 EXECUTION VERSION 

This INDENTURE, dated as of November 30, 2018 is among VANTAGE DRILLING INTERNATIONAL, a Cayman Islands exempted company (the
“Company”), the Guarantors listed on the signature pages hereto and U.S. BANK NATIONAL ASSOCIATION, as Trustee and as collateral agent (the “First Lien Collateral Agent”). 

The Company, the Guarantors and the Trustee agree as follows for the benefit of each other and for the equal and ratable benefit of the
Holders (as defined herein) of (a) the Company’s 9.250% Senior Secured First Lien Notes due 2023 issued on the Issue Date (the “Initial Notes”) and (b) any Additional Notes (as defined herein) that may be issued after
the Issue Date (all such Notes in clauses (a) and (b) being referred to collectively as the “Notes”): 
 ARTICLE 1 

DEFINITIONS AND INCORPORATION BY REFERENCE 

SECTION 1.01. Definitions. 

“Acquired Debt” means, with respect to any specified Person: 

(1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Restricted
Subsidiary of such specified Person (regardless of the form of the applicable transaction by which such Person became a Subsidiary) or expressly assumed in connection with the acquisition of assets from any other such Person; and 

(2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person. 

Acquired Debt will be deemed to be Incurred on the date the acquired Person becomes a Restricted Subsidiary of such Person or the date of the
acquisition of assets from such Person, as applicable. 
 “Additional Notes” means Notes issued under this Indenture after
the Issue Date and in compliance with Sections 2.14 and 4.09, it being understood that any Notes issued in replacement of any Initial Note shall not be an Additional Note. 

“Additional Secured Debt Designation” means the written agreement of the First Lien Representative of holders of any series
of First Lien Debt or the Junior Lien Representative of holders of any series of Junior Lien Debt, as applicable, as set forth in the indenture, credit agreement or other agreement governing such series of First Lien Debt or series of Junior Lien
Debt, for the benefit of (i) all holders of existing and future First Lien Debt, the First Lien Collateral Agent and each existing and future holder of First Liens, in the case of each additional series of First Lien Debt and (ii) all
holders of each existing and future series of Junior Lien Debt, the applicable Junior Lien Collateral Agent and each existing and future holder of Junior Liens, in the case of each series of Junior Lien Debt: 

(1) in the case of any additional series of First Lien Debt, that all such First Lien Obligations will be and are secured equally and ratably
by all First Liens at any time granted by the Company or any Guarantor to secure any Obligations in respect of such series of First Lien Debt, whether or not upon property otherwise constituting collateral for such series of First Lien Debt, and
that all such First Liens will be enforceable by the First Lien Collateral Agent for the benefit of all holders of First Lien Obligations, equally and ratably, in each case subject to the exceptions that are applicable to Indebtedness incurred
pursuant to clause (3)(b) of Section 4.09(b); 
 (2) in the case of any additional series of Junior Lien
Debt, that all such Junior Lien Obligations will be and are secured equally and ratably by all Junior Liens at any time granted by the Company or any Guarantor to secure any Obligations in respect of such series of Junior Lien Debt, whether or not
upon property otherwise constituting collateral for such series of Junior Lien Debt, and that all such Junior Liens will be enforceable by the Junior Lien Collateral Agent for the benefit of all holders of Junior Lien Obligations, equally and
ratably; 











 (3) that such First Lien Representative or Junior Lien Representative, as applicable, and
the holders of Obligations in respect of such series of First Lien Debt or series of Junior Lien Debt, as applicable, are bound by the provisions of the Intercreditor Agreement, including the provisions relating to the ranking of First Liens and
Junior Liens and the order of application of proceeds from the enforcement of First Liens and Junior Liens; and 
 (4) appointing the First
Lien Collateral Agent or the Junior Lien Collateral Agent, as applicable, and consenting to the terms of the Intercreditor Agreement and, in the case of any additional series of First Lien Debt, the Collateral Agency Agreement, and the performance
by the First Lien Collateral Agent or the Junior Lien Collateral Agent, as applicable, of, and directing the First Lien Collateral Agent or the Junior Lien Collateral Agent, as applicable, to perform, its obligations under the Collateral Agency
Agreement (if applicable) and any other applicable security documents and the Intercreditor Agreement, together with all such powers as are reasonably incidental thereto. 

“Affiliate” means, with respect to any specified Person, any other Person directly or indirectly controlling or controlled by
or under direct or indirect common control with such specified Person. For the purposes of this definition, “control,” when used with respect to any specified Person, means the power to direct or cause the direction of the management and
policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise. For purposes of this definition, the terms “controlling,” “controlled by” and “under common
control with” have correlative meanings. 
 “Agent Members” has the meaning provided in the Appendix. 

“Agents” shall mean, collectively, the Trustee, the First Lien Collateral Agent, the Registrar, the Paying Agent and
any other agents under the Note Documents from time to time. 
 “Applicable Premium” means, with respect to any Note
on any redemption date, the greater of: 
 (1) 1.0% of the principal amount of the Note; and 

(2) the excess of: (a) the present value at such redemption date of (i) the redemption price of the Note at
May 15, 2020 (such redemption price being set forth in the table appearing in Section 3.07(d), excluding accrued and unpaid interest and Additional Amounts to the redemption date), plus (ii) all required interest
payments due on the Note through May 15, 2020 (excluding accrued but unpaid interest and Additional Amounts to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over
(b) the principal amount of the Note. 
 “Appraised Market Value” means, for any Vessel, its value as may be
determined from time to time based upon a valuation addressed to the First Lien Collateral Agent and the Trustee and prepared: 
 (1) with or
without a physical inspection of the Vessel and expressed in U.S. dollars on the basis of a sale for prompt delivery, charter-free, at arm’s-length between a willing seller and a willing buyer; 

(2) by any Approved Shipbroker; 

(3) without interrupting the operation or trading of the Vessel; and 

(4) not earlier than six months prior to the date of the incurrence of the relevant Indebtedness. 

  
 2 












 The Appraised Market Value shall be the value as stated in such valuation, except that: 

(a) if the Vessel is subject to a mortgage under which the amount recoverable by the applicable mortgagee is restricted to a registered maximum
mortgage amount, the market value of the Vessel shall be restricted to that mortgage amount if the valuation otherwise determined under this definition would be higher; and 

(b) if the Vessel becomes subject to an Involuntary Transfer after the date of the relevant appraisal, such Vessel shall be deemed to have an
Appraised Market Value of zero. 
 For the avoidance of doubt, the Appraised Market Value of any Vessel whose most recent valuation occurred
earlier than six months prior to the date of the incurrence of the relevant Indebtedness shall be deemed to be zero. 
 “Approved
Flag State” means any of the Republic of the Marshall Islands, the Republic of Liberia, the Republic of Panama, the Commonwealth of Bahamas, Singapore, the Commonwealth of Bermuda, the British Virgin Islands, Gibraltar, the Cayman Islands,
the Isle of Man, Cyprus, Norway, Greece, Hong Kong, the United Kingdom, any Member State of the European Union and any other jurisdiction generally acceptable to institutional lenders in the shipping and offshore drilling industries, as determined
in good faith by the Board of Directors of the Company. 
 “Approved Shipbrokers” means Artic Shipping AS, Clarkson Platou
AS, Pareto Shipbrokers AS, Fearnley Offshore AS, Pareto Bassøe Shipbrokers AS and such other independent and reputable offshore ship sale and purchase broker as may from time to time be selected by the Company in good faith for the purposes
of determining a Vessel’s Appraised Market Value. 
 “Asset Sale” means: 

(1) any sale, assignment, transfer, conveyance or other disposition (including by means of amalgamation, merger, consolidation
or similar transaction), whether in a single transaction or a series of related transactions, of property or assets of the Company or any of the Restricted Subsidiaries, including any disposition by means of a merger, consolidation or similar
transaction; provided that the sale, assignment, transfer, conveyance or other disposition of all or substantially all of the assets of the Company and the Restricted Subsidiaries, taken as a whole, will not be an “Asset Sale,” but
will be governed by the provisions of Section 4.15 and/or the provisions of Section 5.01 and not by the provisions of Section 4.10; 

(2) the issuance or sale of Equity Interests of any Restricted Subsidiary, other than directors’ qualifying shares and/or
other Equity Interests that are required to be held by any Persons other than the Company or another Restricted Subsidiary under applicable law or regulation (including local content regulations or requirements), whether in a single transaction or a
series of related transactions; and 
 (3) an Involuntary Transfer. 

Notwithstanding the preceding, none of the following items will be deemed to be an Asset Sale under clause (1) or (2) above: 

(1) any single transaction or series of related transactions that involves assets having a Fair Market Value of less than
$10 million (and the sale of such assets generates Net Proceeds of less than $10 million); 
 (2) a transfer of Equity
Interests or other assets between or among the Company and the Restricted Subsidiaries; 
 (3) an issuance of Equity
Interests by a Restricted Subsidiary to the Company or to another Restricted Subsidiary; 

  
 3 












 (4) the sale, transfer, lease,
sub-lease or other disposition of products, services or accounts receivable or any charter (including, for the avoidance of doubt, any bareboat charter), pool agreement, drilling contract or lease of a Vessel
and any related assets in the ordinary course of business and any sale or conveyance or other disposition of damaged, worn-out, obsolete, unnecessary or redundant assets in the ordinary course of business or
dispositions of property no longer used, useful or economically practicable to maintain in the conduct of the business of the Company and the Restricted Subsidiaries; 

(5) sales of assets to any customer purchased on behalf of or at the request of such customer in the ordinary course of
business; 
 (6) the sale or other disposition of cash or Cash Equivalents, hedging contracts or other financial instruments;

 (7) licenses and sublicenses by the Company or any of the Restricted Subsidiaries of software or intellectual property in
the ordinary course of business; 
 (8) a Restricted Payment that does not violate Section 4.07 or
a Permitted Investment; 
 (9) the creation or perfection of any Lien permitted under this Indenture, and any disposition of
assets constituting Collateral resulting from foreclosure under any such Lien by the First Lien Collateral Agent, or any disposition of assets not constituting Collateral resulting from foreclosure under any such Lien; 

(10) any surrender or waiver of contract rights or the settlement, release, recovery on or surrender of contract, tort or other
claims; 
 (11) any Permitted Asset Swap; and 

(12) any Sale and Lease-Back Transaction with respect to property constructed or acquired by the Company or any of the
Restricted Subsidiaries after the Issue Date that is entered into within twelve months of the construction or acquisition of such property, as applicable, other than a Sale and Lease-Back Transaction involving a Vessel. 

“Attributable Indebtedness” in respect of a Sale and Lease-Back Transaction means, at the time any determination is to be made, the
present value (discounted according to GAAP at the cost of indebtedness implied in the lease; provided that if such discount rate cannot be determined in accordance with GAAP, the present value shall be discounted at the interest rate borne
by the Notes, compounded annually) of the total obligations of the lessee for rental payments during the remaining term of the lease included in such Sale and Lease-Back Transaction (including any period for which such lease has been extended);
provided, however, that if such Sale and Lease-Back Transaction results in a Capital Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Capital Lease
Obligation.” 
 “Bankruptcy Law” means Title 11 of the United States Code, as may be amended from time to time,

 SECTION 2.01.
Form and Dating. 
 Provisions relating to the Notes are set forth in the Rule 144A/Regulation S Appendix attached hereto (the
“Appendix”), which is hereby incorporated in and expressly made part of this Indenture. The Notes and the Trustee’s certificate of authentication therefor shall be substantially in the form of Exhibit 1 to the Appendix,
which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have other notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The
terms of the Notes set forth in the Appendix are part of the terms of this Indenture. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

The terms and provisions contained in the Appendix and the Notes shall constitute, and are hereby expressly made, a part of this Indenture and
the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture or a supplemental indenture hereto, as applicable, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any such
provision conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 

SECTION 2.02. Execution and Authentication. 

At least one Officer of the Company shall sign the Notes on behalf of the Company by manual or facsimile signature. 

If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid
nevertheless. 
 A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on
the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

 On the Issue Date, the Trustee shall authenticate and deliver Notes in an aggregate
principal amount of $350,000,000 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount specified in an authentication order of the Company. Such order
shall specify the aggregate principal amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated and to whom the Notes shall be registered and delivered and, in the case of an issuance of Additional
Notes pursuant to Section 2.14 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09, 

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Notes. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Notes 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

The Company shall at all times maintain an office or agency in the United States where Notes may be presented for registration of transfer or
for exchange (the “Registrar”) and an office or agency in the contiguous United States where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes
and of their transfer and exchange (the “Register”). The Company may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any
co-registrar, and the term “Paying Agent” includes any additional paying agent. 
 The
Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in
writing of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such. Other than for purposes of effecting a redemption or an offer to purchase described in Sections
3.07, 3.08, 3.09, 4.10 and 4.15 or in connection with Legal Defeasance, Covenant Defeasance or Discharge, the Company or any of its Subsidiaries may act as Paying Agent or Registrar. 

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Notes at the Corporate Trust Office of the
Trustee. 
 SECTION 2.04. Paying Agent to Hold Money in Trust. 

Prior to 11:00 a.m. New York City time, on each date on which any principal, premium, if any, or interest on any Note is due and payable, the
Company shall deposit with the Paying Agent a sum sufficient to pay such principal, premium, if any, and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent
shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes and shall notify the Trustee of any
default by the Company in making any such payment. If the Company or any of its Subsidiaries acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund for the benefit of the Holders. The
Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Event of Default under Section 6.01(a) or
(b), upon written request to a Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums so held in trust by such Paying Agent and, in each case, to account for any funds disbursed by such Paying Agent. Upon complying
with this Section, the Paying Agent (if other than the Company or any of its Subsidiaries) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company,
the Trustee shall serve as Paying Agent for the Notes. 

  
 32 












 SECTION 2.05. Holder Lists. 

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. 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 and at such other times as the Trustee may 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. 
 SECTION 2.06. Transfer and Exchange.

 The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and
in compliance with the Appendix. When a Note is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of
this Indenture are met. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. The
Company may require payment of a sum sufficient to cover any taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section 2.06 (other than any such transfer taxes,
assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.08, 3.09, 4.10, 4.15 or 9.05). 

SECTION 2.07. Replacement Notes. 

If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate a replacement Note if the requirements of Section 8-405 of the Uniform
Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Registrar or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee to protect the
Registrar, Paying Agent and the Trustee and in the judgment of the Company to protect the Company from any loss which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a
Note. 
 Every replacement Note is an additional obligation of the Company. 

SECTION 2.08. Outstanding Notes. 

The Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in interests in a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09, a Note does not cease to be outstanding because the Company, any Guarantor or an Affiliate of the Company or any Guarantor holds the Note. 

If the Paying Agent (other than the Company or a Subsidiary thereof) holds in trust, in accordance with this Indenture, by 11:00 a.m. New York
City time, on a redemption date or other maturity date money sufficient to pay all principal, interest, premium, if any, and Additional Amounts, if any, payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing,
as the case may be, then on and after that date such Notes (or portions thereof) shall cease to be outstanding and interest on them shall cease to accrue. 

SECTION 2.09. Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company or any Guarantor, or by any Affiliate of the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction,
waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded. Notwithstanding anything in this Indenture to the contrary, no Person shall be deemed or presumed to have any such controlling interest, or to be
under common 

  
 33 












 
control of any other Person with the Company or any Guarantor, solely as a result of (i) such Person and/or such other Person being or becoming a party to the Shareholders Agreement
(including exercising its rights thereunder) or (ii) such Person and/or such other Person being a Beneficial Owner of more than 10% of the Company’s outstanding Voting Stock, unless, in the case of the preceding clause (ii), such Person
and/or such other Person (as determined in good faith by the Board of Directors of the Company) has the power, directly or indirectly, to direct or cause the direction of the management and policies of the Company, whether through the ownership of
the Voting Stock of the Company, by contract (excluding for such purposes the Shareholders Agreement), or otherwise (excluding for all such purposes any shares of the Company’s Voting Stock held by any other party subject to the Shareholders
Agreement attributable to such Person or such other Person as a result of the Shareholders Agreement). 
 SECTION 2.10. Temporary Notes.

 Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall, upon its receipt of an authentication order
from the Company, authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate definitive Notes and deliver them in exchange for Temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits under this Indenture. 

SECTION 2.11. Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange, replacement or payment. The Trustee and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration
of transfer, exchange, replacement, payment or cancellation. Upon written request, the Trustee will deliver a certificate of such cancellation to the Company. The Company may not issue new Notes to replace Notes it has redeemed, paid or delivered to
the Trustee for cancellation. 
 SECTION 2.12. Defaulted Interest. 

If the Company defaults in a payment of interest on the Notes, the Company shall pay defaulted interest at the rate specified in the second
paragraph of Section 4.01 (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 on a subsequent special record date.
The Company shall fix or cause to be fixed any such special record date and payment date (which special record date shall not be less than 10 days prior to the related payment date) to the reasonable satisfaction of the Trustee and shall promptly
mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 

SECTION 2.13. CUSIP and ISIN Numbers. 

The Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so,
the Trustee shall use “CUSIP” numbers and corresponding “ISINs” 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 Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any changes in “CUSIP” or “ISIN” numbers. 

SECTION 2.14. Issuance of Additional Notes. 

The Company shall be entitled, subject to its compliance with Sections 4.09 and 4.12, to issue Additional Notes under this
Indenture, which Additional Notes shall have identical terms and conditions as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, issue price and the date from which interest will accrue. The Initial Notes
issued on the Issue Date, and any Additional Notes, will be equally and 

  
 34 












 
ratably secured by the Liens granted to the First Lien Collateral Agent on the Collateral and shall be treated as a single class for all purposes under this Indenture, including, without
limitation, waivers, amendments, redemptions and offers to purchase; provided, however, that in the event any Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such
non-fungible Notes will be issued with a separate CUSIP or ISIN number so they are distinguishable from the Notes issued on the Issue Date. 

With respect to any Additional Notes, the Company shall set forth in an Officers’ Certificate, which shall be delivered to the Trustee,
the following information: 
 (1) the aggregate principal amount of such Additional Notes to be authenticated and delivered
pursuant to this Indenture and the provision of Section 4.09 that the Company is relying on to issue such Additional Notes; and 

(2) the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and the first Interest
Payment Date therefor) and the CUSIP number and any corresponding ISIN of such Additional Notes. 
 ARTICLE 3 

REDEMPTION AND PREPAYMENT 

SECTION 3.01. Notices to Trustee. 

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 or is required
to redeem, or offer to redeem, Notes pursuant to Section 3.08, it shall furnish to the Trustee, at least five Business Days (unless a shorter period shall be agreeable to the Trustee) before the date of giving notice of the
redemption pursuant to Section 3.03, an Officers’ Certificate setting forth (i) either the clause of Section 3.07 pursuant to which the redemption shall occur or that such redemption
shall occur pursuant to Section 3.08, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed, (iv) the redemption price or the method by which it will be determined, and (v) whether the
Company requests that the Trustee give notice of such redemption. 
 SECTION 3.02. Selection of Notes to Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes to be redeemed on a pro rata basis,
unless otherwise required by law or applicable stock exchange or Depository requirements, from the outstanding Notes not previously called for redemption. In the event of partial redemption other than on a pro rata basis, the particular Notes
to be redeemed shall be selected, not less than five Business Days (unless a shorter period shall be agreeable to the Trustee) prior to the giving of notice of the redemption pursuant to Section 3.03, by the Trustee from
the outstanding Notes not previously called for redemption. 
 The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. No Notes of $2,000 or less can be redeemed in part. Notes and portions of Notes selected shall be in amounts of $2,000
or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption. 
 SECTION 3.03. Notice of Redemption. 

