Elanco Executive Severance Pay Plan and Summary

Introduction

The Elanco Executive Severance Pay Plan and Summary ("Plan") effective as of ________, 2020, defines those circumstances under which Elanco US Inc. and Lohmann Animal Health International, Inc. (collectively, "Elanco" or the "Company") may provide severance benefits to you in the event your employment with Elanco is terminated under certain circumstances. The Plan supersedes any and all prior severance plans or programs under which you may have been previously covered, except as otherwise noted herein.

This document serves as both the formal plan document and the summary for the Plan. This document explains eligibility, exclusions, benefits and administration. Any questions about the Plan or its operation should be directed to your Human Resources Representative.

The Plan is part of the Elanco US Inc. Health and Welfare Plan, which was established to provide medical, dental, extended disability, life insurance, holiday, vacation, and other benefits for eligible employees. It is the intention of Elanco that the Plan be a welfare benefit plan subject to the requirements of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). The Plan is not intended to be an "employee pension benefit plan" or "pension plan" as those terms are defined in Section 3(2) of ERISA. Rather, the Plan is intended to constitute the type of arrangement identified as a "severance pay arrangement" within the meaning of Section 3(2)(B)(i) of ERISA, as further elaborated by regulations promulgated by the Secretary of Labor at Title 29, Code of Federal Regulations § 2510.3-2(b). The Plan is intended to be exempt from the reporting and disclosure requirements of Part I of Title I of ERISA, whereby benefits are provided to a select group of management or highly compensated employees, as provided under Title 29, Code of Federal Regulations § 2520-104-24(c). The benefits paid by the Plan are not intended to constitute deferred compensation and, as such, it is intended that the Plan be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”).

Elanco supports compliance with federal law in all respects and will not take any action against employees because they have exercised their rights under the law. If you have any complaints of discrimination or questions or concerns about the requirements to receive severance benefits from Elanco, you are encouraged to contact a representative of Elanco’s Human Resources Department or the Equal Employment Opportunity Commission at 101 West Ohio Street, Suite 1900, Indianapolis IN 46204- 4203, (317) 226-7212 or (317) 226-5162 (TTY). An employee has the right, and is encouraged to exercise that right, to report allegations of employment discrimination in the workplace.

Section 1 – Purpose

The purpose of this Plan is to define those circumstances under which Elanco may pay you severance benefits. Elanco and this Plan do not provide severance benefits to you as a matter of right. Whether or not severance benefits will be paid to you depends on you satisfying all conditions set forth in the Plan necessary for you to be eligible for severance benefits, including a determination by Elanco, in its sole and absolute discretion, of whether to offer you any severance benefits hereunder.

Section 2 – Who Is Eligible

Employees of Elanco who are classified by Elanco as an M4_VP - M7 global job level (VP, SVP, EVP, CEO), including executive officers (as defined in Rule 3b-7 under the Exchange Act), or any successor classifications shall be eligible to participate in the Plan and shall be considered an “Eligible Employee” for all purposes hereunder, provided such Eligible Employees meet all of the requirements set forth herein, as determined by Elanco on a case by case basis, and further provided, that the individual does not satisfy and will not satisfy the conditions to receive severance benefits under any other arrangement or agreement between the individual and Elanco. Elanco reserves the right, in its discretion, to cover any

- 1 -

additional positions or individuals under the Plan. Your eligibility to receive a benefit depends on the circumstances surrounding your separation from service with Elanco, and the mandatory requirement that you execute (and do not timely revoke) a written severance agreement and release in a form and upon such terms as provided to you by Elanco, which shall include, but not be limited to, a waiver and release of claims, nondisclosure and non-solicitation provisions ("Severance Agreement and Release"). Notwithstanding anything herein to the contrary, in all cases, the decision to offer severance benefits is within the sole and absolute discretion of Elanco.

Section 3 – Under What Circumstances Will Benefits Be Paid

Subject to the discretion of Elanco, you may receive a severance benefit under the Plan if you are an Eligible Employee (as described in Section 2) upon your separation from service with Elanco for one of the following reasons, and provided you execute (and do not timely revoke) a written Severance Agreement and Release provided to you by Elanco:

• You are discharged, or you resign in lieu of discharge (as determined by the Company in its sole discretion), and your discharge is not due to misconduct, violation of Company possession of firearms policy, violation of Company alcohol, drug or gambling policies, insubordination, or an unscheduled absence of three consecutive workdays without notice, other than due to illness or disability.

• You resign due to disability (as defined in the Company’s long-term disability insurance plan), and you are ineligible for disability benefits under the Company’s long-term disability insurance plan because you did not satisfy a length-of-service requirement or your disability constituted a prior condition under such long-term disability insurance plan.

•Under certain circumstances, when the office or facility in which you work closes.

•Any other reason the Company determines, in its sole discretion, it is appropriate to be entitled to the payment of a severance benefit.

The Plan Administrator or its delegate, subject to the provisions of the Plan, may adopt such rules and regulations as it deems necessary to carry out the provisions of the Plan.

The Plan Administrator or its delegate shall have the power of full and final determination as to all issues concerning eligibility for benefits under the Plan and interpretation of the Plan and determination of

Notwithstanding anything in this Plan to the contrary, if, at the time of your separation from service with Elanco, you are a “specified employee” (as such term is defined in Section 409A), and the deferral of the commencement of any payment otherwise payable hereunder as a result of such separation from service is necessary to prevent any accelerated or additional tax under Section 409A, then Elanco, as applicable, will defer the payment or commencement of any such payments (without any reduction in such payments ultimately paid or provided) until the date six (6) months following your separation from service (or the earliest date as is permitted under Section 409A), or such payment shall be restructured, to the extent possible, in a manner, as determined by the Plan Administrator, that does not cause such an accelerated or additional tax.

Section 16 - Benefits as Consideration for Waivers, Covenants and Releases

The benefits provided under the Plan will constitute consideration for the release you are required to provide to the Company relating to prior employment by the Company. The benefits will also constitute consideration for any waiver by you, whether full or partial, and whether absolute or conditional, of any rights, claims, entitlement to relief or damages, or entitlement to seek imposition upon the Company of penalties, in connection with any contract, express or implied, or under any statute, regulation, rule, order,

- 6 -

The Plan Administrator will prepare and will file as required by law or regulation all reports, forms, documents and other items required by ERISA, the Code, and every other relevant statute, each as amended, and all regulations thereunder (except Company, as payer of the benefits, will prepare and distribute to the proper recipients all forms relating to withholding of income or wage taxes, Social Security contributions, and other amounts which may be similarly reportable).
