(i) the distinctive designation of the series, whether by number, letter or title, and the number of shares which will constitute the series, which number may be increased or decreased (but not below the number of shares then outstanding and except where otherwise provided in the applicable Preferred Stock Certificate of Designation) from time to time by action of the Board;

(ii) the dividend rate and the times of payment of dividends, if any, on the shares of the series, whether such dividends will be cumulative, and if so, from what date or dates, and the relation which such dividends, if any, shall bear to the dividends payable on any other class or classes of stock;

(iii) the price or prices at which, and the terms and conditions on which, the shares of the series may be redeemed at the option of the Corporation;

(iv) whether or not the shares of the series will be entitled to the benefit of a retirement or sinking fund to be applied to the purchase or redemption of such shares and, if so entitled, the amount of such fund and the terms and provisions relative to the operation thereof;

(v) whether or not the shares of the series will be convertible into, or exchangeable for, any other shares of stock of the Corporation or other securities, and if so convertible or exchangeable, the conversion price or prices, or the rates of exchange, and any adjustments thereof, at which such conversion or exchange may be made, and any other terms and conditions of such conversion or exchange;

(viii) whether the series will have voting rights, in addition to any voting rights provided by law, and, if so, the terms of such voting rights, which may provide, among other things and subject to the other provisions of this Certificate, that each share of such series shall carry one vote or more or less than one vote per share, that the holders of such series shall be entitled to vote on certain matters as a separate class (which for such purpose may be comprised of such series or of such series and one or more other series or classes of stock of the Corporation) and that all the shares of such series entitled to vote on a particular matter shall be deemed to be voted on such matter in the manner that a specified portion of the voting power of the shares of such series or separate class are voted on such matter; and

(ix) any other preferences, qualifications, privileges, options and other relative or special rights and limitations of that series.

(b) Voting Rights.

(c) Dividends. Holders of Preferred Stock shall be entitled to receive, when and as declared by the Board, out of funds legally available for the payment thereof, dividends at the rates fixed by the Board for the respective series, and no more, before any dividends shall be declared and paid, or set apart for payment, on Common Stock with respect to the same dividend period.

In the event of the voluntary or involuntary liquidation, dissolution or winding up of the Corporation, holders of each series of Preferred Stock will be entitled to receive the amount fixed for such series plus, in the case of any series on which dividends will have been determined by the Board to be cumulative, an amount equal to all dividends accumulated and unpaid thereon to the date of final distribution whether or not earned or declared before any distribution shall be paid, or set aside for payment, to holders of Common Stock. If the assets of the Corporation are not sufficient to pay such amounts in full, holders of all shares of Preferred Stock will participate in the distribution of assets ratably in proportion to the full amounts to which they are entitled or in such order or priority, if any, as will have been fixed in the resolution or resolutions providing for the issue of the series of Preferred Stock. Neither the merger nor consolidation of the Corporation into or with any other corporation, nor a sale, transfer or lease of all or part of its assets, will be deemed a liquidation, dissolution or winding up of the Corporation within the meaning of this paragraph except to the extent specifically provided for herein or in the applicable Preferred Stock Certificate of Designation.

(e) Redemption. The Corporation, at the option of the Board, may redeem all or part of the shares of any series of Preferred Stock on the terms and conditions fixed in the applicable Preferred Stock Certificate of Designation for such series.