Except as otherwise provided in Section 3.08, at least 30 days but not more than 60 days before a redemption date (except that redemption
notices may be delivered more than 60 days prior to a redemption date if the notice is issued in connection with a Legal Defeasance, Covenant Defeasance or Discharge), the Company shall mail or cause to be mailed, by first class mail, or otherwise
given in accordance with the procedures of the Depository, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee). Notices of redemption may be subject to one or more conditions
specified in the notice of redemption. 

  
 35 












 The notice shall identify the Notes to be redeemed and shall state: 

(a) the redemption date; 

(b) the redemption price or, if the redemption price is not then determinable, the manner in which it is to be determined; 

(c) if any Note is to be redeemed in part only, the portion of the principal amount of such Note that is to be redeemed and
that, after the redemption date upon surrender of such Note, a new Note or Notes in a principal amount equal to the unredeemed portion of the original Note will be issued in the name or transferred by book entry to the applicable Holder upon
cancellation of the original Note; 
 (d) the name and address of the Paying Agent; 

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(f) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption shall cease to
accrue on and after the redemption date and the only remaining right of the Holders of such Notes is to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed; 

(g) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being
redeemed; 
 (h) the CUSIP (or ISIN) number, if any, and that no representation is made as to the correctness or accuracy of
the CUSIP (or ISIN) number, if any, listed in such notice or printed on the Notes; and 
 (i) a description of any conditions
to the Company’s obligations to complete the redemption. 
 If any of the Notes to be redeemed is in the form of a Global Note, then
the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to redemption. 
 At
the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, as provided in
Section 3.01, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the second preceding paragraph. 

SECTION 3.04. Effect of Notice of Redemption. 

Once notice of redemption is delivered in accordance with Section 3.03, Notes (or portions thereof) called for
redemption become irrevocably due and payable on the applicable redemption date at the applicable redemption price, subject to the satisfaction of any conditions to the redemption specified in the notice of redemption. If delivered in the manner
provided for in Section 3.03, the notice of redemption shall be conclusively presumed to have been given whether or not a Holder receives such notice. Failure to give timely notice or any defect in the notice shall not
affect the validity of the redemption. 

  
 36 












 SECTION 3.05. Deposit of Redemption Price. 

Prior to 11:00 a.m., New York City time, on any redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a
Subsidiary thereof is acting as Paying Agent, segregate and hold in trust as provided in Section 2.04) money sufficient in same day funds to pay the redemption price of and accrued interest on all Notes to be redeemed on
that date. The Paying Agent shall promptly return to the Company any money deposited with the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of and accrued interest on all Notes to be redeemed. 

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption whether or not such Notes are presented for payment, and the only remaining right of the Holders of such Notes shall be to receive payment of the redemption price upon surrender to the Paying
Agent of the Notes redeemed. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the
redemption date until such principal is paid, and to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01. 

SECTION 3.06. Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Company shall issue in the name of the applicable Holder and the Trustee shall, upon
its receipt of an authentication order from the Company, authenticate and mail to such Holder (or cause to be transferred by book entry) at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note
surrendered representing the same Indebtedness to the extent not redeemed; provided that each new Note shall be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof. It is understood that, notwithstanding
anything in this Indenture to the contrary, only an authentication order and not an Opinion of Counsel or Officers’ Certificate is required for the Trustee to authenticate such new Note. 

SECTION 3.07. Optional Redemption. 

(a) At any time prior to May 15, 2020, the Company may, at its option, redeem up to 35% of the aggregate principal amount of Notes
(including any Additional Notes) issued under this Indenture, at one time or from time to time, at a redemption price equal to 109.250% of the principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, to, but not
including, the applicable redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in an amount not greater than the net cash proceeds received by the
Company from one or more Equity Offerings; provided that: 
 (1) at least 65% of the aggregate principal amount of
Notes (including any Additional Notes) issued under this Indenture (excluding any Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 

(2) the redemption occurs within 120 days after the date of the closing of such Equity Offering. 

(b) At any time prior to May 15, 2020, the Company may, at its option, redeem the Notes, in whole or in part, at one time or from time to
time, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional Amounts, if any, to, but not including, the applicable redemption date,
subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date. The Company shall calculate, or cause the calculation of, the Applicable Premium and the Trustee shall have no duty
to calculate or verify the Company’s calculations thereof. 
 (c) At any time prior to May 15, 2020, not more than once in any 12-month period, the Company may, at its option, redeem up to $35.0 million in aggregate principal amount of the Notes at a redemption price equal to 103% of the aggregate principal amount thereof, plus accrued
and unpaid interest and Additional Amounts, if any, to, but not including, the redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date. 

  
 37 












 (d) On or after May 15, 2020, the Company may, at its option, redeem the Notes, in
whole or in part, at one time or from time to time, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed, to, but not
including, the applicable redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on May 15 of
the years indicated below: 
  

					
	 YEAR
	  	PERCENTAGE	 
	 2020
	  	 	104.625	% 
	 2021
	  	 	102.3125	% 
	 2022 and thereafter
	  	 	100.000	% 

 (e) The Company may redeem the Notes, at its option, at any time in whole but not in part, at a redemption
price equal to 100% of the outstanding principal amount of Notes, plus accrued and unpaid interest (if any) to, but not including, the applicable redemption date, plus all Additional Amounts, if any, then due and which will become due as a result of
the redemption or otherwise (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in the event that the Company determines in good faith that the Company or any
Guarantor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes or the Guarantees, Additional Amounts, and such obligation cannot be avoided by taking reasonable measures
available to the Company or the relevant Guarantor, as applicable (including making payment through a Paying Agent located in another jurisdiction but not, for the avoidance of doubt, changing the jurisdiction of incorporation of the Company or the
relevant Guarantor ), as a result of: 
 (1) a change in or an amendment to the laws or treaties (including any regulations
or rulings promulgated thereunder) of any Specified Tax Jurisdiction affecting taxation, which change or amendment is announced or becomes effective on or after the Issue Date (or, if the Specified Tax Jurisdiction was not a Specified Tax
Jurisdiction on the Issue Date, the date on which such Specified Tax Jurisdiction became a Specified Tax Jurisdiction); or 

(2) any change in or amendment to any official position of a taxing authority in any Specified Tax Jurisdiction regarding the
application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after the
Issue Date (or, if the Specified Tax Jurisdiction was not a Specified Tax Jurisdiction on the Issue Date, the date on which such Specified Tax Jurisdiction became a Specified Tax Jurisdiction); 

provided, however, that in the case of Additional Amounts required to be paid as a result of the Company or relevant Guarantor conducting
business other than in the place of its incorporation or organization, such amendment or change must be announced or become effective on or after the date in which it begins to conduct business giving rise to the relevant withholding or deduction.

 Notwithstanding the foregoing, no such notice of redemption may be given earlier than 60 days prior to the earliest date on which the
Company or the relevant Guarantor, as applicable, would be obligated to pay Additional Amounts if a payment in respect of the Notes or the Guarantees were then due, and at the time such notice is given, the obligation to pay Additional Amounts must
remain in effect. Before the Company mails or delivers notice of redemption of the Notes as described above, the Company shall deliver to the Trustee and Paying Agent (a) an Officers’ Certificate stating that the Company is entitled to
effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred and (b) an opinion of independent legal counsel of recognized standing that the Company
or any Guarantor has or will become obligated to pay Additional Amounts as a result of the circumstances referred to in clause (1) or (2) of the preceding paragraph. 

The Trustee and Paying Agent will be entitled to conclusively rely upon the Officers’ Certificate and opinion of counsel as sufficient
evidence of the satisfaction of the conditions precedent described above, in which case they will be conclusive and binding on the Holders. 

  
 38 












 (f) If a Change of Control occurs at any time on or after May 15, 2019, the Company may
redeem the Notes, at its option, in whole but not in part, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed, to, but not
including, the applicable redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date, if redeemed during the periods below: 

 

					
	 Period
	  	Percentage	 
	 From and after May 15, 2019 to, but excluding, November 15, 2019
	  	 	106.9375	% 
	 From and after November 15, 2019 to, but excluding, May 15, 2021
	  	 	104.625	% 
	 From and after May 15, 2021 to, but excluding, May 15, 2022
	  	 	102.3125	% 
	 From and after May 15, 2022
	  	 	100.000	% 

 If the Company elects to exercise this redemption right, it must do so by delivering a redemption
notice to each holder with a copy to the Trustee within 60 days following the Change of Control (or, at the Company’s option, prior to such Change of Control but after the transaction giving rise to such Change of Control is publicly
announced). Any such redemption may be conditioned upon the Change of Control occurring if the notice is delivered prior to the Change of Control. If the Company exercises the Change of Control redemption right, it may elect not to make the Change
of Control Offer pursuant to Section 4.15(a) unless it defaults in payments due upon redemption. Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the notes called for
redemption on the applicable redemption date. 
 (g) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through Section 3.05. 
 SECTION 3.08.
Mandatory Petrobras Offer 
 (a) At such time as the Company or any Restricted Subsidiary has received Petrobras Recovery Proceeds in the
form of cash or Cash Equivalents of at least $75 million, the Company shall, within 10 Business Days of receipt thereof make an offer (a “Petrobras Offer”) to all Holders (and holders of any other First Lien Debt containing
provisions similar to those set forth in this Indenture with respect to offers to purchase, repay or redeem such First Lien Debt with Petrobras Recovery Proceeds) to purchase Notes (and to purchase, repay or redeem such other First Lien Debt on a
pro rata basis) in an aggregate principal amount equal to at least $75 million (the “Designated Petrobras Amount”). 

(b) The repurchase date in any Petrobras Offer (the “Petrobras Offer Settlement Date”) shall be specified by the
Company, and, subject to the final sentence of this clause (b), shall be no earlier than 30 days and no later than 60 days from the date the notice of such Petrobras Offer is delivered pursuant to clause (c) below. The offer, repayment or
redemption price in any Petrobras Offer will be equal to 100% of the principal amount of Notes or other First Lien Debt to be repurchased, repaid or redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to, but not including,
the date of repurchase, repayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. A Petrobras Offer shall remain open for a
period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Petrobras Offer Period”).  

(c) Upon the commencement of a Petrobras Offer, the Company shall send, by first class mail, or otherwise in accordance with the requirements
of the Depository, a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Petrobras Offer. The notice, which shall govern
the terms of the Petrobras Offer, shall state: 
 (i) that the Petrobras Offer is being made pursuant to this
Section 3.08 and the duration of the Petrobras Offer Period, including the time and date the Petrobras Offer Period will terminate (the “Petrobras Offer Termination Date”); 

  
 39 












 (ii) the Designated Petrobras Amount and the purchase price; 

(iii) that any Note not tendered or accepted for payment shall continue to accrue interest; 

(iv) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Petrobras Offer
shall cease to accrue interest on and after the Petrobras Offer Settlement Date; 
 (v) that Holders electing to have a Note
purchased pursuant to the Petrobras Offer shall be required to surrender the Note, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed and such customary
documents as the Company may reasonably request, to the Company or a Paying Agent at the address specified in the notice, before the Petrobras Offer Termination Date; 

(vi) that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be,
receives, prior to the Petrobras Offer Termination Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing its
election to have such Note purchased; 
 (vii) that, if the aggregate principal amount of Notes and other First Lien Debt
tendered in such a Petrobras Offer collectively exceeds the Designated Petrobras Amount, the Company will select the Notes and such other First Lien Debt for purchase, repayment or redemption on a pro rata basis unless otherwise required by
law or applicable stock exchange or Depository requirements (with such adjustments as may be deemed appropriate by the Company so that only Notes and other First Lien Debt in denominations of $2,000 and integral multiples of $1,000 in excess thereof
will be outstanding after such repurchase, repayment or redemption); and 
 (viii) that Holders whose Notes were purchased
only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 

(d) Promptly after the Petrobras Offer Termination Date, the Company shall, to the extent lawful, accept for payment Notes or portions thereof
properly tendered and not withdrawn pursuant to the Petrobras Offer in the aggregate principal amount required by this Section 3.08. Prior to 11:00 a.m., New York City time, on the Petrobras Offer Settlement Date, the
Company, the Depository or the Paying Agent, as the case may be, shall mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company
shall promptly issue a new Note, and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder, in a principal amount
equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. 

(e) Any Petrobras Recovery Proceeds in the form of cash or Cash Equivalents in excess of the Designated Petrobras Amount or that remain after
consummation of a Petrobras Offer may be used by the Company and the Restricted Subsidiaries for any purpose not otherwise prohibited by this Indenture. For the purposes of this Section 3.08, any cash proceeds from the
Petrobras Award not denominated in U.S. dollars shall be converted into their Dollar Equivalent determined as of the Business Day immediately prior to the date on which the Petrobras Offer is announced. 

  
 40 












 (f) The Company shall comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those requirements, laws and regulations are applicable in connection with each repurchase of Notes or any
other First Lien Debt pursuant to a Petrobras Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 3.08, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached this Section 3.08 by virtue of such compliance. 
 (g) The
provisions of this Section 3.08 may be waived or modified at any time with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. 

SECTION 3.09. Offer to Purchase by Application of Excess Proceeds. 

(a) In the event that, pursuant to Section 4.10, the Company shall be required to commence an Asset Sale Offer, it
shall follow the additional procedures specified below. 
 (b) Each Asset Sale Offer shall remain open for a period of at least 20 Business
Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Asset Sale Offer Period”). No later than five Business Days after the
termination of the Asset Sale Offer Period (the “Asset Sale Offer Settlement Date”), the Company shall apply all Excess Proceeds (the “Asset Sale Offer Amount”) to the purchase of the Notes and other
Indebtedness of the Company or the applicable Restricted Subsidiary as specified in Section 4.10 or, if less than the Asset Sale Offer Amount has been validly tendered (and not validly withdrawn), all Notes and other
Indebtedness of the Company or such Restricted Subsidiary, as applicable, validly tendered (and not validly withdrawn) in response to the Asset Sale Offer. 

(c) Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, or otherwise in accordance with the
requirements of the Depository, a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale
Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state: 
 (i)
that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 and the length of time the Asset Sale Offer shall remain open, including the time and date the Asset Sale
Offer will terminate (the “Asset Sale Offer Termination Date”); 
 (ii) the Asset Sale Offer Amount, the
purchase price and the Asset Sale Offer Settlement Date; 
 (iii) that any Note not tendered or accepted for payment shall
continue to accrue interest; 
 (iv) that, unless the Company defaults in making such payment, any Note accepted for payment
pursuant to the Asset Sale Offer shall cease to accrue interest on and after the Asset Sale Offer Settlement Date; 
 (v)
that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on the reverse of
the Note completed and such customary documents as the Company may reasonably request, to the Company or a Paying Agent at the address specified in the notice, before the Asset Sale Offer Termination Date; 

(vi) that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be,
receives, prior to the Asset Sale Offer Termination Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing its
election to have such Note purchased; 

  
 41 












 (vii) that, if the aggregate principal amount of Notes or other First Lien
Debt surrendered by Holders and holders of such other First Lien Debt, collectively, exceeds the Asset Sale Offer Amount, the Company shall select the Notes and such other First Lien Debt to be purchased from the amount allocated therefor on a
pro rata basis unless otherwise required by law or applicable stock exchange or Depository requirements (with such adjustments as may be deemed appropriate by the Company so that only Notes and First Lien Debt in denominations of $2,000 and
integral multiples of $1,000 in excess thereof will be outstanding after such purchase); and 
 (viii) that Holders whose
Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in
excess thereof. 
 Promptly after the Asset Sale Offer Termination Date, the Company shall, to the extent lawful, accept for payment Notes
or portions thereof tendered pursuant to the Asset Sale Offer in the aggregate principal amount required by Section 4.10. Prior to 11:00 a.m., New York City time, on the Asset Sale Offer Settlement Date, the Company, the
Depository or the Paying Agent, as the case may be, shall mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly
issue a new Note, and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. 

SECTION 3.10. No Mandatory Sinking Fund. 

Except as set forth under Sections 3.08, 4.10 and 4.15, the Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders.

COVENANTS 
 SECTION 4.01.
Payment of Notes. 
 The Company shall pay or cause to be paid the principal of, interest, premium, if any, on, the Notes on the dates and
in the manner provided in the Notes. Principal, interest and premium, if any, shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 a.m., New York City time, on the due
date money deposited by the Company or a Guarantor in immediately available funds and designated for and sufficient to pay all principal, interest and premium, if any, then due. Subject to Section 4.22, all payments made by
the Company under or with respect to the Notes will be made free and clear of and without withholding or deduction for, or on account of, any Taxes, unless the withholding or deduction of such Taxes is then required by law. 

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate
equal to the then-applicable interest rate on the Notes; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace
period), at the same rate as on overdue principal to the extent lawful. 
 SECTION 4.02. Maintenance of Office or Agency. 

The Company shall maintain an office or agency (which may be an office of the Trustee, an affiliate of the Trustee, the Registrar or the
Paying Agent) in the contiguous United States where Notes may be presented or surrendered for payment and shall maintain an office or agency in the contiguous United States (which may be an office of the Trustee, an affiliate of the Trustee, the
Registrar or the Paying Agent) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt
written notice to the Trustee 

  
 42 












 
of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee; provided that no office of the Trustee shall be an office or agency for the purpose of service
of legal process against the Company or any Guarantor. 
 The Company may also from time to time designate one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the contiguous United States for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any
such other office or agency. 
 The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the
Company in accordance with Section 2.03. 
 SECTION 4.03. Reports.

and the Holders, so long as any Notes are outstanding:

annual report on Form 10-K or (in the event the Company is a “foreign private issuer” subject to Section 13(a) or 15(d) of the Exchange Act) Form 20-F
(or, in each case, any successor form) containing, whether or not required, the Company’s audited consolidated financial statements, a report thereon by the Company’s certified independent accountants and an MD&A for such fiscal year;
and 
 (3) (i) at such times as would be required to be filed or furnished to the SEC if the Company was subject to

pursuant thereto; or (ii) in the event that the Company is a “foreign private issuer” subject to Section 13(a) or 15(d) of the Exchange Act, all such other reports and information that the Company is required to file or furnish
pursuant thereto. 
 All such reports shall be prepared in all material respects in accordance with all of the rules and regulations applicable to such
reports. 
 (b) The Company shall electronically file or furnish, as the case may be, a copy of all such information and reports referred to
in clauses (1) through (3) in paragraph (a) above with the SEC for public availability within the time periods specified therein at any time the Company is then subject to Section 13(a) or 15(d) of the Exchange Act and make such
information available to the Holders, and if the Notes are represented by one or more Global Notes, the beneficial owners, of the Notes and prospective investors upon request. 

