 19 












 (b) Subscription Covenant. On and subject to the terms and conditions hereof,
including entry of the Confirmation Order, each Backstop Party agrees, severally and not jointly, to fully exercise all Rights that are issued to it pursuant to the Rights Offering and duly subscribe for all Rights Offering Securities issuable to it
in relation thereto, in accordance with the Rights Offering Procedures and the Plan, provided that notwithstanding anything to the contrary herein or therein, payment for such Rights Offering Securities shall be made in accordance with
Section 2.4(b) below. Any Defaulting Backstop Party shall be liable, severally and not jointly, to each non-Defaulting Backstop Party, the Debtors and the Issuers as a result of any breach of its obligations hereunder. 

(c) If reasonably requested by the Requisite Backstop Parties, from time to time prior to the expiration of the Offering Period, the Company or
the Issuers (as applicable) shall notify, or instruct the Rights Offering Subscription Agent to notify, as promptly as practicable and in any event, will instruct the Rights Offering Subscription Agent to provide within two (2) Business Days of
receipt of such request by the Company or the Issuers (as applicable), the Backstop Parties of the aggregate number of Rights known by the Company or the Rights Offering Subscription Agent to have been exercised pursuant to the Rights Offering as of
the most recent practicable time before such request. 
 (d) The Rights Offering Securities will be issued in reliance on the exemption from
registration under 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 in reliance on the exemption from registration provided by
Section 4(a)(2) under the Securities Act or another available exemption, and the Plan and the Disclosure Statement shall each include a statement to such effect. The subscription and issuance of the Unsubscribed Securities and, if applicable,

Section 2.2 The Backstop Commitment. 

(a) On and subject to the terms and conditions hereof, including entry of the BCA Approval Order and the Confirmation Order, each Backstop
Party agrees, severally and not jointly, to subscribe for, and the Parent Issuer and the Subsidiary Issuer, as applicable, shall issue to such Backstop Party, on the Closing Date at the applicable Subscription Price, the amount of Unsubscribed
Securities equal to such Backstop Party’s Backstop Commitment Percentage of the aggregate Unsubscribed Securities under (i) the Guaranteed Notes Allocation (in the case of the Ad Hoc Guaranteed Group Backstop Parties) or (ii) the
Legacy Notes Allocation (in the case of the Ad Hoc Legacy Group Backstop Parties), in accordance with this Agreement (such obligation to subscribe for the Unsubscribed Securities, the “Backstop Commitment”); provided,
however, that in no event shall any rounding of Unsubscribed Securities to be subscribed for by the Backstop Parties solely to avoid fractional interests cause the aggregate Subscription Price for the Rights Offering Securities to be less
than Two Hundred Million Dollars ($200,000,000). Notwithstanding anything to the contrary contained herein, in connection with any undersubscription of the Guaranteed Notes Allocation, the Ad Hoc Legacy Group Backstop Parties shall have the
exclusive right (but not the obligation) (the “Legacy Undersubscription Rights”) to subscribe for, upon the expiration of the Offering Period, the first Six Million Dollars ($6,000,000) of Unsubscribed Securities that were
unsubscribed under the Guaranteed Notes Allocation, pro rata based on their respective Backstop Commitment Percentages (as among the Ad Hoc Legacy Group Backstop Parties only), before the Ad Hoc Guaranteed Group Backstop Parties are required
to subscribe for such Unsubscribed Securities pursuant to the Backstop Commitment.

 (b) On and subject to the terms and conditions hereof, including entry of the BCA Approval
Order and the Confirmation Order, each Backstop Party agrees, severally and not jointly, to subscribe for, and the Parent Issuer and the Subsidiary Issuer, as applicable, shall issue to such Backstop Party, on the Closing Date for the applicable

Group Holdback Shares (in the case of the Ad Hoc Guaranteed Group Backstop Parties) and (ii) the Ad Hoc Legacy Group Holdback Notes and the Ad Hoc Legacy Group Holdback Shares (in the case of the Ad Hoc Legacy Group Backstop Parties), in
accordance with the Plan (such obligation to subscribe for the Holdback Securities, the “Holdback Commitment”). Each Backstop Party acknowledges and agrees that withholding may apply to any Backstop Party that receives
Holdback Securities but cannot provide the Company with a duly executed IRS Form W-9, unless such Backstop Party executes and delivers an indemnification agreement in favor of the Company in a form reasonably
acceptable to the Company and the applicable Backstop Parties.

Party that is a Defaulting Backstop Party) shall have the right, but shall not be obligated, within five (5) Business Days after receipt of written notice from the Company or the Issuers (as applicable) to the Ad Hoc Guaranteed Group Backstop
Parties of such Backstop Party Default (which notice shall be given promptly following the occurrence of such Backstop Party Default) (such five (5) Business Day period, the “Guaranteed Backstop Party Replacement
Period”), to make arrangements for one or more of the Ad Hoc Guaranteed Group Backstop Parties (other than any Ad Hoc Guaranteed Group Backstop Party that is a Defaulting Backstop Party) to subscribe for all or any portion of the

