                             GADZOOX NETWORKS, INC.

              EMPLOYMENT, CHANGE OF CONTROL AND SEVERANCE AGREEMENT

       This Employment, Change of Control and Severance Agreement (the
"Agreement") is made and entered into effective as of September 29, 2000 (the
"Effective Date"), by and between Ronald G. von Trapp (the "Employee") and
Gadzoox Networks, Inc., a Delaware corporation (the "Company").

                                    RECITALS

       A. The Board desires to provide the Employee certain severance benefits
in the event Employee's employment with the Company terminates at any time as a
result of Involuntary Termination other than for Cause.

       B. Additionally, it is expected that the Company from time to time will
consider the possibility of an acquisition by another company or other change of
control. The Board of Directors of the Company (the "Board") recognizes that
such consideration can be a distraction to the Employee and can cause the
Employee to consider alternative employment opportunities.

       C. The Board believes that it is in the best interests of the Company and
its shareholders to provide the Employee with an incentive to continue his
employment and to maximize the value of the Company upon a Change of Control for
the benefit of its shareholders.

       D. The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change of Control and thereby provide the Employee with enhanced
financial security and sufficient encouragement to remain with the Company
notwithstanding the possibility of a Change of Control.

       E. Certain capitalized terms used in the Agreement are defined in Section
10 below.

                                    AGREEMENT

       In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Employee by the Company, the
parties agree as follows:

       1. Duties and Scope of Employment.

              (a) Position. The Company shall employ the Employee in the
position of Vice President, Worldwide Sales, with such duties, responsibilities
and compensation as previously discussed; provided, however, that the Board
shall have the right, prior to the occurrence of a

<PAGE>   2

Change of Control, to revise such responsibilities and compensation from time to
time as the Board may deem necessary or appropriate.

              (b) Obligations. The Employee shall devote his full business
efforts and time to the Company and its subsidiaries. The foregoing, however,
shall not preclude the Employee from engaging in such activities and services as
do not interfere or conflict with his responsibilities to the Company.

       2. At-Will Employment. The Company and the Employee acknowledge that the
Employee's employment is and shall continue to be at-will, as defined under
applicable law. If the Employee's employment terminates for any reason, the
Employee shall not be entitled to any payments, benefits, damages, awards or
compensation other than as provided by this Agreement, or as may otherwise be
available in accordance with the Company's established employee plans and
practices or other agreements with the Company at the time of termination.

       3. Compensation and Benefits.

              (a) Base Compensation. The Company shall pay the Employee as
compensation for services a base salary at the annualized rate of Two Hundred
Thousand Dollars ($200,000). Such salary shall be reviewed at least annually and
may be increased from time to time subject to accomplishment of such performance
and contribution goals and objectives as may be established from time to time by
the Board of Directors. Such salary shall be paid periodically in accordance
with normal Company payroll practices. The annual compensation specified in this
Section 3(a), together with any increases in such compensation that the Board
may grant from time to time, is referred to in this Agreement as "Base
Compensation."

              (b) Bonus. For each fiscal year during the term of this Agreement,
the Employee shall be eligible to receive an annual bonus at the annualized rate
of Two Hundred Thousand Dollars ($200,000) (prorated for the first fiscal year)
based upon targets to be mutually agreed upon by the Employee and the Company
within the Employee's first month of employment (the "Target Bonus"). The Bonus
payable hereunder shall be paid in accordance with the Company's normal
practices and policies.

              (c) Forgivable Loan. The Company shall loan to the Employee the
sum of $250,000, which shall be forgivable over twenty-four (24) months, on the
terms set forth in Exhibit A attached hereto.

              (d) Stock Options. Subject to the approval of the Board of
Directors of the Company, the Employee shall be granted an option to purchase
225,000 shares of Common Stock (the "Option") with an exercise price equal to
the fair market value of the Common Stock as of the date immediately preceding
the date of Board approval. Twenty-five percent (25%) of the shares subject to
the Option shall vest on the first anniversary of Employee's first day of
employment with the Company and 1/48 of the shares subject to the Option shall
vest each month thereafter so long as the Employee continues to be employed by
the Company on such dates.

                                      -2-
<PAGE>   3

              (e) Employee Benefits. The Employee shall be eligible to
participate in the employee benefit plans and executive compensation programs
maintained by the Company applicable to other key executives of the Company,
including (without limitation) retirement plans, savings or profit-sharing
plans, deferred compensation plans, supplemental retirement or excess-benefit
plans, stock option, incentive or other bonus plans, life, disability, health,
accident and other insurance programs, paid vacations, and similar plans or
programs, subject in each case to the generally applicable terms and conditions
of the plan or program in question and to the determination of any committee
administering such plan or program.

