Accordingly, by checking this box instead of one of the price boxes above, the undersigned hereby tenders shares and is willing to accept the purchase price determined by Nature's Sunshine in accordance with the terms of the Offer.

In addition, the undersigned is tendering shares either (check one box):

Conditional Tender
(See Instruction 13 of the Letter of Transmittal)

        A tendering shareholder may condition his or her tender of shares upon Nature's Sunshine purchasing a specified minimum number of the shares tendered, all as described in Section 6 of the Offer to Purchase. Unless at least that minimum number of shares you indicate below is purchased by Nature's Sunshine pursuant to the terms of the Offer, none of the shares tendered will be purchased. It is the tendering shareholder's responsibility to calculate that minimum number of shares that must be purchased if any are purchased, and each shareholder is urged to consult his or her own tax advisor. Unless this box has been checked and a minimum specified, your tender will be deemed unconditional.

o
The minimum number of shares that must be purchased, if any are purchased, is:                 shares.

        If, because of proration, the minimum number of shares designated will not be purchased, Nature's Sunshine may accept conditional tenders by random lot, if necessary.
