 3. Administration. 

3.1 Committee Members. The Plan shall be administered by the Committee. To the extent deemed necessary by the Board, each Committee
member shall satisfy the requirements for (i) an “independent director” under rules adopted by the NASDAQ or other principal exchange on which the Common Stock is then listed and (ii) a “nonemployee director” within the
meaning of Rule 16b-3 under the Exchange Act. Notwithstanding the foregoing, the mere fact that a Committee member shall fail to qualify under any of the foregoing requirements shall not invalidate any Award
made by the Committee which Award is otherwise validly made under the Plan. The Board may exercise all powers of the Committee hereunder and may directly administer the Plan. Neither the Company nor any member of the Board or Committee shall be
liable for any action or determination made in good faith by the Board or Committee with respect to the Plan or any Award thereunder. 
 3.2
Committee Authority. The Committee shall have all powers and discretion necessary or appropriate to administer the Plan and to control its operation, including, but not limited to, the power to (i) determine the Eligible Persons to whom
Awards shall be granted under the Plan, (ii) prescribe the restrictions, terms and conditions of all Awards, (iii) interpret the Plan and terms of the Awards, (iv) adopt rules for the administration, interpretation and application of
the Plan as are consistent therewith, and interpret, amend or revoke any such rules, (v) make all determinations with respect to a Participant’s Service and the termination of such Service for purposes of any Award, (vi) correct any
defect(s) or omission(s) or reconcile any ambiguity(ies) or inconsistency(ies) in the Plan or any Award thereunder, (vii) make all determinations it deems advisable for the administration of the Plan, (viii) decide all disputes arising in
connection with the Plan and to otherwise supervise the administration of the Plan, (ix) subject to the terms of the Plan, amend the terms of an Award in any manner that is not inconsistent with the Plan, (x) accelerate the vesting or, to
the extent applicable, exercisability of any Award at any time (including, but not limited to, upon a Change in Control or upon termination of Service of a Participant under certain circumstances (including, without limitation, upon retirement)) and
(xi) adopt such procedures, modifications or subplans as are necessary or appropriate to permit participation in the Plan by Eligible Persons who are foreign nationals or provide services outside of the United States. The Committee’s
determinations under the Plan need not be uniform and may be made by the Committee selectively among Participants and Eligible Persons, whether or not such Persons are similarly situated. The Committee shall, in its discretion, consider such factors
as it deems relevant in making its interpretations, determinations and actions under the Plan including, without limitation, the recommendations or advice of any officer or employee of the Company or board of directors of a Subsidiary or such
attorneys, consultants, accountants or other advisors as it may select. All interpretations, determinations, and actions by the Committee shall be final, conclusive, and binding upon all parties. 

3.3 Delegation of Authority. The Committee shall have the right, from time to time, to delegate in writing to one or more officers of
the Company the authority of the Committee to grant and determine the terms and conditions of Awards granted under the Plan, subject to the requirements of Section 157(c) of the Delaware General Corporation Law (or other successor provision),
other applicable law or such other limitations as the Committee shall determine. In 

  
 4 

 
no event shall any such delegation of authority be permitted with respect to Awards granted to any member of the Board or to any Eligible Person who is subject to Rule 16b-3 under the Exchange Act. The Committee shall also be permitted to delegate, to any appropriate officer or employee of the Company, responsibility for performing certain ministerial functions under the Plan. In
the event that the Committee’s authority is delegated to officers or employees in accordance with the foregoing, all provisions of the Plan relating to the Committee shall be interpreted in a manner consistent with the foregoing by treating any
such reference as a reference to such officer or employee for such purpose. Any action undertaken in accordance with the Committee’s delegation of authority hereunder shall have the same force and effect as if such action was undertaken
directly by the Committee and shall be deemed for all purposes of the Plan to have been taken by the Committee. 
 4. Shares Subject to
the Plan. 
 4.1 Number of Shares Reserved. Subject to adjustment as provided in Section 4.3 and Section 4.5
hereof, the total number of shares of Common Stock that are available for issuance under the Plan (the “Share Reserve”) shall equal                .
Within the Share Reserve, the total number of shares of Common Stock available for issuance as Incentive Stock Options shall equal the maximum number of shares available for issuance under the Plan. Each share of Common Stock subject to an Award
shall reduce the Share Reserve by one share. Any shares of Common Stock delivered under the Plan shall consist of authorized and unissued shares or treasury shares. 

4.2 Annual Increase in Shares Reserved. On the first day of each fiscal year of the Company during the term of the Plan, commencing on
January 1, 2023 and ending on (and including) January 1, 2032, the aggregate number of shares of Common Stock that may be issued under the Plan shall automatically increase by a number equal to the least of (i) 5% of the total number of
shares of Common Stock actually issued and outstanding on the last day of the preceding fiscal year, (ii) a number of shares of Common Stock determined by the Board; and
(iii)                shares of Common Stock. 
 4.3 Share
Replenishment. Following the Effective Date, to the extent that an Award granted under this Plan is canceled, expired, repurchased, forfeited, surrendered, exchanged for cash, settled in cash or by delivery of fewer shares of Common Stock than
the number underlying the Award, or otherwise terminated without delivery of the shares of Common Stock to the Participant under the Plan, the unissued shares of Common Stock will (i) not be deemed to have been delivered under the Plan,
(ii) be available for future Awards under the Plan, and (iii) increase the Share Reserve by one share for each share that is retained by or returned to the Company. Shares of Common Stock that are withheld from any Award granted under this
Plan in payment of the exercise, base or purchase price or taxes relating to such an Award shall be available for future Awards under the Plan, and shall increase the Share Reserve by one share for each share that is retained by or returned to the
Company. Shares of Common Stock repurchased by the Company on the open market with the proceeds of an Option, will be deemed to have been delivered under the Plan and will not be available for future Awards under the Plan. The payment of dividend
equivalents in cash in conjunction with any outstanding Award shall not count against the Share Reserve. 

  
 5 

 4.4 Awards Granted to Non-Employee Directors.
No Non-Employee Director may be granted, during any calendar year, Awards having a fair value (determined on the date of grant) that, when added to all cash compensation paid to the Non-Employee Director in respect of the Non-Employee Director’s service as a member of the Board for such calendar year, exceeds (i) $1,000,000 in the year that the
director is first elected to serve as a director on the Board; and (ii) $500,000 in each subsequent year. 
 4.5 Adjustments. If there
shall occur any change with respect to the outstanding shares of Common Stock by reason of any recapitalization, reclassification, stock dividend, extraordinary cash dividend, stock split, reverse stock split or other distribution with respect to
the shares of Common Stock or any merger, reorganization, consolidation, combination, spin-off or other corporate event or transaction or any other change affecting the Common Stock (other than regular cash
dividends to stockholders of the Company), the Committee shall, in the manner and to the extent it considers appropriate and equitable to the Participants and consistent with the terms of the Plan, cause an adjustment to be made to (i) the
maximum number and kind of shares of Common Stock or other securities provided in Sections 4.1 and 4.2 hereof, (ii) the number and kind of shares of Common Stock, units or other securities or rights subject to then outstanding Awards,
(iii) the exercise, base or purchase price for each share or unit or other security or right subject to then outstanding Awards, (iv) other value determinations applicable to the Plan and/or outstanding Awards, and/or (v) any other
terms of an Award that are affected by the event. Notwithstanding the foregoing, (a) any such adjustments shall, to the extent necessary to avoid additional taxes, be made in a manner consistent with the requirements of Section 409A of the
Code and (b) in the case of Incentive Stock Options, any such adjustments shall, to the extent practicable, be made in a manner consistent with the requirements of Section 424(a) of the Code, unless otherwise determined by the Committee.

 5. Eligibility and Awards. 

5.1 Designation of Participants. Any Eligible Person may be selected by the Committee to receive an Award and become a Participant. The
Committee has the authority, in its discretion, to determine and designate from time to time those Eligible Persons who are to be granted Awards, the types of Awards to be granted, the number of shares of Common Stock or units subject to Awards to
be granted and the terms and conditions of such Awards consistent with the terms of the Plan. In selecting Eligible Persons to be Participants, and in determining the type and amount of Awards to be granted under the Plan, the Committee shall
consider any and all factors that it deems relevant or appropriate. Designation of a Participant in any year shall not require the Committee to designate such Person to receive an Award in any other year or, once designated, to receive the same type
or amount of Award as granted to such Participant in any other year. 
 5.2 Determination of Awards. The Committee shall determine the
terms and conditions of all Awards granted to Participants in accordance with its authority under Section 3.2 hereof. An Award may consist of one type of right or benefit hereunder or of two or more such rights or benefits granted in tandem.

  
 6 

 5.3 Award Agreements. Each Award granted to an Eligible Person shall be represented
by an Award Agreement. The terms of the Award, as determined by the Committee, will be set forth in the applicable Award Agreements as described in Section 14.2 hereof. 

