The obligations in this Section 6.5 shall not require the Company, the Parent Issuer, the Subsidiary Issuer, any Debtor or any Backstop Party to (1) take any action or share any information which is restricted or prohibited by obligations of confidentiality binding on the Company, the Parent Issuer, the Subsidiary Issuer, any Debtor or any Backstop Party, applicable Law or the rules of any applicable securities exchange (provided that such Party must only withhold the portion of such information or materials that are actually subject to such confidentiality obligations, applicable Law or rules of any applicable securities exchange and, unless otherwise restricted from doing so by any of the aforementioned, use commercially reasonable efforts to provide such withheld information or materials on an outside counsel only basis or subject to other agreed upon confidentiality safeguards), (2) disclose any document or share any information over which the Company, the Parent Issuer, the Subsidiary Issuer, any Debtor or any Backstop Party asserts any legal professional privilege nor waive or forego the benefit of any applicable legal professional privilege or (3) disclose any non-public business data or similar information of a Filing Party, except such data or information as may be necessary to establish jurisdictional filing or notification requirements, or as may be required in order to obtain any Antitrust and Foreign Investment Approvals, which shall be shared on a counsel-only basis.

Without the prior written consent of the Requisite Backstop Parties, neither the Company nor any of the other Debtors shall commit or agree to (x) dispose of, license or hold separate any of its assets or (y) limit its freedom of action with respect to any of its businesses or commit or agree to any of the foregoing, in each case, in order to secure any necessary consent or approvals for the transactions contemplated hereby under the Antitrust and Foreign Investment Laws. Notwithstanding anything to the contrary herein, neither the Backstop Parties, nor any of their Affiliates, nor the Company or any of the other Debtors, shall

52

be required as a result of this Agreement, to initiate any legal action against, or defend any litigation brought by, the United States Department of Justice, the United States Federal Trade Commission, or any other Governmental Entity in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any suit or proceeding which would otherwise have the effect of preventing or materially delaying the transactions contemplated hereby, or which may require any undertaking or condition set forth in the preceding sentence.

All requests for information and access made in accordance with this Section 6.6 shall be directed to an executive officer of the Company or such person as may be designated by the Company’s executive officers; provided, however, that the Company may condition the provision of any information under this Section 6.6 on the entry by the applicable Backstop Party into a customary non-disclosure agreement with the Company, in form and substance reasonably satisfactory to the Company and such Backstop Party.

Section 6.7 Financial Information.

(a) At all times prior to the Closing Date, the Company shall deliver to counsel to each Backstop Party and to each Backstop Party that so requests, subject to appropriate assurance of confidential treatment, all statements and reports the Company is required to deliver pursuant to any credit agreement, indenture or similar agreement or instrument to which the Company is or any of the other Debtors is a party (as in effect on the date hereof) (the “Financial Reports”). Neither any waiver by the lenders or other counterparties under such agreement or instrument of their right to receive the Financial Reports nor any amendment or termination of such agreement or instrument shall affect the Company’s obligation to deliver the Financial Reports to the Backstop Parties in accordance with the terms of this Agreement.

53

(b) The Financial Reports (i) shall be complete and correct in all material respects and (ii) shall be deemed to have been delivered in accordance with Section 6.7(a) on the date on which the Company posts such information on the Company’s website on the internet at www.noblecorp.com or makes such information available via the EDGAR system of the SEC on the internet (to the extent such information has been posted, filed, furnished or is otherwise available).

Section 6.8 Alternative Transactions.

(a) During the Pre-Closing Period, (i) the Company and the other Debtors shall, and shall instruct and direct their respective Representatives to, immediately cease and terminate any ongoing solicitation with respect to any Alternative Transaction, and (ii) the Company and the other Debtors shall not, and the Company and the other Debtors shall instruct and direct their respective Representatives not to, solicit, support, file or prosecute any Alternative Transaction or object to or take any other action that would reasonably be expected to prevent, interfere with, delay, or impede approval of this Agreement, solicitation, approval of the Disclosure Statement, or the confirmation and consummation of the Plan and the Restructuring. Notwithstanding the foregoing sentence, if following the date of this Agreement (x) if the Company or any of the other Debtors receives a proposal or offer for an Alternative Transaction not solicited in violation of this Section 6.8 (an “Alternative Transaction Proposal”) from any Person and (y) the Board has determined in good faith, after consultation with its outside legal counsel and its financial advisor, that failure to consider and engage in discussions and negotiations in connection with respect to such Alternative Transaction Proposal would be inconsistent with their fiduciary duties, then the Company, the other Debtors, and their Representatives shall not be prohibited from considering and engaging in negotiations with respect to the Alternative Transaction Proposal consistent with the Company’s and the Board’s exercise of their fiduciary duties; provided that if the Company receives an Alternative Transaction Proposal, then the Company shall (A) within one (1) calendar day of receiving such Alternative Transaction Proposal, notify in writing the Backstop Parties of the receipt of such Alternative Transaction Proposal and deliver a copy of such Alternative Transaction Proposal to the Backstop Parties and their respective Representatives, including Kramer Levin and Milbank; (B) keep the Backstop Parties reasonably informed of the status and terms of any such Alternative Transaction Proposal (including any amendments thereto), the status of any such discussions or negotiations, including any change in the Company’s intentions as previously notified; and (C) use commercially reasonable efforts to respond promptly to reasonable information requests and questions from the Backstop Parties regarding such Alternative Transaction. Notwithstanding anything else contained herein, none of the Company or any of the other Debtors shall enter into any confidentiality agreement with a party in connection with an Alternative Transaction unless the Company notifies the Backstop Parties in writing prior to such entry into the non-disclosure agreement, as well as upon execution thereof.

(b) Subject to the Company’s compliance with this Section 6.8, during the Pre-Closing Period, the Board may approve an Alternative Transaction Proposal not solicited in violation of this Section 6.8 that the Board has determined in good faith, after consultation with its outside legal counsel and its financial advisor, that failure to approve the Alternative Transaction Proposal would reasonably be expected to be inconsistent with its fiduciary duties, provided that the Board notifies the Backstop Parties in writing at least two (2) Business Days in advance that it intends to take such action or that the Company intends to terminate this Agreement pursuant to Section 9.1(d)(ii). Upon the receipt of such notice, the Requisite Backstop Parties shall have the right to immediately terminate this Agreement pursuant to Section 9.1(c)(ii)(A).

54

(c) Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement shall require a Debtor or the board of directors, board of managers, or similar governing body of a Debtor, after consulting with outside counsel, to take any action or to refrain from taking any action with respect to the Restructuring, including terminating this Agreement pursuant to Section 9.1(d)(ii), to the extent taking or failing to take such action would be inconsistent with applicable Law or its fiduciary obligations under applicable Law, and any such action or inaction pursuant to this Section 6.8 shall not be deemed to constitute a breach of this Agreement; provided that this Section 6.8 shall not impede any Party’s right to terminate this Agreement pursuant to Article IX, including, for the avoidance of doubt, the Backstop Parties’ right to terminate in accordance with Section 9.1(c); provided, further, that the Debtors shall provide three (3) Business Days’ notice, to the extent reasonably practicable, to the Ad Hoc Guaranteed Group Backstop Parties and the Ad Hoc Legacy Group Backstop Parties (with email to Kramer Levin and Milbank being sufficient) prior to taking any action or refraining from taking any action in reliance on this Section 6.8 (and in any event no later than the date on which the Debtors take or refrain from taking any such action). Upon the receipt of such notice, the Requisite Backstop Parties shall have the right to terminate this Agreement pursuant to Section 9.1(c)(ii)(C).

