ITEM 1.  BUSINESS.
 
                                  THE COMPANY
 
     Science Applications International Corporation (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 ("DOD"),
Department of Energy ("DOE"), Department of Transportation, Department of
Veterans Affairs ("VA"), Environmental Protection Agency and National
Aeronautics and Space Administration ("NASA"). Revenues generated from the sale
of Technical Services and Products to the U.S. Government as a prime contractor
or subcontractor accounted for approximately 79%, 83% and 86% of revenues in
fiscal years 1997, 1996 and 1995, 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. The
percentage of revenues attributable to Technical Services has increased since
fiscal year 1995 while Product revenues have correspondingly decreased.
Technical Services revenues and Product revenues were 94% and 6%, respectively,
for fiscal year 1997; 93% and 7%, respectively, for fiscal year 1996; and 91%
and 9%, respectively, for fiscal year 1995. On March 7, 1997, the Company sold
its Science Applications International Technologies ("SAIT") business unit,
which designed, manufactured and sold certain ruggedized computers and display
products and accounted for 49% of the Company's Product revenues in fiscal year
1997. The Company provides Technical Services primarily in the areas of
"National Security," "Health," "Environment," "Energy" and "Other Technical
Services," the last of which includes the Company's transportation, commercial
information technology and space business areas. The percentage of Technical
Services revenues attributable to National Security-related work has gradually
declined to 44% of total revenues for fiscal year 1997. For fiscal year 1997,
the Health, Environment, Energy and Other Technical Services business areas
accounted for 14%, 11%, 5% and 20%, respectively, of total revenues. For certain

PRODUCTS
 
     The Company designs, develops and manufactures high-technology products for
government and commercial customers. Examples of the Company's Products include
the following:
 
     - Automatic equipment identification technology for rail, truck, air and
       sea transportation modes.
 
     - Digital and analog recording products, signal reconnaissance data
       processors and telecommunications products for the intelligence
       community.
 
                                   RESOURCES
 
     The Technical Services and Products provided by the Company utilize a wide
variety of resources. The Company anticipates the continued availability of the
resources required for the Technical Services and Products provided to
customers. A substantial portion of the computers and other equipment, materials
and subcontracted work required by the Company could be procured from alternate
supply sources. However, with respect to certain products and programs, the
Company depends on a particular source or vendor. While a temporary or permanent
disruption in the supply of these materials or services could cause
inconvenience or delay or impact the profitability of the affected programs or
products, the Company believes it would not materially affect the profitability
or operations of the Company as a whole.
 
     The availability of skilled employees who have the necessary education
and/or experience in specialized scientific and technological disciplines
remains critical to the future growth and profitability of the Company. Because
of the Company's growth and the competitive business environment, it has become
more difficult to meet all of the Company's needs for such employees in a timely
manner. However, to date, such difficulties have not had a significant impact on
the Company. The Company intends to continue to devote significant resources to
recruit and retain qualified employees. Further, as an inducement, the Company
maintains a
 
                                        4
<PAGE>   6
 
variety of benefit programs for its employees, including retirement and bonus
plans, group life, health, accident and disability insurance and offers its
employees the opportunity to participate in the Company's employee ownership
program. See "Employees And Consultants" and "The Limited Market."
 
                                   MARKETING
 
     The Company's marketing activities are primarily conducted by its own
professional staff of engineers, scientists, analysts and other personnel. The
Company's marketing approach for its Technical Services begins with the
development of information concerning the requirements of the U.S. Government
and other potential customers for the types of Technical Services provided by
the Company. Such information is gathered in the course of contract performance
and from formal briefings, participation in professional organizations and
published literature. This information is then evaluated and exchanged among
marketing groups within the Company (organized along functional, geographic and
other lines) in order to devise and implement, subject to management review and
approval, the best means of taking advantage of available business
opportunities, including the preparation of proposals responsive to the stated
and perceived needs of customers.
 
     The Company's Products are marketed primarily through the Company's own
sales force, which is augmented by independent sales representatives.
 
                                  COMPETITION
 
     The businesses in which the Company is engaged are highly competitive. The
Company has a large number of competitors, some of which have been established
longer and have substantially greater financial resources and larger technical
staffs than the Company. Some of the other competitors, although smaller in
size, are more highly specialized. In addition, the U.S. Government's own
in-house capabilities and federal non-profit contract research centers are also
competitors of the Company because they perform certain types of services which
might otherwise be performed by the Company.
 
     The primary competitive factors in the business areas in which the Company
is engaged are technical, management and marketing competence and price. The
Company's continued success is dependent upon its ability to hire and retain
highly qualified scientists, engineers, technicians, management and professional
personnel who will provide superior service and performance on a cost-effective
basis.
 
                             SIGNIFICANT CUSTOMERS
 
     During the fiscal years ended January 31, 1997, 1996 and 1995,
approximately 80%, 84% and 88%, respectively, of the Company's contract revenues
from the Technical Services segment and approximately 57%, 71% and 68%,
respectively, of the Company's contract revenues from the Products segment, were
attributable to prime contracts with the U.S. Government or to subcontracts with
other contractors engaged in work for the U.S. Government.
 
     In fiscal years 1997, 1996 and 1995, the U.S. Air Force accounted for
approximately 8%, 9% and 11%, respectively, of consolidated revenues, the U.S.
Army accounted for approximately 16%, 22% and 19%, respectively, of consolidated
revenues, the U.S. Navy accounted for approximately 10%, 9% and 10%,
respectively, of consolidated revenues and the DOE accounted for approximately
7%, 10% and 11%, respectively, of consolidated revenues.
 
     During fiscal year 1996, approximately 10% of the Company's consolidated
revenues were derived from one U.S. Government contract to automate the
information systems for the DOD's medical treatment facilities worldwide. This
contract was substantially completed in 1997. No other single contract in the
Technical Services segment accounted for 10% or more of consolidated revenues in
fiscal year 1996 and no single contract in the Technical Services segment
accounted for 10% or more of consolidated revenues in fiscal years 1997 or 1995.
 
                                        5
<PAGE>   7
 
     No single customer or contract in the Products segment accounted for 10% or
more of consolidated revenues in fiscal years 1997, 1996 or 1995.
 
                              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 terminations of U.S. Government programs or contracts will not have a
material adverse effect on the Company in the future.
 
     The Company's business with the U.S. Government and other customers is
generally performed under cost-reimbursement, time-and-materials, fixed-price
level-of-effort or firm fixed-price contracts. Under cost-reimbursement
contracts, the customers reimburse 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 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.
 
     During the fiscal years ended January 31, 1997, 1996 and 1995,
approximately 57%, 57% and 63%, respectively, of the Technical Services revenues
were derived from cost-reimbursement type contracts and approximately 20%, 16%
and 13%, 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 the
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 and Product
revenues, exclusive of related fees, at January 31, 1997 were $13,009,000 and
$967,000, respectively. The Company expects to recover substantially all such
costs; however, no assurance can be given that the contracts or contract
amendments will be received or that the related costs will be recovered.
 
     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, 1995. 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.

                      PATENTS AND PROPRIETARY INFORMATION
 
     Although the Company owns or has made application for patents on certain
products and processes, the nature of the Technical Services and Products
provided by the Company is such that the Company does not presently consider its
competitive position to be dependent upon patent protection. The Company claims
a proprietary interest in certain of its products, software programs,
methodology and know-how. Such proprietary information is protected by
copyrights, trade secrets, licenses, contracts and other means.
 
     The U.S. Government has certain rights to data, computer codes and related
material developed by the Company under U.S. Government-funded contracts and
subcontracts. Generally, the U.S. Government may disclose such information to
third parties, including, in some instances, competitors. In the case of
subcontracts, the prime contractor may also have certain rights to the programs
and products developed by the Company under the subcontract.
 
