RELIANCE ON MAJOR CLIENTS

         In January 1996, the Company formed a strategic alliance with Swiss
Bank Corporation ("Swiss Bank"). This alliance involves (i) a long-term contract
for the Company to deliver IT services to Swiss Bank's SBC Warburg Division
("SBC Warburg"), (ii) separate agreements to provide services to other Swiss
Bank operating units and to permit the Company to use certain Swiss Bank assets
and (iii) the grant to Swiss Bank of options to acquire stock of the Company.

         In April 1997, the Company concluded the renegotiation of the terms of
its strategic alliance with Swiss Bank. The terms of the new alliance were
effective from January 1, 1997 through December 31, 2006. The renegotiation
included (i) the restructuring of the IT services contract for SBC Warburg, (ii)
the termination of all options to acquire stock of the Company that were granted
in connection with the original transactions and (iii) the sale to Swiss Bank of
stock of the Company and options to purchase stock of the Company. The
agreements that contain the terms of the Swiss Bank alliance, as renegotiated,
are collectively called the "Swiss Bank Agreements". Pursuant to the terms of
the Swiss Bank Agreements, the Company also holds a 40% stake in Swiss Bank's IT
subsidiary, Systor AG ("Systor"). A portion of the Company's interest in Systor
will be returned to Swiss Bank if the SBC Warburg EPI Agreement is terminated.
The portion that would be returned to Swiss Bank upon such a termination
declines ratably over a 10-year period, which began on January 1, 1997.

         During the year ended December 31, 1997, approximately 27% of the
Company's revenues were earned in connection with services performed on behalf
of Swiss Bank and its affiliates. If certain competitors of Swiss Bank acquire
more than 25% of the shares of Class A Common Stock of the Company ("Class A
Common Stock," and such shares, "Class A Shares") or another party (other than
an affiliate of Ross Perot) acquires more than 50% of the Class A Shares and, if
in either case, that acquisition is reasonably likely to have a significant
adverse impact on the performance of or the charges for the services



                                      3

rendered by the Company, Swiss Bank has the right to terminate the Swiss Bank
Agreements. The loss of Swiss Bank as a client would have a material adverse
effect on the Company's business, financial condition and results of operations.

         During the year ended December 31, 1997, approximately 10% of the
Company's revenues were earned in connection with services performed on behalf
of East Midlands Electricity (EME). The loss of this client could have a
material adverse effect on the Company's business, financial condition and
results of operations. No other client accounted for more than 10% of the
Company's revenue.

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 has a small share of the
highly-fragmented IT services market.

         With respect to large contracts, the Company's principal competitors
include International Business Machines Corporation, Andersen Consulting
LLP, Computer Sciences Corporation and Electronic Data Systems Corporation. Each
of these companies, as well as some other competitors, has greater financial
resources and a larger customer base than the Company and may have larger
technical, sales and marketing resources than the Company. The Company expects
to see additional competition as it addresses new markets and as the computing
and communications markets converge. The Company competes on the basis of a
number of factors both within and outside of its control, including price,
technological innovation, ability to invest in or acquire assets of potential
customers and strategic relationships with customers and suppliers. There can be
no assurance that the Company will be able to compete successfully against its
current or future competitors with respect to these or other factors in the
future. In addition, there can be no assurance that competition will not have a
material adverse effect on the Company's results of operations.

INFORMATION REGARDING GEOGRAPHIC REGIONS

         For information regarding geographic regions in which the Company
operates, see Note 12 to the Consolidated Financial Statements, "Certain
Geographic Data and Segment Information."

TRADEMARKS, PATENTS AND COPYRIGHTS

         The Company owns or has obtained licenses for a number of copyrights
and trademarks relating to its products and services. 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.

EMPLOYEES

         As of December 31, 1997, the Company employed approximately 5,500
persons located in the United States and several other countries. None of the
Company's United States employees are currently employed under an agreement with
a collective bargaining unit. The Company's employees in France and Germany are
generally members of work councils and have worker representatives. These
representatives must be consulted on any major change in operations that affects
such employees. The Company believes that its relations with employees are good.

ITEM 2.  PROPERTIES

         As of December 31, 1997, the Company had approximately 40 locations in
the United States and five countries outside the United States. The Company owns
no real estate. The Company leases approximately 1.1 million square feet of
office and warehouse facilities. Current leases have expiration dates that range
from 1998 to 2012. 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 customer locations throughout the world. Such space is
generally occupied pursuant to the terms of the respective customer contract.

         The Company's management believes that its facilities are suitable and
adequate for its business. However, the Company has plans for expansion and is
currently negotiating for expanded facilities for several of its locations. The
Company does not anticipate any difficulty in obtaining sufficient space to
accommodate the planned expansion.


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 financial statements.

ITEM 3.  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.

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

         No matters were submitted to a vote of the Company's security holders
during the fourth quarter of the fiscal year ended December 31, 1997.

                                   PART II

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

         There is no established public trading market for the registrant's
securities. As of March 16, 1998, there were 1,196 holders of record of the
Class A common stock and one (1) holder of the Class B common stock.

         The Company has never paid cash dividends on its common stock. The
Company currently intends to retain earnings for use in its business and does
not anticipate paying any cash dividends in the foreseeable future.

ITEM 7.  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 Notes to the Consolidated Financial
Statements, which are included herein.

RESULTS OF OPERATIONS

Comparison of the year ended December 31, 1997 to the year ended December 31,
1996
                                                                             
         Contract revenue increased in 1997 by 30% to $781.6 million from $599.4
million in 1996, due to $43.6 million in revenue growth from the Company's Swiss
Bank contract, $60.2 million in revenue from businesses acquired in the second
half of 1996 and the first half of 1997, and a $78.4 million increase in revenue
from other new and existing business.

         Domestic contract revenue grew by 42% in 1997 to $519.1 million from
$365.2 million in 1996, and increased as a percentage of total contract revenue
to 66% from 61% over the same periods.

         Non-domestic contract revenue, consisting of European and Asian
operations, grew by 12% in 1997 to $262.5 million from $234.2 million in 1996,
and decreased as a percentage of total contract revenue to 34%, from 39% over
the same periods.

         Direct cost of services increased in 1997 by 38% to $636.3 million from
$461.2 million in 1996, due in part to general business growth. Growth in direct
costs of services exceeded revenue growth due to the combination of start-up
costs from sales to new clients and the integration of acquired businesses. In
addition, the Company incurred several non-recurring charges in 1997, including
special contract loss provisions of $10.2 million, related to known termination
and contract completion losses on certain 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.

         Selling, general and administrative expenses ("SG&A") increased in 1997
by 35% to $125.7 million from $93.0 million in 1996, due primarily to expansion
of the sales force, staff growth in management and administrative support areas,
severance for key executives and increased goodwill amortization associated with
businesses acquired. SG&A increased as a percentage of total revenue in 1997 to
16.1% from 15.5 % in 1996.

          Equity in earnings of unconsolidated affiliates, net, increased in
1997 to $4.1 million from a loss of $0.3 million in 1996 due primarily to
significantly improved results from the Company's investment in Systor AG, a
subsidiary of Swiss Bank. Other income, net, increased in 1997 to $1.0 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.

         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%. Net income margin in 1997 decreased to 1.4% from 3.4% over
the same period in 1996.

          Prior to the non-recurring 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

         Contract revenue increased in 1996 by 75% to $599.4 million from $342.3
million in 1995, due to $168.9 million in revenue from the Company's Swiss Bank
contract, $10.7 million in revenue from businesses acquired in the second half
of 1996, and a $77.5 million increase in revenue from other new and existing
business.

         Domestic contract revenue grew by 53% in 1996 to $365.2 million from
$238.8 million in 1995, but declined as a percentage of total contract revenue
to 61% from 70% over the same periods. Swiss Bank accounted for $88.9 million of
the domestic revenue in 1996.

         Non-domestic contract revenue, consisting of European and Asian
operations, grew by 126% in 1996 to $234.2 million from $103.5 million in 1995,
and increased as a percentage of total contract revenue to 39% from 30% over the
same periods. The key factor was the Swiss Bank contract revenue of which $72.7
million was earned in Europe and $7.3 million in Asia.

         Direct cost of services increased in 1996 by 72% to $461.2 million from
$268.6 million in 1995, due primarily to general business growth.

<PAGE>   12




         SG&A increased in 1996 by 76% to $93.0 million from $52.9 million in
1995, due primarily to the addition of key executives, expansion of the sales
force, staff growth in management and administrative support areas. SG&A
remained constant as a percentage of total revenue at 15.5% during 1995 and
1996.

         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.


         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. Net income margin increased in 1996 to 3.4% from 3.2% in 1995.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's primary source of liquidity over the past three years has
been cash flow from operating activities. For the year ended December 31, 1997,
operating cash flow was $71.0 million compared to $53.9 million and $24.0
million for the years ended December 31, 1996 and 1995, respectively. Although
net income decreased by $9.3 million during 1997, operating cash flow increased
$17.0 million over the prior year. An increase in non-cash expenses of $25.7
million, primarily depreciation and amortization, and an increase in operating
net assets of $0.6 million, primarily increased collection of receivables, were
the key factors driving the change. The increase in operating cash flow of $29.9
million from 1995 to 1996 was driven by an increase in net income of $9.7
million, an increase in operating net assets of $15.6 million and a $4.6 million
increase in non-cash expenses.

         Net cash used in investing activities was $67.1 million in 1997,
compared to $41.9 million in 1996 and $12.4 million in 1995. Cash expenditures
for property and equipment in 1997 (net of proceeds on disposals) were $44.9
million compared to $26.8 million in 1996 reflecting staff increases and general
business growth. In 1995, total net cash used in investing activities of $12.4
million was due to net capital expenditures relating to staff and general
business growth. Cash paid for new businesses acquired was $13.7 million in 1997
compared to $9.5 million in 1996 and cash paid for purchases of minority
interests in other entities was $2.9 million in 1997 compared to $5.5 million in
1996. The Company also purchased intellectual property rights for $6.6 million
during 1997, of which $1.0 million was sold during the period. At December 31,
1997, the Company was committed to investing a maximum of $8.1 million to fund
additional future capital requirements associated with minority interests in
certain investments. In January 1998, the Company sold its entire minority
interest in one investment for $5.1 million and thus eliminated a future capital
commitment of $7.1 million out of the total of $8.1 million at December 31,
1997.



                                      10




<PAGE>   13




         Net cash provided by financing activities of $4.4 million in 1997 was
generated primarily by the sale of stock options to Swiss Bank for $8.1 million
offset in part by payments on capital leases of $3.7 million and net cash
purchases of treasury stock totaling $0.7 million. In 1996, total net cash used
in financing activities was $4.5 million primarily due to an $8.5 million
redemption of preferred stock, payments on capital leases of $2.2 million and
preferred stock dividend payments of $0.9 million, offset partially by proceeds
from the sale of common stock of $4.7 million and repayments of stockholder
notes receivable of $2.2 million.

         Because of growth in its international operations, the Company, in
certain instances, utilizes foreign currency exchange contracts to manage its
exposure and to mitigate the effects of currency fluctuations.

         The Company maintained its existing line of credit of $40.0 million
throughout 1997. Although the Company incurred borrowings up to $34.3 million 
during 1997, no borrowings were outstanding at December 31, 1997.

         The Company anticipates that cash flows from operating activities will
provide sufficient funds to meet its needs during 1998. The Company's existing
line of credit expires July 31, 1998. Although there is no assurance that the
Company can extend its existing line of credit or negotiate a new line of
credit, the Company anticipates that it will not have significant difficulty
extending its existing line of credit or negotiating a new line of credit if the
Company chooses to do so. As new contracts are commenced or existing contracts
expanded, there will be increasing requirements for cash resources to fund
current operations. Significant growth in the Company's business in 1998 and
beyond could result in the need for private or public offerings of debt or
equity instruments of the Company to provide the funds necessary to support its
growth.

         The Company experienced substantial growth in 1996 and 1997. A
significant portion of that growth resulted from the formation of the Company's
strategic alliance with Swiss Bank in January 1996, which was revised in April
1997. During the years ended December 31, 1997 and 1996, approximately 27% and
28%, respectively, of the Company's revenues were earned in connection with
services performed on behalf of Swiss Bank and its affiliates.

                          INDEPENDENT AUDITORS' REPORT


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.

                   PEROT SYSTEMS CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                    ---------



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 to provide systems
         outsourcing, systems integration, software development, consulting, and
         other information technology services. On December 19, 1995, the
         Company reincorporated in the state of Delaware. 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.

         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.

         Revenue recognition

                           Revenue from contracts is generally recognized based
                  on the performance of tasks as defined in the contracts.
                  Revenue and fees on certain cost reimbursable contracts are
                  recognized as costs are incurred. Revenue from certain
                  long-term contracts has been recognized by the
                  percentage-of-completion method of accounting. Provisions for
                  estimated losses on contracts are recorded when identified.
                  Billings for services or products acquired for clients when
                  the Company acts as an agent on behalf of the client are
                  excluded from revenue.

                           Deferred revenue is comprised of payments from 
                  customers 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 $3,243 and $4,486 in 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 or 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
                  $47,033 through 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 $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.

                           The net foreign currency transaction gains/(losses)
                  reflected in other income/(expense) were $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.

                           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

                           Treasury stock transactions are accounted for under
                   the cost method.

         Reclassifications

                           Certain of the 1996 and 1995 amounts in the
                  accompanying financial statements have been reclassified to
                  conform to the current presentation.

         Stock based compensation

                           The Company has elected to follow Accounting
                   Principles Board Opinion No. 25 (APB 25), "Accounting for
                   Stock Issued to Employees", and related interpretations in
                   accounting for its employee stock options. Under APB 25,
                   because the exercise price of employee stock options equals
                   the market price of the underlying stock on the date of
                   grant, no compensation expense is recorded. The Company has
                   implemented the disclosure-only provisions of Statement of
                   Financial Accounting Standards No. 123, "Accounting for Stock
                   Based Compensation".

         Accounting standard issued

                           In June 1997, the Financial Accounting Standards
                   Board issued Statement of Financial Accounting Standards No.
                   130 (SFAS 130), "Reporting Comprehensive Income", effective
                   for fiscal years beginning after December 15, 1997. SFAS 130
                   establishes standards for the reporting and display of
                   comprehensive income and its components in a full set of
                   general-purpose financial statements. The Company has not yet
                   determined the impact, if any, of implementing SFAS 130.

                   Amounts to be invoiced represent revenue contractually

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.

