SWISS BANK CORPORATION

     In January 1996, the Company formed a strategic alliance with Swiss Bank
Corporation ("Swiss Bank") which involved (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 new terms are effective from January 1,
1997 and involve (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 continues to hold 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.

     The following summary of the principal Swiss Bank Agreements is qualified
in its entirety by reference to such agreements, copies of which are attached
hereto as Exhibits 10.30, 10.31 and 10.32.

Master Operating Agreement

     The Amended and Restated Master Operating Agreement, dated as of January
1, 1997, between the Company and Swiss Bank (the "Master Operating Agreement"),
contains the standard terms and conditions that apply to all agreements ("EPI
Agreements") pursuant to which the Company provides or may, in the future,
provide operational management services to Swiss Bank and its affiliates. The
Master Operating Agreement has an indefinite term; however, it may be
terminated by either party on or after December 31, 2008. In addition, the
Company may terminate the Master Operating Agreement and certain EPI Agreements
for cause, non-payment, Swiss Bank's insolvency and certain cross-defaults.
Swiss Bank may terminate the Master Operating Agreement and certain EPI
Agreements for cause, the Company's insolvency, a change in control of the
Company, the Company's discontinuance of its provision of IT services, certain
cross-defaults, the occurrence of certain significant events at Swiss Bank and
the Company's non-compliance with Swiss Bank's security procedures.

SBC Warburg EPI Agreement

     The Amended and Restated Agreement for EPI Operational Management, dated
as of January 1, 1997, between Swiss Bank and the Company (the "SBC Warburg EPI
Agreement"), governs the relationship between Swiss Bank and the Company with
respect to SBC Warburg. The SBC Warburg EPI Agreement requires that Swiss Bank
obtain from the Company SBC Warburg's requirements for the operational
management of its technology resources (including mainframes, desktops, and
voice and data networks), excluding hardware and proprietary software
applications development. The term of the SBC Warburg EPI Agreement is 10 years
beginning January 1, 1997.

     The Company's charges for services provided under the SBC Warburg EPI
Agreement are generally based on reimbursement of all costs, other than Company
corporate overhead, incurred by the Company in the performance of services for
SBC Warburg. In addition, the Company will receive an agreed annual amount
subject to bonuses and penalties related to the Company's performance on
certain defined metrics.

PSC Stock Agreement

     Pursuant to the Amended and Restated PSC Stock Option and Purchase
Agreement, dated as of April 24, 1997 (the "PSC Stock Agreement"), the Company
issued and sold to Swiss Bank options (the "SBC Options"), including options to
purchase 3,617,160 shares of the Company's nonvoting Class B Common Stock, par
value $.01 per share ("Class B Common Stock," and such shares, "Class B
Shares") at a purchase price of $2.25 per option       



                                       4
<PAGE>   6


share (the "SBC Warburg Options"). The Company also issued and sold to Swiss
Bank 50,000 Class B Shares at a purchase price of $7.30 per share (the "SBC
Warburg Shares"). Subject to regulatory limits, the SBC Warburg Options are
exercisable immediately and from time to time until they expire at an exercise
price of $7.30 per share. The SBC Warburg Options expire five years after they
vest; provided that the five-year periods are tolled during any time that
ownership restrictions prevent Swiss Bank from exercising such options.

     The SBC Warburg Options and the SBC Warburg Shares were issued and sold in
connection with the execution and delivery of the SBC Warburg EPI Agreement.
The SBC Warburg Options and the SBC Warburg Shares continue to vest at a rate
of 31,953 shares per month for the first five years of the SBC Warburg EPI
Agreement and at a rate of 29,167 shares per month thereafter. In the event of
termination of the SBC Warburg EPI Agreement for any reason, (i) all unvested
SBC Warburg Options will be terminated and (ii) Swiss Bank will deliver to the
Company, against the payment of the purchase price of $7.30 per share, title to
all unvested SBC Warburg Shares.

     Pursuant to the PSC Stock Agreement, the Company also agreed to issue and
sell to Swiss Bank, upon the occurrence of the "SBC Domestic Event", additional
SBC Options (the "SBC Domestic Options") and/or Class B Shares (the "SBC
Domestic Shares"), for an aggregate total of 3,500,000 SBC Domestic Options and
SBC Domestic Shares, in such combination of options and shares to be determined
in the discretion of Swiss Bank. The "SBC Domestic Event" means the entering
into by the Company and Swiss Bank, on or prior to December 31, 1998, of a
definitive agreement, having a term of 10 years and a similar scope and size to
the SBC Warburg EPI Agreement, relating to Swiss Bank apart from SBC Warburg,
including such terms and conditions consistent with those set forth in the SBC
Warburg EPI Agreement as may be agreed upon by the Company and Swiss Bank (the
"SBC Domestic Agreement").

     The purchase price for the SBC Domestic Options will be an amount per
share equal to a defined fair value for the SBC Domestic Options as of
the date of the occurrence of the SBC Domestic Event. The exercise price per
share for the SBC Domestic Options will also be the defined fair value per 
share as of the date of grant. The SBC Domestic Options expire five years after
they vest; provided that the five-year periods are tolled during any time that
ownership restrictions prevent Swiss Bank from exercising such options.

     SBC Domestic Options and SBC Domestic Shares will vest ratably over 10
years commencing on the SBC Domestic Event, and will continue to vest until the
SBC Domestic Agreement is terminated. In the event of termination of the SBC
Domestic Agreement for any reason, (i) all unvested SBC Domestic Options will
be terminated and (ii) Swiss Bank will deliver to the Company, against payment
therefor, per share of the purchase and exercise price for the SBC Domestic
Options, all unvested SBC Domestic Shares.

     The SBC Warburg Options and the SBC Domestic Options will generally be
exercisable immediately upon grant. Swiss Bank is, however, subject to certain
regulatory limitations upon its exercise of SBC Options. After giving effect to
any purchase of SBC Options, purchase of Class B Shares and exercise of SBC
Options by 


                                       5

Swiss Bank, (i) the number of Class B Shares owned by Swiss Bank
(including any Class B Shares then owned by any employee of Swiss Bank),
together with the number of any Class B Shares owned by Swiss Bank at any time
prior to such exercise, may not exceed 10% of the number of shares of Common
Stock outstanding, and (ii) the aggregate purchase and exercise prices paid by
Swiss Bank on the acquisition of Class B Shares and exercise of SBC Options may
not exceed 10% of the consolidated stockholders' equity of the Company. If,
however, on certain specified anniversaries of the date of the PSC Stock
Agreement, beginning in 2004 (each, a "Trigger Date"), the number of Class B
Shares for which SBC Options are exercisable is limited because an insufficient
number of the shares of Common Stock are outstanding, Swiss Bank has, subject
to certain exceptions, the right to initiate certain procedures to eliminate
such deficiency. These procedures may result in the Company issuing additional
Common Stock and Swiss Bank requesting that the Federal Reserve Board approve
an increase in the percentage of Common Stock of the Company that Swiss Bank
may own or the Company purchasing shares of Class B Stock from Swiss Bank at
the then fair market value defined in the SBC Stock Agreement.

     Swiss Bank may not sell or otherwise transfer any Options or any Class B
shares that have not vested. In addition, subject to certain exceptions, the
PSC Stock Agreement restricts the right of Swiss Bank to transfer Class B
Shares (i) within certain periods surrounding an IPO or (ii) if the transfer
would contravene applicable banking law. In addition, in certain limited
circumstances, the Company has a right of first refusal to purchase Class B
Shares that Swiss Bank desires to sell.

RELIANCE ON MAJOR CLIENTS

     During the year ended December 31, 1996, approximately 28% 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 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. See "- Swiss Bank Corporation."

     The Company's two most significant clients (after Swiss Bank) accounted
for an aggregate of approximately 15% of the Company's contract revenues during
the year ended December 31, 1996. Neither of these clients accounted for more
than 10% of the Company's contract revenues. The loss of one or more of these
clients could have a material adverse effect on the Company's business,
financial condition and results of operations.

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
("IBM"), Andersen Consulting LLP, Computer Sciences Corporation and Electronic
Data Systems Corporation. Each of these companies, as well as some other
competitors, has greater financial, technical, sales and marketing resources,
greater name recognition and a larger customer base 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.

MERGERS AND ACQUISITIONS

     In the second half of 1996 and the first quarter of 1997, the Company
consummated several acquisitions which contributed technical personnel and
expertise in specific technologies and markets as well as certain in-process
technologies. None of these acquisitions was material in the context of the
Company taken as a whole. The Company continually evaluates the possibility of
further acquisitions and intends to continue to complement its internal growth
through acquisitions and other business affiliations.

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

EMPLOYEES

     As of March 31, 1997, the Company employed approximately 4,900 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.

                    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.

OVERVIEW

     The Company is an IT services and business transformation company helping
clients devise, plan, implement and manage business and IT solutions. The
services offered by the Company include systems integration, systems operation
and software development, as well as business and IT consulting. The Company's
clients represent a broad range of industries, including financial services,
healthcare, communications and media, energy, manufacturing and travel and
transportation.

RESULTS OF OPERATIONS

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. The primary growth factor was an increase in revenue from
sales to new clients, including $168.9 million generated by the Swiss Bank
Agreements. In addition, $20.8 million of total contract revenue in 1996
resulted from the expansion of a contract with an existing client that merged
with another entity and $10.7 million of total contract revenue in 1996 was
related to businesses acquired during 1996. The remaining contract revenue
increase of $56.7 million was related to growth in short-term project
engagements, expansion of business with existing clients and the addition of
new clients (other than Swiss Bank).

     Domestic contract revenue increased in 1996 by 53% to $365.2 million from
$238.8 million in 1995 due to the recognition of $53.9 million in domestic
Swiss Bank revenue and 30% growth in other domestic business. The growth in
non-Swiss Bank domestic business was due to the factors discussed in connection
with the growth of total contract revenue above. Domestic contract revenue
declined as a percentage of total contract revenue to 61% from 70% in 1995 due
to Swiss Bank contract revenue, of which $159.6 million was earned in Europe
and $9.3 million in Asia.

     Non-domestic contract revenue, which included European and Asian
operations, increased in 1996 by 126% to $234.2 million from $103.5 million in
1995, due in large part to the previously discussed Swiss Bank revenue. As a
result, non-domestic contract revenue grew in 1996 to 39% of total contract
revenue in 1996 from 30% in 1995. For additional information on the geographic
breakdown of revenue, see Note 12 to the Consolidated Financial Statements,
"Certain Geographic Data and Segment Information".


                                       9
<PAGE>   11


     Direct cost of services increased in 1996 by 73% to $465.1 million from
$268.6 million in 1995. The increase in the direct cost of services was
primarily the result of growth in the Company's business. In addition, direct
cost of services were increased by a $4.2 million write-off of software license
transfer rights and a $3.9 million write-off of purchased research and
development expenses in connection with 1996 business acquisitions accounted
for under the purchase method. Selling, general and administrative expenses
("SG&A") increased in 1996 by 76% to $92.9 million from $52.9 million in 1995,
due to the addition of key executives, expansion of the sales force, and staff
growth in administrative support areas such as communications, finance, human
resources, legal, strategy, marketing, resourcing and internal systems.

     Operating income nearly doubled in 1996 to $41.4 million from $20.9
million in 1995, reflecting business growth and other factors previously
discussed in connection with revenue, direct cost of services and SG&A.
Operating margin increased in 1996 to 6.9% from 6.1% in 1995 due to a decline
in direct cost of services as a percentage of contract revenue in 1996 to 77.6%
from 78.5% in 1995. The after tax margin increased in 1996 to 3.4% from 3.2% in
1995.

     The effective tax rate increased in 1996 to 48.9% from 46.6% in 1995, due
primarily to an increase in non-deductible expense items.

Comparison of the year ended December 31, 1995 to the year ended December 31,
1994

     Contract revenue increased in 1995 by 17% to $342.3 million from $292.2
million in 1994, primarily as a result of growth in sales to new clients. This
net increase in contract revenue was reduced by $24.3 million due to the April
1995 restructuring of a facilities management contract with NationsBanc
Services, Inc. ("NBS," and such contract, the "NBS Agreement"). Under the terms
of the NBS Agreement, the Company received $12.0 million as prepayment for
services to be rendered over four years. The Company is recognizing this
prepayment ratably over the four-year term of the contract. In addition, the
Company transferred property, equipment and purchased software to the client
for $5.8 million, representing the approximate net book value of the assets.

     Domestic contract revenue increased in 1995 by 23% to $238.8 million from
$193.9 million in 1994. Offsetting a $24.3 million decline in 1995 from the
restructuring of the NBS Agreement, revenue from other domestic contracts
increased by $69.2 million, or 52% due primarily to growth in short-term
project sales to new clients. For 1995 and 1994, domestic contract revenue
represented 70% and 66%, respectively, of total contract revenue.

     Non-domestic contract revenue increased in 1995 by 5% to $103.5 million
from $98.3 million in 1994. As a percentage of total contract revenue,
non-domestic contract revenue declined in 1995 to 30% from 34% in 1994,
primarily because two major European software development projects were
completed in 1994, after which the 


                                      10
<PAGE>   12


Company's services to these clients became more operational in nature. The net
impact of this change on 1995 contract revenue was a decrease of $18.9 million.
For additional information on the geographic breakdown of revenue, see Note 12
to the Consolidated Financial Statements, "Certain Geographic Data and Segment
Information".

     Direct cost of services as a percentage of contract revenue declined in
1995 to 78% from 84% in 1994, due to growth in short-term consulting projects,
a larger concentration of operations staff in sales roles, and the
restructuring of the NBS Agreement. SG&A increased as a percentage of revenue
to 15% in 1995, from 14% in 1994, due to a larger use of operations staff in
sales roles.

     Operating income nearly doubled in 1995 to $20.9 million from $10.9
million in 1994, despite the fact that 1994 operating income included
recognition of a $6.7 million net gain from fees received in connection with
the December 1993 exercise of an IT services contract termination clause by
First American Bankshares, Inc. and its subsidiary banks ("FAB"). Upon exercise
of FAB's termination clause, the Company received a cash payment of $17.4
million, of which $7.4 million was used to cover 1994 expenses related to the
contract, and $3.3 million was accrued to cover estimated future facility lease
costs. Further, in 1994, the Company was successful in obtaining a more
favorable facility sublease arrangement than originally estimated, thereby
resulting in the recognition of a $6.7 million benefit from the termination
fee.

     Operating margin improved in 1995 to 6.1% from 3.7% in 1994 as a result of
the decline in direct cost of services as a percentage of contract revenue.
This was due to growth in higher margin short-term systems integration
projects, more efficient staff utilization and the restructuring of the NBS
Agreement. The after tax margin improved in 1995 to 3.2% from 2.2% in 1994. The
effective income tax rate increased in 1995 to 46.6% from 37.6% in 1994,
attributable primarily to the increase in certain non-deductible items.

LIQUIDITY AND CAPITAL RESOURCES

     Driven by Swiss Bank and other general business growth, cash flows from
operating activities increased in 1996 to $53.9 million from $24.0 million in
1995. Key growth factors underlying this increase included net income, accrued
liabilities and deferred revenue, the effects of which were partially offset by
growth in accounts receivable and deferred income taxes. Net income increased
in 1996 to $20.5 million from $10.8 million in 1995, and accrued liabilities
grew to $83.0 million in 1996 from $38.9 million in 1995, due to Swiss Bank
related expense growth. Deferred revenue increased in 1996 to $22.0 million
from $5.9 million in 1995, due to advance payments on new contracts and the
deferred recognition of a $5.1 million contract termination fee received in
1996 which will be recognized in 1997 as expenses associated with the
disposition of the contract are incurred. The impact of these net increases in
cash from operating activities was reduced because accounts receivable grew in
1996 to $113.8 million from $61.2 million in 1995 and because deferred income
taxes increased in 1996


                                      11
<PAGE>   13


to $30.5 million from $16.1 million in 1995. The accounts receivable growth
from 1995 to 1996 was due primarily to the significant increase in sales to new
clients, especially to Swiss Bank, which accounted for $26.5 million of the net
change. The increase in deferred income taxes from 1995 to 1996 was due
primarily to growth in accrued expenses not deductible in the current period.

     Cash flows from operating activities increased in 1995 to $24.0 million
from $1.3 million in 1994, reflecting business growth and the effect of a $12.0
million advance payment received in 1995, in connection with the restructuring
of the NBS Agreement. Although business growth caused accounts receivable to
grow by $34.2 million, this change was more than offset by related growth in
accrued liabilities, accounts payable and accrued compensation. Also,
depreciation and amortization declined by $6.5 million. Income tax payments
made in 1995 relating to 1994 tax liabilities were $0.2 million compared to
$9.4 million in income tax payments made in 1994 relating to 1993 tax
liabilities.

     Net cash used in investing activities increased in 1996 to $41.9 million
from $12.4 million in 1995 due to growth-related increases in capital
expenditures, a decline in asset sales, new businesses acquired and increased
investments in unconsolidated subsidiaries. In 1996, the Company increased its
investment in property, equipment and software to $27.5 million from $18.3
million in 1995, to accommodate overall staff growth of 50%. Cash paid in 1996
for business interests acquired was $15.0 million, of which $9.5 million was
used to acquire 100% equity interests in three IT services companies and one
business consulting firm, and $5.5 million was used to purchase minority
interests in other companies. These entities are expected to contribute
significant knowledge and new expertise to the Company's service offerings,
assist in the development of new products and software applications and to
provide new business opportunities. There can be no assurance that the acquired
businesses will provide new opportunities or that new products or software
applications will be developed or, if developed, successfully brought to
market. The Company is committed to investing a maximum of $16.6 million to
fund additional future capital requirements of the unconsolidated entities. The
actual amounts invested in these businesses will vary depending on their needs
for cash and the opportunities available to them. Cash proceeds on sales of
property, equipment and software declined in 1996 to $0.7 million from $6.0
million in 1995, reflecting no large asset sales in 1996, as opposed to 1995,
in which property, equipment and purchased software valued at $5.8 million was
sold in connection with the restructuring of the NBS Agreement.

     Net cash used in investing activities increased in 1995 to $12.4 million
from $10.1 million in 1994, reflecting a business growth related increase of
$8.0 million in capital expenditures, offset by an increase of $5.8 million in
cash proceeds on sales of property, equipment and software related to the
restructuring of the NBS Agreement.

     Net cash used in financing activities increased in 1996 to $4.5 million
from $3.6 million in 1995. In 1996, the Company redeemed 100% of its
outstanding Series A 




                                      12
<PAGE>   14


Preferred Stock for $8.5 million to eliminate dividends with no tax benefit.
Other significant cash changes included a $4.2 million increase in net proceeds
from the issuance of Class A Common Stock, which reflected a significant
increase in the exercise of stock options by employees in 1996. In addition,
there was a $2.1 million increase in repayments of stockholder notes
receivable, a $0.7 million decrease in debt and capital lease obligation
repayments, and a $0.6 million decrease in dividends paid on preferred stock.

     Net cash used in financing activities decreased in 1995 to $3.6 from $9.4
million in 1994, due primarily to reductions in repayments of debt and capital
lease obligations.

     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. See Note 13 to the
Consolidated Financial Statements, "Commitments and Contingencies".

     The Company increased its credit line in August 1996 to $40.0 million from
$10.0 million to fund general corporate purposes and potential business
acquisitions. As of December 31, 1996, there were no borrowings outstanding
under this line.

     The Company expects that its principal use of funds for the foreseeable
future will be for acquisitions, capital expenditures and working capital. In
addition, the Company expects to use funds for the development of in-process
software applications, which were acquired as part of the 1996 business
combinations. Capital expenditures may consist of purchases of computer and
related equipment and software. The Company anticipates that cash flows from
operating activities and unused borrowing capacity under its existing line of
credit will provide sufficient funds to meet its needs for the remainder of
1997. Significant growth in the Company's business in 1997 and 1998 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.

SWISS BANK ALLIANCE

     The Company experienced substantial growth in 1996. 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. The alliance
includes a long-term contract for the Company to deliver IT services to SBC
Warburg and the grant to Swiss Bank of the SBC Options. Pursuant to the terms
of the Swiss Bank Agreements, the Company also acquired a 40% interest in
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, 1996,
approximately 28% of the Company's revenues were earned in connection with
services performed on behalf of Swiss Bank and its affiliates. For more
information regarding the Swiss Bank alliance, see "Swiss Bank Corporation".

ITEM 3.  PROPERTIES.

     As of March 31, 1997, the Company had 28 locations in the United States
and five locations in three countries outside the United States. The Company
owns no real estate, and leased properties consist primarily of office and
warehouse facilities. Current leases have expiration dates that range from 1997
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.

     (1)  These amounts represent assumed rates of appreciation in market value
          from the date of grant until the end of the option term, at the rates
          set by the Securities and Exchange Commission and, therefore, are not
          intended to forecast possible future appreciation, if any, in the
          Class A Shares.

EMPLOYMENT CONTRACTS AND CHANGE IN CONTROL AGREEMENTS

     Morton H. Meyerson. Mr. Meyerson's assignee, the Meyerson Partnership,
purchased 4,000,000 Class A Shares from the Company pursuant to the terms of a
stock purchase agreement between Mr. Meyerson and the Company (the "MFLP
Agreement"). Under the MFLP Agreement, the Company has the right to repurchase
a portion of the Class A Shares held by the Meyerson Partnership if Mr.
Meyerson voluntarily resigns as Chairman unless the parties agree to an
arrangement for Mr. Meyerson to remain with the Company. The agreement provides
for a formula to determine how many Class A Shares the Company would have the
right to repurchase. The number of Class A Shares that the Company would have
the right to repurchase declines over five years from the date of the MFLP
Agreement. In June 1997, the Company's right to repurchase Class A Shares held
by the Meyerson Partnership will terminate.

     James. A. Cannavino. Mr. Cannavino's employment agreement with the Company
provides for a base salary of $500,000 per year, subject to adjustment from
time to time by the Board of Directors; provided, however, that a decrease in
Mr. Cannavino's base salary is grounds for Mr. Cannavino to terminate his
employment for good reason (as discussed below). Mr. Cannavino's employment
agreement provides for additional benefits, including: (i) cash bonuses that
may be paid in the discretion of the Board of Directors, (ii) payment of life
insurance premiums, (iii) relocation benefits and (iv) certain travel benefits.
Mr. Cannavino's employment agreement also provides that, in the event that the
Company terminates his employment other than for cause (as defined in the
agreement) or he terminates his employment agreement for good reason (as
defined in the agreement), Mr. Cannavino will receive a severance payment equal
to two years' 


                                      22
<PAGE>   24


base salary (computed using the highest base salary previously paid to him).
The second year's salary would be reduced by amounts earned by Mr. Cannavino
from other sources during that year unless termination of Mr. Cannavino's
employment occurred within six months of a change in control (as defined in his
employment agreement) of the Company.

     The 2,000,000 restricted Class A Shares acquired by Mr. Cannavino pursuant
to his stock option grant vest in equal installments over ten years beginning
on the first anniversary of the commencement of Mr. Cannavino's employment by
the Company. Vesting is contingent on continued employment; provided, however,
that Mr. Cannavino's restricted Class A Shares will continue to vest for
limited periods following the termination of his employment if such termination
is by the Company other than for cause (as defined in his employment agreement)
or by Mr. Cannavino for good reason (as defined in his employment agreement).
If Mr. Cannavino's employment is terminated without cause by the Company or for
good reason by Mr. Cannavino (except, in either case, if the termination is
related to a change in control of the Company (as defined in his employment
agreement)) on or before the vesting date for 1998, Mr. Cannavino's Class A
Shares will continue to vest through that vesting date, as scheduled. In the
event such a termination is not related to a change in control of the Company
and follows the vesting date for 1998, Mr. Cannavino's Class A Shares will
continue to vest through the vesting date following the termination of
employment, as scheduled. In addition, if there is a change in control of the
Company during Mr. Cannavino's employment or Mr. Cannavino's employment is
terminated prior to but in connection with a change in control of the Company,
Mr. Cannavino's Class A Shares will vest as follows: (i) if the termination or
change in control occurs on or before Mr. Cannavino's scheduled vesting date in
1999, all Class A Shares scheduled to vest through his vesting date in the year
2000 will immediately vest upon the change in control or termination or (ii) if
the termination or change in control occurs after Mr. Cannavino's scheduled
vesting date in 1999, all Class A Shares scheduled to vest through the next two
vesting dates will immediately vest upon the change in control or termination.
If the Class A Shares are not publicly traded prior to the year 2010, Mr.
Cannavino has the right to require the Company to repurchase his Class A Shares
at their then fair value.

     James Champy. Mr. Champy's associate agreement provides for a base salary
of $500,000 per year, which is to be reviewed at least annually by the Board of
Directors to determine whether such salary should be increased. Mr. Champy's
associate agreement provides for additional benefits, including: (i) a bonus to
be determined in accordance with the then current bonus plan applicable to the
most senior officers of the Company, (ii) payment of life insurance premiums
and (iii) certain travel benefits. Mr. Champy's associate agreement also
provides that, in the event that Mr. Champy is terminated by the Company other
than for cause or substantial misconduct (as defined in his associate
agreement) or Mr. Champy is deemed to have been constructively terminated (as
defined in his associate agreement), Mr. Champy will receive a severance
payment equal to (i) one year of Mr. Champy's then current base salary if such
termination occurs on or before August 12, 1997 or (ii) six months of Mr.
Champy's then current base salary if such termination occurs after August 12,
1997. If Mr. Champy's employment is 



                                      23
<PAGE>   25


terminated by either party (other than for cause by the Company) within one
year of a change in control of the Company (as defined in his associate
agreement), Mr. Champy would be entitled to receive a severance payment equal
to (i) one year of Mr. Champy's then current base salary if the change in
control occurs on or before August 12, 1997 or (ii) six months of Mr. Champy's
then current base salary if the change in control occurs after August 12, 1997.

     The 500,000 restricted Class A Shares acquired by Mr. Champy pursuant to
his restricted stock agreement vest in equal installments over ten years
beginning on the first anniversary of the commencement of Mr. Champy's
employment by the Company. Vesting is contingent on continued employment;
provided, however, that Mr. Champy's restricted Class A Shares will continue to
vest for limited periods following the termination of his employment if his
employment is terminated by the Company other than for cause or substantial
misconduct (as defined in his associate agreement) or Mr. Champy is deemed to
have been constructively terminated (as defined in his associate agreement). If
Mr. Champy's employment is terminated by the Company other than for cause or
substantial misconduct effective after August 12, 1997 and on or before August
12, 1998 or Mr. Champy is deemed to have been constructively terminated on or
before August 12, 1998, Mr. Champy's restricted Class A Shares will continue to
vest to and including the vesting date in 2000, as scheduled. If Mr. Champy's
employment is terminated by the Company other than for cause or substantial
misconduct or Mr. Champy is deemed to have been constructively terminated after
August 12, 1998, Mr. Champy's restricted Class A Shares will continue to vest
as scheduled for two years following termination of employment. If there is a
change in control of the Company (as defined in his associate agreement) and
Mr. Champy's employment is terminated within one year of such change in control
by either party (other than for cause by the Company), Mr. Champy's Class A
Shares will continue to vest as follows: (i) if the change in control occurs on
or before August 12, 1998, all Class A Shares scheduled to vest to and
including his vesting date in the year 2000 will vest on schedule or (ii) if
the change in control occurs after August 12, 1998, all Class A Shares
scheduled to vest through the next two vesting dates will vest on schedule. In
the event that Mr. Champy is terminated for any reason by either party, Mr.
Champy has the right to require the Company to purchase his shares for their
original cost plus simple interest at the rate of eight percent per year.

DIRECTOR COMPENSATION

     Directors receive no cash compensation for their service on the Board of
Directors or any committee of the Board of Directors, except that directors are
reimbursed for their reasonable out-of-pocket expenses associated with
attending Board of Directors and committee meetings. Except for Mr. Hahn, in
the past, upon their election to the Board of Directors, non-employee directors
(other than affiliates of Ross Perot) were offered either (i) the opportunity
to purchase 60,000 restricted Class A Shares or (ii) the grant of an option to
acquire 60,000 Class A Shares at a purchase or exercise price equal to the fair
value of such Class A Shares at the date of purchase or grant, which restricted
shares 




                                      24
<PAGE>   26


or options vest ratably over a five-year period. In April 1993, Mr. Hahn
purchased 200,000 restricted Class A Shares at a price equal to the fair value
of such shares at the date of purchase, which shares vest ratably over a
five-year period.

     In December 1996, the Company adopted the 1996 Non-Employee Director Stock
Option/Restricted Stock Plan (the "Non-Employee Director Plan"). The
Non-Employee Director Plan provides for the issuance of nonqualified stock
options or restricted stock to non-employee directors of the Company and any of
its majority-owned subsidiaries. The Non-Employee Director Plan is administered
by the Board of Directors, which has the authority to interpret the
Non-Employee Director Plan. Directors eligible to receive awards under the
Non-Employee Director Plan are those who are not employees of the Company
(other than Ross Perot, Jr.). Each eligible existing director will receive
comparable grants at completion of the original vesting schedule for such
director's current options or restricted shares. Grants are made, subject to
the discretion of the Chairman of the Board of Directors, upon election to the
Board of Directors for new directors and, for existing directors, at completion
of the original vesting schedule for the director's existing options or
restricted shares. The Non-Employee Director Plan provides for a grant to each
eligible director of (i) an option to purchase 30,000 Class A Shares or (ii)
the right to purchase 30,000 restricted Class A Shares. The exercise price of
options or the purchase price of restricted Class A Shares awarded under the
Non-Employee Director Plan must be at least equal to 100% of the fair value of
a Class A Share on the date of the award.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee of the Board consists of three non-employee
directors, Messrs. Fields, Segall and Ross Perot, Jr.

     On September 30, 1996, the Company redeemed the 4,000,000 shares of the
Company's Series A Preferred Stock, all of which was held by Ross Perot, the
managing general partner of HWGA, for a redemption price equal to the par value
of $2.125 per share plus all accrued and unpaid dividends, or an aggregate of
$8,797,500. In addition, effective September 30, 1996, HWGA converted its
16,000,000 shares of the Company's Liquidation Preference Common Stock to
16,000,000 Class A Shares. Ross Perot, Jr. is a general partner of HWGA.

ITEM 7.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

     The Company has entered into an agreement with PII pursuant to which the
Company licensed certain software from PII. The Company sublicensed such
software to The Witan Company L.P. ("Witan"). Witan has paid a license fee of
$1,000,000 directly to PII in connection with the license. The Company has a
separate contract with Witan to perform development work on the licensed
software. PII is an affiliate of Ross Perot, the managing general partner of
HWGA. Mr. Blasnik is the President of PII.


                                      25
<PAGE>   27


     The Company has loaned funds to each of James A. Cannavino, Susan Fairty,
Ron Nash and Guillermo G. Marmol in connection with the purchase by such
persons of Class A Common Stock from the Company. Each of such loans accrues
interest at the rate of eight percent per annum and is secured by the purchased
stock. As of March 31, 1997, the total amount outstanding for each such loan
(including accrued interest) was $1,546,224, $267,337 and $133,795 for Messrs.
Cannavino, Nash and Marmol, respectively, and $570,380 for Ms. Fairty. Such
amounts were the highest amounts outstanding with respect to such loans since
their inception.

     In addition to amounts loaned to Mr. Cannavino in connection with his
purchase of stock, the Company has agreed to loan Mr. Cannavino up to an
additional $2,415,000 secured by his Class A Shares. An initial advance of
$614,587 was made on March 11, 1996 and bears interest at the federal
applicable rate. The initial advance, in general, is non-recourse to Mr.
Cannavino, except with respect to the pledged stock. All advances (other than
the initial advance) are full recourse to Mr. Cannavino. On March 18, 1997, the
Company advanced Mr. Cannavino an additional $125,000 under this arrangement,
which advance bears interest at 7.25% per year. As of March 31, 1996, the total
amount outstanding (including accrued interest) relating to this these loans
was $819,042. During April 1997, the Company advanced Mr. Cannavino an
additional $1,146,685 pursuant to this agreement. Interest will accrue at the
rate of 7.25% per year with respect to these amounts. Any future advances will
bear interest at the greater of 7.25% and the federal applicable rate at the
time of the loan.

     The Company has also loaned Mr. Cannavino $1,000,000 in connection with
his purchase of a permanent residence in Dallas. This note is secured by a
mortgage on such residence and bears interest at 7.25% per year.

     Messrs. Marmol and Nash, Donald D. Drobny and Peter A. Altabef have
outstanding loans with NationsBank of Texas, N.A. ("NationsBank") in the
respective principal amounts of $350,000, $125,000, $207,868 and $126,400.
Interest accrues on all such loans at the rate of 9.50%. The Company has agreed
that it will, at the request of NationsBank, purchase such loans from
NationsBank for an amount equal to principal plus accrued and unpaid interest
if, by the later of June 30, 1998 or the maturity of the relevant note, the
Company has not had an initial public offering that results in the Class A
Shares being publicly traded. The maturity dates are February 26, 2000, July 1,
1998, July 1, 1998 and July 5, 1998 for amounts borrowed by Messrs. Drobny,
Marmol, Nash and Altabef, respectively. Each loan is secured by a pledge of
Class A Shares.

ITEM 8   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 


                                      26
<PAGE>   28


a material adverse effect on the Company's consolidated financial position or
results of operations.

ITEM 9. MARKET PRICE OF AND DIVIDENDS ON THE REGISTRANT'S COMMON EQUITY AND
        RELATED STOCKHOLDER MATTERS.

     There is no established trading market for the Class A Common Stock or any
other class of the Company's securities. As of April 2, 1997, there were 1,133
holders of the Class A Common Stock and no holders of Class B Common Stock. As
of April 2, 1997, the Company had outstanding options to purchase 16,293,868
Class A Shares and 10,500,000 Class B Shares. Pursuant to the amendment of the
Swiss Bank Agreements on April 24, 1997, the number of outstanding options to
purchase Class B Shares has been reduced to 3,617,160. The Company has not paid
dividends on its Class A Common Stock since the formation of the Company and
does not currently have any intention of doing so.

ITEM 10. RECENT SALES OF UNREGISTERED SECURITIES.

     The Company has issued 4,927,782 Class A Shares and options to purchase an
additional 17,457,434 Class A Shares to employees from January 1, 1994 to March
31, 1997. Class A Shares were sold at the fair value of such shares at the time
of sale and the exercise price of each option was the fair value at the time of
the grant of the option. The fair value ranged from $1.00 per share to $6.75
per share. The Company relied on Rule 701 promulgated under the Securities Act
of 1933, as amended (the "Securities Act"), or Section 4(2) of the Securities
Act with respect to all sales and offers of its securities to its employees and
directors.

     During the past 3 years, the Company has also issued 1,650,372 Class A
Shares in connection with the acquisition of a number of businesses by the
Company. The Company relied on Section 4(2) of the Securities Act with respect
to such issuances. Shares were issued at their fair value at the time of the
transaction. Fair value ranged from $3.25 per share to $4.90 per share.

     The Company issued SBC Options pursuant to the PSC Stock Agreement to
Swiss Bank in connection with the strategic alliance formed in January 1996.
See Item 1, "Description of Business - Swiss Bank Corporation -PSC Stock
Agreement" for the terms of such options. The Company relied on Section 4(2) of
the Securities Act in connection with the issuance of the options and the offer
of Class B Common Stock in connection therewith.

ITEM 11. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

CLASS A COMMON STOCK

     The Certificate of Incorporation of the Company (the "Certificate of
Incorporation") authorizes 100,000,000 Class A Shares. As of April 2, 1997, the
Company had issued and outstanding 39,245,748 Class A Shares held by 1,133
holders of record.

     Holders of Class A Common Stock are entitled to receive such dividends, if
any, as may be declared by the Board out of legally available funds. In the
event of the liquidation, dissolution or winding up of the Company, holders of
Class A Common Stock are entitled to share equally and ratably with the holders
of Class B Common Stock, based on the number of shares held, in the assets, if
any, remaining after payment of all of the Company's debts and liabilities.

     Holders of Class A Common Stock are entitled to one vote per share for
each share held of record on any matter submitted to the stockholders for a
vote. Any amendment to the Certificate of Incorporation, merger or
consolidation of the Company, sale, lease or exchange of all or substantially
all of the Company's property and assets or voluntary dissolution of the
Company that requires approval by the Company shareholders under Delaware law
must be approved by the affirmative vote of the holders of at least 66-2/3% of
the outstanding Common Stock of the Company entitled to vote thereon, and the
holders of at least 66-2/3% of the outstanding Common Stock of each class
entitled to vote thereon as a class. Class A Shares are neither redeemable nor
convertible, and the holders thereof have no preemptive rights to subscribe for
or purchase any additional shares of capital stock issued by the Company.

     The summary description of the relative rights and limitations of the
Class A Common Stock is qualified in its entirety by reference to the
Certificate of Incorporation and Bylaws of the Company (the "Bylaws").

CLASS B COMMON STOCK

     In addition to Class A Common Stock, the Certificate of Incorporation
authorizes 24,000,000 Class B Shares. As of April 2, 1997, the Company had no
Class B Shares issued and outstanding and 10,500,000 Class B Shares were
subject to outstanding options. Pursuant to the amendment of the Swiss Bank
Agreements on April 24, 1997, the number of outstanding options to purchase
Class B Shares has been reduced to 3,617,160. Swiss Bank Corporation is the
beneficial owner of all outstanding options to acquire Class B Common Stock.
For additional information on the potential issuance of Class B Shares pursuant
to the exercise of outstanding options, see Item 1, "Description of Business -
Swiss Bank Corporation -PSC Stock Agreement".


                                      28
<PAGE>   30


     Holders of Class B Common Stock will, when such shares are issued, be
entitled to receive such dividends, if any, as may be declared by the Board out
of legally available funds equally and ratably with the Class A Common Stock.
In the event of the liquidation, dissolution or winding up of the Company,
holders of Class B Common Stock are entitled to share equally and ratably with
the holders of Class A Common Stock, based on the number of shares held, in the
assets, if any, remaining after payment of all of the Company's debts and
liabilities.

     Class B Shares have no voting rights, except to the extent that the
Delaware General Corporation Law requires a vote of the Class B Common Stock
with respect to an amendment to the Certificate of Incorporation that would
increase or decrease the par value of the Class B Common Stock or alter or
change the powers, preferences or special rights of Class B Shares. The number
of authorized Class B Shares may be increased or decreased by the affirmative
vote of the holders of a majority of voting stock of the Company, voting as a
single class, without any vote by holders of the Class B Common Stock. Class B
Shares are not redeemable, and the holders thereof have no preemptive rights to
subscribe for or purchase any additional shares of capital stock issued by the
Company. Under the terms of the Certificate of Incorporation, Swiss Bank does,
however, have the right to purchase shares of capital stock of the Company in
certain circumstances under the terms of the PSC Stock Agreement.

     Each Class B Share is convertible, on a share for share basis, at the
option of the holder thereof, into one fully paid and nonassessable Class A
Share if such Class B Share is sold or otherwise transferred to a person not
affiliated with Swiss Bank and the sale or transfer is made in accordance with
certain conditions described in the Certificate of Incorporation.

ITEM 12. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     A director of the Company may not be personally liable to the Company or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived any improper personal
benefit. The provisions of the Certificate of Incorporation eliminating the
liability of directors for monetary damages do not affect the standard of
conduct to which directors must adhere, nor do such provisions affect the
availability of equitable relief. In addition, such limitations on personal
liability do not affect the availability of monetary damages under causes of
action based on federal law.

     The Certificate of Incorporation provides for indemnification of its
officers and directors to the fullest extent permitted by the Delaware General
Corporation Law. In addition, the Company provides director and officer
insurance coverage for the benefit of its directors and officers.


                                      29
<PAGE>   31


     In addition to provisions made by the Company, Mr. Blasnik is indemnified
for actions taken in his capacity as a director of the Company as part of his
employment arrangement with PII.

Report of Independent Accountants

To the Board of Directors of
Perot Systems Corporation:

     We have audited the accompanying consolidated balance sheets of Perot
Systems Corporation and Subsidiaries (the "Company") as of December 31, 1996
and 1995, 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, 1996. 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, 1996 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles.

                   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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 ----------

      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.

      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 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 five 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 $30,304
             through 1996, 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 $101,481 and $77,914, respectively as of December
             31, 1996, and $37,760 and $34,459, respectively, as of December
             31, 1995.

                  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 losses reflected in
             other expense were $1,715, $892 and $433 for the years ended
             December 31, 1996, 1995 and 1994, respectively.

           Earnings per common share

                  Earnings per common share has been computed by dividing net
             income, less preferred stock dividend requirements, by the
             weighted average number of shares of common stock and common stock
             equivalents outstanding, when dilutive.  Common stock equivalents
             include the weighted average number of shares issuable upon the
             assumed exercise of outstanding stock options, assuming the
             applicable proceeds from such exercise, increased by the estimated
             tax benefit of assumed option exercises, are used to acquire
             outstanding shares.  In accordance with the modified treasury
             stock method, shares assumed acquired were limited in each period
             to 20% of the shares outstanding at the end of the period. Excess
             proceeds not utilized to repurchase shares are assumed invested at
             a yield of 5.1%, the 1996 average short term investment rate, and
             net income is increased by the interest assumed earned, net of
             tax, under this provision for the purpose of calculating earnings
             per share.  Fully diluted earnings per share are the same as
             primary earnings per share for all periods presented.

      Concentrations of credit risk

                  Financial instruments which potentially subject the Company
             to concentrations of credit risk consist of cash and cash
             equivalents and accounts receivable.  The Company's cash
             equivalents consist primarily of short-term money market deposits.
             The Company has deposited its cash and 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.

                  At December 31, 1996, one customer accounted for 27% of the
             Company's accounts receivables. At December 31, 1995, no customers
             exceeded 10% of the Company's accounts receivables.

      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.

      Treasury stock

                 Treasury stock transactions are accounted for under the cost
            method.

      Reclassifications

                 Certain of the 1995 and 1994 amounts in the accompanying
            financial statements have been reclassified to conform to the
            current presentation.

      Accounting for Stock Based Compensation

                 The Financial Accounting Standards Board issued Statement of
            Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for
            Stock Based Compensation", effective for fiscal years beginning
            after December 15, 1995.  SFAS 123 allows companies which grant
            employee stock options a choice to either continue current
            accounting treatment under Accounting Principles Board Opinion No.
            25 ("APB 25"),  "Accounting for Stock Issued to Employees", or adopt
            a new set of fair value accounting rules for recognizing
            compensation expense related to employee stock and stock option
            awards.  The Company elected to continue reporting pursuant to the
            provisions of APB 25.

      Accounting standard issued

                 In February 1997, the Financial Accounting Standards Board
            issued 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.  SFAS 128 also
            eliminates the modified treasury stock method, and requires
            reconciliation of the numerator and denominator used in computing
            basic and diluted earnings per share.  The Company has not yet
            determined the effect of SFAS 128 on the Company's earnings per
            share.

</TABLE>


           With regard to amounts billed, allowances for doubtful accounts are
      provided based on specific identification where less than full recovery
      of accounts receivable is expected.  Amounts to be invoiced represent
      revenue contractually earned for services performed, which are invoiced
      to the customer in the following month.  Recoverable costs and profits
      represent amounts previously recognized as revenue, that have not yet
      been billed, in accordance with the contract terms.  In certain cases,
      the period of recovery may extend beyond one year.  However,
      classification of these amounts within current assets has been made in
      accordance with common industry practice.  It is anticipated that $6,892
      of the recoverable costs and profits as of December 31, 1996 will be
      billed in 1997 and $852 will be billed in 1998.   Rebillable costs are
      amounts paid by the Company for goods and services on behalf of its
      customers.

           The significant increase in computer equipment in 1996 is attributed
      to the investment in new integrated corporate information systems and
      general business growth throughout the year.  The decrease in software in
      1996 is attributable to the write-off of assets placed into service from
      the Company's March 1993 software license transfer rights agreement.

4.    Acquisitions

           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.

           The 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, 1996 are included in the accompanying 1996
      consolidated statement of operations.  The dates of the 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, a portion of the CommSys purchase price and the TRC purchase
      price was allocated to in-process product development that had not
      reached technological feasibility and had no probable alternative future
      uses, which the Company recorded as direct cost of services at the date
      of acquisition.

           Under the terms and conditions of the various acquisition
      agreements, the Company paid a total of $9,669 in cash and issued
      1,460,372 shares of the Class A Common Stock valued at $6,545 for a total
      purchase price of $16,214.  The Company allocated the total purchase
      price to $4,286 of the tangible net assets acquired, $3,948 of expensed
      in-process product development and $7,980 of goodwill.

      and 1995, respectively or of future operations of the combined companies

5. Investments in Unconsolidated Affiliates

           At December 31, 1996, 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.  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 is
      required to contribute additional capital to HCL up to a limit of $6,900,
      on a call basis.  The Company's investment in HCL and Systor at December
      31, 1996 was $524 and $2,266, respectively.  No dividends or
      distributions were received from investments in unconsolidated affiliates
      in 1996 or 1995.

           In May 1996, the Company purchased 1,471,000 shares of a class of
      preferred stock for $2,500, which currently represents a 12% equity
      interest in a software company.  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 total commitment of up to
      $1,000.

                                 ----------


           In April 1996, the Company entered into an agreement to join a
      limited partnership venture capital fund.  The Company has committed to
      invest up to a total of $10,000, or a 2.75% interest, over a five-year
      period in connection with this agreement.  As of December 31, 1996,
      $1,292 in capital contributions have been made by the Company.  Capital
      contributions are used to fund the partnership's investment in companies
      specializing in information technology, telecommunications, and travel
      and leisure.

6.    Other Assets

      Software license transfer rights

           In March 1993, the Company entered into an agreement to obtain
      software license transfer rights for the purpose of lowering its future
      direct costs of service relating to the acquisition, operation or
      transfer of mainframe data-processing contracts.  The original cost of
      the transfer rights was $7,552.  The cost of the rights was divided into
      five equal assets, whereby one-fifth of the original cost would be placed
      in service each year over a five year period.  As of December 31, 1995,
      $4,530 of the rights had been placed in service.  During 1996, an
      additional $1,511 was placed into service with $1,511 of software license
      transfer rights remaining.

           In July 1996, the Company determined that these rights and assets
      placed in service 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.

      Goodwill

           Total goodwill related to the Company's acquisitions of $7,294, net
      of accumulated amortization of $686, is recorded as other noncurrent
      assets as of December 31, 1996.

7.    Line of Credit

           Effective July 31, 1996, the Company established a 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, 1996.  This
      facility expires July 31, 1998.


8.   Accrued Liabilities

     Accrued liabilities consist of the following as of December 31:

                                                  =======  =======
</TABLE>


      Operating expenses

           The largest increase in operating expense related accrued
      liabilities was due to Swiss Bank which, as of December 31, 1996 and
      1995, accounted for $26,696 and $363, respectively.

      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 the
      customer for services that require additional effort and costs by the
      Company to satisfy contractual requirements.

           In 1993, a client was acquired by another entity, whose management
      chose to exercise the termination clause in the client's contract with
      the Company.  As a result, the Company received a cash payment of $17,400
      in December of 1993.  As of December 31, 1993, the Company established an
      accrual for estimated future lease, service contract and asset
      disposition costs in the amount of $16,224 by deferring recognition of
      the cash termination payment.  During 1994, $7,433 of the cash
      termination payment was utilized to offset expenses related to the
      contract.  Further, in 1994, the Company was successful in obtaining a
      more favorable facility sublease arrangement than originally estimated,
      thereby resulting in the recognition of a $6,697 benefit from the
      termination fee.

9. Capital Lease Obligations and Long-Term Debt

           Capital lease obligations and long-term debt consist of the

      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 39,630,487 shares issued and outstanding as of December 31,
      1996.  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 shares of Class
      A Common Stock.  The Company is authorized to issue, under its existing
      stock plans, up to 37,400,000 shares of Class A Common Stock, of which
      23,630,487 are outstanding at year end.  In addition, 24,000,000 Class A
      shares are reserved for future conversion of Class B shares.

           Class B Common Stock ("Class B") of the Company consists of
      24,000,000 authorized shares of $0.01 par value common stock, of which
      none were issued at year end.  The Class B shares were authorized in
      conjunction with the provisions of a major new contract, which was signed
      in January 1996.  Class B shares are non-voting and convertible, but
      otherwise are equivalent to the Class A shares.

           Each share of Class B Common Stock shall be converted, at the option
      of the holder, on a share for share basis, into a fully paid and
      non-assessable share of Class A Common Stock, 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 Common Stock;  2) to a purchaser
      of Class A Common Stock 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
      a certain regulatory agency of the U.S. Government.

      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 Common Stock 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 an underwritten public
      offering of its Class A Common Stock registered with the Securities and
      Exchange Commission, the Company retains the right of first refusal to
      buy the employees' vested and unvested shares at a formula price set
      forth in each agreement, based on fair value, book value or the
      employees' cost plus interest at 8%.  After such an offering, 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%, or fair value.  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 Common Stock 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 Common Stock, 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 canceled following the expiration of a certain period after
      the employee leaves the employment of the Company.  Prior to an
      underwritten public offering of its common stock, the Company has certain
      rights of first refusal to repurchase employees' shares obtained through
      exercise of the stock options at either fair value or the employees' cost
      plus 8%.  Options issued after April 1, 1996 may not be exercised until
      the earlier of an initial public offering of the Company's common stock,
      or January 1, 1999.

      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 Common 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 supersede and replace the
      Advisor Plan.  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 common 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 will be the fair
      value of the shares at the date of issuance.  Other restrictions would be
      established upon issuance.  There were no issuances under the Director
      Plan in 1996.

      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 common 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
      will be the fair value of the shares on the date of grant.  The purchase
      price for share issuances will be determined by a committee appointed by
      the Board of Directors.  The fair value of issuances under the plan will
      be estimated at the time of issuance and amortized ratably over the
      vesting period as compensation expense.  There were no issuances under
      the Consultant Plan in 1996.

      Other stock and option activity

           During 1995, options for the purchase of 2,000,000 shares of Class A
      Common Stock, with an exercise price of $1.00 per share, were granted to
      an 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 is recorded as a reduction to stockholders' equity and is being
      amortized as compensation expense over the vesting period of ten years.
      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.  The note bears interest
      at 8% or a market rate defined in the agreement, whichever is greater,
      and with principal and interest due in full on the earlier of:  1) the
      fifteenth anniversary of the effective date;  2) three years after the
      stock is publicly traded; or  3) when the fair value of the vested shares
      is equal to or greater than two times the outstanding principal and
      interest balance of the promissory note.   The agreement provides for
      vesting ratably over a ten year period and establishes a two-year holding
      period on one-half of the shares prior to the sale of vested shares.

           The shareholder has voting, dividend and distribution rights with
      respect to both vested and unvested shares.  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 has the right, under certain circumstances, to
      repurchase certain shares at cost if employment with the Company
      terminates.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 ----------


           On January 5, 1996, the Company entered into a series of agreements
      with Swiss Bank.  These agreements included an information processing, a
      stock option and a stock purchase agreement, among the various associated
      contracts, all of which were effective as of January 1, 1996.  Under the
      terms and conditions of the stock option agreement, the Company granted
      the customer an option to acquire 10,500,000 shares of Class B Common
      Stock at a price of $2.50 per share.  In return, the company received a
      twenty-five year information processing agreement, a 40% interest in the
      voting common stock of the customer's information systems subsidiary
      ("Systor"), the right to utilize certain infrastructure and restricted
      applications to process other third party contracts, and a commitment for
      future project work for the customer.  Stock options to acquire 9,000,000
      shares vest ratably over 13 years beginning on January 1, 1998.  The
      start date of this 13 year vesting period can potentially be adjusted to
      either January 1, 1996, or January 1, 1994, upon termination of the
      contract by certain defaults of the Company.  Either early vesting
      scenario would accelerate the overall vesting of shares, but would not
      change the length of the vesting period or the annual rate of vesting.
      Stock options to acquire the remaining 1,500,000 shares vest ratably over
      13 years beginning on January 1, 1996, with no adjustment of the vesting
      period possible.  In the event of a termination of the information
      processing agreement, the Company will return a portion of the Systor
      shares based on the time elapsed since the signing of the information
      processing agreement.  The number of shares to be returned to Swiss Bank
      declines ratably over a period of thirteen years beginning January 1,
      1996.  The Company believes that the likelihood of a termination of the
      information processing agreement is remote.

           The stock option agreement provides that the Company will pay to
      Swiss Bank the excess of (a) the aggregate exercise price paid by Swiss
      Bank (up to $5.00 per share) for all shares purchased by Swiss Bank prior
      to the eighth, eleventh, fourteenth, seventeenth and twentieth
      anniversary dates ("Trigger Dates") of the stock option agreement and
      subsequent to the immediately preceding Trigger Date (or, in the case of
      the first Trigger Date, subsequent to the execution of the stock option
      agreement) (a "Trigger Date Period") over (b) the (i) number of the
      Calculation Base Shares (as defined below) times (ii) a defined fair
      value.  Swiss Bank will pay to the Company the excess of (a) (i) the
      number of the Calculation Base Shares (as defined below), multiplied by
      (ii) the defined fair value of a share of Class A Common Stock of the
      Company ("Class A Common Stock", and such shares, "Class A Shares") over
      (b) the aggregate exercise price paid by Swiss Bank (up to $5.00 per
      share) for all shares purchased by Swiss Bank

      during the relevant Trigger Date Period.  "Calculation Base Shares" means
      five percent of such shares purchased by Swiss Bank during the Trigger 
      Date Period ending on such Trigger Date.

           The value of the options granted was estimated to be $5,250, based
      upon an independent third-party appraisal.  Based upon their respective
      fair values, $706 was allocated to the equity interest acquired in
      Systor, and $4,544 to the value of contract rights received.  The
      contract rights are recorded as a reduction to stockholders' equity, and
      are being amortized ratably over the fifteen year vesting period.  Upon
      award, the underlying book value of the Company's acquired interest in
      Systor approximated $2,614, which exceeded the original estimated
      carrying value of $706.  The excess of $1,908 is being amortized as a
      reduction of direct expense over a three year period.  The full value of
      the options granted of $5,250 is recorded in additional paid-in-capital.

           The Company also granted the customer additional stock options to
      acquire up to 9,420,900 shares of Class B Common Stock if certain other
      information technology service agreements were executed on or before
      December 31, 1996.  As the agreements were not executed, the options
      expired December 31, 1996.

           Pursuant to the Bank Holding Company Act of 1965 (the "Act") and
      subsequent regulations and interpretations put forth by the Federal
      Reserve Board, the customer'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 the customer for the exercising its stock 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 on the eighth, eleventh, fourteenth, seventeenth, or twentieth
      anniversary date ("Trigger Dates") of the stock option agreement, the
      number of Class B shares for which the options are exercisable but
      limited from exercise by the Act, the Company will, within three years
      from the Trigger Date, issue additional shares to cure the limitation or
      purchase the shares which are limited at the fair value on the required
      date of payment.

           If, during the term of the SBC Warburg EPI Agreement, Swiss Bank

      shares or options in respect thereof to the Company for a price specified
      in writing.  If the Company does not accept such offer within 20 days of
      its such offer, Swiss Bank will be entitled to offer and sell the Class B

           All options issued by the Company in 1996 and 1995 were issued at
      the estimated fair value in effect at the date of issuance, vest ratably
      over the vesting period, and expire one year after the final vesting
      date.  The fair value of each option grant was estimated on the date of
      grant using the Minimum Value option pricing model with the following
      assumptions for 1996 and 1995, respectively;  risk free weighted average
      interest rates of 6.8% for both years; dividend yield and volatility of
      zero for both 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 1996 and 1995
      was $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.

     Income before taxes for the years ended December 31 was as follows:

           A valuation allowance has not been established for the net deferred
      tax asset as of December 31, 1996 or 1995, 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

      Deferred revenue

                  In 1996 a client was acquired by another entity, and the
             contract with the Company was terminated.  The Company received a
             cash payment of $5,100.  This payment was recorded as deferred
             revenue which will be recognized in 1997 as expenses associated
             with the disposition of the contract are incurred.

                  In April 1995, one of the Company's major contracts was
             renegotiated.  Under the terms of the new agreement, the Company
             received $12,000 as prepayment for services to be rendered over
             the four year term of the new agreement.  This prepayment is being
             recognized as contract revenue ratably over the term of the
             contract.

                  The Company is obligated under certain operating leases for
             its pro rata share of the lessors' operating expenses.  Rent
             expense was $18,212, $23,731 and $41,927 for 1996, 1995 and 1994,
             respectively.

      Letters of credit

                  The Company had $1,217 in irrevocable letters of credit as of
             December 31, 1996.  The letters of credit were issued in
             conjunction with the provisions of certain contracts.  The fair
             value of these letters of credit is estimated to be equal to the
             face values of the letters of credit, based on the nature of the
             fee arrangements with the issuing banks.

      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 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 ($67,716 and $82,686 as of December 31, 1996 and
             1995, 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 $852 and $1,008 for the years ended December 31,
             1996 and 1995, 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 $1,877 benefit as of
             December 31, 1996.  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, 1996, the Company had one forward exchange
             contract maturing in January 1997.  This British pounds to U.S.
             dollar trade totaled $4,551 as of December 31, 1996.

                                 ----------



                  The estimated fair value of the Company's forward exchange
             contract using bank or market quotes and the year end foreign
             exchange rates was a net liability of $117 as of December 31,
             1996.  The Company's remaining risk associated with this
             transaction is the risk of default by the bank, which the Company
             believes to be remote.

      Contingent put rights

                  Under the terms of various stock agreements, a total of
             2,905,372 shares of Class A Common Stock are subject to contingent
             put rights.  For 2,000,000 and 325,372 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
             580,000 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 flows.

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, 1996, 1995 and 1994 amounted to $4,785, $1,919 and $1,680,
      respectively.  The Company's contribution of common stock for the years
      ended December 31, 1996, 1995 and 1994 totaled 6,325, 99,486, and 70,134
      shares, respectively, which were allocated to participants' plan accounts
      using a formula based on compensation.  Compensation expense of $14, $224
      and $123, 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 as a result of this
      grant.

           In 1996, the company contributed 162,143 shares to several trusts
      established for the benefit of employees transitioning to the company
      pursuant to certain contracts.  Compensation expense of $405 was recorded
      related to these grants.

      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 June 30, 1998 or the maturity
      date of the individual loans, the Company will purchase, at the bank's
      option, any of these loans.  As of December 31, 1996, approximately $809
      remain outstanding under these loans.  All of these loans bear interest
      at a rate of 9.50% and are due at various dates between July 1, 1998 and
      February 26, 2000.

           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

      is publicly traded.  In April 1997, the Company committed to loan up to
      an additional $2,500 to this officer.  For these additional loans, up to
      $1,500 will be collateralized by Class A Common Shares held by this
      officer and up to $1,000 will be collateralized by a mortgage on the
      officer's residence.  These additional loans will bear interest at the
      greater of 7.25% or the applicable federal rate.

           The Company has 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 has paid a license fee of $1,000 directly to PII in
      connection with the license.  The Company has a separate contract with
      Witan to perform development work on the licensed software.  PII is an
      affiliate of a stockholder of the Company.

