1.    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 15(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).





2.    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 Stock 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.

implemented by the Company in connection with the Plan; or





(d)  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.





4.    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.





5.    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.

of such Change of Control.





(ii)  Acceleration following a Buy-Side
Event.    Notwithstanding any vesting provisions to the contrary, upon a Good Reason Event following a Buy-Side Event during the term of that certain Employment Agreement by and between the Company and Optionee dated as of

7.    Definitions.    For purposes of this
Option Agreement, the following terms shall have the meanings set forth below:





(a)  Buy-Side
Event.    Buy-Side Event shall mean the (i) Companys acquisition, directly or indirectly, of securities of another corporation or entity representing more than fifty percent (50%) of the total voting power
represented by such corporation or entitys then outstanding voting securities or (ii) a merger or consolidation of another corporation or entity with the Company, or the Companys purchase of all or substantially all the assets of another
corporation or entity, a result of which merger, consolidation or purchase, the voting securities of such corporation or entity outstanding immediately prior thereto do not continue to represent (either by remaining outstanding or by being converted
into voting securities of the Company) more than fifty percent (50%) of the total voting power represented by the voting securities of such corporation or entity or surviving entity outstanding immediately after such merger, consolidation or sale.





(b)  Cause.    Cause shall mean Optionees:  (i) willful act of
personal dishonesty, gross misconduct, fraud or misrepresentation, taken by Optionee in connection with his responsibilities as an employee of the Company, that is seriously injurious to the Company; (ii) conviction of or plea of guilty or nolo
contendre to a felony; or (iii) willful and continued failure to substantially perform his principal duties and/or obligations of employment (other than such failure resulting from incapacity due to bonafide physical or mental illness), which
failure is not remedied within a period of forty-five (45) days after written notice from the Company, specifically identifying the manner in which the Company believes that Optionee has not substantially performed his duties and/or obligations. No
act or failure to act shall be considered willful unless done or omitted to be done in bad faith and without reasonable belief that the act or omission was in or not opposed to the best interests of the Company.





(c)  Change of Control.    Change of Control shall mean the occurrence of any of the following events:





(i)  the acquisition by any person (as such term is used in Sections 13(d) and 14(d) of the Exchange Act)
(other than the Company or a person that directly or indirectly controls, is controlled by, or is under common control with, the Company) of the beneficial ownership (as defined in Rule 13d3 under the Exchange Act), directly or
indirectly, of securities of the Company representing more than fifty percent (50%) of the total voting power represented by the Companys then outstanding voting securities; or





(ii)  a merger or consolidation of the Company with any other corporation, or the sale of all or substantially all the assets of the Company, a result of which merger,
consolidation or sale, the voting securities of the Company outstanding immediately prior thereto do not continue to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity, including the
parent corporation of such surviving entity) more than fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger, consolidation or sale; or





(iii)  the approval of a plan of complete liquidation or dissolution of the Company; or

---




(iv)  a change in the composition of the Board occurring within a 12month
period, as a result of which fewer than a majority of the directors are Incumbent Directors. Incumbent Directors shall mean directors who either (A) are members of the Board as of the date of this Agreement, or (B) are elected, or
nominated for election, to the Board with the affirmative votes of at least a majority of directors whose election was neither in connection with any transactions described in subsections (i) or (ii), nor in connection with an actual or threatened
proxy contest relating to the election of directors to the Board.





(d)  Good Reason
Event.    Good Reason Event shall mean if following the Companys acquisition of another corporation or entity, the Board takes any of the following Actions, without Optionees written
consent and without Cause:





(i)  a reduction of fifteen percent (15%) or more of Optionees compensation
(including base salary and any non-discretionary and objective standard incentive payments or bonus awards, but excluding facilities, fringe benefits and perquisites included in subsection (iii) below) in effect immediately prior to such reduction;





(ii)  a reduction of Optionees duties and/or responsibilities; or





(iii)  a substantial reduction, without good business reasons, of the facilities, fringe benefits and perquisites available to Optionee prior
to such Action; and





(iv)  within thirty (30) days after any such Action, Optionee provides written notice to the
Board describing in reasonable detail the Action; and





(v)  the Board does not cure such Action within thirty (30)
days after receipt of Optionees notice.





8.    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.





9.    Exercising the Option.





(a)  Nonstatutory Stock Option.    The Optionee may incur regular federal income tax liability upon exercise of a 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.




5




---




(b)  Incentive Stock Option.    If this Option qualifies
as an ISO, the Optionee will have no regular federal income tax liability upon its exercise, although the excess, if any, of the Fair Market Value of the Exercised Shares on the date of exercise over their aggregate Exercise Price will be treated as
an adjustment to alternative minimum taxable income for federal tax purposes and may subject the Optionee to alternative minimum tax in the year of exercise. In the event that the Optionee ceases to be an Employee but remains a Service Provider, any
Incentive Stock Option of the Optionee that remains unexercised shall cease to qualify as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option on the date three (3) months and one (1) day following such
change of status.





(c)  Disposition of Shares.





(i)  NSO.    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.





(ii)  ISO.    If the Optionee holds ISO
Shares for at least one year after exercise and two years after the grant date, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. If the Optionee disposes of ISO Shares within
one year after exercise or two years after the grant date, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and the aggregate Exercise Price, or (B) the difference between the sale price of such Shares and the aggregate Exercise Price. Any additional gain will be taxed as capital
gain, short-term or long-term depending on the period that the ISO Shares were held.





(iii)  Notice of
Disqualifying Disposition of ISO Shares.    If the Optionee sells or otherwise disposes of any of the Shares acquired pursuant to an ISO on or before the later of (i) two years after the grant date, or (ii) one year after the
exercise date, the Optionee shall immediately notify the Company in writing of such disposition. The Optionee agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized from such early
disposition of ISO Shares by payment in cash or out of the current earnings paid to the Optionee.





10.    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.





11.    No Guarantee of Continued Service.