6. Stock Options. 
 6.1
Grant of Stock Options. A Stock Option may be granted to any Eligible Person selected by the Committee, except that an Incentive Stock Option may be granted only to an Eligible Person satisfying the conditions of Section 6.7(a) hereof.
Each Stock Option shall be designated on the Date of Grant, in the discretion of the Committee, as an Incentive Stock Option or as a Nonqualified Stock Option. All Stock Options granted under the Plan are intended to comply with or be exempt from
the requirements of Section 409A of the Code, to the extent applicable. 
 6.2 Exercise Price. Unless otherwise determined by the
Committee, the exercise price per share of a Stock Option (other than a Stock Option substituted or assumed under Section 14.10) shall not be less than one hundred percent (100%) of the Fair Market Value of a share of Common Stock on the
Date of Grant. The Committee may in its discretion specify an exercise price per share that is higher than the Fair Market Value of a share of Common Stock on the Date of Grant. 

6.3 Vesting of Stock Options. The Committee shall, in its discretion, prescribe in an award agreement the time or times at which or the
conditions upon which, a Stock Option or portion thereof shall become vested and/or exercisable. The requirements for vesting and exercisability of a Stock Option may be based on the continued Service of the Participant with the Company or a
Subsidiary for a specified time period (or periods), on the attainment of a specified performance goal(s) and/or on such other terms and conditions as approved by the Committee in its discretion. If the vesting requirements of a Stock Option are not
satisfied, the Award shall be forfeited. 
 6.4 Term of Stock Options. The Committee shall in its discretion prescribe in an Award
Agreement the period during which a vested Stock Option may be exercised; provided, however, that the maximum term of a Stock Option shall be ten (10) years from the Date of Grant. If the Fair Market Value of a share of Common
Stock exceeds the Exercise Price on the last day that the Stock Option may be exercised under an Award Agreement, the affected Participant shall be deemed to have exercised the vested portion of such Option in a net exercise under
Section 6.5(ii)(C) below and net share withholding for taxes (unless otherwise agreed) without the requirement of any further action. The Committee may provide that a Stock Option will cease to be exercisable upon or at the end of a specified
time period following a termination of Service for any reason as set forth in the Award Agreement or otherwise. A Stock Option may be earlier terminated as specified by the Committee and set forth in an Award Agreement upon or following the
termination of a Participant’s Service with the Company or any Subsidiary, including by reason of voluntary resignation, death, Disability, termination for Cause or any other reason. Subject to compliance with Section 409A of the Code, as
applicable, and the provisions of this Section 6, the Committee may extend at any time the period in which a Stock Option may be exercised, but not beyond ten (10) years from the Date of Grant. 

  
 7 

 6.5 Stock Option Exercise; Tax Withholding. Subject to such terms and conditions as
specified in an Award Agreement (including applicable vesting requirements), a Stock Option may be exercised in whole or in part at any time during the term thereof by notice in the form required by the Company, together with payment of the
aggregate exercise price and applicable withholding tax. Payment of the exercise price may be made: (i) in cash or by cash equivalent acceptable to the Committee, or, (ii) to the extent permitted by the Committee in its sole discretion in
an Award Agreement or otherwise (A) in shares of Common Stock valued at the Fair Market Value of such shares on the date of exercise, (B) through an open-market, broker-assisted sales transaction pursuant to which the Company is promptly
delivered the amount of proceeds necessary to satisfy the exercise price, (C) by reducing the number of shares of Common Stock otherwise deliverable upon the exercise of the Stock Option by the number of shares of Common Stock having a Fair
Market Value on the date of exercise equal to the exercise price, (D) by a combination of the methods described above or (E) by such other method as may be approved by the Committee. In accordance with Section 14.11 hereof, and in
addition to and at the time of payment of the exercise price, the Participant shall pay to the Company the full amount of any and all applicable income tax, employment tax and other amounts required to be withheld in connection with such exercise,
payable under such of the methods described above for the payment of the exercise price as may be approved by the Committee and set forth in the Award Agreement. 

6.6 Limited Transferability of Nonqualified Stock Options. All Stock Options shall be nontransferable except (i) upon the
Participant’s death, in accordance with Section 14.3 hereof or (ii) in the case of Nonqualified Stock Options only, for the transfer of all or part of the Stock Option to a Participant’s “family member” (as defined for
purposes of the Form S-8 registration statement under the Securities Act), or as otherwise permitted by the Committee to the extent also permitted by the general instructions of the Form S-8 registration statement, as may be amended from time to time, in each case as may be approved by the Committee in its discretion at the time of proposed transfer; provided, in each case, that any permitted
transfer shall be for no consideration. The transfer of a Nonqualified Stock Option may be subject to such terms and conditions as the Committee may in its discretion impose from time to time. Subsequent transfers of a Nonqualified Stock Option
shall be prohibited other than in accordance with Section 14.3 hereof. 
 6.7 Additional Rules for Incentive Stock Options. 

(a) Eligibility. An Incentive Stock Option may be granted only to an Eligible Person who is considered an employee for purposes of
Treasury Regulation Section 1.421-1(h) with respect to the Company or any Subsidiary that qualifies as a “subsidiary corporation” with respect to the Company for purposes of Section 424(f)
of the Code. 

  
 8 

 (b) Annual Limits. No Incentive Stock Option shall be granted to a Participant as a
result of which the aggregate Fair Market Value (determined as of the Date of Grant) of the Common Stock with respect to which incentive stock options under Section 422 of the Code are exercisable for the first time in any calendar year under
the Plan and any other stock option plans of the Company or any Subsidiary or parent corporation, would exceed $100,000, determined in accordance with Section 422(d) of the Code. This limitation shall be applied by taking Stock Options into
account in the order in which granted. Any Stock Option grant that exceeds such limit shall be treated as a Nonqualified Stock Option. 
 (c)
Additional Limitations. In the case of any Incentive Stock Option granted to an Eligible Person who owns, either directly or indirectly (taking into account the attribution rules contained in Section 424(d) of the Code), stock possessing
more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Subsidiary, the exercise price shall not be less than one hundred ten percent (110%) of the Fair Market Value of a share of Common Stock on
the Date of Grant and the maximum term shall be five (5) years. 
 (d) Termination of Service. An Award of an Incentive Stock
Option may provide that such Stock Option may be exercised not later than (i) three (3) months following termination of Service of the Participant with the Company and all Subsidiaries (other than as set forth in clause (ii) of this
Section 6.7(d)) or (ii) one year following termination of Service of the Participant with the Company and all Subsidiaries due to death or permanent and total disability within the meaning of Section 22(e)(3) of the Code, in each case
as and to the extent determined by the Committee to comply with the requirements of Section 422 of the Code. 
 (e) Other Terms and
Conditions; Nontransferability. Any Incentive Stock Option granted hereunder shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as are deemed necessary or desirable by the Committee, which terms,
together with the terms of the Plan, shall be intended and interpreted to cause such Incentive Stock Option to qualify as an “incentive stock option” under Section 422 of the Code. A Stock Option that is granted as an Incentive Stock
Option shall, to the extent it fails to qualify as an “incentive stock option” under the Code, be treated as a Nonqualified Stock Option. An Incentive Stock Option shall by its terms be nontransferable other than by will or by the laws of
descent and distribution, and shall be exercisable during the lifetime of a Participant only by such Participant. 
 (f) Disqualifying
Dispositions. If shares of Common Stock acquired by exercise of an Incentive Stock Option are disposed of within two years following the Date of Grant or one year following the transfer of such shares to the Participant upon exercise, the
Participant shall, promptly following such disposition, notify the Company in writing of the date and terms of such disposition and provide such other information regarding the disposition as the Company may reasonably require. 

6.8 Repricing Prohibited. Subject to the adjustment provisions contained in Section 4.5 hereof and other than in connection with a
Change in Control, without the prior approval of the Company’s stockholders, neither the Committee nor the Board shall cancel a Stock Option when the exercise price per share exceeds the Fair Market Value of one share of Common Stock in
exchange for cash or another Award or cause the cancellation, substitution or amendment of a Stock Option that would have the effect of reducing the exercise price of such a Stock Option previously granted under the Plan or otherwise approve any
modification to such a Stock Option, that would be treated as a “repricing” under the then applicable rules, regulations or listing requirements adopted by the NASDAQ or other principal exchange on which the Common Stock is then listed.

  
 9 

 6.9 No Rights as Stockholder. The Participant shall not have any rights as a
stockholder with respect to the shares underlying a Stock Option until such time as shares or Common Stock are delivered to the Participant pursuant to the terms of the Award Agreement. 

