Item 5.    Other Events

           On June 9, 1998, Networks Associates, Inc., a Delaware corporation
("Network Associates"), 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 (the "Acquisition") by means of a Scheme of Arrangement in
accordance with Section 425 of the Companies Act (as amended) of England and
Wales. Pursuant to the terms of the Transaction Agreement, dated June 9, 1998,
by and between Dr. Solomon and Network Associates (the "Transaction Agreement"),
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
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.

           The Acquisition is expected to close within 90 days contingent upon
the fulfilment of certain conditions as outlined in the Transaction Agreement
including, but not limited to, expiration or early termination of the waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and approval of the Acquisition by both the shareholders of Dr. Solomon
and the High Court of Justice in England and Wales. The Acquisition will be
accounted for as a pooling of interests.

June 9, 1998

                   NETWORK ASSOCIATES TO ACQUIRE DR SOLOMON'S

     European Anti-Virus Software Vendor to Join Preeminent Network Security
                             and Management Company

Network Associates (NASDAQ: NETA), formed late last year by the merger of McAfee
Associates and Network General, and Dr Solomon's Group PLC (NASDAQ: SOLLY),
today announced that they have signed a definitive agreement whereby Network
Associates proposes to acquire Dr Solomon's, a leading European-based provider
of anti-virus software products. The Acquisition, valued at over $640 million,
will be a taxable transaction to US holders of Dr Solomon's Ordinary Shares and
ADSs and is expected to be accounted for as a pooling of interests for US
accounting purposes.

Today's announcement builds on the foundation of Network Associates' core
strengths and extends its popular anti-virus technology, which evolved from its
flagship product, McAfee VirusScan. Shortly after the Acquisition, Dr Solomon's
Anti-Virus Toolkit will be available as part of Network Associates' enterprise
security suites, the Total Virus Defense (TVD) suite, and Net Tools Secure, the
only integrated software bundle on the market to incorporate anti-virus,
encryption, authentication, firewall, intrusion detection and scanning
technology.

"With today's news, Network Associates further demonstrates its vision and
commitment to deliver world-class enterprise security products to the global
market," said Bill Larson, CEO, chairman and president of Network Associates.
"Network Associates is primed to deploy integrated enterprise security systems
to Europe's largest companies."

"I believe that Dr Solomon's and Network Associates represent an excellent fit
in terms of products, markets and infrastructure," said Geoff Leary, chief
executive of Dr Solomon's. "The combination should enable one of the most
comprehensive ranges of security products to be made available to Dr Solomon's
customers around the world."

Network Associates has distributed more than 50 million units of its security
and anti-virus software, and its customer base includes a significant number of
Fortune 500 companies. Its PGP encryption and authentication technology is
considered a worldwide standard for Internet email and file encryption. Network
Associates' market presence will be enhanced through access to Dr Solomon's
customers.

Network Associates was one of the first anti-virus providers on the market to
attack virus infection through a multi-tiered approach with the TVD suite. In
1998 Network Associates evolved and expanded that strategy with the delivery of
its Net Tools Secure suite, which addresses network security through an
integrated, multi-tiered security architecture.

Network Associates expects that it will incur a one time charge in the third
quarter of 1998 resulting from expenses and other charges associated with the
Acquisition. Excluding this one time charge, the Board of Network Associates
expects the Acquisition to be modestly dilutive to earnings per share in the
third quarter of its financial year ending December 31, 1998, but is expected to
be non-dilutive in the fourth quarter, and to be modestly accretive for the
financial year ending December 31, 1999. This statement should not be
interpreted to mean that the future earnings per share of Network Associates
Common Stock will necessarily be greater than the earnings per share of Network
Associates for its financial year ending December 31, 1997.

The proposed Acquisition is to take place by means of a scheme of arrangement
under section 425 of the UK Companies Act of 1985. Under the terms of the
Acquisition, holders of Dr Solomon's Ordinary Shares will receive 0.27625 shares
of Network Associates' Common Stock for each Dr Solomon's Ordinary

<PAGE>   2



Share. As one Dr Solomon's ADS represents three Dr Solomon's Ordinary Shares,
this is equivalent to 0.82875 shares of Network Associates Common Stock for each
Dr Solomon's ADS. The Boards of Dr Solomon's and Network Associates expect the
Acquisition to be completed within approximately 90 days, subject to the
approval of Dr Solomon's shareholders and the High Court in London, regulatory
reviews and the satisfaction or waiver of other conditions.

With headquarters in Aylesbury, UK, Dr Solomon's Group PLC, a leading supplier
of anti-virus software, develops, markets and supports anti-virus software
programs for PCs and PC networks. Dr Solomon's products provide effective and
easy-to-use software solutions to the risks posed by the proliferation of new
and increasingly sophisticated types of computer viruses. The most recent
version of the Dr Solomon's Anti-Virus Toolkit can detect and identify more than
19,000 known computer viruses.

With headquarters in Santa Clara, California, Network Associates, Inc., formed
by the merger of McAfee Associates and Network General, is a leading supplier of
enterprise network security and management solutions. Network Associates' Net
Tools Secure and Net Tools Manager offer suite-based network security and
management solutions. Net Tools Secure and Net Tools Manager suites combine to
create Net Tools which centralizes these solutions within an easy-to-use,
integrated systems management environment. For more information, Network
Associates can be reached at (408) 988-3832 or on the Internet at http://www.

         ACQUISITION OF DR SOLOMON'S GROUP PLC BY NETWORK ASSOCIATES INC

Introduction

The Boards of Dr Solomon's and Network Associates announce that they have agreed
the terms for the proposed Acquisition of the entire issued share capital of Dr
Solomon's by Network Associates by means of a scheme of arrangement under
section 425 of the Companies Act.

Both Boards expect the Acquisition to be completed within approximately 90 days,
subject to Dr Solomon's shareholder and Court approval, regulatory reviews and
the satisfaction or waiver of other conditions set out in Appendix I to this
announcement.

Terms of the Acquisition

Under the terms of the Acquisition, holders of Dr Solomon's Ordinary Shares will
receive 0.27625 shares of Network Associates' Common Stock for each Dr Solomon's
Ordinary Share. As one Dr Solomon's ADS represents three Dr Solomon's Ordinary
Shares, this is equivalent to 0.82875 shares of Network Associates' Common Stock
for each Dr Solomon's ADS.

The Acquisition values the entire current issued share capital of Dr Solomon's
at approximately $642 million (pound sterling 393 million) and each Dr Solomon's
ADS at $34.81, based on the last sale price of $42.00 per share of Network
Associates' Common Stock on NASDAQ on June 8, 1998 (the latest dealing day prior
to the announcement of the Acquisition). This represents a premium of 15.5 per
cent over the average last sale price of $30.15 of a Dr Solomon's ADS on NASDAQ
for the 30 days prior to the date of this announcement and a premium of 8.4 per
cent over the last sale price of $32.125 of a Dr Solomon's ADS on NASDAQ on June
8, 1998. The Acquisition will be a taxable transaction to US holders of Dr
Solomon's Ordinary Shares and Dr Solomon's ADSs. The Acquisition is expected to
be accounted for as a pooling of interests for US accounting purposes.

Following the completion of the Acquisition, it is expected that former holders
of Dr Solomon's Ordinary Shares and Dr Solomon's ADSs will hold approximately
11.7% of the enlarged Common Stock of Network Associates (excluding the effect
of the exercise of any options).

Network Associates currently holds 100 Dr Solomon's ADSs and intends to make
further purchases (subject to applicable securities laws) of a small number of
Dr Solomon's Ordinary Shares and/or Dr Solomon's ADSs (representing no more than
600 underlying shares) prior to the Effective Date. Network Associates intends
that immediately following the Effective Date, Network Associates will transfer
all or a portion of the Dr Solomon's Ordinary Shares owned by it to a direct or
indirect subsidiary.

Fractions of new Network Associates' Common Stock will not be issued. In lieu
thereof, holders of Dr Solomon's Ordinary Shares and/or Dr Solomon's ADSs will
receive cash (without interest) in an amount equal to the product of such
fractional part of Network Associates Common Stock multiplied by the closing
market price of Network Associates Common Stock on NASDAQ on the day following
the Effective Date. (Amounts of less than pound sterling 3.00 (or the US dollar
equivalent) will be retained for the benefit of Network Associates). The
Acquisition is subject to a number of terms and conditions which, together with
the obligations of Network Associates and Dr Solomon's to implement the Scheme,
are governed by the Transaction Agreement dated June 9, 1998. The conditions are
set out in Appendix I to this announcement.

Recommendation

The directors of Dr Solomon's, who have been so advised by Goldman Sachs

<PAGE>   5


International, financial adviser to Dr Solomon's, consider the terms of the
Acquisition to be fair and reasonable. In providing advice to the directors of
Dr Solomon's, Goldman Sachs International has taken into account the directors'
commercial assessments.

The directors of Dr Solomon's are unanimously recommending holders of Dr
Solomon's Ordinary Shares and Dr Solomon's ADSs to approve the Scheme and
Acquisition, as they intend to do in respect of their own beneficial holdings
totalling 10,125,000 Dr Solomon's Ordinary Shares, representing 18.3% of Dr
Solomon's issued share capital.

Information on Dr Solomon's

Dr Solomon's, a leading supplier of anti-virus software in the UK and elsewhere
in Europe, develops, markets and supports anti-virus software programs for PCs

increasingly sophisticated types of computer viruses. Dr Solomon's principal
product line is the "Dr Solomon's Anti-Virus Toolkit" family of anti-virus
software programs. Since its introduction in 1989, the Toolkit has become one of

detection engine technology and feature-rich anti-virus management technology.

sterling 25.4 million). For the last four reported quarters, ended February 28,

Information on Network Associates

With headquarters in Santa Clara, California, Network Associates, formed late
last year by the merger of McAfee Associates and Network General, is a leading
supplier of enterprise network security and management solutions. Network
Associates focuses on providing broad and integrated network security and
management software products for enterprise customers, targeting in particular

significant number of Fortune 500 companies. Its PGP encryption and

network security products under the Net Tools Secure product suite including the
Total Virus Defense suite of anti-virus products, featuring a multi-tiered

on the market to attack virus infection through a multi-tiered approach with the
Total Virus Defense (TVD) suite. Network Associates Net Tools Manager product
suite includes the Total Network Visibility suite of network fault and
performance solutions and the Total Service Desk suite of integrated service

Many of Network Associates' network security and management products are

<PAGE>   6


available on a stand-alone basis. Network Associates is also a leader in
electronic software distribution, which is the principal means by which it
markets and distributes its software products to its customers.

For the year ended December 31, 1997, Network Associates recorded operating
profit of $194.0 million (1996: $136.5 million) (pre-acquisition and related
costs) and net income of $147.5 million (1996: $94.8 million) (pre-acquisition
and related costs), based on revenues of $612.2 million (1996: $407.6 million).
For the year ended December 31, 1997, revenue growth for 1997 was 50%. As of
March 31, 1998, Network Associates had $627 million in cash and $77 million in
deferred revenue.

On May 29, 1998, Network Associates effected a 3-for-2 stock split by means of a
stock dividend paid to stockholders of record on May 12, 1998.

Network Associates' Common Stock is quoted on NASDAQ. Network Associates had a
market capitalisation of approximately $4.9 billion as of June 8, 1998, based on
a last sale price of $42.00 per share of Network Associates' Common Stock on
that date.

In April 1998 Network Associates acquired Magic Solutions International, Inc, a
privately held provider of internal help desk and asset management solutions,
and Trusted Information Systems, Inc, a publicly held provider of comprehensive
security systems for computer networks for approximately $110 million and $300
million, respectively.

Background to and reasons for the Acquisition

The Boards of Dr Solomon's and Network Associates believe that Dr Solomon's and
Network Associates represent an excellent fit in terms of technology, products,
markets and infrastructure. The combined group will be one of the world's
largest companies catering primarily to the network security and management
markets, and offering a broad suite of products to protect, manage and monitor
corporate networks for enterprise customers seeking the benefits of a secure,
reliable computing network.

Today's announcement builds on the foundation of Network Associates' core
strengths and extends its popular anti-virus technology, which evolved from its
flagship product, McAfee VirusScan, an industry leader. Network Associates' core
strengths include its broad product line, its position in the rapidly growing
security market, its scale, its high quality services organisation with more
than 85 seasoned security consultants, its installed base with over 50 million
units distributed and its award-winning global virus research team with
laboratories on 5 continents. Shortly after the Acquisition, Dr Solomon's
Anti-Virus Toolkit will be available as part of Network Associates' enterprise
security suites, the Total Virus Defense (TVD) suite, and Net Tools Secure, the
only integrated software bundle on the market to incorporate anti-virus,
encryption, authentication, firewall, intrusion detection and scanning
technology.

Dr Solomon's strategy for the past two years has been based on three principal
themes: the maintenance of its leadership in anti-virus technology; the defense
and enhancement of its market leadership in the UK and Northern Europe; and
achieving sustainable and profitable market shares.

The combination will provide Network Associates with the potential to access Dr
Solomon's strong European distribution channels, benefit from Dr Solomon's
strategic product technologies, strengthen Network Associates' suite of
integrated security products, and achieve significant distribution channel and
services synergies.

Dr Solomon's should benefit from being part of a larger group with a broader
product range and greater overall market strength. Combining Network Associates'
successful marketing, sales, distribution and customer service expertise with Dr
Solomon's infrastructure, leading anti-virus technology, strong European
distribution channels and loyal customer base, should provide for greater
success for the combined Network Associates group than is likely to be achieved
separately by either Dr Solomon's or Network Associates. Given the expected
synergies and increased market opportunities created by the Acquisition, the
Boards of Network Associates and Dr Solomon's believe the Acquisition will be
beneficial to their respective shareholders and customers.
<PAGE>   7

The Board of Network Associates expects that it will incur a one time charge in
the third quarter of 1998, resulting from expenses and other charges associated
with the Acquisition. Excluding this one time charge, the Board of Network
Associates expects the Acquisition to be modestly dilutive to earnings per share
in the third quarter of its financial year ending December 31, 1998, but is
expected to be non-dilutive to earnings per share in the fourth quarter of its
financial year ending December 31, 1998, and to be modestly accretive for the
financial year ending December 31, 1999. This statement should not be
interpreted to mean that the future earnings per share of Network Associates
Common Stock will necessarily be greater than the earnings per share of Network
Associates for its financial year ended December 31, 1997.

Bill Larson, CEO, Chairman and President of Network Associates, said:

"With today's news, Network Associates further demonstrates its vision and
commitment to deliver world-class enterprise security products to the global
market.

Network Associates is primed to deploy integrated enterprise security systems to
Europe's largest companies."

Geoff Leary, Chief Executive of Dr Solomon's, said:

"I believe that Dr Solomon's and Network Associates represent an excellent fit
in terms of products, markets and infrastructure. The combination should enable
one of the most comprehensive ranges of security products to be made available
to Dr Solomon's customers around the world."

Integration and growth opportunities

Network Associates intends managing the integration of Dr Solomon's as rapidly
and as efficiently as possible. Dr Solomon's Anti-Virus Toolkit 8 is expected to
be shipped on schedule in Fall 1998 and both complete product lines will be
included in Network Associates suites shortly after the transaction closes. In
early 1999, Network Associates expects to begin shipping an upgrade
incorporating the best of Network Associates and Dr Solomon's technology. This
will be a free upgrade to subscribers of either existing product.

Through the Acquisition, Network Associates is expected to benefit from enhanced
growth opportunities including acceleration of growth in the international
security software market, acceleration of the enterprise transition in Europe,
and incorporation of the best elements from both product lines. Further, Network
Associates intends expanding penetration into large European accounts through
the breadth of its product line and the strength of its services and consulting
organisation. Also, Network Associates intends upgrading Dr Solomon's customers
to comprehensive Network Security suites.

Management and employees

Since the two companies compete in many of the same markets with similar product
lines, it is expected that in order to achieve synergistic benefits from the
Acquisition, there will be some rationalisation within the combined workforce.
Transition planning for the merging of the worldwide combined workforce will
begin immediately. Our staff are a major asset of the business and ensuring
their effective and productive deployment will be a key success factor for the
enlarged organisation. Network Associates confirms that existing employment
rights, including pension rights, of the management and all employees of Dr
Solomon's Group will be fully safeguarded.

Dr Solomon's Share Option Schemes

The terms of the Scheme, if approved by Dr Solomon's Shareholders and the Court,
will bind the holders of all Dr Solomon's Ordinary Shares (and the holders of Dr
Solomon's ADSs via the Depositary), including those issued upon exercise of
options, in issue on the day prior to the Effective Date.

Options granted under the Dr Solomon's Company Share Option Scheme 1996 and the
Dr Solomon's Executive Share Option Scheme 1996 (the "1996 Schemes") 
<PAGE>   8


become exercisable during a six month period commencing on the date option
holders are formally notified about the Scheme. Such exercise will be
conditional on the Scheme becoming effective. Options granted under the Dr
Solomon's Group Share Option Scheme will be exercisable for one month following
the date the Scheme becomes effective. As an alternative to exercise, option
holders will be permitted to release their options over Dr Solomon's Ordinary
Shares in consideration for the grant of options of an equivalent value over
shares of Common Stock in Network Associates. As a further alternative, holders
of options granted under the 1996 Schemes will be permitted to cancel their
options and receive Network Associates Common Stock with a value equal to the
latent profit in their options.

1.    by mutual written consent of Dr Solomon's and Network Associates;

2.    by either Dr Solomon's or Network Associates,

(i)   if the Required Shareholders Vote shall not have been obtained at the duly

      obligations of such party under the Transaction Agreement and cannot

      and/or securities, more than 50% of the Dr Solomon's Ordinary Shares then
      outstanding or all or substantially all the assets of Dr Solomon's, and
      otherwise on terms which the Board of Directors of Dr Solomon's determines
      in its good faith reasonable judgement to be more favourable to Dr
      Solomon's stockholders than the Acquisition (after having received the
      advice of Dr Solomon's independent financial adviser as to the value of
      the consideration provided for in such proposal) and for which financing,
      to the extent required, is then committed or which, in the good faith
      reasonable judgement of the Dr Solomon's Board of Directors, is reasonably
      capable of being financed by such third party (a Dr Solomon's Superior
      Proposal) and Dr Solomon's shall have paid to Network Associates the break
      up fee;

4.    by Network Associates:

(i)   if, prior to the Dr Solomon's shareholders meetings, any proposal for
      a merger or other business combination, any scheme of arrangement,
      exchange offer, liquidation, or takeover offer (within the meaning of
      Section 428 of the Companies Act) involving Dr Solomon's or any of its

<PAGE>   13


      securities of or a substantial portion of the assets of Dr Solomon's or
      any of its subsidiaries, or any other similar transactions the
      consummation of which could reasonably be expected to prevent or
      materially impede, interfere with, or delay the Acquisition (a Dr
      Solomon's Acquisition Proposal) is commenced, publicly proposed,
      publicly disclosed or communicated to Dr Solomon's (or the willingness
      of any person to make a Dr Solomon's Acquisition Proposal is publicly
      disclosed or communicated to Dr Solomon's) and the Board of Directors
      of Dr Solomon's or any committee thereof shall have withdrawn or
      modified in a manner adverse to Network Associates its approval or
      recommendation for the Required Shareholders Vote, and approved or
      recommended the Dr Solomon's Acquisition Proposal, or resolved to do
      the foregoing actions;

(ii)  if Dr Solomon's shall have entered into any agreement with respect to any
      Dr Solomon's Superior Proposal; or

(iii) if the Effective Date shall not have occurred on or prior to August 31,
      1998, other than as a result of a material breach of the Transaction
      Agreement by Network Associates or as a result of the failure to satisfy
      the U.S. anti-trust condition in paragraph 3 above (set out in the
      conditions to be satisfied or waived prior to the Final Hearing) prior to
      such date (when such failure shall be the result of a material breach by
      Dr Solomon's of its objections contained in the

      Transaction Agreement).

Payment on Termination

1.    Dr Solomon's shall promptly pay, or cause to be paid, to Network

      Meeting there shall have been no material adverse effect on Network
      Associates) or U.S.$3,500,000, (less any earlier payment) if the

      following any such transaction Dr Solomon's shall consummate a Dr
      Solomon's Acquisition Proposal or enter into any agreement, understanding
      or commitment with respect to a Dr Solomon's Acquisition Proposal and such
      transaction is consummated.

(iv)  U.S. $3,500,000, if the Transaction Agreement is terminated by Network
      Associates in the circumstances set out in (4)(iii) above (provided
      that Network Associates is not in material breach of the Transaction
      Agreement and at the time of such termination there shall have been no
      material adverse effect on Network Associates) and within the nine
      month period following any such termination Dr Solomon's shall
      consummate a Dr Solomon's Acquisition Proposal or enter into any

               LETTER FROM THE CHAIRMAN OF DR SOLOMON'S GROUP PLC
 
[DR SOLOMON'S LETTERHEAD]
26 JUNE 1998
 
     To holders of Dr Solomon's Ordinary Shares and Dr Solomon's ADSs and, for
information only, to participants in the Dr Solomon's Share Option Schemes
 
Dear Shareholder
 
               ACQUISITION OF DR SOLOMON'S BY NETWORK ASSOCIATES
 
INTRODUCTION
 
     On 9 June 1998, the Boards of Dr Solomon's and Network Associates announced
that they had agreed terms for the proposed acquisition of the entire issued
share capital of Dr Solomon's by Network Associates to be effected by means of a
scheme of arrangement under Section 425 of the Companies Act. I am writing to
explain the background to the Acquisition and the reasons why Dr Solomon's
directors consider that the terms of the Acquisition and the Scheme are fair and
reasonable and are unanimously recommending that you approve the Acquisition and
the Scheme.
 
TERMS OF THE ACQUISITION
 
     Under the terms of the Acquisition, holders of Dr Solomon's Ordinary Shares
will receive:
 
          FOR EACH DR SOLOMON'S ORDINARY SHARE
                                            0.27625 SHARES OF NEW NETWORK
                                            ASSOCIATES COMMON STOCK
 
     For holders of Dr Solomon's ADSs, each representing three Dr Solomon's
Ordinary Shares, this is equivalent to:
 
          FOR EACH DR SOLOMON'S ADS
                                            0.82875 SHARES OF NEW NETWORK
                                            ASSOCIATES COMMON STOCK
 
     The Acquisition values the entire current issued share capital of Dr
Solomon's at approximately $642 million (L393 million) and each Dr Solomon's ADS
at $34.81, based on the last sale price of $42.00 per share of Network
Associates Common Stock on NASDAQ on 8 June 1998 (the latest dealing day prior
to the announcement of the Acquisition). On the basis of the last sale price of
$45.31 per share of Network Associates Common Stock on NASDAQ on 23 June 1998,
the Acquisition values the entire current issued share capital of Dr Solomon's
at approximately $692 million (L416 million) and each Dr Solomon's ADS at
$37.55.
 
                                                          DR SOLOMON'S GROUP PLC
                                                 REGISTERED OFFICE: ALTON HOUSE,
                                                                  GATEHOUSE WAY,
                                                                      AYLESBURY,
                                                                BUCKS, HP19 3XU,
                                                                 UNITED KINGDOM.
                                                        HTTP://WWW.DRSOLOMON.COM

     The Acquisition represents a premium of 15.5 per cent. over the average
last sale price of $30.15 of a Dr Solomon's ADS on NASDAQ for the 30 days prior
to the date of the announcement of the Acquisition and a premium of 8.4 per
cent. over the last sale price of $32.125 of a Dr Solomon's ADS on NASDAQ on 8
June 1998. The Acquisition will be a taxable transaction to U.S. holders of Dr
Solomon's Ordinary Shares and Dr Solomon's ADSs. The Acquisition is expected to
be accounted for as a pooling of interests for U.S. accounting purposes.
 
     Immediately following completion of the Acquisition, it is expected that
former holders of Dr Solomon's Ordinary Shares and Dr Solomon's ADSs will hold
approximately 11.7 per cent. of the enlarged Common Stock of Network Associates
(excluding the effect of the exercise of any option, conversion, any other
subscription rights or share issues).
 
     Fractions of new Network Associates Common Stock will not be issued. In
lieu thereof, holders of Dr Solomon's Ordinary Shares and/or Dr Solomon's ADSs
will receive cash (without interest) in an amount equal to the product of such
fractional share of Network Associates Common Stock multiplied by the last sale
price of Network Associates Common Stock on NASDAQ on the Business Day following
the Effective Date.
 
     The new Network Associates Common Stock will be issued fully paid and
non-assessable and will rank pari passu in all respects with the existing
Network Associates Common Stock, including the right to all dividends and other
distributions declared or made after the Effective Date. The new Network
Associates Common Stock will be issued free from all liens, charges,
encumbrances and other interests.
 
     For the nine months ended 28 February 1998, on an unaudited basis, Dr
Solomon's recorded operating profit of L9.6 million (1997: L6.1 million) and net
income of L6.9 million (1997: L2.4 million), based on revenues of L41.5 million
(1997: L25.4 million). For the last four reported quarters, ended 28 February
1998, on an unaudited basis, Dr Solomon's had total bookings of L63.1 million,
representing a 58 per cent. increase over the prior four quarters.
 
     Dr Solomon's is currently reviewing its results of operations for the three
months ended 31 May 1998. Based on preliminary indications, which are subject to
additional review and amendment, bookings for such period were approximately
L20.5 million (compared to L14.8 million for the three months ended 31 May
1997). Dr Solomon's does not currently expect that its financial results for
such period will deviate materially from historical trends adjusted for this
level of bookings.
 
     Dr Solomon's ADSs are quoted on NASDAQ and on EASDAQ. Dr Solomon's had
market capitalisations of $592 million (L362 million) as at 8 June 1998 (the
latest dealing day prior to the announcement of the Acquisition) and $613
million (L368 million) as at 23 June, respectively, based on last sale prices of
$32.125 and $33.25 of a Dr Solomon's ADS on NASDAQ on each of those respective
dates. This represents an 89 per cent. increase and a 96 per cent. increase,
respectively, on the initial public offer price of $17 per Dr Solomon's ADS. The
Dr Solomon's initial public offering was completed in December 1996.
 
     Network Associates Common Stock is quoted on NASDAQ. Network Associates had
market capitalisations of approximately $4.9 billion (L3.0 billion) as at 8 June
1998 (the latest dealing day prior to the announcement of the Acquisition) and
$5.3 billion (L3.2 billion) as at 23 June 1998, respectively, based on last sale
prices of $42.00 and $45.31 per share of Network Associates Common Stock on such
dates.
 
BACKGROUND TO AND REASONS FOR THE ACQUISITION
 
     Over the last few years Network Associates and Dr Solomon's have
periodically discussed potential benefits that could be derived from combining
their respective businesses. Discussions with respect to the Acquisition began
in early 1998 when the parties authorised their financial, legal and accounting
advisors to evaluate various issues and to develop a mutually acceptable
structure for any proposed transaction. In May and early June 1998, the parties
and their advisors conducted due diligence and negotiated the terms for the
Acquisition. As part of its overall plan to acquire the entire issued share
capital of Dr Solomon's, Network Associates purchased 200 Dr Solomon's
 
                                        9
<PAGE>   10
 
ADSs for $32.375 per Dr Solomon's ADS prior to the announcement of the
Acquisition. The Transaction Agreement was signed on 9 June 1998 and a joint
press release announcing the Acquisition was issued on the same day.
 
     The Boards of each of Dr Solomon's and Network Associates believe that Dr
Solomon's and Network Associates represent an excellent fit in terms of
technology, products, markets and infrastructure. The combined group will be one
of the world's largest companies catering primarily to the network security and
management markets, and offering a broad suite of products to protect, manage
and monitor corporate networks for enterprise customers seeking the benefits of
a secure, reliable computing network.
 
     Dr Solomon's strategy for the past two years has been based on three
principal themes: the maintenance of its leadership in anti-virus technology;
the defence and enhancement of its market leadership in the U.K. and Northern
Europe; and achieving sustainable and profitable market shares elsewhere.
 
     Dr Solomon's should benefit from being part of a larger group with a
broader product range and greater overall market strength. Combining Network
Associates' successful marketing, sales, distribution and customer service
expertise with Dr Solomon's infrastructure, leading anti-virus technology,
strong European distribution channels and loyal customer base, should provide
for greater success for the combined companies than is likely to be achieved
separately by either Dr Solomon's or Network Associates. Given the expected
synergies and increased opportunities created by the Acquisition, the Boards of
each of Network Associates and Dr Solomon's believe the Acquisition will be
beneficial to their respective shareholders and customers.
 
MANAGEMENT AND EMPLOYEES
 
     Since the two companies compete in many of the same markets with similar
product lines, it is expected that in order to achieve synergistic benefits from
the Acquisition, there will be some rationalisation within the combined
workforce. Transition planning for the merging of the worldwide combined
workforce has already begun. The staff of the two companies are a major asset of
the businesses and ensuring their effective and productive deployment will be a
key success factor for the enlarged organisation.
 
     Network Associates has confirmed that existing employment rights, including
pension rights, of the management and all employees of the Dr Solomon's Group
will be fully safeguarded.
 
DR SOLOMON'S SHARE OPTION SCHEMES
 
     The terms of the Scheme, if approved by Dr Solomon's Shareholders and the
Court, will bind the holders of all Dr Solomon's Ordinary Shares (including
those issued upon exercise of options) in issue at the Record Time.
 
     Options granted under the 1996 Schemes will become exercisable for a period
of six months from the date on which option holders are formally notified about
the Scheme. Such exercise will be conditional on the Scheme becoming effective.
Options granted under the Group Scheme which are not already exercisable will
become exercisable for one month from the Effective Date. As an alternative to
exercise, option holders will have the opportunity to release their options over
Dr Solomon's Ordinary Shares in consideration for the grant of options of an
equivalent value over shares of Network Associates Common Stock. As a further
alternative, holders of options granted under the 1996 Schemes will have the
opportunity to cancel their options in return for shares of Network Associates
Common Stock.
 
ACTION TO BE TAKEN
 
  HOLDERS OF DR SOLOMON'S ORDINARY SHARES
 
     The proposals require the approval of holders of Dr Solomon's Ordinary
Shares which will be sought at two meetings to be held, the first commencing at
11.00 a.m. (London time), on 21 July 1998 at the offices of Shandwick
Consultants Limited, Aldermary House, 10-15 Queen Street,
 
                                       10
<PAGE>   11
 
London EC4N 1TX. To become effective, the Scheme will also require the
subsequent sanction of the High Court.
 
     Notices of the Court Meeting and the Extraordinary General Meeting are set
out on pages 183 to 186 of this document.
 
     Holders of Dr Solomon's Ordinary Shares are requested to complete and
return the enclosed GREEN and BLUE Forms of Proxy to 10 Norwich Street, London
EC4A 1BD (reference: BRA 545707), so as to be received by no later than 11.00
a.m. (London time) in the case of the GREEN Form of Proxy and by no later than
11.15 a.m. (London time) in the case of the BLUE Form of Proxy, in each case on
19 July 1998. The Form of Proxy for use at the Court Meeting may, however, be
handed to the Chairman of that Meeting prior to commencement of that Meeting.
The return of Forms of Proxy will not preclude holders of Dr Solomon's Ordinary
Shares from attending and voting at the Meetings should they so wish.
 
  HOLDERS OF DR SOLOMON'S ADSS
 
     Holders of Dr Solomon's ADSs may attend the Court Meeting and the
Extraordinary General Meeting, but may not vote in person at either of the
Meetings (unless they become registered holders of Dr Solomon's Ordinary Shares
by arranging for the surrender of their Dr Solomon's ADRs in accordance with the
Deposit Agreement). However, they may instruct The Bank of New York, the
Depositary for the Dr Solomon's ADR programme, how to vote the Dr Solomon's
Ordinary Shares underlying their Dr Solomon's ADSs at the Court Meeting and the
Extraordinary General Meeting. A WHITE Letter of Instruction is enclosed for
this purpose and must be completed, signed and returned to the Depositary at 101
Barclay Street, New York, NY 10286 so as to arrive by no later than 2.00 p.m.
(New York City time) on 16 July 1998.
 
     FAILURE TO RETURN THE FORMS OF PROXY OR THE LETTER OF INSTRUCTION MAY
JEOPARDISE THE PROSPECTS OF THE SCHEME BEING APPROVED AND THE ACQUISITION BEING
COMPLETED. HOLDERS OF DR SOLOMON'S SHARES ARE, THEREFORE, STRONGLY URGED TO
COMPLETE, SIGN AND RETURN THEIR FORMS OF PROXY AND THE LETTER OF INSTRUCTION (AS
RELEVANT) AS SOON AS POSSIBLE.
 
RECOMMENDATION
 
     The directors of Dr Solomon's, who have been so advised by Goldman Sachs
(financial adviser to Dr Solomon's), consider the terms of the Acquisition to be
fair and reasonable. In providing advice to the directors of Dr Solomon's,
Goldman Sachs has taken into account the directors' commercial assessments.
 
     The directors of Dr Solomon's unanimously recommend holders of Dr Solomon's
Ordinary Shares and Dr Solomon's ADSs to approve the Scheme and Acquisition, as
they intend to do in respect of their own beneficial holdings totalling, in
aggregate, 10,125,000 Dr Solomon's Ordinary Shares, representing, in aggregate,
approximately 18.3 per cent. of Dr Solomon's current issued share capital.
 
                                Yours sincerely
 
                                Terence Osborne

                  RECOMMENDED PROPOSAL FOR THE ACQUISITION OF
                       DR SOLOMON'S BY NETWORK ASSOCIATES
 
1. INTRODUCTION
 
     On 9 June 1998, the Boards of Dr Solomon's and Network Associates announced
that they had reached agreement on the terms for an acquisition by Network
Associates of Dr Solomon's entire issued share capital, to be effected by means
of a scheme of arrangement under Section 425 of the Companies Act 1985.
 
     Pursuant to the Scheme and subject to the requisite approvals of Dr
Solomon's Shareholders and the High Court, all of the Dr Solomon's Shares in
issue on a specified date, including the Dr Solomon's Ordinary Shares
represented by the Dr Solomon's ADSs (being the Scheme Shares), will be
cancelled and an equal number of new Dr Solomon's Ordinary Shares will be issued
to Network Associates, leaving Network Associates as Dr Solomon's only
shareholder. In consideration, holders of Scheme Shares will receive new Network
Associates Common Stock according to the exchange offer ratio referred to below.
 
     In the formulation and consideration of this proposal, Dr Solomon's has
been advised by Goldman Sachs and Network Associates has been advised by Morgan
Stanley. We have been authorised by the directors of Dr Solomon's and Network
Associates to write to you to explain the provisions of the Scheme, which is set
out on pages 180 to 182 of this document.
 
     You will see from the letter addressed to you from the Chairman of Dr
Solomon's on pages 8 to 11 above that the directors of Dr Solomon's consider the
terms of the Acquisition and the Scheme to be fair and reasonable. Accordingly,
they have unanimously recommended holders of Dr Solomon's Shares to approve the
proposal, as they intend to do in respect of their own beneficial holdings
totalling, in aggregate, 10,125,000 Dr Solomon's Ordinary Shares, which
represent, in aggregate, approximately 18.3 per cent. of Dr Solomon's current
issued share capital.
 
2. THE CONSIDERATION
 
     Under the Scheme, each Dr Solomon's Ordinary Share in issue at 10.00 p.m.
(London time) on the Business Day immediately prior to the date on which the
Scheme becomes effective (being the Record Time) will be cancelled and an equal
number of new Dr Solomon's Ordinary Shares will be issued to Network Associates
so that Dr Solomon's will become a wholly-owned subsidiary of Network
Associates. As consideration for the Acquisition, Network Associates will issue
to the
 
                                       12
<PAGE>   13
 
holders of Dr Solomon's Ordinary Shares on the share register of Dr Solomon's at
the Record Time shares of new Network Associates Common Stock on the following
basis:
 
<TABLE>
<S>                                               <C>
                                                  0.27625 SHARES OF NEW NETWORK
FOR EACH DR SOLOMON'S ORDINARY SHARE              ASSOCIATES COMMON STOCK
</TABLE>
 
     For holders of Dr Solomon's ADSs (each representing three Dr Solomon's
Ordinary Shares), this is equivalent to:
 
<TABLE>
<S>                                               <C>
                                                  0.82875 SHARES OF NEW NETWORK
FOR EACH DR SOLOMON'S ADS                         ASSOCIATES COMMON STOCK
</TABLE>
 
     Fractions of new Network Associates Common Stock will not be issued. In
lieu thereof, holders of Dr Solomon's Ordinary Shares and/or Dr Solomon's ADSs
will receive cash (without interest) in an amount equal to the product of such
fractional part of Network Associates Common Stock multiplied by the last sale
price of Network Associates Common Stock on NASDAQ on the Business Day following
the Effective Date.
 
     The new Network Associates Common Stock issued in consideration for the
cancellation of Dr Solomon's Ordinary Shares represented by Dr Solomon's ADSs
will be issued to the custodian for the Depositary, and not directly to holders
of Dr Solomon's ADSs. At least one Business Day before the Effective Date, the
Depositary will deliver to the Transfer Agent the names and addresses of the
holders of Dr Solomon's ADRs. Registered holders of Dr Solomon's ADRs will be
requested to surrender their Dr Solomon's ADRs to the Transfer Agent, together
with a properly executed Letter of Transmittal, in exchange for the transfer to
them of new Network Associates Common Stock, together with cheques in relation
to any fractional entitlements arising thereon.
 
