                            Network Associates, Inc.

                            1997 Stock Incentive Plan
                        (as amended through May 25, 2000)


ARTICLE 1. INTRODUCTION

        The Plan was adopted by the Board effective December 1, 1997. The
purpose of the Plan is to promote the long-term success of the Company and the
creation of stockholder value by (a) encouraging Employees, Outside Directors
and Consultants to focus on critical long-range objectives, (b) encouraging the
attraction and retention of Employees, Outside Directors and Consultants with
exceptional qualifications and (c) linking Employees, Outside Directors and
Consultants directly to stockholder interests through increased stock ownership.
The Plan seeks to achieve this purpose by providing for Awards in the form of
Restricted Shares, Stock Units, Options (which may constitute incentive stock
options or nonstatutory stock options) or stock appreciation rights.

        The Plan shall be governed by, and construed in accordance with, the
laws of the State of Delaware (except their choice-of-law provisions).

ARTICLE 2. ADMINISTRATION

        2.1 COMMITTEE COMPOSITION. The Plan shall be administered by the
Committee. The Committee shall consist exclusively of two or more directors of
the Company, who shall be appointed by the Board. In addition, the composition
of the Committee shall satisfy:

            (a) Such requirements as the Securities and Exchange Commission may
        establish for administrators acting under plans intended to qualify for
        exemption under Rule 16b-3 (or its successor) under the Exchange Act;
        and

            (b) Such requirements as the Internal Revenue Service may establish
        for outside directors acting under plans intended to qualify for
        exemption under section 162(m)(4)(C) of the Code.

The Board may also appoint one or more separate committees of the Board, each
composed of one or more directors of the Company who need not satisfy the
foregoing requirements, who may administer the Plan with respect to Employees
and Consultants who are not considered officers or directors of the Company
under section 16 of the Exchange Act, may grant Awards under the Plan to such
Employees and Consultants and may determine all terms of such Awards.

        2.2 COMMITTEE RESPONSIBILITIES. The Committee shall (a) select the
Employees, Outside Directors and Consultants who are to receive Awards under the
Plan, (b) determine the type,

<PAGE>   6

number, vesting requirements and other features and conditions of such Awards,
(c) interpret the Plan and (d) make all other decisions relating to the
operation of the Plan. The Committee may adopt such rules or guidelines as it
deems appropriate to implement the Plan. The Committee's determinations under
the Plan shall be final and binding on all persons.

ARTICLE 3. SHARES AVAILABLE FOR GRANTS

        3.1 BASIC LIMITATION. Common Shares issued pursuant to the Plan may be
authorized but unissued shares or treasury shares. The aggregate number of
Options, SARs, Stock Units and Restricted Shares awarded under the Plan shall
not exceed (a) 22,480,000 plus (b) the additional Common Shares described in
Section 3.2. The limitation of this Section 3.1 shall be subject to adjustment
pursuant to Article 10.

        3.2 ADDITIONAL SHARES. If Restricted Shares, Stock Units, Options or
SARs granted under this Plan or the Predecessor Plan are forfeited or if Options
or SARs granted under this Plan or the Predecessor Plan terminate for any other
reason before being exercised, then the corresponding Common Shares shall become
available for Awards under this Plan. If Stock Units are settled, then only the
number of Common Shares (if any) actually issued in settlement of such Stock
Units shall reduce the number available under Section 3.1 and the balance shall
again become available for Awards under the Plan. If SARs are exercised, then
only the number of Common Shares (if any) actually issued in settlement of such
SARs shall reduce the number available under Section 3.1 and the balance shall
again become available for Awards under the Plan. The foregoing notwithstanding,
the aggregate number of Common Shares that may be issued under the Plan upon the
exercise of ISOs shall not be increased when Restricted Shares are forfeited.

        3.3 DIVIDEND EQUIVALENTS. Any dividend equivalents paid or credited
under the Plan shall not be applied against the number of Restricted Shares,
Stock Units, Options or SARs available for Awards, whether or not such dividend
equivalents are converted into Stock Units.

