responsibilities and powers to any Person or Persons selected by it. Any such allocation or delegation may be revoked by the Committee at any time. Without limiting the generality of the foregoing, the Committee may delegate to one or more officers
of any member of the Company Group the authority to act on behalf of the Committee with respect to any matter, right, obligation, or election which is the responsibility of, or which is allocated to, the Committee herein, and which may be so

for an exemption provided by Rule 16b-3 promulgated under the Exchange Act related to Persons who are subject to Section 16 of the Exchange Act will be taken only by the Board or by a committee or
subcommittee of two or more Qualifying Directors. However, the fact that any member of such committee or subcommittee shall fail to qualify as a Qualifying Director shall not invalidate any action that is otherwise valid under the Plan. 

(d) Finality of Decisions. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other
decisions under or with respect to the Plan, any Award or any Award Agreement shall be within the sole discretion of the Committee, may be made at any time, and shall be final, conclusive, and binding upon all Persons, including, without limitation,

of any member of the Company Group (each such Person, an “Indemnifiable Person”) shall be liable for any action taken or omitted to be taken or any determination made with respect to the Plan or any Award hereunder (unless
constituting fraud or a willful criminal act or omission). Each Indemnifiable Person shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense (including attorneys’ fees) that may be imposed
upon or incurred by such Indemnifiable Person in connection with or resulting from any action, suit, or proceeding to which such Indemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any action taken
or omitted to be taken or determination made with respect to the Plan or any Award hereunder and against and from any and all amounts paid by such Indemnifiable Person with the Company’s approval, in settlement thereof, or paid by such
Indemnifiable Person in satisfaction of any judgment in any such action, suit, or proceeding against such Indemnifiable Person, and the Company shall advance to such Indemnifiable Person any such expenses promptly upon written request (which request
shall include an undertaking by the Indemnifiable Person to repay the amount of such advance if it shall ultimately be determined, as provided below, that the Indemnifiable Person is not entitled to be indemnified); provided, that the Company
shall have the right, at its own expense, to assume and defend any such action, suit, or proceeding and once the Company gives notice of its intent to assume the defense, the Company shall have sole control over such defense with counsel of the
Company’s choice. The foregoing right of indemnification shall not be available to an Indemnifiable Person to the extent that a final judgment or other final adjudication (in either case not subject to further appeal) binding upon such
Indemnifiable Person determines that the acts, omissions, or determinations of such Indemnifiable Person giving rise to the indemnification claim resulted from such Indemnifiable Person’s fraud or willful criminal act or omission or that such
right of indemnification is otherwise prohibited by law or by the organizational documents of any member of the Company Group. The foregoing right of indemnification shall not be exclusive of or otherwise supersede any other rights of
indemnification to which such Indemnifiable Persons may be entitled under the organizational documents of any member of the Company Group, as a matter of law, under an individual indemnification agreement or contract, or otherwise, or any other
power that the Company may have to indemnify such Indemnifiable Persons or hold such Indemnifiable Persons harmless. 
 (f) Board
Authority. Notwithstanding anything to the contrary contained in the Plan, the Board may, in its sole discretion, at any time and from time to time, grant Awards and administer the Plan with respect to such Awards. Any such actions by the Board
shall be subject to the applicable rules of the securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted. In any such case, the Board shall have all the authority granted to the Committee under the Plan.

 5. Grant of Awards; Shares Subject to the Plan; Limitations.  

(a) Grants. The Committee may, from time to time, grant Awards to one or more Eligible Persons. All Awards granted under the Plan shall

following limitations: (i) subject to Section 11 of the Plan, no more than [            ]1 shares of Common Stock (the
“Absolute Share Limit”) shall be available for Awards under the Plan; provided, however, that the Absolute Share Limit shall be automatically increased on the first day of each fiscal year following the fiscal
year in which the Effective Date falls in an amount equal to the lower of (x) 1% of the total number of shares of Common Stock outstanding on the last day of the immediately preceding fiscal year and (y) a lower number of shares of Common Stock
as determined by the Board; (ii) subject to Section 11 of the Plan, no more than the number of shares of Common Stock equal to the Absolute Share Limit may be issued in the aggregate pursuant to the exercise of Incentive Stock Options
granted under the Plan; and (iii) during a single fiscal year, each Non-Employee Director shall be granted a number of shares of Common Stock subject to Awards, taken together with any cash fees paid to
such Non-Employee Director during such fiscal year, equal to (A) a total value of $750,000 (calculating the value of any such Awards based on the grant date fair value of such Awards for financial
reporting purposes) or (B) such lower amount as determined by the Board prior to the Date of Grant, either as part of the Company’s Non-Employee Director compensation program or as otherwise
determined by the Board in the event of any change to such Non-Employee Director’s compensation program or for any particular period of service. To the extent the Board makes a determination pursuant to
clause (iii)(B) above with respect to any year of service, such determination shall in no event be applicable to any subsequent year of service without a further determination by the Board in respect of any subsequent year of service. 

(c) Share Counting. Other than with respect to Substitute Awards, to the extent that an Award expires or is canceled, forfeited,
terminated, settled in cash, or otherwise is settled without issuance to the Participant of the full number of shares of Common Stock to which the Award related, the unissued shares of Common Stock will again be available for grant under the Plan.
Shares of Common Stock withheld in payment of the Exercise Price, or taxes relating to an Award, and shares equal to the number of shares surrendered in payment of any Exercise Price, or taxes relating to an Award, shall be deemed to constitute
shares not issued to the Participant and shall be deemed to again be available for Awards under the Plan; provided, however, that such shares shall not become available for issuance hereunder if either: (i) the applicable shares are
withheld or surrendered following the termination of the Plan; or (ii) at the time the applicable shares are withheld or surrendered, it would constitute a material revision of the Plan subject to stockholder approval under any then-applicable
rules of the national securities exchange on which the Common Stock is listed. 
 (d) Source of Shares. Shares of Common Stock issued
by the Company in settlement of Awards may be authorized and unissued shares, shares of Common Stock held in the treasury of the Company, shares of Common Stock purchased on the open market or by private purchase, or a combination of the foregoing.

 (e) Substitute Awards. Awards may, in the sole discretion of the Committee, be
granted under the Plan in assumption of, or in substitution for, outstanding Awards previously granted by an entity directly or indirectly acquired by the Company or with which the Company combines (“Substitute Awards”).
Substitute Awards shall not be counted against the Absolute Share Limit; provided, that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding Options intended to qualify as “incentive stock
options” within the meaning of Section 422 of the Code shall be counted against the aggregate number of shares of Common Stock available for Awards of Incentive Stock Options under the Plan. Subject to applicable stock exchange
requirements, available shares of Common Stock under a stockholder-approved plan of an entity directly or indirectly acquired by the Company or with which the Company combines (as appropriately adjusted to reflect the acquisition or combination
transaction) may be used for Awards under the Plan and shall not reduce the number of shares of Common Stock available for issuance under the Plan. 

6. Eligibility. Participation in the Plan shall be limited to Eligible Persons. 

7. Options.  

(a) General. Each Option granted under the Plan shall be evidenced by an Award Agreement, which agreement need not be the same for each
Participant. Each Option so granted shall be subject to the conditions set forth in this Section 7, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options granted under the
Plan shall be Nonqualified Stock Options unless the applicable Award Agreement expressly states that the Option is intended to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees of a
member of the Company Group, and no Incentive Stock Option shall be granted to any Eligible Person who is ineligible to receive an Incentive Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has
been approved by the stockholders of the Company in a manner intended to comply with the stockholder approval requirements of Section 422(b)(1) of the Code; provided, that any Option intended to be an Incentive Stock Option shall not
fail to be effective solely on account of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified Stock Option unless and until such approval is obtained. In the case of an Incentive Stock Option, the terms and
conditions of such grant shall be subject to, and comply with, such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive Stock Option (or any portion thereof) shall not qualify as an
Incentive Stock Option, then, to the extent of such nonqualification, such Option or portion thereof shall be regarded as a Nonqualified Stock Option appropriately granted under the Plan. 

