Preliminary Note

Capitalized terms used in this Preliminary Note without definition have the meanings ascribed to them elsewhere in this Schedule 13D. 

Securities Holdings Resulting in Current Beneficial Ownership of Shares

As of the date hereof: (i) the Trust holds 1,637,956 Shares; (ii) the Foundation holds 33,999 Shares; (iii) the Trust holds 160,392 Common Stock Warrants (the “2017 Warrants”), issued on July 7, 2017 and expiring on January 7, 2024, each of which is currently exercisable to purchase 1/40th of a Share, for a total of up to 4,009 Shares; (iv) the Trust holds 3,155 Series B Warrants (the “2019 Series B Warrants”), issued on November 19, 2019 and expiring on May 19, 2027, each of which is currently exercisable to purchase 125 Shares, for a total of up to 394,375 Shares; and (v) the Trust holds 765,000 Common Stock Warrants (the “August 2023 Warrants”), issued on August 15, 2023 and expiring on August 15, 2028, each of which is currently exercisable to purchase one Share, for a total of up to 765,000 Shares.

The 2017 Warrants, the 2019 Series B Warrants and the August 2023 Warrants (together, the “Exercisable Warrants”) are exercisable within 60 days of the date hereof.  Accordingly, pursuant to Rule 13d-3(d) under the Exchange Act, the Trust currently is deemed to have beneficial ownership of the aggregate 1,163,384 Shares acquirable upon exercise of the Exercisable Warrants held by the Trust.

Securities Holdings Not Resulting in Current Beneficial Ownership of Shares

In addition, the Trust holds 335,570 Common Stock Warrants (the “May 2023 Warrants”), issued on May 5, 2023 and expiring on November 6, 2028, each of which becomes exercisable (subject to the Beneficial Ownership Limitation) on November 6, 2023 to purchase one Share.

The terms of the May 2023 Warrants provide that May 2023 Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Exchange Act, more than 9.99% (or, at the election of the holder and after 61 days’ advance notice to the Issuer, 19.99%) of the Shares then issued and outstanding (the “Beneficial Ownership Limitation”).  As of the date hereof, the Beneficial Ownership Limitation (which, as applied to the Reporting Persons, is 9.99% as of the date of the filing of this Amendment) does not permit the Trust to exercise any portion of the May 2023 Warrants.  In providing the beneficial ownership information set forth herein, the Reporting Persons have assumed that the aggregate 335,570 May 2023 Warrants held by the Trust are not exercisable due to the Beneficial Ownership Limitation.

As used herein, the term “August 2023 Offering” refers to the Issuer’s registered offering which, as disclosed by the Issuer in its Form 8-K filed with the SEC on August 11, 2023, entailed the issuance and sale by the Issuer of an aggregate 5,750,000 units, each consisting of (i) one Share and (ii) one August 2023 Warrant.
