AMARIN CORPORATION PLC By: /s/ RICHARD A.B. STEWART Name: Richard A.B. Stewart Title: Chief Executive Officer Date: October 7, 2004 EXHIBIT INDEX Index to Exhibits Exhibit Item Sequentially Numbered Page (a) Material event description 4 Contact: Rick Stewart Chief Executive Officer Amarin Corporation plc Phone: +44 (0) 207 907 2442 investor.relations@amarincorp.com Alan Cooke Chief Financial Officer Amarin Corporation plc Phone: +44 (0) 207 907 2442 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.

However, pursuant to the agreement with the investors, the Company is required to register the resale of the securities and the securities issuable upon exercise of the warrant under the Securities Act.
