1.      PURPOSES.

        (a) ELIGIBLE OPTION RECIPIENTS. The persons eligible to receive Options
are the Non-Employee Directors of the Company.

        (b) AVAILABLE OPTIONS. The purpose of the Plan is to provide a means by
which Non-Employee Directors may be given an opportunity to benefit from
increases in value of the Common Stock through the granting of Nonstatutory
Stock Options.

        (c) GENERAL PURPOSE. The Company, by means of the Plan, seeks to retain
the services of its Non-Employee Directors, to secure and retain the services of
new Non-Employee Directors and to provide incentives for such persons to exert
maximum efforts for the success of the Company and its Affiliates.

2.      DEFINITIONS.

Directors who meet the specified criteria pursuant to subsection 6(b) of the

renders such service, provided that there is no interruption or termination of
the Optionholder's Continuous Service. For example, a change in status from a

amended.

        (n) "FAIR MARKET VALUE" means, as of any date, the value of the Common
Stock determined as follows:

exchange or traded on the Nasdaq National Market or the Nasdaq SmallCap Market,
the Fair Market Value of a share of Common Stock shall be the closing sales
price for such stock (or the closing bid, if no sales were reported) as quoted
on such exchange or market (or the exchange or market with the greatest volume
of trading in the Common Stock) on the last market trading day prior to the day
of determination, as reported in The Wall Street Journal or such other source as

it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Option Agreement, in a
manner and to the extent it shall deem necessary or expedient to make the Plan
fully effective.

               (iv) Generally, to exercise such powers and to perform such acts
as the Board deems necessary or expedient to promote the best interests of the
Company that are not in conflict with the provisions of the Plan.

        (c) EFFECT OF BOARD'S DECISION. All determinations, interpretations and
constructions made by the Board in good faith shall not be subject to review by
any person and shall be final, binding and conclusive on all persons.

4.      SHARES SUBJECT TO THE PLAN.

        (a) SHARE RESERVE. Subject to the provisions of Section 11 relating to
adjustments upon changes in the Common Stock, the Common Stock that may be
issued pursuant to Options shall not exceed in the aggregate Three Hundred
Thousand (300,000) shares of Common Stock.

        (b) EVERGREEN SHARE RESERVE INCREASE.

               (i) Notwithstanding subsection 4(a) hereof, on the day after each
Annual Meeting (the "Calculation Date") for a period of ten (10) years,
commencing with the Annual Meeting in 2000, the aggregate number of shares of
Common Stock that is available for issuance under the Plan shall automatically
be increased by that number of shares equal to the greater of (1) three-tenths
of one percent (0.3%) of the Diluted Shares Outstanding or (2) the number of
shares of Common Stock subject to Options granted during the prior 12-month
period; provided, however, that the Board, from time to time, may provide for a
lesser increase in the aggregate number of shares of Common Stock that is
available for issuance under the Plan

               (ii) "Diluted Shares Outstanding" shall mean, as of any date, (1)
the number of outstanding shares of Common Stock of the Company on such
Calculation Date, plus (2) the number of shares of Common Stock issuable upon
such Calculation Date assuming the conversion of all outstanding Preferred Stock
and convertible notes, plus (3) the additional number of dilutive Common Stock
equivalent shares outstanding as the result of any options or warrants
outstanding during the fiscal year, calculated using the treasury stock method.

        (c) REVERSION OF SHARES TO THE SHARE RESERVE. If any Option shall for
any reason expire or otherwise terminate, in whole or in part, without having
been exercised in full, the shares of Common Stock not acquired under such
Option shall revert to and again become available for issuance under the Plan.

        (d) SOURCE OF SHARES. The shares of Common Stock subject to the Plan may
be unissued shares or reacquired shares, bought on the market or otherwise.


                                       4
<PAGE>   5

5.      ELIGIBILITY.

        The Options as set forth in section 6 automatically shall be granted
under the Plan to all Non-Employee Directors.