17.   Subsequent Event (Unaudited)

      Swiss Bank

           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 are 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 Common Stock, (iv) the sale to Swiss Bank of shares of
      the Company's Class B Common Stock, and (v) the termination of all
      options to acquire shares of the Company's Class B Common 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.  The portion that
      would be returned to Swiss Bank upon such a termination declines 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 Common Stock at a cash non-refundable purchase price of $2.25 per
      option. These shares of the Company's Class B Common Stock 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 the underlying 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 Common Stock,
      subject to the same transferability and holding-period restrictions, at a
      purchase price of $7.30 per share. These options and shares were sold in
      connection with the execution and delivery of the 10 year SBC Warburg EPI
      Agreement.  Both the 50,000 shares of Class B Common Stock and the
      3,617,160 shares of Class B Common Stock subject to options vest at a
      rate, in the aggregate, of 31,953 shares per month for the first five
      years of the agreement, and at a rate of 29,167 shares per month
      thereafter.  In the event of termination of the 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 shares of the Company's Class B Common
      Stock, 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 have the right 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 stockholder's 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 shares of Class B Common
      Stock, 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 shares of Class A Common Stock 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 shares of Class B Common Stock 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.

                              AMENDED AND RESTATED
                          CERTIFICATE OF INCORPORATION
                                       OF
                           PEROT SYSTEMS CORPORATION

         Perot Systems Corporation, a corporation organized and existing under
the laws of the State of Delaware, hereby certifies as follows:

         1.      The name of the Corporation is Perot Systems Corporation.
Perot Systems Corporation was originally incorporated under the same name, and
the Certificate of Incorporation of the Corporation was filed with the
Secretary of State of the State of Delaware on December 19, 1995.

         2.      Pursuant to Sections 242 and 245 of the General Corporation
Law of the State of Delaware, this Restated Certificate of Incorporation
restates and integrates and further amends the provisions of the Certificate of
Incorporation of this Corporation.

         3.      The text of the Restated Certificate of Incorporation as
heretofore amended or supplemented is hereby restated and further amended to
read in its entirety as follows:

                                   ARTICLE I

         The name of the Corporation is Perot Systems Corporation.

                                   ARTICLE II

         The name of the Corporation's registered agent and the address of its
registered office in the State of Delaware is The Corporation Trust Company,
1209 Orange Street, Wilmington, New Castle County, Delaware 19805.

                                  ARTICLE III

         The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of the State of Delaware.

                                   ARTICLE IV

         A.      The aggregate number of shares of capital stock which the
Corporation shall have authority to issue is 124,000,000 shares, consisting of:

                 (i)      100,000,000 shares of Class A Common Stock, par 
         value $0.01 per share;

         and

                 (ii)     24,000,000 shares of Class B Common Stock, par value
         $0.01 per share.



                                     Page 1
<PAGE>   2
         B.      Shares of Class B Common Stock will have no voting rights,
except to the extent that the Delaware General Corporation Law requires a vote
of the Class B Common Stock with respect to an amendment to the Certificate of
Incorporation that would increase or decrease the par value of the Class B
Common Stock or alter or change the powers, preferences or special rights of
shares of Class B Common Stock so as to affect them materially and adversely.
No authorization or issuance of any capital stock of the Corporation will be
considered to alter or change the powers, preferences or special rights of
shares of Class B Common Stock.  The number of authorized shares of Class B
Common Stock may be increased or decreased (but not below the number of shares
of Class B Common Stock then outstanding or reserved for issuance pursuant to
outstanding options, warrants or similar rights) by the affirmative vote of the
holders of a majority of the voting stock of the Corporation, voting as a
single class, without any vote by holders of the Class B Common Stock.

         Any amendment to the Certificate of Incorporation, merger or
consolidation, sale, lease or exchange of all or substantially all of the
Corporation's property and assets or voluntary dissolution of the Corporation
that (in any such case) requires approval by the Corporation's stockholders
under Delaware law must be approved by the affirmative vote of the holders of
at least 66-2/3% of the outstanding stock of the Corporation entitled to vote
thereon, and at least 66- 2/3% of the outstanding stock of each class entitled
to vote thereon as a class.

1.       Conversion of Class B Common Stock.

         (a)     Each share of Class B Common Stock shall be convertible, on a
share for share basis, at the option of the holder thereof, into a fully paid
and nonassessable share of Class A Common Stock upon satisfaction of the terms
of Section 1(b) below for the purpose of the transfer, sale or other
disposition thereof (a "sale") to a third party purchaser that is not an
"affiliate" (as defined in Rule 144(a)(1) under the Securities Act of 1933, as
amended) of the holder thereof (a "Third Party") if such sale is made (a) in a
widely dispersed public offering of the Class A Common Stock; (b) to a Third
Party that, prior to such sale, controls more than 50% of the then outstanding
voting securities (as defined in the Bank Holding Company Act of 1956, as
amended, or in Regulation Y of the Board of Governors of the Federal Reserve
System) of the Corporation; (c) to a Third Party that, after such sale, is the
beneficial owner (directly or indirectly) of not more than two percent (2%) of
the outstanding voting stock of the Corporation having power to elect
directors; (d) in a transaction that complies with Rule 144 (or any successor
thereto) under the Securities Act of 1933, as amended; or (e) by Swiss Bank
Corporation or its affiliates in a transaction approved in advance by the Board
of Governors of the Federal Reserve System as being in compliance with the
requirements of the Bank Holding Company Act of 1956, as amended, and any rules
and regulations or interpretations promulgated by the Board of Governors of the
Federal Reserve System pursuant thereto (each, a "Qualifying Sale").

         (b)     The conversion of Class B Common Stock into Class A Common
Stock for the purpose of making a Qualifying Sale will be effective only after
receipt by the Corporation of a certificate, executed by the holder of the
Class B Common Stock that is the subject of the sale, stating that the proposed
sale is a Qualifying Sale.





                                   Page 2

<PAGE>   3
         (c)     As promptly as practicable after receipt by the Corporation of
the certificate referred to in Section 1(b) and delivery to the Corporation of
the certificate or certificates evidencing any shares so converted, duly
endorsed for transfer, the Corporation shall issue and deliver to the Third
Party (or, if necessary for purposes of effecting the Qualifying Sale, to the
holder of the shares to be converted) a certificate or certificates for the
number of shares of Class A Common Stock that are the subject of the Qualifying
Sale.  If only a portion of the shares of Class B Common Stock represented by a
certificate are transferred in a Qualifying Sale, the Corporation shall issue
and deliver to the holder of such Class B Common Stock a new certificate
representing the Class B Common Stock retained by such holder.

         (d)     The Corporation shall at all times reserve and keep available,
out of its authorized but unissued Class A Common Stock, solely for the purpose
of effecting the conversion of the Class B Common Stock, the number of shares
of Class A Common Stock deliverable upon the conversion of all Class B Common
Stock from time to time outstanding.  The Corporation shall from time to time
(subject to obtaining necessary director and stockholder action), in accordance
with the laws of the State of Delaware, increase the authorized amount of its
Class A Common Stock if at any time the authorized number of shares of its
Class A Common Stock remaining unissued shall not be sufficient to permit the
conversion of all of the shares of Class B Common Stock at the time
outstanding.

                                   ARTICLE V

         In furtherance and not limitation of the powers conferred by the laws
of the State of Delaware, the Board of Directors is expressly authorized to
alter, amend or repeal the bylaws of the Corporation or to adopt new bylaws.

                                   ARTICLE VI

         A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the director derived
any improper personal benefit.  If the Delaware General Corporation Law is
amended after the filing of this Certificate of Incorporation to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of a director of the Corporation shall be
eliminated or limited to the fullest extent permitted by the Delaware General
Corporation Law, as so amended.

         Any repeal or modification of the foregoing paragraph by the
stockholders of the Corporation shall not adversely affect any right or
protection of a director of the Corporation existing at the time of such repeal
or modification.

                                  ARTICLE VII

         A.      Right to Indemnification.  Each person who was or is made a
party or is threatened to be made a party to or is otherwise involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that he or
she, or a person of whom he or she is the legal representative, is or was a
director or officer of the Corporation or is or was serving at the request of
the Corporation as a director or officer of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a
director or officer or in any other capacity while serving as a director or
officer, shall be indemnified and held harmless by the Corporation to the
fullest extent authorized by the Delaware General Corporation Law, as the same
exists or may hereafter be amended (but, in the case of any such amendment,
only to the  extent that such amendment permits the Corporation to provide
broader indemnification rights than permitted prior thereto), against all
expense, liability and loss (including, without limitation, attorneys' fees,
judgments, fines, excise taxes or penalties and amounts paid or to be paid in
settlement) incurred or suffered by such indemnitee in connection therewith and
such indemnification shall continue with respect to an indemnitee who has
ceased to be a director or officer and shall inure to the benefit of the
indemnitee's heirs, executors and administrators; provided, however, that,
except as provided in paragraph (B) hereof with respect to proceedings to
enforce rights to indemnification, the Corporation shall indemnify any such
indemnitee in connection with a proceeding initiated by such indemnitee only if
such proceeding was authorized by the Board of Directors of the Corporation.
The right to indemnification conferred in this Article VII shall be a contract
right and shall include the right to be paid by the Corporation the expenses
incurred in defending any such proceeding in advance of its final disposition
(hereinafter an "advancement of expenses"); provided, however, that, if the
Delaware General Corporation Law requires, an advancement of expenses incurred
by an indemnitee shall be made only upon delivery to the Corporation of an
undertaking (hereinafter an "undertaking"), by or on behalf of such indemnitee,
to repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is no further right to appeal (hereinafter a
"final adjudication") that such indemnitee is not entitled to be indemnified
for such expenses under this Article VII or otherwise.

         B.      Right of Indemnitee to Bring Suit.  If a claim under paragraph
(A) of this Article VII is not paid in full by the Corporation within sixty
days after a written claim has been received by the Corporation (except in the
case of a claim for an advancement of expenses, in which case the applicable
period shall be twenty days), the indemnitee may at any time thereafter bring
suit against the Corporation to recover the unpaid amount of the claim.  If
successful in whole or in part in any such suit, the indemnitee shall also be
entitled to be paid the expense of prosecuting or defending such suit.  In (i)
any suit brought by the indemnitee to enforce a right to indemnification
hereunder (but not in a suit brought by the indemnitee to enforce a right to an
advancement of expenses) it shall be a defense that, and (ii) in any suit by
the Corporation to recover an advancement of expenses pursuant  to the terms of
an undertaking, the Corporation shall be entitled to recover such expenses upon
a final adjudication that, the indemnitee has not met the applicable standard
of conduct set forth in the Delaware General Corporation Law.

Neither the failure of the Corporation (including its Board of Directors,
independent legal counsel or its stockholders) to have made a determination
prior to the commencement of such suit that indemnification of the indemnitee
is proper in the circumstances because the indemnitee has met the applicable
standard of conduct set forth in the Delaware General Corporation Law, nor an
actual determination by the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) that the indemnitee has not met
such applicable standard of conduct, shall create a presumption that the
indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the indemnitee, be a defense to such suit.  In any suit
brought by the indemnitee to enforce a right to indemnification or to an
advancement of expenses hereunder or by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the burden of
proving that the indemnitee is not entitled under this Article VII or otherwise
to be indemnified, or to such advancement of expenses, shall be on the
Corporation.

         C.      Non-Exclusivity of Rights.  The rights to indemnification and
to the advancement of expenses conferred in this Article VII shall not be
exclusive of any other right which any person may have or hereafter acquire
under this Certificate of Incorporation or any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.

         D.      Insurance.  The Corporation may maintain insurance, at its
expense, to protect itself and any indemnitee against any expense, liability or
loss, whether or not the Corporation would have the power to indemnify such
person against such expense, liability or loss under the Delaware General
Corporation Law.

         E.      Indemnity of Employees and Agents of the Corporation.  The
Corporation may, to the extent authorized from time to time by the Board of
Directors, grant rights to indemnification and to the advancement of expenses
to any employee or agent of the Corporation to the fullest extent of the
provisions of this Article VII or as otherwise permitted under the Delaware
General Corporation Law with respect to the indemnification and advancement of
expenses of directors and officers of the Corporation.

         IN WITNESS WHEREOF, this Restated Certificate of Incorporation has
been signed by Peter A. Altabef, its authorized officer this 25th day of April,
1997.

required, in which case such express provision shall govern and control the
decision of such question.

         Section 10.  Proxies.  (a)  Each stockholder entitled to vote at a
meeting of stockholders or to express consent or dissent to corporate action in
writing without a meeting may authorize




                                   Page 2
<PAGE>   3
another person or persons to act for him by proxy, but no such proxy shall be
voted or acted upon after three years from its date, unless the proxy provides
for a longer period.

                 (b)      Without limiting the manner in which a stockholder
may authorize another person or persons to act for him as proxy pursuant to
subsection (a) of this Section 10, the following shall constitute a valid means
by which a stockholder may grant such authority:

                          (i)     A stockholder may execute a writing
         authorizing another person or persons to act for him as proxy.
         Execution may be accomplished by the stockholder or his or its
         authorized officer, director, employee or agent signing such writing
         or causing his or her signature to be affixed to such writing by any
         reasonable means including, but not limited to, by facsimile
         signature.

                          (ii)    A stockholder may authorize another person or
         persons to act for him as proxy by transmitting or authorizing the
         transmission of a telegram, cablegram, or other means of electronic
         transmission to the person who will be the holder of the proxy or to a
         proxy solicitation firm, proxy support service organization or like
         agent duly authorized by the person who will be the holder of the
         proxy to receive such transmission, provided that any such telegram,
         cablegram or other means of electronic transmission must either set
         forth or be submitted with information from which it can be determined
         that the telegram, cablegram or other electronic transmission was
         authorized by the stockholder.  If it is determined that such
         telegrams, cablegrams or other electronic transmissions are valid, the
         inspectors or, if there are no inspectors, such other persons making
         that determination shall specify the information upon which they
         relied.

                 (c)      Any copy, facsimile telecommunication or other
reliable reproduction of the writing or transmission created pursuant to
subsection (b) of this Section 10 may be substituted or used in lieu of the
original writing or transmission for any and all purposes for which the
original writing or transmission could be used, provided that such copy,
facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.

                 (d)      Any copy, facsimile telecommunication or other
reliable reproduction of the writing or transmission created pursuant to
subsection (b) of this Section 10 may be substituted or used in lieu of the
original writing or transmission for any and all purposes for which the
original writing or transmission could be used, provided that such copy,
facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.

         Section 11.  Voting.  Unless otherwise provided by statute or the
certificate of incorporation, each stockholder shall have one vote for each
share of stock having voting power, registered in his name on the books of the
corporation.

         Section 12.  Consent of Stockholders in Lieu of Meeting.  Any action
required to be taken at any annual or special meeting of stockholders, or any
action which may be taken at any annual




                                   Page 3
<PAGE>   4
or special meeting of stockholders, may be taken without a meeting, without
prior notice and without a vote, if a consent or consents in writing, setting
forth the action so taken, shall be signed by the holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted and such consent or consents are delivered to
the corporation. Every written consent shall bear the date of signatures of
each stockholder and no written consent shall be effective to take the
corporate action referred to therein unless, within sixty days of the earliest
dated consent, written consents signed by a sufficient number of holders to
take action are delivered to the corporation.  Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

         Section 13.  Inspectors.  (a) The corporation may, in advance of any
meeting of stockholders, appoint one or more inspectors to act at the meeting
and make a written report thereof.  The corporation may designate one or more
persons as alternate inspectors to replace any inspector who fails to act.  If
no inspector or alternate is able to act at a meeting of stockholders, the
chairman of the meeting shall appoint one or more inspectors to act at the
meeting.  Each inspector, before entering upon the discharge of his duties,
shall take and sign an oath faithfully to execute the duties of inspector with
strict impartiality and according to the best of his ability.

                 (b)      The inspectors shall (i) ascertain the number of
shares outstanding and the voting power of each, (ii) determine the shares
represented at a meeting and the validity of proxies and ballots, (iii) count
all votes and ballots, (iv) determine and retain for a reasonable period a
record of the disposition of any challenges made to any determination by the
inspectors, and (v) certify their determination of the number of shares
represented at the meeting, and their count of all votes and ballots.  The
inspectors may appoint or retain other persons or entities to assist the
inspectors in the performance of the duties of the inspectors.

                 (c)      The date and time of the opening and the closing of
the polls for each matter upon which the stockholders will vote at a meeting
shall be announced at the meeting.  No ballot, proxies or votes, nor any
revocations thereof or changes thereto, shall be accepted by the inspectors
after the closing of the polls unless the Delaware Court of Chancery, upon
application by a stockholder, shall determine otherwise.

                 (d)      In determining the validity and counting of proxies
and ballots, the inspectors shall be limited to an examination of the proxies,
any envelopes submitted with those proxies, any information provided in
accordance with Article II, Section 10(b)(ii), ballots and the regular books
and records of the corporation, except that the inspectors may consider other
reliable information for the limited purpose of reconciling proxies and ballots
submitted by or on behalf of banks, brokers, their nominees or similar persons
that represent more votes than the holder of a proxy is authorized by the
record owner to cast, or more votes than the stockholder holds of record.  If
the inspectors consider other reliable information for the limited purpose
permitted herein, the inspectors at the time they make their certification
pursuant to subsection (b)(v) of this Section shall specify the precise
information considered by them including the





                                   Page 4
<PAGE>   5
person or persons from whom they obtained the information, when the information
was obtained, the means by which the information was obtained and the basis for
the inspector's belief that such information is accurate and reliable.

                                   ARTICLE IX

                            SHARES AND STOCKHOLDERS

         Section 1.  Certificates Representing Shares.  Every holder of stock
in the corporation shall be entitled to have a certificate, signed by, or in
the name of the corporation by, the Chairman or Vice Chairman of the Board of
Directors, or the President or a Vice President and the Treasurer or an
Assistant Treasurer or the Secretary or an Assistant Secretary of the
corporation, certifying the number of shares owned by him in the corporation.
The signature of any such officer may be facsimile.  In case any officer who
has signed or whose facsimile signature has been placed upon such certificate
shall have ceased to be such officer before such certificate is issued, it may
be issued by the corporation with the same effect as if he were such officer at
the date of its issuance. If the corporation shall be authorized to issue more
than one class of stock or more than one series of any class, the powers,
designations, preferences and relative, participating, optional or other
special rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights shall be set
forth in full or summarized on the face or back of the certificate which the
corporation shall issue to represent such class or series of stock, provided
that, except as otherwise provided in Section 202 of the General corporation
Law of the State of Delaware, in lieu of the foregoing requirements, there may
be set forth on the face or back of  the certificate which the corporation
shall issue to represent such class or series of stock a statement that the
corporation will furnish without charge to each stockholder who so requests the
designations, preferences and relative, participating, optional or other
special rights of each class or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

         Section 2.  Transfer of Shares.  Subject to valid transfer
restrictions and to stop-transfer orders directed in good faith by the
corporation to any transfer agent to prevent possible violations of federal or
state securities laws, rules or regulations, or for any other lawful purpose,
upon surrender to the corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

         Section 3.  Fixing Record Date.

         (a)     In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, the Board of Directors may fix a record date, which record
date shall not precede the date upon which the resolution fixing the record
date is adopted by the Board of Directors, and which record date shall not be
more than sixty nor less than ten days before the date of such meeting.  If no
record date is fixed by the Board of Directors, the record date for determining
stockholders entitled to notice of or to vote at a meeting of stockholders
shall be at the close of business on the day next preceding the date on which
notice is given, or, if notice is waived, at the close of business on the date
next preceding the day on which the meeting is held.  A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned
meeting.

         (b)     In order that the corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors may fix a record date, which record date shall not precede the
date upon which the resolution fixing the record date is adopted by the Board
of Directors, and which date shall not be more than ten days after the date
upon which the resolution fixing the record date is adopted by the Board of
Directors.  If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate
action in writing without a meeting, when no prior action by the Board of
Directors is required by this Section, shall be the first date on which a
signed written consent setting forth the action taken or proposed to be taken
is delivered to the corporation by delivery to its registered office in the
State of Delaware, its principal place of business, or an officer or agent of
the corporation having custody of the book in which proceedings of meetings of
stockholders are recorded.  Delivery made to the corporation's registered
office shall be by hand or by certified or registered mail, return receipt
requested.  If no record date has been fixed by the Board of Directors and
prior action by the Board of Directors is required by statute, the record date
for determining stockholders entitled to consent to corporate action in writing
without a meeting shall be at the close of business on the day on which the
Board of Directors adopts the resolution taking such prior action.

         (c)     In order that the corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to receive any rights in respect of
any change, conversion or exchange of stock, or for  the purpose of any other
lawful action, the Board of Directors may fix a record date, which record date
shall not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than sixty days prior to such
action.  If no record date is fixed, the record date for determining
stockholders for any such purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating thereto.

         Section 4.  Registered Stockholders.  The corporation shall be
entitled to recognize the exclusive right of a person registered on its books
as the owner of any share or shares to receive dividends, and to vote as such
owner, and for all other purposes as such owner; and the





                                   Page 11
<PAGE>   12
corporation shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or
not it shall have express or other notice thereof, except as otherwise provided
by the laws of the State of Delaware.

         Section 5.  Lost Certificates.  The Board of Directors may direct a
new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed.  When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require and/or give the corporation a bond in such sum as it may
direct as indemnity against any claim that may be made against the corporation
with respect to the certificate alleged to have been lost, stolen or destroyed.


                                   ARTICLE X

                                INDEMNIFICATION

         (a)     Each person who was or is made a party or is threatened to be
made a party to or is otherwise involved in any action, suit or proceeding,
whether civil, criminal, administrative or investigative (hereinafter a
"proceeding"), by reason of the fact that he or she, or a person of whom he or
she is the legal representative, is or was a director or officer of the
corporation or is or was serving at the request of the corporation as a
director or officer of another corporation or of a partnership, joint venture,
trust or other enterprise, including service with respect to an employee
benefit plan (hereinafter an "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as a director or officer
or in any other capacity while serving as a director or officer, shall be
indemnified and held harmless by the corporation to the fullest extent
authorized by the Delaware General corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the corporation to provide broader
indemnification rights than permitted prior thereto), against all expense,
liability and loss (including, without limitation, attorneys' fees, judgments,
fines, excise taxes or penalties and amounts paid or to be paid in settlement)
incurred or suffered by such indemnitee in connection therewith and such
indemnification shall continue with respect to an indemnitee who has ceased to
be a director or officer and shall inure to the benefit of the indemnitee's
heirs, executors and administrators; provided, however, that, except as
provided in paragraph (b) of this Article X with respect to proceedings to
enforce rights to indemnification, the corporation shall indemnify any such
indemnitee in connection with a proceeding initiated by such indemnitee only if
such proceeding was authorized by the Board of Directors of the corporation.
The right to indemnification conferred in this Article X shall be a contract
right and shall include the right to be paid by the corporation the expenses
incurred in defending any such proceeding in advance of its final disposition
(hereinafter an "advancement of expenses"); provided, however, that, if the
Delaware General corporation Law requires, an advancement of expenses incurred
by an indemnitee shall be made only upon delivery to the corporation of an
undertaking (hereinafter an





                                   Page 12
<PAGE>   13
"undertaking"), by or on behalf of such indemnitee, to repay all amounts so
advanced if it shall ultimately be determined by final judicial decision from
which there is no further right to appeal (hereinafter a "final adjudication")
that such indemnitee is not entitled to be indemnified for such expenses under
this Article  X or otherwise.

         (b)     If a claim under paragraph (a) of this Article X is not paid
in full by the corporation within sixty days after a written claim has been
received by the corporation (except in the case of a claim for an advancement
of expenses, in which case the applicable period shall be twenty days), the
indemnitee may at any time thereafter bring suit against the corporation to
recover the unpaid amount of the claim.  If successful in whole or in part in
any such suit, the indemnitee shall also be entitled to be paid the expense of
prosecuting or defending such suit.  In (i) any suit brought by the indemnitee
to enforce a right to indemnification hereunder (but not in a suit brought by
the indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (ii) in any suit by the corporation to recover an advancement
of expenses pursuant  to the terms of an undertaking, the corporation shall be
entitled to recover such expenses upon a final adjudication that, the
indemnitee has not met the applicable standard of conduct set forth in the
Delaware General corporation Law.  Neither the failure of the corporation
(including its Board of Directors, independent legal counsel or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General corporation Law, nor an actual determination by the
corporation (including its Board of Directors, independent legal counsel, or
its stockholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit.  In any suit brought by the indemnitee
to enforce a right to indemnification or to an advancement of expenses
hereunder or by the corporation to recover an advancement of expenses pursuant
to the terms of an undertaking, the burden of proving that the indemnitee is
not entitled under this Article X or otherwise to be indemnified, or to such
advancement of expenses, shall be on the corporation.

         (c)     The rights to indemnification and to the advancement of
expenses conferred in this Article X shall not be exclusive of any other right
which any person may have or hereafter acquire under the certificate of
incorporation or any bylaw of the corporation, agreement, vote of stockholders
or disinterested directors or otherwise.

         (d)     The corporation may maintain insurance, at its expense, to
protect itself and any indemnitee against any expense, liability or loss,
whether or not the corporation would have the power to indemnify such person
against such expense, liability or loss under the Delaware General corporation
Law.

         (e)     The corporation may, to the extent authorized from time to
time by the Board of Directors, grant rights to indemnification and to the
advancement of expenses to any employee or agent of the corporation to the
fullest extent of the provisions of this Article X or as otherwise permitted
under the Delaware General corporation Law with respect to the indemnification
and advancement of expenses of directors and officers of the corporation.

         Section 6.  Fiscal Year.  The fiscal year of the corporation shall be
fixed by the Board of Directors; if not so fixed, it shall be the calendar
year.

                           PEROT SYSTEMS CORPORATION
                             1991 STOCK OPTION PLAN



         This Stock Option Plan, as amended, of Perot Systems Corporation is
for the purpose of attracting and retaining outstanding employees of Perot
Systems and any of its majority-owned subsidiaries and providing them with a
strong incentive to contribute to the success of the Company by granting them
options to acquire shares of Common Stock, $0.01 par value, of Perot Systems in
accordance with the provisions of the Plan, as set forth below.

         Certain capitalized terms used in this Plan are defined at the end of
the Plan.  Other terms used in the Plan are defined in the text as they occur
and have the meanings there indicated.

1.       Term and Amendments.

         The Plan is effective when approved by the Board of Directors of Perot
Systems.  Either the Board of Directors or the shareholders may amend or
terminate the Plan in their sole discretion.  Neither the Board of Directors
nor the shareholders, however, may amend or terminate the Plan in a way that
adversely affects any rights relating to stock options granted under the Plan
before the amendment or termination without the consent of the person whose
rights are adversely affected.

2.       Administration.

         The Board of Directors is required to appoint a Committee of at least
three members of the Board of Directors which will be responsible for
administering and interpreting the Plan.  The Committee may from time to time
adopt, amend, waive, and rescind such procedures for the administration of the
Plan as it deems advisable, consistent with the provisions of the Plan.  To the
extent permitted by law, any determination made by the Committee in
administering or interpreting the Plan is conclusive.

3.       Available Shares.

         The Board of Directors shall reserve for issuance not more than six
million shares of Common Stock to be available for issue pursuant to stock
options granted under the Plan.  The Board will take steps to assure that
offerings and sales of securities under the Plan qualify under Rule 701 under
the Securities Act of 1933, including Rule 701's limit on the amount of
securities that can be offered and sold.  Shares made available upon the
exercise of stock options granted under the Plan may be either treasury shares
or
<PAGE>   2
authorized but unissued shares or a combination of the two.  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, as appropriate, 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 in the
Plan.

4.       Participants; Stock Option Agreements.

         The Committee shall select the employees of the Company who will be
granted stock options under the Plan and shall determine the terms of the stock
options to be granted to each selected employee, including (i) the number of
shares of Common Stock to be covered by each option; (ii) the purchase price
per share of the Common Stock (consistent with applicable law) covered by each
option, which must be at least equal to the fair market value of the Common
Stock at the time of the grant; (iii) the term of each option, which may not
exceed 11 years; (iv) the vesting schedule for each option; (v) any holding
period or other restriction applicable to shares of Common Stock purchased
pursuant to each option; and (vi) any other terms deemed  appropriate by the
Committee.  Each such employee may elect to become a Participant in the Plan by
entering into a Stock Option Agreement approved by the Committee.  The
Committee and the Participant may thereafter amend, modify, or waive the
provisions of the Stock Option Agreement by mutual written agreement.  The
Stock Option Agreement will contain provisions to reflect and enforce the
applicable provisions of the Plan and any other provisions deemed appropriate
by the Committee, including the following:

                 (a)      Payment of Purchase Price Upon Exercise.

                 Each Stock Option Agreement will provide that the purchase
         price of the shares as to which an option is exercised must be paid to
         Perot Systems at the time of 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.  Other
         consideration may include shares of Common Stock already held by a
         Participant or Common Stock withheld upon the exercise of the option,
         which will be accepted at Market Value.




                                      2
<PAGE>   3
                 (b)      Investment Representation.

                 Each Stock Option Agreement will provide that, upon demand by
         the Committee, any person exercising a stock option under the Plan may
         be required to deliver to the Committee, at the time of any exercise
         of the option, a written representation that the shares acquired upon
         the exercise are being acquired for investment and not for resale or
         with a view to distribution.

5.       Payment of Taxes with Common Stock.

         If the Common Stock is not Publicly Traded within five years of the
effective date of the Plan, the Committee may elect to assist Participants in
satisfying an obligation to pay or withhold taxes required as a result of the
exercise of an option by accepting shares of Common Stock at Market Value to
satisfy the tax obligation.  The shares of Common Stock accepted may be either
shares withheld upon the exercise of an option or other shares already owned by
the Participant.  In determining whether to approve acceptance of shares of
Common Stock to satisfy a tax obligation, the Committee may consider whether
the shares proposed to be accepted are subject to any holding period or other
restrictions on transfer and may waive or arrange for the waiver of any such
restrictions.

6.       Restrictions and Conditions Applicable to Stock Options and Purchased
         Stock.

         All stock options granted to a Participant pursuant to a Stock Option
Agreement and shares of Purchased Stock shall, except as otherwise provided in
the Stock Option Agreement, be subject to the following restrictions and
conditions:

                 (a)      Non-transferability of Options.

                 No option granted under the Plan may be sold or otherwise
         transferred other than by will or by the laws of descent and
         distribution upon the Participant's death.  During the lifetime of the
         Participant, the option is exercisable only by the Participant.

                 (b)      Restricted Stock.

                 Unless Perot Systems otherwise agrees in writing, shares of
         Purchased Stock may not be sold or otherwise transferred, other than
         by will or under the laws of descent and distribution upon the
         Participant's death, until and unless (i) any holding period or other
         restriction on such a sale or other transfer specified in the Stock
         Option Agreement has expired, and (ii) Perot Systems has waived in
         writing any option to buy back such shares that it may have under the
         Stock Option Agreement.




                                      3
<PAGE>   4
                 (c)      Buyback of Purchased Stock and Payback of Certain
         Profits.

                 Perot Systems will have the right to buy back from a
         Participant any Purchased Stock then owned by the Participant and the
         right to require a Participant to pay back to Perot Systems the amount
         of the Participant's Net Investment Proceeds with respect to shares of
         Purchased Stock that have been sold or otherwise transferred by the
         Participant in the circumstances and on the terms and conditions
         specified in the Participant's Stock Option Agreement.

7.       Valuation.

         The Board of Directors will determine the Market Value of shares of
Purchased Stock as of each Valuation Date.

8.       Stock Certificates; Rights as Shareholder.

         A Stock Option Agreement may provide that Perot Systems will retain
for safekeeping all certificates representing shares of Purchased Stock issued
under the agreement.  Each such certificate may bear such legends as the
Committee determines are necessary or appropriate.  Whether or not certificates
representing such shares have been issued or delivered, each Participant upon
purchasing such shares will have all the rights of a shareholder of Common
Stock, including voting, dividend, and distribution rights, with respect to all
shares of Purchased Stock owned by the Participant, except as may otherwise be
provided in the Participant's Stock Option Agreement.  No Participant will have
any rights as a shareholder with respect to any shares of Common Stock subject
to options granted under the Plan before the date of issuance to the
Participant of shares upon the exercise of such options.

9.       Compliance with Laws and Regulations.

         The Plan, the grant and exercise of options under the Plan, and the
obligation of Perot Systems to sell and deliver shares under such options, are
subject to all applicable federal and state laws, rules, and regulations and to
such approvals by any government or regulatory agency as may be required.
Perot Systems is permitted a reasonable delay in issuing any shares of Common

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

                 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.

                 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 for six months after the Purchased Stock (or stock
                 of the same class as the Purchased Stock) is Publicly Traded.

         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 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





                                       4
<PAGE>   5

                 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 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:





                                       5
<PAGE>   6
         (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, 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





                                       6
<PAGE>   7
         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,
         property 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
         written consent of Perot Systems.

13.      Attorneys' Fees.  If any legal proceeding is brought 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.

14.      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.

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

16.      Governing Law.  This Agreement shall be governed by and construed in
         accordance with the law of the State of Texas, without regard to the
         choice of law rules in such law.

17.      Entire Agreement.  This Agreement, together with the Plan and any
         procedure adopted by the Committee thereunder, constitutes the entire
         agreement between the parties with respect to its subject matter and

                           PEROT SYSTEMS CORPORATION
                             RESTRICTED STOCK PLAN



         This Restricted Stock Plan, as amended, (the "Plan") of Perot Systems
Corporation ("Perot Systems") is for the purpose of attracting and retaining
outstanding employees of Perot Systems and its subsidiaries, if any,
(collectively, the "Company") and providing them with a strong incentive to
contribute to the success of the Company by giving them the opportunity to
acquire shares of Common Stock, $0.01 par value, of Perot Systems ("Common
Stock") in accordance with the provisions of the Plan, as set forth below.

1.       Term.

         The Plan shall be effective upon its approval by the Board of
Directors of Perot Systems (the "Board of Directors") and may thereafter be
amended or terminated by the Board of Directors in its discretion.  No such
amendment or termination of the Plan shall adversely affect or alter any rights
or restrictions relating to shares of Common Stock issued pursuant to the Plan
("Restricted Stock") prior to such amendment or termination.

2.       Restricted Stock Plan Committee.

         The Board of Directors shall appoint a Restricted Stock Plan Committee
(the "Committee"), which shall be responsible for administering and
interpreting the Plan.  The Committee may from time to time adopt, amend, waive
and rescind such procedures for the administration of the Plan, consistent with
the provisions hereof, as the Committee deems advisable.  To the extent
permitted by law, any determination made by the Committee in administering or
interpreting the Plan shall be conclusive.

3.       Available Shares.

         The number of shares of Common Stock available for issuance pursuant
to the Plan shall be established by the Board of Directors from time to time.
These shares may be either treasury shares or authorized but unissued shares.
The Board of Directors may from time to time increase or reduce the number of
shares of Common Stock available for issuance pursuant to the Plan, but no such
reduction shall affect any shares previously issued pursuant to the Plan.  If
any change is made in the number of shares of Common Stock (such as by stock
dividend, stock split, or stock consolidation), the Committee may make such
adjustments in the number of shares and price per share of Restricted Stock
previously issued pursuant to the Plan as the Committee determines is equitable
to preserve the respective rights of the participants in the Plan.
<PAGE>   2
4.       Participants.

         The Committee shall from time to time select the employees of the
Company who will be offered the opportunity to participate in the Plan and
shall determine the terms of the offer to each selected employee, including (i)
the number of shares of Restricted Stock to be issued to the employee, (ii) the
purchase price per share (consistent with applicable law) to be paid by the
employee, (iii) the vesting schedule upon which such shares will vest to the
employee, and (iv) any other terms deemed appropriate by the Committee.  Each
such employee may elect to become a participant in the Plan (a "Participant")
by entering into an agreement therefor (a "Restricted Stock Agreement") with
Perot Systems, acceptable in form and substance to the Committee, and by paying
to Perot Systems in cash or by check the purchase price for the shares of
Restricted Stock being issued to the employee pursuant to the Restricted Stock
Agreement.  The Restricted Stock Agreement shall contain provisions to reflect
and enforce the applicable provisions of the Plan and any other provisions
deemed appropriate by the Committee.  The committee and the Participant may
thereafter amend, modify, or waive the provisions of the Restricted Stock
Agreement by mutual written agreement.

5.       Restrictions and Conditions Applicable to Restricted Stock.

         All shares of Restricted Stock sold to a Participant pursuant to a
Restricted Stock Agreement shall, except as otherwise provided in the
Restricted Stock Agreement, be subject to the following restrictions and
conditions:

                 (a)      Shares of the Restricted Stock that have not vested
         to the Participant in accordance with the Restricted Stock Agreement
         ("Unvested Stock") may not be sold or otherwise transferred.

                 (b)      Shares of the Restricted Stock that have vested to
         the Participant in accordance with the Restricted Stock Agreement
         ("Vested Stock") may not be sold or otherwise transferred, unless and
         until (i) any restriction on the sale or transfer of such shares
         specified in the Restricted Stock Agreement has expired, and (ii)
         Perot Systems has waived or failed to exercise any option to purchase
         such shares that it may have pursuant to the Restricted Stock
         Agreement.

                 (c)      The Restricted Stock Agreement may contain any other
         restrictions or conditions on the Restricted Stock issued to the
         Participant that the Committee may deem to be advisable.
<PAGE>   3
6.       Stock Certificates.

         If requested by a Participant, Perot Systems will issue and deliver to
the Participant certificates representing any shares of Vested Stock held by
the Participant.  Perot Systems may require that any certificates or other
property representing shares of Unvested Stock remain in the possession of the
Company or an escrow agent designated by the Committee.  Each certificate
representing shares of 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, each
Participant shall have all the rights of a shareholder of Common Stock,
including voting, dividend and distribution rights, with respect to all shares
of Restricted Stock (both Vested Stock and Unvested Stock) held by the
Participant, except as may otherwise be provided in the Participant's
Restricted Stock Agreement.

7.       Severability.

         If any provision of the Plan is held invalid or unenforceable for any
reason, the validity and enforceability of all other provisions of the Plan
shall not be affected thereby.

8.       Governing Law.

         The Plan shall be governed by and construed in accordance with the
laws of the State of Texas, without regard to the choice of law rules in such
law.

represents to Perot Systems that Participant is purchasing these shares for
investment and not with a view to any resale or distribution thereof.

2.    Definitions.  As used in this Agreement, the following terms shall have
      the respective meanings indicated as follows:

      (i)    "Vesting Date" shall mean each date upon which shares of

      Other terms used in this Agreement are defined in the context in which
      they occur and shall have the meanings there indicated.

3.    Restrictions on Transfer.  All shares of Restricted Stock shall be
      subject to the following restrictions on transfer unless the Company
      shall otherwise agree in writing:

      (a)    Shares of Unvested Stock may not be sold or otherwise transferred.

      (b)    Shares of Vested Stock may not be sold or otherwise transferred
             during the Holding Period for those shares.

      (c)    Shares of Vested Stock may not be sold or otherwise transferred
             after the Holding Period for those shares unless and until Perot
             Systems has waived or failed to exercise its option to purchase
             those shares pursuant to Section 4 hereof.

      (d)    Shares of Vested Stock may not be sold or otherwise transferred
             for six months after stock of the same class as the Vested Stock
             is Publicly Traded.

      Perot Systems shall not be obligated to recognize any purported sale or
      other transfer of Restricted 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.  Shares of Vested Stock may,
      however, be sold within the Holding Period to the extent necessary to
      repay the principal of loans secured by Restricted Stock pursuant to a
      security agreement to which Perot Systems is a party, provided that stock
      of the same class as the Vested Stock has been Publicly Traded for six
      months or more.

4.    Options to Purchase Vested Stock.  Unless and until waived by Perot
      Systems and regardless of whether or not Participant is still employed by
      the Company, Perot Systems shall have the following option to purchase
      Vested Stock:





                                       3
<PAGE>   4

             If, after the Holding Period therefor and prior to the date the
             Restricted Stock is Publicly Traded, Participant, or any
             subsequent holder of Vested Stock, desires or is obligated to sell
             or otherwise transfer any shares of Vested Stock (other than a
             transfer to Participant's estate upon Participant's death), the
             holder of such shares shall give Perot Systems written notice of
             the proposed sale or transfer, including the identity of the
             proposed purchaser or transferee, and, for 30 days after receipt
             of such notice, Perot Systems shall have the option, in addition
             to its option under Section 3(d) above to treat any such purported
             sale or transfer as null, void, and of no effect, to purchase for
             cash any or all of such shares at the Market Value thereof.

5.    Manner of Stock Buy Back.  Whenever Perot Systems has a right to buy back
      shares of Restricted Stock, 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 buy back under Section 4 or Section 8, 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 Restricted 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 endorsed
      certificate or stock power 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 within 2
      business days of the tender of the shares.  If the person from whom the
      shares are to be bought back has not complied with an obligation to
      return a certificate and stock power 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.

6.    Termination of Employment.  If Participant's employment with the Company
      is voluntarily or involuntarily terminated during the Vesting Period for
      any reason, then Perot Systems shall be entitled, by notice to
      Participant within 90 days after such termination, to exercise the rights
      specified in Section 8 below, but only as to Unvested Stock.

7.    Competition.  Participant acknowledges that, 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
      customers and potential customers, which training, knowledge and contacts
      would provide invaluable benefits to competitors of the Company.
      Accordingly, and in consideration of Perot Systems' agreement to issue
      Restricted Stock to Participant hereunder, which Participant acknowledges
      is conditioned on the covenants contained herein, Participant agrees that
      Perot Systems shall be entitled to exercise the rights





                                       4
<PAGE>   5
      specified in Section 8 below if Participant, either directly or
      indirectly, whether as an employee, employer, consultant, agent,
      principal, partner, owner, shareholder (other than as a holder of less
      than 5% of a publicly traded class of securities), officer, director, or
      in any other individual or representative capacity, does any of the
      following without the prior written consent of the Company:

      (a)    while Participant is 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 accepts any business or employment from any
                   person or entity that is, or at any time within the
                   preceding two years was or was solicited to become, a
                   customer of the Company if Participant solicited business
                   from or performed services for that customer or prospect
                   while employed by the Company; or

             (iii) recruits, hires, or helps anyone to recruit or hire anyone
                   who is, or at any time within the preceding six months was,
                   an employee of the Company or of any of its customers for
                   whom Participant performed services or from whom Participant
                   solicited business; or

      (b)    discloses to any unauthorized person or entity, or uses, licenses,
             sells, conveys or otherwise exploits in competition with the
             Company or otherwise for the benefit of any person or entity other
             than the Company, any information proprietary to, used by, or in
             the possession of the Company or any of its customers and not
             generally known in the industry which is disclosed to or learned
             by Participant while employed by the Company or thereafter,
             whether or not reduced to writing and whether or not conceived,
             originated, discovered or developed in whole or in part by
             Participant.

      If any provision of this Section 7 should be found by any court of
      competent jurisdiction to be unreasonable by reason of its being too
      broad as to the period of time, territory, and/or scope, then, and in
      that event, such provision shall nevertheless remain valid and fully
      effective, but shall be considered to be amended so that the period of
      time, territory, and/or scope set forth shall be changed to be the
      maximum period of time, the largest territory, and/or the broadest scope,
      as the case may be, which would be found reasonable and enforceable by
      such court.

8.    Rights Upon Termination or Competition.  If the Committee discovers that
      Participant has engaged in any conduct prohibited by Section 7 or if
      Participant





                                       5
<PAGE>   6

      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 require Participant to (i) sell to Perot
      Systems all or any part of the Restricted Stock (both Vested Stock and
      Unvested Stock) then held by Participant, at the price per share paid by
      Participant 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 5 above, minus the
      amount or value, as applicable, of any dividends or distributions paid on
      such Restricted Stock and (ii) if any shares of Restricted Stock have
      been sold or otherwise transferred by Participant (including any sale to
      the Company), then at Perot Systems' option Participant shall pay to
      Perot Systems an amount in cash with respect to each share of Restricted
      Stock not still so held equal to the greater of the value of the proceeds
      received by Participant for such share or the Market Value of such share
      on the first date on which such share is no longer held by Participant,
      less in either case the price paid by Participant for such share 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 5 above, minus the amount or value, as
      applicable, of any dividends or distributions paid on such Restricted
      Stock. If and when Perot Systems is entitled to exercise the rights
      specified in this Section 8, as provided in Section 6 above, then, upon
      the demand of Perot Systems, Participant shall sell to Perot Systems all
      or any part of the Unvested Stock then held by Participant, at the price
      per share paid by Participant 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 5 above,
      minus the amount or value, as applicable, of any dividends or
      distributions paid on such Restricted Stock.

9.    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.





                                       6
<PAGE>   7
10.   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 Systems may require that any
      certificates or other property representing shares of Unvested Stock
      remain in the possession of the Company 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.

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

12.   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.

13.   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 the Company.  Either party may at
      any time change its address for notification purposes by giving





                                       7
<PAGE>   8
      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 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.

14.   Remedies.  Perot Systems shall 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.

15.   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 shall
      not, and shall not have the power to, assign this Agreement or any rights
      relating to this Agreement without the prior written consent of Perot
      Systems.  By signing this Agreement, Participant consents to the personal
      jurisdiction of such courts in any such action.

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

17.   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 shall not be affected thereby.

18.   Headings.  The section headings used herein are for reference and
      convenience only and shall not enter into the interpretation hereof.

19.   Governing Law.  This Agreement shall be governed by and construed in
      accordance with the laws of the State of Texas, without regard to the
      choice of law rules in such law.

20.   Entire Agreement.  This Agreement, together with the Plan and any
      procedures adopted by the Committee thereunder, constitutes the entire
      agreement between the parties hereto with respect to its subject matter
      and may be waived or modified only in writing.

                           PEROT SYSTEMS CORPORATION
                        1996 NON-EMPLOYEE DIRECTOR STOCK
                     OPTION/RESTRICTED STOCK INCENTIVE PLAN


1.       Purpose

         The purpose of the Perot Systems Corporation 1996 Non-Employee
Director Stock Option/Stock Incentive Plan, as amended, is to benefit the
Company and its stockholders by helping to secure and retain for them the
services of non-employee directors with increased incentives to exert maximum
efforts to assure the financial success of the Company.

2.       Administration

         The Board of Directors of Perot Systems will administer the Plan.  The
Board of Directors may interpret the Plan, define terms used in the Plan,
answer questions arising under the Plan, and adopt and amend rules and
regulations for the Plan.  To the extent permitted by law, any determination
made by the Board of Directors in administering the Plan will be conclusive.

3.       Amount of Stock

         The Board of Directors will reserve for issuance under the Plan not
more than  400,000 shares of the Common Stock of the Company, par value $0.01
per share.  These shares may be authorized and unissued shares or issued shares
acquired by the Company.  If options granted under the Plan terminate or expire
without being exercised, new options may be granted covering the shares not
purchased under the lapsed options.

4.       Eligibility

         Any person who is not an employee of the Company but is a member of
the Board of Directors of the Company (other than Ross Perot, Jr.) is eligible
to receive an award under the Plan, and thereby become a participant in the
Plan, in consideration of service to the Company in a capacity not involving
the offer or sale of securities in a capital-raising transaction.




                                                                        Page 1
<PAGE>   2
5.       Stock Option/Restricted Stock Agreements

         All awards granted under the Plan are to be evidenced by a Stock
Option Agreement in the form attached as Exhibit A and/or Restricted Stock
Agreement in the form attached as Exhibit B, as applicable, between the Company
and the participant.

6.       Awards

         Subject to change at the discretion of the Chairman, upon the
commencement of service and upon the completion of the original vesting period
(without regard to any acceleration of such vesting) for all previously issued
restricted shares and/or options for an eligible director, such director will
be entitled to elect, within 30 days of such commencement, either (i) the award
of an option to purchase 30,000 shares of Common Stock on the terms set forth
in Section 7 or (ii) the right to purchase 30,000 shares of Restricted Stock on
the terms set forth in Section 8.  In the event that a director does not
specify the type of award within the 30 day period set forth above, that
director shall be awarded an option on the terms set forth in Section 7.

7.       Options

         If any change is made in the shares of Common Stock of the Company
(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 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 the shares subject to outstanding Stock
Option Agreements under the Plan as the Board of Directors determines are
equitable to preserve the respective rights of the participants in the Plan.

         Stock Option Agreements between the Company and participants who have
received options under the Plan must contain substantially the following terms
and conditions:

         (a)     The option exercise price will be the fair market value of the
                 shares underlying the option on the date the option is
                 granted, which,

                 (i)      if the shares are publicly traded, will be the
                          closing sale price on such date in the market in
                          which the shares underlying the option 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



                                                                       Page 2

                          no closing sale price is available, the closing bid
                          price on such date as quoted in the NASDAQ system, if
                          the shares are quoted in the 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 the shares are not publicly traded, 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.

         (b)     No option may be exercised:

                 (i)      except to the extent that such option has vested.

                          the participants service as a director of the Company
                          unless such participant is removed for Cause or
                          resigns.  For purposes of this Agreement, "Cause"
                          means for the conviction of a felony (other than a
                          traffic violation) or the commission of material
                          fraud with regard to the Company.

                 (ii)     after the expiration date, which will be the eleventh
                          anniversary of the award of the option.

                 (iii)    before the satisfaction of the other conditions set
                          forth in the Stock Option Agreement.

                 (iv)     unless written notice of the exercise is delivered to
                          the Company specifying the number of shares to be
                          purchased and payment in full is made for the shares
                          being purchased at the time of the exercise, and such
                          payment is made



                                                                       Page 3

                                  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 the Company's earnings and having a
                                  fair market value equal to the cash exercise
                                  price, such fair market value to be
                                  determined in accordance with Paragraph 7(a)
                                  above, or

                          (C)     by a combination of such cash or check and 
                                  shares.

                 (v)      upon termination of participant's service as a
                          director of the Company if such participant is
                          removed for Cause or resigns.

                 (vi)     if participant's service ceases (other than by
                          removal for Cause or resignation), more than two
                          years after the later of (A) vesting of the
                          participant's options is completed or (B) such
                          service ceases; provided that in no case shall an
                          option be exercisable after the expiration date set
                          forth in clause (ii) above.

         (c)     Shares of Common Stock issued upon exercise of any option
                 outstanding under the Plan will be subject to the restrictions
                 set forth in the Stock Option Agreement.

                 market value of the shares, but will not be less than the par
                 value of the shares or otherwise inconsistent with applicable
                 law.  The fair market value,

                 (i)      if the shares are publicly traded, will be the
                          closing sale price on such date in the market in
                          which the shares underlying the option 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 NASDAQ system, if
                          the shares are quoted in the



                                                                        Page 4

                          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 the shares are not publicly traded, 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.

         (b)     The period during which a participant may exercise a right to
                 purchase shares will end 60 days following the award of the
                 right.

         (c)     The right to purchase shares may be exercised:

                 (i)      as to all or any part of the shares subject to the
                          right;

                 (ii)     by delivering written notice of the exercise to the
                          Company specifying the number of shares to be
                          purchased and paying the purchase price in cash or
                          check in United States dollars;

                 (iii)    only while the participant is serving the Company in
                          a capacity that renders the participant eligible to
                          participate in the Plan; and

                 (iv)     only by the participant awarded the right and not by
                          any transferee, assignee, or successor.

         (d)     Shares purchased pursuant to rights to purchase restricted
                 shares awarded under the Plan will be subject to the
                 restrictions set forth in the Restricted Stock Agreement.

         (e)     The participant will have the rights of a shareholder with
                 respect to shares purchased under the Plan, including the
                 right to vote the shares and to receive any dividends paid on
                 the shares, from the date of purchase 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 shares, whether resulting from a
                 subdivision, combination or reclassification of the shares of
                 any issuer thereof or received in exchange for shares 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 shares or received
                 in payment of the principal of or in redemption of the shares
                 (either at maturity, upon call




                                                                     Page 5

                 for redemption or otherwise), shall remain in the possession
                 of the Company for as long as the Company's right to
                 repurchase such shares shall not have terminated.

         (f)     If the participant sells, assigns, conveys, donates, pledges,
                 transfers, or otherwise disposes of or encumbers any
                 restricted shares before the lapse, expiration, or termination
                 of the restrictions imposed on the shares under Paragraph
                 8(d), the Company will have the right, in addition to such
                 other rights and remedies as may be available to it (including
                 the right to restrain or set aside the transaction),
                 exercisable by written notice to the owner thereof at any time
                 within 180 days after its discovery of such transaction, to
                 repurchase all or any part of the shares as to which the
                 restrictions have not lapsed, expired, and terminated, for
                 cash in an amount equal to the purchase price paid to the
                 Company for such shares, plus simple interest at 8% per annum
                 from the date of payment by the participant to the date of

                 value, as applicable, of any dividends or distributions paid
                 on such shares.

         (g)     If the participant is removed for Cause or resigns as a
                 director before the restrictions imposed on the shares under
                 Paragraph 8(d) lapse, expire, or terminate, the Company will
                 have the right for 180 days following the cessation of service
                 to repurchase all or any part of the shares as to which the
                 restrictions have not lapsed, expired, and terminated, for

                 Company for such shares, plus simple interest at 8% per annum
                 from the date of payment by the participant to the date of
                 offer of tender of payment by the Company, minus the amount or
                 value, as applicable, of any dividends or distributions paid
                 on such shares.

9.       Miscellaneous Provisions

         (a)     Neither the Plan nor any action taken under the Plan is to be
                 construed as giving any person a right to be retained in the
                 service of the Company.

         (b)     A participant's rights under and interest in the Plan, options
                 and rights to purchase shares issued under the Plan, and
                 shares purchased under the Plan that remain subject to
                 restrictions imposed under Paragraph 8(d) are not subject to
                 execution, levy, garnishment, attachment, pledge, bankruptcy,
                 or any obligation or liability of the participant.

         (c)     The Plan, awards under the Plan, the exercise of options and
                 rights awarded under the Plan, and the obligation of the
                 Company to issue or




                                                                       Page 6

                 all applicable federal and state laws, rules, and regulations
                 and to such approvals as may be required by any government or
                 regulatory agency.  The Company is permitted a reasonable
                 delay in issuing and delivering any shares under the Plan in
                 order to accommodate compliance with such laws, rules,
                 regulations, and approvals, including:

                 (i)      the listing of such shares on any registered national
                          securities exchange or approval for quotation in the
                          NASDAQ system, and

                 (ii)     the completion of any registration or qualification
                          of such issuance or delivery under any federal or
                          state law or any ruling or regulation of any
                          government body that the Company may, in its sole
                          discretion, determine to be necessary or advisable.

         (d)     It shall be a condition to the obligation of the Company to
                 issue and deliver shares under the Plan that the participant
                 (or any person entitled to act on the participant's behalf)
                 pay to the Company, upon its demand, such amount as may be
                 requested by the Company for the purpose of satisfying any
                 liability to withhold federal, state, local, or foreign income
                 or other taxes.  If the amount requested is not paid, the
                 Company may refuse to issue and deliver shares.

         (e)     The Company will bear the expenses of the Plan.

         (f)     By accepting any benefit under the Plan, a participant and
                 each person claiming under or through a participant will be
                 conclusively deemed to have indicated the person's acceptance
                 and ratification of, and consent to, any action taken under
                 the Plan by the Company or its Board of Directors.

10.      Adjustments, Amendment and Termination

         (a)     The Board of Directors will have the right, in its sole
                 discretion, to accelerate the exercisability of any options
                 awarded or the lapse, expiration, or termination of any
                 restrictions imposed on shares under Paragraph 8(d), and to
                 waive any conditions for such exercisability, lapse,
                 expiration, or termination, including the condition that an
                 option may not be exercised after the participant ceases to
                 serve the Company.

         (b)     If any change is made in the shares reserved for issuance
                 under the Plan (such as by stock dividend, stock split, or
                 merger or consolidation), the Board of Directors will make
                 such adjustments in the number and kind of shares reserved for
                 issuance under the Plan and the purchase price per




                                                                     Page 7
<PAGE>   8
                 share of shares covered by options outstanding under the Plan
                 as the Board of Directors determines are equitable to preserve
                 the rights of participants in the Plan.

         (c)     The Board of Directors may amend or terminate the Plan at any
                 time, except that it may not amend or terminate the Plan in a
                 way that materially and adversely affects any right of a
                 participant with respect to any award previously granted under
                 the Plan without the participant's written consent.

11.      Duration of Plan

         Unless the Board of Directors has taken action under Paragraph 10(c)
terminating the Plan beforehand, the Plan will terminate for purposes of
issuing new options and Restricted Stock awards ten years after its effective
date.

12.      Severability

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

13.      Effect on Other Plans

         The adoption of the Plan has no effect on awards made or to be made
under other equity incentive plans of the Company.

14.      Governing Law

         The Plan is to be governed and construed under the law of the State of
Texas, without regard to the State's choice of law rules.

                     OPTION/RESTRICTED STOCK INCENTIVE PLAN


                           RESTRICTED STOCK AGREEMENT




THIS AGREEMENT, dated as of ________________________, _____, is by and between
Perot Systems Corporation, a Delaware corporation ("Perot Systems" or the
"Company"), and ________________________________________________ ("Participant"
).


                                   WITNESSETH


WHEREAS, Perot Systems has adopted the Perot Systems Corporation 1996
Non-Employee Director Stock Option/Restricted Stock Incentive Plan (the "Plan")
to enable non-employee directors of 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 Participant is entitled, and has elected, to receive this right to
purchase restricted shares of Common Stock pursuant to the Plan and 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.       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 right to purchase from Perot Systems ______ of restricted
         shares of Common Stock, at the purchase price, and in accordance with
         the schedule for termination of transfer restrictions specified on
         Attachment A hereto.

         (b)     The right to purchase restricted shares of Common Stock
         evidenced by this Agreement may be exercised by delivering written
         notice of the exercise, in substantially the form of Attachment B, to
         Perot Systems within 30 days of the

<PAGE>   2
         date of this Agreement and paying in full the purchase price for such
         shares in cash or check in United States dollars. Such right is not
         transferable and may be exercised only by Participant, and only while
         Participant is serving Perot Systems as a member of the Perot Systems
         Board of Directors.  "Restricted Stock" shall mean the Common Stock
         issued to Participant pursuant to the Plan and this Agreement,
         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.

2.       Restrictions on Shares.

         (a)     Restricted Stock purchased under this Agreement may not be
         sold, assigned, conveyed, donated, pledged, transferred, or otherwise
         disposed of or encumbered until the later of (i) the date set forth in
         Attachment A as the date for termination of the transfer restrictions
         on such Restricted Stock, or (ii) six months after the Common Stock is
         publicly tradable.

         (b)     If Participant sells, assigns, conveys, donates, pledges,
         transfers, or otherwise disposes of or encumbers any of the Restricted
         Stock purchased under this Agreement before the date set forth in
         Attachment A for termination of the transfer restrictions on such
         Restricted Stock, Perot Systems will have the right, in addition to
         such other rights and remedies as may be available to it (including
         the right to restrain or set aside the transaction), exercisable by
         written notice to the owner thereof at any time within 180 days after
         its discovery of such transaction, to repurchase all or any part of
         the Restricted Stock as to which the transfer restrictions have not
         terminated, for cash in an amount equal to the purchase price paid to
         Perot Systems for such Restricted Stock, plus simple interest on such
         amount at the rate of 8% per annum from the date of payment by
         Participant to the date of offer of tender of payment by Perot Systems
         as set forth in Section 2(d) below, minus the amount or value, as
         applicable, of any dividends or distributions paid on such Restricted
         Stock.

