                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION
 
   
    Of the 30,000,000 shares of Class A Common Stock, par value $.01 per share
(the "Class A Common Stock"), of Science Applications International Corporation
(the "Company") offered hereby, 29,823,500 shares may be offered and sold by the
Company and 176,500 shares may be offered and sold by certain directors and
directors emeritus 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 29,823,500 shares of Class A Common Stock offered by the Company are
anticipated to be offered as follows: (i) 923,500 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; (ii) 1,250,000 shares may be issued and delivered to a trustee for
the benefit of employees under the Company's Employee Stock Ownership Plan;
(iii) 1,750,000 shares may be issued and delivered to a trustee for the benefit
of employees under the Company's Cash or Deferred Arrangement; (iv) 1,000,000
shares may be awarded to employees and directors under the Company's 1984 Bonus
Compensation Plan; (v) 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; (vi) 100,000 shares may be issued and
delivered to a trustee for the benefit of employees under the Company's Key
Executive Stock Deferral Plan; (vii) 1,100,000 shares may be offered and sold to
a trustee or agent for the benefit of employees under the Company's 1995
Employee Stock Purchase Plan; (viii) 23,000,000 shares may be issued upon the
exercise of options granted and available to be granted under the Company's
1982, 1992 and 1995 stock option plans; and (ix) 100,000 shares may be issued
and delivered to a trustee for the benefit of employees of Syntonic Technology,
Inc., a wholly-owned subsidiary of the Company ("Syntonic"), under its Syntonic
Technology, Inc. Retirement Savings Plan. 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 and the Retirement Plans, as defined on page 6) 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."

SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.

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 their fair market value determined
pursuant to the formula and valuation process 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
January, April, July and October. 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 following formula
(the "Formula") is used in determining the Formula Price: 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 determination 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 ("W1"), 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 determination ("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 yields a fair market value
for the Class A Common Stock and Class B Common Stock by reflecting existing
securities market conditions relevant to the valuation of such 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
committees administering the Company's and certain of its subsidiaries'
qualified retirement plans (collectively referred to as the "Committee") and
which is relied upon by the Committee and the Board of Directors. The Board of
Directors believes that the valuation process and Formula result in a fair
market value for the Class A Common Stock within a broad range of financial
criteria. See "Market Information -- Price Range of Class A Common Stock and
Class B Common Stock." Since April 12, 1996, the Market Factor has been 1.8.
Prior thereto and since January 12, 1996, the Market Factor was 1.7. The Formula
Price of the Class A Common Stock, expressed as an equation, is as follows:

Common Stock was $102.05.

                                  RISK FACTORS
    
 
   
     Prior to purchasing the Class A Common Stock offered in the Prospectus,
purchasers should carefully consider all of the information contained in the
Prospectus and in particular should carefully consider the following factors:
    
 
   
CONCENTRATION OF REVENUE/DEPENDENCE ON GOVERNMENT CONTRACTS
    
 
   
     Revenues generated from the sale of the Company's Technical Services and
Products (as such terms are defined on page 6) to the U.S. Government as a prime
contractor or subcontractor accounted for 83%, 86% and 88% of revenues in fiscal
years 1996, 1995 and 1994, respectively. U.S. Government spending has declined
in recent years, and the current Congress and presidential administration have
indicated that they intend to further reduce U.S. Government spending. The loss
of a substantial amount of government business could have a material adverse
effect on the Company's operations and financial condition. Although the Company
has made progress in its efforts to diversify into non-governmental business, it
remains heavily dependent upon business with the U.S. Government, and there can
be no assurances that the Company will be successful in expanding its customer
base or that any new customers will place orders for the Company's Technical
Services or Products in amounts comparable to those of the U.S. Government. See
"The Company."
    
 
   
DEPENDENCE ON ACQUISITIONS FOR GROWTH
    
 
   
     A significant portion of the growth in the Company's revenues in the recent
years has been achieved through acquisitions of businesses that complement the
Company's Products and Technical Services. The Company intends to make
additional acquisitions in the future. While the Company has been successful in
identifying and consummating acquisitions in the past, there can be no assurance
that it will be able to continue to make such acquisitions in the future at
prices that it considers reasonable or, if the acquisitions are consummated,
that the Company will be able to integrate the acquired business without
adversely affecting the Company's results of operations and financial condition.
See "The Company."
    
 
   
COMPETITION
    
 
   
     The businesses in which the Company is engaged are highly competitive. The
Company's competitors include larger organizations with substantially greater
financial resources and larger technical staffs, smaller, more highly
specialized entities and the U.S. Government's own in-house capabilities and
federal non-profit contract research centers. The Company's continued success is
dependent upon its ability to provide superior service and performance on a
cost-effective basis. See 1996 10-K, Item 1, "Business -- Competition."
    
 
   
EARLY TERMINATION OF 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. Modification, termination or curtailment of major programs or
contracts of the Company could have a material adverse effect on the results of
the Company's operations. Although such contract and program modifications,
terminations or curtailments have not had a material adverse effect on the
Company in the past, no assurance can be given that they will not have such an
effect in the future. See "Government Contracts."
    
 
   
CONTRACT REVENUES SUBJECT TO AUDITS BY GOVERNMENT AGENCIES
    
 
   
     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.
Substantially all of the Company's indirect contract costs have been agreed upon
through the fiscal year ended January 31, 1991. 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
    
 
                                        3
<PAGE>   6
 
   
adjustments for subsequent years will not result in decreased revenues or
profits for those years. See "Government Contracts."
    
 
   
FIXED PRICE CONTRACT EXPOSURE
    
 
   
     During the fiscal years ended January 31, 1996, 1995 and 1994, 15%, 13% and
12%, respectively, of the Technical Services revenues were from firm fixed-price
type contracts, while the majority of Products revenues in these three years
were derived from such contracts. 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 reduced profits or
losses for particular firm fixed-price contracts. See "Government Contracts."
    
 
   
AT RISK CONTRACT COSTS
    
 
   
     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 Technical Services and Products revenues at
January 31, 1996 were $18,561,000 and $2,025,000, respectively. Although the
Company expects to recover substantially all such costs, no assurance can be
given that the contracts or contract amendments will be received or that the
related costs will be recovered. See "Government Contracts."
    
 
   
ABSENCE OF A PUBLIC MARKET
    
 
   
     There is no public market for the Common Stock. The Company and the
trustees of the Company's and certain of its subsidiaries' employee benefit
plans are currently authorized, but not obligated, to purchase shares of Class A
Common Stock in the Limited Market on any Trade Date (as defined on page 13),
but only if and to the extent that they, in their discretion, determine to make
such purchases. To the extent that purchases by such trustees or the Company are
not sufficient, the ability of stockholders to resell their shares in the
Limited Market will likely be adversely affected. No assurance can be given that
a stockholder desiring to sell all or a portion of his or her shares of the
Class A Common Stock in any trade will be able to do so. See "Market
Information -- The Limited Market."
    
 
   
OFFERING PRICE DETERMINED BY FORMULA
    
 
   
     The offering price and the price at which the Class A Common Stock trades
in the Limited Market are, and subsequent prices will be, determined by means of
the formula and valuation process described in the Prospectus. See "Market
Information -- Price Range of Class A Common Stock and Class B Common Stock."
    
 
   
NO ASSURANCES REGARDING FUTURE RETURNS
    
 
   
     There can be no assurance that the Class A Common Stock will in the future
provide returns comparable to historical returns. See "Market
Information -- Price Range of Class A Common Stock and Class B Common Stock."
    
 
   
NO CASH DIVIDENDS
    
 
   
     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. See "Dividend Policy."
    
 
   
RESTRICTIONS ON CLASS A COMMON STOCK
    
 
   
     Certain of 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 a right of first refusal and a right of
repurchase upon termination of employment or affiliation and other restrictions
on their transferabil-
    
 
                                        4

ity) set forth in the Company's Certificate of Incorporation. See "Description
of Capital Stock -- Common Stock -- Restrictions on Class A Common Stock."
    
