                                     PART I

ITEM 1. BUSINESS

                                  THE COMPANY

     Science Applications International Corporation (the "Company") primarily
provides diversified professional and technical services involving the
application of scientific expertise, together with computer and systems
technology, to solve complex technical problems for a broad range of government
and commercial customers, both in the U.S. and abroad. Technical services
consist of basic and applied research services; design and development of
computer software; systems integration; systems engineering; technical
operational and management support services; environmental engineering; design
and integration of network systems; technical engineering and consulting support
services; and development of systems, policies, concepts and programs. In
addition to providing technical services, the Company designs and develops
high-technology products. These products include customized and standard
hardware and software, such as automatic equipment identification technology,
sensors and nondestructive imaging instruments.

     Through its subsidiary, Telcordia Technologies, Inc. (formerly Bell
Communications Research, Inc.) ("Telcordia"), the Company is a global provider
of software, engineering and consulting services, advanced research and
development, technical training and other services to the telecommunications
industry.

     The Company provides technical services primarily in the vertical market
areas of "National Security," "Health Care," "Environment," "Energy,"
"Telecommunications," "Information Technology" and a group of general market
categories hereinafter referred to as "Other," which includes the Company's
transportation, logistics, space and utilities business areas and information
technology support to federal civil agencies. The Company's operating groups
("Groups") are divided into two segments, Regulated and Non-Regulated, depending
on the business processes and laws affecting the operations of the Groups. While
the Regulated and Non-Regulated segments represent the management approach for
making decisions and assessing performance, the Company's decentralized
marketing approach focuses on its key vertical markets. Marketing decisions
based on vertical markets are typically made at the lowest operational level.

     Groups in the Regulated segment provide technical services and products
through contractual arrangements as either a prime contractor or a subcontractor
to other contractors, primarily for departments and agencies of the U.S.
Government, including the Department of Defense, Department of Energy,
Department of Health and Human Services, Department of Justice, Department of
Transportation, Department of Treasury, Department of Veterans Affairs,
Environmental Protection Agency and National Aeronautics and Space
Administration. Operations in the Regulated segment are subject to specific
regulatory accounting and contracting guidelines such as "Cost Accounting
Standards" and "Federal Acquisition Regulations." The Regulated segment includes
business from all of the Company's vertical market areas. The percentage of
revenues attributable to the Regulated segment for fiscal years 2000, 1999 and
1998 were 59%, 58% and 74%, respectively.

     Groups in the Non-Regulated segment provide technical services and products
primarily to customers in commercial markets. Generally, operations in the
Non-Regulated segment are not subject to specific regulatory accounting or
contracting guidelines. The Non-Regulated segment includes business from all of
the Company's vertical market areas except for National Security and Space
(which is part of the "Other" vertical market). The percentage of revenues
attributable to the Non-Regulated segment for fiscal years 2000, 1999 and 1998
were 40%, 42% and 25%, respectively. For certain other financial information
regarding the Company's reportable segments and geographic areas, see Note C of
the Notes to Consolidated Financial Statements of the Company on page F-14 of
this Form 10-K.

     The Company holds its equity investment interests in publicly traded and
private emerging technology companies in a newly formed wholly-owned subsidiary
called SAIC Venture Capital Corporation ("SAIC Venture Capital"). On February
11, 2000, SAIC Venture Capital sold 6,700,000 shares of Class A Common Stock of
Network Solutions, Inc. ("NSI") in a secondary public offering. Prior to the
secondary offering, SAIC Venture Capital had approximately a 44.7% ownership
interest in NSI. On March 10, 2000, NSI

                                        2
<PAGE>   3

completed a 2-for-1 stock split. Subsequent to the stock split and the sale,
SAIC Venture Capital currently owns 16,300,000 shares of NSI's Class A Common
Stock, which represents approximately 22.6% of the outstanding stock of NSI. NSI
provides Internet domain name registration services and Intranet consulting and
network design and implementation services. On March 6, 2000, NSI entered into a
merger agreement with VeriSign, Inc. ("VeriSign"), a publicly traded company and
leading provider of Internet trust services, pursuant to which VeriSign would
acquire NSI and NSI would become a wholly-owned subsidiary of VeriSign. Under
the merger agreement, VeriSign will issue 1.075 shares of VeriSign common stock
for each share of NSI stock (after giving effect to the 2-for-1 split of NSI
common stock completed on March 10, 2000). This merger would result in the
Company holding approximately 9% of VeriSign's outstanding shares. The
transaction is expected to close in the third quarter of calendar 2000, subject
to obtaining the approval of the stockholders of VeriSign and NSI and necessary
regulatory approvals.

     The Company holds 60% of the common stock of a joint venture, Informatica,
Negocios y Tecnologia, S.A. ("INTESA"), which was formed with Venezuela's
national oil company, Petroleos de Venezuela, S.A. INTESA provides information
technology services in Latin America.

     The Company was originally incorporated as a California corporation in 1969
and was re-incorporated as a Delaware corporation in 1984. The principal office
and corporate headquarters of the Company are located in San Diego, California
at 10260 Campus Point Drive, San Diego, California 92121 and its telephone
number is (858) 826-6000. All references to the Company include, unless the
context indicates otherwise, its predecessor and subsidiary corporations.

TECHNICAL SERVICES

     The Company provides technical services to its customers in the vertical
market areas listed below. Technical services are sold to government and
commercial customers in both the Regulated and Non-Regulated segments, except
that technical services in the National Security and Space vertical markets are
provided to government customers and reported only in the Regulated segment.

  National Security

     The Company provides a wide array of national security-related technical
services to its government customers only in the Regulated segment. Such
services include advanced research and technology development, systems
engineering and systems integration and technical, operational and management
support services.

  Health

     The Company provides health-related technical services, including medical
information systems, technology development and research support services.

  Environment

     In the environmental area, the Company performs site assessments, remedial
investigations and feasibility studies, remedial actions, technology
evaluations, sampling, monitoring and regulatory compliance support and
training.

  Energy

evaluations, security, reliability and availability engineering evaluations,
technical reviews, quality assurance, information systems, plant monitoring
systems and project management.

                                        3
<PAGE>   4

  Telecommunications

     In the telecommunications area, the Company provides interoperable network
design and implementation, new software and enhancements of existing software
for network management and operation, consulting and engineering services and
telecommunications software.

  Information Technology

     The information technology-related technical services of the Company
include information technology outsourcing services, information protection and
electronic business security services, Intranet consulting and network design
services.

  Other Technical Services

     The Company provides technical services in transportation, space, and
security systems management, including advanced traffic and intermodal freight
management, material control and computer and information security, engineering
support for NASA's Space Shuttle and Space Station programs, and undersea data
collection, transmission and analysis systems and services. The Company also
provides technical services to law enforcement agencies and educational
organizations.

                                   RESOURCES

     The technical services and products provided by the Company to government
and commercial customers in both the Regulated and Non-Regulated segments
utilize a wide variety of resources. A substantial portion of the computers and
other equipment, materials and subcontracted work required by the Company can be
procured from more than one supplier. 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 any affected
program or product, the Company believes it would not have a material adverse
effect on the financial condition 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.
Competition for personnel in the commercial information technology area of the
Non-Regulated segment is intense. Because of the Company's growth and the
competition for experienced personnel, it has become more difficult to meet all
of the Company's needs for such employees in a timely manner. However, such
difficulties have not had a significant impact on the Company to date. The
Company intends to continue to devote significant resources to recruit and
retain qualified employees. Further, as an inducement, the Company maintains a
variety of benefit programs for its employees, including retirement and bonus
plans, group life, health, accident and disability insurance as well as the
opportunity to participate in the Company's employee ownership program. See
"Business -- Employees And Consultants" and "Market for Registrant's Common
Equity and Related Stockholder Matters -- The Limited Market."

                                   MARKETING

     The Company's marketing activities in both the Regulated and Non-Regulated
segments are focused on its key vertical markets and 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 its
government, commercial and other potential customers for the types of technical
services provided by the Company. Such information is gathered in the course of
contract performance, reviewing requests for competitive bids, 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

                                        4
<PAGE>   5

needs of customers. The Company's products may be marketed with the assistance
of independent sales representatives.

                                  COMPETITION

     The businesses in which the Company is engaged are highly competitive,
particularly in the business areas of telecommunications and information
technology outsourcing in the Non-Regulated segment. 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 and able to concentrate their resources on particular areas.
In addition, with respect to the Regulated segment, the U.S. Government's own
in-house capabilities and federal non-profit contract research centers also
compete with the Company because they perform certain types of services which
might otherwise be performed by the Company.

     The Company competes on the basis of technical expertise, management and
marketing abilities 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 fiscal years 2000, 1999 and 1998, approximately 52%, 50% and 66%,
respectively, of the Company's consolidated revenues were attributable to prime
contracts (as more fully described below) with the U.S. Government, a
significant customer in the Regulated segment, or to subcontracts with other
contractors engaged in work for the U.S. Government.

     No single customer or contract in the Non-Regulated segment accounted for
10% or more of consolidated revenues in fiscal years 2000, 1999 or 1998.

                              GOVERNMENT CONTRACTS

     The U.S. Government is the Company's primary customer in the Regulated
segment. 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 is
reimbursed for its allowable costs through the date of termination and is paid a
proportionate amount of the stipulated profit or fee attributable to the work
actually performed.

     Although contract and program modifications, curtailments or terminations
have not had a material adverse effect on the Company in the past, no assurance
can be given that such modifications, curtailments or terminations will not have
a material adverse effect on the financial condition or results of operations of
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 up to a fixed ceiling. 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 a set price, the failure to accurately estimate
ultimate costs or to control costs during the contract performance could result,
and in some instances has resulted, in reduced profits or losses for particular
contracts.

                                        5
<PAGE>   6

     During fiscal years 2000, 1999 and 1998, approximately 55%, 60% and 63%,
respectively, of the Regulated segment revenues were derived from
cost-reimbursement contracts and approximately 15%, 15% and 18%, respectively,
of the Regulated segment revenues were from firm fixed-price contracts, with the
balance from time-and-materials and fixed-price level of effort 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 that were included in the Regulated segment revenues, exclusive of
related fees, at January 31, 2000 and 1999 were $25,743,000 and $18,863,000,
respectively. The Company expects to recover substantially all such costs;
however, no assurance can be given that the contracts or contract amendments
will be executed 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 as a
result of negotiations between the Company and U.S. Government representatives.
Substantially all of the Company's indirect contract costs have been agreed upon
through fiscal year 1999. Contract revenues for subsequent years have been
recorded in amounts which are expected to be realized upon final settlement with
the U.S. Government. 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

     Other than the business and operations of Telcordia described below, 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.

     Telcordia's patent portfolio consists of more than 1,000 U.S. and foreign
patents. More than 200 of these patents have been licensed to organizations
worldwide. Telcordia has been granted patents across a wide range of
disciplines, including telecommunications transmission, services and operations,
optical networking, switching, wireless communications, protocols, architecture
and coding. The Company and Telcordia actively pursue opportunities to license
their technologies to third parties and evaluate potential spin-offs of
technologies that they have developed.

     In connection with the performance of services for customers in the
Regulated segment, 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 Regulated segment at January 31, 2000 and 1999 was
approximately $1,742,000,000 and $1,663,000,000, respectively, and the backlog
for the Non-Regulated segment at those dates was approximately $1,601,000,000
and $1,278,000,000, respectively. The Company expects that a substantial

                                        6
<PAGE>   7

portion of its backlog at January 31, 2000 will be recognized as revenues prior
to January 31, 2001. Some contracts associated with the backlog are
incrementally funded and may continue for more than one year.

                           EMPLOYEES AND CONSULTANTS

     As of January 24, 2000, the Company and its subsidiaries employed
approximately 39,078 persons. The Company also utilizes the services of
consultants to provide specialized technical and other services on specific
projects. To date, no strikes or work stoppages have been experienced and the
Company considers its relations with its employees to be good.

     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. Competition for
personnel in the commercial information technology area of the Non-Regulated
Segment is intense. Because of the Company's growth and competition for
experienced personnel, it has become more difficult to meet all of the Company's
needs for such employees in a timely manner. However, such difficulties have not
had a significant impact on the Company to date. The Company intends to continue
to devote significant resources to recruit and retain qualified employees.
Management believes that the Company's employee ownership programs and
philosophy are major factors in the Company's ability to attract and retain
qualified personnel.

                                  RISK FACTORS

     You should carefully consider the risks and uncertainties described below
in your evaluation of us and our business. These are not the only risks and
uncertainties that we face. If any of these risks or uncertainties actually
occur, our business, financial condition or operating results could be
materially harmed and the price of our common stock could decline. All
references to "we," "us," or "our" in this section include the Company and its
subsidiaries.

RISKS RELATING TO OUR BUSINESS

A SUBSTANTIAL PERCENTAGE OF OUR REVENUE IS FROM U.S. GOVERNMENT CUSTOMERS AND
THE REGIONAL BELL OPERATING COMPANIES

     We derive a substantial portion of our revenues from the U.S. Government in
our capacity as a prime contractor or a subcontractor. The percentage of total
revenues from the U.S. Government was 52% in fiscal year 2000, 50% in fiscal
year 1999 and 66% in fiscal year 1998. Our revenues could be adversely impacted
by a reduction in the overall level of U.S. Government spending and by changes
in its spending priorities from year to year. Furthermore, even if the overall
level of U.S. Government spending does increase or remains stable, the budgets
of the government agencies with whom we do business may be deceased or our
projects with them may not be sufficiently funded, particularly because Congress
usually appropriates funds for a given project on a fiscal-year basis even
though contract performance may take more than one year. In addition, obtaining
U.S. Government contracts continues to be competitive as our revenue growth
shifts toward contracts with lower reimbursable costs.

     Telcordia has historically derived a majority of its revenues from the
regional Bell operating companies, which we call "RBOCs". The percentage of
total Telcordia revenues from the RBOCs was 53% in fiscal year 2000 and 62% in
fiscal year 1999. In order for Telcordia to maintain or exceed historical growth
rates, it will need to continue to increase its market share from the RBOCs
and/or diversify its business by obtaining new customers. Loss of business from
the RBOCs could reduce revenues.

     We have made progress in our efforts to diversify our business across a
greater number of customers. However, we still remain heavily dependent upon the
U.S. Government as our primary customer in our Regulated segment and the RBOCs
are a major source of Telcordia revenues. Our future success and revenue growth
will depend in part upon our ability to continue to expand our customer base.

WE MAY NOT BE ABLE TO IMPLEMENT OUR ACQUISITION STRATEGY

     We have historically supplemented our internal growth through acquisitions,
investments or joint ventures. We evaluate potential acquisitions, investments
and joint ventures on an ongoing basis. Our acquisition and investment strategy
poses many risks, including:

     - We may not be able to compete successfully for available acquisition
       candidates, complete future acquisitions and investments or accurately
       estimate their financial effect on our business

     - Future acquisitions, investments and joint ventures may require us to
       issue additional common stock, spend significant cash amounts or decrease
       our operating income

     - We may have trouble integrating the acquired business and retaining their
       personnel

     - Acquisitions, investments or joint ventures may disrupt our business and
       distract our management from other responsibilities

     - To the extent that any of the businesses which we acquire or in which we
       invest fail, our business could be harmed

WE MAY SUFFER ADVERSE CONSEQUENCES IF WE ARE DEEMED TO BE AN INVESTMENT COMPANY

     We believe that we are actively engaged in the business of providing
professional and technical scientific services, together with computer and
systems technology, to our customers. However, as a result of recent

                                        8
<PAGE>   9

investments by our wholly-owned subsidiary, SAIC Venture Capital Corporation,
and the sale of our NSI stock, we may be deemed to be an investment company in
the future. Investment companies are subject to registration under, and must
operate in compliance with, the Investment Company Act of 1940 unless a
particular exclusion or exemption applies. Although we currently are not
required to register under this Act, fluctuations in the value of our
investments or of our other assets may subject us to registration. As a result,
we may be required to take various precautionary steps to avoid registration,
including the disposition or acquisition of certain assets, which might not
otherwise be taken. It would not be feasible for us to be regulated as an
investment company because the Investment Company Act rules are inconsistent
with our business strategy.

WE FACE INCREASING RISKS ASSOCIATED WITH OUR GROWING INTERNATIONAL BUSINESS

     Our revenues from customers outside the U.S. are expected to continue to
increase in the future. Consequently, we are increasingly subject to the risks
of conducting business internationally. These risks include:

     - unexpected changes in regulatory requirements

     - tariffs

     - political and economic instability

     - restrictive trade policies

     - inconsistent product regulation

     - cost of complying with a variety of laws

     - licensing requirements

     We do not know the impact that such regulatory, geopolitical and other
factors may have on our business in the future.

     We have transactions denominated in foreign currencies because some of our
business is conducted outside of the United States. In addition, our foreign
subsidiaries generally conduct business in foreign currencies. We are exposed to
fluctuations in exchange rates, which could result in losses and have a
significant impact on our results of operations. This risk may be significant
for entities such as INTESA, a Venezuelan joint venture in which we own 60%,
that operate in a highly inflationary economy. Our risks include the possibility
of significant changes in exchange rates and the imposition or modification of
foreign exchange controls by either the U.S. or applicable foreign governments.
We have no control over the factors that generally affect these risks, such as
economic, financial and political events and the supply and demand for the
applicable currencies. We may use forward foreign currency exchange rate
contracts to hedge against movements in exchange rates for contracts denominated
in foreign currencies. We cannot assure you that a significant fluctuation in
exchange rates will not have a significant negative impact on our results of
operations.

DEPENDENCE UPON SERVICES OF DR. BEYSTER AND OTHER KEY PERSONNEL

     Our success to date has been a result of the contributions of our founder
and chief executive officer, J.R. Beyster (age 75), and, to a lesser extent, our
other executive officers. Dr. Beyster and these executive officers are expected
to continue to make important contributions to the Company's success. The loss
of any of these key personnel could materially affect our operations. We
generally do not have long-term employment contracts with these key personnel
nor do we maintain "key person" life insurance policies.

WE FACE RISKS RELATING TO GOVERNMENT CONTRACTS

     The Government may Modify, Curtail or Terminate our Contracts. Many of the
U.S. Government programs in which we participate as a contractor or
subcontractor may extend for several years; however, such programs are normally
funded on an annual basis. The U.S. Government may modify, curtail or terminate
its

                                        9
<PAGE>   10

contracts and subcontracts at its convenience. Modification, curtailment or
termination of our major programs or contracts could have a material adverse
effect on our results of operations and financial condition.

     Our Business is Subject to Potential Government Inquiries and
Investigations. We are from time to time subject to certain U.S. Government
inquiries and investigations of our business practices due to our participation
in government contracts. We cannot assure you that any such inquiry or
investigation would not have a material adverse effect on our results of
operations and financial condition.

     Our Contract Costs are Subject to Audits by Government Agencies. The costs
we incur on our U.S. Government contracts, including allocated indirect costs,
may be audited by U.S. Government representatives. These audits may result in
adjustments to our contract costs. We normally negotiate with the U.S.
Government representatives before settling on final adjustments to our contract
costs. Substantially all of our indirect contract costs have been agreed upon
through fiscal year 1999. We have recorded contract revenues in fiscal year 2000
based upon costs we expect to realize upon final audit. However, we do not know
the outcome of any future audits and adjustments and we may be required to
reduce our revenues or profits upon completion and final negotiation of these
audits.

FAILURE TO CONTROL FIXED-PRICE CONTRACTS MAY RESULT IN REDUCED PROFITS OR LOSSES

     The percentage of our Regulated segment revenues from firm fixed-price
contracts was 15% for fiscal year 2000, 15% for fiscal year 1999 and 18% for
fiscal year 1998. The percentage of our Non-Regulated segment revenues from firm
fixed-price contracts was 77% for fiscal year 2000, 71% for fiscal year 1999 and
73% for fiscal year 1998. Because we assume the risk of performing a firm
fixed-price contract at a set 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 such contracts.

PRE-CONTRACT COSTS MAY NOT BE RECOVERED

     Any costs we incur before the execution of a contract or contract amendment
are incurred at our risk, and it is possible that the customer will not
reimburse us for such costs. At January 31, 2000, we had unbilled receivables of
$25,743,000 included in the Regulated segment revenues and $912,000 included in
the Non-Regulated segment revenues, exclusive of related fees for such
pre-contract costs. We cannot assure you that contracts or contract amendments
will be executed or that the related costs will be recovered.

RISKS RELATING TO OUR INDUSTRY

WE MUST ATTRACT, TRAIN AND RETAIN SKILLED EMPLOYEES

     The availability of highly trained and skilled professional, administrative
and technical personnel is critical to our future growth and profitability.
Competition for scientists, engineers, technicians, management and professional
personnel is intense and competitors aggressively recruit key employees. Because
of our growth and competition for experienced personnel, it has become more
difficult to meet all of our needs for such employees in a timely manner. We
intend to continue to devote significant resources to recruit, train and retain
qualified employees; however, we cannot assure you that we will be able to
attract and retain such employees on acceptable terms. Any failure to do so
could have a material adverse effect on our operations.

OUR FAILURE TO REMAIN COMPETITIVE COULD HARM OUR BUSINESS

     Our business is highly competitive, particularly in the business areas of
telecommunications and information technology outsourcing in our Non-Regulated
segment. We compete with larger companies that have greater financial resources
and larger technical staffs. We also compete with smaller, more specialized
entities who are able to concentrate their resources on particular areas. In the
Regulated segment, we also compete with the U.S. Government's own in-house
capabilities and federal non-profit contract research centers. To continue our
success, we must provide superior service and performance on a cost-effective
basis.

