 THIS SECOND SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated
as of July 2, 2012, is among OASIS PETROLEUM INC., a Delaware corporation (herein called the “Company”), having its principal office in First City Tower, 1001 Fannin, Suite 1500, Houston, Texas 77002, and OASIS PETROLEUM LLC, a
Delaware limited liability company, OASIS PETROLEUM NORTH AMERICA LLC, a Delaware limited liability company, OASIS PETROLEUM MARKETING LLC, a Delaware limited liability company, and OASIS PETROLEUM WELL SERVICES LLC, a Delaware limited liability
company (together, the “Subsidiary Guarantors”), and U.S. Bank National Association, as Trustee (herein called the “Trustee”) under the indenture, dated as of November 10, 2011, among the Company, the Subsidiary Guarantors
and the Trustee (the “Base Indenture” and, as amended and supplemented by this Supplemental Indenture in respect of the Notes, the “Indenture”). 
 RECITALS OF THE COMPANY AND THE SUBSIDIARY GUARANTORS 
 The Company and the
Subsidiary Guarantors have duly authorized, executed and delivered the Base Indenture to provide for the issuance from time to time of the Company’s unsecured debentures, notes or other evidences of indebtedness (herein called the
“Securities”), to be issued in one or more series, and the Guarantee by each of the Subsidiary Guarantors of the Securities, as the Base Indenture provides. 
 Section 901(7) of the Base Indenture provides, among other things, that the Company, the Subsidiary Guarantors and the Trustee may enter into indentures supplemental to the Base Indenture, without
the consent of any Holders of Securities (as defined in the Base Indenture), to establish the form or terms of any Security as permitted by Sections 201 and 301 of the Base Indenture. 

Pursuant to Sections 201 and 301 of the Base Indenture, the Company desires to execute this Supplemental Indenture to establish the form
and terms, and to provide for the issuance, of a series of senior notes designated as 6.875% Senior Notes due 2023 in an aggregate principal amount of $400,000,000 (the “Initial Notes”). 

From time to time subsequent to the Issue Date, the Company may, if permitted to do so pursuant to the terms of the Indenture, the
Initial Notes and the terms of its other indebtedness existing on such future date, issue additional senior notes of the same series as the Initial Notes in accordance with this Supplemental Indenture (the “Additional Notes” and, together
with the Initial Notes, the “Notes”), pursuant to this Supplemental Indenture. 
 The Company and the Subsidiary
Guarantors are members of the same consolidated group of companies. The Subsidiary Guarantors will derive direct and indirect economic benefit from the issuance of the Securities. Accordingly, each Subsidiary Guarantor has duly authorized the
execution and delivery of this Supplemental Indenture to provide for its full, unconditional and joint and several Guarantee of the Notes to the extent provided in or pursuant to the Indenture. 

This Supplemental Indenture is subject to the provisions of the Trust Indenture Act of 1939, as amended, that are required to be a part
of this Supplemental Indenture and shall, to the extent applicable, be governed by such provisions. 
 All things necessary have
been done to make the Notes, when executed by the Company and authenticated and delivered hereunder and duly issued by the Company, the valid obligations of the Company, and all things necessary have been done to make the Subsidiary Guarantees
thereof, when the Notes have been executed by the Company and authenticated and delivered hereunder and duly issued by the Company, the valid obligations of the Subsidiary Guarantors. All things necessary to make this Supplemental Indenture a valid
agreement of each of the Company and the Subsidiary Guarantors, in accordance with its terms, have been done. 

 NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE WITNESSETH: 

For and in consideration of the premises and the purchase of the Notes by the Holders thereof, it is mutually agreed, for the equal and
proportionate benefit of all Holders of the Notes, as follows:

commencement of the period for which the Fixed Charge Coverage Ratio is being calculated and on or prior to the date on which the event for which the calculation of the Fixed Charge Coverage Ratio is made (the “Calculation Date”), then the

pro forma effect as if they had occurred on the first day of the four-quarter reference period, and any Consolidated Cash Flow for such period will be calculated giving pro forma effect to any operating improvements or cost savings that have
occurred or are reasonably expected to occur in the reasonable judgment of the principal accounting officer or Chief Financial Officer of the Company (regardless of whether those operating improvements or cost savings could then be reflected in pro
forma financial statements prepared in accordance with Regulation S-X under the Securities Act or any other regulation or policy of the SEC related thereto);

interest, the interest expense on such Indebtedness will be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligation applicable to such Indebtedness,
but if the remaining term of such Hedging Obligation is less than 12 months, then such Hedging Obligation shall only be taken into account for that portion of the period equal to the remaining term thereof).

tenor signed (either physically or by means of a facsimile or an electronic transmission, provided that such electronic transmission is transmitted through the facilities of a Depositary) by such Holders in person or by agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company or the Subsidiary Guarantors.
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 the Indenture and conclusive in favor of the Trustee and the Company and, if applicable, the Subsidiary Guarantors, if made in the manner provided in this Section.

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.

notation of such action is made upon such Note.

the Holders of Outstanding Notes entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other Act provided or permitted by the Indenture to be given, made or taken by Holders of Notes, provided that
the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making 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 take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless 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 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 

  
 37 

 
shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the
requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, 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 Section 206. 
 The Trustee may set any day as a record date for the purpose of determining the Holders of Notes entitled to join in the giving or making of (1) any Notice of Default, (2) any declaration of
acceleration referred to in Section 602, (3) any request to institute proceedings referred to in Section 607(2) or (4) any direction referred to in Section 612. 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 join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless 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 cancelled and of no effect), and
nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is 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 in writing and to each Holder of Notes in the manner set forth in
Section 206. 
 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
each other party hereto in writing, and to each Holder of Notes in the manner set forth in Section 206, 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 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 take any action hereunder with regard to the Notes may do so with regard to all or any part of the principal amount of such Note or by one or
more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 

Section 205. Notices, Etc., to Trustee and Company. 
 Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by the Indenture to be made upon, given or furnished to, or filed

every purpose hereunder if made, given, furnished or filed in writing in the English language to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, or

 Section 206. Notice to Holders; Waiver. 
 Where the Indenture
provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing in the English language 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. If notice is mailed to Holders in the manner provided in this
Section 206, it is duly given, whether or not the addressee receives it. Where the 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. 
 Section 207. Conflict with Trust Indenture Act.

provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under the Trust Indenture Act to be a part of and govern the Indenture, the latter provision shall control. If any provision of the
Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to the Indenture as so modified or to be excluded, as the case may be.

out of or caused by, directly or indirectly, forces beyond its control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss

 Section 401. Title and Terms. 
 The Notes shall be entitled the
“6.875% Senior Notes due 2023.” The Trustee shall authenticate the Notes to be authenticated and delivered under this Supplemental Indenture on the Issue Date in an aggregate amount equal to $400,000,000, upon delivery of a Company Order.
The Trustee shall authenticate Additional Notes thereafter from time to time in unlimited amount for original issue upon receipt of a Company Order (subject to compliance with Section 1111). Any such Company Order shall also specify the date on
which the original issue of Notes is to be authenticated and, in relation to any Additional Notes, it shall also specify the principal amount thereof to be issued and shall certify that such issuance is not prohibited by Section 1111.

 The Notes will mature on January 15, 2023. Interest on the Notes will accrue at the rate of 6.875% per annum and
will be payable semiannually in cash on each January 15 and July 15, commencing on January 15, 2013 in the case of the Initial Notes, to the Persons who are registered Holders of Notes at the close of business on the
January 1and July 1 immediately preceding the applicable Interest Payment Date. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the date
of issuance to but excluding the actual Interest Payment Date. 
 The Notes shall be redeemable as provided in Article Twelve
and subject to Defeasance and Covenant Defeasance as provided in Article Fourteen. The Notes shall have such other terms as are indicated in Annex A. 
 Section 402. Denominations. 
 The Notes shall be issuable only
in fully registered form without coupons and only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. 

Section 403. Execution, Authentication, Delivery and Dating. 
 The Notes shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents. If its corporate seal is reproduced thereon,
it shall be attested by the Secretary or an Assistant Secretary of the Company. The signature of any of these officers on the Notes may be manual or facsimile. 

  
 42 

 If the Company elects to reproduce its corporate seal on the Notes, then such seal may be in
the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Notes. 
 Notes bearing
the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding the fact 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. 
 At any time and from time
to time after the execution and delivery of this Supplemental Indenture and as provided in Section 401, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Notes, and the Trustee in accordance with the Company Order shall authenticate and deliver such Notes. 
 Each Note shall be dated the date of its authentication. 
 No Note shall be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for in Annex A, signed manually in the name of the Trustee by
an authorized signatory, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been
authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Note to the Trustee for cancellation as provided in Section 409, for all purposes of the Indenture such Note shall be deemed
never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of the Indenture. 

Section 404. Temporary Securities. 
 Pending the preparation of definitive Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the
Officers executing such Notes may determine, as evidenced by their execution of such Notes. 
 If temporary Notes are issued,
the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or
agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor one or more definitive Notes of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under the Indenture as definitive
Notes. 
 Section 405. Registration, Registration of Transfer and Exchange. 

The Company shall cause to be kept at the office or agency of the Company in a Place of Payment required by Section 1102 a register
(the register maintained in such office or agency being herein sometimes referred to as the “Security Register”) in which, subject to such reasonable regulations 

  
 43 

 
as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Trustee is hereby appointed “Security Registrar” for the purpose of
registering Notes and transfers of Notes as herein provided, and its Corporate Trust Office is the initial office or agency where the Securities Register will be maintained. The Company may at any time replace such Security Registrar, change such
office or agency or act as its own Security Registrar; provided, however, that there shall be only one Security Register. The Company will give prompt written notice to the Trustee of any change of the Security Registrar or of the location of such
office or agency. 
 Upon surrender for registration of transfer of any Note at the office of the Security Registrar, Company
shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes, of any authorized denominations and of like tenor and aggregate principal amount. 

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company evidencing the same
debt, and entitled to the same benefits under the Indenture, as the Notes surrendered upon such registration of transfer or exchange. 
 Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or its attorney duly authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Notes, but the Company may require payment of a sum sufficient to cover any transfer tax or other governmental taxes and
fees that may be required by law or imposed by the Indenture in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 404, 1006, 1110, 1115 or 1208 not involving any transfer. 

If the Notes are to be redeemed in part, the Company shall not be required (1) to register the transfer of or exchange any Notes
during a period of 15 days before a selection of Notes for redemption under Section 1204, or (2) 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. 
 The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Notes:

 (1) Each Global Note authenticated under the Indenture shall be registered in the name of the Depositary
designated for such Global Note or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Note shall constitute a single Note for all purposes of the Indenture. 

(2) Notwithstanding any other provision in the Indenture, no Global Note may be exchanged in whole or in part for Notes
registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Note or a nominee thereof, unless (A) such Depositary (i) has notified the Company that
it is unwilling or unable to discharge its responsibilities properly as Depositary for such Global Note or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company has not appointed a qualified
successor within 90 days, (B) a Default or an Event of Default has occurred and is continuing and the Depositary has notified the Company and the Trustee of its decision to exchange such Global Note for Notes in certificated form or
(C) subject to the Depositary’s rules, the Company, at its option, has elected to terminate the book-entry system through the Depositary. 

  
 44 

 (3) Subject to clause (2) above, any exchange of a Global Note for
other Notes may be made in whole or in part, and all Notes issued in exchange for a Global Note or any portion thereof shall be registered in such names as the Depositary for such Global Note shall direct. 

