Article 2
The Securities

SECTION 2.01.Form and Dating. Provisions relating to the Securities are set forth in Appendix A attached hereto (“Appendix A”) which is hereby incorporated in, and expressly made part of,

this Indenture. The Securities and the Trustee’s certificate of authentication shall be substantially in the form included in Exhibit 1.1 to Appendix A, which are hereby incorporated in, and expressly made a part of, this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in Appendix A are part of the terms of this Indenture.

SECTION 2.02.Execution and Authentication. An Officer shall sign the Securities for the Company by manual or facsimile signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee, upon a written order of the Company signed by an Officer of the Company, together with the other documents required by Sections 14.02 and 14.03, shall authenticate Securities for original issue on the Issue Date in the aggregate principal amount not to exceed $1,175,000,000. Such written order of the Company shall specify the amount of Securities to be authenticated and the date on which the original issue of Securities is to be authenticated.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.03.Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate reasonable compensation therefor pursuant to Section 7.06. The Company may change the Paying Agent or Registrar without prior notice to the Holders. The Company or any of its Affiliates incorporated or organized within The United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Securities.

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Securities.

SECTION 2.04.Paying Agent To Hold Money in Trust. Prior to each due date of the principal of and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay

such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or any of its Affiliates acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.05.Lists of Holders of Securities. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Securities. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each interest payment date with respect to Securities and at such other times as the Trustee may reasonably request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Securities.

SECTION 2.06.Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to the Registrar or a co-registrar, if any, with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture (including Appendix A hereto) are met. When Securities are presented to the Registrar or a co-registrar, if any, with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary participants or beneficial owners of interests in any Definitive Security or Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Neither the Trustee nor any agent of the Trustee shall have any responsibility for any actions taken or not taken by the Depositary.

SECTION 2.07.Replacement Securities. If any mutilated Security is surrendered to the Trustee or either the Company or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Security, the Company shall issue and the Trustee, upon receipt of evidence of authentication in accordance with Section 2.02, shall authenticate a replacement Security if the Trustee’s requirements for replacement of Securities are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any agent and any authenticating agent from any loss that any of them may suffer if a Security is replaced. The Trustee and the Company each may charge such Holder for their expenses in replacing such Security.

Every replacement Security is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Securities duly issued hereunder.

SECTION 2.08.Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date, money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09.Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

SECTION 2.10.Cancellation . The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of in accordance with the Trustee’s policy then in effect (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation in accordance with its retention policy then in effect, unless the Company directs the Trustee in writing to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation.

SECTION 2.11.Defaulted Interest. If the Company defaults in a payment of principal, interest or any other amount on the Securities, the Company shall pay defaulted interest at the rate specified in the Securities (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the persons who are Holders of Securities on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon written request of the Company, the Trustee in the name and at the expense of the Company) will send to each Holder of Securities a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. The Trustee will have no duty whatsoever to determine whether any defaulted interest is payable or the amount thereof.

SECTION 2.12.CUSIP Numbers, ISINs, etc. The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

Article 3

SECTION 3.01.Notices to Trustee. If the Company elects to redeem Securities pursuant to Section 3.08 or Section 3.10, it shall notify the Trustee in writing of the redemption date, the principal

The Company shall give each notice to the Trustee provided for in this Section at least five Business Days prior to the giving of notice of a redemption unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officer’s Certificate from the Company to the effect that such redemption will comply with the conditions herein.

SECTION 3.02.Selection of Securities to Be Redeemed . Other than with respect to redemptions pursuant to Section 3.09(a), if fewer than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed (1) if such Securities are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which such Securities are listed, (2) if such Securities are not so listed but are in global form, then in accordance with the procedures of the Depositary or (3) if such Securities are not so listed and are not in global form, then on a pro rata basis, although no Security of $2,000 in original principal amount or less will be redeemed in part. Securities and portions of them the Trustee selects shall be in minimum principal amounts of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

SECTION 3.03.Notice of Redemption. At least 10 days but not more than 60 days before a date for redemption of Securities, the Company shall send, or cause to be sent (in the case of Securities held in book-entry form, by electronic transmission) a notice of redemption to each Holder of Securities to be redeemed at such Holder’s registered address or otherwise in accordance with the procedures of the Depositary. Notwithstanding the above, when notice has to be given to a holder of a Global Security (including any notice of redemption) such notice shall be sufficiently given if given to the Depositary (or its designee) pursuant to the standing instructions from the Depositary or its designee, including by electronic mail in accordance with Applicable Procedures. Notices to the Trustee may be given by email in PDF format. Any redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of an offering of shares, capital stock, other offering or other corporate transaction or event. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed. The Company shall provide written notice of the delay of such redemption date or the rescission of such notice of redemption (and rescission and cancellation of the redemption of the Securities) to the Trustee no later than 10:00 a.m. Eastern Time (subject to the Applicable Procedures) on the redemption date or the redemption date as so delayed.

(8)any conditions precedent to the redemption of the Securities; and

(9)that no representation is made as to the correctness or accuracy of the “CUSIP” number, ISIN, or “Common Code” number, if any, listed in such notice or printed on the Securities.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with an Officer’s Certificate delivered at least five Business Days prior to notification of the Holders (unless the Trustee consents to a shorter period) requesting that the Trustee give such notice of redemption and containing the information required by this Section.

SECTION 3.04.Effect of Notice of Redemption. Once notice of redemption is sent, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, unless the conditions described in the notice of redemption have not been satisfied. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date), and such Securities shall be canceled by the Trustee. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 3.05.Deposit of Redemption Price. On or prior to 11:00 a.m. Eastern time on the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or any of its Subsidiaries is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities or portions thereof to be redeemed on that date other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation.

(a)Without limiting any of the other covenants in this Article 4, each of the Existing Collateral Rig Issuers, the Collateral Rig Owners and the Collateral Rig Operators shall (i) conduct its business, and otherwise be, in compliance with all applicable laws, regulations, ordinances and orders of any governmental or judicial authorities; provided, however, that this Section 4.23 shall not require each of the Existing Collateral Rig Issuers, the Collateral Rig Owners or the Collateral Rig Operators to comply with any such law, regulation, ordinance or order if (x) it shall be contesting such law, regulation, ordinance or order in good faith by appropriate proceedings and reserves in conformity with GAAP have been provided therefor, or (y) the failure to comply therewith would not reasonably be expected to have a Material Adverse Effect, (ii) comply in all material respects with all obligations it might have under Anti-Corruption Laws, (iii) comply in all material respects with all applicable Sanctions, (iv) comply in all material respects with all laws and regulations applicable to the Collateral Rigs and the ownership, employment, operation, management and registration of the Collateral Rigs, including the applicable ISM Code, ISPS Code, Environmental Laws, and the laws of the applicable Flag Jurisdiction and (v) not employ the Collateral Rigs, nor allow their employment, operation or management, in any manner contrary in any material respect to any applicable law or regulation, including, but not limited to the applicable ISM Code, ISPS Code, Environmental Laws and Sanctions.

(d)In the event that a Drilling Contract is transferred to a Subsidiary of Holdings in accordance with Sections 4.13 and 4.26, as applicable, Holdings will cause the Subsidiary to which such Drilling Contract is transferred and any Subsidiary of Holdings which directly owns the Equity Interests of such Subsidiary (other than any Equity Interests of a Collateral Rig Operator owned by a Qualified Local Partner, if applicable at such time), to the extent not already an Equity Pledgor, to satisfy the Collateral and Guaranty Requirements with respect to such Drilling Contract and such Equity Interests of a Collateral Rig Operator and take such other actions in connection therewith as would otherwise have been required to be taken pursuant to this Indenture had such Subsidiary been a Collateral Rig Operator or an Equity Pledgor, as applicable, on the Issue Date (including the delivery of relevant opinions, officer certificates, resolutions and organizational documents) and deliver to the Collateral Agent an Officer’s Certificate confirming that the Collateral and Guaranty Requirements are satisfied and the Opinions of Counsel required as part of such Collateral and Guaranty Requirements.

