                            Networks Associates, Inc.

                            1997 Stock Incentive Plan
                        (as amended through May 15, 2002)

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>

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) 32,475,000 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>

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>

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>

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>

        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>

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>

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.

                                                                             -8-
<PAGE>

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.

ARTICLE 11.    DEFERRAL OF AWARDS

        The Committee (in its sole discretion) may permit or require a
Participant to:

                                      -9-
<PAGE>

            (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

the Company and its stockholders by providing an incentive to attract, retain
and reward Eligible Employees of the Participating Company Group and by
motivating such persons to contribute to the growth and profitability of the

opportunity to acquire a proprietary interest in the Company through the

stock purchase plan" under Section 423 of the Code (including any amendments or
replacements of such section), and the Plan shall be so construed. In addition,
this Plan authorizes the grant of Purchase Rights which do not qualify under
Section 423 of the Code pursuant to rules, procedures or sub-plans adopted by
the Board designed to achieve desired tax or other objectives in particular
locations outside the United States.

1.3 TERM OF PLAN. The Plan shall continue in effect until the earlier of its
termination by the Board or the date on which all of the shares of Stock
available for issuance under the Plan have been issued.

connection with the Plan, or any right granted hereunder, and against all
amounts paid by them in settlement thereof (provided such settlement is approved
by independent legal counsel selected by the Company) or paid by them in
satisfaction of a judgment in any such action, suit or proceeding, except in
relation to matters as to which it shall be adjudged in such action, suit or
proceeding that such person is liable for gross negligence, bad faith or
intentional misconduct in duties; provided, however, that within sixty (60) days
after the institution of such action, suit or proceeding, such person shall
offer to the Company, in writing, the opportunity at its own expense to handle
and defend the same.

        4. SHARES SUBJECT TO PLAN.

           4.1 MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be 2,000,000, and shall consist of authorized
but unissued or reacquired shares of Stock, or any combination thereof. If an
outstanding Purchase Right for any reason expires or is terminated or canceled,
the shares of Stock allocable to the unexercised portion of that Purchase Right
shall again be available for issuance under the Plan.

           4.2 ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company, or
in the event of any merger (including a merger effected for the purpose of
changing the Company's domicile), sale of assets or other reorganization in
which the Company is a party, appropriate adjustments shall be made in the
number and class of shares subject to the Plan and each Purchase Right, and in
the Purchase Price. If a majority of the

                                                                               5
<PAGE>

shares of the same class as the shares subject to outstanding Purchase Rights
are exchanged for, converted into, or otherwise become (whether or not pursuant
to an Ownership Change Event) shares of another corporation (the "NEW SHARES"),
the Board may unilaterally amend the outstanding Purchase Rights to provide that
such Purchase Rights are exercisable for New Shares. In the event of any such
amendment, the number of shares subject to, and the Purchase Price of, the
outstanding Purchase Rights shall be adjusted in a fair and equitable manner, as
determined by the Board, in its discretion. Notwithstanding the foregoing, any
fractional share resulting from an adjustment pursuant to this Section 4.2 shall
be rounded down to the nearest whole number, and in no event may the Purchase
Price be decreased to an amount less than the par value, if any, of the stock
subject to the Purchase Right. The adjustments determined by the Board pursuant
to this Section 4.2 shall be final, binding and conclusive.

        5. ELIGIBILITY.

           5.1 EMPLOYEES ELIGIBLE TO PARTICIPATE. Each Employee of a
Participating Company is eligible to participate in the Plan and shall be deemed
an Eligible Employee, except the following excluded employees: (a) any Employee
who has not completed thirty (30) days of continuous employment with a
Participating Company as of the Offering Date, or (b) any Employee who is
customarily employed by the Participating Company Group for less then twenty
(20) hours per week unless, for Participants outside the United States, such
exclusion is not permitted under foreign law.

