        <footnote id="F1">These shares are in the form of restricted stock units (RSUs). Each RSU represents the right to receive one share of NATR common stock. These RSUs vest in three equal annual installments beginning on February 12, 2019.</footnote>
        <footnote id="F2">Due to a clerical error, a prior Form 4 for the Reporting Person set forth an incorrect number of shares directly owned by the Reporting Person. This Form 4 corrects the error and presents the correct number of shares directly owned by the Reporting Person. No intervening events have occurred to impact the number of shares directly owned.</footnote>