(b) Exercise Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise price
(“Exercise Price”) per share of Common Stock for each Option shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant); provided, however, that in the case of an Incentive
Stock Option granted to an employee who, at the time of the grant of such Option, owns stock representing more than 10% of the voting power of all classes of stock of any member of the Company Group, the Exercise Price per share shall be no less
than 110% of the Fair Market Value per share on the Date of Grant. 

  
 11 

 (c) Vesting and Expiration; Termination. 

(i) Options shall vest and become exercisable in such manner and on such date or dates or upon such event or events as
determined by the Committee including, without limitation, those set forth in Section 5(a) of the Plan; provided, however, that notwithstanding any such vesting dates or events, the Committee may in its sole discretion accelerate
the vesting of any Options at any time and for any reason. Options shall expire upon a date determined by the Committee, not to exceed ten years from the Date of Grant (the “Option Period”); provided, that if the
Option Period (other than in the case of an Incentive Stock Option) would expire at a time when trading in the shares of Common Stock is prohibited by the Company’s insider trading policy (or Company-imposed “blackout period”), then
the Option Period shall be automatically extended until the 30th day following the expiration of such prohibition. Notwithstanding the foregoing, in no event shall the Option Period exceed five
years from the Date of Grant in the case of an Incentive Stock Option granted to a Participant who on the Date of Grant owns stock representing more than 10% of the voting power of all classes of stock of any member of the Company Group. 

(ii) Unless otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of: (A) a
Participant’s Termination by the Service Recipient for Cause, all outstanding Options granted to such Participant shall immediately terminate and expire; (B) a Participant’s Termination due to death or Disability, each outstanding
unvested Option granted to such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain exercisable for one year thereafter (but in no event beyond the expiration of the Option Period); and (C) a
Participant’s Termination for any other reason, each outstanding unvested Option granted to such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain exercisable for 90 days thereafter (but in no
event beyond the expiration of the Option Period). 
 (d) Method of Exercise and Form of Payment. No shares of Common Stock shall be
issued pursuant to any exercise of an Option until payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal to any Federal, state, local, and
non-U.S. income, employment, and any other applicable taxes required to be withheld. Options which have become exercisable may be exercised by delivery of written or electronic notice of exercise to the
Company (or telephonic instructions to the extent provided by the Committee) in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall be payable: (i) in cash, check, cash equivalent,
and/or shares of Common Stock valued at the Fair Market Value at the time the Option is exercised (including, pursuant to procedures approved by the Committee, by means of attestation of ownership of a sufficient number of shares of Common Stock in
lieu of actual issuance of such shares to the Company); provided, that such shares of Common Stock are not subject to any pledge or other security interest and have been held by the Participant for at least six months (or such other period as
established from time to time by the Committee in order to avoid adverse accounting treatment applying generally accepted accounting principles (“GAAP”)); or (ii) by such other method as the Committee may permit in its
sole discretion, including, without limitation (A) in other property having a fair market value on the date of exercise equal to the Exercise Price; (B) if there is a public market for the shares of Common Stock at such time, by means of a
broker-assisted “cashless exercise” pursuant to which the 

  
 12 

 
Company is delivered (including telephonically to the extent permitted by the Committee) a copy of irrevocable instructions to a stockbroker to sell the shares of Common Stock otherwise issuable
upon the exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price; or (C) a “net exercise” procedure effected by withholding the minimum number of shares of Common Stock otherwise issuable in
respect of an Option that is needed to pay the Exercise Price. Any fractional shares of Common Stock shall be settled in cash. 
 (e)
Notification upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded an Incentive Stock Option under the Plan shall notify the Company in writing immediately after the date the Participant makes a disqualifying
disposition of any share of Common Stock acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition is any disposition (including, without limitation, any sale) of such share of Common Stock before the later of
(i) the date that is two years after the Date of Grant of the Incentive Stock Option, or (ii) the date that is one year after the date of exercise of the Incentive Stock Option. The Company may, if determined by the Committee and in
accordance with procedures established by the Committee, retain possession, as agent for the applicable Participant, of any share of Common Stock acquired pursuant to the exercise of an Incentive Stock Option until the end of the period described in
the preceding sentence, subject to complying with any instructions from such Participant as to the sale of such share of Common Stock. 
 (f)
Compliance With Laws, etc. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner which the Committee determines would violate the Sarbanes-Oxley Act of 2002, as it may be amended from
time to time, or any other applicable law or the applicable rules and regulations of the Securities and Exchange Commission or the applicable rules and regulations of any securities exchange or inter-dealer quotation system on which the securities
of the Company are listed or traded. 
 8. Stock Appreciation Rights.  

(a) General. Each SAR granted under the Plan shall be evidenced by an Award Agreement. Each SAR so granted shall be subject to the
conditions set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. Any Option granted under the Plan may include tandem SARs. The Committee also may award
SARs to Eligible Persons independent of any Option. 
 (b) Strike Price. Except as otherwise provided by the Committee in the case of
Substitute Awards, the strike price (“Strike Price”) per share of Common Stock for each SAR shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant). Notwithstanding the
foregoing, a SAR granted in tandem with (or in substitution for) an Option previously granted shall have a Strike Price equal to the Exercise Price of the corresponding Option. 

  
 13 

 (c) Vesting and Expiration; Termination. 

(i) A SAR granted in connection with an Option shall become exercisable and shall expire according to the same vesting schedule
and expiration provisions as the corresponding Option. A SAR granted independent of an Option shall vest and become exercisable in such manner and on such date or dates or upon such event or events as determined by the Committee including, without
limitation, those set forth in Section 5(a) of the Plan; provided, however, that notwithstanding any such vesting dates or events, the Committee may, in its sole discretion, accelerate the vesting of any SAR at any time and for
any reason. SARs shall expire upon a date determined by the Committee, not to exceed ten years from the Date of Grant (the “SAR Period”); provided, that if the SAR Period would expire at a time when trading in the
shares of Common Stock is prohibited by the Company’s insider trading policy (or Company-imposed “blackout period”), then the SAR Period shall be automatically extended until the 30th day following the expiration of such prohibition. 
 (ii) Unless otherwise
provided by the Committee, whether in an Award Agreement or otherwise, in the event of: (A) a Participant’s Termination by the Service Recipient for Cause, all outstanding SARs granted to such Participant shall immediately terminate and
expire; (B) a Participant’s Termination due to death or Disability, each outstanding unvested SAR granted to such Participant shall immediately terminate and expire, and each outstanding vested SAR shall remain exercisable for one year
thereafter (but in no event beyond the expiration of the SAR Period); and (C) a Participant’s Termination for any other reason, each outstanding unvested SAR granted to such Participant shall immediately terminate and expire, and each
outstanding vested SAR shall remain exercisable for 90 days thereafter (but in no event beyond the expiration of the SAR Period). 
 (d)
Method of Exercise. SARs which have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company in accordance with the terms of the Award, specifying the number of SARs to be exercised and the
date on which such SARs were awarded. 
 (e) Payment. Upon the exercise of a SAR, the Company shall pay to the Participant an amount
equal to the number of shares subject to the SAR that is being exercised multiplied by the excess of the Fair Market Value of one share of Common Stock on the exercise date over the Strike Price, less an amount equal to any Federal, state, local,
and non-U.S. income, employment, and any other applicable taxes required to be withheld. The Company shall pay such amount in cash, in shares of Common Stock valued at Fair Market Value, or any combination
thereof, as determined by the Committee. Any fractional shares of Common Stock shall be settled in cash. 
 9. Restricted Stock and
Restricted Stock Units.  
 (a) General. Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an
Award Agreement. Each Restricted Stock and Restricted Stock Unit so granted shall be subject to the conditions set forth in this Section 9, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award
Agreement. 