  
 43 












 (c) The Company shall be deemed to have furnished such reports referred to in paragraph
(a) above to the Trustee and the Holders if the Company has filed such reports with the SEC via the EDGAR filing system and such reports are publicly available. If, notwithstanding the foregoing, the SEC will not accept the Company’s
filings for any reason, the Company will post the reports referred to in paragraph (a) above on its website within the time periods that would apply to non-accelerated filers if the Company were required
to file those reports with the SEC. The Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the EDGAR filing system (or its successor) or postings to any website
have occurred. 
 (d) The Company agrees that, for so long as any Notes remain outstanding, it will hold and participate in quarterly
conference calls with the Holders and securities analysts relating to the financial condition and results of operations of the Company and the Restricted Subsidiaries. 

(e) In addition, for so long as any Notes remain outstanding and are subject to restrictions on transfer by
non-Affiliates under U.S. federal securities laws, the Company will furnish to the Holders and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the U.S. Securities Act. 
 (f) If the Company has designated any Unrestricted Subsidiaries, then the quarterly and annual financial
information required by this Section 4.03 shall include a reasonably detailed presentation of the financial condition and results of operations of the Unrestricted Subsidiaries separate from the financial condition and
results of operations of the Company and the Restricted Subsidiaries. 
 (g) Delivery of reports, information and documents to the Trustee
pursuant to this Section 4.03 is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including
the Company’s compliance with the covenants hereunder (as to which the Trustee is entitled to conclusively rely exclusively on an Officers’ Certificate). 

SECTION 4.04. Compliance Certificate. 

(a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year ending after the Issue Date, an Officers’
Certificate stating (i) that a review of the activities of the Company and the Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company
has kept, observed, performed and fulfilled its obligations under this Indenture and the other Note Documents, and further stating, as to each such Officer signing such certificate, that, to the best of his or her knowledge, the Company has kept,
observed, performed and fulfilled each and every covenant contained in this Indenture and the other Note Documents applicable to the Company and is not in default in the performance or observance of any of the terms, provisions and conditions
thereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and
(ii) either (x) that all action has been taken with respect to the recording, filing, re-recording and refiling of this Indenture and all amendments, supplemental indentures, financing statements,
continuation statements and other documents, as are necessary to maintain the perfected Liens created under the Collateral Documents under applicable law and reciting the details of such action or referring to prior Officers’ Certificates in
which such details are given or (y) that no such action is necessary to maintain such Liens. 
 (b) The Company shall, so long as any
of the Notes are outstanding, deliver to the Trustee, within 10 Business Days of any of its Officers becoming aware of any Default or Event of Default, a written statement specifying the nature of such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto. 

  
 44 












 SECTION 4.05. Taxes. 

The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and
governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders. 

SECTION 4.06. Stay, Extension and Usury Laws. 

Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the
Company and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. 

SECTION 4.07. Limitation on Restricted Payments. 

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly: 

(1) declare or pay any dividend or make any other payment or distribution on account of Equity Interests of the Company or any
Restricted Subsidiary (including, without limitation, any payment in connection with any merger, consolidation or amalgamation involving the Company or any of the Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or
any of the Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company and other than dividends or distributions payable
to the Company or any other Restricted Subsidiary (and, if such Restricted Subsidiary has holders of Equity Interests other than the Company or other Restricted Subsidiaries, to its other holders of Equity Interests on a pro rata basis or on a basis
that is more favorable to the Company and the Restricted Subsidiaries than pro rata)); 
 (2) purchase, repurchase, redeem,
retire or otherwise acquire for value (including, without limitation, in connection with any merger, consolidation or amalgamation involving the Company) any Equity Interests of the Company held by any Person (other than any such Equity Interests
held by the Company or any Restricted Subsidiary) or any Equity Interests of any Restricted Subsidiary held by an affiliate of the Company (other than Equity Interests held by the Company or any Restricted Subsidiary) (in each case other than in
exchange for Equity Interests of the Company that do not constitute Disqualified Stock); 
 (3) make any cash interest
payment on or with respect to, or principal or premium payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, any Junior Debt; or

Payments”), unless, at the time of and after giving effect to such Restricted Payment: 
 (I) no Default or Event
of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; 
 (II) the Company
could Incur, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, at least $1.00 of additional Indebtedness pursuant to

 45 












 (III) such Restricted Payment, together with the aggregate amount of all
other Restricted Payments made by the Company and the Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by clauses (2) through (14) of Section 4.07(b)), is less than the sum, without
duplication, of: 
 (A) 50% of the Company’s Consolidated Net Income on a consolidated basis for the period (taken as
one accounting period) beginning on the first day of the first fiscal quarter after the Issue Date during which the Company’s Consolidated Net Income is positive (the “Builder Basket Start Date”) and ending on the last day of
the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit);
plus 
 (B) 100% of the aggregate net cash proceeds or the Fair Market Value of assets other than cash, in each case
received by the Company or any Restricted Subsidiary from any Person other than the Company or any of its Subsidiaries since the Builder Basket Start Date as a contribution to its common equity capital or from the issue or sale of the Equity
Interests (other than Disqualified Stock) of the Company or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Company, in each case that have been converted into or
exchanged for Equity Interests (other than Disqualified Stock) of the Company (other than Equity Interests, Disqualified Stock or debt securities sold to a Subsidiary of the Company); plus 

(C) 100% of the aggregate net cash proceeds or the Fair Market Value of assets other than cash, in each case received by the
Company or any Restricted Subsidiary from the sale or other disposition of, or other returns on Investment from, any Restricted Investment that was made after the Builder Basket Start Date pursuant to this paragraph or the Equity Interests of an
Unrestricted Subsidiary; plus 
 (D) to the extent that any Unrestricted Subsidiary designated as such after the
Builder Basket Start Date pursuant to this paragraph is redesignated as a Restricted Subsidiary or is merged, amalgamated or consolidated with (or substantially all of the assets of which are transferred to) the Company or a Restricted Subsidiary,
the Fair Market Value of the Restricted Investment made by the Company or any of the Restricted Subsidiaries in such Subsidiary as of the date of such redesignation. 

(b) The provisions of Section 4.07(a) will not prohibit: 

(1) the payment of any dividend or distribution or the consummation of any irrevocable redemption within 60 days after the date
of declaration of the dividend or distribution or the date of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend, distribution or redemption payment would have complied with the provisions of this
Indenture; 
 (2) so long as no Default or Event of Default has occurred and is continuing or would occur as a result
thereof, the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock) or
from the substantially concurrent contribution of common equity capital to the Company; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (III)(B) of
Section 4.07(a) above;

acquired or retired Equity Interests may not exceed $3 million in any twelve-month period (with any portion of such $3 million that is unused in any twelve-month period to be carried forward to successive twelve-month periods and added to
such amount); 
 (5) (a) the purchase, redemption or other acquisition or retirement for value of Equity Interests deemed to
occur upon the exercise or conversion of stock options, warrants, rights to acquire Equity Interests or other convertible securities, to the extent such Equity Interests represent a portion of the exercise or conversion price thereof, and
(b) the purchase, redemption, net-settlement, or other acquisition or retirement for value of Equity Interests of the Company or any Restricted Subsidiary held by any current or former officer, director
or employee of the Company or any Restricted Subsidiary in connection with the exercise, vesting or settlement of any equity compensation (including, without limitation, any Management Incentive Plan Awards or other stock option, restricted stock or
phantom stock award), in each case in this clause (b), solely in order to satisfy any tax withholding obligation with respect to such exercise, vesting or settlement; 

(6) any purchase, redemption, defeasance or other acquisition or retirement of any Junior Debt from proceeds of an Asset Sale
or Petrobras Award or in the event of a Change of Control, in each case only if prior to or simultaneously with such purchase, redemption, defeasance or other acquisition or retirement, the Company or a Restricted Subsidiary has made the Asset Sale
Offer, Petrobras Offer or Change of Control Offer, as applicable, as provided in this Indenture and has completed the repurchase of all Notes validly tendered for payment in connection with such Asset Sale Offer, Petrobras Offer or Change of Control
Offer in accordance with the requirements of this Indenture; 
 (7) so long as no Default or Event of Default has occurred

(9) so long as no Default or Event of Default has occurred and is continuing or would occur as a result thereof, any Restricted
Payment so long as the amount of such Restricted Payment, together with the aggregate amount of all other Restricted Payments made under this clause (9) since the Issue Date, does not exceed $15 million; 

(10) any Restricted Payment made with Petrobras Recovery Proceeds that remain after the consummation of a Petrobras Offer,
including, without limitation, by way of dividends or distributions to holders of Equity Interests in the Company; 

  
 47 












 (11) so long as no Default or Event of Default has occurred and is
continuing or would occur as a result thereof, any Restricted Payment so long as, at the time of, and after giving effect to, such Restricted Payment, the Company’s First Lien Leverage Ratio does not exceed 2.0 to 1.0;

 The amount of all Restricted Payments (other than
cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or any Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. For
purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in
Section 4.07(a) or the preceding clauses (1) through (14) of this Section 4.07(b) or as a Permitted Investment, the Company will be permitted to divide or classify (or later divide, classify
or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 4.07. 

Notwithstanding anything herein to the contrary, nothing in this Section 4.07 will prohibit the continued non-cash (“PIK”) interest payments on or conversion of the Existing Convertible Notes into Equity Interests of the Company in accordance with the terms of the indenture governing the terms of the Existing
Convertible Notes.

dividends or make any other distributions on its Capital Stock to the Company or any of the Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Company
or any of the Restricted Subsidiaries; provided that the priority that any series of preferred stock of a Restricted Subsidiary has in receiving dividends or liquidating distributions before dividends or liquidating distributions are paid in
respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends or distributions on Capital Stock for purposes of this Section 4.08; 

  
 48 












 (2) make loans or advances to the Company or any of the Restricted
Subsidiaries; or 
 (3) sell, or transfer any of its properties or assets to the Company or any of the Restricted
Subsidiaries (all such actions set forth in these clauses (1) through (3) being collectively referred to as “Intercompany Transfers”).

Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be
Incurred;

entered into in the ordinary course of business; 
 (7) purchase money obligations for property acquired in the ordinary
course of business, mortgage financings and Capital Lease Obligations that impose restrictions on the property purchased or mortgaged of the nature described in clause (3) of Section 4.08(a); 

(8) any agreement for the sale or other disposition of the Capital Stock or all or substantially all of the assets of any
Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending the sale or other disposition;

debtor to dispose of the assets subject to such Liens;

(13) instruments governing Indebtedness, Disqualified Stock or Preferred Stock that is permitted to be Incurred subsequent to
the Issue Date pursuant to Section 4.09; provided that, at the time such Indebtedness is Incurred, either (a) such encumbrances or restrictions would not 

  
 49 












 
reasonably be expected to materially impair the Company’s ability to make scheduled payments of interest and principal on the Notes when due or any Guarantor’s ability to make payment
under its Guarantee, as determined in good faith by the Board of Directors of the Company or a Financial Officer of the Company, or (b) the restrictions therein are not materially more restrictive, taken as a whole, than those contained in this
Indenture and the Notes, as determined in good faith by the Board of Directors or a Financial Officer of the Company; 
 (14)
restrictions contained in Hedging Obligations permitted under this Indenture; 
 (15) customary provisions in joint venture

 (16) any
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (15) above; provided that such
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company, not materially more restrictive with respect to such encumbrance and other
restrictions taken as a whole than those prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing. 

SECTION 4.09. Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock. 

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “Incur,” and “Incurrence,” “Incurred” and
“Incurring” shall have meanings correlative to the foregoing) any Indebtedness (including Acquired Debt) or issue any Disqualified Stock, and the Company will not permit any of the Restricted Subsidiaries to issue any shares
of Preferred Stock; provided, however, that the Company or any Guarantor may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or Preferred Stock in an amount equal to the greater of (i) an amount such that,
after giving effect to such Incurrence or issuance and the application of the proceeds therefrom, the Consolidated Interest Coverage Ratio would have been at least 2.0 to 1.0 and (ii) an amount such that, after giving effect to such Incurrence
or issuance and the application of the proceeds therefrom (including the acquisition of any Collateral Vessel or other Collateral constituting marine spare parts and equipment held in inventory (as reflected on the consolidated balance sheet of the
Company) or onboard Collateral Vessels), the aggregate amount of Consolidated Total Indebtedness of the Company and the Restricted Subsidiaries (including any outstanding Notes and any Permitted Refinancing Indebtedness in respect thereof, but
excluding any Existing Convertible Notes and intercompany Indebtedness permitted by clause (5) of Section 4.09(b)) does not exceed 60% of the sum, without duplication, of (x) the Appraised Market Value of the
Collateral Vessels and (y) the Fair Market Value (as determined by a recent appraisal of a qualified independent third party) of any other Collateral constituting marine spare parts and equipment held in inventory (as reflected on the
consolidated balance sheet of the Company) or onboard Collateral Vessels. 
 (b) The provisions of Section 4.09(a)
will not, however, prohibit the Incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 

(1) the Incurrence by the Company or any Guarantor of Indebtedness under the Notes and the Guarantees thereof issued on the
Issue Date; 
 (2) (a) Indebtedness existing on the Issue Date and any guarantees thereof (including the Existing Convertible
Notes outstanding on the Issue Date but excluding Indebtedness described in clause (1) above or clause (3) below) and (b) any awards of Existing Convertible Notes granted from time to time after the Issue Date pursuant to the
Management Incentive Plan in compliance with the indenture governing the Existing Convertible Notes in an aggregate principal amount that, together with the aggregate principal amount of any then-outstanding awards of Existing Convertible Notes
granted under the Management Incentive Plan, does not exceed the maximum principal amount of Existing Convertible Notes issuable pursuant to the Management Incentive Plan as in effect on the Issue Date; 

  
 50 












 (3) the Incurrence by the Company or any Guarantor of (a) up to
$50 million of Indebtedness represented by a Cash Collateralized Credit Facility and (b) up to $50 million of Indebtedness (which may be, without limitation, First Lien Debt) pursuant to one or more Credit Facilities providing
revolving credit (including letter of credit availability) to the Company or any Guarantor for working capital or other general corporate purposes; 

(4) the Incurrence by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in exchange for, or the
net proceeds of which are used to renew, refund, refinance, replace, defease or discharge, in whole or in part, any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be Incurred under
Section 4.09(a) or clause (1) or (2) of this Section 4.09(b) or this clause (4); 

(5) the Incurrence by Company or any Restricted Subsidiary of intercompany Indebtedness between or among the Company and any of
the Restricted Subsidiaries; provided, however, that; 
 (A) if the Company or any Guarantor is the obligor on
such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of the Company, or the
applicable Guarantees, in the case of a Guarantor; and 
 (B) upon any (i) subsequent issuance or transfer of Equity
Interests or any other event that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary, or (ii) sale or other transfer of any such Indebtedness to a Person that is not the Company or a
Restricted Subsidiary, the exception provided by this clause (5) shall no longer be applicable to such Indebtedness and such Indebtedness will be deemed to have been Incurred at the time of any such issuance, sale or transfer; 

(6) the Incurrence by the Company or any Restricted Subsidiary of Hedging Obligations in the ordinary course of business and
not for speculative purposes: 
 (7) the guarantee by the Company or any Restricted Subsidiary of Indebtedness of the Company
or a Restricted Subsidiary that was permitted to be Incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes or a Guarantee, then the guarantee
shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (8) (a) the
Incurrence by the Company or any Restricted Subsidiary of Indebtedness in respect of statutory obligations, workers’ compensation claims, self-insurance obligations, surety, customs, importation or appeal bonds, performance bonds or other
Indebtedness of a like nature, in each case in the ordinary course of business and (b) surety or appeal bonds related to judgments or litigation; 

(9) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 

  
 51 












 (10) the Incurrence by the Company or any Restricted Subsidiary of
Indebtedness arising from agreements providing for indemnification, earn-outs, adjustment of purchase price or similar obligations, or guarantees or letters of credit, surety bonds or performance bonds securing any obligations of the Company or any
Restricted Subsidiary pursuant to such agreements, in each case, Incurred in connection with the acquisition or disposition of any business, assets or the Capital Stock of a Subsidiary, other than guarantees of Indebtedness Incurred by any Person
acquiring all or any portion of such business, assets or the Capital Stock of a Subsidiary for the purpose of financing such acquisition; provided, however, that, in the case of a disposition, the maximum aggregate liability in respect
of all such Indebtedness shall at no time exceed the gross proceeds (including non-cash proceeds (the Fair Market Value of such non-cash proceeds being measured at the
time received and without giving effect to any subsequent changes in value)) actually received by the Company and the Restricted Subsidiaries in connection with such disposition; 

(11) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness not otherwise permitted pursuant to
clauses (1) through (10) above or clauses (12) through (16) below in an amount, together with any other Indebtedness Incurred pursuant to this clause (11) then outstanding, not in excess of $135 million; 

(12) Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations (or any guarantee
thereof or indemnity with respect thereto), in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant, equipment or other assets (including Capital Stock) used
in the business of the Company or any Restricted Subsidiary, and Permitted Refinancing Indebtedness in respect thereof, in an amount, together with any other Indebtedness Incurred pursuant to this clause (12) and Permitted Refinancing
Indebtedness in respect thereof then outstanding, not to exceed the greater of $45 million and 4.5% of Total Assets; 

(13) the issuance of shares of Preferred Stock of a Restricted Subsidiary to the Company or another Restricted Subsidiary;
provided that any subsequent issuance or transfer of Equity Interests or any other event that results in any Restricted Subsidiary that holds such shares of Preferred Stock ceasing to be a Restricted Subsidiary or any other transfer of any
such shares of Preferred Stock (except to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of shares of Preferred Stock not permitted by this clause (13); 

(14) Indebtedness, Disqualified Stock or Preferred Stock of a joint venture to the Company or a Restricted Subsidiary and to
other holders of Equity Interests or participants of such joint venture so long as (i) the percentage of the aggregate amount of such Indebtedness, Disqualified Stock or Preferred Stock of such joint venture owed to such holders of its Equity
Interests does not exceed the percentage of the aggregate outstanding amount of the Equity Interests of such joint venture held by such holders and (ii) the amount of such Indebtedness, Disqualified Stock or Preferred Stock, together with any
other Indebtedness, Disqualified Stock and Preferred Stock Incurred or issued pursuant to this clause (14) then outstanding, does not exceed $25 million; 

(15) Indebtedness Incurred or Disqualified Stock issued by the Company or any Restricted Subsidiary or Preferred Stock issued
by any of the Restricted Subsidiaries to the extent that the net proceeds thereof are promptly deposited with the Trustee to satisfy and discharge the Notes in accordance with this Indenture; and 

(16) the Incurrence by the Company or any Guarantor of Indebtedness, and Permitted Refinancing Indebtedness in respect thereof,
in an amount, together with such Permitted Refinancing Indebtedness, not to exceed $100 million for the purpose of financing a portion of the purchase price of a 7th generation (or later) Deepwater Vessel or one or more Jackup Rigs in a single
transaction or series of related transactions so long as the Indebtedness Incurred in such transaction or series of related transactions pursuant to this clause (16) is not more than 40% of the purchase price for such Deepwater Vessel or Jackup
Rig(s). 