 
   
DEPENDENCE UPON KEY PERSONNEL
    
 
   
     The Company's success will depend upon the continued contributions of its
founder, J.R. Beyster, its officers and key personnel, the loss of which could
materially adversely affect the Company's operations. The Company's growth will
depend upon its ability to attract and retain skilled employees and the ability
of its officers and key employees to successfully manage growth. Any failure to
do so could have a material adverse effect on the Company's operations. The
Company has not generally entered into long-term employment contracts with its
officers and key employees. In addition, the Company does not maintain "key man"
life insurance for its officers or key employees.
    
 
   
ANTI-TAKEOVER EFFECTS
    
 
   
     Consistent with and in furtherance of the Company's employee ownership
philosophy, certain provisions of the Company's Certificate of Incorporation and
Bylaws may discourage, delay, or prevent attempts to acquire control of the
Company that are not approved by the Company's Board of Directors. The
provisions may, individually or collectively, have the effect of discouraging
takeover attempts that some stockholders might deem to be in their best
interests, including tender offers in which stockholders might receive a premium
for their shares over the Formula Price, as well as making it more difficult for
individual stockholders or a group of stockholders to elect directors. See
"Description of Capital Stock -- Anti-Takeover Effects."

<PAGE>   8
 
                                  THE COMPANY
 
   
     The Company provides diversified professional and technical services
("Technical Services") and designs, develops and manufactures high-technology
products ("Products"). The Company's Technical Services and Products are
primarily sold to departments and agencies of the U.S. Government, including the
Department of Defense, Department of Energy, Department of Transportation,
Department of Veterans Affairs, Environmental Protection Agency and National
Aeronautics and Space Administration. Revenues generated from the sale of
Technical Services and Products to the U.S. Government as a prime contractor or
subcontractor accounted for 83%, 86% and 88% of revenues in fiscal years 1996,
1995 and 1994, respectively. The balance of the Company's revenues are
attributable to the sales of Technical Services and Products to foreign, state
and local governments, commercial customers and others. See "Risk
Factors -- Concentration of Revenue/Dependence on Government Contracts."
    
 
   
     The percentage of revenues attributable to Technical Services and Products
has remained relatively constant at 93% and 7%, respectively, for fiscal year
1996; 91% and 9%, respectively, for fiscal year 1995; and 92% and 8%,
respectively, for fiscal year 1994. The Company provides Technical Services
primarily in the areas of "National Security," "Environment," "Energy" and
"Other Technical Services," the last 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 gradually declined to 45% of total revenues for fiscal
year 1996. For fiscal year 1996, the Environment, Energy and Other Technical
Services business areas accounted for 13%, 8% and 28%, respectively, of total
revenues.
    
 
   
     A significant portion of the growth in the Company's revenues in recent
years has been achieved through acquisitions of businesses that complement the
Company's Products and Technical Services. Acquisitions of businesses in 1996
were made primarily with issuance of Class A Common Stock and were primarily
financed with cash in fiscal years 1995 and 1994. The Company expects to
continue to acquire businesses and equity interests in other businesses in the
future. While the Company has been successful in identifying and consummating
acquisitions in the past, there can be no assurance that it will be able to
continue to make such acquisitions in the future at prices that it considers
reasonable or, if the acquisitions are consummated, that the Company will be
able to integrate the acquired business without adversely affecting the
Company's results of operations. See "Risk Factors -- Dependence on Acquisitions
for Growth."
    
 
   
     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. The Company's Cash or Deferred Arrangement,
Employee Stock Ownership Plan and certain other retirement plans of the Company
and its subsidiaries are referred to herein collectively as the "Retirement
Plans."
    
 
                              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 generally 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
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
 
                                        6
<PAGE>   9
 
   
terminations of U.S. Government programs or contracts will not have a material
adverse effect on the Company in the future. See "Risk Factors -- Early
Termination of Government Contracts."
    
 
   
     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,
fixed 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 reduced profits or losses for particular
firm fixed-price contracts. See "Risk Factors -- Fixed Price Contract Exposure."
    
 
   
     During the fiscal years ended January 31, 1996, 1995 and 1994,
approximately 57%, 64% and 65%, respectively, of Technical Services revenues
were derived from cost-reimbursement type contracts and approximately 15%, 13%
and 12%, 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 in these three years were 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 revenues, exclusive of
related fees, at January 31, 1996 were approximately $18,561,000. Unbilled
receivables in this category which were included in the Products revenues,
exclusive of related fees, at January 31, 1996 were approximately $2,025,000.
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. See "Risk Factors -- At Risk
Contract 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.
Substantially all of the Company's indirect contract costs have been agreed upon
through the fiscal year ended January 31, 1991. 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. See "Risk Factors -- Contract Revenues Subject to Audits by Government
Agencies."
    
 
   
     The Company is from time to time subject to certain U.S. Government
inquiries and investigations of its business practices. The Company does not
anticipate any action as a result of such inquiries and investigations that
would have a material adverse effect on its consolidated financial position or
results of operations or its ability to conduct business.
    
 
                      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 potential 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 and Directors
    
 
   
     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 a specified number of the
shares of Class A Common Stock offered hereby in the Limited Market. 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."
    
 
  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 Internal Revenue
Code of 1986, as amended (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 Sections 401(k) and (m) 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 amounts
deferred to his or her CODA account. Effective January 1, 1995, the Company's
matching contribution to employees hired on or after such date vest in
accordance with a vesting schedule and other vesting rules set forth in the
CODA, while the Company's matching contributions for employees hired before such
date remain fully vested. 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."
    
 
  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 CODA. 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 from 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."

  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
Bonus Compensation Plan. Pursuant to the Certificate of Incorporation, all
shares of Class A Common Stock awarded pursuant to 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 "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"), which are 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 or affiliation. See "Employee Benefit Plans -- Stock Compensation
Plans" and "Description of Capital Stock -- Common Stock -- Restrictions on
Class A Common Stock."
    
 
   
  Key Executive Stock Deferral Plan
    
 
   
     Effective January 4, 1996, the Company adopted the Key Executive Stock
Deferral Plan ("Stock Deferral Plan"), which provides a vehicle for directors
and certain key executives to defer bonuses and directors' fees. Deferred
amounts are invested in shares of Class A Common Stock in a trust established by
the Company, which trust is similar to the trust established for the Stock
Compensation Plans. See "Employee Benefit Plans -- Stock Compensation Plans." If
the deferred bonus was a vesting bonus under the Bonus Compensation Plan, the
vesting schedule is applied to the participant's interest in the trust
established under the Stock Deferral Plan. Distribution of a participant's
interest in the trust established under the Stock Deferral Plan will be made
upon the participant's termination of affiliation or employment with the
Company. Generally, distributions will be made in a lump sum, except in the case
of distributions following a participant's retirement date, which the
participant may elect to receive in a lump sum (or in installments over a five-
or ten-year period). All distributions will be made in shares of Class A Common
Stock unless the committee administering the Stock Deferral Plan determines, in
its sole discretion, that such distribution is impossible or would create an
adverse impact on the Company.
    
 
   
     Pursuant to the Certificate of Incorporation and agreements executed by
participants as a condition to participation in the Stock Deferral Plan, all
shares of Class A Common Stock distributed from the trust associated with the
Stock Deferral 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,
as well as other restrictions set forth in such agreements. See "Employee
Benefit Plans -- Key Executive Stock Deferral Plan" and "Description of Capital
Stock -- Common Stock -- Restrictions on Class A Common Stock."

