Re: Transition Agreement

Dear Jason:

This letter confirms that your employment with Amarin Corporation plc (together with its subsidiaries and any controlled affiliates, the "Company") will be ending. We appreciate your service and contributions and would like to make this transition as smooth as possible.

This letter sets forth the terms of a Transition Agreement (the “Agreement") between you and the Company under which you would remain employed by the Company and receive your current compensation and benefits (subject to the terms of any applicable benefits plan) and vest

in your outstanding, unvested equity awards between now and February 28,2023, unless your employment ends on an earlier date consistent with the terms of the Agreement. In addition, the below Agreement provides you the opportunity to receive the severance pay and benefits described in Section 4 below pursuant to the terms of the Amarin Corporation plc Executive Severance and Change of Control Plan effective as of January 28, 2021 (the "Plan"). As you

know, you are an "Eligible Executive" under the Plan, and provided that you satisfy the Conditions set forth in Section 3 below, the ending of your employment will be treated as a termination by the Company without Cause for purposes of the Plan. Accordingly, if you satisfy the Conditions, you will be eligible for the Severance Benefits under Section 3 of the Plan and as described in Section 4 below. The below Agreement is the "Release" and "Separation Agreement" described in the Plan.

With those understandings, the Agreement between you and the Company is as follows:

1.Transition Period

(a)If you enter into and comply with this Agreement, your employment with the Company will continue, along with the compensation, benefits and vesting described in Section l(c) below, until February 28, 2023, at which time it will end, unless you sooner resign or the Company sooner ends your employment for Cause (as defined in the Plan). The actual last day of your employment is referred to herein as the "Date of Termination." The time period between the date of this letter and the Date of Termination is referred to herein as the "Transition Period."

(b)At the commencement of the Transition Period, you will transition to the role of Senior Advisor. You agree to work professionally and cooperatively with the leadership team and your colleagues as requested during the

1

ACTIVE/120151144.1

 

Transition Period. You agree that Good Reason (as defined under the Plan) shall not apply during the Transition Period.

(c)You will continue to receive your current base salary and be eligible for benefits, subject to the terms of any applicable benefits plan, during the Transition Period. You will receive your full 2022 bonus in the amount of $313,000.00 in accordance with the bonus language in Section 6 of the Employment Agreement dated July 19, 2021 (the "Employment Agreement") and subsequent April 10, 2022 promotion letter. The bonus, will be paid no later than March 15, 2023. You will also continue to vest in your outstanding, unvested equity awards during the Transition Period, subject to the terms of the applicable stock option agreement or restricted stock unit agreement and equity incentive plan(s) (collectively, the "Equity Documents").

2.Ending of Employment

(a)Your employment with the Company will end on the Date of Termination, which will be no later than February 28, 2023. Regardless of whether you enter into this Agreement, the Company will provide you with the following "Accrued Obligations" in connection with the ending of your employment: (i) your base salary through the Date of Termination, (ii) an amount equal to the value of your accrued unused paid time off days through the Date of Termination, and (iii) the amount of any business expenses properly incurred by you on behalf of the Company prior to the Date of Termination and not yet reimbursed, if any. You agree that you will submit your final documented expense reimbursement statement reflecting all unreimbursed business expenses no later than 10 calendar days after the Date of Termination. You will not be eligible for any compensation or benefits after the Date of Termination except as set forth in this Agreement. For the avoidance of doubt, the Company's insider trading policy shall continue to be in effect during and after your employment, consistent with the terms of the policy.

(b)Your eligibility to participate in the Company's group health plans ceases on the last day of the month in which the Date of Termination occurs in accordance with the terms and conditions of those plans. You may elect to continue your existing health plan benefits under such plans in accordance with and subject to the law known as COBRA. You will be provided with information regarding COBRA under separate cover, and COBRA continuation coverage will be at your own cost, subject to Section 4(b) below if you satisfy the Conditions. Your eligibility to participate in the Company's other employee benefit plans and programs ceases on the Date of Termination in accordance with the terms and conditions of each of those benefit plans and programs.