ARTICLE 4. ELIGIBILITY

        4.1 INCENTIVE STOCK OPTIONS. Only Employees who are common-law employees
of the Company, a Parent or a Subsidiary on the date of grant shall be eligible
for the grant of ISOs. In addition, an Employee who owns more than 10% of the
total combined voting power of all classes of outstanding stock of the Company
or any of its Parents or Subsidiaries shall not be eligible for the grant of an
ISO unless the requirements set forth in section 422(c)(6) of the Code are
satisfied.

        4.2 OTHER GRANTS. Only Employees, Outside Directors and Consultants
shall be eligible for the grant of Restricted Shares, Stock Units, NSOs or SARs.

        4.3 PROSPECTIVE EMPLOYEES AND CONSULTANTS. For purposes of this Article
4, (a) "Employees" shall include prospective Employees to whom Awards are
granted in connection with written offers of employment from the Company, a
Parent or a Subsidiary and (b) "Consultants" shall include prospective
Consultants to whom Awards are granted in connection with written offers of
engagement from the Company, a Parent or a Subsidiary. If an ISO is granted

                                      -2-
<PAGE>   7

to a prospective Employee, the date when his or her service as an Employee
commences shall be deemed to be the date of grant of such ISO for all purposes
under the Plan (including, without limitation, Section 5.3). No Award granted to
a prospective Employee or prospective Consultant shall become exercisable or
vested unless and until his or her service as an Employee or Consultant
commences.

ARTICLE 5. OPTIONS

        5.1 STOCK OPTION AGREEMENT. Each grant of an Option under the Plan shall
be evidenced by a Stock Option Agreement between the Optionee and the Company.
Such Option shall be subject to all applicable terms of the Plan and may be
subject to any other terms that are not inconsistent with the Plan. The Stock
Option Agreement shall specify whether the Option is an ISO or an NSO. The
provisions of the various Stock Option Agreements entered into under the Plan
need not be identical. Options may be granted in consideration of a reduction in
the Optionee's other compensation. A Stock Option Agreement may provide that a
new Option will be granted automatically to the Optionee when he or she
exercises a prior Option and pays the Exercise Price in the form described in
Section 6.2.

        5.2 NUMBER OF SHARES. Each Stock Option Agreement shall specify the
number of Common Shares subject to the Option and shall provide for the
adjustment of such number in accordance with Article 10. Options granted to any
Optionee in a single fiscal year of the Company shall not cover more than
1,000,000 Common Shares, except that Options granted to a new Employee in the
fiscal year of the Company in which his or her service as an Employee first
commences shall not cover more than 1,500,000 Common Shares. The limitations set
forth in the preceding sentence shall be subject to adjustment in accordance
with Article 10.

        5.3 EXERCISE PRICE. Each Stock Option Agreement shall specify the
Exercise Price; provided that the Exercise Price under an ISO shall in no event
be less than 100% of the Fair Market Value of a Common Share on the date of
grant and the Exercise Price under an NSO shall in no event be less than 85% of
the Fair Market Value of a Common Share on the date of grant. In the case of an
NSO, a Stock Option Agreement may specify an Exercise Price that varies in
accordance with a predetermined formula while the NSO is outstanding.

        5.4 EXERCISABILITY AND TERM. Each Stock Option Agreement shall specify
the date or event when all or any installment of the Option is to become
exercisable. The Stock Option Agreement shall also specify the term of the
Option; provided that the term of an ISO shall in no event exceed 10 years from
the date of grant. A Stock Option Agreement may provide for accelerated
exercisability in the event of the Optionee's death, disability or retirement or
other events and may provide for expiration prior to the end of its term in the
event of the termination of the Optionee's service. Options may be awarded in
combination with SARs, and such an Award may provide that the Options will not
be exercisable unless the related SARs are forfeited.

        5.5 EFFECT OF TRANSFER OF CONTROL. The Committee may determine, at the
time of granting an Option or thereafter, that such Option shall become
exercisable as to all or part of the Common Shares subject to such Option in the
event that a Transfer of Control occurs with respect to

                                      -3-
<PAGE>   8

the Company, except that the exercisability of an ISO shall not be accelerated
without the Optionee's written consent. In addition, a separate agreement
between the Optionee and the Company may provide that such Optionee's Options
shall become exercisable as to all or part of the Common Shares subject to such
Options in the event that a Transfer of Control occurs with respect to the
Company.

