are hereafter increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of a recapitalization, stock split, reverse stock split, combination of shares, reclassification,

subject to outstanding Option Agreements and Stock Purchase Agreements and the limit on the number of shares under Section 3.3, all in order to preserve, as nearly as practical, but not to increase, the benefits to Participants. 
 ARTICLE 5. 
 OPTIONS 

5.1 Option Agreement. Each Option granted pursuant to this Plan shall be evidenced by an Option Agreement that shall specify the number
of shares subject thereto, the Exercise Price per share, and whether the Option is an Incentive Option or Nonqualified Option. As soon as is practical following the grant of an Option, an Option Agreement shall be duly executed and delivered by or
on behalf of the Company to the Optionee to whom such Option was granted. Each Option Agreement shall be in such form and contain such additional terms and conditions, not inconsistent with the provisions of this Plan, as the Administrator shall,
from time to time, deem desirable, including, without limitation, the imposition of any rights of first refusal and resale obligations upon any shares of Common Stock acquired pursuant to an Option Agreement. Each Option Agreement may be different
from each other Option Agreement. 
 5.2 Exercise Price. The Exercise Price per share of Common Stock covered by each Option
shall be determined by the Administrator, subject to the following: (a) the Exercise Price of an Incentive Option shall not be less than 100% of Fair Market Value on the date the Incentive Option is granted, (b) the Exercise Price of a
Nonqualified Option shall not be less than 85% of Fair Market Value on the date the Nonqualified Option is granted, and (c) if the person to whom an Option is granted is a 10% Shareholder on the date of grant, the Exercise Price shall not be
less than 110% of Fair Market Value on the date the Option is granted. However, an Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution
for another option in a manner satisfying the provisions of Section 424 of the Code. 
 5.3 Payment of Exercise Price.
Payment of the Exercise Price shall be made upon exercise of an Option and may be made, in the discretion of the Administrator, subject to any legal restrictions, by: (a) cash; (b) check; (c) the surrender of shares of Common Stock
acquired pursuant to the exercise of an Option (provided that shares acquired pursuant to the exercise of options granted by the Company must have been held by the Optionee for the requisite period necessary to avoid a charge to the Company’s
earnings for financial reporting purposes), which surrendered shares shall be valued at Fair Market Value as of the date of such exercise; (d) the Optionee’s promissory note in a form and on terms acceptable to the Administrator, provided
that an amount equal to at least the aggregate par value of the shares purchased upon exercise of an Option shall be paid in such other form of consideration permitted under the Delaware General Corporation Law; (e) the cancellation of
indebtedness of the Company to the Optionee; (f) the waiver of compensation due or accrued to the Optionee for services rendered; (g) provided that a public market for the Common Stock exists, a “same day sale” commitment from
the Optionee and an NASD Dealer whereby the Optionee 

  

 5 

 
irrevocably elects to exercise the Option and to sell a portion of the shares so purchased to pay for the Exercise Price and whereby the NASD Dealer
irrevocably commits upon receipt of such shares to forward the Exercise Price directly to the Company; (h) provided that a public market for the Common Stock exists, a “margin” commitment from the Optionee and an NASD Dealer whereby
the Optionee irrevocably elects to exercise the Option and to pledge the shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the Exercise Price, and whereby the NASD Dealer
irrevocably commits upon receipt of such shares to forward the Exercise Price directly to the Company; or (i) any combination of the foregoing methods of payment or any other consideration or method of payment as shall be permitted by
applicable corporate law. 
 5.4 Term and Termination of Options. The term and provisions for termination of each Option shall
be as fixed by the Administrator, but no Option may be exercisable more than ten (10) years after the date it is granted. An Incentive Option granted to a person who is a 10% Shareholder on the date of grant shall not be exercisable more than
five (5) years after the date it is granted. 
 5.5 Vesting and Exercise of Options. Each Option shall vest and become
exercisable in one or more installments at such time or times and subject to such conditions, including without limitation the achievement of specified performance goals or objectives, as shall be determined by the Administrator. An Option granted
to an employee who is not an officer, a director or Consultant of the Company must vest at a rate of at least 20% per year over a period of five years from the date of grant, subject to reasonable conditions such as continued employment.
Notwithstanding the foregoing, to the extent required by applicable law, each Option shall provide that the Optionee shall have the right to exercise the vested portion of any Option held at termination for at least 30 days following termination for
any reason, and that the Optionee shall have the right to exercise the Option for at least six months if such termination was due to the death or Disability of the Optionee. 
 5.6 Annual Limit on Incentive Options. To the extent required for “incentive stock option” treatment under Section 422 of
the Code, the aggregate Fair Market Value (determined as of the time of grant) of the Common Stock shall not, with respect to which Incentive Options granted under this Plan and any other plan of the Company or any Affiliated Company become
exercisable for the first time by an Optionee during any calendar year, exceed $100,000. 
 5.7 Nontransferability of Options.
No Option shall be assignable or transferable except by will or the laws of descent and distribution, and during the life of the Optionee shall be exercisable only by such Optionee. 
 5.8 Rights as Stockholder. An Optionee or permitted transferee of an Option shall have no rights or privileges as a stockholder with
respect to any shares covered by an Option until such Option has been duly exercised and certificates representing shares purchased upon such exercise have been issued to such person. 
 5.9 Unvested Shares. The Administrator shall have the discretion to grant Options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease being an employee, a Service Provider, an officer, director or Consultant of the Company while owning such unvested shares, the Company shall have the right to repurchase, at the exercise price paid per share, any or
all of those unvested shares. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the 