  1995 Employee Stock Purchase Plan
    
 
   
     The Company maintains the 1995 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;
however, the Company's contributions to the purchase price may range from 0% to
15% as determined by the Stock Purchase Committee from time to time. All shares
purchased pursuant to the Stock Purchase Plan will be distributed prior to any
record date established by the Company for a stockholder vote 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, 1998.
See "Employee Benefit Plans -- Stock Purchase Plan" and "Description of Capital
Stock -- Common Stock -- Restrictions on Class A Common Stock."
    
 
  Stock Option Plans
 
   
     Pursuant to the Company's 1995 Stock Option Plan, the Company grants stock
options to certain of its employees, consultants and directors. Although the
Company's 1982 and 1992 Stock Option Plans terminated on June 10, 1992 and July
31, 1995, respectively, and no additional stock options can be granted under
those Plans, certain stock options previously granted under such plans remain
outstanding. Stock options under the 1995 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 Company's right of first refusal and the Company's right
of repurchase upon termination of employment or affiliation. The 1995 Stock
Option Plan authorizes grants of both non-qualified stock options and incentive
stock options. Under the terms of the 1995 Stock Option Plan, the aggregate
number of shares subject to options granted to any individual may not exceed
500,000 shares. See "Employee Benefit Plans -- Stock Option Plans" and
"Description of Capital Stock -- Common Stock -- Restrictions on Class A Common
Stock."
    
 
   
  Syntonic Technology, Inc. Retirement Savings Plan
    
 
   
     The Company's wholly-owned subsidiary, Syntonic Technology, Inc.
("Syntonic"), maintains the Syntonic Technology, Inc. Retirement Savings Plan
("Syntonic Savings Plan") which is intended to be qualified under Sections
401(a) and (k) of the Code. Generally, all employees of Syntonic who have
completed 12 months of employment and 1,000 hours of service with Syntonic
during one of the applicable 12-month computational periods are eligible to
participate as of the next quarterly entry date, except for supplemental
(temporary) employees and employees in groups or units designated as ineligible.
The Syntonic Savings Plan permits a participant to elect to defer, for federal
income tax purposes, a portion of his or her annual compensation on a pre-tax
basis and to have such amount contributed directly by Syntonic to the Syntonic
Savings Plan for his or her benefit. Subject to approval, a participant may also
make after-tax voluntary contributions to the Syntonic Savings Plan. Syntonic
may make a matching contribution for the benefit of those participants who have
elected to make pre-tax salary deferral contributions to the Syntonic Savings
Plan. The amount of matching contribution currently is equal to 50% of a
participant's pre-tax contributions that do not exceed 4% of the participant's
compensation. In addition, Syntonic may, but is not obligated to, make
additional matching contributions or a profit sharing contribution in an amount
determined by Syntonic's Board of Directors. Any profit sharing contributions
will be allocated in proportion to the compensation of each participant who
completes 1,000 or more hours of service during the plan year and is employed on
the last day of the plan year. All plan contributions are made in cash. Each
participant is at all times 100% vested in his or her pre-tax and after-tax
contributions. A participant becomes vested in employer matching and profit
sharing contributions in accordance with a vesting schedule and other vesting
rules set

forth in the Syntonic Savings Plan. Benefits are payable in cash within certain
specified time periods following a participant's termination of employment.
Certain in-service withdrawals are permitted under rules set forth in the
Syntonic Savings Plan. See "Employee Benefit Plans -- Syntonic Savings Plan."
    
 
CLASS A COMMON STOCK OFFERED BY THE SELLING STOCKHOLDERS
 
   
     The Selling Stockholders may sell up to an aggregate of 176,500 shares of
the Class A Common Stock being offered hereby in the Limited Market or
otherwise. The Selling Stockholders will not be treated more favorably than
other stockholders participating in the Limited Market and, like all
stockholders selling shares in the Limited Market (other than the Company and
the Retirement Plans), will pay the Company's wholly-owned, broker-dealer
subsidiary, Bull, Inc., a commission equal to two percent of the proceeds from
their sales. See "Market Information -- The Limited Market." Pursuant to the
Certificate of Incorporation, all of the shares of Class A Common Stock
purchased in the Limited Market from the Selling Stockholders 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 "Description of Capital
Stock -- Common Stock -- Restrictions on Class A Common Stock."
    
 
   
     The following table sets forth information as of April 19, 1996 with
respect to the number of shares of Class A Common Stock owned by each Selling
Stockholder (including shares issuable upon the exercise of outstanding stock
options which are exercisable within 60 days of such date and shares allocated
to such person's accounts as of such date under the Company's employee benefit
plans) and as adjusted to reflect the sale of all shares of Class A Common Stock
being offered hereby by such Selling Stockholder. The table does not give effect
to the sale of any shares of Class A Common Stock being offered by the Company.
Each of the Selling Stockholders has been a director, director emeritus and/or
officer of the Company for the past three years. Except as indicated below, all
the shares are owned of record and beneficially.

                               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 broker-dealer 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 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, directors and
consultants 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
Employee Stock Ownership Plan, CODA, Stock Purchase Plan, Stock Compensation
Plans, Key Executive Stock Deferral Plan and the Syntonic Savings Plan 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 and
the Retirement Plans) 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 in the
Limited Market on any Trade Date is greater than the aggregate number of shares
sought to be purchased by authorized buyers and the Company, offers by
stockholders to sell 500 or less shares 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 such stockholder) will be accepted first. Offers to sell 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. In fiscal years 1996 and 1995, the Company purchased 33,372 and
279,668 shares, respectively, in the Limited Market. The Company's purchases in
fiscal years 1996 and 1995 accounted for 2% and 16%, respectively, of the total
shares purchased by all buyers in the Limited Market during those years.
    
 
   
     During the 1996 and 1995 fiscal years, the trustees of the CODA, 1993
Employee Stock Purchase Plan, 1995 Employee Stock Purchase Plan and the Syntonic
Savings Plan purchased an aggregate of 1,045,893 shares and 1,065,741 shares,
respectively, in the Limited Market. These purchases accounted for approximately
69% and 61% of the total shares purchased by all buyers in the Limited Market
during fiscal years 1996 and 1995, 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. No assurance can be given that a stockholder
desiring to sell all or a portion of his or her shares of the Company's Class A
Common Stock in any trade will be able to do so. See "Risk Factors -- Absence of
a Public Market."
    
 
                                       13
<PAGE>   16
 
   
     The Company received a no-action letter from the SEC 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
employees, directors 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.
    
 
   
     The Company and the Employee Stock Ownership Plan have completed one Tender
Offer pursuant to which the Employee Stock Ownership Plan purchased an aggregate
of 700,444 shares of Class A Common Stock from 186 Outside Stockholders on
November 20, 1992. The Company has not yet determined whether it will commence a
Tender Offer during calendar year 1996. 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 fair market value of the Class A Common Stock is established pursuant
to the valuation process described below, which uses the Formula set forth on
the cover page of this Prospectus to determine the Formula Price at which the
Class A Common Stock trades in the Limited Market. The Formula Price is reviewed
by the Board of Directors at least four times each year, generally in
conjunction with Board of Directors meetings which are currently scheduled for
January, April, July and October. Pursuant to the Certificate of Incorporation,
the price applicable to shares of Class B Common Stock is equal to five times
the Formula Price. See "Risk Factors -- Offering Price Determined by Formula."
    
