W I T N E S S E T H:

     WHEREAS, on or about October 9, 2001, Company and Executive entered an
Employment Agreement (the “Agreement”); and

     WHEREAS, the parties desire to amend the Agreement in certain respects.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

     1. Definitions. Unless otherwise provided herein, capitalized terms used
herein shall have the same meaning as provided in the Agreement.

     2. Modifications. The parties hereby amend the Original Agreement as
follows:

(a) Section 6, Compensation, is amended as follows:

(i) Section 6(b) is amended to read in its entirety as follows:

Bonuses. Executive shall be eligible to earn a target bonus (the “Target Bonus”)
according to the terms and conditions of the executive incentive bonus program
(as the same may be amended by the Board of Directors of the Company from time
to time) with respect to a Target Bonus measuring period. The phrase “Target
Bonus measuring period” shall mean three months if the executive incentive bonus
program provides for quarterly bonuses for Executive and twelve months if the
executive incentive bonus program provides for annual bonuses or a combination

(ii) Section 6(c)(i) is amended to read in its entirety as follows:

Termination For Any Reason. Notwithstanding Executive’s entitlement to severance
benefits under certain circumstances discussed below in this Section 6(c), upon

Executive all Base Salary and accrued but unpaid vacation earned through the
date of termination, reimburse Executive for all necessary and reasonable
expenses in accordance with Section 4 and continue Executive’s benefits under
the Company’s then-existing benefit plans and policies for so long as required
by applicable law. In addition, the Company shall also pay Executive a portion
of the Target Bonus derived by multiplying Executive’s Base Salary by the
then-current Target Bonus percentage (60% for 2005, payable annually) and
multiplying the result by the quotient of (A) the number of days in the Target
Bonus measuring period through the date of termination, divided by (B) the
number of days in the Target Bonus measuring period. At the Company’s sole
election and if allowed by law, in lieu of providing benefits under the
Company’s then-existing benefit plans and policies for so long as required, the
Company may pay Executive within thirty (30) days of Executive’s termination of
employment with the Company a cash lump sum equal to the pre-tax cost to the
Company of providing such benefits.

(iii) Section 6(c)(ii) is amended to read in its entirety as follows:

Disability, (C) Executive resigns his/her employment with the Company for Good
Reason, or (D) Executive’s employment with the Company is terminated by the
Company other than for Cause, then, subject to Executive executing, and not
revoking, the Release of Claims attached hereto as Exhibit A with the Company
and complying with Section 13 of this Agreement, (1) Executive shall receive
payments equal to the sum of (A) Executive’s Base Salary for twelve months and
(B) in addition to any portion of a Target Bonus paid pursuant to Section
6(c)(i), either (i) if Executive’s Target Bonus measuring period is quarterly,
the Target Bonus for four quarters, or (ii) if Executive’s Target Bonus
measuring period is annual, or a combination of quarterly and annual,
Executive’s Target Bonus for twelve months; less applicable withholding, and
otherwise in accordance with Section 6(c)(v), (2) the Company shall pay
Executive cash equal to the pre-tax cost to the

Company of providing the portion of the group health, dental and vision plan
continuation coverage premiums for Executive and his/her covered dependents

(“COBRA”), that would have been paid by the Company were he/she still employed
by the Company for twelve (12) months from the date of Executive’s termination
of employment, and (3) all of Executive’s remaining unvested stock options and
shares of restricted stock shall vest immediately, and, if applicable, the
Company’s right to repurchase all of the same such shares immediately shall
lapse.

(iv) Section 6(c)(iv)(2)(A) is amended to read in its entirety as follows:

the acquisition by any individual, entity, or group (within the meaning of
Section 13(d)(3) or 14(d)(2) of the Exchange Act), other than by the Company or
any Affiliate thereof immediately prior to such acquisition, of beneficial
ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
of 50% or more of the combined voting power or economic interests of the then
outstanding voting securities of the Company entitled to vote generally in the
election of directors;

(v) A new Section 6(c)(v) is hereby added to the Agreement, which new Section
shall read in its entirety as follows:

Payments; Target Bonus. All payments due under Section 6(c)(ii) shall be paid as
follows: (1) one-twelfth of the total amount due under Section 6(c)(ii) shall be
payable on the last calendar day of the month in which Executive’s employment
with the Company terminated, and (2) a like amount shall be payable on the last
calendar day of each month thereafter until such amount is paid in full;
provided, however, that if any payments due under Section 6(c)(ii) have not been
paid by March 1 of the calendar year following the calendar year in which
Executive’s employment with the Company terminated, then the remaining amounts
due under Section 6(c)(ii) shall be immediately due and payable on that date.
For purposes of the Target Bonus calculation under this Section 6(c) regarding
Target Bonus measuring periods ending subsequent to the termination of
Executive’s employment,

the Target Bonus shall be deemed to be the same as for the Target Bonus
measuring period during which Executive’s employment terminated, and the goals
shall be deemed to be fully met.

