<U><B>STOCK OPTION AGREEMENT</B></U>



<P align="left" style="font-size: 10pt"><U><B>RECITALS</B></U>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.&nbsp;The Board has adopted the Plan for the purpose of retaining the services of selected
Employees, non-employee members of the Board and consultants and other independent advisors who
provide services to the Corporation (or any Parent or Subsidiary).


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.&nbsp;Optionee is to render valuable services to the Corporation (or a Parent or Subsidiary), and
this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in
connection with the Corporation&#146;s grant of an option to Optionee.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.&nbsp;All capitalized terms in this Agreement shall have the meaning assigned to them in the
attached Appendix.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>NOW, THEREFORE</B>, it is hereby agreed as follows:



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <U><B>Grant of Option</B></U>. The Corporation hereby grants to Optionee, as of the
Grant Date, an option to purchase up to the number of Option Shares specified in the Grant Notice.
The Option Shares shall be purchasable from time to time during the option term specified in
Paragraph&nbsp;2 at the Exercise Price.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <U><B>Option Term</B></U>. This option shall have a maximum term of ten (10)&nbsp;years
measured from the Grant Date and shall accordingly expire at the close of business on the
Expiration Date, unless sooner terminated in accordance with Paragraph&nbsp;5 or 6.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <U><B>Limited Transferability</B></U>.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;Except as provided in Section&nbsp;3(b), this option shall be neither transferable nor
assignable by Optionee other than by will or the laws of inheritance following Optionee&#146;s death and
may be exercised, during Optionee&#146;s lifetime, only by Optionee. However, Optionee may designate
one or more persons as the beneficiary or beneficiaries of this option, and this option shall, in
accordance with such designation, automatically be transferred to such beneficiary or beneficiaries
upon Optionee&#146;s death while holding this option. Such beneficiary or beneficiaries shall take the
transferred option subject to all the terms and conditions of this Agreement, including (without
limitation) the limited time period during which this option may, pursuant to Paragraph&nbsp;5, be
exercised following Optionee&#146;s death.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;If this option is designated a Non-Statutory Option in the Grant Notice, then this option
may be assigned in whole or in part during Optionee&#146;s lifetime to one or more members of Optionee&#146;s
family or to a trust established for the exclusive benefit of one or more such family members, to
the extent such assignment is in connection with Optionee&#146;s estate plan, or to Optionee&#146;s former
spouse pursuant to a domestic relations order. The assigned portion shall be exercisable only by
the person or persons who acquire a proprietary interest in the option pursuant to such assignment.
The terms applicable to the assigned portion shall be the same as those in effect for this option
immediately prior to such assignment.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <U><B>Dates of Exercise</B></U>. This option shall become exercisable for the Option
Shares in one or more installments as specified in the Grant Notice. As the option becomes
exercisable for such installments, those installments shall accumulate, and the option shall remain
exercisable for the accumulated installments until the Expiration Date or sooner termination of the
option term under Paragraph&nbsp;5 or 6.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <U><B>Cessation of Service</B></U>. The option term specified in Paragraph&nbsp;2 shall
terminate (and this option shall cease to be outstanding) prior to the Expiration Date should any
of the following provisions become applicable:



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;Should Optionee cease to remain in Service for any reason (other than death, Permanent
Disability or Misconduct) while holding this option, then Optionee shall have a period of three (3)
months (commencing with the date of such cessation of Service) during which to exercise this
option, but in no event shall this option be exercisable at any time after the Expiration Date.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;Should Optionee die while holding this option, then the personal representative of
Optionee&#146;s estate or the person or persons to whom the option is transferred pursuant to Optionee&#146;s
will or the laws of inheritance shall have the right to exercise this option. However, if Optionee
has designated one or more beneficiaries of this option, then those persons shall have the