              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:

         </TABLE>

              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.

              At December 31, 1997 and 1996, goodwill of $16,596 and $7,293, net
         of $6,097 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 Swiss
         Bank Corporation as part of a larger services agreement. The Company's
         investment in Systor at December 31, 1997 and 1996 was $7,188 and
         $3,538, respectively.

                                           ---------

              On March 26, 1996, the Company entered into a joint venture with
         HCL Corporation Limited and HCL Europe Limited whereby the Company owns
         49% of HCL Perot Systems NV ("HCL"), an information services company
         based in India. The Company contributed capital of $500 to HCL during
         1997, and is required to contribute additional capital up to a limit of
         $6,900, on a call basis. The Company's investment in HCL at December
         31, 1997 and 1996 was $1,742 and $524, respectively.

              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 was $4,196 and ($312) for 1997 and 1996,
         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. As of December 31,
         1997 and 1996, the Company has made net capital contributions of
         $2,125, 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 867,000 shares of the preferred stock for $400 in June
         1997, representing a total 12.3% equity interest. As part of the
         purchase agreement, the Company is subject to a call option, which, if
         exercised, would require the Company to purchase additional shares for
         a commitment of up to $1,000.

              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.

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 re-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 December 31, 1997. This
         facility expires July 31, 1998.

</TABLE>

         Other contract-related

              Other contract-related accrued liabilities represent provisions to
         match contract-related liabilities 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. 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.

9.       Capital Lease Obligations and Long-Term Debt

              Capital lease obligations and long-term debt consist of the

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

              Class A Common Stock ("Class A") of the Company consists of
         100,000,000 authorized shares of $0.01 par value common stock, of which
         there are 38,227,707 shares issued and outstanding as of December 31,
         1997. The Company is authorized to issue, under its existing stock
         plans, up to 100,000,000 Class A shares, of which 33,082,562 were
         outstanding at year end. In addition, 7,000,000 Class A shares are
         reserved for future conversion of Class B Common Stock ("Class B").

              Class B shares consist of 24,000,000 authorized shares of $0.01
         par value common stock, of which there are 50,000 shares issued and
         outstanding as of December 31, 1997. The Class B shares were authorized
         in conjunction with the provisions of the original Swiss Bank 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 Swiss Bank 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. 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. All
         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.

         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.

         Swiss Bank Agreement

              On April 24, 1997, the Company concluded the renegotiation of the
         terms of its strategic alliance with Swiss Bank, 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 SBC Warburg ("SBC Warburg EPI
         Agreement"), (ii) separate agreements to provide IT services to other
         Swiss Bank operating units and to permit the Company to use certain
         Swiss Bank assets, (iii) the sale to Swiss Bank of options to acquire
         shares of the Company's Class B stock, (iv) the sale to Swiss Bank 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 Swiss Bank agreements. The Company
         continues to hold a 40% stake in Systor. In the event of termination of
         the SBC Warburg EPI Agreement, a portion of the Company's interest in
         Systor would be returned to Swiss Bank, declining ratably over the
         10-year period which began on January 1, 1997.

              The new terms of the SBC Warburg EPI Agreement require the Company
         to provide operational management for SBC Warburg's 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 SBC 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 Swiss Bank options to purchase 3,617,160 shares of the
         Company's Class B stock at a cash non-refundable 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 Swiss Bank 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

         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

         29,167 shares per month thereafter. In the event of termination of the
         SBC 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.

              The Company also agreed to issue and sell to Swiss Bank 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 Swiss
         Bank deems appropriate, provided the Company and Swiss Bank, 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 SBC 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 1965 and subsequent
         regulations and interpretations put forth by the Federal Reserve Board
         (the "regulations"), Swiss Bank's holdings in terms of shares of the
         Company's common stock may not reach or exceed 10% of the total of all
         classes of the Company's common stock. Similarly, the total
         consideration paid by Swiss Bank for the purchase of shares plus the
         purchase and exercise of options may not at any time reach or 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
         Swiss Bank's options are exercisable, is limited due to an insufficient
         number of shares outstanding, Swiss Bank 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 Swiss Bank for authorization
         to exceed its allowable percentage of ownership, or (iii) the purchase
         of Class B shares by the Company from Swiss Bank 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 Swiss Bank is unable to
         exercise its options as a result of the regulations.

              As previously noted, the Company has continued to account for its
         stock option activity under APB 25. Had the Company elected to adopt
         SFAS 123, the pro forma impact on net income and earnings per share
         would have been as follows:

         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.

              A valuation allowance has not been established for the net
        deferred tax asset as of December 31, 1997 or 1996, due to a
        significant contract backlog and the availability of loss carrybacks.

              The provision for income taxes differs from the amount of income
        tax determined by applying the applicable U.S. statutory federal income
        tax rate to income before taxes, as a result of the following
        differences:

13.      Commitments and Contingencies

         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 as
              follows:

                   The Company is obligated under certain operating leases for
              its pro rata share of the lessors' operating expenses. Rent
              expense was $17,958, $18,212, and $23,731 for 1997, 1996 and 1995,
              respectively.

         Letter of credit

                   The Company had a $1,000 irrevocable letter of credit as of
              December 31, 1997. The letter of credit was issued in conjunction
              with the provisions of a certain contract. The fair value of the
              letter of credit is estimated to be equal to the face value based
              on the nature of the fee arrangements with the issuing bank.

         Financial instruments with off-balance sheet risk

              Interest rate swap

                   In December 1993, the Company entered into an agreement with
              a customer 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

                  PEROT SYSTEMS CORPORATION AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 -----------
                                                                          
              Company is required to make an interest sensitive payment to
              the customer if a defined variable interest rate ("Rate") exceeds
              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 is less than 8.5%, the customer is
              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 is 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 are 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 is risk of default by the customer or the bank,
              which the Company believes to be remote.

              Foreign currency exchange forward contracts

                  At December 31, 1997, the Company had three forward exchange
              contracts maturing in early 1998. Two British pound to U.S. dollar
              trades for $10,177 and $6,684 as of December 31, 1997 mature in
              February 1998 and January 1998, respectively. A third forward
              trade of Swiss franc to U.S. dollar totaling $8,108 matures in
              January 1998.

                  The estimated fair value of the Company's forward exchange
              contracts using bank or market quotes and the year end foreign
              exchange rates was 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
              1,463,376 shares of Class A Common Stock are subject to contingent
              put rights. 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 540,000 of these shares, 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.

         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 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. Based on such
              assessment, the Company does not believe that its client
              obligations with respect to the Year 2000 issue will have a
              material adverse impact on the financial position and results of
              operations of the Company.

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 years ended
         December 31, 1997, 1996 and 1995 amounted to $7,388, $4,785 and $1,919,
         respectively. The Company's contribution of common stock for the years
         ended December 31, 1997, 1996 and 1995 totaled 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
         $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 and 1997, certain officers financed the purchase of
         Class A Common Stock with a bank. In addition, the Company entered into
         an agreement with this bank under which, if the Company's Class A
         common shares are not publicly traded prior to the earlier of June 30,
         1998 or the maturity date of the individual loans, the Company would
         purchase, at the bank's option, any of these loans. As of December 31,
         1997, approximately $1,546 remain outstanding under these loans. All of
         these loans bear interest at the prime rate plus 1% (currently 9.5%)
         and are due at various dates between July 1, 1998 and July 22, 1999.

              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 common 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 December 31, 1997, the principal balance remaining on these notes
         is $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 common
         shares are not publicly traded prior to the earlier of June 30, 1998 or
         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 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
         common 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 common shares held by the executive and are due by
         December 31, 1999.

              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.

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 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.

                           RESTRICTED STOCK AGREEMENT





THIS AGREEMENT, dated as of December 22, 1995, is by and between Perot Systems
Corporation ("Perot Systems"), a Delaware corporation and Morton H. Meyerson
("Participant").

                                  WITNESSETH:

WHEREAS, Perot Systems has adopted the Perot Systems Corporation Restricted
Stock Plan (the "Plan") to enable employees of Perot Systems and its
subsidiaries to acquire shares of Common Stock, $0.01 par value, of Perot
Systems ("Common Stock") in accordance with the provisions of the Plan; and

WHEREAS, the Restricted Stock Committee of Perot Systems (the "Committee") has
selected Participant to participate in the Plan and granted Participant the
right to purchase shares of Common Stock in accordance with the terms and
conditions of this Agreement;

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises
and other terms and conditions set forth in this Agreement, Perot Systems and
Participant agree as follows:

1.       Purchase and Sale. Subject to the terms, conditions, and restrictions
         set forth in this Agreement, Perot Systems hereby sells to
         Participant, and Participant hereby purchases from Perot Systems, for
         a purchase price of $1.75 per share payable contemporaneously with the
         execution hereof, 200,000 shares of Common Stock (such shares,
         together with any successor security, property or cash issued or
         distributed by Perot Systems or any successor entity, whether by way
         of merger, consolidation, share exchange, reorganization, liquidation,
         recapitalization, dividend or otherwise on such shares, the
         "Restricted Stock").

2.       Stock Repurchase.

                 (a)      Subject to Section 2(e) below, if (A) Participant
         voluntarily resigns from his position as a Director of Perot Systems
         and if Participant and Perot Systems do not reach a mutually agreeable
         arrangement for Participant to remain with Perot Systems or (B) the
         SBC Event has not occurred by September 1, 1996 (the first such event
         to occur the "Repurchase Event"), Perot Systems shall have the right
         to repurchase from the Buyer the Unvested Stock (as defined below) for
         the Repurchase Amount (as defined below) (the "Repurchase").

                 (b)      Upon the occurrence of the Repurchase Event, Perot
         Systems shall have 30 days to give written notice (the "Repurchase
         Notice") to the Buyer of Perot Systems' decision to cause the
         Repurchase. The Repurchase Notice shall state the number of the
         Unvested Stock (as defined below). Subject to Section 2(c) below, the
         Buyer shall then have 30 days to deliver to Perot Systems stock
         certificates representing the number of




                        1
<PAGE>   2
         shares of the Unvested Stock in exchange for the payment by Perot
         Systems to the Buyer of the Repurchase Amount, with payment to be made
         by check or wire transfer of same-day funds.

                 (d)      For purposes of this Section 2, the following terms
         shall be defined as set forth below:

                                  (i)      "SBC Event" means the occurrence of
                 both (1) the execution by Perot Systems Corporation or its
                 subsidiary and Swiss Bank Corporation or its subsidiary of the
                 SBC Warburg EPI Agreement in substantially the form as
                 provided in the December 21, 1995 draft, with such changes
                 thereto as the officer executing the same for Perot Systems
                 may deem appropriate, such appropriateness to be conclusively
                 evidenced by such officer's signature thereto, and (2) to the
                 extent that such SBC Warburg EPI Agreement contains a
                 provision specifically permitting Swiss Bank Corporation to
                 unwind such agreement before September 1, 1996 if approval of
                 the Board of Governors of the Federal Reserve System is not
                 obtained, then the expiration of such period as provided in
                 the agreement without such an unwind, or earlier if such
                 consent is obtained.


                                  (ii)     "Repurchase Amount" means the
                 product of (i) number of the Unvested Stock and (ii) the sum
                 of $1.75 and interest on such $1.75 at an interest rate of 8%
                 per annum, compounded annually, and computed from the date of
                 this Agreement to the date of the Repurchase.

                                  (iii)    "Unvested Stock" means a number of
                 shares of Perot Systems' common stock equal to the product of
                 (a) 200,000 minus the number of shares of Restricted Stock
                 purchased hereunder that Participant transfers to affiliates
                 (who may be affiliated by marriage) of employees or
                 consultants of Perot Systems or its subsidiaries after the SBC
                 Event and (b) 1 minus the quotient of the number of full
                 months that Participant remains as a Director of Perot Systems
                 commencing on the Effective Date, divided by sixty months,
                 provided that the number of the Unvested Stock shall never be
                 less than zero (0).

                                  (iv)     "Vested Stock" means the Restricted
                 Stock minus the Unvested Stock.

                 (e)      Notwithstanding anything in this Section 2 to the
         contrary, Participant shall not have voluntarily resigned from Perot
         Systems if his decision to resign from Perot Systems (or his inability
         to continue to serve Perot Systems in such capacity) is caused by one
         or more of the following events:

                                  (i)      the death or disability of
                 Participant or the termination of Participant by Perot Systems
                 from his position as a Director (and disability shall occur
                 upon the mental or physical disability of Participant that
                 will permanently prevent Participant from performing his
                 duties for Perot Systems);

                 services to the U.S. government or an agency thereof or one
                 working for such government or agency and after consulting
                 with Participant, Perot Systems' Board of Directors agrees to
                 permit Participant to leave his position a Director of Perot
                 Systems;

                                  (iii)    Participant is constructively
                 terminated from his position, such as being assigned tasks to
                 perform work not suitable for a Director;

                                  (iv)     Perot Systems requests Participant
                 to relocate from the City of Dallas;

                                  (v)      Perot Systems demands excessive
                 travel from Participant;

                                  (vi)     Perot Systems, its Board of
                 Directors, or one of Perot Systems' officers requests
                 Participant to engage in any conduct that is not moral or
                 ethical or in violation of law; or

                                  (vii) the Board of Directors of Perot Systems
                 makes a major change in corporate policy or has decided that
                 Perot Systems should engage in a significant corporate
                 development or transaction and Participant has voted against
                 such decision or Participant is not present at the meeting
                 where the decision is made; provided that (a) Participant has
                 delivered written notice to each of the members of the Board
                 of Directors within 5 days of the date of the Board decision
                 (or if Participant is not present at the meeting when the
                 decision is made, within 5 days of notice from the Board to
                 him of its decision), requesting the Board to reverse its
                 decision and informing the Board that he intends to resign
                 because of such decision and (b) the Board has not reversed
                 its decision and so informed Participant within 30 days of
                 the receipt of the notice given by Participant. This provision
                 will not apply to the refusal by the Board of Directors to
                 approve a policy, development or transaction recommended by
                 Participant.

3.       Compliance with Securities Laws. Participant hereby represents and
         warrants that Participant has acquired the Restricted Stock for
         Participant's own account and not with a view to any resale or
         distribution thereof.  Participant agrees that neither he nor any
         subsequent holder of the Restricted Stock will sell or otherwise
         transfer any shares of Restricted Stock in any way that may result in
         a violation of any federal or state securities laws or regulations.
         Participant further acknowledges and agrees that Perot Systems may
         require any subsequent purchaser or other transferee of shares of
         Restricted Stock that cannot be publicly traded to provide Perot
         Systems, prior to such sale or other transfer, with such
         representations, commitments and opinions regarding compliance with
         applicable securities laws and regulations as Perot Systems may deem
         necessary or advisable.

