the
nine months ended September 30, 1998 and the year ended December 31, 1997,
respectively. If some competitors of UBS acquire more than 25% of the shares of
Class A Common Stock of the Company or another party (other than an affiliate of
Ross Perot) acquires more than 50% of the shares of Class A Common Stock and, if
in either case, that acquisition is reasonably likely to have a significant
adverse effect on the performance of or the charges for the services rendered by
the Company, UBS has the right to terminate its agreements with the Company. The
loss of UBS as a client would materially and adversely affect the Company's
business, financial condition, and results of operations.
    
 
  Equity Interests
 
   
     Under the Amended and Restated PSC Stock Option and Purchase Agreement (the
"Stock Agreement"), the Company sold UBS 50,000 shares of Class B Common Stock
for $7.30 a share and 3,617,160 options to purchase shares of Class B Common
Stock for $2.25 an option (the "UBS Options"). UBS can exercise the UBS Options
at any time for $7.30 a share, subject to United States bank-regulatory limits
on UBS's shareholdings. UBS exercised options to purchase 417,160 shares of
Class B Common Stock in September 1998. In addition to other limits set forth in
the Stock Agreement, the number of shares of Class B Common Stock owned by UBS
and its employees may not exceed 10% of the number of shares of outstanding
Common Stock. Once the underlying shares of Class B Common Stock vest, the
corresponding UBS Options are void unless exercised by UBS within five years of
such vesting. This five-year period is tolled at any time when bank-regulatory
limits prohibit UBS from acquiring the shares.
    
 
     Beginning on January 1, 1997, the shares of Class B Common Stock subject to
the UBS Options vest at a rate of 31,953 shares per month until January 1, 2002
and a rate of 29,167 shares per month thereafter until the IT Services Agreement
terminates. Upon termination of the IT Services Agreement, (i) UBS is required
to sell to the Company all unvested shares of Class B Common Stock and (ii) UBS
Options with respect to unvested shares of Class B Common Stock are void.
 
     UBS cannot transfer the UBS Options and unvested shares of Class B Common
Stock. Subject to exceptions relating to certain transfers to UBS affiliates and
transfers in connection with widely dispersed offerings, before transferring any
shares of Class B Common Stock UBS must first offer such shares to the Company.
Because UBS has elected not to sell shares in connection with this offering, UBS
cannot sell Class B Common Stock, except for limited sales to UBS affiliates,
until the first anniversary of the closing date of this offering.
 
     Pursuant to the Stock Agreement, the Company also agreed to issue and sell
to UBS, additional options or shares of Class B Common Stock if UBS, on or prior
to December 31, 1998, enters into an agreement with the Company of the similar
size and scope as the IT Services Agreement covering the remaining operations of
UBS. The purchase price and the exercise price for the additional options or
shares of Class B Common Stock would be an amount per share equal to a defined
fair value for the options or shares of Class B Common Stock as of the date of
the occurrence of such event.
 
     A portion of the Company's interest in Systor will be returned to UBS if
the IT Services Agreement is terminated. The portion that would be returned to
UBS upon such a termination declines ratably over a ten year period which began
on January 1, 1997.
 
                                       35
<PAGE>   38
 
AGREEMENT WITH EME
 
     The Company provides systems services for EME, one of the largest regional
electricity companies in the United Kingdom in terms of distribution volume,
under an Information Technology Services Agreement initially entered into on
April 8, 1992 (as amended, the "EME Agreement"). The EME Agreement remains in
effect until either party gives eight months' prior notice to terminate on or
after March 31, 2004, unless earlier terminated in accordance with the terms of
the EME Agreement. The Company provides systems operation services on the basis
of cost reimbursement and a management fee and applications systems support,
development services, and consultancy services generally on the basis of time
and materials. The EME Agreement also provides for an incentive payment to the
Company if it is able to reduce costs from contract year to contract year.
 
     In addition to termination rights for cause, non-payment, insolvency and an
EME change of control, the EME Agreement also provides for a good faith
termination right that gives either EME or the Company the right to terminate
the EME Agreement upon giving eight months' written notice if in the good faith
view of the terminating party certain objectives of the EME Agreement are not
being met and are unlikely to be achieved.
 
   
     For the nine month period ended September 30, 1998 and the year ended
December 31, 1997, approximately 11.9% and 10.2%, respectively, of the Company's
revenues were earned in connection with services performed on behalf of EME.
    
 
   
     In July 1998, PowerGen plc acquired EME from Dominion Resources, Inc. The
EME Agreement contains provisions allowing EME to terminate all or part of the
contract upon eight months' notice due to the sale of EME. EME is obligated to
pay a termination fee upon exercise of this termination right. The Company
cannot assure that EME will not cancel or modify the contract or that the
Company will maintain its historic level of revenues or profits from this
relationship.
    
 
COMPETITION
 
     The Company's markets are intensely competitive and are characterized by
continuous changes in customer requirements and the technology available to
satisfy those requirements.
 
     The Company's principal competitors include Andersen Consulting LLP,
Cambridge Technology Partners, Inc., Cap Gemini Group, Computer Sciences
Corporation, debis Systemhaus GmbH (the information technology division of
Daimler-Benz AG), Electronic Data Systems Corporation, Ernst & Young LLP, IBM
Global Services (a division of International Business Machines, Inc.), KPMG Peat
Marwick LLP, MCI Systemhouse, Oracle Corporation, PricewaterhouseCoopers LLP,
and The SABRE Group Holdings, Inc.
 
     Many of these companies, as well as some other competitors, have greater
financial resources and larger customer bases than the Company and may have
larger technical, sales, and marketing resources than the Company. The Company
expects to encounter additional competition as it addresses new markets and as
the computing and communications markets converge. In addition, the Company must
frequently compete with a client's own internal information technology
capability, which may constitute a fixed cost for the client. This may increase
pricing pressure on the Company.
 
     The Company competes on the basis of a number of factors, both within and
outside of its control, including the attractiveness of the business strategy
and services that the Company offers, breadth of service line offerings,
technological innovation, pricing, quality of service, and ability to invest in
or acquire assets of potential customers. The Company differentiates itself from
its competitors by providing clients with integrated service offerings,
emphasizing the creation of long-term relationships with its clients, and
working with the client to define the business problem to be solved and the
potential business opportunity from the point of view of the client and the
client's customers. There can be no assurance that the Company will be able to
compete successfully against its current or future competitors in the future or
that competition will not have a material adverse effect on the Company's

INTELLECTUAL PROPERTY
 
     While the Company attempts to retain intellectual property rights arising
from client engagements, the Company's clients often have the contractual right
to retain such intellectual property. The Company relies on a combination of
nondisclosure and other contractual arrangements and trade secret, copyright,
and trademark laws to protect its proprietary rights and the proprietary rights
of third parties from whom the Company licenses intellectual property. The
Company enters into confidentiality agreements with its associates and limits
distribution of proprietary information. There can be no assurance that the
steps taken by the Company in this regard will be adequate to deter
misappropriation of proprietary information or that the Company will be able to
detect unauthorized use and take appropriate steps to enforce its intellectual
property rights.
 
     The Company licenses the right to use the names "Perot Systems" and "Perot"
(collectively, the "Perot Name") in its current and future businesses, products,
or services from the Perot Systems Family Corporation and Ross Perot. The
license is a non-exclusive, royalty-free, worldwide, non-transferable license.
The Company may also sublicense its rights to the Perot Name to its affiliates.
Under the license agreement, as amended, either party may, in their sole
discretion, terminate the license at any time, with or without cause and without
penalty, by giving the other party written notice of such termination. Upon
termination by either party, the Company must discontinue all use of the Perot
Name within one year following receipt of the notice of termination. The
termination of this license agreement may materially and adversely affect the
Company's business, financial condition, and results of operations. Except for
the license of the Company's name, the Company does not believe that any
particular copyright, trademark or group of copyrights and trademarks is of
material importance to the Company's business taken as a whole.
 
PROPERTIES
 
   
     As of September 30, 1998, the Company had approximately 40 locations in the
United States and five countries outside the United States, all of which were
leased. The Company's leases cover approximately 1.0 million square feet of
office and other facilities and have expiration dates ranging from 1998 to 2016.
Upon expiration of its leases, the Company does not anticipate any significant
difficulty in obtaining renewals or alternative space. In addition to the leased
property referred to above, the Company occupies office space at client
locations throughout the world. Such space is generally occupied pursuant to the
terms of the agreement with the particular client. The Company currently
anticipates consolidating some or all of its operations located principally in
Dallas, Texas during the next two years. The Company's management believes that
its current facilities are suitable and adequate for its business.
    
 
OPERATING LEASES AND MAINTENANCE AGREEMENTS
 
     The Company has commitments related to data processing facilities, office
space, and computer equipment under non-cancelable operating leases and fixed
maintenance agreements for periods ranging from one to ten years. Future minimum
commitments under these agreements as of December 31, 1997 are disclosed in Note
13 to the Consolidated Financial Statements.
 
LEGAL PROCEEDINGS
 
     The Company is, from time to time, involved in various litigation matters
arising in the ordinary course of its business. The Company believes that the
resolution of currently pending legal proceedings, either individually or taken
as a whole, will not have a material adverse effect on the Company's
consolidated financial position or results of operations.

BOARD COMMITTEES AND MEETINGS
 
   
     The Board of Directors has established two committees to assist in the
discharge of its responsibilities: the Executive Committee and the Audit
Committee. The Executive Committee consists of Ross Perot, Ross Perot, Jr., and
Steven Blasnik. The Audit Committee consists of William Gayden and Carl Hahn.
    
 
     The Executive Committee has the full power and authority of the Board of
Directors in the management of the business and affairs of the Company, except
with respect to matters that cannot be delegated under Delaware law.
 
     The Audit Committee reviews the annual financial statements of the Company
and the professional services provided by the Company's independent public
accountants, including the scope of their audit coverage, the auditor's reports
to management and management's responses to such reports, and the independence
of such accountants from the management of the Company. The Audit Committee also
reviews the scope of the Company's internal audits, the internal auditors'
reports to management and management's responses to such reports, the
effectiveness of the Company's internal audit staff, possible violations of the
Company's Standards and Ethical Principles, and such other matters with respect
to the accounting, auditing and financial reporting practices and procedures of
the Company as it may find appropriate or as have been brought to its attention.
 
     The Board of Directors may, from time to time, establish other committees
to facilitate the management of the Company or for other purposes it may deem
appropriate.
 
DIRECTOR COMPENSATION
 
     In October 1997, the Company began compensating its non-employee directors
(other than Ross Perot, Jr.) $2,000 for each meeting of the Board of Directors
attended in person. Employee directors receive no cash compensation for
attending committee meetings. Directors are also reimbursed for their reasonable
out-of-pocket expenses associated with attending Board of Directors and
committee meetings. Prior to October 1997, directors received no cash
compensation for their service on the Board of Directors or any committee of the
Board of Directors.
 
     Except for Mr. Hahn, prior to December 1996, upon their election to the
Board of Directors, non-employee directors (other than affiliates of Ross Perot)
were offered either (i) the opportunity to purchase 60,000 restricted shares of
Class A Common Stock or (ii) the grant of an option to acquire 60,000 shares of
Class A Common Stock at a purchase or exercise price equal to the fair value of
such Class A Common Stock at the date of purchase or grant, with such restricted
shares of Class A Common Stock or options to acquire shares of Class A Common
Stock vesting ratably over a five-year period. In April 1993, Mr. Hahn received
200,000 restricted shares of Class A Common Stock at a price equal to the fair
value of such shares at the date of purchase, which vest ratably over a
five-year period.
 
     In December 1996, the Company adopted the 1996 Non-Employee Director Stock
Option/Restricted Stock Plan (the "Non-Employee Director Plan"). The
Non-Employee Director Plan provides for the issuance of nonqualified stock
options or restricted stock to non-employee directors of the Company and any of
its majority-owned subsidiaries. The Non-Employee Director Plan is administered
by the Board of Directors, which has the authority to interpret the Non-Employee
Director Plan. Directors eligible to receive awards under the Non-Employee
Director Plan are those (other than Ross Perot, Jr.) who are not employees of
the Company. Each eligible existing director will receive comparable grants at
completion of the original vesting schedule for such director's current options
or restricted shares. Grants are made upon election to the Board of Directors
for new directors and, for existing directors, at completion of the original
vesting schedule for the director's existing options or restricted shares. The
Non-Employee Director Plan provides for a grant to each eligible director of (i)
an option to purchase 20,000 shares of Class A Common Stock or (ii) the right to
purchase 20,000 restricted shares of Class A Common Stock. (The number of shares
of Class A Common Stock or options issuable to each director were reduced from
30,000 to 20,000 on September 30, 1997.) The exercise price of options or the
purchase price of restricted shares of Class A Common Stock awarded under
 
                                       40
<PAGE>   43
 
the Non-Employee Director Plan must be at least equal to 100% of the fair value
of a share of Class A Common Stock on the date of the award.
 
   
     Mr. Hahn purchased 20,000 shares of Restricted Stock under the Non-Employee
Director Plan in May 1998. In November 1998, the Company issued Mr. Gayden
options to purchase 20,000 shares of Class A Common Stock.

(1) There is currently no market for the shares of Class A Common Stock.
    Therefore, the values set forth in these columns are based on periodic
    appraisals of the shares of Class A Common Stock made for the Company by
    independent appraisers.
 
(2) Following Mr. Marmol's resignation from the Company, options held by him to
    purchase 80,000 shares of Class A Common Stock expired unvested.
 
EMPLOYMENT CONTRACTS AND CHANGE IN CONTROL AGREEMENTS
 
     Morton Meyerson. Mr. Meyerson's assignee, the Meyerson Family Limited
Partnership ("MFLP"), purchased 4,000,000 shares of Class A Common Stock from
the Company pursuant to the terms of a stock purchase agreement between Mr.
Meyerson and the Company (the "MFLP Agreement"). Under the MFLP Agreement, prior
to June 1997, the Company had the right to repurchase a portion of the shares of
Class A Common Stock held by the MFLP Partnership if Mr. Meyerson voluntarily
resigned as Chairman unless the parties agreed to an arrangement for Mr.
Meyerson to remain with the Company. In June 1997, the Company's right to
repurchase shares of Class A Common Stock held by the MFLP terminated.
 
     In December 1995, Mr. Meyerson purchased 200,000 restricted shares of Class
A Common Stock pursuant to the terms of a Restricted Stock Agreement between Mr.
Meyerson and the Company (the "Meyerson Agreement"). Under the Meyerson
Agreement, the Company had the right to purchase unvested shares of Class A
Common Stock if Mr. Meyerson voluntarily resigned. There were 28,800 unvested
shares of Class A Common Stock at Mr. Meyerson's resignation in January 1998.
The Company exercised its right to repurchase for a price equal to Mr.
Meyerson's cost plus 8% interest per annum.
 
     James Cannavino. Mr. Cannavino's employment agreement (the "Cannavino
Agreement") with the Company provided for a base salary of $500,000 per year,
subject to adjustment from time to time by the Board of Directors. Mr.
Cannavino's base salary was increased by the Board to $600,000 for 1997. On July
25, 1997, Mr. Cannavino resigned his positions with the Company. Under the terms
of the Cannavino Agreement, Mr. Cannavino will receive a severance payment equal
to two years of his highest base salary. The second year's salary will be
reduced by amounts earned by Mr. Cannavino from other sources during that year.
 
   
     The 2,000,000 restricted shares of Class A Common Stock acquired by Mr.
Cannavino pursuant to his stock option grant were scheduled to vest in equal
installments over ten years beginning on the first anniversary of the
commencement of Mr. Cannavino's employment by the Company. Mr. Cannavino's
restricted shares of Class A Common Stock are scheduled to continue to vest
through October 1998. The Company has repurchased 1,400,000 of the shares of
Class A Common Stock formerly owned by Mr. Cannavino that will not vest under
the terms of his stock option grant for a price equal to his after-tax cost of
purchase for those shares plus 8% per annum. Mr. Cannavino continues to hold
550,000 shares of Class A Common Stock. Mr. Cannavino has transferred 50,000
shares of Class A Common Stock to his former spouse. If the shares of Class A
Common Stock are not publicly traded prior to the year 2010, Mr. Cannavino has
the right to require the Company to repurchase his shares of Class A Common
Stock at their then fair value.
    
 
     James Champy. Mr. Champy's associate agreement provides for a base salary
of $500,000 per year, which is to be reviewed at least annually. Mr. Champy's
associate agreement provides for additional benefits, including: (i) a bonus to
be determined in accordance with the then current bonus plan applicable to the
most senior officers of the Company, (ii) payment of life insurance premiums and
(iii) some travel benefits. Mr. Champy's associate agreement also provides that,
in the event that Mr. Champy is terminated by the Company other than for cause
or substantial misconduct (as defined in his associate agreement) or Mr. Champy
is deemed to have been constructively terminated (as defined in his associate
agreement), Mr. Champy will receive a severance payment equal to six months of
Mr. Champy's then current base salary. If Mr. Champy's employment is terminated
by either party (other than for cause by the Company) within one year of a
change in control of the Company (as defined in his associate agreement), Mr.
Champy would be entitled to receive a severance payment equal to six months of
Mr. Champy's then current base salary.
 
     The 500,000 restricted shares of Class A Common Stock acquired by Mr.
Champy pursuant to his restricted stock agreement vest in equal installments
over ten years beginning on the first anniversary of the
 
                                       44
<PAGE>   47
 
   
commencement of Mr. Champy's employment by the Company. Vesting is contingent on
continued employment; provided, however, that Mr. Champy's restricted shares of
Class A Common Stock will continue to vest for limited periods following the
termination of his employment if his employment is terminated by the Company
other than for cause or substantial misconduct (as defined in his associate
agreement) or Mr. Champy is deemed to have been constructively terminated (as
defined in his associate agreement). If Mr. Champy's employment is terminated by
the Company other than for cause or substantial misconduct, Mr. Champy's
restricted shares of Class A Common Stock will continue to vest as scheduled for
two years following termination of employment. If there is a change in control
of the Company (as defined in his associate agreement) and Mr. Champy's
employment is terminated within one year of such change in control by either
party (other than for cause by the Company), all of Mr. Champy's shares of Class
A Common Stock scheduled to vest through the next two vesting dates will vest on
schedule. In the event that Mr. Champy is terminated for any reason by either
party, Mr. Champy has the right to require the Company to purchase his shares
for their original cost plus simple interest at the rate of 8% per annum.
    
 
     Terry Ashwill. Pursuant to the letter agreement pursuant to which Mr.
Ashwill accepted employment with the Company, he is assured that at least 50,000
options and/or shares of the Company's stock will vest if his employment is
terminated (i) by Mr. Ashwill and he does not work for a competitor of the
Company for 12 months or, within six months of the date of termination, work for
a company with which he discussed employment prior to the termination of his
employment or (ii) by the Company without cause. This special vesting provision
is only applicable to the extent necessary to cause the value of vested shares
and options to be equal to $1,500,000 on the third anniversary of his employment
by the Company. In addition, the Company agreed to pay some expenses related to
Mr. Ashwill's relocation to Dallas.
 
