 Section 11. Time and Manner of Distribution 

 

	 	11.1	 In-Service Distribution Elections 

(a)    The Participant shall elect, on the election form described in Section 5 or through any other method
designated by the Administrator, the time of payment from the options described in this subsection (a) with respect to the amounts In the Participant’s Deferrals Sub-Account relating to Compensation
earned in such Plan Year (such election, a “Deferrals Sub-Account Election”). Such election, once made, shall be binding with respect to the portion of the Participant’s Deferrals Sub-Account to which the election relates, unless changed pursuant to subsection (b) of this Section. The following are the available choices for the time of payment of amounts credited to a Participant’s
Deferrals Sub-Account: 
  

	 	(1)	 A date certain, provided that such date shall be at least two years from the first day of the Plan Year with respect
to which the applicable deferrals are credited to the Participant’s Account; or 

(2)       The Participant’s Termination Date. 

Notwithstanding anything herein to the contrary, if a Participant fails to make a valid Deferrals
Sub-Account Election for a Plan Year, the Participant will be deemed to have elected to commence payment of the portion of his Deferrals Sub-Account attributable to the
deferral of Compensation earned during such Plan Year (and any earnings thereon) on the Participant’s Termination Date. 

(b)    A Participant may elect to change a Deferrals Sub-Account Election,
provided that the following requirements are met: (1) the election to change does not take effect until at least 12 months after the date on which the election is made, (2) the election to change is made at least 12 months prior to the
date on which that payment is scheduled to be made, and (3) in the case of an election related to a distribution not described in Section 11.3 or 11.4, the payment under such election will be made no less than five years from the original
date on which such payment would be made. 
 (3)    Amounts with respect to which a Participant has made the
election described in Section 11.1(a) shall be paid to such Participant in a cash lump sum within thirty days of the earlier of (x) the date elected by the Participant in his Deferrals Sub-Account
Election form with 

  
 5 

 
respect to such amounts, and (y) the Participant’s Termination Date; provided, however, that the Participant shall not have the right to designate the taxable year of
payment, and further provided that if the payment is to be made within thirty days of the Participant’s Termination Date, and the Participant is a Specified Employee, the payment shall be distributed on the first day of the
seventh month after the date of such Specified Employee’s Termination Date (or, if earlier, his or her date of death). 
  

	 	11.2	 Termination Date Distributions 

(a)    The portion of a Participant’s Account for which the election described in Section 11.1(a) was not
made (the “Termination Date Balance”) shall commence to be paid to such Participant within thirty days of the date of the Participant’s Termination Date in the form of payment selected by the Participant on an election form approved
by and received by the Administrator or its designee, provided that the Participant shall not have the right to designate the taxable year of payment. Notwithstanding the foregoing, the Termination Date Balance of a Specified Employee shall commence
to be distributed on the first day of the seventh month after the date of such Specified Employee’s Termination Date (or, if earlier, his or her date of death). 

(b)    The following are the available choices for the form of payment of a Participant’s Account: 

(1)    A single lump sum in cash; or 

(2)    Substantially equal annual cash installments over a period not exceeding 10 years. 

The Participant shall elect, on the election form described in Section 5 or through any other method designated by the
Administrator, the form in which his or her Termination Date Balance shall be paid. Such election, once made, shall be binding with respect to his or her entire Termination Date Balance, unless changed pursuant to subsection (c) of this
Section. Each installment payment shall be considered a separate payment and not one of a series of payments for purposes of Section 409A of the Code. This Section 11.1 and all other provisions of this Plan notwithstanding, if a
Participant fails to elect a form of payment before the date by which an election to defer compensation must first be made by such Participant under Section 4, the Participant’s Termination Date Balance shall be paid in the form of a
single lump sum payment in cash. 

  
 6 

 (c)    A Participant may change the form of payment elected with
regard to his Termination Date Balance by a subsequent election form approved by and received by the Administrator or its designee; provided, that unless otherwise permitted in accordance with Section 409A of the Code, the election to change
may not take effect until at least 12 months after the date the election to change is made and the first payment under such election will be made no less than five years from the original date on which payment of the amount credited to the
Participant’s vested account is to commence. 
 11.3    Death Before Payments Commence or are
Completed 
 If a Participant dies while employed by the Employer or while receiving installment payments, the value of his or
her vested account shall be paid to the Participant’s Beneficiary in a single lump sum cash payment, within 90 days after the Participant’s death, provided that the Participant’s Beneficiary shall not have the right to designate the
taxable year of payment. 
 11.4    Unforeseeable Emergency Distribution 

The Administrator may at any time, upon written request of a Participant, cause to be paid to such Participant, an amount equal to all
or any part of the Participant’s account if the Administrator determines, based on such reasonable evidence that it shall require, that such payment is necessary for the purpose of alleviating the consequences of an Unforeseeable Emergency.
Payments of amounts because of an Unforeseeable Emergency may not exceed the amount necessary to satisfy the Unforeseeable Emergency plus amounts necessary to pay any federal, state, or local taxes or penalties reasonably anticipated as a result of
the distribution after taking into account the extent to which the Unforeseeable Emergency is or may be relieved through reimbursement or compensation from insurance or otherwise, by liquidation of the Participant’s assets (to the extent the
liquidation of such assets would not itself cause severe financial hardship), or by cessation of deferrals under the Plan. The amount of a Participant’s account, as applicable, shall be reduced on a pro rata basis by the amount of any
Unforeseeable Emergency distribution to the Participant.

	12.	 Change of Control Provisions 

(a)     In the event of a “Change of Control” of the Employer, the Participant’s account shall be
paid, as soon as reasonably practicable, and not later than the time specified in Treasury regulation §1.409A-3(j)(4)(ix), to the Participant In a lump sum cash payment. If the Change of Control does not
satisfy the definition of “Change in Control” as defined in Treasury regulation §1.049A-3(i)(5), or otherwise does not constitute a permitted distribution event under Section 409A(a)(2) of
the Code, then, to the extent necessary to comply with Section 409A of the Code, the Participant’s account will be paid at the time and In the form it would have been paid under the Plan absent the occurrence of such Change of Control.

 For purposes of this Section 12, “Change of Control” means any of the following: 

(b)     For purposes of this Section, a Change of Control occurs on the date on which any one person, or more than
one person acting as a group, acquires ownership of stock of the Employer that, together with stock held by such person or group constitutes more than 50% of the total fair market value or total voting power of the stock of the Employer. A change in
the effective control of the Employer occurs on the date on which either: (i) a person, or more than one person acting as a group, acquires ownership of stock of the Employer possessing 30% or more of total voting power of the stock of the
Participating Employer, taking into account all such stock acquired during the 12-month period ending on the date of the most recent acquisition, or (ii) a majority of the members of the Employer’s
Board of Directors is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of such Board of Directors prior to the date of the appointment
or election, but only if no other corporation is a majority shareholder of the Employer. A change in the ownership of a substantial portion of assets occurs on the date on which any one person, or more than one person acting as a group, other than a
person or group of persons that is related to the Participating Employer, acquires assets from the Participating Employer that have a total gross fair market value equal to or more than 40% of the total gross fair market value of all of the assets
of the Participating Employer immediately prior to such acquisition or acquisitions, taking into account all such assets acquired during the 12-month period ending on the date of the most recent acquisition.

