Attached hereto is Amendment No. 18 to First Union Real Estate Equity and
Mortgage Investment's Schedule 13D with respect to common stock of Sizeler
Property Investors, Inc. ("Sizeler"), filed today with the Securities and
Exchange Commission (the "SEC"). The amendment attaches a March 27, 2005 press
release that provides the text of an open letter to Sizeler shareholders from
First Union addressing certain claims made by Sizeler in their previous press
releases.

First Union previously notified Sizeler of its intention to file a proxy
statement and other relevant documents with the SEC in support of the election
as directors of Sizeler of Michael L. Ashner, Peter Braverman and Steven Zalkind
at Sizeler's 2005 Annual Meeting of Stockholders. INVESTORS ARE URGED TO READ
THE DEFINITIVE PROXY STATEMENT WHEN IT BECOMES AVAILABLE AND ANY OTHER RELEVANT
DOCUMENTS FILED WITH THE SEC BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION.
You will be able to obtain the documents free of charge at the SEC's website,
www.sec.gov. First Union and Messrs. Ashner, Braverman and Zalkind may be deemed
to be participants in the solicitation of proxies from the shareholders of
Sizeler in connection with the annual meeting. Information about these
participants is set forth in the preliminary proxy statement filed by First
Union with the SEC. Investors may obtain additional information regarding the
interests of such participants by reading the definitive proxy statement when it
becomes available.
