DIVIDENDS.

The term "class of capital stock of the Corporation ranking junior to the Class B Stock" as used in this Certificate of Incorporation shall mean the Common Stock and any other class of stock of the corporation hereafter authorized which ranks junior to the Class B Stock as to payment of dividends or the distribution of assets upon dissolution, liquidation or winding-up. 4. REDEMPTION. The shares of Class B Stock of any series then outstanding shall be redeemable, in whole or in part, at the option of the Corporation, by resolution of its Board of Directors at such price or prices and at such time or times as may be fixed and determined by the Board of Directors in accordance with any resolution providing for the issuance of any such series of Class B Stock. In case of redemption of a part only of the shares of Class B Stock of any series at the time outstanding, the redemption may be either pro rata or by lot, as determined by the Board of Directors. Subject to the foregoing the Board of Directors shall have full authority and power to prescribe the manner in which the drawing by lot or the pro rata redemption shall be conducted and the terms and conditions upon which the shares of Class B Stock shall be redeemed from time to time. Notice of every redemption of shares of Class B Stock shall be given by mailing such notice, postage prepaid, not less than 10 nor more than 20 days prior to the date fixed for such redemption to each holder of record of shares so to be redeemed at his address as the same shall appear on the books of the Corporation. Each such notice shall specify the date fixed for redemption and the place where payment of the redemption price is to be made upon surrender for cancellation of the certificates representing shares called for redemption. Any notice which was mailed in the manner herein provided shall be conclusively presumed to be duly given whether or not the holder receives the notice. -4- <Page> If notice of redemption shall have been duly given as hereinabove provided, on and after the date fixed for redemption (unless the Corporation shall default in making payment of the redemption price), all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares, including, but not limited to, the right to receive dividends thereon, shall cease and terminate, notwithstanding that any certificate for such shares so called for redemption shall not have been surrendered for cancellation, and the holders of such shares so called for redemption shall cease to be shareholders and shall have no interest in or claim against the Corporation except the right to receive the redemption price upon surrender of their certificates for cancellation. Any resolution of the Board of Directors calling shares of any series of Class B Stock for redemption may provide to the extent permitted by applicable law that the shares so redeemed may have the status of treasury stock 5. REACQUIRED SHARES. Shares of any series of Class B Stock which have been acquired by the Corporation, whether by purchase or redemption or by their having been converted into or exchanged for other shares of the Corporation shall upon their acquisition and without any other action by the Corporation resume the status of authorized but unissued shares of Class B Stock and may be reissued as shares of the series of which they were originally a part or may be issued as shares of a new series or as shares of any other series. 6. VOTING RIGHTS. Except as otherwise provided in this Certificate of Incorporation, or as otherwise expressly provided by law, or as stated in the resolution or resolutions providing for the issue of such shares adopted by the board of directors pursuant to the authority hereby vested in it, the holders of shares of Class B Stock of any series shall not have any right to vote for the election of directors or for any other purpose, and the holders of shares of Class B Stock of any series shall not be entitled to any notice of any meeting of shareholders. 7. DISSOLUTION, LIQUIDATION OR WINDING-UP. In the event of any dissolution, liquidation or winding-up of the affairs of the Corporation, after payment or provision for payment of the debts or other liabilities of the Corporation, the holders of all then outstanding shares of Class B Stock shall be entitled to receive, before any distribution is made to any class of capital stock of the Corporation -5- <Page> ranking junior to the Class B Stock, out of the net assets of the Corporation; an amount in cash for each share equal to the amount fixed and determined by the Board of Directors in any resolution providing for the issuance of any such series of Class B Stock. If upon any dissolution, liquidation or winding-up of the affairs of the Corporation, the net assets available for distribution shall be insufficient to pay the holders of all outstanding shares of Class B Stock in full amounts to which they respectively shall be entitled, the holders of all outstanding shares of class B Stock of all series shall, before any distribution is made to any class of capital stock of the Corporation ranking junior to the Class B Stock, share ratably in any distribution of assets in accordance with the sums which would be payable upon such distribution if all sums payable were paid in full. Neither the merger nor the consolidation of the Corporation, nor the sale, lease or conveyance of all or a part of its assets, shall be deemed to be a liquidation or winding-up of the affairs of the Corporation within the meaning of this Article Fourth. 8. COMMON STOCK 1. DIVIDENDS. Subject to the preferential rights of the Class B Stock, the holders of shares of Common Stock shall be entitled to receive, when and if declared by the Board of Directors, out of the assets of the Corporation which are by law available therefor, dividends payable either in cash, in property, or in shares of Common Stock. 2. VOTING RIGHTS. Subject to the provisions of any applicable law, or of the by-laws of the corporation as from time to time amended, with respect to the closing of the transfer books or the fixing of a record date for the determination of stockholders entitled to vote and except as otherwise provided by law or by this Certificate of Incorporation, or by the resolution or resolutions providing for the issue of any series of Class B Stock, the holders of outstanding shares of Common Stock shall exclusively possess voting power for the election of directors and for all other purposes, each holder of record of shares of Common Stock being entitled to one vote in person or by proxy for each share of Common Stock standing in his name on the books of the Corporation. -6- <Page> 3.