           5.2 EXCLUSION OF CERTAIN STOCKHOLDERS. Notwithstanding any provision
of the Plan to the contrary, no Employee shall be treated as an Eligible
Employee and granted a Purchase Right under the Plan if, immediately after such
grant, the Employee would own or hold options to purchase stock of the Company
or of any Parent Corporation or Subsidiary Corporation possessing five percent
(5%) or more of the total combined voting power or value of all classes of stock
of such corporation, as determined in accordance with Section 423(b)(3) of the
Code. For purposes of this Section 5.2, the attribution rules of Section 424(d)
of the Code shall apply in determining the stock ownership of such Employee.

           5.3 DETERMINATION BY COMPANY. The Company shall determine in good
faith and in the exercise of its discretion whether an individual has become or
has ceased to be an Employee or an Eligible Employee and the effective date of
such individual's attainment or termination of such status, as the case may be.
For purposes of an individual's participation in or other rights, if any, under
the Plan as of the time of the Company's determination, all such determinations
by the Company shall be final, binding and conclusive, notwithstanding that the
Company or any court of law or governmental agency subsequently makes a contrary
determination.

        6. OFFERINGS.

           6.1 OFFERING PERIODS. The Plan shall be implemented on and after the
Effective Date by sequential and overlapping Offerings of approximately twenty
four (24) months duration or such other duration as the Board shall determine
(an "OFFERING PERIOD"); provided, however, that the first Offering Period shall
commence on August 1, 2002 and end on or about July 31, 2004.

                                                                               6
<PAGE>

Subsequent Offering Periods shall commence on or about February 1 and August 1
of each year and end on or about the last days of the second January and July,
respectively, occurring thereafter. Notwithstanding the foregoing, the Board may
establish a different duration for one or more Offering Periods or different
commencing or ending dates for such Offering Periods; provided, however, that no
Offering Period may have a duration exceeding twenty-seven (27) months. If the
first or last day of an Offering Period is not a day on which the national
securities exchanges or Nasdaq Stock Market are open for trading, the Company
shall specify the trading day that will be deemed the first or last day, as the
case may be, of the Offering Period.

        6.2 PURCHASE PERIODS. Each Offering Period shall consist of four (4)
consecutive purchase periods of approximately six (6) months duration, or such
other number or duration as the Board shall determine (individually, a "PURCHASE
PERIOD"). A Purchase Period commencing on or about February 1 shall end on or
about the next July 31. A Purchase Period commencing on or about August 1 shall
end on or about the next January 31. Notwithstanding the foregoing, the Board
may establish a different duration for one or more Purchase Periods or different
commencing or ending dates for such Purchase Periods. If the first or last day
of a Purchase Period is not a day on which the national securities exchanges or
Nasdaq Stock Market are open for trading, the Company shall specify the trading
day that will be deemed the first or last day, as the case may be, of the
Purchase Period.

        7. PARTICIPATION IN THE PLAN.

           7.1 INITIAL PARTICIPATION. An Eligible Employee may become a
Participant in an Offering Period by delivering a properly completed
Subscription Agreement to the office designated by the Company not later than
the close of business for such office on the Subscription Date established by
the Company for that Offering Period. An Eligible Employee who does not deliver
a properly completed Subscription Agreement to the Company's designated office
on or before the Subscription Date for an Offering Period shall not participate
in the Plan for that Offering Period or for any subsequent Offering Period
unless the Eligible Employee subsequently delivers a properly completed
Subscription Agreement to the appropriate office of the Company on or before the
Subscription Date for such subsequent Offering Period. An Employee who becomes
an Eligible Employee after the Offering Date of an Offering Period shall not be
eligible to participate in that Offering Period but may participate in any
subsequent Offering Period provided the Employee is still an Eligible Employee
as of the Offering Date of such subsequent Offering Period.

        7.2 CONTINUED PARTICIPATION. A Participant shall automatically
participate in the next Offering Period commencing immediately after the final
Purchase Date of each Offering Period in which the Participant participates
provided that the Participant remains an Eligible Employee on the Offering Date
of the new Offering Period and has not either (a) withdrawn from the Plan
pursuant to Section 12.1 or (b) terminated employment as provided in Section 13.
A Participant who may automatically participate in a subsequent Offering Period,
as provided in this Section, is not required to deliver any additional
Subscription Agreement for the subsequent Offering Period in order to continue
participation in the Plan. However, a Participant may deliver a new Subscription
Agreement for a subsequent Offering Period in accordance with the procedures set
forth in Section

                                                                               7
<PAGE>

7.1 if the Participant desires to change any of the elections contained in the
Participant's then effective Subscription Agreement.

