 5. ELIGIBILITY

 5.1 ELIGIBLE OPTIONEES. Incentive Options may be granted only to employees of the Company or its Parent or Subsidiaries,
including members of the Board who are also employees of the Company or a Parent or Subsidiary; provided that, for any period in which the Company is taxed as an “S” corporation for income tax purposes, an individual shall be
eligible for the grant of an Option hereunder only if (and for so long as) such individual is eligible under Section 1361 of the Code to be a shareholder in an “S” corporation without occasioning a revocation of the Company’s
“S” corporation election. If the holder of an Option granted hereunder is so eligible to be a shareholder in an “S” corporation at the time the Option is granted but thereafter loses such eligibility, then such Option may not be
exercised unless and until such eligibility is restored. Nonqualified Options may be granted to officers or other 

  
 4 








 
employees of the Company or its Parent or Subsidiaries, to members of the Board or the board of directors of a Parent or any Subsidiary whether or not employees of the Company or such Parent or
Subsidiary, and to other individuals providing services to the Company or its Parent or Subsidiaries. 
 5.2 LIMITATIONS ON 10%
STOCKHOLDERS. No Option shall be granted to an individual who, at the time the Option is granted, owns (including ownership attributed pursuant to Section 424(d) of the Code) more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or a Parent or Subsidiary of the Company (a “greater-than-10% stockholder”), unless such Option provides that (i) the purchase price per share shall not be less than 110% of the Fair Market
Value of the Common Stock at the time such Incentive Option is granted, and (ii) if such Option is an Incentive Option, then such Option shall not be exercisable to any extent after the expiration of five (5) years from the date on which
it is granted. 
 5.3 LIMITATION ON EXERCISABLE OPTIONS. The aggregate Fair Market Value (determined at the time the Incentive Option
is granted) of the Common Stock with respect to which Incentive Options are exercisable for the first time by any person during any calendar year under the Plan and under any other Option plan of the Company (or a parent or subsidiary as defined in
Section 424 of the Code) shall not exceed $100,000. Any Option granted in excess of the foregoing limitation shall be specifically designated as being a Nonqualified Option. The first sentence of this Section 5.3 shall be applied by
reference to the Fair Market Value of Common Stock as of the time the Option is granted. 
 6. TERMS OF OPTION AGREEMENTS 

6.1 MANDATORY TERMS. Each Option agreement shall contain such provisions as the Board or the Committee from time to time determines to
be appropriate. Option agreements need not be identical, but each Option agreement by appropriate language shall include the substance of all of the following provisions: 

(a) EXPIRATION. Notwithstanding any other provision of the Plan or of any Option agreement, each Option shall expire on the date
specified in the Option agreement, which date shall not be later than the tenth anniversary of the date on which the Option was granted (fifth anniversary in the case of an Incentive Option granted to a greater-than-10% stockholder). 

(b) EXERCISE; VESTING. Each Option shall be exercisable in full or in installments (which need not be equal) and at such times as
designated by the Board or the Committee. To the extent not exercised, installments shall accumulate and be exercisable, in whole or in part, at any time after becoming exercisable, but not later than the date the Option expires. Unless the Board or
Committee determines otherwise with respect to any Option granted or any shares of Restricted Stock issued hereunder, the Holder of each Option shall become vested in such Option and each Restricted Stockholder shall become vested in shares of
Restricted Stock as follows: (i) twenty-five percent (25%) of the shares after twelve (12) consecutive months of employment with the Company, and (ii) thereafter, one-thirty-sixth
(1/36th) of the remainder of the shares for each complete subsequent month of continuous 

  
 5 








 
employment with the Company, provided that any other vesting scheduled approved by the Board or Committee for grants to any person other than an officer or director of or consultant to the
Company must provide for a vesting rate of at least twenty percent (20%) per year over a period of not more than five (5) years. 

