        <footnote id="F1">A Form 3 was previously jointly filed by the Reporting Person, IXII BV and Mr. Schuurman (the &quot;Reporting Group&quot;) on October 4, 2018 with respect to the Reporting Group's ownership of ordinary shares of the Issuer (the &quot;Subject Securities&quot;). At the time of such filing, Mr. Schuurman was the controlling shareholder of the Reporting Person and IXII BV and held sole voting and dispositive voting power with respect to the Subject Securities, and the Reporting Person beneficially owned over 10% of the Issuer's then current total outstanding amount of Subject Securities. Following the filing of such Form 3, the Reporting Person's individual beneficial ownership dropped below 10% of the Issuer's then current total outstanding amount of Subject Securities.</footnote>
        <footnote id="F2">(Continued from Footnote 1) This Form 3 is filed because the Reporting Person acquired all of the Subject Securities held by IXII BV by means of a merger between IXII BV and the Reporting Person (the &quot;Merger&quot;) whereby the Reporting Person survived the Merger and once again owned over 10% of the Issuer's Subject Securities and continues to be controlled by Mr. Schuurman who holds sole voting and dispositive power with respect to these Subject Securities.</footnote>