                                    BACKLOG
 
     Backlog includes only the funded dollar amount of contracts in process and
does not include the dollar amount of projects for which the Company has been
given permission by the customer (i) to begin work but for which a formal
contract has not yet been entered into or (ii) to extend work under an existing
contract prior to the formal amendment or modification of the existing contract.
In these cases, either contract negotiations have not been completed or a
contract or contract amendment has not been executed. When a contract or
contract amendment is executed, the backlog will be increased by the difference
between the dollar value of the contract or contract amendment and the revenue
recognized to date.
 
     The backlog for the Technical Services segment at January 31, 1997 and 1996
amounted to approximately $1,120,000,000 and $971,000,000, respectively, and the
backlog for the Products segment at those dates amounted to approximately
$74,000,000 and $109,000,000, respectively. At January 31, 1997, approximately
$24,000,000 of the backlog for the Products segment was related to the SAIT
business unit, which was sold on March 7, 1997. The Company expects that a
substantial portion of its backlog at January 31, 1997 (other than the amounts
related to SAIT) will be recognized as revenues prior to January 31, 1998. Some
contracts associated with the backlog are incrementally funded and may continue
for more than one year.
 
                           EMPLOYEES AND CONSULTANTS
 
     As of March 14, 1997, the Company employed approximately 22,600, including
approximately 2,000 persons on a part-time basis. The Company also utilizes the
services of consultants to provide specialized technical and other services on
specific projects.
 
     The highly technical and complex services and products provided by the
Company are dependent upon the availability of professional, administrative and
technical personnel having high levels of training and skills. Because of the
Company's growth and competitive business environment, it has become more
difficult to meet all of the Company's needs for such employees in a timely
manner. However, to date, such difficulties have not had a significant impact on
the Company. The Company intends to continue to devote significant resources to
recruit and retain qualified employees. Management believes the Company's
orientation towards employee ownership is a major factor in the Company's
ability to attract and retain qualified personnel.
 
     None of the Company's employees are represented by a labor union. To date,
no strikes or work stoppages have been experienced and the Company considers its
relations with its employees to be good.
 
ITEM 2.  PROPERTIES.
 
     As of March 14, 1997, the Company conducted its operations in more than 330
offices and laboratory facilities located in 43 states, the District of Columbia
and various foreign countries and occupied a total of approximately 5,200,000
square feet of space. The Company has principal locations in the San Diego,
California and the Washington, D.C. metropolitan areas and occupies over
1,000,000 square feet of space in each of these locations. The information set
forth below is accurate as of March 14, 1997.

     The Company owns and occupies six buildings totaling approximately 550,000
square feet of space situated on 22.2 acres of land owned by the Company in the
Golden Triangle area of San Diego, California and leases a 128,500 square foot
office building located on that land. The Company has an option to purchase this
leased facility.
 
     At the principal location of the Company in the Washington, D.C.
metropolitan area (McLean, Virginia), the Company owns and occupies a 287,000
square foot building located on 10 acres of land and leases two buildings
containing a total of approximately 425,000 square feet of space. The Company
has certain rights to purchase these leased buildings. In addition, the Company
owns and occupies a 62,000 square foot building on 2.6 acres of land in Reston,
Virginia.
 
     The Company also owns and occupies (a) a 62,500 square foot building on
approximately 12 acres of land in Virginia Beach, Virginia, (b) an 83,000 square
foot building on approximately 8.4 acres of land in Oak Ridge, Tennessee, (c)
two buildings totaling 79,400 square feet on 4.5 acres in Dayton, Ohio, (d) a
101,500 square foot building on 18 acres in Huntsville, Alabama, (e) a 95,500
square foot building on approximately 7.3 acres of land in Columbia, Maryland

in Richland, Washington. The Company also leases a 30,000 square foot office
building in Orlando, Florida. The Company has an option to purchase this
building.
 
     The nature of the Company's business is such that there is no practicable
way to relate occupied space to industry segments. The Company considers its
facilities suitable and adequate for its present needs. See Note K of Notes to
Consolidated Financial Statements of the Company on page F-19 of this Form 10-K
for information regarding commitments under leases.
 
ITEM 3.  LEGAL PROCEEDINGS.
 
     The Company is involved in various investigations, claims and lawsuits

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.
 
                               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 fair market value of the Class A Common Stock
determined pursuant to the formula and valuation process described below (the
"Formula Price") to employees, consultants and directors of the Company who have
been approved by the Board of Directors or the Operating Committee of the Board
of Directors as being entitled to subscribe 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 ("ESOP"), Cash or Deferred Arrangement ("CODA"),
1995 Employee Stock Purchase Plan, Stock Compensation Plan, Management Stock
Compensation Plan, Key Executive Stock Deferral Plan and the Syntonic
Technology, Inc. Retirement Savings Plan ("Syntonic Savings Plan")
(collectively, the "Benefit Plans") 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, ESOP, CODA and the Syntonic Savings
Plan) 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 shares in excess of
500 shares of Class A Common Stock will be accepted on a pro-rata basis
determined by dividing the total number of shares remaining under purchase
orders by the total number of shares remaining under sell orders. If, however,
there are insufficient purchase orders to support the primary allocation of 500
shares of Class A Common Stock for each proposed seller, then the purchase
orders will be allocated equally among all of the proposed sellers up to the
total number of shares offered for sale.
 
     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 1997 and 1996, the Company purchased 117,163 shares
and 33,372 shares, respectively, in the Limited Market. The Company's purchases
in fiscal years 1997 and 1996 accounted for 6.2% and 2.2%, respectively, of the
total shares purchased by all buyers in the Limited Market during such years.
 
     During the 1997 and 1996 fiscal years, the trustees of the Company's CODA,
1993 Employee Stock Purchase Plan, 1995 Employee Stock Purchase Plan and the
Syntonic Savings Plan purchased an aggregate of 1,148,829 shares and 1,045,711
shares, respectively, in the Limited Market. These purchases accounted for
approximately 60.9% and 67.2% of the total shares purchased by all buyers in the
Limited Market during fiscal years 1997 and 1996, 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 Benefit Plans decrease and purchases by the Company do not increase, the
ability of stockholders to resell their shares in the Limited
 
                                       10
<PAGE>   12
 
   
Market will likely be adversely affected. Although all shares of Class A Common
Stock offered for sale were sold in the Limited Market on each Trade Date
occurring during the last two fiscal years, 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.
    
 
   
     To the extent that the aggregate number of shares sought to be purchased by
authorized buyers exceeds the aggregate number of shares offered for sale by
stockholders, the Company may, but is not obligated to, sell authorized but
unissued shares of Class A Common Stock in the Limited Market. In fiscal years
1997 and 1996, the Company sold an aggregate of 85,505 and 246,831 authorized
but unissued shares of Class A Common Stock, respectively, in the Limited
Market. The Company's sales in fiscal years 1997 and 1996 accounted for 4.5% and
15.9%, respectively, of the total shares sold by all sellers in the Limited
Market during such years. To the extent that the Company chooses not to sell
authorized but unissued shares of Class A Common Stock in the Limited Market,
the ability of individuals to purchase shares on the Limited Market may be
adversely affected. No assurance can be given that an individual desiring to buy
shares of the Company's Class A Common Stock in any future trade will be able to
do so.
    
 
PRICE RANGE OF CLASS A COMMON STOCK AND CLASS B COMMON STOCK
 
   
     The fair market value of the Class A Common Stock is established by the
Board of Directors pursuant to the valuation process described below, which uses
the formula set forth below 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 Company's Certificate of Incorporation, the
price applicable to shares of Class B Common Stock is equal to five times the
Formula Price.
    