Section 6.9 Commercially Reasonable Efforts.

(a) Without in any way limiting any other respective obligation of the Debtors or any Backstop Party in this Agreement, the Debtors shall use, and each Backstop Party shall use, commercially reasonable efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable in order to consummate and make effective the transactions contemplated by this Agreement, the Plan and the other Transaction Agreements, including using commercially reasonable efforts in:

(i) timely preparing and filing all documentation reasonably necessary to effect all necessary notices, reports and other filings of such Party and to obtain as promptly as practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any third party or Governmental Entity;

(ii) in the case of the Debtors, except as set forth in Section 6.5(e), defending any Legal Proceedings challenging this Agreement, the Plan or any other Transaction Agreement or the consummation of the transactions contemplated hereby and thereby, including seeking to have any stay or temporary restraining order entered by any Governmental Entity vacated or reversed; and

(iii) working together in good faith to finalize the Registration Rights Agreement and the Reorganized Noble Corporate Documents for timely inclusion in the Plan Supplement and filing with the Bankruptcy Court.

55

(b) Subject to applicable Laws relating to the exchange of information, the Backstop Parties and the Company shall have the right to review in advance, and to the extent practicable each will consult with the other on all of the material information relating to Backstop Parties or the Company, as the case may be, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any third party and/or any Governmental Entity in connection with the transactions contemplated by this Agreement or the Plan; provided, however, that the Backstop Parties are not required to provide for review in advance declarations or other evidence submitted in connection with any filing with the Bankruptcy Court. In exercising the foregoing rights, each of the Company and the Backstop Parties shall act reasonably and as promptly as practicable.

(c) Nothing contained in this Section 6.8 shall limit the ability of any Debtor or Backstop Party (i) to consult with any other Debtor, any other Backstop Party, or any other party in interest in the Chapter 11 Cases, (ii) to appear and be heard, or (iii) to file objections, in each case, concerning any matter arising in the Chapter 11 Cases.

Section 6.10 Exit Revolver. The Debtors agree to use good faith commercially reasonable efforts to enter into the Exit Revolver.

Section 6.12 Registration Rights Agreement. The Plan will provide that from and after the Closing Date, the Backstop Parties shall be entitled to certain registration rights with respect to the Second Lien Notes and New Shares issued in connection with the Rights Offering, this Agreement and the Plan, in each case that are issued other than pursuant to Section 1145 of the Bankruptcy Code, or which are deemed to be securities held by affiliates of the Issuers, as determined under applicable securities Laws (the “Registrable Securities”), pursuant to a customary registration rights agreement in form and substance consistent with the terms set forth in this Agreement and the Restructuring Support Agreement and otherwise on terms and conditions reasonably satisfactory to the Company and the Requisite Backstop Parties (the “Registration Rights Agreement”). A form of the Registration Rights Agreement shall be filed with the Bankruptcy Court as part of the Plan Supplement. The Registration Rights Agreement shall provide for, among other things (subject to customary exceptions and conditions), the filing of a resale registration statement covering all Registrable Securities and, in the case of New Shares, customary demand and piggyback registration rights. The Company, the Parent Issuer or the Subsidiary Issuer (as applicable) shall cause such registration statement to be filed as promptly as practicable and in any event within thirty (30) or sixty (60) days (as set forth in the Restructuring Term Sheet) following the Effective Date, and to use its commercially reasonable best efforts to cause the registration statement to be declared effective by the staff of the SEC as promptly as practicable thereafter. During the Pre-Closing Period, the Parties will cooperate in good faith to negotiate the terms and conditions of penny warrants to be issued upon request of any Backstop Party that would otherwise receive New Shares representing beneficial ownership of 10% or more of the aggregate issued and outstanding New Shares such that any such Backstop Party would have beneficial ownership of less than 10% of the New Shares (any such warrants, “Penny Warrants”), which such Penny Warrants shall have no antidilution protection except in the case of stock splits and stock dividends and similar events or circumstances and shall otherwise be in form and substance mutually agreeable to such Backstop Party and the Company or the Parent Issuer (as applicable), taking into account, among other things, any possible tax or other adverse consequences thereof to the Company or the Parent Issuer (as applicable), in which case the New Shares issuable upon exercise of such Penny Warrants shall be included in the resale shelf registration statement.

56

Section 6.13 Blue Sky. The Issuers shall, on or before the Closing Date, take such action as the Issuers shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Unregistered Securities issued hereunder for, sale to the Backstop Parties at the Closing Date pursuant to this Agreement under applicable securities and “Blue Sky” Laws of the states of the United States (or to obtain an exemption from such qualification) or similar Laws of the UK or EU and shall provide evidence (to the extent reasonably available) of any such action so taken to the Backstop Parties on or prior to the Closing Date. The Issuers shall timely make all filings and reports, if any, relating to the offer and sale of the Unregistered Securities issued hereunder required under applicable securities and “Blue Sky” Laws of the states of the United States following the Closing Date. The Issuers shall pay all fees and expenses in connection with satisfying their respective obligations under this Section 6.13.

Section 6.14 No Integration; No General Solicitation. Neither the Company nor any of its affiliates (as defined in Rule 501(b) of Regulation D promulgated under the Securities Act) will, directly or through any agent, sell, offer for sale, solicit offers to buy or otherwise negotiate in respect of, any security (as defined in the Securities Act), that is or will be integrated with the sale of the Unregistered Securities, the Rights Offering and this Agreement in a manner that would require registration under the Securities Act of the Unregistered Securities to be issued by the Company on the Effective Date. None of the Company or any of its affiliates or any other Person acting on its or their behalf will solicit offers for, or offer or sell, any Unregistered Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D promulgated under the Securities Act.

Section 6.15 Fungibility and Liquidity. The Second Lien Notes and New Shares issued in connection with the Rights Offering and this Agreement (including the Holdback Securities and the Backstop Premium) are to be DTC-eligible, other than any Second Lien Notes or New Shares required to bear a “restricted” legend under applicable securities laws (which shall be in DTC under a restricted CUSIP, if feasible, or otherwise in book entry form). The Issuers shall use commercially reasonable efforts to promptly make, when applicable from time to time after the Closing, all Unlegended Securities eligible for deposit with DTC. Notwithstanding anything herein to the contrary, the Parties will continue to evaluate potential alternative securities law and transfer restriction treatment for the Second Lien Notes and the New Shares issued pursuant to this Agreement, with a view toward maximizing the liquidity and fungibility of the issuances of the Second Lien Notes and the issuances of the New Shares. In all events, the Second Lien Notes and the New Shares shall be made fungible as promptly as possible (including the same CUSIP), including as contemplated by the Registration Rights Agreement. Such alternative treatment shall be reasonably satisfactory to the Issuers and the Requisite Backstop Parties.

57

Section 6.16 Use of Proceeds. The Debtors will apply the proceeds from the exercise of the Rights, the Exit Revolver and the issuance of the Holdback Securities and the Backstop Securities, in each case, pursuant to the Plan.

Section 6.17 Legends.