(the “claimant”) under the Plan, or the duly authorized representative of any such Participant or Beneficiary, may have a reasonable opportunity to appeal a denied claim to the Administrator for a full and fair review. If a claim for
benefits is denied in whole or in part, the Administrator shall notify the claimant within ninety (90) days after receipt of the claim (or within one hundred eighty (180) days if special circumstances require an extension of time for
processing the claim, and provided written notice indicating the special circumstances and the date by which a final decision is expected to be rendered is given to the claimant within the initial ninety (90) day period). 

  
 9 

 The notice of the denial of the claim shall be written in a manner calculated to be
understood by the claimant and shall set forth the following: 
  

	 	(a)	 the specific reason or reasons for the denial of the claim; 

 

	 	(b)	 the specific references to the pertinent Plan provisions on which the denial is based; 

 

	 	(c)	 a description of any additional material or information necessary to perfect the claim, and an explanation of why
such material or information is necessary;

determination, either the specific rule, guideline, protocol, or other similar criterion, or a statement that such a rule, guideline, protocol, or other similar criterion was relied upon in making the adverse determination and that a copy of such
rule, guideline, protocol, or other criterion will be provided free of charge to the claimant upon request.

denial of a claim in whole or in part, the claimant (or his or her duly authorized representative) shall have the right to submit a written request to the Administrator for a full and fair review of the denied claim, to be permitted, upon request
and free of charge, to review and receive copies of documents, records and other information pertinent to the denial, and to submit issues and comments in writing, documents, records, and other information relating to the claim for benefits. Any
appeal of the denial must be given to the Administrator within the period of time prescribed above. The full and fair review shall take into account all comments, documents, records and other 

  
 10 

 
information submitted by the claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination, and provide a review that
does not afford deference to the Initial benefit determination. If the claimant (or the claimant’s duly authorized representative) falls to appeal the denial to the Administrator within the prescribed time, the Administrator’s adverse
determination shall be final, binding and conclusive, to the extent permitted by law. 
 The Administrator may hold a hearing or
otherwise ascertain such facts as it deems necessary and shall render a decision which shall be binding upon both parties, to the extent permitted by law. The Administrator shall advise the claimant of the results of the review within sixty

requiring the extension of time and the date by which the Plan expects to render the determination on review. In the event that a period of time is extended as permitted pursuant to this paragraph due to a claimant’s failure to submit
information necessary to decide a claim, the period for making the benefit determination on review shall be tolled from the date on which the notification of the extension is sent to the claimant until the date on which the claimant responds to the
request for additional information. The decision of the review shall be written in a manner calculated to be understood by the claimant and shall include: 
  

	 	(a)	 specific reasons for the decision;

payments under the Plan constitutes solely an unsecured (but legally enforceable) promise of the Employer to make such payments, and no person, including any Participant or Beneficiary, shall have any lien, prior claim or other security interest in
any property of the Employer as a result of this Plan. Any amounts payable under the Plan shall be paid out of the general assets of the Employer and each Participant and Beneficiary shall be deemed to be a general unsecured creditor of the
Employer. 
  

	 	15.2	 Rabbi Trust 

The Employer may create a grantor trust to pay its obligations hereunder (a so-called rabbi
trust), the assets of which shall be treated, for all purposes, as the assets of the Employer. In the event the trustee of such trust is unable or unwilling to make payments directly to Participants and Beneficiaries and such trustee remits payments
to the Employer for delivery to Participants and Beneficiaries, the Employer shall promptly remit such amount, less applicable income and other taxes required to be withheld, to the Participant or Beneficiary. 

  
 12 

 Section 16.     Amendment and termination 

The Board may, in its sole discretion, amend, suspend or terminate, in whole or in part, the Plan, except that no amendment, suspension, or termination
shall retroactively impair or otherwise adversely affect the rights of any Participant, Beneficiary, or other person to benefits under the Plan which have accrued prior to the date of such action, as determined by the Administrator in its sole
discretion. Anything in this Plan to the contrary notwithstanding, the Plan shall permit an acceleration of the time and form of a payment of the benefits payable under the Plan in accordance with the termination of this Plan. Any termination of
this Plan will be made only to the extent and in the circumstances described in Treas. Reg. §1.409A-3(j)(4)(ix), or any successor provision. 

The Administrator may adopt any amendment or take any other action which may be necessary or appropriate to facilitate the administration, management,
and interpretation of the Plan or to conform the Plan thereto. 
 Section 17.     No Assignment 

A Participant’s right to the amount credited to his or her account under the Plan shall not be subject in any manner to anticipation, alienation,
sale, transfer, assignment, pledge, encumbrance, attachment or garnishment by creditors of the Participant or the Participant’s Beneficiary. 

Section 18.     Successors and Assigns 

The provisions of this Plan shall be binding upon and inure to the benefit of the Employer, its successors and assigns, and the Participants,
Beneficiaries, heirs, legal representatives and assigns. 
 Section 19.     No Contract of Employment 

Nothing contained herein shall be construed as a contract of employment between a Participant and the Employer, or as a right of the Participant to
continue in employment with the Employer, or as a limitation of the right of the Employer to discharge the Participant at any time, with or without cause. 

  
 13 

 Section 20.     Governing Law 

This Plan shall be subject to and construed in accordance with the provisions of ERISA, where applicable, and otherwise by the laws of the State of
Ohio. 
 Section 21.     Section 409A of the Code 

It is intended that the Plan (including all amendments thereto) comply with the provisions of Section 409A of the Code, so as to prevent the
inclusion in gross income of any amount credited to a Participant’s account hereunder in a taxable year that is prior to the taxable year or years in which such amount would otherwise be actually distributed or made available to the
Participant. It is intended that the Plan shall be administered In a manner that will comply with Section 409A of the Code. Any reference in this Plan to Section 409A of the Code will also include any regulations or any other formal
guidance, promulgated with respect to such Section 409A by the U.S. Department of Treasury or the Internal Revenue Service.

required to be withheld from a Participant or Beneficiary.

under the Plan to a Committee in its sole discretion and such Committee shall have the authority to administer the Plan with respect to the specific duties delegated to it. The Plan may be administered by different administrative bodies with respect
to different classes of Participants. The Board may also from time to time authorize a subcommittee consisting of one or more members of the Board (including members who are Employees) or Employees to grant Awards to persons who are not

limitations as the Board may specify and to the requirements of Applicable Law. 

  

	 	(b)	 Committee Composition. If a Committee has been appointed pursuant to this Section 4, such Committee
shall continue to serve in its designated capacity until otherwise directed by the Board. Such Committee shall consist of two (2) or more persons, each of whom qualifies as a “non-employee
director” (within the meaning of Rule 16b-3) and as “independent” as required by the rules of any Stock Exchange on which the Common Stock is listed, in each case if and to the extent required

appoint new members in substitution therefor, fill vacancies (however caused) and dissolve a Committee and thereafter directly administer the Plan, all to the extent permitted by the Applicable Laws and to the extent permitted or required by Rule 16b-3. All of the powers and responsibilities of the Committee under the Plan may be delegated by the Committee, in writing, to any subcommittee thereof, in which case the acts of such subcommittee shall be deemed
to be acts of the Committee hereunder. 