6.      NON-DISCRETIONARY GRANTS.

        (a) INITIAL GRANTS. Without any further action of the Board, each person
who is elected or appointed for the first time to be a Non-Employee Director
automatically shall, upon the date of his or her initial election or appointment
to be a Non-Employee Director, be granted an Initial Grant to purchase Twenty
Thousand (20,000) shares of Common Stock on the terms and conditions set forth
herein.

        (b) ANNUAL GRANTS. Without any further action of the Board, on the day
following each Annual Meeting, commencing with the Annual Meeting in 2001, each
person who is then a Non-Employee Director, and has been a Non-Employee Director
for at least six (6) months, automatically shall be granted an Annual Grant to
purchase Five Thousand (5,000) shares of Common Stock on the terms and
conditions set forth herein.

7.      OPTION PROVISIONS.

        Each Option shall be in such form and shall contain such terms and
conditions as required by the Plan. Each Option shall contain such additional
terms and conditions, not inconsistent with the Plan, as the Board shall deem
appropriate. Each Option shall include (through incorporation of provisions
hereof by reference in the Option or otherwise) the substance of each of the
following provisions:

        (a) TERM. No Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

        (b) EXERCISE PRICE. The exercise price of each Option shall be one
hundred percent (100%) of the Fair Market Value of the stock subject to the
Option on the date the Option is granted. Notwithstanding the foregoing, an
Option may be granted with an exercise price lower than that set forth in the
preceding sentence if such Option is granted pursuant to an assumption or
substitution for another option in a manner satisfying the provisions of Section
424(a) of the Code.

        (c) CONSIDERATION. The purchase price of stock acquired pursuant to an
Option may be paid, to the extent permitted by applicable statutes and
regulations, in any combination of (i) cash or check, (ii) delivery to the
Company of other Common Stock or (iii) pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve Board that, prior to the
issuance of Common Stock, results in either the receipt of cash (or check) by
the Company or the receipt of irrevocable instructions to pay the aggregate
exercise price to the Company from the sales proceeds. The purchase price of
Common Stock acquired pursuant to an Option that is paid by delivery to the
Company of other Common Stock acquired, directly or indirectly from the Company,
shall be paid only by shares of the Common Stock of the Company that have been


                                       5
<PAGE>   6

held for more than six (6) months (or such longer or shorter period of time
required to avoid a charge to earnings for financial accounting purposes).

        (d) TRANSFERABILITY. An Option is transferable by will or by the laws of
descent and distribution. An Option also is transferable if, at the time of
transfer, a Form S-8 registration statement under the Securities Act is
available for the exercise of the Option and the subsequent resale of the
underlying securities.1 In addition, Optionholder may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionholder, shall thereafter be
entitled to exercise the Option.

        (e) VESTING. Options shall vest as follows:

               (i) Initial Grants shall provide for vesting of 1/36th of the
shares subject to the Option each month for three (3) years after the date of
the grant.

               (ii) Annual Grants shall provide for vesting of 1/12th of the
shares subject to the Option each month for one (1) year after the date of the
grant.

        (f) EXERCISE. Options shall be exercisable in full immediately upon
grant.

        (g) TERMINATION OF CONTINUOUS SERVICE. In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent that
the Optionholder was entitled to exercise it as of the date of termination) but
only within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Optionholder's Continuous Service, or
(ii) the expiration of the term of the Option as set forth in the Option
Agreement. If, after termination, the Optionholder does not exercise his or her
Option within the time specified in the Option Agreement, the Option shall
terminate.

        (h) EXTENSION OF TERMINATION DATE. If the exercise of the Option
following the termination of the Optionholder's Continuous Service (other than
upon the Optionholder's death or Disability) would be prohibited at any time
solely because the issuance of shares would violate the registration
requirements under the Securities Act, then the Option shall terminate on the
earlier of (i) the expiration of the term of the Option set forth in subsection
7(a) or (ii) the

