                         SEVERANCE PAY PLAN FOR OFFICERS

     1.  Introduction. The purpose of this Deltagen, Inc. Change of Control
Severance Pay Plan For Officers (the "Plan") is to provide Severance Benefits to
Covered Executives whose employment is terminated in an Eligible Termination.
This document constitutes both the written instrument under which the Plan is
maintained and the Plan's summary plan description.

     2.  Important Terms. To help you understand how this Plan works, it is
important to know the following terms:

         2.1 "Administrator" means the Company, or any person or committee to
whom the Company has delegated any authority or responsibility pursuant to
Section 7, but only to the extent of such delegation.

         2.2 "Cause" means:

         (a) any intentional action or intentional failure to act by the Covered
     Executive which was performed in bad faith and to the material detriment of
     the Company;

         (b) the willful and habitual neglect of the Covered Executive's duties
     of employment; or

         (c) the conviction of a Covered Executive of a felony crime involving
     moral turpitude,

provided that in the event that any of the foregoing events is capable of being

describing the nature of such event and Executive shall thereafter have five (5)
business days to cure such event.

         2.3 "Change of Control" means the occurrence of either of the following
events:

         (a) A change in the composition of the board of directors of the
     Company (the "Board"), as a result of which fewer than one-half of the
     incumbent directors are directors who either:

             (i)  Had been directors of the Company twenty-four (24) months
         prior to such change; or

             (ii) Were elected, or nominated for election, to the Board with the

         14(d) of the Securities Exchange Act of 1934, as amended) who by the
         acquisition or aggregation of securities, is or becomes the beneficial
         owner, 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 ordinarily (and apart from
         rights accruing under special circumstances) having the right to vote
         at elections of directors (the "Base Capital Stock"); except that any
         change in the relative beneficial ownership of the Company's securities
         by any person resulting solely from a reduction in the aggregate number
         of outstanding shares of Base Capital Stock, and any decrease
         thereafter in such person's ownership of securities, shall be
         disregarded until such person increases in any manner, directly or
         indirectly, such person's beneficial ownership of any securities of the
         Company. For purposes of this Subsection (b), the term "person" shall
         not include an employee benefit plan maintained by the Company.

Notwithstanding the foregoing, the term "Change of Control" shall not include a
transaction, the sole purpose of which is to change the state of the Company's
incorporation.

                  2.4  "Company" means Deltagen, Inc., a Delaware corporation
and any successor by merger, acquisition, consolidation or otherwise that

disability or death) of a Covered Executive's employment (a) by the Company for

of 1974, as amended.

                  2.9  "Good Reason" means the Company has, without the written
consent of the Covered Executive:

                  (a)  Reduced the powers, duties or title of the Covered
         Executive;

                  (b)  Reduced the Covered Executive's base salary; or

                  (c)  Required the Covered Executive to relocate his or her
         principal place of business by more than 40 miles from its location

                                        2

<PAGE>

                  2.11 "Plan" means the Deltagen, Inc. Change of Control
Severance Pay Plan For Officers, as set forth in this document, and as hereafter
amended from time to time.

                  2.12 "Severance Benefit" means the benefits the Covered
Executive will be provided pursuant to Section 4 and Appendix A.

         3.       Eligibility. An individual shall become a participant in the
Plan only if he or she receives a Notice of Eligibility. Such a Covered
Executive shall be eligible for a Severance Benefit under the Plan, only if he
or she is also a Covered Executive on his or her Eligible Termination Date.

         4.       Payment of Severance Benefit.

                  4.1  Severance Benefit. A Covered Executive who is eligible to
receive a Severance Benefit under and subject to the terms of Section 3 will
receive such benefit in the amount determined in accordance with Appendix A.

                  4.2  Release. As a condition to receiving any Severance
Benefit under this Plan, each Covered Executive will be required to sign a
waiver and general release of all claims arising out of his or her Eligible
Termination and employment with the Company and its subsidiaries and affiliates,
in a form satisfactory to the Legal Department of the Company.

         5.       Withholding. All federal, state, local and other taxes and any
other required payroll deductions will be withheld from any Severance Benefit.

         6.       Administration. The Company is the Administrator of the Plan
(within the meaning of section 3(16)(A) of ERISA) and has the power to
administer and interpret the Plan in its sole discretion. The Administrator is
the "named fiduciary" of the Plan for purposes of ERISA and will be subject to
the fiduciary standards of ERISA when acting in such capacity. Any decision made
or other action taken by the Administrator with respect to the Plan, and any
interpretation by the Administrator of any term or condition of the Plan, or any
related document, will be conclusive and binding on all persons and be given the
maximum possible deference allowed by law. The Administrator may delegate in
writing to any other person all or any portion of his or her authority or
responsibility with respect to the Plan.

         7.       Amendment or Termination. The Company reserves the right, by
written action to amend, modify or terminate the Plan at any time, without
advance notice to any Covered Executive. Any action of the Company in amending
or terminating the Plan will be taken in a non-fiduciary capacity.
Notwithstanding the foregoing, however, within the period commencing six (6)
months prior to a Change of Control and ending eighteen (18) months after such
Change of Control, no amendment or termination of the Plan shall be effective
without the written consent of an affected Covered Executive if the affect of
the amendment or termination would result in the reduction of the benefits the
Covered Executive would have received had the Plan's provisions in effect
immediately prior to such amendment or termination been applied to the Covered
Executive.

