W I T N E S S E T H

WHEREAS, the Company and the Trustee executed and delivered an Indenture, dated as of June 27, 2016 (the “Indenture”) providing for the issuance of 4.00% Convertible Senior Notes due 2021 (the “Notes”);

WHEREAS, the Company, together with WellCare Health Plans, Inc., a Delaware corporation (“WellCare”), Wind Merger Sub, Inc., a Delaware corporation and an indirect wholly owned subsidiary of WellCare (“Merger Sub”), entered into an Agreement and Plan of Merger, dated as of November 17, 2016, pursuant to which as of the date hereof Merger Sub will be merged with and into the Company (the “Merger”) and certain other transactions will be effected, pursuant to which the Company will survive as an indirect wholly owned subsidiary of WellCare;

WHEREAS, the Merger is a “Merger Event” under Section 14.07 of the Indenture;

WHEREAS, pursuant to Section 14.07(a) of the Indenture, if the Company is party to a Merger Event, prior to or at the effective time of such Merger Event, the Company shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) of the Indenture providing for such change in the right to convert each $1,000 principal amount of Notes into the Reference Property;

WHEREAS, pursuant to Section 10.01(g) of the Indenture, the Company may amend the Indenture without the consent of any Holders in connection with any Merger Event, to provide that the Notes are convertible into Reference Property, subject to the provisions of Section 14.02, and make such related changes to the terms of the Notes to the extent expressly required by Section 14.07; and

WHEREAS, pursuant to Section 14.07(a) of the Indenture, this First Supplemental Indenture shall provide that if the holders of the Common Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be 

2

increased by any Additional Shares pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such Merger Event; and

WHEREAS, the entry into this First Supplemental Indenture by the parties hereto is in all respects authorized by the provisions of the Indenture, and all things necessary to make this First Supplemental Indenture a valid agreement of the Company in accordance with its terms have been done.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Company and the Trustee mutually covenant and agree as follows:

		1.	Effect.  This First Supplemental Indenture shall become effective upon its execution and delivery by the parties hereto.

		2.	Conversion Right.  In accordance with Section 14.07 and subject to Section 14.03 of the Indenture, at and after the effective time of the Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the Reference Property with respect to the Merger Event, which shall be cash equal to $1,058.89 per $1,000 principal amount of Notes, and the provisions of the Indenture, as modified herein, shall continue to apply, mutatis mutandis, to the Holders’ right to convert the Notes into the Reference Property pursuant to the terms of the Indenture; provided that, in the event that a Holder elects to convert its Notes in connection with a Make-Whole Fundamental Change in accordance with Section 14.03 of the Indenture, the Company shall, under the circumstances and according to the terms described in Section 14.03 of the Indenture, increase the Conversion Rate for the Notes so surrendered for conversion by the Additional Shares.

		3.	Stock Price.  The definition of the Stock Price with respect to Common Stock in Section 14.03(c) of the Indenture is hereby deleted and replaced in its entirety with the following:

“Stock Price” means, with respect to a share of Common Stock, $10.00.

		4.	Responsibility of Trustee.  The Trustee shall not be responsible for the validity or sufficiency of this First Supplemental Indenture or as to the due execution thereof by the Company or as to recitals contained herein, all of which are made solely by the Company. The Trustee shall have no duty to determine the correctness of any provision or calculations contained in this First Supplemental Indenture.

		7.	Ratification of Indenture.  Except as expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect.

in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend and the “Schedule of Exchanges of Interests 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 Exchanges of Interests 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 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 in accordance with instructions given by the Holder thereof as required by Article 12 hereof. 
 Section 1.03
Additional Notes. 
 (a) With respect to any Additional Notes, there shall be (a) established in or pursuant to a Board
Resolution and (b) (i) set forth or determined in the manner provided in an Officers’ Certificate or (ii) established in one or more indentures supplemental to the Indenture, prior to the issuance of such Additional Notes: 

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to the Indenture; 

(2) the issue price and the issue date of such Additional Notes, including the date from which interest shall accrue and the
first interest payment date therefor; and 
 (3) if applicable, that such Additional Notes shall be issuable in whole or in
part in the form of one or more Global Notes and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be 

  
 2 

 
borne by such Global Notes in addition to or in lieu of those called for by Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Exhibit A in which
any such Global Notes may be exchanged in whole or in part for Additional Notes registered, or any transfer of such Global Notes in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Note or
a nominee thereof. 
 (b) If any of the terms of any Additional Notes are established by action taken pursuant to a Board Resolution, a copy
thereof shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or the indenture supplemental to the Indenture setting forth the terms of the Additional Notes. 

(c) The Initial Notes and any Additional Notes shall be considered collectively as a single class for all purposes of the Indenture. Holders
of the Initial Notes and any Additional Notes will vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Initial Notes or any Additional Notes shall have the right
to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent. 
 Section 1.04
Execution and Authentication. 
 The Notes shall be executed on behalf of the Company by its Chairman of the Board, President
or a Vice President of the Company (or any other officer of the Company designated in writing by or pursuant to authority of the Board of Directors and delivered to the Trustee from time to time). The signature of any of these officers on the Notes
may be manual or facsimile. 
 Notes bearing the manual or facsimile signatures of individuals who were at any time the proper officers of
the Company or such Guarantor, as the case may be, shall bind the Company or such Guarantor, as the case may be, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such
Notes or did not hold such offices at the date of such Notes. 
 A Note will not be valid until authenticated by the manual signature of the
Trustee. Such signature will be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee will, upon
receipt of a written order of the Company signed by an officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The Trustee may
appoint an Authenticating Agent acceptable to the Company to authenticate Notes in accordance with Section 13.14. An Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by any such Authenticating Agent. An Authenticating Agent has the same rights as the Trustee to interact with Holders or an Affiliate of the Company. 

Section 1.05 Non-Business Day Payments. If any Interest Payment Date, the Stated
Maturity, any Redemption Date, any Net Proceeds Offer Payment Date or any Change of Control Payment Date falls on a day that is not a Business Day, then the required payment or delivery will be made on the next succeeding Business Day with the same
force and effect as if made on the date 

  
 3 

 
that the payment or delivery was due, and no additional interest will accrue on that required payment or delivery for the period from and after the Interest Payment Date, Stated Maturity,
Redemption Date, Net Proceeds Offer Payment Date or Change of Control Payment Date, as the case may be, to that next succeeding Business Day. 

Section 1.06 Temporary Notes. Until certificates representing Notes are ready for delivery, the Company may prepare and the
Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as
may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 

Section 1.07 Mutilated, Destroyed, Lost and Wrongfully Taken Notes. If (a) any mutilated Note is surrendered to the Trustee
or (b) both (i) there shall be delivered to the Company and the Trustee (A) a claim by a Holder as to the destruction, loss or wrongful taking of any Note of such Holder and a request thereby for a new replacement Note, and (B) such
indemnity bond as may be required by them to save each of them and any agent of either of them harmless and (ii) such other reasonable requirements as may be imposed by the Company as permitted by
Section 8-405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a “protected purchaser” within
the meaning of Section 8-405 of the Uniform Commercial Code, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such mutilated, destroyed, lost or
wrongfully taken Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously Outstanding. 
 In case any
such mutilated, destroyed, lost or wrongfully taken 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. 

Upon the issuance of any new Note under this Section, the Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Note issued pursuant to this Section in lieu of any destroyed, lost or wrongfully taken Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or wrongfully taken Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other
rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes. 
 Section 1.08
Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the Company, any Guarantor and the Trustee and any agent of the 

  
 4 

 
Company, any Guarantor or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of and any premium and
(subject to Article 10) any interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, any Guarantor, the Trustee nor any agent of the Company, any Guarantor or the Trustee shall
be affected by notice to the contrary. 
 Section 1.09 Cancellation. All Notes surrendered for payment, redemption, registration
of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder
which the Company has not issued and sold, and all Notes so delivered shall be promptly canceled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Notes held by the Trustee shall be disposed of according to the Trustee’s customary cancellation procedures; provided, however, that the Trustee shall not be required to destroy such canceled
Notes. 
 Section 1.10 Treasury Notes. In determining whether the Holders of the required principal amount of Notes have
concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be
considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so
disregarded. 
 Section 1.11 Holder Lists. The Trustee will preserve in as current a form as is reasonably practicable the most
recent list available to it of the names and addresses of all Holders and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days
before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of the Notes and the Company
shall otherwise comply with Trust Indenture Act Section 312(a).

(2) if interest on any Indebtedness actually incurred on the Transaction Date may optionally be determined at an interest rate
based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four Quarter Period; and 

(3) notwithstanding clauses (1) and (2) above, interest on Indebtedness determined on a fluctuating basis, to the extent
such interest is covered by agreements relating to Interest Rate Agreements, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements.

 Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 

Section 2.05 Acts of Holders; Record Dates. Any request, demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent or agents duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company and any Guarantor. Such
instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 13.01) conclusive in favor of the Trustee, the Company and any Guarantor, if made in the manner provided in
this Section. 
 Without limiting the generality of this Section 2.05, unless otherwise provided in or pursuant to
this Indenture, (i) a Holder, including a Depositary or its nominee that is a Holder of a Global Note, may give, make or take, by an agent or agents duly appointed in writing, any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted in or pursuant to this Indenture to be given, made or taken by Holders, and a Depositary or its nominee that is a Holder of a Global Note may duly appoint in writing as its agent or agents members of, or
participants in, such Depositary holding interests in such Global Note in the records of such Depositary; and (ii) with respect to any Global Note the Depositary for which is The Depository Trust Company (“DTC”), any consent or
other action given, made or taken by an “agent member” of DTC by electronic means in accordance with the Automated Tender Offer Procedures system or other Applicable Procedures of, and pursuant to authorization by, DTC shall be deemed to
constitute the “Act” of the Holder of such Global Note, and such Act shall be deemed to have been delivered to the Company, any Guarantor and the Trustee upon the delivery by DTC of an “agent’s message” or other notice of
such consent or other action having been so given, made or taken in accordance with the Applicable Procedures of DTC. 

  
 48 

 The fact and date of the execution by any Person of any such instrument or writing may be proved
by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the
execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such
instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 

None of the Trustee or agents shall have any responsibility or obligation to any beneficial owner of an interest in a global note, any agent
member or other member of, or a participant in, DTC or other person with respect to the accuracy of the records of DTC or any nominee or participant or member thereof, with respect to any ownership interest in the notes or with respect to the
delivery to any agent member or other participant, member, beneficial owner or other person (other than DTC) of any notice or the payment of any amount or delivery of any notes (or other security or property) under or with respect to such notes. All
notices and communications to be given to the holders and all payments to be made to holders in respect of the notes shall be given or made only to or upon the order of the registered holders (which shall be DTC or its nominee in the case of a
global note). The rights of beneficial owners in any global note shall be exercised only through DTC, subject to its applicable rules and procedures. The Trustee and agents may rely and shall be fully protected in relying upon information furnished
by DTC with respect to its agent members and other members, participants and any beneficial owners. 
 Any request, demand, authorization,
direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the Company or any Guarantor in reliance thereon, whether or not notation of such action is made upon such Note. 

The Company and any Guarantor may set any day as a record date for the purpose of determining the Holders of Outstanding Notes entitled to
give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Notes, provided that neither the Company nor such Guarantor
may set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving, making or taking of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to
this paragraph, the Holders of Outstanding Notes on such record date, and no other Holders, shall be entitled to give, make or take the relevant action, whether or not such Holders remain Holders after such record date; provided, however,
that no such action shall be effective hereunder unless given, made or taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall be
construed to prevent the Company or any Guarantor from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no
action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action given, made or taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is
given, made or taken. Promptly after any record date is set pursuant to this 

  
 49 

 
paragraph, the Company or such Guarantor, as the case may be, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Notes in the manner set forth in Sections 2.06 and 2.07.

respect to such Notes. If any record date is set pursuant to this paragraph, the Holders of Outstanding Notes on such record date, and no other Holders, shall be entitled to give, make or take such notice, declaration, request or direction, whether
or not such Holders remain Holders after such record date; provided, however, that no such action shall be effective hereunder unless given, made or taken on or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Notes on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon
the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action given, made or taken by Holders of the requisite
principal amount of Outstanding Notes on the date such action is given, made or taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Company and any Guarantor in writing and to each Holder of Notes in the manner set forth in Sections 2.06. 

With respect to any record date set pursuant to this Section, the party hereto which sets such record date may designate any day as the
“Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Notes in the manner set forth in Section 2.07, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this
Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date to an earlier day
as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 

Without limiting the foregoing, a Holder entitled hereunder to give, make or take any action hereunder with regard to any Note may do so, in
person or by an agent duly appointed in writing, with regard to all or any part of the principal amount of such Note. 
 Section 2.06
Notices, Etc. to Trustee, Company and Guarantors. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished
to, or filed with, (1) the Trustee by any Holder or by the Company or any Guarantor shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (which may be by facsimile transmission)

  
 50 

 
to or with the Trustee in accordance with Section 14.17 or (2) the Company or a Guarantor by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company or such Guarantor, as the case may be, in accordance with Section 14.17. 

Section 2.07 Notice to Holders; Waiver. Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if
any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the
event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

Where this Indenture provides for notice of any event to a Holder of a Global Note, such notice shall be sufficiently given if given to the
Depositary for such Global Note (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. 

Section 2.08 [Reserved]. 

