registered Holder will be treated as the owner of such Note for all purposes. 
 The terms and provisions contained in the Notes shall
constitute, and are hereby expressly made, a part of this Indenture, and the Issuers and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any

Each Global Note shall represent such of the outstanding Notes as shall be specified therein, and each shall provide that it
shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges,
redemptions and transfers of interests. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of

reliance on Regulation S under the Securities Act (“Regulation S”). After such initial issuance, Initial Notes that are Transfer Restricted Notes may be transferred to QIBs in reliance on Rule 144A or outside the

 The Issuers shall
execute and the Trustee shall, in accordance with Section 2.1(a) and Section 2.1(b) and this Section 2.1(c) and Section 2.2, authenticate and deliver the Global Notes that (i) shall be registered in the name of the

SECTION 2.2. Execution and Authentication. An Officer of each Initial Co-Issuer shall sign

time a Note is authenticated, the Note shall nevertheless be valid. 
 A Note shall not be valid until authenticated by the manual signature
of a Responsible Officer of the Trustee. The signature of a Responsible Officer of the Trustee shall be conclusive evidence that the Note has been authenticated under this Indenture. 

  
 36 

 The Trustee shall, upon receipt of a written order of the Issuers signed by one Officer of each
Issuer directing the Trustee to authenticate the Notes and certifying that all conditions precedent to the issuance of the Notes contained herein have been complied with and receipt of an Opinion of Counsel, authenticate Notes for original issue in
the aggregate principal amount stated in such written order. 
 The Trustee may appoint an authenticating agent reasonably acceptable
to the Issuers to authenticate 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 or agents. An authenticating agent has the same rights as an Agent to deal with Holders or the Issuers or an Affiliate of any Issuer. 

SECTION 2.3. Registrar; Paying Agent. The Issuers shall maintain (i) an office or agency where Notes may be presented for
registration of transfer or for exchange (“Registrar”) and (ii) an office or agency where Notes may be presented for payment to a Paying Agent. The Registrar shall keep a register of the Notes and of their transfer and

The Issuers shall notify the Trustee in writing, and the Trustee shall notify the Holders, of the name and address of any Agent not a party to
this Indenture. The Issuers shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain a Registrar or Paying Agent, or fail to give the foregoing notice, the Trustee

Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or interest on the Notes, and shall notify the Trustee of
any Default by the Issuers in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay to the Trustee all money held by it in trust for the benefit of the Holders or the Trustee. The Issuers at any
time may require a Paying Agent to pay all money held by it in trust for the benefit of the Holders or the Trustee to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuers or a Subsidiary) shall have no further
liability for such money. If the Issuers or any of their Restricted Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon the occurrence of
any of the events specified in Section 6.1, the Trustee shall serve as Paying Agent for the Notes. 

  
 37 

 SECTION 2.5. 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 all Holders. If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee at least seven (7) Business Days before each interest payment

whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any Agent or their respective agents from giving effect to any written certification, proxy or other authorization furnished by the Depositary or

stamp or transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Section 2.10, Section 2.16, Section 3.6, Section 4.10, Section 4.14 and Section 9.4 hereof). 

(3) All Global Notes and certificated Notes issued upon any registration of transfer or exchange of Global Notes or
certificated Notes shall be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes (or interests therein) or certificated Notes surrendered upon such registration
of transfer or exchange. 
 (4) The Registrar is not required (A) to issue, to register the transfer of or to exchange
Notes during a period beginning at the opening of business fifteen (15) days before the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to

none of the Trustee, any Agent, or the Issuers shall be affected by notice to the contrary.

Trustee to comply with any applicable tax reporting obligations, including any cost basis reporting obligations under Section 6045 of the Internal Revenue Code of 1986, as amended. The Trustee may rely on information provided to it and shall
have no responsibility to verify or ensure the accuracy of such information. In connection with any proposed exchange of a certificated Note for a Global Note, the Issuers or the Depositary shall be required to provide or cause to be provided to the
Trustee all information available to the Issuers or the Depositary, as applicable, that is necessary to allow the Trustee to comply with any applicable tax reporting obligations, including any cost basis reporting obligations under Section 6045
of the Internal Revenue Code of 1986, as amended. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9, a Note does not cease to be outstanding because the Issuers or an Affiliate of an Issuer holds the Note.

 If a Note is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that
the replaced Note is held by a protected purchaser. 
 If the Paying Agent (other than an Issuer, a Subsidiary or an Affiliate of any
thereof) holds, on or after the maturity date, any redemption date or date for purchase of the Notes pursuant to an offer to purchase, money sufficient to pay the amounts under the Notes payable on such date, then on and after that date such Notes
payable on such date shall be deemed to be no longer outstanding and shall cease to accrue interest. 
 SECTION 2.9. Treasury
Notes. In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by any Issuer or by any Affiliate of any Issuer shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes of which a Responsible Officer of the Trustee has written notice as being so
owned shall be so disregarded. Notwithstanding the foregoing, Notes that are to be acquired by an Issuer or an Affiliate of an Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until
legal title to such Notes passes to such entity. 
 SECTION 2.10. Temporary Notes. Until certificated Notes are ready for
delivery, the Issuers may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuers signed by one Officer of each Issuer. Temporary Notes shall be substantially in the form of certificated Notes but may have
variations that the Issuers consider appropriate for temporary Notes. Without unreasonable delay, the Issuers shall prepare and the Trustee shall upon receipt of a written order of the Issuers signed by one Officer, authenticate certificated Notes
in certificate form in exchange for temporary Notes. 
 Holders of temporary Notes shall be entitled to all of the benefits of this
Indenture. 
 SECTION 2.11. Cancellation. The Issuers at any time may deliver to the Trustee for cancellation any Notes
previously authenticated and delivered hereunder or which any of the Issuers may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer,
exchange or payment, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation.
Subject to Section 2.7, the Issuers may not 

  
 41 

 
issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in
accordance with its customary practice, and certification of their disposal delivered to any of the Issuers upon their written request therefor. 

SECTION 2.12. Defaulted Interest. If the Issuers default in a payment of interest on the Notes, they shall pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be the earliest practicable date but in all events at least
five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1. The Issuers shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter
notify the Trustee of any such date. At least fifteen (15) days before the special record date, the Issuers (or the Trustee, in the name and at the expense of the Issuers) shall mail or cause to be mailed to Holders a notice that states the
special record date, the related payment date and the amount of such interest to be paid. The Trustee will have no duty whatsoever to determine whether any defaulted interest is payable or the amount thereof. 

SECTION 2.13. Computation of Interest. Interest on the Notes shall be computed on the basis of
a 360-day year comprised of twelve 30-day months. 

SECTION 2.14. CUSIP Number. The Issuers in issuing the Notes may use a “CUSIP” number, and if it does so,
the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed
in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuers shall promptly notify the Trustee in writing of any change in any CUSIP number. 

SECTION 2.15. Special Transfer Provisions. Each Note issued pursuant to an exemption from registration under the Securities Act
(other than in reliance on Regulation S) will constitute a Transfer Restricted Note and be required to bear the Restricted Notes Legend until the date that is one year after the later of the date of original issue and the last date on which an
Issuer or any affiliate (within the meaning of Rule 405 under the Securities Act) of an Issuer was the owner of such Notes (or any predecessor thereto), unless and until such Transfer Restricted Note is transferred or exchanged pursuant to an
effective registration statement under the Securities Act. 
 (a) Transfers to QIBs. The following provisions shall
apply with respect to the registration of any proposed transfer of a Note issued in reliance on Regulation S to a QIB: 

(i) The Registrar shall register the transfer of a Note issued in reliance on Regulation S by a Holder to a QIB if such
transfer is being made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in
Exhibit D from the proposed transferor; provided that the letter required by paragraph 2.5(a)(i)(b) shall only be required 

  
 42 

 
on or prior to the 40th day after the later of the commencement of the offering of such Note and the issue date of such Note (such period through and including such 40th day, the
“Restricted Period”). The Issuers shall provide written notice to the Trustee of the date that constitutes the final day of the Restricted Period in respect of any Notes issued in reliance on Regulation S;
provided, however, that no such notice shall be required with respect to any Initial Notes issued in reliance on Regulation S and May 28, 2018 shall constitute the final day of the Restricted Period for such Initial Notes.

 (ii) If the proposed transferee is a Participant and the Note to be transferred consists of an interest in the
Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph (i) above and (y) instructions given in accordance with the Depositary’s and the Registrar’s procedures therefor, the
Registrar shall reflect on its books and records the date and an increase in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the beneficial interest in the Regulation S Global Note 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 such Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in such
Regulation S Global Note to be so transferred. 
 (b) Transfers Pursuant to Regulation S. The
following provisions shall apply with respect to registration of any proposed transfer of a Transfer Restricted Note pursuant to Regulation S: 

(i) The Registrar shall register any proposed transfer of a Transfer Restricted Note by a Holder pursuant to Regulation S
upon receipt of (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit E hereto from the proposed transferor. 

(ii) If the proposed transferee is a Participant and the Transfer Restricted Note to be transferred consists of an interest in
the Rule 144A Global Note upon receipt by the Registrar of (x) the letter, if any, required by paragraph (i) above and (y) instructions in accordance with the Depositary’s and the Registrar’s procedures therefor, the
Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in the Rule 144A Global Note to be
transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the beneficial interest in such
Rule 144A Global Note to be transferred. 
 (c) In the event that a Global Note is exchanged for Notes in certificated,
registered form pursuant to Section 2.6, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of clauses (a) and (b) above (including the certification requirements
intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Issuers and notified to the Trustee in writing. 

  
 43 

 (d) Restricted Notes Legend. Upon the transfer, exchange or replacement of
Notes not bearing the Restricted Notes Legend, the Registrar shall deliver Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, the Registrar shall deliver only
Notes that bear the Restricted Notes Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that neither such legend nor the related restrictions on transfer are required in order
to maintain compliance with the provisions of the Securities Act. 
 (e) Regulation S Legend. Upon
the transfer, exchange or replacement of Notes not bearing the Regulation S Legend, the Registrar shall deliver Notes that do not bear the Regulation S Legend. Upon the transfer, exchange or replacement of Notes bearing the
Regulation S Legend, the Registrar shall deliver only Notes that bear the Regulation S Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that neither such legend
nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. 

(f) General. By its acceptance of any Note bearing the Restricted Notes Legend or the Regulation S Legend, as
applicable, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend or the Regulation S Legend, as applicable, and agrees that it shall transfer such Note
only as provided in this Indenture. A transfer of a beneficial interest in a Global Note that does not involve an exchange of such interest for a certificated Note or a beneficial interest in another Global Note shall be subject to compliance with
applicable law and the applicable procedures of the Depositary but is not subject to any procedure required by this Indenture. 
 In
connection with any proposed transfer pursuant to Regulation S or pursuant to any other available exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A), the Issuers may require the delivery of an
Opinion of Counsel, other certifications or other information satisfactory to the Issuers. 
 The Registrar shall retain copies of all
letters, notices and other written communications received pursuant to this Section 2.15. 
 SECTION 2.16. Issuance of
Additional Notes. The Issuers shall be entitled to issue Additional Notes in an unlimited aggregate principal amount under this Indenture that shall have identical terms as the Initial Notes, other than with respect to the date of issuance,
issue price, amount of interest payable on the first interest payment date applicable thereto and transfer restrictions; provided that such issuance is not prohibited by the terms of this Indenture, including Section 4.9 and
Section 4.12, provided further that Additional Notes will not be issued with the same CUSIP, if any, as any Notes then existing unless such Additional Notes are fungible with such Notes then existing for U.S. federal income tax purposes.
The Initial Notes and any Additional Notes shall be treated as a single class for all purposes under this Indenture. 

  
 44 

 With respect to any Additional Notes, each Issuer shall set forth in a resolution of its Board of
Directors and in an Officers’ Certificate, a copy of each of 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; 

(2) the issue price, the issue date, the CUSIP number of such Additional Notes, the first interest payment date and the amount
of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue; 

(3) whether such Additional Notes shall be Transfer Restricted Notes; and 

(4) that such issuance is not prohibited by this Indenture. 

The Trustee shall, upon receipt of the resolution of each Issuer’s Board of Directors and Officers’ Certificate, authenticate the
Additional Notes in accordance with the provisions of Section 2.2 of this Indenture. 
 SECTION 2.17. Payment of Additional
Amounts. 
 (1) All payments made by or on behalf of the Issuers under or with respect to the Notes or by or on behalf of any Guarantor
under or with respect to its Guarantee, will be made without withholding or deduction for or on account of any Taxes imposed or levied by or on behalf of any Panamanian taxing authority or any political subdivision or any authority or agency therein
or thereof having power to tax, or any other jurisdiction in which either Issuer 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 (including, without limitation, the jurisdiction of each paying agent) (each, a “Specified Tax Jurisdiction”), unless required by law or regulation of any such taxing authority.
If an Issuer or a Guarantor is obligated to withhold or deduct any amount for, or on account of Taxes imposed or levied by or on behalf of any Specified Tax Jurisdiction from any payment made under or with respect to the Notes, or any Guarantee,
including, without limitation, payments of principal, redemption price, purchase price, interest or premium, such Issuer or such Guarantor will: 

(a) subject to the limitations below, pay such additional amounts (“Additional Amounts”) as may be necessary
so that the net amount received in respect of such payments (including Additional Amounts) after such withholding or deduction will not be less than the amount that would have been received in respect of such payments if such Taxes had not been
withheld or deducted; 
 (b) make all withholdings and deductions required by applicable law and remit the full amount
deducted or withheld to the relevant tax authority in accordance with applicable law; 

  
 45 

 (c) furnish to the Trustee for the benefit of the beneficial owners of the Notes,
within 60 days after the date payment of any Taxes is due pursuant to applicable law, certified copies of an official receipt of the relevant government authorities for all amounts deducted or withheld pursuant to applicable law, or if such receipts
are not readily obtainable without significant expense (as reasonably determined by the Issuers), other evidence of payment by such Issuer or such Guarantor of those Taxes reasonably satisfactory to the Trustee which the Trustee will make available
to the beneficial owners of Notes upon reasonable request; and 
 (d) at least 15 days prior to each date on which
any Additional Amounts are payable, deliver to the Trustee an Officers’ Certificate setting forth the calculation of the Additional Amounts to be paid and such other information as the Trustee may request to enable the Trustee to pay such
Additional Amounts on the payment date. The Trustee shall not be required to determine whether such payments are necessary and shall be entitled to rely solely on such Officers’ Certificate as conclusive proof with respect thereto. 