(4) Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global
Note or any portion thereof, whether pursuant to this Section, Section 404, 406, 1006, 1110, 1115 or 1208 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Note, unless such Note is registered in the name
of a Person other than the Depositary for such Global Note or a nominee thereof. 
 The Depositary for a Global Note may
surrender such Global Note in exchange in whole or in part for Notes in definitive registered form on such terms as are acceptable to the Company, the Trustee and such Depositary. Thereupon, the Company and the Subsidiary Guarantors shall execute,
and the Trustee, upon receipt of a Company Order for the authentication and delivery of Notes in definitive registered form, shall authenticate and deliver, without service charge: 

(1) to the Person specified by such Depositary a new Note or Notes, with a notation of the Subsidiary Guarantee executed
by the Subsidiary Guarantors, of any authorized denominations as requested by such Person, in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Note; and 

(2) to such Depositary a new Global Note, with a notation of the Subsidiary Guarantee executed by the Subsidiary
Guarantors, in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Note and the aggregate principal amount of Notes authenticated and delivered pursuant to clause (1) above. 

Every Person who takes or holds any beneficial interest in a Global Note agrees that: 

(1) the Company, the Subsidiary Guarantors and the Trustee may deal with the Depositary as sole owner of the Global Note
and as the authorized representative of such Person; 
 (2) such Person’s rights in the Global Note shall be
exercised only through the Depositary and shall be limited to those rights established by law and agreement between such Person and the Depositary and/or direct and indirect participants of the Depositary; 

(3) the Depositary and its participants make book-entry transfers of beneficial ownership among, and receive and transmit
distributions of the principal of (and premium, if any) and interest on the Global Notes to, such Persons in accordance with their own procedures; and 
 (4) none of the Company, the Subsidiary Guarantors, the Trustee, nor any agent of any of them will have any responsibility or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 406. Mutilated, Destroyed, Lost and Stolen Notes. 
 If
any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

  
 45 

 If there shall be delivered to the Company and the Trustee (1) evidence to their
satisfaction of the destruction, loss or theft of any Note and (2) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee
that such Note has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen 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 stolen Note has become or is about
to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note. 
 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 stolen Note shall
constitute an original additional contractual obligation of the Company whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of the 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 stolen Notes. 
 Section 407. Payment of Interest; Interest Rights Preserved. 

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable
to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their
respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, 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 on each Note 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 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 Persons entitled to such Defaulted Interest as
in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than
10 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 given to each Holder of Notes in the manner set forth in Section 206, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such
Special Record Date and shall no longer be payable pursuant to the following clause (2). 

  
 46 

 (2) The Company may make payment of any Defaulted Interest on the Notes in
any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the
foregoing provisions of this Section, each Note delivered under the 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. 
 Section 408. Persons Deemed Owners. 

Prior to due presentment of a Note for registration of transfer, the Company, the Subsidiary Guarantors, the Trustee and any agent of the
Company, the Subsidiary Guarantors 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 Section 407) any
interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Subsidiary Guarantors, the Trustee nor any of their respective agents shall be affected by notice to the contrary.

 Section 409. Cancellation. 
 All Notes surrendered for payment, redemption, purchase, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly
cancelled 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 cancelled by the Trustee. No Notes shall be authenticated
in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by the Indenture. All cancelled Notes held by the Trustee shall be disposed of in accordance with the Trustee’s standard provisions or
as directed by a Company Order. 
 Section 410. Computation of Interest. 

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

Section 411. CUSIP or CINS Numbers. 
 The Company in issuing the Securities may use “CUSIP” or “CINS” numbers (if then generally in use, and in addition to the other identification numbers printed on the Securities), and,
if so, the Trustee shall use “CUSIP” or “CINS” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such
“CUSIP” or “CINS” numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such “CUSIP” or “CINS” numbers.

(other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 406 and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in

 and the Company or any Subsidiary
Guarantor in the case of (i), (ii) or (iii) of subclause (b) of this Section 501(1), has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust solely for such purpose cash in
Dollars, non-callable Government Securities, or a combination thereof in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on such Notes not theretofore delivered
to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Notes which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 

(2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such deposit or the grant of liens securing such borrowing); 
 (3) such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the Indenture) to which the Company or any Subsidiary

(ii) an Opinion of Counsel, stating that all conditions precedent set forth in clauses (3) and (5) above have been satisfied. 

Notwithstanding the satisfaction and discharge of the Indenture in respect of the Notes, the obligations of the Company to the Holders under Sections 405

pursuant to subclause (b) of clause (1) of this Section, the obligations of the Trustee under Section 502 and the last paragraph of Section 1103 shall survive. 
 Section 502. Application of Trust Money. 
 Subject to the
provisions of the last paragraph of Section 1103, all cash and Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 501 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 whose payment such cash and Government Securities (including the proceeds thereof) have been deposited with the Trustee. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 501 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, the Company’s and any Subsidiary Guarantor’s obligations under the Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 501; provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the

the case of a Reporting Failure) after receipt of a written notice (specifying such failure, requiring it to be remedied and stating that such notice is a “Notice of Default” under the Indenture) from the Trustee or the Holders of at least
25% in aggregate principal amount of the then Outstanding Notes to comply with any of the other agreements in the Indenture or the Notes; 
 (6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is Guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or any of its Restricted Subsidiaries, whether such Indebtedness or Guarantee now
exists, or is created after the Issue Date, which default: 
 (a) is caused by a failure to pay principal of, or
interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“Payment Default”); or 
 (b) results in the acceleration of such Indebtedness prior to its 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 $10.0 million or
more; 
 (7) failure by the Company or any Significant Subsidiary or any group of Restricted Subsidiaries that,
taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $10.0 million (net of any amounts
that a reputable and creditworthy insurance company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60 days; 

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

(9) the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest
audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law: 

  
 50 

 (a) commences a voluntary case; 

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

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

(d) generally is not paying its debts as they become due; or 

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

(a) is for relief against the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, in an involuntary case; or 

(b) appoints a custodian of the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, or for all or substantially all of the property of the Company, any Significant
Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary; or 

(c) orders the liquidation of the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 

Section 602. Acceleration of Maturity; Rescission and Annulment. 

In the case of an Event of Default specified in Section 601(9) or 601(10), all then Outstanding Notes will become due and payable
immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare all of the Notes to be due and
payable immediately by notice in writing to the Company and, in case of a notice by Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration. Upon any such declaration, the Notes shall become
due and payable immediately. 
 At any time after such a declaration of acceleration with respect to the Notes has been made,
the Holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 

(1) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction; 

(2) the Company has paid or deposited with the Trustee a sum sufficient to pay 

(a) all overdue interest on all the Notes, 

  
 51 

 (b) the principal of (and premium, if any, on) any Notes which have become
due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Notes, 
 (c) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor in such Notes, and 

(d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel; and 
 (3) all Events of Default with respect to the Notes,
other than the non-payment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 613. 

Notwithstanding the foregoing, if an Event of Default specified in Section 601(6) above shall have occurred and be continuing, such
Event of Default and any consequential acceleration (to the extent not in violation of any applicable law or in conflict with any judgment or decree of a court of competent jurisdiction) shall be automatically rescinded if (1) the Indebtedness
that is the subject of such Event of Default has been repaid or (2) if the default relating to such Indebtedness is waived by the holders of such Indebtedness or cured and if such Indebtedness has been accelerated, then the holders thereof have
rescinded their declaration of acceleration in respect of such Indebtedness, in each case within 20 days after the declaration of acceleration with respect thereto, and (3) any other existing Events of Default, except nonpayment of principal,
premium or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived. 

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

Section 603. Collection of Indebtedness and Suits for Enforcement by Trustee. 

If an Event of Default occurs and is continuing, the Trustee, in its own name and as trustee of an express trust, shall be entitled and
empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid or enforce the performance of any provision of the Notes or the Indenture, and may prosecute any such action or proceedings to
judgment or final decree, and may enforce any such judgment or final decree against the Subsidiary Guarantors or the Company or any other obligor upon the Notes (and collect in the manner provided by law out of the property of the Subsidiary
Guarantors or the Company or any other obligor upon the Notes wherever situated the moneys adjudged or decreed to be payable). 

Section 604. Trustee May File Proofs of Claim. 
 In case of any judicial proceeding relative to the Company, the Subsidiary Guarantors or any other obligor upon the Notes, or the property or creditors of the Company or the Subsidiary Guarantors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each Holder to make such 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 compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 707. 

  
 52 

 No provision of the Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 

Section 605. Trustee May Enforce Claims Without Possession of Notes. 

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

Section 606. Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of
principal or any premium or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee under Section 707; 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Notes,
ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal and any premium and interest, respectively; and 

THIRD: The remainder, if any, shall be paid to the Subsidiary Guarantors or the Company, as applicable, or to whomsoever
may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. 
 Section 607. Limitation on
Suits. 
 No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture,
or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless: 
 (1) such Holder
has previously given written notice to the Trustee of a continuing Event of Default with respect to the Notes; 

(2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 

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

  
 53 

 (5) the Holders of a majority in aggregate principal amount of the
Outstanding Notes have not waived such Event of Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period; 

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any
provision of the Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under the Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such Holders. 
 Section 608. Unconditional Right of
Holders to Receive Principal, Premium and Interest. 
 Notwithstanding any other provision in the Indenture, the Holder of
any Notes shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 407) interest on such Notes on the Stated Maturity expressed in such Notes (or, in the case of
redemption or offer by the Company to purchase the Notes pursuant to the terms of the Indenture, on the Redemption Date or purchase date, as applicable), and to institute suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder. 
 Section 609. Restoration of Rights and Remedies. 

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

Section 610. Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 406, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 611. Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be. 
 Section 612. Control by Holders. 
 Subject to Section 703(5), the Holders of a majority in aggregate principal amount of the Outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Notes, provided that 

  
 54 

 (1) the Trustee may refuse to follow any direction that conflicts with any
rule of law or with the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability, and 

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

 Section 613. Waiver of Past Defaults. 
 The Holders of a majority in aggregate principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past default hereunder and its consequences or compliance with any
covenant or provision hereof, except a default 
 (1) in the payment of the principal of or any premium or
interest on the Notes (including any Note which is required to have been purchased by the Company pursuant to an offer to purchase by the Company made pursuant to the terms of the Indenture), or 

(2) in respect of a covenant or provision hereof which under Article Ten cannot be modified or amended without the consent
of the Holder of each Outstanding Note affected. 
 Upon any such waiver with respect to a past default, such default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of the Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 614. Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party
litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. 
 Section 615. Waiver of Usury, Stay or Extension Laws. 
 Each of
the Company and the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension
law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of the Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such
law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 

  
 55 

 ARTICLE SEVEN 
 THE TRUSTEE 
 Section 701. Certain Duties and Responsibilities.

 The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing,
no implied covenants shall be read into the Indenture against the Trustee, and no provision of the Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of the Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

Section 702. Notice of Defaults. 
 Within 90 days after the occurrence of any Default with respect to the Notes, the Trustee shall transmit by mail to all Holders of Notes, as their names and addresses appear in the Security Register,
notice of such Default known to the Trustee, unless such Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of or any premium or interest with respect to any Note, the
Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default if the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Notes; and, provided, further, that
(1) in the case of any Default of the character specified in Section 601(4), no such notice to Holders shall be given until at least 30 days after the occurrence thereof, and (2) in the case of any Default of the character specified
in Section 601(5), no such notice to Holders shall be given until at least 60 days after the occurrence thereof. 

Section 703. Certain Rights of Trustee. 
 Subject to the provisions of Section 701: 
 (1) the Trustee
may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently
evidenced by a Board Resolution; 
 (3) whenever in the administration of the Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an
Officers’ Certificate; 
 (4) the Trustee may consult with counsel and the advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the
request or direction of any of the Holders pursuant to the Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction; 

  
 56 

 (6) the Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney; 
 (7) the Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it
hereunder; 
 (8) the Trustee may request that the Company and, if applicable, the Guarantors deliver an
Officers’ Certificate setting forth the names of individuals or titles of officers authorized at such time to take specified actions pursuant to the Indenture, which Officers’ Certificate may be signed by any person authorized to sign an
Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded; 
 (9) the Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Responsible Officer of the Trustee has received written notice of any event that
is in fact such a Default or Event of Default at the Corporate Trust Office of the Trustee, and such notice references the Notes and the Indenture; 
 (10) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred
upon it by the Indenture; 
 (11) the rights, privileges, protections, immunities and benefits given to the
Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act under the Indenture; and

 (12) anything in the Indenture notwithstanding, in no event shall the Trustee be liable for special, indirect,
punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Trustee has been advised as to the likelihood of such loss or damage and regardless of the form of action. 