ARTICLE 3 
 REDEMPTION
AND PURCHASES 
 Section 3.01 Optional Redemption; Notices to Trustee. Except as described below, the Company will not be
entitled to redeem the Notes at its option prior to June 15, 2020. 
 The Notes will be redeemable, at the Company’s option, in whole at any time
or in part from time to time, on and after June 15, 2020, upon not less than 30, nor more than 60, days’ notice, at the following redemption prices (expressed as percentages of the principal amount thereof) if redeemed during the 12-month period commencing on June 15 of the years set forth below, plus, in each case, unpaid accrued interest, if any, thereon to the Redemption Date: 

 

					
	 Year
	  	 Percentage
	 
	 2020
	  	 	106.563	% 
	 2021
	  	 	104.375	% 
	 2022
	  	 	102.188	% 
	 2023 and thereafter
	  	 	100.000	% 

  
 51 

 At any time, or from time to time, on or prior to June 15, 2020, the Company may, at its
option, use all or a portion of the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes issued under this Indenture (including any Additional Notes) at a redemption price equal to
108.75% of the aggregate principal amount of the Notes to be redeemed, plus unpaid accrued interest, if any, thereon to the Redemption Date; provided that: 

(1) at least 65% of the aggregate principal amount of Notes issued under the Indenture (including any Additional Notes) remains
Outstanding immediately after giving effect to any such redemption; and 
 (2) the Company makes such redemption not more
than 180 days after the consummation of any such Equity Offering. 
 Notice of any redemption may at the Company’s discretion be subject to one or more
conditions precedent, and, in the case of redemption with the net cash proceeds of an Equity Offering, may be given prior to the completion of the related Equity Offering. 

The Notes will also be redeemable, in whole or in part, at the Company’s option at any time or from time to time, prior to June 15,
2020, at the applicable Make-Whole Price. The notice of redemption with respect to the foregoing redemption need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company shall notify the Trustee of the Make-Whole
Price with respect to any redemption promptly after the calculation, and the Trustee shall not be responsible for such calculation. 
 In
case the Company shall desire to exercise any such right of redemption, the Company shall fix a Redemption Date and give notice thereof to the Trustee. If the Redemption Date is on a date that is after a Regular Record Date and on or prior to the
Interest Payment Date to which it relates, the Company will pay any accrued and unpaid interest to a Holder on such Regular Record Date. 

The Company shall give each notice to the Trustee provided for in this Section 3.01 at least 60 days before the
Redemption Date unless the Trustee consents to a shorter period. 
 On and after the applicable Redemption Date, interest will cease to
accrue on Notes or portions thereof called for redemption as long as the Company has previously deposited with the Paying Agent for the Notes (or, if the Company or a Wholly-Owned Restricted Subsidiary is the Paying Agent, such entity has segregated
and holds in trust) funds in satisfaction of the applicable redemption price pursuant to this Indenture. 
 Section 3.02 Selection
of Notes to Be Redeemed. If fewer than all Notes Outstanding are to be redeemed, the Trustee shall select the Notes to be redeemed by lot, on a pro rata basis or any method required by DTC or any successor Depositary or, if the Notes are listed
on a national securities exchange, in compliance with the requirements of that exchange. The Trustee shall make the selection from Notes Outstanding not previously called for redemption. The Trustee may select for redemption portions of the
principal amount of Notes that have denominations larger than $2,000. Notes and portions of Notes the Trustee selects shall be in principal amounts such that the unredeemed portion of any Note shall have a principal amount of

  
 52 

 
$2,000 or multiples of $1,000 in excess thereof. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall
notify the Company promptly of the Notes or portions of Notes to be redeemed. 
 Section 3.03 Notice of Redemption. At least 30,
but not more than 60, calendar days before the Redemption Date, the Company or, at the Company’s request, the Trustee shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Notes to be redeemed. 

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

(a) the Redemption Date; 
 (b)
the redemption price; 
 (c) the name and address of the Paying Agent; 

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

(e) if fewer than all of the Outstanding Notes are to be redeemed, the certificate numbers, if any, and principal amounts of the particular
Notes to be redeemed; 
 (f) that, unless the Company defaults in making payment of such redemption price, interest, if any, on Notes called
for redemption will cease to accrue on and after the Redemption Date; and 
 (g) the CUSIP number of the Notes. 

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense;
provided that the Company makes such request at least three Business Days prior to the date by which such notice of redemption must be given to Holders in accordance with this Section 3.03; provided further
that, in all cases, the text of such notice of redemption shall be prepared by the Company. 
 The notice if given in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not any Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note selected for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any other Note. 
 Section 3.04 Effect of Notice of
Redemption. Once notice of redemption is given, Notes called for redemption become due and payable on the Redemption Date and at the redemption price stated in the notice of redemption. If less than all the Notes are to be redeemed, the notice
of redemption shall specify the CUSIP numbers of the Note to be redeemed. Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price stated in the notice of redemption. 

  
 53 

 Section 3.05 Deposit of Redemption Price. Prior to 11:00 a.m. (New York City time) on
the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Wholly-Owned Restricted Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of all Notes to be
redeemed on that date other than Notes or portions of Notes called for redemption which have been delivered by the Company to the Trustee for cancellation. If such money is then held by the Company in trust and is not required for such purpose, it
shall be discharged from such trust. 
 Section 3.06 Notes Redeemed in Part. 

(a) In the event of any redemption in part, the Company will not be required to register the transfer of or exchange any Note so selected for
redemption, in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (b) Upon surrender of a Note that is
redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unredeemed portion of the Note surrendered, or in the case of a Global
Note, the Company shall instruct the Registrar to decrease such Global Note by the principal amount of the redeemed portion of the Note surrendered. 

Section 3.07 No Limit on Other Purchases. Nothing in this Indenture or the Notes shall prohibit or limit the right of the Company
or any Affiliate of the Company from time to time to repurchase the Notes at any price in open market purchases or negotiated transactions or by tender offer or otherwise without any notice to or consent by Holders. Any Notes purchased by the
Company may, to the extent permitted by law, be held or resold or may, at the Company’s option, be delivered to the Trustee for cancellation. Any Notes delivered to the Trustee for cancellation may not be reissued or resold and will be promptly
cancelled. 
 ARTICLE 4 

COVENANTS 

Section 4.01 Payments. The Company shall promptly make all payments in respect of the Notes on the dates and in the manner
provided in the Notes or pursuant to this Indenture. Any funds to be given to the Trustee or Paying Agent shall be deposited with the Trustee or Paying Agent by 11:00 a.m. (New York City time) by the Company on the required date. If the Company
shall at any time act as its own Paying Agent with respect to the Notes, the Company will, on or before each due date of the principal of or any premium or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or
failure so to act. Subject to the applicable provisions of Section 3.01, Section 3.07, Section 4.08, and Section 4.13, the Company shall make any
required interest payments to the Person in whose name each Note is registered at 5:00 p.m. (New York City time) on the Regular Record Date for such interest payment. Principal amount, accrued interest, if any, any redemption price, Make-Whole
Price, Net Proceeds Offer Amount and any amounts due under Section 4.13 shall be considered paid on the applicable date due if on such date the Trustee or the Paying Agent holds, in accordance with this Indenture, funds
sufficient to pay all such amounts then due. 

  
 54 

 The Company will cause each Paying Agent for any Notes other than the Trustee to execute and
deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a
Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith pay to the Trustee all sums
held in trust by such Paying Agent for payment in respect of the Notes. 
 The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of the Indenture with respect to the Notes or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held
by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect
to such money. 
 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 any premium or interest on any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request (or if deposited by a Guarantor, paid to
such Guarantor on Guarantor Request), or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company or such Guarantor, as the case may
be, 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, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may, at the expense and written request of the Company or such Guarantor, as the case may be, cause to be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any
unclaimed balance of such money then remaining will be repaid to the Company or the applicable Guarantor, as the case may be. 

Section 4.02 Maintenance of Office or Agency. The Company will maintain in The New York City an office or agency of the Trustee,
Registrar and Paying Agent where Notes may be presented or surrendered for payment (“Place of Payment”), where Notes may be surrendered for registration of transfer or exchange (“Registrar”), purchase or redemption,
where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served and a register (“Security Register”) in which, subject to reasonable regulations as it may prescribe, the Company shall
provide for the registration of Notes and the transfers of Notes. The office of Deutsche Bank Trust Company Americas, Trust & Agency Services, 60 Wall Street, 16th Floor, NYC MS 60-1630, New York, NY 10005, Attention: Trust and Agency Services, Telecopier No.: (732) 578-4635, shall initially be such office or agency for all of the aforesaid purposes.
The Company shall give prompt written notice to the Trustee of the location, 

  
 55 

 
and of any change in the location, of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with any
such 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 New York
City for such purposes. 
 Section 4.03 Reports to Holders. 

(a) Whether or not required by the rules and regulations of the Commission, so long as any Notes are Outstanding, the Company shall file with
the Commission for public availability (unless the Commission will not accept such a filing, in which case the Company will, or will cause the Trustee to, furnish the Holders (upon request)): 

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on
Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of
Operations” that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries showing in reasonable detail, either on the face of the financial statements or in the footnotes thereto and in
Management’s Discussion and Analysis of Financial Condition and Results of Operations, 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 of the Company, if any (except with respect to Subsidiaries designated as Unrestricted Subsidiaries that, when taken together with all other Unrestricted Subsidiaries, are “minor” within the
meaning of Rule 3-10 of Regulation S-X, substituting 5% for 3% where applicable) 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, in each case within the time periods specified in the Commission’s rules and regulations. 

(b) In the event that any direct or indirect parent company of the Company becomes a guarantor of the Notes, the Company may satisfy its
obligations under this covenant by furnishing financial information relating to such parent; provided that (i) such financial statements are accompanied by consolidating financial information for such parent, the Company, the Subsidiary
Guarantors and the Subsidiaries of the Company that are not Subsidiary Guarantors in the manner prescribed by the Commission and (ii) such parent is not engaged in any business in any material respect other than incidental to its ownership,
directly or indirectly, of the Capital Stock of the Company. 

  
 56 

 (c) The Company also shall comply with the other provisions of Section 314(a) of the Trust
Indenture Act. 
 (d) The Company will be deemed to have furnished to the Holders the reports or information referred to in clauses
(1) and (2) of paragraph (a) of this Section 4.03 or the information referred to paragraph (b) of this Section 4.03 if the Company has posted such reports or information on the
Company Website with access to Holders. For purposes of this Indenture, the term “Company Website” means the collection of web pages that may be accessed on the World Wide Web using the URL address http://www.billbarrettcorp.com or
such other address as the Company may from time to time designate in writing to the Trustee, provided that the Trustee shall have no responsibility whatsoever to determine whether such filing has occurred. 

(e) This Section 4.03 will not impose any duty on the Company under the Sarbanes-Oxley Act of 2002 and the related
Commission rules that would not otherwise be applicable. 
 (f) Delivery of any such reports, information and documents to the Trustee is
for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any
of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates. 
 Section 4.04
Existence. Except as permitted by Section 5.01 of this Supplement Indenture, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its and any Subsidiary
Guarantor’s corporate existence. 
 Section 4.05 Covenant Suspension. 

(a) During any period of time that (x) the Notes have an Investment Grade Rating and (y) no Event of Default has occurred and is
continuing under this Indenture, the Company and its Restricted Subsidiaries shall not be subject to Sections 4.06, 4.07, 4.08, 4.09, 4.11, 4.14, 5.01(2), 5.01(3) and 5.02(3) (collectively, the “Suspended Covenants”).

 (b) If the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the
previous sentence (a “Fall-Away Period”) and, subsequently, the ratings assigned to the Notes are withdrawn or downgraded so the Notes no longer have an Investment Grade Rating, any such date a “Reversion Date,”
then the Company and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants. The ability of the Company and its Restricted Subsidiaries to make Restricted Payments after the Reversion Date will be calculated as if
the covenant governing Restricted Payments had been in effect during the entire period of time from the Issue Date. Notwithstanding the foregoing, the continued existence after the end of the Fall-Away Period of facts and circumstances or
obligations arising from transactions which occurred during a Fall-Away Period shall not constitute a breach of any Suspended Covenant set forth in this Indenture or cause an Event of Default thereunder. 

(c) The Company shall give the Trustee notice of the event of any Fall-Away Period not later than five Business Days after such date. In the
absence of such notice, the Trustee shall assume the Suspended Covenants apply and are in full force and effect. The Company shall give 

  
 57 

 
the Trustee notice of any occurrence of a Reversion Date not later than five Business Days after such Reversion Date. After any such notice of the occurrence of a Reversion Date, the Trustee
shall assume the Suspended Covenants apply and are in full force and effect. 
 Section 4.06 Limitation on Incurrence of Additional
Indebtedness and Issuance of Preferred Stock. 
 (a) Other than Permitted Indebtedness, the Company will not, and will not cause or
permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively,
“incur”) any Indebtedness (including, without limitation, Acquired Indebtedness) and the Company will not permit any of its Restricted Subsidiaries to issue any Preferred Stock; provided, however, that if no Default or
Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness or issuance of Preferred Stock, then the Company and the Restricted Subsidiaries or any of them may incur
Indebtedness and any Restricted Subsidiary may issue Preferred Stock, in each case, if on the date of the incurrence of such Indebtedness or issuance of Preferred Stock, after giving pro forma effect to the incurrence thereof and the receipt
and application of the proceeds therefrom, the Company’s Consolidated EBITDAX Coverage Ratio would have been greater than 2.25 to 1.0. 