Percentage of any such member of the Ad Hoc Guaranteed Group (as among the Ad Hoc Guaranteed Group Backstop Parties only) or as may otherwise be agreed upon by the Ad Hoc Guaranteed Group Backstop Parties electing to subscribe for all or any portion
of the Available Securities (such Backstop Parties, the “Guaranteed Replacing Backstop Parties”); or 
 (ii) by an Ad
Hoc Legacy Group Backstop Party, the Ad Hoc Legacy Group Backstop Parties (other than any Ad Hoc Legacy Group Backstop Party that is a Defaulting Backstop Party) shall have the right, but shall not be obligated to, within five (5) Business Days
after receipt of written notice from the Company to all Ad Hoc Legacy Group Backstop Parties of such Backstop Party Default (which notice shall be given promptly following the occurrence of such Backstop Party Default) (such five (5) Business
Day period, the “Legacy Backstop Party  

  
 21 












 
Replacement Period”), to make arrangements for one or more of the Ad Hoc Legacy Group Backstop Parties (other than any Ad Hoc Legacy Group Backstop Party that is a Defaulting
Backstop Party) to subscribe for all or any portion of the Available Securities (such subscription, a “Legacy Backstop Party Replacement”) on the terms and subject to the conditions set forth in this Agreement and in such

collectively, the “Replacing Backstop Parties”). 
 Any such Available Securities subscribed for by a Replacing
Backstop Party shall be (1) included in the determination of (x) the Backstop Securities and the Holdback Securities of such Replacing Backstop Party for all purposes hereunder and (y) the Backstop Commitment Percentage of such
Replacing Backstop Party for purposes of Section 3.1 and (2) excluded from the determination of (x) the Backstop Securities and the Holdback Securities of the applicable Defaulting Backstop Party for all purposes

allow for (A) the Guaranteed Backstop Party Replacement and/or the Legacy Backstop Party Replacement, as applicable, to be completed within the Guaranteed Backstop Party Replacement Period or the Legacy Backstop Party Replacement Period, as
applicable, or (B) the consummation of a Cover Transaction within the Cover Transaction Period. 
 (b) If a Backstop Party is or becomes
a Defaulting Backstop Party, it shall (i) not be entitled to any of the Backstop Premiums hereunder, (ii) promptly notify the Company and the Issuers (as applicable) in writing if it received any portion of the Backstop Premium, and
(iii) transfer its portion of the Backstop Premiums to the extent received from the Company or the Issuers (as applicable) (x) if a Guaranteed Backstop Party Replacement and/or a Legacy Backstop Party Replacement or (y) if a Cover
Transaction has been consummated, to the Replacing Backstop Parties or Cover Subscribers (as applicable) pro rata based upon the amount of Available Securities subscribed for by each such Replacing Backstop Party or Cover Subscriber within one
(1) Business Day of receiving written notice by the Company, the Issuers or any other Backstop Party of the consummation of such Guaranteed Backstop Party Replacement and/or Legacy Backstop Party Replacement, as applicable, or of such Cover
Transaction. 
 (c) Nothing in this Agreement shall be deemed to require a Backstop Party to subscribe for more than its Backstop Commitment
Percentage of (i) the Unsubscribed Securities or (ii) the Holdback Securities. 
 (d) Notwithstanding the foregoing, if the non-Defaulting Backstop Parties do not elect to subscribe for all of the Available Securities pursuant to Section 2.3(a) prior to the expiration of the Guaranteed Backstop Party Replacement
Period or the Legacy Backstop Party Replacement Period, as applicable, the Company or the Issuers (as applicable) shall have an additional fifteen (15) Business Days following the expiration thereof (such period, the “Cover
Transaction Period”) to consummate a Cover Transaction. 

  
 22 












 (e) For the avoidance of doubt, notwithstanding anything to the contrary set forth in
Section 9.1(d)(iii) or Section 9.2 but subject to Section 10.10, no provision of this Agreement shall relieve any Defaulting Backstop Party from liability
hereunder in connection with such Defaulting Backstop Party’s Backstop Party Default.

(b) Backstop Escrow Account Funding. On or prior to the date that is three (3) Business Days prior to the Effective Date,

Section 2.6) against payment of the aggregate Subscription Price for the Backstop Securities, the Holdback Securities and the Rights Offering Securities of such Backstop Party. Unless a Backstop Party requests delivery of a
physical stock certificate, the entry of any New Shares to be delivered pursuant to this Section 2.5(d) into the account of a Backstop Party pursuant to the Parent Issuer’s book entry procedures and delivery to such
Backstop Party of an account statement reflecting the book entry of such New Shares shall be deemed delivery of such New Shares for purposes of this Agreement, and the delivery of any New Shares to be delivered pursuant to this
Section 2.5(d) to an account of a Backstop Party pursuant to DTC procedures shall be deemed delivery of such New Shares for purposes of this Agreement.

the Closing Date that some or all of its Backstop Securities, Holdback Securities and/or right to any Backstop Premium be issued in the name of, and delivered to, one or more of its Affiliates (each a “Related

Backstop Party’s ability to Transfer any of its Second Lien Notes or New Shares or any interest therein; provided, that any such Transfer shall be made in accordance with the Securities Act and applicable securities Laws.

treated for U.S. federal income tax purposes as paid by the Debtors in exchange for the issuance of a put right to the Debtors with respect to the Rights Offering (and the Parties shall not take any position on any applicable U.S. federal, state or
local tax return inconsistent with such treatment). 
 Section 3.3 Expense Reimbursement. Whether or not the transactions
contemplated hereunder are consummated, the Debtors agree to pay (without duplication) the documented reasonable third-party and out-of-pocket fees and expenses of each
Backstop Party (other than any Defaulting Backstop Party), including the documented reasonable fees and expenses of counsel and other professionals retained by such Backstop Party but excluding any value-added, goods and services, sales or other
similar Tax (“VAT”) that is recoverable (whether

