Each of the Preliminary Memorandum and the Final Memorandum sets forth certain information concerning the Company, the Guarantors and the Securities. The Company hereby confirms that it has authorized the use of the Disclosure Package (as defined below), the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers. Unless stated to the contrary, any references herein to the terms “amend”, “amendment” or “supplement” with respect to the Disclosure Package, the Preliminary Memorandum and the Final Memorandum shall be deemed to refer to and include any information filed under the Exchange Act (as defined below) subsequent to the Execution Time (as defined below) that is incorporated by reference therein.

(c) Not to amend or supplement the Disclosure Package or the Final Memorandum other than by filing documents under the Exchange Act that are incorporated by reference therein, without the prior written consent of the Representative; provided, however, that prior to the completion of the distribution of the Securities by the Initial Purchasers, neither the Parent Guarantor nor the Company will file any document under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum unless, prior to such proposed filing, the Parent Guarantor or the Company has furnished the Representative with a copy of such document for its review and the Representative has not reasonably objected to the filing of such document. The Parent Guarantor or the Company will promptly advise the Representative when any document filed under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum shall have been filed with the Commission.

(d) If at any time prior to the completion of the sale of the Securities by the Initial Purchasers (as determined by the Representative), any event occurs as a result of which the Disclosure Package or the Final Memorandum, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing, not misleading, or if it should be necessary to amend or supplement the Disclosure Package or the Final Memorandum to comply with applicable law, the Parent Guarantor and the Company will promptly (i) notify the Representative of any such

event; (ii) subject to the requirements of Section 5(c), prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) supply any supplemented or amended Disclosure Package or Final Memorandum to the several Initial Purchasers and counsel for the Initial Purchasers without charge in such quantities as they may reasonably request.

(n) During the period beginning from the date hereof and continuing to and including the later of the Closing Date and such earlier time as the Representative may notify the Company, not to offer, sell, contract to sell, or otherwise dispose of any debt securities of the Company or any Guarantor that mature more than one year after such Closing Date and that are substantially similar to the Securities or the Guarantees; provided that, for clarification purposes, nothing in this Section 5(n) shall limit the ability of the Parent Guarantor or any of its subsidiaries to incur indebtedness under or enter into any credit facility.

(o) Neither the Company nor any Guarantor will take, directly or indirectly, any action designed to, or that has constituted or that might reasonably be expected to, cause or result, under the Exchange Act, in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(p) The Company will, for a period of twelve months following the Execution Time, furnish to the Representative (i) all reports or other communications (financial or other) generally made available to its shareholders, and deliver such reports and communications to the Representative as soon as they are available, unless such documents are furnished to or filed with the Commission or any securities exchange on which any class of securities of the Company or the Parent Guarantor is listed and generally made available to the public and (ii) such additional information concerning the business and financial condition of the Parent Guarantor and its subsidiaries as the Representative may from time to time reasonably request (such statements to be on a consolidated basis to the extent the accounts of the Parent Guarantor and its subsidiaries are consolidated in reports furnished to its shareholders).

(q) To comply with all applicable securities and other laws, rules and regulations, and use their respective best efforts to cause the their respective directors and officers, in their capacities as such, to comply with such laws, rules and regulations.

(t) All payments to be made to each Initial Purchaser pursuant to this Agreement shall be made without any withholding or deduction for or on account of any present or future taxes, duties, or governmental charges unless the Company or a Guarantor is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company or the Guarantor, as the case may be, shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made. The parties to this Agreement shall use commercially reasonable efforts to minimize the imposition of any such taxes, duties or charges.

(i) The Securities shall be eligible for clearance and settlement through The Depository Trust Company;

(j) On or after the Execution Time (i) no downgrading shall have occurred in the rating accorded the debt securities of the Company or the Parent Guarantor by ▇▇▇▇▇’▇ Investors Service, Inc.

7. Reimbursement of Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company or any Guarantor to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally through the Representative on demand for all out of pocket expenses (including reasonable fees and disbursements of counsel) that shall have been reasonably incurred by them in connection with the proposed purchase and sale of the Securities. Other than such reimbursement obligations, the Company and the Guarantors shall have no further liability to the Representative or any Initial Purchaser except as provided in Section 5(r) and Section 8 hereof.

8. Indemnification and Contribution. (a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information, or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or supplement thereto, 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, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that neither the Company nor any Guarantor will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or

omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company or the Parent Guarantor by or on behalf of any Initial Purchaser through the Representative specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 8(b) hereof. This indemnity agreement will be in addition to any liability that the Company and/or the Guarantors may otherwise have.