(c) PURCHASE PRICE. The purchase price per share of the Common Stock under each Incentive Option shall be not less than one hundred
percent (100%) of the Fair Market Value of the Common Stock on the date the Option is granted (110% of the Fair Market Value in the case of a greater-than-10% stockholder). The price at which shares may be purchased pursuant to Nonqualified
Options shall be specified by the Board or the Committee at the time the Option is granted, and may be less than, equal to or greater than the Fair Market Value of the shares of Common Stock on the date such Nonqualified Option is granted, but shall
not be less than one hundred percent (100%) of the Fair Market Value of the Common Stock on the date the Option is granted. 
 (d)
TRANSFERABILITY OF OPTIONS. Options granted under the Plan and the rights and privileges conferred thereby may not be transferred, assigned, pledged or hypothecated in any manner (whether by operation of law or otherwise) other than by will or
by applicable laws of descent and distribution, and shall not be subject to execution, attachment or similar process. Upon any attempt to so transfer, assign, pledge, hypothecate or otherwise dispose of any Option under the Plan (or any right or
privilege conferred hereby), contrary to the provisions of the Plan, or upon any attempted levy or any attachment or similar process upon the rights and privileges conferred hereby, such Option shall thereupon terminate and become null and void.

 (e) TERMINATION OF EMPLOYMENT OR DEATH OR DISABILITY OF OPTIONEE. Except as otherwise expressly provided in the terms and
conditions of the Option granted to an Optionee, Options granted hereunder shall terminate on the earliest to occur of (i) the date of expiration thereof; (ii) if the Holder is employed by the Company and such employment is terminated by
the Company for “Cause”, as hereinafter defined, on the date of such termination; or (iii) if the Holder is employed by the Company and such employment is terminated for any reason other than death, Disability or for Cause as
aforesaid, on the earlier of the date of expiration thereof or ninety (90) days following the date of such termination. 
 (i)
Until the date on which the Option so expires or terminates, the Holder may exercise that portion of his Option which is exercisable at the time of termination of such relationship. An employment relationship between the Company and the Holder
shall be deemed to exist during any period during which the Holder is employed by the Company or by a Parent or any Subsidiary. Whether authorized leave of absence or absence on military government service shall constitute termination of the
employment relationship between the Company and the Holder shall be determined by the Board or the Committee at the time thereof. For purposes of this Section 6.1(0, the term “Cause” shall mean (a) any material
breach by the Holder of any agreement to which the Holder and the Company are both parties; (b) any act (other than retirement) or omission to act by the Holder which may have a material and adverse effect on the Company’s business or on
the Optionee’s ability to perform services for the Company, including, without limitation, the commission of any crime (other than minor traffic 

  
 6 








 
violations), (c) any material misconduct or material neglect of duties by the Holder in connection with the business or affairs of the Company or any Subsidiary or affiliate of the Company,
or (d) any other act or omission constituting “Cause” for termination of Holder’s employment or engagement by the Company under any employment or other service agreement between such Holder and the Company. 

(ii) In the event of the death or Disability of any Holder while in an employment or other relationship with the Company and before
the date of expiration of such Option, such Option shall terminate on the earlier of such date of expiration or six (6) months following the date of such death or Disability. After the death of the Optionee, his executor, Board or Committee or
any person or persons to whom his Option may be transferred by will or by laws of descent and distribution, shall have the right, at any time prior to such termination, to exercise the Option to the extent the Holder was entitled to exercise such
Option as of the date of his death. 
 (f) RIGHTS OF OPTIONEES. No Holder shall be deemed for any purpose to be the owner of any
shares of Common Stock subject to any Option unless and until (i) the Option shall have been exercised with respect to such shares pursuant to the terms thereof; and (ii) the Company shall have issued and delivered a certificate
representing such shares. Thereupon, the Holder shall have full voting, dividend and other ownership rights with respect to such shares of Common Stock, subject to any agreements entered into by the Holder in connection with the Optionees exercise
of the Option and acquisition of the stock. 
 6.2 CERTAIN OPTIONAL TERMS. The Board or the Committee may in its discretion provide,
upon the grant of any Option hereunder, that the stock shall be subject to the terms of a repurchase or shareholders’ agreement including any and all commercially reasonable terms, such as, without limitation, that the Company shall have the
right from time to time to repurchase all or any number of shares purchased upon exercise of such Option. 
 (a) REPURCHASE PRICE.
The repurchase price per share payable by the Company shall be determined as follows. 
 (i) Price Generally. Such repurchase
price for the shares shall be either: 
 (A) Not less than the Fair Market Value of the shares to be repurchased upon the date of
termination of employment or other service engagement, and the right to repurchase (i) must be exercised for cash or cancellation of purchase money indebtedness for the stock within ninety (90) days of termination of employment or other
service engagement (or, in the case of securities issued upon exercise of Options after the date of termination, within ninety (90) days after the date of exercise), and (ii) must lapse on the first date on which the Company’s shares
of Common Stock become listed on an established national stock exchange or NASDAQ. 
 (B) The original purchase price for such shares,
provided that the right to repurchase at the original purchase price lapses at the rate of at least twenty percent (20%) per year over a period of not more than five (5) years from the date the Option is granted


