Item 4 — Purpose of Transaction
Item 4 is hereby amended to add the following: On June 30, 2026, Six Thirty AI purchased in a private placement 16,700 shares of the Issuer's Series D Convertible Preferred Stock ("Series D") with funds borrowed by Six Thirty AI from YA II PN, LTD, an investor otherwise unaffiliated with the Issuer. Six Thirty AI has the right to convert the Series D into Shares within 60 days of the date of this Amendment No. 10 to Schedule 13D. The Series D and underlying Shares are pledged to YA II PN, LTD pursuant to a Loan and Guaranty Agreement dated June 30, 2026, and related agreement, and the Series D are exchangeable for the borrowed funds. The Conversion Price floats (95% of lowest daily VWAP in the five trading days prior to notice of conversion, with a floor price of $1.80 (20% of the closing price immediately prior to the initial closing), but there is a 19.99% cap on conversion until shareholder approval is obtained. The floating Conversion Price is otherwise subject to the terms and conditions established in the Certificate of Designations for the Series D Convertible Preferred Stock. Assuming the daily VWAP of a Share as of June 30, 2026 ($8.81) is used to calculate the Conversion Price, the Series D Convertible Preferred Stock would convert into 1,995,221 Shares.