         (c)     If Participant is removed as a member of the Perot Systems
         Board of Directors for Cause or resigns, before the date set forth in
         Attachment A for termination of the transfer restrictions on any
         Restricted Stock purchased under this Agreement, Perot Systems will
         have the right for 180 days following the cessation of service to
         repurchase all or any part of the Restricted Stock as to which the
         transfer restrictions have not terminated, for cash in an amount equal
         to the purchase price paid to Perot Systems for such Restricted Stock,
         plus simple interest on such amount at the rate of 8% per annum from
         the date of payment by Participant to the date of offer of tender of
         payment by Perot Systems as set






                                       2
<PAGE>   3
         forth in Section 2(d) below, minus the amount or value, as applicable,
         of any dividends or distributions paid on such Restricted Stock.

         (d)     Whenever Perot Systems has a right to buy back shares of
         Restricted Stock, Perot Systems may exercise its right by notifying
         Participant or the subsequent holder of the Company's election to
         exercise its right within the designated exercise period.  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, the Restricted Stock and any previously issued
         certificate representing shares of Restricted 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 endorsed certificate or
         stock power 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 within 2
         business days of the tender of the Restricted Stock.  If the person
         from whom the Restricted Stock are to be bought back has not complied
         with an obligation to return a certificate and stock power
         representing shares to be bought back, however, the Company 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.

         (e)     For purposes of this Agreement, "Cause" means for the
         conviction of a felony (other than a traffic violation) or the
         commission of a material fraud with respect to the Company.

3.       Company's Right of First Refusal.

         (a)     Unless and until Restricted Stock purchased under this
         Agreement are publicly traded, Perot Systems will have a right of
         first refusal to purchase such Restricted Stock if the holder of the
         Restricted Stock desires or is obligated to sell or otherwise transfer
         the shares after the date set forth in Attachment A for termination of
         the transfer restrictions on such Restricted Stock, 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 Restricted Stock who desires or is
         obligated to sell or otherwise transfer it before it are publicly
         traded after the date set forth in Attachment A for termination of the
         transfer restrictions on such Restricted Stock, 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 Restricted Stock proposed to be sold or
         transferred by notifying the holder within 30 days of its receipt of
         the notice of its election to






                                       3
<PAGE>   4
         exercise its right of first refusal and tendering the purchase price
         of the Restricted Stock as soon as reasonably practicable thereafter.

         (c)     The purchase price at which Perot Systems will purchase
         Restricted Stock under its right of first refusal will be its 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 the Company conducted on or before the date of receipt of
         the notice of the proposed sale or transfer.

         (d)     For purposes of this Section, the term "publicly traded" means
         shares of Restricted Stock have been listed on a registered national
         securities exchange or approved for quotation in the National
         Association of Securities Dealers Automated Quotation ("NASDAQ")
         system.

4.       Compliance with Securities Laws.

         (a)     Participant acknowledges that the right to purchase shares of
         Common Stock evidenced by this Agreement and any shares purchased
         under this Agreement 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)     Neither Participant nor any successor in interest of
         Participant will sell or otherwise transfer any Restricted Stock
         purchased under this Agreement in any way that might result in a
         violation of any federal or state securities laws or regulations.

         (c)     Perot Systems may require Participant or any subsequent holder
         of Restricted Stock purchased under this Agreement to provide Perot
         Systems, before any sale or other transfer of such shares, with such
         representations, commitments, and opinions regarding compliance with
         applicable securities laws and regulations as Perot Systems may deem
         necessary or advisable.

         property representing Restricted Stock.  Each such certificate will
         bear such legends as the Board 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, 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 until the date set forth on Attachment
         A for termination of the transfer restriction on such Restricted
         Stock.

                           PEROT SYSTEMS CORPORATION
                        1996 NON-EMPLOYEE DIRECTOR STOCK
                     OPTION/RESTRICTED STOCK INCENTIVE PLAN

                   S T O C K  O P T I O N  A G R E E M E N T


THIS AGREEMENT, dated as of, ________, _____, is by and between Perot Systems
Corporation, a Delaware corporation ("Perot Systems" or the "Company"), and
_______ ("Participant").

                                   WITNESSETH

WHEREAS, Perot Systems has adopted the Perot Systems Corporation 1996
Non-Employee Director Stock Option/Restricted Stock Incentive Plan (the "Plan")
to enable non-employee directors of 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 Participant is entitled, and has elected, to receive this option
to purchase shares of Common Stock pursuant to the Plan and 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 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 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 [30,000][_______] of shares of Common Stock,
    at the purchase price, and in accordance with the schedule specified on
    Attachment A hereto.


                                      -1-
<PAGE>   2
    (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 Attachment 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 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 National Association of
    Securities Dealers Automated Quotation ("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 unvested 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 member of the Perot Systems
    Board of Directors, a member of the Perot Systems Advisory Board, [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 thirty
    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





                                    - 3 -
<PAGE>   4
    proposed to be sold or transferred by notifying the holder within 30 days
    of its 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 Systems conducted
    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>   5
    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 l(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 this Agreement,
     Participant consents to the personal jurisdiction of such courts in any
     such action.

     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.

     consistent with the Plan and only by a written instrument signed by both

                           PEROT SYSTEMS CORPORATION
              ADVISOR STOCK OPTION/RESTRICTED STOCK INCENTIVE PLAN


1.       Purpose

         The purpose of the Perot Systems Corporation Advisor Stock
Option/Stock Incentive Plan, as amended, is to benefit the Company and its
stockholders by helping to secure and retain for them the services of
non-employee directors, advisors, and consultants with increased incentives to
exert maximum efforts to assure the financial success of the Company.

2.       Administration

         A Committee consisting of at least three members of the Board of
Directors of Perot Systems will administer the Plan and award stock options
and/or rights to purchase shares of restricted stock under the Plan.  The
Committee will be appointed by the Board, and may interpret the Plan, define
terms used in the Plan, answer questions arising under the Plan, and adopt and
amend rules and regulations for the Plan.  To the extent permitted by law, any
determination made by the Committee in administering the Plan will be
conclusive.

3.       Amount of Stock

         The Board of Directors will reserve for issuance under the Plan not
more than 500,000 shares of the Common Stock of the Company, par value $0.01
per share.  These shares may be authorized and unissued shares or issued shares
acquired by the Company.  If options granted under the Plan terminate or expire
without being exercised, new options may be granted covering the shares not
purchased under the lapsed options.

4.       Eligibility

         Any person who is not an employee of the Company but is a member of
the Board of Directors or Advisory Board of the Company or a consultant under
contract to the Company is eligible to receive an award under the Plan, and
thereby become a participant in the Plan, in consideration of past service to
the Company in a capacity not involving the offer or sale of securities in a
capital-raising transaction.  The adoption of the Plan, however, does not
confer on any person any right to be granted an award under the Plan, except to
the extent and upon the terms and conditions determined by the Committee.


                                                                          Page 1
<PAGE>   2
5.       Stock Option/Restricted Stock Agreements

         All awards granted under the Plan are to be evidenced by a Stock
Option Agreement and/or Restricted Stock Agreement, as applicable, between the
Company and the participant in the form prescribed by the Committee in
accordance with the Plan.  Each such Agreement is to contain substantially the
terms and conditions of the award to the participant approved by the Committee,
including the terms and conditions set forth in Paragraph 6 if an option is
awarded and those set forth in Paragraph 7 if a right to purchase shares of
restricted stock is awarded.  Each such Agreement may also contain such other
terms and conditions as the Committee deems appropriate that are not
inconsistent with the Plan.

6.       Option Awards

         If any change is made in the shares of Common Stock of the Company
(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, as appropriate, 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
the 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 in the Plan.

         Stock Option Agreements between the Company and participants who have
been granted options under the Plan must contain substantially the following
terms and conditions:

         (a)     The option exercise price will be the fair market value of the
                 shares underlying the option on the date the option is
                 granted, which,

                 (i)      if the shares are publicly traded, will be the
                          closing sale price on such date in the market in
                          which the shares underlying the option 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 NASDAQ system, if
                          the shares are quoted in the 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





                                                                          Page 2
<PAGE>   3
                 (ii)     if the shares are not publicly traded, will be their
                          fair market value, as determined in good faith by the
                          Board of Directors, as of the most recent June 30 or
                          December 31 on or before such date.

         (b)     The option will not be transferable except upon the
                 participant's death by will or by the laws of descent and
                 distribution.  During the participant's lifetime, only the
                 participant may exercise the option.

         (c)     No option may be exercised:

                 (i)      before the date or dates it becomes exercisable,
                          which date or dates will be established by the
                          Committee and set forth in the Stock Option Agreement
                          and may not be later than ten years after the award
                          of the option;

                 (ii)     after the date or dates it expires, which date or
                          dates will be established by the Committee and may
                          not be later than 11 years after the award of the
                          option;

                 (iii)    before the satisfaction of such other conditions as
                          are established by the Committee and set forth in the
                          Stock Option Agreement;

                 (iv)     unless written notice of the exercise is delivered to
                          the Company specifying the number of shares to be
                          purchased and payment in full is made for the shares
                          being purchased at the time of the exercise, and such
                          payment is made

                          (A)     in cash or by check in United States dollars,
                                  or

                          (B)     by tendering to the Company 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 the Company's earnings and having a
                                  fair market value equal to the cash exercise
                                  price, such fair market value to be
                                  determined in accordance with Paragraph 6(a)
                                  above, or

                          (C)     by a combination of such cash or check and
                                  shares; and

                 (v)      after the participant ceases to serve the Company as
                          a director, member of its Advisory Board, consultant
                          under contract, or full-time employee, except as
                          provided in the Stock Option Agreement





                                                                          Page 3
<PAGE>   4
                          and as otherwise determined by the Committee, in its
                          sole discretion.

7.       Restricted Stock Awards

         Restricted Stock Agreements between the Company and participants who
have been awarded rights to purchase shares of Restricted Stock under the Plan
must contain substantially the following terms and conditions:

         (a)     The purchase price per share for the shares will be the price
                 determined by the Committee, but will not be less than the par
                 value of the shares or otherwise inconsistent with applicable
                 law.

         (b)     The period during which a participant may exercise a right to
                 purchase shares will be determined by the Committee, but must
                 end within 60 days of the award of the right.

         (c)     The right to  purchase shares may be exercised:

                 (i)      as to all or any part of the shares subject to the 
                          right;

                 (ii)     by delivering written notice of the exercise to the
                          Company specifying the number of shares to be
                          purchased and paying the purchase price in cash or
                          check in United States dollars;

                 (iii)    only while the participant is serving the Company in
                          a capacity that renders the participant eligible to
                          participate in the Plan; and

                 (iv)     only by the participant awarded the right and not by
                          any transferee, assignee, or successor.

         (d)     Shares purchased pursuant to rights to purchase restricted
                 shares awarded under the Plan:

                 (i)      may not be sold, assigned, conveyed, donated,
                          pledged, transferred, or otherwise disposed of or
                          encumbered for the period during which they are
                          restricted, which period

                          (A)     will be determined by the Committee and set 
                                  forth in the Restricted Stock Agreement,

                          (B)     may lapse as to specified amounts of such 
                                  shares on different dates, and





                                                                          Page 4

                          (C)     may not exceed ten years measured from the 
                                  date the shares are purchased; and

                 (ii)     will be subject to such additional restrictions as
                          may be determined by the Committee and set forth in
                          the Restricted Stock Agreement.

         (e)     The participant will have the rights of a shareholder with
                 respect to shares purchased under the Plan, including the
                 right to vote the shares and to receive any dividends paid on
                 the shares, from the date of purchase 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 shares, whether resulting from a
                 subdivision, combination or reclassification of the shares of
                 any issuer thereof or received in exchange for shares 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 shares or received
                 in payment of the principal of or in redemption of the shares
                 (either at maturity, upon call for redemption or otherwise),
                 shall remain in the possession of the Company for as long as
                 the Company's right to repurchase such shares shall not have
                 terminated.

         (f)     If the participant sells, assigns, conveys, donates, pledges,
                 transfers, or otherwise disposes of or encumbers any
                 restricted shares before the lapse, expiration, or termination
                 of the restrictions imposed on the shares under Paragraph
                 7(d), the Company will have the right, in addition to such
                 other rights and remedies as may be available to it (including
                 the right to restrain or set aside the transaction),
                 exercisable by written notice to the owner thereof at any time
                 within 180 days after its discovery of such transaction, to
                 repurchase all or any part of the shares as to which the
                 restrictions have not lapsed, expired, and terminated, for
                 cash in an amount equal to the purchase price paid to the
                 Company for such shares, plus simple interest at 8% per annum
                 from the date of payment by the participant to the date of
                 offer of tender of payment by the Company, minus the amount or
                 value, as applicable, of any dividends or distributions paid
                 on such shares.

         (g)     If the participant ceases to serve the Company as a director,
                 member of its Advisory Board, consultant under contract, or
                 full-time employee before the restrictions imposed on the
                 shares under Paragraph 7(d) lapse, expire, or terminate, the
                 Company will have the right for 180 days following the
                 cessation of service to repurchase all or any part of the
                 shares as to which





                                                                          Page 5
<PAGE>   6
                 the restrictions have not lapsed, expired, and terminated, for
                 cash in an amount equal to the purchase price paid to the
                 Company for such shares, plus simple interest at 8% per annum
                 from the date of payment by the participant to the date of
                 offer of tender of payment by the Company, minus the amount or
                 value, as applicable, of any dividends or distributions paid
                 on such shares.

8.       Miscellaneous Provisions

         (a)     Neither the Plan nor any action taken under the Plan is to be
                 construed as giving any person a right to be retained in the
                 service of the Company.

         (b)     A participant's rights under and interest in the Plan, options
                 and rights to purchase shares issued under the Plan, and
                 shares purchased under the Plan that remain subject to
                 restrictions imposed under Paragraph 7(d) are not subject to
                 execution, levy, garnishment, attachment, pledge, bankruptcy,
                 or any obligation or liability of the participant.

         (c)     The Plan, awards under the Plan, the exercise of options and
                 rights awarded under the Plan, and the obligation of the
                 Company to issue or deliver shares under such options and
                 rights are subject to all applicable federal and state laws,
                 rules, and regulations and to such approvals as may be
                 required by any government or regulatory agency.  The Company
                 is permitted a reasonable delay in issuing and delivering any
                 shares under the Plan in order to accommodate compliance with
                 such laws, rules, regulations, and approvals, including:

                 (i)      the listing of such shares on any registered national
                          securities exchange or approval for quotation in the
                          NASDAQ system, and

                 (ii)     the completion of any registration or qualification
                          of such issuance or delivery under any federal or
                          state law or any ruling or regulation of any
                          government body that the Company may, in its sole
                          discretion, determine to be necessary or advisable.

         (d)     It shall be a condition to the obligation of the Company to
                 issue and deliver shares under the Plan that the participant
                 (or any person entitled to act on the participant's behalf)
                 pay to the Company, upon its demand, such amount as may be
                 requested by the Company for the purpose of satisfying any
                 liability to withhold federal, state, local, or foreign income
                 or other taxes.  If the amount requested is not paid, the
                 Company may refuse to issue and deliver shares.





                                                                          Page 6
<PAGE>   7
         (f)     The Company will bear the expenses of the Plan.

         (g)     By accepting any benefit under the Plan, a participant and
                 each person claiming under or through a participant will be
                 conclusively deemed to have indicated the person's acceptance
                 and ratification of, and consent to, any action taken under
                 the Plan by the Company or its Board of Directors.

9.       Adjustments, Amendment and Termination

         (a)     The Committee will have the right, in its sole discretion, to
                 accelerate the exercisability of any options awarded or the
                 lapse, expiration, or termination of any restrictions imposed
                 on shares under Paragraph 7(d), and to waive any conditions
                 for such exercisability, lapse, expiration, or termination,
                 including the condition that an option may not be exercised
                 after the participant ceases to serve the Company.

         (b)     If any change is made in the shares reserved for issuance
                 under the Plan (such as by stock dividend, stock split, or
                 merger or consolidation), the Board of Directors will make
                 such adjustments in the number and kind of shares reserved for
                 issuance under the Plan and the purchase price per share of
                 shares covered by options outstanding under the Plan as the
                 Board determines are equitable to preserve the rights of
                 participants in the Plan.

         (c)     The Board may amend or terminate the Plan at any time, except
                 that it may not amend or terminate the Plan in a way that
                 materially and adversely affects any right of a participant
                 with respect to any award previously granted under the Plan
                 without the participant's written consent.

10.      Duration of Plan

         Unless the Board has taken action under Paragraph 9(c) terminating the
Plan beforehand, the Plan will terminate for purposes of issuing new options
and Restricted Stock awards ten years after its effective date.

11.      Severability

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





                                                                          Page 7
<PAGE>   8
12.      Effect on Other Plans

         The adoption of the Plan has no effect on awards made or to be made
under other equity incentive plans of the Company.

13.      Governing Law

         The Plan is to be governed and construed under the law of the State of
Texas, without regard to the State's choice of law rules.





                                                                          Page 8

                           PEROT SYSTEMS CORPORATION
              ADVISOR STOCK OPTION/RESTRICTED STOCK INCENTIVE PLAN


                           RESTRICTED STOCK AGREEMENT




THIS AGREEMENT, dated as of ________________________, 1996, is by and between
Perot Systems Corporation, a Delaware corporation ( "Perot Systems" or the
"Company" ), and ________________________________________________
("Participant" ).



                                   WITNESSETH


WHEREAS, Perot Systems has adopted the Perot Systems Corporation Advisor Stock
Option/Restricted Stock Incentive Plan ( the "Plan" ) to enable non-employee
directors and 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 the Plan has selected Participant to
participate in the Plan and has determined to grant Participant the right to
purchase restricted 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.       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 right to purchase from Perot Systems the number of
         restricted shares of Common Stock, at the purchase price, and in
         accordance with the schedule for termination of transfer restrictions
         specified on Attachment A hereto, unless, prior to the date set forth
         for vesting, the Chief Executive Officer of Perot Systems modifies
         such attachment by delaying or canceling vesting prior to the
         respective vesting date.  If the Chief Executive Officer so determines
         to delay or cancel the vesting, Participant will be


                                      -1-
<PAGE>   2
         notified of the determination in advance of the date provided for
         vesting.  Perot Systems will thereupon modify Attachment A in
         accordance with the determination.

         (b)     The right to purchase restricted shares of Common Stock
         evidenced by this Agreement may be exercised by delivering written
         notice of the exercise, in substantially the form of Attachment B, to
         Perot Systems within 30 days of the date of this Agreement and paying
         in full the purchase price for such shares in cash or check in United
         States dollars. Such right is not transferable and may be exercised
         only by Participant, and only while Participant is serving as a member
         of the Advisory Board or Board of Directors of Perot Systems, or as a
         consultant under contract with Perot Systems.  "Restricted Stock"
         shall mean the Common Stock issued to Participant pursuant to the Plan
         and this Agreement, 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.

2.       Restrictions on Shares.

         (a)     Restricted Stock purchased under this Agreement may not be
         sold, assigned, conveyed, donated, pledged, transferred, or otherwise
         disposed of or encumbered until the date set forth in Attachment A as
         the date for termination of the transfer restrictions on such
         Restricted Stock.

         (b)     If Participant sells, assigns, conveys, donates, pledges,
         transfers, or otherwise disposes of or encumbers any of the Restricted
         Stock purchased under this Agreement before the date set forth in
         Attachment A for termination of the transfer restrictions on such
         Restricted Stock, Perot Systems will have the right, in addition to
         such other rights and remedies as may be available to it (including
         the right to restrain or set aside the transaction), exercisable by
         written notice to the owner thereof at any time within 180 days after
         its discovery of such transaction, to repurchase all or any part of
         the Restricted Stock as to which the transfer restrictions have not
         terminated, for cash in an amount equal to the purchase price paid to
         Perot Systems for such Restricted Stock, plus simple interest on such
         amount at the rate of 8% per annum from the date of payment by
         Participant to the date of offer of tender of payment by Perot Systems
         as set forth in Section 2(d) below, minus the amount or value, as
         applicable, of any dividends or distributions paid on such Restricted
         Stock.

         (c)     If Participant ceases to serve Perot Systems in at least one
         of the following capacities: a member of its Advisory Board, a member
         of its Board of Directors, a consultant under contract, or full time
         Employee for any reason whatsoever, before the date set forth in
         Attachment A for termination of the transfer





                                    - 2 -
<PAGE>   3
         restrictions on any Restricted Stock purchased under this Agreement,
         Perot Systems will have the right for 180 days following the cessation
         of service to repurchase all or any part of the Restricted Stock as to
         which the transfer restrictions have not terminated, for cash in an
         amount equal to the purchase price paid to Perot Systems for such
         Restricted Stock, plus simple interest on such amount at the rate of
         8% per annum from the date of payment by Participant to the date of
         offer of tender of payment by Perot Systems as set forth in Section
         2(d) below, minus the amount or value, as applicable, of any dividends
         or distributions paid on such Restricted Stock.

         (d)     Whenever Perot Systems has a right to buy back shares of
         Restricted Stock, Perot Systems may exercise its right by notifying
         Participant or the subsequent holder of the Company's election to
         exercise its right within the designated exercise period.  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, the Restricted Stock and any previously issued
         certificate representing shares of Restricted 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 endorsed certificate or
         stock power 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 within 2
         business days of the tender of the Restricted Stock.  If the person
         from whom the Restricted Stock are to be bought back has not complied
         with an obligation to return a certificate and stock power
         representing shares to be bought back, however, the Company 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.

3.       Company's Right of First Refusal.

         (a)     Unless and until Restricted Stock purchased under this
         Agreement are publicly tradable, Perot Systems will have a right of
         first refusal to purchase such Restricted Stock if the holder of the
         Restricted Stock desires or is obligated to sell or otherwise transfer
         the shares after the date set forth in Attachment A for termination of
         the transfer restrictions on such Restricted Stock, 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 Restricted Stock who desires or is
         obligated to sell or otherwise transfer them before they are publicly
         tradable after the date set forth in Attachment A for termination of
         the transfer restrictions on such Restricted Stock, must give Perot
         Systems written notice of the proposed sale or other transfer. The
         notice must include the name of the proposed purchaser or




                                    - 3 -
<PAGE>   4
         transferee and describe the circumstances of the transfer. Perot
         Systems may purchase any or all of the Restricted Stock proposed to be
         sold or transferred by notifying the holder within 30 days of its
         receipt of the notice of its election to exercise its right of first
         refusal and tendering the purchase price of the Restricted Stock as
         soon as reasonably practicable thereafter.

         (c)     The purchase price at which Perot Systems will purchase
         Restricted Stock under its right of first refusal will be their fair
         market value, as determined in good faith by the Board of Directors of
         the Company, as of the most recent June 30 or December 31 on or before
         the date of receipt of the notice of the proposed sale or transfer.

         (d)     For purposes of this Section, the term "publicly tradable"
         means shares of Restricted Stock have been listed on a registered
         national securities exchange or approved for quotation in the National
         Association of Securities Dealers Automated Quotation ("NASDAQ")
         system.

4.       Compliance with Securities Laws.

         (a)     Participant acknowledges that the right to purchase shares of
         Common Stock evidenced by this Agreement and any shares purchased
         under this Agreement 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)     Neither Participant nor any successor in interest of
         Participant will sell or otherwise transfer any Restricted Stock
         purchased under this Agreement in any way that might result in a
         violation of any federal or state securities laws or regulations.

         (c)     Perot Systems may require Participant or any subsequent holder
         of Restricted Stock purchased under this Agreement to provide Perot
         Systems, before any sale or other transfer of such shares, with such
         representations, commitments, and opinions regarding compliance with
         applicable securities laws and regulations as Perot Systems may deem
         necessary or advisable.

5.       Stock Certificates; Rights as Shareholder.

         Perot Systems will retain for safekeeping all certificates or other
         property representing Restricted Stock.  Each such certificate will
         bear such legends as the Board 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, but any and all
         stock and/or cash dividends (other than normal periodic cash
         dividends), distributions in property, or other distributions made on

                           PEROT SYSTEMS CORPORATION
              ADVISOR STOCK OPTION/RESTRICTED STOCK INCENTIVE PLAN

                   S T O C K  O P T I O N  A G R E E M E N T


THIS AGREEMENT, dated as of, ________, 1996, is by and between Perot Systems
Corporation, a Delaware corporation ("Perot Systems" or the "Company"), and
_______ ("Participant").

                                   WITNESSETH

WHEREAS, Perot Systems has adopted the Perot Systems Corporation Advisor Stock
Option/Restricted Stock Incentive Plan (the "Plan") to enable non-employee
directors and 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>   2
    (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 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, as determined in good faith by the Board of Directors of
           Perot Systems, as of the most recent June 30 or December 31 on or
           before the date of determination.

    (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 National Association of
    Securities Dealers Automated Quotation ("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.

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

    (b)    Perot Systems is not obligated to recognize any purported sale or
    other transfer of the option 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 unvested options evidenced by this Agreement will terminate and, except
    to the extent 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 member of the Perot Systems
    Board of Directors, a member of the Perot Systems Advisory Board, 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 thirty
    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 tradable,
    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
    tradable 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 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.





                                      -3-
<PAGE>   4
    (c)    The purchase price at which Perot Systems will purchase shares under
    its right of first refusal will be their fair market value, as determined
    in good faith by the Board of Directors of Perot Systems, as of the most
    recent June 30 or December 31 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 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





                                      -4-
<PAGE>   5
    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 l(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 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

                            STOCK PURCHASE AGREEMENT



         This Stock Purchase Agreement (this "Agreement") is dated as of August
20, 1992, between Perot Systems Corporation, a Texas corporation (the
"Company"), and Meyerson Family Limited Partnership, a Texas limited
partnership (the "Buyer").

         WHEREAS, the Company desires that the Company issue and sell to the
Buyer, and the Buyer desires to purchase from the Company, 2,000,000 shares of
the Company's Common Stock, $.O1 par value per share (the "Shares"), on the
terms and conditions set forth in this Agreement;

         NOW, THEREFORE, the Company and the Buyer hereby agree as follows:

         1.   Purchase and Sale of the Shares.

              (a)         Subject to the terms and conditions of this
         Agreement and based upon the representations contained herein, the
         Company hereby issues and sells the Shares to the Buyer and the Buyer
         hereby purchases the Shares from the Company.

              (b)         The Company hereby delivers to the Buyer a duly
         executed stock certificate representing all of the Shares.

              (c)         In full consideration for the purchase of the Shares,
         the Buyer agrees, concurrently with the issuance and transfer of the
         Shares, to pay or cause to be paid $3,000,000, payable by a wire
         transfer in federal or other same-day funds to the Company.

        2.    Representations of the Company.  The Company hereby represents to
the Buyer (which representations shall survive the purchase and sale hereunder)
as follows:

              (a)         The Company is a corporation duly organized, validly
         existing and in good standing under the laws of Texas.

              (b)         The execution, delivery and performance of this
         Agreement and the transactions contemplated hereby have been duly
         authorized by all necessary action on the part of the Company. This
         Agreement has been duly executed





                                      -1-
<PAGE>   2
         and delivered by the Company and constitutes the legal, valid and
         binding agreement of the Company, enforceable against it in accordance
         with its terms.

              (c)         The authorized capital stock of the Company consists
         solely of 20,000,000 shares of Common Stock, $.O1 par value per
         share, of which 3,930,380 shares were issued and outstanding as of
         July 31, 1992 and 8,000,000 shares  of Liquidation Preference Common
         Stock, par value $.O1 per share, of which 8,000,000 shares were issued
         and outstanding as of July 31, 1992, and 2,000,000 shares of Series A
         Preferred Stock, par value $4.25 per share, none of which shares are
         issued and outstanding.  Each of the issued and outstanding shares of
         Common Stock and Liquidation Preference Common Stock of the Company
         is, and upon issuance hereunder the Shares will be, validly issued,
         fully paid, and non-assessable and not issued in violation of the
         preemptive rights of any person.  Except for options granted pursuant
         to the Company's 1989 Pioneer Stock Option Plan and the Company's 1991
         Stock Option Plan, there are no outstanding options, warrants, or
         other rights or agreements obligating the Company to issue or sell any
         shares of its capital stock or securities convertible into its capital
         stock. To the best of the Company's knowledge, there are no voting
         trusts, voting agreements or other agreements or understandings with
         respect to the capital stock of the Company.

         3.   Representations of the Buyer.   The Buyer hereby represents to the
Company (which representations shall survive the purchase and sale hereunder)
as follows:

              (a)         The Buyer is a partnership duly formed and validly
         existing under the laws of the State of Texas.

              (b)         The execution, delivery and performance of this
         Agreement and the transactions contemplated hereby have been duly
         authorized by all necessary action on the part of the Buyer. This
         Agreement has been duly executed and delivered by the Buyer and
         constitutes a legal, valid and binding agreement of the Buyer,
         enforceable against it in accordance with its terms.

              (c)         The Buyer is acquiring the Shares for its own
         account for investment purposes and not with a view to the
         distribution thereof within the meaning of the Securities Act of 1933,
         as amended (the "Securities Act"), or applicable state securities
         laws.

              (d)         The Buyer represents that it has such knowledge and
         experience in financial and business matters as to be capable of
         evaluating the merits and risks of its





                                      -2-
<PAGE>   3
         investment in the Company, and has the ability to bear the economic
         risks of such investment. The Buyer further represents it has had
         access to information about the Company and it has had the opportunity
         to ask questions of, and to receive answers from, employees of the
         Company concerning the Company and that no information it has
         requested has been denied or withheld.

         4.   Compliance with Securities Laws.  The Buyer understands that the
offer and sale of the Shares acquired by it hereunder have not been registered
under the Securities Act or applicable state securities laws. The Buyer
understands that the Shares being acquired by it hereunder may not be sold,
transferred or otherwise disposed of without registration under the Securities
Act and applicable state securities laws, or the availability of an exemption
therefrom, and that in the absence of an effective registration statement or
the availability of such an exemption covering the offer and sale of the
Shares, that the Shares must be held indefinitely, and that the Buyer holding
same must bear the economic risks of such investment indefinitely. The Buyer
agrees that it will not sell or otherwise transfer any of the Shares in any way
that may result in a violation of any federal or state securities laws or
regulations. The certificates representing the Shares may bear appropriate
legends to such effect.

         5.   Covenants of the Company. The Company agrees to make cash 
payments to the Buyer or any person or entity affiliated or related to the
Buyer, including Morton H. Meyerson (the Buyer and each such person or entity
the "Taxpayer"), in the event that the Taxpayer owes federal income tax as a
result of the purchase of Shares contemplated by this Agreement, in an amount
equal to the lesser of (i) the amount of any tax (plus penalties and interest)
actually paid by Taxpayer in all years as a result thereof and as a result of
receiving the payment contemplated by this paragraph, and (ii) the amount of
tax savings (including interest) actually realized by the Company in all years
as a result thereof.  Each Taxpayer shall be an intended third-party
beneficiary of this Section 5.

         6.   Stock Repurchase.

              (a)   Subject to Section 6(e) below, if Morton H. Meyerson
         ("Meyerson") voluntarily resigns from his position as Chairman of the
         Board and Chief Executive Officer of the Company and if Meyerson and
         the Company do not reach a mutually agreeable arrangement for Meyerson
         to remain with the Company (collectively, the "Buyback Event"), the
         Company shall have the right to repurchase from the Buyer all or a
         portion of the Shares for the





                                      -3-
<PAGE>   4
         Buyback Amount (as defined below) or to receive from the Buyer cash in
         lieu thereof in the circumstances provided below (collectively, the
         "Buyback").

              (b)  Upon the occurrence of a Buyback Event, the Company shall
         have 30 days to give written notice (the "Buyback Notice") to the
         Buyer of the Company's decision to cause the Buyback.  The Buyback
         Notice shall state the number of shares of the Company's common stock
         that the Company desires to repurchase, but in no event shall such
         number exceed the Maximum Amount (as defined below).  Subject to
         Section 6(c) below, the Buyer shall then have 30 days to deliver to
         the Company stock certificates representing the number of shares of
         the Company's Common Stock equal to the number of shares set forth in
         the Buyback Notice in exchange for the payment by the Company to the
         Buyer of the Buyback Amount, with payment to be made by wire transfer
         of same-day funds.

              (c)  To the extent that the Buyer owns an insufficient
         number of shares to tender to the Company pursuant to a Buyback Notice
         required by Section 6(b) above or refuses to so tender such shares
         (such difference is referred to herein as the "Shortfall Amount"),
         then the Buyer shall tender to the Company so many of the number of
         shares actually owned by the Buyer in accordance with Section 6(b)
         above in exchange for payment by the Company in accordance with
         Section 6(b) above that it so wishes to tender, and the Buyer shall be
         obligated to pay to the Company, within one year after the date of the
         Buyback Event, cash in an amount equal to the Fair Market Value (as
         defined below) of the number of shares represented by the Shortfall
         Amount less the Buyback Amount for such number of shares represented
         by the Shortfall Amount, provided that interest required to be paid
         pursuant to the Buyback Amount shall be computed not to the date of
         the Buyback Event but instead to the date of the cash payment
         required to be made by the Buyer pursuant to this Section 6(c).

              (d)  For purposes of this Section 6, the following terms shall 
         be defined as set forth below:

                   (i)         "Buyback Amount" means the product of (i) the
              number of shares of the Company's Common Stock actually tendered
              by the Buyer to the Company pursuant to the Buyback and (ii) the
              sum of $1.50 and interest on such $1.50 at an interest rate of 
              6.5% per annum, compounded annually, and computed from the date 
              of this Agreement to the date of the Buyback.

<PAGE>   5
                   (ii)        "Maximum Amount" means a number of shares of
              the Company's common stock equal to the product of 2,000,000
              and

              <S>              <C>
              |        x  |    Where x equals the number of full months that Meyerson remains
              | 1 -  ---- |    as Chairman of the Board and Chief Executive Officer of the Company,
              |       60  |    commencing June 1, 1992,

</TABLE>

              but in the event the Maximum Amount shall be less than 0, then
              the Maximum Amount shall be deemed to be 0.

                   (iii)       "Fair Market Value" means an amount
              representing the value of a number of shares of the Company's
              Common Stock as mutually agreed upon by the Company and the
              Buyer; but if they cannot agree within 60 days prior to the
              date requiring payment of such amount, then each of the
              Company and the Buyer shall select an independent,
              third-party, reputable appraiser, and the two appraisers shall
              select a third independent, third-party, reputable appraiser
              who shall make a determination as to such value, and the
              determination of such third appraiser shall be binding on the
              Company and the Buyer. In making a determination, the third

                   (iii)       Meyerson is constructively terminated from

              Meyerson;

                   (vi)        the Company, its Board of Directors, or one
              of the Company's officers requests Meyerson to engage in any

                   (vii)       the Board of Directors of the Company makes
              a major change in corporate policy or has decided that the
              Company should engage in a significant corporate development
              or transaction and Meyerson has voted against such decision or
              Meyerson is not present at the meeting where the decision is
              made; provided that (a) Meyerson 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 Meyerson is not

              Board of Directors to approve a policy, development or
              transaction recommended by Meyerson.

              (f)         Morton H. Meyerson hereby agrees that, to the extent

         to Section 6(c) hereof, Morton H. Meyerson will be liable for, and
         agrees to pay to the Company, any deficiency in the amount to be paid

         Obligations").  Morton H. Meyerson also waives all demands and notices
         of every kind in connection with the Guaranteed Obligations and this
         guarantee, including without limitation notice of acceptance of this
         guarantee and notice of the occurrence of any breach or default by

         Morton H. Meyerson further waives diligence, presentment, protest and
         suit on the part of Company.  This guarantee is a primary,
         unconditional guarantee of payment and performance and not a guarantee
         of collection.  The guarantee is not subject to any counterclaim,
         setoff, deduction, reduction or other defense for any reason
         whatsoever.

              (g)          Except as provided in subsection 6(f) with respect
         to Morton H. Meyerson, the obligations of the Buyer under this Section
         6 shall be non-recourse to the partners of the Buyer.

7.       Registration Rights.

              (a)         Subject to Section 7(i) below, if the Company
         proposes to register for sale for cash in an offering to the public
         any shares of its stock ("Stock") under the Securities Act on Form
         S-1, S-2, or S-3, or any successor registration form at the time in
         effect, it will at such time give written notice to the Holders (as
         defined below) of its intention to do so. Upon written request of the
         Holder, given within fifteen days after the giving of any such notice
         by the Company, the Company will use its best efforts to cause the
         shares of Stock acquired hereby held by the respective Holders for
         which registration is requested (the "Piggy-Back Registrable Shares")
         (the "Requesting Holders") to be registered under the Securities Act
         as part of the offering being made by the Company and under the same
         registration statement proposed to be filed by the Company; provided,
         however, if the offering to which the proposed registration statement
         relates is to be distributed by or through an underwriter approved by
         the Company, the Requesting Holders shall agree to sell the Piggy-Back
         Registrable Shares through such underwriter on the same terms and
         conditions as the under-writer agrees to sell the other securities;
         and provided further, that the Company shall not be required to
         include part or all of the Piggy-Back Registrable Shares if the
         Company is advised in writing by the managing underwriter for the
         proposed offering that the inclusion of such Piggy-Back Registrable
         Shares together with the Stock requested to be registered by other
         owners (the "Other Owners") of shares of Stock (the "Other Registrable
         Shares") pursuant to agreements between such Other Owners and the
         Company which contain registration rights comparable to those
         contained herein (the Piggy-Back Registrable Shares and the Other
         Registrable Shares are sometimes hereinafter referred to as the
         "Aggregate Registrable Shares") would in its opinion have a material
         adverse effect on such proposed offering. In such event, the Company
         shall include in the proposed offering that number of Piggy-Back
         Registrable Shares equal to the Requesting





                                      -7-
<PAGE>   8
         Holders, pro rata portion of the total number of Aggregate Registrable
         Shares which may be registered in the opinion of the managing
         underwriter referred to in the preceding sentence.  The term "Holder"
         means the Buyer or any Related Party of the Buyer, but only during the
         period or periods of time any of such persons or entities own stock
         which may qualify as "Piggy-Back Registrable Shares".  The term
         "Related Party" means any limited partner of the Buyer, Morton H.
         Meyerson and Marlene Meyerson, the parents of Morton H. Meyerson and
         the mother of Marlene Meyerson (cumulatively, the "Parents"), any
         descendants of the Parents, any trust which includes as a beneficiary
         any of the persons or entities above and any corporation, partnership
         or other entity of which a majority of the voting shares or equity
         interest is controlled directly or indirectly by any of the
         above-mentioned persons or entities, to the extent such persons or
         entities continue to so control such corporation, partnership or other
         entity.

              (b)          Notwithstanding anything to the contrary contained
         in Section 7(a) hereof, the Company shall have no obligation to
         register the Piggy-Back Registrable Shares if, within twenty days from
         the receipt of a request to register the Piggy-Back Registrable Shares
         pursuant to Section 7(a) hereof, the Company shall have delivered to
         the Buyer an opinion of experienced securities counsel for the Company
         to the effect that no registration of the Piggy-Back Registrable
         Shares is required for their sale on the terms on which the Requesting
         Holder desires to sell those shares.

              (c)          The Requesting Holders and the Company shall in
         connection with any registration of any Piggy-Back Registrable
         Shares contemplated by this Section 7 enter into an appropriate
         underwriting agreement containing terms and provisions (including
         reasonable provisions as to opinions of counsel, comfort letters and
         indemnification) customary in such agreements.

              (d)          The Company shall prepare and file with the
         Securities and Exchange Commission all amendments, post-effective
         amendments and supplements to a registration statement containing any
         Piggy-Back Registrable Shares pursuant to Section 7(a) hereof as may
         be necessary under the Securities Act and the regulations of the
         Securities and Exchange Commission to permit the sale of such
         Piggy-Back Registrable Shares to the public.

              (e)          The Company shall use its best efforts to register
         or qualify the Piggy-Back Registrable Shares covered by a registration
         statement filed pursuant to





                                      -8-
<PAGE>   9
         Section 7(a) hereof under blue sky or other state securities laws, in
         such states or jurisdictions as shall reasonably be requested by the
         Requesting Holders, and do any and all other reasonable acts or things
         which may be necessary to enable the Requesting Holders to consummate
         the public sale or other disposition of Registrable Shares in such
         jurisdictions; provided, however, that the Company shall not be
         obligated to qualify as a foreign corporation to do business under the
         laws of any jurisdiction in which it is not then qualified or to file
         any general consent to service of process.

              (f)         The Company will bear all expenses related to a
         registration pursuant to this Section 7, except for amounts reflecting
         the increase in expenses directly attributable to the inclusion of the
         portion of the Piggy-Back Registrable Shares so registered, which
         increase in expenses shall be borne by the appropriate Requesting
         Holder. In connection with any registration undertaken by the Company
         hereunder, the Company and the Requesting Holders shall indemnify each
         other against violations of law in customary form and shall execute
         such other agreements in connection with the underwriting as shall
         reasonably be requested by the Company.

              (g)         The Requesting Holders shall promptly furnish the
         Company, upon request, with all information required in the opinion of
         the Company's securities counsel to be included in the registration
         statement, or any amendment or supplement thereto.

              (h)         The Holder's rights and obligations pursuant to this
         Section 7 may be exercised only by the Holders.

              (i)         Notwithstanding anything to, the contrary in this
         Section 7, for a registration of the Company's Stock in an initial
         public offering, the, Holders shall not have any right to request the
         Company to register any Piggy-Back Registrable Shares unless the
         Company is registering Stock held by owners other than the Company as
         a part of such offering.

         NOW, THEREFORE, in consideration of good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, PSC hereby agrees
for the benefit of Cannavino as follows:

         than Good Reason (as defined in the Employment Agreement) in which
         case it will mean the twelfth anniversary of the Effective Date or
         (ii) if Cannavino ceases to be an employee of PSC for any reason and

         by an independent appraiser (the costs of which will be paid by PSC)
         selected jointly by PSC and Cannavino.  If an independent appraisal is
         necessary, PSC and Cannavino will negotiate in good faith to agree on
         the appraiser within 30 days.  If they cannot agree, the appraiser
         will be selected by an independent arbitrator selected pursuant to the
         rules of the American Arbitration Association.  The appraiser will
         make its determination within 60 days after selection.

         upon the exercise of this Option, together with any successor
         security, property or cash issued or distributed by PSC or any
         successor entity, whether by way of merger, consolidation, share
         exchange, reorganization, liquidation, recapitalization or otherwise.

                 (l)      "Transfer" or "transfer" or derivations thereof
         include any sale, assignment, gift, pledge, encumbrance,
         hypothecation, mortgage, exchange or any other disposition.

                 (m)      "Unvested Stock" means all shares of Restricted Stock
         other than Vested Stock.

                 (n)      "Valuation Date" means each June 30 and December 31
         of every year, and any other date as of which the Board determines the
         Market Value of Restricted Stock.

         that have vested to Cannavino or Cannavino's estate pursuant to
         Section 3.

                 (p)      "Vesting Date" means each date upon which shares of
         Restricted Stock vest to Cannavino or Cannavino's estate pursuant to
         this Grant, as set forth in Exhibit B hereto.

                 (q)      "Vesting Period" means the period of time commencing
         on the date of this Grant and ending on the last date on which
         Restricted Stock vests hereunder.

         2.      Grant of Option; Exercise.

                 (a)      Subject to the terms, conditions and restrictions set
         forth in this Grant, PSC hereby grants to Cannavino the option to
         purchase from PSC 1,000,000 shares of Common Stock, at an exercise
         price of $2.00 per share.  PSC is granting the Option hereunder in
         consideration for Cannavino's agreement not to commence permanent,
         full-time employment with any other company before January 1, 1996.

                 (b)      Subject to the terms, conditions and restrictions set
         forth in this Grant, Cannavino may exercise the Option at any time
         after the Effective Date and prior to the Expiration Date.  If
         Cannavino does not accept employment with PSC pursuant to the
         Employment Agreement by December 31, 1995, then the Option will be
         canceled and have no further effect.

                 (c)      To the extent that Cannavino exercises the Option, in
         whole or in part, on or prior to December 31, 1995, the exercise price
         may be paid 30% in cash and 70% by delivery from Cannavino to PSC of a
         secured promissory note substantially in the form of Exhibit C hereto
         (the "Purchase Price Note"), which will be secured by a pledge of this
         Option and any Restricted Stock acquired hereunder pursuant to a
         pledge agreement substantially in the form of Exhibit F hereto (the
         "Pledge Agreement").  To the extent that Cannavino exercises the
         Option, in whole or in part, after December 31, 1995, the full
         exercise price payable upon each exercise must be paid by Cannavino to
         PSC at the time of exercise.

         3.      Vesting of Restricted Stock.  The Restricted Stock issuable
upon exercise of the Option will vest in Cannavino in accordance with the
Vesting Schedule set forth on Exhibit B hereto, but only for so long as
Cannavino is an employee of PSC, except as follows:

                 (a)      If Cannavino's employment with PSC is terminated (i)
         by PSC without Cause, including termination due to Cannavino's
         physical or mental illness or death, or (ii) by Cannavino with Good
         Reason, then (A) the Restricted Stock scheduled to vest on each
         Vesting Date to and including the Vesting Date in 1998 will vest on
         such Vesting Dates (to the extent not previously vested)
         notwithstanding such termination and (B) if such termination occurs
         after the Vesting Date in 1998, the Restricted Stock scheduled to vest
         on the next Vesting Date after such termination (if any) will vest on
         such Vesting Date notwithstanding such termination.  Notwithstanding
         the foregoing, if vesting is accelerated under Section 3(b), then
         Section 3(b) (and not this paragraph) will apply through the last
         Vesting Date for which vesting is accelerated under Section 3(b) and,
         thereafter, this paragraph will again apply.

                 (b)      If a Change in Control (as defined in the Employment
         Agreement) occurs while Cannavino is employed by PSC, or if
         Cannavino's employment with PSC is terminated prior to but in
         connection with a Change in Control, then (A) the Restricted Stock
         scheduled to vest on each Vesting Date to and including the Vesting
         Date in 2000 will vest immediately upon such Change in Control (to the
         extent not previously vested) and (B) if the Change in Control occurs
         after the Vesting Date in 1999, the Restricted Stock scheduled to vest
         on the next two Vesting Dates after such termination (if any) will
         vest immediately upon such Change in Control.  If the vesting
         scheduled to occur on one or more Vesting Dates is accelerated
         pursuant to this paragraph, then the remaining Vesting Dates, which
         are not accelerated, will remain unchanged, with the result that no
         vesting will occur during the years for which vesting was accelerated.





                                     Page 3
<PAGE>   4
                 (c)      If Cannavino is employed by PSC pursuant to the
         Employment Agreement by December 31, 1995, but his employment with PSC
         is terminated prior to the Vesting Date in 1996 (i) by PSC with Cause
         or (ii) by Cannavino without Good Reason, then the Restricted Stock
         scheduled to vest on the Vesting Date in 1996 will vest on such
         Vesting Date notwithstanding such termination.

         4.      Restrictions on Transfer.  The following restrictions on
transfer apply unless PSC otherwise agrees in writing:

                 (a)      The Option may not be sold or otherwise transferred,
         except by will or the laws of descent and distribution.  If the Option
         is transferred by will or the laws of descent and distribution, the
         transferee will hold the Option and any Restricted Stock acquired upon
         exercise of the Option subject to all of the vesting provisions,
         transfer restrictions, repurchase options and other provisions of this
         Grant and the Pledge Agreement, in each case as if such Option or
         Restricted Stock continued to be held by Cannavino.  Without limiting
         the generality of the foregoing, a transferee under this paragraph
         will hold the Option and any Restricted Stock subject to PSC's
         repurchase options and other rights under Section 5, Section 6 and
         paragraphs (b), (c) and (d) of Section 7 and PSC's rights of offset
         under Section 13.

                 (b)      Shares of Unvested Stock may not be sold or otherwise
         transferred.

                 (c)      One-half of the total number of shares of Vested
         Stock that vest on a particular Vesting Date may not be sold or
         otherwise transferred for two years after such Vesting Date; provided
         that such restriction on transfer will not apply (i) if Cannavino
         sells Vested Stock and applies the proceeds of such sale, less any
         federal income taxes incurred by Cannavino as a result of such sale,
         to prepayment of the Notes (as defined in Section 12), or (ii) if
         Cannavino's employment with PSC terminates for any reason.

                 (d)      Shares of Vested Stock may not be sold or otherwise
         transferred prior to the Restricted Stock being Publicly Traded unless
         the holder has given PSC any notice required under Section 5 and PSC
         has waived in writing any right it has to buy back the shares under
         Section 5.

                 (e)      Notwithstanding the foregoing restrictions on
         transfer, Cannavino may transfer, while he is alive or as a
         distribution upon his death, all or a portion of the Restricted Stock
         to a maximum of two transferees, but only if each transferee is
         Cannavino's spouse, descendant or a trust for their benefit.  Any such
         transfer must be effected pursuant to documentation reasonably
         acceptable in form and substance to PSC, and such documentation must
         provide that the Restricted Stock transferred remains subject to all
         of the vesting provisions, transfer restrictions, repurchase options
         and other provisions of this Grant and the Pledge Agreement, in each
         case as if such Restricted Stock continued to be held by Cannavino.
         Without limiting the generality of the foregoing, a transferee under
         this paragraph will hold the Restricted Stock subject to PSC's
         repurchase options and other rights under Section 5, Section 6 and
         Section 7 and PSC's rights of offset under Section 13.

         PSC is not obligated to recognize any purported sale or other transfer
of the Option or any Restricted Stock in violation of this Section 4 and,
unless it elects to do otherwise, may treat any such purported sale or transfer
as null, void and of no effect.





                                     Page 4
<PAGE>   5
         5.      First Option to Buy Restricted Stock.  At any time before the
Restricted Stock is Publicly Traded, if Cannavino desires or is obligated to
sell or otherwise transfer any Vested Stock (including any distribution to
heirs or other beneficiaries of Cannavino's estate, but excluding any transfer
pursuant to Section 4(e) or Section 9), Cannavino is required to give PSC
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, PSC will have the right to buy back such Restricted Stock for cash
at a purchase price equal to its Market Value.

         6.      Option to Buy Unvested Stock.  If Cannavino's employment with
PSC is terminated for any reason during the Vesting Period, then (a) the Option
will be immediately canceled with respect to any shares of Unvested Stock,
except for Unvested Stock that will vest at or following such termination
pursuant to Section 3, and (b) PSC will be entitled, by notice to Cannavino
within 150 days after such termination, to require Cannavino to sell to PSC all
or any part of the Unvested Stock then held by Cannavino, except for any
Unvested Stock that will vest at or following such termination pursuant to
Section 3.  The purchase price applicable to PSC's purchase option under clause
(b) above will be (i) the After-Tax Cost of such Unvested Stock, if Cannavino's
employment with PSC is terminated by PSC without Cause or by Cannavino with
Good Reason, or (ii) the Cost of such Unvested Stock, if Cannavino's employment
with PSC is terminated by PSC with Cause or by Cannavino without Good Reason.

         7.      Competition.  If, following Cannavino's employment by PSC
pursuant to the Employment Agreement, Cannavino breaches Section 4 of the
Employment Agreement and such breach is not cured in accordance with the notice
and cure provisions of Section 5 of the Employment Agreement (either because
Cannavino fails to give notice of the action constituting a breach within the
time period specified therein or because he fails to effect the cure required
thereunder within the specified time period), then PSC will have the right, for
150 days after PSC discovers such breach, to

                 (a)      cancel any unexercised portion of the Option;

                 (b)      cancel any remaining vesting that has not yet
         occurred, but is scheduled to occur in the future under Section 3;

                 (c)      require Cannavino to sell to PSC all or any part of
         the Restricted Stock then owned by Cannavino at a purchase price equal
         to its After-Tax Cost; and

                 (d)      if any shares of Restricted Stock have been sold or
         otherwise transferred by Cannavino (including any shares sold to PSC
         but excluding any shares transferred under Section 4(e) or acquired by
         a transferee under Section 4(a), which shares will be held subject to
         this paragraph) prior to such time, require Cannavino to pay to PSC,
         with respect to each share of Restricted Stock not then held by
         Cannavino, an amount in cash equal to the value of the consideration
         received by Cannavino for such share or, if such share was not
         transferred in a bona fide arm's length sale, the greater of the value
         of such consideration or the Market Value of such share on the date of
         such transfer, less (in either case) the After-Tax Cost of such share;

provided that (i) the total number of shares of Restricted Stock as to which
the Option is canceled pursuant to clause (a) that are vested on the date of
cancellation or would vest subsequent to such date pursuant to Section 3, plus
(ii) the total number of shares of Restricted Stock as to which future vesting
is canceled pursuant to clause (b), plus (iii) the total number of shares of
Restricted Stock that are repurchased by PSC pursuant to clause (c), plus (iv)
the total number of shares of Restricted Stock with





                                     Page 5
<PAGE>   6
respect to which Cannavino is required to make the payment described in clause
(d), may not exceed 200,000 shares (as adjusted to reflect any stock split,
stock dividend or similar event affecting the total number of shares of Common
Stock outstanding).  PSC will exercise its remedies under this Section 7 in the
order of paragraphs (a) through (d), above, until the 200,000 share limit is
reached.

         8.      Procedure for Repurchase of Stock.  Whenever PSC has a right
to buy back shares of Restricted Stock under Section 5, 6 or 7, PSC may
exercise its right by notifying Cannavino of PSC's election to exercise its
right within the designated exercise period.  The giving of such notice will
give rise to an obligation on the part of Cannavino to tender to PSC, within 10
days, any previously issued certificate representing shares of Restricted 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, PSC may cancel any outstanding certificate representing shares
to be bought back.  PSC is required to tender the purchase price for shares to
be bought back under this Section 8 within 20 days of giving notice of its
election to exercise its right to buy back shares.  If Cannavino has not
complied with an obligation to return a certificate representing shares to be
bought back, however, PSC 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.

         9.      Put Option.  If the Restricted Stock is not Publicly Traded by
the fifteenth anniversary of the Effective Date (the "Put Date"), then,
beginning on the Put Date and ending on the date that the Restricted Stock is
Publicly Traded, Cannavino will have the option (the "Put Option") to require
PSC to repurchase and exchange Vested Stock at its Put Value, on the terms set
forth in this Section 9. but such exercise will be limited to a number of
shares of Vested Stock equal to the shares resulting in profits to Cannavino
(calculated as the Put Value, less any federal income taxes incurred by
Cannavino as a result of such sale or exchange) equal to no more than all the
then outstanding principal and interest under the Notes, provided that
Cannavino will transfer and exchange such Vested Stock to PSC, at the Put
Value, equal to such outstanding principal and interest under the Notes in
exchange for cancellation of such principal and interest, and will only receive
from PSC cash equal to the amount necessary to pay any federal income taxes
incurred by Cannavino as a result of such sale or exchange.

The Put Option may be exercised no more than once.  The Put Option may be
exercised only by Cannavino with respect to shares of Vested Stock that he owns
(or shares that are held by a transferee under Section 4(e) before or after
Cannavino's death by the holders of such shares, proportionate to their
holdings).  Cannavino may exercise the Put Option by notifying PSC of his
election to exercise and the number of shares to be sold (up to the maximum as
permitted under the Put above), and upon delivery of such notice the parties
will determine the Put Value (in accordance with Section 1(j)).  The purchase
and sale of shares pursuant to the Put Option will occur at a closing to be
held 30 days after the determination of the Put Value (or such earlier date as
may be mutually agreed).  At the closing, Cannavino will deliver to PSC all
certificates representing shares of Vested Stock to be sold to PSC, duly
endorsed in blank or having a duly executed stock power attached in proper form
for transfer, and PSC will cancel the indebtedness exchanged for such shares
and deliver the purchase price so much of the Vested Stock as is put to PSC to
permit Cannavino to pay any income taxes associated with the Put.
Alternatively, if Cannavino so elects in his notice of exercise, he may
exercise the Option (subject to the vesting and other provisions of this Grant)
at the closing and simultaneously sell Restricted Stock acquired upon exercise
to PSC pursuant to the Put Option, in which case PSC may deduct the applicable
exercise price from the amount to be paid to Cannavino for such taxes (after
deduction for the canceled Notes); provided however in such case the number of
shares of Vested Stock which may be exercised by the Put Option shall include
shares to also cover the expense of the exercise price.





                                     Page 6
<PAGE>   7
Notwithstanding the foregoing, if, prior to the Put Date and prior to the time
that the Restricted Stock is Publicly Traded, Cannavino incurs liability for an
excise tax under Section 4999 of the Code, without regard to the effect of this
Section 9, then Cannavino may additionally exercise the Put Option (which
shares will not be considered with regard to the above Put) beginning on the
date that Cannavino incurs such excise tax liability, but such exercise will be
limited to a number of shares of Vested Stock equal to the lesser of (a) shares
resulting in aggregate net profits to Cannavino (calculated as the Put Value,
less Cannavino's tax basis in such shares, less any federal income taxes
incurred by Cannavino as a result of such sale, less any portion of the sale
proceeds that is required to be applied to the Purchase Price Note) equal to
Cannavino's excise tax liability and (b) during any 12 month period, one
quarter of the total number of shares that have previously vested.

         10.     Defense of Certain Claims.  If (a) Cannavino accepts
employment pursuant to the Employment Agreement by December 31, 1995, and (b)
International Business Machines Corporation ("IBM") asserts a claim against
Cannavino, based on his association with PSC prior to the Effective Date,
seeking a refund of any profits realized by Cannavino from the exercise during
March, April or May of 1995 of stock options granted by IBM, which profits
would not be subject to any claim by IBM if Cannavino had no contact with PSC
prior to the Effective Date, regardless of any conduct of Cannavino after the
Effective Date (a "Covered Claim"), then (i) PSC will pay all reasonable costs
associated with contesting the Covered Claim, but only if and for so long as
Cannavino's defense against the Covered Claim has merit, as determined in good
faith by PSC, and only if PSC consents in advance to the selection of
Cannavino's attorneys (which consent will not be unreasonably withheld), and
(ii) PSC will loan to Cannavino any amount that Cannavino is required to pay to
his former employer in respect of a Covered Claim (whether pursuant to a
judgment or in settlement), up to an aggregate of $2,700,000, pursuant to a
promissory note in the form of Exhibit D hereto (the "Covered Claims Note"),
which will be secured by the Pledge Agreement.  The Covered Claims specifically
exclude any claim relating to activities by Cannavino subsequent to his
employment by PSC.  In the course of defending himself against a Covered Claim,
Cannavino may also defend himself against other claims that are based on the
same facts as the Covered Claim, in which case Cannavino will be responsible
only for those non-incidental costs that would not have been incurred if his
defense was limited solely to the Covered Claim (subject to the limitations in
clause (i) above).  PSC will not be required to advance any funds under the
Covered Claims Note after Cannavino's death or after the date on which the
Covered Claims Note would be due in accordance with its terms.  PSC hereby
consents to the selection of Proskauer Rose Goetz & Mendelsohn LLP as
Cannavino's attorney (for purposes of clause (i) above) if the fees charged by
such firm are reasonable.

