	SECTION 104.	Acts of Holders; Record Dates. 

 Whenever in this Indenture it is provided
that the Holders of a specified percentage in aggregate principal amount of the Securities of any or all series may take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of
any other action) the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in
person or by agent or proxy appointed in writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with procedures approved by the Trustee, (c) by a combination of such
instrument or instruments and any such record of such a meeting of Holders or (d) in the case of Securities evidenced by a Global Security, by any electronic transmission or other message, whether or not in written format, that complies with
the Depositary’s applicable procedures. Such evidence (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the relevant Holders. Proof of execution of any such instrument or of a
writing appointing any such agent or proxy shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 

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

  
 9 

 Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder
of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be
done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
 The
Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, 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 Securities of the relevant series 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
(the “Expiration Date”) by Holders of the requisite principal amount of Outstanding Securities of such series 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 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 Securities of the relevant series 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 Securities of the relevant series in the manner set
forth in Section 106. 
 The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to
in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series 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 Securities of such series 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 Securities of the relevant series 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 Securities of the
relevant series in the manner set forth in Section 106.  

  
 10 

 With respect to any record date set pursuant to this Section, the party hereto which sets
such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new
Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, 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 any particular Security may do so with
regard to all or any part of the principal amount of such Security 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 105.	Notices, Etc., to Trustee and Company. 

 Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: 

(1) the Trustee by any Holder or by the Company or any Subsidiary Guarantor shall be sufficient for 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 Department; or 

(2) the Company or any Subsidiary Guarantor by the Trustee or by any Holder shall be sufficient for every purpose hereunder
(unless otherwise herein expressly provided) if in writing in the English language and mailed, first-class postage prepaid, in the case of the Company addressed to it at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the Trustee by the Company and, in the case of any Subsidiary Guarantor, to it at the address of the Company’s principal office specified in the first paragraph of this
instrument, Attention: Chief Financial Officer, or at any other address previously furnished in writing to the Trustee by such Subsidiary Guarantor. 

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give
such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the

  
 11 

 
Company elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the
Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such
instructions notwithstanding such instructions’ conflict or are inconsistent with a subsequent written instruction. The Company agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions
to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. 
  

	SECTION 106.	Notice to Holders; Waiver. 

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

 

	SECTION 107.	Incorporation by Reference of Trust Indenture Act; Conflict with Trust Indenture Act. 

The Issuer hereby voluntarily subjects this Indenture to the provisions of the Trust Indenture Act which are mandatory for indentures qualified
thereunder. Such mandatory provisions are incorporated by reference and made a part of this Indenture. If any provisions in the body of this Indenture limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under
such Act to be a part of and govern indentures qualified thereunder, the latter provision shall control. If any provision of this 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 this Indenture as so modified or to be excluded, as the case may be.

time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all
Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be

proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity or security satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this
series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity or security. The foregoing shall not apply to
any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the

a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like

transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

	SECTION 204.	Form of Subsidiary Guarantee. 

 SUBSIDIARY GUARANTEE 

For value received, each of the Subsidiary Guarantors named (or deemed herein to be named) below hereby jointly and severally fully and
unconditionally guarantees to the Holder of the Security upon which this Subsidiary Guarantee is endorsed, and to the Trustee on behalf of such Holder, the due and prompt payment of the principal of (and premium, if any) and interest on such
Security when and as the same shall become due and payable, whether at the Stated Maturity, by acceleration, call for redemption, offer to purchase or otherwise, according to the terms thereof and of the Indenture referred to therein and to cover
all the rights of the Trustee under Section 607. In case of the failure of the Company promptly to make any such payment, each of the Subsidiary Guarantors hereby jointly and severally agrees to cause such payment to be made promptly when and
as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made by the Company. 

Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be absolute and
unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or the Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence granted to the
Company or any other guarantor, or any consent to departure from any requirement of any other guarantee of all or of any of the Securities of this series, or any other circumstances which might otherwise constitute a legal or equitable discharge or
defense of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount of such
Security, or increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand of payment, any requirement that the Trustee or any of the Holders
protect, secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the event
of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this
Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in such Security and in this Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the continuance of
an Event of Default with respect to Securities of this series, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities of this series, to collect interest
on the Securities of this series, or to enforce or exercise any other right or remedy with respect to the Securities of this series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the
amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.  

No reference herein to the Indenture and no provision of this Subsidiary Guarantee or of the Indenture shall alter or impair the Subsidiary
Guarantee of any Subsidiary Guarantor, which is absolute and unconditional, of the due and prompt payment of the principal (and premium, if any) and interest on the Security upon which this Subsidiary Guarantee is endorsed. 