  
 14 

 (b) Stock Certificates and Book-Entry Notation; Escrow or Similar Arrangement. Upon
the grant of Restricted Stock, the Committee shall cause a stock certificate registered in the name of the Participant to be issued or shall cause share(s) of Common Stock to be registered in the name of the Participant and held in book-entry form
subject to the Company’s directions and, if the Committee determines that the Restricted Stock shall be held by the Company or in escrow rather than issued to the Participant pending the release of the applicable restrictions, the Committee may
require the Participant to additionally execute and deliver to the Company (i) an escrow agreement satisfactory to the Committee, if applicable, and (ii) the appropriate stock power (endorsed in blank) with respect to the Restricted Stock
covered by such agreement. If a Participant shall fail to execute and deliver (in a manner permitted under Section 13(a) of the Plan or as otherwise determined by the Committee) an agreement evidencing an Award of Restricted Stock and, if
applicable, an escrow agreement and blank stock power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Section 9 and the applicable Award Agreement, a
Participant generally shall have the rights and privileges of a stockholder as to shares of Restricted Stock, including, without limitation, the right to vote such Restricted Stock and receive dividends in respect of such Restricted Stock, subject
to the limitations set forth in Section 13(c)(ii). To the extent shares of Restricted Stock are forfeited, any stock certificates issued to the Participant evidencing such shares shall be returned to the Company, and all rights of the
Participant to such shares and as a stockholder with respect thereto shall terminate without further obligation on the part of the Company. A Participant shall have no rights or privileges as a stockholder as to Restricted Stock Units. 

(c) Vesting; Termination. 

(i) Restricted Stock and Restricted Stock Units shall vest, and any applicable Restricted Period shall lapse, in such manner
and on such date or dates or upon such event or events as determined by the Committee including, without limitation, those set forth in Section 5(a) of the Plan; provided, however, that notwithstanding any such dates or events,
the Committee may, in its sole discretion, accelerate the vesting of any Restricted Stock or Restricted Stock Unit or the lapsing of any applicable Restricted Period at any time and for any reason. 

(ii) Unless otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of a
Participant’s Termination for any reason prior to the time that such Participant’s Restricted Stock or Restricted Stock Units, as applicable, have vested, (A) all vesting with respect to such Participant’s Restricted Stock or
Restricted Stock Units, as applicable, shall cease and (B) unvested shares of Restricted Stock and unvested Restricted Stock Units, as applicable, shall be forfeited to the Company by the Participant for no consideration as of the date of such
Termination. 
 (d) Issuance of Restricted Stock and Settlement of Restricted Stock Units. 

(i) Upon the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set forth in
the applicable Award Agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award Agreement. If an escrow arrangement is used, upon such expiration the Company shall issue to the
Participant or the Participant’s beneficiary, without charge, the stock certificate (or, if applicable, a notice evidencing a book-entry notation) evidencing the shares of Restricted Stock which have not then been forfeited and with respect to
which the Restricted Period has expired (rounded down to the nearest full share). 

  
 15 

 (ii) Unless otherwise provided by the Committee in an Award Agreement or
otherwise, upon the expiration of the Restricted Period with respect to any outstanding Restricted Stock Units, the Company shall issue to the Participant or the Participant’s beneficiary, without charge, one share of Common Stock (or other
securities or other property, as applicable) for each such outstanding Restricted Stock Unit; provided, however, that the Committee may, in its sole discretion, elect to (A) pay cash or part cash and part shares of Common Stock in lieu
of issuing only shares of Common Stock in respect of such Restricted Stock Units or (B) defer the issuance of shares of Common Stock (or cash or part cash and part shares of Common Stock, as the case may be) beyond the expiration of the
Restricted Period if such extension would not cause adverse tax consequences under Section 409A of the Code. If a cash payment is made in lieu of issuing shares of Common Stock in respect of such Restricted Stock Units, the amount of such
payment shall be equal to the Fair Market Value per share of the Common Stock as of the date on which the Restricted Period lapsed with respect to such Restricted Stock Units. 

(e) Legends on Restricted Stock. Each certificate, if any, or book entry representing Restricted Stock awarded under the Plan, if any,
shall bear a legend or book entry notation substantially in the form of the following, in addition to any other information the Company deems appropriate, until the lapse of all restrictions with respect to such shares of Common Stock: 

TRANSFER OF THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE AVANTOR, INC. 2019 EQUITY INCENTIVE
PLAN AND A RESTRICTED STOCK AWARD AGREEMENT BETWEEN AVANTOR, INC. AND THE PARTICIPANT. A COPY OF SUCH PLAN AND AWARD AGREEMENT IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF AVANTOR, INC. 

10. Other Equity-Based Awards and Other Cash-Based Awards. The Committee may grant Other Equity-Based Awards and Other Cash-Based
Awards under the Plan to Eligible Persons, alone or in tandem with other Awards, in such amounts and dependent on such conditions as the Committee shall from time to time in its sole discretion determine including, without limitation, those set
forth in Section 5(a) of the Plan. Each Other Equity-Based Award granted under the Plan shall be evidenced by an Award Agreement and each Other Cash-Based Award granted under the Plan shall be evidenced in such form as the Committee may
determine from time to time. Each Other Equity-Based Award or Other Cash-Based Award, as applicable, so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement or other form
evidencing such Award, including, without limitation, those set forth in Section 13(c) of the Plan. 
 11. Changes in Capital
Structure and Similar Events. Notwithstanding any other provision in this Plan to the contrary, the following provisions shall apply to all Awards granted hereunder (other than Other Cash-Based Awards): 

  
 16 

 (a) General. In the event of (i) any dividend (other than regular cash
dividends) or other distribution (whether in the form of cash, shares of Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation,
split-up, split-off, spin-off, combination, repurchase, or exchange of shares of Common Stock or other securities of the Company,
issuance of warrants or other rights to acquire shares of Common Stock or other securities of the Company, or other similar corporate transaction or event that affects the shares of Common Stock (including a Change in Control), or (ii) unusual
or nonrecurring events affecting the Company, including changes in applicable rules, rulings, regulations, or other requirements, that the Committee determines, in its sole discretion, could result in substantial dilution or enlargement of the
rights intended to be granted to, or available for, Participants (any event in (i) or (ii), an “Adjustment Event”), the Committee shall, in respect of any such Adjustment Event, make such proportionate substitution or
adjustment, if any, as it deems equitable, to any or all of: (A) the Absolute Share Limit, or any other limit applicable under the Plan with respect to the number of Awards which may be granted hereunder; (B) the number of shares of Common
Stock or other securities of the Company (or number and kind of other securities or other property) which may be issued in respect of Awards or with respect to which Awards may be granted under the Plan; and (C) the terms of any outstanding
Award, including, without limitation, (I) the number of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding Awards relate;
(II) the Exercise Price or Strike Price with respect to any Award; or (III) any applicable performance measures; provided, that in the case of any “equity restructuring” (within the meaning of the Financial Accounting
Standards Board Accounting Standards Codification Topic 718 (or any successor pronouncement thereto)), the Committee shall make an equitable or proportionate adjustment to outstanding Awards to reflect such equity restructuring. Any adjustment under
this Section 11 shall be conclusive and binding for all purposes. 
 (b) Adjustment Events. Without limiting the foregoing,
except as may otherwise be provided in an Award Agreement, in connection with any Adjustment Event, the Committee may, in its sole discretion, provide for any one or more of the following: 