  

 6 

 
purchased shares) shall be established by the Administrator and set forth in the document evidencing such repurchase right. The Administrator may not impose
a vesting schedule upon any Option grant or the shares of Common Stock subject to that Option which is more restrictive than twenty percent (20%) per year vesting, with the initial vesting to occur not later than one (1) year after the
Option grant date. However, such limitation shall not be applicable to any Option grants made to individuals who are officers, directors or Consultants of the Company. 
 ARTICLE 6. 
 RESTRICTED STOCK 
 6.1 Issuance and Sale of Restricted Stock. The Administrator shall have the right to issue shares of Common Stock subject to such terms,
restrictions and conditions as the Administrator may determine at the time of grant (“Restricted Stock”). Such conditions may include, but are not limited to, continued employment or the achievement of specified performance goals or
objectives. The Purchase Price of Restricted Stock shall be determined by the Administrator, provided that (a) the Purchase Price shall not be less than 85% of Fair Market Value of the stock on the date the Restricted Stock is granted or at the
time the purchase is consummated, or (b) if the person to whom a right to purchase Restricted Stock is granted is a 10% Shareholder on the date of grant, the Purchase Price shall not be less than 100% of Fair Market Value of the stock on the
date the Restricted Stock is granted or at the time the purchase is consummated. 
 6.2 Restricted Stock Purchase Agreements. A
Participant shall have no rights with respect to the shares of Restricted Stock covered by a Stock Purchase Agreement until the Participant has paid the full Purchase Price to the Company in the manner set forth in Section 6.3 hereof and has
executed and delivered to the Company the Stock Purchase Agreement. Each Stock Purchase Agreement shall be in such form, and shall set forth the Purchase Price and such other terms, conditions and restrictions of the Restricted Stock, not
inconsistent with the provisions of this Plan, as the Administrator shall, from time to time, deem desirable. Each Stock Purchase Agreement may be different from each other Stock Purchase Agreement. 
 6.3 Payment of Purchase Price. Subject to any legal restrictions, payment of the Purchase Price may be made, in the discretion of the
Administrator, by: (a) cash; (b) check; (c) the surrender of shares of Common Stock owned by the Participant that have been held by the Participant for the requisite period necessary to avoid a charge to the Company’s earnings
for financial reporting purposes, which surrendered shares shall be valued at Fair Market Value as of the date of such acceptance; (d) the Participant’s promissory note in a form and on terms acceptable to the Administrator, provided that
an amount equal to at least the aggregate par value of the shares purchased pursuant to a Stock Purchase Agreement shall be paid in such other form of consideration permitted under the Delaware General Corporation Law; (e) the cancellation of
indebtedness of the Company to the Participant; (f) the waiver of compensation due or accrued to the Participant for services rendered; or (g) any combination of the foregoing methods of payment or any other consideration or method of
payment as shall be permitted by applicable corporate law. 
 6.4 Rights as a Stockholder. Upon complying with the provisions
of Section 6.2 hereof, a Participant shall have the rights of a stockholder with respect to the Restricted Stock purchased pursuant to a Stock Purchase Agreement, including voting and dividend rights, subject to the terms, restrictions and
conditions as are set forth in such Stock Purchase Agreement. Unless the Administrator shall determine otherwise, certificates evidencing shares of Restricted Stock shall remain in the possession of the Company until such shares have vested in
accordance with the terms of the Stock Purchase Agreement. 
  

 7 

 6.5 Restrictions. Shares of Restricted Stock may not be sold, assigned, transferred,
pledged or otherwise encumbered or disposed of except as specifically provided in the Stock Purchase Agreement. In the event of termination of a Participant’s employment, service as a director of the Company or Service Provider status for any
reason whatsoever (including death or disability), the Stock Purchase Agreement may provide, in the discretion of the Administrator, that the Company shall have the right, exercisable at the discretion of the Administrator, to repurchase (i) at
the original Purchase Price, any shares of Restricted Stock which have not vested as of the date of termination (provided that the right to repurchase at the original Purchase Price shall lapse at the rate of at least 20% per year over five
(5) years from the date of the Stock Purchase Agreement for Participants other than directors, officers and consultants of the Company), and (ii) at Fair Market Value, any shares of Restricted Stock which have vested as of such date, on
such terms as may be provided in the Stock Purchase Agreement. 
 In any event, the right to repurchase must be exercised within sixty
(60) days of the termination of Participant’s Continuous Service and may be paid by the Company or its assignee, by cash, check, or cancellation of indebtedness within thirty (30) days of the expiration of the right to exercise.

