                   28,360,000 SHARES OF CLASS A COMMON STOCK

                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION

    Of  the 28,360,000 shares of Class A Common Stock, par value $.01 per share,
of the Company (the  "Class A Common Stock")  offered hereby, 28,151,000  shares
may  be offered and  sold by the Company  and 209,000 shares  may be offered and
sold by  certain directors  of  the Company  (the "Selling  Stockholders").  See
"Securities Offered by the Prospectus." The Company will not receive any portion
of the net proceeds from the sale of shares by the Selling Stockholders.

    The  28,151,000 shares of  Class A Common  Stock offered by  the Company are
anticipated to be offered  as follows: (i) 3,000,000  shares may be offered  and
sold  by the Company (including shares  sold by stockholders through the limited
market maintained by Bull, Inc. (the "Limited Market"), the sale of which may be
attributed to  the Company)  to present  and future  employees, consultants  and
directors  and  to  the  trustees  for  the  benefit  of  employees  of  certain
subsidiaries of the Company under their retirement plans; (ii) 50,000 shares may
be issued and  delivered to a  trustee for  the benefit of  employees under  the
Company's  Profit  Sharing Retirement  Plan II;  (iii)  1,500,000 shares  may be
issued and  delivered  to a  trustee  for the  benefit  of employees  under  the
Company's Employee Stock Ownership Plan; (iv) 2,250,000 shares may be issued and
delivered  to a trustee for the benefit of employees under the Company's Cash or
Deferred Arrangement;  (v) 1,000,000  shares  may be  awarded to  employees  and
directors  under the Company's 1984 Bonus Compensation Plan; (vi) 600,000 shares
may be issued and delivered to a trustee for the benefit of employees under  the
Company's  Stock Compensation Plan and Management Stock Compensation Plan; (vii)
441,000 shares may be offered and sold to a trustee or agent for the benefit  of
employees  under the  Company's 1993  Employee Stock  Purchase Plan;  and (viii)
19,310,000 shares  may  be issued  upon  the  exercise of  options  granted  and
available  to be granted under  the Company's 1982 and  1992 stock option plans.
The foregoing allocation of the total  shares offered by the Company  represents
the  Company's  current  anticipated use  of  such  shares and  is  provided for
illustrative purposes only. The actual number of shares offered and sold by  the
Company under each category may exceed or be less than the indicated number. All
of  the shares of Class A Common Stock offered hereby will be subject to certain
restrictions (including restrictions on their transferability) set forth in  the
Company's  Certificate of Incorporation (the "Certificate of Incorporation") and
may be subject to  certain other contingencies. See  "Securities Offered by  the
Prospectus,"  "Employee  Benefit Plans"  and  "Description of  Capital  Stock --
Common Stock -- Restrictions on Class A Common Stock." The Selling  Stockholders
and  all other stockholders  (other than the  Company) will pay  a commission to
Bull, Inc., a wholly-owned  subsidiary of the Company,  equal to two percent  of
the proceeds from the sale of shares of Class A Common Stock sold by them in the
Limited  Market.  Bull, Inc.  is a  registered  broker-dealer whose  business is
limited to  effecting  purchases and  sales  of the  Company's  securities.  See
"Market Information -- The Limited Market."
                           --------------------------
THESE  SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
  EXCHANGE  COMMISSION  NOR  HAS  THE  COMMISSION  PASSED  UPON  THE  ACCURACY
    OR  ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY  IS
                              A CRIMINAL OFFENSE.
                           --------------------------

    The purchase price  of the shares  of Class A  Common Stock offered  hereby,
other  than those shares issuable upon exercise  of options or awarded under the
Company's 1984 Bonus Compensation Plan,  the Management Stock Compensation  Plan
or  the Stock Compensation Plan, will be  the formula price described below (the
"Formula Price"). The Formula Price is reviewed four times each year,  generally
in  conjunction with Board  of Directors meetings  which are currently scheduled
for April, July, October and January and is subject to the limitation that in no
case may it be less than 90% of the  net book value per share of Class A  Common
Stock  at the end of the quarter immediately preceding the date on which a price
revision is to occur. The  price applicable to shares  of Class B Common  Stock,
par  value $.05 per share,  of the Company (the "Class  B Common Stock") will be
equal to five times the Formula Price. The Formula Price is determined according
to the following formula (the  "Formula"): the price per  share is equal to  the
sum of (i) a fraction, the numerator of which is the stockholders' equity of the
Company at the end of the fiscal quarter immediately preceding the date on which
a price revision is to occur ("E") and the denominator of which is the number of
outstanding common shares and common share equivalents at the end of that fiscal
quarter ("W(1)"), and (ii) a fraction, the numerator of which is 5.66 multiplied
by the market factor ("M" or "Market Factor"), multiplied by the earnings of the
Company  for the four  fiscal quarters immediately  preceding the price revision
("P"),  and  the  denominator  of  which  is  the  weighted  average  number  of
outstanding  common shares  and common share  equivalents for  those four fiscal
quarters, as used by the Company in computing primary earnings per share  ("W").
The  number of outstanding common shares  and common share equivalents described
above assumes the conversion  of each share  of Class B  Common Stock into  five
shares  of Class  A Common Stock.  The 5.66  multiplier is a  constant which was
first included in the Formula  in March 1976. The  Market Factor is a  numerical
factor  which  is  intended  to reflect  existing  securities  market conditions
relevant to the valuation  of the Class  A Common Stock and  the Class B  Common
Stock.  The  Market  Factor is  generally  reviewed  quarterly by  the  Board of
Directors in conjunction with an appraisal  which is prepared by an  independent
appraisal   firm  for  the  committee   administering  the  Company's  qualified
retirement plans (the "Committee") and which is relied upon by the Committee and
the Board of Directors. See "Market Information -- Price Range of Class A Common
Stock and Class B Common Stock." Since  January 14, 1994, the Market Factor  has
been  1.5. Prior thereto  and since April  12, 1991, the  Market Factor was 1.4.
Subject to the  limitation set forth  above, the  Formula Price of  the Class  A
Common Stock, expressed as an equation, is as follows:

<TABLE>
<S>                <C>        <C>        <C>

                     W(1)                    W
</TABLE>

    On  April 9, 1994, the Formula Price was $14.46, and the price for the Class
B Common Stock was $72.30.

                                  THE COMPANY

    The   Company  provides  diversified  professional  and  technical  services
("Technical Services") to and designs, develops and manufactures high-technology
products ("Products") for  its customers. The  Company's Technical Services  and
Products  have  primarily been  sold  to departments  and  agencies of  the U.S.
Government, including the  Department of Defense  ("DOD"), Department of  Energy
("DOE"),  Department of  Transportation ("DOT"), Department  of Veterans Affairs
("VA"), Environmental  Protection Agency  ("EPA") and  National Aeronautics  and
Space  Administration ("NASA").  Revenues generated  from the  sale of Technical
Services and Products to the U.S. Government as a

                                       2
<PAGE>
prime contractor or subcontractor accounted for 88% of revenues in fiscal  years
1994,  1993 and 1992. The balance of  the Company's revenues are attributable to
the sales of Technical Services and Products to foreign governments,  commercial
customers and others.

    The  percentage of revenues attributable  to Technical Services and Products
has remained relatively constant at approximately 92% and 8%, respectively,  for
fiscal  years  1994,  1993 and  1992.  Within Technical  Services,  revenues are
further classified  between  "National  Security"  "Environment,"  "Energy"  and
"Other  Technical Services," the latter of  which includes the Company's health,
space, transportation and commercial information technology business areas.  The
percentage  of  Technical Services  revenues  attributable to  National Security
related work has declined  gradually as a percentage  of total revenues and  was
50%  of Technical Services revenues for fiscal  year 1994. For fiscal year 1994,
the Environment, Energy  and other Technical  Services business areas  accounted
for 15%, 9% and 17%, respectively, of total revenues.

    The  Company's principal executive offices are located at 10260 Campus Point
Drive, San Diego, California  92121, telephone (619) 546-6000.  As used in  this
Prospectus,  all references to the Company include, unless the context indicates
otherwise, Science Applications  International Corporation  and its  predecessor
and subsidiary corporations.

                              GOVERNMENT CONTRACTS

    Many  of the U.S. Government programs in which the Company participates as a
contractor or subcontractor may extend for several years; however, such programs
are normally  funded on  an  annual basis.  All  U.S. Government  contracts  and
subcontracts  may be modified, curtailed or terminated at the convenience of the
government if program requirements or budgetary constraints change. In the event
that a contract is terminated for  convenience, the Company would be  reimbursed
for  its allowable  costs through the  date of  termination and would  be paid a
proportionate amount of the  stipulated profit or fee  attributable to the  work
actually performed.

    Termination  or curtailment of  major programs or  contracts of the Company,
particularly in research and development,  could have a material adverse  effect
on  the results of the Company's  operations. Although such contract and program
terminations have not had a material adverse effect on the Company in the  past,
no  assurance can be given that  curtailments or terminations of U.S. Government
programs or contracts will not have a material adverse effect on the Company  in
the future.

    The  Company's  business with  the U.S.  Government  and other  customers is
generally performed  under cost-reimbursement,  time-and-materials,  fixed-price
level-of-effort   or  firm   fixed-price  contracts.   Under  cost-reimbursement
contracts, the  customer  reimburses  the  Company  for  its  direct  costs  and
allocable   indirect  costs,   plus  a  fixed   fee  or   incentive  fee.  Under
time-and-materials contracts, the Company is paid for labor hours at  negotiated
hourly  rates and  reimbursed for other  allowable direct costs  at actual costs
plus allocable indirect costs. Under fixed-price level-of-effort contracts,  the
customer  pays the Company for the actual  labor hours provided to the customer,
at negotiated hourly  rates. Under  firm fixed-price contracts,  the Company  is
required  to provide stipulated products, systems or services for a fixed price.
Because the Company assumes the risk  of performing a firm fixed-price  contract
at the stipulated price, the failure to accurately estimate ultimate costs or to
control costs during performance of the work could result, and in some instances
has  resulted, in losses. During  the fiscal years ended  January 31, 1994, 1993
and 1992, approximately 65%,  62% and 62%,  respectively, of Technical  Services
revenues  were derived from  cost-reimbursement type contracts  and 12%, 16% and
22%, respectively, of the Technical Services revenues were from firm fixed-price
type  contracts  with  the  balance  from  time-and-materials  and   fixed-price
level-of-effort  type contracts. In contrast,  the majority of Products revenues
is derived from firm fixed-price type contracts.

    Any costs incurred by the  Company prior to the  execution of a contract  or
contract  amendment are incurred at the Company's  risk, and it is possible that
such costs will not be reimbursed by the customer. Unbilled receivables in  this
category which were included in the Technical Services segment contract revenues
at  January 31,  1994 were  $16,047,000. Unbilled  receivables in  this category
which

                                       3
<PAGE>
were included in the Products segment contract revenues at January 31, 1994 were
$181,000. Although no  assurance can  be given  that the  contracts or  contract
amendments  will be received  or that the  related costs will  be recovered, the
Company expects to recover substantially all such costs.

    Contract costs for  services or  products supplied to  the U.S.  Government,
including  allocated indirect  costs, are  subject to  audit and  adjustments by
negotiations between the Company  and U.S. Government representatives.  Indirect
contract  costs have been agreed upon through  the fiscal year ended January 31,
1990. Contract revenues for subsequent years have been recorded in amounts which
are expected to be realized upon final settlement. However, no assurance can  be
given  that  audits and  adjustments  for subsequent  years  will not  result in
decreased revenues or profits for those years.

    The Company is from time to time subject to certain Government inquiries and
investigations of its business  practices. The Company  does not anticipate  any
action  as a  result of  such inquiries  and investigations  which would  have a
material adverse effect  on its  consolidated financial position  or results  of
operations or its ability to conduct business. On February 15, 1994, the Company
was  served  with  search warrants  and  a  subpoena for  documents  and records
associated with the performance by an operating unit of the Company under  three
contracts  with the  DOD. The  search warrants and  the subpoena  state that the
Government is  seeking evidence  regarding the  making of  false statements  and
false  claims to  the DOD, as  well as  conspiracy to commit  such offenses. The
Company  has  not  been  apprised  of   the  details  that  the  Government   is
investigating  nor has  it been  charged with  any wrongdoing.  Accordingly, the
Company is unable to  assess the impact,  if any, of  this investigation on  its
consolidated  financial position,  results of  operations or  ability to conduct
business. For additional information concerning the investigation, reference  is
made  to the Form 8-K Report filed by  the Company on February 18, 1994 with the
SEC, which Form 8-K Report is incorporated herein by reference.

                      SECURITIES OFFERED BY THE PROSPECTUS

CLASS A COMMON STOCK OFFERED BY THE COMPANY

    The shares of Class  A Common Stock  offered by the  Company may be  offered
directly  or  contingently  to  present and  future  employees,  consultants and
directors of  the Company  or pursuant  to  the employee  benefit plans  of  the
Company  or its subsidiaries  as described below. The  Company believes that its
success  is  principally  dependent  upon   the  abilities  of  its   employees,
consultants  and  directors. Therefore,  since  its inception,  the  Company has
pursued a  policy of  offering such  persons an  opportunity to  make an  equity
investment  in the Company as an inducement  to such persons to become or remain
employed by or affiliated with the Company.

  DIRECT AND CONTINGENT SALES TO EMPLOYEES, CONSULTANTS, DIRECTORS AND CERTAIN
  SUBSIDIARY RETIREMENT PLANS

    At the discretion of  the Board of Directors  or the Operating Committee  of
the  Board of  Directors (the  "Operating Committee"),  employees, directors and
consultants may be offered  an opportunity to purchase  in the Limited Market  a
specified  number of the shares of Class A Common Stock offered hereby. All such
direct and contingent sales to employees, directors and consultants are effected
through the Limited Market and may be attributed to the Company. Pursuant to the
Certificate of Incorporation, all shares of Class A Common Stock offered by  the
Company,  directly or contingently,  to its employees,  consultants or directors
are subject  to  a  right of  first  refusal  and a  right  of  repurchase  upon
termination  of employment or affiliation. See  "Description of Capital Stock --
Common Stock -- Restrictions on Class A Common Stock." In addition, the trustees
of certain retirement plans of subsidiaries  of the Company may purchase  shares
in  the  Limited Market  on  behalf of  plan  participants, which  sales  may be
attributable to the Company.

  PROFIT SHARING RETIREMENT PLAN II

    The Company maintains a profit sharing retirement plan (the "Profit  Sharing
Retirement  Plan II") which is intended to  be qualified under Section 401(a) of
the Internal Revenue Code of 1986, as

                                       4
<PAGE>
amended (the "Code"). Generally, employees of eligible groups within the Company
who have attained the age of 21, completed 12 months of employment and completed
850 hours of  service with  the Company during  one of  the applicable  12-month
computational  periods are  eligible to participate  as of  the next semi-annual
entry date. Interests of participants in  the Profit Sharing Retirement Plan  II
vest  in accordance with a vesting schedule and other vesting rules set forth in
the Plan. Benefits are payable to a participant in cash within certain specified
time periods  following  such participant's  retirement,  permanent  disability,
death  or other  termination of employment.  The amount of  the Company's annual
contribution to the  Profit Sharing  Retirement Plan  II is  determined by,  and
within  the discretion of, the Board of Directors and may be in the form of cash
or Class  A  Common Stock.  To  the extent  permitted  under the  rules  of  the
committee  administering the Plan, each participant may designate that up to 20%
of the Company's contributions  allocated to his or  her account be invested  in
securities  of  the  Company.  See "Employee  Benefit  Plans  --  Profit Sharing
Retirement Plan II."

  EMPLOYEE STOCK OWNERSHIP PLAN

    The Company maintains an employee stock ownership plan (the "Employee  Stock
Ownership Plan") which is a stock bonus retirement plan intended to be qualified
under Section 401(a) of the Code. Generally, employees who have attained the age
of 21, completed 12 months of employment and completed 850 hours of service with
the  Company during  one of  the applicable  12-month computational  periods are
eligible to participate as of the next semi-annual entry date, except  employees
of  groups or units  designated as ineligible. Interests  of participants in the
Employee Stock Ownership  Plan vest in  accordance with a  vesting schedule  and
other  vesting rules set forth in the Plan. Each participant, however, is at all
times 100%  vested  in  any  amounts  transferred  from  the  Cash  or  Deferred
Arrangement. Benefits are generally payable to a participant in cash, unless the
participant  elects, subject  to requirements and  limitations set  forth in the
Employee Stock Ownership Plan, to receive a distribution in shares of stock, and
are payable within certain specified  time periods following such  participant's
retirement,  permanent disability, death or other termination of employment. The
amount of the Company's annual contribution to the Employee Stock Ownership Plan
is determined by, and within the discretion  of, the Board of Directors and  may
be  in the form of cash or Class  A Common Stock. Pursuant to the Employee Stock
Ownership Plan  and the  Certificate of  Incorporation, any  shares of  Class  A
Common  Stock  distributed out  of  the Employee  Stock  Ownership Plan  will be
subject to a right of  first refusal on behalf of  the Company and the  Employee
Stock  Ownership  Plan,  but will  not  be  subject to  the  Company's  right of
repurchase upon termination of employment or affiliation. See "Employee  Benefit
Plans  -- Employee  Stock Ownership Plan"  and "Description of  Capital Stock --
Common Stock -- Restrictions on Class A Common Stock."

  CASH OR DEFERRED ARRANGEMENT

    The Company maintains a Cash or  Deferred Arrangement (the "CODA") which  is
intended  to be qualified under Sections 401(a)  and (k) of the Code. Generally,
all employees are  eligible to participate,  except for employees  of groups  or
units  designated  as ineligible.  The CODA  permits a  participant to  elect to
defer, for  federal  income  tax  purposes,  a portion  of  his  or  her  annual
compensation  and to have such amount contributed directly by the Company to the
CODA for his or her  benefit. The Company may, but  is not obligated to, make  a
matching  contribution for the benefit of those participants who have elected to
defer a portion of their compensation.  The amount of the matching  contribution
currently  is equal to 30%  of the first $2,000 and  15% of amounts above $2,000
which participants have elected to defer in that year. No matching  contribution
is   provided  on  amounts  deferred  in   excess  of  10%  of  a  participant's
compensation. Further, employees of certain  participating groups or units  have
been  designated as ineligible  to receive a  matching contribution. The Company
may also make additional contributions in order to comply with Section 401(k) of
the Code. The Company's contributions  to the CODA are  made in cash unless  the
Board  of Directors determines  to make the  contributions in shares  of Class A
Common Stock or some other form. Each participant is at all times 100% vested in
his or her CODA account.  Benefits are payable to  a participant in cash  within
certain   specified  time  periods   following  such  participant's  retirement,
permanent disability, death  or other termination  of employment. See  "Employee
Benefit Plans -- CODA."

