of the Northrop Corporation Employee Insurance

           have the right to direct the manner in which
shares of common stock shall be voted at all

expressed the view that, under certain
circumstances, ERISA may require the Trustee to
vote shares which are not allocated to

Since, in the view of Bankers Trust New York
Corporation, Bankers Trust Company, and BT
Variable, Inc., such voting power is merely a
residual power based upon the occurrence of an
