reacquired Common Stock. 
  
 If an Option should
expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares which were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan. In addition,
any Shares that are retained by the Company upon exercise of an Option in order to satisfy the exercise price of such Option, or any withholding taxes due with respect to such exercise, shall be treated as not issued and shall continue to be
available for issuance under the Plan. If Shares which were acquired upon exercise of an Option are subsequently repurchased by the Company, such Shares shall not in any event be returned to the Plan and shall not become available for future grant
under the Plan. 
  

 -ii- 








 4. Administration of and Grants of Options under the Plan. 
  
 (a) Administrator. Except as otherwise
required herein, the Plan shall be administered by the Board. 
  
 (b) Procedure for Grants. All grants of Options hereunder shall be automatic and nondiscretionary and shall be made strictly in accordance with the following provisions: 
  
 (i) No person shall have any discretion to select which
Outside Directors shall be granted Options or to determine the number of Shares to be covered by Options granted to Outside Directors. 
  
 (ii) Each person who becomes an Outside Director after the effective date of this Plan, as determined in accordance with Section 6 hereof,
shall be automatically granted an Option (the “First Option”) to purchase 10,000 (as adjusted for stock splits, stock dividends, reclassifications and like transactions) Shares on the date on which such person first becomes an
Outside Director, whether through election by the stockholders of the Company or appointment by the Board of Directors to fill a vacancy. 
  
 (iii) Each Outside Director (including an Outside Director who did not receive a First Option) shall be automatically granted an Option
(the “Annual Option”) to purchase 10,000 Shares (as adjusted for stock splits, stock dividends, reclassifications and like transactions) on the date of each annual meeting of the stockholders of the Company, provided that, on such
date, he or she shall have served on the Board for at least six (6) months prior to the first day of such fiscal year. 
  
 (iv) Each Outside Director who is serving as a Chairperson of a Committee of the Board as of the date of the annual meeting of the
stockholders of the Company, after the effective date of this Plan, shall be automatically granted an Option (the “Annual Committee Chairperson Option”) to purchase 2,500 Shares (as adjusted for stock splits, stock dividends,
reclassifications and like transactions) on the date of such annual meeting of the stockholders of the Company. 
  
 (v) Each Outside Director who is serving as a member of the Audit Committee of the Board (including the Chairperson) as of the date of the
annual meeting of the stockholders of the Company, after the effective date of this Plan, shall be automatically granted an Option (the “Annual Audit Committee Option”) to purchase 2,500 Shares (as adjusted for stock splits, stock
dividends, reclassifications and like transactions) on the date of such annual meeting of the stockholders of the Company. 
  
 (vi) Notwithstanding the provisions of subsections (ii), (iii), (iv), and (v) hereof, in the event that a grant would cause the number of
Shares subject to outstanding Options plus the number of Shares previously purchased upon exercise of Options to exceed the Pool, then each such automatic grant shall be for that number of Shares determined by dividing the total number of Shares
remaining available for grant by the number of Outside Directors receiving an Option on such date on the automatic grant date. Any further grants shall then be 

  

 -iii- 








 
deferred until such time, if any, as additional Shares become available for grant under the Plan through action of the stockholders to increase the number of
Shares which may be issued under the Plan or through cancellation or expiration of Options previously granted hereunder. 
  
 (vii) Notwithstanding the provisions of subsections (ii) and (iii) hereof, any grant of an Option made before the Company has obtained
stockholder approval of the Plan in accordance with Section 17 hereof shall be conditioned upon obtaining such stockholder approval of the Plan in accordance with Section 17 hereof. 
  
 (viii) The terms of each Option granted hereunder shall be as follows: 
  
 (1) each Option shall be exercisable only while the Outside
Director remains a Director of the Company, except as set forth in Section 9 hereof; 
  
 (2) the exercise price per Share of the Option shall be 100% of the fair market value per Share on the date of grant of the Option,
determined in accordance with Section 8 hereof; and 
  
 (3) the First Option, each Annual Option, each Annual Committee Chairperson Option and each Annual Audit Committee Option shall become vested and exercisable as to 1/24th of the Shares underlying the Option on the one month anniversary of
its date of grant and as to 1/24th of the Shares underlying the Option each month thereafter so that, subject to
Section 11 below, the Option shall be fully vested and exercisable on the second anniversary of its date of grant. 
  