(a) To the extent any Unregistered Shares are issued, each certificate evidencing Unregistered Shares and each certificate issued in exchange for or upon the transfer, sale or assignment of any such securities, shall be stamped or otherwise imprinted with a legend (the “Share Legend”) in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED ON [DATE OF ISSUANCE], HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY OTHER APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN AVAILABLE EXEMPTION FROM REGISTRATION THEREUNDER AND APPLICABLE STATE SECURITIES LAWS.”

To the extent any uncertificated Unregistered Shares are issued, such Unregistered Shares shall be subject to a restrictive notation substantially similar to the Share Legend in the stock ledger or other appropriate records maintained by the Parent Issuer or agent and the term “Share Legend” shall include such restrictive notation. The Share Legend (or restrictive notation, as applicable) set forth above shall be removed from the certificates evidencing any such securities (or the records, in the case of uncertificated shares), upon request at any time after the restrictions described in such legend cease to be applicable. The Parent Issuer may reasonably request such opinions, certificates or other evidence that such restrictions no longer apply as a condition of removing the Share Legend (or restrictive notation, as applicable).

(b) To the extent any Unregistered Notes are issued, each certificate evidencing Unregistered Notes and each certificate issued in exchange for or upon the transfer, sale or assignment of any such securities, shall be stamped or otherwise imprinted with a legend (the “Note Legend”) in substantially the following form:

“THIS SENIOR SECURED SECOND LIEN NOTE HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY OTHER APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN AVAILABLE EXEMPTION FROM REGISTRATION THEREUNDER AND APPLICABLE STATE SECURITIES LAWS.”

58

To the extent any uncertificated Unregistered Notes are issued, such Unregistered Notes shall be subject to a restrictive notation substantially similar to the Note Legend in the ledger or other appropriate records maintained by the Subsidiary Issuer or agent and the term “Note Legend” shall include such restrictive notation. The Note Legend (or restrictive notation, as applicable) set forth above shall be removed from the certificates evidencing any such securities (or the records, in the case of uncertificated notes), upon request at any time after the restrictions described in such legend cease to be applicable. The Subsidiary Issuer may reasonably request such opinions, certificates or other evidence that such restrictions no longer apply as a condition of removing the Note Legend (or restrictive notation, as applicable).

Section 6.18 Issuer Joinder. If the Parent Issuer or the Subsidiary Issuer is to be a Person other than a Debtor on the date hereof, then promptly after the creation of such Person, the Company shall cause such Person to join this Agreement pursuant to a joinder agreement in form and substance attached hereto as Exhibit B.

ARTICLE VIII

INDEMNIFICATION AND CONTRIBUTION

Section 8.1 Indemnification Obligations. Following the entry of the BCA Approval Order, the Company and the other Debtors (the “Indemnifying Parties” and each an “Indemnifying Party”) shall, jointly and severally, indemnify and hold harmless each Backstop Party that is not a Defaulting Backstop Party, its Affiliates, shareholders, members, partners and other equity holders, general partners, managers and its and their respective Representatives, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and costs and expenses (other than Taxes) in respect of any third party claim or any claim asserted by any Debtor (collectively, “Losses”) that any such Indemnified Person may incur or to which any such Indemnified Person may become subject arising out of or in connection with this Agreement, the Plan and the transactions contemplated hereby and thereby, including the Backstop Commitment, the Rights Offering, the payment of the Backstop Premiums or the use of the proceeds of the Rights Offering, or any breach by the Debtors of this Agreement, or any claim or Legal Proceeding relating to any of the foregoing, regardless of whether any Indemnified Person is a party thereto, and reimburse each Indemnified Person upon demand for reasonable and documented (subject to redaction to preserve attorney client and work product privileges) legal or other third-party out-of-pocket expenses (excluding any VAT such Indemnified Person (or a member of the Indemnified Person’s group for VAT purposes) may recover (whether by credit, repayment or otherwise) comprised in such expenses) incurred in connection with investigating, preparing to defend or defending, or providing evidence in or preparing to serve or serving as a witness with respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing (including in connection with the enforcement of the

63

indemnification obligations set forth herein), irrespective of whether or not the transactions contemplated by this Agreement or the Plan are consummated or whether or not this Agreement is terminated; provided that the foregoing indemnity will not, as to any Indemnified Person, apply to Losses (a) as to a Defaulting Backstop Party and its Related Parties, caused by a Backstop Party Default by such Backstop Party, or (b) to the extent they are found by a final, non-appealable judgment of a court of competent jurisdiction to arise from the bad faith, willful misconduct or gross negligence of such Indemnified Person.

Section 8.2 Indemnification Procedure. Promptly after receipt by an Indemnified Person of notice of the commencement of any claim or Legal Proceeding (an “Indemnified Claim”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnifying Party in respect thereof, notify the Company (or its successor) in writing of the commencement thereof; provided that (i) the omission to so notify the Company will not relieve the Indemnifying Party from any liability that it may have hereunder except to the extent it has been materially prejudiced by such omission and (ii) the omission to so notify the Company will not relieve the Indemnifying Party from any liability that it may have to such Indemnified Person otherwise than on account of this Article VIII. In case any such Indemnified Claims are brought against any Indemnified Person and it notifies the Company of the commencement thereof, the Indemnifying Party will be entitled to participate therein, and, to the extent that it may elect by written notice delivered to such Indemnified Person, to assume the defense thereof, with counsel reasonably acceptable to such Indemnified Person; provided that if the parties (including any impleaded parties) to any such Indemnified Claims include both such Indemnified Person and the Indemnifying Party and based on advice of such Indemnified Person’s counsel there are legal defenses available to such Indemnified Person that are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Indemnified Claims. Upon receipt of notice from the Indemnifying Party to such Indemnified Person of its election to so assume the defense of such Indemnified Claims with counsel reasonably acceptable to the Indemnified Person, the Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such Indemnified Person in connection with the defense thereof (other than reasonable costs of investigation) unless (A) such Indemnified Person shall have employed separate counsel (in addition to any local counsel) in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in which local counsel is required) and that all such expenses shall be reimbursed as they occur), (B) the Indemnifying Party shall not have employed counsel reasonably acceptable to such Indemnified Person to represent such Indemnified Person within a reasonable time after notice of commencement of the Indemnified Claims, (C) the Indemnifying Party shall have failed or is failing to defend such claim, and is provided written notice of such failure by the Indemnified Person and such failure is not reasonably cured within ten (10) Business Days of receipt of such notice, or (D) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Person. Notwithstanding anything herein to the contrary, the Company and the other Debtors shall have sole control over any Tax controversy or Tax audit and shall be permitted to settle any liability for Taxes of the Company and the other Debtors.

64

Section 8.3 Settlement of Indemnified Claims. The Indemnifying Party shall not be liable for any settlement of any Indemnified Claims effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed). If any settlement of any Indemnified Claims is consummated with the written consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such Indemnified Claims, the Indemnifying Party agrees to indemnify and hold harmless each Indemnified Person from and against any and all Losses by reason of such settlement or judgment to the extent such Losses are otherwise subject to indemnification by the Indemnifying Party hereunder in accordance with, and subject to the limitations of, the provisions of this Article VIII. The Indemnifying Party shall not, without the prior written consent of an Indemnified Person (which consent shall be granted or withheld in the Indemnified Person’s sole discretion), effect any settlement of any pending or threatened Indemnified Claims in respect of which indemnity or contribution has been sought hereunder by such Indemnified Person unless (A) such settlement includes an unconditional release of such Indemnified Person in form and substance reasonably satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such Indemnified Claims and (B) such settlement does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

Section 8.4 Contribution. If for any reason the foregoing indemnification is unavailable to any Indemnified Person or insufficient to hold it harmless from Losses that are subject to indemnification pursuant to Section 8.1 (other than any unavailability or insufficiency pursuant to the terms thereof), then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a result of such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, but also the relative fault of the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Persons, on the other hand, shall be deemed to be in the same proportion as (a) the total value received or proposed to be received by the Company pursuant to the issuance of the Backstop Securities, the Rights Offering Securities in the Rights Offering contemplated by this Agreement and the Plan bears to (b) the Backstop Premiums paid or proposed to be paid to the Backstop Parties.