  

	 	(c)	 Powers of the Administrator. Subject to the provisions of the Plan and, in the case of a Committee, the
specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its sole discretion: 

  

	 	(i)	 to administer the Plan and to adopt, amend and rescind from time to time rules and regulations for the
administration of the Plan; 

  

	 	(ii)	 to determine the Fair Market Value of the Common Stock; provided that such determination shall be
applied consistently with respect to Participants under the Plan; 

  
 7 

	 	(iii)	 to select the Employees, Non-Employee Directors and Consultants to whom
Awards may from time to time be granted; 

  

	 	(iv)	 to determine the number of Shares to be covered by each Award (other than a cash-based Other Award), and the
amount of cash to be covered by each cash-based Other Award; 

  

	 	(v)	 to approve the form(s) of Award Agreement(s) and other related documents used under the Plan;

  

	 	(vi)	 to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted
hereunder, which terms and conditions include but are not limited to the exercise or purchase price, the time or times when Awards may vest and/or be exercised (which may be based on service and/or performance criteria), the circumstances (if any)
when vesting will be accelerated or forfeiture restrictions will be waived, and any restriction or limitation regarding any Award (including any blackout); 

  

	 	(vii)	 to amend, waive or otherwise adjust the terms and conditions of any outstanding Award, any Award Agreement or
any other agreement related to an Award, including any amendment adjusting vesting or exercisability (e.g., in connection with a change in the terms or conditions under which such person is providing services to the Company); provided that no
such amendment, waiver or adjustment shall be made that would materially and adversely affect the rights of any Participant with respect to such Award without such Participant’s consent; and provided, further, that the
Administrator shall not have any such authority to the extent that the grant of such authority would cause any tax to become due under Section 409A of the Code; 

 

	 	(viii)	 to (A) extend the term of any Award, including, without limitation, extending the period following a
termination of a Participant’s Continuous Service Status during which any such Award may remain outstanding or (B) provide for the accrual of dividends or dividend equivalents with respect to any such Award; provided that the
Administrator shall not have any such authority to the extent that the grant of such authority would cause any tax to become due under Section 409A of the Code; 

 

	 	(ix)	 to approve addenda pursuant to Section 4(d) hereof or to grant Awards to, or to modify the terms of any
outstanding Award Agreement or any agreement related to any Option, Restricted Stock, Restricted Stock Unit or Other Award held by, Participants who are foreign nationals or employed outside of the United States with such terms and conditions as the
Administrator deems necessary or appropriate to accommodate differences in local law, tax policy or custom which deviate from the terms and conditions set forth in this Plan to the extent necessary or appropriate to accommodate such differences;

  
 8 

	 	(x)	 to construe and interpret the terms of the Plan, any Award Agreement and any agreement related to any Option,
Restricted Stock, Restricted Stock Unit or Other Award, which constructions, interpretations and decisions shall be final and binding on all Participants; and 

 

	 	(xi)	 to exercise discretion to take or make any and all other actions or determinations which it determines to be
necessary or advisable for the administration of the Plan. 

  

	 	(d)	 Addenda. The Administrator may approve such addenda to the Plan as it may consider necessary or
appropriate for the purpose of granting Awards to Employees, Non-Employee Directors or Consultants, which Awards may contain such terms and conditions as the Administrator deems necessary or appropriate to
accommodate differences in local law, tax policy or custom, which, if so required under Applicable Laws, may deviate from the terms and conditions set forth in this Plan. The terms of any such addenda shall supersede the terms of the Plan to the
extent necessary to accommodate such differences but shall not otherwise affect the terms of the Plan as in effect for any other purpose. 

  

	 	(e)	 Delegation of Administration of the Plan. The Administrator may delegate the administration of the Plan
to one or more officers or employees of the Company, and such delegate administrator(s) may have the authority to execute and distribute Award Agreements, to maintain records relating to Awards, to process or oversee the issuance of Common Stock
under Awards, to interpret and administer the terms of Awards and to take such other actions as may be necessary or appropriate for the administration of the Plan and of Awards under the Plan; provided that in no case shall any such delegate
administrator be authorized (i) to grant Awards under the Plan (except in connection with any delegation made by the Administrator pursuant to Section 4(a) hereof), (ii) to take any action inconsistent with Section 409A of the
Code or (iii) to take any action inconsistent with Applicable Law. Any action by any such delegate administrator within the scope of its delegation shall be deemed for all purposes to have been taken by the Administrator and, except as
otherwise specifically provided, references in this Plan to the Administrator shall include any such delegate administrator. The Administrator, and, to the extent it so provides, any subcommittee, shall have sole authority to determine whether to
review any actions and/or interpretations of any such delegate administrator, and if the Administrator shall decide to conduct such a review, any such actions and/or interpretations of any such delegate administrator shall be subject to approval,
disapproval or modification by the Administrator. 

  
 9 

	 	(f)	 Indemnification. To the maximum extent permitted by Applicable Laws, each member of the Committee
(including officers of the Company, if applicable), or of the Board, as applicable, or any Employee to whom the Board has delegated some or all of its powers pursuant to the terms hereof, shall be indemnified and held harmless by the Company against
and from (i) any loss, cost, liability or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit or proceeding to which he or she may be a party or in which he or she
may be involved by reason of any action taken or failure to act under the Plan or pursuant to the terms and conditions of any Award except for actions taken in bad faith or failures to act in good faith, and (ii) any and all amounts paid by him
or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit or proceeding against him or her; provided that such member shall give the Company an
opportunity, at its own expense, to handle and defend any such claim, action, suit or proceeding before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other
rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation, Certificate of Incorporation or Bylaws, by contract, as a matter of law or otherwise, or under any other power that the Company may
have to indemnify or hold harmless each such person. 

  

	 	(g)	 Decisions of the Administrator. Decisions of the Administrator shall be final, binding and conclusive on
all parties. For the avoidance of doubt, the Administrator may exercise all discretion granted to it under the Plan in a non-uniform manner among Participants and Awards, and the Administrator may take
different actions with respect to the vested and unvested portions of an Award. 

  

	 	(h)	 Shareholder Approval Required for Repricing. Notwithstanding any provision of this Plan to the contrary,
in no event shall (i) any repricing (within the meaning of U.S. generally accepted accounting principles or any applicable Stock Exchange rule) of Options issued under the Plan be permitted at any time under any circumstances, (ii) any new
Awards be issued in substitution for outstanding Options previously granted to Participants if such action would be considered a repricing (within the meaning of U.S. generally accepted accounting principles or any applicable Stock Exchange rule) or
(iii) any Option or stock appreciation right (x) have its exercise price be reduced or (y) be purchased (or otherwise “cashed out”) by the Company if, on the date of such purchase, the exercise price per Share covered by
such Option or stock appreciation right is less than 100% of the Fair Market Value of a Share on such date, in the case of each (i)-(iii), unless the approval of the holders of capital stock of the Company has been obtained to take such action.