STOCK PLANS
 
     The Company's currently active stock plans include: the 1991 Stock Option
Plan, Restricted Stock Plan, 1996 Non-Employee Directors Plan (the "Non-Employee
Directors Plan") and 1996 Advisors and Consultants Plan (collectively, the
"Plans"). In addition, the Company has options that remain outstanding under its
former Advisors and Consultants Plan, which was terminated in 1996.
 
     The purpose of the Plans is to attract and retain outstanding associates,
directors, consultants, and advisors and provide them with a strong incentive to
contribute to the success of the Company by granting them options to acquire, or
allowing them to purchase, shares of Class A Common Stock. The Plans are not
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), nor do they meet the requirements of Section 401(a) of the Internal
Revenue Code of 1986, as amended (the "Code").
 
   
     As of September 30, 1998, an aggregate of 6,102,638 shares of Class A
Common Stock were available for issue under the Plans (other than the
Non-Employee Directors Plan under which 340,000 shares of Class A Common Stock
were available). Shares of Class A Common Stock available under the Plans or
subject to existing Stock Option Agreements are subject to adjustment in the
event of a stock dividend, stock split, or merger or consolidation to preserve
the respective rights of the participants in the respective Plans. Subsequent to
September 30, 1998, 106,400 shares of Class A Common Stock have become subject
to issuance on exercise of outstanding options at an exercise price equal to the
initial public offering price (if this offering is completed by January 20,
1999) or otherwise as determined by the Board of Directors.
    
 
1998 ASSOCIATE STOCK PURCHASE PLAN
 
   
     The Board of Directors adopted the 1998 Associate Stock Purchase Plan (the
"1998 Employee Stock Purchase Plan") to become effective immediately after this
offering. A summary of the material features of the 1998 Employee Stock Purchase
Plan follows. Capitalized terms not defined in this Prospectus have the meaning
given them in the 1998 Employee Stock Purchase Plan.
    
 
   
     General. The purpose of the 1998 Employee Stock Purchase Plan is to provide
employees of the Company and of majority owned subsidiaries ("Participating
Affiliates") of the Company with the opportunity and a convenient means to
purchase Common Stock of the Company at a discount from the market price through
a program of voluntary, regular payroll deductions. The Company intends to have
the 1998 Employee Stock Purchase Plan qualify as an "Employee Stock Purchase
Plan" under Section 423 of the Code.
    
 
                                       45
<PAGE>   48
 
   
     A total of 10,000,000 shares of Class A Common Stock are authorized and
reserved for issuance under the 1998 Employee Stock Purchase Plan. Appropriate
adjustments in the aggregate number of shares subject to the 1998 Employee Stock
Purchase Plan will be made in the event of any merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company.
    
 
   
     The 1998 Employee Stock Purchase Plan permits "Eligible Associates" to
participate in the plan. An Eligible Associate is generally an employee of the
Company and Participating Affiliates who works more than 20 hours per week on a
regular basis and is not engaged under an independent contractor or similar
agreement, whether or not such person is determined to be an independent
contractor. Eligible Associates who own five percent or more of the Company's
outstanding Class A Common Stock may not purchase shares under the 1998 Employee
Stock Purchase Plan.
    
 
   
     The 1998 Employee Stock Purchase Plan permits Eligible Associates to
purchase, through regular payroll deductions, shares of Common Stock at a price
equal to 85% of the fair market value of one share of the Class A Common Stock
on the Exercise Date for the Offering Period.
    
 
   
     The Board of Directors may amend the 1998 Employee Stock Purchase Plan
without notice, at any time, subject to certain restrictions set forth in the
1998 Employee Stock Purchase Plan. The 1998 Employee Stock Purchase Plan will
automatically terminate after ten years, or on the date all shares authorized to
be sold under the 1998 Employee Stock Purchase Plan have been sold, subject to
the right of the Board of Directors to terminate the 1998 Employee Stock
Purchase Plan at an earlier time.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     The Company licenses the right to use the Perot Name in its current and
future businesses, products, or services from the Perot Systems Family
Corporation and Ross Perot. The license is a non-exclusive, royalty-free,
non-transferable license without geographic restriction. The Company may also
sublicense its rights to the Perot Name to its affiliates. Under the License
Agreement, as amended, either party may, in their sole discretion, terminate the
license at any time, with or without cause and without penalty, by giving the
other party written notice of such termination. Upon termination by either
party, the Company must discontinue all use of the Perot Name within one year
following receipt of the notice of termination.
 
   
     The Company made loans to each of Ron Nash, Joseph Boyd, Guillermo Marmol
(a former executive), and Susan Fairty (a former executive) in connection with
the purchase by such persons of shares of Class A Common Stock from the Company.
Each of such loans accrues interest at the rate of 8% per annum and is secured
by the purchased stock. As of September 30, 1998, the total amount outstanding
for each such loan (including accrued interest) was $257,386, $72,194, $0, and
$0 for Messrs. Nash, Boyd, Marmol, and Ms. Fairty, respectively. The highest
amounts outstanding under such loans since January 1, 1996 were as follows: Mr.
Nash, $268,045; Mr. Boyd, $75,999; Mr. Marmol, $136,288; and Ms. Fairty,
$582,839.
    
 
   
     The Company made loans to Terry Ashwill in connection with his purchase of

interest at the rate of 8% per annum and were secured by the purchased stock. On
December 23, 1997, the aggregate amount outstanding for Mr. Ashwill's loans
(including accrued interest) was $474,489, the highest amount outstanding with
respect to such loans since their inception. On December 23, 1997, the Company
repurchased the 120,000 shares of Class A Common Stock held by Mr. Ashwill for
$3.75 per share plus 8% per annum for the time that he held the stock (an
aggregate of $481,364). The Company paid the purchase price of the stock by
offsetting the amounts due Mr. Ashwill against the principal and accrued
interest on his loans and paying the remaining $6,875 in cash (which is equal to
amounts previously paid by Mr. Ashwill for interest that had accrued on his
loans). In connection with the repurchase, the Company granted Mr. Ashwill
options to purchase 120,000 shares of Class A Common Stock with an exercise
price of $6.75 per share.
    
 
   
     On August 27, 1997, the Company loaned $250,000 to John King secured by his
shares of Class A Common Stock. Mr. King's loan accrues interest at 8% per
annum. The total amount outstanding for Mr. King's loan (including accrued
interest) on September 30, 1998 was $278,121, the highest amount outstanding
since the inception of the loan.
    
 
   
     The Company has made loans to James Cannavino secured by his shares of
Class A Common Stock. As of September 30, 1998, Mr. Cannavino had the
outstanding principal amounts of $420,000 and $1,169,624 accruing interest at
the rates of 8% per annum and 7.25% per annum, respectively. As of September 30,
1998, the aggregate amount outstanding (including accrued interest) relating to
these loans was $1,811,416. The highest amount outstanding with respect to such
loans (including accrued interest) since its inception was $3,679,285. The
Company also loaned Mr. Cannavino $1,000,000 in connection with his purchase of
a permanent residence in Dallas. This loan is secured by a mortgage on such
residence and bears interest at 7.25% per year. As of September 30, 1998, the
total amount outstanding (including accrued interest) relating to this loan was
$1,054,425. Since its inception, the highest amount outstanding for this loan
was $1,054,425.
    
 
   
     Messrs. Nash, Drobny, and Altabef have outstanding loans with NationsBank
of Texas, N.A. ("NationsBank") in the respective principal amounts of $207,867,
$350,000, and $126,400. Interest accrues on all such loans at the rate of 9.75%
for Messrs. Nash and Altabef and 9.5% for Mr. Drobny. The Company had agreed
that it would, at the request of NationsBank, purchase such loans from
NationsBank for an amount equal to principal plus accrued and unpaid interest if
the Company has not had an initial public offering that results in the shares of
Class A Common Stock being publicly traded before the maturity of the notes. The
maturity dates are February 26, 2000, July 1, 2000, and July 20, 2000 for
amounts borrowed by Messrs. Drobny, Nash, and Altabef, respectively. Each loan
is secured by a pledge of shares of Class A Common Stock held by the borrower.

     In January 1996, the Company entered into an agreement with PII pursuant to
which the Company licensed some software from PII. PII is an affiliate of Ross
Perot. Mr. Blasnik is the President of PII. The Company sublicensed such
software to The Witan Company L.P. ("Witan"). In connection with this project,
Witan paid a license fee of $1,000,000 directly to PII in connection with the
license. The Company had a separate contract with Witan to perform development
work on the licensed software, which was terminated in May 1997.
    
 
   
     For the year ended December 31, 1997, and for the ten month period ended
October 31, 1998, the Company paid $91,425 and $192,976, respectively, to the
law firm of Locke Purnell Rain Harrell for services rendered to the Company. The
spouse of Mr. Altabef is a shareholder of that firm.
    
 
   
     For the years ended December 31, 1995, 1996, and 1997, and for the ten
month period ended October 31, 1998, the Company paid to Hughes & Luce, L.L.P.
$394,509, $635,665, $650,779, and $337,403, respectively, for services rendered
to the Company. A partner in that firm is a son-in-law of Mr. Perot.

(1) The address for Ross Perot, Ross Perot, Jr., and HWGA, Ltd. ("HWGA") is
    12404 Park Central Drive, Dallas, Texas 75251. The address for Mr. Meyerson
    is 4514 Cole Ave., Suite 400, Dallas, Texas 75205.
    
 
   
(2) Percentages are based on the total number of shares of Common Stock
    outstanding at September 30, 1998, plus the total number of outstanding
    options and warrants held by each person that are exercisable within 60 days
    of such date. Shares of Common Stock issuable upon exercise of outstanding
    options and warrants, however, are not deemed outstanding for purposes of
    computing the percentage ownership of any other person. Except as indicated
    in the footnotes to this table, other than shared property rights created
    under joint tenancy or marital property laws as between the Company's
    directors and executive officers and their respective spouses, each
    stockholder named in the table has sole voting and investment power with
    respect to the shares of Class A Common Stock set forth opposite such
    stockholder's name. The shares of Class A Common Stock listed include shares
    of Class A Common Stock held by the Company's Retirement Savings Plan and
    Trust for the benefit of the named individuals. Voting and investment power
    over such shares of Class A Common Stock is held by the trustee of such
    trust subject to the direction of the Company's 401(k) Plan Committee.
    
 
   
(3) Shares are owned by HWGA. Ross Perot, Chairman, President, and Chief
    Executive Officer of the Company, is the managing general partner of HWGA.
    Mr. Perot has voting and investment power over such shares. Ross Perot, Jr.
    is a general partner of HWGA who has authority to manage HWGA if Ross Perot
    ceases to be managing general partner of HWGA. Accordingly, shares owned by
    HWGA are also shown in this table as being beneficially owned by Ross Perot,
    Jr. On August 5, 1998, Mr. Perot agreed to acquire an additional 200,000
    shares of Class A Common Stock from an existing stockholder at a price per
    share equal to the initial public offering price less $.10 per share.

 (4) Includes 100,000 shares of Class A Common Stock held by the Champy Family
     Irrevocable Trust (the "Champy Trust") of which Mr. Champy is a trustee. As
     trustee, Mr. Champy shares voting and investment power with respect to the
     shares of Class A Common Stock held by the Champy Trust and, therefore, is
     deemed the beneficial owner of such shares of Class A Common Stock.
 
 (5) Includes 2,000 shares of Class A Common Stock held by Mr. King's spouse
     with respect to which Mr. King shares voting and investment power.
 
 (6) Includes 40,000 shares of Class A Common Stock that Mr. Ashwill has the
     right to acquire upon the exercise of vested options.
 
 (7) Includes 2,000 shares of Class A Common Stock held by Mr. Reeves' spouse
     with respect to which Mr. Reeves shares voting and investment power and

     acquire upon the exercise of vested options.
 
   
 (8) Includes 4,000 shares of Class A Common Stock held by Mr. Marmol's children
     over which Mr. Marmol's father has voting and investment power.
    
 
 (9) Includes 3,000 shares of Class A Common Stock held by Mr. Blasnik's spouse.
     Mr. Blasnik disclaims beneficial ownership of such shares.

     trusts of which Mr. Meyerson is the Trustee.

                          DESCRIPTION OF CAPITAL STOCK
 
   
     The authorized capital stock of the Company currently consists of
229,000,000 shares, of which 200,000,000 shares are designated as Class A Common
Stock, $.01 par value per share, 24,000,000 shares are designated as Class B
Common Stock, $.01 par value per share, and 5,000,000 shares are designated as
Preferred Stock, $.01 par value per share. As of September 30, 1998, there were
38,447,277 shares of Class A Common Stock issued and outstanding and held of
record by 1,436 stockholders, 467,160 shares of Class B Common Stock issued and
outstanding and held of record by one stockholder, and no shares of Preferred
Stock issued and outstanding. In addition, a total of 18,283,177 shares of
Common Stock is reserved for issuance upon exercise of options outstanding as of
the date of this Prospectus.
    
 
CLASS A COMMON STOCK
 
     Holders of shares of Class A Common Stock are entitled to one vote per
share for each share held of record on any matter submitted to the holders of
Common Stock for a vote. All shares of Class A Common Stock and Class B Common
Stock outstanding are fully paid and nonassessable, and all of the shares of
Class A Common Stock and Class B Common Stock to be outstanding upon completion
of this offering will be fully paid and nonassessable. Subject to the rights of
the holders of any outstanding shares of Preferred Stock and any restrictions
that may be imposed by any lender to the Company, holders of Class A Common
Stock are entitled to receive such dividends, if any, as may be declared by the
Board of Directors out of legally available funds. In the event of the
liquidation, dissolution or winding up of the Company, holders of Class A Common
Stock are entitled to share equally and ratably, based on the number of shares
held, in the assets, if any, remaining after payment of all of the Company's
debts and liabilities and the liquidation preference of any outstanding
Preferred Stock. The shares of Class A Common Stock are neither redeemable nor
convertible, and the holders of Class A Common Stock have no preemptive rights
to subscribe for or purchase any additional shares of capital stock issued by
the Company.
 
CLASS B COMMON STOCK
 
     Holders of shares of Class B Common Stock have no voting rights, except to
the extent that the Delaware General Corporation Law requires a vote of the
Class B Common Stock with respect to an amendment to the Amended and Restated
Certificate of Incorporation that would increase or decrease the par value of
the Class B Common Stock or alter or change the powers, preferences, or special
rights of shares of Class B Common Stock so as to affect them adversely. The
Amended and Restated Certificate of Incorporation provides that the number of
authorized shares of Class B Common Stock may be increased or decreased (but not
below the number of shares of Class B Common Stock then outstanding or reserved
for issuance pursuant to outstanding options, warrants or similar rights) by the
affirmative vote of the holders of a majority of the voting stock of the
Company, voting as a single class, without any vote by the holders of the Class
B Common Stock. Subject to the rights of the holders of any outstanding shares
of Preferred Stock and any restrictions that may be imposed by any lender to the
Company, holders of Class B Common Stock are entitled to receive such dividends,
if any, as may be declared by the Board of Directors out of legally available
funds. In the event of the liquidation, dissolution or winding up of the
Company, holders of Class B Common Stock are entitled to share equally and
ratably, based on the number of shares held, in the assets, if any, remaining
after payment of all of the Company's debts and liabilities and the liquidation
preference of any outstanding Preferred Stock. Each share of Class B Common
Stock is convertible, on a share for share basis, at the option of the holder
into a fully paid and nonassessable share of Class A Common Stock for the
purpose of the transfer, sale, or other disposition to a third party purchaser
that is not an affiliate of UBS if such sale is made (a) in a widely dispersed
public offering of the Class A Common Stock, (b) to a third party that, prior to
such sale, controls more than 50% of the then outstanding voting securities of
the Company, (c) to a third party that, after such sale, is the beneficial owner
of not more than 2% of the outstanding voting stock of the Company having power
to elect directors, (d) in a transaction that complies with Rule 144 of the
Securities Act of 1933, as amended (the "Securities Act"), or (e) by UBS or its
affiliates in a transaction approved in advance by the Board of Governors of the
Federal Reserve System. UBS is the only holder of Class B Common Stock.

PREFERRED STOCK
 
   
     The Company is authorized to issue shares of Preferred Stock in one or more
series, and to designate the rights, preferences, limitations, and restrictions
of and upon shares of each series, including voting, redemption, and conversion
rights. The Board of Directors also may designate dividend rights and
preferences in liquidation. It is not possible to state the actual effect of the
authorization and issuance of additional series of Preferred Stock upon the
rights of holders of Common Stock until the Board of Directors determines the
specific terms, rights and preferences of a series of Preferred Stock. Such
effects, however, might include, among other things, granting the holders of
Preferred Stock priority over the holders of Common Stock with respect to the
payment of dividends, diluting the voting power of the Common Stock, or granting
the holders of Preferred Stock preference with respect to liquidation rights. In
addition, under some circumstances, the issuance of Preferred Stock may render
more difficult or tend to discourage a merger, tender offer or proxy contest,
the assumption of control by a holder of a large block of the Company's
securities or the removal of incumbent management.
    
 
REGISTRATION RIGHTS
 
   
     Pursuant to a Stock Purchase Agreement dated August 20, 1992 between the
Company and MFLP (which Morton Meyerson, former Chairman of the Company,
controls), the Company sold to MFLP 4,000,000 shares of Class A Common Stock,
and in connection with such sale, granted MFLP "piggyback" registration rights
for such shares of Class A Common Stock. MFLP's "piggyback" registration rights
do not apply in this offering. These registration rights could arise in
connection with any other offering to the public under the Securities Act on
Form S-1, S-2, or S-3, or any successor registration form then in effect.
    
 
DELAWARE TAKEOVER STATUTE
 
   
     The Company is subject to Section 203 of the Delaware General Corporation
Law, which prohibits a Delaware corporation from engaging in a "business
combination" with certain persons ("Interested Stockholders") for three years
following the time any such person becomes an Interested Stockholder unless (i)
before a person becomes an Interested Stockholder, the Board of Directors of the
corporation approved the transaction in which the Interested Stockholder became
an Interested Stockholder or approved the business combination, (ii) upon
consummation of the transaction that resulted in the Interested Stockholder
becoming an Interested Stockholder, the Interested Stockholder owned at least
85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the number of
shares outstanding those shares owned by (a) persons who are directors and also
officers and (b) employee stock plans in which employee participants do not have
the right to determine confidentially whether shares held subject to the plan
will be tendered in a tender or exchange offer, or (iii) at or subsequent to the
time the person became an Interested Stockholder, the business combination is
approved by the Board of Directors of the corporation and authorized at a
regular or special meeting of stockholders, and 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.
    
 
     In general, an Interested Stockholder means any person that (i) is the
beneficial owner of 15% or more of the outstanding voting stock of the
corporation or (ii) is an affiliate or associate of the corporation and was the
beneficial owner of 15% or more of the corporation's outstanding voting stock at
any time within three years before the date on which such person's status as an
Interested Stockholder is determined.
 