         8.       Claims Procedure. Any employee or other person who believes he
or she is entitled to any payment under the Plan may submit a claim in writing
to the Administrator. If the

                                       3

<PAGE>

claim is denied (in full or in part), the claimant will be provided a written
notice explaining the specific reasons for the denial and referring to the
provisions of the Plan on which the denial is based. The notice will describe
any additional information needed to support the claim, describe the Plan's
appeal procedure, and will also inform the claimant of his or her right to file
a civil lawsuit under section 502(a) of ERISA if the claimant's appeal is
denied. The denial notice will be provided within 90 days after the claim is
received. If special circumstances require an extension of time (up to 90 days),
written notice of the extension will be given within the initial 90-day period.

         9.       Appeal Procedure. If the claimant's claim is denied, the
claimant (or his or her authorized representative) may apply in writing to the
Administrator for a review within 60 days after the claimant received the
decision denying the claim. The claimant (or representative) then has the right
to review, and receive at no charge copies of documents, records, and other
information relevant to the claimant's claim for benefits, and to submit issues
and comments in writing. The Administrator will provide written notice of his or
her decision on review within 60 days after it receives a review request. If
additional time (up to 60 days) is needed to review the request, the claimant
(or representative) will be given written notice of the reason for the delay. If
the appeal is denied (in full or part), the claimant will be provided a written
notice explaining the specific reasons for the denial and referring to the
provisions of the Plan on which the denial is based. The notice will inform the
claimant of his or her right to review, and receive at no charge copies of
documents, records and other information relevant to claimant's claim for
benefits, and will also inform the claimant of his or her right to file a civil
lawsuit under section 502(a) of ERISA.

         10.      Source of Payments. All Severance Benefits will be paid in
cash from the general funds of the Employer; no separate fund will be
established under the Plan; and the Plan will have no assets. Because the Plan
has no assets, there are no assets to be allocated in the event of a Plan
termination. No right of any person to receive any payment under the Plan will
be any greater than the right of any other general unsecured creditor.

         11.      Inalienability. In no event may any current or former employee
of the Company or any of its subsidiaries or affiliates sell, transfer,
anticipate, assign or otherwise dispose of any right or interest under the Plan.
At no time will any such right or interest be subject to the claims of creditors
nor liable to attachment, execution or other legal process.

         12.      No Enlargement of Employment Rights. Neither the establishment
or maintenance of the Plan, any amendment of the Plan, nor the making of any
benefit payment hereunder, will be construed to confer upon any individual any
right to be continued as an employee of the Company. The Company expressly
reserves the right to discharge any of its employees at any time, with or
without cause.

         13.      Applicable Law. The provisions of the Plan will be construed,
administered and enforced in accordance with ERISA and, to the extent
applicable, the laws of the State of California.

                                       4

<PAGE>

     14. Severability. If any provision of the Plan is held invalid or
unenforceable, its invalidity or unenforceability will not affect any other
provision of the Plan, and the Plan will be construed and enforced as if such
provision had not been included.

     15. Headings. Headings in this Plan document are for purposes of reference
only and will not limit or otherwise affect the meaning hereof.

     16. Indemnification. The Company hereby agrees to indemnify and hold
harmless the officers and employees of the Company, and the members of its board
of directors, from all losses, claims, costs or other liabilities arising from
their acts or omissions in connection with the administration, amendment or
termination of the Plan, to the maximum extent permitted by applicable law. This
indemnity will cover all such liabilities, including judgments, settlements and
costs of defense. The Company will provide this indemnity from its own funds to
the extent that insurance does not cover such liabilities.

     18. Statement of ERISA Rights.

         As a Covered Executive under the Plan, you have certain rights and
protections under ERISA:

               (a) You may examine (without charge) all Plan documents,
including any amendments and copies of all documents filed with the U.S.
Department of Labor, such as

                                        5

<PAGE>

the Plan's annual report (IRS Form 5500). These documents are available for your
review in the Company's Human Resources Department.

                    (b) You may obtain copies of all Plan documents and other
Plan information upon written request to the Plan Administrator. A reasonable
charge may be made for such copies.

               In addition to creating rights for Covered Executives, ERISA
imposes duties upon the people who are responsible for the operation of the
Plan. The people who operate the Plan (called "fiduciaries") have a duty to do
so prudently and in the interests of you and the other Covered Executives. No
one, including the Company or any other person, may fire you or otherwise
discriminate against you in any way to prevent you from obtaining a benefit
under the Plan or exercising your rights under ERISA. If your claim for a
severance benefit is denied, in whole or in part, you must receive a written
explanation of the reason for the denial. You have the right to have the denial
of your claim reviewed. (The claim review procedure is explained in Sections 8
and 9 above.)

               Under ERISA, there are steps you can take to enforce the above
rights. For instance, if you request materials and do not receive them within 30
days, you may file suit in a federal court. In such a case, the court may
require the Plan Administrator to provide the materials and to pay you up to
$110 a day until you receive the materials, unless the materials were not sent
because of reasons beyond the control of the Plan Administrator. If you have a
claim which is denied or ignored, in whole or in part, you may file suit in a
state or federal court. If it should happen that you are discriminated against
for asserting your rights, you may seek assistance from the U.S. Department of
Labor, or you may file suit in a federal court.

               In any case, the court will decide who will pay court costs and
legal fees. If you are successful, the court may order the person you have sued
to pay these costs and fees. If you lose, the court may order you to pay these
costs and fees, for example, if it finds that your claim is frivolous.

