TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE COMPANY BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH PERSON, WOULD RESULT IN SUCH PERSON BENEFICIALLY OR CONSTRUCTIVELY OWNING CAPITAL STOCK WITH A VALUE IN EXCESS OF 9.8% OF THE VALUE OF THE
COMPANY’S OUTSTANDING CAPITAL STOCK; (iii) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF SERIES K PREFERRED STOCK THAT, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE COMPANY BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH
PERSON, WOULD RESULT IN THE COMPANY BEING “CLOSELY HELD” UNDER SECTION 856(h) OF THE CODE OR OTHERWISE CAUSE THE COMPANY TO FAIL TO QUALIFY AS A REIT; AND (iv) ANY TRANSFER OF SHARES OF SERIES K PREFERRED STOCK THAT, IF EFFECTIVE,

AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF SERIES K PREFERRED STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE COMPANY AT ITS PRINCIPAL OFFICE.