  
 10 

	5.	 Stock Available for Awards. 

 

	 	(a)	 Available Shares. Subject to adjustment under Section 11, the maximum number of Shares available
for the grant of Awards under the Plan is 27,900,000 Shares, of which a maximum of 27,900,000 Shares may be issued in the aggregate pursuant to the exercise of Incentive Stock Options. Shares issued under the Plan may consist in whole or in part of
authorized but unissued Shares, reacquired Shares or treasury Shares, as the Administrator determines in its sole discretion. If an Award should expire or become unexercisable for any reason without having been exercised in full, the unissued Shares
that were subject to such Award shall, unless the Plan shall have been terminated, continue to be available under the Plan for issuance pursuant to future Awards. In addition, any Shares which are retained by the Company upon exercise of an Award or
surrendered (either directly or by stock attestation) by the Participant to the Company, in each case, in order to satisfy the exercise or purchase price for such Award or any Tax Withholding Obligations with respect to such Award shall be treated
as not issued and shall continue to be available under the Plan for issuance pursuant to future Awards. Shares issued under the Plan that are later forfeited to the Company due to the failure to vest or that are repurchased by the Company at the
original purchase price paid to the Company for the Shares (including, without limitation, upon forfeiture to or repurchase by the Company in connection with the termination of a Participant’s Continuous Service Status) shall, in each case,
again be available for future grant under the Plan. Notwithstanding the foregoing, subject to the provisions of Section 11 hereof, in no event shall the maximum aggregate number of Shares that may be issued under the Plan pursuant to Incentive
Stock Options exceed the number set forth in the first sentence of this Section 5(a). Shares covered by Awards granted pursuant to the Plan in connection with the assumption, replacement, conversion or adjustment of outstanding equity-based
awards in the context of a corporate acquisition or merger (within the meaning of any applicable Stock Exchange rule) shall not count as issued under the Plan for purposes of this Section 5(a). 

 

	 	(b)	 Limits Applicable to Non-Employee Directors. The maximum
number of Shares subject to Awards (and of cash subject to cash-based Other Awards) granted under the Plan or otherwise during any one calendar year to any Non-Employee Director for service on the Board,
(exclusive of any cash fees paid by the Company to such Non-Employee Director during such calendar year for service on the Board), will not exceed $500,000 in total value (calculating the value of any such
Awards based on the grant date fair value of such Awards for financial reporting purposes). 

  

	 	(c)	 ISO $100,000 Limitation. Notwithstanding any designation under Section 6(a), to the extent that the
aggregate Fair Market Value of Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary)
exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the order in

  
 11 

	 	
which they were granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 

 

	6.	 Stock Options. 

 

	 	(a)	 General. The Administrator may from time to time grant Options on such terms as it shall determine,
subject to the terms and conditions set forth in the Plan. The Award Agreement shall clearly identify such Option as either an Incentive Stock Option or a Nonstatutory Stock Option. 

 

	 	(b)	 Term of Option. The term of each Option shall be the term stated in the Award Agreement; provided
that the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Award Agreement; and provided, further, that, in the case of an Incentive Stock Option granted to a
person who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Award Agreement. 

 

	 	(c)	 Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an
Option shall be such price as is determined by the Administrator and set forth in the Award Agreement, but shall be subject to the following: 

  

	 	(i)	 In the case of an Incentive Stock Option: 

 

	 	(1)	 granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise price shall be
no less than 110% of the Fair Market Value on the date of grant; or 

  

	 	(2)	 granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value
on the date of grant; 

  

	 	(ii)	 in the case of a Nonstatutory Stock Option, the per Share exercise price shall be such price as is determined
by the Administrator, provided that, if the per Share exercise price is less than 100% of the Fair Market Value on the date of grant, it shall otherwise comply with all Applicable Laws, including Section 409A of the Code; and

  

	 	(iii)	 notwithstanding the foregoing, Options may be granted (or assumed) with a per Share exercise price other than
as required above pursuant to a merger or other corporate transaction. 

  

	 	(d)	 Permissible Consideration. The consideration to be paid for the Shares to be issued upon exercise of an
Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option and to the extent required by Applicable Laws, shall be determined at the time of grant) and may consist entirely of
(1) cash; (2) check; (3) other previously owned 

  
 12 

	 	
Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised; (4) a Cashless Transaction;
(5) such other consideration and method of payment permitted under Applicable Laws; or (6) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall
consider if acceptance of such consideration may be reasonably expected to benefit the Company, and the Administrator may, in its sole discretion, refuse to accept a particular form of consideration at the time of any Option exercise.

  

	 	(e)	 Exercise of Options. 

 

	 	(i)	 Exercisability. Any Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, consistent with the terms of the Plan and reflected in the Award Agreement, including vesting criteria. Any such vesting criteria may be based upon the achievement of Company-wide, business unit, or
individual goals (including, but not limited to, Continuous Service Status), or any other basis determined by the Administrator in its sole discretion. Each Option shall be exercisable in whole or in part. The partial exercise of an Option shall not
cause the expiration, termination or cancellation of the remaining portion thereof. 

  

	 	(ii)	 Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The
Administrator may require that an Option be exercised as to a minimum number of Shares or a minimum aggregate exercise price; provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which
the Option is then exercisable. 

  

	 	(iii)	 Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice (which
may be in electronic form) of such exercise has been received by the Company in accordance with the terms of the Award Agreement from the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to
which the Option is exercised and the person entitled to exercise the Option has paid, or made arrangements to satisfy, any Tax Withholding Obligations in accordance with Section 9 hereof. The exercise of an Option shall result in a decrease in
the number of Shares that thereafter may be available, both for purposes of the Plan and for purchase under the Option, by the number of Shares as to which the Option is exercised. 

  
 13 

	 	(iv)	 Rights as Holder of Capital Stock. Until the issuance of the Shares (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a holder of capital stock shall exist with respect to the Shares underlying an Option. No
adjustment to the Shares underlying an Option will be made for a dividend or other right for which the record date is prior to the date of issuance of such Shares, except as provided in Section 11 hereof. 

 

	 	(v)	 No Obligation to Exercise. The grant to a Participant of an Option shall impose no obligation upon such
Participant to exercise such Option. 

  

	 	(vi)	 Incentive Stock Option Exercise. In the event the holder of an Incentive Stock Option is no longer an
Employee of the Company or of a Subsidiary but remains an Employee, such Incentive Stock Option shall be considered a Nonstatutory Stock Option as of the date that is three months following the relevant employment transition out of such
Participant’s role as an Employee of the Company or of a Subsidiary if not exercised by such date. 

  

	 	(f)	 Termination of Continuous Service Status. The Administrator shall establish and set forth in the
applicable Award Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an Optionee’s Continuous Service Status, which provisions may be waived or modified by the Administrator at
any time. To the extent that an Award Agreement does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s Continuous Service Status, the following provisions shall apply:

  

	 	(i)	 General Provisions. If the Optionee (or other person entitled to exercise the Option) does not exercise
the Option to the extent so entitled within the time specified below, the Option shall terminate and the Shares underlying the unexercised portion of the Option shall revert to the Plan. In no event may any Option be exercised after the expiration
of the Option term as set forth in the Award Agreement (and subject to Section 6(b) hereof). 

  

	 	(ii)	 Termination other than Upon Disability or Death or for Cause. In the event of termination of an
Optionee’s Continuous Service Status other than under the circumstances set forth in subsections (iii) through (v) below, such Optionee may exercise any outstanding Option at any time within thirty (30) days following such termination
to the extent the Optionee is vested in such Option. The unvested portion of any outstanding Option held by such Optionee shall immediately terminate upon the termination of the Optionee’s Continuous Service Status. 