               If you have any questions regarding the Plan, please consult the
Company's Human Resources Department. If you have any questions about this
statement or about your rights under ERISA, you may contact the nearest area
office of the Pension and Welfare Benefits Administration, U.S. Department of
Labor listed in your telephone directory, or the Division of Technical
Assistance and Inquiries, Pension and Welfare Benefits Administration, U.S.
Department of Labor, 200 Constitution Avenue, NW, Washington, DC 20210. You may
also obtain certain publications about your rights and responsibilities under
ERISA by calling the publications hotline of the Pension and Welfare Benefits
Administration.

     19.  Execution.

          In Witness Whereof, the Company, by its duly authorized officer, has
executed this Plan on the date indicated below.

                                    DELTAGEN, INC.

                                    By _________________________________________

                                    Title ______________________________________

                                    Date _______________________________________

<PAGE>

                                   APPENDIX A

If a Covered Executive is entitled to a Severance Benefit under the Plan, the
amount shall be determined in accordance with this Appendix A.

     1.   Base Pay. The Employer will make a payment equal to six (6) months of
the Covered Executive's regular base pay in effect on his or her Eligible
Termination Date, payable in a lump sum payment within seven (7) days after the
effective date of the Covered Executive executing the general release described
in Section 4.2 of the Plan. The amount payable pursuant to this Section 1 shall
be reduced (but not below $0) by any amount which is determined based on a
Covered Executive's base pay and which is payable as severance under any other
plan, agreement, arrangement or other program (including, but not limited to any
written employment agreement).

     2.   Bonus Payments. The Employer will make a payment equal to the pro-rata
portion of any bonus that would have been earned for the year in which the
Covered Executive's Eligible Termination occurs. This amount shall be determined
by multiplying the amount the bonus would otherwise have equaled (determined by
the Board of Directors based on economic and performance duties through the
effective date of the Eligible Termination by a fraction, the numerator of which
is the portion of the year preceding the Eligible Termination and the
denominator of which is one (1). The amount payable pursuant to this Section 2
of Appendix A shall be reduced (but not below $0) by any amount which is
determined based on a Covered Executive's bonus amounts and which is payable as
severance under any other plan, agreement, arrangement or other program
(including, but not limited to any written employment agreement).

     3.   COBRA Premiums. The Employer will reimburse the COBRA premiums on a
Covered Executive's health care coverage in effect on his or her Eligible
Termination Date for a period equal to the number of months of severance pay
which is payable pursuant to Section 1 of this Appendix A. This period of time
shall be reduced (but not below $0) by any period for which COBRA premiums are
reimbursed under any other plan, agreement, arrangement or other program
(including, but not limited to any written employment agreement).
Notwithstanding the preceding, no COBRA premium shall be reimbursed until the
effective date of the general release described in Section 4.2 of the Plan.

     4.   Loan Forgiveness. Any amount that remains unpaid on any relocation
loan entered into between the Covered Executive and the Employer or Company
shall be forgiven; provided the loan is not otherwise in default on the Covered
Employee's Eligible Termination Date. This loan forgiveness shall be effective
on (and subject to) the effective date of the general release described in
Section 4.2 of the Plan and shall also be subject to the Covered Executive's
payment of any payroll or withholding taxes due with respect to such
forgiveness.<PAGE>

                                                                   EXHIBIT 10.48
                                                                  EXECUTION COPY

                        INTEGRATED TELECOM EXPRESS, INC.

            JAMES G. REGEL AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         This Amended and Restated Employment Agreement (the "Agreement") is
entered into as of May 16, 2002, (the "Effective Date") by and between
Integrated Telecom Express, Inc. (the "Company"), and James G. Regel
("Executive"), and replaces and supercedes in its entirety the Agreement entered
into between the Company and Executive on September 24, 2001 (the "Old
Employment Agreement").

                                    RECITALS

         A.   The Company's Board of Directors (the "Board") has adopted and
announced a plan to wind up and liquidate the Company (the "Liquidation"),
pursuant to which the Company will discontinue all of its operations and,
subject to stockholder approval, distribute the assets of the Company to the
Company's stockholders.

         B.   The Board and Executive now desire to amend the Old Employment
Agreement to provide appropriate compensation and incentive to Executive in
light of the Liquidation.

         1.   Duties and Scope of Employment.

              (a) Positions and Duties. As of the Effective Date, Executive will
continue to serve as Chief Executive Officer of the Company. Executive will
render such business and professional services in the performance of his duties,
consistent with Executive's position within the Company, as shall reasonably be
assigned to him by the Board, including managing and overseeing the Liquidation.
The period of Executive's employment under this Agreement is referred to herein
as the "Employment Term."

              (b) Obligations. During the Employment Term, Executive will
perform his duties faithfully and to the best of his ability and will devote his
full business efforts, time and energies to the Company. For the duration of the
Employment Term, Executive agrees not to actively engage in any other
employment, occupation or consulting activity for any direct or indirect
remuneration without the prior approval of the Board, which approval shall not
be unreasonably withheld or delayed, provided however that this Section 1(b)
shall not restrict or prohibit Executive from searching for or interviewing for
other positions so long as those activities do not interfere with the discharge
of his duties to the Company.

         2.   At-Will Employment. The parties agree that Executive's employment
with the Company will be "at-will" employment and may be terminated at any time
with or without cause or notice. Executive understands and agrees that neither
his job performance nor promotions, commendations, bonuses or the like from the
Company give rise to or in any way serve as the basis for modification,
amendment, or extension, by implication or otherwise, of his employment with the
Company.

