EFFECTIVENESS

Section 3.01 Effectiveness of Supplemental Indenture. This Supplemental Indenture shall become effective upon execution and delivery of this instrument by each of the parties hereto. Notwithstanding the foregoing sentence, the Amendments set forth in Article 2 hereof shall only become operative on and as of the Early Settlement Date (as defined in the Offering Memorandum), if any, or if there is no such Early Settlement Date, the Final Settlement Date (as defined in the Offering Memorandum) (the earlier of such dates, the “Closing Date”). If the Exchange Offer with respect to any series of Notes is not consummated in accordance with the terms and conditions set forth in the Offering Memorandum, the Amendments set forth in Article 2 hereof shall not become operative with respect to the Notes of such series and shall be null and void for all purposes under the Existing Indenture with respect to the Notes of such series and under the Notes of the applicable series. For the avoidance of doubt, the failure to consummate an Exchange Offer for any series of Notes shall not cause the Amendments set forth in Article 2 hereof to be, or become, inoperative with respect to any other series of Notes for which the Exchange Offer has been consummated.