  BONUS COMPENSATION PLAN

    The  Company maintains  a bonus  compensation plan  (the "Bonus Compensation
Plan") which provides for the payment of bonuses in cash and/or shares of  Class
A Common Stock to officers, directors and employees. Awards of shares of Class A
Common  Stock are  distributed during  each fiscal  year and  may be  subject to
forfeiture, in  whole  or in  part,  in the  event  of the  termination  of  the
recipient's  employment or affiliation with the  Company prior to the expiration
of certain  vesting periods  as determined  by the  committee administering  the
Plan. Pursuant to the Certificate of Incorporation, all shares of Class A Common
Stock  awarded pursuant to  the Bonus Compensation  Plan will be  subject to the
Company's right of  first refusal  and the  Company's right  of repurchase  upon
termination  of employment or affiliation. See  "Employee Benefit Plans -- Bonus
Compensation Plan"  and  "Description  of  Capital  Stock  --  Common  Stock  --
Restrictions on Class A Common Stock."

  STOCK COMPENSATION PLANS

    On  April 9, 1994,  the Company adopted the  Stock Compensation Plan ("Stock
Compensation Plan")  and the  Management  Stock Compensation  Plan  ("Management
Stock  Compensation  Plan"), together  referred  to as  the  "Stock Compensation
Plans." The  Stock Compensation  Plans  provide for  awards  of Share  Units  to
eligible  employees of  the Company, which  Share Units  generally correspond to
shares of Class  A Common Stock  which are held  in a trust  for the benefit  of
participants in the Stock Compensation Plans, but which are subject to claims of
creditors  of the Company  in the event  of the bankruptcy  or insolvency of the
Company. Awards under the Stock Compensation Plans are subject to forfeiture, in
whole or in part, in the event of termination of the recipient's employment with
the Company, commencement of a leave of absence from the Company (other than for
disability, qualified  military  leave or  qualified  family medical  leave)  or
conversion  to consulting employee status prior  to the expiration of applicable
vesting  periods  as  determined  by  the  committee  administering  the   Stock
Compensation  Plans. Pursuant to the Certificate of Incorporation, all shares of
Class A  Common Stock  distributed  from the  trust  associated with  the  Stock
Compensation  Plans will be subject to the  Company's right of first refusal and
the Company's right of repurchase upon termination of employment. See  "Employee
Benefit  Plans -- Stock Compensation Plans" and "Description of Capital Stock --
Common Stock -- Restrictions on Class A Common Stock."

  EMPLOYEE STOCK PURCHASE PLAN

    The Company  maintains the  1993 Employee  Stock Purchase  Plan (the  "Stock
Purchase Plan") for the benefit of substantially all of its employees. The Stock
Purchase  Plan provides for the purchase of Class A Common Stock through payroll
deductions by participating employees and  is intended to qualify under  Section
423(b)  of the Code.  Participants contribute 95%  of the purchase  price of the
Class A Common Stock and the Company contributes the remaining five percent. All
shares purchased pursuant to the Stock Purchase Plan will be distributed  within
90  days  after the  end of  the plan  year  in which  they were  purchased and,
pursuant to the Certificate of Incorporation,  will be subject to the  Company's
right of first refusal and the Company's right of repurchase upon termination of
employment or affiliation. The Stock Purchase Plan will expire on July 31, 1995.
See   "Employee  Benefit  Plans  --  1993  Employee  Stock  Purchase  Plan"  and
"Description of Capital Stock -- Common Stock -- Restrictions on Class A  Common
Stock."

  STOCK OPTION PLANS

    Pursuant  to the Company's 1992 Stock  Option Plan, the Company grants stock
options to certain  of its  employees, consultants and  directors. Although  the
Company's  1982 Stock Option Plan terminated on  June 10, 1992 and no additional
stock options  can be  granted under  that Plan,  certain stock  options  remain
outstanding.  Stock  options under  the 1992  Stock Option  Plan may  be granted
contingent upon an employee or consultant obtaining a certain level of  contract
awards  for  the Company  within a  specified period  or upon  other performance
criteria and, in many cases, a requirement that such individual also purchase  a
specified  number of shares of Class A Common Stock in the Limited Market at the
prevailing Formula  Price. Pursuant  to the  Certificate of  Incorporation,  all
shares  of Class A Common Stock issuable upon the exercise of such stock options
will be subject to the

                                       6
<PAGE>
Company's right of  first refusal  and the  Company's right  of repurchase  upon
termination  of employment or affiliation. See  "Employee Benefit Plans -- Stock
Option Plans" and "Description of Capital Stock -- Common Stock --  Restrictions
on Class A Common Stock."

the Class  A  Common  Stock  being  offered hereby  in  the  Limited  Market  or

other  stockholders  participating   in  the  Limited   Market  and,  like   all

                               MARKET INFORMATION

THE LIMITED MARKET

    Since  its  inception,  the  Company  has  followed  a  policy  of remaining
essentially employee owned. As a result,  there has never been a general  public
market  for any of the  Company's securities. In order  to provide liquidity for
its stockholders, however, the Company has maintained a limited secondary market
(the "Limited Market")  through its wholly-owned  subsidiary, Bull, Inc.,  which
was organized in 1973 for the purpose of maintaining the Limited Market.

    The Limited Market generally permits existing stockholders to sell shares of
Class A Common Stock on four predetermined days each year (each a "Trade Date").
All shares of Class B Common

                                       8
<PAGE>
Stock  to be sold in the Limited Market  must first be converted into five times
as many shares of  Class A Common  Stock. All sales are  made at the  prevailing
Formula  Price to employees,  consultants and directors of  the Company who have
been approved by  the Board  of Directors or  the Operating  Committee as  being
entitled to purchase up to a specified number of shares of Class A Common Stock.
In  addition, the trustees  of the Company's Profit  Sharing Retirement Plan II,
Employee Stock Ownership Plan,  CODA, 1993 Employee  Stock Purchase Plan,  Stock
Compensation  Plans and certain  retirement plans of  the Company's subsidiaries
may also purchase shares of Class A Common Stock for their respective trusts  in
the  Limited Market. All sellers in the  Limited Market (other than the Company)
pay Bull, Inc.  a commission  equal to  two percent  of the  proceeds from  such
sales. No commission is paid by purchasers in the Limited Market.

    In the event that the aggregate number of shares offered for sale is greater
than  the aggregate number of shares sought to be purchased by authorized buyers
and the Company, offers to sell 500 shares or less of Class A Common Stock or up
to the first  500 shares if  more than 500  shares of Class  A Common Stock  are
offered by any seller will be accepted first. Offers to sell shares in excess of
500  shares  of  Class A  Common  Stock will  be  accepted on  a  pro-rata basis
determined by  dividing the  total  number of  shares remaining  under  purchase
orders  by the total number of shares  remaining under sell orders. If, however,
there are insufficient purchase orders to support the primary allocation of  500
shares  of Class  A Common  Stock for  each proposed  seller, then  the purchase
orders will be allocated  equally among all  of the proposed  sellers up to  the
total number of shares offered for sale. To the extent that the aggregate number
of  shares sought to be purchased exceeds the aggregate number of shares offered
for sale, the Company may, but is not obligated to, sell authorized but unissued
shares of Class A Common Stock in the Limited Market.

    The Company is currently  authorized, but not obligated,  to purchase up  to
1,250,000  shares of  Class A Common  Stock in  the Limited Market  on any Trade
Date, but only if and to the extent  that the number of shares offered for  sale
by  stockholders  exceeds  the  number  of  shares  sought  to  be  purchased by
authorized buyers and the  Company, in its discretion,  determines to make  such
purchases.  The Company did not purchase shares  in the Limited Market in fiscal
year 1994.  In fiscal  year 1993,  the Company  purchased 54,559  shares in  the
Limited  Market. The Company's purchases in fiscal year 1993 accounted for 2% of
the total shares purchased by all buyers in the Limited Market during that year.

    During the 1994 and 1993 fiscal years, the trustees of the Company's  Profit
Sharing  Retirement  Plan  II,  Employee Stock  Ownership  Plan,  CODA  and 1993
Employee Stock  Purchase Plan  purchased an  aggregate of  1,824,077 shares  and
1,808,961 shares, respectively, in the Limited Market. These purchases accounted
for approximately 81% and 79% of the total shares purchased by all buyers in the
Limited  Market during fiscal years 1994  and 1993, respectively. Such purchases
may change  in the  future, depending  on  the levels  of participation  in  and
contributions  to  such plans  and the  extent to  which such  contributions are
invested in Class A Common Stock. To  the extent that purchases by the  trustees
of the Company's employee benefit plans decrease and purchases by the Company do
not  increase, the ability of stockholders to resell their shares in the Limited
Market will likely be adversely affected.

    The Company received a no-action letter from the SEC (the "SEC Letter") that
authorizes the Company and the Employee  Stock Ownership Plan to commence on  an
annual  basis,  at the  Company's discretion,  a joint  tender offer  (a "Tender
Offer") to purchase all  shares of the  Company's Class A  Common Stock held  by
persons  who  are not  directors, employees  or consultants  of the  Company (or
family members of, or trustees for, such employees, directors or consultants  of
the  Company)  as  of the  date  the  Tender Offer  is  commenced  (the "Outside
Stockholders"). Under  current federal  income tax  laws, the  Tender Offer,  as
structured, would allow Outside Stockholders who tender certain shares purchased
by  the Employee Stock Ownership Plan to defer the payment of federal income tax
under Section  1042 of  the Code  on any  capital gain  derived from  the  sale,
provided certain conditions are met.

                                       9

    The  Company and the Employee Stock Ownership Plan have completed one Tender
Offer pursuant to which the Employee Stock Ownership Plan purchased on  November
20, 1992 an aggregate of 700,444 shares of Class A Common Stock from 186 Outside
Stockholders.  The Company  has not  yet determined  whether it  will commence a
Tender Offer during calendar year 1994. There can be no assurance that a  Tender
Offer  will  be  commenced in  the  future or,  if  commenced, that  it  will be
completed. If a Tender Offer  is undertaken in the  future, the Company will  be
required  to take  certain actions  to ensure  that such  Tender Offer  does not
negatively affect the  liquidity of the  Limited Market on  the Trade Date  upon
which such Tender Offer is completed.

PRICE RANGE OF CLASS A COMMON STOCK AND CLASS B COMMON STOCK

    The  Formula  set forth  on the  cover page  of this  Prospectus is  used to
determine the Formula  Price at which  the Class  A Common Stock  trades in  the
Limited  Market. The Formula  Price is reviewed  at least four  times each year,
generally in conjunction with  Board of Directors  meetings which are  currently
scheduled for April, July, October and January, and is subject to the limitation
that  the price may not be less than 90%  of the net book value per share of the
Class A Common Stock at the end of the quarter immediately preceding the date on
which  the  price  revision  is  to  occur.  Pursuant  to  the  Certificate   of
Incorporation,  the price applicable to shares of  Class B Common Stock is equal
to five times the Formula Price.

    The Formula  Price is  determined according  to the  following formula:  the
price per share is equal to the sum of (i) a fraction, the numerator of which is
the  stockholders'  equity of  the  Company at  the  end of  the  fiscal quarter
immediately preceding the date on which a  price revision is to occur ("E")  and
the  denominator of which is the number  of outstanding common shares and common
share equivalents  at  the  end of  such  fiscal  quarter ("W(1)")  and  (ii)  a
fraction, the numerator of which is 5.66 multiplied by the market factor ("M" or
"Market  Factor"), multiplied by the earnings of the Company for the four fiscal
quarters immediately preceding the price revision ("P"), and the denominator  of
which  is the  weighted average number  of outstanding common  shares and common
share equivalents for  those four  fiscal quarters, as  used by  the Company  in
computing  primary earnings  per share ("W").  The number  of outstanding common
shares and common share  equivalents described above  assumes the conversion  of
each share of Class B Common Stock into five shares of Class A Common Stock. The
5.66  multiplier is a constant which was  first included in the Formula in March
1976. The  Market Factor  is a  numerical factor  which is  intended to  reflect
existing  securities market conditions relevant to  the valuation of the Class A
Common Stock  and the  Class B  Common  Stock. The  Market Factor  is  generally
reviewed  quarterly by the  Board of Directors in  conjunction with an appraisal
which  is  prepared  by  an   independent  appraisal  firm  for  the   committee
administering  the Company's  qualified retirement  plans (the  "Committee") and
which is relied upon by the Committee and the Board of Directors. Subject to the
limitation set  forth above,  the Formula  Price of  the Class  A Common  Stock,
expressed as an equation, is as follows:

<TABLE>
<S>               <C>        <C>        <C>

                    W(1)                    W
</TABLE>

    The  Formula was adopted  in its present  form by the  Board of Directors on
March 23, 1984 and became effective with the March 30, 1984 price revision.  The
Board  of Directors has  reviewed the Market  Factor on a  quarterly basis since
that time. The Market Factor, as  determined by the Board of Directors,  remains
in effect until subsequently changed by the Board of Directors.

Stock will in the future provide returns comparable to historical rates.

    The  Board of Directors believes  that the Formula results  in a fair market
value for the Class A Common Stock  within a broad range of financial  criteria.
Other  than the quarterly review and possible modification of the Market Factor,
the Board of Directors will not change the Formula unless (i) in the good  faith
exercise  of  its fiduciary  duties and  after  consultation with  the Company's
independent accountants as  to whether the  change would result  in a charge  to
earnings  upon the  sale of Class  A Common Stock  or Class B  Common Stock, the
Board of Directors, including a majority of the directors who are not  employees
of  the Company, determines that the Formula  no longer results in a fair market
value for the Class A Common Stock or (ii) a change in the Formula or the method
of valuing the Class A Common Stock is required under applicable laws.

                                DIVIDEND POLICY

    The Company has  never declared or  paid any cash  dividends on its  capital
stock  and no cash dividends on the Class A Common Stock or Class B Common Stock
are contemplated in the foreseeable  future. The Company's present intention  is
to retain any future earnings for use in its business.

                                USE OF PROCEEDS

    The  shares of Class A Common Stock which  may be offered by the Company are
principally being offered to permit the  continued acquisition of shares by  the
Company's  employee benefit plans as described  herein and to permit the Company
to offer  shares  of Class  A  Common Stock  to  present and  future  employees,
consultants  and directors. The net proceeds to  be received by the Company from
the sale  of shares  of  Class A  Common Stock  offered  by the  Company,  after
deducting  expenses payable by the Company,  which are estimated to be $126,151,
will be  added to  the general  funds of  the Company  for working  capital  and
general corporate purposes. Currently, the Company has no specific plans for the
use  of such proceeds.  Approximately 2,000,000 of  the shares registered hereby
are offered by stockholders  (other than the  Selling Stockholders) pursuant  to
the  Limited Market and such sales may  be attributed to the Company for federal
securities law purposes.  The Company will  not receive any  portion of the  net
proceeds  from the sale of such shares or from the sale of shares by the Selling
Stockholders.

                             EMPLOYEE BENEFIT PLANS

    The Company  maintains  several employee  benefit  plans pursuant  to  which
certain  of the shares of Class A Common Stock being offered hereby may be sold.
The primary  purpose of  these plans  is to  motivate the  Company's  employees,
consultants  and directors  to contribute to  the growth and  development of the
Company by encouraging them to achieve  and surpass annual goals of the  Company
and

                                       11
<PAGE>
of  the operations for  which they are  responsible. The following  is a summary
description of  each of  these plans.  All capitalized  terms, unless  otherwise
defined  herein, have the meanings ascribed to them in the employee benefit plan
to which they relate.

PROFIT SHARING RETIREMENT PLAN II

    The Profit Sharing Retirement Plan II represents a consolidation,  effective
as  of January 1, 1992, of the former TSC Profit Sharing Retirement Plan and the
SAIC COMSYSTEMS  Profit Sharing  Retirement Plan  (together referred  to as  the
"Consolidated  Plans"  or Profit  Sharing Retirement  Plan  II). The  TSC Profit
Sharing Retirement  Plan  first became  effective  July  1, 1988  and  the  SAIC
COMSYSTEMS  Profit Sharing  Retirement Plan  first became  effective February 1,
1977. The following discussion includes, where applicable, a description of  the
Consolidated Plans relating to periods prior to January 1, 1992.

  ELIGIBILITY AND PARTICIPATION

    Generally,  all employees  of eligible  groups within  the Company  who have
attained the age  of 21,  completed 12 months  of employment  and completed  850
Hours  of  Service with  the Company  during one  of the  12-month computational
periods are eligible to participate as of the next semi-annual entry date. As of
December 31, 1993,  there were  approximately 2,200 participants  in the  Profit
Sharing Retirement Plan II.

  CONTRIBUTIONS, ALLOCATIONS AND FORFEITURES

    For  the  Plan  Year  ended  December  31,  1993,  the  Company  contributed
approximately $1,990,000 to the accounts  of participants in the Profit  Sharing
Retirement  Plan  II.  The  amount  of  the  Company's  annual  contribution  to
participants' accounts in the  Profit Sharing Retirement  Plan II is  determined
by,  and within the discretion of, the  Company's Board of Directors, subject to
certain limitations. See  "General Provisions of  the Profit Sharing  Retirement
Plan II, Employee Stock Ownership Plan and CODA." The Company's contribution may
be  paid in cash or such other property as the Board of Directors may determine.
The Company's contributions are made by  the due date (including extensions)  of
the  Company's federal income tax return  for the applicable year. The Company's
current practice has been to make pro-rata contributions quarterly.

    Company contributions to the Profit Sharing Retirement Plan II for each Plan
Year are allocated  to the accounts  of participants who  complete 850 Hours  of
Service during the Plan Year. The amount of Company contributions allocated to a
participant's  account for the Plan  Year is determined in  two steps. The first
allocation  is  based  on  the  ratio  which  a  participant's  Eligible  Excess
Compensation  (i.e., compensation  in excess of  the Social  Security Wage Base,
$60,600 for  1994)  for  the  Plan  Year bears  to  the  total  Eligible  Excess
Compensation  for  such Plan  Year  of all  participants  in the  Profit Sharing
Retirement Plan  II.  The  amount  to be  allocated  in  the  first  allocation,
expressed  as a percentage of Eligible Excess Compensation, shall not exceed the
lesser of  (i) 5.7%  or,  if greater,  the  rate of  tax  applicable as  of  the
beginning  of that Plan Year  under Section 3111(a) of  the Code attributable to
old age insurance  or (ii)  the percentage  allocated in  the second  allocation
(described  below) of the portion of compensation of participants which does not
exceed the Social Security Wage Base  for such Plan Year. The second  allocation
allocates contributions remaining after the first allocation to each participant
based  on the  ratio which each  participant's total compensation  for such Plan
Year bears to the total compensation paid to all participants for such year.

    Forfeitures, if any, of the nonvested portion of participants' accounts  are
allocated  to the accounts of remaining participants who are entitled to receive
an allocation of the  Company contribution for  the year in  the same manner  as
Company contributions for the year.

