4.Severance Benefits.

4.1Eligibility. Each Employee who qualifies as a Participant and who experiences a Qualifying Termination is eligible to receive Severance Benefits under the Plan.

4.2Qualifying Termination Payment. In the event that a Participant experiences a Qualifying Termination (other than a CIC Termination), then, subject to the Participant’s execution and, to the extent applicable, non-revocation of a Release in accordance with Section 4.4 hereof, and subject to any additional requirements specified in the Plan, the Company shall pay or provide to the Participant the following Severance Benefits:

(a)Cash Severance Payment. The Company shall pay to the Participant a lump-sum cash payment in an amount equal to the amount determined in accordance with Exhibit A attached hereto. Subject to Section 6.2 hereof, the Cash Severance (as set forth on Exhibit A) shall be paid to the Participant within 60 days following the Date of Termination.

(b)COBRA. Subject to the requirements of the Code, if the Participant properly elects health care continuation coverage under the Company’s group health plans pursuant to COBRA, to the extent that the Participant is eligible to do so, then the Company shall directly pay or, at its election, reimburse the Participant for the COBRA premiums for the Participant and the Participant’s covered dependents (in an amount determined based on the same benefit levels as would have applied if the Participant’s employment had not been terminated based on the Participant’s elections in effect on the Date of Termination) until the earlier of the end of the month during which the Participant’s COBRA Period, determined in accordance with Exhibit A attached hereto, ends or the date the Participant becomes eligible for healthcare coverage under a subsequent employer’s health plan (the “COBRA Premium Payment”); provided, however, that the Company shall not subsidize COBRA premiums for any health flexible savings accounts or health reimbursement arrangements. Notwithstanding the foregoing, (i) if any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the period of continuation coverage to be, exempt from the application of Code Section 409A under Treasury Regulation Section 1.409A-1(a)(5), or (ii) the Company is otherwise unable to continue to cover the Participant under its group health plans without penalty under applicable law (including without limitation, Section 2716 of the Public Health Service Act), then, in either case, an amount equal to each remaining Company reimbursement shall thereafter be paid to the Participant in substantially equal monthly installments over the COBRA Period (or the remaining portion thereof).

(c)Certain Exceptions. Notwithstanding anything to the contrary contained herein, with respect to each Participant set forth on Exhibit C attached hereto, if the Participant experiences a Qualifying Termination (other than a CIC Termination) as defined on Exhibit C, then such Participant shall be eligible to receive the payments and benefits set forth on Exhibit C rather than the payments and benefits described in Sections 4.2(a) and (b), subject to the terms and conditions set forth in Exhibit C.

4.3CIC Termination Payment.

(a)In the event that a Participant experiences a CIC Termination, then, subject to the Participant’s execution and, to the extent applicable, non-revocation of a Release in accordance with Section 4.4 hereof, and subject to any additional requirements specified in the Plan, (i) the Company shall pay or provide to the Participant, as applicable, the Severance Benefits set forth in Sections 4.2(a) and (b) hereof; provided, however, that the amount of the Cash Severance and the COBRA Period shall be determined in accordance with Exhibit B attached hereto (instead of in accordance with Exhibit A) and any Cash Severance set forth in Exhibit B that exceeds the Cash Severance the Participant’s would receive pursuant to Exhibit A will be paid in a lump-sum on the later of the date of the Change in

Control and the 60th day following the Date of Termination, and (ii) except as otherwise set forth in an individual award agreement, each outstanding Equity Award held by the Participant as of his or her Date of Termination shall be determined in accordance with Exhibit B attached hereto.

(b)Notwithstanding anything to the contrary contained herein, with respect to each Participant set forth on Exhibit D attached hereto, if the Participant experiences a CIC Termination as defined on Exhibit D, then the Participant shall be eligible to receive the payments and benefits set forth on Exhibit D rather than the payments and benefits described in Section 4.3(a), subject to the terms and conditions set forth in Exhibit D.