4.       Stock Certificate. If requested by Participant, Perot Systems will
         issue and deliver to Participant certificates representing any shares
         of Vested Stock held by Participant. Perot


                        3
<PAGE>   4
         Systems may require that any certificates or other property
         representing shares of Unvested Stock remain in the possession of
         Perot Systems or an escrow agent designated by the Committee. Each
         certificate representing Vested Stock or Unvested Stock shall bear
         such legends as the Committee may determine to be necessary or
         appropriate. Whether or not certificates representing such shares have
         been issued or delivered, Participant shall have all the rights of a
         shareholder of Restricted Stock, including voting, dividend and
         distribution rights, with respect to all shares of Restricted Stock,
         both Vested Stock and Unvested Stock, held by Participant, but any and
         all stock and/or cash dividends (other than normal periodic cash
         dividends), distributions in property, or other distributions made on
         or in respect of the Restricted Stock, whether resulting from a
         subdivision, combination or reclassification of the Restricted Stock
         of any issuer thereof or received in exchange for Restricted Stock or
         any part thereof or as a result of any merger, consolidation,
         acquisition or other exchange of assets to which any such issuer may
         be a party or otherwise, and any and all cash and other property
         received in exchange for the Restricted Stock or received in payment
         of the principal of or in redemption of the Restricted Stock (either
         at maturity, upon call for redemption or otherwise), shall remain in
         the possession of Perot Systems for Unvested Stock.

5.       Income Tax Withholding.  Participant acknowledges and agrees that
         Participant shall, upon request by Perot Systems from time to time,
         reimburse Perot Systems for, or Perot Systems may withhold from sums
         otherwise payable to Participant, any amounts Perot Systems is
         required to remit to applicable taxing authorities as income tax
         withholding with respect to the Restricted Stock. If Participant fails
         to reimburse Perot Systems for any such amount when requested, Perot
         Systems shall have the right to recover that amount by selling
         sufficient shares of Participant's Unvested Stock.

6.       Compliance with Plan. Participant acknowledges that this Agreement is
         entered into, and the Restricted Stock is issued, pursuant to the Plan
         and agrees to comply with the provisions of the Plan, as it may be
         amended from time to time, to the extent that such provisions are not
         inconsistent with the provisions of this Agreement.

7.       Notices. Any notice to Perot Systems or Company that is required or
         permitted by this Agreement shall be addressed to the attention of the
         Secretary of Perot Systems at its principal office. Any notice to
         Participant that is required or permitted by this Agreement shall be
         addressed to Participant at the most recent address for Participant
         reflected in the appropriate records of Perot Systems. Either party
         may at any time change its address for notification purposes by giving

                                PROMISSORY NOTE


                                                                January 28, 1997
$187,500

FOR VALUE RECEIVED, TERRY M. ASHWILL ("Associate"), promises to pay to Perot
Systems Corporation, a Delaware corporation (the "Company"), or order, at the
principal offices of the Company or at such other place as the holder of this
Note may designate, the principal sum of $187,500 payable, along with interest
calculated at eight percent per annum (8%), on or before JANUARY 28, 2000, or
earlier if otherwise required pursuant to the terms of this Note. Interest,
unless required to be paid earlier pursuant to the terms of this Note, will be
payable annually, beginning JANUARY 28, 1998.

In order to facilitate the making of payments due on this Note, Associate
hereby requests the Company to make semi-monthly payroll deductions, each in
the amount of $625.00, from any amount owed to him on or about the 15th and the
last day of each month. The amounts so received will be debited against
interest due under this Note.

         The Company has the right to offset amounts due under this Note
against payroll payments to be made by the Company to Associate.

         This Note shall become immediately due and payable in full without
notice or demand upon the earlier of (i) termination of Associate's employment
with the Company or any subsidiary of the Company, for any reason, with or
without cause, or (ii) three months after the restrictions on transfer of
vested common stock set forth in Section 3(d) of the Restricted Stock Agreement
of even date herewith between Associate and Company lapse. In addition, if
Associate sells any of the Company common stock purchased in connection with
the issuance of this Note, Associate shall, within thirty days of such sale,
prepay this Note to the extent of the net proceeds of such sale, less any
income taxes payable by Associate with respect to income derived from such
sale.

         Payment of this Note is secured pursuant to a Pledge Agreement of even
date herewith between PSC and Associate (the "Pledge Agreement").

         Nothing in this Note shall confer upon Associate any right to continue
in the employ of the Company or any subsidiary of the Company or interfere in
any way with the right of the Company or any subsidiary of the Company to
terminate such employment at any time.

         Every amount overdue under this Note shall bear interest from and
after the date on which such amount first became overdue at an annual rate
(compounded annually) which is the lesser of (a) two percentage points above
the rate designated from time to time by NationsBank of Texas as its prime
lending rate or (b) the maximum amount permitted by law. Such interest on
overdue amounts under this Note shall be payable on demand and shall accrue
until the obligation of Associate with respect to the payment of such interest
has been discharged (whether before or after judgment).

         In no event shall any interest charged, collected or reserved under
this Note exceed the maximum rate then permitted by applicable law and if any
such payment is paid by Associate, then such excess sum shall be credited by
the holder as a payment of principal.

         All payments by Associate under this Note shall be made without
set-off or counterclaim and be free and clear and without any deduction or
withholding for any taxes or fees of any nature whatever, unless the obligation
to make such deduction or withholding is imposed by law.


<PAGE>   2
         Associate agrees to pay on demand all costs of collection, including
reasonable attorneys' fees, incurred by the holder in enforcing the obligations
of Associate under this Note.

         No delay or omission on the part of the holder in exercising any right
under this Note or the Pledge Agreement under which the Restricted Stock is
pledged shall operate as a waiver of such right or of any other right of such
holder, nor shall any delay, omission or waiver on any one occasion be deemed a
bar to or waiver of the same or any other right on any future occasion.
Associate hereby waives presentment, demand, protest and notices of every kind
and assents to any extension or postponement of the time of payment or any
other indulgence, to any substitution, exchange or release of collateral, and
to the addition or release of any other party or person primarily or
secondarily liable.

         This Note may be prepaid in whole or in part at any time or from time
to time in the sole discretion of the holder. Any such prepayment shall be
without premium or penalty.

         None of the terms or provisions of this Note may be waived, modified
or amended except by a written instrument duly executed on behalf of the holder
expressly referring to this Note and setting forth the provision so waived,
modified or amended.

         All rights and obligations hereunder shall be governed by the laws of
the State of Texas. Any action to enforce the provisions of, or otherwise
relating to, this Note may be brought in the appropriate courts in Dallas
County, Texas.

                                PLEDGE AGREEMENT


         This Pledge Agreement (the "Agreement") is made as of January 28,
1997, by and between Perot Systems Corporation, a Delaware corporation ("PSC"),
and Terry M. Ashwill ("Pledgor").

         WHEREAS, PSC has granted Pledgor the option to purchase 100,000 shares
of PSC's Class A common stock pursuant to a Restricted Stock Agreement dated as
of January 28, 1997 (the "Restricted Stock Agreement");

         WHEREAS, PSC has extended credit to Pledgor and may extend additional
credit pursuant to the terms of a Promissory Note and a Bridge Note, each of
which is dated as of the date hereof and is in the amount of $187,500, for a
total of $375,000, to finance the acquisition of the Restricted Stock purchased
pursuant to the Restricted Stock Agreement (together the "Notes");

         NOW, THEREFORE, to secure the Obligations (as defined below), Pledgor
and PSC hereby agree as follows:

         1.      Definitions. Capitalized terms that are not otherwise defined
in this Agreement have the meanings assigned to such terms in the Restricted
Stock Agreement or the Notes, as appropriate.

         2.      Pledge of Securities. Pledgor hereby pledges and grants to PSC
a security interest in the following:

                 (a)      the Restricted Stock purchased by Pledgor pursuant to
         the Restricted Stock Agreement, together with any other shares of
         capital stock of PSC that may be distributed with respect to such
         Restricted Stock (collectively, the "Securities"), and all rights and
         privileges pertaining thereto;

                 (b)      all proceeds, products, cash, securities, dividends,
         increases, distributions and profits received from or on the
         Securities (the "Proceeds"), including without limitation
         distributions or payments in partial or complete liquidation or
         redemption, or as a result of reclassifications, readjustments,
         reorganizations or changes in the capital structure of the issuer of
         the Securities; and

                 (c)      all subscriptions, warrants, options, preemptive
         rights and other rights issued or otherwise granted by the issuer of
         the Securities or any other person on or in connection with the
         Securities or any other item of the Collateral (as defined below);

         (all of such property and rights described in items (a), (b) and (c)
         above are herein collectively called the "Collateral");

                                     Page 1
<PAGE>   2
TO HAVE AND TO HOLD the Collateral, together with all rights, titles,
interests, privileges and preferences appertaining to or incidental thereto,
unto PSC, and its respective successors and assigns, forever, subject, however,
to the terms, covenants and conditions hereinafter set forth. The security
interest granted and the assignments made hereunder are made as security only
and shall not subject PSC to, or transfer or in any way affect or modify, any
obligation of Pledgor with respect to any of the Collateral or any transaction
involving or giving rise thereto.

         3.      Obligations Secured. The pledge and security interest in the
Collateral granted hereby secures payment and performance of the following
obligations of Pledgor to PSC, whether now outstanding or incurred after the
date hereof (the "Obligations"): (a) all principal, interest, fees, expenses,
obligations and liabilities of Pledgor arising pursuant to or represented by
the Notes; (b) all taxes, assessments, insurance premiums, brokerage fees,
reasonable attorneys' fees and other expenses of sale of the Collateral; (c)
Pledgor's performance of his obligations under the Notes, this Agreement and
the Restricted Stock Agreement; and (d) all renewals, extensions and
modifications of the indebtedness and obligations referred to in the foregoing
clauses, or any part thereof.

         4.      Pledgor's Warranties and Indemnity. Pledgor represents,
warrants and covenants to PSC (a) that Pledgor is and will be the lawful owner
of the Securities, (b) that the Securities are and will remain free and clear
of all liens, encumbrances and security interests other than the security
interest granted by Pledgor hereunder, and (c) that Pledgor has the right and
authority to pledge the Securities and otherwise to comply with the provisions
hereof. If any adverse claim is asserted in respect of the Securities or any
portion thereof, except such as may result from an act of PSC not authorized
hereunder, Pledgor shall indemnify PSC and hold PSC harmless from and against
any losses, liabilities and expenses (including reasonable counsel fees)
incurred by PSC in exercising any right, power or remedy of PSC hereunder or
defending, protecting or enforcing the security interests created hereunder.
Any such loss, liability or expense so incurred shall be paid by Pledgor upon
demand, and shall become part of the Obligations of Pledgor secured pursuant to
this Agreement. Pledgor agrees to execute a stock power in blank for each
certificate evidencing any of the Securities and to deliver all such Securities
certificates with stock powers to PSC. PSC hereby consents to the pledge of the
Securities to PSC hereunder, notwithstanding any restrictions on transfer of
the Securities set forth in the Restricted Stock Agreement.

         5.      Negative Covenants. Pledgor covenants and agrees that, unless
PSC otherwise consents in writing Pledgor will not: (a) sell, assign or
transfer any rights of Pledgor in the Collateral; or (b) create any lien in, or
security interest in, or otherwise encumber, the Collateral, or any part
thereof, or permit the same to be or become subject to any lien, attachment,
execution, sequestration, other legal or equitable process, or any encumbrance
of any kind or character, except the security interest herein created in favor
of PSC.

         6.      Dividends and Other Distributions.

                          (a) Pledgor shall cause all non-cash dividends and
                 distributions with respect to the Securities (including
                 without limitation any stock dividends and any distributions
                 made on or in respect of the Securities, whether resulting
                 from a subdivision,

                                     Page 2
<PAGE>   3

                 combination or reclassification of the Securities or received
                 in exchange for or in respect of the Securities or any part
                 thereof or as a result of any merger, consolidation,
                 acquisition or other transaction) to be distributed directly
                 to PSC, to be held by PSC as additional Collateral; and if any
                 such distribution is made to Pledgor, he shall receive such
                 distribution in trust for PSC and shall immediately transfer
                 it to PSC.

                          (b)     So long as no Event of Default or Potential
                 Default has occurred and is continuing, Pledgor shall be
                 entitled to receive any cash dividends payable in respect of
                 the Securities; provided that, upon receipt of any such cash
                 dividend, Pledgor will promptly (and in any event within 30
                 days) pay to PSC in respect of the Obligations (to the extent
                 of the Obligations then outstanding) the full amount of such
                 cash dividend less any income taxes payable by Pledgor as a
                 result of such cash dividend, and, pending such payment, such
                 cash dividend will continue to constitute Collateral
                 hereunder.

         7.      Voting Rights. So long as no Event of Default or Potential
Default has occurred and is continuing, Pledgor shall be entitled to exercise
any and all voting rights pertaining to the Securities for any purpose not
inconsistent with the terms of the Notes or this Agreement.

         8.      Termination of Rights. During any period when an Event of
Default has occurred and is continuing, all rights of Pledgor to receive
dividends pursuant to Section 6(b) or to exercise voting rights pursuant to
Section 7 shall cease and all such rights shall thereupon become vested in PSC,
which shall have the sole and exclusive right and authority to dispose of the
Securities and to receive dividends and exercise voting rights in respect of
the Securities.  Further, PSC shall have the right, during the continuance of
any Event of Default, to notify and direct the issuer of the Securities to make
all payments, distributions, dividends and any other distributions payable in
respect thereof directly to PSC. The issuer of the Securities making any
payment or distribution to PSC hereunder shall be fully protected in relying on
the written statement of PSC that it then holds a security interest that
entitles PSC to receive such payments and distributions. Any and all money and
other property paid over to or received by PSC pursuant to the provisions of
this Section 8 shall be retained by PSC as additional collateral hereunder and
may be applied in accordance with the provisions hereof.