 
   
     The following formula ("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 to cause the price generated by the Formula to equal the
fair market value of the Class A Common Stock as determined by the Board of
Directors following an amendment of the Formula. The 5.66 multiplier has not
been assessed for change since that time. The Market Factor is a numerical
factor which is reviewed and set by the Board of Directors as part of the
valuation process. Historical values for each variable contained in the Formula
are set forth in the table on page 12.
    
 
   
     In determining a fair market value for the Class A Common Stock, the Board
of Directors considers the performance of the general securities markets and
relevant industry groups, the historical financial performance of the Company
versus comparable public companies, the prospects for the Company's future
performance, general economic conditions, input from an independent appraisal
firm and other relevant factors. The Board of Directors sets the Market Factor
at the value which causes the Formula to yield a price equal to a fair market
value for the Class A Common Stock as determined by the Board. In conjunction
with the Board of Directors' valuation process, an appraisal of Class A Common
Stock is prepared by an independent appraisal firm for the Committee and is
relied upon by the Committee and the Board of Directors. The Formula Price and
Market Factor, as determined by the Board of Directors, remains in effect until
subsequently changed by the Board of Directors. The price of the Class A Common
Stock and the Market Factor could be subject to greater fluctuations in the
future than in the past due to the Company's plans to increase (i) the
proportion of the Company's business involving private sector customers,

tional customers and information technology, (ii) the financial leverage impact
of increased debt levels of the Company if debt financing is used to finance the
Bellcore acquisition or for other purposes and (iii) other equity transactions
that the Company may pursue. See "Risk Factors -- Possible Volatility of Stock
Price."
    
 
     The Formula Price of the Class A Common Stock, expressed as an equation, is
as follows:

     The Board of Directors has broad discretion to modify or even delete the
Formula in its entirety. Nevertheless, 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, 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. 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.
See "Risk Factors -- Offering Price Determined by Formula."
    
 
   
     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
each of the variables contained in the Formula, including 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 results in a fair market value for the Class A Common Stock
within a broad range of financial criteria.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.
 
RESULTS OF OPERATIONS
 
     Revenues increased 11%, 12% and 15% in 1997, 1996 and 1995, respectively,
over the prior year. Revenues in 1997 from the Company's principal customer, the
U.S. Government, continued to shift toward lower cost service type contracts.
This trend reflects the increasingly competitive business environment in the
Company's traditional business areas, as well as the Company's increased success
in the engineering and field services markets, which typically involve lower
cost contracts.
 
     The Company provides diversified professional and technical services
("Technical Services") and designs, develops and manufactures high-technology
products ("Products"). The sale of Technical Services and Products to the U.S.
Government as a prime contractor or subcontractor accounted for 79% of revenues
in 1997, 83% in 1996 and 86% in 1995. This relative decrease is attributable to
growth in non-U.S. Government revenues as a result of the Company's efforts to
increase revenues from commercial and international clients and state and local
governments in the health, information technology and transportation business
areas. On an absolute basis, U.S. Government revenues increased 6% in 1997, 9%
in 1996 and 12% in 1995. Non-U.S. Government revenues increased 40% in 1997 and
34% in 1996 and 1995, over the prior year.
 
     The following table summarizes revenues by contract type for the last three
years:

</TABLE>
 
     Cost-reimbursement contracts provide for the reimbursement of direct costs
and allowable indirect costs, plus a fee or profit component. Time-and-materials
("T&M") contracts typically provide for the payment of negotiated fixed hourly
rates for labor hours incurred plus reimbursement of other allowable direct
costs at actual cost plus allocable indirect costs. Fixed-price level-of-effort
("FP-LOE") contracts are similar to T&M contracts since ultimately revenues are
based upon the labor hours provided to the customer. Firm fixed-price contracts
require the Company to provide stipulated products, systems or services for a
fixed price. The Company assumes greater performance risk on firm fixed-price
contracts and the failure to accurately estimate ultimate costs or to control
costs during performance of the work may result in reduced profits or losses.
The relative increase in revenues from firm fixed-price contracts and associated
relative decrease in revenues from cost-reimbursement contracts from 1995 to
1997 result primarily from the Company's growth in non-U.S. Government revenues.
The Company's non-U.S. Government customers typically do not contract on a cost-
reimbursement basis.
 
     The Company's business is directly related to the receipt of contract
awards and contract performance. There were 412 contracts with annual revenues
greater than $1 million in 1997, compared with 349 and 333 such contracts in
1996 and 1995, respectively. These larger contracts represented 75% of the
Company's revenues in 1997 compared to 76% in 1996 and 1995. Of these contracts,
28 contracts had individual revenues greater than $10 million in 1997 compared
to 21 such contracts in 1996 and 20 in 1995. The remainder of the Company's
revenues are derived from a large number of contracts with individual revenues
less than $1 million. Although the Company has committed substantial resources
and personnel required to pursue and perform larger contracts, the Company
believes it also maintains a suitable environment for the performance of
smaller, highly technical research and development contracts. These smaller
programs often provide the foundation for the Company's success on larger
procurements. Revenues on the Company's contracts are generated from the efforts
of its technical staff as well as the pass through of costs for material and
subcontract efforts, which primarily occur on large, multi-year contracts. At
the end of 1997, the Company had 20,900 full-time employees compared to 19,500
and 16,700 at the end of 1996 and 1995, respectively. Material and subcontract
("M&S") revenues were $667 million in 1997, $616 million in 1996 and $560
million in 1995. As
 
                                       14
<PAGE>   16
 
a percentage of total revenues, M&S revenues have remained relatively constant
at 28% in 1997 and 29% in 1996 and 1995.
 
     The revenue mix between the Technical Services segment and the Products
segment was 94% and 6%, respectively, of consolidated revenues in 1997, 93% and
7%, respectively, in 1996 and 91% and 9%, respectively, in 1995. Within the
Technical Services segment, revenues are further classified between "National
Security," "Health," "Environment," "Energy" and "Other Technical Services."
Other Technical Services includes the transportation, commercial information
technology, space and other business areas.
 
     National Security revenues were 44% of total revenues in 1997 compared to
45% in 1996 and 46% in 1995. Although National Security revenues declined as a
percentage of total revenues, on an absolute basis, these revenues increased 8%
in 1997 and 1996 and 7% in 1995 over the prior year, in spite of declines in the
overall defense market during these periods. The U.S. Government maintained
funding in areas in which the Company has strong capabilities, such as research
and development, training, simulation and test and evaluation. Revenues in the
Health business area were 14% of total revenues in 1997 and 1996 and 11% in
1995. While Health revenues as a percentage of total revenues have remained
constant in 1997 and 1996, the Health contract which generated approximately 10%
of total revenues in 1996 was substantially completed in 1997. However, to date,
the Company has been successful maintaining the level of its revenues in the
Health business area through other contracts. Revenues from the Environment
business area were 11% of total revenues in 1997, 13% in 1996 and 14% in 1995.
Energy revenues were 5% of total revenues in 1997, 7% in 1996 and 9% in 1995.
The decreases in the Environment and Energy business areas primarily reflect the
budget reductions and changing priorities of the Company's U.S. Government and
commercial customers. Other Technical Services revenues were 20% of total
revenues in 1997, 14% in 1996 and 11% in 1995. The continued growth in Other
Technical Services reflects the Company's expansion in the transportation and
commercial information technology markets and mirrors the country's shift of
priorities and resources from defense programs to civilian programs in areas
such as transportation. The Company expects this trend to continue. In order for
the Company to maintain or exceed historical revenue growth rates, it will need
to continue to increase its market share in the National Security business area
and/or increase its revenues from the health, environment, energy, space,
transportation and commercial information technology business areas.
 
