To invoke a termination for Good Reason, the Executive shall provide written notice to the Company of the existence of one or more of the conditions described in clauses (1) through (7) within 90 days following the Executive’s knowledge of the initial existence of such condition or conditions, specifying in reasonable detail the conditions constituting Good Reason, and the Company DocuSign Envelope ID: A317C92E-D055-4D96-A471-0DADD4A22A28

- 6 - or the Affiliated Entity shall have thirty (30) days following receipt of such written notice (the “Cure Period”) during which it may remedy the condition. If the Company or the Affiliated Entity fails to remedy the condition constituting Good Reason during the applicable Cure Period, the Executive’s “separation from service” (within the meaning of Section 409A of the Code) must occur, if at all, no later than two years following the initial existence of such condition. The Executive’s mental or physical incapacity following the occurrence of an event described above in clauses (1) through (7) shall not affect the Executive’s ability to terminate employment for Good Reason and the Executive’s death following delivery of a Notice of Termination for Good Reason shall not affect the Executive’s estate’s entitlement to severance payments benefits provided hereunder upon a termination of employment for Good Reason. (d) Notice of Termination. Any termination of employment by the Company for Cause, or by the Executive for Good Reason, shall be communicated by Notice of Termination to the other party hereto delivered in accordance with Section 12(c). “Notice of Termination” means a written notice that (1) indicates the specific termination provision in this Agreement relied upon, (2) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated, and (3) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the Date of Termination. The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance that contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company, respectively, hereunder or preclude the Executive or the Company, respectively, from asserting such fact or circumstance in enforcing the Executive’s or the Company’s respective rights hereunder. (e) Date of Termination. “Date of Termination” means (1) if the Executive’s employment is terminated by the Company for Cause, or by the Executive for Good Reason, the date of receipt of the Notice of Termination or such later date specified in the Notice of Termination, as the case may be, which Date of Termination shall be not more than thirty (30) days after the later of the delivery of the Notice of Termination, and, in the case of a resignation by the Executive for Good Reason, shall not be earlier than the expiration of the Cure Period, unless the Company has notified the Executive that it is not going to cure, (2) if the Executive’s employment is terminated by the Company other than for Cause or by reason of death or Disability, the date on which the Company notifies the Executive of such termination, (3) if the Executive resigns without Good Reason, the date on which the Executive notifies the Company of such termination or such later date specified in the Notice of Termination, and (4) if the Executive’s employment is terminated by reason of death or Disability, the date of death of the Executive or the Disability Effective Date, as the case may be.

If, during the Protection Period, the Company terminates the Executive’s employment other than for Cause, death or Disability or the Executive terminates employment for Good Reason: (1) the Company shall pay to the Executive, in a lump sum, in cash, as soon as reasonably practicable following the Date of Termination, but in no event later than the twentieth (20th) day following the Date of Termination, the aggregate of the following amounts: DocuSign Envelope ID: A317C92E-D055-4D96-A471-0DADD4A22A28

Without limiting the generality of the foregoing, the Executive’s resignation under this Agreement with or without Good Reason, shall in no way affect the Executive’s ability to terminate employment by reason of the Executive’s “retirement” under, or to be eligible to receive benefits under, any compensation and benefits plans, programs or arrangements of the Company or the Affiliated Entities, including, without limitation, any retirement or pension plans or arrangements or substitute plans adopted by the Company, the Affiliated Entities or their respective successors, and any termination which otherwise qualifies as Good Reason under this Agreement shall be treated as such under this Agreement, even if it is also a “retirement” for purposes of any other plan or arrangement. DocuSign Envelope ID: A317C92E-D055-4D96-A471-0DADD4A22A28

