Mr. Michael W. Kalb 
 24 Lucille Lane 

Dix Hills, New York 11746 
 Dear Mike: 

On behalf of Amarin Corporation plc (the “Company”), I am pleased to offer you employment in the role the Company’s Senior Vice
President and Chief Financial Officer under the following terms. 
 1. Position: Senior Vice President and Chief Financial Officer is
a full-time position as an officer of the Company. It is understood and agreed that, while you render services to the Company, you will not engage in any other employment, consulting or other business activities (whether full-time or part-time).
Notwithstanding the foregoing, you may engage in religious, charitable, or other community activities so long as such services or activities do not interfere or conflict with your obligations to the Company. In addition to your role as Senior Vice
President of the Company, you acknowledge and agree that you may be required, without additional compensation, to perform duties for certain affiliated entities of the Company, including without limitation Amarin Pharma, Inc., and to accept any
reasonable office or position with any such affiliate as the Company’s Board of Directors may require, including, but not limited to, service as an officer or director of any such affiliate. 

2. Work Location: Your principal place of employment will be the Company’s offices which are currently located in Bedminster, New
Jersey, subject to business travel requirements. 
 3. Start Date: Unless otherwise agreed, your first day of employment will be
July 5, 2016, or such earlier date as may be mutually determined. 
 4. Salary: The Company will pay you a salary at the annual
rate of $400,000 subject to periodic review and adjustment at the discretion of the Company. Currently our policy is to make salary payments semi-monthly. 

5. Bonuses: You will be eligible to receive annual performance bonuses. The Company will target the bonus of up to 40% of your salary
for the year. The actual bonus is discretionary and will be subject to the Company’s assessment of your performance, as well as business conditions at the Company. The bonus also will be subject to your employment for the full period covered by
the bonus, approval by and adjustment at the discretion of the Company’s Board of Directors or an authorized committee thereof, and the terms of any applicable bonus plan. The Company may also make adjustments in the targeted amount of your
annual performance bonus. Any bonus awarded to you will be paid by March 15 of the year following the bonus year to which such bonus relates. 








 



 
  

 6. Special Bonus: On September15, 2016, you will receive a lump sum bonus of $25,000
(less applicable withholdings and deductions) . In order to not forfeit this special bonus, you must not resign your employment or be terminated for cause prior to July 5, 2017. 

7. Benefits: You will be eligible to participate in the employee benefits and insurance programs generally made available to the
Company’s full-time employees, including health, life, disability and dental insurance. You will be eligible for up to 18 days of paid time off or such other amount determined by the Company, which shall accrue and in other respects be
administered in accordance with the Company’s policy from time to time. You will be reimbursed for all reasonable business expenses you incur while carrying out your duties on behalf of the Company; provided such reimbursement shall be
conditioned on you following the Company’s reimbursement policies and claims procedure, including by providing reasonable documentation of such expenses. 

8. Stock Options: You will be eligible to participate in the Company’s stock option program, subject to approval by the Board of
Directors. After you join the Company, we will recommend the grant to you of an option to purchase 625,000 ordinary shares of the Company. Under current Company policy, the exercise price of your stock option will be equal to the closing price of
the Company’s American Depository Shares (ADS) on The NASDAQ Stock Market at the close of the first trading day of the month following your Start Date. Vesting of such stock option will be scheduled over a four year period with 25% vesting
after one year after your Start Date and the balance vesting monthly over the subsequent thirty-six months. 
 9. Equity: The terms
and conditions of your equity awards shall be set forth in a stock option and/or restricted stock agreements, as applicable, that are expected to substantially reflect the various terms and conditions of the Company’s 2011 Stock Incentive Plan
as may be amended from time to time (collectively the “Equity Documents”) provided, and notwithstanding anything to the contrary in the Equity Documents, Section 8 of this Agreement shall control with respect to any of your equity
interests that are unvested as of the Date of Termination, provided further, nothing herein shall be construed to be less favorable to you than the terms of the Equity Documents. 