    Participants  in the Profit Sharing Retirement  Plan II are not permitted to
make voluntary contributions. Voluntary contributions made prior to January 1987
will continue  to  be  held in  the  Profit  Sharing Retirement  Plan  II  until
withdrawn or distributed.

                                       12

  INVESTMENT OF FUNDS

    The Committee is authorized to establish a choice of investment alternatives
within  the Trust Fund maintained  for the Profit Sharing  Retirement Plan II in
which Company contributions may be invested, provided that not more than 20%  of
each  Company contribution allocated to a  participant's account may be invested
in securities  of the  Company. Participants  may elect  at such  time, in  such
manner  and subject to such  restrictions as the Committee  may specify, to have
contributions  allocated   or  apportioned   among  the   different   investment
alternatives.  Separate accounts are established for each investment alternative
selected by a participant and each account is valued separately.

    The Committee, in its sole  discretion, may permit participants to  transfer
amounts  from  one  investment  alternative  to  one  or  more  other investment
alternatives at such time,  in such manner and  subject to such restrictions  as
the  Committee  may  specify.  Investments  in the  Company  Stock  Fund  may be
exchanged into other investment choices only on a Trade Date. However,  balances
from the Vanguard Group of Investment Companies ("Vanguard") investments may not
be  exchanged into the Company Stock Fund at  any time. It is the current policy
of the  Committee  to keep  all  amounts related  to  the Company's  Stock  Fund
invested  in Class A Common Stock, except  for estimated cash reserves which are
primarily used  to  provide  future  benefit  distributions,  future  investment
exchanges  and other  cash needs as  determined by the  Committee. Residual cash
remaining after accounting for estimated cash reserves generally will be used to
purchase Class A Common Stock. If at any given time cash reserves in the Company
Stock Fund are insufficient to  provide benefit distributions and/or  investment
exchanges,  shares held by the Company Stock Fund will be offered to the Company
for purchase. If  the Company  declines to  purchase the  shares, the  Committee
intends to offer the shares for sale in the Limited Market. Exchanges out of the
Company  Stock Fund may  be deferred until  such time, if  ever, that sufficient
cash is  available  to  make  required benefit  distributions  and  provide  for
investment   exchanges.  Accordingly,  investment   exchanges  of  participant's
investments held  in the  Company  Stock Fund  may  be restricted.  See  "Market
Information -- The Limited Market."

    The  Committee  has  established  a choice  of  investment  alternatives for
participants. The  alternatives consist  of  the Company  Stock Fund  and  seven
Vanguard   Mutual  Funds   managed  by   Vanguard,  located   in  Valley  Forge,
Pennsylvania, which are subject to the limitations described above.

    The following table summarizes,  as of the  dates indicated, the  investment
performance of the Company Stock Fund and of each of Vanguard's seven nationally
traded  mutual funds for the last five years. The summary is based on an initial
investment of $100 in each investment alternative.

  VESTING

    The  Profit Sharing Retirement  Plan II vesting  schedule currently provides
that a  participant's interest  does not  vest at  all prior  to the  time  such
participant is credited with three Years of Service, and thereafter vests at the
rate  of 25%  per Year  of Service  for years  three through  six, so  that each
participant's interest becomes  fully vested after  the participant is  credited
with  six Years of Service. Any accounts as of August 1, 1987 in the former SAIC
COMSYSTEMS Money Accumulation Pension Plan ("MAPP Subaccounts") which remain  in
the Profit Sharing Retirement Plan II are 100% vested.

    A participant's interest also becomes fully vested, notwithstanding the fact
that  he or she has not yet been credited with six Years of Service, at the time
of such participant's  attainment of the  age of 59  1/2, permanent  disability,
judicial  declaration of  mental incompetence  or death,  while employed  by the
Company.

                                       15
<PAGE>
  LOANS

    Loans  are  available from  the  Profit Sharing  Retirement  Plan II  to all
participants. Loans under all of  the Company's and its subsidiaries'  qualified
retirement  plans  have  a combined  maximum  limit of  $50,000  per participant
reduced by the excess  of the participant's  highest aggregate outstanding  loan
balance(s)  during  the  preceding  12-month  period  over  the  aggregate  loan
balance(s) outstanding on the date of a  new loan. Loans are further limited  to
50% of a participant's vested interest in his or her accounts which are eligible
to  receive a loan,  in all of  the Company's qualified  retirement plans (loans
from the Profit Sharing Retirement  Plan II may not  exceed the vested value  of
the assets in the Profit Sharing Retirement Plan II less vested amounts invested
in  the Company Stock Fund). Loans must  (i) bear a reasonable rate of interest,
(ii) be adequately secured,  (iii) state the  date upon which  the loan must  be
repaid,  which in any event may not exceed five years from the date on which the
loan is made,  unless the  proceeds are  used for  the purchase  of a  principal
residence, in which case repayment may not exceed 25 years and (iv) be amortized
with  level payments, made not less frequently  than quarterly, over the term of
the loan. The Committee currently requires that loans be repaid through  payroll
deductions.  The loan  documents provide  that 50%  of the  participant's vested
account balances in all of the Company's qualified retirement plans are security
for the loan, and the  Profit Sharing Retirement Plan II  (as well as the  other
Company  retirement plans in which  the participant has a  loan) therefore has a
lien against such balances. A loan will result in the withdrawal of the borrowed
amounts from the participant's interest in  the Funds against which the loan  is
made (other than the Company Stock Fund). Principal and interest payments on the
loan  are allocated to the account(s) of the borrowing participant in accordance
with the current investment choices of the participant.

  DISTRIBUTIONS AND WITHDRAWALS

    If a participant's employment  with the Company terminates  on or after  the
date  on which  the participant attains  the age  of 59 1/2,  the participant is
entitled to receive a single distribution of  his or her entire interest in  his
or  her  Profit  Sharing  Retirement  Plan II  account  as  soon  as practicable
following the date of  such termination. In the  event a participant dies  while
employed  by the Company, the Committee will direct the Trustee to make a single
distribution of the participant's entire interest  in his or her Profit  Sharing
Retirement  Plan II account to  the participant's spouse, or  if such spouse has
given proper consent  or if the  participant has no  spouse, to the  Beneficiary
designated  by the participant.  In the event the  Committee determines that the
participant has suffered a permanent  disability while employed by the  Company,
the  Committee will  direct the  Trustee to  make a  single distribution  of the
participant's entire interest in  his or her Profit  Sharing Retirement Plan  II
account to the disabled participant.

    If  a participant's  employment with  the Company  terminates other  than by
reason of  permanent  disability  or  death  prior to  the  date  on  which  the
participant  attains the age of 59 1/2, the participant's vested interest in his
or her Profit Sharing  Retirement Plan II  account generally will  be paid in  a
single  distribution. If the participant's vested interest in his or her account
is $3,500 or less, benefits are paid as soon as practicable after termination of
employment. If his or her vested interest  in such account is more than  $3,500,
the  participant may  elect to  receive distribution of  his or  her account (i)
approximately 120 days  after the  end of  the year in  which his  or her  fifth
consecutive  Break  in  Service  occurs,  (ii) any  time  following  his  or her
termination of employment and before five consecutive Breaks in Service or (iii)
at age 62.

    If a participant  who was only  partially vested  in his or  her account  is
reemployed  before  having five  consecutive Breaks  in Service,  he or  she may
reinstate his  or  her  account,  including  the  nonvested  portion  which  was
previously  forfeited, by repaying  the amount distributed to  him or her before
the earlier of (i) the date he or she incurs five consecutive Breaks in  Service
following the date of distribution or (ii) five years following reemployment.

    Distribution  of  MAPP  Subaccounts  are  subject  to  certain  requirements
regarding  joint  and  survivor  annuities  set  forth  in  the  Profit  Sharing
Retirement Plan II.

                                       16
<PAGE>
    All distributions, including withdrawals, from the Profit Sharing Retirement
Plan  II will be made  in cash, subject to  certain requirements regarding joint
and survivor annuities applicable to MAPP Subaccounts.

    A participant  in the  Profit  Sharing Retirement  Plan  II is  entitled  to
withdraw  amounts from  his or  her voluntary  contribution account,  subject to
reasonable Committee  restrictions  regarding  frequency  and  amounts  of  such
withdrawals.  All such withdrawals will be paid in a single distribution as soon
as administratively feasible.

    In the absence of  a qualified domestic relations  order to the contrary,  a
participant's  interest  in the  Profit Sharing  Retirement Plan  II may  not be
voluntarily or involuntarily assigned or hypothecated, except for the purpose of
qualified SAIC Retirement Program loans.

EMPLOYEE STOCK OWNERSHIP PLAN

    The Company's stock bonus  retirement plan became  effective on February  1,
1973  and was  approved by the  stockholders of  the Company at  the 1982 Annual
Meeting of Stockholders.  Effective January  1, 1985,  the plan  was amended  to
change  its  name to  the  Employee Stock  Ownership Plan  and  to enable  it to
purchase shares of Class  A Common Stock with  the proceeds of qualifying  loans
made  either to the  Company or to  the Employee Stock  Ownership Plan. To date,
this loan feature  has not been  utilized. In February  1990, the Company  Stock
Funds  within  the  Company's  Profit  Sharing  Retirement  Plan  and  the  CODA
(including the TRASOP Fund maintained within  the CODA) were transferred to  the
Employee  Stock  Ownership Plan  to enable  it to  qualify as  a "30%  ESOP" and
further the  Company's  goal  of  employee stock  ownership  by  increasing  the
percentage   of  the  Company's  Common  Stock  beneficially  owned  by  current
employees. In November 1992, the non-exchangeable Company Stock Fund within  the
CODA  was  transferred to  the Employee  Stock  Ownership Plan  to enable  it to
qualify as  a "30%  ESOP" in  connection with  an Offer  to Purchase  for  Cash,
pursuant  to which the Employee Stock  Ownership Plan acquired 700,444 shares of
Class A  Common  Stock  from  stockholders who  are  not  employees,  directors,
consultants  or members of their families  in a transaction designed to increase
the beneficial ownership  of current employees,  directors and consultants.  See
"Market Information--The Limited Market."

  ELIGIBILITY AND PARTICIPATION

    Generally,  all  employees who  have attained  the age  of 21,  completed 12
months of employment and completed 850 Hours of Service with the Company  during
one of the applicable 12-month computational periods are eligible to participate
as of the next semi-annual entry date, except employees who are eligible for the
SAIC  Profit Sharing Retirement Plan II and  other groups or units designated as
ineligible.  As  of   December  31,  1993,   there  were  approximately   15,000
participants in the Employee Stock Ownership Plan.

  CONTRIBUTIONS, ALLOCATIONS AND FORFEITURES

    For  the  Plan  Year  ended  December  31,  1993,  the  Company  contributed
approximately $15,096,000 to the accounts of participants in the Employee  Stock
Ownership Plan. The amount of the Company's annual contribution to participants'
accounts  in the Employee Stock Ownership Plan  is determined by, and within the
discretion of,  the Board  of  Directors, subject  to certain  limitations.  See
"General  Provisions of  the Profit Sharing  Retirement Plan  II, Employee Stock
Ownership Plan and CODA." Participants  may not make voluntary contributions  to
the  Employee Stock Ownership Plan. The  Company's contributions are made by the
due date (including extensions) of the  Company's federal income tax return  for
the  applicable year. The  Company's current practice has  been to make pro-rata
contributions quarterly.

    Company contributions to  the Employee  Stock Ownership Plan  for each  Plan
Year  are allocated to  the accounts of  participants who complete  850 Hours of
Service during the Plan Year in the ratio which each such participant's eligible
compensation bears to the total eligible compensation of all such  participants.
Forfeitures,  if  any,  of  the nonvested  portion  of  terminated participants'
accounts are

                                       17
<PAGE>
allocated to the accounts of remaining participants who are entitled to  receive
an  allocation of  the Company  contribution. Forfeitures  are allocated  in the
ratio which each such remaining participant's eligible compensation bears to the
total eligible compensation of all such remaining participants.

  INVESTMENT OF FUNDS

    Although it is  generally intended  that the  assets of  the Employee  Stock
Ownership  Plan will  be held  in a Company  Stock Fund  consisting primarily of
securities of the Company, the Employee Stock Ownership Plan and/or such Company
Stock Fund may hold other assets which may consist of cash, qualifying  employer
real  property or qualifying employer securities  within the meaning of Sections
407(d)(4) and (5)  of the Employee  Retirement Income Security  Act of 1974,  as
amended  ("ERISA"), or  other property.  The exact number  of shares  of Class A
Common Stock, if  any, which may  be purchased  by the Trustee  of the  Employee
Stock Ownership Plan in the future will depend on various factors, including any
modifications to the Employee Stock Ownership Plan adopted either in response to
changes  or modifications  in the  laws and  regulations governing  the Employee
Stock Ownership Plan or at the discretion of the Company's management.

    With respect to those Company Stock Funds transferred to the Employee  Stock
Ownership  Plan  in February  1990 as  to  which participants  had the  right to
exchange into  other  investment  choices under  the  Company's  Profit  Sharing
Retirement  Plan or CODA, as applicable,  the investment choices available under
the latter plans  (see "Employee Benefit  Plans--Profit Sharing Retirement  Plan
II--  Investment  of  Funds")  are  made  available  within  the  Employee Stock
Ownership Plan. In addition,  participants who have attained  the age of 55  and
have  ten or more years of participation  are entitled, pursuant to the terms of
the Employee  Stock  Ownership Plan  and  Committee procedures,  to  exchange  a
percentage  of their balances in  the Company Stock Fund  into the same Vanguard
investment alternatives as  are available  under the  Profit Sharing  Retirement
Plan II.

    The  Committee, in its sole discretion,  may permit participants to transfer
amounts from  one  investment  alternative  to  one  or  more  other  investment
alternatives  at such time, in  such manner and subject  to such restrictions as
the Committee  may  specify.  Investments  in the  Company  Stock  Fund  may  be
exchanged  into other investment choices only on a Trade Date. However, balances
from other Vanguard  investments may  not be  exchanged into  the Company  Stock
Fund.  Company contributions  directed to the  Company Stock  Fund are initially
utilized as cash  reserves to  provide benefit  distributions and/or  investment
exchanges. It is the current policy of the Committee to keep all amounts related
to  the  Company's Stock  Fund  invested in  Class  A Common  Stock,  except for
estimated cash  reserves which  are  primarily used  to provide  future  benefit
distributions, future investment exchanges and other cash needs as determined by
the  Committee.  Residual cash  remaining  after accounting  for  estimated cash
reserves will generally  be used to  purchase Class  A Common Stock.  If at  any
given  time cash reserves in the Company  Stock Fund are insufficient to provide
benefit distributions and/or  investment exchanges, shares  held by the  Company
Stock  Fund will be offered to the Company for purchase. If the Company declines
to purchase the shares, the  Committee intends to offer  the shares for sale  in
the  Limited Market.  Exchanges out  of the Company  Stock Fund  may be deferred
until such time,  if ever, that  sufficient cash is  available to make  required
benefit   distributions  and  provide  for  investment  exchanges.  Accordingly,
investment exchanges of participant's investments held in the Company Stock Fund
may be restricted. See "Market Information--The Limited Market."

  VESTING

    The Employee Stock Ownership Plan vesting schedule currently provides that a
participant's interest does not vest at  all prior to the time such  participant
is credited with three Years of Service, and thereafter vests at the rate of 25%
per  Year of  Service for  years three through  six, so  that each participant's
interest becomes fully vested after the  participant is credited with six  Years
of  Service. A participant's interest also becomes fully vested, notwithstanding
the fact  that the  participant has  not yet  been credited  with six  Years  of
Service,   at  the  time  of  such   participant's  attainment  of  the  age  of

                                       18
<PAGE>
59 1/2, permanent  disability, judicial  declaration of  mental incompetence  or
death,  while employed  by the Company.  A participant's interest  in the TRASOP
Fund or in funds transferred from the CODA are 100% vested at all times.

  LOANS

    Loans  are  available  from  the  Employee  Stock  Ownership  Plan  to   all
participants.  Loans under all of the  Company's and its subsidiaries' qualified
retirement plans  have  a combined  maximum  limit of  $50,000  per  participant
reduced  by the excess  of the participant's  highest aggregate outstanding loan
balance(s)  during  the  preceding  12-month  period  over  the  aggregate  loan
balance(s)  outstanding on the date of a  new loan. Loans are further limited to
50% of  a participant's  vested  interest in  his or  her  accounts in  all  the
Company's  qualified  retirement  plans  (those loans  from  the  Employee Stock
Ownership Plan may not exceed  the vested value of  the amounts in the  Employee
Stock  Ownership Plan  less vested  amounts invested  in the  Company Stock Fund
within the Plan). Loans  must (i) bear  a reasonable rate  of interest, (ii)  be
adequately  secured, (iii) state  the date upon  which the loan  must be repaid,
which in any event may not exceed  five years, unless the proceeds are used  for
the purchase of a principal residence, in which case repayment may not exceed 25
years  and (iv) be amortized with level  payments, made not less frequently than
quarterly, over the  term of  the loan.  The Committee  currently requires  that
loans  be repaid through payroll deductions. The loan documents provide that 50%
of the participant's  vested account  balances in all  the Company's  retirement
plans  are security for the loan, and the Employee Stock Ownership Plan (as well
as the other  Company retirement  plans in which  the participant  has a  loan),
therefore,  has a lien against such balances. A loan will result in a withdrawal
of the borrowed  amounts from the  participant's interest in  the Funds  against
which  the  loan is  made (other  than  the Company  Stock Fund).  Principal and
interest payments on the loan are  allocated to the account(s) of the  borrowing
participant   in  accordance  with   the  current  investment   choices  of  the
participant.

  DISTRIBUTIONS AND WITHDRAWALS

    If a participant's employment  with the Company terminates  on or after  the
date  on which  the participant attains  the age  of 59 1/2,  the participant is
entitled to receive a single distribution of  his or her entire interest in  his
or  her Employee Stock  Ownership Plan account as  soon as practicable following
the date of such termination. In the event a participant dies while employed  by
the Company, the Committee will direct the Trustee to make a single distribution
of the participant's entire interest in his or her Employee Stock Ownership Plan
account  to the participant's spouse or if  such spouse has given proper consent
or if  the  participant has  no  spouse to  the  Beneficiary designated  by  the
participant.  In the  event the  Committee determines  that the  participant has
suffered a permanent  disability while  employed by the  Company, the  Committee
will  direct  the Trustee  to make  a single  distribution of  the participant's
entire interest  in his  or her  Employee Stock  Ownership Plan  account to  the
disabled participant.

