2. Definitions. The following definitions shall apply as used herein and in the individual Award Agreements except as defined otherwise

then-effective written agreement and definition, the Grantee’s: (i) performance of any act or failure to perform any act in bad faith and to the detriment of the Company or a Related Entity; (ii) dishonesty, intentional misconduct or material
breach of any agreement with the Company or a Related Entity; or (iii) commission of a crime involving dishonesty, breach of trust, or physical or emotional harm to any person, in each case as determined by the Administrator; provided, however,
that with regard to any agreement that defines “Cause” as occurring upon the consummation of, or in connection with, a Corporate Transaction or a Change in Control, such definition of “Cause” shall not apply until a Corporate
Transaction or a Change in Control is actually consummated. 
 (j) “Change in Control” means a change in ownership or
control of the Company effected through either of the following types of transactions: 
 (i) the direct or indirect acquisition by any
person or related group of persons (other than an acquisition from or by the Company or by a Company-sponsored employee benefit plan or by a person that directly or indirectly controls, is controlled by, or is under common control with, the Company)
of beneficial ownership (within the meaning of Rule 13d-3 of the Exchange Act) of securities possessing more than fifty percent (50%) of the total combined voting power of the Company’s outstanding

of at least twelve (12) months or (ii) have been Board members for less than twelve (12) months and were elected or nominated for election as Board members by at least a majority of the Board members described in clause (i) who

 (q) “Continuous Service” means that the provision of services to the Company or
a Related Entity by an Employee, Director or Consultant in any capacity has not been interrupted or terminated. In jurisdictions requiring notice in advance of an effective termination as an Employee, Director or Consultant, Continuous Service shall
be deemed terminated upon the actual cessation of providing services to the Company or a Related Entity notwithstanding any required notice period that must be fulfilled before a termination as an Employee, Director or Consultant can be effective
under Applicable Laws. A Grantee’s Continuous Service shall be deemed to have terminated either upon an actual termination of Continuous Service or upon the entity to which the Grantee provides services ceasing to be a Related Entity.
Continuous Service shall not be considered interrupted in the case of (i) any approved leave of absence, (ii) transfers of an Employee, Director or Consultant among the Company, any Related Entity, or any successor, in any capacity, or
(iii) any change in status of an Employee, Director or Consultant as long as the individual remains in the service of the Company or a Related Entity in any capacity (except as otherwise provided in the Award Agreement). Notwithstanding the
foregoing, except as otherwise determined by the Administrator, in the event of any spin-off of a Related Entity, service as an Employee, Director or Consultant for such Related Entity following such spin-off shall be deemed to be Continuous Service for purposes of the Plan and any Award under the Plan. An approved leave of absence shall include sick leave, military leave, or any other authorized personal leave.
For purposes of each Incentive Stock Option granted under the Plan, if such leave exceeds three (3) months, and reemployment upon expiration of such leave is not guaranteed by statute or contract, then the Incentive Stock Option shall be
treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day following the expiration of such three (3) month period. 

(r) “Corporate Transaction” means any of the following transactions, provided, however, that the Administrator shall
determine under parts (iv) and (v) whether multiple transactions are related, and its determination shall be final, binding and conclusive: 

(i) a merger or consolidation in which the Company is not the surviving entity, except for a transaction the principal purpose of which is to
change the state in which the Company is incorporated; 
 (ii) the sale, transfer or other disposition of all or substantially all of the
assets of the Company;

(iv) any reverse merger or series of related transactions culminating in a reverse merger (including, but not limited to, a tender offer
followed by a reverse merger) in which the Company is the surviving entity but (A) the shares of Common Stock outstanding immediately prior to such merger are converted or exchanged by virtue of the merger into other property, whether in the
form of securities, cash or otherwise, or (B) in which securities possessing more than fifty percent (50%) of the total combined voting power of the Company’s outstanding securities are transferred to a person or persons different from
those who held such securities immediately prior to such merger or the initial transaction culminating in such merger, but excluding any such transaction or series of related transactions that the Administrator determines shall not be a Corporate
Transaction; or 
 (v) acquisition in a single or series of related transactions by any person or related group of persons (other than the
Company or by a Company-sponsored employee benefit plan) of beneficial ownership (within the meaning of Rule 13d-3 of the Exchange Act) of securities possessing more than fifty percent (50%) of the total
combined voting power of the Company’s outstanding securities but excluding any such transaction or series of related transactions that the Administrator determines shall not be a Corporate Transaction.

the Company or the Related Entity to which the Grantee provides services regardless of whether the Grantee is covered by such policy. If the Company or the Related Entity to which the Grantee provides service does not have a long-term disability
plan in place, “Disability” means that a Grantee is unable to carry out the responsibilities and functions of the position held by the Grantee by reason of any medically determinable physical or mental impairment for a period of not less
than ninety (90) consecutive days. A Grantee will not be considered to have incurred a Disability unless he or she furnishes proof of such impairment sufficient to satisfy the Administrator in its discretion.

to Common Stock, provided that no such right may be granted with respect to Options or SARs. Dividend Equivalent Rights granted in connection with a Restricted Stock Unit that vests based on the attainment of performance criteria shall be subject to

the employ of the Company or any Related Entity, subject to the control and direction of the Company or any Related Entity as to both the work to be performed and the manner and method of performance. The payment of a director’s fee by the

closing bid, if no sales were reported) as quoted on the principal exchange or system on which the Common Stock is listed (as determined by the Administrator) on the date of determination (or, if no closing sales price or closing bid was reported on

 (ii) If the Common Stock is regularly quoted on an automated quotation system (including the OTC
Bulletin Board) or by a recognized securities dealer, its Fair Market Value shall be the closing sales price for such stock as quoted on such system or by such securities dealer on the date of determination, but if selling prices are not reported,
the Fair Market Value of a share of Common Stock shall be the mean between the high bid and low asked prices for the Common Stock on the date of determination (or, if no such prices were reported on that date, on the last date such prices were
reported), as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or 
 (iii) In the
absence of an established market for the Common Stock of the type described in (i) and (ii), above, the Fair Market Value thereof shall be determined by the Administrator in good faith. 

