Restricted Subsidiaries; 
 (2) the Net Income of any Restricted Subsidiary shall be excluded to the extent that
the declaration or payment of dividends or similar distributions by that Restricted Subsidiary of that Net Income is not at the date of determination permitted without any prior governmental approval (that has not been obtained) or, directly or

 THE NOTES 
 SECTION 3.01 Designation and Amount. 

The Notes shall be designated as the “6 1/4% Senior Notes due 2022”. The aggregate principal amount of Notes that will be authenticated and delivered under this Supplemental Indenture on the Initial Issuance Date is $450.0 million. Additional
Notes may be issued hereunder in accordance with Section 3.15 hereof. 
 SECTION 3.02 Forms Generally. 

(a) General. The Notes and the Trustee’s certificate of authentication to be borne by the Notes shall be substantially in
the form of Exhibit A hereto. 
 Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends or endorsements as the Officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required to comply with
any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any national securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to
indicate any special limitations or restrictions to which any particular Notes are subject. 
 (b) Global Notes. Notes
issued in global form will be substantially in the form of Exhibit A hereto, including the “Global Note Legend” thereon and the “Schedule of Increases or Decreases in the Global Note” attached thereto). Notes issued in definitive
form will be substantially in the form of Exhibit A hereto, but without the “Global Note Legend” thereon and without the “Schedule of Increases or Decreases in the Global Note” attached thereto. Each Global Note will represent
such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, transfers and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount
of outstanding Notes represented thereby will be made by the Trustee or the Depositary, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 3.07 hereof. 

  
 30 

 The terms and provisions contained in the form of Note attached as Exhibit A shall
constitute, and are hereby expressly made, a part of this Supplemental Indenture. 
 SECTION 3.03 Execution, Authentication, Delivery and
Dating. 
 An Officer of the Company shall sign the Notes on behalf of the Company by manual or facsimile signature. If an
Officer of the Company whose signature is on a Note no longer holds that office at the time the Note is authenticated, such Note shall be valid nevertheless. 
 A Note shall not be entitled to any benefit under the Indenture or the Subsidiary Guarantees or be valid or obligatory for any purpose until authenticated by the manual signature of an authorized
signatory of the Trustee, which signature shall be conclusive evidence that the Note has been authenticated under the Indenture. 
 On the Initial Issuance Date, the Trustee shall authenticate and deliver $450.0 million in aggregate principal amount of the Notes, and at any time and from time to time thereafter, the Trustee shall
authenticate and deliver Notes for original issue that may be validly issued under the Indenture (including any Additional Notes) in an aggregate principal amount specified in any written order of the Company signed by two Officers (an
“Authentication Order”). 
 The Trustee may appoint an authenticating agent acceptable to the Company to
authenticate the Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in the Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as an Agent to deal with the Company, any Guarantor or any other Affiliate of the Company. 

SECTION 3.04 Registrar and Paying Agent. 
 The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented
for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term
“Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. 
 The Company shall notify the Trustee of the name and address of any Agent not a party to the Indenture. The Company may change any Paying Agent or Registrar without notice to any Holder. If the Company
fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any Restricted Subsidiary may act as Paying Agent or Registrar. 

The Company initially appoints The Depository Trust Company or its nominee to act as Depositary with respect to the Global Notes.

  
 31 

 The Company initially appoints the corporate trust office or agency of the Trustee in New
York, New York to act as the Registrar and Paying Agent with respect to the Global Notes. 
 SECTION 3.05 Paying Agent to Hold Money in
Trust. 
 The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will
hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium, if any, or interest, if any, or Additional Amounts, if any, on, the Notes and will notify the Trustee of any
default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon payment over to the Trustee and upon accounting for any funds disbursed, the Paying Agent (if other than the Company, a Guarantor or another
Restricted Subsidiary) shall have no further liability for the money. If the Company or a Restricted Subsidiary 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. Each Paying Agent shall otherwise comply with TIA § 317(b). 
 SECTION 3.06 Holder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and
addresses of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar with respect to the Notes, the Company shall furnish to the Trustee at least five Business Days before each interest payment date with
respect to the Notes, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders, and the Company shall otherwise comply with TIA
§ 312(a). 
 SECTION 3.07 Transfer and Exchange. 
 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary
or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All beneficial interests in the Global Notes will be exchanged by the Company for a Certificated
Note if: 
 (1) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary;
or 
 (2) there has occurred and is continuing an Event of Default, and the Depositary notifies the Trustee of
its decision to exchange the Global Notes for Certificated Notes. 

  
 32 

 In connection with the exchange of all the beneficial interests in a Global Note to
beneficial owners pursuant to this Section 3.07(a), the Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner
identified by the Depositary in exchange for its beneficial interests in the Global Note, an equal aggregate principal amount of Certificated Notes, registered in the names, and issued in any approved denominations, requested by or on behalf of the
Depositary (in accordance with Applicable Procedures). Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.08 and 3.11 hereof. A Global Note may not be exchanged for another Note other than as provided in
this Section 3.07(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 3.07(b) hereof. 
 None of the Company, any Guarantor or the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Notes by the Depositary, or for
maintaining, supervising or reviewing any records of the Depositary relating to the Notes. None of the Company, any Guarantor or the Trustee shall be liable for any delay by the related Holder of the Global Note or the Depositary in identifying the
beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from such Holder or the Depositary for all purposes (including with respect to the registration and delivery, and the respective
principal amounts, of the Certificated Notes to be issued). 
 (b) Transfer and Exchange of Beneficial Interests in the
Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of the Indenture and the Applicable Procedures. Beneficial interests in any Global
Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this
Section 3.07(b). 
 (c) Transfer and Exchange of Certificated Notes for Beneficial Interests. A Holder of a
Certificated Note may exchange such Note for a beneficial interest in a Global Note or transfer such Certificated Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a
request for such an exchange or transfer, the Trustee will cancel the applicable Certificated Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes. 

(d) Transfer and Exchange of Certificated Notes for Certificated Notes. Upon request by a Holder of Certificated Notes and such
Holder’s compliance with the provisions of this Section 3.07(d), the Registrar will register the transfer or exchange of Certificated Notes. Prior to such registration of transfer or exchange, the requesting Holder must present or
surrender to the Registrar the Certificated Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. A Holder of
Certificated Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Certificated Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Certificated Note pursuant to the
instructions from the Holder thereof. 

  
 33 

 (e) Legends. Each Global Note will bear a legend in substantially the following form:

 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT
OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 3.07 OF THE INDENTURE, (2) THIS GLOBAL NOTE
MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 3.07(a) OF THE INDENTURE, (3) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 3.12 OF THE INDENTURE AND (4) THIS GLOBAL NOTE MAY BE
TRANSFERRED TO A SUCCESSOR DEPOSITARY IN ACCORDANCE WITH THE INDENTURE. 
 UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN
DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO
A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) (“DTC”), TO THE COMPANY OR
ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO
CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF,
CEDE & CO., HAS AN INTEREST HEREIN.” 
 (f) Cancellation and/or Adjustment of Global Notes. At such time as
all beneficial interests in a particular Global Note have been exchanged for Certificated Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained
and canceled by the Trustee in accordance with Section 3.12 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Note, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the
Trustee to reflect such reduction, and such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 

(g) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global
Notes and Certificated Notes upon receipt of an Authentication Order in accordance with Section 3.03 hereof or at the Registrar’s request. 

  
 34 

 (2) No service charge shall be made to a Holder for any registration of
transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or
similar governmental charge payable upon exchanges pursuant to Section 3.11, 4.06, 5.10, 5.15 or 10.05). 

(3) All Global Notes and Certificated Notes issued upon any registration of transfer or exchange of Global Notes or
Certificated Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture, as the Global Notes or Certificated Notes surrendered upon such registration of transfer or exchange.

 (4) Neither the Registrar nor the Company will be required: 

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business
15 days before the day of any selection of Notes for redemption under Section 4.02 hereof and ending at the close of business on the day of selection; or 
 (B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

(5) Prior to due presentment for the registration of a transfer of any Note, the Company, any Guarantor, the Trustee, any
Agent and any authenticating agent may treat the Person in whose name any Note is registered as the owner of such Note for the purpose of receiving payments of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on,
such Note and for all other purposes. None of the Company, any Guarantor, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary. Members of, or participants in, the Depositary (“Agent
Members”) shall have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee or the Custodian as its custodian, or under such Global Note, and the Depositary may be treated by the
Company, any Guarantor, the Trustee or the Custodian and any agent of the Company, any Guarantor, the Trustee or the Custodian as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, (i) the
registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder of Notes is entitled to take under the
Indenture or the Notes and (ii) nothing herein shall prevent the Company, any Guarantor, the Trustee or the Custodian, or any agent of the Company, any Guarantor, the Trustee or the Custodian, from giving effect to any written certification,
proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. 

  
 35 

 (6) The Trustee will authenticate Global Notes and Certificated Notes in
accordance with the provisions of Section 3.03 hereof. 
 (7) All certifications, certificates and Opinions
of Counsel required to be submitted to the Registrar pursuant to this Section 3.07 to effect a registration of transfer or exchange may be submitted by facsimile or electronic image scan. 

SECTION 3.08 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee, or if the Holder of a Note claims that such Note has been destroyed, lost or stolen and the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of such Note, the Company shall issue and the Trustee shall authenticate a replacement Note if the Trustee’s requirements are met. If any such mutilated, destroyed, lost or stolen Note has become
or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note. If required by the Trustee, any Guarantor or the Company, such Holder must furnish an indemnity bond that is sufficient in the
judgment of the Trustee and the Company to protect the Company, each Guarantor, the Trustee, any Agent or any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company and the Trustee may charge a Holder for
their expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Company. 

SECTION 3.09 Outstanding Notes. 
 Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note
effected by the Trustee hereunder and those described in this Section 3.09 as not outstanding. 
 If a Note is replaced
pursuant to Section 3.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. 
 If the principal amount of any Note is considered paid under Section 5.01, it ceases to be outstanding and interest on it ceases to accrue. 

A Note does not cease to be outstanding because the Company, a Guarantor or another Affiliate of the Company or an Affiliate of a
Guarantor holds such Note. 
 SECTION 3.10 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, amendment, supplement, waiver or consent, Notes owned by the Company, a Guarantor or any other
obligor upon the Notes or any Affiliate of the Company or a Guarantor or of such other obligor shall be disregarded, except that, for the purpose of determining whether the Trustee shall be protected in relying upon any such direction, amendment,
supplement, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. 

  
 36 

 SECTION 3.11 Temporary Notes. 

Until Certificated Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary
Notes shall be substantially in the form of Certificated Notes, but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Certificated
Notes in exchange for temporary Notes. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under the Indenture as Certificated Notes. 
 SECTION 3.12 Cancellation. 
 The Company or any Guarantor at any time may
deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange, payment or redemption. The Trustee shall cancel all Notes
surrendered for registration of transfer, exchange, payment, redemption, replacement or cancellation. Unless the Company shall direct in writing that canceled Notes be returned to it, after written notice to the Company all canceled Notes held by
the Trustee shall be disposed of in accordance with the usual disposal procedures of the Trustee, and the Trustee shall maintain a record of their disposal. The Company may not issue new Notes to replace Notes that have been paid or that have been
delivered to the Trustee for cancellation. 
 SECTION 3.13 Defaulted Interest. 

If the Company defaults in a payment of interest on the Notes, the Company shall pay the defaulted interest in any lawful manner plus,
to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Notes and in Section 5.01. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At
least 15 days before any special record date selected by the Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20 days’ prior written notice from the Company setting forth such special record date and
the interest amount to be paid) shall mail to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 SECTION 3.14 CUSIP Numbers. 
 The Company in issuing the Notes may use
“CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers and corresponding “ISINs” in notices of redemption as a convenience to the Holders
thereof; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be
placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. 

  
 37 

 SECTION 3.15 Issuance of Additional Notes. 

After the Initial Issuance Date, the Company shall be entitled, subject to its compliance with Section 5.09, to issue Additional
Notes under the Indenture, which shall have identical terms as the Initial Notes issued on the Initial Issuance Date, other than with respect to the date of issuance. With respect to any Additional Notes, the Company shall set forth in a Board
Resolution and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information: 
 (a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to the Indenture; 
 (b) the issue date and the CUSIP number of such Additional Notes; and 
 (c) the
date from which interest shall accrue on such Additional Notes. 
 ARTICLE IV 

REDEMPTION AND PURCHASE 

SECTION 4.01 Notice to the Trustee. 
 If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 4.08 hereof, it shall notify the Trustee of the redemption date and the principal amount of Notes to be
redeemed. The Company shall so notify the Trustee at least 45 days before the redemption date (unless a shorter notice shall be satisfactory to the Trustee) by delivering to the Trustee an Officers’ Certificate stating that such redemption will
comply with the provisions of the Indenture and of the Notes. Any such notice may be canceled at any time prior to the mailing of such notice of such redemption to any Holder and shall thereupon be void and of no effect. 

