“S&P” means S&P Global Ratings, a division of S&P Global, Inc., and its successors.

“Significant Shareholder” means each of (i) the Parent Guarantor or any of its Subsidiaries and (ii) any other “person” (as that term is used in Section 13(d)(3) of the Exchange Act) if 50% or more of the Voting Stock of such person is “beneficially owned” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, by the Parent Guarantor or one of its Subsidiaries or any combination thereof.
