PROSPECTUS
                                       
                   3,000,000 SHARES OF CLASS A COMMON STOCK
                SCIENCE APPLICATIONS INTERNATIONAL CORPORATION
                                          
     Science Applications International Corporation ("SAIC" or the "Company") 
has registered 3,000,000 shares of its Class A Common Stock, par value $.01 
per share (the "Class A Common Stock"), which may be offered from time to 
time by this Prospectus in connection with one or more acquisition 
transactions (each, an "Acquisition").

     The consideration to be offered by the Company in Acquisitions may 
consist of shares of the Class A Common Stock ("Acquisition Shares"), cash, 
promissory notes, the assumption of liabilities, commitments to make future 
capital contributions to the business to be acquired or any combination 
thereof. Acquisitions may be accomplished by one or more methods, including 
but not limited to the acquisition by the Company of stock, partnership 
interests, limited liability company interests or assets of a business or 
entity to be acquired or the merger or consolidation of such corporation or 
entity with the Company or a subsidiary of the Company. The amount and type 
of consideration to be offered and the other terms of each Acquisition will 
be determined by negotiations between the Company and the owners or 
controlling persons of the business or assets to be acquired and will be set 
forth in a definitive agreement among such parties governing such 
Acquisition. The Company may be required to provide information (or further 
information) by means of a post-effective amendment to the Registration 
Statement or supplement to this Prospectus once the required information 
concerning an Acquisition and the company to be acquired pursuant thereto are 
known to the Company.

     This Prospectus, as amended or supplemented if appropriate, has also 
been prepared for use by persons who will receive shares issued by the 
Company in Acquisitions and who wish to offer and sell such shares, on terms 
then obtainable, in transactions in which they may be deemed underwriters 
within the meaning of the Securities Act of 1933, as amended (the "Securities 
Act"). Any profits realized on such sales by such persons may be regarded as 
underwriting compensation under the Securities Act. See "Resales by 
Affiliates of Acquired Companies." In addition, if permitted by law, the 
Company may pay finders' fees from time to time in connection with specific 
Acquisitions. Finders' fees may be in the form of cash but will not be paid 
in shares of the Class A Common Stock offered hereby. Any person receiving 
any such fees may be deemed underwriters within the meaning of the Securities 
Act, and such fees may be regarded as underwriting compensation under the 
Securities Act. Other than as provided above, the Company does not expect to 
pay underwriting commissions or discounts in connection with this Offering.
     
     All of the Acquisition Shares will be subject to certain restrictions 
(including restrictions on their transferability) set forth in the Company's 
Restated Certificate of Incorporation (the "Certificate of Incorporation") 
and may be subject to certain contingencies. See "Description of Class A 
Common Stock --Common Stock -- Restrictions on Class A Common Stock." SEE 
"RISK FACTORS" ON PAGES 3 TO 7 FOR A DESCRIPTION OF THIS AND CERTAIN OTHER 
RISKS THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.

                                  RISK FACTORS
                                          
     Prior to purchasing the Class A Common Stock offered in the Prospectus, 
purchasers should carefully consider all of the information contained in the 
Prospectus and in particular should carefully consider the following factors:

CONCENTRATION OF REVENUE

     Revenues generated from the sale of the Company's Technical Services and 
Products (as such terms are defined on page 7) to the U.S. Government as a 
prime contractor or subcontractor accounted for 66%, 79%, and 83% of revenues 
in fiscal years 1998, 1997, and 1996, respectively. U.S. Government spending 
has declined in recent years, and the current Congress and presidential 
administration have indicated that they intend to further reduce U.S. 
Government spending. In addition, revenues from the U.S. Government continues 
to shift toward lower cost service type contracts. The loss of a substantial 
amount of government business could have a material adverse effect on the 
Company's results of operations and financial condition. In addition, the 
Company's wholly-owned subsidiary, Bell Communications Research, Inc. 
("Bellcore"), has historically derived substantially all of its revenues from 
the Regional Bell Operating Companies (the "RBOCs"). Although the Company has 
made progress in its efforts to diversify its business, it remains heavily 
dependent upon business with the U.S. Government and with the RBOCs, and 
there can be no assurances that the Company will be successful in expanding 
its customer base or that any new customers will place orders for the 
Company's Technical Services or Products in amounts comparable to those of 
the U.S. Government or the RBOCs. See "The Company."

