US Convertible Debenture 2 (Navy Capital Green Fund)

Convertible debenture in the principal amount of $1,000,000 (the “U.S. Convertible Debenture 2”) dated October 31, 2018, which bears interest, payable quarterly, at a rate of 8% per annum, with interest during the first eighteen months following issuance being payable by increasing the then-outstanding principal amount of the U.S. Convertible Debenture 2. The U.S. Convertible Debenture 2 was to mature on a date that was three years following issuance. The U.S. Convertible Debenture 2 was convertible into Convertible Debenture Units at a conversion price of $3.20 per Convertible Debenture Unit. Each Convertible Debenture Unit consisted of (i) one share of the Company’s common stock, and (ii) one-half of one warrant, with each warrant exercisable for three years to purchase a share of common stock at a price of $4.40.

On July 26, 2019, U.S. Convertible Debenture 2 was amended such that, should the Company issue or sell common stock or equity securities convertible into common stock at a price less than the conversion price of the U.S. convertible Debenture 2, the conversion price of U.S. Convertible Debenture 2 would be reduced to such issuance price, and the exercise price of the warrant issuable in connection with U.S. Convertible Debenture 2 would be exercisable at a price equal to 137.5% of the adjusted conversion price at the time of conversion. The U.S. Convertible Debenture 2 has other features, such as mandatory conversion in the event the common stock trades at a particular price over a specified period of time and required redemption in the event of a “Change in Control” of the Company. The U.S. Convertible Debenture 2 is an unsecured obligation of the Company and ranks pari passu in right of payment of principal and interest with all other unsecured obligations of the Company. The Company recorded a discount in the amount of $813,724 on the U.S. Convertible Debenture 2.

On April 15, 2021, the U.S. Convertible Debenture 2 was amended as follows: (i) the conversion price of the debentures was reduced to $1.20 per unit; and (ii) the maturity date was extended from October 31, 2021 to October 31, 2022. This amendment was accounted for as an extinguishment of debt, and the Company recorded a loss in the amount of $509,700 during the year ended May 31, 2021.

On September 15, 2022, the U.S. Convertible Debenture 2 was amended as follows: (i) the conversion price of debentures with a principal amount of $675,668 was reduced to $0.285 per unit, and these debentures along with accrued interest in the amount of $11,261 were converted to 2,410,279 shares of common stock and warrants to purchase 1,205,140 shares of common stock; (ii) the conversion price of the remaining debentures with a principal amount of $450,446 was reduced to $0.40 per share; (iii) the maturity date of 50% of the remaining debentures with a principal amount of $225,223 was extended to December 31, 2023, and the maturity date of 50% of the remaining debentures with a principal amount of $225,223 was extended to December 31, 2024; and (iv) the conversion price of the warrants issuable upon conversion of the debentures was reduced to $0.40. The value of the warrants will be determined when the issuance becomes probable, which the Company believes is unlikely to occur until the conversion price of the debentures is below the market price of the Company’s common stock. This amendment was accounted for as an extinguishment of debt, and a loss in the amount of $422,331 was recorded on this transaction. The fair values of the warrants and conversion options included in the calculation of the loss on extinguishment of debt were $223,515 and $198,816, respectively.
