In connection with the previously announced cancellation of Energy Conversion Devices, Inc.’s (“ECD”) auction of the going-concern sale of United Solar Ovonic LLC (“USO”), the discontinuance of the court-approved sale process because of the failure to receive an acceptable qualified bid by the bid deadline and the reduction of its workforce, ECD terminated the employment of Jay B.

Andrews, its Executive Vice President and Chief Financial Officer, effective as of July 6, 2012. Messrs.
