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

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 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.

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; provided, however, that, in the discretion of the Administrator, any Option may be assigned or transferred in any manner which an “incentive stock
option” is permitted to be assigned or transferred under the Code.

 5.8 Rights as Shareholder. An Optionee or permitted transferee of an Option shall have no rights
or privileges as a shareholder 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. 
 ARTICLE 6. 
 RIGHTS TO PURCHASE 

 6.1 Nature of Right to Purchase. A Right to Purchase granted to an Offeree entitles the Offeree to purchase, for a Purchase Price
determined by the Administrator, 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. 
 6.2 Acceptance of Right to Purchase. An
Offeree shall have no rights with respect to the Restricted Stock subject to a Right to Purchase unless the Offeree shall have accepted the Right to Purchase within ten (10) days (or such longer or shorter period as the Administrator may
specify) following the grant of the Right to Purchase by making payment of the full Purchase Price to the Company in the manner set forth in Section 6.3 hereof and by executing and delivering to the Company a 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 upon acceptance of a Right to Purchase Restricted Stock 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 Offeree, which surrendered shares shall be valued at Fair Market Value as of the date of such exercise; (d) the Offeree’s promissory note in a form and on terms acceptable to the
Administrator; (e) the cancellation of indebtedness of the Company to the Offeree; (f) the waiver of compensation due or accrued to the Offeree 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 Shareholder. Upon
complying with the provisions of Section 6.2 hereof, an Offeree shall have the rights of a shareholder with respect to the Restricted Stock purchased pursuant to the Right to Purchase, including voting and dividend rights, subject to the terms,
restrictions and conditions as are set forth in the Stock Purchase Agreement. Unless the Administrator shall determine otherwise, certificates evidencing shares of Restricted Stock shall remain in the possession of the Company in accordance with the
terms of the Stock Purchase Agreement. 
 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 or by the Administrator. 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 

  

 6 

 
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, 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. 
 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. 
 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. 
 6.8 Nonassignability of Rights. No Right to Purchase shall be assignable or transferable except by will or the laws of descent and distribution or
as otherwise provided by the Administrator. 
 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

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 Options or Nonqualified Options shall be
granted and Rights to Purchase shall be offered, the number of shares to be represented by each Option and Right to Purchase and the consideration to be received by the Company upon the exercise thereof; (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 Right to Purchase under the Plan; (f) to correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any

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 

 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. 
 MERGERS AND OTHER REORGANIZATIONS 
 8.1 Mergers and Other Reorganizations. In the event that
the Company at any time proposes to enter into any transaction approved by the Board to sell substantially all of its assets or merge or consolidate with any other entity as a result of which either the Company is not the surviving corporation or
the Company is the surviving corporation and the ownership of the voting power of the Company’s capital stock changes by more than 50% as a result of such transaction, the Plan and all unexercised Options and Rights to Purchase shall terminate
upon the effective date of such transaction, unless provision is made in writing in connection with such transaction for the continuance of the Plan and for the assumption of outstanding Options and Rights to Purchase, or the substitution for such
Options and Rights to Purchase of new options and new rights to purchase of comparable value covering shares of a successor corporation, with appropriate adjustments as to the number and kind of shares and prices, in which event the Plan and such
Options and Rights to Purchase, or the new options and rights to purchase substituted therefor, shall continue in the manner and under the terms so provided. If such provision is not made in such transaction, then the Administrator shall cause
written notice of the proposed transaction to be given to all Participants not less than fifteen (15) days prior to the anticipated effective date of the proposed transaction and the time period relating to the exercise or realization of all
outstanding Options, Rights to Purchase and Restricted Stock shall accelerate immediately prior to the consummation of such transaction.*

1998 
 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. 
  

 8 

 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 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 interfere with 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.

 Exhibit 10.2

 THEROX, INCORPORATED

 INCENTIVE STOCK OPTION AGREEMENT 
 This Incentive Stock Option Agreement (the “Agreement”) is entered into as of                     
by and between THEROX, INCORPORATED, a Delaware corporation (the “Company”), and                      (the “Optionee”)
pursuant to the Company’s 1995 Stock Incentive Plan (the “Plan”). 
 R E C I T A L S : 
 A. Optionee is eligible to receive options under the Plan. 
 B. The Company desires to grant to Optionee, and Optionee desires to receive the grant of options under the Plan on the terms, provisions and conditions, and subject to the restrictions and agreements, hereinafter
provided. 
 NOW, THEREFORE, for good and valuable consideration, the parties agree as follows: 
 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 of the Common Stock
of the Company (the “Shares”) at a purchase price of          Cents ($0.        ) per share (the “Exercise Price”), subject to the
terms and conditions set forth herein and the provisions of the Plan. This Option is intended to constitute an “incentive stock option” within the meaning of the Plan.  
 2. Vesting of Option. The right to exercise this Option shall vest in
forty-eight equal cumulative monthly installments of one-forty-eighths (1/48th) of each share, commencing on
                    , and continuing until
                    , when this Option, unless sooner terminated, will have become exercisable as to all of the Shares issuable hereunder.
This Option shall be exercisable, in the manner set forth in Section 4 hereof, from time to time in whole or in part as to any and all vested installments, provided, however, that this Option shall not be exercised as to any fractional shares.
 