     Subject to some exceptions, a business combination includes, among other
things, (i) mergers or consolidations, (ii) the sale, lease, exchange, mortgage,
pledge, transfer or other disposition of assets having an aggregate market value
equal to 10% or more of either the aggregate market value of all assets of the
corporation determined on a consolidated basis or the aggregate market value of
all the outstanding stock of the corporation, (iii) transactions that result in
the issuance or transfer by the corporation or any majority-owned subsidiary of
any stock of the corporation to the Interested Stockholder, except pursuant to
certain corporate distributions and issuances that do not increase the
Interested Stockholder's proportionate shareholding, (iv) any transaction
involving the corporation that has the effect of increasing the proportionate
 
                                       52
<PAGE>   55
 
share of the stock of any class or series, or securities convertible into the
stock of any class or series, of the corporation that is owned directly or
indirectly by the Interested Stockholder, or (v) any receipt by the Interested
Stockholder of the benefit (except proportionately as a stockholder) of any
loans, advances, guarantees, pledges or other financial benefits provided by or
through the corporation.
 
PROVISIONS RELATING TO CHANGE IN CONTROL
 
  Stockholder Rights Plan
 
   
     The Company's Board of Directors has authorized a Stockholder Rights Plan
(the "Rights Plan") that provides that one Class A right (a "Class A Right")
will be attached to each share of Class A Common Stock and one Class B right (a
"Class B Right", and together with the Class A Rights, the "Rights") will be
attached to each share of Class B Common Stock as of        , 1998 (the "Record
Date"). Each Class A Right will entitle the registered holder to purchase from
the Company a unit consisting of one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share (the "Series A Preferred
Stock"), at a purchase price of $       per Unit (the "Purchase Price"), subject
to adjustment. Each Class B Right entitles the registered holder to purchase
from the Company a unit consisting of one one-hundredth of a share of Series B
Junior Participating Preferred Stock, par value $.01 per share (the "Series B
Preferred Stock" and, together with the Series A Preferred Stock, the "Preferred
Stock"), at the Purchase Price of $     per unit (the "Purchase Price"), subject
to adjustment. The description and terms of the Rights are set forth in the
Rights Agreement (the "Rights Agreement"), dated as of        , 1998, between
the Company and        , as Rights Agent (the "Rights Agent").
    
 
   
     Initially, the Class A Rights will be attached to all Class A Common Stock
certificates representing shares outstanding as of the Record Date and the Class
B Rights will be attached to all Class B Common Stock certificates representing
shares outstanding as of the Record Date, and no separate Rights Certificate
will be distributed. The Rights will separate from the Common Stock and a
Distribution Date (as defined in the Rights Plan) will occur upon the earlier of
(i) 10 days following a public announcement that a person or group of affiliated
or associated persons (an "Acquiring Person") has acquired, or obtained the
right to acquire, beneficial ownership of 20% or more of the outstanding shares
of Common Stock or 20% or more of the outstanding shares of Class A Common Stock
(the "Stock Acquisition Date"), (ii) 10 business days following the commencement
of a tender offer or exchange offer that would result in a person or group
beneficially owning 20% or more of the outstanding shares of Common Stock or 20%
or more of the outstanding shares of Common Stock or (iii) 10 business days
after the Board of Directors of the Company determines that any person or
persons have become the beneficial owner of an amount of Common Stock that the
Board of Directors determines to be substantial (which amount will in no event
be less than 10% of the shares of Common Stock outstanding) and that (a) such
person or persons intend to cause the Company to repurchase the Common Stock
beneficially owned by such person or persons or to exert pressure against the
Company to take any action or enter into any transaction or series of
transactions with the intent or the effect of providing such person or persons
with short-term gains or profits under circumstances in which the Board of
Directors determines that the long-term interests of the Company and its
stockholders would not be served by taking such action or entering into such
transactions or series of transactions or (b) beneficial ownership by such
person or persons is reasonably likely to have a material adverse effect on the
business, competitive position, prospects, or financial condition of the Company
and its subsidiaries (an "Adverse Person"). Until the Distribution Date, (i) the
Rights will be evidenced by the Common Stock certificates and will be
transferred with and only with such Common Stock certificates, (ii) new Common
Stock certificates will contain a notation incorporating the Rights Agreement by
reference; and (iii) the surrender for transfer of any certificates for Common
Stock outstanding will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificate.
    
 
   
     The Rights Agreement will provide that Ross Perot, and certain of his
successors and affiliates, who together will be beneficial owners of more than
42% of the Common Stock of the Company outstanding on        , 1998, are
excluded from the definitions of "Acquiring Person" and "Adverse Person." Mr.
Perot and certain of his successors and affiliates are also excluded from the
definition of "Adverse Person."
    
 
                                       53
<PAGE>   56
 
     The Rights will not be exercisable until the Distribution Date and will
expire at the close of business on             , 2008, unless earlier redeemed
by the Company as described below.
 
     As soon as practicable after the Distribution Date, Rights certificates
will be mailed to holders of record of the Common Stock as of the Distribution
Date and, thereafter, the separate Rights Certificates alone will represent the
Rights. Except as otherwise determined by the Board of Directors, only shares of
Common Stock outstanding prior to the Distribution Date will be issued with
Rights.
 
   
     In the event that (i) the Company is the surviving corporation in a merger
or combination with any Acquiring Person or any Adverse Person, or any Associate
or Affiliate (as defined in the Rights Plan) of any Acquiring Person or Adverse
Person, and its Common Stock remains outstanding, (ii) any Acquiring Person or
any Adverse Person, or any Associate or Affiliate of any Acquiring Person or
Adverse Person, engages in one or more "self-dealing" transactions as set forth
in the Rights Agreement, (iii) an Acquiring Person becomes the Beneficial Owner
of 20% or more of the then outstanding shares of Common Stock or 20% or more of
the Outstanding Shares of Class A Common Stock, (iv) during such time as there
is an Acquiring Person or Adverse Person an event occurs that results in such
Acquiring Person's or Adverse Person's ownership interest being increased by
more than 1% (e.g., a reverse stock split or recapitalization), or (v) the Board
of Directors determines that a person is an Adverse Person, each holder of a
Class A Right will thereafter have the right to receive, upon exercise, Class A
Common Stock (or, in certain circumstances, cash, property, or other securities
of the Company) and each holder of a Class B Right will thereafter have the
right to receive, upon exercise, Class B Common Stock (or, in certain
circumstances, cash, property or other securities of the Company), having a
value equal to two times the Exercise Price of the Right. The Exercise Price is
the Purchase Price multiplied by the number of shares of Common Stock associated
with each Right (initially, one). Notwithstanding any of the foregoing,
following the occurrence of any of the events set forth in clauses (i) through
(v) of this paragraph (the "Flip-In Events"), all Rights that are, or (under
certain circumstances specified in the Rights Agreement) were, beneficially
owned by any Acquiring Person or any Adverse Person, or an Associate or
Affiliate of any Acquiring Person or Adverse Person, will be null and void.
However, a holder cannot exercise the Rights following the occurrence of any of
the Flip-In Events until the termination of the Company's redemption rights set
forth below.
    
 
   
     For example, at an exercise price of $          per Right, each Right not
owned by an Acquiring Person or an Adverse Person (or by certain related
parties) following an event set forth in the preceding paragraph would entitle
its holder to purchase Common Stock with a value of $          (or other
consideration, as noted above) for $          . Assuming that the Common Stock
had a per share value of $          at such time, the holder of each valid Right
would be entitled to purchase 2.0 shares of Common Stock for $          .
Alternatively, the Company could permit the holder to surrender each Right in
exchange for stock cash or other property equivalent to one share of Common
Stock (with a value of $          ) without the payment of any consideration
other than the surrender of the Right.
    
 
   
     In the event that following the Stock Acquisition Date or the date a person
becomes an Adverse Person, (i) the Company is acquired in a merger or
consolidation in which the Company is not the surviving corporation or (ii) 50%
or more of the Company's assets or earning power is sold or transferred, each
holder of a Right (except Rights which have previously been voided as set forth
above) will thereafter have the right to receive, upon exercise of the Right,
common stock of the acquiring company having a value equal to twice the Exercise
Price of the Right.
    
 
   
     The Purchase Price payable, and the number of units of Preferred Stock or
other securities or property issuable, upon exercise of the Rights will be
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) if holders of the Preferred Stock are granted certain
rights or warrants to subscribe for Preferred Stock or securities convertible
into Preferred Stock at less than the current market price of the Preferred
Stock, or (iii) upon the distribution to holders of the Preferred Stock of
evidences of indebtedness or assets (excluding regular quarterly cash dividends)
or of subscription rights or warrants (other than those referred to above).
    
 
   
     With certain exceptions, no adjustments in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. No fractional units will be issued and, in lieu thereof,
    
                                       54
<PAGE>   57
 
an adjustment in cash will be made based on the market price of the Preferred
Stock on the last trading day prior to the day of exercise.
 
   
     At any time until the close of business on the tenth day following the
Stock Acquisition Date, the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right. The ten day redemption period may be
extended by the Board of Directors so long as the Rights are still redeemable.
Immediately upon the action of the Board of Directors ordering redemption of the
Rights, the Rights will terminate and the only right of the holders of Rights
will be to receive the $.01 redemption price.
    
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Common Stock (or other consideration) of the Company as set
forth above.
 
   
     Any of the provisions of the Rights Agreement may be amended by the Board
of Directors of the Company prior to the Distribution Date. After the
Distribution Date, the provisions of the Rights Agreement may be amended by the
Board in order to cure any ambiguity, to make changes which do not adversely
affect the interests of holders of Rights (excluding the interest of any
Acquiring Person or any Adverse Person), or to shorten or lengthen any time
period under the Rights Agreement; provided that no amendment to adjust the time
period governing redemption will be made at a time when the Rights are not
redeemable.
    
 
     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
in certain circumstances. Accordingly, the existence of the Rights may deter
certain acquirors from making takeover proposals or tender offers.
 
  Charter and Bylaw Provisions
 
   
     Prior to this offering, the Company amended its Certificate of
Incorporation and Bylaws to add several provisions that could have the effect of
delaying, deterring, or preventing the acquisition of control of the Company by
means of tender offer, open market purchases, proxy contest or otherwise. Set
forth below is a description of those provisions.
    
 
     Special Meetings of Stockholders. The Company's Bylaws provide that special
meetings of stockholders may be called only by the Chairman of the Board or the
President, or by the Chairman of the Board, President, or the Secretary at the
request in writing of a majority of the Board of Directors. Stockholders are not
permitted to call a special meeting or to require that the Board of Directors
call a special meeting unless authorized by the Board of Directors. The business
permitted to be conducted at such meetings is limited to that brought before the
meetings by or at the direction of the Board of Directors. This provision in the
Bylaws provides for the orderly conduct of all Company affairs at special
meetings of stockholders. Accordingly, a stockholder could not force stockholder
consideration of a proposal over the opposition of the Board of Directors by
calling a special meeting of stockholders prior to the next annual meeting or
prior to such time that the Board of Directors believes such consideration to be
appropriate. This change limits a potential acquiror's ability to choose an
advantageous time to launch a takeover bid.
 
     Advance Notice Requirements for Stockholder Proposals and Director
Nominations. The Bylaws establish advance notice procedures for stockholder
proposals and the nomination, other than by or at the direction of the Board of
Directors or a committee thereof, of candidates for election of directors. These
procedures provide that notice of stockholder proposals and stockholder
nominations for the election of directors at an annual meeting must be in
writing and received by the Secretary of the Company no less than 60 days nor
more than 90 days prior to the annual meeting; provided, however, that in the
event that less than 70 days' notice or prior public disclosure of the date of
the annual meeting is given or made to stockholders, notice by a stockholder, to
be timely, must be received no later than the close of business on the tenth day
following the date on which such notice of the date of the annual meeting was
made or such public disclosure was made, whichever first occurs. The notice of
stockholder nominations must set forth certain information with respect to each
nominee who is not an incumbent director. Other stockholder proposals must also
set
 
                                       55
<PAGE>   58
 
forth certain information about such proposal and about the stockholder who
proposes to bring the proposal before the meeting. These Bylaw provisions do not
give the Board of Directors any power to approve or disapprove stockholder
nominees for director or stockholder proposals. These provisions may have the
effect of (i) precluding or obstructing the inclusion of stockholder proposals
or stockholder nominees for director by requiring stockholders to act well in
advance of a particular meeting and to comply with specific procedures in order
to submit such proposals or nominees at that meeting and (ii) discouraging a
stockholder from soliciting proxies to elect its own slate of directors or
otherwise attempting to obtain control of the Company through shareholder
action, even if such proxy solicitation or attempt might be beneficial to the
Company and its stockholders.
 
     No Action by Stockholder Consent. The Company's Certificate of
Incorporation and Bylaws provide that actions required or permitted to be taken
at any annual or special meeting of the stockholders may, unless authorized by
the Board of Directors, be taken only upon the vote of the stockholders at a
meeting duly called and may not be taken by written consent of the stockholders.
This provision increases the opportunity of all stockholders to participate in
voting on any proposed action and prevents the holders of the requisite voting
power of the Company from using the written consent procedure to take
stockholder action without a meeting. This provision eliminates the ability of
the Company's stockholders to act by written consent in lieu of a meeting
without the approval of the Board of Directors. This provision may effectively
deter or delay certain actions by a person or a group acquiring a substantial
percentage of the Company's stock, even though such actions might be desired by,
or be beneficial to, the holders of a majority of the Company's stock.
 
     Amendments to the Bylaws. The Bylaws provide that any amendment to the
Bylaws requires the affirmative vote of 80% of the outstanding shares of Common
Stock entitled to vote to adopt, amend, or repeal the Bylaws. This
super-majority vote requirement promotes stability for the Company's internal
operating procedures, thereby helping the Company to attain its long term goals
and manage its corporate affairs. This provision makes it more difficult for
stockholders to change the internal operating procedures of the Company, which
may further discourage potentially unfriendly bids for shares of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
     ChaseMellon Shareholder Services has been appointed as the transfer agent
and registrar for the Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     There was no public market for the Common Stock before this offering.
Future sales of substantial amounts of Common Stock in the public market, or the
perception that such sales could occur, could adversely affect the prevailing
market price for the Common Stock. After this offering is completed, the number
of shares available for future sale into the public markets will be restricted
by legal and contractual restrictions, certain of which are described below. The
lapsing of these restrictions will permit sales of substantial amounts of Common
Stock in the public market or could create the perception that such sales could
occur, which could adversely affect the prevailing market price for the Common
Stock.
 
   
     As of September 30, 1998, (i) approximately 38,447,277 shares of Class A
Common Stock were issued and outstanding; (ii) 19,838,757 shares of Class A
Common Stock were subject to issuance on exercise of outstanding options; (iii)
467,160 shares of Class B Common Stock were issued and outstanding; and (iv)
3,200,000 shares of Class B Common Stock were subject to issuance on exercise of
outstanding options. Each share of Class B Common Stock is convertible into one
share Class A Common Stock for purposes of sale of such share of Class B Common
Stock. See "Description of Capital Stock -- Class B Common Stock." The ability
of the holders of options to sell or otherwise transfer shares of Common Stock
is subject to restrictions under their option agreements. Subsequent to
September 30, 1998, an additional 106,400 shares of Class A Common Stock have
become subject to issuance on exercise of outstanding options.
    
 
     The      shares of Class A Common Stock being offered by this Prospectus
may be freely sold in the public market without restriction under the Securities
Act, except for shares purchased by "affiliates" of the Company within the
meaning of Rule 144 under the Securities Act. The remaining shares of Common
Stock may be resold after termination of certain contractual restrictions, in
transactions exempt from the registration requirements of the Securities Act
(pursuant to Rule 144 or Rule 701 under the Securities Act or otherwise) or
pursuant to a registration statement filed under the Securities Act covering the
sale of such securities. In connection with this offering, all holders of
registration rights have agreed not to exercise such rights until at least 180
days after the date of this Prospectus.
 
     Holders of more than      % of the outstanding Common Stock and      % of
the outstanding options to purchase Common Stock have executed lock-up
agreements (the "Lock-Up Agreements"). The Lock-Up Agreements provide that,
without the prior written consent of Morgan Stanley & Co. Incorporated on behalf
of the Underwriters, and the Company, the persons executing the Lock-Up
Agreements will not, until at least 180 days after the date of this Prospectus,
transfer or sell any shares of Common Stock covered thereby, and, in a
substantial majority of cases, that they will not (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, lend, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock, (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 Common Stock, whether any such transaction described in clause (i) or (ii)
above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise for a period ending 180 days after the date of this Prospectus
without the prior written consent of Morgan Stanley & Co. Incorporated and the
Company. The foregoing restrictions do not apply to (a) transfers of shares of
Common Stock or other securities acquired in open market transactions after the
completion of this offering or (b) the sale to the Company of a number of shares
necessary to satisfy any obligation to pay or to withhold taxes that arises as
the result of the exercise of any option to purchase shares granted pursuant to
the Company's 1991 Stock Option Plan. In certain cases, the Lock-Up Agreements
also restrict the transfer of shares of Common Stock following such 180 day
period without the consent of the Company for certain periods of time.
 
     Rule 144 under the Securities Act is a non-exclusive exemption from the
registration requirements of the Securities Act. In general, under Rule 144 as
currently in effect, a person (or persons whose shares are aggregated),
including an affiliate, who has beneficially owned "restricted securities" for
at least one year would be entitled to sell within any three-month period a
number of shares that does not exceed the greater of (i) 1% of the number of
shares of Common stock then outstanding (which will equal        shares
immediately after this offering) or (ii) the average weekly trading volume of
the Common stock on the New
 
                                       57
<PAGE>   60
 
York Stock Exchange during the four calendar weeks preceding the filing of a
notice on form 144 with respect to such sale with the Commission. Sales under
Rule 144 are also subject to certain other requirements regarding the manner of
sale, notice, and availability of current public information about the Company.
 
     Under Rule 144(k), a person who is not deemed to have been an affiliate of
the Company at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years
(including the holding period of any prior owner except an affiliate), is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation, or notice provisions of Rule 144.
 
   
     The holding periods referred to above do not commence to run until the full
purchase price for the Common Stock has been paid in full to the Company.
Subject to the Lock-Up Agreements and the contractual restrictions set forth in
the agreements granting stock options or restricted stock, the Company believes
that substantially all outstanding shares of Common Stock held by persons other
than HWGA may be freely sold without regard to the volume limitations and other
requirements regarding manner of sale, notice, and availability of public
information.
    
 
   
     The Company has filed and the Commission has declared effective a
registration statement on Form S-8 covering all shares of Common Stock issued or
issuable since June 30, 1997 under the terms of the Company's 1991 Stock Option
Plan, Restricted Stock Plan, 1996 Advisor and Consultant Stock Option/Restricted
Stock Incentive Plan, and the Advisor Stock Option/Restricted Stock Incentive
Plan and 400,000 shares of Common Stock that are issuable pursuant to the 1996
Non-Employee Director Stock Option/Restricted Stock Incentive Plan. Subject to
the terms of the Lock-Up Agreements and the terms of the options granted under
these plans, the shares of Common Stock registered on this registration
statement may, subject to the Rule 144 volume limitations described above
applicable to affiliates of the Company, be resold in the public market without
restriction.
    