(b) For purposes of determining any particular amount of Indebtedness under this covenant, (i) guarantees of, or obligations in respect
of letters of credit relating to, Indebtedness otherwise included in the determination of such amount shall not also be included and (ii) if obligations in respect of letters of credit are incurred pursuant to a Credit Facility and are being
treated as incurred pursuant to clause (2) of the definition of “Permitted Indebtedness” and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included. 

(c) Indebtedness or Preferred Stock of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger,
consolidation, acquisition of Capital Stock or otherwise) or is merged with or into the Company or any Restricted Subsidiary or which is secured by a Lien on an asset acquired by the Company or a Restricted Subsidiary (whether or not such
Indebtedness is assumed by the acquiring Person) shall be deemed incurred at the time the Person becomes a Restricted Subsidiary or at the time of the asset acquisition, as the case may be. 

(d) The Company will not, and will not permit any Subsidiary Guarantor to, incur any Indebtedness which by its terms (or by the terms of any
agreement governing such Indebtedness) is subordinated in right of payment to any Indebtedness of the Company or such Subsidiary Guarantor, as the case may be, other than the Notes and the Subsidiary Guarantees, unless such Indebtedness is also by
its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate in right of payment to the Notes or the Subsidiary Guarantee of such Subsidiary Guarantor, as the case may be, pursuant to subordination provisions
that are at least as favorable to the holders of the Notes or such Subsidiary Guarantee as the subordination provisions of such Indebtedness (or agreement). 

(e) For purposes of this Indenture, no Indebtedness will be deemed to be subordinate or junior in right of payment to other Indebtedness
solely by virtue of not having the benefit of a Lien on assets, or guarantee of a Person, that benefits the other Indebtedness or having the benefit of such a Lien or guarantee ranking subordinate or junior to a Lien or guarantee benefiting the
other Indebtedness. 

  
 58 

 Section 4.07 Limitation on Restricted Payments. The Company will not, and will not
cause or permit any of its Restricted Subsidiaries to, directly or indirectly: 
 (1) declare or pay any dividend or make any
distribution (other than dividends or distributions made to the Company or any Restricted Subsidiary and other than any dividends or distributions payable solely in Qualified Capital Stock of the Company) on or in respect of shares of the Capital
Stock of the Company or any Restricted Subsidiary to holders of such Capital Stock; 
 (2) purchase, redeem or otherwise
acquire or retire for value any Capital Stock of the Company or any Restricted Subsidiary (or make any other payment on account of, or set apart money for a sinking fund or other analogous fund for the purchase, redemption or other acquisition or
retirement for value of, any Capital Stock of the Company or any Restricted Subsidiary) other than through the exchange therefor solely of Qualified Capital Stock of the Company and other than any acquisition or retirement for value from, or payment
to, the Company or any Restricted Subsidiary; 
 (3) make any principal payment on, purchase, defease, redeem, prepay,
decrease or otherwise acquire or retire for value before twelve months prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Indebtedness of the Company or a Subsidiary Guarantor that is subordinate or
junior in right of payment to the Notes or such Subsidiary Guarantor’s Subsidiary Guarantee, as the case may be (other than a purchase, repurchase or other acquisition of any such subordinated or junior Indebtedness that is so purchased,
repurchased or otherwise acquired in anticipation of satisfying a sinking fund obligation, principal installment or payment at final maturity, in each case due within 120 days of the date of such purchase, repurchase or other acquisition); or 

(4) make any Investment (other than a Permitted Investment) in any other Person; 

(each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a “Restricted Payment”; provided,
however, that no Permitted Investment shall be deemed to be a Restricted Payment), if at the time of such Restricted Payment or immediately after giving effect thereto: 

(i) a Default or an Event of Default shall have occurred and be continuing; 

(ii) the Company is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in
compliance with Section 4.06(a); or 

  
 59 

 (iii) the aggregate amount of Restricted Payments (including such proposed
Restricted Payment) made after the Measurement Date (the amount expended for such purposes, if other than in cash, being the Fair Market Value of such property as determined in good faith by the Board of Directors of the Company) shall exceed the
sum (without duplication) of: 
 (a) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income
shall be a loss, minus 100% of such loss) of the Company earned after the Measurement Date and on or prior to the last date of the Company’s fiscal quarter immediately preceding such Restricted Payment (treating such period as a single
accounting period); plus 
 (b) 100% of the aggregate net cash proceeds, or the Fair Market Value of Property
(including any Property received in any Asset Acquisition or other acquisition) other than cash, received by the Company from any Person (other than a Restricted Subsidiary of the Company) from the issuance and sale of Qualified Capital Stock of the
Company after the Measurement Date (excluding any net cash proceeds from an Equity Offering used to redeem the Notes); plus 

(c) 100% of the aggregate net cash proceeds, or the Fair Market Value of Property (including any Property received in any Asset
Acquisition or other acquisition) other than cash, of any equity contribution received by the Company from a holder of the Company’s Capital Stock after the Measurement Date (excluding any net cash proceeds from an Equity Offering to the extent
used to redeem the Notes); plus 
 (d) an amount equal to the net reduction in Investments in Unrestricted
Subsidiaries resulting from dividends, interest payments, distributions, redemptions or repurchases, sales or other dispositions thereof, repayments of loans or advances, or other transfers of cash or Properties (including transfers as a result of
merger or liquidation), in each case to the Company or to any Restricted Subsidiary of the Company from Unrestricted Subsidiaries (but without duplication of any such amount included in calculating cumulative Consolidated Net Income of the Company),
or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (in each case valued as provided in Section 4.12), not to exceed, in the case of any such redesignation, the amount of Investments previously
made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary and which was treated as a Restricted Payment under this Indenture; plus 

(e) the amount by which Indebtedness of the Company is reduced on the consolidated balance sheet of the Company and its
Restricted Subsidiaries upon the conversion or exchange subsequent to the Measurement Date of any Indebtedness of the Company or its Restricted Subsidiaries that is convertible or exchangeable for Qualified Capital Stock of the Company (less the
amount of any cash, or the Fair Market Value of any other property, distributed by the Company to the holder of such Indebtedness upon such conversion or exchange); provided, 

  
 60 

 
however, that the foregoing amount shall not exceed the Net Cash Proceeds, or the Fair Market Value of Property (including any Property received in any Asset Acquisition or other
acquisition) other than cash, received by the Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding Net Cash Proceeds from sales to a Restricted Subsidiary of the Company); plus 

(f) an amount equal to the net reduction in Investments (other than Permitted Investments) resulting from dividends,
distributions, redemptions or repurchases, proceeds of sales or other dispositions thereof, interest payments, repayments of loans or advances, or other transfers of cash or Properties (including transfers as a result of merger or liquidation), in
each case to the Company or to any Restricted Subsidiary of the Company from any Person (other than the Company or a Restricted Subsidiary), or from the obligation underlying any guarantee previously entered into by the Company or a Restricted
Subsidiary no longer existing (and without such guarantee having been called upon), in each case not to exceed the amount in respect of such Investment which had been treated as a Restricted Payment (but without duplication of any such amount
included in calculating cumulative Consolidated Net Income of the Company). 
 Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph shall not prohibit: 
 (1) the payment of any dividend or redemption payment or the making of any

(2) the acquisition of any Capital Stock of the Company or any Restricted Subsidiary, either (i) solely in exchange for

(3) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of any Indebtedness of the
Company or any Subsidiary Guarantor that is subordinate or junior in right of payment to the Notes or such Subsidiary Guarantor’s Subsidiary Guarantee, as the case may be, either (i) solely in exchange for Qualified Capital Stock of the
Company, (ii) through the application of the net proceeds of a substantially concurrent sale for cash (other than to a Restricted Subsidiary of the Company) of (a) Qualified Capital Stock of the Company or (b) Refinancing Indebtedness
or (iii) solely in exchange for Indebtedness constituting Refinancing Indebtedness; 
 (4) the purchase, repurchase,
redemption, defeasance or other acquisition or retirement for value of any Disqualified Stock of the Company or any Subsidiary Guarantor either (i) through the application of the net proceeds of a substantially concurrent sale for cash (other

 61 

 (5) if no Default or Event of Default shall have occurred and be continuing, the
redemption or repurchase of equity interests in the Company held by then present or former officers, directors or employees of the Company; provided, that the aggregate cash consideration paid for all such redemptions or repurchases in any
calendar year shall not exceed $2.0 million plus (A) the cash proceeds received during such calendar year by the Company or any of its Restricted Subsidiaries from the sale of the Company’s Qualified Capital Stock to any such
officers, directors or employees (provided that the amount of such cash proceeds utilized for any such redemption or repurchase will not increase the amount available for Restricted Payments under clause (iii)(b) of the immediately preceding
paragraph) plus (B) the cash proceeds of key man life insurance policies received during such calendar year by the Company and its Restricted Subsidiaries (with unused amounts in any calendar year being carried forward to succeeding
calendar years); 
 (6) if no Default or Event of Default shall have occurred and be continuing, repurchases of Indebtedness

the event of a Change of Control or (ii) 100% of the principal amount of such subordinated or junior Indebtedness and accrued and unpaid interest thereon in the event of an Asset Sale, in each case plus accrued interest, in connection with any
change of control offer or asset sale offer required by the terms of such Indebtedness, but only if: 
 (a) in the case of a
Change of Control, the Company has first complied with and fully satisfied its obligations under the provisions described under Section 4.13; or 

(b) in the case of an Asset Sale, the Company has complied with and fully satisfied its obligations in accordance with the
covenant under Section 4.08;

 62 

 (10) the payment of any dividend or any similar distribution by a Restricted

Stock on a pro rata basis based on their respective holdings of such Qualified Capital Stock; 
 (11) the defeasance,
repurchase, redemption or other acquisition or retirement for value of any Capital Stock of the Company or any Restricted Subsidiary held by any current or former officers, directors or employees of the Company or any of its Restricted Subsidiaries

 (12) any payments to dissenting stockholders not to exceed $5.0 million in the aggregate after the Issue Date
(x) pursuant to applicable law or (y) in connection with the settlement or other satisfaction of claims made pursuant to or in connection with a consolidation, merger or transfer of assets in connection with a transaction that is not
prohibited by this Indenture; 
 (13) any redemption of share purchase rights at a redemption price not to exceed $0.01 per
right; 
 (14) the purchase or redemption of any Acquired Subordinated Indebtedness of the Company or any Subsidiary
Guarantor, by application of (i) cash provided from operations in the ordinary course of business or (ii) proceeds from borrowings under the revolving portion of the Senior Credit Facility (so long as within 30 days prior to such purchase
or redemption, a corresponding amount of borrowings under the revolving portion of the Senior Credit Facility was repaid from cash provided from operations in the ordinary course of business); provided, in any such case, that the Company is
able to incur an additional $1.00 of Indebtedness pursuant to Section 4.06(a) after giving effect to such purchase or redemption; provided, further, that this clause (14) shall not permit the application of any proceeds
from any other borrowings under any Credit Facility to effect any such purchase or redemption; or 
 (15) any other
Restricted Payments, which when combined with any other outstanding Restricted Payments made pursuant to this clause (15), does not exceed the greater of (a) $30.0 million and (b) 2.0% of Adjusted Consolidated Net Tangible Assets determined at
the time of such Restricted Payment. 
 In determining the aggregate amount of Restricted Payments after the Measurement Date in accordance with clause
(iii) of the second preceding paragraph, amounts expended pursuant to clauses (1), (2), (3)(i), (3)(ii)(a), (7), (12) and (13) of the immediately preceding paragraph shall be included in such calculation, and amounts expended pursuant to
clauses (3)(ii)(b), (3)(iii), (4), (5), (6), (8), (9), (10), (11), (14) and (15) of the immediately preceding paragraph shall be excluded from such calculation. In determining the aggregate net cash proceeds or Fair Market Value of Property
other than cash received by the Company from the issuance and sale of Qualified Capital Stock in accordance with clause (3)(b) of the second preceding paragraph, 

  
 63 

 
amounts of cash received by the Company pursuant to clauses (2)(ii) or (3)(ii)(a), or the Fair Market Value of Capital Stock of the Company or any Restricted Subsidiary or Indebtedness of the
Company or any Subsidiary Guarantor acquired or retired for value pursuant to clauses (2)(i) or (3)(i) of the immediately preceding paragraph shall be included in such calculation. For purposes of determining compliance with this covenant, in the
event that a Restricted Payment meets the criteria of more than one of the exceptions described in (1) through (15) above or is entitled to be made pursuant to the first paragraph of this covenant, the Company shall, in its sole discretion,
classify such Restricted Payment, or later classify, reclassify or re-divide all or a portion of such Restricted Payment, in any manner that complies with this covenant. 

A sale will be deemed to be “substantially concurrent” if the related purchase, repurchase, redemption, defeasance, satisfaction and
discharge, retirement or other acquisition for value or payment of principal occurs within 90 days before or after such sale. 