10. At-will Employment, Accrued Obligations; Severance: Your employment is “at will” meaning you or the Company may terminate
it at any time for any or no reason. In the event of the termination of your employment for any reason, the Company shall pay you the Accrued Obligations, defined as (1) your base salary through the date of termination, (2) an amount equal
to the value of your accrued unused paid time off days, if any, and (3) the amount of any business expenses properly incurred by you on behalf of the Company prior to any such termination and not yet reimbursed, if any, within ten
(10) days of the last day of your employment (“Date of Termination”). In addition to the Accrued Obligations, in the event the Company terminates your employment without Cause at any time, or during the twenty-four (24) month
period that immediately follows a Change of Control (the “Post-Change in Control 








 



 
  

 
Period”) the Company terminates your employment without Cause or you terminate your employment for Good Reason (defined below), the Company shall provide you with the following termination
benefits (the “Termination Benefits”), depending on the Date of Termination: 
  

	 	(i)	continuation of your base salary then in effect during the “Salary Continuation Period” which shall be either: (A) six (6) months from the Date of Termination, if the Company terminates your
employment without Cause and the Date of Termination occurs at any time outside of the Post-Change in Control Period, or (B) twelve (12) months from the Date of Termination, if the Company terminates your employment without Cause or you
terminate your employment for Good Reason and, in either case, the Date of Termination occurs during the Post-Change in Control Period. Solely for purposes of Section 409A of the Internal Revenue Code of 1986, as amended, each Salary
Continuation Payment during the Salary Continuation Period is considered a separate payment; 

  

	 	(ii)	continuation of group health plan benefits to the extent authorized by and consistent with 29 U.S.C. § 1161 et seq. (commonly known as “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 you become eligible for health benefits through
another employer or otherwise become ineligible for COBRA; 

  

	 	(iii)	if the Company terminates your employment without Cause or you terminate your employment for Good Reason and, in either case, the Date of Termination occurs during the Post-Change in Control Period, a lump sum cash
payment equal to your target annual performance bonus for the year during which the Date of Termination occurs; 

  

	 	(iv)	if the Company terminates your employment without Cause and the Date of Termination occurs outside of the Post-Change in Control Period, six (6) months of accelerated vesting from the Date of Termination with
respect to any of your then outstanding stock options, restricted stock units or other equity incentive awards (in each case, only to the extent subject to time-based vesting); and 


 

	 	(v)	if the Company terminates your employment without Cause or you terminate your employment for Good Reason and, in either case, the Date of Termination occurs during the Post-Change in Control Period, then outstanding
stock options, restricted stock units or other equity incentive awards (whether or not subject to time based vesting) shall immediately vest in full effective upon the Date of Termination. 









 



 
  

 Notwithstanding anything to the contrary in this Agreement, you shall not be entitled to any Termination
Benefits unless you first (i) enter into, do not revoke, and comply with the terms of a separation agreement in a form acceptable to the Company which shall include a release of claims against the Company and related persons and entities (the
“Release”), provided that the Release shall not require you to release (a) claims to enforce your right to receive Termination Benefits; (b) claims for vested benefits pursuant to ERISA; (c) claims with respect to your
vested equity rights as of the Date of Termination; (d) claims to enforce the Company’s obligation to indemnify you to the extent such indemnification obligations exist; and (e) claims which legally may not be waived; (ii) resign
from any and all positions, including, without implication of limitation, as a director, trustee, and officer, that you then hold with the Company and any affiliate of the Company; and (iii) return all Company property and comply with any
instructions related to deleting and purging duplicates of such Company property, in each case within the time period designated by the Company but in no event later than 60 days of the Date of Termination. The Salary Continuation Payments shall
commence within 60 days after the Date of Termination and shall be made on the Company’s regular payroll dates; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, the Salary Continuation
Payments shall begin to be paid in the second calendar year. In the event you miss a regular payroll period between the Date of Termination and first Salary Continuation Payment, the first Salary Continuation Payment shall include a “catch
up” payment. Notwithstanding the foregoing, if you breach any of the material provisions of this Agreement or the Nondisclosure Developments and Non-competition Agreement, in addition to all other rights and remedies, the Company shall have the
right to terminate or cease payment of the Termination Benefits. For the avoidance of doubt, you shall not be entitled to the Termination Benefits in the event your employment ends due to your death or disability. 

