Item 1.01 Entry Into a Definitive Material Agreement.

In May 2023, we made an offer to each holder of our Series B Common Stock Purchase Warrants dated June 30, 2021 to exchange those warrants for the issuance by us of a like number of shares of our Common Stock. Pursuant to this offer, the holders of an aggregate of 7,459,375 of these warrants agreed to the exchange. Included among the holders participating was Mr. Finkelstein, our President and CEO (56,250 warrants) and Aptafin S.p.A., an affiliate of us by share ownership (1,125,000 warrants).

On July 3, 2023, we sold and issued a $50,000 Convertible Promissory Note to Essetifin S.p.A., an affiliate of us by share ownership. This note accrues interest at a rate of 5% per annum and is due, if not earlier converted at the option of the holder to Common Stock, on June 11, 2028. Beginning six months after the initial note issuance, the principal and accrued interest on each note may be converted into shares of our Common Stock based on a conversion rate of $0.02 per share, subject to customary adjustments.

To induce Essetifin S.p.A. to lend funds to us, we also agreed to issue such investor a five-year warrant to purchase a number of shares of our Common Stock equal to 150% of the number of shares of Common Stock into which the purchased note could initially convert. The warrant is exercisable by the holder commencing six months after issuance at an exercise price of $0.02 per share, subject to customary adjustments.

The note and warrant we issued are in the same forms as those described in our report on Form 8-K dated June 13, 2023.

Item 3.02 Unregistered Sales of Equity Securities.

In May and June 2023, we exchanged an aggregate of 7,459,375 of our Series B Common Stock Purchase Warrants held by 22 individuals and entities for a like number of shares of our Common Stock. In exchanging the warrants for shares of our Common Stock, we relied on the exemption under Section 3(a)(9) of the Securities Act of 1933, as amended. No person or entity was paid or given any commission or other remuneration directly or indirectly for soliciting the exchange.

On July 3, 2023, we sold to one entity a $50,000 Convertible Promissory Note due on June 12, 2028. The principal and accrued interest on the note is convertible at the option of the holder beginning six months after issuance into shares of our Common Stock at a rate of $0.02 per share, subject to customary adjustments. In connection with the sale and issuance of this note, we issued this purchaser a five-year warrant to purchase (beginning six months after issuance) an aggregate of 3,750,000 shares of our Common Stock at an exercise price of $0.02 per share, subject to customary adjustments.

In selling and issuing the note and warrant, we relied on the exemption under Section 4(a)(2) of the Securities Act of 1933, as amended. The securities were sold in a private transaction to an entity that represented itself as an “accredited investor” and was acquiring the securities for investment, and we have noted the instruments representing the securities with restrictions on transfer unless in compliance with the Securities Act.

Item 8.01 Other Events.

On July 10, 2023, we began distributing a letter to stockholders describing the above warrant exchange and further explaining our rationale for seeking to terminate our reporting obligations under the Securities Exchange Act of 1934, as amended.
