exercised. If the over-allotment option is exercised after the date of the prospectus, we will file an amendment to the Form 8-K or a
new Form 8-K to provide updated financial information to reflect the exercise of the over-allotment option. We will also include in the
Form 8-K, or amendment thereto, or in a subsequent Form 8-K, information indicating if the underwriters has allowed separate trading of
the Ordinary Shares and Warrants prior to the 52nd day after the date of the prospectus.