        5.6 SUBSTITUTION OF OPTIONS. The Committee may accept the cancellation
of outstanding options granted by another issuer in return for the grant of new
Options under the Plan for the same or a different number of Common Shares and
at the same or a different Exercise Price.

        5.7 BUYOUT PROVISIONS. The Committee may at any time (a) offer to buy
out for a payment in cash or cash equivalents an Option previously granted or
(b) authorize an Optionee to elect to cash out an Option previously granted, in
either case at such time and based upon such terms and conditions as the
Committee shall establish.

ARTICLE 6. PAYMENT FOR OPTION SHARES

        6.1 GENERAL RULE. The entire Exercise Price of Common Shares issued upon
exercise of Options shall be payable in cash or cash equivalents at the time
when such Common Shares are purchased, except as follows:

            (a) In the case of an ISO granted under the Plan, payment shall be
        made only pursuant to the express provisions of the applicable Stock
        Option Agreement. The Stock Option Agreement may specify that payment
        may be made in any form(s) described in this Article 6.

            (b) In the case of an NSO, the Committee may at any time accept
        payment in any form(s) described in this Article 6.

        6.2 SURRENDER OF STOCK. To the extent that this Section 6.2 is
applicable, all or any part of the Exercise Price may be paid by surrendering,
or attesting to the ownership of, Common Shares that are already owned by the
Optionee. Such Common Shares shall be valued at their Fair Market Value on the
date when the new Common Shares are purchased under the Plan. The Optionee shall
not surrender, or attest to the ownership of, Common Shares in payment of the
Exercise Price if such action would cause the Company to recognize compensation
expense (or additional compensation expense) with respect to the Option for
financial reporting purposes.

        6.3 EXERCISE/SALE. To the extent that this Section 6.3 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Company) an irrevocable direction to a
securities broker approved by the Company to sell all or part of the Common
Shares being purchased under the Plan and to deliver all or part of the sales
proceeds to the Company.

        6.4 EXERCISE/PLEDGE. To the extent that this Section 6.4 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the

                                      -4-
<PAGE>   9

Company) an irrevocable direction to pledge all or part of the Common Shares
being purchased under the Plan to a securities broker or lender approved by the
Company, as security for a loan, and to deliver all or part of the loan proceeds
to the Company.

        6.5 PROMISSORY NOTE. To the extent that this Section 6.5 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Company) a full-recourse promissory
note; provided that the par value of the Common Shares being purchased under the
Plan shall be paid in cash or cash equivalents.

        6.6 OTHER FORMS OF PAYMENT. To the extent that this Section 6.6 is
applicable, all or any part of the Exercise Price and any withholding taxes may
be paid in any other form that is consistent with applicable laws, regulations
and rules.

ARTICLE 7. STOCK APPRECIATION RIGHTS

        7.1 SAR AGREEMENT. Each grant of an SAR under the Plan shall be
evidenced by an SAR Agreement between the Optionee and the Company. Such SAR
shall be subject to all applicable terms of the Plan and may be subject to any
other terms that are not inconsistent with the Plan. The provisions of the
various SAR Agreements entered into under the Plan need not be identical. SARs
may be granted in consideration of a reduction in the Optionee's other
compensation.

        7.2 NUMBER OF SHARES. Each SAR Agreement shall specify the number of
Common Shares to which the SAR pertains and shall provide for the adjustment of
such number in accordance with Article 10. SARs granted to any Optionee in a
single calendar year shall in no event pertain to more than 1,000,000 Common
Shares, except that SARs granted to a new Employee in the fiscal year of the
Company in which his or her service as an Employee first commences shall not
pertain to more than 1,500,000 Common Shares. The limitations set forth in the
preceding sentence shall be subject to adjustment in accordance with Article 10.

        7.3 EXERCISE PRICE. Each SAR Agreement shall specify the Exercise Price.
An SAR Agreement may specify an Exercise Price that varies in accordance with a
predetermined formula while the SAR is outstanding.

