Nordion International Provides Updated Schedule for MAPLE Arbitration

OTTAWA, Oct. 21, 2011 /PRNewswire/ - Nordion Inc. (TSX: NDN) (NYSE: NDZ), a leading provider of products and services to the global health science market, today released an update to the schedule for the ongoing arbitration with Atomic Energy of Canada Limited (AECL) relating to the MAPLES, the nuclear reactors that were being commissioned to serve as the Company’s source of long-term medical isotope supply.

The dates for the hearings that had originally been scheduled to be completed by the end of 2011 will be extended to the second fiscal quarter 2012. This extension is required to allow further evidence from the parties to be heard. Based on the current status of the hearings, we believe this new schedule allows sufficient time for completion of the arbitration and a decision thereafter from the panel.

Nordion served AECL with a notice of arbitration proceedings on July 8, 2008, after AECL and the Government of Canada unilaterally announced their intent to discontinue development work on the MAPLE facilities. The arbitration seeks to compel AECL to fulfil its contractual obligations to Nordion to complete the MAPLES and, in the alternative and in addition to such order, to pay significant monetary damages.