     Further particulars of the new Network Associates Common Stock are set out
in Appendices 9 and 10 of this document.
 
     The Acquisition values the entire current issued share capital of Dr
Solomon's at approximately $642 million (L393 million) and each Dr Solomon's ADS
at $34.81, based on the last sale price of $42.00 per share of Network
Associates Common Stock on NASDAQ on 8 June 1998 (the latest dealing day prior
to the date of announcement of the Acquisition). On the basis of the last sale
price of $45.31 per share of Network Associates Common Stock on NASDAQ on 23
June 1998, the Acquisition values the entire current issued share capital of Dr
Solomon's at approximately $692 million (L416 million) and each Dr Solomon's ADS
at $37.55. The Acquisition represents a premium of 15.5 per cent. over the
average last sale price of $30.15 of a Dr Solomon's ADS on NASDAQ for the 30
days prior to the date of the announcement of the Acquisition and a premium of
8.4 per cent. over the last sale price of $32.125 for a Dr Solomon's ADS on
NASDAQ on 8 June 1998.
 
     Immediately following completion of the Acquisition, it is expected that
former holders of Dr Solomon's Ordinary Shares and Dr Solomon's ADSs will hold
approximately 11.7 per cent. of the enlarged Common Stock of Network Associates
(excluding the effect of the exercise of any option, conversion, or other
subscription rights or further share issues).
 
     As part of its overall plan to acquire the entire issued share capital of
Dr Solomon's, Network Associates purchased 200 Dr Solomon's ADSs for $32.375 per
Dr Solomon's ADS prior to the announcement of the Acquisition and intends to
make further purchases (subject to applicable securities laws) of a small number
of Dr Solomon's Ordinary Shares and/or Dr Solomon's ADSs (representing no more
than 600 underlying Dr Solomon's Ordinary Shares) prior to the Effective Date.
Network Associates intends that, immediately following the Effective Date,
Network Associates will transfer all or a portion of the Dr Solomon's Ordinary
Shares owned by it to a direct or indirect subsidiary.

<PAGE>   14
 
DIVIDENDS
 
     No dividends will be declared or paid on the Dr Solomon's Ordinary Shares
prior to their cancellation under the Scheme.
 
GENERAL
 
     Application is being made to NASDAQ for the new Network Associates Common
Stock to be listed on NASDAQ as soon as possible following the Effective Date.
 
     The new Network Associates Common Stock will be issued as fully paid and
non-assessable and will rank pari passu in all respects with the existing
Network Associates Common Stock, including the right to all dividends and the
distributions declared or made after the Effective Date. The new Network
Associates Common Stock will be issued free from all liens, charges,
encumbrances and other interests.
 
3. CONDITIONS OF THE SCHEME
 
     The terms and conditions of the Scheme, and the obligations of Dr Solomon's
and Network Associates to implement the Scheme which are governed by the
Transaction Agreement, comply with the appropriate regulations of the City Code.
The Scheme is expected to become effective on 13 August 1998.
 
     The Scheme is conditional, inter alia, upon:
 
          (a)  approval of the Scheme by a majority in number representing at
     least 75 per cent. in value of the holders of Dr Solomon's Ordinary Shares
     present and voting in person or by proxy at the Court Meeting;
 
          (b)  the special resolution required to implement the Scheme and amend
     the Articles of Association of Dr Solomon's being passed at the
     Extraordinary General Meeting;
 
          (c)  the approval for listing on NASDAQ of the new Network Associates
     Common Stock;
 
          (d)  the Office of Fair Trading indicating prior to the Final Hearing,
     in terms satisfactory to Network Associates, that it is not the intention
     of the Secretary of State for Trade and Industry to refer the Acquisition,
     or any matters arising therefrom, to the Monopolies and Mergers Commission;
 
          (e)  any applicable waiting period and any extension to such period
     under the HSR relating to the Acquisition having expired or been
     terminated;
 
          (f)  Dr Solomon's having received, in a form reasonably acceptable to
     the directors of Dr Solomon's, clearance from the Inland Revenue under
     Section 138 of the Taxation of Chargeable Gains Act 1992 for the
     transactions involved in the Scheme;
 
          (g)  Networks Associates having received letters from each of Coopers
     & Lybrand LLP and Deloitte & Touche respectively regarding that firm's
     concurrence with the conclusions of the management of Networks Associates
     and Dr Solomon's as to the appropriateness of pooling of interest
     accounting for the Scheme under U.S. Accounting Principles Board Opinion
     No. 16;
 
          (h)  the grant of the Final Court Order; and
 
          (i)  the delivery to the Registrar of an office copy of the Final
     Court Order and registration of the same.
 
     Network Associates and Dr Solomon's will not proceed with the Scheme if,
prior to 5.30 p.m. (London time) on the date of the Meetings, the Secretary of
State for Trade and Industry refers the Acquisition, or any matters arising
therefrom, to the Monopolies and Mergers Commission. In such
 
                                       14
<PAGE>   15
 
event, neither Network Associates nor any holder of Dr Solomon's Shares will be
bound by any term or condition of the Scheme. However, neither of the Boards of
Dr Solomon's or Network Associates have any reason to believe that the
Acquisition will be referred to the Monopolies and Mergers Commission.
 
     The conditions to implementation of the Scheme are set out in full in
Appendix 1 of this document. Subject to such conditions being satisfied (or
waived), it is expected that the Effective Date will be on or about 13 August
1998, with certificates representing the new Network Associates Common Stock and
cheques in respect of any relevant fractional entitlements being posted to
holders of Dr Solomon's Ordinary Shares by 20 August 1998 and with Letters of
Transmittal being posted to holders of Dr Solomon's ADSs by 20 August 1998.
 
     Under the terms of the Scheme, Dr Solomon's will reduce its share capital
by the cancellation of the Scheme Shares. The reserve arising on the
cancellation of the Scheme Shares will be capitalised by the issue to Network
Associates of a corresponding number of new Dr Solomon's Ordinary Shares so that
Dr Solomon's becomes a wholly-owned subsidiary of Network Associates.
 
     In addition, the Acquisition is intended to qualify as a pooling of
interests for U.S. financial reporting purposes in accordance with U.S. GAAP.
Completion of the Acquisition is conditional upon receipt at the closing of the
Acquisition by Network Associates and Dr Solomon's of letters from Coopers &
Lybrand LLP, Network Associates' independent public accountants, and Deloitte &
Touche, Dr Solomon's independent public accountants, regarding their respective
concurrence with the conclusion of the management of each of Network Associates
and Dr Solomon's, as to the use of pooling of interest accounting for the
Acquisition under U.S. Accounting Principle Bulletin Number 16, if the Scheme is
consummated in accordance with the Transaction Agreement.
 
     THE ACQUISITION WILL NOT QUALIFY AS A TAX-FREE TRANSACTION FOR U.S. PERSONS
WHO ARE DR SOLOMON'S SHAREHOLDERS AND WILL BE TAXABLE UNDER U.S. TAX LAWS TO
SUCH DR SOLOMON'S SHAREHOLDERS. SEE PARAGRAPH 11(A) BELOW.
 
     Announcements of the results of the Court Meeting, the Extraordinary
General Meeting and the Final Hearing will be made as soon as practicable after
the Meetings and the Final Hearing, respectively.
 
     Further details of the conditions of the Scheme and the other terms of the
Transaction Agreement are set out in Appendix 1 of this document. The Board of
Dr Solomon's will not take the necessary steps to make the Scheme effective
unless all the conditions to Network Associates' obligation to proceed with the
Acquisition are fulfilled or waived immediately prior to the date of the Final
Hearing.
 
     The Scheme will become effective when a copy of the Final Court Order is
registered by the Registrar, at which time Network Associates will own the
entire issued share capital of Dr Solomon's. The Scheme will lapse if it does
not become effective by 31 August 1998 (or such later date as the parties agree
and the Court may allow, being not later than 31 December 1998).
 
     IT IS EXPECTED THAT THE SCHEME WILL BECOME EFFECTIVE ON 13 AUGUST 1998.
UPON THE SCHEME BECOMING EFFECTIVE, IT WILL BE BINDING ON ALL HOLDERS OF DR
SOLOMON'S ORDINARY SHARES AS AT THE RECORD DATE IRRESPECTIVE OF WHETHER THEY
ATTENDED OR VOTED AT THE COURT MEETING.
 
4. INFORMATION ON DR SOLOMON'S
 
HISTORY OF DR SOLOMON'S
 
     Dr Solomon's, a leading supplier of anti-virus software in the U.K. and
elsewhere in Europe, develops, markets and supports anti-virus and other
software programs for PCs and PC networks, Macintosh and UNIX systems. Dr
Solomon's products provide effective and easy-to-use software solutions to the
risks posed by the proliferation of new and increasingly sophisticated types of
 
                                       15
<PAGE>   16
 
computer viruses. Dr Solomon's principal product line is the "Dr Solomon's
Anti-Virus Toolkit" family of anti-virus software programs. Since its
introduction in 1989, the Toolkit has become one of the leading global
anti-virus software programs. The most recent version of the Toolkit can detect
and identify more than 19,000 known computer viruses.
 
     Dr Solomon's targets its sales and marketing efforts primarily at medium
and large corporate customers with networks of PCs. A substantial percentage of
Dr Solomon's sales are in the form of recurring revenues from corporate
licenses. Dr Solomon's has over 150 people working in sales and approximately 60
third party international partners. Dr Solomon's products include award winning
virus detection engine technology and feature-rich anti-virus management
technology.
 
     For the nine months ended 28 February 1998, on an unaudited basis, Dr
Solomon's recorded operating profit of L9.6 million (1997: L6.1 million) and net
income of L6.9 million (1997: L2.4 million), based on revenues of L41.5 million
(1996: L25.4 million). For the last four reported quarters, ended 28 February
1998, on an unaudited basis, Dr Solomon's had total bookings of L63.1 million,
representing a 58 per cent. increase over the prior four quarters.
 
     Dr Solomon's ADSs are quoted on NASDAQ and on EASDAQ. Dr Solomon's had
market capitalisations of $592 million (L362 million) as at 8 June 1998 (the
latest dealing day prior to the announcement of the Acquisition), and $613
million (L368 million) as at 23 June 1998, respectively, based on last sale
prices of $32.125 and $33.25 respectively of a Dr Solomon's ADS on NASDAQ on
those dates. This represents an 89 per cent. and a 96 per cent. increase
respectively on the initial public offering price of $17 per Dr Solomon's ADS.
The initial public offering was completed in December 1996.
 
     Further information concerning Dr Solomon's is set out in Appendices 2, 4,
10 and 11 of this document.
 
5. INFORMATION ON NETWORK ASSOCIATES
 
     With headquarters in Santa Clara, California, Network Associates, formed
late last year by the merger of McAfee Associates, Inc. and Network General
Corporation, is a leading supplier of enterprise network security and management
solutions. Network Associates focuses on providing broad and integrated network
security and management software products for enterprise customers, targeting in
particular the Windows NT/Intel platform. Network Associates' customer base
includes a significant number of Fortune 500 companies. Its PGP encryption and
authentication technology is considered a worldwide standard for internet email
and file encryption. Network Associates offers a comprehensive suite of network
security products under the Net Tools Secure product suite including the Total
Virus Defense suite ("TVD suite") of anti-virus products, featuring a
multi-tiered approach to virus detection and eradication, and the Total Network
Security suite of products including encryption, intrusion detection,
authentication, and firewall products. Network Associates was one of the first
anti-virus providers on the market to attack virus infection through a
multi-tiered approach with the TVD suite. Network Associates' Net Tools Manager
product suite includes the Total Network Visibility suite of network fault and
performance solutions and the Total Service Desk suite of integrated service
desk solutions.
 
     Network Associates' four product suites are sold under a product umbrella
called Net Tools. Net Tools is being designed as a fully integrated product
offering intended to reduce the total cost of managing an enterprise network.
 
     Many of Network Associates network security and management products are
available on a stand-alone basis. Network Associates is also a leader in
electronic software distribution, which is the principal means by which it
markets and distributes its software products to its customers.
 
     For the year ended 31 December 1997, Network Associates recorded operating
profit of $194.0 million (1996: $136.5 million) (pre-acquisition and related
costs) and net income of $147.4 million (1996: $94.8 million) (pre-acquisition
and related costs), based on revenues of $612.2 million (1996: $421.8 million).
For the year ended 31 December 1997, revenue growth for
 
                                       16
<PAGE>   17
 
1997 was 45 per cent. As of 31 March 1998, Network Associates had $782.5 million
in cash and marketable securities and $77 million in deferred revenue.
 
     On 29 May 1998, Network Associates effected the Network Associates 3-for-2
Stock Split.
 
     Network Associates Common Stock is quoted on NASDAQ. Network Associates had
a market capitalisation of approximately $4.9 billion as at 8 June 1998 (the
latest dealing day prior to the announcement of the Acquisition) and $5.3
billion as at 23 June, respectively, based on last sale prices of $42.00 and
$45.31 per share, respectively, of Network Associates Common Stock on those
dates.
 
     In April 1998 Network Associates acquired Magic Solutions, a privately held
provider of internal help desk and asset management solutions, and TIS, a
publicly held provider of comprehensive security systems for computer networks,
for approximately $110 million in cash and $300 million in Network Associates
Common Stock, respectively.
 
6. BACKGROUND TO AND REASONS FOR THE ACQUISITION
 
     Over the last few years, Network Associates and Dr Solomon's have
periodically discussed potential benefits that could be derived from combining
their respective businesses. Discussions with respect to the Acquisition began
in early 1998 when the parties authorised their financial, legal and accounting
advisors to evaluate various issues and to develop a mutually acceptable
structure for any proposed transaction. In May and early June 1998, the parties
and their advisors conducted due diligence and negotiated the terms for the
Acquisition. As part of its overall plan to acquire the entire issued share
capital of Dr Solomon's, Network Associates purchased 200 Dr Solomon's ADSs for
$32.375 per Dr Solomon's ADS prior to the announcement of the Acquisition. The
Transaction Agreement was signed on 9 June 1998 and a joint press release
announcing the Acquisition was issued on the same day.
 
     The Boards of each of Dr Solomon's and Network Associates believe that Dr
Solomon's and Network Associates represent an excellent fit in terms of
technology, products, markets and infrastructure. The combined group will be one
of the world's largest companies catering primarily to the network security and
management markets, and offering a broad suite of products to protect, manage
and monitor corporate networks for enterprise customers seeking the benefits of
a secure, reliable computing network.
 
     The Acquisition builds on the foundation of Network Associates' core
strengths and extends its popular anti-virus technology, which evolved from its
flagship product, McAfee VirusScan, an industry leader. Network Associates' core
strengths include its broad product line, its position in the rapidly growing
security market, its scale, its high quality services organisation with 85
seasoned security consultants, its installed base with over 50 million units
distributed and its award-winning global virus research team with laboratories
on 5 continents. Shortly after the Acquisition, Dr Solomon's Anti-Virus Toolkit
is expected to be available as part of Network Associates' enterprise security
suites, the TVD suite, and Net Tools Secure, the only integrated software bundle
on the market to incorporate anti-virus, encryption, authentication, firewall,
intrusion detection and scanning technology.
 
     Dr Solomon's strategy for the past two years has been based on three
principal themes: the maintenance of its leadership in anti-virus technology;
the defence and enhancement of its market leadership in the U.K. and Northern
Europe; and achieving sustainable and profitable market shares elsewhere.
 
     The combination will provide Network Associates with the potential to
access Dr Solomon's strong European distribution channels, to benefit from Dr
Solomon's strategic product technologies, to strengthen Network Associates'
suite of integrated security products and to achieve significant distribution
channel and services synergies.
 
                                       17
<PAGE>   18
 
     Dr Solomon's should benefit from being part of a larger group with a
broader product range and greater overall market strength. Combining Network
Associates' successful marketing, sales, distribution and customer service
expertise with Dr Solomon's infrastructure, leading anti-virus technology,
strong European distribution channels and loyal customer base, should provide
for greater success for the combined companies than is likely to be achieved
separately by either Dr Solomon's or Network Associates. Given the expected
synergies and increased market opportunities created by the Acquisition, the
Boards of each of Network Associates and Dr Solomon's believe the Acquisition
will be beneficial to their respective shareholders and customers.
 
     There are a number of risks associated with the Acquisition and the ability
to achieve the contemplated benefits thereof. See Appendix 7 -- "Risk
Factors -- Risks Related to the Acquisition."
 
     The Board of Network Associates expects that it will incur a one time
charge in the third quarter of 1998, resulting from expenses and other charges
associated with the Acquisition. Excluding this one time charge, the Board of
Network Associates expects the Acquisition to be modestly dilutive to earnings
per share in the third quarter of its financial year ending 31 December 1998,
but is expected to be non-dilutive to earnings per share in the fourth quarter
of its financial year ending 31 December 1998, and to be modestly accretive to
earnings per share for the financial year ending 31 December 1999. This
statement should not be interpreted to mean that the future earnings per share
of Network Associates Common Stock will necessarily be greater than the earnings
per share of Network Associates Common Stock for its financial year ended 31
December 1997.
 
7. PRODUCT INTEGRATION AND GROWTH OPPORTUNITIES
 
     Network Associates intends managing the integration of Dr Solomon's as
rapidly and as efficiently as possible. Dr Solomon's Anti-Virus Toolkit 8 is
expected to be shipped on schedule in Fall 1998 and both it and McAfee's
VirusScan product lines are expected to be included in Network Associates'
suites shortly after the Effective Date.
 
     Through the Acquisition, Network Associates expects to benefit from
enhanced growth opportunities including acceleration of growth in the
international security software market, acceleration of the enterprise
transition in Europe, and incorporation of the best elements from both
companies' product lines. Further, Network Associates intends expanding
penetration into large European accounts through the breadth of its product line
and the strength of its services and consulting organisation. Also, Network
Associates intends upgrading Dr Solomon's customers to comprehensive Network
Security suites.
 
     See Appendix 7, "Risk Factors -- Risks Related to the
Acquisition -- Difficulties of Integrating Two Companies", for a discussion of
the risks inherent in integrating the two companies.
 
8. DIRECTORS, MANAGEMENT AND EMPLOYEES
 
     Since the two companies compete in many of the same markets with similar
product lines, it is expected that in order to achieve synergistic benefits from
the Acquisition, there will be some rationalisation within the combined
workforce. Transition planning for the merging of the worldwide combined
workforce will begin immediately. The staff of the two companies are a major
asset of the businesses and ensuring their effective and productive deployment
will be a key success factor for the enlarged organisation. It has been agreed
that all of the directors of Dr Solomon's will resign from the Board on the
Effective Date.
 
     Network Associates confirms that existing employment rights, including
pension rights, of the management and all employees of the Dr Solomon's Group
will be fully safeguarded.
 
     The interests of the directors of Dr Solomon's in Dr Solomon's Shares are
set out in Appendix 11 of this document. The effect of the Scheme on the
interests of the directors of Dr Solomon's is no different from the effect of
the Scheme on the like interests of other persons,
                                       18
<PAGE>   19
 
save with regard to their interests as option holders (as described in paragraph
12 below and Appendix 11) and the requirement that they enter into Affiliate
Agreements (as described in paragraph 9 below).
 
     The directors of Dr Solomon's intend to vote in favour of the resolutions
to be proposed at the Court Meeting and the Extraordinary General Meeting in
respect of the Dr Solomon's Ordinary Shares held by them which amount to, in
aggregate, 10,125,000 Dr Solomon's Ordinary Shares which represent, in
aggregate, approximately 18.3 per cent. of Dr Solomon's current issued share
capital.
 
     See Appendix 7, "Risk Factors -- Risks Related to the
Acquisition -- Dependence on Key Personnel".
 
9. STATUS OF NEW NETWORK ASSOCIATES COMMON STOCK UNDER THE SECURITIES LAWS AND
POOLING RULES; AFFILIATES
 
     The new Network Associates Common Stock will not be registered under the
Securities Act, in reliance upon the exemption from the registration
requirements of the Securities Act provided by Section 3(a)(10) thereof. Shares
of new Network Associates Common Stock issued to a Dr Solomon's Shareholder who
is neither an affiliate, for the purposes of the Securities Act, of Dr Solomon's
prior to implementation of the Scheme nor an affiliate of Network Associates
after implementation of the Scheme may be resold without restriction under the
Securities Act. Dr Solomon's Shareholders who are affiliates of Dr Solomon's
prior to implementation of the Scheme but will not be affiliates of Network
Associates after implementation of the Scheme will be subject to the timing,
manner of sale and volume restrictions on the sale of shares of new Network
Associates Common Stock for a one year period pursuant to Rule 145(d) under the
Securities Act. For the purposes of the Securities Act, "affiliates" are
generally defined as persons who control, or are controlled by, or are under
common control with Network Associates or Dr Solomon's (generally, certain
executive officers and directors and principal shareholders thereof). The
Transaction Agreement provides that each of the Dr Solomon's Shareholders who
may be deemed to be affiliates of Dr Solomon's will execute and deliver to
Network Associates an agreement (an "Affiliate Agreement") acknowledging that
such person may be deemed to be an affiliate of Dr Solomon's and agreeing that
such person will not sell, pledge, transfer or otherwise dispose of any new
Network Associates Common Stock obtained as a result of the Acquisition except
in compliance with the Securities Act and the rules and regulations of the
Commission thereunder.
 
     In addition, in order that Network Associates may obtain the benefit of
accounting for the Acquisition as a pooling of interests under U.S. GAAP, Dr
Solomon's Shareholders who may be deemed to be affiliates of Dr Solomon's will
agree in their Affiliate Agreement that such person will not sell, pledge,
transfer or otherwise dispose of any Dr Solomon's Shares or Network Associates
Common Stock, respectively, during the period commencing 30 Business Days prior
to the Effective Date and ending upon the publication by Network Associates of
financial results relating to the combined company covering a period of at least
30 days of combined operations of Network Associates and Dr Solomon's. Network
Associates will ensure that persons who may be deemed to be affiliates of
Network Associates will also be subject to such restriction.

       (b) In calculating the increase:
 
           (i) no account has been taken of any liability to taxation or for

               and
 
           (ii) it is assumed that fractional shares of Network Associates

(B) DIVIDEND POLICY
 
     Dr Solomon's has not paid any cash dividends on its issued share capital
since its initial public offering in December 1996. It is the current policy of
the Board of Dr Solomon's to retain all of its future earnings to finance its
operations and future growth.
 
     Network Associates has not paid any cash dividends on its issued common
stock since its initial public offering on 6 October 1992. Network Associates
intends to retain future earnings for use in its business and does not
anticipate paying cash dividends in the foreseeable future.
 
11. TAXATION
 
(A) U.S. TAXATION
 
     The following discussion summarizes the material United States federal
income tax consequences to U.S. Holders (as defined below) of the Scheme and of
the ownership and disposition of new Network Associates Common Stock received in
the Scheme. This summary is based upon the United States Internal Revenue Code
of 1986, as amended (the "Code"), its legislative history, final, temporary and
proposed regulations promulgated thereunder, published rulings of the Internal
Revenue Service and court decisions, all as currently in effect and all of which
are subject to change possibly with retroactive effect. This summary assumes
that holders of Dr Solomon's Ordinary Shares hold such shares and will hold new
Network Associates Common Stock as capital assets (generally, assets held for
investment). The summary does not address all aspects of United States federal
income taxation, nor does it address all aspects of United States federal income
taxation that may apply to particular Dr Solomon's Shareholders, such as
shareholders who are dealers in securities, foreign persons, or those that
acquired their shares as compensation or those that have engaged in conversion
straddles or similar transactions. This discussion also does not address the
United States federal income tax treatment to holders of options or warrants to
purchase Dr Solomon's Ordinary Shares. In addition, this summary does not
address any United States state or local or foreign tax consequences of the
Scheme.
 
     As used herein, a U.S. Holder means (i) citizens or residents of the United
States, (ii) corporations, partnerships or other entities organised or created
in or under the laws of the
 
                                       20
<PAGE>   21
 
United States or any political subdivision thereof, (iii) estates the income of
which is subject to United States federal income tax regardless of its source
and (iv) trusts subject to the primary supervision of a court within the United
States and the control of a United States person. A Non-U.S. Holder is any
holder other than a U.S. Holder.
 
     THIS SUMMARY IS FOR GENERAL PURPOSES ONLY AND IS NOT INTENDED TO ADDRESS
ALL OF THE UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS THAT MAY APPLY TO A
PARTICULAR DR SOLOMON'S SHAREHOLDER. DR SOLOMON'S SHAREHOLDERS SHOULD CONSULT
THEIR TAX ADVISORS WITH RESPECT TO THE UNITED STATES FEDERAL, STATE, LOCAL AND
FOREIGN TAX CONSEQUENCES OF THE SCHEME.
 
     THE SCHEME. The directors of Dr Solomon's have been advised that the
exchange of Dr Solomon's Ordinary Shares for new Network Associates Common Stock
pursuant to the Scheme will constitute a taxable transaction for United States
federal income tax purposes. Accordingly, a U.S. Holder who receives new Network
Associates Common Stock in exchange for Dr Solomon's Ordinary Shares will
recognise taxable gain or loss in an amount equal to the difference between the
sum of (A) the fair market value of new Network Associates Common Stock received
and (B) the amount of cash received in lieu of fractional shares of new Network
Associates Common Stock, and the adjusted basis of the Dr Solomon's Ordinary
Shares surrendered in the exchange. Such gain or loss will be capital gain or
loss and will be long-term capital gain or loss if the Dr Solomon's Ordinary
Shares exchanged have been held for more than one year on the Effective Date.
Under the Code, the net amount of such capital gain recognised by a
non-corporate U.S. Holder generally will be subject to tax at a maximum rate of
(i) 20 per cent., if the Dr Solomon's Ordinary Shares were held for more than 18
months, (ii) 28 per cent., if the Dr Solomon's Ordinary Shares were held for
more than 12 months but not more than 18 months or (iii) 39.6 per cent., if the
Dr Solomon's Ordinary Shares were held for 12 months or less. The deductibility
of capital losses is subject to limitations.
 
     Any such gain generally will be treated as United States source income for
purposes of the rules applicable to the limitations on foreign tax credits. It
is unclear whether a loss would be treated as United States source loss or
foreign source loss.
 
     OWNERSHIP OF NETWORK ASSOCIATES COMMON STOCK. U.S. Holders will have a tax
basis in the new Network Associates Common Stock received equal to the fair
market value of the new Network Associates Common Stock on the Effective Date.
The holding period of the new Network Associates Common Stock will begin on the
day after the Effective Date.
 
     Cash distributions on the new Network Associates Common Stock paid out of
earnings and profits will be subject to tax as ordinary dividend income. Cash
distributions on the Network Associates Common Stock in excess of current or
accumulated earnings and profits will be treated as tax-free return of capital
to the extent of the U.S. Holder's adjusted tax basis in the new Network
Associates Common Stock, and thereafter as gain from the sale or exchange of a
capital asset (which gain will be taxed in the manner described above under "The
Scheme").
 
     On the sale, exchange or other disposition of new Network Associates Common
Stock, a U.S. Holder will recognize capital gain or loss equal to the difference
between the amount realized on the sale, exchange or other disposition and the
U.S. Holder's tax basis in such Network Associates Common Stock (which gain or
loss will be taxed in the manner described above under The Scheme).
 
     NON-U.S. HOLDERS. A Non-U.S. Holder of Dr Solomon's Ordinary Shares
generally will not be subject to United States federal income tax on gain
realized on the receipt of the new Network Associates Common Stock, or upon a
subsequent exchange (or sale) of the new Network Associates Common Stock, unless
(i) such gain is effectively connected with a United States trade or business
(or in the case of Non-U.S. Holders entitled to the benefits of the United
Kingdom -- United States Income Tax Convention as in effect on the date of these
documents (the "Treaty"), or another income tax treaty that requires a permanent
establishment in the United States as a basis
 
                                       21
<PAGE>   22
 
for taxing such gains, such gain is attributable to a permanent establishment in
the United States) or (ii) in the case of gain recognised by an individual upon
a subsequent exchange (or sale) of the new Network Associates Common Stock, such
individual is present in the United States for 183 days or more in the taxable
year of such exchange (or sale) and certain other conditions are met.
 
     Dividends received by a Non-U.S. Holder with respect to new Network
Associates Common Stock generally will be subject to United States withholding
tax at the rate of 30 per cent., which rate may be subject to reduction by an
applicable income tax treaty in effect between the United States and the
Non-U.S. Holder's country of residence. Under the Treaty, the rate of
withholding tax is generally reduced to 15 per cent. in respect of dividends
paid to a person who is the beneficial owner thereof and who is a resident of
the United Kingdom for the purposes of the Treaty.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING.
 
     U.S. HOLDERS.  Information reporting will apply to payments of dividends on
and the proceeds of the sale or other disposition of Networks Associates Common
Stock to certain noncorporate U.S. Holders, and backup withholding at a rate of
31 per cent. may apply unless the U.S. Holder supplies a taxpayer identification
number, certified under penalties of perjury, as well as certain other
information or otherwise establishes an exemption from backup withholding. A
U.S. Holder who does not provide its correct tax identification number ("TIN")
also may be subject to penalties imposed by the IRS. Any amount withheld from a
payment to a U.S. Holder under the backup withholding rules is creditable
against the holder's federal income tax liability, provided that the required
information is furnished to the IRS.
 
     NON-U.S. HOLDERS.  The Company must report annually to the IRS and to each
Non-U.S. Holder any dividend that is subject to withholding, or that is exempt
from U.S. withholding tax pursuant to a tax treaty. Copies of these information
returns may also be made available under the provisions of a specific treaty or
agreement to the tax authorities of the country in which the Non-U.S. Holder
resides.
 
     The payment of the proceeds from the disposition of Network Associates
Common Stock to or through the U.S. office of any broker, U.S. or foreign, will
be subject to information reporting and possible backup withholding unless the
owner certifies as to its Non-U.S. Holder status under penalty of perjury or
otherwise establishes an exemption, provided that the broker does not have
actual knowledge that the holder is a U.S. person or that the conditions of any
other exemption are not, in fact, satisfied. The payment of the proceeds from
the disposition of new Network Associates Common Stock to or through a non-U.S.
office of a non-U.S. broker that is not a U.S. related person will not be
subject to information reporting or backup withholding (absent actual knowledge
that the payee is a U.S. person). For this purpose, a "U.S. related person" is
(i) a "controlled foreign corporation" for U.S. federal income tax purposes,
(ii) a foreign person 50 per cent. or more of whose gross income from all
sources for the three-year period ending with the close of its taxable year
preceding the payment (or for such part of the period that the broker has been
in existence) is derived from activities that are effectively connected with the
conduct of a U.S. trade or business, or (iii) with respect to payments made
after 31 December 1999, a foreign partnership that, at any time during its
taxable year, is 50 per cent. or more (by income or capital interest) owned by
United States persons or is engaged in the conduct of a U.S. trade or business.
In the case of the payment of proceeds from the disposition of Network
Associates Common Stock to or through a non-U.S. office of a broker that is
either a U.S. person or U.S. related person, information reporting (but not
backup withholding) is required on the payment unless the broker has documentary
evidence in its files that the owner is a Non-U.S. Holder and the broker has no
knowledge to the contrary.
 
                                       22

(B) U.K. TAXATION
 
     The following paragraphs, which are intended as a general guide only, are
based on current U.K. legislation and what is understood to be U.K. Inland
Revenue practice and take account of certain changes announced in the Budget
Statement of 17 March 1998 which are contained in the Finance (No. 2) Bill (the
"Finance Bill") currently before the U.K. Parliament. They summarise certain
limited aspects of the U.K. tax consequences of the Scheme, and they relate only
to the position of certain classes of taxpayer and only those Dr Solomon's
Shareholders who hold their Dr Solomon's Ordinary Shares beneficially as an
investment and who are resident in the U.K. for tax purposes. If you are in any
doubt as to your tax position or if you are subject to tax in any jurisdiction
other than the U.K., you should consult an appropriate professional adviser
immediately.
 
     THE SCHEME.  A holder of Dr Solomon's Ordinary Shares who is within the
scope of UK tax on capital gains and who, either alone or together with persons
connected with him, does not hold more than 5 per cent., of, or of any class of,
the shares in or debentures of Dr Solomon's should not be treated as having made
a disposal of his/her Dr Solomon's Ordinary Shares for the purposes of U.K. tax
on capital gains to the extent that he receives new Network Associates Common
Stock pursuant to the Scheme. Any such holder of Dr Solomon's Ordinary Shares
who, either alone or together with persons connected with him, holds more than 5
per cent. of, or of any class of, the shares in or debentures of Dr Solomon's is
advised that an application for clearance has been made to the U.K. Inland
Revenue under section 138 of the Taxation of Chargeable Gains Act 1992 in
respect of the Scheme. If such clearance is given, any such shareholder will be
treated in the same manner as a shareholder holding not more than 5 per cent.
of, or of any class of, the shares in or debentures of Dr Solomon's as outlined
above. The obligations of Dr Solomon's to effect the Scheme are subject, inter
alia, to Dr Solomon's having received, in a form reasonably acceptable to the
directors of Dr Solomon's, clearance from the Inland Revenue under Section 138
of the Taxation of Chargeable Gains Act 1992 for transactions involved in the
Scheme. In the event that clearance is not given by the Inland Revenue, Dr
Solomon's has the option to waive this condition to the implementation of the
Scheme.
 
     Such a holder of Dr Solomon's Ordinary Shares will, to the extent that he
or she receives cash from Network Associates under the Scheme in respect of a
fractional entitlement, be treated as making a part disposal of his Dr Solomon's
Ordinary Shares for the purposes of U.K. tax on capital gains and, accordingly,
he or she may be liable to such tax on any chargeable gain arising. For this
purpose, the capital gains tax base of such shareholder's Dr Solomon's Ordinary
Shares will generally be apportioned by reference to market value at the date of
disposal between the part deemed disposed of and the part retained (subject to
indexation allowance and as reduced by any available taper relief).
 
     For the purposes of U.K. tax on capital gains the holder of an ADR is
treated as holding a beneficial interest in the underlying shares and
accordingly, in practice, no liability to U.K. tax on capital gains is likely to
arise on the surrender of ADRs for new Network Associates Common Stock pursuant
to the Scheme.
 
     OWNERSHIP OF NETWORK ASSOCIATES COMMON STOCK
 
     Capital gains.  A shareholder who is neither resident nor ordinarily
resident in the U.K. will not be subject to tax in the U.K. on capital gains on
a disposal of Network Associates Common Stock. A shareholder who is
"temporarily" non-resident in the U.K. for a period of fewer than five complete
tax years may, however, be treated as though his gain accrued upon his return to
the U.K.
 
     Shareholders who are either resident or ordinarily resident in the U.K.
will, in general, be subject to U.K. tax on capital gains on a disposal of
Network Associates Common Stock. However, shareholders who are individuals and
who are resident or ordinarily resident in the U.K. but who are not domiciled in
the U.K. will not be subject to U.K. tax on capital gains arising on a disposal
of
 
                                       23
<PAGE>   24
 
Network Associates Common Stock unless they remit (or, for tax purposes, are
treated as remitting) the proceeds of the disposal to the U.K.
 
     Dividends.  A shareholder who is not resident in the U.K. for U.K. tax
purposes will not be liable to income or corporation tax in the U.K. on any
dividends paid on Network Associates Common Stock by Network Associates unless
the shareholder carries on business in the U.K. through a branch or agency to
which the Network Associates Common Stock is attributable.
 
     Shareholders who are resident in the U.K. will, in general, be subject to
U.K. income tax or corporation tax on dividends paid by Network Associates. No
such liability will arise for individual shareholders who, though U.K. resident,
are not domiciled in the U.K., or for Commonwealth citizens or citizens of the
Republic of Ireland who are not ordinarily resident in the U.K., except to the
extent that amounts are remitted to the U.K. (or are treated for tax purposes as
remitted to the U.K.). Credit will be available against U.K. income or
corporation tax for any US tax withheld from the dividends, up to the maximum
amount of withholding permitted by the Treaty.
 
     Where a person in the U.K. in the course of a trade or profession either:
 
          (i) acts as a custodian of the Network Associates Common Stock and
     receives dividends thereon, or directs that dividends on the Network
     Associates Common Stock be paid to another person, or consents to such
     payment;
 
          (ii) collects or secures payment of or receives dividends on the
     Network Associates Common Stock for another person (other than by clearing
     a cheque or arranging for the clearing of a cheque); or
 
          (iii) otherwise acts for another person in arranging to collect or
     secure payment of dividends for such a person;
 
that person (the "collecting agent") is liable to account for U.K. income tax at
the lower rate (currently 20 per cent.) on such dividends, less any U.S. tax
withheld from the dividends to the extent that it does not exceed 15 per cent.
of the dividends. The collecting agent is entitled to deduct a corresponding
amount from the dividend. Certain exemptions from such liability may be
applicable, including, for example, where:
 
          (i) the Network Associates Common Stock is held in a recognised
     clearing system and either the collecting agent is acting as a depositary
     for that clearing system (Euroclear, Cedel, Depository Trust Company and
     First Chicago Clearing Center are recognised clearing systems for this
     purpose) or the collecting agent either pays or accounts for the dividends
     directly or indirectly to the recognised clearing system and the collecting
     agent has obtained a declaration in a form required by law from the
     recognised clearing system or its depositary; or
 
          (ii) the person beneficially entitled to the dividends and who
     beneficially owns the Network Associates Common Stock is either not
     resident in the U.K. or is specified by regulations; or
 
          (iii) the dividends arise to trustees not resident in the U.K. of
     certain discretionary or accumulation trusts (where, inter alia, none of
     the beneficiaries of the trust is resident in the U.K.); or
 
          (iv) the person beneficially entitled to the dividends is eligible for
     certain relief from tax in respect of the dividends (for example, charities
     or pension funds).
 
