        <footnote id="F1">On July 29, 2019, the Reporting Person was granted 24,090 restricted stock units (&quot;RSUs&quot;), for which the Reporting Person is entitled to receive one (1) share of Common Stock for each RSU upon vesting. The RSUs were scheduled to vest in two (2) equal annual installments beginning July 29, 2020.  The vesting of the RSUs was accelerated in full on December 11, 2019 in connection with the pending transactions contemplated by the Agreement and Plan of Merger entered into on November 10, 2019 among the Issuer, Foamix Pharmaceuticals Ltd and Giants Merger Subsidiary Ltd., a wholly-owned subsidiary of the Issuer, in order to mitigate potential negative tax consequences to both the Issuer and the Reporting Person under Section 280G and 4999 of the Internal Revenue Code.</footnote>
