All shares of Preferred Stock shall be identical except in respect of particulars which may be fixed by the Board of Directors as hereinafter provided pursuant to authority which is hereby expressly vested in the Board of Directors. Each share of a series shall be identical in all respects with all other shares of such series, except as to the date from which dividends thereon shall be cumulative on any series as to which dividends are cumulative.

(2) In case the corporation shall not pay in full all dividends required to be paid on all shares of all series of cumulative Preferred Stock at the time outstanding to the full extent of the preference, if any to which each such cumulative series is entitled, all cumulative series which are of equal rank with respect to such dividend preference shall share ratably in the payment of dividends, including accumulations thereof, if any, in proportion to the amounts that would be payable on such series if all dividends thereof were paid in full. Accumulations of dividends shall not bear interest. (3) After the requirements with respect to preferential dividends (if any) upon all classes of capital stock, and each series thereof, shall have been met, then and not otherwise, the holders of Common Stock shall be entitled to receive such dividends, out of any remaining net profits or net assets of the corporation available there for, when, as and if (subject to the foregoing provisions of this article 4) such dividends may be declared from time to time by the Board of Directors.

In the absence of actual fraud in the transaction, the judgment of the Directors as to the consideration for the issuance of any such convertible security, warrant, right, privilege or option and the sufficiency thereof shall be conclusive. The conversion price, or other consideration to be received by the corporation upon the issuance of shares of capital stock upon the exercise of any such rights to convert, warrant, right, privilege or option shall have a value not less than the par value of the stock so issued, as determined by the Board of Directors. 5.