    If  a participant's  employment with the  Company terminates,  other than by
reason of  permanent  disability  or death,  prior  to  the date  on  which  the
participant  attains the age of 59 1/2, the participant's vested interest in his
or her Employee Stock Ownership Plan account generally will be paid in cash in a
single distribution. If the participant's vested interest in his or her  account
is $3,500 or less, benefits are paid as soon as practicable after termination of
employment.  If his or her  vested interest in the  account is more than $3,500,
the participant may elect  to receive a  distribution of his  or her account  in
cash  (i) approximately 120 days after  the end of the year  in which his or her
fifth consecutive Break in  Service occurs, (ii) any  time following his or  her
termination of employment and before five consecutive Breaks in Service or (iii)
at age 62.

    A  participant may elect  to receive a  distribution in the  form of Class A
Common Stock (and Class B  Common Stock, where applicable)  in lieu of the  cash
distribution alternatives described above. Such distribution will be made within
120  days of  the participant's normal  retirement age  (age 59 1/2)  or date of
actual  retirement,  if  later.  However,  for  employees  whose  employment  is
terminated after

                                       19
<PAGE>
February  9, 1990,  with respect  to any  Class A  Common Stock  purchased after
December 31, 1986, a participant electing to receive Common Stock shall  receive
the  payments in five  annual installments commencing within  one year after the
fifth Plan Year following termination of employment.

    If a participant  who was only  partially vested  in his or  her account  is
reemployed  before  having five  consecutive Breaks  in Service,  he or  she may
reinstate his  or  her  account,  including  the  nonvested  portion  which  was
previously  forfeited, by repaying  the amount distributed to  him or her before
the earlier of (i) the date he or she incurs five consecutive Breaks in  Service
following the date of distribution or (ii) five years following reemployment.

    All  distributions from  the Employee Stock  Ownership Plan will  be made in
cash, except as noted above. In those instances in which Class A Common Stock or
Class  B  Common  Stock  is  distributed  to  participants  in  lieu  of   cash,
participants  cannot be assured that  they will be able  to sell their shares in
any one quarterly  Trade Date  or over  any specific period  of time  or at  the
Formula  Price at the time of such sale. Accordingly, a participant's ability to
sell shares of Class A Common Stock  or Class B Common Stock distributed out  of
the  Employee Stock Ownership  Plan could be  adversely affected by  any lack of
liquidity in the Limited Market. See "Market Information--The Limited Market."

    All distributions of  shares of  Class A Common  Stock (and  Class B  Common
Stock where applicable) out of the Employee Stock Ownership Plan will be subject
to  the following conditions imposed by the Employee Stock Ownership Plan and/or
the Company's Certificate of Incorporation:

        (a) Such shares  will be  subject to  a right  of first  refusal by  the
    Company  and the Employee Stock  Ownership Plan, but will  not be subject to
    the  Company's  right  of  repurchase  upon  termination  of  employment  or
    affiliation.  See "Description of Capital Stock--Common Stock-- Restrictions
    on Class A Common Stock."

        (b) In the event that such shares, at the time they are distributed  out
    of  the Employee Stock Ownership Plan, are not "Readily Tradeable Stock" (as
    that term is defined under Treasury Regulation Section  54.4975-7(b)(1)(iv))
    or  are subject  to a  "Trading Limitation" (as  that term  is defined under
    Treasury Regulation Section 54.4975-7(b)(10)), then they will be subject  to
    a  "put option" which gives  the holder of such  shares the right to require
    the Company to purchase all or a portion of such shares at their fair market
    value during two  limited time periods.  The first of  these periods is  the
    60-day  period following the date on which the shares are distributed out of
    the Employee Stock  Ownership Plan and  the second of  these periods is  the
    60-day  period following notification by the Company of the valuation of the
    Class A Common Stock and Class B  Common Stock as soon as practicable  after
    the beginning of the Plan Year commencing after such distribution.

    Accounts  transferred from the CODA or Profit Sharing Retirement Plan retain
the distribution options available under the  terms of the plan from which  they
were transferred.

    Participants  are not permitted to make withdrawals under the Employee Stock
Ownership  Plan  prior  to  termination   of  employment  except  for   hardship
withdrawals  from the account  transferred to the  Employee Stock Ownership Plan
from  the   CODA.   See   "Employee   Benefit   Plans--CODA--Distributions   and
Withdrawals."  In the  absence of  a qualified  domestic relations  order to the
contrary, a participant's interest in the Employee Stock Ownership Plan may  not
be voluntarily or involuntarily assigned or hypothecated, except for the purpose
of qualified SAIC retirement program loans.

CODA

    The  CODA  became effective  on  January 1,  1983  and was  approved  by the
stockholders of the Company at the 1983 Annual Meeting of Stockholders.

  ELIGIBILITY AND PARTICIPATION

    Generally,  all  employees  (as  defined  in  the  CODA)  are  eligible   to
participate  in the  CODA upon  commencing employment,  except for  employees in
groups or units designated  as ineligible. As of  December 31, 1993, there  were
approximately 17,400 participants in the CODA.

                                       20
<PAGE>
  CONTRIBUTIONS AND ALLOCATIONS

    The  CODA  permits  a  participant  to elect  to  defer  a  portion  of such
participant's compensation for the  Plan Year and to  have such deferred  amount
contributed  directly by the Company to  the participant's CODA account. Amounts
deferred by  participants, including  rollovers from  qualified plans,  totalled
approximately  $39,462,000 for the Plan Year  ended December 31, 1993. Under the
terms of the  CODA, deferred amounts  are treated as  contributions made by  the
Company.  The maximum  amount of  compensation that  a participant  may elect to
defer is determined by the  Committee, but in no  event may the deferral  exceed
$7,000  per  year (adjusted  for cost-of-living  under  rules prescribed  by the
Secretary of the Treasury). For 1994,  the limitation is $9,240. In addition  to
amounts deferred by participants, the Company may, but is not obligated to, make
a  matching contribution  to the  CODA accounts  of those  participants who have
elected to  defer a  portion of  their  compensation equal  to a  percentage  or
percentages  of the amounts which such  participants have elected to defer. This
Company matching  contribution  is  allocated  to the  CODA  accounts  of  those
participants  who are not employees of a  group or unit designated as ineligible
to receive a matching contribution  and who have elected  to defer a portion  of
their  compensation.  For the  Plan Year  ended December  31, 1993,  the Company
contributed 30% of  the first  $2,000 of a  participant's compensation  deferred
under  the CODA and 15% of such  deferred compensation above $2,000. The Company
provides no  matching contribution  on  amounts deferred  in  excess of  10%  of
compensation.  The aggregate amount of matching contributions contributed to the
CODA on behalf of all participants for the Plan Year ended December 31, 1993 was
approximately $7,674,000. The Company may also make additional contributions  to
the  CODA in order to comply with Section  401(k) of the Code. For the Plan Year
ended December 31,  1993, the Company  was not required  to make any  additional
Company  contributions  to the  Deferred Fund  to  enable the  plan to  meet the
Section 401(k) discrimination test.  The Company's contribution  to the CODA  is
paid  in cash unless the Board of  Directors determines to make the contribution
in shares of Class A Common Stock or another form.

    Company contributions  to the  CODA  are made  by  the due  date  (including
extensions)  for the Company's federal income tax return for the applicable year
except contributions resulting from amounts deferred by participants, which must
be made within  30 days of  deferral. The  Company's practice has  been to  make
matching   contributions  quarterly  based   on  current  participant  bi-weekly
deferrals. Any additional Company contribution,  if required, is made after  the
end of the Plan Year.

    A   participant's  elective  deferrals  to  CODA  will  reduce  his  or  her
compensation,  on  a   dollar-for-dollar  basis,  for   purposes  of   receiving
allocations  under  the Company's  Profit  Sharing Retirement  Plan,  the Profit
Sharing Retirement Plan II and the Employee Stock Ownership Plan, as applicable.

    An Eligible Employee may transfer to the trust fund maintained for the  CODA
a  rollover  contribution from  another  qualified retirement  plan  pursuant to
applicable regulations and Committee procedures.  A participant in the CODA  who
has  made a  deferral election  may terminate or  alter the  rate of  his or her
deferrals at any time under the terms of the CODA.

  INVESTMENT OF FUNDS

    The Committee is authorized to establish a choice of investment alternatives
including securities of the Company, in which Company contributions to the  CODA
(including  that portion of compensation which  participants elect to defer) may
be invested. The investment alternatives currently available to participants  in
the  CODA are the same as those  available to participants in the Profit Sharing
Retirement Plan II,  except that  under the terms  of the  CODA a  participant's
entire  interest in his or her CODA account may be invested in the Company Stock
Fund.  See   "Employee   Benefit   Plans--  Profit   Sharing   Retirement   Plan
II--Investment of Funds." The Company's matching contributions for the Plan Year
ended  December 31, 1993 were (and the  matching contributions for the Plan Year
ending December 31, 1994 are currently intended to be) invested in the Company's
Stock Fund,  which contributions  may not  be exchanged  for another  investment
alternative.  Participants may elect at such time, in such manner and subject to
such restrictions as the Committee may specify, to have contributions  allocated
or  apportioned  among  the  different  investment  alternatives.  Separate CODA

                                       21
<PAGE>
accounts  are  established  for  each  investment  alternative  selected  by   a
participant  and each such  account is valued separately.  The Committee, in its
sole discretion, may permit participants to transfer amounts from one investment
alternative to one or more other  investment alternatives at such time, in  such
manner and subject to such restrictions as the Committee may specify.

    Investments  in  the Company  Stock  Fund (other  than  the non-exchangeable
contribution described in the preceding  paragraph) may be exchanged into  other
investment  choices only on a Trade Date. Balances from Vanguard investments may
not be exchanged into the  Company Stock Fund. It is  the current policy of  the
Committee  to keep all amounts  related to the Company's  Stock Fund invested in
Class A Common  Stock, except for  estimated cash reserves  which are  primarily
used  to provide future  benefit distributions, future  investment exchanges and
other cash needs as determined by  the Committee. Residual cash remaining  after
accounting  for estimated cash reserves generally will be used to purchase Class
A Common Stock. If cash reserves in  the Company Stock Fund are insufficient  at
any  given time  to provide  benefit distributions  and/or investment exchanges,
shares held  by the  Company  Stock Fund  will be  offered  to the  Company  for
purchase.  If the Company declines to purchase the shares, the Committee intends
to offer the shares for sale in the Limited Market. Exchanges out of the Company
Stock Fund may be  deferred until such  time, if ever,  that sufficient cash  is
available  to  make required  benefit distributions  and provide  for investment
exchanges. Accordingly, investment exchanges  of participants' investments  held
in  the  Company  Stock Fund  may  be restricted.  See  "Market Information--The
Limited Market."

  VESTING

    Under the CODA as  currently in effect, each  participant is, at all  times,
100% vested in his or her CODA account.

  LOANS

    Loans  are available from the CODA  account to all participants. Loans under
all of the  Company's and its  subsidiaries' qualified retirement  plans have  a
combined  maximum limit of $50,000 per participant  reduced by the excess of the
participant's highest aggregate outstanding loan balance(s) during the preceding
12-month period over the aggregate loan balance(s) outstanding on the date of  a
new loan. Loans are further limited to 50% of a participant's vested interest in
his or her accounts which are eligible to receive a loan in all of the Company's
qualified  retirement plans  (these loans  from CODA  may not  exceed the vested
value in the CODA less vested amounts invested in the Company Stock Fund). Loans
must (i) bear a reasonable rate  of interest, (ii) be adequately secured,  (iii)
state  the date upon which the  loan must be repaid, which  in any event may not
exceed five years from the date on  which the loan is made, unless the  proceeds
are  used for the purchase of a principal residence, in which case repayment may
not exceed 25 years  and (iv) be  amortized with level  payments, made not  less
frequently  than quarterly, over  the term of the  loan. The Committee currently
requires that loans  be repaid  through payroll deductions.  The loan  documents
provide  that 50%  of the  participant's vested account  balances in  all of the
Company's qualified retirement plans are security for the loan and the CODA  (as
well as the other Company retirement plans in which the participant has a loan),
therefore,  has a lien against such balances. A loan will result in a withdrawal
of the borrowed  amounts from the  participant's interest in  the Funds  against
which  the  loan  is made.  Principal  and  interest payments  on  the  loan are
allocated to the account(s) of the borrowing participant in accordance with  the
current investment choices of the participant.

  DISTRIBUTIONS AND WITHDRAWALS

    If  a participant's employment  with the Company terminates  on or after the
date on which  the participant attains  the age  of 59 1/2,  the participant  is
entitled  to receive a single distribution of  his or her entire interest in his
or her  CODA  account  as  soon  as  practicable  following  the  date  of  such
termination.  In the event a participant dies while employed by the Company, the
Committee will  direct  the  Trustee  to  make  a  single  distribution  of  the
participant's  entire interest in  his or her CODA  account to the participant's
spouse. Alternatively,  if  such spouse  has  given  proper consent  or  if  the
participant  has no  spouse, the  Committee will  direct the  Trustee to  make a
single distribution of the

                                       22
<PAGE>
deceased participant's  entire interest  to the  Beneficiary designated  by  the
participant.  In the  event the  Committee determines  that the  participant has
suffered a permanent  disability while  employed by the  Company, the  Committee
will  direct  the Trustee  to make  a single  distribution of  the participant's
entire interest in his or her CODA account to the disabled participant.

    If a participant's  employment with  the Company terminates,  other than  by
reason  of  permanent  disability or  death,  prior  to the  date  on  which the
participant attains the age of 59 1/2, the participant's vested interest in  his
or  her CODA account generally will be paid  in a single distribution as soon as
practicable following  the  date of  such  termination.  If his  or  her  vested
interest  is more than $3,500, the participant may elect to receive distribution
of his or her account  (i) approximately 120 days after  the end of the year  in
which  his  or her  fifth consecutive  Break  in Service  occurs, (ii)  any time
following his  or her  termination  of employment  and before  five  consecutive
Breaks in Service or (iii) at age 62.

    Except in the case of qualifying hardship, no withdrawals may be made from a
participant's  CODA account prior to his or her termination of employment unless
and until he or she attains the  age of 59 1/2. Any withdrawals made  thereafter
may  be made only once in each Plan Year. In the absence of a qualified domestic
relations order to the contrary, a participant's interest in the CODA may not be
voluntarily or involuntarily assigned or hypothecated, except for the purpose of
qualified  SAIC  retirement  program   loans.  The  Committee  has   established
procedures  for  hardship  withdrawals including  (i)  definition  of qualifying
hardships, (ii) requirements for having first withdrawn all voluntary  after-tax
contributions  from any other  Company retirement plans  and having received the
maximum loans available under  such plans and (iii)  requirement for a  12-month
suspension  from  making elective  deferrals  into CODA  following  the hardship
withdrawal.

    All distributions, including withdrawals, from the CODA are paid in cash.

GENERAL PROVISIONS OF THE PROFIT SHARING RETIREMENT PLAN II, EMPLOYEE STOCK
OWNERSHIP PLAN AND CODA

    The Profit Sharing  Retirement Plan  II, Employee Stock  Ownership Plan  and
CODA (collectively, the "Plans") each contain the following provisions:

  CONTRIBUTION LIMITATIONS

    The maximum contribution for any Plan Year which the Company may make to all
Plans for the benefit of a participant (including contributions to the CODA as a
result  of salary deferral elections by participants), plus forfeitures, may not
exceed the lesser of (i) $30,000 or (ii) 25% of the participant's compensation.

  ADMINISTRATION

    The Plans are administered by the Committee, whose members are appointed  by
and  serve at the discretion of the Company's Board of Directors. The members of
the Committee receive no  compensation from the Plans  for services rendered  in
connection  therewith. The current members of  the Committee are R.E. Bernstein,
S.J. Dalich (Ex-Officio),  J. Collymore,  W.M. Layson, L.O.  Louden, A.H.  Park,
J.M.  Preimesberger, W. Reed, W.A. Roper, Jr., M.W. Tobriner (Chairman) and J.P.
Walkush. The address of each  such person is Science Applications  International
Corporation,  10260 Campus Point Drive, San  Diego, CA 92121, except for Messrs.
Layson and Tobriner each of whom's address is Science Applications International
Corporation, 1710  Goodridge Drive,  McLean, VA  22102 and  Ms. Collymore  whose
address  is  Science  Applications  International  Corporation,  10770 Wateridge
Circle, San Diego, CA 92121.

    The Committee has the power to supervise administration and control of  each
Plan's  operations, including the power and  authority to (i) allocate fiduciary
responsibilities,  other  than   trustee  responsibilities,   among  the   Named
Fiduciaries, (ii) designate agents to carry out responsibilities relating to the
Plan,  other  than fiduciary  responsibilities,  (iii) employ  legal, actuarial,
medical, accounting, programming and other assistance as the Committee may  deem
appropriate  in carrying out the Plan,  (iv) establish rules and regulations for
the conduct of the Committee's business and the administration of the Plan,  (v)
administer,  interpret,  construe and  apply  the Plan  and  determine questions

                                       23
<PAGE>
relating to eligibility, the amount of any participant's service and the  amount
of  benefits to which any participant or beneficiary is entitled, (vi) determine
the manner  in which  Plan assets  are disbursed  and (vii)  direct the  Trustee
regarding  investment of Plan assets, subject  to the directions of participants
when provided in the Plans.

  PASS-THROUGH VOTING AND TENDERING OF CLASS A COMMON STOCK AND CLASS B COMMON
  STOCK

    Each participant in the  Plans has the  right to instruct  the Trustee on  a
confidential  basis as to how  to vote his or  her proportionate interest in all
shares of Class A Common Stock and/or  Class B Common Stock held in the  various
Plans.  The  Plan documents  provide that  the Trustee  will vote  all allocated
shares held in the Plans as to which no voting instructions are received (except
for shares held  in the  TRASOP Fund accounts  of participants  in the  Employee
Stock  Ownership Plan), together with all  unallocated shares held in the Plans,
in the same  proportion, on a  Plan-by-Plan basis, as  the allocated shares  for
which  voting  instructions have  been received  are voted.  Shares held  in the
TRASOP Fund accounts, as to which  no voting instructions from participants  are
received,  will not be voted by the Trustee. The Committee is required to notify
participants of  their pass  through  voting rights  prior  to each  meeting  of
stockholders.

    In  the event of  a tender or  exchange offer for  the Company's securities,
each participant in the Plans has  the right, under current Plan procedures,  to
instruct  the Trustee on a confidential basis as  to whether or not to tender or
exchange his or her proportionate interest in all shares of Class A Common Stock
and/or Class  B Common  Stock held  in  the various  Plans. The  Plan  documents
provide  that the Trustee will not tender  or exchange any allocated shares with
respect to which no instructions are received from participants. Shares held  in
the Plans which have not yet been allocated to the accounts of participants will
be  tendered or exchanged by  the Trustee, on a  Plan-by-Plan basis, in the same
proportion as the allocated shares held in each Plan are tendered or exchanged.

