        <footnote id="F1">Excludes options previously issued by the Issuer to the Reporting Person (the &quot;Options&quot;) to purchase up to 6,042 common shares of beneficial interest, $.01 par value, of the Issuer.  The issuance of the Options has been previously reported and no transactions in connection therewith have occured that are required to be reported herein.</footnote>
        <footnote id="F2">The amounts shown on Tables I and II represent the beneficial ownership of the securities reported in such tables by Five Arrows Realty Securities  III L.L.C. (&quot;FARS&quot;), a portion of which may be attributable to the Reporting Person because the Reporting Person is a manager of Rothschild Realty Investors III L.L.C., which in turn is the managing member of FARS.  The actual pro rata portion of such beneficial ownership that may be deemed attributable to the Reporting Person is not readily determinable because it is subject to several variables.  The Reporting Person disclaims beneficial ownership of these securities to the extent in excess of his pecuniary interest therein.</footnote>
