        <footnote id="F2">As previously reported, on May 15 2017, the Reporting Person was granted 220,000 Restricted Stock Units (&quot;RSUs&quot;) under the Amarin Corporation plc 2011 Stock Incentive Plan (the &quot;Plan&quot;). These RSUs consist of 3 tranches representing 25%, 25% and 50% of the total award. Each tranche vests ratably over 36 months beginning Sept. 30 2018 subject to achievement of certain prespecified performance criteria and continued service of the Reporting Person as provided in the RSU Award Agreement between the Issuer and Reporting Person. On Feb. 25 2021, pursuant to reporting of audited net total revenue for 2020 exceeding $500 million, the performance criteria related to the 50% tranche was deemed achieved, resulting in the vesting of 88,614 RSUs (29 of 36 months' worth). The remaining RSUs in this tranche will continue to vest over 7 monthly installments, the first of which vested Feb. 26 2021. The performance criteria related to both 25% tranches were previously deemed achieved (see Footnote 5).</footnote>

The tranches vest ratably over 36 months beginning September 30, 2018 subject to achievement of the performance criteria and continued service of the Reporting Person as provided in the RSU Award Agreement between the Issuer and Reporting Person. The thirtieth vesting event occurred on February 26, 2021.</footnote>