 
   
     The following formula is used in determining the Formula Price: 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 determination 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 ("W1") 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 determination ("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 yields a fair market value
for the Class A Common Stock and the Class B Common Stock by reflecting existing
securities market conditions relevant to the valuation of such stock. In
establishing the Market Factor, the Board of Directors considers the performance
of the general securities markets and relevant industry groups, the financial
performance of the Company versus comparable public companies, general economic
conditions, input from an independent appraisal firm and other relevant factors.
The Market Factor is generally reviewed quarterly by the Board of Directors in
conjunction with an appraisal which is prepared by the independent appraisal
firm for the Committee and which is relied upon by the Committee and the Board
of Directors. The Market Factor, as determined by the Board of Directors,
remains in effect until subsequently changed by the Board of Directors. The
Formula Price of the Class A Common Stock, expressed as an equation, is as
follows:

<PAGE>   17
 
   
     The Formula was modified by the Board of Directors on April 14, 1995 to
delete a limitation that the Formula Price 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 a price revision is to occur (the "Book
Value Floor"). The modification was intended to ensure that the Formula Price
would be a fair market value as required by law. The Formula Price has always
exceeded the Book Value Floor, and the Book Value Floor has never been used to
establish the Formula Price. With the exception of this modification, the
Formula has not been modified by the Board of Directors since March 23, 1984.
    
 
   
     The following table sets forth information concerning the Formula Price for
the Class A Common Stock, the applicable price for the Class B Common Stock and
the Market Factor in effect for the periods beginning on the dates indicated.
There can be no assurance that the Class A Common Stock or the Class B Common
Stock will in the future provide returns comparable to historical returns. See
"Risk Factors -- No Assurances regarding Future Returns."

     The Board of Directors believes that the valuation process and Formula
result 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
law.
    
 
                                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. See "Risk Factors -- No
Cash Dividends."
    
 
                                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 potential 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 $105,500,
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 923,500 of the shares registered hereby are offered by
stockholders (other than the Selling Stockholders) for sale in the Limited
Market and such sales may be attributed to the Company for
    
 
                                       15
<PAGE>   18
 
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 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
 
     The Profit Sharing Retirement Plan represents a consolidation, effective as
of January 1, 1995, of the former Profit Sharing Retirement Plan II and the
Profit Sharing Retirement Plan. The Profit Sharing Retirement Plan II was itself
a consolidation, effective January 1, 1992, of the former TSC Profit Sharing
Retirement Plan and the SAIC COMSYSTEMS Profit Sharing Retirement Plan.
Participants in the Profit Sharing Retirement Plan are not permitted to direct
investment of their account balances into Company Stock or a Company Stock Fund.
However, participants in the former Profit Sharing Retirement Plan II who have a
portion of their account balances invested in a Company Stock Fund maintained
within the Plan are permitted to leave that portion of their account balances
invested in the Company Stock Fund, but may not add to that investment option
with any transfers out of other investment options or with respect to any new
allocations of Company contributions to the Profit Sharing Retirement Plan.
 
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, 1995, there were
approximately 17,800 participants in the CODA.
    
 
  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, totaled
approximately $59,133,000 for the Plan Year ended December 31, 1995. 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 1996, the limitation is $9,500. 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 matching contribution accounts
of those participants (i) who have elected to defer a portion of their
compensation, (ii) who are not employees of a group or unit designated as
ineligible to receive a matching contribution and (iii) who have attained the
age of 21 and have completed 12 months of employment and 850 Hours of Service
with the Company during one of the applicable 12-month computational periods.
For the Plan Year ended December 31, 1995, the Company contributed 30% of the
first $2,000 of a participant's compensation deferred under the CODA and 15% of
such
    
 
                                       16
<PAGE>   19
 
   
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, 1995 was $9,431,000. The
Company may also make additional contributions to the CODA in order to comply
with Sections 401(k) and (m) of the Code. For the Plan Year ended December 31,
1995, the Company made additional contributions of $2,104,000 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 and the Employee
Stock Ownership Plan, as applicable.
 
     An Eligible Employee may transfer a rollover contribution from another
qualified retirement plan to the trust fund maintained for the CODA 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
established by the Committee and currently available to participants in the CODA
consist of the Company Stock Fund and thirteen Vanguard Mutual Funds managed by
the Vanguard Group of Investment Companies ("Vanguard"), located in Valley
Forge, Pennsylvania. The Company's matching contributions for the Plan Year
ended December 31, 1995 were (and the matching contributions for the Plan Year
ending December 31, 1996) 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 (other
than matching contributions) allocated or apportioned among the different
investment alternatives. Separate CODA 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. No commissions are payable with respect to
acquisitions or dispositions of Vanguard fund shares.
    
 
     Investments in the Company Stock Fund (other than the non-exchangeable
matching 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."
 
   
     The following table summarizes, as of the dates indicated, the investment
performance of the Company Stock Fund and of each of Vanguard's thirteen mutual
funds available for investment for the last five years. In the case of the
Intermediate Term Corporate Portfolio, since it was established in 1993, and the
Lifestrategy Funds, since they were established in 1994, the table only reflects
the period these funds have been in existence. The summary is based on an
initial investment of $100 in each investment alternative as of December 31,
1991, except for the Intermediate Term Corporate Portfolio which is as of
December 31, 1993 and the Lifestrategy Funds which are as of December 31, 1994.

  Vesting
 
   
     Under the CODA as currently in effect, each participant is, at all times,
100% vested in amounts deferred to his or her CODA account. Effective as of
January 1, 1995, the Company's matching contribution for employees hired on or
after such date 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 in his or her Company matching account becomes fully vested after the
participant is credited with six Years of Service. A participant's interest in
such account 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 age 59 1/2, permanent disability, judicial
declaration of mental incompetence or death, while employed by the Company. The
Company's matching contribution for employees hired on or prior to December 31,
1994 remains fully vested.
    
 
  Loans
 
   
     Loans are available to participants from the CODA account. 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 of the Company's qualified retirement plans (loans
from the 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 minimum loan amount is $500. 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 and vested interest in the matching contribution 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 and matching contribution 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 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 and matching
contribution 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 entire interest in his
or her CODA account and vested interest in the matching contribution 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 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(s) (i) approximately 120 days after the end
    
 
                                       21
<PAGE>   24
 
   
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. The CODA has been amended,
subject to IRS approval, to require participants in the CODA whose employment
with the Company has terminated to transfer any account balances invested in the
Company Stock Fund to other CODA investment choices. It is anticipated that such
change will be implemented effective January 1, 1997.
    
 
   
     If a participant who was only partially vested in his or her matching
contribution 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 from such account 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. Except in the case of a 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 only be made 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 Company retirement plan 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 the
CODA following the hardship withdrawal.
    
 
     All distributions, including withdrawals, from the CODA are paid in cash.
 
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 Class A Common Stock and Class B 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 were 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 of groups or units
designated as ineligible. As of December 31, 1995, there were approximately
15,500 participants in the Employee Stock Ownership Plan.
    
 
  Contributions, Allocations and Forfeitures
 
   
     For the Plan Year ended December 31, 1995, the Company contributed
approximately $10,260,000 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
    
 
                                       22
<PAGE>   25
 
Sharing Retirement Plan, 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 are eligible to receive
such contributions in the ratio which each such participant's eligible
compensation bears to the total eligible compensation of all such participants.
Eligible participants are participants who (i) complete 850 Hours of Service
during the Plan Year and (ii) either are employed on the last day of the Plan
Year or whose employment terminated during the Plan Year as a result of death,
retirement, disability or involuntary layoff (other than for cause).
Forfeitures, if any, of the nonvested portion of terminated participants'
accounts are 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. However, effective January 1, 1995, allocations of Company
contributions and forfeitures will be made separately to different Fringe Rate
groups designated by the Company, such that participants in one Fringe Rate
group will receive a different allocation (as a percentage of compensation) than
participants in another Fringe Rate group.
    
 
  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--CODA--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 CODA.
    
 
     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
 
                                       23
<PAGE>   26
 
   
investment exchanges. Accordingly, investment exchanges of participants'
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 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 to participants from the Employee Stock Ownership Plan.
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 (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 minimum loan amount is $500. 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
    
 
                                       24
<PAGE>   27
 
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 February 9, 1990, with respect to any shares of 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 shares of Class A
Common Stock or Class B Common Stock are 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 would 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) from 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. However, a participant may, under rules established by the
Committee, make one withdrawal from the Employee Stock Ownership Plan after
attaining age 62, even if the participant has not terminated employment. 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
Company retirement plan loans.

