consolidation, there shall be substituted for each common share of NADA then
subject to this option the number and kinds of shares of other securities which
each such outstanding common share is so changed or for each such share as
exchanged. Thereafter, the words "common shares of NADA" shall mean such
substituted shares or other securities and the option price of $.087 for each
common share of NADA as specified in paragraph 1 shall apply to and be the
option price for all the shares or other securities substituted for each such
common share of NADA.
