 4 

 6. Limitations. 

(a) Each Option shall be designated in the Notice of Grant as a Nonstatutory Stock Option. 

(b) Neither the Plan nor any Option shall confer upon an Optionee any right with respect to continuing the Optionee’s
employment or consulting relationship with the Company, nor shall they interfere in any way with the Optionee’s right or the Company’s right to terminate such employment or consulting relationship at any time, with or without cause.

 (c) Any Option granted after July 19, 2002, that is subject to vesting on the basis of Continuous Status
as an Employee or Consultant shall cease to vest 90 days after the beginning of any leave(s) of absence, and shall not resume vesting until the expiration of such leave(s).

Plan. 
 8. Term of Option. The term of each Option shall be stated in the Notice of Grant. 

9. Option Exercise Price and Consideration. 

(a) Exercise Price. The per share exercise price (which in the event of a stock bonus shall be zero) 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 that 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 that 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 and, 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; 
 (v) delivery of a properly executed exercise notice together with such other
documentation as the Administrator and the broker, if applicable, shall require to effect an exercise of the Option and delivery to the Company of the sale or loan proceeds required to pay the exercise price; 

  
 5 

 (vi) any combination of the foregoing methods of payment; or 

(vii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable
Laws. 
 10. Exercise of Option. 

(a) Procedure for Exercise; Rights as a Shareholder. 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. 
 An Option may not be exercised for a fraction of a Share. 
 An
Option shall be deemed exercised when the Company receives: (i) written 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 stock certificate evidencing such Shares is 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 shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be
issued) such stock certificate 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 stock certificate is issued, except as provided in Section 12
hereof. 
 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 Continuous Status as an Employee or Consultant. In the event that an Optionee’s
Continuous Status as an Employee or Consultant terminates, the Optionee may exercise his or her Option, but only within such period of time as is determined by the Administrator, and only to the extent that the Optionee was entitled to exercise it
at the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant). If, at the date of termination, the Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable 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. 

  
 6 

 (c) Death of Optionee. Notwithstanding the provisions of
Section 10(b) above, in the event of the death of an Optionee, the entire Option may be exercised at any time within twelve (12) months following the date of death (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 acquired the right to exercise the Option by bequest or inheritance. If the Optionee’s estate or a person who acquired the right to exercise the Option by
bequest or inheritance does not exercise the Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 

11. Non-Transferability of Options. 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 not be exercised, during the lifetime of the Optionee, by any person except the Optionee, without the prior written consent of the Administrator. 

12. Adjustments Upon Changes in Capitalization, Dissolution, Merger, Asset Sale. or Change of Control.

 (a) Changes in Capitalization. Subject to any required action by the shareholders 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, to the extent that an Option has not been previously exercised, it will terminate immediately
prior to the consummation of such proposed action. The Board may, in the exercise of its sole discretion in such instances, declare that any Option shall terminate as of a date fixed by the Board and give each Optionee the right to exercise his or
her Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. 
 (c) Merger or Asset Sale. Except as otherwise specified in individual option agreements, 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 shall be substituted by the successor corporation or a Parent or 

  
 7 

 
Subsidiary of the successor corporation. In the event that the successor corporation does not agree to assume the Option or to substitute an equivalent option or right, the Option shall become
fully vested and exercisable as to all of the Optioned Stock, including Shares as to which it would not otherwise be 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 that the Option shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option will terminate upon the expiration of such period. 

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 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) Shareholder Approval. The Company shall obtain shareholder approval of any Plan amendment to the extent
necessary and desirable to comply with any applicable law, rule, or regulation, including the requirements of any exchange or quotation system on which the Common Stock is listed or quoted. Such shareholder approval, if required, shall be obtained
in such a manner and to such a degree as is required by the applicable law, rule, or regulation. 
 (c)
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. 
 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 all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended,
the Exchange Act, the rules and regulations promulgated thereunder, Applicable Laws, and the requirements of any stock exchange or quotation system upon which the Shares may then be listed or quoted, 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. 

  
 8 

 16. Liability of Company. 

(a) 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. 
 (b) Grants Exceeding Allotted Shares. If
the Optioned Stock covered by an Option exceeds, as of the date of grant, the number of Shares which may be issued under the Plan without additional shareholder approval, such Option shall be void with respect to such excess Optioned Stock, unless
shareholder approval of an amendment sufficiently increasing the number of Shares subject to the Plan is timely obtained in accordance with Section 14(b) of the Plan. 
 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.

shall be as follows:

 (D) subject to Section 10 hereof, the Options shall
become exercisable as to 100% of the Shares subject to the Option on the date of the next annual meeting of stockholders, provided that the Optionee continues to serve as a Director until such date. 