 (c) Powers of the Board. Subject to the provisions and restrictions of the Plan, the Board shall have the authority, in its
discretion: (i) to determine, upon review of relevant information and in accordance with Section 8(b) of the Plan, the fair market value of the Common Stock; (ii) to determine the exercise price per Share of Options to be granted, which exercise
price shall be determined in accordance with Section 8 of the Plan; (iii) to interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations relating to the Plan; (v) to authorize any person to execute on behalf of the Company any
instrument required to effectuate the grant of an Option previously granted hereunder; and (vi) to make all other determinations deemed necessary or advisable for the administration of the Plan. 
  
 (d) Effect of Board’s Decision. All
decisions, determinations and interpretations of the Board shall be final and binding on all Optionees and any other holders of any Options granted under the Plan. 
  
 (e) Suspension or Termination of Option. If the Chief Executive Officer or his or her designee
reasonably believes that an Optionee has committed an act of misconduct, such officer may suspend the Optionee’s right to exercise any option pending a determination by the Board (excluding the Outside Director accused of such misconduct). If
the Board (excluding the Outside Director accused of such misconduct) determines an Optionee has committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation owed to the Company, breach of fiduciary duty or deliberate disregard
of the Company rules resulting in loss, damage or injury to the Company, or if an Optionee makes an unauthorized disclosure of any Company trade 

  

 -iv- 








 
secret or confidential information, engages in any conduct constituting unfair competition, induces any Company customer to breach a contract with the
Company or induces any principal for whom the Company acts as agent to terminate such agency relationship, neither the Optionee nor his or her estate shall be entitled to exercise any Option whatsoever. In making such determination, the Board of
Directors (excluding the Outside Director accused of such misconduct) shall act fairly and shall give the Optionee an opportunity to appear and present evidence on Optionee’s behalf at a hearing before the Board or a committee of the Board.

  
 5. Eligibility. Options may be granted only to
Outside Directors. All Options shall be automatically granted in accordance with the terms set forth in Section 4(b) above. An Outside Director who has been granted an Option may, if he or she is otherwise eligible, be granted an additional Option
or Options in accordance with such provisions. 
  
 The Plan shall not confer upon any Optionee any right with respect to continuation of service as a Director or nomination to serve as a Director, nor shall it interfere in any way with any rights which the Director or the Company may have
to terminate his or her directorship at any time. 
  
 6.
Term of Plan; Effective Date. The Plan shall become effective on the effectiveness of the registration statement under the Securities Act of 1933, as amended, relating to the Company’s initial public offering of securities. It
shall continue in effect for a term of ten (10) years unless sooner terminated under Section 13 of the Plan. 
  
 7. Term of Options. The term of each Option shall be ten (10) years from the date of grant thereof, unless an Option terminates sooner
pursuant to Section 9 below. 
  
 8. 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 100% of the Fair Market Value per Share on the date of grant of the Option. 
  
 (b) Form of Consideration. The consideration
to be paid for the Shares to be issued upon exercise of an Option shall consist entirely of cash, check, other Shares of Common Stock having a fair market value on the date of surrender equal to the aggregate exercise price of the Shares as to which
the Option shall be exercised (which, if acquired from the Company, shall have been held more than six months), delivery of a properly executed exercise notice together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect exercise of the Option and prompt delivery to the Company of the sale or loan proceeds required to pay the exercise price, or any combination of such methods of payment and/or any other consideration or method of
payment as shall be permitted under applicable corporate law. 
  
 9. Exercise of Option. 
  
 (a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable at such times as are set forth in Section 4(b) above; provided, 

  

 -v- 








 
however, that no Options shall be exercisable prior to stockholder approval of the Plan in accordance with Section 17 below has been obtained. 
  
 An Option may not be exercised for a fraction of a Share.

  
 An Option shall be deemed to be exercised
when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may consist of any consideration and method of payment allowable under Section 8(c) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such Shares, 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. A
share certificate for the number of Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the
stock certificate is issued, except as provided in Section 11 of the Plan. 
  
 Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be 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 Status as a Director. If an Outside Director ceases to serve as a Director, he or she may, but only within ninety (90) days after the date he or she ceases to be a Director of the Company, exercise his or her Option to
the extent that he or she was entitled to exercise it at the date of such termination. Notwithstanding the foregoing, in no event may the Option be exercised after its term set forth in Section 7 has expired. To the extent that such Outside Director
was not entitled to exercise an Option at the date of such termination, or does not exercise such Option (to the extent he or she was entitled to exercise) within the time specified herein, the Option shall terminate and the Shares underlying the
unexercised portion of the Option shall revert to the Pool. 
  
