What constitutes a Quorum at the Meeting?

A Quorum of shareholders is necessary to hold a valid meeting. The holders of at least one-third of the
Ordinary Shares entitled to vote as of the Record Date at the Meeting must be present, in person (including those who voted online) or by proxy (or, in the case of a holder that is a corporation or other
non-natural person, by its duly authorized representative or proxy), at the Meeting to constitute a “Quorum” and in order to conduct business at the Meeting. As of the Record Date,
12,220,834 Ordinary Shares would be required to achieve a Quorum at the Meeting.

Our Sponsor, and officers and directors collectively own 725,000 Class A Ordinary Shares and 7,187,500 Class B Ordinary Shares, or approximately 21.6% of our total issued and outstanding Ordinary Shares, which will count towards this Quorum.