     Products revenues were 6% of total revenues in 1997, 7% in 1996 and 9% in
1995. Products revenues are largely determined by the stage of contract
performance and the purchasing needs and capabilities of the Company's customers
and thus, can fluctuate from year to year. Subsequent to the 1997 fiscal year
end, on March 7, 1997, the Company sold the majority of the net assets of the
SAIT business unit, which accounted for 49% of the Company's Product revenues in
1997. The purchase price is subject to potential adjustments, plus contingent
payments if certain milestones are achieved by the business post-closing. Under
the agreement, the Company also retains certain contingent liabilities. Given
the early stage of the settlement period, the impact of the sale on the
consolidated financial position and results of operations has not been
determined. The Company, however, does not anticipate a loss on the sale.
 
     The cost of revenues as a percentage of revenues (excluding interest
income) was 87.2% in 1997, 87.0% in 1996 and 88.2% in 1995. The decreased cost
of revenues percentage in 1997 and 1996 represents the combination of a number
of offsetting effects. The primary trend which increased the cost of revenues
percentage is faster revenue growth in lower cost service type contracts, which
typically have more of their associated costs in cost of revenues and less costs
in selling, general and administrative ("SG&A") expenses. Trends which decreased
the cost of revenues percentage are the growth in commercial revenues, which
have more of their associated costs in SG&A as opposed to cost of revenues and
decreased overruns from better performance on certain firm fixed-price contracts
in 1997 and 1996 compared to 1995.
 
     SG&A expenses as a percentage of revenues (excluding interest income) were
8.0%, 8.1% and 7.6% in 1997, 1996 and 1995, respectively. SG&A is comprised of
general and administrative ("G&A"), bid and proposal ("B&P") and independent
research and development ("IR&D") expenses. While the level of B&P activity and
costs has historically fluctuated depending on the availability of bidding
opportunities and resources, B&P costs have remained constant in relation to
revenues over the past three years. IR&D costs also remained relatively constant
in relation to revenues over the past three years. G&A expenses as a
 
                                       15
<PAGE>   17
 
   
percentage of total revenues were 5.6% in 1997 compared to 5.8% in 1996 and 5.2%
in 1995. The higher level of G&A expenses in 1997 and 1996 was primarily
attributable to the increased charges taken to income for the amortization and
impairment of goodwill. Continued declining operating results of certain
acquired companies made the recovery of certain goodwill unlikely as determined
by the undiscounted cash flow method. The Company reduced goodwill by $6.2
million to its estimated recoverable value. The Company continues to closely
monitor G&A expenses as part of an on-going program to control indirect costs.
    
 
     Operating profit margins by segment are strongly correlated to the
Company's financial performance on the contracts within each segment. The
operating profit margin in the Technical Services segment was 4.9% in 1997 and
1996 and 4.3% in 1995. The National Security operating profit margin was 4.9% in
1997 and 1996 and 2.8% in 1995. The lower operating profit margin in 1995 as
compared to 1997 and 1996 was a result of overruns on certain firm fixed-price
contracts in the National Security area. Health operating profit margin was 7.4%
in 1997, 6.2% in 1996 and 8.8% in 1995. Environment operating profit margin was
1.9% in 1997, 4.4% in 1996 and 4.9% in 1995. The lower operating profit margin
in 1997 was the result of losses on certain contracts in the local government
and private sector markets. Energy operating profit margin was 5.4% in 1997,
5.1% in 1996 and 5.8% in 1995. The operating profit margin in Other Technical
Services was 4.6% in 1997, 4.3% in 1996 and 3.8% in 1995. The operating profit
margin in the Products segment was 4.6% in 1997, 4.4% in 1996 and 3.9% in 1995.
The lower operating profit margin in 1995 was attributable to overruns on
certain firm fixed-price contracts. In general, overall operating profit margins
for the Company remained constant in 1997 compared to 1996 and improved over
1995 due to better contract financial performance.
 
     Interest expense in 1997, 1996 and 1995 primarily relates to interest on
building mortgages, deferred compensation, notes payable and borrowings
outstanding under the Company's revolving credit loan agreements. Increase in
interest expense was primarily driven by a note assumed in a business
acquisition and interest accrued on the deferred compensation plans. The
increase was offset slightly by lower average outstanding balances under the
Company's revolving credit loan agreements in 1997.
 
     The provision for income taxes as a percentage of income before income
taxes was 43.75% in 1997, 44.0% in 1996 and 38.5% in 1995. The lower effective
tax rate in 1995 compared to 1996 and 1997 was primarily related to a final
settlement of certain issues in 1995 related to the Company's 1986 and 1987
federal and state income tax returns.
 
     On November 20, 1996, the Company entered into a definitive acquisition
agreement to purchase Bell Communications Research, Inc. ("Bellcore"), a
provider of telecommunications services, information networking software and
consulting services. As of December 31, 1996, Bellcore had approximately 5,500
employees and annual revenues of approximately $1 billion. The consummation of
the acquisition is subject to certain conditions and contingencies, including
regulatory approvals which are expected to take between nine and fourteen months
to obtain from the date of the agreement. The Company has no assurance that the
acquisition will be completed. The acquisition, if completed, would result in a
substantial growth in both the employee base and commercial revenues of the
Company. The Company intends to finance a substantial portion of the purchase
price of Bellcore with debt financing. In anticipation of consummating the
transaction, as part of the debt financing, the Company entered into two forward
treasury lock agreements, totaling $200 million, which are intended to hedge
against interest rate fluctuations. The growth and additional debt of this
potential acquisition may place a significant strain on the Company's
management, operational and financial resources. There can be no assurance that
the Company will be able to effectively manage the expansion of its operations
or that the Company's systems, procedures or controls will be adequate to
support the integration of the acquired business. Any inability to effectively
integrate the acquired business or manage the growth could have a material
adverse effect on the Company's results of operations and financial condition.
 
     On January 2, 1997, the Company formed a foreign joint venture,
Informatica, Negocio y Tecnologia, S.A. ("INTESA"), with Venezuela's national
oil company, Petroleos de Venezuela, S.A., to provide information technology
services in Latin America. INTESA's fiscal year end is December 31; therefore,
the Company will begin to consolidate its 60% majority interest in INTESA in the
consolidated financial statements for the year ending January 31, 1998. Since
Venezuela is considered a highly inflationary economy,
 
                                       16
<PAGE>   18
 
the functional currency of INTESA is the U.S. dollar. Re-measurement gains or
losses of this joint venture will be recognized in the consolidated results of
operations.
 
     As described in the Notes to Consolidated Financial Statements, during
1997, the Company adopted Statement of Financial Accounting Standards ("SFAS")
123, "Accounting for Stock-based Compensation." In accordance with the
provisions of SFAS No. 123, the Company applies Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations in accounting for its plans and does not recognize compensation
expense for its employee stock-based compensation plans. The Company has
provided pro-forma disclosures of net income and earnings per share as if the
fair value-based method prescribed by SFAS No. 123 had been applied in measuring
compensation expense.
 
     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings per Share," which establishes standards for computing and
presenting earnings per share ("EPS"). SFAS No. 128 will be adopted by the
Company as required for the interim period and fiscal year ending January 31,
1998. Upon adoption of SFAS No. 128, the Company will present basic EPS as well
as diluted EPS in the period of adoption and restate all prior-period data
presented for comparative purposes. Basic EPS will be computed by dividing
income available to common stockholders by the weighted average number of shares
of common stock outstanding. Diluted EPS will be computed similar to basic EPS
except that the weighted average number of shares of common stock outstanding
will be increased to include the number of additional common shares that would
have been outstanding if the dilutive potential common shares had been issued.
 