11. Definitions: For purposes of this Agreement, the following terms shall have the following meanings: 

“Cause” shall mean: (i) conduct by you constituting an act of material misconduct in connection with the performance of your duties, including,
without limitation, misappropriation of funds or property of the Company other than the occasional, customary and de minimis use of Company property for personal purposes; (ii) the commission by you of (A) any felony; or (B) a
misdemeanor involving moral turpitude, deceit, dishonesty or fraud; (iii) any conduct by you that would reasonably be expected to result in material injury or reputational harm to the Company or any of its subsidiaries and affiliates if you
were retained; (iv) continued non-performance or continued unsatisfactory performance by you of your responsibilities as reasonably determined by the Company’s Board of Directors; (v) a breach by you of any of the material provisions
of any agreement between you and the Company including, without limitation, any agreement relating to non-disclosure, non-competition or assignment of inventions; (vi) a material violation by you of any of the Company’s written policies or
procedures provided that, other than in the case of noncurable events, you are provided with written notice and fifteen (15) days to cure. 
 The
meaning of “Change of Control” shall be limited to the following events, but only to the extent such events constitute a “change in the ownership or effective control” of the Company or a “change in the ownership of a
substantial portion of the Company’s assets” for purposes of Section 409A of the Code: 








 



 
  


	 	(i)	any person or company (either alone or together with any person or company acting in concert with him or it) (an “Acquiring Company”) obtaining Control of the Company, 


 

	 	(ii)	any person or company that Controls the Company becoming bound or entitled to acquire Shares under sections 974 to 991 of the UK Companies Act 2006, 


 

	 	(iii)	any court sanctioning a compromise or arrangement under section 899 of the UK Companies Act 2006, 

  

	 	(iv)	a resolution being tabled for the voluntary winding-up of the Company, 

  

	 	(v)	any Acquiring Company acquiring all or substantially all of the assets of the Company, 

  

	 	(vii)	any merger, reorganization, consolidation or other similar transaction pursuant to which the holders of the Company’s outstanding voting power and outstanding stock immediately prior to such transaction do not own
a majority of the outstanding voting power and outstanding stock or other equity interests of the Company or any resulting or successor entity (or its ultimate parent, if applicable) immediately upon completion of such transaction,


  

	 	(viii)	the sale of all or a majority of the Shares of the Company to an unrelated person, entity or group thereof acting in concert, or 

  

	 	(ix)	any other similar transaction which the Board determines should constitute a Change of Control for the purposes of the Plan. 


“Control” means the ownership of more than fifty (50) percent of the issued share capital or other equity interest of the Company or the legal
power to direct or cause the direction of the general management and policies of the Company. 
 “Good Reason” shall mean that you have complied
with “Good Reason Process” (hereinafter defined) following the occurrence of any of the following Good Reason conditions that occur without your consent: (i) a material diminution of your base salary; (ii) a material diminution
in your authority, duties or responsibilities; (iii) a material change in the principal location where you are required to provide services for the Company (not including business travel and short-term assignments); and/or (iv) a material
breach by the Company of this Agreement. For purposes of this Agreement, “Good Reason Process” shall mean that: (x) you reasonably determine in good faith that a “Good Reason” condition has occurred; (y) you notify the
Company in writing of the Good Reason condition within thirty (30) days of the first occurrence of such condition; (z) you cooperate in good faith with the Company’s efforts, for a period of









 



 
  

 
thirty (30) days following such notice (the “Cure Period”), to remedy the condition; notwithstanding such efforts, the Good Reason condition continues to exist; and you terminate
your employment within thirty (30) days after the end of the Cure Period. If the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred. 

12. Section 280G Limitation: Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any
compensation, payment or distribution by the Company to or for the benefit of you, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with Section 280G
of the Code and the applicable regulations thereunder (the “Severance Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, the following provisions shall apply: 

(a) If the Severance Payments, reduced by the sum of (1) the Excise Tax and (2) the total of the Federal, state, and
local income and employment taxes payable by you on the amount of the Severance Payments which are in excess of the Threshold Amount, are greater than or equal to the Threshold Amount, you shall be entitled to the full benefits payable under this
Agreement. 
 (b) If the Threshold Amount is less than (x) the Severance Payments, but greater than (y) the
Severance Payments reduced by the sum of (1) the Excise Tax and (2) the total of the Federal, state, and local income and employment taxes on the amount of the Severance Payments which are in excess of the Threshold Amount, then the
Severance Payments shall be reduced (but not below zero) to the extent necessary so that the sum of all Severance Payments shall not exceed the Threshold Amount. In such event, the Severance Payments shall be reduced in the following order:
(1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits. To the extent any payment
is to be made over time (e.g., in installments, etc.), then the payments shall be reduced in reverse chronological order. 

