                                  COMMON STOCK


                          -----------------------------


     This Prospectus relates to the public offering, which is not being
underwritten, of 238,019 shares (the "Shares") of Common Stock, $0.01 par value
(the "Common Stock"), of Networks Associates, Inc. ("Network Associates" or the
"Company"). The Shares are outstanding shares of Company Common Stock that may
be sold from time to time by or on behalf of certain stockholders of the Company
or by pledges, donees, transferees or other successors in interest that receive
such Shares as a gift, distribution or other non-sale related transfer (the
"Selling Stockholders"). The Selling Stockholders acquired the Shares in private
transactions in which the Company acquired Anyware Seguridad Informatica, S.A.,
a corporation duly organized and existing under the laws of Spain ("Anyware")
and CSB Consulenza Software di Base S.r.l., a corporation duly organized and
existing under the laws of Italy ("CSB").

     The Shares may be offered by the Selling Stockholders from time to time in
transactions on the Nasdaq National Market, in privately negotiated
transactions, or by a combination of such methods of sale, at fixed prices that
may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. The Selling
Stockholders may effect such transactions by selling the Shares to or through
broker-dealers and such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the Selling Stockholders or the
purchasers of the Shares for whom such broker-dealers may act as agent or to
whom they sell as principal or both (which compensation to a particular
broker-dealer might be in excess of customary commissions). See "Selling
Stockholders" and "Plan of Distribution."

     The Company will not receive any of the proceeds from the sale of the
Shares by the Selling Stockholders. The Company has agreed to bear certain
expenses in connection with the registration and sale of the Shares being
offered by the Selling Stockholders. In addition, the Company has agreed to
indemnify the Selling Stockholders against certain liabilities, including
liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"), or the Securities Exchange Act of 1934, as amended (the
"Exchange Act").

                          -----------------------------

     The Selling Stockholders and any broker-dealers or agents that participate
with the Selling Stockholders in the distribution of the Shares may be deemed to
be "underwriters" within the meaning of Section 2(11) of the Securities Act, and
any commissions received by them and any profit on the resale of the Shares
purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act.

RECENT DEVELOPMENTS

     Pending Acquisitions.

     On July 30, 1998, the Company acquired Anyware Seguridad Informatica, S.A.
("Anyware"). The aggregate consideration payable in the acquisition was 228,204
shares of Company Common Stock in a transaction accounted for as a pooling of
interests. Anyware is a developer and distributor of anti-virus software
products based in Madrid, Spain.

     On July 28, 1998, the Company announced that it had entered into a
definitive merger agreement to acquire CyberMedia Inc. ("CyberMedia"), a
publicly traded provider of desktop utility software. Under the terms of the
merger agreement, a subsidiary of the Company will commence a tender offer for
all outstanding shares of CyberMedia for an aggregate purchase price of
approximately $130 million. Following the completion of the tender offer, the
Company's subsidiary will be merged into CyberMedia in a transaction in which
any CyberMedia shares not tendered will be converted into the right to receive
the same per share cash price in the tender offer. Completion of the tender
offer is subject to customary conditions, including the tender of a majority of
the CyberMedia shares, receipt of necessary governmental approvals and the
expiration of applicable waiting periods under the Hart-Scott-Rodino Act.

     On June 29, 1998, the Company acquired CSB Consulenza Software di Base
S.r.l. ("CSB"). The aggregate consideration payable in the acquisition was 9,815
shares of Company Common Stock in a transaction accounted for as a pooling of
interests. CSB is a reseller of software applications and services based in
Milan, Italy.

     On June 9, 1998, the Company and Dr Solomon's Group Plc, a corporation duly
organized and existing under the laws of England and Wales ("Dr Solomon"),
agreed to the terms of the proposed acquisition of all the issued share capital
of Dr Solomon by Network Associates by means of a Scheme of Arrangement in
accordance with Section 425 of the Companies Act (as amended) of England and
Wales. Dr Solomon is a publicly traded company and a leading European-based
provider of anti-virus software products. Pursuant to the terms of the
transaction agreement, dated June 9, 1998, by and between Dr Solomon and the
Company, holders of Dr Solomon Ordinary Shares will receive 0.27625 shares of
Network Associates Common Stock for each Dr Solomon Ordinary Share. As one Dr
Solomon's American Depository Share ("ADS") represents three Dr Solomon Ordinary
Shares, this is equivalent to 0.82875 shares of Network Associates Common Stock
for each Dr Solomon ADS. Network Associates and Dr Solomon currently expect to
consummate the Dr Solomon acquisition on August 13, 1998, although there can be
no assurance to that effect. The Dr Solomon acquisition remains subject to
fulfillment of certain conditions, including clearance and the sanction of the
English High Court. The Dr Solomon acquisition will be accounted for as a
pooling of interests.

     Recent Acquisitions.

     On May 15, 1998, the Company acquired Secure Networks, Inc. ("Secure"). The
aggregate consideration payable in the acquisition was 567,000 shares of Company
Common Stock in a transaction accounted for as a pooling of interests. Secure is
a developer and licensor of network security auditing software based in Canada.

     On April 28, 1998, the Company acquired Trusted Information Systems, Inc.
("TIS"), a publicly held provider of comprehensive security solutions for the
protection of computer networks, including global Internet-based systems,
internal networks and individual workstations and laptops, as well as firewall
and intrusion detection products. In the acquisition, a wholly owned subsidiary
of the Company merged with and into TIS; TIS became a wholly owned subsidiary of
the Company; each outstanding share of TIS Common Stock converted into the right



                                        6

<PAGE>   9


to receive 0.4845 of a share of Company Common Stock. The TIS acquisition
broadened the Company's suite of network security products. The TIS acquisition
was qualified as a pooling of interests for financial reporting purposes in
accordance with generally accepted accounting principles.

     On April 1, 1998, the Company acquired Magic Solutions International, Inc.
("Magic Solutions"), a privately held provider of internal help desk and asset
management solutions. In the acquisition, a wholly owned subsidiary of the
Company merged with and into Magic Solutions; Magic Solutions became a wholly
owned subsidiary of the Company; and the existing Magic Solutions stock and
option holders received approximately $110,000,000 in cash. The Magic Solutions
acquisition broadened the Company's suite of help desk product offerings. The
Magic Solutions acquisition is accounted for as a purchase.

     On March 30, 1998, the Company acquired (subject to a right of repurchase)
a percentage interest in Nordic Lantools AB ("Nordic AB"). The aggregate
consideration payable in the acquisition was 4,594 shares of Company Common
Stock. Nordic AB is a distributor of software products based in Sweden.

     On February 27, 1998, the Company acquired 100% of the issued share capital
of Nordic Lantools Oy ("Nordic Oy"). The aggregate consideration payable in the
acquisition was 41,167 shares of Company Common Stock in a transaction accounted
for as a pooling of interests. Nordic Oy is a distributor of software products
based in Finland.

     On February 26, 1998, the Company acquired 100% of the issued share capital
of Syscon (Proprietary) Limited ("Syscon"). The aggregate consideration payable
in the acquisition was 1,845 shares of Company Common Stock in a transaction
accounted for as a pooling of interests. Syscon is a distributor of software
products and is based in South Africa.

     Each of the pending acquisitions and the other recent acquisitions
(particularly the Magic Solutions and TIS acquisitions) is subject to a number
of risks, including the difficulties of assimilating the company's sales forces,
product offerings, marketing activities, research and development efforts and
technologies. These difficulties may be compounded in light of the integration
activities surrounding multiple acquisitions.

     Common Stock Split. On May 29, 1998 the Company effected a 3-for-2 stock
split by means of a 50% stock dividend pursuant to which stockholders of record
on May 12, 1998 received one share of Company Common Stock for every two shares
of Company Common Stock held by them (with cash paid in lieu of fractional
shares).

                                  RISK FACTORS

     This Prospectus, including the documents incorporated by reference herein,
contains forward-looking statements that involve risks and uncertainties. The
statements contained in this Prospectus or incorporated by reference herein that
are not purely historical are forward-looking statements within the meaning of
Section 27A of the Securities Act and Section 21E of the Exchange Act, including
without limitation statements regarding the Company's expectations, beliefs,
intentions or strategies regarding the future. All forward-looking statements
included in this document or incorporated by reference herein are based on
information available to the Company on the date hereof, and the Company assumes
no obligation to update any such forward-looking statements. The



                                        7

<PAGE>   10



Company's actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth in "Risk Factors" and elsewhere in this Prospectus.

     Variability of Quarterly Operating Results. The Company's results of
operations have been subject to significant fluctuations, particularly on a
quarterly basis, and the Company's future results of operations could fluctuate
significantly from quarter to quarter and from year to year. Causes of such
fluctuations may include the volume and timing of new orders and renewals,
distributor inventory levels and return rates, Company inventory levels, the
introduction of new products, product upgrades or updates by the Company or its
competitors, changes in product mix, changes in product prices and pricing
models, seasonality, trends in the computer industry, general economic
conditions (such as the recent economic turbulence in Asia), extraordinary
events such as acquisitions or litigation and the occurrence of unexpected
events. The operating results of many software companies reflect seasonal
trends, and the Company's business, financial condition and results of
operations may be affected by such trends in the future. Such trends may include
higher net revenue in the fourth quarter as many customers complete annual
budgetary cycles, and lower net revenue in the summer months when many
businesses experience lower sales, particularly in the European market.

     Although the Company has experienced significant growth in net revenue and
net income (before acquisition and other related costs) in absolute terms, the
Company's growth rate has slowed in recent periods. The Company has experienced
increased price competition for its products and the Company expects competition
to increase in the near-term, which may result in reduced average selling prices
for the Company's products. Due to these and other factors (such as a maturing
anti-virus market and an increasingly higher base from which to grow), the
Company's historic revenue growth rate is difficult to sustain or increase. To
the extent these trends continue, the Company's results of operations could be
materially adversely affected. Renewals have historically accounted for a
significant portion of the Company's net revenue; however, there can be no
assurance that the Company will be able to sustain historic renewal rates for
its products in the future. Risks related to the Company's recent change in
business strategies could also cause fluctuations in operating results and could
make comparisons with historic operating results and balances difficult or not
meaningful. See "-- Risks Related to Certain Business Strategies."

     The timing and amount of the Company's revenues are subject to a number of
factors that make estimating operating results prior to the end of a quarter
uncertain. The Company does not expect to maintain a significant level of
backlog and, as a result, product revenues in any quarter are dependent on
contracts entered into or orders booked and shipped in that quarter. During
1997, the Company generally experienced a trend toward higher order receipts
toward the end of the last month of a quarter, resulting in a higher percentage
of revenue shipments during the last month of a quarter than in 1996, which
makes predicting revenues more difficult. The timing of closing larger orders
increases the risks of quarter-to-quarter fluctuation. To the extent that the
Company is successful in licensing larger product suites under the Net Tools
umbrella (particularly to large enterprise and national accounts), the size of
its orders and the length of its sales cycle are likely to increase. If orders
forecasted for a specific customer for a particular quarter are not realized or
revenues are not otherwise recognized in that quarter, the Company's operating
results for that quarter could be materially adversely affected. See " --
Potentially Longer Sales and Implementation Cycles for Certain Products."

     The trading price of the Company's Common Stock has historically been
subject to wide fluctuations, with factors such as earnings announcements and
litigation developments contributing to this volatility. Failure to achieve
periodic revenue, earnings and other operating and financial results as
forecasted or anticipated by brokerage firms, industry analysts or investors
could result in an immediate and adverse effect on the market price of the
Company's Common Stock. The Company may not discover, or be able to confirm,
revenue or earnings shortfalls until the end of a quarter, which could result in
an immediate and adverse effect on the price of the Company's Common Stock.

     Risk of Inclusion of Network Management and Security Functionality in
Hardware and Other Software. In the future, vendors of hardware and of operating
system software or other software (such as firewall or electronic mail software)
may continue to enhance their products or bundle separate products to include
functionality that currently is provided primarily by network security and
management software. Such enhancements may be achieved through the addition of
functionality to operating system software or other software or the bundling of
network security and management software with operating system software or other
products. For example, Cisco Systems, Inc. ("Cisco") recently incorporated a
firewall in certain of its hardware products and Microsoft Corporation
("Microsoft") introduced limited anti-virus functionality into its MS-DOS
versions in 1993. The widespread inclusion of the functionality of the Company's
products as standard features of computer hardware or of operating system
software or other software could render the Company's products obsolete and
unmarketable, particularly if the quality of such functionality were comparable
to that of the Company's products. Furthermore, even if the network security
and/or management functionality provided as standard features by hardware
providers or operating systems or other software is more limited than that of
the Company's products, there can be no assurance that a significant number of
customers would not elect to accept such functionality in lieu of purchasing
additional software. If the Company were unable to develop new network security
and management products to further enhance operating systems or other software
and to replace successfully any obsolete products, the Company's business,
financial condition and results of operations would be materially adversely
affected.

     Risks Associated with Pending and Recent Acquisitions. In addition to risks
described under "-- Risks Associated with Acquisitions Generally," the Company
faces significant risks associated with its recent combination with Network
General and other pending and recent acquisitions (including the acquisitions of
PGP, Helix, Magic Solutions and TIS). There can be no assurance that the Company
will realize the desired benefits of these transactions. In order to
successfully integrate these companies, the Company must, among other things,
continue to attract and retain key management and other personnel; integrate,
both from an engineering and a sales and marketing perspective, the acquired
products (including Network General's Sniffer and CyberCop products, PGP's
encryption products, Helix's utilities products, Magic Solution's help desk
products and TIS's firewall products) into its suite of product offerings;
integrate and develop a cohesive focused direct and indirect sales force for its
product offerings; consolidate duplicate facilities; and develop name
recognition for its new name. The diversion of the attention of management from
the day-to-day operations of the Company, or difficulties encountered in the
integration process, could have a material adverse effect on the Company's
business, financial condition and results of operations. See "-- Need to Develop
Enterprise and National Accounts Sales Force and Security Products Sales Force;
Risks Related to Direct Sales Force" and "-- Use of Indirect Sales Channels;
Need to Develop Indirect Sales Channel for Sniffer and PGP Security Products."

     During 1997 and the quarter ended June 30, 1998, the Company incurred
significant non-recurring charges associated with the Network General
combination and the acquisitions of PGP, Helix, Magic Solutions and TIS. During
the third quarter of 1998, the Company expects to incur additional non-recurring
charges associated with the pending acquisition of Dr Solomon and CyberMedia.
There can be no assurance that the Company will not incur additional material
charges in subsequent quarters to reflect additional costs associated with these
transactions and with respect to its name change and the marketing of its
products under the "Network Associates" name.

     Risks Related to Certain Business Strategies. The Company has historically
derived a significant majority of its revenues from the licensing of its
flagship anti-virus products and Sniffer products. See "-- Dependence on Revenue
from Flagship Anti-Virus and Sniffer Products." The Company is currently
focusing its efforts on broadening its revenue base by providing network
security and management solutions to enterprise customers, targeting in
particular the Windows NT/Intel platform. In furtherance of this strategy, the
Company recently organized its products into four product suites -- McAfee Total
Virus Defense, PGP Total Network Security, and Sniffer Total Network Visibility
and McAfee Total Virus Defense. These four product suites together form an



                                        9

<PAGE>   12



integrated solution called "Net Tools" which utilizes a new pricing model. There
can be no assurance that potential customers will respond favorably to the
modified pricing structure and the lack of a favorable response could materially
adversely affect the Company's operating results. Although the Company will
continue to offer perpetual licenses with annual support and maintenance
contracts for its Sniffer products, it is currently developing a subscription
licensing model for those products. In addition, in an effort to increase total
Sniffer unit sales the Company intends to develop software only versions of
certain of its Sniffer products -- meaning that the Company would no longer sell
the hardware components contained in these Sniffer products. There can be no
assurance that the Company can produce a software only Sniffer product on a
timely basis or at all, that customers will not continue to require that the
Company provide the associated hardware platform and components, that total unit
licenses of Sniffer products will increase over previous levels or that
customers will react favorably to the subscription pricing model for Sniffer
products. To the extent that customers do license Sniffer products on a two-year
subscription basis or license significant amounts of software only Sniffer
products, the Company's operating results and financial condition would likely
be affected. In the case of subscription licenses, the Company would, among
other things, expect an increase in deferred revenues related to the service
portion of the two-year Sniffer license that would be capitalized on the
Company's balance sheet. In the initial year of the license, the corresponding
revenue would be lower than if the license were perpetual. In the case of the
software only Sniffer product, for any individual license, the Company would
expect lower total revenues and a higher overall gross margin related to the
transaction, as the Company would not be selling the corresponding hardware
component. Currently, the hardware component has a lower gross margin than the
total product gross margin.