(z) “Good Reason” means, “Good Reason” as such term (or word of like import) is expressly defined in a
then-effective written agreement between the Grantee and the Company or a Related Entity, or in the absence of such then-effective written agreement and definition, any of the following events or conditions unless consented to by the Grantee (and

event or condition): 
 (i) a change in the Grantee’s responsibilities or duties which represents a material and substantial
diminution in the Grantee’s responsibilities or duties; 
 (ii) a material reduction in the Grantee’s base salary; provided that
an across-the-board reduction in the salary level of substantially all other individuals in positions similar to the Grantee’s by the same percentage amount shall
not constitute such a salary reduction; or 
 (iii) requiring the Grantee to be based at any place outside a 50 mile radius from the

 (aa) “Grantee” means an
Employee, Director or Consultant who receives an Award under the Plan.

payout in accordance with the same (or, for the Grantee, a more favorable) vesting schedule applicable to such Award. The determination of Award comparability shall be made by the Administrator and its determination shall be final, binding and
conclusive.

to be issued pursuant to Awards may be authorized, but unissued, or reacquired Common Stock. 
 (b) Any Shares covered by an Award (or
portion of an Award) which is forfeited, canceled or expires (whether voluntarily or involuntarily) shall be deemed not to have been issued for purposes of determining the maximum aggregate number of Shares which may be issued under the Plan. Shares
that actually have been issued under the Plan pursuant to an Award shall not be returned to the Plan and shall not become available for future issuance under the Plan, except that if unvested Shares are forfeited, or repurchased by the Company at
their original purchase price, or at the lower of their original purchase price or their Fair Market Value at the time of repurchase, such Shares shall become available for future grant under the Plan. To the extent not prohibited by the listing
requirements of the NASDAQ Global Market (or other established stock exchange or national market system on which the Common Stock is traded) or Applicable Law, any Shares covered by an Award which are surrendered (i) in payment of the Award
exercise or purchase price (including pursuant to the “net exercise” of an option pursuant to Section 7(b)(v)) or (ii) in satisfaction of tax withholding obligations incident to the exercise, vesting or settlement of an Award

 4. Administration of the Plan. 

(a) Plan Administrator. 

(i) Administration with Respect to Directors and Officers. With respect to grants of Awards to Directors, or Employees who are also
Officers or Directors of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws and to permit such
grants and related transactions under the Plan to be exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. Once appointed, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board. In the case of Awards granted to Directors, or Employees who are also Officers or Directors of the Company, references to the “Administrator” or to a “Committee” shall be
deemed to be references to such Committee. 

  
 7 








 (ii) Administration With Respect to Consultants and Other Employees. With respect to
grants of Awards to Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a
manner as to satisfy the Applicable Laws. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. The Board or such Committee may authorize one or more Officers to grant such Awards
and may limit such authority as the Board or such Committee determines from time to time. 
 (iii) Administration With Respect to
Covered Employees. Notwithstanding the foregoing, it is intended that as of and after the date that the exemption for the Plan under Section 162(m) of the Code expires, as set forth in Section 18 below (or any exemption having similar
effect), grants of Awards to any Covered Employee intended to qualify as Performance-Based Compensation shall be made only by a Committee (or subcommittee of a Committee) which is comprised solely of two or more Directors eligible to serve on a
committee making Awards qualifying as Performance-Based Compensation. In the case of such Awards granted to Covered Employees, references to the “Administrator” or to a “Committee” shall be deemed to be references to such
Committee or subcommittee. 
 (iv) Administration Errors. In the event an Award is granted in a manner inconsistent with the
provisions of subsection (a)(iii), such Award shall be presumptively valid as of its grant date to the extent permitted by the Applicable Laws. 

(b) Powers of the Administrator. Subject to Applicable Laws and the provisions of the Plan (including any other powers given to the
Administrator hereunder), and except as otherwise provided by the Board, the Administrator shall have the authority, in its discretion: 

(i) to select the Employees, Directors and Consultants to whom Awards may be granted from time to time hereunder; 

(ii) to determine whether and to what extent Awards are granted hereunder; 

(iii) to determine the number of Shares or the amount of cash or other consideration to be covered by each Award granted hereunder; 

(iv) to approve forms of Award Agreements for use under the Plan; 

(v) to determine the terms and conditions of any Award granted hereunder; 

  
 8 








 (vi) to amend the terms of any outstanding Award granted under the Plan, provided that any
amendment that would adversely affect the Grantee’s rights under an outstanding Award shall not be made without the Grantee’s written consent; provided, however, that an amendment or modification that may cause an Incentive Stock Option to
become a Non-Qualified Stock Option shall not be treated as adversely affecting the rights of the Grantee; 

(vii) to prescribe, amend and rescind rules and regulations relating to the Plan and to define terms not otherwise defined herein; 

(viii) to construe and interpret the terms of the Plan and Awards, including without limitation, any notice of award or Award Agreement,
granted pursuant to the Plan; 
 (ix) to approve corrections in the documentation or administration of any Award; 

(x) to grant Awards to Employees, Directors and Consultants employed outside the United States or to otherwise adopt or administer such
procedures or subplans that the Administrator deems appropriate or necessary on such terms and conditions different from those specified in the Plan as may, in the judgment of the Administrator, be necessary or desirable to further the purpose of
the Plan; and 
 (xi) to take such other action, not inconsistent with the terms of the Plan, as the Administrator deems appropriate. 

The express grant in the Plan of any specific power to the Administrator shall not be construed as limiting any power or authority of the Administrator;
provided, however, that the Administrator may not exercise any right or power reserved to the Board. Any decision made, or action taken, by the Administrator in connection with the administration of this Plan in accordance with the terms hereof
shall be final, conclusive and binding on all persons having an interest in the Plan. 
 (c) Indemnification. In addition to such
other rights of indemnification as they may have as members of the Board or as Officers or Employees of the Company or a Related Entity, members of the Board and any Officers or Employees of the Company or a Related Entity to whom authority to act
for the Board, the Administrator or the Company is delegated shall be defended and indemnified by the Company to the extent permitted by law on an after-tax basis against all reasonable expenses, including
attorneys’ fees, actually and necessarily incurred in connection with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal related thereto, to which they or any of them may be a party by reason
of any action taken or failure to act under or in connection with the Plan, or any Award granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in
satisfaction of a judgment in any such claim, investigation, action, suit or proceeding, except in relation to matters as to which such member of the Board or Officer or Employee shall be adjudged in such claim, investigation, action, suit or
proceeding to be liable for gross negligence, bad faith or intentional misconduct; provided, however, that within thirty (30) days after the institution of such claim, investigation, action, suit or proceeding, such member of the Board or
Officer or Employee shall offer to the Company, in writing, the opportunity for the Company to defend such claim, investigation, action, suit or proceeding at the Company’s expense. 

  
 9 








 5. Eligibility. Awards other than Incentive Stock Options may be granted to Employees,
Directors and Consultants. Incentive Stock Options may be granted only to Employees of the Company or a Parent or a Subsidiary of the Company. An Employee, Director or Consultant who has been granted an Award may, if otherwise eligible, be granted
additional Awards. Awards may be granted to such Employees, Directors or Consultants who are residing in non-U.S. jurisdictions as the Administrator may determine from time to time. 