(i) substitution or assumption of Awards (or awards of an acquiring company), acceleration of the exercisability of, lapse of
restrictions on, or termination of Awards, or a period of time (which shall not be required to be more than ten days) for Participants to exercise outstanding Awards prior to the occurrence of such event (and any such Award not so exercised shall
terminate upon the occurrence of such event); and 
 (ii) subject to any limitations or reductions as may be necessary to
comply with Section 409A of the Code, cancellation of any one or more outstanding Awards and payment to the holders of such Awards that are vested as of such cancellation (including, without limitation, any Awards that would vest as a result of
the occurrence of such event but for such cancellation or for which vesting is accelerated by the Committee in connection with such event) the value of such Awards, if any, as determined by the Committee (which value, if applicable, may be based
upon the price per share of Common Stock received or to be received by other stockholders of the Company in such 

  
 17 

 
event), including, without limitation, in the case of an outstanding Option or SAR, a cash payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by
the Committee) of the shares of Common Stock subject to such Option or SAR over the aggregate Exercise Price or Strike Price of such Option or SAR (it being understood that, in such event, any Option or SAR having a per share Exercise Price or
Strike Price equal to, or in excess of, the Fair Market Value of a share of Common Stock subject thereto may be canceled and terminated without any payment or consideration therefor), or, in the case of Restricted Stock, Restricted Stock Units, or
Other Equity-Based Awards that are not vested as of such cancellation, a cash payment or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted
Stock, Restricted Stock Units, or Other Equity-Based Awards prior to cancellation, or the underlying shares in respect thereof. 
 Payments to holders
pursuant to clause (ii) above shall be made in cash or, in the sole discretion of the Committee, in the form of such other consideration necessary for a Participant to receive property, cash, or securities (or combination thereof) as such
Participant would have been entitled to receive upon the occurrence of the transaction if the Participant had been, immediately prior to such transaction, the holder of the number of shares of Common Stock covered by the Award at such time (less any
applicable Exercise Price or Strike Price). 
 (c) Other Requirements. Prior to any payment or adjustment contemplated under this
Section 11, the Committee may require a Participant to (i) represent and warrant as to the unencumbered title to the Participant’s Awards; (ii) bear such Participant’s pro rata share of any post-closing indemnity
obligations, and be subject to the same post-closing purchase price adjustments, escrow terms, offset rights, holdback terms, and similar conditions as the other holders of Common Stock, subject to any limitations or reductions as may be necessary
to comply with Section 409A of the Code; and (iii) deliver customary transfer documentation as reasonably determined by the Committee. 

(d) Fractional Shares. Any adjustment provided under this Section 11 may provide for the elimination of any fractional share
that might otherwise become subject to an Award. 
 (e) Binding Effect. Any adjustment, substitution, determination of value or other
action taken by the Committee under this Section 11 shall be conclusive and binding for all purposes. 
 12. Amendments and
Termination.  
 (a) Amendment and Termination of the Plan. The Board may amend, alter, suspend, discontinue, or terminate
the Plan or any portion thereof at any time; provided, that no such amendment, alteration, suspension, discontinuance, or termination shall be made without stockholder approval if: (i) such approval is necessary to comply with any
regulatory requirement applicable to the Plan (including, without limitation, as necessary to comply with any rules or regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company may be listed or
quoted) or for changes in GAAP to new accounting standards; (ii) it would materially increase the number of securities which may be issued under the Plan (except for increases pursuant to Section 5 or 11 of the Plan), or (iii) it

  
 18 

 
would materially modify the requirements for participation in the Plan; provided, further, that any such amendment, alteration, suspension, discontinuance, or termination that would
materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant, holder, or beneficiary.
Notwithstanding the foregoing, no amendment shall be made to the last proviso of Section 12(b) of the Plan without stockholder approval. 

(b) Amendment of Award Agreements. The Committee may, to the extent consistent with the terms of the Plan and any applicable Award
Agreement, waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel, or terminate, any Award theretofore granted or the associated Award Agreement, prospectively or retroactively (including after a
Participant’s Termination); provided, that, other than pursuant to Section 11, any such waiver, amendment, alteration, suspension, discontinuance, cancellation, or termination that would materially and adversely affect the rights of
any Participant with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant; provided, further, that without stockholder approval, except as otherwise permitted under
Section 11 of the Plan, (i) no amendment or modification may reduce the Exercise Price of any Option or the Strike Price of any SAR; (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or
SAR (with a lower Exercise Price or Strike Price, as the case may be) or other Award or cash payment that is greater than the intrinsic value (if any) of the canceled Option or SAR; and (iii) the Committee may not take any other action which is
considered a “repricing” for purposes of the stockholder approval rules of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted. 

13. General. 
 (a) Award
Agreements. Each Award (other than an Other Cash-Based Award) under the Plan shall be evidenced by an Award Agreement, which shall be delivered to the Participant to whom such Award was granted and shall specify the terms and conditions of the
Award and any rules applicable thereto, including, without limitation, the effect on such Award of the death, Disability, or Termination of a Participant, or of such other events as may be determined by the Committee. For purposes of the Plan, an
Award Agreement may be in any such form (written or electronic) as determined by the Committee (including, without limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate, or a letter) evidencing the Award. The
Committee need not require an Award Agreement to be signed by the Participant or a duly authorized representative of the Company. 
 (b)
Nontransferability. 
 (i) Each Award shall be exercisable only by such Participant to whom such Award was granted
during the Participant’s lifetime, or, if permissible under applicable law, by the Participant’s legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold, or otherwise transferred or encumbered by a
Participant (unless such transfer is specifically required pursuant to a domestic relations order or by applicable law) other than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment,
sale, transfer, or encumbrance shall be void and unenforceable against any member of the Company Group; provided, that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer, or
encumbrance. 

  
 19 

 (ii) Notwithstanding the foregoing, the Committee may, in its sole
discretion, permit Awards (other than Incentive Stock Options) to be transferred by a Participant, without consideration, subject to such rules as the Committee may adopt consistent with any applicable Award Agreement to preserve the purposes of the
Plan, to: (A) any Person who is a “family member” of the Participant, as such term is used in the instructions to Form S-8 under the Securities Act or any successor form of registration
statement promulgated by the Securities and Exchange Commission (collectively, the “Immediate Family Members”); (B) a trust solely for the benefit of the Participant and the Participant’s Immediate Family Members;
(C) a partnership or limited liability company whose only partners or stockholders are the Participant and the Participant’s Immediate Family Members; or (D) a beneficiary to whom donations are eligible to be treated as
“charitable contributions” for federal income tax purposes (each transferee described in clauses (A), (B), (C), and (D) above is hereinafter referred to as a “Permitted Transferee”); provided, that the
Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan. 