Reimbursement”) and (c) such other advisors for each of the Ad Hoc Guaranteed Group and the Ad Hoc Legacy Group as may be reasonably required. The Expense Reimbursement accrued through the date on which the BCA Approval Order is
entered shall be paid as soon as practicable thereafter, and in any event within two (2) Business Days thereof. The Expense Reimbursement shall thereafter be payable in cash by the Debtors on a monthly basis. Following the last Business Day of
each calendar month following the month in which the BCA Approval Order has been entered by the Bankruptcy Court, the Backstop Parties shall deliver to the Debtors a written and reasonably documented (subject to redaction to preserve attorney client
and work product privileges) invoice for their reimbursable fees and expenses; provided that the invoice for such fees and expenses shall not be required to comply with U.S. Trustee guidelines and local guidelines issued by the Bankruptcy
Court with respect to payment of professional fees and may be in a summary form only (which shall not be required to contain time entries and which may be redacted or modified to the extent necessary to delete any information subject to the
attorney-client privilege, any information constituting attorney work product, or any other confidential information and the provision of such summary invoices shall not constitute any waiver of the attorney-client privilege or any benefits of the
attorney work product doctrine). The Debtors shall pay such invoices within ten (10) Business Days of receipt thereof. For the avoidance of doubt, no recipient of any payment under this Section 3.3 shall be required to
file with respect thereto any interim or final fee application with the Bankruptcy Court. The provisions for the payment of the Expense Reimbursement 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, and the Expense Reimbursement shall an constitute allowed administrative expense of the Debtors’ estates under Sections 503(b) and 507 of the Bankruptcy Code.

or affecting creditors’ rights and to general principles of equity whether applied in a court of law or a court of equity, except where the failure to be valid, binding or enforceable would not reasonably be expected to result in a Material
Adverse Change. No written notice to terminate, in whole or part, any Material Contract has been delivered to the Company or any of the other Debtors except where such termination would not reasonably be expected to result in a Material Adverse
Change. Other than as a result of the filing of the Chapter 11 Cases, neither the Company nor any of the other Debtors nor, to the Knowledge of the Company, any other party to any Material Contract, is in default or breach under the terms thereof

endeavors to: (i) promptly notify each other of, and if in writing, furnish each other with copies of (or, in the case of material oral communications, advise each other orally of) any communications from or with an Antitrust and Foreign
Investment Authority, subject to confidentiality obligations and the need to protect business secrets; (ii) where reasonably practicable, not participate in any meeting with an Antitrust and Foreign Investment Authority unless it consults with

opportunity to attend and participate thereat; (iii) furnish each other Filing Party and the Company, as applicable, with copies of all correspondence, filings and communications between such Filing Party or the Company and the Antitrust and

other Filing Party and the Company, as applicable, of any material correspondence, filings and communications with any Antitrust and Foreign Investment Authority; and (vi) not withdraw its filing, if any, under the HSR Act, the DPA or any other
filing to any Antitrust and Foreign Investment Authority without the prior written consent of the Requisite Backstop Parties and the Company (not to be unreasonably withheld, conditioned or delayed). 

  
 51 












 (c) Should a Filing Party be subject to an obligation in connection with any Antitrust and
Foreign Investment Approval to jointly notify with one or more other Filing Parties (each, a “Joint Filing Party”) a transaction contemplated by this Agreement, the Plan or the other Transaction Agreements, such Joint Filing
Party shall promptly notify each other Joint Filing Party of, and if in writing, furnish each other Joint Filing Party with copies of (or, in the case of material oral communications, advise each other Joint Filing Party orally of) any
communications from or with an Antitrust and Foreign Investment Authority, subject to confidentiality obligations and the need to protect business secrets. 

(d) Subject to the last sentence of this Section 6.5(d) and to Section 6.5(e), the Company
and each Filing Party shall use commercially reasonable efforts to cause the review or waiting periods under the applicable Antitrust and Foreign Investment Laws to terminate or expire, or to obtain approval from the applicable Antitrust and Foreign
Investment Authority, at the earliest possible date after the date of filing. The communications contemplated by this Section 6.5 may be made by the Company or a Filing Party on an outside counsel-only basis or subject to
other agreed upon confidentiality safeguards. The obligations in this Section 6.5 shall not apply to filings, correspondence, communications or meetings with Antitrust and Foreign Investment Authorities unrelated to the
transactions contemplated by this Agreement, the Plan and the other Transaction Agreements. 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. 

(e) Notwithstanding anything in this Agreement to the contrary, nothing shall require any Backstop Party or any of its Affiliates to
(i) dispose of, license or hold separate any of its or its Subsidiaries’ or Affiliates’ assets, (ii) limit its freedom of action or the conduct of its or its Subsidiaries’ or Affiliates’ businesses or make any other
behavioral commitments with respect to itself or any of its Subsidiaries or Affiliates, (iii) divest any of its Subsidiaries or its Affiliates, or (iv) commit or agree to any of the foregoing. 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. 

