                            [FIRST UNION LETTERHEAD]

Mr. Sidney Lassen
Chief Executive Officer
Sizeler Property Investors, Inc.

Kenner, Louisiana 70062

Dear Mr. Lassen:

            We have reviewed Sizeler's August 2, 2005 press release announcing
amendments to its shareholders rights plan. We wish to reiterate First Union
Real Estate Equity and Mortgage Investments' ("First Union") interest in
participating in any offering by Sizeler of equity or debt securities on a basis
comparable to that offered to others. Moreover, we may be willing to pay a
premium in order to purchase the entire issue. Accordingly, please provide First
Union - or alternatively all Sizeler shareholders - with any such opportunity
contemplated.

            It is First Union's position that Sizeler's offering of securities
in March was in violation of its fiduciary duties, and was consummated with the
aim of entrenching its Board to the substantial monetary harm of its
stockholders. As you are aware, the Circuit Court in and for Baltimore City
observed at our emergency hearing that First Union had raised "grave questions
about this transaction."

            In particular, in light of the state court's stated concern and
First Union's expression of interest, we expect that Sizeler and its Board will
conduct itself appropriately.

                                              Very truly yours,

                                              FIRST UNION REAL ESTATE EQUITY AND
                                              MORTGAGE INVESTMENTS

                                              Michael L. Ashner
                                              Chief Executive Officer