(iii) The terms of any Award transferred in accordance with clause (ii) above shall apply to the Permitted Transferee and
any reference in the Plan or in any applicable Award Agreement to a Participant shall be deemed to refer to the Permitted Transferee, except that: (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the
laws of descent and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in effect a registration statement on an appropriate form covering the shares of Common Stock to be
acquired pursuant to the exercise of such Option if the Committee determines, consistent with any applicable Award Agreement, that such a registration statement is necessary or appropriate; (C) neither the Committee nor the Company shall be
required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of a Participant’s
Termination under the terms of the Plan and the applicable Award Agreement shall continue to be applied with respect to the Participant, including, without limitation, that an Option shall be exercisable by the Permitted Transferee only to the
extent, and for the periods, specified in the Plan and the applicable Award Agreement. 
 (c) Dividends and Dividend Equivalents. 

(i) The Committee may, in its sole discretion, provide a Participant as part of an Award with dividends, dividend equivalents,
or similar payments in respect of Awards, payable in cash, shares of Common Stock, other securities, other Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee in its sole
discretion, including, without limitation, payment directly to the Participant, withholding of such amounts by the Company subject to vesting of the Award or reinvestment in additional shares of Common Stock, Restricted Stock or other Awards. 

  
 20 

 (ii) Without limiting the foregoing, unless otherwise provided in the Award
Agreement, any dividend otherwise payable in respect of any share of Restricted Stock that remains subject to vesting conditions at the time of payment of such dividend shall be retained by the Company, remain subject to the same vesting conditions
as the share of Restricted Stock to which the dividend relates and shall be delivered (without interest) to the Participant within 15 days following the date on which such restrictions on such Restricted Stock lapse (and the right to any such
accumulated dividends shall be forfeited upon the forfeiture of the Restricted Stock to which such dividends relate). 

(iii) To the extent provided in an Award Agreement, the holder of outstanding Restricted Stock Units shall be entitled to be
credited with dividend equivalent payments (upon the payment by the Company of dividends on shares of Common Stock) either in cash or, in the sole discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount
of such dividends (and interest may, in the sole discretion of the Committee, be credited on the amount of cash dividend equivalents at a rate and subject to such terms as determined by the Committee), which accumulated dividend equivalents (and
interest thereon, if applicable) shall be payable at the same time as the underlying Restricted Stock Units are settled following the date on which the Restricted Period lapses with respect to such Restricted Stock Units, and if such Restricted
Stock Units are forfeited, the Participant shall have no right to such dividend equivalent payments (or interest thereon, if applicable). 

(d) Tax Withholding. 

(i) A Participant shall be required to pay to the Company or one or more of its Subsidiaries, as applicable, an amount in cash
(by check or wire transfer) equal to the aggregate amount of any income, employment, and/or other applicable taxes that are statutorily required to be withheld in respect of an Award. Alternatively, the Company or any of its Subsidiaries may elect,
in its sole discretion, to satisfy this requirement by withholding such amount from any cash compensation or other cash amounts owing to a Participant. 

(ii) Without limiting the foregoing, the Committee may (but is not obligated to), in its sole discretion, permit or require a
Participant to satisfy all or any portion of the minimum income, employment, and/or other applicable taxes that are statutorily required to be withheld with respect to an Award by: (A) the delivery of shares of Common Stock (which are not
subject to any pledge or other security interest) that have been both held by the Participant and vested for at least six months (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment
under applicable accounting standards) having an aggregate Fair Market Value equal to such minimum statutorily required withholding liability (or portion thereof); or (B) having the Company withhold from the shares of Common Stock otherwise
issuable or deliverable to, or that would otherwise be retained by, the Participant upon the grant, exercise, vesting, or settlement of the Award, as applicable, a number of shares of Common Stock with an aggregate Fair Market Value equal to an
amount, subject to clause (iii) below, not in excess of such minimum statutorily required withholding liability (or portion thereof). 

  
 21 

 (iii) The Committee, subject to its having considered the applicable
accounting impact of any such determination, has full discretion to allow Participants to satisfy, in whole or in part, any additional income, employment, and/or other applicable taxes payable by them with respect to an Award by electing to have the
Company withhold from the shares of Common Stock otherwise issuable or deliverable to, or that would otherwise be retained by, a Participant upon the grant, exercise, vesting, or settlement of the Award, as applicable, shares of Common Stock having
an aggregate Fair Market Value that is greater than the applicable minimum required statutory withholding liability (but such withholding may in no event be in excess of the maximum statutory withholding amount(s) in a Participant’s relevant
tax jurisdictions). 
 (e) Data Protection. By participating in the Plan or accepting any rights granted under it, each Participant
consents to the collection and processing of personal data relating to the Participant so that the Company and its Affiliates can fulfill their obligations and exercise their rights under the Plan and generally administer and manage the Plan. This
data will include, but may not be limited to, data about participation in the Plan and shares offered or received, purchased, or sold under the Plan from time to time and other appropriate financial and other data (such as the date on which the
Awards were granted) about the Participant and the Participant’s participation in the Plan. 
 (f) No Claim to Awards; No Rights to
Continued Employment; Waiver. No employee of any member of the Company Group, or other Person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of
any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not
be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any
right to be retained in the employ or service of the Service Recipient or any other member of the Company Group, nor shall it be construed as giving any Participant any rights to continued service on the Board. The Service Recipient or any other
member of the Company Group may at any time dismiss a Participant from employment or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or any Award
Agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to
non-continuation of the Award beyond the period provided under the Plan or any Award Agreement, except to the extent of any provision to the contrary in any written employment contract or other agreement
between the Service Recipient and/or any member of the Company Group and the Participant, whether any such agreement is executed before, on, or after the Date of Grant. 

  
 22 

 (g) Designation and Change of Beneficiary. Each Participant may file with the
Committee a written designation of one or more Persons as the beneficiary or beneficiaries, as applicable, who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon the Participant’s death. A
Participant may, from time to time, revoke or change the Participant’s beneficiary designation without the consent of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee
shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant’s death, and in no event shall it be effective as of a date prior
to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be the Participant’s spouse or, if the Participant is unmarried at the time of death, the Participant’s estate. 

(h) Termination. Except as otherwise provided in an Award Agreement, unless determined otherwise by the Committee at any point following
such event: (i) neither a temporary absence from employment or service due to illness, vacation, or leave of absence (including, without limitation, a call to active duty for military service through a Reserve or National Guard unit) nor a
transfer from employment or service with one Service Recipient to employment or service with another Service Recipient (or vice-versa) shall be considered a Termination; and (ii) if a Participant undergoes a Termination, but such Participant
continues to provide services to the Company Group in a non-employee capacity, such change in status shall not be considered a Termination for purposes of the Plan. Further, unless otherwise determined by the
Committee, in the event that any Service Recipient ceases to be a member of the Company Group (by reason of sale, divestiture, spin-off, or other similar transaction), unless a Participant’s employment or
service is transferred to another entity that would constitute a Service Recipient immediately following such transaction, such Participant shall be deemed to have suffered a Termination hereunder as of the date of the consummation of such
transaction. 
 (i) No Rights as a Stockholder. Except as otherwise specifically provided in the Plan or any Award Agreement, no
Person shall be entitled to the privileges of ownership in respect of shares of Common Stock which are subject to Awards hereunder until such shares have been issued or delivered to such Person. 

(j) Government and Other Regulations. 