(vi) Section 6(d) is amended to read in its entirety as follows:

Acceleration of Vesting of Option Upon a Change in Control. If Executive is
employed by the Company on the date of a Change in Control, or if Executive is
terminated without Cause prior to a Change in Control during the pendency of a
merger agreement or tender offer which would result in a Change in Control,
then, in addition to any other compensation and benefits provided under this
Agreement, all of Executive’s remaining unvested stock options and shares of
restricted stock shall vest immediately, and, if applicable, the Company’s right
to repurchase the same such shares immediately shall lapse.

(vii) A new Section 6(f) is hereby added to the Agreement, which new Section
shall read in its entirety as follows:

409A Applicability. It is not the parties’ intention for any payment under this
Agreement to create or constitute a “nonqualified deferred compensation plan”
within the meaning of Section 409A of the Internal Revenue Code of 1986, as
amended (a “Deferred Compensation Plan”) In the event that this Agreement or any
compensation payable under this Agreement (the “Payment”) is determined to be a
Deferred Compensation Plan causing Executive to owe any additional federal
income tax, the Company agrees to pay to Executive an additional sum (the “Gross
Up”) in an amount such that the net amount retained by Executive after receiving
both the Payment and the Gross Up and after paying: (i) any additional federal
income tax on the Payment and the Gross Up, and (ii) any federal, state, and
local income taxes on the Gross Up, is equal to the amount of the Payment.
Notwithstanding the above, in the event payment of the Gross Up is or becomes
the sole reason for this Agreement to be a Deferred Compensation Plan, the
preceding sentence shall be void and no Gross Up shall be paid.

     (b) Recognizing the modifications to the business of the Company since the
Agreement was entered, the phrase “network management software” is

sentence is amended such that Section 13(a) reads in its entirety as follows:

Covenant Not to Compete. Upon Executive’s resignation for any reason after a
Change in Control has occurred or termination by the Company for any reason
after a Change in Control has occurred, Executive agrees that until the end of
the twelve (12) month period following the date of the termination of his/her
employment, Executive will not directly engage in (whether as an employee,
consultant, proprietor, shareholder, owner, partner, director or otherwise), or
have any ownership interest in, or participate in the financing, operation,
management, or control of, any Subject Entity that is engaged in the design,
development, marketing, distribution, or sale of anti-virus network security
software or hardware anywhere in the world. For purposes of this Section 13, the
term “Subject Entity” means any entity engaged in the design, development,
marketing, distribution, or sale of anti-virus or network security software or
hardware, including but not limited to the following entities: Cisco Systems
(security business unit only), Computer Associates, Microsoft Corporation,
Dr. Ahn’s, Fortinet, Fsecure, Internet Security Systems, Intrusion Inc., Juniper
Networks, Inc., Panda, RSA, Secure Computing, Sophos, Sourcefire, Symantec, 3Com
(including, but not limited to, its TippingPoint division), and Trend Micro or
any successor of any of the foregoing. Executive understands and agrees that the
Company may delete from, add to or otherwise amend the entities included in the
preceding sentence as Subject Entities from time to time, and the company will
provide written notice to Executive of any such deletion, addition or amendment.
Notwithstanding the foregoing provisions to the contrary, nothing in this
Section 13(a) shall prevent Executive from being employed by, or providing
services to, any division or business unit of any Subject Entity if that
division or business unit is not involved in the design, development, marketing,
distribution, or sale of anti-virus network security software or hardware, as
long as Executive has no responsibilities or duties for any division or business
unit of such Subject Entity that is involved in the design, development,
marketing, distribution or sale of anti-virus network security software or
hardware. Ownership of less than 3% of the outstanding voting stock of a Subject
Entity shall not constitute a violation of this Section 13(a).

     (c) A new Section 8 is hereby added to Exhibit A of the Agreement, which
new Section shall read in its entirety as follows:

This Release does not extend to and shall not relieve the Company from any