7. Stock Appreciation Rights. 

7.1 Grant of Stock Appreciation Rights. Stock Appreciation Rights may be granted to any Eligible Person selected by the Committee. Stock
Appreciation Rights may be granted on a basis that allows for the exercise of the right by the Participant, or that provides for the automatic exercise or payment of the right upon a specified date or event. Stock Appreciation Rights shall be non-transferable, except as provided in Section 14.3 hereof. All Stock Appreciation Rights granted under the Plan are intended to comply with or otherwise be exempt from the requirements of Section 409A of
the Code, to the extent applicable. 
 7.2 Terms of Stock Appreciation Rights. The Committee shall in its discretion provide in an
Award Agreement the time or times at which or the conditions upon which, a Stock Appreciation Right or portion thereof shall become vested and/or exercisable. If the Fair Market Value of a share of Common Stock exceeds the base price on the last day
that the the Stock Appreciation Right may be exercised under an Award Agreement, the affected Participant shall be deemed to have exercised the vested portion of such Stock Appreciation Right and net share withholding for taxes (unless otherwise
agreed) without the requirement of any further action. The requirements for vesting and exercisability of a Stock Appreciation Right may be based on the continued Service of a Participant with the Company or a Subsidiary for a specified time period
(or periods), on the attainment of a specified performance goal(s) and/or on such other terms and conditions as approved by the Committee in its discretion. If the vesting requirements of a Stock Appreciation Right are not satisfied, the Award shall
be forfeited. A Stock Appreciation Right will be exercisable or payable at such time or times as determined by the Committee; provided, however, that the maximum term of a Stock Appreciation Right shall be ten (10) years from the
Date of Grant. Subject to compliance with Section 409A of the Code, as applicable, and the provisions of this Section 7.2, the Committee may extend at any time the period in which a Stock Appreciation Right may be exercised, but not beyond
ten (10) years from the Date of Grant. The Committee may provide that a Stock Appreciation Right will cease to be exercisable upon or at the end of a period following a termination of Service for any reason. The base price of a Stock
Appreciation Right shall be determined by the Committee in its discretion; provided, however, that the base price per share shall not be less than one hundred percent (100%) of the Fair Market Value of a share of Common Stock on the
Date of Grant (other than with respect to a Stock Appreciation Right substituted or assumed under Section 14.10). 

  
 10 

 7.3 Payment of Stock Appreciation Rights. A Stock Appreciation Right will entitle the
holder, upon exercise or other payment of the Stock Appreciation Right, as applicable, to receive an amount determined by multiplying: (i) the excess of the Fair Market Value of a share of Common Stock on the date of exercise or payment of the
Stock Appreciation Right over the base price of such Stock Appreciation Right, by (ii) the number of shares as to which such Stock Appreciation Right is exercised or paid. Payment of the amount determined under the foregoing may be made, as
approved by the Committee and set forth in the Award Agreement, in shares of Common Stock valued at their Fair Market Value on the date of exercise or payment, in cash or in a combination of shares of Common Stock and cash, subject to applicable tax
withholding requirements. 
 7.4 Repricing Prohibited. Subject to the adjustment provisions contained in Section 4.5 hereof and
other than in connection with a Change in Control, without the prior approval of the Company’s stockholders, neither the Committee nor the Board shall cancel a Stock Appreciation Right when the base price per share exceeds the Fair Market Value
of one share of Common Stock in exchange for cash or another Award or cause the cancellation, substitution or amendment of a Stock Appreciation Right that would have the effect of reducing the base price of such a Stock Appreciation Right previously
granted under the Plan or otherwise approve any modification to such Stock Appreciation Right that would be treated as a “repricing” under the then applicable rules, regulations or listing requirements adopted by the NASDAQ or other
principal exchange on which the Common Stock is then listed. 
 7.5 No Rights as Stockholder. The Participant shall not have any
rights as a stockholder with respect to the shares underlying a Stock Appreciation Right unless and until such time as shares or Common Stock are delivered to the Participant pursuant to the terms of the Award Agreement. 

8. Restricted Stock Awards. 

8.1 Grant of Restricted Stock Awards. A Restricted Stock Award may be granted to any Eligible Person selected by the Committee. The
Committee may require the payment by the Participant of a specified purchase price in connection with any Restricted Stock Award. 
 8.2
Vesting Requirements. The restrictions imposed on shares granted under a Restricted Stock Award shall lapse in accordance with the vesting requirements specified by the Committee in the Award Agreement. The requirements for vesting of a
Restricted Stock Award may be based on the continued Service of the Participant with the Company or a Subsidiary for a specified time period (or periods), on the attainment of a specified performance goal(s) and/or on such other terms and conditions
as approved by the Committee in its discretion. If the vesting requirements of a Restricted Stock Award are not satisfied, the Award shall be forfeited and the shares of Common Stock subject to the Award shall be returned to the Company. 

8.3 Transfer Restrictions. Shares granted under any Restricted Stock Award may not be transferred, assigned or subject to any
encumbrance, pledge or charge until all applicable restrictions are removed or have expired, except as provided in Section 14.3 hereof. Failure to satisfy any applicable restrictions shall result in the subject shares of the Restricted Stock
Award being forfeited and returned to the Company. The Committee may require in an Award Agreement that certificates (if any) representing the shares granted under a Restricted Stock Award bear a legend making appropriate reference to the
restrictions imposed, and that certificates (if any) representing the shares granted or sold under a Restricted Stock Award will remain in the physical custody of an escrow holder until all restrictions are removed or have expired. 

  
 11 

 8.4 Rights as Stockholder. Subject to the foregoing provisions of this Section 8
and the applicable Award Agreement, the Participant shall have all rights of a stockholder with respect to the shares granted to the Participant under a Restricted Stock Award, including the right to vote the shares and receive all dividends and
other distributions paid or made with respect thereto, unless the Committee determines otherwise at the time the Restricted Stock Award is granted. The Committee shall determine and set forth in a Participant’s Award Agreement whether or not a
Participant holding a Restricted Stock Award granted hereunder shall have the right to exercise voting rights with respect to the period during which the Restricted Stock Award is subject to forfeiture (the “Restriction Period”),
and have the right to receive dividends on the Restricted Stock Award during the Restriction Period (and, if so, on what terms) provided that if a Participant has the right to receive dividends paid with respect to the Restricted Stock Award,
such dividends shall be subject to the same vesting terms as the related Restricted Stock Award. 
 8.5 Section 83(b)
Election. If a Participant makes an election pursuant to Section 83(b) of the Code with respect to a Restricted Stock Award, the Participant shall file, within thirty (30) days following the Date of Grant, a copy of such election with
the Company and with the Internal Revenue Service, in accordance with the regulations under Section 83 of the Code. The Committee may provide in an Award Agreement that the Restricted Stock Award is conditioned upon the Participant’s
making or refraining from making an election with respect to the Award under Section 83(b) of the Code. 
 9. Restricted Stock
Units. 
 9.1 Grant of Restricted Stock Units. A Restricted Stock Unit may be granted to any Eligible Person selected by the
Committee. The value of each Restricted Stock Unit is equal to the Fair Market Value of a share of Common Stock on the applicable date or time period of determination, as specified by the Committee. Restricted Stock Units shall be subject to such
restrictions and conditions as the Committee shall determine. Restricted Stock Units shall be non-transferable, except as provided in Section 14.3 hereof. 

9.2 Vesting of Restricted Stock Units. The Committee shall, in its discretion, determine any vesting requirements with respect to
Restricted Stock Units, which shall be set forth in the Award Agreement. The requirements for vesting of a Restricted Stock Unit may be based on the continued Service of the Participant with the Company or a Subsidiary for a specified time period
(or periods), on the attainment of a specified performance goal(s) and/or on such other terms and conditions as approved by the Committee in its discretion. If the vesting requirements of a Restricted Stock Unit Award are not satisfied, the Award
shall be forfeited. 

  
 12 

 9.3 Payment of Restricted Stock Units. Restricted Stock Units shall become payable to
a Participant at the time or times determined by the Committee and set forth in the Award Agreement, which may be upon or following the vesting of the Award. Payment of a Restricted Stock Unit may be made, as approved by the Committee and set forth
in the Award Agreement, in cash or in shares of Common Stock or in a combination thereof, subject to applicable tax withholding requirements. Any cash payment of a Restricted Stock Unit shall be made based upon the Fair Market Value of a share of
Common Stock, determined on such date or over such time period as determined by the Committee. 
 9.4 Dividend Equivalent Rights.
Dividends shall not be paid with respect to Restricted Stock Units. Dividend equivalent rights may be granted with respect to the Shares subject to Restricted Stock Units to the extent permitted by the Committee and set forth in the applicable
Award Agreement; provided that any dividend equivalent rights granted shall be subject to the same vesting terms as the related Restricted Stock Units. 

9.5 No Rights as Stockholder. The Participant shall not have any rights as a stockholder with respect to the shares subject to a
Restricted Stock Unit until such time as shares of Common Stock are delivered to the Participant pursuant to the terms of the Award Agreement. 

10. Stock-Based Awards. 

10.1 Grant of Stock-Based Awards. A Stock-Based Award may be granted to any Eligible Person selected by the Committee. A Stock-Based
Award may be granted for past Services, in lieu of bonus or other cash compensation, as directors’ compensation or for any other valid purpose as determined by the Committee, and shall be based upon or calculated by reference to the Common
Stock. The Committee shall determine the terms and conditions of such Awards, and such Awards may be made without vesting requirements. In addition, the Committee may, in connection with any Stock-Based Award, require the payment of a specified
purchase price. 
 10.2 Rights as Stockholder. The Participant shall not have any rights as a stockholder with respect to the shares
of Common Stock, including the right to vote the shares and receive all dividends and other distributions paid or made with respect thereto, until such time as shares of Common Stock, if any, are issued to the Participant pursuant to the terms of
the Award Agreement. If a Participant has the right to receive dividends paid with respect to the Stock-Based Award, such dividends shall be subject to the same vesting terms as the related Stock-Based Award, if applicable. 