     The Company has been acquiring (and is continuing to investigate the
acquisition of) existing independent agents and distributors of its products in
certain strategic markets or has been converting these independent agents into
resellers who must purchase Company products from Company approved distributors.
These actions may require, among other things, that the Company provide the
technical support to customers that was previously provided by such agents and
distributors. There can be no assurance that the Company can provide such
support as effectively or on a timely basis or at all, that the Company will
operate any acquired distributor or agent as successfully as the previous
operators, that the acquisition of any distributor or agent or the conversion of
any agent into a reseller will result in the desired increased foreign revenues
or that the Company is able to identify and retain suitable distributors in any
market in which it converts an independent agent. See " -- Risks Associated with
Acquisitions Generally" and " -- Risks Related to International Revenue and
Activities."

     As part of the Net Tools concept, the Company is in the process of
designing a centralized console from which the various component suites can be
operated, administered and maintained utilizing a common look and feel. The
Company faces significant engineering challenges related to these efforts. In
addition, the Company faces significant engineering and other challenges related
to the integration of its various security products (such as its recently
acquired PGP/TIS encryption products and Network General CyberCop product) into
a marketable suite of products and the development of a software only Sniffer
product. Success of the Company's Net Tools suite strategy will also depend, in
part, upon successful development and coordination of the Company's sales force;
on successful development of a national accounts sales force and an effective
indirect sales channel for the Company's Sniffer and PGP/TIS security products;
and on the development and expansion of an effective professional services
organization. See " -- Risks Associated with Recent Transactions," " -- Risks
Associated with Acquisitions Generally," " -- Need to Develop Enterprise and
National Accounts Sales Force and Security Products Sales Force; Risks Related
to Direct Sales Force," " -- Use of Indirect Sales Channels; Need to Develop
Indirect Sales Channel for Sniffer and PGP Security Products" and " -- Need to
Expand and Develop An Effective Professional Services Organization."

     The foregoing factors, individually or in the aggregate, could materially
adversely affect the Company's operating results and could make comparison of
historic operating results and balances difficult or not meaningful.



                                       10

     Risks Associated with Acquisitions Generally. The software industry has
experienced and is expected to continue to experience a significant amount of
consolidation. In addition, it is expected that the Company will grow internally
and through strategic acquisitions in order, among other things, to expand the
breadth and depth of its product suites and to build its professional services
organization. The Company continually evaluates potential acquisitions of
complementary businesses, products and technologies. In addition to the
combination with Network General in December 1997, the Company has consummated a
series of significant acquisitions since 1994, including the acquisitions of
Magic Solutions and TIS in April 1998, the acquisitions of PGP and Helix in
December 1997, Cinco Networks, Inc. in August 1997, 3DV Technology, Inc. in
March 1997, FSA Corporation of Canada in August 1996, Vycor Corporation in
February 1996, Saber Software Corporation, Inc. in August 1995 and ProTools,
Inc. in January 1994. In addition, since 1995 the Company has acquired a number
of its international distributors, including distributors in Australia, Brazil,
Japan, Sweden, South Africa and The Netherlands and is currently investigating
acquisitions of additional foreign distributors. Past acquisitions have
consisted of, and future acquisitions will likely include, acquisitions of
businesses, interests in businesses and assets of businesses. Any acquisition,
depending on its size, could result in the use of a significant portion of the
Company's available cash or, if such acquisition is made utilizing the Company's
securities, could result in significant dilution to the Company's stockholders,
and could result in the incurrence of significant acquisition related charges to
earnings. Acquisitions by the Company may result in the incurrence or the
assumption of liabilities, including liabilities that are unknown or not fully
known at the time of acquisition, which could have a material adverse effect on
the Company. Furthermore, there can be no assurance that any products acquired
in connection with any such acquisition will gain acceptance in the Company's
markets or that the Company will obtain the anticipated or desired benefits of
such transactions.

     Achieving the anticipated benefits of an acquisition will depend, in part,
upon whether the integration of the acquired business, products or technology is
accomplished in an efficient and effective manner, and there can be no assurance
that this will occur. Moreover, successful acquisitions in the high technology
industry may be more difficult to accomplish than in other industries. Combining
a merged or acquired company requires, among other things, integration of
product offerings and coordination of sales and marketing and research and
development efforts. There can be no assurance that such an integration can be
accomplished smoothly or successfully. The difficulties of such integration may
be increased by the necessity of coordinating geographically separated
organizations, the complexity of the technologies being integrated, and the
necessity of integrating personnel with disparate business backgrounds and
combining two different corporate cultures. The integration of operations
following an acquisition requires the dedication of management resources that
may distract attention from the day-to-day business, and may disrupt key
research and development, marketing or sales efforts. The inability of
management to successfully integrate any acquisition could have a material
adverse effect on the business, operating results and financial condition of the
Company. In addition, as commonly occurs, during the pre-acquisition and
integration phases of technology company acquisitions, aggressive competitors
may undertake initiatives to attract customers and to recruit key employees
through various incentives.

     Rapid Technological Change; Risks Associated with Product Development. The
network security and management market is highly fragmented and is characterized
by ongoing technological developments, evolving industry standards and rapid
changes in customer requirements. The Company's success depends upon its ability
to offer a broad range of network security and management software products, to
continue to enhance existing products, to develop and introduce in a timely
manner new products that take advantage of technological advances, and to
respond promptly to new customer requirements. While the Company believes that
it offers one of the broadest product lines in the network management and
security market, this market is continuing to evolve and customer requirements
are continuing to change. As the market evolves and competitive pressures
increase, the Company believes that it will need to further expand its product
offerings. There can be no assurance that the Company will be successful in
developing and marketing, on a timely basis, enhancements to its existing
products



                                       11

<PAGE>   14



or new products, or that such enhancements or new products will adequately
address the changing needs of the marketplace.

     In addition, from time to time, the Company or its competitors may announce
new products with new or additional capabilities or technologies. Such
announcements of new products could have the potential to replace, or shorten
the life cycles of, the Company's existing products and to cause customers to
defer or cancel purchases of the Company's existing products.

     The Company has in the past experienced delays in software development, and
there can be no assurance that the Company will not experience delays in
connection with its current or future product development activities. Complex
software products such as those offered by the Company may contain undetected
errors or version compatibility issues, particularly when first introduced or
when new versions are released, resulting in loss of or delay in market
acceptance. For example, the Company experienced compatibility issues in
connection with its recent NetShield upgrade, and the Company's anti-virus
software products have in the past falsely detected viruses that did not
actually exist. See " -- Risk of False Detection of Viruses." Delays and
difficulties associated with new product introductions, performance or
enhancements could have a material adverse effect on the Company's business,
financial condition and results of operation.

     The Company's development efforts are impacted by the adoption or evolution
of industry standards related to its products and the environments in which they
operate. For example, no uniform industry standard has developed in the market
for encryption security products. As industry standards are adopted or evolve,
the Company may be required to modify existing products or develop and support
new versions of existing products. In addition, to the extent that no industry
standard develops, the Company's products and those of its competitors may be
incompatible if they use competing standards, which could prevent or
significantly delay overall development of the market for a particular product
or products. The failure of the Company's products to comply, or delays in
compliance, with existing or evolving industry standards could have a material
adverse effect on the Company's business, financial condition and results of
operation.

     The Company's long-term success will depend on its ability on a timely and
cost-effective basis to develop upgrades and updates to its existing product
offerings, to modify and enhance acquired products, and to introduce new
products which meet the needs of current and potential customers. Future
upgrades and updates may, among other things, include additional functionality,
respond to user problems or address issues of compatibility with changing
operating systems and environments. The Company believes that the ability to
provide these upgrades and updates to users frequently and at a low cost is a
key to success. For example, the proliferation of new and changing viruses makes
it imperative to update anti-virus products frequently in order for the products
to avoid obsolescence. Failure to release such upgrades and updates on a timely
basis could have a material adverse effect on the Company's business, financial
condition and results of operations. There can be no assurance that the Company
will be successful in these efforts. In addition, future changes in Windows 95,
Windows NT, NetWare or other popular operating systems may result in
compatibility problems with the Company's products. Further, delays in the
introduction of future versions of operating systems or lack of market
acceptance of future versions of operating systems would result in a delay or a
reduction in the demand for the Company's future products and product versions
which are designed to operate with such future versions of operating systems.
The Company's failure to introduce in a timely manner new products that are
compatible with operating systems and environments preferred by desktop computer
users would have a material adverse effect on the Company's business, financial
condition and results of operations.

     Dependence on Revenue from Flagship Anti-Virus and Sniffer Products. In
recent years, the Company has derived a substantial majority of its net revenue
from its flagship McAfee anti-virus software products and Sniffer



                                       12

<PAGE>   15



network fault and performance management products. These products are expected
to continue to account for a significant portion of the Company's net revenue
for the foreseeable future. Because of this concentration of revenue, a decline
in demand for, or in the prices of, these anti-virus and network management
products as a result of competition, technological change, a change in the
Company's pricing model for such products, the inclusion of anti-virus or
network management and analysis functionality in system hardware or operating
system software or other software or otherwise, or a maturation in the
respective markets for these products could have a material adverse effect on
the Company's business, financial condition and results of operations.

     Dependence on Emergence of Network Management and Network Security Markets.
The markets for the Company's network management and network security products
are evolving, and their growth depends upon broader market acceptance of network
management and network security software, including help desk software. Although
the number of LAN-attached personal computers ("PCs") has increased
dramatically, the network management and network security markets continue to be
emerging markets and there can be no assurance that such markets will continue
to develop or that further market development will be rapid enough to benefit
the Company significantly. In addition, there are a number of potential
approaches to network management and network security, including the
incorporation of management and security tools into network operating systems.
Therefore, even if network management and network security tools gain broader
market acceptance, there can be no assurance that the Company's products will be
chosen by organizations which acquire network management and network security
tools. Furthermore, to the extent that either the network management or network
security market does continue to develop, the Company expects that competition
will increase. See "-- Competition" and "-- Risk of Inclusion of Network
Security and Management Functionality in Hardware and Other Software."

     Competition. The markets for the Company's products are intensely
competitive, and the Company expects competition to increase in the near-term.
The Company believes that the principal competitive factors affecting the
markets for its products include performance, functionality, quality, customer
support, breadth of product line, frequency of upgrades and updates, integration
of products, manageability of products, brand name recognition, company
reputation and price. Certain of the criteria upon which the performance and
quality of the Company's anti-virus software products compete include the number
and types of viruses detected, the speed at which the products run and ease of
use. Certain of the Company's competitors have been in the network management
market longer than the Company, and other competitors, such as Symantec
Corporation ("Symantec"), Intel Corporation ("Intel"), Seagate Technology Inc.
("Seagate") and Hewlett-Packard Company ("HP"), are larger and have greater name
recognition than the Company. The Company will also need to develop name
recognition for its new name, "Network Associates." In addition, certain larger
competitors such as Intel, Microsoft and Novell Inc. ("Novell") have established
relationships with hardware vendors related to their other product lines. These
relationships may provide them with a competitive advantage in penetrating the
OEM market with their network security and management products. As is the case
in many segments of the software industry, the Company has been encountering,
and expects to further encounter, increasing competition. This increased
competition could reduce average selling prices and, therefore, profit margins.
Competitive pressures could result not only in sustained price reductions but
also in a decline in sales volume, which events would materially adversely
affect the Company's business, financial condition and results of operations. In
addition, competitive pressures may make it difficult for the Company to
maintain or exceed its growth rate.

     Although there is a trend toward consolidation in the network security and
management market, the market is currently highly fragmented with products
offered by many vendors. The Company's principal competitor is the Peter Norton
Group of Symantec in the network security market and Intel's LanDesk in the
network management market. The Company's other competitors include Computer
Associates/Cheyenne Software, IBM, Seagate, the Dr Solomon Group and Trend
Micro, Inc., as well as numerous smaller companies and shareware authors that
may in the future develop into stronger competitors or be consolidated into
larger competitors. In the encryption portion



                                       13

<PAGE>   16



of the security market, the Company's principal competitors are Security
Dynamics Technologies, Inc., Cylink Corporation, Entrust Technologies and
VeriSign, Inc. The Company's principal competitors in the help desk market are
Remedy Corporation and Software Artistry (recently acquired by Tivoli
Systems/IBM) and Magic Solutions, Inc. The Company's principal competitor in the
software-based network fault and performance management market is HP, with other
competitors including Azure Technologies Incorporated, Concord Communications,
DeskTalk Systems, Kaspia Systems, Shomiti Systems, Inc. and Wandel & Goltermann,
Inc. The Company also faces competition in the security market from Cisco,
Security Dynamics Technologies, Inc., Checkpoint Software and other vendors in
the encryption/firewall market. In addition, the Company faces competition from
large and established software companies such as Microsoft, Intel, Novell and HP
which offer network management products as enhancements to their network
operating systems. As the network management market develops, the Company may
face increased competition from these large companies, as well as other
companies seeking to enter the market. The trend toward enterprise-wide network
management and security solutions may result in a consolidation of the network
management and security market around a smaller number of vendors who are able
to provide the necessary software and support capabilities. In addition, to the
extent that the Company is successful in developing its Net Tools suite of
products designed around a centralized management and administration console for
the Windows NT platform, the Company will likely compete with large computer
systems management companies such as Tivoli Systems (TME) and Computer
Associates (Unicenter). There can be no assurance that the Company will continue
to compete effectively against existing and potential competitors, many of whom
have substantially greater financial, technical, marketing and support resources
and name recognition than the Company. In addition, there can be no assurance
that software vendors who currently use traditional distribution methods will
not in the future decide to compete more directly with the Company by utilizing
electronic software distribution.

     The competitive environment for anti-virus software internationally is
similar to that in North America, although local competitors in specific foreign
markets present stronger competition and shareware authors control a more
significant portion of the European market. The international market for network
management software has developed more slowly than the North American market,
although larger competitors such as Intel and Symantec have begun to penetrate
European markets. Asian markets have lagged significantly behind North America
and Europe in their adoption of networking technology. There can be no assurance
that the Company will be able to compete successfully in international markets.

     Need to Develop Enterprise and National Accounts Sales Force and Security
Products Sales Force; Risks Related to Direct Sales Force. In connection with
its recent acquisitions and as part of its evolving strategy of offering product
suites under the Net Tools umbrella, the Company has recently reorganized its
direct sales force into three tiers. The first tier focuses on the sale of the
full product suite under the Net Tools umbrella to enterprise and national
account customers. The second tier consists of four separate sales groups
focused on the sale of the individual product suites (i.e., McAfee Total Virus
Defense; PGP Total Network Security; Sniffer Total Network Visibility; or McAfee
Total Service Desk) to the departmental level. The third tier consists of four
separate outbound corporate telesales forces who actively market the Company's
individual product suites to customers with less than 1,000 nodes. The Company
historically has not had a large enterprise or national accounts sales force and
only recently developed a direct sales group focused on these larger accounts.
In addition, the Company has not historically had a separate sales force focused
on the sale of its suite of security products (many of which were only recently
acquired and are currently being engineered into a common suite). To succeed in
the direct sales channel for the enterprise and national accounts market and for
the sale of the separate security product suite, the Company will be required to
build a significant direct sales organization and will be required to attract
and retain qualified personnel, which personnel will require training about, and
knowledge of, product attributes for the Company's suite of products. There can
be no assurance that the Company will be successful in building the necessary
sales organization or in attracting, retaining or training these individuals.
Historically, the Company has sold its products at the departmental level. To
succeed in the enterprise and national accounts market will require, among other



                                       14

<PAGE>   17



things, establishing relationships and contacts with senior technology officers
at these accounts. There can be no assurance that the Company or its sales force
will be successful in these efforts.

