Journal or such other source as the Administrator deems reliable; or

 4. Administration of the Plan. 

(a) Plan Administrator. 

(i) Administration with Respect to Directors and Officers. Prior to the Registration Date, 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. On or after the Registration Date, 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. 
 (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. 
 (iii) Administration With Respect to Covered Employees. Notwithstanding the foregoing, 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 19 below, 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. 
 (b)
Multiple Administrative Bodies. The Plan may be administered by different bodies with respect to Directors, Officers, Consultants, and Employees who are neither Directors nor Officers. 

(c) 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; 

  
 7 







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

(iii) to determine the number of Shares or the amount of 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; 

(vi) to establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable non-U.S. jurisdictions and
to afford Grantees favorable treatment under such rules or laws; provided, however, that no Award shall be granted under any such additional terms, conditions, rules or procedures with terms or conditions which are inconsistent with the provisions
of the Global Stock Option Plan and this Plan; 
 (vii) 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. Notwithstanding the foregoing, (A) the reduction or increase of the exercise price of
any Option awarded under the Plan and the base appreciation amount of any SAR awarded under the Plan and (B) canceling an Option or SAR at a time when its exercise price or base appreciation amount (as applicable) exceeds the Fair Market Value
of the underlying Shares, in exchange for another Option, SAR, Restricted Stock, or other Award, in each case, shall not be subject to stockholder approval; 

(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; and 
 (ix) 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 that the Administrator may not exercise any right or power reserved to the Board. Any decision made or action taken by the Administrator or in connection with the administration of this Plan shall be final, conclusive and
binding on all persons having an interest in the Plan. 
 (d) 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


  
 8 







 
in connection with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, 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 it shall be adjudged in such claim, investigation, action, suit or proceeding that such person is 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 person shall offer to the Company, in writing, the opportunity at the
Company’s expense to defend the same. 
 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 Global Stock Option Plan and this 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 include, without limitation, Options, SARs, sales or bonuses of Restricted Stock, Restricted Stock Units or Dividend Equivalent Rights, and an Award may consist of one such security or benefit, or two 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. 

  
 9 







 (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 may be based on any one of, or combination of, increase in share price, earnings per share,
total stockholder return, return on equity, return on assets, return on investment, net operating income, cash flow, revenue, economic value added, personal management objectives, or other measure of performance selected 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, 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. 

(g) Individual Limitations on Awards. 

(i) Individual Option and SAR Limit. Following the date that the exemption from application of Section 162(m) of the Code
described in Section 19 (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


  
 10 







 
shall be thirty five thousand (35,000) Shares. 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 limitation 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, the base amount on which the stock appreciation is
calculated is reduced 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 19 (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 thirty five thousand (35,000) Shares. The foregoing limitation shall be adjusted proportionately in connection with any
change in the Company’s capitalization pursuant to Section 10 below. 
 (h) 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. 

(i) Term of Award. The term of each Award shall be the term stated in the Award Agreement, provided, however, that the term shall be no
more than ten (10) years from the date of issuance of the Options by the Company. 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. 

(j) 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 by gift or pursuant to a domestic relations order to members of the Grantee’s Immediate Family. 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. 

(k) 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. 

  
 11 







 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. 
 (ii) In the case of a
Non-Qualified Stock Option, the per Share exercise price shall be such price as is determined by the Administrator. 
 (iii) In the case of
SARs, the base appreciation amount shall be such amount as is determined by the Administrator. 
 (iv) 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. 

(v) In the case of the sale of Shares, the per Share purchase price, if any, shall be such price as is determined by the Administrator. 

(vi) In the case of other Awards, such price as is determined by the Administrator. 

(vii) 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; or 

  
 12 







 (ii) check. 

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(c)(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 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. Upon
exercise or vesting of an Award the Company shall 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 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. 

(b) Exercise of Award Following Termination of Continuous Service. In the event of termination of a Grantee’s Continuous Service
for any reason other than Disability or death (but not in the event of a Grantee’s change of status from Employee to Consultant or from Consultant to Employee), such Grantee may, but only during the Post-Termination Exercise Period (but in no
event later than the expiration date of the term of such Award as set forth in the Award Agreement), exercise the portion of the Grantee’s Award that was vested at the date of such termination or such other portion of the Grantee’s Award
as may be determined by the Administrator. The Grantee’s Award Agreement may provide that upon the termination of the Grantee’s Continuous Service for Cause, the Grantee’s right to exercise the Award shall terminate concurrently with
the termination of Grantee’s Continuous Service. 

  
 13 







 In the event of a Grantee’s change of status from Employee to Consultant, an Employee’s Incentive Stock
Option shall convert automatically to a Non-Qualified Stock Option on the day three (3) months and one day following such change of status. To the extent that the Grantee’s Award was unvested at the date of termination, or if the Grantee
does not exercise the vested portion of the Grantee’s Award within the Post-Termination Exercise Period, the Award shall terminate. 

