                  inclusive, to the Second Amended and Restated Limited

copies conform to the originals of such Documents. Our review has been limited
to examining the Documents and applicable law.

         To the extent that any opinion in this letter relates to or is

         Based upon, subject to and limited by the foregoing, we are of the
opinion that, as of the date hereof:

         1.       The Shares that may be issued in the future in exchange for
                  Common OP Units (as such term is defined in the Registration
                  Statement) have been duly authorized.

         2.       Upon issuance in the manner described in the Registration
                  Statement of the Shares that are to be issued in exchange for
                  the Common OP Units, such Shares will be validly issued, fully
                  paid, and non-assessable.

         We hereby consent to the filing of this opinion letter as Exhibit 5.1
