(1) The Ordinary Shares may be represented by American Depositary Shares, each of which currently represents one Ordinary Share.
(2) On January 8, 2014, the Reporting Person was granted 19,500 restricted stock units ("RSUs") under the Amarin Corporation plc 2011 Stock Incentive Plan. These RSUs vest in three equal annual installments on each of January 31, 2015, January 31, 2016 and January 31, 2017. The first vesting event occured on January 31, 2015. Upon vesting of the RSUs, the Reporting Person had the option to have the Issuer withhold shares from the total number of shares delivered in respect of withholding taxes due upon such vesting. Instead, the Reporting Person elected to pay withholding taxes to the Issuer in cash and receive the full number of shares vested.
(3) Not applicable.
(4) Each RSU represents a contingent right to receive one Ordinary Share or cash in lieu thereof at the Issuer's discretion.
(5) On February 2, 2015, the Reporting Person was granted an option to purchase an aggregate of 70,000 Ordinary Shares under the Amarin Corporation plc 2011 Stock Incentive Plan pursuant to two separate option grants covering 35,000 Ordinary Shares each. The shares subject to these option shall vest and become exercisable in 48 equal monthly installments on the last day of each month starting on February 28, 2015.