11. Change in Control. 

11.1 Effect on Awards. Upon the occurrence of a Change in Control, all outstanding Awards shall either be (a) continued or assumed
by the Company (if it is the surviving company or corporation) or by the surviving company or corporation or its parent (with such continuation or assumption including conversion into the right to receive securities, cash or a combination of both),
or (b) substituted by the surviving company or corporation or its parent for awards (with such substitution including conversion into the right to receive securities, cash or a combination of both), with substantially similar terms for
outstanding Awards (with appropriate adjustments to the type of consideration payable upon settlement of the Awards or other relevant factors, and 

  
 13 

 
with any applicable performance conditions deemed achieved (i) for any completed performance period, based on actual performance, or (ii) for any partial or future performance period,
at the greater of the target level or actual performance, in each case as determined by the Committee (with the Award remaining subject only to time vesting), unless otherwise provided in an Award Agreement). 

11.2 Certain Adjustments. Notwithstanding Section 11.1, to the extent that outstanding Awards are not continued, assumed or
substituted pursuant to Section 11.1 upon the occurrence of a Change in Control, the Committee is authorized (but not obligated) to make adjustments in the terms and conditions of outstanding Awards, including without limitation the following
(or any combination thereof): 
 (a) acceleration of exercisability, vesting and/or payment of outstanding Awards immediately prior to the
occurrence of such event or upon or following such event; 
 (b) upon written notice, providing that any outstanding Stock Options and Stock
Appreciation Rights are exercisable during a period of time immediately prior to the scheduled consummation of the event or such other period as determined by the Committee (contingent upon the consummation of the event), and at the end of such
period, such Stock Options and Stock Appreciation Rights shall terminate to the extent not so exercised within the relevant period; and 

(c) cancellation of all or any portion of outstanding Awards for fair value (in the form of cash, Common Shares, other property or any
combination thereof) as determined in the sole discretion of the Committee; provided, however, that, in the case of Stock Options and Stock Appreciation Rights or similar Awards, the fair value may equal the excess, if any, of the
value or amount of the consideration to be paid in the Change in Control transaction to holders of shares of Common Stock (or, if no such consideration is paid, Fair Market Value of the shares of Common Stock) over the aggregate exercise or base
price, as applicable, with respect to such Awards or portion thereof being canceled, or if there is no such excess, zero; provided, further, that if any payments or other consideration are deferred and/or contingent as a result of
escrows, earn outs, holdbacks or any other contingencies, payments under this provision may be made on substantially the same terms and conditions applicable to, and only to the extent actually paid to, the holders of Common Shares in connection
with the Change in Control. 
 11.3 Certain Terminations of Service. Notwithstanding the provisions of Section 11.1, if a
Participant’s Service with the Company and its Subsidiaries is terminated upon or within twenty four (24) months following a Change in Control by the Company without Cause or upon such other circumstances as determined by the Committee,
the unvested portion (if any) of all outstanding Awards held by the Participant shall immediately vest (and, to the extent applicable, become exercisable) and be paid in full upon such termination, with any applicable performance conditions deemed
achieved (i) for any completed performance period, based on actual performance, or (ii) for any partial or future performance period, at the greater of the target level or actual performance, in each case as determined by the Committee,
unless otherwise provided in an Award Agreement. 

  
 14 

 11.4 Definition of Change in Control. Unless otherwise defined in an
Award Agreement or other written agreement approved by the Committee, “Change in Control” means, and shall occur, if: 
 (a) any
Person (other than the Company, any trustee or other fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions
as their ownership of shares of Common Stock), is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company
representing more than 50% of the combined voting power of the Company’s then outstanding securities; 
 (b) during any period of two
consecutive years (the “Board Measurement Period”) individuals who at the beginning of such period constitute the Board and any new director (other than a director designated by a Person who has entered into an agreement with the
Company to effect a transaction described in paragraph (a), (c), or (d) of this section, or a director initially elected or nominated as a result of an actual or threatened election contest with respect to directors or as a result of any other
actual or threatened solicitation of proxies by or on behalf of any Person other than the Board) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the Board Measurement Period or whose election or nomination for election was previously so approved, cease for any
reason to constitute at least a majority of the Board; 
 (c) a merger or consolidation of the Company with any other corporation, other than
a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity)
more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; provided, however, that a merger or consolidation effected to implement a
recapitalization of the Company (or similar transaction) in which no Person (other than those covered by the exceptions in (i) above) acquires more than 50% of the combined voting power of the Company’s then outstanding securities shall
not constitute a Change in Control of the Company; or 
 (d) the stockholders of the Company approve the consummation of the sale or
disposition by the Company of all or substantially all of the Company’s assets other than (i) the sale or disposition of all or substantially all of the assets of the Company to a Person or Persons who beneficially own, directly or
indirectly, more than 50% of the combined voting power of the outstanding voting securities of the Company at the time of the sale or disposition or (ii) pursuant to a spinoff type transaction, directly or indirectly, of such assets to the
stockholders of the Company. 
 Notwithstanding the foregoing, to the extent necessary to comply with Section 409A of the Code with respect to the
payment of “nonqualified deferred compensation,” “Change in Control” shall be limited to a “change in control event” as defined under Section 409A of the Code. 

  
 15 

 12. Forfeiture Events. 

12.1 General. The Committee may specify in an Award Agreement that the Participant’s rights, payments and benefits with respect to
an Award are subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, without
limitation, termination of Service for Cause, violation of laws, regulations or material Company policies, breach of noncompetition, non-solicitation, confidentiality or other restrictive covenants that may
apply to the Participant, application of a Company clawback policy relating to financial restatement, or other conduct by the Participant that is detrimental to the business or reputation of the Company. 

12.2 Termination for Cause. 

(a) Treatment of Awards. Unless otherwise provided by the Committee and set forth in an Award Agreement, if (i) a
Participant’s Service with the Company or any Subsidiary shall be terminated for Cause or (ii) after termination of Service for any other reason, the Committee determines in its discretion either that, (1) during the
Participant’s period of Service, the Participant engaged in an act or omission which would have warranted termination of Service for Cause or (2) after termination, the Participant engages in conduct that violates any continuing obligation
or duty of the Participant in respect of the Company or any Subsidiary, such Participant’s rights, payments and benefits with respect to an Award shall be subject to cancellation, forfeiture and/or recoupment, as provided in Section 12.3
below. The Company shall have the power to determine whether the Participant has been terminated for Cause, the date upon which such termination for Cause occurs, whether the Participant engaged in an act or omission which would have warranted
termination of Service for Cause or engaged in conduct that violated any continuing obligation or duty of the Participant in respect of the Company or any Subsidiary. Any such determination shall be final, conclusive and binding upon all Persons. In
addition, if the Company shall reasonably determine that a Participant has committed or may have committed any act which could constitute the basis for a termination of such Participant’s Service for Cause or violates any continuing obligation
or duty of the Participant in respect of the Company or any Subsidiary, the Company may suspend the Participant’s rights to exercise any Stock Option or Stock Appreciation Right, receive any payment or vest in any right with respect to any
Award pending a determination by the Company of whether an act or omission could constitute the basis for a termination for Cause as provided in this Section 12.2. 

(b) Definition of Cause. “Cause” means with respect to a Participant’s termination of Service, the following:
(a) in the case where there is no employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate and the Participant (or where there is such an agreement but it does
not define “cause” (or words of like import, which shall include but not be limited to “gross misconduct”)), termination due to a Participant’s (1) failure to substantially perform Participant’s duties or obey
lawful directives that continues after receipt of written notice from the Company and a 10-day opportunity to cure; (2) gross misconduct or gross negligence in the performance of Participant’s
duties; (3) fraud, embezzlement, theft, or any other act of material dishonesty or 

  
 16 

 
misconduct; (4) conviction of, indictment for, or plea of guilty or nolo contendere to, a felony or any crime involving moral turpitude; (5) material breach or violation of any
agreement with the Company or its Affiliates, any restrictive covenant applicable to Participant, or any Company policy (including, without limitation, with respect to harassment); or (6) other conduct, acts or omissions that, in the good faith
judgment of the Company, are likely to materially injure the reputation, business or a business relationship of the Company or any of its Affiliates; or (b) in the case where there is an employment agreement, consulting agreement, change in
control agreement or similar agreement in effect between the Company or an Affiliate and the Participant that defines “cause” (or words of like import, which shall include but not be limited to “gross misconduct”),
“cause” as defined under such agreement. With respect to a termination of Service for a non-employee director, Cause means an act or failure to act that constitutes cause for removal of a director
under applicable law. Any voluntary termination of Service by the Participant in anticipation of an involuntary termination of the Participant’s Service for Cause shall be deemed to be a termination for Cause. 