Section 6.6 Access to Information. Upon reasonable notice during the Pre-Closing
Period, the Debtors shall afford the Backstop Parties and their Representatives reasonable access (subject to any reasonable restrictions imposed by the Debtors with respect to in-person access in light of COVID-19 concerns), during normal business hours and without unreasonable disruption or interference with Debtors’ business or operations, to the Debtors’ employees, properties, books, contracts and
records and, during the Pre-Closing Period, the Debtors shall furnish promptly to such parties all reasonable information concerning the Debtors’ business, properties and personnel as may reasonably be
requested by any such party, provided that the foregoing shall not require the Company (a) to permit any inspection, or to disclose any information, that in the reasonable judgment of the Company would cause the Company or any of the
other Debtors to violate any of their respective obligations with respect to confidentiality to a third party if the Company shall have used its commercially reasonable efforts to obtain, but failed to obtain, the consent of such third party to such
inspection or disclosure, (b) to disclose any legally privileged information of the Company or any of the other Debtors or (c) to violate any applicable Laws; provided further that the Company shall deliver to the Backstop
Parties a schedule setting forth a description of any requested information not provided to the Backstop Parties pursuant to clauses (a), (b) and (c) above (in the case of clause (a), to the extent not prohibited from doing so by Law or
contractual obligation, provided that, in such case, the Company shall provide a reasonably detailed description of the applicable information to the extent not prohibited by Law or contractual obligation). 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 6.11 New Board of Directors. On the
Closing Date, the board of directors of the Parent Issuer shall be comprised of nine (9) directors consisting of: (i) the chief executive officer of the Parent Issuer; (ii) six (6) directors designated by the members of the Ad Hoc
Guaranteed Group; and (iii) two (2) directors to be designated by the members of the Ad Hoc Legacy Group. 

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.

abandoned at any time prior to the Closing Date: 
 (a) by mutual written consent of the Company and the Requisite Backstop Parties. 

(b) by the Company, the Requisite Guaranteed Backstop Parties or the Requisite Legacy Backstop Parties upon written notice to the Backstop
Parties (in the case of the Company) or to the Company (in the case of the Requisite Guaranteed Backstop Parties or the Requisite Legacy Backstop Parties) if: 

(i) the Closing Date has not occurred by the date that is one hundred eighty (180) days after the Support Date (the
“Initial Outside Date” and, as it may be extended pursuant to this Section 9.1(b)(i), the “Outside Date”); provided, however, that (A) upon
the occurrence of a Backstop Party Default, the Outside Date shall be extended in accordance with Section 2.3(a) and (B) if on the Initial Outside Date the condition set forth in
Section 7.1(j) has not been satisfied (provided that all of the other conditions set forth in Section 7.1 have been or are capable of being satisfied on or prior to the Initial Outside
Date), the Initial Outside Date shall automatically be extended, for so long as the Company or Issuer, as applicable, is using good faith diligent efforts to satisfy the condition set forth in Section 7.1(j), through the
date that such condition is satisfied, provided that in no event shall the Initial Outside Date be extended longer than sixty (60) days; provided, further that no Party shall have the right to terminate this Agreement
pursuant to this Section 9.1(b)(i) if the failure of the Closing to occur on or before the Outside Date was primarily caused by such Party then being in willful or intentional material breach of this
Agreement; 
 (ii) any of the BCA Approval Order, the Disclosure Statement Order or the Confirmation Order is reversed,
stayed, dismissed, vacated, reconsidered or is modified or amended after entry without the prior written consent of the Requisite Backstop Parties (such consent not to be unreasonably withheld, conditioned or delayed); or 

(iii) the Restructuring Support Agreement has been terminated. 

(c) by the Requisite Guaranteed Backstop Parties or the Requisite Legacy Backstop Parties upon written notice to the Company if: 

(i) the failure to comply with a Milestone set forth in the Restructuring Support Agreement, as may be modified, waived or

 66 












 
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); 

(iii) the Company or the other Debtors shall have breached any representation, warranty, covenant or other agreement made by
the Company or the other Debtors in this Agreement or any such representation and warranty shall have become inaccurate after the date of this Agreement, such breach or inaccuracy would, individually or in the aggregate, cause a condition set forth
in Section 7.1(m), (r) or (s) not to be satisfied, and such breach or inaccuracy is not cured by the Company or the other Debtors by the tenth (10th)
Business Day after the giving of notice thereof to the Company by any Backstop Party; provided that the Requisite Backstop Parties shall not have the right to terminate this Agreement pursuant to this
Section 9.1(c)(iii) if one or more Backstop Parties making up the Requisite Backstop Parties is then in breach of any representation, warranty, covenant or other agreement hereunder that would result in the failure of any
condition set forth in Section 7.3(h) or (i) to be satisfied; 
 (iv) an
“Event of Default” under and as defined in any debtor-in-possession credit facility or similar arrangement entered into in connection with the Chapter 11 Cases
has occurred and is continuing unwaived for more than three (3) Business Days; 
 (v) any Debtor files any motion or
pleading with the Bankruptcy Court that is inconsistent with this Agreement and such motion or pleading has not been revoked before the earlier of (A) three (3) Business Days after the Company receives written notice pursuant to this Article
IX that such motion or pleading is inconsistent with this Agreement or the Plan and (B) entry of an order of the Bankruptcy Court approving such motion or pleading. 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. 
 (d) by the Company upon written notice to each Backstop Party if: 

(i) subject to the right of the Backstop Parties to arrange a Guaranteed Backstop Party Replacement and/or a Legacy Backstop
Party Replacement, as applicable in accordance with Section 2.3(a), any Backstop Party shall have breached any representation, warranty, covenant or other agreement made by such Backstop Party in this Agreement or any such
representation and warranty shall have become inaccurate after the date of this Agreement, such breach or inaccuracy would, individually or in the aggregate, cause a condition set forth in Section 7.3(h) or
(i) not to be satisfied, and such breach or inaccuracy is not cured by such Backstop Party by the tenth (10th) Business Day after the giving of notice thereof to such
Backstop Party by the Company; provided that the Company shall not have the right to terminate this Agreement pursuant to this Section 9.1(d)(i) if it is then in breach of any representation, warranty,
covenant or other agreement hereunder that would result in the failure of any condition set forth in Section 7.1(m), (r) or (s) to be satisfied; 

