In accordance with the terms of the underwriting agreement entered into in connection with the Public Offering, the underwriters forfeited any rights or claims to the Deferred Discount because the Company was unable to consummate an initial business combination by the November 7, 2019 deadline under its Charter. Following the redemption of the Public Shares, the conversion of the Public Warrants and the forfeiture of the Private Placement Warrants, there were no Units, Public Shares, Public Warrants or Private Placement Warrants outstanding.