(c) For the purposes of this Section, “Threshold Amount” shall mean three times your “base amount” within
the meaning of Section 280G(b)(3) of the Code and the regulations promulgated thereunder less one dollar ($1.00); and “Excise Tax” shall mean the excise tax imposed by Section 4999 of the Code, and any interest or penalties
incurred by you with respect to such excise tax. 
 (d) The determination as to which of the alternative provisions of this
Section 9 shall apply to you shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and you within 15 business
days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or you. For purposes of determining which of the alternative provisions of this Section 9 shall apply, you shall be deemed to pay
federal income taxes at the highest 








 



 
  

 
marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates
of individual taxation in the state and locality of your residence on the date of termination, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. Any determination by the
Accounting Firm shall be binding upon the Company and you. 
 13. Taxes; Section 409A: All forms of compensation referred to in
this letter agreement are subject to reduction to reflect applicable withholdings and payroll taxes and other deductions required by law. You hereby acknowledge that the Company does not have a duty to design its compensation policies in a manner
that minimizes tax liabilities. Anything in this Agreement to the contrary notwithstanding, if at the time of your separation from service within the meaning of Section 409A of the Code, the Company determines that you are a “specified
employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that you become entitled to under this Agreement on account of your separation from service would be considered deferred
compensation subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be
provided until the date that is the earlier of (A) six months and one day after your separation from service, or (B) your death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include
a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. 

All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by you during the time
periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was
incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year. Such right to
reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit. 
 To the extent that any payment or benefit described in
this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the termination of this Agreement, then such payments or benefits shall be
payable only upon your “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h). 
 The parties intend that this Agreement will be administered in accordance with
Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with
Section 409A of the Code. The parties agree that this Agreement may be 








 



 
  

 
amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the
payments and benefits provided hereunder without additional cost to either party. 
 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. 

14. Representation Regarding Other Obligations: This offer is conditioned on your representation that you are not subject to any
confidentiality, non-competition agreement or any other similar type of restriction that may affect your ability to devote full time and attention to your work at the Company. If you have entered into any agreement that may restrict your activities
on behalf of the Company, please provide me with a copy of the agreement as soon as possible. 
 15. Other Terms: Your employment
with the Company shall be on an at-will basis. In other words, you or the Company may terminate employment for any reason and at any time, with or without notice, subject to the Termination Benefits provisions herein. Similarly, the terms of
employment outlined in this letter are subject to change at any time. If you have not already done so, you also will be required to sign the Company’s Nondisclosure Developments and Non-competition Agreement as a condition of this letter
agreement and your continued employment, the terms of which shall be incorporated by reference into this letter agreement. A copy of that letter agreement is enclosed. In addition, this letter agreement is contingent on the completion of references
checks and a background investigation that are satisfactory to the Company (as determined by the Company) and your submission of satisfactory proof of your identity and your legal authorization to work in the United States and a satisfactory
Company-paid initial-employment physical and drug screen, in each case to the extent not already completed. 
 16. Interpretation,
Amendment and Enforcement: This Agreement, including the Company’s Nondisclosure Developments and Non-competition Agreement and the Equity Documents, constitute the complete agreement between you and the Company, contain all of the terms of
your employment with the Company and supersede any prior agreements, representations or understandings (whether written, oral or implied) between you and the Company. The terms of this Agreement and the resolution of any disputes as to the meaning,
effect, performance or validity of this Agreement or arising out of, related to, or in any way connected with, this Agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be
governed by the laws of the State of New Jersey, excluding laws relating to conflicts or choice of law. You and the Company submit to the exclusive personal jurisdiction of the federal and state courts located in the State of New Jersey in
connection with any Dispute or any claim related to any Dispute. 
 17. Assignment: Neither you nor the Company may make any
assignment of this Agreement or any interest in it, by operation of law or otherwise, without the prior written 








 



 
  

 
consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement without your consent to one of its Affiliates or to any person with whom the
Company shall hereafter effect a reorganization, consolidate with, or merge into or to whom it transfers all or substantially all of its properties or assets. This Agreement shall inure to the benefit of and be binding upon you and the Company, and
each of our respective successors, executors, administrators, heirs and permitted assigns.
