        <footnote id="F1">These shares are vested shares resulting from the achievement of a share price milestone pursuant to a September 14, 2018 performance-based restricted stock unit grant (PRSU), comprising 12,431 shares granted to the reporting Person on September 14, 2018 and 646 shares granted to the reporting person in connection with a special dividend on April 12, 2021. The share price milestone of $11.77 was achieved on October 6, 2020 and, as a result, one-twelfth of the PRSU grant vested on such date and another one-twelfth vested on October 6, 2021, which was one-year following the achievement of such milestone.</footnote>
        <footnote id="F2">Represents shares of NATR common stock withheld to pay taxes upon vesting of performance-based restricted stock units, comprising 4,892 shares granted to the reporting Person on September 14, 2018 and 255 shares granted to the reporting person in connection with a special dividend on April 12, 2021. The number of shares withheld was determined on October 6, 2021, based on the closing price of NATR common stock on that date.</footnote>
        <footnote id="F3">These shares are in the form of performance-based restricted stock units (PRSUs). Each PRSU represents the right to receive one share of NATR common stock. The vesting of the PRSUs is contingent upon six growth rate milestones related to NATR's closing stock price that may be attained within a three-year performance period ending September 14, 2021. PRSUs vest in six equal installments in connection with achievement of the six following stock price milestones: $11.77; $14.48; $17.20; $19.91; $22.63; and $25.34.</footnote>