  
 20 

 Each Subsidiary Guarantor shall be subrogated to all rights of the Holder of this Security
against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of this Security pursuant to the provisions of its Subsidiary Guarantee or 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 the principal of (and premium, if any) and interest on this Security and all other Securities of this series issued under the Indenture
shall have been paid in full. 
 This Subsidiary Guarantee shall remain in full force and effect and continue to be effective should
any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the
Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of this series is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any Holder of the Securities of this series, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or
performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities of this series shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned. 
 The Subsidiary Guarantors or any particular Subsidiary Guarantor
shall be released from this Subsidiary Guarantee upon the terms and subject to certain conditions provided in the Indenture. 
 By delivery
to the Trustee of a supplement to the Indenture referred to in the Security upon which this Subsidiary Guarantee is endorsed in accordance with the terms of the Indenture, each Person that becomes a Subsidiary Guarantor after the date of first
issuance of the Securities of this series will be deemed to have executed and delivered this Subsidiary Guarantee for the benefit of the Holder of the Security upon which this Subsidiary Guarantee is endorsed with the same effect as if such
Subsidiary Guarantor was named below and has executed and delivered this Subsidiary Guarantee. 
 All terms used in this Subsidiary
Guarantee which are defined in the Indenture shall have the meanings assigned to them in such Indenture. 
 This Subsidiary Guarantee shall
not be valid or obligatory for any purpose until the certificate of authentication on the Security upon which this Subsidiary Guarantee is endorsed shall have been executed by the Trustee under the Indenture by manual signature. 

Reference is made to the Indenture for further provisions with respect to this Subsidiary Guarantee. 

This Subsidiary Guarantee shall be governed by and construed in accordance with the laws of the State of New York.

 IN WITNESS WHEREOF, each of the Subsidiary Guarantors has caused this Subsidiary Guarantee to be
duly executed.

otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’ Certificate referred to above or in any such indenture
supplemental hereto. 
 If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an
appropriate record of such action shall be certified by the Corporate Secretary or an Assistant Corporate Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of
the series. 
 The Securities of each series shall have the benefit of the Subsidiary Guarantees unless the Company elects otherwise upon
the establishment of a series pursuant to this Section 301. 
  

	SECTION 302.	Denominations. 

 The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable
in denominations of $1,000 and any integral multiple thereof. 
  

	SECTION 303.	Execution, Authentication, Delivery and Dating. 

 The Securities shall be executed on
behalf of the Company by its Chairman of the Board of Directors, its President, its Chief Financial Officer or one of its Vice Presidents. The Securities shall be attested by the Company’s Corporate Secretary, one of its Assistant Corporate
Secretaries, its Treasurer or one of its Assistant Treasurers. The signature of any of these officers on the Securities may be manual or facsimile. 

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the
Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company and, if applicable, having endorsed thereon the Subsidiary Guarantees executed as provided in Section 1303 by the Subsidiary Guarantors to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance with the Company 

  
 26 

 
Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating, 
 (1) if the form of such Securities has been established by or
pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture; 

(2) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301,
that such terms have been established in conformity with the provisions of this Indenture; and 
 (3) that such Securities,
when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, and, if applicable, the
Subsidiary Guarantees endorsed thereon will constitute valid and legally binding obligations of the Subsidiary Guarantors, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 If such form or terms have
been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture
or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Notwithstanding the provisions of Section 301 and of the
preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of
Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such
series to be issued. 
 Each Security shall be dated the date of its authentication. 

No Security or Subsidiary Guarantee shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence,
that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this
Indenture. 

  
 27 

	SECTION 304.	Temporary Securities. 

 Pending the preparation of definitive Securities of any series,
the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities and, if applicable, having endorsed thereon the Subsidiary Guarantees in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing
such Securities and, if applicable, Subsidiary Guarantees may determine, as evidenced by their execution of such Securities and Subsidiary Guarantees. 

If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series 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 Securities of any series, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount and, if applicable, having endorsed thereon Subsidiary Guarantees
executed by the Subsidiary Guarantors. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 

 

	SECTION 305.	Registration, Registration of Transfer and Exchange. 

 The Company shall cause to be kept
at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security
Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the
purpose of registering Securities and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any
Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. 

At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized
denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. 

  
 28 

 
Whenever any Securities are so surrendered for exchange, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and the
Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities and,
if applicable, the Subsidiary Guarantees endorsed thereon issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company and, if applicable, the respective Subsidiary Guarantors, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities and Subsidiaries Guarantees surrendered upon such registration of transfer or exchange. 

Every Security 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 his attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906, 1107 or otherwise not involving any
transfer. 
 If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be
required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of
a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption
in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 The provisions of clauses (1), (2),
(3) and (4) below shall apply only to Global Securities: 
 (1) Each Global Security authenticated under this
Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture. 
 (2) Notwithstanding any other provision in this Indenture, no Global Security
may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless
(A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the
Company fails to appoint a successor Depositary within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Depositary shall have notified the

  
 29 

 
Trustee of its decision to exchange such Global Security for Securities in certificated form or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing
as have been specified for this purpose as contemplated by Section 301. 
 (3) Subject to clause (2) above, any
exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall
direct. 
 (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of,
a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in
the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
 None of the Trustee, the Paying Agent or
the Security Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any
Security (including any transfers between or among Depositary participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by,
and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

 

	SECTION 306.	Mutilated, Destroyed, Lost and Stolen Securities. 

 If any mutilated Security is
surrendered to the Trustee, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same
series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the
Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless from
any loss that any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, if applicable the Subsidiary
Guarantors shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about
to become due and payable or is to be converted, the Company in its discretion may, instead of issuing a new Security, pay or authorize the conversion of such Security (without surrender thereof save in the case of a mutilated Security). 