GENERAL PROVISIONS OF THE PROFIT SHARING RETIREMENT PLAN, EMPLOYEE STOCK
OWNERSHIP PLAN AND CODA
 
     The Profit Sharing Retirement Plan, 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. The $30,000 limit will be adjusted for cost of living in
accordance with rules of the Secretary of the Treasury.
 
  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,
J. Collymore, W.M. Layson, L.O. Louden, A.H. Park, J.M. Preimesberger, W. Reed,
W.A. Roper, Jr. and M.W. Tobriner (Chairman). 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
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 Plan.
 
  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 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 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 pay calls or assessments imposed on the holder
thereof and 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 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,
for any reason and without prior notice, 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
 
                                       27
<PAGE>   30
 
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, including if the Company ceases to exist as an
entity in the event it merges into or with any other corporation. 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.
 
          (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
 
                                       28
<PAGE>   31
 
     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 and the Profit Sharing Retirement
     Plan 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 1/2 when 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 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 non-deductible contributions (made to those Plans
     which previously permitted the participant to make voluntary non-deductible
     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
    
 
                                       29
<PAGE>   32
 
   
     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 1996, the limit is $150,000.
     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 1996, the limit is
     $750,000. 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.
    
 
   
     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 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
1996, the adjusted limit is $9,500.
    
 
     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 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.
    
 
   
SYNTONIC SAVINGS PLAN
    
 
   
     The Syntonic Savings Plan became effective January 1, 1986. The Syntonic
Savings Plan is in the process of being amended to permit participants to direct
that a portion of their account balances be invested in a Company Stock Fund
under rules established by Syntonic. The amendment (the "Amendment") will be
implemented on July 1, 1996.
    
 
   
  Eligibility and Participation
    
 
   
     Generally, all employees (other than supplemental (temporary) employees and
employees covered under a collective bargaining agreement) who have completed
1,000 hours of service during one of the 12-month computational periods are
eligible to participate as of the next quarterly entry date. As of December 31,
1995, there were approximately 300 participants in the Syntonic Savings Plan.
    
 
                                       30
<PAGE>   33
 
   
  Contributions and Allocations
    
 
   
     The Syntonic Savings Plan permits a participant to elect to defer a portion
of such participant's compensation and to have such amount contributed on a
pre-tax basis by Syntonic to the participant's account in the Syntonic Savings
Plan.
    
 
   
     A participant may also make voluntary (after-tax) contributions to the
Syntonic Savings Plan. Amounts deferred by participants as pre-tax contributions
under Section 401(k) of the Code or voluntary after-tax contributions, including
rollovers from qualified plans, totaled approximately $777,200 for the Plan Year
ended December 31, 1995. The maximum amount a participant may defer as a pre-tax
contribution is determined by Syntonic so as to satisfy certain tests imposed
under the Code, but in no event may exceed $9,500 per year (for 1996), which
amount is adjusted for cost-of-living under rules prescribed by the Secretary of
the Treasury. Subject to Syntonic's approval, voluntary after-tax contributions
of from 1% to 5% of compensation are permitted. In addition to amounts deferred
or contributed by participants, Syntonic may make a matching contribution to the
accounts of participants who have elected to make pre-tax contributions under
Section 401(k) of the Code to the Syntonic Savings Plan. In addition, Syntonic
may, but is not required to, make a discretionary profit sharing contribution to
the accounts of participants who complete 1,000 or more hours of service during
the Plan Year and are employed on the last day of the Plan Year. For the Plan
Year ended December 31, 1995, Syntonic contributed 50% of each participant's
pre-tax contributions to the extent those pre-tax contributions did not exceed
4% of the participant's compensation. The amount of matching contributions made
by Syntonic for the Plan Year ended December 31, 1995 was $204,200. No
discretionary profit sharing contribution was made by Syntonic for the Plan Year
ended December 31, 1995.
    
 
   
     Syntonic's contributions to the Syntonic Savings Plan are made by the due
date (including extensions) for the Company's federal income tax return for the
applicable year except contributions arising from participant's pre-tax or
after-tax contributions, which must be made within 30 days of the date the
participant otherwise would have received the deferred amount. Syntonic's
practice has been to make matching contributions monthly.
    
 
   
     A participant's pre-tax contributions to the Syntonic Savings Plan will not
reduce his or her compensation for purposes of receiving allocations of any
profit sharing contributions under the Syntonic Savings Plan.
    
 
   
     An eligible employee may transfer a rollover contribution from another
qualified retirement plan to the trust fund maintained for the Syntonic Savings
Plan pursuant to applicable regulations and procedures established by Syntonic.

  Investment of Funds
    
 
   
     The Syntonic Savings Plan currently permits participants to direct
investment of their account balances among nine Vanguard Mutual Funds and will,
upon effectiveness of the Amendment, permit investments in the Company Stock
Fund. The Vanguard funds offered are: Money Market Reserves -- Prime Portfolio,
GNMA Portfolio, Index Trust-500 Portfolio, Short Term Federal Portfolio,
Wellesley Income Fund, International Growth Portfolio, Long-Term Corporate
Portfolio, Wellington Fund and Windsor II Fund. The performance tables for the
first six funds and the Company Stock Fund can be found at pages 17 and 18. See
"Employee Benefit Plans -- CODA." The following table summarizes, as of the
dates indicated, the investment performance of the latter three funds for the
last five years.

     Participants may elect at such time, in such manner and subject to such
restrictions as Syntonic may specify, to have contributions (other than
discretionary profit sharing contributions) allocated or apportioned among the
different investment alternatives. Separate accounts are established for each
investment alternative selected by a participant and each such account is valued
separately. Syntonic, 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
Syntonic may specify. No commissions are payable with respect to acquisitions or
dispositions of Vanguard fund shares.

     Upon effectiveness of the Amendment, pre-tax contributions made under
Section 401(k) of the Code and voluntary (after-tax) contributions invested by
participants in the Company Stock Fund may be exchanged into other investment
choices only on a Trade Date. Syntonic's matching contributions which are
invested by participants in the Company Stock Fund may not be exchanged for
another investment alternative. Discretionary profit sharing contributions, if
any, made by Syntonic are currently intended to be invested in the Company Stock
Fund, which contributions may not be exchanged for another investment
alternative. Balances from Vanguard investments may not be exchanged into the
Company Stock Fund except that active participants will be given a limited
opportunity upon implementation of the Amendment to exchange up to 50% of
current Vanguard investment balances into the Company Stock Fund. It is the
current policy of Syntonic to keep all amounts in the Company 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. 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 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 shares may be offered 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 Syntonic Savings Plan as currently in effect, each participant
is, at all times, 100% vested in his or her pre-tax and after-tax contributions
accounts. Accounts containing employer matching contributions and profit sharing
contributions vest 20% per year of service, as defined in the Syntonic Savings
Plan. A participant's interest in such accounts also becomes fully vested upon
attaining age 65, upon permanent disability or death of the participant.
    
 
   
  Loans
    
 
   
     Loans are available from a participant's account in the Syntonic Savings
Plan in an amount up to the lesser of $50,000 (reduced by the highest value of
any outstanding loan balance in the preceding 12 months) or 50% of a
participant's vested account balance. Loans are limited to specified hardships
as approved by Syntonic. The minimum loan amount is $1,000 and only one loan may
be outstanding at any time. A loan processing fee of $100 is charged for each
loan. Loans are funded from the investment funds designated by the participant,
but a participant may not borrow from the Company Stock Fund or more than 75% of
a participant's Equity Fund balance. Loans must (i) bear a reasonable rate of
interest, (ii) be adequately secured by the participant's account(s) balance,
(iii) state the date upon which the loan must be repaid, which in any event may
not exceed five years from the date the loan is made, unless the proceeds are
used for the purchase of a principal residence and (iv) be amortized with level
payments, made not less frequently than quarterly, over the term of the loan.
Loans must be repaid through payroll deductions. If a participant's employment
terminates for any reason when the participant has an outstanding loan balance,
the unpaid loan balance will be taken from the participant's account and treated
as a distribution to the participant. Principal and interest payments on the
loan are allocated to the participant's account(s) in accordance with the
current investment choices of the participant.
    