  
 14 

	 	(iii)	 Disability of Optionee. In the event of termination of an Optionee’s Continuous Service Status as a
result of his or her Disability, such Optionee may exercise any outstanding Option at any time within six (6) months following such termination to the extent the Optionee is vested in such Option. The unvested portion of any outstanding Option
held by such Optionee shall immediately terminate upon the termination of the Optionee’s Continuous Service Status. 

  

	 	(iv)	 Death of Optionee. In the event of the death of an Optionee during the period of Continuous Service
Status since the date of grant of any outstanding Option, or within thirty (30) days following termination of Optionee’s Continuous Service Status, the Option may be exercised by any beneficiaries designated in accordance with
Section 20 hereof, or if there are no such beneficiaries, by the Optionee’s estate, or by a person who acquired the right to exercise the Option by bequest or inheritance, at any time within twelve (12) months following the date of
death or, if earlier, the date the Optionee’s Continuous Service Status terminated, but only to the extent the Optionee is vested in such Option. The unvested portion of any outstanding Option held by such Optionee shall immediately terminate
upon the termination of the Optionee’s Continuous Service Status. 

  

	 	(v)	 Termination for Cause. In the event of termination of an Optionee’s Continuous Service Status for
Cause, any outstanding Option (including any vested portion thereof) held by such Optionee shall immediately terminate in its entirety upon first notification to the Optionee of termination of the Optionee’s Continuous Service Status for Cause.
If an Optionee’s Continuous Service Status is suspended pending an investigation of whether the Optionee’s Continuous Service Status will be terminated for Cause, all the Optionee’s rights under any Option, including the right to
exercise the Option, shall be suspended during the investigation period. 

  

	7.	 Restricted Stock; Restricted Stock Units. 

 

	 	(a)	 Restricted Stock. 

 

	 	(i)	 Rights to Purchase or Receive. When a right to purchase or receive Restricted Stock is granted under the
Plan, the Company shall advise the recipient in writing (which may be in electronic form) of the terms, conditions and restrictions applicable to the offer or grant, including the number of Shares that such person shall be entitled to purchase or
receive and the price to be paid, if any (which shall be as determined by the Administrator, subject to Applicable Laws, including any applicable securities laws) The permissible consideration for Restricted Stock shall be determined by the
Administrator and shall be the same as is set forth in Section 6(d) with respect to exercise of Options. 

  
 15 

	 	(ii)	 Vesting Terms. The Restricted Stock shall vest at such rate or based on such criteria as the
Administrator may determine. Any such vesting criteria may be based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, Continuous Service Status), or any other basis determined by the
Administrator in its sole discretion. Notwithstanding the foregoing, at any time after the delivery of Restricted Stock, the Administrator, in its sole discretion, may reduce or waive any applicable vesting criteria. 

 

	 	(iii)	 Termination of Continuous Service Status. Unless otherwise provided in the applicable Award Agreement,
in the event the Participant’s Continuous Service Status is terminated for any reason (including death or Disability) prior to the vesting of a Share of Restricted Stock, such Share shall be (i) forfeited for no consideration, in the event
it was granted to the Participant, or (ii) subject to a repurchase option exercisable by the Company at the lower of the current Fair Market Value of a Share of Restricted Stock or the original purchase price paid by the Participant, in the
event it was purchased by the Participant. 

  

	 	(iv)	 Other Provisions. The Award Agreement shall contain such other terms, provisions and conditions not
inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 

  

	 	(v)	 Rights as a Holder of Capital Stock. Unless otherwise provided in the applicable Award Agreement, once
the Restricted Stock is purchased or received, the Participant shall have the rights equivalent to those of a holder of capital stock, and shall be a record holder when his or her purchase and/or the issuance of the Shares is entered upon the
records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Restricted Stock is purchased or received. 

 

	 	(b)	 Restricted Stock Units. 

 

	 	(i)	 Award Terms. When Restricted Stock Units are granted under the Plan, the Company shall advise the
recipient in writing (which may be in electronic form) of the terms, conditions and restrictions applicable to the Award, including the number of Restricted Stock Units that such person shall be entitled to receive. 

 

	 	(ii)	 Vesting and Settlement. The Administrator may, in its sole discretion, set vesting criteria for
the Restricted Stock Units that must be met in order to be eligible to receive a payout pursuant to the Award (note that the Administrator may specify additional conditions which must also be met in order to receive a payout pursuant to the Award).
Any such vesting criteria may be based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, Continuous 

  
 16 

	 	
Service Status), or any other basis determined by the Administrator in its sole discretion. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the
Administrator, in its sole discretion, may reduce or waive any applicable vesting criteria. 

  

	 	(iii)	 Form and Timing of Settlement. Settlement of earned Restricted Stock Units will be made upon the date(s)
or event(s) determined by the Administrator and may be subject to additional conditions, if any, each as set forth in the applicable Award Agreement. The Administrator, in its sole discretion, may provide for the settlement of earned Restricted
Stock Units in cash, Shares, or a combination of both. In addition, the Administrator may, in its discretion, provide that settlement of Restricted Stock Units shall be deferred, on a mandatory basis or at the election of the Participant in a manner
that complies with Section 409A of the Code. 

  

	 	(iv)	 Termination of Continuous Service Status. Unless otherwise provided in the applicable Award Agreement,
in the event the Participant’s Continuous Service Status is terminated for any reason (including death or Disability) prior to the vesting of a Restricted Stock Unit, such Restricted Stock Unit shall be forfeited for no consideration.

  

	 	(v)	 Other Provisions. The applicable Award Agreement shall contain such other terms, provisions and
conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 

  

	 	(vi)	 Rights as a Holder of Capital Stock. Until the issuance of the Shares (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company) (if any), no right to vote or receive dividends or any other rights as a holder of capital stock shall exist with respect to the Restricted Stock Units;
provided, however, that the applicable Award Agreement may provide Participants with the right to receive dividend equivalents that may be settled in cash and/or Shares and which shall be subject to the same restrictions on transfer
and forfeitability as the Restricted Stock Units with respect to which paid, in each case to the extent provided in the Award Agreement. No adjustment will be made for a dividend or other right for which the record date is prior to the date of
issuance, except as provided in Section 11 hereof. 

  

	8.	 Other Awards. 

 

	 	(a)	 General. The Administrator may from time to time grant cash-based (including annual incentive awards),
equity-based or equity-related awards not otherwise described herein in such amounts and on such terms as it shall determine, subject to the terms and conditions set forth in the Plan. Without limiting the
generality of the preceding sentence, each such Other Award may (i) involve the transfer of 

  
 17 

	 	
actual Shares to Participants, either at the time of grant or thereafter, or payment in cash or otherwise, (ii) be subject to performance-based vesting conditions and/or multipliers and/or
service-based vesting conditions, (iii) be in the form of cash, stock appreciation rights, phantom stock, performance shares, deferred share units, share-denominated performance units or other similar awards and (iv) be designed to comply
with Applicable Laws of jurisdictions other than the United States; provided that each cash-based Other Award shall be denominated in cash and each equity-based or equity-related Other Award shall be denominated in, or shall have a value
determined by reference to, a number of Shares, in each case that is specified (or will be determined using a formula that is specified) at the time of the grant of such Other Award. 

