Explanation of Responses:

1. As described in the issuer's registration statement on Form S-1 (File No. 333-222137) under the heading "Description of Securities--Founder Shares", the shares of Class B common stock will automatically convert into shares of Class A common stock at the time of the issuer's initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and certain anti-dilution rights and has no expiration date.

2. As contemplated in connection with the initial public offering of the issuer, 312,500 shares of Class B common stock of the issuer were returned by Nebula Holdings, LLC to the issuer for no consideration and cancelled because the underwriters' over-allotment option was not exercised in full.

3. On January 16, 2018, the reporting persons filed a Form 4, which mistakenly reported that they beneficially owned an aggregate of 6,875,000 shares of Class B common stock of the issuer subsequent to the transactions reported therein. The reporting persons owned an aggregate of 6,775,000 shares of Class B common stock of the issuer as of January 16, 2018 and such number remains unchanged as of the date hereof.