         9.      Rights and Remedies of PSC Upon and After Default.

                          (a)     Remedies. Upon the occurrence of an Event of
                 Default, and in addition to any and all other rights and
                 remedies which PSC may then have under this Agreement, the
                 Restricted Stock Agreement, the laws of the United States or
                 the Uniform Commercial Code, as then in effect in Texas (the
                 "Code"), or otherwise, PSC may: (i) declare the entire unpaid
                 balance of principal of and all accrued interest on the
                 Obligations immediately due and payable, without notice
                 (including notice of intention to accelerate and notice of
                 acceleration) except as required under the Notes, demand or
                 presentment, which are hereby waived; (ii) reduce its claim to
                 judgment, foreclose or otherwise enforce its security interest
                 in all or any part of the Obligations by any available
                 judicial procedure; (iii) after notification, if any,
                 expressly provided for herein, sell or otherwise dispose of,
                 at the office of PSC, or elsewhere as chosen by PSC, all or

                                     Page 3
<PAGE>   4
                 any part of the Collateral, and any such sale or other
                 disposition may be as a unit or in parcels, by public or
                 private proceedings, and by way of one or more contracts, (it
                 being agreed that the sale of any part of the Collateral shall
                 not exhaust the power of sale granted hereunder, but sales may
                 be made from time to time until all of the Collateral has been
                 sold or until the Obligations have been paid in full), and at
                 any such sale it shall not be necessary to exhibit the
                 Collateral; (iv) at PSCs discretion, retain the Collateral in
                 satisfaction of the Obligations whenever the circumstances are
                 such that PSC is entitled to do so under the Code; (v) apply
                 by appropriate judicial proceedings for appointment of a
                 receiver for the Collateral, or any part thereof, and Pledgor
                 hereby consents to any such appointment; (vi) purchase the
                 Collateral at any public sale; (vii) purchase the Collateral
                 at any private sale if permitted by the Code; and/or (viii)
                 exercise the rights set forth in Section 10 hereof.

                          (b)     Sale of Securities. Pledgor recognizes that
                 PSC may be unable to effect a public sale of any or all of the
                 Securities by reason of certain prohibitions contained in the
                 federal securities laws and applicable state or foreign
                 securities laws, and thus may resort to one or more private
                 sales thereof to a restricted group of purchasers who will be
                 obliged to agree, among other things, to acquire such
                 securities for their own account for investment and not with a
                 view to the distribution or resale thereof. Pledgor
                 acknowledges and agrees that any such private sale may result
                 in prices and other terms less favorable to the seller than if
                 such sale were a public sale and, notwithstanding such
                 circumstances, agrees that any such private sale shall be
                 deemed to have been made in a commercially reasonable manner.
                 PSC shall be under no obligation to delay a sale of any of the
                 Securities for the period of time necessary to permit the
                 issuer of such securities to register such securities for
                 public sale under the federal securities laws, or under
                 applicable state securities laws, even if such issuer would
                 agree to do so. Upon the consummation of any private or public
                 sale, PSC shall have the right to deliver, assign, and
                 transfer to the purchaser thereof the Securities so sold. Each
                 purchaser at any such sale shall hold the property sold
                 absolutely free from any claim or right of whatsoever kind,
                 and Pledgor hereby waives (to the extent permitted by law) all
                 rights of redemption, stay and/or appraisal which it has or
                 may at any time in the future have under any rule of law or
                 statute now existing or hereafter enacted. PSC shall give
                 Pledgor notice of PSC's intention to make any such public or
                 private sale at broker's board or on a securities exchange to
                 the extent required hereunder or by the Code.  Such notice, in
                 case of sale at broker's board or on a securities exchange,
                 shall state the board or exchange at which such sale is to be
                 made and the day on which the Securities, or that portion
                 thereof so being sold, will first be offered for sale at such
                 board or exchange. At any such sale the Securities may be sold
                 in one lot as an entirety or in separate parcels, as PSC may
                 determine. PSC shall not be obligated to make any such sale
                 pursuant to any such notice if PSC shall determine not to do
                 so, regardless of the fact that notice of sale of the
                 Securities may have been given. PSC may without notice or
                 publication, adjourn any public or private sale or cause the
                 same to be adjourned from time to time by announcement at the
                 time and place fixed for the sale, and such sale may be made
                 at any time or place to which the same may be so adjourned. In
                 case of any sale of all or any part of the Securities on
                 credit or for future delivery, the Securities so sold may be


                                     Page 4
<PAGE>   5
                 retained by PSC until the selling price is paid by the
                 purchaser thereof, but PSC shall not incur any liability in
                 case of the failure of such purchaser to take up and pay for
                 the Securities so sold and, in case of any such failure, such
                 Securities may again be sold upon like notice. PSC may also,
                 at its discretion, proceed by a suit or suits at law, or in
                 equity to foreclose its security interest and sell the
                 Securities, or any portion thereof, under a judgment or decree
                 of a court or courts of competent jurisdiction. If any
                 consent, approval or authorization of any state, municipal or
                 other governmental department, agency or authority should be
                 necessary to effectuate any sale or other disposition of the
                 Securities or any part thereof, Pledgor shall execute all such
                 applications and other instruments as may be required in
                 connection with securing any such consent, approval or
                 authorization, and will otherwise use Pledgor's best efforts
                 to secure the same.

                          (c)     Notification. Reasonable notification of the
                 time and place of any public sale of the Collateral, or
                 reasonable notification of the time after which any private
                 sale or other intended disposition of the Collateral is to be
                 made, shall be sent to Pledgor and to any other person
                 entitled under the Code to notice; provided, that if the
                 Collateral threatens to decline quickly in value, or if
                 otherwise permitted by the Code, PSC may (but shall not be
                 obligated to) sell or otherwise dispose of the Collateral
                 without notification, advertisement or other notice of any
                 kind. It is agreed that notice sent or given not less than ten
                 calendar days prior to the taking of the action to which the
                 notice relates is reasonable notification and notice for the
                 purposes of this section.

                          (d)     Application of Proceeds. Upon the maturity of
                 the Obligations or any part thereof, whether such maturity be
                 by such terms of such instruments or through the exercise of
                 any power of acceleration, PSC is authorized and empowered to
                 apply any and all funds realized from the sale of the
                 Collateral not previously credited against the Obligations
                 first toward the payment of the costs, charges and expenses,
                 if any, incurred in connection with the collection of such
                 funds hereunder, and then toward the payment of the
                 Obligations in such order as PSC, in its sole discretion,
                 shall deem appropriate, and shall pay the balance remaining
                 (if any) to Pledgor as prescribed by the Code or as a court of
                 competent jurisdiction may direct.

         10. Attorney-in-Fact. Pledgor hereby appoints PSC as the
attorney-in-fact for Pledgor for the purpose of carrying out the provisions of
this Agreement and taking any action and executing any instrument which PSC may
deem necessary or advisable to accomplish the purposes hereof, which
appointment is irrevocable and coupled with an interest.  Without limiting the
generality of the foregoing, PSC shall have the right and power to receive,
endorse and collect all checks and other orders for the payment of money made
payable to Pledgor and included within the Collateral and to give full
discharge for the same. Neither PSC nor any director or officer of the issuer
of the Securities shall have any liability for the distribution to and
collection of the Proceeds by PSC, but shall be fully protected in relying on
the written statement of PSC as to its authorization pursuant to this
paragraph. Any and all amounts collected by PSC pursuant hereto shall be
applied against the Obligations in the manner that PSC shall determine, in
PSC's sole and absolute discretion.

         11.     Certain Other Rights of PSC.

                 (a)      Duty of Care. PSC's only duty with respect to the
         Collateral shall be to exercise reasonable care to secure the safe
         custody thereof. PSC shall not have a duty to fix or preserve rights
         against prior parties to the Collateral, and shall never be liable for
         its failure to use diligence to collect any amount payable with
         respect to the Collateral, but shall be liable only to the account of
         Pledgor for what PSC may actually collect or receive thereon.

                 (b)      Financing Statement. PSC shall have the right at any
         time to execute and file this Agreement or a copy of this Agreement as
         a financing statement, but the failure of PSC to do so shall not
         impair the validity or enforceability of this Agreement.

                 (c)      Payment of Expenses. At PSC's option, PSC may
         discharge taxes, liens and interest, perform or cause to be performed,
         for and on behalf of Pledgor, any actions and conditions, obligations
         or covenants which Pledgor has failed or refused to perform and may
         pay for the repair, maintenance or preservation of any of the
         Collateral, and all sums so expended, including, but not limited to,
         attorneys' fees, court costs, agents' fee or commissions, or any other
         costs or expenses, shall bear interest from the date of payment at the
         highest legal rate and shall be deemed to constitute part of the
         Obligations secured by this Agreement.

         12.     Cumulative Rights and Remedies. All rights and remedies of PSC
hereunder are cumulative of each other and of every other right or remedy which
PSC may otherwise have at law or in equity or under any other contract or other
writing for the enforcement of the security interest herein or the collection
of the Obligations, and the exercise by PSC of one or more rights or remedies
shall not prejudice or impair the concurrent or subsequent exercise of other
rights or remedies. Should Pledgor have heretofore executed or hereafter
executed any other security agreement in favor of PSC in which a security
interest is created as security for the debts of another or others, in respect
of which Pledgor may not be personally liable, the security interest therein
created and all other rights, powers and privileges vested in PSC by the terms
thereof shall exist concurrently with the security interest created herein,
and, in addition, all property in which PSC holds a security interest under any
such other security agreement shall also be part of the Collateral hereunder,
and all or any part of the proceeds of the sale or other disposition of such
property may, in the discretion of PSC, be applied by PSC in accordance with
the terms hereof, and of such other security agreement, or agreements, or any
of them.

         13.     Termination. Upon payment in full by Pledgor of all
Obligations in accordance with their terms, this Agreement shall terminate and
PSC shall return to Pledgor all certificates evidencing the Securities (and any
related stock powers) then held under this Agreement.

         14.     Repurchase Option. If PSC exercises its right to cancel or
repurchase any of the Securities under the Restricted Stock Agreement, PSC
shall be entitled to release such Securities from the pledge under this
Agreement and cancel or repurchase such Securities in accordance with the terms
of the Restricted Stock Agreement.

         15.     Further Assurances. Pledgor agrees to execute and deliver such
further instruments and take such further actions as PSC may reasonably request
from time to time to preserve or give effect to its rights under this
Agreement.

         16.     Action by PSC. Any election, consent, waiver or other action
that may be taken by PSC hereunder will be taken by the Chairman of the Board,
unless Pledgor is then serving in such capacity, in which case such action will
be taken by the Board.

         17.     Notices. Any notice to PSC that is required or permitted by
this Agreement must be addressed to PSC at its principal office to the
attention of the President, with a copy to the General Counsel. Any notice to
Pledgor that is required or permitted by this Agreement must be addressed to
Pledgor at the most recent address for Pledgor reflected in the appropriate
records of PSC. Either party may at any time change its address for
notification purposes by giving the other prior written notice of the new
address and the date upon which it will become effective. Whenever this
Agreement requires or permits any notice from one party to another, the notice
must be in writing and must be sent by courier, overnight delivery service,
facsimile or certified mail, return receipt requested, and such notice will be
deemed to be given (a) if sent by courier, on the date actually delivered, (b)
if sent by overnight delivery service, one day after being sent, (c) if sent by
telecopy, on the date that confirmation of transmission is received by the
sender, or (d) if sent by certified mail, on the third business day after being
mailed.

         18.     Enforcement. This Agreement will be governed by and construed
in accordance with the laws of the State of Texas, without regard to the choice
of law rules thereof. PSC will be entitled, in addition to any other remedies
it may have at law or in equity, to temporary and permanent injunctive and
other equitable relief to enforce the provisions of this Agreement. Any action
to enforce the provisions of, or otherwise relating to, this Agreement may be
brought in the appropriate courts in Dallas, Dallas County, Texas, and Pledgor
hereby consents to the personal jurisdiction of such courts in any such action;
provided that, at the request of PSC or Pledgor, any claim or dispute arising
out of or relating to this Agreement or Pledgor's employment by PSC or the
termination of such employment, including any federal or state statutory
claims, will be resolved without resort to the courts solely through mediation
and, if mediation is not successful, through binding arbitration pursuant to
the rules of the American Arbitration Association. Neither party will be liable
to the other for punitive damages for any such claim or dispute. If any action
at law or in equity is necessary to enforce or interpret the terms of this
Agreement, the prevailing party will be entitled to reasonable attorneys' fees,
costs and necessary disbursements in addition to any other relief to which that
party may be entitled; provided that, if Pledgor becomes liable for any such
fees, costs or other disbursements, such amounts will become Obligations under
the applicable Note secured by this Agreement.

         19.     Entire Agreement. This Agreement and the other documents and
instruments specifically referenced herein constitute the entire agreement
between the parties hereto with respect to the subject matter hereof and
thereof, and except as expressly set forth herein or therein, there are no
agreements or representations, written or oral, express or implied, with
respect to such subject matter. No provision of this Agreement may be modified,
waived or

                                     Page 7
<PAGE>   8
discharged unless such waiver, modification or discharge is agreed to in
writing signed by Pledgor and PSC. No waiver by either party hereto of any
condition or provision of this Agreement to be performed by the other party
will be deemed a waiver of any other provisions or conditions at the same or at
any prior or subsequent time.

         20.     Severability. If any provision of this Agreement is held to be
invalid or unenforceable for any reason, the validity and enforceability of all
other provisions of this Agreement will not be affected thereby.

         21.     Counterparts. This Agreement may be executed in any number of
multiple counterparts and by different parties on separate counterparts, all of
which when taken together will constitute one and the same agreement.

         22.     Assignment. Pledgor may not assign this Agreement or any
rights or obligations hereunder

         IN WITNESS WHEREOF, and intending to be legally bound, Pledgor and a
duly authorized representative of PSC have executed this Agreement as of the
date first above written.

                                PLEDGE AGREEMENT

         This Pledge Agreement (the "Agreement") is made as of February 14,
1997, by and between Perot Systems Corporation, a Delaware corporation ("PSC"),
and Terry M. Ashwill ("Pledgor").

         WHEREAS, PSC has granted Pledgor the option to purchase 20,000 shares
of PSC's Class A common stock pursuant to a Restricted Stock Agreement dated as
of February 14, 1997 (the "Restricted Stock Agreement");

         WHEREAS, PSC has extended credit to Pledgor and may extend additional
credit pursuant to the terms of a Promissory Note and a Bridge Note, each of
which is dated as of the date hereof and is in the amount of $37,500, for a
total of $75,000, to finance the acquisition of the Restricted Stock purchased
pursuant to the Restricted Stock Agreement (together the "Notes");

         NOW, THEREFORE, to secure the Obligations (as defined below), Pledgor
and PSC hereby agree as follows:

         1.      Definitions. Capitalized terms that are not otherwise defined
in this Agreement have the meanings assigned to such terms in the Restricted
Stock Agreement or the Notes, as appropriate.