     The Company's sales organization structure may result in multiple customer
contacts by different Company sales representatives (particularly in
circumstances where the customer has multiple facilities and offices), a lack of
coordination between the Company's various sales organizations and a lack of
focus by the individual sales representatives on their designated customers or
products. The occurrence of these events could lead to customer confusion,
disputes in the sales force and lost revenue opportunities which could have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, while the development of a direct sales
channel reduces the Company's dependence on resellers and distributors, it may
lead to conflicts for the same customers and further customer confusion,
pressure by current and prospective customers for price reductions on products
and, consequently, in reductions in the Company's gross margin and operating
profit.

     Use of Indirect Sales Channels; Need to Develop Indirect Sales Channel for
Sniffer and PGP Security Products. The Company markets a significant portion of
its products to end-users through distributors, resellers and VARs. The
Company's distributors sell other products that are complementary to, or compete
with, those of the Company. While the Company encourages its distributors to
focus on its products through market and support programs, there can be no
assurance that these distributors will not give greater priority to products of
other suppliers, including competitors.

     The Company does not have an extensive indirect sales channel for its
Network Sniffer products or its PGP security products. To succeed in the
indirect sales channel, the Company will be required to build a more extensive
network of distributors, resellers and VARs who will support and market these
products. These indirect channel participants will require significant training
about, and knowledge of, product attributes for these products and the related
product suites. There can be no assurance that the Company can successfully
establish such an indirect channel on a timely basis or at all or that such a
channel, once established, can be maintained.

     The Company's agreements with its distributors provide for a right of
return. This right of return may be triggered by a number of events, including
returns to distributors by end users, inaccurate estimates of end user demand by
distributors, increased purchases by distributors in response to sales
incentives or transitions to new products or versions of products. As a result
of this right of return, revenue recognized by the Company upon sales to
distributors is subject to a reserve for returns. Returns could exceed reserves
as a result of distributors holding excessive Company product inventory. There
can be no assurance that current or future reserves established by the Company
will be adequate.

     Need to Expand and Develop An Effective Professional Services Organization;
Risks Related to Third-Party Professional Services. As the Company's products
and computer networks become more complex, customers will increasingly require
greater professional assistance in the design, installation, configuration and
implementation of their networks and acquired products. To date, the Company has
relied on its limited professional services capabilities and increasingly on
outside professional service providers (including its distributors, resellers
and system integrators). There can be no assurance that third party service
providers can or will continue to be willing to provide adequate levels (both in
terms of time and quality) of professional services. Moreover, reliance on these
third parties reduces the Company's control over the provision of support
services for its products and places a greater burden on these third parties,
which, in turn, could delay the Company's recognition of product revenue, could
harm the Company's relationships or reputation with such third parties or the
end users of its products and could result in decreased future sales of, or
prices for, its products.


                                       15

     To more effectively service its customer's evolving needs, the Company
intends to significantly expand and develop its worldwide professional service
organization. There can be no assurance that the Company will be successful in
its efforts to expand and develop an effective professional services
organization. This will require that the Company hire and train additional
service professional who must be continually trained and educated to ensure that
they possess sufficient technical skills and product knowledge. In particular,
the market for qualified professionals is intensely competitive, making hiring
and retention difficult. The Company expects significant competition in this
market from existing providers of professional services and future entrants. The
Company must also properly price its services to attract customers, while
maintaining sufficient margins for its services. The Company expects that it
will have lower profit margins on its service revenues. The failure to develop
an effective professional services organization could have a material adverse
effect on the Company's business, financial condition and results of operations.

     Reliance on Microsoft Technology. Although the Company intends to support
other operating systems, the Company's mission is to be the leading supplier of
network security and management products for Windows NT/Intel based networks.
Sales of the Company's products would be materially and adversely affected by
market developments which are adverse to the Windows operating environments,
including the failure of users and application developers to accept Windows NT.
In addition, the Company's ability to develop products using the Windows
operating environments is substantially dependent on its ability to gain timely
access to, and to develop expertise in, current and future developments by
Microsoft, of which there can be no assurance.

     Risks Associated with Failure to Manage Growth. The Company's growth
internally and through its numerous acquisitions has placed, and any further
expansion would continue to place, a significant strain on its limited
personnel, management and other resources. In the future, the Company's ability
to manage any growth, particularly with the anticipated expansion of the
Company's international business and growth in indirect channel business, will
require it to attract, train, motivate and manage new employees successfully, to
effectively integrate new employees into its operations and to continue to
improve its operational, financial, management and information systems and
controls. The failure to effectively manage any further growth could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     Proprietary Technology and Rights; Litigation. The Company's success is
heavily dependent upon proprietary software technology. The Company relies on a
combination of contractual rights, trademarks, trade secrets and copyrights to
establish and protect proprietary rights in its software. There can be no
assurance these protections will be adequate or that competitors will not
independently develop technologies or products that are substantially equivalent
or superior to the Company's products.

     Network Associates has changed its legal name to "Networks Associates,
Inc." and has begun conducting business as "Network Associates." Two companies,
(Network Associates, Inc. in Kansas ("NAI-Kansas"); and Network Associates, Inc.
in Oregon ("NAI-Oregon")) and Ronald L. Meyers ("Myers"), a California resident
doing business as The Network Associates, have made unresolved claims (including
various trademark claims) or demands with respect to Network Associates' use of
the name Network Associates. On March 26, 1998, Network Associates commenced a
declaratory judgement action in the United States District Court, Northern
District of California against all three of the above-cited claimants. Network
Associates seeks a declaration that its use of the NETWORK ASSOCIATES title does
not violate the federal, state or common law rights of any of the defendants.
Defendants NAI-Oregon and NAI-Kansas have since been granted extensions of time
in which to respond to the Complaint; defendant Myers has not yet been served.
NAI Kansas has moved to dismiss the claims against it for lack of personal
jurisdiction.

     On April 24, 1997, Network Associates was served by Symantec with a suit
filed in the United States District Court, Northern District of California, San
Jose Division, alleging copyright infringement and unfair competition by Network
Associates. Symantec alleges that Network Associates' computer software program
called "PC Medic" copied portions of Symantec's computer software program
entitled "CrashGuard." Symantec's complaint sought injunctive relief and
unspecified money damages. On July 20, 1997, Symantec sought leave to amend its
complaint to include additional allegations of copyright infringement and trade
secret misappropriation pertaining to Network Associates' "VirusScan" product.
Symantec sought injunctive relief and unspecified money damages. On October 6,
1997, the Court issued an order granting Symantec's motion to amend its
complaint and enjoining Network Associates from shipping any product containing
either an approximately 30-line routine found in Crash Guard or an approximately
100-line routine found in a Symantec DLL. The Court's order expressly stated
that "the court is not enjoining the sale or distribution of [McAfee's] current
product." On December 19, 1997, the Court denied Symantec's motion to enjoin
sale or distribution of Network Associates' current PC Medic product. On April
1, 1998, Symantec filed an amended complaint including additional allegations of
trade secret misappropriation, unfair competition, interference with economic
advantage and contractual relations and violations of the Racketeer Influenced
and Corrupt Organization Act ("RICO"), in connection with the alleged use by
Network Associates employees of proprietary Symantec customer information. On
April 10, 1998, Network Associates moved to dismiss the RICO claims. Symantec
also filed a motion for a preliminary injunction relating to these new
allegations which is scheduled for hearing on June 5, 1998. Trial is currently
set for September 1998. On August 10, 1998, the Court will hear a motion by
Symantec to vacate the trial date provided to it by Network during 1997.
Network is opposing the motion.

     On June 9, 1998, the Court dismissed Symantec's unfair competition claim
regarding allegations concerning source code with prejudice and dismissed
Symantec's racketeering claim without prejudice. On June 15, 1998, the Court
entered a stipulated preliminary injunction prohibiting Network Associates from
making use of any Symantec customer list data.

     On May 13, 1997, Trend Micro, Inc. ("Trend") filed suit in United States
District Court for the Northern District of California against both Network
Associates and Symantec. Trend alleges that Network Associates' "WebShield" and
"GroupShield" products infringe a Trend patent which issued on April 22, 1997.
Trend's complaint seeks injunctive relief and unspecified money damages. On June
6, 1997, Network Associates filed its answer denying any infringement. Network
Associates also filed counterclaims against Trend alleging unfair competition,
false advertising, trade libel, and interference with prospective economic
advantage. On September 19, 1997, Symantec filed a motion to sever Trend's
action against Network Associates from its action against Symantec. Network
Associates did not oppose Symantec's motion to sever, other than to recommend a
joint hearing on patent claim interpretation. On December 19, 1997, the Court
granted Symantec's motion to sever and adopted Network Associates'
recommendation regarding a joint hearing on patent claim interpretation. As a
result of the Court's decision, Trend's actions against Network Associates and
Symantec will proceed separately. The Court has set the date for the joint
patent claim interpretation hearing for September 1998. Thirty days after the
joint patent claim interpretation hearing, the Court has indicated it will set
further dates for discovery and trial.

     On May 6, 1997, RSA Data Security, Inc. ("RSA") filed a lawsuit against
PGP, a wholly owned subsidiary of Network Associates since December 9, 1997, in
San Mateo County Superior Court. RSA seeks a declaration from the court that
certain paragraphs of a license agreement between PGP and Public Key Partners
(the "License Agreement") have been terminated and certain other paragraphs have
survived RSA's purported termination of the License Agreement. RSA, which
purports to act on behalf of Public Key Partners, also seeks an accounting of
PGP's sales of products subject to the License Agreement. PGP denies that RSA
has the authority to act on behalf of Public Key Partners, and denies that the
License Agreement has been breached or terminated in whole or in part. On May
22, 1997, PGP filed a motion to compel arbitration of the action pursuant to an
arbitration



                                       17

<PAGE>   20



clause in the License Agreement. PGP's motion was granted on October 9, 1997.
The Court stayed the state court proceedings and ordered the action to
arbitration.

     On October 14, 1997, RSA filed a patent infringement lawsuit against PGP in
the United States District Court for the Northern District of California. RSA
alleges PGP has infringed one of the patents which was licensed to PGP under the
License Agreement. On November 4, 1997, PGP moved to stay the federal action,
or, in the alternative, compel it to arbitration. On December 23, 1997, RSA
filed a motion to amend its complaint to include Network Associates as
defendant. On March 2, 1998, the court granted PGP's motion to stay the federal
patent action.

     On April 15, 1998, RSA filed a patent infringement lawsuit against Network
Associates in the United States District Court for the Northern District of
California, alleging that Network Associates has infringed the same patent as in
the earlier lawsuit against PGP. Counsel for RSA has orally indicated that RSA
will stipulate to stay this lawsuit on the same basis as the prior lawsuit
against PGP. The Court has scheduled an initial status conference in both cases
for May 11, 1998.

     On May 13, 1998, RSA filed a copyright infringement suit in the United
States District Court for the Northern District of California seeking an
injunction against Network Associates and its Trusted Information Systems
subsidiary from using certain RSA software.

     All four of the above RSA cases were settled on May 29, 1998, and were
dismissed in June, 1998.

     On September 15, 1997, Network Associates was named as a defendant in a
patent infringement action filed by Hilgraeve Corporation ("Hilgraeve") in the
United States District Court for the Eastern District of Michigan. Hilgraeve
alleges that Network Associates' VirusScan product infringes a Hilgraeve patent
which was issued on June 7, 1994. Hilgraeve's action seeks injunctive relief and
unspecified money damages. The case is in discovery. Discovery is presently
scheduled to be completed by December 15, 1998. There is a status conference
scheduled for September 22, 1998. A trial date has been set for June, 1999.

     Although Network Associates intends to defend itself vigorously against the
claims asserted against it in the foregoing actions or matters, there can be no
assurance that such pending litigation will not have a material adverse effect
on the Company's business, financial condition or operating results. The
litigation process is subject to inherent uncertainties and no assurance can be
given that the Company will prevail in any such matters, or will be able to
obtain licenses, on commercially reasonable terms, or at all, under any patents
or other intellectual property rights that may be held valid or infringed by the
Company or its products. Uncertainties inherent in the litigation process
involve, among other things, the complexity of the technologies involved,
potentially adverse changes in the law and discovery of facts unfavorable to the
Company.

     The Company does not typically obtain signed license agreements from its
corporate, government and institutional customers who license products directly
from it. The Company includes an electronic version of a "shrink-wrap" license
in all of its electronically distributed software and a printed license in the
box for its products distributed through traditional distribution channels in
order to protect its copyrights and trade secrets in those products. Since none
of these licenses are signed by the licensee, many authorities believe that such
licenses may not be enforceable under the laws of many states and foreign
jurisdictions. In addition, the laws of some foreign countries either do not
protect proprietary rights or offer only limited protection for those rights.
There can be no assurance that the steps taken by the Company to protect its
proprietary software technology will be adequate to deter misappropriation of
this technology. For example, the Company is aware that a substantial number of
users of its anti-virus products have not paid any registration or license fees
to the Company. Changing legal



                                       18

<PAGE>   21



interpretations of liability for unauthorized use of the Company's software, or
lessened sensitivity by corporate, government or institutional users to avoiding
copyright infringement, could have a material adverse effect on the Company's
business, financial condition and results of operations.

     The Company's principal assets are its intellectual property, and the
Company competes in an increasingly competitive market. There has been
substantial litigation regarding intellectual property rights of technology
companies. The Company has in the past been, and currently is, subject to
litigation related to its intellectual property. There can be no assurance that
there will be no developments arising out of such pending litigation or any
other litigation to which the Company is or may become party which could have a
material adverse effect on the Company's business, financial condition and
results of operation.

     In addition, as the Company may acquire a portion of software included in
its products from third parties, its exposure to infringement actions may
increase because it must rely upon such third parties as to the origin and
ownership of any software being acquired. Similarly, exposure to infringement
claims exists and will increase to the extent that the Company employs or hires
additional software engineers previously employed by competitors,
notwithstanding measures taken by them to prevent usage by such software
engineers of intellectual property used or developed by them while employed by a
competitor. In the future, litigation may be necessary to enforce and protect
trade secrets and other intellectual property rights owned by the Company. The
Company may also be subject to litigation to defend it against claimed
infringement of the rights of others or to determine the scope and validity of
the proprietary rights of others. Any such litigation could be costly and cause
diversion of management's attention, either of which could have a material
adverse effect on the Company's business, financial condition and results of
operations. Adverse determinations in such litigation could result in the loss
of the Company's proprietary rights, subject the Company to significant
liabilities, require the Company to seek licenses from third parties or prevent
the Company from manufacturing or selling its products, any one of which could
have a material adverse effect on the Company's business, financial condition
and results of operations. Furthermore, there can be no assurance that any
necessary licenses will be available on reasonable terms, or at all.

     Risks Related to International Revenue and Activities. In 1997, 1996 and
1995, net revenue from international licenses represented approximately 28%, 24%
and 25%, respectively, of the Company's net revenue. Historically, the Company
has relied primarily upon independent agents and distributors to market its
products internationally. The Company expects that international revenues will
continue to account for a significant percentage of net revenue, with that
percentage increasingly significantly if the pending Dr Solomon acquisition is
consummated. The Company also expects that a significant portion of such
international revenue will be denominated in local currencies. To reduce the
impact of foreign currency fluctuations, the Company uses non-leveraged forward
currency contracts. However, there can be no assurance that the Company's future
results of operations will not be adversely affected by such fluctuations or by
costs associated with currency risk management strategies. Other risks inherent
in international revenue generally include the impact of longer payment cycles,
greater difficulty in accounts receivable collection, unexpected changes in
regulatory requirements, seasonality due to the slowdown in European business
activity during the third quarter, tariffs and other trade barriers,
uncertainties relative to regional economic circumstance (such as the current
economic turbulence in Asia), political instability in emerging markets and
difficulties in staffing and managing foreign operations. There can be no
assurance that these factors will not have a material adverse effect on the
Company's future international license revenue. Further, in countries with a
high incidence of software piracy, the Company may experience a higher rate of
piracy of its products.

     There are a number of additional risks related to the export of the
Company's encryption products. See "-- Risks Relating to Cryptography
Technology."



                                       19

<PAGE>   22



     In addition, a portion of the Company's international revenue is expected
to continue to be generated through independent agents. Since these agents will
not be employees of the Company and will not be required to offer the Company's
products exclusively, there can be no assurance that they will continue to
market the Company's products. Also, the Company is likely to have limited
control over its agents, limited access to the names of the customers to whom
the agents sell its products and limited knowledge of the information provided
by, or representations made by, these agents to its customers.

