The Units acquired in this transaction are redeemable beginning 6/11/2010 for cash equal to the contemporaneous market price of shares of beneficial interest in the issuer or, at the election of the issuer, for a like number of shares of beneficial interest in the issuer, without payment of any conversion or exercise price.  The other Units held directly by the reporting person are currently redeemable, but have not been redeemed.  The Units have no expiration date.</footnote>
        <footnote id="F2">These Units were acquired as part of the consideration for the Registrant's acquisition of interests in Bala Cynwyd Associaties, L.P. from the reporting person.</footnote>
        <footnote id="F3">The Units are generally redeemable one year after the date of issuance in consideration for cash equal to the contemporaneous market price of shares of beneficial interest in the issuer or, at the election of the issuer, for a like number of shares of beneficial interest in the issuer, without payment of any conversion or exercise price.  These Units are currently redeemable, but have not been redeemed.  The Units have no expiration date.</footnote>