POTENTIAL IMPACT OF ACQUISITION OF BELLCORE

     On November 14, 1997, pursuant to a definitive agreement, the Company 
completed its acquisition of Bellcore, a global provider of software, 
engineering and consulting services, advanced research and development, 
technical training and other services to the telecommunications industry. As 
of January 31, 1998, Bellcore had approximately 5,400 employees and annual 
revenues of approximately $1 billion.  The acquisition resulted in a 
substantial growth in both the employee base and commercial revenues of the 
Company. The Company financed a portion of the purchase price of Bellcore 
with debt financing. Such growth and additional debt may place a significant 
strain on the Company's management, operational and financial resources. 
There can be no assurance that the Company will be able to effectively manage 
the expansion of its operations or that the Company's systems, procedures or 
controls will be adequate to support the integration of the acquired 
business. Any inability to effectively integrate the acquired business or 
manage the growth could have a material adverse effect on the Company's 
results of operations and financial condition.

DEPENDENCE ON ACQUISITIONS FOR GROWTH

     A significant portion of the growth in the Company's revenues in recent 
years has been achieved through acquisitions of businesses that complement 
the Company's Technical Services and Products. Although the Company intends 
to make additional acquisitions in the future, the number and size of the 
acquisitions that the Company can complete may be limited due to the 
Company's acquisition of Bellcore. In addition, while the Company has been 
successful in identifying and consummating acquisitions in the past, there 
can be no assurance that it will be able to continue to make such 
acquisitions in the future at prices that it considers reasonable or, if the 
acquisitions are consummated, that the Company will be able to integrate the 
acquired businesses without adversely affecting the Company's results of 
operations and financial condition.

<PAGE>

YEAR 2000 COMPLIANCE

     The Company has commenced, and in some cases finalized, the evaluation 
of computer systems to ensure its operations will not be adversely impacted 
by Year 2000 software problems. The evaluation determined that certain 
portions of the Company's software and systems require modification or 
replacement. If the necessary modifications to existing software and 
conversions to new software are not made, or are not completed timely, the 
Year 2000 issue could have a material adverse impact on the Company's 
consolidated financial position, results of operations, cash flow or its 
ability to conduct business. In addition, the Company has initiated 
communications with its critical service providers, suppliers and vendors to 
determine the extent to which the Company is vulnerable to those third 
parties' failure to remediate their own Year 2000 issues. There can be no 
assurance that such failure would not have a material adverse effect on the 
Company's consolidated financial position, results of operations, cash flows 
or its ability to conduct business. Furthermore, the Company has implemented 
an ongoing program to assess its exposure with respect to its products and 
services. To date, no matters have come to the attention of the Company's 
management that would have a material adverse effect on the Company's 
consolidated financial position, results of operations, cash flows or its 
ability to conduct business; however, there can be no assurance that the 
Company will not be subject to material liability claims in the future.

     The Company's assessment of the Year 2000 issue, including the costs of 
the project and the timing of completion are based on management's best 
estimates and input from third party customers, service providers, suppliers 
and vendors. These estimates were derived using numerous assumptions about 
future events, including the continued availability of certain resources, 
third party modification plans and other factors. However, there can be no 
assurance that these estimates will be achieved and actual results could 
differ materially from those anticipated. See 1998 10-K, Item 7, 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations."

ABSENCE OF A PUBLIC MARKET

     There is no public market for the Common Stock. The Limited Market (as 
such term is defined on page 9) 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. The Company and the 
trustees and agents of the Company's and certain of its subsidiaries' 
employee benefit plans are currently authorized, but not obligated, to 
purchase shares of Class A Common Stock in the Limited Market on any Trade 
Date, but only if and to the extent that they, in their discretion, determine 
to make such purchases. To the extent that purchases by such trustees, 
agents, or the Company are not sufficient, the ability of stockholders to 
resell their shares in the Limited Market will likely be adversely affected. 
In each trade occurring during the last two fiscal years, all shares of Class 
A Common Stock offered for sale in the Limited Market were matched with buy 
orders and sold in the Limited Market. No assurance, however, can be given 
that a stockholder desiring to sell all or a portion of his or her shares of 
Class A Common Stock in any trade will be able to do so. See 1998 10-K, Item 
5, "Market for Registrant's Common Equity and Related Stockholder Matters-- 
The Limited Market."