4.4Release. Notwithstanding anything herein to the contrary, no Participant shall be eligible or entitled to receive or retain any Severance Benefits under the Plan unless he or she executes a general release of claims in a form prescribed by the Company (the “Release”) within 21 days (or 45 days if necessary to comply with applicable law) after the Date of Termination and, if he or she is entitled to a seven day post-signing revocation period under applicable law, does not revoke such Release during such seven day period. For the avoidance of doubt, with respect to each Participant set forth on Exhibit C and Exhibit D attached hereto, “Release” shall be as defined in Exhibit C and Exhibit D, as applicable.

4.5 Reduction for other Severance Payments or Notice Period. The amount of Severance Benefits to which a Participant is otherwise entitled under the Plan shall be reduced by any other severance benefits payable to the Participant under any other Company plan, program, agreement, statutorily required severance, or legally required notice period for which the Company, in its discretion, provides pay in lieu of notice.

5.Limitations. Notwithstanding any provision of the Plan to the contrary, if a Participant’s status as an Employee is terminated for any reason other than due to a Qualifying Termination, the Participant shall not be entitled to receive any Severance Benefits under the Plan, and the Company shall not have any obligation to such Participant under the Plan.

6.Section 409A.

6.1General. To the extent applicable, the Plan shall be interpreted and applied consistent and in accordance with Code Section 409A and Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of the Plan to the contrary, to the extent that the Administrator determines that any payments or benefits under the Plan may not be either compliant with or exempt from Code Section 409A and related Department of Treasury guidance, the Administrator may in its sole discretion adopt such amendments to the Plan or take such other actions that the Administrator determines are necessary or appropriate to (a) exempt the compensation and benefits payable under the Plan from Code Section 409A and/or preserve the intended tax treatment of such compensation and benefits, or (b) comply with the requirements of Code Section 409A and related Department of Treasury guidance; provided, however, that this Section 6.1 shall not create any obligation on the part of the Administrator to adopt any such amendment or take any other action, nor shall the Company have any liability for failing to do so.

6.2Potential Six-Month Delay. Notwithstanding anything to the contrary in the Plan, no amounts shall be paid to any Participant under the Plan during the six-month period following such Participant’s “separation from service” (within the meaning of Code Section 409A(a)(2)(A)(i) and Treasury Regulation Section 1.409A-1(h)) to the extent that the Administrator determines that paying such amounts at the time or times indicated in the Plan would result in a prohibited distribution under

Code Section 409A(a)(2)(B)(i). If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six-month period (or such earlier date upon which such amount can be paid under Code Section 409A without resulting in a prohibited distribution, including as a result of the Participant’s death), the Participant shall receive payment of a lump-sum amount equal to the cumulative amount that would have otherwise been payable to the Participant during such six-month period without interest thereon.

6.3Separation from Service. A termination of employment shall not be deemed to have occurred for purposes of any provision of the Plan providing for the payment of any amounts or benefits that constitute “nonqualified deferred compensation” under Code Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of the Plan, references to a “termination,” “termination of employment” or like terms shall mean “separation from service”.

6.4Reimbursements. To the extent that any payments or reimbursements provided to a Participant under the Plan are deemed to constitute compensation to the Participant to which Treasury Regulation Section 1.409A-3(i)(1)(iv) would apply, such amounts shall be paid or reimbursed reasonably promptly, but not later than December 31st of the year following the year in which the expense was incurred. The amount of any such payments eligible for reimbursement in one year shall not affect the payments or expenses that are eligible for payment or reimbursement in any other taxable year, and the Participant’s right to such payments or reimbursement of any such expenses shall not be subject to liquidation or exchange for any other benefit.

6.5Installments. For purposes of applying the provisions of Code Section 409A to the Plan, each separately identified amount to which a Participant is entitled under the Plan shall be treated as a separate payment. In addition, to the extent permissible under Code Section 409A, the right to receive any installment payments under the Plan shall be treated as a right to receive a series of separate payments and, accordingly, each such installment payment shall at all times be considered a separate and distinct payment as permitted under Treasury Regulation Section 1.409A-2(b)(2)(iii). Whenever a payment under the Plan specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

7.Limitation on Payments.