(2) Notwithstanding the foregoing, no Issuer nor any Guarantor will pay Additional Amounts with respect to a payment made to any Holder or
beneficial owner of a Note: 
 (a) which is subject to such taxes by reason of the Holder or the beneficial owner being a
resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in, or otherwise having some present or former connection with the relevant Specified Tax Jurisdiction otherwise than by
the mere acquisition, holding or disposition of the Notes, or the enforcement of rights or the receipt of payments under or in respect of any Note or any Guarantee; 

(b) for or on account of any taxes imposed or deducted or withheld by reason of the failure of the Holder or beneficial owner
of the Notes to complete, execute and deliver to an Issuer or a Guarantor, as the case may be, any customary form or document, to the extent applicable to such Holder or beneficial owner, and to the extent such Holder or beneficial owner is legally
entitled to do so, that is required by law (including any applicable tax treaty) or by reason of administration of such law, and which is reasonably requested in writing by such Issuer or such Guarantor at least 60 days before any such withholding
or deduction would be payable to be delivered to such Issuer or such Guarantor in order to enable such Issuer or such Guarantor to make payments on the Notes or pursuant to any Guarantee, as the case may be, without deduction or withholding for
taxes, or with deduction or withholding of a lesser amount; 
 (c) for or on account of any estate, inheritance, gift, sales,
transfer, capital gains, excise, personal property or similar Tax; 
 (d) for or on account of any Tax that is payable
otherwise than by withholding from payments under or with respect to the Notes or the Guarantees; 
 (e) where the payment
could have been made without any deduction or withholding if the beneficiary of the payment had presented the Note for payment within 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; 

  
 46 

 (f) if the Holder is a fiduciary, partnership or person other than the sole
beneficial owner of that payment, to the extent that such payment would be required to be included in income under the laws of the relevant taxing jurisdiction for tax purposes, of a beneficiary or settler with respect to such fiduciary, a member of
such partnership or a beneficial owner who, in each case, would not have been entitled to such Additional Amounts had such beneficiary, settler, partner or beneficial owner been the Holder thereof; 

(g) any withholding tax imposed by the United States or a political subdivision thereof; or 

(h) any combination of the instances described in the foregoing clauses (a) through (g). 

(3) Any reference in this Indenture or the Notes to the payment of principal, premium, if any, interest, purchase price, redemption price or
any other amount payable under or with respect to any Note, will be deemed to include the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. The Issuers’ and
the Guarantors’ obligation to make payments of Additional Amounts will survive any termination of this Indenture or the defeasance of any rights hereunder or any transfer by a Holder or beneficial owner of its Notes. 

(4) The Issuers and the Guarantors will promptly pay and indemnify the Holders and beneficial owners of the Notes for any present or future
stamp, issue, registration, transfer, documentation, court or any other excise or property Taxes, charges or similar levies (including interest and penalties with respect thereto) that arise in a Specified Tax Jurisdiction from the execution,
delivery, enforcement or registration of each Note, any Guarantee or any other document or instrument referred to herein or therein or the receipt of any payments with respect thereto (limited, solely in the case of taxes attributable to the receipt
of any payments with respect thereto, to any such taxes imposed in a relevant Tax Jurisdiction that are not excluded under clauses 2(a) through (c) and 2(e) through (h) of this Section 2.17 or any combination thereof). 

ARTICLE III 
 REDEMPTION AND
PREPAYMENT 
 SECTION 3.1. Notices to Trustee. If the Issuers elect to redeem Notes pursuant to the optional redemption
provisions of Section 3.7, they shall furnish to the Trustee, at least three (3) Business Days (or such shorter period as is acceptable to the Trustee) prior to the giving of notice of redemption, an Officers’ Certificate setting
forth the (i) section of this Indenture pursuant to which the redemption shall occur, (ii) redemption date, (iii) principal amount of Notes to be redeemed and (iv) redemption price (provided that, with respect to any
redemption pursuant to Section 3.7(a), the redemption price need only be included in such notice to the extent the redemption price has been determined at the time of such notice (and if not so determined at such time, such notice shall then
include the manner in which the redemption price will be calculated)). 

  
 47 

 If the Issuers are required to make an offer to purchase Notes pursuant to Section 4.10 or
Section 4.14, they shall furnish to the Trustee, at least three (3) Business Days (or such shorter period as is acceptable to the Trustee) prior to the giving of notice of the offer to purchase, an Officers’ Certificate setting forth
the (i) section of this Indenture pursuant to which the offer to purchase shall occur, (ii) terms of the offer, (iii) principal amount of Notes to be purchased, (iv) purchase price and (v) purchase date and further setting
forth a statement to the effect that (a) the Issuers or one of their respective Restricted Subsidiaries has effected an Asset Sale and there are Excess Proceeds aggregating an amount equal to or more than $25.0 million or (b) a Change
of Control has occurred, as applicable. 
 The Issuers will also provide the Trustee with any additional information that the Trustee
reasonably requests in connection with any redemption or offer. 
 SECTION 3.2. Selection of Notes to Be Redeemed. If less than
all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so
listed, on a pro rata basis (or, in the case of such Notes issued in global form, based on a method DTC or its nominee or successor may require); provided, however that no Notes of $2,000 in original principal amount or less
shall be redeemed in part. In addition, if a partial redemption is made pursuant to Section 3.7(d), selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro
rata basis as is practicable (or, in the case of such Notes issued in global form, based on a method DTC or its nominee or successor may require), unless that method is otherwise prohibited. 

On and after the redemption date, interest will cease to accrue on Notes or portions of them called for redemption so long as the Issuers have
complied with Section 3.5 in connection with such redemption. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption as long as the Issuers have deposited with the Paying Agent funds in
satisfaction of the applicable redemption price pursuant to this Indenture and shall promptly notify the Issuers in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to $1,000 or any integral
multiples of $1,000 thereof) of the principal of the Notes that have denominations larger than $2,000. 
 SECTION 3.3. Notice of
Redemption. Subject to the provisions of Section 4.10 and Section 4.14, the Issuers shall deliver or cause to be delivered in accordance with Section 11.1, a notice of redemption to each Holder whose Notes are to be redeemed (with
a copy to the Trustee), at least fifteen (15) days but not more than sixty (60) days before a redemption date (except that notices may be delivered more than sixty (60) days before a redemption date if the notice is issued in
accordance with Section 8.8). 

  
 48 

 The notice shall identify the Notes (including CUSIP numbers) to be redeemed and shall state:

 (1) the redemption date; 

(2) the redemption price; provided that, with respect to any redemption pursuant to Section 3.7(a), the redemption
price need only be included in the notice of redemption to the extent the redemption price has been determined at the time of such notice of redemption (and if not so determined at such time, the notice of redemption shall then include the manner in
which the redemption price will be calculated); 
 (3) if any Note is being redeemed in part, the portion of the principal
amount of such Notes to be redeemed and that, after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note (or appropriate
adjustments to the amount and beneficial interests in a Global Note will be made, as appropriate); 
 (4) the name and
address of the Trustee; 
 (5) that Notes called for redemption must be surrendered to the Trustee to collect the redemption
price; 
 (6) that, unless an Issuer defaults in making such redemption payment, interest, if any, on Notes called for
redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph of the Notes and/or Section of this
Indenture pursuant to which the Notes called for redemption are being redeemed; 
 (8) that no representation is made as to
the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and 
 (9) if
applicable, any conditions to such redemption. 
 At the Issuers’ written request, the Trustee shall give the notice of redemption in
the Issuers’ names and at the Issuers’ expense; provided, however, that the Issuers shall have delivered to the Trustee, at least three (3) Business Days prior to the giving of notice of redemption (or such shorter
period as is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notice as provided in the preceding paragraph. The notice delivered in the
manner herein provided shall be deemed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note shall not affect the validity of the
proceeding for the redemption of any other Note. 
 SECTION 3.4. Effect of Notice of Redemption. Except with respect to notices
of redemption given in accordance with Section 3.7(e), once notice of redemption is delivered in accordance with Section 3.3, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price
plus accrued and unpaid interest to (but excluding) such date unless the redemption is subject to a condition precedent that has not been satisfied or waived. Notice of redemption may, at the Issuers’ discretion, be subject to one or more
conditions precedent as set forth in Section 3.7(g). 

  
 49 

 SECTION 3.5. Deposit of Redemption Price. On or before 10:00 a.m. (New York City
time) on the Business Day prior to each redemption date or the date on which Notes must be accepted for purchase pursuant to Section 4.10 or Section 4.14, the Issuers shall deposit with the Trustee or with the Paying Agent (other than the
Issuers or an Affiliate of an Issuer) money sufficient to pay the redemption price of and accrued and unpaid interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the
Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption price of (including any applicable premium), and accrued interest, if any, on, all Notes to be redeemed or
purchased. 
 If Notes called for redemption or tendered in a Net Proceeds Offer or Change of Control Offer are paid or if the Issuers have
deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption or purchase date, interest, if
any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in a Net Proceeds Offer or Change of Control Offer (regardless of whether certificates for such securities are actually
surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the
close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal
from the redemption or purchase 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 4.1. 

SECTION 3.6. Notes Redeemed in Part. Upon surrender and cancellation of a Note that is redeemed in part, the Issuers shall issue
and, upon the written request of an Officer of each Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed portion of the Note surrendered and canceled; provided
that each such new Note will be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof. 

SECTION 3.7. Optional Redemption. 

(a) The Notes may be redeemed, in whole or in part, at any time prior to May 1, 2021 at the option of the Issuers upon notice in
accordance with the provisions of Section 3.3, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium (calculated by the Issuers as certified in an Officers’ Certificate to the
Trustee, showing the calculation of such in reasonable detail) as of, and accrued and unpaid interest, if any, to (but excluding), the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive
interest due on the relevant interest payment date). 
 (b) The Notes are subject to redemption, at the option of the Issuers, in whole or
in part, at any time or from time to time on or after May 1, 2021, upon notice in accordance with the provisions of Section 3.3, at the following redemption prices (expressed as percentages of the principal amount to be redeemed) set forth
below, plus accrued and unpaid interest, if any, on the 

  
 50 

 
Notes redeemed to (but excluding) the applicable redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period beginning May 1 of the years indicated below: 
  

					
	 Year
	  	Redemption Price	 
	 2021
	  	 	105.313	% 
	 2022
	  	 	102.656	% 
	 2023 and thereafter
	  	 	100.000	% 

 (c) The Issuers may acquire Notes by means other than a redemption, whether pursuant to a tender offer, open
market purchase, negotiated transaction or otherwise, in accordance with applicable securities laws. 
 (d) At any time or from time to time
prior to May 1, 2021, the Issuers, at their option, may on any one or more occasions, upon notice in accordance with the provisions of Section 3.3, redeem up to 35.0% of the aggregate principal amount of the outstanding Notes issued
under this Indenture (calculated after giving effect to any issuance of Additional Notes), in an amount not greater than the net cash proceeds of one or more Qualified Equity Offerings of the Company (which have not been applied to permanently repay
other Indebtedness) at a redemption price equal to 110.625% of the principal amount of such Notes redeemed, plus accrued and unpaid interest thereon, if any, to (but excluding) the applicable date of redemption (subject to the right of Holders
of record on the relevant record date to receive interest due on the relevant interest payment date); provided that: 

(1) at least 65.0% of the aggregate principal amount of Notes being redeemed issued under this Indenture on the Issue Date
remains outstanding immediately after giving effect to any such redemption; and 
 (2) each such redemption occurs not more
than 180 days after the date of the closing of any such Qualified Equity Offering. 
 (e) If an Issuer or a Guarantor becomes
obligated to pay any Additional Amounts as a result of a change in the laws or regulations of any Specified Tax Jurisdiction, or a change in any official written position of any Specified Tax Jurisdiction regarding the application or interpretation
thereof (including a holding by a court of competent jurisdiction), which is first publicly announced and becomes effective on or after the Issue Date (or, if later, on or after the date the relevant Specified Tax Jurisdiction first becomes a
Specified Tax Jurisdiction) and such Additional Amounts cannot (as certified in an Officers’ Certificate to the Trustee) be avoided by the use of reasonable measures available to the Issuers (including changing the jurisdiction of a paying
agent or making the relevant payment by or through a different Issuer or Guarantor), then the Issuers may, at their option, redeem the Notes, in whole but not in part, upon notice in accordance with the provisions of Section 3.3 (such notice to
be provided not less than 30 nor more than 90 days before the next date on which the Issuers would be obligated to pay Additional Amounts), at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, to (but excluding) the redemption date and all Additional Amounts, if any, then due or that will otherwise become due on the redemption date as a result of the redemption (subject to the right of Holders of record on the relevant
record date to receive 

  
 51 

 
interest due on an interest payment date that is on or prior to the redemption date and Additional Amounts (if any) in respect thereof). Notice of the Issuers’ intent to redeem the Notes
shall not be effective until such time as it delivers to the Trustee an Opinion of Counsel stating that the Issues are obligated to pay Additional Amounts because of an amendment to or change in law or regulation or official position as described in
this paragraph. 
 (f) Any redemption pursuant to this Section 3.7 shall be made in accordance with the applicable provisions of
Sections 3.1 through 3.6. 
 (g) Any redemption and any notice of any redemption (other than, in each case, a redemption under
Section 3.7(e)) may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a Qualified Equity Offering, other offering, issuance of Indebtedness or other corporate
transaction or event. Notice of any redemption in respect thereof may be given prior to the completion thereof and may be partial as a result of only some of the conditions being satisfied. The Issuers will provide the Trustee with written notice of
the satisfaction (or waiver) of such conditions, the delay of such redemption or the rescission of such notice of redemption in the same manner (other than any minimum notice period) that the related notice of redemption was given to the Trustee,
and the Trustee will send a copy of such notice to the Trustee to the Holders in the same manner that the related notice of redemption was given to such Holders. 

SECTION 3.8. Mandatory Redemption. Except for a Special Mandatory Redemption pursuant to Section 3.9 hereof, the Issuers are
not required to make mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Issuers may be required to offer to purchase the Notes as described in Sections 4.10 and 4.14. 

SECTION 3.9. Escrow of Proceeds; Special Mandatory Redemption.

in writing that the Combination will not be consummated on or prior to the date that is two Business Days prior to the Outside Date, (2) the Initial Co-Issuers shall have notified the Trustee and the
Escrow Agent in writing that the Escrow Conditions (as defined below) are determined by the Initial Co-Issuers to be incapable of being satisfied on or prior to the Outside Date, or (3) the Initial Co-Issuers shall have notified the Trustee and the Escrow Agent in writing that the Combination will not be consummated or that the Combination Agreement has been terminated (any such event, a “Special
Mandatory Redemption Event”), the Escrow Agent shall, without the requirement of notice to or action by the Initial Co-Issuers, the Trustee or any other Person, release and deliver the Escrowed Funds
to the Trustee not later than the third Business Day succeeding the date of any such notice (any such notice being referred to herein as “Special Redemption Notice”), and the Trustee will apply such Escrowed Funds to redeem all of
the Notes (the “Special Mandatory Redemption”) at a price equal to 100.0% of the initial issue price of such Note plus accrued and unpaid interest thereon to (but not including) the date fixed for such redemption (the
“Special Mandatory Redemption Date”) as specified in the Special Redemption Notice, which date may be no later than one Business Day after the Outside Date. Concurrently with the delivery of the Special Redemption Notice, the
Initial Co-Issuers will instruct the Trustee to, at the Initial Co-Issuers’ expense, send (by first-class mail to each Holder’s registered address or otherwise
in accordance with the procedures of DTC) a notice that a Special Mandatory Redemption will occur on the Special Mandatory Redemption Date. Upon the consummation of the Combination, the foregoing provisions regarding the Special Mandatory Redemption
will cease to apply.