CLASS A COMMON STOCK PRICE DETERMINED BY BOARD OF DIRECTORS

     The offering price and the price at which the Class A Common Stock 
trades in the Limited Market are not, and subsequent prices (the "Formula 
Price") will not be, determined by the operation of a market of bargaining 
buyers and sellers. Instead, the Formula Price is a value established by the 
Board of Directors pursuant to a formula adopted by the Board of Directors 
(the "Formula") and valuation process which the Board of Directors believes 
represents a fair market value. The Board of Directors generally has broad 
discretion to modify the Formula. The Formula was last modified in April 
1998. The Formula does not specifically include variables reflecting all 
relevant financial and valuation criteria. The mechanical application of the 
Formula, assuming a constant market factor that is set by the Board of 
Directors, tends to smooth the impact on the stock 


                                       4

<PAGE>


price of quarterly fluctuations in the Company's operating results because 
the Formula takes into account the net income of the Company for the four 
preceding quarters. See 1998 10-K, Item 5, "Market for Registrant's Common 
Equity and Related Stockholder Matters--Price Range of Class A Common Stock 
and Class B Common Stock."

POSSIBLE VOLATILITY OF STOCK PRICE

     The Formula Price of the Class A Common Stock could be subject to 
greater fluctuations in the future than it has experienced in the past. The 
increased volatility is expected to result from a number of factors, 
including (i) plans to continue to increase the proportion of the Company's 
business involving private sector customer, international customers and 
information technology and the greater stock price volatility associated with 
companies in such business areas, (ii) the financial leverage impact of 
current and any future debt levels of the Company as debt financing is used 
to finance acquisitions and for other purposes, (iii) other equity 
transactions that the Company may pursue, including public offerings of 
securities of the Company's subsidiaries or affiliates, and (iv) the 
volatility of the stock price of the Class A Common Stock of Network 
Solutions, Inc. ("NSI"), a publicly-traded security of a majority-owned 
subsidiary of the Company, and its impact on the Formula Price. As of March 
13, 1998, the Company owned 100% of the outstanding Class B Common Stock of 
NSI, representing approximately 76% of the combined outstanding common stock 
of NSI. The NSI Class B Common Stock is convertible into NSI Class A Common 
Stock, subject to certain limitations.

NO ASSURANCES REGARDING FUTURE RETURNS

     There can be no assurance that the Class A Common Stock will in the 
future provide returns comparable to historical returns or that the Formula 
Price will not decline. See 1998 10-K, Item 5, "Market for Registrant's 
Common Equity and Related Stockholder Matters--Price Range of Class A Common 
Stock and Class B Common Stock."

COMPETITION

     The businesses in which the Company is engaged are highly competitive. 
The Company's competitors include larger organizations with substantially 
greater financial resources and larger technical staffs, smaller, more highly 
specialized entities, the U.S. Government's own in-house capabilities and 
federal non-profit contract research centers. The Company's continued success 
is dependent upon its ability to provide superior service and performance on 
a cost-effective basis. See 1998 10-K, Item 1, "Business--Competition."

EARLY TERMINATION OF GOVERNMENT CONTRACTS

     Many of the U.S. Government programs in which the Company participates 
as a contractor or subcontractor may extend for several years; however, such 
programs are normally funded on an annual basis. All U.S. Government 
contracts and subcontracts may be modified, curtailed or terminated at the 
convenience of the government. Modification, termination or curtailment of 
major programs or contracts of the Company could have a material adverse 
effect on the Company's results of operations and financial condition. 
Although such contract and program modifications, terminations or 
curtailments have not had a material adverse effect on the Company in the 
past, no assurance can be given that they will not have such an effect in the 
future.

POTENTIAL GOVERNMENT INQUIRIES AND INVESTIGATIONS

     The Company is from time to time subject to certain U.S. Government 
inquiries and investigations of its business practices. No assurance can be 
given that any such inquiry or investigation would not have a material 
adverse effect on the Company's results of operations and financial condition.


                                       5

CONTRACT REVENUES SUBJECT TO AUDITS BY GOVERNMENT AGENCIES

     Contract costs for services or products supplied to the U.S. Government, 
including allocated indirect costs, are subject to audit and adjustments by 
negotiations between the Company and U.S. Government representatives. 
Substantially all of the Company's indirect contract costs have been agreed 
upon through the fiscal year ended January 31, 1997. Contract revenues for 
subsequent years have been recorded in amounts which are expected to be 
realized upon final settlement. However, no assurance can be given that 
audits and adjustments for subsequent years will not result in decreased 
revenues or profits for those years.

FIXED PRICE CONTRACT EXPOSURE

     During the fiscal years ended January 31, 1998, 1997 and 1996, 
approximately 32%, 20% and 16%, respectively, of Technical Services revenues 
were from firm fixed-price type contracts, while the majority of Products 
revenues in these three years were derived from such contracts. Because the 
Company assumes the risk of performing a firm fixed-price contract at the 
stipulated price, the failure to accurately estimate ultimate costs or to 
control costs during performance of the work could result, and in some 
instances has resulted, in reduced profits or losses for particular firm 
fixed-price contracts.