SECTION 4.02 Selection of Notes to Be Redeemed. 
 If less than all of the Notes are to be redeemed at any time, selection of Notes for redemption will be made by the Trustee on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate or require unless otherwise required by law or applicable stock exchange or depositary requirements. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the
principal amount to be redeemed. A new Note in principal amount equal to the unredeemed portion will be issued in the name of the Holder upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption.

 The Trustee shall promptly notify the Company and the Registrar in writing of the Notes selected for redemption and, in the
case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. No Notes of $2,000 or less in principal amount can be redeemed or purchased in part. Notes and portions of Notes selected will be in amounts of $2,000 or
whole multiples of $1,000 in excess thereof, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. 

  
 38 

 For purposes of this Supplemental Indenture, unless the context otherwise requires, all
provisions relating to redemption of Notes shall relate, in the case of any of the Notes redeemed or to be redeemed only in part, to the portion of the principal amount thereof which has been or is to be redeemed. 

SECTION 4.03 Notice of Redemption. 
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the redemption date, to each Holder whose Notes are to be redeemed at the
address of such Holder appearing in the register of Notes maintained by the Registrar, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or
a satisfaction and discharge of the Indenture pursuant to Articles IX and XII hereto. 
 All notices of redemption shall
identify the Notes to be redeemed and shall state: 
 (1) the redemption date; 

(2) the redemption price (or the method by which it will be calculated); 

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

(4) if any Note is being redeemed in part, the portion of the principal amount of such Note 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 will be issued upon cancellation of the original Note; 

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

(6) the name and address of the Paying Agent; and 

(7) the CUSIP number, if any, relating to the Notes and 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. 
 Notice of redemption of Notes to be redeemed at
the election of the Company shall be given by the Company or, at the Company’s written request, by the Trustee in the name and at the expense of the Company. 

  
 39 

 SECTION 4.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed in accordance with Section 4.03 hereof, Notes called for redemption become irrevocably due and
payable on the redemption date and at the redemption price. Notices of redemption may not be conditional. Upon surrender to the Paying Agent, such Notes called for redemption shall be paid at the redemption price, but interest installments due on or
prior to such redemption date will be payable on the relevant interest payment dates to the Holders of record of such Notes at the close of business on the relevant record dates. 
 SECTION 4.05 Deposit of Redemption Price. 
 On or prior to 11:00 a.m., New
York City time, on any redemption date, the Company or a Guarantor will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption of and accrued interest, if any, on all Notes to be redeemed or on that date. The
Trustee or the Paying Agent will promptly return to the Company or such Guarantor any money deposited with the Trustee or the Paying Agent by the Company or such Guarantor in excess of the amounts necessary to pay the redemption price of and accrued
interest, if any, on all Notes to be redeemed. 
 If the Company or a Guarantor complies with the provisions of the preceding
paragraph, on and after the redemption date, interest will cease to accrue on the Notes or the portions of Notes called for redemption, whether or not such Notes are presented for payment, and the Holders of such Notes shall have no further rights
with respect to such Notes except for the right to receive the redemption price of, accrued interest, if any, and Additional Amounts, if any, on such Notes upon surrender of such Notes. If a Note is redeemed on or after an interest record date but
on or prior to the related interest payment date, then any accrued and unpaid interest and Additional Amounts, if any, 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 is not so paid upon surrender for redemption because of the failure of the Company or a Guarantor to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such
principal is paid, and to the extent lawful, on any interest and Additional Amounts, if any, not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 5.01 hereof. 

SECTION 4.06 Notes Redeemed in Part. 
 Upon surrender of a Note that is redeemed in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder of such Note at the expense of the
Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 
 SECTION 4.07 Purchase of Notes.

 The Company, any Guarantor or any Affiliate of the Company or any Guarantor may, subject to applicable law, at any time
purchase or otherwise acquire Notes in the open market or by private agreement. Any such acquisition shall not operate as or be deemed for any purpose to be a redemption of the indebtedness represented by such Notes. Any Notes purchased

  
 40 

 
or acquired by the Company or a Guarantor may be delivered to the Trustee and, upon such delivery, the indebtedness represented thereby shall be deemed to be satisfied. Section 3.12 shall
apply to all Notes so delivered. 
 SECTION 4.08 Optional Redemption. 

(a) On and after October 15, 2017, the Notes will be subject to redemption on one or more occasions at the option of the Company, in
whole or in part at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Amounts, if any, to the applicable redemption date (subject to the rights of Holders of the
Notes on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period beginning on October 15 of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2017
	  	 	103.125	% 
	 2018
	  	 	102.083	% 
	 2019
	  	 	101.042	% 
	 2020 and thereafter
	  	 	100.000	% 

 On or prior to October 15, 2015, the Company may on one or more occasions redeem up to 35% of the
aggregate principal amount of Notes (including any Additional Notes issued after the Initial Issuance Date) at a redemption price equal to 106.250% of the principal amount of the Notes redeemed, plus accrued and unpaid interest and Additional
Amounts, if any, to the redemption date (subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date), with the net cash proceeds of one or more Qualified Equity Offerings,
provided that: 
 (1) at least 65% of the aggregate principal amount of Notes (including any Additional Notes)
issued remains outstanding immediately after the occurrence of each such redemption; and 
 (2) each such
redemption occurs within 180 days of the date of the closing of each such Qualified Equity Offering. 
 Prior to
October 15, 2017, the Company may at its option on one or more occasions redeem all or part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid
interest and Additional Amounts, if any, to, the redemption date (subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date). 

(b) The Company (which, for the purposes of this Section 4.08(b) refers to a Person succeeding the Company that is organized or
existing in a Permitted Foreign Jurisdiction) may redeem the Notes, in whole but not in part, at its discretion at any time upon giving not less than 30 nor more than 60 days’ prior notice to the Holders of the Notes (which notice will be
irrevocable and given in accordance with the procedures described in Section 4.03 hereof), at a 

  
 41 

 
redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to the date fixed by us for redemption (a “Tax Redemption
Date”) and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise (subject to the rights of Holders of the Notes on the relevant record date to receive
interest due on the relevant interest payment date and Additional Amounts, if any, in respect thereof), if on the next date on which any amount would be payable in respect of the Notes, the Company is or would be required to pay Additional Amounts,
and the Company cannot avoid any such payment obligation by taking reasonable measures available (including, for the avoidance of doubt, the appointment of a new paying agent), and the requirement arises as a result of: 

(1) any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the relevant Tax
Jurisdiction affecting taxation, which change or amendment has not been publicly announced before and which becomes effective on or after the date on which the Tax Jurisdiction imposing the relevant withholding or deduction became the applicable Tax
Jurisdiction under the Indenture; or 
 (2) any change in, or amendment to, the existing official position
regarding the application, administration or interpretation of such laws, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction or a change in published practice), which change, amendment, application or
interpretation has not been publicly announced before and becomes effective on or after the date on which the Tax Jurisdiction imposing the relevant withholding or deduction became the applicable Tax Jurisdiction under the Indenture). 

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

The Company will not give any such notice of redemption earlier than 60 days prior to the earliest date on which it would be obligated
to make such payment or withholding if a payment in respect of the Notes were then due, and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Prior to the publication or, where relevant, mailing of any
notice of redemption of the Notes pursuant to the foregoing, the Company will deliver to the Trustee an opinion of independent tax counsel, the choice of such counsel to be subject to the prior written approval of the Trustee (such approval not to
be unreasonably withheld) to the effect that there has been such change or amendment which would entitle the Company to redeem such Notes hereunder. In addition, before the Company publishes or mails notice of redemption of the Notes, it will
deliver to the Trustee an Officers’ Certificate to the effect that it cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. 

The Trustee will accept, and will be entitled to rely solely on, such Officers’ Certificate and Opinion of Counsel as conclusive
proof of the existence and satisfaction of the conditions precedent as described in the immediately preceding paragraph, in which event such satisfaction of the conditions precedent will be conclusive and binding on the Holders. 

  
 42 

 For the avoidance of doubt, the implementation of European Council Directive 2003/48/EC or
any other directive implementing the conclusions of the ECOFIN Council meeting of 26 and 27 November 2000 on the taxation of savings income or any law implementing or complying with or introduced in order to conform to, such directive will not
be a change or amendment for such purposes. 
 (c) Any redemption pursuant to this Section 4.08 shall be made pursuant to
the provisions of Sections 4.01 through 4.06 hereof. 
 SECTION 4.09 Mandatory Redemption. 

Except as set forth under Section 5.10 and Section 5.15, the Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders. 
 SECTION 4.10 Offer to Purchase by
Application of Excess Proceeds. 
 In the event that, pursuant to Section 5.10 hereof, the Company is required to
commence an Asset Sale Offer to all Holders to purchase Notes and, to the extent required by the terms of the Pari Passu Notes, to all holders of Pari Passu Notes, it will follow the procedures specified below. 

The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business
Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will
apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and Pari Passu Notes as specified in Section 5.10(d) or, if less than the Offer Amount has been tendered, all Notes and Pari Passu Notes validly tendered
and not withdrawn in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to each of the Holders, with a copy to the Trustee. The notice will contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which will govern the terms of the Asset Sale Offer, will state: 

(1) that the Asset Sale Offer is being made pursuant to this Section 4.10 and Section 5.10 hereof and the
length of time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase price and the
Purchase Date; 
 (3) that any Note not properly tendered or accepted for payment will continue to accrue
interest and Additional Amounts, if any; 

  
 43 

 (4) that, unless the Company defaults in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest and Additional Amounts, if any, on and after the Purchase Date; 
 (5) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to
the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to the end of the Offer Period; 

(6) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the
case may be, receives, not later than the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is
withdrawing his election to have such Note purchased; 
 (7) that, if the aggregate principal amount of Notes
surrendered by Holders thereof and other Pari Passu Notes surrendered by Holders or lenders, collectively, exceeds the Offer Amount, the Trustee shall select the Notes and Pari Passu Notes to be purchased on a pro rata basis on the basis of
the aggregate principal amount of tendered Notes and Pari Passu Notes (except that any Notes represented by a Note in global form will be selected by such method as the Depositary or its nominee or successor may require or, where the nominee or
successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be redeemed (with such adjustments as may be deemed appropriate by
the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and 
 (8) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer),
which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent
necessary, the principal amount of Notes or portions thereof required to be purchased pursuant to this Section 4.10 (or, if less than the Offer Amount has been tendered, all Notes tendered), and will deliver or cause to be delivered to the
Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.10. The Company, a Guarantor,
the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted
by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder, in
a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer
on the Purchase Date.

 ARTICLE V 
 COVENANTS 
 SECTION 5.01 Payment of Notes. 

The Company shall pay the principal of, and premium, if any, interest, if any, and Additional Amounts, if any, on, the Notes on the
dates and in the manner provided in the Notes. Principal, premium, if any, interest, if any, and Additional Amounts, if any, shall be considered paid on the date due if the Paying Agent (other than the Company, a Guarantor or other Restricted
Subsidiary) holds as of 11:00 a.m. New York time on that date money deposited by the Company or a Guarantor designated for and sufficient to pay all principal, premium, if any, interest, if any, and Additional Amounts, if any then due. Subject to
Section 5.16, all payments made by the Company under or with respect to the Notes will be made free and clear of and without withhold or reduction for, or on account of, any Taxes (as used and defined in Section 5.16 hereof), unless the
withholding or deduction of such Taxes is then required by law. 
 The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal, at a rate equal to the then applicable interest rate on the Notes to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under
any Bankruptcy Law) on overdue installments of interest, if any, and Additional Amount, if any, (without regard to any applicable grace period) at the same rate to the extent lawful. 
 SECTION 5.02 Maintenance of Office or Agency. 
 The Company will maintain
in the Borough of Manhattan, The City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, the Registrar or the Paying Agent) where Notes may be surrendered for registration of transfer or for
exchange, where Notes may be presented for payment and where notices and demands to or upon the Company or a Guarantor in respect of the Notes and the Indenture may be served; provided, however that the Company may, at its option, pay
interest on the Notes by check mailed to Holders of the Notes at their registered address as it appears in the Registrar’s books. The Company will give prompt written notice to the Trustee and the Guarantors of the location, and any change in
the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee and the Guarantors with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Trustee. 
 The Company may also from time to time
designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

 SECTION 5.03 Reports;
Financial Statements. 
 (a) Notwithstanding that the Company may not be subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, the Company will furnish to the Trustee and the Holders of Notes (or, to the extent permitted by the Commission, file with the Commission for public availability), within the time periods specified in
the Commission’s rules and regulations, taking into account any extension of time, deemed filing date or safe harbor contemplated or provided for by Rule 12b-25 under the Exchange Act:

and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants; and 
 (2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports. 

So long as the Company is required to file periodic reports under Section 13(a) or Section 15(d) of the Exchange Act, the
Company’s obligation to deliver the information referred to above shall be deemed satisfied upon the filing such information with the Commission using the EDGAR system and such information is publicly available. 

