Series X Preferred Stock issuance for compensation

On November 5, 2026 the Board of Directors approved the issuance of additional shares of its Series X Preferred stock to its three (3) directors and one (1) existing holder as consideration for work on its acquisition matters. Mack Leath was issued an additional 4,800 shares bringing his total Series X Preferred holdings to 12,000 shares.

Anglo Irish Management, LLC was issued an additional 4,800 shares bringing their total holdings of Series X Preferred shares to 43,103 shares.

As a result of this issuance the Company now has 91,103 shares of its 10% Series X Cumulative Redeemable Perpetual Preferred Stock (the “Series X Preferred Stock”) outstanding. The Series X Preferred Stock has a par value of $0.01 per share, no stated maturity, a liquidation preference of $25.00 per share, and will not be subject to any sinking fund or mandatory redemption and will remain outstanding indefinitely unless the Company decides to redeem or otherwise repurchase the Series X Preferred Stock; the Series X Preferred Stock is not redeemable prior to November 4, 2020. The Series X Preferred Stock will rank senior to all classes of the Company’s common and preferred stock and accrues dividends at the rate of 10% per annum on $25.00 per share. Beginning in October 2024, the Company elected to use the closing stock price on the 15^th of each month to determine the number of shares to be issued in payment of the dividend. Each one share of the Series X Preferred Stock is entitled to 400 votes on all matters submitted to a vote of our shareholders, and as of the date of this filing the holders of its Series X Preferred shares have over 5% voting control of the Company’s stock.

As a result of these issuances the Board of Directors has sufficient shares votes in aggregate for approximately 25% of the share votes available, while Anglo Irish Management, LLC has approximately 24% of the share votes available. Five (5) of the holders, including a former Board member, have voting control for any matters requiring approval with over 54% of the votes available. When the other Series X Preferred holders are included the group made up of all Series X Preferred holders has in total voting rights for over 57% of the shares available to vote.