RISKS RELATING TO OUR STOCK

NO PUBLIC MARKET EXISTS FOR OUR STOCK AND STOCKHOLDERS' ABILITY TO SELL OUR
STOCK IS LIMITED

     There is no public market for the Class A common stock. The limited market
maintained by our wholly-owned broker-dealer subsidiary, Bull, Inc., permits
existing stockholders to offer our stock for sale only on predetermined trade
dates. Generally, there are four trade dates each year. If there are
insufficient buyers for the stock on any trade date, our stockholders may not be
able to sell stock on the trade date. We are authorized but not obligated to
purchase shares of Class A common stock in the limited market on any trade date,
and, accordingly, our stockholders may be unable to sell all the shares they
desire to sell.

OUR STOCK PRICE IS DETERMINED BY OUR BOARD OF DIRECTORS AND IS NOT ESTABLISHED
BY MARKET FORCES

     Our stock price is not determined by a trading market of bargaining buyers
and sellers. Our board of directors determines the price at which the Class A
common stock trades by using the valuation process described under "Price Range
of Class A Common Stock and Class B Common Stock." Our board of directors
believes the stock price represents a fair market value; however, we cannot
assure you that the stock price represents the value that would be obtained if
our stock was publicly traded. The formula referred to on page 17, which is one
part of the valuation process, does not specifically include variables
reflecting all financial and valuation criteria that may be relevant. In
addition, our board of directors generally has broad discretion to modify the
formula. Absent changes in the market factor used in the formula, which may
change considerably from quarter to quarter as appropriate to reflect changing
business, financial and market conditions, the mechanical application of the
formula tends to reduce the impact of quarterly fluctuations in our operating
results on the stock price because the formula takes into account our net income
for the four preceding quarters.

FUTURE RETURNS ON OUR COMMON STOCK MAY DIFFER SIGNIFICANTLY FROM HISTORICAL
RETURNS

     We cannot assure you that the Class A common stock will provide returns in
the future comparable to those achieved historically or that the price will not
decline.

CHANGES IN OUR BUSINESS MAY INCREASE THE VOLATILITY OF THE STOCK PRICE

     The stock price could be subject to greater fluctuations than it has
experienced in the past. The increased volatility is expected to result from the
impact on our stock price of:

     - our ownership interest in publicly traded companies. As our ownership of
       securities of publicly traded companies continues to increase, our stock
       price will be affected by the volatility of the price of those companies'
       shares

     - the increase of our commercial and international business as a proportion
       of our overall business and the greater volatility associated with
       companies in those business areas

     - the impact of acquisitions, investments and joint ventures that we may
       pursue in the future

     Finally, the market factor used in the formula may change considerably from
quarter to quarter, as appropriate, to reflect changing business, financial and
market conditions.

THE ABILITY OF A STOCKHOLDER TO SELL OR TRANSFER OUR COMMON STOCK IS RESTRICTED

     Our certificate of incorporation limits our stockholders' ability to sell
or transfer shares of Class A common stock in some circumstances. These
restrictions include:

     - our right of first refusal to purchase shares a stockholder offers to
       sell to a third party other than in our limited market

     - our right to repurchase shares upon the termination of a stockholder's
       employment or affiliation with us

                                       11
<PAGE>   12

     The repurchase restriction does not apply to employees who qualify for the
Company's Alumni Program and who elect to have us defer our repurchase rights
for five years.

RESTRICTIONS IN OUR CERTIFICATE OF INCORPORATION AND BYLAWS MAY DISCOURAGE
TAKEOVER ATTEMPTS THAT YOU MIGHT FIND ATTRACTIVE

     Our certificate of incorporation and bylaws may discourage or prevent
attempts to acquire control of us that are not approved by our board of
directors, including transactions in which stockholders might receive a premium
for their shares above the stock price. Our stockholders may view such a
takeover attempt favorably. In addition, the restrictions may make it more
difficult for our stockholders to elect directors not endorsed by the Company.

FORWARD-LOOKING STATEMENT RISKS

YOU MAY NOT BE ABLE TO RELY ON FORWARD-LOOKING STATEMENTS

     The information contained in this report or in documents that we
incorporate by reference includes some forward-looking statements that involve a
number of risks and uncertainties. A number of factors could cause our actual
results, performance, achievements, or industry results to be very different
from the results, performance or achievements expressed or implied by these
forward-looking statements.

     In addition, forward-looking statements depend upon assumptions, estimates
and dates that may not be correct or precise and involve known or unknown risks,
uncertainties and other factors. Accordingly, a forward-looking statement in
this report is not a prediction of future events or circumstances and those
future events or circumstances may not occur. Given these uncertainties, you are
warned not to rely on the forward-looking statements. A forward-looking
statement is usually identified by our use of certain terminology including
"believes," "expects," "may," "will," "should," "seeks," "pro forma,"
"anticipates" or "intends," or by discussions of strategies or intentions. We
are not undertaking any obligation to update these factors or to publicly
announce the results of any changes to our forward-looking statements due to
future events or developments.

                                    PART II

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 permits existing stockholders to offer for sale shares
of Class A Common Stock on predetermined days (each, a "Trade Date"). Generally,
there are four Trade Dates each year which typically occur approximately two
weeks after meetings of the Company's Board of Directors (the "Board of
Directors") which are currently scheduled for January, April, July and October.
All shares of Class B Common Stock to be sold in the Limited Market must first
be converted into 20 times as many shares of Class A Common Stock. All sales are
made at the prevailing price of the Class A Common Stock determined by the Board
of Directors pursuant to the valuation process described below. 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 may subscribe to
purchase up to a specified number of shares of Class A Common Stock. In
addition, the trustees or agents of the Company's Employee Stock Retirement Plan
("ESRP"), Cash or Deferred Arrangement ("CODA"), the 1998 Employee Stock
Purchase Plan, Stock Compensation Plan, Management Stock Compensation Plan, Key
Executive Stock Deferral Plan, the Telcordia Technologies Savings and Security
Plan and the Telcordia Technologies Savings Plan for Salaried Employees
(collectively, the "Telcordia Savings Plans") and AMSEC LLC Employees 401(k)
Profit Sharing Plan ("AMSEC 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, ESRP,
CODA, the Telcordia Savings Plans and the AMSEC Plan) pay Bull, Inc. a
commission currently equal to 2% 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, offers by stockholders to sell
2,000 or less shares of Class A Common Stock (or up to the first 2,000 shares if
more than 2,000 shares of Class A Common Stock are offered by any such
stockholder) will be accepted first. Offers to sell shares in excess of 2,000
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 2,000 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 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 year
2000, the Company purchased 2,010,309 shares in the Limited Market which
accounted for 20.4% of the total shares purchased by all buyers in the Limited
Market during fiscal year 2000. In fiscal year 1999, the Company did not
purchase any shares in the Limited Market as the number of shares offered by
stockholders did not exceed the number of shares sought to be purchased by
authorized buyers.

     During the 2000 and 1999 fiscal years, the trustees of the Company's CODA,
1998 Employee Stock Purchase Plan, the Telcordia Savings Plans and the AMSEC
Plan purchased an aggregate of 4,259,275 shares and 11,933,108 shares,
respectively, in the Limited Market. These purchases accounted for approximately
43.2% and 73.4% of the total shares purchased by all buyers in the Limited
Market during fiscal years 2000 and 1999, 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

                                       15
<PAGE>   16

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 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 on any
Trade Date 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
2000 and 1999, the Company sold an aggregate of 1,707,948 and 10,505,100 shares
of Class A Common Stock, respectively, in the Limited Market or 17.3% and 64.6%,
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.
For the periods prior to August 31, 1999, the share numbers have been restated
to reflect the 4-for-1 split of the Company's Class A Common Stock.

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

     The price of the Class A Common Stock (the "Formula Price") is established
by the Board of Directors pursuant to the valuation process which includes the
formula set forth below (the "Formula"). The Board of Directors sets the Market
Factor (as defined below) in the Formula at the value which causes the Formula
to yield the price which the Board of Directors believes represents a fair
market value. The Formula Price is the price at which the Class A Common Stock
trades in the Limited Market and 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. The Stock
Policy Committee of the Board of Directors has been authorized by the Board of
Directors to review the Formula Price during the interim period between meetings
of the Board of Directors to ensure that the Formula Price continues to
represent a fair market value. The Board of Directors or the Stock Policy
Committee may, if deemed appropriate, modify the Formula Price or recommend
postponement of a Trade Date. Pursuant to the Company's Certificate of
Incorporation, the price applicable to shares of Class B Common Stock is equal
to 20 times the Formula Price. See "Business -- Risk Factors -- Our Stock Price
is Determined by Our Board of Directors and is Not Established by Market
Forces."

     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 diluted 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 20 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 18.

     The Formula Price of the Class A Common Stock, expressed as an equation, is
as follows:

</TABLE>

     A valuation formula containing consideration of stockholder equity and
earnings per share was first used by the Board of Directors in establishing the
stock price of the Class A Common Stock in 1972. The Formula was amended in
1973, by inclusion of the Market Factor, to reflect the broad range of business,
financial and market forces that also affect the fair market value of the Class
A Common Stock. 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"). This modification was intended to ensure that the Formula Price
would be a fair market value as required by law. The Formula Price had always
exceeded the Book Value Floor, and the Book Value Floor was never used to
establish the Formula Price. The Formula was also modified by the Board of
Directors on April 10, 1998 so that the Weighted Average Shares Outstanding or
"W" was derived by reference to the Company's "diluted earnings per share"
rather than by reference to the Company's "primary earnings per share." This
modification was made to conform to changes in the accounting standards related
to the calculation of earnings per share. See "Business -- Risk Factors -- Our
Stock Price is Determined by Our Board of Directors and is Not Established by
Market Forces."

     The Board of Directors has broad discretion to modify the Formula.
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 independent directors, 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.

     In determining the price of 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, the stock price of its publicly traded investments, general
economic conditions, input from an independent appraisal firm and other factors
it deems relevant. The Board of Directors sets the Market Factor at the value
which causes the Formula to yield a price equal to the Board of Directors'
assessment of a fair market value for the Class A Common Stock. In conjunction
with the Board of Directors' valuation process, an appraisal of Class A Common
Stock is prepared by an independent appraisal firm. Valuation input from the
appraisal firm is one of the factors considered by the Board of Directors in
establishing the Formula Price. 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 Board of Directors has authorized the
Stock Policy Committee to review the Formula Price during the interim period
between meetings of the Board of Directors to ensure that the Formula Price
continues to represent a fair market value. If the Stock Policy Committee deemed
it appropriate to modify the Formula Price, it would use the same valuation
process used by the Board of Directors to determine the Formula Price. The Board
of Directors believes that the valuation process results in a value which
represents a fair market value for the Class A Common Stock within a broad range
of financial criteria.

     The value assigned by the Board of Directors to the Market Factor has been
subject to larger and more frequent changes. Nonetheless, the Board of Directors
continues to use the Formula in determining the Formula Price. The price of the
Class A Common Stock and the value of the Market Factor could be subject to
greater fluctuations in the future than in the past due to a number of factors,
including (i) the distortive impact of one-time events not in the normal course
of business on the Company's earnings used to calculate the Formula Price, such
as the gain recognized by SAIC Venture Capital, in the first quarter of the
Company's fiscal year 2001 on the sale of NSI stock in the secondary offering,
(ii) the volatility of the stock price of those publicly-traded companies in
which the Company owns stock, and its impact on the Formula Price, (iii) the
increase of the Company's commercial and international business as a proportion
of the

                                       17
<PAGE>   18

Company's overall business and the greater volatility associated with companies
in such business areas and (iv) the impact of acquisitions, investments and
joint ventures that the Company may pursue. See "Business -- Risk
Factors -- Changes in Our Business May Increase Volatility of the Stock Price."

     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. The table has been
restated to reflect the 4-for-1 stock split which became effective on August 31,
1999. The Class A Common Stock has been rounded to the nearest penny. 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
"Business -- Risk Factors -- Future Returns on Our Common Stock May Differ
Significantly from Historical Returns."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     The Company primarily provides diversified professional and technical
services involving the application of scientific expertise, together with
computer and systems technology, to solve complex technical problems for a broad
range of government and commercial customers, both in the U.S. and abroad.
Through its subsidiary, Telcordia, the Company is a global provider of software,
engineering and consulting services, advanced research and development,
technical training and other services to the telecommunications industry. The
Company completed the acquisition of Telcordia in the fourth quarter of 1998.
Consequently, the 1999 consolidated financial statements reflect the Company's
first full year of operations for Telcordia.

     The Company's subsidiary, NSI, continued to experience growth in its
business and have a positive impact on the Company's consolidated financial
position and results of operations. On February 12, 1999, NSI completed a
secondary offering of 4,580,000 shares of its Class A Common Stock. Of the
shares sold in the offering, the Company sold 4,500,000 shares at $170 per share
and received proceeds, net of underwriter's commissions, of $729,000,000 and
recognized a gain on the sale of $698,374,000. On March 23, 1999, NSI completed
a 2-for-1 split of its Class A Common Stock and Class B Common Stock. After the
stock split, the Company held 14,850,000 shares of NSI Class B Common Stock,
which were entitled to ten votes per share and represented 44.7% ownership
interest in NSI and approximately 89% of the combined voting power. On June 3,
1999, the Company converted its 14,850,000 shares of NSI Class B Common Stock
into an equal number of shares of NSI's Class A Common Stock, which are entitled
to one vote per share, thereby reducing the Company's voting power to 44.7%. As
shares of NSI Class A Common Stock are issued pursuant to NSI employee stock
compensation plans, the Company's ownership interest in NSI is diluted. As of
January 31, 2000, the Company held a 43.8% ownership in NSI which is
consolidated in the accompanying financial statements because the Company
controlled the NSI Board of Directors. Subsequent to the year ended January 31,
2000, the Company further reduced its ownership level in NSI in another
secondary offering which was completed by NSI on February 11, 2000. Of the
8,889,500 shares sold in this offering, the Company sold 6,700,000 shares, NSI
sold 2,159,500 shares and other selling stockholders sold 30,000 shares at $247
per share before deducting underwriting commissions of $9.75 per share. The
Company received net proceeds from the offering of $1,589,575,000 and will
recognize a gain on the sale before income taxes in the first quarter ending
April 30, 2000 of approximately $1,466,000,000. On February 15, 2000, NSI
announced a 2-for-1 stock split to be effective March 10, 2000. Upon completion
of this secondary offering and giving effect to the stock split, the Company
owned 16,300,000 shares of NSI Class A Common Stock, which represents a 22.6%
interest in NSI. With the recent recomposition of the NSI Board of Directors and
its current ownership interest in NSI, the Company will no longer consolidate
NSI's financial statements and will instead recognize its proportionate share of
NSI's net income or loss under the equity method of accounting beginning in the
first quarter ending April 30, 2000.

     On March 6, 2000, NSI entered into a merger agreement with VeriSign, Inc.
("VeriSign"), a publicly traded company and leading provider of Internet trust
services, pursuant to which VeriSign would acquire NSI and NSI would become a
wholly-owned subsidiary of VeriSign. Under the merger agreement, VeriSign will
issue 1.075 shares of VeriSign common stock for each share of NSI stock (after
giving effect to the 2-for-1 split of NSI common stock completed on March 10,
2000). This merger would result in the Company holding approximately 9% of
VeriSign's outstanding shares. The transaction is expected to close in the third
quarter of calendar 2000, subject to obtaining the approval of the stockholders
of VeriSign and NSI and necessary regulatory approvals.

     On April 9, 1999, the Company's Board of Directors approved a
recapitalization proposal which included an increase to the number of authorized
shares of Class A Common Stock from 100,000,000 shares to 1,000,000,000 shares
and a 4-for-1 stock split of the Company's Class A Common Stock. This
recapitalization proposal was approved by the stockholders on July 9, 1999 at
the 1999 Annual Stockholders Meeting and became effective August 31, 1999 for
stockholders of record at that date. All historical share and per share data has
been retroactively restated to reflect the stock split. The Company did not
effect a split for the Class B Common Stock but increased the relative voting
and other rights to maintain the relative rights of the Class A Common Stock and
Class B Common Stock.

     On September 3, 1999, the Company sold the stock of its TransCore business
unit and recognized a gain on the sale of $29 million which has been reflected
in other income.

RESULTS OF OPERATIONS

     Revenues increased 17%, 53% and 29% in 2000, 1999 and 1998, respectively,
over the prior year. INTESA, Telcordia and NSI were responsible for 6 percentage
points of the increase in 2000 compared to 37 and 21 percentage points in 1999
and 1998, respectively. The remaining increase in revenues of 11 percentage
points in 2000 compared to 16 and 8 percentage points in 1999 and 1998,
respectively, was attributable to growth in the Company's traditional business
areas. Revenues in 2000 from the Company's principal customer, the U.S.
Government, continued to grow and shift toward the service type contracts which
are competitively priced utilizing lower cost structures. 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 these lower cost service
type contracts.

     Revenues from the U.S. Government as a prime contractor or subcontractor
accounted for 52% of revenues in 2000, 50% in 1999 and 66% in 1998. On an
absolute basis, U.S. Government revenues increased 21% in 2000, 17% in 1999 and
7% in 1998 over the respective prior year. The increase in 2000 is primarily
attributable to faster growth in the Company's traditional business areas
through internal growth and acquisitions in the Regulated Segment compared to
the growth rate in the commercial and international business areas which was
impacted by the sale of the TransCore business unit. The decrease in revenues
from the U.S. Government as a percentage of revenues from 1998 to 1999 is
primarily 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, commercial information
technology, telecommunications and transportation business areas. On an absolute
basis, non-U.S. Government revenues increased 13% in 2000, 124% in 1999 and 109%
in 1998 over the respective prior year. The significant increase in non-U.S.
Government revenues in 1999 is primarily attributable to the inclusion of a full
year of operations for Telcordia compared to 1998, the year in which Telcordia
was acquired during the fourth quarter, and growth in INTESA and NSI revenues
over 1998.

     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 increase in revenues from firm fixed-price contracts and associated relative
decrease in revenues from cost-reimbursement contracts from 1998 to 1999 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.

     As more fully discussed in the Notes to Consolidated Financial Statements,
the Company's operating groups ("Groups") are divided into two segments,
Regulated and Non-Regulated, depending on the business

                                       21
<PAGE>   22

processes and laws affecting the operations of the Groups. Groups in the
Regulated segment provide technical services and products through contractual
arrangements as either a prime contractor or subcontractor to other contractors,
primarily for departments and agencies of the U.S. Government. Operations in the
Regulated segment are subject to specific regulatory accounting and contracting
guidelines such as "Cost Accounting Standards" and "Federal Acquisition
Regulations." Groups in the Non-Regulated segment provide technical services and
products primarily to customers in commercial markets. Generally, operations in
the Non-Regulated segment are not subject to specific regulatory or contracting
guidelines.

     Regulated segment revenues as a percentage of consolidated revenues were
59%, 58% and 74% in 2000, 1999 and 1998, respectively, and increased slightly in
2000 as a result of faster growth in the Company's traditional businesses areas
with departments and agencies of the U.S. Government and through acquisitions.
Non-Regulated segment revenues as a percentage of consolidated revenues were
40%, 42% and 25% in 2000, 1999 and 1998, respectively, and decreased in 2000 as
a result of slower growth in certain commercial and international markets and
the impact of the sale of the TransCore business unit. The decrease in revenues
as a percentage of consolidated revenues in 1999 and 1998 in the Regulated
segment reflected the faster growth in the Non-Regulated segment particularly in
the telecommunications area, as Telcordia was acquired toward the end of 1998,
and in the information technology markets. Regulated segment revenues, on an
absolute basis, increased 19% in 2000, 20% in 1999 and 8% in 1998. Non-Regulated
segment revenues, on an absolute basis, have increased 12% in 2000, 154% in 1999
and 190% in 1998. Telcordia and NSI primarily accounted for the growth in
Non-Regulated segment revenues in 2000, whereas in 1999 and 1998, Telcordia, NSI
and INTESA accounted for the growth.

     The Company's business is directly related to the receipt of contract
awards and contract performance. There were 762 contracts, which include 279 of
Telcordia's contracts, with annual revenues greater than $1 million in 2000,
compared with 685 and 440 such contracts in 1999 and 1998, respectively. These
larger contracts represented 62% of the Company's revenues in 2000 and 71% in
1999 and 1998. Of these contracts, 61 contracts had individual revenues greater
than $10 million in 2000 compared to 55 such contracts in 1999 and 39 in 1998.
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 needed 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 system integration type contracts. At the end of 2000, the Company
had 36,500 full-time employees compared to 33,000 and 30,300 at the end of 1999
and 1998, respectively. Material and subcontract ("M&S") revenues were $1,127
million in 2000, $949 million in 1999 and $755 million in 1998. As a percentage
of total revenues, M&S revenues were 20% in 2000, 20% in 1999 and 25% in 1998.
The decrease as a percentage of revenues in 1999 is primarily attributable to
Telcordia, whose revenues are generated primarily from the services of its
technical staff.

     The cost of revenues as a percentage of revenues was 77.8% in 2000, 78.8%
in 1999 and 84.9% in 1998. The decrease as a percentage of revenues in 2000
reflects generally improved operating performance and margins at Telcordia and
margin improvements at NSI related to achieving economies of scale due to the
growth of NSI's subscription-based domain name registration business. Cost of
revenues as a percentage of revenues, excluding Telcordia, INTESA and NSI, was
88.9% in 2000, 89.3% in 1999 and 88.3% in 1998.