     Risk of Sabotage. Given the Company's high profile in the security software
market, the Company has been a target of computer "hackers" who have, among
other things, created viruses to sabotage its products or otherwise attack the
Company's products. While to date these efforts have been discovered quickly and
their adverse impact has been limited, there can be no assurance that similar
viruses or efforts will not be created or replicated in the future, that they
will not cause damage to users' computer systems and that demand for the
Company's software products will not suffer as a result. In addition, since the
Company does not control diskette duplication by distributors or its independent
agents, there can be no assurance that diskettes containing the Company's
software will not be infected with viruses.

     Risk of False Detection of Viruses and of Actual or Perceived Security
Breaches. The Company's anti-virus software products have in the past and may at
times in the future falsely detect viruses that do not actually exist. Such
"false alarms," while typical in the industry, may impair the perceived
reliability of the Company's products and may therefore adversely impact market
acceptance of the Company's products. In addition, the Company has in the past
been subject to litigation claiming damages related to a false alarm, and there
can be no assurance that similar claims will not be made in the future.
Similarly, while a well-publicized actual or perceived breach of network or
computer security could trigger a heightened awareness of computer abuse
(resulting in a potential increase in demand for security products) an actual or
perceived breach of network or computer security at one of the Company's
customers, regardless of whether such breach is attributable to the Company's
products, could adversely affect the market's perception of them and their
financial condition or results of operations.

     Risks Relating to Cryptography Technology. Certain of the Company's PGP/TIS
network security products, technology and associated assistance are subject to
export restrictions administered by the U.S. Department of State and the U.S.
Department of Commerce, which permit the export of encryption products only with
the required level of export license. In addition, these U.S. export laws
prohibit the export of encryption products to a number of countries deemed
hostile by the U.S. government. U.S. export regulations regarding the export of
encryption technology require either a transactional export license or the
granting of Department of Commerce Commodity jurisdiction. As result of this
regulatory regime, foreign competitors facing less stringent controls on their
products may be able to compete more effectively than the Company in the global
market. While the Company has obtained approval from the Department of Commerce
to export to certain end users, there can be no assurance that the U.S.
government will approve pending or future export license requests. Further,
there can be no assurance that the list of products and countries for which
export approval is required, and the regulatory policies with respect thereto,
will not be revised from time to time. Failure to obtain the required licenses
or the costs of compliance could have a material adverse effect on the Company's
international revenues.

     Certain of the Company's PGP/TIS network security products are dependent on
the use of public key cryptography technology, which depends in part on the
application of certain mathematical principles known as "factoring." The
security afforded by public key cryptography technology is predicated on the
assumption that the factoring of the composite of large prime numbers is
difficult. Should an easy factoring method be developed, then the security
afforded by encryption products utilizing public key cryptography technology
would be reduced or eliminated. Furthermore, any significant advance in
techniques for attacking cryptographic systems could also render some or all of
the Company's existing products and services obsolete or unmarketable. There can
be no



                                       20

<PAGE>   23



assurance that such developments will not occur. Moreover, even if no
breakthroughs in factoring or other methods of attacking cryptographic systems
are made, factoring problems can theoretically be solved by computer systems
significantly faster and more powerful than those presently available. If such
improved techniques for attacking cryptographic systems are ever developed, it
could have a material adverse effect on the Company's business, operating
results and financial condition.

     Product Liability. The Company's network security and management software
products are used to protect and manage computer systems and networks that may
be critical to organizations and, as a result, the sale and support of these
products by the Company may entail the risk of product liability and related
claims. The Company's license agreements with its customers typically contain
provisions designed to limit the Company's exposure to potential product
liability claims. It is possible, however, that the limitation of liability
provisions contained in these license agreements may not be effective under the
laws of certain jurisdictions, particularly in circumstances involving unsigned
licenses. A product liability claim brought against the Company could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     Dependence upon Key Personnel. The success of the Company will depend to a
significant extent upon a number of key technical and management employees.
While employees are required to sign standard agreements concerning
confidentiality and ownership of inventions, Company employees are generally not
otherwise subject to employment agreements or to noncompetition covenants. The
loss of the services of any key employees could have a material adverse effect
on the Company's business, financial condition and results of operations. The
Company does not maintain life insurance policies on its key employees. The
ability of the Company to achieve its revenue and operating performance
objectives will depend in large part on its ability to attract and retain
technically qualified and highly skilled sales, consulting, technical, marketing
and management personnel. Competition for such personnel is intense and is
expected to remain so for the foreseeable future. There can be no assurance the
Company will be successful in retaining its existing key personnel and in
attracting and retaining the personnel it requires, and failure of the Company
to retain and grow its key employee population could adversely affect the
Company's business and operating results. In early April 1998, Messrs. Leslie
Denend, David Carson and John Stringer resigned from their positions as
executive officers of the Company. Mr. Denend will remain a director of the
Company. Additions of new and departures of existing personnel, particularly in
key positions, can be disruptive and can result in departures of existing
personnel, which could have a material adverse effect upon the Company's
business, operating results and financial condition.

     Customer Purchase Decisions; Potentially Longer Sales and Implementation
Cycles for Certain Products Suites. The products offered by the Company may be
considered to be capital purchases by certain customers or prospective
customers. Capital purchases are often considered discretionary and, therefore,
are canceled or delayed if the customer experiences a downturn in its business
or prospects or as a result of economic conditions in general. Any such
cancellation or delay could adversely affect the Company's results of
operations. In addition, as the Company proceeds with its strategy of selling
product suites under the Net Tools umbrella (particularly to larger enterprise
and national accounts), its sales cycle is likely to lengthen. Such sales may
involve a lengthy education process and a significant technical evaluation and
commitment of capital and other resources and may be subject to the risk of
delays associated with customers' internal budget and other procedures for
approving large capital expenditures, deploying new technologies within their
networks and testing and accepting new technologies that affect key operations.
Because of the potentially lengthy sales cycle and the potentially large size of
such orders, if orders forecasted for a specific customer for a particular
quarter are not realized or revenues are not otherwise recognized in that
quarter, the Company's operating results for that quarter could be materially
adversely affected. See "-- Variability of Quarterly Operating Results" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."



                                       21

<PAGE>   24



     Risks of Doing Business with the U.S. Government. As a result of its recent
acquisition of TIS, the Company expects that, in the near term, a meaningful
portion of its revenues will result from existing and future research and
development contracts with agencies of the U.S. government.

     Network Associates believes that the awarding to it of future government
contracts will in part be dependent upon the continued favorable reaction of
government agencies to the Company's research, development and consulting
capabilities. There can be no assurance that Network Associates will be able to
procure additional government contracts. Minimum fee awards for government
contracts are usually 3% to 7% of the contract costs, but may be as low as 1% of
the contracts costs, and the contracts are subject to cancellation for the
convenience of the governmental agencies. Although the Company has been awarded
contract fees of more than 1% in the past and there have been no terminations of
its government contracts in the past, there can be no assurance that minimum fee
awards or cancellations will not occur in the future. Reductions or delays in
federal funds available for projects the Company is performing could also have
an adverse impact on its government business. Contracts involving the U.S.
government are also subject to the risks of disallowance of costs upon audit,
changes in government procurement policies, the necessity to participate in
competitive bidding and, with respect to contracts involving prime contractors
or government-designated subcontractors, the inability of such parties to
perform under their contracts. Any of the foregoing events could have a material
adverse effect on the Company's financial condition or results of operations.

     Year 2000 Compliance. Many currently installed computer systems and
software products are coded to accept only two digit entries in the date code
field. These date code fields will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, many
companies' software and computer systems may need to be upgraded or replaced in
order to comply with such "Year 2000" requirements. Although the Company
believes that its products and systems are Year 2000 compliant, the Company
utilizes third-party equipment and software that may not be Year 2000 compliant.
Failure of such third-party equipment or software to operate properly with
regard to the Year 2000 and thereafter could require the Company to incur
unanticipated expenses to remedy any problems, which could have a material
adverse effect on the Company's business, operating results and financial
condition. The business, operating results and financial condition of the
Company's customers could be adversely affected to the extent that they utilize
third-party software products which are not Year 2000 compliant. Furthermore,
the purchasing patterns of customers or potential customers may be affected by
Year 2000 issues as companies expend significant resources to correct their
current systems for Year 2000 compliance. These expenditures may result in
reduced funds available to purchase products and services such as those offered
by the Company, which could have a material adverse effect on the Company's
business, operating results and financial condition.

     Supplier Dependence; Third Party Manufacturing. Certain of the Company's
products contain critical components supplied by a single or a limited number of
third parties. The Company has been required to purchase and inventory certain
of the computer platforms around which it designs its network fault and
performance management products to ensure an available supply of the product for
its customers. Any significant shortage of these platforms or other components
or the failure of the third party supplier to maintain or enhance these products
could lead to cancellations of customer orders or delays in placement of orders
which could materially adversely affect the Company's results of operations. If
the Company's purchase of such components or platforms exceeds demand, the
Company could incur losses or other charges in disposing of excess inventory,
which could also materially adversely affect the Company's results of
operations.

     The Company's manufacturing operations consist primarily of final assembly,
testing and quality control of materials, components, subassemblies and systems
for its Sniffer based products. The Company intends to outsource these
manufacturing operations in 1998. There can be no assurance that the Company
will be able to


                                       22

<PAGE>   25



qualify and secure on commercially acceptable terms satisfactory third party
manufacturers on a timely basis or at all. In addition, reliance on third party
manufacturers will involve a number of risks, including the lack of direct
control over the manufacturing process, the absence or unavailability of
adequate capacity and reduced control over delivery schedules, quality control
and costs. In the event that, once initially secured, the Company's third party
manufacturers are unable or unwilling to continue to manufacture the Sniffer
based products in required volumes, on a cost effective basis, in a timely
manner or at all, the Company will have to secure additional manufacturing
capacity. Even if such additional capacity is available at commercially
acceptable terms, the qualification process could be lengthy and could create
delay in product shipments.

     Effect of Certain Provisional Anti-Takeover Effects of Certificate of
Incorporation, Bylaws and Delaware Law. The Board of Directors of the Company
has the authority to issue up to 5,000,000 shares of Preferred Stock and to
determine the price, rights, preferences, privileges and restrictions, including
voting rights, of those shares without any further vote of action by its
stockholders. The rights of the holders of Company Common Stock is subject to,
and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. The issuance of Preferred Stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire a majority of the outstanding voting stock. Further,
certain provisions of Delaware law and the Company's Certificate of
Incorporation and Bylaws, such as a classified board, could delay or make a more
difficult a merger, tender offer or proxy contest involving the Company. While
such provisions are intended to enable the Company's Board to maximize
stockholder value, they may have the effect of discouraging takeovers which
could be in the best interest of certain stockholders. There is no assurance
that such provisions will not have an adverse effect on the market value of the
Company's Common Stock.

                              SELLING STOCKHOLDERS

     The following table lists the Selling Stockholders and the number of shares
of the Company's Common Stock which each owned or had the right to acquire as of
August 6, 1998. Because the Selling Stockholders may offer all or some of the
Shares which they hold pursuant to the offering contemplated by this Prospectus,
and because there are currently no agreements, arrangements or understandings
with respect to the sale of any of the Shares, no estimate can be given as to
the amount of Shares that will be held by the Selling Stockholders after
completion of this offering. The Shares are being registered to permit public
secondary trading of the Shares, and the Selling Stockholders may offer the
Shares for resale from time to time. See "Plan of Distribution."

     The Shares being offered by the Selling Stockholders were acquired from the
Company in connection with, (i) the Company's acquisition of 100% of the issued
share capital of Anyware (the "Anyware Acquisition"), and (ii) the Company's
acquisition of 100% of the issued share capital of CSB (the "CSB Acquisition").
The Anyware Acquisition was accomplished pursuant to the terms of a Stock
Purchase Agreement, dated as of July 30, 1998, whereby the Company acquired all
of the issued and outstanding share capital of Anyware in exchange for 228,204
shares of Company Common Stock. The CSB Acquisition was accomplished pursuant to
the terms of a Share Purchase Agreement, dated as of June 29, 1998, whereby the
Company acquired all of the issued and outstanding share capital of CSB in
exchange for 9,815 shares of Company Common Stock.

     The Company has filed with the Commission, under the Act, a Registration
Statement on Form S-3, of which this Prospectus forms a part, with respect to
the resale of the Shares from time to time on the Nasdaq National Market or in
privately-negotiated transactions. The Company has agreed to use reasonable
efforts to keep such Registration Statement effective for 180 days from the date
of effectiveness of the Registration Statement on Form S-3, of which this
Prospectus forms a part, subject to certain restrictions, or, if earlier, until
the distribution contemplated in this Prospectus has been completed.

                              PLAN OF DISTRIBUTION

     All or a portion of the Shares offered hereby by the Selling Stockholders
may be delivered and/or sold from time to time in transactions on the Nasdaq
National Market, in privately negotiated transactions, or by a combination of
such methods of sale, at fixed prices that may be changed, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices or at negotiated prices. After the effectiveness of the Registration
Statement of which this Prospectus is a part, the Selling Stockholders may make
short sales of the Company's Common Stock and may use the Shares to cover the
resulting short positions. The Selling Stockholders may effect such transactions
by selling the Shares to or through broker-dealers and such broker-dealers may
receive compensation in the form of discounts, concessions or commissions from
the Selling Stockholders or the purchasers of the Shares for whom such
broker-dealers may act as agent or to whom they sell as principal or both (which
compensation to a particular broker-dealer might be in excess of customary
commissions). There is no assurance that any of the Selling Stockholders will
sell any or all of the Shares offered by them.

     Any Selling Stockholder and any broker-dealers that participate in the
distribution may under certain circumstances be deemed to be "underwriters"
within the meaning of the Securities Act, and any commissions received by such
broker-dealers and any profits realized on the resale of Shares may be deemed to
be underwriting discounts and commissions under the Securities Act. Each Selling
Stockholder may agree to indemnify such broker-dealers against certain
liabilities, including liabilities under the Securities Act. In addition, the
Company has agreed to indemnify in certain circumstances certain Selling
Stockholders against certain liabilities, including liabilities arising under
the Securities Act and Exchange Act. Certain Selling Stockholders have agreed to
indemnify in certain circumstances the Company and certain related persons
against certain liabilities, including liabilities arising under the Securities
Act and Exchange Act.

     Any broker-dealer participating in such transactions as agent may receive
commissions from a Selling Stockholder (and, if it acts as agent for the
purchase of such Shares, from such purchaser). Broker-dealers may agree with
such Selling Stockholder to sell a specified number of Shares at a stipulated
price per share, and, to the extent such a broker-dealer is unable to do so
acting as agent for such Selling Stockholder, to purchase as principal any
unsold Shares. Broker-dealers who acquire Shares as principal may thereafter
resell such Shares from time to time in transactions (which may involve crosses
and block transactions and which may involve sales to and through other
broker-dealers, including transactions of the nature described above) on the
Nasdaq National Market, in privately negotiated transactions, or by a
combination of such methods of sale, at fixed prices that may be changed, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated



                                       24

<PAGE>   27



prices, and in connection with such resales may pay to or receive from the
purchasers of such Shares commissions computed as described above.

     Each Selling Stockholder will be subject to applicable provisions of the
Exchange Act, and the rules and regulations thereunder, including, without
limitation, Regulation M, which provisions may limit the time of bids for and
purchases of shares of the Company's Common Stock by such Selling Stockholder.

     Each Selling Stockholder will pay all commissions and other expenses
associated with the sale of the Shares by such Selling Stockholder. The Shares
offered hereby are being registered pursuant to contractual obligations of the
Company, and the Company has agreed to bear certain expenses in connection with
the registration and sale of the Shares being offered by every such Selling
Stockholder. The Company has not made any underwriting arrangements with respect
to the sale of Shares offered hereby.