(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 

(iii) a Guaranteed Backstop Party Replacement and/or a Legacy Backstop Party Replacement has not been completed within the
Guaranteed Backstop Party Replacement Period or the Legacy Backstop Party Replacement Period, as applicable, and a Cover Transaction has not been completed within the Cover Transaction Period, in each case, in accordance with
Section 2.3. 
 Section 9.2 Effect of Termination. 

(a) Within three (3) days following the delivery of a termination notice pursuant to Article IX (the
“Termination Notice Period”) the Debtors and/or the Requisite Backstop Parties, as applicable, delivering such termination notice may waive, in writing, the occurrence of the termination event identified in the termination
notice; provided, however, that the termination event provided for in Section 9.1(b)(i) may not be waived beyond the Outside Date with respect to a Backstop Party that does not provide such
waiver. 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. 

(b) A termination payment in an aggregate amount equal to Ten Million Dollars ($10,000,000) (inclusive of any VAT) (the
“Termination Payment”), free and clear of any withholding or deduction (except as required by applicable Law) for any applicable Taxes, shall be paid or caused to be paid by the Debtors in cash by wire transfer of immediately
available funds to the Backstop Parties, or their designees, in accordance with their respective Backstop Commitment Percentages, (i) no later than two (2) Business Days following termination of this Agreement, if this Agreement is
terminated pursuant to Section 9.1(b)(i) by the Debtors (unless, in the case of Section 9.1(b)(i), the Debtors terminate this Agreement at least two hundred forty
(240) days after the Support Date, in which case no Termination Payment shall be payable), Section 9.1(b)(iii) (due to a termination of the Restructuring Support Agreement pursuant to Section 8(a)(i), 8(a)(v),
8(a)(vi), 8(a)(ix), 8(a)(x), 8(a)(xii), 8(a)(xvii), 8(a)(xviii), or 8(b)(v) thereof (unless, in the case of Section 8(b)(v) thereof, the Debtors terminate this Agreement at least two hundred forty (240) days after the Support Date, in
which case no Termination Payment shall be payable)), Section 9.1(c)(ii)(A) or (C), Section 9.1(c)(iii) or Section 9.1(c)(v) or (ii) immediately upon the
consummation of an Alternative Transaction, if this Agreement is terminated pursuant to Section 9.1(b)(iii) (due to a termination of the Restructuring Support Agreement pursuant to Section 8(a)(vii)(B), 8(a)(viii) or
8(b)(ii) thereof) or Section 9.1(c)(iv). 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.

 72 












 
provided, that the sole remedy for any Backstop Party that does not consent to any of the matters referred to in clauses (ii), (iii) or (iv) above shall be that such Backstop Party
shall have the right to terminate its Backstop Commitment as to itself only. The terms and conditions of this Agreement (other than the conditions set forth in Sections 7.1 and 7.3, the waiver of which shall be governed solely by
Article VII) may be waived (x) by the Debtors only by a written instrument executed by the Company and (y) by the Requisite Backstop Parties only by a written instrument executed by all of the Requisite Backstop Parties.
Notwithstanding anything to the contrary contained in this Agreement, the Backstop Parties may agree, among themselves, to reallocate their Backstop Commitment Percentages, without any consent or approval of any other Party; provided,

obligations hereunder immediately prior to such reallocation (including with respect to its Backstop Commitment and Holdback Commitment) in connection with any such reallocation and (iii) the Backstop Parties shall provide written notice to the
Company of any such adjustment reasonably promptly after any such agreement is reached and in any event, within two (2) Business Days of any such agreement. No delay on the part of any Party in exercising any right, power or privilege pursuant
to this Agreement will operate as a waiver thereof, nor will any waiver on the part of any Party of any right, power or privilege pursuant to this Agreement, nor will any single or partial exercise of any right, power or privilege pursuant to this
Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement. Except as otherwise provided in this Agreement, the rights and remedies provided pursuant to this Agreement

 Exhibit A 

NOBLE CORPORATION PLC, ET AL. 

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: 
  

	 	•	 	 The parties entitled to participate in the Rights Offering (the “Eligible Holders”) are Holders
of the following Claims (collectively, the “Eligible Claims”): 


  

	 	•	 	 Allowed General Unsecured Claims against Debtor Group B as of the Record Date (as defined below); and



  

	 	•	 	 Allowed General Unsecured Claims against Debtor Group C as of the Record Date; provided that no Record
Date shall apply to the Notes Claims (as defined below). 


  

 

	1 	 Capitalized terms used and not defined herein shall have the meaning ascribed to them in the Debtors’
Second Amended Joint Plan of Reorganization of Noble Corporation plc and Its Debtor Affiliates [Docket No. 529] (as may be amended from time to time in accordance with its terms, the “Plan”) or the Backstop Commitment Agreement (as
defined in the Plan). 














