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 purchase.





(b)    Cause.    Cause shall mean Optionees (i) willful act of personal dishonesty, gross misconduct, fraud or misrepresentation, taken by Optionee in

occurrence of any of the following events:

outstanding immediately after such merger, consolidation or sale;

(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 Option
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

base salary and any non-discretionary and objective standard incentive payments or bonus awards, but excluding facilities, fringe benefits and prerequisites included in Subsection 7(d)(iii)below);





(ii)    a reduction of the scope or nature of Optionees duties and/or responsibilities, it being understood
that the fact alone that Optionees duties and/or responsibilities are conducted at the Company level following a Change of Control, rather than at the combined entity level, shall constitute a Good Reason Event;





(iii)    a substantial reduction, without good business reasons, of the facilities, fringe benefits or perquisites
available to Optionee immediately prior to such reduction (good business reasons include reductions to make such facilities, fringe benefits or perquisites consistent with the practice of the acquiring company);





(iv)    the relocation of Optionees primary workplace to a location more than fifty (50) miles away from
his/her workplace in effect immediately prior to such relocation; or





(v)    the failure of
the Company to obtain the express assumption of this Option Agreement, including the terms of Section 6 and this Section 7, by an acquiring corporation.





8.    Tax Consequences.





Set forth
below is a brief summary as of the date of this Option Agreement of some of the federal tax consequences of exercise of the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO
CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.





(a)    Exercise of the Option.    Upon the exercise of the Option, Optionee will recognize 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 the aggregate Exercise Price. If Optionee is an Employee or a former Employee, the Company will be required to withhold from Optionees 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.





(b)    Disposition of Shares.    If Shares are held for at least one year, any gain realized on disposition of such Shares
will be treated as long-term capital gain for federal income tax purposes.





9.    Entire
Agreement; Governing Law.





The Plan is incorporated herein by reference. The Plan and this Option Agreement,
including the exhibits hereto, 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 Optionees interest except by means of a writing signed by the Company and Optionee. This Option Agreement is governed by the internal substantive laws, but not the choice of law rules, of
California.





10.    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 OPTION 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.