  
 30 

 Upon the issuance of any new Security 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 Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, and, if applicable, the
Subsidiary Guarantees endorsed thereon, shall constitute an original additional contractual obligation of the Company and, if applicable, the respective Subsidiary Guarantors, whether or not the destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series 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, payment or conversion of mutilated, destroyed, lost or stolen Securities. 
  

	SECTION 307.	Payment of Interest; Interest Rights Preserved. 

 Except as otherwise provided as
contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is promptly paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on
any Security of any series which is payable, but is not promptly 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 Securities of such series
(or their respective Predecessor Securities) 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 Security of such series 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 

  
 31 

 
be given to each Holder of Securities of such series in the manner set forth in Section 106, 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 Securities of such series (or their respective Predecessor Securities) are registered at the close
of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2) The
Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities 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 Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
  

	SECTION 308.	Persons Deemed Owners. 

 Prior to due presentment of a Security 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 Security is registered as the owner of such Security for the purpose of
receiving payment of principal of and any premium and (subject to Section 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, any Subsidiary Guarantor, the
Trustee nor any agent of the Company, any Subsidiary Guarantor, or the Trustee shall be affected by notice to the contrary. 
 None of the
Company, the Trustee, the Paying Agent or the Security Registrar shall have any responsibility or obligation to any beneficial owner in a Global Security, a Depositary member or participant or other Person with respect to the accuracy of the records
of the Depositary or its nominee or of any Depositary member or participant, with respect to any ownership interest in the Securities or with respect to the delivery to any Depositary member or participant, beneficial owner or other Person (other
than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under
the Securities and this Indenture shall be given or made only to or upon the order of the registered holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of beneficial owners in the Global Security
shall be exercised only through the Depositary subject to the applicable procedures. The Company, the Trustee, the Paying Agent and the Security Registrar shall be entitled to rely and shall be fully protected in relying upon information furnished
by the Depositary with respect to its members, participants and any beneficial owners. The Company, the Trustee, the Paying Agent and the Security Registrar shall be entitled to deal with the Depositary, and any nominee thereof, that is the

  
 32 

 
registered holder of any Global Security for all purposes of this Indenture relating to such Global Security (including the payment of principal, premium, if any, and interest and additional
amounts, if any, and the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Security) as the sole holder of such Global Security and shall have no obligations to the beneficial owners
thereof. None of the Company, the Trustee, the Paying Agent or the Security Registrar shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Security, for the records of the Depositary,
including records in respect of beneficial ownership interests in respect of any such Global Security, for any transactions between the Depositary and any Depositary member or participant or between or among the Depositary, any Depositary member or
participant and/or any holder or owner of a beneficial interest in such Global Security, or for any transfers of beneficial interests in any such Global Security. 

Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Global Security or shall impair, as between such Depositary and
owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security. 

 

	SECTION 309.	Cancellation. 

 All Securities surrendered for payment, redemption, purchase,
registration of transfer or exchange or for credit against any sinking fund payment 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 Securities 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 Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. 

 

	SECTION 310.	Computation of Interest. 

 Except as otherwise specified as contemplated by
Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

caused to be deposited with the Trustee as trust funds in trust for the purpose money in an amount sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on such Securities not theretofore

 Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 607, any surviving rights of conversion, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee

 Subject to the provisions of the last paragraph of
Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this 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 money has been deposited with the Trustee.

	SECTION 502.	Acceleration of Maturity; Rescission and Annulment. 

 If an Event of Default (other than
an Event of Default with respect to the Company specified in Section 501(8) or 501(9)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less
than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the
principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or
specified amount) shall become immediately due and payable. If an Event of Default with respect to the Company specified in Section 501(8) or 501(9) with respect to Securities of any series at the time Outstanding occurs, the principal amount
of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 

  
 37 

 At any time after such a declaration of acceleration with respect to Securities of any series has
been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written
notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company or,
if applicable, any Subsidiary Guarantor has paid or deposited with the Trustee a sum sufficient to pay 
  

	 	(A)	all overdue interest on all Securities of that series, 

  

	 	(B)	the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such
Securities, 

  

	 	(C)	to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, 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 

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities
of that series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
 No such
rescission shall affect any subsequent default or impair any right consequent thereon. 
  

	SECTION 503.	Collection of Indebtedness and Suits for Enforcement by Trustee. 

 The Company covenants
that if 
 (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and
such default continues for a period of 30 days, or 
 (2) default is made in the payment of the principal of (or premium, if
any, on) any Security at the Maturity thereof, 
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any
overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. 
 If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall

  
 38 

 
deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy. 
  

	SECTION 504.	Trustee May File Proofs of Claim. 

 In case of any judicial proceeding relative to the
Company, any Subsidiary Guarantor or any other obligor upon the Securities, or the property or creditors of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, 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 reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 

No provision of this 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 Securities or any Subsidiary Guarantee 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 505.	Trustee May Enforce Claims Without Possession of Securities. 

 All rights of action and
claims under this Indenture or the Securities or any Subsidiary Guarantee may be prosecuted and enforced by the Trustee without the possession of any of the Securities 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 reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
  

	SECTION 506.	Application of Money Collected. 

