(3) Authority is hereby granted to the Board of Directors to create one or more series of Preferred Stock and, with respect to each series, to fix by resolution or resolutions providing for the issue of such series: (a) The number of shares to constitute such series and the distinctive designation thereof; (b) The dividend rate on the shares of such series, the dividend payment dates, the periods in respect of which dividends are payable ("Dividend Periods"), whether such dividends shall be cumulative, and, if cumulative, the date or dates from which dividends shall accumulate; (c) Whether or not the shares of such series shall be redeemable, and, if redeemable, on what terms, including the redemption prices which the shares of such series shall be entitled to receive upon the redemption thereof; (d) Whether or not the shares of such series shall be subject to the operation of retirement or sinking funds to be applied to the purchase or redemption of such 8 shares for retirement and, if such retirement or sinking funds be established, the annual amount thereof and the terms and provisions relative to the operation thereof; (e) Whether or not the shares of such series shall be convertible into, or exchangeable for, shares of any other class or classes or of any other series of the same or any other class or classes of stock of the Corporation and the conversion price or prices or rate or rates, or the rate or rates at which exchange shall be made, with such adjustments, if any, as shall be stated and expressed or provided in such resolution or resolutions; (f) The preferences, if any, and the amounts thereof which the shares of such series shall be entitled to receive upon the voluntary and involuntary dissolution of the Corporation; (g) The voting power, if any, of the shares of such series; and (h) Such other terms, conditions, specifications, special rates and protective provisions as the Board of Directors may deem advisable. Notwithstanding the fixing of the number of shares constituting a particular series upon the issuance thereof, the Board of Directors may at any time thereafter authorize the issuance of additional shares of the same series, unless the resolution of the Board of Directors providing for such series shall expressly prohibit the issuance of additional shares of such series. (4) No dividend shall be declared and set apart for payment on any series of Preferred Stock in respect of any Dividend Period unless there shall likewise be or have been paid, or declared and set apart for payment, on all shares of Preferred Stock of each other series entitled to cumulative dividends at the time outstanding which rank equally or prior as to dividends with the series in question, dividends ratably in accordance with the sums which would be payable on the said shares through the end of the last preceding Dividend Period if all dividends were declared and paid in full. (5) If upon any dissolution of the Corporation, the assets of the Corporation distributable among the holders of any one or more series of Preferred Stock which (i) are entitled to 9 a preference over the holders of the Common Stock upon such dissolution, and (ii) rank equally in connection with any such distribution, shall be insufficient to pay in full the preferential amount to which the holders of such shares shall be entitled, then such assets, or the proceeds thereof, shall be distributed among the holders of each such series of the Preferred Stock ratably in accordance with the sums which would be payable on such distribution if all sums payable were discharged in full. (6) In the event that the Preferred Stock of any series shall be redeemable, then, at the option of the Board of Directors, the Corporation may at such time or times as may be specified by the Board of Directors as provided in subparagraph (c) of paragraph 3 of this Article IV redeem all, or any number less than all, of the outstanding shares of such series at the redemption price thereof and on the other terms fixed by the Board of Directors as provided in said subparagraph (c). COMMON STOCK (7) Subject to all of the rights of the Preferred Stock, dividends may be paid upon the Common Stock as and when declared by the Board of Directors, out of any funds legally available therefor. (8) Upon any liquidation, dissolution or winding up of the Corporation, and after the holders of the Preferred Stock of each series shall have been paid in full the amounts to which they respectively shall be entitled, as provided in the resolution of the Board of Directors creating such series, or an amount sufficient to pay the aggregate amount to which the holders of the Preferred Stock of each series shall be entitled, as provided in the resolution of the Board of Directors creating such series, shall have been deposited with a bank or trust company designated by the Board of Directors having a capital, surplus and undivided profits of at least Five Million Dollars ($5,000,000) as a trust fund for the benefit of the holders of such Preferred Stock, the remaining net assets of the Corporation shall be distributed pro rata to the holders of the Common Stock. (9) The holders of Common Stock shall be entitled to one vote for each share of such stock held by them. If the By- 10 Laws so provide, the election of directors need not be by ballot. Subject to voting rights, if any, provided to the holders of any series of Preferred Stock in the resolution of the Board of Directors providing for the issue of such series of Preferred Stock, the holders of Common Stock shall have the exclusive power to vote on all matters coming before the stockholders of the Corporation. GENERAL (10) If it seems desirable so to do, the Board of Directors may from time to time issue scrip for fractional shares of stock. Such scrip shall not confer upon the holder any voting or other rights of a stockholder of the Corporation, but the Corporation shall from time to time, within such time as the Board of Directors may determine, issue one whole share of stock upon the surrender of scrip for fractional shares aggregating one whole share, properly endorsed if in registered form. (11) No holder of stock of the Corporation shall be entitled as such, as a matter of right, to subscribe for or purchase any part of any new or additional issue of stock of any class whatsoever, or of securities convertible into stock of any class whatsoever, whether now or hereafter authorized or whether issued for cash, for a consideration other than cash or by way of dividend. (12) The Corporation shall be entitled to treat the person in whose name any share is registered as the owner thereof, for all purposes, and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not the Corporation shall have notice thereof, save as expressly provided by the laws of the State of Delaware. 11 V.

No director of this Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except that this paragraph shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to this Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law or (iv) for any transaction from which the director derived an improper personal benefit.
