        <footnote id="F1">These performance-based restricted stock units (&quot;PSUs&quot;) are subject to both performance and time vesting requirements. The number of PSUs reported represents the target number of PSUs under the award. The number of PSUs that vest, if any, may vary from 0% to 300% of the target number shown, and is based on criteria related to the annual total shareholder return of The Hain Celestial Group, Inc. (the &quot;Company&quot;) over the three-year period beginning on November 6, 2018. The time vesting requirement will be satisfied on November 6, 2021.</footnote>
        <footnote id="F2">Each PSU represents a contingent right to receive one share of common stock of the Company.</footnote>
        <footnote id="F3">These restricted stock units (&quot;RSUs&quot;) will vest in three (3) equal installments on April 14, 2020, 2021 and 2022.</footnote>