 (c) Disability of Optionee. Notwithstanding Section 9(b) above, in the event a Director is unable to continue his or her service as a Director with the Company as a result of his or her total and
permanent disability (as defined in Section 22(e)(3) of the Code), he or she may, but only within twelve (12) months from the date of such termination, exercise his or her Option to the extent he or she was entitled to exercise it at the date of
such termination. Notwithstanding the foregoing, in no event may the Option be exercised after its term set forth in Section 7 has expired. To the extent that he or she was not entitled to exercise the Option at the date of termination, or if he or
she does not exercise such Option (to the extent he or she was entitled to exercise) within the time specified above, the Option shall terminate and the Shares underlying the unexercised portion of the Option shall revert to the Pool. 
  
 (d) Death of Optionee. In the event of the
death of an Optionee (i) during the term of the Option who is, at the time of his or her death, a Director of the Company and who shall have been in Continuous Status as a Director since the date of grant of the Option, or (ii) 3 months after the
termination of Continuous Status as a Director, the Option may be exercised, at 

  

 -vi- 








 
any time within 12 months following the date of death, by the Optionee’s estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent of the right to exercise that had accrued at the date of death or the date of termination, as applicable. Notwithstanding the foregoing, in no event may the Option be exercised after its term set forth in
Section 7 has expired. To the extent that an Optionee was not entitled to exercise the Option at the date of death or termination or if he or she does not exercise such Option (to the extent he or she was entitled to exercise) within the time
specified above, the Option shall terminate and the Shares underlying the unexercised portion of the Option shall revert to the Plan. 
  
 10. Nontransferability of Options. The Option may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner
other than (a) by will or by the laws of descent or distribution; (b) pursuant to a qualified domestic relations order (as defined by the Code or the rules thereunder); (c) by gift to the Optionee’s Family; or (d) by gift or in exchange for an
interest in such entity to (i) a trust in which Optionee and/or Optionee’s Family have more than fifty percent of the beneficial interest, (ii) a foundation in which Optionee and/or Optionee’s Family control the management of assets, or
(iii) any other entity in which Optionee and/or Optionee’s Family own more than fifty percent of the voting interests. For purposes of this Section 10, Optionee’s “Family” shall include any child, stepchild, grandchild,
parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law; daughter-in-law, brother-in-law or sister-in-law, including adoptive relationships, and any person sharing the employee’s
household (other than a tenant or employee). The designation of a beneficiary by an Optionee does not constitute a transfer. An Option may be exercised during the lifetime of an Optionee only by the Optionee or a transferee permitted by this
Section. 
  
 11. Adjustments Upon Changes in Capitalization;
Corporate Transactions. 
  
 (a)
Adjustment. Subject to any required action by the stockholders of the Company, the number of Shares of Common Stock covered by each outstanding Option, the number of Shares of Common Stock set forth in Section 4(b) above, 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. 
  

 -vii- 








 (b) Corporate Transactions. In the event of a Corporate Transaction, each
outstanding Option shall be assumed or an equivalent option shall be substituted by the successor corporation or a Parent or Subsidiary of such successor corporation, unless the successor corporation does not agree to assume the outstanding Options
or to substitute equivalent options, in which case the Options shall terminate upon the consummation of the transaction; provided, however, that in the event of any transaction that qualifies as a Change of Control and notwithstanding
whether or not outstanding Options are assumed, substituted for or terminated in connection with the transaction, the vesting of each outstanding Option shall accelerate in full such that each Optionee shall have the right to exercise his or her
Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable, immediately prior to consummation of the transaction. 
  
 For purposes of this Section 11(b), an Option shall be considered assumed, without limitation, if, at the
time of issuance of the stock or other consideration upon such Corporate Transaction, each Optionee would be entitled to receive upon exercise of an Option the same number and kind of shares of stock or the same amount of property, cash or
securities as the Optionee would have been entitled to receive upon the occurrence of such transaction if the Optionee had been, immediately prior to such transaction, the holder of the number of Shares of Common Stock covered by the Option at such
time (after giving effect to any adjustments in the number of Shares covered by the Option as provided for in this Section 11); provided however that if such consideration received in the transaction was 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 exercise of the Option to be solely common stock of the successor corporation or its Parent equal to
the Fair Market Value of the per Share consideration received by holders of Common Stock in the transaction. 
  
 (c) Certain Distributions. In the event of any distribution to the Company’s stockholders of securities of any other
entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, appropriately adjust the price per Share of Common Stock covered by each
outstanding Option to reflect the effect of such distribution. 
  
 12. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date determined in accordance with Section 4(b) hereof. Notice of the determination shall be given to each Outside Director to whom
an Option is so granted within a reasonable time after the date of such grant. 
  