 Any money collected by the Trustee pursuant to this
Article or, after an Event of Default, any money or other property distributable pursuant to this Article in respect of the Company’s obligations under this Indenture 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 or property on account of principal or any premium or interest, upon presentation of the Securities 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 (including any predecessor trustee) under
Section 607; 

  
 39 

 SECOND: To the payment of the amounts then due and unpaid for principal of and
any premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal
and any premium and interest, respectively; and 
 THIRD: The balance, if any, to the Company or to such other Person as a
court of competent jurisdiction shall direct. 
  

	SECTION 507.	Limitation on Suits. 

 No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture or the Securities of such series, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the
Securities of that series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that
series 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 security or indemnity satisfactory to the Trustee 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 
 (5) no direction
inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 

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 this 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 this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such Holders. 
  

	SECTION 508.	Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the contractual right under the Indenture and the
applicable Securities, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to 

  
 40 

 
Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or offer by the Company to purchase the Securities
pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as applicable) and, if applicable, to convert such Security in accordance with its terms, and to institute suit for the enforcement of any such right, and such
contractual rights to receive payment and to convert shall not be impaired without the consent of such Holder. 
  

	SECTION 509.	Restoration of Rights and Remedies. 

 If the Trustee or any Holder has instituted any
proceeding to enforce any contractual right or remedy under this Indenture or a series of Securities 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 such
contractual rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  

	SECTION 510.	Rights and Remedies Cumulative. 

 Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, 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 511.	Delay or Omission Not Waiver. 

 No delay or omission of the Trustee or of any Holder of
any Securities 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 512.	Control by Holders. 

 The Holders of a majority in principal amount of the
Outstanding Securities of any series 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
Securities of such series, provided that 
 (1) such direction shall not be in conflict with any rule of law or with
this Indenture, and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with
such direction. 

  
 41 

	SECTION 513.	Waiver of Past Defaults. 

 The Holders of not less than a majority in principal amount of
the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default 

(1) in the payment of the principal of or any premium or interest on any Security of such series (including any Security 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 this Indenture) or with respect to the applicable terms of conversion of any Security of such series, or 

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

 

	SECTION 514.	Undertaking for Costs. 

 In any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken, 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, however, 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 or any Subsidiary Guarantor. 
  

	SECTION 515.	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 this Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law and covenants that it will not 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.

 ARTICLE SIX 

THE TRUSTEE 
  

	SECTION 601.	Certain Duties and Responsibilities. 

 (a) Except during the continuance of an Event of Default, 

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of
any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this
Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts, statements, opinions or conclusions stated therein). 

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

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or
its own willful misconduct, except that 
 (1) this Subsection (c) shall not be construed to limit the effect of Subsections (a) or
(d) of this Section; 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer,
unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable with
respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities of any series, determined as provided herein, relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series. 

(d) Notwithstanding the foregoing, no provision of this 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 
 (e) Whether or not therein expressly so provided, every provision of this 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. 

  
 43 

	SECTION 602.	Notice of Defaults. 

 If a default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of Securities of such series notice of such default within 90 days after it occurs or if discovered later than 90 days, promptly after such discovery; provided, however, that (a) in the case of any
default of the character specified in Section 501(5) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof, and (b) except in the case of default in the
payment of the principal of or interest on any Security, or in the payment of any sinking or purchase fund installment, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to
Securities of such series. 
  

	SECTION 603.	Certain Rights of Trustee. 

 Subject to the provisions of Section 601: 

(1) the Trustee may conclusively rely and shall be fully 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 this 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, conclusively rely upon an Officers’ Certificate and/or an Opinion
of Counsel; 
 (4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel
shall be full and complete authorization and protection 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 this Indenture at the
request or direction of any of the Holders 

  
 44 

 
pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction; 
 (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 at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 

(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 shall not be responsible or liable for any failure or delay in the performance of its obligations under this
Indenture arising out of or caused, directly or indirectly, by circumstances beyond its control, including, without limitation, any provision of any law or regulation or any act of any governmental authority; acts of God; earthquakes; fire; flood;
terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority
and governmental action; 
 (9) in no event shall the Trustee be responsible or liable for special, indirect, punitive or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 

(10) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith, without gross
negligence and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 

(11) the Trustee shall not be deemed to have notice or be charged with knowledge of any default or Event of Default unless
written notice of such default or Event of Default from the Company or any Holder is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 

(12) 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 hereunder; 

  
 45 

 (13) the Trustee may request that the Company deliver a certificate setting forth
the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which 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; and 
 (14) in order to comply
with applicable tax laws, rules and regulations (inclusive of directives, guidelines and interpretations promulgated by competent authorities) in effect from time to time (“Applicable Law”) related to this Indenture, the Company agrees
(i) to provide to the Trustee, upon request, information reasonably available to it about holders or other applicable parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine
whether it has tax related obligations under Applicable Law, (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under this Indenture to the extent necessary to comply with Applicable Law for which the
Trustee shall not have any liability and (iii) to indemnify the Trustee as per the provisions of Section 607 of this Indenture for any losses it may suffer due to the actions it takes to comply with such Applicable Law. The terms of
this section shall survive the termination of this Indenture. 
  

