      Notwithstanding the foregoing provisions of this Article, each director
shall serve until his or her successor is duly elected and qualified or until
his or her death, resignation, or removal. No decrease in the number of
directors constituting the Board of Directors shall shorten the term of any
incumbent director.

      Any vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal, or other causes shall be filled by either (i) the
affirmative vote of the holders of a majority of the voting power of the
then-outstanding shares of voting stock of the Corporation entitled to vote
generally in the election of directors voting together as a single class; or
(ii) by the affirmative vote of a majority of the remaining directors then in
office, even though less than a quorum of the Board of Directors. Newly created
directorships resulting from any increase in the number of directors shall,
unless the Board of Directors determines by resolution that any such newly
created directorship shall be filled by the stockholders, be filled only by the
affirmative vote of the directors then in office, even though less than a quorum
of the Board of Directors. Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the class of
directors in which the new directorship was created or the vacancy occurred and
until such director's successor shall have been elected and qualified.

      In the event of an increase in the authorized number of directors, the
newly created directorship shall be assigned to one of the above-referenced
classes in accordance with resolutions adopted by the board of directors. No
decrease in the authorized number of directors shall have the effect of
shortening the term of any incumbent director.

Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of this Corporation.

lieu of a meeting.