        7.4 EXERCISABILITY AND TERM. Each SAR Agreement shall specify the date
when all or any installment of the SAR is to become exercisable. The SAR
Agreement shall also specify the term of the SAR. An SAR Agreement may provide
for accelerated exercisability in the event of the Optionee's death, disability
or retirement or other events and may provide for expiration prior to the end of
its term in the event of the termination of the Optionee's service. SARs may be
awarded in combination with Options, and such an Award may provide that the SARs
will not be exercisable unless the related Options are forfeited. An SAR may be
included in an ISO only at the time of grant but may be included in an NSO at
the time of grant or thereafter. An SAR granted under the Plan may provide that
it will be exercisable only in the event of a Transfer of Control.

                                      -5-
<PAGE>   10
        7.5 EFFECT OF TRANSFER OF CONTROL. The Committee may determine, at the
time of granting an SAR or thereafter, that such SAR shall become exercisable as
to all or part of the Common Shares subject to such SAR in the event that a
Transfer of Control occurs with respect to the Company. In addition, a separate
agreement between the Optionee and the Company may provide that such Optionee's
SARs shall become exercisable as to all or part of the Common Shares subject to
such SARs in the event that a Transfer of Control occurs with respect to the
Company.

        7.6 EXERCISE OF SARS. Upon exercise of an SAR, the Optionee (or any
person having the right to exercise the SAR after his or her death) shall
receive from the Company (a) Common Shares, (b) cash or (c) a combination of
Common Shares and cash, as the Committee shall determine. The amount of cash
and/or the Fair Market Value of Common Shares received upon exercise of SARs
shall, in the aggregate, be equal to the amount by which the Fair Market Value
(on the date of surrender) of the Common Shares subject to the SARs exceeds the
Exercise Price. If, on the date when an SAR expires, the Exercise Price under
such SAR is less than the Fair Market Value on such date but any portion of such
SAR has not been exercised or surrendered, then such SAR shall automatically be
deemed to be exercised as of such date with respect to such portion.

        7.7 MODIFICATION OR ASSUMPTION OF SARS. Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding SARs or may accept
the cancellation of outstanding SARs (whether granted by the Company or by
another issuer) in return for the grant of new SARs for the same or a different
number of shares and at the same or a different exercise price. The foregoing
notwithstanding, no modification of an SAR shall, without the consent of the
Optionee, alter or impair his or her rights or obligations under such SAR.

ARTICLE 8. RESTRICTED SHARES

        8.1 RESTRICTED STOCK AGREEMENT. Each grant of Restricted Shares under
the Plan shall be evidenced by a Restricted Stock Agreement between the
recipient and the Company. Such Restricted Shares shall be subject to all
applicable terms of the Plan and may be subject to any other terms that are not
inconsistent with the Plan. The provisions of the various Restricted Stock
Agreements entered into under the Plan need not be identical. Restricted Shares
may be granted in consideration of a reduction in the recipient's other
compensation.

        8.2 PAYMENT FOR AWARDS. To the extent that an Award is granted in the
form of newly issued Restricted Shares, the Award recipient, as a condition to
the grant of such Award, shall be required to pay the Company in cash or cash
equivalents an amount equal to the par value of such Restricted Shares. To the
extent that an Award is granted in the form of Restricted Shares from the
Company's treasury, no cash consideration shall be required of the Award
recipients. Any amount not paid in cash may be paid with a full-recourse
promissory note.

        8.3 VESTING CONDITIONS. Each Award of Restricted Shares may or may not
be subject to vesting. Vesting shall occur, in full or in installments, upon
satisfaction of the conditions specified in the Restricted Stock Agreement. The
Committee may include among such conditions the requirement that the performance
of the Company or a business unit of the Company for a specified period of one
or more years equal or exceed a target determined in advance by the Committee.
Such

                                      -6-
<PAGE>   11

performance shall be determined by the Company's independent auditors. Such
target shall be based on one or more of the criteria set forth in Appendix A.
The Committee shall determine such target not later than the 90th day of such
period. In no event shall the number of Restricted Shares which are subject to
performance-based vesting conditions and which are granted to any Participant in
a single calendar year exceed 300,000, subject to adjustment in accordance with
Article 10. A Restricted Stock Agreement may provide for accelerated vesting in
the event of the Participant's death, disability or retirement or other events.