(b) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, and such Unrestricted Subsidiaries’ total
assets (determined in accordance with GAAP) as of the end of the most recently completed fiscal year exceed an amount equal to 5% of the consolidated total assets of the Company and its Restricted Subsidiaries, then the quarterly and annual
financial information required by Section 5.03(a) shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial statements 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 separate from the financial condition and results of operations of the Unrestricted
Subsidiaries.

 46 

 
the activities of the Company during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company or such Guarantor, as the

fulfilled each and every covenant contained in the Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default has occurred, describing all such
Defaults or Events of Default of which such Officer may have knowledge and what action the Company or such Guarantor, as the case may be, is taking or proposes to take with respect thereto). 

(b) The Company or any Guarantor shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer
of the Company or such Guarantor, as the case may be, becoming aware of any Default or Event of Default under this Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the Company or such Guarantor, as
the case may be, is taking or proposes to take with respect thereto. 
 SECTION 5.05 Taxes. 

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

SECTION 5.06 Waiver of Stay, Extension and Usury Laws. 
 Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will 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 the Indenture; and each of the Company and the Guarantors (to the extent that it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law has been enacted. 
 SECTION 5.07 Limitation on Restricted Payments. 

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

or would occur as a consequence thereof; 
 (B) the Company would, at the time of such Restricted Payment and
after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to Section 5.09(a); and

 (C) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the

 (b) The preceding provisions of this
Section 5.07 will not prohibit any of the following:

 (2) the making of any Restricted Payment in exchange for, or out of or with
the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of other Equity Interests of, the Company (other than any Disqualified Stock and other than Equity Interests issued or sold to a Subsidiary of the
Company or an employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or guaranteed by the Company or any Restricted Subsidiary unless such loans have been
repaid with cash on or prior to the date of determination), or from the substantially concurrent contribution of common equity capital to the Company, with a sale or contribution being deemed substantially concurrent if such Restricted Payment
occurs not more than 120 days after such sale or contribution; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment shall be excluded from clause (C)(ii) of Section 5.07(a); 

  
 50 

 (3) the defeasance, redemption, repurchase, retirement or other acquisition
of Indebtedness subordinated to the Notes or the Subsidiary Guarantees with the net cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness;

(5) so long as no Default or Event of Default shall have occurred and be continuing, the repurchase, redemption or other
acquisition or retirement for value of any Equity Interests of the Company held by any current or former employee, officer or director of the Company or any of its Restricted Subsidiaries; provided that the aggregate price paid for all such

added to such amount) plus, to the extent not previously applied or included, (i) the net cash proceeds received by the Company or any of its Restricted Subsidiaries from sales of Equity Interests (other than Disqualified Stock) to
employees or directors of the Company or its Restricted Subsidiaries that occur after the Initial Issuance Date (to the extent the cash proceeds from the sale of such Equity Interests have not otherwise been applied to the payment of Restricted

(6) the purchase, redemption or other acquisition or retirement for value of (i) Equity Interests by the Company in
connection with the exercise of stock options, stock appreciation rights, warrants or other rights to acquire Equity Interests by way of cashless exercise or (ii) Equity Interests of the Company or any Restricted Subsidiary of the Company held
by any current or former officers, directors or employees of the Company or any of its Restricted Subsidiaries in connection with the exercise or vesting of any equity compensation (including, without limitation, stock options, restricted stock and

(7) any purchase, redemption, defeasance or other acquisition or retirement of any Indebtedness subordinated to the Notes
or the Subsidiary Guarantees from Net Proceeds from an Asset Sale or in the event of a Change of Control, in each case only if prior to or simultaneously with such purchase, redemption, defeasance or other acquisition or retirement, the Company has
made the Asset Sale Offer or Change of Control Offer, as applicable, as provided Section 5.10 or Section 5.15 as applicable, with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment
in connection with such Asset Sale Offer or Change of Control Offer; 

  
 51 

 (8) cash payments in lieu of the issuance of fractional shares; 

(9) other Restricted Payments in an aggregate amount not to exceed the greater of (i) $75.0 million and
(ii) 2.5% of Consolidated Net Tangible Assets, determined as of the date each such Restricted Payment is made. 
 For
purposes of determining compliance with this Section 5.07, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in clauses (1)-(9) of Section 5.07(b) or as a
Permitted Investment, the Company will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section. 

(c) The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a
Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time
of such designation. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the Fair Market Value of such Investments at the time of such designation. Such designation will only be permitted if such
Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the
Company or any Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this covenant will be determined, in the case of amounts under $40.0
million, by an Officer of the Company and, in the case of amounts greater than or equal to $40.0 million, by the Board of Directors of the Company, whose resolution with respect thereto will be delivered to the Trustee. 

SECTION 5.08 Limitation on Dividends and Other Payment Restrictions Affecting Subsidiaries. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or suffer to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) (i) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or (ii) pay any Indebtedness or other obligations owed to the Company
or any of its Restricted Subsidiaries; 
 (2) make loans or advances to the Company or any of its Restricted
Subsidiaries; or 
 (3) transfer any of its properties or assets to the Company or any of its Restricted
Subsidiaries.

 (b) The provisions of Section 5.09(a) will not prohibit encumbrances or restrictions

 (1) (i) agreements governing the Credit Facilities, any instrument
governing Existing Indebtedness or any other agreement or instrument, each as in effect on the Initial Issuance Date, (ii) agreements governing Indebtedness permitted to be incurred under Section 5.09, and (iii) any amendments,
restatements, modifications, renewals, increases, supplements, refundings, replacements or refinancings of the agreements and instruments referred to in clauses (i) and (ii) or the Indebtedness to which those agreements relate; provided
that, in the case of clauses (ii) and (iii), the encumbrances and restrictions therein are not materially more restrictive, taken as a whole, than those contained in (x) the Indenture and the Notes or (y) agreements or instruments in
effect on the Initial Issuance Date, in each case as determined by the Company in its reasonable and good faith judgment; 
 (2) the Indenture and the Notes; 
 (3) applicable law, rule,
regulation or order or similar restriction; 
 (4) any agreement or instrument governing Indebtedness or Capital
Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was
permitted by the terms of the Indenture to be incurred; 
 (5) customary non-assignment provisions in contracts
and leases entered into in the ordinary course of business and consistent with past practices; 
 (6) any
mortgages, pledges or other security agreements permitted under the Indenture securing Indebtedness of the Company or a Restricted Subsidiary to the extent the encumbrances or restrictions they contain restrict the transfer of the properties or
assets subject to such mortgages, pledges or other security agreements; 
 (7) agreements governing purchase
money obligations, mortgage financings and Capital Lease Obligations incurred in compliance with Section 5.09, in each case that impose encumbrances or restrictions of the nature described in clause (3) of Section 5.08(a) on the
properties or assets financed thereby; 
 (8) any encumbrance or restriction with respect to a Restricted
Subsidiary (or any of its properties or assets) imposed pursuant to an agreement entered into for the direct or indirect sale or disposition of all or substantially all the Capital Stock or properties or assets of such Restricted Subsidiary (or the
properties or assets that are subject to such restriction) pending the closing of such sale or disposition; 

  
 53 

 (9) customary provisions in bona fide contracts for the sale of properties
or assets; 
 (10) customary provisions in joint venture agreements and similar agreements that restrict the
transfer of interests in the joint venture; 
 (11) provisions limiting the disposition or distribution of
assets or property in joint venture agreements, asset sale agreements, agreements governing Sale/Leaseback Transactions, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted
Investment) entered into (i) in the ordinary course of business or (ii) with the approval of the Company’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements; 

(12) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers or required by insurance,
surety or bonding companies, in each case under contracts entered into in the ordinary course of business; 

(13) encumbrances or restrictions with respect to property under a charter, lease or other agreement that has been
entered into in the ordinary course for the employment, charter or other hire of such property; 
 (14) any
agreement or instrument relating to any property or assets acquired after Initial Issuance Date in effect at the time of such acquisition, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and
was not created in anticipation of such acquisition; 
 (15) the issuance of Preferred Stock by a Restricted
Subsidiary of the Company or the payment of dividends thereon in accordance with the terms thereof; provided that the terms of such Preferred Stock do not expressly restrict the ability of a Restricted Subsidiary of the Company to pay
dividends or make any other distributions on its Equity Interests (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such other Equity
Interests); and 
 (16) agreements governing Permitted Refinancing Indebtedness; provided that the restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined by the Company in
its reasonable and good faith judgment. 
 SECTION 5.09 Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock.

 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur,
issue, assume, guarantee or otherwise become 

  
 54 

 
directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur” or an “incurrence”) any Indebtedness, the Company will not, and
will not permit any Guarantor to, issue any Disqualified Stock and the Company will not permit any of its Restricted Subsidiaries that are not Guarantors to issue any shares of Preferred Stock; provided, however, that the Company and
its Restricted Subsidiaries may incur Indebtedness, the Company and any Guarantor may issue Disqualified Stock, and any Restricted Subsidiaries of the Company that are not Guarantors may issue any shares of Preferred Stock, if the Consolidated
Interest Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified
Stock or Preferred Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness, Disqualified Stock or Preferred Stock had
been incurred or issued, as the case may be, at the beginning of such four-quarter period. 
 (b) The provisions of
Section 5.09(a) will not prohibit: 
 (1) the incurrence by the Company and its Restricted Subsidiaries of
Indebtedness under Credit Facilities in an aggregate principal amount at any one time outstanding not to exceed the greater of (i) $750.0 million (or the equivalent thereof in any other currency or currency unit) and (ii) 30% of
Consolidated Net Tangible Assets, determined as of the date of each such incurrence; 
 (2) the incurrence by
the Company and its Restricted Subsidiaries of Existing Indebtedness; 
 (3) the incurrence by the Company and
its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business and not for speculation; 

(4) the incurrence by the Company and its Restricted Subsidiaries of Indebtedness represented by the Notes (other than
Additional Notes), the Subsidiary Guarantees and the Indenture; 
 (5) guarantees by the Company or any
Restricted Subsidiary of Indebtedness of the Company or any Restricted Subsidiary incurred in accordance with the provisions of the Indenture; 
 (6) the incurrence of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries, provided that any subsequent issuance or transfer of Equity Interests that
results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company, or any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of
the Company, shall be deemed to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, provided, however: 

(A) if the Company is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness is expressly
subordinated to the prior payment in full in cash of all obligations with respect to the Notes; 

  
 55 

 (B) if a Guarantor is the obligor on such Indebtedness and the Company or a
Guarantor is not the obligee, such Indebtedness is expressly subordinated in right of payment to the Subsidiary Guarantee of such Guarantor, 
 (7) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance or surety bonds issued for the account of the Company or any Restricted Subsidiary
thereof in the ordinary course of business, including guarantees or obligations of the Company or any Restricted Subsidiary thereof with respect to letters of credit supporting such bid, performance or surety obligations (in each case other than for
an obligation for money borrowed); 
 (8) the incurrence by the Company or any of its Restricted Subsidiaries of
Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness that was permitted by the Indenture to be incurred (other than pursuant to clause (1),
(6), (11) and (14) of this Section 5.09(b)); 
 (9) the incurrence by the Company or any of its
Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations with respect to assets other than Capital Stock or other Investments, in each case incurred for the purpose of
financing all or any part of the purchase price or cost of design, construction, installation or improvement of property used in the business of the Company or such Restricted Subsidiary in an aggregate principal amount at any one time outstanding
not to exceed the greater of (i) $125.0 million and (ii) 5% of Consolidated Net Tangible Assets, determined as of the date of each such incurrence; 
 (10) Indebtedness of a Restricted Subsidiary outstanding on the date on which such Restricted Subsidiary, or assets relating to such Indebtedness, were acquired by the Company or any of its Restricted
Subsidiaries, or Indebtedness incurred by the Company or a Restricted Subsidiary to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Restricted Subsidiary becomes
a Restricted Subsidiary or is otherwise acquired by, or such assets are acquired by, the Company or any of its Restricted Subsidiaries; provided, however, that at the time such Restricted Subsidiary is acquired by the Company or on the
date of such asset acquisition, as applicable, the Consolidated Interest Coverage Ratio for the Company’s most recent four quarters for which internal financial statements are available, after giving pro forma effect to the acquisition and the
incurrence of any related Indebtedness, would be (i) at least 2.0 to 1.0 or (ii) equal to or greater than the Consolidated Interest Coverage Ratio determined for such four quarter period without giving effect to such acquisition and
incurrence of Indebtedness; 
 (11) Indebtedness arising from agreements of the Company or a Restricted
Subsidiary providing for indemnification, adjustment of purchase price, holdbacks, earn outs or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, assets or Capital Stock of a
Restricted 

  
 56 

 
Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted
Subsidiaries in connection with such disposition; 
 (12) Indebtedness arising from the honoring by a bank or
other financial institution of a check, draft or similar instrument (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; 

(13) the incurrence by the Company or its Restricted Subsidiaries of Indebtedness consisting of the financing of
insurance premiums in customary amounts consistent with the operations and business of the Company and the Restricted Subsidiaries; and 
 (14) in addition to the items referred to in clauses (1) through (13) above, the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate
principal amount which, when taken together with the aggregate principal amount of all other Indebtedness incurred pursuant to this clause (14) and then outstanding, will not exceed the greater of (i) $300.0 million and (ii) 12% of
Consolidated Net Tangible Assets, determined as of the date of each such incurrence. 
 (c) The Company will not, and will not
permit any Guarantor to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or of such Guarantor, as the case may
be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Notes or the Subsidiary Guarantee of such Guarantor, as the case may be, on substantially the same
terms as such Indebtedness is subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Company or of such Guarantor, as the case may be. 