AT RISK CONTRACT COSTS

     Any costs incurred by the Company prior to the execution of a contract 
or contract amendment are incurred at the Company's risk, and it is possible 
that such costs will not be reimbursed by the customer. Unbilled receivables 
in this category which were included in Technical Services and Products 
revenues at January 31, 1998 were $14,583,000 and $664,000, respectively. The 
Company expects to recover substantially all such costs; however, no 
assurance can be given that the contracts or contract amendments will be 
received or that the related costs will be recovered.

RISKS ASSOCIATED WITH INTERNATIONAL SALES AND CURRENCY EXCHANGES

     The Company conducts a portion of its business outside of the U.S. in 
transactions denominated in foreign currencies. As a result, the Company is 
exposed to fluctuations in exchange rates which could result in losses, and 
in turn, could adversely impact the Company's results of operations. Under 
the Company's current foreign currency management policy, the Company may use 
forward foreign currency exchange rate contracts to hedge against movements 
in exchange rates for contracts executed in foreign currencies. However, the 
Company generally does not hedge its exchange rate risks for its foreign 
subsidiaries, which generally conduct business in currencies other than the 
U.S. Dollar. Significant fluctuations in exchange rates in such countries 
could have a material adverse effect on the Company's results of operations. 
This risk may be significant for entities such as INTESA (a Venezuelan joint 
venture in which the Company has a 60% ownership interest) that operate in 
highly inflationary economies. To date, losses resulting from exchange rate 
fluctuations have not had a material adverse impact on the Company's results 
of operations; however, there can be no assurance that the Company's future 
results of operations will not be materially impacted by exchange rate 
fluctuations.

NO CASH DIVIDENDS

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

RESTRICTIONS ON CLASS A COMMON STOCK

     Certain of the shares of Class A Common Stock presently outstanding are, 
and all shares of Class A Common Stock offered hereby will be, subject to 
certain restrictions (including a right of first refusal and a right of 
repurchase upon termination of employment or affiliation and other 
restrictions on their transferability) set forth in the Company's Certificate 
of Incorporation.

DEPENDENCE UPON KEY PERSONNEL

     The Company's success will depend upon the continued contributions of its
founder, J.R. Beyster, its officers and key personnel, the loss of which could
materially adversely affect the Company's operations. The Company has not
generally entered into long-term employment contracts with its officers and key
employees. In addition, the Company does not maintain "key man" life insurance
for its officers or key employees.

ATTRACTION AND RETENTION OF SKILLED EMPLOYEES

     The highly technical and complex services and products provided by the 
Company are dependent upon the availability of professional, administrative 
and technical personnel having high levels of training and skills. Because of 
the Company's growth and competitive business environment, it has become more 
difficult to meet all of the Company's needs for such employees in a timely 
manner. Competition for such personnel is intense and competitors often 
employ aggressive tactics to recruit key employees. The Company intends to 
continue to devote significant resources to recruit and retain qualified 
employees; however, no assurance can be given that the Company will be able 
to attract and retain such employees on acceptable terms. Any failure to do 
so could have a material adverse effect on the Company's operations.

ANTI-TAKEOVER EFFECTS

     Consistent with and in furtherance of the Company's employee ownership 
philosophy, certain provisions of the Company's Certificate of Incorporation 
and Bylaws may discourage, delay, or prevent attempts to acquire control of 
the Company that are not approved by the Company's Board of Directors. The 
provisions may, individually or collectively, have the effect of discouraging 
takeover attempts that some stockholders might deem to be in their best 
interests, including tender offers in which stockholders might receive a 
premium for their shares over the Formula Price, as well as making it more 
difficult for individual stockholders or a group of stockholders to elect 
directors. See "Description of Class A Common Stock--Anti-Takeover Effects."

                                 THE COMPANY
                                          
     The Company provides diversified professional and technical services 
("Technical Services") and designs, develops and manufactures high-technology 
products ("Products"). The Company's Technical Services and Products have 
been primarily sold to departments and agencies of the U.S. Government, 
including the Department of Defense, Department of Energy, Department of 
Transportation, Department of Veterans Affairs, Environmental Protection 
Agency and National Aeronautics and Space Administration. The balance of the 
Company's revenues were attributable to the sales of Technical Services and 
Products to foreign, state and local governments, commercial customers and 
others. With the completion of the acquisition of Bellcore, the Company's 
revenues attributable to sales of Technical Services and Products to 
commercial customers are expected to increase substantially as a percentage 
of revenues. See "Risk Factors--Concentration of Revenue."