Holdings shall cause each Collateral Rig Operator to continue to be a party to the Master Services Agreement and to have access to the Services (as defined therein) and personnel provided thereunder in order to comply with the performance standards under each Drilling Contract until the stated expiration date of such Drilling Contract regardless of whether the applicable Collateral Rig Owner or the Collateral Rig Operator remains an Affiliate of Holdings.

Each Collateral Rig Owner shall not transfer its Collateral Rig or its rights under the applicable Bareboat Charter to any other Person and Holdings shall not permit a Collateral Rig Operator to transfer its rights under an applicable Drilling Contract to any other Person, in each case, other than (i) to a Subsidiary of Holdings and (ii) subject to the satisfaction of the following conditions:

(a)such Subsidiary of Holdings has no Liens other than those permitted under the Indenture to be Incurred by a Collateral Rig Owner or a Collateral Rig Operator, as applicable;

SECTION 4.27.Post-Bankruptcy Restrictions. Holdings shall, and Holdings shall cause its Subsidiaries to, not take or support any of the following actions after the occurrence of an Event of Default under Section 6.01(f) or (g): (a) reject a Drilling Contract or a Bareboat Charter; or (b) challenge any transfer made in connection with the Note Documents as a preference or fraudulent conveyance.

SECTION 4.28.Waiver of Certain Covenants. Holdings may and may cause any Subsidiary of Holdings to omit in any particular instance to comply with any term, provision or condition set forth in the Indenture or any applicable Note Document (other than any term, provision or condition the amendment or waiver of which would require the consent of each Holder of an Outstanding Security affected thereby, pursuant to Section 10.02), if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities shall either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of Holdings and the Subsidiaries of Holdings and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive compliance with any covenant or condition hereunder. If a record date is fixed, the Holders of such record date, or their duly appointed agents, and only such Persons shall be entitled to waive any such compliance, whether or not such Holders remain Holders after such record date, provided that unless the Holders of at least a majority in aggregate principal amount of the Outstanding Securities shall have waived such compliance prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

The Company will not, in any transaction or series of transactions, consolidate with, merge with or into or complete a scheme of arrangement qualifying as an amalgamation with any Person, or sell, lease, convey, transfer or otherwise dispose of all or substantially all of its assets to any Person, unless:

SECTION 5.02.Successor Company Substituted. Upon any consolidation or merger of the Company, in which the Company is not the continuing entity, or any sale, lease, conveyance, transfer or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.01, the Successor formed by such consolidation or into or with which the Company is merged or to which such sale, lease, conveyance, transfer or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture and the Securities with the same effect as if such Successor had been named as the Company herein and the predecessor Company, in the case of a sale, conveyance, transfer or other disposition, shall be released from all obligations under this Indenture and the Securities, provided, that in the case of a lease of all or substantially all its assets, the predecessor Company will not be released from its obligations under this Indenture or the Securities.

Article 6

(a)failure to pay interest on any Security when such interest becomes due and payable and such default is continued for 30 days;

(b)failure to pay principal of (or premium including the Make-Whole Premium, if any, on) any Security when it becomes due and payable;

(c)failure by the Company to make an offer in connection with a Change of Control Repurchase Event or Event of Loss Repurchase Event in accordance with the provisions described under Section 4.02 of this Indenture;

(d)failure to comply with any covenant or agreement in this Indenture in respect of the Securities, and such default or breach is continued for 90 days (or 150 days with respect to Section 4.09 of this Indenture; provided, however, that beginning on the 91^st day the Note Parties are not in compliance with Section 4.09, additional interest at a rate of 0.25% per annum shall become due and payable (in the same manner and at the same time as regular interest payments) on the Securities until such covenant is complied with) after there has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal of Outstanding Securities affected thereby a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder (other than a default in performance, or breach, of a covenant or agreement specifically dealt with in clauses (a), (b) or (c) above);

(e)any Securities Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Securities Guarantee or pursuant to the terms of this Indenture or other

applicable Note Document) or any Guarantor denies or disaffirms its obligations under its Securities Guarantee;

(f)the Company or any other Note Party pursuant to or within the meaning of any Bankruptcy Law:

(1)commences a voluntary case,

(2)consents to the entry of an order for relief against it in an involuntary case,

(3)consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or

(4)makes a general assignment for the benefit of its creditors;

(g)a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for 90 days and that:

(1)is for relief against the Company or any other Note Party as debtor in an involuntary case,

(2)appoints a Bankruptcy Custodian of the Company or any other Note Party or a Bankruptcy Custodian for all or substantially all of the property of the Company, or any other Note Party or

(3)orders the liquidation of the Company or any other Note Party; or

(h)except as permitted by the Note Documents, the Security Documents shall for any reason cease to create a valid and perfected first-priority Lien (subject to Permitted Collateral Liens) on any portion of the Collateral having a fair market value in excess of $25,000,000 (in each case, other than in accordance with the terms of this Indenture or the terms of the Security Documents); provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 45 days after any Officer of any Collateral Grantor becomes aware of such failure, which failure has not been cured during such time period, or (ii) any Collateral Grantor asserts in writing that any Lien created under the Security Documents is invalid or unenforceable.

Upon the occurrence of an Event of Default pursuant to this Section 6.01 with respect to Securities all or part of which is represented by a Global Security, a record date shall automatically and without any other action taken by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in any Notice of Default, which record date shall be the close of business on the day the Trustee shall have received such Notice of Default. The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such Notice of Default, whether or not such Holders remain Holders after such record date; provided that, unless such Notice of Default shall have become effective by virtue of Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined in such Notice of Default prior to the day which is 90 days after such record date, such Notice of Default shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder (or duly appointed agent thereof) from giving, before or after expiration of such 90-day period, a Notice of Default contrary to or different from a Notice of Default previously given by a Holder, or from giving, after the expiration of such period, a Notice of Default identical to a Notice of Default that

has been cancelled pursuant to the proviso to the preceding sentence, in any of which events a record date in respect thereof shall be set pursuant to the provisions of this Section 6.01.

However, a Default under Section 6.01(d), (e) or (h) will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities (with a copy to the Trustee) notify the Company of the Default and, with respect to Section 6.01(d), (e) or (h), the Company does not cure such Default within the time specified in Section 6.01(d), (e) or (h) after receipt of such notice; provided that a notice of Default may not be given with respect to any action taken, and reported publicly or to the Holders, more than two years prior to such notice of Default.

SECTION 6.02.Acceleration of Maturity; Rescission and Annulment. If an Event of Default described in Section 6.01 (other than Event of Default specified in Section 6.01(f) or (g)) with respect to Securities at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount, if any, of the Outstanding Securities, declare the principal amount of all of the Securities and all interest thereon to be due and payable immediately, together with the Make-Whole Premium, if any, by a notice in writing to the Company (and to the Trustee if given by the Holders) and upon any such declaration such amounts shall become immediately due and payable. Upon the occurrence of an Event of Default specified in Section 6.01(f) or (g), the principal amount of all of the Securities, all interest thereon, and the Make-Whole Premium, if any, shall automatically and immediately become due and payable.