(d) For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness incurred pursuant
to and in compliance with, this Section 5.09: 
 (1) in the event that Indebtedness meets the criteria of
more than one of the categories of Indebtedness described in Section 5.09(b) or is entitled to be incurred pursuant to Section 5.09(a), the Company, in its sole discretion, will be permitted to divide or classify such item of Indebtedness
on the date of incurrence (or later classify, redivide or reclassify such Indebtedness, in its sole discretion), in any manner that complies with this Section 5.09; 

(2) any Indebtedness under Credit Facilities on the Initial Issuance Date shall be considered incurred under
Section 5.09(b)(1); 
 (3) guarantees of, or obligations in respect of letters of credit relating to,
Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included; 

  
 57 

 (4) the principal amount of any Disqualified Stock of the Company or a
Guarantor will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) and the liquidation preference thereof; 

(5) Indebtedness permitted by this Section 5.09 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 5.09 permitting such Indebtedness; 

(6) 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; and 
 (7) the reclassification
of any lease or other liability of the Company or any of its Restricted Subsidiaries as Indebtedness due to a change of accounting principles after the Initial Issuance Date will not be deemed an incurrence of Indebtedness for purposes of this
covenant. 
 Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of
additional Indebtedness and the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness for purposes of this Section 5.09. The amount of any
Indebtedness outstanding as of any date shall be (1) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (2) the principal amount or liquidation preference thereof, together with any interest
thereon that is more than 30 days past due, in the case of any other Indebtedness. 
 The Company will not permit any of its
Unrestricted Subsidiaries to incur any Indebtedness, other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted
Subsidiary of the Company as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under this Section 5.09, the Company shall be in Default of this Section 5.09). 

For purposes of determining compliance with any Dollar-denominated restriction on the incurrence of Indebtedness, the U.S. Dollar
Equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first
committed, in the case of 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 Dollar-dominated restriction
to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such Dollar-dominated 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. Notwithstanding any other provision of this Section 5.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur
pursuant to this Section 5.09 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. 

  
 58 

 SECTION 5.10 Limitation on Asset Sales. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale
at least equal to the Fair Market Value (provided such Fair Market Value shall be determined (i) as of the date of contractually agreeing to such Asset Sale and (ii) in good faith by an Officer of the Company or, if the consideration with
respect to such Asset Sale exceeds $40.0 million, the Board of Directors of the Company) of the assets or Equity Interests issued or sold or otherwise disposed of; and 

(2) at least 75% of the aggregate consideration received by the Company or its Restricted Subsidiaries in the Asset Sale
and all other Asset Sales since the Initial Issuance Date is in the form of cash, Cash Equivalents or Marketable Securities; provided, however, that the amount of: 

(A) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of
the Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a customary
novation or assumption agreement that releases the Company or such Restricted Subsidiary from further liability shall be deemed to be cash for purposes of this provision; and 

(B) any securities, notes or other obligations (other than Marketable Securities) received by the Company or such
Restricted Subsidiary from such transferee that are converted within 180 days after such Asset Sale by the Company or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion) shall be deemed to be cash for
purposes of this provision; 
 provided that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar taking,
including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of items (1) and (2) of this Section 5.10(a). 
 (b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any such Restricted Subsidiary may apply such Net Proceeds to any combination of the following: 

(1) permanently repay the principal of any senior Indebtedness of the Company or any Restricted Subsidiary; or

  
 59 

 (2) to acquire or invest in (including by way of a purchase of assets or
stock, merger, consolidation or otherwise) Productive Assets or to make a capital expenditure; provided that the requirements of this clause (2) will be deemed to be satisfied if an agreement committing to make the acquisitions, investments or
expenditures referred to above is entered into by the Company or any of its Restricted Subsidiaries within 365 days after the receipt of such Net Proceeds with the good faith expectation that such Net Proceeds will be applied to satisfy such
commitment in accordance with such agreement within 180 days after such 365-day period, and if such Net Proceeds are not so applied within such 180-day period, then such Net Proceeds will constitute Excess Proceeds (as defined below). 

(c) Pending the final application of any such Net Proceeds, the Company or any such Restricted Subsidiary may temporarily reduce
outstanding revolving credit borrowings, including borrowings under the Credit Facilities, or otherwise invest such Net Proceeds in any manner that is not prohibited by the Indenture. 

(d) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 5.10(b) will be deemed to constitute
“Excess Proceeds”. On the 366th day after the Asset Sale (or, at the Company’s option, such earlier date), if the aggregate amount of Excess Proceeds exceeds $50.0 million, the Company will be required to make an offer (an
“Asset Sale Offer”) to all Holders of Notes and, to the extent required by the terms of other Pari Passu Indebtedness, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Company to make
an offer to purchase such Pari Passu Indebtedness with the proceeds from any Asset Sale (“Pari Passu Notes”), to purchase the maximum principal amount of Notes and any such Pari Passu Notes to which the Asset Sale Offer applies that
may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes and Pari Passu Notes, plus accrued and unpaid interest and Additional Amounts, if any, to the date of purchase, in
accordance with the procedures set forth in Section 4.10 hereof or the agreements governing the Pari Passu Notes, as applicable. To the extent that the aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is less than
the amount that the Company is required to repurchase, the Company may use any remaining Excess Proceeds for any purpose not prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof and other Pari Passu
Notes surrendered by holders or lenders, collectively, exceeds the amount that the Company is required to repurchase, the Trustee shall select the Notes and Pari Passu Notes to be purchased on a pro rata basis on the basis of the aggregate
principal amount of tendered Notes and Pari Passu Notes (except that any Notes represented by a Note in global form will be selected by such method as the Depositary or its nominee or successor may require or, where the nominee or successor is the
Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be redeemed (with such adjustments as may be deemed appropriate by the Company so that
only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 

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

  
 60 

 The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with
provisions of this Section 4.10 or Section 5.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 or Section 5.10 by
virtue of compliance with such laws and regulations. 
 SECTION 5.11 Limitation on Transactions with Affiliates. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any properties or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $5.0 million, unless: 

(1) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant
Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary in arm’s-length dealings with an unrelated Person or, if there is no such comparable transaction, on terms
that are fair and reasonable to the Company or such Restricted Subsidiary; and 
 (2) the Company delivers to
the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above; and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $50.0 million, in addition to the Officers’ Certificate referred to above in clause (A), a resolution of the Board of Directors of the Company approved by a majority of the disinterested members thereof; 

provided that the requirements of clause (2) above are not applicable to any Affiliate Transactions in the ordinary course of business with
an Affiliate engaged in the business of providing helicopter transportation services to the oil and gas industry or helicopter search and rescue services (or a business that is reasonably complementary or related to the foregoing). 

(b) The following shall be deemed not to be Affiliate Transactions and, therefore, will not be subject to the provisions of
Section 5.11(a): 
 (1) any employment agreement, employee benefit plan, any other employee compensation
plan or arrangement, officer or director indemnification agreement, severance agreement, consulting agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business, and
payments, awards, grants or issuance of securities pursuant thereto; 

  
 61 

 (2) transactions between or among the Company and its Restricted
Subsidiaries; 
 (3) Permitted Investments and Restricted Payments that are permitted by the provisions of the
Indenture; 
 (4) loans or advances to officers, directors and employees of the Company or any Restricted
Subsidiary made in the ordinary course of business and consistent with past practices of the Company and its Restricted Subsidiaries in an aggregate amount not to exceed $2.0 million outstanding at any one time; 

(5) customary compensation, indemnification and other benefits made available to officers, directors, employees or
consultants of the Company or a Restricted Subsidiary or Affiliate of the Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance; 

(6) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company
solely because the Company owns, directly or indirectly, an Equity Interest in, or otherwise controls, such Person; 
 (7) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee an opinion addressed to the Company or such Restricted Subsidiary, as the case
may be, from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements
of clause (1) of Section 5.11(a); 
 (8) sales of Equity Interests (other than Disqualified Stock) to,
or receipt of capital contributions from, Affiliates of the Company; and 
 (9) transactions pursuant to
agreements or arrangements in effect on the Initial Issuance Date that are described in the prospectus supplement, the accompanying prospectus or the documents incorporated by reference herein and therein, or any amendment, modification, or
supplement thereto or replacement thereof, as long as such agreement or arrangement, as so amended, modified, supplemented or replaced, is not materially more disadvantageous to the Company and its Restricted Subsidiaries, taken as a whole, than the
agreement or arrangement in existence on the Issuance Date. 

  
 62 

 SECTION 5.12 Limitation on Liens. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien on any property or asset now owned or hereafter acquired, except Permitted Liens, to secure (1) any Indebtedness of the Company or such Restricted Subsidiary (if it is not also a Guarantor), unless prior to, or
contemporaneously therewith, the Notes are equally and ratably secured, or (2) any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantees are equally and ratably secured; provided,
however, that if such Indebtedness is expressly subordinated to the Notes or the Subsidiary Guarantees, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Notes or the Subsidiary Guarantees, as the
case may be, with the same relative priority as such Indebtedness has with respect to the Notes or the Subsidiary Guarantees. 

(b) Any Lien on any property or assets of the Company or any of its Restricted Subsidiaries created for the benefit of the Holders of
the Notes pursuant to Section 5.12(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged at such time as there are no other Liens of any kind, except Permitted Liens, on such property or
assets securing Indebtedness. 
 SECTION 5.13 Additional Subsidiary Guarantees. 

If (1) the Company or any of its Restricted Subsidiaries shall, after the Initial Issuance Date, acquire or create another
Significant U.S. Subsidiary or (2) after the Initial Issuance Date, any Restricted Subsidiary that is not a Guarantor shall incur any Indebtedness (including any guarantee of Indebtedness of the Company) except Permitted Non-Guarantor
Indebtedness, then such newly acquired or created Significant U.S. Subsidiary, in the case of clause (1) above, or such Restricted Subsidiary described in clause (2) above, shall, within 30 days thereof, execute a supplement to the
Indenture providing for a Subsidiary Guarantee and deliver an Opinion of Counsel in accordance with the terms of the Indenture. 
 SECTION 5.14
Corporate Existence. 
 Subject to Article VI, the Company shall do or cause to be done all things necessary to preserve
and keep in full force and effect its existence. 
 SECTION 5.15 Offer to Repurchase Upon Change of Control. 

(a) If a Change of Control Trigger Event occurs, the Company will make an offer (a “Change of Control Offer”) to
repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at an offer price in cash equal to 101% of the aggregate principal amount, plus accrued and unpaid interest and Additional
Amounts, if any, to the date of repurchase (the “Change of Control Payment”). Within 30 days following a Change of Control Trigger Event, the Company will mail a notice to each Holder and the Trustee describing the transaction that
constitutes the Change of Control Trigger Event and stating: 
 (1) that the Change of Control Offer is being
made pursuant to this Section 5.15 and that all Notes or portions thereof properly tendered and not withdrawn will be accepted for payment; 

  
 63 

 (2) the Change of Control Payment and the purchase date, which shall be no
earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not properly tendered will continue to accrue interest and Additional Amounts, if any; 
 (4) that if the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued and unpaid interest and Additional Amounts, if
any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no other interest will be payable to Holders who tender pursuant to the Change of Control Offer; 

(5) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer will cease to accrue interest on and after the Change of Control Payment Date; 
 (6) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase”
attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the Change of Control Payment Date; 

(7) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of
business on the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the
Notes purchased; and 
 (8) that Holders whose Notes are being purchased only in part will be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control Trigger Event. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section 5.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described in this Section 5.15 by virtue of compliance with
such laws and regulations. 
 On or before the Change of Control Payment Date, the Company will, to the extent lawful:
(1) accept for payment all Notes or portions thereof properly tendered and not 

  
 64 

 
withdrawn pursuant to the Change of Control Offer; (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all such Notes or portions thereof so
tendered and not withdrawn; and (3) 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
Company. 
 (b) The Paying Agent will promptly mail to each Holder of Notes properly tendered and not withdrawn the Change of
Control Payment for such Notes (or if all Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new
Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The
Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. If the Change of Control Payment Date is on or after an interest payment record date and on or before
the related interest payment date, any accrued and unpaid interest and Additional Amounts, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no other interest will be payable to
Holders who tender pursuant to the Change of Control Offer. 
 Payment of the Change of Control Payment for a Note properly
tendered and not withdrawn prior to the expiration of the Change of Control Offer is conditioned upon delivery of such Note (together with necessary endorsements) to the Paying Agent (whether prior to, on or after the Change of Control Payment
Date), which delivery may be in book-entry form in accordance with the Applicable Procedures for Notes issued in global form. The Change of Control Payment for such Note will be made promptly following the later of the Business Day following the
Change of Control Payment Date or the time of delivery of such Note. 
 (c) Notwithstanding anything to the contrary in this
Section 5.15, the Company will not be required to make a Change of Control Offer following a Change of Control Trigger Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance
with the requirements set forth in this Section 5.15 and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption with respect to all outstanding Notes has been given pursuant to
Section 4.08 unless and until there is a default in payment of the applicable redemption price. 
 (d) In the event that
not less than 90% of the aggregate principal amount of the then outstanding Notes are properly tendered and not withdrawn under a Change of Control Offer and the Company purchases all such Notes, the Company will have the right, upon not less than
30 nor more than 60 days’ prior notice, given not more than 30 days following the Change of Control Payment Date, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control
Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, to the 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). Sections 4.01, 4.03, 4.04 and 4.05 shall be applicable to any such redemption.

