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

4. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $18.00 to $18.01, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range.
5. The stock option granted to the Reporting Person is fully vested as of the date hereof.
6. On May 20, 2019, the Reporting Person was granted an option to purchase 9,658 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 20, 2019 or (ii) the Issuer's annual general meeting of shareholders in 2020.
7. 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.
8. On May 20, 2019, the Reporting Person was granted 7,428 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 20, 2019 or (ii) the Issuer's annual general meeting of shareholders in such year.
9. Not applicable.
