Notwithstanding the foregoing, whenever the holders of any one or more classes or series of preferred stock issued by the Corporation shall have the right, voting separately by class or series, to elect directors at an annual or special meeting of Shareholders, the election, term of office, filling of vacancies and other features

5

of such directorships shall be governed by the terms of this Restated Certificate of Incorporation applicable thereto.

5.                                        The term “Continuing Director” shall mean a director who either (i) was a member of the Board of Directors of the Corporation immediately prior to the time that the Related Person involved in a Business Combination became a Related Person, or (ii) has been designated (before his or her initial election as director) as  a Continuing Director by a majority of the then Continuing Directors.

6.                                        A “Related Person” shall be deemed to have acquired a share of the capital stock of the Corporation at the time when such Related Person became a Beneficial Owner thereof.  With respect to the shares owned by Affiliates, Associates or other persons whose ownership is aggregated with that of a Related Person under the foregoing definition of Related Person, if the price paid by such Related Person for such shares is not determinable by the Continuing Directors, such price shall be deemed to be the higher of (i) the price paid upon the acquisition thereof by the Affiliate, Associate or other person or (ii) the market price of the shares in question at the time when the Related Person became a Beneficial Owner thereof.

II.                                      The Board of Directors of the Corporation shall have the power and duty to determine for the purposes of this Article Eighth on the basis of information then known to it, (i) whether any person is an Affiliate or Associate of another person, (ii) whether any proposed sale, lease, exchange or other disposition of part of the properties or assets of the Corporation involves a Substantial Part of the properties or assets of the Corporation and (iii) the value of the Highest Per Share Price and Highest Equivalent Price.  Any such reasonable determination by the Board shall be conclusive and binding for all purposes of this Article Eighth.

III.                                  Any amendment, change or repeal of this Article Eighth, or any other amendment of this Restated Certificate of Incorporation which will have the effect of modifying or permitting circumvention of this Article Eighth, shall require the favorable vote, at a meeting of the Shareholders of the Corporation, of (a) the holders of at least 75% of the then outstanding shares of capital stock of the Corporation entitled to vote and (b) a majority of the outstanding shares of capital stock of the Corporation entitled to vote of which a Related Person is not a Beneficial Owner; provided, however, that this Paragraph III shall not apply to, and such 75% and majority vote shall not be required for, any such amendment, change or repeal recommended to Shareholders by the affirmative vote of not less than three-fourths of the Continuing Directors, and such amendment, change, or repeal so recommended shall require only the vote, if any, required under the applicable provision of the General Corporation Law of the State of Delaware.
