        <footnote id="F2">On 12/31/16, Flamel Technologies S.A. (&quot;Flamel&quot;) merged with and into Avadel Pharmaceuticals plc (&quot;Avadel&quot;).  As a result of the Merger, Flamel's outstanding ordinary shares were cancelled and exchanged on a 1-for-1 basis for newly issued ordinary shares of Avadel, and all outstanding American Depositary Shares (ADSs) representing Flamel ordinary shares  were cancelled and exchanged on a 1-for-1 basis for ADSs representing Avadel ordinary shares.  The reporting person filed a Form 4 solely to report dispositions of Flamel securities as a result of the Merger, and filed a Form 3 to reflect the reporting person's new status as a director and/or executive officer of Avadel. This Form 4 reports the reporting person's acquisition of the same number and type of securities of Avadel in the Merger.  The reporting person made no market sales or purchases in connection with the dispositions reported in the Form 4 referenced above or the acquisitions reported in this Form 4.</footnote>