For the avoidance of doubt, if the principal amount of the Securities is paid on or prior to February 15, 2026 (other than pursuant to Section 3.08(b)-(d)), the Make-Whole Premium provided under Section 3.08 hereof shall be paid, even if such payment is made following acceleration pursuant to this Section 6.02. The Company will pay the Make-Whole Premium, as compensation to the Holders for the loss of their investment opportunity and not as a penalty, whether or not an Event of Default specified in Section 6.01(f) or (g) has occurred and (if an Event of Default specified in Section 6.01(f) or (g) has occurred) without regard to whether the event causing such Event of Default is voluntary or involuntary, or whether payment occurs pursuant to a motion, plan of reorganization, or otherwise, and without regard to whether the Securities and other Notes Obligations are satisfied or released by foreclosure (whether or not by power of judicial proceeding), deed in lieu of foreclosure or by any other means. Any premium payable pursuant to this Section 6.02 shall be presumed to be the liquidated damages sustained by each Holder as a result of the early repayment of the Securities and the Note Parties agree that it is reasonable under the circumstances currently existing. EACH NOTE PARTY EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE MAKE-WHOLE PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Company expressly agrees (to the fullest extent it may lawfully do so) that: (A) the Make-Whole Premium is reasonable and the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the Make-Whole Premium shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between Holders and the Company giving specific consideration in this transaction for such agreement to pay the Make-Whole Premium; and (D) the Company shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Company expressly acknowledges that its agreement to pay the Make-Whole Premium to the Trustee for the ratable benefit of the Holders as herein described is a material inducement to Holders to purchase the Securities.

At any time after such a declaration of acceleration with respect to Securities has been made, but before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1)the Company has paid or deposited with the Trustee a sum sufficient to pay in U.S. dollars,

(A)all overdue interest, if any, on all Outstanding Securities,

(B)all unpaid principal of (and premium including the Make-Whole Premium, if any, on) any Outstanding Securities which has become due otherwise than by such declaration of acceleration, and interest, if any, on such unpaid principal (and premium including the Make-Whole Premium, if any) at the rate or rates prescribed therefor in such Securities,

(C)to the extent that payment of such interest is lawful, interest on overdue interest, if any, at the rate or rates prescribed therefor in such Securities, and

(D)all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2)all Events of Default with respect to Securities other than the non-payment of amounts of principal of (or premium including the Make-Whole Premium, if any, on) or interest on Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Upon the Trustee providing any declaration of acceleration, or rescission and annulment thereof pursuant to this Section 6.02 with respect to Securities all or part of which is represented by a Global Security, a record date shall automatically and without any other action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join such declaration of acceleration, or rescission and annulment, as the case may be, which record date shall be the close of business on the date the Trustee shall have provided such declaration of acceleration, or rescission and annulment, as the case may be. The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such declaration of acceleration, or rescission and annulment, as the case may be, whether or not such Holders remain Holders after such record date; provided that, unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having been obtained prior to the day which is 90 days after such record date (or their duly appointed agents), such declaration of acceleration, or rescission and annulment, as the case may by, shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder (or duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a declaration of acceleration, or a rescission and annulment of any such declaration, contrary to or different from a declaration previously given by a Holder, or from giving, after the expiration of such period, a declaration identical to a declaration of acceleration, or rescission and annulment thereof, as the case may be, that has been cancelled pursuant to the proviso to the preceding sentence, in any of which events a new record date shall be established pursuant to the provisions of this Section 6.02.

SECTION 6.03.Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if:

(1)default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(2)default is made in the payment of the principal of (or premium including the Make-Whole Premium, if any, on) any Security at the Maturity thereof and on any date required under Section 3.09,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium including the Make-Whole Premium, if any) and interest, if any, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium including the Make-Whole Premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name, as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 6.04.Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium including the Make-Whole Premium, if any, or interest, if any) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1)to file and prove a claim for the whole amount of principal (and premium including the Make-Whole Premium, if any) and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(2)to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payment to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.05.Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 6.06.Application of Money Collected. Any money collected by the Trustee or the Collateral Agent pursuant to this Article (including upon any realization of any Lien upon Collateral) shall, subject to the terms of the Security Documents, be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium including the Make-Whole Premium, if any) or interest, if any, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee or the Collateral Agent and their agents and attorneys under Section 7.06;

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium including the Make-Whole Premium, if any) and interest, if any, on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium including the Make-Whole Premium, if any) and interest, if any, respectively; and

THIRD: The balance, to the Person or Persons entitled thereto.

SECTION 6.07.Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the Securities, or the other Note Documents, or for the appointment of a receiver or trustee, or for any other remedy hereunder or thereunder, unless:

(1)such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities;

(2)the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3)such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be Incurred in compliance with such request;

(4)the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5)no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing themselves of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a Holder affects, disturbs or prejudices the rights of other Holders or obtains or seeks to obtain priority or preference over such other Holders or enforces any right under this Indenture).

SECTION 6.08.Unconditional Contractual Right of Holders to Receive Principal, Premium and Interest. Subject to the following sentence, notwithstanding any other provision in this Indenture, the Holder of any Security shall have the contractual right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article 8) and in such Security of the principal of (and premium including the Make-Whole Premium, if any) and interest, if any, on such Security on the Stated Maturity or any Maturities (or, in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such contractual rights shall not be impaired without the consent of such Holder. Notwithstanding the foregoing, no amendment to, or deletion or waiver of any of the covenants described in Article 4 of this Indenture (other than Section 4.01) or in any other Note Document or any action taken by the Company or Guarantors not prohibited hereunder (other than with respect to actions set forth in the first paragraph of Section 10.02) shall be deemed to impair or affect any rights of any Holder to receive payment of principal of, and premium, interest and Additional Amounts, if any, on, the Securities.

SECTION 6.09.Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 6.10.Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 6.11.Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 6.12.Control by Holders. The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities in respect of which an Event of Default has occurred shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Outstanding

Securities, provided that in each case (1) such direction shall not be in conflict with any rule of law or with this Indenture, and (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Upon receipt by the Trustee of any such direction with respect to Securities all or part of which is represented by a Global Security, a record date shall automatically and without any further action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in such direction, which record date shall be the close of business on the day the Trustee shall have received such direction. The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such direction, whether or not such Holders remain Holders after such record date; provided that, unless such direction shall have become effective by virtue of Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such direction shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder (or a duly appointed agent of a Holder) from giving, before or after the expiration of such 90-day period, a direction contrary to or different from a direction previously given by a Holder, or from giving, after the expiration of such period, a direction identical to a direction that has been cancelled pursuant to the proviso to the preceding sentence, in any of which events a new record date in respect thereof shall be set pursuant to the provisions of this Section 6.12.

SECTION 6.13.Waiver of Past Defaults. Subject to Section 6.02, the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities may on behalf of the Holders of all the Outstanding Securities waive any past Default or Event of Default hereunder, except a default

(1)in the payment of the principal of (or premium including the Make-Whole Premium, if any) or interest on any Security or the payment of Additional Amounts, if any, or

(2)in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive any past Default or Event of Default hereunder. If a record date is fixed, the Holders on such record date (or their duly designated agents), and only such Persons, shall be entitled to waive any such default hereunder, whether or not such Holders remain Holders after such record date; provided, that unless such majority in principal amount shall have been obtained prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture and the other Note Documents; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

SECTION 6.14.Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit

instituted by any Holder or group of Holders holding in the aggregate more than 25% in aggregate principal amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium including the Make-Whole Premium, if any) or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the redemption date).

SECTION 6.15.Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted; provided that this Section shall not prohibit the Company from exercising any rights it may have under this Indenture to contest any actions taken by the Trustee pursuant to this Section.

SECTION 7.03.Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

SECTION 7.04.Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture (or any supplement thereto), the Securities or any of the Note Documents, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture, any Note Document or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

SECTION 7.05.Notice of Defaults . If a Default occurs with respect to the Securities and is continuing and written notice of such Default has been received by the Trustee as specified in Section 7.02(j), the Trustee shall send to each Holder a notice of the Default within 30 days after such written notice of it is received by a Trust Officer of the Trustee.

Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee with respect to the Securities by providing 31 days prior notice to the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

(1)the Trustee fails to comply with Section 7.09;

(2)the Trustee is adjudged bankrupt or insolvent;

(3)a receiver or other public officer takes charge of the Trustee or its property; or

(4)the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Company, or is removed by the Holders of a majority in principal amount of the Securities and the Company does not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Holders of a majority in principal amount of the Securities shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Securities. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company’s expense) or the Holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.09, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

SECTION 7.08.Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another Person, the resulting, surviving or transferee Person without any further act shall be the successor Trustee.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Securities so authenticated as if such successor to the Trustee had itself authenticated such Securities; and, in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificate shall have the full force as provided in the Securities or in this Indenture as the certificate of the trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Securities in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 7.09.Corporate Trustee Required; Eligibility. (a) There shall at all times be a Trustee hereunder which shall be:

(1)a corporation organized and doing business under the laws of the United States, or of any state or territory thereof, or of the District of Columbia, authorized under such laws to exercise corporate trust powers, and subject to supervision or examination by federal or state authority, or

(2)a corporation or other person organized and doing business under the laws of a foreign government permitted to act as a Trustee pursuant to a rule, regulation or other order of the Commission, authorized under such laws to exercise corporate trust powers, and subject to supervision or examination by authority of such foreign government or a political subdivision thereof substantially equivalent to supervision or examination applicable to United States institutional trustees.

(b)The Trustee shall have at all times a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.

SECTION 7.10.Debt Service Reserve Account. (a) The Trustee agrees to open and maintain (other than with respect to funding) the Debt Service Reserve Account at all times. All amounts contained in the Debt Service Reserve Account are to be held in trust by the Trustee for the benefit of the Secured Creditors.

(b)All of the funds deposited in the Debt Service Reserve Account shall be invested by the Trustee in the Truist Institutional Advantage Deposit Option 2.0, unless the Company instructs the Trustee in writing otherwise. All income or other gain from investment of funds deposited in the Debt Service Reserve Account shall be deposited by the Trustee in the Debt Service Reserve Account, and any loss resulting from such investments shall be charged to the Debt Service Reserve Account. In no event shall the Trustee or the Collateral Agent be liable for investment losses incurred with respect to funds deposited in the Debt Service Reserve Account.

(c)At any time that (i) the amount on deposit in the Debt Service Reserve Account exceeds the required Debt Service Reserve, (ii) the Aggregate Collateral Rig Leverage Ratio as of the date of the most recent quarterly compliance certificate delivered by the Company pursuant to Section 4.09(b) is less than or equal to the Rig Leverage Threshold (and remains less than or equal to the Rig Leverage Threshold after giving effect to the withdrawal described in this Section 7.10(c)) and (iii) no Default or Event of Default exists, the Company may withdraw the amount of such excess by executing and delivering a Withdrawal Certificate; provided that, the Company shall not make more than two such withdrawals in any calendar year.

SECTION 8.06.Reinstatement. If the Trustee or any paying agent is unable to apply any money in accordance with Section 8.05 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture, the Note Documents and such Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.05; provided, however, that if the Company makes any payment of principal of (or premium including the Make-Whole Premium, if any) or interest, if any, on any such Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or paying agent.

Article 11
Guarantees

SECTION 11.01.Guarantees. (i) Holdings, on a senior unsecured basis (the “Holdings Guarantee”), hereby fully and unconditionally guarantees, to each Holder and to the Trustee and its successors and assignees (x) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture with respect to the Securities and (y) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture with respect to the Securities and (ii) each Limited Guarantor in a Collateral Rig Guarantor Family, on a senior secured basis, hereby severally in respect of each other Collateral Rig Guarantor Family (but jointly and severally among the entities within such Collateral Rig Guarantor Family) guarantees up to the applicable Secured Limited Guarantee Cap outstanding immediately prior to the refinancing of the Existing Secured Notes (the “Secured Limited Guarantees,” and together with Holdings Guarantee, the “Guaranteed Obligations”) (x) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture with respect to the Securities and (y) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture with respect to the Securities, in each case subject to the Secured Limited Guarantee Cap. Each Guarantor of Securities further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor and that such Guarantor will remain bound under this Article 11 notwithstanding any extension or renewal of any obligation.

Each Guarantor of Securities waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor of Securities waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder of Securities shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Guarantor) under this Indenture with respect to the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture with respect to the Securities or any other agreement; (4) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 11.06, any change in the ownership of such Guarantor.

Each Guarantor of Securities further agrees that its Securities Guarantee herein constitutes a guarantee of payment (subject to the Secured Limited Guarantee Cap, if applicable), performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any Security held for payment of the Guaranteed Obligations.

Except as expressly set forth in Sections 9.01, 11.02 and 11.06 and subject to the Secured Limited Guarantee Cap, if applicable, the obligations of each Guarantor of Securities hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor of Securities herein shall not be discharged or impaired or otherwise affected by the failure

of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture with respect to the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor of Securities further agrees that its Securities Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder of Securities or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

Each Guarantor of Securities agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Guarantor’s Securities Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 11.01.

Each Guarantor of Securities also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 11.01.

SECTION 11.02.Limitation on Liability. (a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor of Securities shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

(b) Switzerland.

Notwithstanding anything to the contrary in this Indenture, the obligations of a Note Party incorporated and organized under the laws of Switzerland (each a “Swiss Guarantor”) and the rights of the Trustee, Collateral Agent and each Holder under this Indenture or any other Note Document are subject to the following limitations:

(1)

If and to the extent (i) a guarantee or security granted, indemnity or other obligation assumed by a Swiss Guarantor under this Indenture or any other Note Document guarantees or secures obligations of any of its (direct or indirect) Parent Companies (upstream

security) or sister companies (cross-stream security) (the “Upstream or Cross-Stream Secured Obligations”) and (ii) using the proceeds from the enforcement of such guarantee, security, indemnity or other obligation to discharge the Upstream or Cross-Stream Secured Obligations would be unlawful under Swiss mandatory law (inter alia, by constituting a repayment of capital (Einlagerückgewähr/Kapitalrückzahlung), a violation of the legally protected reserves (gesetzlich geschützte Reserven) or the payment of a (constructive) dividend (Gewinnausschüttung)) at such time, the proceeds from the enforcement of such guarantee, security, indemnity or other obligation to be used to discharge the Upstream or Cross-Stream Secured Obligations shall be limited to the maximum amount of such Swiss Guarantor’s freely disposable equity at the time of enforcement (the “Maximum Amount”); provided that such limitation is required under the applicable Swiss mandatory law at that time; provided, further, that such limitation shall not free such Swiss Guarantor from its obligations, or prevent the Trustee or Collateral Agent from applying such enforcement proceeds, in excess of the Maximum Amount, but merely postpone the performance date of those obligations until such time or times as performance is again permitted under then applicable Swiss mandatory law. This Maximum Amount of freely disposable equity shall be determined in accordance with Swiss law and applicable Swiss accounting principles and, if and to the extent required by applicable Swiss law, shall be confirmed by the auditors of such Swiss Guarantor on the basis of an interim audited balance sheet as of that time.

(2)

In respect of Upstream or Cross-Stream Secured Obligations, each Swiss Guarantor shall, as concerns the proceeds resulting from the enforcement of any guarantee or security granted or indemnity or other obligation assumed by such Swiss Guarantor under this Indenture or any other Note Document, if and to the extent Swiss Withholding Tax is required by applicable law in force at the relevant time to be paid in relation thereto:

(a)

procure that such payment or enforcement proceeds can be used to discharge Upstream or Cross-Stream Secured Obligations without deduction of Swiss Withholding Tax by discharging the liability to pay such tax by notification pursuant to applicable law (including double tax treaties) rather than payment of the tax;

(b)

if the notification procedure pursuant to sub-paragraph (i) above:

(i)applies for a part of the Swiss Withholding Tax only, such Swiss Guarantor undertakes to deduct (and, with respect to enforcement proceeds of security, the Collateral Agent, acting at the direction of the requisite Holders, undertakes to deduct) from any payment or enforcement proceeds used to discharge Upstream or Cross-Stream Secured Obligations an amount of Swiss Withholding Tax at the reduced rate resulting after the discharge of part of such tax by notification under applicable law; or

