        <footnote id="F1">Mr. Code does not beneficially own any shares of common stock of the issuer. However, Mr. Code has a pecuniary interest in shares of Class B common stock through his ownership of membership interests of Legacy Acquisition Sponsor I LLC. As described in the issuer's registration statement on Form S-1 (File No. 333-221116) under the heading &quot;Description of Securities--Founder Shares&quot;, 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, 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.</footnote>
