Delaware limited liability company ("Five Arrows"), and Rothschild Realty

Member of Five Arrows ("Rothschild"), on September 15, 1998 and as amended by
Amendment No. 1 on May 21, 1999, Amendment No. 2 on May 24, 1999, Amendment No.

Maryland real estate investment trust, whose principal executive offices are
located at 20 Soundview Marketplace, P.O. Box 1679, Port Washington, NY 11050.
Except as specifically provided herein, this Amendment does not modify any of
the information previously reported on Schedule 13D.

     Item 5.  Interest in Securities of the Issuer