     The percentage of revenues attributable to Technical Services has 
increased since fiscal year 1996 while Products revenues have correspondingly 
decreased. The Company provides Technical Services primarily in the areas of 
"National Security," "Health," "Environment," "Energy," "Telecommunications," 
"Commercial 

                                      7


<PAGE>

Information Technology" and "Other Technical Services," the last of which 
includes the Company's transportation and space business areas. The 
percentage of Technical Services revenues attributable to National 
Security-related work has gradually declined since fiscal year 1996.

     A significant portion of the growth in the Company's revenues in recent 
years has been achieved through acquisitions of businesses that complement 
the Company's Technical Services. Acquisitions of businesses in fiscal years 
1998 and 1997 were primarily financed with cash and in fiscal year 1996 were 
made primarily with issuance of Class A Common Stock. On November 14, 
1997,pursuant to a definitive agreement, the Company completed its 
acquisition of Bellcore, a global provider of software, engineering and 
consulting services, advanced research and development, technical training 
and other services to the telecommunications industry. As of January 31, 
1998, Bellcore had approximately 5,400 employees and annual revenues of 
approximately $1 billion. The acquisition resulted in a substantial growth in 
both the employee base and commercial revenues of the Company. The Company 
financed a portion of the purchase price of Bellcore with debt financing. See 
"Risk Factors--Potential Impact of Acquisition of Bellcore " and 
"--Dependence on Acquisitions for Growth."

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

                                 THE OFFERING
                                          
     The offering consists of up to 3,000,000 shares of Class A Common Stock 
which may be offered by the Company from time to time pursuant to this 
Prospectus in connection with one or more Acquisitions (the "Offering"). The 
consideration to be offered by the Company in Acquisitions may include 
Acquisition Shares, cash, promissory notes, the assumption of liabilities, 
commitments to make future capital contributions to the business to be 
acquired or any combination thereof. Acquisitions may be accomplished by one 
or more methods, including but not limited to the acquisition by the Company 
of stock, partnership interests, limited liability company interests or 
assets of a business or entity to be acquired or the merger or consolidation 
of such corporation or entity with the Company or a subsidiary of the 
Company. The amount and type of consideration to be offered and the other 
terms of each Acquisition will be determined by negotiations between the 
Company and the owners or controlling persons of the business or assets to be 
acquired and will be set forth in a definitive agreement among such parties 
governing such Acquisition (an "Acquisition Agreement"). The Company expects 
that, in most cases, the aggregate market value of the Acquisition Shares to 
be issued in connection with any Acquisition will be determined upon signing 
or closing of the Acquisition Agreement relating to such Acquisition (subject 
to post-closing adjustments, if any). Such Acquisition Shares may be issued 
in installments or subject to contingencies or vesting requirements. It is 
not expected that any individual who is an officer, director, employee or 
affiliate of SAIC or any of its subsidiaries will be receiving any shares of 
Class A Common Stock offered hereby.

     The Company's acquisition strategy is primarily to target companies or 
business operations that would add new or complementary technologies, 
capabilities or customers. In circumstances where it is financially 
attractive to the Company, the Company may also acquire companies or business 
operations involving existing capabilities or customers in order to increase 
its presence in the relevant markets.

     The Company anticipates that none of the Acquisitions will require the 
approval of the stockholders of SAIC. Therefore, under Delaware law, holders 
of the Class A Common Stock and the Class B Common Stock, par value $.05 per 
share (the "Class B Common Stock"), would not have any dissenters' rights 
with respect to any of the Acquisitions. Generally, to the extent that any 
Acquisition involves the sale of all or substantially all of the assets of 
the company to be acquired (the "Acquired Company") or the merger or 
consolidation of the 


                                       8

<PAGE>

Acquired Company with SAIC or a subsidiary of SAIC, such Acquisition would 
require the approval of the stockholders of the Acquired Company in 
accordance with the laws of the state of incorporation of the Acquired 
Company and/or its certificate or articles of incorporation. The availability 
of appraisal or similar rights to dissenting stockholders of the Acquired 
Company will also be a matter to be determined under the law of the state of 
incorporation of the Acquired Company and/or its certificate or articles of 
incorporation.