  
 7 








 
(without regarding to the date on which the Option is exercised or becomes exercisable) and the right to repurchase must be exercised for cash or cancellation of indebtedness for the securities
within ninety (90) days of termination of employment or other service engagement (or in the case of securities issued upon exercise of options after the date of termination of employment or other service engagement, within ninety (90) days
after the date of the exercise). 
 (ii) Officers, Directors, Managers, and Consultants. Notwithstanding the provisions of
Section 6.2(a)(i), above, the securities held by an officer, director, manager, or consultant of the Company may be subject to additional or greater restrictions. 

(iii) Right of First Refusal. The Board or the Committee may also provide that the Company shall have a right of first refusal
with respect to the transfer or proposed transfer of any shares purchased upon exercise of an Option granted hereunder. In the event the Board or the Committee shall grant Options subject to the Company’s repurchase rights or rights of first
refusal, the certificate or certificates representing the shares purchased pursuant to the exercise of such Option shall carry a legend satisfactory to counsel for the Company referring to such rights. 

(b) FORM OF OPTION AGREEMENT. Notwithstanding the foregoing, the form of Stock Option Agreement attached to this Plan at EXHIBIT A is
hereby approved for use with stockholders with respect to shares issued under this Plan. Such form may be used under this Plan by the Board, the Committee, and the officers of the Company, in their discretion, without any further approval from the
stockholders, the Board or the Committee. 
 7. AWARD OF RESTRICTED STOCK 

7.1 AWARD OF RESTRICTED STOCK. The Board or Committee from time to time, in its absolute discretion, may (a) award Restricted Stock
(in lieu of Options) to employees of, consultants to, and directors of the Company, and such other persons as the Board or Committee may select, and (b) permit Holders of Options to exercise such Options prior to full vesting therein and hold
the Common Stock issued upon exercise of the Option as Restricted Stock. In either such event, the owner of such Restricted Stock shall hold such stock subject to such vesting schedule as the Board or Committee may impose or such vesting schedule to
which the Option was subject, as determined in the discretion of the Board or Committee. The purchase price of such shares of Restricted Stock shall not be less than eighty-five percent (85%) of the Fair Market Value of the shares of Restricted
Stock (or 100% of such Fair Market Value, if the recipient of such shares of Restricted Stock is a “greater-than-10% stockholder,” as such term is defined in Section 5.2, above) as of the time the award of such shares of
Restricted Stock is approved by the Board. Any unvested shares of Restricted Stock that are repurchased by the Company pursuant to this Section 7 shall be deemed to be restored to the Plan in a manner consistent with
Section 4.3, above. 
 7.2 RESTRICTED STOCK REPURCHASE AGREEMENT. Restricted Stock shall be issued only pursuant to a
Restricted Stock Repurchase Agreement, which shall be executed by the Restricted Stockholder and the Company and which shall contain such terms and conditions as the Board or Committee shall determine consistent with this Plan, including such

