That the Board of Directors duly adopted resolutions proposing to amend and restate the Certificate of Incorporation of this corporation, declaring said amendment and restatement to be advisable and in the best interests of this corporation and its stockholders, and authorizing the appropriate officers of this corporation to solicit the consent of the stockholders therefor, which resolution setting forth the proposed amendment and restatement is as follows:

The name of its registered agent for service of process in the State of Delaware at such address is Corporation Service Company.

THIRD: The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware, as from time to time amended.

FOURTH: The total number of shares of capital stock which the Corporation shall have authority to issue is (i) 12,999,999 shares of Common Stock

having a par value of $0.01 per share; and (ii) one share of Preferred Stock, having a par value of $0.01 per share, and which is hereby designated as the “Special Voting Share” (the “Special Voting Share”). Except as otherwise provided by law, the Common Stock of the Corporation may be issued by the Corporation from time to time in such amounts, for such consideration and for such corporate purposes as the board of directors of the Corporation (the “Board of Directors”) may from time to time determine.

The following is a statement of the designations and the powers, privileges and rights, and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation.

1. General. The voting and liquidation rights of the holders of the Common Stock are subject to and qualified by the rights, powers and preferences of the holders of the Preferred Stock set forth herein.

2. Voting. The holders of the Common Stock are entitled to one vote for each share of Common Stock standing in such holder’s name on the books of the Corporation held at all meetings of stockholders (and written actions in lieu of meetings); provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to the Certificate of Incorporation that relates solely to the terms of one or more outstanding class or series of Preferred Stock if the holders of such affected class or series are entitled, either separately or together with the holders of one or more other such class or series, to vote thereon pursuant to the Certificate of Incorporation or pursuant to the General Corporation Law. There shall be no cumulative voting. The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of shares of capital stock of the Corporation representing a majority of the votes represented by all outstanding shares of capital stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law.

3. Dividends. The holders of the Common Stock shall be entitled to receive dividends as may be declared from time-to-time by the Corporation’s Board of Directors and Dividend Committee, out of funds legally available for that purpose.