 

	 	(b)	 Award Terms. When Other Awards are granted under the Plan, the Company shall advise the recipient in
writing (which may be in electronic form) of the terms, conditions and restrictions applicable to the Other Award. 

  

	 	(c)	 Vesting, Settlement and Payment. The Administrator may, in its sole discretion, set vesting
criteria for the Other Award that must be met in order to be eligible to receive a payout pursuant to the Award (note that the Administrator may specify additional conditions which must also be met in order to receive a payout pursuant to the
Award). Any such vesting criteria may be based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, Continuous Service Status), or any other basis determined by the Administrator in its sole
discretion. Notwithstanding the foregoing, at any time after the grant of the Other Award, the Administrator, in its sole discretion, may reduce or waive any applicable vesting criteria. 

 

	 	(d)	 Form and Timing of Settlement or Payment. Settlement or payment of earned Other Awards will be made upon
the date(s) or event(s) determined by the Administrator and may be subject to additional conditions, if any, each as set forth in the applicable Award Agreement. The Administrator will settle earned cash-based Other Awards solely in cash but, in its
sole discretion, may settle earned equity-based or equity-related Other Awards in cash, Shares, or a combination of both. 

  

	 	(e)	 Other Provisions. The Award Agreement for Other Awards shall contain such other terms, provisions and
conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 

  

	 	(f)	 Rights as a Holder of Capital Stock. Until the issuance of the Shares (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company) (if any), no right to vote or receive dividends or any other rights as a holder of capital stock shall exist with respect to the equity-based or equity-related
Other Awards. No adjustment will be made for a dividend or other right for which the record date is prior to the date of issuance, except as provided in Section 11 hereof. 

  
 18 

	9.	 Taxes. 

 

	 	(a)	 As a condition of the grant, vesting and exercise or settlement of an Award, the Participant (or, in the case
of the Participant’s death or a permitted transferee, the person holding, exercising or receiving the proceeds of the Award) shall make such arrangements as the Administrator may require for the satisfaction of any Tax Withholding Obligations
that may arise in connection with such Award. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. 

  

	 	(b)	 The Administrator may, in its sole discretion, permit or require a Participant (or, in the case of the
Participant’s death or a permitted transferee, the person holding, exercising or receiving the proceeds of the Award) to satisfy all or part of his or her Tax Withholding Obligations by remitting cash to the Company, by Cashless Transaction or
by surrendering Shares (either directly or by stock attestation) that he or she previously acquired; provided that, unless specifically permitted by the Administrator (i) any Cashless Transaction must be an approved broker-assisted
Cashless Transaction and the Shares withheld in the Cashless Transaction must be limited to avoid financial accounting charges under applicable accounting guidance, and (ii) any surrendered Shares must have been previously held for at least six
months plus one day. Any payment of taxes by surrendering Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by rules of the Securities and Exchange Commission. In addition, upon the
exercise or settlement of any Award in cash, or the making of any other payment with respect to any Award (other than in Shares), the Company shall have the right to withhold from any payment required to be made pursuant thereto an amount sufficient
to satisfy any Tax Withholding Obligations attributable to such exercise, settlement or payment. 

  

	 	(c)	 The Company will have no duty or obligation to any Participant to advise such holder as to the tax treatment or
time or manner of exercising an Award. Furthermore, the Company will have no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised.
The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award. 

  

	10.	 Non-Transferability of Awards. Unless otherwise
determined by the Administrator, Awards may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by a Participant will
not constitute a transfer. An Option may be exercised, during the lifetime of the holder of the Option, only by such holder or a 

  
 19 

	 	
transferee permitted by this Section 10. Upon the death of a Participant, outstanding Awards granted to such Participant may be exercised only by the executors or administrators of the
Participant’s estate, by any person or persons who shall have acquired such right to exercise by will or by the laws of descent and distribution or by another transferee permitted by the Administrator pursuant to this Section 10;
provided that Incentive Stock Options are not transferable other than by will or by the laws of descent or distribution and, during the lifetime of the holder of the Incentive Stock Option, only by such holder. No transfer by will, the laws
of descent and distribution or otherwise of any Award, or of the right to exercise any Award, shall be effective to bind the Company unless (a) the Administrator shall have been furnished with written notice thereof and with a copy of the will
and/or such evidence as the Administrator may deem necessary to establish the validity of the transfer, (b) if the transfer was other than by will or by the laws of descent or distribution, the Administrator has provided its written consent to
such transfer, and (c) the Administrator shall have been furnished with an agreement by the transferee to comply with all the terms and conditions of the Award that are or would have been applicable to the Participant, to be bound by the
acknowledgements made by the Participant in connection with the grant of the Award and, if the transfer was other than by will or by the laws of descent or distribution, to be bound by any additional conditions the Administrator may, in its sole
discretion, impose. For the avoidance of doubt, to the extent an unvested Award is transferred, the Continuous Service Status of the Participant will continue to determine, without limitation, the vesting and exercisability of such Award, to the
same extent that the Continuous Service Status of the Participant would have done so had the Participant continued to directly hold such Award. 

  

	11.	 Adjustments Upon Changes in Capitalization, Merger or Certain Other
Transactions. 

  

	 	(a)	 Changes in Capitalization. Subject to any action required under Applicable Laws by the holders of
capital stock of the Company, (i) the numbers and class (or type) of Shares, units representing Shares, or other stock or securities: (x) available for future Awards (including pursuant to Incentive Stock Options) under Section 5
hereof and (y) covered by each outstanding Award, (ii) the price per Share covered by each such outstanding Option, and (iii) any repurchase price per Share applicable to Shares issued pursuant to any Award, shall be proportionately
adjusted (or substituted) by the Administrator in the event of a stock split, reverse stock split, stock dividend, combination, consolidation, recapitalization, or reclassification of the Shares, extraordinary dividend of cash or other property,
subdivision of the Shares, exchange of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, change in corporate structure, other increase or
decrease in the number of Shares or other similar occurrence. Any adjustment by the Administrator pursuant to this Section 11(a) shall be made in the Administrator’s sole discretion and shall be final, binding and conclusive. Except as
expressly 

  
 20 

	 	
provided herein, (I) no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason
thereof shall be made with respect to, the number or price of Shares subject to, or the terms related to, an Award, and (II) no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the
payment of any dividends or dividend equivalents, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger or consolidation of the Company or any other corporation. If, by reason of a transaction
described in this Section 11(a) or an adjustment pursuant to this Section 11(a), a Participant’s Award Agreement or agreement related to any Share relating to or underlying an Award covers additional or different shares of stock or
securities (or units representing additional or different shares of stock or securities), then such additional or different shares (and the units representing such additional or different shares), and the Award Agreement or agreement related to the
Shares underlying an Award, shall be subject to all of the terms, conditions and restrictions which were applicable to the Award or Shares underlying the Award prior to such adjustment. 

