funding and the cancellation of $1,506,000 aggregate principal amount of the 2019 12% Notes. The 15% Notes have an annual interest rate of 15% and matured on January 31, 2021. $1.0 million of the 15% Notes were exchanged for the 10% Notes (see above), $2.1 million was paid in full in December 2020 and the remaining $200,000 was paid in full in the three months ended March 31, 2021. The 15% Notes provide that they shall be repaid in full out of the proceeds of any new debt or equity capital raise with net proceeds of more than $5,000,000. In connection with the issuance of the 15% Notes, each holder of 15% Notes received three warrants (i.e., a 2020 A Warrant, a 2020 B Warrant and a 2020 C Warrant) to acquire shares of common stock at an exercise price equal to $0.45 per share, with the number of shares subject to each warrant equal to one share for each $1.00 of principal amount of 15% Notes issued to the noteholder. The 2020 A Warrants had an expiration date of December 31, 2020, the 2020 B Warrants have an expiration date of December 31, 2021, and the 2020 C Warrants have an expiration date of December 31, 2022 (collectively, the “15% Warrants”). By way of example, if an investor was issued a 15% Note with a principal amount of $250,000, such noteholder would receive a 2020 A Warrant to purchase 250,000 shares of common stock, a 2020 B Warrant to purchase 250,000 shares of common stock and a 2020 C Warrant to purchase 250,000 shares of common stock. Accordingly, as of March 31, 2020, the Company has issued 15% Warrants to purchase a total of 6,993,000 shares of common stock to the holders of 15% Notes. The exercise price of these warrants is subject to adjustment as a result of certain future equity issuances of securities by the Company at a price below the then-effective exercise price of the 15% Warrants. As a result of such subsequent issuances of securities by the Company during the second quarter of 2020, the exercise price of the 15% Warrants had decreased to $0.3983 per share. In December 2020, the warrant holders exercised 1,131,000 of the 2020 A Warrants into 282,813 shares of our common stock through cashless exercise.
We received $300,000 of cash in December 2019 and an additional $525,000 of cash January 2020 through March 2020 for issuing the 15% Notes. The relative fair value of the new funding on the 15% Warrants was recorded as a debt discount and additional paid-in capital of $333,056. The relative fair value of the cancellation of the outstanding indebtedness was recorded as an extinguishment of debt and additional paid-in capital of $668,335. For the three months ended March 31, 2021 and 2020, amortization of debt discount expense was $0 and $69,159, respectively, from the 15% Notes. The 15% Notes are otherwise treated as conventional debt.

NOTE 8. WARRANT DERIVATIVE LIABILITY
On May 31, 2019 we received gross proceeds of $3 million by issuing three million shares of our common stock and three million warrants (“2019 Warrants”) to purchase shares of our common stock (“2019 Units”) in a registered direct offering for $1.00 per 2019 Unit (collectively defined as the “2019 Capital Raise”). The 2019 Warrants, issued with the 2019 Capital Raise, are accounted for as a derivative liability. The 2019 Warrant agreements contain a cash settlement provision whereby the holders could settle the warrants for cash based on the Black-Scholes value, upon certain fundamental transactions, as defined in the 2019 Warrant agreement, that are considered outside of the control of management, such as a change of control. The original exercise price of the 2019 Warrants was $1.30 per share. The 2019 Warrants contain certain anti-dilution adjustment provisions with respect to subsequent issuances of securities by the Company at a price below the exercise price of such warrants. As a result of such subsequent issuances of securities by the Company during the fourth quarter 2019, the exercise price of the 2019 Warrants decreased to $0.45 per share and the number of shares subject to the 2019 Warrants increased to 8,666,666 shares of common stock as of December 31, 2019. In May 2020, we issued securities at a price lower than the $0.45 per share above. As a result, the exercise price of the 2019 Warrants decreased to $0.40 per share and the number of shares subject to the 2019 Warrants increased to 9,591,614 shares of common stock.
