On January 30, 2023, in order to increase the number of shares available for issuance by the Issuer in a public offering of common stock, the Issuer entered into an exchange agreement (the “Exchange Agreement”) with Stammtisch, pursuant to which Stammtisch exchanged a total of 12,000,000 shares of Common Stock for 12,000,000 warrants, each exercisable to purchase one share of the Issuer’s Common Stock at an exercise price of $0.00001 per share of Common Stock (the “Exchange Warrants”).