     In the case of each of the above exceptions (i) to (iv), conditions imposed
by regulations may have to be satisfied for the relevant exception to be
available. Where income tax is deducted it will be paid to the U.K. Inland
Revenue. The tax deducted will be credited against the shareholder's liability
to U.K. income or corporation tax; in appropriate cases, a shareholder will be
liable to a higher rate of income tax in addition to the tax deducted, or will
be entitled to a refund where the amount deducted exceeds his liability to U.K.
taxation.

     Stamp Duty and Stamp Duty Reserve Tax.  No U.K. stamp duty will be payable
in connection with a transfer of Network Associates Common Stock (or interests
therein) executed outside the U.K. unless it relates to something done or to be
done in the U.K.
 
     No U.K. stamp duty reserve tax will be payable in respect of an agreement
to transfer interests in Network Associates Common Stock (unless it is
registered in a register kept in the U.K. by or on behalf of Network
Associates).
 
     EACH HOLDER OF DR SOLOMON'S ORDINARY SHARES OR DR SOLOMON'S ADSS IS URGED
TO CONSULT HIS OR HER OWN TAX ADVISER AS TO THE U.S. FEDERAL INCOME AND U.K. TAX
CONSEQUENCES OF THE ACQUISITION BY HIM OR HER, AND ALSO AS TO ANY STATE, LOCAL,
FOREIGN OR OTHER TAX CONSEQUENCES.
 
     IF YOU ARE IN ANY DOUBT ABOUT YOUR OWN TAX POSITION, YOU SHOULD CONSULT
YOUR PROFESSIONAL ADVISER.
 
12. DR SOLOMON'S SHARE OPTIONS
 
(A) THE 1996 SCHEMES
 
     Options granted under the 1996 Schemes will become exercisable for a period
of six months commencing on the date optionholders are formally notified about
the Scheme. Any exercise during this period will be conditional on the Scheme
becoming effective. On the expiry of that period, any unexercised options will
lapse.
 
     As alternatives to exercise, holders of options under the 1996 Schemes will
have the opportunity to either:
 
          (i) cancel their options over Dr Solomon's Ordinary Shares in return
     for shares of Network Associates Common Stock on the following basis:
 
             An option holder will receive such number of shares of Network
        Associates Common Stock as is of a value equal to the number of Dr
        Solomon's Ordinary Shares under the cancelled option multiplied by
        0.27625 of a share of Network Associates Common Stock less the aggregate
        exercise price of the option, rounded down to the nearest whole number
        of shares of Network Associates Common Stock. For these purposes, the
        value of a share of Network Associates Common Stock will be the value
        attributed to it by the terms of the Scheme. Entitlements to fractional
        shares of Network Associates Common Stock will be treated as set out in
        paragraph 2 above; or
 
          (ii) release their options over Dr Solomon's Ordinary Shares in
     consideration for the grant of options of an equivalent value over shares
     of Network Associates Common Stock. The basis of the release and grant of
     options will be by reference to the values attributed to Dr Solomon's
     Ordinary Shares and shares of Network Associates Common Stock by the terms
     of the Scheme. Inland Revenue approval will be sought for the terms of the
     release and grant of options under the Company Share Option Scheme 1996.
     The new options will be governed by the rules of the relevant 1996 Scheme.
 
     Details of all the arrangements referred to above, including any tax
consequences, will be sent to holders of options in due course.
 
     Following the Effective Date, no further options will be granted under the
1996 Schemes.
 
                                       25
<PAGE>   26
 
(B) THE GROUP SCHEME
 
     Options granted under the Group Scheme which are not already exercisable
will become exercisable for one month from the Effective Date. On the expiry of
that period, any unexercised options will lapse.
 
     As an alternative to exercise, holders of options under the Group Scheme
will have the opportunity to release their options over Dr Solomon's Ordinary
Shares in consideration for the grant of options of an equivalent value over
shares of Network Associates Common Stock. The basis of the release and grant of
options will be by reference to the values attributed to Dr Solomon's Ordinary
Shares and Network Associates Common Stock by the terms of the Scheme.
 
     No further options can be granted under the Group Scheme.
 
(C) DR SOLOMON'S SAVINGS RELATED SHARE OPTION SCHEME
 
     There are no subsisting options under the Dr Solomon's Savings Related
Share Option Scheme.
 
(D) GENERAL
 
     It is proposed to amend the Articles of Association of Dr Solomon's at the
Extraordinary General Meeting to provide that if the Scheme becomes effective,
any Dr Solomon's Ordinary Shares allotted and issued or transferred (other than
to Network Associates) after the Record Date must automatically be transferred
to Network Associates on the same terms as under the Scheme.
 
     The effect of this amendment and the rules of the 1996 Schemes on the
exercise of options granted under the 1996 Schemes will be that exercising
option holders receive Network Associates' Common Stock (and cash for any
fractional entitlements) rather than Dr Solomon's Ordinary Shares, on the same
terms as under the Scheme.
 
Exercise of options granted under the Group Scheme are satisfied by the transfer
of Dr Solomon's Ordinary Shares from the Dr Solomon's Trust. As the Scheme will
extend to the Dr Solomon's Ordinary Shares held in the Dr Solomon's Trust, the
trustee of the Dr Solomon's Trust (the "Trustee") will continue to satisfy the
exercise of options under the Group Scheme from the Effective Date by
transferring new Network Associates Common Stock (and delivering cash in lieu of
any fractional entitlements) on the same basis as under the Scheme. Holders of
options granted under the Group Scheme who exercise their options during the one
month period from the Effective Date will still be entitled to have Dr Solomon's
Ordinary Shares transferred to them, in the first instance, but those shares
would automatically have to be transferred to Network Associates by virtue of
the amendment to the Articles of Association of Dr Solomon's in exchange for
Network Associates' Common Stock (and cash in lieu of any fractional
entitlements) on the same basis as under the Scheme. To give effect to the
exchange, the Trustee has agreed (pursuant to an agreement entered into between
Dr Solomon's, Network Associates and the Trustee referred to in paragraph 3(h)
of Appendix 8 of this document) to deliver to such holders of options new
Network Associates' Common Stock (and cash in lieu of any fractional
entitlements) on the same basis as under the Scheme.
 
     Details of options held by directors of Dr Solomon's under the Dr Solomon's
Share Option Schemes are set out in paragraph 2(a)(i) of Appendix 11.

13. MEETINGS
 
     The Meetings will be held at the offices of Shandwick Consultants Limited,
Aldermary House, 10-15 Queen Street, London EC4N 1TX on 21 July 1998. The Court
Meeting will commence at 11.00 a.m. (London time). The Extraordinary General
Meeting will commence at 11.15 a.m. (London time) or as soon thereafter as the
Court Meeting has concluded or been adjourned.
 
  Court Meeting
 
     Set out on page 183 of this document is a notice of a meeting of the
holders of Dr Solomon's Ordinary Shares which has been convened by the direction
of the Court for the purpose of considering and, if thought fit, approving the
Scheme. At this meeting, voting will be by way of a poll and holders of Dr
Solomon's Ordinary Shares will be entitled to one vote for each Dr Solomon's
Ordinary Share held. The resolution will be passed if a majority in number
representing not less than 75 per cent. in nominal value of Dr Solomon's
Ordinary Shares represented by those present and voting, either in person or by
proxy, votes in favour of the Scheme. In the case of joint holders, the vote of
the senior who tenders a vote, whether in person or by proxy, will be accepted
to the exclusion of the vote(s) of the other holder(s) and, for this purpose,
seniority will be determined by the order in which the names stand in the
Register of Members of Dr Solomon's.
 
  Extraordinary General Meeting
 
     In addition, an Extraordinary General Meeting of Dr Solomon's, notice of
which is set out on pages 184 to 186 of this document, has been convened for the
purpose of passing the special resolution necessary to enable effect to be given
to the Acquisition, including approving the Transaction Agreement and amending
the Articles of Association of Dr Solomon's. The special resolution will be
passed if approved by a majority of not less than three-fourths of the votes
cast.
 
  Holders of Dr Solomon's ADSs
 
     Holders of Dr Solomon's ADSs of record at 5:30 p.m. (New York City time) on
23 June 1998 will be entitled by means of the WHITE Letter of Instruction to
instruct the Depositary how to vote the Dr Solomon's Ordinary Shares underlying
their Dr Solomon's ADSs at the Court Meeting and the Extraordinary General
Meeting. In addition, the Board of Dr Solomon's has decided that any Dr
Solomon's ADS holders wishing to attend either of the Meetings as
non-participating observers are invited to do so but they may not vote at either
of the Meetings.
 
     Holders of Dr Solomon's ADSs who wish to vote in person at the Meetings
must, on or before 23 June 1998 and in accordance with the Deposit Agreement,
become registered holders of Dr Solomon's Ordinary Shares by arranging for the
surrender of their Dr Solomon's ADRs to the Depositary.
 
     In relation to the Meetings, Network Associates has undertaken not to
instruct the Depositary to vote in respect of any Dr Solomon's ADSs which may be
held by it.
 
14. SETTLEMENT AND DEALINGS
 
     Certificates for new Network Associates Common Stock, together with cheques
in respect of any fractional entitlements, are expected to be despatched to
former holders of Dr Solomon's Ordinary Shares no later than five Business Days
after the Effective Date. In the case of joint holders, these will be despatched
to the joint holder whose name appears first in the register. All documents and
cheques will be sent by pre-paid post at the risk of the person entitled
thereto.
 
                                       27
<PAGE>   28
 
     As from the Effective Date, Dr Solomon's ADSs will cease to be listed on
both the NASDAQ and the EASDAQ stock exchanges. Existing share certificates
representing Dr Solomon's Ordinary Shares will cease to be of value and
shareholders will be bound on the request of Dr Solomon's to return such
certificates for cancellation.
 
     After the Effective Date, the Depositary will send each holder of Dr
Solomon's ADSs a notice that the Deposit Agreement will terminate after 90 days
of such notice and instructing each such holder to surrender the Dr Solomon's
ADRs evidencing his Dr Solomon's ADSs to the Transfer Agent in exchange for the
transfer of shares of new Network Associates Common Stock. Upon receipt of such
Dr Solomon's ADRs, together with a properly executed Letter of Transmittal, the
Transfer Agent will arrange for the transfer of 0.82875 shares of new Network
Associates Common Stock for each Dr Solomon's ADS, together with a cheque in
respect of any fractional entitlements. Holders of Dr Solomon's ADSs will not be
charged any fees upon such surrender and exchange of Dr Solomon's ADSs for
shares of Network Associates Common Stock. Any such fees will be shared equally
by Network Associates and Dr Solomon's. After the Effective Date, each Dr
Solomon's ADR evidencing Dr Solomon's ADSs will represent only the right to
receive the appropriate numbers of shares of new Network Associates Common Stock
in exchange therefor.
 
     Dealings in shares of new Network Associates Common Stock on NASDAQ are
expected to begin at the commencement of trading (New York City time) on the
Effective Date.
 
     Mandates in force at the Effective Date relating to the payment of
dividends and other instructions given to Dr Solomon's by holders of Dr
Solomon's Shares will, unless specifically revoked or amended, be deemed as from
the Effective Date to relate to corresponding holdings of new Network Associates
Common Stock.
 
15. ACTION TO BE TAKEN
 
     IN ORDER THAT THE COURT CAN BE SATISFIED THAT THE VOTES CAST AT THE COURT
MEETING CONSTITUTE A FAIR REPRESENTATION OF THE VIEWS OF HOLDERS OF DR SOLOMON'S
ORDINARY SHARES, IT IS IMPORTANT THAT AS MANY VOTES AS POSSIBLE ARE CAST (EITHER
IN PERSON OR BY PROXY) AT THE COURT MEETING.
 
HOLDERS OF DR SOLOMON'S ORDINARY SHARES

          2. by either Dr Solomon's or Network Associates:
 
             (i) if the Required Shareholders Vote shall not have been obtained
        at the duly held Dr Solomon's shareholder meetings or any adjournments
        thereof;
 
             (ii) if any Governmental Entity shall have issued an order, decree
        or ruling or taken any other action permanently enjoining, restraining
        or otherwise prohibiting the Acquisition and such order, decree, ruling
        or other action shall have become final and nonappealable;
 
             (iii) in the event of a breach by the other party of any
        representation, warranty, covenant or other agreement contained in the

             (iv) if the Effective Date shall not have occurred by 31 October
        1998, for any reason; provided, however, that the right to terminate the
        Transaction Agreement shall not be available to any party whose action
        or failure to act has been a principal cause of or resulted in the
        failure of the Effective Date to occur on or before such date and such
        action or failure to act constitutes a breach of the Transaction
        Agreement.
 
          3. by Dr Solomon's: if the Board of Dr Solomon's approves or
     recommends a bona fide proposal to acquire, directly or indirectly, for
     consideration consisting of cash and/or securities, more than 50 per cent.

     substantially all the assets of Dr Solomon's, and otherwise on terms which
     the Board of Dr Solomon's determines in its good faith reasonable judgement
     to be more favourable to Dr Solomon's stockholders than the Acquisition
     (after having received the advice of Dr Solomon's independent financial
     adviser as to the value of the consideration provided for in such proposal)
     and for which financing, to the extent required, is then committed or
     which, in the good faith reasonable judgment of the Dr Solomon's Board, is
     reasonably capable of being financed by such third party (a "Dr Solomon's
     Superior Proposal") and Dr Solomon's shall have paid to Network Associates
     the break up fee referred to below under the heading "Payment on
     Termination";

        proposal for a merger or other business combination, any scheme of
        arrangement, exchange offer, liquidation, or takeover offer (within the
        meaning of Section 428 of the Companies Act) involving Dr Solomon's or
        any of its subsidiaries or any proposal or offer to acquire in any
        manner, directly or indirectly, an equity interest of 15 per cent. or
        more in any voting securities of or a substantial portion of the assets
        of Dr Solomon's or any of its subsidiaries, or any other similar
        transactions the consummation of which could reasonably be expected to
        prevent or materially impede, interfere with, or delay the Acquisition
        (a "Dr Solomon's Acquisition Proposal") is commenced, publicly proposed,
        publicly disclosed or communicated to Dr Solomon's (or the willingness
        of any person to make a Dr Solomon's Acquisition Proposal is publicly
        disclosed or communicated to Dr Solomon's) and the Board of Dr Solomon's
        or any committee thereof shall have withdrawn or modified in a manner
        adverse to Network Associates its approval or recommendation for the
        Required Shareholders Vote, and approved or recommended the Dr Solomon's
        Acquisition Proposal, or resolved to do the foregoing actions;
 
             (ii) if Dr Solomon's shall have entered into any agreement with
        respect to any Dr Solomon's Superior Proposal; or
 
             (iii) if the Effective Date shall not have occurred on or prior to
        31 August 1998 other than as a result of a material breach of the
        Transaction Agreement by Network Associates or as a result of the
        failure to satisfy the U.S. HSR anti-trust condition in paragraph 3
        above (set out in the conditions to be satisfied or waived prior to the
        Final Hearing) prior to such date (unless such failure shall be the
        result of a material breach by Dr Solomon's of its obligations contained
        in the Transaction Agreement).
 
PAYMENT ON TERMINATION
 
     1. Dr Solomon's shall promptly pay, or cause to be paid, to Network

     Network Associates in the circumstances set out in (4)(iii) above under the
     heading "Termination of the Transaction Agreement" (provided that Network
     Associates is not in material breach of the Transaction Agreement and at

                          INFORMATION ON DR SOLOMON'S
 
A. DESCRIPTION OF BUSINESS OF DR SOLOMON'S
 
DR SOLOMON'S ANTI-VIRUS TOOLKIT
 
     Dr Solomon's Anti-Virus Toolkit is a family of anti-virus software programs
that detect, identify and eradicate a wide variety of computer viruses, while
minimising false alarms, maximising speed of operation and minimising
obtrusiveness in use of system resources. The Toolkit virus scanners are
available for most PC operating system platforms, including DOS, OS/2, Windows
3.x, Windows 95, Windows NT, NetWare, Apple Macintosh and SCO UNIX. Over the
last year, Dr Solomon's has also developed virus scanners specifically
addressing virus problems in e-mail (MailGuard), Lotus Domino and Microsoft
Exchange.
 
     Toolkit programs are available for use both by individual PC users and by
corporate customers on either servers or workstations. Each program in the
Toolkit can be licensed individually. The Toolkit comprises the following main
programs:
 
     - FINDVIRUS(TM) is an on-demand scanner that searches a computer's memory,
       boot sector, partition tables, files and disks for particular pieces of
       foreign computer code that are known to be viruses. Using Dr Solomon's
       Generic Decryption Engine(TM) and Advanced Heuristic Analyzer(TM),
       FindVirus searches for known and new viruses, including complex encrypted
       and polymorphic viruses. The most recent version of FindVirus can detect
       and identify more than 19,000 known viruses and, using heuristics, an
       estimated 80 per cent. of unknown viruses. FindVirus scans recursively
       inside compressed and archived files, supporting versions of the most
       widely used compression formats, including PKZip, ARJ, ARC, ICE, PKLite,
       LZExe, LZH, DIET and CryptCom. FindVirus can also repair, overwrite and
       delete infected files and generate reports of its findings. Using the
       Toolkit's scheduling facility, users can program FindVirus to execute
       periodically without user intervention. FindVirus is available in 32-bit
       or 16-bit code.
 
     - VIRUSGUARD(TM) is a terminate-and-stay-resident program for DOS-based
       personal computers that provides constant background virus protection.
       After scanning a computer system's memory, boot sector, partition tables
       and system files for known and unknown viruses, VirusGuard becomes
       resident in the system's memory and monitors all program load and file
       open requests, checking files as they are copied or executed ("on-access"
       scanning), including files being downloaded from the Internet or online
       bulletin boards. VirusGuard requires only 9 Kbytes of memory, minimising
       its use of scarce system resources and its impact on a user's operations.
 
     - WINGUARD(TM) offers similar functionality to VirusGuard for PCs using the
       Windows 3.x or Windows 95 operating systems and operates using virtual
       device driver technology. Dr Solomon's also offers similar programs for
       other operating systems platforms, including WinGuard for Windows NT,
       File Access Monitor in the Toolkit for NetWare, and MacGuard(TM) for the
       Apple Macintosh.
 
     - VIVERIFY(TM) is a checksummer that detects changes in executable files
       that may have been caused by viruses.
 
     The Toolkit virus scanning drivers are updated monthly to provide for the
detection and eradication of recently discovered viruses. Toolkit customers are
provided with monthly or quarterly update disks, either directly from Dr
Solomon's or from Dr Solomon's distributors and resellers. Dr Solomon's
currently provides updates electronically to retail product users in the United
States and is currently testing software to extend this capability to corporate
users in its major geographical markets.
 
                                       39
<PAGE>   40
 
     The Toolkit is available in seven European languages and variations of some
of the Toolkit programs are available in Japanese. The Toolkit comes complete
with both on-line and paperback versions of Dr Solomon's Virus Encyclopaedia,
which describes in detail hundreds of viruses. New versions of the Toolkit
programs are released on a regular basis to provide new features and product
enhancements.
 
     The Toolkit programs may be licensed for periods of one, two or three
years, with a choice of receiving updates either on CD or on disk on a quarterly
or monthly basis. License fees are based upon the number of users and servers
and are generally paid in full upon the execution of each license. Updates and
technical support are offered over the term of each license at no additional
charge to the initial license fee.
 
     Dr Solomon's also sells "boxed product" versions of the Toolkit, both for
single-users and as boxed licenses. Purchasers of boxed-products can elect to
receive monthly or quarterly updates and have access to technical support
personnel.
 
     In 1997 Dr Solomon's introduced versions of its products aimed specifically
at the single user for purchase through retail outlets. HomeGuard(TM) is sold in
the United Kingdom, and in certain other international markets. In the United
States, Dr Solomon's Anti-Virus was introduced in March 1997 and a Deluxe
version has recently been launched.
 
     In October 1997 Dr Solomon's acquired the rights to the Virex(TM) product,
the technology leader in Macintosh virus protection, incorporating patented
Speedscan and Scan-at-Download technology.
 
RESEARCH AND PRODUCT DEVELOPMENT
 
     Since its inception, Dr Solomon's has made substantial investments in
research and product development. Dr Solomon's research and product development
efforts are focused on (i) updating its products to respond to the development
and proliferation of new computer viruses, (ii) updating its products to respond
to changes in operating systems platforms, (iii) improving the performance of
its products and developing new product features and enhancements and (iv)
developing new products.
 
     To respond to the discovery of new viruses, Dr Solomon's releases new
versions of its anti-virus software programs on a monthly basis. Some types of
new viruses can be accommodated simply by including the "signature" or
"fingerprint" of the new virus within the Toolkit's virus scanning drivers,
while other types of new viruses require the development of new methods to
search for the virus. The latter process requires Dr Solomon's to modify all the
virus scanning and repair programs in the various versions of the Toolkit, test
them, master the CD and disk sets and conduct final quality control testing of
the master disks prior to duplication of customer update disks and CDs.
 
     Dr Solomon's also frequently updates its products to respond to changes in
operating system platforms. Since anti-virus software products interact with
operating systems at a very low level, Dr Solomon's must carefully monitor
changes to operating system platforms and respond quickly to such changes. Many
viruses operate at the very heart of computer operating systems and invoke very
low-level controls of computer hardware components. In order to combat viruses,
anti-virus technologists must similarly function at very low levels. Such
specialised expertise differs from that required to write typical PC application
programs.
 
                                       40
<PAGE>   41
 
     Some recent developments in the products include:-
 
  Trojan Horse detection and repair
 
     FindVirus now detects and disinfects more than 500 Trojan Horse programs.
These programs can steal passwords, screen names and other personal information
from online users.
 
  Management Edition
 
     The installation and management of anti-virus software across networks has
been improved by Dr Solomon's introduction of Management Edition. The latest
version allows management of Windows 3.x, Windows 95 and NT computers and
NetWare servers.
 
OTHER PRODUCTS AND SERVICES
 
     During the course of its development, Dr Solomon's has been involved in
various sectors of the PC security market. In recent years, it has focused more
closely on its anti-virus products and services. The other products and
services, some of which are complementary to the anti-virus products,
represented less than 5 per cent. of Dr Solomon's revenue for the year ended 31
May 1997. Dr Solomon's believes that increased profitability can be achieved
through growth in sales of the Audit, netOctopus and Support Software products.
Dr Solomon's will continue to investigate new product opportunities.
 
  Audit
 
     Dr Solomon's Audit is a software and hardware management system that
permits system administrators to monitor software packages installed on
individual PCs, and the hardware configuration of those PCs, throughout an
organisation, thereby recording where hardware is installed and helping systems
administrators ensure that software is correctly and efficiently licensed.
Audit's Software Package Library(TM), which is updated quarterly, enables Audit
to identify many common software packages and is customisable by users. Audit is
marketed in Europe and Chile. The rights for Audit were acquired from
Performance Publishing Limited in November 1997, Dr Solomon's having previously
marketed the product under exclusive license.
 
  Support Software
 
     Dr Solomon's Support Software is an automated helpdesk system that enables
a customer's support staff to log and track telephone enquiries more
effectively. Support Software permits users to store and retrieve solutions to
frequently asked questions and to generate flexible reports on service
department operations. Users can customise Support Software to particular
applications in various industries.
 
  netOctopus
 
     Dr Solomon's netOctopus is a network and system administration solution for
Apple Macintosh. It enables administrators to install, configure and update a
wide variety of software and to conduct both hardware and software audits on
Apple Macintosh computers from a central desktop.
 
  Consultancy Services and Seminars
 
     Dr Solomon's assists certain corporate customers in installing and updating
their anti-virus products and in formulating and implementing general security
and anti-virus strategies plus dealing with virus outbreaks. Dr Solomon's also
sponsors a Live Virus Workshop, which gives users hands-on experience in dealing
with virus outbreaks.

CUSTOMERS
 
     Dr Solomon's sales and marketing efforts are targeted primarily at medium
and large corporate customers, although Dr Solomon's also sells and markets its
products to small businesses and individual PC users. Dr Solomon's currently
licenses the Toolkit to more than 100,000 customers across all sectors of
business.
 
EMPLOYEES
 
     As at 30 April 1998, Dr Solomon's had 550 employees, of whom 374 were
located in Aylesbury, Buckinghamshire, England, 110 were located in Burlington,
Massachusetts and in Raleigh, North Carolina, 58 were located in Hamburg and
Munich, Germany and 8 were located in Melbourne and Sydney, Australia. As at
that date, 184 of Dr Solomon's employees were engaged in sales and marketing
activities, 134 in product development and testing, 105 in technical support, 50
in operations and 77 in administration, management information systems and
finance.
 
     Dr Solomon's employees are not party to any collective bargaining
agreements and Dr Solomon's believes that its relations with its employees are
generally good. Most of Dr Solomon's employees are participants in one or more
of Dr Solomon's Share Option Schemes and many of Dr Solomon's managers, sales
staff and software developers are eligible to receive bonuses under performance
bonus schemes. Dr Solomon's believes that its future success will depend in part
upon its ability to continue to attract, retain and motivate qualified
technical, sales and managerial personnel. Although the competition for such
personnel in the software industry is intense, the geographic location of the
main development team in Aylesbury mitigates the risk of direct competition for
such staff.

B. FINANCIAL INFORMATION ON DR SOLOMON'S
 
NATURE OF THE FINANCIAL INFORMATION
 
     The financial information contained in this Part B, and in Part B of
Appendix 4 of this document, does not constitute statutory accounts within the
meaning of Section 240 of the Companies Act.
 
     Such financial information relating to S&S International (the former
holding company of Dr Solomon's businesses) for the two financial years ended 31
May 1995 has been extracted without audit from the published reports and audited
consolidated financial statements of S&S International for the two financial
years ended 31 May 1995. The financial information relating to S&S International
for the period 1 June 1995 to 6 February 1996 (the date of the management
buyout) and the financial information relating to Dr Solomon's for the period 7
February 1996 to 31 May 1996 and the financial year ended 31 May 1997 has been
extracted without audit from the published reports and audited consolidated
financial statements of S&S International and Dr Solomon's respectively for such
periods. S&S International's auditors and Dr Solomon's auditors, respectively,
have made a report under Section 235 of the Companies Act 1985 on the financial
statements for the two periods ended 31 May 1995 and the period 1 June 1995 to 6
February 1996 (in respect of S&S International) and 7 February 1996 to 31 May
1996 and the financial year ended 31 May 1997 (in respect of Dr Solomon's) and
statutory accounts have been delivered to the Registrar in respect of each of
those periods. Each such report was unqualified and did not contain a statement
under Section 237(2) to (4) of the Companies Act 1985.
 
     Such financial information relating to Dr Solomon's for the three quarterly
periods ended 31 August 1997, 30 November 1997 and 28 February 1998 has been
extracted without audit from Dr Solomon's filings with the Commission on Forms
6-K for those periods.
 
BASIS OF PRESENTATION
 
     The consolidated financial statements have been prepared in accordance with
U.K. GAAP, which differs in certain significant respects from U.S. GAAP. See
Note 22 to the audited consolidated financial statements. The consolidated
financial statements include the accounts of Dr Solomon's and its wholly owned
subsidiaries. All significant intercompany accounts and transactions have been
eliminated. In the opinion of management, all adjustments, consisting only of
normal recurring adjustments considered necessary for a fair presentation, have
been included. The results of operations for the nine months ended 28 February
1998 are not necessarily indicative of the results to be expected for the full
year or for any future periods. The accompanying consolidated financial
statements should be read in conjunction with the audited consolidated financial
statements contained in Dr Solomon's Annual Report on Form 20-F for the year

             NOTES TO THE AUDITED CONSOLIDATED FINANCIAL STATEMENTS
 
 1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  BASIS OF CONSOLIDATED FINANCIAL STATEMENTS
 
     The consolidated financial statements are prepared in conformity with
generally accepted accounting principles in the United Kingdom ("U.K. GAAP").
 
     References to "Company" throughout the consolidated financial statements
are to Dr Solomon's Group PLC and its subsidiaries. References to "S&S
International" are to its predecessors S&S International Limited, and its
subsidiaries.
 
  BUSINESS
 
     The Company develops, markets and supports anti-virus software programs for
personal computers and PC networks. The Company's products provide effective and
easy to use software solutions to the risks posed by the proliferation of new
and increasingly sophisticated types of computer viruses. The Company's
principal product line is the "Dr Solomon's Anti-Virus Toolkit" family of
software programs (the "Toolkit").
 
  CONSOLIDATION AND GOODWILL
 
     The consolidated financial statements include the accounts of both the
Company and S&S International for the periods specified. The difference between
consideration payable for the acquisition of interests in subsidiary companies
and the fair value of the assets acquired is written off directly to reserves in
the year of acquisition.
 
  ACCOUNTING CONVENTION
 
     The financial statements are prepared under the historical cost convention.
 
  FIXED ASSETS
 
     The cost of acquired fixed assets includes the purchase cost, together with
any incidental expenses of acquisition. The cost of purchased software is
capitalized and amortized from the implementation date over its estimated useful
economic life. The cost of software developed for internal use is expensed in
the period in which the cost is incurred.
 
     Depreciation of fixed assets is provided on a straight line basis over the
estimated useful lives of the respective assets, as follows:
 
<TABLE>
<S>                               <C>
Short leasehold property and      Over the remaining term of the lease
improvements
Motor vehicles                    Over 4 years
Fixtures, fittings and equipment  Between 2 and 5 years
Software                          Between 2 and 3 years
</TABLE>
 
  DEFERRED TAXATION
 
     Deferred taxation is provided on timing differences, arising from the
different treatment of items for accounts and taxation purposes, which are
expected to reverse in the future, calculated at rates at which it is estimated
that tax will arise.

       NOTES TO THE AUDITED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  FOREIGN EXCHANGE
 
     Profit and loss accounts in foreign currencies are translated into sterling
at the average rates of exchange prevailing for the relevant financial period.
Monetary assets and liabilities denominated in foreign currencies at the period
end are translated into sterling at the rate prevailing at the balance sheet
date. These differences are dealt with in the profit and loss account. Exchange
differences arising on the translation of the net investment in foreign
subsidiaries are dealt with as adjustments to reserves.
 
  ACCOUNTING ESTIMATES
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the date
of the consolidated financial statements and the reported amounts of revenues
and expenses during the reported period. Accounting estimates have been employed
in these consolidated financial statements to determine reported amounts,
including realizability of debtors and other assets and the useful lives of
fixed assets. Actual results could differ from those estimated.
 
  REVENUE RECOGNITION
 
     The Company recognizes revenues from product licenses and update services
(both of which include post-contract support) on a straight-line basis over the
term of the contracted service (usually one, two or three years in the case of
product licenses and one year in the case of update services).
 
     The Company recognizes 50 per cent. of the revenues from the sale of boxed
products which include an update service at the time of sale and the remaining
50 per cent. evenly over the term of the update service (including post-contract
support) included in a sale (normally one year). For those boxed products not
including an update service, revenue is recognised at time of sale.
 
  RESEARCH AND DEVELOPMENT AND SOFTWARE DEVELOPMENT COSTS
 
     Research and development expenditure and software development costs are
charged to the profit and loss account as incurred. Based on the Company's
product development process, technological feasibility is established upon
completion of a working model. Subsequent costs to the point at which the
product is ready for general release have not been significant and none of these
costs have been capitalized.
 
  EARNINGS PER SHARE
 
     Earnings per share have not been computed for periods which relate to S&S
International, as such information is not considered meaningful for a period
over period comparison due to the different capital structure of S&S
International as compared to the Company.
 
     Earnings per share are based upon the weighted average number of ordinary
shares in issue throughout the period and are calculated on the profit on
ordinary activities, after taxation and after other finance charges in respect
of non-equity shares, but before equity dividends.
 
2. ANALYSIS OF TURNOVER, OPERATING PROFIT/(LOSS) AND NET ASSETS/(LIABILITIES)
 
     Turnover represents amounts derived from product licenses, sales of
boxed-products and providing updates to boxed-products, and royalty income.

     The high rates of effective taxation are due primarily to the losses
     incurred in the US which could not be offset against U.K. profits for
     taxation purposes and to the accelerated depreciation policy relating to
     fixed assets compared to allowances for taxation purposes, for which no
     deferred tax asset is recognised in accordance with U.K. GAAP.
 
     There are no deferred tax liabilities, provided or unprovided at 31 May
1997.

22. SUMMARY OF DIFFERENCES BETWEEN GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
     IN THE UNITED KINGDOM AND THE UNITED STATES
 
     The Consolidated Financial Statements are prepared in accordance with
generally accepted accounting principles in the United Kingdom ("U.K. GAAP"),
which differ in certain significant respects from those generally accepted in
the United States ("US GAAP"). The differences that are significant to Dr
Solomon's Group PLC relate to the following items:
 
  GOODWILL AND INTANGIBLE ASSETS
 
     Under U.K. GAAP, costs of acquisitions in excess of the fair value of the
attributable net assets of acquired businesses at the date of acquisition may be
capitalised or may be written off against shareholders' equity, either in the
financial year of acquisition or in a subsequent financial year. Dr Solomon's
Group PLC has written off such goodwill against shareholders' equity in the
financial year of acquisition.
 
     Under US GAAP, the excess of the purchase price over the net assets
acquired is allocated to goodwill and other intangible assets based on the
requirements of Accounting Principles Board Opinion No.16 "Business
Combinations" (APB 16). The assets are capitalized and then amortized over a
term not to exceed 40 years.
 
  DEFERRED TAXATION
 
     Under U.K. GAAP, deferred taxation is provided at the same rates at which
the taxation is expected to become payable. No provision is made for amounts
which are not expected to become payable in the foreseeable future and no
account is taken of deferred tax assets in accordance with Statement of Standard
Accounting Practice 15.
 
     Under US GAAP, deferred taxation is provided on all temporary differences
under the liability method at rates which the taxation would be payable in the
relevant future year as prescribed by Statement of Financial Accounting Standard
("SFAS") No. 109 - "Accounting for Income Taxes".
 
  DIVIDENDS
 
     Under U.K. GAAP dividends are included in the financial statements when
recommended by the Board of Directors to the shareholders.
 
     Under US GAAP, dividends are not included in the financial statements until
declared by the Board of Directors.

       NOTES TO THE AUDITED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  EARNINGS PER SHARE
 
     Under U.K. GAAP earnings per share are based on the weighted average number
of ordinary shares in issue throughout the period and are calculated on the
profit on ordinary activities after taxation and after other finance charges in
respect of non-equity shares, but before equity dividends.
 
     Under US GAAP income per share is based on the weighted average number of
ordinary shares in issue throughout the period and is calculated on the net
income for the period.
 
  CASH AND CASH EQUIVALENTS
 
     Under U.K. GAAP, cash is defined as cash in hand and deposits repayable on
demand, less overdrafts repayable on demand. Cash equivalents are no longer
defined. Deposits are classified as liquid investments.
 
     Under US GAAP, cash equivalents consist of all deposits with an original
maturity of three months or less. Cash is not stated net of overdrafts, instead
these are presented within the financing section of the cash flow statement.
 
  COMPENSATION EXPENSE
 
     Under US GAAP, the Company follows the provisions of Accounting Principles
Board Opinion no. 25, "Accounting for stock issued to employees" and is required
to recognize a non-cash compensation expense equal to the difference between the
exercise price of options granted under the Dr Solomon's Group Share Option
Scheme and the fair market value of the options at the time they were granted.
This amounted to L17.808 million in the quarter ended 30 November 1996. Under US
GAAP, the Company is also required to recognize a non-cash compensation expense
of L2.0 million on the transfer of Investor Loan Stock to the executive
directors in the first quarter of the 1997 financial year.
 
  CONSOLIDATED STATEMENT OF CASH FLOWS
 
     The Consolidated Statement of Cash Flows prepared under U.K. GAAP differs
in certain presentational respects from the format required under SFAS
95 -- "Statement of Cash Flows". Under U.K. GAAP, a reconciliation of profits
from operations to cash flows from operating activities is presented in a note,
and cash paid for interest and income taxes is presented separately from cash
flows from operating activities. Under SFAS 95, cash flows from operating
activities are based on net profit, include interest and income taxes and are
presented on the face of the statement. U.K. GAAP requires cash to be presented
net of overdrafts; SFAS 95 treats overdrafts within financing activities.

     For the period 7 February 1996 until 31 May 1997 a tax charge has arisen on
the loss for the periods due mainly to the non-deductibility for US tax purposes
of the amortisation of goodwill and intangible assets.
 
     Deferred income tax assets are attributable to the following:

A. DESCRIPTION OF BUSINESS OF NETWORK ASSOCIATES
 
OVERVIEW
 
     Network Associates is a leading developer and provider of network security
and management software products. Network Associates has historically derived a
significant majority of its revenues from the licensing of its flagship McAfee
anti-virus products and Sniffer network fault and performance management
products. Network Associates 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, Network Associates recently organized its products
into four product suites -- McAfee Total Virus Defense and PGP Total Network
Security (together comprising "Net Tools Secure") and Sniffer Total Network
Visibility and McAfee Total Service Desk (together comprising "Net Tools
Manager"). These four product suites together form an integrated solution called
"Net Tools".
 
