        <footnote id="F1">Represents shares of common stock (each, a &quot;Share&quot;), par value $0.01 per share, of Perspecta Inc. (the &quot;Company&quot;) that are subject to performance-based restricted stock units (&quot;PSUs&quot;).  Pursuant to the Agreement and Plan of Merger (the &quot;Merger Agreement&quot;), among the Company, Jaguar ParentCo Inc. (&quot;Parent&quot;) and Jaguar Merger Sub Inc. (&quot;Merger Sub&quot;), on May 6, 2021, Merger Sub merged with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of Parent (the &quot;Merger&quot;).  Pursuant to the Merger Agreement, each PSU outstanding immediately prior to the consummation of the Merger became fully vested, for each PSU granted in fiscal 2019, at maximum performance and, for any other PSU, at target performance, and was canceled and converted into the right to receive, for each Share subject to such then-vested PSU, $29.35 in cash without interest and less any applicable tax withholdings.</footnote>
        <footnote id="F2">Pursuant to the Merger Agreement, at the effective time of the Merger, each Share was canceled and converted into the right to receive $29.35 in cash without interest and less any applicable tax withholdings.</footnote>