 
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
                         FOR NON-UNITED STATES HOLDERS
 
   
     The following is a general discussion of certain United States Federal
income and estate tax considerations with respect to the ownership and
disposition of Common Stock applicable to Non-U.S. Holders. In general, a
"Non-U.S. Holder" is any holder other than (i) a citizen or resident of the
United States; (ii) a corporation created or organized in the United States or
under the laws of the United States or of any state; (iii) an estate, the income
of which is includable in gross income for United States federal income tax
purposes regardless of its source; or (iv) a trust if (a) a court within the
United States is able to exercise primary supervision over the administration of
the trust and (b) one or more United States persons have the authority to
control all substantial decisions of the trust. This discussion is based on
current provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), Treasury Regulations promulgated thereunder, judicial opinions,
published positions of the Internal Revenue Service (the "IRS"), and all other
applicable authorities, all of which are subject to change (possibly with
retroactive effect). This discussion does not address all aspects of income and
estate taxation or any aspects of state, local or non-United States taxes, nor
does it consider any specific facts or circumstances that may apply to a
particular Non-U.S. Holder that may be subject to special treatment under the
United States federal income tax laws (such as insurance companies, tax-exempt
organizations, financial institutions, brokers, dealers in securities, and
certain U.S. expatriates). ACCORDINGLY, PROSPECTIVE INVESTORS ARE URGED TO
CONSULT THEIR TAX ADVISORS REGARDING THE UNITED STATES FEDERAL, STATE, LOCAL,
AND NON-UNITED STATES INCOME AND OTHER TAX CONSIDERATIONS OF ACQUIRING, HOLDING
AND DISPOSING OF SHARES OF COMMON STOCK.
    
 
DIVIDENDS
 
     In general, dividends paid to a Non-U.S. Holder will be subject to United
States withholding tax at a 30% rate of the gross amount (or a lower rate
prescribed by an applicable income tax treaty) unless the dividends are
effectively connected with a trade or business carried on by the Non-U.S. Holder
within the United States.
                                       58
<PAGE>   61
 
Dividends effectively connected with such a United States trade or business
generally will not be subject to United States withholding tax if the Non-U.S.
Holder files certain forms, including IRS Form 4224 (or any successor form),
with the payor of the dividend, and generally will be subject to United States
federal income tax on a net income basis, in the same manner as if the Non-U.S.
Holder were a resident of the United States. A Non-U.S. Holder that is a
corporation may be subject to an additional branch profits tax at a rate of 30%
(or such lower rate as may be specified by an applicable income tax treaty) on
the repatriation from the United States of its "effectively connected earnings
and profits," subject to certain adjustments. To determine the applicability of
a tax treaty providing for a lower rate of withholding under the currently
effective Treasury Regulations (the "Current Regulations") and published IRS
positions, dividends paid to an address in a foreign country are presumed to be
paid to a resident of that country absent knowledge to the contrary. Under
Treasury Regulations issued on October 6, 1997 (the "Final Regulations"),
generally effective for payments made after December 31, 1999, a Non-U.S. Holder
(including, in certain cases of Non-U.S. Holders that are entities, the owner or
owners of such entities) will be required to satisfy certain certification
requirements in order to claim a reduced rate of withholding pursuant to an
applicable income tax treaty.
 
GAIN OR SALE OR OTHER DISPOSITION OF COMMON STOCK
 
   
     In general, a Non-U.S. Holder will not be subject to United States federal
income tax on any gain realized upon the sale or other disposition of such
holder's shares of Common Stock unless (i) the gain is effectively connected
with a trade or business carried on by the Non-U.S. Holder within the United
States (in which case the branch profits tax discussed above may also apply if
the Non-U.S. Holder is a corporation); (ii) the Non-U.S. Holder is an individual
who holds shares of Common Stock as a capital asset and is present in the United
States for 183 days or more in the taxable year of disposition and certain other
tests are met; (iii) the Non-U.S. Holder is subject to tax pursuant to the
provisions of the Code regarding the taxation of U.S. expatriates or (iv) the
Company is or has been a United States real property holding corporation (a
"USRPHC") for United States Federal income tax purposes (which the Company does
not believe that it has been, currently is, or will become) at any time within
the shorter of the five-year period preceding such disposition and such Non-U.S.
Holder's holding period. If the Company were or were to become a USRPHC at any
time during this period, gains realized upon a disposition of Common Stock by a
Non-U.S. Holder that did not directly or indirectly own more than 5% of the
Common Stock during this period generally would not be subject to United States
Federal income tax, provided that the Common Stock is "regularly traded on an
established securities market (within the meaning of Section 897(c)(3) of the
Code)."
    
 
ESTATE TAX
 
     Common Stock owned or treated as owned by an individual who is not a
citizen or resident (as defined for United States Federal estate tax purposes)
of the United States at the time of death will be includable in the individual's
gross estate for United States Federal estate tax purposes unless an applicable
estate tax treaty provides otherwise, and therefore may be subject to United
States Federal estate tax.
 
BACKUP WITHHOLDING, INFORMATION REPORTING, AND OTHER REPORTING REQUIREMENTS
 
     The Company must report annually to the Internal Revenue Service and to
each Non-U.S. Holder the amount of dividends paid to, and the tax withheld with
respect to, each Non-U.S. Holder. These reporting requirements apply regardless
of whether withholding was reduced or eliminated by an applicable tax treaty.
Copies of this information also may be made available under the provisions of a
specific treaty or agreement with the tax authorities in the country in which
the Non-U.S. Holder resides or is established.
 
     Under the Current Regulations, United States backup withholding tax (which
generally is imposed at the rate of 31% on certain payments to persons that fail
to furnish the information required under the United States information
reporting requirements) and information reporting requirements (other than those
discussed above under "Dividends") generally will not apply to dividends paid on
Common Stock to a Non-U.S. holder at an address outside the United States.
Backup withholding and information reporting generally will apply, however, to
dividends paid on shares of Common Stock to a Non-U.S. Holder at an
 
                                       59
<PAGE>   62
 
address in the United States, if such holder fails to establish an exemption or
to provide certain other information to the payor.
 
     Under the Current Regulations, the payment of proceeds from the disposition
of Common Stock to or through a United States office of a broker will be subject
to information reporting and backup withholding unless the beneficial owner,
under penalties of perjury, certifies, among other things, its status as a Non-
U.S. Holder or otherwise establishes an exemption. The payment of proceeds from
the disposition of Common Stock to or through a non-U.S. office of a broker
generally will not be subject to backup withholding and information reporting
except as noted below. In the case of proceeds from a disposition of Common
Stock paid to or through a non-U.S. office of a broker that is (i) a United
States person; (ii) a "controlled foreign corporation" for United States Federal
income tax purposes; or (iii) a foreign person 50% or more of whose gross income
from certain periods is effectively connected with a United States trade or
business, information reporting (but not backup withholding) will apply unless
the broker has documentary evidence in its files that the owner is a Non-U.S.
Holder and certain other conditions are satisfied, or the beneficial owner
otherwise establishes an exemption, (and the broker has no actual knowledge to
the contrary).
 
     Under the Final Regulations, the payment of dividends or the payment of
proceeds from the disposition of Common Stock to a Non-U.S. Holder may be
subject to information reporting and backup withholding unless such recipient
satisfies applicable certification requirements or otherwise establishes an
exemption.
 
     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a Non-U.S. Holder can be refunded or
credited against the Non-U.S. Holder's United States Federal income tax
liability, if any, provided that the required information is furnished to the
Internal Revenue Service in a timely manner.

     The U.S. Underwriters and the International Underwriters, and the U.S.
Representatives and the International Representatives, are collectively referred

Underwriting Agreement provides that the obligations of the several Underwriters

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.

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)

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

     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 of any Shares

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(e) 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,
                                       62
<PAGE>   65
 
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 other 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.
 
   
     The Company plans to apply for the listing of the Class A Common Stock on
the New York Stock Exchange.
    
 
     At the request of the Company, the Underwriters have reserved for sale, at
the initial public offering price, up to      shares of the Class A Common Stock
for directors, officers, employees, business associates, and related persons of
the Company. The number of shares of Class A Common Stock available for sale to
the general public will be reduced to the extent such persons purchase such
reserved shares. Any reserved shares that are not so purchased will be offered
by the Underwriters to the general public on the same basis as the other shares
offered hereby.
 
     Each of the Company and the directors, executive officers and certain other
stockholders of the Company has agreed that, without the prior written consent
of Morgan Stanley & Co. Incorporated on behalf of the Underwriters, and the
Company, 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, lend, or otherwise transfer 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 the 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 or the sale to the Company of a number of shares
necessary to satisfy any obligation to pay or to withhold taxes that arises as
the result of the exercise of any option to purchase shares granted pursuant to
the Company's 1991 Stock Option Plan. See "Shares Eligible for Future Sale."

<PAGE>   66
 
     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.
 
     Warburg Dillon Read LLC is a subsidiary of UBS AG, the Company's largest
customer. See "Business -- UBS Agreements."
 
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 and 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
 
     The validity of the Class A Common Stock will be passed upon for the
Company by Hughes & Luce, L.L.P., Dallas, Texas. Certain legal matters relating
to the offering of Class A Common Stock will be passed upon for the Underwriters
by Davis Polk & Wardwell, New York, New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of
Perot Systems Corporation:
 
     We have audited the accompanying consolidated balance sheets of Perot
Systems Corporation and Subsidiaries (the "Company") as of December 31, 1997 and
1996, and the related consolidated statements of operations, changes in
stockholders' equity and cash flows for each of the three years in the 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 consolidated financial position of Perot Systems
Corporation and Subsidiaries as of December 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                             (DOLLARS IN THOUSANDS)
 
1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Perot Systems Corporation (the "Company") was originally incorporated in
the state of Texas in 1988 and on December 19, 1995, the Company reincorporated
in the state of Delaware. The Company provides industry-specific business
solutions and information technology services to clients on a worldwide basis.
The significant accounting policies of the Company are described below. Dollar
amounts presented are in thousands, except as otherwise noted.
 
  Principles of consolidation
 
     The consolidated financial statements include the accounts of the Company
and all domestic and foreign subsidiaries that are more than 50% owned and
controlled. All significant intercompany balances and transactions have been
eliminated.
 
     The Company's investments in 20% to 50% owned companies in which it has the
ability to exercise significant influence over operating and financial policies
are accounted for by the equity method. Accordingly, the Company's share of the
earnings (losses) of these companies is included in consolidated net income.
Investments in unconsolidated companies and limited partnerships that are less
than 20% owned, where the Company has virtually no influence over operating and
financial policies, are carried at cost. The Company periodically evaluates
whether impairment losses must be recorded on each investment by comparing the
projection of the undiscounted future operating cash flows to the carrying
amount of the investment. If this evaluation indicates that future undiscounted
operating cash flows are less than the carrying amount of the investments, the
underlying assets are written down by charges to expense so the carrying amount
equals the future discounted cash flows.
 
  Interim financial information
 
   
     The consolidated financial statements and following notes, insofar as they
are applicable to the nine-months ended September 30, 1998 and 1997 and
transactions subsequent to March 25, 1998, the date of the Report of Independent
Accountants, are not covered by the Report of Independent Accountants. In the
opinion of management, all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the financial position,
results of operations and cash flows for the interim periods presented have been
made. Operating results for the nine months ended September 30, 1998, are not
necessarily indicative of the results for the year ended December 31, 1998.
    
 
  Use of estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expense during the reporting
period. These estimates involve judgments with respect to, among other things,
various future economic factors which are difficult to predict and are beyond
the control of the Company. Therefore, actual amounts could differ from these
estimates.
 
  Cash equivalents
 
     All highly liquid investments with original maturities of three months or
less are considered to be cash equivalents.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                             (DOLLARS IN THOUSANDS)
 
  Revenue recognition
 
     The Company provides services under level-of-effort, fixed-price, and
unit-price contracts, with the length of existing contracts ranging up to 12
years. Revenue from level-of-effort pricing is based on time and materials,
direct costs plus an administrative fee (which may be either a fixed amount or a
percentage of direct costs incurred), or a combination of these methods and may
be based on a set fee for a specified level of resources that is adjusted for
incremental resource usage. Revenue from fixed-price contracts is recognized on
the percentage-of-completion method, and is earned based on the percentage
relationship of incurred contract costs to date to total estimated contract
costs, after giving effect to the most recent estimates of total cost.
Provisions for estimated losses, if any, are made in the period in which the
loss first becomes probable and reasonably estimable. Revenue from unit-price
contracts is recognized based on technology units utilized or by number of
transactions processed during a given period. For unit-price contracts, the
Company establishes a per-unit fee based on the cost structure associated with
the delivery of that unit of service, after an appropriate risk factor is
applied.
 
   
     Year 2000 engagements do not comprise a substantial portion of the
Company's business. For two Year 2000 projects, the Company uses a zero estimate
of profit with equal amounts of revenue and cost recognized until the final
outcome of the engagement can be estimated more precisely because of the
inherent uncertainties regarding testability in the existing system environment
and client acceptance.
    
 
     Billings for products or services for which the Company acts as an agent on
behalf of the client and bears no risk of non-performance, are excluded from the
Company's revenue, except to the extent of any mark-up added.
 
     Deferred revenue is comprised of payments from clients for which services
have not yet been performed, or prepayments against development work in process.
These unearned revenues are deferred and recognized as future contract costs are
incurred and contract services are rendered.
 
  Research and development costs
 
   
     Research and development costs are charged to expense as incurred and were
$653 and $2,993 for the nine months ended September 30, 1998 and 1997,
respectively, and $3,243 and $4,486 for the years ended December 31, 1997 and
1996, respectively. The write-off of purchased research and development costs
made up $2,000 and $3,948 of the total in 1997 and 1996, respectively.
    
 
  Property and equipment
 
     Property and equipment are stated at cost. Property and equipment under
capital leases are recorded at the lower of their fair market value or the
present value of future minimum lease payments determined at the inception of
the lease.
 
     Depreciation and amortization are calculated on a straight-line basis,
using estimated useful lives of two to seven years. Leasehold improvements are
amortized over the shorter of the lease term or the estimated useful life of the
improvement. Property and equipment recorded under capital leases are amortized
on a straight-line basis over the lease term.
 
     Upon sale or retirement of property and equipment, the costs and related
accumulated depreciation are eliminated from the accounts, and any gain or loss
on such disposition is reflected in the consolidated statement of operations.
Expenditures for repairs and maintenance are charged to operations as incurred.

  Software, goodwill and other intangibles
 
   
     Software purchased by the Company and utilized in providing contract
services is capitalized at cost and amortized on a straight-line basis over the
lesser of three to five years and the term of the related contract.
    
 
     The cost of acquired entities is allocated first to identifiable assets
based on estimated fair values. The excess of the 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 estimated productive
life of the assets acquired. Due to the fact that acquired skills and
technological advantages are subject to rapid obsolescence, and thus continuous
reinvestment, the Company's general policy is to amortize goodwill over a three
to ten year period.
 
     The Company periodically evaluates the carrying amount of software,
goodwill, other intangibles and other long-lived assets, as well as the related
amortization periods, to determine whether adjustments to these amounts or
useful lives are required based on current events and circumstances. The
evaluation is based on the Company's projection of the undiscounted future
operating cash flows of the acquired operation over the remaining useful lives
of the related intangible assets. To the extent such projections indicate that
future undiscounted cash flows are not sufficient to recover the carrying
amounts of related intangibles, the underlying assets are reduced by charges to
expense so that the carrying amount is equal to future discounted cash flows.
 
  Income taxes
 
     The Company uses the liability method to compute the income tax provision.
Under this method, deferred income taxes are determined based on the difference
between the financial statement and tax basis of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to reverse. Valuation allowances are established when necessary to reduce
deferred tax assets to the amounts expected to be realized. Income tax expense
consists of the Company's current provision for federal and state income taxes
and the change in the Company's deferred income tax assets and liabilities.
 
   
     The Company does not provide for foreign withholding and income taxes on
the undistributed earnings amounting to $67,168 at September 30, 1998 and
$47,033 at December 31, 1997, cumulatively, for its foreign subsidiaries, as
such earnings are intended to be permanently invested in those operations. The
ultimate tax liability related to repatriation of such earnings is dependent
upon future tax planning opportunities and is not estimable at the present time.
    
 
  Foreign operations
 
   
     The consolidated balance sheets include foreign assets and liabilities of
$137,106 and $93,956 as of September 30, 1998, $95,600 and $73,490,
respectively, as of December 31, 1997, and $101,481 and $77,914, respectively,
as of December 31, 1996.
    
 
     Assets and liabilities of subsidiaries located outside the United States
are translated into U.S. dollars at current exchange rates as of the balance
sheet date, and revenue and expenses are translated at average exchange rates
during each reporting period. Translation gains and losses are recorded as a
separate component of stockholders' equity.
 
     The Company periodically enters into foreign exchange forward contracts to
hedge certain foreign currency transactions for periods consistent with the
terms of the underlying transactions. The forward exchange contracts generally
have maturities that do not exceed one year.

                             (DOLLARS IN THOUSANDS)
 
   
     The net foreign currency transaction gains/(losses) reflected in other
income/(expense) were $(70) and $715 for the nine months ended September 30,
1998 and 1997; $736, ($1,715) and ($892) for the years ended December 31, 1997,
1996 and 1995, respectively.
    
 
  Concentrations of credit risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist of cash equivalents and accounts
receivable. The Company's cash equivalents consist primarily of short-term money
market deposits. The Company has deposited its cash equivalents with reputable
financial institutions, from which the Company believes the risk of loss to be
remote. The Company has accounts receivable from its customers who are engaged
in the banking, insurance, healthcare, manufacturing, communications, travel and
energy industries, and are not concentrated in any specific geographic region.
These specific industries may be affected by economic factors, and, therefore,
accounts receivable may be impacted. Generally, the Company does not require
collateral from its customers, since the receivables are supported by long-term
contracts. Management does not believe that any single customer, industry or
geographic area represents significant credit risk.
 
   
     Two customers accounted for 13% and 12% of the Company's accounts
receivables for the nine months ended September 30, 1998. One customer accounted
for 11% and 27% of the Company's accounts receivables at December 31, 1997 and
1996, respectively.
    
 
  Financial instruments
 
     The fair value of the Company's financial instruments is estimated using
bank or market quotes or discounted cash flows at year-end foreign exchange and
interest rates. The fair value of the financial instruments is disclosed in the
relevant notes to the financial statements. The carrying amount of short-term
financial instruments (cash and cash equivalents, accounts receivable, and
certain other liabilities) approximates fair value due to the short maturity of
those instruments.
 
