                  of
                  Section 5.2 of the Amended and Restated Bylaws of the Company (the
                  "Sixth Amendment").  Specifically, the Sixth Amendment, which
                  was adopted effective as of December 11, 2007, allows for a Direct
                  Registration System whereby the issuance, recordation, and transfers
                  of
                  the Company's shares may be made by electronic or other means not
                  involving the issuance of certificates and provides that shares
                  of the
                  Company shall be represented by certificates, provided that the
                  Board may
                  provide by resolution or resolutions that shares may be issued
                  in
                  uncertificated form.  The Board adopted the Sixth Amendment to
                  comply with Section 501.00 of the New York Stock Exchange Listed
                  Company Manual
,
which includes the requirement that
                  securities listed on the New York Stock Exchange be eligible for
                  direct
                  registration by January 1, 2008. The Board also approved the Amendment
                  and
                  Restatement of the Bylaws of the Company so as to include the Sixth
                  Amendment therein.

                  Amendment contained herein is qualified in its entirety by the
