 SECTION 2. MISCELLANEOUS 

Section 2.1 Trust Indenture Act Controls. If any provision of this Eighth Supplemental Indenture limits, qualifies or conflicts
with any provision of the Trust Indenture Act that is required under the Trust Indenture Act to be part of and govern the Supplemented Indenture, such provision of the Trust Indenture Act shall control. If any provision hereof modifies or excludes
any provision of the Trust Indenture Act that may be so modified or excluded, such provision of the Trust Indenture Act shall be deemed to apply to this Eighth Supplemental Indenture, as so modified or excluded, as the case may be. 

Section 2.2 Effectiveness. The provisions of this Eighth Supplemental Indenture shall be effective only upon execution and
delivery of this instrument by the parties hereto. Notwithstanding the foregoing sentence, the provisions of this Eighth Supplemental Indenture shall become operative only upon the purchase by NHIL of at least a majority in principal amount of the
outstanding Notes pursuant to the Tender Offers, with the result that the amendments to the Supplemented Indenture effected by this Eighth Supplemental Indenture shall be deemed to be revoked retroactively to the date hereof if such purchase shall
not occur. Holding shall give prompt written notice of (a) whether payment of the purchase of the Notes by Holding pursuant to the Tender Offers has been made and (b)(i) whether such purchase is of at least a majority in principal amount of the
outstanding Notes pursuant to the Tender Offers and the provisions of this Eighth Supplemental Indenture shall become operative with respect to the Notes or (ii) whether the provisions of this Eighth Supplemental Indenture shall not become
operative and the amendments to the Supplemented Indenture effected by this Eighth Supplemental Indenture shall be deemed revoked retroactively to the date hereof with respect to the Notes. 

Section 2.3 Supplemental Indenture Incorporated into Supplemented Indenture. The terms and conditions of this Eighth Supplemental
Indenture shall be deemed to be part of the Supplemented Indenture for all purposes relating to the Notes. The Supplemented Indenture is hereby incorporated by reference herein and, as further supplemented by this Eighth Supplemental Indenture, is
in all respects adopted, ratified and confirmed. Noble-Cayman hereby confirms that its guarantee pursuant to the Supplemented Indenture shall apply to the Notes and the Supplemented Indenture in accordance with the terms of the Notes and the
Supplemented Indenture as amended by this Eighth Supplemental Indenture. 
 Section 2.4 Notes Deemed Conformed. As of the date
hereof, the provisions of the Notes and the guarantee of Noble-Cayman pursuant to the Supplemented Indenture shall be deemed to be conformed, without the necessity for any reissuance or exchange of such Notes or any other action on the part of the
Holders of the Notes, Holding, NDS6, Drilling Holding, Noble-Cayman or the Trustee, so as to reflect this Eighth Supplemental Indenture. 

Section 2.5 Successors. All agreements of Holding, NDS6, Drilling Holding, Noble-Cayman and the Trustee in this Eighth
Supplemental Indenture and in the Supplemented Indenture shall bind their respective successors and assigns, whether or not so expressed. 

Section 2.6 Benefits of Eighth Supplemental Indenture. Nothing in this Eighth Supplemental Indenture, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Eighth Supplemental Indenture or the Supplemented Indenture.

 Section 2.7 Separability. In case any provision in this Eighth Supplemental
Indenture, or in the Supplemented Indenture, shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby, it being intended that all of the
provisions hereof shall be enforceable to the full extent permitted by law. 
 Section 2.8 Headings. The section headings of
this Eighth Supplemental Indenture have been inserted for convenience of reference only, are not to be considered a part of this Eighth Supplemental Indenture and shall in no way modify or restrict any of the terms or provisions hereof. 

Section 2.9 Definitions. Each capitalized term used but not defined in this Eighth Supplemental Indenture shall have the meaning
assigned to such term in the Supplemented Indenture. 
 Section 2.10 Governing Law; Jury Trial Waiver. THIS EIGHTH SUPPLEMENTAL
INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY. EACH OF HOLDING, NDS6, DRILLING HOLDING, NOBLE-CAYMAN AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS EIGHTH SUPPLEMENTAL INDENTURE OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 Section 2.11 Counterparts. This
Eighth Supplemental Indenture may be executed in two or more counterparts, each of which shall constitute an original, but all of which when taken together shall constitute the same instrument. The exchange of copies of this Eighth Supplemental
Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Eighth Supplemental Indenture as to the parties hereto and may be used in lieu of the original Eighth Supplemental Indenture
for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 

Section 2.12 Trustee Not Responsible for Recitals. The recitals herein contained are made by Holding, NDS6, Drilling Holding and
Noble-Cayman, and not by the Trustee, and the Trustee assumes no responsibility for the correctness thereof. The Trustee makes no representations as to, and shall not be responsible for, the validity or sufficiency of this Eighth Supplemental
Indenture, the Tender Offers, the Offer to Purchase and Consent Solicitation Statement dated January 17, 2018, the accompanying Letter of Transmittal and Consent and the related consents, and the Trustee assumes no responsibility for the
correctness of same. All rights, protections, privileges, indemnities and benefits granted or afforded to the Trustee under the Supplemented Indenture shall be deemed incorporated herein by this reference and shall be deemed applicable to all
actions taken, suffered or omitted by the Trustee under this Eighth Supplemental Indenture.