Section 8.5 Treatment of Indemnification Payments. The obligations of the Debtors under this Article VIII shall constitute allowed administrative expenses of the Debtors’ estates under sections 503(b) and 507 of the Bankruptcy Code and are payable without further Order of the Bankruptcy Court, and the Debtors may comply with the requirements of this Article VIII without further Order of the Bankruptcy Court.

Section 8.6 Survival. All representations, warranties, covenants and agreements made in this Agreement shall not survive the Closing Date except for covenants and agreements that by their terms are to be satisfied after the Closing Date, which covenants and agreements shall survive until satisfied in accordance with their terms.

65

notice of termination no later than five (5) Business Days after the failure to satisfy such Milestone; provided, further, that the determination of whether the Company failed to satisfy any Milestone on a date specified in the Restructuring Support Agreement (as modified, waived or extended in accordance with the Restructuring Support Agreement) shall be without regard to the Debtors’ use of commercially reasonable efforts to satisfy such Milestone;

(ii) subject to any applicable notice or cure period, (A) the Debtors file any pleading or document with the Bankruptcy Court, enter into any transaction or Contract (an “Alternative Transaction Agreement”) or support or make a written proposal or counterproposal to any party, in each case (x) with respect to a reorganization, restructuring, merger, consolidation, share exchange, rights offering, equity investment, business combination, recapitalization, sale or other Alternative Transaction or (y) that is inconsistent with the Rights Offering and/or the Plan, in either case other than in any immaterial respect, (B) the Bankruptcy Court approves or authorizes an Alternative Transaction at the request of any party in interest or (C) the Debtors provide notice of their intention to take or refrain from taking, or actually take or refrain from taking, any action in reliance on Section 6.8(c);

For the avoidance of doubt, the three (3) Business Day period provided for herein shall be coterminous with the Termination Notice Period; or

67

(vi) the Bankruptcy Court grants relief that (A) is inconsistent with this Agreement in any material respect or (B) would, or would reasonably be expected to, frustrate the purposes of this Agreement, including by preventing the consummation of the Restructuring, without the approval of the Requisite Backstop Parties.

(ii) the Company enters into any Alternative Transaction Agreement; provided that the Company may only terminate this Agreement pursuant to this Section 9.1(d)(ii) if the Company has not breached any of its obligations under Section 6.8; or

Absent such waiver, this Agreement shall be terminated on the fourth (4th) day following delivery of the termination notice pursuant to Article IX. Upon termination pursuant to this Article IX, this Agreement shall forthwith become void and there shall be no further obligations or liabilities on the part of the Debtors or the Backstop Parties; provided that (i) the obligations of the Debtors to pay the Expense Reimbursement pursuant to Article III (with respect to such portions of the Expense Reimbursement incurred prior to the date of such termination) and to satisfy their indemnification obligations pursuant to Article VIII shall survive the termination of this Agreement indefinitely and shall remain in full force and effect, in each case, until such obligations have been satisfied, (ii) the

68

provisions set forth in this Section 9.2 and Article X shall survive the termination of this Agreement in accordance with their terms (with respect to Section 9.2(b), so long as the BCA Approval Order has been entered by the Bankruptcy Court prior to such termination), and (iii) subject to Section 10.10, nothing in this Section 9.2 shall relieve any Party from liability for any willful or intentional breach of this Agreement. For purposes of this Agreement, “willful or intentional breach” means a breach of this Agreement that is a consequence of an act undertaken by the breaching Party with the knowledge (actual or constructive) that the taking of such act would, or would reasonably be expected to, cause a breach of this Agreement.

The provisions with respect to the payment of the Termination Payment are an integral part of the transactions contemplated by this Agreement and without these provisions the Backstop Parties would not have entered into this Agreement. Notwithstanding anything to the contrary in this Agreement, the Parties hereby acknowledge and agree that (i) in no event shall the Debtors be obligated to pay the Termination Payment on more than one occasion and (ii) in the event that the Termination Payment is paid in accordance with this Section 9.2(b), the Termination Payment shall be the Backstop Parties’ sole and exclusive remedy in respect of any breach of this Agreement by the Debtors. The Termination Payment shall constitute an allowed administrative expense of the Debtors’ estates under Sections 503(b) and 507 of the Bankruptcy Code.

RIGHTS OFFERING PROCEDURES¹

To Eligible Holders and Nominees of Eligible Holders:

The Plan (as defined below) provides for the Debtors to conduct a Rights Offering pursuant to which certain Holders of Claims may acquire Second Lien Notes and corresponding note guarantees and the Participation Equity (as defined below) (collectively, the “Rights Offering Securities”).

These Rights Offering Procedures relate to the Rights Offering for the Rights Offering Securities, which will be issued in reliance on the exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”) provided by Section 1145 of the Bankruptcy Code to the maximum extent possible and, to the extent such exemption is unavailable, will be issued solely to qualified holders in reliance on the exemption provided by Section 4(a)(2) under the Securities Act and Regulation D promulgated thereunder, or another available exemption, as applicable.

The subscription and issuance of the Unsubscribed Securities (as defined below) and, if applicable, the Holdback Securities (as defined below) by and to the applicable Backstop Parties pursuant to the Backstop Commitment Agreement will be made in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act or another available exemption from registration under the Securities Act, as applicable. The issuance of the Backstop Premiums to the applicable Backstop Parties pursuant to the Backstop Commitment Agreement will be made in reliance on the exemption from registration under the Securities Act provided by Section 1145 of the Bankruptcy Code. The issuance of Holdback Securities to the Joining Legacy Parties (as defined below) will be made in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act or another available exemption from registration under the Securities Act, as applicable. For the avoidance of doubt, the Unsubscribed Securities, Holdback Securities, and Backstop Premiums will be subscribed for pursuant to separate arrangements/agreements and not pursuant to these Rights Offering Procedures.

You should read these Rights Offering Procedures in their entirety; key provisions are highlighted below:

Eligible Holders should note the following times relating to the Rights Offering:

On October 8, 2020, the Debtors filed the Plan and the Disclosure Statement with Respect to the Second Amended Joint Plan of Reorganization of Noble Corporation plc and Its Debtor Affiliates [Docket No. 530] (as may be amended from time to time in accordance with its terms, the “Disclosure Statement”).

The Rights Offering

Pursuant to the Plan, each Eligible Holder (other than a Backstop Party) will have the right, but not the obligation, to participate in the Rights Offering in respect of the Rights Offering Securities; provided, however, that Eligible Holders that are Backstop Parties must exercise their Subscription Rights pursuant to the Backstop Commitment Agreement. The parties entitled to participate in the Rights Offering (the “Eligible Holders”) are Holders of the following Claims (collectively, the “Eligible Claims”):

provided that no Record Date shall apply to the Notes Claims.