 6.6 Vesting of Restricted Stock. The Stock Purchase Agreement shall specify the date or dates, the performance goals or
objectives which must be achieved, and any other conditions on which the Restricted Stock may vest. A Stock Purchase Agreement awarded to an employee who is not an officer, director, or Consultant of the Company must vest at a rate of at least
20% per year over a period of five years from the date of grant, subject to reasonable conditions such as continued employment. 
 6.7 Dividends. If payment for shares of Restricted Stock is made by promissory note, any cash dividends paid with respect to the Restricted Stock may be applied, in the discretion of the Administrator, to repayment of such
note. 
 ARTICLE 7. 
 ADMINISTRATION OF THE PLAN 
 7.1 Administrator. Authority to control and manage the operation and
administration of the Plan shall be vested in the Board, which may delegate such responsibilities in whole or in part to a committee consisting of two (2) or more members of the Board (the “Committee”). Members of the Committee may be
appointed from time to time by, and shall serve at the pleasure of, the Board. The Board may limit the composition of the Committee to those persons necessary to comply with the requirements of Section 162(m) of the Code and Section 16 of
the Exchange Act. As used herein, the term “Administrator” means the Board or, with respect to any matter as to which responsibility has been delegated to the Committee, the term Administrator shall mean the Committee. 
 7.2 Powers of the Administrator. In addition to any other powers or authority conferred upon the Administrator elsewhere in the Plan or by
law, the Administrator shall have full power and authority: (a) to determine the persons to whom, and the time or times at which, Incentive 

  

 8 

 
Options or Nonqualified Options or rights to purchase Restricted Stock shall be granted, the number of shares to be represented by each Option and the number
of shares of Restricted Stock to be offered, and the consideration to be received by the Company upon the exercise of such Options or sale of such Restricted Stock; (b) to interpret the Plan; (c) to create, amend or rescind rules and
regulations relating to the Plan; (d) to determine the terms, conditions and restrictions contained in, and the form of, Option Agreements and Stock Purchase Agreements; (e) to determine the identity or capacity of any persons who may be
entitled to exercise a Participant’s rights under any Option or Stock Purchase Agreement under the Plan; (f) to correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any Option Agreement or Stock

Stock; (i) to provide for rights of first refusal and/or repurchase rights; (j) to amend outstanding Option Agreements and Stock Purchase Agreements to provide for, among other things, any change or modification which the Administrator
could have included in the original Agreement or in furtherance of the powers provided for herein; and (k) to make all other determinations necessary or advisable for the administration of the Plan, but only to the extent not contrary to the
express provisions of the Plan. Any action, decision, interpretation or determination made in good faith by the Administrator in the exercise of its authority conferred upon it under the Plan shall be final and binding on the Company and all
Participants. 
 7.3 Limitation on Liability. No employee of the Company or member of the Board or Committee shall be subject
to any liability with respect to duties under the Plan unless the person acts fraudulently or in bad faith. To the extent permitted by law, the Company shall indemnify each member of the Board or Committee, and any employee of the Company with
duties under the Plan, who was or is a party, or is threatened to be made a party, to any threatened, pending or completed proceeding, whether civil, criminal, administrative or investigative, by reason of such person’s conduct in the
performance of duties under the Plan. 
 ARTICLE 8. 
 CHANGE IN CONTROL 
 8.1 Change in Control. In order to preserve a Participant’s
rights in the event of a Change in Control of the Company: 
 (a) The Administrator shall have the discretion to
provide the extent (if any) to which vesting of an Option shall occur upon the consummation of a Change in Control, as well as the discretion to determine the terms and conditions by which each such Option shall so vest. Such discretion shall be
with respect to each Option, and may be different than other Options currently issued or that may be issued. 
 (b) The
Administrator can determine, in each Option Agreement, the extent to which: (i) the Options (including the unvested portion thereof) are to be assumed by the acquiring or successor entity (or parent thereof) or new options of comparable value
are to be issued in exchange therefor pursuant to the terms of the Change in Control transaction, or (ii) the Options (including the unvested portion thereof) are to be replaced by the acquiring or successor entity (or parent thereof) with
other incentives of comparable value under a new incentive program (“New Incentives”) containing such terms and provisions as the Administrator in its discretion may consider equitable. If outstanding Options are assumed, or if new options
of comparable value are issued in exchange 

  