     The Offering will be conducted primarily through the efforts of the 
Company's management. No officer, director, employee or affiliate of the 
Company is expected to receive any direct or indirect compensation relating 
to the Offering, nor is any such person expected to have any material 
interest, direct or indirect, in any Acquisition under consideration by the 
Company. Under certain circumstances, persons who receive Acquisition Shares 
and who wish to offer and sell such shares, on terms then obtainable, may be 
deemed to be underwriters within the meaning of the Securities Act. In 
addition, if permitted by law, the Company may pay finders' fees from time to 
time in connection with specific Acquisitions. Finders' fees may be in the 
form of cash but will not be paid in shares of Class A Common Stock offered 
hereby. Any person receiving any such fees may be deemed underwriters within 
the meaning of the Securities Act and such fees may be regarded as 
underwriting compensation under the Securities Act. 

     The Company expects to account for the Acquisitions by the purchase 
method of accounting in which case the stock or assets acquired will be 
valued based on the fair market value of the consideration, including the 
Acquisition Shares, paid or payable therefor.

     The federal income tax consequences of Acquisitions are likely to differ 
as a function of the structure of each specific Acquisition, the terms of the 
governing Acquisition Agreement and other factors. Until each specific 
Acquisition is structured, it is not possible to determine the federal income 
tax consequences of such Acquisition to the Company, the Acquired Company or 
its stockholders. However, it is expected that no Acquisition will have 
significant federal income tax consequences to the Company. On the other 
hand, the federal income tax consequences to the Acquired Company or its 
stockholders may be significant. Therefore, before deciding whether to 
participate in or to approve, consent or otherwise authorize an Acquisition 
in which the Acquired Company or its stockholders would receive Acquisition 
Shares (in total or partial consideration thereof), the Acquired Company and 
each such stockholder should consult their own tax advisors as to the tax 
consequences of such transaction.
                                          
                 RESALES BY AFFILIATES OF ACQUIRED COMPANIES
                                          
     This Prospectus, as appropriately amended or supplemented, has also been 
prepared for use by those persons who may receive Acquisition Shares from the 
Company and who are deemed to control, be controlled by or under common 
control with the Acquired Company. Such persons (referred to under this 
caption as "Affiliates") may be entitled to offer and sell such Class A 
Common Stock, on terms then obtainable, under circumstances requiring the use 
of a Prospectus; provided, however, that no such Affiliate will be authorized 
to use this Prospectus for any offer or sale of such Class A Common Stock 
without first obtaining the consent of the Company. The Company may consent 
to the use of this Prospectus, together with a Prospectus Supplement, if 
required (as discussed below), for a limited period of time by such 
Affiliates and subject to limitations and conditions which may be varied by 
agreement between the Company and such Affiliates. Resales of such shares may 
be on the limited secondary market (the "Limited Market") maintained by the 
Company through its wholly-owned broker-dealer subsidiary, Bull, Inc., which 
was organized in 1973 for the purpose of providing liquidity to the Company's 
stockholders, or in private transactions. The Limited Market generally 
permits existing stockholders to sell shares of Class A Common Stock on four 
predetermined days each year (each a "Trade Date"). In connection with the 
transactions involving resales of Acquisition Shares, such Affiliates may be 
deemed to be underwriters within the meaning of the Securities Act. Any 
profits realized on such sales by such Affiliates may be regarded as 
underwriting compensation. When resales on behalf of such Affiliates are to 
be 


                                       9

<PAGE>

made through the Limited Market, the Affiliates, like all stockholders 
selling shares in the Limited Market (other than the Company and certain 
employee benefit plans of the Company), will pay the Company's wholly-owned, 
broker-dealer subsidiary, Bull, Inc., a commission equal to two percent of 
the proceeds from their sales. See 1998 10-K, Item 5, "Market for 
Registrant's Common Equity and Related Stockholder Matters -- The Limited 
Market." In connection with such sales, Bull, Inc. may be deemed to be an 
underwriter within the meaning of the Securities Act and any commissions 
earned by Bull, Inc. may be deemed to be underwriting compensation under the 
Securities Act. A Prospectus Supplement, if required, will be filed under 
Rule 424(c) under the Securities Act, disclosing the number of shares 
involved, the price at which such shares were sold by such Affiliate, the 
commissions to be paid by such Affiliate to Bull, Inc. and information about 
the Affiliate.

                      DESCRIPTION OF CLASS A COMMON STOCK

GENERAL

     The Company is authorized to issue 100,000,000 shares of Class A Common 
Stock, par value $.01 per share, 5,000,000 shares of Class B Common Stock, 
par value $.05 per share, and 3,000,000 shares of Preferred Stock, par value 
$.05 per share (the "Preferred Stock"). As of April 13, 1998, there were 
53,287,080 shares of Class A Common Stock, 314,173 shares of Class B Common 
Stock and no shares of Preferred Stock issued and outstanding. The Class A 
Common Stock and the Class B Common Stock are sometimes collectively or 
individually referred to as the "Common Stock." 