(ii)does not apply, deduct (and, with respect to enforcement proceeds of security, the Collateral Agent, acting at the direction of the requisite Holders, undertakes to deduct) an amount equivalent to the Swiss Withholding Tax at such rate (currently 35% at the date of this Indenture) as is in force from time to time from any such payment or enforcement proceeds used to discharge Upstream or Cross-Stream Secured Obligations that may be due by such Swiss Guarantor to the Swiss Federal

Tax Administration from such payment or enforcement, and, in the case of each of the foregoing clauses (i) and (ii), subject to any applicable double taxation treaty or any other applicable treaty, pay (and, with respect to enforcement proceeds of security, the Collateral Agent, acting at the direction of the requisite Holders, undertakes to pay), without delay, any such taxes deducted to the Swiss Federal Tax Administration in the name and for the account of the Swiss Guarantor;

(c)

notify the Trustee or Collateral Agent, as applicable, that such notification or, as the case may be, deduction has been made, and provide the Trustee or Collateral Agent, as applicable, with evidence that such a notification of the Swiss Federal Tax Administration has been made or, as the case may be, such taxes deducted have been paid to the Swiss Federal Tax Administration; and

(d)

in the case of a deduction of Swiss Withholding Tax,

(i)use its best efforts to ensure that any person, which is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment or enforcement proceeds, will, as soon as possible after such deduction (A) request a refund of Swiss Withholding Tax under applicable law (including tax treaties); and (B) pay to the Trustee or Collateral Agent, as applicable, upon receipt any amount so refunded; and

(ii) if the Trustee, the Collateral Agent or any Holder is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment or enforcement proceeds, and if requested by the Trustee, the Collateral Agent or any such Holder, shall provide to the Trustee, the Collateral Agent or any such Holder those documents that are required by law and applicable tax treaties to be provided by the payer of such tax to prepare a claim for refund of Swiss Withholding Tax.

(3)

If a Swiss Guarantor or the Collateral Agent is obliged to deduct Swiss Withholding Tax in accordance with paragraph (2) above, the Trustee, the Collateral Agent and each Holder shall be entitled to further enforce the guarantee or security granted or indemnity or other obligation assumed by such Swiss Guarantor under this Indenture or any other Note Document and/or further apply proceeds therefrom against Upstream or Cross-Stream Secured Obligations up to an amount which is equal to that amount which would have been obtained if no withholding of Swiss Withholding Tax were required, whereby such further enforcements/applications of proceeds shall always be limited to the Maximum Amount as set out in paragraph (1) above.

(4)

If and to the extent (i) reasonably requested by the Trustee or Collateral Agent, as applicable, or (ii) required under Swiss mandatory law applicable at the relevant time, in order to allow the Trustee and Collateral Agent, as applicable, and each Holder to obtain a maximum benefit under the guarantee or security granted or indemnity or other obligation assumed by such Swiss Guarantor, such Swiss Guarantor shall, and any Parent Company of such Swiss Guarantor being a party to this Indenture or any other Note Document shall procure that such Swiss Guarantor will, promptly take and promptly cause to be taken any action, including the following:

(a)

the passing of any shareholders' resolutions to approve the payment or use of the enforcement proceeds, which may be required as a matter of Swiss mandatory law in force at the time of the enforcement of the Upstream or Cross-Stream Secured Obligations in order to allow a prompt use of the enforcement proceeds;

(b)

preparation of an up-to-date audited balance sheet of such Swiss Guarantor;

(c)

confirmation of the auditors of that Swiss Guarantor that the relevant amount represents the Maximum Amount;

(d)

conversion of restricted reserves into profits and reserves freely available for the distribution as dividends (to the extent permitted by mandatory Swiss law);

(e)

revaluation of hidden reserves (to the extent permitted by mandatory Swiss law);

(f)

to the extent permitted by applicable law and Swiss accounting standards, write-up or realize any of its assets that are shown in its balance sheet with a book value that is significantly lower than the market value of the assets, in case of realization, however, only if such assets are not necessary for the respective Swiss Guarantor’s business (nicht betriebsnotwendig); and

(g)

all such other measures necessary or useful to allow the Trustee, Collateral Agent, and each Holder to use enforcement proceeds as agreed hereunder with a minimum of limitations.

Notwithstanding anything to the contrary in this Indenture or any other Note Document, the obligations and liabilities of a guarantor incorporated and organized under the laws of Norway and the rights of the Trustee, Collateral Agent and each Holder under this Indenture or any other Note Document, shall be limited to the extent required by the mandatory provisions of the Norwegian Private Limited Companies Act 1997, including sections 8-10 and/or 8-7, regulating unlawful financial assistance and other restrictions on a Norwegian limited liability company's ability to grant guarantees, loans or security interests.

SECTION 11.03.Successors and Assigns. This Article 11 shall be binding upon each Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 11.04.No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise.

SECTION 11.05.Modification. No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any

Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 11.06.Release of Certain Guarantors. (a) A Guarantor will be automatically released from its obligations under this Article 11:

(1)as provided for in Section 4.13(f);

(2)upon defeasance or covenant defeasance of the Securities pursuant to Article 8 or if the Company’s obligations under this Indenture are satisfied and discharged pursuant to Article 9; or

(3)in the case of a Collateral Rig Owner, upon the replacement of such Collateral Rig Owner in connection with a transfer of the applicable Collateral Rig in accordance with Section 4.26 pursuant to which another Wholly-Owned Subsidiary of Holdings shall become a Collateral Rig Owner and a Guarantor hereunder.

(b)At the request of the Company and upon delivery of an Officer’s Certificate and Opinion of Counsel, if required, the Trustee shall execute and deliver an appropriate instrument evidencing the release of a Guarantor pursuant to this Section 11.06.

SECTION 12.03.Release Documentation. Upon compliance with the conditions to release of all or any portion of the Collateral set forth in Section 12.02, the Collateral Agent and the Trustee shall forthwith take all necessary action (at the request of and the expense of the Company, accompanied by an Officer’s Certificate and Opinion of Counsel that the conditions precedent to such release have been satisfied) to release and re-convey to the applicable Collateral Grantor the applicable portion of the Collateral that is authorized to be released pursuant to Section 12.02, and shall deliver such Collateral in its possession to the applicable Collateral Grantor, including, without limitation, executing and delivering releases and satisfactions wherever required.

SECTION 12.04.Possession and Use of Collateral; No Impairment of the Security Interests.

(a)So long as no Event of Default has occurred and is continuing, and subject to the terms of this Indenture and the Security Documents, each Collateral Grantor will be entitled to freely operate the property and assets constituting the Collateral pledged by it and to receive, invest and dispose of all cash dividends, principal, interest and other payments made upon or with respect to the Collateral pledged by it and to exercise any voting and other consensual rights pertaining to the Collateral pledged by it.

(b)No Collateral Grantor shall take any action, or knowingly omit to take any action, which action or omission would have the result of materially impairing the validity, perfection or priority of the security interests in the Collateral created by the Security Documents, (except as expressly set forth in this Indenture or the Security Documents, including any action that would result in a Permitted Collateral Lien).

(c)No Collateral Grantor shall take any action or otherwise attempt to enforce any claim or maritime lien held by it against a Collateral Rig that has priority over any claim or Lien of the Collateral Agent in respect of such Collateral Rig, including any claims or Liens arising under the applicable Collateral Rig Mortgage.

(d)The Collateral Agent will distribute all funds received by it in accordance with the provisions of the Security Documents, and the Trustee will distribute all funds received by it from the Collateral Agent for the benefit of the Trustee and the Holders in accordance with the provisions of this Indenture.