 9 

 
therefor, then each such Option or new option shall be appropriately adjusted, concurrently with the Change in Control, to apply to the number and class of
securities or other property that the Participant would have received pursuant to the Change in Control transaction in exchange for the shares issuable upon exercise of the Option had the Option been exercised immediately prior to the Change in
Control, and appropriate adjustment also shall be made to the Exercise Price such that the aggregate Exercise Price of each such Option or new option shall remain the same as nearly as practicable. 
 (c) To the extent that Options will accelerate pursuant to a Change in Control, the Administrator in its discretion may provide, in
connection with such Change in Control transaction, for the purchase or exchange of each Option for an amount of cash or other property having a value equal to the difference (or “spread”) between: (x) the value of the cash or other
property that the Participant would have received pursuant to the Change in Control transaction in exchange for the shares issuable upon exercise of the Option had the Option been exercised immediately prior to the Change in Control, and
(y) the Exercise Price of the Option. 
 (d) The Administrator in its discretion may provide in each Stock
Purchase Agreement the extent (if any) to which Repurchase Rights shall terminate, and thus the extent (if any) to which shares of Common Stock subject to such terminated Repurchase Rights vest, immediately prior to the consummation of a Change in
Control of the Company. In addition, the Administrator may provide that in connection with such Change in Control, the acquiring or successor entity (or parent thereof) may provide for the continuance or assumption of Stock Purchase Agreements or
the substitution of new agreements of comparable value covering shares of a successor corporation, with appropriate adjustments as to the number and kind of shares and purchase price. 
 (e) Outstanding Options shall terminate and cease to be exercisable upon consummation of a Change in Control except to the extent
that the Options are assumed by the successor entity (or parent thereof) or new options of comparable value or New Incentives are issued in exchange therefor pursuant to the terms of the Change in Control transaction. 
 (f) The Administrator shall cause written notice of the proposed Change in Control transaction to be given to Participants not less
than fifteen (15) days prior to the anticipated effective date of the proposed transaction. 
 ARTICLE 9. 
 AMENDMENT AND TERMINATION OF THE PLAN 
 9.1 Amendments. The Board may from time to time alter, amend, suspend or terminate the Plan in such respects as the Board may deem advisable. No such alteration, amendment, suspension or termination shall be made which shall
substantially affect or impair the rights of any Participant under an outstanding Option Agreement or Stock Purchase Agreement without such Participant’s consent. The Board may alter or amend the Plan to comply with requirements under the Code
relating to Incentive Options or other types of options which give Optionees more favorable tax treatment than that applicable to Options granted under this Plan as of the date of its adoption. Upon any such alteration or amendment, any outstanding
Option granted hereunder may, if the Administrator so determines and if permitted by applicable law, be subject to the more favorable tax treatment afforded to an Optionee pursuant to such terms and conditions. 
  

 10 

 9.2 Plan Termination. Unless the Plan shall theretofore have been terminated, the Plan
shall terminate on the tenth (10th) anniversary of the Effective Date or the tenth (10th) anniversary of the date the Plan is approved by the stockholders of the Company, whichever is earlier, and no Options or Rights to Purchase may be
granted under the Plan thereafter, but Option Agreements, Stock Purchase Agreements and Rights to Purchase then outstanding shall continue in effect in accordance with their respective terms. 
 ARTICLE 10. 
 TAX WITHHOLDING 
 10.1 Withholding. The Company shall have the power to withhold, or require a Participant to remit to the Company, an amount sufficient to
satisfy any applicable Federal, state, and local tax withholding requirements with respect to any Options exercised or Restricted Stock issued under the Plan. To the extent permissible under applicable tax, securities and other laws, the
Administrator may, in its sole discretion and upon such terms and conditions as it may deem appropriate, permit a Participant to satisfy his or her obligation to pay any such tax, in whole or in part, up to an amount determined on the basis of the
highest marginal tax rate applicable to such Participant, by (a) directing the Company to apply shares of Common Stock to which the Participant is entitled as a result of the exercise of an Option or as a result of the purchase of or lapse of
restrictions on Restricted Stock or (b) delivering to the Company shares of Common Stock owned by the Participant. The shares of Common Stock so applied or delivered in satisfaction of the Participant’s tax withholding obligation shall be
valued at their Fair Market Value as of the date of measurement of the amount of income subject to withholding. 
 ARTICLE 11.

 MISCELLANEOUS 
 11.1 Benefits Not Alienable. Other than as provided above, benefits under the Plan may not be assigned or alienated, whether voluntarily or involuntarily. Any unauthorized attempt at assignment, transfer, pledge or other
disposition shall be without effect. 
 11.2 No Enlargement of Employee Rights. This Plan is strictly a voluntary undertaking
on the part of the Company and shall not be deemed to constitute a contract between the Company and any Participant to be consideration for, or an inducement to, or a condition of, the employment of any Participant. Nothing contained in the Plan
shall be deemed to give the right to any Participant to be retained as an employee of the Company or any Affiliated Company or to limit the right of the Company or any Affiliated Company to discharge any Participant at any time. 
 11.3 Application of Funds. The proceeds received by the Company from the sale of Common Stock pursuant to Option Agreements and Stock
Purchase Agreements, except as otherwise provided herein, will be used for general corporate purposes.

 12Form of Stock Option Agreement under 2002 Stock Incentive Plan

 Exhibit 10.6 
 Option No.             
 THEROX, INC. 