COMMON STOCK

GENERAL

     Except as otherwise provided by law, the holders of shares of Class A 
Common Stock and Class B Common Stock vote together as a single class in all 
matters, with each holder of Class A Common Stock having one vote per share 
and each holder of Class B Common Stock having five votes per share. The 
holders of shares of Class A Common Stock and Class B Common Stock are 
entitled to cumulate their votes for the election of directors. Cumulative 
voting entitles each stockholder to cast the number of votes that equals the 
number of shares of Class A Common Stock or five times the number of shares 
of Class B Common Stock held by such stockholder multiplied by the number of 
directors to be elected. Each stockholder may cast all of such votes for a 
single nominee or may distribute them among any two or more nominees as such 
stockholder sees fit. The Certificate of Incorporation provides for a 
classified Board of Directors consisting of three classes of directors, as 
nearly as equal in number as practicable. The number of authorized directors 
is currently fixed at 21 directors, with seven directors serving in each 
class. Each year the stockholders elect a different class of directors to 
serve a three-year term. As a result of the classification of the Board of 
Directors, the votes of a greater number of shares would be required to 
ensure the election of a director than would be required without such 
classification.

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

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


                                      12

<PAGE>

     Pursuant to the terms of the Certificate of Incorporation, the Company 
is prohibited from issuing any additional shares of Class B Common Stock. 
Each share of Class B Common Stock is convertible at any time, at the option 
of the holder thereof, into five shares of Class A Common Stock, and all 
shares of Class B Common Stock reacquired by the Company will be retired and 
will not be available for reissuance.

     Article FOURTEENTH of the Certificate of Incorporation generally 
requires that mergers and certain other business combinations ("Business 
Combinations") between the Company and any holder of 5% or more of the 
Company's outstanding voting power (a "Related Person") must be approved by 
the holders of securities having 80% of the Company's outstanding voting 
power, as well as by the holders of a majority of such securities that are 
not owned by the Related Person. Under Delaware law, unless the Certificate 
of Incorporation provides otherwise, only a majority of the Company's 
outstanding voting power is required to approve certain of these 
transactions, such as mergers and consolidations, while certain other of 
these transactions would not require stockholder approval.

     The 80% and majority of independent voting power requirements of Article 
FOURTEENTH (the "Supermajority Vote Requirements") will not apply, however, 
to a Business Combination with a Related Person, if (i) the transaction is 
approved by the Board of Directors prior to the time the Related Person 
becomes a Related Person (i.e., prior to the time the Related Person acquired 
beneficial ownership of 5% or more of the Company's outstanding voting 
power), (ii) the transaction is approved by at least a majority of the 
members of the Board of Directors who are unaffiliated with the Related 
Person and who were directors before the Related Person became a Related 
Person or (iii) the Business Combination involves only the Company and one or 
more of its subsidiaries and certain other conditions are satisfied.

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

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

     The amendment of certain provisions of the Certificate of Incorporation 
and Bylaws require the approval of not less than two-thirds of the total 
voting power of all outstanding shares of voting stock of the Company. Such 
provisions relate to the number of directors, the election of directors and 
the vote of stockholders required to modify the provisions of the Certificate 
of Incorporation and Bylaws requiring such approvals.

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

     As of April 13, 1998, there were 19,732 record holders of Class A Common 
Stock and 151 record holders of Class B Common Stock.

RESTRICTIONS ON CLASS A COMMON STOCK

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

     RIGHT OF REPURCHASE UPON TERMINATION OF EMPLOYMENT OR AFFILIATION 

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

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

     Notwithstanding the provisions of the Certificate of Incorporation and 
the Company's employee benefit plans, a retiring employee of the Company who 
meets certain criteria can elect to defer the repurchase of the employee's 
shares for five years under the Company's Alumni Program. Under the Alumni 
Program, an employee who is over 59 1/2 and has more than 10 years of 
employment with the Company at the date of his or her retirement can elect to 
have the Company defer its right of repurchase by executing and delivering to 
the Company an agreement within 60 days following the date of the employee's 
termination. If the employee makes such an election, transferees of the 
employee's shares are also eligible to make the same deferral election with 
respect to shares of stock transferred to them by the employee. During the 
five-year deferral period, the stockholder may offer shares of stock for sale 
in the Limited Market or make transfers to family members. At the end of the 
five-year deferral period, all such shares will be subject to repurchase by 
the Company at the then current Formula Price. The Alumni Program pertains 
only to the deferral of the Company's right of repurchase and does not 
provide the employee any rights with respect to the vesting or forfeiture of 
any shares or options


                                      14

<PAGE>

held by the employee at the date of his or her retirement or guarantee the 
repurchase at the end of the deferral period.

