The Board of Directors of each Subsidiary (as defined below), in its discretion, shall designate those officers of such Subsidiary who will participate in the Plan for each Plan Year. The Participants for each Plan Year normally will be designated by the applicable Board of Directors prior to the beginning of the year; provided, however, for the Plan Year beginning January 1, 1997, Participants who are employed by a Subsidiary may be designated by the Board of Directors of such Subsidiary no later than [February 28, 1997].

For purposes of the Plan, 'Subsidiary' means any company during any period in which it is a 'subsidiary corporation' as that term is defined in section 424(f) of the Internal Revenue Code with respect to the Company."