7.1Best Pay Cap. Notwithstanding any other provision of the Plan, in the event that any payment or benefit received or to be received by a Participant (including any payment or benefit received in connection with a termination of the Participant’s employment, whether pursuant to the terms of the Plan or any other plan, arrangement or agreement) (all such payments and benefits, including the Severance Benefits, being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Code Section 4999 (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Code Section 280G in such other plan, arrangement or agreement, the Cash Severance benefits under the Plan shall first be reduced, and any noncash severance payments hereunder shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (a) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (b) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of

Excise Tax to which the Participant would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments).

7.2Certain Exclusions. For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (a) no portion of the Total Payments, the receipt or retention of which the Participant has waived at such time and in such manner so as not to constitute a “payment” within the meaning of Code Section 280G(b), will be taken into account; (b) no portion of the Total Payments will be taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the Company, does not constitute a “parachute payment” within the meaning of Code Section 280G(b)(2) (including by reason of Code Section 280G(b)(4)(A)) and, in calculating the Excise Tax, no portion of such Total Payments will be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Code Section 280G(b)(4)(B), in excess of the “base amount” (as defined in Code Section 280G(b)(3)) allocable to such reasonable compensation; and (c) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in accordance with the principles of Code Sections 280G(d)(3) and (4).

8.No Mitigation. No Participant shall be required to seek other employment or attempt in any way to reduce or mitigate any Severance Benefits payable under the Plan and the amount of any such Severance Benefits shall not be reduced by any other compensation paid or provided to any Participant following such Participant’s termination of service.

9.Successors.

9.1Company Successors. The Plan shall inure to the benefit of and shall be binding upon the Company and its successors and assigns. Any successor (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets shall assume and agree to perform the obligations of the Company under the Plan.

9.2Participant Successors. The Plan shall inure to the benefit of and be enforceable by each Participant’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees, legatees or other beneficiaries. If a Participant dies while any amount remains payable to such Participant hereunder, all such amounts shall be paid in accordance with the terms of the Plan to the executors, personal representatives or administrators of such Participant’s estate.

10.Notices. All communications relating to matters arising under the Plan shall be in writing and shall be deemed to have been duly given when hand delivered, faxed, emailed or mailed by reputable overnight carrier or United States certified mail, return receipt requested, addressed, if to a Participant, to the address on file with the Company or to such other address as the Participant may have furnished to the Company in writing in accordance herewith and, if to the Company, to such address as may be specified from time to time by the Administrator, except that notice of change of address shall be effective only upon actual receipt.

11.Claims Procedure; Arbitration.

11.1Claims. Generally, Participants are not required to present a formal claim in order to receive benefits under the Plan. If, however, any person believes that benefits are being denied

improperly, that the Plan is not being operated properly, or that their legal rights are being violated with respect to the Plan (the “Claimant”), the Claimant must file a formal claim, in writing, with the Administrator. This requirement applies to all claims that any Claimant has with respect to the Plan, except to the extent the Administrator determines, in its sole discretion, that it does not have the power to grant all relief reasonably being sought by the Claimant. A formal claim must be filed within 90 days after the date the Claimant first knew or should have known of the facts on which the claim is based, unless the Administrator consents otherwise in writing. The Administrator shall provide a Claimant, on request, with a copy of the claims procedures established under Section 11.2 hereof.

11.2Claims Procedure. The Administrator has adopted procedures for considering claims (which are set forth in Exhibit E attached hereto), which it may amend or modify from time to time, as it sees fit. These procedures shall comply with all applicable legal requirements. These procedures may provide that final and binding arbitration shall be the ultimate means of contesting a denied claim (even if the Administrator or its delegates have failed to follow the prescribed procedures with respect to the claim). The right to receive benefits under the Plan is contingent on a Claimant using the prescribed claims and appeal procedures to resolve any claim.

12.Covenants.