         11.     General Advance.  At the request of Cannavino at any time
prior to August 15, 1996, PSC will loan Cannavino up to $1,500,000 pursuant to
a promissory note substantially in the form of Exhibit E hereto (the "General
Note"), which will be secured by the Pledge Agreement.  Such loan will be made
in a single advance, and any portion of such loan that is repaid by Cannavino
may not be reborrowed.  Cannavino may use the proceeds of such loan for any
purpose, including without limitation purchasing a house or furnishings for a
house or for other personal expenditures.  PSC will not be required to advance
any funds under the General Note after Cannavino's death or after the date on
which the General Note would be due in accordance with its terms.

         12.     Tax Matters.  PSC agrees to indemnify Cannavino from any
liability for federal income taxes that Cannavino may incur as a result of any
finding that the interest rate on the Purchase Price Note, the General Note or
the Covered Claims Note (collectively, the "Notes"), if any such Notes are
issued, is below the minimum interest rate respected for tax purposes under
applicable federal law.  Such indemnification payments will be "grossed up" as
necessary to compensate Cannavino for any additional





                                     Page 7
<PAGE>   8
federal income tax liability incurred as a result of such indemnification
payments and any "gross up" payment.

         13.     Rights of Offset.  PSC may, in its discretion, satisfy any
payment obligations to Cannavino under this Grant by offset against amounts
owing from Cannavino to PSC under any of the Notes, whether or not such amounts
are then due and payable under the Notes; provided that PSC must pay in cash
(a) defense costs for Covered Claims to the extent required under Section
10(i), (b) indemnity payments to the extent required under Section 12 and (c)
the initial advances required in respect of the Notes.  Cannavino may, in his
discretion, satisfy any payment obligation to PSC under the Notes by offset
against amounts then owing from PSC to Cannavino under this Grant.

         14.     Compliance with Securities Laws.  Exercise of the Option may,
in PSC's discretion, be conditioned upon a representation by the Option holder
that he is an "accredited investor" within the meaning of Regulation D under
the Securities Act of 1933, as amended (the "Securities Act"), and that he is
acquiring the Restricted Stock for his own account and not with a view to any
resale or distribution thereof.  Neither Cannavino nor any subsequent holder of
the Restricted Stock may sell or otherwise transfer any Restricted Stock in any
way that may result in a violation of any federal or state securities laws or
regulations.  PSC may require any subsequent purchaser or other transferee of
Restricted Stock that cannot be publicly traded to provide PSC, prior to such
sale or other transfer, with such representations, commitments and opinions
regarding compliance with applicable securities laws and regulations as PSC may
deem necessary or advisable.  PSC is granting the Option and will offer and
sell the Restricted Stock hereunder pursuant to an exemption from the
registration requirements of the Securities Act provided by Section 4(2)
thereof, and under similar provisions of state securities laws (and not under
Rule 701 under the Securities Act).

         15.     Stock Certificates; Rights as Shareholder.  PSC will retain
for safekeeping all certificates representing Unvested Stock and, until all
obligations under the Notes have been repaid in full, all other Restricted
Stock.  Each certificate evidencing Restricted Stock will bear such legends as
PSC determines are necessary or appropriate.  Whether or not certificates
representing shares of Restricted Stock have been issued or delivered,
Cannavino will have all the rights of a shareholder of Restricted Stock,
including voting, dividend and distribution rights, with respect to shares of
Restricted Stock owned by Cannavino, subject to PSC's repurchase rights
hereunder.  Cannavino will not have any rights as a shareholder with respect to
any shares subject to the Option before the date of exercise of the Option with
respect to such shares.

         16.     Income Tax Withholding.  Cannavino shall, upon request by PSC,
reimburse PSC for, or PSC may withhold from sums or property otherwise due or
payable to Cannavino, any amounts PSC is required to remit to applicable taxing
authorities as withholding pursuant to any law or government regulation or
ruling.  If shares of Restricted Stock are withheld for such purpose, they will
be withheld at Market Value.  If Cannavino fails to reimburse PSC for any such
amount within 30 days after PSC requests reimbursement in writing, PSC has the
right to recover that amount by selling or canceling sufficient shares of any
Restricted Stock held by Cannavino.

         17.     Adjustments.  If any change is made in the shares of Common
Stock (including without limitation by stock dividend, stock split, merger or
consolidation, but not including the issuance of additional shares for
consideration or the issuance of restricted stock to employees, consultants or
other agents of PSC), the Board 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 acquired by Cannavino

upon exercise of the Option and the exercise price applicable thereto as are
equitable to preserve the intent and economic effect of this Grant.

         18.     Action by PSC.  Any election, consent, waiver or other action

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (the "Agreement") is made as of September
16, 1995 (the "Effective Date") by and between Perot Systems Corporation, a
Texas corporation ("PSC"), and James A. Cannavino ("Cannavino").

         1.      Employment.  Subject to the terms and conditions specified in
this Agreement, PSC hereby agrees to employ Cannavino as President and Chief
Operating Officer and Cannavino agrees to perform those duties normally
associated with such positions, subject to such legal and ethical policies and
guidelines as may be reasonably established from time to time by the Board of
Directors of PSC (the "Board"), the Chairman of the Board (the "Chairman") or
the Chief Executive Officer of PSC.  The term of Cannavino's employment by PSC
hereunder will commence on the Effective Date and will continue thereafter
until terminated in accordance with Section 8.

         2.      Extent of Services.  Cannavino will not participate in any way
in any other job or business while employed by PSC, without prior written
consent of the Board; provided that Cannavino may (subject to Section 4) engage
in charitable activities, passive investments and part time business projects
or ventures unrelated to the business of PSC if such activities (taken
together) do not occupy a significant portion of Cannavino's business time and
do not materially interfere with the performance of his duties to PSC.  At the
request of the Board, Cannavino will serve as a director and/or officer of one
or more of PSC's subsidiaries for no additional compensation.

         3.      Confidential Information.  Cannavino agrees never to use or
disclose any Confidential Information of PSC, except for (a) use and disclosure
made in good faith by Cannavino in the course of his services for PSC and (b)
disclosure required by applicable law.  "Confidential Information" of PSC
includes all PSC trade secrets, intellectual property or other business,
financial or technical information relating to PSC's business, technology,
vendors or customers, whether or not reduced to writing and whether or not
conceived, originated, discovered or developed in whole or in part by
Cannavino; provided that Confidential Information does not include (i)
information that is available to the general public or known generally within
the industry; (ii) information that has been intentionally disclosed by PSC to
a third party without any confidentiality obligation on the part of the third
party; and (iii) information that was known to Cannavino prior to his
association with PSC.  Cannavino will also comply with any agreements by PSC to
protect third party confidential information, to the same extent as if it were
Confidential Information of PSC hereunder.

         4.      Competition.  Cannavino acknowledges that, in the course and
as a result of his employment with PSC, Cannavino will obtain special training
and knowledge and will come in contact with PSC's customers and potential
customers, which training, knowledge and contacts would provide invaluable
benefits to competitors of PSC.  Accordingly, and in consideration of PSC's
agreement to hire Cannavino hereunder, which Cannavino acknowledges is
conditioned on the covenants contained herein, Cannavino agrees that, during
the time Cannavino is employed by PSC and within two years thereafter, except
with the prior written consent of PSC, Cannavino will comply with the following
covenants:


<PAGE>   2
                 (a)      Cannavino will not, directly or indirectly, whether
         as an employee, employer, consultant, agent, principal, partner,
         owner, shareholder (other than as a holder of less than 5% of a
         publicly traded class of securities), officer, director or in any
         other individual or representative capacity, provide services to, or
         be otherwise associated with, any of the companies or divisions listed
         on Schedule I attached hereto (the "Named Competitors"); provided that
         Cannavino may serve as a senior management level employee or
         consultant for, or be a shareholder or director of, the parent company
         or an affiliate of a Named Competitor, if he is not involved in the
         day-to-day activities of the Named Competitor and the revenues of the
         Named Competitor during its most recent fiscal year at the time
         Cannavino begins such employment are less than 20% of the consolidated
         revenues of the parent company and its subsidiaries.  Within 30 days
         after Cannavino's employment with the Company is terminated, PSC may
         add up to six additional Named Competitors to the list set forth on
         Schedule I, if each new Named Competitor's principal business is
         directly competitive with a Core Business of PSC.  "Core Business"
         means a business segment (based on the type of products or services
         provided and not the industry to which such products or services are
         provided) that generated 20% or more of PSC's total revenues during
         the latest completed fiscal year of PSC prior to Cannavino's
         termination.

                 (b)      Cannavino will not head up, run, consult for or
         become an employee of any entity whose principal business is directly
         competitive with a Core Business of PSC, or any subsidiary or division
         of a company where the principal business of such subsidiary or
         division is directly competitive with a Core Business of PSC.

                 (c)      Cannavino will not directly solicit to work for him
         or any entity by which is he employed or intends to become employed
         (and actually is employed within six months), or specifically identify
         for employment by any such entity, any individuals who, at the time of
         such solicitation or identification, are employees of PSC; provided
         that (i) no violation of this paragraph will be deemed to have
         occurred unless the employee involved actually commences employment
         with such entity and (ii) Cannavino may solicit or identify for
         employment up to three such individuals, if such individuals were
         first employed by PSC after the Effective Date.

                 (d)      Cannavino will not directly solicit from a Major
         Customer any  business that  is  directly competitive with  a Core
         Business of PSC or directly  competitive with a business that
         accounts for more than 25% of PSC's revenues from such Major Customer
         in the year prior to Cannavino's  termination.  For  such purposes, a
         "Major Customer" means any  customer (which is limited to the
         operating unit that benefits  from the  goods  or services  provided
         by PSC and, if  such  operating  unit has  a  parent  company, the
         other operating units of such  parent company that  do not  receive
         any substantial benefits from such goods or services will not be Major
         Customers) that accounted for more than $5 million in revenues to PSC
         during PSC's latest completed fiscal year prior to  Cannavino's
         termination,  adjusted to  an annualized basis for  any contracts
         entered into during such fiscal year, or which would  account for more
         than $5 million in revenues to PSC during the fiscal year in which
         Cannavino is terminated after giving





                                   Page 2
<PAGE>   3
         effect to any new contracts entered into during such fiscal year;
         provided that (i) no more than 50 customers may be classified as Major
         Customers and (ii) within 30 days after Cannavino's termination, PSC
         will provide to Cannavino a list of its Major Customers at such time,
         indicating any Major Customers to whom PSC provides goods or services
         in excess of such 25% of revenue for such Major Customer that do not
         constitute Core Business and indicating such goods or services.  It is
         understood that Cannavino may attend meetings and social events with
         executives of a Major Customer (or the parent of a Major Customer)
         without violating this paragraph, so long as he does not directly
         solicit any business of the type described in the first sentence of
         this paragraph from such Major Customer.

         The foregoing restrictions will not apply to the ownership by
Cannavino of less than 5% of a publicly traded class of securities or to the
performance by Cannavino of investment banking services for any entity.  If any
provision of this Section 4 is found by any court of competent jurisdiction to
be unreasonable by reason of its being too broad as to the period of time,
territory or scope, then, and in that event, such provision will nevertheless
remain valid and fully effective, but will be considered to be amended so that
the period of time, territory or scope set forth will be changed to be the
maximum period of time, the largest territory or the broadest scope, as the
case may be, that would be found reasonable and enforceable by such court.

         5.      Notice and Cure.  If, before the end of the month following
any month in which (a) Cannavino performs services for a particular company
(other than a company listed on Schedule I) that might constitute a breach of
Section 4(b), (b) knows (or would have known if he had not intentionally
avoided such knowledge) that a former employee of PSC has accepted employment
under circumstances that might constitute a breach of Section 4(c), or (c)
engages in any conduct that might be prohibited under Section 4(d)
(collectively, a "Questionable Activity"), Cannavino delivers notice to PSC
fully describing the Questionable Activity, then (i) if PSC does not deliver
written notice to Cannavino stating that such Questionable Activity constitutes
a breach of Section 4 (a "Notice of Breach") within 30 days after receiving
Cannavino's notice, then such Questionable Activity will be deemed not to
constitute a breach of Section 4, and (ii) if PSC does deliver a Notice of
Breach with respect to such Questionable Activity within such 30 day period,
then Cannavino will be deemed to have fully cured any breach of Section 4
resulting from such Questionable Activity, and PSC will have no right to
exercise remedies with respect to such breach, if within 15 days after the
Notice of Breach, (A) Cannavino ceases to engage in such Questionable Activity,
(B) in the case of clause (b) above, the services of the former employee of PSC
terminate with the entity involved, and (C) in the case of clause (c) above,
any contract with the Major Customer that was obtained in connection with such
Questionable Activity is canceled.  Except as expressly provided in this
Section 5, Cannavino will have no right to notice or cure with respect to a
breach of Section 4.

         6.      Inventions.  All inventions, improvements, technical
developments, patentable or copyrightable work products and other intellectual
property that Cannavino helps to create wholly or partly in the course of
Cannavino's work for PSC or as a result of that work or use of PSC property,
and that relates to PSC's business or any natural extension of PSC's business,
will be the property of PSC.  Cannavino will promptly disclose all of such
intellectual property to PSC.  Cannavino will have no rights to such
intellectual property and hereby assigns any such





                                   Page 3
<PAGE>   4
rights to PSC, and will execute any documents reasonably requested and provided
by PSC in order to establish, protect or enforce such rights.

         7.      Property.  At the end of Cannavino's employment, Cannavino
will promptly return all PSC property and Confidential Information to PSC, and
PSC may deduct any amounts owed by Cannavino to PSC from any amounts otherwise
due to Cannavino from PSC.

         8.      Termination.

                 (a)      PSC may terminate Cannavino's employment under this
         Agreement at any time for Cause.  "Cause" means the occurrence of any
         of the following circumstances: (i) Cannavino's refusal to follow
         proper written directions of the Board, the Chairman or the Chief
         Executive Officer as to specific actions within a reasonable specified
         period unless the action is illegal, unethical or immoral and
         Cannavino so notifies the Board and the Chief Executive Officer of
         such illegality, unethical position or immorality in writing within
         five business days of the request to Cannavino; (ii) Cannavino's
         conviction of a felony (other than a traffic violation) or (iii)
         Cannavino's commission of material fraud with regard to PSC.  "Cause"
         specifically excludes Cannavino's death or any physical or mental
         illness affecting Cannavino.

                 (b)      PSC may terminate Cannavino's employment under this
         Agreement at any time for any reason other than Cause, upon which
         termination PSC will pay Cannavino severance pay equal to two year's
         Base Salary (as defined below, using the highest Base Salary
         previously paid to Cannavino), to be paid on a semi-monthly basis;
         provided that, unless such discharge occurs within six months
         following a Change in Control, if Cannavino receives any salary,
         consulting fees or other cash compensation for services during the
         second year following discharge, then any such severance payments made
         during the second year following discharge and after Cannavino first
         earns such other cash compensation will be reduced by the amount of
         such other cash compensation.

                 (c)      Cannavino may terminate his employment under this
         Agreement for Good Reason, upon which termination PSC will pay
         Cannavino severance pay equal to two year's Base Salary (using the
         highest Base Salary previously paid to Cannavino), to be paid on a
         semi-monthly basis; provided that, unless Cannavino's Good Reason is
         as a result of an action covered by subparagraph (i)-(iv) below that
         occurs within six months following a Change in Control, if Cannavino
         receives any salary, consulting fees or other cash compensation for
         services during the second year following discharge, then any such
         severance payments made during the second year following discharge and
         after Cannavino first earns such other cash compensation will be
         reduced by the amount of such other cash compensation.  "Good Reason"
         means the occurrence of any of the reasons set forth below, if within
         60 days after such occurrence, Cannavino delivers written notice to
         the Board stating that he will terminate his employment with PSC if
         such reason is not substantially cured within 30 days, and such reason
         is not substantially cured within such 30 day period.  The reasons for
         Good Reason are the following:





                                   Page 4
<PAGE>   5
                          (i)     failure to elect Cannavino as Chief Executive
                 Officer of PSC within 12 months after the Effective Date;

                          (ii)    failure to elect Cannavino as Chairman within
                 24 months after the Effective Date (or such earlier time as
                 Morton H. Meyerson ceases to serve as Chairman), unless Morton
                 H. Meyerson is then the Chairman, in which case the failure to
                 elect Cannavino as Chairman after Morton H. Meyerson ceases to
                 be Chairman;

                          (iii)   removal of Cannavino from the position of
                 President or Chief Operating Officer (unless such removal is
                 in conjunction with his promotion to Chief Executive Officer)
                 or a material diminution in the duties associated with such
                 position;

                          (iv)    removal of Cannavino from the position of
                 Chairman or Chief Executive Officer or a material diminution
                 in the duties associated with such position;

                          (v)     a reduction in Cannavino's Base Salary;

                          (vi)    a "Change in Control" of PSC, which is
                 defined to mean any of the following events:

                                  (A)      PSC is merged, consolidated or
                          reorganized into or with another corporation or other
                          legal entity and as a result of such merger,
                          consolidation or reorganization less than 50% of the
                          combined equity interests or voting power of the then
                          outstanding securities of the remaining corporation
                          or legal entity or its ultimate parent immediately
                          after such transaction are received in respect of or
                          in exchange for voting securities of PSC pursuant to
                          such transaction;

                                  (B)      PSC sells all or substantially all
                          of its assets to any other corporation or other legal
                          entity and, immediately following such sale, the
                          equity owners of PSC prior to such sale own less than
                          50% of the combined equity interests or voting power
                          of the then outstanding securities of such other
                          corporation or legal entity or its ultimate parent;

                                  (C)      any person (including any "person"
                          as such term is used in Section 13(d)(3) or Section
                          14(d)(2) of the Securities Exchange Act of 1934, as
                          amended (the "Exchange Act")) has become the
                          beneficial owner (as the term "beneficial owner" is
                          defined under Rule 13d-3 or any successor rule or
                          regulation promulgated under the Exchange Act) of
                          securities which, when added to any securities
                          already owned by such person, would represent in the
                          aggregate (i) 50%, if PSC's common stock is not

                          directors;

                          Officer of PSC;

                                  (E)      shares of PSC common stock owned by
                          Swiss Bank Corporation ("SBC") or its affiliates are
                          voted, separately or together with shares owned by

                          PSC or any successor entity, whether by way of
                          merger, consolidation, share exchange,
                          reorganization, recapitalization or otherwise, has
                          been listed on a registered national securities
                          exchange or approved for quotation in the National
                          Association of Securities Dealers Automated Quotation
                          ("Nasdaq") system, more than 95% of the shares of PSC
                          common stock currently owned by HWGA, Ltd. and
                          Meyerson Family Limited Partnership area transferred
                          in a single or series of related transfers, other
                          than in one or more distributions to the partners of
                          such partnerships;


                 provided, however, that notwithstanding paragraphs (A), (B) or
                 (C) above, the ownership or acquisition of securities by SBC
                 or its affiliates (subject to the limitations of any agreement
                 between SBC or its affiliates and PSC) or Ross Perot

<PAGE>   7
                 or his affiliates or family members or affiliates of his
                 family members or Siemens or its affiliates (subject to the
                 limitations of any agreement between Siemens or its affiliates
                 and PSC) will not constitute, or be deemed to cause, a Change
                 in Control, except that (x) a Change in Control will be deemed
                 to have occurred if either Siemens and its affiliates or SBC
                 and its affiliates own more than 45% of the outstanding
                 securities of PSC that are entitled to elect directors and
                 such ownership continues for one year and (y) if PSC
                 terminates Cannavino's employment during such year without
                 Cause or Cannavino terminates with Good Reason, then such
                 termination will be deemed to have occurred immediately
                 following a Change in Control and Cannavino's rights under
                 this Agreement and the Option Grant will be adjusted
                 accordingly (and retroactively, to the extent necessary); or

                          (vii)   any other material breach by PSC of its
                 obligations under this Agreement.

                 (d)      Cannavino may terminate his employment under this
         Agreement without Good Reason, but in such event PSC will have no
         further obligations to Cannavino hereunder, except for the payment of
         accrued Base Salary through the date of termination.

                 (e)      The parties agree that actual damages in the event of
         a breach of this Agreement by PSC are speculative and that the
         severance payments set forth in paragraphs (b) and (c) above
         constitute liquidated damages and are a reasonable estimate of the
         actual damages that would result from a breach of this Agreement by
         PSC.  Cannavino is not entitled to any additional damages whatsoever.
         If PSC tenders such severance pay, Cannavino hereby waives and
         relinquishes any cause of action relating to his employment or
         termination under this Agreement (excluding any claim for Base Salary
         and any claim for nondiscretionary benefits, bonus payments,
         indemnification or insurance to which Cannavino is entitled under
         PSC's articles of incorporation, bylaws or other agreements binding on
         PSC, in each case through the date of termination, other than with
         respect to indemnification or director and officer insurance, and any
         claim under the Option Grant, dated as of July 27, 1995 from PSC to
         Cannavino (the "Option Grant")), and if he institutes any such cause
         of action against PSC or its directors, officers or employees under or
         in connection with this Agreement, Cannavino forfeits any entitlement
         to the severance payments provided in paragraphs (b) and (c) above and
         will be entitled to no damages whatsoever.  Notwithstanding the
         foregoing, Cannavino may bring a claim against PSC or its directors,
         officers or employees for defamation if he first returns any severance
         payments previously made hereunder, and upon bringing such claim he
         will forfeit his right to any additional severance payments hereunder
         unless and until he is successful in winning a final judgment on such
         claim (in which case PSC will be liable for the full amount of
         severance pay required hereunder).

         9.      Compensation.  During the term of this Agreement, PSC will pay
Cannavino a salary of $41,666.67 per month, which salary may be revised by the
Board from time to time (the "Base Salary"), plus a bonus, if any, to be
determined in the sole discretion of the Board and payable as of the end of
each calendar year other than 1995.  Cannavino will also receive





                                   Page 7
<PAGE>   8
a signing bonus, payable as of the Effective Date, in an amount to be
determined by the current Chairman.

         10.     Benefits.  Cannavino will be entitled to receive employee
benefits as established or revised by PSC from time to time for its senior
executive officers.  Cannavino will receive medical coverage, dependent medical
coverage and disability coverage on the same terms as the other executive
officers of PSC.  Cannavino will be entitled to indemnification and will
receive directors' and officers' liability insurance to the maximum extent
provided to other directors and executive officers of PSC and its subsidiaries
from time to time.  Cannavino will receive life insurance coverage on the same
terms as provided to the current Chairman, if Cannavino submits to a physical
examination and receives an insurability rating that provides for no higher
premium than that paid by PSC for the current Chairman; provided that, if
Cannavino's premium would be higher than that paid by PSC for the current
Chairman, Cannavino may obtain a lower amount of coverage, so as to reduce the
premium to that paid for the current Chairman, or may obtain equivalent
coverage by paying the difference between his actual rate and the rate paid for
the current Chairman.  Cannavino will be provided the benefits of the standard
PSC relocation policy provided to employees relocating when already employed by
PSC and given the most favorable reasonable alternatives within that policy in
connection with Cannavino's permanent relocation to the Dallas, Texas area,
which relocation Cannavino agrees he will make within two years of the
Effective Date.  Cannavino will be provided with a PSC paid apartment, car,
temporary living expenses and commuting expenses during the period of up to one
year prior to such permanent relocation.

         11.     Legal Fees.  PSC will pay all reasonable legal fees incurred
by Cannavino through the date hereof in connection with the negotiation and
documentation of this Agreement, the Stock Option Grant and the other documents
specifically referenced herein or therein.

         12.     Withholding.  PSC may withhold from any amounts payable under
this Agreement all federal, state, city or other taxes as may be required
pursuant to any law or government regulation or ruling.

         13.     Survival.  The provisions of Sections 3, 4, 5, 6 and 7 will
survive any termination of this Agreement and will continue to be enforceable
against Cannavino after his employment with PSC ends.

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

         15.     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 Chairman (unless Cannavino is then the Chairman, in which case
to the attention of the Board of Directors), with a copy to the General
Counsel.  Any notice to Cannavino that is required or permitted by this
Agreement must be addressed to Cannavino at the most recent address for
Cannavino reflected in the appropriate records of PSC, with copies to Proskauer
Rose Goetz & Mendelsohn LLP, 1585 Broadway, New York, New York 10036,
Attention: Michael S. Sirkin (telecopy: 212-969-2900).  Either party





                                   Page 8
<PAGE>   9
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.

         16.     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
Cannavino hereby consents to the personal jurisdiction of such courts in any
such action; provided that, at the request of PSC or Cannavino, any claim or
dispute arising out of or relating to this Agreement or Cannavino'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.  A judgment upon
the award rendered by the arbitrators may be entered by any court having
jurisdiction.  Neither party will be liable to the other for punitive damages
for any such claim or dispute.

         17.     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 discharged unless such waiver, modification or discharge is
agreed to in writing signed by Cannavino 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.

         18.     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.

         19.     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.

                                PROMISSORY NOTE


$1,400,000                                                     December 18, 1995
                                                                   Dallas, Texas


     FOR VALUE RECEIVED, James A. Cannavino ("Cannavino"), promises to pay to
Perot Systems Corporation, a Texas corporation ("PSC"), or order, at the
principal offices of PSC or at such other place as the holder of this Note may
designate, the principal sum of One Million Four Hundred Thousand Dollars
($1,400,000), together with interest on all unpaid portions of such amount from
the date of advance until repayment at the greater of (a) eight percent (8%)
per annum or (b) the "Applicable Federal Rate," which is necessary to prevent
such interest from being treated as "below market," as such terms are defined
in the Internal Revenue Code of 1986, as amended, for the month in which this
Note is executed and delivered, compounded annually.

     1.    Payment.  Reference is made to the Stock Option Grant, dated as of
July 27, 1995, by PSC in favor of Cannavino (the "Option Grant").  Capitalized
terms used in this Note that are not otherwise defined have the meanings given
to such terms in the Option Grant.  The principal and all accrued interest on
this Note will be payable in full on the earliest to occur of the following
dates (or earlier if otherwise required by this Note):
           
           (a) the fifteenth anniversary of the Effective Date;

           (b) three years after the Restricted Stock is Publicly Traded; or

           (c) six months after the first date on which the Restricted Stock is
      Publicly Traded and on which, for the preceding ten consecutive trading
      days, the product of (i) the closing price of the Restricted Stock
      multiplied by (ii) the number of shares of Vested Stock then owned by
      Cannavino is equal to or greater than two times the aggregate outstanding
      balance of principal and interest on this Note, the Covered Claims Note
      and the General Note at such time.

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

     3.    Prepayment.  Cannavino may prepay this Note in whole or in part at
any time or from time to time, without premium or penalty.  If Cannavino sells
any of the Restricted Stock, then Cannavino will promptly (and in any event
within five days after the completion of each such sale) make a prepayment in
an amount equal to the proceeds of such sale, less any federal income taxes
incurred by Cannavino as a result of such sale, which will be applied to this
Note, the Covered Claims Note and the General Note as follows (but, in each
case, not to exceed the unpaid balance of principal and interest then
outstanding under such Notes, if any): (a) to this Note, in an amount equal to
$1.40 for each share of Restricted Stock sold, plus the accrued interest on the
Purchase Price Note applicable to such $1.40 per share; (b) to the Covered
Claims      


                                     Page 1
<PAGE>   2

Note; (c) to the General Note; and (d) to any remaining balance on this Note;
provided that, if Restricted Stock is sold upon exercise of the Put Option
under the circumstances described in the last sentence of Section 9 of the
Option Grant, Cannavino may apply the proceeds of such sale to his excise tax
liability before making the payments required by clauses (b), (c) and (d)
above.  Any prepayment under this paragraph will be applied first to accrued
but unpaid interest and then to principal.

     4.    Offset Rights.  Pursuant to the Option Grant, (a) PSC has the right
to satisfy certain payment obligations to Cannavino under the Option Grant by
offset against amounts, whether or not then otherwise due, under this Note, and
any amount so offset will automatically be deemed due and payable hereunder
without notice or demand, and (b) Cannavino has the right to satisfy his
obligations to PSC under this Note by offset against amounts owing from PSC to
Cannavino under the Option Grant.  This Note may not be assigned by PSC.
            
     5.    Events of Default.  This Note will become immediately due and
payable without notice or demand upon the occurrence at any time of any of the
following events of default (individually, an "Event of Default" and
collectively, "Events of Default"):
            
           (a) the failure by Cannavino to make any required payment of
      principal or interest on this Note within five days after PSC gives
      written notice of such failure to Cannavino;

           (b) the institution against Cannavino of any proceedings under the
      United States Bankruptcy Code or any other federal or state bankruptcy,
      reorganization, receivership, insolvency or other similar law affecting
      the rights of creditors generally, which proceeding is not dismissed
      within 60 days of filing; or

           (c) the institution by Cannavino of any proceedings under the United
      States Bankruptcy Code or any other federal or state bankruptcy,
      reorganization, receivership, insolvency or other similar law affecting
      the rights of creditors generally or the making by Cannavino or any
      endorser or guarantor of this Note of a composition or an assignment or
      trust mortgage for the benefit of creditors.

      6.   Default Interest.  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 otherwise applicable under this Note 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 Cannavino
with respect to the payment of such interest has been discharged (whether
before or after judgment).

     7.    Maximum Rate.  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 Cannavino, then such excess sum shall be
credited by the holder as a payment of principal.

     8.    Collection Costs.  The Cannavino agrees to pay on demand all costs of
collection, including reasonable attorneys' fees, incurred by the holder in
enforcing the obligations of Cannavino under this Note.

     9.    Waivers.  No delay or omission on the part of the holder in
exercising any right under this Note or the Pledge Agreement 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.  Cannavino 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.
           
     10.   Amendments.  None of the terms or provisions of this Note may be
excluded, 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 excluded, modified or amended.

     11.   Enforcement.  This Note 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.  Any action to enforce the provisions of, or otherwise
relating to, this Note may be brought in the appropriate courts in Dallas,
Dallas County, Texas, and Cannavino hereby consents to the personal
jurisdiction of such courts in any such action; provided that, at the request
of PSC or Cannavino, any claim or dispute arising out of or relating to this
Note or the indebtedness evidenced hereby 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.  A judgment upon the award rendered by the arbitrators may be
entered by any court having jurisdiction.  Neither party will be liable to the
other for punitive damages for any such claim or dispute.

                                PROMISSORY NOTE

$1,500,000                                                       January 1, 1996
                                                                   Dallas, Texas

     FOR VALUE RECEIVED, James A. Cannavino ("Cannavino"), promises to pay to
Perot Systems Corporation, a Delaware corporation ("PSC"), or order, at the
principal offices of PSC or at such other place as the holder of this Note may
designate, the principal sum of One Million Five Hundred Thousand Dollars
($1,500,000), or such lesser amount as may be advanced by PSC to Cannavino
hereunder, together with interest on all unpaid portions of such amount from
the date of advance until repayment at the "Applicable Federal Rate," which is
necessary to prevent such interest from being treated as "below market," as
such terms are defined in the Internal Revenue Code of 1986, as amended, for
the month in which this Note is executed and delivered, compounded annually.

     1.    Payment.  Reference is made to the Stock Option Grant, dated as of
July 27, 1995, by PSC in favor of Cannavino (the "Option Grant").  Capitalized
terms used in this Note that are not otherwise defined have the meanings given
to such terms in the Option Grant.  The principal and all accrued interest on
this Note will be payable in full on the earliest to occur of the following
dates (or earlier if otherwise required by this Note):
           
           (a) the fifteenth anniversary of the Effective Date;

           (b) three years after the Restricted Stock is Publicly Traded; or

           (c) six months after the first date on which the Restricted Stock is
      Publicly Traded and on which, for the preceding ten consecutive trading
      days, the product of (i) the closing price of the Restricted Stock
      multiplied by (ii) the number of shares of Vested Stock then owned by
      Cannavino is equal to or greater than two times the aggregate outstanding
      balance of principal and interest on this Note, the Purchase Price Note
      and the Covered Claims Note at such time.

     2.    Security.  Payment of this Note is secured pursuant to a Pledge
Agreement dated as of December 18, 1995, between PSC and Cannavino (the "Pledge
Agreement").

     3.    Prepayment.  Cannavino may prepay this Note in whole or in part at
any time or from time to time, without premium or penalty.  If Cannavino sells
any of the Restricted Stock, then Cannavino will promptly (and in any event
within five days after the completion of each such sale) make a prepayment in
an amount equal to the proceeds of such sale, less any federal income taxes
incurred by Cannavino as a result of such sale, which will be applied to this
Note, the Purchase Price Note and the Covered Claims Note as follows (but, in
each case, not to exceed the unpaid balance of principal and interest then
outstanding under such Notes, if any): (a) to the Purchase Price Note, in an
amount equal to $.70 for each share of Restricted Stock (such Restricted Stock
being the shares existing after PSC's two for one stock split effective
December 1995) sold, plus the accrued interest on the Purchase Price Note
applicable to such $.70 per
           



                                     Page 1
<PAGE>   2

share; (b) to the Covered Claims Note; (c) to this Note; and (d) to any
remaining balance on the Purchase Price Note; provided that, if Restricted
Stock is sold upon exercise of the Put Option under the circumstances described
in the last sentence of Section 9 of the Option Grant, Cannavino may apply the
proceeds of such sale to his excise tax liability before making the payments
required by clauses (b), (c) and (d) above.  Any prepayment under this
paragraph will be applied first to accrued but unpaid interest and then to
principal.

     4.    Recourse.  Recourse of the holder of this Note is limited to the
Collateral (as defined in the Pledge Agreement), and Cannavino has no personal
or other liability for such amounts except as to such Collateral on the terms
set forth in the Pledge Agreement; provided that (a) if, prior to the maturity
date of this Note, (i) Cannavino's employment with PSC is terminated for Cause
(as defined in the Employment Agreement) or (ii) Cannavino terminates his
employment with PSC without Good Reason (as defined in the Employment
Agreement), then, beginning on the date of such transfer or termination, the
holder of this Note will have full recourse against Cannavino and Cannavino
will be personally liable for all of the obligations evidenced hereby, and (b)
if Cannavino sells or otherwise transfers all or any portion of the Restricted
Stock (other than a transfer pursuant to Section 4(e) of the Option Grant, but
including any sale or other transfer by a transferee under such Section 4(e)),
then the holder of this Note will have full recourse against Cannavino with
respect to, and Cannavino will be personally liable for, any advances made
under this Note after the date of such sale or transfer, plus accrued interest
on any such advances.

     5.    Offset Rights.  Pursuant to the Option Grant, (a) PSC has the right
to satisfy certain payment obligations to Cannavino under the Option Grant by
offset against amounts, whether or not then otherwise due, under this Note, and
any amount so offset will automatically be deemed due and payable hereunder
without notice or demand, and (b) Cannavino has the right to satisfy his
obligations to PSC under this Note by offset against amounts owing from PSC to
Cannavino under the Option Grant.  This Note may not be assigned by PSC.
           
     6.    Events of Default.  This Note shall become immediately due and
payable without notice or demand upon the occurrence at any time of any of the
following events of default (individually, an "Event of Default" and
collectively, "Events of Default"):
           
           (a) the failure by Cannavino to make any required payment of
      principal or interest on this Note within five days after PSC gives
      notice of such failure to Cannavino;

           (b) the institution against Cannavino of any proceedings under the
      United States Bankruptcy Code or any other federal or state bankruptcy,
      reorganization, receivership, insolvency or other similar law affecting
      the rights of creditors generally, which proceeding is not dismissed
      within 60 days of filing; or

           (c) the institution by Cannavino of any proceedings under the United
      States Bankruptcy Code or any other federal or state bankruptcy,
      reorganization, receivership, insolvency or other similar law affecting
      the rights of creditors generally or the making

                                     Page 2

<PAGE>   3

      by Cannavino or any endorser or guarantor of this Note of a composition
      or an assignment or trust mortgage for the benefit of creditors.

     7.    Default Interest.  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 otherwise applicable under this Note 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 Cannavino
with respect to the payment of such interest has been discharged (whether
before or after judgment).

     8.    Maximum Rate.  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 Cannavino, then such excess sum shall be
credited by the holder as a payment of principal.

     9.    Waivers.  No delay or omission on the part of the holder in
exercising any right under this Note or the Pledge Agreement 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.  Cannavino 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.
           
     10.   Amendments.  None of the terms or provisions of this Note may be
excluded, 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 excluded, modified or amended.

     11.   Enforcement.  This Note 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.  Any action to enforce the provisions of, or otherwise
relating to, this Note may be brought in the appropriate courts in Dallas,
Dallas County, Texas, and Cannavino hereby consents to the personal
jurisdiction of such courts in any such action; provided that, at the request
of PSC or Cannavino, any claim or dispute arising out of or relating to this
Note or the indebtedness evidenced hereby 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.  A judgment upon the award rendered by the arbitrators may be
entered by any court having jurisdiction.  Neither party will be liable to the
other for punitive damages for any such claim or dispute.

                                PLEDGE AGREEMENT


     This Pledge Agreement (the "Agreement") is made as of December 18, 1995,
by and between Perot Systems Corporation, a Texas corporation ("PSC"), and
James A. Cannavino ("Cannavino").

     WHEREAS, PSC has granted Cannavino the option to purchase 1,000,000 shares
of PSC's common stock pursuant to a Stock Option Grant dated as of July 27,
1995 (the "Option Grant");

     WHEREAS, in accordance with the Option Grant, PSC has extended credit to
Cannavino and may extend additional credit pursuant to the terms of a Purchase
Price Note, a Covered Claims Note and a General Note (as such terms are defined
in the Option Grant, the "Notes");

     NOW, THEREFORE, to secure the Obligations (as defined below), Cannavino
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 Option Grant.
           
     2.    Pledge of Securities.  Cannavino hereby pledges and grants to PSC a
security interest in the following:

           (a) the Option and any Restricted Stock purchased by Cannavino
      pursuant to the Option, 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");  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

                                     Page 1

<PAGE>   2



or modify, any obligation of Cannavino 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 Cannavino to PSC, whether now outstanding or incurred after the
date hereof (the "Obligations"):  (a) all principal, interest, fees, expenses,
obligations and liabilities of Cannavino 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)
Cannavino's performance of his obligations under the Notes, this Agreement and
the Option Grant; and (d) all renewals, extensions and modifications of the
indebtedness and obligations referred to in the foregoing clauses, or any part
thereof.

     4.    Cannavino's Warranties and Indemnity.  Cannavino represents, warrants
and covenants to PSC (a) that he is and (except as provided in Section 6) will
be the lawful owner of the Securities, (b) that the Securities are and (except
as provided in Section 6) will remain free and clear of all liens, encumbrances
and security interests other than the security interest granted by Cannavino
hereunder, and (c) that Cannavino has the right and authority to pledge the
Securities and otherwise to comply with the provisions hereof.  In the event
that 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,
Cannavino 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 Cannavino upon demand,
and shall become part of the Obligations of Cannavino secured pursuant to this
Agreement.  PSC hereby consents to the pledge of the Securities to PSC
hereunder, notwithstanding any restrictions on transfer of the Securities set
forth in the Option Grant.

     5.    Negative Covenants.  Cannavino covenants and agrees that, unless PSC
otherwise consents in writing and except as provided in Section 6, Cannavino
will not: (a) sell, assign or transfer any rights of Cannavino 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.    Sale of Collateral.  So long as no Event of Default (as defined in
the Note) or event that with notice or passage of time or both would constitute
an Event of Default (a "Potential Default") has occurred and is continuing,
Cannavino may (subject to the provisions of the Option Grant):
           
           (a) transfer Restricted Stock to a maximum of two transferees
      pursuant to Section 4(e) of the Option Grant; provided that any such
      transfer must be effected pursuant to documentation reasonably acceptable
      in form and substance to PSC, and such documentation must provide that
      the Restricted Stock transferred remains subject to all of

                                     Page 2

<PAGE>   3



      the vesting provisions, transfer restrictions, repurchase options and
      other provisions of the Option Grant and this Agreement, in each case as
      if such Restricted Stock continued to be held by Cannavino; or

           (b) sell all or any portion of his Vested Stock to PSC pursuant to
      the Put Option or for cash to an unaffiliated buyer; provided that (i) in
      a sale to an unaffiliated buyer, if the Vested Stock is Publicly Traded
      at such time, the Vested Stock must be sold at the market price in a
      "brokers' transaction" as defined in Rule 144(g) under the Securities
      Act, and (ii) upon any sale of Vested Stock, Cannavino must promptly (and
      in any event within five days after the completion of each such sale) pay
      to PSC in respect of the Obligations an amount equal to the proceeds of
      such sale less any federal income taxes incurred by Cannavino as a result
      of such sale.  Pending such payment, such net proceeds will continue to
      constitute Collateral hereunder.

PSC will deliver certificates representing the Vested Stock to Cannavino and
take such other action as may be necessary to allow a sale of Vested Stock in
accordance with this Section 6.

      7.   Dividends and Other Distributions.

           (a) Cannavino 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, 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 Cannavino, 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, Cannavino shall be entitled to receive any cash
      dividends payable in respect of the Securities; provided that, upon
      receipt of any such cash dividend, Cannavino 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 Cannavino as a result of such
      cash dividend, and, pending such payment, such cash dividend will
      continue to constitute Collateral hereunder.

      8.   Voting Rights.  So long as no Event of Default or Potential Default
has occurred and is continuing, Cannavino shall be entitled to exercise any and
all voting rights pertaining to the Securities for any purpose not inconsistent
with the terms of the Note or this Agreement.
           
      9.   Termination of Rights.  During any period when an Event of Default
has occurred and is continuing, all rights of Cannavino to sell Vested Stock
pursuant to Section 6, to receive dividends pursuant to Section 7(b) or to
exercise voting rights pursuant to Section 8 shall cease and all such rights
shall thereupon become vested in PSC, which shall have the sole and
           
                                     Page 3

<PAGE>   4



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 9 shall be retained by PSC as additional collateral hereunder and may
be applied in accordance with the provisions hereof.

      10.  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 Option Grant, 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 except as required under the Notes (including notice of
      intention to accelerate and notice of acceleration), 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
      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 Cannavino
      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 11 hereof.

           (b) Sale of Securities.  Cannavino 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.  Cannavino 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

                                     Page 4

<PAGE>   5



      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 Cannavino
      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 Cannavino 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 he 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 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, Cannavino 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 Cannavino's best efforts to secure the same.

           (c) Limitations on Right to Sell Securities.  Notwithstanding any
      other provisions of this Agreement (i) Restricted Stock may not be sold
      by PSC unless it has vested in accordance with the Option Grant and (ii)
      the Option may not be sold or otherwise transferred by PSC, in whole or
      in part, at any time, and PSC's remedies with respect to the Option will
      be limited to retaining or canceling the Option.

           (d) 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 Cannavino and to any other
      person entitled under the Code to notice; provided, that if the
      Collateral

                                     Page 5

<PAGE>   6



      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.

           (e) 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 Cannavino as prescribed by the Code or as a court
      of competent jurisdiction may direct.

      11.  Attorney-in-Fact.  Cannavino hereby appoints PSC as the
attorney-in-fact for Cannavino 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 Cannavino 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.

      12.  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 Cannavino 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 Cannavino, any actions and conditions, obligations or covenants which
      Cannavino has failed or refused to

                                     Page 6

<PAGE>   7



      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.

      13.  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 Cannavino 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 Cannavino 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.

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

      15.  Repurchase Option. In the event that PSC exercises its right to
cancel or repurchase any of the Securities under the Option Grant, 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 Option
Grant.     

     16.   Further Assurances.  Cannavino 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. 

     17.   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 Cannavino is then serving in such capacity, in which case such action
will be taken by the Board.
           
     18.   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 Chairman of the Board (unless Cannavino is then the Chairman of the Board,
in which case to the attention of the Board of Directors), with a copy to the
General Counsel.  Any notice to Cannavino that is required or permitted by this
Agreement must be addressed to Cannavino at the most recent address for
Cannavino reflected in the appropriate records of PSC, with copies to Proskauer
Rose Goetz &

invalid or unenforceable for any reason, the validity and enforceability of all
other provisions of this Agreement will not be affected thereby.

<PAGE>   3


       c.   Any reference to "a General Note" in the Pledge Agreement
            shall hereinafter mean the General Note as amended by this
            Modification Agreement; and

            amended by this Modification Agreement shall secure payment and
            performance of all Cannavino's obligations under the Purchase Price
            Note and the General Note;

4.    Cannavino and PSC hereby acknowledge that the unpaid principal balance of
      the General Note as of the date hereof is Six Hundred Fourteen Thousand
      Five Hundred Eighty-Seven and 70/100 Dollars ($614,587.70) plus interest
      thereon.

5.    General Note.  The General Note is hereby amended as follows:

      a.   The principal Sum of the General Note is increased and
           amended to read $2,415,000;

      b.   The lead in paragraph and paragraphs 1 - 4 are deleted in
           their entirety and substituted in lieu thereof are the following:

           FOR VALUE RECEIVED, James A. Cannavino ("Cannavino"), promises to pay
           to Perot Systems Corporation, a Delaware corporation ("PSC"), or
           order, at the principle offices of PSC or at such other place as the
           holder of this Note may designate, the principal sum of Two Million
           One Hundred Fifteen Thousand Dollars ($2,415,000), or such lesser
           amount as may be advanced by PSC to Cannavino hereunder, together
           with interest (a) on all unpaid portions of the Initial Advance (as
           defined below) from the date of advance until repayment at the
           "Applicable Federal Rate," which is necessary to prevent such
           interest from being treated as "below market," as such terms are
           defined in the Internal Revenue Code of 1986, as amended, for the
           month in which this Note is executed and delivered, compounded
           annually, and (b) on all unpaid portions other than the Initial
           Advance from the date of the advance until repayment at the greater
           of (i) seven and one-quarter percent (7.25%) per annum or (ii) the
           "Applicable Federal Rate," which is necessary to prevent such
           interest from being treated as "below market," as such terms are
           defined in the Internal Revenue Code of 1986, as amended, for the
           month in which the advance is made, compounded annually.

           1.    Payment.  Reference is made to the Stock Option Grant, dated as
           of July 27, 1995, by PSC in favor of Cannavino as modified and
           amended by that certain Modification Agreement dated as of March, 7
           1997 executed by and between Cannavino and PSC (the "Modification
           Agreement") (the Stock Option Grant as modified by the Modification
           Agreement is hereafter called the "Option Grant"). Capitalized terms
           used in this Note that are not otherwise defined have the meanings
           given to such terms in the Option Grant.  Principal plus interest on
           this Note shall be payable as follows:
           
                 (a) The principal and all accrued interest on the initial
                 advance made

                  under this Note in the amount of $614,587.70 (the "Initial
                  Advance") will be payable in full on the earliest to occur of
                  the following dates (or earlier if otherwise required by this
                  Note):

                        (i)   the fifteenth anniversary of the Effective Date;

                        (ii)  three years after the Restricted Stock is Publicly
                        Traded; or

                        (iii) six months after the first date on which the
                        Restricted Stock is Publicly Traded and on which, for
                        the preceding ten consecutive trading days, the product
                        of (i) the closing price of the Restricted Stock
                        multiplied by (ii) the number of shares of Vested Stock
                        then owned by Cannavino is equal to or greater than two
                        times the aggregate outstanding balance of principal
                        and interest on this Note and the Purchase Price Note
                        at such time.

                  made after the Initial Advance will be payable in full on the

                  otherwise required by this Note):

                        (i)   the fifteenth anniversary of the Effective Date;

                        (ii)  five years after the Restricted Stock is Publicly
                        Traded; or

                        (iii) six months after the first date on which the
                        Restricted Stock is Publicly Traded and on which, for
                        the preceding ten consecutive trading days, the product
                        of (i) the closing price of the Restricted Stock
                        multiplied by (ii) the number of shares of Vested Stock
                        then owned by Cannavino is equal to or greater than two
                        times the aggregate outstanding balance of principal
                        and interest on this Note and the Purchase Price Note
                        at such time.

            2.    Security.  Payment of this Note is secured pursuant to a
            Pledge Agreement dated as of December 18, 1995, between PSC and
            Cannavino as modified by the Modification Agreement (the "Pledge
            Agreement").
                  
            3.    Prepayment.  Cannavino may prepay this Note in whole or in
            part at any time or from time to time, without premium or penalty. 
            If Cannavino sells any of the Restricted Stock, then Cannavino will
            promptly (and in any event within five days after the completion of
            each such sale) make a prepayment in an amount equal to the
            proceeds of such sale, less any federal income taxes incurred by
            Cannavino as a result of such sale, which will be applied to this
            Note and the Purchase Price Note as follows (but, in each case, not
            to exceed the unpaid balance of principal and interest then
            outstanding under such Notes, if any): (a) to the Purchase Price
            Note, in an amount equal to $.70 for each share of Restricted Stock
            (such Restricted Stock being the shares existing after PSC's two
            for one stock split effective December 1995) sold, plus the accrued
            interest on the Purchase Price Note applicable to such $.70 per
            share; (b) to this Note; and (c) to any remaining balance on the
            Purchase Price Note; provided that, if Restricted Stock is sold
            upon exercise of the Put Option under the circumstances described
                  
                                     Page 4

<PAGE>   5

            in the last sentence of Section 9 of the Option Grant, Cannavino
            may apply the proceeds of such sale to his excise tax liability
            before making the payments required by clauses (b) and (c).  Any
            prepayment under this paragraph resulting from the sale of
            Restricted Stock will be applied first to accrued but unpaid
            interest and then to principal in the order of borrowings with the
            earliest borrowed principal paid first.  Any prepayment other than
            resulting from the sale of Restricted Stock  will be applied first
            to accrued but unpaid interest and then to principal in the order
            of borrowings with the latest borrowed principal paid first.  With
            each prepayment, Cannavino will give PSC a written statement
            indicating whether the prepayment is a result of the sale of
            Restricted Stock.

            4.    Recourse. Recourse of the holder of this Note is limited to
            (a) full recourse and liability for all amounts advanced hereunder
            except the Initial Advance and interest thereon and (b) the
            Collateral (as defined in the Pledge Agreement), and Cannavino has
            no personal or other liability for the Initial Advance and interest
            thereon except as to such Collateral on the terms set forth in the
            Pledge Agreement; provided that if, prior to the maturity date of
            this Note, (i) Cannavino's employment with PSC is terminated for
            Cause (as defined in the Employment Agreement) or (ii) Cannavino
            terminates his employment with PSC without Good Reason (as defined
            in the Employment Agreement), then, beginning on the date of such
            transfer or termination, the holder of this Note will have full
            recourse against Cannavino and Cannavino will be personally liable
            for all of the obligations evidenced hereby.
                  
5.   Except as provided herein, the terms and provisions of the General Note,
     the Purchase Price Note, the Pledge Agreement and the Option Grant shall
     remain unchanged and shall remain in full force and effect.  Any
     modification herein of the General Note, the Purchase Price Note, the
     Pledge Agreement and the Option Grant shall in no way affect the security
     of the Pledge Agreement for the payment of the General Note, the Purchase
     Price Note.  The General Note and the Purchase Price Note, the Pledge
     Agreement and the Option Grant as modified and amended hereby are hereby
     ratified and confirmed in all respects.  All security interests granted or
     created by or existing under the Pledge Agreement remain unchanged and
     continue, unabated, in full force and effect, to secure Cannavino's
     obligation to repay the General Note and the Purchase Price Note.

6.   In addition to the modifications set forth above, PSC agrees to loan
     Cannavino up to an additional $1,000,000 in connection with his purchase
     of a home in the greater Dallas area under a general recourse note,
     payable no later than 5 years from the date of the note, with
     substantially the terms set forth for the new loans otherwise provided for
     by this Modification Agreement, and additionally secured by a mortgage on
     such property, pursuant to documentation satisfactory to both PSC and
     Cannavino.  As a condition to such a loan, the property in question must
     have an appraised value of at least the amount of principal borrowed under
     the loan and the borrowing must take place prior to December 31, 1997.

7.   This Agreement supersedes and merges all prior and contemporaneous
     promises, representations and agreements.  No provision of this Agreement,
     the General Note, the Purchase Price Note, the Pledge Agreement or the
     Option Grant may be modified, waived or discharged unless such waiver,
     modification or discharge is agreed to in writing signed by Cannavino and
     PSC.  No waiver by either party hereto of any condition or provision

                                     Page 5

<PAGE>   6


     of this Agreement, the General Note, the Purchase Price Note, the Pledge
     Agreement or the Option Grant 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.

8.   This Agreement may be executed in any number of counterparts with the same
     effect as if all parties hereto had signed the same document.  All such
     counterparts shall be construed together and shall constitute one
     instrument, but in making proof hereof it shall only be necessary to
     produce one such counterpart.

9.   If any covenant, condition, or provision herein contained is held to be
     invalid by final judgment of any court of competent jurisdiction, the
     invalidity of such covenant, condition, or shall not in any way affect any
     other covenant, condition or provision herein contained.

10.  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
     Cannavino hereby consents to the personal jurisdiction of such courts in
     any such action; provided that, at the request of PSC or Cannavino, any
     claim or dispute arising out of or relating to this Agreement 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
     Cannavino becomes liable for any such fees, costs or other disbursements,
     such amounts will become Obligations under the applicable Note secured by
     this Agreement.

11.  The terms and provisions hereof shall be binding upon and inure to the
     benefit of the parties hereto, their heirs, representatives, successors
     and assigns.

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

        For value received and to secure payment of the note, Grantor conveys
the property to Trustee in trust. Grantor warrants and agrees to defend the
title to the property. If Grantor performs all the covenants and pays the note
according to its terms, this deed of trust shall have no further effect, and
Beneficiary shall release it at Grantor's expense.

GRANTOR'S OBLIGATIONS
        Grantor agrees to:
                1.  keep the property in good repair and condition;
                2.  pay all taxes and assessments on the property when due;
                3.  preserve the lien's priority as it is established in this
                    deed of trust;
                4.  maintain, in a form acceptable to Beneficiary, an insurance
                    policy that:
                    a. covers all improvements for their full insurable value
                       as determined when the policy is issued and renewed, 
                       unless Beneficiary approves a smaller amount in writing;
                    b. contains an 80% coinsurance clause;
                    c. provides fire and extended coverage, including
                       windstorm coverage; 
                    d. protects Beneficiary with a standard mortgage clause;
                    e. provides flood insurance at any time the property is in
                       a flood hazard area; and
                    f. contains such other coverage as Beneficiary may
                    reasonably require; 
                5.  comply at all times with the requirements of the 80%
                    coinsurance clause;
                6.  deliver the insurance policy to Beneficiary and deliver
                    renewals to Beneficiary at least ten days before expiration;
                7.  keep any buildings occupied as required by the insurance
                    policy; and
                8.  if this is not a first lien, pay all prior lien notes that
                    Grantor is personally liable to pay and abide by all prior 
                    lien instruments.


BENEFICIARY'S RIGHTS
                1.  Beneficiary may appoint in writing a substitute or
                    successor trustee, succeeding to all rights and
                    responsibilities of Trustee.
                2.  If the proceeds of the note are used to pay any debt
                    secured by prior liens, Beneficiary is subrogated to all of
                    the rights and liens of the holders of any debt so paid.
                3.  Beneficiary may apply any proceeds received under the
                    insurance policy either to reduce the note or to repair or
                    replace damaged or destroyed improvements covered by the
                    policy.
                4.  If Grantor fails to perform any of Grantor's obligations,
                    Beneficiary may perform those obligations and be reimbursed
                    by Grantor on demand at the place where the note is payable
                    for any sums so paid, including attorney's fees, plus
                    interest on those sums from the dates of payment at the
                    rate stated in the note for matured, unpaid amounts. The
                    sum to be reimbursed shall be secured by this deed of 
                    trust.
                5.  If Grantor defaults on the note or fails to perform any of
                    Grantor's obligations or if default occurs on a prior lien
                    note or other instrument, and the default continues after
                    Beneficiary gives Grantor notice of the default and the time
                    within which it must be cured, as may be required by law or
                    by written agreement, then Beneficiary may:
                    a.  declare the unpaid principal balance and earned
                        interest on the note immediately due;
                    b.  request Trustee to foreclose this lien, in which case
                        Beneficiary or Beneficiary's agent shall give notice of
                        the foreclosure sale as provided by the Texas Property
                        Code as then amended; and
                    c.  purchase the property at any foreclosure sale by
                        offering the highest bid and then have the bid credited
                        on the note.


TRUSTEE'S DUTIES
        If requested by Beneficiary to foreclose this lien, Trustee shall:
                1.  either personally or by agent give notice of the
                    foreclosure sale as required by the Texas Property Code as
                    then amended;
                2.  sell and convey all or part of the property to the highest
                    bidder for cash with a general warranty binding Grantor,
                    subject to prior liens and to other exceptions to
                    conveyance and warranty; and
                3.  from the proceeds of the sale, pay, in this order:
                    a.  expenses of foreclosure, including a commission to
                        Trustee of 5% of the bid;
                    b.  to Beneficiary, the full amount of principal, interest,
                        attorney's fees, and other charges due and unpaid;
                    c.  any amounts required by law to be paid before payment to
                        Grantor; and           
                    d.  to Grantor, any balance.
<PAGE>   3
GENERAL PROVISIONS
        1.  If any of the property is sold under this deed of trust, Grantor
shall immediately surrender possession to the purchaser.  If Grantor fails to do
so, Grantor shall become a tenant at sufferance of the purchaser, subject to an
action for forcible detainer.
        2.  Recitals in any Trustee's deed conveying the property will be
presumed to be true.
        3.  Proceeding under this deed of trust, filing suit for foreclosure,
or pursuing any other remedy will not constitute an election of remedies.
        4.  This lien shall remain superior to liens later created even if the
time of payment of all or part of the note is extended or part of the property
is released.
        5.  If any portion of the note cannot be lawfully secured by this deed
of trust, payments shall be applied first to discharge that portion.
        6.  Grantor assigns to Beneficiary all sums payable to or received by
Grantor from condemnation of all or part of the property, from private sale in
lieu of condemnation and from damages caused by public works or construction on
or near the property.  After deducting any expenses incurred, including
attorney's fees, Beneficiary may release any remaining sums to Grantor or
apply such sums to reduce the note.  Beneficiary shall not be liable for
failure to collect or to exercise diligence in collecting any such sums.
        7.  Grantor assigns to Beneficiary absolutely, not only as collateral,
all present and future rent and other income and receipts from the property.
Leases are not assigned.  Grantor warrants the validity and enforceability of
the assignment. Grantor may as Beneficiary's licensee collect rent and other
income and receipts as long as Grantor is not in default under the note or this
deed of trust.  Grantor will apply all rent and other income and receipts to
payment of the note and performance of this deed of trust, but if the rent and
other income and receipts exceed the amount due under the note and deed of
trust, Grantor may retain the excess.  If Grantor defaults in payment of the
note or performance of this deed of trust.  Beneficiary may terminate Grantor's
license to collect and then as Grantor's agent may rent the property if it is
vacant and collect all rent and other income and receipts.  Beneficiary neither
has nor assumes any obligations as lessor or landlord with respect to any
occupant of the property.  Beneficiary may exercise Beneficiary's rights and
remedies under this paragraph without taking possession of the property. 
Beneficiary shall apply all rent and other income and receipts collected under
this paragraph first to expenses incurred in exercising Beneficiary's rights
and remedies and then to Grantor's obligations under the note and this deed of
trust in the order determined by Beneficiary.  Beneficiary is not required to
act under this paragraph, and acting under this paragraph does not waive any of
Beneficiary's other rights or remedies.  If Grantor becomes a voluntary or
involuntary bankrupt, Beneficiary's filing a proof of claim in bankruptcy will
be tantamount to the appointment of a receiver under Texas law.
        8.  Interest on the debt secured by this deed of trust shall not
exceed the maximum amount of nonusurious interest that may be contracted for,
taken, reserved, charged, or received under law; any interest in excess of that
maximum amount shall be credited on the principal of the debt or, if that has
been paid, refunded.  On any acceleration or required or permitted prepayment,
any such excess shall be canceled automatically as of the acceleration or
prepayment or, if already paid, credited on the principal of the debt or, if
the principal of the debt has been paid, refunded.  This provision overrides
other provisions in this and all other instruments concerning the debt.
        9.  When the context requires, singular nouns and pronouns include the
plural.
       10.  The term note includes all sums secured by this deed of trust.
       11.  This deed of trust shall bind, inure to the benefit of, and be
exercised by successors in interest of all parties.
       12.  If Grantor and Maker are not the same person, the term Grantor shall
include Maker.
       13.  Grantor represents that this deed of trust and the note are given
for the following purposes:

         FOR VALUE RECEIVED, James A. Cannavino ("Cannavino"), promises to pay
to Perot Systems Corporation, a Texas corporation ("PSC"), or order, at the
principal offices of PSC or at such other place as the holder of this Note may
designate, the principal sum of One Million and No/100ths Dollars
($1,000,000.00), together with interest on all unpaid portions of such amount
from the date of advance until repayment at the greater of (a) seven and
one-quarter percent (7 1/4%) per annum or (b) the "Applicable Federal Rate,"
which is necessary to prevent such interest from being treated as "below
market," as such terms are defined in the Internal Revenue Code of 1986, as
amended, for the month in which this Note is executed and delivered.

