The Company previously filed a registration statement on Form S-1, which was declared effective by the SEC on September 3, 2024 (SEC File No. 333-281755) (the "Form S-1") that covered the resale of up to 10,679,758 shares of Common Stock pursuant to the Purchase Agreement. The 10,679,758 shares of Common Stock represented (i) 10,574,018 shares issuable to Seven Knots, from time to time from and after the Commencement Date (as defined in the Purchase Agreement) upon the terms and subject to the conditions and limitations of the Purchase Agreement, and subject to the Exchange Cap (as defined below) (the "Initial Purchase Shares"); and (ii) 105,740 shares that were issuable upon the conversion of the outstanding unpaid principal balance, together with all accrued and unpaid interest of a commitment note issued to Seven Knots as consideration for its execution and delivery of the Purchase Agreement (the "Note Shares").
Pursuant to certain rules of the Nasdaq Stock Market LLC ("Nasdaq"), the Company was prohibited from issuing to Seven Knots under the Purchase Agreement more than 19.99% of the Common Stock below the "Minimum Price" (as determined in accordance with Nasdaq rules) (the "Exchange Cap"), until the Company obtained stockholder approval to issue shares of Common Stock in excess of the Exchange Cap in accordance with applicable Nasdaq rules (the "Stockholder Approval").