Section 4.08 Limitation on Asset Sales. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless: 
 (1) the Company or the applicable Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets sold or otherwise disposed of (as determined in good faith by the Company’s Board of Directors); 

(2) either (a) at least 75% of the consideration received by the Company or such Restricted Subsidiary, as the case may
be, from such Asset Sale shall be in the form of cash or Cash Equivalents and is received at the time of such disposition or (b) the Fair Market Value (determined at the time of receipt) of all forms of consideration other than cash and Cash
Equivalents received for all Asset Sales since the Issue Date does not exceed in the aggregate 15% of the Adjusted Consolidated Net Tangible Assets of the Company at the time such determination is made; and 

(3) the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale
within 360 days of receipt thereof either: 
 (a) to repay or prepay Indebtedness outstanding under the Senior Credit
Facility (or, if the Senior Credit Facility is no longer in existence, any of the Credit Facilities); 
 (b) to repay or
prepay any Indebtedness of the Company that is secured by a Lien permitted to be incurred pursuant to Section 4.10; 

(c) to make an investment (including, without limitation, capital expenditures) in (i) properties or assets that replace
the properties or assets that were the subject of such Asset Sale or (ii) properties or assets that will be used in the Crude Oil and Natural Gas Business of the Company and its Restricted Subsidiaries or in businesses reasonably related
thereto (collectively, “Replacement Assets”); 

  
 64 

 (d) to make a Permitted Industry Investment or to acquire or make an investment
in Crude Oil and Natural Gas Related Assets; 
 (e) to the extent not included in (c) or (d) above, any investment in
(i) Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or a Restricted Subsidiary, (ii) Capital Stock constituting a minority interest in any Person that at
such time is a Restricted Subsidiary, and (iii) Capital Stock of any Subsidiary of the Company; provided that all the Capital Stock of such Subsidiary held by the Company or any of its Restricted Subsidiaries shall entitle the Company or
such Restricted Subsidiary to not less than a pro rata share of all dividends or other distributions made by such Subsidiary upon any of such Capital Stock; or 

(f) to make a combination of prepayment and investment permitted by the foregoing clauses (3)(a) through (3)(e). 

On the 361st day after an Asset Sale or such earlier date, if any, as the Board of
Directors of the Company determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(a) through (3)(f) of the immediately preceding paragraph (each a “Net Proceeds Offer Trigger Date”), such
aggregate amount of Net Cash Proceeds which have been received by the Company or such Restricted Subsidiary but which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (3)(a) through (3)(f) of the
immediately preceding paragraph (each a “Net Proceeds Offer Amount”) shall be applied by the Company or such Restricted Subsidiary, as the case may be, to make an offer to purchase (a “Net Proceeds Offer”) on a date
(the “Net Proceeds Offer Payment Date”) not less than 30, nor more than 45, days following the applicable Net Proceeds Offer Trigger Date, from all Holders and, to the extent required by the terms of any Pari Passu Indebtedness, the
holders of such Pari Passu Indebtedness, on a pro rata basis, that principal amount of Notes (and Pari Passu Indebtedness) purchasable with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount of the Notes (and Pari
Passu Indebtedness) to be purchased (or, in the event such other Pari Passu Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof), plus unpaid accrued interest, if any, thereon to the date of purchase;
provided, however, that if at any time consideration other than cash or Cash Equivalents received by the Company or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise
disposed of for cash or Cash Equivalents (other than interest received with respect to any such non-cash or non-Cash Equivalents consideration), then such conversion or
disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this covenant. 

The Company may defer the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of
$40.0 million resulting from one or more Asset Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $40.0 million shall be applied as required pursuant to this covenant). Pending
application of Net Cash Proceeds pursuant to this covenant, such Net Cash Proceeds may be temporarily invested in Cash Equivalents or applied to temporarily reduce revolving credit indebtedness. 

  
 65 

 If the Net Proceeds Offer Payment Date is on or after an interest Regular Record Date and on or
before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such Regular Record Date, and no additional interest will be payable to holders who
tender Notes pursuant to the Net Proceeds Offer. 
 Notwithstanding the first two paragraphs of this covenant, the Company and its
Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such paragraphs to the extent that: 

(1) the consideration for such Asset Sale constitutes Replacement Assets and/or Crude Oil and Natural Gas Related Assets and/or
the assumption of obligations secured by Liens that burden some or all of the assets being sold and/or cash or Cash Equivalents; provided that, in the case of any such assumption, (a) the Person assuming such obligations shall have no
recourse with respect to such obligations to the Company or any of its Restricted Subsidiaries and (b) no assets of the Company or any of its Restricted Subsidiaries (other than those assets being sold) are subject to such Liens; and 

(2) such Asset Sale is for Fair Market Value; provided that at least 75% of the total consideration received by the
Company or any of its Restricted Subsidiaries in connection with any such Asset Sale shall be in the form of Replacement Assets and Crude Oil and Natural Gas Related Assets, the assumption of obligations secured by Liens described in (1) above,
cash or Cash Equivalents, or any combination of the foregoing, and that any Net Cash Proceeds so received shall be subject to the provisions of clause (3) of the first paragraph and to the provisions of the second paragraph of this covenant.

 For the purposes of clause (2) of both the first and immediately preceding paragraphs of this covenant and for the purposes of
clause (1) of the immediately preceding paragraph, the following are deemed to be cash or Cash Equivalents: 
 (1) the
assumption of Indebtedness or other liabilities shown on the balance sheet of the Company (other than obligations in respect of Disqualified Stock of the Company) or any Restricted Subsidiary (other than obligations in respect of Disqualified Stock
or Preferred Stock of a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness or liabilities in connection with such Asset Sale (or in lieu of such a release, the agreement of the
acquiror or its parent company to indemnify and hold the Company or such Restricted Subsidiary harmless from and against any loss, liability or cost in respect of such assumed Indebtedness or liabilities accompanied by the posting of a letter of
credit (issued by a commercial bank that has an Investment Grade Rating) in favor of the Company or such Restricted Subsidiary for the full amount of the liability and for so long as the liability remains outstanding; provided,
however, that such indemnifying party (or its long-term debt securities) shall have an Investment Grade Rating (with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such
indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating) at the time the indemnity is entered into); and 

(2) securities received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or
such Restricted Subsidiary into cash within 180 days of the Asset Sale, to the extent of cash received in that conversion. 

  
 66 

 The requirement of clause 3(c), 3(d) or 3(e) above shall be deemed to be satisfied if an
agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or investment referred to therein is entered into by the Company or any Restricted Subsidiary within the time period specified in clause
(3) and such Net Cash Proceeds are subsequently applied in accordance with such agreement within six months following such agreement. 

Notice of each Net Proceeds Offer will be mailed to the record Holders as shown on the register of Holders within 30 days following the Net
Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in this Indenture. Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their Notes in whole or in part in exchange for
cash with the form entitled “Option of Holder to Elect to Purchase” on the reverse of the Note completed to the Paying Agent for the Notes at the address specified in the notice of the Net Proceeds Offer. To the extent Holders properly
tender Notes and holders of Pari Passu Indebtedness properly tender such Indebtedness with an aggregate principal amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders and Pari Passu Indebtedness will be purchased on a pro
rata basis (based on principal amounts of Notes and Pari Passu Indebtedness (or, in the case of Pari Passu Indebtedness issued with significant original issue discount based on the accreted value thereof) tendered). A Net Proceeds Offer shall
remain open for a period of 20 Business Days or such longer period as may be required by law. 
 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
pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Asset Sale” provisions of this Indenture, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under the “Asset Sale” provisions of this Indenture by virtue thereof. 

If all or any portion of any Net Proceeds Offer Amount remains after consummation of a Net Proceeds Offer, the Company may use such remaining
portion of such Net Proceeds Offer Amount for any purpose not otherwise prohibited by this Indenture. 
 Section 4.09 Limitation on
Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or
become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay
dividends or make any other distributions on or in respect of its Capital Stock (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being
paid on Common Stock shall not be deemed a restriction on the ability to pay dividends or make distributions on or in respect of Capital Stock); 

  
 67 

 (2) make loans or advances, or to pay any Indebtedness or other obligation owed,
to the Company or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made by a Restricted Subsidiary to the Company or any Restricted Subsidiary to other Indebtedness or obligations incurred or owed by
the Company or such other Restricted Subsidiary, or of Indebtedness or any other obligation owed by any Restricted Subsidiary to the Company or any Restricted Subsidiary to other Indebtedness or obligations incurred or owed by such Restricted
Subsidiary shall not be deemed a restriction on the ability of a Restricted Subsidiary to make loans or advances or to pay such Indebtedness or such other obligation); 

(3) guarantee any Indebtedness or any other obligation of the Company or any Restricted Subsidiary; or 

(4) transfer any of its property or assets to the Company or any other Restricted Subsidiary, 

except for such encumbrances or restrictions existing under or by reason of: 

(1) With respect to clauses (1)-(4) above: 

(a) applicable law; 

(b) any encumbrance or restriction pursuant to or by reason of an agreement in effect at the Issue Date; 

(c) (i) this Indenture or any other indentures governing Pari Passu Indebtedness; provided, however, that the
provisions relating to such encumbrances or restriction contained in any such other indenture are no less favorable to the Holders in any material respect as determined by the Board of Directors of the Company in their reasonable and good faith
judgment than the provisions relating to such encumbrances or restrictions contained in this Indenture or (ii) instruments governing other Indebtedness of the Company or any of its Restricted Subsidiaries permitted to be incurred pursuant to an
agreement entered into subsequent to the Issue Date in accordance with Section 4.06; provided that the provisions relating to such encumbrance or restriction contained in such instruments are not materially less
favorable to the Company and its Restricted Subsidiaries taken as a whole, as determined by the Company in good faith, than the provisions contained in the Senior Credit Facility and in this Indenture as in effect on the Issue Date; 

(d) the Senior Credit Facility; 

(e) customary encumbrances and restrictions contained in agreements of the types described in the definition of “Permitted
Industry Investments”; 

  
 68

or the properties or assets of the Person so acquired; 
 (h) customary restrictions with respect to a Restricted Subsidiary
of the Company pursuant to an agreement that has been entered into for the sale or disposition of Capital Stock or assets of such Restricted Subsidiary to be consummated in accordance with the terms of this Indenture solely in respect of the assets
or Capital Stock to be sold or disposed of; 
 (i) any instrument governing a Permitted Lien, to the extent and only to the
extent such instrument restricts the transfer or other disposition of assets subject to such Permitted Lien; 
 (j)
encumbrances and restrictions contained in contracts entered into in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Company
and the Restricted Subsidiaries to realize the value of, property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary; 

(k) an agreement governing Refinancing Indebtedness incurred to Refinance the Indebtedness issued, assumed or incurred pursuant
to an agreement referred to in clause (b), (c), (d) or (g) above or this clause (k), or contained in any amendment to an agreement referred to in clause (b), (c), (d) or (g) above or this clause (k); provided, however, that
the provisions relating to such encumbrance or restriction contained in any such agreement governing Refinancing Indebtedness or amended agreement are, taken as a whole, no less favorable to the Holders in any material respect as determined by the
Board of Directors of the Company in their reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in the applicable agreement referred to in such clause (b), (c), (d) or (g) or this clause
(k); 
 (l) Commodity Agreements, Currency Agreements or Interest Rate Agreements permitted from time to time under this
Indenture; 
 (m) the issuance of Preferred Stock by a Restricted Subsidiary or the payment of dividends thereon in
accordance with the terms thereof; provided that issuance of such Preferred Stock is permitted pursuant to Section 4.06 and the terms of such Preferred Stock do not expressly restrict the ability of a Restricted
Subsidiary to pay dividends or make any other distributions on its Capital Stock (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 Capital Stock); and 
 (n) restrictions on cash or other deposits or net worth imposed by customers under contracts
entered into in the ordinary course of business; and 

  
 69 

 (2) with respect to clause (4) above only: 

(a) any encumbrance or restriction contained in security agreements, mortgages, purchase money agreements, Capitalized Lease
Obligations or similar instruments securing Indebtedness of a Restricted Subsidiary to the extent such encumbrance or restriction restricts the transfer of the property subject to such security agreements, mortgages, purchase money agreements or
similar instruments; 
 (b) restrictions on cash or other deposits imposed by customers under contracts entered into in the
ordinary course of business; 
 (c) provisions with respect to the disposition or distribution of assets or property in
operating agreements, joint venture agreements, development agreements, area of mutual interest agreements, unitization agreements and other agreements that are customary in the Crude Oil and Natural Gas Business and entered into in the ordinary
course of business; and 
 (d) provisions limiting the disposition or distribution of assets or property in, or transfer of
Capital Stock of, joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into (i) in the ordinary course of business, consistent with past practice or
(ii) with the approval of the Company’s Board of Directors, which limitations are applicable only to the assets, property or Capital Stock that are the subject of such agreements. 

Section 4.10 Limitation on Liens. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to,
directly or indirectly, create, incur, assume or permit or suffer to exist any Liens of any kind, which Liens secure Indebtedness, against or upon any property or assets of the Company or any of its Restricted Subsidiaries (whether owned on the
Issue Date or acquired after the Issue Date), other than Permitted Liens, unless: 
 (1) in the case of Liens securing
Indebtedness that is expressly subordinate or junior in right of payment to the Notes or any Subsidiary Guarantee, the Notes or such Subsidiary Guarantee, as the case may be, are secured by a Lien on such property, assets or proceeds that is senior
in priority to such Liens at least to the same extent as the Notes are senior in priority to such Indebtedness for so long as such Indebtedness is so secured; and 

(2) in all other cases, the Notes and the Subsidiary Guarantees are equally and ratably secured with the Indebtedness so
secured for so long as such Indebtedness is so secured. 

  
 70 

 Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall provide by
its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the initial Lien. 