 (b) On the Issue Date, the Initial Co-Issuers will enter
into an agreement with the Escrow Agent and the Trustee (the “Escrow Agreement”) pursuant to which the Initial Purchasers and the Initial Co-Issuers (or the Company or any of its Subsidiaries)
will deposit the Escrowed Funds into the Escrow Account. The Initial Co-Issuers will only be entitled to direct the Escrow Agent to release the Escrowed Funds in accordance with the terms of the Escrow
Agreement. Pursuant to the Escrow Agreement, the Escrow Agent will release the Escrowed Funds (the “Release”) at the written direction of the Initial Co-Issuers, with a copy to the Trustee, on
the date upon which the satisfaction of certain conditions occurs (such date, the “Escrow Release Date”), including the delivery by the Initial Co-Issuers, with a copy to the Trustee, of an
Officers’ Certificate of the Initial Co-Issuers addressed to the Escrow Agent certifying that the following conditions have been or, substantially concurrently with the release of the Escrow Funds, shall
be, satisfied (the “Escrow Conditions”): 
 (1) (a) all conditions precedent in the Combination Agreement
necessary to the consummation of the Combination will have been satisfied or waived in accordance with the terms of the Combination Agreement (other than those conditions that by their terms will be satisfied substantially concurrently with the
consummation of the Combination), (b) the availability of sufficient funds under the Credit Agreement (when taken together with the Escrowed Funds and funds held by the Company and its Subsidiaries) to complete the Transactions (other than the
Release) and (c) the Escrowed Funds will be used to consummate the Transactions; provided that the terms of the Combination Agreement shall not have been amended, modified, consented to or waived after the Issue Date and on or prior to the
Escrow Release Date except for such amendments, consents or waivers that are not, when taken as a whole, materially adverse to the Holders; and 

(2) The Company, the Post-Merger Co-Issuers and the Restricted Subsidiaries required to
become Guarantors hereunder as of the Escrow Release Date shall have, by one or more supplemental indentures or joinders, as applicable, effective upon the Escrow Release Date, become, or substantially concurrently with the Escrow Release shall
become, parties to this Indenture and the Purchase Agreement. 
 (c) To secure the obligations with respect to the Notes, the Initial Co-Issuers grant to the Trustee, for the benefit of the Holders, a first-priority security interest (other than any Liens in favor of the Escrow Agent that arise by operation of law or as a result of the account
documentation among the Escrow Agent and the Initial Co-Issuers) in the Escrow Account and the Escrowed Funds until the Escrow Release Date, on which date such Liens shall automatically terminate with no
further action. 
 (d) Notwithstanding anything to the contrary in this Indenture, any redemption pursuant to this Section 3.9 shall
not be subject to the provisions of Sections 3.1 through 3.7 hereof. 

  
 53 

 (e) The Trustee will pay to the Issuers any Escrowed Property remaining after the Special
Mandatory Redemption and payment of any amounts due to the Trustee or the Escrow Agent hereunder and under the Escrow Agreement. 
 (f) The
Trustee is authorized to enter into and perform its obligations under the Escrow Agreement. 
 The Escrow Agent will promptly invest the
Escrowed Funds in such Eligible Escrow Investments as either Initial Co-Issuer will from time to time direct in writing. In the absence of such direction, the Escrowed Funds will be left uninvested.

 SECTION 4.3. Provision of Financial Information. 

Whether or not required by the SEC, so long as any Notes are outstanding, from and after the Escrow Release Date, the Company will furnish to
the Trustee and the Holders, or, to the extent permitted by the SEC, file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system) (“EDGAR”) within the
time periods specified in the SEC’s rules and regulations: 
 (1) all quarterly and annual reports that would be
required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such reports; and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if
the Company were required to file such reports. 
 If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, and
such Unrestricted Subsidiaries, individually or taken together, would constitute a Significant Subsidiary of the Company, then the quarterly and annual financial information required by this Section 4.3 will include a reasonably detailed
presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the
Company and its Restricted Subsidiaries excluding the Unrestricted Subsidiaries. 
 For so long as any Notes remain outstanding and are
“restricted securities” within the meaning of Rule 144(A)(3), and the Company and the Guarantors are not required to file the reports required by this Section 4.3 with the SEC, the Company shall furnish to the Holders and to
securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

The Company will be deemed to have furnished the reports required to be furnished to the Trustee and the Holders pursuant to this
Section 4.3 if the Company has filed such reports with the SEC using the EDGAR filing system or if it has made such reports publicly available on its website. 

In addition, the Company will: 

(1) hold a quarterly conference call to discuss the information contained in the annual and quarterly reports not later than
ten Business Days from the time the Company furnishes the reports to the Trustee pursuant to the first paragraph of this covenant (it being understood that customary earnings conference calls available to the public shall satisfy this requirement);
and 
 (2) no fewer than three Business Days prior to the date of the conference call required to be held in accordance with
clause (1) above, issue a press release to customary U.S. wire services announcing the time and date of such conference call and providing the contact information of an individual at the Company that can provide information on how to access
such conference call. 

  
 55 

 Delivery of reports, information and documents to the Trustee is for informational purposes only
and its receipt of such reports, information and documents shall not constitute constructive knowledge or notice of any information contained therein or determinable from information contained therein, including either Issuer’s, any
Guarantor’s or any other person’s compliance with any of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 

The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, either Issuer’s, any Guarantor’s or
any other person’s compliance with the covenants described herein, or to determine whether any reports, information or other documents have been posted on a website or filed with the SEC under this Indenture or to participate in any conference
calls. 
 In the event that: 

(i) the rules and regulations of the SEC permit the Company and any direct or indirect parent company of the Company to report
at such parent entity’s level on a consolidated basis and such parent entity of the Company is not engaged in any business in any material respect other than incidental to its ownership, directly or indirectly, of the Voting Stock of the
Company, or 
 (ii) any direct or indirect parent of the Company becomes a Guarantor, 

such consolidated reporting at such parent entity’s level in a manner consistent with that described in this covenant for the Company will satisfy this
covenant; provided that such financial information is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such direct or indirect parent and any of its Subsidiaries
other than the Company and its Subsidiaries, on the one hand, and the information relating to the Company and its Subsidiaries on a stand-alone basis, on the other hand. 

The Company shall notify the Trustee in writing if the Company is not permitted by the SEC to file, or has not filed, electronically with the
SEC through EDGAR (or any successor system) the information and reports referred to in clauses (1) and (2) of this Section 4.3. The Trustee shall have no obligation to determine if and when the Issuer’s information is available
on the SEC’s website. 
 SECTION 4.4. Compliance Certificate. The Company shall deliver to the Trustee,
within 90 days after the end of each fiscal year beginning with the fiscal year ending December 31, 2018, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding
fiscal year has been made under the supervision of the signing Officers with a view to determining whether each has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing
such certificate, that, to his or her knowledge, each entity has kept, observed, performed and fulfilled in all material respects each and every covenant contained in this Indenture and is not in default in the performance or observance in any
material respect of any of the terms, provisions and conditions of this Indenture (or, if a Default shall have occurred, 

  
 56 

 
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 that, to his or her
knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and what action
the Company is taking or proposes to take with respect thereto. 
 The Company shall, so long as any of the Notes are outstanding, deliver
to the Trustee, within 30 days after any Officer becomes aware of any Default, an Officers’ Certificate specifying such Default and what action the Company is taking or proposes to take with respect thereto. 

SECTION 4.5. Taxes. The Issuers shall pay, and shall cause each of their respective 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 and with respect to which appropriate reserves have been taken in accordance with GAAP or where the failure to effect such
payment is not adverse in any material respect to the Holders. 
 SECTION 4.6. Stay, Extension and Usury Laws. The Issuers and
each of the Guarantors covenants (to the extent that it may lawfully do so) that they 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 the Issuers and each of 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 4.7. Limitation on Restricted Payments. 

(a) From and after the Escrow Release Date, the Company will not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
make any Restricted Payment if at the time of such Restricted Payment: 
 (1) a Default shall have occurred and be continuing
or shall occur as a consequence thereof; 
 (2) the Company is not able to incur at least $1.00 of additional Indebtedness
pursuant to the Coverage Ratio Exception; or 
 (3) the amount of such Restricted Payment, when added to the aggregate amount

Equity Interests, plus 
 (D) in the case of the disposition or repayment of or return on any Investment that was treated as
a Restricted Payment made by the Company after the Escrow Release Date, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) 100.0% of the aggregate amount received by the Company or any
Restricted Subsidiary in cash or other property (valued at the Fair Market Value thereof) as the return of capital with respect to such Investment and (ii) the amount of such Investment that was treated as a Restricted Payment, plus

provided that, prior to or concurrently with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Change of Control Offer or Net Proceeds Offer, as applicable, as provided in such
covenant with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Change of Control Offer or Net Proceeds Offer;

Restricted Payment, the Total Net Leverage Ratio would be less than 2.25 to 1.0; and 
 (12) any Restricted Payment made for
the purposes of consummating the Transactions including those described in the Offering Memorandum under “Summary—The Combination Transactions—Payments in Connection with the Combination,”

Restricted Payments Basket to the extent of such payment. 
 For the purposes of determining compliance with any U.S. dollar
denominated restriction on Restricted Payments denominated in a foreign currency, the U.S. dollar equivalent amount of such Restricted Payment shall be calculated based on the relevant currency exchange rate in effect on the date that such
Restricted Payment was made. 

  
 60 

 As of the Escrow Release Date, all of the Company’s Subsidiaries will be Restricted
Subsidiaries, except Boudin Insurance Company, Ltd., a Bermuda company, and McDermott (DLV 2000) Chartering, Inc., a Panamanian corporation. The Company will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to
Section 4.18. For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be
deemed to be Restricted Payments or Permitted Investments, as determined by the Company, in an amount determined as set forth in the definition of “Investment.” Such designation will be permitted only if a Restricted Payment and Permitted
Investments, as applicable, in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 

SECTION 4.8. Limitations on Dividend and Other Restrictions Affecting Restricted Subsidiaries. From and after the Escrow Release
Date, the Company will not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any
Restricted Subsidiary to: 
 (a) pay dividends or make any other distributions on or in respect of its Equity Interests to the Company or any
of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to
dividends or liquidating distributions being paid on other types of Equity Interests shall not be deemed a restriction on the ability to make distributions on Equity Interests); 

(b) make loans or advances, or pay any Indebtedness or other obligation owed, to the Company or any other Restricted Subsidiary (it being
understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness or obligations incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to
make loans or advances); or 
 (c) transfer any of its property or assets to the Company or any other Restricted Subsidiary (it being
understood that such transfers shall not include any type of transfer described in clause (a) or (b) above);

 61 

 (4) any agreement or other instrument of a Person acquired by the Company or any of its
Restricted Subsidiaries in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and
its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired (including after acquired property); 
 (5) any
amendment, restatement, modification, renewal, supplement, refunding, replacement or refinancing of an agreement referred to in clauses (1), (2), (3), (4), (5) or (11); provided, however, that such amendments, restatements,
modifications, renewals, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company, not materially more restrictive, taken as a whole, than the encumbrances and restrictions contained in the agreements
referred to in such clauses on the Escrow Release Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable; 

(6) encumbrances or restrictions existing under or by reason of applicable law, regulation, order, approval, license or similar restriction;

 (7) non-assignment provisions of any contract or any lease entered into in the ordinary course of
business; 
 (8) in the case of clause (c) above, Liens permitted to be incurred under the provisions of Section 4.12 that limit
the right of the debtor to dispose of the assets securing such Indebtedness; 
 (9) encumbrances or restrictions arising or agreed to in the
ordinary course of business (i) that restrict in a customary manner the chartering, subletting, assignment or transfer of any property or asset that is subject to a lease or license or (ii) not relating to Indebtedness and that do not,
individually or in the aggregate, detract from the value of property or assets of the Company or the Restricted Subsidiaries in any manner material to the Company and the Restricted Subsidiaries, taken as a whole; 

(10) restrictions imposed under any agreement to sell Equity Interests or assets, as permitted under this Indenture, to any Person pending the
closing of such sale; 
 (11) any other agreement governing Indebtedness or other obligations that either (A) contains encumbrances and
restrictions that in the good faith judgment of the Company are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Escrow Release Date with respect to that Restricted Subsidiary pursuant to
agreements in effect on the Escrow Release Date or (B) any such encumbrance or restriction is customary and does not prohibit (except upon a default or an event of default thereunder) the payment of dividends in an amount sufficient, as
determined by the Company in good faith, to make scheduled payments of cash interest and principal on the Notes when due; 
 (12) customary
provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements, shareholder agreements and other similar agreements that in each case restrict the disposition or distribution of
ownership interests in or assets of the partnership, limited liability company, joint venture, corporation or similar Person governed thereby;

Indebtedness shall be permitted (the “Permitted Indebtedness”): 
 (1) the incurrence of Indebtedness by the
Company and (subject to the Non-Guarantor Debt Cap) the Restricted Subsidiaries under one or more Credit Facilities in an aggregate principal amount at any time outstanding, not to exceed $5.95 billion;

Subsidiary permitted to be incurred in accordance with the provisions of this Indenture; provided that in the event such Indebtedness that is being guaranteed is Subordinated Indebtedness, the related guarantee shall be subordinated in right
of payment to the Notes or the Guarantee, as the case may be; 
 (5) Indebtedness under Hedging Obligations entered into for
bona fide hedging purposes of the Company or any Restricted Subsidiary or Permitted Joint Venture in the ordinary course of business and not for the purpose of speculation; provided that (i) in the case of Hedging Obligations relating to

 63 

 
Hedging Obligations relate to payment obligations on Indebtedness not prohibited to be incurred by this Section 4.9, and (b) the notional principal amount of such Hedging Obligations at
the time incurred does not exceed the principal amount of the Indebtedness to which such Hedging Obligations relate, and (ii) with respect to Hedging Obligations entered into on behalf of or with respect to an obligation of a Permitted Joint
Venture, such Permitted Joint Venture or a holder of Equity Interests thereof (other than Company or any of its Restricted Subsidiaries), in each case which the Company reasonably determines to be creditworthy, agrees in writing to indemnify or
reimburse the Company or a Restricted Subsidiary for any payments made on or with respect to such Hedging Obligation; 
 (6)
Indebtedness of the Company owed to and held by a Restricted Subsidiary and Indebtedness of any Restricted Subsidiary owed to and held by the Company or any other Restricted Subsidiary; provided, however, that

obligee, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes; 

(b) if an Issuer or a Guarantor is the obligor on such Indebtedness and a Restricted Subsidiary that is not an Issuer or a
Guarantor is the obligee, such Indebtedness is subordinated in right of payment to the obligations hereunder of such Issuer or the Guarantee of such Guarantor, as applicable; and 

(c) 

(i) any subsequent issuance or transfer of Equity Interests or any other event which results in any such Indebtedness being
held by a Person other than the Company or any Restricted Subsidiary; and 
 (ii) any sale or other transfer of any such
Indebtedness to a Person other than the Company or any other Restricted Subsidiary, 
 shall be deemed, in each case of this clause (c),

any Person acquiring all or any portion of such business, assets or Equity Interests for the purpose of financing or in contemplation of any such acquisition; provided that (a) any amount of such obligations included on the face of the
balance sheet of the Company or any Restricted Subsidiary shall not be permitted under this clause (12) (contingent obligations referred to on the face of a balance sheet or in a footnote thereto and not otherwise quantified and reflected on
the balance sheet will not be deemed “included on the face of the balance sheet” for purposes of the foregoing) and (b) in the case of a disposition, the maximum aggregate liability in respect of all such obligations outstanding under
this clause (12) shall at no time exceed the gross proceeds actually received by the Company and the Restricted Subsidiaries in connection with such disposition;

for shares of common stock of the Company, together with the legacy notes into which such exchangeable note will split in one or more transactions. 

