During the quarter ended March 31, 2026, we issued
an aggregate of 13,750 shares of our Series A Convertible Preferred Stock in a private placement to institutional investors for gross
proceeds of $10,000,000 pursuant to a Securities Purchase Agreement entered into in February 2026. The shares were issued in reliance
on the exemption from registration provided by Section 4(a)(2) of the Securities Act and/or Rule 506 of Regulation D. The investors are
accredited and represented their investment intent; no general solicitation or advertising was used.
In January 2026, we issued 26,333 shares of common
stock as incentive shares to investors in connection with a short-term debenture financing, and 21,525 shares of common stock to certain
lenders pursuant to exchange agreements that converted outstanding subscription agreement loans and accrued interest into equity. We also
issued 202 “true-up” shares of common stock to Arena under our equity line of credit commitment fee. These issuances were
made in private transactions exempt from registration under Section 4(a)(2) of the Securities Act and/or Rule 506 of Regulation D.
We did not repurchase any of our equity securities
during the quarter ended March 31, 2026. There were no proceeds used from a registered offering during the period.