(b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company and each of the Guarantors and their affiliates, each of their respective directors, each of their respective officers, and each person who controls the Company or any such Guarantor or affiliate within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser (including reimbursement for any legal or other expenses), but only with reference to written information relating to such Initial Purchaser furnished to the Company or the Parent Guarantor by or on behalf of such Initial Purchaser through the Representative specifically for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise have. The Company and the Guarantors acknowledge that, under the heading “Plan of Distribution” in the Preliminary Memorandum and the Final Memorandum, (A) the fourth and fifth sentences of the sixth paragraph and (B) and the seventh and eighth paragraphs constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party

and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent: (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding 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) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Guarantors and the Initial Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Company and/or the Guarantors and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Initial Purchasers on the other from the offering of the Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason, then each indemnifying party severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company or any Guarantor on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), in no event shall any Initial Purchaser be required to contribute any amount in excess of the amount by which the total purchase discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who

controls an Initial Purchaser within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company or any Guarantor within the meaning of either the Securities Act or the Exchange Act and each officer and director of the Company or such Guarantor shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser, the Company or any Guarantor. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company, any Guarantor or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. For the avoidance of doubt, to the extent an Initial Purchaser’s obligation to purchase Securities hereunder constitutes a BRRD Liability (as defined below) and such Initial Purchaser does not, at the Closing Date, 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 21(a) with respect to such BRRD Liability, such Initial Purchaser shall be deemed, for all purposes of this Section 9, to have defaulted on its obligation to purchase such Securities that it has agreed to purchase hereunder but has not purchased, and this Section 9 shall remain in full force and effect with respect to the obligations of the other Initial Purchasers.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited; (ii) trading in Noble-UK’s securities on The New York Stock Exchange shall have been suspended or materially limited; (iii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; (iv) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services; or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final ▇▇▇▇▇▇▇▇▇▇.

▇▇

▇▇. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company and the Guarantors or their respective officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers, the Company or any Guarantor or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(k) hereof, no other person will have any right or obligation hereunder.

14. Jurisdiction. The Company and each Guarantor agrees that any suit, action or proceeding against the Company or such Guarantor brought by any Initial Purchaser, the directors, officers, employees and agents of any Initial Purchaser, or by any person who controls any Initial Purchaser, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State or U.S. federal court in The City of New York and County of New York, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. The Company and the Guarantors each irrevocably appoints Noble Drilling Services Inc. at ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇ as its authorized agent (the “Authorized Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein that may be instituted in any State or U.S. federal court in The City of New York and County of New York, by any Initial Purchaser, the directors, officers, employees, Affiliates and agents of any Initial Purchaser, or by any person who controls any Initial Purchaser, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. The Company and each Guarantor hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company and each Guarantor agree to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid.

18. No Fiduciary Duty. The Company and each of the Guarantors hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the Initial Purchasers and any Affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company or any Guarantor and (c) the Company’s and the Guarantors’ engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity.

If the amount in the relevant currency that may be so purchased for any reason falls short of the amount originally due, the Company or a Guarantor, as applicable, will pay such additional amounts, in the relevant currency, as may be necessary to compensate for the shortfall. Any obligation of the Company or any Guarantor not discharged by such payment will, to the fullest extent permitted by applicable law, be due as a separate and independent obligation and, until discharged as provided herein, will continue in full force and effect.

20. Waiver of Immunity. To the extent that the Company or any Guarantor has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its property, the Company and the Guarantors hereby irrevocably waive and agree not to plead or claim such immunity in respect of their respective obligations under this Agreement.

When the Securities have been executed and authenticated in the manner set forth in the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of this Agreement, the Securities and the Guarantees will constitute valid and legally binding obligations of the Company and the Guarantors, respectively, enforceable against the Company and the Guarantors, respectively, in accordance with their terms, except that such enforceability may be limited by (a) applicable bankruptcy, insolvency, fraudulent conveyance or transfer, reorganization, moratorium or similar laws of general applicability relating to or affecting creditors’ rights and remedies and to general principles of equity (whether considered in a proceeding in equity or at law) and comity and (b) public policy, applicable law relating to fiduciary duties and indemnification and contribution and any implied covenants of good faith and fair dealing (the “Enforceability Exceptions”).

3. The statements set forth in the Disclosure Package and the Final Memorandum under the caption “Description of the Notes,” insofar as such statements constitute a summary of the terms of the Securities, the Guarantees and the Indenture, are accurate in all material respects.

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 and the Guarantors, enforceable against the Company and the Guarantors in accordance with its terms, except that such enforceability may be limited by the Enforceability Exceptions.

Annex I-2

discussed. The purpose of such counsel’s professional engagement was not to establish or confirm factual matters set forth in the Disclosure Package or the Final Memorandum, 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 Disclosure Package and the Final Memorandum 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 Disclosure Package and the Final Memorandum (except to the extent stated in paragraphs 3 and 9 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 nothing came to its attention that caused it to believe that:

(a) the Disclosure Package, as of the Effective 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

(b) the Final Memorandum, as of its date or as of the date of such opinion, 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 do 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 or (b) representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.