  
 66 

 Notwithstanding anything to the contrary, a Restricted Subsidiary that is not an Issuer or a
Guarantor may not (and the Company will not permit any Restricted Subsidiary that is not an Issuer or a Guarantor to) incur any Indebtedness pursuant to the Coverage Ratio Exception or clause (1), (13) or (19) of this Section 4.9(b) if,
after giving effect to such incurrence on a pro forma basis (including giving pro forma effect to the application of the proceeds thereof), the aggregate principal amount of Indebtedness outstanding pursuant to the Coverage Ratio Exception and
clauses (1), (13) and (19) of this Section 4.9(b) that was incurred by Restricted Subsidiaries that are not an Issuer or a Guarantor would exceed the sum of (i) the greater of (x) $400.0 million and (y) 5.0% of the Company’s
Consolidated Total Assets determined at the time of incurrence and (ii) in the case of one or more Restricted Subsidiaries that are not Guarantors that are in the Company’s Middle East segment and are engaged in the business of acquiring,
owning, developing, constructing or operating a fabrication yard and marine base and related facilities, assets and offices in the Kingdom of Saudi Arabia, $200.0 million; provided that Indebtedness of a Restricted Subsidiary that is not a
Guarantor that was incurred under clause (1) of the definition of “Permitted Indebtedness” shall be excluded from such limitation so long as the Company is not in violation of the covenant set forth under Section 4.17 (this
paragraph is referred to as the “Non-Guarantor Debt Cap”). 
 For purposes of
determining compliance with this Section 4.9, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (22) above or is entitled to be
incurred pursuant to the Coverage Ratio Exception, the Company shall, in its sole discretion, classify such item of Indebtedness and may divide and classify such Indebtedness in more than one of the types of Indebtedness described (except that all
Indebtedness outstanding under the Credit Agreement on the Escrow Release Date (after giving effect to the Transactions) will, at all times, be treated as incurred on the Escrow Release Date under clause (1) above and may not be reclassified),
and may later reclassify any item of Indebtedness described in clauses (1) through (22) above (provided that at the time of reclassification it meets the criteria in such category or categories). In addition, for purposes of
determining any particular amount of Indebtedness under this Section 4.9, (i) guarantees or letter of credit obligations supporting Indebtedness otherwise included in the determination of such particular amount shall not be included so
long as incurred by a Person that could have incurred such Indebtedness; and (ii) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof
determined in accordance with GAAP. 
 For the purposes of determining compliance with any U.S. dollar denominated restriction on the
incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier
of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in
a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such
refinancing, such U.S. dollar-denominated restriction shall 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. The
principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which
such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 

  
 67 

 Notwithstanding any other provision of this Section 4.9, in no event shall the
reclassification of any lease or other liability as indebtedness due to a change in accounting principles after December 31, 2017 (whether or not such lease or liability existed on December 31, 2017) be deemed to be an incurrence of
Indebtedness. 
 If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary then
outstanding shall be deemed to be incurred by a Restricted Subsidiary as of such time (and, if such Indebtedness is not permitted to be incurred as of such time under this Section 4.9, the Company shall be in Default of this Section 4.9).

 SECTION 4.10. Limitations on Asset Sales. 

(a) From and after the Escrow Release Date, the Company will not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
consummate any Asset Sale unless: 
 (1) the Company or such Restricted Subsidiary, as the case may be, receives
consideration at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale or, in circumstances where the Company or such Restricted Subsidiary grants a third party the
right to purchase an asset, the date of such grant) of the shares and assets subject to such Asset Sale; and 
 (2) at
least 75.0% of the total consideration from such Asset Sale and all other Asset Sales on a cumulative basis since the Escrow Release Date received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash
Equivalents. 
 For purposes of clause (2) above and for no other purpose, the following shall be deemed to be cash: 

(A) the amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness or intercompany Indebtedness) or
other obligations of the Company or such Restricted Subsidiary that is expressly assumed by the transferee of any such assets pursuant to a written agreement that releases the Company or such Restricted Subsidiary from further liability therefor,

 (B) the amount of any securities, notes or other obligations received from such transferee that are
within 180 days after such Asset Sale converted by the Company or such Restricted Subsidiary into cash (to the extent of the cash actually so received), 

  
 68 

 (C) any Designated Non-cash Consideration
received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this
Section 4.10(a)(2)(C) that is at that time outstanding, not to exceed the greater of (i) $150.0 million and (ii) 2.5% of the Company’s Consolidated Total Assets at the time of receipt of such Designated Non-cash Consideration, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to
subsequent changes in value, and 
 (D) the Fair Market Value of (i) any assets (other than securities) received by the
Company or any Restricted Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary
concurrently with the acquisition of such Person by the Company or (iii) a combination of (i) and (ii). 
 If at any time any non-cash consideration received by the Company or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than
interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net
Available Proceeds therefrom shall be applied in accordance with this Section 4.10. 
 Any Asset Sale pursuant to an Event of Loss
shall not be required to satisfy the conditions set forth in clauses (1) and (2) of this Section 4.10(a). 
 (b) If the
Company or any Restricted Subsidiary engages in an Asset Sale the Net Available Proceeds of which do not exceed $500.0 million, the Company or such Restricted Subsidiary may, no later than 365 days following the consummation thereof,
apply all or any of the Net Available Proceeds therefrom to: 
 (1) prepay, repay, redeem, cash collateralize or otherwise
retire Indebtedness and other obligations that are secured by one or more Liens; 
 (2) prepay, repay, redeem or purchase
senior Indebtedness of the Company or any Guarantor; provided, that, the Company shall (y) apply a pro rata portion (determined and as modified based on the provisions set forth below) of such Net Available Proceeds to redeem or repurchase
Notes (i) as described above under Section 3.07 or (ii) through open market purchases at a purchase price not less than 100% of the principal amount thereof, plus accrued but unpaid interest thereon, or (z) make an offer (in
accordance with the procedures set forth below) to all Holders to purchase their Notes at a purchase price not less than 100% of the principal amount thereof, plus accrued but unpaid interest thereon (in each case other than Indebtedness or other
obligations owed to the Company or an Affiliate of the Company); or 
 (3) (i) make any capital expenditure or otherwise
invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities and excluding working capital or current assets for the avoidance of doubt) to be used by the Company or any Restricted Subsidiary in a
Permitted Business, (ii) acquire Qualified 

  
 69 

 
Equity Interests held by a Person other than the Company or any of its Restricted Subsidiaries in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that
shall become a Restricted Subsidiary concurrently with the consummation of such acquisition or (iii) a combination of (i) and (ii); provided that any such capital expenditure or investment made pursuant to a definitive binding
agreement or a commitment approved by the Board of Directors of the Company that is executed or approved within such time will satisfy this requirement, so long as such capital expenditure or investment is consummated within 180 days of such 365th
day. 
 If the Company or any Restricted Subsidiary engages in an Asset Sale the Net Available Proceeds of which exceed $500.0 million,
the Company shall only apply such Net Available Proceeds in accordance with clauses (1) and (2) of the immediately preceding paragraph. The amount of Net Available Proceeds not applied or invested as provided in clauses (1), (2) or (3) of
the immediately preceding paragraph will constitute “Excess Proceeds.” 
 (c) On the 366th day (or such longer period
as provided above) after an Asset Sale (or, at the Company’s option, an earlier date), if the aggregate amount of Excess Proceeds equals or exceeds $25.0 million, the Issuers shall be required to make an offer (with a copy to the Trustee)
to purchase or redeem (a “Net Proceeds Offer”) from all Holders and, to the extent required by the terms of other Pari Passu Indebtedness of the Company or any of its Restricted Subsidiaries, to all holders of other Pari Passu Indebtedness
outstanding with similar provisions requiring the Company or any Restricted Subsidiary to make an offer to purchase or redeem such Pari Passu Indebtedness with the proceeds from any Asset Sale, to purchase or redeem the maximum principal amount of
Notes and any such Pari Passu Indebtedness to which the Net Proceeds Offer applies that may be purchased or redeemed out of the Excess Proceeds, at an offer price in cash in an amount equal to 100.0% of the principal amount of Notes and Pari
Passu Indebtedness plus accrued and unpaid interest thereon to (but excluding) the date of purchase, in accordance with the procedures set forth in this Indenture and the agreements governing the Pari Passu Indebtedness, as applicable, in each case
in minimum denominations of $2,000 or integral multiples of $1,000 in excess thereof. 
 To the extent that the sum of the aggregate
principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer is less than the Excess Proceeds, the Company and its Restricted Subsidiaries may use any remaining Excess Proceeds, or a portion thereof, for
any purposes not otherwise prohibited by the provisions of this Indenture. If the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer exceeds the amount of Excess Proceeds, the Company
or the Issuers shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate outstanding principal amount of Notes and Pari Passu Indebtedness. Upon completion of such Net Proceeds Offer in
accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero. 

(d) The Net Proceeds Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a
longer period is required by applicable law (the “Net Proceeds Offer Period”). No later than five Business Days after the termination of the Net Proceeds Offer Period (the “Net Proceeds Purchase Date”), the
Company or one or more 

  
 70 

 
of its Subsidiaries will purchase the principal amount of Notes and Pari Passu Indebtedness required to be purchased pursuant to this Section 4.10 (the “Net Proceeds Offer
Amount”) or, if less than the Net Proceeds Offer Amount has been so validly tendered, all Notes and Pari Passu Indebtedness validly tendered in response to the Net Proceeds Offer. 

If the Net Proceeds Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and
unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Net Proceeds Offer. 

Pending the final application of any Net Available Proceeds pursuant to this Section 4.10, the Company or the Restricted Subsidiary, as
applicable, may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving Credit Facility or otherwise invest such Net Available Proceeds in any manner not prohibited by this Indenture. 

On or before the Net Proceeds Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent
necessary, the Net Proceeds Offer Amount of Notes and Pari Passu Indebtedness or portions of Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer
Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn, in each case in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.
The Issuers or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Net Proceeds Offer Period) mail or deliver to each tendering Holder and the Company or the Issuers will
mail or deliver to each tendering holder or lender of Pari Passu Indebtedness, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Indebtedness so validly tendered and not properly withdrawn by such holder or lender,
as the case may be, and accepted by the Company or the Issuers for purchase, and, unless the Notes are held solely in global form, the Issuers will issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Issuers,
will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a minimum principal amount of $2,000 or an
integral multiple of $1,000 in excess thereof. In addition, the Company or the applicable Restricted Subsidiaries will take any and all other actions required by the agreements governing the Pari Passu Indebtedness. Any Note not so accepted will be
promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers will publicly announce the results of the Net Proceeds Offer on the Net Proceeds Purchase Date. 

Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Company and its
Restricted Subsidiaries, taken as a whole, will be governed by Section 4.14 and/or Section 5.1 and not by this Section 4.10. 

The Issuers shall comply with all applicable securities laws and regulations in the United States, including, without limitation, the
requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions
of any applicable securities laws or regulations conflict with this Section 4.10, the Issuers 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. 

  
 71 

 Notwithstanding any of the other provisions of this Section 4.10, the Company or any of its
Restricted Subsidiaries (other than the Issuers) may take any of the actions required by such other provisions of this Section 4.10 to be taken by the Issuers and any such actions so taken by the Company or any of such Restricted Subsidiaries
will be deemed to have been taken by the Issuers. 
 SECTION 4.11. Limitation on Transactions with Affiliates. 

(a) From and after the Escrow Release Date, the Company will not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee
with, or for the benefit of, any Affiliate (an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $5.0 million, unless: 

(1) the terms of such Affiliate Transaction are not materially less favorable to the Company or such Restricted Subsidiary, as
the case may be, than those that could reasonably be expected to have been obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an
Affiliate or are otherwise fair to the Company or such Restricted Subsidiary from a financial point of view; and 
 (2) the
Company delivers to the Trustee, with respect to any Affiliate Transaction involving aggregate value in excess of $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and,
with respect to any Affiliate Transaction involving aggregate value in excess of $40.0 million, a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by a majority of the Independent Directors
approving such Affiliate Transaction. 
 (b) The foregoing restrictions shall not apply to: 

(1) transactions to the extent between or among (a) the Company and one or more Restricted Subsidiaries or
(b) Restricted Subsidiaries; 
 (2) director, officer, employee and consultant compensation (including bonuses) and
other benefits (including pursuant to any employment agreement or arrangement, severance agreement, consulting agreement or any retirement, health, stock option, other equity award or other benefit plan), payments or loans (or cancellation of loans)
to employees of the Company or any Restricted Subsidiary and indemnification arrangements, including reimbursement or advance of out-of-pocket expenses and provision of
officers’ and directors’ liability insurance; 
 (3) any Permitted Investments (other than pursuant to
clause (1) of the definition thereof); 

  
 72 

 (4) any Restricted Payments which are made in accordance with Section 4.7;

 (5) any agreement, arrangement or commitment in effect on the Issue Date or as thereafter amended or replaced in any
manner that, taken as a whole, is not more disadvantageous to the Company in any material respect than such agreement as it was in effect on the Issue Date; 

(6) any transaction with a Person (other than an Unrestricted Subsidiary of the Company) which would constitute an Affiliate of
the Company solely because the Company or a Restricted Subsidiary owns an Equity Interest in or otherwise controls such Person; 

(7) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the
ordinary course of business and otherwise in compliance with the applicable terms of this Indenture; provided that in the reasonable determination of the Board of Directors of the Company or the senior management of the Company, such
transactions are on terms not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an
arm’s-length basis from a Person that is not an Affiliate of the Company; 
 (8)
(a) any transaction with an Affiliate where the only consideration paid by the Company or any Restricted Subsidiary is Qualified Equity Interests and (b) the issuance or sale of any Qualified Equity Interests and the granting of registration
and other customary rights in connection therewith; 
 (9) pledges by the Company or any Restricted Subsidiary of Equity
Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Unrestricted Subsidiaries; 

(10) any agreement, arrangement, commitment or transaction entered into by a Person prior to the time such Person becomes a
Subsidiary or is merged or consolidated into the Company or a Restricted Subsidiary (provided that such transaction is not entered into in contemplation of such event) or as thereafter amended or replaced in any manner that, taken as a whole, is not
more disadvantageous to the Company in any material respect than such agreement, arrangement, commitment or transaction as it was in effect on the date such Person became a Subsidiary or was merged or consolidated into the Company or a Restricted
Subsidiary; 
 (11) dividends and distributions to the Company or a Restricted Subsidiary by any Unrestricted Subsidiary or
Permitted Joint Venture; and 
 (12) transactions entered into as part of a Receivables Program. 

SECTION 4.12. Limitations on Liens. From and after the Escrow Release Date, the Company will not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (other than Permitted Liens) upon any of their property or assets (including Equity Interests of any Restricted Subsidiary), whether owned
at the Issue Date or thereafter acquired, which Lien secures Indebtedness, unless contemporaneously with the incurrence of such Lien: 

  
 73 

 (1) in the case of any Lien securing Indebtedness that ranks pari passu with the
Notes or a Guarantee, effective provision is made to secure the Notes or such Guarantee, as the case may be, at least equally and ratably with or prior to such Indebtedness with a Lien on the same collateral; and 

(2) in the case of any Lien securing Indebtedness that is subordinated in right of payment to the Notes or a Guarantee,
effective provision is made to secure the Notes or such Guarantee, as the case may be, with a Lien on the same collateral that is senior to the Lien securing such subordinated Indebtedness, in each case, for so long as such obligation is secured by
such Lien. 
 SECTION 4.13. Payments for Consent. The Issuers will not, and will not permit any of its Subsidiaries to, directly
or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such
consideration is offered to be paid and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 

SECTION 4.14. Offer to Purchase upon Change of Control. Upon the occurrence of any Change of Control, unless the Issuers have
previously or concurrently exercised its right to redeem all of the Notes as described under Section 3.7, each Holder will have the right to require that the Issuers purchase all or any portion (equal to $2,000 or an integral multiple of $1,000
in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon to (but
excluding) the date of purchase. 
 Not later than 30 days following any Change of Control, the Issuers will deliver, or cause to
be delivered, to the Holders, with a copy to the Trustee, a notice: 
 (1) describing the transaction or transactions that
constitute the Change of Control; 
 (2) offering to purchase, pursuant to the procedures required by this Indenture and
described in the notice (a “Change of Control Offer”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the
“Change of Control Payment Date”), and for the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer prior to 5:00 p.m. New York time on the second Business Day
preceding the Change of Control Payment Date; and 
 (3) describing the procedures, as determined by the Issuers, consistent
with this Indenture, that Holders must follow to accept the Change of Control Offer. 

