Each whole warrant entitles the holder to purchase one Ordinary Share at an exercise price of $11.50 per Ordinary Share; and 

The Purchaser has agreed to purchase an aggregate of 7,880,000 warrants (or up to 8,900,000 warrants depending on the extent to which the
underwriters in the Public Offering exercise their over-allotment option) (the “Sponsor Warrants”), each Sponsor Warrant entitling the holder to purchase one Ordinary Share at an exercise price of $11.50 per Ordinary Share.
