Represents the 45,437 Class A ordinary shares, which may be acquired by Sponsor upon the conversion of 181,750 rights (included in the Sponsor's private placement units) upon consummation of the registrant's initial business combination. As described in the Registration Statement under the heading "Description of Securities-Share Rights," each right will automatically convert into one-fourth (1/4) of one Class A ordinary share upon consummation of the registrant's initial business combination, subject to certain adjustments described therein and have no expiration date. No fractional Class A ordinary shares will be issued upon conversion of such rights.

This amendment is being filed to correct an inadvertent typographical error in Table II original Form 4, filed June 9, 2026, in which the Ownership Form Codes were incorrectly listed as "Disposed Of" (D), rather than "Securities Acquired" (A). This amendment corrects such details in Table II to reflect the acquisition of securities.