         2.      Pledge of Securities. Pledgor hereby pledges and grants to PSC
a security interest in the following:

                 (a)      the Restricted Stock purchased by Pledgor pursuant to
         the Restricted Stock Agreement, together with any other shares of
         capital stock of PSC that may be distributed with respect to such
         Restricted Stock (collectively, the "Securities"), and all rights and
         privileges pertaining thereto;

                 (b)      all proceeds, products, cash, securities, dividends,
         increases, distributions and profits received from or on the
         Securities (the "Proceeds"), including without limitation
         distributions or payments in partial or complete liquidation or
         redemption, or as a result of reclassifications, readjustments,
         reorganizations or changes in the capital structure of the issuer of
         the Securities; and

                 (c)      all subscriptions, warrants, options, preemptive
         rights and other rights issued or otherwise granted by the issuer of
         the Securities or any other person on or in connection with the
         Securities or any other item of the Collateral (as defined below);

         (all of such property and rights described in items (a), (b) and (c)
         above are herein collectively called the "Collateral");





                                     Page 1
<PAGE>   2
TO HAVE AND TO HOLD the Collateral, together with all rights, titles,
interests, privileges and preferences appertaining to or incidental thereto,
unto PSC, and its respective successors and assigns, forever, subject, however,
to the terms, covenants and conditions hereinafter set forth. The security
interest granted and the assignments made hereunder are made as security only
and shall not subject PSC to, or transfer or in any way affect or modify, any
obligation of Pledgor with respect to any of the Collateral or any transaction
involving or giving rise thereto.

         3.      Obligations Secured. The pledge and security interest in the
Collateral granted hereby secures payment and performance of the following
obligations of Pledgor to PSC, whether now outstanding or incurred after the
date hereof (the "Obligations"): (a) all principal, interest, fees, expenses,
obligations and liabilities of Pledgor arising pursuant to or represented by
the Notes; (b) all taxes, assessments, insurance premiums, brokerage fees,
reasonable attorneys' fees and other expenses of sale of the Collateral; (c)
Pledgor's performance of his obligations under the Notes, this Agreement and
the Restricted Stock Agreement; and (d) all renewals, extensions and
modifications of the indebtedness and obligations referred to in the foregoing
clauses, or any part thereof.

         4.      Pledgor's Warranties and Indemnity. Pledgor represents,
warrants and covenants to PSC (a) that Pledgor is and will be the lawful owner
of the Securities, (b) that the Securities are and will remain free and clear
of all liens, encumbrances and security interests other than the security
interest granted by Pledgor hereunder, and (c) that Pledgor has the right and
authority to pledge the Securities and otherwise to comply with the provisions
hereof. If any adverse claim is asserted in respect of the Securities or any
portion thereof, except such as may result from an act of PSC not authorized
hereunder, Pledgor shall indemnify PSC and hold PSC harmless from and against
any losses, liabilities and expenses (including reasonable counsel fees)
incurred by PSC in exercising any right, power or remedy of PSC hereunder or
defending, protecting or enforcing the security interests created hereunder.
Any such loss, liability or expense so incurred shall be paid by Pledgor upon
demand, and shall become part of the Obligations of Pledgor secured pursuant to
this Agreement. Pledgor agrees to execute a stock power in blank for each
certificate evidencing any of the Securities and to deliver all such Securities
certificates with stock powers to PSC. PSC hereby consents to the pledge of the
Securities to PSC hereunder, notwithstanding any restrictions on transfer of
the Securities set forth in the Restricted Stock Agreement.

         5.      Negative Covenants. Pledgor covenants and agrees that, unless
PSC otherwise consents in writing Pledgor will not: (a) sell, assign or
transfer any rights of Pledgor in the Collateral; or (b) create any lien in, or
security interest in, or otherwise encumber, the Collateral, or any part
thereof, or permit the same to be or become subject to any lien, attachment,
execution, sequestration, other legal or equitable process, or any encumbrance
of any kind or character, except the security interest herein created in favor
of PSC.

         6.      Dividends and Other Distributions.

                 (a) Pledgor shall cause all non-cash dividends and
         distributions with respect to the Securities (including without
         limitation any stock dividends and any distributions made on or in
         respect of the Securities, whether resulting from a subdivision,





                                     Page 2
<PAGE>   3
         combination or reclassification of the Securities or received in
         exchange for or in respect of the Securities or any part thereof or as
         a result of any merger, consolidation, acquisition or other
         transaction) to be distributed directly to PSC, to be held by PSC as
         additional Collateral; and if any such distribution is made to
         Pledgor, he shall receive such distribution in trust for PSC and shall
         immediately transfer it to PSC.

                 (b)      So long as no Event of Default or Potential Default
         has occurred and is continuing, Pledgor shall be entitled to receive
         any cash dividends payable in respect of the Securities; provided
         that, upon receipt of any such cash dividend, Pledgor will promptly
         (and in any event within 30 days) pay to PSC in respect of the
         Obligations (to the extent of the Obligations then outstanding) the
         full amount of such cash dividend less any income taxes payable by
         Pledgor as a result of such cash dividend, and, pending such payment,
         such cash dividend will continue to constitute Collateral hereunder.

         7.      Voting Rights. So long as no Event of Default or Potential
Default has occurred and is continuing, Pledgor shall be entitled to exercise
any and all voting rights pertaining to the Securities for any purpose not
inconsistent with the terms of the Notes or this Agreement.

         8.      Termination of Rights. During any period when an Event of
Default has occurred and is continuing, all rights of Pledgor to receive
dividends pursuant to Section 6(b) or to exercise voting rights pursuant to
Section 7 shall cease and all such rights shall thereupon become vested in PSC,
which shall have the sole and exclusive right and authority to dispose of the
Securities and to receive dividends and exercise voting rights in respect of
the Securities.  Further, PSC shall have the right, during the continuance of
any Event of Default, to notify and direct the issuer of the Securities to make
all payments, distributions, dividends and any other distributions payable in
respect thereof directly to PSC. The issuer of the Securities making any
payment or distribution to PSC hereunder shall be fully protected in relying on
the written statement of PSC that it then holds a security interest that
entitles PSC to receive such payments and distributions. Any and all money and
other property paid over to or received by PSC pursuant to the provisions of
this Section 8 shall be retained by PSC as additional collateral hereunder and
may be applied in accordance with the provisions hereof.       

         9.      Rights and Remedies of PSC Upon and After Default.

                 (a)      Remedies. Upon the occurrence of an Event of Default,
         and in addition to any and all other rights and remedies which PSC may
         then have under this Agreement, the Restricted Stock Agreement, the
         laws of the United States or the Uniform Commercial Code, as then in
         effect in Texas (the "Code"), or otherwise, PSC may: (i) declare the
         entire unpaid balance of principal of and all accrued interest on the
         Obligations immediately due and payable, without notice (including
         notice of intention to accelerate and notice of acceleration) except
         as required under the Notes, demand or presentment, which are hereby
         waived; (ii) reduce its claim to judgment, foreclose or otherwise
         enforce its security interest in all or any part of the Obligations by
         any available judicial procedure; (iii) after notification, if any,
         expressly provided for herein, sell or otherwise dispose of, at the
         office of PSC, or elsewhere as chosen by PSC, all or





                                     Page 3
<PAGE>   4
         any part of the Collateral, and any such sale or other disposition may
         be as a unit or in parcels, by public or private proceedings, and by
         way of one or more contracts, (it being agreed that the sale of any
         part of the Collateral shall not exhaust the power of sale granted
         hereunder, but sales may be made from time to time until all of the
         Collateral has been sold or until the Obligations have been paid in
         full), and at any such sale it shall not be necessary to exhibit the
         Collateral; (iv) at PSC's discretion, retain the Collateral in
         satisfaction of the Obligations whenever the circumstances are such
         that PSC is entitled to do so under the Code; (v) apply by appropriate
         judicial proceedings for appointment of a receiver for the Collateral,
         or any part thereof, and Pledgor hereby consents to any such
         appointment; (vi) purchase the Collateral at any public sale; (vii)
         purchase the Collateral at any private sale if permitted by the Code;
         and/or (viii) exercise the rights set forth in Section 10 hereof.

                 (b)      Sale of Securities. Pledgor recognizes that PSC may
         be unable to effect a public sale of any or all of the Securities by
         reason of certain prohibitions contained in the federal securities
         laws and applicable state or foreign securities laws, and thus may
         resort to one or more private sales thereof to a restricted group of
         purchasers who will be obliged to agree, among other things, to
         acquire such securities for their own account for investment and not
         with a view to the distribution or resale thereof. Pledgor
         acknowledges and agrees that any such private sale may result in
         prices and other terms less favorable to the seller than if such sale
         were a public sale and, notwithstanding such circumstances, agrees
         that any such private sale shall be deemed to have been made in a
         commercially reasonable manner. PSC shall be under no obligation to
         delay a sale of any of the Securities for the period of time necessary
         to permit the issuer of such securities to register such securities
         for public sale under the federal securities laws, or under applicable
         state securities laws, even if such issuer would agree to do so. Upon
         the consummation of any private or public sale, PSC shall have the
         right to deliver, assign, and transfer to the purchaser thereof the
         Securities so sold. Each purchaser at any such sale shall hold the
         property sold absolutely free from any claim or right of whatsoever
         kind, and Pledgor hereby waives (to the extent permitted by law) all
         rights of redemption, stay and/or appraisal which it has or may at any
         time in the future have under any rule of law or statute now existing
         or hereafter enacted. PSC shall give Pledgor notice of PSC's intention
         to make any such public or private sale at broker's board or on a
         securities exchange to the extent required hereunder or by the Code.
         Such notice, in case of sale at broker's board or on a securities
         exchange, shall state the board or exchange at which such sale is to
         be made and the day on which the Securities, or that portion thereof
         so being sold, will first be offered for sale at such board or
         exchange. At any such sale the Securities may be sold in one lot as an
         entirety or in separate parcels, as PSC may determine. PSC shall not
         be obligated to make any such sale pursuant to any such notice if PSC
         shall determine not to do so, regardless of the fact that notice of
         sale of the Securities may have been given. PSC may without notice or
         publication, adjourn any public or private sale or cause the same to
         be adjourned from time to time by announcement at the time and place
         fixed for the sale, and such sale may be made at any time or place to
         which the same may be so adjourned. In case of any sale of all or any
         part of the Securities on credit or for future delivery, the
         Securities so sold may be





                                     Page 4
<PAGE>   5

         retained by PSC until the selling price is paid by the purchaser
         thereof, but PSC shall not incur any liability in case of the failure
         of such purchaser to take up and pay for the Securities so sold and,
         in case of any such failure, such Securities may again be sold upon
         like notice. PSC may also, at its discretion, proceed by a suit or
         suits at law, or in equity to foreclose its security interest and sell
         the Securities, or any portion thereof, under a judgment or decree of
         a court or courts of competent jurisdiction. If any consent, approval
         or authorization of any state, municipal or other governmental
         department, agency or authority should be necessary to effectuate any
         sale or other disposition of the Securities or any part thereof,
         Pledgor shall execute all such applications and other instruments as
         may be required in connection with securing any such consent, approval
         or authorization, and will otherwise use Pledgor's best efforts to
         secure the same.

                 (c)      Notification. Reasonable notification of the time and
         place of any public sale of the Collateral, or reasonable notification
         of the time after which any private sale or other intended disposition
         of the Collateral is to be made, shall be sent to Pledgor and to any
         other person entitled under the Code to notice; provided, that if the
         Collateral threatens to decline quickly in value, or if otherwise
         permitted by the Code, PSC may (but shall not be obligated to) sell or
         otherwise dispose of the Collateral without notification,
         advertisement or other notice of any kind. It is agreed that notice
         sent or given not less than ten calendar days prior to the taking of
         the action to which the notice relates is reasonable notification and
         notice for the purposes of this section.

                 (d)      Application of Proceeds. Upon the maturity of the
         Obligations or any part thereof, whether such maturity be by such
         terms of such instruments or through the exercise of any power of
         acceleration, PSC is authorized and empowered to apply any and all
         funds realized from the sale of the Collateral not previously credited
         against the Obligations first toward the payment of the costs, charges
         and expenses, if any, incurred in connection with the collection of
         such funds hereunder, and then toward the payment of the Obligations
         in such order as PSC, in its sole discretion, shall deem appropriate,
         and shall pay the balance remaining (if any) to Pledgor as prescribed
         by the Code or as a court of competent jurisdiction may direct.

         10.     Attorney-in-Fact. Pledgor hereby appoints PSC as the
attorney-in-fact for Pledgor for the purpose of carrying out the provisions of
this Agreement and taking any action and executing any instrument which PSC may
deem necessary or advisable to accomplish the purposes hereof, which
appointment is irrevocable and coupled with an interest.  Without limiting the
generality of the foregoing, PSC shall have the right and power to receive,
endorse and collect all checks and other orders for the payment of money made
payable to Pledgor and included within the Collateral and to give full
discharge for the same. Neither PSC nor any director or officer of the issuer
of the Securities shall have any liability for the distribution to and
collection of the Proceeds by PSC, but shall be fully protected in relying on
the written statement of PSC as to its authorization pursuant to this
paragraph. Any and all amounts collected by PSC pursuant hereto shall be
applied against the Obligations in the manner that PSC shall determine, in
PSC's sole and absolute discretion.

         11.     Certain Other Rights of PSC.

                 (a)      Duty of Care. PSC's only duty with respect to the
         Collateral shall be to exercise reasonable care to secure the safe
         custody thereof. PSC shall not have a duty to fix or preserve rights
         against prior parties to the Collateral, and shall never be liable for
         its failure to use diligence to collect any amount payable with
         respect to the Collateral, but shall be liable only to the account of
         Pledgor for what PSC may actually collect or receive thereon.

                 (b)      Financing Statement. PSC shall have the right at any
         time to execute and file this Agreement or a copy of this Agreement as
         a financing statement, but the failure of PSC to do so shall not
         impair the validity or enforceability of this Agreement.

                 (c)      Payment of Expenses. At PSC's option, PSC may
         discharge taxes, liens and interest, perform or cause to be performed,
         for and on behalf of Pledgor, any actions and conditions, obligations
         or covenants which Pledgor has failed or refused to perform and may
         pay for the repair, maintenance or preservation of any of the
         Collateral, and all sums so expended, including, but not limited to,
         attorneys' fees, court costs, agents' fee or commissions, or any other
         costs or expenses, shall bear interest from the date of payment at the
         highest legal rate and shall be deemed to constitute part of the
         Obligations secured by this Agreement.