     Selling, general and administrative expenses ("SG&A") are comprised of
general and administrative ("G&A"), bid and proposal ("B&P") and independent
research and development ("IR&D") expenses. SG&A expenses as a percentage of
revenues were 15.9%, 14.5% and 9.8% in 2000, 1999 and 1998, respectively. The
increase from 1998 to 1999 was attributable to the growth in commercial revenues
which have more of their associated costs in SG&A as opposed to cost of
revenues. SG&A costs as a percentage of revenues, excluding Telcordia, INTESA
and NSI, were 8.9%, 7.5% and 7.6% in 2000, 1999 and 1998, respectively. The
increase from 1999 to 2000 was driven by G&A costs, which as a percentage of
total revenues were 7.9% in 2000 compared to 6.8% in 1999 and 6.4% in 1998. The
increase in G&A costs was primarily attributable to increased goodwill
amortization from acquisitions completed in 2000 and the

                                       22
<PAGE>   23

impairment of goodwill and other intangible assets of $50.5 million. Of the
total amount of impairment losses taken in 2000, $42.3 million was related to a
business unit in the Non-Regulated segment, which was acquired in March 1999 and
represented less than 1% of total consolidated revenues and consolidated assets
at January 31, 2000. The factors leading the Company to assess the
recoverability of goodwill and other intangible assets of this acquisition were
greater-than-expected operating losses since the time of acquisition and the
loss of a major contract procurement. The assessment of the expected future
undiscounted cash flows indicated that an impairment existed. The impairment
loss was quantified by estimating the fair value of the business unit using the
discounted cash flow method. Marketing and B&P costs have increased to 5.9% of
revenues in 2000 compared to 5.1% in 1999 and 2.6% in 1998, primarily as a
result of higher marketing and proposal costs at Telcordia and NSI. IR&D costs
have also historically fluctuated depending on the stage of development for
various hardware and software systems and were 2.1% of revenues in 2000 compared
to 2.5% in 1999 and .8% in 1998. The decrease from 1999 to 2000 was primarily
attributable to reduced spending at Telcordia.

     Operating profit margins (operating income as a percentage of revenues) by
segment are strongly correlated to the Company's financial performance on the
contracts within each segment. The operating profit margin in the Regulated
segment was 6.3% in 2000, 5.2% in 1999 and 5.9% in 1998. The increase in
operating profit margin in the Regulated segment in 2000 compared to 1999 was
attributable to overall margin improvements without increasing discretionary
investments in the marketing and bid and proposal areas. The lower operating
profit margin in the Regulated segment in 1999 compared to 1998 was attributable
to an increase in discretionary investments made in the marketing and bid and
proposal areas. In the Non-Regulated segment, operating profit margin was 9.7%
in 2000, 10.4% in 1999 and 6.4% in 1998. This decrease in operating profit
margin in 2000 compared to 1999 was primarily attributable to greater than
expected operating losses for a business unit in the commercial information
technology business area and a business that was acquired in 2000. The increase
in operating profit margin in the Non-Regulated segment in 1999 compared to 1998
is attributable to performance in the telecommunications and information
technology business area at Telcordia, INTESA and NSI as well as operating
profit margin improvement in certain foreign subsidiaries which had losses in
1998.

     Interest expense of $27 million, $34 million and $12 million in 2000, 1999
and 1998, respectively, primarily relates to interest on the Company's
outstanding public debt securities, a building mortgage, deferred compensation
arrangements, capital lease obligations and notes payable. The decrease in
interest expense in 2000 compared to 1999 was primarily driven by a decrease in
capital lease obligations at INTESA. The increase in interest expense in 1999
was primarily driven by an increase in deferred compensation balances, capital
lease obligations and the public debt securities which were issued at the end of
1998.

     Other income, net, was $32 million in 2000 compared to an expense of $5
million in 1999 and income of $3 million in 1998. The increase in 2000 was
primarily attributable to the $29 million gain on the sale of the TransCore
business unit. The net expense in 1999 was primarily attributable to an equity
loss in an affiliate of $6 million and an other-than-temporary loss on a
marketable equity security of $3 million, both of which were partially offset by
a gain on sale of business assets of $4 million. In 1998, the net other income
was primarily attributable to gains on sales of business assets and a loss on
forward treasury lock agreements, as discussed in Note A of the Notes to
Consolidated Financial Statements.

     Minority interest in income of consolidated subsidiaries was $44 million,
$18 million and $11 million in 2000, 1999 and 1998, respectively. The increase
in 2000 was attributable to an increase in NSI net income and the Company
selling some of its shares of NSI common stock in the secondary offering on
February 12, 1999 which increased the minority interest in NSI to approximately
55% compared to a 28% minority interest in NSI in 1999. In addition, in 2000,
the Company formed another joint venture whereby the minority shareholder owns
45%. In 1999, the increase in minority interest was primarily attributable to
growth in income for NSI and INTESA, whose minority interest ownership remained
consistent from 1998. The increase in minority interest in 1998 was solely
related to the formation of INTESA and the initial public offering of NSI which
initially created a 24% minority interest. Prior to 1998, the Company did not
have any minority interest shareholders in consolidated subsidiaries.

                                       23
<PAGE>   24

     The provision for income taxes as a percentage of income before income
taxes was 41.6% in 2000, 47.7% in 1999 and 46.5% in 1998. The lower effective
tax rate in 2000 reflects the resolution of certain tax positions related to the
Company's on-going appeals process with the IRS for fiscal years 1988 through
1993. In addition, a lower tax rate on the gain on the sale of NSI common stock
contributes to reducing the overall effective tax rate. The higher effective tax
rate in 1999 compared to 1998 was primarily attributable to non-deductible
goodwill amortization and a reassessment of certain tax positions related to the
Company's on-going appeals process with the IRS for fiscal years 1988 through
1993.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's primary sources of liquidity continue to be funds provided by
operations and a five-year revolving credit facility. In addition, the proceeds
from the sale of NSI common stock in February 1999 provided an additional source
of liquidity for the Company in 2000. At January 31, 2000 and 1999, there were
no borrowings outstanding under the credit facility and cash and cash
equivalents and short-term investments totaled $1,094 million and $508 million,
respectively. Cash flows generated from operating activities were $434 million
in 2000 compared to $380 million in 1999 and $351 million in 1998.

     Cash flows spent on investing activities were $7 million in 2000 compared
to $223 million and $397 million in 1999 and 1998, respectively. Excluding the
proceeds of $729 million from the sale of NSI common stock in 2000 and $118
million from the sale of debt and equity securities, net cash flows spent on
investing activities were $854 million in 2000 compared to $223 million and $397
million in 1999 and 1998, respectively. The Company completed more acquisitions
in 2000 than in 1999, purchased debt and equity securities, made investments in
other companies, and increased expenditures for property and equipment,
primarily at NSI. In addition, proceeds from the sale of business assets
increased in 2000. The decrease in investing activities in 1999 was primarily
attributable to the types of investments and sizes of business acquisitions
completed. However, these were smaller in size compared to the acquisition of
Telcordia in 1998. In addition, in 1999, NSI utilized its cash to make
investments in debt and equity securities. Although the Company used $340
million of cash for acquisitions of certain business assets, net of cash
acquired, in 1998, the Company also received proceeds of $48 million from the
sale of certain business units and certain other business assets. The Company
intends to continue to make additional acquisitions and equity investments in
the future. Capital expenditures, excluding land and buildings, were $162
million, $85 million and $52 million in 2000, 1999 and 1998, respectively, and
are expected to be approximately $160 million for 2001. Expenditures for land
and buildings were $4 million, $3 million and $18 million in 2000, 1999 and
1998, respectively, and are expected to be approximately $11 million for 2001.

     The Company used cash of $144 million for financing activities in 2000
compared to generating cash of $43 million from financing activities in 1999 and
$191 million in 1998. In 2000, the Company did not generate as much cash from
the sales of the Company's common stock as it did in 1999 and 1998, while
repurchases of its common stock increased in 2000. In 1999, cash was primarily
generated from sales of the Company's stock and primarily used for repurchases
of common stock. In 1998, the primary sources of cash were the proceeds from
issuing public debt securities, proceeds from the initial public offering of NSI
common stock and proceeds from the sale of the Company's common stock, while the
primary use of cash was for repurchases of common stock. The increase in common
stock repurchases from 1998 through 1999 was primarily attributable to increased
repurchases of common stock from the Company's Employee Stock Retirement Plan
("ESRP") in order for the ESRP to fund payouts to participants.

     The Company's existing cash, cash equivalents, short-term investments, cash
flows from operations and borrowing capacity are expected to provide sufficient
funds for the Company's operations, common stock repurchases, capital
expenditures and future long-term debt requirements. In addition, acquisitions
and equity investments in the future are expected to be financed from
operations, borrowing capacity and from sales of the Company's common stock.

     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, is expected to have a material

                                       24

adverse effect on its consolidated financial position, results of operations,
cash flows or its ability to conduct business.

EFFECTS OF INFLATION

     The Company's cost-reimbursement type contracts are generally 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 in international markets as a result of its impact on the
Company's profitability and the pricing offered to its non-U.S. customers.

YEAR 2000

     Since 1996, the Company has been engaged in a program to prepare the
Company's centralized internal computer systems and applications for the Year
2000. The program was designed to minimize risk to the Company's consolidated
financial position, results of operations, cash flows and its ability to conduct
business. The Company has not encountered any material Year 2000 issues with its
information technology ("IT") systems, non-IT systems, critical service
suppliers and vendors, or the Company's services and products and does not
expect to incur material costs in the future related to Year 2000 related
issues.

FORWARD-LOOKING INFORMATION

     The foregoing discussion in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" contains forward-looking
statements, including statements regarding the intent, belief or current
expectations of the Company or its officers with respect to, among other things,
trends affecting the Company's financial condition or results of operation and
the impact of competition. Such statements are not guarantees of future
performance and involve risks and uncertainties, and actual results may differ
materially from those in the forward-looking statements as a result of various
factors. Some of these factors include, but are not limited to: a decrease in or
the failure to increase business with the U.S. Government, international and
commercial customers; the ability of the Company to continue to identify,
consummate and integrate additional acquisitions; the ability of the Company to
competitively price its technical services and products; the risk of early
termination of U.S. Government contracts; the risk of losses or reduced profits
on firm fixed-price contracts; a failure to obtain reimbursement for costs
incurred prior to the execution of a contract or contract modification; and
audits of the Company's costs, including allocated indirect costs, by the U.S.
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.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company is exposed to certain market risks which are inherent in the
Company's financial instruments which arise from transactions entered into in
the normal course of business. The following information about the Company's
market sensitive financial instruments contains forward-looking statements.

     Interest Rate Risk -- The Company's exposure to market risk for changes in
interest rates relates primarily to the Company's investment portfolio, short
and long-term receivables and long-term debt obligations.

     The Company primarily enters into debt obligations to support capital
expenditures, working capital needs and merger and acquisition activity.

                                       25

     Investment policies have been established to protect the safety, liquidity
and after-tax yield of invested funds. Such policies establish guidelines on
acceptable instruments in which to invest and maximum maturity dates. They also
require diversification in the investment portfolios by establishing maximum
amounts that may be invested in designated instruments. The Company does not
authorize the use of derivative financial instruments in its investment
portfolio. The Company's policy requires that all investments mature in three
years or less. Strategic investments may have characteristics that differ from
those described above.

     The table below provides information about the Company's financial
instruments that are sensitive to changes in interest rates, including debt
obligations, short-term and long-term receivables and short-term investments.
For debt obligations, short-term and long-term receivables and short-term
investments, the table presents principal cash flows in U.S. dollars and related
weighted average interest rates by expected maturity dates.

     Foreign Currency Risk -- Although the majority of the Company's
transactions are in U.S. dollars, some transactions are based in various foreign
currencies. The Company's objective in managing its exposure to foreign currency
exchange rate fluctuations is to mitigate adverse fluctuations in earnings and
cash flows

                                       26
<PAGE>   27

associated with foreign currency exchange rate fluctuations. The policy allows
for actively managing cash flows, anticipated transactions and firm commitments
through the use of natural hedges and forward foreign exchange contracts. The
principal currencies hedged as of January 31, 2000 are the French franc,
Norwegian krone, Belgian franc and the Australian dollar. The Company does not
use foreign currency derivative instruments for trading purposes.

     To perform sensitivity analysis, the Company assesses the risk of loss in
fair values from the impact of hypothetical changes in foreign currency exchange
rates on market sensitive instruments. The market values for foreign exchange
forward contracts are computed based upon spot rates in effect on January 31,
2000. The differences that result from comparing hypothetical foreign exchange
rates and actual spot rates as of January 31, 2000 are the hypothetical gains
and losses associated with foreign currency risk.

     A 10% adverse movement in levels of foreign currency exchange rates
relative to the U.S. dollar as of January 31, 2000, with all other variables
held constant, would result in a decrease in the fair values of the forward
foreign exchange contracts by approximately $1.4 million.

     Equity Price Risk -- At January 31, 2000, the quoted fair value of the
Company's publicly-traded available-for-sale equity securities was approximately
$168.8 million. The aggregate unrealized gain from these investments was $133.4
million. The market risk associated with these equity investments is the
potential loss in fair value resulting from a decrease in market prices. A 10%
decrease in market prices, with all other variables held constant, would result
in a decrease in the fair value of the equity investments of approximately $16.9
million.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

     On November 16, 1998, the Company notified PricewaterhouseCoopers LLP that
it was dismissing such firm as its independent accountants effective upon the
completion of the audit of the January 31, 1999 financial statements of the
Company. On November 17, 1998, the Company notified Deloitte & Touche LLP that
it would engage such firm as its new independent accountants for the audit of
the January 31, 2000 financial statements. The decision to change accountants
was approved by the Audit Committee of the Company's Board of Directors.

     The audit of the Company's financial statements for the year ended January
31, 1999 was completed by PricewaterhouseCoopers LLP, and on April 29, 1999, the
Company filed its Annual Report on Form 10-K with the SEC.

     During the fiscal years ended January 31, 1999 and January 31, 1998 and
through April 29, 1999, there were no disagreements with PricewaterhouseCoopers
LLP on any matter of accounting principles or practices, financial statement
disclosure or audit scope or procedure which disagreements, if not resolved to
the satisfaction of PricewaterhouseCoopers LLP, would have caused them to make
reference to the subject matter of such disagreement in their reports on the
financial statements for such years. The reports of PricewaterhouseCoopers LLP
on the financial statements for the fiscal years ended January 31, 1999 and
January 31, 1998 did not contain an adverse opinion or a disclaimer of opinion,
nor were such reports qualified or modified as to uncertainty, audit scope, or
accounting principles.

     During the fiscal years ended January 31, 1999 and January 31, 1998 and
through April 29, 1999, Deloitte & Touche LLP was not engaged as an independent
accountant to audit either the Company's financial statements or the financial
statements of any of its subsidiaries, nor had it been consulted regarding the
application of the Company's accounting principles to a specified transaction
other than those transactions occurring after February 1, 1999, or the type of
audit opinion that might be rendered on the Company's financial statements.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
Science Applications International Corporation

     We have audited the accompanying consolidated balance sheet of Science
Applications International Corporation and its subsidiaries as of January 31,
2000 and the related consolidated statements of income, stockholders' equity and
comprehensive income, and cash flows for the year then ended. 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 audit.

     We conducted our audit in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of January 31,
2000, and the results of their operations and their cash flows for the year then
ended in conformity with accounting principles generally accepted in the United
States of America.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of Science Applications International Corporation

     In our opinion, the consolidated balance sheet as of January 31, 1999 and
the related consolidated statements of income, stockholders' equity and
comprehensive income and of cash flows for each of the two years in the period
ended January 31, 1999 (appearing on pages F-4 through F-7 of this Annual Report
on Form 10-K) present fairly, in all material respects, the financial position,
results of operations and cash flows of Science Applications International
Corporation and its subsidiaries at January 31, 1999 and for each of the two
years in the period ended January 31, 1999, in conformity with generally
accepted accounting principles. In addition, in our opinion, the financial
statement schedule on page F-33 presents fairly, in all material respects, the
information set forth therein for the years ended January 31, 1999 and 1998 when
read in conjunction with the related consolidated financial statements. These
financial statements and financial statement schedule are the responsibility of
the Company's management; our responsibility is to express an opinion on these
financial statements and financial statement schedule 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. We have not
audited the consolidated financial statements of Science Applications
International Corporation for any period subsequent to January 31, 1999.

                   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- and wholly-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 20%
to 50% and over which the Company exercises significant influence are accounted
for under the equity method. Equity investments in affiliates over which the
Company does not exercise significant influence and whose securities do not have
a readily determinable fair market value as defined in Statement of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in
Debt and Equity Securities," are generally carried at cost. Outside investors'
interests in the majority-owned subsidiaries are reflected as minority interest.

     Certain of the Company's majority- and wholly-owned subsidiaries have
fiscal years ending December 31. The financial position and results of
operations of these subsidiaries are included in the Company's consolidated
financial statements for the years ended January 31. There were no material
intervening events for such subsidiaries from December 31, 1999 through January
31, 2000 which would materially affect the consolidated financial position or
results of operations.

     In 1998, the Company formed a joint venture, Informatica, Negocios y
Tecnologia, S.A. ("INTESA"), with Venezuela's national oil company, Petroleos de
Venezuela, S.A. ("PDVSA"), to provide information technology services in Latin
America. The Company consolidates its 51% majority interest in INTESA, whose
fiscal year end is December 31, in the consolidated financial statements.

     On February 12, 1999, the Company's partially-owned subsidiary Network
Solutions, Inc. ("NSI") completed a secondary offering of 4,580,000 shares of
its Class A Common Stock. Of the shares sold in the offering, the Company sold
4,500,000 shares at $170 per share and received proceeds, net of underwriter's
commissions, of $729,000,000 and recognized a gain on the sale of $698,374,000.
On March 23, 1999, NSI completed a 2-for-1 stock split of its Class A Common
Stock and Class B Common Stock. After the stock split, the Company held
14,850,000 shares of NSI Class B Common Stock, which were entitled to ten votes
per share and represented 44.7% ownership interest in NSI and approximately 89%
of the combined voting power. On June 3, 1999, the Company converted its
14,850,000 shares of NSI Class B Common Stock into an equal number of shares of
NSI's Class A Common Stock, which are entitled to one vote per share, thereby
reducing the Company's voting power to 44.7%. As shares of NSI Class A Common
Stock are issued pursuant to NSI employee stock compensation plans, the
Company's ownership interest in NSI is diluted. As of January 31, 2000, the
Company held a 43.8% ownership in NSI which is consolidated in the accompanying
financial statements because the Company controlled the NSI Board of Directors.
Subsequent to the year ended January 31, 2000, the Company further reduced its
ownership level in NSI in another secondary offering (Note R).

  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, which include cash and cash equivalents, short-term
investments, equity securities, long-term receivables,

                                       F-8
<PAGE>   41
                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

long-term investments and long-term debt, are reasonable estimates of their
related fair values. The carrying amount of cash and cash equivalents and
short-term investments approximates fair value because of the short maturity of
those instruments. The fair value of equity securities is based upon quoted
market prices. The fair value of long-term receivables is estimated by
discounting the expected future cash flows at interest rates commensurate with
the creditworthiness of customers and other third parties. The fair value of
long-term debt is estimated based on quoted market prices for similar
instruments and current rates offered to the Company for similar debt with the
same remaining maturities.

  Contract revenues

     The Company's revenues result from contract services performed for
commercial customers and 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 these 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. The Company
also derives revenues from software license fees, maintenance contracts and
registration services. Software license fees are generally recognized when the
software has been accepted and there are no significant obligations remaining.
Revenues from maintenance contracts are recognized over the term of the
respective contracts as maintenance services are provided. Revenues from
registration services are recognized on a straight-line basis over the life of
the registration term. Amounts billed but not yet recognized as revenue under
certain types of contracts are deferred in the accompanying consolidated balance
sheet. 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 on U.S.
Government contracts, 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 1999. Contract revenues on U.S. Government contracts have been recorded
in amounts that are expected to be realized upon final settlement.

  Cash and cash equivalents

     Cash equivalents are highly liquid investments purchased with an original
maturity of three months or less. Cash and cash equivalents at January 31, 2000
and 1999 include $583,917,000 and $371,626,000, respectively, invested in
commercial paper, institutional money market funds and time deposits.

  Investments in debt and equity securities

     Management determines the appropriate classification of its investments in
debt and equity securities at the time of purchase and reevaluates such
determination at each balance sheet date. Debt and equity securities are
classified as either available-for-sale or held-to-maturity and reflected as
short-term and long-term investments. Available-for-sale securities are carried
at market value and held-to-maturity debt securities are carried at amortized
cost. The difference between cost and market value, net of related tax effects,
is recorded in the "accumulated other comprehensive income" component of
stockholders' equity. Realized gains and losses on the sale of
available-for-sale securities are determined using the adjusted cost of the
specific securities sold.

  Restricted cash

     The Company 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
                                       F-9
<PAGE>   42
                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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.
Additionally, as discussed in Note I, cash collected from PDVSA for the INTESA
pension plan and postretirement benefit obligations is restricted as it relates
to funding of the future obligations.

  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 the shorter of the lease term or 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.

     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 and the carrying amount of the asset exceeds
the expected future undiscounted cash flows. When the carrying amount of the
asset exceeds the expected future undiscounted cash flows, an impairment loss is
recognized to reduce the assets carrying amount to its estimated fair value
based on the present value of the estimated expected future cash flows.

