corporate records, certificates of public officials and other instruments as we
have deemed necessary or advisable for purposes of this opinion.

                 Based upon the foregoing, we are of the opinion that each of
the Corporation and Capital is a corporation duly organized and validly
existing under the laws of the State of New Jersey.

                 Based upon the foregoing, we are of the further opinion that
when the Registration Statement has become effective under the Act, then:

                 (1)      When the Subordinated Indenture or the Subordinated
         Capital Indenture, as the case may be, if applicable has been duly
         authorized and executed by the parties thereto, the Debt Securities
         and, if applicable, the Senior Guarantees or Subordinated Guarantees,
         as the case may be, when issued in accordance with the terms of the
         relevant Indenture will be valid and binding obligations of the
         Corporation or Capital, as the case may be.

                 (2)      When the issuance of any shares of Common Stock or
         Preferred Stock has been duly authorized under New Jersey law and such
         shares are issued, such shares will be validly issued, fully-paid and 
         nonassessable.

                 (3)      When any Warrant Agreement has been duly authorized
         and executed by the parties thereto, any Warrants when issued in
         accordance with the terms of the relevant Warrant Agreement will be
         valid and binding obligations of the Corporation or Capital, as the
         case may be.

                 (4)      When the Deposit Agreement has been duly authorized
         and executed by the parties thereto, and Preferred Stock has been
         deposited thereunder, any Depositary Shares when issued in accordance
         with the terms thereof will be valid and binding instruments in
         accordance with their terms and the terms of the Deposit Agreement.

In rendering the foregoing opinion, we have relied upon the opinion to you of 
even date herewith of