         12.     Cumulative Rights and Remedies. All rights and remedies of PSC
hereunder are cumulative of each other and of every other right or remedy which
PSC may otherwise have at law or in equity or under any other contract or other
writing for the enforcement of the security interest herein or the collection
of the Obligations, and the exercise by PSC of one or more rights or remedies
shall not prejudice or impair the concurrent or subsequent exercise of other
rights or remedies. Should Pledgor have heretofore executed or hereafter
executed any other security agreement in favor of PSC in which a security
interest is created as security for the debts of another or others, in respect
of which Pledgor may not be personally liable, the security interest therein
created and all other rights, powers and privileges vested in PSC by the terms
thereof shall exist concurrently with the security interest created herein,
and, in addition, all property in which PSC holds a security interest under any
such other security agreement shall also be part of the Collateral hereunder,
and all or any part of the proceeds of the sale or other disposition of such
property may, in the discretion of PSC, be applied by PSC in accordance with
the terms hereof, and of such other security agreement, or agreements, or any
of them.

         13.     Termination. Upon payment in full by Pledgor of all
Obligations in accordance with their terms, this Agreement shall terminate and
PSC shall return to Pledgor all certificates evidencing the Securities (and
any related stock powers) then held under this Agreement.

         14.     Repurchase Option. If PSC exercises its right to cancel or
repurchase any of the Securities under the Restricted Stock Agreement, PSC
shall be entitled to release such Securities from the pledge under this
Agreement and cancel or repurchase such Securities in accordance with the terms
of the Restricted Stock Agreement.

         15.     Further Assurances. Pledgor agrees to execute and deliver such
further instruments and take such further actions as PSC may reasonably request
from time to time to preserve or give effect to its rights under this
Agreement.

         16.     Action by PSC. Any election, consent, waiver or other action
that may be taken by PSC hereunder will be taken by the Chairman of the Board,
unless Pledgor is then serving in such capacity, in which case such action will
be taken by the Board.

         17.     Notices. Any notice to PSC that is required or permitted by
this Agreement must be addressed to PSC at its principal office to the
attention of the President, with a copy to the General Counsel. Any notice to
Pledgor that is required or permitted by this Agreement must be addressed to
Pledgor at the most recent address for Pledgor reflected in the appropriate
records of PSC. Either party may at any time change its address for
notification purposes by giving the other prior written notice of the new
address and the date upon which it will become effective. Whenever this
Agreement requires or permits any notice from one party to another, the notice
must be in writing and must be sent by courier, overnight delivery service,
facsimile or certified mail, return receipt requested, and such notice will be
deemed to be given (a) if sent by courier, on the date actually delivered, (b)
if sent by overnight delivery service, one day after being sent, (c) if sent by
telecopy, on the date that confirmation of transmission is received by the
sender, or (d) if sent by certified mail, on the third business day after being
mailed.

         18.     Enforcement. This Agreement will be governed by and construed
in accordance with the laws of the State of Texas, without regard to the choice
of law rules thereof. PSC will be entitled, in addition to any other remedies
it may have at law or in equity, to temporary and permanent injunctive and
other equitable relief to enforce the provisions of this Agreement. Any action
to enforce the provisions of, or otherwise relating to, this Agreement may be
brought in the appropriate courts in Dallas, Dallas County, Texas, and Pledgor
hereby consents to the personal jurisdiction of such courts in any such action;
provided that, at the request of PSC or Pledgor, any claim or dispute arising
out of or relating to this Agreement or Pledgor's employment by PSC or the
termination of such employment, including any federal or state statutory
claims, will be resolved without resort to the courts solely through mediation
and, if mediation is not successful, through binding arbitration pursuant to
the rules of the American Arbitration Association. Neither party will be liable
to the other for punitive damages for any such claim or dispute. If any action
at law or in equity is necessary to enforce or interpret the terms of this
Agreement, the prevailing party will be entitled to reasonable attorneys' fees,
costs and necessary disbursements in addition to any other relief to which that
party may be entitled; provided that, if Pledgor becomes liable for any such
fees, costs or other disbursements, such amounts will become Obligations under
the applicable Note secured by this Agreement.

         19.     Entire Agreement. This Agreement and the other documents and
instruments specifically referenced herein constitute the entire agreement
between the parties hereto with respect to the subject matter hereof and
thereof, and except as expressly set forth herein or therein, there are no
agreements or representations, written or oral, express or implied, with
respect to such subject matter. No provision of this Agreement may be modified,
waived or





                                     Page 7
<PAGE>   8
discharged unless such waiver, modification or discharge is agreed to in
writing signed by Pledgor and PSC. No waiver by either party hereto of any
condition or provision of this Agreement to be performed by the other party
will be deemed a waiver of any other provisions or conditions at the same or at
any prior or subsequent time.

         20.     Severability. If any provision of this Agreement is held to be
invalid or unenforceable for any reason, the validity and enforceability of all
other provisions of this Agreement will not be affected thereby.

         21.     Counterparts. This Agreement may be executed in any number of
multiple counterparts and by different parties on separate counterparts, all of
which when taken together will constitute one and the same agreement.

         22.     Assignment. Pledgor may not assign this Agreement or any
rights or obligations hereunder.

         IN WITNESS WHEREOF, and intending to be legally bound, Pledgor and a
duly-authorized representative of PSC have executed this Agreement as of the
date first above written.

                             STOCK OPTION AGREEMENT

THIS AGREEMENT, dated as of December 12, 1997, is by and between Perot Systems
Corporation ("Perot Systems"), a Delaware corporation, and Terry M. Ashwill
("Participant").

                                  WITNESSETH:

WHEREAS, Perot Systems has adopted the Perot Systems Corporation 1991 Stock
Option Plan (the "Plan") to enable employees of Perot Systems and its
majority-owned subsidiaries to acquire shares of Class A common stock, $0.01
par value, of Perot Systems ("Common Stock") in accordance with the provisions
of the Plan; and

WHEREAS, the Committee of the Board of Directors of Perot Systems appointed to
administer the Plan (the "Committee") has selected Participant to participate
in the Plan and has determined to grant Participant the right and option to
purchase shares of Common Stock in accordance with the terms and conditions of
this Agreement, provided, that if any change is made in the shares of Common
Stock (including, but not limited to, by stock dividend, stock split, or merger
or consolidation, but not including the issuance of additional shares for
consideration), the Board of Directors or the Committee, will make such
adjustments in the number and kind of shares (which may consist of shares of a
surviving corporation to a merger) that may thereafter be optioned and sold
under the Plan and the number and kind of shares (which may consist of shares of
a surviving corporation to a merger) and purchase price per share of shares
subject to outstanding Stock Option Agreements under the Plan as the Board of
Directors or the Committee determines are equitable to preserve the respective
rights of the Participants under the Plan.

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises
and other terms and conditions set forth in this Agreement, Perot Systems and
Participant agree as follows:

1.       Certain Definitions. As used in this Agreement, the following terms
         have the meanings indicated:

         (a)     "Company" means Perot Systems and its majority-owned
                 subsidiaries.

         (b)     "Confidential Information" means all written,
                 machine-reproducible, oral and visual data, information and
                 material, including but not limited to business, financial
                 and technical information, computer programs, documents and
                 records (including those that Participant develops in the scope
                 of his or her employment) that (i) the Company or any of its
                 customers or suppliers treats as proprietary or confidential
                 through markings or otherwise, (ii) relates to the Company or
                 any of its customers or suppliers or any of their business
                 activities, products or services (including software programs
                 and techniques) and is competitively sensitive or not
                 generally known in the relevant trade or industry, or (iii)
                 derives independent economic value from not

<PAGE>   5
                 being generally known to, and is not readily ascertainable by
                 proper means by, other persons who can obtain economic value
                 from its disclosure or use. Confidential Information does not
                 include any information or material that is approved by Perot
                 Systems for unrestricted public disclosure.

         (c)     "Expiration Date" means the date and time as of which the
                 Option expires, which is the earlier of (i) the close of
                 business on the date one year after the entire Option has
                 Vested or (ii) the date and time as of which all rights to
                 exercise the Option are terminated under Section 2(d).

         (d)     "Market Value" of a share of Purchased Stock on a given date
                 means (i) if the Purchased Stock is Publicly Traded, the
                 closing sale price for Purchased Stock, as determined in good
                 faith by the Board of Directors, on such date or, if no
                 closing sale price is available for such date, on the most
                 recent prior date for which a closing sale price is available
                 or, if no closing sale price is available, the closing bid
                 price, as so determined, on such date or, if no closing bid
                 price is available for such date, the closing bid price on the
                 most recent prior date for which a closing bid price is
                 available, or (ii) if the Purchased Stock is not Publicly
                 Traded, its fair market value, as determined in good faith by
                 the Board of Directors, as of the most recent Valuation Date
                 on or before such date.

         (e)     "Net Investment Proceeds," with respect to any share of
                 Purchased Stock sold or otherwise transferred by Participant
                 or Participant's successor in interest, means the greater of
                 the value of the gross proceeds received for such share or the
                 Market Value of such share on the date of sale or transfer
                 less, in either case, (i) the exercise price of the Option for

2.       Grant of Option; Purchase of Stock.

         (a)     Subject to the terms, conditions, and restrictions set forth
                 in the Plan and in this Agreement, Perot Systems hereby grants
                 to Participant, and Participant hereby accepts from Perot
                 Systems, the option to purchase from Perot Systems the number
                 of shares of Common Stock specified on Attachment A hereto, at
                 the purchase price so specified, which option will Vest in
                 Participant in accordance with the Vesting Schedule set forth
                 on Attachment A hereto. The Option shall only continue to Vest
                 only for as long as Participant is an employee of Company,
                 unless the Committee, in its sole discretion, agrees in
                 writing otherwise. Participant will have the right to exercise
                 the Vested Option and purchase Common Stock after the Option
                 Vests as provided in Section 2(d) below.

         (b)     The purchase price of shares as to which the Option is
                 exercised must be paid to Perot Systems at the time of the
                 exercise either in cash or in such other consideration as the
                 Committee may approve having a total fair market value, as
                 determined by the Committee, equal to the purchase price, or a
                 combination of cash and such other consideration.

         (c)     The Committee may elect to assist Participant in satisfying an
                 obligation to pay or withhold taxes required as a result
                 of the exercise of this Option by accepting shares of Purchased
                 Stock at Market Value to satisfy the tax obligation. The shares
                 of Purchased Stock accepted may be either shares withheld upon
                 the exercise of this Option or other shares already owned by
                 Participant. In determining whether to approve acceptance of
                 Purchased Stock to satisfy such a tax obligation, the Committee
                 may consider whether the shares proposed to be delivered are
                 subject to any holding period or other restrictions on transfer
                 and may waive or arrange for the waiver of any such
                 restrictions.

                                       3
<PAGE>   7
         (d)     The Option is only exercisable as to Vested Options. Once
                 Vested, the Option may be exercised until the Expiration Date,
                 provided, however, (i) if the Participant ceases to be an
                 employee for any reason other than death, the Option may be
                 exercised only for sixty days after the date of cessation of
                 employment, and in any case no later than the Expiration Date,
                 and (ii) if the Participant ceases to be an Employee because of
                 death of the Participant, the Option may be exercised by the
                 Participant's estate only for two years after the Participant's
                 Death and in any case no later than the Expiration Date.

3.       Restrictions on Transfer. The following restrictions on transfer apply
         unless the Committee otherwise agrees in writing or unless the
         transfer is by will or the laws of descent and distribution upon
         Participant's death:

         (a)     The Option may not be sold or otherwise transferred and is
                 exercisable only by Participant during Participant's lifetime.

         (b)     One-half of the shares of Purchased Stock purchased on any day
                 may not be sold or otherwise transferred for two years after
                 purchase.

         (c)     Shares of Purchased Stock may not be sold or otherwise
                 transferred unless the holder has given Perot Systems any
                 notice required under Section 4(a) and Perot Systems has
                 waived in writing any right it has to buy back the shares
                 under Section 4(a).

         (d)     Shares of Purchased Stock may not be sold or otherwise
                 transferred without the written consent of the underwriters of
                 the initial underwritten public offering of Common Stock
                 registered under the Securities Act, for the longer of (i) six
                 months after the Common Stock is listed on a registered
                 national securities exchange or approved for quotation in the
                 NASDAQ system and (ii) for the same period, and under the same
                 conditions, as the underwriters request from the top five
                 executive officers of Perot Systems (as designated by the
                 Chief Executive Officer of Perot Systems) as a group.

         Perot Systems is not obligated to recognize any purported sale or
         other transfer of the Option or any Purchased Stock in violation of
         this Section 3 and, unless it elects to do otherwise, may treat any
         such purported sale or transfer as null, void, and of no effect.

4.       Rights to Buy Back Purchased Stock and to Require Payback of Certain
         Profits.

         (a)     At any time before the Purchased Stock is Publicly Traded, if
                 Participant or any subsequent holder of shares of Purchased
                 Stock desires or is obligated to sell or otherwise transfer
                 any such shares (including any distribution to heirs or other
                 beneficiaries of Participant's estate), the holder is required
                 to give Perot Systems written notice of the proposed sale or
                 transfer, including notice of the proposed purchaser or
                 transferee, and, for a period of 30 days after receipt of
                 such notice, Perot Systems will have the right to buy back
                 such shares for cash at a purchase price equal to the price
                 per share paid by Participant for the shares plus simple
                 interest on


                                      4
<PAGE>   8
                 such amount at the rate of 8% per annum from the date of
                 payment by Participant to the date of tender of payment by
                 Perot Systems is set forth in Section 4(c) below.

         (b)     If the Committee discovers that Participant has engaged in any
                 conduct prohibited by Section 5 or if Participant ceases to be
                 employed by the Company and the Committee, in its sole
                 discretion, determines that Participant's cessation of
                 employment resulted from a Termination for Substantial
                 Misconduct or would have resulted in a Termination for
                 Substantial Misconduct had the relevant facts been known at
                 the time of Participant's cessation of employment, Perot
                 Systems will have the right for 150 days after the Committee
                 discovers the relevant facts to cancel any unexercised Option,
                 whether or not Vested, and to buy back from Participant any
                 shares of Purchased Stock then owned by Participant, at a
                 purchase price equal to the price per share paid by
                 Participant for the shares plus simple interest on such amount
                 at the rate of 8% per annum from the date of payment by
                 Participant to the date of tender of payment by Perot Systems
                 as set forth in Section 4(c) below, and the right to require
                 Participant to pay back to Perot Systems in cash the Net
                 Investment Proceeds with respect to any shares of Purchased
                 Stock that have been sold or otherwise transferred by
                 Participant.