  Goodwill and other intangible assets

     Goodwill represents the excess of the purchase cost over the fair value of
net identifiable assets acquired in an acquisition. Goodwill and other
identifiable intangible assets are amortized on a straight line basis over three
to fifteen years. Amortization of goodwill amounted to $62,864,000, $25,139,000
and $15,403,000 in 2000, 1999 and 1998, respectively. Accumulated goodwill
amortization was $55,208,000 and $41,720,000 at January 31, 2000 and 1999,
respectively. Amortization of other intangible assets amounted to $28,731,000,
$15,508,000 and $1,250,000 in 2000, 1999 and 1998, respectively. Accumulated
other intangible assets amortization was $34,089,000 and $17,921,000 at January
31, 2000 and 1999, respectively.

     In 2000, 1999 and 1998, the Company recognized impairment losses of
$50,518,000, $13,378,000 and $2,878,000, respectively, which were included in
selling, general and administrative expense. Of the total amount of impairment
losses taken in 2000, $42,300,000 was related to a business unit in the
Non-Regulated segment, which was acquired in March 1999 and represented less
than 1% of total consolidated revenues and consolidated assets at January 31,
2000. The factors leading the Company to assess the recoverability were
greater-than-expected operating losses since the time of acquisition and the
loss of a major contract procurement. The assessment of the expected future
undiscounted cash flows indicated that an impairment existed. The impairment
loss was quantified by estimating the fair value of the business unit using the
discounted cash flow method.

                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  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

     As permitted under SFAS No. 123, "Accounting for Stock-Based Compensation,"
the Company accounts for employee 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 employee 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. 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, are presented in Note M.

  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. A general public market for the Company's common stock does not
exist. Quarterly determinations of the price of the common stock are made by the
Board of Directors pursuant to a valuation process which includes a stock price
formula. Valuation input from an independent appraisal firm is one of the
factors considered by the Board of Directors in establishing the stock price.
The Board of Directors believes that the valuation process results in a value
which represents a fair market value for the Class A Common Stock within a broad
range of financial criteria. The Board of Directors reserves the right to alter
the formula and valuation process.

     Basic earnings per share ("EPS") is computed by dividing income available
to common stockholders by the weighted average number of shares of common stock
outstanding. Diluted EPS is computed similar to basic EPS except that the
weighted average number of shares of common stock outstanding is increased to
include the effect of stock options and other stock awards granted to employees
under stock-based compensation plans that were outstanding during the period.

     On April 9, 1999, the Company's Board of Directors approved a
recapitalization proposal which included an increase to the number of authorized
shares of Class A Common Stock from 100,000,000 shares to 1,000,000,000 shares
and a 4-for-1 stock split of the Company's Class A Common Stock. This
recapitalization proposal was approved by the stockholders on July 9, 1999 at
the 1999 Annual Stockholders Meeting and became effective August 31, 1999 for
stockholders of record at that date. Stockholders' equity has been retroactively
restated to reflect the stock split for all periods presented by reclassifying
the par value of the additional shares arising from the split from additional
paid-in-capital to common stock. All share and per share data in the
accompanying Financial Statements and Notes to Consolidated Financial Statements
have been retroactively restated to reflect the stock split for all periods
presented.

  Derivative 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

                                      F-11
<PAGE>   44
                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

the settlement of the underlying transaction. At January 31, 2000, the Company
had approximately $17,644,000 of foreign currency forward exchange contracts in
British pounds, French francs, Japanese yen, Irish punts, Norwegian krones,
German deutschmarks, Hong Kong dollars, Euros, Belgian francs and Australian
dollars outstanding with net deferred gains of $648,000.

     In 1997, the Company entered into forward treasury lock agreements for a
total of $200,000,000. Such agreements were entered into to manage exposure to
fluctuations in interest rates on an anticipated, probable issuance of debt that
was to be used to finance the acquisition of Telcordia Technologies, Inc.
("Telcordia") (formerly Bellcore). The agreements terminated in 1998 resulting
in losses. Due to changes in market conditions, an unexpected decline in
interest rates and availability of cash, in 1998, the Company only issued ten
year fixed rate notes with a principal amount of $100,000,000. Therefore, a loss
of $9,047,000 was recorded as other expense upon termination of the agreement
and a loss of $9,356,000 was deferred, included in long-term debt and is being
amortized to interest expense over the life of the fixed rate notes (Note K and
Note P).

  Concentration of credit risk

     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents, accounts
receivable, short-term and long-term investments, foreign currency forward
exchange contracts and long-term receivables.

     The Company invests its available cash principally in U.S. Government and
agency securities, corporate obligations, asset and mortgage-backed securities,
municipal debt, equity 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 principal customers are the Regional Bell Operating
Companies ("RBOCs"), various agencies of the U.S. Government and commercial
customers engaged in work for the U.S. Government. The credit risk with the U.S.
Government is limited and the financial strength of the RBOCs limits the risk on
those receivables.

  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 accumulated other comprehensive income
in stockholders' equity. The functional currency of the Company's foreign
subsidiary that operates in a highly inflationary economy (INTESA) is the U.S.
dollar. The monetary assets and liabilities of this foreign subsidiary are
translated into U.S. dollars at the exchange rate in effect at the balance sheet
date. Revenues, expenses, gains and losses are translated at the average
exchange rate for the period, and non-monetary assets and liabilities are
translated at historical rates. Resulting remeasurement gains or losses of this
foreign subsidiary are recognized in the consolidated results of operations.

  Comprehensive income

     In 1999, the Company adopted SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and displaying comprehensive
income and its components. The adoption did not have an effect on net income or
total stockholders' equity. SFAS No. 130 requires unrealized gains or losses on
the Company's available-for-sale securities and foreign currency translation
adjustments to be included in other

                                      F-12

comprehensive income. 1998 financial statements have been reclassified to
conform to these requirements. The components of other comprehensive income

  Recently issued accounting pronouncements

     In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities-Deferral of the
Effective Date of FASB Statement No. 133," which defers the effective date of
SFAS No. 133 to all fiscal quarters of fiscal years beginning after June 15,
2000. Therefore, the Company will adopt SFAS No. 133 effective for the first
quarter ending April 30, 2001. SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," establishes accounting and reporting
standards for derivative instruments and for hedging activities. It requires an
entity to recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
SFAS No. 133 also requires that changes in the derivative instrument's fair
value be recognized currently in results of operations unless specific hedge
accounting criteria are met. Based on the types of derivative instruments the
Company currently has, the Company does not expect the adoption of SFAS No. 133
to have a material impact on the Company's consolidated financial position or
results of operations.

  Gains on issuance of stock by subsidiary

     Gains on issuances of unissued shares of stock by a subsidiary are
reflected as equity transactions and recorded directly to additional paid-in
capital.

     In 1998, the Company and its subsidiary NSI completed an initial public
offering of 3,795,000 shares of NSI Class A Common Stock. The initial offering
price was $18 per share with net proceeds to the Company of $63,528,000
resulting in a gain of $60,664,000 which was recorded as additional paid-in
capital.

  Reclassifications

     Certain amounts from previous years have been reclassified in the
consolidated financial statements to conform to the 2000 presentation.

NOTE B -- ACQUISITIONS AND INVESTMENTS IN AFFILIATES:

     The carrying value of the Company's equity and cost method investments was
$74,349,000 and $41,279,000 at January 31, 2000 and 1999, respectively, which
includes the unamortized excess of the Company's equity investments over its
equity in the underlying net assets of $9,211,000 and $9,718,000, respectively.

     In 2000, the Company completed acquisitions of certain business assets and
companies, which individually are not considered significant business
combinations, for an aggregate purchase price of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

approximately $302,411,000. In some cases, the Company acquired all the issued
and outstanding common stock of certain companies while in other cases, the
Company acquired certain specific assets and liabilities. All these acquisitions
have been accounted for under the purchase method of accounting and the
operations of the companies acquired have been included in the accompanying
consolidated financial statements from their respective dates of acquisition.
The aggregate purchase price was allocated to the assets acquired and
liabilities assumed based upon their estimated fair values. The aggregate excess
of the purchase price over fair value of the net tangible assets acquired of
approximately $158,494,000 has been allocated to other identifiable intangible
assets and goodwill, which will be amortized on a straight-line basis over
periods of three to ten years. Certain of the acquisitions completed have been
recorded based on preliminary purchase price pending final negotiations and
valuation. The Company does not anticipate a material change to the aggregate
purchase price or assets acquired and liabilities assumed.

     The following unaudited pro forma summary information presents the
consolidated results of operations as if the acquisitions, in aggregate, had
been completed at the beginning of the periods presented and are not necessarily
indicative of the results of operations of the consolidated Company that might
have occurred had the acquisitions been completed at the beginning of the
periods specified, nor are they necessarily indicative of future operating
results.

NOTE C -- BUSINESS SEGMENT INFORMATION:

     The Company primarily provides diversified professional and technical
services involving the application of scientific expertise, together with
computer and systems technology, to solve complex technical problems for a broad
range of government and commercial customers, both in the U.S. and abroad.
Technical services consist of basic and applied research services; design and
development of computer software; systems integration; systems engineering;
technical operational and management support services; environmental
engineering; design and integration of network systems; technical engineering
and consulting support services; and development of systems, policies, concepts
and programs. Through its subsidiary, Telcordia, the Company is a global
provider of software, engineering and consulting services, advanced research and
development, technical training and other services to the telecommunications
industry. In addition to providing technical services, the Company designs and
develops high-technology products. These products include customized and
standard hardware and software, such as automatic equipment identification
technology, sensors and nondestructive imaging instruments. Product revenues
represented 1%, 1% and 2% of consolidated revenues in 2000, 1999 and 1998,
respectively.

     The implementation of SFAS No. 131 results in the use of a management
approach in identifying segments of an enterprise. The management approach is
based on the way management organizes the operating segments within the Company
for making decisions and assessing performance. However, the Company's marketing
approach focuses on key vertical markets such as "National Security," "Health
Care," "Environment," "Energy," "Telecommunications," "Information Technology"
and "Other," which includes the Company's transportation, logistics, space and
utilities business areas and information technology support to federal civil
agencies. Marketing decisions based on these key vertical markets are made at
the lowest operational level.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company's operating groups ("Groups"), on which performance is
assessed, aggregate into two reportable segments, Regulated and Non-Regulated,
depending on the business processes and laws affecting the operations of the
Group. Groups in the Regulated segment provide technical services and products
through contractual arrangements as either a prime contractor or subcontractor
to other contractors, primarily for departments and agencies of the U.S.
Government. Operations in the Regulated segment are subject to specific
regulatory accounting and contracting guidelines such as Cost Accounting
Standards and Federal Acquisition Regulations. Groups in the Non-Regulated
segment provide technical services and products primarily to customers in
commercial markets. Generally, operations in the Non-Regulated segment are not
subject to specific regulatory accounting or contracting guidelines. Groups and
entities that do not provide technical services, which includes the Company's
Corporate Offices, are not aggregated into these reportable segments.

     The Company evaluates performance and allocates resources based on income
or loss from operations before tax. Asset information is not a component of the
Company's evaluation of the Groups. However, the Company allocates an internal
interest charge or credit ("Cost of Capital") to each Group based on an internal
formula which utilizes certain identifiable asset data in calculating the Cost
of Capital. Interest expense, as reported in the consolidated financial
statements, is generally recorded at the corporate level. In addition, the
Company does monitor capital expenditures by Groups.

     The accounting policies of the reportable segments are the same as those
described in Note A. General corporate expense allocations are reflected in the
segment operating results because all such expenses are allocated to individual
cost objectives by the Company, as required by Government Cost Accounting
Standards. Certain adjustments made at the consolidated level are not allocated
to the Groups for internal reporting purposes. Because of the nature of the
Company's business, sales between segments are not material and are recorded at
cost.

contractual maturities of one year or less, $187,238,000 of short-term debt
securities have contractual maturities of two to five years, and $49,039,000 of
short-term debt securities have contractual maturities greater than five years.
Actual maturities may differ from contractual maturities as a result of the
Company's intent to sell these securities prior to maturity date and as a result
of features of the securities that enable either the Company, the issuer, or
both to redeem these securities in part or in full at an earlier date. The
majority of the equity securities are classified as other assets in the
accompanying balance sheet.

     Held-to-maturity debt securities are investments in high rated corporate
bonds with amortized costs of $9,350,000, at January 31, 1999, which
approximates market value. There were no held-to-maturity debt securities at
January 31, 2000.

     Gross realized gains and losses of debt and equity securities were
$4,308,000 and $2,362,000, respectively, for the year ended January 31, 2000.
There were no realized gains or losses from available-for-sale securities for
the years ended January 31, 1999 and 1998.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Unbilled receivables at January 31, 2000 and 1999 include $26,655,000 and
$20,980,000, 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. 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 G -- REVOLVING CREDIT FACILITY:

     The Company has a five-year reducing revolving credit facility ("Credit
Facility") with a group of financial institutions which allow borrowings until
August 2002 and which was reduced to $675,000,000 in 2000 according to the
original terms. Borrowings under the Credit Facility are unsecured and bear
interest, at the Company's option, at various rates based on the base rate, bid
rate or on margins over the CD rate or LIBOR. The Company pays a facility fee on
the total commitment amount. Certain financial covenants required by the Credit
Facility, such as requiring the Company to maintain certain levels of net worth
and an interest coverage ratio, as well as limitation on indebtedness, have been
maintained as of January 31, 2000.

     There was no balance outstanding under the Credit Facility at January 31,
2000 and 1999. As of January 31, 2000, the entire $675,000,000 was available
under the most restrictive debt covenants of the Credit Facility and during 2000
and 1999, the Company did not borrow under the Credit Facility. In 1998, the
maximum and average amount outstanding was $320,000,000 and $38,228,000,
respectively. The weighted average interest rate in 1998 was 6.0% based upon
average daily balances.

NOTE H -- EMPLOYEE BENEFIT PLANS:

     The Company has 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 $36,617,000, $23,122,000 and $18,929,000
for 2000, 1999 and 1998, respectively.

     The Company has an Employee Stock Retirement Plan ("ESRP"), formerly known
as the Employee Stock Ownership Plan, in which eligible employees participate.
Cash or stock contributions to the ESRP 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 the amount of cash contributed
in the year of contribution. The vesting requirements for the ESRP are the same
as the PSRP. Shares of Company common stock distributed from the ESRP 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, 2000, the ESRP held
60,829,216 shares of Class A Common Stock and 24,887 shares of Class B Common
Stock with a combined fair value of $1,589,594,700. Contributions charged to
income under the Plan were $16,258,000, $25,820,000 and $22,072,000 for 2000,
1999 and 1998, 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 charged to income were $19,400,000,
$15,829,000 and $14,454,000 for 2000, 1999 and 1998, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In connection with the acquisition of Telcordia, the Company also sponsors
two contributory savings plans which allow eligible Telcordia employees to defer
a portion of their pre-tax income through contributions and contribute a portion
of their income on an after-tax basis. Such deferrals are fully vested, are not
taxable to the participant until distributed upon termination, retirement,
permanent disability or death and may be matched by the Company. The Company's
matching contributions charged to income were $18,555,000, $17,200,000 and
$2,800,000 for 2000, 1999 and 1998, respectively.

     The Company has two principal bonus compensation plans, the Bonus
Compensation Plan and the Annual Incentive Plan ("AIP"), which provide for
bonuses to reward outstanding performance. The AIP was assumed in connection
with the acquisition of Telcordia in 1998. 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 vest at the rate of 20%,
20%, 20% and 40% after one, two, three and four years, respectively. The amounts
charged to income under these plans were $140,618,000, $120,373,000 and
$49,587,000 for 2000, 1999 and 1998, respectively.

     The Company has a Stock Compensation Plan and 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 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 which is included in stockholders' equity. The unearned amounts are
amortized to expense over the vesting period. The amounts charged to income
under these plans were $3,602,000, $2,606,000 and $1,688,000 for 2000, 1999 and
1998, respectively.

     The Company also has an Employee Stock Purchase Plan ("ESPP") which allows
eligible employees to purchase shares of the Company's Class A Common Stock, at
a discount of 10% of the existing fair market value. There are no charges to
income under this plan because such plan is a non-compensatory plan. However,
the proforma effect on net income and earnings per share of compensation expense
under SFAS No. 123, "Accounting for Stock-Based Compensation" has been disclosed
in Note M.

     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 (7.95% in 2000). Deferred balances will
generally be paid upon the later of the attainment of age 65, ten years of plan
participation or retirement, unless participants obtain approval for 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.

NOTE I -- PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS:

     In connection with the acquisition of Telcordia in 1998, the Company
assumed assets and liabilities related to five noncontributory defined benefit
pension plans covering eligible management and support staff employees of
Telcordia and assumed assets and liabilities for postretirement health and life
insurance benefits for retired U.S. employees and their dependents. The Company

     For measurement purposes, a 7.0% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 2000. The rate was assumed
to decrease gradually to 5% for 2004 and remain at that level thereafter.

     The Company sponsors five noncontributory defined benefit pension plans.
Two of these plans are funded qualified plans, the Management Pension Plan and
the Support Staff Pension Plan. Benefits are based on a stated percentage of
final average pay formula for the management plans and a flat-dollar amount per
years of service for the Support Staff Pension Plan. All of the assets of the
qualified plans, which are primarily equities (international and domestic) and
fixed income securities are held in a master trust administered by the Company.
The Company's policy is to fund the "Qualified" plans based on legal
requirements, tax considerations and investment opportunities. The Company
utilizes a hybrid method for amortizing investment gains and losses. This method
fully recognizes gains and losses for fixed income securities and amortizes
gains and losses on all other asset classes over three years.

     The Company sponsors three unfunded non-qualified benefit plans for certain
members of management. One of these plans provides benefits that replace
benefits not available in the qualified plans due to design or legal
limitations. The other two plans offer additional pension benefits to certain
employees based on job level. The projected benefit obligation and accumulated
benefit obligation of these plans, which had accumulated benefit obligations in
excess of plan assets, were $14,315,000 and $9,321,000, respectively, as of
December 31, 1999, the plans' year end, and $13,397,000 and $6,337,000,
respectively, as of December 31, 1998. The non-qualified plans are unfunded and
therefore have no assets.

     The Company offers certain postretirement medical and life insurance
benefits to substantially all retired employees. Currently, the plan assets for
the life insurance benefits are held in a Voluntary Employee Benefit Association
(VEBA) trust. During 2000, the medical benefits VEBA has been depleted and
medical benefits for the retirees are being paid from Corporate assets.
Telcordia did not make any contributions to the VEBA trust during the year. The
Company's funding policy is to contribute annually an amount determined by
management, based on federal income tax limitations.

     Assumed health care cost trend rates have a significant effect on the
amounts reported for the health care plan. A one-percentage-point change in the
assumed health care cost trend rates would have the following effects:

     In 1998, when the Company formed the INTESA joint venture with PDVSA,
approximately 1,500 employees transferred from PDVSA to INTESA. Under Venezuelan
law, INTESA assumed the existing employee benefit plans, including a defined
benefit pension plan. Under the terms of the joint venture

agreement, PDVSA agreed to fund the projected benefit obligation of the pension
plan and accumulated post-retirement benefit obligation of the post-retirement
benefit plans over ten years. The obligation of PDVSA to fund these benefits has
been reflected as a related party receivable and included in other assets in the
Company's consolidated balance sheet. In addition, effective January 1, 2002
employees hired on and after January 1, 1997 will be covered by INTESA pension
plan and post-retirement medical and life benefits. The employees will receive
credit for service with INTESA rendered prior to January 1, 2002. The related
benefit obligation and unrecognized prior service cost for these employees is
reflected in the following disclosure. The plans are accounted for in accordance
with the requirements of SFAS No. 87 and SFAS No. 106.

     Benefits are based upon years of service and compensation during the twelve
months of accredited service earned immediately before retirement. The majority
of the assets of the pension plan, receivables and cash, are not currently held
in a trust. PDVSA had initially agreed to fund this obligation by December 31,
2006. Per the terms of an amended agreement, PDVSA will fund this obligation by
January 31, 2007 either through direct payments to INTESA or direct
contributions to a trust.

     In addition to the pension benefits described above, certain postretirement
benefits were also transferred to INTESA for health and life insurance benefits
for the PDVSA employees who transferred to INTESA. Eligibility for the plans and
participant cost sharing is dependent upon the participant's age at retirement,
years of service and retirement date. The Company accounts for these benefit
plans in accordance with SFAS No. 106. The accrued postretirement benefits
liability was $2,244,000 and $2,125,000 as of January 31, 2000 and 1999,
respectively. Net postretirement benefits expense was $444,000 and $329,000 for

     In January 1998, the Company issued $100,000,000 of 6.75% notes ("6.75%
Notes") under a shelf registration statement filed with the Securities and
Exchange Commission. The 6.75% Notes are due February 1, 2008 with interest
payable semi-annually beginning August 1, 1998 and were issued with a nominal
discount. The Company used the proceeds to repay certain short-term
indebtedness, including obligations assumed in connection with the acquisition
of Telcordia and for general corporate purposes. The Company amortizes the note
discount, underwriter's fees and commissions and the loss on the forward
treasury lock agreement (Note A) to interest expense which results in an
effective interest rate of 8.3% over the term of the 6.75% Notes. The Company is
subject to certain restrictions such as limitations on liens, on sale and
leaseback transactions and on consolidation, merger, and sale of assets. As of
January 31, 2000, the Company was in compliance with the restrictions.

     During 1997, the Company assumed a $6,919,000 mortgage note in connection
with the purchase of land and a building. Terms of the note include quarterly
payments of principal and interest until December 2016. Interest is adjusted
annually and was 6.4% in 2000. Additionally, the Company has various other notes
payable with interest rates from 6.0% to 9.3% that are due over the next ten
years.

