VANCOUVER – Inex Pharmaceuticals Corporation (“INEX”; TSX: IEX) announced today that it has been advised that an aggregate of US $27,015,000 in principal amount of promissory notes issued by a subsidiary of INEX to a subsidiary of Elan Corporation, plc has been assigned to a group of U.S. and Canadian institutional investors.  GMP Securities Ltd. acted as principal acquiring the notes from Elan’s subsidiary and resold them to the investors.  INEX understands that a majority of the notes were acquired by U.S. institutions.

The notes were issued in April 2001 as INEX convertible notes of US$12 million and US$15 million, plus cumulative interest on each of 7% per year. These notes can be converted into INEX common shares at conversion rates of US$5.71 and US$5.07 per share, respectively.  INEX recently received approval from the Toronto Stock Exchange for the issuance of additional shares to provide for full coverage on the conversion of the notes, including all cumulative interest to the maturity date of April 27, 2007.  The notes are convertible into a maximum of 7,342,614 common shares of INEX, being the maximum number issuable if converted just prior to maturity on April 27, 2007.  Monksland Holdings, B.V., a wholly-owned subsidiary of Elan, originally acquired the notes as part of a joint venture established with INEX in 2001.  The joint venture was terminated in 2003 after Elan determined it would exit the oncology marketplace.
