Amarin Announces $3.0 Million Bridge Financing

Amarin Corporation plc (NASDAQ: AMRN) today announced that it has executed an agreement for the private placement of convertible bridge loan notes (“Bridge Financing”) in the amount of $3.0 million with select accredited and institutional investors, including funds managed by Midsummer Capital, LLC and certain existing investors in the Company.

This Bridge Financing provides the Company with sufficient funds to operate through September 30, 2009, during which time the Company will continue its ongoing discussions with potential investors in order to secure long term equity financing. The Company recently announced that it has signed a non-binding term sheet for a private placement of American Depositary Shares (each representing one ordinary share) (“ADSs”) for up to $55 million in which the lead investors would purchase an aggregate of up to $30 million, with the balance of approximately $25 million reserved for other investors mutually acceptable to both the Company and the lead investors.

This Bridge Financing consists of convertible notes and warrants. The convertible notes are in the principal amount of $3.0 million, and pay interest at the rate of 8% per annum with a maturity date of September 30, 2009. At the option of the lenders, the principal is convertible into Company ADSs (“Conversion ADSs”) at the closing of the Company’s next equity financing prior to their maturity at a price per share equal to the lower of (i) 90% of the per share price in such financing and (ii) the volume weighted average price of the Company’s ADSs on NASDAQ for the 30 trading day period ending on the closing date of the Bridge Financing. The warrants are of a five year duration and entitle the holders thereof to receive common stock equal to 50% of the Conversion ADSs at an exercise price equal to the per share price paid in the Company’s next equity financing. If the bridge loan notes are converted in connection with the next equity financing, the holder will participate on the same terms and conditions as any other cash investor, including the right to receive, in addition to the ordinary shares of the Company issuable upon conversion of the loan notes, warrants having the same terms as those, if any, issued to the investors in the next equity financing.

In connection with this Bridge Financing, the lenders under a currently outstanding $2.5 million bridge loan agreed to extend the maturity date of their loan notes to September 30, 2009.

No assurance can be given regarding whether, or on what terms, the Company will be able to secure longer term financing in order to permit the continued funding of the Company’s operations beyond September 30, 2009.

This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities. There shall not be any sale of these securities in any jurisdiction in which such offering would be unlawful.