  
 74 

 On or before the Change of Control Payment Date, the Issuers will, to the extent lawful, deposit
with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of the Notes or portions of Notes properly tendered. 

On the Change of Control Payment Date, the Issuers will, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes (of $2,000 or integral multiples of $1,000 in excess thereof) properly tendered pursuant
to the Change of Control Offer; and 
 (2) deliver or cause to be delivered to the Trustee the Notes so accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuers. 
 The
Paying Agent will promptly deliver to each Holder who has so tendered Notes the Change of Control Purchase Price for such Notes, 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 so tendered, if any; provided that each such new Note will be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof. 

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, the accrued
and unpaid interest will be paid on the relevant interest payment date to the Person in whose name a Note is registered at the close of business on such record date. 

A Change of Control Offer shall remain open for at least 20 Business Days or for such longer period as is required by applicable law. The
Issuers shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

The Issuers’ obligation to make a Change of Control Offer shall be satisfied (i) if 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 Issuers and purchases all Notes properly tendered and not withdrawn under such Change of
Control Offer or (ii) in connection with or in contemplation of any publicly announced Change of Control, the Issuers have made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price
equal to or higher than the Change of Control Purchase Price and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer. 

If Holders of not less than 90% in aggregate principal amount of the outstanding Notes, validly tender and do not withdraw such Notes in
a Change of Control Offer or Alternate Offer and the Issuers, or any third party making a Change of Control Offer or Alternate Offer in lieu of the Issuers as described above, purchases all of such Notes validly tendered and not withdrawn by such
Holders, the Issuers will have the right, upon not less than 30 days’ nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or
Alternate Offer, as applicable, to redeem all of the Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Purchase Price or Alternate Offer price, as applicable, plus, to the
extent not included in the Change of Control Purchase Price, accrued and unpaid interest to (but excluding) the date of redemption. 

  
 75 

 For the avoidance of doubt, in no event will the consummation of the Transactions constitute a
“Change of Control” or be deemed to be a disposition of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole. 

The Issuers shall comply with all applicable securities legislation in the United States, including, without limitation, the requirements of Rule 14e-l under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any
applicable securities laws or regulations conflict with this Section 4.14, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.14 by
virtue of such compliance. 
 The provisions under this Indenture relating to the Issuers’ obligation to make a Change of Control Offer
may be waived, modified or terminated with the written consent of the Holders of a majority in principal amount of the Notes then outstanding. 

Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control,
conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer. 

SECTION 4.15. Corporate Existence. Subject to Section 4.14 and Article V, as the case may be, and other than in
connection with the Escrow Mergers, the Company and each Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and, from and after the Escrow Release Date, the corporate,
partnership, limited liability company or other existence of each of its Restricted Subsidiaries in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company, each Issuer or any such
Restricted Subsidiary and the rights (charter and statutory), licenses and franchises of the Company, each Issuer and its Restricted Subsidiaries; provided that the Company and Issuers shall not be required to preserve any such right, license
or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors of the Company or each Issuer, as applicable, shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company or each Issuer, as applicable, and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders. 

SECTION 4.16. Business Activities. The Company shall engage, and shall cause its Restricted Subsidiaries to engage, in businesses
that, when considered together as a single enterprise, are primarily the Permitted Business. 
 SECTION 4.17. Additional
Guarantees. From and after the Escrow Release Date, if any Restricted Subsidiary of the Company, other than an Issuer or a Guarantor, shall guarantee any Indebtedness of an Issuer or any Guarantor under a Credit Facility consisting of debt for

  
 76 

 
borrowed money (including, for the avoidance of doubt, the Credit Agreement), then the Company shall, within 30 days thereof, cause such Restricted Subsidiary to execute and deliver to the
Trustee a supplemental indenture in substantially the form attached hereto as Exhibit C, pursuant to which such Restricted Subsidiary shall become a Guarantor with respect to the Notes, upon the terms and subject to the
release provisions and other limitations described under Section 10.1; provided that, if such guarantee with respect to the Notes (i) is by a Person organized outside of the United States and would result in any breach of any law or
regulation (or analogous restriction) of the jurisdiction of organization of such Person or result in a substantial risk to the officers or directors of such Person of a civil or criminal liability, or (ii) requires any governmental approval or
third party consents, in each case such Restricted Subsidiary shall use commercially reasonable efforts to obtain all governmental approval(s) and third party consent(s), as applicable, so that such Person would not be in breach of any such law or
regulation (or analogous restriction) and would not result in such substantial risk, and to otherwise permit such Restricted Subsidiary to become a Guarantor, and such Restricted Subsidiary shall not be required to become a Guarantor until 30 days
after all such governmental approvals and third party consents have been obtained and remain in full force and effect. 
 SECTION 4.18.
Limitations on Designation of Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Subsidiary (including any newly formed or newly acquired Subsidiary or a Person becoming a Subsidiary through merger or
consolidation or Investment therein, but excluding the Issuers) of the Company as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if: 

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; 

(2) the Company would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an
Investment pursuant to Section 4.7, in either case, in an amount (the “Designation Amount”) equal to the Fair Market Value of the Company’s proportionate interest in such Subsidiary on such date; and 

(3) following any designation as an Unrestricted Subsidiary, such Unrestricted Subsidiary shall not be permitted to own, or
hold an exclusive license to, any Material Intellectual Property. 
 No Subsidiary shall be Designated as an “Unrestricted
Subsidiary” unless: 
 (1) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the date of Designation, consist
of Non-Recourse Debt, except for any guarantee given solely to support the pledge by the Company or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not
recourse to the Company or any Restricted Subsidiary; 
 (2) on the date such Subsidiary is Designated an Unrestricted Subsidiary, and for
so long as such Subsidiary is an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding (other than a guarantee permitted under clause (1) above) with the Company or any Restricted
Subsidiary unless the terms of the agreement, contract, arrangement or understanding, taken as a whole, are not materially less favorable to the Company or the Restricted Subsidiary than those that could reasonably be expected to have been obtained
at the time from Persons who are not Affiliates of the Company, as determined in good faith by the Company; and 

  
 77 

 (3) such Subsidiary is a Person with respect to which neither the Company nor any of its
Restricted Subsidiaries has any direct or indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any
specified levels of operating results (in each case other than a guarantee permitted under clause (1) above). 
 Any such Designation
by the Board of Directors of the Company shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Company giving effect to such Designation and an Officers’ Certificate certifying that such
Designation complies with the foregoing conditions. If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this
Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.9 or the
Lien is not permitted under Section 4.12, the Company shall be in default of the applicable covenant. Notwithstanding anything to the contrary, no Guarantor may be designated as an Unrestricted Subsidiary if it provides (or continues to
provide) a guarantee of the obligations under any Credit Facility unless such Guarantor is substantially concurrently being designated as an “unrestricted subsidiary” under such Credit Facility or its guarantee of the obligations under
such Credit Facility are being released substantially concurrently therewith. 
 The Board of Directors of the Company may redesignate an
Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if: 
 (1) no Default shall have occurred and be
continuing at the time of and after giving effect to such Redesignation; and 
 (2) all Liens, Indebtedness and Investments of such
Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture. 

Any such Redesignation shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Company
giving effect to such designation and an Officers’ Certificate certifying that such Redesignation complies with the foregoing conditions. 

SECTION 4.19. Covenant Suspension. 

(a) If on any date following the Escrow Release Date (i) the Notes have an Investment Grade Rating from both Rating Agencies and
(ii) no Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the
Company and the Restricted Subsidiaries will not be subject to the following covenants (collectively, the “Suspended Covenants”): 

(1) Section 4.7; 

  
 78 

 (2) Section 4.8; 

(3) Section 4.9; 

(4) Section 4.10; 

(5) Section 4.11; 

(6) Section 4.16; and 

(7) Section 5.1(a)(3). 

(b) In the event that the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any
period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an
Investment Grade Rating, then the Company and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. 

(c) The Company shall promptly notify the Trustee of the occurrence of any Covenant Suspension Event or Reversion Date by filing with the
Trustee an Officers’ Certificate certifying the same; provided, however, that the Trustee shall have no obligation to monitor the ratings of the Notes or to discover or verify the existence or termination of any Covenant
Suspension Event, Suspension Period or Reversion Date and may conclusively rely on such Officers’ Certificate, but may provide a copy of such Officers’ Certificate to any Holder upon request. 

(d) The period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to herein as the
“Suspension Period.” Solely for the purpose of determining the amount of Permitted Liens in accordance with the provisions of Section 4.12 during any Suspension Period and without limiting the Company’s or any Restricted
Subsidiary’s ability to incur Indebtedness without restriction during any Suspension Period, to the extent that calculations as set forth in the definition of “Permitted Liens” refer to the covenant set forth in Section 4.9, such
calculations shall be made as though the covenant set forth in Section 4.9 remains in effect during the Suspension Period. Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Excess Proceeds shall be reset at zero.

 (e) In the event of any reinstatement of the Suspended Covenants, from and after the Reversion Date, no action taken or omitted to be
taken by the Company or any of its Restricted Subsidiaries prior to such reinstatement will give rise to a Default under this Indenture with respect to the Notes; provided, however, that with respect to Restricted Payments made after
any such reinstatement, the amount of Restricted Payments made will be calculated as though the covenant as set forth in Section 4.7 had been in effect prior to, but not during, the Suspension Period. No Subsidiaries shall be designated as
Unrestricted Subsidiaries during the Suspension Period. All Indebtedness incurred during the Suspension Period will be classified to have been 

  
 79 

 
incurred or issued pursuant to clause (3) of the definition of “Permitted Indebtedness” herein. Any Affiliate Transaction entered into after the Reversion Date pursuant to an
agreement entered into during any Suspension Period shall be deemed to be permitted pursuant to clause (5) of Section 4.11(b). 

SECTION 4.20. Activities Prior to the Escrow Release. 

(a) Prior to the Escrow Release Date, the primary activities of each Initial Co-Issuer
shall be restricted to issuing the Notes, issuing capital stock and receiving capital contributions, performing its obligations in respect of the Notes under this Indenture and the Escrow Agreement, performing its obligations under the Combination
Agreement, if any, consummating the Transactions and the Release, redeeming the Notes pursuant to Section 3.9, if applicable, and conducting such other activities as are necessary or appropriate to carry out the activities in this
Section 4.20 and in the Combination Agreement. 
 (b) Prior to the Escrow Release Date, the Initial Co-Issuers shall not own, hold or otherwise have any interest in any assets other than the Escrow Account, the funds and Eligible Escrow Investments on deposit therein, cash and Cash Equivalents, and its rights
under the Indenture Documents and the Combination Agreement, if any. 
 (c) For the avoidance of doubt, this
Section 4.20 shall no longer apply once the Escrow Mergers are consummated.

provided, that if the Surviving Entity is not a corporation and the remaining Issuer is not a corporation, a Restricted Subsidiary that is a corporation expressly assumes as co-obligor all of the
obligations of such Issuer under this Indenture and the Notes pursuant to a supplemental indenture to this Indenture executed and delivered to the Trustee; 

(2) immediately after giving effect to such transaction and the assumption of the obligations as set forth in

that such merger, consolidation or transfer and such agreement and/or supplemental indenture (if any) comply with the Indenture Documents. 

For purposes of this Section 5.1, any Indebtedness of the Surviving Entity which was not Indebtedness of the applicable Issuer
immediately prior to the transaction shall be deemed to have been incurred in connection with such transaction. 
 (b) Except in
circumstances which provide for the release of the Guarantee of a Guarantor in accordance with the provisions of Section 10.5, no Guarantor shall, and the Company shall not permit any Guarantor to, directly or indirectly, in a single

 (c) Upon any consolidation or
merger of an Issuer or a Guarantor, or any transfer of all or substantially all of the assets of the Company in accordance with the foregoing, in which an Issuer or such Guarantor is not the continuing obligor under the Notes or its Guarantee, as
applicable, the surviving entity formed by such consolidation or merger or into which such Issuer or such Guarantor is merged or the Person to which the sale, conveyance, lease, transfer, disposition or assignment is made shall succeed to, and be
substituted for, and may exercise every right and power of, such Issuer or such Guarantor under this Indenture, the Notes and the Guarantees with the same effect as if such surviving entity had been named therein as such Issuer or such Guarantor
and, so long as the applicable Issuer’s or the applicable Guarantor’s obligations under the Indenture Documents are assumed as provided above, except in the case of a lease, such Issuer or such Guarantor, as the case may be, shall be

(a) is caused by a failure to pay at its Stated Maturity principal on such Indebtedness within the applicable express grace
period and any extensions thereof, or 
 (b) results in the acceleration of such Indebtedness prior to its Stated Maturity,

than by reason of release of such Guarantor from its Guarantee in accordance with the terms of this Indenture and the Guarantee). 

SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.1(8) with respect to
the Company or an Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Company, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice
to the Company and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the aggregate principal of and accrued and unpaid interest on
the outstanding Notes shall become due and payable immediately. 

  
 84 

 If an Event of Default specified in clause (8) of Section 6.1 occurs with respect to
the Company or any Issuer, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on
the part of the Trustee or any Holder of the Notes or any other action or notice, to the extent permitted by applicable law. 
 After any
acceleration described above in this Section 6.2, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the Notes then outstanding may rescind and annul such acceleration if: 

(1) the rescission would not conflict with any judgment or decree; 

(2) all existing Events of Default have been cured or waived other than nonpayment of accelerated principal and interest; 

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become
due otherwise than by such declaration of acceleration, has been paid; 
 (4) the Issuers have paid the Trustee its reasonable compensation
and reimbursed the Trustee for its reasonable expenses, disbursements and advances; and 
 (5) in the event of the cure or waiver of an
Event of Default (other than an Event of Default described in clauses (1), (2) or (8) of Section 6.1), the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been
cured or waived. 
 No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

SECTION 6.3. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal, premium, if any, and interest 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 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. 
 SECTION 6.4. Waiver of Past Defaults. Subject to Section 9.2, the Holders of a majority in
aggregate principal amount of the Notes then outstanding by written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default and its consequences under this Indenture except a
continuing Default in the payment of interest or premium on, or the principal of, the Notes, which shall require the consent of all of the Holders of the Notes then outstanding. 