For the avoidance of doubt, only holders of Allowed General Unsecured Claims against Debtor Group B or Debtor Group C are entitled to participate in the Rights Offering, and only with respect to such Allowed Claims. Subject to Section 9 below, the eligibility of any exercise of Subscription Rights will be determined in good faith by the Debtors in consultation with the Requisite Backstop Parties, and, if necessary, subject to a final and binding determination by the Bankruptcy Court.

To the extent any issuance of Rights Offering Securities to a Holder of Eligible Claims would not qualify for the exemption from registration under the Securities Act provided by Section 1145 of the Bankruptcy Code, such a holder shall only be an Eligible Holder if it certifies that it is any of the following:

9

Allocation of Rights Offering Securities

Subject to the terms and conditions set forth in the Plan, the Backstop Commitment Agreement, these Rights Offering Procedures, and the Subscription Forms:

(a) the Eligible Holders are entitled to subscribe for, on the Effective Date, at an aggregate subscription price of $200,000,000 for the Rights Offering Securities, $200,000,000 (less the aggregate nominal value of the Participation Equity (as defined below)) in aggregate principal amount of Second Lien Notes, of which (i) $116,000,000 (less the aggregate nominal value of 58% of the Participation Equity) in aggregate principal amount of Second Lien Notes (equal to 58% of the Second Lien Notes offered in connection with the Rights Offering) shall be offered to Eligible Holders of General Unsecured Claims against Debtor Group B (including Priority Guaranteed Notes Claims) (the “Guaranteed Notes Allocation”) and (ii) $84,000,000 (less the aggregate nominal value of 42% of the Participation Equity) in aggregate principal amount of Second Lien Notes (equal to 42% of the Second Lien Notes offered in connection with the Rights Offering) shall be offered to Eligible Holders of the General Unsecured Claims against Debtor Group C (including Legacy Notes Claims) (the “Legacy Notes Allocation”); and

(b) each participant in the Rights Offering in respect of the Guaranteed Notes Allocation shall subscribe for its pro rata share (based on the amount of such participant’s outstanding Guaranteed Notes) of 8,700,000 New Shares (equal to 17.4% of the New Shares issued and outstanding immediately after the Effective Date (subject to dilution by the Warrants and the MIP (each as defined in the Backstop Commitment Agreement)) and each participant in the Rights Offering in respect of the Legacy Notes Allocation shall subscribe for its pro rata share (based on the amount of such participant’s outstanding Legacy Notes) of 6,300,000 New Shares (equal to 12.6% of the New Shares issued and outstanding immediately after the Effective Date (subject to dilution by the Warrants and the MIP)) (collectively, the “Participation Equity”);

provided, that the Rights Offering Securities available for subscription shall be reduced to account for the Holdback Securities (which shall only be available for subscription by the Ad Hoc Guaranteed Group, the Ad Hoc Legacy Group, and certain Eligible Holders of the Legacy Notes (the “Joining Legacy Parties”) that participated in a joinder process to commit to fund a portion of the Rights Offering (the “Backstop Joinder Process”)).⁶

For any Eligible Holder of Notes Claims: As part of the exercise process, following exercise of Subscription Rights, any related Notes held through DTC will be frozen from trading, as described below. With respect to Eligible Holders who hold Notes Claims, all Subscription Forms or other instructions required by their respective Nominee must be returned to

10

the applicable Nominee in sufficient time to allow such Nominee to process and deliver the underlying Notes through The Depository Trust Company (“DTC”) Automated Tender Offer Program (“ATOP”), which is how the related Subscription Rights will be exercised by those Eligible Holders of Notes Claims. By giving the instruction to its Nominee to submit the underlying Notes through ATOP, such Eligible Holder is (i) authorizing its Nominee to exercise the Subscription Rights associated with the amount of Notes as to which the instruction pertains and corresponding to the elections evidenced on such holder’s Subscription Form (and/or other instruction required by such Nominee); and (ii) certifying that it understands that, following the Rights Offering Expiration Time, the underlying Notes will be frozen from trading until the Effective Date, at which point (a) the underlying Notes will be cancelled pursuant to the Plan; and (b) the Eligible Holder will receive its pro rata share of the Rights Offering Securities distributed to its Class pursuant to the Plan and any other treatment afforded to such Class pursuant to the Plan. The amount of time necessary for a Nominee to process and deliver the applicable Notes through ATOP may vary. If applicable, Eligible Holders are urged to consult with their Nominees to determine the necessary deadline to return their Subscription Forms or other instructions required by their Nominee to their Nominee. Failure to deliver the applicable Notes through ATOP on a timely basis will result in forfeiture of an Eligible Holder’s Subscription Rights. None of the Company, the Rights Offering Subscription Agent, or any of the Backstop Parties will have any liability for any such failure.

No Eligible Holder (except a Backstop Party) shall be entitled to participate in the Rights Offering unless the aggregate Subscription Price for the Rights Offering Securities it subscribes for is received by the Rights Offering Subscription Agent at or prior to Rights Offering Expiration Time.

Backstop Parties and Joining Legacy Parties have already been designated and are known to the Debtors.

Special Note for Backstop Parties. Backstop Parties that hold Notes Claims will receive (through their counsel) an addendum (a “Restricted Access Addendum”), and must arrange for the Restricted Access Addendum to be provided to their Nominee, who will provide the relevant Restricted Access Code (included in the Restricted Access Addendum) to the Subscription Agent when tendering the underlying Notes through ATOP into the Restricted Access Group. Backstop Parties are not required to make payment of the Subscription Price at or prior to Rights Offering Expiration Time, and instead must provide their payment at or prior to the Backstop Escrow Funding Date in accordance with Section 2.4 of the Backstop Commitment Agreement.

The rights and obligations of the Backstop Parties in the Rights Offering shall be governed by the Backstop Commitment Agreement. To the extent the rights or obligations set forth therein differ from the rights and obligations set forth in these Rights Offering Procedures or any Subscription Form, the Backstop Commitment Agreement controls.

Special Note for Joining Legacy Parties with respect to Holdback Securities. Joining Legacy Parties that hold Notes Claims will receive (through their counsel) a Restricted Access Addendum at or prior to the Subscription Commencement Date, and must arrange for the Restricted Access Addendum to be provided to their Nominee, who will provide the relevant Restricted Access Code (included in the Restricted Access Addendum) to the Subscription Agent

11

when tendering the underlying Notes through ATOP into the Restricted Access Group. Joining Legacy Parties must deliver the aggregate Subscription Price for their Holdback Securities to the account provided in the Joining Legacy Party Funding Notice at or prior to the Rights Offering Expiration Time (such date, the “Joining Legacy Party Funding Date”). For the avoidance of doubt, Joining Legacy Parties must separately deliver the aggregate Subscription Price for their Rights Offering Securities subscribed for in the Rights Offering at or prior to the Rights Offering Expiration Time, and are encouraged to coordinate payment of the Subscription Price for such Rights Offering Securities subscribed for in the Rights Offering through their Nominees.

No interest is payable on any advanced funding of the Subscription Price. If the Rights Offering is terminated for any reason, the aggregate Subscription Price previously received by the Rights Offering Subscription Agent will be returned to Eligible Holders as provided in Section 6 herein. No interest will be paid on any returned Subscription Price.