 13. Amendment and Termination of the Plan. 
  
 (a) Amendment and Termination. The Board may amend or terminate the Plan from time to time in such respects as the Board may
deem advisable; provided that, to the extent necessary and desirable to comply with Rule 16b-3 under the Exchange Act (or any other applicable law or regulation), the Company shall obtain approval of the stockholders of the Company to
Plan amendments to the extent and in the manner required by such law or regulation. Notwithstanding the foregoing, the provisions set forth in Section 4 of this Plan (and any other Sections of this Plan that affect the formula award terms required
to be specified in this 

  

 -viii- 








 
Plan by Rule 16b-3) shall not be amended more than once every six months, other than to comport with changes in the Code, the Employee Retirement Income
Security Act of 1974, as amended, or the rules thereunder. 
  
 (b) Effect of Amendment or Termination. Any such amendment or termination of the Plan that would impair the rights of any Optionee shall not affect Options already granted to such Optionee and such
Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company.

  
 14. Conditions Upon Issuance of Shares.
Notwithstanding any other provision of the Plan or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such
issuance or delivery would comply with the legal requirements relating to the administration of stock option plans under applicable U.S. state corporate laws, U.S. federal and applicable state securities laws, the Code, any stock exchange or Nasdaq
rules or regulations to which the Company may be subject and the applicable laws of any other country or jurisdiction where Options are granted under the Plan, as such laws, rules, regulations and requirements shall be in place from time to time
(the “Applicable Laws”). Such compliance shall be determined by the Company in consultation with its legal counsel. 
  
 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 by law.

  
 15. 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. 
  
 16. Option Agreement. Options shall be evidenced by written option agreements in such form as the Board shall approve. 
  
 17. Stockholder Approval. If required by the Applicable Laws,
continuance of the Plan shall be subject to approval by the stockholders of the Company. Such stockholder approval shall be obtained in the manner and to the degree required under the Applicable Laws.

not defined herein shall have the meanings ascribed to such terms in the Plan. In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Nonstatutory Stock Option Agreement, the terms and conditions
of the Plan shall prevail. 
  
 2. Exercise of
Option. 
  
 (a) Right to
Exercise. This Option is exercisable during its term in accordance with the Vesting/Exercise Schedule set out in the Notice of Stock Option Grant and the applicable provisions of the Plan and this Nonstatutory Stock Option Agreement. In the
event of Optionee’s death, disability or other termination of Optionee’s service as a Director, the exercisability of the Option is governed by the applicable provisions of the Plan and this Nonstatutory Stock 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 signed by the Optionee and shall be delivered
in person or by certified mail to the Secretary 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 all relevant provisions
of law and the requirements of any stock exchange or quotation service upon which the Shares are then listed. 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.

 (d) surrender of other Shares which (i) in the case of
Shares acquired directly or indirectly from the Company, have been owned by the Optionee for more than six (6) months on the date of surrender, and (ii) in any case which have a Fair Market Value on the date of surrender equal to the aggregate
Exercise Price of the Exercised Shares.

mother-in-law, father-in-law, son-in-law; daughter-in-law, brother-in-law or sister-in-law, including adoptive relationships, and any person sharing the employee’s household (other than a tenant or employee). The designation of a beneficiary by
an Optionee does not constitute a transfer. An Option may be exercised during the lifetime of an Optionee only by the Optionee or a transferee permitted by this Section 4 and Section 10 of the Plan. The terms of the Plan and this Nonstatutory Stock
Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.

during such term only in accordance with the Plan and the terms of this Nonstatutory Stock Option Agreement. 
  
 6. Tax Consequences. Set forth below is a brief summary of certain federal and California tax consequences relating to this Option under the
law in effect as of the date of grant. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT HIS OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

  
 (a) Exercising the Option.
Since this Option does not qualify as an incentive stock option under Section 422 of the Code, the Optionee may incur regular federal and California income tax liability upon exercise. 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. 
  

 -2- 








 (b) Disposition of Shares. If the Optionee holds the Option Shares for more
than one year, gain realized on disposition of the Shares will be treated as long-term capital gain for federal and California (and other states) income tax purposes. Long-term capital gain will be taxed for federal income tax and alternative
minimum tax purposes at a maximum rate of 20% if the Shares are held more than one year after exercise. 
  
 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 terms and conditions of the Plan and this Nonstatutory Stock Option Agreement. Optionee has reviewed the Plan and this Nonstatutory Stock Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to
executing this Nonstatutory Stock Option Agreement and fully understands all provisions of the Plan and Nonstatutory Stock 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 Nonstatutory Stock Option Agreement.