                                 USE OF PROCEEDS

     The Company will not receive any proceeds from the sale of Common Stock by
the Selling Stockholders.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Company's Second Restated Certificate of Incorporation, as amended,
limits, to the maximum extent permitted by Delaware law, the personal liability
of directors for monetary damages for breach of their fiduciary duties as a
director. The Company's Restated Bylaws provide that the Company shall indemnify
its officers and directors and may indemnify its employees and other agents to
the fullest extent permitted by Delaware law. The Company has entered into
indemnification agreements with its officers and directors containing provisions
which are in some respects broader than the specific indemnification provisions
contained in the Delaware General Corporation Law. The indemnification
agreements require the Company, among other things to indemnify such officers
and directors against certain liabilities that may arise by reason of their
status or service as directors or officers (other than liabilities arising from
willful misconduct of a culpable nature), to advance their expenses incurred as
a result of any proceeding against them as to which they could be indemnified,
and to obtain directors' and officers' insurance, if available on reasonable
terms. The Company believes that these agreements are necessary to attract and
retain qualified persons as directors and officers.

     Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify a director, officer, employee or agent made a party to
an action by reason of that fact that he or she was a director, officer,
employee or agent of the corporation or was serving at the request of the
corporation against expenses actually and reasonably incurred by him or her in
connection with such action if he or she acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the corporation and with respect to any criminal action, had no reasonable cause
to believe his or her conduct was unlawful.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Registrant
pursuant to the foregoing provisions, the Registrant has been informed that in
the opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable.

ITEM 15.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     Section 145 of the Delaware General Corporation law ("DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceedings, whether civil, criminal, administrative or investigative (other
than action by or in the right of such corporation), by reason of the fact that
such person was an officer or director of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided that such officer or director acted in good faith and in a
manner he reasonably believed to be in or not opposed to the corporation's best
interest, and, for criminal proceedings, had no reasonable cause to believe his
conduct was illegal. A Delaware corporation may indemnify officers and directors
in an action by or in the right of the corporation under the same conditions,
except that no indemnification is permitted without judicial approval if the
officer or director is adjudged to be liable to the corporation in the
performance of his duty. Where an officer or director is successful on the
merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses which such officer or
director actually and reasonably incurred.

     In accordance with the DGCL, the Company's Second Restated Certificate of
Incorporation, as amended (the "Certificate"), contains a provision to limit the
personal liability of the directors of the Registrant for violations of their
fiduciary duty. This provision eliminates each director's liability to the
Registrant or its stockholders for monetary damages except (i) for any breach of
the director's duty of loyalty to the Registrant or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL providing for
liability of directors for unlawful payment of dividends or unlawful stock
purchases or redemptions, or (iv) for any transaction from which a director
derived an improper personal benefit. The effect of this provision is to
eliminate the personal liability of directors for monetary damages for actions
involving a breach of their fiduciary duty of care, including any such actions
involving gross negligence.

<PAGE>   31



     Article Sixth of the Company's Certificate and Article VIII, Section 1 of
the Company's Restated Bylaws provide for indemnification of the officers and
directors of the Registrant to the fullest extent permitted by applicable law.

     The Registrant has entered into indemnification agreements with each
director and executive officer which provide indemnification to such directors
and executive officers under certain circumstances for acts or omissions which
may not be covered by directors' and officers' liability insurance.

ITEM 17.  UNDERTAKINGS.

     The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement: (i) to include any
prospectus required by section 10(a)(3) of the Securities Act; (ii) to reflect
in the prospectus any facts or events arising after the effective date of the
Registration Statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information set forth in the Registration Statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) (Section 230.424(b) of this chapter) if, in
the aggregate, the changes in volume and price represent no more than a 20%
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and (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; provided, however, that (i) and
(ii) do not apply if the Registration Statement is on Form S-3, Form S-8 or Form
F-3, and the information required to be included in a post-effective amendment
by (i) and (ii) is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act, 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.

     The undersigned 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 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.

     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 described in Item 15 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against liabilities (other than the payment of the
Registrant of 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 to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes that:



                                      II-3

     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

     (2) For the purpose of determining liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus 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.

of this Agreement, Buyer agrees to purchase (the "PURCHASE") from each of the
Sellers, and each of the Sellers agrees to sell to Buyer, all Company Shares

Agreement and the transactions contemplated hereby, NAI (i) assumes all
responsibilities, obligations, and liabilities of Buyer as if NAI were in fact
Buyer and (ii) will cause Buyer to perform its obligations hereunder.

2(e) and Article VII, NAI hereby delivers to the Sellers at the Closing the
number of shares of NAI Common Stock equal to (i) $10,654,255 (USD) divided by

set forth in Schedule I hereto. The shares of NAI Common Stock paid in respect
of the Purchase Price shall be registered under the United States Securities Act
of 1933, as amended, in accordance with the provisions of the Registration
Rights Agreement attached hereto as Exhibit B-1.

this Agreement (the "CLOSING") shall take place at the offices of B Cremades Y
Asociados, Goya 18, Madrid, Spain or such other place as NAI and Sellers
mutually determine, upon the satisfaction or waiver of all conditions to the
obligations of the Parties to consummate the transactions contemplated hereby
(other than conditions with respect to actions the respective Parties will take

determine (the "CLOSING DATE).

            (d)   Deliveries at the Closing; Transfer of Title. At the Closing,

ownership and title to the Shares shall pass from the Sellers to Buyer upon the
execution of this Agreement by each Party. To that extent, the Sellers shall
sign before the notary public and then deliver the Transfer Deed in the form
attached as Exhibit B-6, as well as all other documents, if any, required for
the valid and effective transfer and registration of the title to the Shares in
the name of Buyer. It is understood that the Transfer Deed is signed only in

<PAGE>   11
Article VII hereof, the full unencumbered ownership and title to the shares of
NAI Common Stock to be issued pursuant to this Agreement shall pass to Sellers
upon the execution of this Agreement by each Party.

            (e)   Escrow Deposit. At the Closing, from the Purchase Price
otherwise payable pursuant to this Article II, NAI shall deposit on behalf of
Sellers each of the General Escrow Amount and the Special Escrow Amount into
separate escrow accounts pursuant to Article VII hereof. The portion of such
escrowed amounts contributed on behalf of each Seller shall be in proportion to
such Seller's Proportionate Escrow Interest.

            (f)   Purchase Price Adjustment. The Purchase Price will be subject
to adjustment as follows:

                  (i)   Closing Balance Sheet. As soon as practicable following
the Closing, the Company will, at the expense of NAI and Buyer, prepare and
cause to be audited by Coopers & Lybrand L.L.P., or its successor, if any,
independent accountants, and the Company will deliver to NAI and each of the
Sellers, a balance sheet of the Company as of the Closing Date (the "CLOSING
BALANCE SHEET"). The Closing Balance Sheet will be prepared in accordance with
GAAP consistent with the basis of accounting and procedures and methods employed
by the Company in its Financial Statements, as defined in Section 4(g) below.
During the conduct of the audit, the Company will cooperate in all respects with
the independent auditors for the purposes of completing the Closing Balance
Sheet. In addition, the Company and the independent auditors shall be available
for periodic inquiry by NAI, the Sellers and the Company, and the independent
auditors will answer such questions as NAI or the Sellers may have and provide
such additional schedules and materials as NAI or the Sellers may reasonably
request in order to permit a meaningful review of the Closing Balance Sheet.

                  (ii)  Definition. "TANGIBLE NET WORTH" will mean the aggregate
of all tangible assets (net of all reserves and excluding all intangible assets,
including without limitation, all goodwill and capitalized software), less all
liabilities of any kind (including without limitation accounts payable,
royalties payable, warranty reserves, accrued bonuses, accrued vacation,
employee expense obligations, deferred revenue, litigation reserves and debt and
other liabilities) determined in accordance with GAAP and the considerations
specified in Section 4(g) of the Sellers Disclosure Schedule. For purposes of
determining Tangible Net Worth, all reserves in respect of bad debts or doubtful
accounts shall be excluded from (i.e., will not reduce) Tangible Net Worth.

                  (iii) Disputes. At any time within 30 days following the
delivery of the Closing Balance Sheet to NAI and each of the Sellers (the
"REVIEW PERIOD"), NAI or both Sellers may dispute any amounts reflected or not
reflected on the Closing Balance Sheet to the extent the net effect of all such
disputed amounts in the aggregate would affect the Tangible Net Worth amount,
but only on the basis that such amounts were not arrived at in accordance with
Section 2(f)(i); each of NAI and both Sellers will notify the other in writing
of each such disputed item, and will specify the amount thereof in dispute, not
later than the expiration of the Review Period. If NAI and the Sellers are able
to resolve all the disputed items, then the Closing Balance Sheet agreed upon by
NAI and the Sellers will be final, binding and conclusive on the parties hereto.
If NAI and the Sellers are unable to resolve any disputed 


                                      -6-
<PAGE>   12
item and are therefore unable to agree as to the Closing Balance Sheet and the
resultant Tangible Net Worth amount within 20 days following the expiration of
the Review Period, then within 10 days thereafter either NAI or both Sellers may
elect that the items remaining in dispute be submitted for resolution to a "Big
Five" accounting firm in Spain (excluding NAI's and Company's independent
accountants and the member of which who will be primarily responsible for
resolving such disputes will have had substantial auditing experience and
substantial experience in arbitration or other dispute resolution proceedings
concerning accounting issues) selected by mutual agreement of NAI and the
Sellers (or failing such agreement, appointed by the American Arbitration
Association) (the "ACCOUNTANTS"). The Accountants will, within 30 days after
submission, determine, based solely on presentations by NAI and the Sellers (and
their representatives) and not by independent review, and render a written
report to the parties upon, such remaining disputed items and the resultant
calculation of the Closing Balance Sheet and the Tangible Net Worth amount in
accordance with the provisions hereof, and such report and the resultant Closing
Balance Sheet will be final, binding and conclusive on the parties hereto. In
resolving any disputed item, the Accountants may not assign a value to such item
greater than the greatest value for such item claimed by either party or less
than the smallest value for such item claimed by either party. The fees and
disbursements of the Accountants (and of the American Arbitration Association,
if any) (a) will be paid out of the General Escrow Fund established under
Article VII if the Tangible Net Worth amount finally determined pursuant to this
Section 2(f)(i) shall be more than $25,000 (USD) below the Tangible Net Worth
amount reflected on the Closing Balance Sheet originally submitted pursuant to
Section 2(f)(i) hereof, or (b) will be borne by NAI if the Tangible Net Worth
amount finally determined pursuant to this Section 2(f)(i) is less than $25,000
(USD) below the Tangible Net Worth amount reflected on the Closing Balance Sheet
originally submitted pursuant to Section 2(f)(i) hereof. NAI and the Sellers
hereby agree to cooperate and work in good faith and as expeditiously as
reasonably possible to resolve any and all Closing Balance Sheet disputes.

                  (iv)  Adjustment. In the event that the Tangible Net Worth of
the Company as of the Closing Date as reported in the Closing Balance Sheet is
less than PTAS 226,250,000 (or the equivalent amount of US dollars determined
according to the representative rate of exchange on the second full trading day
immediately prior to the closing of the Purchase as published in the Spanish
Official State Gazette), then the Purchase Price shall be reduced (based on the
Determined Price), and the amounts payable to the Sellers shall be reduced, to
the extent of such deficiency. NAI shall provide written notice of such
deficiency to the Escrow Agent pursuant to the provisions of Article VII, and
the deficiency shall be payable to the NAI from the General Escrow Account as an
escrow claim thereunder (pursuant to the procedure set forth in such Article
VII, except that no objection may be made by Sellers to a claim submitted
following the resolution of a dispute pursuant to Section 2(f)(iii)).

                                  ARTICLE III

      3.    Representations and Warranties Concerning the Transaction.

            (a)   Representations and Warranties of the Sellers. Each of the
Sellers severally (but not jointly) represents and warrants to NAI and Buyer
that the statements contained in this Section 3(a) are correct and complete as
of the date of this Agreement and will be correct and complete as of the Closing
Date (as though made then and as though the Closing Date were substituted for

                                      -7-
<PAGE>   13
Agreement throughout this Section 3(a)) with respect to himself, except as set
forth in the Sellers Disclosure Schedule attached hereto.)

      and authority to execute and deliver this Agreement and to perform his
      obligations hereunder. This Agreement constitutes the valid and legally
      binding obligation of each Seller, enforceable in accordance with its
      terms and conditions. None of the Sellers need give any notice to, make
      any filing with, or obtain any authorization, consent, or approval of any
      government or governmental agency in order to consummate the transactions
      contemplated by this Agreement.

                  (ii)  Noncontravention. Neither the execution and the delivery
      of this Agreement, nor the consummation of the transactions contemplated
      hereby, will (A) violate any constitution, statute, regulation, rule,
      injunction, judgment, order, decree, ruling, charge, or other restriction
      of any government, governmental agency, or court to which any Seller is
      subject or (B) conflict with, result in a breach of, constitute a default
      under, result in the acceleration of, create in any party the right to
      accelerate, terminate, modify, or cancel, or require any notice under any
      agreement, contract, lease, license, instrument, or other arrangement to
      which any Seller is a party or by which he is bound or to which any of his
      assets is subject.

                  (iii) Brokers' Fees. None of the Sellers has any Liability or
      obligation to pay any fees or commissions to any broker, finder, or agent
      with respect to the transactions contemplated by this Agreement or the
      Collateral Documents for which NAI or Buyer could become liable or
      obligated.

                  (iv)  Company Shares. Each Seller holds of record and owns
      beneficially the number of Company Shares set forth next to his name on
      Schedule I, free and clear of any restrictions on transfer (other than any
      restrictions under the Securities Act and state securities laws), Taxes,
      Security Interests, options, warrants, purchase rights, contracts,
      commitments, equities, claims, and demands. None of the Sellers is a party
      to any option, warrant, purchase right, or other contract or commitment
      that could require any Seller to sell, transfer, or otherwise dispose of
      any capital stock of the Company (other than this Agreement). None of the
      Sellers is a party to any voting trust, proxy, or other agreement or

set forth in the disclosure schedule delivered by the Sellers to NAI on the date

      accrued. The Company is not currently the beneficiary of any extension of
      time within which to file any Tax Return. No claim has ever been made by
      an authority in a jurisdiction where the Company does not file Tax Returns
      that it is or may be subject to taxation by that jurisdiction. There are
      no Security Interests on any of the assets of the Company that arose in

      concerning any Tax Liability of the Company either (A) claimed or raised
      by any authority in writing or (B) as to which any of the Sellers and the
      directors and officers (and employees responsible for Tax matters) of the
      Company has Knowledge based upon personal contact with any agent of such
      authority. Section 4(k) of the Sellers Disclosure Schedule lists all
      national, provincial, federal, state, regional, local, and foreign income
      Tax Returns filed with respect to the Company for taxable periods with
      respect to which the applicable statute of limitations has not expired

      indicates those Tax Returns that have been audited, and indicates those
      Tax Returns that currently are the subject of audit. The Sellers have
      delivered to NAI correct and complete copies of all Tax Returns,
      examination reports, and statements of deficiencies assessed against or
      agreed to by the Company with respect to the foregoing taxable periods.

                  (iv)  The Company has not waived any statute of limitations in
      respect of Taxes or agreed to any extension of time with respect to a Tax
      assessment or deficiency.

                  (v)   The unpaid Taxes of the Company (A) did not, as of the
      Most Recent Fiscal Month End, exceed the reserve for Tax Liability (rather
      than any reserve for deferred Taxes established to reflect timing
      differences between book and Tax income) set forth on the face of the Most
      Recent Financial Statements (rather than in any notes thereto) and (B) do
      not exceed that reserve as adjusted for the passage of time through the
      Closing Date in accordance with the past custom and practice of the
      Company in filing its Tax Returns.

            applicable laws.

                        (B)   All required reports and descriptions have been
            timely filed and distributed appropriately with respect to each such

            contributions and employee salary reduction contributions) which are
            due have been paid to each such Employee Benefit Plan and all

                        (D)   There have been no prohibited transactions with
            respect to any such Employee Benefit Plan. No fiduciary has any
            Liability for breach of fiduciary duty 


                                      -21-

            or any other failure to act or comply in connection with the
            administration or investment of the assets of any such Employee
            Benefit Plan. No action, suit, proceeding, hearing, or investigation
            with respect to the administration or the investment of the assets
            of any such Employee Benefit Plan (other than routine claims for

            directors and officers (and employees with responsibility for
            employee benefits matters) of the Company has any Knowledge of any

      or otherwise), including any investigatory, remedial or corrective
      obligations, relating to any of them or its facilities arising under
      Environmental, Health, and Safety Requirements.

