AMARIN CORPORATION RAISES $12.75 MILLION IN PRIVATE PLACEMENT
OF ORDINARY SHARES

- $3 million of existing debt converted into ordinary shares -

LONDON, United Kingdom, October 7, 2004 - Amarin Corporation plc
(NASDAQSC: AMRN) today announced that it has completed a private
placement of 13,448,546 ordinary shares to a group of new and existing
accredited investors and management, raising gross proceeds to the
Company of $12.75 million.

The purchase price of $0.947 per share was based on the average closing price
of Amarin's American Depositary Shares on Nasdaq for the ten trading days
ended October 6, 2004. Amarin intends to file a registration statement with
the U.S. Securities and Exchange Commission within 60 days covering the
ordinary shares sold to investors.

As previously announced, following Mr. Thomas Lynch's purchase of Elan
Corporation plc's (Elan) entire debt and equity interest in Amarin, $3 million
of the outstanding $5 million Loan Notes acquired were converted into ordinary
shares immediately following the closing of this private placement. The debt
was converted at a price of $1.104, a 16.6% premium to the private placement
price. Amarin's management investing in the private placement also bought shares
at this higher price to comply with Nasdaq rules. The remaining $2 million of
Loan Notes can be converted into ordinary shares at the option of the holder at
the offer price of any subsequent equity financing.

Rick Stewart, chief executive officer of Amarin, commented, "This successful
financing allows Amarin to drive forward with its plans for the phase III
clinical trials with Miraxion(TM), our lead compound for Huntington's disease.
Additionally, it will facilitate in-licensing discussions for new late-stage
compounds and out-licensing discussions with prospective partners for
indications outside neurology."

Amarin's future financing strategy will depend on the timing of clinical trial
expenditure on Amarin's development pipeline, in particular the proposed phase
III trials with Miraxion(TM) in Huntington's disease, plus the revenue generated
from its licensing and partnering activities. As previously described, Amarin
is seeking to partner the rights to its development pipeline for all indications
outside neurology and for geographic markets outside the U.S. Amarin plans to
directly commercialize its pipeline in the U.S. neurology market.
Amarin also announced today that the settlement agreement with Valeant
Pharmaceuticals International (Valeant), announced on September 29, 2004,
is now unconditional, as all conditions precedent to closing have been met.

Since September 29, 2004, Amarin has announced a number of transactions which
add approximately $16 million to its shareholders' equity. The announcements are
summarised as follows:

  -  On September 29, Amarin announced that it had reached a settlement
agreement with Valeant whereby $6 million of the $8 million in contingent
milestones due to Amarin from Valeant were waived.  The remaining $2 million
is now no longer contingent and is payable by Valeant to Amarin on November 30,
2004.  After deducting $1 million due to Elan under the asset purchase agreement
the net benefit to Amarin's shareholders' equity is $1 million; and

  -  On October 1, Amarin announced that its non-executive chairman, Mr. Thomas
Lynch, had acquired Elan's entire debt and equity interest in Amarin, including
the $5 million Loan Notes. Mr. Lynch has agreed to convert $3 million of the $5
million Loan Notes into ordinary shares. This debt conversion, which took place
today, will improve Amarin's shareholders' equity by $3 million; and

  -  Today, Amarin announced the completion of a $12.75 million private
placement, which will improve Amarin's shareholders' equity by
approximately $12 million.

Rick Stewart continued, "Our original objective was to raise approximately $10
million, however significant investor interest increased that amount to $12.75
million.  We limited the fund raising to $12.75 million in order to restrict
shareholder dilution, even though we had demand in excess of this level."

Amarin had been previously informed by Nasdaq that it did not comply with
the minimum shareholders' equity threshold of $2.5 million as set forth in
Marketplace Rule 4310(c)(2)(B) ('the Rule'). Amarin believes that the
improvement in Amarin shareholders' equity as outlined above restores Amarin's
compliance with the Rule. Nasdaq will continue to monitor the Company's ongoing
compliance with the Rule and, if at the time of its next relevant periodic
report the Company does not evidence compliance, it may be subject to delisting.
