Convertible debentures payable in the aggregate principal amount of $12,012,000 (the “Canaccord Debentures”) dated December 12, 2018, which bear 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 Canaccord Debentures. The Canaccord Debentures were to mature on a date that was three years following issuance. The Canaccord Debentures were 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. The Canaccord Debentures have 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 Canaccord Debentures are unsecured obligations of the Company and rank pari passu in right of payment of principal and interest with all other unsecured obligations of the Company. During the three months ended November 30, 2019, in two separate transactions, principal in the aggregate amount of $25,857 was converted into an aggregate of 8,081 shares of the Company’s common stock, and warrants to purchase 4,040 shares of common stock. There were no gains or losses recorded on these conversions because they were done in accordance with the terms of the original agreement. No discount was recorded for the fair value of the warrants issued. Because the market price of the Company’s common stock was less than the conversion price on the date of issuance of the Canaccord Debentures, a discount was not recorded on the Canaccord Debentures. During the three and six months ended November 30, 2022, the Company accrued interest in the amounts of $131,628 and $396,011 on the Canaccord Debentures, respectively. During the three and six months ended November 30, 2022, the Company made interest payments in the amounts of $0 and $264,383, respectively. On March 31, 2021, the Canaccord Debentures were amended as follows: (i) the conversion price of the debentures was reduced to $1.20 per unit; (ii) the maturity date was extended from December 12, 2021 to December 12, 2022; (iii) the mandatory conversion threshold was reduced from a daily volume weighted average trading price of greater than $4.80 per share to $2.40 per share for the preceding ten consecutive trading days; and (iv) the exercise price of the warrants issuable upon conversion was reduced from $4.40 to $1.60 and the expiration of the warrants extended until March 31, 2024. This amendment was accounted for as an extinguishment of debt, and the Company recorded a loss in the amount of $3,286,012 during the year ended May 31, 2021. During the year ended May 31, 2022, principal in the aggregate amount of $281,000 was converted into an aggregate of 234,167 shares of the Company’s common stock, and warrants to purchase 117,084 shares of common stock. There were no gains or losses recorded on these conversions because they were done in accordance with the terms of the original agreement. On September 15, 2022, the Canaccord Debentures were further amended as follows: (i) the conversion price of debentures with a principal amount of $7,965,278 was reduced to $0.285 per unit, and these debentures along with accrued interest in the amount of $132,755 were converted to 28,414,149 shares of common stock and warrants to purchase 14,207,075 shares of common stock; (ii) the conversion price of the remaining debentures with a principal amount of $52,53,873 was reduced to $0.40 per share; (iii) the maturity date of 50% of the remaining debentures with a principal amount of $2,626,936.50 was extended to December 31, 2023, and the maturity date of 50% of the remaining debentures with a principal amount of $2,626,936.50 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. This amendment was accounted for as an extinguishment of debt, and a loss in the amount of $4,547,660 was recorded on this transaction.