  
 52 












 For purposes of determining compliance with this Section 4.09, in
the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) above or could be Incurred pursuant to Section 4.09(a), the
Company or the applicable Restricted Subsidiary will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its Incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that
complies with this Section 4.09. The accrual of interest or Preferred Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional
Indebtedness with the same terms (including the payment of paid-in-kind (or “PIK”) interest with respect to the Existing Convertible Notes), the
reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional shares of the same class of Preferred Stock or Disqualified
Stock will not be deemed to be an Incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount of any such accrual, accretion or payment
(excluding the payment of paid-in-kind (or “PIK”) interest with respect to the Existing Convertible Notes) is included in Consolidated Interest Expense of the
Company as accrued. 
 The amount of any Indebtedness outstanding as of any date will be: 

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 

(A) the Fair Market Value of such assets at the date of determination; and 

(B) the amount of the Indebtedness of the other Person; and 

(4) in the case of Hedging Obligations, the termination value of the agreement or arrangement giving rise to such Hedging
Obligations that would be payable by the specified Person at such date. 
 (c) Notwithstanding anything to the contrary in this Indenture,
the Company will not, and will not permit any Guarantor to, directly or indirectly, Incur any Indebtedness (including Acquired Debt) that is contractually subordinated in right of payment to any Indebtedness of the Company or such Guarantor, as the
case may be, unless such Indebtedness is expressly subordinated in right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or
such Guarantor, as the case may be; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured
on a junior Lien basis. 
 For purposes of determining compliance with any dollar-denominated restriction on the Incurrence of Indebtedness,
the Dollar Equivalent of the principal amount of Indebtedness denominated in another currency will be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term
Indebtedness, or first committed, in the case of Indebtedness Incurred under a revolving credit facility; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a currency other than dollars, and such
refinancing would cause the applicable dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such dollar-denominated restriction will be deemed not to have been
exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 

  
 53 












 Notwithstanding any other provision of this Section 4.09, the
maximum amount of Indebtedness that the Company or the applicable Restricted Subsidiary may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 

For the avoidance of doubt, any reversal of the satisfaction and discharge of the indenture governing the Second Lien Notes or failure to
consummate the redemption of such Second Lien Notes as described in the Offering Circular shall be deemed to be an Incurrence of Indebtedness and Liens in respect of such Second Lien Notes. 

SECTION 4.10. Limitation on Asset Sales. 

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, consummate any Asset Sale unless:

 (1) the Company or the Restricted Subsidiary, as the case may be, receives consideration at the time of consummation of
such Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 

(2) at least 75% of the consideration received in such Asset Sale by the Company or such Restricted Subsidiary is in the form
of cash or Cash Equivalents; 
 provided, that the foregoing requirements shall not apply with respect to any Involuntary Transfer. 

(b) For purposes of Section 4.10(a), each of the following will be deemed to be cash: 

(1) any Indebtedness or other liabilities, as shown on the Company’s most recent consolidated balance sheet, of the
Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed, repaid or retired by the transferee of any such assets so long as the
Company or such Restricted Subsidiary is released from further liability in respect thereof; and 
 (2) any securities, notes
or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 180 days after receipt thereof, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents, to the extent
of the cash or Cash Equivalents received in that conversion; provided, however, that to the extent such securities consist of publicly-traded common equity securities of a Public Company having a world-wide market capitalization of at least
$500 million at the time of receipt by the Company or the applicable Restricted Subsidiary, such 180-day period shall be extended to 365 days (and provided, further, that a binding commitment
made within such 365-day period by the Company or the applicable Restricted Subsidiary to convert such securities into cash or Cash Equivalents shall be permitted under this clause (2) so long as
such securities are actually so converted within 545 days from the receipt thereof); and 
 (3) any Designated
Noncash Consideration received by the Company or any of the Restricted Subsidiaries from the transferee having an aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause
(3) that is at that time outstanding, not to exceed $25 million at the time of the receipt of such Designated Noncash Consideration (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time
received and without giving effect to subsequent changes in value). 

  
 54 












 (c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale (including,
without limitation, an Involuntary Transfer), the Company or the applicable Restricted Subsidiary, as the case may be, may apply such Net Proceeds at its option to any combination of the following: 

(1) (a) to purchase, repay or prepay Superpriority Debt (and, if such Superpriority Debt consists of revolving debt, to
correspondingly reduce commitments with respect thereto) or cash collateralize letters of credit in respect of Superpriority Debt or (b) to purchase, repay or prepay First Lien Debt other than Superpriority Debt; provided that, to the
extent purchases, repayments or prepayments of any First Lien Debt are made pursuant to this clause (1)(b), the Company shall equally and ratably redeem the Notes as provided in Section 3.07 or repay or offer to repay
Notes, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer to Holders in accordance with the procedures set forth in Section 3.09 and this
Section 4.10 for an Asset Sale Offer; 
 (2) to acquire all or substantially all of the assets of,
or any Capital Stock of, any Person primarily engaged in a Permitted Business, if, in the case of any such acquisition of Capital Stock, such Person is or becomes a Restricted Subsidiary as a result of such acquisition; 

(3) to make a capital expenditure that is used or useful in a Permitted Business; or 

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted
Business (including, without limitation, Collateral Vessels, related assets and any related Ready for Sea Costs) or make any deposit, installment or progress payment in respect of such assets or payment of any related Ready for Sea Costs, 

provided that (x) a binding commitment made within the 365-day period described above by
the Company or the applicable Restricted Subsidiary to apply Net Proceeds from an Asset Sale in accordance with clauses (2), (3) and/or (4) above shall satisfy the requirements of such clauses with respect to such Net Proceeds so long as such
Net Proceeds are actually so applied within 545 days from the receipt thereof from such Asset Sale and (y) if all or any portion of the assets sold or transferred in such Asset Sale constituted Collateral, in the case of any application of Net
Proceeds pursuant to clause (2), (3) or (4) above, the Company shall, or shall cause the applicable Restricted Subsidiary to, pledge any assets (including, without limitation, any acquired Capital Stock) acquired with such Net Proceeds to
secure the Notes Obligations on a first-priority secured basis (subject to the payment priority in favor of the holders of Superpriority Debt, if any, set forth in the Collateral Documents and subject to Permitted Collateral Liens) pursuant to the
Collateral Documents in accordance with this Indenture. 
 (d) Pending the final application of any Net Proceeds, the Company or the
applicable Restricted Subsidiary may apply the Net Proceeds to temporarily reduce outstanding revolving credit Indebtedness of the Company or any of the Restricted Subsidiaries, respectively, or invest the Net Proceeds in cash and Cash Equivalents.

 (e) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(c) will
constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20 million, the Company shall, within 10 Business Days thereof, make an offer (an “Asset Sale Offer”) in
accordance with Section 3.09 to all Holders and holders of any other First Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem such First
Lien Debt with the proceeds of sales of assets to purchase, prepay or redeem the Notes and such other First Lien Debt on a pro rata basis in an aggregate principal amount equal to the Excess Proceeds. The repurchase date in any Asset Sale
Offer shall be specified by the Company, which date will be no earlier than 30 days and no later than 60 days from the date the notice of such Asset Sale Offer is delivered. The offer price in any Asset Sale Offer will be equal to 100% of the
principal amount, plus accrued and unpaid interest and Additional Amounts, if any, to, but not including, the date of purchase, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest
Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company and the Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture.
If the aggregate principal amount of Notes or other First Lien Debt tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select the Notes and other First Lien Debt for purchase on a pro rata basis unless
otherwise required by law or applicable stock exchange or Depository requirements (with such adjustments as may be deemed appropriate by the Company so that only Notes and other First Lien Debt in denominations of $2,000 and integral multiples of
$1,000 in excess thereof will be outstanding after such purchase). For the purposes of calculating the principal amount of any such Indebtedness not 

  
 55 












 
denominated in U.S. dollars, such Indebtedness shall be calculated by converting any such principal amounts into their Dollar Equivalent determined as of the Business Day immediately prior to the
date on which the Asset Sale Offer is announced. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those requirements, laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or
regulations conflict with the Asset Sale provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this
Section 4.10 by virtue of such compliance. 
 (g) The provisions of this Section 4.10
with respect to the Company’s obligation to make an Asset Sale Offer as a result of an Asset Sale may be waived or modified at any time with the written consent of the Holders of a majority in aggregate principal amount of the Notes then
outstanding. 
 SECTION 4.11. Limitation on Transactions with Affiliates. 

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, make any payment to, or sell, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the
Company (each, an “Affiliate Transaction”) involving, with respect to any such transaction or series of related transactions, payments or consideration in excess of $1 million, unless: 

(1) the Affiliate Transaction is on terms that are either (a) no less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company or
(b) if, in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant
Restricted Subsidiary from a financial point of view; and 
 (2) the Company delivers to the Trustee: 

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $25 million, a resolution of the Board of Directors of the Company accompanied by an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this
Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $50 million, an opinion issued to the Board of Directors of the Company by an accounting, appraisal or investment banking firm of international standing or generally recognized in the shipping or offshore drilling industries as
qualified to perform the tasks for which such firm has been engaged as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view or that the terms of such Affiliate Transaction are no
less favorable to the Company or the relevant Restricted Subsidiary, taken as a whole, than those that could have been obtained in a comparable arm’s-length transaction by the Company or such Restricted
Subsidiary with a Person that is not an Affiliate of the Company. 

  
 56 












 For the avoidance of doubt, with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration of $25 million or less, the determination that such Affiliate Transaction or series of Affiliate Transactions complies with this Section 4.11 may be made by a
Financial Officer of the Company. 
 (b) The following items will not be deemed to be Affiliate Transactions, as applicable, and, therefore,
will not be subject to the provisions of Section 4.11(a): 
 (1) any employment agreement, employee
benefit plan, compensation plan or arrangement, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of the Restricted Subsidiaries in the ordinary course of business and payments pursuant
thereto; 
 (2) payment of reasonable directors’ fees to directors of the Company or any Restricted Subsidiary; 

(3) transactions solely between or among the Company and/or any of the Restricted Subsidiaries; 

(4) the issuance or sale of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of capital
contributions from, Affiliates of the Company; 
 (5) loans or advances to employees of the Company or any Restricted
Subsidiary in the ordinary course of business not to exceed $5 million in the aggregate at any one time outstanding; 

(6) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the
Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (7) Permitted
Investments (other than Investments permitted by clause (3) of the definition thereof) and Restricted Payments that do not violate the provisions of Section 4.07; 

(8) transactions between the Company or any of the Restricted Subsidiaries and any Person that would not otherwise constitute
an Affiliate Transaction except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of the Company or such
Restricted Subsidiary, as applicable, on any matter involving such other Person; 
 (9) any agreement as in effect on the
Issue Date or any amendments, renewals or extensions of any such agreement (so long as such amendments, renewals or extensions are not materially less favorable, taken as a whole, to the Holders); and 

(10) transactions with customers, clients, suppliers, joint venture partners or purchasers or sellers of goods or services, in
each case in the ordinary course of business of the Company and the Restricted Subsidiaries and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of the Board of Directors or management of
the Company, such transactions are on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained at the same time of such transactions in a comparable transaction by the Company or
such Restricted Subsidiary with an unrelated Person. 

  
 57 












 SECTION 4.12. Limitation on Liens. 

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist (i) any Lien of any kind on any Collateral, except for Permitted Collateral Liens, or (ii) any Lien of any kind securing Indebtedness on any of its property or assets that are not Collateral, except for Permitted Liens. 

SECTION 4.13. Additional Guarantees. 

If (i) the Company acquires or creates any Restricted Subsidiary (other than an Immaterial Subsidiary), or (ii) as of the date of
any financial statements delivered pursuant to Section 4.03, a Restricted Subsidiary that was previously an Immaterial Subsidiary has ceased to meet the definition thereof (but remains a Restricted Subsidiary), then the
Company will (1) cause such Subsidiary to, within 20 Relevant Business Days of such event, (x) execute and deliver to the Trustee a supplemental indenture substantially in the form of Annex A hereto pursuant to which such Person will
become a Guarantor and (y) execute amendments to the Collateral Documents pursuant to which it will grant a Lien on any Collateral held by it in favor of the First Lien Collateral Agent, for the benefit of the Holders, and become a Collateral
Grantor thereunder, and cause such Liens to be perfected as required thereby and (2) deliver to the Trustee and First Lien Collateral Agent one or more opinions of counsel in connection with the foregoing as specified in this Indenture. 

SECTION 4.14. Existence. 

Subject to Article 5, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its
existence. 
 SECTION 4.15. Offer to Repurchase Upon Change of Control. 

(a) If a Change of Control occurs, the Company shall make an offer (a “Change of Control Offer”) to each Holder to
repurchase all or any part (equal to a minimum amount of $2,000 and integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash (the “Change of Control Payment”) equal to 101% of
the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased to, but not including, the date of purchase (the “Change of Control Payment Date”),
subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date. No later than 30 days following any Change of Control, the Company shall deliver a notice to the Trustee and
paying agent and each Holder describing the transaction or transactions that constitute the Change of Control and stating: 

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes
properly tendered and not withdrawn pursuant to the Change of Control Offer will be accepted for payment; 
 (2) the Change
of Control Payment and the Change of Control Payment Date, which will be no earlier than 30 days and no later than 60 days from the date such notice is delivered; 

(3) that any Note not properly tendered will continue to accrue interest; 

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant
to the Change of Control Offer shall cease to accrue interest on and after the Change of Control Payment Date; 
 (5) that
Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on the reverse
of the Notes completed and such customary documents as the Company may reasonably request, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment
Date; 

  
 58 












 (6) that Holders will be entitled to withdraw their election if the Paying
Agent receives, prior to the close of business on third Business Day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a
statement that such Holder is withdrawing its election to have the Notes purchased; and 
 (7) that Holders whose Notes are
being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess
thereof. 
 The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and
any other securities laws and regulations to the extent those requirements, laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities
laws or regulations conflict with the provisions of this Section 4.15, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this
Section 4.15 by virtue of such compliance. 
 (b) On or before the Change of Control Payment Date, the Company
shall, to the extent lawful: 
 (1) accept for payment all Notes or portions thereof properly tendered and not withdrawn
pursuant to the Change of Control Offer; 
 (2) deposit with the paying agent an amount equal to the Change of Control
Payment in respect of all Notes or portions Notes properly tendered and not withdrawn; and 
 (3) deliver or cause to be
delivered to the Trustee and Paying Agent the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 

(c) The paying agent shall deliver to each Holder of Notes properly tendered and not withdrawn the Change of Control Payment for such Notes
(or, if all the Notes are then in global form, make such payment through the facilities of the Depository) and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 

(d) Notwithstanding anything to the contrary in this Section 4.15, the Company shall not be required to make a
Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control
Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer, or (2) notice of redemption of all Notes has been given pursuant to Section 3.07, unless there
is a default in payment of the applicable redemption price. 
 (e) Notwithstanding anything to the contrary contained herein, a Change of
Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 

(f) The provisions of this Section 4.15 relating to the Company’s obligation to make a Change of Control Offer,
including the definition of “Change of Control,” may be waived or modified at any time (including after a Change of Control) with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding.

 SECTION 4.16. Payments for Consent. 

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any cash
consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, any Guarantee or the Notes unless such consideration is offered to be paid and is paid
to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment. 

Notwithstanding the foregoing, the Company and the Guarantors shall be permitted, in connection with any offer or payment of consideration
for, or as an inducement to, any consent, waiver or amendment of any of the terms or provisions of this Indenture, any Guarantee or the Notes, to exclude Holders in any jurisdiction or any category of Holders where (1) the solicitation of such
consent, waiver or amendment, including in connection with any tender or exchange offer, or (2) the payment of the consideration therefor, could reasonably be interpreted as requiring the Company or any Guarantor to file a registration
statement, prospectus or similar document under any applicable securities laws or listing requirements (including, but not limited to, the U.S. federal securities laws and the laws of the European Union or any of its member states), which the
Company in its sole discretion reasonably determines (acting in good faith) (a) would be materially burdensome (it being understood that it would not be materially burdensome to file the consent documents used in other jurisdictions, any
substantially similar documents or any summary thereof with the securities or financial services authorities in such jurisdiction); or (b) such solicitation would otherwise not be permitted under applicable law in such jurisdiction or with
respect to such category of Holders. 
 SECTION 4.17. Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if: 

(1) the Company would be permitted to make (i) a Permitted Investment or (ii) an Investment pursuant to
Section 4.07, in either case, in an amount equal to the Fair Market Value of all outstanding Investments owned by the Company and the Restricted Subsidiaries in such Subsidiary at the time of such designation; 

(2) such Restricted Subsidiary meets the definition of an “Unrestricted Subsidiary”; 

(3) the designation would not constitute or cause (with or without the passage of time) a Default or Event of Default and no
Default or Event of Default would be in existence following such designation; and 
 (4) the Company delivers to the Trustee
an Officers’ Certificate giving effect to such designation. 
 If a Restricted Subsidiary is designated as an Unrestricted Subsidiary,
the aggregate Fair Market Value of all outstanding Investments owned by the Company and the Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation
and will reduce the amount available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of Permitted Investments, as determined by the Company. 

  
 60 












 (b) The Board of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary if: 
 (1) the Company and the Restricted Subsidiaries may Incur the Indebtedness
and Liens (and the Company and the Restricted Subsidiaries shall be deemed to Incur such Indebtedness and Liens upon such designation) of such Subsidiary under Sections 4.09 and 4.12; 

(2) the designation would not constitute or cause (with or without the passage of time) a Default or Event of Default and no
Default or Event of Default would be in existence following such designation; and 
 (3) the Company delivers to the Trustee
an Officers’ Certificate giving effect to such designation. 
 SECTION 4.18. Business Activities. 

The Company will not, and will not permit any of the Restricted Subsidiaries to, engage in any business other than Permitted Businesses and
ownership of Persons engaged in Permitted Businesses, except to such extent as would not be material to the Company and the Restricted Subsidiaries taken as a whole. 

SECTION 4.19. Partial Vessel Transfers. 

The Company and the Guarantors shall be permitted to transfer partial interests in a Collateral Vessel in a transaction that complies with the
terms of this Indenture, including Section 4.10 and Section 5.01 and upon completion of the following: 

(a) the Company shall give the First Lien Collateral Agent written notice of any such proposed transfer not fewer than 14 days prior to the
anticipated date of such transfer; 
 (b) any bill of sale or other instrument of partial transfer shall state on its face that the interest
transferred is subject to the Lien of the relevant Vessel Mortgage; 
 (c) the relevant Collateral Vessel will be duly re-registered in the joint names of the transferor Guarantor and the transferee showing the individual percentage interest held by each under the laws and flag of the relevant jurisdiction simultaneously with such
transfer and evidence thereof delivered to the First Lien Collateral Agent on such date; 
 (d) simultaneously with such transfer the
transferee will acknowledge in writing to the First Lien Collateral Agent that it takes its interest subject to the Vessel Mortgage; 
 (e)
on the same date of such transfer, the Company shall deliver to the First Lien Collateral Agent a certificate of ownership and encumbrance or similar certificate issued by the jurisdiction of registration of the Collateral Vessel evidencing (x) re-registration in the joint names of the transferor Guarantor and the transferee and (y) the continuance of the Vessel Mortgage in favor of the First Lien Collateral Agent; and 

(f) the Company shall cause to be delivered to the First Lien Collateral Agent on the same date of such transfer a legal opinion from outside
counsel reasonably satisfactory to the First Lien Collateral Agent to the following effect (i) the Collateral Vessel is duly registered (preliminarily registered if the jurisdiction is Panama) in the joint names of the transferor Guarantor and
the transferee with the appropriate authorities of the Collateral Vessel’s jurisdiction of registry; (ii) the Vessel Mortgage continues to constitute the legal, valid and binding obligation of the transferor Guarantor and remains duly
registered as a First Lien Vessel Mortgage in favor of the First Lien Collateral Agent with priority dating back to the date on which such First Lien Vessel Mortgage was initially registered in favor of the First Lien Collateral Agent;
(iii) all pledges of Collateral relating to the Collateral Vessel continue to constitute legal, valid and binding obligations of the transferor Guarantor; (iv) all filings and consents with respect to such transfer in the relevant
jurisdictions have been obtained or made; and (v) such transfer is in compliance with the terms of this Indenture. Such legal opinion shall be in form and substance reasonably satisfactory to the First Lien Collateral Agent. The counsel issuing
such opinion may rely on local counsel admitted to practice in the jurisdiction of registration of the Collateral Vessel with respect to matters 

  
 61 












 
governed by the laws of such jurisdiction. If the Collateral Vessel transferred is registered under the laws and flag of Panama, the Company shall also deliver to the First Lien Collateral Agent
an opinion of Panamanian counsel reasonably satisfactory to the First Lien Collateral Agent not later than five (5) months after the date of transfer confirming that such Collateral Vessel has been permanently registered in the joint names of
the transferor Guarantor and the transferee. 
 SECTION 4.20. Rights to Earnings from the Collateral Vessels. 