Section 4.11 Limitation on Transactions with Affiliates. The Company will not, and will not cause or permit any of its Restricted
Subsidiaries to, directly or indirectly, enter into, amend or conduct any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property, the guaranteeing of any Indebtedness or
the rendering of any service) involving aggregate consideration in excess of $2.0 million with, or for the benefit of, any of their respective Affiliates (each an “Affiliate Transaction”), other than Affiliate Transactions that
are on terms that, taken as a whole, are fair and reasonable to the Company or the applicable Restricted Subsidiary and are no less favorable to the Company or the applicable Restricted Subsidiary than those that might reasonably have been obtained
in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary. 

Any Affiliate Transaction (and each series of related Affiliate Transactions which are part of a common plan) that involves aggregate payments
or other property with a Fair Market Value in excess of $25.0 million shall be approved by a majority of the disinterested members of the Board of Directors of the Company, such approval to be evidenced by a Board Resolution stating that such
Board of Directors has determined that such transaction complies with the foregoing provisions. If the Company or any Restricted Subsidiary enters into an Affiliate Transaction (or a series of related Affiliate Transactions which are part of a
common plan) that involves an aggregate Fair Market Value of more than $10.0 million, the Company shall, prior to the consummation thereof, deliver an Officers’ Certificate to the Trustee certifying that such transaction complies with the
foregoing provision. 
 The restrictions set forth in the second paragraph of this covenant shall not apply to: 

(1) reasonable fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or
consultants of the Company or any Restricted Subsidiary as determined in good faith by the disinterested members of the Board of Directors of the Company or such Restricted Subsidiary, as the case may be; 

(2) transactions exclusively between or among the Company and any of its Restricted Subsidiaries or exclusively between or
among such Restricted Subsidiaries; provided, however, that such transactions are not otherwise prohibited by this Indenture; 

(3) any Investment or other Restricted Payments permitted by this Indenture; 

(4) any issuance of securities or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding
of, employment or severance arrangements, stock options and stock ownership, phantom stock or other incentive compensation plans approved by the Board of Directors of the Company; 

(5) (a) loans or advances to officers, directors or employees in the ordinary course of business in accordance with the past
practices of the Company or its Restricted Subsidiaries, but in any event not to exceed $5.0 million in the aggregate outstanding at 

  
 71 

 
any one time; and (b) advances to or reimbursements of officers, directors or employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the
ordinary course of business; 
 (6) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company
to, or the receipt by the Company of any capital contribution from, the holders of its Capital Stock; 
 (7) transactions and
arrangements in effect, or effected in accordance with agreements or arrangements in effect, on the Issue Date, including any modifications, extensions or renewals thereof that do not adversely affect the Company and its Restricted Subsidiaries,
considered as a single enterprise in any material respect as compared to the kinds of transactions, arrangements or agreements in effect on the Issue Date; 

(8) transactions with a Person that is an Affiliate of the Company solely because the Company owns, directly or through a
Subsidiary, an equity interest in, or controls, such Person; 
 (9) transactions with any joint venture or similar entity,
which joint venture or similar entity is an Affiliate of the Company solely because an Affiliate of the Company is a general partner in such joint venture or similar entity; provided that Affiliates (all such Affiliates taken together) of the
Company (other than the Company and its Restricted Subsidiaries) do not in the aggregate beneficially own or hold, directly or indirectly, 10% or more of any class of voting interests in such joint venture or similar entity; 

(10) (a) guarantees by the Company or any of its Restricted Subsidiaries of performance of obligations of Unrestricted
Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (b) pledges by the Company or any Restricted Subsidiary of Capital Stock in Unrestricted Subsidiaries for the benefit of
lenders or other creditors of Unrestricted Subsidiaries; and 
 (11) any transaction in which the Company or any of its
Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an Independent Advisor 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 the first paragraph of this covenant. 
 Section 4.12 Limitation on Restricted and Unrestricted
Subsidiaries. At the time the Notes are originally issued, both of the Subsidiaries of the Company (Circle B Land Company LLC and Aurora Gathering, LLC) will be Restricted Subsidiaries. As the Company or any of its Subsidiaries forms or acquires
Subsidiaries, each newly formed or acquired Subsidiary shall be designated by the Company’s Board of Directors as a Restricted Subsidiary or an Unrestricted Subsidiary; provided that (1) any Subsidiary of any already existing
Unrestricted Subsidiary shall be (and shall be deemed designated as) an Unrestricted Subsidiary (without necessity for any Board of Directors resolution), (2) subject to the foregoing clause (1), any designation of an

  
 72 

 
Unrestricted Subsidiary (other than during any Fall-Away Period) shall be effective only if the Investment in that Subsidiary is made in compliance with Section 4.07,
and (3) subject to the foregoing clause (1), any failure by the Company’s Board of Directors to affirmatively make such a designation of a Subsidiary shall be deemed a designation (in compliance with this Indenture) of such Subsidiary as a
Restricted Subsidiary. After a Subsidiary of the Company has been designated as an Unrestricted Subsidiary, the Board of Directors of the Company may, if no Default or Event of Default would arise therefrom, redesignate such Unrestricted Subsidiary
to be a Restricted Subsidiary; provided that: 
 (1) any such redesignation shall be deemed to be an incurrence as of
the date of such redesignation (other than during any Fall-Away Period) by the Company and its Restricted Subsidiaries of the Indebtedness (if any) of such redesignated Subsidiary for purposes of Section 4.06; 

(2) unless such redesignated Subsidiary shall not have any Indebtedness outstanding, other than Indebtedness which would be
Permitted Indebtedness, no such designation shall be permitted (other than during any Fall-Away Period) if immediately after giving effect to such redesignation and the incurrence of any such additional Indebtedness the Company could not incur $1.00
of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.06(a); and 
 (3) other than
during any Fall-Away Period, such Subsidiary assumes by execution of a supplemental indenture all of the obligations of a Subsidiary Guarantor under a Subsidiary Guarantee if the aggregate Indebtedness for which such Subsidiary is an obligor or
guarantor is at least $10.0 million in aggregate principal amount. 
 After a Subsidiary of the Company has been designated as a
Restricted Subsidiary, the Board of Directors of the Company also may, if no Default or Event of Default would arise therefrom, redesignate any Restricted Subsidiary to be an Unrestricted Subsidiary if such redesignation is at that time permitted
under Section 4.07. Upon such permitted redesignation, such former Restricted Subsidiary’s Subsidiary Guarantee will be released. 

Any such designation or redesignation (other than any deemed designation referred to in clause (1) of the proviso to the first paragraph
of this covenant) of an Unrestricted Subsidiary by the Board of Directors shall be evidenced to the Trustee by the filing with the Trustee of a certified copy of the resolution of the Board of Directors giving effect to such designation or
redesignation and an Officers’ Certificate certifying that such designation or redesignation complied with the foregoing conditions and setting forth in reasonable detail the underlying calculations. 

For purposes of Section 4.07: 

(1) an “Investment” shall be deemed to have been made at the time any Restricted Subsidiary is designated as an
Unrestricted Subsidiary in an amount (proportionate to the Company’s equity interest in such Subsidiary) equal to the net worth of such Restricted Subsidiary at the time that such Restricted Subsidiary is designated as an Unrestricted
Subsidiary (“net worth” to be calculated based upon the Fair Market Value of the assets of such Subsidiary as of any such date of designation as such Fair Market Value is determined in good faith by the Company’s Board of
Directors); and 
 (2) any property transferred to or from an Unrestricted Subsidiary shall be valued at its Fair Market
Value at the time of such transfer as such Fair Market Value is determined in good faith by the Company’s Board of Directors. 

  
 73 

 Notwithstanding the foregoing, the Board of Directors may not designate any Subsidiary of the
Company to be an Unrestricted Subsidiary (other than during any Fall-Away Period) if, after such designation or redesignation: 

(1) the Company or any Restricted Subsidiary: 

(a) provides credit support for, or a guarantee of, any Indebtedness of such Subsidiary (including any undertaking, agreement
or instrument evidencing such Indebtedness); or 
 (b) is otherwise directly or indirectly liable for any Indebtedness of
such Subsidiary; or 
 (2) such Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property of, any
Restricted Subsidiary which (a) is not a Subsidiary of the Subsidiary to be so designated and (b) is not also then being designated as an Unrestricted Subsidiary. 

During any Fall-Away Period, a Restricted Subsidiary may be redesignated an Unrestricted Subsidiary only if such Restricted Subsidiary does
not own, at that time, Restricted Property, unless such Restricted Subsidiary constitutes, at the time of redesignation, less than 15% of the Company’s Adjusted Consolidated Net Tangible Assets. 

Section 4.13 Change of Control. 

(a) Upon the occurrence of a Change of Control, each Holder will have the right to require that the Company purchase all or any portion of
such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof, plus unpaid accrued interest, if any, thereon to the date of purchase
(subject to the right of Holders of record on the relevant Regular Record Date to receive interest on the relevant Interest Payment Date). 

(b) Within 30 days following the date upon which the Change of Control occurred, the Company must send, by first class mail, postage prepaid,
a notice to each Holder, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the following: 

(1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such
Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus unpaid accrued interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant Regular
Record Date to receive interest on the relevant Interest Payment Date); 

  
 74 

 (2) the purchase date (which shall be no earlier than 30 days nor later than 60
days from the date such notice is mailed; such purchase date, the “Change of Control Payment Date”); and 

(3) the instructions, as determined by the Company, consistent with the covenant described hereunder, that a Holder must follow
in order to have its Notes purchased. 
 (c) Holders electing to have a Note purchased pursuant to a Change of Control Offer will be
required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent for the Notes at the address specified in the notice prior to the close of business on
the third Business Day prior to the Change of Control Payment Date. If the Change of Control Payment Date is on or after an interest Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid
to the Person in whose name a Note is registered at the close of business on the Regular Record Date, and no additional interest will be payable to holders who tender pursuant to the Change of Control Offer. 

(d) The Company will not be required to make a Change of Control Offer following a Change of Control if (i) a third party makes the
Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer or (ii) notice of redemption of all Notes has been given pursuant to this Indenture as described in Section 3.03 unless there is a default in payment of the applicable redemption
price. 
 (e) Any Change of Control Offer may be made in advance of a Change of Control, and, at the Company’s discretion, conditioned
upon the occurrence of such Change of Control, if a definitive agreement is in effect for the Change of Control at the time of making the Change of Control Offer. 

(f) Neither the Board of Directors of the Company nor the Trustee may waive the covenant relating to the obligation to make a Change of
Control Offer. 
 (g) A Change of Control Offer shall remain open for a period of 20 Business Days or such longer period as may be required
by law. 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 pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Change of Control” provisions of this Indenture, the Company shall
comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the “Change of Control” provisions of this Indenture by virtue thereof. 

  
 75 

 Section 4.14 Additional Subsidiary Guarantors. If, after the Issue Date, any
Restricted Subsidiary (including any newly formed, newly acquired or newly redesignated Restricted Subsidiary but excluding any Foreign Subsidiary and further excluding any Non-Guarantor Restricted Subsidiary
if the Consolidated Net Worth of such Non-Guarantor Restricted Subsidiary, together with the Consolidated Net Worth of all other Non-Guarantor Restricted Subsidiaries,
as of such date, does not exceed $10.0 million in the aggregate) incurs or guarantees any Indebtedness, which when combined with any other such Indebtedness for which such Restricted Subsidiary is an obligor or guarantor, is at least
$10.0 million in aggregate principal amount, the Company shall cause such Restricted Subsidiary to: 
 (1) execute and
deliver to the Trustee a supplemental indenture substantially in the form set forth in Exhibit B attached hereto and otherwise in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally
guarantee all of the Company’s obligations under the Notes and the Indenture on the terms set forth in the Indenture; and 

(2) deliver to the Trustee an Opinion of Counsel that such supplemental indenture has been duly authorized, executed and
delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary in accordance with its terms. 

Thereafter, such Restricted Subsidiary shall be a Subsidiary Guarantor for all purposes of the Indenture, subject to such Restricted
Subsidiary ceasing to be a Subsidiary Guarantor when its Subsidiary Guarantee is released in accordance with the terms of the Indenture. 

In addition, to the extent the collective Consolidated Net Worth of the Non-Guarantor Restricted
Subsidiaries, as of the date of the creation of, acquisition of or Investment in a Non-Guarantor Restricted Subsidiary, exceeds $10.0 million, the Company shall, within 60 days after such date, cause one
or more of such Non-Guarantor Restricted Subsidiaries to deliver to the Trustee such a supplemental indenture and opinion as specified in clauses (1) and (2) of the second preceding paragraph (and thereby
cause such Non-Guarantor Restricted Subsidiary(ies) to cease to be Non-Guarantor Restricted Subsidiary(ies)), such that the collective Consolidated Net Worth of all
remaining Non-Guarantor Restricted Subsidiaries does not exceed $10.0 million in the aggregate. 

Section 4.15 Waiver of Covenants. The Company or any Subsidiary Guarantor may omit in any particular instance to comply with any
term, provision or condition set forth in any of Sections 4.02 through 4.14 or Article 5 of this Indenture or any other provision of the Indenture with respect to the Notes and Subsidiary Guarantees thereof (except a covenant
that under Section 8.02 cannot be amended without the consent of each Holder) if, before the time for such compliance, the Holders of a majority in principal amount (including waivers obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes) of all Outstanding Notes shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and any Subsidiary Guarantor and the duties of the Trustee in respect of
any such term, provision or condition shall remain in full 

  
 76 

 
force and effect. A waiver of compliance given by or on behalf of any Holder of Notes in connection with a purchase of, or tender or exchange offer for, such Holder’s Notes will not be
rendered invalid by such purchase, tender or exchange. 
 Section 4.16 Statement by Officers as to Default. 

