INEX Pharmaceuticals Announces Appeal Date

VANCOUVER, March 15 /PRNewswire-FirstCall/ - Inex Pharmaceuticals Corporation announced today that on May 18, 2006 the British Columbia Court of Appeal will hear INEX’s appeal of the Supreme Court of British Columbia’s ruling that provided the holders of INEX’s outstanding convertible promissory notes the right to vote on INEX’s Plan of Arrangement to spin out its Targeted Immunotherapy assets into a new company, Tekmira Pharmaceuticals Corporation (“Tekmira”).

At the same time, the Court of Appeal will also hear an appeal from Stark Trading and Shepherd Investments Ltd. (collectively “Stark”). Stark is appealing the Supreme Court of British Columbia’s decision to dismiss a bankruptcy petition and the ruling that the spin-out of Tekmira can take place given the terms of the convertible debt.

INEX believes that the decisions of the Supreme Court dismissing the bankruptcy petition and ruling that the spin-out can take place given the terms of the convertible debt were correct rulings and INEX will continue to defend its position with respect to these decisions.

Stark is the majority holder of certain promissory notes issued by Inex International Holdings, a subsidiary of INEX. The promissory notes are not due until April 2007 and can be repaid in cash or in shares, at INEX’s option, at maturity.