Section 704. Not Responsible for Recitals or Issuance of Notes. 

The recitals contained herein and in the Notes, except the Trustee’s certificates of authentication, shall be taken as the statements
of the Company and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of the Indenture or of the Notes. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the Company of Notes or the proceeds thereof. 

  
 57 

 Section 705. May Hold Notes. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or
any other capacity, may become the owner or pledgee of Notes and, subject to Sections 708 and 713, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar
or such other agent. 
 Section 706. Money Held in Trust. 

Money and Government Securities held by the Trustee in trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
 Section 707. Compensation and Reimbursement. 
 The Company
agrees 
 (1) to pay to the Trustee from time to time compensation for all services rendered by it hereunder
(which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any
provision of the Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 

(3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without gross
negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder. When the Trustee incurs expenses or renders services after the occurrence of an Event of Default specified in paragraph (9) or (10) of Section 601, such expenses and
the compensation for such services are intended to constitute expenses of administration under any applicable Bankruptcy Law. 

The obligations of the Company and the Subsidiary Guarantors under this Section 707 shall survive the satisfaction and discharge of
the Indenture. 
 To secure the Company’s and the Subsidiary Guarantors’ payment obligations in this Section 707,
the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of the
Indenture. 
 “Trustee” for purposes of this Section shall include any predecessor Trustee; provided, however,
that the negligence or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

Section 708. Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act after a Default has occurred and is continuing, the Trustee shall either eliminate such interest
within 90 days, apply to the SEC for permission to continue as trustee or resign. 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 the Base
Indenture with respect to Securities of more than one series. 

  
 58 

 Section 709. 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, and has a combined capital and surplus of at least $50,000,000. 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 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 with respect to the Notes 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 710. 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 711. 

The Trustee may resign at any time with respect to the Notes by giving written notice thereof to the Company. If the instrument of
acceptance by a successor Trustee required by Section 711 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Notes. 
 The Trustee may be removed at any time by Act of the Holders of
a majority in aggregate principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. 
 If at any
time: 
 (1) the Trustee shall fail to comply with Section 708 after written request therefor by the Company
or by any Holder who has been a bona fide Holder of a Note for at least six months, or 
 (2) the Trustee shall
cease to be eligible under Section 709 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 614, any Holder who has been a bona fide Holder of a Note 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 with respect to all Notes and the appointment of a successor Trustee or Trustees. 

  
 59 

 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, with respect to the Notes, the Company, by a Board Resolution, shall within 60 days appoint a successor Trustee or Trustees with respect to the Notes and shall comply with the applicable requirements of
Section 711. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Notes shall be appointed by Act of the Holders of a majority in aggregate 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 711, become
the successor Trustee with respect to the Notes and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Notes shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 711, any Holder who has been a bona fide Holder of a Note 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 with respect to the Notes. 
 The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all Holders of Notes in the manner provided in Section 206. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

 Section 711. 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 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.

 Upon request of any such successor Trustee, the Company and the Subsidiary Guarantors 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 712. 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. 

  
 60 

 Section 713. 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 714. Appointment of Authenticating Agent. 
 The Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Notes issued upon original issue and upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 406, and Notes so authenticated shall be entitled to the benefits of the Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Supplemental 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 and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each 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 Section, the combined capital and surplus of such Authenticating Agent 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 an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 

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 which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in
Section 206 to all Holders of Notes with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the 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. 

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 707.

 If an appointment with respect to one or more series is made pursuant to this Section, the
Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

corporation), convert into another form of entity or continue in another jurisdiction; or (ii), directly or indirectly, sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or
more related transactions, to another Person, unless:

(4) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to

beginning of the applicable four-quarter period) either:

 For purposes of this Section 901, the sale, assignment, transfer, lease, conveyance or other disposition of all or
substantially all of the properties or assets of one or more Subsidiaries of the Company, which properties or assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties or assets of the
Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties or assets of the Company.

or any Securities or Securities Guarantee issued thereunder; 

  
 65 

 (14) add a corporate co-issuer in accordance with Section 901; or

 Upon the request of the Company, and upon receipt by the Trustee of the documents described in Section 1003, the Trustee
is hereby authorized to join with the Company and any Subsidiary Guarantor in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained and to accept the conveyance,
transfer, assignment, mortgage, charge or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such supplemental indenture that affects the Trustee’s own rights, duties or immunities under the Indenture or
otherwise. 
 Section 1002. Supplemental Indentures With Consent of Holders. 

The Company, the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture, the Securities Guarantees and the Securities
with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Securities of each series of Securities affected by such amendment or supplemental indenture, with each such series voting as a separate class (including,
without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities) and, subject to Section 608 and Section 613, any existing Default or Event of Default or compliance with any
provision of the Indenture, the Securities Guarantees or the Securities may be waived with respect to each series of Securities with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series
voting as a separate class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). 
 Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to
the Trustee of the consent of the Holders of Securities as aforesaid, and upon receipt by the Trustee of the documents described in Section 1003, the Trustee will join with the Company and the Subsidiary Guarantors in the execution of such
amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated
to, enter into such amended or supplemental Indenture. 
 It is not necessary for the consent of the Holders of Securities under
this Section 1002 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. 

After an amendment, supplement or waiver under this Section 1002 becomes effective, the Company will mail to the Holders of
Securities affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or
supplemental indenture or waiver. 

  
 66 

 Subject to Section 608 and Section 613, the application of or compliance with,
either generally or in any particular instance, any provision of the Indenture, the Securities or the Securities Guarantees may be waived as to each series of Securities by the Holders of a majority in aggregate principal amount of the Outstanding
Securities of such series. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 1002 may not (with respect to any Securities held by a non-consenting Holder): 

(1) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or
reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 602, or change any Place of Payment where, or the coin or currency in which, any Security or any premium or the interest thereon is payable, or impair the right to institute suit for the
enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date therefor); 
 (2) reduce the percentage in aggregate principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such amendment, supplement or waiver; 

(3) modify any of the provisions of Section 608 or Section 613, except to increase any such percentage or to
provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause (3) shall not be deemed to require the
consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of Section 711 and Section 1001(12);

 (4) waive a redemption payment with respect to any Security; provided, however, that any purchase or
repurchase of Securities shall not be deemed a redemption of the Securities; 
 (5) release any Subsidiary
Guarantor from any of its obligations under its Subsidiary Guarantee or the Indenture, except in accordance with the terms of the Indenture (as supplemented by any supplemental indenture); or 

(6) make any change in the foregoing amendment and waiver provisions. 

A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture that has expressly been included
solely for the benefit of one or more particular series of Securities, or that modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the
Indenture of the Holders of Securities of any other series. 
 Section 1003. Execution of Supplemental Indentures.

 In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the
modifications thereby of the trusts created by the Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officers’ Certificate and Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by the Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under the Indenture or
otherwise. 

  
 67 

 Section 1004. 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. 
 Section 1005. Conformity with Trust Indenture Act. 
 Every
supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act. 

Section 1006. Reference in Notes to Supplemental Indentures. 
 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 Company, to any such supplemental indenture may be prepared and executed by the
Company and such new Notes may be authenticated and delivered by the Trustee in exchange for Outstanding Notes. 
 Section 1007.
Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a
Security is a continuing consent by the Holder of a Security and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any
Security. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

ARTICLE ELEVEN 
 COVENANTS 
 Section 1101. Payment of Principal, Premium and Interest.

 The Company covenants and agrees for the benefit of the Notes that it will duly and punctually pay the principal of and any
premium and interest on the Notes in accordance with the terms of the Notes and the Indenture. Principal, premium, if any, and interest will be considered paid on the date due if a Paying Agent, if other than the Company or a Subsidiary thereof,
holds as of 11 a.m., New York City time, on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. 

The Company will pay interest (including post-petition interest in any proceeding under any applicable Bankruptcy Law) on overdue
principal and premium, if any, at the interest rate specified in the Notes to the extent lawful; and it will pay interest (including post-petition interest in any proceeding under any applicable Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent lawful. 
 Section 1102. Maintenance of Office or
Agency. 
 The Company will maintain, in the City and State of New York and in any other Place of Payment, an office or
agency where Notes may be presented or surrendered for payment, and it will maintain an office or agency in the United States where Notes may be surrendered for registration of 

  
 68 

 
transfer or exchange and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. The Company hereby
irrevocably designates as a Place of Payment for the Notes the City and State of New York, and initially appoints U.S. Bank National Association at its corporate trust office in the City of New York, which, at the date hereof, is located at 100 Wall
Street, Suite 1600, New York, New York 10005, as the Company’s office or agency in such city where the Notes may be presented or surrendered for payment. 
 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 in the City and State of New York, a Place of Payment for the Notes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

Section 1103. Money for Notes Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent, it will, before 11 a.m., New York City time, on 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. 
 Whenever the Company shall have one or more Paying Agents for
the Notes, it will, prior to 11 a.m., New York City time, on each due date of the principal of or any premium or interest on the Notes, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust
Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 The Company will cause each Paying Agent 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 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 the Notes 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 then held by the Company) shall be discharged from such trust;

  
 69 

 
and the Holder of such Notes shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect
to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that, if there are then outstanding any Notes not in global form, the Trustee or such Paying Agent, before being required to make any
such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the City and State 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. 

Section 1104. Annual Compliance Certificate; Statement by Officers as to Default. 

The Company and the Subsidiary Guarantors shall deliver to the Trustee within 150 days after the end of each fiscal year of the Company
ending after the Issue Date an Officers’ Certificate signed by the principal executive officer, the principal accounting officer or the principal financial officer of each of the Company and the Subsidiary Guarantors, stating that a review of
the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each of the Company and the Subsidiary Guarantors has
performed its obligations under the Indenture, and further stating whether or not the signers know of any Default or Event of Default that occurred during such period. If they do, the certificate shall describe such Default or Event of Default, its
status and what action the Company is taking or proposes to take with respect thereto. 
 The Company shall, so long as any Note
is Outstanding, deliver to the Trustee within five days after becoming aware of the occurrence of any Default or Event of Default, written notice (which need not be an Officers’ Certificate) setting forth the details of such Default or Event of
Default, and what action the Company is taking or proposing to take with respect thereto. 
 Section 1105. Existence.

 Subject to Article Nine, the Company will do or cause to be done all things necessary to preserve and keep in full force and
effect the existence, rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company. 
 Section 1106. Reports. 

Regardless of whether required by the rules and regulations of the SEC, so long as any Notes are Outstanding, the Company will file with
the SEC for public availability, within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing, in which case the Company will comply with the requirements described in the next following
paragraph of this Section 1106): 
 (1) all quarterly and annual reports that would be required to be filed
with the SEC on Forms 10-Q and 10-K under the Exchange Act if the Company were required to file such reports; and 
 (2) all current reports that would be required to be filed with the SEC on Form 8-K under the Exchange Act if the Company were required to file such reports. 

  
 70 

 All such reports will be prepared in all material respects in accordance with all of the rules and
regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Company’s consolidated financial statements by the Company’s certified independent accountants. 

If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company
will nevertheless continue filing the reports specified in the first paragraph of this Section 1106 with the SEC within the time periods specified in the first paragraph of this Section 1106 unless the SEC will not accept such a filing.
The Company will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred
to in the first paragraph of this Section 1106 on its website within the time periods that would apply if the Company were required to file those reports with the SEC. 
 If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraphs of this Section 1106 will
include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial
condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries. 
 Section 1107. Payment of Taxes. 
 The Company shall pay, and
shall cause each of its Subsidiaries to pay, prior to delinquency, any taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse
in any material respect to the Holders of the Notes. 
 Section 1108. [Reserved]. 

