The Reverse Stock Split shall occur automatically without any further action by the holders of the shares of Common Stock affected thereby. All rights, preferences and privileges of the Common Stock shall be appropriately adjusted to reflect the Reverse Stock Split in accordance with this Amended and Restated Certificate of Incorporation.”