(a) The Company shall not permit any of the Restricted Subsidiaries (other than any Guarantor) to be the owner of a Vessel or an Internal
Charterer, or to be subject to a Contract Winning Trigger. The Company shall, or shall cause one or more of the Guarantors to, cause all Earnings paid or payable to the Company or any Guarantor under each Drilling Contract to be deposited into one
or more Earnings Accounts and at all times maintain the Earnings Accounts. Each Earnings Account shall at all times be in the name of the Company or a Guarantor and be subject to an account control agreement (or other comparable arrangement under
applicable laws) effective to perfect the first priority security interest of the First Lien Collateral Agent for the benefit of Holders (except for deposit accounts that are Excluded Property). 

(b) Notwithstanding Section 4.20(a), if the terms of a Drilling Contract or any applicable legal requirements require that any such
Earnings be paid to a non-United States bank account by the counterparty to such Drilling Contract, this Section 4.20 shall not be deemed violated if funds standing to the credit of
such account are transferred as soon as reasonably practicable after deposit thereof in the jurisdiction in which the account is located to an account that qualifies as an Earnings Account. 

SECTION 4.21. Reflagging. 
 (a)
The Company shall not and shall not permit any Guarantor to change the state of registration of a Collateral Vessel from its state of registration as of the Issue Date (or as of the date it becomes a Collateral Vessel, if later) to any other
jurisdiction; provided that the state of registration of any Collateral Vessel may be changed to an Approved Flag State if: 

(1) a replacement mortgage and, if applicable, deed of covenants is entered into by the applicable Guarantor; 

(2) the replacement mortgage is registered with the new state of registration; and 

(3) an opinion of counsel selected by the Board of Directors of the Company, acting in good faith, is provided to the First
Lien Collateral Agent confirming the enforceability of the replacement mortgage and its due registration, in each case, as soon as reasonably practicable following the release of the mortgage over the applicable Collateral Vessel. 

The First Lien Collateral Agent shall, at the cost of the Company, release the mortgage and other applicable security over the applicable
Collateral Vessel, and take such other steps as may be reasonably required in connection with a change of the state of registration of a Collateral Vessel provided that the Company and the Guarantors provide the documents listed above as soon as
reasonably practicable upon the release of the mortgage and other applicable security over the applicable Collateral Vessel. 
 SECTION
4.22. Payment of Additional Amounts. 
 (a) All payments made by or on behalf of the Company or any Guarantor under or with respect to the
Notes or the Guarantees will be made free and clear of and without withholding or deduction for, or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge of whatever nature (including penalties,
additions to tax, interest and other liabilities related thereto) (hereinafter “Taxes”) unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any
Taxes imposed or levied by or on behalf of the government of the Cayman Islands or any political subdivision or any authority or agency therein or thereof having power to tax, or any other jurisdiction in which the


  
 62 












 
Company or any Guarantor (including any successor entity) is organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes, or any jurisdiction
from or through which payment is made (each a “Specified Tax Jurisdiction” and such Taxes, “Indemnified Taxes”), will at any time be required to be made from any payments made under or with respect to
the Notes or the Guarantees, the Company, the relevant Guarantor or other payor, as applicable, will pay such additional amounts (the “Additional Amounts”) as may be necessary so that the net amount received in respect of
such payments by each Holder after such withholding or deduction (including any withholding or deduction from Additional Amounts) will not be less than the amount such Holder would have received if such Indemnified Taxes had not been withheld or
deducted; provided, however, that Indemnified Taxes do not include: 
 (1) any Taxes to the extent such
Taxes would not have been so imposed but for the Holder (or a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership, or a corporation) having any present or former connection with
the Specified Tax Jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or
present therein or having, or having had, a permanent establishment therein (other than the mere acquisition, ownership, holding, enforcement, exercise of rights or receipt of payment in respect of the Notes or the Guarantees); 

(2) any estate, inheritance, gift, sales, excise, transfer, capital gains, personal property Tax or similar Taxes; 

(3) any Taxes to the extent such Taxes are imposed as a result of the failure of the Holder or beneficial owner of the Notes to
complete, execute and deliver to the Company or the relevant Guarantor, as applicable, any form or document that such Holder or beneficial owner is legally entitled to complete, execute, and deliver, that may be required by law or by reason of
administration of such law and that is reasonably requested in writing to be delivered to the Company or the relevant Guarantor in order to enable the Company or the relevant Guarantor to make payments on the Notes without deduction or withholding
for Taxes, or with deduction or withholding of a lesser amount, which form or document will be delivered within 60 days of a written request therefor by the Company or the relevant Guarantor; 

(4) any Taxes to the extent such Taxes would not have been so imposed but for the beneficiary of the payment having presented a
Note for payment (in cases in which presentation is required) more than 30 days after the date on which such payment or such Note became due and payable or the date on which payment thereof is duly provided for, whichever is later (except to the
extent that the Holder would have been entitled to Additional Amounts had the Note been presented on the last day of such 30-day period); 

(5) [Reserved]; 

(6) any Taxes to the extent such Taxes are imposed on a Note presented for payment by or on behalf of a Holder or beneficial
owner who would have been able to avoid such Tax by presenting the relevant Note to another Paying Agent in a member state of the European Union; 

(7) any Taxes to the extent such Taxes are payable other than by deduction or withholding at source; 

(8) Taxes imposed pursuant to sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the
“Code”), any regulations thereunder or official interpretations thereof, any intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any fiscal or regulatory
legislation, rules or practices implementing such an intergovernmental agreement), or any agreement entered into pursuant to section 1471(b)(1) of the Code; or 

  
 63 












 (9) any combination of items (1) through (8) above. 

(b) If the Company or any Guarantor, as applicable, becomes obligated to pay Additional Amounts with respect to any payment under or with
respect to the Notes or the Guarantees, the Company or the relevant Guarantor, as applicable, will deliver to the Trustee and Paying Agent at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises
after the 30th day prior to that payment date, in which case the Company or the relevant Guarantor, as applicable, will deliver to the Trustee and Paying Agent promptly thereafter but in no event later than five Business Days prior to the date of
payment) an Officers’ Certificate stating the fact that Additional Amounts will be payable and the amount so payable. The Officers’ Certificate must also set forth any other information necessary to enable the Paying Agent to pay
Additional Amounts to Holders on the relevant payment date. The Trustee and Paying Agent will be entitled to rely solely on such Officers’ Certificate as conclusive proof as to the amount of such payments and that such payments are necessary.
The Company or the relevant Guarantor, as applicable, will provide the Trustee and Paying Agent with documentation reasonably satisfactory to the Trustee and Paying Agent evidencing the payment of Additional Amounts. 

(c) The Company or the relevant Guarantor or applicable withholding agent, as applicable, will make all withholdings and deductions required
by law and will remit the full amount deducted or withheld to the relevant governmental authority on a timely basis in accordance with applicable law. As soon as practicable, the Company or the relevant Guarantor or applicable withholding agent, as
applicable, will provide the Trustee and Paying Agent with an official receipt or, if official receipts are not obtainable, other documentation reasonably satisfactory to the Trustee and Paying Agent evidencing the payment of the Taxes so withheld
or deducted. Upon request, copies of those receipts or other documentation, as the case may be, will be made available by the Company to the Holders. 

(d) Whenever in this Indenture or the Notes there is referenced, in any context, the payment of amounts based upon the principal amount of the
Notes or of principal, interest or any other amount payable under, or with respect to, the Notes or the Guarantees, such reference will be deemed to include payment of Additional Amounts as described in this Section 4.22 to
the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. For the avoidance of doubt, with respect to Notes represented by a Global Note, a Holder with respect to Additional Amounts and the related
provisions of this Indenture shall be deemed to include a Holder representing the interests of a beneficial owner of the Notes or acting on behalf of a beneficial owner of the Notes. 

(e) The Company or the relevant Guarantor, as applicable, will pay any present or future stamp, issue, registration, value added, court or
documentary taxes or any other excise or property taxes, charges or similar levies (including penalties, additional amounts, interest and any other liabilities and reasonable expenses related thereto) that arise in any Specified Tax Jurisdiction
from the execution, delivery, enforcement or registration of the Notes, the Guarantees, this Indenture or any other document or instrument in relation thereof, or the receipt of any payments with respect to the Notes or the Guarantees, and the
Company or the relevant Guarantor, as applicable. 
 (f) The obligations of the Company and the Guarantors under this
Section 4.22 will survive any termination, defeasance or discharge of this Indenture and any transfer by a Holder of its Notes, and will apply mutatis mutandis to any jurisdiction in which any successor person to the
Company or any Guarantor is organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes or any jurisdiction from or through which payment is made or any political subdivision or authority or agency
thereof or therein. 
 SECTION 4.23. Suspended Covenants. 

(a) During any period of time (1) the Notes have an Investment Grade Rating and (2) no Default or Event of Default has occurred and
is continuing under this Indenture, the Company and the Restricted Subsidiaries will not be subject to the provisions of Sections 3.08, 4.07, 4.08, 4.09, 4.10, 4.11 and 5.01(a)(4) of this Indenture
(collectively, the “Suspended Covenants”). 

  
 64 












 (b) In the event that the Company and the Restricted Subsidiaries are not subject to the
Suspended Covenants for any period of time as a result of Section 4.23(a) and, subsequently, Moody’s or S&P withdraws its rating or downgrades the rating assigned to the Notes so that the Notes do not have an
Investment Grade Rating, or an Event of Default (other than with respect to the Suspended Covenants) occurs and is continuing (the “Reversion Date”), then the Company and the Restricted Subsidiaries shall, on and after the Reversion
Date, be subject to the Suspended Covenants. The period of time between the date the Suspended Covenants become suspended and the Reversion Date is referred to herein as the “Suspension Period.” During the
Suspension Period, the Board of Directors of the Company may not designate any of the Restricted Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.17. Notwithstanding that the Suspended Covenants may be
reinstated, no Default, Event of Default or breach of any kind under this Indenture or the Notes will be deemed to have occurred as a result of a failure of the Company and the Restricted Subsidiaries to comply with a Suspended Covenant during the
Suspension Period. 
 (c) Calculations made on and after the Reversion Date of the amount available to be made as Restricted Payments under
Section 4.07 will be made as if Section 4.07 had been in effect at all times since the Issue Date, but not during the Suspension Period, and no Default or Event of Default will be deemed to have
occurred solely by reason of a Restricted Payment made during the Suspension Period. On the Reversion Date, all Indebtedness Incurred during the continuance of the Suspension Period will be classified as having been incurred pursuant to clause
(2)(a) of Section 4.09(b). 
 (d) The Company shall provide the Trustee and Holders with prompt written notice of
any event or events giving rise to a Suspension Period or a Reversion Date, the date thereof and identifying the Suspended Covenants. The Trustee shall have no duty to monitor the ratings of the Notes or the occurrence of a Suspension Period or a
Reversion Date, or to notify Holders of the same. 
 (e) Notwithstanding that the Suspended Covenants may be reinstated, without causing a
Default or Event of Default, following a Reversion Date the Company and the Restricted Subsidiaries shall be permitted to honor any contractual commitments entered into during the Suspension Period ; provided that such contractual commitments
were entered into during the Suspension Period and not in contemplation of a reversion of the Suspended Covenants. 
 SECTION 4.24.
[Reserved]. 
 SECTION 4.25. Maintenance of Property. 

The Company will, and will cause each of the Restricted Subsidiaries to, (i) keep all material property necessary to the business of the
Company and the Restricted Subsidiaries in good working order and condition (ordinary wear and tear and loss or damage by casualty or condemnation excepted) with such exceptions as would not reasonably be expected to have a material adverse effect
on the operations, business, properties or financial condition of the Company and the Restricted Subsidiaries, taken as a whole, and (ii) furnish to the First Lien Collateral Agent, at the written request of the First Lien Collateral Agent, a
complete description of the material terms of insurance carried on the Collateral Vessels. 
 SECTION 4.26. Further Assurances. 

The Company shall, and shall cause each other Collateral Grantor to, at the Company’s sole cost and expense: 

(a) at the request of the First Lien Collateral Agent (acting at the direction of the Holders of a majority in aggregate
principal amount of the Notes then outstanding), execute and deliver all such agreements and instruments and take all further action as may be reasonably necessary or desirable (i) to describe more fully or accurately the property intended to
be Collateral or the obligations intended to be secured by any Collateral Document and/or (ii) to continue and maintain the First Lien Collateral Agent’s first-priority perfected security interest in the Collateral (subject to payment
priority in favor of holders of Superpriority Debt, if any, set forth in the Collateral Documents and subject to Permitted Collateral Liens); and 

  
 65 












 (b) at the request of the First Lien Collateral Agent (acting at the
direction of Holders of a majority in aggregate principal amount of the Notes then outstanding), file any such notice filings or other agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens
created by the Collateral Documents. 
 SECTION 4.27. Limitation on Certain Agreements. 

The Company shall not permit any Collateral Grantor to enter into any agreement that requires the proceeds received from any sale of
Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than (i) the Notes, (ii) any other First Lien Obligations (so long as the Notes are required to be repaid, redeemed,
defeased, acquired or retired on a ratable basis with such other First Lien Obligations), (iii) the Existing Convertible Notes or (iv) otherwise as may be permitted or required by this Indenture or the Collateral Documents, including with
respect to any Permitted Collateral Liens; provided that any such agreement may be entered into to the extent it permits such proceeds to be applied to First Lien Obligations (including the Notes) prior to or instead of such other
Indebtedness.

For purposes of the foregoing, (i) entry by the Company or any Subsidiary of the Company into one or more Drilling Contracts or other
charters, pool agreements or drilling contracts with respect to any Vessels entered into in the ordinary course of business will be deemed not to constitute a sale, assignment, transfer, conveyance or other disposition subject to this

(b) The Company shall not permit any Guarantor to, directly or indirectly, amalgamate, consolidate or merge with or into (whether or not such

Collateral Agent on any Collateral owned by or transferred to the Successor Guarantor and delivers an Opinion of Counsel as to the enforceability thereof and such other matters as the Trustee may reasonably request; 

(E) any Collateral owned by or transferred to the Successor Guarantor shall (a) continue to constitute Collateral under

“Guarantor” shall refer instead to the Successor Company or Successor Guarantor and not to the Company or such Guarantor, respectively), and may exercise every right and power of, the Company or the Guarantor under this Indenture with the
same effect as if the Successor Company or Successor Guarantor had been named as the Company or a Guarantor in this Indenture, and thereafter, the Company or such Guarantor will be relieved of all obligations and covenants under this Indenture, the

SECTION 6.01. Events of Default. 

Each of the following is an “Event of Default”: 

(a) default in any payment of interest or any Additional Amounts with respect to the Notes when due, which default continues
for 30 days; 
 (b) default in the payment when due (at maturity, upon optional redemption, upon declaration of acceleration
or otherwise) of the principal of, or premium, if any, on, the Notes or failure by the Company to redeem or repurchase the Notes when required pursuant to this Indenture or the Notes; 

(c) failure by the Company or any Guarantor to comply with Section 5.01; 

(d) (1) except with respect to Section 4.03, failure by the Company or any of the Restricted
Subsidiaries for 30 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any


  
 68 












 
covenant or agreement (other than a default referred to in clauses (a), (b) and (c) above) contained in this Indenture, the Collateral Documents or the Notes, or (2) failure by the
Company for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with Section 4.03; 

(e) a default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced
any Indebtedness for money borrowed by the Company or any of the Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of the Restricted Subsidiaries), whether such Indebtedness or guarantee now exists or is created
after the Issue Date, if that default: 
 (1) is caused by a failure to pay principal of, or interest or premium, if any, on,
such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 

(2) results in the acceleration of such Indebtedness prior to its Stated Maturity, 

and, in either case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under
which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $30 million or more; provided, however, that if any such default is cured or waived or any such acceleration rescinded, or such
Indebtedness is repaid, within a period of 60 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the
Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
 (f) so
long as any Existing Convertible Notes are outstanding, entry by a court or courts of competent jurisdiction of a final judgment or government fine or penalty (whether by agreement, consent decree or otherwise), against the Company, any Guarantor or
any affiliate of the Company (other than Vantage Drilling Company), or entry by the Company, any Guarantor or any affiliate of the Company (other than Vantage Drilling Company) into any settlement agreement, consent decree or similar agreement with
respect to any investigations involving, or claims against, such entity, that would individually or in the aggregate exceed $50 million and (b) from and after such time as no Existing Convertible Notes are outstanding, failure by the
Company or any of the Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50 million, which judgments are not paid, discharged or stayed for a period
of 60 days and, in the event such judgments are covered by insurance (and the applicable insurance provider has been notified of such judgments and has not denied coverage), an enforcement action proceeding has been commenced by any
creditor upon such judgment or decree which is not promptly stayed; 
 (g) (1) the Collateral Documents shall for any reason
cease to create a valid and perfected first-priority Lien (subject to payment priority in favor of holders of Superpriority Debt pursuant to the terms of the Collateral Documents and subject to Permitted Collateral Liens) on any portion of the
Collateral having a Fair Market Value in excess of $25 million (in each case, other than in accordance with the terms of this Indenture, the Intercreditor Agreement or the terms of the Collateral Documents) or (2) the Company or any
Restricted Subsidiary asserts in writing that any Lien created under the Collateral Documents is invalid or unenforceable; 

(h) except as permitted by this Indenture or any Guarantee, any Guarantee of a Significant Subsidiary is held in any judicial
proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor that is a Significant Subsidiary, or any Person duly acting on behalf of any such Guarantor, denies or disaffirms its obligations
under its Guarantee; 

  
 69 












 (i) the Company, any Restricted Subsidiary that is a Significant Subsidiary
or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law:

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

(5) admits in writing it generally is not paying its debts as they become due; or 

(j) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in an involuntary case; 
 (2) appoints a
Custodian (x) of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, or (y) for all or substantially all of the
property of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary; 

(3) orders the liquidation of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary; or 
 (4) and the order or decree
remains unstayed and in effect for 60 consecutive days. 
 SECTION 6.02. Acceleration. 