(i) The obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject to all
applicable laws, rules, and regulations, and to such approvals by governmental agencies as may be required. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell,
and shall be prohibited from offering to sell or selling, any shares of Common Stock pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless
the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms
and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Committee shall have
the authority to provide that all shares of Common Stock or other securities of 

  
 23 

 
any member of the Company Group issued under the Plan shall be subject to such stop-transfer orders and other restrictions as the Committee may deem
advisable under the Plan, the applicable Award Agreement, the Federal securities laws, or the rules, regulations, and other requirements of the Securities and Exchange Commission and any securities exchange or inter-dealer quotation system on which
the securities of the Company are listed or quoted, and any other applicable Federal, state, local, or non-U.S. laws, rules, regulations, and other requirements, and, without limiting the generality of
Section 9 of the Plan, the Committee may cause a legend or legends to be put on certificates representing shares of Common Stock or other securities of any member of the Company Group issued under the Plan to make appropriate reference to such
restrictions or may cause such Common Stock or other securities of any member of the Company Group issued under the Plan in book-entry form to be held subject to the Company’s instructions or subject to appropriate stop-transfer orders.
Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add, at any time, any additional terms or provisions to any Award granted under the Plan that the Committee, in its sole discretion, deems necessary or
advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject. 

(ii) The Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or
contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of shares of Common Stock from the public markets, the Company’s issuance of Common Stock to the Participant, the
Participant’s acquisition of Common Stock from the Company, and/or the Participant’s sale of Common Stock to the public markets, illegal, impracticable, or inadvisable. If the Committee determines to cancel all or any portion of an Award
in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to comply with Section 409A of the Code: (A) pay to the Participant an amount equal to the excess of (I) the aggregate
Fair Market Value of the shares of Common Stock subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested or issued, as applicable), over (II) the
aggregate Exercise Price or Strike Price (in the case of an Option or SAR, respectively) or any amount payable as a condition of issuance of shares of Common Stock (in the case of any other Award), with such amount being delivered to the Participant
as soon as practicable following the cancellation of such Award or portion thereof or (B) in the case of Restricted Stock, Restricted Stock Units, or Other Equity-Based Awards, provide the Participant with a cash payment or equity subject to
deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted Stock, Restricted Stock Units, or Other Equity-Based Awards, or the underlying shares in respect thereof. 

(k) Section 83(b) Elections. If a Participant, in connection with the acquisition of shares of Common Stock under the
Plan or otherwise, makes an election under Section 83(b) of the Code or a similar provision of law, the Participant shall notify the Company of such election within ten days of filing notice of the election with the Internal Revenue Service or
other governmental authority, in addition to any filing and notification required pursuant to Section 83(b) of the Code or other applicable provision. 

  
 24 

 (l) Payments to Persons Other Than Participants. If the Committee shall find that any
Person to whom any amount is payable under the Plan is unable to care for the Participant’s affairs because of illness or accident, or is a minor, or has died, then any payment due to such Person or the Participant’s estate (unless a prior
claim therefor has been made by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to the Participant’s spouse, child, relative, an institution maintaining or having custody of such Person, or any other
Person deemed by the Committee to be a proper recipient on behalf of such Person otherwise entitled to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor. 

(m) Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board nor the submission of the Plan to the stockholders of the
Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of
equity-based awards otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases. 

(n) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind
or a fiduciary relationship between any member of the Company Group, on the one hand, and a Participant or other Person, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of satisfying any
obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or otherwise to segregate any assets, nor shall the Company be obligated to maintain separate bank accounts, books,
records, or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no rights under the Plan other than as unsecured general creditors of the Company, except that
insofar as they may have become entitled to payment of additional compensation by performance of services, they shall have the same rights as other service providers under general law. 

(o) Reliance on Reports. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act,
as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of any member of the Company Group and/or any other information furnished in
connection with the Plan by any agent of the Company or the Committee or the Board, other than himself or herself. 
 (p) Relationship to
Other Benefits. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, profit sharing, group insurance, or other benefit plan of the Company except as otherwise specifically provided in
such other plan or as required by applicable law. 
 (q) Governing Law. The Plan shall be governed by and construed in accordance with
the internal laws of the State of Delaware applicable to contracts made and performed wholly within the State of Delaware, without giving effect to the conflict of laws’ provisions thereof. EACH PARTICIPANT WHO ACCEPTS AN AWARD IRREVOCABLY
WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY SUIT, ACTION, OR OTHER PROCEEDING INSTITUTED BY OR AGAINST SUCH PARTICIPANT IN RESPECT OF THE PARTICIPANT’S RIGHTS OR OBLIGATIONS HEREUNDER. 

  
 25 

 (r) Severability. If any provision of the Plan or any Award or Award Agreement is or
becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed
amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken
as to such jurisdiction, Person, or Award and the remainder of the Plan and any such Award shall remain in full force and effect. 
 (s)
Obligations Binding on Successors. The obligations of the Company under the Plan shall be binding upon any successor corporation or organization resulting from the merger, consolidation, or other reorganization of the Company, or upon any
successor corporation or organization succeeding to substantially all of the assets and business of the Company. 
 (t)
Section 409A of the Code. 
 (i) Notwithstanding any provision of the Plan to the contrary, it is
intended that the provisions of the Plan comply with Section 409A of the Code, and all provisions of the Plan shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under
Section 409A of the Code. Each Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or in respect of such Participant in connection with the Plan (including any taxes and penalties
under Section 409A of the Code), and neither the Service Recipient nor any other member of the Company Group shall have any obligation to indemnify or otherwise hold such Participant (or any beneficiary) harmless from any or all of such taxes
or penalties. With respect to any Award that is considered “deferred compensation” subject to Section 409A of the Code, references in the Plan to “termination of employment” (and substantially similar phrases) shall mean
“separation from service” within the meaning of Section 409A of the Code. For purposes of Section 409A of the Code, each of the payments that may be made in respect of any Award granted under the Plan is designated as a separate
payment. 
 (ii) Notwithstanding anything in the Plan to the contrary, if a Participant is a “specified employee”
within the meaning of Section 409A(a)(2)(B)(i) of the Code, no payments in respect of any Awards that are “deferred compensation” subject to Section 409A of the Code and which would otherwise be payable upon the
Participant’s “separation from service” (as defined in Section 409A of the Code) shall be made to such Participant prior to the date that is six months after the date of such Participant’s “separation from service”
or, if earlier, the date of the Participant’s death. Following any applicable six-month delay, all such delayed payments will be paid in a single lump sum on the earliest date permitted under
Section 409A of the Code that is also a business day. 

  
 26 

 (iii) Unless otherwise provided by the Committee in an Award Agreement or
otherwise, in the event that the timing of payments in respect of any Award (that would otherwise be considered “deferred compensation” subject to Section 409A of the Code) are accelerated upon the occurrence of (A) a Change in
Control, no such acceleration shall be permitted unless the event giving rise to the Change in Control satisfies the definition of a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion
of the assets of a corporation pursuant to Section 409A of the Code or (B) a Disability, no such acceleration shall be permitted unless the Disability also satisfies the definition of “Disability” pursuant to Section 409A of
the Code. 
 (u) Clawback/Repayment. All Awards shall be subject to reduction, cancellation, forfeiture or recoupment to the extent
necessary to comply with (i) any clawback, forfeiture or other similar policy adopted by the Board or the Committee and as in effect from time to time; and (ii) applicable law. Further, unless otherwise determined by the Committee, to the
extent that the Participant receives any amount in excess of the amount that the Participant should otherwise have received under the terms of the Award for any reason (including, without limitation, by reason of a financial restatement, mistake in
calculations or other administrative error), the Participant shall be required to repay any such excess amount to the Company. 
 (v)
Detrimental Activity. Notwithstanding anything to the contrary contained herein, if a Participant has engaged in any Detrimental Activity, as determined by the Committee, the Committee may, in its sole discretion, provide for one or more of
the following: 
 (i) cancellation of any or all of such Participant’s outstanding Awards; or 

