When available, Praxair will mail the proxy statement/prospectus to its stockholders in connection with the vote to approve the merger of Praxair and a wholly-owned subsidiary of New Holdco, and New Holdco will distribute the offering prospectus to Linde shareholders in the United States in connection with New Holdco’s offer to acquire all of the outstanding shares of Linde.