                  (iii) No facts, events or conditions relating to the past or
      present facilities, properties or operations of the Company will prevent,

      Safety Requirements, give rise to any investigatory, remedial or
      corrective obligations pursuant to Environmental, Health, and Safety

                                   ARTICLE V

      5.    Post-Closing Covenants. The Parties agree as follows with respect to
the period following the Closing.

            (a)   General. In case at any time after the Closing any further
action is necessary or desirable to vest Buyer with full right, title and
possession to the Purchased Shares or otherwise carry out the purposes of this
Agreement and the Collateral Documents (including the transfer to the Company of
any Intellectual Property used or purported to be used by the Company in the
conduct of its business prior to the Closing Date), each of the Parties will
take such further action (including the execution and delivery of such further
instruments and documents) as any other Party reasonably may request, all at the
sole cost and expense of the requesting Party (unless the requesting Party is
entitled to indemnification therefor under Article VII below). Further, the
officers and directors of the Company are fully authorized in the name of the
Company or otherwise to take, and will take, all such lawful and necessary
and/or desirable action so long as such action is consistent with this
Agreement.

            (b)   Litigation Support. In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving the Company, each of the other Parties will
cooperate with him or it and his or its counsel in the contest or defense, make
available their personnel, and provide such testimony and access to their books
and records as shall be necessary in connection with the contest or defense, all
at the sole cost and expense of the contesting or defending Party (unless the
contesting or defending Party is entitled to indemnification therefor under
Article VII below).

            (c)   Transition. None of the Sellers will take any action that is
designed or intended to have the effect of discouraging any lessor, licensor,
customer, supplier, or other business associate of the Company from maintaining
the same business relationships with the Company after the Closing as it
maintained with the Company prior to the Closing.

            (d)   Confidentiality. Each of the Sellers, NAI and Buyer will treat
and hold as such all of the Confidential Information, refrain from using any of
the Confidential Information except in connection with this Agreement and the
Collateral Documents, and deliver promptly to the other Party or destroy, at the
request and option of the other Party, all tangible embodiments (and all copies)
of the Confidential Information which are in his or its possession. In the event
that any of the Parties is requested or required (by oral question or request
for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand, or similar process) to disclose any Confidential
Information, then the party receiving such request will notify the other Party
promptly of the request or requirement so that the other Party may seek an
appropriate protective order or waive compliance with the provisions of this
Section 5(d). If, in the absence of a protective order or the receipt of a
waiver hereunder, any of the Parties is, on the advice of counsel, compelled to
disclose any Confidential 


                                      -24-
<PAGE>   30
Information to any tribunal or else stand liable for contempt, that Party may
disclose the Confidential Information to the tribunal; provided, however, that
the disclosing Party shall use his or its reasonable best efforts to obtain, at
the reasonable request of the other Party, an order or other assurance that
confidential treatment will be accorded to such portion of the Confidential

                                  ARTICLE VII

      7.    Remedies for Breaches of This Agreement.

            (a)   Survival of Representations and Warranties. All of the
covenants, representations and warranties of the Parties contained in this
Agreement shall survive the Closing hereunder (even if the damaged Party knew or

the time of Closing) and continue in full force and effect until March 31, 1999.
The foregoing shall not limit the provisions with respect to the Special Escrow
Fund.

            (b)   Indemnification Provisions. The indemnification provisions

equitable, or civil law remedy under Spanish law (including without limitation
any such remedy arising under Environmental, Health, and Safety Requirements)
any Party may have with respect to the Company, or the transactions contemplated
by this Agreement. Each of the Sellers hereby agrees that he or it will not make
any claim for indemnification against the Company by reason of the fact that he
or it was a director, officer, employee, or agent of any such entity or was
serving at the request of any such entity as a partner, trustee, director,
officer, employee, or agent of another entity (whether such claim is for
judgments, damages, penalties, fines, costs, amounts paid in settlement, losses,
expenses, or otherwise and whether such claim is pursuant to any statute,
charter document, bylaw, agreement, or otherwise) with respect to any action,
suit, proceeding, complaint, claim, or demand brought by NAI or Buyer against
such Seller (whether such action, suit, proceeding, complaint, claim, or demand
is pursuant to this Agreement, applicable law, or otherwise).

            (c)   Escrow Arrangements.

                  (i)   Escrow Funds.

                        (A)   General. As provided in Section 2(f), at Closing,
            on behalf of the Sellers, NAI shall deposit with Greater Bay Trust
            Company, as Escrow Agent (the "ESCROW AGENT"), the General Escrow
            Amount, which shall constitute a general escrow fund (the "GENERAL
            ESCROW FUND") and the Special Escrow Amount, which shall constitute
            a special escrow fund (the "SPECIAL ESCROW FUND") each to be
            governed by the terms set forth herein (the General Escrow Fund and
            the Special Escrow Fund together the "ESCROW FUNDS"). The portion of
            the General Escrow Amount and the Special Escrow Amount contributed
            by NAI on behalf of each Seller, as applicable, shall correspond to
            such Seller's Proportionate Escrow Interest. Each Seller shall be
            entitled to all voting rights with respect to any NAI Common Stock
            held in escrow on his behalf.

                        (B)   General Escrow Fund. The General Escrow Fund shall
            be available to compensate NAI and its Subsidiaries for (i) any
            claim, loss, expense, liability or other damage, including
            reasonable attorneys' fees, costs of investigation and disbursements
            in connection with any action, suit or proceeding, to the extent of
            the amount of such claim, loss, expense, liability or other damage
            (collectively "LOSSES") that NAI and its Subsidiaries or any of
            their affiliates 


                                      -27-
<PAGE>   33
            has incurred (or, in the case of an extension of the General Escrow
            Period pursuant to Section 7(c)(ii), reasonably anticipates
            incurring), by reason of the breach by the Sellers of any
            representation, warranty, covenant or agreement of the Sellers
            contained herein or in any Collateral Document or the Sellers
            Disclosure Schedule; (ii) any accounts receivable that are
            outstanding as of the Closing Date as determined in the Closing
            Balance Sheet that are uncollected subsequent to the Closing Date;
            and (iii) payment of any Losses otherwise agreed to be paid by
            Sellers (including as set forth in the Sellers Disclosure Schedule);
            provided, however, that (x) solely for purposes of determining
            whether a breach of any representation or warranty or covenant has
            occurred, and the amount of any Losses attributable to any such
            breach, any qualification as to materiality set forth therein shall
            not be given effect; and (y) claims for Losses incurred as a result
            of a breach by a Seller of any of the representations set forth in
            Section 3(a) shall be satisfied out of such Seller's Proportionate
            Interest of the General Escrow Fund until such Proportionate Escrow
            Interest is exhausted, and then shall be satisfied out of the
            General Escrow Fund in accordance with this Agreement.
            Notwithstanding the foregoing, with respect to Losses contemplated
            in clause (i) above, NAI and its Subsidiaries shall not be entitled
            to receive any disbursement or cause any amount to be retained in
            the General Escrow Fund with respect to any Losses arising in
            respect of any individual occurrence or circumstance unless the
            amount of such Losses shall exceed $10,000 (USD), provided that in
            the event that the aggregate amount of such Losses of NAI and its
            Subsidiaries shall exceed $40,000 (USD) (without regard to the
            foregoing $10,000 (USD) limitation), then NAI or its Subsidiaries
            shall be entitled to recover from the General Escrow Fund all such
            Losses (without regard to the individual $10,000 (USD) limitations).

                        (C)   Special Escrow Fund. The Special Escrow Fund shall
            be available to compensate NAI and its Subsidiaries for any Losses
            ("SPECIAL LOSSES") that NAI and its Subsidiaries or any of their
            affiliates has incurred (or in the case of an extension of the
            Special Escrow Period pursuant to Section 7(c)(ii), reasonably
            anticipates incurring) by reason of the Special Tax Matters.
            "SPECIAL TAX MATTERS" means the Company's Intellectual Property
            license arrangements in place prior to the Closing Date and
            terminated on the Closing Date pursuant to Section 6(a)(viii) in
            connection with (i) both the royalty payments and the definitive
            transfer of said Intellectual Property; (ii) the Value Added Tax, if
            any, payable in connection with the Company's royalty payments; and
            (iii) any withholding taxes or other personal income taxes as well
            as any corporate tax impact thereof in connection with the amounts
            paid to the Company's employees including but not limited to those
            paid as out-of-pocket and travel expenses.

                  (ii)  Escrow Periods; Distribution upon Termination of Escrow
      Periods. Subject to the following requirements, the General Escrow Fund
      shall remain in existence until March 31, 1999 (the "GENERAL ESCROW
      PERIOD") and the Special Escrow Fund shall remain in existence until the
      lapsing of the applicable statute of limitations in respect of relevant
      Taxes attributable to the Special Tax Matters (the "SPECIAL ESCROW
      PERIOD"), in each case, subject to extension as set forth below. At the
      expiration of the General Escrow Period, the General Escrow Fund shall be
      released from escrow to the Sellers, in an amount equal to the entire
      initial General Escrow Fund less an amount equal to the sum of (i) all
      amounts theretofore paid out of 


                                      -28-
<PAGE>   34
      the General Escrow Fund to NAI and its Subsidiaries pursuant to this
      Article VII, (ii) an amount equal to such portion of the General Escrow
      Fund which, in the reasonable judgment of NAI, subject to the objection of
      both Sellers (and the subsequent arbitration of the matter in the manner
      provided in Section 7(c)(vii) hereof), is necessary to satisfy any
      unsatisfied claims specified in any Officer's Certificate theretofore
      delivered to the Escrow Agent prior to the end of the General Escrow
      Period (which amount shall remain in the General Escrow Fund (and which
      shall cause the General Escrow Fund shall remain in existence) until such
      claims have been resolved). At the expiration of the Special Escrow
      Period, the Special Escrow Fund shall be released from escrow to the
      Sellers, in an amount equal to the entire initial Special Escrow Fund less
      an amount equal to the sum of (i) all amounts theretofore paid out of the
      Special Escrow Fund to NAI and its Subsidiaries pursuant to this Article
      VII, (ii) all amounts theretofore paid out of the Special Escrow Fund to
      Sellers pursuant to Section 7(c)(iii) below and (iii) an amount equal to
      such portion of the Special Escrow Fund which, in the reasonable judgment
      of NAI, subject to the objection of both Sellers (and the subsequent
      arbitration of the matter in the manner provided in Section 7(c)(vii)
      hereof), is necessary to satisfy any unsatisfied claims specified in any
      Officer's Certificate theretofore delivered to the Escrow Agent prior to
      the end of the Special Escrow Period (which amount shall remain in the
      Special Escrow Fund (and which shall cause the Special Escrow Fund shall
      remain in existence) until such claims have been resolved). As soon as all
      such claims have been resolved following the end of the General Escrow
      Period and the Special Escrow Period, as applicable, the Escrow Agent
      shall deliver to the eligible Sellers the remaining portion of the General
      Escrow Fund and Special Escrow Fund, as applicable, not required to
      satisfy such claims. Deliveries of escrowed amounts to the Sellers
      pursuant to this Section shall be made according to each Seller's
      Proportionate Escrow Interest as certified to the Escrow Agent by the
      Sellers.

                  (iii) Interim Distributions from Special Escrow Fund. Promptly
      following each of the dates set forth on Schedule 7(c)(iii), the Escrow
      Agent shall cause to be paid to the eligible Sellers (in accordance with
      their Proportionate Escrow Interest) an amount equal to the entire initial
      Special Escrow Fund less an amount equal to the sum of (i) the minimum
      Special Escrow Amount indicated on Schedule 7(c)(iii) in respect of such
      indicated date and (ii) the aggregate amount of all unsatisfied good faith
      claims by NAI and its Subsidiaries against the Special Escrow Fund
      (subject to arbitration of the matter in the manner provided in Section
      7(c)(vii)) not yet paid by the Escrow Agent prior to such date to the
      extent and amount of any Tax dispute or challenge. Notwithstanding the
      foregoing, (without duplication) no distribution shall be payable with
      respect to any particular date if, the Company or the Sellers shall have
      been notified of, any Tax investigation, dispute or challenge related to
      the relevant Tax Period and related Special Tax Matters or any act by the
      applicable tax authority which could serve to toll the expiration of the
      applicable statute of limitations.

                  (iv)  Protection of Escrow Funds. The Escrow Agent shall hold
      and safeguard the Escrow Funds during the applicable escrow period, shall
      treat such fund as a trust fund in accordance with the terms of this
      Agreement and not as the property of NAI and shall hold and dispose of the
      Escrow Funds only in accordance with the terms hereof.


                                      -29-
<PAGE>   35
                  (v)   Claims Upon Escrow Funds. Upon receipt by the Escrow
      Agent at any time on or before the last day of the General Escrow Period
      or Special Escrow Period, as applicable, of a certificate signed by any
      officer of NAI (an 'OFFICER'S CERTIFICATE'): (A) stating that NAI or its
      Subsidiaries has incurred and paid or properly accrued Losses or Special
      Losses, as applicable (or reasonably anticipates that it may have to pay
      or accrue Losses or Special Losses, as applicable), and (B) specifying in
      reasonable detail the individual items of Losses or Special Losses, as
      applicable, included in the amount so stated, the date each such item was
      incurred and paid or properly accrued, or the basis for such anticipated
      liability, and in the case of Losses the nature of the misrepresentation,
      breach of warranty or claim to which such item is related, the Escrow
      Agent shall, subject to the provisions of Section 7(c)(vi) and 7(c)(vii)
      hereof, deliver, as promptly as practicable, to NAI or its Subsidiaries
      out of the General Escrow Fund or Special Escrow Fund, as applicable, such
      amounts held in the applicable Escrow Fund equal to such Losses or Special
      Losses. NAI shall submit an Officer's Certificate only in good faith.
      Claims in respect of Special Losses shall be made in accordance with the
      additional provisions set forth in Section 7(c)(v) of the NAI Disclosure
      Schedule. NAI or its Subsidiaries will only make claims against the
      Special Escrow Fund based on any provisional or definitive Tax assessment
      by the applicable Spanish Tax authorities. NAI and its Subsidiaries
      further agrees not intentionally initiate or prompt such an investigation
      or assessment.

                  (vi)  Objections to Claims. At the time of delivery of any
      Officer's Certificate to the Escrow Agent, Escrow Agent or NAI shall
      promptly notify each of the Sellers via facsimile pursuant to Section 8(f)
      below and a duplicate copy of such certificate shall be delivered to each
      of the Sellers, and for a period of twenty (20) days after such delivery
      the Escrow Agent shall make no delivery to NAI or its Subsidiaries of any
      General or Special Escrow Amount(s) specified in such Officer's
      Certificate unless the Escrow Agent shall have received written
      authorization from each of the Sellers to make such delivery. After the
      expiration of such twenty (20) day period, the Escrow Agent shall make
      delivery of an amount from the applicable Escrow Fund in accordance with
      such Officer's Certificate and Section (c)(v) hereof, provided, that, no
      such payment or delivery may be made if both Sellers shall object in a
      written statement to the claim made in the Officer's Certificate, and such
      statement shall have been delivered to the Escrow Agent prior to the
      expiration of such twenty (20) day period. The Sellers will only submit an
      objection in good faith.

                  (vii) Resolution of Conflicts; Arbitration.

                        (A)   In case both Sellers shall so object in writing to
            any claim or claims made in any Officer's Certificate, the Sellers
            and NAI shall attempt, within sixty (60) days from such written
            objection, in good faith to agree upon the rights of the respective
            parties with respect to each of such claims. If the Sellers and NAI
            should so agree, a memorandum setting forth such agreement shall be
            prepared and signed by both parties and shall be furnished to the
            Escrow Agent. The Escrow Agent shall be entitled to rely on any such
            memorandum signed by NAI and the Sellers and distribute amounts from
            the Escrow Funds in accordance with the terms thereof.