(a) The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the Issue Date, an
Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of the Indenture with respect to the Notes
(without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge; 

(b) Each Subsidiary Guarantor will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the
Issue Date, a Guarantor’s Officers’ Certificate of such Guarantor, stating whether or not to the best knowledge of the signers thereof such Guarantor is in default in the performance and observance of any of the terms, provisions and
conditions of the Indenture with respect to the Notes and Subsidiary Guarantees thereof (without regard to any period of grace or requirement of notice provided hereunder) and, if such Guarantor shall be in default, specifying all such defaults and
the nature and status thereof of which they may have knowledge. 
 Section 4.17 Money for Notes Payments to Be Held in Trust. If
the Company shall at any time act as its own Paying Agent with respect to the Notes, it will, on or before each due date of the principal of or any premium or interest, if any, on the Notes, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

SUCCESSOR CORPORATION 

Section 5.01 When Company May Merge or Transfer Assets. The Company will not, in a single transaction or series of related
transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary to sell, assign, transfer, lease, convey or otherwise dispose of) all or
substantially all of the Company’s assets (determined on a consolidated basis for the Company and its Restricted Subsidiaries), unless: 

(1) either: 

(a) (i) the Company shall be the surviving or continuing entity or (ii) the sale or other disposition is by one or more
Restricted Subsidiaries to one or more other Restricted Subsidiaries; or 

  
 77 

 (b) the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition all or substantially all of the Company’s assets (as so determined) (the “Surviving Entity”): 

(x) shall be an entity organized and validly existing under the laws of the United States or any state thereof or the District
of Columbia; and 
 (y) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, the due
and punctual payment of the principal of, premium, if any, and interest on all of the Notes and the performance of every covenant of the Notes and this Indenture on the part of the Company to be performed or observed; 

(2) immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including
giving effect to any Indebtedness incurred or anticipated to be incurred or repaid in connection with or in respect of such transaction as if the same had occurred at the beginning of the applicable Four Quarter Period) and the application of any
net proceeds therefrom, the Company or such Surviving Entity, as the case may be, either (x) shall be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.06(a), or
(y) would have a Consolidated EBITDAX Coverage Ratio that is equal to or greater than the Consolidated EBITDAX Coverage Ratio of the Company immediately prior to such transaction; provided, however, that this clause (2) will
not be applicable to (A) a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Company or one or more other Restricted Subsidiaries or (B) the Company merging with an
Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction, converting to an entity taxable for federal income tax purposes as a corporation or a combination of the foregoing; 

(3) immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including,
without limitation, giving effect to any Indebtedness incurred or anticipated to be incurred or repaid and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred or be continuing;
provided, however, that this clause (3) will not be applicable to a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Company or one or more other Restricted
Subsidiaries; and 
 (4) the Company or the Surviving Entity, as the case may be, shall have delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction,
such supplemental indenture complies with the applicable provisions of this 

  
 78 

 
Indenture and that all conditions precedent in this Indenture relating to such transaction have been satisfied; provided, however, that such counsel may rely, as to matters of fact,
on a certificate or certificates of officers of the Company. 
 For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries, the Capital Stock of which constitutes all or substantially all of the properties and
assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 
 Upon
any consolidation or merger or any transfer or other disposition of all or substantially all of the assets of the Company in accordance with the foregoing, in which the Company is not the Surviving Entity, the Surviving Entity formed by such
consolidation or into which the Company is merged or to which such conveyance, lease or transfer or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and
the Notes with the same effect as if such Surviving Entity had been named as such, and thereafter (except in the case of a lease of all or substantially all of the Company’s assets) the Company will be relieved of all obligations and covenants
under the Indenture and the Notes. 
 Section 5.02 When Subsidiary Guarantor May Merge or Consolidate. Each Subsidiary Guarantor (other
than any Subsidiary Guarantor whose Subsidiary Guarantee is to be released in accordance with the terms of the Subsidiary Guarantee and this Indenture in connection with any transaction complying with the provisions of this Indenture described under
Section 4.08) will not, and the Company will not cause or permit any such Subsidiary Guarantor to, consolidate with or merge with or into any Person other than the Company or another Restricted Subsidiary that is a
Subsidiary Guarantor unless: 
 (1) the entity formed by or surviving any such consolidation or merger (if other than the
Subsidiary Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is an entity organized and existing under the laws of the United States or any state thereof or the District of Columbia; 

(2) such entity (if other than the Subsidiary Guarantor) assumes by execution of a supplemental indenture all of the
obligations of the Subsidiary Guarantor under its Subsidiary Guarantee; and 
 (3) immediately after giving effect to such
transaction, no Default or Event of Default shall have occurred and be continuing. 
 Any merger or consolidation of a Subsidiary Guarantor
with and into the Company (with the Company being the surviving entity) or another Restricted Subsidiary that is a Subsidiary Guarantor need only comply with Section 5.01(4). 

Upon any consolidation or merger of any Subsidiary Guarantor in accordance with the second preceding paragraph (excluding any merger or
consolidation of a Subsidiary Guarantor whose Subsidiary Guarantee is to be released as specified in the second preceding paragraph and any merger or consolidation of a Subsidiary Guarantor referred to in the immediately

  
 79 

 
preceding paragraph) in which such Subsidiary Guarantor is not the continuing Person, the Person formed by such consolidation or into which such Subsidiary Guarantor is merged shall succeed to,
and be substituted for, and may exercise every right and power of, such Subsidiary Guarantor under this Indenture and the Notes with the same effect as if such Person had been named as such; and thereafter such Subsidiary Guarantor shall be
discharged from all obligations and covenants, this Indenture and the Notes. 
 ARTICLE 6 

DEFAULTS AND REMEDIES 

Section 6.01 Events of Default. Each of the following events shall constitute an “Event of Default” with respect
to the Notes: 
 (1) the failure to pay interest on any Notes when the same becomes due and payable and the failure continues
for a period of 30 days; 
 (2) the failure by the Company to (a) pay the principal on any Notes, when such principal
becomes due and payable, at maturity, upon redemption or otherwise, or (b) consummate a purchase of Notes when required pursuant to Section 4.08 and Section 4.13, which failure, solely in the
case of Section 4.13, continues for a period of 30 days or, solely in the case of Section 4.08, continues for a period of 30 days after the Company receives written notice specifying the default
(and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (including any Additional Notes); 

(3) the failure to comply with any other covenant contained in Article 4 or Section 5.01 of
this Indenture, which failure continues for a period of 30 days after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the Outstanding
principal amount of the Notes (including any Additional Notes) (except in the case of a failure to comply with any of the terms or provisions of (i) the first paragraph of Section 5.01, which will constitute an Event
of Default with such notice requirement but without such passage of time requirement or (ii) Section 4.03, which will constitute an Event of Default only after a period of 90 days after such notice); 

(4) the failure of the Company or any Subsidiary Guarantor to comply with its other agreements contained in the Indenture for
60 days after the Company receives written notice from the Trustee or the Holders of 25% in principal amount of the Outstanding Notes (including any Additional Notes) specifying the failure (and demanding that such failure be remedied); 

(5) a default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness of the Company or of any Restricted Subsidiary (or the payment of which is guaranteed by the Company or any Restricted Subsidiary), whether such Indebtedness exists on the Issue Date or is created thereafter, which default
(i) is caused by a failure to pay principal of or 

  
 80 

 
premium, if any, or interest on such Indebtedness after any applicable grace period provided in such Indebtedness on the date of such default (a “payment default”) or
(ii) results in the acceleration of such Indebtedness prior to its express 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 at least $50.0 million; 
 (6) one or more
judgments for the payment of money in an aggregate amount in excess of $50.0 million (unless covered by insurance by a reputable insurer as to which the insurer has not disclaimed coverage) shall have been rendered against the Company or any of
its Restricted Subsidiaries and such judgment(s) remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable; 

(7) (x) the Company or any of its Significant Subsidiaries 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 receiver of it or for any substantial part of its property; or 

(D) makes a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating
to insolvency; or 
 (y) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against the Company or any of its Significant Subsidiaries in an involuntary case; 

(B) appoints a receiver of the Company or any of its Significant Subsidiaries or for any substantial part of its property;

 (C) orders the winding up or liquidation of the Company or any of its Significant Subsidiaries; or 

(D) grants any similar relief under any foreign laws, 

and in each such case the order or decree remains unstayed and in effect for 60 days; or 

(8) any of the Subsidiary Guarantees cease to be in full force and effect or any of the Subsidiary Guarantees are declared to
be null and void or invalid and 

  
 81 

 
unenforceable or any of the Subsidiary Guarantors denies or disaffirms its liability under its Subsidiary Guarantees (other than by reason of release of a Subsidiary Guarantor in accordance with
the terms of this Indenture). 
 The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is
voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 

The Company shall deliver to the Trustee, as promptly as reasonably practicable and in any event within ten Business Days after the Company
becomes aware of the occurrence of any Default or Event of Default, written notice in the form of an Officers’ Certificate of such Default or Event of Default, unless such Default or Event of Default has been cured before the end of the ten-Business Day period. 
 Any reference in this Article 6 or elsewhere in this Indenture to
“Event of Default” shall be deemed to refer to and include only the Events of Default with respect to the Notes specified in this Section 6.01, and the term “Default” as so used in this Indenture shall
have a correlative meaning. 
 Section 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in
Section 6.01(7) with respect to the Company) occurs and is continuing, the Trustee, in the event a Responsible Officer of the Trustee has actual knowledge of such Event of Default, by notice in writing to the Company, or
the Holders of at least 25% in aggregate principal amount of the Notes (including any Additional Notes) then Outstanding by notice in writing to the Company and the Trustee, may declare the principal of, premium, if any, and accrued and unpaid
interest on all the Notes Outstanding to be immediately due and payable, which notice shall specify the Event of Default and that it is a “notice of acceleration”. Upon such a declaration, such accelerated amount shall be due and payable
immediately. If an Event of Default specified in Section 6.01(7) with respect to the Company occurs and is continuing, the unpaid principal of, premium, if any, and accrued and unpaid interest on all the Notes Outstanding
shall, automatically and without any action by the Trustee or any Holder, become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. 

Notwithstanding the foregoing, if an Event of Default specified in clause (5) of Section 6.01 shall have occurred and be continuing,
such Event of Default and any acceleration resulting therefrom shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default has been repaid, or (ii) the default relating to such Indebtedness has
been waived or cured and, if such Indebtedness has been accelerated, the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness. 

The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding by notice to the Trustee and the Company and
without notice to any other Holder may rescind and cancel any declaration of acceleration and its consequences: 
 (1) if the
rescission would not conflict with any judgment or decree; 

  
 82 

 (2) if all existing Events of Default have been cured or waived except nonpayment
of principal or interest that has become due solely because of such acceleration; 
 (3) to the extent the payment of such
interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; 

(4) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements
and advances; and 
 (5) in the event of the cure or waiver of an Event of Default of the type described in
Section 6.01(7), the Trustee shall have received an Officers’ Certificate that such Event of Default has been cured or waived. 

No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of the principal amount plus accrued and unpaid interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of the Notes 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. No remedy is exclusive of any
other remedy. All available remedies are cumulative. 
 Section 6.04 Waiver of Past Defaults. At any time prior to the
declaration of acceleration of the Notes, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding by notice to the Trustee and without notice to any other Holder may waive (including any waivers obtained in
connection with a purchase of, or tender or exchange offer for, the Notes) any existing Default or Event of Default and its consequences except an Event of Default described in Section 6.01(2)(a) and Section 6.01(1).
When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. 

Section 6.05 Control by Majority. Subject to the provisions of the Indenture and applicable law, the Holders of a majority in
aggregate principal amount of the Notes at the time Outstanding have the right to direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the
Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee reasonably determines is unduly prejudicial to the rights of any other Holder or would in the opinion of its counsel
potentially involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to the Trustee in its reasonable discretion against all losses and expenses caused by taking
or not taking such action. 

  
 83 

 Section 6.06 Limitation on Suits. Subject to Section 6.07,
a Holder may not pursue any remedy with respect to this Indenture or the Notes or for the appointment of a receiver or a trustee, unless: 

(a) such Holder shall have previously given to the Trustee written notice of a continuing Event of Default; 

(b) the Holders of at least 25% in aggregate principal amount of the Notes at the time Outstanding make a written request and
shall have offered reasonable indemnity to the Trustee to institute such proceeding as Trustee; 
 (c) the Trustee has failed
to institute such remedy within 60 days after such written notice, request and offer; and 
 (d) the Trustee has not received
from the Holders of a majority in aggregate principal amount of the Notes then Outstanding a direction inconsistent with such request within 60 days after such written notice, request and offer. 

A Holder may not use the Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder. 