     Many of Network Associates' network security and management products,
including its industry-leading network security products for anti-virus
protection and Sniffer software-based fault and performance solutions for
managing computer networks, are also available as part of smaller product suites
or as stand-alone products. Network Associates is also a leader in electronic
software distribution, which is the principal means by which it markets its
products and one of the principal ways it distributes its software products to
its customers. Network Associates generally utilizes a two-year subscription
model for licensing its non-Sniffer products to corporate clients and is in the
process of developing a two-year subscription model for licensing its Sniffer
products as well.

NET TOOLS
 
     Net Tools is being designed as an integrated solution to protect the
enterprise from network security threats and to reduce the cost of managing an
enterprise network. While supporting other operating systems, Net Tools is being
optimized for Microsoft Windows NT technology ("NT"), employing an Explorer
Interface, Distributed OLE, ActiveX and the DCOM object model. Net Tools is
being designed to leverage NT to bridge the gap between the disparate network
management universes of NetWare and Unix servers. In addition, Net Tools is
being engineered to employ a common graphical user interface ("GUI"), together
with common reporting, alerting and scripting functionalities. Network
Associates is currently developing its pricing model for the licensing of its
Net Tools suite of products. Among other things, Network Associates is currently
developing a centralized console for its Net Tools product suite; developing its
pricing model for the Net Tools

certain PGP encryption products and TIS firewall products) into smaller suites
sold under the Net Tools umbrella.

     The Net Tools Secure product suite is comprised of McAfee Total Virus
Defense and PGP Total Network Security. A number of the products incorporated in
the Net Tools Secure product suite may be purchased as stand-alone products or
as part of smaller product suites.
 
     McAfee Total Virus Defense. McAfee Total Virus Defense ("McAfee TVD") is
designed to provide a single integrated defense against computer viruses at the
desktop, server and Internet gateway. McAfee TVD is comprised of three security
product suites: VirusScan Security Suite (providing multi-platform protection
for desktop clients); NetShield Security Suite (protects file, application and
groupware servers); and Internet Security Suite (locks out viruses and hostile
applets at the Internet gateway).
 
     PGP Total Network Security. PGP Total Network Security ("PGP TNS") is being
designed as an integrated suite of desktop and server solutions designed to
protect the digital assets of an enterprise through encryption and
authentication. All encryption algorithms used in PGP TNS provide "strong"
encryption with a minimum 128 bit key length for symmetric encryption, plus the
use of a public/private key scheme with larger keys. To Network Associates'
knowledge, no techniques currently exist that can "crack" these strong
encryption algorithms so they are usable even in demanding commercial and
military applications. PGP TNS is being designed as a comprehensive, scalable
security solution with central manageability and policy-based administration.
PGP TNS will comprise two network security product suites: the PGP Desktop Suite
(protects e-mails, files, disks and network communication); and the PGP Server
Suite (which is being developed to manage certificates, control encryption
policies and replicate certificate servers). Both PGP Desktop and Server suites
also include the PGPsdk which allows corporate or application developers to
create custom encryption using PGP's strong encryption algorithms. Complementing
PGP TNS is intrusion protection through the CyberCop product which is sold
separately and not as part of a suite and the Gauntlet firewall products
acquired by Network Associates' recent acquisition of TIS.
 
     The CyberCop intrusion detection system is designed to safeguard networks
from external and internal attacks by performing real-time surveillance of
network traffic and sending out an alarm when intrusion is detected. The
CyberCop product's sensors are placed at key locations throughout a network,
from LAN segments and dial-up modem servers to connection to the internet or
other wide area networks.
 
     The Gauntlet family of firewall products allow customers to create
"trusted" networks that are protected from access, theft and damage by
unauthorised users from "untrusted" networks such as the Internet and also
enable the creation of virtual private networks through the encrypted
transmission of information across untrusted networks.
 
NET TOOLS MANAGER: SNIFFER TOTAL NETWORK VISIBILITY AND MCAFEE TOTAL SERVICE
DESK
 
     Net Tools Manager is a network management and service desk solution
designed to make networks more efficient and network users more productive. The
Net Tools Manager product suite is comprised of Sniffer Total Network
Visibility, a comprehensive set of products and services for network fault and
performance management; and McAfee Total Service Desk, which integrates help
desk applications with desktop management software. McAfee Total Service Desk is
licensed on a two-year subscription basis. A number of the products incorporated
in the Net Tools Manager product suite may be purchased as part of smaller
product suites or as stand-alone products.
 
     Sniffer Total Network Visibility. Sniffer is one of Network Associates'
flagship products. Sniffer Total Network Visibility ("Sniffer TNV") offers
comprehensive network fault and performance
                                       66
<PAGE>   67
 
solutions to provide optimum network performance. Sniffer TNV is comprised of
three product suites: Sniffer Portable Analysis Suites which consist of portable
tools which analyze network traffic to pinpoint and help resolve performance
problems on a variety of multi-topology, multi-protocol networks; Sniffer
Distributed Analysis Suites which perform automatic network monitoring, protocol
decodes and problem analysis for identifying and resolving network problems from
a central single-fault and performance-management console; and Sniffer Service
Desk Suite which offers proactive management, reporting and service desk tools
for better supporting business objectives and delivering a higher quality of
service to end users.
 
     McAfee Total Service Desk. McAfee Total Service Desk ("McAfee TSD")
provides proactive network management and help desk technology in one integrated
service desk solution. McAfee TSD comprises three suites: (i) the McAfee
HelpDesk Suite which is designed to provide complete call management, problem
resolution, crisis management, change management and reporting for mid-range and
departmental help desks; (ii) the Zero Administration Client Suite which is
designed to provide enterprise wide control of network software with integrated
software distribution, software and hardware inventory, desktop
management/menuing, license metering and remote control features; and (iii) the
Self ServiceDesk Suite which is designed to provide information services
organizations with self service oriented applications designed to make all
supported PCs help desk ready.
 
TOTAL SERVICE SOLUTIONS
 
     As Network Associates' products and computer networks become more complex,
customers increasingly require greater professional assistance in the design,
installation, configuration and implementation of their networks and acquired
products. To meet these evolving customer needs, Network Associates has
established Total Service Solutions. Total Service Solutions is focused on three
services segments: Consulting Services, Total Education Service and Product
Support to complete the customer's product license relationship with Network
Associates.
 
     Consulting Services supports product integrations, customization and
deployment with an array of standardized and custom offerings. Consulting
Services also offers other services ranging from proactive and emergency
troubleshooting to network design, planning and simulation.
 
     Total Education Service offers an extensive curriculum of computer network
technology courses, from product training to advanced network troubleshooting
and performance management.
 
     Product Support technical representatives respond to customer calls and
electronic messages, resolve product issues and answer detailed questions.
 
CUSTOMERS
 
     Network Associates primarily markets its products directly to large
corporate and government customers as well as to resellers and distributors. No
customer accounted for more than 10 per cent. of Network Associates' net revenue
during the financial years ended 31 December 1997, 1996 or 1995.
 
EMPLOYEES
 
     As at 31 December 1997, Network Associates employed over 1,600 individuals
worldwide. Competition for qualified management and technical personnel is
intense in the software industry. Network Associates' continued success will
depend in part upon its ability to attract and retain qualified personnel. None
of Network Associates' employees is represented by a labor union and Network
Associates believes that its employee relations are good.

RECENT DEVELOPMENTS
 
  3-for-2 Common Stock Split
 
     On 29 May, 1998, Network Associates consummated the Network Associates
3-for-2 Stock Split by means of a stock dividend.
 
  Magic Solutions Acquisition
 
     On 1 April 1998 Network Associates acquired Magic Solutions, a privately
held provider of internal help desk and asset management solutions. In the
acquisition, a wholly owned subsidiary of Network Associates merged with and
into Magic Solutions; Magic Solutions became a wholly owned subsidiary of
Network Associates; and the existing Magic Solutions stock and option holders
received approximately $110,000,000 in cash. The Magic Solutions acquisition
broadened Network Associates' suite of service desk product offerings. The Magic
Solutions acquisition is accounted for as a purchase and Network Associates
currently expects that a substantial portion of this price will be expensed as
purchased in-process research and development in the quarter ended 30 June 1998.
 
  TIS Acquisition
 
     On 28 April 1998 Network Associates acquired 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 Network Associates merged with
and into TIS; TIS became a wholly owned subsidiary of Network Associates; each
outstanding share of TIS Common Stock converted into the right to receive 0.4845
of a share of Network Associates Common Stock (after giving effect to the
Network Associates' 3-for-2 Stock Split). The TIS acquisition broadened Network
Associates' suite of network security products. The TIS acquisition was
qualified as a pooling of interests for U.S. financial reporting purposes in
accordance with U.S. GAAP.
 
  Zero Coupon Debentures
 
     On 13 February 1998, Network Associates completed a private placement of
zero coupon convertible subordinated debentures due in 2018 (the "Debentures").
The Debentures, with an aggregate face amount at maturity of $885.5 million,
generated net proceeds to Network Associates of approximately $337.6 million
(after deducting the fee paid to the initial purchaser of the Debentures but no
other expenses of the placement). The initial price to the public for the
Debentures was $391.06 per $1,000 of face amount at maturity, which equates to a
yield to maturity over the term of the Debentures of 4.75 per cent. on a
semi-annual bond equivalent basis). The Debentures are convertible into Network
Associates Common Stock at the rate of 8.538 shares (after giving effect to the
Network Associates 3-for-2 Stock Split) per $1,000 of face amount at maturity,
which equates to an initial conversion price of $45.80 per share (after giving
effect to the Network Associates 3-for-2 Stock Split). The Debentures are
subordinated in right of payment to all existing and future senior indebtedness
and effectively subordinated in right of payment to all indebtedness and other
liabilities of Network Associates' subsidiaries. The Debentures may be redeemed
for cash at the option of Network Associates beginning on 13 February 2003. At
the option of the holder, Network Associates will purchase the Debentures as of
13 February 2003, 13 February 2008 and 13 February 2013 at purchase prices (to
be paid in cash or Network Associates Common Stock or any combination thereof,
at the election of Network Associates and subject to certain conditions) equal
to the initial issue price plus accrued original issue discount to such dates.
The Debentures may also be redeemed at the option of the holder if there is an
event that is deemed to constitute a "fundamental change" at a price equal to
the issue price plus accrued original issue discount to the date of redemption,
subject to adjustment.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION:
 
     The accompanying consolidated financial statements have been prepared by
Network Associates without audit. The consolidated financial statements include
the accounts of Network Associates and its wholly owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated. In the
opinion of management, all adjustments, consisting only of normal recurring
adjustments considered necessary for a fair presentation, have been included.
The results of operations for the three months ended 31 March 1998 are not
necessarily indicative of the results to be expected for the full year or for
any future periods. On 30 April 1998, Network Associates declared a 3-for-2
stock split effected through a stock dividend paid on 29 May 1998, as one share
of Network Associates Common Stock for every two shares of Network Associates
Common Stock outstanding. All per share data contained herein have been restated
to reflect the increased number of shares outstanding.
 
2. RECENT ACCOUNTING PRONOUNCEMENTS
 
     In October 1997, the AICPA issued Statement of Position No. 97-2 (SOP
97-2)"Software Revenue Recognition", which Network Associates has adopted for
transactions entered into during the year beginning 1 January 1998. SOP 97-2
provides guidance for recognizing revenue on software transactions and
supersedes previous guidance provided by SOP91-1, "Software Revenue
Recognition." Under SOP 97-2, revenue from product licenses is recognized when a
signed agreement or other persuasive evidence of an arrangement exists, the
software or system has been shipped (or software has been electronically
delivered), the license fee is fixed and determinable, and collection of the
resulting receivable is probable. For contracts with multiple
elements/obligations, (e.g. software products, upgrades/enhancements,
maintenance and services), revenue is allocated to each element of the
arrangement based on Network Associates' evidence of fair value as determined by
the amount charged when the element is sold separately. Maintenance revenue for
providing product updates and customer support is deferred and recognized
ratably over the service period. Revenue on rental units under operating leases
and service agreements is recognized over the term of the rental agreement or
the period during which services are expected to be performed. Revenue generated
from products sold through traditional channels where the right of return exists
is reduced by reserves for estimated sales returns.
 
     In March 1998, the AICPA issued Statement of Position No. 98-4 (SOP 98-4),
"Deferral of the Effective Date a Provision of SOP 97-2, Software Revenue
Recognition." SOP 98-4 defers, for one year, the application of certain passages
in SOP 97-2, which limit what is considered vendor-specific objective evidence
(VSOE) necessary to recognize revenue for software licenses in multiple-element
arrangements when undelivered elements exist. Additional guidance is expected to
be provided prior to adoption of any resulting final amendments related to the
deferred provisions of SOP 97-2. Because of the uncertainties related to the
outcome of these proceedings, the impact, if any, on future financial results of
Network Associates is not currently determinable. Adoption of the remaining
provisions of SOP 97-2 as amended, did not have a material impact on revenue
recognition during the first quarter of 1998.
 
     Network Associates has adopted the provisions of Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income," effective 1
January, 1998. This statement requires the disclosure of comprehensive income
and its components in a full set of general-purpose financial statements.
Comprehensive income is defined as net income plus revenues, expenses, gains and
losses that, under generally accepted accounting principles, are excluded from
net income. The components of comprehensive income, which are excluded from net
income, are

        NOTICE TO CONDENSED CONSOLIDATED FINANCIAL STATEMENT (CONTINUED)
                                  (UNAUDITED)
 
not significant individually or in aggregate, and therefore, no separate
statement of comprehensive income has been presented.
 
     In July 1997, the Financial Accounting Standards Board issued Statement of
Accounting Standards No. 131 (SFAS 131), "Disclosures about Segments of an
Enterprise and Related Information", which requires companies to report certain
information about operating segments, including certain information about their
products, services, the geographic areas in which they operate and their major
customers. This statement supersedes FASB Statements Nos. 14, 18, 24 and 30.
SFAS 131 is effective for financial statements for fiscal years beginning after
15 December 1997. Network Associates is evaluating the requirements of SFAS 131
and the effects, if any, on Network Associates' current reporting and
disclosures.
 
 3. NET INCOME PER SHARE
 
     In accordance with the disclosure requirements of SFAS 128, a
reconciliation of the numerator and denominator of basic and diluted net income
per share calculations is provided as follows (in thousands, except per share
amounts):

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
                          AUDITED FINANCIAL STATEMENTS
 
To the Stockholders
Networks Associates, Inc.
Santa Clara, California
 
     We have audited the accompanying consolidated balance sheets of Networks
Associates Inc., (formerly McAfee Associates, Inc.) and subsidiaries as of 31
December 1997 and 1996, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended 31 December 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Network
Associates Inc. and subsidiaries as of 31 December 1997 and 1996 and the results
of their operations and their cash flows for each of the three years in the
period ended 31 December 1997, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
     Networks Associates, Inc. (the Company), formerly McAfee Associates, Inc.,
develops, markets, distributes and supports network security and management
software products. The Company's markets are worldwide and include corporate,
governmental, and institutional users as well as resellers and distributors
throughout the world. Software products and updates are delivered primarily
through electronic distribution under two-year subscription licenses and as
boxed product sold through the retail channel. International sales and support
are provided by subsidiaries in principal European markets and independent
agents and distributors elsewhere internationally. The Company changed its name
to Networks Associates, Inc. in connection with the merger with Network General,
in December 1997.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Financial Statement Presentation:
 
     The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated.
 
  Use of Estimates:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reported period. Actual
results could differ from those estimates.
 
  Certain Risks and Concentrations:
 
     The Company's product revenues are concentrated in the personal computer
software industry which is highly competitive and rapidly changing. Significant
technological changes in the industry or customer requirements, or the emergence
of competitive products with new capabilities or technologies could adversely
affect operating results. In addition, a significant portion of the Company's
revenue and net income is derived from international sales and independent
agents and distributors. Fluctuations of the U.S. dollar against foreign
currencies, changes in local regulatory or economic conditions, piracy or
non-performance by independent agents could adversely affect operating results.
 
     The Company maintains the majority of cash balances and all of its
marketable securities with six financial institutions. The Company invests with
high credit quality financial institutions and, by policy, limits the amount of
credit exposure to any one financial institution. The Company has significant
amounts receivable from customers across a broad demographic base. Management of
the Company performs ongoing credit evaluations of its customers and maintains
allowances for doubtful accounts.
 
     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 products so as 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 materially adversely affect the Company's results of operations.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Foreign Currency Translation:
 
     The Company considers the local currency to be the functional currency for
its international subsidiaries. Assets and liabilities denominated in foreign
currencies are translated using the exchange rate on the balance sheet date.
Revenues and expenses are translated at average exchange rates prevailing during
the year. Translation adjustments resulting from this process are charged or
credited to equity. Foreign currency transaction gains and losses, which to date
have not been material, are included in the determination of net income.
 
  Revenue Recognition:
 
     Revenue from product licenses is generally recognized when a customer
purchase order has been received, a license agreement has been delivered, the
software or system has been shipped (or software has been electronically
delivered), remaining obligations are insignificant, and collection of the
resulting account receivable is probable. Maintenance revenue for providing
product updates and customer support is deferred and recognized ratably over the
service period. For subscription sales that have the maintenance fee included
with the licensing fee, maintenance revenue is derived based upon the amount
charged for such services when they are sold separately. Revenue from hardware
products is recognized upon shipment subject to a reserve for returns. Revenues
on rental units under operating leases and service agreements are recognized
ratably over the term of the rental or service period.
 
     Revenue generated from products sold through traditional channels where the
right of return exists is reduced by reserves for estimated sales returns. Such
reserves are based on estimates developed by management. As unsold products in
these distribution channels are exposed to rapid changes in consumer preferences
or technological obsolescence due to new operating environments, product updates
or competing products, it is reasonably possible that these estimates will
change in the near term.
 
     Prior to 1 July 1995 revenue from subscription licenses for anti-virus
software was recognized ratably over a two year period as the Company did not
separately sell the product license and maintenance. Effective 1 July 1995, the
Company began to sell these components separately and currently recognizes, upon
the initial sale, 80 per cent. of the total fee as product license revenue and
defers 20 per cent. of the fee as maintenance. The maintenance fee is recognized
over the service period, generally two years. The effect of this change was to
increase 1995 net income by $7.7 million ($0.16 per share).
 
  Advertising:
 
     Advertising costs are expensed as incurred and included in "Marketing and
Sales Expenses."
 
  Research and Development:
 
     Research and development expenditures are charged to operations as
incurred. Under the Company's development process, technological feasibility is
established on completing a working model. Subsequent costs for the Company have
not been significant and all software development costs have therefore been
expensed.
 
  Cash and Cash Equivalents:
 
     Cash equivalents are comprised of highly liquid debt instruments with
original maturities of 90 days or less.

                   NETWORKS ASSOCIATES, INC. AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Marketable Securities:
 
     All marketable securities are classified as either available-for-sale or
held-to-maturity. Available-for-sale securities are carried at fair value, and
held-to-maturity securities are stated at cost, adjusted for amortization or
premiums and accretion of discounts to maturity, in accordance with Statement of
Financial Accounting Standards No. 115 ("SFAS 115"). Current marketable
securities are those with maturities less than one year from the balance sheet
date. Non-current marketable securities are those with maturities greater than
one year from the balance sheet date. Unrealized gains and losses on marketable
securities classified as available-for-sale, when material, are reported net of
related taxes as a separate component of stockholders' equity. Realized gains
and losses on sales of all such investments are reported in earnings and
computed using the specific identification cost method. No debt or equity
securities were classified as held-to-maturity at 31 December 1997.
 
  Inventories:
 
     Inventories are stated at the lower of cost (first-in, first-out) or market
and include material and related manufacturing overhead.
 
  Fixed Assets:
 
     Fixed assets are stated at cost. Depreciation and amortization of fixed
assets is provided using the straight-line method over the estimated useful
lives of the assets (2 to 5 years).
 
  Intangible Assets:
 
     Intangible assets include the estimated fair market values of purchased
technology when the related products or products under development are
considered technologically feasible and goodwill arising from acquisitions and
other intangibles. Intangibles are amortized over their estimated useful lives
(typically three years to five years).
 
  Fair Value of Financial Instruments:
 
     Carrying amounts of the Company's financial instruments including cash and
cash equivalents, marketable securities, accounts receivable, accounts payable
and accrued liabilities approximate fair value due to their short maturities.
 
  Stock Based Compensation:
 
     The Company accounts for stock based compensation using the intrinsic value
method prescribed by APB Opinion No. 25, "Accounting for Stock Issued to
Employees." Accordingly, compensation cost for stock options is measured as the
excess, if any, of the quoted market price of the Company's stock at the date of
the grant over the amount an employee must pay to acquire the stock. The Company
has adopted the disclosure-only provisions of Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation."
 
  Net Income Per Share:
 
     Net income (loss) per share has been computed in accordance with SFAS 128.
Basic net income (loss) per share is computed using the weighted average common
shares outstanding during the period. Diluted net income per share is computed
using the weighted average common shares and common equivalent shares
outstanding during the period.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Stock Dividend:
 
     During October 1995 and April and October, 1996, the Company declared and
paid stock dividends of one share of common stock for every two shares of common
stock outstanding. All per share data contained herein has been restated to
reflect the increased number of shares outstanding.
 
3. BUSINESS COMBINATIONS AND ACQUISITIONS
 
  MERGER WITH NETWORK GENERAL CORPORATION
 
     On 1 December 1997, the Company acquired Network General Corporation
(Network General), a provider of network fault and performance management
solutions for approximately 17.9 million shares of the Company's common stock.
The Company also assumed and exchanged all options to purchase Network General
stock for options to purchase approximately 3.3 million shares of the Company's
common stock. The transaction was accounted for as a pooling of interests and
therefore all prior period financial statements have been restated to include
the results of Network General for all periods presented. On 1 December 1997, in
connection with the merger, McAfee changed its name to Networks Associates, Inc.
Network General had a fiscal year ended 31 March. Restated financial statements
combine Network General results for the fiscal years ended 31 March 1997 and
1996 with the results for the years ended 31 December 1996 and 1995,
respectively. In order to conform Network General's fiscal year end to the
Company's fiscal year end, the consolidated statement of operations for the year
ended 31 December 1997 includes the three months ended 31 March 1997 for Network
General which are also included in the consolidated statement of operations for
the year ended 31 December 1996. Revenue and net loss of Network General for
such period were $68.0 million and $6.4 million, respectively. Stockholders'
equity for the year ended 31 December 1997 has been adjusted to eliminate these
amounts.
 
     Separate and combined results of operations for the periods prior to the
merger are as follows:

5. DERIVATIVES
 
     During fiscal year 1997, the Company began using forward foreign exchange
contracts to hedge certain assets denominated in foreign currencies. For these
instruments, risk reduction is assessed on a transaction basis and the
instruments are designated as, and effective as a hedge and are highly inversely
correlated to the hedged item as required by generally accepted accounting
principles. Gains and losses on these hedges are included in the carrying amount
of the assets and are ultimately recognized in income. If a hedging instrument
ceases to qualify for hedge accounting, it is accounted for on a mark to market
basis and any subsequent gains and losses are recognized currently in income.
The Company does not use any derivatives for trading or speculative purposes.
 
  Forward Exchange Contracts
 
     The Company conducts business globally. As a result, it is exposed to
movements in foreign currency exchange rates. The Company enters into forward
exchange contracts to hedge exposures associated with nonfunctional currency
assets and liabilities denominated in Canadian, Australian and several European
currencies.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     The Company does not generally hedge anticipated foreign currency cash
flows nor does the Company enter into forward contracts for trading purposes.
Gains and losses on the contracts are reported in other income and generally
offset gains or losses from the revaluation of nonfunctional currency assets and
liabilities. The forward contracts range from one to three months in original
maturity. The forward contracts outstanding and their unrealized gains and
(losses) are presented below (in thousands):

     The Company presently intends to move its headquarters to larger facilities
in Santa Clara, California. To that end, the Company has agreed, as the assignee
of certain rights of the existing tenant, to rent a facility of approximately
200,000 square feet commencing on or about 1 April 1998. The underlying lease is
set to expire in 2013.
 
8. NETWORK GENERAL SHARE REPURCHASE PROGRAM
 
     In July 1993, the Board of Directors of Network General authorized Network
General to repurchase up to 1,666,800 shares of its common stock on the open
market to satisfy commitments under its stock option and stock purchase plans.
 
     In fiscal year 1996, up to an additional 1,666,800 shares of Network
General common stock were authorized for repurchase for the same purpose. At 1
December 1997, Network General had repurchased and retired 1,954,323 shares at
an aggregate cost of $92,574,000.
 
9. EMPLOYEE BENEFIT PLANS
 
  401(k) and Profit Sharing Plan:
 
     Under the Company's 401(k) and Profit Sharing Plans, the Board of
Directors, at its discretion, can match employee contributions in an amount not
to exceed 20 per cent. of total compensation. Annual amounts provided by the
Company under the plan to date have not been material.
 
  Employee Stock Purchase Plan:
 
     Under the 1994 Employee Qualified Stock Purchase Plan, the Company can
grant stock purchase rights to all eligible employees during one year offering
periods with exercise dates approximately every six months (beginning each
August and February). The Company has reserved 506,250 shares of common stock
for issuance under the plan. Shares are purchased through employees' payroll
deductions at exercise prices equal to 85 per cent. of the lesser of the fair
market value of the Company's common stock at either the first day of an
offering period or the last day of such offering period. No participant may
purchase more than $25,000 worth of common stock in any one calendar year.
 
10. STOCKHOLDERS' EQUITY
 
Preferred Stock:
 
     The Company has authorized 5,000,000 shares of preferred stock, par value
$.01 per share. The Company's Board of Directors has authority to provide for

preferred stock in series, to establish from time to time the number of shares
to be included in each such series and to fix the designation, powers,
preferences and rights of the shares of each such series and the qualifications,
limitations or restrictions thereof, without any further vote or action by the
shareholders.
 
     In connection with the acquisition of FSA, the Company issued one share of
Series A preferred stock. The share of Series A preferred stock has no
preferential rights other than the right to cast a number of votes equal to the
number of common shares issuable in exchange for certain exchangeable non-voting
shares of FSA. At 31 December 1997, 325,062 shares of the Company's common stock
were reserved for conversion.
 
  Stock Option Plans:
 
     In June 1997, the Board of Directors approved the 1997 Stock Incentive Plan
(the "1997 Plan") to replace the 1995 Stock Incentive Plan. Under the 1997 Plan,
the Company has reserved 5,850,000 shares for issuance to employees, officers,
directors, third-party contractors and consultants. The plan provides for an
option price no less than 100 per cent. of the fair market value of the
Company's common stock on the date of grant for incentive stock options granted
to employees and officers (including directors who are also employees) or 85 per
cent. of the fair market value on the date of grant for all others. The options
may be exercisable immediately, or over time, generally vest 25 per cent. one
year after commencing employment or from date of grant and vest thereafter in
monthly increments over three years. All options under the option plan expire
ten years after grant.
 
     Under the amended Stock Option Plan for Outside Directors, the Company has
reserved 421,875 shares for issuance to certain members of its Board who are not
employees of the Company or any affiliated corporation. The plan provides for an
option price at fair market value of the Company's common stock on the date of
grant. The initial grant to each outside director generally vests ratably over a
three-year period. Subsequent option grants will vest after three years from the
date of grant. All options under the option plan expire ten years after grant.

     The fair market value of options granted has been calculated using the
Black-Scholes option pricing model using the multiple option approach. A typical
option grant vests over a four year period. Parameters for the option analysis
are listed below.

</TABLE>
 
     The weighted average expected life of the option grants was estimated based
on examination of previously exercised options over the life of the program.
Volatility was estimated on a monthly basis since the Company became public in
October of 1992. The average volatility for the twelve months ending December
1997 and 36 month period from January 1995 through December 1997 was 66 per
cent. Since the volatility has been relatively stable one value was selected for
all segments. The Company has not paid a dividend, and has no plans to do so.
 
     The weighted average fair value of options granted in 1997, 1996 and 1995
was $27.85, $17.44 and $10.05, respectively.
 
     The Company has also estimated the fair value of purchase rights issued
under the Employee Stock Purchase Program. Rights under this plan were also
evaluated using the Black-Scholes option pricing model. The Company's plan is
described in Note 7. Purchase periods occur twice yearly and each effectively
contains a 6 and 12 month option.

This policy may or may not continue.
 
     Warrants:
 
     Pursuant to the acquisition of PGP, the Company issued warrants to purchase
250,000 shares of common stock at a price of $60 per share, which expire,
subject to certain extensions, on 5 June 1999, all of which were outstanding at
31 December 1997. In addition, warrants for the purchase of 4,227 shares of
Common Stock issued in connection with the Company's 1995 acquisition of
Assurdata were outstanding at 31 December 1997.

     The valuation allowance relates to the tax benefit of operating losses of
PGP and 3DV. The operating losses are subject to certain annual limitations as a
result of the acquisition and may expire before the Company can utilize them.
Accordingly, a valuation allowance has been established.
 
     Realization of the remaining net deferred tax assets of $44,852,000 as of
31 December 1997 is dependent on generating sufficient taxable income to offset
future deduction of the related items. Although realization is not assured,
management believes it is more likely than not that all of the net deferred tax
assets will be realized. The amount of the deferred tax asset considered
realizable, however, could be reduced in the near term if estimates of future
taxable income are reduced.
 
     U.S. income taxes were not provided for on a cumulative total of
approximately $17,038,000 of undistributed earnings for certain non-U.S.
subsidiaries. The Company intends to reinvest these earnings indefinitely in
operations outside the United States.
 
     The Company's effective tax rate on income before income taxes differs from
the U.S. Federal statutory regular tax rate as follows:

13. BUSINESS SEGMENT INFORMATION:
 
     The Company operates in one industry segment and markets and services its
products in the United States and in foreign countries through its own direct
sales organization and through independent agents and distributors. In 1997,
foreign operations accounted for approximately 28 per cent. of the Company's net
revenue, but less than 10 per cent. of the Company's net income, and
identifiable assets. No one customer accounted for more than 10 per cent. of net
revenue during fiscal 1997, 1996 and 1995.
 
     Net revenue information by geographic area is as follows (in thousands of
U.S. dollars):

14. LITIGATION:
 
     On 24 April 1997, the Company 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 the Company.
Symantec alleges that the Company's 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
20 July 1997, Symantec sought leave to amend its complaint to include additional
allegations of copyright infringement and trade secret misappropriation
pertaining to the Company's "VirusScan" product. Symantec sought injunctive
relief and unspecified money damages. On 6 October 1997, the Court issued an
order granting Symantec's motion to amend its complaint and enjoining the
Company 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
                                       93

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
product." On 19 December 1997, the Court denied Symantec's motion to enjoin sale
or distribution of the Company's current PC Medic product. On 11 February 1998,
Symantec filed another motion seeking leave to again amend its complaint to
include additional allegations of trade secret misappropriation, interference
with economic advantage and business relations and violations of the Racketeer
Influenced and Corrupt Organization Act ("RICO"), in connection with the alleged
use at the Company by a former Symantec employee of allegedly proprietary
Symantec customer information. Symantec also filed a motion for a preliminary
injunction relating to these new allegations, and has scheduled both motions for
hearing on 15 May 1998. Trial is currently set for September 1998.
 
     On 13 May 1997, Trend Micro, Inc. ("Trend") filed suit in United States
District Court for the Northern District of California against both the Company
and Symantec. Trend alleges that the Company's "WebShield" and "GroupShield"
products infringe a Trend patent which issued on 22 April 1997. Trend's
complaint seeks injunctive relief and unspecified money damages. On 6 June 1997,
the Company filed its answer denying any infringement. The Company also filed a
counterclaim against Trend alleging unfair competition, false advertising, trade
libel, and interference with prospective economic advantage. On 19 September
1997, Symantec filed a motion to sever Trend's action against the Company from
its action against Symantec. The Company did not oppose Symantec's motion to
sever, other than to recommend a joint hearing on patent claim interpretation.
On 19 December 1997, the Court granted Symantec's motion to sever and adopted
the Company's recommendation regarding a joint hearing on patent claim
interpretation. As a result of the Court's decision, Trend's actions against the
Company and Symantec will proceed separately. The exact terms of the severance
order have not yet been approved by the Court, and the Court has yet to reset
key dates for discovery and trial in the two cases. The Company anticipates that
the Court will shortly reset the date for the joint patent claim interpretation
hearing for late June or July, 1998. Thirty days after the joint patent claim
interpretation hearing, the Court has indicated it will set further dates for
discovery and trial.
 
     On 6 May 1997, RSA Data Security, Inc. ("RSA") filed a lawsuit against PGP,
a wholly owned subsidiary of the Company since 9 December 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 22 May
1997, PGP filed a motion to compel arbitration of the action pursuant to an
arbitration clause in the License Agreement. PGP's motion was granted on 9
October 1997. The Court stayed the state court proceedings and ordered the
action to arbitration. The arbitration proceedings are in the preliminary
stages.
 
     On 14 October 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 4 November 1997, PGP moved to stay the federal action, or,
in the alternative, compel it to arbitration. On 23 December 1997, RSA filed a
motion to amend its complaint to include the Company as defendant. PGP's motion
to stay and RSA's motion to amend its complaint are scheduled to be heard by the
federal court in February 1998.
 
     On 15 September 1997, the Company was named as a defendant in a patent
infringement action filed by Hilgraeve Corporation ("Hilgraeve") in the United
States District Court, Eastern District of Michigan. Hilgraeve alleges that the
Company's "VirusScan" product infringes a Hil-
 
                                       94

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
graeve patent which was issued on 7 June 1994. Hilgraeve's action seeks
injunctive relief and unspecified money damages. The case is in discovery.
 
     Although the Company has not been served in any suit, three companies
(including Network Associates Corporation in California and Network Associates,
Inc. in Oregon) have made claims (including various trademark claims) or demands
with respect to the Company's use of the name Network Associates.
 
     While there can be no assurance that the above litigation will not have a
material adverse effect on the Company, management does not expect that the
ultimate costs to resolve these matters will have a material adverse effect on
the Company's consolidated financial position, results of operations, or cash
flow.
 
15. RECENT ACCOUNTING PRONOUNCEMENTS
 
     In July 1997, the Financial Accounting Standards Board issued Statement of
Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive Income", which
requires a separate financial statement showing changes in comprehensive income,
is effective for financial statements issued for fiscal years beginning after 15
December 1997. SFAS 130 requires reclassification of all prior-period financial
statements for comparative purposes. The Company is evaluating alternative
formats for presenting this information, but does not expect this pronouncement
to materially impact the Company's results of operations.
 
     In July 1997, the Financial Accounting Standards Board issued Statement of
Accounting Standards No. 131 (SFAS 131), "Disclosures about Segments of an
Enterprise and Related Information", which requires companies to report certain
information about operating segments, including certain information about their
products, services, the geographic areas in which they operate and their major
customers. This statement supersedes FASB Statements Nos. 14, 18, 24 and 30.
SFAS 131 is effective for financial statements for fiscal years beginning after
15 December 1997. The Company is evaluating the requirements of SFAS 131 and the
effects, if any, on the Company's current reporting and disclosures.
 
     Statement of Position (SOP) 97-2, "Software Revenue Recognition" was issued
in October 1997 and addresses software revenue recognition matters primarily
from a conceptual level and does not include specific implementation guidance.
The SOP supersedes SOP 91-1 and is effective for transactions entered into for
fiscal years beginning after 15 December 1997. Based on its reading and
interpretation of SOP 97-2, the Company believes it is currently in compliance
with the final standard. However, detailed implementation guidelines for this
standard have not yet been issued. Once issued, such detailed implementation
guidance could lead to unanticipated changes in the Company's current revenue
accounting practices, and such changes could be material to the Company's
revenues and earnings.
 
16. SUBSEQUENT EVENTS:
 
     On 10 February 1998, the Company agreed to issue in a private placement
zero coupon convertible subordinated debentures due in 2018. The debentures,
with an aggregate face amount at maturity of $770 million, are expected to
generate net proceeds to the Company of approximately $293.6 million (after
deducting the fee paid to the initial purchaser of the debentures but no other
expenses of the placement). The initial price to the public for the debentures
was $391.06 per $1,000 of face amount at maturity, which equates to a yield to
maturity over the term of the bonds of 4.75 per cent. (on a semi-annual bond
equivalent basis). The debentures are convertible into Common Stock at the rate
of 5.692 shares per $1,000 of face amount at maturity, which equates to
 
                                       95

                   NETWORKS ASSOCIATES, INC. AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
an initial conversion price of $68.70 per share. On such date, the Company also
granted an option to purchase on or prior to 10 March 1998 up to an additional
$115.5 million aggregate principal amount due at maturity of debentures to cover
over-allotments, if any. If such over-allotment option is exercised in full, the
Company would expect to receive additional net proceeds of approximately $44
million (after deducting the fees paid to the initial purchaser of the
debentures but no other expenses of the placement). On 13 February 1998, the
initial purchaser exercised the option in full.
 
