Simultaneously with the closing of the IPO, the Company consummated a private placement (the “Private Placement”) of an aggregate of 683,000 units (the “Private Units”) to the Sponsor and BTIG, LLC, the representative of the underwriters in the IPO (“BTIG”), at a price of $10.00 per Private Unit, generating total proceeds of $6,830,000. Each Private Unit consists of one Class A Ordinary Share and one-half of one redeemable Warrant, with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share (subject to adjustment). Of those 683,000 Private Units, the Sponsor purchased 430,000 Private Units and BTIG purchased 253,000 Private Units.