STOCK OPTION AGREEMENT 
 Type of Option (check one):     ̈  Incentive         ̈  Nonqualified 

 This Stock Option Agreement (the “Agreement”) is entered into as of ________, 200__, by and between THEROX, INC., a
Delaware corporation (the “Company”), and
                                         
    (the “Optionee”) pursuant to the Company’s 2002 Stock Incentive Plan, as amended (the “Plan”). Any capitalized term not defined herein shall have the same meaning ascribed to it in the Plan. 

1. Grant of Option. The Company hereby grants to Optionee an option (the “Option”) to purchase all or any portion of a total
of
                                         
                               
(            ) shares (the “Shares”) of the Common Stock of the Company at a purchase price of
                            
($             ) per share (the “Exercise Price”), subject to the terms and conditions set forth herein and the provisions of the Plan. If the box marked
“Incentive” above is checked, then this Option is intended to qualify as an “incentive stock option” as defined in Section 422 of the Internal Revenue Code of l986, as amended (the “Code”). If this Option fails in
whole or in part to qualify as an incentive stock option, or if the box marked “Nonqualified” is checked, then this Option shall to that extent constitute a nonqualified stock option. 
 2. Vesting of Option. The right to exercise this Option shall vest in installments, and this Option shall be exercisable from time to time
in whole or in part as to any vested installment (“Vested Shares”).                      of the Shares shall become Vested Shares on
the              month anniversary of the “Vesting Commencement Date,” and thereafter, the balance of the Shares shall become Vested Shares in a series of
                     successive equal monthly installments for each full month of Continuous Service provided by the Optionee, such that 100%
of the Shares shall become Vested Shares on the fourth anniversary of the “Vesting Commencement Date.” For these purposes, the Vesting Commencement Date shall be
                    . 
 No
additional Shares shall vest after the date of termination of Optionee’s “Continuous Service” (as defined below), but this Option shall continue to be exercisable in accordance with Section 3 hereof with respect to that number of
shares that have vested as of the date of termination of Optionee’s Continuous Service. 
 For purposes of this Agreement, the term
“Continuous Service” means (i) employment by either the Company or any parent or subsidiary corporation of the Company, or by a corporation or a parent or subsidiary of a corporation issuing or assuming a stock option in a transaction
to which Section 424(a) of the Code applies, which is uninterrupted except for vacations, illness (except for permanent disability, as defined in Section 22(e)(3) of the Code), or leaves of absence which are approved in writing by the
Company or any of such other employer corporations, if applicable, (ii) service as a member of the Board of Directors of the Company until Optionee resigns, is removed from office, or Optionee’s term of office expires and he or she is not
reelected, or (iii) so long as Optionee is engaged as a Consultant or Service Provider. 

 3. Term of Option. The right of the Optionee to exercise this Option shall terminate upon
the first to occur of the following: 
 (a) the expiration of ten (10) years from the date of this Agreement; 

(b) the expiration of one (1) year from the date of termination of Optionee’s Continuous Service if such termination is due
to permanent disability of the Optionee (as defined in Section 22(e)(3) of the Code); 
 (c) the expiration of one
(1) year from the date of termination of Optionee’s Continuous Service if such termination is due to Optionee’s death or if death occurs during either the three-month or one-month period following termination of Optionee’s
Continuous Service pursuant to Section 3(d) or 3(e) below, as the case may be; 
 (d) the expiration of three
(3) months from the date of termination of Optionee’s Continuous Service if such termination occurs for any reason other than permanent disability, death, voluntary resignation or cause; provided, however, that if Optionee dies during such
three-month period the provisions of Section 3(c) above shall apply; 
 (e) the expiration of one (1) month from the
date of termination of Optionee’s Continuous Service if such termination occurs due to voluntary resignation; provided, however, that if Optionee dies during such one-month period the provisions of Section 3(c) above shall apply;

 (f) the termination of Optionee’s Continuous Service, if such termination is for cause; or 
 (g) upon the consummation of a “Change in Control” (as defined in Section 2.4 of the Plan), unless otherwise provided
pursuant to Section 11 below. 
 4. Exercise of Option. On or after the vesting of any portion of this Option in
accordance with Sections 2 or 11 hereof, and until termination of the right to exercise this Option in accordance with Section 3 above, the portion of this Option that has vested may be exercised in whole or in part by the Optionee (or, after
his or her death, by the person designated in Section 5 below) upon delivery of the following to the Company at its principal executive offices: 
 (a) a written notice of exercise which identifies this Agreement and states the number of Shares then being purchased (but no fractional Shares may be purchased), with any partial exercise being deemed to cover first
vested Shares and then the earliest vesting installments of unvested Shares; 
 (b) a check or cash in the amount of the
Exercise Price (or payment of the Exercise Price in such other form of lawful consideration as the Administrator may approve from time to time under the provisions of Section 5.3 of the Plan); 
 (c) a check or cash in the amount reasonably requested by the Company to satisfy the Company’s withholding obligations under federal,
state or other applicable tax laws with respect to the taxable income, if any, recognized by the Optionee in connection with the exercise of this Option (unless the Company and Optionee shall have made other arrangements for deductions or
withholding from Optionee’s wages, bonus or other compensation payable to Optionee, or by the withholding of Shares issuable upon exercise of this Option or the delivery of Shares owned by the Optionee in accordance with Section 10.1 of
the Plan, provided such arrangements satisfy the requirements of applicable tax laws); and 
  