----------

(1) See the General Instructions to the Form S-8 Registration Statement, Rule
A.1.(5). Currently a Form S-8 is available for the exercise of the Option and
the subsequent resale of the underlying securities by the Optionholder's family
member who has acquired the Option from the Optionholder through a gift or a
domestic relations order. For purposes of Form S-8, "family member" currently
includes any child, stepchild, grandchild, parent, stepparent, grandparent,
spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law,
son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including
adoptive relationships, any person sharing the Optionholder's household (other
than a tenant or employee), a trust in which these persons have more than fifty
percent (50%) of the beneficial interest, a foundation in which these persons
(or the Optionholder) control the management of assets, and any other entity in
which these persons (or the Optionholder) own more than fifty percent (50%) of
the voting interests. Form S-8 currently is not available for the exercise of an
Option transferred for value. The following transactions currently are not
prohibited transfers for value: (i) a transfer under a domestic relations order
in settlement of marital property rights; and (ii) a transfer to an entity in
which more than fifty percent (50%) of the voting interests are owned by family
members (or the Optionholder) in exchange for an interest in that entity.


                                       6
<PAGE>   7

expiration of a period of three (3) months after the termination of the
Optionholder's Continuous Service during which the exercise of the Option would
not be in violation of such registration requirements.

        (i) DISABILITY OF OPTIONHOLDER. In the event an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise it as of the date of termination), but only within such
period of time ending on the earlier of (i) the date twelve (12) months
following such termination or (ii) the expiration of the term of the Option as
set forth in the Option Agreement. If, after termination, the Optionholder does
not exercise his or her Option within the time specified herein, the Option
shall terminate.

        (j) DEATH OF OPTIONHOLDER. In the event (i) an Optionholder's Continuous
Service terminates as a result of the Optionholder's death or (ii) the
Optionholder dies within the three-month period after the termination of the
Optionholder's Continuous Service for a reason other than death, then the Option
may be exercised (to the extent the Optionholder was entitled to exercise the
Option as of the date of death) by the Optionholder's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the Option upon the Optionholder's death, but only
within the period ending on the earlier of (1) the date eighteen (18) months
following the date of death or (2) the expiration of the term of such Option as
set forth in the Option Agreement. If, after death, the Option is not exercised
within the time specified herein, the Option shall terminate.

8.      COVENANTS OF THE COMPANY.

        (a) AVAILABILITY OF SHARES. During the terms of the Options, the Company
shall keep available at all times the number of shares of Common Stock required
to satisfy such Options.

        (b) SECURITIES LAW COMPLIANCE. The Company shall seek to obtain from
each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to grant Options and to issue and sell shares of
Common Stock upon exercise of the Options; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Option or any stock issued or issuable pursuant to any such
Option. If, after reasonable efforts, the Company is unable to obtain from any
such regulatory commission or agency the authority which counsel for the Company
deems necessary for the lawful issuance and sale of stock under the Plan, the
Company shall be relieved from any liability for failure to issue and sell stock
upon exercise of such Options unless and until such authority is obtained.

9.      USE OF PROCEEDS FROM STOCK.

        Proceeds from the sale of stock pursuant to Options shall constitute
general funds of the Company.


                                       7
<PAGE>   8

10.     MISCELLANEOUS.

        (a) STOCKHOLDER RIGHTS. No Optionholder shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares subject
to such Option unless and until such Optionholder has satisfied all requirements
for exercise of the Option pursuant to its terms.

        (b) NO SERVICE RIGHTS. Nothing in the Plan or any instrument executed or
Option granted pursuant thereto shall confer upon any Optionholder any right to
continue to serve the Company as a Non-Employee Director or shall affect the
right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of a
Consultant pursuant to the terms of such Consultant's agreement with the Company
or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the
Company or an Affiliate, and any applicable provisions of the corporate law of
the state in which the Company or the Affiliate is incorporated, as the case may
be.

        (c) INVESTMENT ASSURANCES. The Company may require an Optionholder, as a
condition of exercising or acquiring stock under any Option, (i) to give written
assurances satisfactory to the Company as to the Optionholder's knowledge and
experience in financial and business matters and/or to employ a purchaser
representative reasonably satisfactory to the Company who is knowledgeable and
experienced in financial and business matters and that he or she is capable of
evaluating, alone or together with the purchaser representative, the merits and
risks of exercising the Option; and (ii) to give written assurances satisfactory
to the Company stating that the Optionholder is acquiring the stock subject to
the Option for the Optionholder's own account and not with any present intention
of selling or otherwise distributing the stock. The foregoing requirements, and
any assurances given pursuant to such requirements, shall be inoperative if
(iii) the issuance of the shares upon the exercise or acquisition of stock under
the Option has been registered under a then currently effective registration
statement under the Securities Act or (iv) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock.

