        <footnote id="F1">The Class B ordinary shares reported herein are convertible for the Issuer's Class A ordinary shares as described under the heading &quot;Description of Securities&quot; in the Issuer's Registration Statement filed on Form S-1 (File No. 333-294983) (the &quot;Registration Statement&quot;) and have no expiration date. The Class B ordinary shares reported herein include up to 825,000 Class B ordinary shares subject to forfeiture to the Issuer depending on the extent to which the underwriters' over-allotment option is exercised in connection with the Issuer's initial public offering of units, as described in the Registration Statement.</footnote>
        <footnote id="F2">Irenic Sponsor, LLC (the &quot;Sponsor&quot;) is the record holder of the shares reported herein. Adam Katz, the Issuer's Chief Executive Officer and a director, Matthew Kupersmith, the Issuer's Chief Financial Officer, and E-Fei Wang, the Issuer's President and a director, are the managers of the Sponsor. Irenic Capital Evergreen Master Fund LP (the &quot;Evergreen Fund&quot;), is the majority owner of the interests in the Sponsor. Mr. Katz shares control of Irenic Capital Evergreen Fund GP LLC, the general partner of the Evergreen Fund. Due to his indirect ownership in Evergreen Fund, Mr. Katz is deemed to have pecuniary interest in the shares held by Sponsor, despite a lack of beneficial ownership over Sponsor.</footnote>
        <footnote id="F3">In the Sponsor, each manager has one vote, and the approval of a majority is required to approve an action. Under the so-called &quot;rule of three,&quot; if voting and dispositive decisions regarding an entity's securities are made by three or more individuals, and voting or dispositive decisions require the approval of a majority of those individuals, then none of the individuals is deemed a beneficial owner of the entity's securities. Based on the foregoing, no individual manager of the Sponsor exercises voting or dispositive control over any of the securities held by the entity, even those in which he holds a pecuniary interest. Accordingly, none of the managers is deemed to have or share beneficial ownership of such shares. Each of Messrs. Katz, Kupersmith and Wang and the Evergreen Fund disclaims any beneficial ownership of the securities held by the Sponsor other than to the extent of any pecuniary interest that he or it may have therein, directly or indirectly.</footnote>