(c) Disability of Grantee. In the event of termination of a Grantee’s Continuous Service as a result of his or her Disability,
such Grantee may, but only within twelve (12) months from the date of such termination (or such longer period as specified in the Award Agreement but in no event later than the expiration date of the term of such Award as set forth in the Award
Agreement), exercise the portion of the Grantee’s Award that was vested at the date of such termination; provided, however, that if such Disability is not a “disability” as such term is defined in Section 22(e)(3) of the Code, in
the case of an Incentive Stock Option such Incentive Stock Option shall automatically convert to a Non-Qualified Stock Option on the day three (3) months and one day following such termination. To the extent that the Grantee’s Award was
unvested at the date of termination, or if Grantee does not exercise the vested portion of the Grantee’s Award within the time specified herein, the Award shall terminate. 

(d) Death of Grantee. In the event of a termination of the Grantee’s Continuous Service as a result of his or her death, or in the
event of the death of the Grantee 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 Grantee’s estate
or a person who acquired the right to exercise the Award by bequest or inheritance may exercise the portion of the Grantee’s Award that was vested as of the date of termination, within twelve (12) months from the date of death (or such
longer period as specified in the Award Agreement but in no event later than the expiration of the term of such Award as set forth in the Award Agreement). To the extent that, at the time of death, the Grantee’s Award was unvested, or if the
Grantee’s estate or a person who acquired the right to exercise the Award by bequest or inheritance does not exercise the vested portion of the Grantee’s Award within the time specified herein, the Award shall terminate. 

(e) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of an Award within the applicable time
periods set forth in this Section 8 is prevented by the provisions of Section 9 below, the Award shall remain exercisable until one (1) month after the date the Grantee is notified by the Company that the Award is exercisable, but in
any event no later than the expiration of the term of such Award as set forth 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. 

  
 14 







 (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, the maximum number of Shares with respect to which Awards may be granted to any Grantee in any calendar year, 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, 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. 
 11.
Corporate Transactions. 
 (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) The Administrator shall have the authority, exercisable either in advance of any actual or anticipated Corporate Transaction or at the
time of an actual Corporate Transaction and exercisable 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 and repurchase or forfeiture rights of such Awards in connection with a Corporate Transaction, on such terms and conditions as the Administrator may specify.
The 

  
 15 







 
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. The Administrator may provide that any Awards so vested or released from such limitations in connection with, 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 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. To the extent such dollar limitation is exceeded, the excess Options shall be treated as Non-Qualified Stock Options. 
 12.
Effective Date and Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It shall continue in effect for a term of ten (10) years unless
sooner terminated. Subject to Section 17 below, and Applicable Laws, Awards may be granted under the Plan upon its becoming effective. 

13. Amendment, Suspension or Termination of the Plan. 

(a) The Board may at any time amend, suspend or terminate the Plan. To the extent necessary to comply with Applicable Laws, the Company shall
obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required. 
 (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 12, 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 a Related Entity to terminate the Grantee’s
Continuous Service at any time, with or without Cause, and with or 

  
 16 







 
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 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 “Retirement Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended. 
 17.
Stockholder Approval. Continuance of 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. Such stockholder approval shall be obtained in the
degree and manner required under Applicable Laws. Any Award exercised before stockholder approval is obtained shall be rescinded if stockholder approval is not obtained within the time prescribed, and Shares issued on the exercise of any such Award
shall not be counted in determining whether stockholder approval is obtained. 
 18. Information to Grantees. To the extent required
by Applicable Law, the Company shall provide to each Grantee, during the period for which such Grantee has one or more Awards outstanding, copies of financial statements at least annually. The Company shall not be required to provide such
information to persons whose duties in connection with the Company assure them access to equivalent information. 
 19. Effect of
Section 162(m) of the Code. Section 162(m) of the Code does not apply to the Plan prior to the Registration Date or such earlier time that the Company first becomes subject to the reporting obligations of Section 12 of the
Exchange Act. Following the Registration Date or such earlier time that the Company first becomes subject to the reporting obligations of Section 12 of the Exchange Act, the Plan, and all Awards (except Awards of Restricted Stock that vest over
time) issued thereunder, are intended to be exempt from the application of Section 162(m) of the Code, which restricts under certain circumstances the Federal income tax deduction for compensation paid by a public company to named executives in
excess of $1 million per year. The exemption is based on Treasury Regulation Section 1.162- 27(f), in the form existing on the effective date of the Plan, with the understanding that such regulation generally exempts from the application of
Section 162(m) of the Code compensation paid pursuant to a plan that existed before a company becomes publicly held. 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 available for Awards under the Plan, as set forth in Section 3(a),
(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. To the extent that the Administrator determines as of the date of grant of an Award
that (A) the Award is intended to qualify as 

  
 17 







 
Performance-Based Compensation and (B) the exemption described above is no longer available with respect to such Award, such Award shall not be effective until any stockholder approval
required under Section 162(m) of the Code has been obtained. 
 20. 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 in 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. 

21. 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. 
 22. No exclusivity 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.