                                      -30-
<PAGE>   36
                        (B)   If no such agreement can be reached after good
            faith negotiation, then after such sixty (60) day period either NAI
            or both Sellers may demand arbitration of the matter unless the
            amount of the damage or loss is at issue in pending litigation with
            a third party, in which event arbitration shall not be commenced
            until such amount is ascertained or both parties agree to
            arbitration; and in either such event the matter shall be settled by
            arbitration conducted by three arbitrators. NAI and both Sellers
            shall each select one arbitrator, and the two arbitrators so
            selected shall select a third arbitrator (who shall be affiliated
            with a Big Five accounting firm or any successor thereto (other than
            Price Waterhouse, Coopers & Lybrand or Arthur Andersen)). Failing
            agreement on the appointment of the third arbitrator, such third
            arbitrator shall be appointed by the American Arbitration
            Association. The arbitrators shall, within ten (10) business days
            after the last day of any hearings on any motion, issue a definitive
            ruling on such motion. The arbitrator shall also, within twenty (20)
            business days from the last day of any hearings regarding the
            issuance of any awards, issue a definitive ruling on the issuance of
            any such award in such arbitration. The arbitrators shall also
            establish procedures designed to reduce the cost and time for
            discovery while allowing the parties an opportunity, adequate in the
            sole judgement of the arbitrators, to discover relevant information
            from the opposing parties about the subject matter of the dispute.
            The arbitrators shall rule upon motions to compel or limit discovery
            and shall have the authority to impose sanctions, including
            attorneys fees and costs, to the extent as a court of competent law
            or equity, should the arbitrators determine that discovery was
            sought without substantial justification or that discovery was
            refused or objected to without substantial justification. The
            decision of a majority of the three arbitrators as to the validity
            and amount of any claim in such Officer's Certificate shall be
            binding and conclusive upon the parties to this Agreement, and
            notwithstanding anything in Article VII hereof, the Escrow Agent
            shall be entitled to act in accordance with such decision and make
            or withhold payments out of the Escrow Fund(s) in accordance
            therewith. Such decision shall be written and shall be supported by
            written findings of fact and conclusions which shall set forth the
            award, judgment, decree or order awarded by the arbitrators.

                        (C)   In no event may punitive or exemplary damages be
            awarded in any arbitration, and arbitration between the parities
            shall be final and binding. Judgment upon any award rendered by the
            arbitrators may be entered in any court having jurisdiction. Any
            such arbitration shall be held in Madrid, Spain. Each party to any
            arbitration pursuant to this Section 7(c)(vii) shall pay its own
            expenses; the fees of each arbitrator and any administrative fee of
            the sponsoring arbitration entity, if any, shall be borne equally by
            NAI, on the one hand, and the Sellers, on the other.

                  (viii) Third-Party Claims. In the event NAI or its
      Subsidiaries become aware of a third-party claim which NAI or its
      Subsidiaries believe may result in a demand against the Escrow Funds, NAI
      shall promptly notify each of the Sellers of such claim shall deliver to
      each of the Sellers a copy of such claim, complaint or demand, and the
      Sellers who have monies in 


                                      -31-
<PAGE>   37
      the escrow shall be entitled, at their expense, to participate in any
      defense of such claim. NAI shall consult with the Sellers prior to the
      settlement of any such claim and discuss with the Sellers in good faith
      any input regarding the claim and potential settlement the Sellers may
      have prior to any settlement. After such consultation, NAI shall have the
      right in its sole discretion to settle any such claim. The foregoing
      provisions with respect to the Sellers' participation at their expense
      shall in no event entitle the Sellers to initiate or conduct any
      negotiations with respect to any third party claims (including any claims
      with respect to Special Losses) without the physical presence and
      participation of NAI's representatives. Notwithstanding any provision to
      the contrary, in defending any Special Tax Matter, NAI agrees to retain,
      and maintain for so long as such counsel performs to NAI's reasonable
      satisfaction, Diaz-Arias as its Spanish tax counsel.


                  (ix)  Escrow Agent's Duties.

                        (A)   The Escrow Agent shall be obligated only for the
            performance of such duties as are specifically set forth herein, and
            as set forth in any additional written escrow instructions which the
            Escrow Agent may receive after the date of this Agreement which are
            signed by an officer of NAI and the Sellers, and may rely and shall
            be protected in relying or refraining from acting on any instrument
            reasonably believed to be genuine and to have been signed or
            presented by the proper party or parties. The Escrow Agent shall not
            be liable for any act done or omitted hereunder as Escrow Agent
            while acting in good faith and in the exercise of reasonable
            judgment, and any act done or omitted pursuant to the written advice
            of counsel shall be conclusive evidence of such good faith.

                        (B)   The Escrow Agent is hereby expressly authorized to
            disregard any and all warnings given by any of the parties hereto or
            by any other person, excepting only orders or process of courts of
            law, and is hereby expressly authorized to comply with and obey
            orders, judgments or decrees of any court. In case the Escrow Agent
            obeys or complies with any such order, judgment or decree of any
            court, the Escrow Agent shall not be liable to any of the parties
            hereto or to any other person by reason of such compliance,
            notwithstanding any such order, judgment or decree being
            subsequently reversed, modified, annulled, set aside, vacated or
            found to have been entered without jurisdiction.

                        (C)   The Escrow Agent shall not be liable in any
            respect on account of the identity, authority or rights of the
            parties executing or delivering or purporting to execute or deliver
            this Agreement or any documents or papers deposited or called for
            hereunder.

                        (D)   The Escrow Agent shall not be liable for the
            expiration of any rights under any statute of limitations with
            respect to this Agreement or any documents deposited with the Escrow
            Agent.

<PAGE>   38
                        (E)   The Escrow Agent may resign at any time upon
            giving at least thirty (30) days written notice to NAI and each of
            the Sellers; provided, however, that no such resignation shall
            become effective until the appointment of a successor escrow agent
            which shall be accomplished as follows: NAI and the Sellers shall
            use their best efforts to mutually agree upon a successor escrow
            agent within thirty (30) days after receiving such notice. If the
            parties fail to agree upon a successor escrow agent within such
            time, NAI shall have the right to appoint a successor escrow agent
            (which, in such case, shall be a financial institution with assets
            of at least $1 billion (USD)). The successor escrow agent selected
            in the preceding manner shall execute and deliver an instrument
            accepting such appointment and it shall thereupon be deemed the
            Escrow Agent hereunder and it shall without further acts be vested
            with all the estates, properties, rights, powers, and duties of the
            predecessor Escrow Agent as if originally named as Escrow Agent.
            Thereafter, the predecessor Escrow Agent shall be discharged for any
            further duties and liabilities under this Agreement.

                  (x)   Fees. All fees of the Escrow Agent for performance of
      its duties hereunder shall be paid by NAI. It is understood that the fees
      and usual charges agreed upon for services of the Escrow Agent shall be
      considered compensation for ordinary services as contemplated by the
      Agreement.

            (d)   Limitation on Liability. Notwithstanding any other provision
of this Agreement to the contrary, absent fraud or bad faith, the liability of
each Seller with respect to any claim for a breach of any representation,
warranty, covenant or agreement contained in this Agreement, the Collateral
Documents or the Sellers Disclosure Schedule shall be limited to the amount of
the sum of the General Escrow Fund and the Special Escrow Fund with all claims
being made, as applicable, first against such Seller's Proportionate Escrow
Interest in the General Escrow Fund and Special Escrow Fund.

            (e)   Valuation of Escrowed NAI Common Stock. In accordance with the
requirements of pooling of interests accounting, for the purposes of satisfying
claims made against the General Escrow Fund and the Special Escrow Fund, shares
of NAI Common Stock held in such escrow shall be valued at the Determined Price.

                                  ARTICLE VIII

      8.    Miscellaneous.

            (a)   Press Releases and Public Announcements. No Party shall issue
any press release or make any public announcement relating to the subject matter
of this Agreement prior to the Closing without the prior written approval of NAI
and the Sellers; provided, however, that any Party may make any public
disclosure it believes in good faith is required by applicable law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the disclosing Party will use its best efforts to advise the other Parties
prior to making the disclosure) or immediately thereafter if prior advise is not
possible.

construed in accordance with the domestic laws of Spain without giving effect to

jurisdiction) that would cause the application of the laws of any jurisdiction
other than Spain.

            (h)   Amendments and Waivers. No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by NAI
and each of the Sellers. No waiver by any Party of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

            (i)   Severability. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or

                  by way of deduction from any portion of the Purchase Price
                  that remains unpaid and to the extent any such damage, loss,
                  liability or expense cannot be satisfied out of such unpaid
                  part of the Purchase Price, the Sellers agree to reimburse the
                  Purchaser in cash promptly on request.

                  will take all such steps as may be necessary or appropriate to

                  permitted by applicable or ten per cent (10%) per annum, from

                                    RECITALS

into a Stock Purchase Agreement on the date hereof (the "PURCHASE AGREEMENT")

Agreement, as of the Closing Date, the shares of Company Common Stock that are
issued to the Shareholders pursuant to the Purchase Agreement shall be granted
registration rights as set forth herein; and

        WHEREAS, all terms not otherwise defined herein shall have the same
meanings ascribed to them in the Purchase Agreement;

        NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

        1. Registration Rights. The Company covenants and agrees as follows:

               1.1 Definitions. For purposes of this Section 1:

                      (a) The term "Act" means the Securities Act of 1933, as
amended.

                      (b) The term "1934 Act" shall mean the Securities Exchange
Act of 1934, as amended.

                      (c) The term "register," "registered," and "registration"

                      (d) The term "Registrable Securities" means the Common
Stock of the Company ("Common Stock") issued to the Shareholders in accordance
with the terms and conditions of the Purchase Agreement and any securities of
the Company issued as a dividend on or other distribution with respect to, or in
exchange for or replacement of, such common stock.


<PAGE>   2
                      (e) The term "SEC" shall mean the Securities and Exchange
Commission.

               1.2 Obligations of the Company. Whenever required under this
Section 1 to effect the registration of any Registrable Securities, the Company
shall, as soon as reasonably possible:

                      (a) Prepare and file with the SEC as soon as reasonably
possible, but in no event later than 180 days after the Closing Date, a
registration statement on Form S-3, or other available form of registration
statement with respect to such Registrable Securities (hereinafter referred to
as the "Registration Statement") and use its reasonable best efforts to cause
such registration statement to become effective as soon as reasonably possible
thereafter, and, subject to the provisions below, use its reasonable best
efforts to, keep such registration statement effective for a period of 180 days
or, if earlier, until the Shareholders have sold all of the Registrable
Securities. If at any time after a registration statement becomes effective, the
Company advises the Shareholders in writing that due to the existence of
material information that has not been disclosed to the public and included in
the registration statement it is necessary to amend the registration statement,
the Shareholders shall suspend any further sale of Registrable Securities
pursuant to the Registration Statement until the Company advises the
Shareholders that the registration statement has been amended. In such event,
the Company shall cause the registration statement to be amended forthwith,

statement during any time when the Company's officers and director are
prohibited from buying or selling the Company's Common Stock pursuant to the
Company's insider trading policy. Notwithstanding the foregoing sentence, the
Company shall file any amendment necessary for the Shareholders to recommence
sales under the registration statement concurrently with the commencement of any
period in which directors and officers of the Company are allowed to buy or sell
Common Stock pursuant to the Company's insider trading policy. In addition, the
Company may suspend use of the registration statement to the extent the Company
is advised by its legal counsel, such action is reasonably necessary to comply
with federal securities law. In the event the sales of Registrable Securities of
the Shareholders are suspended as provided above, the 180-day period during
which a registration statement must be kept effective shall be extended for the
total number of days during which sales are suspended.

                      (b) Subject to subsection 1.2(a), prepare and file with
the SEC such amendments and supplements to such Registration Statement and the
prospectus used in connection with such Registration Statement as may be
necessary to comply with the provisions of the Act with respect to the
disposition of all securities covered by such Registration Statement.

                      (c) Furnish to the Shareholders such numbers of copies of
a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as the Shareholders may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                      (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other (U.S.)
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Shareholders, provided that the Company shall not be required
in


                                       -2-

connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such
jurisdiction and except as may be required by the Act.

                      (e) The Company may include securities issued in
connection with any acquisition not otherwise registered on an S-4 Registration
Statement in the registration pursuant to this Agreement.

               1.3 Information from Shareholders. It shall be a condition
precedent to the obligations of the Company to take any action pursuant to this
Section 1 with respect to the Registrable Securities of the Shareholders that
the Shareholders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them, and the intended method of
disposition of such securities, as shall be required to effect the registration
of the Registrable Securities.

               1.4 Expenses of Registration. All expenses of the Shareholders,
including (without limitation) all registration, filing and qualification fees,
printers' and accounting fees, fees and disbursements of counsel for the Company
shall be borne by the Company; provided, however, that the Company shall not be
required to pay any professional fees of the Shareholders other than the fees of
one counsel to both Shareholders (not to exceed $2,000).

               1.5 Indemnification. In the event any Registrable Securities are
included in the Registration Statement under this Section 1:

                      (a) The Company will indemnify and hold harmless the
Shareholders, each of their directors, officers, trustees or beneficiaries, if
applicable and each person, if any, who controls a non-individual shareholder
within the meaning of the Act against any losses, claims, damages, or
liabilities (joint or several) to which the Shareholders may become subject
under the Act, or the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement,
including any preliminary prospectus or final prospectus con tained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements' therein not mis leading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, or any rule or regulation
promulgated under the Act, or the 1934 Act; and the Company will pay to the
Shareholders as incurred any legal or other expenses reasonably incurred by the
Shareholders in connection with investigating or defending any such loss, claim,
damage, liability, or action; provided, however, that the indemnity agreement
contained in this subsection 1.5(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company, which consent shall
not be unreasonably withheld, nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with information furnished in writing expressly for use in connection
with such registration by the Shareholders seeking


                                       -3-


<PAGE>   4
indemnification hereunder. In addition, the Company shall not be liable for any
untrue statement or omission in any prospectus if a supplement or amendment
thereto correcting such untrue statement or omission was delivered to the
Shareholders prior to the pertinent sale or sales by the Shareholders.

                      (b) Each Shareholder will indemnify and hold harmless the
Company, each of its directors, each of its officers who has signed the
Registration Statement, each person, if any, who controls the Company within the
meaning of the Act, any other shareholder selling securities in such
Registration Statement and any controlling person of any such shareholder,
against any losses, claims, damages, or liabilities (joint or several) to which
any of the foregoing persons may become subject, under the Act, or the 1934 Act
or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Shareholder expressly for use in connection with such
registration; and such Shareholder will pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection 1.5(b), in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 1.5(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of such Shareholder, which
consent shall not be unreasonably withheld; provided, that, in no event shall
any indemnity under this subsection 1.5(b) by such Shareholder exceed the gross
proceeds from the offering received by such Shareholder.

                      (c) Promptly after receipt by an indemnified party under
this Section 1.5 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.5, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if represen
tation of such indemnified party by the counsel retained by the indemnifying
party would be inappropri ate due to actual or potential differing interests
between such indemnified party and any other party represented by such counsel
in such proceeding. The failure to deliver written notice to the indemnifying
party within a reasonable time of the commencement of any such action, if
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.5, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.5.

                      (d) If the indemnification provided for in this Section
1.5 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such


                                       -4-


<PAGE>   5
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                      (e) The obligations of the Company, and the Shareholders
under this Section 1.5 shall survive the completion of any offering of
Registrable Securities in a registration statement under this Section 1, and
otherwise.

               1.6 Reports Under the Securities Exchange Act. The Company agrees
to file with the SEC in a timely manner all reports and other documents and
information required of the Company under the 1934 Act, and take such other
actions as may be necessary to assure the availability of Form S-3 for use in
connection with the registration rights provided in this Agreement.

               1.7 Rules 144 and 144A. The Company shall use commercially
reasonable efforts to file the reports required to be filed by it under the Act
and the 1934 Act in a timely manner and, if at any time the Company is not
required to file such reports, it will, upon the written request of both
Shareholders, make publicly available other information so long as necessary to
permit sales of the Shareholders' securities pursuant to Rule 144 and 144A. The
Company covenants that it will take such further action as the Shareholders may
reasonably request, all to the extent required from time to time to enable the
Shareholders to sell securities without registration under the Act within the
limitation of the exemptions provided by Rules 144 and 144A (including the
requirements of Rule 144A(d)(4)).

        2. Miscellaneous.

               2.1 Notices. All notices and other communications hereunder shall
be in writing and shall be deemed given if delivered personally or by commercial
delivery service, or mailed by registered or certified mail (return receipt
requested) or sent via facsimile (with acknowledgment of complete trans mission)

more counterparts have been signed by each of the parties and delivered to the

               2.4 Entire Agreement; Assignment. This Agreement and the

                          REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION RIGHTS AGREEMENT is made as of May 28, 1998, by and
between Networks Associates, Inc., a Delaware corporation with registered office

Cernusco S/N (Milan), Italy, Mr. Giovanni Fracasso, Mr. Massimo Santini and Mr.