	SECTION 604.	Not Responsible for Recitals or Issuance of Securities. 

 The recitals contained herein
and in the Securities and the Subsidiary Guarantees, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company or the Subsidiary Guarantors, as the case may be, 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 this Indenture or of the Securities or the Subsidiary Guarantees endorsed thereon. Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof. The Trustee shall have no duty to monitor or investigate the Company’s compliance with or the breach of, or cause
to be performed or observed, any representation, warranty, or covenant, or agreement of any Person, other than the Trustee, made in this Indenture. 
  

	SECTION 605.	May Hold Securities. 

 The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company or any Subsidiary Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company and any Subsidiary Guarantor with the
same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
  

	SECTION 606.	Money Held in Trust. 

 Money 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 or any Subsidiary Guarantor, as the case may be.

  
 46 

	SECTION 607.	Compensation and Reimbursement. 

 The Company and each Subsidiary Guarantor jointly and
severally agree 
 (1) to pay to the Trustee from time to time reasonable 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 this 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 gross negligence or willful misconduct; and 
 (3) to indemnify each of the Trustee
or any predecessor Trustee and their officers, agents, directors and employees for, and to hold them harmless against, any and all loss, damage, claims, liability or expense, including taxes (other than taxes based upon, measured by or determined by
the income of the Trustee), arising out of or in connection with this Indenture, the Securities, the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim (whether
asserted by the Company, or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section, except to the extent
that such loss, damage, claim, liability or expense is due to the Trustee’s own gross negligence or willful misconduct. 
 As security
for the performance of the obligations of the Company under this Section the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of
principal of (and premium, if any) or interest on particular Securities. 
 In addition to, but without prejudice to its other rights under
this Indenture, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(8) and (9), the expenses (including the reasonable charges and expenses of its counsel) and the compensation
for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. 

“Trustee” for purposes of this Section shall include any predecessor Trustee; provided, however, that the negligence, willful
misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 
 The provisions of this
Section shall survive the satisfaction and discharge of the Indenture and the Securities, the termination for any reason of this Indenture, and the resignation or removal of the Trustee. 

  
 47 

	SECTION 608.	Conflicting Interests. 

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

 

	SECTION 609.	Corporate Trustee Required; Eligibility. 

 There shall at all times be one (and only one)
Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. 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 Securities of any series 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 610.	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 611. 

The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If
the instrument of acceptance by a successor Trustee required by Section 611 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 Securities of such series. 
 The Trustee may be removed at any
time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 

If at any time: 

(1) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by
the Company or by any such Holder, or 
 (2) 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, 

  
 48 

 then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all
Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security 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 Securities and the appointment of a successor Trustee or Trustees. 
 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 Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be
only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy,
a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series 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 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede
the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 611, any
Holder who has been a bona fide Holder of a Security of such series 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 Securities of such series. 
 The Company shall give notice of each resignation and each removal of the Trustee with respect
to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of
the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
  

	SECTION 611.	Acceptance of Appointment by Successor. 

 In case of the appointment hereunder of a
successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company, the Subsidiary Guarantors and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 
 In
case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee 

  
 49 

 
and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such
appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable
to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such
Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates. 
 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 612.	Merger, Conversion, Consolidation or Succession to Business. 

 Any Person into which the
Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such Person 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. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders of the Securities then Outstanding. In case any Securities 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 Securities so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities. 

  
 50 

	SECTION 613.	Preferential Collection of Claims Against Company and Subsidiary Guarantors. 

 If and
when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against
the Company, such Subsidiary Guarantor or any such other obligor. 
  

	SECTION 614.	Appointment of Authenticating Agent. 

 The Trustee may appoint an Authenticating Agent or
Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer, conversion or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever
reference is made in this Indenture to the authentication and delivery of Securities 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 Person 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 Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from
any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Person succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent,
provided such Person 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

  
 51 

 
Section 106 to all Holders of Securities of the series 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 607. 

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

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the Securities, and the
corresponding rights and privileges of the Trustee, shall be as provided by the Trust Indenture Act.

Guarantors shall file with the Trustee and the Commission, and transmit to Holders, such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant to such Act; provided that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same
is so required to be filed with the Commission. 
 Delivery of such information, documents and reports to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Company’s compliance
with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

	SECTION 902.	Supplemental Indentures With Consent of Holders. 

 With the consent of the Holders of not

manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall,

 (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

benefit of one or more particular series of Securities, or which 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 this Indenture of the
Holders of Securities of any other series. 
 It shall not be necessary for any Act of Holders under this Section to approve the particular
form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. 
  

	SECTION 903.	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 this Indenture, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this 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 this Indenture or otherwise.

prepared and executed by the Company, if applicable the Subsidiary Guarantees may be endorsed thereon and such new Securities may be authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 

ARTICLE TEN 
 COVENANTS

  

	SECTION 1001.	Payment of Principal, Premium and Interest. 

 The Company covenants and agrees for the
benefit of each series of Securities that it will duly and promptly pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. Principal, premium, if any, and
interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 A.M., New York City time, on the due date money deposited by the Company in immediately available funds and
designated for and sufficient to pay all principal, premium, if any, and interest then due. 
  

	SECTION 1002.	Maintenance of Office or Agency. 

