     AMARIN CORPORATION SELLS AMARIN DEVELOPMENT TO WATSON
                    PHARMACEUTICALS, INC.


LONDON, United Kingdom, October 28, 2003  Amarin Corporation plc (NASDAQ: AMRN)
today announced the sale of Gacell Holdings AB, the Swedish holding company of
Amarin Development AB (ADAB), its Swedish drug development subsidiary, to
Watson Pharmaceuticals, Inc. ("Watson") (NYSE: WPI). Under the terms of the
sale agreement Watson agreed to pay approximately $15 million in cash to settle
inter-company debts and acquire the stock of ADAB.

ADAB develops technically challenging products utilising advanced, proprietary
product development technologies. ADAB was responsible for developing Watson's
generic formulations of glipizide extended release tablets for which Watson
received Food and Drug Administration approval of the 5mg strength on September
8, 2003.

"The sale of Amarin Development allows us to increase our focus in the field of
neurology, specifically in Parkinson's and Huntington's disease. The proceeds
will contribute significantly to the reduction in financial obligations to Elan
and will provide ongoing working capital" commented Rick Stewart, Chief
Executive Officer of Amarin.

Amarin will apply ninety percent of the net sale proceeds of ADAB toward
repayment of its financial obligations to Elan Corporation, plc and certain of
its affiliates (together "Elan").  Amarin recently announced a restructuring of
its financial obligations to Elan. On payment of $30 million to Elan prior to
December 31, 2003, Amarin will have no further financial obligations to Elan.

Amarin Corporation, plc is a specialty pharmaceutical company focused on
neurology.  The Company plans to become a leader in these therapeutic
categories by providing innovative products and solutions that address
significant unmet medical needs.  Amarin has nine pharmaceutical products on
the US market along with a development pipeline that includes two late-stage
candidates: Zelapar 'TM' (selegiline orally disintegrating tablets), for
Parkinson's disease, and LAX-101, a proprietary compound for Huntington's
Disease.