         1.      Payment. The principal on this Note will be payable in full on
the fifth (5th) anniversary of the date hereof. Accrued and unpaid interest
shall be due and payable annually on or before December 31 of each year during
the term hereof, commencing December 31, 1997, and at maturity.

         2.      Security. Payment of this Note is secured pursuant to a Deed
of Trust of even date herewith between Peter Altabef, Trustee, and Cannavino
(the "Deed of Trust"), covering a residence located at Dallas, Texas (the
"Property").

         3.      Prepayment. Cannavino may prepay this Note in whole or in part
at any time or from time to time, without premium or penalty. If Cannavino
sells the Property, then Cannavino will promptly prepay this Note in full. Any
prepayment under this paragraph will be applied first to accrued but unpaid
interest and then to principal.

         4.      Events of Default. This Note will become immediately due and
payable without additional notice or demand upon the occurrence at any time of
any of the following events of default (individually, an "Event of Default" and
collectively, "Events of Default"):

                 (a)      the failure by Cannavino to make any required payment
         of principal or interest on this Note within five (5) days after PSC
         gives notice of such failure to Cannavino;

                 (b)      the failure by Cannavino to satisfy his other
         obligations under the Deed of Trust within thirty (30) days after PSC
         gives written notice of such failure to Cannavino;

                 (c)      the institution against Cannavino of any proceedings
         under the United States Bankruptcy Code or any other federal or state
         bankruptcy, reorganization,




Page 1 of 3
<PAGE>   2
         receivership, insolvency or other similar law affecting the rights of
         creditors generally, which proceeding is not dismissed within sixty
         (60) days of filing; or

                 (d)      the institution by Cannavino of any proceedings under
         the United States Bankruptcy Code or any other federal or state
         bankruptcy, reorganization, receivership, insolvency or other similar
         law affecting the rights of creditors generally or the making by
         Cannavino of a composition or an assignment or trust mortgage for the
         benefit of creditors.

         5.      Default Interest. 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 lessor of (a) two
percentage points above the rate otherwise applicable under this Note 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
Cannavino with respect to the payment of such interest has been discharged
(whether before or after judgment).

         6.      Maximum Rate. 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 Cannavino, then such excess
sum shall be credited by the holder as a payment of principal.

         7.      Collection Costs. Cannavino agrees to pay on demand all costs
of collection, including reasonable attorneys' fees, incurred by holder in
enforcing the obligations of Cannavino under this Note.

         8.      Waivers. No delay or omission on the part of the holder in
exercising any right under this Note or the Pledge Agreement 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. Cannavino 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.

         9.      Amendments. None of the terms or provisions of this Note may
be excluded, 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 excluded, modified or amended.

         10.     Enforcement. This Note 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. Any action to enforce the provisions of, or otherwise
relating to, this Note may be brought in the appropriate courts in Dallas,
Dallas County, Texas, and Cannavino hereby consents to the personal
jurisdiction of such courts in any such action; provided that, at the request
of PSC or Cannavino,




Page 2 of 3

any claim or dispute arising out of or relating to this Note or the
indebtedness evidenced hereby will be resolved without resort to the courts
solely through mediation and, if mediation is not successful, through binding

judgment upon the award rendered by the arbitrators may be entered by any court
having jurisdiction. Neither party will be liable to the other for punitive
damages for any such claim or dispute.

                                                             ASSOCIATE AGREEMENT

This Associate Agreement (this "Agreement") is made as of July 8, 1996 by and
between Perot Systems Corporation, a Delaware Corporation, or one of its
subsidiaries or affiliates (Perot Systems Corporation and all its subsidiaries
and affiliates are collectively referred to as "Perot Systems" and the
organization employing the Associate, which is Perot Systems Corporation
itself, will be referred to as "Company") and James Champy ("Champy"), an
individual who, subject to satisfaction of any conditions stated in his offer
of employment, will become an employee of Company beginning on August 12 , 1996
(the "Effective Date").

1.   Employment.

     (a) Subject to the terms and conditions specified in this Agreement,
Company hereby agrees to employ Champy on a full time basis (subject to Section
3) as Chairman of Perot Systems' Management Consulting Business ("Management
Consulting") reporting directly to Company's current Chief Executive Officer
("CEO") and Chairman of the Board (the "Chairman"), Morton H. Meyerson.  If
Morton H. Meyerson ceases to serve as CEO, Champy will report jointly to Morton
H. Meyerson and the new CEO as long as Morton H. Meyerson remains the Company
Chairman.   If Morton H. Meyerson ceases to serve as the Company Chairman,
Champy will report directly to the then current CEO.  The Company agrees that
during the term of this Agreement Champy shall at all times be one of the most
senior executive officers of the Company.

     (b) As Chairman of Management Consulting, Champy's responsibilities and
authority shall consist (subject to ultimate control of the CEO and the
Chairman) of the direction and control of Management Consulting, including
developing strategy and direction for Management Consulting, hiring senior
executives for Management Consulting and participating in general marketing
activities and consulting for key clients.  Champy agrees to perform these
responsibilities and other duties normally associated with such position,
subject to such legal and ethical policies and guidelines as may be reasonably
established from time to time by the Board of Directors (the "Board"), the
Chairman or the CEO of Company.

     (c) The term of Champy's employment by Company hereunder will commence on
the Effective Date and will continue until and unless terminated in accordance

2.   Compensation and Benefits.

     (a) During the term of this Agreement, Company will pay Champy (in
accordance with the Company's normal payroll policies) a salary of $41,666.67
per month, which salary the Board shall review at least once in each calendar
year to determine whether an upward adjustment is warranted (as so adjusted
from time to time, the "Base Salary"), plus a bonus payable as of the end of
each calendar year to be determined in accordance with the then current bonus
plan applicable to the most senior executive officers of the Company.

     (b) Champy will receive medical coverage, dependent medical coverage and
disability coverage on the same terms as the other most senior executive
officers of Company.  Champy will be entitled to indemnification and will
receive directors' and officers' liability insurance to the maximum extent
provided to other directors and most senior executive officers of Company.
Champy will be entitled to receive benefits related to travel, as established
or revised by Company from time to time for Company's CEO and Chief Operating
Officer ("COO").  Champy will receive life insurance coverage in the amount of
$1,000,000 on the same terms as provided to the Company's current Chairman, if
Champy submits to a physical examination and receives an insurability rating
that provides for no higher premium than that paid by Company for the current
Chairman; provided that, if Champy's premium would be higher than that paid by
Company for the current Chairman, Champy may obtain a lower amount of coverage,
so as to reduce the premium to that paid for the current Chairman, or may
obtain equivalent coverage by paying the difference between his actual rate and
the rate paid for the current Chairman.  Champy shall also receive other fringe
benefits, and be entitled to vacation time, consistent with the other fringe
benefits and vacation time afforded to the other most senior executive officers
of the Company.

     (c) Company will provide Champy office space, a full time assistant and
telephone and electronic equipment and services reasonably necessary or
appropriate to permit him to perform his duties.  Champy's office will be
located in Cambridge or Boston, Massachusetts, which will be the principal
location from which Champy will perform services hereunder.

     (d) Company shall reimburse Champy for all reasonable expenses incurred or
paid by Champy in connection with, or related to, the performance of his
duties, responsibilities or services under this Agreement in accordance with
Company's normal expense reimbursement policies applicable to its most senior
executive officers.

3.   Outside Activities.  While employed by Company, Champy will not (a)
engage in any other business activity or (b) work for or have any financial
interest in any business enterprise, including any sole proprietorship, without
Company's prior consent; provided, however, that Champy shall be permitted (i)
to make and maintain passive personal investments for himself, members of his
immediate family and any trust or custodial account for his or their benefit,
and (ii) participate in civic, charitable, religious and other not-for-profit
organizations so long as his activities pursuant to the forgoing clauses (i)
and (ii) do not unreasonably interfere with the performance by him of his
duties and responsibilities hereunder.  In addition, notwithstanding the
      
                                       2

4.   Certain Policies.  Champy will comply with all Perot Systems' policies that
are communicated to him from time to time, including but not limited to its
Standards and Ethical Principles.  Champy understands that Perot Systems'
policies are intended for general guidance only and that Perot Systems may
amend or cancel those policies at any time.  Champy will not knowingly engage
in or tolerate illegal or unethical conduct within Perot Systems.  Champy
agrees to be tested at Company's request, at any time or from time to time, to
detect drugs, controlled substances, alcohol or inhalants, by giving blood
samples, urine samples or both.

5.   Confidential Information.

     (a) Champy acknowledges that Perot Systems is continuously developing or
receiving Confidential Information, and that during his employment he will
receive Confidential Information from Perot Systems, its customers and
suppliers and special training related to Perot Systems' business
methodologies.  He further acknowledges and agrees that his employment by
Company creates a relationship of confidence and trust between the parties that
extends to all Confidential Information that becomes known to him.
Accordingly, Champy will not disclose or use any Confidential Information,
except in connection with the good faith performance of his duties as an
employee, and will take reasonable precautions against the unauthorized
disclosure or use of Confidential Information.  Upon Company's request, Champy
will execute and comply with a third party's reasonable agreement to protect
its confidential and proprietary information.  In addition, Champy will not
solicit or induce the unauthorized disclosure or use of confidential or
proprietary information for the benefit of Perot Systems.

     (b) For purposes of this Agreement, "Confidential Information" means all
written, machine-reproducable, 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 Champy develops
in the scope of his employment) that (i) Perot Systems or any of its customers
or suppliers treats as proprietary or confidential through markings or
otherwise, (ii) relates to Perot Systems 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 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 data, information or
material that is:  (i) approved by Company for unrestricted public disclosure;
(ii) known to Champy without obligations of confidentiality prior to the time
that he learns of such data, information or material as a result of his
employment by the Company; or (iii) is or becomes publicly known without a
breach of this Agreement.

6.   No Competition/ Non-Solicitation.  Champy acknowledges that, in the course
and as a result of employment with the Company, Champy will obtain special
training and knowledge and will come in contact with the Company's customers
and potential customers, which training,

                                       3

knowledge and contacts potentially could provide invaluable benefits to
competitors of the Company.  Accordingly, and in consideration of Company's
agreement to hire Champy hereunder, which Champy acknowledges is conditioned on
the covenants contained herein, Champy agrees that for one year after his
employment by Company ends, for any reason, except with the prior written
consent of Company, Champy will comply with the following covenants:

     (a) except for Exempted Activities (as defined below), Champy will not
solicit or perform (or assist a third party in soliciting or performing)
services (a "Restricted Solicitation or Performance"), as an employee,
independent contractor, subcontractor or otherwise, for any Person (including
any Persons known by Champy to be affiliates or subsidiaries of the specified
Person) that is or was a customer or prospect of the Company for which Champy
solicited business or performed services on behalf of the Company during the
two-year period prior to the Restricted Solicitation or Performance (a "PSC
Customer or Prospect"); and

     (b) Champy will not knowingly recruit or employ or knowingly assist any
Person in recruiting any person who is, or at any time within the preceding one
year was, an employee of the Company.

The following activities by Champy shall constitute "Exempted Activities" for
purposes of clause (a) above:

           (i)   soliciting or performing services for any of the Persons listed
      on Exhibit A (including subsidiaries and affiliates of such Persons);

           (ii)  the performance by Champy of consulting services or the like as
      an independent contractor working solely for himself and by himself other
      than for administrative and editorial support (or a business of which
      Champy is the owner of all of the equity and the sole non-administrative,
      non-editorial employee); provided, however, that the performance of such
      services by Champy for a PSC Customer or Prospect only shall constitute
      an Exempted Activity if Champy has obtained the written consent of the
      Company's Chairman or CEO, which consent shall not be unreasonably
      withheld;

           (iii) the presentation by Champy of speeches, seminars or the like
      as an independent contractor working solely for himself and (except as to
      participation on a panel or with a group of unrelated persons) by himself
      other than for administrative support (or a business of which Champy is
      the owner of all of the equity and the sole non-administrative employee)
      and publishing of books and articles by Champy; and

           (iv)  serving as a member of the faculty or administration of an
      academic or non-profit institution.

For purposes of this Agreement, "Person" includes an individual, corporation,
partnership, association, trust, unincorporated organization, governmental
entity, other entity or group.

If a court of competent jurisdiction finds any provision of this Section 6 to
be unreasonable, then that provision shall be considered to be amended to
provide the broadest scope of protection to Perot Systems that such court would
find reasonable and enforceable.

7.   Proprietary Rights.

     (a) Champy agrees to disclose to Company all works of authorship and
inventions that Champy produces, conceives or develops, working alone or
jointly with others while Champy is employed by Company, including all computer
programs, documents, and records, together with all related ideas, know-how and
techniques. Except as provided in Section 9, all copyrights, patent rights and
other intellectual property rights in and to all works of authorship and
inventions that Champy produces, conceives or develops while Champy is employed
by the Company, working alone or jointly with others, are intended to be and
will be owned solely by Company, whether or not they are produced using
Company's equipment, facilities, supplies or Confidential Information.

     (b) Except as provided in Section 9, Champy assigns to Company all of his
rights in and to all works of authorship and inventions that Champy produces,
conceives or develops, working alone or jointly with others while Champy is
employed by the Company, and waives all moral or similar rights therein. Champy
will sign, without additional compensation, all necessary documents and will
otherwise assist Company, at its expense, to apply for, register and enforce
all copyrights, patents and other intellectual property rights in works of
authorship and inventions assigned by Champy to the Company pursuant to this
Agreement.  Champy appoints Company as his attorney-in-fact for the sole
purpose of executing all necessary documents relating to the application for,
registration of, or enforcement of Company's copyrights, patents and other
intellectual property rights in works of authorship and inventions assigned by
Champy to the Company pursuant to this Agreement.  Notwithstanding the
foregoing, Champy does not assign works of authorship or inventions which (i)
he developed entirely on his own time without using Company's equipment,
facilities, supplies or Confidential Information, and (ii) do not relate to
either (A) Perot Systems' business, (B) Perot Systems' actual or demonstrably
anticipated research or development, or (C) work done by him for Perot Systems.

     (c) Company can waive the rights in any work of authorship or invention to
which it otherwise has rights under this Agreement only through a written
instrument signed by an officer of Company after Champy has materially
disclosed in writing the existence and nature of that work of authorship or
invention.

     (d) Champy will not disclose to Perot Systems or use for Perot Systems'
benefit any Third Party Intellectual Property.  "Third Party Intellectual
Property" means any confidential or proprietary information owned by any Person
other than Perot Systems.

8.   Termination.

     (a) Company may terminate Champy's employment under this Agreement at any
time for Cause or Substantial Misconduct.  "Cause" means termination of
employment for (i) a felony

                                       5
Associate Agreement                                             Revised (May 96)

<PAGE>   6

conviction of Champy for a crime involving moral turpitude; or (ii) actions by
Champy relating to his employment by the Company and constituting moral
turpitude, theft or dishonesty in a material matter.  "Substantial Misconduct"
means termination of employment for (i) a knowing and material breach by Champy
of any obligation under Sections 3, 5 or 7; (ii) actions involving a knowing
and material lack of business ethics or a knowing and material failure to
comply with Perot Systems' Standards and Ethical Principles; or (iii) a felony
conviction of Champy other than for a crime involving moral turpitude.  If
Company wishes to terminate Champy for Substantial Misconduct under clause (i)
or (ii) in the previous sentence, Company may only do so if Champy does not
substantially cure such breach within 15 days after receipt of notice from
Company specifying the breach, or, if such breach is not susceptible to a cure,
Champy does not within such 15 days (i) remedy the breach to the extent
possible; (ii) provide an appropriate apology; and (iii) agree in writing that
if he commits a similar breach in the future, such breach will constitute
Substantial Misconduct without any cure period.  In addition, before Company
may terminate Champy for Cause or Substantial Misconduct, Company shall give
Champy written notification of the proposed termination.  Champy shall have one
week from the date of the notice of the proposed termination to submit a
written statement to the Board concerning the proposed termination (in the case
of a termination for Substantial Misconduct under clauses (i) and (ii) the
one-week period shall not begin until the end of the 15-day cure period).  If
Champy fails to submit such a statement, his employment with Company shall
terminate automatically at the end of the one-week period.  In the event Champy
does submit such a statement within the one-week period, and the Board has not
decided to continue Champy's employment by the end of a second one-week period,
Champy's employment will terminate automatically at the end of such second
one-week period.

     (b) Company may terminate Champy's employment under this Agreement at any
time for any reason other than Cause or Substantial Misconduct upon 30 days'
prior written notice to Champy.  If on or before August 12, 1997, (i) Company
terminates Champy's employment for any reason other than Cause or Substantial
Misconduct or (ii) Champy is Constructively Terminated (as defined below), upon
such termination, Company will (A) pay Champy severance pay equal to Champy's
then current Base Salary for one year from the date of termination, to be paid
in semi-monthly payments, less appropriate withholdings pursuant to Company's
payroll practices; (B) continue all of Champy's benefits under Section 2(b)
until the expiration of such severance period; and (C) pay Champy any other
amounts due him hereunder that have accrued or been incurred prior to the date
of termination.  If after August 12, 1997, (i) Company terminates Champy's
employment for any reason other than Cause or Substantial Misconduct or (ii)
Champy is Constructively Terminated (as defined below), upon such termination,
Company will (A) pay Champy severance pay equal to Champy's then current Base
Salary for six months from the date of termination, to be paid in semi-monthly
payments, less appropriate withholdings pursuant to Company's payroll
practices; (B) continue all of Champy's benefits under Section 2(b) until the
expiration of such severance period; and (C) pay Champy any other amounts due
him hereunder that have accrued or been incurred prior to the date of
termination.  "Constructively Terminated" or "Constructive Termination" means
the occurrence of any of the circumstances set forth below, if within 90 days
after such occurrence, Champy delivers written notice to the Board stating that
he will terminate his employment with Company

                                       6

if such circumstance is not substantially cured within 30 days, and such
circumstance is not substantially cured within such 30-day period.

           (i)   Removal of Champy as Chairman of Management Consulting (unless
      such removal is in conjunction with a promotion accepted by Champy) or a
      material diminution, on a cumulative basis, in Champy's duties,
      authority, position, Base Salary or other compensation or benefits
      (excluding any diminution of bonus or other discretionary payments);

           (ii)  If Champy is not elected to the Board at the first scheduled
      Board meeting after the Effective Date or ceases to serve as a member of
      the Board other than as a result of (i) his death, permanent disability,
      resignation or refusal to serve on the Board; or (ii) his removal from
      the Board in connection with a termination of Champy's employment for
      Cause or Substantial Misconduct or Champy's resignation of employment
      with the Company;

           (iii) the relocation of Champy's offices, or the principal location
      at which he is to perform services hereunder, outside of
      Cambridge/Boston, Massachusetts; or

           (iv)  the material breach by the Company of any of its material
      covenants or agreements contained in this Agreement.

     (c) In the event a Change in Control of Company (as defined below) occurs
on or before August 12,  1997, and Champy's employment with Company is
terminated by either party (other than a termination by Company for Cause)
within one year after such Change in Control, upon such termination, Company
will (A) pay Champy severance pay equal to Champy's then current Base Salary
for one year from the date of termination, to be paid in semi-monthly payments,
less appropriate withholdings pursuant to Company's payroll practices; (B)
continue all of Champy's benefits under Section 2(b) until the expiration of
the severance period; and (C) pay Champy any other amounts due him hereunder
that have accrued or been incurred prior to the date of termination.  If a
Change in Control of Company (as defined below) occurs after August 12, 1997,
and Champy's employment with Company is terminated by either party (other than
a termination by Company for Cause) within one year after such Change in
Control, upon such termination, Company will (A) pay Champy severance pay equal
to Champy's then current Base Salary for six months from the date of
termination, to be paid in semi-monthly payments, less appropriate withholdings
pursuant to Company's payroll practices; (B) continue all of Champy's benefits
under Section 2(b) until the expiration of the severance period; and (C) pay
Champy any other amounts due him hereunder that have accrued or been incurred
prior to the date of termination

     (d) "Change in Control" of Company is defined to mean any of the following
events:

           (i)   The Company is merged, consolidated or reorganized into or with
      another corporation or other legal entity and as a result of such merger,
      consolidation or reorganization less than 50% of the combined equity
      interests or voting power of the then

                                       7
Associate Agreement                                             Revised (May 96)

<PAGE>   8

      outstanding securities of the remaining corporation or legal entity or
      its ultimate parent immediately after such transaction are received in
      respect of or in exchange for voting securities of the Company pursuant
      to such transaction;

           (ii)   The Company sells all or substantially all of its assets to
      any other corporation or other legal entity and, immediately following
      such sale, the equity owners of the Company prior to such sale own less
      than 50% of the combined equity interests or voting power of the then
      outstanding securities of such other corporation or legal entity or its
      ultimate parent; or

           (iii)  any person (including any "person" as such term is used in
      Section 13(d)(3) or Section 14(d)(2) of the Securities Exchange Act of
      1934, as amended (the "Exchange Act")) has become the beneficial owner
      (as the term "beneficial owner" is defined under Rule 13d-3 or any
      successor rule or regulation promulgated under the Exchange Act) of
      securities which, when added to any securities already owned by such
      person, represent in the aggregate (i) 50% or more, if the Company's
      common stock is not Publicly Traded (as defined in the Restricted Stock
      Agreement between the Company and Champy of even date herewith) at such
      time, or (ii) 40% or more, if the Company's common stock is Publicly
      Traded at such time, of the outstanding securities of the Company which
      are entitled to vote to elect directors.

provided, however, that notwithstanding subsection (1), (2) or (3) above, the
ownership or acquisition of securities by Swiss Bank Corporation ("SBC") or its
affiliates (subject to the limitations of any agreement between SBC or its
affiliates and Perot Systems) or Ross Perot or his affiliates or family members
or affiliates of his family will not constitute, or be deemed to cause, a
Change in Control.

     (e) In addition to Champy's other rights to terminate this Agreement, (i)
effective at the expiration of the first year of this Agreement, Champy may
terminate his employment under this Agreement upon written notice of such
termination given to Company at least 30 days' prior to the expiration of such
first year, and (ii) effective at any time after the expiration of the second
year of the term of this Agreement, Champy may terminate his employment under
this Agreement upon 30 days' prior written notice to the Company.   In the
event of a termination by Champy pursuant to this Section 9(e), Company will
have no further obligations to Champy hereunder, except for: (i) payment of
accrued Base Salary and provision of benefits pursuant to Section 2(b) through
the date of termination, (ii) payment of any other amounts due Champy hereunder
that have accrued or been incurred prior the date of termination; and (iii)
payments to Champy pursuant to Section 9.

     (f) If Champy brings a claim against Company or its directors, officers or
employees related to his employment by Company or termination thereof, he shall
concurrently return to Company any severance payments previously made to him
pursuant to this Agreement and Company's obligation to make additional
severance payments as provided in this Agreement shall be suspended pending the
outcome of such claim.  If Champy is not the prevailing party with respect to
such claim, Champy and Company will request the arbitrator or judge before

                                       8
Associate Agreement                                             Revised (May 96)

<PAGE>   9

whom the claim was brought to determine whether the claim was frivolous or
brought by Champy in bad faith (any such claim, a "Bad Faith Claim").  If the
judge or arbitrator determines that the claim brought by Champy was a Bad Faith
Claim, Champy will forfeit his right to any severance payments returned by him
to Company, any severance payments which have been suspended and any future
severance payments.  If the judge or arbitrator determines that the claim
brought by Champy was not a Bad Faith Claim, the Company promptly will pay to
Champy all severance pay provided for under this Agreement plus simple interest
at 8% per annum from the date Champy brings the claim (and returns previously
paid severance payments, if any) to the date Company tenders such severance
payments to Champy.

9.   Speeches and Publications.  During the term of this Agreement, Champy may
(subject to Section 5) prepare and participate in writing and publishing books,
newspaper columns and articles for general distribution to the public (as
opposed to for use primarily in connection with Perot Systems' clients or
prospective client projects).  Such books, newspaper columns and articles of
general distribution are referred to herein as "Publications."  Champy shall
notify the Company reasonably promptly upon his participation in preparing
books, newspaper columns or articles that constitute Publications under this
Section 9.  Champy will own the copyright in connection with any Publications.
During the term of this Agreement, Champy will determine the timing and method
of any publishing, sale, lease or distribution of any Publication, but will
consult with the CEO or the CEO's designee in connection with these matters and
will take into account the reasonable requests and interests of the Company as
to these matters.  After the termination of this Agreement, Company shall be
entitled to distribute copies of the Publications under arrangements with the
current or future publisher as determined by Champy or the Company; provided,
however, the Company shall not be entitled to make any editorial modifications
to or based on such Publications without Champy's consent  In connection with
preparing any Publications while Champy is employed by the Company, Company
agrees to provide Champy with secretarial assistance and pay other reasonable
expenses, including expenses relating to editorial/writing and marketing
assistance.  Company shall be entitled to receive all royalty income generated
by any Publication, including advances and publisher assistance in writing the
Publication, until Company has been reimbursed for all out-of-pocket expenses
and costs paid by Company to third parties (other than compensation costs of
Perot Systems' employees) relating to the Publication. After Company has been
reimbursed for all such expenses and costs, Company and Champy will share in
the royalty income generated from the Publication (whether arising during or
after the term of this Agreement) with each party receiving fifty percent of
the royalty income. After the term of this Agreement, Champy will not interfere
with customary efforts by either the Company or the publisher to promote any
Publication in order to commercially exploit the value thereof.

During the term of this Agreement, Champy shall also be entitled to prepare and
deliver speeches.  To the extent Champy receives income from third parties for
speeches and similar events while Champy is employed by the Company, such
income will be the property of the Company, and Champy will submit payment to
the Company for such income promptly upon receipt of such income from third
parties.  To the extent Champy receives income from third parties for speeches
and similar events after Champy ceases to be employed by the Company, such
income will be the property of Champy.

     (a) Promptly after the end of his employment, Champy will return to the
Company all tangible forms of Confidential Information and all equipment,
records and other physical property in his possession or under his control that

excluding any conflicts of law provisions thereof.

herewith, including any related loan agreements with NationsBank of Texas, N.A.

13.  Withholding.  Company may withhold from any amounts payable under this
Agreement all federal, state, city or other taxes as may be required pursuant
to any law or government regulation or ruling.

14.  ARBITRATION.  ANY DISPUTE ARISING BETWEEN CHAMPY AND PEROT SYSTEMS UNDER

AMERICAN ARBITRATION ASSOCIATION (EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN
THIS AGREEMENT) BEFORE A SINGLE ARBITRATOR.  SUCH ARBITRATOR SHALL BE SELECTED
BY AGREEMENT OF CHAMPY AND PEROT SYSTEMS OR, IF THEY ARE UNABLE TO AGREE UPON
SUCH SINGLE ARBITRATOR, BY THE WASHINGTON, D.C. OFFICE OF THE AMERICAN
ARBITRATION ASSOCIATION.  ANY AWARD RENDERED BY THE ARBITRATOR SHALL BE FINAL
AND BINDING UPON THE PARTIES HERETO.  JUDGMENT UPON THE AWARD MAY BE ENTERED IN
ANY COURT OF COMPETENT JURISDICTION.  THE ARBITRATOR SHALL BE ALLOWED TO
DETERMINE THE COSTS OF ARBITRATION (INCLUDING THE PARTIES' LEGAL AND OTHER
COSTS AND EXPENSES) AND ALLOCATE WHICH PARTY SHOULD BEAR THE COSTS OF
ARBITRATION.  THE ARBITRATOR SHALL HAVE NO AUTHORITY TO AWARD DAMAGES IN EXCESS
OR IN CONTRAVENTION OF THIS AGREEMENT.  NEITHER PARTY WILL BE LIABLE TO THE
OTHER FOR SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OR LOST PROFITS FOR ANY
CLAIMS ARISING OUT A BREACH OR ALLEGED BREACH OF THIS AGREEMENT, AND CHAMPY AND
PEROT SYSTEMS EACH HEREBY WAIVES ANY CLAIMS AGAINST THE OTHER FOR SUCH DAMAGES.
NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 14 SHALL BE CONSTRUED TO
LIMIT THE RIGHT OF A PARTY TO SEEK INJUNCTIVE RELIEF WITH RESPECT TO ANY ACTUAL
OR THREATENED BREACH OF THIS AGREEMENT FROM A COURT OF COMPETENT JURISDICTION.

specifically referenced herein (together with the Restricted Stock Agreement

the entire agreement between Company and Champy with respect to the subject
matter hereof.  Such agreements supersede any prior discussions, promises, or

                           RESTRICTED STOCK AGREEMENT

THIS AGREEMENT, dated as of July 8, 1996, is by and between Perot Systems
Corporation ("Perot Systems"), a Delaware corporation and James Champy
("Participant").

                                  WITNESSETH:

WHEREAS, Perot Systems has adopted the Perot Systems Corporation Restricted
Stock Plan (the "Plan"), a copy of which is attached hereto as Attachment E, to
enable employees of Perot Systems and its subsidiaries, if any (collectively,
the "Company") 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 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:

     the respective meanings indicated as follows:

     (a)  "Holding Period" shall mean, (i) for one-half of the shares of Vested
          Stock vesting on a particular Vesting Date the period of time
          commencing on the Vesting Date upon which such shares become Vested
          Stock and ending two years thereafter, and (ii) for the other
          one-half of the shares of Vested Stock vesting on a particular
          Vesting Date, a period of time consisting of the day upon which such
          shares become Vested Stock; provided, however, that there shall be no
          Holding Period for any shares of Vested Stock from and after the date

          by the Company or Participant) for any reason.

     (b)  "Market Value" of a share of Restricted Stock on a given date shall
          mean (i) if the Common Stock is Publicly Traded the closing sale
          price for Common Stock 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 average of the closing bid and ask prices on such date
          or, if no closing bid  and ask prices are available for such date,
          the average of the closing bid and ask prices on the most recent
          prior date for which such bid and ask prices are available, or (ii)

2.   Purchase and Sale.  Subject to the terms, conditions, and restrictions set
     forth in this Agreement, on the Effective Date under the Associate
     Agreement between Perot Systems and Participant of even date herewith (the
     "Associate Agreement") Perot Systems shall sell to Participant, and
     Participant shall purchase from Perot Systems, for a purchase price of
     $2.50 per share, payable on the Effective Date, the number of shares of
     Common Stock specified on Attachment A hereto, which shares shall vest to
     Participant in accordance with the vesting schedule set forth on
     Attachment A hereto for so long as Participant is an employee of the
     Company and as follows:





                                                                    Page 2 of 16
<PAGE>   3
     (a)  If Company terminates Participant's employment effective on or before
          August 12, 1997, for any reason other than Cause or Substantial
          Misconduct (each as defined in the Associate Agreement), the
          Restricted Stock scheduled to vest on the Vesting Dates in 1997 and
          1998 will vest on such Vesting Dates notwithstanding such
          termination.

     (b)  If (i) Participant's employment with Company is terminated by Company
          for any reason other than Cause or Substantial Misconduct effective
          after August 12, 1997 and on or before August 12, 1998 or (ii)
          Participant is Constructively Terminated (as defined in the Associate
          Agreement) on or before August 12, 1998, then the Restricted Stock
          scheduled to vest on each Vesting Date to and including the Vesting
          Date in 2000 will vest on such Vesting Dates (to the extent not
          previously vested) notwithstanding such termination.  If (i)
          Participant's employment with Company is terminated by Company for
          any reason other than Cause or Substantial Misconduct effective after
          August 12, 1998 or (ii) Participant is Constructively Terminated
          after August 12, 1998, then the Restricted Stock scheduled to vest on
          each Vesting Date up to the date occurring two years after the date
          of termination will vest on such Vesting Dates (to the extent not
          previously vested) notwithstanding such termination.

     (c)  If  a Change in Control (as defined in the Associate Agreement)
          occurs on or before August 12, 1998, and Champy's employment with the
          Company is terminated by either party within one year after such
          Change in Control (other than a termination by the Company for
          Cause), then the Restricted Stock scheduled to vest on each Vesting
          Date to and including the Vesting Date in 2000 will vest on such
          Vesting Dates (to the extent not previously vested) notwithstanding
          such termination.  If a Change in Control occurs after August 12,
          1998, and Champy's employment with the Company is terminated by
          either party within one year after such Change in Control (other than
          a termination by the Company for Cause), then the Restricted Stock
          scheduled to vest on each Vesting Date up to the date occurring two
          years after the date of termination will vest on such Vesting Dates
          (to the extent not previously vested) notwithstanding such
          termination.

     (d)  If Participant's employment is terminated as a result of
          Participant's death or disability, then the Restricted Stock
          scheduled to vest on each Vesting Date to and including the Vesting
          Date one year following such termination will vest on such Vesting
          Dates (to the extent not previously vested) notwithstanding such
          termination.

     If a termination occurs that is covered by the provisions of both
     subsection (a) and subsection (c) above, the terms of subsection (c) above
     shall govern.

3.   Restrictions on Transfer.  All shares of Restricted Stock shall be subject
     to the following restrictions on transfer unless the Company shall
     otherwise agree in writing:

     (a)  Shares of Unvested Stock may not be sold or otherwise transferred.

     (b)  Shares of Vested Stock may not be sold or otherwise transferred
          during the Holding Period for those shares.





                                                                    Page 3 of 16
<PAGE>   4
     (c)  For the benefit of Perot Systems and the underwriters of the initial
          underwritten public offering of Perot Systems Common Stock registered
          under the Securities Act of 1933, as amended (the "Securities Act"),
          Participant will not effect any transfer of Vested Stock without the
          written consent of the representatives of such underwriters for the
          same period as the underwriters request from the top five executive
          officers of Perot Systems (as designated by the CEO of Perot
          Systems), but in no event for a period of more than 270 days.

     (d)  Shares of Vested Stock may not be sold or otherwise transferred after
          the Holding Period for those shares and prior to the date the Common
          Stock is Publicly Traded unless Participant has given Perot Systems
          any notice required under Section 4 and Perot Systems has waived or
          failed to exercise its option to purchase those shares pursuant to
          Section 4 hereof.

     (e)  Notwithstanding the foregoing restrictions on transfer, Participant
          may transfer, while he is alive or as a distribution upon his death,
          all or a portion of the Restricted Stock to a maximum of five
          transferees, but only if each transferee is Participant's spouse,
          descendant or a trust for their benefit.  Any such transfer must be
          effected pursuant to documentation reasonably acceptable in form and
          substance to Perot Systems, and such documentation must provide that
          the Restricted Stock transferred remains subject to all of the
          vesting provisions, transfer restrictions, repurchase options and
          other provisions of this Agreement, in each case as if such
          Restricted Stock continued to be held by Participant.  Without
          limiting the generality of the foregoing, a transferee under this
          paragraph will hold the Restricted Stock subject to Perot Systems'
          repurchase options and other rights under Section 4, Section 6 and
          Section 9 hereof.

     Perot Systems shall not be obligated to recognize any purported sale or
     other transfer of Restricted 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.   Options to Purchase Vested Stock.  Unless and until waived by Perot
     Systems and regardless of whether or not Participant is still employed by
     the Company, Perot Systems shall have the following options to purchase
     Vested Stock:

          If, after the Holding Period therefor and prior to the date the Common
          Stock is Publicly Traded, Participant, or any subsequent holder of
          Vested Stock, desires or is obligated to sell or otherwise transfer
          any shares of Vested Stock (other than a transfer  upon Participant's
          death), the holder of such shares shall give Perot Systems written
          notice of the proposed sale or transfer, including the identity of the
          proposed purchaser or transferee, and, for a period of 30 days after
          receipt of such notice, Perot Systems shall have the option to
          purchase for cash any or all of such shares at the Market Value
          thereof.





                                                                    Page 4 of 16
<PAGE>   5
5.   Manner of Stock Buy Back.  Whenever Perot Systems has a right to buy back
     shares of Restricted Stock pursuant to this Agreement, 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 buy back under Section 4 or Section 9,
     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
     ten days, any previously issued certificate representing shares of
     Restricted 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 endorsed certificate or stock power is not tendered within ten days,
     Perot Systems may cancel any outstanding certificate representing shares
     to be bought back (subject to Perot Systems issuing a new certificate as
     to shares included in the outstanding certificate but not subject to the
     buy back right exercised by Perot Systems).  Perot Systems is required to
     tender the purchase price within ten days of the tender of the shares.  If
     the person from whom the shares are to be bought back has not complied
     with an obligation to return a certificate and stock power representing
     shares to be bought back, however, Perot Systems is not required to tender
     the purchase price until ten days after the certificate is returned or ten
     days after it cancels the certificate (as provided above in this Section
     5), whichever occurs first.

6.   Termination of Employment.  In the event that, during the Vesting Period,
     Participant's employment with the Company is voluntarily or involuntarily
     terminated for any reason, Perot Systems shall be entitled, by notice to
     Participant within 90 days after such termination, to exercise the rights
     specified in Section 9(b) below, but only as to Unvested Stock, other than
     Unvested Stock that will vest at or following such termination pursuant to
     Section 2(a), (b), (c) or (d) hereof.

7.   Stock Repurchase.  If Participant's employment is terminated for any
     reason, at Participant's option, Perot Systems shall repurchase all or
     such portion as shall be requested by Participant of the Restricted Stock
     purchased and still held by Participant at the price paid by Participant
     (subject to adjustment in the event of stock splits, stock dividends,
     combinations and recapitalizations affecting such 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,
     minus the amount or value, as applicable, of any dividends or
     distributions paid on such Restricted Stock to and retained by Participant
     pursuant to Section 11, provided Participant gives Perot Systems written
     notice of his election to exercise such option and tenders to Perot
     Systems any previously issued certificate representing shares of
     Restricted Stock to be bought back, duly endorsed in blank or having a
     duly executed stock power attached in proper form for transfer, within 30
     days of the date of termination.  Perot Systems is required to tender the
     purchase price within ten days of the tender of the shares to it.

8.   Competition.  Participant acknowledges that, 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 customers and
     potential customers, which training, knowledge and contacts could provide
     invaluable benefits to competitors of the Company.





                                                                    Page 5 of 16
<PAGE>   6
     Accordingly, and in consideration of Perot Systems' agreement to issue
     Restricted Stock to Participant hereunder, which Participant acknowledges
     is conditioned on the covenants contained herein, Participant agrees that
     Perot Systems shall be entitled to exercise the rights specified in
     Section 9 below in the event that, during the time Participant is employed
     by the Company or within one year thereafter, except with the prior
     written consent of the Company, Participant, either directly or
     indirectly, does any of the following:

     (a)  except for Exempted Activities (as defined below), solicits or
          performs (or assists a third party in soliciting or performing)
          services (a "Restricted Solicitation or Performance"), as an
          employee, independent contractor, subcontractor or otherwise (other
          than as an employee of the Company), for any Person (including any
          Persons known by Participant to be affiliates or subsidiaries of the
          specified Person) that is or was a customer or prospect of the
          Company for which Participant solicited business or performed
          services on behalf of the Company during the two-year period prior to
          the Restricted Solicitation or Performance (a "PSC Customer or
          Prospect");

     (b)  knowingly recruits or employs or knowingly assists any Person in
          recruiting any person who is, or at any time within the preceding one
          year was, an employee of the Company; and

     (c)  provides services to, or otherwise is associated with, as an
          employee, independent contractor, subcontractor or otherwise (except
          as an employee of the Company), any of the companies or divisions
          listed on Attachment C attached hereto and their more than 50% owned
          subsidiaries (cumulatively the "Named Competitors").  Upon
          termination of Participant's employment with Company for any reason,
          Perot Systems will have ten days to add up to six additional Named
          Competitors to the list set forth on Attachment C by notice to
          Participant.  Notwithstanding the foregoing, this Section 8( c) will
          not apply if Participant's employment is Constructively Terminated,
          terminated within one year following a Change in Control or
          terminated by Company other than for Cause.

      The following activities by Participant shall constitute "Exempted
      Activities" for purposes of clause (a) above:

           (i)    soliciting or performing services for any of the Persons
                  listed on Exhibit A to the Associate Agreement (including
                  subsidiaries and affiliates of such Persons);

           (ii)   the performance by Participant of consulting services or the
                  like as an independent contractor working solely for himself
                  and by himself other than for administrative and editorial
                  support (or a business of which Participant is the owner of
                  all of the equity and the sole non-administrative,
                  non-editorial employee); provided, however, that the
                  performance of such services by Participant for a PSC
                  Customer or Prospect only shall constitute an Exempted
                  Activity if Participant has obtained the written consent of
                  the Company's Chairman or CEO, which consent shall not be
                  unreasonably withheld;





                                                                    Page 6 of 16
<PAGE>   7
           (iii)  the presentation by Participant of speeches, seminars or the
                  like as an independent contractor working solely for himself
                  and (except as to participation on a panel or with a group of
                  unrelated persons) by himself other than for administrative
                  support (or a business of which Participant is the owner of
                  all of the equity and the sole non-administrative employee)
                  and publishing of books and articles by Participant; and

           (iv)   serving as a member of the faculty or administration of an
                  academic or non-profit institution.

     If any provision of this Section 8 should be found by any court of
     competent jurisdiction to be unreasonable by reason of its being too broad
     as to the period of time, territory, and/or scope, then, and in that
     event, such provision shall nevertheless remain valid and fully effective,
     but shall be considered to be amended so that the period of time,
     territory, and/or scope set forth shall be changed to be the maximum
     period of time, the largest territory, and/or the broadest scope, as the
     case may be, which would be found reasonable and enforceable by such
     court.

9.   Rights Upon Termination or Competition.

     (a)  If Participant has engaged in any conduct prohibited by Section 8 or
          if Participant's employment was terminated by the Company for Cause
          (as defined in the Associate Agreement), Perot Systems will have the
          right for 150 days after the Committee discovers the relevant facts
          (but in no event later than two years after the date on which
          Participant ceased to be an employee of the Company) to:

           (i)    cancel any remaining vesting that has not yet occurred, but
                  is scheduled to occur in the future under Section 2(a), (b),
                  (c) or (d) hereof;

           (ii)   require Participant to sell to Perot Systems all or any part
                  of the Restricted Stock (both Vested Stock and Unvested
                  Stock) then held by Participant, at the price per share paid
                  by Participant (subject to adjustment in the event of stock
                  splits, stock dividends, combinations and recapitalizations
                  affecting such 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 5 above, minus the amount or value,
                  as applicable, of any dividends or distributions paid on such
                  Restricted Stock to and retained by Participant pursuant to
                  Section 11; and

           (iii)  if any shares of Restricted Stock have been sold or otherwise
                  transferred by Participant (including any sale to the
                  Company), require Participant to pay to Perot Systems an
                  amount in cash with respect to each share of Restricted Stock
                  not still so held equal to (i) in the case of a sale or
                  transfer to a non-affiliate in a bona fide, arms length
                  transaction, the value of the net proceeds received by

                  on the first date on which such share is no longer held by
                  Participant (or transferees under Section 3(e)), less in
                  either case the price paid by Participant for such share
                  (subject to adjustment in the event of stock splits, stock
                  dividends, combinations and recapitalizations affecting such
                  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
                  5 above, minus the amount or value, as applicable, of any
                  dividends or distributions paid on such Restricted Stock to
                  and retained by Participant pursuant to Section 11;

          provided that (i) the total number of shares of Restricted Stock as
          to which future vesting is canceled pursuant to subsection (i), plus
          (ii) the total number of shares of Restricted Stock that are
          repurchased by PSC pursuant to subsection (ii), plus (iii) the total
          number of shares of Restricted Stock with respect to which

          (iii), may not exceed the lesser of fifty percent (50%) of the Vested
          Stock or 100,000 shares (as adjusted to reflect any stock split,
          stock dividend or similar event affecting the total number of shares
          of Common Stock outstanding).  Perot Systems will exercise its
          remedies under this Section 9 in the order of subsections (i) through
          (iii), above, until the foregoing share limit is reached.

     (b)  If and when Perot Systems is entitled to exercise the rights
          specified in this Section 9, as provided in Section 6 above, then,
          upon the demand of Perot Systems, Participant shall sell to Perot
          Systems all or any part of the Unvested Stock then held by
          Participant, other than Unvested Stock that will vest at or following
          termination pursuant to Section 2(a), (b), (c) or (d), at the price
          per share paid by Participant (subject to adjustment in the event of
          stock splits, stock dividends, combinations and recapitalizations
          affecting such 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 5
          above, minus the amount or value, as applicable, of any dividends or
          distributions paid on such Unvested Stock to and retained by
          Participant.

10.  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 he will not 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 from
     Participant 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 reasonably
     deem necessary or advisable.

11.  Stock Certificate. Promptly upon the occurrence of each Vesting Date,
     Perot Systems will issue and deliver to Participant certificates
     representing any shares of Vested Stock held by Participant.  Perot
     Systems may require that any certificates or other property representing





                                                                    Page 8 of 16
<PAGE>   9
     shares of Unvested Stock remain in the possession of the Company or an
     escrow agent designated by the Committee.  Each certificate representing
     Vested Stock or Unvested Stock shall bear such legends as are provided on
     Attachment D to this Agreement or as are required under applicable
     securities laws.  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 Unvested Stock, whether resulting from a subdivision, combination or
     reclassification of the Unvested Stock of any issuer thereof or received
     in exchange for Unvested 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 Unvested Stock or received in
     payment of the principal of or in redemption of the Unvested Stock (either
     at maturity, upon call for redemption or otherwise), shall remain in the
     possession of Perot Systems.

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

13.  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 and do not increase Participant's
     obligations under this Agreement.

14.  Participant's Representations and Warranties.  Participant represents and
     warrants that he is an "accredited investor" as that term is defined in
     Rule 501 of Regulation D under the Securities Act by virtue of the fact
     that Participant (i) had individual income in excess of $200,000 in each
     of the last two calendar years and reasonably expects to have an
     individual income in excess of $200,000 in the current calendar year; (ii)
     had joint income with his spouse in excess of $300,000 in each of the last
     two calendar years and reasonably expects to have a joint income in excess
     of $300,000 in the current calendar year; or (iii) has an individual net
     worth, or has joint net worth with his spouse, in excess of $1,000,000.

     shall be addressed to Participant at the most recent address for

     ASSOCIATION.  ANY AWARD RENDERED BY THE ARBITRATOR SHALL BE FINAL AND

     OTHER COSTS AND EXPENSES) AND ALLOCATE WHICH PARTY SHOULD BEAR THE COSTS
     OF ARBITRATION.  THE ARBITRATOR SHALL HAVE NO AUTHORITY TO AWARD DAMAGES
     IN EXCESS OR IN CONTRAVENTION OF THIS AGREEMENT.  NEITHER PARTY WILL BE
     LIABLE TO THE OTHER FOR SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OR LOST
     PROFITS FOR ANY CLAIMS ARISING OUT OF A BREACH OR ALLEGED BREACH OF THIS
     AGREEMENT, AND PARTICIPANT AND PEROT SYSTEMS EACH HEREBY WAIVES ANY CLAIMS
     AGAINST THE OTHER FOR SUCH DAMAGES.  NOTWITHSTANDING THE FOREGOING,

     party may be entitled.

19.  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 shall not be affected thereby.





                                                                   Page 10 of 16

     substantially all of the Common Stock issued to Perot Systems' employees

     offered to such employees or executives as a group.

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.

                                July 8, 1996


Mr. James Champy
330 Beacon Street
Boston, MA  02108

Dear Jim:

You (Champy) and Perot Systems Corporation, a Delaware corporation (PSC),
propose to enter into an Associate Agreement and a Restricted Stock Agreement,
both of even date herewith.  PSC has agreed to the matters set forth below in
this letter agreement in order to induce Champy to enter into the Associate
Agreement and Restricted Stock Agreement.

PSC agrees to indemnify Champy and hold Champy harmless from and against any
and all claims, losses, damages, liabilities, costs and expenses (including
reasonable attorneys fees, except as otherwise specifically provided below)
(collectively, Liabilities and Costs) arising out of or relating to the
employment of Champy by PSC or actions taken by Champy as an employee of PSC
constituting or being alleged to constitute a breach of any employment,
confidentiality, noncompetition, nonsolicitation or similar agreement between
Champy and Computer Sciences Corporation and/or any subsidiary or affiliated
company of Computer Science Corporation (collectively CSC).

If any claim is asserted by CSC for which Champy desires to seek
indemnification from PSC pursuant to this letter agreement, Champy shall
promptly notify PSC thereof (although the failure of Champy to give such notice
shall not relieve PSC from its obligations hereunder except to the extent PSC
is prejudiced thereby).  PSC shall thereupon assume the defense of such claim
with counsel selected by PSC and reasonably satisfactory to Champy.  PSC shall
control the defense and settlement of any such claim; provided, however, that
Champy may participate in such defense with counsel of his own choosing and at
his own expense; and provided further, however, that PSC shall not enter into
any settlement that imposes any liability or obligation on Champy without
Champys prior written consent.

This letter agreement is binding upon and shall inure to the benefit of PSC and
Champy and their respective heirs, successors and assigns; provided, however,
that neither Champy nor PSC may assign its rights or delegate its obligations
under this letter agreement without the prior written consent of the other. 
All notices hereunder shall be given in the manner specified in the 

PSC acknowledges that Champy has provided PSC with copies of (i) the Major
Inside Stockholder Non-Competition Agreement between Champy and CSC dated as of
September 6, 1988 and (ii) the form of agreement between Index Systems, Inc.
and its employees of which Champy believes he executed a counterpart but is
unable to locate a copy thereof.  To the extent that the disclosure in this
paragraph is inconsistent with the last sentence of Section 3 of the Associate
Agreement, this paragraph amends and supersedes such sentence.

Associate Agreement.  This letter agreement shall be construed and enforced in
accordance with the laws of the State of Texas.  Any dispute between Champy and
PSC hereunder shall be subject to arbitration in accordance with Section 14 of
the Associate Agreement.

                                             Very truly yours,
                                         
                                             PEROT SYSTEMS CORPORATION
                                         
                                         
                                             By: /s/ MORTON H. MEYERSON

                               PROMISSORY NOTE


                                                                   June 17, 1996
$125,000.00



FOR VALUE RECEIVED, Guillermo G. Marmol ("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 one hundred twenty-five thousand
dollars ($125,000.00), payable, along with interest calculated at eight percent
per annum (8%), on or before June 17, 1999, 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
June 17, 1997.

       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 AssociateGs employment
with the Company or any subsidiary of the Company, for any reason, with or
without cause, or (ii) on the one year anniversary after common stock of the
Company, or any successor company, or stock of the type issued in exchange for
any common stock of the Company pursuant to a merger or otherwise, is publicly
traded on a stock exchange or the NASDAQ.  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
to 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.

       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.
<PAGE>   2
       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 June 17, 1996, by
and between Perot Systems Corporation, a Delaware corporation ("PSC"), and
Guillermo G. Marmol ("Pledgor").

       WHEREAS, PSC has granted Pledgor the option to purchase 100,000 shares
of PSC's common stock pursuant to a Restricted Stock Agreement dated as of June
17, 1996 (the "Restricted Stock Agreement");

       WHEREAS, PSC has extended credit to Pledgor and may extend additional
credit pursuant to the terms of a Promissory Note, dated as of the date hereof,
in the amount of one hundred twenty-five thousand dollars ($125,000) to finance
in part the acquisition of the Restricted Stock purchased pursuant to the
Restricted Stock Agreement (the "Note");

       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 Note, 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 Note; (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 Note, 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 Note 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 Note, 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.





                                     Page 6
<PAGE>   7
       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.

                           [PEROT SYSTEMS LETTERHEAD]

NationsBank of Texas, N.A.                             Mr. Guillermo G. Marmol

Attn: Ms. Joanne Gruber

         Re: Perot Systems Class A Common Stock Purchase

Dear Madam or Sir:

1.       The purpose of this letter is to provide for the agreement among Perot
         Systems Corporation ("PSC"), NationsBank of Texas, N.A.
         ("NationsBank") and Guillermo G. Marmol ("Associate") with respect to
         the purchase by Associate of one hundred thousand (100,000) shares
         (the "Shares") of Perot Systems Class A Common Stock ("Common Stock"),
         where some of the payment price for such Shares is being borrowed by
         Associate from NationsBank. The Shares are being purchased  from PSC
         pursuant to the Restricted Stock Agreement, dated as of June 17, 1996,
         between PSC and Associate (the "Stock Agreement").

2.       Each of the parties recognizes that Associate is obtaining funding
         from NationsBank in the original principal amount of $125,000 (the "NB
         Principal") pursuant to a promissory note, dated as of June 17, 1996,
         by Associate payable to the order of NationsBank (the "NB Promissory
         Note"), secured by a security agreement of even date with the NB
         Promissory Note (the "NB Security Agreement"). In addition, each of
         the parties recognizes that Associate is obtaining funding from PSC
         (in the original principal amount of $125,000 (the "PSC Principal")
         pursuant to a promissory note, dated as of June 17, 1996, executed by
         Associate payable to the order of PSC (the "PSC Promissory Note") and
         secured by a pledge agreement of even date with the PSC Promissory
         Note (the "PSC Pledge Agreement").

3.       Each of the parties hereby agrees that if PSC repurchases any Shares
         from Associate pursuant to the Stock Agreement, that it will
         distribute the repurchase price to PSC and to NationsBank pro-rata in
         accordance with the relative amounts of the unpaid NB Principal and
         the PSC Principal (if any) to apply to any amounts outstanding under
         the NB Promissory Note and under the PSC Promissory Note (if any).
         When PSC has been paid in full under the PSC Promissory Note (if any)
         it will send the entire balance of the repayment directly to 
         NationsBank regardless of the size of that amount (and even if in
         excess of the NationsBank Principal), unless and until it receives a
         signed authorization from Associate and NationsBank instructing it to
         send any additional funds directly to Associate.

4.       If, by the later of June 30, 1998 or the date of the maturity of the
         NB Promissory Note, PSC has not completed an initial public offering
         (the "IPO") whereby the Common Stock (or any successor security) is
         listed on a registered national securities exchange or approved for
         quotation in the National Association of Securities Dealers Automated
         Quotation System, then PSC will, within thirty days of NationsBank's
         written request, purchase the outstanding NB Promissory Note from
         NationsBank, for the then outstanding principal (which shall never
         exceed the original NB Principal) plus accrued but unpaid interest
         thereunder. In connection with such sale, NationsBank will endorse
         without recourse the NB Promissory Note to the order of PSC, transfer
         to PSC good title to the NB Security Agreement, under which the Shares
         shall be pledged, deliver any and all Shares in its possession owned
         by Associate, along with any signed stock powers thereto, and which
         Shares shall be free and clear of additional liens and encumbrances
         created by, through, or under NationsBank other than the NB Security
         Agreement, which shall be assigned to PSC.

5.       If the Associate sells a portion of the Shares as part of the IPO or
         thereafter (with NationsBank's and PSC's consent, if needed), then
         Associate agrees to use the sale proceeds (after estimated income tax)
         to prepay the NB Promissory Note and the PSC Promissory Note, in the
         same manner as provided in the third paragraph of this letter until
         principal and interest under both Notes have been paid in full.

6.       If the IPO occurs before the maturity of the NB Promissory Note but
         the Associate wishes to retain ownership of all Shares of publicly
         traded stock, the Associate will agree to collateralize the NB
         Promissory Note with such PSC vested Shares or other acceptable
         marketable securities that have a market value equal to or exceeding
         150% of the loan balance outstanding under the NB Promissory Note, and
         NationsBank and the Associate will execute a
<PAGE>   3
NationsBank of Texas, N.A.
- --------------------------
Page 3

         NationsBank collateral maintenance agreement that will control the
         continuing need for shares pledged as collateral and any adjustments
         thereto. This paragraph will not affect the PSC Promissory Note or the
         PSC Pledge Agreement. PSC will give notice to NationsBank from time to
         time of the principal outstanding under the PSC Promissory Note.

7.       The parties agree that Associate will execute both the NB Security
         Agreement and the PSC Pledge Agreement.  Associate agrees to execute a
         stock power in blank for each certificate evidencing any of the Shares
         and to deliver all such certificates with stock powers to PSC or
         NationsBank as appropriate (after the IPO, NationsBank will hold the
         certificates representing vested Shares to the extent needed under
         Paragraph 6).  Notwithstanding anything in those agreements to the
         contrary, the parties agree that NationsBank and PSC will both have a
         security interest in the Shares and whichever of PSC or NationsBank
         holds such Shares under the PSC Pledge Agreement or the NB Security
         Agreement shall hold the Shares for the benefit of both and PSC and
         NationsBank will cooperate with one another to enforce their
         respective rights under the NB Security Agreement and the PSC Pledge
         Agreement, and will share in any proceeds as set forth herein, until
         the amounts due under one of the PSC or NB Promissory Notes have been
         paid in full, and thereafter the balance will revert to the holder of
         the other Promissory Note until the amounts due under that Promissory
         Note have been paid in full except all proceeds received from the sale
         by NationsBank or by sale with NationsBank's consent of PSC publicly
         held shares subsequent to the IPO shall first be applied to payment of
         debt owed under the NB Promissory Note before any amounts shall revert
         to or be distributed to PSC. The Associate shall not be deemed to have
         violated either the PSC Pledge Agreement or the NB Security Agreement,
         or to have breached any representations, warranties or covenants
         therein, solely by virtue of signing both Agreements.

         By signature below, Associate irrevocably authorizes PSC and
NationsBank to make the payments, as provided in this letter, and agrees to
indemnify and hold PSC and NationsBank harmless against any loss, damage or
claim in connection with making payments as provided above.

         For purposes of notice under this letter, the parties' addresses shall
be deemed the addresses as provided above in this letter, unless the other
parties receive written notice, at least 15 days in advance, of a new address.

                Base Rate or Other Rate increases. Any increase will take form of [ ] higher payment amounts, or [ ] a larger amount
                due at maturity. For this Promissory Note, the Interest Rate will never be less than N/A% per annum.