    The Trustee's duties  with respect to  voting and tendering  of Class A  and
Class  B Common Stock are  governed by the fiduciary  provisions of ERISA. These
fiduciary provisions of  ERISA may  require, in  certain limited  circumstances,
that  the Trustee override the votes, or  decisions whether or not to tender, of
participants with respect to Class A or  Class B Common Stock and to  determine,
in  the Trustee's  best judgment, how  to vote the  shares or whether  or not to
tender the shares.

  TRUSTEE

    State Street Bank and  Trust Company of North  Quincy, Massachusetts is  the
Trustee under each of the Plans.

    Generally,  the  Trustee  has  all  the  rights  afforded  a  trustee  under
applicable law, although the Trustee generally may exercise those rights only at
the direction of the Committee. Subject  to this limitation and those set  forth
in  the Plans and master trust agreement,  the Trustee's rights include, but are
not limited to,  the right  to (i)  invest and reinvest  the funds  held in  the
Plans'  trust  in  any investment  of  any kind,  including  qualifying employer
securities and qualifying employer real property as such investments are defined
in Section  407(d)  of  ERISA,  and contracts  issued  by  insurance  companies,
including  contracts under  which the insurance  company holds Plan  assets in a
separate account  or  commingles  separate accounts  managed  by  the  insurance
company,  (ii) retain  or sell  the securities  and other  property held  in the
Plans' trust, (iii) consent  or participate in any  reorganization or merger  in
regard to any corporation whose securities are held in the Plans' trust (subject
in  the  case  of  the Company's  securities,  generally,  to  the participants'
pass-through voting rights and right to instruct  the Trustee in the event of  a
tender  or exchange offer) and to pay calls or assessments imposed on the holder
thereof and to consent to any contract,  lease, mortgage or purchase or sale  of
any  property between such corporation and  any other parties, (iv) exercise all
the rights of the holder of any security held in the Plans' trust, including the
right to vote such securities (subject, in the case of the Company's securities,
generally, to  the  participants'  pass-through  voting  rights),  convert  such
securities  into other  securities, acquire  additional securities  and exchange
such securities, (v) vote

                                       24
<PAGE>
proxies and  exercise any  other similar  rights of  ownership, subject  to  the
Committee's  right  to  instruct  the  Trustee  as  to  how  (or  the  method of
determining how) the proxies should be voted or such rights should be  exercised
and  (vi)  lend to  participants  in the  Plans  such amounts  as  the Committee
directs.

    The  Trustee's  compensation  and  all   other  expenses  incurred  in   the
establishment,  administration  and  operation of  the  Plans are  borne  by the
respective Plans  unless the  Company  elects to  pay  such expenses.  Costs  or
expenses  which are particular to  a specific asset or  group of assets (such as
interest and normal brokerage and  other similar charges incurred in  connection
with  the  purchase  of  securities  by the  Plans'  trust)  are  chargeable and
allocable to the participants' accounts  to which such securities are  allocated
in a manner determined by the Committee.

  ADMINISTRATIVE AND CUSTODIAL SERVICES

    The  Company  has entered  into  an administrative  services  agreement with
Vanguard, pursuant to which Vanguard performs specified administrative  services
for  the Plans, principally related  to accounting and recordkeeping. Vanguard's
fees for these administrative services are borne by the respective Plans.

  ACCOUNT STATEMENTS

    Each participant is furnished with a statement of his or her accounts in the
respective Plans, as of the end of each calendar quarter.

  AMENDMENT AND TERMINATION

    The Company has reserved the  right to amend each of  the Plans at any  time
and  for any reason,  except that no such  amendment may have  the effect of (i)
generally causing any assets of the Plans' trusts to be used for or diverted  to
any   purpose  other   than  providing   benefits  to   participants  and  their
beneficiaries and  defraying  expenses of  the  Plans, except  as  permitted  by
applicable  law, (ii) depriving any participant or beneficiary, on a retroactive
basis, of  any  benefit  to which  they  would  otherwise be  entitled  had  the
participant's  employment with the  Company terminated immediately  prior to the
amendment or (iii) increasing the  liabilities or responsibilities of a  Trustee
or an Investment Manager without its written consent.

    The Company has also retained the right to terminate any of the Plans at any
time  and for any reason and, specifically, in the event the Company merges into
or with any other corporation and, as the result of which, the Company ceases to
exist as an entity.  In addition, the Company  may discontinue contributions  to
the  Plans; provided,  however, that  any such  discontinuation of contributions
shall not automatically terminate the Plans as to funds and assets then held  by
the Trustee.

  ERISA

    Each of the Plans is subject to the provisions of ERISA, including reporting
and  disclosure obligations, fiduciary standards, and the prohibited transaction
rules of Title I thereof. Since each of the Plans is an individual account  plan
under  ERISA, none of the  Plans are subject to  the jurisdiction of the Pension
Benefit Guaranty Corporation ("PBGC")  under Title IV of  ERISA and none of  the
Plans' benefits are guaranteed by the PBGC.

  FEDERAL INCOME TAX CONSEQUENCES

    Each   of  the  Plans  is  qualified  under  Section  401(a)  of  the  Code.
Qualification of the Plans  under Section 401(a) of  the Code has the  following
federal income tax consequences:

        (a)  A participant will not be subject  to federal income tax on Company
    contributions to the Plans at the time such contributions are made.

        (b) A  participant will  not be  subject to  federal income  tax on  any
    income or appreciation with respect to such participant's accounts under the
    Plans  until  distributions  are  made  (or  deemed  to  be  made)  to  such
    participant.

                                       25
<PAGE>
        (c) A  participant  and the  Company  will  not be  subject  to  federal
    employment  taxes on Company contributions to the Plans, except as set forth
    below with respect to certain Company contributions to the CODA.

        (d) The  Plans  will  not  be  subject to  federal  income  tax  on  the
    contributions  to them  by the  Company and will  not be  subject to federal
    income tax on any of their income or realized gains, assuming that the Plans
    do not realize any unrelated business taxable income.

        (e) Participation in  the Plans  will preclude or  restrict an  employee
    from  making deductible  contributions to  an Individual  Retirement Account
    ("IRA"), depending  on  the employee's  marital  status and  adjusted  gross
    income  ("AGI") for the year. If an employee or his or her spouse is covered
    by an employer-maintained retirement plan (such as any of the Plans), an IRA
    deduction is  available only  if the  participant's AGI  does not  exceed  a
    phase-out  level. For  married couples, the  phase-out of  the IRA deduction
    begins at $40,000 of AGI and there is no deduction if the participant's  AGI
    exceeds  $50,000. The phase-out  for single employees  is $25,000/$35,000 of
    AGI. For AGI in the phase-out range,  the IRA deduction limit is reduced  by
    the  ratio of AGI in excess of  $40,000 or $25,000, whichever is applicable,
    to $10,000.  AGI is  determined  before any  IRA  deduction, but  after  any
    elective  deferrals to  the CODA.  To the extent  that the  IRA deduction is
    limited  under  these  provisions,  a  non-deductible  IRA  contribution  is
    permitted  (in an amount  equivalent to the reduction  in the deductible IRA
    amount).

        (f) Subject to the contribution limitations contained in the Plans,  the
    Company  will be able  to deduct the  amounts that it  contributes under the
    Plans, with the amount  of such deduction generally  equaling the amount  of
    the contributions.

        (g)  Distributions from the Plans will  be subject to federal income tax
    under special,  complex rules  that apply  generally to  distributions  from
    tax-qualified  retirement plans. In general,  a single distribution from any
    of the Plans  will be taxable  in the  year of receipt  at regular  ordinary
    income  rates  (on the  full amount  of the  distribution, exclusive  of the
    amount of the participant's voluntary, non-deductible contributions made  to
    those  Plans  which  previously  permitted  such  contributions)  unless the
    distributee is eligible for and elects  (i) to make a qualifying  "rollover"
    of  the amount distributed  to an IRA  or another qualified  plan or (ii) to
    utilize  10-year  averaging,  5-year  averaging  or  partial  capital  gains
    taxation  of  the  distribution.  However,  the  tax  on  any  portion  of a
    qualifying  lump   sum   distribution   represented   by   "net   unrealized
    appreciation"  in  Class A  or  Class B  Common  Stock distributed  shall be
    deferred until  a subsequent  sale  or taxable  disposition of  the  shares,
    unless the distributee elects not to have this deferral apply.

        A  "lump sum distribution," for purposes  of eligibility for deferral of
    tax on net  unrealized appreciation,  is defined  as a  distribution of  the
    employee's entire vested interest under the Plan within one taxable year (i)
    on  account of the  participant's death or other  separation from service or
    (ii) after the  participant has attained  age 59 1/2.  For purposes of  this
    definition,  distributions from the CODA, the Profit Sharing Retirement Plan
    and the Profit Sharing Retirement Plan II must be aggregated. For a lump sum
    distribution to be eligible for 5-year averaging, the participant also  must
    have  been a participant in the Plan from which the distribution is made for
    at least five years prior to the year of distribution and must have attained
    age 59  1/2when the  distribution is  received. Under  a special  transition
    rule, an individual who had attained age 50 on January 1, 1986 and who would
    otherwise  be entitled to elect 5-year  averaging (without regard to the age
    59 1/2  requirement)  may  instead  make  a  one-time  election  of  10-year
    averaging  (at 1986 rates) and may elect to have the pre-1974 portion of the
    distribution taxed  at  1986 capital  gains  rates. The  special  5-year  or
    10-year  averaging treatment, as well as partial capital gains treatment, of
    lump sum distributions is applicable to a lump sum distribution from a  Plan
    only  if all other lump sum distributions (whether or not from the same Plan
    or Plans of a  similar type) received  during the same  taxable year by  the
    participant  are  treated  in the  same  manner.  Hence, for  example,  if a
    participant receives  a lump  sum  distribution from  the CODA,  the  Profit
    Sharing Retirement Plan

                                       26
<PAGE>
    and  the Employee Stock Ownership  Plan in the same  taxable year, he or she
    could not elect to use  5-year or 10-year averaging  on the CODA and  Profit
    Sharing Retirement Plan distributions while electing a rollover to an IRA of
    the distribution from the Employee Stock Ownership Plan.

        "Early"  distributions from the  Plans will result  in an additional 10%
    tax on the  taxable portion of  the distribution, except  to the extent  the
    distribution (i) is rolled over to an IRA or other qualified plan or (ii) is
    used  for deductible medical expenses.  "Early" distributions are in-service
    distributions (i.e., prior to termination  of employment) prior to the  date
    the participant attains age 59 1/2 unless due to the permanent disability of
    the  participant, and  distributions made  following termination  of service
    unless due to  the death of  the participant  or made to  a participant  who
    terminated  employment  during or  after the  calendar year  the participant
    attained the age of 55.

        (h)  A  participant  (or  his  or  her  spouse  in  the  event  of   the
    participant's  death) who (i) receives a  distribution from the Plans (other
    than certain mandatory distributions  after age 70 1/2)  and (ii) wishes  to
    defer  immediate tax upon receipt of  such distribution, may transfer (i.e.,
    "rollover") all  or  a portion  thereof,  exclusive  of the  amount  of  the
    participant's  voluntary  nondeductible contributions  (made to  those Plans
    which previously permitted the  participant to make voluntary  nondeductible
    contributions)  received in  the distribution, to  either an IRA  or, in the
    case of a participant, another  qualified retirement plan. To be  effective,
    the  "rollover"  must  be  completed  within  60  days  of  receipt  of  the
    distribution. Alternatively, the participant or spouse may request a  direct
    rollover  from the  Plans to  an IRA or,  in the  case of  a participant, to
    another qualified retirement plan.

        A participant  (or his  or her  spouse) who  does not  arrange a  direct
    rollover  to an IRA or  another qualified plan will  be subject to mandatory
    federal income tax withholding at a rate of 20% of the taxable distribution,
    even if the participant or spouse  later makes a rollover within the  60-day
    period.

        A  participant (or his or her spouse) who makes a valid "rollover" to an
    IRA will  defer  payment of  federal  income tax  until  such time  as  such
    participant  (or his or her spouse) actually begins to receive distributions
    from the IRA. IRA earnings accumulate on a tax-deferred basis until actually
    distributed; however, IRA funds may not be withdrawn without penalty until a
    participant (or his  or her  spouse) (i)  attains the  age of  59 1/2,  (ii)
    becomes disabled or (iii) dies. The Code requires that distributions from an
    IRA  or a  qualified retirement  plan begin  not later  than April  1 of the
    taxable year following the  year in which an  individual attains the age  of
    70   1/2,  at  which  time  periodic  distributions  may  continue  for  the
    participant's lifetime  or  for the  lifetime  of the  participant  and  the
    participant's spouse.

        (i)  The Code imposes a  15% excise tax on  "excess distributions" to an
    individual from  all qualified  retirement plans  and IRAs  (whether or  not
    plans  of  the same  employer). In  general, an  "excess distribution"  is a
    distribution or distributions  in excess  of $112,500 in  any calendar  year
    (adjusted  for cost-of-living increases).  For 1994, the  limit is $148,500.
    This limit is increased  to $562,500 (also  adjusted for cost-of-living)  in
    the case of a lump sum distribution as to which a qualified recipient elects
    5-year  or 10-year  averaging treatment.  For 1994,  the limit  is $742,500.
    Also, an individual was entitled to elect on his or her 1988 federal  income
    tax  return to  exclude benefits  accrued as  of August  1, 1986,  but these
    benefits are considered in  determining whether additional accrued  benefits
    are subject to the tax. For those individuals who did not elect this special
    rule, the $112,500/$562,500 limit is increased to $150,000/$750,000.

    In  addition to the federal income tax consequences applicable to all of the
Plans, the Deferred  Fund of the  CODA is intended  to be a  qualified "cash  or
deferred  arrangement" under  Section 401(k) of  the Code. A  participant in the
CODA who elects  to defer  a portion  of his or  her compensation  and have  the
Company  contribute it to the CODA will not  be subject to federal income tax on
the amounts contributed at the time  the contributions are made. However,  these
contributions  will  be subject  to social  security  taxes and  certain federal
unemployment   taxes.   Elective   deferrals    by   a   participant   to    his

                                       27
<PAGE>
or her CODA account is limited to $7,000 annually (adjusted for cost-of-living).
This  annual limit applies on an  employee-by-employee basis to all 401(k) plans
(including plans of  other employers)  in which the  employee participates.  For
calendar year 1994, the adjusted limit is $9,240.

    Generally,  the  Company  will  be  able  to  deduct  the  amounts  that  it
contributes to the  CODA pursuant to  employee elections to  defer a portion  of
their  compensation, as well as any matching or additional Company contributions
it makes to  the Deferred Fund.  The deduction will  be equal to  the amount  of
contributions made.

    With  respect to loans from the CODA commencing after December 31, 1986, any
interest paid  by the  participant will  not be  deductible, regardless  of  the
purpose  of the loan or use of the loan proceeds. Moreover, interest paid on any
loan from any of the Plans by a "key employee," as defined in Section 416(i)  of
the Code, will not be deductible.

    The  foregoing discussion is intended only  as a summary of certain relevant
federal income tax consequences and does not purport to be a complete discussion
of all  of the  tax consequences  of participation  in the  Plans.  Accordingly,
participants  should consult their own tax advisors with respect to all federal,
state and local tax effects of participation in the Plans. Moreover, the Company
does not  represent  that the  foregoing  tax  consequences will  apply  to  any
particular participant's specific circumstances or will continue to apply in the
future  and makes  no undertaking  to maintain  the tax-qualified  status of the
Plans.

BONUS COMPENSATION PLAN

  GENERAL

    The Company's Bonus Compensation Plan  became effective on February 1,  1984
and  was approved by the stockholders of  the Company at the 1984 Annual Meeting
of Stockholders. The Plan  provides for the distribution  of bonuses in cash  or
shares  of  Class  A Common  Stock  or  both. The  Bonus  Compensation  Plan was
originally adopted in 1974  by the Board  of Directors of  the Company and  then
provided  only for the payment of cash  bonuses. The Bonus Compensation Plan was
amended in 1976 to provide,  among other things, for  the payment of bonuses  in
securities  of the Company or  cash or a combination  of securities and cash and
was amended  and restated  in  its current  form on  April  2, 1991.  The  Bonus
Compensation  Plan is not subject  to ERISA and is  not intended to be qualified
under Section 401(a) of the Code.

  ELIGIBILITY AND PARTICIPATION

    All officers,  directors  and  employees  of the  Company  are  eligible  to
participate in and receive bonuses under the Bonus Compensation Plan.

  AWARDS

    Each year the Company establishes a bonus pool which is currently limited to
seven  percent of aggregate compensation paid or  accrued by the Company for all
persons eligible to receive  bonuses under the  Bonus Compensation Plan.  Awards
under  the Bonus  Compensation Plan are  generally made based  upon the employee
obtaining or achieving performance criteria and, in some cases, contingent  upon
a requirement that the employee purchase a specified number of shares of Class A
Common  Stock in the Limited  Market at the prevailing  Formula Price. Awards of
bonuses may be made in cash or shares  of Class A Common Stock or a  combination
of cash and shares and are made upon the recommendation of group managers or the
Chief  Executive  Officer of  the Company,  at the  discretion of  the committee
administering the Bonus Compensation Plan (the "Bonus Compensation  Committee").
Awards  of  bonuses  pursuant  to  the  Bonus  Compensation  Plan  are generally
distributed after  the  end of  the  fiscal year  to  which the  bonus  relates.
Pursuant to the Certificate of Incorporation, all shares of Class A Common Stock
awarded  under the Bonus Compensation Plan are subject to the Company's right of
first refusal  and  the  Company's  right  of  repurchase  upon  termination  of
employment  or affiliation. See "Description of Capital Stock -- Common Stock --
Restrictions on Class A Common Stock." Awards of shares of Class A Common  Stock
may also be subject to forfeiture, in

                                       28
<PAGE>
whole  or in part, in the event of the termination of the recipient's employment
or affiliation  with the  Company prior  to the  expiration of  certain  vesting
periods, as determined by the Bonus Compensation Committee.

    The  Bonus Compensation Plan also provides  for the award of special bonuses
("Spot Bonuses") to  reward extraordinary  effort or  special achievement.  Spot
Bonuses may be awarded and distributed to eligible persons at any time, in cash,
up  to  a maximum  of $1,000,  by a  group manager  or by  the President  of the
Company. Individual  awards, other  than  Spot Bonuses,  generally range  in  an
amount  from one week's salary to 25% of a recipient's annual salary, based upon
the recipient's position with the Company; however, the Bonus Compensation  Plan
does  not provide for  a maximum or minimum  number of shares  of Class A Common
Stock or an amount of cash which may be awarded to any recipient.

