Warrants


During the year ended December 31, 2020, the Company issued warrants to purchase 10,608,750 shares of the Company’s common stock as part of the Public Offering (see Note 8 – Underwritten Public Offering) and to the note holders that extended the due date of their unsecured promissory notes (see Note 10 – Amendments to Notes and Warrants) and warrants to purchase 2,365,595 shares of the Company’s common stock as part of the Private Offering that converted outstanding amounts due under the Company’s 8% Unsecured Promissory Notes due 2021 (see Note 7 - Notes Payable).


During the year ended December 31, 2020, the Company entered into amendments (the “Amendments”) with certain holders of the Company’s 8% Unsecured Promissory Notes (the “2018 Notes”) and Nontransferable Common Stock Purchase Warrants (the “2018 Warrants”). Pursuant to the Amendments, the maturity date of the applicable 2018 Notes was extended from March 29, 2021 to June 30, 2021 and the expiration date of the applicable 2018 Warrants was extended from March 29, 2021 to March 29, 2022. The terms of the applicable 2018 Notes were also amended to grant the holders of such 2018 Notes a right to participate in a future private offering of the Company’s securities upon terms substantially similar to those offered to investors in a future primary offering of the Company’s securities and to grant resale registration rights in connection therewith. The Company recognized $209,810 of non-cash costs in Other Expenses in the accompanying statements of operations relating to the 2018 Warrants extension.


The Company subsequently entered into a second amendment to the 2018 Notes with certain holders whereby the maturity date of the applicable 2018 Notes was extended from June 30, 2021 to June 30, 2022 and the expiration date of the applicable 2018 Warrants was extended from March 29, 2022 to March 29, 2026. The exercise price of the 2018 Warrants was adjusted from $5.30 per share to $2.00 per share. The terms of the applicable 2018 Notes were also amended to require that the holders of such 2018 Notes participate in a future private offering of the Company’s securities upon terms substantially similar to those offered to investors in a future primary offering of the Company’s securities (see Note 7 – Notes Payable). The Company also granted an additional warrant to purchase 0.5 of one share of its common stock, or 1,511,250 shares of common stock in total, per dollar of each participating 2018 Note holder’s principal amount of the 2018 Notes with an exercise price of $2.00 per share and an expiration date of March 29, 2026 (the “New Warrants”). The New Warrants will be exercisable beginning on the six-month anniversary of the date of issuance, and the Company granted to the participating 2018 Note holders certain registration rights with respect to its securities issued in the Private Offering and the shares of common stock underlying the New Warrants. The Company recognized $489,645 of non-cash costs in Other Expenses in the accompanying statements of operations related to this second amendment.


Also, during the year ended December 31, 2020, the Company entered into amendments with certain holders of the Company’s Common Stock Purchase Warrants (the “2017 Warrants”) pursuant to which the expiration date of the applicable 2017 Warrants was extended from June 30, 2020 to September 30, 2021. The Company recognized $1,591,233 of non-cash costs in Other Expenses in the accompanying statements of operations relating to the 2017 Warrants extension.


The Company determined the proper classification of the loan modification based on ASC 470-50, Debt Modifications and Extinguishments. Because the change in present value of cash flows of the modified debt is less than 10% when compared to the present value of the cash flows of the original debt, no change is required to be made to the debt in the accompanying condensed financial statements.


During the year ended December 31, 2020, warrants to purchase 20,000 shares of common stock were exercised for cash proceeds of $45,000.


During the year ended December 31, 2019, warrants to purchase 50,000 shares of the Company’s common stock were exercised for cash proceeds of $57,500.