 2 

 (d) a letter, if requested by the Company, in such form and substance as the Company may
require, setting forth the investment intent of the Optionee, or person designated in Section 5 below, as the case may be. 
 5.
Death of Optionee; No Assignment. The rights of the Optionee under this Agreement may not be assigned or transferred except by will or by the laws of descent and distribution, and may be exercised during the lifetime of the Optionee only
by such Optionee. Any attempt to sell, pledge, assign, hypothecate, transfer or dispose of this Option in contravention of this Agreement or the Plan shall be void and shall have no effect. If the Optionee’s Continuous Service terminates as a
result of his or her death, and provided Optionee’s rights hereunder shall have vested pursuant to Section 2 hereof, Optionee’s legal representative, his or her legatee, or the person who acquired the right to exercise this Option by
reason of the death of the Optionee (individually, a “Successor”) shall succeed to the Optionee’s rights and obligations under this Agreement. After the death of the Optionee, only a Successor may exercise this Option. 
 6. Representations and Warranties of Optionee. 
 (a) Optionee represents and warrants that this Option is being acquired by Optionee for Optionee’s personal account, for investment
purposes only, and not with a view to the distribution, resale or other disposition thereof. 
 (b) Optionee acknowledges that
the Company may issue Shares upon the exercise of the Option without registering such Shares under the Securities Act of l933, as amended (the “Securities Act”), on the basis of certain exemptions from such registration requirement.
Accordingly, Optionee agrees that his or her exercise of the Option may be expressly conditioned upon his or her delivery to the Company of an investment certificate including such representations and undertakings as the Company may reasonably
require in order to assure the availability of such exemptions, including a representation that Optionee is acquiring the Shares for investment and not with a present intention of selling or otherwise disposing thereof and an agreement by Optionee
that the certificates evidencing the Shares may bear a legend indicating such non-registration under the Securities Act and the resulting restrictions on transfer. Optionee acknowledges that, because Shares received upon exercise of an Option may be
unregistered, Optionee may be required to hold the Shares indefinitely unless they are subsequently registered for resale under the Securities Act or an exemption from such registration is available. 
 (c) Optionee acknowledges receipt of a copy of the Plan and understands that all rights and obligations connected with this Option are set
forth in this Agreement and in the Plan. 
 7. Right of First Refusal. 
 (a) The Shares acquired pursuant to the exercise of this Option may be sold by the Optionee only in compliance with the provisions of this
Section 7, and subject in all cases to compliance with the provisions of Section 6(b) hereof. Prior to any intended sale, Optionee shall first give written notice (the “Offer Notice”) to the Company specifying (i) his or her
bona fide intention to sell or otherwise transfer such Shares, (ii) the name and address of the proposed 

  

 3 

 
purchaser(s), (iii) the number of Shares the Optionee proposes to sell (the “Offered Shares”), (iv) the price for which he or she
proposes to sell the Offered Shares, and (v) all other material terms and conditions of the proposed sale. 
 (b) Within
30 days after receipt of the Offer Notice, the Company or its nominee(s) may elect to purchase all or any portion of the Offered Shares at the price and on the terms and conditions set forth in the Offer Notice by delivery of written notice (the
“Acceptance Notice”) to the Optionee specifying the number of Offered Shares that the Company or its nominees elect to purchase. Within 15 days after delivery of the Acceptance Notice to the Optionee, the Company and/or its nominee(s)
shall deliver to the Optionee payment of the amount of the purchase price of the Offered Shares to be purchased pursuant to this Section 7, against delivery by the Optionee of a certificate or certificates representing the Offered Shares to be
purchased, duly endorsed for transfer to the Company or such nominee(s), as the case may be. Payment shall be made on the same terms as set forth in the Offer Notice or, at the election of the Company or its nominees(s), by check or wire transfer of
funds. If the Company and/or its nominee(s) do not elect to purchase all of the Offered Shares, the Optionee shall be entitled to sell the balance of the Offered Shares to the purchaser(s) named in the Offer Notice at the price specified in the
Offer Notice or at a higher price and on the terms and conditions set forth in the Offer Notice; provided, however, that such sale or other transfer must be consummated within 60 days from the date of the Offer Notice and any proposed sale after
such 60-day period may be made only by again complying with the procedures set forth in this Section 7. 
 (c) The
Optionee may transfer all or any portion of the Shares to a trust established for the sole benefit of the Optionee and/or his or her spouse or children without such transfer being subject to the right of first refusal set forth in this
Section 7, provided that the Shares so transferred shall remain subject to the terms and conditions of this Agreement and no further transfer of such Shares may be made without complying with the provisions of this Section 7. 