12.1Restrictive Covenants. A Participant’s right to receive and/or retain the Severance Benefits payable under this Plan is conditioned upon and subject to the Participant’s continued compliance with any restrictive covenants (e.g., confidentiality, non-solicitation, non-competition, non-disparagement) contained in any other written agreement between the Participant and the Company, as in effect on the date of the Participant’s Qualifying Termination.

12.2Return of Property. A Participant’s right to receive and/or retain the Severance Benefits payable under the Plan is conditioned upon the Participant’s return to the Company of all Company documents (and all copies thereof) and other Company property (in each case, whether physical, electronic or otherwise) in the Participant’s possession or control.

13.Miscellaneous.

13.1Entire Plan; Relation to Other Agreements. The Plan, together with any Participation Notice issued in connection with the Plan, contains the entire understanding of the parties relating to the subject matter hereof and supersedes any prior agreement, arrangement and understanding between any Participant, on the one hand, and the Company and/or any subsidiary, on the other hand, with respect to the subject matter hereof. Severance Benefits payable under the Plan are not intended to duplicate any other severance benefits payable to a Participant by the Company. By participating in the Plan and accepting the Severance Benefits hereunder, the Participant acknowledges and agrees that any prior agreement, arrangement and understanding between any Participant, on the one hand, and the Company and/or any subsidiary, on the other hand, with respect to the subject matter hereof is hereby revoked and ineffective with respect to the Participant.

13.2Participation Notices. The Administrator shall have the authority, in its sole discretion, to select Employees to participate in the Plan and to provide written notice to any such Employee that he or she is a Participant in, and eligible to receive Severance Benefits under, the Plan (a “Participation Notice”) at or any time prior to his or her termination of employment.

13.3No Right to Continued Service. Nothing contained in the Plan shall (a) confer upon any Participant any right to continue as an employee of the Company or any subsidiary, (b) constitute any

contract of employment or agreement to continue employment for any particular period, or (c) interfere in any way with the right of the Company to terminate a service relationship with any Participant, with or without Cause.

13.4Termination and Amendment of Plan. Prior to the consummation of a Change in Control, the Plan may be amended or terminated by the Administrator at any time and from time to time, in its sole discretion; provided, however, that Exhibit C and Exhibit D attached hereto may not be amended or terminated with respect to a Participant set forth on the applicable exhibit without the written consent of such Participant. For a period of one year from and after the consummation of a Change in Control, the Plan may not be amended, modified, suspended or terminated except with the express written consent of each Participant who would be adversely affected by any such amendment, modification, suspension or termination. After the expiration of such one-year period, and subject to Section 2 hereof, the Plan may again be amended or terminated by the Administrator at any time and from time to time, in its sole discretion (provided, that no such amendment or termination shall adversely affect the rights of any Participant who has experienced a Qualifying Termination on or prior to the date of such amendment or termination).

13.5Survival. Section 7 (Limitation on Payments), Section 11 (Claims Procedure; Arbitration) and Section 12 (Covenants) hereof shall survive the termination or expiration of the Plan and shall continue in effect.

13.6Severance Benefit Obligations. Notwithstanding anything contained herein, Severance Benefits paid or provided under the Plan may be paid or provided by the Company or any subsidiary employer, as applicable.

13.7Withholding. The Company shall have the authority and the right to deduct and withhold an amount sufficient to satisfy federal, state, local and foreign taxes required by law to be withheld with respect to any Severance Benefits payable under the Plan.

13.8Benefits Not Assignable. Except as otherwise provided herein or by law, no right or interest of any Participant under the Plan shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation by execution, levy, garnishment, attachment, pledge or in any manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of any Participant under the Plan shall be liable for, or subject to, any obligation or liability of such Participant. When a payment is due under the Plan to a Participant who is unable to care for his or her affairs, payment may be made directly to his or her legal guardian or personal representative.

13.9Applicable Law. The Plan is intended to be an unfunded “top hat” pension plan within the meaning of U.S. Department of Labor Regulation Section 2520.104-23 and shall be interpreted, administered, and enforced as such in accordance with ERISA. To the extent that state law is applicable, the statutes and common law of the State of Delaware, excluding any that mandate the use of another jurisdiction’s laws, will apply.