<PAGE>

     3.  Compensation.

         (a)  Base Salary. During the Employment Term, the Company will pay
Executive an annual salary of $400,000 as compensation for his services (the
"Base Salary"). The Base Salary will be paid periodically in accordance with the
Company's normal payroll practices and be subject to the usual, required
withholding. Executive's salary will be subject to review and adjustments will
be made based upon the Company's normal performance review practices.

         (b)  Sign-On Bonus. Pursuant to the provisions of the Old Employment
Agreement, Executive received a lump sum payment of $50,000 (less all applicable
withholding taxes) (the "Sign-On Bonus"). As required under Old Employment
Agreement and as modified in this Agreement, if before the earlier of (i)
September 24, 2002 or (ii) Executive's completion of the last Liquidation Task
(as defined in Section 3(c)), (A) Executive voluntarily terminates his
employment with the Company for any reason other than a reason that constitutes
an "Involuntary Termination" (as defined below), or (B) the Company terminates
Executive for Cause, then Executive must repay to the Company the entire amount
of the Sign-On Bonus.

         (c)  Performance Bonus. As of the Effective Date, Executive shall be
deemed to have earned $50,000 of his target performance bonus of $100,000. The
Company shall pay Executive such earned bonus, less applicable withholding, on
the first regular payroll date following the Effective Date. Following the
Effective Date, upon completion of each applicable Liquidation Task (as defined
below) prior to Executive's termination of employment, the Company shall, on the
first regular payroll date following the completion of such Liquidation Task,
pay to Executive a portion of the remaining target performance bonus in a
lump-sum payment equal to the amount described below. A "Liquidation Task" shall
mean one of the tasks described below in Section 3(c)(i) through (vii), each of
which the Company believes is critical to the consummation of the Liquidation
(collectively, the "Liquidation Tasks").

              (i)   Mailing of Proxy. On the date the Company mails to its
stockholders the proxy statement for the special meeting of stockholders at
which the Company's stockholders will consider a proposal to approve the
Liquidation, the Company shall pay to Executive $5,000, less applicable
withholding taxes (with payment due on the first regular payroll date following
the completion of this Liquidation Task).

              (ii)  Filing of Certificate of Dissolution. On the date the
Company files the certificate of dissolution following the date the Company's
stockholders approve the Liquidation, the Company shall pay to Executive $5,000,
less applicable withholding taxes (with payment due on the first regular payroll
date following the completion of this Liquidation Task).

              (iii) Completion of Plan for Liquidation. On the date Executive
completes a plan outlining in reasonable detail the essential elements and tasks
intended to establish that the Company and the Board have acted in due care in
consummating the Liquidation, the Company shall pay to Executive $12,500, less
applicable withholding (with payment due on the first regular payroll date
following the completion of this Liquidation Task).

              (iv)  Resolution of Leaseholds. On the date the Company reaches a
final written agreement with the landlord for its facilities at 400 Race Street,
San Jose, California with

                                       -2-

<PAGE>

respect to the Company's obligations under the lease for such facility, the
Company shall pay to Executive $5,000, less applicable withholding (with payment
due on the first regular payroll date following the completion of this
Liquidation Task).

            (v)   Employee Terminations. On the date the Company completes the
final termination of Company employees, other than those employees necessary to
assist in the consummation of the Liquidation as determined in good faith by
Executive, the Company shall pay to Executive $5,000, less applicable
withholding (with payment due on the first regular payroll date following the
completion of this Liquidation Task).

            (vi)  Initial Distribution. On the date the Company makes its
initial distribution of assets to the Company's stockholders in connection with
the Liquidation (the "Initial Distribution"), the Company shall pay to Executive
$12,500, less applicable withholding (with payment due on the first regular
payroll date following the completion of this Liquidation Task).

            (vii) Final Tax Filings. On the date the Company has provided to its
independent accountants all information reasonably requested by such accountants
in connection with the preparation of the Company's corporate tax returns and
any other tax related filings for the tax year in which the Initial Distribution
occurs, the Company shall pay to Executive $5,000, less applicable withholding
(with payment due on the first regular payroll date following the completion of
this Liquidation Task). The Company shall use its reasonable efforts to cause
its independent accountants to deliver a request for information as soon as
practicable after the Effective Date. After Executive has provided such
information as he reasonably determines satisfies this Liquidation Task, the
Company shall in writing make a final inquiry of its independent accountants
regarding their need for additional information. If the independent accountants
confirm that they have received all reasonably requested information (or fail to
respond to such inquiry within twenty (20) calendar days), then this Liquidation
Task shall be deemed completed. If the independent accountants reasonably
request additional information, then this Liquidation Task shall be deemed
completed upon delivery of such additional information.

       (d)  Stock Options.

            (i)   First Option. Pursuant to the provisions of the Old Employment
Agreement, Executive was granted a stock option to purchase 1,200,000 shares of
the Company's Common Stock at an exercise price equal to the fair market value
of such Common Stock on the date of grant (the "First Option"). Subject to the
accelerated vesting provisions set forth herein, the First Option shall continue
to vest as provided in the Old Employment Agreement (that is, as to 25% of the
shares subject to such First Option one year after its vesting commencement
date, and as to 1/48th of the shares subject to such First Option monthly
thereafter, so that the First Option will be fully vested and exercisable four
(4) years from the vesting commencement date, subject to Executive's continued
service to the Company on the relevant vesting dates). The vesting commencement
date for the First Option is the date Executive began employment with the
Company pursuant to the Old Employment Agreement. The First Option will continue
to be subject to the terms, definitions and provisions of the Company's
Nonstatutory Stock Option Plan (the "Option Plan") and the stock option
agreement executed by Executive and the Company (the "First Option Agreement"),
both of which documents have been approved by the Board and are incorporated
herein by reference.