     The Company uses derivative financial instruments for the purpose of
hedging specific exposures as part of its risk management program and holds all
derivatives for purposes other than trading. Deferral (hedge) accounting is
applied only if the derivative reduces the risk of the underlying hedged item
and is designated at inception as a hedge with respect to the underlying hedged
item. Additionally, the derivative must result in cash flows that are expected
to be inversely correlated to those of the underlying hedged item. Such
instruments to date have been limited to interest rate swap and foreign currency
exchange forward contracts.
 
  Treasury stock

     In June 1997, the Financial Accounting Standard Board ("FASB") issued SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("Statement 131") effective for years beginning after December 15, 1997.
Statement 131 requires that a public company report financial and descriptive
information about its reportable operating segments pursuant to criteria that
differ from current accounting practice. Operating segments, as defined, are
components of an enterprise about which separate financial information is
available that is evaluated regularly by the management in deciding how to
allocate resources and in assessing performance. The financial information to be
reported includes segment profit or loss, certain revenue and expense items and
segment assets and reconciliations to corresponding amounts in the financial
statements. Statement 131 also requires information about revenues from products
or services, countries where the company has operations or assets and major
customers. Management does not believe the implementation of Statement 131 will
have a material impact on its consolidated financial statements.
 
   
     In June 1998, the FASB issued SFAS No. 133 which establishes accounting and
reporting standards for derivative instruments and for hedging activities. The
Statement requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet at fair value. If certain conditions are met, a
derivative may be specifically designated as a fair value hedge, a cash flow
hedge, or a foreign currency hedge. A specific accounting treatment applies to
each type of hedge. SFAS No. 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. SFAS No. 133 is not expected to have a
material impact on the Company's financial position or results of operations.
    
 
   
     The American Institute of Certified Public Accountants (the "AICPA") issued
Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," in March 1998. SOP 98-1
provides guidance on accounting for the costs of computer software developed or
obtained for internal use and requires costs incurred in the application
development stage (whether internal or external) to be capitalized. This SOP is
applicable to all financial statements for fiscal years beginning after December
15, 1998, and should be applied to internal-use computer software costs incurred
in those fiscal years for all projects, including those projects in progress
upon initial application of this SOP. Costs incurred prior to initial
application of this SOP, whether or not capitalized, should not be adjusted to
the amounts that would have been capitalized had this SOP been in effect when
those costs were incurred. The adoption of this SOP is not expected to have a
material impact on the Company's financial position or results of operations.

</TABLE>
    
 
   
     With regard to amounts billed, allowances for doubtful accounts are
provided based on specific identification where less than full recovery of
accounts receivable is expected. Amounts to be invoiced represent revenue
contractually earned for services performed, which are invoiced to the customer
in the following month. Recoverable costs and profits represent amounts
previously recognized as revenue, that have not yet been billed, in accordance
with the contract terms. In certain cases, the period of recovery may extend
beyond one year. However, classification of these amounts within current assets
has been made in accordance with common industry practice. At December 31, 1997,
it is anticipated that $2,210 of the recoverable costs and profits will be
billed in 1998 and $588 will be billed in 1999. At September 30, 1998, it is
anticipated that $5,143 of the recoverable costs and profits will be billed in
1998, $14,875 will be billed in 1999, and $237 will be billed in 2000.

4. ACQUISITIONS
 
     During 1997, the Company acquired 100% of the equity interests or assets in
four companies: Business Architects, LLP, ("BA"), based in Waltham,
Massachusetts, a business process reengineering consulting company; Benton
International, Inc. ("Benton"), a retail banking consulting firm located in New
York, California and Florida; Syllogic B.V. ("Syllogic"), a company based in The
Netherlands, specializing in the implementation, integration and control of
information systems with expertise in data warehousing and data mining; and
Stamos Associates, Inc. ("Stamos"), based in New York and California, a
strategic management consulting company in the healthcare industry. Also, the
Company acquired 70% of the equity interests in Icarus Consulting AG ("Icarus"),
a company specializing in airline and related industry consulting.
 
     These five acquisitions were recorded under the purchase method of
accounting; and accordingly, the results of operations of these companies for
the periods from the date of the acquisition agreements to December 31, 1997 are
included in the accompanying 1997 consolidated statement of operations. The
dates of the 1997 acquisition agreements for BA, Benton, Icarus, Syllogic, and
Stamos were January 15, February 14, March 21, May 27 and June 17, respectively.
The purchase prices have been allocated to assets acquired and liabilities
assumed based on the estimated fair values at the dates of acquisition.
 
     Under the terms and conditions of the various acquisition agreements
executed in 1997, the Company paid a total of $18,587 for the equity interests
acquired, $14,386 in cash, $2,701 in the form of 370,000 shares of the Company's
Class A Common Stock, and $1,500 in the form of 550,000 options to purchase the
Company's Class A Common Stock. The Company allocated $3,513 of the purchase
price to the tangible net assets acquired and $15,074 to goodwill.
 
     During 1996, the Company acquired all of the equity interests in four
companies: Rothwell International, Inc. ("Rothwell"), based in Houston, Texas,
an object-oriented programming company; Doblin Group, Inc. ("Doblin"), a
Chicago-based consulting company, engaging in strategic design planning and
consulting for breakthrough products and services; CommSys Corporation
("CommSys"), located in Reston, Virginia, a developer of billing systems for
telecommunication companies; and The Technical Resource Connection, Inc.
("TRC"), based in Tampa, Florida, specializing in object-oriented programming
and software development.
 
     These four acquisitions were recorded under the purchase method of
accounting; and accordingly, the results of operations of Rothwell, Doblin,
CommSys, and TRC for the periods from the date of the acquisition agreements to
December 31, 1997 are included in the accompanying 1996 and 1997 consolidated
statements of operations. The dates of the 1996 acquisition agreements for
Rothwell, Doblin, CommSys, and TRC were August 2, September 10, September 16 and
October 25, respectively. The purchase prices have been allocated to assets
acquired and liabilities assumed based on the estimated fair values at the dates
of acquisition. In addition, portions of the purchase price of CommSys and TRC
were allocated to in-process product development that had not reached
technological feasibility and had no probable alternative future uses, which the
Company recorded at the date of acquisition.
 
     Under the terms and conditions of the various acquisition agreements
executed in 1996, the Company paid a total of $16,214 for the equity interests
acquired, $9,669 in cash, and $6,545 in the form of 1,460,372 shares of the
Company's Class A Common Stock. The Company allocated $4,286 of the purchase
price to the tangible net assets acquired, $3,948 to expensed in-process product
development and $7,980 of goodwill.
 
   
     In July 1998, the Company sold its equity interest in Doblin Group, Inc.
Under the terms and conditions of the divestiture agreement, the Company
received $900 in cash, $1,182 in the form of 60,000 shares of the Company's
Class A Common Stock, and a $59 note receivable. The impact of the sale was
immaterial to the results of operations for the nine months ended September 30,
1998.

     The following table reflects unaudited pro forma combined results of
operations of the Company and the 1997 and 1996 acquisitions on the basis that
the acquisitions had taken place and the related product development expense was
recorded at the beginning of the calendar year for each of the periods
presented:

     In management's opinion, the unaudited pro forma combined results of
operations are not indicative of the actual results that would have occurred had
the acquisitions been consummated at the beginning of 1997 and 1996,
respectively, or of future operations of the combined companies under the
ownership and management of the Company.
 
   
     During September 1998, the Company determined that certain amounts recorded
for goodwill primarily from the acquisition of Stamos Associates, Inc.
("Stamos") was impaired and no longer recoverable. The determination was made
based on management's best estimates of the undiscounted future operating cash
flows over the remaining useful life of the goodwill. From this analysis, an
impairment loss was calculated as the difference between the carrying amount of
the goodwill and the fair value of the asset, based on discounted estimated
future cash flows. Goodwill impairments included in the accompanying statement
of operations totaled $3,845 consisting of primarily a write-down of Stamos
goodwill of $3,680. The Stamos goodwill impairment was due primarily to an
expected decline in future cash flows resulting from the departure of certain
key employees during the second and third quarters of 1998. The Company believes
that the remaining Stamos goodwill balance of $338 is recoverable over the
amortization period.
    
 
   
     At September 30, 1998 and December 31, 1997 and 1996, goodwill of $7,240,
$16,596 and $7,293, net of $15,876, $6,309 and $686 in accumulated amortization,
respectively, related solely to 1997 and 1996 business acquisitions.
    
 
5. INVESTMENTS IN UNCONSOLIDATED AFFILIATES AND MINORITY INTERESTS
 
   
     At December 31, 1997, investments in and advances to unconsolidated
affiliates include two equity investments made in 1996. On January 5, 1996, the
Company acquired 40% of the equity interest in Systor AG ("Systor"), a Swiss
information services company, from UBS AG as part of a larger services
agreement. The Company's investment in Systor at September 30, 1998 and at
December 31, 1997 and 1996 was $8,626, $7,188 and $3,538, respectively.
Summarized financial data for Systor is as follows:

technology services company based in India. The Company contributed capital of
$500 and $1,760 to HPS during 1997 and 1996, respectively, and is required to
contribute additional capital up to a limit of $6,900, on a call basis. The
Company's investment in HPS at September 30, 1998 and at December 31, 1997 and
1996 was $3,702, $1,742 and $524, respectively.
    
 
   
     In June 1998, Systor declared a cash dividend. The Company received the 40%
share, or $804, in August 1998. No dividends or distributions were received from
investments in unconsolidated affiliates in 1997 or 1996. The amount of
undistributed earnings from investments in unconsolidated affiliates recorded in
retained earnings at September 30, 1998 and at December 31, 1997 and 1996 was
$8,455, $5,060 and $924, respectively.
    
 
     In April 1996, the Company entered into an agreement to join a limited
partnership venture capital fund, and committed to invest $10,000, representing
a 2.75% interest in the fund. In 1997 and 1996, the Company made net capital
contributions of $834, and $1,292, respectively. In January 1998, the Company
sold its entire investment for $5,162 and recognized a gain of $2,986, and has
no future commitments to the fund.
 
   
     In May 1996, the Company purchased 1,471,000 shares of a class of preferred
stock in a software company for $2,500. The Company purchased an additional
400,000 shares of the preferred stock for $400 in June 1997. Due to certain
anti-dilution provisions, the Company received additional shares bringing the
total number of shares to 2,394,000, representing approximately an 8% equity
interest at September 30, 1998. As part of the purchase agreement, the Company
was subject to a call option, which, if exercised, would require the Company to
purchase additional shares for a commitment of up to $1,000. During the third
quarter of 1998, the Company's commitment terminated.
    
 
     In January 1997, the Company purchased 4,000 shares of 5% cumulative
convertible preferred stock for $1,000, representing a 4.5% interest in a
privately held company specializing in the electronic transmission, storage and
retrieval of documents.
 
     In December 1997, the Company wrote both of these investments down by the
entire book value of $3,900 due to a decline in value considered to be other
than temporary.
 
   
     During the nine months ended September 30, 1998, the Company entered into a
joint venture with the Bank of Ireland whereby the Company owns 49% of Perot
Systems Information Resource (Ireland) Limited, a Dublin-based entity providing
data center and other related services. The Company made a capital contribution
of $344 to the joint venture in July 1998.
    
 
6. OTHER ASSETS
 
  Intellectual property rights
 
     In July 1997, the Company acquired certain assets of Nets, Inc., an
internet development company in bankruptcy, for $8,755 in cash. Included in the
asset purchase were $2,132 of property and equipment and $6,623 of intellectual
property rights ("IP rights"). The Company recorded a write-off of $2,000 of the
$6,623 in IP rights as purchased research and development costs. This amount
represented an estimate of the fair market value of development cost related to
software for which technological feasibility had not been established and for
which there was no alternative future use. The completed IP rights were
capitalized due to the expectation that the assets would be used in several
contracts under negotiation.
 
     During the fourth quarter of 1997, the Company determined that it was not
probable that the Company would generate future undiscounted cash flows
sufficient to recover the recorded value of the IP rights. The Company sold
$1,000 of the intellectual property in October 1997, and charged $3,623 to
direct cost of services to reflect the impairment of the remaining IP rights.

  Software license transfer rights
 
     In July 1996, the Company determined that certain software rights and
assets placed in service in 1993 were impaired due to the market shift from
mainframe systems to client/server and network based systems. In addition, the
Company's business mix had gradually shifted from outsourcing to application
development, systems integration, and consulting. As a result, the $7,552 of
transfer rights and assets in service and the $3,396 of related accumulated
amortization were written off resulting in a loss of $4,156 classified as direct
cost of services.
 
7. LINE OF CREDIT
 
   
     Effective July 31, 1996, the Company established its bank line of credit,
which allows borrowings up to $40,000 at either the adjusted Eurodollar rate
plus 1%, or the bank's prime lending rate. There were no borrowings outstanding
under the line at September 30, 1998 and December 31, 1997. This facility
expired July 31, 1998 and was renewed pursuant to the same terms until January
31, 1999.

  Other contract-related
 
   
     Other contract-related accrued liabilities represent provisions to match
contract-related expenses in the period in which revenues from those contracts
are recognized. These include claims made by customers for services that require
additional effort and costs by the Company to satisfy contractual requirements.
The Company continually monitors contract performance in light of client
expectations, the complexity of work, project plans, delivery schedules, and
other relevant factors. Provisions for estimated losses, if any, are made in the
period in which the loss first becomes probable and reasonably estimable. An
expense of $10,200 was recorded in 1997 to recognize management's estimate of
known future losses associated with the termination or completion of two
long-term contracts. An expense of $13,485 was recorded during the nine months
ended September 30, 1998 to address Year 2000 exposure for certain customer
contracts.

10. STOCKHOLDERS' EQUITY
 
  Preferred stock
 
     At December 31, 1995, the Company had 4,000,000 shares of $2.125 par value
Series A Preferred Stock outstanding. In 1996 the Company exercised its right to
redeem these shares for $8,500 cash, plus accrued dividends of $298. The
authorized preferred stock was subsequently removed from the Company's charter
in 1997.
 
  Common stock and convertible liquidation preference common stock
 
   
     In July 1998, the Board of Directors of the Company approved an amendment
to the Company's Certificate of Incorporation which included an increase in
authorized number of shares of Class A Common Stock to 200,000,000 from
100,000,000 shares. The amendment was approved by stockholders in August 1998.
At September 30, 1998 there were 40,527,321 shares issued and 38,447,277 shares
outstanding. At December 31, 1997 there were 40,524,819 shares issued and
38,227,707 shares outstanding and at December 31, 1996 there were 39,623,848
shares issued and outstanding. The Company is authorized to issue, under its
existing stock plans, up to 42,000,000 shares of Class A Common Stock. At
September 30, 1998 there were 18,021,577 shares outstanding. At December 31,
1997 there were 17,586,207 shares outstanding and at December 31, 1996 there
were 17,582,348 shares outstanding.
    
 
   
     Class B shares consist of 24,000,000 authorized shares of $0.01 par value
common stock, of which there are 467,160 shares issued and outstanding as of
September 30, 1998. At December 31, 1997 there were 50,000 shares issued and
outstanding and at December 31, 1996 there were no shares issued and
outstanding. The

Class B shares were authorized in conjunction with the provisions of the
original UBS AG service agreements, which were signed in January 1996. Class B
shares are non-voting and convertible, but otherwise are equivalent to the Class
A shares.
 
     Under the terms and conditions of the UBS AG agreements, each Class B share
shall be converted, at the option of the holder, on a share-for-share basis,
into a fully paid and non-assessable Class A share, upon sale of the share to a
third-party purchaser under one of the following circumstances: 1) in a widely
dispersed offering of the Class A shares; 2) to a purchaser of Class A shares
who prior to the sale holds a majority of the Company's stock; 3) to a purchaser
that after the sale holds less than 2% of the Company's stock; 4) in a
transaction that complies with Rule 144 under the Securities Act of 1933, as
amended; or 5) any sale approved by the Federal Reserve Board of the United
States.
 
     At December 31, 1995, the Company had 16,000,000 shares of $0.01 par value
Convertible Liquidation Preference Common Stock. In 1996, at the initiation of
the holder, and under the terms of the Company's Certificate of Incorporation,
the 16,000,000 outstanding shares of Convertible Liquidation Preference Common
Stock were converted on a one-for-one basis into fully paid and non-assessable
Class A shares. The Convertible Liquidation Preference Common Stock was removed
from the Company's charter in 1997.
 
  Restricted Stock Plan
 
     In 1988, the Company adopted a Restricted Stock Plan, which was amended in
1993, to attract and retain key employees, and to reward outstanding
performance. Employees selected by management may elect to become participants
in the plan by entering into an agreement that provides for vesting of the Class
A shares over a five-to-ten year period and establishes a two-year holding
period on one-half of the shares prior to the sale of vested common stock. Each
participant has voting, dividend and distribution rights with respect to all
shares of both vested and unvested common stock. Prior to the Class A shares
becoming publicly traded, the Company retains the right of first refusal to buy
the employees' vested shares at a formula price set forth in each agreement,
based on fair value or book value. After the Class A shares become publicly
traded, the right of first refusal no longer exists. The Company may repurchase
unvested shares, and under certain circumstances, vested shares of participants
whose employment with the Company terminates. The repurchase price under these
provisions is determined by the underlying agreement, generally the employees'
cost plus interest at 8%. Common stock issued under the Restricted Stock Plan
has been purchased by the employees at varying prices, determined by the Board
of Directors and estimated to be the fair value of the shares based upon an
independent third-party appraisal. The Company has from time to time financed
the issuance of shares under the Restricted Stock Plan by executing promissory
notes with the employees, with repayment terms ranging from one to fifteen
years. These notes bear interest at 8%, payable at least annually, and are with
recourse. Principal and interest payments vary from monthly to 5 years, and the
loans are collateralized by the shares financed by the notes. The balance of the
outstanding notes is included as a reduction to stockholders' equity.
 
  1991 Stock Option Plan
 
   
     In 1991, the Company adopted the 1991 Stock Option Plan (the "1991 Plan"),
which was amended in 1993 and 1998. Pursuant to the 1991 Plan, options to
purchase the Company's Class A shares can be granted to eligible employees. The
stock options are granted at a price not less than 100% of the fair value of the
Company's Class A shares, as determined by the Board of Directors, based upon an
independent third-party valuation. The stock options vest over a three to ten
year period based on the provisions of each grant, and in some cases can be
accelerated through attainment of financial performance criteria. For options
issued before July, 1998, stock options require a two-year holding period for
one half of the shares purchased once the options are exercised, and are usually
exercisable from the vesting date until the eleventh anniversary from the date
of grant, and unvested options are cancelled following the expiration of a
certain period after the employee leaves the employment of the Company. Prior to
the common stock becoming publicly traded, the

Company has certain rights of first refusal to repurchase employees' shares
obtained through exercise of the stock options at the employees' cost plus 8%.
For options issued after April 1, 1997, the agreements provide that shares
issued upon the exercise of the options may not be sold until six months
following an initial public offering.
 