     Pending Acquisitions (Unaudited): On 22 February 1998, the Company agreed
to acquire, in a pooling of interest merger, Trusted Information Systems, Inc.
("TIS"), a publicly traded provider of security solutions for the protection of
computer networks. In the acquisition, a wholly owned subsidiary of the Company
will merge with and into TIS. Each outstanding share of TIS common stock will be
converted into 0.323 shares of common stock of the Company. The acquisition,
which is expected to close in the second quarter of 1998, is subject to
customary conditions to closing including TIS stockholder approval and
Hart-Scott-Rodino anti-trust clearance.

         DR SOLOMON'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     The following management's discussion and analysis at Part B of this
Appendix for the nine month periods ended 28 February 1998 and 1997 should be
read in conjunction with the condensed unaudited consolidated financial
statements of Dr Solomon's and the related notes referred to at Part B of
Appendix 2 of this document. Such results are not necessarily indicative of the
results to be expected for the full year or any future periods.
 
     The following management's discussion and analysis at Part C of this
Appendix for the financial years ended 31 May 1997, 1996 and 1995 should be read
in conjunction with the audited consolidated financial statements of Dr
Solomon's and the related notes set out at Part B of Appendix 2 of this
document.
 
     The consolidated financial statements have been prepared in accordance with
U.K. GAAP, which differs in certain significant respects from U.S. GAAP. See
Note 22 to the audited consolidated financial statements.
 
PART A
 
OVERVIEW
 
     Dr Solomon's develops, markets and supports anti-virus software programs
for PCs and PC networks. Dr Solomon's products provide effective and easy to use
software solutions to the risks posed by the proliferation of new and
increasingly sophisticated types of computer viruses. Dr Solomon's principal
product line is the "Dr Solomon's Anti-Virus Toolkit" family of anti-virus
software programs. Since its introduction in 1989, the Toolkit has become one of
the leading global anti-virus software programs. Dr Solomon's sells its products
in the United Kingdom, the United States, Germany, Switzerland and Australia
through direct sales forces, corporate resellers and distributors and elsewhere
internationally through republishers and distributors.
 
     Dr Solomon's recognizes revenues in accordance with the American Institute
of Certified Public Accountant's Statement of Position of Software Revenue
Recognition (SOP 97-2). Dr Solomon's revenues derive from (i) product licenses,
(ii) sales of boxed products and (iii) providing updates to boxed product
purchasers. Dr Solomon's recognizes revenues from product licenses and update
services evenly over the terms of the contracted service (normally one, two or
three years in the case of product licenses and one year in the case of update
services). Dr Solomon's recognizes 50 per cent. of the revenues from sales of
those boxed products which include an update service at the time of sale and the
remaining 50 per cent. evenly over the term of the update service included in a
sale (normally 12 months). For those boxed products not including an update
service, revenue is recognized at time of sale.
 
     Although Dr Solomon's has experienced significant growth in bookings, Dr
Solomon's does not believe that such growth rates are sustainable, particularly
in those markets where growth has been from a small market share. The ratio of
net deferred revenue to bookings depends upon the relative levels of bookings in
previous years and the current year, the mix of sales between product types and
the average length of licenses. Dr Solomon's believes that period-to-period
comparisons of its financial results are not necessarily meaningful and should
not be relied upon as an indication of future performance.
 
RECENT DEVELOPMENTS
 
     Dr Solomon's is currently reviewing its results of operations for the three
months ended 31 May 1998. Based on preliminary indications, which are subject to
additional review and
 
                                       97
<PAGE>   98
 
amendment, bookings for such period were approximately L20.5 million (compared
to L14.8 million for the three months ended 31 May 1997). Dr Solomon's does not
currently expect that its financial results for such period will deviate
materially from historical trends adjusted for this level of bookings.

TURNOVER
 
     Turnover was L41.5 million for the nine months ended 28 February 1998
compared to L25.4 million for the same period in the 1997 financial year,
representing an increase of 63.3 per cent.
 
BOOKINGS
 
     Bookings were L48.2 million for the nine months ended 28 February 1998
compared to L30.8 million for the same period in the 1997 financial year,
representing an increase of 56.8 per cent.
 
     Bookings in the United Kingdom increased to L25.4 million for the nine
months ended 28 February 1998 compared to L18.7 million for the same period in
the 1997 financial year, representing an increase of 36.0 per cent. However, the
proportion of total bookings attributable to the United Kingdom fell from 60.8
per cent. to 52.7 per cent. over the same period.
 
     Bookings in the United States increased to L9.9 million for the nine months
ended 28 February 1998 compared to L3.5 million for the same period in the 1997
financial year and these now represent 20.5 per cent. of worldwide bookings
compared to 11.3 per cent. for the same period in the 1997 financial year. The
increase reflected mainly continuing strong growth of the retail boxed product,
but also the contribution from the acquisitions in the second quarter of 1998 of
the Virex and netOctopus product lines.
 
     Bookings in Germany increased by 52.8 per cent. for the nine months ended
28 February 1998 to L5.3 million, representing 11.0 per cent. of worldwide
bookings compared to L3.5 million (11.2 per cent.) for the same period in the
1997 financial year. If the Sterling/Deutsche Mark exchange rates had been the
same for the nine months ended 28 February 1998 as for the same period in the
1997 financial year, the Sterling equivalent of bookings would have been L6.0
million, a 72.3 per cent. increase on the same period in the 1997 financial
year.
 
     Bookings in the rest of the world increased by 48.6 per cent. for the nine
months ended 28 February 1998 to L7.6 million and represented 15.8 per cent. of
worldwide bookings compared to L5.1 million (16.7 per cent.) for the same period
in the 1997 financial year.
 
NET DEFERRED REVENUE
 
     Net deferred revenue was L6.7 million for the nine months ended 28 February
1998 compared to L5.3 million for the same period in the 1997 financial year. As
a percentage of bookings, net deferred revenue decreased from 17.3 per cent. for
the nine months ended 28 February 1997 to 13.9 per cent. for the same period in
1998, reflecting mainly the increased levels of bookings on retail boxed
products on which revenue is not deferred.
 
COST OF SALES
 
     Dr Solomon's cost of sales is composed of the cost of freight, media,
software duplication, assembly, manuals and packaging, commissions payable to
U.K. resellers acting as agents of Dr Solomon's and an allowance for
co-operative marketing costs based on bookings for certain distributors and
resellers. All costs are charged to the profit and loss account at the time of
invoicing; none are deferred. Cost of sales as a percentage of bookings
increased from 17.0 per cent. for the nine months ended 28 February 1997 to 19.7
per cent. for the same period in 1998, resulting mainly from the introduction
during the period in 1998 of retail products in the United States and the United
Kingdom on which material and co-operative marketing costs are proportionately
higher.

OPERATING EXPENSES
 
     Operating expenses, which comprise distribution costs, administrative
expenses and other operating income, were L22.5 million for the nine months
ended 28 February 1998, compared to L14.2 million for the same period in the
1997 financial year, representing an increase of 58.7 per cent. As a percentage
of bookings, operating expenses were 46.5 per cent. for the nine months ended 28
February 1998, compared to 46.1 per cent. for the same period in the 1997
financial year.
 
     Salaries and related costs, the largest component of operating expenses,
were L10.5 million for the nine months ended 28 February 1998, compared to L6.2
million for the same period in the 1997 financial year. As a percentage of
bookings, salaries and related costs were 21.8 per cent. for the nine months
ended 28 February 1998, compared to 20.1 per cent. for the same period in the
1997 financial year.
 
     Another significant component of operating expenses is marketing, primarily
advertising, trade shows and literature, which were L3.9 million for the nine
months ended 28 February 1998, compared to L2.1 million for the same period in
the 1997 financial year. As a percentage of bookings, marketing expenses were
8.1 per cent. for the nine months ended 28 February 1998, compared to 6.8 per
cent. for the same period in the 1997 financial year.
 
     Research and product development expenses, comprising primarily salaries
and benefits for the software development, test and technical support staff plus
depreciation on equipment, were L5.0 million for the nine months ended 28
February 1998, compared to L2.8 million for the same period in the 1997
financial year. As a percentage of bookings, research and product development
expenses were 10.4 per cent. for the nine months ended 28 February 1998,
compared to 9.1 per cent. for the same period in the 1997 financial year.
 
OPERATING PROFIT
 
     Operating profit was L9.6 million for the nine months ended 28 February
1998, compared to L6.1 million for the same period in the 1997 financial year,
representing an increase of 58.7 per cent. As a percentage of bookings,
operating profit was 19.9 per cent. for the nine months ended 28 February 1998,
compared to 19.6 per cent. for the same period in the 1997 financial year.
 
INTEREST RECEIVABLE AND INTEREST PAYABLE
 
     Net interest receivable was L1.1 million for the nine months ended 28
February 1998, compared to net interest payable of L0.5 million for the same
period in the 1997 financial year.
 
TAX ON PROFIT ON ORDINARY ACTIVITIES
 
     Income taxes were L3.8 million for the nine months ended 28 February 1998,
compared to L2.4 million for the same period in the 1997 financial year. Dr
Solomon's effective tax rates were 35.4 per cent. for the nine months ended 28
February 1998, compared to 44.1 per cent. for the same period in the 1997
financial year. The high rates of effective taxation, compared to the statutory
U.K. rate of 33 per cent. (reduced to 31 per cent. with effect from April 1997),
are due primarily to the losses incurred in the United States that could not be
offset against U.K. profits for taxation purposes.
 
PROFIT ON ORDINARY ACTIVITIES AFTER TAXATION
 
     Profit on ordinary activities after taxation was L6.9 million for the nine
months ended 28 February 1998, compared to L3.1 million for the same period in
the 1997 financial year.

</TABLE>
 
     Net cash inflow from operating activities was L12.5 million for the nine
months ended 28 February 1998, compared to L8.4 million for the same period in
the 1997 financial year. This increased operating cash flow was primarily due to
increased bookings and improved operating results. Accounts receivable, net of
allowance for doubtful amounts, were L14.7 million at 28 February 1998, compared
to L8.6 million at 28 February 1997, representing 64 days bookings and 57 days
bookings respectively.
 
     Investment in fixed assets increased from L1.6 million for the nine months
ended 28 February 1997 to L6.2 million for the same period in the 1998 financial
year, the latter including an investment of L1.7 million in freehold premises
close to Dr Solomon's Aylesbury headquarters to accommodate expansion of its
group development and U.K. sales and technical support staff.
 
U.S. GAAP RECONCILIATION
 
     During the second quarter of the 1998 financial year, Dr Solomon's
purchased the Virex and netOctopus product lines through its U.S. subsidiary. In
addition, Dr Solomon's purchased the intellectual property rights to the Audit
product which it previously sold under license from the original developers.
Under U.K. GAAP, costs of acquisition in excess of the fair value of the
tangible net assets of acquired businesses at the date of acquisition may be
written off against shareholders equity either in the year of acquisition or in
future years. Dr Solomon's has written off such goodwill, amounting to L13.9
million, against shareholders equity in the year of acquisition.

the audited results of Dr Solomon's for the period from 7 February 1996 to 31
May 1996 and the audited results of S&S International for the year ended 31 May
1995. Dr Solomon's believes that this is the most meaningful presentation for
comparative purposes. References to a year or financial year shall, unless

TURNOVER
 
     Turnover was L37.2 million, L20.9 million and L11.3 million in the 1997,
1996 and 1995 financial years, respectively, representing increases of 78.1 per
cent. and 84.8 per cent. Although these increases were primarily attributable to
increases in turnover in the United Kingdom which increased from L8.6 million to
L22.4 million over this period, the proportion of group turnover attributable to
the United Kingdom fell from 75.8 per cent. to 60.2 per cent. Dr Solomon's U.S.
subsidiary, established in March 1995, increased turnover from L0.2 million in
the 1995 financial year to L4.4 million in 1997.
 
                                       102
<PAGE>   103
 
Dr Solomon's German subsidiary increased turnover from L0.8 million in the 1995
financial year to L3.2 million in 1997. In the Rest of the World, turnover
increased from L1.7 million in the 1995 financial year to L7.1 million in 1997.
 
BOOKINGS
 
     Bookings were L45.6 million, L28.3 million and L14.0 million in the 1997,
1996 and 1995 financial years, respectively, representing increases of 61.0 per
cent. and 102.8 per cent. Dr Solomon's believes that the higher rate of growth
in 1996 was due in part to the appearance of macro viruses in late summer 1995
and management has previously indicated that it did not expect this rate of
growth to be sustainable. Prices remained broadly stable throughout this period
and Dr Solomon's believes that the bookings increases reflect growth in the
market plus market share gains in some markets particularly the United States
and Germany.
 
     Bookings in the United Kingdom increased to L27.0 million in the 1997
financial year compared to L19.4 million in 1996 and L10.5 million in 1995,
representing year-on-year increases of 39.0 per cent. and 85.6 per cent.
respectively.
 
     Bookings in the United States increased by 231.1 per cent. to L6.6 million
in 1997 and these represented 14.6 per cent. of worldwide bookings compared to
L2.0 million (7.1 per cent.) for 1996 and L0.1 million (0.4 per cent.) for 1995.
Corporate license revenue grew sequentially each quarter in 1997 and an
increasing proportion of business was derived from the expanding corporate
reseller network. The retail boxed product was launched late in the third
quarter of the 1997 financial year, contributing significantly to bookings in
the fourth quarter.
 
     Bookings in Germany increased by 137.1 per cent. in 1997 to L4.6 million,
although in local currency the increase was 161.6 per cent., reflecting the
strength in sterling compared to the Deutsche mark during such period. This
represented 10.1 per cent. of worldwide bookings and compares with L1.9 million
(6.9 per cent.) in 1996 and L0.7 million (4.8 per cent.) in 1995.
 
     Bookings in the Rest of the World increased by 48.5 per cent. in 1997 to
L7.3 million and represented 16.1 per cent. of worldwide bookings compared to
L4.9 million (17.4 per cent.) in 1996 and L2.8 million (19.8 per cent.) in 1995.
 
NET DEFERRED REVENUE
 
     Net deferred revenue was L8.4 million, L7.4 million and L2.6 million in the
1997, 1996 and 1995 financial years, respectively. As a percentage of bookings,
net deferred revenue was 18.3 per cent. in 1997, 26.2 per cent. in 1996 and 19.0
per cent. in 1995. The fall between 1996 and 1997 reflected the lower rate of
increase in bookings compared to the previous year on a relatively stable
product mix plus the introduction of retail boxed products on which revenue is
not deferred.
 
COST OF SALES
 
     Cost of sales was L8.0 million, L4.4 million and L2.3 million in the 1997,
1996 and 1995 financial years, respectively, representing year-on-year increases
of 80.5 per cent. and 91.3 per cent. As a percentage of bookings, cost of sales
was 17.5 per cent. in 1997, 15.6 per cent. in 1996 and 16.6 per cent. in 1995.
The increase in cost of sales in 1997 was due solely to the introduction of the
retail product with its proportionately higher material and co-operative
marketing costs as well as the higher proportion of sales made through agents in
the United Kingdom.
 
OPERATING EXPENSES
 
     Operating expenses were L20.1 million in 1997, L13.1 million in 1996 and
L7.8 million in 1995, representing year-on-year increases of 53.7 per cent. and
66.9 per cent. As a percentage of bookings, operating expenses were 44.2 per
cent. in 1997, 46.3 per cent. in 1996 and 56.3 per cent. in 1995, reflecting the
operating leverage of the business as bookings grew. This reduction in
                                       103
<PAGE>   104
 
operating expenses as a percentage of bookings slowed in 1997 as Dr Solomon's
increased its investment in product development and quality staff and in its
sales and marketing activities, particularly in the United States. Dr Solomon's
does not anticipate any further reduction in operating expenses as a percentage
of bookings over the next few quarters.
 
     Salaries and related costs, the largest component of operating expenses,
were L8.9 million in 1997, L5.6 million in 1996 and L3.6 million in 1995,
representing year-on-year increases of 58.9 per cent. and 55.6 per cent. This
reflects an increase in average headcount from 145 in 1995 to 205 in 1996 and
308 in 1997. As a percentage of bookings, salaries and related costs were 19.5
per cent. in 1997, 19.8 per cent. in 1996 and 25.8 per cent. in 1995.
 
     Another significant component of operating expenses is marketing, primarily
advertising, trade shows and literature, which were L3.2 million in 1997, L1.8
million in 1996 and L1.3 million in 1995, representing year-on-year increases of
77.8 per cent. and 38.5 per cent. As a percentage of bookings, marketing
expenses were 7.1 per cent. in 1997, 6.4 per cent. in 1996 and 9.3 per cent. in
1995.
 
     Research and product development expenses, comprising primarily salaries
and benefits for the software development, test and technical support staff plus
depreciation on equipment, were L4.0 million in 1997, L2.1 million in 1996 and
L1.2 million in 1995, representing year-on-year increases of 90.5 per cent. and
77.7 per cent. As a percentage of bookings, research and product development
expenses were 8.8 per cent. in 1997, 7.6 per cent. in 1996 and 8.7 per cent. in
1995.
 
OPERATING PROFIT
 
     Operating profit was L9.1 million in 1997, L3.4 million in 1996 and L1.1
million in 1995. As a percentage of bookings, operating profit was 20.0 per
cent. in 1997, 11.9 per cent. in 1996 and 8.1 per cent. in 1995. The increase in
the level of operating profit in 1997 primarily reflects the 78.1 per cent.
increase in turnover compared to the 53.7 per cent. increase in operating
expenses.
 
INTEREST RECEIVABLE AND INTEREST PAYABLE
 
     Net interest payable was L0.2 million in 1997 and L0.5 million in 1996
compared to net interest receivable of L0.1 million in 1995. The 1997 figure
reflects net interest payable for the first two quarters in respect of
borrowings incurred in connection with the management buyout of Dr Solomon's in
February 1996 of L0.9 million, offset by interest receivable of L0.7 million for
the latter two quarters.
 
TAX ON PROFIT ON ORDINARY ACTIVITIES
 
     Income taxes were L3.7 million in 1997, L1.4 million in 1996 and L0.6
million in 1995. Dr Solomon's effective tax rates were 41 per cent. in 1997, 47
per cent. in 1996 and 48 per cent. in 1995. The high rates of effective
taxation, compared to the statutory U.K. rate of 33 per cent.(reduced to 31 per
cent. with effect from April 1997), were due primarily to the losses incurred in
the United States that could not be offset against U.K. profits for taxation
purposes.
 
PROFITS ON ORDINARY ACTIVITIES AFTER TAXATION
 
     Profit on ordinary activities after taxation was L5.3 million in 1997, L1.5
million in 1996 and L0.7 million in 1995.
 
EARNINGS PER SHARE
 
     Earnings per Dr Solomon's Ordinary Share were L0.098 (per Dr Solomon's
ADS -- L0.295) for the 1997 financial year.

</TABLE>
 
     Net cash inflow from operating activities was L14.0 million in 1997, L10.9
million in 1996 and L3.2 million in 1995. This increased operating cash flow was
primarily due to increased bookings and improved operating margins. Accounts
receivable, net of allowance for doubtful amounts, were L11.1 million at May 31,
1997, compared to L5.7 million at May 31, 1996, representing 60 days bookings
and 57 days bookings respectively.
 
     Net cash outflow from capital expenditure and financial investment was L2.4
million in 1997, L1.3 million in 1996 and L1.3 million in 1995. Investments in
fixed assets were L2.5 million in 1997, L1.7 million in 1996 and L1.4 million in
1995 and this increasing investment trend is expected to continue as staff
levels continue to grow. Acquisition costs in 1996 of L22.1 million related to
the Management Buyout in February 1996.
 
     During the year ended May 31, 1997, Dr Solomon's received L36.1 million
from the issue of ordinary share capital (net of expenses) mainly through a
public offering and has repaid borrowings and redeemed preference shares
totalling L25.4 million. Dr Solomon's held cash and deposit balances of L25.4
million at May 31, 1997. In the 1996 financial year, net cash inflow from
financing activities was L21.6 million, resulting from the issue of ordinary and
preference share capital and from borrowings, both to finance the management
buyout.
 
EFFECTS OF INFLATION
 
     Dr Solomon's believes that the current level of inflation will not have a
material impact on Dr Solomon's operations or financial condition.
 
CURRENCY FLUCTUATIONS
 
     Dr Solomon's consolidated financial statements are denominated in pounds
sterling, and changes in the exchange rate between the pound sterling and other
currencies (principally the U.S. dollar and the Deutsche mark) will affect the
translation of the financial results of Dr Solomon's non-U.K. subsidiaries into
pounds sterling for purposes of Dr Solomon's consolidated financial results, and
will also affect the pound sterling value of any amounts distributed to Dr
Solomon's by its subsidiaries. Such changes may also affect Dr Solomon's balance
sheet and changes in assets and liabilities resulting from exchange-rate
movements may result in foreign currency gains and losses being recorded.

          NETWORK ASSOCIATES' MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following management's discussion and analysis at Part B of this
Appendix should be read in conjunction with the condensed unaudited consolidated
financial statements for the financial quarter ended 31 March 1998 of Network
Associates and related notes referred to at Part B of Appendix 3 of this
document. Such results are not necessarily indicative of the results to be
expected for the full year or any future periods.
 
     The following management's discussion and analysis at Part C of this
Appendix for the financial years ended 31 December 1997, 1996 and 1995 should be
read in conjunction with the audited consolidated financial statements and
related notes thereto set out at Part B of Appendix 3 of this document.
 
PART A
 
OVERVIEW
 
     Network Associates' results of operations can fluctuate significantly on a
quarterly basis. Causes of such fluctuations may include the volume and timing
of new orders and renewals, the introduction of new products, distributor
inventory levels and return rates, company inventory levels, product upgrades or
updates released by Network Associates or its competitors, changes in product
prices, the impact of competitive pricing or products, timely availability and
acceptance of new products, changes in product mix, changes in the market for
anti-virus or network management software, inclusion of network security or
management software functionality in system software, failure to manage growth
and/or potential acquisitions, seasonality, trends in the computer industry,
general economic conditions, extraordinary events such as acquisitions or
litigation and the occurrence of unexpected events. Historically, renewals have
accounted for a significant portion of Network Associates' net revenue, however,
there can be no assurance that Network Associates will be able to sustain
current renewal rates in the future. In addition, revenue generated through
distribution channels tends to be non-linear and this may cause Network
Associates' revenue to fluctuate in the future. Network Associates' results for
any given period should not be relied upon as indicative of future performance.
 
     Network Associates' future earnings and stock price may be subject to
volatility in any period. Any shortfall in various operating results, including
licensing activity, product sales, net revenue, operating income, net income or
net income per share from historical levels or expectations of securities
analysts may have significant adverse effects on the trading price of Network
Associates' stock. Furthermore, other factors such as acquisitions or unforeseen
events in the technology or software industry or in Network Associates' day to
day activities can have a material adverse effect on Network Associates' stock
performance.

</TABLE>
 
NET REVENUE
 
     Net revenue includes product, revenues from software support, maintenance
contracts, education and consulting services as well as revenues from those
warranty, customer support and maintenance contracts which are deferred and
recognized over the related service period. Net revenue increased 33 per cent.
to U.S.$188.4 million in the three months ended 31 March 1998 from U.S.$141.4
million in the three months ended 31 March 1997. The increase was primarily due
to increases in the licensing of anti-virus software products to new customers,
renewing expiring anti-virus licenses, continued acceptance of Network
Associates' Sniffer products, continued acceptance of Network Associates'
consulting and support services as well as the growth of the installed customer
base and the resulting renewal of maintenance contracts. The increase is also
attributable to a lesser extent to the licensing of products (other than
anti-virus and Sniffer products) to new and existing customers as well as
expansion into indirect product distribution channels and international markets.
 
     Although Network Associates has had significant growth in net revenue and
net income (before acquisition and other related charges), Network Associates'
growth rate has slowed in recent periods. Network Associates has experienced
increased price competition for its products and Network Associates expects
competition to increase in the near-term, which may result in reduced average
selling prices for Network Associates' products. Due to these factors and
factors such as a maturing anti-virus market and an increasingly higher base
from which to grow, the historic revenue growth rate may be difficult to sustain
or increase. To the extent these trends continue, Network Associates' results of
operations could be materially adversely affected. Renewals have historically
accounted for a significant portion of Network Associates' net revenue; however,
there can be no assurance that Network Associates will be able to sustain
historic renewal rates for its products in the future. Risks related to Network
Associates' change in business strategies, including its newly introduced suite
pricing model and its development of a two-year subscription licensing model for
Network Associates' Sniffer products and a software only version of Network
Associates' Sniffer
                                       107
<PAGE>   108
 
products, could also cause fluctuations in Network Associates' operating results
and could make comparisons with historic operating results and balances
difficult. To more effectively service its customer's evolving needs, Network
Associates also intends to significantly expand and develop its worldwide
professional service organization.
 
     Although Network Associates believes that its products and systems are Year
2000 compliant, Network Associates' revenues and results of operations and
financial condition may be adversely impacted by, among other things, failure of
third party equipment and software utilized by Network Associates to be Year
2000 compliant and the potential adverse impact of Year 2000 compliance on its
customers purchasing patterns and availability of resources to acquire Company
products.
 
     International revenue accounted for approximately 32 per cent. and 27 per
cent. of net revenue for the three months ended 31 March 1998 and 1997,
respectively. The increase in international net revenue as a percentage of net
revenue was due primarily to increased acceptance of Network Associates'
products in international markets and the continued investment in international
operations. Network Associates also expects that a significant portion of such
international revenue will be denominated in local currencies. To reduce the
impact of foreign currency fluctuations, Network Associates uses non-leveraged
forward currency contracts. However, there can be no assurance that Network
Associates' 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 circumstances (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 affect on Network
Associates' future international license revenue. Further, in countries with a
high incidence of software piracy, Network Associates may experience a higher
rate of piracy of its products. There are a number of additional risks related
to the export from the United States of Network Associates' PGP and TIS security
products.
 
COST OF REVENUE
 
     Cost of revenue is comprised of cost of product revenue and cost of
services and support revenue. Cost of product revenue consists primarily of the
cost of media, manuals and packaging for products distributed through
traditional channels, royalties and, with respect to certain Sniffer products,
computer platforms and other hardware components. Cost of services and support
revenue consists principally of salaries and benefits related to employees
providing customer support and consulting and education services. Cost of
revenue increased 34 per cent. to U.S.$34.2 million in the three months ended 31
March 1998 from U.S.$25.5 million in the three months ended 31 March 1997. This
increase is due to an increase in net revenue (particularly product revenues) as
well as the initial investment in the anti-virus professional services
organization.
 
     Network Associates continues to expand its professional services
organization which is expected to cause the cost of services and support revenue
to increase in absolute dollars and may cause such expenses as a percentage of
net revenue to increase. To the extent that the percentage of Network
Associates' net revenue which is generated through traditional distribution
channels increases, Network Associates' cost of net revenue will increase and,
accordingly, gross margins will decrease. In addition, to the extent that
Network Associates increases its reliance on retail distribution, it may
encounter problems related to product returns and limited shelf space
availability. Network Associates is seeking to expand the breadth and depth of
its product suites.
 
                                       108
<PAGE>   109
 
RESEARCH AND DEVELOPMENT
 
     Research and development expenses consist primarily of salary and benefits
for Network Associates' development and technical support staff. Research and
development expenses increased 43 per cent. to U.S.$25.5 million in the three
months ended 31 March 1998 from U.S.$17.9 million in the three months ended 31
March 1997. This increase was primarily a result of the expansion of Network
Associates' product development and technical support staff and, to a lesser
extent, the increased use of independent contractors. As a percentage of net
revenue, research and development expenses increased to 14 per cent. in the
three months ended 31 March 1998 from 13 per cent. in the three months ended 31
March 1997.
 
     Network Associates believes that its ability to maintain its
competitiveness will depend in large part upon its ability to enhance existing
products, develop and acquire new products and develop and integrate acquired
products. The market for computer software is characterized by low barriers to
entry and rapid technological change, and is highly competitive with respect to
timely product introductions. The timing and amount of research and development
expenses may vary significantly based upon the number of new products and
significant upgrades under development and products acquired during a given
period.
 
MARKETING AND SALES
 
     Marketing and sales expenses consist primarily of salary, commissions and
benefits for marketing, sales and customer support personnel and costs
associated with advertising and promotions. Marketing and sales expenses
increased 39 per cent. to U.S.$56.6 million in the three months ended 31 March
1998 from U.S.$40.6 million in the three months ended 31 March 1997. This
increase was primarily the result of an increase in marketing and sales
personnel and, to a lesser extent, increased advertising and promotional
activities required to support increased sales volumes and expanding product
lines. As a percentage of net revenue, marketing and sales expense was 30 per
cent. in the three months ended 31 March 1998 and 29 per cent. in the three
months ended 31 March 1997.
 
GENERAL AND ADMINISTRATIVE
 
     General and administrative expenses consist principally of salary and
benefit costs for administrative personnel and general operating costs. General
and administrative costs increased 17 per cent. to U.S.$11.2 million in the
three months ended 31 March 1998 from U.S.$9.5 million in the three months ended
31 March 1997. The increase is largely a result of an increased staffing to
support operations both domestically and internationally and to accommodate the
growth in revenue. As a percentage of net revenue, general and administrative
expenses were 6 per cent. in the three months ended 31 March 1998 and 7 per
cent. in the three months ended 31 March 1997.
 
ACQUISITION AND OTHER RELATED COSTS
 
     In March 1997, Network Associates wrote off U.S.$19.5 million of acquired
in-process technology in connection with the acquisition of 3DV Technology, Inc.
 
     The software industry has experienced and is expected to continue to
experience a significant amount of consolidation. In addition, it is expected
that Network Associates 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. Network Associates
continually evaluates potential acquisitions of complementary businesses,
products and technologies. Any acquisition, depending on its size, could result
in the use of a significant portion of Network Associates' available cash or, if
such acquisition is made utilizing Network Associates' securities, could result
in significant dilution to Network Associates' stockholders, and could result in
the incurrence of significant acquisition related charges to earnings. For
example, in the three months ending 30 June 1998, Network Associates expects to
take significant acquisition related charges in
                                       109
<PAGE>   110
 
connection with the TIS and Magic Solutions acquisitions which were both
consummated in the second quarter ending 30 June 1998. Acquisitions by Network
Associates 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 Network Associates.
Furthermore, there can be no assurance that any products acquired in connection
with any acquisition will gain acceptance in Network Associates' markets or that
Network Associates will obtain the anticipated or desired benefits of such
transactions.
 
INTEREST AND OTHER INCOME AND EXPENSE, NET
 
     Interest and other income and expense increased to U.S.$4.8 million in the
three months ended 31 March 1998 from U.S.$2.9 million in the three months ended
31 March 1997. This increase was due to the investment of cash generated from
operating activities and the issuance, in February 1998, of debentures with net
proceeds of approximately U.S.$337.6 million. Interest expense increased to
U.S.$2.5 million in the three months ended 31 March 1998 from zero in the three
months ended 31 March 1997. Interest expense relates to the debentures issued in
February 1998.
 
PROVISION FOR INCOME TAXES
 
     Network Associates' effective tax rate was 36 per cent. and 57 per cent.
for the three months ended 31 March 1998 and 1997 respectively. Excluding the
one time charge for the write off of in-process research and development,
Network Associates' effective tax rate in the three months ended 31 March 1997
would have been 35 per cent.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At 31 March 1998, Network Associates had U.S.$191.0 million in cash and
cash equivalents and U.S.$591.5 million in marketable securities, for a combined
total of U.S.$782.5 million.
 
     Net cash provided by operating activities was U.S.$28.9 million and
U.S.$40.9 million in the three months ended 31 March 1998 and 1997 respectively.
Net cash provided by operating activities in the three months ended 31 March
1998 consisted primarily of net income and an increase in deferred revenue which
were offset primarily by an increase in accounts receivable, prepaid and other
assets and accounts payable and accrued liabilities. In the three months ended
31 March 1997, net cash provided by operating activities consisted primarily of
net income before acquisition costs, plus increases in deferred revenue and
prepaid and other assets, offset primarily by increases in accounts receivable
and deferred taxes.
 
     Network Associates expects its accounts receivable balance as a percentage
of sales to increase due to Network Associates' increased emphasis on
international sales (typically having longer payment terms) and Network
Associates' emphasis on licensing its network security and management product
suites to enterprise customers (which complex products may require longer
installation and implementation cycles, in turn resulting in potentially longer
payment cycles). Increased licensing through the indirect channel may also
impact Network Associates' receivable collection experience due to the longer
payment cycle for value added resellers ("VARs") and system integrators. To
address this increase in accounts receivable and to improve cash flow, Network
Associates may, among other things, take actions to encourage earlier payment of
receivables or sell receivables. To the extent that Network Associates'
receivable balance increases, Network Associates will be subject to greater
general credit risks with respect thereto.
 
     Net cash used in investing activities was U.S.$370.4 million and U.S.$27.3
million in the three months ended 31 March 1998 and 1997, respectively,
primarily reflecting purchases of marketable securities and additions to fixed
assets and intangible assets.
 
     Net cash provided by financing activities was U.S.$409.0 million in the
three months ended 31 March 1998, consisting primarily of net proceeds from the
issuance of the Debentures, and the
 
                                       110
<PAGE>   111
 
proceeds and tax benefits associated with the exercise of non-qualified stock
options. Net cash provided by financing activities was U.S.$12.0 million in the
three months ended 31 March 1997, consisting primarily of the proceeds and tax
benefits associated with the exercise of non-qualified stock options partially
offset by the repurchase of common stock under the Network General stock
repurchase program.

</TABLE>
 
NET REVENUE
 
     Net revenue increased 45 per cent. to U.S.$612.2 million in 1997 from
U.S.$421.8 million in 1996, and 51 per cent. from U.S.$278.9 million in 1995.
The increases in net revenue are due to the increases in product revenue and
services and support revenues described below.
 
     Product revenue increased 49 per cent. to U.S.$510.8 million from
U.S.$343.9 million in 1996, and 36 per cent. from U.S.$252.2 million in 1995.
The increase in the growth rate in product revenues was primarily due to
increases in the licensing of anti-virus software products to new customers,
renewing expiring anti-virus licenses, continued acceptance of Network
Associates' Sniffer products and continued acceptance of Network Associates'
consulting and support services. The increase is also attributable to a lesser
extent to the licensing of products (other than anti-virus and Sniffer products)
to new and existing customers as well as expansion into indirect product
distribution channels and international markets. Finally, changes in 1995 in
Network Associates' anti-virus revenue recognition described below contributed
to the increase in product revenue in both 1996 and 1995.
 
                                       111
<PAGE>   112
 
     Prior to 1 July 1995 revenue from subscription licenses for anti-virus
software was recognized ratably over a two year period as Network Associates did
not separately sell the product license and maintenance. Effective 1 July 1995,
Network Associates began to sell these components separately and currently
recognizes, upon the initial sale, 80 per cent. of the total fee as product
license revenue and defers 20 per cent. of the fee as maintenance. The
maintenance fee is recognized over the service period, generally two years.
 
     As a result of the change in revenue recognition for anti-virus licenses in
July 1995, period-to-period results are not directly comparable and should not
be relied upon as indicative of future performance. As a decreasing percentage
of Network Associates' net revenue is attributable to the recognition of
previously deferred anti-virus revenue, Network Associates' net revenue in
future periods may be subject to greater fluctuations. In addition to generating
net revenue through licenses, Network Associates sells certain of its network
security and management products with shrink-wrap licenses through traditional
distribution channels. Network Associates recognizes revenue from sales to
distributors upon shipment, subject to a reserve for returns.
 
     Service revenues increased 30 per cent. to U.S.$101.4 million in 1997 from
U.S.$77.9 million in 1996 which in turn increased 192 per cent. from U.S.$26.7
million in 1995. The increase in services and support revenues resulted from
growth in all categories of service revenues, principally due to the growth of
the installed customer base and the resulting renewal of maintenance contracts.
The high growth from 1995 to 1996 was due primarily to Network Associates
initiating consulting and support services relating to the anti-virus and
network security software products.
 
     International revenue accounted for approximately 28 per cent., 24 per
cent. and 25 per cent. of net revenue for 1997, 1996 and 1995, respectively. The
increase in international net revenue as a percentage of net revenue from 1996
to 1997 was due primarily to increased acceptance of Network Associates'
products in international markets and the continued investment in international
operations. The decrease from 1995 to 1996 was due primarily to domestic revenue
growing at a faster rate than international revenue.
 
COST OF REVENUE
 
     Cost of revenue increased 41 per cent. to U.S.$108.2 million in 1997 from
U.S.$76.9 million in 1996, which in turn increased by 58 per cent. from
U.S.$48.7 million in 1995. The increases in net revenue are due to the increases
in cost of product revenue and cost of services and support revenue described
below.
 
     Cost of product revenues increased 35 per cent. to U.S.$77.7 million in
1997 from U.S.$57.6 million in 1996. From 1995 to 1996 cost of product revenues
increased 52 per cent. from U.S.$37.9 million. The increase in cost of product
revenues from 1996 to 1997 was primarily due to a corresponding increase in
product revenues. The increase in cost of product revenues from 1995 to 1996 was
due to an increase in product revenues as well as the increase in sales of third
party computer platforms and other hardware components as part of certain
Sniffer products, which have a lower gross margin than Network Associates' other
products. As a percentage of net product revenue, cost of product revenue was 15
per cent. in 1997 and 17 per cent. in 1996 and 15 per cent. in 1995.
 
