(4)           (A)          Dividend, Subdivision, Combination or Reclassification of Common Stock.  In the event that the Corporation shall at any time or from time to time, prior to conversion of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A (w) pay a dividend or make a distribution on the outstanding shares of Common Stock payable in capital stock of the Corporation, (x) subdivide the outstanding shares of Common Stock into a larger number of shares, (y) combine the outstanding shares of Common Stock into a smaller number of shares or (z) issue any shares of its capital stock in a reclassification of the Common Stock (other than any such event for which an adjustment is made pursuant to another clause of this paragraph (d)(4)), then, and in each such case, the Conversion Rate in effect immediately prior to such event shall be adjusted (and any other appropriate actions shall be taken by the Corporation) so that the holder of any share of 6% Mandatory Convertible Cumulative Preferred Stock, Series A thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock or other securities of the Corporation that such holder would have owned or would have been entitled to receive upon or by reason of any of the events described above, had such share of 6% Mandatory Convertible Cumulative Preferred Stock, Series A been converted immediately prior to the occurrence of such event.  An adjustment made pursuant to this paragraph (d)(4)(A) shall become effective retroactively (x) in the case of any such dividend or distribution, to a date immediately following the close of business on the record date for the determination of holders of Common Stock entitled to receive such dividend or distribution or (y) in the case of any such subdivision, combination or reclassification, to the close of business on the day upon which such corporate action becomes effective.

(B)          Certain Distributions.  In case the Corporation shall at any time or from time to time, prior to conversion of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A, distribute to all holders of shares of the Common Stock (including any such distribution made in connection with a merger or consolidation in which the Corporation is the resulting or surviving entity and the Common Stock is not changed or exchanged) cash, evidences of indebtedness of the Corporation or another issuer, securities of the Corporation or another issuer or other assets (excluding cash dividends in which holders of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A participate; dividends payable in shares of Common Stock for which adjustment is made under another subparagraph of this paragraph (d); or the issuance by another entity of capital stock in consideration of an acquisition that also provides adequate consideration to the holders of 6% Mandatory Convertible Cumulative Preferred Stock, Series A approved by the Board of Directors) or rights or warrants to subscribe for or purchase of any of the foregoing, then, and in each such case, the Conversion Rate then in effect shall be adjusted (and any other appropriate actions shall be taken by the Corporation) by multiplying the Conversion Rate in effect immediately prior to the date of such distribution by a fraction (x) the denominator of which shall be the then current market price of the Common Stock immediately prior to the date of distribution less the then fair market value (as determined by the Board of Directors in the exercise of their fiduciary duties) of the portion of the cash, evidences of indebtedness, securities or other assets so distributed or of such rights or warrants

6

applicable to one share of Common Stock and (y) the numerator of which shall be the then current market price of the Common Stock immediately prior to the date of distribution (but such fraction shall not be applicable with respect to any distribution of rights or warrants to subscribe for or purchase securities of the Corporation if the holder of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A would otherwise be entitled to receive such rights or warrants upon conversion at any time of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A into Common Stock.  Such adjustment shall be made whenever any such distribution is made and shall become effective retroactively to a date immediately following the close of business on the record date for the determination of shareholders entitled to receive such distribution.

(5)           Abandonment.  If the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, and shall thereafter and before the distribution to shareholders thereof legally abandon its plan to pay or deliver such dividend or distribution, then no adjustment in the Conversion Rate shall be required by reason of the taking of such record.

(6)           Certificate as to Adjustments.  Upon any adjustment in the Conversion Rate, the Corporation shall maintain a detailed record of any and all such adjustments setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated and specifying the increased or decreased Conversion Rate then in effect following such adjustment.

(7)           Reorganization, Reclassification.  In case of any merger or consolidation of the Corporation or any capital reorganization, reclassification or other change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value) (each, a “Transaction”), the holder of each share of 6% Mandatory Convertible Cumulative Preferred Stock, Series A shall have the right to receive in such Transaction, in exchange for each share of 6% Mandatory Convertible Cumulative Preferred Stock, Series A, a security identical to (and not less favorable than) the 6% Mandatory Convertible Cumulative Preferred Stock, Series A, and provision shall be made therefor in the agreement, if any, relating to such Transaction.

(8)           Reservation of Common Stock.  The Corporation shall at all times reserve and keep available for issuance upon the conversion of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A, such number of its authorized but unissued shares of Common Stock as will from time to time be sufficient to permit the conversion of all outstanding shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A, and shall take all action to increase the authorized number of shares of Common Stock if at any time there shall be insufficient authorized but unissued shares of Common Stock to permit such reservation or to permit the conversion of all outstanding

If, upon such liquidation, dissolution or winding up, the assets thus distributed among the holders of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A shall be insufficient to permit the payment to such shareholders of the full preferential amounts aforesaid, then the entire assets of the Corporation to be distributed shall be distributed ratably among the holders of shares of 6% Mandatory Convertible Cumulative Preferred Stock, Series A.