13.10Validity. The invalidity or unenforceability of any provision of the Plan shall not affect the validity or enforceability of any other provision of the Plan, which shall remain in full force and effect.

13.11Captions. The captions contained in the Plan are for convenience only and shall have no bearing on the meaning, construction or interpretation of the Plan’s provisions.

13.12Expenses. The expenses of administering the Plan shall be borne by the Company or its successor, as applicable.

13.13Unfunded Plan. The Plan shall be maintained in a manner to be considered “unfunded” for purposes of ERISA. The Company shall be required to make payments only as benefits become due and payable. No person shall have any right, other than the right of an unsecured general creditor against the Company, with respect to the benefits payable hereunder, or which may be payable hereunder, to any Participant, surviving spouse or beneficiary hereunder. If the Company, acting in its sole discretion, establishes a reserve or other fund associated with the Plan, no person shall have any right to or interest in any specific amount or asset of such reserve or fund by reason of amounts which may be payable to such person under the Plan, nor shall such person have any right to receive any payment under the Plan except as and to the extent expressly provided in the Plan. The assets in any such reserve or fund shall be part of the general assets of the Company, subject to the control of the Company.

In the event that Helmy Eltoukhy or AmirAli Talasaz (each, a “Participant” for purposes of this Exhibit C and a “Participant” for purposes of the Plan) experiences a Qualifying Termination (other than a CIC Termination), then, subject to the Participant’s execution and, to the extent applicable, non-revocation of a Release in accordance with this Exhibit C, and subject to any additional requirements specified in the Plan, the Company shall pay or provide to such Participant the following payments and benefits, as applicable, which shall constitute “Severance Benefits” for purposes of the Plan:

(a)The Participant’s Annual RSU Award (as defined in the Letter Agreement) outstanding on the Date of Termination will vest and accelerate in full on the effectiveness of the Release. In addition, the Company shall pay to the Participant a lump-sum cash payment in an amount equal to the dollar-denominated value of the Annual RSU Award Participant is entitled to receive with respect to the calendar year in which the Date of Termination occurs (the “Annual RSU Award Value”), multiplied by a fraction, the numerator of which is the number of days between (and including) January 1 and the Date of Termination and the denominator of which is 365 (the “Additional Cash Severance”). The Additional Cash Severance shall be paid to the Participant within 60 days following the Date of Termination in accordance with Section 4.2(a) of the Plan. Notwithstanding the generality of the foregoing, (i) if the Participant is receiving an annual base salary with respect to such year in addition to such Annual RSU Award, then the Company also shall pay to the Participant the Cash Salary Severance in an amount equal to 12 months Base Compensation in accordance with Section 4.2(a) of the Plan, (ii) if the Participant is receiving an annual base salary with respect to such year in lieu of such Annual RSU Award, then the Company instead shall pay to the Participant the Cash Salary Severance in an amount equal to 12 months Base Compensation in accordance with Section 4.2(a) of the Plan and (iii) if the Participant is not receiving an annual salary with respect to such year in lieu of such Annual RSU Award, and has not been granted an Annual RSU Award as of the Date of Termination with respect to the calendar year in which the Date of Termination occurs, then the Additional Cash Severance amount shall be equal to the Annual RSU Award Value.

(b)A number of performance-based restricted stock units (“PSUs”) subject to the Participant’s Annual PSU Award (as defined in the Letter Agreement) will vest and accelerate equal to the target number of PSUs subject to such award, prorated to reflect the period of time during the performance period that the Participant was employed with the Company through the Date of Termination (such number of PSUs, the “Prorated PSUs”) on the effectiveness of the Release. Notwithstanding the generality of the foregoing, if the Participant either (i) has not been granted an Annual PSU Award as of the Date of Termination with respect to the calendar year in which the Date of Termination occurs or (ii) is instead eligible to receive an annual cash bonus with respect to such year in lieu of such Annual PSU Award, in either case, then the Company instead shall pay to the Participant the Pro-Rata Target Incentive Compensation in accordance with Section 4.2(a) of the Plan; provided, however, that in calculating such amount in the case of clause (i) above, the Participant’s Target Incentive Compensation shall equal the target dollar-denominated value of the Annual PSU Award Participant is entitled to be granted with respect to the calendar year in which the Date of Termination occurs. For the avoidance of doubt, if the Date of Termination occurs after the end of the applicable performance period and prior to the date any Earned PSUs (as defined in the applicable award agreement) vest, then any Earned PSUs that remain unvested shall vest on the effectiveness of the Release.