Section 1109. [Reserved]. 

Section 1110. Repurchase of Notes Upon a Change of Control. 
 If a Change of Control occurs, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that
Holder’s Notes pursuant to an offer (a “Change of Control Offer”) on the terms set forth in this Section 1110. In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control Payment”)
equal to not less than 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase (the “Change of Control Payment Date”), subject to the rights of
Holders of Notes on the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to
this Section 1110 and that all Notes tendered will be accepted for payment; 
 (2) the purchase price and
the Change of Control Payment Date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed; 
 (3) that any Note not tendered will continue to accrue interest; 

  
 71 

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

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of
business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that
such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are
being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount or an
integral multiple of $1,000 in excess of $2,000. 
 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 those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any
securities laws or regulations conflict with Section 1110, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 1110 by virtue of such compliance.

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

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or
portions of Notes properly tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes
properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The Paying Agent will promptly mail or wire transfer to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment
through the facilities of the Depositary), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if
any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date
unless the Company defaults in making the Change of Control Payment. 
 The Company will publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

  
 72 

 Notwithstanding anything to the contrary in this Section 1110, the Company will not be
required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the price, at the times and otherwise in compliance with the requirements set forth in this Section 1110
applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer. 
 A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at
the time of making the Change of Control Offer. Notes repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not Outstanding or will be retired and cancelled, at the Company’s option. Notes
purchased by a third party pursuant to the sixth paragraph of this Section 1110 will have the status of Notes issued and Outstanding. 
 In the event that Holders of at least 90% of the aggregate principal amount of the Outstanding Notes accept a Change of Control Offer and the Company (or any third party making such Change of Control
Offer, in lieu of the Company, as described in the sixth paragraph of this Section 1110) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not
more than 30 days following a Change of Control Payment Date, to redeem all, but not less than all, of the Notes that remain Outstanding at a Redemption Price equal to the Change of Control Payment plus, to the extent not included in the
Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain Outstanding, to the Redemption Date (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date).

 Section 1111. Incurrence of Indebtedness and Issuance of Preferred Stock. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly create, incur, issue, assume,
Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur;” with “incurrence” having a correlative meaning) any Indebtedness (including Acquired Debt), and the
Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) and issue Disqualified Stock, and
Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) and issue preferred stock, if (i) the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro
forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period and (ii) no Default would occur as a consequence of, and no Event of Default would be continuing following, the incurrence of the Indebtedness or the transactions relating to such incurrence, including any related
application of the proceeds thereof. 
 Notwithstanding the foregoing, the preceding paragraph of this Section 1111 will
not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any Disqualified Stock or preferred stock described in clauses (5) and (7) of this paragraph (collectively, “Permitted Debt”):

 (1) the incurrence by the Company and any Subsidiary Guarantor of Indebtedness under Credit Facilities in an
aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not
to exceed the greater of (a) $200.0 million and (b) the sum of $100.0 million plus an amount equal to 25.0% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness after
giving pro forma effect to such incurrence and the application of the proceeds therefrom; 

  
 73 

 (2) the incurrence by the Company and its Restricted Subsidiaries of
Existing Indebtedness; 
 (3) the incurrence by the Company of Indebtedness represented by the Notes to be issued
on the Issue Date; 
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation, improvement,
deployment, refurbishment or modification of property, plant or equipment or furniture, fixtures and equipment, in each case, used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount at any time
outstanding, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (4), not to exceed the
greater of (a) $15.0 million and (b) 2.0% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness; 

(5) the incurrence or issuance by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness
in exchange for, or the net proceeds of which are used to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company, or
Indebtedness (other than intercompany Indebtedness) or preferred stock of any Restricted Subsidiary, in each case that was permitted by the Indenture to be incurred or issued under the first paragraph of this Section 1111 or clause (2), (3),
(4), (10), (14) or (15) of this paragraph or this clause (5); 
 (6) the incurrence by the Company
or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (a) if the Company or any Subsidiary Guarantor is the obligor on such Indebtedness
and the payee is not the Company or a Subsidiary Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations then due with respect to the Notes, in the case of the Company, or the Subsidiary
Guarantee, in the case of a Subsidiary Guarantor; and (b)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and
(ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted
Subsidiary, as the case may be, that was not permitted by this clause (6); 
 (7) the issuance by any of the
Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any preferred stock; provided, however, that: 
 (a) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and 

(b) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted
Subsidiary, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (7); 

  
 74 

 (8) the incurrence of obligations of the Company or a Restricted Subsidiary
pursuant to Interest Rate and Currency Hedges, in each case entered into in the ordinary course of business for the non-speculative purpose of limiting risks that arise in the ordinary course of business of the Company and its Restricted
Subsidiaries; 
 (9) the Guarantee by the Company or any of the Subsidiary Guarantors of Indebtedness of the
Company or a Restricted Subsidiary that was permitted to be incurred by another provision of this Section 1111; provided that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall
be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed; 
 (10)
the incurrence by the Company or any Restricted Subsidiary of Permitted Acquisition Indebtedness; 
 (11) the
incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such
Indebtedness is covered within five Business Days; 
 (12) the incurrence by the Company or any Restricted
Subsidiary of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its Restricted Subsidiaries; 

(13) the incurrence by the Company or any Restricted Subsidiary of Indebtedness constituting reimbursement obligations
with respect to letters of credit; provided that, upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing; 

(14) the incurrence by any Foreign Subsidiary of Indebtedness that, in the aggregate together with all other Indebtedness
of all Foreign Subsidiaries (including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (14)), does
not exceed the greater of (a) 20.0% of the Adjusted Consolidated Net Tangible Assets of all Foreign Subsidiaries, considered as a consolidated enterprise, determined as of the date of the incurrence of such Indebtedness after giving pro
forma effect to such incurrence and the application of the proceeds therefrom and (b) $25.0 million; and 
 (15) the incurrence by the Company or any of the Subsidiary Guarantors of Indebtedness in an aggregate principal amount that, when taken together with all other Indebtedness of the Company and its
Restricted Subsidiaries outstanding on the date of such incurrence (other than Indebtedness permitted by clauses (1) through (14) above or the first paragraph of this Section 1111) and any Permitted Refinancing Indebtedness incurred
to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (15) does not exceed the greater of (a) 5.0% of Adjusted Consolidated Net Tangible Assets of
the Company, determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom and (b) $35.0 million. 

  
 75 

 The Company will not incur, and will not permit any Subsidiary Guarantor to incur, any
Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to
the Notes and the applicable Subsidiary Guarantee, on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by
virtue of being unsecured or by virtue of being secured on a first or junior Lien basis. 
 For purposes of determining
compliance with this Section 1111, (a) in the event that an item of proposed Indebtedness, Disqualified Stock or preferred stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through
(15) of the second paragraph of this Section 1111, or is entitled to be incurred or issued pursuant to the first paragraph of Section 1111, the Company will be permitted to divide and classify such item on the date of its incurrence
or issuance, or later divide and reclassify all or a portion of such item, in any manner that complies with this Section 1111 and (b) all Indebtedness outstanding on the Issue Date under the Senior Credit Agreement shall be deemed incurred
on the Issue Date under clause (1) of the second paragraph of this Section 1111. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional
Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock or preferred stock in the form of additional Disqualified Stock or
preferred stock of the same class will be deemed not to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock for purposes of this Section 1111; provided, in each such case, that the amount of any such
accrual, accretion or payment is included in Fixed Charges of the Company as accrued. 
 For purposes of determining compliance
with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect
on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign
currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction
shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 1111, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 1111 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount
of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in
which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 
 Section 1112.
Restricted Payments. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly: 
 (1) declare or pay any dividend or make any other payment or distribution on account of the
Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or
indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company and other
than dividends or distributions payable to the Company or any Restricted Subsidiary); 

  
 76

value any Subordinated Debt, except a payment of interest or principal at the Stated Maturity thereof (excluding (a) any intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries or (b) the purchase or
other acquisition of Subordinated Debt acquired in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such purchase or other acquisition); or 

(4) make any Restricted Investment; 
 (all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect
to such Restricted Payment: 
 (1) no Default or Event of Default has occurred and is continuing or would occur
as a consequence of such Restricted Payment; 
 (2) the Company would, at the time of such Restricted Payment and
after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage
Ratio test set forth in the first paragraph of Section 1111; and 
 (3) such Restricted Payment, together
with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries since the Prior Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8), (9) and
(12) of the next succeeding paragraph of this Section 1112), is equal to or less than the sum, without duplication, of: 
 (a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the most recent fiscal quarter commencing before the Prior Issue Date to the end
of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

 (b) 100% of (i)(A) the aggregate net cash proceeds and (B) the Fair Market Value of (x) marketable
securities (other than marketable securities of the Company or an Affiliate of the Company), (y) Capital Stock of a Person (other than the Company or an Affiliate of the Company) engaged primarily in any Related Business and (z) other

Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt 

  
 77 

 
securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the
Company), (ii) with respect to Indebtedness that is incurred on or after the Prior Issue Date, the amount by which such Indebtedness of the Company or any of its Restricted Subsidiaries is reduced on the Company’s consolidated balance
sheet upon the conversion or exchange after the Prior Issue Date of any such Indebtedness into or for Equity Interests of the Company (other than Disqualified Stock), and (iii) the aggregate net cash proceeds, if any, received by the Company or
any of its Restricted Subsidiaries upon any conversion or exchange described in clause (i) or (ii) above; plus 
 (c) with respect to Restricted Investments made by the Company and its Restricted Subsidiaries after the Prior Issue Date, an amount equal to the sum, without duplication, of (i) the net reduction in
such Restricted Investments in any Person resulting from (A) repayments of loans or advances, or other transfers of assets, in each case to the Company or any Restricted Subsidiary, (B) other repurchases, repayments or redemptions of such
Restricted Investments, (C) the sale of any such Restricted Investment to a purchaser other than the Company or a Subsidiary of the Company or (D) the release of any Guarantee (except to the extent any amounts are paid under such
Guarantee) that constituted a Restricted Investment plus (ii) with respect to any Unrestricted Subsidiary designated as such after the Prior Issue Date that is redesignated as a Restricted Subsidiary after the Prior Issue Date, the lesser of
(A) the Fair Market Value of the Company’s Investment in such Subsidiary held by the Company or any of its Restricted Subsidiaries at the time of such redesignation and (B) the aggregate amount of Investments made by the Company or
any of its Restricted Subsidiaries in such Subsidiary upon or after the designation of such Subsidiary as an Unrestricted Subsidiary and prior to the redesignation of such Subsidiary as a Restricted Subsidiary; plus 

(d) 100% of any dividends received by the Company or a Restricted Subsidiary after the Prior Issue Date from an
Unrestricted Subsidiary, to the extent such dividends were not otherwise included in the Consolidated Net Income of the Company for such period. 
 The preceding paragraph of this Section 1112 will not prohibit: 
 (1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at
the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of the Indenture; 
 (2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds from the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the

financed by loans from or Guaranteed by the Company or any of its Restricted Subsidiaries unless such loans have been repaid with cash on or prior to the date of determination) or from the substantially concurrent contribution of common equity
capital to the Company; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (3)(b) of the immediately preceding paragraph of this Section 1112 and
clause (7) of this paragraph of Section 1112; 

