In connection with the Domestication, Leo Investors III LP's (the &quot;Sponsor&quot;) Class B ordinary shares, par value $0.0001 per share, of Leo, which were previously convertible into Class A ordinary shares of Leo, were automatically converted into shares of Class A common stock of Local Bounti, par value $0.0001 per share, on a one-for-one basis.</footnote>
        <footnote id="F2">Pursuant to the Private Placement Warrant Purchase Agreement, dated as of February 25, 2021, by and between Leo and the Sponsor, the Sponsor purchased warrants to purchase Class A ordinary shares, which following the Domestication entitle the Sponsor to purchase shares of Class A common stock of Local Bounti (the &quot;Private Placement Warrants&quot;) for a price of $1.50 per Private Placement Warrant. Pursuant to the Warrant Agreement, dated March 2, 2021 (as amended on November 19, 2021), by and between Leo and Continental Stock Transfer &amp; Trust Company, upon consummation of the Business Combination, the Private Placement Warrants became exercisable, beginning 30 days after the closing of the Business Combination, for one share of Class A common stock at a price of $11.50 per share. The Private Placement Warrants expire on the fifth anniversary of the consummation of the Business Combination.</footnote>
