(a) Procedure.
 (i) Multiple Administrative Bodies.  The Plan may
be administered by different Committees with respect to different
groups of Service Providers.
 (ii) Rule 16b-3.  To the extent desirable to qualify

Committee, which committee shall be constituted to satisfy Applicable
Laws.
(b) Powers of the Administrator.  Subject to the provi-

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 of the

 (ii) to select the Service Providers to whom Options
may be granted hereunder;
 (iii) to determine whether and to what extent Options
are granted hereunder;
 (iv) to determine the number of shares of Common

Plan;
 (vi) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award 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;
 (vii) to reduce the exercise price of any Option to
the then current Fair Market Value if the Fair Market Value of the
Common Stock covered by such Option shall have declined since the date
the Option was granted;
 (viii) to institute an Option Exchange Program;
 (ix) to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;
 (x) 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 qualifying for
preferred tax treatment under foreign tax laws;

Section 14(b) 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;
 (xii) to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option or
previously granted by the Administrator;
 (xiii) 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 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; and
 (xiv) 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.  Options may be granted to Service Providers
other than Officers (except as set forth herein).  Officers shall not
be eligible to receive Options under this Plan; provided, however, that
Options may be granted to an Officer not previously employed by the
Company, as an inducement essential to the individual's entering into
an employment contract with the Company.
6. Limitation.  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.
7. Term of Plan.  The Plan shall become effective upon its
adoption by the Board.  It shall continue in effect for ten (10) years,
unless sooner terminated under Section 14 of the Plan.
8. Term of Option.  The term of each Option shall be stated 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.
(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 which
must be satisfied before the Option may be exercised.
(c) Form of Consideration.  The Administrator shall
determine the acceptable form of consideration for exercising an
Option, including the method of payment.  Such consideration may
consist entirely of:
 (i) cash;
 (ii) check;
 (iii) promissory note;
 (iv) other Shares which (A) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee
for more than six 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) such other consideration and method of payment
for the issuance of Shares to the extent permitted by Applicable Laws;
or
 (viii) any combination of the foregoing methods of
payment.
10. Exercise of Option.
(a) Procedure for Exercise; Rights as a Stockholder. 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 stockholder
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 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, but only within such period of time as is specified in the
Option Agreement, and only 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.
(e) Buyout Provisions.  The Administrator may at any time
offer to buy out for a payment in cash or Shares, an Option previously
granted based on such terms and conditions as the Administrator shall
establish and communicate to the Optionee at the time that such offer
is made.
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, 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 stockholders 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,
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 or right confers the
right to purchase or receive, for each Share of Optioned Stock,
immediately prior to the merger or sale of 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 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) 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 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.

"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

and conditions of the Plan and the terms and conditions of this Option
Agreement, the terms and conditions of the Plan shall prevail.
(b) Exercise of Option.
 (i) 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.
 (ii) 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 stock option administrator of 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.
(c) Method of Payment.  Payment of the aggregate Exercise
Price shall be by any of the following, or a combination thereof, at
the election of the Optionee:
 (i) cash;
 (ii) check;
 (iii) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with
the Plan; or
 (iv) surrender of other Shares which (i) in the case
of Shares acquired upon exercise of an option, 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.
 (v) with the Administrator's consent, delivery of
Optionee's promissory note (the "Note") in the form attached hereto as
Exhibit C, in the amount of the aggregate Exercise Price of the
Exercised Shares together with the execution and delivery by the
Optionee of the Security Agreement attached hereto as Exhibit B.  The

under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the
Security Agreement.
(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 Consequences.  Some of the federal tax
consequences relating to this Option, as of the date of this Option,
are set forth below.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  THE OPTIONEE SHOULD
CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE
SHARES.
 (i) Exercising the Option.  The Optionee may incur
regular federal income tax liability upon exercise of an NSO.  The
Optionee will be treated as having received compensation income
(taxable at ordinary income tax rates) equal to the excess, if any, of
the Fair Market Value of the Exercised Shares on the date of exercise
over their aggregate Exercise Price.  If the Optionee is an Employee or
a former Employee, the Company will be required to withhold from his or
her compensation or collect from Optionee and pay to the applicable
taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor
the exercise and refuse to deliver Shares if such withholding amounts
are not delivered at the time of exercise.
 (ii) Disposition of Shares.  If the Optionee holds
NSO Shares for at least one year, any gain realized on disposition of
the Shares will be treated as long-term capital gain for federal income
tax purposes.
(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.
(h) NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE
ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE
VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING
HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER).
OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH
HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED
ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY
PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE
COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE
PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

By Optionee's signature and the signature of the Company's
representative below, Optionee and the Company agree that this Option
is granted under and governed by the terms and conditions of the Plan
and this Option Agreement.  Optionee has reviewed the Plan and this
Option Agreement in their entirety, has had an opportunity to obtain
the advice of counsel prior to executing this Option Agreement and
fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all
decisions or interpretations of the Administrator upon any questions
relating to the Plan and Option Agreement.  Optionee further agrees to