     RIGHT OF FIRST REFUSAL

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

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

     TRANSFERS OTHER THAN BY SALE

     Except for sales in the Limited Market and as described above, no holder 
of Class A Common Stock may sell, assign, pledge, transfer or otherwise 
dispose of or encumber any shares of Class A Common Stock without the prior 
written approval of the Company. Any attempt to do so without such prior 
approval will be null and void. The Company may condition its approval of a 
transfer of any shares of Class A Common Stock, other than by sale by an 
employee, director or a consultant of the Company or by a person who acquired 
such shares other than by purchase, directly or indirectly, from an employee, 
director or consultant of the Company, upon the transferee's agreement to 
hold such shares subject to the Company's right to repurchase such shares 
upon the termination of employment or affiliation of the employee, director 
or consultant.

     LAPSE OR WAIVER OF RESTRICTIONS

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

PREFERRED STOCK

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


                                      15

<PAGE>

the Class A Common Stock and Class B Common Stock with respect to dividend, 
redemption and liquidation rights.

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

ANTI-TAKEOVER EFFECTS

     The combined effect of the classification of the Board of Directors into 
three different classes, the cumulative voting rights of the stockholders, 
the Supermajority Vote Requirements, the provisions of the Certificate of 
Incorporation and Bylaws of the Company requiring the approval of at least 
two-thirds of the voting power of all outstanding shares of Common Stock for 
certain amendments to the Certificate of Incorporation or Bylaws, the 
Company's right of first refusal, and the Company's right of repurchase upon 
termination of employment or affiliation, may discourage, delay or prevent 
attempts to acquire control of the Company that are not approved by the 
Company's Board of Directors. The provisions may, individually or 
collectively, have the effect of discouraging takeover attempts that some 
stockholders might deem to be in their best interests, including tender 
offers in which stockholders might receive a premium for their shares over 
the Formula Price available in the Limited Market, as well as making it more 
difficult for individual stockholders or a group of stockholders to elect 
directors. However, the Board of Directors believes that these provisions are 
in the best interests of the Company and its stockholders, because such 
provisions may encourage potential acquirors to negotiate directly with the 
Board of Directors which is in the best position to act on behalf of all 
stockholders. See "Risk Factors--Anti-Takeover Effects."

                                LEGAL MATTERS
                                          
     The legality of the Class A Common Stock offered hereby has been passed 
upon for the Company by Douglas E. Scott, Esquire, Senior Vice President and 
General Counsel of the Company. As of April 13, 1998, Mr. Scott owned of 
record 16,410 shares of Class A Common Stock, had the right to acquire an 
additional 21,000 shares pursuant to previously granted stock options and 
beneficially owned a total of 4,591 shares through the Company's retirement 
plans.

ITEM 22.  UNDERTAKINGS

     (a)  Rule 415 Offering

     The Registrant hereby undertakes:

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

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

                 (ii)    To reflect in the prospectus any facts or events
          arising after the effective date of the Registration Statement (or 
          the most recent post-effective amendment thereof) which, individually
          or in the aggregate, represent a fundamental change in the 
          informationset forth in the Registration Statement; excluding 
          information contained in periodic reports filed with or furnished to 
          the Commission by the Registrant pursuant to Section 13 or 15(d) of 
          the Securities Exchange Act of 1934 that are incorporated by 
          reference in the Registration Statement.

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

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

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

     (b)  Filings Incorporating Subsequent Exchange Act Documents by Reference

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

     (c)  Registration on Form S-4 of Securities Offered for Resale

          (1)    The Registrant hereby undertakes that prior to any public
reoffering of the securities registered hereunder through use of a prospectus
which is a part of this Registration Statement, by any person or party who is
deemed to be an underwriter within the meaning of Rule 145(c), such reoffering
prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other Items of
the applicable form.

          (2)    The Registrant undertakes that every prospectus (i) that is
filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to
meet the requirements of Section 10(a)(3) of the Securities Act 


                                     II-2

<PAGE>

of 1933 and is used in connection with an offering of securities subject to 
Rule 415, will be filed as part of an amendment to the Registration Statement 
and will not be used until such amendment is effective, and that, for 
purposes of determining any liability under the Securities Act of 1933, each 
such post-effective amendment shall be deemed to be a new registration 
statement relating to the securities offered therein, and the offering of 
such securities at that time shall be deemed to be the initial bona fide 
offering thereof.

     (d)  Securities and Exchange Commission Policy Regarding Indemnification

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