                                       -3-

<PAGE>

            (ii)  Second Option. Pursuant to the provisions of the Old
Employment Agreement, Executive was granted a stock option to purchase 750,000
shares of the Company's Common Stock at an exercise price equal to the fair
market value of such common stock on the date of grant (the "Second Option").
The First Option together with the Second Option shall each be referred to as an
"Option" and collectively as the "Options." Subject to the accelerated vesting
provisions set forth herein, and because the Board voted that it would deem that
the Executive met the milestone for approval of Executive's business plan for
the Company (prepared jointly by the CEO, COO and CFO) by April 8, 2002, the
Second Option shall continue to vest as provided in the Old Employment Agreement
(that is, as to 25% of the shares subject to such Option eighteen (18) months
following the effective date of the Old Employment Agreement, and as to 1/48th
of the shares subject to such Option monthly thereafter, so that the Second
Option will be fully vested and exercisable fifty-four (54) months from the
effective date of the Old Employment Agreement, subject to Executive's continued
service to the Company on the relevant vesting dates). The Second Option will
continue to be subject to the terms, definitions and provisions of the Option
Plan and the stock option agreement executed by Executive and the Company (the
"Second Option Agreement"), both of which documents have been approved by the
Board and are incorporated herein by reference. The First Option Agreement
together with the Second Option Agreement shall each be referred to as the
"Option Agreement" or collectively as the "Option Agreements."

            (iii) Accelerated Vesting Upon Stockholder Meeting Date. Upon the
date on which the stockholders of the Company approve the Liquidation at a duly
noticed and held stockholders' meeting (the "Stockholders' Meeting Date"),
provided that the Stockholders' Meeting Date occurs prior to Executive's
termination of employment, the Options shall immediately vest and become
exercisable as to 100% of the shares subject to such Options, but in no event
shall the number of shares that so vest exceed the number of shares subject to
such Options. Thereafter, the Options shall continue to be bound by and be
subject to the Option Plan and Option Agreements.

            (iv)  Payment of Exercise Price. In order to facilitate payment of
the exercise price of the Options, at the request of the Executive, Executive as
borrower shall be permitted to issue to the Company a secured non-recourse
promissory note (the "Secured Note") with principal amount equal to the
aggregate exercise price of any Options exercised by the Executive plus the
amount of any withholding taxes due by Executive as a result of such exercise.
The Secured Note shall include commercially reasonable terms and shall include
the following additional terms: (i) the Secured Note shall be payable on the
date the Company makes the Initial Distribution and shall be repaid in full from
Executive's distributions received with respect to his Company Common Stock
acquired pursuant to exercise of the Options (provided, however, that if the
amount received by Executive in the Initial Distribution is less than the amount
then outstanding under the Secured Note, then the excess amount due shall not be
payable until such time as Executive receives proceeds from subsequent
distributions equal to such excess amount), (ii) the Secured Note shall bear
interest at the applicable federal rate necessary to avoid imputed income to
Executive, and (iii) the Secured Note shall be fully secured by 100% of the
shares of Company Common Stock issued upon the exercise of the Options related
thereto and any distributions received with respect to such shares in connection
with the Liquidation.

     4. Employee Benefits. During the Employment Term, Executive will be
entitled to participate in the employee benefit plans currently and hereafter
maintained by the Company of general applicability to other senior executives of
the Company, including, without limitation, the

                                       -4-

<PAGE>

Company's group medical, dental, vision, disability, life insurance, and
flexible-spending account plans. The Company reserves the right to cancel or
change the benefit plans and programs it offers to its employees at any time.

     5. Paid Time Off. Executive shall proportionately accrue paid time off of
up to eighteen (18) days per year in accordance with Company policies, with the
timing and duration of specific time off mutually and reasonably agreed to by
the parties hereto.

     6. Expenses. The Company will reimburse Executive for reasonable travel,
entertainment or other expenses incurred by Executive in the furtherance of or
in connection with the performance of Executive's duties hereunder, in
accordance with the Company's expense reimbursement policy as in effect from
time to time.

     7. Severance.

        (a) Involuntary Termination. If (i) Executive terminates his employment
with the Company due to an "Involuntary Termination" (as defined below) or (ii)
the Company terminates Executive's employment with the Company for other than
"Cause" (as defined below), death or disability, then, subject to Section 12 and
Executive signing and not revoking a standard release of claims in a form
acceptable to the Company, Executive shall be entitled to (i) receive a lump-sum
severance payment (less applicable withholding taxes) equal to his Base Salary
rate, as then in effect, over a period of twelve (12) months to be paid within
seven (7) days from the date of such termination, (ii) payment of the remaining
unearned target performance bonus, if any, as set forth in Section 3(c), as if
the Liquidation Tasks had been completed in full, (iii) immediate vesting and
exercisability of 100% of the unvested shares subject to the Options, and (iv)
continued payment by the Company of the group health continuation coverage
premiums for Executive and Executive's eligible dependents under Title X of the
Consolidated Budget Reconciliation Act of 1985, as amended ("COBRA") as in
effect through the lesser of (x) eighteen (18) months from the effective date of
such termination, (y) the date upon which Executive and Executive's eligible
dependents become covered under similar plans, or (z) the date Executive no
longer constitutes a "Qualified Beneficiary" (as such term is defined in Section
4980B(g) of the Internal Revenue Code of 1986, as amended (the "Code"));
provided, however, that Executive will be solely responsible for electing such
coverage within the required time periods.