12.3 Right of Recapture. 

(a) General. If at any time within one year (or such longer time specified in an Award Agreement or other agreement with a Participant
or policy applicable to the Participant) after the date on which a Participant exercises a Stock Option or Stock Appreciation Right or on which a Stock-Based Award, Restricted Stock Award or Restricted Stock Unit vests, is settled in shares or
otherwise becomes payable, or on which income otherwise is realized or property is received by a Participant in connection with an Award, (i) a Participant’s Service is terminated for Cause, (ii) the Committee determines in its
discretion that the Participant is subject to any recoupment of benefits pursuant to the Company’s compensation recovery, “clawback” or similar policy, as may be in effect from time to time, or (iii) after a Participant’s
Service terminates for any other reason, the Committee determines in its discretion either that, (1) during the Participant’s period of Service, the Participant engaged in an act or omission which would have warranted termination of the
Participant’s Service for Cause or (2) after a Participant’s termination of Service, the Participant engaged in conduct that violated any continuing obligation or duty of the Participant in respect of the Company or any Subsidiary,
then, at the sole discretion of the Committee, any gain realized by the Participant from the exercise, vesting, payment, settlement or other realization of income or receipt of property by the Participant in connection with an Award, shall be repaid
by the Participant to the Company upon notice from the Company, subject to applicable law. Such gain shall be determined as of the date or dates on which the gain is realized by the Participant, without regard to any subsequent change in the Fair
Market Value of a share of Common Stock. To the extent not otherwise prohibited by law, the Company shall have the right to offset the amount of such repayment obligation against any amounts otherwise owed to the Participant by the Company (whether
as wages, vacation pay or pursuant to any benefit plan or other compensatory arrangement). 
 (b) Accounting Restatement. If a
Participant receives compensation pursuant to an Award under the Plan based on financial statements that are subsequently restated in a way that would decrease the value of such compensation, the Participant will, to the extent not otherwise
prohibited by law, upon the written request of the Company, forfeit and repay to the Company the difference between what the Participant received and what the Participant should 

  
 17 

 
have received based on the accounting restatement, in accordance with (i) any compensation recovery, “clawback” or similar policy, as may be in effect from time to time to which
such Participant is subject and (ii) any compensation recovery, “clawback” or similar policy made applicable by law including the provisions of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the
rules, regulations and requirements adopted thereunder by the Securities and Exchange Commission and/or any national securities exchange on which the Company’s equity securities may be listed (the “Policy”). By accepting an
Award hereunder, the Participant acknowledges and agrees that the Policy, whenever adopted, shall apply to such Award, and all incentive-based compensation payable pursuant to such Award shall be subject to forfeiture and repayment pursuant to the
terms of the Policy. 
 13. Transfer, Leave of Absence, Etc. For purposes of the Plan, except as otherwise determined by the
Committee, the following events shall not be deemed a termination of Service: (a) a transfer to the service of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another; or (b) an approved leave
of absence for military service or sickness, a leave of absence where the employee’s right to re-employment is protected either by a statute or by contract or under the policy pursuant to which the leave
of absence was granted, a leave of absence for any other purpose approved by the Company or if the Committee otherwise so provides in writing. 

14. General Provisions. 

14.1 Status of Plan. The Committee may authorize the creation of trusts or other arrangements to meet the Company’s obligations to
deliver shares of Common Stock or make payments with respect to Awards. 
 14.2 Award Agreement. An Award under the Plan shall be
evidenced by an Award Agreement in a written or electronic form approved by the Committee setting forth the number of shares of Common Stock or other amounts or securities subject to the Award, the exercise price, base price or purchase price of the
Award, the time or times at which an Award will become vested, exercisable or payable and the term of the Award. The Award Agreement also may set forth the effect on an Award of a Change in Control and/or a termination of Service under certain
circumstances. The Award Agreement shall be subject to and incorporate, by reference or otherwise, all of the applicable terms and conditions of the Plan, and also may set forth other terms and conditions applicable to the Award as determined by the
Committee consistent with the limitations of the Plan. The grant of an Award under the Plan shall not confer any rights upon the Participant holding such Award other than such terms, and subject to such conditions, as are specified in the Plan as
being applicable to such type of Award (or to all Awards) or as are expressly set forth in the Award Agreement. The Committee need not require the execution of an Award Agreement by a Participant, in which case, acceptance of the Award by the
Participant shall constitute agreement by the Participant to the terms, conditions, restrictions and limitations set forth in the Plan and the Award Agreement as well as the administrative guidelines of the Company in effect from time to time. In
the event of any conflict between the provisions of the Plan and any Award Agreement, the provisions of the Plan shall prevail. 

  
 18 

 14.3 No Assignment or Transfer; Beneficiaries. Except as provided in Section 6.6
hereof or as otherwise provided by the Committee to the extent not prohibited under Section A.1.(5) of the general instructions of Form S-8, as may be amended from time to time, Awards under the Plan shall not
be assignable or transferable by the Participant, and shall not be subject in any manner to assignment, alienation, pledge, encumbrance or charge. Notwithstanding the foregoing, in the event of the death of a Participant, except as otherwise
provided by the Committee, an outstanding Award may be exercised by or shall become payable to the Participant’s beneficiary as determined under the Company 401(k) retirement plan or other applicable retirement or pension plan. In lieu of such
determination, a Participant may, from time to time, name any beneficiary or beneficiaries to receive any benefit in case of the Participant’s death before the Participant receives any or all of such benefit. Each such designation shall revoke
all prior designations by the same Participant and will be effective only when filed by the Participant in writing (in such form or manner as may be prescribed by the Committee) with the Company during the Participant’s lifetime. In the absence
of a valid designation as provided above, if no validly designated beneficiary survives the Participant or if each surviving validly designated beneficiary is legally impaired or prohibited from receiving the benefits under an Award, the
Participant’s beneficiary shall be the legatee or legatees of such Award designated under the Participant’s last will or by such Participant’s executors, personal representatives or distributees of such Award in accordance with the
Participant’s will or the laws of descent and distribution. The Committee may provide in the terms of an Award Agreement or in any other manner prescribed by the Committee that the Participant shall have the right to designate a beneficiary or
beneficiaries who shall be entitled to any rights, payments or other benefits specified under an Award following the Participant’s death. Any transfer permitted under this Section 14.3 shall be for no consideration. 

14.4 No Right to Employment or Continued Service. Nothing in the Plan, in the grant of any Award or in any Award Agreement shall confer
upon any Eligible Person or any Participant any right to continue in the Service of the Company or any of its Subsidiaries or interfere in any way with the right of the Company or any of its Subsidiaries to terminate the employment or other service
relationship of an Eligible Person or a Participant for any reason or no reason at any time. 
 14.5 Rights as Stockholder. A
Participant shall have no rights as a holder of shares of Common Stock with respect to any unissued securities covered by an Award until the date the Participant becomes the holder of record of such securities. Except as provided in Section 4.5
hereof, no adjustment or other provision shall be made for dividends or other stockholder rights, except to the extent that the Award Agreement provides for dividend payments or dividend equivalent rights. The Committee may determine in its
discretion the manner of delivery of Common Stock to be issued under the Plan, which may be by delivery of stock certificates, electronic account entry into new or existing accounts or any other means as the Committee, in its discretion, deems
appropriate. The Committee may require that the stock certificates (if any) be held in escrow by the Company for any shares of Common Stock or cause the shares to be legended in order to comply with the securities laws or other applicable
restrictions. Should the shares of Common Stock be represented by book or electronic account entry rather than a certificate, the Committee may take such steps to restrict transfer of the shares of Common Stock as the Committee considers necessary
or advisable. 

  
 19 

 14.6 Trading Policy and Other Restrictions. Transactions involving Awards under the
Plan shall be subject to the Company’s insider trading and other restrictions, terms, conditions and policies, established by the Committee from time to time or by applicable law. 

14.7 Section 409A Compliance. To the extent applicable, it is intended that the Plan and all Awards hereunder comply
with, or be exempt from, the requirements of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder, and that the Plan and all Award Agreements shall be interpreted and applied by the Committee in a manner
consistent with this intent in order to avoid the imposition of any additional tax under Section 409A of the Code. In the event that any (i) provision of the Plan or an Award Agreement, (ii) Award, payment, transaction or
(iii) other action or arrangement contemplated by the provisions of the Plan is determined by the Committee to not comply with the applicable requirements of Section 409A of the Code and the Treasury Regulations and other guidance issued
thereunder, the Committee shall have the authority to take such actions and to make such changes to the Plan or an Award Agreement as the Committee deems necessary to comply with such requirements. No payment that constitutes deferred compensation
under Section 409A of the Code that would otherwise be made under the Plan or an Award Agreement upon a termination of Service will be made or provided unless and until such termination is also a “separation from service,” as
determined in accordance with Section 409A of the Code. Notwithstanding the foregoing or anything elsewhere in the Plan or an Award Agreement to the contrary, if a Participant is a “specified employee” as defined in Section 409A
of the Code at the time of termination of Service with respect to an Award, then solely to the extent necessary to avoid the imposition of any additional tax under Section 409A of the Code, the commencement of any payments or benefits under the
Award shall be deferred until the date that is six (6) months plus one (1) day following the date of the Participant’s termination of Service or, if earlier, the Participant’s death (or such other period as required to comply
with Section 409A). For purposes of Section 409A of the Code, a Participant’s right to receive any installment payments pursuant to this Plan or any Award granted hereunder shall be treated as a right to receive a series of separate
and distinct payments. For the avoidance of doubt, each applicable tranche of Common Shares subject to vesting under any Award shall be considered a right to receive a series of separate and distinct payments. In no event whatsoever shall the
Company be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 409A of the Code or any damages for failing to comply with Section 409A of the Code. 