     In 1997, cost of services and support revenue increased 58 per cent. to
U.S.$30.5 million from U.S.$19.4 million in 1996. From 1995 to 1996, cost of
services and support revenues increased 78 per cent. from U.S.$10.8 million.
These increases are due to increases in net revenue as well as the initial
investment in the anti-virus professional services organization. Costs increased
at a higher rate than revenue due to the shift in the mix of support and
professional services revenue versus revenue from warranty and maintenance
contracts previously deferred. Costs of services and support revenue as a
percentage of net services and support revenue was 30 per cent. in 1997, 25 per
cent. in 1996 and 41 per cent. in 1995.

RESEARCH AND DEVELOPMENT
 
     Research and development expenses increased 63 per cent. to U.S.$85.0
million in 1997 from U.S.$52.2 million in 1996. From 1995 to 1996, research and
development expenses increased 42 per cent. from U.S.$36.8 million. These
increases were primarily a result of the expansion of Network Associates'
product development and technical support staff and, to a lesser extent, the
increased use of independent contractors. As a percentage of net revenue,
research and development expenses increased to 14 per cent. in 1997 from 12 per
cent. in 1996. Research and development spending decreased as a percentage of
net revenue in 1996 from 13 per cent. in 1995. Although in absolute dollars,
research and development spending increased, as a percentage of net revenue
research and development expenses decreased due to a higher rate of increase in
net revenue.
 
MARKETING AND SALES
 
     Marketing and sales expenses increased 48 per cent. to U.S.$181.0 million
in 1997 from U.S.$122.6 million in 1996. From 1995 to 1996, marketing and sales
expenses increased 33 per cent. from U.S.$92.3 million in 1995. These increases
were primarily the result of an increase in marketing and sales personnel and,
to a lesser extent, increased advertising and promotional activities required to
support increased sales volumes and expanding product lines. As a percentage of
net revenue, marketing and sales expense was 29 per cent. in 1997 and 1996 a
decrease from 33 per cent. in 1995. Although in absolute dollars, marketing and
sales spending increased from 1995 to 1996, as a percentage of net revenue these
expenses decreased due to a higher rate of growth in net revenue. Network
Associates is seeking to expand the breadth and depth of its product suites.
 
GENERAL AND ADMINISTRATIVE
 
     General and administrative costs increased 42 per cent. to U.S.$43.1
million in 1997 from U.S.$30.3 million in 1996. From 1995 to 1996, general and
administrative expenses increased 51 per cent. from U.S.$20.1 million. The
increase in 1997 is largely a result of a increased staffing to support
operations both domestically and internationally and to accommodate the growth
in revenue. As a percentage of net revenue, general and administrative expenses
were 7 per cent. in 1997, 1996 and 1995.
 
ACQUISITION AND OTHER RELATED COSTS
 
     In connection with the Network General merger, Network Associates incurred
direct transaction costs of approximately U.S.$15 million consisting of fees for
investment bankers, attorneys, accountants, financial printing and other related
charges. These costs have been charged to operations in December 1997. Network
Associates has also incurred restructuring charges of approximately U.S.$69.2
million in connection with the merger and the acquisitions of Helix software
company, Paradigm Agency Pty Ltd. and Pretty Good Privacy, Inc. ("PGP"). These
restructuring costs relate to the closure and elimination of duplicate leased
facilities, the write-off of inventory associated with duplicate and
discontinued product, repackaging of product, the write-off of impaired assets
and severance costs related to terminated employees. In addition, U.S.$18
million of restructuring costs relate to the write-off of contingent payments
associated with the acquisition of Cinco Networks, Inc. ("Cinco") by Network
General. Network Associates also wrote off U.S.$73.6 million of acquired
in-process research and development in 1997 in connection with the acquisitions
of PGP, Cinco and 3DV Technology, Inc. ("3DV").
 
     In 1996, Network Associates wrote off U.S.$19.5 million of acquired
in-process technology in connection with the acquisition of 3DV and also
expensed U.S.$9.0 million and U.S.$2.1 million in connection with the
acquisitions of Vycor and Interactive Distributed Systems Software GmbH,
respectively.
 
                                       113
<PAGE>   114
 
     In 1995, Network Associates wrote off U.S.$7.1 million of acquired
in-process technology in connection with the acquisition of AIM Technology and
expensed U.S.$6.8 million, U.S.$1.6 million and U.S.$2.5 million in connection
with the acquisitions of Saber, Assurdata and IPE, respectively. Also in 1995,
Network Associates expensed U.S.$1.9 million in connection with the acquisition
of distribution rights from three German distribution entities.
 
INTEREST AND MISCELLANEOUS INCOME
 
     Interest and miscellaneous income increased to U.S.$14.7 million in 1997
from U.S.$9.5 million in 1996 and U.S.$8.8 million in 1995. Interest and
miscellaneous income increased from 1996 to 1997 and from 1995 to 1996 due to
the investment of cash generated from operating activities.
 
PROVISION FOR INCOME TAXES
 
     Network Associates' effective tax rate for 1997, 1996 and 1995 was 186 per
cent. 44 per cent. and 38 per cent., respectively. Network Associates' effective
tax rate for 1997 and 1996 was 38 per cent. and 36 per cent. respectively,
excluding the effect of one-time non-deductible in-process research and
development, merger and other acquisition costs.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At 31 December 1997, Network Associates had U.S.$123.5 million in cash and
cash equivalents and U.S.$233.1 million in marketable securities, for a combined
total of U.S.$356.6 million.
 
     Net cash provided by operating activities was U.S.$90.7 million, U.S.$99.3
million and U.S.$50.4 million in 1997, 1996 and 1995, respectively. Net cash
provided by operating activities in 1997 consisted primarily of net income
before acquisition costs, plus increases in accounts payable and accrued
liabilities and deferred revenue which were offset primarily by an increase in
accounts receivable and deferred taxes. In 1996, net cash provided by operating
activities consisted primarily of net income plus accounts payable and accrued
liabilities which was offset primarily by increases in accounts receivable and
deferred taxes. In 1995, net cash provided by operating activities consisted
primarily of net income, accounts payable and accrued liabilities and deferred
revenue offset primarily by increases in accounts receivable and a decrease in
refundable income taxes.
 
     Net cash used in investing activities was U.S.$134.7 million, U.S.$58.9
million and U.S.$24.2 million in 1997, 1996 and 1995, respectively, primarily
reflecting investments in acquisitions and mergers, purchases of marketable
securities and additions to fixed assets and intangible assets.
 
     Net cash provided by financing activities was U.S.$43.4 million and
U.S.$20.2 million in 1997 and 1996 consisting primarily of the proceeds and tax
benefits associated with the exercise of non-qualified stock options. Net cash
used in financing activities in 1995 was U.S.$1.2 million consisting primarily
of the repurchase of common stock offset by the tax benefits associated with the
exercise of non-qualified stock options.

                                   APPENDIX 6
 
               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
 
     The following unaudited pro forma combined condensed financial statements
have been prepared to give pro forma effect to the Acquisition using the pooling
of interests method of accounting. All amounts are presented in U.S. dollars.
 
     The unaudited pro forma combined condensed financial statements reflect
certain assumptions deemed probable by Network Associates' management regarding
the Acquisition (for example, share information used in the unaudited pro forma
information approximates actual share information at the Effective Date). No
adjustments to the unaudited pro forma combined condensed financial information
have been made to account for different possible results in connection with the
foregoing, as Network Associates' management believes that the impact on such
information of the varying outcomes, individually or in the aggregate, would not
be materially different.
 
     The unaudited pro forma combined condensed balance sheet as of 31 March
1998 gives effect to the Acquisition as if it had occurred on 31 March 1998, and
combines the unaudited consolidated balance sheet of Network Associates as of 31
March 1998 and the unaudited consolidated balance sheet of Dr Solomon's as of 28
February 1998. The unaudited pro forma combined statements of operations for
each of the three years in the period ended 31 December 1997 and the three month
periods ended 31 March 1997 and 1998 have been prepared from the historical
financial statements of Network Associates and Dr Solomon's, and give effect to
the Acquisition as if it had occurred on 1 January 1995. Dr Solomon's fiscal
year ends 31 May. Dr Solomon's plans to change its year end to 31 December,
effective with the closing of the Acquisition. The pro forma statements of
operations for the years ended 31 December 1995, 1996 and 1997 reflect the
statements of operations of Network Associates for the years ended 31 December
1995, 1996 and 1997, respectively, and the profit and loss accounts of Dr
Solomon's based on the aggregation of unaudited quarterly financial information
for each of the years ended 30 November 1995, 1996 and 1997, respectively. The
pro forma statements of operations for the three months ended 31 March 1997 and
1998 reflect the statements of operations of Network Associates for the three
months ended 31 March 1997 and 1998, respectively, and the profit and loss
accounts of Dr. Solomon's for the three months ended 28 February 1997 and 1998.
 
     Network Associates and Dr Solomon's estimate that they will incur direct
transaction costs of approximately $18 million associated with the Acquisition,
consisting of transaction fees for investment bankers, attorneys, accountants,
financial printing and other related charges. These transactions costs will be
charged to operations upon consummation of the Acquisition. The combined company
will incur an additional significant charge to operations, which is not
currently reasonably estimable, to reflect costs associated with integrating the
two companies. This charge has not been reflected in the pro forma condensed
balance sheet or pro forma condensed statements of operations. There can be no
assurance that the combined company will not incur additional charges to reflect
costs associated with the Acquisition or that management will be successful in
its efforts to integrate the operations of the two companies.
 
     The financial information of Dr Solomon's included in these pro forma
condensed financial statements has been derived from the historical financial
statements of Dr Solomon's prepared in accordance with U.K. GAAP and stated in
pounds sterling. U.K. GAAP and U.S. GAAP differ in certain significant respects
which are described in the Notes to the Financial Statements of Dr Solomon's
included at Part B of Appendix 2. These financial statements have been adjusted
to comply with U.S. GAAP and have been translated to U.S. dollars at the rate of
$1.65 per pound sterling in the unaudited pro forma condensed combined balance
sheet as of 31 March 1998, and at the rates of $1.58, $1.56, $1.65 per pound
sterling for the years ended 31 December 1995, 1996 and 1997, respectively, and
at the rates of $1.65 and $1.64 per pound sterling for the three month periods
ended 31 March 1997 and 1998, respectively, in the pro forma combined condensed
statements of operations. Such translations should not be construed as
representations that the
                                       115
<PAGE>   116
 
pound sterling amounts represent, or have been, or could be converted into U.S.
dollars at that or any other rate. Certain reclassifications have been made to
Dr Solomon's financial statements included in these pro forma financial
statements to conform to Network Associates' presentation.
 
     The following unaudited pro forma combined consolidated financial
information is presented for illustrative purposes only and is not necessarily
indicative of the financial position or results of operations that would have
actually been reported had the Acquisition occurred at the beginning of the
periods presented, nor is it necessarily indicative of future financial position
or results of operations. These unaudited pro forma combined financial
statements are based upon, and should be read in conjunction with, the
respective historical consolidated financial statements and notes thereto of Dr
Solomon's and Network Associates included in this document at Part B of Appendix
2 and Part B of Appendix 3, respectively, and do not incorporate, nor do they
assume any benefits from cost savings or synergies of operations of the combined
companies.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
(1)  PRO FORMA BASIS OF PRESENTATION
 
     The unaudited pro forma combined financial statements for the years ended
31 December 1995, 1996 and 1997 reflect the combination of the financial
statements of Network Associates for the years ended 31 December 1995, 1996 and
1997 and the aggregation of unaudited quarterly financial statements of Dr
Solomon's for the years ended 31 November 1995, 1996 and 1997. The unaudited pro
forma combined statements of operations for the three month periods ended 31
March 1997 and 1998 reflect the combination of the statements of operations of
Network Associates for the three months ended 31 March 1997 and 1998 and the
statements of operations of Dr Solomon's for the three months ended 28 February
1997 and 1998.
 
     These unaudited pro forma combined financial statements reflect the
issuance of 15,279,387 shares of Network Associates Common Stock in exchange for
an aggregate of 55,310,000 Dr Solomon's Ordinary Shares (in issue as of 31 May
1998) in connection with the Acquisition, based on the Exchange Ratio of 0.27625
per Dr Solomon's Ordinary Share (or 0.82875 per Dr Solomon's ADS) set forth in
the following table:
 
<TABLE>
<S>                                                           <C>
Dr Solomon's Ordinary Shares in issue as of 31 May 1998.....    55,310,000
Exchange Ratio..............................................   0.27625:1.0
Number of Shares of Network Associates Common Stock
  exchanged.................................................    15,279,387
Number of shares of Network Associates Common Stock
  outstanding at 31 May 1998................................   115,053,768
                                                              ------------
Number of shares of Network Associates Common Stock
  outstanding after the completion of the Acquisition.......   130,333,155
                                                              ============
</TABLE>
 
     The actual number of Network Associates Common Stock to be issued will be
determined on the Effective Date based on the number of Dr Solomon's Ordinary
Shares in issue at that date.
 
(2)  PRO FORMA COMBINED BALANCE SHEET
 
     (a) Network Associates and Dr Solomon's estimate that they will incur
direct transaction costs of approximately $18 million associated with the
Acquisition, consisting of transaction fees for investment bankers, attorneys,
accountants, financial printing and other related charges. These transaction
costs will be charged to operations upon consummation of the Acquisition. These
charges have been reflected in the unaudited pro forma combined balance sheet
but have not been included in the unaudited pro forma combined statements of
operations.
 
     (b) It is expected that following the Acquisition, Network Associates will
incur an additional significant charge to operations, which is not currently
reasonably estimable, to reflect costs associated with integrating the two
companies. This charge has not been reflected in the pro forma condensed balance
sheet or condensed statement of operations. There can be no assurance that the
combined company will not incur additional charges to reflect costs associated
with the Acquisition or that the combined companies' management will be
successful in its efforts to integrate the operations of the two companies.

                                  RISK FACTORS
 
     The following factors should be considered carefully by holders of Dr
Solomon's Shares in evaluating whether to approve the Acquisition and the
Scheme. These factors should be considered in conjunction with the other
information included in this document.
 
RISKS RELATED TO THE ACQUISITION
 
     DIFFICULTIES OF INTEGRATING TWO COMPANIES. The successful combination of
Network Associates and Dr Solomon's will require substantial attention from
management. The anticipated benefits of the Acquisition will not be achieved
unless the operations of Dr Solomon's are successfully combined with those of
Network Associates in a timely manner. The difficulties of assimilation may be
increased by the need to integrate personnel and to combine different corporate
cultures and by Network Associates' limited personnel, management and other
resources. The successful combination of the two companies will also require
integration of the companies' product offerings, the coordination of their
research and development and sales and marketing efforts and managing a more
geographically diverse business. Shortly after the Acquisition, Network
Associates intends to incorporate Dr Solomon's Anti-Virus Toolkit as part of its
enterprise security suites. To do so will require significant engineering and
product integration and related expense. There can be no assurance as to how
long this process will take to complete or the amount of the related expense.
The process of combining the two organizations could cause the interruption of,
or a loss of momentum in, the activities of either or both of the companies'
businesses. It is expected that the announcement and pendency of the Acquisition
will cause certain customers to defer or alter purchasing decisions. The
diversion of management's attention from the day-to-day operations of Network
Associates, or difficulties encountered in the transition and integration
process, could have a material adverse effect on the business, financial
condition and results of operations of Network Associates. The difficulties of
integrating Network Associates and Dr Solomon's may also be compounded by
Network Associates' recent acquisitions of Magic Solutions and TIS or, subject
to the limitations set out in the Transaction Agreement, any other acquisition
transaction Network Associates may enter into.
 
     In addition, as a cross-border acquisition, the Acquisition entails certain
risks in addition to those normally encountered in a domestic acquisition. These
include the difficulty of integrating employees from a different culture into
the acquiring organization; the need to understand the different incentives that
motivate employees in a non-U.S. company; the greater difficulty of implanting
the acquiring company's "corporate culture" in an organization that is
physically distant; and the difficulty and expense of relocating employees from
one country to another in the event of an internal group restructuring following
an acquisition. These factors can reduce the likelihood of the long-term success
of a cross-border acquisition, as employees of the acquired company may become
disenchanted with the acquiring company and terminate their employment. Network
Associates has never made an acquisition of a company of Dr Solomon's size whose
headquarters and principal operations are outside the United States. Although
Network Associates derives a substantial portion of its revenues from non-U.S.
sales, it has little experience integrating the management, sales, product
development and marketing organizations of a significant non-U.S. business with
its existing operations. Although Dr Solomon's has sales and marketing
operations in the United States and derives a significant portion of its revenue
from U.S. sales, its management and product development personnel are
predominantly based in the United Kingdom, and it derives a substantial portion
of its revenues from sales and services in Europe. There can be no assurance
that Network Associates will be able to successfully integrate the personnel and
operations of Dr Solomon's into the existing Network Associates organization.
 
     RISKS ASSOCIATED WITH FIXED EXCHANGE RATIO. As a result of the Acquisition,
each outstanding Dr Solomon's Ordinary Share and each outstanding Dr Solomon's
ADS (representing three
 
                                       122
<PAGE>   123
 
Dr Solomon's Ordinary Shares) will be converted into the right to receive
0.27625 and 0.82875, respectively, of a share of Network Associates Common
Stock. Because the exchange ratio is fixed, it will not increase or decrease due
to fluctuations in the market price of either Network Associates Common Stock or
Dr Solomon's ADSs (which are traded on EASDAQ and NASDAQ). The market value of
the consideration to be received by Dr Solomon's Shareholders in the Acquisition
will, therefore, depend on the market price of Network Associates Common Stock
on and after the Effective Date. In the event that the market price of Network
Associates Common Stock decreases or increases prior to the Effective Date, the
market value of Network Associates Common Stock to be received by Dr Solomon's
Shareholders in the Acquisition would correspondingly decrease or increase. The
market prices of Network Associates Common Stock and Dr Solomon's ADSs are set
out under the heading Market Quotations in Appendix 11 of this document. Dr
Solomon's Shareholders should obtain recent market quotations for Network
Associates Common Stock and Dr Solomon's ADSs. Network Associates Common Stock
and Dr Solomon's ADSs historically have been subject to substantial price
volatility. No assurance can be given as to the market prices of Network
Associates Common Stock or Dr Solomon's ADSs at any time before the Effective
Date or as to the market price of the Network Associates Common Stock at any
time thereafter.
 
     SUBSTANTIAL EXPENSES RESULTING FROM THE ACQUISITION. The negotiation and
implementation of the Acquisition will result in significant pre-tax expenses to
Network Associates and Dr Solomon's. Excluding costs associated with combining
the operations of the two companies, pre-tax expenses are estimated at
approximately $18 million, primarily consisting of fees for investment bankers,
attorneys, accountants, financial printing and other related charges. There can
be no assurance as to the aggregate amount of such expenses or that
unanticipated contingencies will not occur that will substantially increase the
costs of combining the operations of the two companies.
 
     POTENTIAL DILUTIVE EFFECT TO STOCKHOLDERS.  Although Network Associates
believes that beneficial synergies will result from the Acquisition, there can
be no assurance that combining the two companies' businesses, even if achieved
in an efficient, effective and timely manner, will result in combined results of
operations and financial condition superior to what would have been achieved by
each company independently, or as to the period of time required to achieve such
result. The issuance of new Network Associates Common Stock in connection with
the Acquisition will have the effect of reducing Network Associates' net income
per share and could reduce the market price of the Network Associates Common
Stock unless and until revenue growth or cost savings and other business
synergies sufficient to offset the effect of such issuance can be achieved.
There can be no assurance that holders of Dr Solomon's Shares would not achieve
greater returns on investment if Dr Solomon's were to remain an independent
company.
 
     DEPENDENCE ON KEY PERSONNEL.  Network Associates' future success after the
Acquisition depends in significant part upon the continued service of Dr
Solomon's key technical, sales and senior management personnel. The loss of the
services of one or more of these key employees could have a material adverse
effect on Network Associates' business and operating results. Additions of new
and departures of existing personnel, particularly in key positions, can be
disruptive and can result in departures of other existing personnel. As a result
of the Acquisition, and pursuant to the terms of Dr Solomon's Share Option
Schemes, the exercisability of outstanding options under such option schemes
will accelerate in full. Such acceleration, taken in conjunction with the
nominal exercise price payable in connection with a significant majority of
these options, may reduce the incentive for a significant number of Dr Solomon's
employees to remain with Network Associates after the Acquisition.
 
RISKS RELATED TO BUSINESS AND OPERATIONS
 
     VARIABILITY OF QUARTERLY OPERATING RESULTS. Each of Network Associates' and
Dr Solomon's results of operations have been subject to significant
fluctuations, particularly on a quarterly basis,
 
                                       123
<PAGE>   124
 
and their future results of operations could fluctuate significantly from
quarter to quarter and from year to year.
 
     Network Associates' and Dr Solomon's net revenues and operating results may
vary from quarter to quarter due to a number of reasons, including (i) the
volume and timing of new orders and renewals, (ii) distributor inventory levels
and return rates; (iii) changes in the proportion of revenues attributable to
licenses and consulting fees; (iv) the introduction of new products, product
upgrades or updates by it or its competitors; (v) changes in product mix; (vi)
changes in product prices and pricing models; (vii) seasonality; (viii) trends
in the computer industry; (ix) general economic conditions (such as the recent
economic turbulence in Asia); (x) extraordinary events such as acquisitions or
litigation; and (xi) the occurrence of unexpected events. The operating results
of many software companies reflect seasonal trends, and Network Associates' and
Dr Solomon'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 Network Associates has experienced significant growth in net
revenue and net income (before acquisition and other related costs) in absolute
terms, Network Associates' growth rate has slowed in recent periods. Network
Associates has experienced increased price competition for its products and
Network Associates expects competition to increase in the near-term, which may
result in reduced average selling prices for Network Associates' products in the
future. Due to these and other factors (such as a maturing anti-virus industry
and an increasingly higher base from which to grow), Network Associates'
historic revenue growth rate will be difficult to sustain or increase. To the
extent these trends continue, Network Associates' results of operations could be
materially adversely affected. Renewals have historically accounted for a
significant portion of Network Associates' net revenue; however, there can be no
assurance that Network Associates will be able to sustain historic renewal rates
for its products in the future. Risks related to Network Associates' 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.
 
     The timing and amount of Network Associates' and Dr Solomon's revenues are
subject to a number of factors that make estimating operating results prior to
the end of a quarter uncertain. Neither Network Associates nor Dr Solomon's
expects to maintain a significant level of backlog and, as a result, product
revenues in any quarter will be dependent on contracts entered into or orders
booked and shipped in that quarter. During 1997, Network Associates generally
experienced a significant level of order receipts toward the end of the last
month of a quarter, resulting in a high percentage of revenue shipments during
the last month of a quarter, which makes predicting revenues more difficult. The
timing of closing larger orders increases the risks of quarter-to-quarter
fluctuation. In addition, to the extent that Network Associates 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, operating results for that quarter could be
materially adversely affected.
 
     The trading prices of Network Associates Common Stock and Dr Solomon's ADSs
have 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 Network Associates' Common Stock. Network Associates 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
Network Associates Common Stock.
 
                                       124
<PAGE>   125
 
     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 Network
Associates' and Dr Solomon's products as standard features of computer hardware
or of operating system software or other software could render Network
Associates' and Dr Solomon's products obsolete and unmarketable, particularly if
the quality of such functionality were comparable to that of Network Associates'
or Dr Solomon's products. Furthermore, even if 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 Network
Associates' or Dr Solomon'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 Network Associates or Dr Solomon's,
as applicable, 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, their business, financial condition and
results of operations would be materially adversely affected.
 
     NATURE OF VIRUSES. Many computer viruses are designed to circumvent
anti-virus protection devices and sabotage computer systems. Accordingly,
Network Associates and Dr Solomon's products are under constant attack by new
and increasingly sophisticated types of viruses. There can be no assurance that
Network Associates or Dr Solomon's will be able to respond effectively to any
new viruses or that demand for their respective products will not suffer if they
are unable to do so. In addition, there can be no assurance that diskettes
containing their respective software will not become infected by viruses despite
constant vigilance in this regard. Anti-virus software products are attractive
as candidates for carriers of computer viruses.
 
     RISKS ASSOCIATED WITH NETWORK ASSOCIATES' ACQUISITIONS. Network Associates
faces significant risks associated with its recent combination with Network
General and other recent acquisitions (including the acquisitions of PGP and
Helix in December 1997, the acquisitions of Magic Solutions and TIS in April
1998 and the acquisition of Secure Networks, Inc. in May 1998). There can be no
assurance that Network Associates will realize the desired benefits of these
transactions. In order to successfully integrate these companies, Network
Associates 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, Secure's security auditing products, Magic Solutions' helpdesk
software and TIS's firewall and intrusion detection software) 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 Network Associates, or difficulties
encountered in the integration process, could have a material adverse effect on
Network Associates' business, financial condition and results of operations.
 
     During 1997, Network Associates incurred significant non-recurring charges
associated with Network General combination and the acquisitions of PGP and
Helix. During the second quarter of 1998, Network Associates expects to incur
significant non-recurring charges associated with the acquisition of Magic and
TIS. There can be no assurance that Network Associates will not incur additional
material charges in subsequent quarters to reflect additional costs associated
with these
 
                                       125
<PAGE>   126
 
transactions and with respect to its name change and the marketing of its
products under the "Network Associates" name.
 
     In addition to its recent acquisitions, Network Associates has consummated
a series of significant additional acquisitions since 1994, including its
international distributors in Australia, Finland, Brazil, Japan and The
Netherlands. 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 Network Associates' available cash or, if such
acquisition is made utilizing Network Associates' securities, could result in
significant dilution to Network Associates' stockholders, and could result in
the incurrence of significant acquisition related charges to earnings.
Acquisitions by Network Associates 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
Network Associates. Furthermore, there can be no assurance that any products
acquired in connection with any such acquisition will gain acceptance in Network
Associates' markets or that Network Associates will obtain the anticipated or
desired benefits of such transactions.
 
     The software industry has experienced and is expected to continue to
experience a significant amount of consolidation. In addition, it is expected
that Network Associates 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. Network Associates
continually evaluates potential acquisitions of complementary businesses,
products and technologies, and it is expected that Network Associates will
continue to grow through such strategic acquisitions in order, among other
things, to expand the breadth and depth of its product suites and to build its
professional services organization. Subject to certain provisions of the
Transaction Agreement, prior to the Effective Date, Network Associates may enter
into agreements or negotiations with respect to one or more acquisitions of
other businesses, products and/or technologies. Consequently, Network Associates
expects that acquisition risks of the type mentioned above will continue in the
future.
 
     RISKS ASSOCIATED WITH FAILURE TO MANAGE GROWTH -- NETWORK
ASSOCIATES. Network Associates' 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, Network Associates' ability to manage any growth, particularly with
the anticipated expansion of Network Associates' 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 Network
Associates' business, financial condition and results of operations.
 
     RISKS RELATED TO CERTAIN NETWORK ASSOCIATES BUSINESS STRATEGIES. Network
Associates has historically derived a significant majority of its revenues from
the licensing of its flagship anti-virus products and Sniffer products. See the
section headed "Network Associates, dependence on Revenue from Flagship
Anti-Virus and Sniffer Products" below. Network Associates 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, Network Associates
recently organized its products into four product suites: McAfee Total Virus
Defense, PGP Total Network Security, and Sniffer Total Network Visibility and
McAfee Total Service Desk. These four product suites together form an 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 Network Associates' operating results. Although Network
Associates 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
                                       126
<PAGE>   127
 
an effort to increase total Sniffer unit sales Network Associates intends to
develop software only versions of certain Sniffer products meaning that Network
Associates would no longer sell the hardware components contained in the current
Sniffer products. There can be no assurance that Network Associates can produce
a software only Sniffer product on a timely basis or at all, that customers will
not continue to require that Network Associates 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, Network Associates' operating results
and financial condition would likely be affected. In the case of subscription
licenses, Network Associates 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 Network Associates' 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, Network Associates would expect lower total revenues and
a higher overall gross margin related to the transaction, as Network Associates
would not be selling the corresponding hardware component. Currently, the
hardware component has a lower gross margin than the total product gross margin.
 
     As part of the Net Tools concept, Network Associates 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. Network
Associates faces significant engineering challenges related to these efforts. In
addition, Network Associates faces significant engineering and other challenges
related to the integration of its various security products (such as its
recently acquired PGP encryption products, Network General CyberCop product,
Magic Solutions' helpdesk products, TIS firewall and intrusion detection
products and any products acquired in the Acquisition) into a marketable suite
of products and the development of a software only Sniffer product. Success of
Network Associates' Net Tools suite strategy will also depend, in part, upon
successful development and coordination of Network Associates' sales force; on
successful development of a national accounts sales force and an effective
indirect sales channel for Network Associates' Sniffer product and security
products; and on the development and expansion of an effective professional
services organization.
 
     The foregoing factors, individually or in the aggregate, could materially
adversely affect Network Associates' operating results and could make comparison
of historic operating results and balances difficult or not meaningful.
 
     RAPID TECHNOLOGICAL CHANGE; RISKS ASSOCIATED WITH PRODUCT
DEVELOPMENT -- NETWORK ASSOCIATES. 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. Network
Associates' 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 Network Associates believes that it offers one of the
broadest product lines in 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, Network Associates believes
that it will need to further expand its product offerings. There can be no
assurance that Network Associates will be successful in developing and
marketing, on a timely basis, enhancements to its existing products 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, Network Associates 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, Network Associates' existing
 
                                       127
<PAGE>   128
 
products and to cause customers to defer or cancel purchases of Network
Associates' existing products.
 
     Network Associates has in the past experienced delays in software
development, and there can be no assurance that Network Associates will not
experience delays in connection with its current or future product development
activities. Complex software products such as those offered by Network
Associates 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, Network Associates
experienced compatibility issues in connection with its recent NetShield
upgrade, and Network Associates' anti-virus software products have in the past
falsely detected viruses that did not actually exist. Delays and difficulties
associated with new product introductions, performance or enhancements could
have a material adverse effect on Network Associates' business, financial
condition and results of operation.
 
     Network Associates' 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, Network Associates 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, Network Associates' 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 Network Associates' products to
comply, or delays in compliance, with existing or evolving industry standards
could have a material adverse effect on Network Associates' business, financial
condition and results of operation.
 
     Network Associates' 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. Network Associates 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 Network Associates' business,
financial condition and results of operations. There can be no assurance that
Network Associates 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 Network Associates' 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 Network Associates' future products and
product versions which are designed to operate with such future versions of
operating systems. Network Associates' 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
Network Associates' business, financial condition and results of operations.
 
     There can be no assurance that (i) Network Associates will be able to
counter challenges to its current products; (ii) Network Associates' future
product offerings will keep pace with the technological changes implemented by
competitors or persons seeking to breach information security; (iii) Network
Associates' products will satisfy evolving preferences of customers and
prospects; or (iv) Network Associates will be successful in developing and
marketing products for any future technology. Failure to develop and introduce
new products and product enhancements in a timely fashion could have a material
adverse effect on Network Associates' financial condition or results of
operations.

     RAPID TECHNOLOGICAL CHANGE; FREQUENT PRODUCT ENHANCEMENTS; RISKS OF PRODUCT
DEFECTS -- DR SOLOMON'S. The markets for Dr Solomon's software products are
characterized by rapid technological advances, evolving industry standards in
computer hardware and software technology, changes in customer requirements and
frequent new product introductions and enhancements. As a result, Dr Solomon's
future success will depend upon its ability to continue to update its product
line on a timely basis and to develop and introduce new product features and
enhancements that keep pace with technological developments and new competitive
product offerings, satisfy increasingly sophisticated customer requirements and
achieve market acceptance. In particular, Dr Solomon's must continue to
anticipate and respond adequately to the development and proliferation of new
computer viruses and to advances in personal computer operating systems. There
can be no assurance that Dr Solomon's will be successful in developing and
marketing, on a timely and cost-effective basis, fully functional product
enhancements that respond to such factors and achieve market acceptance. Any
failure by Dr Solomon's to respond adequately to new virus threats or changing
market conditions, or significant delays in product development or introduction,
could have a material adverse effect on Dr Solomon's.
 
     Dr Solomon's estimates that the number of computer viruses is currently
increasing at an average rate of more than 200 new viruses per month. To respond
to new viruses Dr Solomon's updates nearly all of its anti-virus software
products at least monthly. This monthly updating process requires significant
software development and distribution resources. Dr Solomon's believes that it
is now possible for virus authors to generate easily vast numbers of new viruses
and to multiply quickly the size of the current virus population. Macro viruses,
in particular, are generally easier to write than other types of viruses and can
generally be written and distributed by users of common application software
packages. If this were to occur over a relatively short time period Dr Solomon's
would likely be required to deploy additional resources to disassemble these
viruses, which might not be offset by a corresponding increase in revenues. In
addition, significant growth in the virus threat could lead to requirements to
deploy additional technical support personnel. In these respects, there can be
no assurance that Dr Solomon's would be able to respond adequately to such a
large number of new viruses. In addition, a large increase in the number of new
viruses could result in the Toolkit requiring significantly greater memory space
on a user's PC or network and requiring several diskettes for distribution and
installation. It is also possible that virus authors could develop virus
techniques that would neutralise or render ineffective anti-virus technologies
currently being used by the Toolkit. Although it is likely that other anti-virus
software vendors would also face similar problems, it is possible that virus
authors could produce viruses targeted to avoid detection by the Toolkit or that
new viruses could be detected by competitive products but not by the Toolkit.
 
     In addition, software programs as complex as those offered by Dr Solomon's
may contain undetected errors or "bugs" when new versions are released which,
despite testing by Dr Solomon's, are discovered only after a product has been
installed and used by customers. For example, because of its strong sense of
obligation to customers, during 1996, Dr Solomon's sent six letters to its
customers warning of serious bugs, in one case resulting in a product recall
from distributors. In 1997, there were various problems associated with the
NetWare Toolkit which resulted in Dr Solomon's assisting customers to recover
lost data.
 
     Dr Solomon's believes that these incidences have been satisfactorily
resolved. However, there can be no assurance that, despite the testing carried
out by Dr Solomon's errors will not be found in Dr Solomon's products. The
occurrence of errors could result in adverse publicity, loss of or delay in
market acceptance or claims by customers against Dr Solomon's, any of which
could have a material adverse effect on Dr Solomon's.
 
     In addition, from time to time, Dr Solomon's issues significant new
releases of its software products to improve performance and enhance
functionality and ease of use. As a result of the complexities inherent in
anti-virus software and the broad functionality and performance demanded by
customers, major new product enhancements can require long development and
testing periods to achieve market acceptance. While Dr Solomon's has on occasion
experienced delays in the
                                       129
<PAGE>   130
 
scheduled introduction of new and enhanced products, to date Dr Solomon's
business has not been materially adversely affected by the release of products
containing errors.
 
     DEPENDENCE ON REVENUE FROM FLAGSHIP ANTI-VIRUS AND SNIFFER PRODUCTS. In
recent years, Network Associates has derived a substantial majority of its net
revenue from its flagship McAfee anti-virus software products and Sniffer
network fault and performance management products. 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 Network Associates' 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 Network Associates' business, financial condition and results of operations.
 
     DEPENDENCE ON EMERGENCE OF NETWORK MANAGEMENT AND NETWORK SECURITY
MARKETS. The markets for Network Associates' network management and network
security products and Dr Solomon's network security products are evolving, and
their growth depends upon broader market acceptance of network management and
network security software. Although the number of LAN-attached personal
computers has increased dramatically, 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 Network Associates or Dr Solomon's 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 or hardware. Therefore, even if network
management and network security tools gain broader market acceptance, there can
be no assurance that Network Associates' or Dr Solomon's products will be chosen
by organisations which acquire network management and network security tools.
Furthermore, to the extent that either network management or network security
market does continue to develop, Network Associates and Dr Solomon's expect that
competition will increase.
 
     COMPETITION -- NETWORK ASSOCIATES. The markets for Network Associates'
products are intensely competitive and Network Associates expects competition to
increase in the near-term. Network Associates 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, Network Associates' reputation and price. Certain of the
criteria upon which the performance and quality of Network Associates'
anti-virus software products compete include the number and types of viruses
detected, global distribution, breadth of product lines, the speed at which the
products run and ease of use. Certain of Network Associates' competitors have
been in Network management market longer than Network Associates, 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 Network Associates.
Network Associates will also need to develop name recognition for its new name,
"Network Associates." In addition, certain larger competitors such as Intel,
Microsoft and 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, Network Associates 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 Network
Associates' business, financial condition and results of operations. In
addition, competitive pressures may make it difficult for Network Associates to
maintain or exceed its growth rate.
 
                                       130
<PAGE>   131
 
     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. Network Associates' principal competitor is the Peter
Norton Group of Symantec in the network security market and Intel's LanDesk in
the network management market. Network Associates' other competitors include
Computer Associates/Cheyenne Software, IBM, Microsoft, Seagate 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 of the security industry, Network
Associates' principal competitors are Security Dynamics Technologies, Inc.
("SDTI"), Cylink Corporation, Entrust Technologies and VeriSign, Inc. Network
Associates' principal competitors in the help desk area are Remedy Corporation
and Software Artistry (recently acquired by Tivoli Systems/IBM). Network
Associates' principal competitor in the software-based network fault and
performance management area is HP, with other competitors including Azure
Technologies Incorporated, Concord Communications, DeskTalk Systems, Kaspia
Systems, Shomiti Systems, Inc. and Wandel & Goltermann, Inc. Network Associates
also faces competition in the security industry from Checkpoint Software, Cisco,
SDTI, Microsoft and other vendors in the encryption/firewall area. In addition,
Network Associates 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, Network Associates 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
industry around a smaller number of vendors who are able to provide the
necessary software and support capabilities. In addition, to the extent that
Network Associates is successful in developing its Net Tools suite of products
designed around a centralized management and administration console for the
Windows NT platform, Network Associates will likely compete with large computer
systems management companies such as IBM's Tivoli Systems (TME) and Computer
Associates (Unicenter). There can be no assurance that Network Associates 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 Network Associates. 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 Network
Associates 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 often 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 Network Associates will be able to compete successfully in international
markets.
 