        8. RIGHT TO PURCHASE SHARES.

           8.1 GRANT OF PURCHASE RIGHT. Except as otherwise specified by the
Board prior to the Offering Date or of an Offering Period, on the Offering Date
of each Offering Period, each Participant in that Offering Period shall be
granted automatically a Purchase Right consisting of an option to purchase the
lesser of (a) that number of whole shares of Stock determined by dividing Fifty
Thousand Dollars ($50,000) by the Fair Market Value of a share of Stock on such
Offering Date or (b) ten thousand (10,000) shares of Stock. No Purchase Right
shall be granted on an Offering Date to any person who is not, on such Offering
Date, an Eligible Employee.

           8.2 CALENDAR YEAR PURCHASE LIMITATION. Notwithstanding any provision
of the Plan to the contrary, no Participant shall be granted a Purchase Right
which permits his or her right to purchase shares of Stock under the Plan to
accrue at a rate which, when aggregated with such Participant's rights to
purchase shares under all other employee stock purchase plans of a Participating
Company intended to meet the requirements of Section 423 of the Code, exceeds
Twenty-Five Thousand Dollars ($25,000) in Fair Market Value (or such other
limit, if any, as may be imposed by the Code) for each calendar year in which
such Purchase Right is outstanding at any time. For purposes of the preceding
sentence, the Fair Market Value of shares purchased during a given Offering
Period shall be determined as of the Offering Date for such Offering Period. The
limitation described in this Section shall be applied in conformance with
applicable regulations under Section 423(b)(8) of the Code.

        9. PURCHASE PRICE.

           The Purchase Price at which each share of Stock may be acquired in an
Offering Period upon the exercise of all or any portion of a Purchase Right
shall be established by the Board; provided, however, that the Purchase Price on
each Purchase Date shall not be less than eighty-five percent (85%) of the
lesser of (a) the Fair Market Value of a share of Stock on the Offering Date of
the Offering Period or (b) the Fair Market Value of a share of Stock on the
Purchase Date. Unless otherwise provided by the Board prior to the commencement
of an Offering Period, the Purchase Price on each Purchase Date during that
Offering Period shall be eighty-five percent (85%) of the lesser of (a) the Fair
Market Value of a share of Stock on the Offering Date of the Offering Period, or
(b) the Fair Market Value of a share of Stock on the Purchase Date.

       10. ACCUMULATION OF PURCHASE PRICE THROUGH PAYROLL DEDUCTION.

           Shares of Stock acquired pursuant to the exercise of all or any
portion of a Purchase Right may be paid for by means of payroll deductions from
the Participant's Compensation accumulated during the Offering Period for which
such Purchase Right was granted or, if authorized by the Board for Participants
outside the United States, by means of contribution other than payroll
deductions, subject to the following:

                                                                               8
<PAGE>

            10.1 AMOUNT OF PAYROLL DEDUCTIONS. Except as otherwise provided
herein, the amount to be deducted under the Plan from a Participant's
Compensation on each payday during an Offering Period shall be determined by the
Participant's Subscription Agreement. The Subscription Agreement shall set forth
the percentage of the Participant's Compensation to be deducted on each payday
during an Offering Period in whole percentages of not less than one percent (1%)
(except as a result of an election pursuant to Section 10.3 to stop payroll
deductions effective following the first payday during an Offering) or more than
ten percent (10%). The Board may change the foregoing limits on payroll
deductions effective as of any Offering Date.

            10.2 COMMENCEMENT OF PAYROLL DEDUCTIONS. Payroll deductions shall
commence on the first payday following the Offering Date and shall continue to
the end of the Offering Period unless sooner altered or terminated as provided
herein.