   
     During the period July 1, 1998 to November 13, 1998, the Company issued
options to associates to acquire Class A shares at an exercise price equal to
the initial public offering price (if this offering is completed by January 20,
1999) or as otherwise determined by the Board of Directors. There were 4,755,580
and 4,861,980 of these options outstanding at September 30, 1998 and November
13, 1998 respectively.
    
 
  Advisor Stock Option/Restricted Stock Incentive Plan
 
     In 1992, the Company adopted the Advisor Stock Option/Restricted Stock
Incentive Plan (the "Advisor Plan"), which was modified in 1993, to enable
non-employee directors and advisors to the Company and consultants under
contract with the Company to acquire shares of the Company's Class A stock, at a
price not less than 100% of the fair value of the Company's common stock, as
determined by the Board of Directors, based upon an independent third-party
valuation. The options and shares are subject to a vesting schedule and
restrictions associated with their transfer. Under certain circumstances, the
shares can be repurchased by the Company at cost plus 8% from the date of
issuance.
 
     In 1996, the Board approved the 1996 Non-Employee Director Stock
Option/Stock Incentive Plan and the 1996 Advisor and Consultant Stock
Option/Stock Incentive Plan, which together replaced the Advisor Plan for
subsequent grants of options. Provisions of the Advisor Plan will remain in
effect for outstanding stock and options but no new issuances will be made
pursuant to the plan.
 
  1996 Non-Employee Director Stock Option/Stock Incentive Plan
 
     In 1996, the Company adopted the 1996 Non-Employee Director Stock
Option/Stock Incentive Plan (the "Director Plan"). The Director Plan provides
for the issuance of up to 400,000 Class A shares or options to Board members who
are not employees of the Company. Shares or options issued under the plan would
be subject to five year vesting, with options expiring after an eleven year
term. The purchase price for shares issued and exercise price for options issued
is the fair value of the shares at the date of issuance. Other restrictions are
established upon issuance. In 1997, 60,000 options were granted under the plan.
 
  1996 Advisor and Consultant Stock Option/Stock Incentive Plan
 
     In 1996, the Company adopted the 1996 Advisor and Consultant Stock
Option/Stock Incentive Plan (the "Consultant Plan"). The Consultant Plan
provides for the issuance of Class A shares or options to advisors or
consultants who are not employees of the Company, subject to restrictions
established at time of issuance. The option exercise price is the fair value of
the shares on the date of grant. The purchase price for share issuances is
determined by a committee appointed by the Board of Directors. The fair value of
issuances under the plan is estimated at the time of issuance and amortized
ratably over the vesting period as compensation expense. In 1997, 24,000 options
were granted under the plan.
 
  Other stock and option activity
 
     During 1995, options for the purchase of 2,000,000 Class A shares, with an
exercise price of $1.00 per share, were granted to an executive officer of the
Company when the fair value of the stock was estimated to be $1.75 per share.
This resulted in deferred compensation of $1,500, which was recorded as a
reduction to stockholders' equity. These options were exercised in 1995, whereby
the Company received cash of $600, and a promissory note for $1,400 in
consideration for the shares, under the terms of the original grant.

     Prior to an underwritten public offering of its common stock, the Company
retains the right of first refusal to buy back the vested shares for cash at a
purchase price equal to fair value, and the unvested shares at the cost paid by
the shareholder. After such an offering, the right of first refusal no longer
exists. The Company had the right, under certain circumstances, to repurchase
certain shares at cost if employment with the Company terminates.
 
   
     During the third quarter of 1997, the executive terminated his employment
and the Company made a non-cash repurchase of 1,400,000 shares of common stock
through a reduction of $1,830 in outstanding notes receivable. The unamortized
balance of deferred compensation was reclassified to additional paid-in capital.
    
 
  UBS AG Agreement
 
     On April 24, 1997, the Company concluded the renegotiation of the terms of
its strategic alliance with UBS AG, initially entered into in January 1996. The
new terms were effective from January 1, 1997 and involve (i) a 10-year contract
for the Company to provide information technology ("IT") services to UBS Warburg
("UBS Warburg EPI Agreement"), (ii) separate agreements to provide IT services
to other UBS AG operating units and to permit the Company to use certain UBS AG
assets, (iii) the sale to UBS AG of options to acquire shares of the Company's
Class B stock, (iv) the sale to UBS AG of shares of the Company's Class B stock,
and (v) the termination of all options to acquire shares of the Company's Class
B stock granted under the terms and conditions of prior UBS AG agreements. The
Company continues to hold a 40% stake in Systor. In the event of termination of
the UBS Warburg EPI Agreement, a portion of the Company's interest in Systor
would be returned to UBS AG, declining ratably over the 10-year period which
began on January 1, 1997.
 
     The new terms of the UBS Warburg EPI Agreement require the Company to
provide operational management for UBS investment banking division, Warburg
Dillon Read, technology resources (including mainframes, desktops, and voice and
data networks), excluding hardware and proprietary software applications
development. The Company is to be reimbursed for all costs, excluding corporate
overhead, related to services provided under the UBS Warburg EPI Agreement. In
addition, the Company will receive a management fee, subject to bonuses and
penalties, depending upon the achievement of certain defined performance
criteria.
 
   
     Under the terms and conditions of the new agreement, the Company sold to
UBS AG options to purchase 3,617,160 shares of the Company's Class B stock at a
non-refundable cash purchase price of $2.25 per option. These Class B shares are
subject to certain transferability and holding-period restrictions, which lapse
over a defined vesting period. These options are exercisable immediately and for
a period of 5 years after the date that such shares become vested, at an
exercise price of $7.30 per share. In addition, the Company sold to UBS AG
50,000 shares of the Company's Class B stock, subject to the same
transferability and holding-period restrictions, at a purchase price of $7.30
per share. These options and shares were sold in connection with the execution
and delivery of the 10-year UBS Warburg EPI Agreement. Both the 50,000 shares of
Class B stock and the 3,617,160 shares of Class B stock subject to options vest
at a rate, in the aggregate, of 31,953 shares per month for the first five years
of the agreement, and at a rate of 29,167 shares per month thereafter. In the
event of termination of the UBS Warburg EPI Agreement, options to acquire
unvested shares would be forfeited, and the Company would have the right to buy
back any previously acquired unvested shares for the original purchase price of
$7.30 per share. UBS AG exercised 417,160 options in the third quarter of 1998.
    
 
     The Company also agreed to issue and sell to UBS AG additional shares
and/or options to purchase Class B shares, subject to the same transferability
and holding-period restrictions, up to a maximum of 3,500,000 shares, in such
combination of options and shares that UBS AG deems appropriate, provided the
Company and UBS AG, on or prior to December 31, 1998, enter into a second IT
services agreement, having a term of 10 years, and being of a size and scope
similar to that of the UBS Warburg EPI Agreement. The

purchase price and exercise price for these options, as well as the purchase
price for these shares will be the defined fair value as of the date of grant.
These shares will vest ratably over 10 years commencing on the date of execution
of the new agreement. In the event of termination, options to acquire unvested
shares would be forfeited, and the Company would be required to buy back any
previously acquired unvested shares for the original purchase price.
 
     Pursuant to the Bank Holding Company Act of 1956 and subsequent regulations
and interpretations by the Federal Reserve Board (the "regulations"), UBS AG's
holdings in terms of shares of the Company's Class B common stock may not exceed
10% of the total of all classes of the Company's common stock. Similarly, the
total consideration paid by UBS AG for the purchase of shares plus the purchase
and exercise of options may not exceed 10% of the Company's consolidated
stockholders' equity as determined in accordance with generally accepted
accounting principles. If, however, on certain specified anniversaries of the
execution date of the new agreement, beginning in 2004, the number of Class B
shares, for which UBS AG's options are exercisable, is limited due to an
insufficient number of shares outstanding, UBS AG has the right to initiate
procedures to eliminate such deficiency. These procedures may involve (i)
issuance of additional Class A shares by the Company, (ii) a formal request to
the Federal Reserve Board from UBS AG for authorization to exceed the 10% limit
on ownership, or (iii) the purchase of Class B shares by the Company from UBS AG
at a defined fair value. In addition, the exercise period for options to
purchase vested shares would be increased beyond the normal 5 years to account
for any time during such exercise period in which UBS AG is unable to exercise
its options as a result of the regulations.
 
  Deferred Compensation
 
   
     The Company recorded $4,027 of deferred compensation expense for options
granted during the nine months ended September 30, 1998 representing the
difference between the option exercise price and the fair value of the
underlying common stock. The Company recognized $271 of compensation expense
during the nine months ended September 30, 1998 and will amortize the remaining
deferred compensation ratably over the respective vesting periods of the option
grants. Prior to any option forfeitures resulting from employee attrition, the
estimated amount of deferred compensation to be recognized during 1998 is $372
and approximately $407 for each year through 2008.

     All options issued by the Company in 1997, 1996 and 1995 were issued at the
estimated fair value in effect at the date of issuance, vest ratably over the
vesting period, and expire one year after the final vesting date. The fair value
of each option grant was estimated on the date of grant using the Minimum Value
option pricing model with the following assumptions for 1997, 1996 and 1995,
respectively; risk free weighted average interest rates of 6.5% for 1997 and
6.8% for 1996 and 1995; dividend yield and volatility of zero for all years. The
expected life for each issuance was equal to the midpoint of the vesting period,
plus one year. For example, an option vesting ratably over ten years has an
expected life of 6 years. The weighted-average grant-date fair value of options
issued in 1997, 1996 and 1995 was $2,709, $5,938 and $1,916, respectively. The
Company expects that the impact of future option issuances will be to increase
overall pro forma compensation expense, thereby reducing pro forma net income
reported in future periods.
 
   
     On August 5, 1998, the Company filed a registration statement with the
Securities and Exchange Commission for an initial public offering of the
Company's Class A Common Stock.
    
 
   
     In July 1998, the Board of Directors adopted an employee stock purchase
plan (the "ESPP"), which provides for the issuance of a maximum of 10,000,000
shares of Class A Common Stock. The ESPP will become effective immediately
following the proposed initial public offering of the Company's Class A

Common Stock. Eligible employees may have up to 10% of their earnings withheld,
to be used to purchase shares of the Company's Common Stock on specified dates
determined by the Board of Directors. The price of the Common Stock purchased
under the ESPP will be equal to 85% of the fair value of the stock on the
exercise date for the offering period.
    
 
   
     The Board of Directors of Perot Systems anticipates authorizing the Company
to enter into a Stockholder Rights Plan (the "Rights Plan"), providing that one
Class A right (a "Class A Right") will be attached to each share of Class A
Common Stock and one Class B right (a "Class B Right", and together with the
Class A Rights, the "Rights") will be attached to each share of Class B Common
Stock as of the record Date to be determined by the Executive Committee of the
Board of Directors (the "Executive Committee"). Each Class A Right will entitle
the registered holder to purchase from the Company a unit consisting of one one-
hundredth of a share of Series A Junior Participating Preferred Stock, par value
$.01 per share (the "Series A Preferred Stock"), at a purchase price to be
determined by the Executive Committee, which price will be subject to
adjustment. Each Class B Right entitles the registered holder to purchase from
the Company a unit consisting of one one-hundredth of a share of Series B Junior
Participating Preferred Stock, par value $.01 per share (the "Series B Preferred
Stock" and, together with the Series A Preferred Stock"), at a purchase price to
be determined by the Executive Committee, which price will be subject to
adjustment. The Rights will not be exercisable until the Distribution Date and
will expire ten years following the adoption of the Rights Plan, unless earlier
redeemed by the Company as described below. At any time until 10 days following
the Stock Acquisition Date, the Company may redeem the Rights in whole, but not
in part, at a price of $.01 per Right. The ten day redemption period may be
extended by the Board of Directors so long as the Rights are still redeemable.
Immediately upon the action of the Board of Directors ordering redemption of the
Rights, the Rights will terminate and the only right of the holders of Rights
will be to receive the $.01 redemption price.
    
 
   
     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
in certain circumstances. Accordingly, the existence of the Rights may deter
certain acquirors from making takeover proposals or tender offers.

     The Company is obligated under certain operating leases for its pro rata
share of the lessors' operating expenses. Rent expense was $18,897 and $12,604
for the nine months ended September 30, 1998 and 1997, and $17,958, $18,212, and
$23,731 for the years ended December 31, 1997, 1996 and 1995, respectively.
Additionally, in 1997, the Company established a loss accrual of $3,125 in
connection with the planned abandonment of certain leased properties. During the
nine months ended September 30, 1998, the Company revised its estimate of that
loss accrual to $5,120.
    
 
  Letter of credit
 
   
     The Company had a $1,000 irrevocable letter of credit as of September 30,
1998. The letter of credit was issued in conjunction with the provisions of a
certain contract. The fair value of the letter of credit was estimated to be
equal to the face value based on the nature of the fee arrangements with the
issuing bank. This letter of credit expires in December 1998 and will not be
renewed.
    
 
  Financial instruments with off-balance sheet risk
 
    Interest rate swap
 
     In December 1993, the Company entered into an agreement with a client to
reduce future monthly billings in exchange for a non-refundable payment for work
performed involving the development and installation of a major new system.
Under the terms of this agreement, the Company was required to make an
interest-sensitive payment to the client if a defined variable interest rate
("Rate") exceeded 8.5% based upon a declining notional amount ($48,756 and
$67,716 as of December 31, 1997 and 1996, respectively) over the term of the
contract. If the Rate was less than 8.5%, the client was required to pay the
Company for the difference in the interest rates based upon the same declining
notional amount.
 
     In January 1994, the Company entered into an interest rate swap agreement
with a bank to eliminate its exposure to the interest sensitive payment. Under
the terms of the swap agreement, the Company was required to pay a fixed
interest rate of 7.32% to a bank in exchange for being paid the Rate.
 
     The differences to be paid or received on the interest sensitive payment
and swap were included as an adjustment to direct cost of services. The Company
recorded a reduction to direct cost of services of $643 and $852 for the years
ended December 31, 1997 and 1996, respectively. Based on anticipated cash flows,
discounted at the U.S. prime lending rate of 8.5%, the fair value of these
instruments was estimated to be a $1,102 benefit as of December 31, 1997. The
Company's remaining risk associated with these transactions was risk of default
by the client or the bank, which the Company believed to be remote.
 
     In April 1998, the Company paid a fee of $536 to terminate the above
interest rate swap agreement.

    Foreign currency exchange forward contracts
 
   
     At September 30, 1998, the Company had one British pound to U.S. dollar
forward contract in the amount of $10,033. This contract will expire on October
30, 1998. As of December 31, 1997, the Company had two British pound to U.S.
dollar forward contracts totaling $10,177 and $6,684 which matured in February
1998 and January 1998, respectively. A third forward contract of Swiss franc to
U.S. dollar totaling $8,108 matured in January 1998.
    
 
   
     The estimated fair value of the Company's forward exchange contracts using
bank or market quotes and the month end foreign exchange rates was a net
liability of $7 as of September 30, 1998, and a net liability of $18 as of
December 31, 1997. The Company's remaining risk associated with this transaction
is the risk of default by the bank, which the Company believes to be remote.
    
 
  Contracts
 
     In the normal course of business, the Company provides services to its
clients which may require the Company to comply with certain performance
criteria. The Company believes that the ultimate liability, if any, incurred
under these contracts will not have a material adverse effect on the Company's
consolidated results of operations or financial position.
 
  Contingent put rights
 
   
     Under the terms of various stock agreements, a total of 1,423,376 and
1,463,376 shares of Class A Common Stock are subject to contingent put rights at
September 30, 1998 and December 31, 1997, respectively. For 600,000 and 323,376
of these shares, the holders may require the Company to repurchase the shares at
fair value in the event the Company's Class A Common Stock is not publicly
traded by the years 2010 and 2000, respectively. For 500,000 of these shares at
September 30, 1998 and 540,000 at December 31, 1997, the holders may require the
Company to repurchase the shares at the original cost plus 8% interest, accrued
from the date of purchase, in the event the holders' employment or directorship
terminates.
    
 
  Litigation
 
     There are various claims and pending actions against the Company arising in
the ordinary course of the conduct of its business. The Company believes that
these claims and actions will have no material adverse effect on the Company's
financial condition, results of operations or cash flow.
 
  License Agreement
 
     In 1988, the Company entered into a license agreement with the Perot
Systems Family Corporation and Ross Perot that allowed the Company to use the
name "Perot" and "Perot Systems" in its business on a royalty-free basis. Mr.
Perot and the Perot Systems Family Corporation may terminate this agreement at
any time and for any reason. Beginning one year following such a termination,
the Company would not be allowed to use the "Perot" name in its business. Mr.
Perot's or the Perot Systems Family Corporation's termination of the Company's
license agreement could materially and adversely affect the Company's business,
financial condition and results of operations.
 
  Year 2000
 
     The inability of computers, software and other equipment utilizing
microprocessors to recognize and properly process date fields containing a 2
digit year is commonly referred to as the Year 2000 Compliance issue. As the
year 2000 approaches, such systems could be unable to accurately process certain
date-based information. The Company believes it has identified all significant
applications that will require modification

                             (DOLLARS IN THOUSANDS)
 
to ensure Year 2000 Compliance and does not believe compliance with the Year
2000 requirements will have a material adverse effect on the Company's business
or results of operations. The Company is performing an assessment of its
obligations to make any of its clients' systems Year 2000 compliant, including
an estimate of the cost and revenues to be incurred in fulfilling such
obligations, and monitors this assessment on an ongoing basis.
 
   
     As of September 30, 1998, the Company estimated the total cost of
completing any required modifications, upgrades, or replacements of its internal
systems to be approximately $1,000, almost all of which the Company believes
will be incurred during 1998 and 1999. This estimate is being monitored and will
be revised as additional information becomes available. In addition, the Company
recorded a $13,485 charge in direct cost of services during the nine months
ended September 30, 1998 to address Year 2000 exposures for certain client
contracts.
    
 
14. RETIREMENT PLAN AND OTHER EMPLOYEE TRUSTS
 
   
     During 1989, the Company established the Perot Systems 401(k) Retirement
Plan, a qualified defined contribution retirement plan. The plan year is January
1 to December 31 and allows eligible employees to contribute between 1% and 15%
of their annual compensation, including overtime pay, bonuses and commissions.
The plan was amended effective January 1, 1996 to change the Company's
contribution from 2% of the participants' defined annual compensation, to a
formula matching employees' contributions at a two-thirds rate, up to a maximum
Company contribution of 4%. The Company's cash contribution for the nine months
ended September 30, 1998 and 1997 and the years ended December 31, 1997, 1996
and 1995 amounted to $5,967; $6,162; $7,388; $4,785 and $1,919, respectively.
The Company's contribution of common stock for the nine months ended September
30, 1998 and 1997 and the years ended December 31, 1997, 1996 and 1995 totaled
0; 123,795; 128,795; 6,325 and 99,486 shares, respectively, which were allocated
to participants' plan accounts using a formula based on compensation.
Compensation expense of $0, $607, $631, $14, and $224, respectively, was
recorded as a result of these share contributions.
    
