The Company covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Securities and the Guarantee under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing this Agreement, the Indenture, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities and the Guarantee; (iii) any expenses in connection with the qualification of the Securities and the Guarantee for offering and sale under state securities laws as provided in Section 5(c) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iv) any fees charged by securities rating services for rating the Securities; (v) the filing fees incident to, and up to $20,000 of the fees and disbursements of counsel for the Underwriters in connection with, any required review by the Financial Industry Regulatory Authority, Inc. of the terms of the sale of the Securities and the Guarantee; (vi) the cost of preparing the Securities and the Guarantee; (vii) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture, the Securities and the Guarantee; and (viii) all other costs and expenses incident to the performance of its obligations hereunder that are not otherwise specifically provided for in this Section 7.

9. (a) The Company and the Parent Guarantor, jointly and severally, will indemnify and hold harmless each Underwriter, their respective directors, affiliates and control persons against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither the Company nor the Parent Guarantor shall be liable in

any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company or the Parent Guarantor by any Underwriter through the Representative expressly for use therein.

(b) Each Underwriter severally, but not jointly, will indemnify and hold harmless the Company and the Parent Guarantor, their respective directors, officers who signed the Registration Statement, affiliates and control persons against any losses, claims, damages or liabilities to which the Company or the Parent Guarantor may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company or the Parent Guarantor by such Underwriter through the Representative expressly for use therein; and will reimburse the Company and the Parent Guarantor for any legal or other expenses reasonably incurred by the Company or the Parent Guarantor in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the

written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Parent Guarantor, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Parent Guarantor, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Parent Guarantor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by

reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company and the Parent Guarantor under this Section 9 shall be in addition to any liability that the Company or the Parent Guarantor may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and the Parent Guarantor and to each person, if any, who controls the Company or the Parent Guarantor within the meaning of the Act.

10. (a) If any Underwriter shall default in its obligation to purchase the Securities that it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within 36 hours after such default by any Underwriter you do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company and the Parent Guarantor agree to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Parent Guarantor, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(d) For the avoidance of doubt, to the extent an Underwriter’s obligation to purchase Securities hereunder constitutes a BRRD Liability (as defined below) and such Underwriter does not, at the Time of Delivery, purchase the full amount of the Securities that it has agreed to purchase hereunder due to the exercise by the Relevant Resolution Authority (as defined below) of its powers under the relevant Bail-in Legislation as set forth in Section 24(a) with respect to such BRRD Liability, such Underwriter shall be deemed, for all purposes of this Section 10, to have defaulted on its obligation to purchase such Securities that it has agreed to purchase hereunder but has not purchased, and this Section 10 shall remain in full force and effect with respect to the obligations of the other Underwriters.

11. The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Company, the Parent Guarantor and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, the Company or any officer or director or controlling person of the Company or the Parent Guarantor or any officer or director or controlling person of the Parent Guarantor, and shall survive delivery of and payment for the Securities.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, neither the Company nor the Parent Guarantor shall then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities and the Guarantee are not delivered by or on behalf of the Company and the Parent Guarantor as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but neither the Company nor the Parent Guarantor shall then be under further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly or by the Representative on behalf of you as the representative.

14. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as representative in care of Credit Suisse Securities (USA) LLC, Eleven Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000-0000, Attention: Legal & Compliance Department – Investment Banking Division, and if to the Company or the Parent Guarantor shall be delivered or sent by mail, telex or facsimile transmission to the address of the Parent Guarantor set forth in the most recent Preliminary Prospectus; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company and the Parent Guarantor by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

15. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company, the Parent Guarantor and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and the Parent Guarantor and each person who controls the Company or the Parent Guarantor or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement.

16. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

The

Company and the Parent Guarantor agree that they will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Parent Guarantor, in connection with such transaction or the process leading thereto.

19. The obligation of the Company and the Parent Guarantor in respect of any sum due to any Underwriter shall, notwithstanding any judgment in a currency other than U.S. dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company and the Parent Guarantor agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company or the Parent Guarantor, as the case may be, an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter hereunder.

