Each unit was sold at a public offering price of $5.60. The Class C and Class D Warrants are immediately exercisable at a price of $5.60 per share. The Class C and Class D warrants each have a cashless exercise provision entitling the holders to surrender one Class C Warrant and receive 0.4 shares of common stock and on the surrender of one Class D Warrant the holder is entitled to receive 0.8 shares of common stock. The Class C Warrants expire five years from the date of issuance and the Class D Warrants expire three years from the date of issuance. The shares of common stock (or pre-funded warrants in lieu thereof) and accompanying warrants were only purchasable together in this offering but were issued separately and were immediately separable upon issuance. In addition, the company issued a total of 86,000 common stock warrants to the placement agent, Maxim Group, and the Company’s financial advisor, Ascendiant Capital. Gross proceeds, before deducting offering expenses, totaled approximately $12.0 million. Of the $12.0 million of gross proceeds, approximately $5.4 million were allocated to common stock and prefunded warrants ($4.8 million net of offering costs) and approximately $6.7 million were allocated to derivative liabilities (with approximately $0.7 million of cash offering costs and $0.1 million of agent warrant offering costs recorded as derivative expense).

2021 Equity Distribution Agreement

On February 25, 2021, the Company entered into an Equity Distribution Agreement (as amended, the “2021 Distribution Agreement”) with Maxim Group LLC (“Maxim”), pursuant to which the Company may sell from time to time, shares of the Company’s common stock having an aggregate offering price of up to $2.0 million through Maxim, as agent. Subject to the terms and conditions of the 2021 Distribution Agreement, as amended, Maxim will use its commercially reasonable efforts to sell the shares from time to time, based on our instructions. Under the 2021 Distribution Agreement, Maxim may sell the Shares by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including, without limitation, sales made directly on the Nasdaq Capital Market. We have no obligation to sell any shares under the ATM and may at any time suspend offers under the 2021 Distribution Agreement. The Offering will terminate upon the earlier of (i) the sale of shares having an aggregate offering price of $15.0 million, (ii) the termination by either Maxim or the Company upon the provision of fifteen (15) days written notice, or (iii) February 25, 2024. Under the terms of the 2021 Distribution Agreement, Maxim will be entitled to a transaction fee at a fixed rate of 2.0% of the gross sales price of Shares sold under the 2021 Distribution Agreement. The Company will also reimburse Maxim for certain expenses incurred in connection with the 2021 Distribution Agreement and agreed to provide indemnification and contribution to Maxim with respect to certain liabilities under the Securities Act and the Securities Exchange Act of 1934, as amended. As of March 31, 2023, there have been no sales of shares of common stock under the 2021 Distribution Agreement. Because the company’s public float is less than $75 million, we may not sell securities over a 12-month period in an amount greater than one-third of our public float. In connection with the February 2023 offering, the Company agreed to not make any sales of securities under the ATM for a period of six months from the date of closing the offering, February 10, 2023, until August 10, 2023.