 
   
     In 1992 the Company established a European trust, for the benefit of
non-U.S. based employees, to which 11,926 shares were contributed in 1995.
Compensation expense of $26 was recorded in 1995 as a result of this grant.
    
 
   
     In 1996, the Company contributed 162,143 shares to certain trusts
established for the benefit of employees transitioning to the Company pursuant
to certain contracts. Compensation expense of $405 was recorded in 1996 related
to these grants.

16. RELATED PARTY TRANSACTIONS
 
   
     During 1996, 1997 and 1998 certain officers financed the purchase of Class
A Common Stock with a bank. All of these loans bear interest at rates between
9.5% and 9.75% and are due at various dates through September 15, 2000. The
Company had agreed that it would, at the request of NationsBank, purchase such
loans from NationsBank for an amount equal to principal plus accrued and unpaid
interest if the Company has not had an initial public offering that results in
the shares of Class A Common Stock being publicly traded before the maturity of
the notes. As of September 30, 1998 and December 31, 1997, approximately $1,420
and $1,546, respectively, remain outstanding under these loans.
    
 
   
     In March 1996, the Company loaned $615 to an executive. The note bears
interest at a rate of 5.98% per annum and is payable at the fifteenth
anniversary of the date of the note or at an earlier date if the Company's
common stock is publicly traded. In April 1997, the Company loaned an additional
$2,397 to this executive. For these additional loans, up to $1,169 is
collateralized by the Company's Class A shares held by this executive and $1,000
is collateralized by a mortgage on the executive's residence. These additional
loans will bear interest at the greater of 7.25% or the applicable federal rate.
As of June 30, 1998 and December 31, 1997, the principal balance remaining on
these notes was $2,169. In July 1997, the Company repurchased 1,400,000 shares
of common stock from this executive, following his resignation, through a
reduction of $1,830 in outstanding notes receivable.

     In August 1996, an officer of the Company obtained funding in the amount of
$350 from a bank. The Company entered into a third party agreement with this
bank under which, if the Company's Class A shares are not publicly traded prior
to the maturity date of the loan, the Company will purchase the loan at the
bank's option. The maturity date of this loan is February 26, 2000.
    
 
     In 1996, the Company entered into an agreement with Perot Investments, Inc.
("PII") pursuant to which the Company licensed certain software from PII. The
Company sublicensed such software to The Witan Company, L.P. ("Witan"). Witan
paid a license fee of $1,000 directly to PII in connection with the license. The
Company had a separate contract with Witan to perform development work on the
licensed software. The contract was terminated in 1997. PII is an affiliate of a
stockholder of the Company.
 
     In January and February 1997, the Company loaned $450 to an executive at
the rate of 8%. The notes were collateralized by the executive's Class A common
shares. Prior to year end, the notes and the related shares were canceled.
 
   
     In August 1997, the Company also loaned $250 to an executive at the rate of
8%. This note is collateralized by the executive's Class A shares and is payable
in August 2000.
    
 
   
     A former officer of the Company has three outstanding loans totaling $349
with the Company. These loans are secured by the Company's Class A shares held
by the executive and are due by December 31, 1999.
    
 
   
     In November 1997, Ross Perot became chief executive officer of the Company
and has been serving the Company without cash or non-cash compensation. For the
nine months ended September 30, 1998, the Company has recorded a compensation
expense of $585 with an offset to additional paid-in capital.
    
 
17. EARNINGS PER SHARE
 
   
     In 1997, the Company adopted Statement of Financial Accounting Standards
No. 128 (SFAS 128), "Earnings Per Share," effective for fiscal years ending
after December 15, 1997. SFAS 128 replaces the presentation of primary earnings
per common share with basic earnings per common share, with the principal
difference being that common stock equivalents are not considered in computing
basic earnings per share. The following chart is a reconciliation of the
numerators and the denominators of the basic and diluted per-share computations.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company's Amended and Restated Certificate of Incorporation and Amended
and Restated Bylaws provide that officers and directors who are made a party to
or are threatened to be made a party to or is otherwise involved in any action,
suit, or proceeding, whether civil, criminal, administrative, or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was an officer or a
director of the Company or is or was serving at the request of the Company as a
director or an officer of another corporation or of a partnership, joint
venture, trust, or other enterprise, including service with respect to an
employee benefit plan (an "indemnitee"), whether the basis of such proceeding is
alleged action in an official capacity as a director or officer or in any other
capacity while serving as a director or officer, shall be indemnified and held
harmless by the Company to the fullest extent authorized by the Delaware General
Corporation Law ("DGCL"), as the same exists or may hereafter be amended (but,
in the case of any such amendment, only to the extent that such amendment
permits the Company to provide broader indemnification rights than permitted
prior thereto), against all expense, liability, and loss (including, without
limitation, attorneys' fees, judgments, fines, excise taxes or penalties, and
amounts paid or to be paid in settlement) incurred or suffered by such
indemnitee in connection therewith and such indemnification shall continue with
respect to an indemnitee who has ceased to be a director or officer and shall
inure to the benefit of the indemnitee's heirs, executors and administrators;
provided, however, that the Company shall indemnify any such indemnitee in
connection with a proceeding initiated by such indemnitee only if such
proceeding was authorized by the Board of Directors. The right to
indemnification includes the right to be paid by the Company for expenses
incurred in defending any such proceeding in advance of its final disposition.
Officers and directors are not entitled to indemnification if such persons did
not meet the applicable standard of conduct set forth in the DGCL for officers
and directors.
 
     DGCL Section 145 provides, among other things, 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 (other than
an action by or in the right of the Company) by reason of the fact that the
person is or was a director, officer, agent or employee of the Company or is or
was serving at the Company's request as a director, officer, agent, or employee
of another corporation, partnership, joint venture, trust or other enterprise,
against expenses, including attorneys' fees, judgments, fines and amounts paid
in settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding. The power to indemnify applies (a) if such
person is successful on the merits or otherwise in defense of any action, suit
or proceeding, or (b) if such person acted in good faith and in a manner he
reasonably believed to be in the best interest, or not opposed to the best
interest, of the Company, and with respect to any criminal action or proceeding,
had no reasonable cause to believe his conduct was unlawful. The power to
indemnify applies to actions brought by
 
                                      II-1
<PAGE>   104
 
or in the right of the Company as well, but only to the extent of defense
expenses (including attorneys' fees but excluding amounts paid in settlement)
actually and reasonably incurred and not to any satisfaction of a judgment or
settlement of the claim itself, and with the further limitation that in such
actions no indemnification shall be made in the event of any adjudication of
negligence or misconduct in the performance of his duties to the Company, unless
the court believes that in light of all the circumstances indemnification should
apply.
 
     The indemnification provisions contained in the Company's Amended and
Restated Certificate of Incorporation and Amended and Restated Bylaws are not
exclusive of any other rights to which a person may be entitled by law,
agreement, vote of stockholders or disinterested directors or otherwise. In
addition, the Company maintains insurance on behalf of its directors and
executive officers insuring them against any liability asserted against them in
their capacities as directors or officers or arising out of such status.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing 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
of 1933 may be permitted to directors, officers, and controlling persons of the
registrant pursuant to the provisions described in Item 14, or otherwise, the
registrant has been informed that in the opinion of the Securities and Exchange
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 by the registrant 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 hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of Prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a 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 this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, 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 the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

NationsBank, N.A.           PROMISSORY NOTE

                                                           Date   July 31, 1998

                                                           Amount $40,000,000.00

FOR VALUE RECEIVED, the undersigned ("Borrower") unconditionally (and jointly 
and severally, if more than one) promise(s) to pay to the order of NationsBank, 
N.A. ("Bank"), _______________________ (Banking Center) without setoff, at its 
offices at Charlotte, North Carolina, or at such other place as may be 
designated by Bank, the principal amount of Forty Million and 00/100 Dollars 
($40,000,000.00), or so much thereof as may be advanced from time to time in 
immediately available funds, together with interest computed daily on the 
outstanding principal balance hereunder, at an annual interest rate, and in 
accordance with the payment schedule, indicated below. [This Note contains some 
provisions preceded by boxes. Mark only those boxes beside provisions which 
will be applicable to this transaction. A box which is not marked means that 
the provision beside it is not applicable to this transaction.]

RATE

[ ] PRIME RATE. The rate shall be the Prime Rate, plus _________ percent, per 
    annum. The "Prime Rate" is the fluctuating rate of interest established by
    Bank from time to time, at its discretion, whether or not such rate shall be
    otherwise published. The Prime Rate is established by Bank as an index or
    base rate and may or may not at any time be the best or lowest rate charged
    by Bank on any loan.

[ ] FIXED RATE. The Rate shall be fixed at ____________ percent, per annum.

[ ] TREASURY SECURITIES RATE. The Rate shall be the Treasury Securities Rate, 
    plus ___________ percent, per annum. The "Treasury Securities Rate" is a
    fluctuating rate of interest applied by Bank from time to time, based on the
    most recent monthly average of daily yields on all outstanding United States
    Treasury Securities adjusted to a constant maturity of __________ years, as
    made available by the Federal Reserve Board, rounded upwards to the nearest
    one-eighth of one percentage point (0.125%).

[X] OTHER. The Rate shall be (i) Adjusted Eurodollar Rate plus one percent (1%) 
    or (ii) the Prime Rate as provided in the Addendum. INTEREST WILL BE PAYABLE
    IN ARREARS.

Notwithstanding any other provision contained in this Note, Bank does not 
intend to charge and Borrower shall not be required to pay any amount of 
interest or other fees or charges that is in excess of the maximum permitted by 
applicable law. Any payment in excess of such maximum shall be refunded to 
Borrower or credited against principal, at the option of Bank. SEE ADDENDUM FOR 
ADDITIONAL PROVISIONS.

ACCRUAL METHOD

Interest at the Rate set forth above, unless otherwise indicated, will be 
calculated on the basis of the 365/360 method, which computes a daily amount of 
interest for a hypothetical year of 360 days, then multiplies such amount by 
the actual number of days elapsed in an interest calculation period. If 
interest is not to be computed using this method, the method to be used shall 
be: ________________________________________________________________________.

RATE CHANGE DATE

Any Rate based on a fluctuating index or base rate will change, unless 
otherwise provided, each time and as of the date that the index or base rate 
changes. If the Rate is to change on any other date or at any other interval, 
describe: __________________________________________________________________
____________________________________________________________________________.
In the event any index is discontinued, Bank shall substitute an index 
determined by Bank to be comparable, in its sole discretion.

PAYMENT SCHEDULE

All payments received hereunder shall be applied first to the payment of any 
expense or charges payable hereunder or under any other documents executed in 
connection with this Note ("Loan Documents"), then to interest due and payable, 
with the balance being applied to principal, or in such other order as Bank 
shall determine at its option.

[ ] PRINCIPAL    Principal shall be paid in __________________ (____) equal: 
    PLUS         [ ] monthly, [ ] quarterly or [ ] _______________ installments
    INTEREST     of $________________ each, commencing on __________________,

                 on the same day of each successive month/quarter/or other
                 period (as applicable) thereafter, with a final payment of all
                 unpaid principal and interest thereon on ____________________,
                 19____.

[ ] PRINCIPAL    Principal shall be paid in __________________ (____) equal: 
    PLUS         [ ] monthly, [ ] quarterly or [ ] _______________ installments
    INTEREST     of $________________ each, commencing on __________________,
                 19____, and continuing on the same day of each successive
                 month/quarter/or other period (as applicable) thereafter, with
                 a final payment of all unpaid principal and interest thereon on
                 ____________________, 19____; provided that, if accrued
                 interest on any payment date exceeds the installment amount set
                 forth above, Borrower will pay an additional amount equal to
                 such excess interest.

    PRINCIPAL    31, 1999. Interest thereon shall be paid: [ ] at maturity, [X]

                 successive month/quarter or other period (as applicable)
                 thereafter, with a final payment of all unpaid interest at the
                 stated maturity of this Note. AS PROVIDED IN THE ADDENDUM 

                 [ ] DEMAND. NOTWITHSTANDING ANY PROVISIONS CONTAINED HEREIN 
                             WHICH MAY BE INCONSISTENT WITH A DEMAND NOTE,
                             INCLUDING BUT NOT LIMITED TO ANY REFERENCES TO
                             INSTALLMENTS, A MATURITY DATE, ACCELERATION OR
                             EVENTS OF DEFAULT, BORROWER ACKNOWLEDGES THAT BANK

REVOLVING FEATURE

[X] Borrower may borrow, repay and reborrow hereunder at any time, up to a 
maximum aggregate amount outstanding at any one time equal to the principal 
amount of this Note; provided, however, that Borrower is not in default under 
any provision of this Note, any Loan Document, or any other obligation of 
Borrower to Bank, and provided that the borrowings hereunder do not exceed any 
borrowing base or other limitations on borrowings by Borrower. Bank shall have 
no liability for its refusal to advance funds based upon its determination that 
any conditions of such further advances have not been met. Bank records of the 
amounts borrowed from time to time shall be conclusive proof thereof.

     [ ] Uncommitted Facility. Borrower acknowledges and agrees that 
         notwithstanding any provisions of this Note or the Loan Documents, Bank
         has no obligation to make any advance, and that all advances are at the
         sole discretion of Bank.

AUTOMATIC PAYMENT

[ ] Borrower has elected to authorize Bank to effect payment of sums due under 
this Note by means of debiting Borrowers account number ______________________. 
This authorization shall not affect the obligation of Borrower to pay such sums 
when due, without notice, if there are insufficient funds in such account to 
make such payment in full on the due date thereof, or if Bank fails to debit 
the account.

BORROWER REPRESENTS TO BANK THAT THE PROCEEDS OF THIS LOAN ARE TO BE USED 
PRIMARILY FOR BUSINESS, COMMERCIAL OR AGRICULTURAL PURPOSES. BORROWER 
ACKNOWLEDGES HAVING READ AND UNDERSTOOD, AND AGREES TO BE BOUND BY, ALL TERMS 
AND CONDITIONS OF THIS NOTE, INCLUDING THE ADDITIONAL TERMS AND CONDITIONS SET

ADDITIONAL TERMS AND CONDITIONS    SEE ADDENDUM FOR ADDITIONAL PROVISIONS

WAIVERS, CONSENTS AND COVENANTS. Borrower, any indorser, or guarantor hereof or
any other party hereto (collectively "Obligors") and each of them jointly and
severally, do waive presentment, demand, notice of demand, notice of intent to
accelerate, and notice of acceleration of maturity, protest, notice of protest,
notice of nonpayment, notice of dishonor, and any other notice required to be
given under the law to any of Obligors, in connection with the delivery,
acceptance, performance, default or enforcement of this Note, any indorsement or
guaranty of this Note or of any Loan Documents; (b) consent to any and all
delays, extensions, renewals or other modifications of this Note or the Loan
documents, or waivers of any term hereof or of the Loan Documents, or releases
or discharge by Bank of any of Obligors or release, substitution, or exchange of
any security for the payment hereof, or the failure to act on the part of Bank
or any indulgence shown by Bank, from time to time and in one or more instances
(without notice to or further assent from any of Obligors) and agree that no
such action, failure to act or failure to exercise any right or remedy on the
part of Bank shall in any way affect or impair the obligations of any Obligors
or be construed as a waiver by Bank of, or otherwise affect, any of Bank's
rights under this Note, under any indorsement or guaranty of this Note or under
any of the loan Documents; and (c) agree to pay, on demand, all costs and
expenses of collection of this Note or of any indorsement or guaranty hereof
and/or the enforcement of Bank's rights with respect to, or the administration,
supervision, preservation, protection of, or realization upon, any property
securing payment hereof, including, without limitation, reasonable attorney's
fees, including fees related to any trial, arbitration, bankruptcy, appeal or
other proceeding, in the amount of 15% of the outstanding balance of this Note.

INDEMNIFICATION. Obligors agree to promptly pay, indemnify and hold Bank
harmless from all state and federal taxes of any kind and other liabilities with
respect to or resulting from advances made pursuant to this Note. If this Note
has a revolving feature and is secured by a mortgage, Obligors expressly consent
to the deduction of any applicable taxes from each taxable advance extended by
Bank.

PREPAYMENTS. Prepayments may be made in whole or in part at any time on any loan
for which the Rate is based on the Prime Rate. All prepayments of principal
shall be applied in the inverse order of maturity, or in such other order as
Bank shall determine in its sole discretion. Except as expressly permitted by
law, no prepayment of any other loan shall be permitted without the prior
written consent of Bank. Notwithstanding such prohibition, if there is a
prepayment of any such loan, whether by consent of Bank, or because of
acceleration or otherwise, Borrower shall, within 15 days of any request by
Bank, pay to Bank any loss or expense which Bank may incur or sustain as a
result of such prepayment. For the purposes of calculating the amounts owed
only, it shall be assumed that Bank actually funded or committed to fund the
loan through the purchase of an underlying deposit in an amount and for a term
comparable to the loan, and such determination by Bank shall be conclusive,
absent a manifest error in computation.

EVENTS OF DEFAULT. The following are events of default hereunder: (a) the
failure to pay or perform any obligation, liability or indebtedness of any
Obligor to Bank, or to any affiliate of Bank, whether under this Note or any
other Agreement, note or instrument now or hereafter existing, as and when due
(whether upon demand, at maturity or by acceleration); (b) the failure to pay
or perform any other obligation, liability or indebtedness of any of Obligors
whether to Bank or some other party, the security for which institutes an
encumbrance on the security for this Note; (c) death of any Obligor (if an
individual), or a proceeding being filed or commenced against any Obligor for
dissolution or liquidation, or any Obligor voluntarily or involuntarily
terminating or dissolving or being terminated or dissolved; (d) insolvency of,
business failure of, the appointment of a custodian, trustee, liquidator or
receiver for or for any of the property of, or an assignment for the benefit of
creditors by, or the filing of a petition under bankruptcy, insolvency or
debtor's relief law or for any adjustment of indebtedness, composition or
extension by or against any Obligor; (e) any lien or additional security
interest being placed upon any of the property which is security for this Note;
(f) acquisition at any time or from time to time of title to the whole of or
any part of the property which is security for this Note by any person,
partnership, corporation or other entity; (g) Bank determining that any
representation or warranty made by any Obligor in any Loan Documents or
otherwise to Bank is, or was, untrue or materially misleading; (h) failure of
any Obligor to timely deliver such financial statements, including tax returns,
and other statements of condition or other information as Bank shall request
from time to time; (i) any default under any Loan Documents; (j) entry of a
judgment against any Obligor which Bank deems to be of a material nature, in
Bank's sole discretion; (k) the seizure or forfeiture of, or the issuance of
any writ of possession, garnishment or attachment, or any turnover order for
any property of any obligor; (l) Bank reasonably deeming itself insecure for
any reason; (m) the determination by Bank that a material adverse change has
occurred in the financial condition of any obligor; or, (n) the failure to
comply with any law or regulation regulating the operation of Borrower's
business.

