such aggregate consideration (whether in the form of cash, securities or
otherwise) had been distributed by the Corporation in complete liquidation
pursuant to the rights and preferences set forth in the Corporation's
Certificate of Incorporation as in effect immediately prior to such Approved
Sale; (ii) if any stockholders of the Corporation are given an option as to the
form and amount of consideration to be received, each stockholder of such class
of the Corporation will be given the same option; and (iii) each stockholder of
then currently exercisable rights to acquire shares of a class of the