 SECTION 5.16 Payment of Additional Amounts by a Foreign Successor Issuer. 

(a) In the event that the Company is succeeded by an entity organized or existing in a Permitted Foreign Jurisdiction as permitted by
Section 6.01 and if any deduction or withholding for, or on account of, any Taxes (as defined below) imposed or levied by or on behalf of (1) any jurisdiction in which the Company (which, for purposes of this Section, refers to the Person
succeeding the Company) or any Guarantor, is then incorporated, engaged in business, organized or otherwise resident or treated as resident for tax purposes or any political subdivision thereof or therein or (2) any jurisdiction from or through
which payment is made by or on behalf of the Company (including, without limitation, the jurisdiction of any Paying Agent) (each of (1) and (2), a “Tax Jurisdiction” which, for the avoidance of doubt, shall not include the
United States, any state thereof or the District of Columbia), will at any time be required to be made from any payments made under or with respect to the Notes, including, without limitation, payments of principal, redemption price, purchase price,
interest or premium, the Company will pay such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by each Holder or beneficial owner of Notes after
such withholding, deduction or imposition (including any such withholding, deduction or imposition from such Additional Amounts) will equal the respective amounts that would have been received in respect of such payments in the absence of such
withholding or deduction; provided, however, that no Additional Amounts will be payable with respect to: 
 (1) any Taxes to the extent such Taxes would not have been imposed but for the Holder or the beneficial owner of the Notes being a citizen or resident or national of, or incorporated in, the relevant Tax
Jurisdiction in which such Taxes are imposed or having any other present or former connection with the relevant Tax Jurisdiction other than the mere acquisition, holding, exercise or enforcement of rights, or receipt of payment in respect of the
Notes; 
 (2) any Taxes to the extent such Taxes are imposed or withheld as a result of the failure of the
Holder of the Note or beneficial owner of the Notes to comply, to the extent such Holder is legally entitled, with any reasonable written request, made by the Company or any Guarantor to that Holder or beneficial owner in writing at least 90 days
before any such withholding or deduction would be payable, to provide information concerning the nationality, residence or identity of such Holder or beneficial owner or to make any valid and timely declaration or similar claim or satisfy any
certification information or other reporting requirement, which is required or imposed by a statute, treaty, regulation or administrative practice of the relevant Tax Jurisdiction as a precondition to any exemption from or reduction in all or part
of such Taxes; 
 (3) any Taxes to the extent such Taxes were imposed as a result of the presentation of a Note
for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been
presented on the last day of such 30 day period); 
 (4) any estate, inheritance, gift, sale, personal property
or similar Taxes; 

  
 66 

 (5) any Taxes payable other than by deduction or withholding from payments
under, or with respect to, the Notes; or 
 (6) any combination of items (1) through (5) above.

 For purposes of this Section 5.16, “Taxes” means any present or future tax, duty, assessment, or other
governmental charge of whatever nature imposed, levied, collected, withheld or assessed, including any penalties and interest related thereto. 
 The Company also will not pay any Additional Amounts to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of the Note to the extent that a beneficiary or settlor with
respect to such fiduciary, or a member of such partnership or a beneficial owner thereof, would not have been entitled to the payment of such Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of the Note.

 (b) In addition to Section 5.16(a) above, if the Company is succeeded by an entity organized or existing in a Permitted
Foreign Jurisdiction as permitted by Section 6.01, the Company or a Guarantor, as applicable, will also pay and indemnify the Holder for any present or future stamp, issue, registration, value added, court or documentary Taxes, or any other
excise or property taxes, charges or similar levies (including penalties, interest and any other reasonable expenses related thereto) or Taxes which are levied by any Tax Jurisdiction on the execution, delivery, registration or enforcement of any of
the Notes, the Indenture, any Subsidiary Guarantee, or any other document or instrument referred to therein or the receipt of payments with respect thereto. 
 (c) If the Company or any Guarantor becomes obligated to pay Additional Amounts with respect to any payment under or with respect to the Notes or any Subsidiary Guarantee, the Company or any Guarantor, as
applicable, will deliver to the Trustee on a date that is at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment date, in which case the Company will notify
the Trustee promptly after such obligation arises (and in any event within five Business Days thereof)) an Officers’ Certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The
Officers’ Certificate must also set forth any other information reasonably necessary to enable the paying agents to pay Additional Amounts to Holders on the relevant payment date. The Trustee shall be entitled to rely solely on such
Officers’ Certificate as conclusive proof that such payments are necessary. The Company or any Guarantor, as applicable, will provide the Trustee with documentation reasonably satisfactory to the Trustee evidencing the payment of Additional
Amounts. 
 (d) The Company or any Guarantor, as applicable, will make all withholdings and deductions required by law and will
remit the full amount deducted or withheld to the relevant Tax authority in accordance with applicable law. Upon request, the Company or any Guarantor, as applicable, will provide to the Trustee an official receipt or, if official receipts are not
obtainable, other documentation reasonably satisfactory to the Trustee evidencing the payment of any Taxes so deducted or withheld and will attach to each official receipt or other documentation an Officers’ Certificate stating the amount of
such Taxes paid per $1,000 principal amount of the Notes then outstanding. Upon request, copies of those official receipts or other documentation, as the case may be, will be made available by the Trustee to the Holders of the Notes. 

  
 67 

 (e) The Company and the Guarantors, jointly and severally, will reimburse the Holders of
the Notes, upon written request of such Holder of Notes and appropriate proof of payment for the amount of (i) any Taxes levied or imposed by a Tax Jurisdiction and payable by such Holder or the applicable beneficial owner in connection with
payments made under or with respect to the Notes held by such Holder or any Note guarantee; and (ii) any Taxes levied or imposed with respect to any reimbursement under the foregoing clause (i) or this clause (ii), so that the net amount
received by the applicable beneficial owner after such reimbursement will not be less than the net amount such beneficial owner would have received if the Taxes giving rise to the reimbursement described in clauses (i) and/or (ii) had not
been imposed, provided, however, that the indemnification obligation provided for in this paragraph (e) shall not extend to Taxes imposed for which the Holder or beneficial owner of the Notes would not have been eligible to
receive payment of Additional Amounts hereunder by virtue of clauses (1) through (5) in paragraph (a) above or to the extent such Holder or beneficial owner received Additional Amounts with respect to such payments. 

(f) Whenever in the Indenture or the Notes, there is mentioned, in any context, the payment of amounts based upon the principal amount
of the Notes or of principal, interest or of any other amount payable under, or with respect to, any of the Notes, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof. 
 (g) The obligations of the Company and the Guarantors under this
Section 5.16 will survive termination, defeasance or discharge of the Indenture, any transfer by a Holder or beneficial owner of its Notes and will apply mutatis mutandis to any jurisdiction in which any successor person to the Company
or any Guarantor is incorporated, engaged in business or resident for tax purposes or any jurisdiction from or through which such person makes any payment on the Notes (or any Subsidiary Guarantee) and any department or political subdivision thereof
or therein. 
 SECTION 5.17 No Inducements. 
 The Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or
as an inducement to any consent, waiver or amendment of any terms or provisions of the Indenture or the Notes, unless such consideration is offered to be paid or agreed to be paid to all Holders which so consent, waive or agree to amend in the time
frame set forth in solicitation documents relating to such consent, waiver or agreement. 

  
 68 

 SECTION 5.18 Changes in Covenants Upon an Investment Grade Rating Event. 

If an Investment Grade Rating Event occurs and no Default or Event of Default has occurred and is continuing under the Indenture, then
upon delivery to the Trustee of an Officers’ Certificate to the foregoing effect, 
 (a) each of the covenants contained
in the following Sections will cease to apply to the Company and its Restricted Subsidiaries: 
 (1)
Section 5.07 (Limitation on Restricted Payments); 
 (2) Section 5.08 (Limitation on Dividends and
Other Payment Restrictions Affecting Subsidiaries); 
 (3) Section 5.09 (Limitation on Incurrence of
Indebtedness and Issuance of Preferred Stock); 
 (4) Section 5.10 (Limitation on Asset Sales); 

(5) Section 5.11 (Limitation on Transactions with Affiliates); 

(6) Section 5.12 (Limitation on Liens); 

(7) Section 5.13 (Additional Subsidiary Guarantees); 

(8) clause (4) of Section 6.01(a) (Limitation on Mergers, Consolidations and Sales of Assets); and 

(b) the following covenants will apply to the Company and its Restricted Subsidiaries: 

(1) Restrictions on Secured Indebtedness. If the Company or any Restricted Subsidiary incurs any Indebtedness
secured by a Lien (other than a Permitted Lien) on any asset or property of the Company or any Restricted Subsidiary, the Company or such Restricted Subsidiary will secure the Notes equally and ratably with (or at the Company’s option, prior
to) such secured Indebtedness so long as such Indebtedness is so secured, unless the aggregate amount of all Indebtedness secured by Liens (other than Permitted Liens), together with all Attributable Indebtedness of the Company and the Restricted
Subsidiaries with respect to any Sale/Leaseback Transactions (with the exception of such transactions which are excluded as set forth in subclauses (A) through (D) of clause (2) below), would not exceed 12.5% of Consolidated Net
Tangible Assets. 
 (2) Restrictions on Sale/Leaseback Transactions. The Company will not, and will not
permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction, unless the aggregate amount of all Attributable Indebtedness with respect to such transaction plus all secured Indebtedness of the Company and the Restricted Securities
(with the exception of Indebtedness secured by Permitted Liens) would not exceed 12.5% of Consolidated Net Tangible Assets outstanding at any time. The restriction in the preceding sentence shall not apply to, and there shall be excluded from
Attributable Debt in any computation under such restriction, any Sale/Leaseback Transaction if: 
 (A) the lease
is for a period, including renewal rights, not in excess of three years; 

  
 69 

 (B) the sale of the asset or property subject to the Sale/Leaseback
Transaction is made within 270 days after its acquisition, construction or improvements; 
 (C) the transaction
is between the Company and a Restricted Subsidiary or between Restricted Subsidiaries; or 
 (D) the Company,
within 270 days after the sale is completed, applies to the retirement of its Indebtedness or that of a Restricted Subsidiary, or to the purchase of other assets or properties which will constitute Productive Assets, an amount not less than the
greater of: 
  

	 	(i)	the net proceeds of the sale of the asset or property leased; and 

  

	 	(ii)	the fair market value (as determined by the Company in good faith) of the asset or property leased; 

provided, however, that the amount to be applied to the retirement of Indebtedness or the purchase of other
assets or properties shall be reduced by: (x) the principal amount of any of the Company’s debentures or notes (including the Notes) or those of a Restricted Subsidiary surrendered within 270 days after such sale to the applicable trustee
for retirement and cancellation; (y) the principal amount of Indebtedness, other than the items referred to in the preceding clause (x), voluntarily retired by the Company or a Restricted Subsidiary within 270 days after such sale; and
(z) associated transaction and other related expenses.

ARTICLE VII 

DEFAULTS AND REMEDIES 
 SECTION
7.01 Events of Default. 
 Each of the following constitutes an “Event of Default” with respect to the
Notes: 
 (1) a default in the payment when due of interest or Additional Amounts, if any, with respect to the
Notes and such default continues for a period of 30 days; 

  
 72 

 (2) a default in the payment of the principal of or premium, if any, on the
Notes when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; 
 (3) the failure by the Company for 30 days after notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding to comply with any of its obligations under
Section 5.10 or Section 5.15 (other than a failure to repurchase Notes when due), or failure by the Company to comply with its obligations described under Section 6.01; 

(4) the failure by the Company or any of its Restricted Subsidiaries for 60 days after notice from the Trustee or the
Holders of at least 25% in principal amount of the Notes then outstanding to comply with any of its other agreements in the Indenture, the Notes or any Subsidiary Guarantee (provided that, with respect to Section 5.03, the Company shall
have not less than 120 days from the failure to comply with such Section to cure such failure); 
 (5) a default
occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee exists on or is created after the Initial Issuance Date, which default: 

(A) is caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any
grace period provided in such Indebtedness, including any extension thereof (a “Payment Default”); or 
 (B) results in the acceleration of such Indebtedness prior to its Stated Maturity, 

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under
which there has been a Payment Default or the maturity of which has been so accelerated, aggregates in excess of $50.0 million; provided that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid,
within a period of 45 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Notes shall be
automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
 (6) the
failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (to the extent not covered by insurance by a reputable and creditworthy
insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 consecutive days; 

  
 73 

 (7) the repudiation by any Guarantor of its obligations under its
Subsidiary Guarantee or any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable against a Guarantor for any reason, except, in each case, by reason of the release of such Guarantor in accordance with the Indenture; and

 (8) the Company, any Guarantor, or any Significant Subsidiary, pursuant to or within the meaning of any
Bankruptcy Law: 
 (A) commences a voluntary case; 

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

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

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

(E) admits in writing it generally is not paying its debts as they become due. 