                If my loan were for $ N/A at N/A % for N/A months, and the rate increased 1% at the end of N/A months, my regular

Attn: Ms. Joanne Gruber

       Re:    NationsBank Financing

Dear Madam or Sir:

1.     The purpose of this letter is to provide for the agreement among Perot
       Systems Corporation ("PSC"), NationsBank of Texas, N.A. ("NationsBank")
       and Donald D. Drobny ("Associate") with respect to the loan from
       NationsBank.

2.     Each of the parties recognizes that Associate is obtaining funding from
       NationsBank in the original principal amount of $350,000.00 (the "NB
       Principal") pursuant to a promissory note, dated as of August 26, 1996,
       by Associate payable to the order of NationsBank (the "NB Promissory
       Note"), secured by a security agreement of even date with the NB
       Promissory Note (the "NB Security Agreement").  Each of the parties
       recognizes that PSC is not loaning Associate any funds.

3.     Each of the parties hereby agrees that if PSC repurchases any Shares
       from Associate pursuant to the Stock Agreement, that it will send the
       entire balance of the repayment directly to NationsBank, regardless of
       the size of that amount (and even if in excess of the NationsBank
       Principal), unless and until it receives a signed authorization from
       Associate and NationsBank instructing it to send any additional funds
       directly to Associate.

4.     If, by the later of June 30, 1998 or the date of the maturity of the NB
       Promissory Note, PSC has not completed an initial public offering (the
       "IPO") whereby the Common Stock (or any successor security) is listed on
       a registered national securities exchange or approved for quotation in
       the National Association of Securities Dealers Automated Quotation
       System, then PSC will, within thirty days of NationsBank's written
       request, purchase the outstanding NB Promissory Note from NationsBank,
       for the then outstanding principal (which shall never exceed the
       original NB Principal) plus accrued but unpaid interest thereunder.  In
       connection with such sale, NationsBank will endorse without recourse the
       NB Promissory Note to the order of PSC, transfer to PSC good title to
       the NB Security Agreement, under which the Shares shall be pledged,
       deliver any and all Shares in its possession owned by Associate, along
       with any signed stock powers thereto, and which Shares shall be free and
       clear of additional liens and encumbrances created by, through, or under
       NationsBank other than the NB Security Agreement, which shall be
       assigned to PSC.

5.     If the Associate sells a portion of the Shares as part of the IPO or
       thereafter (with NationsBank's and PSC's consent, if needed), then
       Associate agrees to use the sale proceeds (after estimated income tax)
       to prepay the NB Promissory Note in the same manner as provided in the
       third paragraph of this letter until principal and interest under the
       Note have been paid in full.

6.     If the IPO occurs before the maturity of the NB Promissory Note but the
       Associate wishes to retain ownership of all Shares of publicly traded
       stock, the Associate will agree to collateralize the NB Promissory Note
       with such PSC vested Shares or other acceptable marketable securities
       that have a market value equal to or exceeding 150% of the loan balance
       outstanding under the NB Promissory Note, and NationsBank and the
       Associate will execute a NationsBank collateral maintenance agreement
       that will control the continuing need for shares pledged as collateral
       and any adjustments thereto.

7.     The parties agree that Associate will execute the NB Security Agreement.
       Associate agrees to execute a stock power in blank for each certificate
       evidencing any of the Shares and to deliver all such certificates with
       stock powers to PSC or NationsBank as appropriate (after the IPO,
       NationsBank will hold the certificates representing vested Shares to the
       extent needed under Paragraph 6).  Notwithstanding anything in the NB
       Security Agreement to the contrary, the parties agree that NationsBank
       will have a security interest in the Shares and whichever of PSC or
       NationsBank holds such Shares shall hold the Shares for the benefit of
       NationsBank.

       By signature below, Associate irrevocably authorizes PSC and NationsBank
to make the payments as provided in this letter, and agrees to indemnify and
hold PSC and NationsBank harmless against any loss, damage or claim in
connection with making payments as provided above.

       For purposes of notice under this letter, the parties' addresses shall
be deemed the addresses as provided above in this letter, unless the other
parties receive written notice, at least 15 days in advance, of a new address.

       If the terms of this letter are acceptable to you, please execute your

at the then-current Interest Rate. In substantially equal monthly installments, the unpaid balance as if this Note were to be due 
and payable N/A months from its date. In such event, you will send me a new payment book specifying the new payment amount. If
payments vary, I will pay the fixed part of the Amount of Payments as set out in the Truth in Lending Disclosure on each payment
date plus all accrued and unpaid interest. If payments are equal, each payment shall be applied first to interest due and then to
the unpaid Amount Financed. In any event, I will pay the unpaid principal balance of the Promissory Note plus all accrued and unpaid
interest on the final payment due date as set out in the Truth in Lending disclosure. If the Interest Rate is tied to your Consumer
Base Rate or Other Rate, the Interest Rate shall change with each change in your Consumer Base Rate or Other Rate as of the date of
any such change without notice to me, but shall not exceed the higher of the indicated rate ceiling in effect from time to time
under Article 5069-1.04 of V.A.T.S., or any ceiling authorized by any other applicable law.

rate and may or may not at any time be the best or lowest rate charged by Bank
on any loan. Any RATE based on a fluctuating index or base rate will, unless
otherwise provided, change each time and as of the date that the index or base

determine. Borrower may not prepay this Note, in whole or in part, without the
express consent of Bank or any holder hereof. If any payment is not made in

hereof or the failure to act on the part of Bank or any indulgence shown by
Bank, from time to time and in one or more instances (without notice to or
further assent from any of Obligors) and agree(s) to no action, failure to act
or failure to exercise any right or remedy on the part of Bank shall in any way
affect or impair the obligations of any Obligors or be construed as a waiver by
Bank of, or otherwise affect, any of Bank's rights under this Note, under any
endorsement or guaranty of this Note or under any of the Security Documents; and
(iii) agree(s) to pay, on demand, all costs and expenses of collection of this
Note or of any endorsement or guaranty hereof and the enforcement of Bank's
rights with respect to, or the administration, supervision, preservation,
protection of, or realization upon, any property securing payment hereof,
including, without limitation, reasonable attorney's fees.

2.   This Note is delivered in and shall be construed under the internal laws
and Judicial decisions of the State of North Carolina, and the laws of the
United States as the same might be applicable. In any litigation in connection
with or to enforce this Note or any endorsement or guaranty of this Note or any
of the Security Documents, Obligors, and each of them, irrevocably consent(s) to
and confer(s) personal jurisdiction on the courts of the State of North Carolina
and the United States courts located within the State of North Carolina, and
expressly waive(s) any objections to the venue of the courts described on the
front of this Note, and agree(s) that service of process may be made on Obligors
by mailing a copy of the summons and complaint by registered or certified mail,
return receipt requested, to their respective addresses. Nothing contained
herein shall, however, prevent Bank from bringing any action or exercising any
rights within any other state or jurisdiction or from obtaining personal
jurisdiction by any other means available by applicable law. The term "Bank" as
used in this Note shall include Bank's successors, endorsees and assigns. The
terms "Borrower" and "Obligors" as used in this Note shall include the
respective successors, assigns, heirs and personal representatives thereto or
thereof, provided, however, that no obligations of Borrower or Obligors
hereunder can be assigned without the prior written consent of Bank.

3.   The occurrence of any one or more of the following events shall constitute
a default under this Note: (i) the failure to pay or perform any obligation,
liability or indebtedness of any of Obligors to Bank, whether under this Note or
any other agreement, note or instrument now or hereafter existing, as and when
due (whether upon demand, at maturity or by acceleration, no prior demand
therefor by Bank being necessary); (ii) the failure to pay or perform any other
obligation, liability or indebtedness of any of Obligors whether to Bank or some
other party, the security for which constitutes an encumbrance on the security
for this Note; (iii) death of any of Obligors (if an individual), or a
proceeding being filed or commenced against any of Obligors for dissolution or
liquidation, or any of Obligors voluntarily or involuntarily terminating or
dissolving or being terminated or dissolved; (iv) insolvency of, business
failure of, the appointment of a custodian, trustee, liquidator or receiver for
or for any of the property of, or an assignment for the benefit of creditors by,
or the filing of a petition under any bankruptcy, insolvency or debtor's relief
law or for any adjustment of indebtedness, composition or extension by or
against any of Obligors; (v) any attachment, lien or additional security
interest being placed upon, or any seizure or forfeiture of, any of the property
which is security for this Note; (vi) acquisition at any time or from time to
time of title to the whole or any part of the property which is security for
this Note by any person, partnership, corporation or other entity other than any
of Obligors; (vii) Bank determining that any representation or warranty made by
any of Obligors to Bank is, or was, untrue or materially misleading, (viii) any
default under the Security Documents; or (ix) Bank reasonably deeming itself
insecure for any reason.

4.   Whenever there is a default under this Note (a) the entire balance
outstanding hereunder and all other obligations of Obligors to Bank (however
acquired or evidenced) shall, at the option of Bank, become forthwith due and
payable, without presentment, notice, protest or demand of any kind for the
payment of the whole or any part hereof (all of which are expressly waived by
Obligors), and/or (b) to the extent permitted by law, the rate of interest on
the unpaid principal shall, at the option of Bank, be increased to the greater
of (i) three percent (3%) over the contract rate (as shown on the face of this
Note) or (ii) three percent (3%) over the Prime Rate of Bank (the rates of
interest set forth in paragraph 4(b)(i) and 4(b)(ii) are herein alternatively
called the "Default Rate"); and/or (c) to the extent permitted by law, a
delinquency charge ("Late Fee") may be imposed in an amount not to exceed four
percent (4%) of the unpaid portion of any payment in default for more than
fifteen days in the event interest is payable in arrears or for more than thirty
days in the event interest is payable in advance. Unless the terms of this Note
call for repayment of the entire balance of this Note (both principal and
interest) in a single payment and not for installments of interest or principal
and interest, the four percent (4%) Late Fee may be imposed not only with
respect to regular installments of principal, interest, or interest and
principal, but also with respect to any other payment in default under this Note
(other than a previous Late Fee), including, without limitation, a single
payment of principal due at maturity of this Note. In the event any installment,
or portion thereof, is not paid in a timely fashion, subsequent payments will be
applied first to the past due balance (which shall not include any previous Late
Fees), specifically to the oldest maturing installment, and a separate Late Fee
will be imposed for each payment that becomes due until the default is cured.
The provisions herein for a Default Rate and /or a Late Fee shall not be deemed
to extend the time for any payment hereunder or to constitute a "grace period"
giving Obligors a right to cure any default. If the Default Rate is a factor of
the Prime Rate, the Default Rate will change each time and as of the date that
the Prime Rate of Bank changes. At Bank's option, any accrued and unpaid
interest, fees or charges may, for purposes of computing and accruing interest
on a daily basis after the due date of this Note or any payment hereunder, be
deemed to be a part of the principal balance under this Note, and interest shall
accrue on a daily compounded basis after such date at the rate provided in this
Note until the entire outstanding balance of principal and interest is paid in
full. Failure at any time to exercise any of the aforesaid options or any other
rights of Bank shall not constitute a waiver thereof, nor shall it be a bar to
the exercise of any of the aforesaid options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. If this Note is payable on
demand, the acceptance by Bank of any partial payment from any of Obligors shall
not affect the demand tenor of this Note. Bank is hereby authorized at any time
to charge against any deposit accounts of any party to this Note, as well as any
other property of such party at or under the control of Bank, without notice,
any and all obligations of such party, whether due or not.

5.   In the event any one or more of the provisions of this Note shall for any
reason be held to be invalid, illegal or unenforceable, in whole or in part or
in any respect, or in the event any one or more of the provisions of this Note
operate or would prospectively operate to invalidate this Note, then and in any
of the events, such provision or provisions only shall be deemed null and void
and shall not affect any other provision of this Note and the remaining
provisions of this Note shall remain operative and in full force and effect and
shall in no way be affected, prejudiced or disturbed thereby.

ENDORSEMENTS:

The undersigned endorser(s) hereby unconditionally undertake and agree to pay
this Note in accordance with its terms and all other obligations of Borrower 
to Bank.

             $40,000,000 DEMAND PROMISSORY NOTE DATED JULY 31, 1996
                          OF PEROT SYSTEMS CORPORATION
                                  IN FAVOR OF
                               NATIONSBANK, N.A.

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

        LOAN

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

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

        RATE

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

        Capital Adequacy.  If the Bank has reasonably determined, after the
date hereof, that the adoption or the becoming effective of, or any change in,
or any change by any Governmental Authority, central bank or comparable agency
charged with the interpretation or administration thereof in the interpretation
or administration of, any applicable law, rule or regulation regarding capital
adequacy, in each case after the date hereof, or compliance by the Bank with any
request or directive regarding capital adequacy (whether or not having the
force of law) of any such authority, central bank or comparable agency, after 
the date hereof, has or would have the effect of reducing the rate of return on
the Bank's capital or assets as a consequence of its commitments or obligations
hereunder to a level below that which the Bank could have achieved but for such
adoption, effectiveness, change or

                            $40,000,000 Demand Note
                           Perot Systems Corporation
                              dated July 31, 1996

compliance (taking into consideration the Bank's policies with respect to
capital adequacy), then, upon notice from the Bank to the Borrower, the
Borrower shall be obligated to pay to the Bank such additional amount or
amounts as will compensate the Bank for such reduction. Each determination by
the Bank of amounts owing under this paragraph shall, absent manifest error, be
conclusive and binding on the parties hereto. The Bank shall not be entitled to
any payments or compensation under this paragraph for any period of time more
than 90 days prior to the date of any request by the Bank for compensation
under this paragraph.

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

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

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

                (a)     shall subject the Bank to any tax of any kind
        whatsoever with respect to any Eurodollar Loans made by it or its
        obligation to make Eurodollar Loans, or change the basis of taxation of
        payments to the Bank in respect thereof (except for Non-Excluded Taxes
        covered by the paragraph entitled "Taxes" (including Non-Excluded Taxes

        under the paragraph entitled "Taxes") and changes in taxes measured by
        or imposed upon the overall net income, or franchise tax (imposed in
        lieu of such net income tax), of the Bank or its applicable lending
        office, branch, or any affiliate thereof);

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

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


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

        Taxes.  Except as provided below in this subsection, all payments made
by the Borrower under this Note shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future income,
stamp or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any court, or governmental body, agency or other official, excluding taxes
measured by or imposed upon the overall net income of the Bank or its
applicable lending office, or any branch or affiliate thereof, and all
franchise taxes, branch taxes, taxes on doing business or taxes on the overall
capital or net worth of the Bank or its applicable lending office, or any
branch or affiliate thereof, in each case imposed in lieu of net income taxes,
imposed: (i) by the jurisdiction under the laws of which the Bank, applicable
lending office, branch or affiliate is organized or is located, or in which its
principal executive office is located, or any nation within which such
jurisdiction is located or any political subdivision thereof; or (ii) by reason
or any connection between the jurisdiction imposing such tax and the Bank,
applicable lending office, branch or affiliate other than a connection

arising solely from the Bank having executed, delivered or performed its
obligations, or received payment under or enforced, this Note. If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to the Bank hereunder or under any Notes, (A) the amounts so payable to
the Bank shall be increased to the extent necessary to yield to the Bank (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Note, and (B) as
promptly as possible thereafter the Borrower shall send to the Bank for its own
account a certified copy of an original official receipt received by the
Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded
Taxes when due to the appropriate taxing authority or fails to remit to the Bank
the required receipts or other required documentary evidence, the Borrower shall
indemnify the Bank for any incremental taxes, interest or penalties that may
become payable by the Bank as a result of any such failure. The agreements in
this subsection shall survive the termination of this Note and the payment of
the Loans and all other amounts payable hereunder. The Bank shall not be
entitled to payment or compensation under this paragraph unless demand is made
hereunder within 90 days of the Bank having actual knowledge of facts or
circumstances entitling the Bank to compensation under this paragraph.

        Indemnity.      The Borrower promises to indemnify the Bank and to hold
the Bank harmless from any loss or expense which the Bank may sustain or incur
(other than through the Bank's gross negligence or willful misconduct) as a
consequence of (a) default by the Borrower in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Note, (b) default
by the Borrower in making any prepayment of a Eurodollar Loan with respect
to which the Borrower has given a notice in accordance with the provisions of
this Note or (c) the making of a prepayment of Eurodollar Loans on a day which
is not the last day of an Interest Period with respect thereto. With respect to
Eurodollar Loans, such indemnification may include an amount equal to the
excess, if any, of (i) the amount of interest which would have accrued on the
amount so prepaid, or not so borrowed, converted or continued, for the period
from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of the applicable Interest Period (or, in the case of a
failure to borrow, convert or continue, the Interest period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Eurodollar Loans provided for herein (excluding, however, the
Applicable Percentage included therein, if any) over (ii) the amount of
interest (as reasonably determined by the Bank) which would have accrued to the
Bank on such amount by placing such amount on deposit for a comparable period
with leading banks in the interbank Eurodollar market. The covenants of the
Borrower set forth in this paragraph shall survive the termination of this Note
and the payment of the Loans hereunder and all other amounts payable hereunder.

        CLOSING FEE

        The Borrower will pay a non-refundable fee of $20,000 to the Bank on
the date hereof in connection herewith.

        FACILITY FEE

        The Borrower agrees to pay a facility fee to the Bank in an amount
equal to one-fourth of one percent (1/4%) per annum on the average daily unused
portion of the maximum amount available under this Note. This fee shall be

              2.3 Exercise Price.  For the purpose of this Agreement, "Exercise
Price" shall mean the price per share of Class B Stock (subject to adjustment
as provided in Section 2.5) set forth below with respect to the Exercisable
Option Shares indicated:

              (a)    $7.30 per share for SBC Warburg Option Shares, subject to
Section 2.6 (the "SBC Warburg Exercise Price"); and

              (b)    The dollar amount per share for SBC Domestic Option Shares
equal to the Designated Value per share as of the date of the SBC Domestic
Event (the "SBC Domestic Exercise Price").

              2.4 Payment for and Delivery of Shares.  At the time of any
purchase of Class B Shares pursuant to the exercise of any Options, (a) SBC
shall pay the aggregate Exercise Price for the Class B Shares to be purchased
in immediately available funds by wire transfer to a bank account designated by
PSC in writing at least two (2) Business Days prior to such purchase and (b)
PSC shall deliver to SBC one (1) or more certificates, as requested by SBC,
representing the Class B Shares so purchased, registered in the name of SBC,
the SBC Affiliate or another SBC designee

reasonably acceptable to PSC.

              2.5 Adjustment to Exercise Price and Shares.  (a)  In the event
that PSC, at any time after the date hereof, declares a dividend on PSC Shares
payable in Ownership Restriction Shares, subdivides the outstanding Ownership
Restriction Shares, combines the outstanding Ownership Restriction Shares into
a smaller number of Ownership Restriction Shares, or issues any shares of its
capital stock in a reclassification of the PSC Shares (including, without
limitation, any such reclassification in connection with a consolidation or
merger involving PSC), the Exercise Price set forth in Section 2.3 and the
number of Class B Shares issuable upon the exercise of the Options will be
proportionately adjusted so that SBC will be entitled to receive, upon payment
of the aggregate Exercise Price, the aggregate number of Class B Shares that,
if such Options had been exercised immediately prior to the record date for
such dividend or the effective date of such subdivision, combination or
reclassification and at a time when the transfer books of PSC were open, SBC
would have owned upon such exercise and been entitled to receive by virtue of
such dividend, subdivision, combination, or reclassification.

              2.6 Additional Options.  If and to the extent that any Designated
Employee Options are canceled or expire, or any unvested PSC Shares received by
employees upon exercise of the Designated Employee Options are repurchased or
redeemed by or returned to PSC by such employees pursuant to pre-existing
contractual rights and are not reissued to former employees of SBC or made
subject to Designated Employee Options within three (3) years of such
repurchase, return or redemption (including all shares as to which Designated
Employee Options have been cancelled or expired, the "Reacquired Employee
Stock"), then (a) the number of Class B Shares constituting SBC Warburg Option
Shares shall be increased by the number of shares of Reacquired Employee Stock
(the "Additional Option Shares") and such Additional Option Shares will be
included as SBC Option Warburg Shares under the definition of SBC Warburg
Option Shares and will vest on a pro rata basis over the then remaining term of
the vesting schedule set forth in clause (b)(X) of the definition of SBC
Warburg Vested Shares; (b) SBC shall, as part of the SBC Warburg Option
Purchase Price, pay to PSC an amount per share equal to the Designated Value of
the Options covering the Additional OptionShares as of the date that such
shares become Additional Option Shares; (c) the Exercise Price for the
Additional Option Shares shall be an amount equal to the Designated Value per
share for the SBC Warburg Option Shares as of the date that such shares become
Additional Option Shares; and (d) SBC shall be entitled to exercise  Options to
purchase such Additional Option Shares in accordance with the procedures set
forth in Sections 2.2(a) and 2.4 with respect to the SBC Warburg Option Shares.

              2.7  Ownership Restrictions; Termination of Options.  (a) After
giving effect to any exercise of the Options by SBC and the payment of the
Exercise Prices therefor, the acquisition of Class B Shares pursuant to the
terms of this Agreement and
<PAGE>   11
                                                                         Page 11

the payment of the SBC Warburg Purchase Price and the SBC Domestic Purchase
Price, and/or any acquisition of the Options under this Agreement and the
payment of the SBC Warburg Option Purchase Price or the SBC Domestic Option
Purchase Price (collectively, the "Stock Acquisition Transactions"), (i) the
aggregate number of Class B Shares owned by SBC (including any Class B Shares
then owned by any employee of SBC), together with the aggregate number of any
Class B Shares owned by SBC at any time prior to the time of such exercise,
shall not exceed 10.0% of the aggregate number of Ownership Restriction Shares
outstanding at the time of such exercise or acquisition, and (ii) the aggregate
amounts paid by SBC in all Stock Acquisition Transactions shall not exceed 10%
of the consolidated stockholders' equity of PSC determined in accordance with
GAAP (the "Ownership Restrictions").  If any change in the BHCA makes
permissible an increase in the level of ownership by SBC or if the Federal
Reserve Board determines in advance that an increase in ownership level by SBC
is permissible under Federal Reserve Board interpretations prevailing at the
time, the Ownership Restrictions will be changed to incorporate such change in
the BHCA or such determination.

              The Options shall expire and become null and void as to each
Class B Share in respect of which the Options are not exercised within five (5)
years after the date that such Shares becomes Vested Stock; provided that such
periods shall be tolled during any time that the Ownership Restrictions prevent
the exercise of such Options.

              2.8    Outstanding Shares Deficiency.  If, on the eighth,
eleventh, fourteenth or seventeenth anniversary of the date of the Original
Agreement Date (each, a "Trigger Date"), the number of Class B Shares for which
the Options are then exercisable is limited by Section 2.7(a) because of an
insufficient number of Ownership Restriction Shares being outstanding (an
"Outstanding Shares Deficiency") and such Outstanding Shares Deficiency is not
the result of a change in the BHCA or prevailing Federal Reserve Board policies
or interpretations related to the BHCA occurring after the date hereof that
makes the Ownership Restrictions more restrictive than those described in
Section 2.7(a), then if SBC has Sold to non-affiliates all the Vested Stock
that is  available to it for Sale under the Ownership Restrictions, SBC will
have the right, exercisable in its discretion by written notice to PSC (the
"Triggering Notice") delivered within thirty (30) days after the Triggering
Date on which an Outstanding Shares Deficiency is in effect, to initiate the
procedure described below in this Section 2.8.

       Beginning upon the date of delivery of the Triggering Notice, PSC and
SBC will use all reasonable efforts to eliminate the Outstanding Shares
Deficiency, including by PSC's issuing additional Ownership Restriction Shares
and SBC's requesting that the Federal Reserve Board approve an increase in the
percentage of outstanding Ownership Restriction Shares that SBC may own.

       If the efforts required by paragraph (a) above are not successful in
eliminating
<PAGE>   12
                                                                         Page 12

the Outstanding Shares Deficiency within one hundred and twenty (120) days, PSC
and SBC will negotiate in good faith to reach a mutually acceptable resolution
to the Outstanding Shares Deficiency, which resolution shall be evidenced by a
written agreement between PSC and SBC.

       If the negotiations contemplated by paragraph (b) above do not result in
a mutually acceptable resolution of the Outstanding Shares Deficiency within
ninety (90) days (the "Negotiation Period"), PSC shall, within three (3) years
of the Trigger Date, either:

              issue additional Ownership Restriction Shares so that the number
of shares subject to the Outstanding Shares Deficiency as of the Trigger Date,
calculated  consistent with the exercise and vesting schedules set forth in
this Agreement (the number of the reduced Outstanding Shares Deficiency, the
"Adjusted Deficiency Shares"), is eliminated; or

              to the extent that PSC does not issue enough additional Ownership
Restriction Shares so that the number of Adjusted Deficiency Shares is
eliminated, then PSC will purchase from SBC, and SBC will sell to PSC, the
remaining Adjusted Deficiency Shares not so eliminated (the "Remaining Adjusted
Deficiency Shares") at the Fair Market Value (as defined below) for Class A
Shares calculated on the tenth Trading Day immediately preceding the date of
payment, or if the Class A Shares are not then regularly traded, on the date
twenty days after the determination of Fair Market Value.  The Fair Market
Value shall be the average of the Closing Price on the thirty (30) consecutive
Trading Days immediately preceding the date of calculation, or, if such
securities are not regularly traded in the securities markets, the Fair Market
Value of such securities as determined as set forth below.  If SBC and PSC fail
to agree in good faith on the Fair Market Value within five (5) days prior to
the payment date, then the Fair Market Value will be determined by an
independent appraiser mutually acceptable to SBC and PSC (the "Appraiser")
whose appraisal will be conclusive and binding on all parties.  For purposes of
such appraisal, fair market value will be calculated without premium for
control or discount for minority interests, illiquidity, or restrictions on
transfer.  The costs of the Appraiser will be borne by SBC and PSC equally.
SBC will transfer valid title to the Remaining Adjusted Deficiency Shares to
PSC, free and clear of any and all Encumbrances, other than those attributable
to the legal status of PSC, and other than restrictions imposed by applicable
law (including, without limitation, federal or state securities laws).

share of $7.30 (the "SBC Warburg Purchase Price"), which will be payable in
immediately available funds to PSC on or before April 28, 1997.

              (b)  Upon a date mutually agreed by SBC and PSC not later than 15

       2A.2  Return of Shares and Cancellation of Options on Termination.

              (a)  In the event of the termination of the SBC Domestic
       Agreement for any reason, (i) all Options to purchase Unvested SBC
       Domestic Stock will be terminated and be null and void and (ii) SBC will
       deliver to PSC, or will cause to be delivered to PSC at the SBC/D
       Repurchase Closing (as defined below), against payment therefor as
       provided below, good and marketable title to all Unvested SBC Domestic
       Shares together with all dividends and other distributions made with
       respect to such Unvested SBC Domestic Shares, free and clear of any
       Encumbrances attributable to any actions taken by SBC or any of its
       Affiliates.  At the SBC/D Repurchase Closing, PSC will pay to SBC an
       amount equal to the aggregate amount of the SBC Domestic Exercise Price
       and SBC Domestic Purchase Price paid with respect to the Unvested SBC
       Domestic Shares being acquired by PSC at the SBC/D Repurchase Closing.
       The "SBC/D Repurchase Closing" will take place at the offices of PSC on
       the Business Day specified by PSC by 10 day's written notice to SBC
       provided that the SBC/D Repurchase Closing shall take place not later
       than 75 days after the termination of the SBC Domestic Agreement.
       Notwithstanding the foregoing, if the payment of the  amount provided
       above would cause PSC or any of its Affiliates to be in default under
       any material agreement or shall be prohibited by any applicable law,
       then PSC will have the right to defer the SBC/D Repurchase Closing for a
       period of not more than one year following the termination of the SBC
       Domestic Agreement.

              (b) In the event of the termination of the SBC Warburg Agreement
       for any reason, (i) all Options to purchase Unvested SBC Warburg Stock
       will be terminated and be null and void and (ii) SBC will deliver to
       PSC, or will cause to be delivered to PSC at the SBC/W Repurchase

       against payment therefor as provided below, good and marketable title to
       all Unvested SBC Warburg Shares together with all dividends and other
       distributions made with respect to such Unvested SBC Domestic Shares,
       free and clear of any Encumbrances attributable to any actions taken by

       written notice to SBC provided that the SBC/W Repurchase Closing shall
       take place not later than 75 days after the termination of the SBC
       Warburg EPI Agreement.  Notwithstanding the foregoing, if the payment of
       the amount provided above would cause PSC or any of its Affiliates to be

       applicable law, then PSC will have the right to defer the SBC/W
       Repurchase Closing for a period of not more than one year following the
       termination of the SBC Warburg EPI Agreement.

Article IIA hereof, the Class B Shares to be issued to SBC will be duly
authorized and, when issued and delivered and paid for in accordance with this
Agreement, will be validly issued, fully paid and non-assessable.  The delivery
to SBC of any Class B Shares issued pursuant to the Options, and payment

valid title thereto, free and clear of any and all Encumbrances, other than
Encumbrances arising out of actions taken by SBC or attributable to the legal
status of SBC, and other than restrictions imposed by applicable law
(including, without limitation, federal or state securities laws) and this

were outstanding.

                                   ARTICLE IV

                            RESTRICTIONS ON TRANSFER

              4.1  No Market Disruption.  SBC shall not at any time Sell any
Class B Shares in any manner that would, based on the advice of an
internationally recognized investment banking firm reasonably acceptable to
both parties hereto, disrupt the orderly development of a public market for the
PSC Shares, provided that this Section shall not be applied to limit the
ability of SBC to Sell up to 200,000 Class B Shares to employees of SBC or its
Affiliates, and/or to Sell Class B Shares as permitted by Rule 144 (or any
successor thereto) under the Securities Act.

              4.2   Transfer of Options; Initial Public Offering.  (a)  Neither
the Unvested Stock, the Options nor any interest in the Unvested Stock or the
Options will be transferable to any Person.  SBC shall not Sell any Class B
Shares until the first anniversary of the IPO Closing Date, provided that SBC
(i) may sell up to 200,000 Class B Shares to employees of SBC or its Affiliates
and (ii) may, with the prior written consent of the investment banking firm
acting as managing underwriter in connection with the Initial Public Offering
and in accordance with the procedure specified in Section 4.2(b), Sell up to
the lesser of (x) that number of Class B Shares owned by SBC which represents
ten percent (10%) of the aggregate number of Ownership Restriction Shares
offered in the Initial Public Offering or (y) 300,000 Class B Shares, subject
to adjustment in a manner consistent with Section 2.5.

                     (b)    PSC agrees that, in the event it intends to launch
the Initial Public Offering, it shall promptly give written notice (the "IPO
Notice") to SBC as soon as practicable prior to the date that the registration
statement with respect to the proposed Initial Public Offering is filed with
the Commission, but in no event less than fifteen (15) days prior to such
filing.  SBC shall have the right, exercisable upon written notice to PSC
within five (5) Business Days after receipt of the IPO Notice, to have PSC
include in such registration the number of Ownership Restriction Shares owned
by SBC which are to be Sold in the Initial Public Offering in compliance with
the provisions of Section 4.2(a).

                     (c)    It shall be a condition precedent to the obligation
of PSC to take any action pursuant to this Section 4.2 in respect of the
Ownership Restriction Shares that are to be registered at the request of SBC
that (i) SBC furnish to PSC such information regarding the Ownership
Restrictions Shares held by SBC as may be required pursuant to the Securities
Act and the rules and regulations of the Commission promulgated thereunder or
otherwise reasonably requested by the managing underwriter of an underwritten
Initial Public Offering, and (ii) SBC enter into an underwriting agreement with
any underwriter of an underwritten Initial Public Offering
<PAGE>   16
                                                                         Page 16

containing representations, warranties, covenants, conditions, and indemnities
(for the benefit of PSC, its officers and directors, any Person who "controls"
PSC within the meaning of the Securities Act and such underwriters), with
respect to information provided by SBC specifically for inclusion in the
registration statement relating to the Initial Public Offering, that are
reasonably satisfactory to the underwriters and customary for transactions of
the type contemplated.  Except as provided in the following sentence, PSC will
bear all expenses arising or incurred in connection with any of the
transactions contemplated by this Section 4.2,  such expenses to include,
without limitation, (i) all expenses incident to filing with the National
Association of Securities Dealers, Inc.; (ii) registration fees and other
expenses incurred in connection with registering the Ownership Restriction
Shares under the Securities Act; (iii) all expenses incident to listing the PSC
Shares on any stock exchange; (iv) printing expenses; (v) legal fees and
expenses of PSC; (vi) accounting fees and expenses, including the fees and
expenses incurred in connection with any special audits or comfort letters
incident to or required by any such registration or qualification; (vii) the
fees and expenses of any transfer agent; and (viii) the expenses of complying
with the securities or blue sky laws of any jurisdictions in connection with
such registration or qualification.  Notwithstanding the foregoing, SBC will be
responsible for the payment of any fees and expenses relating to the
registration of any Ownership Restriction Shares to be sold by it (including,
without limitation, underwriting discounts and commissions) and for the fees
and expenses of its counsel.

              4.3 BHCA Requirements.  SBC shall not, at any time, Sell any
Class B Shares or any interest therein in any manner that would contravene the
requirements of the BHCA and any rules and regulations or interpretations
promulgated or issued by the Federal Reserve Board pursuant thereto.

              4.4 First Offer.  (a)  SBC acknowledges and agrees that, in the
event it shall, at any time during the period beginning on the Adjustment Date
and ending on the date of termination of the SBC Warburg EPI Agreement, desire,
other than in connection with the Initial Public Offering, to Sell Class B
Shares acquired pursuant to this Agreement, SBC shall first offer to sell any
such Class B Shares or Options in respect thereof to PSC for a price, including
an amount equal to the fair market value of any consideration not paid in cash,
and upon terms, specified in writing by SBC and delivered to PSC (each such
offer, a "First Offer"), provided that SBC shall not be required to deliver a
First Offer to PSC in respect of Class B Shares being Sold by SBC in any
widely-disbursed offering or in any transaction that complies with Rule 144 (or
any successor thereto) under the Securities Act, or in respect of up to 200,000
Class B Shares which may be Sold to employees of SBC or its Affiliates.

                     (b)    In the event that PSC notifies SBC in writing of
its acceptance of any First Offer within twenty (20) days of receipt by PSC of
the First Offer, SBC shall be obligated to Sell, and PSC shall be obligated to
purchase, the Class B Shares or Options in respect thereof at the price,
including an amount equal to the
<PAGE>   17
                                                                         Page 17

fair market value of any consideration not paid in cash, and upon the terms
contained in such First Offer.  The notice of acceptance by PSC shall specify a
date for the closing of the purchase, which shall be not more than twenty (20)
days after the date of such notice.  At such closing, PSC will deliver the
purchase price specified in Section 4.4(a) to SBC in immediately available
funds against receipt by PSC from SBC of one (1) or more certificates
representing the Class B Shares described herein or the cancellation of Options
in respect thereof, which Class B Shares or Options in respect thereof shall be
free of any Encumbrances attributable to any action taken by SBC or any of its
Affiliates.

                (c)  In the event PSC rejects or does not accept a First Offer
within twenty (20) days of its receipt, SBC shall be entitled to offer the
Class B Shares referred to in the First Offer to third parties for a price and
upon other terms and conditions at least as favorable to SBC as those set forth
in the First Offer.

                (d)  If any third party shall accept an offer by SBC's
complying with the requirements of Section 4.4(c), then PSC's right to purchase
or otherwise acquire the Class B Shares subject to such offer or Options in
respect thereof shall be terminated; provided that in the event such acceptance
does not result in a sale or acquisition of such Class B Shares within three
(3) months of the rejection or non-acceptance of the First Offer by PSC, then
SBC shall not Sell such Class B Shares to any third party unless such Shares or
Options in respect thereof are offered again to PSC as provided in Section
4.4(a).

                (e)  The rights set forth in this Section 4.4 shall not be
assignable by PSC except in whole and to a Wholly-Owned Subsidiary of PSC.

of such press release or public disclosure, which consent shall not be
unreasonably withheld.

              5.4 Initial Public Offering.  (a)  PSC and SBC each acknowledges
and agrees that it is the intention of PSC to commence an Initial Public
Offering in respect of the PSC Shares, and to make application for the listing

PSC Shares on NASDAQ-National Market, within twenty-four (24) months of the
Adjustment Date.

                (b)    SBC acknowledges and agrees that it will reasonably
cooperate with the efforts of PSC to consummate the Initial Public Offering.

              5.5 Acquisition of PSC Shares.  SBC covenants and agrees that it

              5.6 Status of Class B Shares.  (a)  PSC hereby covenants and

                                                                         Page 19

permit the conversion of Class B Shares into Class A Shares pursuant to the
provisions of Section 3 of Article IV of the Certificate of Incorporation of
PSC.

              (b)  So long as SBC owns any Class B Shares, (i) PSC shall not
issue any Class B Shares to any Person other than SBC and (ii) PSC shall treat

                                   ARTICLE VI

                           SURVIVAL OF COVENANTS AND
                        REPRESENTATIONS; INDEMNIFICATION

              6.1 Survival of Covenants and Representations.  The respective
covenants and agreements of the parties hereto contained in this Agreement
shall survive the consummation of the transactions contemplated by this
Agreement and the other Transaction Documents.  The representations and
warranties in Section 3.1 shall survive indefinitely, and SBC shall be entitled
to institute a claim in respect of such representation and warranty at any
time.  The representations and warranties of PSC set forth in Section 3.2 shall
not survive the date of execution of this Agreement.

              6.2 Indemnification by PSC.  PSC shall indemnify, defend and hold
SBC harmless from and against any and all direct, out-of-pocket, pecuniary
damage, loss, cost (including reasonable attorneys' fees and expenses) and
expense (collectively, "Loss and Expense") actually incurred that results from
the failure of any representation or warranty made in Section 3.1 by PSC to be
true and correct in all material respects as of the date hereof.

              6.3 [Intentionally Omitted.]

              6.4 Indemnification Procedure.  (a)  Within a reasonable time
after the incurrence of any Loss and Expense by the party seeking
indemnification (the "Indemnified Party"), including, without limitation, any
claim by a third party described in Section 6.4(c), that might give rise to
indemnification hereunder, the Indemnified Party shall deliver to the party
from which indemnification is sought (the "Indemnifying Party") a certificate
(the "Certificate"), which Certificate shall:

              (1)    state that the Indemnified Party has paid or properly
       accrued Loss and Expense, or anticipates that it will incur liability
       for Loss and Expense for which such Indemnified Party is entitled to
       indemnification pursuant to this Agreement; and
<PAGE>   20
                                                                         Page 20

              (2)    specify in reasonable detail each individual item of Loss
       and Expense included in the amount so stated, the date such item was
       paid or properly accrued, the basis for any anticipated liability and
       the nature of the misrepresentation, breach of warranty or claim to
       which each such item is related and the computation of the amount to
       which such Indemnified Party claims to be entitled hereunder.

              Failure of an Indemnified Party to deliver a Certificate as
provided in this Section 6.4(a) shall not affect such Indemnified Party's right
to indemnification hereunder unless and to the extent that such failure
actually prejudices the Indemnifying Party.

              (b)  In case the Indemnifying Party shall object to the
indemnification of an Indemnified Party in respect of any claim or claims
specified in any Certificate, the Indemnifying Party shall, within thirty (30)
calendar days after receipt by the Indemnifying Party of such Certificate,
deliver to the Indemnified Party a written notice to such effect and the
Indemnifying Party and the Indemnified Party shall, within the thirty (30)
calendar day period beginning on the date of receipt by the Indemnified Party
of such written objection, attempt in good faith to agree upon the rights of
the respective parties with respect to each of such claims to which the
Indemnifying Party shall have so objected.  If the Indemnified Party and the
Indemnifying Party shall succeed in reaching agreement on their respective
rights with respect to any of such claims, the Indemnified Party and the
Indemnifying Party shall promptly prepare and sign a memorandum setting forth
such agreement.  Should the Indemnified Party and the Indemnifying Party be
unable to agree as to any particular item or items or amount or amounts, then
the Indemnified Party and the Indemnifying Party shall submit such dispute to a
court of competent jurisdiction.

              (c)  Promptly after the assertion by any third party of any claim
against any Indemnified Party that, in the judgment of such Indemnified Party,
may result in the incurrence by such Indemnified Party of Loss and Expense for
which such Indemnified Party would be entitled to indemnification pursuant to
this Agreement, such Indemnified Party shall deliver to the Indemnifying Party
a written notice describing in reasonable detail such claim and such
Indemnifying Party may, at its option, assume the defense of the Indemnified
Party against such claim (including the employment of counsel, who shall be
reasonably satisfactory to such Indemnified Party, and the payment of
expenses).  Any Indemnified Party shall have the right to employ separate
counsel in any such action or claim and to participate in the defense thereof,
but the fees and expenses of such counsel shall not be at the expense of the
Indemnifying Party unless (i) the Indemnifying Party shall have failed, within
a reasonable time after having been notified by the Indemnified Party of the
existence of such claim as provided in the preceding sentence, to assume the
defense of such claim, (ii) the employment of such counsel has been
specifically authorized in writing by the Indemnifying Party, which
authorization shall not be unreasonably withheld, or (iii) the named parties to
any such
<PAGE>   21
                                                                         Page 21

action (including any impleaded parties) include both such Indemnified Party
and the Indemnifying Party and such Indemnified Party shall have been advised
in writing by such counsel that there exists a conflict of interest between the
Indemnifying Party and the Indemnified Party.  No Indemnifying Party shall be
liable to indemnify any Indemnified Party for any settlement of any such action
or claim effected without the consent of the Indemnifying Party but if settled
with the written consent of the Indemnifying Party, or if there be a final
judgment for the plaintiff in any such action, the Indemnifying Party shall
indemnify and hold harmless each Indemnified Party from and against any loss or
liability by reason of such settlement or judgment.

              (d)    Claims for Loss and Expense specified in any Certificate
to which an Indemnifying Party shall not object in writing within thirty (30)
calendar days of receipt of such Certificate, claims for Loss and Expense
covered by a memorandum of agreement of the nature described in Section 6.4(b),
claims for Loss and Expense the validity and amount of which shall have been
the subject of judicial determination as described in Section 6.4(b) and claims
for Loss and Expense the validity and amount of which shall have been the
subject of a final judicial determination as described in Section 6.4(c) are
hereinafter referred to, collectively, as "Agreed Claims."  Within ten (10)
Business Days of the determination of the amount of any Agreed Claim, the
Indemnifying Party shall pay to the Indemnified Party an amount equal to the
Agreed Claim by wire transfer of immediately available funds to the bank
account or accounts designated in writing by the Indemnified Party not less
than two (2) Business Days prior to such payment.

              6.5 Exclusive Remedy.  The sole and exclusive remedy of SBC for
breach of the representations and warranties set forth in Section 3.1, except
as specified in the last sentence of this Section 6.5, shall be restricted to
the indemnification rights set forth in this Article VI.  The parties expressly
agree that no Person will be liable for any consequential, punitive, exemplary
or special damages.  Notwithstanding the foregoing, this Section 6.5 shall not
be applied to limit the liability of either party for the actual fraud of such
party.

the benefits

thereof only by a written instrument signed by the party granting such waiver,
but such waiver or failure to insist upon strict compliance with such
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

permitted hereunder shall be in writing and shall be deemed given if delivered

successors and permitted assigns any rights, remedies, obligations or

assign its rights and obligations under this Agreement to the SBC Affiliate,
provided that no such assignment shall relieve SBC of liability in the event of

forth herein, and provided further that in the event that, and prior to such
time as, the SBC Affiliate ceases to be a Wholly-Owned Subsidiary of SBC, SBC
shall take all action necessary to ensure that any Options or shares purchased
hereunder, any securities purchased upon any exercise of the Options and any
rights or obligations held by the SBC Affiliate hereunder are transferred to
SBC or a Wholly-Owned Subsidiary of SBC.

              7.5  GOVERNING LAW.  THE INTERPRETATION AND CONSTRUCTION OF THIS
AGREEMENT, AND ALL MATTERS RELATING HERETO, SHALL BE GOVERNED BY THE LAW OF THE
STATE OF NEW YORK, OTHER THAN THE CONFLICTS-OF-LAW PRINCIPLES THEREOF, PROVIDED
THAT THE LAWS OF THE RESPECTIVE JURISDICTION OF INCORPORATION OF THE PARTIES
WILL GOVERN THE INTERNAL AFFAIRS OF SUCH PARTIES.

              7.6  Jurisdiction; Agent for Service of Process.  Any judicial
proceeding brought against any of the parties to this Agreement or any dispute
under or arising out of or in connection with this Agreement or any matter
related hereto may be brought in the courts of the State of New York or in the
United States District Court for the Southern District of New York, and, by
execution and delivery of this Agreement, each of the parties to this Agreement
accepts the exclusive jurisdiction of such courts, and irrevocably agrees to be
bound by any judgment rendered thereby in connection with this Agreement.  PSC

more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one (1) and the same instrument.

              7.8  Headings.  The Article and Section headings contained in
this Agreement are solely for the purpose of reference, are not part of the
agreement of the parties and shall not in any way affect the meaning or
interpretation of this Agreement.

              7.9  Severability.  If any provision of this Agreement is
determined to be invalid, illegal or incapable of being enforced by any rule of
law or public policy, all other provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner adverse to
either party.  Upon such determination that any provision is invalid, illegal
or incapable of being enforced, the parties hereto shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the

                         AGREEMENT, TERM AND AUTHORITY

2.1      Scope of Agreement.  Except as the Contracting Parties may otherwise
         expressly agree in an EPI Agreement, this Agreement establishes the
         standard terms and conditions that will be applicable to each EPI
         Agreement.

2.2      Term.  The term of this Agreement will commence on the Adjustment
         Date, and will continue until terminated by the mutual agreement of
         PSC Parent and SBC Parent or pursuant to Sections 8.1 through 8.9 or
         10.7(a) hereof; provided, however, that this Agreement may be
         terminated effective at any time on or after December 31, 2008 by
         either of the parties hereto by giving at least sixty (60) days prior
         written notice to the other party.  Notwithstanding the termination of
         this Agreement for any reason, any provisions of this Agreement that
         have been incorporated by reference into any EPI Agreement entered
         into prior to such termination will remain valid and binding
         provisions of that EPI Agreement unless the Contracting Parties
         thereto otherwise agree.

2.3      Authority.  PSC Parent represents and agrees that as of the Adjustment
         Date it has, and as of the effective date of each EPI Agreement it
         will have, the authority to cause each PSC Entity to act with respect
         to all applicable matters relating to this Agreement and any EPI
         Agreement to which that PSC Entity is a Contracting Party, including
         the giving or withholding of any approval, acceptance, consent,
         notice, or other action required or permitted by this Agreement or
         that EPI Agreement, and that it will be responsible for the
         performance of all of the obligations of the members of the PSC Group
         under each of the applicable EPI Agreements and for causing each
         member of the PSC Group to comply with all applicable provisions of
         each applicable EPI Agreement.  SBC Parent represents and agrees that
         as of the Adjustment Date it has, and as of the effective date of each
         EPI Agreement it will have, the authority to cause each SBC Entity to
         act with respect to all applicable matters relating to this Agreement
         and any EPI Agreement to which that SBC Entity is a Contracting Party,
         including the giving or withholding of any approval, acceptance,
         consent, notice, or other action required or permitted by this
         Agreement or that EPI Agreement, and that it will be responsible for
         the performance of all obligations of the members of the SBC Group
         under each EPI Agreement and for causing each member of the SBC Group
         to comply with all applicable provisions of each applicable EPI
         Agreement.

2.4      Major Changes:

         (a)     If at any time during the term of the SBC Warburg EPI
                 Agreement, and subject to the provisions of Section 8.7
                 hereof, a member or combination of members of the SBC Group
                 acquires, in a single transaction or series of related
                 transactions, any business, whether through acquisition of
                 securities, assets or otherwise that could reasonably be
                 expected to result in the revenue paid to the applicable PSC
                 Entity under the SBC Warburg EPI Agreement increasing, on an
                 annualized basis in the





                                       9
<PAGE>   10
                 year of the transfer, by more than fifty percent (50%), if
                 that business were to become a part of the SBC Warburg
                 Division, then that business will not become part of the SBC
                 Warburg Division for purposes of this Agreement or the SBC
                 Warburg EPI Agreement.

         (b)     If at any time during the term of the SBC Warburg EPI
                 Agreement, a member or combination of members of the SBC Group
                 sells or otherwise disposes outside of the SBC Group, in a
                 single transaction or series of related transactions, of any
                 portion of its or their business that could reasonably be
                 expected to result in the revenue paid to the applicable PSC
                 Entity under that EPI Agreement decreasing, on an annualized
                 basis in the year of the transfer, by more than fifty percent
                 (50%), then SBC Parent will require (unless PSC Parent waives
                 the requirement as described in the last sentence of this
                 Section 2.4(b)) the purchaser of that business to assume the
                 applicable SBC Entity's obligations under the SBC Warburg EPI
                 Agreement that relate to the transferred business from the
                 date of the transfer and to continue to obtain from the
                 applicable PSC Entity the acquired business' requirements for
                 the Services in accordance with the terms and conditions of
                 the SBC Warburg EPI Agreement.  The SBC Warburg EPI Agreement
                 will continue to apply to the business not so transferred.
                 Unless the purchaser of the transferred business has a credit
                 rating substantially equivalent to or better than, and a
                 shareholders' equity equal to or larger than, SBC Parent, the
                 PSC Group may, but will have no obligation to, provide
                 Services to the purchaser, and, if the PSC Group elects to not
                 provide Services to the purchaser, the purchaser will have no
                 obligation to assume any obligations under any EPI Agreement.

         (c)     If an event described in Section 2.4(a) or 2.4(b) shall occur,
                 the provisions of Section 4.4 of the Master Agreement shall
                 apply.


                                  ARTICLE III
                                    SERVICES

3.1      Services.  It is the intention of SBC Parent and PSC Parent that an
         EPI Agreement be entered into for any Services to be provided by any
         member of the PSC Group to any member of the SBC Group.

3.2      Scope of EPI Agreement.  Unless otherwise expressly provided in an EPI
         Agreement, each EPI Agreement will provide that the applicable PSC
         Entity will provide, and the applicable SBC Entity will obtain from
         that PSC Entity, that SBC Entity's requirements for Operational
         Management of the EPI of that SBC Entity.

3.3      Terms of EPI Agreements.  Unless the Contracting Parties to an EPI
         Agreement otherwise expressly agree in that EPI Agreement, each EPI
         Agreement may:





                                       10
<PAGE>   11
         (a)     Incorporate by reference the terms and conditions of this
                 Agreement identified for such purpose in that EPI Agreement.

         (b)     Designate the date as of which the provisions of that EPI
                 Agreement will be effective and the term or period of time
                 during which the applicable PSC Entity will provide the
                 Services pursuant to that EPI Agreement.

         (c)     Describe the obligations of the applicable PSC Entity pursuant
                 to that EPI Agreement, including the Services to be provided
                 by the PSC Entity pursuant to that EPI Agreement and any
                 Service Levels applicable to those Services.

         (d)     Describe the obligations of the applicable SBC Entity pursuant
                 to that EPI Agreement, including any obligations relating to
                 the provision of space, facilities, equipment, or other
                 support to be provided by the SBC Entity that are different
                 from, or in addition to, the resources and support to be
                 provided as described in this Agreement.

         (e)     Specify the applicable PSC Entity's charges and the method of
                 payment of those charges for the Services provided under that
                 EPI Agreement, as well as the methodology for any bonus
                 payments to the PSC Entity or credits to the SBC Entity.

         (f)     Include any other provisions deemed necessary or desirable by
                 the Contracting Parties to that EPI Agreement, including
                 provisions necessary to comply with local law or custom or
                 regulation or internal policies of the members of the SBC
                 Group.

3.4      Security Procedures.  With respect to each EPI Agreement, the
         applicable SBC Entity will be responsible for developing, maintaining
         and updating the Security Procedures, the form and substance of which
         will be determined by the applicable SBC Entity.  The applicable SBC
         Entity will be responsible for providing those Security Procedures,
         including updates and modifications, to the applicable PSC Entity.
         During the term of each EPI Agreement, the applicable PSC Entity will,
         and will cause its employees to, comply, with respect to Services
         provided to members of the SBC Group, with the Security Procedures
         with which it has been provided by the applicable SBC Entity to the
         extent that those Security Procedures are no more rigorous than
         similar security procedures applicable to the members of the SBC
         Group.  The applicable PSC Entity will provide notice to the
         applicable SBC Entity of any known instances of non-compliance with
         the Security Procedures by that PSC Entity.

3.5      Export Matters.  With respect to each EPI Agreement, the applicable
         PSC Entity will be responsible for all non-banking related export
         regulations with respect to PSC Systems, and the applicable SBC Entity
         will be responsible for all non-banking related export regulations
         with respect to SBC Systems (other than SBC Systems with respect to
         which PSC is the purchaser).

<PAGE>   12
3.6      Other Regulatory Issues.  No Contracting Party will be required to
         commit an illegal act in connection with any EPI Agreement, and if an
         EPI Agreement would require such an act, then that EPI Agreement will
         be deemed amended by modifying the provisions to the extent necessary
         to make it legal while preserving the economic benefits to each party,
         or, if that is not possible, by substituting another provision that is
         legal and enforceable and achieves the same objective.

3.7      Future EPI Agreements.  SBC Parent and PSC Parent will negotiate in
         good faith to execute an EPI Agreement, on or prior to December 31,
         1998, having a term of ten (10) years and a similar scope and size to
         the SBC Warburg EPI Agreement relating to SBC's private banking and
         retail and commercial banking activities in Switzerland (the "SBC
         Domestic Division"), which agreement will (i) include such terms and
         conditions consistent with those set forth in the SBC Warburg EPI
         Agreement as may be agreed upon by the parties thereto and (ii) state
         that it is the definitive agreement referred to in this Section 3.7 (a
         "Domestic Agreement").   SBC shall be considered to have negotiated in
         good faith as provided above if, on or before December 31, 1999, SBC
         Parent does not enter into a significant information technology
         outsourcing or similar agreement with a third party that is not an
         Affiliate of SBC Parent to provide services to the SBC Domestic
         Division, but continues to provide those services internally.. The
         obligation of the parties set forth in this Section 3.7 shall
         terminate upon termination of the SBC Warburg EPI Agreement.



                                  ARTICLE IV
                                SBC RESOURCES

4.1      SBC Systems.

         (a)     SBC Parent represents that one or more members of the SBC
                 Group has all rights in and to the SBC Systems necessary to
                 grant to the members of the PSC Group the rights described in
                 this Section 4.1.  SBC Systems will be and remain the property
                 of the members of the SBC Group.  With respect to the Licensed
                 SBC Systems required by a PSC Entity to provide the Services
                 under any EPI Agreement, including those Licensed SBC Systems
                 listed in the applicable EPI Agreement, SBC Parent hereby
                 grants to PSC Parent and the applicable PSC Entity the
                 non-exclusive right, at no charge to PSC Parent or the
                 applicable PSC Entity, to market, license, operate, copy,
                 modify or otherwise use those specified Licensed SBC Systems
                 in order to provide Services to the applicable SBC Entity
                 pursuant to that EPI Agreement, and to provide services to
                 other customers of members of the PSC Group and for the PSC
                 Group members' own internal use.  PSC Parent acknowledges and
                 agrees that for purposes of using the Licensed SBC Systems for
                 third party customers of members of the PSC Group and for the
                 PSC Group members' own internal use, the license granted
                 pursuant to this Section 4.1(a) is granted on an "AS IS"
                 basis, and each member of the PSC Group will remove all





                                       12
<PAGE>   13
                 indicia of any member of the SBC Group's interest in and
                 affiliation with the Licensed SBC System prior to using the
                 Licensed SBC System for third party customers of members of
                 the PSC Group.

         (b)     The members of the SBC Group, with the cooperation and
                 assistance of the members of the PSC Group, will use all
                 commercially reasonable efforts to obtain any consents from
                 third parties necessary for the applicable PSC Entity to
                 operate any Licensed SBC Systems as contemplated by this
                 Agreement.  Upon the termination of the applicable EPI
                 Agreement, the members of the PSC Group may continue to use
                 the Licensed SBC Systems for the internal operations of the
                 members of the PSC Group and for customers of members of the
                 PSC Group, provided that:

                 (1)      Except as otherwise necessary to utilize the Licensed
                          SBC Systems as authorized by this Agreement,  no
                          member of the PSC Group will at any time allow the
                          Licensed SBC Systems, or any of the various
                          components thereof or any modifications thereto, to
                          be disclosed to third parties, sold, assigned, leased
                          or commercially exploited in any way, with or without
                          charge, by that member of the PSC Group or its
                          employees or agents or, except to the extent required
                          for normal operation of the Licensed SBC Systems, to
                          be copied or reproduced, in whole or in part, by any
                          person, firm or corporation, at any time.

                 (2)      The members of the PSC Group agree that the Licensed
                          SBC Systems are the valuable property of one or more
                          members of the SBC Group, that violation in any
                          material respect of any provision of this Section 4.1
                          would cause the members of the SBC Group irreparable
                          injury for which they would have no adequate remedy
                          at law and, in addition to any and all other remedies
                          or rights the members of the SBC Group may have at
                          law or in equity, the members of the SBC Group will
                          be entitled to preliminary and other injunctive
                          relief against any such violation.

         (c)     During the term of this Agreement, no member of the SBC Group
                 may license the Licensed SBC Systems to any third party.
                 Notwithstanding the foregoing, however, the members of the SBC
                 Group may use the Licensed SBC Systems for their own internal
                 purposes and may provide the Licensed SBC Systems to clients
                 of members of the SBC Group as necessary in conjunction with
                 the SBC Group members' services to their clients.

         (d)     Notwithstanding the provisions of Section 4.1(a) hereof, no
                 member of the PSC Group may use the Restricted Application
                 Systems for its own internal purposes or for any of its
                 customers (other than a member of the SBC Group), unless PSC
                 Parent and SBC Parent agree that such use is in the best
                 interests of the parties and agree in writing upon a mutually
                 acceptable royalty structure.

         (e)     Except as otherwise provided in an EPI Agreement, the PSC
                 Group will operate and the SBC Group will maintain the
                 Restricted Application Systems and related documentation.  The
                 PSC Group will maintain the documentation of each Licensed SBC
                 System as long as that Licensed SBC System is being operated
                 and maintained by the PSC Group hereunder.  The PSC Group will
                 not have access to the source code for the Restricted
                 Application Systems or system documentation therefor.

4.2      Rights in Developed Systems.  Ownership and use rights in Systems and
         modifications to Systems developed on or after the Original Agreement
         Date will be as follows:

         (a)     Except as provided in Sections 4.2(b), 4.2(c), 4.2(d) and
                 4.2(e) below, the members of the PSC Group will own any
                 System, and any modifications to any System, developed on or
                 after the Original Agreement Date by the applicable PSC Entity
                 pursuant to this Agreement or any EPI Agreement, subject to
                 the SBC Group's rights in the underlying SBC System if an SBC
                 System was the basis for such modification.