	 	•	 	 Each Eligible Holder shall have the right, but not the obligation, to participate in the Rights Offering and
subscribe for the aggregate Subscription Price (as defined below) for its Rights Offering Securities (such right, the “Subscription Rights”); provided that (i) the Joining Legacy Parties2 (in their capacities as Eligible Holders) must also subscribe for their pro rata shares of the Holdback Securities, and shall be required to pay their respective aggregate Subscription Price
for such Holdback Securities on the Joining Legacy Party Funding Date (as defined below);3 and (ii) pursuant to and in accordance with the Backstop Commitment Agreement, the Backstop Parties4 (in their capacities as Eligible Holders) must exercise all of their Subscription Rights in full, including with respect to their allocations of Holdback Securities, at or prior to the Rights
Offering Expiration Time but shall not be required to pay their respective aggregate Subscription Price for any securities for which they subscribe until the Backstop Escrow Funding Date (as defined in the Backstop Commitment Agreement).5 If you exercise your Subscription Rights, you will have to PAY for such exercise at the Subscription Price, as described further below, and if you are a holder of Priority Guaranteed
Notes or Legacy Notes (together, the “Notes,” and the Priority Guaranteed Notes Claims and Legacy Notes Claims, together, the “Notes Claims”), arrange for the underlying Notes to be tendered in accordance with the
procedures described further below. 


  

	 	•	 	 Holders of Eligible Claims are not required to exercise any of their Subscription Rights (unless
they are party to the Backstop Commitment Agreement), but they may if they wish to do so and they follow the required procedures. 


  

	 	•	 	 Additional information regarding the Rights Offering is provided in this document and in the Subscription Forms
enclosed herewith. Eligible Holders should carefully review this document and the Subscription Forms in their entirety. 


  

 
  

	2 	 “Joining Legacy Parties” are Eligible Holders that participated in the Backstop Joinder Process (as
defined below) and have committed to subscribe for their allocation of Holdback Securities. Certain provisions of the Rights Offering Procedures are separately applicable to these parties. 



	3 	 Joining Legacy Parties that are exercising Subscription Rights with respect to Notes Claims must arrange for a
Restricted Access Addendum (as defined below) to be delivered to their Nominee (as defined below), who will provide the relevant Restricted Access Code (included in the Restricted Access Addendum) to the Subscription Agent (as defined below) when
tendering the underlying Notes through ATOP into the Restricted Access Group (as defined in the Restricted Access Addendum). 



	4 	 “Backstop Parties” are the parties to the Backstop Commitment Agreement who have committed to
subscribe for Rights Offering Securities that are not subscribed for in the Rights Offering. Certain provisions of the Rights Offering Procedures are separately applicable to these parties. 



	5 	 Backstop Parties that are exercising Subscription Rights with respect to Notes Claims must arrange for a
Restricted Access Addendum to be delivered 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.

The Rights Offering Securities distributed and issued pursuant to these Rights Offering Procedures are
being issued and distributed by the Company pursuant to the Rights Offering without registration under the Securities Act, in reliance upon the exemption from registration provided by Section 1145 of the Bankruptcy Code to the maximum extent
possible and, to the extent such exemption is unavailable, are 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. 
 None of the Subscription Rights or the Rights Offering Securities issuable upon
exercise of such Subscription Rights distributed pursuant to these Rights Offering Procedures have been or will be registered under the Securities Act, nor any state or local law requiring registration for offer and sale of a security. 

Except as provided in the Restructuring Support Agreement or the Backstop Commitment Agreement, the Subscription Rights
are not detachable from the Non-Notes Claims (as defined below) and may not be sold, transferred, assigned, pledged, hypothecated, participated, donated or otherwise encumbered or disposed of, directly or
indirectly (each, a “Transfer” and “Transfer” as a verb shall have a correlative meaning) separately from the Non-Notes Claims (including through derivatives, options, swaps,
forward sales or other transactions in which any person receives the right to own or acquire any current or future interest in the Subscription Rights). Furthermore, the Subscription Rights may only be exercised by Holders of Non-Notes Claims as of the Record Date. Accordingly, if an Eligible Holder sells or transfers its Non-Notes Claims after the Record Date, the purchaser or transferee will not
be eligible to receive or exercise Subscription Rights in respect of such Non-Notes Claims. 

The Subscription Rights corresponding to the Notes Claims will trade together with the underlying Eligible Claims and be
evidenced by the underlying Eligible Claims, until the Rights Offering Expiration Time, subject to such limitations, if any, that would be applicable to the transferability of the underlying Notes. 

The exercise of the Subscription Rights once made cannot be revoked after the Rights Offering Expiration Time unless the
Rights Offering is terminated. No transfer of the Eligible Claims corresponding to Subscription Rights that have been exercised will be recognized, unless the Rights Offering has been terminated. Notes that have been tendered cannot be withdrawn,
and therefore cannot be transferred, unless the Rights Offering has been terminated. 
 The
Disclosure Statement (as defined below) is being distributed in connection with the Debtors’ solicitation of votes to accept or reject the Plan and sets forth important information, including risk factors, that should be carefully read and
considered by each Eligible Holder prior to making a decision to participate in the Rights Offering. An electronic copy of the Disclosure Statement is available on the Debtors’ restructuring website at https://dm.epiq11.com/noble.