     Maturities of long-term debt, excluding capital lease obligations, are as
follows:

the 1992 Stock Option Plan ("1992 Plan"). Under the 1999 Plan, 1998 Plan, 1995
Plan and 1992 Plan, 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 under these plans generally become exercisable 20%, 20%, 20%, and 40%
after one, two, three and four years, respectively. No options were granted
under the 1992 Plan after July 31, 1995, the date the 1992 Plan terminated nor
were any options granted under the 1995 Plan after July 31, 1998, the date the
1995 Plan terminated.

     If the Company had elected to recognize compensation expense based upon the
fair value at the grant dates for stock option awards granted in 2000, 1999 and
1998 and for shares issued under the ESPP in 2000, 1999 and 1998, consistent
with the methodology prescribed by SFAS No. 123, net income in 2000, 1999 and
1998 would have been reduced by $22,009,000, $14,958,000 and $10,328,000,
respectively. Basic earnings per share would have been reduced by $.09, $.07,
and $.05 per share in 2000, 1999 and 1998, respectively, and diluted earnings
per share would have been reduced by $.06 per share in 2000 and 1999 and $.04
per share in 1998. These amounts were determined using weighted-average per
share fair values of options granted in 2000, 1999 and 1998 of $4.24, $2.78 and
$1.97, 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 2000, 1999 and 1998: no dividend yield, no volatility, risk free
interest rates ranging from 4.6% to 6.8% 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.

     A summary of changes in outstanding options under the plans during the
three years ended January 31, 2000, is as follows:

NOTE N -- LEASES:

     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 operating leases. Rental expenses for facilities and
equipment totaled $143,196,000, $113,320,000 and $90,012,000 in 2000, 1999 and
1998, respectively.

     The Company has a seven year operating lease for a general purpose office
building, with an option to purchase the building at the end of the initial
seven year term. If the purchase option is not exercised, the Company may be
required to pay certain supplemental rental payments if proceeds from the sale
of the building to an unrelated buyer are below specified amounts. The maximum
supplemental rental payment which could be required is $28,809,000. In 1999, the
Company entered into an operating lease for land and general purpose office
facilities with an initial term of five and one-half years and an option for the
Company to purchase the property. If the purchase option is not exercised, the
Company may be required to pay certain supplemental rental payments if proceeds
from the sale of the property to an unrelated buyer are below specified amounts.
The maximum supplemental rental payment which could be required is $43,040,000.

     Assets acquired under capital leases and included in property and
equipment, and land and buildings consist of the following:

     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, is expected to have a material adverse effect on its
consolidated financial position, results of operations, cash flows or its
ability to conduct business.

NOTE Q -- SALE OF BUSINESS:

     On September 3, 1999, the Company sold the stock of its TransCore business
unit and recognized a gain on the sale of $28,847,000. The gain is reflected in
other income in the accompanying consolidated financial statements.

NOTE R -- SUBSEQUENT EVENT:

     On February 11, 2000, NSI completed a secondary offering of 8,889,500
shares of its Class A Common Stock. Of the shares sold in the offering, the
Company sold 6,700,000 shares, NSI sold 2,159,500 shares and other selling
stockholders sold 30,000 shares at $247 per share before deducting underwriting
commissions of $9.75 per share. The Company received net proceeds from the
offering of $1,589,575,000 and will recognize a gain on the sale before income
taxes in the first quarter ending April 30, 2000 of approximately
$1,466,000,000. On February 15, 2000, NSI announced a 2-for-1 stock split to be
effective March 10, 2000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Upon completion of this secondary offering and giving effect to the stock split,
the Company owned 16,300,000 shares of NSI Class A Common Stock which represents
a 22.6% interest in NSI. With the recent recomposition of the NSI Board of
Directors and the current ownership interest in NSI, the Company will no longer
consolidate NSI's financial statements and will instead recognize its
proportionate share of NSI's net income or loss under the equity method of
accounting beginning in the first quarter ending April 30, 2000.

     On March 6, 2000, NSI entered into a merger agreement with VeriSign, Inc.
("VeriSign"), a publicly traded company and leading provider of Internet trust
services, pursuant to which VeriSign would acquire NSI and NSI would become a
wholly-owned subsidiary of VeriSign. Under the merger agreement, VeriSign will
issue 1.075 shares of VeriSign common stock for each share of NSI stock (after
giving effect to the 2-for-1 split of NSI common stock completed on March 10,
2000). This merger would result in the Company holding approximately 9% of
VeriSign's outstanding shares. The transaction is expected to close in the third
quarter of calendar 2000, subject to obtaining the approval of the stockholders
of VeriSign and NSI and necessary regulatory approvals.

                 SCIENCE APPLICATIONS INTERNATIONAL CORPORATION
                            (A DELAWARE CORPORATION)


                                    ARTICLE I
                                     OFFICES

        Section 1.01 REGISTERED OFFICE. The registered office of SCIENCE
APPLICATIONS INTERNATIONAL CORPORATION (the "Corporation") in the State of
Delaware shall be at 1209 Orange Street, City of Wilmington, County of New
Castle, and the name of the registered agent in charge thereof shall be The
Corporation Trust Company.

        Section 1.02 PRINCIPAL OFFICE. The principal office for the transaction
of the business of the Corporation shall be at 10260 Campus Point Drive, San
Diego, California 92121. The Board of Directors (the "Board") is hereby granted
full power and authority to change said principal office from one location to
another.

        Section 1.03 OTHER OFFICES. The Corporation may also have an office or
offices at such other place or places, either within or without the State of
Delaware, as the Board may from time to time determine or as the business of the
Corporation may require.


                                   ARTICLE II
                            MEETINGS OF STOCKHOLDERS

        Section 2.01 ANNUAL MEETINGS. An annual meeting of stockholders shall be
held for the election of directors and to transact such other business as may
properly be brought before the meeting.

        Section 2.02 SPECIAL MEETINGS. Special meetings of the stockholders of
the Corporation for any purpose or purposes may be called at any time by the
Board, or by a committee of the Board which has been duly designated by the
Board and whose powers and authority, as provided in a resolution of the Board
or in the Bylaws, include the power to call such meetings, but such special
meetings may not be called by any other person or persons; provided, however,
that if and to the extent that any special meeting of stockholders may be called
by any other person or persons specified in any provisions of the Certificate of
Incorporation or any amendment thereto or any certificate filed under Section
151(g) of the Delaware General Corporation Law (or its successor statute as in
effect from time to time hereafter), then such special meeting may also be
called by the person or persons, in the manner, at the times and for the
purposes so specified.

        Section 2.03 TIME AND PLACE OF MEETINGS. All meetings of the
stockholders shall be held at such places, within or without the State of
Delaware, on such date and at such time as may from time to time be designated
by the person or persons calling the respective meeting and specified in the
respective notices or waivers of notice thereof.

        Section 2.04 NOTICE OF MEETINGS AND ADJOURNED MEETINGS; WAIVERS OF
Notice.

        (a) Whenever stockholders are required or permitted to take any action
at a meeting, a written notice of the meeting shall be given to each stockholder
of record entitled to vote at such meeting which shall state the place, date and
hour of the meeting, and, in the case of a special meeting, the purpose or
purposes for which the meeting is called. Notice may be given by such delivery
means (mail, telecopy, electronic or other) as the Secretary deems appropriate
and in compliance with applicable law and shall be delivered to the
stockholders' address as it appears on the stock transfer records of the
Corporation. Unless otherwise required by Delaware Law, such notice shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder of record entitled to vote at such meeting. Unless otherwise
expressly required by Delaware Law, when a meeting is adjourned to another time
or place (whether or not a quorum is present), notice need not be given of the
adjourned meeting if the time and place thereof are announced at the meeting at
which the adjournment is taken. At the adjourned meeting, the Corporation may
transact any business which might have been transacted at the original meeting.
If the adjournment is for more than 30 days, or after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

        (b) A written waiver of any such notice signed by the person entitled
thereto, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends the meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Business transacted at any special meeting of stockholders shall be
limited to the purposes stated in the notice.

        Section 2.05 QUORUM. Except as provided by Delaware Law, the holders of
record of a majority in voting interest of the shares of stock of the
Corporation entitled to be voted thereat, present in person or by proxy, shall
constitute a quorum for the transaction of business at any meeting of the
stockholders of the Corporation or any adjournment thereof. In the absence of a
quorum at any meeting or any adjournment thereof, a majority in voting interest
of the stockholders present in person or by proxy and entitled to vote thereat
or, in the absence therefrom of all the stockholders, any officer entitled to
preside at, or to act as a secretary of, such meeting may adjourn such meeting
from time to time. At any such adjourned meeting at which a quorum is present,
any business may be transacted which might have been transacted at the meeting
as originally called.

        Section 2.06 VOTING.

        (a) At each meeting of the stockholders, each stockholder shall be
entitled to vote, in person or by proxy, each share or fractional share of the
stock of the Corporation having voting rights on the matter in question and
which shall have been held by such stockholder and registered in such
stockholder's name on the books of the Corporation:

               (i) on the date fixed pursuant to Section 6.05 of these Bylaws as
        the record date for the determination of stockholders entitled to notice
        of and to vote at such meeting, or


                                       2
<PAGE>   6

               (ii) if no such record date shall have been so fixed, then (a) at
        the close of business on the day before the day on which notice of the
        meeting shall be given or (b) if notice of the meeting shall be waived,
        at the close of business on the day before the day on which the meeting
        shall be held.

        (b) Shares of its own stock belonging to the Corporation or to another
corporation, if a majority of the shares entitled to vote in the election of
directors in such other corporation is held, directly or indirectly, by the
Corporation, shall neither be entitled to vote nor be counted for quorum
purposes.

        (c) Any such voting rights may be exercised by the stockholder entitled
thereto in person or by his or her proxy appointed by an instrument in writing,
subscribed by such stockholder or by such stockholder's attorney thereunto
authorized and delivered to the secretary of the meeting; provided, however,
that no proxy shall be voted or acted upon after three (3) years from its date
unless said proxy shall provide for a longer period. At any meeting of the
stockholders all matters, except as otherwise provided in the Certificate of
Incorporation, in these Bylaws or by Delaware Law, shall be decided by the vote
of a majority in voting interest of the stockholders present in person or by
proxy and entitled to vote thereat and thereon, a quorum being present. The vote
at any meeting of the stockholders on any question need not be by ballot, except
as otherwise provided in the Certificate of Incorporation or unless so directed
by the chairman of the meeting. On a vote by ballot, each ballot shall be signed
by the stockholder voting, or by his or her proxy, if there be such proxy, and
it shall state the number of shares voted.

        Section 2.07 BUSINESS AT ANNUAL MEETING. To be properly brought before
the meeting, business must be either (a) specified in the notice of meeting (or
any supplement thereto) given by or at the direction of the Board, (b) otherwise
properly brought before the meeting by or at the direction of the Board, or (c)
otherwise properly brought before the meeting by a stockholder who was a
stockholder of record at the time of the giving of notice provided for in this
Bylaw, who is entitled to vote at the meeting and who complies with the notice
procedures set forth in this Bylaw. In addition to any other applicable
requirements, for business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal offices of the Corporation
not less than 50 days nor more than 75 days prior to the meeting; provided,
however, that, in the event that less than 65 days' notice or prior public
disclosure of the date of the meeting is given or made to stockholders, notice
by the stockholder to be timely must be so received not later than the close of
business on the 15th day following the day on which such notice of the date of
the annual meeting was mailed or such public disclosure was made, whichever
first occurs. A stockholder's notice to the Secretary shall set forth as to each
matter the stockholder proposes to bring before the annual meeting: (i) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and record address of the stockholder proposing such business and any other
stockholders of the Corporation known to such stockholder to be in favor of such
proposal, (iii) the class and number of shares of capital stock of the
Corporation which are beneficially owned by such stockholder on the date of such
notice, (iv) any material interest of such stockholder in such proposal, and (v)
whether the proponent intends or is part of a group which intends to solicit
proxies from other stockholders in support of such proposal.


                                       3
<PAGE>   7

        No business shall be conducted at the annual meeting except in
accordance with the procedures set forth in this Section 2.07; provided,
however, that nothing in this Section 2.07 shall be deemed to preclude
discussion by any stockholder of any business properly brought before the annual
meeting.

        The chairman of the annual meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with this Section 2.07 and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted.

        Section 2.08 LIST OF STOCKHOLDERS. The Secretary of the Corporation
shall prepare and make, at least ten (10) days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

        Section 2.09 INSPECTORS. Prior to each meeting of the stockholders, one
or more inspectors shall be appointed by the Board, or, if no such appointment
shall have been made, such inspectors shall be appointed by the chairman of the
meeting, to act thereat. Each inspector so appointed shall first subscribe an
oath or affirmation faithfully to execute the duties of an inspector at such
meeting with strict impartiality and according to the best of his or her
ability. Such inspectors shall take charge of the ballots at such meeting, count
the ballots cast on any question and deliver a written report of the results
thereof to the secretary of such meeting. The inspectors need not be
stockholders of the Corporation. Any officer of the Corporation may be an
inspector on any question other than a vote for or against his or her election
to any position with the Corporation or on any other question in which he or she
may be directly interested other than as a stockholder.

        Section 2.10 REGULATIONS FOR CONDUCT OF STOCKHOLDERS MEETING. The Board
may adopt by resolution such rules and regulations for the conduct of the
meeting of stockholders as it shall deem appropriate. Except to the extent
inconsistent with such rules and regulations adopted by the Board, the chairman
of any meeting of stockholders shall have the right and authority to prescribe
such rules, regulations and procedures and to do all such acts as, in the
judgment of such chairman, are appropriate for the proper conduct of the
meeting. Such rules, regulations or procedures, whether adopted by the Board or
prescribed by the chairman of the meeting, may include, without limitation, the
following: (i) the establishment of an agenda or order of business for the
meeting; (ii) rules and procedures for maintaining order at the meeting and the
safety of those present; and (iii) limitations on the time allotted to questions
or comments by participants. Unless and to the extent determined by the Board or
the chairman of the meeting, meetings of stockholders shall not be required to
be held in accordance with the rules of parliamentary procedure.

                               BOARD OF DIRECTORS

        Section 3.01 GENERAL POWERS. The property, business and affairs of the
Corporation shall be managed by the Board, who may exercise all such powers of
the Corporation and do all such lawful acts and things as are not by Delaware
Law, by the Certificate of Incorporation or by these Bylaws directed or required
to be exercised or done by the stockholders.

        Section 3.02 NUMBER. The exact number of directors shall be fixed from
time to time, within the limits specified in the Certificate of Incorporation,
by resolution of the Board.

        Section 3.03 ELECTION OF DIRECTORS.

        (a) Voting -- The directors shall be elected annually by the
stockholders of the Corporation and the persons receiving the greatest number of
votes, up to the number of directors to be elected, shall be the persons then
elected. The election of directors is subject to any provisions contained in the
Certificate of Incorporation relating thereto, including any provisions for a
classified board and for cumulative voting.

        (b) Nomination of Directors -- Only persons who are nominated in
accordance with the following procedures shall be eligible for election as
directors. Nominations of persons for election to the Board may be made at a
meeting of stockholders by or at the direction of the Board, by any Nominating
Committee or person appointed by the Board, or by any stockholder of the
Corporation entitled to vote for the election of directors at the meeting who
complies with the notice procedures set forth in this Section 3.03(b). Such
nominations, other than those made by or at the direction of the Board, shall be
made pursuant to timely notice in writing to the Secretary of the Corporation.
To be timely, a stockholder's notice shall be delivered to or mailed and
received at the principal offices of the Corporation not less than 50 days nor
more than 75 days prior to the meeting; provided, however, that in the event
that less than 65 days' notice or prior public disclosure of the date of the
meeting is given or made to stockholders, notice by the stockholder to be timely
must be so received not later than the close of business on the 15th day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made, whichever first occurs. Such stockholder's
notice to the Secretary shall set forth (a) as to each person whom the
stockholder proposes to nominate for election or re-election as a director: (i)
the name, age, business address and residence address of the person, (ii) the
principal occupation or employment of the person, (iii) the class and number of
shares of capital stock of the Corporation which are beneficially owned by the
person, and (iv) any other information relating to the person that is required
to be disclosed in solicitations for proxies for election of directors pursuant
to Rule 14A under the Securities Exchange Act of 1934, as amended; and (b) as to
the stockholder giving the notice: (i) the name and record address of such
stockholder and (ii) the class and number of shares of capital stock of the
Corporation which are beneficially owned by such stockholder. The Corporation
may require any proposed nominee to furnish such other information as may
reasonably be required by the Corporation to determine the eligibility of such
proposed nominee to serve as a director of the Corporation. No person shall be
eligible for election as a director of the Corporation unless nominated in
accordance with the procedures set forth herein.


                                       5
<PAGE>   9

        The chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure and, if the chairman should so determine, the chairman shall
so declare to the meeting, and the defective nomination shall be disregarded.

        Section 3.04 RESIGNATIONS. Any director of the Corporation may resign at
any time by giving written notice to the Board or to the Secretary of the
Corporation. Any such resignation shall take effect at the time specified
therein, or, if the time be not specified, it shall take effect immediately upon
its receipt; and unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

        Section 3.05 VACANCIES. Except as otherwise provided in the Certificate
of Incorporation, any vacancy in the Board, whether because of death,
resignation, disqualification, an increase in the number of directors, or any
other cause, may be filled by vote of the majority of the remaining directors,
although less than a quorum. Each director so chosen to fill a vacancy shall
hold office until his or her successor shall have been elected and shall qualify
or until such director shall resign or shall have been removed.

        Section 3.06 FIRST MEETING. The Board shall meet as soon as practicable
after each annual election of directors and notice of such first meeting shall
not be required.

        Section 3.07 REGULAR MEETINGS. Regular meetings of the Board may be held
at such times as the Board shall from time to time by resolution determine. If
any day fixed for a regular meeting shall be a legal holiday at the place where
the meeting is to be held, then the meeting shall be held at the same hour and
place on the next succeeding business day not a legal holiday. Except as
provided by law, notice of regular meetings need not be given.

        Section 3.08 SPECIAL MEETINGS. Special meetings of the Board may be
called at any time by the Chairman of the Board, the Chief Executive Officer or
by the Secretary upon the written request of any two (2) directors. Such
meetings shall be held at the principal office of the Corporation, or at such
other place or places, within or without the State of Delaware, as the person or
persons calling the meeting may designate.

        Section 3.09 COMMITTEES. The Board may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the Corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members present at any meeting and not disqualified from voting, whether or not
such member or members constitute a quorum, may unanimously appoint another
member of the Board to act at the meeting in the place of any absent or

registrar who has signed, or whose facsimile signature has been placed upon, any
such certificate, shall have ceased to be such officer, transfer agent or

A record shall be kept of the respective names of the persons, firms or
corporations owning the stock represented by such certificates, the number and
class of shares represented by such certificates, respectively, and the
respective dates thereof, and in case of cancellation, the respective dates of
cancellation. Every certificate surrendered to the Corporation for exchange or

merger of Science Applications, Inc., a wholly-owned subsidiary of the
Corporation ("SAI"), with and into the Corporation (the "1984 Reorganization")
in exchange for shares of Common Stock, par value $.05 per share, of the
Corporation ("Old Common Stock") which, in turn, were issued in the merger of
SAITEMP Company, a wholly-owned subsidiary of the Corporation, with and into SAI
(the "1981 Reorganization") in exchange for shares of Common Stock, par value
$.05 per share, of SAI ("SAI Common Stock") shall be subject to the same
contractual or other restrictions, if any, that were applicable immediately
prior to the effective time of the 1981 Reorganization to the shares of SAI
Common Stock that were exchanged in the 1981 Reorganization for the shares of
Old Common Stock that were, in turn, exchanged in the 1984 Reorganization for
such shares of Class B Common Stock.

        (c) All shares of Class B Common Stock of the Corporation issued
subsequent to the effective time of the 1984 Reorganization upon exercise of
options granted prior to the effective time of the 1981 Reorganization under any
of SAI's stock option plans ("Options") which were converted into Options to
purchase shares of Old Common Stock in the 1981 Reorganization but which were
not converted into Options to purchase shares of Class A Common Stock in the
1984 Reorganization shall be subject to the same contractual or other
restrictions, if any, that would have


                                       13
<PAGE>   17

been applicable to the shares of SAI Common Stock issuable upon exercise of such
Options if such Options had been exercised immediately prior to the effective
time of the 1981 Reorganization.

        (d) To the extent that shares are represented by certificates, all
restrictions on the transfer shall be noted conspicuously on the certificate
representing such shares and with respect to uncertificated shares such
restrictions shall be noted conspicuously in any ownership statement delivered
to the stockholder by the Corporation. The transfer restrictions applicable to
any outstanding shares shall be enforceable against the holder of the restricted
shares or any successor or transferee of the holder including an executor,
administrator, trustee, guardian or other fiduciary entrusted with the
responsibility for the person or estate of the holder.

        Section 6.02 TRANSFERS OF STOCK. Transfers of shares of stock of the
Corporation shall be made only on the books of the Corporation by the registered
holder thereof, or by the attorney of the registered holder thereunto authorized
by power of attorney duly executed and filed with the Secretary, or with a
transfer clerk or a transfer agent appointed as provided in Section 6.03, and
with respect to shares represented by certificates upon surrender of the
certificate or certificates for such shares properly endorsed, and with respect
to certificateless shares, upon the execution by the transferor and transferee
of all transfer documents in such form as the Corporation shall reasonably
require, and, with respect to all shares, upon the payment of all taxes thereon.
The person in whose name shares of stock stand on the books of the Corporation
shall be deemed the owner thereof for all purposes as regards the Corporation.
Whenever any shares are pledged for collateral security such fact shall be
reflected on the books of the Corporation.