       4. Severance Benefits.

              (a) If the Employee's employment with the Company terminates at
any time as a result of Involuntary Termination other than for Cause, the
Employee shall be entitled to receive the following:

                     (i) A continuation of the Employee's Base Compensation in
effect at the time of such termination for a period equal to twelve (12) months,
in accordance with the Company's normal payroll practices;

                     (ii) In addition to any portion of the Employee's stock
options and/or restricted stock that were vested immediately prior to such
termination, such options and/or restricted stock shall become vested and
immediately exercisable as to an additional amount as though the Employee had
remained continuously employed for a period of twelve (12) months following such
termination and

                     (iii) The Employee and each eligible dependent who
constitutes a qualified beneficiary, as defined in Section 4980B(g)(1) of the
Internal Revenue Code of 1986, as amended, will be eligible to continue coverage
under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
("COBRA"), within the time period prescribed pursuant to COBRA. For a period of
twelve months following the Termination Date, the Company agrees to pay for or
reimburse the Employee for any COBRA premiums required to obtain continued
coverage. The Employee agrees, however, that any obligation to provide COBRA
benefits or reimbursement pursuant to this paragraph shall cease upon the date
that the Employee commences full time employment with a third party, provided
said third party has comparable medical benefits.

              (b) In addition, without regard to the reason for termination of
the Employee's employment: (i) the Company shall pay the Employee any unpaid
Base Compensation due for periods prior to the Termination Date; (ii) the
Company shall pay the Employee all of the Employee's accrued and unused vacation
through the Termination Date; and (iii) following submission of proper expense
reports by the Employee, the Company shall reimburse the Employee for all
expenses reasonably and necessarily incurred by the Employee in connection with
the business of the Company prior to termination. These payments shall be made
promptly upon termination and within the period of time mandated by law.

       5. Termination Following A Change of Control. If the Employee's
employment with the Company terminates at any time as a result of Involuntary
Termination other than for Cause within

                                      -3-
<PAGE>   4

twelve (12) months after a Change of Control, then, subject to Section 7 hereof,
the fifty percent (50%) of the unvested portion of any and all stock options and
restricted stock as of the Termination Date shall become vested and immediately
exercisable and any repurchase option applicable to restricted stock shall
terminate so as to become completely vested as to such shares.

       6. Voluntary Resignation; Termination For Cause. For the purposes of
Sections 4 and 5 hereof, if the Employee's employment terminates by reason of
the Employee's voluntary resignation (and is not an Involuntary Termination), or
if the Employee is terminated for Cause, then the Employee shall not be entitled
to receive severance, accelerated vesting or other benefits except for those (if
any) as may then be established under the Company's then existing severance and
benefits plans and policies at the time of such termination.

       7. Disability; Death. For the purposes of Sections 4 and 5 hereof, if the
Company terminates the Employee's employment as a result of the Employee's
Disability, or such Employee's employment is terminated due to the death of the
Employee, then the Employee shall not be entitled to receive severance or other
benefits except for those (if any) as may then be established under the
Company's then existing severance and benefits plans and policies at the time of
such Disability or death.

       8. Limitation on Payments. In the event that the severance and other
benefits provided for in this Agreement or otherwise payable to the Employee (i)
constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code") and (ii) but for this
Section, would be subject to the excise tax imposed by Section 4999 of the Code,
then the Employee's severance benefits under subsection 4(a)(i) shall be payable
either

              (a) in full, or

              (b) as to such lesser amount which would result in no portion of
such severance benefits being subject to excise tax under Section 4999 of the
Code,

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the excise tax imposed by Section 4999, results
in the receipt by the Employee on an after-tax basis, of the greatest amount of
severance benefits under Section 4(a) hereof, notwithstanding that all or some
portion of such severance benefits may be taxable under Section 4999 of the
Code. Unless the Company and the Employee otherwise agree in writing, any
determination required under this Section 8 shall be made in writing by the
Company's independent public accountants (the "Accountants"), whose
determination shall be conclusive and binding upon the Employee and the Company
for all purposes. For purposes of making the calculations required by this
Section 8, the Accountants may make reasonable assumptions and approximations
concerning applicable taxes and may rely on reasonable, good faith
interpretations concerning the application of Sections 280G and 4999 of the
Code. The Company and the Employee shall furnish to the Accountants such
information and documents as the Accountants may reasonably request in order to
make a determination under this Section. The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this Section 8.