  
 78 

 (3) the purchase, redemption, defeasance or other acquisition or retirement
for value of Subordinated Debt (including the payment of any required premium and any fees and expenses incurred in connection with such purchase, redemption, defeasance or other acquisition or retirement) with the net cash proceeds from a
substantially concurrent incurrence of Permitted Refinancing Indebtedness; 
 (4) the purchase, redemption or
other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary held by any of the Company’s or any of its Restricted Subsidiaries’ current or former directors or employees in connection with
the exercise or vesting of any equity compensation (including, without limitation, stock options, restricted stock and phantom stock) in order to satisfy the Company’s or such Restricted Subsidiary’s tax withholding obligation with respect
to such exercise or vesting; 
 (5) purchases of Capital Stock deemed to occur upon the exercise of stock options
if such Capital Stock represents a portion of the exercise price thereof; 
 (6) payments to fund the purchase,
redemption or other acquisition or retirement for value by the Company of fractional Equity Interests arising out of stock dividends, splits or combinations, business combinations or other transactions permitted by the Indenture; 

(7) as long as no Default has occurred and is continuing or would be caused thereby, the purchase, redemption or other
acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary held by any of the Company’s or any of its Restricted Subsidiaries’ current or former directors or employees; provided that the
aggregate price paid for all such purchased, redeemed, acquired or retired Equity Interests may not exceed the sum of (a) $20.0 million, plus (b) the aggregate amount of cash proceeds received by the Company from the sale of the
Company’s Equity Interests (other than Disqualified Stock) to any such directors or employees that occurs after the Prior Issue Date; provided that the amount of such cash proceeds utilized for any such purchase, redemption or other acquisition
or retirement will be excluded from clause (3)(b) the immediately preceding paragraph of this Section 1112 and clause (2) of this paragraph plus (c) the cash proceeds of key man life insurance policies received by the Company and
its Restricted Subsidiaries after the Prior Issue Date; 
 (8) as long as no Default has occurred and is
continuing or would be caused thereby, the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any class or series of preferred stock of any Restricted

(9) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar
distribution) by a Restricted Subsidiary to the holders of Equity Interests (other than Disqualified Stock) of such Restricted Subsidiary; provided that such dividend or similar distribution is paid to all holders of such Equity Interests on a
pro rata basis based on their respective holdings of such Equity Interests; 
 (10) purchases of
Subordinated Debt at a purchase price not greater than (a) 101% of the principal amount of such Subordinated Debt and accrued and unpaid interest thereon in the event of a Change of Control or (b) 100% of the principal amount of such
Subordinated Debt and accrued and unpaid interest thereon in the event of an Asset Sale in connection with any change of control offer or asset sale offer required by the terms of such Subordinated Debt, but only if: 

  
 79 

 (a) in the case of a Change of Control, the Company has first complied with
and fully satisfied its obligations under Section 1110; or 
 (b) in the case of an Asset Sale, the Company
has complied with and fully satisfied its obligations under Section 1115;

(12) other Restricted Payments since the Prior Issue Date in an aggregate amount at any time outstanding not to exceed
$25.0 million. 
 The amount of all Restricted Payments (other than cash) shall be the Fair Market Value, on the date of such
Restricted Payment, of the Restricted Investment proposed to be made or the asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment,
except the Fair Market Value of any non-cash dividend made within 60 days after the date of declaration shall be determined as of such date. The Fair Market Value of any cash Restricted Payment shall be its face amount, and the Fair Market
Value of any non-cash Restricted Payment shall be determined in accordance with the definition of that term. For purposes of determining compliance with this Section 1112, in the event that a Restricted Payment meets the criteria of more than
one of the exceptions described in clauses (1) through (12) of the immediately preceding paragraph of this Section 1112 or is entitled to be made pursuant to the first paragraph of this Section 1112, 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 Section 1112. 

Section 1113. Limitation on Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or permit to exist any Lien (the “Initial Lien”), other than Permitted
Liens, upon any of its property or assets (including Capital Stock and Indebtedness of any Subsidiaries of the Company and including any income or profits from such property or assets), whether owned on the Issue Date or thereafter acquired, which
Lien secures any Subordinated Debt or other Indebtedness, unless: 
 (1) in the case of Liens securing
Subordinated Debt of the Company or a Subsidiary Guarantor, the Notes or Subsidiary Guarantee, as applicable, are secured by a Lien on such property or assets on a senior basis to the Subordinated Debt so secured with the same priority as the Notes
or such Subsidiary Guarantee, as applicable, has to such Subordinated Debt until such time as such Subordinated Debt is no longer so secured by a Lien; and 
 (2) in the case of Liens securing other Indebtedness of the Company or a Subsidiary Guarantor, the Notes or Subsidiary Guarantees, as applicable, are secured by a Lien on such property or assets on an
equal and ratable basis with the other Indebtedness so secured until such time as such other Indebtedness is no longer so secured by a Lien. 
 Any Lien securing the Notes or Subsidiary Guarantees created pursuant to the preceding paragraph of this Section 1113 shall provide by its terms that such Lien shall be automatically and
unconditionally released and discharged upon the unconditional release and discharge of the Initial Lien. 

  
 80 

 Section 1114. Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create 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 its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of its Restricted
Subsidiaries; 
 (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or 

(3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

 However, the preceding restrictions in the first paragraph of this Section 1114 will not apply to encumbrances or
restrictions existing under, by reason of or with respect to: 
 (1) the Senior Credit Agreement, any Existing
Indebtedness, Capital Stock or any other agreements or instruments, in each case, in effect on the Issue Date and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings
thereof; provided that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of the
Chief Executive Officer and the Chief Financial Officer of the Company, no more restrictive, taken as a whole, than those contained in the applicable agreements or instruments as in effect on the Issue Date; 

(2) the Indenture, the Notes and the Subsidiary Guarantees; 

(3) applicable law, rule, regulation, order, approval, permit or similar restriction; 

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted
Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or
refinancings thereof; provided, that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith
judgment of the Chief Executive Officer and the Chief Financial Officer of the Company, no more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of the Indenture to be incurred; 
 (5) customary non-assignment
provisions in contracts, leases and licenses (including, without limitation, licenses of intellectual property) entered into in the ordinary course of business;

(7) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such
Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 

(8) Liens permitted to be incurred under the provisions of Section 1113 that limit the right of the debtor to dispose
of the assets subject to such Liens; 
 (9) 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 1111 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); 
 (10) 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 1111; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less
favorable to the Company and its Restricted Subsidiaries, taken as a whole, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company, than the provisions contained in the Senior Credit Agreement
as in effect on the Issue Date; 
 (11) Indebtedness incurred or Capital Stock issued by any Restricted
Subsidiary, provided that the restrictions contained in the agreements or instruments governing such Indebtedness or Capital Stock (a) apply only in the event of a payment default or a default with respect to a financial covenant in such
agreement or instrument or (b) will not materially affect the Company’s ability to pay all principal, interest and premium, if any, on the Notes, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial
Officer of the Company; 
 (12) customary provisions restricting subletting or assignment of any lease governing

(including provisions forbidding subletting) in leases governing leasehold interests or Farm-In Agreements or Farm-Out Agreements relating to leasehold interests in oil and gas properties to the extent such provisions restrict the transfer of the
lease, the property leased thereunder or the other interests therein; 

  
 82 

 (b) 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, 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; and 

(c) Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments to the
extent such encumbrance or restriction restricts the transfer of the property (including Capital Stock) subject to such Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments. 

Section 1115. Asset Sales. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the 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 or Equity Interests issued or
sold or otherwise disposed of; and 
 (2) at least 75% of the aggregate consideration received in respect of such
Asset Sale by the Company or such Restricted Subsidiary (considered together on a cumulative basis, with all consideration received by the Company or any of its Restricted Subsidiaries in respect of other Asset Sales consummated since the Issue
Date), is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 
 (a) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities, Subordinated Debt and any
obligations in respect of preferred stock) that are assumed by the transferee of any such assets or Equity Interests pursuant to a customary novation agreement (or other legal documentation with the same effect) that includes a full release of the
Company or such Restricted Subsidiary from any and all liability therefor; 
 (b) any securities, notes or other
obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 90 days after the date of the Asset Sale, to the extent of the cash received
in that conversion; and 
 (c) any Capital Stock or assets of the kind referred to in clause (2) of the
third paragraph of this Section 1115. 
 Notwithstanding the foregoing, the 75% limitation referred to in clause (2)
of the first paragraph of this Section 1115 shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with clause (2) of the
first paragraph of this Section 1115 on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation. 

Within 365 days after the receipt of any Net Proceeds from an Asset Sale or, if the Company has entered into a binding commitment or
commitments with respect to any of the actions described in clauses 

  
 83 

 
(2) or (3) below, within the later of (a) 365 days after the receipt of any Net Proceeds from an Asset Sale or (b) 120 days after the entering into of such commitment or
commitments, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds: 
 (1) to permanently repay Senior Debt; 
 (2) to invest in Additional
Assets; or 
 (3) to make capital expenditures in respect of a Related Business of the Company or any of its
Restricted Subsidiaries. 
 However, pending application or investment of such Net Proceeds as provided in clauses (1)
through (3) of the immediately preceding paragraph, such Net Proceeds may be applied to temporarily reduce revolving credit Indebtedness. An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in
clauses (1) through (3) above will constitute “Excess Proceeds.” 
 Within ten Business Days after the
aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions
similar to those set forth in this Section 1115 with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be
purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain
after consummation of an Asset Sale Offer, the Company or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will use the Excess Proceeds to purchase the Notes and such other pari passu Indebtedness on a pro rata basis. Upon completion of each
Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 Notwithstanding the foregoing, the sale, conveyance or
other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by Sections 901 and/or 1110 of this Supplemental Indenture, as applicable, and not by
this Section 1115. 
 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 those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations
conflict with this Section 1115, or compliance with this Section 1115 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have
breached its obligations under this Section 1115 by virtue of such compliance. 
 In the event that, pursuant to this
Section 1115, the Company is required to commence an Asset Sale Offer, it will follow the procedures specified below: 
 (1) The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this
Section 1115. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the
“Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all 

  
 84 

 
Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount
has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 

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

 (3) Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the
Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

 (a) that the Asset Sale Offer is being made pursuant to this Section 1115 and the length of time the
Asset Sale Offer will remain open; 
 (b) the Offer Amount, the purchase price and the Purchase Date; 

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

(d) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer will cease to accrue interest after the Purchase Date; 
 (e) that Holders electing to have a Note
purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000 only; 

(f) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the
Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified
in the notice prior to the close of business on the third Business Day preceding the Purchase Date; 
 (g) that
Holders will be entitled to withdraw their election if the Company, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

(h) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by Holders
thereof exceeds the Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered
(with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess of $2,000, will be purchased); and 

  
 85 

 (i) that Holders whose Notes were purchased only in part will be issued new
Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000.