        Section 6.03 REGULATIONS. The Board may make such rules and regulations
as it may deem expedient, not inconsistent with these Bylaws, concerning the

another may be issued in its place upon proof of such loss, theft, destruction,
or mutilation and upon the giving of a bond of indemnity to the Corporation in
such form and in such sum as the Board may direct; provided, however, that a new
certificate or uncertificated share may be issued without requiring any bond
when, in the judgment of the Board, or the Corporate Secretary, it is proper so
to do.

        Section 6.05 FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORDS.
In order that the Corporation may determine the stockholders entitled to notice

entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any other
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board may fix, in advance, a record date, which shall not be more

in the Plan, all designations, determinations, interpretations and other

persons claiming entitlements under the Plan. In no event shall a Committee

        3.4 COMMITTEE DELEGATION. Except with respect to making grants of Awards

4. SHARES OF STOCK SUBJECT TO THE PLAN

        4.1 GENERAL LIMITATION. Subject to the provisions of Section 4.2, the
maximum number of shares of Stock that may be delivered to Participants and
their beneficiaries under the Plan shall be equal to the sum of: (i) 6,000,000
shares of Stock; (ii) any shares of Stock available for future awards under the
Science Applications International Corporation 1998 Stock Option Plan ("1998
Plan") as of September 30, 1999, and any shares of Stock that are represented by
Options granted under the 1998 Plan which are forfeited, expire or are canceled
without delivery of shares of Stock, which are used to satisfy tax withholding
on option exercises or which result in the forfeiture of shares of Stock back to
the Company on or after September 30, 1999; and (iii) for each calendar year
after 1999, there shall be added five percent (5%) of the Outstanding Shares of
Stock as of the first business day of such calendar year; provided, however, in
no event shall the number of shares of Stock available for future awards under
the 1998 Plan ever exceed fifteen percent (15%) of the Outstanding Shares.

        To the extent any shares of Stock covered by an Award are not delivered
to a Participant or beneficiary because the Award is forfeited, canceled,
expires without being exercised, or the shares of Stock are not delivered
because the Award is settled in cash or used to satisfy applicable tax
withholding obligations, such shares shall not be deemed to have been delivered
for purposes of determining the maximum number of shares of Stock available for
delivery under the Plan.

        If the Exercise Price of any Option granted under the Plan or the 1998
Plan is satisfied by tendering shares of Stock to the Company (by either actual
delivery or by attestation), only the number of shares of Stock issued net of
the shares of Stock tendered shall be deemed delivered for purposes of
determining the maximum number of shares of Stock available for delivery under
the Plan.

        Any shares of Stock covered by a Substitute Award shall not be deemed to
have been delivered for purposes of determining the maximum number of shares of
Stock available for delivery under the Plan.


                                       6
<PAGE>   7

        4.2 ADDITIONAL LIMITATIONS. The following additional maximum limitations
on shares of Stock that may be delivered are imposed under the Plan:

               (a) The maximum number of shares of Stock that may be issued
        under Options intended to be Incentive Stock Options shall be 8,000,000
        shares;

               (b) The maximum number of shares of Stock that may be covered by
        Awards granted to any one Eligible Individual shall be 500,000 shares
        during any calendar year;

               (c) To the extent that the aggregate Fair Market Value
        (determined on the date of grant) of Shares subject to an Option
        designated as an Incentive Stock Option becomes exercisable for the
        first time by an Eligible Individual in any calendar year exceeds
        $100,000 (or such greater amount as may be established in the Code, from
        time to time), then to that extent the Option shall not be treated as an
        Incentive Stock Option, but the remaining portion shall retain
        eligibility as an Incentive Stock Option.

        In determining the maximum number of shares of Stock in Section 4.2(a),
shares used to satisfy applicable tax withholding requirements, if any, shall be
deemed delivered and the gross number of shares which would have been issued in
a cash exercise shall be deemed delivered even if the Exercise Price is
satisfied by tendering shares of Stock to the Company.

        4.3 ADJUSTMENTS. In the event that the Committee determines that any
corporate transaction or distribution (including, without limitation, any stock
split, stock dividend, extraordinary cash dividend, issuance of warrants or
other rights to purchase Stock or other securities of the Company,
recapitalization, reorganization, merger, consolidation, split-up, spin-off,
repurchase, combination or exchange of shares) affects the Stock such that an
adjustment is determined by the Committee to be appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan, then the Committee shall, in such manner as it
may deem equitable, adjust any or all of (i) the number of shares of Stock or
other securities of the Company (or number and kind of other securities or
property) with respect to which Awards may be granted under Sections 4.1 and
4.2; (ii) the number of shares of Stock or other securities of the Company (or
number and kind of other securities and property) subject to outstanding Awards;
and (iii) the Exercise Price or other terms and conditions of any Award or, if
deemed appropriate, the Committee may make provision for a cash payment to the
holder of an outstanding Award in full satisfaction of such Award.

5. ELIGIBILITY AND PARTICIPATION

        5.1 GENERAL. Subject to the terms and conditions of the Plan, the
Committee shall determine and designate, from time to time, from among the
Eligible Individuals (including transferees of Eligible Individuals to be extent
the transfer is permitted by the Plan and the applicable Award Agreement) those
persons who will be granted one or more Awards under the Plan and thereby become
Participants in the Plan, provided that no Incentive Stock Option shall be
granted to any person who, at the time of the grant, is not an employee of the
Company or a Subsidiary. Awards may be granted


                                       7
<PAGE>   8

on conditions specified by the Committee, including, without limitation, the
condition that the Eligible Individual acquire, agree to acquire or maintain
ownership of a specified number of shares of Stock. Awards may be granted as
alternatives to or replacement of Awards outstanding under the Plan or any other
plan or arrangement of the Company or an Affiliate (including a plan or
arrangement of a business or entity, all or a portion of which is acquired by
the Company or an Affiliate).

        5.2 NON-U.S. ELIGIBLE INDIVIDUALS AND AFFILIATES. Notwithstanding any
provision of the Plan to the contrary, in order to foster and promote
achievement of the purposes of the Plan or to comply with provisions of laws in
other countries in which the Company or its Affiliates operate or have employees
or consultants, the Committee, in its discretion, shall have the power and
authority to (i) determine which (if any) Eligible Individuals rendering
services or employed outside the United States are eligible to participate in
the Plan or any type of Award hereunder; (ii) determine which non-United
States-based Affiliates or operations (e.g., branches, representative offices)
participate in the Plan or any type of Award hereunder; (iii) modify the terms
and conditions of any Awards made to such Eligible Individuals or with respect
to such non-United States-based Affiliates or operations; and (iv) establish
sub-plans, modified exercise, payment and other terms and procedures to the
extent deemed necessary or desirable by the Committee.

6. OPTIONS AND SARS

        6.1 OPTIONS. The Options granted pursuant to the Plan may be Incentive

reflected in the Award Agreement.

        6.2 SARS. A SAR entitles the Participant to receive in cash or shares of
Stock (as determined in accordance with subsection 6.4) value equal to (or
otherwise based on) the excess of (i) the Fair Market Value of the number of
shares of Stock specified in the Award Agreement over (ii) the Exercise Price
for the SAR Award established by the Committee. Prior to the grant of any SARs
under the Plan, the Board of Directors must specifically authorize the Committee

established by the Committee or shall be determined by a method or formula
established by the Committee at the time the Option or SAR is granted; except

the Fair Market Value of a share of Stock on the date of grant with respect to
Nonqualified Stock Options or SARs and (ii) one-hundred percent (100%) of the
Fair Market Value of a share of Stock on the date of grant with respect to
Incentive Stock Options. Unless otherwise specified in the Award Agreement, the
Exercise Price shall be the Fair Market Value of a share of Stock on the date of
grant.

               (a) An Option or a SAR shall be exercisable only in accordance
        with such terms and conditions and during such periods as may be

<PAGE>   9

        may, in its discretion, provide that such an Option or SAR may be
        exercised in whole or in part, in installments, cumulative or otherwise,
        for any period of time specified by the Committee or based on
        performance on other criteria established by the Committee. The
        Committee may authorize loans in connection with Option exercises on
        terms established by the Committee.

               (b) Options and SARs shall be exercised pursuant to procedures
        established by the Committee, which may include written, electronic or
        voice procedures as may be specified by the Committee. The Committee may
        require full payment of the Exercise Price (in the case of an Option)
        plus payment of any required withholding amounts as a condition to
        exercise or may, in the alternative, satisfy such withholding obligation
        by withholding shares of Stock or cash, or any combination thereof,
        otherwise payable in settlement of the exercise of an Award, or by any
        exercise and withholding procedures it determines to be applicable to a
        particular Option or SAR. The Committee may also permit payment of all
        or part of the Exercise Price to be satisfied by tendering (either by
        actual delivery or by attestation) shares of Stock acceptable to the
        Committee (which may be required to have been held by the Participant
        for at least six months) valued at their Fair Market Value as of the
        date of exercise.

        6.5 EXPIRATION AND TERMINATION. An Option and all rights and obligations
thereunder shall expire on the date to be determined by the Committee and set
forth in the Award Agreement; provided, however, that in no event shall such
date be later than ten (10) years from the date an Incentive Stock Option is
granted. A SAR and all rights and obligations thereunder shall terminate upon
the occurrence of such events as determined by the Committee and set forth in
the Award Agreement.

        6.6. SETTLEMENT OF AWARD. Shares of Stock delivered pursuant to the
exercise of an Option or, if applicable, a SAR shall be subject to such
conditions, restrictions and contingencies as the Committee may establish
pursuant to the Plan and Award Agreement. Settlement of SARs may be made in
shares of Stock (valued at their Fair Market Value at the time of exercise), in
cash or in a combination thereof, as determined in the discretion of the
Committee.

        6.7 AMENDMENT TO AWARDS. The Committee may waive any conditions or
rights under, amend any terms of, or alter, suspend, discontinue, cancel or
terminate, any Award theretofore granted, prospectively or retroactively.

        6.8 CANCELLATION OF AWARDS. Any provision of this Plan or any Award
Agreement to the contrary notwithstanding, the Committee may cause any Award
granted hereunder to be canceled in consideration of a cash payment or
alternative Award made to the holder of such canceled Award equal in value to
the Fair Market Value of such canceled Award.

        7.1 GRANT. Subject to the terms and provisions of the Plan, the
Committee, at any time and from time to time, may grant Awards of Vested Stock,
Restricted Stock or Restricted Stock Units in such amounts and to such Eligible
Individuals as the Committee shall determine; provided, however, that


                                       9
<PAGE>   10

prior to the grant of any Awards of Restricted Stock Units under the Plan, the
Board of Directors must specifically authorize the Committee to award Restricted
Stock Units. With respect to Awards of Restricted Stock or Restricted Stock
Units, the applicable Award Agreement shall contain the terms and conditions of
each such grant, which may include, without limitation, the duration of the
Award, vesting and forfeiture provisions, a requirement that Participants pay a
specified price for each share of Restricted Stock, restrictions based on
achievement of specified performance goals and restrictions under federal, state
or foreign securities laws.

        7.2 PAYMENT. Unless otherwise specified on the Award Agreement,
Restricted Stock Units shall have a value equal to the Fair Market Value of a
share of Stock and shall be paid in cash, share(s) of Stock or other securities
or property or any combination thereof, as determined by the Committee, upon the
lapse of restrictions applicable to the grant or otherwise in accordance with
the applicable Award Agreement.

        7.3 DIVIDENDS, DISTRIBUTIONS AND VOTING RIGHTS. If a dividend or other
distribution is made with respect to the Stock during a period in which
restrictions apply to a Restricted Stock Award or prior to payment of a
Restricted Stock Unit Award, the Committee, either in the Award Agreement or at
the time of distribution if not otherwise specified in the Award Agreement,
shall determine how such dividend or distribution shall affect the applicable
Award, whether by payment of the dividend or distribution to the Award holder,
by adjustment of the Award or otherwise. Unless otherwise specified in the Award
Agreement, a holder of Restricted Stock shall have full voting rights with
respect to shares of Restricted Stock and holders of Restricted Stock Units
shall have no voting rights with respect to shares of Stock to which the Award
relates.

8. PERFORMANCE AWARDS.

        8.1 GRANT. Subject to the terms and provisions of the Plan, the
Committee shall have the authority to grant Performance Awards, which consist of
rights which are:

               (a) denominated in cash or shares of Stock;

               (b) valued in relation to the achievement of performance goals
        during such reference periods as the Committee shall establish; and

               (c) payable at such time or times and in such form as the
        Committee shall determine.

        8.2 TERMS AND CONDITIONS. Subject to the terms of the Plan and any
applicable Award Agreement, the Committee shall establish the performance
measure(s) to be achieved during any performance period, the length of the
performance period, the amount of any Performance Award and the amount and kind
of any payment or transfer to be made pursuant to any Performance Award.


                                       10
<PAGE>   11

        8.3 PERFORMANCE MEASURES. The performance measure(s) to be used for
purposes of Awards to Named Executive Officers which are designed to qualify for
the Performance-Based Exception shall be chosen from among the following
alternatives:

               (a) earnings per share;

               (b) net income;

               (c) income from operations;

               (d) earnings before interest and taxes;

               (e) earnings before interest, taxes, depreciation and
        amortization;

               (f) return on assets;

               (g) return on equity;

               (h) return on capital;

               (i) total stockholder return;

               (j) revenue growth;

               (k) new business generation;

               (l) cash flow;

               (m) employee turnover;

               (n) human resources;

               (o) mergers, acquisitions, investments, joint ventures or sales
        or divestitures of assets, businesses or subsidiaries;

               (p) litigation;

               (q) information services; or

               (r) cost reductions or savings.

        The Committee shall have the discretion to adjust the determinations of
the degree of attainment of the pre-established performance goals; provided,
however, that Awards which are designed to


                                       11
<PAGE>   12

qualify for the Performance-Based Exception and which are held by Named
Executive Officers, may not be adjusted upward (the Committee shall retain the
discretion to adjust each Award downward).

        In the event that applicable tax and/or securities laws change to permit
Committee discretion to alter the applicable performance measures without
obtaining stockholder approval of such changes, the Committee shall have sole
discretion to make such changes without obtaining stockholder approval.

9. OTHER STOCK-BASED AWARDS.

        The Committee, subject to the terms of the Plan, shall have the
authority to grant to Eligible Individuals other Stock-based Awards, which
encompass any type of Award which is related to shares of Stock, whether or not
payable in shares of Stock, deemed by the Committee to be consistent with the
purposes of the Plan. Subject to the terms of the Plan and any applicable Award
Agreement, the Committee shall determine the terms and conditions of any such
other Stock-based Award and make grants of such Awards to Eligible Individuals
as determined by the Committee.

10. CHANGE IN CONTROL.

        Subject to the provisions of Section 4.3 (relating to the adjustment of
shares of Stock) and except as provided in the Award Agreement reflecting the
applicable Award, upon the occurrence of a Change in Control, all outstanding
Awards shall become fully vested and all outstanding Options and SARs shall
become immediately exercisable.

11. BENEFICIARY DESIGNATION.

        In the event of the death of a Participant holding an Award which
provides for some payment or benefit following the death of the Participant, the
benefit or payment payable under the Award upon the death of the Participant
shall be payable to the estate of the Participant, provided that, in its
discretion, the Committee may, in the Award Agreement or pursuant to the Award
Agreement, permit the Participant to name a beneficiary or beneficiaries to whom
any benefit under the Award is to be paid in case of the Participant's death.
Any such designation, if permitted by the Committee, shall be effective only in
accordance with such procedures as may be established by the Committee and on
forms prescribed by the Committee.

12. DEFERRALS.

        The Committee, in an Award Agreement or otherwise, may permit a
Participant to defer such Participant's receipt of the payment of cash or
delivery of shares of Stock that would otherwise be due to such Participant by
virtue of the exercise of an Option or a SAR, the lapse or waiver of
restrictions with respect to Restricted Stock or Restricted Stock Units or the
satisfaction of any requirements or goals with respect to Performance Awards.


                                       12
<PAGE>   13

13. TAX WITHHOLDING.

        All distributions under the Plan are subject to withholding of all
applicable taxes, and the Committee may condition the delivery of shares of
Stock or other benefits on satisfaction of all applicable withholding
requirements. The Committee, in its discretion and subject to such requirements
as the Committee may prescribe, may permit such withholding obligations to be
satisfied through any combination of the following: cash payment by the
Participant, payroll withholding of the Participant's salary, wages or other
compensation, surrender of shares of Stock which the Participant already owns
(either by actual surrender or attestation) or surrender of shares of Stock or
other benefits to which the Participant is otherwise entitled (e.g., upon
exercise of an Option or a SAR) under the terms of the Plan.

14. TRANSFERABILITY.

        Except as otherwise provided by the Committee in an Award Agreement or
otherwise, Awards under the Plan may not be anticipated, assigned, attached,
garnished, optioned, transferred or made subject to any creditor's process,
whether voluntarily, involuntarily or by operation of law. Except as otherwise
provided in an Award Agreement, an Option or a SAR may be exercised during the
lifetime of the Optionee or Award holder only by him or her or by his or her
legal representative. This Section 14 shall not preclude a Participant from
designating a beneficiary if permitted by the Committee pursuant to Section 11
of the Plan.

15. LIMITATION ON IMPLIED RIGHTS.

        (a) Neither a Participant nor any other person shall, by reason of
participation in the Plan, acquire any right in or title to any assets, funds or
property of the Company or any Affiliate whatsoever including without
limitation, any specific funds, assets or other property which the Company or
any Affiliate, in its or their sole discretion, may set aside in anticipation of
a liability under the Plan. A Participant shall have only a contractual right to
the Stock or amounts, if any, payable under the Plan, unsecured by any assets of
the Company or any Affiliate, and nothing contained in the Plan shall constitute
a representation or guarantee that the assets of the Company or any Affiliate
shall be sufficient to pay any benefits to any person.

        (b) An Eligible Individual's or Participant's employment with the
Company or an Affiliate, if applicable, is not for any specified term and may be
terminated by such Eligible Individual/Participant or the Company or the
Affiliate at any time, for any reason, with or without cause, notwithstanding
the vesting or other terms and conditions of any outstanding Awards. Nothing in
this Plan nor in any Award Agreement shall confer upon any Eligible Individual
or Participant any promise or commitment by the Company or an Affiliate
regarding future positions, future work assignments, future compensation or any
other term or condition of employment or affiliation.


                                       13
<PAGE>   14

16. GOVERNMENT AND STOCK EXCHANGE REGULATIONS.

        The Committee may refuse to issue or transfer any Shares or other
consideration under an Award if, acting in its sole discretion, it determines
that the issuance or transfer of such Shares or such other consideration might
violate any applicable law or regulation or entitle the Company to recover the
same under Section 16(b) of the Exchange Act, and any payment tendered to the
Company by a Participant, other holder or beneficiary in connection with the
exercise of such Award shall be promptly refunded to the relevant Participant,
holder or beneficiary. Without limiting the generality of the foregoing, no
Award granted hereunder shall be construed as an offer to sell securities of the
Company, and no such offer shall be outstanding, unless and until the Committee
in its sole discretion has determined that any such offer, if made, would be in
compliance with all applicable requirements of the U.S. federal and state
securities laws and any other laws to which such offer, if made, would be
subject.

        Upon the exercise of an Option (or upon a payment event under another
Award) at a time when there is not in effect a registration statement under the
Securities Act of 1933 or a similar statute (the "Act") relating to the Stock
issuable upon exercise or payment thereof and available for delivery a
prospectus meeting the requirements of Section 10(a)(3) of said Act or if the
rules or interpretations of the Securities and Exchange Commission so require,
the Stock may be issued only if the holder represents and warrants in writing to
the Company that the shares purchased are being acquired for investment and not
with a view to distribution thereof.

        The Company is under no duty to ensure that shares of Stock may legally
be delivered under the Plan, and shall have no liability to Award recipients in
the event such delivery of shares of Stock may not be made.

17. AMENDMENTS, SUSPENSIONS OR TERMINATION OF PLAN.

        The Board or the Operating Committee of the Board may at any time
suspend or terminate the Plan and may amend it from time to time in such
respects as the Board or the Operating Committee may deem advisable in order
that Awards granted thereunder shall conform to any change in the law, or in any
other respect which the Board 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 votes cast at a duly held stockholders
meeting (at which a quorum representing a majority of all outstanding voting
stock is, either in person or by proxy, present and voting on the Plan
amendment), increase the maximum number of shares for which Awards may be
granted under the Plan (in the aggregate or to any single individual), except as
specified in Section 4.3, or change the class of employees eligible to
participate in the Plan.

18. NO IMPLIED RIGHTS OR OBLIGATIONS.

        The Company, in establishing and maintaining this Plan as a voluntary
and unilateral undertaking, expressly disavows the creation of any rights in
Eligible Individuals, Participants or others claiming entitlement under the Plan
or any obligations on the part of the Company, any Affiliate or the


                                       14
<PAGE>   15

Committee, except as expressly provided herein. In particular, no third-party
beneficiary rights shall be created under the Plan.

        Without limiting the generality of the foregoing, the Company disavows
any undertaking to maintain the tax-qualified status of Options designated as
Incentive Stock Options or to assure the tax treatment of any particular Award,
including the deferral or transfer of any Award benefits, as may be permitted by
the Committee.

19. AWARDS UNDER OTHER PLANS OR SUB-PLANS.

        The Company or an Affiliate may grant awards relating to Stock under
other plans or programs. The Committee in its discretion may determine that such
awards shall be settled in the form of shares of Stock issued under this Plan.
Such shares of Stock shall be treated for all purposes under the Plan similar to
shares of Stock issued in settlement of Awards and shall, when issued, reduce
the number of shares of Stock available under Section 4, in accordance with the
same principles applicable under Section 4 in the case of Awards originally
granted under the Plan.

