The Convertible Note was a result of an exchange agreement executed on February 8, 2024 in which the parties agreed to exchange the then outstanding promissory note into a convertible note in the principal amount of $4,849,491 convertible into Common Stock at the initial conversion price of $100.00 (the "Convertible Note"), subject to adjustment based on the effectiveness of the Company’s Reverse Stock Split which became effective on February 9, 2024. On February 16, 2024, the conversion price was adjusted downward to $62.64 pursuant to the terms of the Convertible Note. The conversion price was adjusted downward several times during the year due to down round trigger events that occurred (see below). On February 16, 2024, the Company received a notification from Alpha to convert $100,000 into 1,597 shares of common stock at an exercise price of $62.64, reducing the principal balance to $4,749,491.

The Company remitted the October and November 2024 monthly payments and the December 2024 payment was waived by the lender.

Convertible Note Conversion Price Adjustments During the year ended December 31 2025 and prior to repayment, the conversion price of the Convertible Note was reduced from $1.10 to $0.8294 due to the sale of Series F preferred stock and Series F warrants with a conversion price and exercise price of $0.8294 (see Note 9) which resulted in the reduction of the Convertible Note's conversion price. The Company recognized a loss on debt extinguishment of $125,242 for the incremental value of the conversion feature due to the reduced conversion price. The incremental value was determined using a Black-Scholes pricing model pre and post modification and the following inputs: expected term 0.50 years, risk free rate of 4.27%, volatility of 203.53%, and dividend rate of 0.00%. During the year ended December 31, 2024, the conversion price of the Convertible Note was reduced on March 6, August 27, and October 1, 2024 due to equity or equity-linked issuances or modifications which triggered reductions in the conversion price from $62.50 to $30.00 to $20.19 and to $4.00, respectively. Upon the conversion price reductions , the Company determined the incremental value using a Black-Scholes pricing model pre and post reduction and the following inputs: expected term 0.50 - 0.92 years, risk free rate of 3.96% - 4.83% , volatility of 89.6% - 130.57% and dividend rate of 0.00%.

The incremental value of $1,572,512 has been reflected on the statement of operations and comprehensive loss as a loss on debt extinguishment.
