        <footnote id="F1">On June 6, 2011, the reporting person inadvertently reported the beneficial ownership of an aggregate of 36,463 options to purchase common shares of beneficial interest.  The purpose of this amendment is to properly reflect that, as of June 2, 2011, the reporting person beneficially owned only an aggregate of 33,130 options to purchase common shares of beneficial interest.</footnote>
