that, in the event the restrictions set forth in this Agreement are specifically
enforced or otherwise become operative, Dr. Fassihi will be able to engage in a
business or pursuit for purposes of earning a livelihood which does not
necessitate breach of or other failure to comply with this Agreement.

         14.      Termination. The Term may be terminated at any time by either
party for any reason or no reason by giving the other party thirty (30) days
advance written notice of such termination.

         15.      Assignment. Nutraceutix may assign this Agreement to a
division, subsidiary or other affiliated entity of Nutraceutix. This Agreement
and Dr. Fassihi's duties pursuant to this Agreement may not be assigned or
otherwise delegated by Dr. Fassihi. Subject to the foregoing, this Agreement
shall be binding upon and inure to the benefit of Nutraceutix and its
successors, assigns and legal representatives and on Dr. Fassihi and Dr.
Fassihi's heirs, administrators, and personal representatives.

         16.      Miscellaneous. This Agreement shall be governed by and
construed in accordance with the laws of the State of Washington. No amendment,
modification or waiver of this Agreement shall be valid unless evidenced by a
written instrument signed by the party to be bound thereby. The provisions of
paragraphs 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 15, and all other provisions
of this Agreement which may reasonably be interpreted or construed as surviving
the expiration or termination of the Term, shall survive the expiration or
termination of the Term. This Agreement constitutes the entire agreement between
the parties with respect to the subject matter hereof and supersedes any and all
prior and contemporaneous agreements, negotiations, correspondence, undertakings
and communications of the parties, oral or written, with respect to that subject
matter.