Subject to the succeeding sentence, if any Event of Default occurs and is continuing, the Trustee, by written notice to the Company, or the
Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by written notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the preceding sentence, if an Event
of Default specified in clause (i) or (j) of Section 6.01 occurs, all outstanding Notes shall become due and payable immediately without further action or notice. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders
of all of the Notes, rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except with respect to nonpayment of principal, interest, premium or Additional
Amounts, if any, that have become due solely because of the acceleration) have been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereon. 

SECTION 6.03. Other Remedies. 

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of and
interest, premium, if any, and Additional Amounts, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law. 

  
 70 












 SECTION 6.04. Waiver of Past Defaults. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders
of all of the Notes, waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of principal of, premium, if any, interest, if any, or Additional Amounts,
if any, on, the Notes (other than a Payment Default or payment Event of Default that resulted from an acceleration that has been rescinded). 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, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

SECTION 6.05. Control by Majority. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes will have the right to direct the time, method and place
of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee
determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in any financial or personal liability. In case an Event of Default has occurred and is continuing, prior to taking any action hereunder,
the Trustee and First Lien Collateral Agent shall be entitled to indemnification or security (or both) satisfactory to the Trustee and First Lien Collateral Agent, respectively, against all loss, liability and expenses caused by the taking or not
taking of such action. 
 SECTION 6.06. Limitation on Suits. 

Except to enforce the right to receive payment of principal, premium, if any, or interest or Additional Amounts, if any, when due, pursuant to
Section 6.07, no Holder may pursue any remedy with respect to this Indenture or the Notes unless: 

(a) such Holder has previously given the Trustee written notice that an Event of Default is continuing; 

(b) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have made a written request to the
Trustee to pursue the remedy; 
 (c) such Holders have offered the Trustee, and the Trustee has received (if requested),
security or indemnity (or both) satisfactory to the Trustee against any loss, liability or expense; 
 (d) the Trustee has
not complied with such request within 60 days after its receipt of the request and the offer of security or indemnity (or both) satisfactory to it; and 

(e) Holders of a majority in aggregate principal amount of the then outstanding Notes have not given the Trustee a direction
inconsistent with such request within such 60-day period. 
 A Holder may not use this Indenture to prejudice the
rights of another Holder or to obtain a preference or priority over another Holder. 
 SECTION 6.07. Rights of Holders of Notes to Receive
Payment. 
 Notwithstanding any other provision of this Indenture, the rights of any Holder to receive payment of principal of, premium, if
any, interest, if any, or Additional Amounts, if any, on, the Notes, on or after the respective due dates expressed in the Notes (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the consent of such Holder. 

  
 71 












 SECTION 6.08. Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express trust against the Company and the Guarantors for the whole amount of principal of, interest, premium, if any, and Additional Amounts, if any, remaining unpaid on the Notes
and interest on overdue principal and, to the extent lawful, interest and Additional Amounts, if any, and 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. 
 SECTION 6.09. Trustee is Authorized to File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee and First Lien Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, First Lien Collateral Agent, and each of their agents and counsel) and the Holders of
the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or
deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments 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 and First Lien Collateral Agent any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee and First
Lien Collateral Agent under Section 7.06. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, First Lien Collateral Agent, and each of their agents and counsel, and
any other amounts due the Trustee and First Lien Collateral Agent under Section 7.06 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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 Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 6.10. Priorities. 

If the Trustee collects any money pursuant to this Article 6, subject to the Intercreditor Agreement and the Collateral Agency Agreement, it
shall pay out the money in the following order: 
 (a) First: to the Trustee and its agents and attorneys for amounts
due under Section 7.06, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and costs and expenses of collection incurred by the Trustee; 

(b) Second: to the Holders for amounts due and unpaid on the Notes for principal, premium, if any, interest, if any, and
Additional Amounts, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, interest, if any, and Additional Amounts, if any, respectively; and 

(c) Third: to the Company or to such other Person as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this
Section 6.10. 

  
 72 












 SECTION 6.11. Undertaking for Costs. 

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 or omitted
by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes. 

SECTION 6.12. The First Lien Collateral Agent. 

Whenever in the exercise of any remedy available to the Trustee or the exercise of any trust or power conferred on it with respect to the
Notes, the Trustee may also direct the First Lien Collateral Agent in the exercise of any of the rights and remedies available to the First Lien Collateral Agent pursuant to the Collateral Documents. 

ARTICLE 7 
 TRUSTEE 

SECTION 7.01. Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) Except during the continuance of an Event of Default:

Trustee; and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the

determine whether or not they conform to the requirements of this Indenture. 
 (c) The Trustee may not be relieved from liabilities for its
own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (i) this clause
(c) does not limit the effect of clause (b) of this Section 7.01;

shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.05. 
 (d) Whether or not therein expressly so provided, every

agreement executed in connection with this Indenture to which the Trustee or First Lien Collateral Agent is a party. 
 SECTION 7.02. Rights

 (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by
the proper Person. The Trustee need not investigate any fact or matter stated in the document.

it hereunder in good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and shall not be responsible
for the misconduct or negligence of any agent appointed by it with due care. 
 (d) The Trustee shall not be liable for any action it takes
or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture; provided that the Trustee’s conduct does not constitute willful misconduct or gross negligence.

signed by an Officer of the Company. 
 (f) If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to

any loss, liability or expense that might be incurred by it in compliance with such request or direction.

Event of Default of which a Responsible Officer of the Trustee shall have received written notification or obtained actual knowledge.

or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of
the form of action. 

  
 74 












 (j) The Trustee may request that the Company deliver an Officers’ Certificate setting
forth the names of individuals and titles of officers authorized at such times to take specified actions pursuant to this Indenture. 

SECTION 7.03. Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, any
Guarantor or any of their Affiliates with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the Trust Indenture Act of 1939, amended), it must eliminate that
conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.09. 

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, the Notes or any other
Note Document, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use
or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or
pursuant to this Indenture other than its certificate of authentication. 
 SECTION 7.05. Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if, in accordance with Section 7.02(g), the Trustee
has knowledge thereof, the Trustee shall deliver to the Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or interest, premium, or
Additional Amounts, if any, on, any Note, the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders. 

SECTION 7.06. Compensation and Indemnity. 

The Company shall pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee may agree in writing for
the Trustee’s acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request
for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and
counsel. 
 The Company and the Guarantors shall indemnify the Trustee, jointly and severally, against any and all losses, liabilities,
damages, claims or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses (including, without limitation, fees and expenses of counsel) of
enforcing this Indenture against the Company and the Guarantors (including this Section 7.06) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or any other Person) or
liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability, damage, claim or expense may be attributable to its gross negligence or willful misconduct. The Trustee
shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company and the Guarantors shall not relieve the Company or the Guarantors of their obligations hereunder. The
Company and the Guarantors shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company and the Guarantors shall pay the reasonable fees and expenses of such counsel. Neither the
Company nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 

  
 75 












 The obligations of the Company and the Guarantors under this
Section 7.06 shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 

To secure the Company’s and the Guarantors’ payment obligations in this Section 7.06, the Trustee shall
have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, and interest or Additional Amounts, if any, on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 
 When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 6.01(i) or 6.01(j) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to
constitute expenses of administration under any Bankruptcy Law. 
 The immunities, protections and exculpations available to the Trustee
under this Indenture shall also be available to the First Lien Collateral Agent and each other Agent, and the Company’s and each Guarantor’s obligations under this Section 7.06 to compensate and indemnify the
Trustee shall extend likewise to the First Lien Collateral Agent and each other Agent. 
 SECTION 7.07. Replacement of Trustee. 

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.07. 
 The Trustee may resign in writing upon thirty
(30) days’ notice at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the
Trustee and the Company in writing and may appoint a successor trustee with the consent of the Company. The Company may remove the Trustee if: 

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

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (c) a receiver, Custodian or public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Company. 
 If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or the Holders of at least 10% of the aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor Trustee. 

If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with
Section 7.09, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of 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 the
Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in
Section 7.06. Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Company’s and the Guarantors’ obligations under Section 7.06 shall
continue for the benefit of the retiring Trustee. 

  
 76 












 SECTION 7.08. Successor Trustee by Merger, etc. 

If the Trustee consolidates with, or merges or converts into, or transfers or sells all or substantially all of its corporate trust business
or assets to, another corporation or banking association, the successor corporation or banking association without any further act shall be the successor Trustee. As soon as practicable, the successor Trustee shall mail a notice of its succession to
the Company and the Holders. 
 SECTION 7.09. Eligibility; Disqualification. 

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least
$100 million as set forth in its most recent published annual report of condition. No obligor upon the Notes shall serve as a Trustee.

Guarantees and this Indenture, and the Company and the other Collateral Grantors shall be deemed to have satisfied all of their obligations under the Collateral Documents, to the extent related to the Notes and the Guarantees (and the Trustee, on
demand of and at the expense of the Company, shall execute such instruments reasonably requested by the Company acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

Upon the Company’s exercise under Section 8.01 of the option applicable to this
Section 8.03, the Company and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04, be released from their respective obligations under the
covenants contained in Article 4 (other than those in Sections 4.01, 4.02, 4.04, 4.06, 4.14, and 4.22) and in Article 11 and under all Collateral Documents, to the extent related to the Notes
and the Guarantees, to which it is a party on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed
not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all
other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Guarantees, the Company and any
Guarantor may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by
reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as
specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this
Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, Sections 6.01(d)(2) through 6.01(h) shall not constitute Events of Default. 

SECTION 8.04. Conditions to Legal or Covenant Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance: 

(a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, in the opinion of a
nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, and premium, if any, and interest and Additional Amounts, if any, on, the outstanding Notes on the stated date for payment
thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date; 

(b) in the case of an election under Section 8.02, the Company shall have delivered to the Trustee, the Registrar
and the Paying Agent an Opinion of Counsel confirming that: 
 (1) the Company has received from, or there has been published
by, the Internal Revenue Service a ruling; or 
 (2) since the Issue Date, there has been a change in the applicable U.S.
federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding
Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been
the case if such Legal Defeasance had not occurred; 

  
 78 












 (c) in the case of an election under Section 8.03, the Company
shall have delivered to the Trustee, the Registrar and the Paying Agent an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such
Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default
resulting from, or otherwise in connection with, the borrowing of funds to be applied to such deposit pursuant to this Section 8.04 (and any similar concurrent deposit relating to other Indebtedness) or the grant of any
Lien securing such borrowing); 
 (e) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or
constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of the Restricted Subsidiaries is a party or by which the Company or any of the Restricted Subsidiaries is bound; 

(f) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders over the other creditors of the Company or any Guarantor with the intent of defeating, hindering, delaying or defrauding any creditors of the Company, any Guarantor or others; and 

(g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 SECTION 8.05. Deposited Money and
Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06, all money
and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.04 or 8.08 in respect of the outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or any of its Subsidiaries acting as Paying Agent) as
the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, interest, premium, if any, and Additional Amounts, if any, but such money need not be segregated from other funds except to
the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed
against the cash or non-callable Government Securities deposited pursuant to Section 8.04 or 8.08 or the principal and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
 Anything in this Article 8 to
the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the written request of the Company any money or non-callable Government Securities held by it as provided in
Section 8.04 or 8.08 which, in the opinion of a nationally recognized investment banking, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee
(which may be the opinion delivered under Section 8.04(a)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance, Covenant Defeasance or Discharge, as the
case may be. 
 SECTION 8.06. Repayment to the Company. 

Subject to applicable escheat and abandoned property laws, any money or non-callable Government
Securities deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or interest, premium, if any, or Additional Amounts, if any, on, any Note and remaining unclaimed for two years
after such principal, interest, premium, if any, or Additional Amounts, if any, has 

  
 79 












 
become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter be
permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or non-callable Government Securities, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the written request and expense of the Company cause to be
published once, in the New York Times or The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 SECTION 8.07.
Reinstatement. 
 If the Trustee or the Paying Agent is unable to apply any money or non-callable
Government Securities 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 and
the Guarantors’ obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or the Paying
Agent is permitted to apply all such money in accordance with Section 8.05; provided, however, that, if the Company or any Guarantor makes any payment of principal of, interest, premium, if any, or
Additional Amounts, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as applicable, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or
Government Securities deposited with or held by the Trustee or the Paying Agent. 
 SECTION 8.08. Discharge. 

This Indenture, the Guarantees and, to the extent related to the Notes and the Guarantees, all Collateral Documents shall be discharged and
shall cease to be of further effect as to all Notes issued hereunder (except as to (x) the rights of Holders of outstanding Notes to receive solely from the trust fund described in clause (1)(b) of this Section 8.08,
and as more fully set forth in such clause (1)(b), payments in respect of the principal of and interest, premium, if any, and Additional Amounts, if any, on, such Notes when such payments are due, (y) the Company’s obligations with respect
to such Notes under Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.10 and 4.02 and the Appendix and (z) the rights of the Trustee and each Agent under Section 7.06 and the
Company’s obligations in connection therewith), and the Trustee, at the expense of the Company, shall execute such instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture with respect to all
the Notes, when: 
 (1) either: 

(a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes
for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and
payable within one year by reason of the mailing of a notice of redemption or otherwise and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Paying Agent as trust funds in trust solely for the benefit of the
Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be
sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation of principal, premium and Additional Amounts, if any, and accrued interest, if
any, on the Notes to the date of maturity or redemption; 

  
 80 












 (2) in respect of clause (1)(b) of this
Section 8.08, the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound
(other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to such other instrument, and in each case the granting
of Liens to secure such borrowings); 
 (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it
under this Indenture; 
 (4) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money
toward the payment of the Notes at maturity or on the redemption date, as the case may be; and 
 (5) the Company has
delivered (a) an Officers’ Certificate to the Trustee stating that all conditions precedent to satisfaction and discharge of this Indenture (“Discharge”) have been satisfied and (b) an Opinion of Counsel to the
Trustee stating that all conditions precedent to Discharge have been satisfied. 
 ARTICLE 9 

AMENDMENT, SUPPLEMENT AND WAIVER 

SECTION 9.01. Without Consent of Holders of Notes. 

Notwithstanding the provisions of Section 9.02, without the consent of any Holder, the Company, the Guarantors, the
Trustee and, if any amendment relates to any Collateral Document, the First Lien Collateral Agent, may amend or supplement this Indenture, the Notes, the Guarantees and the Collateral Documents in the following circumstances: 

(a) to cure any ambiguity, defect or inconsistency; 

(b) to provide for uncertificated Notes in addition to or in place of certificated Notes;

the legal rights under this Indenture of any such Holder in any material respect; 
 (e) to conform the text of this
Indenture, the Notes, the Guarantees or the Collateral Documents to any provision of the “Description of Notes” in the Offering Circular to the extent that such provision in such “Description of Notes” was intended to set forth,
verbatim or in substance, a provision of this Indenture, the Notes, the Guarantees or the Collateral Documents, which intent may be evidenced by an Officers’ Certificate to that effect; 

(f) to evidence and provide for the acceptance of the appointment under this Indenture and the Collateral Documents of a
successor Trustee or First Lien Collateral Agent; 
 (g) to enter into additional or supplemental Collateral Documents and to
add additional assets as Collateral to secure the Notes and the Guarantees; 
 (h) to release Collateral or any Guarantee
when permitted or required by this Indenture, the other Collateral Documents, or to amend or supplement any Collateral Document in accordance its terms; 

  
 81 












 (i) to allow any Guarantor to execute a supplemental indenture and/or a
Guarantee with respect to the Notes and to add any additional Guarantor; 
 (j) to provide for the issuance of Additional
Notes in accordance with the limitations set forth in this Indenture; 
 (k) to enter into any and all Collateral Documents
and the transactions contemplated thereby respecting the registration and mortgaging of the Collateral Vessels and to perfect the security interests and Liens granted therein; 

(l) to accept and consent to, and to take, any and all steps to perfect a security interest in any of the Collateral Vessels
and other Collateral granted pursuant to the Collateral Documents; 
 (m) to comply with requirements of the Trust Indenture
Act of 1939, as amended, if applicable, or any securities exchange on which the Notes are listed for trading or quotation; or 

(n) to make any other provisions with respect to questions arising under this Indenture, the Collateral Documents, the Notes or
the Guarantees, provided that the actions pursuant to this clause will not adversely affect the interests of the Holders in any material respect, as determined in good faith by the Company. 

In addition, the Intercreditor Agreement and the Collateral Agency Agreement, if any, may be amended in accordance with their terms and
without the consent of any Holder or the Trustee with the consent of the parties thereto or otherwise in accordance with their terms, including to add additional Indebtedness as First Lien Obligations or Junior Lien Obligations and to add as parties
thereto persons holding such Indebtedness (or any authorized agent thereof or trustee therefor) and to establish that the Liens on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral securing the First Lien
Obligations or Junior Lien Obligations, as applicable, then outstanding, in each case to the extent permitted by the First Lien Documents. 

Upon the request of the Company, and upon receipt by the Trustee of the documents described in Section 9.06, the
Trustee shall join with the Company and the Guarantors in the execution of any amendment or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be
therein contained, but the Trustee and the First Lien Collateral Agent shall not be obligated to enter into any such amendment or supplemental indenture that affects the Trustee and/or First Lien Collateral Agent’s own rights, duties or
immunities under this Indenture or otherwise. 
 SECTION 9.02. With Consent of Holders of Notes. 

Except as provided above in Section 9.01 and below in this Section 9.02, the Company, the
Guarantors, the Trustee and the First Lien Collateral Agent may amend or supplement this Indenture, the Notes and the Collateral Documents by the execution of a supplemental indenture or, in the case of any amendment or supplement to the Collateral
Documents, by the execution of an appropriate amendment or supplement thereto, with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to Sections 6.04 and 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Guarantees
or any Collateral Document may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or
exchange offer for, Notes), in each case in addition to any required consent of holders of other First Lien Obligations that may be required with respect to an amendment of or waiver under a Collateral Document. However, without the consent of each
Holder of an outstanding Note affected thereby, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder): 

(a) reduce the percentage of principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 

  
 82 












 (b) reduce the principal of, or change the fixed maturity of, any Note or
alter the premium payable upon any redemption or repurchase of the Notes pursuant to Sections 3.08, 3.09, 4.10 and 4.15; 

(c) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 

(d) waive a Default or Event of Default in the payment of principal of, or premium, if any, interest, if any, or Additional
Amounts, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the Payment Default that resulted from such
acceleration); 
 (e) make any Note payable in money other than that stated in the Notes; 

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes; 
 (g)
waive a redemption or repurchase payment with respect to any Note (other than a payment required by Section 3.08, 3.09, 4.10 or 4.15); 

(h) release any Guarantor from any of its obligations under its Guarantee or this Indenture, except in accordance with the
terms of this Indenture; 
 (i) subordinate the Notes or the Guarantees in right of payment to any other Indebtedness; or

 (j) make any change in the preceding amendment, supplement and waiver provisions. 

In addition, except as otherwise provided in this Indenture or any Collateral Document, the consent of Holders of at least two-thirds in aggregate principal amount of the then outstanding Notes will be required to release Liens for the benefit of the Holders on all or substantially all of the Collateral, other than in accordance with
this Indenture, the Intercreditor Agreement and the other Collateral Documents. 
 Upon the request of the Company and upon the receipt by
the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall join with the Company and the
Guarantors in the execution of such amendment, supplement or waiver, unless such amendment, supplement or waiver affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such amendment, supplemental indenture or waiver. 
 It shall not be necessary for the
consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall deliver to the
Holders a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

 SECTION 9.03. Consents in Connection with Purchase, Tender or Exchange. 