REMEDIES UPON DEFAULT. Whenever there is a default under this Note (a) the
entire balance outstanding and all other obligations of Obligor to Bank
(however acquired or evidenced) shall, at the option of Bank, become
immediately due and payable, and/or (b) to the extent permitted by law, the
Rate of interest on the unpaid principal shall, at the option of the Bank, be
increased at Bank's discretion up to the greater of (i) three percent (3%) over
the contract rate (as shown on the face of this Note) or (ii) three Percent
(3%) over the Prime Rate of Bank ("Default Rate"); and/or (c) to the extent
permitted by law, a delinquency charge may be imposed in an amount not to
exceed four percent (4%) of the paid portion of any payment in default for more
than fifteen days. Unless the terms of this Note call for repayment of the
entire balance of this Note (both principal and interest) a single payment (and
not for installments of interest or principal and interest), the four percent
(4%) delinquency charge may be imposed not only with respect to regular
installments of principal, interest, or interest and principal, but also with
respect to any other payment in default (other than a previous delinquency
charge) for more than fifteen days, including without limitation, a single
payment of principal due at maturity of this Note. In the event that any
installment, or portion thereof, is not paid in a timely fashion, subsequent
payments will be applied first to the past due balance (which shall not include
any previous delinquency charges), specifically to the oldest maturing
installment, and a separate delinquency charge will be imposed for each payment
that becomes due until the default is cured. The provisions herein for a
Default Rate or a delinquency charge shall not be deemed to extend the time for
any payment hereunder or to constitute a "grace period" giving the Obligors a
right to cure any default. At Bank's option, any accrued and paid interest,
fees or charges may, for purposes of computing and accruing interest on a daily
basis after the due date of the Note or any installment thereof, be deemed to
be a part of the principal balance, and interest shall accrue on a daily
compounded basis after such date at the rate provided in this Note until the
entire outstanding balance of principal and interest is paid in full. Bank is
hereby authorized at any time to set off and charge against any deposit
accounts of any Obligor, as well as any other property of such party at or
under the control of Bank, without notice or demand, any and all obligations
due hereunder.

NON-WAIVER. The failure at any time of Bank to exercise any of its options or
any other rights hereunder shall not constitute a waiver thereof, nor shall it
be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of
Bank's rights under this Note. No waiver of any of its rights hereunder, and
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; and each
such waiver, if any, shall apply only with respect to the specific instance
involved, and shall in no way impair the rights of Bank or the obligations of
Obligor to Bank in any other respect at any other time.

APPLICABLE LAW. This Note is delivered in and shall be construed under the
internal laws and judicial decisions of the State of North Carolina, and the
laws of the United States as the same may be applicable.

PARTIAL INVALIDITY. The unenforceability or invalidity of any provision of this
Note shall not affect the enforceability or the validity of any other provision
herein and the validity or unenforceability of any provision of this Note or of
the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as may apply to other persons or
circumstances.

JURISDICTION AND VENUE. In any litigation in connection with or to enforce this
Note or any indorsement or guaranty of this Note or any Loan Documents,
Obligors, and each of them, irrevocably consent to and confer personal
jurisdiction on the courts of the State of North Carolina or the United States
courts located within the State of North Carolina, and expressly waive any
objections as to venue in any such courts, and agree that service of process may
be made on Obligors by mailing a copy of the summons and complaint by registered
or certified mail, return receipt requested, to their respective addresses.
Nothing contained herein shall, however, prevent Bank from bringing any action
or exercising any rights within any other state or jurisdiction or from
obtaining personal jurisdiction by any other means available by applicable law.

ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES HERETO
INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS NOTE OR AN
RELATED NOTES OR INSTRUMENTS, INCLUDING ANY CLAIM BASED ON OR ARISING FROM AN
ALLEGED TORT, SHALL BE DETERMINED BY BINDING ARBITRATION IN ACCORDANCE WITH THE
FEDERAL ARBITRATION ACT (OR IF NOT APPLICABLE, THE APPLICABLE STATE LAW), THE
RULES OF PRACTICE AND PROCEDURE FOR THE ARBITRATION OF COMMERCIAL DISPUTES OR
JUDICIAL ARBITRATION AND MEDIATION SERVICES, INC. (J.A.M.S.) AND THE "SPECIAL
RULES" SET FORTH BELOW. IN THE EVENT OF ANY CONSISTENCY, THE SPECIAL RULES SHALL
CONTROL. JUDGMENT UPON ANY ARBITRATION AWARD MAY BE ENTERED IN ANY COURT HAVING
JURISDICTION, ANY PARTY TO THE NOTE MAY BRING AN ACTION, INCLUDING A SUMMARY OR
EXPEDITED PROCEEDING, TO COMPEL ARBITRATION OF ANY CONTROVERSY OR CLAIM TO WHICH
THIS NOTE APPLIES IN ANY COURT HAVING JURISDICTION OVER SUCH ACTION.

     (A)  SPECIAL RULES. THE ARBITRATION SHALL BE CONDUCTED IN THE CITY OF

SHOWING OF CAUSE, BE PERMITTED TO EXTEND THE COMMENCEMENT OF SUCH HEARING FOR AN
ADDITIONAL 60 DAYS.

     (B)  RESERVATION OF RIGHTS. NOTHING IN THIS NOTE SHALL BE DEEMED TO (I) 
LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF LIMITATION OR

EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT LIMITED TO) SETOFF, OR (B) TO

BANK MAY EXERCISE SUCH SELF HELP RIGHTS, FORECLOSURE UPON SUCH PROPERTY, OR
OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES BEFORE, DURING OR AFTER THE
PENDENCY OF ANY ARBITRATION PROCEEDING BROUGHT PURSUANT TO THIS NOTE. NEITHER
THE EXERCISE OR SELF HELP REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN
ACTION FOR FORECLOSURE OR PROVISIONAL OR ANCILLARY REMEDIES SHALL CONSTITUTE A
WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING THE CLAIMANT IN SUCH ACTION, TO
ARBITRATE THE MERITS OF THE CONTROVERSY OR CLAIM OCCASIONING RESORT TO SUCH
REMEDIES.

BINDING EFFECT. This note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successor, assigns, heirs and
personal representatives, provided, however, that no obligations of the Borrower
or the Obligor hereunder can be assigned without prior written consent of Bank.

NOTICE OF FINAL AGREEMENT. THIS WRITTEN PROMISSORY NOTE AND ANY OTHER DOCUMENTS

                                  ADDENDUM TO
             $40,000,000 DEMAND PROMISSORY NOTE DATED JULY 31,1998
                          OF PEROT SYSTEMS CORPORATION
                                  IN FAVOR OF
                               NATIONSBANK, N.A.

     The above-referenced Note is amended and modified to include the following
terms:

     LOAN

     Commitment. During the Commitment Period, subject to the terms and
conditions hereof, the Bank agree to make revolving loans to the Borrower upon
request up to an aggregate principal amount of FORTY MILLION DOLLARS
($40,000,000) at any time outstanding. The loans hereunder may consist of Base
Rate Loans or Eurodollar Loans, or a combination thereof; provided that no more
than 8 Eurodollar Loans may be outstanding at any time. The obligation of the
Bank to make loans hereunder and to extend, or convert loans into, Eurodollar
Loans is subject to the condition that the Representations and Warranties set
forth herein are true and correct in all material respects.

     Notices. Requests by the Borrower for loans hereunder, and for extensions
or conversions of loans hereunder, shall be made by written notice (or telephone
notice promptly confirmed in writing) by 12:00 Noon Charlotte, North Carolina
time on (i) the Business Day prior to the requested borrowing, extension or
conversion in the case of Base Rate Loans and (ii) the third Business Day prior
to the requested borrowing, extension or conversion in the case of Eurodollar
Loans. Each request shall be in a minimum principal amount of $1,000,000 in the
case of Eurodollar Loans and $ 100,000 in the case of Base Rate Loans and, in
each case, integral multiples of $100,000 in excess thereof, and shall specify
the date of the requested borrowing, extension or conversion, the aggregate
amount to be borrowed, extended or converted and if an extension of conversion,
the loan which is being extended or converted, and whether the borrowing,
extension or conversion shall consist of Eurodollar Loans, Base Rate Loans or
combination thereof. If the Borrower shall fail to specify (A) the type of Loan
requested for a borrowing, the request shall be deemed a request for a Base Rate
Loan, (B) the duration of the applicable Interest Period in the case of
Eurodollar Loans, the request shall be deemed to be a request for an Interest
Period of one month. Each request for a borrowing, extension or conversion
hereunder shall be deemed a reaffirmation that the Representations and
Warranties set forth herein are true and correct in all material respects as of
such date. Unless extended in accordance with the provisions hereof, Eurodollar
Loans shall be converted to Base Rate Loans at the end of the applicable
Interest Period.

     RATE

     The Rate shall be either (i) the Adjusted Eurodollar Rate plus one percent
or (ii) the Prime Rate, as the Borrower may elect. Interest will be payable in
arrears on each Interest Payment Date.

     Capital Adequacy. If the Bank has reasonably determined, after the date
hereof, that the adoption or the becoming effective of, or any change in, or any
change by any Governmental Authority, central bank or comparable agency charged
with the interpretation or administration thereof in the interpretation or
administration of, any applicable law, rule or regulation regarding capital
adequacy, in each case after the date hereof, or compliance by the Bank with any
request or directive regarding capital adequacy (whether or not having the force
of law) of any such authority, central bank or comparable agency, after the date
hereof, has or would have the effect of reducing the rate of return on the
Bank's capital or assets as a consequence of its commitments or obligations
hereunder to a level below that which the Bank could have achieved but for such
adoption, effectiveness, change or compliance (taking into consideration the
Bank's policies with respect to capital adequacy), then, upon notice from the
Bank to the Borrower, the Borrower shall be obligated to pay to the Bank such
additional amount or amounts as will compensate the Bank for such reduction.
Each determination by the Bank of amounts owing under this paragraph shall,
absent manifest error, be conclusive and binding on the parties hereto. The Bank
shall not be entitled to any payments or compensation under this paragraph for
any period of time more than 90 days prior to the date of any request by the
Bank for compensation under this paragraph.

                                                                Addendum to
                                                        $40,000,000 Demand Note
                                                       Perot Systems Corporation
                                                          dated July 31, 1998

     Inability To Determine Interest Rate. If prior to the first day of any
Interest Period, the Bank shall have reasonably determined (which determination
shall be conclusive and binding upon the Borrower absent manifest error) that,
by reason of circumstances affecting the relevant market, adequate and
reasonable means do not exist for ascertaining the Eurodollar Rate for such
Interest Period, the Bank shall give telecopy or telephonic notice thereof to
the Borrower. If such notice is given (x) any Eurodollar Loans requested to be
made on the first day of such Interest Period shall be made as Base Rate Loans,
(y) any Loans that were to have been converted on the first day of such Interest
Period to or continued as Eurodollar Loans shall be converted to or continued as
Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on
the last day of such Interest Period, to Base Rate Loans. Until such notice has
been withdrawn by the Bank, no further Eurodollar Loans shall be made or
continued as such, nor shall the Borrower have the right to convert Base Rate
Loans to Eurodollar Loans.

     Illegality. Notwithstanding any other provision herein, if the adoption of
or any change in any Requirement of Law or in the interpretation or application
thereof occurring after the date hereof shall make it unlawful for the Bank to
make or maintain Eurodollar Loans as contemplated hereunder, (a) the Bank shall
promptly give written notice of such circumstances to the Borrower (which notice
shall be withdrawn whenever such circumstances no longer exist), (b) the
commitment, if any, of the Bank hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert a Base Rate Loan to Eurodollar Loans shall
forthwith be canceled and, until such time as it shall no longer be unlawful for
the Bank to make or maintain Eurodollar Loans, the Bank shall then have a
commitment only to make a Base Rate Loan when a Eurodollar Loan is requested and
(c) the Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to Base Rate Loans on the respective last days or the then
current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to the Bank such amounts, if any, as may be
required pursuant to the paragraph entitled "Indemnity".

     Requirements of Law. If, after the date hereof, the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
applicable to the Bank, or compliance by the Bank with any request or directive
(whether or not having the force of law) from any central bank or other
Governmental Authority, in each case made after the date hereof:

         (a) shall subject the Bank to any tax of any kind whatsoever with
     respect to any Eurodollar Loans made by it or its obligation to make
     Eurodollar Loans, or change the basis of taxation of payments to the Bank
     in respect thereof (except for Non-Excluded Taxes covered by the paragraph
     entitled "Taxes" (including Non-Excluded Taxes imposed solely by reason of
     any failure of the Bank to comply with its obligations under the paragraph
     entitled "Taxes") and changes in taxes measured by or imposed upon the
     overall net income, or franchise tax (imposed in lieu of such net income
     tax), of the Bank or its applicable lending office, branch, or any
     affiliate thereof);

         (b) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of the Bank which is not otherwise included in the determination of
     the Eurodollar Rate hereunder; or

         (c) shall impose on the Bank any other condition (excluding any tax of
     any kind whatsoever);

and the result of any of the foregoing is to increase the cost to the Bank, by
an amount which the Bank deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, upon notice to the
Borrower from the Bank, the

                                                        $40,000,000 Demand Note

                                                          dated July 31, 1998

Borrower shall be obligated to promptly pay the Bank, upon its demand, any
additional amounts necessary to compensate the Bank for such increased cost or
reduced amount receivable, provided that, in any such case, the Borrower may
elect to convert the Eurodollar Loans hereunder to Base Rate Loans by giving the
Bank at least one Business Day's notice of such election, in which case the
Borrower shall promptly pay to the Bank, upon demand, without duplication, such
amounts, if any, as may be required pursuant to the paragraph entitled
"Indemnity". If the Bank becomes entitled to claim any additional amounts
pursuant to this subsection, it shall provide prompt notice thereof to the
Borrower certifying (x) that one of the events described in paragraph (a) has
occurred and describing in reasonable detail the nature of such event, (y) as to
the increased cost or reduced amount resulting from such event and (z) as to
the additional amount demanded by the Bank and a reasonably detailed explanation
of the calculation thereof. Such a certificate as to any additional amounts
payable pursuant to this subsection submitted by the Bank hereunder shall be
conclusive and binding on the parties hereto in the absence of manifest error.
This covenant shall survive the termination of this Note and the payment of the
Loans and all other amounts payable hereunder. The Bank shall not be entitled to
any payments or compensation under this paragraph for any period of time more
than 90 days prior to the date of any request by the Bank for compensation under
this paragraph.

     Taxes. Except as provided below in this subsection, all payments made by
the Borrower under this Note shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future income,
stamp or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any court, or governmental body, agency or other official, excluding taxes
measured by or imposed upon the overall net income of the Bank or its applicable
lending office, or any branch or affiliate thereof, and all franchise taxes,
branch taxes, taxes on doing business or taxes on the overall capital or net
worth of the Bank or its applicable lending office, or any branch or affiliate
thereof, in each case imposed in lieu of net income taxes, imposed: (i) by the
jurisdiction under the laws of which the Bank, applicable lending office, branch
or affiliate is organized or is located, or in which its principal executive
office is located, or any nation within which such jurisdiction is located or
any political subdivision thereof; or (ii) by reason of any connection between
the jurisdiction imposing such tax and the Bank, applicable lending office,
branch or affiliate other than a connection arising solely from the Bank having
executed, delivered or performed its obligations, or received payment under or
enforced, this Note. If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required to
be withheld from any amounts payable to the Bank hereunder or under any Notes,
(A) the amounts so payable to the Bank shall be increased to the extent
necessary to yield to the Bank (after payment of all Non-Excluded Taxes)
interest or any such other amounts payable hereunder at the rates or in the
amounts specified in this Note, and (B) as promptly as possible thereafter the
Borrower shall send to the Bank for its own account a certified copy of an
original official receipt received by the Borrower showing payment thereof. If
the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate
taxing authority or fails to remit to the Bank the required receipts or other
required documentary evidence, the Borrower shall indemnify the Bank for any
incremental taxes, interest or penalties that may become payable by the Bank as
a result of any such failure. The agreements in this subsection shall survive
the termination of this Note and the payment of the Loans and all other amounts
payable hereunder. The Bank shall not be entitled to payment or compensation
under this paragraph unless demand is made hereunder within 90 days of the Bank
having actual knowledge of facts or circumstances entitling the Bank to
compensation under this paragraph.

     Indemnity. The Borrower promises to indemnify the Bank and to hold the Bank
harmless from any loss or expense which the Bank may sustain or incur (other
than through the Bank's gross negligence or willful misconduct) as a consequence
of (a) default by the Borrower in making a borrowing of, conversion into or
continuation of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Note, (b) default
by the Borrower in making any prepayment of a Eurodollar Loan with respect to
which the Borrower has given a notice in accordance with the provisions of this
Note or (c) the making of a prepayment of Eurodollar Loans on a day which is not
the last day of an Interest Period with respect thereto. With

     No Change. Since December 31, 1997 there has been no development or event
which has had a material adverse effect on the condition (financial or
otherwise), operations, business or prospects of the Borrower and its
subsidiaries taken as a whole.

     Corporate Organization. The Borrower is a corporation duly organized,
validly existing and in good standing under the laws of the State of its
incorporation, is qualified to do business in each jurisdiction where failure to
so qualify would have a material adverse effect on the Borrower and its
subsidiaries taken as a whole and is in compliance with all Requirements of Law
except to the extent that failure to be in compliance would not have a material
adverse effect on the Borrower and its subsidiaries taken as a whole.

     Enforceable Obligation. The Borrower has the power and authority and legal
right to enter into, deliver and perform under this Note and has taken all
necessary corporate action to authorize the execution, delivery and performance
by it of this Note. This Note constitutes a legal, valid and binding obligation
of the Borrower enforceable against it in accordance with its terms except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally or by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

     No Default. No Event of Default or event or condition which with notice or
lapse of time, or both, would constitute an Event of Default, presently exists.

     Federal Regulations. No part of the proceeds of any Loan hereunder will be
used, directly or indirectly, for any purpose in violation of Regulation U of

     Year 2000 Compliance. The Borrower has (i) initiated a review and
assessment of all areas within its and each of its subsidiaries' business and
operations (including those affected by suppliers, vendors and customers) that
could be adversely affected by the "Year 2000 Problem" (that is, the risk that
computer applications used by the Company or any of its subsidiaries (or
suppliers, vendors and customers) may be unable to recognize and perform
property date-sensitive functions involving certain dates prior to and any date
after December 31, 1999), (ii) developed a plan and timeline for addressing the
Year 2000 Problem on a timely basis, and (iii) to date, implemented that plan in
accordance with that timetable. Based on the foregoing, the Borrower believes
that all computer applications (including, those of its suppliers, vendors and
customers) that are material to its or any of its Subsidiaries' business and
operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
(that is, be a "Year 2000 compliant"), except to the extent that a failure to do
so could not reasonably be expected to have a material adverse effect in the
condition (financial or otherwise), operations, business or prospects of the
Borrower and its subsidiaries taken as a whole.