 The Company will maintain in each Place of Payment for
any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment or, if applicable, for conversion, where Securities of that series may be surrendered for registration of transfer or exchange
and where notices and demands to or upon the Company or any Subsidiary Guarantor in respect of the Securities of that series or any Subsidiary Guarantee and this 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 and each Subsidiary Guarantor hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and
demands. 
 The Company may also from time to time designate one or more other offices or agencies where the Securities of one or
more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation
to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such
other office or agency. 
  

	SECTION 1003.	Money for Securities Payments to Be Held in Trust. 

 If the Company or any Subsidiary
Guarantor shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust

  
 59 

 
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 any series of Securities, it will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium or interest on any Securities of that series, 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 for any series of Securities 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, the Subsidiary Guarantors, if applicable, or any other obligor upon the Securities of that series in the making of any payment in respect of the Securities of that series, 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 Securities of that series. 

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this 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 any Security of any series 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; and the Holder of such Security 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 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 of New York, 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. 

  
 60 

	SECTION 1004.	Statement by Officers as to Default. 

 (a) The Company and the Subsidiary Guarantors
will deliver to the Trustee, within 90 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company or any
Subsidiary Guarantor, as the case may be, is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if
the Company or any Subsidiary Guarantor shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 

(b) The Company and each Subsidiary Guarantor shall deliver to the Trustee, as soon as possible and in any event within five days after the
Company or such Subsidiary Guarantor becomes aware or should reasonably become aware of the occurrence of an Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’
Certificate setting forth the details of such Event of Default or default, and the action which the Company or such Subsidiary Guarantor proposes to take with respect thereto. 

 

	SECTION 1005.	Existence. 

 Subject to Article Eight, 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 and that the loss thereof is not disadvantageous in any material respect to the Holders. 

 

	SECTION 1006.	Maintenance of Properties. 

 The Company will cause all properties used or useful
in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all
times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders. 
  

	SECTION 1007.	Payment of Taxes and Other Claims. 

 The Company will pay or discharge or cause to be
paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and
(2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge
or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 

  
 61 

	SECTION 1008.	Maintenance of Insurance. 

 The Company shall, and shall cause its Subsidiaries to, keep
at all times all of their properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible to the extent that property of similar character is usually so insured by corporations
similarly situated and owning like properties in accordance with good business practice. 
  

	SECTION 1009.	Waiver of Certain Covenants. 

 Except as otherwise specified as contemplated by
Section 301 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any of Sections 1005 through 1008 or in any
covenant provided pursuant to Section 301(21), 901(2) or 901(7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such
series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 

ARTICLE ELEVEN 

REDEMPTION OF SECURITIES 
  

	SECTION 1101.	Applicability of Article. 

 Securities of any series which are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article. 

 

	SECTION 1102.	Election to Redeem; Notice to Trustee. 

 The election of the Company to redeem any
Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series
(including any such redemption affecting only a single Security), the Company shall, at least ten Business Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 

  
 62 

	SECTION 1103.	Selection by Trustee of Securities to Be Redeemed. 

 If less than all the Securities of
any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), (a) if the Securities are represented by Global Securities, interests
in such Global Securities will be selected for redemption in accordance with the customary procedures of DTC, or (b) if the Securities are represented by definitive Securities, the particular Securities to be redeemed shall be selected by the
Trustee, from the Outstanding Securities of such series not previously called for redemption, (i) in compliance with the requirements of the principal national securities exchange on which such Securities are listed, if such Securities are
listed on any national securities exchange, and (ii) if such Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption
of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), (a) if the Securities are represented by Global Securities,
interests in such Global Securities will be selected for redemption in accordance with the customary procedures of DTC, or (b) if the Securities are represented by definitive Securities, the particular Securities to be redeemed shall be
selected by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 

In the case of a partial redemption of definitive Securities, the Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. 

The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to
the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. If any Security selected for partial
redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Upon any redemption of less than all the Securities of a series, for
purposes of selection for redemption the Company and the Trustee may treat as Outstanding Securities surrendered for conversion during the period of 15 days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any
Security authenticated and delivered during such period in exchange for the unconverted portion of any Security converted in part during such period. 

  
 63 

	SECTION 1104.	Notice of Redemption. 

 Notice of redemption shall be transmitted not less than 30
nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register; provided, however, notice of redemption may be given more than 60 days prior to the Redemption
Date if the notice is issued in connection with a satisfaction and discharge pursuant to Article Four. 
 All notices of redemption
shall state: 
 (1) the Redemption Date, 

(2) the Redemption Price, if then determinable and otherwise the method of its determination, 

(3) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the
identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to
be redeemed, the principal amount of the particular Security to be redeemed, 
 (4) that on the Redemption Date the
Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 

(5) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 

(6) that the redemption is for a sinking fund, if such is the case, 

(7) if applicable, the conversion price then in effect and the date on which the right to convert such Securities will expire,

 (8) the CUSIP, Common Code and ISIN numbers, if applicable, and that no representation is made as to the accuracy or
correctness of the CUSIP, Common Code and ISIN numbers, if applicable, if any, listed in such notice or printed on the Securities, and 

(9) the paragraph of the Securities pursuant to which the Securities are to be redeemed. 