 (4) On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro
rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the
Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 1115. The Company, the depositary
or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such
Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset
Sale Offer on the Purchase Date. 
 Section 1116. Transactions with Affiliates. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any
Affiliate of the Company (each, an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction
is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of
the Company; and 
 (2) the Company delivers to the Trustee: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $15.0 million, a Board Resolution of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 1116 and
that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $30.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an accounting,
appraisal or investment banking firm of national standing. 
 The following items will not be deemed to be Affiliate
Transactions and, therefore, will not be subject to the provisions of the prior paragraph of this Section 1116: 

  
 86 

 (1) any employment, consulting or similar agreement or arrangement, stock
option or stock ownership plan, employee benefit plan, officer or director indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted
Subsidiaries in the ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto; 
 (2) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Subsidiary, an Equity Interest in, or
controls, such Person; 
 (4) reasonable fees and expenses and compensation paid to, and indemnity or insurance
provided on behalf of, officers, directors or employees of the Company or any of its Restricted Subsidiaries; 

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of a capital
contribution from, Affiliates of the Company; 
 (6) Restricted Payments that do not violate Section 1112 or
any Permitted Investments; 
 (7) loans or advances to employees in the ordinary course of business or consistent
with past practice; 
 (8) advances to or reimbursements of employees for moving, entertainment and travel
expenses, drawing accounts and similar expenditures in the ordinary course of business; 
 (9) the performance of
obligations of the Company or any of its Restricted Subsidiaries under the terms of any written agreement to which the Company or any of its Restricted Subsidiaries was a party on the Issue Date, as these agreements may be amended, modified or
supplemented from time to time; provided, however, that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not materially and adversely affect the rights of any
Holders of the Notes (as determined in good faith by the Board of Directors of the Company) as compared to the terms of the agreements in effect on the Issue Date; 

(10) (a) guarantees of performance by the Company and its Restricted Subsidiaries of Unrestricted Subsidiaries in the
ordinary course of business, except for Guarantees of Indebtedness in respect of borrowed money, and (b) pledges of Equity Interests of Unrestricted Subsidiaries for the benefit of lenders of Unrestricted Subsidiaries; 

(11) transactions between the Company or any Restricted Subsidiary and any Person, a director of which is also a director
of the Company or any direct or indirect parent company of the Company and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted Subsidiary; provided, however, that such director abstains from
voting as director of the Company or such direct or indirect parent company of the Company, as the case may be, on any matter involving such other Person; and 
 (12) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of the
Indenture, provided that in the reasonable determination of the Board of Directors of 

  
 87 

 
the Company or the senior management of the Company, such transactions are on terms not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could
reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company. 
 Section 1117. Subsidiary Guarantees. 
 If, after the Issue Date,
(1) any Material Domestic Subsidiary that is not already a Subsidiary Guarantor incurs any Indebtedness in excess of a De Minimis Amount, or issues any preferred stock or (2) any Domestic Restricted Subsidiary incurs any Indebtedness
whatsoever in respect of obligations under the Senior Credit Agreement, then such Subsidiary (referred to in clause (1) or (2) of this sentence) will become a Subsidiary Guarantor by executing and delivering a supplemental indenture,
substantially in the form provided for in Annex C of this Supplemental Indenture, to the Trustee within 30 days of the date on which it incurred such Indebtedness or issued such preferred stock (in each case, referred to in clause (1) or
(2) of this sentence). Such supplemental indenture shall be accompanied by an Opinion of Counsel to the Trustee to the effect that such supplemental indenture has been duly authorized, executed and delivered by that Restricted Subsidiary and
constitutes a valid and binding agreement of such Subsidiary, enforceable in accordance with its terms (subject to customary exceptions). 
 The Subsidiary Guarantee of a Subsidiary Guarantor will be released upon request of the Subsidiary Guarantor at such time as such Subsidiary Guarantor is not liable for any Indebtedness and has no
preferred stock outstanding, as long as at the time of such release (1) no Default or Event of Default has occurred and is continuing, (2) the Subsidiary Guarantor is not an obligor party to any undrawn Credit Facility or any Credit
Facility under which letters of credit are outstanding or any instrument governing the terms of undrawn Indebtedness or any Guarantee thereof and (3) the Subsidiary Guarantor has not been liable under any Indebtedness whatsoever during the
immediately preceding 181 consecutive days. 
 Section 1118. Designation of Restricted and Unrestricted Subsidiaries.

 The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that
designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary
designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation. That designation will only be permitted if the applicable Restricted Subsidiary meets the definition of an Unrestricted Subsidiary
and if such Investment would be permitted at that time, either pursuant to (1) Section 1112 or (2) the definition of Permitted Investment. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a Board Resolution of the Company giving effect
to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 1112. If, at any time, any Unrestricted Subsidiary would fail to meet the requirements of
the definition of “Unrestricted Subsidiary” set forth in Section 201 of this Supplemental Indenture, it will thereafter cease to be an Unrestricted Subsidiary for purposes of the Indenture and any Indebtedness of such Subsidiary will
be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 1111, the Company will be in Default of the covenant in Section 1111. 

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that
such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted
under Section 1111, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

  
 88 

 Section 1119. Termination of Certain Covenants. 

From and after the occurrence of an Investment Grade Rating Event, the Company and its Restricted Subsidiaries shall no longer be subject
to clause (4) of Section 901 and Sections 1111, 1112, 1114, 1115 and 1116 of this Supplemental Indenture. Furthermore, after an Investment Grade Rating Event, the Company may not designate any of its Subsidiaries as Unrestricted
Subsidiaries. 
 ARTICLE TWELVE 
 REDEMPTION OF NOTES 
 Section 1201. Applicability of Article.

 The Notes shall be redeemable at the election of the Company in accordance with their terms and in accordance with this
Article Twelve. 
 Section 1202. Election to Redeem; Notice to Trustee. 

In case of any redemption of less than all Notes, the Company shall, at least five Business Days prior to the giving of notice of such
redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of the Redemption Date and of the principal amount of Notes to be redeemed. In the case of any redemption of Notes (1) prior to the expiration of any
restriction on such redemption provided in the terms of the Notes or elsewhere in the Indenture or (2) pursuant to an election of the Company that is subject to a condition specified in the terms of the Notes or elsewhere in the Indenture, the
Company shall furnish the Trustee, prior to giving notice of such redemption, with an Officers’ Certificate evidencing compliance with such restriction or condition. 
 Section 1203. Optional Redemption. 
 At its option, the Company
may redeem the Notes, in whole or in part, in principal amounts of $2,000 or any integral multiple of $1,000 in excess thereof, at any time or from time to time, at the applicable Redemption Prices determined as set forth in the form of Note
attached as Annex A hereto, in accordance with the terms set forth in the Notes, and in accordance with this Article Twelve. 

Section 1204. Selection by Trustee of Notes to Be Redeemed. 
 If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes to be redeemed among the Holders of the Notes on a pro rata basis (or, in the case of Global Notes,
the Trustee will select the Notes for redemption based on DTC’s method that most nearly approximates a pro rata selection), unless otherwise required by law or applicable securities exchange requirements. 

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for
partial redemption, the principal amount at maturity thereof to be redeemed. No Notes in amounts of $2,000 or less shall be redeemed in part. Notes and portions of Notes selected shall be in amounts of $2,000 and integral multiples of $1,000 in
excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire Outstanding amount of Notes held by such Holder, even if less than $2,000 and/or a non-multiple of $1,000, shall be redeemed. Except as provided in the
preceding sentence, provisions of the Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

  
 89 

 Section 1205. Notice of Redemption. 

Subject to the final paragraph of this Section 1205, at least 30 days but not more than 60 days before a Redemption Date, the Company
shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address; provided, however, that (notwithstanding the foregoing) notices of redemption may be mailed more
than 60 days prior to a Redemption Date if such notice is issued in connection with a Defeasance or Covenant Defeasance of the Notes or the satisfaction and discharge of this Indenture. 

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

(1) the Redemption Date; 
 (2) the Redemption Price, or if not then ascertainable, the manner of calculation thereof; 
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal
amount equal to the unredeemed portion of the original Note shall be issued in the name of the Holder thereof upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
 (5) that Notes
called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and become due on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived; 

(6) that, unless the Company defaults in making such redemption payment, interest, if any, on Notes called for redemption
ceases to accrue on and after the Redemption Date; 
 (7) the paragraph of the Notes and/or Section of this
Supplemental Indenture pursuant to which the Notes called for redemption are being redeemed; 
 (8) that no
representation is made as to the correctness or accuracy of the CUSIP or CINS number, if any, listed in such notice or printed on the Notes; and 
 (9) any conditions that must be satisfied prior to the Company becoming obligated to consummate such redemption. 
 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, however, that the Company shall have delivered to the
Trustee, at least five Business Days prior to mailing of notice of the redemption (or such shorter period of time as may be acceptable to the Trustee), a Company Request that the Trustee give such notice and setting forth the information to be
stated in such notice as provided in the preceding paragraph. 
 Notwithstanding the preceding provisions of this
Section 1205, notice of any redemption upon an Equity Offering may be given prior to the completion of the related Equity Offering, and any such redemption or notice may at the Company’s discretion, be subject to one or more conditions
precedent, including, but not limited to completion of the related Equity Offering. 

  
 90 

 Section 1206. Deposit of Redemption Price. 

Prior to 11:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1103) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Notes which are to be redeemed on that date. 
 Section 1207. Notes Payable on Redemption Date.

 Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Notes shall cease to bear interest. Upon surrender of any such Notes
for redemption in accordance with said notice, such Notes shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or
prior to the Redemption Date will be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant record dates according to their terms and the provisions of Section 407.

 If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium
shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Note. 
 Section 1208. Notes
Redeemed in Part. 
 Any Note which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with,
if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing), and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and
in exchange for the unredeemed portion of the principal of the Note so surrendered.

Section 1401. Company’s Option to Effect Defeasance or Covenant Defeasance. 

The Company may elect, at its option at any time, to have Section 1402 or Section 1403 applied to the Notes, upon compliance
with the conditions set forth below in this Article. Any such election shall be evidenced in a Board Resolution set forth in an Officers’ Certificate delivered to the Trustee. 
 Section 1402. Defeasance and Discharge. 
 Upon the
Company’s exercise of its option to have this Section applied to the Notes, the Company shall be deemed to have been discharged from its obligations with respect to such Notes as provided in this Section on and after the date the conditions set
forth in Section 1404 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be 

  
 91 

 
deemed to have paid and discharged the entire indebtedness represented by such Notes and to have satisfied all its other obligations under such Notes and the Indenture insofar as the Notes are
concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following, which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of
such Notes to receive, solely from the trust fund described in Section 1404 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Notes when payments are due; (2) the
Company’s obligations with respect to such Notes under Sections 404, 405, 406, 1102 and 1103 and its obligations under Section 314(a) of the Trust Indenture Act; (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and the Company’s and the Subsidiary Guarantors’ obligations in connection therewith; and (4) this Article. If the Company exercises its defeasance option pursuant to this Section 1402, the Subsidiary Guarantees will
terminate with respect to the Notes, and payment of the Notes may not be accelerated pursuant to Section 602 because of an Event of Default. Subject to compliance with this Article, the Company may exercise its option to have this Section
applied to any Notes notwithstanding the prior exercise of its option to have Section 1403 applied to such Notes. 

Section 1403. Covenant Defeasance. 
 Upon the Company’s exercise of its option to have this Section applied to the Notes, (1) the Company shall be released from its obligations under Section 901(4), Section 1106, Sections
1110 through 1118, inclusive; (2) the occurrence of any event specified in Sections 601(3) (with respect only to the obligation under Section 901(4)), 601(4), 601(5), 601(6), 601(7), 601(9) (with respect only to Significant Subsidiaries)
or 601(10) (with respect only to Significant Subsidiaries), shall be deemed not to be or to result in an Event of Default and (3) the Subsidiary Guarantees shall be automatically released, in each case with respect to such Notes as provided in
this Section on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Notes, the Company may
omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article
or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of the Indenture and such Notes shall be unaffected thereby. 

Section 1404. Conditions to Defeasance or Covenant Defeasance. 

The following shall be the conditions to the application of Section 1402 or Section 1403 to any Notes: 

(1) the Company must irrevocably deposit with the Trustee (or another trustee that satisfies the requirements of
Section 709 and agrees to comply with the provisions of this Article Fourteen applicable to it), in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and
non-callable Government Securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, nationally recognized appraisal firm, or nationally recognized firm of independent public accountants to pay the
principal of, or interest and premium, if any, on the Outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated
date for payment or to a particular Redemption Date; 
 (2) in the case of an election under Section 1402
hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming that: 

  
 92 

 (a) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling; or 
 (b) since the Issue Date, there has been a change in the applicable U.S.
federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the
Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the
case if such Defeasance had not occurred; 
 (3) in the case of an election under Section 1403 hereof, the
Company must deliver to the Trustee an Opinion of Counsel confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax
on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit
or the grant of Liens securing such borrowing); 
 (5) such Defeasance or Covenant Defeasance and the related
deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that
the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; 

(7) the Company must deliver to the Trustee an Officers’ Certificate, stating that all conditions precedent set forth
in clauses (1) through (6) of this Section 1404 have been complied with; and 
 (8) the Company
must deliver to the Trustee an Opinion of Counsel, stating that all conditions precedent set forth in clauses (2), (3) and (5) of this Section 1404 have been complied with. 
 Section 1405. Deposited Money and Government Securities to Be Held in Trust; Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 1103, all money and Government Securities (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely
for purposes of this Section and Section 1406, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 1404 in respect of any Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such
Notes, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law. 