 7.3 RIGHTS AS STOCKHOLDERS. Upon delivery of the shares of Restricted Stock to the
Restricted Stockholder or to the escrow holder pursuant to Section 7.8, below, the Restricted Stockholder shall have, unless otherwise provided by the Board or Committee, all the rights of a stockholder with respect to said shares,
subject to the restrictions in the Restricted Stock Repurchase Agreement, including the right to receive all dividends and other distributions (other than stock dividends, which shall be paid to the escrow holder for the benefit of the Restricted
Stockholder) paid or made with respect to the Restricted Stock. 
 7.4 RESTRICTION ON TRANSFER: VESTING. Notwithstanding anything in
this Plan or any Restricted Stock Repurchase Agreement to the contrary, no Restricted Stockholders may sell or otherwise transfer, whether or not for value, any of the Restricted Stock prior to the date on which the Restricted Stockholder is vested
therein. 
 7.5 ADDITIONAL RESTRICTIONS. All shares of Restricted Stock issued under this Plan (including any shares of Common Stock
and other securities issued with respect to the shares of Restricted Stock as a result of stock dividends, stock splits or similar changes in the capital structure of the Company) shall be subject to such restrictions as the Board or Committee shall
provide, which restrictions may include, without limitation, restrictions concerning voting rights, transferability of the Restricted Stock and restrictions based on duration of employment with the Company, Company performance and individual
performance; provided that the Board or Committee may, on such terms and conditions as it may determine to be appropriate, remove any or all of such restrictions. Restricted Stock may not be sold or encumbered until all applicable restrictions have
terminated or expire. The restrictions, if any, imposed by the Board or Committee or the Board under this Section 7 need not be identical for all shares of Restricted Stock and the imposition of any restrictions with respect to any
Restricted Stock shall not require the imposition of the same or any other restrictions with respect to any other Restricted Stock. 

7.6 REPURCHASE OF UNVESTED RESTRICTED STOCK. Each Restricted Stock Repurchase Agreement shall provide that the Company shall have the
right to repurchase from the Restricted Stockholder the unvested Restricted Stock upon a termination of employment, termination of directorship or termination of a consulting arrangement, as applicable, at a price per share equal to the purchase
price paid by the Restricted Stockholder for such Restricted Stock, provided that the right to repurchase at the original purchase price lapses at the rate of at least twenty percent (20%) per year over a period of not more than five
(5) years from the date the shares of Restricted Stock are issued, and the right to repurchase must be exercised for cash or cancellation of purchase-money indebtedness for the securities within ninety (90) days of termination of
employment. 
 7.7 RIGHT OF FIRST REFUSAL. In the discretion of the Board or Committee, the Restricted Stock Repurchase Agreement may
provide that the Company shall have a right of first refusal with respect to the Restricted Stock and a right to repurchase the vested Restricted Stock upon a termination of the Restricted Stockholder’s employment with the Company, the
termination of the Restricted Stockholder’s consulting arrangement with the Company, the termination of the Restricted Stockholder’s service on the Company’s Board, or such other events as the Board or Committee may deem appropriate.


  
 9 








 7.8 ESCROW. The Secretary of the Company or such other escrow holder as the Board or
Committee may appoint shall retain physical custody of each certificate representing Restricted Stock until all of the restrictions imposed on the Restricted Stock expire or have been removed. 

7.9 LEGEND. The Board or Committee shall cause a legend or legends to be placed on certificates representing shares of Restricted Stock
that are subject to restrictions under Restricted Stock Repurchase Agreements, which legend or legends shall make appropriate reference to the applicable restrictions. 

8. METHOD OF EXERCISE; PAYMENT OF PURCHASE PRICE 

8.1 MEANS OF EXERCISE. Any Option granted under the Plan may be exercised by the Holder by delivering to the Company on any business day
a written notice specifying the number of shares of Common Stock the Holder then desires to purchase and specifying the address to which the certificates for such shares are to be mailed (the “Notice”). The Notice shall be
accompanied by payment for such shares, any required payment of withholding taxes, and such documents, including without limitation an investment letter and a repurchase or shareholder’s agreement duly executed by the Holder relating, among
other things, to restrictions on transfer rights of first refusal and Company buy-back rights (if applicable), as may reasonably be required or requested by the Company. 