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any Paying Agent or so segregated and held in
trust for the redemption of such Security shall be paid to the Company upon delivery of a Company Request to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such trust. 

  
 64 

	SECTION 1105.	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 1003) 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 Securities which are to be redeemed on that date. 
  

	SECTION 1106.	Securities Payable on Redemption Date. 

 Notice of redemption having been given as
aforesaid, the Securities 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 Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.  

If any Security 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 Security. 
  

	SECTION 1107.	Securities Redeemed in Part. 

 Any Security 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 his
attorney duly authorized in writing), and the Company shall execute, if applicable to Subsidiary Guarantors shall execute the Subsidiary Guarantee endorsed thereon, and the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities of the same series and 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 Security so surrendered.

 ARTICLE TWELVE 

[INTENTIONALLY OMITTED] 

ARTICLE THIRTEEN 

SUBSIDIARY GUARANTEES 
  

	SECTION 1301.	Applicability of Article. 

 Unless the Company elects to issue any series of Securities
without the benefit of the Subsidiary Guarantees, which election shall be evidenced in or pursuant to the Board Resolution or supplemental indenture establishing such series of Securities pursuant to Section 301, the provisions of this Article
shall be applicable to each series of Securities except as otherwise specified in or pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to Section 301. 

 

	SECTION 1302.	Subsidiary Guarantees. 

 Subject to Section 1301, each Subsidiary Guarantor hereby,
jointly and severally, fully and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee, the due and prompt payment of the principal of (and premium, if any) and interest on such Security when and as the
same shall become due and payable, whether at the Stated Maturity, by acceleration, call for redemption, offer to purchase or otherwise, in accordance with the terms of such Security and of this Indenture, and each Subsidiary Guarantor similarly
guarantees to the Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this Indenture. In case of the failure of the Company promptly to make any such payment, each Subsidiary Guarantor hereby, jointly and
severally, agrees to cause such payment to be made promptly when and as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made
by the Company. 
 Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be absolute,
unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or this Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence granted to the
Company or any guarantor or any consent to departure from any requirement of any other guarantee of all or any of the Securities of such series or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of
a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount of such Security, or increase the
interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or any of the Holders protect, secure, perfect
or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced 

  
 66 

 
thereby and all demands whatsoever, and covenants that this Subsidiary Guarantee will not be discharged in respect of such Security except by complete performance of the obligations contained in
such Security and in such Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their
respective rights to accelerate the maturity of the Securities of a series, to collect interest on the Securities of a series, or to enforce or exercise any other right or remedy with respect to the Securities of a series, such Subsidiary Guarantor
agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders. 

Each Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities upon which its Subsidiary Guarantee is endorsed
against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of such Security pursuant to the provisions of its Subsidiary Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor shall be entitled
to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full. 

Each Subsidiary Guarantor that makes or is required to make any payment in respect of its Subsidiary Guarantee shall be entitled to seek
contribution from the other Subsidiary Guarantors to the extent permitted by applicable law; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right
of contribution until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full. 

Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the
Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of a series, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise
be restored or returned by any Holder of the Securities, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

 

	SECTION 1303.	Execution and Delivery of Subsidiary Guarantees. 

 The Subsidiary Guarantees to be
endorsed on the Securities shall include the terms of the Subsidiary Guarantee set forth in Section 1302 and any other terms that may be set forth in the form established pursuant to Section 204. Subject to Section 1301, each of the
Subsidiary Guarantors hereby agrees to execute its Subsidiary Guarantee, in a form established pursuant to Section 204, to be endorsed on each Security authenticated and delivered by the Trustee. 

  
 67 

 The Subsidiary Guarantee shall be executed on behalf of each respective Subsidiary Guarantor by
any one of such Subsidiary Guarantor’s Chairman of the Board of Directors, Chief Executive Officer, President, one of its Vice Presidents, or its Corporate Secretary. The signature of any or all of these persons on the Subsidiary Guarantee may
be manual or facsimile. 
 A Subsidiary Guarantee bearing the manual or facsimile signature of individuals who were at any time the proper
officers of a Subsidiary Guarantor shall bind such Subsidiary Guarantor, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of the Security on which such Subsidiary
Guarantee is endorsed or did not hold such offices at the date of such Subsidiary Guarantee. 
 The delivery of any Security by the Trustee,
after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee endorsed thereon on behalf of the Subsidiary Guarantors and shall bind each Subsidiary Guarantor notwithstanding the fact that Subsidiary Guarantee
does not bear the signature of such Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby jointly and severally agrees that its Subsidiary Guarantee set forth in Section 1302 and in the form of Subsidiary Guarantee established pursuant
to Section 204 shall remain in full force and effect notwithstanding any failure to endorse a Subsidiary Guarantee on any Security. 
  

	SECTION 1304.	Release of Subsidiary Guarantors. 