        8.4 EFFECT OF TRANSFER OF CONTROL. The Committee may determine, at the
time of granting Restricted Shares or thereafter, that all or part of such
Restricted Shares shall become vested in the event that a Transfer of Control
occurs with respect to the Company. In addition, a separate agreement between
the Participant and the Company may provide that all or part of such
Participant's Restricted Shares shall become vested in the event that a Transfer
of Control occurs with respect to the Company.

        8.5 VOTING AND DIVIDEND RIGHTS. The holders of Restricted Shares awarded
under the Plan shall have the same voting, dividend and other rights as the
Company's other stockholders. A Restricted Stock Agreement, however, may require
that the holders of Restricted Shares invest any cash dividends received in
additional Restricted Shares. Such additional Restricted Shares shall be subject
to the same conditions and restrictions as the Award with respect to which the
dividends were paid.

ARTICLE 9. STOCK UNITS

        9.1 STOCK UNIT AGREEMENT. Each grant of Stock Units under the Plan shall
be evidenced by a Stock Unit Agreement between the recipient and the Company.
Such Stock Units shall be subject to all applicable terms of the Plan and may be
subject to any other terms that are not inconsistent with the Plan. The
provisions of the various Stock Unit Agreements entered into under the Plan need
not be identical. Stock Units may be granted in consideration of a reduction in
the recipient's other compensation.

        9.2 PAYMENT FOR AWARDS To the extent that an Award is granted in the
form of Stock Units, no cash consideration shall be required of the Award
recipients.

        9.3 VESTING CONDITIONS. Each Award of Stock Units may or may not be
subject to vesting. Vesting shall occur, in full or in installments, upon
satisfaction of the conditions specified in the Stock Unit Agreement. The
Committee may include among such conditions the requirement that the performance
of the Company or a business unit of the Company for a specified period of one
or more years equal or exceed a target determined in advance by the Committee.
Such performance shall be determined by the Company's independent auditors. Such
target shall be based on one or more of the criteria set forth in Appendix A.
The Committee shall determine such target not later than the 90th day of such
period. In no event shall the number of Stock Units which are subject to
performance-based vesting conditions and which are granted to any Participant in
a single calendar year exceed 300,000, subject to adjustment in accordance with
Article 10. A Stock Unit Agreement

                                      -7-
<PAGE>   12

may provide for accelerated vesting in the event of the Participant's death,
disability or retirement or other events.

        9.4 EFFECT OF TRANSFER OF CONTROL. The Committee may determine, at the
time of granting Stock Units or thereafter, that all or part of such Stock Units
shall become vested in the event that a Transfer of Control occurs with respect
to the Company. In addition, a separate agreement between the Participant and
the Company may provide that all or part of such Participant's Stock Units shall
become vested in the event that a Transfer of Control occurs with respect to the
Company.

        9.5 VOTING AND DIVIDEND RIGHTS. The holders of Stock Units shall have no
voting rights. Prior to settlement or forfeiture, any Stock Unit awarded under
the Plan may, at the Committee's discretion, carry with it a right to dividend
equivalents. Such right entitles the holder to be credited with an amount equal
to all cash dividends paid on one Common Share while the Stock Unit is
outstanding. Dividend equivalents may be converted into additional Stock Units.
Settlement of dividend equivalents may be made in the form of cash, in the form
of Common Shares, or in a combination of both. Prior to distribution, any
dividend equivalents which are not paid shall be subject to the same conditions
and restrictions as the Stock Units to which they attach.

        9.6 FORM AND TIME OF SETTLEMENT OF STOCK UNITS. Settlement of vested
Stock Units may be made in the form of (a) cash, (b) Common Shares or (c) any
combination of both, as determined by the Committee. The actual number of Stock
Units eligible for settlement may be larger or smaller than the number included
in the original Award, based on predetermined performance factors. Methods of
converting Stock Units into cash may include (without limitation) a method based
on the average Fair Market Value of Common Shares over a series of trading days.
Vested Stock Units may be settled in a lump sum or in installments. The
distribution may occur or commence when all vesting conditions applicable to the
Stock Units have been satisfied or have lapsed, or it may be deferred to any
later date. The amount of a deferred distribution may be increased by an
interest factor or by dividend equivalents. Until an Award of Stock Units is
settled, the number of such Stock Units shall be subject to adjustment pursuant
to Article 10.