     The Company is involved in various investigations, claims and lawsuits
arising in the normal conduct of its business, none of which, in the opinion of
the Company's management, will have a material adverse effect on its
consolidated financial position, results of operations, cash flows or its
ability to conduct business.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's primary sources of liquidity continue to be funds provided by
operations and revolving credit loan agreements. At January 31, 1997 and 1996,
there were no borrowings outstanding under such agreements and cash and cash
equivalents and long-term investments totaled $45 million and $30 million,
respectively. Cash flows generated from operating activities were $90 million in
1997 compared to $46 million in 1996 and $114 million in 1995. Average
receivable days outstanding remained constant at 65 in 1997 and 1996, up from 63
in 1995. The Company continues to actively monitor receivables with emphasis
placed on collection activities and the negotiation of more favorable payment
terms.
 
     Cash flows spent on investing activities were $57 million in 1997 compared
to $41 million and $120 million in 1996 and 1995, respectively. Acquisitions of
businesses, net of cash acquired, utilized $23 million in 1997 compared to a
source of cash of $1 million in 1996 and a use of cash of $71 million in 1995.
Acquisitions of businesses in 1997 were made to complement the Company's
capabilities in the areas of commercial information technology, transportation
and national security. Acquisitions of businesses in 1996 were made primarily
with the issuance of Company common stock. During 1996, the Company also spent
$21 million to acquire both direct and indirect equity interests in commercial
and international businesses. The Company intends to make additional
acquisitions in the future; however, the number and size of the acquisitions the
Company can complete may be limited due to the proposed acquisition of Bellcore.
Capital expenditures, excluding land and buildings, were $38 million, $33
million and $20 million in 1997, 1996 and 1995, respectively, and are expected
to be approximately $34 million for 1998. Expenditures for land and buildings
were $5 million, $1 million and $15 million in 1997, 1996 and 1995,
respectively, and are expected to be approximately $16 million for 1998.
 
     The Company utilized $10 million for financing activities in 1997 compared
to $10 million and $19 million in 1996 and 1995, respectively. In 1997, funds
were utilized primarily for common stock repurchases. Increase in common stock
repurchases in 1997 from 1996 was primarily attributable to increased
repurchases of common stock from the Company's Employee Stock Ownership Plan
("ESOP") in order for the ESOP to fund payouts to participants.
 
                                       17
<PAGE>   19
 
     The Company's cash flows from operations plus borrowing capacity are
expected to provide sufficient funds for the Company's operations, common stock
repurchases, capital expenditures and future long-term debt requirements.
However, the Company intends to obtain financing, including debt, to complete
the acquisition of Bellcore and expects to finance other acquisitions in the
future from operations and borrowing capacity as well as with the issuance of
Company common stock.
 
EFFECTS OF INFLATION
 
     The majority of the Company's contracts are cost-reimbursement type
contracts or are completed within one year. As a result, the Company has been
able to anticipate increases in costs when pricing its contracts. Bids for
longer term firm fixed-price and T&M type contracts typically include labor and
other cost escalations in amounts expected to be sufficient to cover cost
increases over the period of performance. Consequently, because costs and
revenues include an inflationary increase commensurate with the general economy,
net income, as a percentage of revenues, has not been significantly impacted by
inflation. As the Company expands into the international markets and into highly
inflationary economies, movements in foreign currency exchange rates may impact
the Company's results of operations. Currency exchange rate fluctuations may
also affect the Company's competitive position as a result of its impact on the
Company's profitability and the pricing offered to its non-U.S. customers.

Government; and other uncertainties, all of which are difficult to predict and
many of which are beyond the control of the Company. Due to such uncertainties
and risks, readers are cautioned not to place undue reliance on such
forward-looking statements, which speak only as of the date hereof.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Science Applications International Corporation
 
     In our opinion, the consolidated financial statements listed in the
accompanying index present fairly, in all material respects, the financial
position of Science Applications International Corporation and its subsidiaries
at January 31, 1997 and 1996, and the results of their operations and their cash
flows for each of the three years in the period ended January 31, 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Consolidation
 
     The consolidated financial statements include the accounts of Science
Applications International Corporation and all majority-owned U.S. and
international subsidiaries (collectively referred to as "the Company"). All
significant intercompany transactions and accounts have been eliminated in
consolidation. Investments in affiliates and corporate joint ventures owned
twenty to fifty percent are accounted for under the equity method. Other
investments are generally carried at cost.
 
     Certain of the Company's majority-owned subsidiaries have fiscal years
ending December 31. The financial position and results of operations of these
subsidiaries as of and for the year ending December 31 are included in the
Company's consolidated financial statements.
 
     On January 2, 1997, the Company formed a joint venture, Informatica,
Negocio y Tecnologia, S.A. ("INTESA"), with Venezuela's national oil company,
Petroleos de Venezuela, S.A., to provide information technology services in
Latin America. INTESA's fiscal year end is December 31; therefore, the Company
will begin to consolidate its 60% majority interest in INTESA in the
consolidated financial statements for the year ending January 31, 1998.
 
  Use of estimates
 
     The preparation of financial statements, in conformity with generally
accepted accounting principles, requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingencies at the date of the financial statements as well as
the reported amounts of revenues and expenses during the reporting period.
Estimates have been prepared on the basis of the most current and best available
information and actual results could differ from those estimates.
 
  Fair value of financial instruments
 
     It is management's belief that the carrying amounts shown for the Company's
financial instruments are reasonable estimates of their related values. The fair
value of the Company's long-term liabilities is estimated based on the current
rates offered to the Company for similar debt with the same remaining
maturities.
 
  Contract revenues
 
     The major portion of the Company's revenues result from contract services
performed for the U.S. Government or from subcontracts with other contractors
engaged in work for the U.S. Government under a variety of contracts, some of
which provide for reimbursement of cost plus fees and others which are fixed-
price or time-and-materials type contracts. Generally, revenues and fees on
contracts are recognized as services are performed, using the
percentage-of-completion method of accounting, primarily based on contract costs
incurred to date compared with total estimated costs at completion. Revenues
from the sale of manufactured products are recorded when the products are
shipped.
 
     The Company provides for anticipated losses on contracts by a charge to
income during the period in which the losses are first identified. Unbilled
receivables are stated at estimated realizable value. Contract costs, including
indirect costs, are subject to audit and adjustment by negotiations between the
Company and government representatives. Substantially all of the Company's
indirect contract costs have been agreed upon through 1995. Contract revenues
have been recorded in amounts that are expected to be realized upon final
settlement.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash and cash equivalents
 
     Cash equivalents are highly liquid investments purchased with an original
maturity of three months or less. Of the $45,279,000 and $22,765,000 total cash
and cash equivalents at January 31, 1997 and 1996, respectively, $16,161,000 and
$11,428,000, respectively, was invested in commercial paper.
 
  Investment securities
 
     Management determines the appropriate classification of its investments in
debt and equity securities at the time of purchase and reevaluates such
determinations at each balance sheet date. Debt securities are classified as
held to maturity or available for sale and are recorded at amortized cost and
fair value, respectively. As of January 31, 1997, the Company had $16,161,000 in
debt securities classified as held to maturity. As of January 31, 1996, the
Company had debt securities of $7,654,000 and $11,428,000 classified as
available for sale and held to maturity, respectively. Gross unrealized gains
and losses on the Company's available for sale securities were not significant.
 
  Restricted cash
 
     The Company's wholly-owned subsidiary Network Solutions, Inc. ("NSI") has
an agreement with the National Science Foundation which requires NSI to set
aside 30% of the cash collections from domain name registrations revenue to be
reinvested for the enhancement of the intellectual infrastructure of the
Internet. The Company also has a contract to provide support services to the
National Cancer Institute's Frederick Cancer Research and Development Center
("Center"). As part of the contract, the Company is responsible for paying for
materials, equipment and other direct costs of the Center through the use of a
restricted cash account which is pre-funded by the U.S. Government.
 