SECTION 12.05.Collateral Agent. The Trustee and each of the Holders by acceptance of the Securities hereby authorize the appointment of the Collateral Agent as the Trustee’s and the Holders’ Collateral Agent under the Security Documents and in its capacity as mortgagee and security trustee pursuant to the Collateral Rig Mortgages, and the Trustee and each of the Holders by acceptance of the Securities hereby irrevocably authorize the Collateral Agent to enter into the Security Documents and to take such action on their behalf under the provisions of the Security Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Security Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Security Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or fiduciary relationship with the Trustee, any Holder, the Company, any Collateral Grantor or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

The Trustee is authorized and directed by the Holders and the Holders by acquiring the Securities are deemed to have authorized the Trustee, as applicable, to cause the Collateral Agent to enter into and perform its obligations under the Security Documents. The Collateral Agent is authorized and directed by the Trustee and the Holders and the Holders by acquiring the Securities are deemed to have authorized the Collateral Agent, to (i) enter into the Security Documents to which it is a party, (ii) bind the Trustee and the Holders on the terms as set forth in such Security Documents and (iii) perform and observe its obligations and exercise its rights and powers under such Security Documents, including entering into amendments, supplements and other modifications permitted by the terms of this Indenture or the Security Documents. Each Holder, by its acceptance of a Security, is deemed to have consented and agreed to the terms of each Security Document, as originally in effect and as amended, restated, replaced, supplemented or modified from time to time in accordance with its terms or the terms of this Indenture. Each of the Holders by acquiring the Securities is hereby deemed to have directed the Trustee to appoint the Collateral Agent as its mortgagee and security trustee and, for purposes of Swiss law, as agent, to receive, hold, administer and enforce the Collateral Rig Mortgages covering the Collateral Rigs, as contemplated under this Indenture.

Without limiting the generality of the foregoing, in relation to Swiss law-governed Security Documents (the “Swiss Security Documents”), each present and future Holder, by its acceptance of a Security, is deemed to have consented and agreed that:

(a)the Collateral Agent holds: (A) any security created or evidenced or expressed to be created or evidenced under or pursuant to a Swiss Security Document by way of a security assignment (Sicherungsabtretung) or transfer for security purposes (Sicherungsübereignung) or any other non-accessory (nicht akzessorische) security and (B) any proceeds and other benefits of such security, as fiduciary (treuhänderisch) in its own name but for the account of all relevant Holders which have the benefit

of such security in accordance with this Indenture and the respective Swiss Security Document; and each present and future Holder hereby agrees that the Collateral Agent enters into any such Swiss Security Document as fiduciary (treuhänderisch) in its own name but for the account of all relevant Holders; and

(b)it authorizes the Collateral Agent: (A) to (a) accept and execute as its direct representative (direkter Stellvertreter) any Swiss law pledge or any other Swiss law accessory (akzessorische) security created or evidenced or expressed to be created or evidenced under or pursuant to a Swiss Security Document for the benefit of such Holder and (b) hold, administer and, if necessary, enforce any such security as direct representative (direkter Stellvertreter) on behalf of each relevant Holder which has the benefit of such security; (B) to agree as its direct representative (direkter Stellvertreter) to amendments and alterations to any Swiss Security Document which creates or evidences or expressed to create or evidence a pledge or any other Swiss law accessory (akzessorische) security; (C) to effect as its direct representative (direkter Stellvertreter) any release of a security created or evidenced or expressed to be created or evidenced under a Swiss Security Document in accordance with this Indenture and the respective Swiss Security Document; and (D) to exercise as its direct representative (direkter Stellvertreter) such other rights granted to the Collateral Agent under this Indenture and under the relevant Swiss Security Document.

The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee or unless a written notice of any event which is in fact such a Default is received by the Collateral Agent at the address specified in Section 14.01, and such notice references the Securities and this Indenture. The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 or the Holders of a majority in aggregate principal amount of the Securities (subject to this Section 12.05).

The Collateral Agent shall have no obligation and makes no representation whatsoever to the Trustee or any of the Holders as to the existence, genuineness, value or protection of the Collateral or the sufficiency of any Security Documents, or that the Collateral is owned by any of the Collateral Grantors or is cared for, protected or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Collateral Grantor’s property constituting Collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture or any other Security Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder as to any of the foregoing. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act. For the avoidance of doubt, nothing herein shall require the Collateral Agent to file financing statements or continuation statements, to record any documents or instruments in any public office at any time or be responsible for perfection or maintaining the perfection of the security interests purported to be created by the Security Documents and such responsibility shall be solely that of the Company.

Each of the Collateral Agent and the Trustee, each in its capacity as such, shall not be liable or responsible for the failure of the Company or any Collateral Grantor to maintain insurance on the Collateral, nor shall it be responsible for any loss due to the insufficiency of such insurance or by reason of the failure of any insurer to pay the full amount of any loss against which it may have insured to the Company or any Collateral Grantor, the Trustee, the Collateral Agent or any other Person. The provisions of Article 7, mutatis mutandis, shall apply to the Collateral Agent.

The Trustee is authorized and directed by the Holders and the Holders by acquiring the Securities are deemed to have authorized the Trustee, as applicable, to cause the Collateral Agent to enter into and perform its obligations each Deed of Quiet Enjoyment. The Collateral Agent is authorized and directed by the Trustee and the Holders and the Holders by acquiring the Securities are deemed to have authorized the Collateral Agent, to (i) enter into each Deed of Quiet Enjoyment to which it is a party, (ii) bind the Trustee and the Holders on the terms as set forth in each such Deed of Quiet Enjoyment and (iii) perform and observe its obligations and exercise its rights and powers under each such Deed of Quiet Enjoyment, including entering into amendments, supplements and other modifications permitted by the terms of this Indenture or the applicable Deed of Quiet Enjoyment. Each Holder, by its acceptance of a Security, is deemed to have consented and agreed to the terms of each Deed of Quiet Enjoyment, as originally in effect and as amended, restated, replaced, supplemented or modified from time to time in accordance with its terms or the terms of this Indenture.

SECTION 12.06.Replacement of Collateral Agent. The Collateral Agent may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove Collateral Agent with respect to the Securities by providing 31 days prior notice to the Collateral Agent and may appoint a successor Collateral Agent. The Company shall remove Collateral Agent if:

(1)the Collateral Agent is adjudged bankrupt or insolvent;

(2)a receiver or other public officer takes charge of the Collateral Agent or its property; or

(3)the Collateral Agent otherwise becomes incapable of acting.

If the Collateral Agent resigns or is removed by the Company, or is removed by the Holders of a majority in principal amount of the Securities and the Company does not reasonably promptly appoint a successor Collateral Agent, or if a vacancy exists in the office of Collateral Agent for any reason (the Collateral Agent in such event being referred to herein as the retiring Collateral Agent), the Holders of a majority in principal amount of the Securities shall promptly appoint a successor Collateral Agent.

A successor Collateral Agent shall deliver a written acceptance of its appointment to the retiring Collateral Agent and to the Company. Thereupon the resignation or removal of the retiring Collateral Agent shall become effective, and the successor Collateral Agent shall have all the rights, powers and duties of the Collateral Agent under this Indenture. The successor Collateral Agent shall mail a notice of its succession to Holders of the Securities. The retiring Collateral Agent shall promptly transfer all property held by it as Collateral Agent to the successor Collateral Agent.

If a successor Collateral Agent does not take office within 30 days after the retiring Collateral Agent resigns or is removed, the retiring Collateral Agent (at the Company’s expense) or the Holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Collateral Agent.

SECTION 12.07.Purchaser Protected. No purchaser or grantee of any property or rights purporting to be released from the Liens in favor of the Collateral Agent shall be bound to ascertain the authority of the Collateral Agent or Trustee to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority so long as the conditions set forth in Section 12.02 have been satisfied.

SECTION 12.08.Authorization of Receipt of Funds by the Trustee Under the Security Documents. The Trustee is authorized to receive any funds for the benefit of Holders distributed under the Security Documents and to apply such funds as provided in Section 6.06.

SECTION 12.09.Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 12 upon any Collateral Grantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of any Collateral Grantor, as applicable, or of any officer or officers thereof required by the provisions of this Article 12.