- 10 - Section 6. No Duplication of Benefits; No Mitigation. Notwithstanding the foregoing, if the Executive receives payments and benefits pursuant to Section 4(a), the Executive shall not be entitled to any severance pay or benefits under any severance plan, program or policy of the Company and the Affiliated Entities, unless otherwise specifically provided therein in a specific reference to this Agreement. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, and such amounts shall not be reduced whether or not the Executive obtains other employment. Section 7. Full Settlement; Legal Fees. The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense, or other claim, right or action that the Company or an Affiliated Entity may have against the Executive or others. The Company agrees to pay as incurred (within ten (10) days following the Company’s receipt of an invoice from the Executive), at any time from the Change of Control through the Executive’s remaining lifetime (or, if longer, through the twentieth (20th) anniversary of the Change of Control) to the full extent permitted by law, all legal fees and expenses that the Executive may reasonably incur as a result of any contest by the Company, an Affiliated Entity, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive seeking to obtain or enforce any right or benefit provided by this Agreement). Section 8. Certain Reductions in Payments. (a) Anything in the Agreement to the contrary notwithstanding, if the Accounting Firm (as defined below) shall determine that receipt of all Payments (as defined below) would subject the Executive to the excise tax under Section 4999 of the Code, the Accounting Firm shall determine whether to reduce any of the Payments paid or payable pursuant to the Agreement (the “Agreement Payments”) so that the Parachute Value (as defined below) of all Payments, in the aggregate, equals the Safe Harbor Amount (as defined below). The Agreement Payments shall be so reduced only if the Accounting Firm determines that the Executive would have a greater Net After-Tax Receipt (as defined below) of aggregate Payments if the Agreement Payments were so reduced. If the Accounting Firm determines that the Executive would not have a greater Net After-Tax Receipt of aggregate Payments if the Agreement Payments were so reduced, the Executive shall receive all Agreement Payments to which the Executive is entitled hereunder. For purposes of all present-value determinations required to be made under this Section 8, the Company and the Executive elect to use the applicable federal rate that is in effect on the Effective Date pursuant to Treasury Regulations § 1- 280G, Q&A-32. (b) If the Accounting Firm determines that aggregate Agreement Payments should be reduced so that the Parachute Value of all Payments, in the aggregate, equals the Safe Harbor Amount, the Company shall promptly give the Executive notice to that effect and a copy of the detailed calculation thereof. All determinations made by the Accounting Firm under this Section 8 shall be binding upon the Company, the Affiliated Entities and the Executive and shall be made as soon as reasonably practicable and in no event later than 15 days following the Date of Termination. For purposes of reducing the Agreement Payments so that the Parachute Value of all Payments, in the aggregate, equals the Safe Harbor Amount, only amounts payable under the Agreement (and no other Payments) shall be reduced. The reduction of the amounts payable hereunder, if applicable, shall be DocuSign Envelope ID: A317C92E-D055-4D96-A471-0DADD4A22A28

- 11 - made by reducing the Agreement Payments that are parachute payments in the following order: (1) outplacement benefits under Section 4(a)(2), (2) any other non-cash and non-equity benefits payable to the Executive, and (3) any cash payments payable under Section 4(a)(1), beginning, in each case, with the payments or benefits that are to be paid or provided the farthest in time from the Date of Termination. All reasonable fees and expenses of the Accounting Firm shall be borne solely by the Company. (c) As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that amounts will have been paid or distributed by the Company to or for the benefit of the Executive pursuant to this Agreement that should not have been so paid or distributed (each, an “Overpayment”) or that additional amounts that will have not been paid or distributed by the Company to or for the benefit of the Executive pursuant to this Agreement could have been so paid or distributed (each, an “Underpayment”). In the event that the Accounting Firm, based upon the assertion of a deficiency by the Internal Revenue Service against the Company or the Executive that the Accounting Firm believes has a high probability of success determines that an Overpayment has been made, any such Overpayment paid or distributed by the Company to or for the benefit of the Executive shall be repaid by the Executive to the Company (as applicable) together with Interest; provided, however, that no such repayment shall be required if and to the extent such deemed repayment would not either reduce the amount on which the Executive is subject to tax under Section 1 and Section 4999 of the Code or generate a refund of such taxes.