<DIV style="font-family: 'Times New Roman',Times,serif">
<P align="left" style="font-size: 10pt">exclusive right to exercise this option following Optionee&#146;s death. Any such right to
exercise this option shall lapse, and this option shall cease to be outstanding, upon the
<U>earlier</U> of (i)&nbsp;the expiration of the twelve (12)-month period measured from the date of
Optionee&#146;s death or (ii)&nbsp;the Expiration Date.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Should Optionee cease Service by reason of Permanent Disability while holding this option,
then Optionee shall have a period of twelve (12)&nbsp;months (commencing with the date of such cessation
of Service) during which to exercise this option. In no event shall this option be exercisable at
any time after the Expiration Date.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;During the limited period of post-Service exercisability, this option may not be exercised
in the aggregate for more than the number of Option Shares for which the option is exercisable at
the time of Optionee&#146;s cessation of Service. Upon the expiration of such limited exercise period
or (if earlier) upon the Expiration Date, this option shall terminate and cease to be outstanding
for any exercisable Option Shares for which the option has not been exercised. However, this
option shall, immediately upon Optionee&#146;s cessation of Service for any reason, terminate and cease
to be outstanding with respect to any Option Shares for which this option is not otherwise at that
time exercisable.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;Should Optionee&#146;s Service be terminated for Misconduct or should Optionee otherwise engage
in any Misconduct while this option is outstanding, then this option shall terminate immediately
and cease to remain outstanding.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <U><B>Special Acceleration of Option</B></U>.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;This option, to the extent outstanding at the time of a Corporate Transaction but not
otherwise fully exercisable, shall automatically accelerate so that this option shall, immediately
prior to the effective date of such Corporate Transaction, become exercisable for all of the Option

Shares at the time subject to this option and may be exercised for any or all of those Option
Shares as fully vested shares of Common Stock. However, this option shall <B>not </B>become exercisable
on such an accelerated basis, if and to the extent: (i)&nbsp;this option is, in connection with the
Corporate Transaction, to be assumed by the successor corporation (or parent thereof) or replaced
with a comparable option to purchase shares of the capital stock of the successor corporation (or
parent thereof) or (ii)&nbsp;this option is to be replaced with a cash incentive program of the
successor corporation which preserves the spread existing at the time of the Corporate Transaction
on any Option Shares for which this option is not otherwise at that time exercisable (the excess of
the Fair Market Value of those Option Shares over the aggregate Exercise Price payable for such
shares) and provides for subsequent payout in accordance with the same option exercise/vesting
schedule for those Option Shares set forth in the Grant Notice. The determination of comparability
under clause (i)&nbsp;above shall be made by the Plan Administrator, and its determination shall be
final, binding and conclusive.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;Immediately following the Corporate Transaction, this option shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or parent thereof) in
connection with the Corporate Transaction.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;If this option is assumed in connection with a Corporate Transaction, then this option
shall be appropriately adjusted, immediately after such Corporate Transaction, as determined by the
Plan Administrator in its sole discretion in order to prevent diminution or enlargement of benefits
or potential benefits intended to be made under this option.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;This Agreement shall not in any way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <U><B>Adjustment in Option Shares</B></U>. Should any change be made to the Common
Stock by reason of any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a class without the
Corporation&#146;s receipt of consideration, appropriate adjustments shall be made to (i)&nbsp;the total
number and/or class of securities subject to this option and (ii)&nbsp;the Exercise Price in order to
reflect such change and thereby preclude a dilution or enlargement of benefits hereunder.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <U><B>Shareholder Rights</B></U>. The holder of this option shall not have any
shareholder rights with respect to the Option Shares until such person shall have exercised the
option, paid the Exercise Price and become a holder of record of the purchased shares.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <U><B>Manner of Exercising Option</B></U>.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;In order to exercise this option with respect to all or any part of the Option Shares for
which this option is at the time exercisable, Optionee (or any other person or persons exercising
the option) must take the following actions:

<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Execute and deliver to the Corporation a Notice of Exercise for the Option
Shares for which the option is exercised.