SECTION 12.10.Compensation and Indemnification. The Collateral Agent shall be entitled to the compensation and indemnification set forth in Section 7.06 (with the references to the Trustee therein being deemed to refer to and include the Collateral Agent).

SECTION 12.11.Form of Security Documents and Opinions . To the extent that any provision of this Indenture or any Security Document requires the execution or delivery by the Trustee or the Collateral Agent after the Issue Date of any Security Documents, agreements, certificates, opinions or other documents (including, without limitation, any such opinions or documents described in the definition of “Collateral and Guaranty Requirements”), in each case, in form and substance reasonably satisfactory to the Trustee or the Collateral Agent, or other similar discretionary approval, or in substantially in the same form as such Security Documents, agreements, certificates, opinions or other documents were delivered on the Issue Date or as attached hereto, the Holders, by acquiring the Securities, are deemed to have approved the form and substance of any such Security Documents, agreements, certificates, opinions or other documents in substantially the same form as those executed and delivered on the Issue Date, in each case, with such changes as may be appropriate to reflect the entity subject to or the subject of or the governing law of such Security Documents, agreements, certificates, opinions or other documents and the jurisdiction of organization of such entity and hereby authorize the Trustee and the Collateral Agent, as applicable, to execute such documents and accept such documents and opinions. For the avoidance of doubt, this Section 12.11 shall not supersede any requirement contained herein regarding the delivery of an Officer’s Certificate or an Opinion of Counsel.

Article 13
Additional Amounts

SECTION 13.01.Payment of Additional Amounts.

(a)The Company shall pay any amounts due with respect to the Securities and the Guarantors will pay any amounts due with respect to the Securities Guarantees without deduction or withholding for any and all present and future withholding taxes, levies, imposts and charges (a “withholding tax”) imposed by or for the account of the Cayman Islands, Switzerland, any other jurisdiction in which either the Company or a Guarantor is a resident for tax purposes, any jurisdiction from or through which payment is made by or on behalf of the Company or any Guarantor (including, without limitation, the Paying Agent) or any political subdivision or taxing authority of any such jurisdiction (the “Taxing Jurisdiction”), unless such withholding or deduction is required by law. If such deduction or withholding is at any time required, the Company or such Guarantor, as applicable, will, to the fullest extent allowed by law (subject to compliance by the holder of a Security with any relevant administrative requirements), pay additional amounts (the “Additional Amounts”) in respect of principal amount, redemption price and interest (if any), in accordance with the terms of the Securities and this Indenture, as may be necessary so that the net amounts paid to the holder or the Trustee after such deduction or withholding will equal the

principal amount, redemption price and interest (if any), on the Securities. However, neither the Company nor any Guarantor will pay any Additional Amounts in the following instances:

(1)if any withholding would not be payable or due but for the fact that (i) the holder of a Security (or a fiduciary, settlor, beneficiary of, member or shareholder of, the holder, if the holder is an estate, trust, partnership or corporation), is a domiciliary, national or resident of, or engaging in business or maintaining a permanent establishment or being physically present in, the Taxing Jurisdiction or otherwise having some present or former connection with the Taxing Jurisdiction other than the holding or ownership of the Security or the collection of principal amount, redemption price, repurchase price and interest (if any), in accordance with the terms of the Securities and this Indenture, or the enforcement of the Security or (ii) where presentation is required, the Security was presented more than 30 days after the date such payment became due or was provided for, whichever is later;

(2)if any withholding tax is attributable to any estate, inheritance, gift, sales, transfer, excise, personal property or similar tax, levy, impost or charge;

(3)if any withholding tax is attributable to any tax, levy, impost or charge which is payable otherwise than by withholding from payment of principal amount, redemption price, repurchase price and interest (if any);

(4)if any withholding tax would not have been imposed but for the failure to comply with certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the relevant tax authority of the holder or beneficial owner of the Security, if (i) this compliance is required by statute or by regulation as a precondition to relief or exemption from such withholding tax, (ii) the holder (including any intermediary or other applicable person) or beneficial owner of the Security is legally eligible to comply with such certification, information, documentation or other reporting requirements, and (iii) at least 30 days prior to the first payment date with respect to which the Company or such Guarantor shall apply this clause (4) with respect to such withholding tax, the Company or such Guarantor shall have notified all Holders in writing that any holders (including any intermediary or other applicable person) or any beneficial owners of the Securities shall be required to provide such certification, information, documentation or other reporting requirements;

(5)to the extent a holder of a Security is entitled to a refund or credit in such Taxing Jurisdiction of amounts required to be withheld by such Taxing Jurisdiction;

(6)if any withholding is required to be made pursuant to laws enacted by Switzerland providing for the taxation of payments according to principles similar to those laid down in the draft legislation of the Swiss Federal Council of December 17, 2014, or otherwise changing the Swiss federal withholding tax system from an issuer-based system to a paying-agent-based system pursuant to which a person other than the issuer is required to withhold tax on any interest payments;

(7)if any withholding tax or deduction is required to be made in respect of any tax, duty, assessment or other governmental charge imposed or withheld pursuant to Sections 1471 through 1474 of the Code, as of the date hereof (or any amended or successor version), current or future U.S. Treasury Regulations issued thereunder or any official interpretation thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code; or

(8)any combination of the instances described in the preceding clauses.

(b)With respect to clause (a)(5) above, in the absence of evidence satisfactory to the Company or the applicable Guarantor, it may conclusively presume that a holder of a Security is entitled to a refund or credit of all amounts required to be withheld. The Company or the applicable Guarantor also will not pay any Additional Amounts to any holder who is a fiduciary or partnership or other than the sole beneficial owner of the Security to the extent that a beneficiary or settlor with respect to such fiduciary, or a member of such partnership or a beneficial owner thereof, would not have been entitled to the payment of such Additional Amounts had such beneficiary, settlor, member or beneficial owner been the holder of the Security.

(c)Whenever in this Indenture or the Securities there is mentioned, in any context, the payment of amounts based upon the principal amount of the Securities or of principal, interest or any other amount payable under, or with respect to, any of the Securities or any Security Guarantee, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof, after giving effect to Sections 13.01(a)(1) through (8).

SECTION 13.02.Swiss Minimum Interest.

(a)When entering into this Indenture, the parties have assumed that the payments under the Indenture and the other Note Documents are not and will not become subject to any tax deduction on account of Swiss Withholding Tax.

(b)Notwithstanding the paragraph above if a tax deduction on account of Swiss Withholding Tax should, at any time, be or become required by law in respect of any payment under the Indenture or any other Note Document and should it be unlawful for a Swiss Guarantor to comply with Section 13.01 for any reason (where this would otherwise be required by the terms of Section 13.01) then:

(1)the applicable interest rate in relation to that payment shall be the interest rate which would have applied to that payment, as provided for in the applicable Security, divided by 1 minus the rate at which the relevant tax deduction is required to be made under Swiss domestic tax law and/or applicable double taxation treaties (where the rate at which the relevant tax deduction is required to be made is for this purpose expressed as a fraction of 1); and

(2)such Swiss Guarantor shall:

(A)pay the relevant interest at the adjusted rate in accordance with paragraph (1) above;

(B)make a tax deduction on the interest so recalculated; and

(C)all references to a rate of interest under the Note Documents shall be construed accordingly.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of any Note Party may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion of, or representation by, counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of any Note Party stating that the information with respect to such factual matters is in the possession of such Note Party unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

TRANSOCEAN INC.

8.75% Senior Secured Notes due 2030

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

INTEREST. Transocean Inc. (the “Company”) promises to pay interest on the principal amount of this Security at 8.75% per annum. The Company shall pay interest semi-annually in arrears on February 15 and August 15 of each year, commencing August 15, 2023. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from January 31, 2023. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal, interest and other overdue amounts at a rate per annum equal to the rate which is 2.00% in excess of the rate which would have been payable if such overdue amount had, during the period of non-payment, constituted an outstanding amount of the Securities. Such interest shall be payable in accordance with Section 2.11 of the Indenture.