        (b) Voluntary Termination; Termination for Cause. If Executive's
employment with the Company terminates voluntarily by Executive (other than due
to an Involuntary Termination) or for Cause by the Company, then (i) all vesting
of the Options will terminate immediately, (ii) all payments of compensation by
the Company to Executive hereunder will terminate immediately (except as to
amounts already earned), and (iii) Executive will only be eligible for severance
benefits in accordance with the Company's established policies as then in
effect.

     8. Change of Control Benefits.

        (a) Acceleration of Options Upon a Change of Control. In the event of a
Change of Control that occurs prior to Executive's termination of employment,
100% of the unvested shares subject to the Options shall immediately vest and
become exercisable. In all other respects, the

                                       -5-

<PAGE>

Options will continue to be subject to the terms, definitions and provisions of
the Option Plan and Option Agreements.

        (b) Guaranteed Payment. In the event of a Change of Control of the
Company, the Company will pay to Executive a bonus payable in cash or Company
Common Stock, as determined by the Board in its sole and absolute discretion, in
an amount, if any, equal to $1,000,000 less the amount by which the "Fair Market
Value" (as defined in the Option Plan) of the shares of the Company's Common
Stock subject to the Options exceeds the aggregate exercise price of the shares
of the Company's Common Stock subject to such Options, provided in no event
shall the amount payable to Executive exceed $1,000,000. In the event Executive
has exercised an Option but has not disposed of such exercised shares on the
effective date of a Change of Control, such shares shall be considered to still
be subject to the Option from which they were issued for purposes of determining
the bonus amount. Additionally, in the event Executive has exercised an Option
and sold or otherwise disposed of such exercised shares, the bonus amount shall
be reduced by the greater of (i) the difference between the sale price received
by Executive for such shares less the exercise price of such shares; provided,
however, that if Executive gifts any exercised shares or otherwise disposes of
such shares for consideration less than the Fair Market Value of such shares on
the date of disposition, then the shares shall be deemed to have been disposed
of for the Fair Market Value of such shares on the date of such disposition, or
(ii) the difference between the Fair Market Value of such shares on the
effective date of a Change of Control less the exercise price of such shares.

        (c) Termination Following a Change of Control. If within twelve (12)
months following a Change of Control (other than the Company's stockholders
approving the Liquidation) (i) Executive terminates his employment with the
Company due to an Involuntary Termination, or (ii) the Company terminates
Executive's employment with the Company for other than Cause, death or
disability, then, subject to Executive signing and not revoking a standard
release of claims in a form acceptable to the Company, in lieu of benefits
described in Section 7(a), Executive shall be entitled to (x) receive continuing
payments of severance pay (less applicable withholding taxes) at a rate equal to
his Base Salary rate, as then in effect, for a period of twelve (12) months from
the date of such termination, to be paid periodically in accordance with the
Company's normal payroll policies, (y) continued payment by the Company of the
group health continuation coverage premiums for Executive and Executive's
eligible dependents under COBRA as in effect through the lesser of (A) twelve
(12) months from the effective date of such termination, (B) the date upon which
Executive and Executive's eligible dependents become covered under similar
plans, or (C) the date Executive no longer constitutes a Qualified Beneficiary;
provided, however, that Executive will be solely responsible for electing such
coverage within the required time periods, and (z) exercise the Options, to the
extent vested, for a period of one (1) year following such termination or such
longer period as may be provided for in the applicable Option Agreement.

        (d) Voluntary Termination; Termination for Cause. If within the twelve
(12) months following a Change of Control Executive's employment with the
Company terminates voluntarily by Executive (other than due to an Involuntary
Termination) or for Cause by the Company, then (i) all vesting of the Options
will terminate immediately, (ii) all payments of compensation by the Company to
Executive hereunder will terminate immediately (except as to amounts already
earned), and (iii) Executive will only be eligible for severance benefits in
accordance with the Company's established policies as then in effect.

                                       -6-

     9.   Limitation on Payments. In the event that the severance and other
benefits provided for in this Agreement or otherwise payable to the Executive
(i) constitute "parachute payments" within the meaning of Section 280G of the
Code and (ii) but for this Section 9, would be subject to the excise tax imposed
by Section 4999 of the Code, then the Executive's severance benefits under
Sections 7 or 8 shall be either:

          (a)    delivered in full, or

          (b)    delivered as to such lesser extent 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 Executive on an after-tax basis, of
the greatest amount of severance benefits, notwithstanding that all or some
portion of such severance benefits may be taxable under Section 4999 of the
Code. Unless the Company and the Executive otherwise agree in writing, any
determination required under this Section 9 shall be made in writing by an
independent public accountant selected by the Company, immediately prior to
Change of Control (the "Accountants"), whose determination shall be conclusive
and binding upon the Executive and the Company for all purposes. For purposes of
making the calculations required by this Section 9, 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 Executive 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 9.

     10.  Definitions.

          (a)    Cause. For purposes of this Agreement, "Cause" is defined as
(i) an act of dishonesty made by Executive in connection with Executive's
responsibilities as an employee, (ii) Executive's conviction of, or plea of nolo
contendere to, a felony, (iii) Executive's gross misconduct, or (iv) Executive's
continued substantial violations of his employment duties after Executive has
received a written demand for performance from the Company which specifically
sets forth the factual basis for the Company's belief that Executive has not
substantially performed his duties.