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Pay the aggregate Exercise Price for the purchased shares in one or more of
the following forms:



<P align="left" style="margin-left:6%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) cash or check made payable to the Corporation;



<P align="left" style="margin-left:6%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) shares of Common Stock held by Optionee (or any other person or
persons exercising the option) for the requisite period necessary to avoid a
charge to the Corporation&#146;s earnings for financial reporting purposes and
valued at Fair Market Value on the Exercise Date; or



<P align="left" style="margin-left:6%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) through a special sale and remittance procedure pursuant to which
Optionee (or any other person or persons exercising the option) shall
concurrently provide irrevocable instructions (i)&nbsp;to a Corporation-designated
brokerage firm to effect the immediate sale of the purchased shares and remit
to the Corporation, out of the sale proceeds available on the settlement date,
sufficient funds to cover the aggregate Exercise Price payable for the
purchased shares plus all applicable Federal, state and local income and
employment taxes required to be withheld by the Corporation by reason of such
exercise and (ii)&nbsp;to the Corporation to deliver the certificates for the
purchased shares directly to such brokerage firm in order to complete the sale.



<P align="left" style="margin-left:6%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except to the extent the sale and remittance procedure is utilized in
connection with the option exercise, payment of the Exercise Price must
accompany the Notice of Exercise delivered to the Corporation in connection
with the option exercise.



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Furnish to the Corporation appropriate documentation that the person or
persons exercising the option (if other than Optionee) have the right to exercise this
option.



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Make appropriate arrangements with the Corporation (or Parent or Subsidiary
employing or retaining Optionee) for the satisfaction of all Federal, state and local
income and employment tax withholding requirements applicable to the option exercise.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;As soon as practical after the Exercise Date, the Corporation shall issue to or on behalf
of Optionee (or any other person or persons exercising this option) a certificate for the purchased
Option Shares (which may be in book entry form), with the appropriate legends, if any, affixed
thereto.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;In no event may this option be exercised for any fractional shares.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <U><B>Compliance with Laws and Regulations</B></U>.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;The exercise of this option and the issuance of the Option Shares upon such exercise shall
be subject to compliance by the Corporation and Optionee with all applicable requirements of law
relating thereto and with all applicable regulations of any stock exchange (or the Nasdaq National
Market, if applicable) on which the Common Stock may be listed for trading at the time of such
exercise and issuance.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The inability of the Corporation to obtain approval from any regulatory body having
authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common
Stock pursuant to this option shall relieve the Corporation of any liability with respect to the
non-issuance or sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such approvals.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <U><B>Successors and Assigns</B></U>. Except to the extent otherwise provided in
Paragraphs 3 and 6, the provisions of this Agreement shall inure to the benefit of, and be binding
upon, the Corporation and its successors and assigns and Optionee, Optionee&#146;s assigns, the legal
representatives, heirs and legatees of Optionee&#146;s estate and any beneficiaries of this option
designated by Optionee.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. <U><B>Notices</B></U>. Any notice required to be given or delivered to the