                                      -4-

       9. Certain Business Combinations. In the event it is determined by the
Board of Directors, upon receipt of a written opinion of the Corporation's
independent public accountants, that the enforcement of any provision of this
Agreement, including, but not limited to, Section 5 hereof, which allows for the
acceleration of vesting of options to purchase shares of the Company's common
stock upon a termination in connection with a Change of Control, would preclude
accounting for any proposed business combination of the Company involving a
Change of Control as a pooling of interests, and the Board otherwise desires to
approve such a proposed business transaction which requires as a condition to
the closing of such transaction that it be accounted for as a pooling of
interests, then any such provision of this Agreement shall be null and void. For
purposes of this Section 9, the Board's determination shall require the
unanimous approval of the disinterested Board members.

       10. Definition of Terms. The following terms referred to in this
Agreement shall have the following meanings:

              (a) Change of Control. "Change of Control" shall mean the
occurrence of any of the following events:

                     (i) Any "person" (as such term is used in Sections 13(d)
and 14(d) of the Securities Exchange Act of 1934, as amended) becoming the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities,
other than in a private financing where securities are acquired directly from
the Company; or

                     (ii) The merger or consolidation of the Company with any
other corporation, other than a merger or consolidation which would result in
the voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least fifty percent (50%) of
the total voting power represented by the voting securities of the Company or
such surviving entity outstanding immediately after such merger or
consolidation, or the sale or disposition by the Company of all or substantially
all the Company's assets.

              (b) Involuntary Termination. "Involuntary Termination" shall mean
(i) without the Employee's express written consent, a significant reduction of
the Employee's duties, position or responsibilities, or the removal of the
Employee from such position and responsibilities, unless the Employee is
provided with a comparable position (i.e., a position of equal or greater
organizational level, duties, authority, compensation and status); provided
however, that a reduction is title, duties or responsibilities solely by virtue
of the Company being acquired and made part of a larger entity (as, for example,
when the Employee, if Vice President, Worldwide Sale of the Company immediately
prior to a Change of Control, remains as such following a Change of Control and
is not made the Vice President Worldwide Sales of the acquiring corporation or a
division thereof) shall not constitute an "Involuntary Termination"; (ii)
without the Employee's express written consent, a substantial reduction, without
good business reasons, of the facilities and perquisites (including office space
and location) available to the Employee immediately prior to such reduction;
(iii) a significant reduction by the Company in the Base Compensation of the
Employee as in effect immediately prior to such reduction; (iv) a material
reduction by the Company in the kind or level of

                                      -5-
<PAGE>   6

employee benefits to which the Employee is entitled immediately prior to such
reduction with the result that the Employee's overall benefits package is
significantly reduced; (v) without the Employee's express written consent, the
relocation of the Employee to a facility or a location more than 50 miles from
the Employee's then present location; (vi) any purported termination of the
Employee by the Company which is not effected for Disability or for Cause, or
any purported termination for which the grounds relied upon are not valid; or
(vii) the failure of the Company to obtain the assumption of this Agreement by
any successors contemplated in Section 11 below.

              (c) Cause. "Cause" shall mean (i) any act of personal dishonesty
taken by the Employee in connection with his responsibilities as an employee and
intended to result in substantial personal enrichment of the Employee, (ii) the
conviction of a felony which the Board reasonably believes had or will have a
material detrimental effect on the Company's reputation or business, (iii) a
willful act by the Employee which constitutes gross misconduct and which is
injurious to the Company, and (iv) continued violations by the Employee of the
Employee's obligations after there has been delivered to the Employee a written
demand for performance from the Company which describes the basis for the
Company's belief that the Employee has not substantially performed his duties.

              (d) Disability. "Disability" shall mean that the Employee has been
unable to perform his duties under this Agreement as the result of his
incapacity due to physical or mental illness, and such inability, at least 26
weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the Employee
or the Employee's legal representative (such agreement as to acceptability not
to be unreasonably withheld).

              (e) Termination Date. "Termination Date" shall mean the date on
which either party delivers a notice of termination to the other.

       11. Successors.

              (a) Company's Successors. Any successor to the Company (whether
direct or indirect and whether by purchase, lease, merger, consolidation,
liquidation or otherwise) to all or substantially all of the Company's business
and/or assets shall assume the obligations under this Agreement and agree
expressly to perform the obligations under this Agreement in the same manner and
to the same extent as the Company would be required to perform such obligations
in the absence of a succession. For all purposes under this Agreement, the term
"Company" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this
subsection (a) or which becomes bound by the terms of this Agreement by
operation of law.