            10.3 ELECTION TO CHANGE OR STOP PAYROLL DEDUCTIONS. During an
Offering Period, a Participant may elect to increase or decrease the rate of or
to stop deductions from his or her Compensation by delivering to the Company's
designated office an amended Subscription Agreement authorizing such change on
or before the Change Notice Date, as defined below. A Participant who elects,
effective following the first payday of an Offering Period, to decrease the rate
of his or her payroll deductions to one percent (1%) shall nevertheless remain a
Participant in the current Offering Period unless such Participant withdraws
from the Plan as provided in Section 12.1. The "CHANGE NOTICE DATE" shall be the
day immediately prior to the beginning of the first pay period for which such
election is to be effective, unless a different date is established by the
Company and announced to the Participants.

            10.4 ADMINISTRATIVE SUSPENSION OF PAYROLL DEDUCTIONS. The Company
may, in its sole discretion, suspend a Participant's payroll deductions under
the Plan as the Company deems advisable to avoid accumulating payroll deductions
in excess of the amount that could reasonably be anticipated to purchase the
maximum number of shares of Stock permitted (a) under the Participant's Purchase
Right or (b) during a calendar year under the limit set forth in Section 8.2.
Payroll deductions shall be resumed at the rate specified in the Participant's
then effective Subscription Agreement at the beginning, respectively, of (a) the
next Offering Period the first Purchase Date of which falls in the following
calendar year, provided that the individual is a Participant in such Offering
Period or (b) the next Purchase Period the Purchase Date of which falls in the
following calendar year, unless the Participant has either withdrawn from the
Plan as provided in Section 12.1 or has ceased to be an Eligible Employee.

            10.5 PARTICIPANT ACCOUNTS. Individual bookkeeping accounts shall be
maintained for each Participant. All payroll deductions from a Participant's
Compensation shall be credited to such Participant's Plan account and shall be
deposited with the general funds of the Company unless prohibited by foreign law
for Participants outside the United States. All payroll deductions received or
held by the Company may be used by the Company for any corporate purpose.

            10.6 NO INTEREST PAID. Interest shall not be paid on sums deducted
from a Participant's Compensation pursuant to the Plan unless required by
foreign law for Participants outside the United States.

                                                                               9
<PAGE>

            10.7 VOLUNTARY WITHDRAWAL FROM PLAN ACCOUNT. A Participant may
withdraw all of the payroll deductions credited to his or her Plan account and
not previously applied toward the purchase of Stock by delivering to the
Company's designated office a written notice on a form provided by the Company
for such purpose. Amounts withdrawn shall be returned to the Participant as soon
as practicable after the Company's receipt of the notice of withdrawal and may
not be applied to the purchase of shares in any Offering under the Plan. The
Company may from time to time establish or change limitations on the frequency
of withdrawals permitted under this Section, establish a minimum dollar amount
that must be retained in the Participant's Plan account, or terminate the
withdrawal right provided by this Section.

        11. PURCHASE OF SHARES.

            11.1 EXERCISE OF PURCHASE RIGHT. On each Purchase Date of an
Offering Period, each Participant who has not withdrawn from the Plan and whose
participation in the Offering has not otherwise terminated before such Purchase
Date shall automatically acquire pursuant to the exercise of the Participant's
Purchase Right the number of whole shares of Stock determined by dividing (a)
the total amount of the Participant's payroll deductions accumulated in the
Participant's Plan account during the Offering Period and not previously applied
toward the purchase of Stock by (b) the Purchase Price. However, in no event
shall the number of shares purchased by the Participant during an Offering
Period exceed the number of shares subject to the Participant's Purchase Right.
No shares of Stock shall be purchased on a Purchase Date on behalf of a
Participant whose participation in the Offering or the Plan has terminated
before such Purchase Date.

            11.2 PRO RATA ALLOCATION OF SHARES. If the number of shares of Stock
which might be purchased by all Participants in the Plan on a Purchase Date
exceeds the number of shares of Stock available in the Plan as provided in
Section 4.1, the Company shall make a pro rata allocation of the remaining
shares in as uniform a manner as practicable and as the Company determines to be
equitable. Any fractional share resulting from such pro rata allocation to any
Participant shall be disregarded.