     COMPETITION -- DR SOLOMON'S. The markets for Dr Solomon's products are
highly competitive and are characterized by constant pressures to update and
enhance Dr Solomon's products to identify and eradicate recently discovered
viruses, to optimize product performance and improve ease of use and to
incorporate new product features and product enhancements. Dr Solomon's primary
competitor is Symantec, vendor of the Norton line of anti-virus software
products. Other direct competitors include both smaller companies such as AVP,
Command Software, FRISK, Norman Data, Sophos and Trend Micro, and divisions of
larger companies such as Computer Associates, Intel Corporation, IBM and
Microsoft. In addition, in the future, vendors of computer hardware, operating
systems or other software products may enhance their products to include
functionality that is currently only provided by anti-virus software utility
products.
 
                                       131
<PAGE>   132
 
     Alternatively, changes in the design of computer hardware or operating
systems could render computers more immune to the threats posed by viruses. In
addition, the personal computer software market has historically been
characterized by low financial barriers to entry.
 
     Many of Dr Solomon's competitors have longer operating histories, greater
name recognition, broader product lines, access to larger customer bases and
significantly greater financial, technical, marketing, distribution and other
resources than Dr Solomon's. As a result, they may be able to adapt more quickly
to new or emerging technologies and changes in customer requirements or to
devote greater resources to the promotion and sale of their products than Dr
Solomon's. Certain of Dr Solomon's competitors have more diversified product
lines than Dr Solomon's and, therefore, may be able to withstand better any
downturns in the anti-virus software market. Dr Solomon's believes that its
primary competitor, Symantec, recently has been allocating greater resources to
the development of their anti-virus businesses. In addition, certain of Dr
Solomon's competitors may determine, for strategic reasons, to consolidate,
substantially lower the price of their anti-virus software products or bundle
their products with other products, such as hardware products or other software
products. In addition, current or potential competitors may establish financial
or strategic relationships among themselves or with current or potential
customers, resellers or other third parties. For example, IBM and Symantec
recently announced that IBM will resell Symantec's anti-virus products.
Accordingly, it is possible that new competitors or alliances among competitors
may emerge and rapidly acquire significant market share, particularly if large
computer software companies with substantial financial and marketing resources
obtain access to anti-virus software technologies by acquiring smaller
anti-virus software companies.
 
     Internationally, Dr Solomon's operates through 60 international partners
who act as distributors or republishers in those territories where Dr Solomon's
does not have direct operations. It is possible that competitors could acquire
these partners. Such acquisitions may result in the loss of business in that
territory and in additional costs in establishing a new partnership and in
defending the existing business.
 
     There can be no assurance that Dr Solomon's will be able to compete
successfully against current or future competitors or that competitive pressures
faced by Dr Solomon's will not have a material adverse effect on Dr Solomon's.
Dr Solomon's believes that the principal competitive factors in the anti-virus
software market are product performance (the number and types of viruses that
can be detected, the rate of false alarms, speed of operation, and obtrusiveness
in use of system memory and other scarce system resources), price, product
features, breadth of product line, ease of use, customer service and technical
support, supplier reputation and brand recognition. The relative importance of
these factors varies by market. For example, Dr Solomon's believes that
customers in the United States have placed greater emphasis on price, product
features and ease of use (where the Toolkit generally rates less highly than
competitive products) than on product performance (where the Toolkit generally
rates highly). The Toolkit frequently achieves scores of 100 per cent. against
the virus collections of software testers but competing products have recently
been improving their performance in this respect and have been achieving scores
close to the scores of Dr Solomon's. Should competitive pressures in the
industry increase, Dr Solomon's may have to increase its spending on sales,
marketing and research and development as a percentage of net revenues,
resulting in lower profit margins. In addition, aggressive pricing strategies of
competitors, some of whom have significantly greater financial resources than Dr
Solomon's may cause Dr Solomon's to reduce software prices and/or increase sales
and marketing expenses. Also, there can be no assurance that Dr Solomon's
current and potential competitors will not develop anti-virus products that may
be more effective than Dr Solomon's current or future products.
 
     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, Network Associates has recently reorganized
its direct sales force into three tiers. The first tier focuses on the sale of
the
                                       132
<PAGE>   133
 
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 Network
Associates' individual product suites to customers with less than 1,000 nodes.
Network Associates 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, Network Associates 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, Network Associates 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 Network Associates', suite of products. There can be no assurance
that Network Associates will be successful in building the necessary sales
organization or in attracting, retaining or training these individuals.
Historically, Network Associates has sold its products at the departmental
level. To succeed in the enterprise and national accounts market will require,
among other things, establishing relationships and contacts with senior
technology officers at these accounts. There can be no assurance that Network
Associates or its sales force will be successful in these efforts.
 
     Network Associates' sales organization structure may result in multiple
customer contacts by different Network Associates sales representatives
(particularly in circumstances where the customer has multiple facilities and
offices), a lack of co-ordination between Network Associates' 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 Network Associates'
business, financial condition and results of operations. In addition, while the
development of a direct sales channel reduces Network Associates' dependence on
resellers and distributors, it may lead to conflicts for the same customers and
further customer confusion, pressure by current and prospective customers and
price reductions on products and, consequently, in reductions in Network
Associates' gross margin and operating profit.
 
     PROPRIETARY TECHNOLOGY AND RIGHTS; LITIGATION -- NETWORK
ASSOCIATES. Network Associates' success is heavily dependent upon proprietary
software technology. Network Associates 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 Network Associates'
products.
 
     In December 1997, Network Associates changed its legal name to "Networks
Associates, Inc." and has since begun conducting business as "Network
Associates." Three companies have made unresolved claims or demands with respect
to Network Associates' use of the name "Network Associates": (i) Network
Associates, Inc. of Oregon ("NAI-Oregon"); (ii) Network Associates, Inc. of
Kansas ("NAI-Kansas") and (iii) Ronald L. Myers ("Myers"), a California resident
doing business as The Network Associates. Each of these claimants has asserted
that it has exclusive rights to use the "Network Associates" name and that
Network Associates' use of the name constitutes a violation of those rights.
 
     On 26 March 1998, Network Associates commenced a declaratory judgment
action in the United States District Court for the Northern District of
California against 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.
                                       133
<PAGE>   134
 
     On 24 April 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 20 July 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 6 October 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 Courts order expressly stated that the
court is not enjoining the sale or distribution of McAfee's current product. On
19 December 1997, the Court denied Symantec's motion to enjoin sale or
distribution of Network Associates current PC Medic product. On 1 April 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 10
April 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 5 June 1998. Trial is currently set for
September 1998.
 
     On 13 May 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 22 April 1997.
Trend's complaint seeks injunctive relief and unspecified money damages. On 6
June 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 19 September 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 19 December 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 6 May 1997, RSA Data Security, Inc. ("RSA") filed a lawsuit against PGP,
a wholly owned subsidiary of Network Associates since 9 December 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 RSAs 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 22 May
1997, PGP filed a motion to compel arbitration of the action pursuant to an
arbitration clause in the License Agreement. PGP's motion was granted on 9
October 1997. The Court stayed the state court proceedings and ordered the
action to arbitration.
 
     On 14 October 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 4 November 1997, PGP moved to stay the federal action, or,
in the alternative, compel it to arbitration. On 23 December
 
                                       134
<PAGE>   135
 
1997, RSA filed a motion to amend its complaint to include Network Associates as
defendant. On 2 March 1998, the court granted PGPs motion to stay the federal
patent action.
 
     On 15 April 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. RSA has stipulated to stay this lawsuit on the
same basis as the prior lawsuit against PGP. All of the above matters involving
RSA were settled at a settlement conference on 29 May 1998.
 
     On 15 September 1997, Network Associates was named as a defendant in a
patent infringement action filed by Hilgraeve Corporation ("Hilgraeve") in the
United States District Court, Eastern District of Michigan. Hilgraeve alleges
that Network Associates VirusScan product infringes a Hilgraeve patent which was
issued on 7 June 1994. Hilgraeve's action seeks injunctive relief and
unspecified money damages. The case is in discovery. Discovery is presently
scheduled to be completed by 15 December 1998. There is a status conference
scheduled for 22 September 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 (including those
related to the use of the name Network Associates), there can be no assurance
that such pending litigation will not have a material adverse effect on Network
Associates' business, financial condition or operating results. The litigation
process is subject to inherent uncertainties and no assurance can be given that
Network Associates 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
Network Associates 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 Network Associates.
 
     Network Associates does not typically obtain signed license agreements from
its corporate, government and institutional customers who license products
directly from it. Network Associates 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
Network Associates to protect its proprietary software technology will be
adequate to deter misappropriation of this technology. For example, Network
Associates is aware that a substantial number of users of its anti-virus
products have not paid any registration or license fees to Network Associates.
Changing legal interpretations of liability for unauthorized use of Network
Associates' software, or lessened sensitivity by corporate, government or
institutional users to avoiding copyright infringement, could have a material
adverse effect on Network Associates' business, financial condition and results
of operations.
 
     Network Associates' principal assets are its intellectual property and
Network Associates competes in an increasingly competitive market. There has
been substantial litigation regarding intellectual property rights of technology
companies. Network Associates 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 Network Associates is or may become party which could
have a material adverse effect on Network Associates' business, financial
condition and results of operation.
 
     In addition, as Network Associates 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
                                       135
<PAGE>   136
 
infringement claims exists and will increase to the extent that Network
Associates 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
Network Associates. Network Associates 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 Network Associates' business, financial
condition and results of operations. Adverse determinations in such litigation
could result in the loss of Network Associates' proprietary rights, subject
Network Associates to significant liabilities, require Network Associates to
seek licenses from third parties or prevent Network Associates from
manufacturing or selling its products, any one of which could have a material
adverse effect on Network Associates' 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.
 
     PROPRIETARY TECHNOLOGY AND RIGHTS -- DR SOLOMON'S. Dr Solomon's regards its
software as proprietary and relies upon a combination of license agreements and
copyrights, trademark and trade secret laws in attempting to protect its
proprietary rights. Dr Solomon's products are not generally copy protected. Dr
Solomon's presently has no patents or patent applications pending and has not
registered any of its copyrights. Dr Solomon's has not registered all of its
trademarks, although it has registered its "Dr Solomon's", "Ring Fence" and
"Anti-Stealth Methodology" trademarks in the United Kingdom and has registered
"Dr Solomon's" in several other European countries, including France, Germany,
Italy, The Netherlands, Spain and Sweden and the United States and has applied
for trademark registration for certain trademarks in several other
jurisdictions, including Chile and Japan. Under U.S. copyright and trademark
law, registration is not a condition of copyright and trademark protection.
Registration is, however, a prerequisite to obtaining certain remedies (e.g.
statutory remedies and attorneys' fees) for infringement and, while an
unregistered copyright or trademark is valid and the owner of such unregistered
copyright or trademark may have a valid cause of action for infringement, such
rights cannot be enforced in the federal courts unless and until registration
has been made. In addition, Dr Solomon's believes that the laws of some foreign
countries, including Mexico and India, either do not protect proprietary rights
as fully as do the laws of the United States or the United Kingdom or offer only
limited, if any, practical protection for those rights. While in most countries,
copyright or trademark registration is not required in order to receive
protection, each country may premise the ability to bring an enforcement action
and certain remedies on compliance with that country's copyright or trademark
laws. Consequently, Dr Solomon's failure to register its copyrights and
trademarks in certain countries may make enforcement of these rights more
difficult and/or reduce the available remedies in any enforcement action.
 
     Dr Solomon's uses a printed "break-the-seal" license for its boxed-product
sales for its corporate license customers. Since its "break-the-seal" licenses
are not signed by the licensees, they may not be enforceable under the laws of
certain jurisdictions. Dr Solomon's generally enters into confidentiality or
license agreements with its employees, consultants and distributors, and
generally controls access to and distribution of its software, documentation and
other proprietary information.
 
     Despite Dr Solomon's efforts to protect its proprietary rights, it may be
possible for unauthorized parties to copy certain aspects of Dr Solomon's
products or to reverse engineer or obtain and use information that Dr Solomon's
regards as proprietary. There can be no assurance that the steps taken by Dr
Solomon's to protect its proprietary rights will be adequate to prevent
misappropriation of its technology or to provide an adequate remedy in the event
of a breach by others. Policing unauthorized use of Dr Solomon's products is
difficult, and although Dr Solomon's is unable to determine the extent to which
piracy of its software products exists, software piracy can be expected to be a
persistent problem. It is likely that a substantial number of users of Dr
Solomon's
 
                                       136
<PAGE>   137
 
products have not paid any registration or license fees to Dr Solomon's. If, as
a result of changing legal interpretations of liability for unauthorized use of
Dr Solomon's software, users were to become less sensitive to avoiding copyright
infringement, it could have a material adverse effect on Dr Solomon's. In
addition, litigation may be necessary in the future to protect and enforce Dr
Solomon's proprietary rights, to determine the validity and scope of the
proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on Dr Solomon's.
 
     While Dr Solomon's relies upon a combination of license agreements and
copyright, trademark and trade secret laws as described above, Dr Solomon's
believes that factors such as the superior performance of its products and the
expertise and experience of its personnel are more essential to establishing and
maintaining a technology leadership position.
 
     From time to time, Dr Solomon's receives notices from third parties
claiming infringement by Dr Solomon's products of third party proprietary
rights. Although there are currently no outstanding infringement or invalidity
claims, there can be no assurance that infringement or invalidity claims (or
claims for indemnification resulting from infringement claims) will not be
asserted or prosecuted against Dr Solomon's in the future or that any such
assertions or prosecutions will not have a material adverse effect on Dr
Solomon's. For example, U.S. Patent No. 5,319,776 asserts a patent over "in
transit" virus detection. Dr Solomon's believes that its products do not
infringe this patent. The patent holder has sent a circular to Dr Solomon's
inviting Dr Solomon's to license their technology and has recently taken action
against other anti virus companies on the basis of this patent. There has been
no assertion that Dr Solomon's currently infringes and Dr Solomon's does not
currently intend to license the technology. There can be no assurance, however,
that a claim may not be made in the future. Dr Solomon's expects that software
companies will increasingly be subject to infringement claims as the number of
products and competitors in the anti-virus industry segment grows and the
functionality of products in different industry segments overlaps. For example,
it has been reported recently that Trend Micro has taken legal action against
one of Dr Solomon's competitors claiming infringement of U.S. patent covering
electronic mail interception technology. Any such claim or other claim made
against Dr Solomon's, with or without merit, could result in costly litigation,
cause product shipment delays or require Dr Solomon's to enter into royalty or
licensing agreements. Such royalty or licensing agreements, if required, may not
be available on terms acceptable to Dr Solomon's or at all.
 
     Dr Solomon's licenses certain technology from third parties, including
software that is integrated with internally developed software and used in Dr
Solomon's products to perform key functions. There can be no assurance that
these third party technology licenses will continue to be available to Dr
Solomon's on commercially reasonably terms. The loss of or inability to maintain
any of these technology licenses could result in delays or reductions in product
shipments until equivalent technology is identified, licensed and integrated.
Any such delays or reductions in product shipments could have a material adverse
effect on Dr Solomon's.
 
     RISKS ASSOCIATED WITH INFORMATION SECURITY INDUSTRY. The software security
industry is in an early stage of development. Declines in demand for Dr
Solomon's and Network Associates' security products, whether as a result of
competition, technological change, the public's perception of the need for
security products, developments in the hardware and software environments in
which these products operate, general economic conditions or other factors,
could have a material adverse effect on Dr Solomon's or Network Associates'
financial condition or results of operations.
 
     A well-publicized actual or perceived breach of network or computer
security could trigger a heightened awareness of computer abuse, resulting in an
increased demand for security products such as those offered by Dr Solomon's and
Network Associates. Similarly, an actual or perceived breach of network or
computer security at one of Dr Solomon's or Network Associates' customers,
regardless of whether such breach is attributable to Dr Solomon's or Network
Associates' products, could adversely affect the market's perception of them and
their financial condition or results of
 
                                       137
<PAGE>   138
 
operations. In addition, although the effectiveness of Dr Solomon's or Network
Associates' products is not dependent upon the secrecy of its proprietary
technology or licensed technology, the public disclosure of its proprietary
technology could result in a perception of breached security and reduced
effectiveness of Dr Solomon's or Network Associates' products, which could have
an adverse effect on Dr Solomon's or Network Associates' 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 Network Associates
and Dr Solomon's believe that their products and systems are Year 2000
compliant, Network Associates and Dr Solomon's utilize 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 Network Associates or Dr Solomon's to incur
unanticipated expenses to remedy any problems, which could have a material
adverse effect on Network Associates' business, operating results and financial
condition. The business, operating results and financial condition of Network
Associates' and Dr Solomon'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 Network Associates and Dr Solomon's, which
could have a material adverse effect on Network Associates' or Dr Solomon's
businesses, operating results and financial condition.

        (iii) the terms of an option granted to Dr A.M. Solomon on 6 November
              1996 under the terms of the Group Scheme as amended under the
              terms of a side letter dated 12 November 1996 be varied so as to
              preserve certain terms of the option notwithstanding the
              assignment of the Consultancy Agreement.
 
There are no service contracts between any member of the Dr Solomon's Group and
any director of such company which has more than 12 months to run and no such
agreement has been amended in the six months preceding the Offer period.

                   FURTHER INFORMATION ON NETWORK ASSOCIATES
 
1. SHARE CAPITAL
 
     (a) The authorised share capital of Network Associates as at 23 June 1998
was as follows: 300,000,000 shares of Common Stock, $0.01 par value per share,
and 5,000,000 shares of Preferred Stock, $0.01 par value per share, of which
130,333,155 shares of Common Stock and one share of Series A Preferred Stock
(the only authorised share of Series A Preferred Stock, which was issued in
connection with Network Associates' acquisition of FSA Corporation in September
1996) were in issue.
 
     The share of Series A Preferred Stock has no preferential rights other than
the right to cast a number of votes equal to the number of shares of Network
Associates Common Stock issuable in exchange for certain exchangeable non-voting
shares of FSA Corporation. As at 30 May 1998 such exchangeable shares of FSA
Corporation were exchangeable for 487,593 shares of Network Associates Common
Stock.
 
     The Network Associates' Board has the authority to issue shares of
Preferred Stock in one or more series and to fix the rights, preferences,
privileges and restrictions granted to or imposed upon any unissued and
undesignated shares of Preferred Stock and to fix the number of shares
constituting any series and the designations of such series, without any further
vote or action by the stockholders. Although it presently has no intention to do
so, the Network Associates Board, without stockholder approval, can issue
Preferred Stock with voting and conversion rights which could adversely affect
the voting power or other rights of the holders of Network Associates Common
Stock. The issuance of Preferred Stock may have the effect of delaying,
deferring or preventing a change in control of Network Associates.
 
     Since Network Associates' initial public offering on 6 October 1992, the
Network Associates Common Stock has traded on NASDAQ. Since the combination with
Network General Corporation on 1 December 1997, Network Associates Common Stock
has traded under the symbol NETA. Prior thereto, Network Associates Common Stock
traded under the symbol MCAF.
 
     (b) Upon the Scheme becoming effective, the authorised and issued share
capital of Network Associates will be approximately as follows (based on shares
outstanding as at 31 May 1998 and without giving effect to the exercise of any
option, conversion, any other subscription rights or share issues):

    COMPARISON OF RIGHTS OF DR SOLOMON'S SHAREHOLDERS AND NETWORK ASSOCIATES
                                  STOCKHOLDERS
 
     The following is a summary of the material differences between the rights
of shareholders of Dr Solomon's and the rights of stockholders of Network
Associates arising from the differences between the corporate laws of England
and the Delaware General Corporation Laws ("DGCL"), respectively, and the
requirements of the governing instruments of the two companies. The following
summary does not purport to be a complete description of the rights of
shareholders of Dr Solomon's and rights of the stockholders of Network
Associates, and is qualified in its entirety by reference to, the corporate laws
of England, the DGCL, the memorandum and articles of association of Dr
Solomon's, the Network Associates Certificate of Incorporation and the Network
Associates Bylaws.
 
     In addition to the laws of England and the memorandum and articles of
association of Dr Solomon's, the rights of holders of Dr Solomon's ADSs, which
each represent the right to receive three Dr Solomon's Ordinary Shares, are also
governed by the Deposit Agreement, pursuant to which the Dr Solomon's ADSs have
been issued. Copies of the Deposit Agreement are available for inspection at the
Corporate Trust Office of the Depositary, currently located at 101 Barclay
Street, New York, New York 10286, and at the principal office of the agent of
the Depositary (the "Custodian"), currently located in the London office of The
Bank of New York located at 46 Berkeley Street, London, W1Z 6AD. The
Depositary's principal executive office is located at 101 Barclay Street, New
York, New York 10286.
 
     Dr Solomon's is subject to the Companies Act regulating notices of
shareholder meetings and solicitation of proxies. Notice of a shareholder
meeting is normally accompanied by a shareholder circular (or, in the case of an
annual general meeting, by an annual report and accounts) containing an
explanation of the purpose of the meeting and the board's recommendations with
respect to actions to be taken. All such communications are sent by Dr Solomon's
to the Depositary for distribution to holders of Dr Solomon's ADSs at the same
time as they are sent to holders of Dr Solomon's Ordinary Shares. As a foreign
private issuer with securities listed on NASDAQ and registered under Section 12
of the Exchange Act, Dr Solomon's is required under the Exchange Act to publicly
file with the Commission and NASDAQ annual reports and other information.
 
VOTING RIGHTS
 
     Under English law, the voting rights of shareholders are governed by a
company's articles of association. Cumulative voting is essentially unknown
under English law. The Dr Solomon's Articles of Association specify that two
shareholders present in person or by proxy and entitled to vote constitute a
quorum. Any holder of Dr Solomon's Ordinary Shares on the register may vote in
person or, assuming the proxy is received by Dr Solomon's at least 48 hours
prior to the time set for the meeting, by proxy. There is no record date for
shareholder meetings under English law.
 
     Subject to disenfranchisement in the event of non-compliance with a
statutory notice requiring disclosure as to beneficial ownership, each
registered holder of Dr Solomon's Ordinary Shares present in person (or, if a
corporation, present by a duly authorized representative) or by proxy, is
entitled to cast one vote for each Ordinary Share held.
 
     Under the DGCL, each stockholder is entitled to one vote per share unless
the certificate of incorporation provides otherwise. In addition, the
certificate of incorporation may provide for cumulative voting in the election
of directors of the corporation. Under the Network Associates Certificate of
Incorporation and the Network Associates Bylaws, holders of Network Associates
Common Stock are entitled to one vote per share on all matters and the holder of
the share of Series A Preferred Stock is entitled to that number of votes equal
to the number of shares of Network Associates Common Stock issuable upon
exchange of then outstanding exchangeable
 
                                       149
<PAGE>   150
 
shares of FSA Corporation, an Alberta corporation, and cumulative voting is not
permitted. A quorum consists of a majority of the shares entitled to vote,
unless otherwise required by law.
 
ACTION BY WRITTEN CONSENT
 
     Dr Solomon's Articles of Association contain a provision enabling the
passing of a resolution by unanimous written consent of all shareholders
entitled to attend and vote.
 
     Under the DGCL, unless otherwise provided in the certificate of
incorporation, an action required or permitted to be taken at any meeting of
stockholders may instead be taken without a meeting, without prior notice or a
vote if a written consent to the action is signed by holders of outstanding
shares of stock having at least the number of votes that would be required to
authorize such action at a meeting of stockholders at which all shares entitled
to vote thereon were present and voting. Under the Network Associates
Certificate of Incorporation, holders of Network Associates Common Stock may not
take any action required to be taken at a meeting of stockholders or any other
action which may be taken at a meeting of stockholders, without a meeting and
the power of stockholders to consent in writing to the taking of any action
without a meeting is specifically denied.
 
SOURCES AND PAYMENT OF DIVIDENDS
 
     Under English law, a company may pay dividends on its ordinary shares,
subject to the prior rights of holders of its preferred shares, only out of its
distributable profits (accumulated, realized profits (not previously utilized by
distribution or capitalization) less accumulated, realized losses) and not out
of share capital, which includes share premiums (paid-in surplus). Amounts
credited to the share premium account (representing the excess of the
consideration for the issue of shares over the aggregate par value of such
shares) may not be paid out as cash dividends but may be used, among other
things, to pay up unissued shares which may then be distributed to shareholders
in proportion to their holdings and for other limited purposes. In addition, a
public company such as Dr Solomon's may make a distribution at any time only if,
at that time and immediately after such distribution the amount of its net
assets is not less than the aggregate of its called-up (i.e., issue and paid-up)
share capital and undistributable reserves. Under English law, a dividend must
be declared by reference to relevant accounts showing the availability of
distributable reserves for such dividends. As a public company, the relevant
accounts for Dr Solomon's are its last audited accounts or, where such accounts
do not show sufficient distributable reserves, interim accounts (which need not
be audited) prepared and filed with the Registrar.
 
     Under the Dr Solomon's Articles of Association, the directors may pay to
holders of Dr Solomon's Ordinary Shares such interim dividends (i.e. dividends
resolved to be paid by directors without the approval of shareholders in a
general meeting), as appear to the directors to be justified by the profits of
Dr Solomon's. Any dividend unclaimed after the period of 12 years from the date
of its declaration may be forfeited and shall revert to Dr Solomon's. Each
dividend on ordinary shares will be paid to the holders thereof on the register
of members on the record date for such dividend who have not waived their
entitlement thereto.
 
     The DGCL permits the payment of dividends on common stock, subject to any
restrictions contained in the certificate of incorporation, either (i) out of
its "surplus" (as defined below) or (ii) if there is no "surplus", out of its
net profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year; except that no dividends may be paid out of such net
profits if the net assets of the corporation are less than the aggregate amount
of capital represented by the issued and outstanding stock having a preference
upon the distribution of assets. "Surplus" is defined in the DGCL as the amount
by which net assets (total assets less total liabilities) exceeds the capital of
the corporation. In accordance with the DGCL, "capital" is determined by the
board of directors and will not be less than the aggregate par value of the
outstanding capital stock of the corporation having par value. In addition, the
DGCL generally provides that a corporation may
 
                                       150
<PAGE>   151
 
redeem or repurchase its own shares only if such redemption or repurchase would
not "impair the capital" of the corporation. The ability of a Delaware
corporation to pay dividends on, or redeem or to make repurchases or redemptions
of, its shares is dependent on the financial status of the corporation standing
alone and not on a consolidated basis. The Network Associates Certificate of
Incorporation and the Network Associates Bylaws do not restrict the payment of
dividends on Network Associates Common Stock.
 
RIGHTS OF PURCHASE AND REDEMPTION
 
     Under English law, a company may issue redeemable shares if authorized by
its articles of association and subject to the conditions stated therein. The Dr
Solomon's Articles of Association do permit the issue of redeemable shares. A
company may purchase its own shares, including any redeemable shares, if
authorized by its articles of association and provided that such purchase has
been previously approved by an ordinary resolution of its shareholders in the
case of an on-market purchase or a special resolution in other cases. Shares may
be purchased only if fully paid and, in the case of public companies, only,
subject as provided below, out of distributable profits or the proceeds of a new
issue of shares issued for the purpose of the purchase. When shares are
purchased wholly out of profits, the amount by which the par value of the
company's issued share capital is diminished on cancellation of the shares so
purchased must be transferred to the capital redemption reserve, which is
generally treated as paid-up share capital. In addition, any amount payable on
purchase of any shares in excess of the par value thereof may be paid out of the
proceeds of a fresh issue of shares up to an amount equal to whichever is the
lesser of the aggregate of the premiums received by the company on the issue of
those shares or the amount of the company's share premium account as at the time
of the purchase including any sum transferred to that account in respect of
premiums on the new issue.
 
     Under the DGCL, a corporation may purchase or redeem shares of any class of
its capital stock, but subject generally to the availability of sufficient
lawful funds therefor and provided that at all times that, at the time of any
such redemption, the corporation shall have outstanding shares of one or more
classes or series of capital stock, which have full voting rights that are not
subject to redemption. The Network Associates Certificate of Incorporation and
the Network Associates Bylaws do not restrict this right.
 
MEETINGS OF SHAREHOLDERS
 
     Under English law, an annual general meeting (an "AGM") of a public company
must be held each year and at least once every fifteen months, and an
extraordinary general meeting (an "EGM") of shareholders may be called by the
board of directors or (notwithstanding any provision to the contrary in a
company's articles of association) by a request from shareholders holding not
less than one-tenth of the paid-up capital of the company carrying voting rights
at general meetings. An EGM at which an ordinary resolution is proposed requires
14 clear days' notice (other than an ordinary resolution to remove a director
which requires 21 clear days' notice). Such ordinary resolution requires a
majority of the votes cast by those present (in person or by proxy). An EGM at
which a special resolution is proposed requires 21 clear days' notice and such
resolution requires a three-quarters majority of the votes cast by those present
(in person or by proxy). An AGM requires 21 clear days' notice regardless of the
types of resolution to be proposed. The term "clear days' notice" means calendar
days and excludes the date of mailing, the deemed date of receipt of such notice
(which is provided for in the articles of association when first-class mail is
employed), and the date of the meeting itself. "Extraordinary resolutions" are
relatively unusual and are confined to certain matters out of the ordinary
course of business such as a proposal to wind up the affairs of the company.
Proposals that are the normal subject of "special resolutions" generally involve
proposals to change the name of the company, to alter its capital structure, to
change or amend the rights of shareholders, to permit the company to issue new
shares for cash without applying the shareholders' preemptive rights and to
amend the company's objects (purpose)
 
                                       151
<PAGE>   152
 
clause in its memorandum of association and articles of association and to carry
out certain other matters where either the company's articles of association or
the Companies Act prescribe that a "special resolution" is required. All other
proposals relating to the ordinary course of the company's business such as the
election of directors would be the subject of an "ordinary resolution".
 
     Under the DGCL, Network Associates is required to hold annual meetings of
its stockholders. Special meetings of stockholders may be called by the board of
directors or by such person or persons as may be authorized by the certificate
of incorporation or bylaws. The Network Associates Certificate of Incorporation
provides that a special meeting of stockholders may be called by a resolution of
the Network Associates Board or by the holders of shares entitled to cast not
less than 10 per cent. of the votes at the meeting. Under the DGCL, holders of
the Network Associates Common Stock must receive notice of any annual or special
meeting not less than ten nor more than 60 days prior to such meeting. The
record date for the meetings of the stockholders shall not be less than ten days
nor more than 60 days before the date of such meeting. The Network Associates
Certificate of Incorporation does not provide otherwise.
 
RIGHTS OF APPRAISAL
 
     While English law does not generally provide for appraisal rights, if a
shareholder applies to a Court as described under "Shareholders' Votes on
Certain Reorganizations" below, the Court may specify such terms for the
acquisition as it considers appropriate. English law provides shareholders with
rights to dissent in respect of a reorganization of a company under Section 110
of the Insolvency Act of 1986 of England and Wales (the "Insolvency Act"). In
addition, dissenters' rights exist where an offeror who, pursuant to a takeover
offer for a company, has acquired or contracted to acquire not less than
nine-tenths in value of the shares to which the offer relates, seeks to acquire
compulsorily outstanding minority shareholdings.
 
     Under the DGCL, stockholders who follow prescribed statutory procedures are
entitled, in the event of certain mergers or consolidations, to surrender their
shares to the corporation in exchange for the judicially determined "fair value"
of such shares. Such stockholders are entitled to such appraisal rights unless
the shares of stock (or depositary receipts in respect thereof) held by the
stockholder are either (i) listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or (ii) held of
record by more than 2,000 holders. No appraisal rights are available for any
shares of stock of the constituent corporation surviving a merger if the merger
did not require for its approval the vote of the stockholders of the surviving
corporation as provided in the DGCL. Regardless of the foregoing, appraisal
rights are available for the shares of any class or series of stock of a
constituent corporation if the holders thereof are required by the terms of an
agreement of merger or consolidation to accept for such stock anything except
(i) shares of stock of the corporation surviving or resulting from such merger
or consolidation, or depositary receipts in respect thereof; (ii) shares of
stock of any other corporation or depositary receipts in respect thereof, which
shares of stock or depositary receipts at the effective date of the merger or
consolidation will be either listed on a national securities exchange or
designated as a market system security on an interdealer quotation system by the
National Association of Securities Dealers, Inc. or held of record by more than
2,000 holders; (iii) cash in lieu of fractional shares or fractional depositary
receipts described in the foregoing clauses (i) and (ii); or (iv) any
combination of the shares of stock, depositary receipts and cash in lieu of
fractional shares, or fractional depositary receipts described in the foregoing
clauses (i), (ii) and (iii).
 
PREEMPTIVE RIGHTS
 
     Under English law, the issue for cash of equity securities (securities that
with respect to dividends or capital carry a right to participate beyond a
specified amount) or rights to subscribe for or convert into equity securities
must be offered in the first instance to the existing equity
 
                                       152
<PAGE>   153
 
shareholders in proportion to the respective nominal values of their holdings,
unless a special resolution has been passed in a general meeting of shareholders
to the contrary.
 
     Unless the certificate of incorporation expressly provides otherwise,
stockholders of a Delaware corporation do not have preemptive rights. The
Network Associates Certificate of Incorporation does not provide for preemptive
rights.
 
AMENDMENT OF GOVERNING INSTRUMENTS
 
     Under English law, the shareholders have the authority to alter, delete,
substitute or add to the objects clause in a company's memorandum and all
provisions of its articles of association by a vote of not less than
three-quarters of the shareholders entitled to vote and who do vote, either in
person or by proxy, at a general meeting subject, in the case of certain
alterations to the memorandum of association, to the right of dissenting
shareholders to apply to the courts to cancel the alterations. Under English
law, the board of directors is not authorized to change the memorandum or the
articles of association. Amendments affecting the rights of the holders of any
class of shares may, depending on the rights attached to such class and the
nature of the amendments, also require approval of the classes affected in
separate class meetings.
 
     Under the DGCL, all amendments to a corporation's certificate of
incorporation require the approval of stockholders holding a majority of the
voting power of the corporation unless a different proportion is specified in
the certificate of incorporation. The Network Associates Certificate of
Incorporation does not specify a different proportion, except that the following
provisions of the Network Associates Certificate of Incorporation may be amended
only by the favourable vote of the holders of shares representing at least
two-thirds of the voting power of all the then outstanding shares of capital
stock of Network Associates entitled to vote generally in the election of
directors, voting as a single class, (i) the provision restricting stockholder
action by written consent, (ii) the provision setting the number and
classification of the Network Associates board the right to fill any vacancies
and providing for the removal of Network Associates directors, (iii) the
provision expressly authorizing the Network Associates Board to amend the
Network Associates Bylaws, (iv) the provision regarding the limitation on
liability and indemnification of Network Associates directors, and (v) the
provision requiring the two-thirds vote of the Network Associates stockholders
to amend or repeal certain provisions of the Network Associates Certificate of
Incorporation.
 
     Under the DGCL, the bylaws of a corporation generally may be amended or
repealed by the affirmative vote of the holders of a majority of the issued and
outstanding stock of the corporation entitled to vote thereon as a class. The
Network Associates Certificate of Incorporation provides that the Network
Associates Bylaws maybe amended repealed or new bylaws adopted by a resolution
of the Network Associates Board or the affirmative vote of the holders of at
least two-thirds of the voting power of all the then outstanding shares of
capital stock of Network Associates entitled to vote generally in the election
of directors, voting together as a single class.
 
SHAREHOLDERS' VOTES ON CERTAIN TRANSACTIONS
 
     Under the Companies Act, fundamental corporate changes, such as the passing
of a resolution for winding up, non pro rata issues of shares for cash,
reductions of capital (subject to sanction by the court) and certain repurchases
of shares may be authorized by a special resolution passed at a general meeting
of shareholders. Subject to the provisions of the Companies Act, if at such
time, the capital of Dr Solomon's is divided into different classes of shares
and the amendment or other resolution would cause any of the special rights
attached to any class of shares to be varied or abrogated, the amendment must
also be sanctioned by the holders of at least three-quarters in nominal value of
the class concerned who vote.
 
