stockholders of Parent will be the same persons who were Company shareholders immediately prior to the Closing (other than holders of exchangeable shares issued by ExchangeCo prior to exchanging them for shares of Parent’s common stock) and Parent will become the direct or indirect owner of all of the assets and liabilities of the Company.