(9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in
effect for 90 days and that: 
 (A) is for relief against the Company, any Guarantor or any Significant
Subsidiary, as debtor in an involuntary case; 
 (B) appoints a Bankruptcy Custodian of the Company, any
Guarantor or any Significant Subsidiary, or a Bankruptcy Custodian for all or substantially all of the property of the Company, any Guarantor or any Significant Subsidiary, or 

(C) orders the liquidation of the Company, any Guarantor or any Significant Subsidiary. 

SECTION 7.02 Acceleration. 
 If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable
immediately. Notwithstanding the preceding sentence, in the case of an Event of Default arising from clause (8) or (9) of Section 7.01, all outstanding Notes will become due and payable without further action or notice. The Holders of
a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default (except with respect to nonpayment of principal, interest, premium or Additional Amounts that have become due solely because of the acceleration) have been cured or waived. 

  
 74 

 SECTION 7.03 Other Remedies. 

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of,
premium, if any, or interest and Additional Amounts, if any, on the Notes or to enforce the performance of any provision of the Notes or the 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 7.04 Waiver of Defaults. 
 Subject to Sections 7.07 and 10.02, the Holders of a majority in principal amount of Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing
Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or interest, premium, or Additional Amounts, if any, on the Notes. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 
 SECTION 7.05 Control by Majority. 
 The Holders of a majority in principal amount of the then outstanding Notes will have the right to direct in writing the time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it; provided, however that the Trustee may refuse to follow any direction that conflicts with applicable law or the Indenture, that the Trustee determines may be
unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

 SECTION 7.06 Limitations on Suits. 
 Subject to Section 7.07 hereof, a Holder may pursue a remedy with respect to the Indenture or the Notes or any related Subsidiary Guarantees only if: 

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

(2) the 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; 
 (3) such Holder or Holders offer and, if requested, provide to the Trustee
indemnity satisfactory to the Trustee against any loss, liability or expense; 

  
 75 

 (4) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer of indemnity; and 
 (5) during such 60-day period the Holders of a
majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 
 A Holder may not use the Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 
 SECTION 7.07 Rights of Holders to Receive Payment. 
 Notwithstanding any
other provision of the Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, interest and Additional Amounts, if any, on, the Notes (including in connection with an Asset Sale Offer or a Change of Control
Offer), on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent
of the Holder. 
 SECTION 7.08 Collection Suit by Trustee. 
 If an Event of Default specified in clause (1) or (2) of Section 7.01 hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an
express trust against the Company or a Guarantor for the whole amount of principal, premium, interest and Additional Amounts, if any, remaining unpaid on the Notes, and interest on overdue principal and premium, if any, and, to the extent lawful,
interest on overdue interest, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 SECTION 7.09 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 Company or a Guarantor or their respective creditors or properties and shall be entitled
and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Bankruptcy 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 8.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 8.07 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 of the Notes may be entitled to 

  
 76 

 
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 thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding. 
 SECTION 7.10 Priorities. 
 If the Trustee collects any money pursuant to this Article VII, it shall pay out the money in the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 8.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by
the Trustee and the Trustee’s costs and expenses of collection; 
 Second: to Holders for amounts due
and unpaid on the Notes for principal, premium, if any, interest, if any, and any Additional Amounts, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any,
interest, if any, and any Additional Amounts, if any, respectively; and 
 Third: to the Company or the
Guarantors or to such party as a court of competent jurisdiction shall direct. 
 The Trustee, upon prior written notice to the
Company, may fix record dates and payment dates for any payment to Holders pursuant to this Section 7.10. 
 SECTION 7.11 Undertaking
for Costs. 
 In any suit for the enforcement of any right or remedy under the Indenture or in any suit against the Trustee
for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 7.11 does not apply to a suit by the Trustee, a
suit by a Holder pursuant to Section 7.07, or a suit by a Holder or Holders of more than 10% in aggregate principal amount of the then outstanding Notes. 
 ARTICLE VIII 
 TRUSTEE 
 SECTION 8.01 Duties of Trustee. 
 (a) If an Event of Default has occurred
and is continuing, the Trustee shall exercise such of the rights and powers vested in it by the Indenture, and use the same degree of care and skill in such exercise, as a prudent person would exercise or use under the circumstances in the conduct
of such person’s own affairs. 

  
 77 

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

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

(2) in the absence of bad faith on its part, 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 the Indenture. However, the Trustee shall examine such certificates and opinions to determine whether, on
their face, they appear to conform to the requirements of the Indenture. 
 (c) The Trustee may not be relieved from
liabilities for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (1) this paragraph does not limit the effect of Section 8.01(b); 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

 (3) 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 7.05. 
 (d) Whether or not therein expressly so provided,
every provision of the Indenture that in any way relates to the Trustee is subject to the provisions of this Section 8.01. 
 (e) No provision of the Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights or powers under
the Indenture at the request or direction of any Holder of Notes, unless such Holder has offered to the Trustee security or indemnity satisfactory to it against any loss, liability, cots or expense that might be incurred by it in compliance with
such request or direction. 
 (f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company and the Guarantors. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. All money received by the Trustee shall, until applied as herein
provided, be held in trust for the payment of the principal of, premium, if any, interest, if any, and Additional Amounts, if any, on, the Notes. 

  
 78 

 SECTION 8.02 Rights of Trustee. 

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains
from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both to be provided. 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. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by
it hereunder in good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and shall not
be responsible for the misconduct or negligence of any agent appointed 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 its rights or powers conferred upon it by this Indenture. 
 (e) Unless otherwise specifically provided in the Indenture, any demand, request, direction or notice from the Company or any Guarantor shall be sufficient if signed by an Officer of the Company.

 (f) The Trustee shall not be deemed to know or have notice of any Default or Event of Default unless a Responsible Officer
of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and
this Supplemental Indenture. When a Default is cured, it ceases. 
 (g) The permissive rights of the Trustee enumerated herein
shall not be construed as duties. 
 SECTION 8.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company,
any Guarantor or any of their respective Affiliates with the same rights it would have if it were not the Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) after a Default has occurred and is
continuing, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is subject to Sections 8.10 and 8.11. 

SECTION 8.04 Trustee’s Disclaimer. 
 The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of the Indenture or the Notes, it shall not be accountable for the Company’s

  
 79 

 
use of the proceeds from the Notes or any money paid to the Company or any Guarantor or upon the Company’s or such Guarantor’s direction under any provision hereof, it shall not be
responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other documents in connection with the
sale of the Notes or pursuant to the Indenture, other than its certificate of authentication. 
 SECTION 8.05 Notice of Defaults.

 If a Default or Event of Default occurs and is continuing and it is known to the Trustee, the Trustee shall mail to Holders
of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, any Note,
the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders. 
 SECTION 8.06 Reports by Trustee to Holders. 
 Within 60 days after each
May 15 of each year after the execution of this Supplemental Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders, the Company and the Guarantors a brief report dated as of such reporting date that
complies with TIA § 313(a); provided, however, that if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted. The Trustee also shall comply
with TIA § 313(b). The Trustee shall also transmit by mail all reports if and as required by TIA § 313(c). 

A copy of each report at the time of its mailing to the Holders shall be filed by the Trustee with the Commission and each securities
exchange, if any, on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any securities exchange. 
 SECTION 8.07 Compensation and Indemnity. 
 The Company agrees to pay to
the Trustee for its acceptance of the Indenture and services hereunder such compensation as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company agrees to reimburse the Trustee upon request for all reasonable disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel. 
 The Company and the Guarantors hereby jointly and severally indemnify the Trustee against
any and all loss, liability, damage, claim or expense, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred by it arising out of or in connection with the acceptance or administration of its
duties under the Indenture, including the costs and expenses of enforcing the Indenture against the Company (including this Section 8.07) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or
any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except as set forth in the next 

  
 80 

 
following paragraph. The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company or the Guarantors of their obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses
of such counsel. The Company need not pay for any settlement made without its consent. 
 The Company shall not be obligated to
reimburse the Trustee for any expense or indemnify against any loss or liability incurred by the Trustee to the extent such expense, loss or liability is attributable to the Trustee’s negligence, bad faith or willful misconduct. 

To secure the payment obligations of the Company in this Section 8.07, 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 of, or premium, if any, interest, if any, or Additional Amounts, if any, on particular Notes. Such Lien and the Company’s obligations under this
Section 8.07 shall survive the satisfaction and discharge of the Indenture. 
 When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 7.01(8) or (9) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law. 
 The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent
applicable. 
 SECTION 8.08 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 8.08. 
 The Trustee may resign in writing upon 60 days notice at any time and be discharged from the trust
created hereby by so notifying the Company and the Guarantors. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee, the Company and the Guarantors. The Company may
remove the Trustee if: 
 (1) the Trustee fails to comply with Section 8.10; 

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee
under any Bankruptcy Law; 
 (3) a Bankruptcy Custodian or public officer takes charge of the Trustee or its
property; or 
 (4) the Trustee otherwise becomes incapable of acting. 

  
 81 

 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for
any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to
replace the successor Trustee appointed by the Company. 
 If a successor Trustee does not take office within 30 days after the
retiring or removed Trustee resigns or is removed, the retiring or removed Trustee, the Company, any Guarantor or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 8.10, any 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, to the Company and to the Guarantors.
Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the retiring Trustee under the 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, subject to the Lien provided for in Section 8.07. 

Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 8.08, the obligations of the Company under
Section 8.07 shall continue for the benefit of the retiring Trustee. 
 SECTION 8.09 Successor Trustee by Merger, etc. 

Subject to Section 8.10, if the Trustee consolidates, merges or converts into, or transfers all or substantially all of its
corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. 
 In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the
name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 8.10 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, any State thereof or the District of Columbia and authorized under
such laws to exercise corporate trust power, that is subject to supervision or examination by Federal or State (or the District of Columbia) authority and that has a combined capital and surplus of at least $50.0 million as set forth in its most
recent published annual report of condition. 

  
 82 

 The Indenture shall always have a Trustee who satisfies the requirements of TIA
§§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA § 310(b). 

SECTION 8.11 Preferential Collection of Claims Against the Company or a Guarantor. 

The Trustee is subject to and shall comply with the provisions of TIA § 311(a), excluding any creditor relationship listed in
TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 ARTICLE IX 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 9.01 Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may, at the option of its Board of Directors evidenced by a Board Resolution, at any time, exercise its rights under either Section 9.02 or 9.03 hereof with respect to all outstanding
Notes upon compliance with the conditions set forth below in this Article IX. 
 SECTION 9.02 Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.02, the Company and each
of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Subsidiary Guarantees) on the
date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes (including the Subsidiary Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 9.05 hereof and the other Sections of the Indenture referred to in
clauses (1) through (4) below, and to have satisfied all their other obligations under such Notes, the Subsidiary Guarantees and the Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and premium, if any, interest, if any, or Additional Amounts, if any, on, such Notes when such payments
are due solely from the trust referred to in Section 9.04 hereof; 
 (2) the Company’s and the
Guarantors’ obligations with respect to such Notes under Sections 3.04, 3.05, 3.07, 3.08, 3.11 and 5.02, hereof; 

  
 83 

 (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and the Company’s obligations in connection therewith; and 
 (4) this Section 9.02.

 Subject to compliance with this Article IX, the Company may exercise its option under this Section 9.02 notwithstanding
the prior exercise of its option under Section 9.03 hereof. 
 SECTION 9.03 Covenant Defeasance. 

Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.03, the Company and each
of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from each of their obligations under the covenants contained in Article V (other than those in Sections 5.01, 5.02, 5.06 and
5.14) and clause (4) of Section 6.01 hereof and any covenant added to the Indenture subsequent to the Initial Issuance Date pursuant to Section 10.01 hereof with respect to all outstanding Notes on and after the date the conditions
set forth in Section 9.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will 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 will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Subsidiary Guarantees, the Company and the Guarantors may omit to comply with and will 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 will not constitute a Default or an Event of Default under Section 7.01 hereof, but, except as specified above, the remainder of the Indenture and such Notes and Subsidiary Guarantees will be unaffected
thereby. In addition, upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.03, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, Sections 7.01(3), (4),
(5), (6) and (7) hereof will not constitute Events of Default. 
 SECTION 9.04 Conditions to Legal or Covenant Defeasance.