        9.7 DEATH OF RECIPIENT. Any Stock Units Award that becomes payable after
the recipient's death shall be distributed to the recipient's beneficiary or
beneficiaries. Each recipient of a Stock Units Award under the Plan shall
designate one or more beneficiaries for this purpose by filing the prescribed
form with the Company. A beneficiary designation may be changed by filing the
prescribed form with the Company at any time before the Award recipient's death.
If no beneficiary was designated or if no designated beneficiary survives the
Award recipient, then any Stock Units that become payable after the recipient's
death shall be distributed to the recipient's estate.

        9.8 CREDITORS' RIGHTS. A holder of Stock Units shall have no rights
other than those of a general creditor of the Company. Stock Units represent an
unfunded and unsecured obligation of the Company, subject to the terms and
conditions of the applicable Stock Unit Agreement.

ARTICLE 10. PROTECTION AGAINST DILUTION

        10.1 ADJUSTMENTS. In the event of a subdivision of the outstanding
Common Shares, a declaration of a dividend payable in Common Shares, a
declaration of a dividend payable in a form other than Common Shares in an
amount that has a material effect on the price of Common Shares, a combination
or consolidation of the outstanding Common Shares (by reclassification or
otherwise) into a lesser number of Common Shares, a recapitalization, a spin-off
or a similar occurrence, the Committee shall make such adjustments as it, in its
sole discretion, deems appropriate in one or more of:

            (a) The number of Options, SARs, Restricted Shares and Stock Units
        available for future Awards under Article 3;

            (b) The limitations set forth in Sections 5.2, 7.2, 8.3 and 9.3;

            (c) The number of Common Shares covered by each outstanding Option
        and SAR;

            (d) The Exercise Price under each outstanding Option and SAR; or

            (e) The number of Stock Units included in any prior Award which has
        not yet been settled.

Except as provided in this Article 10, a Participant shall have no rights by
reason of any issue by the Company of stock of any class or securities
convertible into stock of any class, any subdivision or consolidation of shares
of stock of any class, the payment of any stock dividend or any other increase
or decrease in the number of shares of stock of any class.

        10.2 DISSOLUTION OR LIQUIDATION. To the extent not previously exercised
or settled, Options, SARs and Stock Units shall terminate immediately prior to
the dissolution or liquidation of the Company.

        10.3 REORGANIZATIONS. In the event that the Company is a party to a
merger or other reorganization, outstanding Awards shall be subject to the
agreement of merger or reorganization. Such agreement shall provide for (a) the
continuation of the outstanding Awards by the Company, if the Company is a
surviving corporation, (b) the assumption of the outstanding Awards by the
surviving corporation or its parent or subsidiary, (c) the substitution by the
surviving corporation or its parent or subsidiary of its own awards for the
outstanding Awards, (d) full exercisability or vesting and accelerated
expiration of the outstanding Awards or (e) settlement of the full value of the
outstanding Awards in cash or cash equivalents followed by cancellation of such
Awards.

Participant to:

                                      -9-
<PAGE>   14

               (a) Have cash that otherwise would be paid to such Participant as
        a result of the exercise of an SAR or the settlement of Stock Units
        credited to a deferred compensation account established for such
        Participant by the Committee as an entry on the Company's books;

               (b) Have Common Shares that otherwise would be delivered to such
        Participant as a result of the exercise of an Option or SAR converted
        into an equal number of Stock Units; or

               (c) Have Common Shares that otherwise would be delivered to such
        Participant as a result of the exercise of an Option or SAR, or the
        settlement of Stock Units, converted into amounts credited to a deferred
        compensation account established for such Participant by the Committee
        as an entry on the Company's books. Such amounts shall be determined by
        reference to the Fair Market Value of such Common Shares as of the date
        when they otherwise would have been delivered to such Participant.