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. <U><B>Construction</B></U>. This Agreement and the option evidenced hereby are made
and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the
Plan. All decisions of the Plan Administrator with respect to any question or issue arising under
the Plan or this Agreement shall be conclusive and binding on all persons having an interest in
this option.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. <U><B>Governing Law</B></U>. The interpretation, performance and enforcement of this
Agreement shall be governed by the laws of the State of California without resort to that State&#146;s
conflict-of-laws rules.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. <U><B>Excess Shares</B></U>. If the Option Shares covered by this Agreement exceed,
as of the Grant Date, the number of shares of Common Stock which may without shareholder approval
be issued under the Plan, then this option shall be void with respect to those excess shares,
unless shareholder approval of an amendment sufficiently increasing the number of shares of Common
Stock issuable under the Plan is obtained in accordance with the provisions of the Plan.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. <U><B>Tax Obligations.</B></U>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;Optionee agrees to make appropriate arrangements with the Corporation (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 exercise of this
option. Optionee acknowledges and agrees that the Corporation may refuse to honor the exercise and
refuse to deliver the Option Shares if such withholding amounts are not delivered at the time of
exercise.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;In the event this option is designated an Incentive Option in the Grant Notice, and if
Optionee sells or otherwise disposes of any of the Option Shares acquired pursuant to the Incentive
Option on or before the later of (1)&nbsp;the date two years after the Grant Date, or (2)&nbsp;the date one
year after the date of exercise, Optionee shall immediately notify the Corporation in writing of
such disposition. Optionee agrees that Optionee may be subject to income tax withholding by the
Corporation (or the Parent or Subsidiary employing or retaining Optionee) on the compensation
income recognized by Optionee.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. <U><B>Additional Terms Applicable to an Incentive Option</B></U>. In the event this
option is designated an Incentive Option in the Grant Notice, the following terms and conditions
shall also apply to the grant:



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;This option shall cease to qualify for favorable tax treatment as an Incentive Option if
(and to the extent) this option is exercised for one or more Option Shares: (A)&nbsp;more than three (3)
months after the date Optionee ceases to be an Employee for any reason other than death or
Permanent Disability or (B)&nbsp;more than twelve (12)&nbsp;months after the date Optionee ceases to be an
Employee by reason of Permanent Disability.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;No installment under this option shall qualify for favorable tax treatment as an Incentive
Option if (and to the extent) the aggregate Fair Market Value (determined at the Grant Date) of the
Common Stock for which such installment first becomes exercisable hereunder would, when added to
the aggregate value (determined as of the respective date or dates of grant) of the Common Stock or
other securities for which this option or any other Incentive Options granted to Optionee prior to
the Grant Date (whether under the Plan or any other option plan of the Corporation or any Parent or
Subsidiary) first become exercisable during the same calendar year, exceed One Hundred Thousand
Dollars ($100,000) in the aggregate. Should such One Hundred Thousand Dollar ($100,000) limitation
be exceeded in any calendar year, this option shall nevertheless become exercisable for the excess
shares in such calendar year as a Non-Statutory Option.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Should the exercisability of this option be accelerated upon a Corporate Transaction, then
this option shall qualify for favorable tax treatment as an Incentive Option only to the extent the
aggregate Fair Market Value (determined at the Grant Date) of the Common Stock for which this
option first becomes exercisable in the calendar year in which the Corporate Transaction occurs
does not, when added to the aggregate value (determined as of the respective date or dates of
grant) of the Common Stock or other securities for which this option or one or more other Incentive
Options granted to Optionee prior to the Grant Date (whether under the Plan or any other option
plan of the Corporation or any Parent or Subsidiary) first become exercisable during the same
calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. Should the
applicable One Hundred Thousand Dollar ($100,000) limitation be exceeded in the calendar year of
such Corporate Transaction, the option may nevertheless be exercised for the excess shares in such
calendar year as a Non-Statutory Option.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;Should Optionee hold, in addition to this option, one or more other options to purchase
Common Stock which become exercisable for the first time in the same calendar year as this option,
then the foregoing limitations on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. <U><B>Leave of Absence</B></U>. The following provisions shall apply upon Optionee&#146;s
commencement of an authorized leave of absence:



<P align="center" style="font-size: 10pt">5

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;The exercise schedule in effect under the Grant Notice shall be frozen as of the first day
of the authorized leave, and this option shall not become exercisable for any additional
installments of the Option Shares during the period Optionee remains on such leave.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;Should Optionee resume active Employee status within sixty (60)&nbsp;days after the start date
of the authorized leave, Optionee shall, for purposes of the exercise schedule set forth in the
Grant Notice, receive Service credit for the entire period of such leave. If Optionee does not
resume active Employee status within such sixty (60)-day period, then no Service credit shall be
given for the period of such leave.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;If the option is designated as an Incentive Option in the Grant Notice, then the following
additional provision shall apply:



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If the leave of absence continues for more than ninety (90)&nbsp;days, then this
option shall automatically convert to a Non-Statutory Option under the Federal tax
laws at the end of the three (3)-month period measured from the ninety-first (91st)
day of such leave, unless Optionee&#146;s reemployment rights are guaranteed by statute or
by written agreement. Following any such conversion of the option, all subsequent
exercises of such option, whether effected before or after Optionee&#146;s return to active
Employee status, shall result in an immediate taxable event, and the Corporation shall
be required to collect from Optionee the Federal, state and local income and
employment withholding taxes applicable to such exercise.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;In no event shall this option become exercisable for any additional Option Shares or
otherwise remain outstanding if Optionee does not resume Employee status prior to the Expiration
Date of the option term.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. <B>Entire Agreement</B>. The Plan is incorporated herein by reference. The Plan and
this 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 Corporation and
Optionee with respect to the subject matter hereof, and may not be modified adversely to Optionee&#146;s
interest except by means of a writing signed by the Corporation and Optionee.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20. <B>No Guarantee of Continued Service</B>. Optionee acknowledges and agrees that the
vesting of Option Shares pursuant to the vesting schedule in the Grant Notice is earned only by
Optionee continuing to provide Service at the will of the Corporation (or the Parent or Subsidiary
employing or retaining Optionee) and not through the act of being hired, being granted this option
or acquiring the Option Shares hereunder. Optionee further acknowledges and agrees that this
Agreement, the transactions contemplated hereunder and the vesting schedule set forth in the Grant
Notice do not constitute an express or implied promise of continued engagement to provide Service
for the vesting period, for any period, or at all, and shall not interfere in any way with
Optionee&#146;s right or the Corporation&#146;s right (or the right of the Parent or Subsidiary employing or
retaining Optionee) to terminate Optionee&#146;s Service at any time, with or without cause.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I hereby notify Network Appliance, Inc. (the &#147;Corporation&#148;) that I elect to purchase
&#95;&#95;&#95;&#95;&#95;&#95;shares of the Corporation&#146;s Common Stock (the &#147;Purchased Shares&#148;) at the option
exercise price of $&#95;&#95;&#95;&#95;&#95;&#95;per share (the &#147;Exercise Price&#148;) pursuant to that certain option (the &#147;Option&#148;)
granted to me under the Corporation&#146;s 1999 Stock Option Plan (the &#147;Plan&#148;) and the Stock Option
Agreement dated &#95;&#95;&#95;&#95;&#95;&#95;, &#95;&#95;&#95;&#95;&#95;&#95;(the &#147;Option Agreement&#148;).



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Concurrently with the delivery of this Exercise Notice to the Corporation, I shall hereby pay
to the Corporation the Exercise Price for the Purchased Shares in accordance with the provisions of
my agreement with the Corporation (or other documents) evidencing the Option together with any
applicable withholding taxes resulting from such purchase and shall deliver whatever additional
documents may be required by such agreement as a condition for exercise. Alternatively, I may
utilize the special broker-dealer sale and remittance procedure specified in my agreement to effect
payment of the Exercise Price.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I understand that I may suffer adverse tax consequences as a result of my purchase or
disposition of the Purchased Shares. I represent that I have consulted with any tax consultants I
deems advisable in connection with the purchase or disposition of the Purchased Shares and that I
am not relying on the Corporation for any tax advice.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Plan and Option Agreement are incorporated herein by reference. This Notice of Exercise,
the Plan and the 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 Corporation and me with respect to the subject matter hereof, and may not be modified adversely
to my interest except by means of a writing signed by the Corporation and me. This Notice of
Exercise is governed by the internal substantive laws but not the choice of law rules, of
California.