  Inventories
 
     Inventories are valued at the lower of cost or market. Cost is determined
using the moving average and first-in, first-out methods.
 
  Buildings, property and equipment
 
     Depreciation and amortization of buildings and related improvements are
provided using the straight-line method over estimated useful lives of thirty to
forty years and ten years, respectively. Depreciation and amortization of
property and equipment are provided over the estimated useful lives of the
assets, primarily using a declining-balance method. The useful lives are three
to ten years for equipment and the shorter of the useful lives or the terms of
the leases for leasehold improvements.
 
     Additions to property and equipment together with major renewals and
betterments are capitalized. Maintenance, repairs and minor renewals and
betterments are charged to expense. When assets are sold or otherwise disposed
of, the cost and related accumulated depreciation or amortization are removed
from the accounts and any resulting gain or loss is recognized.
 
  Long-lived assets
 
     The Company assesses potential impairments to its long-lived assets when
there is evidence that events or changes in circumstances have made recovery of
the asset's carrying value unlikely. An impairment loss would be recognized when
the sum of the expected future net cash flows is less than the carrying amount
of the asset.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Intangible assets
 
     Intangible assets consist primarily of goodwill. Goodwill represents the
excess of the purchase cost over the fair value of net assets acquired in an
acquisition and is amortized by the straight line method generally over five to
ten years. The carrying value of the Company's goodwill is reviewed when the
facts and circumstances suggest that they may be permanently impaired. If the
review indicates that the intangible assets may not be recoverable, as
determined by the undiscounted cash flow method, the assets will be reduced to
their estimated recoverable value. Amortization of intangible assets amounted to
$16,839,000, $11,044,000 and $6,257,000 in 1997, 1996 and 1995 respectively.
Accumulated amortization was $43,870,000 and $27,031,000 at January 31, 1997 and
1996, respectively.
 
   
     During 1997, the Company determined that there was evidence that events and
changes in circumstances have made recovery of certain goodwill unlikely. The
Company determined that $6,154,000 of the carrying value of goodwill was
impaired; accordingly, that amount was charged to income and included in
selling, general and administrative expense.
    
 
  Income taxes
 
     Income taxes are provided utilizing the liability method. The liability
method requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of temporary differences between the carrying
amounts and tax bases of assets and liabilities. Additionally, under the
liability method, changes in tax rates and laws will be reflected in income in
the period such changes are enacted.
 
  Stock-based compensation
 
     Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation," encourages, but does not require, companies to
record compensation expense for stock-based employee compensation plans at fair
value. The Company has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and
related interpretations. Accordingly, compensation expense for stock options is
measured as the excess, if any, of the fair value of the Company's stock as
determined by the Board of Directors at the date of grant over the amount an
employee must pay to acquire the stock (Note J).
 
  Common stock and earnings per share
 
     Class A and Class B common stock are collectively referred to as common
stock in the Notes to Consolidated Financial Statements unless otherwise
indicated.
 
     Computations of earnings per share are based on the weighted average number
of shares of common stock outstanding, increased by the effect of dilutive
options using the modified treasury stock method. Fully diluted earnings per
share was substantially the same as primary earnings per share in 1997, 1996 and
1995.
 
     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings per Share," which establishes standards for computing and
presenting earnings per share ("EPS"). SFAS No. 128 will be adopted by the
Company as required for the interim period and fiscal year ending January 31,
1998. Upon adoption of SFAS No. 128, the Company will present basic EPS as well
as diluted EPS in the period of adoption and restate all prior-period EPS data
presented for comparative purposes. Basic EPS will be computed by dividing
income available to common stockholders by the weighted average number of shares
of common stock outstanding. Diluted EPS will be computed similar to basic EPS
except that the weighted average number of shares of common stock outstanding
will be increased to include the number of additional common shares that would
have been outstanding if the dilutive potential common shares had been issued.
 
                                       F-9
<PAGE>   33
 
                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     A general public market for the Company's common stock does not exist.
Periodic determinations of the fair market value of the common stock are made by
the Board of Directors pursuant to a stock price formula and valuation process
which includes an appraisal prepared by an independent appraisal firm. The Board
of Directors reserves the right to alter the formula and valuation process.
 
  Other financial instruments
 
     The Company initiates hedging activities by entering into currency exchange
agreements consisting principally of currency forward contracts to minimize
revenue and cost variations which could result from fluctuations in currency
exchange rates. These instruments, consistent with the underlying purchase or
sale commitments, typically mature within seven years of origination. In the
event of an early termination of a currency agreement designated as a hedge, the
gain or loss will continue to be deferred and will be included in the settlement
of the underlying transaction. At January 31, 1997, the Company had
approximately $4,645,000 of foreign currency forward exchange contracts in
British pounds sterling and French francs outstanding with net deferred gains of
$170,000.
 
   
     In January 1997, the Company entered into forward treasury lock agreements
for a total of $200,000,000 which mature in October and November of 1997. Such
agreements were entered into to manage exposure to fluctuations in interest
rates on an anticipated, probable issuance of debt that will be used to finance
an anticipated, probable acquisition (Note B). Expected terms of the debt are
ten year fixed rate notes in the amount of $200,000,000. Gains or losses
resulting from the differential to be paid or received are deferred and will be
recorded as adjustments to interest expense over the term of the underlying
debt. In the event of an early termination of these contracts which have been
designated as hedges, the gain or loss will continue to be deferred and recorded
as an adjustment to interest expense over the remaining term of the underlying
debt.
    
 
     The currency exchange agreements and forward treasury lock agreements are
treated as off-balance sheet financial instruments with related gains and losses
recognized in earnings upon the settlement of the underlying transactions. The
Company does not enter into speculative or leveraged derivative transactions and
all agreements have been entered into with financial institutions which are
considered credit worthy.
 
  Concentration of credit risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents and
long-term investments. The Company invests its excess cash principally in U.S.
Government and municipal debt securities and commercial paper and has
established guidelines relative to diversification and maturities in an effort
to maintain safety and liquidity. These guidelines are periodically reviewed and
modified to take advantage of trends in yields and interest rates.
 
     Concentrations of credit risk with respect to receivables are limited
because the Company's primary customers are various agencies of the U.S.
Government as well as commercial customers engaged in work for the U.S.
Government. As of January 31, 1997, there were no significant concentrations of
receivables with these commercial customers.
 
  Foreign currency
 
   
     Financial statements of international subsidiaries, for which the
functional currency is the local currency, are translated into U.S. dollars
using the exchange rate at each balance sheet date for assets and liabilities
and a weighted average exchange rate for revenues, expenses, gains and losses.
Translation adjustments are recorded as a separate component of stockholders'
equity. The functional currency of the Company's foreign subsidiaries (INTESA,
SAIC Colombia, Limitada and SAIC de Mexico) that operate in a highly
inflationary economy is the U.S. dollar. The monetary assets and liabilities of
these foreign subsidiaries are translated into U.S. dollars at the exchange rate
in effect at the balance sheet date, while revenues, expenses, gains and losses
    
 
                                      F-10

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
are translated at the average exchange rate for the period, except for items
related to non-monetary assets and liabilities, which are translated at
historical rates. Resulting re-measurement gains or losses of these foreign
subsidiaries are recognized in the consolidated results of operations.
 
  Reclassifications
 
     Certain amounts from previous years have been reclassified in the
consolidated financial statements to conform to the 1997 presentation.
 
NOTE B -- ACQUISITIONS AND INVESTMENTS IN AFFILIATES:
 
     Acquisitions of certain business assets and companies have been accounted
for by the purchase method of accounting. The operations of the companies and
businesses acquired have been included in the accompanying consolidated
financial statements from their respective dates of acquisition. The excess of
the purchase price over fair value of the net assets acquired has been included
in intangible assets as goodwill. The aggregate effect of the purchased
acquisitions was not material to the Company's consolidated financial
statements.
 
