WHEREAS, pursuant to Section 9.02(a) of the Indenture, the Issuer and the Guarantors desire to execute this Supplemental Indenture in order to give effect to the Proposed Amendments, as provided hereinafter (subject to the conditions set forth in Section 3 below);

WHEREAS, all conditions precedent set forth in the Consent Solicitation Statement and the Indenture to the execution and delivery of this Supplemental Indenture by the Issuer, the Guarantors and the Trustee have been satisfied, and all things necessary have been done to make this Supplemental Indenture, when executed and delivered by the Issuer and the Guarantors, the legal, valid and binding agreement of the Issuer and the Guarantors; and

WHEREAS, the Issuer and the Guarantors have requested that the Trustee execute and deliver this Supplemental Indenture;

NOW, THEREFORE in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties to this Supplemental Indenture hereby agree as follows:

SECTION 1. Definitions. For all purposes of this Supplemental Indenture, except as otherwise herein expressly provided or unless the context otherwise requires: (i) the terms and expressions used herein shall have the same meanings as corresponding terms and expressions used in the Indenture; and (ii) the words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

SECTION 2. Amendments. The Indenture is hereby amended as follows:

(a)    The definition of “Change of Control” set forth in Section 1.01 of the Indenture (Definitions) is hereby amended and restated in its entirety as follows:

- 1 -

“Change of Control” means the occurrence of any of the following:

(1)     the sale, lease, transfer or other conveyance, in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any Person; or

(2)     the Company becomes aware of (by way of a report or any other filing pursuant to Section 13(d) of the Exchange Act, proxy, vote, written notice or otherwise) the acquisition by any Person or group (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act, or any successor provision), including any group acting for the purpose of acquiring, holding or disposing of securities (within the meaning of Rule 13d-5(b)(1) under the Exchange Act), in a single transaction or in a related series of transactions, by way of merger, consolidation or other business combination or purchase of beneficial ownership, directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the Company or any entity of which it is a Subsidiary; provided that so long as the Company is a Subsidiary of Parent, no Person or group shall be deemed to be or become a beneficial owner, directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the Company or any entity of which it is a Subsidiary, as applicable, unless such Person or group shall be or become, directly or indirectly, a beneficial owner of more than 50% of the total voting power of the Voting Stock of Parent.

(b)    All references in the Indenture and any Global Note representing the Notes, as amended by Section 2 hereof, to any of the provisions modified as provided herein, or to terms defined in such provisions, shall also be deemed modified in accordance with the terms of this Supplemental Indenture.

SECTION 3. Effectiveness of Proposed Amendments. This Supplemental Indenture shall be effective as a binding agreement upon execution hereof by the Issuer, the Guarantors and the Trustee; provided, however, that the Proposed Amendments set forth in Section 2 hereof shall not become effective and operative until the Issuer’s delivery of an Officers’ Certificate to the Trustee confirming that the Issuer has paid the Consent Fee (as defined in the Consent Solicitation Statement) to the consenting Holders of Notes in accordance with the Consent Solicitation Statement (it being understood the Proposed Amendments shall become immediately and fully effective and operative upon delivery of such notice of payment). If (a) the Consent Fee has not been paid on or prior to the earlier of (i) the date of the consummation of the Re-Domiciliation Transaction (as defined in the Consent Solicitation Statement) and (ii) March 29, 2018, or (b) at any time following the execution of this Supplemental Indenture, the Issuer notifies the Trustee in writing that the Issuer no longer wishes to give effect to the Proposed Amendments and does not intend to pay the Consent Fee at any time, then this Supplemental Indenture shall, from and after, in the case of clause (a) above, the earlier of the dates, and in the case of clause (b) above, the date of the Issuer’s delivery of such notice to the Trustee, become and be null and void ab initio. The Issuer shall be under no obligation to pay the Consent Fee in the event the Issuer no longer wishes to give effect to the Proposed Amendments.

SECTION 4. Ratification of Indenture; Supplemental Indenture Part of Indenture. Except as expressly waived, amended or otherwise modified hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder of Notes heretofore or hereafter authenticated and delivered shall be bound hereby.

SECTION 5. Governing Law.

SECTION 6. Trustee Makes No Representation. The Trustee makes no representation as to the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which are made by the Issuer.

SECTION 7. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. Delivery of

- 2 -
