Subject to the prior rights of all classes or series of stock at the time outstanding having prior rights as to dividends or other distributions, the holders of shares of Common Stock shall be entitled to receive such dividends and other distributions in cash, property, or stock as may be declared on the Common Stock by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor and shall share equally on a per share basis in all such dividends and other distributions.

one or more series or classes and to fix for each such series or class (i) the number of shares constituting such series or class and the designation of such series or class, (ii) the voting powers (if any), whether full or limited, of the shares of such series or class, (iii) the powers, preferences, and relative, participating, optional or other special rights of the shares of each such series or class, and (iv) the qualifications, limitations, and restrictions thereof, and to cause to be filed with the Secretary of State of the State of Delaware a certificate of designation with respect thereto. Without limiting the generality of the foregoing, to the fullest extent as may now or hereafter be permitted by the DGCL, the authority of the Board of Directors with respect to the Preferred Stock and any series or class thereof shall include, but not be limited to, determination of the following:

(a) the number of shares constituting any series or class, which number the Board of Directors may thereafter increase or decrease (but not below the number of shares thereof then outstanding) and the distinctive designation of that series or class;

(b) the dividend rate or rates on the shares of any series or class, the terms and conditions upon which and the periods in respect of which dividends shall be payable, whether dividends shall be cumulative and, if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of that series or class;

(c) whether any series or class shall have voting rights, in addition to the voting rights provided by applicable law, and, if so, the number of votes per share and the terms and conditions of such voting rights;

The powers, preferences and relative, participating, optional and other special rights of the shares of each series or class of Preferred Stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series or classes at any time outstanding. Unless otherwise provided in the resolution or resolutions providing for the issuance of such series or class of Preferred Stock, shares of Preferred Stock, regardless of series or class, which shall be issued and thereafter acquired by the Corporation through purchase, redemption, exchange,

conversion or otherwise shall return to the status of authorized but unissued Preferred Stock, without designation as to series or class of Preferred Stock, and the Corporation shall have the right to reissue such shares.
