        <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 monthly installments from the initial grant date through May 5, 2017.</footnote>
        <footnote id="F2">Prescott Capital holds indirectly 1,865,383 shares of Common Stock of Nature's Sunshine Products, Inc. through the account of the Master Fund of which the Prescott Capital is the Investment Manager. The Master Fund holds the shares of Common Stock for the accounts of the Small Cap Funds, for which Prescott Capital is the Investment Manager. Prescott Capital receives a portion of the profits in the form of a capital allocation from and owns a partnership interest in the Small Cap Funds. Mr. Watkins reports the shares held indirectly by Prescott Capital because, as the president of Prescott Capital, he may be deemed to beneficially own, and to have shared voting and dispositive power over, such shares.</footnote>
        <footnote id="F3">The filing of this Form 4 shall not be construed as an admission that Prescott Group Capital Management, L.L.C. (&quot;Prescott Capital&quot;) or Jeffrey D. Watkins, the president of Prescott Capital is or was for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended, or otherwise the beneficial owner of any of the shares of common stock of Nature's Sunshine Products, Inc. (the &quot;Common Stock&quot;) purchased by Prescott Group Aggressive Small Cap Master Fund, G.P. (the &quot;Master Fund&quot;) for the accounts of Prescott Group Aggressive Small Cap, L.P.or Prescott Group Aggressive Small Cap II, L.P. (together the &quot;Small Cap Funds&quot;). Pursuant to Rule 16a-1, both Prescott Capital and Mr. Watkins disclaim such beneficial ownership.</footnote>