 No additional Shares shall vest after the date of termination of Optionee’s “Continuous Service” (as defined in
Section 3 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. 

3. Term of Option. Optionee’s right 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 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 or voluntary resignation; provided, however, that if Optionee dies during such three-month period the provisions of Section 3(e) below shall apply;

 (c) 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(e) below shall apply; 
 (d) 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); or 
 (e) 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(b) or 3(c) above, as the case may be. 
 As used herein, 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, or (iii) so long as Optionee is engaged as a consultant or service provider to the Company or other corporation referred to in clause (i) above. 
 4. Exercise of Option. On or after the vesting of any portion of this Option in accordance with Section 2 above, and until termination of this Option in accordance with Section 3 above,
the portion of this Option which has vested may be exercised in whole or in part by the Optionee (or, after Optionee’s death, by the successor 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); 
 (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 

  

 2 

 
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 
 (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 Optionee’s death, and provided Optionee’s rights hereunder shall have vested pursuant to Section 2 hereof,
Optionee’s legal representative, Optionee’s 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 1933, as amended (the “Act”), on the basis of certain
exemptions from such registration requirement. Accordingly, Optionee agrees that Optionee’s exercise of the Option may be expressly conditioned upon Optionee’s 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 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 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. Restrictive Legends. Optionee hereby acknowledges that federal securities
laws and the securities laws of the state in which Optionee 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.

 8. 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. 
 9. 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 9, 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) Optionee’s bona fide intention to sell or otherwise transfer such Shares, (ii) the name and address of the proposed purchaser(s), (iii) the number of Shares the Optionee proposes to sell (the “Offered
Shares”), (iv) the price for which Optionee 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 a check (or, at the discretion of the Company, such other form of consideration set forth in the Offer Notice) in the amount of the purchase price of the Offered Shares to be
purchased pursuant to this Section 9, 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. 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 9. 
 (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 9, 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 9. 
  

 4 

 (d) Any Successor of Optionee pursuant to Section 5 hereof, and any transferee of the Shares
pursuant to this Section 9, 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 9. 
 (e) 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 AGAINST TRANSFER, INCLUDING A RIGHT OF FIRST REFUSAL IN
FAVOR OF THE COMPANY, AS SET FORTH IN A STOCK OPTION AGREEMENT DATED                     . 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 THE COMPANY.” 
 (f) The rights
provided the Company and its nominee(s) under this Section 9 shall terminate upon the closing of an underwritten public offering of shares of the Company’s Common Stock pursuant to an effective registration statement under the Securities
Act of 1933, as amended (the “Securities Act”). 
 10. Repurchase Option. 
 (a) In the event Optionee ceases Continuous Service with the Company for any reason (the “Termination”), any Shares acquired or which may
thereafter be acquired pursuant to the exercise of this Option (the “Purchased Shares”) (whether held by Optionee or one or more of Optionee’s transferees) will be subject to repurchase by the Company (or its nominee(s)) pursuant to
the terms and conditions set forth in this Section 10 (the “Repurchase Option”). 
 (b) The purchase price for each Purchased
Share will be the “Fair Market Value” (as defined below) for such share as determined on the date of Termination (the “Repurchase Price”). 
 (c) The Company’s board of directors (the “Board”) (or its nominee(s)) may elect to purchase all or any portion of the Purchased Shares by delivering written notice (the “Repurchase Notice”)
to the holder or holders of the Purchased Shares within 120 days after the Termination. The Repurchase Notice will set forth the number of Purchased Shares to be acquired from Optionee, the aggregate consideration to be paid for such shares and the
time and place for the closing of the transaction. The number of Purchased Shares to be repurchased shall first be satisfied to the extent possible from the Purchased Shares held by Optionee at the time of delivery of the Repurchase Notice. If the
number of Purchased Shares then held by Optionee is less than the total number of Purchased Shares which the Company (or its nominee(s)) has elected to purchase, the Company (or its nominee(s)) shall purchase the remaining Purchased Shares elected
to be purchased from the other holder(s) of Purchased Shares under this Agreement, pro rata according to the number of Purchased Shares held by such other holder(s) at the time of delivery of such Repurchase Notice (determined as nearly as
practicable to the nearest share). 
  

