     (e) (i) the Share Exchange does not constitute a Default or an Event of Default under the Credit Agreement, and constitutes a Redomestication permitted under the Credit Agreement and (ii) the representations and warranties set forth in Article VI of the Credit Agreement and in the other Loan Documents are true and correct in all material respects as of, and as if such representations and warranties were made on, the Effective Date (unless any such representation and warranty expressly relates to an earlier date, in which case such representation and warranty shall continue to be true and correct as of such earlier date).