(b) Share Shortfall. In the event that any Option granted under the Plan would cause the number of Shares subject
to outstanding Options plus the number of Shares previously purchased under Options to exceed the total number of Shares reserved for issuance under the Plan, then the remaining Shares available for Option grant shall be granted under Options to the
Outside Directors on a pro rata basis. No further grants shall be made until such time, if any, as additional Shares become available for grant under the Plan through the provisions of the Plan, by action of the Board, by the stockholders approving
an increase in the number of Shares which may be issued under the Plan or through cancellation or expiration of Options previously granted hereunder. 
 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 hereof. 

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 the Director’s relationship with the Company at any time. 

6. Term of Plan. The Plan shall become effective upon the later to occur of its adoption by the Board or its approval by
the stockholders of the Company as described in Section 16 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 11 of the Plan. 

7. Form of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the
method of payment, shall consist of (i) cash, (ii) check, (iii) other Shares, which, in the case of Shares acquired from the Company, (x) have been owned by the Optionee for more than six (6) months on the date of surrender,
and (y) 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, (iv) to the extent permitted by applicable laws, including the Sarbanes-Oxley Act of
2002, consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan, or (v) any combination of the foregoing methods of payment. 

8. Exercise of Option. 
 (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable at such times as are set forth in Section 4 hereof and 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 7 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 

  
 3 

 
Shares, no right to vote or receive dividends or any other rights as a shareholder 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 shall 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 10 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 Continuous Status as a Director. Subject to Section 10 hereof, in the event an
Optionee’s status as a Director terminates (including pursuant to the Optionee’s death or disability), the Optionee may exercise his or her Option, but only within four (4) years following the date of such termination, and only to the
extent that the Optionee was entitled to exercise it on the date of such termination (but in no event later than the expiration of its ten (10) year term). To the extent that the Optionee was not vested as to his or her entire Option on the
date of such termination, 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. 
 9. Non-Transferability of Options. Except as determined
otherwise by the Board, Options 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. 
 10. Adjustments, Dissolution, Merger or Asset Sale. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock,
other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other
change in the corporate structure of the Company affecting the Common Stock such that an adjustment is determined by the Board (in its sole discretion) to be appropriate in order to prevent dilution or enlargement of the benefits or potential
benefits intended to be made available under the Plan, then the Board shall, in such manner as it may deem equitable, adjust the number and class of Common Stock which may be delivered under the Plan, the purchase price per Share and the number of
Shares covered by each Option which has not yet been exercised, and the number of Shares subject to Options granted pursuant to Section 4. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, to the extent that an Option has not been previously exercised, it shall 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, outstanding Options may be assumed or equivalent options may be substituted by the successor corporation or a Parent or
Subsidiary thereof (the “Successor Corporation”). If an Option is assumed or substituted for, the Option or equivalent option shall continue to be exercisable as provided in Section 4 hereof for so long as the Optionee serves as a
Director or a director of the Successor Corporation. Following such assumption or substitution, if the Optionee’s status as a Director or director of the Successor Corporation, as applicable, is terminated (other than upon a voluntary
resignation by the Optionee that is not requested by the Successor Corporation or a cessation of Board service due to the Optionee’s death or permanent and total disability), the Option or option shall become fully exercisable, including as to
Shares for which it would not otherwise be exercisable. Thereafter, the Option or option shall remain exercisable in accordance with Section 8(b) above. 

  
 4 

 If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and exercisable, including as to Shares for which it would not otherwise be exercisable. In such event the Board shall notify the Optionee that the Option shall be fully
exercisable for a period of thirty (30) days from the date of such notice, and upon the expiration of such period the Option shall terminate. 
 For the purposes of this Section 10(c), an Option shall be considered assumed if, following the merger or sale of assets, the Option confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Option 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). 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 subject to the Option, 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. 

11. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Board may at any time amend, alter, suspend, or discontinue the Plan, but no
amendment, alteration, suspension, or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with any
applicable law, regulation or stock exchange rule, the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required. 

(b) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not
adversely affect Options already granted unless the Optionee’s consent is obtained. 
 (c) No Repricing
Without Shareholder Approval. Options granted hereunder shall not be repriced, including by means of an option exchange, unless such repricing is approved in advance by the Company’s stockholders. 

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 hereof. 
 13. Conditions Upon Issuance of Shares. 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 pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, state securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel
for the Company with respect to such compliance. 
 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 any of the aforementioned relevant provisions of law. 

  
 5 

 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. 
 14. 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. 
 15. Option Agreement. Options shall be evidenced by written option agreements in such form as the Board shall approve.