         (b)     If PSC performs any software development project pursuant to
                 any EPI Agreement that is specifically requested, identified
                 in writing when requested as subject to this Section 4.2(b)
                 and agreed prior to such development by PSC and SBC to be
                 wholly financed by SBC, the copyright in the software
                 resulting from that project will be owned by SBC, and PSC will
                 be limited to using that software for SBC and PSC's internal
                 use except as provided in Section 4.2(f) below.

         (c)     Ownership of Restricted Applications Systems will remain with
                 SBC.

         (d)     Incidental infrastructure software programs developed by PSC
                 in the course of providing services pursuant to an EPI
                 Agreement will be owned by PSC unless the cost of development
                 exceeds $5,000,000 per individual program in a given Budget
                 Period (as defined in the SBC Warburg EPI Agreement), and is
                 wholly financed by SBC, in which case the copyright in such
                 program will be owned by SBC and the rights of PSC will be as
                 described in Section 4.2(b) above for a software development
                 project specifically requested and agreed by PSC and SBC to be

                 members of the SBC Group, will be owned by SBC Parent, and SBC
                 Parent will grant to members of the PSC Group the right, at no

                 use those SBC Systems on behalf of the members of the SBC
                 Group, for the internal use of the members of the PSC Group,
                 and for any other customer of any member of the PSC Group.

                 as described in Sections 4.2(b), 4.2(c) or 4.2(d) (the
                 "Developed SBC Systems") for any customer of that PSC Entity
                 (other than a member of the SBC Group), that PSC Entity will
                 obtain the consent of the applicable SBC Entity based upon a
                 business case prepared by the PSC Entity for the applicable
                 SBC Entity's review and approval specifying (i) any capital
                 investment that will be required from that SBC Entity to
                 obtain any additional resources to provide services to the
                 customer of the PSC Group and, if so, any payments that will
                 be made to the applicable SBC Entity in connection with or
                 attributable to the use of the Developed SBC Systems; (ii) any
                 impact on the overall operating expenses of the Developed SBC
                 Systems; (iii) any impact the introduction of the third party
                 customer would have on existing Service Levels; and (iv) any
                 impact on the applicable PSC Entity's charges to the
                 applicable SBC Entity for the Services.  The applicable PSC
                 Entity will also satisfy the applicable SBC Entity, in that
                 SBC Entity's sole discretion, that adequate Security
                 Procedures have been instituted to prevent disclosure of any
                 Confidential Information of the SBC Group to the third party
                 customer.

4.3      PSC Systems.  PSC Parent represents that one or more members of the
         PSC Group will have, at the time of the use of PSC Systems for
         provision of the Services, all rights in and to the PSC Systems
         necessary to use the PSC Systems that PSC elects to use on behalf of
         members of the SBC Group and to license the PSC Systems to the members
         of the SBC Group that PSC Parent is obligated to license pursuant to
         this Section 4.3.  PSC Systems will be and remain the property of PSC
         Parent, and the members of the SBC Group will have no rights or
         interests therein except as described herein.  During the term of an
         EPI Agreement, PSC Parent hereby grants to the applicable SBC Entity,
         and that SBC Entity will be deemed to accept from PSC Parent, a
         nonexclusive, nontransferable, paid up, royalty free license to access
         any PSC System as necessary in connection with the Services that the
         applicable PSC Entity is obligated to provide to the applicable SBC
         Entity under such EPI Agreement, subject to PSC Parent's right to
         grant such a license with respect to any PSC Systems licensed by PSC
         Parent.  PSC Parent, with the cooperation of SBC Parent, will use all
         commercially reasonable efforts to obtain any third party consents
         necessary for members of the SBC Group to access the PSC Systems as
         contemplated by the preceding sentence.  With respect to each EPI
         Agreement, provided that the SBC Entity is not in breach of that EPI
         Agreement and subject to PSC Parent's rights under any license
         agreement for any PSC System licensed by PSC Parent, PSC Parent will
         grant to that SBC Entity at the termination of that EPI Agreement
         possession of two (2) copies of the source code, user documentation
         and system documentation and a perpetual, nontransferable,
         nonexclusive, paid up, royalty free license to use the application
         software programs (including all related documentation) of any PSC
         Systems then being used by the applicable PSC Entity in providing the
         Services to the applicable SBC Entity (the "Licensed PSC Programs"),
         subject to the following:





                                       15
<PAGE>   16
         (a)     Except with the prior written consent of PSC Parent or to the
                 extent required by natural disaster or similar emergency, the
                 Licensed PSC Programs will not be operated, directly or
                 indirectly, (i) by persons other than employees of such SBC
                 Entity or a third party vendor providing services to any SBC
                 Entity, or (ii) on equipment that is not under the control of
                 any SBC Entity or a third party vendor providing services to
                 any SBC Entity.

         (b)     Except with the prior written consent of PSC Parent, the
                 Licensed PSC Programs may only be used for the internal
                 operations of the applicable SBC Entity.
         (c)     The SBC Entity will keep the Licensed PSC Programs
                 confidential, will not at any time allow the Licensed PSC
                 Programs, or any of the various components thereof or any
                 modifications thereto, to be disclosed to third parties, sold,
                 assigned, leased or commercially exploited or marketed in any
                 way, with or without charge, by the SBC Entity or its
                 employees or agents and, except to the extent required for
                 normal operation of the Licensed PSC Programs as permitted
                 herein, will not permit the Licensed PSC Programs to be copied
                 or reproduced, in whole or in part, by any Person, at any
                 time.
         (d)     The SBC Entity agrees that the Licensed Programs are the
                 valuable property of PSC Parent, that violation in any
                 material respect of any provision of this Section 4.3 would
                 cause PSC Parent irreparable injury for which it would have no
                 adequate remedy at law, and, in addition to any and all other
                 remedies or rights PSC Parent may have at law or in equity,
                 PSC Parent will be entitled to preliminary and other
                 injunctive relief against any such violation.

4.4      SBC Equipment.

         (a)     SBC Parent and PSC Parent acknowledge and agree that, except
                 for the rights granted to the applicable PSC Entity pursuant
                 to this Section 4.4, or as otherwise expressly agreed in an
                 EPI Agreement, all right, title and interest in and to the
                 Equipment is owned by and will continue to be owned by one or
                 more members of the SBC Group.

         (b)     During the term of each EPI Agreement and unless otherwise
                 provided for therein, the applicable SBC Entity will make
                 available to the applicable PSC Entity, for that PSC Entity's
                 use, at no charge except as provided in the last sentence of
                 this Section 4.4(b), all Equipment that is expressly
                 referenced in the applicable EPI Agreement as being provided
                 by the applicable SBC Entity to the applicable PSC Entity.
                 With respect to personal computers, modems, printers and
                 related personal Equipment used by Transitioned Employees
                 generally prior to the effective date of the applicable EPI
                 Agreement, the applicable PSC Entity will pay the applicable
                 SBC Entity for such use on a monthly basis for the
                 depreciation costs of that Equipment for that month until that
                 Equipment has been fully depreciated.

         (c)     Prior to the use by any PSC Entity of the Equipment for any
                 customer of that PSC Entity (other than a member of the SBC
                 Group), that PSC Entity will obtain the consent of the
                 applicable SBC Entity based upon a business case prepared by
                 the PSC Entity for the applicable SBC Entity's review and
                 approval specifying (i) any capital investment that will be
                 required from that SBC Entity to obtain any additional
                 resources to provide services to the customer of the PSC Group
                 and, if so, any payments that will be made to the applicable
                 SBC Entity in connection with or attributable to the use of
                 the Equipment; (ii) any impact on the overall operating
                 expenses of the Equipment; (iii) any impact the introduction
                 of the third party customer would have on existing Service
                 Levels; and (iv) any impact on the applicable PSC Entity's
                 charges to the applicable SBC Entity for the Services.  The
                 applicable PSC Entity will also satisfy the applicable SBC
                 Entity, in that SBC Entity's sole discretion, that adequate
                 Security Procedures have been instituted to prevent disclosure
                 of any Confidential Information of the SBC Group to the third
                 party customer.

4.5      Additional Equipment.  Any additional Equipment (other than personal
         computers, modems, printers and related personal Equipment used by PSC
         personnel) which a PSC Entity elects to add in order to provide the
         Services to an SBC Entity during the term of any EPI Agreement will be
         purchased in accordance with the terms of that EPI Agreement.

4.6      SBC Facilities.

         (a)     Commencing on the effective date of each EPI Agreement, the
                 applicable SBC Entity will provide to the applicable PSC
                 Entity such space, office furnishings, janitorial service,
                 telephone service, utilities (including air conditioning) and
                 office-related equipment, supplies, and duplicating services

                 reasonably require to provide the Services to the applicable
                 SBC Entity pursuant to that EPI Agreement, including the
                 space, furnishings, and equipment utilized by the applicable
                 Transitioned Employees prior to the effective date of that EPI
                 Agreement (under all EPI Agreements collectively, the "SBC
                 Facilities").  The employees of the applicable PSC Entity will
                 have reasonable access to the applicable SBC Facilities
                 twenty-four (24) hours a day, seven (7) days a week and will,
                 at all times, comply with the applicable SBC Entity's
                 reasonable physical security procedures while on the premises
                 of the SBC Facilities.  In addition, the applicable SBC Entity
                 will provide necessary storage space for backup data files and
                 will provide such additional storage space as may be required

                 regulatory authority with jurisdiction over the applicable SBC
                 Entity's business.

         (b)     The applicable PSC Entity will pay the applicable SBC Entity

<PAGE>   18
         (c)     Prior to relocating Services from any SBC Facility to any
                 other facility, the applicable PSC Entity will obtain the
                 consent of the applicable SBC Entity based upon a business
                 case prepared by the PSC Entity for the review and approval of
                 the SBC Entity, which approval will not be unreasonably
                 withheld.

         from time to time perform the Services pursuant to any EPI Agreement,
         including processing of the applicable SBC Entity's data, in
         facilities maintained by the PSC Group (under all EPI Agreements
         collectively, "PSC Facilities") as that PSC Entity deems appropriate,
         provided that the applicable SBC Entity must be and remain satisfied
         that adequate Security Procedures have been implemented and are being
         observed at the applicable PSC Facility.

4.6      Third Party Services Contracts.

         (a)     On or prior to the date each EPI Agreement (which for purposes
                 of this Section for the SBC Warburg EPI Agreement will be the
                 Original Agreement Date) is executed and again on or prior to
                 the effective date of that EPI Agreement, the applicable SBC
                 Entity will use reasonable efforts to provide the applicable
                 PSC Entity with a list of all Third Party Service Contracts
                 related to the Operational Management of the EPI of that SBC
                 Entity.  The applicable PSC Entity will assume responsibility
                 for the applicable Third Party Service Contracts as of the
                 effective date of the applicable EPI Agreement and any other
                 Third Party Service Contract to which an entity that is
                 acquired and becomes part of the SBC Warburg Division is a
                 party or to which a member of the SBC Group may become a party
                 after the effective date of the applicable EPI Agreement as
                 the result of an acquisition of any entity that becomes part
                 of an SBC Entity.  SBC Parent agrees that, until the
                 applicable PSC Entity assumes responsibility for any Third
                 Party Service Contract pursuant to an EPI Agreement, it will
                 manage all Third Party Service Contracts related to that EPI
                 Agreement to expire at the earliest reasonable opportunity
                 that does not result in a termination penalty.

         (b)     Commencing on the effective date of any EPI Agreement, unless
                 prohibited by the applicable Third Party Service Contract:

                 (1)      The applicable SBC Entity will make available to the
                          applicable PSC Entity during the term thereof, at a
                          charge to that PSC Entity equal to the amounts such
                          SBC Entity is obligated to pay under such Third Party
                          Service Contracts, the services provided by third
                          parties pursuant to each Third Party Service Contract
                          and utilized by the applicable SBC Entity prior to
                          the effective date of that EPI Agreement in
                          performing the services and functions assumed by the
                          PSC Entity thereunder.
                 (2)      The applicable PSC Entity will have administrative
                          and management responsibility for managing such third
                          party services to the same extent as if that PSC
                          Entity were the contracting party for such services
                          during the term





                                       18
<PAGE>   19
                          of that EPI Agreement.  The applicable SBC Entity
                          will retain sole authority to execute amendments to
                          the Third Party Service Contracts, but, unless that
                          SBC Entity and the applicable PSC Entity otherwise
                          agree, that SBC Entity will act to terminate those
                          Third Party Service Contracts at the earliest
                          available opportunity that does not result in a
                          termination penalty.

                 (3)      Nothing in this Section 4.8 will require an SBC
                          Entity to make available to a PSC Entity the services
                          under a Third Party Services Contract, grant to the
                          applicable PSC Entity management or administrative
                          responsibility for third party services, or assign or
                          terminate a Third Party Services Contract if the
                          terms of the applicable Third Party Services Contract
                          prohibit the applicable SBC Entity from doing so, or
                          if the applicable SBC Entity would subject itself to
                          a penalty by doing so.

4.9      Transfer of Personnel.  Unless otherwise provided in an EPI Agreement,
         commencing on the effective date of each EPI Agreement (which for the
         purposes of this Section  for the SBC Warburg EPI Agreement will be
         the Original Agreement Date), the applicable PSC Entity will offer
         employment to all employees of the applicable SBC Entity identified in
         that EPI Agreement in accordance with the transition plan described
         therein and otherwise in accordance with the applicable PSC Entity's
         normal employment policies.  PSC agrees that each Transitioned
         Employee will be offered a salary and benefits package that is
         substantially comparable to the salary and benefits package received
         by that Transitioned Employee prior to the effective date of that EPI
         Agreement.  Should a PSC Entity request that the applicable SBC Entity
         continue to make payments to such employees after they are hired by
         such PSC Entity, as an administrative convenience and until such
         personnel can be integrated into the PSC payroll system, the
         applicable SBC Entity  will do so for a reasonable period not to
         exceed three (3) months, subject to reimbursement therefor and
         appropriate indemnification by the applicable PSC Entity.  In such
         event, the SBC Entity will be acting solely as the PSC Entity's agent
         and the applicable PSC Entity will reimburse the applicable SBC Entity
         for all wages paid and employer's contributions made by such SBC
         Entity in connection therewith.

4.10     Resource Payments.  The applicable PSC Entity will reimburse the
         applicable SBC Entity pursuant to the applicable EPI Agreement for the
         amounts due with respect to this Article IV by issuing to that SBC
         Entity a credit against that SBC Entity's invoices for such amounts.
         Any credit due to an SBC Entity pursuant to this Section 4.10 will be
         given by the PSC Entity in the next succeeding month after the month
         in which the credit is determined.

                 right, title and interest in and to all SBC Data.  Upon the
                 termination of this Agreement or of any EPI Agreement for any
                 reason or, with respect to any SBC Data, on such earlier date
                 as the applicable SBC Entity and the applicable PSC Entity
                 mutually determine that any of the same will no longer be
                 required by that PSC Entity in order to render Services to
                 such SBC Entity, such SBC Data will be either erased from the
                 data files maintained by each member of the PSC Group or, if
                 the applicable SBC Entity so elects, returned to such SBC
                 Entity.  SBC Data may not be utilized by any member of the PSC
                 Group for any purpose except to provide Services to the
                 members of the SBC Group, nor may SBC Data or any part thereof
                 be disclosed, sold, assigned, leased or otherwise disposed of
                 to third parties by any member of the PSC Group or
                 commercially exploited by or on behalf of any member of the
                 PSC Group, or any of its employees or agents.

         (b)     The parties hereto acknowledge and agree that, in connection
                 with each EPI Agreement, unless the applicable SBC Entity is
                 satisfied that its security concerns are adequately addressed,
                 that EPI Agreement will provide that that SBC Entity will
                 retain exclusive supervisory control of the systems and
                 personnel required to ensure that the confidentiality and
                 secrecy of SBC Data will be maintained; provided that if that
                 EPI Agreement provides that such SBC Entity will retain
                 control over the systems and personnel, the members of the PSC
                 Group will be excused from its Service and Service Level
                 obligations to the extent that such retention by the SBC
                 Entity prevents, materially hinders or delays the members of
                 the PSC Group from providing the Services or meeting any
                 applicable Service Level as set forth in such EPI Agreement.
                 Without the consent of the applicable SBC Entity, Information
                 Technology related security-related functions or crypto codes
                 will not be shared by any member of the SBC Group with any
                 member of the PSC Group and only personnel of members of the
                 SBC Group will execute such functions.

         (c)     PSC Parent agrees that if any employee of any member of the
                 PSC Group who is providing Services to the SBC Group is
                 granted access by a member of the SBC Group to (i) any
                 facility at which customer or customer-related data of any
                 member of the SBC Group is located, or (ii) any Systems upon
                 which any customer or customer-related data of any member of
                 the SBC Group is contained, that employee will, upon the
                 request of the applicable member of the SBC Group, be required
                 to execute an agreement (and amendments to that agreement as
                 required to comply with this Section 5.1(c)) that contains
                 provisions requiring that employee to





                                       20
<PAGE>   21
                 maintain the confidentiality of all customer or
                 customer-related data of any member of the SBC Group, which
                 provisions will be no more restrictive than the
                 confidentiality provisions contained in any agreement that the
                 members of the SBC Group generally require their employees,
                 contractors and agents with similar access to execute from
                 time to time.

5.2      Safeguarding SBC Data.  With respect to, and under the terms and
         conditions of, each EPI Agreement, the applicable PSC Entity will
         establish and maintain safeguards against the destruction, loss or
         alteration of SBC Data in the possession of any member of the PSC
         Group which are no less rigorous than those in effect at the
         applicable SBC Facilities as of the effective date of that EPI
         Agreement.  In the event that additional safeguards for SBC Data are
         reasonably requested by the SBC Entity, the applicable PSC Entity will
         provide those additional safeguards and that SBC Entity will pay that
         PSC Entity therefor in accordance with the payment terms provided in
         the applicable EPI Agreement.  An SBC Entity will have the right to
         establish backup security for data and to keep backup data and data
         files in its possession if it so chooses; provided, however, that the
         applicable PSC Entity will have access to such backup data and data
         files as is reasonably required by that PSC Entity to provide the
         Services.  Each PSC Entity's access to such data and data files must
         be consistent with the Security Procedures.

5.3      Physical Security for Facilities.  With respect to, and under the
         terms and conditions of, each EPI Agreement, the applicable PSC Entity
         will perform all reasonably required security procedures at any place
         where Services are performed by that PSC Entity.  The procedures at
         the SBC Facilities will be no less rigorous than those in effect there
         as of the effective date of that EPI Agreement.  The applicable SBC
         Entity will provide all necessary security personnel and security
         equipment at the SBC Facilities.  Personnel of members of the PSC
         Group will comply with the reasonable physical security procedures of
         members of the SBC Group with respect to access to any SBC Facilities,
         data and data files.


5.4      Audit Rights.  The members of the SBC Group and/or its independent
         auditors (who shall not be PSC Competitors (as defined in the Master
         Agreement) or Affiliates of PSC Competitors, other than the reporting
         auditors of the applicable member of the SBC Group), at no additional
         expense to any member of the PSC Group, and upon ten (10) business
         days' written notice to the applicable member of the PSC Group, will
         have the right to conduct an operational audit pertaining to Services
         rendered pursuant to this Agreement or any EPI Agreement, including
         but not limited to having the members of the PSC Group process through
         any system test data supplied by a member of the SBC Group or its
         auditors, operate audit software on any System, download SBC Data to a
         computer designated by the applicable member of the SBC Group or its
         auditors, or conduct a System backup and disaster recovery audit.  The
         purpose of the operational audit will be to verify that each member of
         the PSC Group is exercising reasonable data processing operational
         procedures in its performance of the Services and confirm that each
         member of the PSC Group is performing and observing its obligations
         hereunder or under the applicable EPI Agreement.  The report resulting
         from each operational audit will be reviewed by the applicable SBC
         Entity and the applicable PSC Entity and appropriate actions will be
         taken





                                       21
<PAGE>   22
         based upon each such review.  The members of the PSC Group will
         provide to such auditors and inspectors any assistance that they
         reasonably require, and the costs incurred by the members of the PSC
         Group in connection with services rendered in connection with any such
         audit or inspection will be included in the PSC Costs in accordance
         with the terms of the applicable EPI Agreement.

5.5      Disaster Recovery.  During the term of each EPI Agreement, the
         applicable PSC Entity will maintain and continue to maintain
         throughout the term of that EPI Agreement, an off-site disaster
         recovery capability, including a disaster recovery plan, as mutually
         agreed in connection with that EPI Agreement.  In the event of a
         disaster affecting the Services provided by the PSC Entity pursuant to
         any EPI Agreement, the PSC Entity will implement the disaster recovery
         plan applicable to that EPI Agreement.  The costs incurred by the PSC
         Entity in connection with any disaster recovery Services provided by
         that PSC Entity as described in this Section 5.5 will be included in
         the PSC Costs in accordance with the provisions of the applicable EPI
         Agreement.

5.6      Regulatory Access.  The parties agree that the records maintained and
         produced under this Agreement and any EPI Agreement will at all times
         be available for examination and audit by governmental agencies,
         regulators or exchanges of which any member of the SBC Group is a
         member having jurisdiction over the business of any member of the SBC
         Group.  Each party to this Agreement will notify the other party
         promptly of any formal request by an authorized governmental agency,
         regulator or exchange to examine records regarding any member of the
         SBC Group that are maintained by any member of the PSC Group.  Upon
         the written request of any member of the SBC Group, the applicable
         member of the PSC Group will provide any relevant assurances to such
         agencies, regulators or exchanges and will subject itself to any
         required examination or regulation, and the costs incurred by the
         applicable member of the PSC Group for any services rendered in
         connection with any such examination will be included in the PSC Costs
         in accordance with the applicable EPI Agreement.

5.7      Viruses.  Each party will use its reasonable efforts to ensure that no
         viruses, worms or similar items ("Viruses") are introduced into any
         System used under this Agreement or any EPI Agreement.  If a Virus is
         found in any such System, the applicable PSC Entity will, promptly
         upon the discovery thereof, use its best efforts to eliminate such
         Virus and ameliorate the effect thereof.  If a Virus causes a loss of
         operational efficiency or data, the applicable PSC Entity will
         mitigate and restore such loss as quickly as feasible.

5.8      Disabling Code.  No System provided by either any member of the SBC
         Group or any member of the PSC Group will include, nor will any member
         of the PSC Group or any member of the SBC Group introduce into any
         System, any code with the purpose to disable or reduce the efficiency
         of all or any portion of any System.

                                   MANAGEMENT

6.1      Relationship Managers.  Each party (an "Appointing Party") will
         appoint an individual (a "Relationship Manager") who, until replaced
         by the Appointing Party, will serve as that Appointing Party's
         representative under this Agreement.  Each Relationship Manager will
         (i) have overall responsibility for managing and coordinating the
         performance of the Appointing Party's obligations under this
         Agreement, (ii) be authorized to act for and on behalf of the
         Appointing Party with respect to all matters relating to this
         Agreement, and (iii) work with the Operational Managers for the SBC
         Entities or the PSC Entities, as applicable, to establish appropriate
         uniform procedures for the Services to be provided by the members of
         the PSC Group to the members of the SBC Group. Neither party will
         reassign its Relationship Manager or cause its Relationship Manager to
         no longer serve in that capacity without the other party's prior
         consent, which consent will not be unreasonably withheld.  Each party
         further agrees that if its Relationship Manager ceases to be employed
         by that party, or is reassigned, such party's Relationship Manager may
         only be replaced with the consent of the other party, which consent
         will not be unreasonably withheld.

6.2      Operational Managers.  Each Contracting Party to an EPI Agreement will
         appoint an individual (an "Operational Manager") who will serve as
         that Contracting Party's representative under that EPI Agreement.
         Each Operational Manager will (i) have overall responsibility for
         managing and coordinating the performance of the Contracting Party's
         obligations under that EPI Agreement and (ii) be authorized to act for
         and on behalf of the Contracting Party with respect to all matters
         relating to that EPI Agreement.  No Contracting Party may reassign its
         Operational Manager or cause its Operational Manager to no longer
         serve in that capacity without the other Contracting Party's prior
         consent, which consent will not be unreasonably withheld.  Each
         Contracting Party further agrees that if its Operational Manager
         ceases to be employed by that Contracting Party, or is reassigned,
         that Contracting Party's Operational Manager may only be replaced with
         the other Contracting Party's consent, which consent will not be
         unreasonably withheld.

6.3      Change Control Procedures.  Within one hundred and eighty (180) days
         after the effective date of each EPI Agreement and as part of the
         Services provided by the applicable PSC Entity under that EPI
         Agreement, that PSC Entity and the applicable SBC Entity will mutually
         establish  a written description of the change control procedures that
         will be applicable to any Changes related to that EPI Agreement.  For
         the purpose of this Section 6.3, "Changes" are any changes to the
         Systems, the Equipment or the Services that would materially alter the
         functionality, Service Levels or technical environment of the Systems
         or the Equipment, or the manner in which the Services are provided or
         the composition of the Services.  These change control procedures will
         provide that, except for Changes made on a temporary basis to maintain
         the continuity of the Services, the applicable SBC Entity and the
         applicable PSC Entity will implement Changes only after consultation
         and agreement between the applicable SBC Entity and the applicable PSC
         Entity.

6.4      Crisis Management Procedures.  In connection with each EPI Agreement,
         the applicable PSC Entity and the applicable SBC Entity will establish
         a procedure for immediately escalating to a team of appropriate senior
         level managers or officers, including the Relationship Manager for
         each party, any significant technical problem that may arise from time
         to time that, if not quickly resolved, could have a negative impact on
         critical portions of that SBC Entity's business.  This procedure will,
         at a minimum, provide that in the event of a major service outage,
         then:

         (a)     The production manager for the applicable PSC Entity, who will
                 be available on a seven (7) days a week, twenty-four (24)
                 hours a day basis will be notified of all details of the
                 outage.  If that production manager is not able to implement a
                 plan to resolve the outage within two (2) hours of receipt of
                 notice, then;

         (b)     The crisis manager for the applicable PSC Entity and the
                 President of PSC Parent will be notified and a hot line will
                 be established to provide continuous information with respect
                 to the status of the outage and estimated time of repair.  If
                 the outage is not resolved within two (2) hours of the crisis
                 manager being notified, then;

         (c)     A crisis management "SWAT" team, consisting of personnel of
                 the applicable PSC Entity and personnel of the applicable SBC
                 Entity, will be formed and the Chairman of PSC Parent will be
                 notified.  Every hour on the hour, until the outage is
                 resolved, there will be bridged status report calls from the
                 "SWAT" team to key managers of the applicable PSC Entity and
                 the applicable SBC Entity and PSC Parent and SBC Parent.


                                  ARTICLE VII
                   PERFORMANCE REVIEW AND DISPUTE RESOLUTION


7.1      Scope. The dispute resolution procedures specified in Sections 7.2 and
         7.3 hereof will apply to all matters arising out of this Agreement and
         each EPI Agreement that relate to technical matters such as Service
         Levels and to the performance of Services. With respect to any other
         dispute arising under this Agreement or any EPI Agreement, including,
         without limitation, compliance by the members of the PSC Group with
         the Security Procedures or the payment of PSC invoices, the applicable
         Contracting Parties will have immediate recourse to the arbitration
         provisions of Section 7.4 hereof.  The parties agree that PSC Costs
         (as defined in each EPI Agreement) will not include the fees and
         charges of legal counsel (outside or internal) incurred in connection
         with any enforcement action, formal dispute resolution procedure or
         formal court or arbitration proceedings against an SBC Entity or in
         connection with the determination of whether any such action,
         procedure or proceeding should be initiated or defended.

7.2      Performance Review.  The Relationship Managers will meet as often as
         either Relationship Manager reasonably requests to review the
         performance of the PSC Group under this Agreement and each EPI
         Agreement.  Subject to the provisions of Section 7.1 hereof, in the
         event of any dispute or disagreement between the parties hereto, upon
         the written request of either party, each party will appoint an equal
         number of designated officers, plus both Relationship Managers
         (collectively, the "Special Resolution Committee"), whose task it will
         be to meet for the purpose of endeavoring to resolve such dispute or
         to negotiate for an adjustment to the relevant provisions of this
         Agreement or the applicable EPI Agreement.  The Special Resolution
         Committee will meet as often as the parties reasonably deem necessary
         in order to gather and furnish to the members of the Special
         Resolution Committee all information with respect to the matter at
         issue which either party believes to be appropriate and germane in
         connection with its resolution.  The Special Resolution Committee will
         discuss the problem and/or negotiate in good faith in an effort to
         resolve the dispute or renegotiate the applicable section or provision
         without the necessity of any further proceeding relating thereto.
         During the course of the negotiation, all reasonable requests made by
         one party to the other for information relating to the dispute and the
         resolution thereof will be honored.  The specific format for such
         discussions will be left to the discretion of the Special Resolution
         Committee, but may include the preparation of agreed upon statements
         of fact or written statements of position furnished to the other
         party.  No further proceedings for the resolution of any dispute may
         be commenced until the earlier of (i) the date on which a majority of
         the members of the Special Resolution Committee conclude in good faith
         that an amicable resolution through continued negotiation of the
         matter in issue does not appear likely, or (ii) thirty (30) days from
         the date the dispute was submitted to the Special Resolution
         Committee.

7.3      Escalation of Disputes.  Subject to the provisions of Section 7.1
         hereof, any dispute that is not resolved by the Special Resolution
         Committee in accordance with the procedures described in Section 7.2
         above will be escalated to the Chief Executive Officers of PSC Parent
         and SBC Parent, who will each appoint one (1) corporate officer to
         discuss the problem and negotiate in good faith to resolve the dispute
         or controversy.  The specific format for such discussions and
         negotiations will be left to the discretion of the two (2) appointed
         corporate officers.  No further proceedings for the resolution of any
         dispute may be commenced until the earlier of (i) the date on which
         the two (2) appointed directors conclude in good faith that a
         resolution to the dispute through continued negotiations is not
         likely, or (ii) thirty (30) days from the date the dispute was
         escalated to the Chief Executive Officers of PSC Parent and SBC
         Parent.

7.4      Arbitration.  Subject to Section 7.1 hereof, any dispute that is not
         resolved through negotiation pursuant to Sections 7.2 or 7.3 hereof
         will be settled exclusively by final and binding arbitration in
         accordance with the following:

         (a)     Except as specified below or otherwise mutually agreed in
                 writing by the parties to the dispute, the arbitration will be
                 conducted in accordance with the then current Commercial
                 Arbitration Rules of the American Arbitration Association.





                                       25
<PAGE>   26
         (b)     Any demand for arbitration or any counterclaim will specify in
                 reasonable detail the facts and legal grounds forming the
                 basis for the claimant's request for relief, and will include
                 a statement of the total amount of damages claimed, if any,
                 and any other remedy sought by the claimant.

         (c)     The arbitration will be conducted by an arbitration panel
                 consisting of three neutral arbitrators selected in accordance
                 with those Commercial Arbitration Rules.  The arbitration will
                 be conducted in the English language.

         (d)     The arbitration proceedings will take place in New York.

         (e)     The arbitration panel may render awards of monetary damages,
                 direction to take or refrain from taking action, or both.
                 However, the arbitration panel may not award monetary damages
                 in excess of compensatory damages and will in no event award
                 any damages not permitted by Sections 10.6 and 10.7 hereof.

         (f)     The arbitration panel may, at its discretion, require any
                 party to the arbitration to reimburse any other party to the
                 arbitration for all or any part of the expenses of the
                 arbitration paid by the other party and the attorneys' fees
                 and other expenses reasonably incurred by the other party in
                 connection with the arbitration.

         (g)     Judgment upon the award rendered in the arbitration may be
                 entered in any court of competent jurisdiction.

         (h)     The parties will direct the arbitration panel to reach a
                 decision within one hundred and eighty (180) days of the date
                 on which the parties submit the dispute for resolution
                 pursuant to this Section 7.4.

7.5      Injunctive Relief. Nothing in this Article VII will prevent any
         Contracting Party from immediately seeking injunctive or other
         equitable relief, including termination under Article VIII hereof,
         from any court having competent jurisdiction.

7.6      Continued Performance.  Unless the applicable EPI Agreement has been
         terminated in accordance with the provisions of Article VIII hereof,
         the applicable PSC Entity will continue to provide the Services
         contemplated by that EPI Agreement during any dispute resolution or
         arbitration proceedings commenced pursuant to this Article VII,
         provided that the applicable SBC Entity will continue to make payment

                                  ARTICLE VIII
                                  TERMINATION

8.1      Termination for Cause.  In the event that a Contracting Party
         materially defaults in the performance of any of its duties or
         obligations under this Agreement or under an EPI Agreement, which
         default is not substantially cured within sixty (60) days after
         written notice is given to the defaulting Contracting Party specifying
         the default (or, with respect to any such default which cannot
         reasonably be cured within such sixty (60) day period but is curable,
         (x) if the defaulting Contracting Party fails to proceed within such
         sixty (60) day period to commence curing the default and thereafter to
         proceed with all due diligence to substantially cure the same, or (y)
         if any such default referenced in clause (x) is not substantially
         cured within one hundred twenty (120) days after the giving of such
         written notice), then the non-defaulting Contracting Party may
         terminate this Agreement and the applicable EPI Agreement on the date
         specified in such notice of termination, which date will be no later
         than one (1) year after the date on which that Contracting Party's
         right to terminate this Agreement and the applicable EPI Agreement
         arose.

8.2      Termination for Non-Payment.  In the event that an SBC Contracting
         Party defaults in the payment when due of any amount in excess of
         $500,000 due to a PSC Contracting Party under any EPI Agreement, and
         does not cure the default within thirty (30) days after being given
         written notice of the default, then the applicable PSC Contracting
         Party may, by giving written notice thereof to that SBC Contracting
         Party, terminate the applicable EPI Agreement as of a date specified
         in the notice of termination, which date will be no later than one (1)
         year after the date on which that PSC Contracting Party's right to
         terminate this Agreement or the applicable EPI Agreement arose.

8.3      Termination for Insolvency.  In the event that a Contracting Party
         (the "Insolvent Party") becomes or is declared insolvent or bankrupt,
         is the subject of any proceedings relating to its liquidation,
         insolvency or for the appointment of a receiver or similar officer for
         it (which, in the case of involuntary proceedings, remains undismissed
         for at least sixty (60) days), makes an assignment for the benefit of
         all or substantially all of its creditors, or enters into an agreement
         for the composition, extension, or readjustment of all or
         substantially all of its obligations, then the other applicable
         Contracting Party may, by giving written notice thereof to the
         Insolvent Party, terminate this Agreement and each EPI Agreement as of
         a date specified in such notice of termination.  Neither this
         Agreement nor any EPI Agreement may be terminated pursuant to this
         Section 8.3 once the Insolvent Party ceases to be insolvent or be the
         subject of a proceeding relating to its liquidation, insolvency or the
         appointment of a receiver.

8.4      Termination for PSC Change in Control.  In the event that a Change in
         Control occurs in a single transaction or series of related
         transactions, then the applicable SBC Entity will have the right to
         terminate this Agreement and the applicable EPI Agreement, if such
         Change in Control is reasonably likely to have a significant adverse
         impact on the performance of or the charges for the Services generally
         rendered by the applicable PSC Entities under all EPI





                                       27
<PAGE>   28
         Agreements or rendered by the applicable PSC Entity pursuant to that
         EPI Agreement, by giving that PSC Entity at least ninety (90) days
         prior written notice designating the termination date on which this
         Agreement or that EPI Agreement will terminate if such Change in
         Control has not been cured by such date; provided, however, that the
         date specified in such termination notice will be no later than one
         (1) year after the Change in Control occurred.

8.5      Termination for Change of Circumstances.  The applicable SBC Entity
         may terminate this Agreement and the applicable EPI Agreement in the
         event that the members of the PSC Group cease generally to offer IT
         Services (other than to existing customers with non-terminable
         contracts) by giving at least sixty (60) days prior written notice to
         the applicable PSC Entity specifying the date on which that SBC Entity
         intends to terminate this Agreement and the applicable EPI Agreement,
         which date will be no later than one (1) year after the date on which
         the SBC Entity's right to terminate this Agreement or that EPI
         Agreement arose.

8.6      Termination for Cross-Default.  With respect to each EPI Agreement,
         either Contracting Party may, by giving prior written notice to the
         other, terminate that EPI Agreement in the event there has been a
         termination (as a result of a breach by a PSC Entity or an SBC Entity,
         as the case may be) of another EPI Agreement between a PSC Entity and
         an SBC Entity or of an agreement between the other and a third entity,
         in each case, with annual revenues at least equal to the annual
         revenues from the EPI Agreement to be terminated.  No EPI Agreement
         may be terminated for such cross-default more than one (1) year after
         the date on which the right to terminate pursuant to this Section 8.6
         arose.

8.7      Termination for SBC Major Event.  The applicable SBC Entity may, by
         giving one hundred eighty (180) days' prior written notice to the
         applicable PSC Entity, terminate this Agreement and the applicable EPI
         Agreement in the event that SBC Parent is merged into, is acquired by
         or acquires another significant entity (an "Acquiring Entity") with a
         market value equal to at least fifty percent (50%) of SBC Parent's
         market value which has a nonterminable significant exclusive
         information technology services contract with annual revenues to the
         other provider (the "Other IT Provider) of at least fifty percent
         (50%) of the annual revenues to the members of the PSC Group from the
         members of the SBC Group under all EPI Agreements, the absence of
         which would have a material adverse effect on the combined entity and
         the members of the SBC Group choose to contract with the Other IT
         Provider for the work formerly performed by the members of the PSC
         Group, provided that the parties agree that they will use their best
         efforts to find a solution acceptable to both the members of the SBC
         Group and the members of the PSC Group other than terminating an EPI
         Agreement.  If such Acquiring Entity has a nonterminable non-exclusive
         contract with the Other IT Provider, the members of the SBC Group will
         be permitted to continue such contract.  Neither this Agreement nor
         any EPI Agreement may be terminated for such event more than one year
         after the date on which either party determines that a solution
         acceptable to both parties as described above will not be found.

8.8      [Intentionally omitted.]

8.9      Termination for Security Breach.  The applicable SBC Entity may
         terminate  the applicable EPI Agreement if (i) the applicable PSC
         Entity fails to cure, within ten (10) days after written notice is
         given to it by the applicable SBC Entity, a curable breach of the
         Security Procedures that has a material adverse effect on the business
         or reputation of the members of the SBC Group, or (ii) the applicable
         PSC Entity commits a non-curable breach of the Security Procedures
         that has a material adverse effect on the  business or reputation of
         the members of the SBC Group and the applicable PSC Entity has not,
         within thirty (30) days after written notice of the breach is given to
         it by the applicable SBC Entity, implemented a plan to prevent a
         substantially similar breach, except that if the non-curable breach
         occurs on two additional occasions, the applicable SBC Entity may
         terminate  the EPI Agreement under which such breach arose.

8.10     Rights Upon Termination of EPI Agreements.  Upon termination of any
         EPI Agreement, and for a period of eighteen (18) months thereafter,
         each Contracting Party thereto will have the following rights and
         obligations:

         (a)     Commencing upon any notice of termination by any member of the
                 SBC Group pursuant to Sections 8.1, 8.3, 8.4, 8.5, 8.6, 8.7,
                 8.9 or 10.7(a) hereof or expiration of the term of that EPI
                 Agreement, the applicable PSC Entity will comply with the
                 applicable SBC Entity's reasonable directions, and will
                 provide to such SBC Entity any and all termination assistance
                 reasonably requested to allow the Services provided under that
                 EPI Agreement to continue and to facilitate the orderly
                 transfer of responsibility for performance of the Services to
                 the members of the SBC Group or a third party designated by
                 SBC Parent.  The applicable SBC Entity will pay the applicable
                 PSC Entity for such assistance in accordance with the terms of
                 the applicable EPI Agreement.  The termination assistance to
                 be provided in accordance with this Section 8.10 may include
                 the following:

                 (1)      Continuing to perform, following the termination
                          date, any or all of the Services in accordance with
                          all applicable Service Levels then being performed by
                          that PSC Entity.

                 (2)      Developing, together with that SBC Entity, a plan for
                          the orderly transition of the performance of the
                          Services from that PSC Entity to that SBC Entity or a
                          third party designated by SBC Parent.

                 (3)      Providing reasonable training for personnel of that
                          SBC Entity or a third party designated by SBC Parent
                          in the performance of the Services then being
                          transitioned to that SBC Entity or a third party
                          designated by SBC Parent.

                 (4)      Providing that SBC Entity the right to assume any
                          leases for Equipment leased by that PSC Entity or to
                          purchase from that PSC Entity Equipment owned by that
                          PSC Entity that is then dedicated to providing
                          Services for





                                       29
<PAGE>   30
                          the SBC Entity pursuant to that EPI Agreement.  If
                          that SBC Entity exercises this right, it will pay to
                          the applicable PSC Entity an amount equal to such PSC
                          Entity's net book value of the applicable Equipment
                          calculated in accordance with generally accepted
                          accounting principles.

         (b)     If, upon the expiration or termination of an EPI Agreement, a
                 PSC Entity is using any Equipment to provide services to a
                 third party customer of the PSC Group, such PSC Entity may
                 continue to use that Equipment in accordance with Section 4.4
                 hereof until such time as the PSC Entity can reasonably
                 transition to other equipment, but for no more than eighteen
                 (18) months after termination.

         (c)     Following the termination of an EPI Agreement, the applicable
                 member of the PSC Group and the applicable member of the SBC
                 Group will have the right to solicit for employment and employ
                 any of its former employees then employed by the other.

8.11     Escrow Upon Termination.  If any EPI Agreement is terminated by an SBC
         Contracting Party pursuant to the provisions of Sections 8.1, 8.4,
         8.5, 8.6 or 8.9 hereof, PSC Parent will create an escrow in accordance
         with the procedures described in Schedule A hereto.


                                   ARTICLE IX
                                CONFIDENTIALITY

9.1      General Obligations.  All Confidential Information relating to any
         member of the SBC Group or the PSC Group will be held in confidence by
         the other to the same extent and in at least the same manner as such
         party protects its own confidential or proprietary information.  No
         member of the PSC Group or the SBC Group may disclose, publish,
         release, transfer or otherwise make available Confidential Information
         of the other party in any form to, or for the use or benefit of, any
         Person without the other party's written consent.  Each member of the
         PSC Group and each member of the SBC Group will, however, be permitted
         to disclose relevant aspects of the other party's Confidential
         Information to its respective officers, agents, subcontractors and
         employees and to the officers, agents, subcontractors and employees of
         its Affiliates to the extent that such disclosure is reasonably
         necessary for the performance of its duties and obligations under this
         Agreement or any EPI Agreement; provided, however, that such party
         will take all reasonable measures to ensure that Confidential
         Information of the other party is not disclosed or duplicated in
         contravention of the provisions of this Agreement or any EPI Agreement
         by such officers, agents, subcontractors and employees.  PSC Parent
         agrees that it will cause each employee of each member of the PSC
         Group providing Services to any member of the SBC Group to execute a
         PSC Parent confidentiality agreement, which will require confidential
         treatment of nonpublic information of and about customers of members
         of the PSC Group (which shall include members of the SBC Group).  Each
         member of the PSC Group or of the SBC Group, as the case may be, may
         disclose Confidential Information of the other party if required
         pursuant to an order or





                                       30
<PAGE>   31
         requirement of a court, administrative agency or other governmental
         body, regulator or exchange of which that SBC Entity is a member,
         provided that the applicable member of the PSC Group or the SBC Group,
         as the case may be, will (i) give the other party written notice of
         such order or requirement as soon as practicable after it has
         knowledge thereof and in any event prior to disclosure of the
         Confidential Information, (ii) disclose no more Confidential
         Information than is required by such order or requirement, and (iii)
         seek confidential treatment from the court, administrative agency or
         other governmental body for that Confidential Information.  Nothing in
         this Section 9.1 will prevent any Contracting Party from exercising
         its rights pursuant to Sections 4.1, 4.2 and 4.3 hereof.  Subject to
         any obligation of any member of the PSC Group to continue to provide
         termination assistance in accordance with Section 8.10 hereof and
         subject to each party's rights under Sections 4.1, 4.2 and 4.3 hereof,
         upon the termination of this Agreement or any EPI Agreement, the
         members of the PSC Group or the SBC Group, as the case may be, will
         return to the members of the SBC Group or the PSC Group, as the case
         may be, and at the other's expense, any Confidential Information of
         the other party then held by the members of the SBC Group or of the
         PSC Group, as the case may be.  The obligations of the members of PSC
         Group under this Section 9.1 are in addition to any obligations it has
         under Articles IV and V hereof and any obligations it has to comply
         with the Security Procedures.

9.2      Unauthorized Acts.  Each member of the PSC Group and each member of
         the SBC Group will:

         (a)     Notify the other promptly of any material unauthorized
                 possession or use of the other's Confidential Information by
                 any Person which may become known to such party, if such
                 unauthorized possession arose as a result of the acts or
                 failures to act of the notifying party.

         (b)     Promptly furnish to the other full details of the unauthorized
                 possession or use, and use reasonable efforts to assist the
                 other in investigating or preventing the recurrence of any
                 unauthorized possession or use of Confidential Information.

         (c)     Use reasonable efforts to cooperate with the other in any
                 litigation and investigation against third parties deemed
                 necessary by the other to protect its Confidential
                 Information.

         (d)     Promptly use all reasonable efforts to prevent a recurrence of
                 any such unauthorized possession or use of Confidential
                 Information.

                           INDEMNITIES AND LIABILITY


10.1     Cross Indemnity.  PSC Parent and SBC Parent each agree to indemnify,
         defend and hold harmless the other and the other's Affiliates from any
         and all claims, actions, losses,





                                       31
<PAGE>   32
         damages, liabilities, costs and expenses, including reasonable
         attorneys' fees and expenses, arising out of or relating to the death
         or bodily injury of any agent, employee, customer, business invitee or
         business visitor of the indemnitor or its Affiliates, or arising out
         of or relating to loss of or damage to tangible real or tangible
         personal property, to the extent that such claim, action, liability,
         loss, damage, cost or expense was proximately caused by the
         indemnifying party's tortious act or omission, or by those of its
         agents or employees.  For purposes of this Section 10.1, no
         Transitioned Employee to whom any member of the SBC Group continues to
         make payments pursuant to Section 4.9 hereof will be deemed to be an
         employee of the SBC Group solely as a result of those payments.

10.2     Intellectual Property Indemnity.

         (a)     PSC Parent and SBC Parent each agree to indemnify, defend and
                 hold harmless the other and the other's Affiliates from any
                 and all claims, actions, damages, liabilities, costs and
                 expenses, including reasonable attorneys' fees and expenses,
                 arising out of any claims of infringement of any patent, or a
                 trade secret, or any copyright, trademark, service mark, trade
                 name or similar proprietary rights conferred by contract or by
                 common law or by any law of any applicable jurisdiction
                 alleged to have resulted from the use of Systems provided by
                 the indemnitor or its Affiliates under this Agreement or any
                 EPI Agreement; provided, however, that, subject to Section
                 10.5 hereof, this indemnity will not apply unless the party
                 claiming indemnification notifies the other promptly of any
                 matters in respect of which the foregoing indemnity may apply
                 and of which the notifying party has knowledge and gives the
                 other full opportunity to control the response thereto and the
                 defense thereof, including, without limitation, any agreement
                 relating to the settlement thereof.

         (b)     PSC Parent will indemnify, defend and hold harmless the
                 members of the SBC Group from any and all claims, actions,
                 damages, liabilities, costs and expenses, including reasonable
                 attorneys' fees and expenses, arising out of any claims of
                 infringement of any patent, or a trade secret, or any
                 copyright, trademark, service mark, trade name or similar
                 proprietary rights conferred by contract or by common law or
                 by any law of any applicable jurisdiction resulting from use
                 of a Licensed SBC System provided by  a member of the PSC
                 Group to a third party customer of the PSC Group (other than
                 members of the SBC Group) in accordance with the provisions of
                 Article IV of this Agreement.

10.3     SBC Indemnity.  SBC Parent agrees to indemnify, defend and hold
         harmless the members of the PSC Group from any and all claims,
         actions, damages, losses, liabilities, costs and expenses, including
         reasonable attorneys' fees and expenses, arising out of (i) any claims
         for rent or utilities at any location where SBC is required to furnish
         space and/or utilities to PSC pursuant to this Agreement or any EPI
         Agreement, (ii) any claim arising in connection with the Equipment,
         SBC Facilities, SBC Systems, Transitioned Personnel or the Third Party
         Service Contracts, to the extent such claim under this subsection (ii)
         arose on or prior to the effective date of the applicable EPI
         Agreement, and (iii) any investigations,





                                       32
<PAGE>   33
         proceedings or other activities undertaken by any European fiscal
         authority with respect to this Agreement or any EPI Agreement (except
         as a result of the gross negligence or willful misconduct of a member
         of the PSC Group).

10.4     VAT Indemnity.

         (a)     If, pursuant to this Agreement or any EPI Agreement:

                 (1)      Any member of the PSC Group makes a supply or is
                          deemed or treated by applicable law or the practice
                          from time to time of any European fiscal authority to
                          make a supply to any member of the SBC Group, and
                          European VAT is chargeable in respect of such supply,
                          and as a result any member of the PSC Group is
                          required to account to any European fiscal authority
                          for such European VAT ("SBC Supply Vat"); or

                 (2)      Either of PSC Parent, on the one hand, or any other
                          member of the PSC Group, on the other, makes or is
                          deemed or treated by applicable law or the practice
                          from time to time of any European fiscal authority to
                          make a supply to the other in connection with this
                          Agreement or any EPI Agreement, and European VAT
                          ("Perot Supply VAT") is payable in respect of such
                          supply;

                 then, SBC Parent will on demand pay to the applicable member
                 of the PSC Group a sum equal to the amount of the SBC Supply
                 VAT or the Perot Supply VAT, as the case may be; provided,
                 that, in the latter case, SBC Parent's liability will not
                 extend to any Perot Supply VAT for which PSC Parent or the
                 applicable member of the PSC Group, as the case may be, is
                 entitled to credit or repayment from any European fiscal
                 authority.

         (b)     Where PSC Parent or any member of the PSC Group obtains a
                 repayment or credit in respect of Perot Supply VAT more than
                 one (1) month after the prescribed accounting period in which
                 that Perot Supply VAT was incurred, SBC Parent will pay
                 interest to PSC Parent or the applicable member of the PSC
                 Group, as the case may be, from the date on which that Perot
                 Supply VAT was incurred to and including the date on which the
                 repayment or credit is obtained.  The interest shall accrue
                 from day to day at the PSC Interest Rate (as defined in the
                 SBC Warburg EPI Agreement), minus any interest paid by the
                 relevant authority in connection with the repayment or credit.

         (c)     For purposes of this Section 10.4, "European VAT" means value
                 added tax as provided for in the Value Added Tax Act 1994 (as
                 amended or re-enacted from time to time, the "Act") and
                 legislation supplemental thereto and any other tax (whether
                 imposed in the United Kingdom in substitution thereof or in
                 addition





                                       33
<PAGE>   34
                 thereto or elsewhere) of a similar fiscal nature, and (except
                 as a result of the gross negligence or willful misconduct of a
                 member of the PSC Group) includes a reference to all fines,
                 penalties, surcharges and interest which may be assessed,
                 levied, charged or imposed pursuant to the Act and/or relevant
                 legislation.

10.5     Indemnification Procedures.  With respect to third-party claims
         subject to the indemnities set forth in this Article X, the indemnitee
         will notify the indemnitor promptly of any matters in respect of which
         the foregoing indemnities may apply and of which the indemnitee has
         knowledge and will give the indemnitor full opportunity to control the
         response thereto and the defense thereof, including, without
         limitation, any agreement relating to the settlement thereof, provided
         that the indemnitee will have the right to approve any settlement or
         any decision not to defend.  The indemnitee's failure to promptly give
         notice will affect the indemnitor's obligation to indemnify the
         indemnitee only to the extent that the indemnitor's rights are
         prejudiced thereby.  The indemnitee may participate, at its own
         expense, in any defense and any settlement directly or through counsel
         of its choice.  If the indemnitor elects not to defend, the indemnitee
         will have the right to defend or settle the claim as it may deem
         appropriate, at the cost and expense of the indemnitor, which will
         promptly reimburse the indemnitee for all such costs, expenses and
         settlement amounts.

10.6     Consequential and Punitive Damages.  In no event will either
         Contracting Party be liable to the other under this Agreement or under
         any EPI Agreement for indirect, incidental, consequential, reliance or
         punitive damages, including, without limitation, damages for lost
         profits (other than, to the extent recoverable under New York law in
         appropriate judicial, arbitration or other legal proceedings, the lost
         profits of any PSC Entity under this Agreement or any EPI Agreement,
         provided, that the amount of any recovery for such lost profits shall
         be deemed to be included within the scope of the maximum liability of
         the SBC Group referred to in Section 10.7(ii)(B) hereof) or injury to
         property or reputation regardless of the form of action, whether in
         contract, indemnity, warranty, strict liability or tort (including
         negligence) and regardless of whether such party has reason to know or
         in fact knows of the possibility thereof.

10.7     Definition of Liability.  All PSC Entities, in the aggregate, and all
         SBC Entities, in the aggregate, will only be liable to the other under
         this Agreement or any EPI Agreement for direct damages that arise
         from:

         (a)     its gross negligence or willful misconduct and that for all
                 events, acts or omissions do not exceed, in the aggregate for
                 this Agreement and all EPI Agreements and for all PSC
                 Entities, $75,000,000, and for all SBC Entities, $75,000,000;
                 provided, that the amount of any recovery for gross negligence
                 or willful misconduct by any SBC Entity shall be deemed to be
                 included within the scope of the maximum liability of the SBC
                 Group referred to in Section 10.7(ii)(B); provided, further,
                 however, if at any time the PSC Entities have paid damages to
                 the SBC Entities aggregating at least $65,000,000, then PSC
                 Parent will have the option, within thirty (30) days of such
                 time, to provide written notice to SBC Parent that PSC Parent
                 has increased the





                                       34
<PAGE>   35
                 aggregate limitation under this Section 10.7(a) by an amount
                 equal to the amount required to increase the aggregate
                 available liability amount back to $75,000,000.  If PSC Parent
                 does not so increase the liability amount, SBC Parent will
                 have ninety (90) days to provide PSC Parent with written
                 notice that this Agreement and each EPI Agreement will
                 automatically terminate unless PSC Parent agrees, in writing,
                 to increase, and does so increase, the liability amount as
                 described above within fifteen (15) days of such written
                 notice.  The procedure described above will be repeated each
                 time the aggregate remaining liability amount under this
                 Section 10.7(a) decreases to less than $10,000,000; and

         (b)     its negligence and that for all events, acts or omissions do
                 not exceed (i) the amount of insurance coverage maintained by
                 the liable SBC or PSC Entity, as the case may be, less (ii)
                 any amounts payable by that liable SBC or PSC Entity, as the
                 case may be, pursuant to Section 10.7(a) above; provided that
                 no amount will be due or payable to either the members of the
                 PSC Group or the members of the SBC Group, as the case may be,
                 under this Section 10.7(b) unless and until the liable party
                 is finally paid that amount by its insurance carrier.  In the
                 event of any dispute between a SBC Entity and a PSC Entity
                 that is likely to give rise to a claim that would be subject
                 to the provisions of this Section 10.7(b), the liable party
                 will upon request of the other party exercise good faith  in
                 determining whether and when to notify  its insurance carrier
                 of the claim in order to preserve its ability to collect under
                 the applicable insurance policies with respect to that claim
                 and will comply with the claim handling procedures specified
                 by its applicable insurance policies.

         The limitations set forth in this Section 10.7 will not apply (i) with
         respect to either the members of the SBC Group or of the PSC Group to
         the indemnity obligations under Section 10.2 hereof or the indemnity
         obligations under Section 10.1 hereof that relate to personal injury,
         and (ii) with respect to the members of the SBC Group, to (A) amounts
         payable by the members of the SBC Group to the members of the PSC
         Group for Services that have been provided under any EPI Agreement,
         and (B) in the event of a breach or termination of this Agreement or
         any EPI Agreement, direct damages recoverable under New York law and
         any recoverable lost profits under New York law of any PSC Entity
         under this Agreement or any EPI Agreement in respect of such breach or
         termination, but in no event will the members of the SBC Group be
         liable for any amounts described in this Section 10.7(ii)(B), which
         exceed, in the aggregate for all such breaches and terminations under
         this Agreement and all EPI Agreements for all members of the SBC
         Group, $250,000,000 plus one-half (1/2) of the Shares Termination
         Value, plus all amounts recoverable under Section 10.7(ii)(A) hereof.

10.8     Disclaimer of Warranties.  EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN
         AN EPI AGREEMENT, NEITHER ANY MEMBER OF THE PSC GROUP NOR ANY MEMBER
         OF THE SBC GROUP MAKES ANY, AND EACH SUCH MEMBER HEREBY DISCLAIMS ALL,
         WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTIES OF
         MERCHANTIBILITY OR FITNESS FOR A PARTICULAR PURPOSE RELATING TO ANY
         GOODS OR SERVICES PROVIDED PURSUANT TO THIS AGREEMENT OR ANY EPI
         AGREEMENT.

10.9     Risk of Loss.  Subject to Section 10.7 hereof, during the term of each
         EPI Agreement, the risk of loss for Equipment and Systems provided in
         accordance with Article IV hereof or otherwise pursuant to any EPI
         Agreement will remain with the owner of the applicable Equipment or
         System.

                                 MISCELLANEOUS

11.1     Original Agreement.  SBC Parent and PSC Parent each acknowledge and
         agree that, notwithstanding anything to the contrary contained herein,
         the terms of the Original Agreement will govern PSC Parent's and SBC
         Parent's respective obligations thereunder with regard to any matters
         that occurred prior to the Adjustment Date.

11.2     Binding Nature and Assignment.  This Agreement and each EPI Agreement
         will be binding on the applicable Contracting Party and their
         respective successors and assigns, but no Contracting Party may, or
         will have the power to, assign this Agreement without the prior
         written consent of the other Contracting Party, except that the
         applicable SBC Entity may assign those portions of an EPI Agreement
         (including to an SBC Entity) necessary to comply with, and to the
         extent required by, Section 2.4(b) hereof.

11.3     Hiring of Employees.  Except as otherwise expressly provided herein,
         each Contracting Party agrees that, during the term of the EPI
         Agreement to which it is a party and for two (2) years thereafter,
         neither it nor any of its Affiliates may, except with the prior
         written consent of the other, offer employment to or employ any person
         employed then or within the preceding twelve (12) months by the other
         or any Affiliate of the other.

11.4     Notices.  Whenever under this Agreement one party is required or

         new address and the date upon which it will become effective.

11.5     Counterparts.  This Agreement may be executed in several counterparts,
         all of which taken together constitute one single agreement between
         the Contracting Parties hereto and each EPI Agreement may be executed
         in several counterparts, all of which taken together will constitute
         one single agreement between the Contracting Parties thereto.

11.6     Headings.  The article and section headings used herein and in each
         EPI Agreement are for reference and convenience only and will not
         enter into the interpretation hereof and thereof.

11.7     Relationship of Parties.  Each PSC Entity, in furnishing services to
         each SBC Entity hereunder or under any EPI Agreement, is acting only
         as an independent contractor.  No PSC Entity undertakes by this
         Agreement or any EPI Agreement or otherwise to perform any obligation
         of any SBC Entity, whether regulatory or contractual (excluding the
         Third Party Service Contracts), or to assume any responsibility for
         any SBC Entity's business or operations.  Each PSC Entity has the sole
         right and obligation to supervise, manage, contract, direct, procure,
         perform or cause to be performed, all work to be performed by that PSC
         Entity under the applicable EPI Agreement, unless otherwise provided
         therein.

