FIRST: The Corporation’s Amended and Restated Certificate of Incorporation is hereby amended by deleting Section 4.1 thereof in its entirety and replacing the following in lieu thereof:

AUTHORIZED SHARES.  The total number of shares of all classes of capital stock which the Company shall have authority to issue is 202,000,000 shares, of which:

SECOND: The Corporation’s Amended and Restated Certificate of Incorporation was filed with the Secretary of State of the State of Delaware on May 19, 2011.
