        <footnote id="F1">These shares are vested shares resulting from the achievement of a share price milestone pursuant to an April 1, 2020 performance-based restricted stock unit grant (PRSU). The shares vested upon achievement of the first $11.77 share price milestone over a period of 45-trading days. One-twelfth of the PRSU grant vests upon the achievement of each milestone and an additional one-twelfth vests on the date that is one-year following the achievement of such milestone subject to the recipient's continued employment.</footnote>
        <footnote id="F2">Represents shares of NATR common stock withheld to pay taxes upon vesting of performance-based restricted stock units originally granted to the Reporting Person on March 29, 2019. The number of shares withheld was determined on October 6, 2020, based on the closing price of NATR common stock on that date.</footnote>
        <footnote id="F3">Represents shares in the form of performance-based restricted stock units (PRSUs) that were incorrectly reported as having vested from an April 1, 2020 grant, but should have been reported as having vested from the March 29, 2019 PRSU grant.</footnote>