 5 

 (d) The closing of the purchase of the Purchased Shares pursuant to the Repurchase Option shall take
place on the date designated by the Company (or its nominee(s)) in the Repurchase Notice, which date shall not be more than one (1) month nor less than five (5) days after the delivery of such notice (the “Repurchase Date”). The
Company may, at its option, pay for the Purchased Shares to be purchased pursuant to the Repurchase Option either (i) in one lump sum payment by delivery of a check or wire transfer on the Repurchase Date in an amount equal to the Repurchase
Price, or (ii) by delivery on the Repurchase Date of (A) a check or wire transfer in an amount equal to the sum of the aggregate original cost of the Purchased Shares to be repurchased, in any event not exceeding in the aggregate the
Repurchase Price (the “Cash Repurchase Payment”), and (B) a promissory note of the Company in a principal amount equal to the Repurchase Price minus the Cash Repurchase Payment, bearing interest at the rate of nine percent
(9%) per annum non-compounded commencing on the Repurchase Date and providing for payment of the principal amount, plus accrued interest, in twelve (12) installments on the last day of each calendar month for the next twelve
(12) months following the Repurchase Date. In addition, the Company may pay the Repurchase Price for such shares by offsetting amounts outstanding under any bona fide debts owed by Optionee to the Company. The Company (or its nominee(s)) will
be entitled to receive customary representations and warranties from the sellers regarding such sale and to require all sellers’ signatures be guaranteed. 
 (e) Notwithstanding anything to the contrary contained in this Agreement, all repurchases of Purchased Shares by the Company shall be subject to applicable restrictions contained in the Delaware General Corporation
Law and in the Company’s and its subsidiaries’ debt and equity financing agreements. If any such restrictions prohibit the repurchase of Purchased Shares hereunder which the Company has otherwise elected to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions; provided, however, that, notwithstanding such restrictions, the Company shall deliver the Repurchase Notice as provided in paragraph 10(c) above, and shall remain bound by the
terms of such Repurchase Notice until such time as the Purchased Shares are actually purchased by the Company pursuant to such notice. 
 (f)
For purposes of this Section 10, the Fair Market Value will be the fair value of the Common Stock determined in good faith by the Board. 
 (g) The rights provided the Company under this Section 10 shall terminate upon the closing of an underwritten public offering of shares of the Company’s Common Stock pursuant to an effective registration statement under the
Securities Act. 
 11. 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 4.2 of the Plan.  
  

 6 

 12. Mergers and Other Reorganizations. In the event that the Company at any time
proposes to enter into any transaction approved by the Board to sell substantially all of its assets or merge or consolidate with any other entity as a result of which either the Company is not the surviving corporation or the Company is the
surviving corporation and the ownership of the voting power of the Company’s capital stock changes by more than 50% as a result of such transaction, or in the event of a “Recommended Share Purchase Offer” (as defined below), this
Option shall terminate upon the effective date of such transaction unless provision is made in writing in connection with such transaction for the continuance or assumption of this Option or the substitution for this Option of a new option of
comparable value covering shares of a successor corporation, with appropriate adjustments as to the number and kind of shares and the Exercise Price, in which event this Option or the new option substituted therefor shall continue in the manner and
under the terms so provided. If such provision is not made in such transaction, then the Administrator shall cause written notice of the proposed transaction to be given to Optionee not less than ten (10) days prior to the anticipated effective
date of the proposed transaction, and the Optionee shall have the right to exercise the Option in respect to any or all of the vested and unvested Shares immediately prior to the consummation of such transaction. For purposes of this
Section 12, a “Recommended Share Purchase Offer” shall be a transaction in which an offer is made to purchase outstanding securities of the Company constituting more than 50% of the voting power of the Company’s capital stock,
which offer is recommended to the Company’s securityholders by the Company’s Board. 
 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, subject to any other written employment agreement to
which the Company and Optionee may be a party.  
 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 the date of the issuance of a stock certificate or certificates to him or her for such
Shares, notwithstanding the exercise of this Option.  
 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 

  

 7 

 
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, and addressed, if to the Company, at its principal place of business, Attention: the Chief Financial Officer, and if to the Optionee, at Optionee’s most recent address as shown in the employment or stock records of the Company.

 18. Annual and Other Periodic Reports. During the term of this Agreement, the Company will furnish to the
Optionee copies of all annual and other periodic financial and informational reports that the Company distributes generally to its shareholders.  
 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. 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.  
 21.
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 1968, as amended. The rights of all parties to this Agreement are expressly conditioned upon such qualification being obtained, unless the sale is so exempt.  
 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first above written.