The Rights Offering is being conducted by the Debtors in good faith and in compliance with the Bankruptcy
Code. In accordance with section 1125(e) of the Bankruptcy Code, a debtor or any of its agents that participate, in good faith and in compliance with the applicable provisions of the Bankruptcy Code, in the offer, issuance, sale, or purchase of a
security offered or sold under the plan of the debtor, or an affiliate participating in a joint plan with the debtor, or of a newly organized successor to the debtor under the plan, is not liable, on account of such participation, for violation of
any applicable law, rule, or regulation governing the offer, issuance, sale or purchase of securities. 
 The
distribution or communication of these Rights Offering Procedures and the issuance of the Rights Offering Securities in certain jurisdictions may be restricted by Law. No action has been taken or will be taken to permit the distribution or
communication of these Rights Offering Procedures in any jurisdiction where any action for that purpose may be required. Accordingly, these Rights Offering Procedures may not be distributed or communicated, and the Rights Offering Securities may not
be subscribed for or issued, in any jurisdiction except in circumstances where such distribution, communication, subscription or issuance would comply with all applicable Laws without the need for the Issuers to take any action or obtain any
consent, approval or authorization therefor except for any notice filings required under U.S. federal and applicable state securities Laws. Further, the Company’s securities have not been approved or disapproved by the U.S. Securities and
Exchange Commission or any other state securities commission or any other regulatory or governmental authority, nor have any of the foregoing passed upon the accuracy or adequacy of the information presented, and any representation to the contrary
is a criminal offense. 
 To the extent any New Shares are issued to an Eligible Holder pursuant to the Rights
Offering in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act or another available exemption, each certificate evidencing such New 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 New Shares are issued to an Eligible Holder pursuant to the Rights
Offering in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act or another available exemption, such New 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. 


  
 4 












 
To the extent any Second Lien Notes are issued to an Eligible Holder pursuant to the Rights Offering in
reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act or another available exemption, each certificate evidencing such Second Lien 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. 
 To the extent any uncertificated Second Lien Notes are issued to
an Eligible Holder pursuant to the Rights Offering in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act or another available exemption, such Second Lien 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. 

In any member state of the European Economic Area (the “EEA”) or the United Kingdom
(each, a “Relevant State”), these Rights Offering Procedures are only addressed to and only directed at qualified investors in that Relevant State within the meaning of the Regulation (EU 2017/1129 (as retained pursuant to the
European Union (Withdrawal) Act 2018 in the United Kingdom) (the “Prospectus Regulation”). Qualified investors (as defined in the Prospectus Regulation) in the EEA shall be referred to as “Permitted EU Persons.”
These Rights Offering Procedures have been prepared on the basis that all offers to the public of Rights Offering Securities within a Relevant State will be made pursuant to an exemption under the Prospectus Regulation from the requirement to
publish a prospectus for offer of securities. Accordingly, any person making or intending to make any subscription for Rights Offering Securities within any Relevant State should only do so in circumstances in which no obligation arises to publish a
prospectus or a supplement to a prospectus under the Prospectus Regulation for such offer to the public. In relation to each Relevant State, no offer of the Rights Offering Securities or the Subscription Rights may be made to the public at any time
other than pursuant to an exemption under the Prospectus Regulation. None of Noble Corporation plc, its affiliates or any persons acting on their behalves has authorized, nor do they authorize, the making of any offer of Rights Offering Securities
through any financial intermediary, other than as may be contemplated herein. For the purposes of this provision, the expression an “offer to the public” in relation to any Rights Offering Securities in any Relevant State means the
communication in any form and by any means of sufficient information on the terms of the offer and any Rights Offering Securities to be offered so as to enable an investor to decide to purchase or subscribe for any Rights Offering Securities.

These Rights Offering Procedures have not been approved by an authorized person for the purposes of
section 21 of the United Kingdom’s Financial Services and Markets Act 2000 (as amended) (the “FSMA”). In the United Kingdom, distribution of these Rights Offering Procedures is exempt from the restriction in Section 21 of
the FSMA on the basis of Article 43 of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “FPO”). Accordingly, the Rights Offering Procedures are not being distributed to, and must not be
passed on to, the general public in the United Kingdom. In the United Kingdom, these Rights Offering Procedures are being distributed only to, and any offer or invitation contained in these Rights Offering Procedures is directed only at, persons who
are qualified investors (as defined in the Prospectus Regulation) and who are (i) investment professionals within the meaning of Article 19(5) of the FPO and/or (ii) high net worth companies (or persons to whom it may otherwise be lawfully
communicated) falling within Article 49(2)(a) to (d) of the FPO (all such persons together being referred to as “relevant persons” or “Permitted UK Persons”). Any person in the United Kingdom that is not a relevant
person should not act or rely on the information included in these Rights Offering Procedures or use it as the basis for taking any action. In the United Kingdom, any investment or investment activity that these Rights Offering Procedures relate to
may be made or taken exclusively by relevant persons.

 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”): 
  

	 	•	 	 Allowed General Unsecured Claims against Debtor Group B as of the Record Date; and 



 

	 	•	 	 Allowed General Unsecured Claims against Debtor Group C as of the Record Date; 



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: 
  

	 	•	 	 a “qualified institutional buyer” within the meaning of Rule 144A of the Securities Act;



  

	 	•	 	 an institution that is an “accredited investor” within the meaning of Rule 501(a) under the Securities
Act; or 


  

	 	•	 	 a non-U.S. person under Regulation S under the Securities Act that is
located outside of the United States; and, in each case, 


  

	 	•	 	 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.

