(e) The term "Continuing Director" shall mean a Director who is unaffiliated with any Related Person and either (i) was a member of the Board of Directors of the Corporation immediately prior to the time the Related Person involved in a Business Combination became a Related Person or (ii) was designated (before his or her initial election or appointment as Director) as a Continuing Director by a majority of the then Continuing Directors. (f) The terms "Highest Per Share Price" and "Highest Equivalent Price" as used in this Article XIV shall mean the following: if there is only one class of capital stock of the Corporation issued and outstanding, the Highest Per Share Price shall mean the highest price that can be determined to have been paid at any time by the Related Person for any share or shares of that class of capital stock. If there is more than one class of capital stock of the Corporation issued and outstanding, the Highest Equivalent Price shall mean with respect to each class and series of capital stock of the Corporation, the amount determined by a majority of the Continuing Directors, on whatever basis they believe is appropriate, to be the highest per share price equivalent of the Highest Per Share Price that can be determined to have been paid at any time by the Related Person for any share or shares of any class or series of capital stock of the Corporation. In determining the Highest Per Share Price and Highest Equivalent Price, all purchases by the Related Person shall be taken into account regardless of whether the shares were purchased before or after the Related Person became a Related Person. Also, the Highest Per Share Price and the Highest Equivalent Price shall include any brokerage commissions, transfer taxes, soliciting dealers' fees and other expenses paid by the Related Person with respect to the shares of capital stock of the Corporation acquired by the Related Person.

The determinations of the Continuing Directors as to Fair Market Value, Highest Per Share Price, Highest Equivalent Price, and the existence of a Related Person or a Business Combination shall be conclusive and binding. 4. Nothing contained in this Article XIV shall be construed to relieve any Related Person from any fiduciary obligation imposed by law. 5. The fact that any Business Combination complies with the provisions of paragraph 1(b) of this Article XIV shall not be construed to impose any fiduciary duty, obligation or responsibility on the Board of Directors, or any member thereof, to approve such Business Combination or recommend its adoption or approval to the stockholders of the Corporation, nor shall such compliance limit, prohibit or otherwise restrict in any manner the Board of Directors, or any member thereof, with respect to evaluations of or actions and responses taken with respect to such Business Combination. 6. Notwithstanding any other provisions of these Articles of Incorporation or the Bylaws of the Corporation, the affirmative vote of the holders of not less than eighty percent of the outstanding shares of capital stock shall be required to amend, alter, change or repeal, or adopt any provisions inconsistent with, this Article XIV. The foregoing Restated Articles of Incorporation correctly set forth without change the corresponding provisions of the Restated Articles of Incorporation as previously amended and supersede the Restated Articles of Incorporation as amended.