A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with a purchase, tender or exchange of
such Holder’s Notes shall not be rendered invalid by such purchase, tender or exchange. 

  
 83 












 SECTION 9.04. Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of
such Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder
of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its
terms and, except as provided in the second succeeding paragraph, thereafter binds every Holder. 
 The Company may, but shall not be
obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the second to last sentence of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or revoke any consent previously given, whether or not
such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date except to the extent that the requisite number of consents to the amendment, supplement or waiver have
been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.04. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses
(a) through (j) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that
evidences the same indebtedness as the consenting Holder’s Note. 
 SECTION 9.05. Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company, in
exchange for all Notes, may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment,
supplement or waiver. 
 SECTION 9.06. Trustee to Sign Amendments, etc. 

The Trustee shall sign any amendment or supplemental indenture or grant any waiver authorized pursuant to this Article 9 if the
amendment or supplemental indenture or waiver does not adversely affect its rights, duties, liabilities or immunities. If any such amendment, supplemental indenture or waiver does adversely affect the rights, duties, liabilities or immunities of the
Trustee, the Trustee may, but need not, sign such amendment, supplemental indenture or grant such waiver. In executing any such amendment, supplemental indenture or waiver, the Trustee shall be entitled to receive and (subject to
Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment, supplemental indenture or waiver is authorized or permitted by
this Indenture and the Collateral Documents, constitutes the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms and that all conditions precedent to such supplemental indenture have been complied
with, subject to customary assumptions and qualifications. 
 SECTION 9.07. Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given, made or
taken by Holders shall be in writing may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 

  
 84 












 Without limiting the generality of this Section, unless otherwise provided in or pursuant to
this Indenture, (i) a Holder, including the Depository or its nominee that is a Holder of a Global Note, may give, make or take, by an agent or agents duly appointed in writing, any request, demand, authorization, direction, notice, consent,
waiver or other action provided in or pursuant to this Indenture to be given, made or taken by Holders, and the Depository or its nominee that is a Holder of a Global Note may duly appoint in writing as its agent or agents members of, or
participants in, the Depository holding interests in such Global Note in the records of the Depository; and (ii) with respect to any Global Note, any consent or other action given, made or taken by an Agent Member by electronic means in
accordance with the “Automated Tender Offer Procedures” system or other customary procedures of, and pursuant to authorization by, the Depository shall be deemed to constitute the Act of the Holder of such Global Note, and such Act shall
be deemed to have been delivered to the Company and the Trustee upon the delivery by the Depository of an “agent’s message” or other notice of such consent or other action having been so given, made or taken in accordance with the
applicable policies and procedures of the Depository. 
 (b) The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing
acknowledged to him the execution thereof. Where such execution is by a Person acting in a capacity other than such Person’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of the authority of the
Person executing the same. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 

(c) The ownership of Notes shall be proved by the Register. 

(d) Without limiting the foregoing, a Holder entitled hereunder to give, make or take any action hereunder with regard to any particular Note
may do so, or duly appoint in writing any Person or Persons as its agent or agents to do so, with regard to all or any part of the principal amount of such Note. 

ARTICLE 10 
 GUARANTEES OF NOTES

 SECTION 10.01. Subsidiary Guarantees. 

Subject to this Article 10, each of the Guarantors hereby absolutely and unconditionally guarantees, jointly with the other Guarantors
and severally, as primary obligor and not merely as surety, on a senior basis to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and their respective successors and assigns, irrespective of the validity and
enforceability of this Indenture, the Notes or the Obligations of the Company hereunder and thereunder, that: 
 (a) the
principal of, and premium, if any, interest, if any, on, or Additional Amounts, if any, on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise, and interest on
the overdue principal of, and premium, if any, and (to the extent permitted by law) interest, if any, on, and Additional Amounts, if any, on, the Notes, and all other payment Obligations of the Company to the Holders, the Trustee or the First Lien
Collateral Agent under this Indenture or the Notes will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and 

(b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be
promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise. 

  
 85 












 Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors
will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is an absolute, unconditional, present and continuing guarantee of payment and performance (and not a guarantee of collection) and is in no way
conditioned upon any attempt to collect from the Company or any other Guarantor or any other action, occurrence or circumstance whatsoever. 

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to
enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its
Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and this Indenture. 

If any Holder, the Trustee or the First Lien Collateral Agent is required by any court or otherwise to return to the Company, the Guarantors,
or any Custodian, trustee or other similar official acting in relation to any of the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee, First Lien Collateral Agent or such Holder, the Subsidiary Guarantees, to
the extent theretofore discharged, shall be reinstated in full force and effect. 
 Each Guarantor further agrees that, as between the
Guarantors, on the one hand, and the Holders, the Trustee and the First Lien Collateral Agent, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of its
Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in
Article 6, such Obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantees. 

SECTION 10.02. Releases of Guarantees. 

The Guarantee of a Guarantor will be automatically and unconditionally released: (1) in connection with any sale, transfer or other
disposition (including by merger, consolidation, amalgamation, distribution, dividend or otherwise) of all or substantially all of the assets of such Guarantor to a Person that is not (either before or after giving effect to such transaction) the
Company or a Restricted Subsidiary, if the sale or other disposition is conducted in accordance with Sections 4.10 and 5.01(b), as applicable; (2) in connection with any sale, transfer or other disposition (including by merger,
consolidation, amalgamation, distribution, dividend or otherwise) of all of the Capital Stock of such Guarantor, following which such Guarantor is no longer a Restricted Subsidiary of the Company, if the sale or other disposition is conducted in
accordance with Sections 4.10 and 5.01(b), as applicable; (3) upon Legal Defeasance, Covenant Defeasance or Discharge in accordance with Article 8; (4) unless an Event of Default has occurred and is continuing, upon the
dissolution or liquidation of such Guarantor in compliance with Section 5.01(b); or (5) if the Company designates such Guarantor as an Unrestricted Subsidiary or an Immaterial Subsidiary in accordance with this
Indenture. 
 Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that any
of the conditions described in the foregoing clauses (1) through (5) has occurred, the Trustee shall execute any documents reasonably requested by the Company at the Company’s expense in order to evidence the release of any Guarantor from
its obligations under its Guarantee. Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest, premium, if any, and Additional Amounts, if any, on, the Notes and for the
other obligations of such Guarantor under this Indenture as provided in this Article 10.

 SECTION 10.03. Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee
of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state or foreign law to the extent applicable
to any Guarantee, and with respect to any Guarantor organized under the laws of Malaysia, the amount of the obligations guaranteed by such Guarantor (and the value of any assets provided by such Guarantor as security for such obligations) shall be
in, but not in excess of, the maximum amount permitted by any Legal Requirement applicable to such Guarantor, including, but not limited to, the Malaysian Financial Services Act of 2013, as amended, and any rules, regulations, or rulings promulgated
by Bank Negara Malaysia (or any successor central bank of Malaysia). The obligations of each Guarantor under its Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such
Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this
Indenture, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state or foreign law and not otherwise being void or voidable under any similar laws
affecting the rights of creditors generally. Each Guarantor that makes a payment under its Guarantee shall be entitled, upon payment in full of all guaranteed Obligations under this Indenture, to seek contribution from each other Guarantor in an
amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all Guarantors at the time of such payment determined in accordance with GAAP. 

SECTION 10.04. “Trustee” to Include Paying Agent. 

In case at any time any Paying Agent other than the Trustee shall have been appointed and be then acting hereunder, the term
“Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if
such Paying Agent were named in this Article 10 in place of the Trustee. 
 SECTION 10.05. Execution and Delivery. 

The execution by each Guarantor of this Indenture (or a supplemental indenture hereto) evidences the Guarantee of such Guarantor, whether or
not the person signing as an Officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Guarantee set forth in this
Indenture on behalf of each Guarantor. 
 SECTION 10.06. Subrogation. 

Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by the Guarantor pursuant to
the provisions of Section 10.01; provided that no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the
Company under this Indenture or the Notes shall have been paid in full. 
 ARTICLE 11 

SECURITY 
 SECTION 11.01.
Collateral Documents; Additional Collateral. 
 (a) Security Agreements. In order to secure the due and punctual payment of the First
Lien Obligations, (i) upon the Issue Date, the Company and the Guarantors shall execute Collateral Documents granting to the Collateral Agent for the benefit of the Holders and holders of other First Lien Obligations (in accordance with the
Collateral Documents) a first priority perfected Lien in the Collateral, and (ii) after the Issue Date, in accordance with the provisions of Sections 4.13 and 4.26 and this Article 11, if (I) any asset of the type
which is required to constitute Collateral pursuant to this Indenture or the Collateral Documents is acquired by any Guarantor and such 

  
 87 












 
asset is not automatically subject to a first-priority perfected Lien in favor of the First Lien Collateral Agent or (II) a Subsidiary of the Company that is not already a Guarantor is
required to become a Guarantor pursuant to Section 4.13, then such Guarantor or such other Subsidiary shall, as soon as practicable after the acquisition of the applicable asset or the occurrence of the event requiring such
Subsidiary to become a Guarantor (and, in any event, within 20 Relevant Business Days after such acquisition or event (or as soon as practicable where applicable local laws requires additional time for compliance with applicable legal
requirements)), execute and deliver the necessary Collateral Documents in order to grant to the First Lien Collateral Agent a first-priority perfected Lien (subject to Permitted Collateral Liens) in all assets of such Guarantor or such other
Subsidiary that are required to, but do not already, constitute Collateral. In each case described above, each Guarantor shall execute and deliver such other Collateral Documents, deliver any certificates (including in the case of real property,
title insurance) to the First Lien Collateral Agent in respect of the applicable Collateral as required by this Indenture and the applicable Collateral Documents and take all other appropriate actions to ensure the First Lien Collateral Agent, for
the benefit of the Holders and holders of other First Lien Obligations, has a first-priority perfected Lien therein. For the avoidance of doubt, the Guarantors shall not be required to grant a security interest in, and the Collateral shall not
include, any Excluded Property. 
 The Company shall cause every Guarantor to make all filings (including filings of continuation statements
and amendments to Uniform Commercial Code financing statements in the United States (or the applicable political subdivision, territory or possession thereof) that may be necessary to continue the effectiveness of such Uniform Commercial Code
financing statements) and take all other actions as are reasonably necessary or required by the Collateral Documents to maintain (at the sole cost and expense of the Guarantors) the security interest created by the Collateral Documents in the
Collateral as a first-priority perfected Lien. 
 All references to a “first-priority perfected Lien” in this
Section 11.01(a) shall be understood to be subject to Permitted Collateral Liens, if any and the terms of the Intercreditor Agreement. 

(b) Additional Collateral. The Company shall, and shall cause every other Collateral Grantor to, from time to time take the actions
required by Section 4.26. 
 (c) Notwithstanding Section 11.01(a), to the extent any
security interest in the Collateral or any deliverable related to the perfection of security interests in the Collateral (other than Collateral the security interest in which may be perfected by the filing of a Uniform Commercial Code financing
statement or the delivery of certificated securities (if any)) cannot be provided and/or perfected on the Issue Date (x) without undue burden or expense or (y) after the Company and the Guarantors’ use of commercially reasonable
efforts to do so, then perfection of such security interest(s) and/or delivery of such deliverables may be completed after the Issue Date, but no later than 120 days thereafter. 

SECTION 11.02. [Reserved]. 

SECTION 11.03. Releases of Collateral. 

The Notes Obligations will no longer be required to be secured by Liens on Collateral, and subject to the terms of the Intercreditor Agreement
and the other Collateral Documents, the Liens securing the Notes Obligations will be released: 
 (1) in whole, upon the full
and final payment and performance of all Notes Obligations; 
 (2) in part, with respect to any asset constituting
Collateral, if such Collateral is sold or otherwise disposed of (x) to the Company or a Guarantor in a transaction permitted by the terms of this Indenture; provided that such Collateral shall be pledged as Collateral under the
Collateral Documents contemporaneously with such partial release of Liens and sale or disposition to the Company or a Guarantor, in accordance with the requirements of this Indenture and the Collateral Documents; or (y) to a Person that is not
(either before or after giving effect to such transaction) the Company or a Guarantor in a transaction that is not prohibited by this Indenture, subject to 

  
 88 












 
compliance with Section 4.10 (other than the provisions thereof relating to the future use of the proceeds of such sale or other disposition), and, in each case, the
Company has delivered to the First Lien Collateral Agent and the Trustee an Officers’ Certificate certifying to such effect and Opinion of Counsel (with customary assumptions and qualifications for such types of opinion); provided that
(i) pending its application or use in compliance with Section 4.10, any cash received from a disposition of Collateral shall be deposited in a deposit account controlled by the First Lien Collateral Agent and held as
Collateral and, from such deposit account, the applicable Collateral Grantor may withdraw funds to deploy the proceeds of an Asset Sale in compliance with Section 4.10, and (ii) to the extent that any Collateral is
sold or otherwise disposed of in accordance with the terms of Section 4.10, the non-cash consideration (including any Designated Noncash Consideration) received shall be pledged as
Collateral under the Collateral Documents contemporaneously with such sale or disposition, in accordance with the requirements of this Indenture and the Collateral Documents; 

(3) in whole, upon Legal Defeasance pursuant to Section 8.02, Covenant Defeasance pursuant to
Section 8.03 or Discharge pursuant to Section 8.08; 
 (4) in part, with
respect to the assets of any Guarantor that is released from its Guarantee in accordance with Section 10.02;

 (6) in whole or in part, as provided in the Intercreditor Agreement or the other Collateral Documents. 

SECTION 11.04. Release Documentation. 

Upon compliance with the conditions to release of all or any portion of the Collateral set forth in Section 11.03,
the First Lien Collateral Agent and the Trustee shall forthwith take all action reasonably requested by the Company (at the expense of the Company, and accompanied by an Officers’ 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, without recourse or warranty of any kind or nature, that is
authorized to be released pursuant to Section 11.03, and shall deliver such Collateral in its possession to the applicable Collateral Grantor, including, without limitation, executing and delivering releases and
satisfactions wherever required. Notwithstanding anything herein to the contrary, in the event of any transfer, sale or other disposition of all or any part of the assets of a Collateral Grantor constituting Collateral to the Company or any other
Collateral Grantor (including by way of merger, consolidation or amalgamation) in a transaction permitted by the terms of this Indenture, the Trustee and the First Lien Collateral Agent shall forthwith take all action reasonably requested by the
Company (at the expense of the Company, and accompanied by an Officers’ Certificate and Opinion of Counsel that the conditions precedent to such release have been satisfied) to release such Collateral if and to the extent necessary to
consummate such transfer, sale or disposition; provided that arrangements satisfactory to the Trustee and the First Lien Collateral Agent have been made for the contemporaneous pledge of such Collateral by the successor in accordance with the terms
of the Collateral Documents and this Indenture. 
 SECTION 11.05. Possession and Use of Collateral; No Impairment of the Security Interests.

 (a) So long as no Default or Event of Default has occurred and is continuing, and subject to the terms of this Indenture and the

Intercreditor Agreement, Sections 5.01 and 4.10 hereof and the other Collateral Documents. 

  
 89 












 (b) The Company shall not, and shall not permit any other Collateral Grantor to, 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 Collateral Documents, (except as
expressly set forth in this Indenture or the Collateral Documents, including any action that would result in a Permitted Collateral Lien). 

(c) No Collateral Grantor will take any action or otherwise attempt to enforce any claim or maritime Lien held by it against any Collateral
Vessel that has priority over any claim or Lien of the First Lien Collateral Agent in respect of such Collateral Vessel, including any claims or Liens arising under the Vessel Mortgages.

continuance of an Event of Default: 
 (1) all rights of the Company and the Guarantors to exercise such voting or other
consensual rights pertaining to its Collateral will cease, and all such rights will become vested in the First Lien Collateral Agent, which, to the extent permitted by law, will have the sole right to exercise such voting and other consensual rights
in accordance with the Collateral Documents; 
 (2) all rights of the Company and the Guarantors to receive all cash
dividends, principal, interest and other payments made upon or with respect to the Collateral will cease and such cash dividends, principal, interest and other payments will be paid to the First Lien Collateral Agent in accordance with the

the Trustee and the Holders of the Notes in accordance with the provisions of this Indenture.

permitted to release all or any portion of the Collateral from the Liens created by the Collateral Documents and foreclose on the Collateral following an Event of Default, in each case in accordance with the applicable provisions of the Collateral
Documents.

Collateral Agent of a written request of the Company in the form of an Officers’ Certificate, the First Lien Collateral Agent is hereby authorized to execute and enter into, and shall execute and enter into, without the further consent of any

Securities Act (“Rule 144A”) or in reliance on Regulation S (“Regulation S Notes”) under the U.S. Securities Act (“Regulation S”), in each case as provided in a Purchase

 App. - 1 












 
other custodian as the Depository may direct), and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided. Beneficial interests in a Restricted Global Note representing Initial Notes sold in reliance on either Rule 144A or Regulation S may be held through Euroclear or Clearstream, as indirect participants in the Depository. The
aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter provided. Unrestricted Notes issued in global form and
Restricted Global Notes are each referred to herein as a “Global Note” and are collectively referred to herein as “Global Notes.” 

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Note deposited with or on behalf of the Depository.

 The Company shall execute and the Trustee shall, in accordance with this Section 2.1(b) and Section 2.02 of the Indenture,
authenticate and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depository for such Global Note or Global Notes or the nominee of such Depository and (b) shall be delivered by the Trustee to such
Depository or pursuant to such Depository’s instructions or held by the Trustee as Notes Custodian for the Depository. 
 Members of,
or participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect to any Global Note held on their behalf by the Depository or by the Trustee as the custodian of the Depository or
under such Global Note, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depository as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent
Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Note. 

Prior to the expiration of the period through and including the 40th day after the later of the commencement of the offering of any Initial
Notes and the closing of such offering (such period, the “Restricted Period”), beneficial interests in the Restricted Global Note representing Regulation S Notes may be transferred or exchanged for beneficial interests in the
Restricted Global Note representing Rule 144A Notes only if (i) such exchange occurs in connection with a transfer of the Notes pursuant to Rule 144A, (ii) the transferor first delivers to the Trustee a written certificate (in the form
provided in Exhibit 1 hereto) to the effect that the Notes are being transferred to a Person who the transferor reasonably believes to be a QIB within the meaning of Rule 144A and is purchasing for its own account or the account of a QIB, in each
case in a transaction meeting the requirements of Rule 144A, and (iii) the transfer is in accordance with all applicable securities laws of the states of the United States and other jurisdictions. After the expiration of the Restricted Period,
such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Note representing Regulation S Notes. 

Beneficial interests in a Restricted Global Note representing Rule 144A Notes may be transferred to a Person who takes delivery in the form of
an interest in the Restricted Global Note representing Regulation S Notes, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Registrar a written certificate (in the form provided in Exhibit
1 hereto) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available). 

(c) Certificated Notes. Except as provided in Section 2.3, owners of beneficial interests in Global Notes shall not be entitled to
receive physical delivery of certificated Notes. Certificated Notes shall not be exchangeable for beneficial interests in Global Notes. 