8.2 PAYMENT OF EXERCISE PRICE. The consideration for such shares shall be paid, with the approval of the Board or Committee, either:

 (a) In cash, certified or bank check or postal money order payable to the order of the Company for an amount equal to the sum of
(x) the Exercise Price of such shares, plus (y) the amount, if any, required to fund withholding taxes due with respect to such exercise, as contemplated by Section 12.3, below. If as of the date of Holder’s exercise of
the Option the Company then is sponsoring a cashless exercise program through one or more approved brokers, then upon notification by Holder the Company will tender to a Company-approved broker any cash to be delivered under the foregoing clause
“(x)” may be provided with the proceeds of any Option Shares which Holder elects to cause to be sold in connection with the exercise of the Option, the date on which the Company receives the proceeds from the sale of those shares shall be
deemed to be the date on which the Option is exercised, and any applicable income, withholding and other taxes shall be calculated based upon the selling price of the Option Shares sold by the Company-approved broker pursuant to such cashless
exercise. 
 (b) With one or more share certificates for a number of shares of outstanding Company Common Stock having a Fair Market
Value on the date of tender equal to the sum of (vv) the Exercise Price of such shares, plus (x) the amount, if any, required to fund withholding taxes due with respect to such exercise, as contemplated by Section 12.3,
below; provided that the Company shall not be obligated to accept the transfer of any shares of Common Stock in payment of the exercise price unless such transfer satisfies all of the provisions of Rule 16b-3 then applicable to the Company.


  
 10 








 (c) If authorized by the applicable Option agreement, by a “net exercise” under
which Holder relinquishes the right to acquire a number of shares of Common Stock issuable upon exercise of the Option (but not in excess of the vested portion thereof) having a net Fair Market Value (i.e., net of the Exercise Price therefore) equal
to the amount of the aggregate Exercise Price of the shares for which the Option is being exercised. 
 8.3 DELIVERY OF CERTIFICATE.
Promptly after receipt of such written notification and payment, the Company shall deliver to the Holder or other appropriate person certificates for the number of shares with respect to which such Option has been so exercised, issued in the
Optionee’s name; provided, however, that such delivery shall be deemed effected for all purposes when the Company or a stock transfer agent of the Company shall have deposited such certificates in the United States mail, addressed to the
Holder or other appropriate person, at the address specified pursuant to Section 8.1 or another appropriate address designated by the Holder. 

9. ADJUSTMENT UPON CHANGES IN CAPITALIZATION 

9.1 NO EFFECT OF OPTIONS UPON CERTAIN CORPORATE TRANSACTIONS. The existence of outstanding Options shall not affect in any way the right
or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or
any issue of Common Stock, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any
part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 
 9.2 STOCK
DIVIDENDS, RECAPITALIZATIONS, ETC. If the Company effects a subdivision or consolidation of shares or other capital readjustment, the payment of a stock dividend, or other increase or reduction of the number of shares of the Common Stock
outstanding, without receiving compensation therefor in money, services or property, then: (a) the number, class and per share price of shares of stock subject to outstanding Options hereunder shall be appropriately adjusted in such a manner as
to entitle a Holder to receive upon exercise of an Option, for the same aggregate cash consideration, the same total number and class of shares that the owner of an equal number of outstanding shares of Common Stock would own as a result of the
event requiring the adjustment; and (b) the number and class of shares with respect to which Options may be granted under the Plan shall be adjusted by substituting for the total number of shares of Common Stock then reserved for issuance under
the Plan that number and class of shares of stock that the owner of an equal number of outstanding shares of Common Stock would own as a result of the event requiring the adjustment. 

9.3 DETERMINATION OF ADJUSTMENTS. Adjustments under this Section 9 shall be determined by the Board or the Committee and
such determinations shall be conclusive. The Board or the Committee shall have the discretion and power in any such event to determine and to make effective provision for acceleration of the time or times at which any Option or portion thereof shall
become exercisable. No fractional shares of Common Stock shall be issued under the Plan on account of any adjustment specified above. 