    Pursuant to the  Bonus Compensation Plan,  bonuses to members  of the  Bonus
Compensation  Committee (other than the Chief  Executive Officer of the Company)
must be  approved  by the  Chief  Executive Officer  and  bonuses to  the  Chief
Executive  Officer must be  approved by the  Board of Directors.  Members of the
Bonus Compensation Committee are ineligible to receive awards of Class A  Common
Stock  while serving on the Bonus  Compensation Committee. For services rendered
during the fiscal  year ended  January 31, 1993,  a total  of 7,776  individuals
received  an aggregate of approximately $11,760,000  in cash bonuses and 681,500
shares of Class A Common Stock.

  FEDERAL INCOME TAX CONSEQUENCES

    Awards under the Bonus Compensation Plan of cash bonuses and shares of Class
A Common Stock that are not subject to forfeiture are taxable as ordinary income
to the recipient in the year received. Awards of shares of Class A Common  Stock
that  are subject to  forfeiture will not  be recognized for  federal income tax
purposes by recipients at  the time such awards  are made, unless the  recipient
makes  an election, as discussed below, to  recognize the award as income at the
time received.

    The recipient  of  shares  of Class  A  Common  Stock that  are  subject  to
forfeiture  will recognize  income at  the time  all or  a portion  of the award
becomes nonforfeitable to the extent of the value of such nonforfeitable  shares
at  such  time. Such  recipient may,  however, elect  to recognize,  for federal
income tax purposes, the value of an award of shares of Class A Common Stock  on
the  date such  shares are  received, even though  the shares  remain subject to
forfeiture at that  time. The election  must be  made within 30  days after  the
award of shares.

    If  such an election is made, future appreciation in the value of the shares
of Class A Common Stock will not be treated as taxable compensation. However, if
the shares are forfeited after the taxable year in which such election is  made,
no  deduction will  be allowed to  the recipient.  The Company is  entitled to a
deduction at the time the recipient recognizes the award (or a portion  thereof)
as  taxable income in an amount equal  to the amount recognized by the recipient
as taxable income.

    The foregoing discussion is  intended only as a  summary of certain  federal
income  tax consequences and does not purport to be a complete discussion of all
of the  tax  consequences  of  participation in  the  Bonus  Compensation  Plan.
Accordingly,  recipients  of awards  under  the Bonus  Compensation  Plan should
consult their own tax advisors with respect to all federal, state and local  tax
effects  of participation in the Bonus  Compensation Plan. Moreover, the Company
does not  represent  that the  foregoing  tax  consequences will  apply  to  any
particular participant's specific circumstances.

  AMENDMENT AND TERMINATION

    The Bonus Compensation Plan may at any time be amended or terminated, either
by  the Company's  stockholders or  by the  Board of  Directors, except  that no
amendment  or  termination  of  the  Bonus  Compensation  Plan  may,  without  a
participant's   consent,  affect  any  bonus   award  previously  made  to  such
participant.

                                       29
<PAGE>
  ADMINISTRATION

    The Bonus  Compensation  Plan  is administered  by  the  Bonus  Compensation
Committee,  whose members consist of three or more directors. The members of the
Bonus Compensation Committee are appointed by and serve at the discretion of the
Company's Board  of  Directors.  Members of  the  Bonus  Compensation  Committee
receive  no compensation from the Bonus  Compensation Plan for services rendered
in connection therewith. The current members of the Bonus Compensation Committee
are J.R. Beyster (Chairman),  J.B. Wiesler and W.E.  Zisch. The address of  each
such  person  is Science  Applications  International Corporation,  10260 Campus
Point Drive, San Diego, CA 92121.

STOCK COMPENSATION PLANS

  GENERAL

    On April 9, 1994,  the Company adopted the  Stock Compensation Plan and  the
Management  Stock Compensation Plan.  In connection with  the Stock Compensation
Plans, the Company will  enter into a trust  agreement ("Trust Agreement")  with
State  Street Bank and Trust Company, as Trustee, establishing a trust ("Trust")
which will hold the accounts of participants under the Stock Compensation Plans.

  ELIGIBILITY, PARTICIPATION AND AWARDS

    All officers  and employees  of  the Company  (including directors  who  are
employees  of  the  Company) are  eligible  to  receive awards  under  the Stock
Compensation Plans.  However,  only a  select  group of  management  and  highly
compensated senior employees are eligible to receive awards under the Management
Stock  Compensation Plan. It is intended that the participants of the Management
Stock Compensation Plan be limited to individuals that would permit the plan  to
be  treated as a  "top hat" plan  under applicable Internal  Revenue Service and
Department of Labor regulations.

    Each year  the Company  will establish  a discretionary  stock  compensation
award  pool. Awards  under the Stock  Compensation Plans will  generally be made
upon the employee attaining or achieving performance criteria. Awards under  the
Stock  Compensation Plans will be determined by the Awarding Authority, which is
an individual or individuals to  be appointed by the  Board of Directors of  the
Company.  J.R. Beyster  is the current  Awarding Authority. The  address of J.R.
Beyster is Science  Applications International Corporation,  10260 Campus  Point
Drive, San Diego, CA 92121.

    Awards  will be made  in Share Units,  as defined in  the Stock Compensation
Plans. Each Share  Unit generally  corresponds to one  share of  Class A  Common
Stock  of the Company, but  the employee receiving an  award of Share Units will
not have a  direct ownership  interest in  the shares  of Class  A Common  Stock
represented  by the Share Units. The Company will contribute to the Trust either
shares of Class A  Common Stock, or  cash with which  the Trustee will  purchase
Class  A Common Stock, corresponding to the  Share Units awarded under the Plan.
Each employee receiving an award of Share Units will have an account established
on his or her  behalf in the Trust  credited with the shares  of Class A  Common
Stock allocated to the account based on the award of Share Units.

    Each  account established  in the Trust  under the  Stock Compensation Plans
will be subject to a vesting schedule not to exceed seven (7) years, established
by the Awarding  Authority. It is  contemplated that the  vesting schedule  will
generally provide for vesting at the rate of one-third at the end of each of the
fifth,  sixth  and  seventh years  following  the  date of  the  award. Unvested
portions of  the  account will  be  forfeited in  the  event of  termination  of
employment  for whatever reason (other than death)  prior to full vesting of the
account. Any  forfeited account  balances  may be  returned  to the  Company  or
reallocated to other participants as determined by the Company.

    Distribution  of vested account balances will occur  at the end of the seven
(7)-year vesting  period  (or  upon  termination  of  employment,  if  earlier).
However,  employees  may elect,  within 90  days of  the date  of the  award, to
receive distribution of the account as  it becomes vested or, alternatively,  in
the  case of the Management Stock Compensation Plan, to defer distribution until
termination of employment.

                                       30
<PAGE>
  PROVISIONS RELATING TO THE TRUST

    Although administered  under a  single Trust  Agreement, each  of the  Stock
Compensation  Plans is a  separate plan, and  the accounts of  each of the Stock
Compensation Plans are maintained under  a separate sub-trust with the  Trustee.
The assets of the sub-trust established for each of the Stock Compensation Plans
are not available to pay benefits or satisfy liabilities of the other Plan.

    The Trust is a so-called "grantor" trust or "rabbi" trust. The assets of the
Trust  are available to satisfy the creditors of the Company in the event of the
bankruptcy or insolvency of the Company. Accordingly, participants in the  Stock
Compensation Plans have no direct right to obtain shares of Class A Common Stock
or  other assets held in the Trust in the event of such insolvency or bankruptcy
and also have no direct rights  against the Company for their benefits.  Rather,
participants  have the limited rights of  a general creditor whose only recourse
is against the assets of  the Trust (along with  other general creditors of  the
Company).  The assets of the  Trust are not guaranteed  or insured by any party,
including the Company.

  FEDERAL INCOME TAX CONSEQUENCES

    Because awards under the Stock Compensation Plans are represented only by an
interest in the  Trust, and  because the  Trust is  intended to  be a  so-called
"grantor"  trust within the meaning of subpart  E, part I, subchapter J, chapter
1, subtitle A of the Code  (by virtue of the fact  that the assets of the  Trust
are  available  to satisfy  the creditors  of the  Company in  the event  of the
Company's bankruptcy or insolvency), the participants in the Stock  Compensation
Plans  should not be considered to have  taxable income until their accounts are
distributed or made available to them under the terms of the Stock  Compensation
Plans.  This tax treatment is consistent with a series of private letter rulings
issued by the Internal Revenue Service with respect to so-called "rabbi" trusts,
including a private letter ruling issued in  1992 with respect to a rabbi  trust
designed  to invest  primarily or  exclusively in  employer stock.  Although the
Company believes that  the analysis  contained in these  private letter  rulings
applies  to the Stock  Compensation Plans, the Stock  Compensation Plans are not
identical to the plans considered in the rulings, and, moreover, private  letter
rulings apply only to the taxpayer who requests and receives the ruling. Because
the  Company is not  applying for a  ruling on behalf  of the Stock Compensation
Plans, there can be no definite assurance that the above-described tax treatment
will apply. The foregoing  discussion is intended only  as a summary of  certain
relevant  federal income tax consequences and does  not purport to be a complete
discussion of  all  of  the  tax consequences  of  participation  in  the  Stock
Compensation  Plans.  Accordingly,  participants should  consult  their  own tax
advisors  with  respect  to  all  federal,  state  and  local  tax  effects   of
participation  in the Stock  Compensation Plans. Moreover,  the Company does not
represent that  the foregoing  tax  consequences will  apply to  any  particular
participant's specific circumstances or will continue to apply in the future.

  ERISA

    It  is intended that  the Management Stock Compensation  Plan be exempt from
the reporting and disclosure, participation  and vesting, funding and  fiduciary
responsibility  provisions  of  ERISA  as  a  plan  "which  is  unfunded  and is
maintained by  an  employer primarily  for  the purpose  of  providing  deferred
compensation  for a select group of  management or highly compensated employees"
(a so-called "top hat" plan). The  Department of Labor issued an opinion  letter
in  1992 indicating that a  rabbi trust established to  be invested primarily in
stock of the employer would  not cause the related  plan to be "funded."  Hence,
the related plan was entitled to rely on the top-hat exemption.

    It is intended that the Stock Compensation Plan be exempt from ERISA because
it  is not a plan which is designed to provide retirement income to employees or
which results in the  deferral of income by  employees for periods extending  to
the  termination of  employment or beyond.  Although the  Company believes these
ERISA exemptions are available to the Stock Compensation Plans, no Department of
Labor opinion is  being sought  and no  assurances can  be made  that the  ERISA
exemptions will definitely apply.

                                       31
<PAGE>
  AMENDMENTS AND TERMINATION

    The  Board of Directors may amend  or terminate the Stock Compensation Plans
for any reason,  including, but not  limited to, adverse  changes in  accounting
rules or tax laws or the bankruptcy, receivership or dissolution of the Company.
In  the event of amendment or termination, benefits will either be paid out when
due under the  terms of  the Stock  Compensation Plans or  paid out  as soon  as
practicable  as determined by the Stock Compensation Plans Committee in its sole
discretion.

  ADMINISTRATION

    The day-to-day administration of the Stock Compensation Plans is provided by
the Stock Compensation Plans  Committee appointed by the  Board of Directors  of
the  Company. D.W. Baldwin, S.P. Fisher, H.T.  Hicks and W. Reed are the current
members of the  Stock Compensation  Plans Committee.  The address  of each  such
person  is Science  Applications International  Corporation, 10260  Campus Point
Drive, San Diego,  CA 92121. Members  of the Committee  are eligible to  receive
awards under the Stock Compensation Plans.

1993 EMPLOYEE STOCK PURCHASE PLAN

  GENERAL

    The  1993  Employee  Stock Purchase  Plan  (the "Stock  Purchase  Plan") was
approved by  the stockholders  of the  Company  at the  1993 Annual  Meeting  of
Stockholders  and became effective on  July 9, 1993. The  Stock Purchase Plan is
intended to qualify under  Section 423(b) of the  Code. The Stock Purchase  Plan
provides  for the  purchase of Class  A Common Stock  by participating employees
through voluntary payroll deductions. At each Trade Date, the Trustee  purchases
for  the account  of each  participant that  whole number  of shares  of Class A
Common Stock which may be acquired from the funds available in the participant's
stock purchase account,  together with the  Company's five percent  contribution
described below. The Stock Purchase Plan is not subject to ERISA.

  ELIGIBILITY

    Generally, all of the Company's employees are eligible to participate in the
Stock  Purchase Plan except for  employees in non-participating subsidiaries. No
employee, however, who owns capital stock  of the Company having more than  five
percent  of the  voting power  or value of  such capital  stock will  be able to
participate. An employee's eligibility to participate in the Stock Purchase Plan
will terminate immediately upon termination of employment with the Company.

    Employees may participate in the Stock Purchase Plan by completing a payroll
deduction authorization form and providing it to the designated officials of the
Company. The minimum payroll deduction allowed is three percent of  compensation
and the maximum allowable deduction is 10% of compensation. Further, no employee
is  entitled to purchase an amount of Class  A Common Stock having a fair market
value (measured as of its  purchase date) in excess  of $25,000 in any  calendar
year  pursuant to the Stock Purchase Plan  and any other employee stock purchase
plan that may be adopted by the Company.

  PURCHASE OF SHARES

    Shares of Class A Common Stock  purchased under the Stock Purchase Plan  may
be  acquired in  the Limited  Market or  purchased from  the Company  out of its
authorized but unissued shares. See "Market Information -- The Limited  Market."
A  maximum of 650,000 shares  of Class A Common  Stock (subject to adjustment in
the event of  a change  in the capitalization  of the  Company effected  without
receipt  of consideration by  the Company) have been  authorized for issuance by
the Company as newly issued shares under the Stock Purchase Plan. For the fiscal
year ended  January  31, 1994,  248,077  shares of  Class  A Common  Stock  were
purchased for the accounts of 1,341 participants in the Company's Stock Purchase
Plan.

    The  purchase  price to  be  paid for  the shares  of  Class A  Common Stock
acquired for the accounts of participants will be the prevailing Formula  Price.
Of this amount, 95% will be paid out of the funds contributed by the participant
and five percent will be paid by the Company.

                                       32
<PAGE>
  DISTRIBUTION AND WITHDRAWALS

    Shares  of Class A Common Stock acquired  under the Stock Purchase Plan will
be distributed to each participant  no later than 90 days  after the end of  the
Plan  Year in which the acquisition occurred and  in the interim will be held by
the Trustee for the account of such participant.

    Pursuant to the Certificate of Incorporation,  all shares of Class A  Common
Stock  purchased pursuant  to the  Stock Purchase  Plan will  be subject  to the
Company's right of repurchase upon  the participant's termination of  employment
or affiliation with the Company at the then prevailing Formula Price in the case
of  shares held by the participant directly,  and at the Formula Price in effect
at the time of the annual distribution of shares out of the Stock Purchase  Plan
in  the case of shares  held by the Trustee for  the benefit of the participant.
All such shares will also be subject to the Company's right of first refusal  in
the  event that the  participant desires to  sell such shares  other than in the
Limited  Market.  See  "Description  of   Capital  Stock  --  Common  Stock   --
Restrictions on Class A Common Stock."

    Participants may withdraw the money held in their stock purchase accounts at
any  time prior to the acquisition of  shares of Class A Common Stock therewith,
although upon doing so  the participant will not  be eligible to participate  in
the  Stock Purchase Plan until the following Plan Year after such withdrawal. No
interest will be paid on  the money held in the  stock purchase accounts of  the
participants.

  AMENDMENT AND TERMINATION

    The  Board  of Directors  of  the Company  may  suspend or  amend  the Stock
Purchase Plan in  any respect,  except that no  amendment may  (i) increase  the
maximum  number of shares authorized to be issued by the Company under the Plan,
(ii) increase the  Company's contribution  for each share  purchased above  five
percent  of the applicable purchase price for  such share, (iii) cause the Stock
Purchase Plan to fail to qualify under  Section 423(b) of the Code or (iv)  deny
to  participating employees  the right  at any time  to withdraw  from the Stock
Purchase Plan and thereupon obtain all amounts then due to their credit in their
Stock Purchase Accounts.  The Stock  Purchase Plan  will terminate  on July  31,
1995.

  ADMINISTRATION

    The Stock Purchase Plan is administered by the Company's Stock Purchase Plan
Committee  (the "Stock Purchase Committee"), whose  members are appointed by and
serve at the  discretion of  the Company's Board  of Directors.  Members of  the
Stock  Purchase Committee receive  no compensation from  the Stock Purchase Plan
for services rendered in connection therewith. The current members of the  Stock
Purchase  Committee are A. Maharry,  W. Reed and W.A.  Roper, Jr. The address of
each such person is Science Applications International Corporation, 10260 Campus
Point Drive, San Diego, CA 92121.

  TRUSTEE

    The Trustee of the Stock Purchase Plan is the Company.

  FEDERAL INCOME TAX CONSEQUENCES

    For federal income tax purposes, no  taxable income will be recognized by  a
participant  in the Stock Purchase Plan until  the taxable year of sale or other
disposition of the shares of Class A Common Stock acquired under the Plan.  When
the shares are disposed of by a participant two years or more from the date such
shares  were  purchased  for  the  participant's  account  by  the  Trustee, the
participant must recognize ordinary income  for the taxable year of  disposition
to  the extent of the lesser  of (i) the excess of  the fair market value of the
shares on the purchase date  over the amount of the  purchase price paid by  the
participant  (the "Discount") or (ii) the amount  by which the fair market value
of the shares at disposition or death exceeds the purchase price, with any  gain
in  excess of such ordinary  income amount being treated  as a long-term capital
gain, assuming  that  the  shares are  a  capital  asset in  the  hands  of  the
participant.  In the event of a participant's death while owning shares acquired
under the Stock Purchase Plan, ordinary income must be recognized in the year of

                                       33
<PAGE>
death in the  amount specified in  the foregoing sentence.  When the shares  are
disposed  of  prior  to  the  expiration  of  the  two-year  holding  period  (a
"disqualifying disposition"), the participant must recognize ordinary income  in
the amount of the Discount, even if the disposition is by gift or is at a loss.

    In  the cases  discussed above  (other than  death), the  amount of ordinary
income recognized by a participant  is added to the  purchase price paid by  the
participant  and this amount becomes the tax basis for determining the amount of
the capital gain or loss from the disposition of the shares.

    Net capital gains are presently taxed  at a maximum federal income tax  rate
of  28%,  compared to  a maximum  rate  of 39.6%  for ordinary  income. However,
limitations on itemized deductions and  the phaseout of personal exemptions  may
result in effective marginal tax rates higher than 28% for net capital gains and
39.6% for ordinary income.

    The  Company will not be entitled to a  deduction at any time for the shares
issued pursuant to the Stock Purchase Plan if a participant holding such  shares
continues  to hold his or her shares or  disposes of his or her shares after the
required two-year holding period or dies while holding such shares. If, however,
a participant disposes of  such shares prior to  the expiration of the  two-year
holding  period, the Company is allowed a  deduction to the extent of the amount
of ordinary  income includable  in  gross income  by  such participant  for  the
taxable year as a result of the premature disposition of the shares.