To participate in the Rights Offering, an Eligible Holder must complete all of the steps outlined below at or prior to Rights Offering Expiration Time. If an Eligible Holder does not complete all of the steps outlined below at or prior to Rights Offering Expiration Time, such Eligible Holder shall be deemed to have forever and irrevocably relinquished and waived its right to participate in the Rights Offering; provided that the Backstop Parties (in their capacities as Eligible Holders) shall not be required to pay their respective aggregate Subscription Price until the Backstop Escrow Funding Date in accordance with the terms of the Backstop Commitment Agreement.

Eligible Holders have the right, but not the obligation, to participate in the Rights Offering; provided, however, that Eligible Holders that are Backstop Parties must exercise their Subscription Rights pursuant to the Backstop Commitment Agreement.

Subject to the terms and conditions set forth in the Plan, the Backstop Commitment Agreement, these Rights Offering Procedures, and the Subscription Forms, each Eligible Holder that holds Allowed General Unsecured Claims against Debtor Group B (including Priority Guaranteed Notes Claims) is entitled to subscribe for Second Lien Notes with an aggregate Subscription Price (the “Guaranteed Notes Allocation Subscription Price”) equal to the product of (a) such Eligible Holder’s pro rata share (based on the amount of such participant’s outstanding Allowed General Unsecured Claims against Debtor Group B) and (b) the Guaranteed Notes Allocation, reduced by the Ad Hoc Guaranteed Group Holdback Notes.

Subject to the terms and conditions set forth in the Plan, the Backstop Commitment Agreement, these Rights Offering Procedures, and the Subscription Forms, each Eligible Holder that holds Allowed General Unsecured Claims against Debtor Group C (including Legacy Notes Claims) is entitled to subscribe for Second Lien Notes with an aggregate Subscription Price (the “Legacy Notes Allocation Subscription Price” and, together with the Guaranteed Notes Allocation Subscription Price, the “Aggregate Subscription Price”) equal to the product of (a) such Eligible Holder’s pro rata share (based on the amount of such participant’s outstanding Allowed General Unsecured Claims against Debtor Group C) and (b) the Legacy Notes Allocation, reduced by the Ad Hoc Legacy Group Holdback Notes.

12

The purchase price to be paid by an Eligible Holder for Rights Offering Securities (the “Subscription Price”) shall be the amount of the Aggregate Subscription Price that such Eligible Holder properly elects to pay for Rights Offering Securities pursuant to these Rights Offering Procedures.

Subject to the terms and conditions set forth in the Plan, each participant in the Rights Offering in respect of the Guaranteed Notes Allocation or Legacy Notes Allocation shall receive its corresponding amount of Participation Equity. All such allocations of New Shares will be calculated and rounded down to the nearest whole share.

Eligible Holders are not required to be a qualified institutional buyer within the meaning of Rule 144A of the Securities Act or an institution that is an accredited investor within the meaning of Rule 501(a) under the Securities Act in order to participate in the Rights Offering; provided, however, that to the extent any issuance of Rights Offering Securities to a Holder of Eligible Claims would not qualify for the exemption from registration under the Securities Act provided by Section 1145 of the Bankruptcy Code, such Holder must certify that it is either (a) a qualified institutional buyer; (b) an institution that is an accredited investor; or (c) a non-U.S. person under Regulation S that is located outside of the United States; and, in each case, (d) if established or with a registered office in any member state of the EEA or the United Kingdom, a Permitted EU Person or Permitted UK Person, respectively. For the avoidance of doubt, Joining Legacy Parties must certify that they are an Eligible Holder pursuant to items (a), (b), or (c), and (d) above to subscribe for their pro rata share of Holdback Securities.

There will be no over-subscription privilege in the Rights Offering. Any Rights Offering Securities that have not been duly subscribed for by Eligible Holders in accordance with the Rights Offering Procedures and the Plan (the “Unsubscribed Securities”) will not be offered to other Eligible Holders but the Backstop Parties have committed to subscribe for such Unsubscribed Securities in accordance with the Backstop Commitment Agreement.

Any Eligible Holder that subscribes for Rights Offering Securities and is deemed to be an “underwriter” under Section 1145(b) of the Bankruptcy Code, including affiliates of the Company, will be subject to restrictions under the Securities Act on its ability to resell those securities.

SUBJECT TO THE TERMS AND CONDITIONS OF THESE RIGHTS OFFERING PROCEDURES (AND THE BACKSTOP COMMITMENT AGREEMENT IN THE CASE OF ANY BACKSTOP PARTY), ALL SUBSCRIPTIONS SET FORTH IN THE SUBSCRIPTION FORM ARE IRREVOCABLE.

The Rights Offering will commence and the Subscription Rights will be allocated on the Subscription Commencement Date and will expire at the Rights Offering Expiration Time. Each Eligible Holder intending to subscribe for Rights Offering Securities in the Rights Offering must affirmatively elect to exercise its Subscription Rights in the manner set forth in the Subscription Form at or prior to Rights Offering Expiration Time and must pay for any exercised Subscription Rights at or prior to the applicable deadline.

13

Subject to the terms and conditions set forth herein, and except with respect to the Backstop Parties, any exercise (including payment) of the Subscription Rights after the Rights Offering Expiration Time will not be allowed and any purported exercise (including payment) received by the Rights Offering Subscription Agent after the Rights Offering Expiration Time, regardless of when the documents relating to such exercise were sent, will not be honored.

The Rights Offering Expiration Time may be extended by the Debtors or as required by law.

As more fully described below, in order for an Eligible Holder to acquire Rights Offering Securities in the Rights Offering, at or prior to the Rights Offering Expiration Time:

Although Backstop Parties are not required to pay the Subscription Price at or prior to Rights Offering Expiration Time, if any Backstop Parties hold Notes Claims they are required to deliver a Restricted Access Addendum to their Nominee, who will provide the relevant Restricted Access Code (included in the Restricted Access Addendum) to the Subscription Agent when tendering the underlying Notes through ATOP into the Restricted Access Group.

Joining Legacy Parties holding Notes Claims are required to deliver a Restricted Access Addendum to their Nominee, who will provide the relevant Restricted Access Code (included in the Restricted Access Addendum) to the Subscription Agent when tendering the underlying Notes through ATOP into the Restricted Access Group. Joining Legacy Parties must deliver the aggregate Subscription Price for their Rights Offering Securities subscribed for in the Rights Offering at or prior to the Rights Offering Expiration Time, and are encouraged to coordinate payment of the Subscription Price for such Rights Offering Securities subscribed for in the Rights Offering through their Nominees. Joining Legacy Parties must separately deliver the aggregate Subscription Price for their Holdback Securities to the account provided in the Joining Legacy Party Funding Notice at or prior to the Joining Legacy Party Funding Date.

Each Eligible Holder may exercise all or any portion of such Eligible Holder’s Subscription Rights, subject to the terms and conditions contained herein. In order to facilitate the exercise of the Subscription Rights, beginning on the Subscription Commencement Date, the Subscription Form and these Rights Offering Procedures will be sent to each Eligible Holder, including appropriate instructions for the proper completion, due execution and timely delivery of the executed Subscription Form or, in the case of Notes Claims, delivery of the underlying Notes via ATOP, and the payment of the applicable aggregate Subscription Price for such Eligible Holder’s Rights Offering Securities.