            11.3 DELIVERY OF CERTIFICATES. As soon as practicable after each
Purchase Date, the Company shall arrange the delivery to each Participant of a
certificate representing the shares acquired by the Participant on such Purchase
Date; provided that the Company may deliver such shares to a broker designated
by the Company that will hold such shares for the benefit of the Participant.
Shares to be delivered to a Participant under the Plan shall be registered in
the name of the Participant, or, if requested by the Participant, in the name of
the Participant and his or her spouse, or, if applicable, in the names of the
heirs of the Participant.

            11.4 RETURN OF CASH BALANCE. Any cash balance remaining in a
Participant's Plan account following any Purchase Date shall be refunded to the
Participant as soon as practicable after such Purchase Date. However, if the
cash balance to be returned to a Participant pursuant to the preceding sentence
is less than the amount that would have been necessary to purchase an additional
whole share of Stock on such Purchase Date, the Company may retain the cash
balance in the Participant's Plan account to be applied toward the purchase of
shares of Stock in the subsequent Purchase Period or Offering Period, as the
case may be.

                                                                              10
<PAGE>

            11.5 TAX WITHHOLDING. At the time a Participant's Purchase Right is
granted or exercised, in whole or in part, or at the time a Participant disposes
of some or all of the shares of Stock he or she acquires under the Plan, the
Participant shall make adequate provision for the federal, state, local and
foreign income, social insurance and other payroll tax withholding obligations,
if any, of the Participating Company Group which arise upon the grant or
exercise of the Purchase Right or upon such disposition of shares, respectively.
The Participating Company Group may, but shall not be obligated to, withhold
from the Participant's compensation the amount necessary to meet such
withholding obligations.

            11.6 EXPIRATION OF PURCHASE RIGHT. Any portion of a Participant's
Purchase Right remaining unexercised after the end of the Offering Period to
which the Purchase Right relates shall expire immediately upon the end of the
Offering Period.

            11.7 PROVISION OF REPORTS AND STOCKHOLDER INFORMATION TO
PARTICIPANTS. Each Participant who has exercised all or part of his or her
Purchase Right shall receive, as soon as practicable after the Purchase Date, a
report of such Participant's Plan account setting forth the total payroll
deductions accumulated prior to such exercise, the number of shares of Stock
purchased, the Purchase Price for such shares, the date of purchase and the cash
balance, if any, remaining immediately after such purchase that is to be
refunded or retained in the Participant's Plan account pursuant to Section 11.4.
The report required by this Section may be delivered in such form and by such
means, including by electronic transmission, as the Company may determine. In
addition, each Participant shall be provided information concerning the Company
equivalent to that information provided generally to the Company's common
stockholders.

        12. WITHDRAWAL FROM PLAN OR OFFERING.

            12.1 VOLUNTARY WITHDRAWAL FROM THE PLAN. A Participant may withdraw
from the Plan by signing and delivering to the Company's designated office a
written notice of withdrawal on a form provided by the Company for this purpose.
Such withdrawal may be elected at any time prior to the end of an Offering
Period; provided, however, that if a Participant withdraws from the Plan after a
Purchase Date, the withdrawal shall not affect shares of Stock acquired by the
Participant on such Purchase Date. A Participant who voluntarily withdraws from
the Plan is prohibited from resuming participation in the Plan in the same
Offering from which he or she withdrew, but may participate in any subsequent
Offering by again satisfying the requirements of Sections 5 and 7.1. The Company
may impose, from time to time, a requirement that the notice of withdrawal from
the Plan be on file with the Company's designated office for a reasonable period
prior to the effectiveness of the Participant's withdrawal.