Section 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of the principal amount, redemption price, Make-Whole Price, Net Proceeds Offer Amount (with respect to an Asset Sale that has been consummated), any amounts due under Section 4.13 (with respect to a
Change of Control that has occurred) or interest, if any, in respect of the Notes held by such Holder, on or after the respective due dates expressed in such Holder’s Notes or any Redemption Date, Net Proceeds Offer Payment Date or Change of
Control Payment Date, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or
Section 6.01(2)(a) occurs and is continuing, the Trustee may recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest) and
the amounts provided for in Section 13.07. 
 Section 6.09 Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, a Subsidiary Guarantor, its creditors or its
property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any receiver in any such judicial proceeding is hereby
authorized by each Holder to make 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 it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 13.07. 

  
 84 

 Section 6.10 Priorities. If the Trustee collects any money or property pursuant to
this Article 6, it shall pay out the money or property in the following order: 
 FIRST: to the Trustee for amounts
due under Section 13.07; 
 SECOND: to Holders for amounts due and unpaid on the Notes for the principal amount,
redemption price, Make-Whole Price, Net Proceeds Offer Amount (with respect to an Asset Sale that has been consummated), any amount due under Section 4.13 (with respect to a Change of Control that has occurred) or interest,
if any, as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Notes; and 

THIRD: the balance, if any, to the Company or, if applicable, the Subsidiary Guarantors. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days
before such record date, the Company shall mail to each Holder and the Trustee a notice that states the record date, the payment date and the amount to be paid. 

Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Notes at the time
Outstanding. 
 Section 6.12 Waiver of Stay or Extension Laws. The Company and the Subsidiary Guarantor (to the extent they may
lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company and the Subsidiary Guarantor (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any
power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 

  
 85 

 ARTICLE 7 

DISCHARGE OF INDENTURE 

The Indenture will be discharged and will cease to be of further effect (except as to surviving rights of registration of transfer or exchange
of the Notes, as expressly provided for in the Indenture) as to all Outstanding Notes and as to all Subsidiary Guarantees thereof, and the Trustee, upon a Company Request and at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of the Indenture with respect to such Notes and Subsidiary Guarantees, when: 
 (1)
either: 
 (a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been
replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for
cancellation; or 
 (b) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable or
will become due and payable within one year by reason of the mailing of a notice of redemption or otherwise and the Company has irrevocably deposited or caused to be deposited with the Trustee funds (constituting cash in U.S. dollars, non-callable Cash Equivalents within the meaning of clauses (1) or (2) of the definition thereof or a combination of cash in U.S. dollars and such non-callable Cash
Equivalents) in an amount sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and
interest on the Notes to the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; 

(2) the Company has paid all other sums payable under this Indenture by the Company; and 

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all
conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of
officers of the Company. 
 Notwithstanding the satisfaction and discharge of the Indenture with respect to the Notes, the obligations of
the Company to the Trustee under Section 13.07, the obligations of the Trustee to any Authenticating Agent under Section 13.14, and, if funds shall have been deposited with the Trustee pursuant to subclause (b) of Clause (1) of
this Section with respect to such Notes, the obligations of the Company under Section 4.02 and the obligations of the Trustee under the following paragraph, Section 13.06 and the last paragraph of
Section 4.01 with respect to such Notes shall survive such satisfaction and discharge. 
 Subject to the
provisions of the last paragraph of Section 4.01, all funds deposited with the Trustee pursuant to this Article 7 shall be held in trust and applied by it, 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 and any premium and interest for

  
 86 

 
whose payment such funds have been deposited with the Trustee. The Company may direct by a Company Order the investment of any funds deposited with the Trustee pursuant to this Article 7,
without distinction between principal and income, in any Cash Equivalents and from time to time the Company may direct the reinvestment of all or a portion of such funds in other Cash Equivalents. 

ARTICLE 8

accordance with the terms of this Indenture or to secure the Notes or any Guarantees;

inconsistency in the Indenture or to make any other provisions with respect to matters or questions arising under the Indenture, so long as such action will not materially adversely affect the interests of the Holders; 

(f) cure any ambiguity, defect or inconsistency; 

(g) modify or amend the Indenture to permit the qualification of the Indenture under the Trust Indenture Act;

and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts under the Indenture by more than one Trustee, pursuant to the requirements of
Section 13.11; 

  
 87 

 (j) provide for the issuance of Additional Notes as permitted by Sections 1.01
and 1.03 of this Indenture, which will have terms substantially identical to the other Notes Outstanding except as specified in Sections 1.01 and 1.03, and which will be treated, together with any other Notes Outstanding, as a single
class for all purposes of the Indenture;

description hereof and thereof contained in the Offering Memorandum relating to the Notes dated April 25, 2017; or 

(l) make any other change to the Indenture or forms or terms of the Notes that would provide any additional right or benefit to
Holders or that does not adversely affect the rights of the Holders. 
 The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 8.01 may be executed by the Company, the
Subsidiary Guarantors and the Trustee without the consent of the Holders of any of the Notes at the time Outstanding, notwithstanding any of the provisions of Section 8.02. 

After an amendment under this Section 8.01 becomes effective, the Company shall mail to Holders a notice briefly
describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 

Section 8.02 With Consent of Holders. With the consent of the Holders of a majority in aggregate principal amount of the Notes at
the time Outstanding (including the consents obtained in connection with a purchase of, or tender or exchange offer for, Notes), by Act of said Holders delivered to the Company and the Trustee, the Company, the Subsidiary Guarantors and the Trustee
may enter into any supplemental indenture to amend or supplement the Indenture or the Notes for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Notes or the Indenture or of modifying in
any manner the rights of the Holders of the Notes under the Indenture. However, no amendment, supplement or waiver may be made without the consent of each Holder of Notes Outstanding affected thereby if such amendment, supplement or waiver would
(with respect to Notes held by any non-consenting Holder): 
 (a) reduce the amount
of Notes whose Holders must consent to an amendment; 
 (b) reduce the rate of or change or have the effect of changing the
time for payment of interest, including defaulted interest, on any Notes; 

  
 88 

 (c) reduce the principal of or change or have the effect of changing the fixed
maturity of any Notes; 
 (d) reduce the amount payable upon the redemption of any Note or change the time at which any Note

include any purchase or repurchase of Notes; 
 (e) make the Notes payable in money other than that stated in the Notes; 

(f) make any change in provisions of the Indenture protecting the right of each Holder to receive payment of principal of and
interest on such Note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of Default; 

(g) amend, change or modify in any material respect the obligation of the Company (A) to make and consummate a Change of
Control Offer in the event a Change of Control has occurred or (B) to make and consummate a Net Proceeds Offer with respect to any Asset Sale that has been consummated or modify any of the provisions or definitions applicable to any such Change
of Control or Asset Sale that has occurred or been consummated; 
 (h) modify or change any provision of the Indenture or the
related definitions affecting the ranking in right of payment of the Notes or any Subsidiary Guarantee as senior unsecured indebtedness of the Company or the relevant Subsidiary Guarantors, as the case may be, in a manner which adversely affects the
Holders; 
 (i) to provide for the issuance of Additional Notes under the Indenture in accordance with the limitations set
forth in the Indenture; or 
 (j) release any Subsidiary Guarantor from any of its obligations under its Subsidiary Guarantee
or the Indenture otherwise than in accordance with the terms of the Indenture. 
 It shall not be necessary for the consent of the Holders
under this Section 8.02 to approve the particular form of any proposed amendment or supplemental indenture, but it shall be sufficient if such consent approves the substance thereof. 

A consent to any indenture supplemental hereto by or on behalf of any Holder of Notes given in connection with a purchase of, or tender or
exchange offer for, such Holder’s Notes will not be rendered invalid by such purchase, tender or exchange. 
 After a supplemental
indenture under this Section 8.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment or supplemental indenture. Notwithstanding anything in this
Section 8.02 to the contrary, the failure of the Company to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

  
 89 

 Upon the request of the Company, accompanied by a copy of a Board Resolution authorizing the
execution of any such supplemental indenture, and upon the filing with the Trustee of the Act of Holders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects
the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Section 8.03 Compliance with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to
the requirements of the Trust Indenture Act. 
 Section 8.04 Notation on or Exchange of Notes. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange
for Outstanding Notes. 
 Section 8.05 Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental
indenture authorized pursuant to this Article 8 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In
signing such supplemental indenture the Trustee shall be provided with, and (subject to the provisions of Section 13.01 hereof) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture and represents the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. 

Section 8.06 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, 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. 

ARTICLE 9 
 LEGAL
DEFEASANCE AND COVENANT DEFEASANCE 
 Section 9.01 Legal Defeasance and Covenant Defeasance. The Company may, at its option
and at any time, elect to have its obligations and the corresponding obligations of the Subsidiary Guarantors discharged with respect to the Outstanding Notes (“Legal Defeasance”). Such Legal Defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes, and satisfied all of its obligations with respect to the Notes, except for: 

(1) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when
such payments are due; 

  
 90 

 (2) the Company’s obligations with respect to the Notes concerning issuing
temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments; 

(3) the rights, powers, trust, duties and immunities of the Trustee and the Company’s obligations in connection therewith;
and 
 (4) the Legal Defeasance provisions of this Indenture. 

In addition, the Company may, at its option and at any time, elect to terminate its obligations under Section 4.03,
Sections 4.06 through 4.14 and the operation of Section 6.01(2)(b), Sections 6.01(3) through (6) and Section 6.01(8) and the limitations described in clause
(2) of the first paragraph of Section 5.01 and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes (“Covenant
Defeasance”). In the event of Legal Defeasance, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. In the event Covenant Defeasance occurs, the events described in clauses (2)(b), (3), (4), (5),
(6) and (8) of Section 6.01 will no longer constitute an Event of Default with respect to the Notes. If the Company exercises either its Legal Defeasance or Covenant Defeasance option, each Subsidiary Guarantor will be
released and relieved of any obligations under its Subsidiary Guarantee. 
 Section 9.02 Conditions to Legal Defeasance or Covenant
Defeasance. In order to exercise either Legal Defeasance or Covenant Defeasance: 
 (1) the Company must irrevocably
deposit with the Trustee, in trust, for the benefit of the Holders cash in United States dollars, non-callable United States government obligations, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, premium, if any, and interest on the Notes on the stated date for payment thereof or on the
applicable redemption date, as the case may be; 
 (2) in the case of Legal Defeasance, the Company shall have delivered 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 date of
this Indenture, there has been a change in the applicable federal income tax law, to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders 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; 

  
 91 

 (3) in the case of Covenant Defeasance, the Company shall have delivered to the
Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders 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, of which the Trustee is deemed to have notice, shall have occurred and be continuing on the
date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness or other borrowing of funds, or the grant of Liens securing such Indebtedness or other borrowing, all or a portion of which are to be
applied to such deposit); 
 (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of,
or constitute a default under the Indenture (other than a Default or Event of Default resulting from the incurrence of Indebtedness or other borrowing of funds, or the grant of Liens securing such Indebtedness or other borrowing, all or a portion of
which are to be applied to such deposit) or any other Indebtedness incurred under clause (2) of the definition of “Permitted Indebtedness”; 

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

(7) the Company shall have delivered to the Trustee an Officers’ Certificate stating that all conditions precedent
relating to such Legal Defeasance or Covenant Defeasance, as applicable, have been complied with; and 
 (8) the Company
shall have delivered to the Trustee an Opinion of Counsel (which opinion of counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent relating to such Legal Defeasance or Covenant
Defeasance, as applicable, have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Company. 

As used herein, “United States government obligation” means (x) any security which is (i) a direct
obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of
the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer
thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any United States government 

  
 92 

 
obligation which is specified in clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or
interest on any United States government obligation which is so specified and held; provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary
receipt from any amount received by the custodian in respect of the United States government obligation or the specific payment of principal or interest evidenced by such depositary receipt. 

Section 9.03 Application of Trust Money. 

(a) The Trustee or Paying Agent shall hold in trust all cash in United States dollars or non-callable
United States government obligations deposited with it pursuant to this Article 9 in respect of the Outstanding Notes, and shall apply the deposited cash in United States dollars and non-callable United
States government obligations in accordance with this Indenture to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent or any Subsidiary Guarantor or any Subsidiary or Affiliate of the
Company or any Subsidiary Guarantor 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 the principal of and the interest on the Notes, but money and United
States government obligations so held in trust need not be segregated from other funds except to the extent required by law. The Trustee shall be under no obligation to invest said funds, except as it may agree with the Company. 

(b) The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash in United
States dollars and non-callable United States government obligations deposited pursuant to Section 9.02, 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. 
 (c) Anything in this Article 9
to the contrary notwithstanding, the Trustee shall promptly deliver or pay to the Company from time to time upon the request of the Company any funds or United States government obligations held by it as provided in
Section 9.02 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 Section 9.04 Repayment to the
Company. Any cash in United States dollars or non-callable United States government obligations deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the
principal of or interest on the Notes and remaining unclaimed for two years after such principal or interest has become due and payable shall be repaid to the Company on its request or (if then held by the Company) will be discharged from such
trust; and the Holders will thereafter be permitted to look only to the Company (unless an applicable law designates another Person) for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust funds, 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 and written request of the Company cause
to be published once, in the New York Times and The 

  
 93 

 
Wall Street Journal (national edition), or mail to each Holder entitled to such funds, notice that such money remains unclaimed and that, after a date specified therein, which will not be less
than thirty (30) days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. 

Section 9.05 Reinstatement. If the Trustee or Paying Agent is unable to apply any funds in accordance with this Article 9
by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if the funds deposited with the Trustee to effect Covenant Defeasance
are insufficient to pay the principal of, and interest on, the Notes when due, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9
until such time as the Trustee or Paying Agent is permitted to apply all such funds in accordance with this Article 9; provided, however, that if the Company has made any payment of interest on, or principal of, any Notes
because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the funds held by the Trustee or Paying Agent. 

