Except as otherwise provided for or fixed by or pursuant to the provisions of Article IV of this Certificate of Incorporation or any resolution or resolutions of the Board of Directors providing the issuance of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect additional directors under specified circumstances, the Board of Directors shall consist of not fewer than 8 nor more than 15 directors, the exact number of directors within such limits to be determined solely by the Board of Directors in the manner set forth in the Bylaws of the Corporation. Commencing with the 2013 annual meeting of stockholders, directors shall be elected for a term ending on the date of the next annual meeting of stockholders following their election and until their successors shall have been duly elected and qualified, or until their earlier death, resignation or removal.
