entitling them to exercise two-thirds or any other proportion of the voting power of the corporation or of any class or classes of shares thereof, such action, unless expressly provided otherwise by statute, may be taken by the vote, consent, waiver or release of the holders of shares entitling them to exercise not less than a majority of the voting power of the corporation or of such class or classes.

EIGHTH: In each election of directors, each nominee who receives a majority of the votes cast with respect to such nominee’s election shall be elected as a director; provided, however, that if the election is contested or cumulative voting is in effect pursuant to the Articles and Section 1701.55 of the Ohio Revised Code, then the nominees receiving the greatest number of votes “for” the nominee’s election (up to the number of directors to be elected) shall be elected. For purposes of this Article EIGHTH, “a majority of the votes cast” means that the number of shares voted “for” a nominee’s election must exceed the number of shares voted “against” the nominee’s election, with abstentions and broker non-votes being disregarded. An election shall be considered “contested” if the number of nominees exceeds the number of directors to be elected in such election.

NINTH: No holder of shares of any class of the corporation shall have the right to vote cumulatively in the election of directors of the corporation.

TENTH: These amended and restated articles of incorporation supersede the articles of the corporation existing at the effective date of these amended and restated articles.
