While any shares of Preferred Stock are outstanding, we may not authorize the creation or issuance of any class or series of stock that ranks senior to the Preferred Stock as to dividends or amounts due upon liquidation, dissolution or winding up without the consent of the holders of 66 2/3% of the outstanding shares of Preferred Stock and any other series of preferred stock ranking on a parity with the Preferred Stock as to dividends and amounts due upon liquidation, dissolution or winding up, voting as a single class without regard to series.

Dividends

Preferred shareholders are entitled to receive, when, as and if declared by the Board of Directors out of our assets legally available therefore, cumulative cash dividends at the rate per annum of $3.50 per share of Preferred Stock.

Until the Preferred shareholders have been paid the Liquidation Preference in full, no payment will be made to any holder of Junior Stock upon our liquidation, dissolution or winding up. The term “junior stock” means our Common Stock and any other class of our capital stock issued and outstanding that ranks junior as to the payment of dividends or amounts payable upon liquidation, dissolution and winding up to the Preferred Stock.
