Dividends on shares of our 1965 Series Preferred Stock are cumulative from the first day of the dividend period (as defined in our articles of incorporation) in which the stock was originally issued and will be paid, or declared and set apart for payment, before any dividends shall be declared or paid on or set apart for any class of stock ranking junior to the 1965 Series Preferred Stock as to dividends or assets, so that if, for any past dividend period, dividends or the current dividend period dividends on the 1965 Series Preferred Stock have not been paid, or declared and set apart for payment, the deficiency must be fully paid or declared and funds set apart for the payment of those dividends before any dividends will be declared or paid on or set apart for any class of stock ranking junior to the 1965 Series Preferred Stock as to dividends or assets.

No dividends may at any time be paid on or set apart for any share of 1965 Series Preferred Stock unless at the same time there is paid on or set apart for all shares of 1965 Series Preferred Stock then outstanding dividends in such amount that the holders of all shares of 1965 Series Preferred Stock will receive or have set apart for them a uniform percentage of the full annual dividend to which they are, respectively, entitled.