              (b) Employee's Successors. The terms of this Agreement and all
rights of the Employee hereunder shall inure to the benefit of, and be
enforceable by, the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributes, devisees and legatees.

                                      -6-

       12. Notice.

              (a) General. Notices and all other communications contemplated by
this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid. In the case of the Employee,
mailed notices shall be addressed to him at the home address which he most
recently communicated to the Company in writing. In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its Secretary.

              (b) Notice of Termination. Any termination by the Company for
Cause or by the Employee as a result of a voluntary resignation or an
Involuntary Termination shall be communicated by a notice of termination to the
other party hereto given in accordance with Section 12(a) of this Agreement.
Such notice shall indicate the specific termination provision in this Agreement
relied upon, shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination under the provision so indicated, and
shall specify the termination date (which shall be not more than 30 days after
the giving of such notice). The failure by the Employee to include in the notice
any fact or circumstance which contributes to a showing of Involuntary
Termination shall not waive any right of the Employee hereunder or preclude the
Employee from asserting such fact or circumstance in enforcing his rights
hereunder.

       13. Arbitration. At the option of either party, any and all disputes or
controversies whether of law or fact and of any nature whatsoever arising from
or respecting this Agreement shall be decided by arbitration in accordance with
the rules and regulations of the American Arbitration Association.

              The arbitrator shall be selected as follows: in the event the
Company and the Employee agree on one arbitrator, the arbitration shall be
conducted by such arbitrator. In the event the Company and the Employee do not
so agree, the Company and the Employee shall each select one independent,
qualified arbitrator and the two arbitrators so selected shall select the third
arbitrator. The Company reserves the right to object to any individual
arbitrator who shall be employed by or affiliated with a competing organization.

              Arbitration shall take place at Santa Clara County, California, or
any other location mutually agreeable to the parties. At the request of either
party, arbitration proceedings will be conducted in the utmost secrecy; in such
case all documents, testimony and records shall be received, heard and
maintained by the arbitrators in secrecy under seal, available for the
inspection only of the Company or the Employee and their respective attorneys
and their respective experts who shall agree in advance and in writing to
receive all such information confidentially and to maintain such information in
secrecy until such information shall become generally known. The arbitrator, who
shall act by majority vote, shall be able to decree any and all relief of an
equitable nature, including but not limited to such relief as a temporary
restraining order, a temporary and/or a permanent injunction, and shall also be
able to award damages, with or without an accounting and costs, provided that
punitive damages shall not be awarded. The decree or judgment of an award
rendered by the arbitrators may be entered in any court having jurisdiction
thereof.

                                      -7-
<PAGE>   8

              Reasonable notice of the time and place of arbitration shall be
given to all persons, other than the parties, as shall be required by law, in
which case such persons or those authorized representatives shall have the right
to attend and/or participate in all the arbitration hearings in such manner as
the law shall require.

       14. Miscellaneous Provisions.

              (a) No Duty to Mitigate. The Employee shall not be required to
mitigate the amount of any payment contemplated by this Agreement, nor shall any
such payment be reduced by any earnings that the Employee may receive from any
other source.

              (b) Waiver. No provision of this Agreement shall be modified,
waived or discharged unless the modification, waiver or discharge is agreed to
in writing and signed by the Employee and by an authorized officer of the
Company (other than the Employee). No waiver by either party of any breach of,
or of compliance with, any condition or provision of this Agreement by the other
party shall be considered a waiver of any other condition or provision or of the
same condition or provision at another time.

              (c) Whole Agreement. No agreements, representations or
understandings (whether oral or written and whether express or implied) which
are not expressly set forth in this Agreement have been made or entered into by
either party with respect to the subject matter hereof.

              (d) Choice of Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of
California.

              (e) Severability. The invalidity or unenforceability of any
provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision hereof, which shall remain in full force
and effect.

              (f) No Assignment of Benefits. The rights of any person to
payments or benefits under this Agreement shall not be made subject to option or
assignment, either by voluntary or involuntary assignment or by operation of
law, including (without limitation) bankruptcy, garnishment, attachment or other
creditor's process, and any action in violation of this subsection (f) shall be
void.

              (g) Employment Taxes. All payments made pursuant to this Agreement
will be subject to withholding of applicable income and employment taxes.

