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.