(d) Any Successor of Optionee pursuant to Section 5 hereof, and any transferee of the Shares pursuant to this Section 7,
shall hold the Shares subject to the terms and conditions of this Agreement and no further transfer of the Shares may be made without complying with the provisions of this Section 7. 
 (e) The rights provided the Company and its nominee(s) under this Section 7 shall terminate upon the closing of the initial public
offering of shares of the Company’s Common Stock pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act. 
 8. Company’s Repurchase Right. 
 (a) The Company shall have the right (but not the obligation) to repurchase (the “Repurchase Right”) any or all of the Shares acquired pursuant to the exercise of this Option in the event that the
Optionee’s Continuous Service should terminate for any reason whatsoever, including without limitation Optionee’s death, disability, voluntary resignation or termination by the Company with or without cause. Upon exercise of the Repurchase
Right, the Optionee shall be obligated to sell his or her Shares to the Company, as provided in this Section 8. The Repurchase Right may be exercised by the Company at any time during the period commencing on the date of termination of
Optionee’s Continuous Service and ending sixty (60) days after the last to occur of the following: 
 (i) the
termination of Optionee’s Continuous Service; 
  

 4 

 (ii) the expiration of Optionee’s right to exercise this Option pursuant to
Section 3 hereof; or 
 (iii) in the event of Optionee’s death, receipt by the Company of notice of the identity and
address of Optionee’s Successor (as defined in Section 5 hereof). 
 (b) The purchase price for Shares repurchased
hereunder (the “Repurchase Price”) shall be the Fair Market Value per share of Common Stock (determined in accordance with Section 2.14 of the Plan) as of the date of termination of Optionee’s Continuous Service. 
 (c) Written notice of exercise of the Repurchase Right, stating the number of Shares to be repurchased and the Repurchase Price per Share,
shall be given by the Company to the Optionee or his or her Successor, as the case may be, during the period specified in Section 8(a) above. 
 (d) The Repurchase Price shall be payable, at the option of the Company, by check or by cancellation of all or a portion of any outstanding indebtedness of Optionee to the Company, or by any combination thereof. The
Repurchase Price shall be paid without interest within thirty (30) days after delivery of the notice of exercise of the Repurchase Right, against delivery by the Optionee or his or her Successor of a certificate or certificates representing the
Shares to be repurchased, duly endorsed for transfer to the Company. 
 (e) The rights provided the Company under this
Section 8 shall terminate upon the closing of the initial public offering of shares of the Company’s Common Stock pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the
Securities Act. 
 9. Restrictive Legends. 
 (a) Optionee hereby acknowledges that federal securities laws and the securities laws of the state in which he or she resides may require
the placement of certain restrictive legends upon the Shares issued upon exercise of this Option, and Optionee hereby consents to the placing of any such legends upon certificates evidencing the Shares as the Company, or its counsel, may deem
necessary or advisable. 
 (b) In addition, all stock certificates evidencing the Shares shall be imprinted with a legend
substantially as follows: 
 “THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A
RIGHT OF FIRST REFUSAL IN FAVOR OF THE COMPANY AND/OR ITS NOMINEE(S), AS SET FORTH IN A STOCK OPTION AGREEMENT DATED                 
        , 200_. TRANSFER OF THESE SHARES MAY BE MADE ONLY IN COMPLIANCE WITH THE PROVISIONS OF SAID AGREEMENT, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF SAID CORPORATION. SUCH TRANSFER
RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.” 
  

 5 

 10. Adjustments Upon Changes in Capital Structure. In the event that the outstanding shares
of Common Stock of the Company are hereafter increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of a recapitalization, stock split, combination of shares,
reclassification, stock dividend or other change in the capital structure of the Company, then appropriate adjustment shall be made by the Administrator to the number of Shares subject to the unexercised portion of this Option and to the Exercise
Price per share, in order to preserve, as nearly as practical, but not to increase, the benefits of the Optionee under this Option, in accordance with the provisions of Section 4.3 of the Plan. 
 11. Change in Control. In the event of a Change in Control (as defined in Section 2.4 of the Plan): 
 (a) The right to exercise this Option shall accelerate automatically and vest in full (notwithstanding the provisions of Section 2
above) effective as of immediately prior to the consummation of the Change in Control unless this Option is to be assumed by the acquiring or successor entity (or parent thereof) or a new option or New Incentives are to be issued in exchange
therefor, as provided in subsection (b) below. If vesting of this Option will accelerate pursuant to the preceding sentence, the Administrator in its discretion may provide, in connection with the Change in Control transaction, for the purchase
or exchange of this Option for an amount of cash or other property having a value equal to the difference (or “spread”) between: (x) the value of the cash or other property that the Optionee would have received pursuant to the Change
in Control transaction in exchange for the Shares issuable upon exercise of this Option had this Option been exercised immediately prior to the Change in Control, and (y) the aggregate Exercise Price for such Shares. If the vesting of this
Option will accelerate pursuant to this subsection (a), then the Administrator shall cause written notice of the Change in Control transaction to be given to the Optionee not less than fifteen (15) days prior to the anticipated effective date
of the proposed transaction. 
 (b) The vesting of this Option shall not accelerate if and to the extent that: (i) this
Option (including the unvested portion thereof) is to be assumed by the acquiring or successor entity (or parent thereof) or a new option of comparable value is to be issued in exchange therefor pursuant to the terms of the Change in Control
transaction, or (ii) this Option (including the unvested portion thereof) is to be replaced by the acquiring or successor entity (or parent thereof) with other incentives of comparable value under a new incentive program (“New
Incentives”) containing such terms and provisions as the Administrator in its discretion may consider equitable. If this Option is assumed, or if a new option of comparable value is issued in exchange therefor, then this Option or the new
option shall be appropriately adjusted, concurrently with the Change in Control, to apply to the number and class of securities or other property that the Optionee would have received pursuant to the Change in Control transaction in exchange for the
Shares issuable upon exercise of this Option had this Option been exercised immediately prior to the Change in Control, and appropriate adjustment also shall be made to the Exercise Price such that the aggregate Exercise Price of this Option or the
new option shall remain the same as nearly as practicable. 
  