              (h) Assignment by Company. The Company may assign its rights under
this Agreement to an affiliate, and an affiliate may assign its rights under
this Agreement to another affiliate of the Company or to the Company; provided,
however, that no assignment shall be made if the net worth of the assignee is
less than the net worth of the Company at the time of assignment. In the case of
any such assignment, the term "Company" when used in a section of this Agreement
shall mean the corporation that actually employs the Employee.

                                      -8-

              (i) Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together will
constitute one and the same instrument.

tenths percent (6.3%) per annum.

       3. Principal and interest shall be due and payable as follows:

has been delivered to the Employee a written demand for performance from the
Company which describes the basis for the Company's belief that the Employee has
not substantially performed his duties.

       4. Notwithstanding the provisions of paragraph 3, and subject to the
conditions set forth below, on each anniversary of the date of this Note (each,
a "Forgiveness Date"), the Company will forgive an amount equal to One Hundred
Twenty-Five Thousand Dollars ($125,000) of the Principal and all accrued
interest on the outstanding Principal balance. Such forgiveness shall be
conditioned on the following:

              A. That Employee is an employee of the Company as of the relevant
Forgiveness Date and has not given notice of resignation or been given notice of
termination for Cause, or;

              B. That Employee is not on Leave of Absence ("LOA") on the
relevant Forgiveness Date and has not been on LOA during the three (3) month
period immediately prior to the relevant Forgiveness Date, provided however that
if Employee is or has been on LOA, the Forgiveness Date and all subsequent
Forgiveness Dates shall be extended by a number of days equal to the period of
the LOA.

       Any portion of the Principal and all accrued interest which is not
forgiven pursuant to this paragraph or paragraph 3 shall be due and payable as
otherwise set forth in this Note.

       5. If an action is instituted for collection of this Note, the prevailing
party is entitled to be reimbursed for court costs and reasonable attorney's
fees incurred by the holder thereof.

       6. This Note may be amended or modified, and provisions hereof may be
waived, only by the written agreement of Borrower and the Company. No delay or
failure by the Company in exercising any right, power or remedy thereunder shall
operate as a waiver of such right, power or remedy, and a waiver of any right,
power or remedy on any one occasion shall not operate as a bar or waiver of any
such right, power or remedy on any other occasion. Without limiting the
generality of thee foregoing, the delay or failure by the Company for any period
of time to enforce collection of any amounts due hereunder shall not be deemed
to be a waiver of any rights of the Company under contract or under law. The
rights of the Company under this Note are in addition to any other rights and
remedies which the Company may have.

       7. This Note may be prepaid without penalty, in whole or in part, at any
time. All amounts payable hereunder shall be payable in lawful money of the
United States of America.

       8. This Note shall be construed and enforced in accordance with, and the
rights of the parties shall be governed by, the laws of the State of California.

       9. If any payment under this Note is not paid when due, then the parties
agree that 1) the Company's damages shall be difficult to estimate, 2) the
unpaid Principal and accrued interest (to the

                                      -2-
<PAGE>   13

extent permitted by law) shall bear interest at the default rate of Twelve
Percent (12%) per annum, or the highest rate allowed by law, whichever is lower,
from said due date until paid, and 3) the parties agree that such liquidated
damages are a reasonable estimate of the damages the Company will incur as a
consequence of Borrower's default.

                                                                   EXHIBIT 10.1

                             GADZOOX NETWORKS, INC.

                           CHANGE OF CONTROL AGREEMENT

        This Change of Control Agreement (the "AGREEMENT") is made and entered
into effective as of October 20, 2000 (the "EFFECTIVE DATE"), by and between
Wayne Rickard (the "EMPLOYEE") and Gadzoox Networks, Inc., a Delaware
corporation (the "COMPANY").

                                 R E C I T A L S

        A. The Board of Directors of the Company (the "BOARD") expects that the
Company may from time to time consider the possibility of an acquisition of the
Company by another company or other change of control of the Company. The Board
recognizes that such considerations can be a distraction to the Employee and can
cause the Employee to consider alternative employment opportunities.

        B. The Board believes that it is in the best interests of the Company
and for the benefit of its shareholders to provide the Employee with an
incentive to continue his employment and to maximize the value of the Company
upon a Change of Control.