6. Terms and Conditions of Awards. 

(a) Types of Awards. The Administrator is authorized under the Plan to award any type of arrangement to an Employee, Director or
Consultant that is not inconsistent with the provisions of the Plan and that by its terms involves or might involve the issuance of (i) Shares, (ii) cash or (iii) an Option, SAR or similar right with a fixed or variable price related
to the Fair Market Value of the Shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions. Such awards may include,
without limitation, Options, SARs, sales or bonuses of Restricted Stock, Restricted Stock Units, Cash-Based Awards or Dividend Equivalent Rights, and an Award may consist of one such security or benefit, or two (2) or more of them in any
combination or alternative. 
 (b) Designation of Award. Each Award shall be designated in the Award Agreement. In the case of an
Option, the Option shall be designated as either an Incentive Stock Option or a Non-Qualified Stock Option. However, notwithstanding such designation, an Option will qualify as an Incentive Stock Option under
the Code only to the extent the $100,000 limitation of Section 422(d) of the Code is not exceeded. The $100,000 limitation of Section 422(d) of the Code is calculated based on the aggregate Fair Market Value of the Shares subject to
Options designated as Incentive Stock Options which become exercisable for the first time by a Grantee during any calendar year (under all plans of the Company or any Parent or Subsidiary of the Company). For purposes of this calculation, Incentive
Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the grant date of the relevant Option. In the event that the Code or the regulations promulgated
thereunder are amended after the date the Plan becomes effective to provide for a different limit on the Fair Market Value of Shares permitted to be subject to Incentive Stock Options, then such different limit will be automatically incorporated
herein and will apply to any Options granted after the effective date of such amendment. 

  
 10 








 (c) Conditions of Award. Subject to the terms of the Plan, the Administrator shall
determine the provisions, terms, and conditions of each Award including, but not limited to, the Award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash, Shares, or other consideration)
upon settlement of the Award, payment contingencies and satisfaction of any performance criteria. The performance criteria established by the Administrator for any Awards intended to be Performance-Based Compensation shall be one of, or a
combination of, the following: net earnings or net income (before or after taxes); earnings per share; revenues or sales (including net sales or revenue growth); net operating profit; return measures (including return on assets, net assets, capital,
invested capital, equity, sales, or revenue); cash flow (including operating cash flow, free cash flow, cash flow return on equity or cash flow return on investment); earnings before or after taxes, interest, depreciation and/or amortization; gross
or operating margins; productivity ratios; share price (including growth measures and total stockholder return); expense targets; margins; operating efficiency; market share; working capital targets and change in working capital; economic value
added or EVA® (net operating profit after tax minus the sum of capital multiplied by the cost of capital); or net operating income. The performance criteria established by the Administrator
for any Awards not intended to be Performance-Based Compensation may be based on any one of, or a combination of, the foregoing or any other performance criteria established by the Administrator. The performance criteria may be applicable to the
Company, Related Entities and/or any individual business units of the Company or any Related Entity and may be measured over any specified period, including but not limited to quarterly, semi-annually, annually or cumulatively over a period of
years, on an absolute basis or relative to a pre-established target, to previous years’ results or to a designated comparison group, in each case as specified by the Administrator. Partial achievement of
the specified criteria may result in a payment or vesting corresponding to the degree of achievement as specified in the Award Agreement. In addition, to the extent applicable to Awards intended to qualify as Performance-Based Compensation, the
performance criteria shall be calculated in accordance with generally accepted accounting principles, but excluding the effect (whether positive or negative) of any change in accounting standards and any extraordinary, unusual or nonrecurring item,
as determined by the Administrator, occurring after the establishment of the performance criteria applicable to the Award intended to be Performance-Based Compensation. Each such adjustment, if any, shall be made solely for the purpose of providing
a consistent basis from period to period for the calculation of performance criteria in order to prevent the dilution or enlargement of the Grantee’s rights with respect to an Award intended to be Performance-Based Compensation. 

(d) Acquisitions and Other Transactions. The Administrator may issue Awards under the Plan in settlement, assumption or substitution
for outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or an additional interest in a Related Entity whether by merger, stock purchase,
asset purchase or other form of transaction. 
 (e) Deferral of Award Payment. The Administrator may establish one or more programs
under the Plan to permit selected Grantees the opportunity to elect to defer receipt of consideration upon exercise of an Award, satisfaction of performance criteria, or other event that absent the election would entitle the Grantee to payment or
receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the timing of such elections, the mechanisms for payments of, and accrual of interest or other earnings, if any, on amounts, Shares or
other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program. 

(f) Separate Programs. The Administrator may establish one or more separate programs under the Plan for the purpose of issuing
particular forms of Awards to one or more classes of Grantees on such terms and conditions as determined by the Administrator from time to time. 

  
 11 








 (g) Individual Limitations on Awards. 

(i) Individual Limit for Options and SARs. Following the date that the exemption from application of Section 162(m) of the Code
described in Section 18 (or any exemption having similar effect) ceases to apply to Awards, the maximum number of Shares with respect to which Options and SARs may be granted to any Grantee in any calendar year shall be 500,000 Shares. In
connection with a Grantee’s commencement of Continuous Service, a Grantee may be granted Options and SARs for up to an additional 500,000 Shares which shall not count against the limit set forth in the previous sentence. The foregoing
limitations shall be adjusted proportionately in connection with any change in the Company’s capitalization pursuant to Section 10 below. To the extent required by Section 162(m) of the Code or the regulations thereunder, in applying
the foregoing limitations with respect to a Grantee, if any Option or SAR is canceled, the canceled Option or SAR shall continue to count against the maximum number of Shares with respect to which Options and SARs may be granted to the Grantee. For
this purpose, the repricing of an Option (or in the case of a SAR, reduction of the base amount on which the stock appreciation is calculated to reflect a reduction in the Fair Market Value of the Common Stock) shall be treated as the cancellation
of the existing Option or SAR and the grant of a new Option or SAR. 
 (ii) Individual Limit for Restricted Stock and Restricted Stock
Units. Following the date that the exemption from application of Section 162(m) of the Code described in Section 18 (or any exemption having similar effect) ceases to apply to Awards, for awards of Restricted Stock and Restricted Stock
Units that are intended to be Performance-Based Compensation, the maximum number of Shares with respect to which such Awards may be granted to any Grantee in any calendar year shall be 500,000 Shares. The foregoing limitation shall be adjusted
proportionately in connection with any change in the Company’s capitalization pursuant to Section 10 below. 
 (iii)
Individual Limit for Cash-Based Awards. Following the date that the exemption from application of Section 162(m) of the Code described in Section 18 (or any exemption having similar effect) ceases to apply to Awards, for Cash-Based
Awards that are intended to be Performance-Based Compensation, with respect to each twelve (12) month period that constitutes or is part of each Performance Period, the maximum amount that may be paid to a Grantee pursuant to such Awards shall
be $1,000,000. In addition, the foregoing limitation shall be prorated for any Performance Period consisting of fewer than twelve (12) months by multiplying such limitation by a fraction, the numerator of which is the number of months in the
Performance Period and the denominator of which is twelve (12). 
 (iv) Individual Limit for Awards to Members of the Board. The
maximum number of Shares with respect to which Awards may be granted to any member of the Board (in consideration for such member’s service as a member of the Board) in any calendar year shall be 200,000 Shares. 