        (d) WITHHOLDING OBLIGATIONS. The Optionholder may satisfy any federal,
state or local tax withholding obligation relating to the exercise or
acquisition of stock under an Option by any of the following means (in addition
to the Company's right to withhold from any compensation paid to the
Optionholder by the Company) or by a combination of such means: (i) tendering a
cash payment; (ii) authorizing the Company to withhold shares from the shares of
the Common Stock otherwise issuable to the Optionholder as a result of the
exercise or acquisition of stock under the Option, provided, however, that no
shares of Common Stock are withheld with a value exceeding the minimum amount of
tax required to be withheld by law; or (iii) delivering to the Company owned and
unencumbered shares of the Common Stock.

<PAGE>   9

11.     ADJUSTMENTS UPON CHANGES IN STOCK.

        (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the stock
subject to the Plan, or subject to any Option, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject both to the
Plan pursuant to subsection 4(a) and to the nondiscretionary Options specified
in Section 5, and the outstanding Options will be appropriately adjusted in the
class(es) and number of securities and price per share of stock subject to such
outstanding Options. The Board shall make such adjustments, and its
determination shall be final, binding and conclusive. (The conversion of any
convertible securities of the Company shall not be treated as a transaction
"without receipt of consideration" by the Company.)

        (b) DISSOLUTION OR LIQUIDATION. In the event of a dissolution or
liquidation of the Company, then all outstanding Options shall terminate
immediately prior to such event.

        (c) ASSET SALE, MERGER, CONSOLIDATION OR REVERSE MERGER.

               (i) In the event of (i) a sale, lease or other disposition of all
or substantially all of the assets of the Company, (ii) a merger or
consolidation in which the Company is not the surviving corporation or (iii) a
reverse merger in which the Company is the surviving corporation but the shares
of Common Stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash or otherwise (collectively, a "change in control"), then any surviving
corporation or acquiring corporation shall assume any Options outstanding under
the Plan or shall substitute similar Options (including an option to acquire the
same consideration paid to the stockholders in the change in control transaction
for those outstanding under the Plan).

               (ii) In the event any surviving corporation or acquiring
corporation refuses to assume such Options or to substitute similar Options for
those outstanding under the Plan, then the vesting of such Options and the
vesting of any shares of Common Stock acquired pursuant to such Options shall be
accelerated in full, and the Options shall terminate if not exercised at or
prior to the change in control.

               (iii) In the event any surviving corporation or acquiring
corporation assumes such Options or substitutes similar Options for those
outstanding under the Plan but the Optionholder is not elected or appointed to
the board of directors of the surviving corporation or acquiring corporation at
the first meeting of such board of directors after the change in control, then
the vesting of such Options and the vesting of any shares of Common Stock
acquired pursuant to such Options shall be accelerated by eighteen (18) months
on the day after the first meeting of the board of directors of the surviving
corporation or acquiring corporation.


                                       9
<PAGE>   10

               (iv) In the event any surviving corporation or acquiring
corporation assumes such Options or substitutes similar Options for those
outstanding under the Plan and the Optionholder is elected or appointed to the
board of directors of the surviving corporation or acquiring corporation at the
first meeting of such board of directors after the change in control, then the
vesting of such Options and the vesting of any shares of Common Stock acquired
pursuant to such Options shall not be accelerated.

12.     AMENDMENT OF THE PLAN AND OPTIONS.

        (a) AMENDMENT OF PLAN. The Board at any time, and from time to time, may
amend the Plan. However, except as provided in Section 11 relating to
adjustments upon changes in stock, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary to satisfy the requirements of Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

        (b) STOCKHOLDER APPROVAL. The Board may, in its sole discretion, submit
any other amendment to the Plan for stockholder approval.