        C. Certain capitalized terms used in the Agreement are defined in
SECTION 7 below.

                                    AGREEMENT

        NOW, THEREFORE, in consideration of the mutual covenants herein
contained, and in consideration of the continuing employment of the Employee by
the Company, the parties agree as follows:

        1. EMPLOYMENT.

           (a) Position. The Company has and continues to employ the Employee in
the position of Senior Vice President/Chief Technology Officer with such duties,
responsibilities and compensation as are in effect as of the Effective Date;
provided, however, that this Agreement shall not in any manner restrict the
Company in its employment relationship with the Employee prior to the occurrence
of a Change of Control, including from revising such duties, responsibilities or
compensation from time to time.

           (b) At-Will Employment. The Company and the Employee acknowledge that
the Employee's employment is and shall continue to be at-will, as defined under
applicable law. If the Employee's employment terminates for any reason, this
Agreement shall not entitle the Employee to any payment, benefit, damage, award
or compensation other than as specifically provided by this Agreement.

<PAGE>   2

        2. TERMINATION FOLLOWING A CHANGE OF CONTROL.

           (a) If a Change of Control occurs while the Employee is employed by
the Company, then, subject to SECTION 4 hereof, the number of all stock options
and restricted stock owned beneficially by the Employee which (A) are, in the
case of stock options, unvested and, in the case of restricted stock, subject to
a repurchase option, as of the effective date of the Change of Control, and (B)
would have been either vested or been released from such repurchase option on
the first anniversary of the first day of the month immediately following the
effective date of the Change of Control, assuming only for such purposes that
the Employee continued to be employed by the Company during such period, shall
on the effective date of the Change of Control be fully vested (and immediately
exercisable) and any such repurchase option shall cease to apply to such
restricted stock, regardless of whether or not the Employee's employment with
the Company continues following the effective date of the Change of Control. The
balance of any unvested stock options or restricted stock subject to a
repurchase option not so accelerated shall continue to vest on the same schedule
that existed prior to the Change of Control with respect to such options or
stock.

           (b) If the Employee's employment with the Company terminates at any
time as a result of the Involuntary Termination of the Employee within twelve
(12) months immediately following a Change of Control, then, subject to SECTION
4 hereof, all stock options and restricted stock owned beneficially by the
Employee and which are, in the case of stock options, unvested and, in the case
of restricted stock, subject to a repurchase option as of the effective time of
the Change of Control event shall become vested (and immediately exercisable)
and any such repurchase option shall cease to apply to such restricted stock.

        3. VOLUNTARY RESIGNATION; TERMINATION FOR CAUSE. If the Employee's
employment terminates by reason of the Employee's voluntary resignation (and is
not an Involuntary Termination), or if the Employee is terminated for Cause,
then the Employee shall not be entitled to receive any accelerated vesting (as
may be provided by SECTION 2 hereof) or other benefit from the Company pursuant
to this Agreement.

        4. DISABILITY; DEATH. If the Company terminates the Employee's
employment as a result of the Employee's Disability, or the Employee's
employment with the Company is terminated due to the death of the Employee, then
the Employee shall not be entitled to receive any accelerated vesting (as may be
provided by SECTION 2) or other benefit from the Company.

        5. LIMITATION ON PAYMENTS. If the benefits provided for in this
Agreement to the Employee (i) constitute a "parachute payment(s)" within the
meaning of SECTION 280G of the Internal Revenue Code of 1986, as amended (the
"CODE") and (ii) but for this Section, would be subject to the excise tax
imposed by SECTION 4999 of the Code, then the Employee's severance benefits
under SECTION 2 shall be payable either:

           (a) in full; or

           (b) as to such lesser amount which would result in no portion of such
severance benefits being subject to excise tax under SECTION 4999 of the Code,

                                      -2-
<PAGE>   3

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the excise tax imposed by SECTION 4999, results
in the receipt by the Employee on an after-tax basis, of the greatest amount of
severance benefits under SECTION 4(a) hereof, notwithstanding that all or some
portion of such severance benefits may be taxable under SECTION 4999 of the
Code. Unless the Company and the Employee otherwise agree in writing, any
determination required under this SECTION 5 shall be made in writing by the
Company's independent public accountants (the "Accountants"), whose
determination shall be conclusive and binding upon the Employee and the Company
for all purposes. For purposes of making the calculations required by this
SECTION 5, the Accountants may make reasonable assumptions and approximations
concerning applicable taxes and may rely on reasonable, good faith
interpretations concerning the application of SECTIONS 280G AND 4999 of the
Code. The Company and the Employee shall furnish to the Accountants such
information and documents as the Accountants may reasonably request in order to
make a determination under this Section. The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this SECTION 5.

