Collectively, the Amendment and the Schedule provide for the Operating Partnership’s establishment and issuance of an equal number of Series C Term Preferred Units as are issued by the Company in connection with the Company’s previously announced offering of 7.125% Series C Cumulative Term Preferred Stock (the “Series C Term Preferred Stock”) upon the Company’s contribution to the Operating Partnership of the net proceeds of the Series C Term Preferred Stock offering. Generally, the Series C Term Preferred Units provided for under the Amendment and Schedule have preferences, distribution rights, and other provisions substantially equivalent to those of the Company’s Series C Term Preferred Stock.
