| 1. On September 30, 2026, the Issuer issued a convertible promissory note (the "Note") in the principal amount of $250,000.00 to Yorkville Acquisition Sponsor II, LLC (the "Sponsor"), in order to provide the Issuer with additional working capital. All amounts due under the Note may be converted into 25,000 units. Each unit consists of one Class A ordinary share ("Ordinary Share") and one-half of one warrant to purchase one Ordinary Share, resulting in 25,000 Ordinary Shares and warrants to purchase 12,500 Ordinary Shares of the Issuer upon the consummation of the business combination. The warrants shall have the same terms and conditions as the warrants issued in the Issuer's initial public offering. |
| 2. The principal balance of the Note shall be payable by the Issuer on the earlier of the date on which the Issuer consummates its initial business combination or the date that the winding up of the Issuer is effective, and is convertible at the Sponsor's election upon the consummation of the initial business combination. |