(h) Deferral. If the vesting or receipt of Shares or cash under an Award is deferred to a later date, any amount (whether denominated
in Shares or cash) paid in addition to the original number of Shares or amount of cash subject to such Award will not be treated as an increase in the number of Shares or amount of cash subject to the Award if the additional amount is based either
on a reasonable rate of interest or on one or more predetermined actual investments such that the amount payable by the Company at the later date will be based on the actual rate of return of a specific investment (including any decrease as well as
any increase in the value of an investment). 

  
 12 








 (i) Early Exercise. The Award Agreement may, but need not, include a provision whereby the
Grantee may elect at any time while an Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award. Any unvested Shares received pursuant to such exercise may be subject to a repurchase right in favor
of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate. 
 (j) Term of Award.
The term of each Award shall be the term stated in the Award Agreement; provided, however, that the term of an Incentive Stock Option shall be no more than ten (10) years from the date of grant thereof. However, in the case of an Incentive
Stock Option granted to a Grantee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the term of the
Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Award Agreement. Notwithstanding the foregoing, the specified term of any Award shall not include any period for which
the Grantee has elected to defer the receipt of the Shares or cash issuable pursuant to the Award. 
 (k) Transferability of Awards.
Incentive Stock Options may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Grantee, only by the
Grantee. Other Awards shall be transferable (i) by will and by the laws of descent and distribution and (ii) during the lifetime of the Grantee, to the extent and in the manner authorized by the Administrator but only to the extent such
transfers are made to family members, to family trusts, to family controlled entities, to charitable organizations or pursuant to domestic relations orders or agreements, in all cases without payment for such transfers to the Grantee.
Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Award in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. 

(l) Time of Granting Awards. The date of grant of an Award shall for all purposes be the date on which the Administrator makes the
determination to grant such Award, or such other later date as is determined by the Administrator. 
 7. Award Exercise or Purchase
Price, Consideration and Taxes. 
 (a) Exercise or Purchase Price. The exercise or purchase price, if any, for an Award shall be
as follows: 
 (i) In the case of an Incentive Stock Option: 

(A) granted to an Employee who, at the time of the grant of such Incentive Stock Option owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the per Share exercise price shall be not less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant; or

 (B) granted to any Employee other than an Employee described in the preceding paragraph, the per Share exercise price shall be not less
than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

  
 13 








 (ii) In the case of a Non-Qualified Stock Option, the
per Share exercise price shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(iii) In the case of Awards intended to qualify as Performance-Based Compensation, the exercise or purchase price, if any, shall be not less
than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (iv) In the case of SARs, the base appreciation
amount shall not be less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (v) In the case of
other Awards, such price as is determined by the Administrator. 
 (vi) Notwithstanding the foregoing provisions of this
Section 7(a), in the case of an Award issued pursuant to Section 6(d), above, the exercise or purchase price for the Award shall be determined in accordance with the provisions of the relevant instrument evidencing the agreement to issue
such Award. 
 (b) Consideration. Subject to Applicable Laws, the consideration to be paid for the Shares to be issued upon exercise
or purchase of an Award, including the method of payment, shall be determined by the Administrator. In addition to any other types of consideration the Administrator may determine, the Administrator is authorized to accept as consideration for
Shares issued under the Plan the following, provided that the portion of the consideration equal to the par value of the Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: 

(i) cash; 
 (ii) check; 

(iii) surrender of Shares or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require
which have a Fair Market Value on the date of surrender or attestation equal to the aggregate exercise price of the Shares as to which said Award shall be exercised; 

(iv) with respect to Options, if the exercise occurs when the Common Stock is listed on one or more established stock exchanges or national
market systems, including without limitation the NASDAQ Stock Market, payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee (A) shall provide written instructions to a Company designated brokerage firm to
effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (B) shall provide written directives to the Company to deliver
the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction; 

  
 14 








 (v) with respect to Options, payment through a “net exercise” such that, without the
payment of any funds, the Grantee may exercise the Option and receive the net number of Shares equal to (i) the number of Shares as to which the Option is being exercised, multiplied by (ii) a fraction, the numerator of which is the Fair
Market Value per Share (on such date as is determined by the Administrator) less the exercise price per Share, and the denominator of which is such Fair Market Value per Share (the number of net Shares to be received shall be rounded down to
the nearest whole number of Shares); or 
 (vi) any combination of the foregoing methods of payment. 

The Administrator may at any time or from time to time, by adoption of or by amendment to the standard forms of Award Agreement described in
Section 4(b)(iv), or by other means, grant Awards which do not permit all of the foregoing forms of consideration to be used in payment for the Shares or which otherwise restrict one or more forms of consideration. 

(c) Taxes. No Shares or cash shall be delivered under the Plan to any Grantee or other person until such Grantee or other person has
made arrangements acceptable to the Administrator for the satisfaction of any non-U.S., federal, state, or local income and employment tax withholding obligations, including, without limitation, obligations
incident to the receipt of Shares or cash. The Administrator may provide in any Award Agreement that, upon exercise or vesting of an Award, the Company shall, at the election of the Grantee, withhold or collect from the Grantee an amount sufficient
to satisfy such tax obligations, including, but not limited to, by surrender of the whole number of Shares covered by the Award, if applicable, sufficient to satisfy the minimum applicable tax withholding obligations incident to the exercise or
vesting of an Award (reduced to the lowest whole number of Shares if such number of Shares withheld would result in withholding a fractional Share with any remaining tax withholding settled in cash). 

8. Exercise of Award. 

(a) Procedure for Exercise; Rights as a Stockholder. 

(i) Any Award granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator under the
terms of the Plan and specified in the Award Agreement. 
 (ii) An Award shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the Award by the person entitled to exercise the Award and full payment for the Shares with respect to which the Award is exercised has been made, including, to the extent
selected, use of the broker-dealer sale and remittance procedure to pay the purchase price as provided in Section 7(b)(iv). 

  
 15 








 (b) Exercise of Award Following Termination of Continuous Service. 

(i) An Award may not be exercised after the termination date of such Award set forth in the Award Agreement and may be exercised following
the termination of a Grantee’s Continuous Service only to the extent provided in the Award Agreement. 
 (ii) Where the Award
Agreement permits a Grantee to exercise an Award following the termination of the Grantee’s Continuous Service for a specified period, the Award shall terminate to the extent not exercised on the last day of the specified period or the last day
of the original term of the Award, whichever occurs first. 
 (iii) Any Award designated as an Incentive Stock Option to the extent not
exercised within the time permitted by law for the exercise of Incentive Stock Options following the termination of a Grantee’s Continuous Service shall convert automatically to a Non-Qualified Stock
Option and thereafter shall be exercisable as such to the extent exercisable by its terms for the period specified in the Award Agreement. 

