("Sponsor") directly owns 6,740,000 Class B ordinary shares, par value $0.0001 per share (the "Class B Shares"), of the Issuer, including 900,000 shares that are subject to forfeiture if the underwriters of the Issuer's initial public offering do not exercise in full an option granted to them to cover over-allotments. Pursuant to the Amended and Restated Memorandum and Articles of Association of the Issuer, such Class B Shares will automatically convert into Class A ordinary shares, par value $0.0001 per share, of the Issuer at the time of the Issuer's initial business combination on a one-for-one basis, subject to adjustment, and have no expiration date.
2. The sole shareholder of Sponsor is Avista Acquisition, LLC ("Avista Acquisiton"). Thompson Dean and David Burgstahler are the managers of Avista Acquisition (and, together with Sponsor, Messrs. Dean and Burgstahler are the "Reporting Persons").