 
   
  Distributions and Withdrawals
    
 
   
     If a participant's employment with Syntonic terminates on or after the date
on which the participant attains retirement age (65, or 55 with 5 years of
service), the participant is entitled to receive a single distribution of his or
her entire interest in his or her retirement account(s) as soon as practicable
following the date of such termination. In the event a participant dies while
employed by Syntonic, Syntonic will direct the Trustee to make a single
distribution of the participant's entire interest in his or her account(s) to
    
 
                                       33
<PAGE>   36
 
   
the participant's spouse. Alternatively, if such spouse has given proper consent
or if the participant has no spouse, Syntonic will direct the Trustee to make a
single distribution of the deceased participant's entire interest to the
Beneficiary designated by the participant. In the event Syntonic determines that
the participant has suffered a permanent disability while employed by Syntonic,
Syntonic will direct the Trustee to make a single distribution of the
participant's entire interest in his or her account(s) to the disabled
participant.
    
 
   
     If a participant's employment with Syntonic terminates, other than by
reason of permanent disability or death, prior to the date on which the
participant attains retirement age, the participant's entire interest in his or
her pre-tax and after-tax contributions account(s) and vested interest in the
matching contribution and profit sharing account(s) 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 defer distribution of his or her account(s), but not beyond
retirement age, until any time following his or her termination of employment
but not later than age 70 1/2.
    
 
   
     If a participant who was only partially vested in his or her matching
contribution or profit sharing 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 from such account 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. Except in the case of
qualifying hardship, no withdrawals may be made from a participant's account(s)
prior to his or her termination of employment unless and until he or she attains
the age of 59 1/2, except for withdrawals of after-tax contributions. Any
withdrawals made after age 59 1/2, any withdrawals of after-tax contributions
and any hardship withdrawals may be made only once in any 12-month period. In
the absence of a qualified domestic relations order to the contrary, a
participant's interest in the Syntonic Savings Plan may not be voluntarily or
involuntarily assigned or hypothecated, except for the purpose of qualified
loans. Syntonic has established procedures for hardship withdrawals, including
(i) definition of qualifying hardships, (ii) requirements for having first
withdrawn all voluntary after-tax contributions and having received the maximum
loans available under all plans maintained by an Affiliated Company, and (iii)
requirement for a 12-month suspension from making elective after-tax deferrals
into the Syntonic Savings Plan following the hardship withdrawal.
    
 
   
  Additional Provisions of the Syntonic Savings Plan
    
 
   
     The Syntonic Savings Plan contains provisions similar to the Profit Sharing
Retirement Plan, Employee Stock Ownership Plan and CODA with respect to
Contribution Limitations, Pass-Through Voting and Tendering of Class A Common
Stock, Account Statements, Amendment and Termination. In addition, the
description of "ERISA" and "Federal Income Tax Consequences" applicable to the
Profit Sharing Retirement Plan, Employee Stock Ownership Plan and CODA applies
equally to the Syntonic Savings Plan. See "Employee Benefit Plans -- General
Provisions of the Profit Sharing Retirement Plan, Employee Stock Ownership Plan
and CODA."
    
 
   
     The Plan Administrator of the Syntonic Savings Plan is Syntonic, and the
trustee of the Syntonic Savings Plan is State Street Bank and Trust Company.
Syntonic may establish a committee to which it may delegate specified duties in
connection with the administration of the Syntonic Savings Plan. Syntonic has
entered into an agreement with Vanguard, pursuant to which Vanguard performs
specified administrative services for the Syntonic Savings Plan, principally
related to accounting and recordkeeping. Vanguard's fees for these
administrative services are paid by Syntonic.
    
 
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 Bonus Compensation Plan was amended and restated in its
current form on April 2, 1991. The Plan provides for the distribution of bonuses
in cash, shares of Class A Common Stock or both. The Bonus Compensation Plan is
not subject to ERISA and is not intended to be qualified under Section 401(a) of
the Code.
    
 
                                       34
<PAGE>   37
 
  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 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 and the
Compensation Committee of 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, 1996, a total of 8,631 individuals received an
aggregate of approximately $15,825,000 in cash bonuses and 587,000 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 the recipient 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.
 
                                       35
<PAGE>   38
 
     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 recipient'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
recipient's consent, affect any bonus award previously made to such recipient.
    
 
  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), L.A. Kull and J.B. Wiesler. 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 entered 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
 
                                       36
<PAGE>   39
 
   
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 Stock Compensation Plans. 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 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-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.
 
  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
(along with other general creditors of the Company) whose only recourse is
against the assets of the Company, including the assets of the Trust. The assets
of the Trust are not guaranteed or insured by any party, including the Company.
 
   
     The shares of Class A Common Stock held in the Trust are voted in the same
proportion as the other shareholders of the Company vote their shares of Class A
Common Stock and Class B Common Stock. In the event of a tender offer for the
Class A Common Stock and Class B Common Stock, the Trust Agreement calls for the
Trustee to tender the shares of Class A Common Stock held in the Trust if more
than 50% of the shares of Class A Common Stock and Class B Common Stock held
outside the Trust are tendered by the shareholders of 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
 
                                       37
<PAGE>   40
 
   
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 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 apply or continue to apply.
 
  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 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.
 
   
KEY EXECUTIVE STOCK DEFERRAL PLAN
    
 
   
     Effective January 4, 1996, the Company adopted the Key Executive Stock
Deferral Plan (the "Stock Deferral Plan"). In connection with the Stock Deferral
Plan, the Company entered into a trust agreement with State Street Bank and
Trust Company, as Trustee, establishing a trust which will hold the accounts of
participants in the Stock Deferral Plan and which is substantially identical in
its terms with the Trust established under the Stock Compensation Plans. See
"Employee Benefit Plans -- Stock Compensation Plans."
    
 
   
     The provisions of the Stock Deferral Plan relating to the trust established
under the Stock Deferral Plan, and the description of the Federal Income Tax
Consequences, Amendment and Termination and Administration are substantially the
same as those described above for the Stock Compensation Plans. See "Employee
Benefit Plans -- Stock Compensation Plans."
    
 
                                       38
<PAGE>   41
 
   
     Eligibility under the Stock Deferral Plan is limited to directors of the
Company and certain key executives as determined by the Deferral Authority under
the Plan. Eligible participants may defer up to 100% of bonuses and director
fees, if applicable. Similar to the Stock Compensation Plans, a participant's
interest in the trust established under the Stock Deferral Plan will be in the
form of Share Units, and will be subject to a vesting schedule to the extent the
deferred bonus would have been subject to a vesting schedule under the Bonus
Compensation Plan.
    
 
   
     Distribution of participant's interest in the trust established under the
Stock Deferral Plan will be made in a lump sum upon termination of affiliation
or employment, except that a participant may elect five- or ten-year installment
payments for distributions following his or her retirement date. All
distributions will be made in shares of Class A Common Stock, unless the
Committee determines that such distribution would be impossible or would create
adverse impact on the Company.
    
 
   
     It is intended that the Stock Deferral 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. The treatment of the Stock
Deferral Plan is intended to be similar to the Management Stock Compensation
Plan. See "Employee Benefit Plans -- Stock Compensation Plans -- ERISA."
    