14.8 Section 457A Compliance. In the event any Award is subject to Section 457A of the Code
(“Section 457A”), the Committee may, in its sole discretion and without a Participant’s prior consent, amend the Plan and/or Awards, adopt policies and procedures, or take any other actions (including
amendments, policies, procedures and actions with retroactive effect) as are necessary or appropriate to (i) exempt the Plan and/or any Award from the application of Section 457A, (ii) preserve the intended tax treatment of any such
Award, or (iii) comply with the requirements of Section 457A, including without limitation any such regulations, guidance, compliance programs and other interpretative authority that may be issued after the date of the grant. To the extent
that an Award constitutes deferred compensation subject to Section 457A, such Award will be subject to taxation in accordance with Section 457A. In no event whatsoever shall the Company be liable for any additional tax, interest or
penalties that may be imposed on a Participant by Section 457A of the Code or any damages for failing to comply with Section 457A of the Code. 

  
 20 

 14.9 Securities Law Compliance. No shares of Common Stock will be issued or
transferred pursuant to an Award unless and until all then applicable requirements imposed by Federal and state securities and other laws, rules and regulations and by any regulatory agencies having jurisdiction, and by any exchanges upon which the
shares of Common Stock may be listed, have been fully met. As a condition precedent to the issuance of shares of Common Stock pursuant to the grant or exercise of an Award, the Company may require the Participant to take any action that the Company
determines is necessary or advisable to meet such requirements. The Committee may impose such conditions on any shares of Common Stock issuable under the Plan as it may deem advisable, including, without limitation, restrictions under the Securities
Act, under the requirements of any exchange upon which such shares of the same class are then listed, and under any blue sky or other securities laws applicable to such shares. The Committee may also require the Participant to represent and warrant
at the time of issuance or transfer that the shares of Common Stock are being acquired solely for investment purposes and without any current intention to sell or distribute such shares. 

14.10 Substitution or Assumption of Awards in Corporate Transactions. The Committee may grant Awards under the Plan in connection with
the acquisition, whether by purchase, merger, consolidation or other corporate transaction, of the business or assets of any corporation or other entity, in substitution for awards previously granted by such corporation or other entity or otherwise.
The Committee may also assume any previously granted awards of a former employee or a current employee, director, consultant or other service provider of another corporation or entity that becomes an Eligible Person by reason of such corporation
transaction. The terms and conditions of the substituted or assumed awards may vary from the terms and conditions that would otherwise be required by the Plan solely to the extent the Committee deems necessary for such purpose. To the extent
permitted by applicable law and the listing requirements of the NASDAQ or other exchange or securities market on which the Common Shares are listed, any such substituted or assumed awards shall not reduce the Share Reserve. 

14.11 Tax Withholding. The Participant shall be responsible for payment of any taxes or similar charges required by law to be paid or
withheld from an Award or an amount paid in satisfaction of an Award. Any required withholdings shall be paid by the Participant on or prior to the payment or other event that results in taxable income in respect of an Award. The Award Agreement may
specify the manner in which the withholding obligation shall be satisfied with respect to the particular type of Award, which may include permitting the Participant to elect to satisfy the withholding obligation by tendering shares of Common Stock
to the Company or having the Company withhold a number of shares of Common Stock having a value in each case up to the maximum statutory tax rates in the applicable jurisdiction or as the Committee may approve in its discretion (provided that such
withholding does not result in adverse tax or accounting consequences to the Company), or similar charge required to be paid or withheld. In addition, to the extent permitted by the Committee in its sole discretion in an Award Agreement or
otherwise, and subject to Section 16 of the Securities Act, withholding may be satisfied through an open-market, broker-assisted sales transaction pursuant to which the Company is promptly delivered the amount of proceeds necessary to satisfy
the withholding amount, which 

  
 21 

 
shall be subject to any terms and conditions imposed by the Committee. The Company shall have the power and the right to require a Participant to remit to the Company the amount necessary to
satisfy federal, state, provincial and local taxes, domestic or foreign, required by law or regulation to be withheld, and to deduct or withhold from any shares of Common Stock deliverable under an Award to satisfy such withholding obligation. 

14.12 Unfunded Plan. The adoption of the Plan and any reservation of shares of Common Stock or cash amounts by the Company to discharge
its obligations hereunder shall not be deemed to create a trust or other funded arrangement. Except upon the issuance of shares of Common Stock pursuant to an Award, any rights of a Participant under the Plan shall be those of a general unsecured
creditor of the Company, and neither a Participant nor the Participant’s permitted transferees or estate shall have any other interest in any assets of the Company by virtue of the Plan. Notwithstanding the foregoing, the Company shall have the
right to implement or set aside funds in a grantor trust, subject to the claims of the Company’s creditors or otherwise, to discharge its obligations under the Plan. 

14.13 Other Compensation and Benefit Plans. The adoption of the Plan shall not affect any other share incentive or other compensation
plans in effect for the Company or any Subsidiary, nor shall the Plan preclude the Company from establishing any other forms of share incentive or other compensation or benefit program for employees of the Company or any Subsidiary. The amount of
any compensation deemed to be received by a Participant pursuant to an Award shall not constitute includable compensation for purposes of determining the amount of benefits to which a Participant is entitled under any other compensation or benefit
plan or program of the Company or a Subsidiary, including, without limitation, under any pension or severance benefits plan, except to the extent specifically provided by the terms of any such plan. 

14.14 Plan Binding on Transferees. The Plan shall be binding upon the Company, its transferees and assigns, and the Participant, the
Participant’s executor, administrator and permitted transferees and beneficiaries. 
 14.15 Severability. If any provision of the
Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions
shall remain enforceable in any other jurisdiction. 
 14.16 Governing Law. The Plan, all Awards and all Award Agreements, and all
claims or causes of action (whether in contract, tort or statute) that may be based upon, arise out of or relate to the Plan, any Award or Award Agreement, or the negotiation, execution or performance of any such documents or matter related thereto
(including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with the Plan, any Award or Award Agreement, or as an inducement to enter into any Award Agreement), shall be
governed by, and enforced in accordance with, the internal laws of the State of Delaware, including its statutes of limitations and repose, but without regard to any borrowing statute that would result in the application of the statute of
limitations or repose of any other jurisdiction. 

  
 22 

 14.17 No Fractional Shares. No fractional shares of Common Stock shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional shares of Common Stock or whether such fractional shares or any
rights thereto shall be canceled, terminated or otherwise eliminated.

AIDH TOPCO, LLC 
 2019
EQUITY INCENTIVE PLAN 
 TOPCO CLASS B UNIT GRANT AGREEMENT 

THIS CLASS B UNIT GRANT AGREEMENT (the “Agreement”) is made as of September 18, 2019 (the “Grant Date”) among AIDH
Topco, LLC, a Delaware limited liability company (the “Company”), AIDH Management Holdings, LLC a Delaware limited liability company (the “Participant”), and (the “Service Provider”). 

R E C I T A L S 
 A. The
Company is governed by the Amended and Restated Limited Liability Company Agreement of AIDH Topco, LLC, dated as of July 16, 2019 (as the same may be further amended, restated, modified or otherwise supplemented from time-to-time, the “LLC Agreement”). Capitalized terms not otherwise defined in this Agreement shall have the meanings ascribed to such terms in the LLC
Agreement. 
 B. In consideration for the provisions of services to or for the benefit of the Company, including through the provision of
services to its Subsidiaries and Affiliates, by the Participant and Service Provider, the Company hereby grants Class B Units to the Participant under the terms and provisions of this Agreement, the AIDH Topco, LLC 2019 Equity Incentive Plan
(the “Plan”) and the LLC Agreement. 
 C. The Company and the Participant desire to impose certain vesting conditions with
respect to the Class B Units granted to the Participant. 
 D. Following the execution of this Agreement, the Participant and the
Service Provider will enter into a grant agreement pursuant to which the Participant will grant a corresponding number of Class B Units of the Participant (the “Participant Class B Units”) to the Service
Provider. 
 A G R E E M E N T S 

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company, the
Participant and the Service Provider agree as follows: 
 ARTICLE I. 

GRANT OF CLASS B UNITS 

1.1 Grant. Subject to the terms and conditions contained herein and in the Plan and LLC Agreement, the Participant is
granted Class B Units of the Company, of which shall be eligible to vest based on the passage of time (the “Time Vesting Units”) and shall be eligible to vest based on the achievement of certain performance goals (the
“Performance Vesting Units”). 