  
 85 

 SECTION 6.5. Control by Majority. The Holders of a majority in aggregate principal
amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee. However, (i) the Trustee may refuse to follow any direction that conflicts with law or
this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction (it being understood that the Trustee
does not have an affirmative duty to ascertain whether or not any such direction prejudices the rights of such Holders) and (ii) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with any such
direction received from the Holders. 
 SECTION 6.6. Limitation on Suits. A Holder may pursue a remedy with respect to this
Indenture or the Notes only if: 
 (a) the Holder gives to the Trustee written notice of a continuing Event of Default; 

(b) the Holder or Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the
Trustee to pursue the remedy; 
 (c) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs,
liability or expense; 
 (d) the Trustee does not comply with the request within sixty (60) days after receipt of the request and the
offer of indemnity; and 
 (e) during such 60-day period, the Holders of a majority in
aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request. 
 A Holder
may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a
Holder prejudices the rights of any other Holders or obtains priority or preference over such other Holders). 
 SECTION 6.7. Rights
of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, or interest on, such Note or to bring suit for the enforcement of any such
payment, on or after the due date expressed in the Notes, shall not be impaired or affected without the consent of the Holder. 

SECTION 6.8. Collection Suit by Trustee. If an Event of Default specified in Section 6.1(1) or Section 6.1(2) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium and interest remaining unpaid on the Notes and interest on overdue
principal and, to the extent lawful, 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.

  
 86 

 SECTION 6.9. Trustee May 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 (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders allowed in any judicial proceedings relative to the Issuers (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
securities or property payable or deliverable upon the conversion or exchange of the Notes or 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 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 under Section 7.6. To the extent that the payment of any such compensation, expenses, disbursements and advances to the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.6 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 or property pursuant to this Article VI, it shall pay out
the money and property in the following order: 
 First: to the Trustee, its agents and attorneys for amounts due
under Section 7.6 and 11.5, as applicable, including payment of all reasonable compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

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

Third: without duplication, to the Holders for any other Obligations owing to the Holders under this Indenture and the
Notes; and 
 Fourth: to the Company or to such party as a court of competent jurisdiction shall direct. 

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

  
 87 

 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 and expenses, 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 6.7, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. 

ARTICLE VII 
 TRUSTEE 

SECTION 7.1. 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 his or her own affairs. 

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

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need
perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii) the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed
therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; however, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished
to the Trustee, the Trustee shall examine such certificates and opinions furnished to it to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or
other facts stated therein). 
 (c) The Trustee may not be relieved from liabilities for its own grossly negligent action, its own grossly
negligent failure to act, or its own willful misconduct, except that: 
 (i) this paragraph does not limit the effect of
paragraph (b) of this Section 7.1; 
 (ii) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer of the Trustee, unless it is proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 

  
 88 

 (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 6.5; and 
 (iv) no

not be liable for interest on or the investment of any money received by it except as the Trustee may agree in writing with the Issuers. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by
law. 
 (e) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is
subject to clauses (a) through (d) of this Section 7.1. 
 SECTION 7.2. Rights of Trustee. 

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting on any resolution, certificate,
statement, instrument, opinion, notice, report, request, direction, consent, order, bond, debenture or other document (whether in original or facsimile form) 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 therein. 
 (b) Before the Trustee acts or refrains from acting, it may require an
Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. Prior to taking, suffering or
admitting any action, the Trustee may consult with counsel of the Trustee’s own choosing, and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in
conclusive reliance on the advice or opinion of such counsel. 
 (c) The Trustee may act through its attorneys, attorneys-in-fact and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed 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. 
 (e) Unless otherwise specifically provided in this Indenture, any demand, request,
direction or notice from the Issuers or a Guarantor shall be sufficient if signed by an Officer of the Issuers or such Guarantor. 
 (f) The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee security or indemnity satisfactory to
the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 

  
 89 

 (g) The Trustee shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours the books, records and
premises of the Issuers, personally or by agent or attorney at the sole cost of the Issuers, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee, the Agents and each other agent, attorney, attorney-in-fact, custodian and Person employed to act
hereunder. 
 (i) The Trustee may request that the Issuers and each of the Guarantors shall deliver to the Trustee an Officers’
Certificate setting forth the names of individuals and/or titles of Officers of the Issuers and each Guarantor, as applicable, authorized at such time to take specified actions pursuant to this Indenture, the Notes and the Guarantees, which
Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

(j) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or the Trustee shall have received from the Issuers or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 11.1 and such notice references the Notes and this
Indenture. In the absence of such actual knowledge or such notice, the Trustee may conclusively assume that no such Default exists. 
 (k)
In no event shall the Trustee be responsible or liable for special, indirect, punitive, 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. 
 (l) The Trustee shall not be required to give any bond or
surety in respect of the performance of its powers and duties hereunder. 
 (m) The permissive rights of the Trustee to do things enumerated
in this Indenture shall not be construed as a duty unless so specified herein. 
 (n) No provision of this Indenture shall be deemed to
impose any duty or obligation on the Trustee to take or omit to take any action, in the performance of its duties or obligations under this Indenture, or to exercise any right or power thereunder, to the extent that taking or omitting to take such
action would violate applicable law binding upon it. 

  
 90 

 SECTION 7.3. Individual Rights of the Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of any Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee
acquires any conflicting interest, it must eliminate such conflict within ninety (90) days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the Trust Indenture Act of 1939, as amended) or
resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.9 hereof. 
 SECTION 7.4.
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 Guarantee, it shall not be accountable for the use of the
proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ 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, any Officers’ Certificate delivered to the Trustee hereunder, or any other document in connection with the sale of the Notes or pursuant
to this Indenture other than the Trustee’s certificate of authentication hereunder. 
 SECTION 7.5. Notice of Defaults. If
a Default occurs and is continuing and if it is known to the Trustee as provided in Section 7.02(j), the Trustee shall deliver to Holders a notice of the Default within 60 days after it occurs. Except in the case of a Default in
payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good
faith determines that withholding the notice is in the interests of the Holders. 
 SECTION 7.6. Compensation and Indemnity The
Issuers shall pay to the Trustee from time to time compensation for its acceptance of this Indenture and for all services rendered by it hereunder as agreed upon in writing. The Trustee’s compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Issuers 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, except any
such disbursements, expenses and advances as may be attributable to the Trustee’s gross negligence, bad faith or willful misconduct as determined by a final, non-appealable judgment of a court of
competent jurisdiction. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

Each of the Issuers and the Guarantors, jointly and severally, shall indemnify, defend, protect, and hold the Trustee (which for purposes of
this Section 7.6 shall include its officers, directors, employees and agents) harmless against any and all claims, damages, losses, liabilities, costs or expenses incurred by it (including, without limitation, the reasonable and documented out-of-pocket fees and expenses of its agents and counsel) arising out of or in connection with the acceptance or administration of its duties under this Indenture, the
performance of its obligations and/or exercise of its rights hereunder, including the costs and expenses of enforcing this Indenture against the Issuers or any Guarantor (including this Section 7.6) and defending itself against any claim
(whether asserted by the Issuers 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, claim, damage, liability or expense shall
be caused by its own 

  
 91 

 
gross negligence, bad faith or willful misconduct as determined by a final, non-appealable judgment of a court of competent jurisdiction. The Trustee shall
notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers of its obligations hereunder. The Trustee may have one separate counsel in each relevant
jurisdiction, and the Issuers shall pay the reasonable and documented out-of-pocket fees and expenses of such counsel for the Trustee. The Issuers need not pay for any
settlement made without its consent, which consent shall not be unreasonably withheld. 
 The obligations of the Issuers and the Guarantors
under this Section 7.6 shall survive the discharge of this Indenture, the payment of the Notes or the resignation or removal of the Trustee. 

To secure the Issuers’ payment obligations in this Section 7.6, 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 or interest, if any, on particular Notes. Such Lien shall survive the discharge of this Indenture, the payment of the Notes and the resignation or removal of the
Trustee. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(8) 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. 

SECTION 7.7. 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 7.7. 
 The Trustee may resign
in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee upon 30 days’ prior notice to the Trustee and
the Issuers in writing. The Issuers may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.9 hereof; 

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to such Trustee under any Bankruptcy
Law; 
 (c) a 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 the Trustee for any reason, the Issuers shall promptly appoint a
successor trustee. Within one year after the successor trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor trustee to replace the successor trustee appointed by the Issuers. 

  
 92 

 If a successor trustee does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee (at the Issuers’ expense), the Issuers or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a
successor trustee. 
 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply
with Section 7.9 hereof, 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 Issuers. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the successor trustee shall have all the rights, powers and the 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 that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.6.
Notwithstanding replacement of the Trustee pursuant to this Section 7.7, the Issuers’ and the Guarantors’ obligations under Section 7.6 shall continue for the benefit of the retiring Trustee. 

SECTION 7.8. Successor Trustee by Merger, Etc. If the Trustee or any Agent consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business (including this transaction) to, another corporation, the successor corporation without any further act shall be the successor Trustee or Agent, as applicable. 

SECTION 7.9. 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 or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. Such Trustee
together with its affiliates shall at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition. 

ARTICLE VIII 
 DEFEASANCE;
DISCHARGE OF THIS INDENTURE 
 SECTION 8.1. Option to Effect Legal Defeasance or Covenant Defeasance. The Issuers may, at the
option of their respective Boards of Directors and evidenced by a board resolution and an Officers’ Certificate, at any time, elect to have either Section 8.2 or Section 8.3 applied to all outstanding Notes upon compliance with the
conditions set forth below in this Article VIII. 
 SECTION 8.2. Legal Defeasance. Upon the Issuers’ exercise under
Section 8.1 of the option applicable to this Section 8.2, the Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from their obligations with
respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors shall be deemed to have paid
and discharged the entire Obligations represented by the Notes and the Guarantees, which shall thereafter be deemed to be 

  
 93 

 
outstanding only for the purposes of Section 8.5 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other Obligations under
such Notes, Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuers, shall execute instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated
or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and interest and premium, if any, on such Notes when such payments are due from the trust referred to in
Section 8.4(1); (b) the Issuers’ obligations with respect to such Notes under Section 2.2, Section 2.3, Section 2.4, Section 2.5, Section 2.6, Section 2.7, Section 2.10, Section 2.15,
Section 2.17, Section 4.1 and Section 4.2; (c) the rights, powers, trusts, benefits, duties and immunities of the Trustee, including without limitation thereunder, under Section 7.6, Section 8.5 and Section 8.7 and
the obligations of the Issuers and the Guarantors in connection therewith; and (d) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Issuers may exercise their option under this Section 8.2
notwithstanding the prior exercise of its option under Section 8.3. 
 SECTION 8.3. Covenant Defeasance. Upon the
Issuers’ exercise under Section 8.1 above of the option applicable to this Section 8.3, the Issuers shall, subject to the satisfaction of the conditions set forth in Section 8.4 below, be released from their obligations under
Section 4.3, Section 4.7, Section 4.8, Section 4.9, Section 4.10, Section 4.11, Section 4.12, Section 4.14, Section 4.16, Section 4.17, Section 4.18, and Section 5.1 (a)(3) with
respect to the outstanding Notes, in each case, on and after the date the conditions set forth below 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, the Issuers or any of their Subsidiaries 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 6.1, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Issuers’ exercise under Section 8.1 of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4, Section 6.1(3), Section 6.1(4),
Section 6.1(5), Section 6.1 (6), and Section 6.1(9) shall not constitute Events of Default. 
 Notwithstanding any discharge
or release of any obligations pursuant to Section 8.2 or Section 8.3, the Issuers’ and the Guarantors’ obligations, as applicable, in Section 2.5, Section 2.6, Section 2.7, Section 2.10, Section 2.15,
Section 2.17, Section 4.1, Section 4.2, Section 7.6, Section 8.5 and Section 8.7 shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.8. After the Notes are no longer
outstanding, the Issuers’ obligations in Section 7.6, Section 8.5 and Section 8.7 shall survive. 

  
 94 

 SECTION 8.4. Conditions to Legal or Covenant Defeasance. The following shall be the
conditions to the application of either Section 8.2 or Section 8.3 to the outstanding Notes: 
 (1) the Issuers
must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without
consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuers which is delivered to the Trustee, to pay the principal of and
interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, 

(2) in the case of Legal Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that: 
 (A) the Issuers have received from, or there has been published by
the United States Internal Revenue Service, a ruling, or 
 (B) 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 shall confirm
that, the Holders and beneficial owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the 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, 

(3) in the case of Covenant Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that the Holders and beneficial owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the 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 the Covenant Defeasance had not occurred, 

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the
borrowing of funds to be applied to make the deposit required to effect such Legal Defeasance or Covenant Defeasance and the granting of any Lien securing such borrowings), 

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any
other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound (other than this Indenture), 

(6) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by them
with the intent of preferring the Holders over any other of their creditors or with the intent of defeating, hindering, delaying or defrauding any other of their creditors or others, and 

(7) the Issuers shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each to the effect
that the applicable conditions precedent provided for in clauses (1) through (6) have been complied with. 

  
 95 

 SECTION 8.5. Deposited Money and U.S. Government Obligations to Be
Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.6, all U.S. legal tender and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively,
for purposes of this Section 8.5, the “Deposit Trustee”) pursuant to Section 8.4 or Section 8.8 in respect of the outstanding Notes shall be held in trust, shall not be invested, and shall be applied by the Deposit
Trustee in accordance with the provisions of such Notes and this Indenture to the payment, either directly or through any Paying Agent (including the Issuers or any Subsidiary acting as Paying Agent) as the Deposit Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Issuers shall pay and indemnify the Deposit Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 8.4 or Section 8.8 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 VIII to the contrary notwithstanding,
the Deposit Trustee shall deliver or pay to the Issuers from time to time upon the written request of the Issuers and be relieved of all liability with respect to any U.S. legal tender or non-callable
U.S. Government Obligations held by it as provided in Section 8.4 or Section 8.8 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Deposit Trustee (which may be the opinion delivered under Section 8.4(1) or Section 8.8(1)(b)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance
or discharge, as applicable. 
 If the funds deposited with the Deposit Trustee to effect Covenant Defeasance or Legal Defeasance or
discharge, as applicable are insufficient to pay the principal of and interest on the Notes when due, then the Issuer’s obligations and the obligations of the Guarantors under this Indenture will be revived and no such defeasance or discharge
will be deemed to have occurred. 
 SECTION 8.6. Repayment to Issuers. Any money deposited with the Trustee or any Paying
Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal and premium, if any, or interest has become due and payable shall,
unless otherwise required by mandatory provisions of applicable escheat, or abandoned or unclaimed property law, be paid to the Issuers on their written request or (if then held by the Issuers) shall be discharged from such trust; and the Holder of
such Note shall thereafter, as an unsecured general creditor, look only to the Issuers for payment thereof; and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof,
shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any 

  
 96 

 
such repayment, may at the expense of the Issuers cause to be published once, in the New York Times and 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 shall be repaid to the Issuers. 

SECTION 8.7. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. dollars or U.S. Government
Obligations in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application,
then the obligations of the Issuers and the Guarantors under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, Section 8.3 or Section 8.8 until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be; provided, however, that, if the Issuers make any payment of principal of,
premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

SECTION 8.8. Discharge. This Indenture shall be discharged and shall cease to be of further effect (except as to rights of
registration of transfer or exchange of Notes which shall survive until all Notes have been canceled and the rights, protections and immunities of the Trustee) as to all outstanding Notes when: 

(1) either: 
 (a)
all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuers and
thereafter repaid to the Issuers or discharged from this trust), have been delivered to the Trustee for cancellation; or 

(b) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable (by reason of the
making of a notice of redemption or otherwise), (ii) will become due and payable within one year, (iii) have been called for redemption pursuant to Section 3.7 or (iv) are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and, in any case in clauses (i)-(iv), the Issuers have irrevocably deposited or caused to be deposited
with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any
reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuers delivered to the Trustee (in the case of U.S. Government Obligations) to pay and
discharge the entire Indebtedness (including all principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation; 

  
 97 

 (2) the Issuers have paid or caused to be paid all other sums payable by it under this Indenture;

 In addition, the Issuers must deliver an
Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to the discharge of this Indenture pursuant to this Section 8.8 have been complied with. 