9. Conditions Upon Issuance of Shares. 

(a) If at any time the Administrator determines that the delivery of Shares pursuant to the exercise, vesting or any other provision of an
Award is or may be unlawful under Applicable Laws, the vesting or right to exercise an Award or to otherwise receive Shares pursuant to the terms of an Award shall be suspended until the Administrator determines that such delivery is lawful and
shall be further subject to the approval of counsel for the Company with respect to such compliance. The Company shall have no obligation to effect any registration or qualification of the Shares under federal or state laws. 

(b) As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any Applicable Laws.

 10. Adjustments Upon Changes in Capitalization. Subject to any required action by the stockholders of the Company and
Section 11 hereof, the number of Shares covered by each outstanding Award, and the number of Shares which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan,
the exercise or purchase price of each such outstanding Award and the numerical limits set forth in Section 6(g), as well as any other terms that the Administrator determines require adjustment, shall be proportionately adjusted for
(i) any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, recapitalization, combination or reclassification of the Shares, or similar transaction affecting the Shares,
(ii) any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company, or (iii) any other transaction with respect to Common Stock including a corporate merger, consolidation,
acquisition of property or stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation (whether partial or complete) or any similar transaction; provided,
however that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” In the event of any distribution of cash or other assets to stockholders other than a normal
cash dividend, the Administrator shall also make such adjustments as provided in this Section 10 or substitute, exchange or grant Awards to effect such adjustments (collectively “adjustments”). Any such adjustments to outstanding
Awards will be effected in a manner that precludes the enlargement of rights and benefits under such Awards. In connection with the foregoing adjustments, the Administrator may, in its discretion, prohibit the exercise of Awards or other issuance of
Shares, cash or other consideration pursuant to Awards during certain periods of time. Except as the Administrator determines, no issuance by the Company of shares of any class, or securities convertible into shares of any class, shall affect, and
no adjustment by reason hereof shall be made with respect to, the number or price of Shares subject to an Award. 

  
 16 








 11. Corporate Transactions and Changes in Control. 

(a) Termination of Award to Extent Not Assumed in Corporate Transaction. Effective upon the consummation of a Corporate Transaction,
all outstanding Awards under the Plan shall terminate. However, all such Awards shall not terminate to the extent they are Assumed in connection with the Corporate Transaction.  

(b) Acceleration of Award Upon Corporate Transaction or Change in Control. The Administrator shall have the authority, exercisable
either in advance of any actual or anticipated Corporate Transaction or Change in Control or at the time of consummation of an actual Corporate Transaction or Change in Control (including at the time of the grant of an Award under the Plan or any
time while an Award remains outstanding), to provide for the full or partial automatic vesting and exercisability of one or more outstanding unvested Awards under the Plan and the release from restrictions on transfer or forfeiture rights of such
Awards in connection with a Corporate Transaction or Change in Control, on such terms and conditions as the Administrator may specify. The Administrator also shall have the authority to condition any such Award vesting and exercisability or release
from such limitations upon the subsequent termination of the Continuous Service of the Grantee within a specified period following the effective date of the Corporate Transaction or Change in Control. The Administrator may provide that any Awards so
vested or released from such limitations in connection with a Corporate Transaction or Change in Control shall remain fully exercisable until the expiration or sooner termination of the Award. 

(c) Effect of Acceleration on Incentive Stock Options. Any Incentive Stock Option accelerated under this Section 11 in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. 

12. Effective Date and Term of Plan. The Plan shall become effective on the IPO Date. It shall continue in effect for a term of ten
(10) years unless sooner terminated. Incentive Stock Options may only be granted for ten (10) years from the earlier to occur of the Plan’s adoption by the Board or its approval by the stockholders of the Company. Subject to
Section 17 below, and Applicable Laws, Awards may be granted under the Plan upon its becoming effective. 

  
 17 








 13. Amendment, Suspension or Termination of the Plan. 

(a) The Board may at any time amend, suspend or terminate the Plan; provided, however, that no such amendment shall be made without the
approval of the Company’s stockholders to the extent such approval is required by Applicable Laws. 
 (b) No Award may be granted
during any suspension of the Plan or after termination of the Plan. 
 (c) No suspension or termination of the Plan (including termination
of the Plan under Section 11 above) shall adversely affect any rights under Awards already granted to a Grantee. 
 14. Reservation
of Shares. 
 (a) The Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall
be sufficient to satisfy the requirements of the Plan. 
 (b) The inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares
as to which such requisite authority shall not have been obtained. 
 15. No Effect on Terms of Employment/Consulting Relationship.
The Plan shall not confer upon any Grantee any right with respect to the Grantee’s Continuous Service, nor shall it interfere in any way with his or her right or the right of the Company or any Related Entity to terminate the Grantee’s
Continuous Service at any time, with or without cause, including, but not limited to, Cause, and with or without notice. The ability of the Company or any Related Entity to terminate the employment of a Grantee who is employed at will is in no way
affected by its determination that the Grantee’s Continuous Service has been or has not been terminated for Cause for the purposes of this Plan. 

16. No Effect on Retirement and Other Benefit Plans. Except as specifically provided in a retirement or other benefit plan of the
Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the Company or a Related Entity, and shall not affect any benefits under any other benefit plan of
any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of compensation. The Plan is not a “Pension Plan” or “Welfare Plan” under the Employee Retirement Income
Security Act of 1974, as amended. 
 17. Stockholder Approval. The grant of Incentive Stock Options under the Plan shall be subject
to approval by the stockholders of the Company within twelve (12) months before or after the date the Plan is adopted excluding Incentive Stock Options issued in substitution for outstanding Incentive Stock Options pursuant to
Section 424(a) of the Code. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws. The Administrator may grant Incentive Stock Options under the Plan prior to approval by the stockholders, but until
such approval is obtained, no such Incentive Stock Option shall be exercisable. In the event that stockholder approval is not obtained within the twelve (12) month period provided above, all Incentive Stock Options previously granted under the
Plan shall be exercisable as Non-Qualified Stock Options. 

  
 18 








 18. Effect of Section 162(m) of the Code. The numerical limits set
forth in Section 6(g)(i)-(iii) of the Plan shall not be applicable until the expiration of the transition period set forth in Treasury Regulation Section 1.162-27(f). Under such Treasury Regulation,
this exemption is available to the Plan for the duration of the period that lasts until the earliest of: (i) the expiration of the Plan; (ii) the material modification of the Plan; (iii) the exhaustion of the maximum number of shares
of Common Stock and other compensation available for Awards under the Plan, as set forth in Section 3; (iv) the first meeting of stockholders at which directors are to be elected that occurs after the close of the third calendar year
following the calendar year in which the Company first becomes subject to the reporting obligations of Section 12 of the Exchange Act; or (v) such other date required by Section 162(m) of the Code and the rules and regulations
promulgated thereunder. Notwithstanding anything herein to the contrary, the Administrator may, in its sole discretion, grant Awards at any time, including after the expiration of the transition period set forth in Treasury Regulation Section 1.162-27(f), that are not intended to (or otherwise do not) qualify as Performance-Based Compensation. 

