     (d) The Funds have the right to receive all dividends on the ordinary
shares.
 
     (e) Not applicable.

 
Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect
to Securities of the Issuer.

     The Funds are a party to the Purchase Agreement. The Purchase Agreement
provides the purchasers of shares with the right to receive additional ordinary
shares if Amarin does not meet certain operating cash flows tests ("Cash Flow").
Generally, if either Amarin and its consolidated subsidiaries or Amarin's U.S.
subsidiaries fail to achieve Cash Flow of at least US$4,500,000 during the 12
months ending June 30, 2001, then the purchasers of ordinary shares in the
offering will issued additional ordinary shares by Amarin. The number of
additional ordinary shares to be issued is based on a sliding-scale formula.
Generally, if Cash Flow is less than US$4,500,000, each purchaser will be
entitled to receive one full share for each share purchased. If Cash Flow is
greater than US$4,500,000, but less than US$5,500,000, each purchaser will be
issued a fraction of a share for each share purchased depending on where Cash
Flow falls between US$4,500,000 and US$5,500,000, i.e., if Cash Flow is
US$5,000,000, each purchaser would receive one-half a share for each share

purchased. If Cash Flow exceeds US$5,500,000 no additional shares will be
issued. The right to receive additional shares is not transferable by purchasers
except to their affiliates.

     Except as described in this Schedule 13D, there are no contracts,
arrangements, understandings, or relationships (legal or otherwise) among the
persons named in Item 2 and between such persons and any person with respect to
any securities of the Issuer, including transfer or voting of any of the

calls, guarantees of profits, division of profits of loss, or the giving or
withholding of proxies.
