("UPCO"),  (iii) Elinor F. Urstadt,  (iv) Urstadt Realty  Associates Co LP, a
Delaware limited partnership,  by UPCO as its sole general partner  ("URACO"),
and (v) Willing L. Biddle.  The reporting persons set forth in (i) - (v) of the

         Under the Issuer's Excess Benefits and Deferred Compensation Plan (the
         "Compensation Plan Trust") for the benefit of Mr. Urstadt and the
         1,901,006 shares of Common Stock held by URACO, results in Mr. Urstadt
         beneficially owning 2,943,099 shares of Common Stock, or 38.6 % of the
         7,620,462 shares of Common Stock outstanding as of April 21, 2006.

         Stock, or 32.0% of the 7,620,462 shares of Common Stock outstanding as
         of April 21, 2006.

         Mrs. Urstadt is the direct beneficial owner of 21,300 shares of Common

         URACO is the beneficial owner of 1,901,006 shares of Common Stock
         (including 100,000 shares of Common Stock acquired from the Urstadt
         Conservation Foundation, which no longer owns any shares of Common
         Stock), constituting 24.9% of the 7,620,462 shares of Common Stock
         outstanding as of April 21, 2006.

         Mr. Biddle is the direct beneficial owner of 1,376,775 shares of Common
         Stock individually, which, when added to the 5,030 shares of Common

         Common Stock held by the Compensation Plan Trust for the benefit of Mr.
         Biddle and the 1,070 shares of Common Stock held by the Charles and
         Phoebe Biddle Trust UAD 12/20/93 for the benefit of the issue of Mr.

         or 18.2% of the 7,620,462 shares of Common Stock outstanding as of
         April 21, 2006.
