(&quot;Issuer&quot;). Issuer is the sole stockholder of the general partner of the Operating Partnership.

Upon the occurrence of certain events, OP Units are redeemable by the holder, without consideration, for an equivalent number of shares of Issuer's common stock or for the cash value of such shares, at Issuer's election.</footnote>
