share (the Class A Common Stock), upon the exercise of warrants (the Public Warrants) originally sold as part of units, consisting of one share of Class A Common Stock and

The selling stockholders may offer, sell or distribute all or a portion of their shares of Class A Common Stock publicly or through
private transactions at prevailing market prices or at negotiated prices. Although we will receive the exercise price of the Private Placement Warrants and the Forward Purchase Warrants if those warrants are not exercised on a cashless basis, we
will not receive any of the proceeds from the sale of the shares of Class A Common Stock owned by the selling stockholders. We will bear all costs, expenses and fees in connection with the registration of these shares of Class A Common
Stock, including with regard to compliance with state securities or blue sky laws. The selling stockholders will bear all commissions and discounts, if any, attributable to their sale of shares of Class A Common Stock. See