(ii) forfeiture by the Participant of any gain realized on the vesting or exercise of Awards, and repayment of any such gain
promptly to the Company. 
 (w) Right of Offset. The Company will have the right to offset against its obligation to deliver shares of
Common Stock (or other property or cash) under the Plan or any Award Agreement any outstanding amounts (including, without limitation, travel and entertainment or advance account balances, loans, repayment obligations under any Awards, or amounts
repayable to the Company pursuant to tax equalization, housing, automobile, or other employee programs) that the Participant then owes to any member of the Company Group and any amounts the Committee otherwise deems appropriate pursuant to any tax
equalization policy or agreement. Notwithstanding the foregoing, if an Award is “deferred compensation” subject to Section 409A of the Code, the Committee will have no right to offset against its obligation to deliver shares of Common
Stock (or other property or cash) under the Plan or any Award Agreement if such offset could subject the Participant to the additional tax imposed under Section 409A of the Code in respect of an outstanding Award. 

(x) Expenses; Titles and Headings. The expenses of administering the Plan shall be borne by the Company Group. The titles and headings
of the sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

UNDER THE 
 AVANTOR, INC.

 2019 EQUITY INCENTIVE PLAN 

Pursuant to the Option Grant Notice (the “Grant Notice”) delivered to the Participant (as defined in the Grant
Notice), and subject to the terms of this Option Agreement (this “Option Agreement”) and the Avantor, Inc. 2019 Equity Incentive Plan, as it may be amended and restated from time to time (the
“Plan”), Avantor, Inc. (the “Company”) and the Participant agree as follows. Capitalized terms not otherwise defined herein shall have the same meaning as set forth in the Plan. 

1. Grant of Option. Subject to the terms and conditions set forth herein and in the Plan, the Company hereby grants to the
Participant the number of Options provided in the Grant Notice (with each Option representing the right to purchase one share of Common Stock), at an Exercise Price per share as provided in the Grant Notice. The Company may make one or more
additional grants of Options to the Participant under this Option Agreement by providing the Participant with a new Grant Notice, which may also include any terms and conditions differing from this Option Agreement to the extent provided therein.
The Company reserves all rights with respect to the granting of additional Options hereunder and makes no implied promise to grant additional Options. 

2. Vesting. 
 (a)
Subject to the conditions contained herein and in the Plan, the Options shall vest as provided in the Grant Notice. 
 (b) In the event of a
Change in Control, provided that the Participant has not undergone a Termination prior to occurrence thereof, any unvested Options will become vested as of immediately prior to such Change in Control. 

3. Exercise of Options Following Termination. The provisions of Section 7(c)(ii) of the Plan are incorporated herein by
reference and made a part hereof. 
 4. Method of Exercising Options. The Options may be exercised by the delivery of notice of
the number of Options that are being exercised accompanied by payment in full of the Exercise Price applicable to the Options so exercised. Such notice shall be delivered either (a) in writing to the Company at its principal office or at such
other address as may be established by the Committee, to the attention of the Company’s General Counsel or (b) to a third-party plan administrator as may be arranged for by the Company or the Committee from time to time for purposes of the
administration of outstanding Options under the Plan, in the case of either (a) or (b), as communicated to the Participant by the Company from time to time. Payment of the aggregate Exercise Price may be made using any of the methods described
in Section 7(d)(i) or (ii) of the Plan; provided, that the Participant may not use the methods described in Section 7(d)(ii)(A) or (C) of the Plan unless specifically authorized by the Committee. 

  
 4 

 5. Issuance of Shares of Common Stock. Following the exercise of an Option
hereunder, as promptly as practical after receipt of such notification and full payment of such Exercise Price and any required income or other tax withholding amount (as provided in Section 14 hereof), the Company shall issue or transfer, or
cause such issue or transfer, to the Participant the number of shares of Common Stock with respect to which the Options have been so exercised, and shall either (a) deliver, or cause to be delivered, to the Participant a certificate or
certificates therefor, registered in the Participant’s name or (b) cause such shares of Common Stock to be credited to the Participant’s account at the third party stock plan administrator. 

6. Company; Participant. 

(a) The term “Company” as used in this Option Agreement (including any Exhibit attached hereto) with reference to employment shall
include the Company and its Subsidiaries. 
 (b) Whenever the word “Participant” is used in any provision of this Option Agreement
under circumstances where the provision should logically be construed to apply to the executors, the administrators, or the person or persons to whom the Options may be transferred by will or by the laws of descent and distribution, the word
“Participant” shall be deemed to include such person or persons. 
 7.
Non-Transferability. The Options are not transferable by the Participant except to Permitted Transferees in accordance with Section 13(b) of the Plan. Except as otherwise provided herein, no
assignment or transfer of the Options, or of the rights represented thereby, whether voluntary or involuntary, by operation of law or otherwise, shall vest in the assignee or transferee any interest or right herein whatsoever, but immediately upon
such assignment or transfer the Options shall terminate and become of no further effect. 
 8. Rights as Shareholder. The
Participant or a Permitted Transferee of the Options shall have no rights as a shareholder with respect to any share of Common Stock covered by an Option until the Participant (or such Permitted Transferee, as applicable) shall have become the
holder of record or the beneficial owner of such share of Common Stock, and no adjustment shall be made for dividends or distributions or other rights in respect of such Share of Common Stock for which the record date is prior to the date upon which
the Participant (or a Permitted Transferee, as applicable) shall become the holder of record or the beneficial owner thereof. 
 9. Tax
Withholding. The provisions of Section 13(d) of the Plan are incorporated herein by reference and made a part hereof. 
 10.
Notice. Every notice or other communication relating to this Option Agreement between the Company and the Participant shall be in writing, and shall be mailed to or delivered to the party for whom it is intended at such address as may
from time to time be designated by such party in a notice mailed or delivered to the other party as herein provided; provided that, unless and until some other address be so designated, all notices or communications by the Participant to the
Company shall be mailed or delivered to the Company at its principal executive office, to the attention of the Company’s General Counsel, and all notices or communications by the Company to the Participant may be given to the Participant

  
 5 

 
personally or may be mailed to the Participant at the Participant’s last known address, as reflected in the Company’s records. Notwithstanding the above, all notices and communications
between the Participant and any third-party plan administrator shall be mailed, delivered, transmitted or sent in accordance with the procedures established by such third-party plan administrator and communicated to the Participant from time to
time. 
 11. No Right to Continued Service. Any questions as to whether and when there has been a Termination shall be
determined in the sole discretion of the Company. This Option Agreement does not confer upon the Participant any right to continue as an employee or service provider to the Company. 