            12.2 AUTOMATIC WITHDRAWAL FROM AN OFFERING PERIOD. If the Fair
Market Value of a share of Stock on the first day of an Offering Period is
higher than the Fair Market Value of a share of Stock on the first day of any
subsequent Purchase Period, then every Participant automatically shall be (a)
withdrawn from such Offering after the acquisition of shares of Stock on the
Purchase Date of that Offering Period and (b) enrolled in the new Offering
commencing immediately following such Purchase Date. A Participant may elect not
to be automatically withdrawn from an Offering pursuant to this Section 12.2 by
delivering to the Company's designated

                                                                              11
<PAGE>

office not later than the close of business on the Purchase Date a written
notice indicating such election.

            12.3 RETURN OF PAYROLL DEDUCTIONS. Upon a Participant's voluntary
withdrawal from the Plan pursuant to Section 12.1 or automatic withdrawal from
an Offering pursuant to Section 12.2, the Participant's accumulated payroll
deductions which have not been applied toward the purchase of shares of Stock
(except, in the case of an automatic withdrawal pursuant to Section 12.2, for an
amount necessary to purchase an additional whole share of Stock as provided in
Section 11.4) shall be refunded to the Participant as soon as practicable after
the withdrawal, without the payment of any interest, and the Participant's
interest in the Plan or the Offering, as applicable, shall terminate. Such
accumulated payroll deductions to be refunded in accordance with this Section
may not be applied to any other Offering under the Plan.

        13. TERMINATION OF EMPLOYMENT OR ELIGIBILITY.

            Upon a Participant's ceasing, prior to a Purchase Date, to be an
Employee of the Participating Company Group for any reason, including
retirement, disability or death, or upon the failure of a Participant to remain
an Eligible Employee, the Participant's participation in the Plan shall
terminate immediately. In such event, the Participant's accumulated payroll
deductions which have not been applied toward the purchase of shares shall, as
soon as practicable, be returned to the Participant or, in the case of the
Participant's death, to the Participant's beneficiary designated in accordance
with Section 20, if any, or legal representative, and all of the Participant's
rights under the Plan shall terminate. Interest shall not be paid on sums
returned pursuant to this Section 13 unless required by foreign law for
Participants outside the United States. A Participant whose participation has
been so terminated may again become eligible to participate in the Plan by
satisfying the requirements of Sections 5 and 7.1.

        14. CHANGE IN CONTROL.

            14.1 DEFINITIONS.

                 (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to have
occurred if any of the following occurs with respect to the Company: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the stockholders of the Company of more than fifty percent (50%)
of the voting stock of the Company; (ii) a merger or consolidation in which the
Company is a party; (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or (iv) a liquidation or
dissolution of the Company.

                 (b) A "CHANGE IN CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting securities of the Company or, in the case of a Transaction
described in Section 14.1(a)(iii), the corporation or

                                                                              12
<PAGE>

other business entity to which the assets of the Company were transferred (the
"TRANSFEREE"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting securities of one or more corporations or
other business entities which own the Company or the Transferee, as the case may
be, either directly or through one or more subsidiary corporations or other
business entities. The Board shall have the right to determine whether multiple
sales or exchanges of the voting securities of the Company or multiple Ownership
Change Events are related, and its determination shall be final, binding and
conclusive.

                 14.2 EFFECT OF CHANGE IN CONTROL ON PURCHASE RIGHTS. In the
event of a Change in Control, the surviving, continuing, successor, or
purchasing corporation or other business entity or parent thereof, as the case
may be (the "ACQUIRING CORPORATION"), may, without the consent of any
Participant, assume the Company's rights and obligations under the Plan. If the
Acquiring Corporation elects not to assume the Company's rights and obligations
under the Plan, the Purchase Date of the then current Purchase Period shall be
accelerated to a date before the date of the Change in Control specified by the
Board, but the number of shares of Stock subject to outstanding Purchase Rights
shall not be adjusted. All Purchase Rights which are neither assumed by the
Acquiring Corporation in connection with the Change in Control nor exercised as
of the date of the Change in Control shall terminate and cease to be outstanding
effective as of the date of the Change in Control.