19. Unfunded Obligation. Grantees shall have the status of general unsecured creditors of the Company. Any amounts payable to Grantees
pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended. Neither the Company nor any Related Entity shall be
required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust
investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Grantee account shall not create or constitute a trust or fiduciary relationship between the
Administrator, the Company or any Related Entity and a Grantee, or otherwise create any vested or beneficial interest of any Grantee or the Grantee’s creditors in any assets of the Company or a Related Entity. The Grantees shall have no claim
against the Company or any Related Entity for any changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan. 

20. Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of
any provision of the Plan. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly
requires otherwise. 
 21. Clawback/Recoupment. Each Award shall be subject to reduction, cancellation, forfeiture or recoupment to
the extent necessary to comply with (i) any clawback, forfeiture or other similar policy adopted by the Board or the Administrator and as in effect from time to time, or (ii) Applicable Laws (including without limitation Section 304
of the Sarbanes Oxley Act and Section 954 of the Dodd Frank Act), whether such policy or Applicable Law becomes effective prior to or following the grant of such Award, and the Company may take such actions as may, in its discretion, be
necessary to effectuate any such policy or comply with Applicable Law. 

  
 19 








 22. Compliance With Section 409A of the Code. To the extent applicable,
Awards will be designed and operated in such a manner that they are either exempt from the application of, or comply with, the requirements of Section 409A of the Code. The Plan and each Award Agreement are intended to meet the requirements of
Section 409A of the Code and will be construed and interpreted in accordance with such intent, except as otherwise determined in the Administrator’s sole discretion. Notwithstanding the foregoing, the Company makes no representation with
respect to the tax compliance of the Plan or any Award Agreement, including compliance with Section 409A of the Code. 
 23.
Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board, the submission of the Plan to the stockholders of the Company for approval, nor any provision of the Plan will be construed as creating any limitations on the power of
the Board to adopt such additional compensation arrangements as it may deem desirable, including, without limitation, the granting of Awards otherwise than under the Plan, and such arrangements may be either generally applicable or applicable only
in specific cases.

 THE GRANTEE ACKNOWLEDGES AND AGREES THAT THE SHARES SUBJECT TO THE OPTION SHALL VEST, IF AT ALL, ONLY DURING THE PERIOD
OF THE GRANTEE’S CONTINUOUS SERVICE OR AS OTHERWISE SPECIFICALLY PROVIDED HEREIN (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER). THE GRANTEE FURTHER ACKNOWLEDGES AND AGREES THAT NOTHING IN THIS
NOTICE, THE OPTION AGREEMENT, OR THE PLAN SHALL CONFER UPON THE GRANTEE ANY RIGHT WITH RESPECT TO FUTURE AWARDS OR CONTINUATION OF THE GRANTEE’S CONTINUOUS SERVICE, NOR SHALL IT INTERFERE IN ANY WAY WITH THE GRANTEE’S RIGHT OR THE RIGHT OF
THE COMPANY OR RELATED ENTITY TO WHICH THE GRANTEE PROVIDES SERVICES TO TERMINATE THE GRANTEE’S CONTINUOUS SERVICE AT ANY TIME, WITH OR WITHOUT CAUSE, AND WITH OR WITHOUT NOTICE. THE GRANTEE ACKNOWLEDGES THAT UNLESS THE GRANTEE HAS A WRITTEN

“Plan Documents”) to the Grantee by electronic means or request the Grantee’s consent to participate in the Plan by electronic means. The Grantee hereby agrees to Company’s provision to the Grantee of these documents by

 Award Number:             

ATHENEX, INC. 2017 OMNIBUS INCENTIVE PLAN 

STOCK OPTION AWARD AGREEMENT 

1. Grant of Option. Athenex, Inc., a Delaware corporation (the “Company”), hereby grants to the Grantee (the
“Grantee”) named in the Notice of Stock Option Award (the “Notice”), an option (the “Option”) to purchase the Total Number of Shares of Common Stock subject to the Option (the “Shares”) set forth in the
Notice, at the Exercise Price per Share set forth in the Notice (the “Exercise Price”) subject to the terms and provisions of the Notice, this Stock Option Award Agreement (the “Option Agreement”) and the Company’s 2017
Omnibus Incentive Plan, as amended from time to time (the “Plan”), which are incorporated herein by reference. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option Agreement.

 If designated in the Notice as an Incentive Stock Option, the Option is intended to qualify as an Incentive Stock Option as defined in
Section 422 of the Code. However, notwithstanding such designation, the Option will qualify as an Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. The
$100,000 limitation of Section 422(d) of the Code is calculated based on the aggregate Fair Market Value of the Shares subject to options designated as Incentive Stock Options which become exercisable for the first time by the Grantee during
any calendar year (under all plans of the Company or any Parent or Subsidiary of the Company). For purposes of this calculation, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value
of the shares subject to such options shall be determined as of the grant date of the relevant option. 
 2. Exercise of Option.

 (a) Right to Exercise. The Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the
Notice and with the applicable provisions of the Plan and this Option Agreement. The Grantee shall be subject to reasonable limitations on the number of requested exercises during any monthly or weekly period as determined by the Administrator. In
no event shall the Company issue fractional Shares. 
 (b) Method of Exercise. The Option shall be exercisable by delivery of an
exercise notice (a form of which is attached as Exhibit A) or by such other procedure as specified from time to time by the Administrator which shall state the election to exercise the Option, the whole number of Shares in respect of which the
Option is being exercised, and such other provisions as may be required by the Administrator. The exercise notice shall be delivered in person, by certified mail, or by such other method (including electronic transmission) as determined from time to
time by the Administrator to the Company accompanied by payment of the Exercise Price and all applicable income and employment taxes required to be withheld. The Option shall be deemed to be exercised upon receipt by the Company of such notice
accompanied by the Exercise Price and all applicable withholding taxes, which, to the extent selected, shall be deemed to be satisfied by use of the broker-dealer sale and remittance procedure to pay the Exercise Price provided in Section 3(d)
below to the extent such procedure is available to the Grantee at the time of exercise and such an exercise would not violate any Applicable Law. 

(c) Taxes. No Shares will be delivered to the Grantee or other person pursuant to the exercise of the Option until the Grantee or
other person has made arrangements acceptable to the Administrator for the satisfaction of applicable income tax and employment tax withholding obligations, including, without limitation, such other tax obligations of the Grantee incident to the
receipt of Shares. Upon exercise of the Option, the Company or the Grantee’s employer may offset or withhold (from any amount owed by the Company or the Grantee’s employer to the Grantee) or collect from the Grantee or other person an
amount sufficient to satisfy such tax withholding obligations. Furthermore, in the event of any determination that the Company and/or a Related Entity has failed to withhold a sum sufficient to pay all withholding taxes due in connection with the
Option, the Grantee agrees to pay the Company and/or the Related Entity the amount of such deficiency in cash within five (5) days after receiving a written demand from the Company and/or the Related Entity to do so, whether or not the Grantee
is an employee of the Company and/or the Related Entity at that time. 
 (d) Section 16(b). Notwithstanding any provision
of this Option Agreement to the contrary, other than termination of the Grantee’s Continuous Service for Cause, if a sale within the applicable time periods set forth in Sections 5, 6 or 7 herein of Shares acquired upon the exercise of the
Option would subject the Grantee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such Shares by the
Grantee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Grantee’s termination of Continuous Service, or (iii) the date on which the Option expires. 

