The purchase price of $3.4785 per share was based on the average closing price of Amarin's American Depositary Shares for the five trading days ended 14th January 2003. Amarin intends to file a registration statement with the U.S. Securities and Exchange Commission within 90 days covering the ordinary shares sold to investors. Furthermore, as a result of the financing transaction, share ownership in Amarin by certain affiliates of Elan Corporation plc (NYSE:ELN) ("Elan") has been reduced from 39.3% to approximately 25.9% on a fully diluted basis. Rick Stewart, chief executive officer of Amarin, commented, "the completion of the financing has enabled Amarin to attract several new high-quality institutional investors to the Company and has strengthened our balance sheet. This additional capital will enable us to fund the potential launch of Zelapar ( tm ), for Parkinson's disease and LAX-101, for Huntington's disease, in 2003 and expand the Amarin specialist neurology sales force to support these product launches." Additionally, Amarin announced that it has reached an agreement with Elan to restructure certain terms of its existing commitments including the following: - The deferral of $10 million and $15 million in debt repayments, due in September 2003 and 2004, by one year. These debt repayments were incurred in connection with Amarin's acquisition of U.S. rights to Permax ( r ) (pergolide mesylate) from Elan; - Reduction by a total of $7.5 million in quarterly deferred option payments due in 2004 and 2005, also incurred in connection with the acquisition of the Permax rights; - Increase by $5 million of a revenue contingent milestone payment included in Amarin's existing option to acquire the U.S. rights to Zelapar (orally disintegrating selegiline tablets). The increase of $5 million will become payable to Elan without contingency upon Amarin receiving proceeds from the disposal of certain non-core assets (see below); - Inclusion of Elan's shares in the registration statement to be filed for the investors described above. Elan has agreed not to sell any of those shares until October 1, 2003, with certain exceptions; and - Including a $17.5 million debt repayment made in January 2003, Amarin has to date paid Elan a cumulative total of $35 million in relation to the acquisition cost of Permax. Outstanding indebtedness to Elan relating to the Permax acquisition totals $42.5 million as at 28th January 2003. Amarin plans to dispose of certain non-core assets including products in its Primary Care Product line and will utilise the proceeds to meet remaining obligations to Elan at the earliest possible opportunity. Rick Stewart continued, "the key priorities for Amarin in 2003 are to maximise the probability of successful product launches for Zelapar and LAX-101; to expand the sales force to support those launches and to refill our neurology product development pipeline with high-quality development candidates."