          (b)    Change of Control. For purposes of this Agreement, "Change of
Control" of the Company is defined as:

                 (i)    any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes 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; or

                 (ii)   a change in the composition of the Board occurring
within a two-year period, as a result of which fewer than a majority of the
directors are Incumbent Directors. "Incumbent Directors" will mean directors who
either (A) are directors of the Company as of the date hereof, or (B) are
elected, or nominated for election, to the Board with the affirmative votes of

                                       -7-

<PAGE>

at least a majority of the Incumbent Directors at the time of such election or
nomination (but will not include an individual whose election or nomination is
in connection with an actual or threatened proxy contest relating to the
election of directors to the Company); or

                 (iii)  the date of the consummation of a merger or
consolidation of the Company with any other corporation that has been approved
by the stockholders of the Company, 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) more than 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 stockholders of the Company approve a plan of complete
liquidation of the Company; or

                 (iv)   the date of the consummation of the sale or disposition
by the Company of all or substantially all the Company's assets.

          (c)    Involuntary Termination. For purposes of this Agreement,
"Involuntary Termination" shall mean without the Executive's express written
consent (i) a significant reduction of the Executive's duties, position or
responsibilities, or the removal of the Executive from such position and
responsibilities, unless the Executive 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 in duties,
position or responsibilities solely by virtue of (A) the Liquidation, or (B) the
Company being acquired and made part of a larger entity (as, for example, when
the Chief Executive Officer of the Company remains as such following a Change of
Control but is not made the Chief Executive Officer of the acquiring
corporation) shall not constitute an "Involuntary Termination"; (ii) a
significant reduction by the Company in the Base Salary of the Executive as in
effect immediately prior to such reduction; (iii) a material reduction by the
Company in the kind or level of employee benefits to which the Executive is
entitled immediately prior to such reduction with the result that the
Executive's overall benefits package is significantly reduced, except for any
reductions directly related to, or as the result of, the Liquidation; (iv) the
relocation of the Executive to a facility or a location more than fifty (50)
miles from the Executive's then present location, or (v) the completion of all
of the Liquidation Tasks as set forth in Section 3(c).

     11.  Confidential Information. Executive entered into the Company's
standard Confidential Information and Invention Assignment Agreement (the
"Confidential Information Agreement") upon commencing employment hereunder,
which such agreement is incorporated herein by reference.

                                       -8-

<PAGE>

     12.  Conditional Nature of Severance Payments.

          (a)    Noncompete. To avoid the inevitable disclosure of the Company's
trade secrets and confidential information, Executive agrees and acknowledges
that Executive's right to receive the severance payments set forth in Sections 7
and 8 (to the extent Executive is otherwise entitled to such payments) shall be
conditioned upon Executive not directly or indirectly engaging in (whether as an
employee, consultant, agent, proprietor, principal, partner, stockholder,
corporate officer, director or otherwise), nor having any ownership interested
in or participating in the financing, operation, management or control of, any
person, firm, corporation or business that competes with Company or is a
customer of the Company. Upon any breach of this section, all severance payments
pursuant to this Agreement shall immediately cease.

          (b)    Non-Solicitation. Until the date one (1) year after the
termination of Executive's employment with the Company for any reason, Executive
agrees not, either directly or indirectly, to solicit, induce, attempt to hire,
recruit, encourage, take away, hire any employee of the Parent or the Company or
cause an employee to leave his or her employment either for Executive or for any
other entity or person. Additionally, Executive acknowledges that Executive's
right to receive the severance payments set forth in Sections 7 and 8 (to the
extent Executive is otherwise entitled to such payments) are contingent upon
Executive complying with this Section 12(b) and upon any breach of this section
all severance payments pursuant to this Agreement shall immediately cease.

          (c)    Understanding of Covenants. Executive represents that he (i) is
familiar with the foregoing covenants not to compete and not to solicit, and
(ii) is fully aware of his obligations hereunder, including, without limitation,
the reasonableness of the length of time, scope and geographic coverage of these
covenants.

     13.  Assignment. This Agreement will be binding upon and inure to the
benefit of (a) the heirs, executors and legal representatives of Executive upon
Executive's death and (b) any successor of the Company. Any such successor of
the Company will be deemed substituted for the Company under the terms of this
Agreement for all purposes. For this purpose, "successor" means any person,
firm, corporation or other business entity which at any time, whether by
purchase, merger or otherwise, directly or indirectly acquires all or
substantially all of the assets or business of the Company. None of the rights
of Executive to receive any form of compensation payable pursuant to this
Agreement may be assigned or transferred except by will or the laws of descent
and distribution. Any other attempted assignment, transfer, conveyance or other
disposition of Executive's right to compensation or other benefits will be null
and void.

     14.  Notices. All notices, requests, demands and other communications
called for hereunder shall be in writing and shall be deemed given (i) on the
date of delivery if delivered personally, (ii) one (1) day after being sent by a
well established commercial overnight service, or (iii) four (4) days after
being mailed by registered or certified mail, return receipt requested, prepaid
and addressed to the parties or their successors at the following addresses, or
at such other addresses as the parties may later designate in writing:

          If to the Company:

          400 Race Street
          San Jose, CA 95126
          Attn: President

          If to Executive:

          at the last residential address known by the Company.