In the case of clause (b) of this Section 8.8, and subject to the next sentence and notwithstanding the foregoing paragraph, the
Issuers’ and the Guarantors’ obligations, as applicable, in Section 2.2, Section 2.3, Section 2.4, Section 2.5, Section 2.6, Section 2.7, Section 2.10, Section 2.12, Section 2.15,
Section 2.17, Section 4.1, Section 4.2, Section 4.15 (as to legal existence of the Issuers only), Section 7.6, Section 8.5 and Section 8.7 shall survive until the Notes are no longer outstanding pursuant to the
last paragraph of Section 2.8. After the Notes are no longer outstanding, the Issuers’ and the Guarantors’ obligations in Section 7.6, Section 8.5 and Section 8.7 shall survive any discharge pursuant to this
Section 8.8. 
 After such delivery or irrevocable deposit and receipt of the Officers’ Certificate and Opinion of Counsel, the
Trustee, upon written request, shall acknowledge in writing the discharge of the Issuers’ obligations under the Notes and this Indenture except for those surviving obligations specified above. 

ARTICLE IX 
 AMENDMENT, SUPPLEMENT
AND WAIVER 
 SECTION 9.1. Without Consent of Holders . Notwithstanding Section 9.2, without the consent of any of
the Holders, the Issuers, the Guarantors and the Trustee, at any time and from time to time, may amend or supplement this Indenture, the Guarantees, the Notes issued hereunder for any of the following purposes: 

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

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes (provided, that the uncertificated
Notes are issued in registered form for purposes of Section 163(f) of the Internal Revenue Code of 1986, as amended); 

(3) to provide for the assumption of an Issuer’s or a Guarantor’s obligations to the Holders in the case of a merger,
consolidation or sale of all or substantially all of such Issuer’s or such Guarantor’s assets or sale, lease, transfer, conveyance or other disposition or assignment in accordance with Section 5.1; 

(4) to add any Guarantee or to effect the release of any Guarantor from any of its obligations under its Guarantee or the
provisions of this Indenture (to the extent in accordance with this Indenture); 

  
 98 

 (5) to make any change that would provide any additional rights or benefits to
the Holders or that does not materially adversely affect the rights of any Holder; 
 (6) to secure the Notes or any
Guarantees or any other obligation under this Indenture; 
 (7) to evidence and provide for the acceptance of appointment by
a successor trustee; 
 (8) to conform the text of this Indenture, the Guarantees or the Notes to any provision of the
“Description of the Notes” contained in the Offering Memorandum, to the extent that such provision in such “Description of the Notes” purports to describe a provision of this Indenture, the Guarantees, or the Notes, as described
in an Officers’ Certificate to the Trustee; or 
 (9) to provide for the issuance of Additional Notes in accordance with
this Indenture. 
 After an amendment under this Indenture becomes effective, the Issuers shall deliver to Holders a notice briefly
describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment. 

SECTION 9.2. With Consent of Holders. With the consent of the Holders of not less than a majority in aggregate principal amount of
the outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture, the
Notes or the Guarantees, or, subject to Section 6.4 and Section 6.7, waive any existing Default or compliance with any provision of this Indenture or the Notes; provided, however, that without the consent of each affected
Holder, no amendment, supplement or waiver under this Section 9.2 may (with respect to any Notes held by a non-consenting Holder): 

(1) reduce, or change the maturity of, the principal of any Note; 

(2) reduce the rate of or extend the time for payment of interest on any Note; 

(3) reduce any premium payable upon redemption of the Notes or change the date on which any Notes are subject to redemption
(other than the notice provisions) or waive any payment with respect to the redemption of the Notes; provided, however, that solely for the avoidance of doubt, and without any other implication, any purchase or repurchase of Notes (including
pursuant to Section 4.10 and Section 4.14) shall not be deemed a redemption of the Notes; 
 (4) make any Note
payable in money or currency other than that stated in the Notes; 
 (5) modify or change any provision of this Indenture or
the related definitions to affect the ranking of the Notes or any Guarantee in a manner that adversely affects the Holders; 

  
 99 

 (6) reduce the percentage of Holders necessary to consent to an amendment or
waiver to this Indenture or the Notes; 
 (7) waive a default in the payment of principal of or premium, if any, or interest
on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in this Indenture and a waiver of the payment default that resulted from such acceleration); 

(8) release any Guarantor from any of its obligations under its Guarantee or this Indenture, except as permitted by this
Indenture; or 
 (9) make any change in these amendment and waiver provisions. 

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 SECTION 9.3. 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 and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the
consenting Holder’s Note, even if notation of the consent is not made on the Note. However, any such Holder or subsequent Holder 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. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder. 

The Issuers may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or
waiver. If the Issuers fix a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such
solicitation pursuant to Section 2.5 or (ii) such other date as the Issuers shall designate. 
 SECTION 9.4. 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 Issuers 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 9.5. Trustee to Sign Amendments, Etc. The Trustee shall sign any
amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In signing or refusing to sign any amendment or
supplemental indenture, the Trustee shall be provided with and (subject to Section 7.1) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or
supplemental indenture is authorized or permitted by this Indenture, that all conditions precedent thereto have been met or waived, that such amendment or supplemental indenture is not inconsistent herewith and that it will be valid and binding upon
the Issuers and the Guarantors in accordance with its terms.

 ARTICLE X 

GUARANTEES 
 SECTION 10.1.
Guarantees. 
 (a) Subject to this Article X, from and after the Escrow Release Date upon delivery of the applicable supplemental
indenture as set forth in Section 10.2, each Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and obligations of the Issuers hereunder and thereunder, and guarantees to each Holder of a Note authenticated
and delivered by the Trustee and to the Trustee, that: (i) the principal of and premium, if any, and interest on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise (including,
without limitation, the amount that would become due but for the operation of the automatic stay under Section 362(a) of Title 11 of the U.S. Code), together with interest on the overdue principal, if any, and interest on any overdue
interest, to the extent lawful, and all other Obligations of the Issuers to the Holders or the Trustee under this Indenture or the Notes shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case
of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration
or otherwise. Each of the Guarantees shall be a guarantee of payment and not of collection. 
 (b) Each Guarantor hereby agrees that its
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 Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. 

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers or any other Person, any right to request the division of the payment obligations among the Guarantors, protest, notice and all demands whatsoever
and covenants that the Guarantee of such Guarantor shall not be discharged as to any Note or this Indenture except by complete performance of the obligations contained in such Note and this Indenture and such Guarantee. Each of the Guarantors hereby
agrees that, in the event of a Default in payment of principal or premium, if any, or interest on any Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the
Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce each such Guarantor’s Guarantee without first proceeding against the
Issuers or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to
accelerate the maturity of the Notes, to collect interest on the Notes, or to 

  
 101 

 
enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would
otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders and any other amounts due and owing to the Trustee under this Indenture. 

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuers or any Guarantor, or any custodian, trustee,
liquidator or other similar official acting in relation to the Issuers or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated
in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive
the termination of this Indenture. 
 (e) Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee of such Guarantor, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor. 
 (f) Each Guarantor acknowledges
that each Guarantee will be a general obligation of such Guarantor and will rank senior in right of payment to all future Obligations of such Guarantor that are, by their terms, expressly subordinated in right of payment to such Guarantee and equal
in right of payment with all existing and future obligations of such Guarantor that are not so subordinated. 
 (g) Each Guarantor that
makes a payment for distribution under its Guarantee is entitled upon payment in full of all guaranteed obligations under this Indenture to seek contribution from the Issuers for the full amount of such payment and from each other Guarantor in a pro
rata amount of such payment based on the respective net assets of all the Guarantors at the time of such payment in accordance with GAAP or applicable law. 

SECTION 10.2. Execution and Delivery of Guarantee. To evidence its Guarantee set forth in Section 10.1, an authorized
officer, director or other authorized person, as the case may be, of each Guarantor shall, (i) with regard to each Guarantor becoming a party hereto on the Escrow Release Date, execute a supplemental indenture substantially in the form of
Exhibit B hereto and (ii) with regard to each Guarantor that becomes a party hereto after the Escrow Release Date, execute a supplemental indenture substantially in the form of Exhibit C hereto. 

Each Guarantor hereby agrees that its Guarantee set forth in Section 10.1 hereof shall remain in full force and effect notwithstanding
the absence of the endorsement of any notation of such Guarantee on the Notes. In case the Officer, board member or director of such Guarantor whose signature is on this Indenture or supplemental indenture, as applicable, no longer holds office at
the time the Trustee authenticates any Note, the Guarantee shall be valid nevertheless. 

  
 102 

 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors. 
 If required by Section 4.17
hereof, the Company shall cause each Restricted Subsidiary described in Section 4.17 hereof to comply with the provisions of Section 4.17 hereof and this Article X, to the extent applicable. 

SECTION 10.3. Severability. In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 10.4.
Limitation of Guarantors’ Liability. (a) Each Guarantor and by its acceptance hereof each Holder 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 the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or
conveyance. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Guarantee (other than a company that is a direct or indirect parent of the
Issuers) shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from, rights to receive contribution from or payments made
by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee, result in the obligations of such Guarantor under its Guarantee constituting a fraudulent conveyance, fraudulent preference, or
fraudulent transfer or otherwise reviewable transaction under applicable law. 
 (b) Regarding the Guarantee, each Guarantor hereby
irrevocably waives any right to require a proceeding first against any Issuer or any other Person, any right to request the division of their payment obligation among the Guarantors and any right to request that collateral be foreclosed upon,
however such rights may be denominated under the laws of any jurisdiction. 
 (c) Notwithstanding anything in this Indenture to the
contrary, if any Subsidiary of the Parent is or becomes a Guarantor, and such Subsidiary is or becomes an Excluded Subsidiary, such Subsidiary will not be considered a party to this Agreement or a Guarantor hereunder in any respects, and will not
have any obligations under this Agreement, until such time that it is no longer an Excluded Subsidiary. “Excluded Subsidiary” shall mean any non-U.S. Subsidiary if at such time such
Subsidiary’s Guarantee is prohibited by (x) any governmental authority with authority over such non-U.S. Subsidiary or (y) applicable law or regulation or analogous restriction, or such
Subsidiary’s Guarantee would result in a substantial risk to the officers or directors of such Subsidiary or a civil or criminal liability. 

(d) Any supplemental indenture pursuant to which any Guarantor becomes a party to this Indenture may contain further limitations on such
Guarantor’s Guarantee to the extent either (i) similar limitations exist for such Guarantor’s guarantee in respect of any Credit Facility or (ii) required by or reasonably necessary pursuant to the law of the jurisdiction of
organization or formation of such Guarantor. 

  
 103 

 SECTION 10.5. Releases. A Guarantor shall be released and relieved of any Obligations
under its Guarantee and this Indenture: 
 (a) upon any sale, exchange or transfer (by merger, consolidation or otherwise) of
the Equity Interests of such Guarantor (other than the Company) after which the applicable Guarantor is no longer a Restricted Subsidiary, which sale, exchange or transfer does not violate this Indenture; 

(b) upon designation by the Board of Directors of the Company as an Unrestricted Subsidiary in accordance with the terms of
this Indenture; 
 (c) upon such Guarantor ceasing to guarantee the Indebtedness of either Issuer or any Guarantor under any
Credit Facility consisting of debt for borrowed money (including, for the avoidance of doubt, the Credit Agreement), except if such release or discharge is by or as a result of payment under such guarantee; provided that no continuing Event
of Default relating to the failure to make required payments on the Notes exists; 
 (d) if the Issuers exercise the Legal
Defeasance option or the Covenant Defeasance option pursuant to Section 8.2 or Section 8.3 or if this Indenture is discharged in accordance with Section 8.8; 

(e) in accordance with the provisions of Article IX; or 

(f) upon dissolution of such Guarantor. 

Upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that all conditions precedent to the
release of a Guarantor’s Guarantee set forth in this Indenture have been satisfied, the Trustee shall execute any documents reasonably requested by the Issuers in writing 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 on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article X. 

SECTION 10.6. Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and indirect benefits from the
financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

action or proceeding may be heard and determined in such New York State or federal court and hereby irrevocably waive, to the fullest extent that they may legally do so, the defense of an inconvenient forum to the maintenance of such action or
proceeding, and, in the case of the Guarantors organized under the laws of Mexico, the right to any other jurisdiction. 

  
 107 

 Nothing in this Indenture or any other Indenture Document or otherwise shall affect any right

SECTION 11.9. No Adverse Interpretation of Other Agreements. This Indenture may not be used to interpret any other indenture, loan
or debt agreement of the Issuers or its Subsidiaries or of any other Person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. 

SECTION 11.10. Successors. All agreements of the Issuers and the Guarantors in this Indenture and the Notes and the Guarantees, as
applicable, shall bind their respective successors and assigns. All agreements of any Trustee in this Indenture shall bind its respective successors and assigns. 

SECTION 11.11. Severability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by 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 Issuers. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the “Act” of 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 conclusive in
favor of the Trustee and the Issuers, if made in the manner provided in this Section 11.14. 

  
 108 

 (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 such
officer the execution thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. 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 maintained by the Registrar hereunder. 

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future
Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuers in reliance
thereon, whether or not notation of such action is made upon such Note. 
 (e) If the Issuers shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the Issuers may, at their option, by or pursuant to a board resolution of each of the Issuer’s Board of Directors, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuers shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite
proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date;
provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record
date. 
 SECTION 11.15. Waiver of Jury Trial. EACH OF THE ISSUERS, THE GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES, THE GUARANTEES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

SECTION 11.16. Force Majeure. In no event shall the Trustee or any Agent be responsible or liable for any failure or delay in the
performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, fire, riots, strikes, or stoppages for any reason, embargoes, governmental actions, accidents,
acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, it being understood that the
Trustee shall use reasonable efforts which are consistent with accepted practices in the U.S. banking industry to resume performance as soon as practicable under the circumstances.

 SECTION 11.17. Documents in English. The parties to this Indenture have expressly
requested that this Indenture and all related notices, amendments and other documents be drafted in the English language. 

SECTION 11.18. Conversion of Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due
under this Indenture to the Holder from U.S. dollars to another currency, the Issuers and each Guarantor have agreed, and each Holder by holding such Note will be deemed to have agreed, to the fullest extent that the Issuers, each Guarantor and
they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day
preceding the day on which final judgment is given. 
 The Issuers’ and Guarantors’ obligations to any Holder will,
notwithstanding any judgment in a currency (the “Judgment Currency”) other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any
amount in such Judgment Currency, such Holder may in accordance with normal banking procedures purchase U.S. dollars with the judgment currency. If the amount of the U.S. dollars so purchased is less than the amount originally to be paid
to such Holder or the Trustee in the Judgment Currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Issuers and the Guarantors, jointly and severally, agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify the Holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such Holder or the Trustee,
as the case may be, such Holder or the Trustee, as the case may be, will pay the Issuers and the Guarantors, such excess as certified in an Officers’ Certificate delivered to the Trustee; provided that such Holder or the Trustee, as the
case may be, shall not have any obligation to pay any such excess as long as a Default under the Notes or this Indenture has occurred and is continuing or if the Issuers or the Guarantors shall have failed to pay any Holder or the Trustee any
amounts then due and payable under such Note or this Indenture, in which case such excess may be applied by such Holder or the Trustee to such Obligations. 