  








 3. Method of Payment. [Payment of the Exercise Price shall be made by any of the
following, or a combination thereof, at the election of the Grantee; provided, however, that such exercise method does not then violate any Applicable Law and, provided further, that the portion of the Exercise Price equal to the par value of the
Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: 
 (a) cash; 

(b) check; 
 (c) surrender of
Shares held for the requisite period, if any, necessary to avoid a charge to the Company’s earnings for financial reporting purposes, or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require
which have a Fair Market Value on the date of surrender or attestation equal to the aggregate Exercise Price of the Shares as to which the Option is being exercised; 

(d) payment through a “net exercise” such that, without the payment of any funds, the Grantee may exercise the Option and receive
the net number of Shares equal to (i) the number of Shares as to which the Option is being exercised, multiplied by (ii) a fraction, the numerator of which is the Fair Market Value per Share (on such date as is determined by the
Administrator) less the Exercise Price per Share, and the denominator of which is such Fair Market Value per Share (the number of net Shares to be received shall be rounded down to the nearest whole number of Shares); or 

(e) payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee (i) shall provide written instructions to
a Company-designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (ii) shall provide
written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction]. 

4. Restrictions on Exercise. The Option may not be exercised if the issuance of the Shares subject to the Option upon such exercise
would constitute a violation of any Applicable Laws. In addition, the Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company. If the exercise of the Option within the applicable time periods set
forth in Section 5, 6 and 7 of this Option Agreement is prevented by the provisions of this Section 4, the Option shall remain exercisable until one (1) month after the date the Grantee is notified by the Company that the Option is
exercisable, but in any event no later than the Expiration Date set forth in the Notice. 
 5. Termination or Change of Continuous
Service. In the event the Grantee’s Continuous Service terminates, other than for Cause, the Grantee may, but only during the Post-Termination Exercise Period, exercise the portion of the Option that was vested at the date of such
termination (the “Termination Date”). The Post-Termination Exercise Period shall commence on the Termination Date. In the event of termination of the Grantee’s Continuous Service for Cause, the Grantee’s right to exercise the
Option shall, except as otherwise determined by the Administrator, terminate concurrently with the termination of the Grantee’s Continuous Service (also the “Termination Date”). In no event, however, shall the Option be exercised
later than the Expiration Date set forth in the Notice. With respect to any Incentive Stock Option that shall remain in effect after a change in status from Employee to Director or Consultant, such Incentive Stock Option shall cease to be treated as
an Incentive Stock Option and shall be treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day following such change in status. Except as provided in Sections 6 and 7
below, to the extent that the Option was unvested on the Termination Date, or if the Grantee does not exercise the vested portion of the Option within the Post-Termination Exercise Period, the Option shall terminate. 

  








 6. Disability of Grantee. In the event the Grantee’s Continuous Service terminates as
a result of his or her Disability, the Grantee may, but only within [twelve (12) months] commencing on the Termination Date (but in no event later than the Expiration Date), exercise the portion of the Option that was vested on the Termination
Date; provided, however, that if such Disability is not a “disability” as such term is defined in Section 22(e)(3) of the Code and the Option is an Incentive Stock Option, such Incentive Stock Option shall cease to be treated as an
Incentive Stock Option and shall be treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day following the Termination Date. To the extent that the Option was unvested on
the Termination Date, or if the Grantee does not exercise the vested portion of the Option within the time specified herein, the Option shall terminate. Section 22(e)(3) of the Code provides that an individual is permanently and totally
disabled if he or she is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a
continuous period of not less than twelve (12) months. 
 7. Death of Grantee. In the event of the termination of the
Grantee’s Continuous Service as a result of his or her death, or in the event of the Grantee’s death during the Post-Termination Exercise Period or during the [twelve (12) month] period following the Grantee’s termination of
Continuous Service as a result of his or her Disability, the person who acquired the right to exercise the Option pursuant to Section 8 may exercise the portion of the Option that was vested at the date of termination within [twelve (12)
months] commencing on the date of death (but in no event later than the Expiration Date). To the extent that the Option was unvested on the date of death, or if the vested portion of the Option is not exercised within the time specified herein, the
Option shall terminate. 
 8. Transferability of Option. The Option, if an Incentive Stock Option, may not be transferred in any
manner other than by will or by the laws of descent and distribution and may be exercised during the lifetime of the Grantee only by the Grantee. The Option, if a Non-Qualified Stock Option, may not be
transferred in any manner other than by will or by the laws of descent and distribution, provided, however, that a Non-Qualified Stock Option may be transferred during the lifetime of the Grantee to the extent
and in the manner authorized by the Administrator. Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Incentive Stock Option or Non-Qualified Stock Option
in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. Following the death of the Grantee, the Option, to the extent provided in Section 7, may be exercised (a) by the person or persons
designated under the deceased Grantee’s beneficiary designation or (b) in the absence of an effectively designated beneficiary, by the Grantee’s legal representative or by any person empowered to do so under the deceased
Grantee’s will or under the then applicable laws of descent and distribution. The terms of the Option shall be binding upon the executors, administrators, heirs, successors and transferees of the Grantee. 

9. Term of Option. The Option must be exercised no later than the Expiration Date set forth in the Notice or such earlier date as
otherwise provided herein. After the Expiration Date or such earlier date, the Option shall be of no further force or effect and may not be exercised. 

10. Tax Consequences. The Grantee may incur tax liability as a result of the Grantee’s purchase or disposition of the Shares. THE
GRANTEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES. 
 11. Entire Agreement: Governing Law.
The Notice, the Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Grantee with respect
to the subject matter hereof, and may not be modified adversely to the Grantee’s interest except by means of a writing signed by the Company and the Grantee. Nothing in the Notice, the Plan and this Option Agreement (except as expressly
provided therein) is intended to confer any rights or remedies on any persons other than the parties. The Notice, the Plan and this Option Agreement are to be construed in accordance with and governed by the internal laws of the State of [●]
without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the internal laws of the State of [●] to the rights and duties of the parties. Should any provision of the Notice, the
Plan or this Option Agreement be determined to be illegal or unenforceable, such provision shall be enforced to the fullest extent allowed by law and the other provisions shall nevertheless remain effective and shall remain enforceable. 