 

	 	(b)	 Dissolution or Liquidation. In the event of the dissolution or liquidation of the Company, each Award
will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 

  

	 	(c)	 Corporate Transactions. In the event of (i) a transfer of all or substantially all of the
Company’s assets, (ii) a merger, consolidation or other capital reorganization or business combination transaction of the Company with or into another corporation, entity or person, or (iii) the consummation of a transaction, or
series of related transactions, in which any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 of the
Exchange Act), directly or indirectly, of more than 50% of the total Voting Power of the Company (each transaction set forth in clauses (i) through (iii) hereof, a “Corporate Transaction”), each outstanding Award (vested or
unvested) will be treated as the Administrator determines, which determination may be made without the consent of any Participant and need not treat all outstanding Awards (or portion thereof) in an identical manner. Such determination, without the
consent of any Participant, may provide (without limitation) for one or more of the following in the event of a Corporate Transaction: (A) the continuation of such outstanding Awards by the Company (if the Company is the surviving corporation);
(B) the assumption of such outstanding Awards by the surviving corporation or its parent; (C) the substitution by the surviving corporation or its parent of new awards for such Awards; (D) the cancellation of such Awards in exchange for a
payment to the Participants equal to the excess (if any) of (1) the Fair Market Value of the Shares subject to such Awards as of the closing date 

  
 21 

	 	
of such Corporate Transaction (which may, for this purpose, be determined by reference to the value, as determined by the Administrator, of the property (including cash) received by the holder of
a Share as a result of such Corporate Transaction) over (2) the exercise price or purchase price paid or to be paid for the Shares subject to the Awards (if any); or (E) the cancellation of any outstanding Awards for no consideration.

  

	 	(d)	 Savings Clause. No provision of this Section 11 shall be given effect to the extent that such
provision would cause any tax to become due under Section 409A of the Code. Furthermore, no provision of this Section 11 shall be given effect to the extent such provision would result in short-swing profits liability under Section 16
of the Exchange Act or violate the exemptive conditions of Rule 16b-3. 

  

	12.	 Change in Control. The consequences of a Change in Control, if any, with respect to an Award will
be set forth in the applicable Award Agreement. 

  

	13.	 Time of Granting of Awards. The date of grant of an Award shall, for all purposes, be the date on
which the Administrator makes the determination granting such Award, or such other date as is determined by the Administrator. 

  

	14.	 Amendment and Termination of the Plan. The Board may at any time amend or terminate the Plan, but
no amendment or termination (other than an adjustment pursuant to Section 11 hereof) shall be made that would materially and adversely affect the rights of any Participant under any outstanding Award, without his or her consent. The preceding
sentence shall not restrict the Administrator’s ability to exercise its discretionary authority hereunder, which discretion may be exercised without amendment to the Plan. No provision of this Section 14 shall be given effect to the extent
that such provision would cause any tax to become due under Section 409A of the Code. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain the approval of holders of capital stock with
respect to any Plan amendment in such a manner and to such a degree as required. 

  

	15.	 Recoupment. Notwithstanding anything in the Plan or in any Award Agreement to the contrary, the
Company will be entitled to the extent permitted or required by Applicable Law, any Company policy that is or may be adopted and/or the requirements of a Stock Exchange on which the Shares are listed for trading, in each case, as in effect from time
to time, to recoup compensation of whatever kind paid by the Company at any time to a Participant under this Plan. No such recoupment of compensation will be an event giving rise to a right to resign for “good reason” or “constructive
termination” (or similar term) under any agreement between any Participant and the Company. 

  

	16.	 Changes in Status & Leaves of Absence. The Administrator
shall have the discretion to determine (whether by establishing a policy applicable to the treatment of any or all Awards in such circumstances, or by making an individualized determination) at any time whether and to what extent any tolling,
reduction, vesting-extension, forfeiture or other treatment should be applied to an Award in connection with a Participant’s leave of absence or a change in a Participant’s regular level of time commitment to the Company or any of its
Parents, Subsidiaries or Affiliates, 

  
 22 

	 	
as applicable (e.g., in connection with a change from full-time to part-time status); provided, however, that the Administrator shall not have any such discretion (whether pursuant
to a policy or specific determination) to the extent that the grant of such discretion would cause any tax to become due under Section 409A of the Code; and provided, further, that in the absence of a determination to the contrary
by the Administrator, vesting shall continue during any paid leave and shall be tolled during any unpaid leave (in all cases, unless otherwise required by Applicable Laws or unless it would cause any tax to become due under Section 409A of the
Code). In the event of any such tolling, forfeiture, reduction or extension, the Participant shall have no right to the portion of the Award so tolled, forfeited, reduced or extended (except for the right that remains, if any, after the application
of such action). 

  

	17.	 Failure to Comply. In addition to the remedies of the Company elsewhere provided for herein,
failure by a Participant to comply with any of the terms and conditions of the Plan or any Award Agreement, unless such failure is remedied by such Participant within ten days after having been notified of such failure by the Administrator, shall be
grounds for the cancellation and forfeiture of such Award, in whole or in part, as the Administrator, in its sole discretion, may determine. 

  

	18.	 Conditions Upon Issuance of Shares; Securities Matters. The Company shall be under no obligation
to affect the registration pursuant to the Securities Act of 1933, as amended, of any Shares to be issued hereunder or to effect similar compliance under any state, local or non-U.S. laws. Notwithstanding any
other provision of the Plan or any Award Agreement, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with the Applicable Laws,
with such compliance determined by the Company in consultation with its legal counsel. The Administrator may require, as a condition to the issuance of Shares pursuant to the terms hereof, that the recipient of such Shares make such covenants,
agreements and representations, and that any related certificates representing such Shares bear such legends, as the Administrator, in its sole discretion, deems necessary or desirable. The exercise or settlement of any Award granted hereunder shall
only be effective at such time as counsel to the Company shall have determined that the issuance and delivery of Shares pursuant to such exercise or settlement is in compliance with all Applicable Laws. The Company may, in its sole discretion, defer
the effectiveness of any exercise or settlement of an Award granted hereunder in order to allow the issuance of Shares pursuant thereto to be made pursuant to registration or an exemption from registration or other methods for compliance available
under U.S. federal, state, local or non-U.S. securities laws. The Company shall inform the Participant in writing of its decision to defer the effectiveness of the exercise or settlement of an Award granted
hereunder. During the period that the effectiveness of the exercise of an Award has been deferred, the Participant may, by written notice, withdraw such exercise and obtain the refund of any amount paid with respect thereto. 

  
 23 

	19.	 Section 409A. 

 

	 	(a)	 Unless otherwise expressly provided for in an Award Agreement, the Plan and each Award Agreement will be
interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A of the Code, and, to the extent not so exempt, in compliance with Section 409A of the Code. If the
Administrator determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the
consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to
the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the Shares are publicly traded, and if a Participant holding an Award that constitutes “deferred compensation” under Section 409A of the
Code is a “specified employee” for purposes of Section 409A of the Code, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A of the Code without regard
to alternative definitions thereunder) will be issued or paid before the date that is six (6) months following the date of such Participant’s “separation from service” (as defined in Section 409A of the Code without regard
to alternative definitions thereunder) or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code, and any amounts so deferred will be paid
in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original schedule. Each payment provided any Participant in connection with an Award granted hereunder shall be considered a separate payment for
purposes of Section 409A of the Code. 