(c)Consistent with the Equity Documents, you will cease vesting in your outstanding, unvested equity awards on the Date of Termination, subject to Section 4(c) below if you satisfy the Conditions. Any vested stock options must be exercised within the time period set forth in the Equity Documents.

ACTIVE/120151144.1

 

(d)You will be deemed to have resigned from all officer, trustee and board member positions that you hold with the Company or any of its respective subsidiaries and affiliates as of December 7, 2022. You agree to execute any documents requested by the Company or any of its respective subsidiaries and affiliates necessary to effectuate such resignations.

(e)You agree that you will promptly inform the Company of the commencement of any new employment prior to February 28, 2023 and that your employment with the Company, and the Transition Period, will end on the date immediately preceding the commencement of your new employment. However, if the CEO approves of your departure prior to February 28, 2023 to commence new employment. you will be paid through February 28, 2023 and, if you satisfy the Conditions, you will also be entitled to the Severance Benefits.

For the avoidance of doubt, if the Company terminates your employment for Cause, or if you fail to satisfy any of the Conditions, your employment will end and you will be entitled to the Accrued Obligations but will not be entitled to the Severance Benefits set forth in Section 4 or any other post-employment compensation or benefits from the Company.

4.Severance Benefits. If you satisfy the Conditions, then:

(a)the Company shall continue to pay you your current base salary for the twelve (12) month period following the Date of Termination (the "Salary Continuation Period"); and

(b)if you elect and remain eligible for COBRA continuation coverage, the Company shall continue your group health plan benefits to the extent authorized by and consistent with COBRA, with the cost of the regular premium for such benefits shared in the same relative proportion by the Company and you as in effect on the Date of Termination until the earlier of: (i) the end of the Salary Continuation Period, and (ii) the date that you become eligible for health benefits through another employer or otherwise become ineligible for COBRA; and

(c)the portion of your outstanding stock options, restricted stock units or other equity incentive awards (in each case, only to the extent subject to time-based vesting) that would have vested in the six (6) months following the Date of Termination will immediately accelerate and become fully exercisable or nonforfeitable as of the later of the Date of Termination and the effective date of this Agreement. The forfeiture of

3

ACTIVE/120151144.1

 

any unvested equity that is subject to acceleration will be delayed to the extent necessary to effectuate this provision and will not occur if the acceleration pursuant to this provision occurs.

The amounts payable under this Section 4 shall be paid out in substantially equal installments in accordance with the Company's payroll practice over the Salary Continuation Period commencing on the Company's first practicable payroll date following the Date of Termination; provided that the initial payment shall include a

catch-up payment to cover amounts retroactive to the day immediately following the Date of Termination.

(b)The parties intend that payments under this Agreement will be exempt from or comply with Section 409A of the Internal Revenue Code of 1986, as amended (the "Code"). To the extent that any provision of this Agreement is ambiguous as to its exemption from or compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder are exempt from or comply with Section 409A of the Code. The Company makes no representation or warranty and shall have no liability to you or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1, 409A 2(b)(2).

10.Acknowledgements and Representations You acknowledge and represent that, except as expressly provided in this Agreement, you have been paid all wages, bonuses, compensation, benefits and other amounts that any of the Releasees has ever owed to you, and you understand that you will not receive any additional compensation, severance or benefits after the Date of Termination, except as set forth in this Agreement.

(e)Relief. You agree that it would be difficult to measure any harm caused to the Company that might result from any breach by you of any of the Continuing Obligations. You further agree that money damages would be an inadequate remedy for any breach of the Continuing Obligations. Accordingly, you agree that if you breach, or propose to breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies it may have, to an injunction or other appropriate equitable relief to restrain any such breach, without showing or proving any actual damage to the Company and without the

(h)Waiver; Amendment. No waiver of any provision of this Agreement shall be effective unless made in writing and signed by the waiving party. The failure of a party to require the performance of any term or obligation of this Agreement, or the waiver by a party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. This Agreement may not be modified or amended except in a writing signed by both you and the CEO.

(i)Counterparts. This Agreement may be executed in separate counterparts. When both counterparts are signed, they shall be treated together as one and the same document. Electronic and pdf signatures shall be deemed to have the same legal effect as originals.