12. Binding Effect. This Option Agreement shall be binding upon the heirs, executors, administrators and successors of the
parties hereto. 
 13. Waiver and Amendments. Except as otherwise set forth in Section 12 of the Plan, any waiver,
alteration, amendment or modification of any of the terms of this Option Agreement shall be valid only if made in writing and signed by the parties hereto; provided, however, that any such waiver, alteration, amendment or modification is
consented to on the Company’s behalf by the Committee. No waiver by either of the parties hereto of their rights hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such
waiver specifically states that it is to be construed as a continuing waiver. 
 14. Clawback / Forfeiture. Notwithstanding
anything to the contrary contained herein or in the Plan, if the Participant has engaged in or engages in any Detrimental Activity, then the Committee may, in its sole discretion, take actions permitted under the Plan, including: (i) canceling
the Options; or (ii) requiring that the Participant forfeit any gain realized on the exercise of the Options or the disposition of any shares of Common Stock received upon exercise of the Options, and repay such gain to the Company. In
addition, if the Participant receives any amount in excess of what the Participant should have received under the terms of this Option Agreement for any reason (including without limitation by reason of a financial restatement, mistake in
calculations or other administrative error), then the Participant shall be required to repay any such excess amount to the Company. Without limiting the foregoing, all Options shall be subject to reduction, cancellation, forfeiture or recoupment to
the extent necessary to comply with applicable law. 
 15. Governing Law and Venue. This Option Agreement shall be construed
and interpreted in accordance with the laws of the State of Delaware, without regard to the principles of conflicts of law thereof. Notwithstanding anything contained in this Option Agreement, the Grant Notice or the Plan to the contrary, if any
suit or claim is instituted by the Participant or the Company relating to this Option Agreement, the Grant Notice or the Plan, the Participant hereby submits to the exclusive jurisdiction of and venue in the courts of Delaware. 

16. Plan. The terms and provisions of the Plan are incorporated herein by reference. In the event of a conflict or inconsistency
between the terms and provisions of the Plan and the provisions of this Option Agreement (including the Grant Notice), the Plan shall govern and control. 

  
 6 

 17. Restrictive Covenants. The Participant acknowledges and agrees that the
Participant is, or, unless otherwise determined by the Company, will become, party to an agreement with the Company which contains restrictive covenant obligations with respect to the Participant (any such agreement(s), a “Restrictive
Covenant Agreement”). The Participant hereby acknowledges and reaffirms the Participant’s obligations under any such Restrictive Covenant Agreement and hereby acknowledges and agrees that any breach of a Restrictive Covenant
Agreement will constitute Detrimental Activity under the Plan. 
 18. Exhibit for Non-US
Participants. If the Participant is residing and/or working outside of the United States, the Option shall be subject to any special provisions set forth in Exhibit A to this Option Agreement. If the Participant becomes based outside
the United States during the life of the Option, the special provisions set forth in Exhibit A shall apply to the Participant to the extent that the Company determines that the applications of such provisions is necessary or advisable for
legal or administrative reasons. Moreover, if the Participant relocates between any of the countries included on Exhibit A, the special provisions set forth in Exhibit A for such country shall apply to the Participant to the extent
that the Company determines that the applications of such provisions is necessary or advisable for legal or administrative reasons. Exhibit A constitutes part of this Option Agreement. 

19. Data Privacy Acknowledgment. By electing to participate in the Plan via the Company’s acceptance procedures, the
Participant is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Personal Data (as defined below) by the Company and the transfer of Personal Data to the
recipients mentioned herein, including recipients located in countries which do not adduce an adequate level of protection from a European (or other) data protection law perspective, for the purposes described herein. 

(a) Declaration of Consent. The Participant understands that he or she needs to review the following information
about the processing of his or her personal data by or on behalf of the Company, the Participant’s employer or contracting party (the “Employer”) and/or any Subsidiary as described in this Option Agreement and any other
Plan materials (the “Personal Data”) and declare his or her consent. About the processing of the Participant’s Personal Data in connection with the Plan and this Option Agreement, the Participant
understands that the Company is the controller of his or her Personal Data. 
 (b) Data Processing and Legal Basis. The
Company collects, uses and otherwise processes Personal Data about the Participant for the purposes of allocating shares of Common Stock and implementing, administering and managing the Plan. The Participant understands that this Personal Data may
include, without limitation, his or her name, home address and telephone number, email address, date of birth, social insurance number, passport number or other identification number (e.g., resident registration number), salary, nationality, job
title, any shares of stock or directorships held in the Company, details of all Options or any other entitlement to shares of stock or equivalent benefits awarded, cancelled, exercised, vested, unvested or outstanding in the Participant’s
favor. The legal basis for the processing of the Participant’s Personal Data, where required, will be his or her consent. 

  
 7 

 (c) Stock Plan Administration Service Providers. The Participant
understands that the Company may transfer his or her Personal Data, or parts thereof, to a third-party stock plan administrator (and its affiliated companies, as applicable) based in the United States which will assist the Company with the
implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Participant’s Personal Data with such different service provider that serves the Company in a similar
manner. The Participant understands and acknowledges that the Company’s service provider will open an account for him or her to receive and trade shares of Common Stock acquired under the Plan and that he or she will be asked to agree on
separate terms and data processing practices with the service provider, which is a condition of the Participant’s ability to participate in the Plan. 

(d) International Data Transfers. The Participant understands that the Company and, as of the date hereof, any third
parties assisting in the implementation, administration and management of the Plan, such as a third-party stock plan administrator, are based in the United States. The Participant understands and acknowledges that his or her country may have enacted
data privacy laws that are different from the laws of the United States. For example, the European Commission has issued only a limited adequacy finding with respect to the United States that applies solely if and to the extent that companies
self-certify and remain self-certified under the EU/U.S. Privacy Shield program. The Company currently participates in the EU/U.S. Privacy Shield Program. The Company’s legal basis for the transfer of the Participant’s Personal Data is his
or her consent. 
 (e) Data Retention. The Participant understands that the Company will use his or her Personal Data
only as long as is necessary to implement, administer and manage his or her participation in the Plan, or to comply with legal or regulatory obligations, including under tax and securities laws. In the latter case, the Participant understands and
acknowledges that the Company’s legal basis for the processing of his or her Personal Data would be compliance with the relevant laws or regulations. When the Company no longer needs the Participant’s Personal Data for any of the above
purposes, the Participant understands the Company will remove it from its systems. 
 (f) Voluntariness and Consequences of
Denial/Withdrawal of Consent. The Participant understands that his or her participation in the Plan and his or her consent is purely voluntary. The Participant may deny or later withdraw his or her consent at any time, with future
effect and for any or no reason. If the Participant denies or later withdraws his or her consent, the Company can no longer offer the Participant participation in the Plan or offer other equity awards to the Participant or administer or maintain
such awards and the Participant would no longer be able to participate in the Plan. The Participant further understands that denial or withdrawal of his or her consent would not affect his or her status or salary as an employee or his or her career
and that the Participant would merely forfeit the opportunities associated with the Plan. 
 (g) Data Subject Rights.
The Participant understands that data subject rights regarding the processing of Personal Data vary depending on the applicable law and that, depending on where the Participant is based and subject to the conditions set out in the applicable law,
the Participant may have, without limitation, the rights to (i) inquire whether and 

  
 8 

 
what kind of Personal Data the Company holds about him or her and how it is processed, and to access or request copies of such Personal Data, (ii) request the correction or supplementation
of Personal Data about him or her that is inaccurate, incomplete or out-of-date in light of the purposes underlying the processing, (iii) obtain the erasure of
Personal Data no longer necessary for the purposes underlying the processing, processed based on withdrawn consent, processed for legitimate interests that, in the context of his or her objection, do not prove to be compelling, or processed in non-compliance with applicable legal requirements, (iv) request the Company to restrict the processing of his or her Personal Data in certain situations where the Participant feels its processing is
inappropriate, (v) object, in certain circumstances, to the processing of Personal Data for legitimate interests, and to (vi) request portability of the Participant’s Personal Data that he or she has actively or passively provided to
the Company (which does not include data derived or inferred from the collected data), where the processing of such Personal Data is based on consent or his or her employment and is carried out by automated means. In case of concerns, the
