                                      -3-
<PAGE>

                        (ii)  Section 162(m). To the extent that the
                              --------------
Administrator determines it to be desirable to qualify Options granted hereunder
as "performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administrated by a Committee of two or more "outside
directors" within the meaning of Sectiion 162(m) of the Code.

                        (iii)  Rule 16b-3. To the extent desirable to qualify
                               ----------
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.

                        (iv)   Other Administration. Other than as provided
                               --------------------
above, the Plan shall be administered by (A) the Board or (B) a Committee, which
committee shall be constituted to satisfy Applicable Laws.

             (b)  Powers of the Administrator. Subject to the provisions of the
                  ---------------------------
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                        (i)  to determine the Fair Market Value;

                       (ii)  to select the Service Providers to whom Options may
be granted hereunder;

                      (iii)  to determine the number of shares of Common Stock
to be covered by each Option granted hereunder;

                       (iv)  to approve forms of agreement for use under the
Plan;

                        (v)  to determine the terms and conditions, not
inconsistent with the terms of the Plan or any Option granted hereunder. Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                       (vi)  to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                      (vii)  to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of satisfying applicable foreign laws;

                     (viii)  to modify or amend each Option (subject to Section
14(c) of the Plan), including the discretionary authority to extend the post-
termination exercisability period of Options longer than is otherwise provided
for in the Plan;

                       (ix)  to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market

                                      -4-
<PAGE>

Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined. All elections by an Optionee
to have Shares withheld for this purpose shall be made in such form and under
such conditions as the Administrator may deem necessary or advisable;

                        (x)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option previously
granted by the Administrator;

                       (xi)  to make all other determinations deemed necessary
or advisable for administering the Plan.

            (c)  Effect of Administrator's Decision. The Administrator's
                 ----------------------------------
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

        5.  Eligibility.  Nonstatutory Stock Options may be granted to Service
            -----------
Providers.  Incentive Stock Options may be granted only to Employees.

        6.  Limitations.
            -----------

            (a)  Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

            (b)  Neither the Plan nor any Option shall confer upon an Optionee
any right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

            (c)  The following limitations shall apply to grants of Options:

                        (i)  No Service Provider shall be granted, in any fiscal
year of the Company, Options to purchase more than [________] Shares.

                        (ii)  In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional
[________] Shares, which shall not count against the limit set forth in
subsection (i) above.

                        (iii)  The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 12.

                        (iv)  If an Option is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 12), the

                                      -5-
<PAGE>

cancelled Option will be counted against the limits set forth in subsections (i)
and (ii) above. For this purpose, if the exercise price of an Option is reduced,
the transaction will be treated as a cancellation of the Option and the grant of
a new Option

        7.  Term of Plan. Subject to Section 18 of the Plan, the Plan shall
            ------------
become effective upon its adoption by the Board. It shall continue in effect for
a term of ten (10) years unless terminated earlier under Section 14 of the Plan.

        8.  Term of Option. The term of each Option shall be stated in the
            --------------
Option Agreement. In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided in
the Option Agreement. Moreover, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Incentive Stock Option is granted, owns
stock representing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Incentive Stock Option shall be five (5) years from the date of
grant or such shorter term as may be provided in the Option Agreement.

        9.  Option Exercise Price and Consideration.
            ---------------------------------------

            (a)  Exercise Price. The per share exercise price for the Shares to
                 --------------
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                        (i)  In the case of an Incentive Stock Option

                             (A)  granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                             (B)  granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

                        (ii)  In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Administrator. In the case
of a Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                        (iii)  Notwithstanding the foregoing, Options may be
granted with a per Share exercise price of less than 100% of the Fair Market
Value per Share on the date of grant pursuant to a merger or other corporate
transaction.

            (b)  Waiting Period and Exercise Dates. At the time an Option is
                 ---------------------------------
granted the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

                                      -6-
<PAGE>

            (c)  Form of Consideration. The Administrator shall determine the
                 ---------------------
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

                        (i)  cash;

                        (ii)  check;

                        (iii)  promissory note;

                        (iv)  other Shares, provided Shares acquired from the
Company (A) have been owned by the Optionee for more than six (6) months on the
date of surrender, and (B) have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Shares as to which said Option
shall be exercised;

                        (v)  consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;

                        (vi)  a reduction in the amount of any Company liability
to the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                        (vii)  any combination of the foregoing methods of
payment; or

                        (viii)  such other consideration and method of payment
for the issuance of Shares to the extent permitted by Applicable Laws.

        10.  Exercise of Option.
             ------------------

             (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
                  -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a

                                      -7-
<PAGE>

dividend or other right for which the record date is prior to the date the
Shares are issued, except as provided in Section 12 of the Plan.

                Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

             (b)  Termination of Relationship as a Service Provider. If an
                  -------------------------------------------------
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

             (c)  Disability of Optionee. If an Optionee ceases to be a
                  ----------------------
Service Provider as a result of the Optionee's Disability, the Optionee may
exercise his or her Option within such period of time as is specified in the
Option Agreement to the extent the Option is vested on the date of termination
(but in no event later than the expiration of the term of such Option as set
forth in the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

             (d)  Death of Optionee. If an Optionee dies while a Service
                  -----------------
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

        11.  Non-Transferability of Options.  Unless determined otherwise by the
             ------------------------------
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.  If the Administrator makes an Option
transferable,

                                      -8-
<PAGE>

such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
             ------------------------------------------------------------------
Asset Sale.
----------

             (a)  Changes in Capitalization. Subject to any required action by
                  -------------------------
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, the number of shares that may be added annually to the
shares reserved under the Plan (pursuant to Section 3(a)(i)), as well as the
price per share of Common Stock covered by each such outstanding Option, shall
be proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an
Option.

             (b)  Dissolution or Liquidation. In the event of the proposed
                  --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

             (c)  Merger or Asset Sale. In the event of a merger of the Company
                  --------------------
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option shall be assumed or an equivalent option
or right substituted by the successor corporation or a Parent or Subsidiary of
the successor corporation. In the event that the successor corporation refuses
to assume or substitute for the Option, the Optionee shall fully vest in and
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period. For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option immediately prior to the
merger or sale of

                                      -9-
<PAGE>

assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

        13.  Date of Grant. The date of grant of an Option shall be, for all
             -------------
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

        14.  Amendment and Termination of the Plan.
             -------------------------------------

             (a)  Amendment and Termination. The Board may at any time amend,
                  -------------------------
alter, suspend or terminate the Plan.

             (b)  Shareholder Approval. The Company shall obtain shareholder
                  --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

             (c)  Effect of Amendment or Termination. No amendment, alteration,
                  ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

        15.  Conditions Upon Issuance of Shares.
             ----------------------------------

             (a)  Legal Compliance. Shares shall not be issued pursuant to the
                  ----------------
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

             (b)  Investment Representations. As a condition to the exercise of
                  --------------------------
an Option, the Company may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

        16.  Inability to Obtain Authority. The inability of the Company to
             -----------------------------
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any

                                      -10-
<PAGE>

liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

        17.  Reservation of Shares. The Company, during the term of this Plan,
             ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        18.  Shareholder Approval. The Plan shall be subject to approval by the
             --------------------
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

II.  AGREEMENT
     ---------
     A.  Grant of Option.
         ---------------

          The Plan Administrator of the Company hereby grants to the Optionee
named in the Notice of Grant attached as Part I of this Agreement (the
"Optionee") an option (the "Option") to purchase the number of Shares, as set
forth in the Notice of Grant, at the exercise price per share set forth in the
Notice of Grant (the "Exercise Price"), subject to the terms and conditions of
the Plan, which is incorporated herein by reference.  Subject to Section 14(c)
of the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

          If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code.  However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

     B.  Exercise of Option.
         -------------------

         (a)  Right to Exercise. This Option is exercisable during its term in
              -----------------
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

         (b)  Method of Exercise. This Option is exercisable by delivery of an
              ------------------
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
                                         ---------
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed Exercise Notice accompanied by such aggregate Exercise
Price.

              No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

                                      -2-

         -----------------
any of the following, or a combination thereof, at the election of the Optionee:

         2.  check; or

         3.  consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

         4.  surrender of other Shares provided Shares acquired from the
Company, (i) have been owned by the Optionee for more than six (6) months on the
date of surrender, and (ii) have a Fair Market Value on the date of surrender
equal to the aggregate Exercise Price of the Exercised Shares.

     D.  Non-Transferability of Option. This Option may not be transferred in
         -----------------------------
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

     E.  Term of Option. This Option may be exercised only within the term set
         --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

     F.  Tax Obligations.
         ---------------

         1.  Withholding Taxes. Optionee agrees to make appropriate arrangements
             -----------------
with the Company (or the Parent or Subsidiary employing or retaining Optionee)
for the satisfaction of all Federal, state, local and foreign income and
employment tax withholding requirements applicable to the Option exercise.
Optionee acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

         2.  Notice of Disqualifying Disposition of ISO Shares. If the Option
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

     G.  Entire Agreement; Governing Law.  The Plan is incorporated herein by
         -------------------------------
reference.  The Plan and this Option Agreement constitute the entire agreement
of the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee.  This agreement is governed by the internal substantive laws, but not
the choice of law rules, of California.

HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS

OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE
PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

     By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