20. The Company and the Parent Guarantor each hereby submits to the non-exclusive jurisdiction of the federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company and the Parent Guarantor each irrevocably appoints Noble Drilling Services Inc. as its authorized agent upon which process may be served in any such suit or proceeding, and agrees that service of process upon such agent, and written notice of said service to the Company or the Parent Guarantor, as applicable, by the person serving the same to Noble Drilling Services Inc. at 00000 Xxxxx Xxxxx Xxxxxxx, Xxxxx 000, Xxxxx Xxxx, XX 00000, shall be deemed in every respect effective service of process upon the Company or the Parent Guarantor, as applicable, in any such suit or proceeding.

21. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company or the Parent Guarantor, on the one hand, and the Underwriters, or any of them, on the other, with respect to the subject matter hereof.

22. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.

23. The Company, the Parent Guarantor and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

24. (a) Notwithstanding any other term of this Agreement or any other agreement, arrangement, or understanding between or among any of the parties to this Agreement, each of the parties to this Agreement acknowledges, accepts, and agrees to be bound by:

(1) the effect of the exercise of Bail-in Powers by the Relevant Resolution Authority in relation to any BRRD Liability of a BRRD Party (the “Relevant BRRD Party”) to the Company or the Guarantor, as applicable, under this Agreement, that (without limitation) may include and result in any of the following, or some combination thereof:

(iv) the amendment or alteration of any interest, if applicable, thereon or the dates on which any payments are due, including by suspending payment for a temporary period; and

25. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

26. Notwithstanding anything herein to the contrary, the Company and the Parent Guarantor are authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company or the Parent Guarantor relating to that treatment and structure without the Underwriters imposing any limitation of any kind.

Accordingly, purchasers who wish to trade the Notes on the date of pricing of the Notes or the next five succeeding business days will be required by virtue of the fact that the Notes initially will settle in T+9, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.

Changes to the Preliminary Prospectus Supplement

Offering Size:

Tender Offers:

The previously announced Maximum Purchase Amount of the Tender Offers has been upsized up to $750 million and the Cap with respect to the 4.90% Senior Notes due 2020 has been increased to $300 million. The Tender Offers are conditioned on the completion of the offering of the Notes for gross proceeds of at least $750 million. All other terms of the Tender Offers are unchanged.

Use of Proceeds:

The Issuer intends to use the net proceeds from the offering, together with cash on hand, to pay the purchase price and accrued interest (together with fees and expenses) in the Tender Offers. Any remaining proceeds will be used for general corporate purposes, which may include further retirement of debt, including the further purchase of debt in open market or privately negotiated transactions.

Original Issue Discount:

The Notes are being issued with original issue discount (“OID”) for U.S. federal income tax purposes in an amount equal to the difference between their stated principal amount and their “issue price” (i.e., the first price at which a substantial amount of Notes are sold for cash to persons other than bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). A U.S. holder generally will be required to include the OID in gross income (as ordinary income) in advance of the receipt of cash attributable to that income and regardless of such holder’s regular method of tax accounting. Such OID will be included in gross income using a “constant yield” method, in which case the U.S. holder will have to include in income increasingly greater amounts of OID in successive accrual periods. A U.S. holder’s adjusted tax basis in a Note will be increased by any OID previously included in income

Schedule IV -3

with respect to that Note. All holders are urged to consult their own tax advisors regarding the application of the OID rules to their particular circumstances.

Credit Ratings

On December 13, 2016, S&P Global Ratings downgraded Noble UK’s debt rating by two notches to BB- with a negative outlook. As a result, the interest rates on our Senior Notes due 2018, Senior Notes due 2025 and Senior Notes due 2045 will increase to 5.75%, 7.70% and 8.70%, respectively, beginning with the first day of the next interest period.

Other information (including financial information) presented in the Preliminary Prospectus Supplement is deemed to have changed to the extent affected by the changes described herein.

The Issuer and the Guarantor have filed a registration statement (including a prospectus and related Preliminary Prospectus Supplement for the offering) with the U.S. Securities and Exchange Commission (the “SEC”) for the offering to which this communication relates. Before you invest, you should read the Preliminary Prospectus Supplement, the accompanying prospectus in that registration statement and the other documents the Issuer has filed with the SEC for more complete information about the Issuer and this offering. You may get these documents for free by visiting XXXXX on the SEC’s website at xxx.xxx.xxx. Alternatively, the Issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by contacting Credit Suisse Securities (USA) LLC at xxxxxxxxx.xxxxxxxxxx@xxxxxx-xxxxxx.xxx.