     The Companies Act provides for schemes of arrangement, which are
arrangements or compromises between a company and any class of its shareholders
(or any class of its creditors) and are used for certain types of
reconstructions, amalgamations, capital reorganizations or takeovers.
                                       153
<PAGE>   154
 
They require the approval at an extraordinary general meeting of the company
convened by order of the court of a majority in number of the shareholders
representing three-fourths in value of the capital or class of creditors or
shareholders or class of shareholders present and voting, either in person or by
proxy, and the sanction of the High Court. Once so approved and sanctioned, all
creditors or shareholders (of the relevant class) are bound by the terms of the
scheme; a dissenting shareholder would have no rights comparable to dissenter's
rights described below. A scheme of reconstruction under Section 110 of the
Insolvency Act may be made when a company is being wound up voluntarily under
which, with the sanction of a special resolution of shareholders in a general
meeting the whole or part of the company's business or property is transferred
to a second company in consideration for the issue or transfer to them of shares
in the second company. Any dissenting shareholder can require the liquidator to
abstain from carrying the resolution into effect or to purchase his interest at
a price agreed or determined by arbitration. The Companies Act also provides
that where a takeover offer (as defined therein) is made for the shares of a
company incorporated in the United Kingdom and, within four months of the date
of the offer the offeror has, by virtue of acceptances of the offer, acquired or
contracted to acquire not less than nine-tenths in value of the shares of any
class to which the offer relates, the offeror may, within two months of reaching
the nine-tenths level, by notice require shareholders who do not accept the
offer to transfer their shares on the terms of the offer. A dissenting
shareholder may apply to the Court within six weeks of the date on which such
notice was given objecting to the transfer or its proposed terms. The Court is
unlikely (absent fraud or oppression) to exercise its discretion to order that
the acquisition not take effect, but it may specify such terms of the transfer
as it finds appropriate. A minority shareholder is also entitled in these
circumstances to require the offeror to acquire his shares on the terms of the
offer. In the United Kingdom, takeovers of public companies, such as Dr
Solomon's, are regulated by the City Code. The City Code is administered by the
Panel, a body comprising representatives of certain City of London financial and
professional institutions which oversees the conduct of such takeovers. One of
the provisions of the City Code is to the effect that: (i) when any person
acquires, whether by a series of transactions over a period of time or not,
shares which (taken together with shares held or acquired by persons acting in
concert with him) carry 30 per cent. or more of the voting rights of a public
company; or (ii) when any person, together with a person acting in concert with
him, holds not less than 30 per cent. but not more than 50 per cent. of the
voting rights and such person acting in concert with him, acquires in any period
of 12 months additional shares carrying more than 1 per cent. of the voting
rights such person must generally make an offer for all of the equity shares of
the company (whether voting or non-voting) for cash, or accompanied by a cash
alternative, at not less than the highest price paid for the relevant shares
during the 12 months preceding the date of the offer.
 
     Section 203 of the DGCL prohibits a corporation that has securities traded
on a national securities exchange, designated on NASDAQ or held of record by
more than 2,000 stockholders from engaging in certain business combinations,
including a merger, sale of substantial assets, loan or substantial issuance of
stock, with an interested stockholder, or an interested stockholder's affiliates
or associates, for a three-year period beginning on the date the interested
stockholder acquires 15 per cent. or more of the outstanding voting stock of the
corporation. The restrictions on business combinations do not apply if (i) the
board of directors gives prior approval to the transaction in which the 15 per
cent. ownership level is exceeded, (ii) the interested stockholder acquires, in
the transaction pursuant to which the interested stockholder becomes the owner
of 15 per cent. or more of the outstanding stock, 85 per cent. of the
corporation's stock (excluding those shares owned by persons who are directors
and also officers, as well as employee stock plans in which employees do not
have a confidential right to determine whether shares held subject to the plan
will be tendered in a tender or exchange offer) or (iii) the business
combination is approved by the board of directors and authorized at a meeting of
stockholders by the holders of at least two-thirds of the outstanding voting
stock, excluding shares owned by the interested stockholder. Although a Delaware
corporation may elect, pursuant to its certificate of incorporation or by-laws,
 
                                       154
<PAGE>   155
 
not to be governed by this provision, the Network Associates Certificate of
Incorporation and the Network Associates Bylaws contain no such election.
 
RIGHTS OF INSPECTION
 
     Except when closed in accordance with the provisions of the Companies Act,
the register and index of names of shareholders of a company, together with
certain other registers required to be maintained by such a company, may be
inspected during business hours by its shareholders, including, in the case of
Dr Solomon's, holders of Dr Solomon's ADSs, without charge and by other persons
upon payment of a fee, and copies may be obtained on payment of a fee. The
shareholders of an English public company may, without charge, also inspect the
minutes of meetings of the shareholders during business hours and obtain copies
upon payment of a fee. The published directors' report and audited annual
accounts of a public company are required to be laid before the shareholders in
a general meeting and a shareholder is entitled to a copy of such reports and
accounts. Copies are filed with the Registrar from whom copies are publicly
available upon payment of the appropriate fee. The shareholders of Dr Solomon's,
including holders of Dr Solomon's ADSs, have no rights to inspect its accounting
records or minutes of meetings of its directors. Certain registers required to
be kept by the company are open to public inspection and service contracts of
directors of the company (which have more than 12 months unexpired or require
more than 12 months' notice to terminate) must be available for inspection
during business hours.
 
     The DGCL allows any stockholder, upon written demand under oath stating the
purpose thereof, to have the right, during the usual hours of business, to
inspect, for any proper purpose, the corporation's stock ledger, a list of its
stockholders, and its other books and records, and to make copies or extracts
therefrom. A proper purpose means a purpose reasonably related to such person's
interest as a stockholder.
 
CLASSIFICATION OF THE BOARD OF DIRECTORS
 
     English law permits a company to provide for the classification of the
board of directors with respect to the time for which directors severally hold
office. The Dr Solomon's Articles of Association provide that unless otherwise
resolved by the shareholders in General Meeting the number of directors shall
not be subject to any maximum but shall be not less than two. They further
provide that at each AGM of Dr Solomon's one-third (or if their number is not
three or a multiple of three, the number nearest to one-third) of the directors
who are subject to retirement by rotation shall retire from office by rotation.
The directors to retire by rotation in every year include first, a director who
wishes to retire and not offer himself for reappointment, and second, those
directors who have been longest in office since their last appointment or
reappointment, but, as between persons who became directors on the same day,
those to retire (unless they otherwise agree among themselves) are determined by
lot. A retiring director is eligible for re-election. A director is required to
retire at the conclusion of the AGM following his attaining the age of 70 unless
shareholders in General Meeting approve his re-election.
 
     Under the DGCL, the certificate of incorporation of a Delaware corporation
may provide for the classification of the board of directors in order to stagger
the terms of directors. The term "classified board" generally means the
specification of selected board seats for a term of more than one year (but not
more than three years), with different classes of board seats coming up for
election each year. The Network Associates Certificate of Incorporation provides
for a classified board of directors consisting of three classes of directors,
with each class elected for a term of three years.
 
REMOVAL OF DIRECTORS
 
     Under the Companies Act, shareholders have the right to remove a director
without cause by ordinary resolution of which special notice (28 clear days) has
been given to the company, irrespective of the provisions of the articles of
association of the company.
 
                                       155
<PAGE>   156
 
     Under the DGCL, any director or the entire board of directors may be
removed, with or without cause, by the holders of a majority of the shares then
entitled to vote at the election of directors, unless the certificate of
incorporation provides otherwise. If the shareholders are entitled to cumulative
voting and less than the entire board is to be removed, no individual director
may be removed without cause if the number of votes cast against the resolution
of his removal would be sufficient if cumulatively voted to elect such director
to the board. The Network Associates Certificate of Incorporation provides that
directors may be removed only for due cause by a vote of the record holders of a
majority of the holders of stock entitled to vote thereon. Under the DGCL, the
stockholders of a corporation that has a classified board of directors, such as
Network Associates, may only remove directors for cause.
 
VACANCIES ON THE BOARD OF DIRECTORS
 
     Under English law, shareholders of an English public company may, by
ordinary resolution at a meeting at which any director retires by rotation,
appoint a person who is willing to be a director either to fill a vacancy or as
an additional director. The board of directors also has the power to appoint a
director to fill a vacancy or as an additional director, subject to such
conditions as may be set out in Dr Solomon's articles of association, provided
that such appointment will only last until the next following annual general
meeting of the company, at which the director concerned may be re-elected.
 
     Under the DGCL, the board of directors of a corporation may fill any
vacancy on the board, including vacancies resulting from an increase in the
number of directors. Under the Network Associates Bylaws, in case of vacancy
among the directors, the remaining directors, even if less than a quorum, by an
affirmative vote of a majority thereof, may fill such vacancy.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     English law does not permit a company to indemnify a director or an officer
of the company or any person employed by the company as an auditor against any
liability that, by virtue of any rule of law, would otherwise attach to him in
respect of negligence, default, breach of duty or breach of trust in relation to
the company, except liability incurred by such director, officer or auditor in
defending any legal proceedings (whether civil or criminal) in which judgment is
given in his favor or in which he is acquitted or in certain instances in which,
although he is liable, a court finds that such director, officer or auditor
acted honestly and reasonably and that, with regard to all the circumstances, he
ought fairly to be excused and relief is granted by the court. Section 310 of
the Companies Act enables companies to purchase and maintain insurance for
directors, officers and auditors against any liability that would otherwise
attach to them in respect of any negligence, default, breach of duty or breach
of trust in relation to the company. Dr Solomon's has purchased and maintains in
force such insurance.
 
     The DGCL provides that a corporation may, and in certain circumstances
must, indemnify its directors, officers, employees and agents for expenses,
judgments or settlements actually and reasonably incurred by them in connection
with suits and other legal actions or proceedings if they acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe their conduct was unlawful. In
any such suit or action brought by or on behalf of the corporation, such
indemnification is limited to expenses reasonably incurred in defense or
settlement of the suit or action. The DGCL also permits a corporation to adopt
procedures for advancing expenses to directors, officers and others without the
need for a case-by-case determination of eligibility, so long as, in the case of
officers and directors, they undertake to repay the amounts advanced if it is
ultimately determined that the officer or director was not entitled to be
indemnified. The Network Associates Certificate of Incorporation and the Network
Associates Bylaws contain provisions for indemnification of directors and
officers and for the advancement of expenses to any director or officer to the
fullest extent of the law. The DGCL permits corporations to
                                       156
<PAGE>   157
 
purchase and maintain insurance for directors and officers against liability for
expenses, judgments or settlements, whether or not the corporation would have
the power to indemnify such persons therefor. The Network Associates Bylaws
permit Network Associates to purchase such insurance.
 
     The DGCL permits a Delaware corporation to include in its certificate of
incorporation a provision eliminating the personal liability of directors for
monetary damages for certain breaches of fiduciary duty in a lawsuit by or on
behalf of the corporation or in an action by stockholders of the corporation.
The Network Associates Certificate of Incorporation eliminates a director's
monetary liability in a lawsuit by or on behalf of the corporation or in an
action by stockholders of the corporation to the full extent permitted by the
DGCL.
 
SHAREHOLDERS' SUITS
 
     In addition to having the right to institute a lawsuit on behalf of the
company in certain limited circumstances under English law, Section 459 of the
Companies Act permits a shareholder whose name is on the register of members of
the company (including U.S. persons) to apply for a court order when the
company's affairs are being or have been conducted in a manner unfairly
prejudicial to the interests of the shareholders generally or some part of the
shareholders, including at least the petitioning shareholder, or where any
actual or proposed act or omission of the company is or would be so prejudicial.
A court, when granting relief in an action complaining of unfair prejudice, has
wide discretion, including authorizing civil proceedings to be brought in the
name of the company by a shareholder on such terms as the court may direct.
Except in these limited respects, English law does not permit class-action
lawsuits by shareholders on behalf of the company or on behalf of other
shareholders.
 
     Under Delaware law, a shareholder may institute a lawsuit against one or
more directors, either on his own behalf, or derivatively on behalf of the
corporation. An individual stockholder may also commence a lawsuit on behalf of
himself and other similarly situated stockholders when the requirements for
maintaining a class action under Delaware law have been met. Section 102(b)(7)
of the DGCL, enables a corporation in its certificate of incorporation to
eliminate or limit the personal liability of a director for monetary damages for
violations of the director's fiduciary duty, except (i) for any breach of a
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for liability pursuant to 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.
 
DISCLOSURE OF INTERESTS
 
     Section 198 of the Companies Act provides that a person (including a
company and other legal entities) who acquires an interest or becomes aware that
he has acquired an interest of 3 per cent. or more of any class of shares
comprised in a public company's "relevant share capital" (which, for these
purposes, means that company's issued share capital carrying rights to vote in
all circumstances at general meetings of the company) is obliged to notify that
company of his interest within two business days following the day on which the
obligation arises. Thereafter, any changes in respect of whole percent figure
increases or decreases, rounded down to the next whole number or which reduce
such interest below 3 per cent., must be notified to the company. The Dr
Solomon's Ordinary Shares are "relevant share capital" for this purpose.
 
     In addition, the Companies Act provides that a public company may, by
notice in writing (a "Section 212 Notice"), require a person whom the company
knows or has reasonable cause to believe to be, or to have been at any time
during the three years immediately preceding the date on which the notice is
issued, interested in shares comprised in the company's "relevant share capital"
to confirm that fact or (as the case may be) to indicate whether or not that is
the case, and when he holds or has, during relevant time held an interest in
such shares, to give such further information as
 
                                       157
<PAGE>   158
 
may be required relating to his interest and any other interest in the shares of
which he is aware. The disclosure must be made within such reasonable period as
may be specified in the relevant notice (which may, depending on the
circumstances, be as short as one or two days).
 
     For the purpose of the above obligations, the interest of a person in
shares means any kind of interest in shares, including interests in any shares
(i) in which his spouse, or his child or stepchild under the age of 18, is
interested, (ii) if a corporate body is interested in them and either (a) that
corporate body is or its directors are accustomed to act in accordance with that
person's directions or instructions or (b) that person is entitled to control or
controls one-third or more of the voting power of that corporate body or (iii)
if another party is interested in shares and the person and that other party are
parties to a "concert party" agreement under Section 204 of the Companies Act
(being an agreement that provides for one or more parties to it to acquire
interests in shares of a particular public company, which imposes obligations or
restrictions on any one or more of the parties as to the use, retention or
disposal of such interests acquired pursuant to such agreement and any interest
in the company's shares is in fact acquired by any of the parties pursuant to
the agreement). Such a concert party need not be in writing. The holding of a Dr
Solomon's ADS would generally constitute an interest in the underlying Dr
Solomon's Ordinary Shares.
 
     When a Section 212 Notice is served by a company on a person who is or was
interested in shares of the company and that person fails to give the company
any information required by the notice within the time specified in the notice,
the company may apply to the court for an order directing that the shares in
question be subject to restrictions prohibiting, inter alia, any transfer of
those shares, the exercise of voting rights in respect of such shares, the issue
of further shares in respect of such shares and, other than in a liquidation,
payments, including dividends, in respect of such shares. Such restrictions may
also void any agreement to transfer such shares. In addition, a person who fails
to fulfil the obligations described above is subject to criminal penalties in
the United Kingdom.
 
     Acquirors of Network Associates Common Stock are subject to disclosure
requirements under Section 13(d)(1) of the Exchange Act and Rule 13d-1
thereunder, which provide that any person who becomes the beneficial owner of
more than 5 per cent. of the issued and outstanding Network Associates Common
Stock shall, within 10 days after such acquisition, file a Schedule 13D or 13G,
as the case may be, with the Commission disclosing certain specified
information, and send a copy of the Schedule 13D or 13G, as the case may be, to
Network Associates and to the securities exchange on which the security is
traded.
 
     After the Acquisition, acquirors of Network Associates Common Stock will be
required to comply with, among other things, the provisions of Section 13(d) of
the Exchange Act and Rule 13d-1 thereunder.

     Per share amounts for Network Associates Common Stock have been restated to
give retroactive effect to the Network Associates 3-for-2 Stock Split.
 
     Because the exchange ratio is fixed, changes in the market price of Network
Associates Common Stock will affect the market value of the Network Associates
Common Stock to be received by holders of Dr Solomon's Shares pursuant to the
Scheme. Dr Solomon's Shareholders should obtain current market quotations for
Network Associates Common Stock and Dr Solomon's ADSs prior to the Extraordinary
General Meeting.
 
     Neither Network Associates nor Dr Solomon's has paid any cash dividends
since October 1992 and November 1996 respectively. Network Associates currently
intends that, for the foreseeable future following the Effective Date, Network
Associates will retain earnings for development of its business and not
distribute earnings to stockholders as dividends. The declaration and payment by
Network Associates following the Effective Date of future dividends, if any, and
the amount thereof will depend upon Network Associates' results of operations,
financial condition, cash requirements, future prospects, limitations imposed by
credit agreements or senior securities and other factors deemed relevant by the
Network Associates Board.
 
5. COMPARATIVE PER SHARE DATA
 
     The following table sets forth certain historical per share data of Network
Associates Common Stock and Dr Solomon's Ordinary Shares and combined per share
data on an unaudited pro forma basis after giving effect to the Acquisition on a
pooling of interests basis of accounting, assuming that 0.27625 of a share of
Network Associates Common Stock is issued in exchange for one Dr Solomon's
Ordinary Share (or 0.82875 per Dr Solomon's ADS). This data should be read in
conjunction with selected historical financial data, the unaudited pro forma
combined financial information, and the separate historical financial statements
of Network Associates and Dr Solomon's and notes thereto (which are included in
Appendices 2, 3 and 6 of this document). The pro forma combined financial data
is not necessarily indicative of the operating results that would have been
achieved had the Acquisition been consummated as of the beginning of the periods
presented and should not be construed as representative of future performance or
results of operations. Per share information set forth in the historical
financial statements of Network Associates for the years

(1) The historical book value per share is computed by dividing stockholders'
    equity by the number of shares of common stock and preferred stock, on an as
    if converted basis outstanding at the end of each period.
 
(2) The pro forma combined net income per share for the years ended 31 December
    1995, 1996 and 1997 include Dr Solomon's net income per share based on the
    aggregation of unaudited quarterly information for the years ended 30
    November 1995, 1996 and 1997, respectively. The pro forma combined net
    income per share for the three months ended 31 March 1998 includes Dr
    Solomon's income per share for the quarter ended 28 February 1998.
 
(3) The Dr Solomon's equivalent pro forma combined per share amounts are
    calculated by multiplying the combined pro forma per share amounts by the
    exchange ratio of 0.27625 of a share of Network Associates Common Stock for
    each Dr Solomon's Ordinary Share.
 
(4) The pro forma combined book value per share is computed by dividing pro

     9B of the Company:
 
"SCHEME OF ARRANGEMENT
 
     "9B
 
          (a) In this Article, references to the "Scheme" are to the scheme of
     arrangement dated 26 June 1998 under section 425 of the Companies Act 1985,
     between the Company and the holders of the Scheme Shares (as defined in the
     Scheme), as it may be modified or amended in
 
                                       184
<PAGE>   185
 
     accordance with its terms and expressions defined in the Scheme shall have
     the same meaning in this Article.
 
          (b) If any ordinary shares in the Company are allotted and issued
     after 26 June 1998 and prior to the Record Date, such ordinary shares shall
     be subject to the terms of the Scheme and the holder or holders thereof
     shall be bound by the Scheme accordingly.
 
          (c) If any ordinary shares in the Company are allotted and issued or
     transferred to any person (a "new member"), other than Networks Associates,
     Inc. ("Network Associates") or any person identified by written notice to
     the Company from Network Associates or its subsidiary or nominee, at any
     time after the Record Date such ordinary shares will be transferred
     immediately to Network Associates (or as Network Associates may direct by
     notice in writing to the Company) free from all liens, charges, or
     encumbrances of any nature whatsoever.
 
          (d) In consideration for the transfer to or as directed by Network
     Associates under Article 9B(c), Network Associates shall issue or transfer
     to the new member, or procure the issue or transfer to the new member of,
     0.27625 shares of Common Stock, par value US$0.01, of Network Associates
     ("Network Associates Stock"), fully paid up and non-assessable and free
     from all liens, charges or encumbrances of any nature whatsoever, for each
     Ordinary Share so transferred, save that no fraction of a Network
     Associates Stock will be issued or transferred pursuant to this Article,
     but in lieu thereof each new member who would otherwise be so entitled to
     such a fraction (after aggregating all fractions of Network Associates
     Stock to be received by such a person) shall instead be paid by Network
     Associates, or Network Associates shall procure the payment of, an amount
     in cash payable in United States dollars (rounded to the nearest whole U.S.
     cent) equal to the product of such fraction of a Network Associates Stock
     multiplied by the last sale price per share of Network Associates Stock as
     reported on NASDAQ on the Business Day immediately following the Effective
     Date. Network Associates Stock issued or transferred to the new member will
     be fully paid and non-assessable and will rank equally in all respects with
     all Network Associates Stock in issue at the time (other than as regards
     any dividend or other distribution payable by reference to a record date
     preceding the date of issue or transfer, or the Record Date, whichever is
     later) and be subject to the Bylaws of Network Associates.
 
          (e) The number of Network Associates Stock to be issued or transferred
     to the new member under Article 9B(c) may be adjusted by the directors in
     such manner as the auditors may determine on any reorganisation of the
     share capital of the Company or of Network Associates effected after the
     Record Date save that no fraction of Network Associates Stock will be
     issued or transferred pursuant thereto, but in lieu thereof each new member
     who would otherwise be so entitled to such a fraction (after aggregating
     all fractions of Network Associates Stock to be received by such a person)
     shall instead be paid by Network Associates, or Network Associates shall
     procure the payment of, an amount in cash payable in U.S. dollars (rounded
     to the nearest whole U.S. cent) as the auditors shall (in their absolute
     discretion) determine ensures as nearly as may be parity of treatment with
     that provided for by Article 9B(d) above.
 
          (f) To give effect to any such transfer required by sub-paragraph(c)
     of this Article 9B, the Company may appoint any person to execute and
     deliver a form of transfer on behalf of the new member in favour of Network
     Associates (or as directed by Network Associates) and to agree for and on
     behalf of the new member to become a stockholder in Network Associates.
 
          (g) If the Scheme shall not have become effective by the date referred
     to in Clause 4(b) of the Scheme, Article 9B shall be of no effect";
 
          (ii) the renumbering of the existing Article 9 of the Articles of
     Association of the Company as Article 9A; and
 
                                       185
<PAGE>   186
 
          (iii) the insertion of the words "or otherwise in such manner and to
     such person(s) as the Company in General Meeting shall resolve" immediately
     following the words ". . . partly in the other," where such words appear in
     the last line of the first sentence of Article 130 of the Articles of
     Association of the Company.

THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
DR SOLOMON'S GROUP PLC
AYLESBURY, ENGLAND

        We have audited the accompanying consolidated balance sheets of Dr
Solomon's Group PLC and its subsidiaries (the "Company") as of May 31, 1997 and
May 31, 1996 and the related consolidated profit and loss accounts, cash flow
statements, statements of total recognized gains and losses and reconciliation
of movements in shareholders' funds for the year ended May 31, 1997 and the
period from February 7, 1996 (date of acquisition) until May 31, 1996 and the
consolidated profit and loss accounts, cash flow statements, statements of total
recognized gains and losses and reconciliations of movements in shareholders'
funds of its predecessor, S&S International Limited, and its subsidiaries ("S&S
International") for the period from June 1, 1995 until February 6, 1996, and the
year ended May 31, 1995, all expressed in pounds sterling. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

        In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the Company
at May 31, 1997 and May 31, 1996 and the results of its operations and cash
flows for the year ended May 31, 1997 and the period from February 7, 1996 (date
of acquisition) until May 31, 1996 and the results of the operations and its
cash flows of S&S International Limited and its subsidiaries for the year ended
May 31, 1995 and for the period from June 1, 1995 until February 6, 1996 in
conformity with generally accepted accounting principles in the United Kingdom
(which differ in certain significant respects from generally accepted accounting
principles in the United States of America - See note 28).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1.          BASIS OF PRESENTATION AND ACCOUNTING POLICIES

BASIS OF CONSOLIDATED FINANCIAL STATEMENTS

            The consolidated financial statements are prepared in conformity
with generally accepted accounting principles in the United Kingdom ("U.K.
GAAP"), which differ in certain material respects from generally accepted
accounting principles in the United States of America ("U.S. GAAP") - see note
28.

            References to "Company" throughout the consolidated financial
statements are to Dr Solomon's Group PLC and its subsidiaries. References to
"S&S International" are to the predecessor, S&S International Limited, and its
subsidiaries.

BUSINESS

            The Company develops, markets and supports anti-virus software
programs for personal computers and PC networks. The Company's products provide
effective and easy to use software solutions to the risks posed by the
proliferation of new and increasingly sophisticated types of computer viruses.
The Company's principal product line is the "Dr Solomon's Anti-Virus Toolkit"
family of software programs (the "Toolkit").

CONSOLIDATION AND GOODWILL

            The consolidated financial statements include the accounts of both
the Company and S&S International for the periods specified. The difference
between consideration payable for the acquisition of interests in subsidiary
companies and the fair value of the assets acquired is written off directly to
other reserves in the year of acquisition.

CASH FLOW STATEMENT

            The adoption of Financial Reporting Standard ("FRS") no.1, "Cash
Flow Statement", has required the restatement of certain comparative
information.

ACCOUNTING CONVENTION

            The financial statements are prepared under the historical cost
convention.

FIXED ASSETS

            The cost of acquired fixed assets includes the purchase cost,
together with any incidental expenses of acquisition. The cost of purchased
software is capitalised and amortised from the implementation date over its
estimated useful economic life. The cost of software developed for internal use
is expensed in the period in which the cost is incurred.

            Depreciation of fixed assets is provided on cost on a straight-line
basis over the estimated useful lives of the respective assets, as follows.

<TABLE>
            <S>                                             <C>
            Short leasehold property and improvements       Over the remaining term of the lease
            Motor vehicles                                  Over 4 years 
            Fixtures, fittings and equipment                Between 2 and 5 years
            Software                                        Between 2 and 3 years
</TABLE>

STOCKS

            Stocks are stated at the lower of cost and net realisable value.
Cost is determined on a first-in first-out basis.

INVESTMENTS

            Current assets investments are stated at the lower of cost and,
where materially different, net realisable value.

DEFERRED TAXATION

            Deferred taxation is provided on timing differences, arising from
the different treatment of items for accounts and taxation purposes, which are
expected to reverse in the future, calculated at rates at which it is estimated
that tax will arise.


<PAGE>   7
FOREIGN EXCHANGE

            Profit and loss accounts in foreign currencies are translated into
sterling at the average rates of exchange prevailing for the relevant financial
period. Monetary assets and liabilities denominated in foreign currencies at the
period end are translated into sterling at the rate prevailing at the balance
sheet date. These differences are dealt with in the profit and loss account.
Exchange differences arising on the translation of the net investment in foreign
subsidiaries are dealt with as adjustments to reserves.

ACCOUNTING ESTIMATES

            The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the date
of the consolidated financial statements and the reported amounts of revenues
and expenses during the reported period. Accounting estimates have been employed
in these consolidated financial statements to determine reported amounts,
including realisability of debtors and other assets and the useful lives of
fixed assets. Actual results could differ from those estimates.

REVENUE RECOGNITION

            The Company recognizes revenues from product licenses and update
services (both of which include post-contract support) on a straight-line basis
over the term of the contracted service (usually one, two or three years in the
case of product licenses and one year in the case of update services).

            The Company recognizes 50% of the revenues from the sale of
boxed-products which include an update service at the time of sale and the
remaining 50% evenly over the term of the update service (including
post-contract support) included in a sale (normally one year). For those boxed
products not including an update service, revenue is recognized at time of sale.

LEASES

            Operating lease rentals are charged to profit and loss in equal
annual amounts over the lease term.

PENSION COSTS

            The Company operates defined contribution pension schemes. The
pension cost charge represents contributions paid by the Company to the funds on
an accruals basis.

RESEARCH AND DEVELOPMENT AND SOFTWARE DEVELOPMENT COSTS

            Research and development expenditure and software development costs
are charged to the profit and loss account as incurred. Based on the Company's
product development process, technological feasibility is established upon
completion of a working model. Subsequent costs to the point at which the
product is ready for general release have not been significant and none of these
costs have been capitalized.

EARNINGS PER SHARE

            Earnings per share have not been computed for periods which relate
to S&S International, the predecessor of the Company, as such information is not
considered meaningful for a period over period comparison due to the different
capital structure of S&S International as compared to the Company.

            Earnings per share are based upon the weighted average number of
ordinary shares in issue throughout the period and are calculated on the profit
on ordinary activities after taxation and after other finance charges in respect
of non-equity shares, but before equity dividends.

2.          ANALYSES OF TURNOVER, OPERATING PROFIT/(LOSS) AND NET
            ASSETS/(LIABILITIES)

            Turnover represents amounts derived from product licenses, sales of
boxed-products and providing updates to boxed-product purchasers, and royalty
income.

            The geographical analysis of turnover by destination of sales is as
follows:

            The high rates of effective taxation are due primarily to the losses
incurred in the U.S. which could not be offset against U.K. profits for taxation
purposes and to the accelerated depreciation policy relating to fixed assets
compared to allowances for taxation purposes and the timing differences on the
deferred revenue, for which no deferred tax asset is recognized in accordance
with U.K. GAAP.

            There are no deferred tax liabilities, provided or unprovided, at
May 31, 1995, 1996 or 1997.

            7,293,000 redeemable preference shares with par value 10 pence each
were authorised and issued on February 6, 1996 in connection with the
acquisition of S&S International. The shares were issued at a subscription price
of L. 1 each, giving rise to a total share premium of L. 6,564,000. These shares
were redeemed on December 2, 1996 at a premium of L. 1,167,000 of which L.
467,000 had been accrued at May 31, 1996.

            In September, October and November 1996, a total of 10,940,000 C
Ordinary shares of 1p each were issued to the Trustee, Bank of Scotland Trust
Company (International) Limited in order to satisfy options granted to the
Company's employees and to Dr Alan Solomon pursuant to the Dr Solomon's Group
Share Option Scheme.

            On November 25, 1996, by a special resolution at an Extraordinary
General Meeting, the authorised share capital of the Company was increased from
L. 435,000 to L. 582,318 by the creation of 14,731,800
Ordinary shares of 1p each. On December 2, 1996, the Company issued 11,970,000
new Ordinary shares of 1p each which the U.S. and European underwriters placed
with investors in the form of 3,990,000 American Depositary Shares ("ADSs")
(each ADS representing three new Ordinary shares). The public offering price was
$17.00 per ADS. The proceeds, net of expenses including underwriting
commissions, amounted to approximately L. 36.0 million.

            On November 25, 1996, all the issued and unissued A, B and C
Ordinary shares were converted into one class of Ordinary shares of 1p each,
ranking parri passu.

            At May 31, 1997, options have been granted over the Company's shares
as follows:

            Under the Group Scheme, options have been granted over 10,940,000
Ordinary shares of 1p each at an exercise price of 1p each. Twenty five per cent
of each option became exercisable on May 26, 1997 and an additional 25% will
become exercisable on November 26 of each of 1997, 1998 and 1999. Options lapse
seven years after their date of grant. The shares over which options have been
granted are held by the Trustee of the S&S International Holdings Employee
Benefit Trust. No further options may be granted under the Group Scheme.

Company Share Option Scheme 1996 ("Company Scheme")

            The Company Scheme is approved by the U.K. Inland Revenue and is
administered by the Remuneration Committee of the Board of Directors. The
Committee may grant options to any employee of the Company, including full-time
directors, who works at least 25 hours per week. The exercise price may not be
less than the nominal value of the share and the market value as agreed with the
Inland Revenue. Options normally become exercisable on the third anniversary of
the date of grant and lapse on the tenth anniversary of the date of grant and if
the option holder is still an employee of the Company. Options may only be
granted to an individual such that the aggregate market value of options under
Inland Revenue approved schemes (excluding savings related schemes) to that
individual do not exceed L. 30,000.

            Options over 163,392 Ordinary shares were granted on April 19, 1997
at an option price of L. 5.17 per Ordinary share.

Executive Share Option Scheme 1996 ("Executive Scheme")

            The Executive Scheme is similar to the Company Scheme except that it
is not an Inland Revenue approved scheme and there is no limit on the market
value of the Ordinary shares over which an option may be granted.

            Options over 198,483 Ordinary shares were granted on April 19, 1997
at an option price of L. 5.17 per Ordinary share.

Savings Related Option Scheme ("Savings Related Scheme")

            The Savings Related Scheme is approved by the U.K. Inland Revenue
and is administered by the Remuneration Committee of the Board of Directors. The
Committee may invite any employee of the Company to participate in a grant of
options. Options are linked to a contractual savings scheme to save between L. 5
and L. 250 per month. Participants may withdraw from the savings contract at any
time and are not obliged to exercise their option. The exercise price shall be
not less than the higher of the nominal value of the share and 80% of the market
value agreed with the Inland Revenue. Options may be exercised in the six month
period following the maturity date of the related savings contract which may be
the third, fifth or seventh anniversary of the commencement of the contract. No
options have been granted under the Savings Related Scheme.

28.         SUMMARY OF DIFFERENCES BETWEEN GENERALLY ACCEPTED ACCOUNTING 
            PRINCIPLES IN THE UNITED KINGDOM AND THE UNITED STATES

            The Consolidated Financial Statements are prepared in accordance
with generally accepted accounting principles in the United Kingdom ("U.K.
GAAP"), which differ in certain significant respects from those generally
accepted in the United States ("U.S. GAAP"). The differences that are
significant to Dr Solomon's Group PLC relate to the following items.

GOODWILL AND INTANGIBLE ASSETS

            Under U.K. GAAP, costs of acquisitions in excess of the fair value
of the attributable net assets of acquired businesses at the date of acquisition
may be capitalized or may be written off against shareholders' equity, either in
the financial year of acquisition or in a subsequent financial year. Dr
Solomon's Group PLC has written off such goodwill against shareholders' equity
in the financial year of acquisition.



<PAGE>   21

            Under U.S. GAAP, the excess of the purchase price over the net
assets acquired is allocated to goodwill and other intangible assets based on
the requirements of Accounting Principles Board Opinion No. 16 "Business
Combinations" (APB 16). The assets are capitalized and then amortized over a
term not to exceed 40 years.

PREFERENCE SHARES

            Under U.K. GAAP, redeemable preference shares are recorded in
shareholders' funds initially at the net proceeds received. This amount is
increased by the finance costs accrued over the life of the instruments and
reduced by dividends or other payments made in connection with the shares. The
total amount is separately disclosed as 'amounts attributable to non-equity
shareholders' at the bottom of the balance sheet.

            Under U.S. GAAP, redeemable preference shares are not included under
the general heading 'shareholders equity'. Finance costs accrued over the life
of the instruments are treated in the same manner as dividends on non-redeemable
preference shares and deducted from net income in determining net income
available to common shareholders.

DEFERRED TAXATION

            Under U.K. GAAP, deferred taxation is provided at the rates at which
the taxation is expected to become payable. No provision is made for amounts
which are not expected to become payable in the foreseeable future and no
account is taken of deferred tax assets in accordance with Statement of Standard
Accounting Practice 15.

            Under U.S. GAAP, deferred taxation is provided on all temporary
differences under the liability method at rates at which the taxation would be
payable in the relevant future year as prescribed by Statement of Financial
Accounting Standard ("SFAS") No. 109 - "Accounting for Income Taxes".

DIVIDENDS

            Under U.K. GAAP, dividends are included in the financial statements
when recommended by the Board of Directors to the shareholders.

            Under U.S. GAAP, dividends are not included in the financial
statements until declared by the Board of Directors.

EARNINGS PER SHARE

            Under U.K. GAAP earnings per share is based on the weighted average
number of ordinary shares in issue throughout the period and are calculated on
the profit on ordinary activities after taxation and after other finance charges
in respect of non-equity shares, but before equity dividends.

            Under U.S. GAAP income per share is based on the weighted average
number of ordinary shares in issue throughout the period and is calculated on
the net income for the period.

COMPENSATION EXPENSE

            The Company follows the provisions of Accounting Principles Board
Opinion no.25, "Accounting for stock issued to Employees" and is required to
recognize a non-cash compensation expense equal to the difference between the
exercise price of options granted under the Dr Solomon's Group Share Option
Scheme and the fair market value of the options at the time they were granted.
This amounted to L. 17,808 million in the quarter ended November 30, 1996. Under
U.S. GAAP, the Company is also required to recognize a non-cash compensation
expense of L. 2.0 million on the transfer of Investor Loan Stock to the
executive directors in the first quarter of the 1997 financial year.

CASH AND CASH EQUIVALENTS

            Under U.K. GAAP, cash is defined as cash in hand and deposits
repayable on demand, less overdrafts repayable on demand. Cash equivalents are
no longer defined. Deposits are classified as liquid investments.

            Under U.S. GAAP, cash equivalents consist of all deposits with an
original maturity of three months or less. Cash is not stated net of overdrafts,
instead these are presented within the financing section of the cash flow
statement.

CONSOLIDATED STATEMENTS OF CASH FLOWS

            The Consolidated Statements of Cash Flows prepared under U.K. GAAP
differ in certain presentational respects from the format required under SFAS
95-"Statement of Cash Flows". Under U.K. GAAP, a reconciliation of profit from
operations to cash

flows from operating activities is presented in a note, and cash paid for
interest and income taxes are presented separately from cash flows from
operating activities. Under SFAS 95, cash flows from operating activities are
based on net profit, include interest and income taxes, and are presented on the
face of the statement. U.K. GAAP requires cash and cash equivalents to be
presented net of overdrafts; SFAS 95 treats overdrafts within financing
activities.

            A reconciliation between the consolidated statements of cash flows
presented in accordance with U.K. GAAP and U.S. GAAP is set out below:

mainly to the non-deductibility for U.K. tax purposes of the amortization of
goodwill and intangible assets.

ended May 31, 1997, the net valuation allowance was increased to provide for the
gross deferred tax assets arising in the U.S.