 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 9.02 or 9.03 hereof:

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

  
 84 

 (2) in the case of an election under Section 9.02 hereof, the Company
must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that: 
 (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or 
 (B) since the Initial Issuance Date, there has been a change in the applicable federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to 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 an election under Section 9.03 hereof, the Company must deliver to the Trustee an Opinion of
Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a
Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting of Liens to secure such borrowings); 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Indenture and the
agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; 

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

(7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that
all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 

  
 85 

 SECTION 9.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous
Provisions. 
 Subject to Section 9.06 hereof, all money and non-callable Government Securities (including the
proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 9.05 and Section 12.02, the “Trustee”) pursuant to Section 9.04 hereof in respect of the outstanding
Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, or Additional Amounts, if any, but such money need not be segregated from other funds except to the
extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the cash or non-callable Government Securities deposited pursuant to Section 9.04 hereof 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. 
 Notwithstanding anything in this Article IX to the contrary, the Trustee will deliver
or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 9.04 hereof which, in the opinion of a nationally recognized investment banking firm,
appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 9.04(1) hereof), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 If the Company exercises
either its Legal Defeasance or Covenant Defeasance option, each Guarantor will be released and relieved of any obligations under its related Subsidiary Guarantee and any security for the Notes (other than the trust) will be released. 

SECTION 9.06 Repayment to Company. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or premium, if any, interest, if any, or Additional Amounts, if any,
on, any Note and remaining unclaimed for two years after such principal, premium, if any, interest, if any, or Additional Amounts, if any, has become due and payable shall, subject to any applicable abandoned property laws, be paid to the Company on
its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the
Company 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 will not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

  
 86 

 SECTION 9.07 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any Dollars or non-callable Government Securities in accordance with Section 9.02
or 9.03 hereof, 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 Company’s and the Guarantors’ obligations under the
Indenture and the Notes and the Subsidiary Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 9.02 or 9.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money
or non-callable Government Securities in accordance with Section 9.02 or 9.03 hereof, as the case may be; provided, however, that, if the Company or any Guarantor makes any payment of principal of, or premium, if any, interest, if
any, or Additional Amounts, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as applicable, will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or
non-callable Government Securities held by the Trustee or Paying Agent. 
 ARTICLE X 

SUPPLEMENTAL INDENTURES AND AMENDMENTS 
 SECTION 10.01 Without Consent of Holders.

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

(2) to provide for uncertificated Notes in addition to or in place of Certificated Notes; 

(3) to provide for the assumption of the Company’s obligations to the Holders in the case of a merger or
consolidation or sale of all or substantially all of the Company’s properties or assets;

change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under the Indenture of any such Holder; 

(5) to secure the Notes pursuant to the requirements of Section 5.12; 

(6) to add any additional Guarantor or to release any Guarantor from its Subsidiary Guarantee, in each case as provided
in the Indenture;

 (7) to comply with requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the TIA; 
 (8) to conform the text of the Indenture, the
Notes or the Subsidiary Guarantees to any provision of the “Description of the Notes” section of the Company’s Prospectus Supplement dated September 27, 2012, as filed with the Commission on October 1, 2012, relating to the
initial offering of the Notes, to the extent that such provision in such “Description of the Notes” was intended to be a substantially verbatim recitation of a provision of the Indenture, the Notes or the Subsidiary Guarantees, which
intent may be evidenced by an Officers’ Certificate to that effect; 
 (9) to provide for the issuance of
Additional Notes in accordance with the limitations set forth in the Indenture; or

Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
 SECTION 10.02 With Consent of Holders. 
 Except as provided below in this
Section 10.02, the Company, the Guarantors and the Trustee may amend or supplement the Indenture and the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including
consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 7.04 and 7.07 hereof, any existing Default or Event of Default or compliance with any provision of the Indenture or the

 Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to
the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 10.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or
supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter
into such amended or supplemental indenture. 

  
 88 

 It shall not be necessary for the consent of the Holders under this Section 10.02 to
approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. A consent to any amendment or waiver under the Indenture by any
Holder given in connection with a purchase, tender or exchange of such Holder’s Notes will not be rendered invalid by such purchase, tender or exchange. 
 After an amendment, supplement or waiver under this Section 10.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. 

The right of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation
of the Company or any Guarantor to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of the Notes as of a date identified by the Company or such
Guarantor in a notice furnished to the Holders in accordance with the terms of the Indenture. 
 However, without the consent
of each Holder affected, an amendment, supplement or waiver under this Section 10.02 may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption or repurchase of the Notes (other than the provisions of Section 5.10 or
5.15); 
 (3) reduce the rate of or change the time for payment of interest on any Note; 

(4) waive a Default or Event of Default in the payment of principal of, or premium, interest or Additional Amounts, if
any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 

(5) make any Note payable in money other than that stated in the Notes; 

(6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or premium, interest or Additional Amounts, if any, on the Notes (except as permitted in clause (7) hereof); 

  
 89 

 (7) waive a redemption or repurchase payment with respect to any Note
(other than a payment required by Section 5.10 or 5.15); 
 (8) make any change in the ranking of the Notes
or the Subsidiary Guarantees relative to other Indebtedness of the Company or the Guarantors, respectively, in either case in a manner adverse to the Holders; 
 (9) modify the Subsidiary Guarantees in any manner materially adverse to the Holders or release any Guarantor from any of its obligations under its Subsidiary Guarantee or the Indenture, except in
accordance with the terms of the Indenture; or 
 (10) make any change in the preceding amendment, supplement
and waiver provisions. 
 SECTION 10.03 Compliance with Trust Indenture Act. 

Every amendment or supplement to the Indenture or the Notes shall comply in form and substance with the TIA as then in effect.

 SECTION 10.04 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the
same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to his or her Note or portion of a Note if the Trustee receives written
notice of revocation before a date and time therefor identified by the Company or any Guarantor in a notice furnished to such Holder in accordance with the terms of the Indenture or, if no such date and time shall be identified, the date the
amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 
 The Company or any Guarantor may, but shall not be obligated to, fix a record date (which need not comply with TIA § 316(c)) for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver or to take any other action under the Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall
be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of Securities required hereunder for such amendment, supplement or waiver to be effective shall have also been given and not
revoked within such 90-day period. 

  
 90 

 After an amendment, supplement or waiver becomes effective, it shall bind every Holder,
unless it is of the type described in any of clauses (1) through (10) of Section 10.02 hereof. In such case, the amendment, supplement or waiver shall bind only each Holder who has consented to it and every subsequent Holder that
evidences the same debt as the consenting Holder’s Note. 
 SECTION 10.05 Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company
in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 
 SECTION 10.06 Trustee to Sign Amendments, etc. 
 The Trustee shall sign
any amendment or supplement authorized pursuant to this Article X if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing
or refusing to sign such amendment or supplement, the Trustee shall be entitled to receive, and, shall be fully protected in relying upon in good faith, an Officers’ Certificate and an Opinion of Counsel provided at the expense of the Company
or a Guarantor as conclusive evidence that such amendment or supplement is authorized or permitted by the Indenture. 
 SECTION 10.07 Effect
of Supplemental Indentures. 
 Upon the execution of any supplemental indenture under this Article X, the Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 

  
 91 

 ARTICLE XI 
 SUBSIDIARY GUARANTEES 
 SECTION 11.01 Subsidiary Guarantee. For value received, each
Guarantor hereby jointly and severally fully, unconditionally and absolutely guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee the due and punctual payment of the principal of, and premium, if any,
interest, if any, and Additional Amounts, if any, on the Notes and all other amounts due and payable under the Indenture and the Notes by the Company, when and as such principal, premium, interest and Additional Amounts, if any, shall become due and
payable, subject to any applicable grace period, whether at maturity or by declaration of acceleration, call for redemption or otherwise, according to the terms of the Notes and the Indenture and, in the case of any extension of time of payment or
renewal of any Notes, when the same shall become due and payable in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at maturity or by declaration or acceleration, call for redemption or
otherwise, in each case, subject to the limitations set forth in Section 11.02. 
 (b) Failing payment when due of any
amount guaranteed pursuant to the related Subsidiary Guarantee, for whatever reason, each of the Guarantors will be jointly and severally obligated to pay the same immediately. Each of the Subsidiary Guarantees hereunder is intended to be a general,
unsecured, senior obligation of the related Guarantor and will rank pari passu in right of payment with all Indebtedness of such Guarantor that is not, by its terms, expressly subordinated in right of payment to such Subsidiary Guarantee. Each of
the Guarantors hereby agrees that its obligations hereunder shall be full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Notes, its Subsidiary Guarantee, the Subsidiary Guarantee of any other Guarantor
or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company or any Guarantor, or any action to enforce the
same or any other circumstances (other than payment) which might otherwise constitute a legal or equitable discharge or defense of the Guarantors. Each of the Guarantors hereby agrees that in the event of a default in payment of the principal of, or
premium, if any, or interest on the Notes, whether at maturity or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to Section 7.06, by the
Holders, on the terms and conditions set forth in the Indenture, directly against such Guarantor to enforce such Subsidiary Guarantee without first proceeding against the Company or any other Guarantor. 

(c) The obligations of each of the Guarantors under this Article XI shall be as aforesaid full, unconditional and absolute and shall not
be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of
the obligations and liabilities of the Company or any of the Guarantors contained in the Notes or the Indenture, (ii) any impairment, modification, release or limitation of the liability of the Company, any of the Guarantors or any of their
estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the decision of any court, (iii) the
assertion or exercise by the Company, any of the Guarantors or the Trustee of any rights or remedies under the Notes or the Indenture or their delay in or failure to assert or exercise any 

  
 92 

 
such rights or remedies, (iv) the assignment or the purported assignment of any property as security for the Notes, including all or any part of the rights of the Company or any of the
Guarantors under the Indenture, (v) the extension of the time for payment by the Company or any of the Guarantors of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of the Notes or the
Indenture or of the time for performance by the Company or any of the Guarantors of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment
(whether material or otherwise) of any duty, agreement or obligation of the Company or any of the Guarantors set forth in the Indenture, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or
substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting,
the Company or any of the Guarantors or any of their respective assets, or the disaffirmance of the Notes, the Subsidiary Guarantees or the Indenture in any such proceeding, (viii) the release or discharge of the Company or any of the
Guarantors from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (ix) the unenforceability of the Notes, the related Subsidiary Guarantees or the Indenture or
(x) any other circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the related Subsidiary Guarantees) which might otherwise constitute a legal or equitable discharge of a surety or guarantor. 

(d) Each of the Guarantors hereby (i) waives diligence, presentment, demand of payment, filing of claims with a court in the event
of the merger, insolvency or bankruptcy of the Company or any of the Guarantors, and all demands whatsoever and (ii) covenants that its Subsidiary Guarantee will not be discharged except by complete performance of such Subsidiary Guarantee.
Each of the Guarantors further agrees that if at any time all or any part of any payment theretofore applied by any Person to its Guarantee is, or must be, rescinded or returned for any reason whatsoever, including, without limitation, the
insolvency, bankruptcy or reorganization of the Company or any of the Guarantors, such Subsidiary Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such
application, and such Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made. 
 (e) Each of the Guarantors shall be subrogated to all rights of the Holders and the Trustee against the Company in respect of any amounts paid by such Guarantor pursuant to the provisions of the
Indenture; provided, however, that such Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until all of the Notes and the related Subsidiary Guarantees shall
have been paid in full or discharged. 
 SECTION 11.02 Guarantors May Consolidate, etc. on Certain Terms. 

No Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person (other
than the Company or another Guarantor), whether or not affiliated with such Guarantor, unless: 
 (1) the Person
formed by or surviving any such consolidation or merger (if other than such Guarantor) shall execute a supplement to the Indenture providing for a Subsidiary Guarantee and deliver an Opinion of Counsel in accordance with the terms of the Indenture;
and 
 (2) immediately after giving effect to such transaction, no Default or Event of Default exists.

  
 93 

 Upon any such consolidation or merger of a Guarantor and upon the execution by the
successor Person of a supplemental indenture, executed by the Trustee, providing for a Subsidiary Guarantee, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a
Guarantor. 
 SECTION 11.03 Limitation on Liability of the Guarantors. Each Guarantor and by its acceptance hereof each Holder hereby
confirms that it is the intention of all such parties that the guarantee by such Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state law. To effectuate the foregoing
intention, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Subsidiary Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed
liabilities of such Guarantor and to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee, result in the obligations of such Guarantor under
its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. 
 SECTION 11.04 Release
of Guarantors from Subsidiary Guarantee. 
 Notwithstanding any other provisions of the Indenture, each Guarantor will be
automatically and unconditionally released and relieved of any obligations under its Subsidiary Guarantee, and no further action by such Guarantor, the Company or the Trustee is required for the release of such Guarantor’s Subsidiary Guarantee:

 (1) upon a sale or other disposition (including by way of merger or consolidation) of all or substantially
all of the assets of such Guarantor or all of the Capital Stock of such Guarantor owned by the Company or its Subsidiaries to a Person other than the Company or a Restricted Subsidiary; provided, however, that the Net Proceeds of such
sale or disposition are applied in accordance with Sections 4.10 and 5.10; 
 (2) upon Legal Defeasance or
Covenant Defeasance in accordance with Article IX, or upon satisfaction and discharge of the Indenture in accordance with Article XII; 
 (3) upon the Board of Directors designating such Guarantor as an Unrestricted Subsidiary; provided, however, that such designation is conducted in accordance with the Indenture; or

 (4) provided that no Default or Event of Default shall have occurred and shall be continuing, (i) upon
the liquidation or dissolution of such Guarantor or (ii) at such time as such Guarantor ceases both (x) to be a Significant U.S. Subsidiary and (y) to be an obligor with respect to any Indebtedness the incurrence of which resulted in
or would result in the obligation of such Guarantor to guarantee the Notes under the Indenture. 