        6. CERTAIN BUSINESS COMBINATIONS. If the Board determines, upon receipt
of a written opinion of the Corporation's independent public accountants, that
the enforcement of any provision of this Agreement would preclude accounting for
any proposed business combination of the Company involving a Change of Control
as a pooling of interests, and the Board otherwise determines to approve such a
proposed business transaction which requires as a condition to the closing of
such transaction that it be accounted for as a pooling of interests, then any
such provision of this Agreement shall be null and void.

        7. DEFINITIONS. The following terms referred to in this Agreement shall
have the following meanings:

           (a) "CAUSE" means (i) any act of personal dishonesty taken by the
Employee in connection with his responsibilities as an employee of the Company
and intended to result in substantial personal enrichment of the Employee, (ii)
the Employee being convicted of a felony, (iii) a willful act by the Employee
which constitutes gross misconduct and which is injurious to the Company, and
(iv) the repeated failure by the Employee to perform the Employee's assigned
duties or responsibilities as an employee of the Company after there has been
delivered to the Employee a written demand for performance from the Company
which describes the basis for the Company's belief that the Employee has not
substantially performed his duties or responsibilities.

           (b) "CHANGE OF CONTROL" means the occurrence of any of the following:
(A) When any "person," as such term is used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), other than the
Company, a subsidiary of the Company or a Company employee benefit plan,
including any trustee of such plan acting as trustee, is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing fifty percent (50%) or
more of the combined voting power of the Company's then outstanding securities
entitled to vote generally in the election of directors; provided, however, that
sales by the Company of its equity securities shall not constitute a Change of
Control; or (B) the effective date of a merger or consolidation of the Company
with any other third party, other than a merger or consolidation which would
result in the voting securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining

                                      -3-
<PAGE>   4

outstanding or by being converted into voting securities of the surviving entity
or the entity that controls such surviving entity) at least fifty percent (50%)
of the total voting power represented by the voting securities of the Company,
such surviving entity or the entity that controls such surviving entity
outstanding immediately after such merger or consolidation, or the stockholders
of the Company approve an agreement for the sale or disposition by the Company
of all or substantially all the Company's assets.

           (c) "DISABILITY" means that the Employee, at the time notice has been
given, has been unable to perform his assigned duties or responsibilities as an
employee of the Company for a period of 26 consecutive weeks as the result of
his incapacity due to physical or mental illness. If the Employee resumes the
performance of substantially all of his assigned duties or responsibilities
before the termination of his employment for the purposes of this Agreement
becomes effective, the notice of termination shall automatically be deemed to
have been revoked. This Agreement shall not confer any benefit to the Employee
and no compensation or benefits will be paid or provided to the Employee under
this Agreement on account of termination for Disability, or for periods
following the date when such a termination of employment is effective. The
Employee's rights under the benefit plans of the Company shall be determined
under the provisions of those plans.

           (d) "INVOLUNTARY TERMINATION" means any of the following not
undertaken for Cause (i) without the Employee's express written consent, a
significant reduction of the Employee's duties, position or responsibilities, or
the removal of the Employee from such position and responsibilities, unless the
Employee is provided with a comparable position (i.e., a position of equal or
greater organizational level, duties, authority, compensation and status);
provided however, that (A) a reduction in duties, position or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Employee, if Chief Executive Officer of the Company
immediately prior to a Change of Control, remains as such following a Change of
Control and is not made the Chief Executive Officer of the acquiring corporation
or a division thereof) shall not constitute an "Involuntary Termination" and (B)
a reduction by an affirmative act of the Company causing than half of the number
of staff reporting to the Employee shall constitute an "Involuntary
Termination"; (ii) without the Employee's express written consent, a substantial
reduction, without a good business reason, of the facilities and perquisites
(including office space and location) available to the Employee immediately
prior to such reduction; (iii) a significant reduction by the Company in the
Base Compensation of the Employee as in effect immediately prior to such
reduction; (iv) a material reduction by the Company in the kind or level of
employee benefits to which the Employee is entitled immediately prior to such
reduction with the result that the Employee's overall benefits package is
significantly reduced; (v) without the Employee's express written consent, the
relocation of the Employee to a facility or a location more than 50 miles from
the Employee's then present location; and (vi) any purported termination of the
Employee by the Company which is not effected for Disability or for Cause, or
any purported termination for which the grounds relied upon are not valid.

           (e) "TERMINATION DATE" means the date on which either party delivers
to the other a notice of termination of the Employee's employment with the
Company.

