In addition, this prospectus relates to the issuance by us of up to 236,019 shares of our Class A Common Stock issuable upon exercise of warrants as follows: ●1,036 shares of Class A Common Stock issuable upon the exercise of up to 4,532,405 Public Warrants (as defined below),which were originally issued in the initial public offering of units of the Company at a price of $1,750.00 per unit, with eachunit consisting of one share of Class A Common Stock and one-half of one Public Warrant. Following anti-dilutionadjustments made in connection with the Business Combination, the Public Warrants have an exercise price of $0.4375 pershare. Because the exercise price of the Public Warrants is only $0.4375 per share, we believe holders of the Public Warrantswill likely exercise their Public Warrants. However, given the low exercise price, we would only receive nominal proceeds(less than $500) therefrom. ●234,983 shares of Class A Common Stock issuable upon the exercise of up to 1,028,046,326 New Warrants (as definedbelow), which were originally distributed to stockholders of the Company without charge as a dividend pursuant to the termsof the Business Combination. The New Warrants have an exercise price of $50,312.50 per share. The exercise price of theNew Warrants are highly dependent on the price of our Class A Common Stock and the spread between the exercise price ofthe New Warrants and the price of our Common Stock at the time of exercise. If the market price for our Class A CommonStock is less than $50,312.50 per share, we believe warrant holders will be unlikely to exercise their New Warrants. The lastreported sale price of the Class A Common Stock, as indicated below, is currently significantly below the $50,312.50 pershare exerc