 1.2 Risks. The Participant is aware of and understands the following:

 (a) the Participant must bear the economic risk of an investment in the Class B Units for an indefinite period of time because, among
other things, (i) the Class B Units have not been registered under the Securities Act, and, therefore, cannot be sold unless they are subsequently registered under the Securities Act or an exemption from such registration is available,
(ii) the Class B Units have not been registered under applicable state securities laws, and, therefore, cannot be sold unless they are registered under applicable state securities laws or an exemption from such registration is available,
and (iii) there are substantial restrictions on the transferability of the Class B Units under this Agreement, the Plan, the LLC Agreement and applicable law, and substantial restrictions on distributions from the Company; 

(b) there is no established market for the Class B Units and no market (public or otherwise) for the Class B Units will develop in
the foreseeable future; and 
 (c) except as provided in the LLC Agreement, the Participant has no rights to require that the Class B
Units be registered under the Securities Act or the securities laws of any states and the Participant will not be able to avail itself of the provisions of Rule 144 adopted by the Securities and Exchange Commission under the Securities Act. 

1.3 Protective Section 83(b) Election. Within thirty (30) days from the date
hereof, the Participant shall execute and file with the Internal Revenue Service a protective election under Section 83(b) of the Code and the regulations promulgated thereunder (an “83(b) Election”) with respect to the grant
of Class B Units described in this Agreement substantially in the form attached hereto as Exhibit A and the Participant shall provide the Company with a copy of such executed and filed 83(b) Election promptly thereafter. The Participant
hereby acknowledges that (i) the Company has not provided, and is not hereby providing, the Participant with tax advice regarding the 83(b) Election and has urged the Participant to consult his own tax advisor with respect to the income
taxation consequences thereof, and (ii) the Company will have no liability to the Participant if the actual fair market value of the Class B Units on the date hereof exceeds the amount specified in the 83(b) Election. 

ARTICLE II. 
 PROFITS
INTERESTS; VESTING 
 2.1 Profits Interests. The Class B Units granted under this Agreement are intended to constitute
“profits interests” as described in Section 3.3 of the LLC Agreement and shall be subject to the terms and conditions thereof. 
 2.2
Hurdle Amount. The Hurdle Amount for the Class B Units being granted to the Participant pursuant to this Agreement is equal to $0.00, such amount being determined by the Board as of the Grant Date pursuant the LLC Agreement;
provided, that the Hurdle Amount shall, in any event, be consistent with the intended characterization of the Class B Units being granted hereunder as a “profits interest.” 

2.3 Vesting of Class B Units. The Class B Units being granted to the Participant hereunder shall
vest and become Vested Class B Units as provided in this Section 2.3: 
 (a) Time Vesting Units. 

  
 2 

 (i) Vesting. Subject to the remainder of this
Section 2.3(a), 25% of the Time Vesting Units shall become Vested Class B Units on each of the first four (4) anniversaries of the Vesting Commencement Date such that one hundred percent (100%) of the Time Vesting
Units will be Vested Class B Units on the fourth (4th) anniversary of the Vesting Commencement Date, subject, in each case, to the Service Provider’s continued Service from the date of this Agreement through the applicable vesting date.
For purposes of this Agreement, the “Vesting Commencement Date” shall mean July 16, 2019. 
 (ii) Change in Control.
Upon the consummation of a Change in Control, one hundred percent (100%) of the Participant’s Time Vesting Units that remain unvested shall become Vested Class B Units as of immediately prior to such Change in Control, subject to the
Service Provider’s continued Service on the date of the Change in Control. 
 (b) Performance Vesting Units. 

(i) Vesting. The Performance Vesting Units shall become Vested Class B Units, as set forth below: 

A. One-third of the Performance Vesting Units shall become Vested Class B Units
upon a Change in Control in which Advent achieves a MOIC equal to at least two (2), subject to the Service Provider’s continued Service through such Change in Control; 

B. One-third of the Performance Vesting Units shall become Vested Class B Units
upon a Change in Control in which Advent achieves a MOIC of at least two and one-half (2.5), subject to the Service Provider’s continued Service through such Change in Control; and 

C. One-third of the Performance Vesting Units shall become Vested Class B Units
upon a Change in Control in which Advent achieves a MOIC of at least three (3), subject to the Service Provider’s continued Service through such Change in Control. 

D. If upon a Change in Control, Advent achieves a MOIC between two (2) and two and
one-half (2.5) or two and one-half (2.5) and three (3), the number of Performance Vesting Units that become Vested Class B Units under clause (B) or (C) above,
respectively, shall be determined by linear interpolation. For the avoidance of doubt, no Performance Vesting Units shall become Vested Class B Units if Advent does not achieve a MOIC equal to at least two (2). 

(ii) Change in Control. Any Performance Vesting Units that have not become Vested Class B Units upon a Change in Control (after
taking into account Performance Vesting Units that vest in connection with such Change in Control) shall be forfeited without consideration paid therefor. 

  
 3 

 (iii) Calculation of MOIC. It is understood and agreed that in the event of the
receipt by Advent of any distribution or any transaction in which Advent will receive Advent Cash Amounts, then the calculations described for the MOIC shall be made on an “as if” basis prior to the actual receipt of such amounts and the
outstanding Performance Vesting Units of the Participant shall become Vested Class B Units immediately prior to a Change in Control on the basis of the amounts actually to be received by Advent in such distribution or transaction (including
after giving effect to vesting of Performance Vesting Units as a result thereof under this paragraph, but not taking into account Advent Cash Amounts that have not yet been received) and the Participant shall be entitled to participate in such
distribution or transaction as to such Vested Class B Units. As a result, the calculations described above shall be made in terms of amounts to be received by Advent and the portion of the Performance Vesting Units that will become Vested
Class B Units able to participate in a distribution or transaction, all computed on an “after vesting” basis as to such Class B Units. 

(iv) Initial Public Offering. Subject to the Service Provider’s continued Service through the consummation of an Initial Public
Offering, any Performance Vesting Units that would vest pursuant to Sections 2.3(b)(i) through of this Agreement if Deemed IPO Cash Amounts were included as Advent Cash Amounts shall be converted to an award of restricted Successor Shares as
to which Section 2.3(a)(ii), Section 3.1 and Section 3.2 of this Agreement shall apply mutatis mutandis (the “IPO Awards”), and any such
Performance Vesting Units that would not vest if the Deemed IPO Cash Amounts were included as Advent Cash Amounts shall be forfeited without consideration paid therefor upon the IPO. One-third (1/3) of the IPO
Awards shall vest on the first (1st) anniversary of the Initial Public Offering, one-third (1/3) of the IPO Awards shall vest on the second (2nd) anniversary of the Initial Public Offering and one-third (1/3) of the IPO Awards shall vest on the third (3rd) anniversary of the Initial Public Offering, subject to the Service Provider’s continued Service through the applicable vesting date. 

ARTICLE III. 
 FORFEITURE
OF CLASS B UNITS 
 3.1 Forfeiture of Performance Vesting Units and Time Vesting Units. All Performance Vesting Units and Time
Vesting Units that have not vested as of the date of termination of the Service Provider’s Service, shall expire and immediately be forfeited and canceled in their entirety without any consideration to the Participant. 

3.2 Forfeiture of Vested Class B Units. Upon (i) a termination of the Service Provider’s
Service for Cause, (ii) resignation by the Service Provider when grounds for Cause exist or (iii) if the Service Provider materially breaches any restrictive covenants contained in Section 5.1 or any other
restrictive covenants contained in an agreement between the Service Provider and the Company or its Subsidiaries (subject to any applicable cure rights), then all Vested Class B Units shall expire and immediately be forfeited and cancelled in
their entirety without any consideration to the Participant.

 RESTRICTIVE
COVENANTS 
 5.1 Restrictive Covenants. In consideration for the Class B Units granted to the Participant by the Company under
this Agreement and the Participant Class B Units granted to the Service Provider, and for the Service Provider’s access to and receipt of the confidential information and trade secrets described herein, the Service Provider agrees to be
bound by the following covenants; provided that, if the Service Provider is subject to restrictive covenants under any other agreement, including, but not limited to, an applicable employment agreement, then the most restrictive of the restrictive
covenants shall apply to the Service Provider. 
 (a) Non-Solicitation. During the term of
the Service Provider’s employment with the Company or one of Subsidiaries (the “Employment Term”) and for a period of two years thereafter, the Service Provider agrees that the Service Provider will not, except in the furtherance of
the Service Provider’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other entity, solicit, aid or induce any employee of the Company or any of its Subsidiaries or Affiliates at
the time of such action to leave such employment or to accept employment with or render services to or with any other person, firm, corporation or other entity unaffiliated with the Company or hire or retain any such employee, or take any action to