     On November 20, 1996, the Company entered into a definitive acquisition
agreement to purchase Bell Communications Research, Inc. ("Bellcore"), a
provider of telecommunications services, information networking software and
consulting services. As of December 31, 1996, Bellcore had approximately 5,500
employees and annual revenues of approximately $1 billion. The consummation of
the acquisition is subject to certain conditions and contingencies, including
regulatory approvals which are expected to take between nine and fourteen months
to obtain from the date of the agreement. The Company intends to finance a
substantial portion of the purchase price of Bellcore with debt financing. In
anticipation of consummating the transaction, as part of the debt financing, the
Company entered into two forward treasury lock agreements, totaling $200 million
(Note A), which are intended to hedge against interest rate fluctuations.
 
     The carrying value of the Company's equity investments was $28,979,000 and
$25,016,000 at January 31, 1997 and 1996, respectively, which includes the
unamortized excess of the Company's investments over its equity in the
underlying net assets of $13,333,000 and $15,551,000, respectively.
 
NOTE C -- BUSINESS SEGMENT INFORMATION:
 
     The Company's principal business involves the application of scientific
expertise, together with computer and systems technology, to solve complex
technical problems for government agencies and industrial customers. The skills
of the professional staff encompass a variety of scientific and technical
disciplines and the management structure is based upon broad technological
groupings, not necessarily related to any particular industry, line of business,
geographical area, market or class of customer.
 
     For purposes of analyzing and understanding the Company's financial
statements, its operations have been classified into two broad segments:
Technical Services and Products. The Technical Services segment is further
classified between the National Security, Health, Environment, Energy and Other
business areas. Other business areas include commercial information technology,
transportation and space.
 
     Technical Services consist of applied and basic research; analysis and
development of new and existing policies, concepts, systems and programs; design
and development of computer software; systems engineering; systems integration;
test and evaluation of new products or systems; technical operational and
management support; environmental engineering; and engineering support to
existing facilities, laboratories and systems.
 
     Products include custom designed and standard hardware and software
products such as data display devices, "ruggedized" personal computers, sensors
and nondestructive imaging instruments. These products typically incorporate
Company-developed hardware and software as well as hardware and software
manufactured by others.

     Because of the nature of the Company's business, sales between segments are
not material. Segment operating results reflect general corporate expense
allocations because all such expenses are allocated to individual cost
objectives by the Company, as required by Government Cost Accounting Standards.
Identifiable assets of the respective industry segments consist of receivables,
inventories and goodwill. All other assets are either corporate in nature, are
not identifiable with particular segments or are not material. Capital
expenditures and depreciation and amortization are not identified as to industry
segments for similar reasons.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     During 1997, 1996 and 1995, approximately 79%, 83% and 86%, respectively,
of the Company's contract revenues were attributable to prime contracts with the
U.S. Government or to subcontracts with other contractors engaged in work for
the U.S. Government. Foreign operations and revenues directly attributable to
foreign customers were not material. In 1996, approximately 10% of the Company's
consolidated revenues were derived from one U.S. Government contract in the
Health business area, which is a contract to automate the information systems
for the Department of Defense's medical treatment facilities worldwide. This
contract was substantially completed in 1997. No single contract had revenues
greater than 10% of the Company's consolidated revenues in 1997 and 1995.
Subsequent to January 31, 1997, the Company sold a business unit which
manufactured data display devices and "ruggedized" personal computers and which
accounted for 49% of the Products revenue in 1997 (Note M).

     Unbilled receivables at January 31, 1997 and 1996 include $13,976,000 and
$20,586,000, respectively, related to costs incurred on projects for which the
Company has been requested by the customer to begin work under a new contract or
extend work under an existing contract, but for which formal contracts or
contract modifications have not been executed. These amounts have been included
in Technical Services revenues. The balance of unbilled receivables consist of
costs and fees billable on contract completion or other specified events, the
majority of which is expected to be billed and collected within one year.
Contract retentions are billed when the Company has negotiated final indirect
rates with the U.S. Government and, once billed, are subject to audit and
approval by outside third parties. Consequently, the timing of collection of
retention balances is outside the Company's control. Based on the Company's
historical experience, the majority of the retention balance is expected to be
collected beyond one year.
    
 
NOTE F -- REVOLVING CREDIT LOAN AGREEMENTS:
 
     The Company has substantially equivalent unsecured revolving credit loan
agreements with three banks with commitments totaling $105,000,000 which allow
borrowings on a revolving basis until March 31, 2000. The agreements enable
borrowings at various interest rates, at the Company's option, based on prime,
money market, certificate of deposit or interbank offshore borrowing rates.
Annual facility fees are 1/8 of 1% of the total commitment during the revolving
credit term.
 
     There were no balances outstanding under the credit loan agreements at
January 31, 1997, 1996 and 1995. As of January 31, 1997, the entire $105,000,000
was available under the most restrictive debt covenants of the credit loan
agreements. The maximum amounts outstanding were $31,000,000, $43,000,000 and
$12,800,000 in 1997, 1996 and 1995, respectively. The average amount outstanding
was $2,299,000, $9,380,000 and $197,000 during 1997, 1996 and 1995,
respectively. The weighted average interest rate in 1997, 1996 and 1995 was
5.9%, 6.4% and 4.9% respectively, based upon average daily balances.
 
NOTE G -- EMPLOYEE BENEFIT PLANS:
 
     In 1995, the Company merged two of its profit sharing retirement plans into
one principal Profit Sharing Retirement Plan (PSRP) in which eligible employees
participate. Participants' interests vest 25% per year in the third through
sixth year of service. Participants also become fully vested upon reaching age
59 1/2, permanent disability or death. Contributions charged to income under the
PSRP were $10,167,000, $23,355,000 and $27,420,000 for 1997, 1996 and 1995,
respectively.
 
     The Company has an Employee Stock Ownership Plan (the "Plan") in which
eligible employees participate. Cash contributions to the Plan are based upon
amounts determined annually by the Board of Directors and are allocated to
participants' accounts based on their annual compensation. The Company
recognizes compensation expense as the fair value of the Company common stock or
cash in the year of contribution. The vesting requirements for the Plan are the
same as the PSRP. Shares of Company common

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
stock distributed from the Plan bear a limited put option that, if exercised,
would require the Company to repurchase the shares at their then current fair
value. At January 31, 1997, the Plan held 15,482,000 shares of Class A common
stock and 30,000 shares of Class B common stock with a combined fair value of
$405,807,000. Contributions charged to income under the Plan were $29,492,000,
$10,259,000 and $10,516,000 for 1997, 1996 and 1995, respectively.
 
     The Company has one principal Cash or Deferred Arrangement (CODA) which
allows eligible participants to defer a portion of their income through
contributions. Such deferrals are fully vested, are not taxable to the
participant until distributed from the CODA upon termination, retirement,
permanent disability or death and may be matched by the Company. The Company's
matching contributions to the CODA of $9,567,000, $11,535,000 and $10,977,000
were charged to income in 1997, 1996 and 1995, respectively. Effective January
1, 1995, the Company's matching contributions to employees hired on or after
such date are subject to the same vesting requirements as the PSRP, while the
Company's matching contributions for employees hired prior to such date remain
fully vested.
 
