        <footnote id="F1">Pursuant to the separation agreement dated August 6, 2020 by and between the Reporting Person, Assured Guaranty Ltd. (&quot;Issuer&quot;) and certain of Issuer's subsidiaries (such subsidiaries, together with Issuer, the &quot;Company&quot;), the Reporting Person agreed to transfer to the Issuer on December 31, 2020 (or as soon as reasonably practicable thereafter) common shares of Issuer, par value $0.01 per share (&quot;Common Shares&quot;), with a value equal to $12,000,000 in substitution of the Reporting Person's existing obligation to deliver $24,000,000 of interests in certain investment vehicles to the Company under the terms of the Reporting Person's employment agreement dated August 7, 2019 with the Company.</footnote>
        <footnote id="F2">The price per share of the Common Shares transferred to Issuer will be determined based on the volume weighted average trade price per Common Share on the New York Stock Exchange (&quot;NYSE&quot;) (calculated to the nearest one-hundredth of a cent) for the first 10 NYSE trading days in the month of December 2020. In the event that $12,000,000 exceeds the value of the Common Shares held by the Reporting Person and transferred to Issuer, the Reporting Person has agreed to pay to the Company an amount in cash equal to the excess of $12,000,000 over the value of the Common Shares transferred to Issuer (with the price per share of such Common Shares measured in accordance with the above).</footnote>