11.8     Approvals and Similar Actions.  Where agreement, approval, acceptance,
         consent or similar action by any Contracting Party to this Agreement
         or any EPI Agreement is required by any provision of this Agreement or
         that EPI Agreement (except with respect to the Security





                                       37
<PAGE>   38
         Procedures), such action will not be unreasonably delayed or withheld.
         Each member of the PSC Group will be relieved of its obligation to
         perform any Service or meet any Service Level to the extent that the
         ability of such member of the PSC Group to perform those obligations
         under this Agreement or any EPI Agreement is adversely affected by any
         member of the SBC Group unreasonably withholding or delaying any
         agreement, approval, consent or similar action on account of or with
         respect to the Security Procedures, and each member of the SBC Group
         hereby waives any right to terminate, or claim a breach of or default
         under, this Agreement or any EPI Agreement on account of or with
         respect to any failure by the applicable member of the PSC Group to so
         perform.

11.9     Media Releases.  All media releases, public announcements and public
         disclosures by any member of the SBC Group or any member of the PSC
         Group relating to this Agreement or the transactions contemplated
         hereby, including, without limitation, promotional or marketing
         material (but not including any announcement intended solely for
         internal distribution within the SBC Group or the PSC Group, as the
         case may be, or any disclosure required by legal, accounting or
         regulatory requirements beyond the reasonable control of any member of
         the SBC Group or the PSC Group, as the case may be, to the extent the
         timing of any such disclosure reasonably prevents any coordination
         with the other party) will be coordinated with and approved by the
         other prior to the release thereof.

11.10    Force Majeure.  Each Contracting Party will be excused from
         performance hereunder and under any EPI Agreement for any period and
         to the extent that it is prevented from performing, in whole or in
         part, under this Agreement and under any EPI Agreement as a result of
         delays caused by the other party or an act of God, war, civil
         disturbance, court order, governmental actions, adverse weather
         condition, labor dispute, third party nonperformance, or other cause
         beyond its reasonable control, including failures or fluctuations in
         electrical power, heat, light, or air conditioning, and such
         nonperformance will not be a default hereunder or under any EPI
         Agreement or grounds for termination hereof or thereof.  If a PSC
         Entity suspends performance of the Services under any EPI Agreement
         pursuant to this Section 11.10 for a period of time greater than two
         (2) consecutive days or four (4) days within any thirty (30) day
         period for any reason, (a) the applicable SBC Entity's payment
         obligations with respect to that portion of the Services that the
         applicable PSC Entity has suspended performance of pursuant to this
         Section 11.10 will also be suspended for an identical period of time,
         (b) the applicable PSC Entity, or if that PSC Entity is unwilling or
         unable, the applicable SBC Entity, may contract with a third party to
         provide services in substitution of the suspended Services for the
         period of the suspension, it being agreed that the applicable SBC
         Entity will not be obligated to compensate that PSC Entity for
         services that have been provided by a member of the SBC Group or such
         third party during that period of suspension, except as otherwise
         specifically provided in the EPI Agreement, and (c) the applicable
         Contracting Parties agree to use commercially reasonable efforts and
         to cooperate in good faith to resolve any issue that arises in
         connection with a suspension of the provision of Services by the
         applicable PSC Entity in accordance with this Section 11.10.

11.11    Severability.  If any provision of this Agreement or any EPI Agreement
         is declared or found to be illegal, unenforceable or void, then the
         applicable Contracting Parties will be relieved of all obligations
         arising under such provision, but only to the extent that such
         provision is illegal, unenforceable or void, it being the intent and
         agreement of the parties that this Agreement and any applicable EPI
         Agreement will be deemed amended by modifying such provision to the
         extent necessary to make it legal and enforceable while preserving the
         economic benefits of each party or, if that is not possible, by
         substituting therefor another provision that is legal and enforceable
         and achieves the same objective.  If the remainder of this Agreement
         and any applicable EPI Agreement will not be affected by such
         declaration or finding and is capable of substantial performance in a
         manner that would preserve each party's economic benefit, then each
         provision not so affected will be enforced to the extent permitted by
         law.

11.12    Waiver.  No delay or omission by any Contracting Party hereto or to
         any EPI Agreement to exercise any right or power hereunder or
         thereunder will impair such right or power or be construed to be a
         waiver thereof.  A waiver by any Contracting Party hereto or to any
         EPI Agreement of any of the covenants to be performed by the other or
         any breach thereof will not be construed to be a waiver of any
         succeeding breach thereof or of any other covenant herein or therein
         contained.  Except as otherwise provided in this Agreement or any EPI
         Agreement, all remedies provided for in this Agreement and any EPI
         Agreement will be cumulative (with respect to either this Agreement or
         that EPI Agreement) and in addition to and not in lieu of any other
         remedies available to either party at law, in equity or otherwise.

11.13    Attorneys' Fees.  If any legal action or other proceeding is brought
         for the enforcement of this Agreement or any EPI Agreement, or because
         of an alleged dispute, breach, default or misrepresentation in
         connection with any of the provisions of this Agreement or any EPI
         Agreement, the prevailing party will be entitled to recover reasonable
         attorneys' fees and other costs incurred in that action or proceeding,
         in addition to any other relief to which it may be entitled.

11.14    Entire Agreement.  Except as set forth in the Principal Agreements,
         (as defined in the Master Agreement) this Agreement, including any
         Schedules and agreements referred to herein and attached hereto, each
         of which is incorporated herein for all purposes, constitutes,
         together with any other written agreement or letter between SBC and
         PSC dated the Adjustment Date or as of the Adjustment Date, or the
         Original Agreement Date or as of the Original Agreement Date (not
         including agreements or letters amended,  restated or superseded as of
         the Adjustment Date), that relates to this Agreement, the entire
         agreement between the parties hereto with respect to the subject
         matter hereof and there are no representations, understandings or
         agreements, written or oral, relative hereto which are not fully
         expressed herein.  No change, waiver or discharge hereof will be valid
         unless in writing and signed by an authorized representative of the
         party against which such change, waiver, or discharge is sought to be
         enforced.

11.15    Governing Law.  This Agreement and each EPI Agreement will be governed
         by and construed in accordance with the laws, other than choice of law
         rules, of the State of New





                                       39

         York; provided, however, that to the extent any claim or cause of
         action is based upon a violation of the Security Procedures, such
         claim or cause of action will be governed by the laws of the
         jurisdiction whose bank secrecy laws are alleged to have been
         violated.

11.16    Venue.  Any arbitration proceeding regarding any dispute arising under
         or related to this Agreement will take place in New York as described
         in Section 7.4 hereof.  Any judicial proceeding, referenced in Section
         7.5 hereof, regarding any dispute arising under or related to this
         Agreement or any EPI Agreement will be brought exclusively in the
         courts of the State of New York, or in the United States District
         Court for the Southern District of New York, and each party hereto
         submits to the personal jurisdiction of such courts and hereby
         irrevocably agrees to be bound by any judgment rendered thereby in
         connection with this Agreement or any EPI Agreement and waives any
         claim or defense that party may have based on a lack of personal
         jurisdiction or the doctrine of forum non conveniens.  Notwithstanding
         the foregoing, if any claim or cause of action seeking non-monetary
         injunctive relief (and excluding damages) is brought regarding the
         violation of the Security Procedures, such claim or cause of action
         will be brought exclusively in the courts of Switzerland, and each
         party hereto submits to the personal jurisdiction of such courts and
         hereby irrevocably agrees to be bound by any judgment rendered thereby
         in connection with this Agreement or any EPI Agreement and waives any
         claim or defense that party may have based on a lack of personal
         jurisdiction or the doctrine of forum non conveniens.

11.17    Survival.  The provisions of Sections 4.1, 4.2, 4.3, 8.10 and 11.3,
         and Articles IX and X shall survive any termination of this Agreement
         or any EPI Agreement and the consummation of the transactions
         contemplated hereby or thereby.

11.18    Expenses.  Except as otherwise provided in this Agreement, each of SBC
         and PSC will pay all of its own expenses relating to the negotiation,
         execution and delivery of this Agreement (excluding any amendments,
         modifications or supplements hereto), including without limitation,
         the fees and expenses of its counsel, financial advisors and
         accountants.

IN WITNESS WHEREOF, PSC Parent and SBC Parent have each caused this Agreement
to be signed and delivered by its duly authorized officer(s), all as of the
Adjustment Date.

                                   SCHEDULE A

                                ESCROW OF SHARES


If any EPI Agreement (the "Terminated EPI Agreement") is terminated by an SBC
Contracting Party pursuant to Sections 8.1, 8.4, 8.5, 8.6 or 8.9 of this
Agreement, then in order to secure the payment to any member of the SBC Group
by any member of the PSC Group of any damages for which that member of the PSC
Group is liable hereunder as a result of  the failure by that member of the PSC
Group to perform its termination assistance obligations pursuant to this
Agreement or the applicable EPI Agreement:

1.       PSC Parent will deposit into escrow a number of shares of Class A
         Stock (the "Escrow Shares") equal to 90% (or, if the Terminated EPI
         Agreement is the SBC Warburg EPI Agreement, 95%) of the number of
         additional shares of Class B common stock, par value $.01 per share of
         PSC (the "Class B Stock"), for which the options  warrants or similar
         rights (if any) would have become or remained  exercisable under the
         Terminated EPI Agreement had the Terminated EPI Agreement not been
         terminated and instead remained in effect for its full stated term
         plus the number of shares of Class B Stock that would have become
         vested (if any) under the Terminated EPI Agreement had the Terminated
         EPI Agreement not been terminated and instead remained in effect for
         its full stated term.

2.       If the Fair Market Value (as defined in paragraph 5 below) of the
         Escrow Shares does not equal or exceed $50,000,000 and, prior to the
         termination date of the Terminated EPI Agreement, Class A Shares have
         been Publicly Traded, then PSC Parent will:

         (a)     Deposit into the escrow an amount either by deposit of cash,
                 additional Class A Shares or other valuables, with a value
                 (which, in the case of any such Class A Shares, will equal
                 Fair Market Value) up to the difference between the Fair
                 Market Value of the Escrow Shares and $50,000,000; and

         (b)     Provide other security in the form of a bond, guaranty or
                 other form of assurance reasonably acceptable to SBC Parent in
                 an amount equal to the difference between the Fair Market
                 Value of the Escrow Shares and $50,000,000 (less the value of
                 the property placed in escrow under paragraph (2)(a) above).

3.       Notwithstanding anything to the contrary above, the Fair Market Value
         of all the Escrow Shares, plus the value of the cash and other assets
         placed in escrow by PSC Parent pursuant to Section 2(a) above and the
         amount of other security and assurances provided by PSC Parent
         pursuant to Section 2(b) above, with respect to all EPI Agreements,
         may never exceed, in the aggregate, $50,000,000 (valued on the date of
         deposit into escrow).

4.       The Escrow Shares and other amounts held in escrow and any other
         security and assurances provided by PSC Parent (collectively, the
         "Security") will be released in accordance with the following:





                                       A-1
<PAGE>   42
         (a)     The applicable PSC Contracting Party will notify the
                 applicable SBC Contracting Party when that PSC Contracting
                 Party believes it has performed the termination assistance
                 services that it was obligated to perform within the first 18
                 months after termination of the Terminated EPI Agreement (the
                 "Required Termination Assistance").

         (b)     If that SBC Contracting Party agrees that the applicable PSC
                 Contracting Party did so perform the Required Termination
                 Assistance, or if that SBC Contracting Party  fails to notify
                 the applicable PSC Contracting Party of any deficiency in its
                 performance of the Required Termination Assistance within ten
                 days after receiving notification from that PSC Contracting
                 Party pursuant to Section 4(a) above, the Security, including
                 any interest thereon, will be released to PSC Parent.

         (c)     If that SBC Contracting Party does not agree that the
                 applicable PSC Contracting Party has performed the Required
                 Termination Assistance, that SBC Contracting Party will
                 provide the PSC Contracting Party with written notice
                 specifying the services that the SBC Contracting Party
                 believes the applicable PSC Contracting Party was obligated
                 to, and did not, perform, and provide that PSC Contracting
                 Party with ten working days to cure the failure to perform. If
                 that PSC Contracting Party has not cured the default within
                 the ten working day cure period, then the parties will submit
                 the dispute to arbitration in accordance with Section 7.4 of
                 this Agreement.

         (d)     The arbitration panel will be directed by each party to first
                 determine the maximum amount of damages that the PSC
                 Contracting Party can reasonably expect to be liable for as a
                 result of those services that the applicable SBC Contracting
                 Party reasonably claims the PSC Contracting Party has failed
                 to perform.  The difference, if any, between that amount and
                 the total value of the Security, including any interest
                 thereon, will be released to PSC Parent.  The remainder of the
                 Security will be retained in the escrow until such time as the
                 arbitration panel reaches a resolution, at which point the
                 remainder of the Security, including any interest thereon,
                 will be allocated between the PSC Group and the SBC Group as
                 the arbitration panel determines; provided that the Class A
                 Shares may only be released from escrow for sale by SBC to the
                 extent such release and sale are permissible under the Bank
                 Holding Company Act of 1956, as amended.

5.       For purposes of this Schedule A:

         (a)     "Average Market Value" means the average of the Closing Price
                 for the security in question for the thirty (30) Trading Days
                 immediately preceding the date of termination of the
                 Terminated EPI Agreement.

         (b)     "Closing Price" means, as to any security:





                                       A-2
<PAGE>   43
                 (1)      If the primary market for the security in question is
                          a national securities exchange registered under the
                          Securities Exchange Act of 1934, as amended, the
                          Nasdaq National Market or another market or quotation
                          system in which last sale transactions are reported
                          on a contemporaneous basis, the last reported sales
                          price, regular way, of such security for such day,
                          or, if there has not been a sale on such Trading Day,
                          the highest closing or last bid quotation therefor on
                          such Trading Day (excluding, in any case, any price
                          that is not the result of bona fide arm's length
                          trading); or

                 (2)      If the primary market for such security is not an
                          exchange or quotation system in which last sale
                          transactions are contemporaneously reported, the
                          highest closing or last bona fide bid or asked
                          quotation by disinterested Persons in the
                          over-the-counter market on such Trading Day as
                          reported by the National Association of Securities
                          Dealers through its Automated Quotation System or its
                          successor or such other generally accepted source of
                          publicly reported bid quotations as SBC and PSC
                          designate.

         (c)     "Fair Market Value" means:

                 (1)      As to securities regularly traded in the organized
                          securities markets, the Average Market Value; and

                 (2)      As to all securities not regularly traded in the
                          securities markets, the fair market value of such
                          securities as determined as set forth below.  For a
                          period of thirty (30) days after the termination date
                          of the Terminated EPI Agreement (the "Negotiation
                          Period"), PSC and SBC each agrees to negotiate in
                          good faith to reach agreement upon the fair market
                          value of such securities, as of the termination date
                          of the Terminated EPI Agreement. In the event that
                          the parties are unable to agree upon the fair market
                          value of such securities by the end of the
                          Negotiation Period, then the fair market value of
                          such securities will be determined for purposes of
                          this Schedule A by an independent appraiser mutually
                          acceptable to SBC and PSC (the "Appraiser") whose
                          appraisal will be conclusive and binding on the
                          parties.  For such purposes, fair market value will
                          be calculated without premium for control or discount
                          for minority interests, illiquidity, or restrictions
                          on transfer.  The costs of the Appraiser will be
                          borne by SBC and PSC equally.

         (d)     "Trading Day" means any business day in which the securities
                 in question are tradeable on stock exchanges, in the
                 over-the-counter markets or otherwise.

                                   WITNESSETH

WHEREAS, SBC and PSC entered into the Agreement for Operational Management

WHEREAS, SBC and PSC now desire to amend and restate the Original Agreement to

4.       Term.  The term of this EPI Agreement will commence on the Adjustment
         Date and, unless earlier terminated in accordance with the terms of
         the Master Operating Agreement, will continue until the tenth (10th)
         anniversary of the Adjustment Date or such later date as the parties
         may mutually agree.

5.       PSC Obligations and Performance Metrics.  During the term of this EPI
         Agreement:

         (a)     PSC will make available to the SBC Warburg Division, for the
                 SBC Warburg Division's use in accordance with Article IV of
                 the Master Operating Agreement, any PSC Systems used by PSC in
                 the Operational Management of the EPI of the SBC Warburg
                 Division.

         (b)     PSC will provide the Services (including making available in a
                 timely fashion qualified people to perform, and to respond to
                 SBC's reasonable requests for, Services) (i) contemplated by
                 the PSC Costs Budget or Equipment and Facilities Budget (as
                 each such term is defined in Schedule F hereto) and, where
                 applicable, will use reasonable efforts to meet any Service
                 Levels mutually established for those Services  or (ii) for
                 which SBC agrees to otherwise pay PSC in accordance with
                 Schedule F hereto.  Additionally, and notwithstanding anything
                 else in this EPI Agreement to the contrary, SBC will pay PSC
                 in accordance with Schedule F, including the quarterly
                 adjustment provisions thereof, for any Services required to be
                 provided and which are provided by PSC to the SBC Warburg
                 Division whether the amounts for those Services are or are not
                 included in a PSC Costs Budget.  Subject to the foregoing, PSC
                 agrees that it will abide by any cost approval processes of
                 which PSC may receive notice from SBC from time to time,
                 including the SBC Warburg Central Approval and Order Process,
                 within a reasonable period of time after receipt thereof.

         (c)     The Performance Metrics will be established as follows:

                 (1)      During a period of at least thirty (30) days prior to
                          the end of each  Budget Period, PSC and SBC will work
                          together in good faith to establish the Performance
                          Metrics that will apply to the following Budget
                          Period.

                 (2)      In connection with the establishment of the
                          Performance Metrics, a weighted percentage will be
                          assigned to each Performance Metric in order to
                          calculate any "penalties" or "rewards" as described
                          in Schedule G hereto.





                                      3
<PAGE>   4



                 (3)      The Performance Metrics and weighted percentages will
                          all be established and adjusted from time to time
                          such that, after taking into account all "penalties"
                          and "rewards", if PSC's actual level of performance
                          meets the anticipated typical or median (neither
                          superior nor inferior) performance expected by the
                          parties, it is expected that PSC will be paid an
                          amount equal to the Annual Profit Amount (as defined
                          in Schedule F hereto).

                 (4)      If SBC and PSC are unable to agree on the Performance
                          Metrics at least thirty (30) days prior to the
                          beginning of any particular Budget Period, (i) the
                          Performance Metrics that PSC and SBC have agreed will
                          apply for the prior  Budget Period will remain in
                          effect until replaced by any new mutually agreed upon
                          Performance Metrics, and (ii) the determination of
                          the appropriate "rewards" and "penalties" will be
                          made, and payments made or credits applied on a
                          quarterly, rather than annual, basis within twenty
                          one (21) days after the end of each quarter  of the
                          Budget Period until such time as such Performance
                          Metrics are replaced with new mutually agreed upon
                          Performance Metrics.

                 (5)      On or before December 15 of each Budget Period, PSC
                          will deliver to the SBC Operational Manager in
                          writing its estimate of the total PSC Costs for the
                          current Budget Period.  Within seven (7) days
                          thereafter, the SBC Operational Manager and the PSC
                          Relationship Manager will meet at a mutually agreed
                          time to discuss SBC's good faith estimate of the
                          Annual Profit Amount, as adjusted by the aggregate
                          Penalty Percentages or Reward Percentages, as
                          applicable, for such Budget Period.  Thereafter, PSC
                          will deliver to SBC its final invoice for the Budget
                          Period and within seven (7) days of receipt thereof
                          SBC will deliver its final determination of the
                          Annual Profit Amount, as adjusted in accordance with
                          Schedule G.  If PSC's estimate of the total PSC Costs
                          for the Budget Period is in excess by less than Five
                          Million Dollars ($5,000,000) of the actual total PSC
                          Costs for the Budget Period invoiced, then SBC's good
                          faith estimate of the Annual Profit Amount, as
                          adjusted, may only be adjusted down by a Penalty
                          Percentage of a maximum of five and one-half percent
                          (5.5%) of the Annual Profit Amount.  If, however,
                          PSC's good faith estimate of the total PSC Costs for
                          the Budget Period is in excess of Five Million
                          Dollars ($5,000,000) over the actual total PSC Costs
                          for the Budget Period, then SBC may adjust the Annual
                          Profit Amount otherwise in accordance with Schedule G
                          without restriction as imposed by this Section
                          5(c)(5).

                 (6)      If there is any dispute over the establishment of the
                          Performance Metrics or related rewards and penalties
                          and the dispute falls within the procedures described
                          in Section 7.3 of





                                      4
<PAGE>   5



                          the Master Operating Agreement, the dispute will be
                          escalated to the Chairman of PSC and the CEO of SBC.

                 (7)      Upon the request of the PSC CEO no more frequently
                          than once per calendar quarter, the SBC Operational
                          Manager will provide the PSC CEO with a good faith
                          outlook with respect to PSC performance on the
                          Performance Metrics for the remainder of the
                          then-current Budget Period.

         (d)     As PSC and SBC establish unit prices for each mutually
                 identified measurable unit of the Services, PSC and SBC will
                 also establish appropriate performance metrics with related
                 bonuses and credits and will adjust the Annual Profit Amount
                 (as defined in Schedule F hereto) and the Performance Metrics
                 and related bonuses and credits, all to reflect the conversion
                 of certain of the Services from a cost- reimbursement basis to
                 a fixed-unit price basis.

         (e)     Subject to the terms and conditions of this EPI Agreement,
                 including without limitation Section 8 hereof, if PSC does not
                 meet any Performance Metric applicable to the Services, then
                 as PSC's sole obligation and SBC's sole remedy, PSC's charges
                 to SBC will be adjusted in accordance with Schedule G hereto.
                 In no event will PSC be liable for failing to meet Performance
                 Metrics during any year of the term of this EPI Agreement if
                 and to the extent that any such failure arose as a result of
                 (i) any request by an SBC Warburg Division Member for PSC to
                 reduce the resources or Services that PSC is then providing
                 hereunder, (ii) any action taken by SBC in contravention of
                 the terms of this EPI Agreement or (iii) any reduction by SBC
                 of the PSC Costs Budget or the Equipment and Facilities Budget
                 (as each term is defined in Schedule F hereto).  In the event
                 of (i), (ii), or (iii) above, PSC and SBC will work together
                 in good faith to renegotiate the affected Performance Metrics.

         (f)     PSC will timely provide SBC with a quarterly performance
                 report, in a form and with content mutually established by the
                 parties, documenting PSC's performance with respect to the
                 Performance Metrics.

         (g)     It is PSC's intention to use the SBC Warburg Infrastructure
                 and the Transitioned Employees in order to provide services to
                 other PSC customers, subject to the security and
                 confidentiality provisions of the Master Operating Agreement
                 and this EPI Agreement.  Prior to any use of the SBC Warburg
                 Infrastructure in connection with the provision of services to
                 a third party by PSC, PSC must comply with the provisions of
                 Section 6 of Appendix 1 to Schedule F hereto.  Nothing in this
                 EPI Agreement will limit PSC's rights to use the Licensed SBC
                 Systems in accordance with the Master Operating Agreement.

         (h)     With respect to those PSC employees that have a significant,
                 direct working relationship with the SBC Warburg Division
                 business units, SBC will provide to PSC specific criteria for
                 the  comprehensive incentive based compensation program
                 established for those PSC





                                      5
<PAGE>   6



                 employees that will be designed to reward those employees for
                 performance that, while not disadvantaging PSC, directly
                 benefits those areas of SBC's business deemed important to
                 SBC.  During PSC's annual review of those PSC employees, SBC
                 will provide PSC with SBC's assessment of those PSC employees
                 based upon the specific criteria provided by SBC.
                 Notwithstanding the foregoing, PSC retains ultimate control
                 over the compensation of its employees.

         (i)     PSC will also have responsibility for the functions and
                 obligations set forth on Schedule D hereto.

         (j)     PSC will use all reasonable efforts to maintain an errors and
                 omissions insurance policy with one hundred million dollars
                 ($100,000,000) of coverage and the cost of the policy will be
                 a direct PSC Cost.  Other policies of insurance maintained by
                 PSC with coverage above the coverage maintained by PSC prior
                 to the Original Agreement Date, up to an aggregate of
                 seventy-five million dollars ($75,000,000) in coverage, will
                 be a direct PSC Cost until the time that those other policies
                 of insurance can be used by PSC to insure against risks
                 incurred by PSC as a result of its relationships with other
                 customers of PSC, at which time the costs of that insurance
                 will be allocated among all PSC accounts for which such
                 insurance can be used in accordance with the amount of
                 insurance coverage that can be used with respect to such
                 customer.  SBC and PSC will periodically determine whether
                 these limits should be adjusted to take into account the
                 effects of inflation.

6.       SBC Obligations.  Commencing on the Original Agreement Date:

         (a)     SBC has and will continue to make available to PSC, for PSC's
                 use in accordance with Article IV of the Master Operating
                 Agreement, the SBC Warburg Infrastructure.  Other than as sold
                 or terminated in the ordinary course of business with the
                 consent of both parties prior to the date of delivery of this
                 Agreement, SBC represents to PSC that the SBC Warburg
                 Infrastructure made available to PSC hereunder includes all of
                 the Equipment, SBC Systems, SBC Facilities and services from
                 Third Party Service Contracts used by or on behalf of the SBC
                 Warburg Division as of the Original Agreement Date to provide
                 the Services to the SBC Warburg Division that PSC is obligated
                 to provide under this EPI Agreement.

         (b)     Except as expressly permitted by this EPI Agreement, the
                 Master Agreement (herein so called), executed by SBC and PSC
                 as of the Adjustment Date, or the Master Operating Agreement,
                 neither SBC nor the SBC Warburg Division Members will enter
                 into any agreements with third parties relating to any
                 products or services for which PSC has responsibility
                 hereunder.  SBC agrees that it will not enter into any Third
                 Party Service Contracts for services relating to the
                 Operational Management of the EPI of the SBC Warburg Division
                 during the term of this EPI Agreement, except as otherwise
                 approved by PSC or authorized by the terms of this EPI
                 Agreement.





                                      6

         (c)     SBC will retain responsibility for the functions and
                 obligations set forth on Schedule C hereto.

         (d)     SBC will use all commercially reasonable efforts to cause the
                 SBC Warburg Division to standardize the products and services
                 for which PSC has responsibility hereunder within the SBC
                 Warburg Division as soon as reasonably practicable.

         of SBC (as defined in the Master Operating Agreement) for SBC will be
         David Solo, Peter Wuffli, or another individual satisfactory to the
         Operational Manager of PSC; provided that should PSC not consent to
         the designation of any Operational Manager designated pursuant to the
         Master Operating Agreement other than David Solo or Peter Wuffli, then
         the following shall apply:  The matter of who shall serve as the
         Operational Manager for SBC under this EPI Agreement will be referred

         CEO's.  In the event that the CEO's do not agree on the individual who
         shall serve as the Operational Manager for SBC, then for the first
         twelve (12) months during which such disagreement as to the
         Operational Manager for SBC continues, PSC shall be deemed to have
         performed under the terms of this EPI Agreement each of the
         Performance Metrics to the extent necessary so that there is no Reward
         Percentage or Penalty Percentage applied under Schedule G of this EPI
         Agreement, and PSC will be entitled to receive the Annual Profit
         Amount on a pro rata basis for each of such twelve (12) months without

         so long as such disagreement continues, and notwithstanding Schedule G
         hereto, the Reward Pool will be an amount equal to seven and one half
         percent (7.5%) of the Annual Profit Amount and the Penalty Pool will
         be an amount equal to fifteen percent (15%) of the Annual Profit
         Amount.

                                   SCHEDULE A

                                  PSC SERVICES

The Services included within the Scope of Services collectively make up  data
processing services  and specifically center on the support of: the entire wide
and local area communication network software and hardware; all data centers
and network, file and data servers; all desktop computer support, office
automation tools (specifically global email design, operation and support), the
work to ensure global connectivity and relatively free-seating capability;
customer help desk for non application specific problems; design, staging,
installation and restacking of an appropriate range of workstation offerings
(fixed and portable); design and support expertise for the inevitably evolving
standards of institutional process automation infrastructure (such as Internet
standards and Web technology).

The Scope of Services does not include services required for the design or
implementation of software packages ("Excluded Software Packages") for
transaction processing, custody, settlement/payments services, pricing tools,
risk control, customer MIS, financial reporting, general ledgers, payment
systems or other applications or business systems.  However, the Scope of
Services does include the Services necessary for operating the systems that run
the Excluded Software Packages, to include appropriate monitoring of task
completion, etc.  PSC will, within the Scope of Services, facilitate the normal
restack and periodic site relocation (to include the Stamford and Stardust work
contemplated as of the Adjustment Date), though a major relocation project
(excluding the currently configured Stamford and Stardust moves) or the support
of a new geographic officewould be outside the Scope of Services and require
additional compensation as described in Schedule F to this EPI Agreement.
Likewise, if there is a substantial increase in the services necessary to
support the SBC Warburg Division, other than the SBC Private Banking Division
outside of Switzerland and the SBC Brinson Division outside of Chicago,  as
requested by SBC (for example, such as an increase of more than 7% during any
Budget Period or 35% in the aggregate in the number of workstations (not
bandwidth) currently supported by PSC), or (ii) if the services are required to
support the SBC Private Banking Division in Switzerland or the SBC Brinson
Division in Chicago then these additional services would be outside the Scope
of Services and require additional compensation as described in Schedule F to
this EPI Agreement.

         (b)     "Cost Plus Service" means all Services provided by PSC

                 similarly situated with PSC could not reasonably be expected
                 to incur in performing the Services.  Such written notice will
                 set forth the basis for SBC's belief in reasonable detail.

                          amount equal to the PSC Interest Rate on the amount
                          owed by SBC calculated from the date the amount owed
                          by SBC was due and payable until the date it is paid
                          to PSC.

         (g)     "PSC Interest Rate" means the London Interbank Offered Rate as
                 published in the Wall Street Journal (national edition) for
                 three (3) month U.S. Dollar deposits, plus two percent (2%),
                 or if no such rate is quoted, the rate for certificates of
                 deposit of major New York banks as quoted in the Wall Street
                 Journal (national edition) for three (3) month certificates of
                 deposit plus two percent (2%).  PSC and SBC will adjust the
                 PSC Interest Rate for each Budget Period as necessary to
                 reflect changed circumstances.

         (h)     "SBC Interest Payment" means, with respect to any amount
                 overpaid by SBC and reimbursable by PSC to SBC under this EPI
                 Agreement and for which this EPI Agreement expressly provides
                 for an interest payment equal to the SBC Interest Payment, an
                 amount equal to the SBC Interest Rate on the amount
                 reimbursable by PSC calculated from the date the amount
                 reimbursable by PSC was overpaid by SBC until the date it is
                 reimbursed to SBC.

         (i)     "SBC Interest Rate" means the London Interbank Offered Rate as
                 published in the Wall Street Journal (national edition) for
                 three (3) month U.S. Dollar deposits, plus two percent (2%) or
                 if no such rate is quoted, the rate for certificates of
                 deposit of major New York banks as quoted in the Wall Street
                 Journal (national edition) for three (3) month certificates of
                 deposit plus two percent (2%).  PSC and SBC will adjust the
                 SBC Interest Rate for each Budget Period as necessary to
                 reflect changed circumstances.

         (j)     "Special Profit Fee" means a one time payment of Three Million

                 stamp, franchise, business privilege, property, value added,
                 import duties, employment, withholding, payroll, sales, ad

                 or special, ordinary or extraordinary, and any transaction
                 privilege or similar taxes together with any and all
                 penalties, fines, surcharges, additions to tax and interest
                 thereon; but excluding any taxes based on the net income (or
                 gross income, profits or franchise taxes in lieu of or in
                 conjunction with net income) of PSC imposed by any federal,
                 state, provincial, cantonal, local or any similar
                 jurisdiction, and any withholding tax associated with the
                 distribution of that net income (or gross income, profits or
                 franchise taxes in lieu of or in conjunction with net income).

2.       Budget and Capacity Planning.  The PSC Costs Budget and the Equipment
         and Facilities Budget will be established in accordance with Appendix
         1 to this Schedule F.





                                      F-3
<PAGE>   17



3.       Cost Plus Services.  During each Budget Period:

         (a)     PSC's estimated and budgeted charges to SBC for the Cost Plus
                 Services will be an amount equal to (i) the PSC Costs
                 reflected in the PSC Costs Budget for that Budget Period that
                 it is estimated PSC will incur during that Budget Period
                 relating to the Cost Plus Services, plus (ii) the then current
                 Annual Profit Amount.

         (b)     Subject to receipt of an invoice pursuant to Section 6 hereof,
                 on the tenth day (or, if not a business day, the first
                 business day thereafter) of each month during that Budget
                 Period, SBC will pay to PSC, by wire transfer to a bank
                 account designated by PSC, an amount equal to the Monthly Run
                 Rate (as defined in Section 1(b)(3) of Appendix 1 to this
                 Schedule F) applicable to the Cost Plus Services for that
                 month.

         (c)     At the end of each calendar quarter during that Budget Period
                 (or, at the request of either party, more often than quarterly
                 to take into account significant differences between actual
                 PSC Costs and the Monthly Run Rate), PSC will determine the
                 actual PSC Costs and the pro rata portion of the Annual Profit
                 Amount relating to the Cost Plus Services for all prior
                 periods.  To the extent the actual PSC Costs for the Cost Plus
                 Services for prior periods varied from the estimated amounts
                 paid under Section 3(b) with respect to those prior periods
                 and such variance has not been taken into account in
                 connection with prior adjustments under this Section 3(c), PSC
                 will either issue to SBC (i) an invoice for additional amounts
                 owed by SBC, plus the PSC Interest Payment, or (ii) a credit
                 against the next month's invoice for amounts overpaid by SBC
                 as a result of such variances, plus the SBC Interest Payment.

4.       Services Not Within the Scope of  Services.  Upon the occurrence of
         any event or events that would require PSC to provide services outside
         the Scope of Services or development, maintenance or enhancement
         services related to the Restricted Application Systems, SBC will pay
         PSC for the resources required to provide those services as follows:

         (a)     If the required resources are resources for which PSC and SBC
                 have established unit prices as described in Section 5(d) of
                 the EPI Agreement, PSC will be paid pursuant to the
                 established unit prices.

         (b)     If unit prices have not been established for the required
                 resources, PSC will be paid an amount to be mutually agreed.

         (c)     If PSC and SBC are unable to agree on an amount to be paid for
                 the required resources, PSC will be relieved of any
                 responsibility for the services with respect to the required
                 resources, except as set forth below and SBC will have the
                 right to have another third party, or its own staff, provide
                 the services and the resources required by the services that
                 are not within the Scope of Services, subject to PSC's





                                      F-4
<PAGE>   18



                 final right of refusal.  In such a situation, PSC will have a
                 final right of refusal as follows:

                 (1)      SBC will give PSC notice of the services and related
                          resources that it is proposing be provided by a third
                          party or its own staff.  The notice will include the
                          amounts that the third party proposes to charge, or
                          the costs SBC estimates it will itself incur, for
                          those services and related resources.

                 (2)      PSC will be given forty-five (45) days to respond to
                          the notice by notifying SBC whether it desires to
                          provide those services and related resources and the
                          price it offers to charge for those services.

                 (3)      Within forty-five (45) days of receiving PSC's
                          response, SBC will grant PSC the right to provide
                          those services and related resources, unless either
                          the price for such services offered by PSC is
                          meaningfully worse or SBC in good faith believes that
                          PSC has not demonstrated proficiency in the area of
                          the applicable services.

                 (4)      SBC may use a PSC Competitor to provide the
                          applicable services only if SBC and the PSC
                          Competitor act in good faith and not with the intent
                          to have the PSC Competitor "buy" the business and the
                          PSC Competitor charges SBC no less than its typical
                          retail rates for similar services.

5.       [Intentionally omitted]

6.       Invoices and Time of Payment.  The amounts payable to PSC hereunder
         will be invoiced and paid as follows:

         (a)     PSC will submit invoices to SBC for each month during the term
                 of this EPI Agreement.  Invoices will be submitted in the name
                 of any SBC Warburg Division Member and for any location that
                 is requested by SBC to cover Services delivered in that
                 location to that SBC Warburg Division Member, in a form that
                 is acceptable to the taxing authorities in the applicable
                 location.  Each invoice will contain information in a format
                 and with such detail as is reasonably necessary for SBC to
                 verify PSC's charges and to allocate PSC's charges among the
                 appropriate SBC Warburg Division Members.  PSC will also
                 provide an analysis of the charges in a manner consistent with
                 SBC's reasonable requests from time to time.

         (b)     Invoices for the amounts due pursuant to Sections 3(b), 4(b),
                 5(b) and 6(b) of this Schedule F will be submitted on or
                 before the first day of each calendar month and will be
                 payable by the tenth day of that calendar month.  Any amount
                 due PSC hereunder for which a time for payment is not
                 otherwise specified will be due and payable within thirty





                                      F-5
<PAGE>   19



                 (30) days after receipt by SBC of a PSC invoice therefor.  PSC
                 will submit such invoices on a timely basis promptly after
                 performing the Services or incurring the expenses that are
                 being invoiced.

         (c)     If SBC reasonably disputes any invoice in good faith, as SBC's
                 sole means of obtaining relief  related to the invoice, SBC
                 must  provide to PSC within nine (9) months of receipt of the
                 invoice concerning such dispute a detailed written reason for
                 its dispute and will pay to PSC all amounts due on the
                 invoice, except SBC may withhold  a portion of the Annual
                 Profit Amount having the same ratio to the Annual Profit
                 Amount invoiced for the month as to which a dispute exists as
                 the ratio of the amount in dispute to all amounts due to PSC
                 for the month associated with the PSC Costs being disputed by
                 SBC.  SBC will pay to PSC the PSC Interest Payment for any
                 late payments and withheld Annual Profit Amounts that are
                 ultimately determined to be due.  PSC will pay to SBC the SBC
                 Interest Payment for any amounts required to be reimbursed by
                 PSC to SBC as a result of SBC's payment to PSC of amounts that
                 are ultimately determined not to have been due.

         (d)     PSC's monthly invoices will include a pro-rata portion of the
                 Annual Profit Amount.  Adjustment to the Annual Profit Amount
                 to account for the aggregate sum of all Reward Percentages or
                 Penalty Percentages, as applicable, pursuant to Schedule G
                 will be determined by SBC and notified to PSC in writing in
                 accordance with Section 5(c)(5) of the EPI Agreement.  Payment
                 of any reward amount by SBC will be made simultaneously with
                 delivery of such notice to PSC.  Credit for any penalty amount
                 will by applied by PSC to the Monthly Run Rate for the
                 subsequent Budget Period.

         (e)     SBC will pay PSC the Special Profit Fee on or before May 31,
                 1997.

7.       Currency of Payment.  All charges to SBC will be invoiced in the
         currency of the country or countries, as the case may be, in which the
         PSC Costs related to the charges were incurred, and SBC will pay those
         PSC charges in the currency so denominated.  Upon the agreement of SBC
         and PSC at the beginning of any Budget Period, charges to SBC may be
         invoiced in U.S. Dollars.  The Annual Profit Amount will be invoiced
         in U.S. Dollars.

8.       Tax Credit.  As a reduction to any amounts billed to SBC under this
         Schedule F, PSC will apply a credit equal to the reduction in "Income
         Tax" resulting from the use of an "Existing Tax Asset" to the extent
         that "SBC Taxable Income" in any jurisdiction enables PSC to "Utilize"
         such Existing Tax Asset.  For purposes of this Section 8:

         (a)     "Income Tax" means the tax liability required to be calculated
                 under the relevant jurisdiction's income, profits or franchise
                 tax laws for any tax year.





                                      F-6
<PAGE>   20



         (b)     "Existing Tax Asset" means a net operating loss carryover, as
                 defined in the relevant jurisdiction's income, profits or
                 franchise  tax laws, that exists at December 31, 1995.

         (c)     "SBC Taxable Income" means the portion of PSC Group taxable
                 income before net operating loss carryover as presented on any
                 PSC Group final tax return for any tax year in any
                 jurisdiction that PSC allocates to this Agreement, using any
                 reasonable, good faith method.

         (d)     "Utilize" means to use the Existing Tax Asset on any PSC Group
                 final income tax return for any tax year in any jurisdiction,
                 but only to the extent that the Existing Tax Asset would not
                 otherwise be offset by non-SBC Taxable Income in the current
                 tax year or in any subsequent tax years.  For these purposes,
                 an Existing Tax Asset shall not be considered Utilized until a
                 final determination can be made that the Existing Tax Asset
                 would have expired unused but for availability of SBC Taxable
                 Income.  In making this determination, non-SBC Taxable Income
                 shall be applied to the oldest net operating loss carryovers
                 first.  Non-SBC Taxable Income shall mean any PSC Group
                 taxable income that is not SBC Taxable Income.

9.       Audit of Charges.  Upon the reasonable request of SBC, PSC will permit
         SBC or its designated representatives (who will not be PSC Competitors
         or Affiliates of PSC Competitors, other than the reporting auditors of
         any SBC Warburg Division Member) access to PSC's books and records to
         perform an audit up to four (4) times per Budget Period to the extent
         necessary to verify PSC's charges to SBC under this EPI Agreement.
         SBC will provide to PSC a copy of the audit report resulting from each
         such audit upon its completion.  As promptly as practicable
         thereafter, but within nine (9) months of the receipt by SBC of the
         invoice concerning the disputed cost, SBC must provide notice to PSC
         of a dispute and the parties will then review the audit report and
         work in good faith to agree upon any reimbursement of charges due to
         SBC and any appropriate future adjustments to PSC's charges and
         practices under this EPI Agreement.  Subject to the delivery of the
         notice referred to above, if such audit demonstrates that PSC's
         invoiced charges for that period differ from the correct charges for
         that period, PSC will either (i) issue a credit to SBC against the
         next succeeding monthly invoice for the amount of any overpayments, or
         (ii) issue an invoice to SBC for any underpayments, plus in the event
         of (i) above, interest on the credited amounts equal to the SBC
         Interest Rate calculated from the date such amounts were overpaid, and
         in the event of (ii) above, interest on the invoiced amounts equal to
         the PSC Interest Rate calculated from the date such amounts should
         have been paid.  If PSC's invoiced charges for the applicable period
         exceed the correct charges for that period by more than ten percent
         (10%), PSC will pay or reimburse SBC for the reasonable costs of such
         audit.  In the event PSC reasonably desires to limit the scope of
         SBC's audit rights in order to protect confidential or proprietary
         information, the audit will be conducted by an independent third party
         auditor mutually acceptable to PSC and SBC who will verify PSC's
         charges to SBC for the relevant period without disclosing any





                                      F-7

         Confidential Information of any member of the PSC Group to any member
         of the SBC Group or any other party.

                                   SCHEDULE F

                          BUDGET AND CAPACITY PLANNING

1.       PSC Costs Budget. The PSC Costs Budget will be established for each
         Budget Period as follows:

         (a)     SBC, in consultation with PSC, will determine the estimated
                 requirements of the SBC Warburg Division during that Budget
                 Period for the Cost Plus Services (the "Estimated Services")

         (b)     Following determination of the Estimated Services, PSC, in
                 consultation with SBC, will establish a proposed budget for
                 that Budget Period and PSC will submit the proposed budget to
                 SBC for SBC's written approval.  The budget submitted by PSC
                 will:

                 (1)      Reference the aggregate amount of PSC Costs that PSC
                          estimates it will incur in connection with providing
                          the Estimated Services.

                 (2)      Itemize the aggregate PSC Costs by a number and type
                          of expense categories to be mutually established from
                          time to time.

                 (3)      Allocate the budget over the total number of months
                          in that Budget Period (the "Monthly Run Rate") by
                          considering the month in which the various PSC Costs
                          will be incurred by PSC and allocate the Annual
                          Profit Amount on a pro-rata basis.

                 (4)      Take into account providing the Estimated Services in
                          accordance with any Performance Metrics that may have
                          been established.

         (c)    Upon receipt of PSC's proposed budget, SBC will either approve
                the budget as submitted or disapprove the budget as submitted
                and provide to PSC the aggregate amount of PSC Costs that SBC
                will approve for the budget.  If SBC does not approve PSC's
                proposed budget, PSC and SBC will work together to adjust the
                Services and, where applicable, the Performance Metrics, and
                to make any other appropriate adjustments, all as necessary to
                cause the budget to meet the total PSC Costs that SBC will
                approve for the budget.

         (d)    The final budget (the "PSC Costs Budget"), along with the
                Monthly Run Rate, for each Budget Period will be subject to
                SBC's final approval and will become the basis for PSC's
                determination of its estimated monthly charges to SBC for the
                Cost Plus Services.

2.       Equipment and Facilities Budget.  An Equipment and Facilities Budget
         will be established for each Budget Period as follows:

         (a)     PSC, in consultation with SBC, will establish a proposed
                 budget for that Budget Period covering the aggregate amount of
                 equipment and facilities expenditures that PSC estimates SBC
                 must directly incur in connection with the Services
                 contemplated by the PSC Costs Budget for that Budget Period
                 and PSC will submit the proposed budget to SBC for SBC's
                 written approval.  The budget submitted by PSC will:

                 (1)      itemize the aggregate equipment and facilities
                          expenditures by expense category to be mutually
                          established from time to time; and

                 (2)      allocate the budget over the total number of months
                          in that Budget Period (the "Monthly Capital Rate") by
                          considering the month in which the various equipment
                          and facilities expenditures will be incurred.

         (b)     Upon receipt of PSC's proposed budget, SBC will either approve
                 the budget as submitted or disapprove the budget as submitted
                 and provide to PSC the aggregate amount of equipment and
                 facilities expenditures that SBC will approve for the budget.
                 If SBC does not approve PSC's proposed budget, PSC and SBC
                 will work together to adjust the PSC Costs Budget, the
                 Services and, where applicable, the Performance Metrics
                 reflected in the applicable PSC Costs Budget, and to make any
                 other appropriate adjustments, all as necessary to cause the
                 Equipment and Facilities Budget to meet the total equipment
                 and facilities expenditures that SBC will approve for the
                 budget.

         (c)     The final budget (the "Equipment and Facilities Budget") for
                 each Budget Period will be subject to SBC's final approval.

3.       Quarterly Budget Review.  At the end of each calendar quarter during a
         Budget Period, PSC and SBC will jointly review (i) the Equipment and
         Facilities Budget and (ii) the PSC Costs Budget, by comparing the
         budgeted Monthly Run Rate and Monthly Capital Rate for that Budget
         Period to the actual monthly costs incurred during that Budget Period
         for each expense category reflected in the PSC Costs Budget or the
         Equipment and Facilities Budget, as applicable.  Based upon that
         review, SBC may make adjustments to the Monthly Run Rate, the PSC
         Costs Budget and the Equipment and Facilities Budget for the remainder
         of the Budget Period.  Additionally, based upon these quarterly
         reviews, PSC's charges to SBC will be adjusted as provided in Section
         3 to Schedule F.  Either party may request that adjustments occur more
         often than quarterly to take into account significant differences
         between actual PSC Costs and the Monthly Run Rate.

4.       Changes to Budgets.  PSC acknowledges and agrees that SBC may make
         changes to the PSC Costs Budget and the Equipment and Facilities
         Budget by providing prior notice to PSC.  SBC acknowledges and agrees
         that changes to either the PSC Costs Budget or the Equipment and
         Facilities Budget may result in changes to the Services and, where
         applicable, the Performance Metrics that SBC anticipates PSC will
         provide during the applicable Budget Period.  Subject to Section 8 of
         this Appendix, if PSC desires to make any changes to either the PSC
         Costs Budget or the Equipment and Facilities Budget, PSC will first
         obtain the prior approval of SBC.

5.       Additional Equipment.  If at any time during the term of this EPI
         Agreement, PSC elects to add any Equipment (excluding any personal
         computers, modems, printers or other related personal Equipment for
         use by PSC personnel) to the SBC Warburg Infrastructure, and the cost
         of the Equipment has been included in the Equipment and Facilities
         Budget covering the Budget Period in which the Equipment is to be
         purchased, PSC may purchase the Equipment, and the cost thereof will
         be chargeable to SBC.  If the cost of the Equipment has not been
         included in the Equipment and Facilities Budget covering the Budget
         Period in which the Equipment is to be purchased, PSC will notify SBC
         of its desire to add the Equipment to the SBC Warburg Infrastructure
         and the date by which PSC desires to order the Equipment, and if SBC
         consents to the purchase of the Equipment prior to the desired order
         date, PSC will purchase the Equipment on behalf of SBC and SBC will
         pay PSC therefor in accordance with this Schedule F.  Subject to the
         foregoing, PSC agrees that it will abide by any cost approval process
         of which PSC may receive notice from SBC from time to time, including
         the SBC Warburg Central Approval and Order Process, within a
         reasonable period of time after receipt thereof.

6.       Use of SBC Warburg Infrastructure.  Prior to the use by PSC of the SBC
         Warburg Infrastructure for any customer of PSC (other than an SBC
         Warburg Division Member), PSC will obtain the consent of SBC based
         upon a business case prepared by PSC for SBC's review and approval
         specifying (i) any capital investment that will be required from SBC
         to obtain any additional resources to provide services to the PSC
         customer and, if so, any payments that will be made to SBC in
         connection with or attributable to the use of the SBC Warburg
         Infrastructure, (ii) any impact on the overall operating expenses of
         the SBC Warburg Infrastructure, (iii) any impact the introduction of
         the third party customer would have on existing Performance Metrics
         and (iv) any impact on PSC's charges to SBC for the Services.  PSC
         shall also satisfy SBC, in SBC's sole discretion, that adequate
         security procedures have been instituted to prevent disclosure of any
         Confidential Information of SBC to the third party customer.

1.       Operational Plan.  PSC, on an annual basis, will update and provide to
         SBC a twelve (12) month operational plan for the Services to be
         provided by PSC under this Agreement, which will include plans for
         reducing PSC Costs and will establish suggested Performance Metrics
         for the Services.

<PAGE>   25



8.       Assignment of Costs.  Notwithstanding anything to the contrary in this
         Appendix or elsewhere in the EPI Agreement, SBC acknowledges and
         agrees that PSC may assign to SBC, and SBC will assume from PSC,
         responsibility for paying directly to the applicable third party
         vendor any costs that are then included in the PSC Costs.  In such
         event, the PSC Costs, the PSC Costs Budget, and the Monthly Run Rate
         will be decreased to reflect any such assignment.  Notwithstanding any
         assignment by PSC to SBC of any third-party costs pursuant to this
         Section 8, PSC will remain responsible for continuing to manage the
         Services to which the assigned costs are applicable.

                                   APPENDIX 2
                                       TO
                                   SCHEDULE F

                              INFLATION ADJUSTMENT



1.       Index.  As used in this Appendix, (i) the "Index" means the Implicit
         Price Deflator for the Gross Domestic Product, published by the Bureau
         of Economic Analysis, an agency of the U.S. Department of Commerce,
         (ii) the "Base Index" is the Index applicable to the Original
         Agreement Date and (iii) the "Base Profit Amount" means $41,000,000.

2.       Adjustment.

         (a)     Effective as of the third anniversary of the Original
                 Agreement Date,the Annual Profit Amount will be increased by
                 the percentage increase in the Index as of such date over the
                 Base Index.

         (b)     If, on any anniversary of the Original Agreement Date during
                 the term of this EPI Agreement after the third anniversary
                 referred to in clause (a) above (each, an "Inflation
                 Adjustment Date") the Index (the "Applicable Index") is higher
                 than the Base Index, then, effective as of such Inflation
                 Adjustment Date the Annual Profit Amount will be an amount
                 equal to (i) the Base Profit Amount plus (ii) the percentage
                 by which the Applicable Index exceeds the Base Index as of
                 such Inflation Adjustment Date multiplied by the Base Profit
                 Amount.

         (c)     Notwithstanding any other provision of this Appendix 2 to
                 Schedule F, the Annual Profit Amount will never be less than
                 $41,000,000 (other than for the first Budget Period, for which
                 it will be $40,500,000.

3.       Change of Index.  In the event that the Bureau of Economic Analysis
         should stop publishing the Index or should substantially change the
         content or format thereof, PSC and SBC will substitute therefor
         another comparable measure published by a mutually acceptable source.

                                   SCHEDULE G
                              PERFORMANCE METRICS

1.       Definitions.  For purposes of this Schedule G, the following
         definitions will apply:

         a.      "Penalty Percentage" is, with respect to each Performance
                 Metric, the percentage so designated in this Schedule G with
                 respect to that Performance Metric.  The aggregate sum of all
                 Penalty Percentages will not exceed 100%.

         b.      "Penalty Pool" is, with respect to any Budget Period during
                 the term of this EPI Agreement, an amount equal to thirty
                 percent (30%) of the Annual Profit Amount.

         c.      "Reward Percentage" is, with respect to each Performance
                 Metric, the percentage so designated in this Schedule G with
                 respect to that Performance Metric.  The aggregate sum of all
                 Reward Percentages will not exceed 100%.

         d.      "Reward Pool" is, with respect to any Budget Period during the
                 term of this EPI Agreement, an amount equal to fifteen percent
                 (15%) of the Annual Profit Amount.

2.       Performance Metrics Mechanics.  The Performance Metrics listed below
         in Section 3 are those in effect at the Adjustment Date.  It is the
         intention of SBC and PSC to continue to refine the Performance Metrics
         during the current Budget Period.

         a.      COST CONTROL

                 Reward Percentage:        25%
                 Penalty Percentage:       25%

         Budgetary control needs to be assessed in the context of an overall
         financial plan. PSC may request that the SBC Operational Manager
         review the financials on a monthly basis.  Actual costs in excess of
         the PSC Costs Budget are acceptable if approved by SBC.

         Examples include, but are not limited to:

    o    Increase in services or quality requested and approved by the client
    o    Agreed resource excess during a re-manning exercise
    o    SBC approved new projects or functions undertaken under the umbrella
         of business as usual
    o    SBC approved tooling up for third party use of functions on a
         commercial basis





                                      G-1
<PAGE>   28



         Unapproved cost overruns in excess of 15% of the PSC Costs Budget
         would be considered extreme and could lead to the imposition of the
         entire Penalty Percentage pertaining to this Performance Metric.  An
         unapproved cost overrun of 10% would be considered significant and
         could lead to the imposition of 50% of the Penalty Percentage
         pertaining to this Performance Metric.  These ranges are meant to be
         indicative and not absolute.  Unapproved cost overruns include not
         only PSC Costs but foreign currency dealing and costs incurred by SBC
         because of significant mis-estimates of the local currency
         sub-components of the budget.

         b.      BUSINESS SERVICE QUALITY AND SATISFACTION

                 Reward Percentage:        30%
                 Penalty Percentage:       30%

         SBC and PSC will establish a structure whereby the business areas and
         logistics functions of the SBC Warburg Division have an input
         mechanism into this Performance Metric.  Structured correctly, this
         can be used over time to establish specific objectives and measures by
         business areas which can be agreed on a bilateral basis.  The PSC
         Relationship Manager will initiate a quarterly meeting with the SBC
         Operational Manager.  This meeting should follow separate meetings
         initiated by the PSC Operational Manager with each business area and
         logistic function leader or designee with the key PSC service
         providers of those businesses as well as the PSC Operational Manager.
         Minutes of these meetings should be submitted to the SBC Operational
         Manager and the PSC Relationship Manager for purposes of the quarterly
         meeting referenced above.  The initial formal meetings (all of which
         will be minuted) will establish current status as well as goals for
         the rest of the Budget Period to enable assessment to be made against
         these goals in an objective manner.  Any business area or logistics
         function not taking part in this process, as requested with reasonable
         notice by PSC, will be deemed to be submitting a neutral performance
         recommendation for that period  This would not preclude the business
         areas or logistics functions contributing to performance evaluation
         annually (or quarterly, if applicable), provided that for the period
         during which the business area or logistic function does not take part
         in this process, the PSC performance will be deemed to be at the zero
         percent (0%) Penalty Percentage.  It is understood that although each
         business area or logistics function must participate in quarterly
         reviews in order to maintainits discretion over this Performance
         Metric for each respective quarter, having thus participated they
         retain full control of the performance review for the full year Budget
         Period up to the final annual review.

         c.      PROJECT MANAGEMENT

                 Reward Percentage:        25%
                 Penalty Percentage:       25%





                                      G-2
<PAGE>   29




         Each project requires detailed plans from PSC and mutually agreed
         deliverables such that the performance of PSC can be assessed.

         Each project  should  have a SBC business sponsor who should chair
         regular progress meetings (which should be minuted) to monitor
         progress of the project.  These meetings should monitor the agreed
         performance criteria as well as any changes in circumstances that
         affect these measures.

         The chairmen of these projects should report into the quarterly
         meeting mentioned above between the SBC Operational Manager and the
         PSC Relationship Manager.

         d.      SUBJECTIVE MEASURES

                 Reward Percentage:        20%
                 Penalty Percentage:       20%

         There will be a number of subjective inputs to the assessment of PSC
         performance, some of which are detailed below:

         o   Perceived effectiveness of the PSC management team and its added
             value to the SBC-PSC alliance overall
         o   Value added of PSC in technology thought leadership and strategic
             and structural contributions
         o   Relationship with the organization
         o   Support of SBC Warburg Division policies and attitude (e.g.,
             security, standards, audit and cost consciousness)
         o   Proactive leadership in support of the business as a whole (e.g.,
             forcing focus on issues which are relevant to the account,
             examples would be 'year 2000', structural improvements in the cost
             base and a meaningful and accurate budget process).

3.       Penalty Amount.  With respect to each period (quarterly or annual, as
         applicable pursuant to Section 5(c) of the EPI Agreement) in which
         PSC's performance of the Services fails to meet or fails to exceed the
         standards which have been mutually established for a Performance
         Metric, PSC will provide to SBC a credit in an amount equal to the
         product of (i) the Penalty Percentage for that Performance Metric,
         multiplied by (ii) the Penalty Pool for that Budget Period or a
         quarter thereof, as applicable; provided, however, that the maximum
         amount of credit that PSC is obligated to provide to SBC pursuant to
         this Section 3 in any one Budget Period or a quarter thereof, as
         applicable,  with respect to all Performance Metrics shall not exceed,
         in the aggregate, the Penalty Pool for that Budget Period or a quarter
         thereof, as applicable.

4.       Reward Amount.  With respect to each period (quarterly or annual, as
         applicable pursuant to Section 5(c) of the EPI Agreement) in which
         PSC's performance of the Services meets or exceeds the standards which
         have been mutually established for a Performance Metric, SBC will pay
         to PSC an amount equal to the product of (i) the Reward Percentage for
         that Performance Metric, multiplied





                                      G-3
<PAGE>   30



         by (ii) the Reward Pool for that Budget Period or a quarter thereof,
         as applicable; provided, however, that the maximum additional amount
         that SBC is obligated to pay to PSC pursuant to this Section 4 in any
         one Budget Period or a quarter thereof, as applicable,  with respect
         to all Performance Metrics shall not exceed, in the aggregate, the
         Reward Pool for that Budget Period or a quarter thereof, as
         applicable.