        15. NONTRANSFERABILITY OF PURCHASE RIGHTS.

            Neither payroll deductions credited to a Participant's Plan account
nor a Participant's Purchase Right may be assigned, transferred, pledged or
otherwise disposed of in any manner other than as provided by the Plan or by
will or the laws of descent and distribution. (A beneficiary designation
pursuant to Section 20 shall not be treated as a disposition for this purpose.)
Any such attempted assignment, transfer, pledge or other disposition shall be
without effect, except that the Company may treat such act as an election to
withdraw from the Plan as provided in Section 12.1. A Purchase Right shall be
exercisable during the lifetime of the Participant only by the Participant.

        16. COMPLIANCE WITH SECURITIES LAW.

            The issuance of shares under the Plan shall be subject to compliance
with all applicable requirements of federal, state and foreign law with respect
to such securities. A Purchase Right may not be granted or exercised if the
grant of such Purchase Right or issuance of shares upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any securities exchange
or market system upon which the Stock may then be listed. In addition, no
Purchase Right may be exercised unless (a) a registration statement under the
Securities Act of 1933, as amended, shall at the time of exercise of the
Purchase Right be in effect with respect to the shares issuable upon exercise of
the Purchase Right, or (b) in the opinion of legal counsel to the Company, the
shares issuable upon exercise of the Purchase Right may be issued in accordance
with the terms of an applicable exemption from the registration requirements of
said Act. The inability of the Company to obtain from any regulatory body having
jurisdiction the authority, if any, deemed by the Company's legal counsel to be
necessary to the lawful issuance and sale of any shares under the Plan shall
relieve the Company of

                                                                              13
<PAGE>

any liability in respect of the failure to grant such Purchase Right or sell
such shares as to which such requisite authority shall not have been obtained.
As a condition to the grant or exercise of a Purchase Right, the Company may
require the Participant to satisfy any qualifications that may be necessary or
appropriate, to evidence compliance with any applicable law or regulation, and
to make any representation or warranty with respect thereto as may be requested
by the Company.

        17. RIGHTS AS A STOCKHOLDER AND EMPLOYEE.

            A Participant shall have no rights as a stockholder by virtue of the
Participant's participation in the Plan until the date of the issuance of a
certificate for the shares purchased pursuant to the exercise of the
Participant's Purchase Right (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company). No
adjustment shall be made for dividends, distributions or other rights for which
the record date is prior to the date such certificate is issued, except as
provided in Section 4.2. Nothing herein shall confer upon a Participant any
right to continue in the employ of the Participating Company Group or interfere
in any way with any right of the Participating Company Group to terminate the
Participant's employment at any time.

        18. LEGENDS.

            The Company may at any time place legends or other identifying
symbols referencing any applicable federal, state or foreign securities law
restrictions or any provision convenient in the administration of the Plan on
some or all of the certificates representing shares of Stock issued under the
Plan. The Participant shall, at the request of the Company, promptly present to
the Company any and all certificates representing shares acquired pursuant to a
Purchase Right in the possession of the Participant in order to carry out the
provisions of this Section. Unless otherwise specified by the Company, legends
placed on such certificates may include but shall not be limited to the
following:

"THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE CORPORATION TO THE
REGISTERED HOLDER UPON THE PURCHASE OF SHARES UNDER AN EMPLOYEE STOCK PURCHASE
PLAN AS DEFINED IN SECTION 423 OF THE UNITED STATES INTERNAL REVENUE CODE OF
1986, AS AMENDED. THE TRANSFER AGENT FOR THE SHARES EVIDENCED HEREBY SHALL
NOTIFY THE CORPORATION IMMEDIATELY OF ANY TRANSFER OF THE SHARES BY THE
REGISTERED HOLDER HEREOF. THE REGISTERED HOLDER SHALL HOLD ALL SHARES PURCHASED
UNDER THE PLAN IN THE REGISTERED HOLDER'S NAME (AND NOT IN THE NAME OF ANY
NOMINEE)."