  
 7 

 
materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such employee. An employee shall be deemed covered by this sub-section while so employed or retained and for six months thereafter. Notwithstanding the foregoing, the provisions of this sub-section shall not be violated by general
advertising or solicitation not specifically targeted at employees of the Company or any of its Subsidiaries or Affiliates; provided, that such general advertising or solicitation does not result in the hiring of any employee that the Service
Provider otherwise would be prohibited from hiring under this Section 5.1. 
 (b)
Non-Competition. During the Employment Term and for a period of one year thereafter, the Service Provider agrees that the Service Provider will not directly or indirectly provide services, of the type
provided by the Service Provider to the Company at any time during the last two years of the Employment Term, whether as an owner, officer, director, partner, member, employee, agent, consultant, advisor or developer or in any similar capacity, to
any other business entity that is engaged or seeks to become engaged in any line of business conducted by the Company or its Subsidiaries, or which the Company or its Subsidiaries have active plans to conduct, as of the termination of the Service
Provider’s employment, in each case, in any state of the United States and any country outside the United States in which the Company or any of its Subsidiaries conducts its business, in which the Service Provider, during any time within the
last two (2) years of employment, provided services or had a material presence or influence (provided that the Service Provider shall not be prohibited from owning up to five percent (5%) of the outstanding stock of a corporation which is
publicly traded, so long as the Service Provider has no active participation in the business of such corporation). The post-employment restrictions in this Section 5.1(b) shall not apply in the case of a termination of the Service
Provider’s employment by the Company without Cause or as part of a workforce reduction. The Service Provider acknowledges and agrees that the Class B Units granted to the Service Provider by the Company under this Agreement constitute fair
and reasonable, mutually agreed upon consideration for the restrictions contained in this Agreement, including, without limitation, in this Section 5.1(b). If the Service Provider has unlawfully taken, physically or electronically, property
belonging to the Company, or has breached any fiduciary duties owed to the Company, the duration of the post-employment restrictions in this Section 5.1(b) shall be extended to two years following the termination of the Service Provider’s
employment. The Service Provider acknowledges that he or she has been provided notice of this Section 5.1(b) at least 10 business days prior to this Agreement becoming effective, and that he or she has the right to consult with counsel prior to
signing this Agreement. 
 (c) Confidentiality. The Service Provider acknowledges that during the Employment Term, the Service
Provider shall have access to and shall be provided with sensitive, confidential, proprietary, business, technical, data and other trade secret information of the Company that is the property of the Company, and the Service Provider agrees that the
Company has a protectable interest in such property. The Service Provider agrees that the Service Provider shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of the
Service Provider’s assigned duties and for the benefit of the Company or to Service Provider’s personal advisors for purposes of enforcing or interpreting this Agreement, during the Service Provider’s employment with the Company or
one of its Subsidiaries and at all times thereafter, any business and technical information, nonpublic, proprietary or confidential information, knowledge or data relating to the Company, any of its Subsidiaries or its Affiliates, which shall have
been obtained by the Service Provider during the 

  
 8 

 
Service Provider’s employment by the Company or one of its Subsidiaries (or any predecessor). The foregoing shall not apply to information that (i) was known to the public prior to its
disclosure to the Service Provider; (ii) becomes generally known to the public subsequent to disclosure to the Service Provider through no wrongful act of the Service Provider or any representative of the Service Provider; or (iii) the
Service Provider is required to disclose by applicable law, regulation or legal process (provided that, to the extent not prohibited by applicable law, the Service Provider provides the Company with prior notice of the contemplated disclosure and
cooperates with the Company at its expense in seeking a protective order or other appropriate protection of such information). Notwithstanding anything in this provision to the contrary, the Service Provider shall not, directly or indirectly, use,
make available, sell, disclose or otherwise communicate to any person, other than in the course of the Service Provider’s assigned duties and for the benefit of the Company, either during the period of the Service Provider’s employment or
at any time thereafter, any information or data that constitutes a trade secret as defined by applicable law. Nothing in this provision shall be construed to prohibit the Service Provider from disclosing any such information to the Company’s
Affiliates provided that the Service Provider takes reasonable measures to ensure the continued confidentiality and trade secret status of such information. Notwithstanding anything herein to the contrary, the Service Provider’s confidentiality
obligations in this Section 5.1(c) shall not be applied to limit or interfere with the Service Provider’s right, without notice to or authorization of the Company, to communicate and cooperate in good faith with a Governmental Agency for
the purpose of (A) reporting a possible violation of any U.S. federal, state, or local law or regulation, (B) participating in any investigation or proceeding that may be conducted or managed by any Government Agency, including by
providing documents or other information, or (C) filing a charge or complaint with a Government Agency. For purposes of this Agreement, “Government Agency” means the Equal Employment Opportunity Commission, the National Labor
Relations Board, the Occupational Safety and Health Administration, the U.S. Securities and Exchange Commission, the Financial Industry Regulatory Authority, or any other self-regulatory organization or any other federal, state, or local
governmental agency or commission. The Service Provider acknowledges that the Service Provider is hereby notified, in accordance with the Defend Trade Secrets Act of 2016, 18 U.S.C. § 1833(b), that: (i) an individual shall not be held
criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, in each
case solely for the purpose of reporting or investigating a suspected violation of law; (ii) an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is
made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal; and (iii) an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose
the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (A) files any document containing the trade secret under seal and (B) does not disclose the trade secret
except pursuant to court order. 
 (d) Non-Disparagement. The Service Provider shall not at
any time, publicly or privately, verbally or in writing, directly or indirectly, make or cause to be made any defaming and/or disparaging, derogatory, misleading or false statement about Advent, Topco or its Subsidiaries, or their officers,
directors, employees, stockholders, members, partners or other Affiliates in any manner that would damage the business or reputation of Advent, Topco, the Subsidiaries or such Affiliates. 

  
 9 

 (e) Inventions. 

(i) The Service Provider acknowledges and agrees that all ideas, methods, inventions, discoveries, improvements, work products and
developments (“Inventions”), whether patentable or unpatentable, (x) that relate to the Service Provider’s work with the Company, made or conceived by the Service Provider, solely or jointly with others, during the
Employment Term, or (y) suggested by any work that the Service Provider performs in connection with the Company, either while performing the Service Provider’s duties with the Company or on the Service Provider’s own time, but only
insofar as the Inventions are related to the Service Provider’s work as an employee or other service provider to the Company, shall belong exclusively to the Company (or its designee), whether or not patent applications are filed thereon. The
Service Provider will keep full and complete written records (the “Records”), in the manner prescribed by the Company of all Inventions and will promptly disclose all Inventions completely and in writing to the Company. The Records
shall be the sole and exclusive property of the Company and the Service Provider will surrender them upon the termination of the Employment Term, or upon the Company’s request. The Service Provider will assign to the Company the Inventions and
all patents that may issue thereon in any and all countries, whether during or subsequent to the Employment Term, together with the right to file, in the Service Provider’s name or in the name of the Company (or its designee), applications for
patents and equivalent rights (the “Applications”). The Service Provider will, at any time during and subsequent to the Employment Term, make such applications, sign such papers, take all rightful oaths, and perform all acts as may
be requested from time to time by the Company with respect to the Inventions. The Service Provider will also execute assignments to the Company (or its designee), of the Applications, and give the Company and its attorneys all reasonable assistance
(including the giving of testimony) to obtain the Inventions for its benefit, all without additional compensation to the Service Provider from the Company but entirely at the Company’s expense. 

(ii) In addition, the Inventions will be deemed Work for Hire, as such term is defined under the copyright law of the United States, on
behalf of the Company and the Service Provider agrees that the Company will be the sole owner of the Inventions, and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity, without any
further obligations to the Service Provider. If the Inventions, or any portion thereof, are deemed not to be Work for Hire, the Service Provider hereby irrevocably conveys, transfers and assigns to the Company all rights, in all media now known or
hereinafter devised, throughout the universe and in perpetuity, in and to the Inventions, including, without limitation, all of the Service Provider’s right, title and interest in the copyrights (and all renewals, revivals and extensions
thereof) to the Inventions, including, without limitation, all rights of any kind or any nature now or hereafter recognized, including, without limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to
exploit and allow others to exploit the Inventions and all rights to sue at law or in equity for any infringement or other unauthorized use or conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without
limitation, the right to receive all proceeds and damages therefrom. In addition, the Service Provider hereby waives any so-called “moral rights” with respect to the Inventions. The Service Provider
hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including, without limitation, any rights that would otherwise accrue to the Service Provider’s benefit by

 5.2 Reformation. If it is determined by a court of competent jurisdiction in any state
or other jurisdiction that any restriction in this Section 5 is excessive in duration or scope or is unreasonable or unenforceable under the laws of that state or other jurisdiction, it is the intention of the parties that
such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the law of that state. 
 5.3
Enforcement; Remedies. The Service Provider acknowledges that the Service Provider’s expertise is of a special and unique character which gives this expertise a particular value, and that a breach of
Section 5.1 by the Service Provider will cause serious and potentially irreparable harm to the Company. The Service Provider therefore acknowledges that a breach of Section 5.1 by the Service
Provider cannot be adequately compensated in an action for damages at law, and equitable relief would be necessary to protect the Company from a violation of this Agreement and from the harm which this Agreement is intended to prevent. By reason
thereof, the Service Provider acknowledges that the Company is entitled, in addition to any other remedies it may have under this Agreement or otherwise, to preliminary and permanent injunctive and other equitable relief to prevent or curtail any
breach of this Agreement. The Service Provider acknowledges, however, that no specification in this Agreement of a specific legal or equitable remedy may be construed as a waiver of or prohibition against pursuing other legal or equitable remedies
in the event of a breach of this Agreement by the Service Provider. 
 5.4 Survival of Provisions. The obligations contained in
Section 5 shall survive the termination or expiration of the Service Provider’s Service and shall be fully enforceable thereafter.
