The 225,000 Class A Ordinary Shares are included in units (each unit consisting of one Class A Ordinary Share and one right to receive one twentieth (1/20) of a Class A ordinary share upon the consummation of an initial business combination), acquired pursuant to a Private Placement Units Purchase Agreement by and between Jena Acquisition Sponsor LLC II (the "Sponsor") and the Issuer.

(2) The Sponsor is the record holder of the shares reported herein. Mr. William P. Foley II controls 54% of the membership interests in the Sponsor through Bilcar Limited Partnership, a Florida limited partnership ("Bilcar"), in which Mr. Foley and his wife are the only limited partners, and which Bilcar is the managing member of the Sponsor. The general partner of Bilcar is Bognor Regis Inc., a Florida corporation, in which Mr. Foley is the sole shareholder and president. Therefore Mr. Foley may be deemed to beneficially own the 225,000 Class A ordinary shares and 5,720,000 Class B ordinary shares, and ultimately exercise voting and dispositive power over the Class A ordinary shares and Class B ordinary shares held by the Sponsor. Mr. Foley disclaims beneficial ownership of these shares except to the extent of any pecuniary interest therein.

Insider Letter Agreement

On May 28, 2025, in connection with the IPO, the Issuer, the Sponsor and certain other parties thereto entered into a letter agreement (the "Insider Letter"). Pursuant to the Insider Letter, the Sponsor and the Issuer's officers and directors agreed (A) to vote their Founder Shares, any Ordinary Shares underlying the Placement Units and any public shares in favor of any proposed business combination, except that it or he shall not vote any Class A Ordinary Shares that it or he purchased after the Issuer publicly announces its intention to engage in such proposed business combination for or against such proposed business combination, (B) not to propose an amendment to the Issuer's Amended and Restated Memorandum and Articles of Association (i) that would modify the substance or timing of the Issuer's obligation to redeem 100% of the public shares if the Issuer does not consummate a business combination within 24 months after the closing of the Public Offering, or (ii) with respect to any other provision relating to the rights of holders of Class A Ordinary Shares or pre-initial business combination activity, unless the Issuer provides the holders of public shares with the opportunity to redeem such shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Issuer's trust account set up in connection with the IPO (the "Trust Account") including interest earned on the funds held in the Trust Account and net of taxes payable, divided by the number of then outstanding public shares, (C) not to redeem any Ordinary Shares in connection with a shareholder vote to approve the Issuer's proposed initial business combination or a vote to amend the provisions of the Issuer's Amended and Restated Memorandum and Articles of Association relating to shareholders' rights or pre-business combination activity and (D) that the Founder Shares and any Ordinary Shares underlying the Placement Units shall not participate in any liquidating distribution upon winding up if a business combination is not consummated. The Sponsor also agreed that, in the event of the liquidation of the Trust Account of the Issuer, it will indemnify and hold harmless the Issuer against any and all loss, liability, claims, damage and expense whatsoever which the Issuer may become subject to as a result of any claim by any vendor or other person (other than the Company's independent public accountants) who is owed money by the Issuer for services rendered or products sold to or contracted for the Issuer, or by any target business with which the Issuer has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Account below (i) $10.00 per public share or (ii) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of taxes payable, if any; provided that such indemnity shall not apply if such vendor or prospective target business executes an agreement waiving any claims against the Trust Account. The description of the Insider Letter is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.5 to the Form 8-K filed by the Issuer with the SEC on May 30, 2025 (and is incorporated by reference herein as Exhibit 10.3).