14

Notwithstanding anything to the contrary in these Rights Offering Procedures, Eligible Holders that are Backstop Parties must exercise their Subscription Rights pursuant to the Backstop Commitment Agreement. Subject to the terms and conditions of the Backstop Commitment Agreement, no later than the fifth Business Day following the Rights Offering Expiration Time, the Rights Offering Subscription Agent shall deliver to each Backstop Party a written notice (the “Funding Notice”) of (i) the amount of Rights Offering Securities elected to be subscribed for by the Rights Offering Participants and the aggregate Subscription Price therefor; (ii) the aggregate amount of Holdback Securities to be subscribed for by all Backstop Parties and the aggregate Subscription Price therefor; (iii) the amount of Holdback Securities to be subscribed for by such Backstop Party and the Subscription Price therefor; (iv) the aggregate amount of Unsubscribed Securities (broken down by Guaranteed Notes (and associated Participation Equity) and Legacy Notes (and associated Participation Equity) before and after giving effect to the Legacy Undersubscription Rights), if any, and the aggregate Subscription Price therefor; (v) the amount of Unsubscribed Securities (based upon such Backstop Party’s Backstop Commitment Percentage) to be subscribed for by such Backstop Party and the Subscription Price therefor; and (vi) the escrow account to which such Backstop Party shall deliver and pay the Subscription Price for such Backstop Party’s Rights Offering Securities, Holdback Securities and Backstop Commitment Percentage of the Unsubscribed Securities (the “Backstop Escrow Account”). The Rights Offering Subscription Agent shall promptly provide such written backup, information and documentation relating to the information contained in the Funding Notice as any Backstop Party may reasonably request.

Eligible Holders that are Joining Legacy Parties must exercise their Subscription Rights pursuant to these Rights Offering Procedures; provided that, with respect to such Joining Legacy Parties’ allocation of Holdback Securities, no later than five Business Days prior to the Rights Offering Expiration Time (such date, the “Joining Legacy Parties’ Notice Date”), the Rights Offering Subscription Agent shall deliver to each Joining Legacy Party a written notice (the “Joining Legacy Party Funding Notice”) of (i) the amount of Holdback Securities to be subscribed for by such Joining Legacy Party and the Subscription Price therefor; and (ii) the account to which such Joining Legacy Party shall deliver and pay the Subscription Price for such Joining Legacy Party’s Holdback Securities.

In order to validly exercise its Subscription Rights, an Eligible Holder must:

15

ALL BACKSTOP PARTIES MUST MAKE ALL PAYMENTS TO THE BACKSTOP ESCROW ACCOUNT IN ACCORDANCE WITH THE BACKSTOP COMMITMENT AGREEMENT, AND SHOULD NOT PAY THEIR NOMINEE(S).

WITH RESPECT TO THEIR ALLOCATIONS OF HOLDBACK SECURITIES ONLY, ALL JOINING LEGACY PARTIES MUST MAKE PAYMENTS TO THE APPLICABLE ACCOUNT IN ACCORDANCE WITH THE JOINING LEGACY PARTY FUNDING NOTICE AND THESE RIGHTS OFFERING PROCEDURES, AND SHOULD NOT PAY THEIR NOMINEE(S).

16

Delivery of the Subscription Form. Holders of Non-Notes Claims may deliver their Subscription Form to the Rights Offering Subscription Agent by either physical delivery or by electronic mail in accordance with the address information for the Rights Offering Subscription Agent set forth on the Subscription Form. In all cases, the Subscription Form must actually be received by the Rights Offering Subscription Agent at or prior to the Rights Offering Expiration Time.

For holders of Non-Notes Claims, the method of delivery of the applicable Subscription Form and any other required documents is at each Eligible Holder’s option and sole risk, and delivery will be considered made only when actually received by the Rights Offering Subscription Agent. If delivery is by mail, registered mail with return receipt requested, properly insured, is encouraged and strongly recommended. In all cases, you should allow sufficient time to ensure timely delivery at or prior to 5:00 p.m. New York City Time on the Rights Offering Expiration Time.

Holders of Notes Claims must deliver their Subscription Form to their Nominee (and otherwise follow the instructions of their Nominee) and instruct their Nominee to tender their Notes to the account of the Rights Offering Subscription Agent in accordance with DTC’s ATOP procedures, each in sufficient time for their Nominee to tender their Notes to the Rights Offering Subscription Agent at or prior to the Rights Offering Expiration Time.

Payment of the Subscription Price. Payment of the Subscription Price, must be made by wire transfer of immediately available funds to the account of the Rights Offering Subscription Agent. Other than in the case of Backstop Parties, the funds must be received in the account of the Rights Offering Subscription Agent at or prior to the Rights Offering Expiration Time.

In the event that the funds received by the Rights Offering Subscription Agent from any Eligible Holder (other than a Backstop Party) do not correspond to the applicable Subscription Price payable for the Rights Offering Securities elected to be subscribed for by such Eligible Holder, the amount of the Rights Offering Securities deemed to be subscribed for such Eligible Holder will be the lesser of (a) the amount of the Rights Offering Securities elected to be subscribed for by such Eligible Holder as evidenced by the relevant Subscription Form and (b) the amount of the Rights Offering Securities that correspond to the funds received, in each case rounded in accordance with Section 8 hereof; provided that the amount of Rights Offering Securities deemed to be subscribed for will not be greater than such amount of Rights Offering Securities allocable to such Holder’s Aggregate Subscription Price.

The cash paid to the Rights Offering Subscription Agent in accordance with these Rights Offering Procedures will be deposited and held by the Rights Offering Subscription Agent in a segregated account established pursuant to an agreement in form and substance reasonably satisfactory to the Requisite Backstop Parties and the Debtors, until released in connection with the settlement of the Rights Offering on the Effective Date. The Rights Offering Subscription Agent may not use such cash for any other purpose prior to the Effective Date and may not encumber or permit such cash to be encumbered with any lien or similar encumbrance. The cash held by the Rights Offering Subscription Agent hereunder shall not be deemed part of the Debtors’ bankruptcy estates.

17

Tender of Notes. Eligible Holders that hold Notes Claims and that exercise their Subscription Rights are required to cause their Nominees to tender their Notes to an account of the Rights Offering Subscription Agent in accordance with DTC’s ATOP procedures. If the Holder exercises its Subscription Rights only in part, then, for purposes of participation in the Rights Offering, the Holder is only required to tender its Notes in proportion to the Subscription Rights being exercised. If the Holder holds Notes in more than one class or series, and is exercising its Subscription Rights, the tender of Notes in each class or series must be in proportion to the Subscription Rights being exercised in respect of the corresponding Notes Claims.

Unless the Effective Date has occurred, the Rights Offering will be deemed automatically terminated without any action of any party upon the earliest of (a) termination of the Plan or rejection of the Plan by all classes entitled to vote, (b) termination of the Restructuring Support Agreement in accordance with its terms, (c) termination of the Backstop Commitment Agreement in accordance with its terms and (d) the Outside Date (as defined in the Backstop Commitment Agreement and as may be extended pursuant to the terms of the Backstop Commitment Agreement). In the event the Rights Offering is terminated, any payments received

18

pursuant to these Rights Offering Procedures will be returned, without interest, to the applicable Eligible Holder or relevant payee as soon as reasonably practicable, but in any event within three Business Days after the date of termination, and, in the case of payments made in respect of Notes held through a Nominee, the Notes will be returned to the Nominee that submitted them through ATOP.