  
 94 

 The Trustee shall deliver an appropriate instrument evidencing any release of a Guarantor
from its Subsidiary Guarantee upon receipt of a written request of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel that the Guarantor is entitled to such release in accordance with the provisions of the Indenture.
If the Guarantor is not so released it shall remain liable for the full amount of principal of, and premium, if any, interest, if any, and Additional Amounts, if any, on the Notes, subject to the limitations of Section 11.03. 

SECTION 11.05 Contribution. In order to provide for just and equitable contribution among the Guarantors, the Guarantors hereby agree, inter se,
that in the event any payment or distribution is made by any Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Guarantor (as applicable) in a
pro rata amount based on the net assets of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Notes or any
other Guarantor’s obligations with respect to its Subsidiary Guarantee of the Notes. 
 SECTION 11.06 Execution and Delivery of
Guaranty. The execution by each Guarantor of this Supplemental Indenture (or a further supplemental indenture) evidences the Subsidiary Guaranty of such Guarantor, whether or not the person signing as an officer of the Guarantor still holds that
office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Subsidiary Guaranty set forth in this Indenture on behalf of each Guarantor. 

ARTICLE XII 

SATISFACTION AND DISCHARGE 

SECTION 12.01 Satisfaction and Discharge. 
 (a) The Indenture shall cease to be of further effect with respect to the Notes (except that the Company’s obligations under Section 8.07, the Trustee’s and Paying Agent’s obligations
under Section 9.06 and the rights, powers, protections and privileges accorded the Trustee under Article VIII shall survive), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging the satisfaction and
discharge of this Indenture with respect to the Notes, when: 
 (1) either: 

(A) all outstanding Notes theretofore authenticated and issued (other than destroyed, lost or stolen Notes that have been
replaced or paid) have been delivered to the Trustee for cancellation; or 

  
 95 

 (B) all outstanding Notes not theretofore delivered to the Trustee for
cancellation: 
  

	 	(i)	have become due and payable, or 

  

	 	(ii)	will become due and payable at their Stated Maturity within one year, or 

  

	 	(iii)	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 Company, 

 and, in the case of clause (i), (ii) or (iii) above, the Company or a
Guarantor has irrevocably deposited or caused to be deposited with the Trustee as funds (immediately available to the Holders in the case of clause (i)) in trust for such purpose cash in Dollars, non-callable Government Securities, or a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants, to pay and discharge the entire Indebtedness on the Notes for principal and
interest to the date of such deposit (in the case of Notes which have become due and payable) or for principal, premium, if any, interest, if any, and Additional Amounts, if any, to the stated date for payment thereof or on the applicable redemption
date, as the case may be; 
 (2) the Company or a Guarantor has paid or caused to be paid all other sums payable
by them hereunder with respect to the Notes; and 
 (3) the Company has delivered to the Trustee an
Officers’ Certificate stating that all conditions precedent to satisfaction and discharge of the Indenture with respect to the Notes have been complied with, together with an Opinion of Counsel to the same effect. 

SECTION 12.02 Application of Trust Money. 
 Subject to Section 9.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 12.01 hereof will be held in
trust and applied by the Trustee, in accordance with the provisions of the Notes and the Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to
the Persons entitled thereto, of the principal, premium, if any, interest, if any, and Additional Amounts, if any, for whose payment such money has been deposited with the Trustee, but such money need not be segregated from other funds except to the
extent required by law. 
 Notwithstanding anything in this Article XII to the contrary, the Trustee will deliver or pay to the
Company from time to time upon the request of the Company any money or non-callable Government Securities s held by it as provided in Section 12.01 which are in excess of the amount thereof that would then be required to be deposited to effect
the satisfaction and discharge of the Indenture pursuant to Section 12.01. 

  
 96 

 SECTION 12.03 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any Dollars or non-callable Government Securities in accordance with
Section 12.01 hereof by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under the Indenture
and the Notes and the Subsidiary Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money or non-callable
Government Securities in accordance with Section 12.01 hereof, as the case may be; provided, however, that, if the Company or any Guarantor makes any payment of principal of, premium, if any, interest, if any, or Additional
Amounts, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as applicable, will be subrogated to the rights of the Holders to receive such payment from the money or non-callable Government Securities
held by the Trustee or Paying Agent.

 [FORM OF REVERSE SIDE OF NOTE] 

6 1/4% Senior Note due 2022 

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless
otherwise indicated. 
 1. Interest. Bristow Group Inc., a Delaware corporation (the
“Company”), promises to pay interest on the principal amount of this Note at 6 1/4% per annum from October 12, 2012 until maturity. The Company will pay interest and semi-annually in arrears on
April 15 and October 15 of each year, commencing April 15, 2013, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). In certain circumstances specified in
the Indenture, the Company may be required to pay Additional Amounts with respect to the Notes. Whenever in this Note there is mentioned, in any context, the payment of amounts based upon the principal amount of this Note or of principal, interest
or of any other amount payable under, or with respect to, this Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in
respect thereof. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of
Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except
in the case of the original issuance of Notes, in which case interest shall accrue from the date of authentication. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium, if any, at a rate equal to the then applicable interest rate on the Notes to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if
any, and Additional Amounts, if any, (without regard to any applicable grace period) at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered
Holders of Notes at the close of business on the April 1 or October 1 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in
Section 3.13 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, interest and Additional Amounts, if any, at the corporate trust office or agency of the Trustee within the City and
State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds
will be required with respect to principal of and interest, premium and Additional Amounts on all Global Notes and all other Notes the Holders of which hold at least $10 million principal amount of Notes and shall have provided wire transfer
instructions to the Company or the Paying Agent. 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. 

  
 A-3

 3. Paying Agent and Registrar. Initially, the corporate trust office or agency of
U.S. Bank National Association, the Trustee under the Indenture, in New York, New York will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Restricted
Subsidiaries may act as Paying Agent or Registrar. 
 4. Indenture. The Company issued the Notes under the Third
Supplemental Indenture, dated as of October 12, 2012 (the “Supplemental Indenture”), among the Company, the Guarantors party thereto and U.S. Bank National Association, as Trustee (herein called the “Trustee”,
which term includes any successor trustee under the Indenture), to the Indenture, dated as of June 17, 2008 (as amended and supplemented by the Supplemental Indenture, and as further amended and supplemented from time to time, in each case,
with respect to the Notes, the “Indenture”) among the Company, the Guarantors party thereto and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA.
The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. In the event of a conflict between this Note and the Indenture, the Indenture shall govern. The Notes are senior unsecured
obligations of the Company limited to $450.0 million aggregate principal amount in the case of Notes issued on the Initial Issuance Date. 
 5. Optional Redemption. The Notes are redeemable as provided in Section 4.08 of the Indenture. 
 6. Mandatory Redemption. Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or repurchase
the Notes at the option of the Holder. 
 7 Repurchase at Option of Holder. 

(a) If a Change of Control Trigger Event occurs, the Company will be required to make an offer (a “Change of Control
Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at an offer price in cash equal to 101% of the aggregate principal amount, plus accrued and unpaid
interest and Additional Amounts, if any, to the date of repurchase (the “Change of Control Payment”). Within 30 days following a Change of Control Trigger Event, the Company will mail a notice to each Holder and the Trustee
describing the transaction that constitutes the Change of Control Trigger Event and setting forth the procedures governing the Change of Control Offer as required by Section 5.15 of the Indenture. 

(b) On the 366th day after an Asset Sale (or, at the Company’s option, such earlier date), if the aggregate amount of Excess
Proceeds exceeds $50.0 million, the Company will be required to make an Asset Sale Offer pursuant to Section 5.10 of the Indenture to all Holders of Notes and, to the extent required by the terms of other Pari Passu Indebtedness, to all holders
of other Pari Passu Indebtedness outstanding with similar provisions requiring the Company to make an offer to purchase such Pari Passu Indebtedness with the proceeds from any Asset Sale (“Pari Passu Notes”), to purchase the maximum
principal amount of Notes and any such Pari Passu Notes to which the Asset Sale Offer applies that may be purchased out of the 

  
 A-4

 
Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes and Pari Passu Notes, plus accrued and unpaid interest and Additional Amounts, if any,
to the date of purchase, in accordance with the procedures set forth in Section 4.10 of the Indenture or the agreements governing the Pari Passu Notes, as applicable. To the extent that the aggregate principal amount of Notes tendered pursuant
to an Asset Sale Offer is less than the amount that the Company is required to repurchase, the Company may use any remaining Excess Proceeds for any purpose not prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by
Holders thereof and other Pari Passu Notes surrendered by holders or lenders, collectively, exceeds the amount that the Company is required to repurchase, the Trustee shall select the Notes and Pari Passu Notes to be purchased on a pro rata
basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Notes (except that any Notes represented by a Note in global form will be selected by such method as the Depositary or its nominee or successor may require or,
where the nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be redeemed (with such adjustments as may be
deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.
Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to
Elect Purchase” on the reverse of the Notes. 
 8. Notice of Redemption. Notice of redemption will be mailed at
least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000,
unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption. 

9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents,
and the Company may require a Holder to pay a sum sufficient to cover any transfer tax or other governmental taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion
of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

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

11. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented
with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the notes), and

  
 A-5

 
any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount
of the then outstanding Notes (including consents obtained in connection with a purchase of, tender offer or exchange offer for Notes). Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure
any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of Certificated Notes, to provide for the assumption of the Company’s obligations to Holders of Notes in the case of a merger or
consolidation or sale of all or substantially all of the Company’s properties or assets, to secure the Notes pursuant to Section 5.12 of the Indenture, to make any change that would provide any additional rights or benefits to the Holders
of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, to add any additional Guarantor
with respect to the Notes or to release any Guarantor from its Subsidiary Guarantee, in each case as provided in the Indenture, to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under
the TIA, to conform the text of the Indenture, the Notes or the Subsidiary Guarantees to any provision of “Description of the Notes” section of the Company’s Prospectus Supplement dated September 27, 2012, as filed with the
Commission on October 1, 2012, relating to the initial offering of the Notes to the extent that such provision in such “Description of the Notes” was intended to be a substantially verbatim recitation of a provision of the Indenture,
the Notes or the Subsidiary Guarantees, which intent may be evidenced by an Officers’ Certificate to that effect, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture or to evidence or
provide for the acceptance of appointment under the Indenture of a successor Trustee. 
 12. Defaults and Remedies. If
any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the preceding
sentence, in the case of an Event of Default arising from clause (8) or (9) of Section 7.01 of the Indenture, all outstanding Notes will become due and payable without further action or notice. The Holders of a majority in aggregate
principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders of the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all
existing Events of Default (except with respect to nonpayment of principal, interest, premium or Additional Amounts that have become due solely because of the acceleration) have been cured or waived. Holders of the Notes may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, interest, premium or Additional Amounts) if it determines that withholding notice
is in their interest. Except as provided in the Indenture, the Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or
Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or interest, premium or Additional Amounts, if any, on the Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance 

  
 A-6

 
with the Indenture, and the Company will be required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

 13. Defeasance and Discharge. The Notes are subject to defeasance and discharge upon the terms and conditions
specified in the Indenture. 
 14. Trustee Dealings with Company. The Trustee in its individual or any other capacity
may become the owner or pledgee of Notes and may otherwise deal with the Company, any Guarantor or any of their respective Affiliates with the same rights it would have if it were not the Trustee. 

15. No Recourse Against Others. No director, officer, employee, incorporator, member, partner or stockholder or other owner of
Capital Stock of the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 

16. Authentication. This Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose
until authenticated by the manual signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence that this Note has been authenticated under the Indenture. 

17. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in
common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

19. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused “CUSIP” numbers and corresponding “ISIN” numbers to be printed on the Notes and the Trustee may use “CUSIP” numbers in notices of redemption as a convenience to Holders. No representation is made as
to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption. Reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any
defect in or omission of such numbers. 
 20. Governing Law. THE INDENTURE, THIS NOTE AND THE SUBSIDIARY GUARANTEES
WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 21. Successor
Corporation. In the event a successor assumes all the obligations of the Company under the Notes and the Indenture, pursuant to the terms thereof, the Company will be released from all such obligations to the extent provided in the Indenture.