        (c) NO IMPAIRMENT OF RIGHTS. Rights under any Option granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the Optionholder and (ii) the
Optionholder consents in writing.

        (d) AMENDMENT OF OPTIONS. The Board at any time, and from time to time,
may amend the terms of any one or more Options; provided, however, that the
rights under any Option shall not be impaired by any such amendment unless (i)
the Company requests the consent of the Optionholder and (ii) the Optionholder
consents in writing.

13.     TERMINATION OR SUSPENSION OF THE PLAN.

        (a) PLAN TERM. The Board may suspend or terminate the Plan at any time.
No Options may be granted under the Plan while the Plan is suspended or after it
is terminated.

        (b) NO IMPAIRMENT OF RIGHTS. Suspension or termination of the Plan shall
not impair rights and obligations under any Option granted while the Plan is in
effect except with the written consent of the Optionholder.

14.     EFFECTIVE DATE OF PLAN.

        The Plan shall become effective on the IPO Date, but no Option shall be
exercised unless and until the Plan has been approved by the stockholders of the
Company, which approval shall be within twelve (12) months before or after the
date the Plan is adopted by the Board.

                            INTUITIVE SURGICAL, INC.
                 2000 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

                             STOCK OPTION AGREEMENT
                           (NONSTATUTORY STOCK OPTION)


      Pursuant to your Stock Option Grant Notice ("Grant Notice") and this Stock
Option Agreement, Intuitive Surgical, Inc. (the "Company") has granted you an
option under its 2000 Non-Employee Directors' Stock Option Plan (the "Plan") to
purchase the number of shares of the Company's Common Stock indicated in your
Grant Notice at the exercise price indicated in your Grant Notice. Defined terms
not explicitly defined in this Stock Option Agreement but defined in the Plan
shall have the same definitions as in the Plan.

      The details of your option are as follows:

      1. VESTING. Subject to the limitations contained herein, your option will
vest as provided in your Grant Notice, provided that vesting will cease upon the
termination of your Continuous Service.

      2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of Common
Stock subject to your option and your exercise price per share referenced in
your Grant Notice may be adjusted from time to time for Capitalization
Adjustments, as provided in the Plan.

      3. EXERCISE PRIOR TO VESTING ("EARLY EXERCISE"). As permitted in your
Grant Notice (i.e., the "Exercise Schedule" indicates that "Early Exercise" of
your option is permitted) and subject to the provisions of your option, you may
elect at any time that is both (i) during the period of your Continuous Service
and (ii) during the term of your option, to exercise all or part of your option,
including the nonvested portion of your option; provided, however, that:

            (a) a partial exercise of your option shall be deemed to cover first
vested shares of Common Stock and then the earliest vesting installment of
unvested shares of Common Stock;

            (b) any shares of Common Stock so purchased from installments that
have not vested as of the date of exercise shall be subject to the purchase
option in favor of the Company as described in the Company's form of Early
Exercise Stock Purchase Agreement; and

            (c) you shall enter into the Company's form of Early Exercise Stock
Purchase Agreement with a vesting schedule that will result in the same vesting
as if no early exercise had occurred.

      4. METHOD OF PAYMENT. Payment of the exercise price is due in full upon
exercise of all or any part of your option. You may elect to make payment of the
exercise price in cash or by check or by one or more of the following:



                                       1
<PAGE>   13
            (a) Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, pursuant to a
program developed under Regulation T as promulgated by the Federal Reserve Board
that, prior to the issuance of Common Stock, results in either the receipt of
cash (or check) by the Company or the receipt of irrevocable instructions to pay
the aggregate exercise price to the Company from the sales proceeds.

            (b) Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery of
already-owned shares of Common Stock either that you have held for the period
required to avoid a charge to the Company's reported earnings (generally six
months) or that you did not acquire, directly or indirectly from the Company,
that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise.
"Delivery" for these purposes, in the sole discretion of the Company at the time
you exercise your option, shall include delivery to the Company of your
attestation of ownership of such shares of Common Stock in a form approved by
the Company. Notwithstanding the foregoing, you may not exercise your option by
tender to the Company of Common Stock to the extent such tender would violate
the provisions of any law, regulation or agreement restricting the redemption of
the Company's stock.