    The  foregoing discussion is intended only  as a summary of certain relevant
federal income tax consequences and does not purport to be a complete discussion
of all of  the tax  consequences of participation  in the  Stock Purchase  Plan.
Accordingly,  participants should consult their own tax advisors with respect to
all federal, state and local tax effects of participation in the Stock  Purchase
Plan.   Moreover,  the  Company  does  not  represent  that  the  foregoing  tax
consequences will  apply to  any participant's  specific circumstances  or  will
continue  to  apply in  the  future and  makes  no undertaking  to  maintain the
tax-qualified status of the Stock Purchase Plan.

STOCK OPTION PLANS

1982 STOCK OPTION PLAN

  GENERAL

    The 1982 Stock Option Plan was approved by the Company's Board of  Directors
in  March 1982 and by the stockholders of the Company at the 1982 Annual Meeting
of Stockholders, and was amended by the Board of Directors in April 1987,  which
amendments  were approved by the  stockholders in June 1987  (as so amended, the
"1982 Option  Plan"). The  1982  Option Plan  authorized  the granting  of  both
incentive  stock options ("ISO's") and  non-qualified stock options with respect
to an aggregate of 22,500,000 shares  of capital stock. Commencing in  September
1987,  it  has been  the practice  of  the Company  to grant  only non-qualified
options due primarily to the favorable tax benefits received by the Company upon
the exercise of  such options. See  "General Provisions of  the Option Plans  --
Federal  Income  Tax  Consequences."  As  of March  14,  1994,  the  Company had
7,313,629 shares of Class A Common Stock reserved for issuance upon exercise  of
non-qualified  options previously granted  under the 1982  Option Plan; no ISO's
are outstanding.  The 1982  Option Plan  terminated  on, and  no option  may  be
granted  after, June 10, 1992. The 1982 Option  Plan is not subject to ERISA and
is not intended to be qualified under Section 401(a) of the Code.

    The exercise  price  of  options  granted under  the  1982  Option  Plan  is
determined  by the Stock Option  Committee and may not be  less than 100% of the
fair market value of the capital stock  on the date of grant. Upon the  exercise
of  an option, the exercise price is fully payable, in whole or in part, in cash
or in  shares of  capital stock  valued  at the  Formula Price  on the  date  of
exercise.   Any  withholding  required  as  a   result  of  the  exercise  of  a
non-qualified option may, at  the discretion of the  Stock Option Committee,  be
satisfied by withholding in shares of capital stock of the Company valued at the
Formula  Price on the date of exercise. All options granted pursuant to the 1982
Option Plan  are  non-transferable except  by  will  or the  laws  of  intestate
succession.

                                       34
<PAGE>
    Options  granted under the 1982  Option Plan may be  exercised over a period
specified in the stock option agreement (which period may not exceed 10  years),
except  for options granted to persons owning shares possessing more than 10% of
the total combined voting power of all  classes of capital stock of the  Company
or  any of  its subsidiaries, which  may not  be exercisable for  more than five
years from the date of grant. If an optionee's employment terminates as a result
of retirement or  permanent disability,  all options  may be  exercised, to  the
extent  exercisable at the date of termination, for three additional months, but
in no event beyond their respective expiration dates. If an optionee dies  while
employed  by the Company, all options, to  the extent exercisable at the date of
death, may, for  up to one  additional year (but  in no event  later than  their
respective  expiration dates), be  exercised by the optionee's  estate or by the
person to whom the  optionee's rights pass. Upon  termination of employment  for
any  other reason, all options will terminate as of the date of such termination
of employment, unless otherwise  provided by the Stock  Option Committee at  the
date  of grant  (but in no  event shall the  option be exercisable  for a period
extending beyond 90 days following such termination). Currently, the practice of
the Stock Option  Committee is to  provide in  the grant that  the optionee  may
exercise the option within 30 days following termination of employment, but only
to  the  extent  that  the  option  was  exercisable  as  of  the  date  of such
termination.

  ELIGIBILITY AND PARTICIPATION

    The 1982 Option  Plan terminated on,  and no options  may be granted  after,
June  10,  1992.  As  of  March 14,  1994,  there  were  11,178  separate option
agreements with optionees outstanding under the 1982 Option Plan.

1992 STOCK OPTION PLAN

  GENERAL

    The 1992 Stock  Option Plan  (the "1992 Option  Plan") was  approved by  the
Board  of Directors on April 10, 1992 and  by the stockholders of the Company at
the 1992 Annual Meeting of Stockholders.  The 1992 Option Plan provides for  the
granting  of non-qualified options to purchase a maximum of 12,000,000 shares of
Class A  Common  Stock  to  key employees,  consultants,  directors  and  others
expected  to contribute to the success of the Company. As of March 14, 1994, the
Company had 11,996,371 shares of Class A Common Stock reserved for issuance upon
the exercise of options granted or to be granted under the 1992 Option Plan. The
1992 Option Plan is  not subject to  ERISA and is not  intended to be  qualified
under Section 401(a) of the Code.

    The  exercise price of options granted under the 1992 Option Plan is 100% of
the fair market value of the Class A Common Stock on the date of grant. Upon the
exercise of an option,  the exercise price must  be paid in full  in cash or  in
shares  of Class  A Common  Stock valued  at the  Formula Price  on the  date of
exercise. Any withholding required as a result of the exercise of an option may,
at the discretion of the Stock Option Committee, be satisfied by withholding  in
shares  of Class  A Common  Stock valued  at the  Formula Price  on the  date of
exercise. All options granted  under the 1992  Option Plan are  non-transferable
except by will or the laws of intestate succession.

    Options  granted under the 1992  Option Plan may be  exercised over a period
specified in the Option Agreement (which period may not exceed 10 years). If  an
optionee's  employment terminates as  a result of  retirement or permanent total
disability, all options may be exercised, to the extent exercisable at the  date
of  termination, for 90 additional days, but in no event beyond their respective
expiration dates. If an optionee dies  while employed by or affiliated with  the
Company,  all  unexercised options,  to the  extent exercisable  at the  date of
death, may, for  up to one  additional year, or  such shorter period  as may  be
specified  in the Option  Agreement (but not  beyond their respective expiration
dates), be  exercised  by  the optionee's  estate  or  the person  to  whom  the
optionee's  rights pass by  will or the  laws of descent  and distribution. Upon
termination of employment for any other reason, all options will terminate as of
the date  of termination  of  employment or  affiliation,  unless such  date  is

                                       35
<PAGE>
extended  by  the  Stock  Option  Committee  (but  not  beyond  their respective
expiration dates). Currently, the practice of  the Stock Option Committee is  to
provide  in the grant that  the optionee may exercise  the option within 30 days
following termination of employment or affiliation, but only to the extent  that
the option was exercisable as of the date of such termination.

  ELIGIBILITY AND PARTICIPATION

    The  persons eligible to receive options under  the 1992 Option Plan are key
employees, directors and consultants. No option may be granted to any individual
who, at the time the option is granted, owns more than 10% of the total combined
voting power of all  classes of capital  stock of the Company.  As of March  14,
1994,  there were  7,187 separate  option agreements  with optionees outstanding
under the 1992 Option Plan. Other than the foregoing, the 1992 Option Plan  does
not  provide any limit as to the number of shares that may be subject to options
granted to any one individual.

  AMENDMENT AND TERMINATION

    The 1992 Option Plan may be amended, suspended or terminated by the Board of
Directors, except  that no  such  amendment may,  without  the approval  of  the
holders  of outstanding shares of  the Company having a  majority of the general
voting power, (i) increase the maximum number of shares for which options may be
granted  (other  than  by  reason  of  changes  in  capitalization  and  similar
adjustments), (ii) change the provisions of the 1992 Option Plan relating to the
establishment  of the exercise price (other  than the provisions relating to the
manner of determination of fair market  value of the Company's capital stock  to
conform  to  any  applicable  requirements of  the  Code  or  regulations issued
thereunder) or (iii)  permit the  granting of options  to members  of the  Stock
Option  Committee. The 1992 Option  Plan by its terms  will terminate on, and no
option may be granted after, July 31, 1995.

GENERAL PROVISIONS OF THE OPTION PLANS

  GENERAL

    All shares issued  upon exercise of  options granted under  the 1982  Option
Plan  or the 1992 Option Plan (collectively,  the "Option Plans") are subject to
(i) the Company's right of first refusal in the event that the optionee  desires
to  sell  his or  her  shares other  than  in the  Limited  Market and  (ii) the
Company's right of repurchase upon  termination of the optionee's employment  or
affiliation.  See "Description of Capital Stock  -- Common Stock -- Restrictions
on Class A Common  Stock." Only shares  of Class A Common  Stock will be  issued
upon  exercise of options. See "Description of  Capital Stock -- Common Stock --
General."

    The Company follows  the practice  of granting stock  options to  employees,
contingent  upon the employee  attaining a certain level  of contract awards for
the Company during a specified  period or satisfying other performance  criteria
and,  in some  cases, also contingent  upon a requirement  that such individuals
purchase a specified number  of shares of  Class A Common  Stock in the  Limited
Market  at the prevailing Formula Price. Options generally become exercisable on
a cumulative basis over a four-year period.

    If the outstanding shares  of the capital stock  of the Company are  changed
into, or exchanged for a different number or kind of shares or securities of the
Company  through reorganization,  merger, recapitalization,  reclassification or
similar transaction, or if the number of outstanding shares is changed through a
stock split,  stock dividend,  stock consolidation  or similar  transaction,  an
appropriate  adjustment  (determined  by  the Board  of  Directors  in  its sole
discretion) will be made in the number and kind of shares and the exercise price
per share of options which are  outstanding or which may be granted  thereafter.
No adjustment to the number of shares reserved for issuance by the Company under
the  1982 Option Plan was made as a  result of the reorganization of the Company
in 1984. As of  March 14, 1994,  there were 7,313,629 shares  of Class A  Common
Stock  reserved for issuance under the 1982 Option Plan and 11,996,371 shares of
Class A Common Stock reserved for issuance under the 1992 Option Plan.

                                       36
<PAGE>
    Under the 1982 Option  Plan, the Stock Option  Committee may accelerate  the
exercisability  of  options  in the  case  of  an optionee  whose  employment is
terminated by reason of a sale or other disposition by the Company of assets  in
respect  of  which the  optionee  was employed;  and  options will  become fully
exercisable in the  case of  (i) approval  of the Board  of Directors  of (a)  a
consolidation or merger in which the Company is not the surviving corporation or
pursuant  to  which  shares  of  capital stock  would  be  converted  into cash,
securities or other property, other than  a merger in which stockholders of  the
Company  immediately prior thereto will have the same proportionate ownership of
capital stock  of the  surviving corporation  immediately thereafter,  or (b)  a
sale,  lease, exchange  or other  transfer of  all or  substantially all  of the
assets of  the  Company or  (ii)  any person  (other  than the  Company  or  any
subsidiary  or employee benefit  plan thereof) becoming  the beneficial owner of
more than 25% of the outstanding Common Stock without the prior approval of  the
Board of Directors.

    Under  the 1992 Option Plan, the  options will become fully exercisable upon
any person (other than  the Company or any  subsidiary or employee benefit  plan
thereof)  becoming  the beneficial  owner of  more than  25% of  the outstanding
capital stock without the  prior approval of the  Board of Directors. The  Stock
Option  Committee  is  also given  the  discretion  to accelerate  or  defer the
exercise of options in other circumstances, at the Committee's discretion.

  ADMINISTRATION

    The Option  Plans  are administered  by  the Stock  Option  Committee  whose
members consist of three or more directors or other individuals appointed by and
serve  at the discretion of the Company's Board of Directors. The members of the
Stock Option Committee are not eligible to receive options while serving on  the
Stock  Option Committee. The Stock Option Committee is appointed annually by the
Board of Directors,  which may  also fill vacancies  or replace  members of  the
Stock  Option Committee. Subject to the  express provisions of the Option Plans,
the Stock Option Committee has the authority to (i) interpret the Option  Plans,
(ii)  prescribe, amend and rescind rules  and regulations relating to the Option
Plans, (iii) determine the individuals  to whom and the  time or times at  which
options  may be granted  and the number of  shares to be  subject to each option
granted under the Option Plans, (iv)  determine the terms and conditions of  the
option  agreements under the Option Plans (which  need not be identical) and (v)
make all other determinations necessary  or advisable for the administration  of
the  Option Plans. In addition, the Stock Option Committee may, with the consent
of the affected optionees and subject  to the general limitations of the  Option
Plans,  make any adjustment in the exercise  price, the number of shares subject
to, or the term of, any outstanding option by cancellation of such option and  a
subsequent  regranting of such  option, or by amendment  or substitution of such
option. Options which have  been so amended, regranted  or substituted may  have
higher  or lower exercise prices, cover a  greater or lesser number of shares of
capital stock, or  have longer  or shorter terms,  than the  prior options.  The
members  of the Stock  Option Committee receive no  compensation from the Option
Plans for services rendered in connection therewith. The current members of  the
Stock Option Committee are J.R. Beyster (Chairman), J.B. Wiesler and W.E. Zisch.
The   address  of  each  such   person  is  Science  Applications  International
Corporation, 10260 Campus Point Drive, San Diego, CA 92121.

  FEDERAL INCOME TAX CONSEQUENCES

    NON-QUALIFIED OPTIONS.  All outstanding  options under the 1982 Option  Plan
and  all  options  granted or  to  be granted  under  the 1992  Option  Plan are
non-qualified options. Generally, the optionee will  not be taxed upon grant  of
any non-qualified option but rather, at the time of exercise of such option, the
optionee  will recognize ordinary  income for federal income  tax purposes in an
amount equal to the excess of the fair  market value at the time of exercise  of
the  capital stock purchased over the exercise price. The Company will generally
be entitled to  a tax deduction  at such time  and in the  same amount that  the
optionee realizes ordinary income.

    If  capital stock  acquired upon the  exercise of a  non-qualified option is
later sold or exchanged, then the difference between the sale price and the fair
market value of such capital stock  on the date which governs the  determination
of   ordinary   income  is   generally  taxable   (provided   the  stock   is  a

                                       37
<PAGE>
capital asset in the holder's hands) as long-term or short-term capital gain  or
loss  depending upon whether  the holding period  for such capital  stock at the
time of disposition is more or less than one year.

  EXERCISE WITH SHARES OF CAPITAL STOCK

    If payment  of the  exercise price  of  a non-qualified  option is  made  by
surrendering  previously  owned shares  of  capital stock,  the  following rules
apply:

        (a) No gain or loss will be  recognized as a result of the surrender  of
    shares   in  exchange  for  an  equal   number  of  shares  subject  to  the
    non-qualified option, and the surrender of  shares will not be treated as  a
    disqualifying disposition of any stock acquired through exercise of an ISO.

        (b)  The number of shares received  equal to the shares surrendered will
    have a  basis equal  to the  shares surrendered  and a  holding period  that
    includes the holding period of the shares surrendered.

        (c)  Any additional shares received (i) will be taxed as ordinary income
    in an amount equal  to the fair market  value of the shares  at the time  of
    exercise,  (ii) will have  a basis equal  to the amount  included in taxable
    income by the optionee and (iii) will  have a holding period that begins  on
    the date of the exercise.

    The  foregoing discussion is  intended only as a  summary of certain federal
income tax consequences and does not purport to be a complete discussion of  all
of  the  tax consequences  of participation  in  the Option  Plans. Accordingly,
holders of options granted under the  Option Plans should consult their own  tax
advisors  for specific advice  with respect to  all federal, state  or local tax
effects before exercising  any options  and before  disposing of  any shares  of
capital  stock acquired  upon the exercise  of an option.  Moreover, the Company
does not represent that the foregoing  tax consequences apply to any  particular
option holder's specific circumstances or will continue to apply in the future.

<PAGE>
                          DESCRIPTION OF CAPITAL STOCK

GENERAL

    The Company is  authorized to  issue 100,000,000  shares of  Class A  Common
Stock,  par value $.01 per share, 5,000,000  shares of Class B Common Stock, par
value $.05 per share,  and 3,000,000 shares of  Preferred Stock, par value  $.05
per  share (the "Preferred Stock"). As of  March 14, 1994, there were 44,125,061
shares of Class A Common  Stock, 360,880 shares of Class  B Common Stock and  no
shares  of Preferred Stock issued and outstanding.  The Class A Common Stock and
Class B Common Stock are sometimes  collectively or individually referred to  as
the "Common Stock."

COMMON STOCK

  GENERAL

    Except as otherwise provided by law, the holders of shares of Class A Common
Stock  and Class B Common Stock vote together  as a single class in all matters,
with each holder  of Class A  Common Stock having  one vote per  share and  each
holder  of Class  B Common  Stock having  five votes  per share.  The holders of
shares of Class A Common Stock and Class B Common Stock are entitled to cumulate
their votes  for the  election  of directors.  Cumulative voting  entitles  each
stockholder  to cast  the number of  votes that  equals the number  of shares of
Class A Common Stock or five times the number of shares of Class B Common  Stock
held  by such stockholder multiplied  by the number of  directors to be elected.
Each stockholder  may  cast all  of  such votes  for  a single  nominee  or  may
distribute them among any two or more nominees as such stockholder sees fit. The
Certificate  of  Incorporation  provides  for a  classified  Board  of Directors
consisting of  three classes  of directors,  as  nearly as  equal in  number  as
practicable.  The  number  of  authorized directors  is  currently  fixed  at 22
directors of which 8 are Class I and the remaining positions are evenly  divided
between  Class II and  Class III directors.  Each year the  stockholders elect a
different class of  directors to serve  a three-year  term. As a  result of  the
classification  of the  Board of  Directors, the  votes of  a greater  number of
shares would be  required to ensure  the election  of a director  than would  be
required without such classification.

    Subject  to the  prior rights  of the  holders of  any Preferred  Stock then
outstanding, the holders of Class  A Common Stock and  Class B Common Stock  are
entitled to receive dividends, out of funds legally available therefor, when and
as  declared by the Board of Directors and to participate equally and ratably in
the net  assets  of the  Company  available for  distribution  in the  event  of
liquidation,  dissolution or  winding up,  after payment  of any  amounts due to
creditors; provided, however, that any dividend or distribution with respect  to
a share of Class B Common Stock must be five times the dividend or distribution,
as the case may be, with respect to a share of Class A Common Stock.