  
 11 








 9.4 NO ADJUSTMENT IN CERTAIN CASES. Except as hereinbefore expressly provided, the issue
by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property or for labor or services, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or
upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock then subject
to outstanding Options. 
 10. EFFECT OF CERTAIN TRANSACTIONS. If, while unexercised Options or unvested shares of Restricted Stock remain
outstanding under the Plan, the Company is a party to a reorganization or merger with one or more other corporations, whether or not the Company is the surviving or resulting corporation, or if the Company consolidates with or into one or more other
corporations, or if the Company is liquidated, or if there is a sale or other disposition of substantially all of the Company’s capital stock or assets to a third party or parties (each hereinafter referred to as a
“Transaction”), then: 
 10.1 OPTION OUTSTANDING. Subject to the provisions of Section 10.2, below, as
of the effective date of such Transaction, all Options (and the vested portion of each Option) shall terminate unless assumed by the acquiring or surviving corporation or exercised prior to the closing of the Transaction. 

10.2 PERMISSIVE ACCELERATION. The Board may (a) accelerate the time for exercise of any or all portion of any unvested,
unexercised and unexpired Options, effective as of a date prior to the effective date of such Transaction; provided that (i) notice of acceleration shall be given to each Holder of an Option to which such acceleration is to
apply; (ii) each Holder of an Option shall have the right to exercise such Option in part or in full prior to the effective date of such Transaction; and (iii) to the extent not so exercised, all of such Options shall be canceled prior to
or as of such effective date (unless assumed by the acquiring or surviving Corporation), and/or (b) provide for a cash payment to the holders of vested Options in exchange for the cancellation thereof, equal to the excess of the fair market
value (as reasonably determined by the Board) of the shares subject to such Options (to the extent then vested) over the exercise price thereof. 
 11.
NON-EXCLUSIVITY OF THE PLAN; NON-UNIFORM DETERMINATIONS. Neither the adoption of the Plan by the Board nor the approval of the Plan by the stockholders of the Company shall be construed as creating any limitations on the power of the Board to
adopt such other incentive arrangements as it may deem desirable, including without limitation the granting of stock Options otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases. The
Board’s or Committee’s determinations under the Plan need not be uniform and may be made by it selectively among persons who receive or are eligible to receive Options under the Plan (whether or not such persons are similarly situated).
Without limiting the generality of the foregoing, the Board or the Committee shall be entitled, among other things, to make non-uniform and selective determinations, and to enter into non-uniform and selective Option agreements, as to (i) the
persons to receive Options under the Plan, (ii) the terms and provisions of Options, (iii) the exercise by the Board or the Committee of its discretion in respect of the exercise of Options pursuant to the terms of the Plan, and
(iv) the treatment of leaves of absence pursuant to Section 6.1(e), above.

12.3 WITHHOLDING. Whenever under the Plan shares are to be delivered upon exercise of an Option, the Company shall be entitled to
require as a condition of delivery that the Holder remit an amount sufficient to satisfy all federal, state and other governmental withholding tax requirements related thereto. If the Company permits exercise of an Option hereunder and thereafter
discovers that withholding taxes are due from the Option holder in an amount in excess of the amount theretofore deposited with the Company by such Holder, then the Company shall be entitled to withhold all stock certificates for the shares
underlying such Option until such Option holder deposits such amount with the Company.

swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of
Common Stock or other securities, in cash, or otherwise.

before termination or amendment of the Plan shall not be altered or impaired by such termination or amendment except with the consent of the Optionee. 

14.3 NO ASSURANCES OF EMPLOYMENT. Neither the adoption of this Plan, the granting of any Option hereunder, nor the execution of an
Option agreement with any Holder is intended or shall be construed as either (a) conferring on any individual any right to remain employed by the Company for any specified term, or (b) limiting in any way the right, power and authority of
the Company to terminate the employment or other service engagement of such person at any time either with or without cause. 
 14.4