This communication should be read in conjunction with the Preliminary Prospectus Supplement and the accompanying prospectus. The information in this communication supersedes the information in the Preliminary Prospectus Supplement and the accompanying prospectus to the extent it is inconsistent with the information in such Preliminary Prospectus Supplement or the accompanying prospectus.

Schedule IV -4

ANNEX I

FORM OF OPINION OF XXXXX XXXXX L.L.P.

FOR THE COMPANY AND THE PARENT GUARANTOR

1. When the Securities have been authenticated in the manner set forth in the Indenture and delivered against due payment therefor pursuant to the terms of this Agreement, the Securities and the Guarantee will constitute valid and legally binding obligations of the Company and the Parent Guarantor, respectively, enforceable against the Company and the Parent Guarantor, respectively, in accordance with their terms, except as enforceability is subject to (i) any applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or conveyance or other laws relating to or affecting creditors’ rights generally, (ii) general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law) and (iii) any implied covenants of good faith and fair dealing. The descriptions in the final term sheet prepared and filed pursuant to Section 5(a) of this Agreement and the information set forth under the captions “Description of Debt Securities” and “Description of the Notes” in the Pricing Prospectus and the Prospectus, insofar as such statements constitute a summary of the terms of the Securities, the Guarantee and the Indenture, are accurate summaries of the Securities, the Guarantee and the Indenture, in all material respects.

2. Assuming the due authorization, execution and delivery thereof by the Company, the Parent Guarantor and the Trustee, the Indenture constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as enforceability is subject to (i) any applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or conveyance or other laws relating to or affecting creditors’ rights generally, (ii) general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law) and (iii) any implied covenants of good faith and fair dealing. The Indenture has been qualified under the Trust Indenture Act.

3. The execution, delivery and performance by the Company and the Parent Guarantor of this Agreement and the Indenture do not violate or result in any breach of (i) any agreement or instrument filed as an exhibit to or incorporated by reference into the Registration Statement or (ii) any Applicable Laws, except, in the case of clause (i), for any such violations or breaches that, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. “Applicable Laws” is defined as the federal laws of the State of New York and the laws of the United States of America that, in such counsel’s experience, are normally applicable to transactions of the type provided for in this Agreement and the Indenture.

4. No consent, approval, authorization, order, registration or qualification of or with any Applicable Governmental Authority is required for the issue and sale by the Company of the Securities, the making of the Guarantee by the Parent Guarantor or the performance by the Company or the Parent Guarantor of their obligations under this Agreement or the Indenture, except such as have been obtained under the Act and the Trust Indenture Act, and such consents, approvals, authorizations, orders, registrations or qualifications as may be required under the state securities or blue sky laws in connection with the purchase and distribution of the Securities by the Underwriters. “Applicable Governmental Authority” is defined as any governmental body, agency or court of the United States of America or the State of New York.

Annex I-1

5. Neither the Company nor the Parent Guarantor is, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectus neither will be, an “investment company,” as such term is defined in the Investment Company Act.

6. The statements contained in the Pricing Disclosure Package and the Prospectus under the caption “Material U.S. Federal Income Tax Considerations,” insofar as they purport to constitute summaries of matters of United States federal tax law and regulations or legal conclusions with respect thereto, are accurate in all material respects.

Such counsel will also provide the following:

Such counsel has reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and has participated in conferences with officers and other representatives of the Company and the Parent Guarantor, with representatives of the Parent Guarantor’s independent registered public accounting firm and with your representatives and your counsel, at which the contents of the Registration Statement, the Pricing Disclosure Package, the Prospectus and related matters were discussed. The purpose of such counsel’s professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the Pricing Disclosure Package or the Prospectus, and such counsel has not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus involve matters of a non-legal nature. Accordingly, such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent stated in the last sentence of paragraph 1 above). Subject to the foregoing and on the basis of the information such counsel gained in the course of performing the services referred to above, such counsel advises you that:

(a) the Registration Statement, as of the latest effective time, the Pricing Prospectus, as of the Applicable Time, and the Prospectus, as of its date and the Time of Delivery, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder; and

(b) nothing came to such counsel’s attention that caused it to believe that:

(i) the Registration Statement, as of the latest effective time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(ii) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

Annex I-2

(iii) the Prospectus, as of its date or as of the Time of Delivery, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case such counsel has not been asked to, and does not, express any belief with respect to (a) the financial statements and schedules or other financial or accounting information contained or included or incorporated by reference therein or omitted therefrom, (b) representations and warranties and other statements of fact contained in the exhibits to the Registration Statement or to documents incorporated by reference in the Registration Statement or (c) that part of the Registration Statement that constitutes the Form T-1.

