        <footnote id="F2">Under the Reporting Person's arrangement with Apple Tree Venture Management, LLC (the &quot;Management Company&quot;), the Reporting Person holds the option for the benefit of Apple Tree Partners IV, L.P. (the &quot;Fund&quot;). The Reporting Person is obligated to turn over to the Management Company any net cash received upon exercise of the option and sale of the underlying common stock, which will offset management fees owed by the Fund to the Management Company. The Reporting Person therefore disclaims beneficial ownership of the option and underlying common stock.</footnote>