         (c)     Whenever Perot Systems has a right to buy back shares of
                 Purchased Stock or to require Participant to pay back to Perot
                 Systems Participant's Net Investment Proceeds with respect to
                 any shares of Purchased Stock under this Section 4, Perot
                 Systems may exercise its right by notifying Participant or the
                 subsequent holder of Perot Systems' election to exercise its
                 right within the designated exercise period. In the case of a
                 buyback under Section 4(a) or Section 4(b), the giving of
                 such notice will give rise to an obligation on the part of
                 Participant or the subsequent holder to tender to Perot
                 Systems, within 10 days, any previously issued certificate
                 representing shares of Purchased Stock to be bought back, duly
                 endorsed in blank or having a duly executed stock power
                 attached in proper form for transfer. If any such certificate
                 is not tendered within 10 days, Perot Systems may cancel any
                 outstanding certificate representing shares to be bought back.
                 Perot Systems is required to tender the purchase price for
                 shares to be bought back under this Section 4 within 20 days
                 of giving notice of its election to exercise its right to buy
                 back shares. If the person from whom the shares are to be
                 bought back has not complied with an obligation to return a
                 certificate representing shares to be bought back, however,
                 Perot Systems is not required to tender the purchase price
                 until 20 days after the certificate is returned or 20 days
                 after it cancels the certificate, whichever occurs first.

5.       Competition and Non-Disclosure. Participant acknowledges that: (i) in
         the course and as a result of employment with the Company, Participant
         will obtain special training and knowledge and will come in contact
         with the Company's current and potential customers, which training,
         knowledge, and contacts would provide invaluable benefits to
         competitors of the Company; (ii) the Company is continuously
         developing or receiving Confidential Information, and that during
         Participant's employment he or she will receive Confidential
         Information from the Company, its customers and suppliers and special
         training related to the Company's business methodologies; and (iii)
         Participant's employment by Company



                                       5
<PAGE>   9
         creates a relationship of trust that extends to all Confidential
         Information that becomes known to Participant.  Accordingly, and in
         consideration of Perot Systems' granting this Option to Participant,
         Participant agrees that Perot Systems will be entitled to terminate
         all rights to exercise the Option and to exercise the rights specified
         in Section 4 above if Participant does any of the following without
         the prior written consent of the Company:

         (a)     while employed by the Company or within one year thereafter:

                 (i)      competes with, or engages in any business that is
                          competitive with, the Company within 250 miles of any
                          location at which Participant was employed by or
                          provided services to the Company;

                 (ii)     solicits or performs services, as an employee,
                          independent contractor, or otherwise, for any person
                          (including any affiliates or subsidiaries of that
                          person) that is or was a customer or prospect of the
                          Company during the two years before Participant's
                          employment with the Company ended if Participant
                          solicited business from or performed services for
                          that customer or prospect while employed by Company
                          or

                 (iii)    recruits, hires, or helps anyone to recruit or hire
                          anyone who was an employee of Perot Systems, or of
                          any of its customers for whom Participant performed
                          services of from whom Participant solicited business,
                          within the six months before Participant's employment
                          with the Company ended; or

         (b)     discloses or uses any Confidential Information, except in
                 connection with the good faith performance of Participant's
                 duties as an employee; or fails to take reasonable precautions
                 against the unauthorized disclosure or use of Confidential
                 Information; or fails, upon Perot Systems' request, to execute
                 and comply with a third party's agreement to protect its
                 confidential and proprietary information, or solicits or
                 induces the unauthorized disclosure or use of Confidential
                 Information.

         If any court of competent jurisdiction finds any provision of this
         Section 5 to be unreasonable, then that provision shall be considered
         to be amended to provide the broadest scope of protection to the
         Company that such court would find reasonable and enforceable.

6.       Compliance with Securities Laws, Participant hereby agrees that upon
         demand by Perot Systems, any person exercising this Option, at the
         time of such exercise, will deliver to Perot Systems a written
         representation to the effect that the shares of Purchased Stock being
         acquired are being acquired for investment and not with a view to any
         resale or distribution thereof. Participant further agrees that neither
         Participant nor any successor in interest of Participant will sell or
         otherwise transfer the Option or any shares of Purchased Stock in any
         way that might result in a violation of any federal or state
         securities laws or regulations.  Participant further acknowledges and
         agrees that Perot Systems may require Participant or any subsequent
         holder of the Option or of any shares of Purchased Stock to provide
         Perot Systems, prior to any sale or other transfer, with such other
         representations, commitments,


                                       6
<PAGE>   10
         and opinions regarding compliance with applicable securities laws and
         regulations as Perot Systems may deem necessary or advisable.

7.       Stock Certificates: Rights as Shareholder. Perot Systems will retain
         for safekeeping all certificates representing shares of Purchased
         Stock. Each such certificate will bear such legends as the Committee
         determines are necessary or appropriate. Whether or not certificates
         representing shares of Purchased Stock have been issued or delivered,
         Participant will have all the rights of a shareholder of Purchased
         Stock, including voting, dividend and distribution rights, with
         respect to shares of Purchased Stock owned by Participant. Participant
         will not have any rights as a shareholder with respect to any shares
         of Purchased Stock subject to the Option before the date of issuance
         to Participant of shares upon exercise of the Option.

8.       Income Tax Withholding. Participant shall, upon request by the
         Company, reimburse the Company for, or the Company may withhold from
         sums or property otherwise due or payable to Participant, any amounts
         the Company is required to remit to applicable taxing authorities as
         income tax withholding with respect to the Option or any Purchased
         Stock. If shares of Purchased Stock are withheld for such purpose,
         they will be withheld at Market Value. If Participant fails to
         reimburse the Company for any such amount when requested, the Company
         has the right to recover that amount by selling or canceling
         sufficient shares of any Purchased Stock held by Participant.

9.       Compliance with Plan. Participant acknowledges receipt of a copy of
         the Plan and further acknowledges that this Agreement is entered into,
         and the Option is granted, pursuant to the Plan. If the provisions of
         the Plan are inconsistent with the provisions of this Agreement, the
         provisions of the Plan supersede the provisions of this Agreement.

10.      Notices. Any notice to Perot Systems or the Company that is required
         or permitted by this Agreement shall be addressed to the attention of
         the Secretary of Perot Systems at its principal office. Any notice to
         Participant that is required or permitted by this Agreement shall be
         addressed to Participant at the most recent address for Participant
         reflected in the appropriate records of the Company. Either party may
         at any time change its address for notification purposes by giving
         the other written notice of the new address and the date upon which it
         will become effective. Whenever this Agreement requires or permits any
         notice from one party to another, the notice must be in writing to be
         effective and, if mailed, shall be deemed to have been given on the
         third business day after the same is enclosed in an envelope,
         addressed to the party to be notified at the appropriate address,
         properly stamped, sealed, and deposited in the United States mail,
         and, if mailed to the Company, by certified mail, return receipt
         requested.

11.      Remedies. Perot Systems is entitled, in addition to any other
         remedies it may have at law or in equity, to temporary and permanent
         injunctive and otherwise equitable relief to enforce the provisions of
         this Agreement. Any action to enforce the provisions of, or other
         relating to, this Agreement may be brought in the state or federal
         courts having jurisdiction in Dallas, Dallas County, Texas. By signing
         this Agreement, Participant consents to the personal jurisdiction of
         such courts in any such action.

12.      Assignment. This Agreement shall inure to the benefit of and be
         binding upon the parties hereto and their respective heirs, personal
         representatives, successors, and assigns. However, Participant does
         not have the power or right to assign this Agreement without the prior

                     [PEROT SYSTEMS CORPORATION LETTERHEAD]

January 4, 1997
Mr. Terry Ashwill
255 15 North Forest Road
Unit 16
Rio Verde, AZ 85263

Dear Terry:

It is my sincere pleasure to extend an offer of employment to you for the
position of Chief Financial Officer, effective as soon as practicable in
January 1997. This offer of employment includes a base salary of $29,167.00 per
month. You will also be eligible for an annual incentive bonus as an executive,
payable in February, 1998. Your target plan bonus for 1997 is 25% of base pay,
subject to adjustment up or down based on company and individual performance.

In addition, in light of your potential to contribute to the long-term success
of Perot Systems Corporation, upon signing an Associate Agreement you will be
granted 300,000 stock options to purchase shares of Perot Systems stock,
vesting annually over ten years and 50,000 stock options vesting annually over
5 years. Details outlining the Perot Systems Stock Option Plan and your stock
option agreement, which govern the terms and conditions of the grant, will be
distributed under separate cover. If you wish, you may instead purchase
restricted stock instead of receiving options, provided that you purchase the
shares in January 1997.

<PAGE>   2

Mr. Terry Ashwill
January 4, 1997

We will also offer to you a special termination provision if you leave Perot
Systems for certain reasons during your first 2 years with us. This will apply
(a "Triggering Event") if during this two year period (a) you terminate your
employment with Perot Systems and you neither (I) within twelve months from the
termination, work for a competitor of Perot Systems, or (II) within six months
from the termination, work for a company with which you had discussions or
communications (directly or through third parties) concerning or relating to
employment while you were employed at Perot Systems or (b) you are terminated
by Perot Systems other than for Cause. Cause means termination of employment
for a felony conviction, actions involving moral turpitude, theft, or
dishonesty in a material matter; or material breach of your obligations to
maintain information on a confidential basis.

The protection you will receive is as follows: If a Triggering Event occurs
during the first two years of your employment with Perot Systems, so many
shares or options up to 50,000 shares/options of Perot Systems stock (the
"Triggering Event Shares") will vest under the option or restricted stock
agreements mentioned above, regardless of whether such shares would otherwise
have vested under the normal ten year and five year prorata vesting schedules
under those agreements, if such shares are required so that, on the Measurement
Date, the Value of the Triggering Event Shares is $1,500,000. The Measurement
Date will be the third anniversary of your effective date of employment with
Perot Systems. The Value will be (a) if Perot Systems shares are listed on a
registered national securities exchange or approved for quotation on the

<PAGE>   3
Mr. Terry Ashwill

Page 3

National Association of Securities Dealers Automated Quotation ("NASDAQ")
system, the closing sale price of such shares on such date, as determined in
good faith by Perot Systems, or if no closing sale price is available for such
date, on the most recent prior date for which a closing sale price is available
or, if no closing sale price is available, the closing bid price, as so
determined, on such date, or, if no closing bid price is available for such
date, the closing bid price on the most recent prior date for which a closing
bid price is available, or (ii) if the shares are not so publicly traded, the
fair market value, as determined in good faith by the Board of Directors, as of
the most recent Perot Systems appraisal, provided that such appraisal will not
discount the value of the stock because it is not publicly traded.

The protection above is in addition to, and does not otherwise affect, the
normal ten year and five year prorata vesting provided by the stock/option
agreements. As an example, if a Triggering Event occurs prior to your first
year anniversary with Perot Systems, you will not have vested any
shares/options and the maximum amount of "protection" shares/options available
to you will be 50,000. If a Triggering Event occurs between your first
anniversary and your second anniversary with Perot Systems, and you will
otherwise have vested 40,000 shares/options under the normal ten year and five
year prorata provisions of the contract, the maximum amount of "protection"
shares/options available to you will be 10,000. In the event that such 40,000
shares/options vested during that year but are repurchased due to violation of
the standard provisions of those agreements but which otherwise does not
violate this letter, then the maximum number of "protection" shares/options
available to you will be 50,000.

The company sponsored benefits plan includes medical, vision and dental
benefits, life insurance, short term and long term disability insurance, 401(k) 
plan, tuition reimbursement, and Flexible Spending Accounts.

In addition to the above, during your first year with Perot Systems, Perot
Systems will reimburse you for up to $4,000 (on an after tax basis) in personal
finance expertise assistance.

In connection with your relocation to Dallas, Perot Systems agrees to purchase
your current personal residence at terms consistent with the Perot Systems
executive relocation program. This will include transportation of your personal
household items to Dallas, up to 90 days storage for those items, and insurance
during this move and storage. Perot Systems will also reimburse you for
temporary living expenses in Dallas during this ninety day period.

Perot Systems will not require you to relocate from Dallas.

This offer is for employment at will, which means that either you or Perot
Systems can terminate the employment at any time, with or without cause, and is
contingent upon execution of an Associate Agreement.

in any Perot Systems stock or option plans or agreements or other related
documents, with respect to matters specifically addressed in this offer letter.

Dr. George H. Heilmeier 
Chairman and CEO 
Bellcore 
445 South Street 
Morristown, NJ 07960


Dear George:

Perot Systems Corporation ("Perot Systems") is pleased to engage you as a
consultant for approximately 20% of your time, in addition to the time that you
will devote as a Board member. As a consultant, you will work on the development
and implementation of the company's business and technology strategies and on
the structure of major business relationships, as well as other projects. We
will work with you to coordinate the timing of your services consistent with
your other business commitments.

We will pay you $12,500 per month for your consulting services and reimburse you
for your reasonable, allocated travel expenses, consistent with Perot Systems'
policies. In addition, we will grant you options to buy 20,000 shares of Perot
Systems common stock at an exercise price of $6.75 per share, with 4,000 of the
options vesting on each of the first five anniversaries of the date of this
letter for as long as this agreement remains in effect, in accordance with the
enclosed Stock Option Agreement and Plan.

You are furnishing services to Perot Systems as an independent contractor. This
letter agreement is not intended to create an employer-employee or agent
relationship between Perot Systems and you. Perot Systems is not responsible for
withholding any amounts for your income tax, Social Security or any other taxes.

If you inform Perot Systems in writing that any consulting services Perot
Systems asks you to perform would conflict with Section 5 of your retirement
agreement as attached to your letter to me dated September 22, 1997, Perot
Systems will immediately withdraw its request.

The term of this agreement will be from November 17, 1997, to November 16, 2002,
provided that either party may terminate this agreement prior to November 16,
2002, at the terminating parties sole discretion, and for any or no reason, on
one month's notice. Upon termination of this agreement you will cease to receive
compensation and the vesting of your options shall cease.