METHOD OF PAYMENT. The Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the February 1 and August 1 next preceding the interest payment date even if such Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company shall make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, shall be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

PAYING AGENT AND REGISTRAR. Initially, Truist Bank, a banking corporation organized and existing under the laws of the State of North Carolina (the “Trustee”), shall act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its Affiliates incorporated or organized within The United States of America may act as Paying Agent, Registrar or co-registrar.

INDENTURE. The Company issued the Securities under an Indenture dated as of January 31, 2023 (the “Indenture”), among the Company, the Guarantors, the Trustee and the Collateral Agent. This Security is one of a duly authorized issue of notes of the Company designated as its 8.75% Senior Secured Notes due 2030, initially issued in the aggregate principal amount of $1,175,000,000. The terms of the Securities include those stated in the Indenture, and Holders are referred to the Indenture for a statement of those terms (which for greater certainty includes the right of exchange of the Securities provided in Appendix A to the Indenture, which is an express term of this Security). To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

(c)Notwithstanding the foregoing, in connection with any tender offer for the Securities, including a Change of Control Offer or an Event of Loss Offer, if Holders of not less than 90% in aggregate principal amount of the Outstanding Securities validly tender and do not validly withdraw such Outstanding Securities in such tender offer and the Company, or any third party making such tender offer in lieu of the Company, purchases all of the Outstanding Securities validly tendered and not validly withdrawn by such Holders, the Company or such third party will have the right upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase date, to redeem all Securities that remain outstanding following such purchase at a redemption price equal to the price offered to each other Holder (excluding any early tender or incentive fee) in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the date of such redemption. In determining whether the Holders of at least 90% of the aggregate principal amount of the Outstanding Securities have validly tendered and not validly withdrawn such Securities in a tender offer, including a Change of Control Offer or an Event of Loss Offer, the Securities owned by the Company or its Affiliates or by funds controlled or managed by any Affiliate of the Company, or any successor thereof, shall be deemed to be outstanding for the purposes of such tender offer.

(d)Following any Event of Loss, the Company shall be entitled at its option to redeem an aggregate principal amount of Securities up to the Event of Loss Principal Amount at a redemption price equal to 100% of the principal amount of the Securities redeemed, plus accrued and unpaid interest thereon to, but not including, the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date); provided that any such notice of such redemption must be given on or prior to the 15th day after the full amount of the insurance proceeds in connection with such Event of Loss are received by any Note Party or other Subsidiary of Holdings; provided, further, that if Holdings or any Subsidiary thereof makes an Event of Loss Offer with respect to an Event of Loss, the Company shall be prohibited from redeeming Securities pursuant to Section 3.08(d) of the Indenture with respect to such Event of Loss, regardless of the amount of Securities tendered in such Event of Loss Offer.

6.	MANDATORY REDEMPTION. The Securities are subject to mandatory redemption as described in Section 3.09 of the Indenture.

Exhibit 1.1-5

REPURCHASE EVENTS. Upon the occurrence of a Change of Control Repurchase Event, unless the Company shall have exercised its option pursuant to Section 5 hereof to redeem the Securities, the Company will be required to make an offer to each Holder of the Securities, to repurchase all or any part (in denominations of a minimum principal amount of $2,000 and integral multiples of $1,000 in excess thereof) of that Holder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities to be repurchased plus any accrued and unpaid interest on such Securities to, but excluding, the repurchase date. Upon the occurrence of an Event of Loss Repurchase Event, unless the Company shall have exercised its option pursuant to Section 5 hereof to redeem Securities, the Company will be required to make an offer to all Holders of the Securities, to repurchase at least the Event of Loss Principal Amount (in denominations of a minimum principal amount of $2,000 and integral multiples of $1,000 in excess thereof) of the Securities at a repurchase price in cash equal to 100% of the aggregate principal amount of the Securities to be repurchased plus any accrued and unpaid interest on such Securities to, but excluding, the repurchase date.

8.	GUARANTEE. The payment by the Company of the principal of, and premium including the Make-Whole Premium, if any, and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior basis by each of the Guarantors to the extent set forth in the Indenture.

DENOMINATIONS; TRANSFER; EXCHANGE. The Securities are in registered form without coupons in denominations of a minimum principal amount of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and the Company will require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. Transfer may be restricted as provided in the Indenture.

10.	PERSONS DEEMED OWNERS. The registered Holder of this Security may be treated as the owner of it for all purposes.

11.

UNCLAIMED MONEY. If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

12.

DISCHARGE AND DEFEASANCE. Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its and any other Note Parties’ obligations under the Securities, the Securities Guarantees, the Indenture and the other Note Documents with respect to the Securities (including the Securities Guarantees) if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity (after deducting therefrom the amount contained in the Debt Service Reserve Account as of such date), as the case may be.

13.

AMENDMENT; SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Securities and the other Note Documents may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Outstanding Securities (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities), and any existing default or compliance with any provision of the Indenture,

Exhibit 1.1-6

the Securities or the other Note Documents may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Securities (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). Without the consent of any Holder of Securities, the Indenture, the Securities or the Security Documents may be amended or supplemented to, among other things, cure any ambiguity, to correct or supplement any provision which may be inconsistent with any other provision, or to make any other provisions with respect to matters or questions arising under the Indenture or other Note Documents, provided such action shall not adversely affect the interests of the Holders in any material respect, to release, terminate or discharge, or to confirm and evidence the release, termination or discharge of, any Collateral or any Securities Guarantee when permitted or required by this Indenture or the Security Documents or to amend or supplement any Security Document in accordance with the Indenture or the Security Document, including, without limitation, upon the replacement of a Collateral Rig Owner or in connection with a transfer of the Drilling Contract, in each case, in accordance with the Indenture.

14.

DEFAULTS AND REMEDIES. The Events of Default relating to the Securities are defined in Section 6.01 of the Indenture. Upon the occurrence of an Event of Default, the rights and obligations of the Company, the other Note Parties, the Trustee and the Holders shall be as set forth in the applicable provisions of the Indenture or other applicable Note Document.

15.	TRUSTEE DEALINGS WITH COMPANY. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may become a creditor of, or otherwise deal with the Company or any of its Affiliates, with the same rights it would have if it were not Trustee.

NO RECOURSE AGAINST OTHERS. A director, officer, employee or shareholder, as such, of the Company or any other Note Party shall not have any liability for any obligations of the Company under the Securities or this Indenture or of such Note Party under its Securities Guarantee, this Indenture or any other Note Document, as applicable, or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder shall waive and release all such liability. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

17.	SECURITY DOCUMENTS. The obligations of the Company and the other Note Parties under the Indenture, the Securities and the Security Documents will be secured by a Lien granted to the Collateral Agent on the Collateral.

18.	AUTHENTICATION. This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

Such Subsidiary possesses and is operating in compliance in all material respects with, all franchises, grants, authorizations, licenses, permits, easements, consents, certificates and orders of any governmental authority or self-regulatory body required for the conduct of its business and all such franchises, grants, authorizations, licenses, permits, easements, consents, certifications and orders are valid and in full force and effect, except where the failure to so possess or operate in compliance would not have a Material Adverse Effect, and such Subsidiary has not received notice of any revocation or modification of any such franchise, grant, authorization, license, permit, easement, consent, certification or order or has reason to believe that any such franchise, grant, authorization, license, permit, easement, consent, certification or order will not be renewed in the ordinary course, except where such revocation, modification or non-renewal would not have a Material Adverse Effect; and such Subsidiary is in compliance in all material respects with all applicable federal, state, local and foreign laws, regulations, orders and decrees, except where such non-compliance would not have a Material Adverse Effect on Holdings and its Subsidiaries, taken as a whole;

Each “employee benefit plan” established, maintained or contributed to by such Subsidiary or any of its ERISA Affiliates that has been determined by the Internal Revenue Service to be qualified under Section 401 of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.