  
 93 

 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the Government Securities deposited pursuant to Section 1404 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
Outstanding Notes. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company
from time to time upon Company Request any money or Government Securities held by it as provided in Section 1404 with respect to any Notes which, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 1404(1)), are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance,
as the case may be, with respect to such Notes. 
 Section 1406. Reinstatement. 

If the Trustee or any Paying Agent is unable to apply any money in accordance with this Article with respect to any Notes by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under the Indenture and such Notes from which the Company has been discharged or released pursuant to
Section 1402 or 1403 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Notes, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to
Section 1405 with respect to such Notes in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Note following such reinstatement of its obligations, the
Company shall be subrogated to the rights (if any) of the Holders of such Notes to receive such payment from the money so held in trust.

 [INTENTIONALLY DELETED] 

ARTICLE SIXTEEN 
 SUBSIDIARY GUARANTEES 
 Section 1601. Unconditional Guarantee.

 For value received, each of the Subsidiary Guarantors hereby fully and unconditionally guarantees (the “Subsidiary
Guarantee”) to the Holders and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on the Notes and all other amounts due and payable under the Indenture and the Notes by the Company (collectively,
the “Obligations”), when and as such principal, premium, if any, and interest shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, according to the terms of the
Notes and the Indenture, subject to the limitations set forth in Section 1603. 
 Failing payment when due of any amount
guaranteed pursuant to its Subsidiary Guarantee, for whatever reason, each of the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantee hereunder is intended to be a general, unsecured,
senior obligation of each of the Subsidiary Guarantors and will rank pari passu in right of payment with all debt of such Subsidiary Guarantor that is not, by its terms, expressly subordinated in right of payment to the Subsidiary Guarantee.
Each of the Subsidiary Guarantors hereby agrees that its obligations hereunder shall be full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Notes, the Subsidiary Guarantee of any other Subsidiary
Guarantor or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company or any other Subsidiary

  
 94 

 
Guarantor, or any action to enforce the same or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of the Subsidiary Guarantors. Each of the
Subsidiary Guarantors hereby agrees that in the event of a default in payment of the principal of, or premium, if any, or interest on the Notes, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise,
legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to Section 607, by the Holders, on the terms and conditions set forth in the Indenture, directly against such Subsidiary Guarantor to enforce its Subsidiary
Guarantee without first proceeding against the Company or any other Subsidiary Guarantor. 
 The obligations of each of the
Subsidiary Guarantors under this Article shall be as aforesaid full and unconditional and shall not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (1) any compromise,
settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Company or any of the other Subsidiary Guarantors contained in the Notes or the Indenture, (2) any
impairment, modification, release or limitation of the liability of the Company, any of the other Subsidiary Guarantors or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or
future provision of any applicable bankruptcy law, or other statute or from the decision of any court, (3) the assertion or exercise by the Company, any of the other Subsidiary Guarantors or the Trustee of any rights or remedies under the Notes
or the Indenture or their delay in or failure to assert or exercise any such rights or remedies, (4) the assignment or the purported assignment of any property as security for the Notes, including all or any part of the rights of the Company or
any of the other Subsidiary Guarantors under the Indenture, (5) the extension of the time for payment by the Company or any of the other Subsidiary Guarantors of any payments or other sums or any part thereof owing or payable under any of the
terms and provisions of the Notes or the Indenture or of the time for performance by the Company or any of the other Subsidiary Guarantors of any other obligations under or arising out of any such terms and provisions or the extension or the renewal
of any thereof, (6) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or any of the other Subsidiary Guarantors set forth in the Indenture, (7) the voluntary or involuntary
liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of, or other similar proceeding affecting, the Company or any of the other Subsidiary Guarantors or any of their respective assets, or the disaffirmance of the Notes, the Subsidiary Guarantee or the Indenture in any such
proceeding, (8) the release or discharge of the Company or any of the other Subsidiary Guarantors from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law,
(9) the unenforceability of the Notes or the Indenture or (10) any other circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the Subsidiary Guarantees) which might otherwise constitute a legal or
equitable discharge of a surety or guarantor. 
 Each of the Subsidiary Guarantors hereby (1) waives diligence,
presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or any of the Subsidiary Guarantors, and all demands whatsoever, (2) acknowledges that any agreement, instrument
or document evidencing its Subsidiary Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Subsidiary Guarantee without notice to it and
(3) covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Subsidiary Guarantee. Each of the Subsidiary Guarantors further agrees that if at any time all or any part of any payment theretofore
applied by any Person to its Subsidiary Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of the Company or any of the Subsidiary Guarantors, the
Subsidiary Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Subsidiary Guarantee shall continue to be effective or be reinstated,
as the case may be, as though such application had not been made. 

  
 95 

 Each of the Subsidiary Guarantors shall be subrogated to all rights of the Holders and the
Trustee against the Company in respect of any amounts paid by such Subsidiary Guarantor pursuant to the provisions of the Indenture, provided, however, that such Subsidiary Guarantor, shall not be entitled to enforce or to receive any payments
arising out of, or based upon, such right of subrogation until all of the Notes and the Subsidiary Guarantees shall have been paid in full or discharged. 
 Section 1602. Execution and Delivery of Notation of Subsidiary Guarantee. 
 To further evidence its Subsidiary Guarantee set forth in Section 1601, each of the Subsidiary Guarantors hereby agrees that a notation relating to such Subsidiary Guarantee, substantially in the
form attached hereto as Annex B, shall be endorsed on each Note entitled to the benefits of the Subsidiary Guarantee authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an Officer of such Subsidiary
Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, an Officer of the general partner of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that the Subsidiary Guarantee set forth in
Section 1601 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation relating to its Subsidiary Guarantee. If any Officer of the Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is
a limited partnership, any Officer of the general partner of the Subsidiary Guarantor, whose signature is on the Indenture or a Note no longer holds that office at the time the Trustee authenticates such Note or at any time thereafter, the
Subsidiary Guarantee of such Note shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantees set forth in the Indenture on behalf of
the Subsidiary Guarantors. 
 Section 1603. Limitation on Subsidiary Guarantors’ Liability. 

Each Subsidiary Guarantor and by its acceptance hereof each Holder of a Note entitled to the benefits of the Subsidiary Guarantee hereby
confirm that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Federal or State law. To effectuate the
foregoing intention, the Holders of a Note entitled to the benefits of the Subsidiary Guarantees and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary Guarantor under its Subsidiary Guarantee shall be limited
to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and 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, result in the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or
State law. 
 Section 1604. Release of Subsidiary Guarantors from Guarantee. 

Each Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee as set forth in the second
paragraph of Section 1117, and the Subsidiary Guarantee of a Subsidiary Guarantor will also be released immediately: 
 (1) upon any sale or other disposition of all or substantially all of the properties or assets of such Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either
before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate Section 1115; 

  
 96 

 (2) upon any sale or other disposition of the Capital Stock of such
Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate Section 1115 and such Subsidiary Guarantor no
longer qualifies as a Subsidiary of the Company as a result of such disposition; 
 (3) upon designation of such
Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with Section 1118; 
 (4) upon Defeasance
or Covenant Defeasance in accordance with Article Fourteen or satisfaction and discharge of the Indenture in accordance with Article Five; or 
 (5) upon the liquidation or dissolution of such Subsidiary Guarantor, provided that no Default or Event of Default occurs as a result thereof or shall have occurred and is continuing. 

The Trustee shall deliver an appropriate instrument evidencing any release of a Subsidiary Guarantor from the Subsidiary Guarantee upon
receipt of a Company Request accompanied by an Officers’ Certificate and an Opinion of Counsel the Subsidiary Guarantor is entitled to such release in accordance with the provisions of the Indenture. 

Any Subsidiary Guarantor not released in accordance with the provisions of the Indenture will remain liable for the full amount of
principal of (and premium, if any, on) and interest on the Notes as provided in this Article Sixteen, subject to the limitations of Section 1603. 
 Section 1605. Subsidiary Guarantor Contribution. 
 In order to
provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors hereby agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under
its Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the net assets of each Subsidiary Guarantor (including the Funding Guarantor) for
all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s Obligations with respect to the Notes or any other Subsidiary Guarantor’s obligations with respect to its Subsidiary Guarantee. 

Section 1606. Subsidiary Guarantors May Consolidate, etc., on Certain Terms. 

A Subsidiary Guarantor may not sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with
or merge with or into (regardless of whether such Subsidiary Guarantor is the surviving Person) another Person, other than the Company or another Subsidiary Guarantor, unless: 

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and 

(2) either: 
 (a) (i) such Subsidiary Guarantor is the surviving Person or (ii) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any
such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under the Indenture (including its Subsidiary Guarantee), on the terms set forth herein, pursuant to a supplemental
indenture satisfactory to the Trustee; or 

  
 97 

 (b) such transaction does not violate the provisions of Section 1115.

 In case of any such consolidation, merger, sale or other disposition and upon the assumption by the successor Person, by
supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee of such Subsidiary Guarantor and the due and punctual performance of all of the covenants and conditions of the
Indenture to be performed by the Subsidiary Guarantor, such successor Person will succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such successor Person
thereupon may cause to be signed any or all of the Subsidiary Guarantee notations to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by such Subsidiary Guarantor and delivered to the Trustee. All the
Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under the Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all of such
Subsidiary Guarantees had been issued at the date of the execution hereof. 
  

 
 The Trustee
hereby accepts the trusts in the Indenture upon the terms and conditions herein set forth.

 [Form of Reverse of Note] 

6.875% Senior Note due 2023 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. To the extent that any of the terms and provisions of this Note conflict
with the express provisions of the Indenture, the terms and provisions of the Indenture shall govern and be controlling. 
 (1)
INTEREST. Interest on the Notes will accrue at the rate of 6.875% per annum and will be payable semi-annually in arrears on January 15 and July 15, beginning on January 15, 2013. Interest on the Notes will accrue from the
date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If a payment date is a Legal Holiday at a Place of
Payment, payment may be made at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue on such payment for the intervening period. The Company will pay interest (including post-petition interest in any
proceeding under any applicable Bankruptcy Law) on overdue principal and premium, if any, at the interest rate specified in the Notes to the extent lawful; and it will pay interest (including post-petition interest in any proceeding under any
applicable Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. 
 (2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the January 1 or
July1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 407 of the Indenture with respect to Defaulted Interest. Holders
must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, due at Maturity. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such
purpose in the City and State of New York, which, at the Issue Date, is the office of the Trustee located at 100 Wall Street, Suite 1600, New York, New York 10005, or, at the option of the Company, payment of interest may be made by check mailed to
the Holders at their addresses set forth in the Security Register; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all
other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts. 
 (3) PAYING AGENT AND SECURITY REGISTRAR. Initially, U.S. Bank National Association, the
Trustee under the Indenture, will act as Paying Agent and Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to any Holder. The Company may act in any such capacity. 