<PAGE>   2


This agreement incorporates by reference the terms of Attachment A
("Confidentiality and Proprietary Rights Agreement") and constitutes the final,
entire, and exclusive agreement between Perot Systems and you with respect to
your consulting for Perot Systems and may only be amended in a writing signed by
both parties.

If you agree to the terms of this agreement, please sign both copies of this
letter and both copies of Attachment A, keep one copy of each for your records,
and return the other copies to Patti Karn, our Stock Administrator, in the
enclosed return envelope. Please also sign the enclosed Stock Option Agreement,
return it to Patti, and she will return a signed copy to you.

Separately you have received and executed a Stock Option Agreement for 30,000
shares vesting over five years as compensation for your service on the Board of
Directors, and the Plan governing that Option Agreement.

We are very excited about the prospect of working with you.

Very truly yours,


/s/ PETER ALTABEF

     (e)  information and materials provided to Perot Systems by its customers,
          alliance partners, and vendors.

2.   Consultant shall use his best efforts to keep Perot Systems' Confidential
     Information secret. 

3.   Consultant has no obligation with respect to any Confidential Information
     which Consultant can establish (a) he independently developed; (b) is or
     becomes publicly known without a breach of this Agreement by Consultant;

     maintain its confidentiality; or (d) is approved for release by Perot
     Systems in writing.

4.   Consultant shall and hereby does assign to Perot Systems all of his rights,
     title, and interest in any Confidential Information that he develops or
     helps to develop while working for Perot Systems as an independent
     contractor or employee and shall promptly and fully inform Perot Systems in
     writing of any such Confidential Information. Consultant shall provide, at

5.   Consultant shall not disclose Confidential Information to any agent or
     other non-party without the prior written consent of Perot Systems.

6.   Consultant shall not use Confidential Information for competing with Perot
     Systems or for any purpose not in furtherance of the business relationship
     between them.

7.   Upon the termination of the consulting agreement or at Perot Systems'

     Confidential Information in any form and shall destroy all notes or
     memoranda in any form that are based wholly or partly on Confidential
     Information.

     any other legal or equitable remedies.

10.  This Agreement is governed by the laws of Texas without regard to its rules
     on conflicts of law, and Consultant consents to the exclusive personal
     jurisdiction of the state and federal courts in Texas. Consultant may not
     assign his rights or obligations under this Agreement. No modification or
     waiver of any provision of this Agreement shall be effective unless in
     writing and signed by the party sought to be bound. This Agreement shall
     expire two years after the termination of the consulting agreement to which

                  STOCK OPTION/RESTRICTED STOCK INCENTIVE PLAN

                             STOCK OPTION AGREEMENT

THIS AGREEMENT, dated as of, November 17,1997, is by and between Perot Systems
Corporation, a Delaware corporation ("Perot Systems" or the "Company"), and
George H. Heilmeier ("Participant").

                                   WITNESSETH

WHEREAS, Perot Systems has adopted the Perot Systems Corporation 1996 Advisor
and Consultant Stock Option/ Restricted Stock Incentive Plan (the "Plan") to
enable nonemployee advisors of the Company, and consultants under contract with
the Company, to acquire shares of Class A Common Stock, $0.01 par value, of the
Company ("Common Stock") in accordance with the provisions of the Plan; and

WHEREAS, the Committee of the Board of Directors of Perot Systems with
responsibility for administering this Plan (the "Committee") has selected
Participant to participate in the Plan and has determined to grant Participant
the option to purchase shares of Common Stock in accordance with the terms and
conditions of this Agreement, provided, that if any change is made in the shares
of Common Stock (including, but not limited to, by stock dividend, stock split,
or merger or consolidation, but not including the issuance of additional shares
for consideration), the Board of Directors or the Committee will make such
adjustments in the number and kind of shares (which may consist of shares of a
surviving corporation to a merger) and purchase price per share of shares
subject to outstanding options issued under the Plan as the Board of Directors
or the Committee determines are equitable to preserve the respective rights of
the Participants under the Plan;

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises and
other terms and conditions set forth in this Agreement, Perot Systems and
Participant agree as follows:

1.   Award.

     (a) Subject to the terms, conditions, and restrictions set forth in the
     Plan and in this Agreement, Perot Systems hereby awards and grants to
     Participant, and Participant hereby accepts from Perot Systems, the option
     to purchase from Perot Systems the number of shares of Common Stock, at the
     purchase price, and in accordance with the schedule specified on Attachment
     A hereto.


                                     - 1 -
<PAGE>   6

     (b) The option may be exercised only with respect to vested options. Once
     vested, the options may be exercised until the expiration date set forth on
     Exhibit A hereto (unless such right to exercise is earlier terminated
     pursuant to Section 3 hereunder), by delivering written notice of the
     exercise to Perot Systems specifying the number of shares to be purchased
     and paying in full the purchase price for such shares either

         (i) in cash or check in United States dollars or

         (ii) by tendering to Perot Systems shares of the same class as the
         shares being acquired that have been owned by the person exercising the
         option for any period necessary to avoid a charge to Perot Systems'
         earnings and having a fair market value on the date of exercise equal
         to such purchase price, or

         (iii) by a combination of such cash and shares.

     (c) For purposes of this Agreement, the term "fair market value" means,
     with respect to any Purchased Stock means,

(i) if the Purchased Stock is publicly traded, the closing sale price on the
date of determination in the market in which the shares are principally traded
(which may be a stock exchange) or, if no such closing sale price is available
for such date, on the most recent previous date for which such a closing sale
price is available or, if no closing sale price is available, the closing bid
price on such date as quoted in the National Association of Securities Dealers
Automated Quotation ("NASDAQ") system, or by the National Quotation Bureau,
Inc., if not so quoted, or, if no such closing bid price is available for such
date, the closing bid price on the most recent previous date for which such a
closing bid price is available, or

(ii) if Purchased Stock is not publicly traded, their fair market value,
determined by reference to the most recent appraisal of the Common Stock
conducted by appraisers selected by the Board of Directors of Perot Systems.

     (d) For purposes of this Agreement, the term "publicly traded" means
     Purchased Stock has been listed on a registered national securities
     exchange or approved for quotation in the NASDAQ system.

     (e) For purposes of this Agreement, the term "Purchased Stock" means any
     Common Stock or other security purchased upon the exercise of this option,
     together with any successor security, property or cash issued or
     distributed by Perot Systems or any successor entity, whether by way of
     merger, consolidation, share exchange, reorganization, liquidation,
     recapitalization, or otherwise.

2.   Restrictions on Transfer of Option and Purchased Stock.

     (a) The option evidenced by this Agreement may not be sold or otherwise
     transferred, and is exercisable only by Participant.

     (b) Shares of Purchased Stock may not be sold or otherwise transferred for
     six months after stock of the same class as the Purchased Stock is publicly
     traded.

     (c) Perot Systems is not obligated to recognize any purported sale or other
     transfer of the option or Purchased Stock in violation of this Section 2
     and may treat any such purported sale or transfer as null, void, and of no
     effect.

3.   Cessation of Service to Perot Systems.

     Any invested options evidenced by this Agreement will terminate and, except
     to the extent set forth in this Section 3, will cease being exercisable if
     Participant, for any reason whatsoever, is no longer serving Perot Systems
     in at least one of the following capacities: a consultant under contract to
     Perot Systems, or full time employee of Perot Systems (a "Termination
     Event"), unless the Committee, in its sole discretion, agrees in writing
     otherwise. If a Termination Event occurs by reason other than the death of
     Participant, Participant will have sixty days after the Termination Event
     to exercise all vested options hereunder, but in no event later than the
     expiration date set forth on Attachment A hereto. If a Termination Event
     occurs by reason of the death of Participant, Participant's estate will
     have two years after the Termination Event to exercise all vested options
     hereunder, but in no event later than the expiration date set forth on
     Attachment A hereto.

4.   Company's Right of First Refusal.

     (a) Unless and until shares of Purchased Stock are publicly traded, Perot
     Systems will have a right of first refusal to purchase such shares
     purchased hereunder if the holder of the shares desires or is obligated to
     sell or otherwise transfer the shares, but this right will not apply to a
     transfer upon Participant's death by will or by the laws of descent and
     distribution.

     (b) Any holder of such shares who desires or is obligated to sell or
     otherwise transfer them before shares of Purchased Stock are publicly
     traded must give Perot Systems written notice of the proposed sale or other
     transfer. The notice must include the name of the proposed purchaser or
     transferee and describe the circumstances of the transfer. Perot Systems
     may purchase any or all of the shares proposed to be sold or transferred by
     notifying the holder within 30 days of its



                                     - 3 -
<PAGE>   8

     receipt of the notice of its election to exercise its right of first
     refusal and tendering the purchase price of the shares as soon as
     reasonably practicable thereafter.

     (c) The purchase price at which Perot Systems will purchase shares under
     its right of first refusal will be their fair market value, determined by
     reference to the most recent appraisal of the Common Stock conducted by
     appraisers selected by the Board of Directors of Perot on or before the
     date of receipt of the notice of the proposed sale or transfer.

5.   Compliance with Securities Laws.

     (a) Participant acknowledges that the option evidenced by this Agreement
     and the shares to be issued upon exercise of the option have not been
     registered under the Securities Act of 1933, that Perot Systems has no
     present intention to so register them, that such shares may be deemed
     "restricted securities" under Rule 144 of the Act, that the holder of
     restricted securities may be required to hold them for an indefinite period
     of time unless they are registered for sale under the Act or an exemption
     from registration is available, and that routine sales of restricted
     securities under Rule 144 can only be made if Perot Systems meets certain
     requirements, including a requirement to make certain information publicly
     available, and then only in limited amounts and in a specified manner in
     accordance with the terms and conditions of Rule 144.

     (b) Upon demand by Perot Systems, any person exercising the option
     evidenced by this Agreement, at the time of such exercise, will deliver to
     Perot Systems a written representation to the effect that the shares being
     acquired are being acquired for investment and not with a view to any
     resale or distribution thereof.

     (c) Neither Participant nor any successor in interest of Participant will
     sell or otherwise transfer the option evidenced by this Agreement or any
     shares acquired upon exercise of the option in any way that might result in
     a violation of any federal or state securities laws or regulations.

     (d) Perot Systems may require Participant or any subsequent holder of the
     option or of any shares acquired upon exercise of the option to provide
     Perot Systems, before any sale or other transfer, with such
     representations, commitments, and opinions regarding compliance with
     applicable securities laws and regulations as Perot Systems may deem
     necessary or advisable.

6.   Stock Certificates; Rights as Shareholder. Perot Systems will retain for
     safekeeping all certificates representing shares purchased upon exercise of
     the option evidenced by this Agreement. Each such certificate will bear
     such legends as the Board



                                     - 4 -
<PAGE>   9

     determines are necessary or appropriate. Whether or not certificates
     representing such shares have been issued or delivered, Participant will
     have all the rights of a shareholder of Common Stock, including voting,
     dividend and distribution rights, with respect to such shares owned by
     Participant. Participant will not have any rights as a shareholder with
     respect to any shares subject to the option before the date of issuance to
     Participant of shares upon exercise of the option.

7.   Income Tax Withholding. Participant (or any person entitled to act on
     Participant's behalf) shall, upon request by the Company, pay to Perot
     Systems, or Perot Systems may withhold from sums or property otherwise due
     or payable to Participant (or such person), such amount as Perot Systems
     may request for the purpose of satisfying any liability to withhold
     federal, state, local, or foreign income or other taxes. If shares of stock
     are withheld for such purpose, they will be withheld at fair market value,
     as defined in Section 1(c), as of the date of accrual of the liability.

8.   Compliance with Plan. Participant acknowledges receipt of a copy of the
     Plan and further acknowledges that this Agreement is entered into, and the
     option has been awarded, pursuant to the Plan. If the provisions of the
     Plan are inconsistent with the provisions of this Agreement, the provisions
     of the Plan govern and supersede the provisions of this Agreement.

9.   Notices. Any notice to Perot Systems or the Company that is required or
     permitted by this Agreement shall be addressed to the attention of the
     Secretary of Perot Systems at 12377 Merit Drive, Suite 1100, Dallas, Texas
     75251. Any notice to Participant that is required or permitted by this
     Agreement shall be addressed to Participant at the most recent address for
     Participant reflected in the appropriate records of the Company. Either
     party may at any time change its address for notification purposes by
     giving the other written notice of the new address and the date upon which
     it will become effective. Whenever this Agreement requires or permits any
     notice from one party to another, this notice must be in writing to be
     effective and, if mailed, shall be deemed to have been given on the third
     business day after the same is enclosed in an envelope, addressed to the
     party to be notified at the appropriate address, properly stamped, sealed,
     and deposited in the United States mail, and, if mailed to the Company, by
     certified mail, return receipt requested.

10.  Remedies. Perot Systems is entitled, in addition to any other remedies it
     may have at law or in equity, to temporary and permanent injunctive and
     other equitable relief to enforce the provisions of this Agreement. Any
     action to enforce the provisions of, or otherwise relating to, this
     Agreement may be brought in the state or federal courts having jurisdiction
     in Dallas, Dallas County, Texas. By signing



                                     - 5 -

     this Agreement, Participant consents to the personal jurisdiction of such
     courts in any such action.

11.  Assignment. This Agreement shall inure to the benefit of and be binding
     upon the parties hereto and their respective heirs, personal
     representatives and permitted successors and assigns. However, Participant
     does not have the power or right to assign this Agreement without the prior
     written consent of Perot Systems.

12.  Attorneys' Fees. If any action at law or in equity is necessary to enforce
     or interpret the terms of this Agreement, the prevailing party will be
     entitled to reasonable attorneys' fees, costs, and necessary disbursements
     in addition to any other relief to which that party may be entitled.

13.  Severability. If any provision of this Agreement is held invalid or
     unenforceable for any reason, the validity and enforceability of all other
     provisions of this Agreement will not be affected.

14.  Headings. The section headings used herein are for reference and
     convenience only and do not affect the interpretation of this Agreement.

15.  Governing Law. This Agreement shall be governed by and construed in
     accordance with the law of the State of Texas, without regard to that
     state's choice of law rules.

16.  Entire Agreement. This Agreement, together with the Plan and any rules and
     regulations adopted by the Board or Committee thereunder, constitutes the
     entire agreement between the parties with respect to its subject matter.

17.  Amendment. This Agreement may be amended only in a manner that is
     consistent with the Plan and only by a written instrument signed by both
     Perot Systems and Participant.

IN WITNESS WHEREOF, and intending to be legally bound hereby, Participant and a
duly-authorized representative of Perot Systems have executed this Agreement as
of the date first above written.