 
STOCK PURCHASE PLAN
 
  General
 
   
     The Stock Purchase Plan was approved by the stockholders of the Company at
the 1995 Annual Meeting of Stockholders and became effective on July 14, 1995.
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 3% 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 1,500,000 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) has been authorized for issuance by the
Company as newly issued shares under the Stock Purchase Plan. For the fiscal
year ended January 31, 1996, 132,701 shares of Class A Common Stock were
purchased for the accounts of 2,179 participants in the Stock Purchase Plan.
    
 
                                       39
<PAGE>   42
 
   
     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 5% is currently being paid by the Company. Under the Stock Purchase Plan,
the Company's contribution to the purchase price may range from 0% to 15%, as
determined by the Stock Purchase Committee from time to time.
    
 
  Distribution and Withdrawals
 
   
     Shares of Class A Common Stock acquired under the Stock Purchase Plan will
be distributed to each participant prior to any record date established by the
Company for a stockholder vote 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 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
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 from the Stock Purchase Plan and receive the
money held in their stock purchase accounts at any time prior to the acquisition
of shares of Class A Common Stock therewith. A participant who has withdrawn
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 unless required by law.
    
 
  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
or (ii) 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, 1998.
    
 
  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. Jenings, 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. Members of the Stock Purchase Committee are
eligible to participate in the Stock Purchase Plan.
    
 
  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
 
                                       40
<PAGE>   43
 
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 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 early disposition of the shares.
 
   
     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 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 ("ISOs") 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 stock
options due primarily to the favorable tax benefits received by the Company upon
the exercise of such options. See "General Provisions of the Stock Option
Plans -- Federal Income Tax Consequences."
    
 
   
     As of April 19, 1996, the Company had 2,319,949 shares of Class A Common
Stock reserved for issuance upon exercise of non-qualified stock options
previously granted under the 1982 Option Plan; no ISOs are outstanding. The 1982
Option Plan terminated on June 10, 1992, and no additional options may be
granted. 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
 
                                       41
<PAGE>   44
 
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.
 
     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 June 10, 1992, and no additional options
may be granted. As of April 19, 1996, there were 3,367 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, directors and consultants. As of April
19, 1996, the Company had 8,016,980 shares of Class A Common Stock reserved for
issuance upon the exercise of options 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. Shares of Class A Common Stock acquired through the exercise of a
stock option must have been owned by the optionee at least six months before
such shares may be used to pay the exercise price of another option. Any income
tax 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
 
                                       42
<PAGE>   45
 
(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 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 April 19,
1996, there were 13,569 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 terminated on July 31, 1995, and no
additional options may be granted.
    
 
1995 STOCK OPTION PLAN
 
   
  General
    
 
   
     The 1995 Stock Option Plan (the "1995 Option Plan") was approved by the
Board of Directors on April 14, 1995 and by the stockholders at the Company's
1995 Annual Meeting of Stockholders. The 1995 Option Plan became effective on
July 14, 1995 and will terminate on, and no option may be granted after, July
31, 1998. The terms of the 1995 Option Plan are substantially similar to those
currently in effect with respect to the 1992 Option Plan, except that pursuant
to the 1995 Option Plan a maximum of 12,000,000 shares of Class A Common Stock
will be authorized for issuance, the aggregate number of shares subject to
options granted to any individual may not exceed 500,000 shares, and ISOs as
well as non-qualified stock options may be granted. As of April 19, 1996, the
Company had 9,015,155 shares of Class A Common Stock reserved for issuance under
the 1995 Option Plan.
    
 
   
  Eligibility and Participation
    
 
   
     The persons eligible to receive options under the 1995 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. The aggregate
number of shares subject to options granted to any individual may not exceed
500,000 shares. Other than the foregoing, the 1995 Option Plan does not provide
any limit as to the number of shares that may be subject to options granted to
any one individual. As of April 19, 1996, there were 5,266 option agreements
with optionees outstanding under the 1995 Option Plan. As of April 19, 1996,
there was one option agreement outstanding representing the grant of an ISO
under the 1995 Option Plan.
    
 
                                       43
<PAGE>   46
 
   
  Amendment and Termination
    
 
   
     The Board of Directors or the Operating Committee of the Board of Directors
may at any time suspend or terminate the 1995 Option Plan and may amend it from
time to time in such respects as the Board of Directors or the Operating
Committee may deem advisable in order that Options granted thereunder shall
conform to any change in the law, or in any other respect which the Board of
Directors or the Operating Committee may deem to be in the best interests of the
Company; provided, however, that no such amendment shall, without the approval
of a majority of the voting power of the capital stock of the Company present or
represented and entitled to vote at a duly constituted meeting of the
stockholders, (i) increase the maximum number of shares for which Options may be
granted under the 1995 Option Plan, except as specified in Paragraph 11 of the
1995 Option Plan, (ii) change the provisions of Paragraph 6(c) of the 1995
Option Plan relating to the establishment of the Exercise Price other than to
change the manner of determining the fair market value of the Company's Common
Stock to conform with any then applicable provisions of the Code or regulations
issued thereunder or (iii) permit the granting of Options to members of the
Stock Option Committee.
    
 
   
GENERAL PROVISIONS OF THE STOCK OPTION PLANS
    
 
   
  General
    
 
   
     All shares issued upon exercise of options granted under the 1982 Option
Plan, the 1992 Option Plan and the 1995 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
outright, 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 April 19, 1996, there were 2,319,949 shares of Class A Common
Stock reserved for issuance under the 1982 Option Plan, 8,016,980 shares of
Class A Common Stock reserved for issuance under the 1992 Option Plan and
9,015,155 shares of Class A Common Stock reserved for issuance under the 1995
Option Plan.
    
 
     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)
 
                                       44

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 and the 1995 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 Stock
Option 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
who 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), (v) with
respect to the 1995 Option Plan, determine whether to grant ISOs or
non-qualified stock options, and (vi) 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), L.A. Kull and J.B. Wiesler. The address of each such person is
Science Applications International Corporation, 10260 Campus Point Drive, San
Diego, CA 92121.
    
 
  Federal Income Tax Consequences
 
   
     The following 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 and 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 following tax consequences apply to any particular
option holder's specific circumstances or will continue to apply in the future.
All outstanding options under the 1982 and 1992 Option Plans are non-qualified
options. Options granted under the 1995 Option Plan may be non-qualified options
or ISOs, as determined by the Committee at the time of grant.
    
 
   
     Non-Qualified Options. Generally, the optionee will not be taxed upon the
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 capital asset
in the holder's
    
 
                                       45
<PAGE>   48
 
   
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 will (i) be taxed as ordinary
     income in an amount equal to the fair market value of the shares at the
     time of exercise, (ii) have a basis equal to the amount included in taxable
     income by the optionee and (iii) have a holding period that begins on the
     date of the exercise.
    
 
   
     Incentive Stock Options. Options granted under the 1995 Option Plan
designated as such are intended to constitute ISOs for federal income tax
purposes. Generally, an optionee receiving an ISO will not be in receipt of
taxable income upon the grant of the ISO or upon its timely exercise. The
exercise of an ISO will be timely if made during its term and if the optionee
remains an employee of the Company at all times during the period beginning on
the date of grant of the ISO and ending on the date three months before the date
of exercise (or one year before the date of exercise in the case of death). Upon
the ultimate sale of the capital stock received upon such exercise, except as
noted below, the optionee will recognize long-term capital gain or loss (if the
capital stock is a capital asset in the hands of the optionee) equal to the
difference between the amount realized upon such sale and the exercise price.
The Company, under these circumstances, will not be entitled to any federal
income tax deduction in connection with either the exercise of the ISO or the
sale of such shares by the optionee.
    