  

	 	(b)	 With respect to any Award that constitutes nonqualified deferred compensation within the meaning of
Section 409A of the Code, termination of a Participant’s Continuous Service Status shall mean a separation from service within the meaning of Section 409A of the Code, unless the Participant was an Employee immediately prior to such
termination and is then contemporaneously retained as a Consultant or Non-Employee Director pursuant to a written agreement and such agreement provides otherwise. The Continuous Service Status of a Participant
shall be deemed to have terminated for all purposes of the Plan if such person is employed by or provides services to Subsidiary and such Subsidiary ceases to be a Subsidiary, unless the Administrator determines otherwise. To the extent permitted by
Section 409A of the Code, a Participant who ceases to be an Employee of the Company but continues, or simultaneously commences, services as a Non-Employee Director of the Company shall be deemed to have
had a termination of Continuous Service Status for purposes of the Plan. 

  
 24 

	 	(c)	 Notwithstanding the foregoing, neither the Company nor the Administrator shall have any obligation to take any
action to prevent the assessment of any additional tax or penalty on any Participant under Section 409A of the Code and neither the Company nor the Administrator will have any liability to any Participant for such tax or penalty.

  

	20.	 Beneficiaries. Unless stated otherwise in an Award Agreement, a Participant may designate one or
more beneficiaries with respect to an Award by timely filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. If no
beneficiary was designated or if no designated beneficiary survives the Participant, then, after a Participant’s death, any vested Award(s) shall be transferred or distributed to the Participant’s estate. 

 

	21.	 Expenses and Receipts. The expenses of the Plan shall be paid by the Company. Any proceeds
received by the Company in connection with any Award will be used for general corporate purposes. 

  

	22.	 Approval of Holders of Capital Stock. If required by the Applicable Laws, continuance of the Plan
shall be subject to approval by the holders of capital stock of the Company within twelve (12) months before or after the date the Plan is adopted by the Board or, to the extent required by Applicable Laws, any date the Plan is amended. Such
approval shall be obtained in the manner and to the degree required under the Applicable Laws. 

  

	23.	 Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the
Company of an Award to any Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Administrator, regardless of when the instrument, certificate, or letter evidencing the Award is
communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board or Committee consents, resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g.,
exercise price, vesting schedule or number of Shares) are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the preparation of the Award Agreement or related grant documentation, the
corporate records will control, and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documentation. 

 

	24.	 No Employment Rights. Neither the Plan nor any Award shall confer upon any Employee, Non-Employee Director or Consultant any right with respect to continuation of an employment or consulting relationship with the Company (or any Parent, Subsidiary or Affiliate thereof), nor shall it interfere in any
way with (i) such Employee’s, Non-Employee Director’s or Consultant’s right or the Company’s (or Parent’s, 

  
 25 

	 	
Subsidiary’s or Affiliate’s) right to terminate his or her employment or service relationship at any time, with or without Cause, or (ii) the Company’s right to increase or
decrease the compensation of the Participant from the rate in existence at the time of the grant of an Award. No payment with respect to any Awards 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. 

  

	25.	 No Right to Awards. No person shall have any claim or right to receive an Award hereunder. The
Administrator’s granting of an Award to a Participant at any time shall neither require the Administrator to grant an Award to such Participant, or to any other Participant or other person at any time, nor preclude the Administrator from making
subsequent grants to such Participant or any other Participant or other person. 

  

	26.	 Section 16. It is the intent of the Board that the Plan satisfy,
and be interpreted in a manner that satisfies, the applicable requirements of Rule 16b-3 so that Participants will be entitled to the benefit of Rule 16b-3, or any other
rule promulgated under Section 16 of the Exchange Act, and will not be subject to short-swing liability under Section 16 of the Exchange Act. Accordingly, if the operation of any provision of the Plan would conflict with the intent
expressed in this Section 26 such provision to the extent possible shall be interpreted and/or deemed amended so as to avoid such conflict. 

  

	27.	 Deferral of Awards. The Board may establish one or more programs under the Plan to permit
selected Participants the opportunity to elect to defer receipt of consideration upon exercise of an Award, satisfaction of performance criteria, or other event that absent the election would entitle the Participant to payment or receipt of Shares
or other consideration under an Award. The Board may establish the election procedures, the timing of such elections, the mechanisms for payments of, and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so
deferred, and such other terms, conditions, rules and procedures that the Board deems advisable for the administration of any such deferral program. 

  

	28.	 Unfunded Plan. The Plan shall be unfunded. Neither the Company nor any of its Subsidiaries,
Parents or Affiliates shall be required to establish any special or separate fund or to segregate any assets to assure the performance of its obligations under the Plan. 

 

	29.	 No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan,
including pursuant to any adjustment under Section 11. The Board shall determine whether cash, additional Awards or other securities or property shall be issued or paid in lieu of fractional Shares or whether any fractional Shares should be
rounded, forfeited or otherwise eliminated. 

  

	30.	 Disqualifying Dispositions. Any Participant who shall make a “disposition” (as defined
in Section 424 of the Code) of all or any portion of Shares acquired upon exercise of an Incentive Stock Option within two years from the date of grant of such Incentive Stock Option or within one year after the issuance of the Shares acquired
upon exercise of such Incentive Stock Option (a “Disqualifying Disposition”) shall be required to immediately advise the Company in writing as to the occurrence of the sale and the price realized upon the sale of such Shares.

  
 26 

	31.	 Documentation & Forfeiture Events. Each Award shall be
evidenced in an Award Agreement. Each Award Agreement may contain terms and conditions in addition to those set forth in the Plan. The Administrator may specify in an Award Agreement that the Participant’s rights, payments and benefits with
respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain events, in addition to applicable vesting conditions of an Award. Such events may include, without limitation, breach of non-competition, non-solicitation, confidentiality, or other restrictive covenants that are contained in the Award Agreement or otherwise applicable to the Participant, a
termination of the Participant’s service for Cause, or other conduct by the Participant that is detrimental to the business or reputation of the Company and/or its Affiliates. The Award Agreements authorized under the Plan may contain such
other provisions not inconsistent with the Plan, including, without limitation, restrictions upon the exercise of Awards, as the Board may deem advisable. 

  

	32.	 Severability. If all or any part of this Plan is declared by any court or governmental authority
to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any portion of this Plan not declared to be unlawful or invalid. Any Section or part of a Section so declared to be unlawful or invalid shall, if possible, be
construed in a manner that will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

 

	33.	 Governing Law. The Plan and the rights of all persons under the Plan shall be construed and
administered in accordance with the laws of the State of Delaware without regard to its conflict of law principles. 

  

	34.	 Headings. The headings in this Plan are included solely for convenience of reference and if there
is any conflict between such headings and the text of this Plan, the text shall control. 

  

	35.	 Term of Plan. The Plan shall come into existence upon its adoption by the Board and shall become
effective subject to the approval of the holders of capital stock of the Company as provided in Section 22 hereof. It shall continue in effect for a term of ten (10) years from its adoption by the Board unless sooner terminated under
Section 14 hereof. No Award shall be granted pursuant to the Plan after such termination date, but Awards theretofore granted may extend beyond that date. 

As adopted by the Board of Directors of Sotera Health Company on November 10, 2020. 

As approved by the sole stockholder of Sotera Health Company on November 10, 2020.