ARTICLE 10 
 PAYMENT OF
INTEREST 
 Section 10.01 Payment of Interest. The Company shall pay interest on the Notes at a rate of 8.75% per annum,
payable semi-annually in arrears on June 15 and December 15 of each year (each, an “Interest Payment Date”), commencing December 15, 2017. Interest shall be paid on each Interest Payment Date to the Holder of such
Note in whose name the Note is registered at 5:00 p.m. (New York City time) on June 1 or December 1 (whether or not a Business Day) (a “Regular Record Date”), as the case may be, next preceding the related Interest Payment
Date. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. In the event of the maturity, or purchase of a Note by the Company at
the option of the Holder, interest shall cease to accrue on such Note. Interest on the Notes shall accrue (except, in the case of Additional Notes, as otherwise specified in the Officers’ Certificate delivered pursuant to
Section 1.03 of this Indenture in respect thereof) from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance. 

Holders of Notes at 5:00 p.m. (New York City time) on a Regular Record Date shall receive payment of interest payable on the corresponding
Interest Payment Date. 
 Section 10.02 Defaulted Interest. Any installment of interest that is payable, but is not punctually
paid or duly provided for on any Interest Payment Date (“Defaulted Interest”) shall forthwith cease to be payable to the Holders in whose names the Notes were registered on the Regular Record Date applicable to such installment of
interest. The Company shall make payment of any Defaulted Interest (including any interest on such Defaulted Interest) to the Holders in whose names the Notes are registered at 5:00 p.m. (New York City time) on a special record date for the payment
of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid and the date of the proposed
payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the 

  
 94 

 
aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such
money when deposited to be held in trust for the benefit of the Holders entitled to such Defaulted Interest as provided in this Section 10.02. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest, which shall be not more than 15 calendar days and not less than ten calendar days prior to the date of the proposed payment and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be sent, by
first-class mail, postage prepaid, to each Holder at such Holder’s address as it appears in the registration books of the Registrar, not less than ten calendar days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Holders in whose names the Notes are registered at 5:00 p.m. (New York City time) on such Special Record Date. 

Section 10.03 Interest Rights Preserved. Subject to the foregoing provisions of this Article 10, each Note delivered under
this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. 

ARTICLE 11 
 SUBSIDIARY
GUARANTEES 
 Section 11.01 The Guarantee. Each Subsidiary Guarantor hereby jointly and severally guarantees (the
“Subsidiary Guarantee”), as a primary obligor and not as a surety, to the Trustee and each Holder and their respective successors and assigns, the prompt payment in full when due (whether at Stated Maturity, by required prepayment,
declaration, demand, by acceleration or otherwise) of the principal of and interest (including any interest, fees, costs or charges that would accrue but for the provisions of Title 11 of the United States Code after any bankruptcy or insolvency
petition under Title 11 of the United States Code) on the Notes, and all other obligations from time to time owing to the Trustee and the Holders by the Company under this Indenture and the Notes, in each case strictly in accordance with the terms
hereof (such obligations being herein collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor jointly and severally agrees that if the Company shall fail to pay in full when due (whether at stated maturity, by
acceleration or otherwise) any of the Guaranteed Obligations, each Subsidiary Guarantor will promptly pay the same in cash, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the
Guaranteed Obligations, the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal. 

Section 11.02 Obligations Unconditional. The obligations of the Subsidiary Guarantors under
Section 11.01 shall constitute a guaranty of payment and to the fullest extent permitted by applicable law, are absolute, irrevocable and unconditional, joint and several with each of the Subsidiary Guarantors, irrespective
of the value, genuineness, validity, regularity or

enforceability of the Guaranteed Obligations, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations, and irrespective of any other

more of the following shall not alter or impair the liability of a Subsidiary Guarantor hereunder, which shall remain absolute, irrevocable and unconditional under any and all circumstances as described above:

with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;

Guarantee, if any, or any other agreement or instrument referred to herein or therein, or against any other Person under any other guarantee of, or security for, any of the Guaranteed Obligations. Each Subsidiary Guarantor waives any and all notice

arising by reason of any performance by it of its guarantee in Section 11.01, whether by subrogation or otherwise, against the Company or any other Subsidiary Guarantor or any security for any of the Guaranteed Obligations.

 Section 11.05 Remedies. Each Subsidiary Guarantor jointly and severally agrees that, as between the Subsidiary Guarantor and
the Trustee or any Holder, the obligations of the Company under this Indenture and the Notes may be declared to be forthwith due and payable as provided in this Indenture (and shall be deemed to have become automatically due and payable in the
circumstances provided in this Indenture) for purposes of Section 11.01, notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and
payable) as against the Company and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by the Company) shall forthwith become due
and payable by the Subsidiary Guarantor for purposes of Section 11.01.

Payment of Money. Each Subsidiary Guarantor hereby acknowledges that the guarantee in this Subsidiary Guarantee constitutes an instrument for the payment of money, and consents and agrees that the Trustee or (if permitted by this Indenture) any
Holder shall have the right to bring a motion-action under New York CPLR Section 3213. 
 Section 11.07 Continuing
Guarantee. The guarantee in each Subsidiary Guarantee is a continuing guarantee of payment, and shall apply to all Guaranteed Obligations whenever arising. 

Section 11.08 General Limitation on Guarantee Obligations. In any action or proceeding involving any state corporate, limited
partnership or limited liability company law, or any applicable state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of the Subsidiary Guarantor under
Section 11.01 would otherwise be held or determined to be void, voidable, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under
Section 11.01, then, notwithstanding any other provision to the contrary, the amount of such liability shall, without any further action by the Subsidiary Guarantor, the Trustee or any Holder or any other person, be
automatically limited and reduced to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, without limitation, any borrowings or guarantees under any Credit 

  
 97 

 
Facility) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under
its Subsidiary Guarantee or pursuant to its contribution obligations under Section 11.09, will result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance
or fraudulent transfer under federal or state law. 
 Section 11.09 Right of Contribution. The Subsidiary Guarantor hereby
agrees that to the extent that any Subsidiary Guarantor shall have paid more than its proportionate share of any payment made under a Subsidiary Guarantee (based on the respective adjusted net assets of all Subsidiary Guarantors at the time of such
payment determined in accordance with GAAP), such Subsidiary Guarantor shall be entitled to seek and receive contribution from and against any other Subsidiary Guarantor which has not paid its proportionate share of such payment. Each Subsidiary
Guarantor’s right of contribution shall be subject to the terms and conditions of Section 11.04. The provisions of this Section 11.09 shall in no respect limit the obligations and liabilities
of any Subsidiary Guarantor to the Trustee or any Holder and the Subsidiary Guarantor shall remain liable to the Trustee or any Holder for the full amount guaranteed by the Subsidiary Guarantor hereunder.

result of payment under any guarantee of any such Indebtedness by any Subsidiary Guarantor); provided that a Subsidiary Guarantor shall not be permitted to be released from its Subsidiary Guarantee pursuant to this clause (3) if it is an
obligor with respect to Indebtedness that would not, under Section 4.06 be permitted to be incurred by a Restricted Subsidiary that is not a Guarantor; 

(4) upon Covenant Defeasance, Legal Defeasance or satisfaction and discharge of the Indenture with respect to the Notes as
provided pursuant to Article 7 or Article 9, as applicable; 
 (5) upon the liquidation or dissolution of such
Subsidiary Guarantor provided no Default or Event of Default has occurred or is continuing;

failure to act, or its own willful misconduct, except that

Officers’ Certificate or if such matter relates to a Guarantor, a Guarantor’s Officers’ Certificate of such Guarantor;

 114 

 (9) the Trustee shall not be liable for any action taken, suffered or omitted to
be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 

(10) the Trustee shall not be deemed to have notice of any default or Event of Default unless a Responsible Officer of the

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

 Without limiting any rights available to the Trustee under applicable law, when the
Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(6) or Section 6.01(7), the expenses (including the reasonable charges and expenses of
its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency or other similar law. 

The provisions of this Section shall survive the termination of this Indenture. 

Section 13.08 Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by the Trust Indenture Act,
the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to the Notes. 

Section 13.09 Corporate Trustee Required; Eligibility. There shall at all times be one (and only one) Trustee hereunder with
respect to the Notes. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least $50,000,000 and has its Corporate Trust Office in the continental United States
of America. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this 

  
 116 

 
Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

 Section 13.10 Resignation and Removal; Appointment of Successor. No resignation or removal of the Trustee and no appointment
of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 13.11. 

The Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee
required by Section 13.11 shall not have been delivered to the Trustee within 60 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, any court of competent
jurisdiction for the appointment of a successor Trustee. 
 The Trustee may be removed at any time by an Act of the Holders of a majority in
principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 13.11 shall not have been delivered to the Trustee within 30
days after the giving of a notice of removal pursuant to this paragraph, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee. 

If at any time: 

(1) the Trustee shall fail to comply with Section 13.08 after written request therefor by the Company
or by any Holder who has been a bona fide Holder of Notes for at least six months, or 
 (2) the Trustee shall cease to be
eligible under Section 13.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or 

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or
of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee, or (B) subject to
Section 6.11, any Holder who has been a bona fide Holder of Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee. 
 If the Trustee shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, shall promptly appoint a successor and shall comply with the applicable requirements of Section 13.11. If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed 

  
 117 

 
may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee. If, within one year after such resignation, removal or incapability,
or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 13.11, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 13.11, any Holder who has been a bona fide Holder of Notes for at least six months
may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders
in the manner provided in Section 2.07. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 

Section 13.11 Acceptance of Appointment by Successor. In case of the appointment hereunder of a successor Trustee, every such
successor Trustee so appointed shall execute, acknowledge and deliver to the Company, any Guarantor and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder. 
 In case of the appointment hereunder of a successor Trustee, the Company, any
Guarantor, the retiring Trustee and each successor Trustee shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary
or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee, and (2) shall add to or change any of the provisions of this Indenture as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Notes to which the appointment of such successor Trustee relates. 

  
 118 

 Upon request of any such successor Trustee, the Company and any Guarantor shall execute any and
all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible
under this Article. 
 Section 13.12 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the
Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. 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 with the same effect as if such successor Trustee had itself authenticated such Notes. 

Section 13.13 Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the
Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 

Section 13.14 Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent or Agents with respect to the
Notes which shall be authorized to act on behalf of the Trustee to authenticate the Notes issued upon original issue and upon exchange, registration of transfer, partial conversion or partial redemption or pursuant to
Section 1.07, and the Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in
this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent
so appointed and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent so appointed. An Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing
business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this

the Authenticating Agent or such successor corporation. 
 An Authenticating Agent may resign at any time by giving written notice thereof
to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such
a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent with respect to the Notes which shall be
acceptable to the Company and shall give notice of such appointment to all Holders in the manner provided in Section 2.07. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested
with all rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternate certificate of authentication in the following form:

If the Redemption Date is on a date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the
Company shall pay the related interest to a Holder on such Regular Record Date. 
  

	5.	Purchase at the Option of Holders 

 Pursuant to Section 4.13 of
the Indenture upon the occurrence of a Change of Control, each Holder will have the right to require that the Company purchase all or any portion of such Holder’s Notes pursuant to the offer described in Section 4.13
of the Indenture at a purchase price equal to 101% of the principal amount thereof, plus unpaid accrued interest, if any, thereon to the date of purchase (subject to the right of Holders of record on the relevant Regular Record Date to receive

of the Notes without prior notice to any Holder but with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes Outstanding and (ii) any Default or Event of Default may be waived by Notice to the
Trustee by the Holders of at least a majority in aggregate principal amount of the Notes Outstanding. In certain circumstances set forth in the Indenture, the Company and the Trustee may amend or supplement the Indenture or the Notes without the
consent of any Holder. 
  

	10.	Defaults and Remedies 

 If an Event of Default (other than an Event of Default specified
in Section 6.01(7) of the Indenture with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding may declare the principal of
and accrued but unpaid interest, if any, on all the Notes Outstanding to be immediately due and payable, except as provided in the Indenture. If an Event of Default specified in Section 6.01(7) of the Indenture occurs and
is continuing with respect to the Company, the principal of and accrued and unpaid interest, if any, on all the Notes then Outstanding, will, automatically and without any action by the Trustee or any Holder, become and be immediately due and
payable. Under certain circumstances, the Holders of a majority in aggregate principal amount of the Notes Outstanding may rescind any such declaration with respect to the Notes and its consequences. No reference herein to the Indenture or the
Indenture and no provision of this Note or of the Indenture or the Indenture shall impair, as among the Company and the Holder of the Notes, the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on
this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture prescribed.

Indenture Act, the Trustee under this Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

  

	12.	Indenture and Notes Solely Corporate Obligations 

 No recourse for the payment of the
principal of or interest on any Notes or for any claim based upon any Notes or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or in any supplemental indenture or in
any Notes or because of the creation of any indebtedness represented thereby shall be had against any incorporator, stockholder, member, manager, employee, agent, officer or director, as such, past, present or future, of the Company, the Subsidiary
Guarantors or any of the Company’s subsidiaries or of any successor thereto, either directly or through the Company, the Subsidiary Guarantors or any of the Company’s subsidiaries or any successor thereto, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the
execution of the Indenture and the issue of the Notes.