  








 12. Lock-Up Agreement. 

(a) Agreement. The Grantee, if requested by the Company and the lead underwriter of any public offering of the Common Stock (the
“Lead Underwriter”), hereby irrevocably agrees not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of any interest in any
Common Stock or any securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Common Stock (except Common Stock included in the public offering or acquired on the public market after the offering)
during the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act of 1933, as amended, or any shorter or longer period of time as the Lead
Underwriter will specify. The Grantee further agrees to sign all documents as may be requested by the Lead Underwriter to effect the foregoing and agrees that the Company may impose stop-transfer instructions with respect to the Common Stock subject
to the lock-up period until the end of the applicable period. The Company and the Grantee acknowledge that each Lead Underwriter of a public offering of the Company’s stock, during the period of the
offering and for the lock-up period thereafter, is an intended beneficiary of this Section 12. 

(b) No Amendment Without Consent of Underwriter. During the period from identification of a Lead Underwriter in connection with any
public offering of the Company’s Common Stock until the earlier of (i) the expiration of the lock-up period specified in Section 12(a) in connection with the offering or (ii) the
abandonment of the offering by the Company and the Lead Underwriter, the provisions of this Section 12 may not be amended or waived except with the consent of the Lead Underwriter. 

13. Construction. The captions used in the Notice and this Option Agreement are inserted for convenience and shall not be deemed a part
of the Option for construction or interpretation. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless
the context clearly requires otherwise. 
 14. Administration and Interpretation. Any question or dispute regarding the
administration or interpretation of the Notice, the Plan or this Option Agreement shall be submitted by the Grantee or by the Company to the Administrator. The resolution of such question or dispute by the Administrator shall be final and binding on
all persons. 
 15. Venue [and Waiver of Jury Trial]. The Company, the Grantee, and the Grantee’s assignees pursuant to
Section 8 (the “parties”) agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this Option Agreement shall be brought in the United States District Court for [●] (or should such court
lack jurisdiction to hear such action, suit or proceeding, in a [●] state court in [●]) and that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any
objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. [THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR
PROCEEDING.] If any one or more provisions of this Section 15 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to
make it or its application valid and enforceable. 
 16. Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery, upon deposit for delivery by an internationally recognized express mail courier service or upon deposit in the United States mail by certified mail (if the parties are within the
United States), with postage and fees prepaid, addressed to the other party at its address as shown in these instruments, or to such other address as such party may designate in writing from time to time to the other party. 

17. Language. If the Grantee has received this Option Agreement or any other document related to the Plan translated into a language
other than English and if the translated version is different than the English version, the English version will control, unless otherwise prescribed by Applicable Law. 

18. Nature of Award. In accepting the Award, the Grantee acknowledges and agrees that: 

(a) the Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended or
terminated by the Company at any time, unless otherwise provided in the Plan and this Option Agreement; 

  








 (b) the Award is voluntary and occasional and does not create any contractual or other right to
receive future awards, or benefits in lieu of awards, even if awards have been awarded repeatedly in the past; 
 (c) all decisions with
respect to future awards, if any, will be at the sole discretion of the Company; 
 (d) the Grantee’s participation in the Plan is
voluntary; 
 (e) the Grantee’s participation in the Plan shall not create a right to any employment with the Grantee’s employer
and shall not interfere with the ability of the Company or the employer to terminate the Grantee’s employment relationship, if any, at any time; 

(f) the Award is not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any
severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments and in no event should be considered as compensation for, or relating in any way
to, past services for the Company or any Related Entity; 
 (g) in the event that the Grantee is not an Employee of the Company or any
Related Entity, the Award and the Grantee’s participation in the Plan will not be interpreted to form an employment or service contract or relationship with the Company or any Related Entity; 

(h) the future value of the underlying Shares is unknown and cannot be predicted with certainty; 

(i) in consideration of the Award, no claim or entitlement to compensation or damages shall arise from termination of the Award or diminution
in value of the Award or Shares acquired upon vesting of the Award, resulting from termination of the Grantee’s Continuous Service by the Company or any Related Entity (for any reason whatsoever and whether or not in breach of local labor laws)
and in consideration of the grant of the Award, the Grantee irrevocably releases the Company and any Related Entity from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction
to have arisen, then, by signing the Notice, the Grantee shall be deemed irrevocably to have waived his or her right to pursue or seek remedy for any such claim or entitlement; 

(j) in the event of termination of the Grantee’s Continuous Service (whether or not in breach of local labor laws), the Grantee’s
right to receive Awards under the Plan and to vest in such Awards, if any, will (except as otherwise provided in the Notice or herein) terminate effective as of the date that the Grantee is no longer providing services and will not be extended by
any notice period mandated under local law (e.g., providing services would not include a period of “garden leave” or similar period pursuant to local law); furthermore, in the event of termination of the Grantee’s Continuous
Service (whether or not in breach of local labor laws), the Administrator shall have the exclusive discretion to determine when the Grantee is no longer providing services for purposes of this Award; 

(k) the Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the
Grantee’s participation in the Plan or the Grantee’s acquisition or sale of the underlying Shares; and 
 (l) the Grantee is
hereby advised to consult with the Grantee’s own personal tax, legal and financial advisers regarding the Grantee’s participation in the Plan before taking any action related to the Plan. 

19. Data Privacy. 
 (a)
The Grantee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of the Grantee’s personal data as described in the Notice and this Option Agreement by and among, as applicable, the
Grantee’s employer, the Company and any Related Entity for the exclusive purpose of implementing, administering and managing the Grantee’s participation in the Plan. 

  








 (b) The Grantee understands that the Company and the Grantee’s employer may hold certain
personal information about the Grantee, including, but not limited to, the Grantee’s name, home address and telephone number, date of birth, social insurance or other identification number, salary, nationality, job title, any Shares or
directorships held in the Company, details of all Awards or any other entitlement to Shares awarded, canceled, vested, unvested or outstanding in the Grantee’s favor, for the exclusive purpose of implementing, administering and managing the
Plan (“Data”). 
 (c) The Grantee understands that Data will be transferred to any third party assisting the Company with the
implementation, administration and management of the Plan. The Grantee understands that the recipients of the Data may be located in the Grantee’s country, or elsewhere, and that the recipients’ country may have different data privacy laws
and protections than the Grantee’s country. The Grantee understands that the Grantee may request a list with the names and addresses of any potential recipients of the Data by contacting the Grantee’s local human resources representative.
The Grantee authorizes the Company and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in
electronic or other form, for the sole purpose of implementing, administering and managing the Grantee’s participation in the Plan. The Grantee understands that Data will be held only as long as is necessary to implement, administer and manage
the Grantee’s participation in the Plan. The Grantee understands that the Grantee may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or
withdraw the consents herein, in any case without cost, by contacting in writing the Grantee’s local human resources representative. The Grantee understands, however, that refusal or withdrawal of consent may affect the Grantee’s ability
to participate in the Plan. For more information on the consequences of the Grantee’s refusal to consent or withdrawal of consent, the Grantee understands that the Grantee may contact the Grantee’s local human resources representative.