     The Company has a Bonus Compensation Plan which provides for bonuses to
reward outstanding performance. Bonuses are paid in the form of cash, fully
vested shares of Class A common stock or vesting shares of Class A common stock.
Awards of vesting shares of Class A common stock made prior to July 10, 1992,
vest at the rate of 10%, 20%, 30% and 40% after one, two, three and four years,
respectively, from the date of award. Awards of vesting shares of Class A common
stock made after July 10, 1992, vest at the rate of 20%, 20%, 20% and 40% after
one, two, three and four years, respectively. The amounts charged to income
under this plan were $32,359,000, $25,868,000 and $23,831,000 for 1997, 1996 and
1995, respectively.
 
     In 1995, the Company adopted the Stock Compensation Plan and the Management
Stock Compensation Plan, together referred to as the "Stock Compensation Plans."
The Stock Compensation Plans provide for awards of share units to eligible
employees, which share units generally correspond to shares of Class A common
stock which are held in trust for the benefit of participants. Participants'
interests in these share units vest on a seven year schedule at the rate of
one-third at the end of each of the fifth, sixth and seventh years following the
date of the award. The fair market value of shares awarded under these plans are
recorded as unearned compensation and included as a separate component of
stockholders' equity. The unearned amounts are amortized to expense over the
vesting period. The amounts charged to income under these plans were $1,282,000,
$686,000 and $160,000 for 1997, 1996 and 1995, respectively.
 
   
     The Company also has an Employee Stock Purchase Plan which allows eligible
employees to purchase shares of the Company's Class A common stock, with the
Company contributing 5% of the existing fair market value in 1997. There are no
charges to income under this plan. Effective for 1998, the Company increased its
contribution to 10% and will not recognize compensation expense but disclose the
proforma effect on net income and earnings per share (Note J).

     During 1997, the Company assumed a $6,919,000 mortgage note in connection
with the purchase of land and building. Terms of the note include quarterly
payments of principal and interest until December 2016. Interest is adjusted
annually and was 6.4% in 1997. In connection with the purchase of land and a
building in 1991, the Company assumed a mortgage note of $12,800,000. Terms of
this note include an 8.9% interest rate and monthly payments of principal and
interest of $102,000 until June 1997 when the remaining principal balance
becomes due.
 
     The Company has two deferred compensation plans. The Keystaff Deferral Plan
is maintained for the benefit of key executives and directors, pursuant to which
eligible participants may elect to defer a portion of their compensation. The
Company makes no contributions to the accounts of participants under this plan
but does credit participant accounts for deferred compensation amounts and
interest earned on such deferred compensation. Interest is accrued based on the
Moody's Seasoned Corporate Bond Rate (7.6% in 1997). Deferred balances will
generally be paid upon the later of the attainment of age 65, ten years of plan
participation or retirement, unless participants elect an early pay-out. The Key
Executive Stock Deferral Plan is maintained for the benefit of directors and
certain key executives. Eligible participants may elect to defer a portion of
their compensation into a trust established by the Company which invests in
shares of Class A common stock. The Company makes no contributions to the
accounts of participants. Deferred balances will generally be paid upon
retirement or termination of affiliation.
 
     In connection with a business acquisition completed in 1997, the Company
assumed liability for a $14,400,000 note due in December 1999. Other terms of
the note include monthly payments of principal and interest at 7.0%. The Company
has various other notes with interest rates from 4.3% to 8.0% that are due over
the next twelve years.

NOTE J -- COMMON STOCK AND OPTIONS:
 
     The Company has options outstanding under three stock option plans, the
1995 Stock Option Plan (the 1995 Plan), which was adopted effective July 14,
1995, the 1992 Stock Option Plan (the 1992 Plan) and the 1982 Stock Option Plan
(the 1982 Plan). Under the 1995, 1992 and 1982 Plans, options are granted at
prices not less than the fair market value at the date of grant and for terms
not greater than ten years. Options granted prior to July 10, 1992 generally
become exercisable 10%, 20%, 30% and 40% after one, two, three and four years,
respectively, from the date of grant. Options granted after July 10, 1992
generally become exercisable 20%, 20%, 20% and 40% after one, two, three and
four years, respectively, from the date of grant. No options have been granted
under the 1992 Plan after July 31, 1995 and the 1982 Plan after July 10, 1992,
the dates the plans terminated, respectively. The Company makes no charge to
income in connection with these plans.
 
     The Company adopted SFAS No. 123, "Accounting for Stock-Based Compensation"
during 1997. In accordance with the provisions of SFAS No. 123, the Company
applies Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued
to Employees," and related interpretations in accounting for its plans and does
not recognize compensation expense for its employee stock-based compensation
plans. If the Company had elected to recognize compensation expense based upon
the fair value at the grant dates for stock option awards granted in 1997 and
1996, consistent with the methodology prescribed by SFAS No. 123, net income and
earnings per share in 1997 would have been reduced by $4,797,000 and $.08 per
share, respectively. For 1996, net income and earnings per share would have been
reduced by $2,273,000 and $.04 per share, respectively. These amounts were
determined using weighted-average per share fair values of options granted in
1997 and 1996 of $5.30 and $4.59, respectively. The fair value for these options
was estimated at the date of grant using the Black-Scholes option pricing model
with the following assumptions for 1997 and 1996, respectively; no dividend
yields, no volatility, risk free interest rates ranging from 5.3% to 7.2%, and
expected lives of five years.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. The Company meets the definition of a non-public company for the
purposes of calculating fair value and, therefore, assumes no volatility in the
fair value calculation. Because the Company's employee stock options have
characteristics significantly different from those of traded options and because
changes in subjective input assumptions can materially affect the fair value
estimates, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock-based
compensation plans.

NOTE K -- COMMITMENTS AND CONTINGENCIES:
 
     The Company occupies most of its facilities under operating leases. Most of
the leases require the Company to pay maintenance and operating expenses such as
taxes, insurance and utilities and also contain renewal options extending the
leases from one to twenty years. Certain of the leases contain purchase options
and provisions for periodic rate escalations to reflect cost-of-living
increases. Certain equipment, primarily computer-related, is leased under
short-term or cancelable leases. Rental expenses for facilities and equipment
totaled $68,334,000, $63,282,000 and $58,538,000 in 1997, 1996 and 1995,
respectively.

     The Company leases a general purpose office building and has guaranteed a
$12,250,000 loan on behalf of the building owner. Certain financial ratios and
balances required by the guarantee have been maintained.
 
     Other commitments at January 31, 1997 include outstanding letters of credit
aggregating $23,464,000, principally related to guarantees on contracts with
commercial and foreign customers, and outstanding surety bonds aggregating
$158,450,000, principally related to performance and payment type bonds.
 
     The Company is involved in various investigations, claims and lawsuits
arising in the normal conduct of its business, none of which, in the opinion of
the Company's management, will have a material adverse effect on its
consolidated financial position, results of operations, cash flows or its
ability to conduct business.
 
NOTE L -- SUPPLEMENTARY INCOME STATEMENT INFORMATION:
 
     Charges to costs and expenses for depreciation and amortization of
buildings, property and equipment were $31,790,000, $25,956,000 and $21,481,000
for 1997, 1996 and 1995, respectively.
 
     The Company expensed $11,145,000, $10,258,000 and $8,490,000 of independent
research and development costs during 1997, 1996 and 1995, respectively.
 
     Total interest paid in 1997, 1996 and 1995 amounted to $3,495,000,
$2,746,000 and $1,514,000, respectively.
 
NOTE M -- SUBSEQUENT EVENT:
 
     On March 7, 1997, the Company sold the majority of the net assets of the
SAIT business unit to Litton Systems, Inc. The purchase price is subject to
potential adjustments, plus contingent payments if certain milestones are
achieved by the business post-closing. Under the agreement, the Company also
retains certain contingent liabilities. Given the early stage of the settlement
period, the impact of the sale on the consolidated financial position and
results of operations has not been determined. The Company, however, does not
anticipate a loss on the sale.