The execution and delivery of the Transaction Documents by the Company and the Parent Guarantor, as applicable, and the issue and offer of the Notes by the Company and the performance of its obligations thereunder, and the issue of the Guarantee by the Parent Guarantor and the performance of its obligations thereunder, do not conflict with or result in a breach of any of the terms or provisions of the Company Memorandum and Articles and the PG Memorandum and Articles respectively or any law, public rule or regulation applicable to the Company or the Parent Guarantor in the Cayman Islands currently in force.

3.4

The execution, delivery and performance of the Transaction Documents have been authorised by and on behalf of the Company and the Parent Guarantor, as applicable, the Transaction Documents have been duly executed and delivered on behalf of the Company and the Parent Guarantor, as applicable, and constitute the legal, valid and binding obligations of the Company and the Parent Guarantor, as applicable, enforceable in accordance with their terms.

3.5

The Notes have been authorised by the Company and when authenticated in the manner set forth in the Indenture and delivered against due payment therefor will be duly executed and delivered and will constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms.

3.6

The Guarantee has been authorised by the Parent Guarantor and when the Notes have been authenticated in the manner set forth in the Indenture and delivered against due payment therefore will constitute the legal, valid and binding obligations of the Parent Guarantor enforceable in accordance with its terms.

3.7	No authorisations, consents, approvals, licences, validations or exemptions are required by law from any governmental authorities or agencies or other official bodies in the Cayman Islands in connection with:

(a)

the execution or delivery of the Transaction Documents by the Company and the Parent Guarantor, as applicable;

(b)

subject to the payment of stamp duty, the enforcement of the Transaction Documents against the Company or the Parent Guarantor, as applicable;

(c)

the offering, execution, authentication, allotment, issue or delivery of the Notes;

(d)

the execution, issue or delivery of the Guarantee;

(e)

the performance by the Company and the Parent Guarantor, as applicable, of its obligations under the Notes, the Guarantee and the Transaction Documents; or

Annex II-4

(f)

the payment of the principal and interest and any other amounts under the Notes and the Guarantee.

3.8	No taxes, fees or charges (other than stamp duty) are payable (either by direct assessment or withholding) to the government or other taxing authority in the Cayman Islands under the laws of the Cayman Islands in respect of:

(a)

the execution or delivery of the Transaction Documents; the Notes or the Guarantee;

(b)

the enforcement of the Transaction Documents; the Notes or the Guarantee;

(c)

payments made under, or pursuant to, the Transaction Documents; or

(d)

the issue, transfer or redemption of the Notes.

The Cayman Islands currently have no form of income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax.

3.9	The courts of the Cayman Islands will observe and give effect to the choice of the laws of the State of New York as the governing law of the Transaction Documents and the Notes.

3.10

Based solely on our search of the Register of Writs and Other Originating Process and the Register of Appeals (together, the “Court Registers”) maintained by the Clerk of the Court of the Grand Court of the Cayman Islands and by the Registrar of the Court of Appeal of the Cayman Islands respectively from the date of incorporation of the Company and the Parent Guarantor, as applicable to [ ] 2016 (the “Litigation Search”), the Court Registers disclosed no writ, originating summons, originating motion, petition, counterclaim nor third party notice (“Originating Process”) nor any amended Originating Process pending before the Grand Court of the Cayman Islands nor any appeal pending before the Court of Appeal, in which the Company or the Parent Guarantor is a defendant or respondent.

3.11

Although there is no statutory enforcement in the Cayman Islands of judgments obtained in the State of New York, a judgment obtained in such jurisdiction will be recognised and enforced in the courts of the Cayman Islands at common law, without any re-examination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided such judgment:

(a)

is given by a foreign court of competent jurisdiction;

(b)

imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given;

(c)

is final;

(d)

is not in respect of taxes, a fine or a penalty; and

Annex II-5

(e)

was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands.

3.12	It is not necessary to ensure the legality, validity, enforceability or admissibility in evidence of the Transaction Documents; the Notes or the Guarantee that any document be filed, recorded or enrolled with any governmental authority or agency or any official body in the Cayman Islands.