                                    RECITALS

         WHEREAS, concurrent with delivery of this Agreement, NA Combination,
Inc. (a wholly owned subsidiary of the Company) and the Shareholders are
entering into a Share Purchase Agreement (the "PURCHASE AGREEMENT") which
provides for the purchase (the "PURCHASE") of all of the issued and outstanding
shares of CSB Consulenza Software di Base Srl by the Company in exchange for
shares of Company Common Stock;

         WHEREAS, as an inducement to the Shareholders to enter into the
Purchase Agreement, as of the Closing Date, the holders of the shares of Company
Common Stock that are issued to the Shareholders pursuant to the Purchase
Agreement shall be granted registration rights as set forth herein; and

         WHEREAS, all terms not otherwise defined herein shall have the same
meanings ascribed to them in the Purchase Agreement;

         NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

1        Registration Rights. The Company covenants and agrees as follows:

1.1      Definitions. For purposes of this Section 1:

         (a)      The term "Act" means the Securities Act of 1933, as amended,
                  enacted by the United States of America.

         (b)      The term "1934 Act" shall mean the Securities Exchange Act of
                  1934, as amended, enacted by the United States of America.

         (c)      The term "register," "registered," and "registration" refer to
                  a registration effected by preparing and filing a registration
                  statement or similar document in compliance with the Act, and
                  the declaration or ordering of effectiveness of such
                  registration statement or document.


                                       1

<PAGE>   2

         (d)      The term "Registrable Securities" means the Common Stock of
                  the Company ("Common Stock") issued to the Shareholders in
                  accordance with the terms and conditions of the Purchase
                  Agreement and any securities of the Company issued as a
                  dividend on or other distribution with respect to, or in
                  exchange for or replacement of, such common stock.

         (e)      The term "SEC" shall mean the Securities and Exchange
                  Commission.

1.2      Obligations of the Company. Whenever required under this Section 1 to
         effect the registration of any Registrable Securities, the Company
         shall, as soon as reasonably possible:

         (a)      Prepare and file with the SEC as soon as reasonably possible,
                  but in no event later than 180 days after the Closing Date, a
                  registration statement on Form S-3, or other available form of
                  registration statement with respect to such Registrable
                  Securities (hereinafter referred to as the "Registration
                  Statement") and use its reasonable best efforts to cause such
                  registration statement to become effective as soon as
                  reasonably possible thereafter, and, subject to the provisions
                  below, use its reasonable best efforts to, keep such
                  registration statement effective for a period of 180 days or,
                  if earlier, until the Shareholders have sold all of the
                  Registrable Securities. If at any time after a registration
                  statement becomes effective, the Company advises the
                  Shareholders' Agent (defined below) in writing that due to the
                  existence of material information that has not been disclosed
                  to the public and included in the registration statement it is
                  necessary to amend the registration statement, the
                  Shareholders shall suspend any further sale of Registrable
                  Securities pursuant to the Registration Statement until the
                  Company advises the Shareholders' Agent that the registration
                  statement has been amended. In such event, the Company shall
                  cause the registration statement to be amended forthwith,
                  provided that the Company shall not be required to amend the
                  registration statement during any time when the Company's
                  officers and director are prohibited from buying or selling
                  the Company's Common Stock pursuant to the Company's insider
                  trading policy. Notwithstanding the foregoing sentence, the
                  Company shall file any amendment necessary for the
                  Shareholders to recommence sales under the registration
                  statement concurrently with the commencement of any period in
                  which directors and officers of the Company are allowed to buy
                  or sell Common Stock pursuant to the Company's insider trading
                  policy. In addition, the Company may suspend use of the
                  registration statement to the extent the Company is advised by
                  its legal counsel, such action is reasonably necessary to
                  comply with federal securities law. In the event the sales of
                  Registrable Securities of the Shareholders are suspended as
                  provided above, the 180-day period during which a registration
                  statement 


                                       2
<PAGE>   3

                  must be kept effective shall be extended for the total number
                  of days during which sales are suspended.

         (b)      Subject to subsection 1.2 (a), prepare and file with the SEC
                  such amendments and supplements to such Registration Statement
                  and the prospectus used in connection with such Registration
                  Statement as may be necessary to comply with the provisions of
                  the Act with respect to the disposition of all securities
                  covered by such Registration Statement.

         (c)      Furnish to the "Shareholders' Agent" to be designated by
                  Shareholders such numbers of copies of a prospectus, including
                  a preliminary prospectus, in conformity with the requirements
                  of the Act, and such other documents as the Shareholders may
                  reasonably request in order to facilitate the disposition of
                  Registrable Securities owned by them.

         (d)      Use its best efforts to register and qualify the securities
                  covered by such registration statement under such other (U.S.)
                  securities or Blue Sky laws of such jurisdictions as shall be
                  reasonably requested by the Shareholders, provided that the
                  Company shall not be required in connection therewith or as a
                  condition thereto to qualify to do business or to file a
                  general consent to service of process in any such states or
                  jurisdictions, unless the Company is already subject to
                  service in such jurisdiction and except as may be required by
                  the Act.

         (e)      The Company may include securities issued in connection with
                  any acquisition not otherwise registered on an S-4
                  Registration Statement in the registration pursuant to this
                  Agreement.

1.3      Information from Shareholders. It shall be a condition precedent to the
         obligations of the Company to take any action pursuant to this Section
         1 with respect to the Registrable Securities of the Shareholders that
         the Shareholders shall furnish to the Company such information
         regarding themselves, the Registrable Securities held by them, and the
         intended method of disposition of such securities, as shall be required
         to effect the registration of the Registrable Securities.

1.4      Expenses of Registration. All expenses of the Shareholders, including
         (without limitation) all registration, filing and qualification fees,
         printers' and accounting fees, fees and disbursements of counsel for
         the Company shall be borne by the Company; provided, however, that the
         Company shall not be required to pay any professional fees of the
         Shareholders.

1.5      Indemnification. In the event any Registrable Securities are included
         in the Registration Statement under this Section 1:

         (a)      The Company will indemnify and hold harmless the Shareholders,
                  each of their directors, officers, trustees or beneficiaries,
                  if applicable and each person, if any, who controls a
                  non-individual shareholder within the meaning of the Act
                  against any losses, claims, damages, or liabilities (joint or
                  several) to which the Shareholders may become subject under
                  the Act, or the 1934 Act or other federal or state law,
                  insofar as such losses, claims, damages, or liabilities (or
                  actions in respect thereof) arise out of or are based upon any
                  of the following statements, omissions or violations
                  (collectively a "Violation"): (i) any untrue statement or
                  alleged untrue statement of a material fact contained in the
                  Registration Statement, including any preliminary prospectus
                  or final prospectus contained therein or any amendments or
                  supplements thereto, (ii) the omission or alleged omission to
                  state therein a material fact required to be stated therein,
                  or necessary to make the statements' therein not misleading,
                  or (iii) any violation or alleged violation by the Company of
                  the Act, the 1934 Act, or any rule or regulation promulgated
                  under the Act, or the 1934 Act; and the Company will pay to
                  the Shareholders as incurred any legal or other expenses
                  reasonably incurred by the Shareholders in connection with
                  investigating or defending any such loss, claim, damage,
                  liability, or action; provided, however, that the indemnity
                  agreement contained in this subsection 1.5 (a) shall not apply
                  to amounts paid in settlement of any such loss, claim, damage,
                  liability, or action if such settlement is effected without
                  the consent of the Company, which consent shall not be
                  unreasonably withheld, nor shall the Company be liable in any
                  such case for any such loss, claim, damage, liability, or
                  action to the extent that it arises out of or is based upon a
                  Violation which occurs in reliance upon and in conformity with
                  information furnished in writing expressly for use in
                  connection with such registration by the Shareholders seeking
                  indemnification hereunder. In addition, the Company shall not
                  be liable for any untrue statement or omission in any
                  prospectus if a supplement or amendment thereto correcting
                  such untrue statement or omission was delivered to the
                  Shareholders' Agent prior to the pertinent sale or sales by
                  the Shareholders.

         (b)      Each Shareholder will indemnify and hold harmless the Company,
                  each of its directors, each of its officers who has signed the
                  Registration Statement, each person, if any, who controls the
                  Company within the meaning of the Act, any other shareholder
                  selling securities in such Registration Statement and any
                  controlling person of any such shareholder, against any
                  losses, claims, damages, or liabilities (joint or several) to
                  which any of the foregoing persons may become subject, under
                  the Act, or the 1934 Act or other federal or state law,
                  insofar as such losses, claims, damages, or liabilities (or
                  actions in respect thereto) arise out of or are based upon any
                  Violation, in each case to the extent (and only to the extent)
                  that such Violation occurs in reliance upon and in 

                                       4


<PAGE>   5

                  conformity with written information furnished by such
                  Shareholder expressly for use in connection with such
                  registration; and such Shareholder will pay, as incurred, any
                  legal or other expenses reasonably incurred by any person
                  intended to be indemnified pursuant to this subsection 1.5
                  (b), in connection with investigating or defending any such
                  loss, claim, damage, liability, or action; provided, however,
                  that the indemnity agreement contained in this subsection 1.5
                  (b) shall not apply to amounts paid in settlement of any such
                  loss, claim, damage, liability or action if such settlement is
                  effected without the consent of such Shareholder, which
                  consent shall not be unreasonably withheld.

         (c)      Promptly after receipt by an indemnified party under this
                  Section 1.5 of notice of the commencement of any action
                  (including any governmental action), such indemnified party
                  will, if a claim in respect thereof is to be made against any
                  indemnifying party under this Section 1.5, deliver to the
                  indemnifying party a written notice of the commencement
                  thereof and the indemnifying party shall have the right to
                  participate in, and, to the extent the indemnifying party so
                  desires, jointly with any other indemnifying party similarly
                  noticed, to assume the defense thereof with counsel mutually
                  satisfactory to the parties; provided, however, that an
                  indemnified party (together with all other indemnified parties
                  which may be represented without conflict by one counsel)
                  shall have the right to retain one separate counsel, with the
                  fees and expenses to be paid by the indemnifying party, if
                  representation of such indemnified party by the counsel
                  retained by the indemnifying party would be inappropriate due
                  to actual or potential differing interests between such
                  indemnified party and any other party represented by such
                  counsel in such proceeding. The failure to deliver written
                  notice to the indemnifying party within a reasonable time of
                  the commencement of any such action, if prejudicial to its
                  ability to defend such action, shall relieve such indemnifying
                  party of any liability to the indemnified party under this
                  Section 1.5, but the omission so to deliver written notice to
                  the indemnifying party will not relieve it of any liability
                  that it may have to any indemnified party otherwise than under
                  this Section 1.5.

         (d)      If the indemnification provided for in this Section 1.5 is
                  held by a court of competent jurisdiction to be unavailable to
                  an indemnified party with respect to any loss, liability,
                  claim, damage, or expense referred to therein, then the
                  indemnifying party, in lieu of indemnifying such indemnified
                  party hereunder, shall contribute to the amount paid or
                  payable by such indemnified party as a result of such loss,
                  liability, claim, damage, or expense in such proportion as is
                  appropriate to reflect the relative fault of the indemnifying
                  party on the one hand and of the indemnified party on the
                  other in connection with the statements or omissions that
                  resulted in such loss, liability, claim, damage, or expense 

                                       5
<PAGE>   6

                  as well as any other relevant equitable considerations. The
                  relative fault of the indemnifying party and of the
                  indemnified party shall be determined by reference to, among
                  other things, whether the untrue or alleged untrue statement
                  of a material fact or the omission to state a material fact
                  relates to information supplied by the indemnifying party or
                  by the indemnified party and the parties' relative intent,
                  knowledge, access to information, and opportunity to correct
                  or prevent such statement or omission.

         (e)      The obligations of the Company, and the Shareholders under
                  this Section 1.5 shall survive the completion of any offering
                  of Registrable Securities in a registration statement under
                  this Section 1, and otherwise.

1.6      Reports Under the Securities Exchange Act. The Company agrees to file
         with the SEC in a timely manner all reports and other documents and
         information required of the Company under the 1934 Act, and take such
         other actions as may be necessary to assure the availability of Form
         S-3 for use in connection with the registration rights provided in this
         Agreement.

1.7      Rules 144 and 144A. The Company shall use commercially reasonable
         efforts to file the reports required to be filed by it under the Act
         and the 1934 Act in a timely manner and, if at any time the Company is
         not required to file such reports, it will, upon the written request of
         the Shareholders' Agent, make publicly available other information so
         long as necessary to permit sales of the Shareholders' securities
         pursuant to Rule 144 and 144A. The Company covenants that it will take
         such further action as the Shareholders may reasonably request, all to
         the extent required from time to time to enable the Shareholders to
         sell securities without registration under the Act within the
         limitation of the exemptions provided by Rules 144 and 144A
         (including the requirements of Rule 144A(d)(4)).

2.       Miscellaneous.

2.1      Notices. Notice to the Shareholders' Agent shall constitute notice to
         all the shareholders party hereto. All notices and other communications
         hereunder shall be in writing and shall be deemed given if delivered
         personally or by commercial delivery service, or mailed by registered

         (with acknowledgment of complete transmission) to the parties at the
         following addresses (or at such other address for a party as shall be

                  shareholders

2.2      Interpretation. The words "include," "includes" and "including" when
         used herein shall be deemed in each case to be followed by the words
         "without limitation." The table of contents and headings contained in
         this Agreement are for reference purposes only and shall not affect in
         any way the meaning or interpretation of this Agreement.

2.3      Counterparts. This Agreement may be executed in one or more
         counterparts, all of which shall be considered one and the same
         agreement and shall become effective when one or more counterparts have
         been signed by each of the parties and delivered to the other party, it
         being understood that all parties need not sign the same counterpart.

2.4      Entire Agreement Assignment. This Agreement and the documents and
         instruments and other agreements among the parties hereto referenced
         herein: (a) constitute the entire agreement among the parties with

         upon any other person (including, without limitation, those persons
         listed on any exhibits hereto) any rights or remedies hereunder; and
         (c) without the prior written consent of each party shall not be
         assigned by operation of law or otherwise, except that the Company may
         assign its rights and obligations hereunder to an affiliate of the
         Company provided that the Company shall remain liable for all its
         obligations hereunder notwithstanding such assignment. Any assignment
         of rights or delegation of duties under this Agreement by a party
         without the prior written consent of the other parties, if such consent
         is required hereby, shall be void.

2.5      Severability. In the event that any provision of this Agreement or the
         application thereof, becomes or is declared by a court of competent
         jurisdiction to be illegal, void or unenforceable, the remainder of
         this Agreement will continue in full force and effect and the
         application of such provision to other persons or circumstances will be
         interpreted so as reasonably to effect the intent of the parties
         hereto. The parties further agree to replace such void or unenforceable
         provision of this Agreement with a valid and enforceable provision that
         will achieve, to the extent possible, the economic, business and other
         purposes of such void or unenforceable provision.

2.6      Other Remedies. Except as otherwise provided herein, any and all
         remedies herein expressly conferred upon a party will be deemed
         cumulative with and not exclusive of any other remedy conferred hereby,
         or by law or equity upon such party, and the exercise by a party of any
         one remedy will not preclude the exercise of any other remedy.

2.7      Governing Law. This Agreement shall be governed by and construed in
         accordance with the laws of the State of Delaware, regardless of the
         laws that might otherwise govern under applicable principles of
         conflicts of laws thereof.

     RE:  REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-3 filed by you with
the Securities and Exchange Commission on or about August 6, 1998 (the
"Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of a total of 238,019 shares of your Common
Stock (the "Shares"). We understand that the Shares are to be sold from time to
time on the NASDAQ National Market at prevailing prices or as otherwise
described in the Registration Statement. As legal counsel for Networks
Associates, Inc., we have examined the proceedings taken by you in connection
with the sale of the Shares.

     It is our opinion that the Shares are legally and validly issued, fully
paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement and any amendments to it.

                                            Very truly yours,

                                            WILSON SONSINI GOODRICH & ROSATI
