        <footnote id="F1">Explanatory Note: This amended Form 3 is being filed to correct the Form 3 filed on September 2, 2021 (the &quot;Original Form 3&quot;), which inadvertently did not report shares of Class A Common Stock held by the reporting person's spouse. All other information previously reported in the Original Form 3, and restated in this amended Form 3, remains correct.</footnote>
