Item 8.01. Other Events.

Amarin Corporation plc ("Amarin") previously guided that it would make a decision to hire prospective sales representatives as part of its continued VascepaŽ commercialization preparations before the end of November 2012. Amarin now expects to make this decision in the first half of December 2012 and continues to anticipate the launch of Vascepa early in the first quarter of 2013.

This Current Report on Form 8-K contains forward-looking statements, including statements concerning the timing of Amarin's decision to hire prospective sales representatives for Vascepa commercialization and the timing of a commercial launch of Vascepa. These forward-looking statements are not promises or guarantees and involve substantial risks and uncertainties. Among the factors that could cause actual results to differ materially from those described herein include the following: uncertainties associated generally with the launch of new pharmaceutical products and the commercialization path for Vascepa, such as Amarin's ability to negotiate and execute a successful acquisition of Amarin or a strategic collaboration with a third party for the commercialization of Vascepa, or launch the product on its own and other risks associated with preparations associated with a commercial launch. A more complete list and description of risks, uncertainties and other matters related to an investment in Amarin can be found in Amarin's filings with the U.S. Securities and Exchange Commission, including the "Risk Factors" section in its most recent Quarterly Report on Form 10-Q.
