Series D Preferred Stock

In connection with the Spin-Off Distribution, Tankers Family Inc., a corporation all of whose outstanding common shares are owned by the Lax Trust, an irrevocable trust established for the benefit of certain family members of Mr. Evangelos J. Pistiolis, received 100,000 shares of Series D Preferred Stock of the Issuer ("Series D Preferred Stock"). One share of Series D Preferred Stock has the voting power of 1,000 Common Shares. In order to satisfy the minimum percentage of voting of Mr. Evangelos J.

Pistiolis or any related parties affiliated with Mr. Evangelos J. Pistiolis and the Lax Trust does not fall below a majority of our total voting power, irrespective of any new common or preferred stock issuances. Both the number of the Series D Preferred Shares and the votes per Series D Preferred Share are not adjusted in case of splits, subdivisions, reverse stock splits or combinations of the Issuer's outstanding Common Shares. Shares of the Series D Preferred Stock are not convertible into Common Shares and have no dividend or other economic rights. The foregoing description of the Series D Preferred Stock is subject to and qualified in its entirety by reference to the Statement of Designations of the Series D Preferred Stock, which is incorporated by reference herein.