(c)Except as otherwise set forth in the applicable award agreement and subject to Exhibit D, any Time-Based Equity Award that is not an Annual RSU Award held by the Participant as of the Date of Termination shall vest and become exercisable (as applicable), upon the effectiveness of the Release, as to the portion of the Time-Based Equity Award that would have vested (and become exercisable) (as applicable) over the one-year period following such Date of Termination, had Participant remained in continuous service during such one-year period.

(d)Except as otherwise set forth in the applicable award agreement and subject to Exhibit D, with respect to each outstanding Performance-Based Equity Award held by the Participant as of the Date of Termination that is not an Annual PSU Award, (i) the service-based condition with respect to such award shall be deemed satisfied through the one-year period following the Date of Termination and (ii) if, following the application of such deemed satisfaction of the service-based condition, the Participant satisfies the requirement to remain employed through the applicable vesting date of the award, then such award shall vest and become exercisable (as applicable), upon the effectiveness of the Release, as to the target number of shares subject to such award. For clarity, and except as otherwise provided in Exhibit D, if, following the application of such deemed satisfaction of the service-based condition, the Participant does not satisfy the requirement to remain employed through the applicable vest date of such award, then such award shall not vest but instead shall be forfeited.

(e)The Participant shall be entitled to the COBRA Premium Payment described in Section 4.2(b) of the Plan and Exhibit A.

For the avoidance of doubt, with respect to a Qualifying Termination that occurs three months prior to the date of a Change in Control, the remaining unvested portion of any Time-Based Equity Award that is not an Annual RSU Award or Performance-Based Equity Award that is not an Annual PSU Award shall remain outstanding and eligible to vest as set forth on Exhibit D. If a Change in Control does not occur within the three-month period after a Qualifying Termination, then the remaining unvested portion of any Time-Based Equity Award that is not an Annual RSU Award or Performance-Based Equity Award that is not an Annual PSU Award will be forfeited on the three-month anniversary of the Date of Termination.

Notwithstanding anything to the contrary contained in Section 4.4, the Release shall be delivered to the Participant within five business days following the Date of Termination, and Participant shall have 21 days thereafter (or 45 days, if necessary to comply with applicable law) to execute and deliver the Release to the Company. The Company may update the Release to the extent necessary to reflect changes in law but without increasing the scope of the Release. In no event shall any additional covenant or obligation on the part of the Participant be added to the Release.

Section (c) above is intended by the parties to be the final expression of their agreement with respect to the treatment of Time-Based Equity Awards in connection with a Qualifying Termination (other than a CIC Termination) and supersedes all prior understandings and agreements, whether written or oral, including, that certain letter agreement by and between Participant and the Company, dated March 4, 2019 (the “2019 Letter”).

“Good Reason” shall mean the occurrence of any one or more of the following events without Participant’s prior written consent, unless the Company fully corrects the circumstances constituting Good Reason (provided such circumstances are capable of correction) as provided below:

(i)a material diminution in Participant’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities, including (without limitation) Participant’s ceasing to be Co-Chief Executive Officer, or the sole Chief Executive Officer, of a public company following the occurrence of a Change in Control, but excluding for this purpose any isolated, insubstantial or inadvertent actions not taken in bad faith and which are remedied by the Company promptly after receipt of notice thereof given by Participant;

(ii)a change in the geographic location at which Participant performs his principal duties for the Company to a new location that is more than 30 miles from the location at which Participant performs his principal duties for the Company as of March 18, 2024; or

(iii)the Company’s material breach of a material written agreement between the Company and Participant (including this Plan).

