Registrant&#8217;s Board of Trustees (the &#8220;Board&#8221;) approved the First Amendment to Amended and Restated Bylaws (the &#8220;Amendment&#8221;), which amends Article II, Section 8 and Article XIV of the Registrant&#8217;s Amended and Restated Bylaws (the &#8220;Bylaws&#8221;).  The Amendment modifies the voting standard applicable to elections of trustees to the Board.  Pursuant to the Amendment, trustees will be elected, in Uncontested Elections (as defined in the Amendment), by the affirmative vote of a majority of the total votes cast for and against such nominees at a meeting of shareholders duly called and at which a quorum is present in order to be elected.  The Amendment also establishes actions required by the Board in the event that a nominee currently serving on the Board fails to receive the affirmative vote of a majority of the total votes cast for and against such nominee in an Uncontested Election.  In addition, the Amendment requires shareholder approval for future amendments or revisions to the voting provisions in the Bylaws pertaining to Uncontested Elections.  </font></div><div
