to obtain or maintain the listing of the combined company’s Class A common stock on the New York Stock Exchange, as applicable,
following the Business Combination; (4) the risk that the Business Combination disrupts current plans and operations as a result

Business Combination, which may be affected by, among other things, competition and the ability of the combined company to grow
and manage growth profitably and retain its key employees; (6) costs related to the Business Combination; (7) changes in applicable
laws or regulations; (8) the inability of the combined company to raise financing in the future; (8) the success, cost and timing
