B.            transfers to another holder of Class B Common Stock; and

(1)            the granting of a revocable proxy to officers or directors of the Corporation at the request of the Board of Directors of the Corporation in connection with actions to be taken at an annual or special meeting of stockholders;

(2)            entering into a voting trust, agreement or arrangement (with or without granting a proxy) solely with stockholders who are holders of Class B Common Stock that (a) is disclosed either in a Schedule 13D filed with the Securities and Exchange Commission or in writing to the Secretary of the Corporation, (b) either has a term not exceeding one (1) year or is terminable by the holder of the shares subject thereto at any time and (c) does not involve any payment of cash, securities, property or other consideration to the holder of the shares subject thereto other than the mutual promise to vote shares in a designated manner;

(3)            the pledge of shares of Class B Common Stock by a stockholder that creates a mere security interest in such shares pursuant to a bona fide loan or indebtedness transaction for so long as such stockholder continues to exercise Voting Control over such pledged shares; provided, however, that a foreclosure on such shares or other similar action by the pledgee shall constitute a Transfer unless such foreclosure or similar action qualifies as a Permitted Transfer;

(4)            the entering into, or reaching an agreement, arrangement or understanding regarding, a support, voting, tender or similar agreement or arrangement (with or without a proxy) in connection with a merger, sale or acquisition of assets, liquidation or other transaction approved by the Board of Directors;

(5)            due to the fact that the spouse of any holder of shares of Class B Common Stock possesses or obtains an interest in such holder’s shares of Class B Common Stock arising solely by reason of the application of the community property laws of any jurisdiction, so long as no other event or circumstance shall exist or have occurred that constitutes a “Transfer” of such shares of Class B Common Stock; provided that any transfer of shares by any holder of shares of Class B Common Stock to such holder’s spouse, including a transfer in connection with a divorce proceeding, domestic relations order or similar legal requirement, shall constitute a “Transfer” of such shares of Class B Common Stock unless otherwise exempt from the definition of Transfer; or

For purposes of this Article IV, Section 4.02(d)(ii), “Voting Control” shall mean, with respect to a share of Class B Common Stock, the power (whether exclusive or shared) to vote or direct the voting of such share by proxy, voting agreement or otherwise.

iii. Reservation of Class A Common Stock Issuable Upon Conversion. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of effecting the conversion of the shares of the Class B Common Stock, such number of its shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of such Class B Common Stock; and if at any time the number of authorized but unissued shares of Class A Common Stock shall not be sufficient to effect the conversion of all then-outstanding shares of such Class B Common Stock, in addition to such other remedies as shall be available to the holder of such Class B Common Stock, the Corporation will take such corporate action as may be necessary to increase its authorized but unissued shares of Class A Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in reasonable best efforts to obtain the requisite stockholder approval of any necessary amendment to this Certificate of Incorporation.

Section 4.03. Preferred Stock.

At each annual meeting of stockholders, beginning with the first annual meeting of stockholders following the effective date of this Certificate of Incorporation, directors elected to succeed those directors whose terms expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election. Notwithstanding the foregoing, the directors elected to each class shall hold office until their successors are duly elected and qualified or until their earlier resignation, death or removal.

Notwithstanding anything herein to the contrary and in addition to any vote required by law, (i) for so long as the holders of Class B Common Stock hold at least a majority in voting power of the outstanding shares of Common Stock, the affirmative vote of the holders of not less than a majority of the outstanding shares of capital stock of the Corporation entitled to vote thereon and (ii) if the holders of Class B Common Stock no longer hold at least a majority in voting power of the outstanding shares of Common Stock, the affirmative vote of the holders of not less than two thirds (2/3) in voting power of the outstanding shares of capital stock of the Corporation entitled to vote thereon, shall be required to amend or repeal any provision of this Article V, Section 5.02.

Except as otherwise required by law and subject to any rights of the holders of any series of Preferred Stock to elect directors under specified circumstances, any newly created directorships resulting from an increase in the authorized number of directors and any vacancies occurring in the Board of Directors may only be filled (and in the case of a newly created directorship, their class chosen) by the affirmative votes of a majority of the members of the Board of Directors, although less than a quorum, or by a sole remaining director. A director so elected to fill a newly created directorship resulting from an increase in the authorized number of directors shall serve until the next election of the class for which such director shall have been chosen and until a successor is duly elected and qualified, subject to such director’s earlier of such director’s death, resignation or removal. A director so elected to fill a vacancy shall be elected to hold office until the earlier of the expiration of the term of office of the director whom he or she has replaced and until a successor is duly elected and qualified, subject to such director’s earlier of such director’s death, resignation, or removal.

Section 5.04. Removal. Subject to any rights of the holders of any series of Preferred Stock, so long as the Board of Directors is classified pursuant to Section 5.02 or any successor provision (i) for so long as the holders of Class B Common Stock hold at least a majority in voting power of the outstanding shares of Common Stock, any director or the entire Board may be removed from office at any time, with or without cause, by the holders of a majority in voting power of the shares of capital stock of the Corporation then entitled to vote at an election of directors and (ii) if the holders of Class B Common Stock no longer hold at least a majority in voting power of the outstanding shares of Common Stock, any director or the entire Board may be removed from office at any time, but only for cause, by the holders of a majority in voting power of the shares of capital stock of the Corporation then entitled to vote at an election of directors.

Section 5.05 Preferred Stock Directors. During any period when the holders of one or more series of Preferred Stock have the separate right to elect additional directors as provided for or fixed pursuant to the provisions of Article IV, Section 4.03 hereof (including any certificate of designation) (a “Preferred Stock Director”), and upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such number of directors that the holders of any series of Preferred Stock have a right to elect, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions; and (ii) each Preferred Stock Director shall serve until such Preferred Stock Director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, disqualification or removal. Except as otherwise provided for or fixed pursuant to the provisions of Article IV, Section 4.03 hereof (including any certificate of designation), whenever the holders of one or more series of Preferred Stock having a separate right to elect additional directors cease to have or are otherwise divested of such right pursuant to said provisions, the terms of office of all Preferred Stock Directors elected by the holders of such series of Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such Preferred Stock Director shall cease to be qualified as a director and shall cease to be a director) and the total authorized number of directors of the Corporation shall be automatically reduced accordingly.

Section 5.06. Written Ballot. Unless and except to the extent that the Bylaws shall so require, the election of directors of the Corporation need not be by written ballot.

The Corporation shall not effect any Related Party Approval Transaction that has not been approved by the Related Party Transactions Committee. For purposes of this Certificate of Incorporation, “Independent Directors” shall mean any directors considered “independent” under the rules of the U.S. Securities and Exchange Commission and any exchange on which the securities of the Corporation are listed, including for purposes of Rule 10A-3 promulgated under the Securities Exchange Act of 1934, as amended (or any successor rule thereto) and who are determined by the Board to be independent of Michael Nieri.