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

	6 	 Pursuant to the terms of the Backstop Commitment Agreement, (i) the members of the Ad Hoc Guaranteed Group
shall subscribe for on the Effective Date, at an aggregate subscription price of $43,500,000, (x) $43,500,000 (less the aggregate nominal value of the Ad Hoc Guaranteed Group Holdback Shares (as defined below)) in aggregate principal amount of

immediately after the Effective Date (subject to dilution by the Warrants and the MIP)) (the “Ad Hoc Legacy Group Holdback Shares”, and together with the Ad Hoc Guaranteed Group Holdback Shares, the “Holdback
Shares”, and the Holdback Shares together with the Holdback Notes, the “Holdback Securities”).

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. 
  

	 	1.	 Rights Offering 



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. 
  

	 	2.	 Subscription Period 



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: 
  

	 	•	 	 if it is a Holder of Non-Notes Claims, its Subscription Form must be
received by the Rights Offering Subscription Agent; 


  

	 	•	 	 if it is a holder of Notes Claims, its Notes must be electronically tendered to the Rights Offering Subscription
Agent in accordance with DTC’s ATOP procedures by its Nominee; and 


  

	 	•	 	 if it is not a Backstop Party, the Subscription Price for its Rights Offering Securities must be received by the
Rights Offering Subscription Agent by wire transfer of immediately available funds. 


 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. 
  

	 	3.	 Delivery of Subscription Documents 



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. 

 

	 	4.	 Exercise of Subscription Rights 



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

 

	 	•	 	 if it is a holder of Non-Notes Claims, (a) duly complete and execute
a Subscription Form (including accompanying IRS Form W-9 or appropriate IRS Form W-8, as applicable) in accordance with these Rights Offering Procedures, and
(b) deliver its executed Subscription Form to the Rights Offering Subscription Agent such that the Subscription Form is received by the Rights Offering Subscription Agent at or prior to the Rights Offering Expiration Time;




  
 15 













	 	•	 	 if it is a holder of Notes Claims, (x) direct its Nominee to electronically tender its Notes to the
appropriate account of the Rights Offering Subscription Agent in accordance with DTC’s ATOP procedures at or prior to the Rights Offering Expiration Time, and (y) for any such holder that is a Backstop Party or Joining Legacy Party only,
deliver its Restricted Access Addendum to its Nominee, so that the Nominee 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; and 


  

	 	•	 	 as to the Subscription Price, 



 

	 	•	 	 if the Eligible Holder is a holder of Non-Notes Claims that is not a
Backstop Party, deliver payment of the Subscription Price at or prior to Rights Offering Expiration Time for the Rights Offering Securities for which it has subscribed by wire transfer ONLY of immediately available funds directly to
the Rights Offering Subscription Agent in accordance with the instructions included in the Subscription Form; and 


  

	 	•	 	 if the Eligible Holder is a holder of Notes Claims that is not a Backstop Party, coordinate payment of the
Subscription Price at or prior to the Rights Offering Expiration Time for the Rights Offering Securities for which it has subscribed by wire transfer ONLY of immediately available funds to the Rights Offering Subscription Agent; and



  

	 	•	 	 if the holder is a Backstop Party, make payment of the Subscription Price to the Backstop Escrow Account at or
prior to Backstop Escrow Funding Date in accordance with the Backstop Commitment Agreement; and 


  

	 	•	 	 if the holder is a Joining Legacy Party, in addition to and separately from any payment made with respect to such
holder’s Subscription Price for the Rights Offering Securities for which it has subscribed in the Rights Offering, make payment of the Subscription Price for such holder’s Holdback Securities to the account provided in the Joining Legacy
Party Funding Notice at or prior to Joining Legacy Party Funding Date in accordance with these Rights Offering Procedures. 



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. 
  


	 	5.	 Transfer Restriction; Revocation 



 

	 	(a)	 Except as provided in the Restructuring Support Agreement or the Backstop Commitment Agreement, the
Subscription Rights will not be detachable or transferable separately from the Eligible Claims. 


  

	 	(b)	 The Subscription Rights being exercised by Eligible Holders of
Non-Notes Claims may only be exercised by holders of such claims as of the Record Date. Accordingly, if an Eligible Holder sells or transfers its Non-Notes Claims after
the Record Date, the purchaser or transferee will not be eligible to receive or exercise Subscription Rights in respect of such Non-Notes Claims. 



 

	 	(c)	 Subject to the terms and conditions of the Restructuring Support Agreement or the Backstop Commitment
Agreement, the Subscription Rights corresponding to the Notes Claims will similarly trade together with the underlying Eligible Claims and be evidenced by the underlying Eligible Claims, until the Rights Offering Expiration Time, subject to such
limitations, if any, that would be applicable to the transferability of the underlying Notes. 


  

	 	(d)	 Once an Eligible Holder has properly exercised its Subscription Rights, subject to the terms and conditions
contained in these Rights Offering Procedures and the Backstop Commitment Agreement in the case of any Backstop Party, such exercise will be irrevocable unless the Rights Offering is terminated. Notes that have been tendered cannot be withdrawn, and
therefore cannot be transferred, unless the Rights Offering has been terminated. 


  

	 	6.	 Termination/Return of Payment 



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. 

 

	 	7.	 Settlement of the Rights Offering and Distribution of the Rights Offering Securities 



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). 
  

	 	8.	 Minimum Distributions and Fractional Shares 



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. 

 

	 	9.	 Validity of Exercise of Subscription Rights 



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. 

 

	 	10.	 Modification of Procedures 



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. 
  

	 	11.	 DTC 



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 













	 	12.	 Inquiries and Transmittal of Documents; Subscription Agent 



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. 

 

	 	13.	 Failure to Exercise Subscription Rights 



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.