The settlement of the Rights Offering is conditioned on confirmation of the Plan by the Bankruptcy Court and the occurrence of the Effective Date. The Debtors intend that the Rights Offering Securities will be issued to the Eligible Holders in book-entry form, and that DTC, or its nominee, will be the holder of record of such Rights Offering Securities. To the extent DTC is unwilling or unable to make the Rights Offering Securities eligible on the DTC system, or the Debtors determine in their sole discretion not to make the Rights Offering Securities eligible on the DTC system, the Rights Offering Securities will be issued directly to the Eligible Holders or their respective Nominees (whether in book-entry form or otherwise).

All allocations with respect to the Second Lien Notes will be calculated and rounded down to the nearest minimum denomination of $1.00 and integral multiples of $1.00 in excess thereof, as applicable.

No fractional New Shares will be issued in the Rights Offering. All share allocations will be calculated and rounded down to the nearest whole share. No compensation shall be paid, whether in cash or otherwise, in respect of any rounded-down amounts.

All questions concerning the timeliness, viability, form and eligibility of any exercise of Subscription Rights will be determined in good faith by the Debtors in consultation with the Requisite Backstop Parties, and, if necessary, subject to a final and binding determination by the Bankruptcy Court. Subject to the foregoing, the Debtors, with the consent of the Requisite Backstop Parties, may waive or reject any defect or irregularity in, or permit such defect or irregularity to be corrected within such time as they may determine in good faith, the purported exercise of any Subscription Rights. Subscriptions will be deemed not to have been received or accepted until all irregularities have been waived or cured within such time as the Debtors determine in good faith in consultation with the Requisite Backstop Parties. In addition, the Rights Offering Subscription Agent shall have no obligation to notify parties of or cure any defects to the forms returned in exercising the Subscription Rights.

Before exercising any Subscription Rights, Eligible Holders should carefully read the Disclosure Statement and the Plan in their entirety for information relating to the Debtors and the risk factors to be considered.

19

All calculations, including, to the extent applicable, the calculation of (a) the value of any Eligible Holder’s Allowed General Unsecured Claims against Debtor Group B or Allowed General Unsecured Claims against Debtor Group C for the purposes of the Rights Offering and (b) any Eligible Holder’s Rights Offering Securities, shall be made in good faith by the Debtors and in accordance with any claim amounts included in the Plan, and any disputes regarding such calculations shall be subject to a final and binding determination by the Bankruptcy Court.

With the prior written consent of the Requisite Backstop Parties, the Debtors reserve the right to modify these Rights Offering Procedures, or adopt additional procedures consistent with these Rights Offering Procedures, to effectuate the Rights Offering and to issue the Rights Offering Securities. Any update reflecting material modifications to these Rights Offering Procedures made after the Subscription Commencement Date will be promptly posted to the Debtors’ restructuring website at https://dm.epiq11.com/noble and provided to DTC via email. In so doing, and subject to the consent of the Requisite Backstop Parties, the Debtors may execute and enter into agreements and take further action that the Debtors determine in good faith is necessary and appropriate to effectuate and implement the Rights Offering and the issuance of the Rights Offering Securities.

The Debtors reserve the right to request additional information from any participant in the Rights Offering to confirm that such participant is an Eligible Holder.

The Notes are held in book-entry form in accordance with the practices and procedures of DTC. The Debtors intend to comply with the practices and procedures of DTC for the purpose of conducting the Rights Offering with respect to the Notes, and, subject to compliance with the requirements for modifications set forth in Section 10 hereof, these Rights Offering Procedures will be deemed appropriately modified to achieve such compliance.

Without limiting the foregoing, the Debtors intend that, to the extent practicable, and unless otherwise determined by the Debtors, the Rights Offering Securities will be issued in book entry form, and that DTC, or its nominee, will be the holder of record of such Rights Offering Securities. The ownership interest of each holder of such Rights Offering Securities, and transfers of ownership interests therein, is expected to be recorded on the records of the direct and indirect participants in DTC. Notwithstanding anything herein to the contrary, the Debtors will continue to evaluate potential alternative securities law and transfer restriction treatment for the Rights Offering Securities issued pursuant to these Rights Offering Procedures, with a view toward maximizing the liquidity and fungibility of the issuances of the Rights Offering Securities. Such alternative treatment shall be reasonably satisfactory to the Issuers and the Requisite Backstop Parties.

Holders of Non-Notes Claims that subscribe for Rights Offering Securities can designate on their Subscription Form a Nominee with whom they have a securities account, and elect to receive the Rights Offering Securities by book-entry credit, to the extent available, via Deposit or Withdrawal At Custodian (“DWAC”) deposit to a DTC participant account of that Nominee (or that Nominee’s DTC participant), which DWAC deposit must be coordinated by such holder when directed to do so by the Rights Offering Subscription Agent.

20

The Rights Offering Instructions for Eligible Holders attached hereto should be carefully read and strictly followed by the Eligible Holders.

Questions relating to the Rights Offering should be directed to the Rights Offering Subscription Agent at [___________]. Please note that the Rights Offering Subscription Agent is only able to respond to procedural questions regarding the Rights Offering, and cannot provide any information beyond that included in these Rights Offering Procedures and the Subscription Forms. If applicable, an Eligible Holder must follow the directions of its Nominee with respect to providing instructions to it in connection with the Rights Offering.

The risk of non-delivery of any instructions, documents, and payments to any Nominee or to the Rights Offering Subscription Agent is on the Eligible Holder electing to exercise its Subscription Rights and not the Debtors, the Rights Offering Subscription Agent, or the Backstop Parties.

Unexercised Subscription Rights in respect of Rights Offering Securities will be forever and irrevocably relinquished on the Rights Offering Expiration Time. If, at or prior to the Rights Offering Expiration Time, the Rights Offering Subscription Agent for any reason does not receive (x) from (a) an Eligible Holder of Non-Notes Claims a duly completed and executed applicable Subscription Form (with accompanying IRS Form W-9 or appropriate IRS Form W-8, as applicable), or (b) an Eligible Holder of Notes Claims the tender of such holder’s underlying Notes through ATOP and, (y) in the case of a non-Backstop Party, payment of the Subscription Price, such Eligible Holder shall be deemed to have forever and irrevocably relinquished and waived its right to participate in the Rights Offering in respect of Rights Offering Securities.

Subject to the terms and conditions set forth herein and in the Backstop Commitment Agreement, any attempt to exercise Rights after the Rights Offering Expiration Time in respect of Rights Offering Securities shall be null and void and the Debtors shall not be obligated to honor any such purported exercise received by the Rights Offering Subscription Agent after the Rights Offering Expiration Time regardless of when the documents relating thereto were sent.

The method of delivery of the applicable Subscription Form and/or any other required documents is at each Eligible Holder’s option and sole risk. In all cases, you should allow sufficient time to ensure timely delivery of the applicable Subscription Form (in the case of a Non-Notes Claim) or underlying Notes via ATOP (in the case of a Notes Claim) at or prior to 5:00 p.m. New York City Time on the Rights Offering Expiration Time. Eligible Holders of Notes Claims must ensure that their Nominee tenders their Notes at or prior to Rights Offering Expiration Time and coordinate timely payment of the Subscription Price.