    Holders  of Class A  Common Stock have  no conversion rights  and holders of
Class A Common Stock and Class B Common Stock have no preemptive or subscription
rights.  Neither  class  of  Common  Stock  may  be  subdivided,   consolidated,
reclassified  or  otherwise  changed unless  the  relative  powers, preferences,
rights, qualifications,  limitations and  restrictions applicable  to the  other
class  of Common Stock are maintained.  In any merger, consolidation or business
combination to which the Company is a party (other than a merger,  consolidation
or  business combination in  which the Company is  the surviving corporation and
which does not result  in any reclassification of  or change in the  outstanding
shares  of Common Stock), the consideration to  be received with respect to each
share of Class B Common Stock must  be equal to five times the consideration  to
be  received with respect to each share of  Class A Common Stock, except that if
capital stock is distributed in any such transaction, such shares may differ  as
to  the rights of the holders thereof only to the extent that such rights differ
pursuant to Article FOURTH  of the Certificate of  Incorporation. All shares  of
Class A Common Stock and Class B Common Stock presently outstanding are, and the
shares  offered  hereby  upon full  payment  therefor  will be,  fully  paid and
nonassessable.

    Pursuant to the terms  of the Certificate of  Incorporation, the Company  is
prohibited  from issuing  any additional  shares of  Class B  Common Stock. Each
share of Class B Common Stock is convertible at

                                       39
<PAGE>
any time, at  the option  of the  holder thereof, into  five shares  of Class  A
Common  Stock, and all shares of Class  B Common Stock reacquired by the Company
will be retired and will not be available for reissuance.

    Article FOURTEENTH of  the Certificate of  Incorporation generally  requires
that  mergers and certain other  business combinations ("Business Combinations")
between the Company  and any holder  of five  percent or more  of the  Company's
outstanding voting power (a "Related Person") must be approved by the holders of
securities  having 80% of the Company's outstanding  voting power, as well as by
the holders of a majority of such  securities that are not owned by the  Related
Person.  Under Delaware  law, unless  the Certificate  of Incorporation provides
otherwise, only a majority of the Company's outstanding voting power is required
to approve certain of  these transactions, such  as mergers and  consolidations,
while  certain  other  of  these  transactions  would  not  require  stockholder
approval.

    The 80% and  majority of  independent voting power  requirements of  Article
FOURTEENTH (the "Supermajority Vote Requirements") will not apply, however, to a
Business  Combination with a Related Person,  if (i) the transaction is approved
by the Board of Directors prior to the time the Related Person becomes a Related
Person (i.e., prior to the time the Related Person acquired beneficial ownership
of five percent  or more of  the Company's outstanding  voting power), (ii)  the
transaction  is approved by at  least a majority of the  members of the Board of
Directors who are unaffiliated  with the Related Person  and who were  directors
before  the  Related  Person  became  a Related  Person  or  (iii)  the Business
Combination involves only the  Company and one or  more of its subsidiaries  and
certain other conditions are satisfied.

    Article  FOURTEENTH also provides  that in the  event a Business Combination
with a  Related  Person  subject  to  the  Supermajority  Vote  Requirements  is
consummated,  stockholders  of  the  Company  who  voted  against  the  Business
Combination, at their option, will  have the right to  receive a price which  is
equal to (i) the price offered by the Related Person in the Business Combination
or  (ii) the  greater of  (a) the highest  price per  share paid  by the Related
Person in acquiring shares of capital stock of the Company or (b) a price  which
bears  the same  percentage relationship  to the  market price  of the Company's
capital stock immediately preceding the announcement of the Business Combination
as the highest price paid by the Related Person for any of the Company's capital
stock bears  to the  market price  of the  Company's capital  stock  immediately
before the Related Person initially acquired any shares of the Company's capital
stock.

    Article  FOURTEENTH was  adopted by the  stockholders of the  Company at the
1983 Annual Meeting of Stockholders and  the full text of such Article  appeared
as  Exhibit  B to  the Company's  Proxy Statement  for that  meeting. Additional
copies of  Article FOURTEENTH  may be  obtained, upon  request, by  writing  the
Company  at 10260  Campus Point Drive,  San Diego,  California 92121, Attention:
Corporate Secretary.

    The Company acts as its own transfer agent for the Class A Common Stock  and
Class B Common Stock.

    As  of March 14,  1994, there were  10,038 record holders  of Class A Common
Stock and 135 record holders of Class B Common Stock.

  RESTRICTIONS ON CLASS A COMMON STOCK

    All the shares of  Class A Common Stock  presently outstanding are, and  all
shares  of  Class A  Common Stock  offered  hereby will  be, subject  to certain
restrictions (including  restrictions on  their  transferability) set  forth  in
Article  FOURTH of the Certificate  of Incorporation, which restrictions provide
substantially as follows:

    RIGHT OF REPURCHASE UPON TERMINATION OF EMPLOYMENT OR AFFILIATION

    All shares of Class A Common Stock owned  by a person who is an employee  or
director  of, or  a consultant  to, the  Company (except  for shares  of Class A
Common Stock that are held by a stockholder

                                       40
<PAGE>
who received  such shares  (i)  in connection  with  the reorganization  of  the
Company  in 1984 in exchange  for shares of the  Company which immediately prior
thereto were not subject to a right of repurchase upon termination of employment
or affiliation on the part of the Company, (ii) upon exercise of a non-qualified
stock option granted  prior to October  1, 1981 under  the Company's 1979  Stock
Option Plan which were not converted into ISO's, (iii) in exchange for shares of
Class  B  Common Stock  that  were not  subject to  a  right of  repurchase upon
termination of employment  or affiliation  on the part  of the  Company or  (iv)
pursuant to a stock dividend or a stock split on the outstanding shares of Class
A Common Stock which have been theretofore issued under any of the circumstances
described  in clauses (i), (ii),  (iii) or this clause  (iv)) will be subject to
the Company's  right  of  repurchase  upon  the  termination  of  such  holder's
employment  or affiliation with the Company.  Such right of repurchase will also
be applicable to all shares  of Class A Common Stock  which such person has  the
right  to  acquire after  his or  her termination  of employment  or affiliation
pursuant to  any  of  the  Company's employee  benefit  plans  (other  than  the
Company's  Profit Sharing  Retirement Plan,  Profit Sharing  Retirement Plan II,
Employee Stock Ownership Plan or CODA,  or any other retirement or pension  plan
adopted  by the Company or  any of its subsidiaries which  by its terms does not
provide for  the Company's  right to  repurchase shares  issued thereunder  upon
termination  of employment  or affiliation) or  pursuant to any  option or other
contractual  right  to  acquire  shares  of  Class  A  Common  Stock  which  was
outstanding at the date of such termination of employment or affiliation.

    The  Company's right of repurchase is  exercised by mailing a written notice
to  such  holder  within  60   days  following  termination  of  employment   or
affiliation.  If  the Company  repurchases  the shares,  the  price will  be the
Formula Price per share  (i) on the  date of such  termination of employment  or
affiliation,  in the case of shares owned by  the holder at that date and shares
issuable to  the  holder  after  that  date pursuant  to  any  option  or  other
contractual  right  to  acquire  shares  of  Class  A  Common  Stock  which were
outstanding at that date or (ii) on the date such shares are distributed to  the
holder,  in the  case of  shares distributable  to the  holder after  his or her
termination of  employment  or affiliation  pursuant  to any  of  the  Company's
employee benefit plans. The Company will, in the event it exercises its right of
repurchase upon termination of employment or affiliation, pay for such shares in
cash within 90 days after the date referred to in (i) or (ii) above, as the case
may be.

    RIGHT OF FIRST REFUSAL

    In  the event that a holder  of Class A Common Stock  desires to sell any of
his or her shares to a third party other than in the Limited Market, such person
must first give notice to the Corporate Secretary of the Company consisting  of:
(i)  a signed statement  setting forth such  holder's desire to  sell his or her
shares of Class A Common Stock and that he or she has received a bona fide offer
to purchase  such shares;  (ii) a  statement signed  by the  intended  purchaser
containing  (a)  the  intended  purchaser's  full  name,  address  and  taxpayer
identification number, (b) the number of  shares to be purchased, (c) the  price
per  share to be paid, (d) the other  terms under which the purchase is intended
to be made and (e) a representation  that the offer, under the terms  specified,
is  bona fide and (iii) if the purchase price is payable in cash, in whole or in
part, a copy of  a certified check,  cashier's check or  money order payable  to
such holder from the purchaser in the amount of the purchase price to be paid in
cash.

    Upon  receiving such  notice, the Company  will have  the right, exercisable
within 14 days, to  purchase all of  the shares specified in  the notice at  the
offer price and upon the same terms as set forth in the notice. In the event the
Company  does not exercise such right, the  holder may sell the shares specified
in the notice within 30 days thereafter to the person specified in the notice at
the price and upon the  terms and conditions set  forth therein. The holder  may
not  sell such shares  to any other person  or at any different  price or on any
different terms without first re-offering the shares to the Company.

    TRANSFERS OTHER THAN BY SALE

    Except for sales in the Limited Market and as described above, no holder  of
Class  A Common Stock may sell, assign, pledge, transfer or otherwise dispose of
or encumber any shares of Class A

                                       41
<PAGE>
Common Stock without the prior written approval of the Company, and any  attempt
to  do so  without such prior  approval will be  null and void.  The Company may
condition its approval  of a transfer  of any  shares of Class  A Common  Stock,
other than by sale by an employee or director of, or a consultant to the Company
or  by a  person who acquired  such shares  other than by  purchase, directly or
indirectly, from an  employee or director  of, or a  consultant to the  Company,
upon  the transferee's  agreement to hold  such shares subject  to the Company's
right  to  repurchase  such  shares  upon  the  termination  of  employment   or
affiliation of the employee, director or consultant.

    LAPSE OR WAIVER OF RESTRICTIONS

    All  restrictions upon the shares of Class A Common Stock will automatically
terminate (i) if the Company makes  an underwritten offering of either class  of
its  Common Stock, or securities convertible into any class of its Common Stock,
to the general public or  (ii) if the Company applies  to have any class of  its
Common  Stock, or  securities convertible  into any  class of  its Common Stock,
listed on a national  securities exchange. In addition,  the Board of  Directors
may  waive any or all of  the restrictions on shares of  Class A Common Stock in
such other circumstances as the Board deems appropriate.

  RESTRICTIONS ON CLASS B COMMON STOCK

    Substantially all  of the  presently outstanding  shares of  Class B  Common
Stock  are subject to a right of first refusal on the part of the Company in the
event a stockholder desires to  sell his or her shares  of Class B Common  Stock
other  than in the Limited  Market. Such right is  exercisable by the Company at
the third-party  offer price.  In  addition, all  of the  presently  outstanding
shares  of Class B Common  Stock that were issued  subsequent to October 1, 1981
(other than shares issued subsequent to that date which were distributed out of,
or are presently  held in, the  Profit Sharing Retirement  Plan, Profit  Sharing
Retirement  Plan II, Employee Stock Ownership Plan  and CODA or that were issued
upon the exercise of stock options granted prior to that date) are subject to  a
right  of  repurchase  on  the  part of  the  Company  upon  termination  of the
stockholder's  employment  or  affiliation  with  the  Company.  This  right  is
generally  exercisable by the Company at a price equal to five times the Formula
Price for Class A Common  Stock prevailing at the  time of such termination.  By
their terms, all such restrictions will terminate in the event that either class
of  the Common Stock is listed on  any national securities exchange or is traded
on a  regular basis,  as  determined by  the  Company, in  the  over-the-counter
market.

PREFERRED STOCK

    Pursuant  to the Certificate  of Incorporation, the  Board of Directors may,
from time to time,  authorize the issuance  of one or  more series of  Preferred
Stock  and fix by resolution or resolutions  adopted at the time of issuance the
designations, preferences and relative rights, qualifications and limitations of
each series. Each series of Preferred Stock could, as determined by the Board of
Directors at the time of issuance, rank  senior to the Class A Common Stock  and
Class  B Common Stock  with respect to dividends  and redemption and liquidation
rights.

    The Certificate  of  Incorporation  authorizes the  Board  of  Directors  to
determine,  among other things,  with respect to each  series of Preferred Stock
which may be issued: (i) the dividend rates, conditions and preferences, if any,
in respect of the Class  A Common Stock and Class  B Common Stock and among  the
series  of Preferred Stock,  (ii) whether dividends would  be cumulative and, if
so, the date from which dividends on the series would accumulate, (iii) whether,
and to  what extent,  the holders  of the  series would  have voting  rights  in
addition  to those  prescribed by  law, (iv) whether,  and upon  what terms, the
series would  be convertible  into  or exchangeable  for other  securities,  (v)
whether,  and  upon  what  terms,  the  series  would  be  redeemable,  (vi) the
preference, if  any, to  which the  series would  be entitled  in the  event  of
voluntary  or involuntary liquidation, dissolution or  winding up of the Company
and (vii) whether or not a sinking fund would be provided for the redemption  of
the  series  and,  if so,  the  terms  and conditions  thereof.  With  regard to
dividends and  redemption and  liquidation rights,  the Board  of Directors  may
determine that any particular series of Preferred Stock may rank junior to, on a
parity with or senior to any other series of Preferred Stock.

                                       42
<PAGE>
    Holders  of shares  of Preferred  Stock will  have no  preferential right to
purchase any shares of the Company's  capital stock. The Company has no  present
intention or plan to issue any shares of Preferred Stock.

ITEM 17.  UNDERTAKINGS

    (a) Rule 415 Offering

    Registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being  made,
    a post-effective amendment to the Registration Statement:

           (i)  To include  any prospectus required  by Section  10(a)(3) of the
       Securities Act of 1933;

           (ii) To reflect in the prospectus  any facts or events arising  after
       the  effective date  of the  Registration Statement  (or the  most recent
       post-effective  amendment  thereof)   which,  individually   or  in   the
       aggregate, represent a fundamental change in the information set forth in
       the Registration Statement;

          (iii)  To include any material information with respect to the plan of
       distribution not previously  disclosed in the  registration statement  or
       any material change to such information in the Registration Statement.

        (2)  That  for  the  purpose  of  determining  any  liability  under the
    Securities Act of 1933, each  such post-effective amendment shall be  deemed
    to  be  a  new registration  statement  relating to  the  securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

        (3) To remove from registration  by means of a post-effective  amendment
    any   of  the  securities  being  registered  which  remain  unsold  at  the
    termination of the offering.

    (b) Registrant  hereby  undertakes that,  for  purposes of  determining  any
liability  under the Securities Act of  1933, each filing of Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement shall be deemed to be  a
new  registration statement relating to the  securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial  bona
fide offering thereof.

    (c) Security and Exchange Commission Policy Regarding Indemnification

    Insofar  as indemnification for liabilities arising under the Securities Act
of 1933  may be  permitted to  directors, officers  and controlling  persons  of
Registrant  pursuant to the provisions of Section 145 of the General Corporation
Law  of  Delaware   and  Article  FIFTEENTH   of  Registrant's  Certificate   of
Incorporation,  or otherwise, Registrant has been advised that in the opinion of
the Securities and  Exchange Commission such  indemnification is against  public
policy  as expressed in the Securities  Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other  than
the  payment  by Registrant  of the  expenses  incurred or  paid by  a director,
officer or controlling  person of Registrant  in the successful  defense of  any
action, suit or proceeding) is asserted by such director, officer or controlling
person  in  connection with  the securities  being registered,  Registrant will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent,  submit to a  court of appropriate  jurisdiction the question whether
such indemnification  by  it  is  against public  policy  as  expressed  in  the
Securities Act and will be governed by the final adjudication of such issue.

    (d) Deregistration of Certain Previously Registered Shares

    Pursuant  to Registrant's undertaking to remove from registration any of its
registered securities which remain  unsold at the  termination of the  offering,
Registrant  hereby  deregisters  the  number  of  shares  from  the registration
statements and for the purposes indicated in the table below:

Gentlemen:

    I   am  the  Corporate  Vice  President   and  General  Counsel  of  Science
Applications International Corporation (the "Company"). As such, I have acted as
your counsel in connection with the Prospectus of the Company covering the offer
and sale by (i)  the Company of up  to 28,151,000 shares of  its Class A  Common
Stock,  par value  $.01 per share  (the "Class  A Common Stock")  (the shares of
Class A Common Stock being offered by the Company are hereinafter referred to as
the "Company Shares"), which  may be offered and  sold directly by the  Company,
sold  by stockholders through  the limited market maintained  by Bull, Inc. (the
sale of which  may be  attributed to  the Company),  or issued  pursuant to  the
Company's  existing stock  option plans and  the Company's  or its subsidiaries'
other  employee  benefits  plans  (such   plans  are  hereinafter  referred   to
collectively  as the  "Employee Plans")  and (ii)  the Selling  Stockholders (as
defined in the Prospectus) of  up to an aggregate of  209,000 shares of Class  A
Common  Stock (the  "Selling Stockholder  Shares"). The  Company Shares  and the
Selling Stockholder  Shares are  being offered  pursuant to  a Prospectus  which
constitutes  a part of the Registration Statement on Form S-3 (the "Registration
Statement") to  be  filed  with  the Securities  and  Exchange  Commission  (the
"Commission")  on April 14,  1994 under the  Securities Act of  1933, as amended
(the "Securities Act").

    I am generally familiar with the affairs of the Company. In addition, I have
examined and  am  familiar with  originals  or copies,  certified  or  otherwise
identified  to  my satisfaction,  of (i)  the  Registration Statement,  (ii) the
Restated Certificate of Incorporation and Bylaws of the Company as currently  in
effect,  (iii) resolutions adopted  by the Board of  Directors and the Operating
Committee thereof relating to the filing  of the Registration Statement and  the
issuance  of the Company Shares thereunder, (iv) the Employee Plans and (v) such
other documents as I  have deemed necessary  or appropriate as  a basis for  the
opinions  set forth below. In my examination,  I have assumed the genuineness of
all signatures, the legal capacity of  natural persons, the authenticity of  all
documents  submitted to me as originals, the conformity to original documents of
all documents  submitted to  me  as certified  or  photostatic copies,  and  the
authenticity of the originals of such copies.

    Based upon and subject to the foregoing, I am of the opinion that:

    1.   The  Company Shares  that are  being offered  and sold  directly by the
Company have been duly  authorized for issuance  and when certificates  therefor
have  been duly executed, delivered and paid  for, will be legally issued, fully
paid and nonassessable.

    2.  Any  shares of Class  A Common  Stock sold by  stockholders through  the
limited market maintained by Bull, Inc. which are attributed to the Company have
been  duly authorized  for issuance  and legally issued  and are  fully paid and
nonassessable.

    3.  The Company Shares that are being issued pursuant to the Employee  Plans
have been duly authorized for issuance, and when certificates therefor have been
duly  executed,  delivered and  paid for  in  accordance with  the terms  of the
Employee Plans, will be legally issued, fully paid and nonassessable.

    4.  The Selling Stockholder Shares have been duly authorized and are legally
issued, fully paid and nonassessable.
<PAGE>
    I hereby consent to the use of  my name in the Registration Statement  under
the  caption "Legal Opinion" and to the filing  of this opinion as an exhibit to
the Registration Statement. In giving such consent, I do not thereby admit  that
I  come within the category of persons whose consent is required under Section 7
of the Securities Act or the rules and regulations of the Commission thereunder.

                                          Very truly yours,

                                          Douglas E. Scott