A deferred compensation account established under this Article 11 may be
credited with interest or other forms of investment return, as determined by the
Committee. A Participant for whom such an account is established shall have no
rights other than those of a general creditor of the Company. Such an account
shall represent an unfunded and unsecured obligation of the Company and shall be
subject to the terms and conditions of the applicable agreement between such
Participant and the Company. If the deferral or conversion of Awards is
permitted or required, the Committee (in its sole discretion) may establish
rules, procedures and forms pertaining to such Awards, including (without
limitation) the settlement of deferred compensation accounts established under
this Article 11.

ARTICLE 12. AWARDS UNDER OTHER PLANS

        The Company may grant awards under other plans or programs. Such awards
may be settled in the form of Common Shares issued under this Plan. Such Common
Shares shall be treated for all purposes under the Plan like Common Shares
issued in settlement of Stock Units and shall, when issued, reduce the number of
Common Shares available under Article 3.

ARTICLE 13. LIMITATION ON RIGHTS

        13.1 RETENTION RIGHTS. Neither the Plan nor any Award granted under the
Plan shall be deemed to give any individual a right to remain an Employee,
Outside Director or Consultant. The Company and its Parents, Subsidiaries and
Affiliates reserve the right to terminate the service of any Employee or
Consultant at any time, with or without cause, subject to applicable laws and a
written employment agreement (if any).

        13.2 STOCKHOLDERS' RIGHTS. A Participant shall have no dividend rights,

entitled to receive such Common Shares by filing any required notice of

                                      -10-

issuance of such Common Shares, to their registration, qualification or listing
or to an exemption from registration, qualification or listing.

ARTICLE 14. WITHHOLDING TAXES

obligations that arise in connection with the Plan. The Company shall not be
required to issue any Common Shares or make any cash payment under the Plan
until such obligations are satisfied.

        14.2 SHARE WITHHOLDING. The Committee may permit a Participant to
satisfy all or part of his or her withholding or income tax obligations by
having the Company withhold all or a portion of any Common Shares that otherwise
would be issued to him or her or by surrendering all or a portion of any Common
Shares that he or she previously acquired. Such Common Shares shall be valued at
their Fair Market Value on the date when taxes otherwise would be withheld in
cash.

                                   APPENDIX B

                        OPTION GRANTS IN THE NETHERLANDS

        This Appendix B to the Network Associates, Inc. 1997 Stock Incentive
Plan (the "Plan") sets forth special rules under which Options may be granted to
Employees and Consultants in The Netherlands who are subject to Dutch tax laws
on the date of option grant, as specified in the applicable Stock Option
Agreement (the "Date of Option Grant"). Such Employees and Consultants are
referred to herein as the "Dutch Residents." To the extent that the rules in
this Appendix B are not consistent with the provisions of the Plan, this
Appendix B shall govern. In all other respects, the provisions of the Plan
(including its definitions) shall apply to this Appendix B.

        1. EXERCISE PRICE. The Exercise Price of an Option granted to a Dutch
Resident, as specified in the applicable Stock Option Agreement (the "Exercise
Price"), shall not be less than the Fair Market Value of a Common Share on the
Date of Option Grant.

        2. EXERCISABILITY. Options granted to a Dutch Resident shall be
exercisable immediately upon grant.

        3. RIGHT OF REPURCHASE. If a Dutch Resident ceases to be an Employee or
Consultant for any reason before the fourth anniversary of the Date of Option
Grant, the Company shall have the right to repurchase all or a portion of the
Common Shares (if any) that such Dutch Resident acquired by exercising such
Option. The repurchase price per share shall be equal to the Exercise Price per
share. Prior to the first anniversary of the Date of Option Grant, the right of
repurchase shall apply to all of the Common Shares that the Dutch Resident
acquired by exercising the Option. After 12 months of continuous service as an
Employee or Consultant following the Date of Option Grant, the right of
repurchase shall lapse with respect to 25% of the Common Shares subject to the
Option. Thereafter, the right of repurchase shall lapse with respect to an
additional 2.08333% of the Common Shares subject to the Option for each
additional month of continuous service as an Employee or Consultant. A Dutch
Resident shall not sell, pledge or otherwise transfer the Common Shares that he
or she acquired by exercising an Option as long as such Common Shares remain
subject to the Company's right of repurchase.

        4. EXPIRATION DATE. All Options granted to Dutch Residents shall expire
on the fifth anniversary of the Date of Option Grant.
