siblings, mothers and fathers-in-law, sons and daughters-in-law and brothers
and sisters-in-law, any trusts established solely for the benefit of any of the

of the Company and none of whom is an officer or employee of the Company.

provisions of clauses (b) and (c) of this Section 2, the Rangos Shareholders
and the Company Stockholders agree to use their best efforts to cause (i) the
election (and re-election during the term of this Agreement) of the individuals

election of persons nominated (consistent with the provisions of Section 2(c)
above) by a majority of the Initial Directors to fill any vacancies on the

of the Initial Directors shall be for purposes of this Section 2(d) considered
as though such person were an Initial Director.

Directors consisting of five (5) directors.

                  (b)     The Company and the Company Stockholders agree that