     15.  Severability.  In the event that any  provision  hereof  becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement will continue in full force and effect without said
provision.

     16.  Arbitration.

          (a)    General. In consideration of Executive's service to the
Company, its promise to arbitrate all employment related disputes and
Executive's receipt of the compensation, pay raises and other benefits paid to
Executive by the Company, at present and in the future, Executive agrees that
any and all controversies, claims, or disputes with anyone (including the
Company and any employee, officer, director, shareholder or benefit plan of the
Company in their capacity as such or otherwise) arising out of, relating to, or
resulting from Executive's service to the Company under this Agreement or
otherwise or the termination of Executive's service with the Company, including
any breach of this Agreement, shall be subject to binding arbitration under the
Arbitration Rules set forth in California Code of Civil Procedure Section 1280
through 1294.2, including Section 1283.05 (the "Rules") and pursuant to
California law. Disputes which Executive agrees to arbitrate, and thereby agrees
to waive any right to a trial by jury, include any statutory claims under state
or federal law, including, but not limited to, claims under Title VII of the
Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age
Discrimination in Employment Act of 1967, the Older Workers Benefit Protection
Act, the California Fair Employment and Housing Act, the California Labor Code,
claims of harassment, discrimination or wrongful termination and any statutory
claims. Executive further understands that this Agreement to arbitrate also
applies to any disputes that the Company may have with Executive.

          (b)    Procedure. Executive agrees that any arbitration will be
administered by the American Arbitration Association ("AAA") and that a neutral
arbitrator will be selected in a manner consistent with its National Rules for
the Resolution of Employment Disputes. The arbitration proceedings will allow
for discovery according to the rules set forth in the National Rules for the
Resolution of Employment Disputes or California Code of Civil Procedure.
Executive agrees that the arbitrator shall have the power to decide any motions
brought by any party to the arbitration, including motions for summary judgment
and/or adjudication and motions to dismiss and demurrers, prior to any
arbitration hearing. Executive agrees that the arbitrator shall issue a written
decision on the merits. Executive also agrees that the arbitrator shall have the
power to award any remedies, including attorneys' fees and costs, available
under applicable law. Executive understands the Company will pay for any
administrative or hearing fees charged by the arbitrator or AAA except that
Executive shall pay the first $200.00 of any filing fees associated with any
arbitration Executive initiates. Executive agrees that the arbitrator shall
administer and conduct any arbitration in a

                                      -10-

<PAGE>

manner consistent with the Rules and that to the extent that the AAA's National
Rules for the Resolution of Employment Disputes conflict with the Rules, the
Rules shall take precedence.

          (c)    Remedy. Except as provided by the Rules, arbitration shall be
the sole, exclusive and final remedy for any dispute between Executive and the
Company. Accordingly, except as provided for by the Rules, neither Executive nor
the Company will be permitted to pursue court action regarding claims that are
subject to arbitration. Notwithstanding, the arbitrator will not have the
authority to disregard or refuse to enforce any lawful Company policy, and the
arbitrator shall not order or require the Company to adopt a policy not
otherwise required by law which the Company has not adopted.

          (d)    Availability of Injunctive Relief. In addition to the right
under the Rules to petition the court for provisional relief, Executive agrees
that any party may also petition the court for injunctive relief where either
party alleges or claims a violation of this Agreement or the Confidentiality
Agreement or any other agreement regarding trade secrets, confidential
information, nonsolicitation or Labor Code ss.2870. In the event either party
seeks injunctive relief, the prevailing party shall be entitled to recover
reasonable costs and attorneys' fees.

          (e)    Administrative Relief. Executive understands that this
Agreement does not prohibit Executive from pursuing an administrative claim with
a local, state or federal administrative body such as the Department of Fair
Employment and Housing, the Equal Employment Opportunity Commission or the
workers' compensation board. This Agreement does, however, preclude Executive
from pursuing court action regarding any such claim.

          (f)    Voluntary Nature of Agreement. Executive acknowledges and
agrees that Executive is executing this Agreement voluntarily and without any
duress or undue influence by the Company or anyone else. Executive further
acknowledges and agrees that Executive has carefully read this Agreement and
that Executive has asked any questions needed for Executive to understand the
terms, consequences and binding effect of this Agreement and fully understand
it, including that Executive is waiving Executive's right to a jury trial.
Finally, Executive agrees that Executive has been provided an opportunity to
seek the advice of an attorney of Executive's choice before signing this
Agreement.

     17.  Attorneys' Fees. The Company shall reimburse Executive for attorneys'
fees incurred by Executive with respect to implementation and execution of this
Agreement, not to exceed $10,000, upon Executive's submission of receipts or
other reasonable documentation supporting such fees.

     18.  Integration. This Agreement, together with the Option Plan, Option
Agreements and the Confidential Information Agreement, represent the entire
agreement and understanding between the parties as to the subject matter herein
and supersede all prior or contemporaneous agreements whether written or oral,
including the Old Employment Agreement. No waiver, alteration, or modification
of any of the provisions of this Agreement will be binding unless in writing and
signed by duly authorized representatives of the parties hereto.

                                      -11-

<PAGE>

     19.  Waiver of Breach. The waiver of a breach of any term or provision of
this Agreement, which must be in writing, shall not operate as or be construed
to be a waiver of any other previous or subsequent breach of this Agreement.

     20.  Headings. All captions and section headings used in this Agreement are
for convenient reference only and do not form a part of this Agreement.