        8. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and

                                      -4-
<PAGE>   5

assigns of the Company. This Agreement shall be binding upon the Employee and
his heirs, executors, administrators and assigns.

        9. NOTICE.

           (a) General. Notices and all other communications contemplated by
this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid. In the case of the Employee,
mailed notices shall be addressed to him at the home address which he most
recently communicated to the Company in writing. In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its Secretary.

           (b) Notice of Termination. Any termination by the Company for Cause
or by the Employee as a result of a voluntary resignation or an Involuntary
Termination of the Employee shall be communicated by a notice of termination to
the other party hereto given in accordance with this SECTION. Such notice shall
indicate the specific termination provision in this Agreement relied upon, shall
set forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination under the provision so indicated, and shall specify the
termination date (which shall be not more than 30 days after the giving of such
notice). The failure by the Employee to include in the notice any fact or
circumstance which contributes to a showing of Involuntary Termination of the
Employee shall not waive any right of the Employee hereunder or preclude the
Employee from asserting such fact or circumstance in enforcing his rights
hereunder.

        10. ARBITRATION. Any and all disputes or controversies whether of law or
fact and of any nature whatsoever arising from or respecting this Agreement
shall be finally decided by arbitration in accordance with the rules and
regulations of the American Arbitration Association.

        The arbitrator shall be selected as follows: in the event the Company
and the Employee agree on one arbitrator, the arbitration shall be conducted by
such arbitrator. In the event the Company and the Employee do not so agree, the
Company and the Employee shall each select one independent, qualified arbitrator
and the two arbitrators so selected shall select the third arbitrator. The
Company reserves the right to object to any individual arbitrator who shall be
employed by or affiliated with a competing organization.

        Arbitration shall take place at Santa Clara County, California, or any
other location mutually agreeable to the parties. At the request of either
party, arbitration proceedings will be conducted in the utmost secrecy; in such
case all documents, testimony and records shall be received, heard and
maintained by the arbitrators in secrecy under seal, available for the
inspection only of the Company or the Employee and their respective attorneys
and their respective experts who shall agree in advance and in writing to
receive all such information confidentially and to maintain such information in
secrecy until such information shall become generally known. The arbitrator, who
shall act by majority vote, shall be able to decree any and all relief of an
equitable nature, including but not limited to such relief as a temporary
restraining order, a temporary and/or a permanent injunction, and shall also be
able to award damages, with or without an accounting and

                                      -5-
<PAGE>   6

costs, provided that punitive damages shall not be awarded. The decree or
judgment of an award rendered by the arbitrators may be entered in any court
having jurisdiction thereof.

        Reasonable notice of the time and place of arbitration shall be given to
all persons, other than the parties, as shall be required by law, in which case
such persons or those authorized representatives shall have the right to attend
and/or participate in all the arbitration hearings in such manner as the law
shall require.

        11. MISCELLANEOUS PROVISIONS.

           (a) Waiver. No provision of this Agreement shall be modified, waived
or discharged unless the modification, waiver or discharge is agreed to in
writing and signed by the Employee and by an authorized officer of the Company
(other than the Employee). No waiver by either party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party
shall be considered a waiver of any other condition or provision or of the same
condition or provision at another time.

           (b) Entire Agreement. No agreements, representations or
understandings (whether oral or written and whether express or implied) which
are not expressly set forth in this Agreement have been made or entered into by
either party with respect to the subject matter hereof.

           (c) Governing Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of
California.

           (d) Severability. The invalidity or unenforceability of any provision
or provisions of this Agreement shall not affect the validity or enforceability
of any other provision hereof, which shall remain in full force and effect.

           (e) No Assignment of Benefits. The rights of any person to any
benefit under this Agreement shall not be made subject to option or assignment,
either by voluntary or involuntary assignment or by operation of law, including
(without limitation) bankruptcy, garnishment, attachment or other creditor's
process, and any action in violation of this SECTION (e) shall be void.

           (f) Taxes. All payments made pursuant to this Agreement will be
subject to withholding of applicable income and employment taxes.

           (g) Assignment by Company. The Company may assign its rights under
this Agreement to an affiliate, and an affiliate may assign its rights under
this Agreement to another affiliate of the Company or to the Company. In the
case of any such assignment, the term "Company" when used in a section of this
Agreement shall mean the corporation that actually employs the Employee.

           (h) Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together will
constitute one and the same instrument.

                                      -6-

        IN WITNESS WHEREOF, each of the parties has executed this Agreement, in
the case of the Company by its duly authorized officer, as of the day and year
first above written.