20. NO TRUST OR FUND CREATED.

        Neither the Plan or any Award shall create or be construed to create a
trust or separate fund of any kind or a fiduciary relationship between the
Company or any Affiliate and a Participant or any other person. To the extent
that any person acquires a right to receive payments from the Company or any
Affiliate pursuant to an Award, such right shall be no greater than the right of
any unsecured general creditor of the Company or any Affiliate.

21. TERMINATION.

        The Plan shall continue in effect until April 9, 2019, unless earlier
terminated by the Board or Operating Committee pursuant to Section 17, provided
that no Incentive Stock Options may be granted after April 9, 2009.

22. GOVERNING LAW.

        The validity, construction and effect of the Plan, the Award Agreements
and any rules, regulations or procedures relating thereto shall be determined in
accordance with the laws of the State of Delaware.

INDEPENDENT AUDITORS' REPORT


Retirement Plans Committee and Participants of the
Science Applications International Corporation
Cash or Deferred Arrangement:

We have audited the accompanying statement of net assets available for benefits
of the Science Applications International Corporation Cash or Deferred
Arrangement (the "Plan") as of December 31, 1999, and the related statement of
changes in net assets available for benefits for the year then ended. These
financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 1999, and the changes in net assets available for benefits of the
Plan for the year then ended in conformity with accounting principles generally
accepted in the United States of America.

Our audit was conducted for the purpose of forming an opinion on the basic 1999
financial statements taken as a whole. The supplemental schedule listed in the
Table of Contents is presented for the purpose of additional analysis and is not
a required part of the basic 1999 financial statements, but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
Such supplemental schedule has been subjected to the auditing procedures applied
in our audit of the basic 1999 financial statements and, in our opinion, is
fairly stated in all material respects in relation to the basic 1999 financial
statements taken as a whole.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Retirement Plan's Committee
and Participants of the Science Applications
International Corporation Cash or Deferred Arrangement

In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Science Applications International Corporation Cash or Deferred
Arrangement (the "Plan") at December 31, 1998, and the changes in net assets
available for benefits for the year ended December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
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 audit provides a
reasonable basis for the opinion expressed above. We have not audited the
financial statements of the Science Applications International Corporation Cash
or Deferred Arrangement for any period subsequent to December 31, 1998.

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1999 AND 1998
- --------------------------------------------------------------------------------


1.      DESCRIPTION OF PLAN

        GENERAL - The Science Applications International Corporation Cash or
        Deferred Arrangement (the "Plan") is a defined contribution plan. It is
        subject to the provisions of the Employee Retirement Income Security Act
        of 1974 ("ERISA"). The Plan consists of a deferred fund which is the
        fund in which assets acquired by the Plan in its function as a qualified
        Cash or Deferred Arrangement are held and accounted for. Participants
        should refer to the Plan document for a more complete description of the
        Plan's provisions.

        The authority to control and manage the operation and administration of
        the Plan is vested in the Science Applications International Corporation
        ("SAIC" or the "Company") Retirement Plans Committee (the "Committee")
        whose members are the named fiduciaries for purposes of Section 402(a)
        of ERISA.

        ELIGIBILITY - Generally, employees of SAIC and its subsidiaries who have
        adopted the Plan are eligible to participate upon commencing employment,
        except for employees in groups designated as ineligible.

        CONTRIBUTIONS - The Plan permits participants to elect to defer up to
        18% of their eligible compensation for the Plan year and to have such
        deferred amount contributed directly by the Company to the Plan. The
        Company, at its discretion, may make a matching contribution equal to a
        specified percentage of the aggregate amounts deferred by participants.
        The match is only provided on eligible participant deferrals of up to
        10% of compensation. In 1999 and 1998, the Company contributed 50% of
        the first $2,000 of a participant's annual deferred compensation and 15%
        of such deferred compensation above $2,000. During 1999 and 1998, the
        Company matching contribution was allocated to the SAIC stock fund. In
        addition, the Company, at its discretion, may make an additional
        contribution to the Plan for the benefit of non-highly-compensated
        participants in order to comply with Section 401(k)(3) of the Internal
        Revenue Code. The Company made no additional contributions for the
        benefit of non-highly compensated participants during 1999 and 1998.

        The Company's contribution to the Plan is to be paid in cash unless the
        Company's Board of Directors determines to make the contribution in
        shares of SAIC Class A Common Stock (the "Common Stock") or another
        form. Contributions to the Plan cannot be in excess of the maximum
        amount deductible for federal income tax purposes.

        Employees hired prior to January 1, 1995 are immediately eligible for
        the Company matching contributions. Employees hired on or after January
        1, 1995, who have elected to participate, are eligible for Company
        matching contributions if they have attained age 21 and have both 12
        calendar months of employment and 850 hours of service.

        INVESTMENT FUNDS - Participants may direct the investment of their
        contributions to the following fund options offered by the Plan:

            Vanguard GNMA Fund - Invests in fixed income securities guaranteed
            by the U.S. government.

            Vanguard 500 Index Fund - Invests in common stocks.

            Vanguard Prime Money Market Fund - Invests in money market
            instruments.

            Vanguard Wellesley Income Fund - Invests in fixed income securities
            and common stocks.

            Vanguard Windsor Fund - Invests in common stocks.

            Vanguard International Growth Fund - Invests in common stock of
            companies based outside the United States.

            Vanguard LifeStrategy Moderate Growth Fund - Invests in common
            stocks and bonds.

            Vanguard LifeStrategy Growth Fund - Invests in common stocks and
            bonds.

            SAIC Exchangeable Stock Fund - Invests primarily in SAIC Class A
            Common Stock and is participant directed to the extent that
            participant contributions were used to purchase SAIC stock.

            SAIC Non-Exchangeable Stock Fund - This fund is a non-participant
            directed fund created to invest the Company's matching
            contributions primarily in SAIC Class A Common Stock.

            The SAIC Stock Purchase Fund - This fund is a temporary holding fund
            designed to hold participant and Company contributions until the
            following SAIC common stock quarterly trade date. Pending the
            quarterly trade, the contributions are invested in the Vanguard
            Prime Money Market Fund.

        Participants may transfer their funds among investment options and
        change their future contribution allocations at any time under rules
        prescribed by the Committee.

        During 1999, the Company enacted a provision of the Plan requiring
        participants who have separated from service with SAIC to transfer their
        balances in the SAIC Stock Funds to one or more of the Vanguard funds
        offered by the Plan. If no election is made, the SAIC Stock Fund
        investments will transfer automatically to the Vanguard Prime Money
        Market Fund. The first mandatory divestiture will occur on April 28,
        2000. A final determination of the value of the mandatory divestiture
        cannot be completed at this time, however, the Company estimates that
        SAIC Stock Fund balances held by former employees to be exchanged on
        April 28, 2000 is approximately $240 million.

        PARTICIPANT ACCOUNTS - Each participant's account is credited with
        participant deferrals and Company contributions in accordance with
        provisions of the Plan. A participant is entitled to the benefit that
        can be provided from the participant's vested account balance.

        VESTING - A participant's interest in the employee deferral portion of
        the participant's account is 100% vested at all times. A participant's
        interest in Company contributions is 100% vested if the participant was
        hired prior to January 1, 1995. If the participant was hired on or after
        January 1, 1995, the participant's interest in Company contributions
        vests at a rate of 25% per year in years three through six, becoming
        fully vested after six years of service, as defined. Participants are
        deemed fully vested upon


                                      -6-
<PAGE>   11

        reaching age 59 1/2, permanent disability or death. Forfeitures, arising
        from participants withdrawing from the Plan prior to achieving 100%
        vesting are used to reduce the cost of the Company's matching
        contribution. Plan forfeitures of $596,000 and $550,000 were used to
        reduce Company matching contributions in 1999 and 1998, respectively.

        PARTICIPANT LOANS - Participants may borrow up to 50% of their vested
        account balance, up to a maximum of $50,000, excluding amounts invested
        in the SAIC Stock Fund. The maximum loan term is generally five years.
        The loans are secured by the balance in the participant's account and
        bear interest at a reasonable rate. Principal and interest are paid
        ratably through biweekly payroll deductions.

        DISTRIBUTIONS TO PARTICIPANTS - Participants receive their vested
        account balance in a single lump sum payment in cash following their
        termination of employment with the Company, retirement date, permanent
        disability or in the event of death. A participant may make withdrawals
        from the Plan prior to attaining age 59-1/2 only if the Company
        determines that the participant is incurring financial hardship. After
        attaining age 59-1/2, a participant may make withdrawals even if still
        employed by the Company.

        TAX STATUS - The Company received its latest determination letter from
        the Internal Revenue Service dated February 3, 1997, indicating the
        Plan, as then designed, was in compliance with the applicable
        requirements of the Internal Revenue Code. The Plan has been amended
        since receiving the determination letter. The Plan administrator and the
        Plan's tax counsel believe that the Plan is designed and is currently
        being operated in compliance with the applicable requirements of the
        Internal Revenue Code and is qualified and the related trust is
        tax-exempt.

        TERMINATION OF THE PLAN - Although it has not expressed any intent to do
        so, the Company has the right under the Plan to discontinue its
        contributions and to terminate the Plan at any time subject to the
        provisions of ERISA. Upon termination of the Plan, the participants
        become 100% vested in their accounts.

2.      SIGNIFICANT ACCOUNTING POLICIES

        BASIS OF ACCOUNTING - The Plan's financial statements are prepared on
        the accrual basis of accounting. Investment transactions are accounted
        for on the trade date. Dividend income is recorded on the ex-dividend
        date.

        INVESTMENT VALUATION - Investments, except for SAIC Common Stock and
        participant loans, are carried at fair value based on quoted market
        prices. A general public market for the Company's Common Stock does not
        exist; therefore, the fair market value of the Common Stock is
        determined pursuant to a stock price formula and valuation process which
        includes an appraisal prepared by an independent appraisal firm.
        Periodic determinations of fair market value of the Common Stock are
        made by the Board of Directors, with the assistance of the independent
        appraisal firm. The Board of Directors reserves the right to alter the
        formula. On August 31, 1999, the Company effected a four-for-one stock
        split payable in the form of a stock dividend. All share and per share
        information for SAIC Class A common stock has been retroactively
        restated in these financial statements to reflect this split.

        The gains or losses realized on distributions of investments and the
        unrealized appreciation or depreciation are calculated as the difference
        between the current fair market value and the fair market value of the
        investments at the beginning of the year, or purchase price if purchased
        during the year. As of December 31, 1999 and 1998, the fair market value
        of the Company's Class A Common Stock was $19.99 and $14.72 per share
        and the Plan held approximately 36,476,000 and 34,801,000 shares,
        respectively.



                                      -7-
<PAGE>   12

        It is the policy of the Committee to keep the SAIC Stock Fund invested
        primarily in Common Stock, except for estimated reserves for use in
        distributions and investment exchanges by participants. Such reserves
        are held in short-term investments. If reserves in the SAIC Stock Fund
        are less than the amount required at any given time to make requested
        distributions and investment changes, investment exchanges out of the
        SAIC Stock Fund by participants may have to be deferred.

        Participant loans are carried at the aggregate unpaid principal balance
        of loans outstanding which approximates fair value.

        BENEFITS PAYABLE - Benefit payments to participants are recorded upon
        distribution. Benefits payable to participants are not reflected in the
        accompanying financial statements. As of December 31, 1999 and 1998, net
        assets available for Plan benefits included $14,915,000 and $6,345,000,
        respectively, for participants who have elected to withdraw from the
        Plan but have not yet been paid.

        ACCOUNTING ESTIMATES - The preparation of financial statements in
        conformity with generally accepted accounting principles requires Plan
        management to make estimates and assumptions that affect the reported
        amounts of assets at the date of the financial statements and the
        reported amounts of additions and deductions during the reporting
        period. Actual results may differ from those estimates.

        RECLASSIFICATIONS - Certain amounts in the 1998 financial statements
        have been reclassified to conform to the 1999 presentation.

3.      INVESTMENT INFORMATION

        The Plan's investments are held in a trust fund. The fair value of the
        investments representing 5% or more of the Plan's assets at December 31,

5.      NET TRANSFERS FROM OTHER PLANS

        During 1999, the Company acquired several entities administering
        separate defined contribution plans. The plan assets of the active
        employees acquired by the Company were transferred to the Plan at
        various times during the year. The Company also divested an entity
        during 1999 and the Plan assets associated with the active employees in
        the new organization were transferred to the new plan.

INDEPENDENT AUDITORS' REPORT



To the Trustees and Participants of the
Telcordia Technologies Savings and Security Plan
Morristown, New Jersey


We have audited the accompanying statements of net assets available for plan
benefits of Telcordia Technologies Savings and Security Plan (the "Plan") as of
December 31, 1999, and the related statement of changes in net assets available
for plan benefits for the year then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for plan benefits of the Plan as of December
31, 1999, and the changes in net assets available for plan benefits for the year
then ended in conformity with generally accepted accounting principles in the
United States of America. Our audit was conducted for the purpose of forming an
opinion on the basic financial statements taken as a whole. The supplemental
schedule listed in the Table of Contents is presented for the purpose of
additional analysis and is not a required part of the basic financial
statements, but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The supplemental schedule is the
responsibility of the Plan's management. Such supplemental schedule has been
subjected to the auditing procedures applied in our audit of the basic financial
statements and, in our opinion, is fairly stated in all material respects when
considered in relation to the basic financial statements taken as a whole.

                        REPORT OF INDEPENDENT ACCOUNTANTS



To the Participants and the Administrative Committee
of the Bell Communications Research Savings and Security Plan

In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Bell Communications Research Savings and Security Plan (the "Plan") at
December 31, 1998, and the changes in net assets available for benefits for the
year ended December 31, 1998, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Plan's
management; our responsibility is to express an opinion on these financial
statements based on our audit. We conducted our audit 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 audit provides a reasonable basis
for the opinion expressed above. We have not audited the financial statements of
the Bell Communications Research Savings and Security Plan for any period
subsequent to December 31, 1998.

TELCORDIA TECHNOLOGIES
SAVINGS AND SECURITY PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1999 AND 1998

1.   DESCRIPTION OF PLAN

     The Telcordia Technologies Savings and Security Plan (formerly the Bell
     Communications Research Savings and Security Plan) (the "Plan") was
     established by Telcordia Technologies, Inc. ("Telcordia" or the "Company")
     to provide a convenient way for non-salaried employees to save on a regular
     and long term basis. On November 14, 1997, the Company was sold to Science
     Applications International Corporation ("SAIC"). Prior to the sale, the
     Company was owned by the Regional Bell Operating Companies ("RBOC's").

     Effective March 9, 1999, the Company changed its name to Telcordia
     Technologies.

     Effective March 17, 1999, the name of the Plan was changed to Telcordia
     Technologies Savings and Security Plan.

     The following description of the Plan provides only general information.
     Participants should refer to the Plan Prospectus for a more complete
     description of the Plan's provisions.

     GENERAL - The Plan is a defined contribution plan covering all non-salaried
     employees of the Company who have one month of service. It is subject to
     the provisions of the Employee Retirement Income Security Act of 1974
     ("ERISA").

     CONTRIBUTIONS - Each year, participants may contribute up to 16 percent of
     pretax annual compensation, as defined in the Plan. Participants may also
     contribute amounts representing distributions from other qualified defined
     benefit or contribution plans. After one year of service, the Company will
     make a matching contribution equal to 70 percent of the first 6 percent of
     compensation that a participant contributes to the Plan. In addition, after
     one year of service, the Company will make an annual discretionary
     contribution of a 1/2 percent of compensation on behalf of each
     participant. The Company's discretionary contributions are deposited into
     the SAIC Stock Purchase Fund until the following quarterly trade date and
     then into the SAIC Non Exchangeable Stock Fund. The Company's discretionary
     contributions are made during the first quarter for participant earnings of
     the previous calendar year. The Company's discretionary contributions are
     immediately vested. The Company's matching contributions are invested 50
     percent in the SAIC Non Exchangeable Stock Fund and 50 percent are invested
     in accordance with each participant's directed allocation. Contributions
     are subject to certain IRS limitations.

     PARTICIPANT ACCOUNTS - Each participant's account is credited with the
     participant's contribution and allocations of the Company's contribution
     and fund earnings, and each participant's account is charged with an
     allocation of administrative expenses. Allocations are based on participant
     earnings or account balances, as defined. The benefit to which a
     participant is entitled is the benefit that can be provided from the
     participant's vested account.



                                      -5-
<PAGE>   10

     VESTING - Participants are immediately vested in their contributions and
     the Company's discretionary contributions, plus actual earnings thereon.
     Vesting in the Company's matching contributions plus actual earnings
     thereon are based on years of continuous service. A participant is fully
     vested after five years of credited service.

     PARTICIPANT LOANS RECEIVABLE - Participants may borrow from their fund
     accounts a minimum of $1 up to a maximum of the lesser of (a) $50 less the
     participant's highest outstanding loan balance during the preceding one
     year period; or (b) 50 percent of their vested account balance.
     Additionally, loans may not exceed the vested value of the participant's
     Plan account less their vested amounts in the SAIC Stock Fund within the
     Plan. Loan transactions are treated as a transfer to (from) the investment
     fund from (to) the Loan Fund. Loan terms range from 12 to 56 months. The
     loans are secured by the balance in the participant's account and bear
     interest at a rate commensurate with local prevailing rates as determined
     quarterly by the Plan Administrator. Interest rates ranged from 9.50 to
     8.75 percent during 1999 and 1998. Principal and interest is paid ratably
     through monthly payroll deductions.

     PAYMENT OF BENEFITS - On termination of service other than by death, a
     participant may elect to receive either a lump-sum amount equal to the
     value of the participant's vested interest in his or her account, or annual
     installments not to exceed the life expectancy of the participant and
     spouse, if applicable. For termination of service due to death, a
     beneficiary may receive the value of the vested interest in his or her
     account as a lump-sum distribution, or in two annual installments, if the
     participant has so elected.

     FORFEITED ACCOUNTS - Forfeited accounts are used to reduce future Company
     contributions. Company contributions were reduced by $2 and $1 in 1999 and
     1998, respectively.

     INVESTMENT OPTIONS - The Plan is comprised of the following investments:

        - VANGUARD TOTAL BOND MARKET INDEX FUND: This participant directed fund
          invests in United States treasury obligations, federal agency mortgage
          backed obligations and investment grade corporate obligations.

        - VANGUARD EXPLORER FUND: This participant directed fund
          invests in the common stock of a diversified group of small
          capitalization companies.

        - VANGUARD 500 INDEX FUND: This participant directed fund invests in all
          of the 500 stocks that make up the Standard & Poor's 500 Composite
          Stock Price Index.

        - VANGUARD INTERNATIONAL GROWTH FUND: This participant
          directed fund invests in the common stocks of companies
          based outside of the United States.

          invests in the common stock of medium capitalization
          companies.

        - VANGUARD / WELLINGTON FUND: This participant directed fund invests
          approximately 65 percent of its assets in common stocks and the
          remaining 35 percent in bonds.

          invests in the common stock of large capitalization
          companies.



                                      -6-
<PAGE>   11

        - SAIC EXCHANGEABLE STOCK FUND: This fund invests primarily in SAIC
          class A common stock and is participant directed to the extent that
          participant contributions were used to purchase SAIC stock. Effective
          October 1999, the company announced the closing of SAIC stock funds to
          all inactive participants of the plan. Inactive participants would
          have until July 2000 to move assets held in these funds. Any remaining
          funds will be moved to the interest income fund.

        - SAIC NON EXCHANGEABLE STOCK FUND: This is a non-participant directed
          fund created to invest 50% of the Company's matching contributions and
          the Company's annual discretionary contributions in SAIC class A
          common stock. Effective October 1999, the company announced the
          closing of SAIC stock funds to all inactive participants of the plan.
          Inactive participants would have until July 2000 to move assets held
          in these funds. Any remaining funds will be moved to the interest
          income fund.

        - The SAIC STOCK PURCHASE FUND is not a participant directed investment
          option; it is a temporary holding fund designed to hold respective
          participant and Company contributions until the following SAIC common
          stock quarterly trade date. Pending the quarterly trade, the
          respective contributions are invested in the Vanguard Money Market
          Reserves Portfolio.

        - TELCORDIA TECHNOLOGIES, INC. - INTEREST INCOME FUND: This
          participant directed fund invests primarily in investment
          contracts issued by insurance companies and banks.

        - TELCORDIA TECHNOLOGIES, INC. - DIVERSIFIED TELEPHONE
          PORTFOLIO STOCK FUND: This fund invests primarily in common
          stock and has been frozen to new participant directed
          contributions since 1984.

        - TELCORDIA TECHNOLOGIES, INC. - TELEPHONE EQUITY FUND STOCK FUND: This
          fund invested in the common stock of the RBOC's. Upon the sale of the
          Company to SAIC, the fund was frozen to new participant directed
          contributions, and then closed on January 31, 1999. Any remaining
          balances that were held in Telephone Equity Fund were automatically
          transferred to the Interest Income Fund on February 1, 1999.

     Effective January 1, 2000, the Plan was amended to allow two new investment
     options, the Vanguard US Growth Fund and the Vanguard Extended Market Fund.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF ACCOUNTING - The accompanying financial statements have been
     prepared on the accrual basis of accounting in accordance with generally
     accepted accounting principles.

     USE OF ESTIMATES - The preparation of financial statements in conformity
     with generally accepted accounting principles requires management to make
     significant estimates and assumptions that affect the reported amounts of
     assets, liabilities and disclosures of contingent assets and liabilities at
     the date of the financial statements, and the reported amounts of additions
     to and deductions from net assets during the reporting period. Actual
     results could differ from those estimates.