SECTION 11.19. Service of Process. Each of the Issuers and each non-U.S. Guarantor
hereby appoints McDermott Technology (Americas), Inc. as its agent for service of process in any suit, action or proceeding with respect to this Indenture, the Notes or the Guarantees and for actions brought under federal or state securities laws
brought in any federal or state court located in The City of New York. 
 SECTION 11.20. Legal Holidays. If any payment date
falls on a day that is not a Business Day, the payment to be made on such payment date will be made on the next succeeding Business Day with the same force and effect as if made on such payment date, and no additional interest will accrue solely as
a result of such delayed payment.

 (Back of 10.625% Senior Note) 

10.625% Senior Notes due 2024 

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

(1) Interest. The Issuers promise to pay interest on the principal amount of this 10.625% Senior Note due 2024 (a
“Note”) at a fixed rate of 10.625% per annum. The Issuers will pay interest in U.S. dollars (except as otherwise provided herein) semiannually in arrears on May 1 and November 1, commencing on November 1,
2018 (each, an “Interest Payment Date”) or if any such day is not a Business Day, on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, and no additional interest shall accrue
solely as a result of such delayed payment. Interest on the Notes shall accrue from the most recent date to which interest has been paid, or, if no interest has been paid, from and including the date of issuance. The Issuers shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; they shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at the same rate to the extent lawful. Interest shall be computed on the basis of
a 360-day year comprised of twelve 30-day months. 

(2) Method of Payment. The Issuers will pay interest on the Notes (except defaulted interest) on the applicable Interest Payment Date
to the Persons who are registered Holders at the close of business on the April 15 and October 15 preceding the Interest Payment Date (whether or not a Business Day), 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. If a Holder of at least $5 million principal amount of Notes has given written wire transfer instructions to an account in
the continental United States to the Trustee at least ten Business Days prior to the applicable Interest Payment Date, the Issuers will make all payments of principal, premium and interest on such Holder’s Notes by wire transfer of immediately
available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Trustee or Paying Agent within the City and State of New York unless the Issuers elect to make interest
payments by check mailed to the Holders at their addresses set forth in the register of Holders. 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. 
 Any payments of principal of this Note prior to Stated Maturity shall be binding upon all future Holders of this Note and
of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The final principal amount due and payable at the maturity of this Note shall be payable only upon presentation and
surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes. Notwithstanding anything to the contrary in this Note or in the Indenture, payments in respect of Global Notes will be made by wire transfer
of immediately available funds to the Depositary. 

  
 A-5 

 (3) Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association shall
act as Paying Agent and Registrar. The Issuers may change any Paying Agent or Registrar without notice to any Holder, and the Issuers and/or any Restricted Subsidiaries may act as Paying Agent or Registrar. 

(4) Indenture. The Initial Co-Issuers issued the Notes under an Indenture, dated as of
April 18, 2018 (the “Indenture”), among the Initial Co-Issuers and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and
Holders are referred to the Indenture for a statement of such terms. The Initial Notes are senior obligations of the Issuers limited to $1,300,000,000 in aggregate principal amount. The Indenture permits the issuance of Additional Notes subject to
compliance with certain conditions. 
 The payment of principal and interest on the Notes and all other amounts under the Indenture, upon
the Escrow Release Date, shall be unconditionally guaranteed, jointly and severally, on a senior basis by the Guarantors. 
 (5) Optional
Redemption. 
 (a) The Notes may be redeemed, in whole or in part, at any time prior to May 1, 2021 at the option of the Issuers
upon notice in accordance with the provisions of Section 3.3 of the Indenture, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium (calculated by the Issuers as certified in an
Officers’ Certificate to the Trustee, showing the calculation of such in reasonable detail) as of, and accrued and unpaid interest, if any, to (but excluding), the applicable redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment date). 
 (b) The Notes are subject to redemption, at the
option of the Issuers, in whole or in part, at any time or from time to time on or after May 1, 2021, upon notice in accordance with the provisions of Section 3.3 of the Indenture, at the following redemption prices (expressed as
percentages of the principal amount to be redeemed) set forth below, plus accrued and unpaid interest, if any, on the Notes to be redeemed to (but excluding) the applicable redemption date (subject to the right of Holders on the relevant record date
to receive interest due on the relevant interest payment date), if redeemed during the 12-month period beginning May 1 of the years indicated below: 

 

					
	 Year
	  	Redemption Price	 
	 2021
	  	 	105.313	% 
	 2022
	  	 	102.656	% 
	 2023 and thereafter
	  	 	100.000	% 

 (c) The Issuers may acquire Notes by means other than a redemption, whether pursuant to a tender offer, open
market purchase, negotiated transaction or otherwise, in accordance with applicable securities laws. 

  
 A-6 

 (d) At any time or from time to time prior to May 1, 2021, the Issuers, at their option, may
on any one or more occasions, upon notice in accordance with the provisions of Section 3.3 of the Indenture, redeem up to 35.0% of the aggregate principal amount of the outstanding Notes issued under the Indenture (calculated after giving
effect to any issuance of Additional Notes), in an amount not greater than the net cash proceeds of one or more Qualified Equity Offerings of the Company (which have not been applied to permanently repay other Indebtedness) at a redemption price
equal to 110.625% of the principal amount of such Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to (but excluding) the applicable date of redemption (subject to the right of Holders of record on the relevant record
date to receive interest due on the relevant interest payment date); provided that: 
 (1) at least 65.0% of the
aggregate principal amount of Notes being redeemed issued under the Indenture on the Issue Date remains outstanding immediately after giving effect to any such redemption; and 

(2) each such redemption occurs not more than 180 days after the date of the closing of any such Qualified Equity
Offering. 
 (e) If an Issuer or a Guarantor becomes obligated to pay any Additional Amounts as a result of a change in the laws or
regulations of any Specified Tax Jurisdiction, or a change in any official written position of any Specified Tax Jurisdiction regarding the application or interpretation thereof (including a holding by a court of competent jurisdiction), which is
first publicly announced and becomes effective on or after the Issue Date (or, if later, on or after the date the relevant Specified Tax Jurisdiction first becomes a Specified Tax Jurisdiction) and such Additional Amounts cannot (as certified in an
Officers’ Certificate to the Trustee) be avoided by the use of reasonable measures available to the Issuers (including changing the jurisdiction of a paying agent or making the relevant payment by or through a different Issuer or Guarantor),
then the Issuers may, at their option, redeem the Notes, in whole but not in part, upon notice in accordance with the provisions of Section 3.3 of the Indenture (such notice to be provided not less than 30 nor more than 90 days before
the next date on which the Issuers would be obligated to pay Additional Amounts), at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but excluding) the redemption date and all
Additional Amounts, if any, then due or that will otherwise become due on the redemption date as a result of the redemption (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date
that is on or prior to the redemption date and Additional Amounts (if any) in respect thereof). Notice of the Issuers’ intent to redeem the Notes shall not be effective until such time as it delivers to the Trustee an Opinion of Counsel stating
that the Issuers are obligated to pay Additional Amounts because of an amendment to or change in law or regulation or official position as described in this paragraph. 

(6) Mandatory Redemption. Except for a Special Mandatory Redemption pursuant to Section 3.9 in the Indenture, the Issuers shall
not be required to make mandatory redemption or sinking fund payments with respect to Notes. 
 (7) Repurchase at Option of Holder.

 (a) If a Change of Control occurs, unless the Issuers at such time have given notice of redemption pursuant to Paragraph (5) hereof
with respect to all outstanding Notes, each Holder will have the right to require the Issuers to repurchase all or any part (equal to $2,000 or an 

  
 A-7 

 
integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to a Change of Control Offer at a price in cash equal to 101.0% of the principal amount of Notes
repurchased plus accrued and unpaid interest to (but excluding) the date of purchase; provided that no partial redemption shall result in a Note having a principal amount of less than $2,000. Not later than 30 days following any
Change of Control unless the Issuers at such time has given notice of redemption pursuant to Paragraph (5) hereof with respect to all outstanding Notes, the Issuers will deliver a notice to each Holder (with a copy to the Trustee) describing
the transaction or transactions that constitute the Change of Control and setting forth the procedures governing the Change of Control Offer required by the Indenture. 

(b) Following the occurrence of certain Asset Sales, the Issuers may be required to offer to purchase Notes. 

(c) Holders of the Notes that are the subject of an offer to purchase will receive notice of a Net Proceeds Offer or the Change of Control
Offer, as applicable, pursuant to an Asset Sale or a Change of Control from the Issuers prior to any related purchase date and may elect to have such Notes purchased by completing the form titled “Option of Holder to Elect Purchase”
attached hereto. 
 (8) Notice of Redemption. Notice of redemption shall be delivered at least fifteen (15) days but not more
than sixty (60) days before the redemption date to each Holder whose Notes are to be redeemed in accordance with the applicable provisions of Article III and Section 11.1 of the Indenture. Notes in denominations larger than $2,000 may be
redeemed in part but only in minimum denominations of $2,000 and integral multiples of $1,000 thereof, unless all of the Notes held by a Holder are to be redeemed so long as no partial redemption results in a Note having a principal amount of less
than $2,000. 
 (9) Special Mandatory Redemption. In the event that (a) the Initial
Co-Issuers shall have notified the Trustee and Escrow Agent in writing that the Combination will not be consummated on or prior to the date that is two Business Days prior to the Outside Date, (b) the
Initial Co-Issuers shall have notified the Trustee and the Escrow Agent in writing that the Escrow Conditions are determined by the Initial Co-Issuers to be incapable of
being satisfied on or prior to the Outside Date, or (c) the Initial Co-Issuers shall have notified the Trustee and the Escrow Agent in writing that the Combination will not be consummated or that the
Combination Agreement has been terminated (any such event, a “Special Mandatory Redemption Event”), the Escrow Agent shall, without the requirement of notice to or action by the Initial
Co-Issuers, the Trustee or any other Person, release and deliver the Escrowed Funds to the Trustee not later than the third Business Day succeeding the date of any such notice (any such notice being referred
to herein as “Special Redemption Notice”), and the Trustee will apply such Escrowed Funds to redeem all of the Notes (the “Special Mandatory Redemption”) at a price equal to 100.0% of the initial issue price of such
Note plus accrued and unpaid interest thereon to (but not including) the date fixed for such redemption (the “Special Mandatory Redemption Date”) as specified in the Special Redemption Notice, which date may be no later than one
Business Day after the Outside Date. Concurrently with the delivery of the Special Redemption Notice, the Initial Co-Issuers will instruct the Trustee to, at the Initial
Co-Issuers’ expense, send (by first-class mail to each Holder’s registered address or otherwise in accordance with the procedures of DTC) a notice that a Special Mandatory Redemption will occur on
the Special Mandatory Redemption Date. Upon the consummation of the Combination, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply. 

  
 A-8

severally, fully and conditionally, Guaranteed by the Guarantors to the extent set forth in the Indenture. 
 (11) 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 the Notes may be registered and the Notes may be exchanged as provided in
the Indenture. The Registrar, any Trustee and the Issuers may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuers may require a Holder to pay any stamp or transfer tax or similar
government charge required by law or permitted by the Indenture in accordance with Section 2.6(g)(2) of the Indenture. The Registrar is not required (A) to issue, to register the transfer of or to exchange Notes during a period beginning

redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date. 

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

(13) Amendment, Supplement and Waiver. Subject to the following paragraphs, the Indenture, the Notes and the Guarantees may be amended
or supplemented with the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes, including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer
for, Notes, and, except as set forth in the Indenture, any existing Default or compliance with any provision of the Indenture, the Notes or the Guarantees may be waived with the consent of the Holders of a majority in principal amount of the then
outstanding Notes, including consents obtained in connection with a tender offer or exchange offer for Notes. 
 Notwithstanding
Section 9.2 of the Indenture, without the consent of any of the Holders, the Issuers, the Guarantors and the Trustee at any time and from time to time, may amend or supplement the Indenture, the Guarantees or the Notes for any of the following
purposes: 
 (1) to cure any ambiguity, defect or inconsistency; 

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes (provided, that the uncertificated
Notes are issued in registered form for purposes of Section 163(f) of the Internal Revenue Code of 1986, as amended); 

(3) to provide for the assumption of an Issuer’s or a Guarantor’s obligations to the Holders in the case of a merger,

 (4) to add any Guarantee or to effect the release of any Guarantor from any of

(5) to make any change that would provide any additional rights or benefits to the Holders or that does not materially
adversely affect the rights of any Holder; 
 (6) to secure the Notes or any Guarantees or any other obligation under the
Indenture; 
 (7) to evidence and provide for the acceptance of appointment by a successor trustee; 

(8) to conform the text of the Indenture, the Guarantees or the Notes to any provision of the “Description of the
Notes” contained in the Offering Memorandum, to the extent that such provision in such “Description of the Notes” purports to describe a provision of the Indenture, the Guarantees or the Notes, as described in an Officers’
Certificate to the Trustee; or 
 (9) to provide for the issuance of Additional Notes in accordance with the Indenture. 

With the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), the Issuers, the Guarantors and the Trustee may amend or supplement the Indenture, the Notes or the Guarantees, or, subject to
Section 6.4 and Section 6.7 of the Indenture, waive any existing Default or compliance with any provision of the Indenture or the Notes; provided, however, that without the consent of each affected Holder, no amendment,
supplement or waiver under this paragraph may (with respect to any Notes held by a non-consenting Holder): 

(1) reduce, or change the maturity of, the principal of any Note; 

(2) reduce the rate of or extend the time for payment of interest on any Note; 

(3) reduce any premium payable upon redemption of the Notes or change the date on which any Notes are subject to redemption
(other than the notice provisions) or waive any payment with respect to the redemption of the Notes; provided, however, that solely for the avoidance of doubt, and without any other implication, any purchase or repurchase of Notes
(including pursuant to Section 4.10 and Section 4.14 of the Indenture) shall not be deemed a redemption of the Notes; 

(4) make any Note payable in money or currency other than that stated in the Notes; 

(5) modify or change any provision of the Indenture or the related definitions to affect the ranking of the Notes or any
Guarantee in a manner that adversely affects the Holders; 

  
 A-10 

 (6) reduce the percentage of Holders necessary to consent to an amendment or
waiver to the Indenture or the Notes; 
 (7) waive a default in the payment of principal of or premium, if any, or interest
on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in the Indenture and a waiver of the payment default that resulted from such acceleration); 

(8) release any Guarantor from any of its obligations under its Guarantee or the Indenture, except as permitted thereunder; or

 (9) make any change in these amendment and waiver provisions. 

It shall not be necessary for the consent of the Holders under Section 9.2 of the Indenture to approve the particular form
of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 (14) Defaults and
Remedies. Each of the following constitutes an Event of Default: 
 (1) failure to pay interest on any of the Notes when
the same becomes due and payable and the continuance of any such failure for 30 days; 
 (2) failure to pay
principal of or premium, if any, on any of the Notes when it becomes due and payable, whether at Stated Maturity, upon redemption, upon purchase, upon acceleration or otherwise; 

(3) failure by the Company or any of its Restricted Subsidiaries to comply with any of their respective agreements or covenants
described in Section 5.1 of the Indenture, or failure by the Issuers to comply in respect of their obligations to make a Change of Control Offer pursuant to Section 4.14 of the Indenture;