 
     However, if the capital stock acquired upon the timely exercise of an ISO
is disposed of by the optionee prior to the expiration of two years from the
date of grant of the ISO or within one year from the date such capital stock is
transferred to the optionee upon exercise (a "disqualifying disposition"), any
gain realized by the optionee generally will be taxable at the time of such
disqualifying disposition as follows: (i) at ordinary income tax rates to the
extent of the difference between the exercise price and the lesser of the fair
market value of the capital stock on the date the ISO is exercised or the amount
realized on such disqualifying disposition and (ii) if the capital stock is a
capital asset in the hands of the optionee, as short-term or long-term capital
gain to the extent of any excess of the amount realized on such disqualifying
disposition over the fair market value of the capital stock on the date which
governs the determination of his or her ordinary income. If a disqualifying
disposition is made in a transaction in which a loss would not be recognized
under the Code (e.g., a gift, sale to certain related parties, sale followed by
a purchase of stock or grant of a new option under the "wash sale" rules), the
taxable gain recognized as a result of such disqualifying disposition will not
be limited to the amount of gain realized in the disqualifying disposition. In
the case of a disqualifying disposition, the Company may claim a federal tax
deduction at the time and in the amount taxable to the optionee as ordinary
income. Any capital gain realized by the optionee will be long-term capital gain
if the optionee's holding period for the capital stock at the time of
disposition is more than one year; otherwise, it will be short-term capital
gain.
 
     Net capital gains are currently 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 phase-out of personal exemptions may
result in effective marginal tax rates higher than 28% for net capital gains and
39.6% for ordinary income.
 
   
     To the extent that the aggregate fair market value (based on the fair
market value on the date of grant, which is the exercise price of the ISO) of
shares with respect to which an ISO first becomes exercisable (i.e., vests)
within any calendar year exceeds $100,000, the portion of the ISO representing
such excess is treated as
    
 
                                       46
<PAGE>   49
 
   
a non-qualified stock option, subject to the tax treatment described above. See
"Employee Benefit Plans -- General Provisions of the Stock Option
Plans -- Federal Income Tax Consequences -- Non-Qualified Options."
    
 
   
          Alternative Minimum Tax. For purposes of the alternative minimum tax
     provisions contained in Section 55 of the Code, the exercise of an ISO will
     be treated as though it were a non-qualified option under Section 83 of the
     Code, but solely for purposes of determining the optionee's alternative
     minimum taxable income. The minimum tax is imposed at a rate of 26% of
     alternative minimum taxable income (taxable income increased by items of
     tax preference and adjusted for certain other items) up to $175,000 (and
     28% of any additional such income) over a specified exemption amount
     ($45,000 for married taxpayers filing jointly, $33,750 for single
     taxpayers, but phased out at specified levels of income), but is payable
     only if the minimum tax exceeds the taxpayer's regular tax liability for
     the year.
    
 
   
          Exercise with Shares of Capital Stock. If payment for the exercise
     price of an ISO is made by surrendering previously owned shares of the
     capital stock, the following rules will apply:
    
 
          If shares of "statutory option stock" (i.e., stock previously acquired
     pursuant to the exercise of an ISO) are surrendered in payment of the
     exercise price of an ISO and if, at the date of surrender, the applicable
     holding period for such shares has not been met (e.g., if shares previously
     acquired upon the exercise of an ISO are surrendered within two years from
     the date of grant or within one year from the date the shares were
     transferred to the optionee), such surrender will constitute a
     "disqualifying disposition" and any gain realized on such transfer will
     thus be taxable according to the rules described above for disqualifying
     dispositions. If the shares surrendered are not statutory option stock, or
     if they are statutory option stock but have been held for the requisite
     holding period, no gain or loss should be recognized upon such surrender.
     Although the Internal Revenue Service will not issue any rulings as to the
     effect of such an exercise, it has issued a published ruling stating that
     no gain or loss will be recognized upon the surrender of shares upon
     exercise of a non-qualified stock option, and the Treasury Department has
     issued proposed regulations which, if adopted in their current form, would
     appear to provide that, except as discussed above, in general, when shares
     are surrendered upon exercise of an ISO:
 
          (a) No gain or loss will be recognized as a result of the exchange.
 
   
          (b) A number of shares received which is equal in number to the shares
     surrendered will have a basis equal to the shares surrendered and (except
     for purposes of determining whether a disposition will be a disqualifying
     disposition) will have a holding period which includes the holding period
     of the shares exchanged.
    
 
          (c) Any additional shares received will have a zero basis and will
     have a holding period which begins on the date of the exchange. If any of
     the shares received are disposed of within two years of the date of grant
     of the ISO or within one year after the date shares were transferred to the
     optionee, the shares with the lowest basis (i.e., a zero basis) will be
     deemed to be disposed of first and such disposition will be a disqualifying
     disposition giving rise to ordinary income as discussed above.

                          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 April 19, 1996, there were 47,627,245
shares of Class A Common Stock, 329,673 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 21
directors, evenly divided between Class I, 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 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.

<PAGE>   52
 
   
     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 5% 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 5% 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, CA 92121, Attention: Corporate
Secretary.
    
 
     The amendment of certain provisions of the Certificate of Incorporation and
Bylaws require the approval of not less than two-thirds of the total voting
power of all outstanding shares of voting stock of the Company. Such provisions
relate to the number of directors, the election of directors and the vote of
stockholders required to modify the provisions of the Certificate of
Incorporation and Bylaws requiring such approvals.
 
     The Company acts as its own transfer agent for the Class A Common Stock and
Class B Common Stock.
 
   
     As of April 19, 1996, there were 12,630 record holders of Class A Common
Stock and 130 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 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 ISOs, (iii)
in exchange for shares of
    
 
                                       50
<PAGE>   53
 
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 Employee
Stock Ownership Plan 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 Common Stock
without the prior written approval of the Company. 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, director or a consultant of the Company or by a person who
acquired such shares other than by purchase, directly or indirectly, from an
employee, director or consultant of 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
 
                                       51
<PAGE>   54
 
   
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. See "Risk Factors -- Restrictions on Class A Common Stock."
    
 
  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, 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 dividend, 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
dividend, 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.
    
 
     Holders of shares of Preferred Stock will have no preferential or
preemptive 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.
 
ANTI-TAKEOVER EFFECTS
 
     The combined effect of the classification of the Board of Directors into
three different classes, the cumulative voting rights of the stockholders, the
Supermajority Vote Requirements, the provisions of the Certificate of
Incorporation and Bylaws of the Company requiring the approval of at least
two-thirds of the voting power of all outstanding shares of Common Stock for
certain amendments to the Certificate of Incorporation or Bylaws, the Company's
right of first refusal, and the Company's right of repurchase upon termination
of employment or affiliation, may discourage, delay or prevent attempts to
acquire control of the
 
                                       52
<PAGE>   55
 
   
Company that are not approved by the Company's Board of Directors. The
provisions may, individually or collectively, have the effect of discouraging
takeover attempts that some stockholders might deem to be in their best
interests, including tender offers in which stockholders might receive a premium
for their shares over the Formula Price available in the Limited Market, as well
as making it more difficult for individual stockholders or a group of
stockholders to elect directors. However, the Board of Directors believes that
these provisions are in the best interests of the Company and its stockholders,
because such provisions may encourage potential acquirors to negotiate directly
with the Board of Directors which is in the best position to act on behalf of
all stockholders. See "Risk Factors -- Anti-Takeover Effects."
    
 
                                 LEGAL OPINION

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, excluding information contained in
        periodic reports filed with or furnished to the Commission by the
        Registrant pursuant to Section 13 or Section 15(d) of the Securities
        Exchange Act of 1934 that are incorporated by reference 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
 
                                      II-3
<PAGE>   60
 
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:

Science Applications
International Corporation
10260 Campus Point Drive
San Diego, CA 92121
 
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 29,823,500 shares of its Class A Common
Stock, par value $0.01 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 (all 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 176,500 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 May 6, 1996 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.
 
     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
                                      Corporate Vice President
                                      and General Counsel
