We refer to the Agreement and Plan of Merger (the "Merger Agreement"), by and
among you ("Vital Living"), VLEN Acquisition Corp., Inc. ("Merger Sub") and

Date"). Whereas it is one of the conditions to close of the merger contemplated

investors are offered differing terms, the investment will be made on terms no
less favorable than the most favorable terms provided to such investors.
