                           vote of Pala or such director violates his or her
                           fiduciary duties to the Company;

                  (ii)     any vacancies created by the resignation, removal or

unissued shares of Common Stock available for conversion of indebtedness under
the Debenture Agreement outstanding at any given time and to maintain the
provisions in the Company's Articles of Incorporation set forth in Schedule K to
the Debenture Agreement, and to ensure that at all times during the term of this
Agreement the Bylaws of the Company permit telephonic meetings of the Board in
the manner permitted by applicable law.

and delivery such transferee shall be deemed to be a Party hereto as if such
transferee was an original signatory hereto.
