dated March 18, 2005, and as further amended by Amendment No. 15 to Schedule 13D
dated March 22, 2005 (the "13D"). Capitalized terms used but not defined herein
have the meanings ascribed to them in the 13D.

      Item 4. Purpose of Transaction.

      Item 4 is hereby amended as follows:

      On March 22, 2005, First Union elected to dismiss its Maryland State Court
action brought last week against the Issuer without prejudice. According to
First Union's court filing:

      "in light of the extraordinary step by Sizeler Property Investors, Inc.
      and every member of its board individually to seek a declaratory judgment
      in the federal District Court of Maryland that their conduct in connection
      with the March 15, 2005 sale of stock at issue in the instant case was not
      a breach of fiduciary duty or otherwise improper. As First Union believes
      that it will prevail on the merits and does not wish to distract from the
      substantive questions by an ancillary dispute over the forum, it will join
      the issue in the federal court forum selected by Sizeler and its board."

      Also on March 22, 2005 First Union issued a press release with respect to
the dismissal and noted in its press release that the judge in the State Court
action stated "I agree that [First Union] has, in my view, raised grave
questions about this transaction." Unfortunately, however, the Court concluded
that because the stock issuance had been consummated earlier that morning,
shortly after it was announced by Sizeler, he had no ability to issue the
temporary restraining order.

      A copy of the Press Release is attached as Exhibit 13 hereto and is
incorporated herein by reference.



      Item 7. Materials to be Filed as Exhibits.

      Exhibit 13. Press Release issued March 22, 2005 with respect to dismissal
                  of State Court action.



                                   Signatures

      After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