        19. NOTIFICATION OF DISPOSITION OF SHARES.

            The Company may require the Participant to give the Company prompt
notice of any disposition of shares acquired by exercise of a Purchase Right.
The Company may require that until such time as a Participant disposes of shares
acquired upon exercise of a Purchase Right, the Participant shall hold all such
shares in the Participant's name (or, if elected by the Participant, in the name
of the Participant and his or her spouse but not in the name of any nominee)
until the later of

                                                                              14

two years after the date of grant of such Purchase Right or one year after the
date of exercise of such Purchase Right. The Company may direct that the
certificates evidencing shares acquired by exercise of a Purchase Right refer to
such requirement to give prompt notice of disposition.

        20. DESIGNATION OF BENEFICIARY.

            20.1 DESIGNATION PROCEDURE. Unless otherwise restricted by the Board
for participants outside the United States, a Participant may file a written
designation of a beneficiary who is to receive (a) shares and cash, if any, from
the Participant's Plan account if the Participant dies subsequent to a Purchase
Date but prior to delivery to the Participant of such shares and cash or (b)
cash, if any, from the Participant's Plan account if the Participant dies prior
to the exercise of the Participant's Purchase Right. If a married Participant
designates a beneficiary other than the Participant's spouse, the effectiveness
of such designation shall be subject to the consent of the Participant's spouse.
A Participant may change his or her beneficiary designation at any time by
written notice to the Company.

            20.2 ABSENCE OF BENEFICIARY DESIGNATION. If a Participant dies
without an effective designation pursuant to Section 20.1 of a beneficiary who
is living at the time of the Participant's death, the Company shall deliver any
shares or cash credited to the Participant's Plan account to the Participant's
legal representative.

        21. NOTICES.

            All notices or other communications by a Participant to the Company
under or in connection with the Plan shall be deemed to have been duly given
when received in the form specified by the Company at the location, or by the
person, designated by the Company for the receipt thereof.

        22. AMENDMENT OR TERMINATION OF THE PLAN.

            The Board may at any time amend or terminate the Plan, except that
(a) no such amendment or termination shall affect Purchase Rights previously
granted under the Plan unless expressly provided by the Board and (b) no such
amendment or termination may adversely affect a Purchase Right previously
granted under the Plan without the consent of the Participant, except to the
extent permitted by the Plan or as may be necessary to qualify the Plan as an
employee stock purchase plan pursuant to Section 423 of the Code or to comply
with any applicable law, regulation or rule. In addition, an amendment to the
Plan must be approved by the stockholders of the Company within twelve (12)
months of the adoption of such amendment if such amendment would authorize the
sale of more shares than are then authorized for issuance under the Plan or
would change the definition of the corporations that may be designated by the
Board as Participating Companies.

        23. RULES FOR FOREIGN JURISDICTIONS.

                                                                              15

            23.1 SPECIAL RULES OR PROCEDURES. Notwithstanding any provision to
the contrary in this Plan, the Board may adopt rules or procedures relating to
the operation and administration of the Plan to accommodate the specific
requirements of local laws and procedures for jurisdictions outside of the
United States. Without limiting the generality of the foregoing, the Board is
specifically authorized to adopt rules and procedures regarding eligibility to
participate, the definition of Compensation, handling of payroll deductions,
making of contributions to the Plan in forms other than payroll deductions,
establishment of bank or trust accounts to hold payroll deductions, payment of
interest, conversion of local currency, obligations to pay payroll tax,
determination of beneficiary designation requirements, withholding procedures
and handling of stock certificates which vary with local requirements.

            23.2 NON-423 PLAN RULES, PROCEDURES OR SUB-PLANS. The Board may also
adopt rules, procedures or sub-plans applicable to particular Subsidiary
Corporations or locations, which sub-plans may be designed to be outside the
scope of Section 423 of the Code. The rules of such sub-plans may take
precedence over other provisions of this Plan, with the exception of Sections
4.1 and 22, but unless otherwise superseded by the terms of such sub-plan, the
provisions of this Plan shall govern the operation of such sub-plan. To the
extent inconsistent with the requirements of Section 423 of the Code, the
Purchase Rights granted under such sub-plans shall not be considered to comply
with Section 423 of the Code.

                                                                              16