 6 

 12. Limitation of Company’s Liability for Nonissuance. The Company agrees to use its
reasonable best efforts to obtain from any applicable regulatory agency such authority or approval as may be required in order to issue and sell the Shares to the Optionee pursuant to this Option. Inability of the Company to obtain, from any such
regulatory agency, authority or approval deemed by the Company’s counsel to be necessary for the lawful issuance and sale of the Shares hereunder and under the Plan shall relieve the Company of any liability in respect of the nonissuance or
sale of such shares as to which such requisite authority or approval shall not have been obtained. 
 13. No Employment Contract
Created. Neither the granting of this Option nor the exercise hereof shall be construed as granting to the Optionee any right with respect to continuance of employment by the Company or any of its subsidiaries. The right of the Company or
any of its subsidiaries to terminate at will the Optionee’s employment at any time (whether by dismissal, discharge or otherwise), with or without cause, is specifically reserved. 
 14. Rights as Shareholder. The Optionee (or transferee of this option by will or by the laws of descent and distribution) shall have no
rights as a shareholder with respect to any Shares covered by this Option until such person has duly exercised this Option, paid the Exercise Price and become a holder of record of the Shares purchased. 
 15. “Market Stand-Off” Agreement. Optionee agrees that, if requested by the Company or the managing underwriter of any proposed
public offering of the Company’s securities, Optionee will not sell or otherwise transfer or dispose of any Shares held by Optionee without the prior written consent of the Company or such underwriter, as the case may be, during such period of
time, not to exceed 180 days following the effective date of the registration statement filed by the Company with respect to such offering, as the Company or the underwriter may specify. 
 16. Interpretation. This Option is granted pursuant to the terms of the Plan, and shall in all respects be interpreted in accordance
therewith. The Administrator shall interpret and construe this Option and the Plan, and any action, decision, interpretation or determination made in good faith by the Administrator shall be final and binding on the Company and the Optionee. As used
in this Agreement, the term “Administrator” shall refer to the committee of the Board of Directors of the Company appointed to administer the Plan, and if no such committee has been appointed, the term Administrator shall mean the Board of
Directors. 
 17. Notices. Any notice, demand or request required or permitted to be given under this Agreement
shall be in writing and shall be deemed given when delivered personally or three (3) days after being deposited in the United States mail, as certified or registered mail, with postage prepaid, (or by such other method as the Administrator may
from time to time deem appropriate), and addressed, if to the Company, at its principal place of business, Attention: the Chief Financial Officer, and if to the Optionee, at his or her most recent address as shown in the employment or stock records
of the Company. 
 18. Governing Law. The validity, construction, interpretation, and effect of this Option shall be
governed by and determined in accordance with the laws of the State of California. 
  

 7 

 19. Severability. Should any provision or portion of this Agreement be held to be
unenforceable or invalid for any reason, the remaining provisions and portions of this Agreement shall be unaffected by such holding. 
 20. Attorneys’ Fees. If any party shall bring an action in law or equity against another to enforce or interpret any of the terms, covenants and provisions of this Agreement, the prevailing party in such action shall be
entitled to recover from the other party reasonable attorneys’ fees and any expert witness fees. 
 21. Counterparts. This
Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall be deemed one instrument. 
 22. California Corporate Securities Law. The sale of the shares that are the subject of this Agreement has not been qualified with the Commissioner of Corporations of the State of California and the
issuance of such shares or the payment or receipt of any part of the consideration therefor prior to such qualification is unlawful, unless the sale of such shares is exempt from such qualification by Section 25100, 25102 or 25105 of the
California Corporate Securities Law of l968, as amended. The rights of all parties to this Agreement are expressly conditioned upon such qualification being obtained, unless the sale is so exempt. 
  

 8 

 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first above written.
