Unless the declaration of trust of the real estate investment trust provides otherwise: If the shareholders of any class or series are entitled separately to elect one or more trustees, a trustee elected by shareholders of that class or series may not be removed without cause except by the affirmative vote of a majority of all the votes of that class or series; If a real estate investment trust has cumulative voting for the election of trustees and less than the entire board is to be removed, a trustee may not be removed without cause if the votes cast against the trustee’s removal would be sufficient to elect the trustee if then cumulatively voted at an election of the entire board of trustees, or, if there is more than one class of trustees, at an election of the class of trustees of which the trustee is a member; and If the trustees have been divided into classes, a trustee may not be removed without cause.