2.2 Transfer and Exchange. 

(a) Transfer and Exchange of Global Notes. (i) The transfer and exchange of Global Notes or beneficial interests therein shall be
effected through the Depository, in accordance with the Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note shall
deliver to the Trustee a written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited 

  
 App. - 2 












 
with a beneficial interest in the Global Note. The Trustee shall, in accordance with such instructions instruct the Depository to credit to the account of the Person specified in such
instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred. 

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another
Global Note, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be so
transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred. 

(iii) Notwithstanding any other provisions of this Appendix, a Global Note may not be transferred as a whole except by the
Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. 

(b) Legend. 

(i) Except as permitted by the following paragraphs (ii) and (iii), each Note certificate evidencing the Global Notes and
the certificated Notes (and all Notes issued in exchange therefor or in substitution thereof) shall bear the applicable legend in substantially the following form (“Restricted Notes Legend”): 

If the Note is a Rule 144A Note: 

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE
SECURITIES LAWS. NEITHER THIS NOTE NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. THE HOLDER OF THIS NOTE, BY ITS ACCEPTANCE HEREOF
(1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS A NON-U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE
TRANSACTION WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT AND IN ACCORDANCE WITH THE LAWS APPLICABLE TO SUCH PURCHASER IN THE JURISDICTION IN WHICH SUCH PURCHASE IS MADE, OR (C) IT IS AN “ACCREDITED INVESTOR” WITHIN THE
MEANING OF RULE 501 UNDER THE SECURITIES ACT AND (2) AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH NOTE, PRIOR TO THE EXPIRATION OF THE APPLICABLE HOLDING PERIOD WITH RESPECT TO RESTRICTED SECURITIES SET FORTH IN RULE 144 UNDER THE
SECURITIES ACT, ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE NOTES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN
RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT AND IN ACCORDANCE WITH THE LAWS APPLICABLE TO IT IN THE JURISDICTION IN WHICH SUCH PURCHASE IS MADE,
(D) TO AN “ACCREDITED INVESTOR” WITHIN THE MEANING OF RULE 501 UNDER THE SECURITIES ACT THAT IS ACQUIRING THE NOTE FOR ITS OWN ACCOUNT, OR FOR THE ACCOUNT OF SUCH AN ACCREDITED INVESTOR, FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO,
OR FOR OFFER OR SALE IN CONNECTION WITH, ANY 

  
 App. - 3 












 
DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, (E) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT OR (F) PURSUANT TO ANOTHER AVAILABLE
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S, OR REGISTRAR’S, AS APPLICABLE, RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) OR (F) TO
REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS NOTE COMPLETED AND
DELIVERED BY THE TRANSFEROR TO THE TRUSTEE OR REGISTRAR. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE EXPIRATION OF THE APPLICABLE HOLDING PERIOD WITH RESPECT TO RESTRICTED SECURITIES SET FORTH IN RULE 144 UNDER THE
SECURITIES ACT. 
 If the Note is a Regulation S Note: 

THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT. 

(ii) Upon a sale or transfer after, in the case of (A) any Note acquired pursuant to Rule 144A, the applicable holding
period under Rule 144A under the Securities Act (the “Resale Restriction Termination Date”) therefor, or (B) any Note acquired pursuant to Regulation S, the expiration of the Restricted Period, all requirements that such Note
bear a Restricted Notes Legend shall cease to apply and a Global Note without the applicable Restricted Notes Legend may be issued to the transferee of such Note. The applicable Restricted Notes Legend on any Note shall be removed at the written
request of the Company on or after the Resale Restriction Termination Date (with respect to any Rule 144A Note) or the Restricted Period (with respect to any Regulation S Note) therefor, as applicable. Without limiting the generality of the
preceding sentence, the Company may effect such removal by issuing and delivering, in exchange for such Transfer Restricted Security, an Unrestricted Note without such legend, registered to the same Holder and in an equal principal amount and in the
case of Global Notes, complying with the Depository’s procedures, and (A) upon receipt by the Trustee of a written order of the Company stating that the Resale Restriction Termination Date (with respect to any Rule 144A Note) or the
Restricted Period (with respect to any Regulation S Note) therefor, as applicable, to such Transfer Restricted Security has occurred and requesting the authentication and delivery of an Unrestricted Note in exchange therefor (which order shall not
be required to be accompanied by any Opinion of Counsel or any other document) given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date
or termination of the Restricted Period, as applicable) and (B) approval by the Depository, the Trustee shall authenticate and deliver such Unrestricted Note to the Depository or pursuant to such Depository’s instructions or hold such Note
as Note Custodian for the Depository and shall request the Depository to, or, if the Trustee is Note Custodian of such Transfer Restricted Security, shall itself, surrender such Transfer Restricted Security in exchange for such Unrestricted Note
without such legend and thereupon cancel such Transfer Restricted Security so surrendered, all as directed in such order. For purposes of determining whether the Resale Restriction Termination Date (with respect to any Rule 144A Note) or the
Restricted Period (with respect to any Regulation S Note) therefor, as applicable, has occurred with respect to any Notes evidenced by a Transfer Restricted Security or delivering any order pursuant to this Section 2.2(b)(ii) with respect to
such Notes, (i) only those Notes which a Principal Officer of the Company actually knows (after reasonable inquiry) to be or to have been owned by an Affiliate of the Company shall be deemed to be or to have been, respectively, owned by an
Affiliate of the Company; and (ii) “Principal Officer” means the principal executive officer, the principal financial officer, the treasurer or the principal accounting officer of the Company. 

  
 App. - 4 












 For purposes of this Section 2.2(b)(ii), all provisions relating to the removal of the
legend set forth in paragraph (i) above shall relate, if the Resale Restriction Termination Date (with respect to any Rule 144A Note) or the Restricted Period (with respect to any Regulation S Note) therefor, as applicable, has occurred only
with respect to a portion of the Notes evidenced by a Transfer Restricted Security, to such portion of the Notes so evidenced as to which the Resale Restriction Termination Date (with respect to any Rule 144A Note) or the Restricted Period (with
respect to any Regulation S Note) therefor, as applicable has occurred. 
 Each Holder of any Note evidenced by any Restricted Global Note,
by its acceptance thereof, (A) authorizes and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions,
on such Holder’s behalf, as the Depository or the Trustee may require to effect, and (C) upon the request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the
Depository or the Trustee may require, or as shall otherwise be necessary to effect, the removal of the legend set forth in Section 2.2(b)(i) (including by means of the exchange of all or the portion of such Restricted Global Note evidencing
such Note for a certificate evidencing such Note that does not bear such legend) at any time after the Resale Restriction Termination Date (with respect to any Rule 144A Note) or the Restricted Period (with respect to any Regulation S Note)
therefor, as applicable. 
 (iii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer
Restricted Security represented by a Restricted Global Note) pursuant to Rule 144, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a Note that does not bear the legend set forth above and rescind
any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the
reverse of the Note). 
 (iv) Notes issued upon any sale or transfer of a Transfer Restricted Security (including any
Transfer Restricted Security represented by a Restricted Global Note) to an Accredited Investor pursuant to Rule 501 under the Securities Act shall be issued in definitive, fully registered non-global form
without interest coupons and shall not be issued as Global Notes; provided, however, that certificated Notes may be transferred to QIBs in accordance with Rule 144A or acquired in reliance on Regulation S and exchanged for interests in Global Notes
pursuant to this Section 2.2. 
 (v) In the event that a Global Note is exchanged for certificated Notes pursuant this
Appendix A, such Notes may be transferred or exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.2 (including the certification requirements set forth on the reverse of the
Notes intended to ensure that such transfers comply with Rule 144A, Regulation S or such other applicable exemption from registration under the Securities Act, as the case may be) and such other reasonable procedures as may from time to time be
adopted by the Company and notified to the Trustee in writing. 
 (c) Cancellation or Adjustment of Global Note. At such time as all
beneficial interests in a Global Note have either been exchanged for certificated Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior
to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, purchased or canceled, or if any certificated Note is exchanged for such a beneficial interest, the principal amount of Notes
represented by such Global Note shall be reduced or increased, as appropriate, and an adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the
Trustee or the Notes Custodian, to reflect such reduction or increase, as the case may be.

(ii) No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any transfer tax, assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon any exchange or transfer pursuant to
Sections 2.10, 3.06, 3.08, 3.09, 4.10, 4.15 and 9.05 of the Indenture). 
 (iii) The Registrar shall not be required to
register the transfer or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15
days before selection of Notes to be redeemed. 
 (iv) Prior to the due presentation for registration of transfer of any
Note, the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if
any, interest, if any, on, or Additional Amounts, if any, on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar shall be
affected by notice to the contrary. 
 (v) All Notes issued upon any transfer or exchange pursuant to the terms of the
Indenture shall evidence the same debt and shall be entitled to the same benefits under the Indenture as the Notes surrendered upon such transfer or exchange. Accordingly, for purposes of clause (1) of Section 4.09(b) of the Indenture,
Notes “issued on the Issue Date” shall be deemed to refer to and include any Notes issued in exchange for, or upon registration of transfer of, or in lieu of, any such Notes (or any predecessor Notes thereof) pursuant to the Indenture.

 (e) No Obligation of the Trustee. 

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a
participant in the Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery
to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of optional redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to
be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Note). The rights of
beneficial owners in any Global Note shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the
Depository with respect to its members, participants and any beneficial owners. 
 (ii) The Trustee shall have no obligation
or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among
Depository participants, members or beneficial owners in any Global Note) 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 the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

transferred to the beneficial owners thereof in the form of certificated Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.2
of this Appendix and (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Note or if at any time such Depository ceases to be a “clearing agency” registered under the
Exchange Act and in either case the Company fails to appoint a successor depository within 90 days, (ii) the Company, at its option, but subject to the Depository’s requirements, notifies the Trustee in writing that it elects to cause the
issuance of the certificated Notes, or (iii) an Event of Default has occurred and is continuing and the Depository notifies the Trustee of its decision to exchange the Global Notes for certificated Notes.

the Notes Custodian to the Trustee located at its Corporate Trust Office to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global
Note, an equal aggregate principal amount of certificated Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section shall be executed, authenticated and delivered only in minimum denominations equal to
$2,000 or an integral multiple of $1,000 in excess thereof, and registered in such names as the Depository shall direct. Any certificated Note delivered in exchange for an interest in a Global Note shall, except as otherwise provided by
Section 2.2(b), bear a Restricted Notes Legend.

shall be entitled to grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes.

 [FORM OF REVERSE SIDE OF NOTE] 

9.250% First Lien Notes due 2023 

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated. 
 1. Interest. Vantage Drilling International, a Cayman Islands exempted company (together with its successors and
assigns under the Indenture hereinafter referred to, the “Company”), promises to pay interest on the unpaid principal amount of this Note at 9.250% per annum. The Company will pay interest semi-annually in arrears on May 15 and
November 15 of each year (each an “Interest Payment Date”), commencing May 15, 2019. In certain circumstances specified in the Indenture, the Company may be required to pay Additional Amounts with respect to the
Notes. Whenever in this Note there is mentioned, in any context, the payment of amounts based upon the principal amount of this Note or of principal, interest or of any other amount payable under, or with respect to, this Note, 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. If any date for payment on the Notes falls on a day that is not a Business Day,
such payment may be made on the next succeeding Business Day with the same force and effect as if made on the due date, and no additional interest will accrue solely as a result of such delayed payment. Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is
authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of Notes, in which
case interest shall accrue from the date of authentication. The Company shall pay (i) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand
at a rate that is equal to the then applicable interest rate on the Notes and (ii) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Amounts, if any
(without regard to any applicable grace periods), from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 2. Method of Payment. The Company will pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 1 or November 1 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before
such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Holders must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, together with accrued and
unpaid interest and Additional Amounts, if any, due at maturity. Any Notes in certificated form will be payable as to principal, premium, if any, interest, if any, and Additional Amounts, if any, at the office or agency of the Paying Agent and
Registrar maintained for such purpose within the contiguous United States, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that
payment by wire transfer of immediately available funds to an account in the United States will be required with respect to any amounts due on all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions
to the Company or the Paying Agent. Notwithstanding the foregoing, if this Note is a Global Note, payment may be made pursuant to the applicable procedures of the Depository as permitted in the Indenture. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 3. Paying
Agent and Registrar. Initially, U.S. Bank National Association, the trustee (the “Trustee”) under the Indenture, will act as Paying Agent and Registrar at its corporate trust office at 225 Asylum Street, 23rd Floor, Hartford,
Connecticut 06103. The Company may appoint and change any Paying Agent or Registrar without notice to any Holder. Other than for purposes of effecting a redemption or an offer to purchase described in Sections 3.07, 3.08, 3.09, 4.10 and 4.15 of the
Indenture or in connection with a Legal Defeasance, Covenant Defeasance or Discharge, the Company or any of its Subsidiaries may act in any such capacity. 

  
 Exhibit 1 to App. - 5













 4. Indenture. Vantage Drilling International issued the Notes under an Indenture
dated as of November 30, 2018 (“Indenture”) among Vantage Drilling International, the guarantors party thereto and the Trustee. The Notes are subject to the terms of the Indenture, and Holders are referred to the
Indenture for a statement of such terms. The Notes are first-lien senior secured obligations of the Company. The Company shall be entitled, subject to its compliance with Sections 4.09 and 4.12 of the Indenture, to issue Additional Notes pursuant to
Section 2.14 of the Indenture. In the event of a conflict between the Indenture and this Note, the terms of the Indenture shall control. 

5. Optional Redemption.

not including, the applicable redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in an amount not greater than the net cash proceeds received by the
Company of one or more Equity Offerings; provided that: 
 (1) at least 65% of the aggregate principal amount of Notes
(including any Additional Notes) issued under the Indenture (excluding any Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 

(2) the redemption occurs within 120 days after the date of the closing of such Equity Offering. 

(b) At any time prior to May 15, 2020, the Company may, at its option, redeem the Notes, in whole or in part, at one time or from time to
time, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional Amounts, if any, to, but not including, the applicable redemption date,

price equal to 103% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, to, but not including, the redemption date, subject to the rights of Holders of record on the relevant record date to
receive interest due on the relevant Interest Payment Date. 
 (d) On or after May 15, 2020, the Company may, at its option, redeem the
Notes, in whole or in part, at one time or from time to time, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed, to, but

price equal to 100% of the outstanding principal amount of Notes, plus accrued and unpaid interest (if any) to, but not including, the applicable redemption date, plus all Additional Amounts, if any, then due and which will become due as a result of
the redemption or otherwise (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in the event that the Company determines in good faith that the Company or any
Guarantor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes or the Guarantees, Additional Amounts, and such obligation cannot be avoided by taking reasonable measures
available to the Company or the relevant Guarantor, as 

  
 Exhibit 1 to App. - 6













 
applicable (including making payment through a Paying Agent located in another jurisdiction but not, for the avoidance of doubt, changing the jurisdiction of incorporation of the Company or the
relevant Guarantor), as a result of: 
 (1) a change in or an amendment to the laws or treaties (including any regulations or
rulings promulgated thereunder) of any Specified Tax Jurisdiction affecting taxation, which change or amendment is announced or becomes effective on or after the Issue Date (or, if the Specified Tax Jurisdiction was not a Specified Tax Jurisdiction
on the Issue Date, the date on which such Specified Tax Jurisdiction became a Specified Tax Jurisdiction); or 
 (2) any
change in or amendment to any official position of a taxing authority in any Specified Tax Jurisdiction regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or

Specified Tax Jurisdiction became a Specified Tax Jurisdiction); 
 provided, however, that in the case of Additional
Amounts required to be paid as a result of the Company or relevant Guarantor conducting business other than in the place of its incorporation or organization, such amendment or change must be announced or become effective on or after the date in

outstanding amount of Notes held by such Holder shall be redeemed. No Notes of $2,000 or less can be redeemed in part. On and after the redemption date, interest ceases to accrue on the Notes or portions thereof called for redemption, subject to
satisfaction of any conditions thereto. 
 7. Mandatory Redemption. 

Except as set forth in Paragraph 8 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect
to the Notes or to repurchase the Notes at the option of the Holders. 

  
 Exhibit 1 to App. - 7













 8. Repurchase at Option of Holder. 

(a) If a Change of Control occurs, the Company will be required to make an offer (a “Change of Control Offer”) to
repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid
interest and Additional Amounts, if any, to, but not including, the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of record on the relevant record date to receive interest due on
the relevant Interest Payment Date. Within 30 days following a Change of Control, and to the extent that the Company has not exercised its option to redeem all of the Notes as described in Paragraph 5 above, the Company shall mail a notice of the
Change of Control Offer to each Holder and the Trustee and the Paying Agent describing the transaction or transactions that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by
Section 4.15 of the Indenture. 
 (b) If the Company or any Restricted Subsidiary consummates an Asset Sale, within 10 Business Days of
each date on which the aggregate amount of Excess Proceeds exceeds $20 million, the Company may be required to make an Asset Sale Offer in accordance with Sections 3.09 and 4.10 of the Indenture. 

(c) At the time the Company or any Restricted Subsidiary has received Petrobras Recovery Proceeds in the form of cash or Cash Equivalents of
at least $75 million, the Company will, within 10 Business Days of receipt thereof, be required to make a Petrobras Offer in accordance with Section 3.08 of the Indenture. 

9. Guarantees. The payment by the Company of the principal of, and premium, if any, interest, if any, on, or Additional Amounts, if
any, on, the Notes will be absolutely and unconditionally guaranteed on a joint and several basis by the Guarantors, as primary obligor and not merely as a surety, to the extent set forth in the Indenture. 

10. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer
documents, and the Company may require a Holder to pay any taxes due on transfer or exchange. The Registrar need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any
Note being redeemed in part. Also, the Company and the Registrar need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 

11. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes. 

12. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Notes and the Collateral Documents may be
amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or
exchange for, the Notes), and any existing Default or Event of Default or compliance with any provision of the Indenture, the Notes or the Collateral Documents may be waived with the consent of the Holders of a majority in aggregate principal amount
of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange for, Notes). Without the consent of any Holder of, the Indenture, the Notes and the Collateral Documents
may be amended or supplemented with respect to certain matters specified in the Indenture. 
 13. Defaults and Remedies. If any Event
of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the Notes to be due and
payable immediately. Notwithstanding the preceding, in the case of an Event of Default arising from such events of bankruptcy, insolvency or reorganization described in Section 6.01(i) or 6.01(j) of the Indenture with respect to the Company or
a Guarantor, all outstanding Notes shall become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the Collateral Documents except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power conferred on it with respect to the Notes. The Trustee may withhold from Holder notice of any
continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on, the


  
 Exhibit 1 to App. - 8













 
Notes. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all the Notes, rescind an acceleration or
waive any existing Default or Event of Default and its consequences under the Indenture, except as provided in the Indenture. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and within
10 Business Days of any of its Officers or any of the Company’s Officers becoming aware of any Default or Event of Default, the Company is required to deliver to the Trustee a statement specifying such Default or Event of Default. 

14. Defeasance and Discharge. The Notes are subject to defeasance and discharge upon the terms and conditions specified in the
Indenture. 
 15. No Recourse Against Others. No present, past or future director, officer, employee, incorporator or stockholder of
