        <footnote id="F2">These shares are held by George L. and Coleen M. Ball, Trustees of the George L. and Coleen M. Ball Family Trust UA 01-18-2005 (the &quot;Trust&quot;).  Mr. Ball has shared voting, investment and dispositive power over the shares held by the Trust.</footnote>
        <footnote id="F3">On April 15, 2019, Issuer's board of directors declared a common stock dividend, payable to all holders of record of common stock on May 9, 2019, of two shares of common stock for every one share of common stock outstanding, conditioned upon the closing of Issuer's initial public offering.  As a result, Reporting Person's account under the Parsons Corporation Employee Stock Ownership Plan (the &quot;ESOP&quot;) was credited with an additional 38,742 shares of common stock on May 10, 2019, the date of the closing of Issuer's initial public offering.</footnote>