      5. WHOLE SHARES. You may exercise your option only for whole shares of
Common Stock.

      6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, you may not exercise your option unless the shares of Common
Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise of your option must also comply
with other applicable laws and regulations governing your option, and you may
not exercise your option if the Company determines that such exercise would not
be in material compliance with such laws and regulations.

      7. TERM. The term of your option commences on the Date of Grant and
expires upon the EARLIEST of the following:

            (a) three (3) months after the termination of your Continuous
Service for any reason other than your Disability or death, provided that if
during any part of such three- (3-) month period your option is not exercisable
solely because of the condition set forth in the preceding paragraph relating to
"Securities Law Compliance," your option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service;

            (b) twelve (12) months after the termination of your Continuous
Service due to your Disability;

            (c) eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates; or

            (d) the Expiration Date indicated in your Grant Notice; or

            (e) the day before the tenth (10th) anniversary of the Date of
Grant.

      8. EXERCISE.

            (a) You may exercise your option during its term by delivering a
Notice of Exercise (in a form designated by the Company) together with the
exercise price to the Secretary of the Company, or to such other person as the
Company may designate, during regular business hours, together with such
additional documents as the Company may then require.

            (b) By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of the exercise of your
option.

      9. TRANSFERABILITY. Your option is not transferable, except (i) by will or
by the laws of descent and distribution, or (ii) as permitted under the Form S-8
registration statement regulations in effect at the time of the transfer.(1)
Your option is exercisable during your life only by you or a transferee
satisfying the above-stated conditions. The right of a transferee to exercise
the transferred portion of your option after termination of your Continuous
Service shall terminate in accordance with your right to exercise your option as
specified in your option. In the event that your Continuous Service terminates
due to your death, your transferee will be treated as a person who acquired the
right to exercise your option by bequest or inheritance. In addition to the
foregoing, the Company may require, as a condition of the transfer of your
option to a trust or by gift, that your transferee enter into an option transfer
agreement provided by, or acceptable to, the Company. The terms of your option
shall be binding upon your transferees, executors, administrators, heirs,
successors, and assigns. Notwithstanding the foregoing, by delivering written
notice to the Company, in a form satisfactory to the Company, you may designate
a third party who, in the event of your death, shall thereafter be entitled to
exercise your option.


--------
(1) See the General Instructions to the Form S-8 Registration Statement, Rule
A.1.(5). Currently a Form S-8 is available for the exercise of your option and
the subsequent resale of the underlying securities by your family member who has
acquired your option from you through a gift or a domestic relations order. For
purposes of Form S-8, "family member" currently includes any child, stepchild,
grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling,
niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law,
brother-in-law, or sister-in-law, including adoptive relationships, any person
sharing your household (other than a tenant or employee), a trust in which these
persons have more than fifty percent (50%) of the beneficial interest, a
foundation in which these persons (or you) control the management of assets, and
any other entity in which these persons (or you) own more than fifty percent
(50%) of the voting interests. Form S-8 currently is not available for the
exercise of an option transferred for value. The following transactions
currently are not prohibited transfers for value: (i) a transfer under a
domestic relations order in settlement of marital property rights; and (ii) a
transfer to an entity in which more than fifty percent (50%) of the voting
interests are owned by family members (or you) in exchange for an interest in
that entity.

      10. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or
service contract, and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an
Affiliate, their respective stockholders, Boards of Directors, Officers or
Employees to continue any relationship that you might have as a Director or
Consultant for the Company or an Affiliate.

      11. NOTICES. Any notices provided for in your option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by mail by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

      12. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your option, and
is further subject to all interpretations, amendments, rules and regulations
which may from time to time be promulgated and adopted pursuant to the Plan. In
the event of any conflict between the provisions of your option and those of the
Plan, the provisions of the Plan shall control.