                                      -7-
<PAGE>   12
     INVESTMENT VALUATION AND INCOME RECOGNITION - The Plan's investments are
     valued at fair value, except for its investment contracts which are valued
     at contract value.

     Shares of registered investment companies are valued at quoted market
     prices which represent the net asset value of shares held by the Plan at
     year end. Quoted market prices for the value of the common shares of each
     company in the Telephone Equity Fund and the Diversified Telephone
     Portfolio are obtained on the basis of the closing price on the New York
     Stock Exchange on the year end date or, if no sales were made on that date,
     at the closing price on the New York Stock Exchange on the next preceding
     day on which sales were made.

     Participant notes receivable are valued at outstanding principal balance
     which approximates fair value.

     A general public market for SAIC's common stock does not exist; therefore,
     the fair value of the common stock is determined pursuant to a stock price
     formula and valuation process which includes an appraisal prepared by an
     independent appraisal firm. Periodic determinations of fair value of the
     common stock are made by the SAIC Board of Directors, with the assistance
     of the independent appraisal firm. The SAIC Board of Directors reserves the
     right to alter the formula. On August 31, 1999, SAIC effected a
     four-for-one stock split payable in the form of a stock dividend. All share
     and per share information for SAIC's Class A Common Stock have been
     retroactively restated in these financial statements to reflect this split.

     The gains or losses realized on distributions of investments and the
     increases or decreases in unrealized appreciation are calculated as the
     difference between the current fair value and the fair value of the
     investments at the beginning of the year, or purchase price if purchased
     during the year. As of December 31, 1999, the fair value of SAIC's Class A
     Common Stock was $19.99 per share and the Plan held approximately 61,384
     shares.

     It is the policy of the Company to keep the SAIC Common Stock Fund invested
     primarily in common stock, except for estimated reserves for use in
     distributions and investment exchanges by participants. Such reserves are
     invested in the Vanguard Prime Money Market fund. If reserves in the SAIC
     Common Stock Fund are less than the amount required at any given time to
     make required distributions and investment changes, investment exchanges
     out of the SAIC Common Stock Fund by participants may have to be deferred.

     Purchases and sales of securities are reflected as of the trade date.
     Investments are valued on a daily basis. Dividend income is recorded on the
     ex-dividend date. Interest earned on investments is recorded on the accrual
     basis.

     BENEFIT PAYMENTS - Benefits are recorded when paid.

     PLAN TERMINATION - The Company intends to continue the Plan indefinitely,
     but reserves the right to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions of ERISA. In the event of the
     termination of the Plan, participants would become fully vested in their
     accounts; Company contributions would not be subject to forfeiture.

<PAGE>   13
     ADOPTION OF NEW ACCOUNTING PRONOUNCEMENT - On September 15, 1999 the
     Accounting Standards Executive Committee issued Statement of Position 99-3
     "Accounting for Defined Contribution Benefit Plan Investments and Other
     Disclosure Matters" ("SOP 99-3"), which eliminates the previous
     requirements for a defined contribution plan to present investments by
     general type for participant directed investments in the statement of net
     assets available for plan benefits, total number of units and the net asset
     value per unit during the period. SOP 99-3 is effective for plan years
     beginning after December 15, 1999, however, early adoption is encouraged.
     The Plan elected to early adopt the provisions of SOP 99-3 for the year
     ended December 31, 1999 and the prior year financial statements have been
     restated to conform with the current year presentation.

3.   INVESTMENTS

     Investments are summarized in the following schedule. Investments that
     represent five percent or more of the Plan's net assets are separately
     identified.

5.   INVESTMENT CONTRACTS WITH INSURANCE COMPANIES

      The Plan maintains investments in fully benefit-responsive investment
      contracts with a number of insurance companies and banks. (Benefit
      responsiveness is the extent to which contract terms permit and require
      withdrawals at contract value for benefit payments, loans, or transfers to
      other investment options offered to the participants by the Plan). The
      accounts are credited with earnings of the underlying investments
      (principally bank certificates of deposit, and other fixed income
      products) and charged for Plan withdrawals and administrative expenses.
      The contracts are included in the financial statements at contract value,
      which approximates fair value, as reported to the Plan by the respective
      provider.



                                      -10-
<PAGE>   15

      Contract value represents contributions made under the contract, plus
      earnings, less plan withdrawals and administrative expenses. See the
      supplemental schedule for a complete list of all contracts held in the
      fund.

      Approximately 39 percent and 27 percent of total net assets at December
      31, 1999 and 1998, respectively, were invested in investment contracts.
      These contracts are subject to credit risk. If any of the companies fail
      to perform on the contracts held, the asset value of the Interest Income
      Fund, and therefore the Plan, could be adversely impaired.

6.   PARTIES-IN-INTEREST


      Transactions involving cash, securities or assets of the Company, the
      Trustee or other affiliated persons are considered to be party-in-interest
      transactions under Section 2520.103-10 of the Department of Labor Rules
      and Regulations for Reporting and Disclosure. Reportable party-in-interest
      transactions for the years ended December 31, 1999 and 1998 are summarized
      as follows:

     Certain Plan investments are investment funds; and are shares of mutual
     funds managed by The Vanguard Group. Vanguard Fiduciary Trust Company is
     the trustee as defined by the Plan, and therefore these transactions
     qualify as party-in-interest.

     There were no known prohibited transactions with known parties in interest
     as defined in ERISA Section 3(14) and regulations thereunder, including
     those transactions set forth in ERISA Sections 406 and 407(a) and Internal
     Revenue Code Section 4975(c). There was no known relationship in which The
     Vanguard Fiduciary Trust Company had any direct or indirect financial
     interest which would affect its capacity to perform the necessary
     calculations.

     Fees paid by the Plan for administrative expenses and investment management
     services amounted to $4 and $3 for 1999 and 1998, respectively. All other
     Plan expenses are paid by the Company.


7.   TAX STATUS

     The Internal Revenue Service has determined and informed the Company by
     letter date February 24, 1999 that the Plan and related trust are designed
     in accordance with applicable sections of the Internal Revenue Code (the
     "Code"). The Plan Administrator and the Plan's counsel believe that the
     Plan is currently being operated in compliance with the applicable
     requirements of the Code. Therefore, no provision for income taxes has been
     included in the Plan's financial statements.

INDEPENDENT AUDITORS REPORT

To the Trustees and Participants of the
Telcordia Technologies Savings Plan for Salaried Employees
Morristown, New Jersey


We have audited the accompanying statements of net assets available for plan
benefits of Telcordia Technologies Savings Plan for Salaried Employees (the
"Plan") as of December 31, 1999, and the related statement of changes in net
assets available for plan benefits for the year then ended. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for plan benefits of the Plan as of December
31, 1999, and the changes in net assets available for plan benefits for the year
then ended in conformity with generally accepted accounting principles in the
United States of America. Our audit was conducted for the purpose of forming an
opinion on the basic financial statements taken as a whole. The supplemental
schedule listed in the Table of Contents is presented for the purpose of
additional analysis and is not a required part of the basic financial
statements, but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The supplemental schedule is the
responsibility of the Plan's management. Such supplemental schedule has been
subjected to the auditing procedures applied in our audit of the basic financial
statements and, in our opinion, is fairly stated in all material respects when
considered in relation to the basic financial statements taken as a whole.

                        REPORT OF INDEPENDENT ACCOUNTANTS



To the Participants and the Administrative Committee
of the Bell Communications Research Savings Plan for Salaried Employees


In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Bell Communications Research Savings Plan for Salaried Employees (the
"Plan") at December 31, 1998, and the changes in net assets available for
benefits for the year ended December 31, 1998, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
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 audit provides a
reasonable basis for the opinion expressed above. We have not audited the
financial statements of the Bell Communications Research Savings Plan for
Salaried Employees for any period subsequent to December 31, 1998.

TELCORDIA TECHNOLOGIES
SAVINGS PLAN FOR SALARIED EMPLOYEES
(FORMERLY BELL COMMUNICATIONS RESEARCH SAVINGS PLAN FOR SALARIED
EMPLOYEES)


NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1999 AND 1998
(DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
- --------------------------------------------------------------------------------


1.   DESCRIPTION OF PLAN

     The Telcordia Technologies Savings Plan for Salaried Employees (formerly
     the Bell Communications Research Savings Plan for Salaried employees) (the
     "Plan") was established by Telcordia Technologies, Inc. ("Telcordia" or the
     "Company") to provide a convenient way for salaried employees to save on a
     regular and long term basis. On November 14, 1997, the Company was sold to
     Science Applications International Corporation ("SAIC"). Prior to the sale,
     the Company was owned by the Regional Bell Operating Companies ("RBOC's").

     Effective March 9, 1999, the Company changed its name to Telcordia
     Technologies.

     Effective March 17, 1999, the name of the Plan was changed to Telcordia
     Technologies Savings and Security Plan.

     The following description of the Plan provides only general information.
     Participants should refer to the Plan Prospectus for a more complete
     description of the Plan's provisions.

     GENERAL - The Plan is a defined contribution plan covering all salaried
     employees of the Company who have one month of service. It is subject to
     the provisions of the Employee Retirement Income Security Act of 1974
     ("ERISA").

     CONTRIBUTIONS - Each year, participants may contribute up to 16 percent of
     pretax annual compensation, as defined in the Plan. Participants may also
     contribute amounts representing distributions from other qualified defined
     benefit or contribution plans. After one year of service, the Company will
     make a matching contribution equal to 70 percent of the first 6 percent of
     compensation that a participant contributes to the Plan. In addition, after
     one year of service, the Company will make an annual discretionary
     contribution of a 1/2 percent of compensation on behalf of each
     participant. The Company's discretionary contributions are deposited into
     the SAIC Stock Purchase Fund until the following quarterly trade date and
     then into the SAIC Non Exchangeable Stock Fund. The Company's discretionary
     contributions are made during the first quarter for participant earnings of
     the previous calendar year. The Company's discretionary contributions are
     immediately vested. The Company's matching contributions are invested 50
     percent in the SAIC Non Exchangeable Stock Fund and 50 percent are invested
     in accordance with each participant's directed allocation. Contributions
     are subject to certain IRS limitations.

     PARTICIPANT ACCOUNTS - Each participant's account is credited with the
     participant's contribution and allocations of the Company's contribution
     and fund earnings, and each participant's account is charged with an
     allocation of administrative expenses. Allocations are based on participant
     earnings or account balances, as defined. The benefit to which a
     participant is entitled is the benefit that can be provided from the
     participant's vested account.



                                      -5-
<PAGE>   10

     VESTING - Participants are immediately vested in their contributions and
     the Company's discretionary contributions, plus actual earnings thereon.
     Vesting in the Company's matching contributions plus actual earnings
     thereon are based on years of continuous service. A participant is fully
     vested after five years of credited service.

     PARTICIPANT LOANS RECEIVABLE - Participants may borrow from their fund
     accounts a minimum of $1 up to a maximum of the lesser of (a) $50 less the
     participant's highest outstanding loan balance during the preceding one
     year period; or (b) 50 percent of their vested account balance.
     Additionally, loans may not exceed the vested value of the participant's
     Plan account less their vested amounts in the SAIC Stock Fund within the
     Plan. Loan transactions are treated as a transfer to (from) the investment
     fund from (to) the Loan Fund. Loan terms range from 12 to 56 months. The
     loans are secured by the balance in the participant's account and bear
     interest at a rate commensurate with local prevailing rates as determined
     quarterly by the Plan Administrator. Interest rates ranged from 9.50 to
     8.75 percent during 1999 and 1998. Principal and interest is paid ratably
     through monthly payroll deductions.

     PAYMENT OF BENEFITS - On termination of service other than by death, a
     participant may elect to receive either a lump-sum amount equal to the
     value of the participant's vested interest in his or her account, or annual
     installments not to exceed the life expectancy of the participant and
     spouse, if applicable. For termination of service due to death, a
     beneficiary may receive the value of the vested interest in his or her
     account as a lump-sum distribution, or in two annual installments, if the
     participant has so elected.

     FORFEITED ACCOUNTS - Forfeited accounts are used to reduce future Company
     contributions. Company contributions were reduced by $889 and $168 in 1999
     and 1998, respectively.

     INVESTMENT OPTIONS - The Plan is comprised of the following investments:

       -  VANGUARD TOTAL BOND MARKET INDEX FUND: This participant directed fund
          invests in United States treasury obligations, federal agency mortgage
          backed obligations and investment grade corporate obligations.

       -  VANGUARD EXPLORER FUND: This participant directed fund
          invests in the common stock of a diversified group of small
          capitalization companies.

       -  VANGUARD 500 INDEX FUND: This participant directed fund invests in all
          of the 500 stocks that make up the Standard & Poor's 500 Composite
          Stock Price Index.

       -  VANGUARD INTERNATIONAL GROWTH FUND: This participant
          directed fund invests in the common stocks of companies
          based outside of the United States.

       -  VANGUARD / PRIMECAP FUND: This participant directed fund
          invests in the common stock of medium capitalization
          companies.

       -  VANGUARD / WELLINGTON FUND: This participant directed fund invests
          approximately 65 percent of its assets in common stocks and the
          remaining 35 percent in bonds.

          invests in the common stock of large capitalization
          companies.



                                      -6-
<PAGE>   11
       -  SAIC EXCHANGEABLE STOCK FUND: This fund invests primarily in SAIC
          class A common stock and is participant directed to the extent that
          participant contributions were used to purchase SAIC stock. Effective
          October 1999, the company announced the closing of SAIC stock funds to
          all inactive participants of the plan. Inactive participants would
          have until July 2000 to move assets held in these funds. Any remaining
          funds will be moved to the interest income fund.

       -  SAIC NON EXCHANGEABLE STOCK FUND: This is a non-participant directed
          fund created to invest 50% of the Company's matching contributions and
          the Company's annual discretionary contributions in SAIC class A
          common stock. Effective October 1999, the company announced the
          closing of SAIC stock funds to all inactive participants of the plan.
          Inactive participants would have until July 2000 to move assets held
          in these funds. Any remaining funds will be moved to the interest
          income fund.

       -  The SAIC STOCK PURCHASE FUND is not a participant directed investment
          option; it is a temporary holding fund designed to hold respective
          participant and Company contributions until the following SAIC common
          stock quarterly trade date. Pending the quarterly trade, the
          respective contributions are invested in the Vanguard Money Market
          Reserves Portfolio.

       -  TELCORDIA TECHNOLOGIES, INC. - INTEREST INCOME FUND: This participant
          directed fund invests primarily in investment contracts issued by
          insurance companies and banks.

       -  TELCORDIA TECHNOLOGIES, INC. - DIVERSIFIED TELEPHONE PORTFOLIO STOCK
          FUND: This fund invests primarily in common stock and has been frozen
          to new participant directed contributions since 1984.

       -  TELCORDIA TECHNOLOGIES, INC. - TELEPHONE EQUITY FUND STOCK FUND: This
          fund invested in the common stock of the RBOC's. Upon the sale of the
          Company to SAIC, the fund was frozen to new participant directed
          contributions, and then closed on January 31, 1999. Any remaining
          balances that were held in Telephone Equity Fund were automatically
          transferred to the Interest Income Fund on February 1, 1999.

     Effective January 1, 2000, the Plan was amended to allow two new investment
     options, the Vanguard US Growth Fund and the Vanguard Extended Market Fund.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF ACCOUNTING - The accompanying financial statements have been
     prepared on the accrual basis of accounting in accordance with generally
     accepted accounting principles.

     USE OF ESTIMATES - The preparation of financial statements in conformity
     with generally accepted accounting principles requires management to make
     significant estimates and assumptions that affect the reported amounts of
     assets, liabilities and disclosures of contingent assets and liabilities at
     the date of the financial statements, and the reported amounts of additions
     to and deductions from net assets during the reporting period. Actual
     results could differ from those estimates.



                                      -7-
<PAGE>   12
     INVESTMENT VALUATION AND INCOME RECOGNITION - The Plan's investments are
     valued at fair value, except for its investment contracts which are valued
     at contract value.

     Shares of registered investment companies are valued at quoted market
     prices which represent the net asset value of shares held by the Plan at
     year end. Quoted market prices for the value of the common shares of each
     company in the Telephone Equity Fund and the Diversified Telephone
     Portfolio are obtained on the basis of the closing price on the New York
     Stock Exchange on the year end date or, if no sales were made on that date,
     at the closing price on the New York Stock Exchange on the next preceding
     day on which sales were made.

     Participant notes receivable are valued at outstanding principal balance
     which approximates fair value.

     A general public market for SAIC's common stock does not exist; therefore,
     the fair value of the common stock is determined pursuant to a stock price
     formula and valuation process which includes an appraisal prepared by an
     independent appraisal firm. Periodic determinations of fair value of the
     common stock are made by the SAIC Board of Directors, with the assistance
     of the independent appraisal firm. The SAIC Board of Directors reserves the
     right to alter the formula. On August 31, 1999, SAIC effected a
     four-for-one stock split payable in the form of a stock dividend. All share
     and per share information for SAIC's Class A Common Stock have been
     retroactively restated in these financial statements to reflect this split.

     The gains or losses realized on distributions of investments and the
     increases or decreases in unrealized appreciation are calculated as the
     difference between the current fair value and the fair value of the
     investments at the beginning of the year, or purchase price if purchased
     during the year. As of December 31, 1999, the fair value of SAIC's class A
     common stock was $19.99 per share and the Plan held approximately
     14,262,760 shares.

     It is the policy of the Company to keep the SAIC Common Stock Fund invested
     primarily in common stock, except for estimated reserves for use in
     distributions and investment exchanges by participants. Such reserves are
     invested in the Vanguard Prime Money Market fund. If reserves in the SAIC
     Common Stock Fund are less than the amount required at any given time to
     make required distributions and investment changes, investment exchanges
     out of the SAIC Common Stock Fund by participants may have to be deferred.

     Purchases and sales of securities are reflected as of the trade date.
     Investments are valued on a daily basis. Dividend income is recorded on the
     ex-dividend date. Interest earned on investments is recorded on the accrual
     basis.

     BENEFIT PAYMENTS - Benefits are recorded when paid.

     PLAN TERMINATION - The Company intends to continue the Plan indefinitely,
     but reserves the right to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions of ERISA. In the event of the
     termination of the Plan, participants would become fully vested in their
     accounts; Company contributions would not be subject to forfeiture.



                                      -8-
<PAGE>   13
     ADOPTION OF NEW ACCOUNTING PRONOUNCEMENT - On September 15, 1999 the
     Accounting Standards Executive Committee issued Statement of Position 99-3
     "Accounting for Defined Contribution Benefit Plan Investments and Other
     Disclosure Matters" ("SOP 99-3"), which eliminates the previous
     requirements for a defined contribution plan to present investments by
     general type for participant directed investments in the statement of net
     assets available for plan benefits, total number of units and the net asset
     value per unit during the period. SOP 99-3 is effective for plan years
     beginning after December 15, 1999, however, early adoption is encouraged.
     The Plan elected to early adopt the provisions of SOP 99-3 for the year
     ended December 31, 1999 and the prior year financial statements have been
     restated to conform with the current year presentation.

3.   INVESTMENTS

     Investments are summarized in the following schedule. Investments that
     represent five percent or more of the Plan's net assets are separately
     identified.

5.   INVESTMENT CONTRACTS WITH INSURANCE COMPANIES

     The Plan maintains investments in fully benefit-responsive investment
     contracts with a number of insurance companies and banks. (Benefit
     responsiveness is the extent to which contract terms permit and require
     withdrawals at contract value for benefit payments, loans, or transfers to
     other investment options offered to the participants by the Plan). The
     accounts are credited with earnings of the underlying investments
     (principally bank certificates of deposit, and other fixed income products)
     and charged for Plan withdrawals and administrative expenses. The contracts
     are included in the financial statements at contract value, which
     approximates fair value, as reported to the Plan by the respective
     provider.

     Contract value represents contributions made under the contract, plus
     earnings, less plan withdrawals and administrative expenses. See the
     supplemental schedule for a complete list of all contracts held in the
     fund.

     Approximately 20 percent and 18 percent of total net assets at December 31,
     1999 and 1998, respectively, were invested in investment contracts. These
     contracts are subject to credit risk. If any of the companies fail to
     perform on the contracts held, the asset value of the Interest Income Fund,
     and therefore the Plan, could be adversely impaired.

     Certain Plan investments are investment funds; and are shares of mutual
     funds managed by The Vanguard Group. Vanguard Fiduciary Trust Company is
     the trustee as defined by the Plan, and therefore these transactions
     qualify as party-in-interest.

     There were no known prohibited transactions with known parties in interest
     as defined in ERISA Section 3(14) and regulations thereunder, including
     those transactions set forth in ERISA Sections 406 and 407(a) and Internal
     Revenue Code Section 4975(c). There was no known relationship in which The
     Vanguard Fiduciary Trust Company had any direct or indirect financial
     interest which would affect its capacity to perform the necessary
     calculations.

     Fees paid by the Plan for administrative expenses and investment management
     services amounted to $225 and $264 for 1999 and 1998, respectively. All
     other Plan expenses are paid by the Company.

7.   TAX STATUS

     The Internal Revenue Service has determined and informed the Company by
     letter date February 24, 1999 that the Plan and related trust are designed
     in accordance with applicable sections of the Internal Revenue Code (the
     "Code"). The Plan Administrator and the Plan's counsel believe that the
     Plan is currently being operated in compliance with the applicable
     requirements of the Code. Therefore, no provision for income taxes has been
     included in the Plan's financial statements.