3.13

Based solely on our review of the Register of Members of the Parent Guarantor, the issued shares in the capital of the Parent Guarantor (the “Parent Guarantor Issued Shares”) are 261,245,693 ordinary shares of US$0.10 each and Noble Corporation Holdings Ltd. is the registered holder of all the Parent Guarantor Issued Shares. The Parent Guarantor Issued Shares have been duly authorised and validly issued and, assuming that payment for such Parent Guarantor Issued Shares has been received in full in accordance with the terms of issue, are fully paid.

3.14

Based solely on our review of the Register of Members of the Company, the issued shares in the capital of the Company (the “Company Issued Shares”) are 10,006 shares of US$1.00 each and Noble Holding International S.a.r.l. (formerly known as Noble Holding International SCA) is the registered holder of all the Company Issued Shares. The Company Issued Shares have been duly authorised and validly issued and, assuming that payment for such Company Issued Shares has been received in full in accordance with the terms of issue, are fully paid.

3.15	All statements made in the Prospectus with regard to statutes, regulations, rules, treaties and other laws of the Cayman Islands are accurate.

3.16	The statements set forth in the Prospectus under the caption “Cayman Islands Tax Considerations”, to the extent they constitute statements of Cayman Islands law, are accurate in all material respects and to the extent they are statements of legal conclusions, constitute our opinion.

4	Qualifications

The opinions expressed above are subject to the following qualifications:

4.1

The term “enforceable” as used above means that the obligations assumed by the Company and the Parent Guarantor, as applicable, under the Transaction Documents; the Notes and the Guarantee are of a type which the courts of the Cayman Islands will enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular:

(a)

enforcement may be limited by bankruptcy, insolvency, liquidation, reorganisation, readjustment of debts or moratorium or other laws of general application relating to or affecting the rights of creditors;

(b)

enforcement may be limited by general principles of equity. For example, equitable remedies such as specific performance may not be available, inter alia, where damages are considered to be an adequate remedy;

Annex II-6

(c)

some claims may become barred under the statutes of limitation or may be or become subject to defences of set off, counterclaim, estoppel and similar defences;

(d)

where obligations are to be performed in a jurisdiction outside the Cayman Islands, they may not be enforceable in the Cayman Islands to the extent that performance would be illegal under the laws of that jurisdiction;

(e)

the courts of the Cayman Islands have jurisdiction to give judgment in the currency of the relevant obligation and statutory rates of interest payable upon judgments will vary according to the currency of the judgment. If the Company or the Parent Guarantor becomes insolvent and is made subject to a liquidation proceeding, the courts of the Cayman Islands will require all debts to be proved in a common currency, which is likely to be the “functional currency” of the Company or the Parent Guarantor determined in accordance with applicable accounting principles. Currency indemnity provisions have not been tested, so far as we are aware, in the courts of the Cayman Islands;

(f)

arrangements that constitute penalties will not be enforceable;

(g)

enforcement may be prevented by reason of fraud, coercion, duress, undue influence, misrepresentation, public policy or mistake or limited by the doctrine of frustration of contracts;

(h)

provisions imposing confidentiality obligations may be overridden by compulsion of applicable law or the requirements of legal and/or regulatory process;

(i)

the courts of the Cayman Islands may decline to exercise jurisdiction in relation to substantive proceedings brought under or in relation to the Transaction Documents or the Notes in matters where they determine that such proceedings may be tried in a more appropriate forum;

(j)

we reserve our opinion as to the enforceability of the relevant provisions of the Transaction Documents to the extent that they purport to grant exclusive jurisdiction as there may be circumstances in which the courts of the Cayman Islands would accept jurisdiction notwithstanding such provisions; and

(k)

a company cannot, by agreement or in its articles of association, restrict the exercise of a statutory power, and there exists doubt as to enforceability of any provision in the Transaction Documents whereby the Company or the Parent Guarantor covenants not to exercise powers specifically given to its shareholders by the Companies Law (2016 Revision) of the Cayman Islands, including, without limitation, the power to increase its authorised share capital, amend its memorandum and articles of association, or present a petition to a Cayman Islands court for an order to wind up the Company or the Parent Guarantor.

