                  redesignated "Class I Common Stock." The Class I Common Stock
                  shall retain the same preferences, conversions and other
                  rights, voting powers, restrictions, limitations as to
                  dividends, qualifications, and terms and conditions of
                  redemption of the former Class A Common Stock; and

                  (ii) The Class D Common Stock of each Series is hereby
                  redesignated "Class A Common Stock." The Class A Common Stock

                  rights, voting powers, restrictions, limitations as to
                  dividends, qualifications, and terms and conditions of
                  redemption of the former Class D Common Stock.

         THIRD: These Articles of Amendment have been approved by a majority of
the entire Board of Directors of the Corporation and are limited to a change
expressly authorized by Section 2-605 of the Maryland General Corporation Law