Notwithstanding the foregoing, Participant will not be deemed to have resigned for Good Reason unless (1) Participant provides the Company with written notice setting forth in reasonable detail the facts and circumstances claimed by Participant to constitute Good Reason within 90 days after the date of the occurrence of any event that Participant knows or should reasonably have known to constitute Good Reason, (2) the Company fails to cure such acts or omissions within 30 days following its receipt of such notice, and (3) the effective date of Participant’s termination for Good Reason occurs no later than 60 days after the expiration of the Company’s cure period.

(a)The Company shall pay to the Participant an additional amount in cash equal to the Annual RSU Award Value Participant is entitled to receive with respect to the calendar year in which the Date of Termination occurs; provided, however, that (i) if Participant is instead receiving an annual base salary with respect to such year in lieu of such Annual RSU Award, then the Company instead shall pay to the Participant an additional amount equal to 100% of Participant’s Base Compensation for such calendar year and (ii) if the Participant is receiving an annual base salary with respect to such year in addition to such Annual RSU Award, then the Company also shall pay to the Participant an additional amount equal to 100% of Participant’s Base Compensation for such calendar year. The applicable amount shall be paid in a lump-sum on the later of the 60th day following the Date of Termination and the date of the Change in Control.

(b)A number of PSUs subject to Participant’s Annual PSU Award outstanding on the Date of Termination equal to the difference between the target number of PSUs subject to such award and the number of Prorated PSUs shall vest in full upon the later of the effectiveness of the Release and the date of the Change in Control. Notwithstanding the generality of the foregoing, if the Participant either (i) has not been granted an Annual PSU Award as of the Date of Termination with respect to the calendar year in which the Date of Termination occurs or (ii) is instead eligible to receive an annual cash bonus with respect to such year in lieu of such Annual PSU Award, in either case, then the Company instead shall pay to the Participant, on the later of the effectiveness of the Release and the date of the Change in Control, an amount in cash equal to the difference between the Target Incentive Compensation and the Pro-Rata Target Incentive Compensation; provided, however, that in calculating such amount in the case of clause (i) above, the Participant’s Target Incentive Compensation shall equal the target dollar-denominated value of the Annual PSU Award Participant is entitled to be granted with respect to the calendar year in which the Date of Termination occurs.

Notwithstanding anything to the contrary contained in Section 4.4, the Release shall be delivered to the Participant within five business days following the Date of Termination, and Participant shall have 21 days thereafter (or 45 days, if necessary to comply with applicable law) to execute and deliver the Release to the Company.

In the event that the Administrator determines that such an extension is required, written notice of the extension will be furnished to the Claimant before the end of the initial 90 day review period. The extension will not exceed a period of 90 days from the end of the initial 90 day period, and the extension notice will indicate the special circumstances requiring such extension of time and the date by which the Administrator expects to render the benefit decision.

A determination on the appeal by the Administrator will be made within a reasonable period of time, but not later than 60 days after receipt of an appeal request, unless the Administrator determines that an extension of time for processing is required.

The extension will not exceed a period of 60 days from the end of the initial 60-day period, and the extension notice will indicate the special circumstances requiring such extension of time and the date by which the Administrator expects to render the determination on appeal.

Any such judicial proceeding must be filed by the earlier of: (a) one year after the final adverse benefit determination or (b) one year after the Participant or other Claimant commenced payment of the Plan benefits at issue in the judicial proceeding.

Section 1.8.    Administrator’s Decision is Binding. Benefits under the Plan shall be paid only if the Administrator decides in its sole discretion that a Claimant is entitled to them. In determining claims for benefits, the Administrator has the authority to interpret the Plan, to resolve ambiguities, to make factual determinations, and to resolve questions relating to eligibility for and amount of benefits. Subject to

applicable law, any decision made in accordance with the above claims procedures is final and binding on all parties and shall be given the maximum possible deference allowed by law. A misstatement or other mistake of fact shall be corrected when it becomes known and the Administrator shall make such adjustment on account thereof as it considers equitable and practicable.