4.2	Applicable court fees will be payable in respect of the enforcement of the Transaction Documents and the Notes.

Annex II-7

4.3	Cayman Islands stamp duty may be payable if the original Transaction Documents or the original Notes (if not registered Notes) are brought to or executed in the Cayman Islands.

4.4	To maintain a Cayman Islands company in good standing under the laws of the Cayman Islands, annual filing fees must be paid and returns made to the Registrar of Companies within the time frame prescribed by law.

4.5

The obligations of the Company and the Parent Guarantor may be subject to restrictions pursuant to United Nations sanctions as implemented under the laws of the Cayman Islands and/or restrictive measures adopted by the European Union Council for Common Foreign and Security Policy extended to the Cayman Islands by the Order of Her Majesty in Council.

4.6

A certificate, determination, calculation or designation of any party to the Transaction Documents or the Notes as to any matter provided therein might be held by a Cayman Islands court not to be conclusive final and binding if, for example, it could be shown to have an unreasonable or arbitrary basis, or in the event of manifest error.

4.7

The Litigation Search of the Court Registers would not reveal, amongst other things, an Originating Process filed with the Grand Court which, pursuant to the Grand Court Rules or best practice of the Clerk of the Courts’ office, should have been entered in the Court Registers but was not in fact entered in the Court Registers (properly or at all) ), or any Originating Process which has been placed under seal or anonymised (whether by order of the Court or pursuant to the practice of the Clerk of the Courts’ office, in either case save for winding up petitions, which pursuant to O.24 r.6(1) of the Companies (Winding Up) Rules (as amended) may not be placed under seal).

4.8

In principle a Cayman Islands court will award costs and disbursements in litigation in accordance with the relevant contractual provisions but there remains some uncertainty as to the way in which the rules of the Grand Court will be applied in practice. Whilst it is clear that costs incurred prior to judgment can be recovered in accordance with the contract, it is likely that post-judgment costs (to the extent recoverable at all) will be subject to taxation in accordance with Grand Court Rules Order 62.

4.9

Preferred creditors under Cayman Islands law will rank ahead of unsecured creditors of the Company and the Parent Guarantor. Furthermore, all costs, charges and expenses properly incurred in the voluntary winding up of a company, including the remuneration of the liquidators, are payable out of the assets of the company in priority to all other unsecured claims.

4.10

We reserve our opinion as to the extent to which the courts of the Cayman Islands would, in the event of any relevant illegality or invalidity, sever the relevant provisions of the Transaction Documents and enforce the remainder of the Transaction Documents or the transaction of which such provisions form a part, notwithstanding any express provisions in the Transaction Documents in this regard.

4.11	We note that it is contemplated that certain of the Transaction Documents will be dated “as of” a certain date. Whilst parties to an agreement may agree as a matter of contract,

Annex II-8

inter se, that the rights and obligations therein contained should, in so far as the same may be possible, take effect from a date prior to the date of execution and delivery, if as a matter of fact that agreement was executed and delivered after the date “as of” which it is expressed to be executed and delivered, the agreement only comes into effect on the actual date of execution and delivery and, with respect to third parties, the agreement in so far as the rights of third parties may be available thereunder, take effect only from the actual date of execution and delivery.

4.12

Under the Companies Law (2016 Revision) of the Cayman Islands, the register of members of a Cayman Islands company is by statute regarded as prima facie evidence of any matters which the Companies Law (2016 Revision) directs or authorises to be inserted therein. A third party interest in the shares in question would not appear. An entry in the register of members may yield to a court order for rectification (for example, in the event of fraud or manifest error).

4.13	We make no comment with regard to the references to foreign statutes in the Transaction Documents or the Notes.

We express no view as to the commercial terms of the Transaction Documents or the Notes or whether such terms represent the intentions of the parties and make no comment with respect to any representations which may be made by the Company or the Parent Guarantor.

The opinions in this opinion letter are strictly limited to the matters contained in the opinions section above and do not extend to any other matters. We have not been asked to review and we therefore have not reviewed any of the ancillary documents relating to the Transaction Documents and express no opinion or observation upon the terms of any such document.

This opinion may be relied upon by the addressees only, except as set forth below. We are aware that Xxxxx Xxxxx L.L.P. will rely as to matters of Cayman Islands law on this opinion in rendering its opinion to the Trustee and we authorise them to so rely. This opinion may not be relied upon by any other person except with our prior written consent.

Yours faithfully

Xxxxxx and Calder
