Explanation of Responses:

1. On May 15, 2017, the Reporting Person was granted an option to purchase 25,845 Ordinary Shares under the Amarin Corporation plc 2011 Stock Incentive Plan (the "Plan"). The option shall vest and become exercisable in a single annual installment upon the earlier of (i) the anniversary of the grant date of May 15, 2017 or (ii) the Issuer's annual general meeting of shareholders in 2018.

2. The Ordinary Shares may be represented by American Depositary Shares, each of which currently represents one Ordinary Share.

3. Each Restricted Stock Unit ("RSU") represents a contingent right to receive one Ordinary Share or cash in lieu thereof at the Issuer's discretion, with settlement to be made on a deferred basis, specifically upon the non-employee director's separation of service with the Issuer.

4. On May 15, 2017 the Reporting Person was granted 17,974 RSUs under the Plan. The RSUs vest in equal annual installments over a three year period, with each installment vesting upon the earlier of (i) the anniversary of the grant date of May 15, 2017 or (ii) the Issuer's annual general meeting of shareholders in such year.

5. Not applicable.

Remarks:

These grants are made in accordance with the Issuer's previously disclosed non-employee director compensation program. In the event of a Change of Control (as defined in the Plan), each of the grants described in this Form 4 vests in full.