(4) INDENTURE. The Notes are a series of Securities issued by the Company under an Indenture, dated as of November 10, 2011,
by and among the Company, the Subsidiary Guarantors parties thereto and the Trustee (the “Original Indenture”), as amended and supplemented by the Second Supplemental Indenture thereto, dated as of July 2, 2012, by and among the
Company, the Subsidiary Guarantors parties thereto and the Trustee (the “Supplemental Indenture”), and designated as the “6.875% Senior Notes due 2023.” The Original Indenture, as amended and supplemented by the Supplemental
Indenture, is referred to herein as the “Indenture.” The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such 

  
 A-3

 
terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured
obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes or any other series of Securities that may be issued thereunder. 
 (5) OPTIONAL REDEMPTION. Except as described below, the Notes are not redeemable until July 15, 2017. On and after July 15, 2017, the Company may redeem all or a part of the Notes, from
time to time, at the following Redemption Prices (expressed as a percentage of principal amount) plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable Redemption Date (subject to the rights of Holders of Notes on the
relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on July 15 of the years indicated below: 

 

					
	 Year
	  	Redemption
Price	 
	 2017
	  	 	103.438	% 
	 2018
	  	 	102.292	% 
	 2019
	  	 	101.146	% 
	 2020 and thereafter
	  	 	100.000	% 

 At any time or from time to time prior to July 15, 2017, the Company may also redeem all or a part
of the Notes, at a Redemption Price equal to the Make-Whole Price, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. 

“Make-Whole Price” with respect to any Notes to be redeemed, means an amount equal to the greater of: 

(1) 100% of the principal amount of such Notes; and 
 (2) the sum of the present values of (a) the Redemption Price of such Notes at July 15, 2017 (as set forth above) and (b) the remaining scheduled payments of interest from the Redemption
Date to July 15, 2017 (not including any portion of such payments of interest accrued as of the Redemption Date) discounted back to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate (as defined below) plus 50 basis points; 
 plus, in the case of both (1) and (2), accrued and unpaid interest on such Notes,
if any, to the Redemption Date. 
 “Comparable Treasury Issue” means, with respect to Notes to be redeemed, the
U.S. Treasury security selected by an Independent Investment Banker as having a maturity most nearly equal to the period from the Redemption Date to July 15, 2017, that would be utilized at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of a comparable maturity; provided that if such period is less than one year, then the U.S. Treasury security having a maturity of one year shall be used. 

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury
Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such
Reference Treasury Dealer Quotations. 
 “Independent Investment Banker” means J.P. Morgan Securities LLC,
Citigroup Global Markets Inc. or one of their respective successors, or, if such firms or their respective successors, if any, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking
institution of national standing appointed by the Company. 

  
 A-4

 “Reference Treasury Dealer” means each of J.P. Morgan Securities LLC,
Citigroup Global Markets Inc., a primary Government Securities dealer in New York City (each a “Primary Treasury Dealer”) designated by Wells Fargo Securities, LLC and two additional Primary Treasury Dealers selected by the Company, and
their respective successors; provided, however, that if any such firm or any such successor, as the case may be, shall cease to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00
p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate” means,
with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(159)” or any
successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant
Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the stated maturity, yields for the two published maturities most closely corresponding to the Comparable
Treasury Issue shall be determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during
the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed
as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 

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 will 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. 

Prior to July 15, 2015, the Company may on any one or more occasions redeem up to 35% of the principal amount of the Notes, with all
or a portion of the net cash proceeds of one or more Equity Offerings at a Redemption Price equal to 106.875% of the principal amount thereof, plus accrued and unpaid interest, if any, on the Notes redeemed to the Redemption Date (subject to the
right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date); provided that: 
 (1) at least 65% of the aggregate principal amount of the Notes issued on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains Outstanding after each such redemption; and

 (2) the redemption occurs within 180 days after the closing of such Equity Offering. 

Notice of any redemption upon an Equity Offering may be given prior to the completion of the related Equity Offering, and any such
redemption or notice may at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to completion of the related Equity Offering. 

  
 A-5

 In the event that Holders of at least 90% of the aggregate principal amount of the
Outstanding Notes accept a Change of Control Offer and the Company (or any third party making such Change of Control Offer, in lieu of the Company, as described in the sixth paragraph of Section 1110 of the Supplemental Indenture) purchases all
of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following a Change of Control Payment Date, to redeem all, but not less than all, of the
Notes that remain Outstanding at a Redemption Price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain Outstanding, to the date of
redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date). 
 If a Change of Control occurs at any time on or prior to July 15, 2013, the Company may, at its option, redeem all, but not less than all, of the Notes, at a Redemption Price equal to 110.0% of the
principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the Redemption Date (subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date). If the Company
elects to exercise this redemption right, it must do so by mailing a redemption notice to each Holder with a copy to the Trustee within 60 days following the Change of Control (or, at the Company’s option, prior to such Change of Control but
after the transaction giving rise to such Change of Control is publicly announced). Any such redemption may be conditioned upon the Change of Control occurring if the notice is mailed prior to the Change of Control. If the Company exercises this
Change of Control redemption right, it may elect not to make the Change of Control Offer required by Section 1110 of the Supplemental Indenture, unless it defaults in payments due upon redemption. 

Unless the Company defaults in the payment of the Redemption Price, interest, if any, will cease to accrue on the Notes or portions
thereof called for redemption on the applicable Redemption Date. 
 (6) MANDATORY REDEMPTION. The Company is not required
to make mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Company may be required to offer to purchase Notes pursuant to Section 1110 or 1115 of the Supplemental Indenture.

 (7) REPURCHASE AT THE OPTION OF HOLDER. 

(a) If there is a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”)
to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess $2,000) of each Holder’s Notes at a purchase price in cash equal to not less than 101% of the aggregate principal amount thereof plus
accrued and unpaid interest, if any, thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date (the “Change of Control Payment”). Within 30
days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 

(b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within 10 Business Days of each
date on which the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in the Indenture with respect to offers to purchase 

  
 A-6

 
or redeem with the proceeds of sales of assets pursuant to Section 1115 of the Supplemental Indenture to purchase the maximum principal amount of Notes and such other pari passu Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, in accordance with the procedures set forth in the
Indenture. If any Excess Proceeds remain unapplied after the consummation of an Asset Sale Offer, the Company (or any Restricted Subsidiary) may use the Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will use the Excess Proceeds to purchase the Notes and such other pari passu Indebtedness on a pro
rata basis. Holders of Notes that are the subject of an offer to purchase will receive notice of an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled
“Option of Holder to Elect Purchase” attached to the Notes. 
 (8) NOTICE OF REDEMPTION. Notice of redemption
will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date
if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes
held by a Holder are to be redeemed. 
 (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without
coupons in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Security Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of its Notes, and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need
not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a
period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 
 (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of a majority in aggregate principal
amount of the Notes then Outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing default or compliance with any provision of the Indenture or the
Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the Notes then Outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for,
Notes). Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to, among other things, cure any ambiguity, defect or inconsistency, or make any change that does not adversely affect the rights or
interests of any such Holder. 
 (12) DEFAULTS AND REMEDIES. In the case of an Event of Default arising from events of
bankruptcy or insolvency specified in clause (9) or (10) of Section 601 of the Supplemental Indenture, all Outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate 

  
 A-7

 
principal amount of the then Outstanding Notes may declare all the Notes to be due and payable immediately by notice in writing to the Company specifying the Event of Default. Holders of the
Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders of the Notes notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest) if and so long as the Trustee in good faith
determines that withholding the notice is in the interests of the Holders of the Notes. The Company is required to deliver to the Trustee annually an Officers’ Certificate regarding the compliance with the Indenture, and the Company is
required, within five Business Days after becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. The Holders of a majority in aggregate principal amount of the Notes then
Outstanding may on behalf of the Holders of all of the Notes waive any past default and its consequences under the Indenture, except a default in the payment of interest or any premium on, or the principal of, the Notes and except as provided in
Section 613(2) of the Supplemental Indenture. The Holders of a majority in aggregate principal amount of the then Outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available
to the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, or that may involve the Trustee in personal liability, and may take any other action it deems proper that is
not inconsistent with any such direction received from Holders of Notes. 
 (13) TRUSTEE DEALINGS WITH COMPANY. The
Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 

(14) NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator, stockholder, member, manager or partner of the
Company or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or any Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

(15) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating
agent. 
 (16) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN
COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

(17) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP and CINS numbers to be printed on the Notes, and the Trustee may use CUSIP and CINS numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed
on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

 6.1.1 New Indications;
Relevant New Indications. 
 (a) Should either Party wish to amend the Development Plan to include an
additional Agreed Indication (in addition to the SLE Indication) it shall make a proposal in writing to the AGC. Such proposal shall identify the relevant indication (each a “New Indication”) and shall include all information
(including a draft Development Plan for such New Indication) in such Party’s possession and Control that is reasonably required by the other Party to evaluate: (i) *** for pursuing Development of the Licensed Compound in such New
Indication; and (ii) *** the Development of the Licensed Compound in any Agreed Indication (the “Development Factors”). *** The AGC shall have a reasonable period of time (to be not less than *** calendar days from receipt of
such relevant information as a reasonably prudent person would otherwise need in order to assess the Development Factors from the Party making the proposal) to determine whether or not (x) the proposed New Indication should be an Agreed
Indication or (y) whether further investigation, including clinical studies, of the potential of such proposed New Indication to become an Agreed Indication is warranted. If the AGC concludes that further study is warranted then, pursuant to
the other provisions of this Section 6.1, such study should be undertaken and the matter will be resubmitted to the AGC upon completion of any such further study. If the AGC decides that the proposed New Indication should be an Agreed
Indication, such New Indication shall be deemed to be an Agreed Indication from the date of such decision. Once a New Indication becomes an Agreed Indication, UCB *** will submit a proposed Development Plan for such Agreed Indication to the AGC as
soon as practicable (to be not less than *** calendar days from the decision unless an extension is reasonably required). For the avoidance of doubt, except as otherwise set forth in this Section 6.1, UCB *** shall secure AGC approval of a
given indication as an Agreed Indication hereunder before any Development or Commercialization of the Licensed Compound and Licensed Products for such indication pursuant to this Agreement. 

(b) Without limiting the provisions of Section 6.1.1 (a), the Parties agree that promptly, and in any event not later
than *** calendar days after the ***, the Parties shall cause members of their respective scientific and marketing groups to meet with representatives of *** to discuss the scientific and commercial merit of developing the Licensed Compound for any
of the following indications: ***, in order to assist UCB *** in evaluating each such New Indication in light of

containing a scientific rationale for such addition. UCB *** shall fully and fairly consider the input of Immunomedics and its representatives, including any clinical experts who may be invited to attend and shall, without being arbitrary and
capricious, consider, regardless of whether or not clinical data exists, whether an assessment of the Development Factors reasonably recommends a clinical study be undertaken with respect to such indications. If in connection with such evaluation,
UCB *** that another indication should be evaluated for Development hereunder, UCB may, with Immunomedics advice and consent, substitute any such indication for one of those enumerated in this Section 6.1.1(b). 

(c) No later than *** months ***, UCB will select *** indication discussed pursuant to Section 6.1.1 (b) (which

Compound for ***), and such Relevant New Indication Study(ies) will be commenced by UCB within *** after the ***. Any Relevant New Indication Study performed pursuant to this Section 6.1.1 will not require approval of the AGC. 

(d) If following completion of the Relevant New indication Study, UCB *** that, in light of the Development Factors, the
Relevant New Indication should become an Agreed Indication, UCB shall make an appropriate proposal to such effect to the AGC in accordance with the provisions of Section 6.1.1 (a) and shall vote in favor of making such Relevant New
Indication an Agreed Indication. If following the completion of the Relevant New Indication Study, UCB *** that the Relevant New Indication should not become an Agreed Indication, UCB will provide Immunomedics with a reasonably detailed written
explanation as to the reasons underlying such determination. 
 6.1.2 Each determination by UCB *** as to whether
and to what extent a proposed New Indication should be the subject of further study or if any New Indication or Relevant New Indication should be an Agreed Indication, shall not be arbitrary or capricious and shall, subject to the next sentence, be
based upon the Development Factors. Without limiting the foregoing, for the purposes of this Section 6.1, when evaluating the Development Factors, including whether or not there is a reasonable scientific and commercial basis to pursue or not
pursue Development of the Licensed Compound or the Licensed Products in any New Indication, including any Relevant New Indication, UCB shall be entitled to take into account all reasonable relevant factors, including, without limitation