 Unless otherwise specified pursuant to
Section 301 with respect to a series of Securities, each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor until the entire principal of, premium, if any, and interest on the Securities to which such
Subsidiary Guarantee relates shall have been paid in full or otherwise satisfied and discharged in accordance with the provisions of such Securities and this Indenture and all amounts owing to the Trustee hereunder have been paid; provided,
however, that if (i) such Subsidiary Guarantor ceases to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant
to Article Fifteen or (iii) all or substantially all of the assets of such Subsidiary Guarantor or all of the Capital Stock of such Subsidiary Guarantor is sold (including by sale, merger, consolidation or otherwise) by the Company or any
Subsidiary in a transaction complying with the requirements of this Indenture, then, in each case of (i), (ii) or (iii), upon delivery by the Company of an Officers’ Certificate and an Opinion of Counsel stating that all conditions
precedent herein provided for relating to the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee and this Article Thirteen have been complied with, such Subsidiary Guarantor shall be released and discharged of
its obligations under its Subsidiary Guarantee and under this Article Thirteen without any action on the part of the Trustee or any Holder, and the Trustee shall execute any documents reasonably required in order to acknowledge the release of such
Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Securities of such series and under this Article Thirteen. 
  

	SECTION 1305.	Additional Subsidiary Guarantors. 

 Unless otherwise specified pursuant to
Section 301 with respect to a series of Securities, the Company will cause any Domestic Subsidiary of the Company that becomes a Material 

  
 68 

 
Domestic Subsidiary after the date the Securities of a series are first issued hereunder to become a Subsidiary Guarantor as soon as practicable after such Subsidiary becomes a Material Domestic
Subsidiary. The Company shall cause any such Subsidiary to become a Subsidiary Guarantor with respect to the Securities by executing and delivering to the Trustee (a) a supplemental indenture, in form satisfactory to the Trustee, which subjects
such Person to the provisions (including the representations and warranties) of this Indenture as a Subsidiary Guarantor and (b) an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized and executed by such
Person and such supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this Indenture constitute the legal, valid, binding and enforceable obligations of such Person (subject to such customary exceptions
concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion). 
  

	SECTION 1306.	Limitation on Liability. 

 Any term or provision of this Indenture to the contrary
notwithstanding, the maximum amount of the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by such Subsidiary Guarantor without rendering such Subsidiary Guarantee voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

ARTICLE FOURTEEN 

[INTENTIONALLY OMITTED] 

ARTICLE FIFTEEN 

DEFEASANCE AND COVENANT DEFEASANCE 
  

	SECTION 1501.	Company’s Option to Effect Defeasance or Covenant Defeasance. 

 The Company may
elect, at its option at any time, to have Section 1502 or Section 1503 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1502 or 1503, in accordance with any applicable requirements provided pursuant to Section 301 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced in or pursuant to a Board
Resolution or in another manner specified as contemplated by Section 301 for such Securities. 
  

	SECTION 1502.	Defeasance and Discharge. 

 Upon the Company’s exercise of its option (if any) to
have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations, and each Subsidiary Guarantor shall be deemed to have been discharged from its
obligations with respect to its Subsidiary Guarantees of such Securities, as provided in this Section on and after the date the conditions set forth in Section 1504 are satisfied (herein called “Defeasance”). For this purpose, such
Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this

  
 69 

 
Indenture insofar as such Securities 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 Securities to receive, solely from the trust fund described in Section 1504 and as more fully set forth in such Section, payments in respect of
the principal of and any premium and interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the Company’s and each Subsidiary Guarantor’s obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, and, if applicable, their obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article. Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the prior exercise of its option (if any) to have Section 1503 applied
to such Securities. 
  

	SECTION 1503.	Covenant Defeasance. 

 Upon the Company’s exercise of its option (if any) to have
this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company shall be released from its obligations under Section 801(3), Sections 1005 through 1008, inclusive, and any covenants provided pursuant
to Section 301(21), 901(2) or 901(7) for the benefit of the Holders of such Securities, and (2) the occurrence of any event specified in Sections 501(5) (with respect to any of Section 801(3), Sections 1005 through 1008, inclusive,
and any such covenants provided pursuant to Section 301(21), 901(2) or 901(7)), 501(6), 501(7)), 501(10) and 501(11) shall be deemed not to be or result in an Event of Default and (3) the provisions of Article Thirteen shall cease to be
effective, in each case with respect to such Securities and Subsidiary Guarantees as provided in this Section on and after the date the conditions set forth in Section 1504 are satisfied (herein called “Covenant Defeasance”). For this
purpose, such Covenant Defeasance means that, with respect to such Securities, the Company and the Subsidiary Guarantors, as applicable, 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 (to the extent so specified in the case of Section 501(5)) or Article Thirteen, 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 this Indenture and such Securities shall be unaffected thereby. 
  

	SECTION 1504.	Conditions to Defeasance or Covenant Defeasance. 

 The following shall be the conditions
to the application of Section 1502 or Section 1503 to any Securities or any series of Securities, as the case may be: 

(1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies
the requirements contemplated by Section 609 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and
dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with

  
 70 

 
their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the
principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security
which is (i) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an
agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable
at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in clause
(x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that
(except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the
specific payment of principal or interest evidenced by such depositary receipt. 
 (2) In the event of an election to have
Section 1502 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm
that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 

(3) In the event of an election to have Section 1503 apply to any Securities or any series of Securities, as the case may
be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be
effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur. 

(4) The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither such Securities
nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 

  
 71 

 (5) No event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 501(7) and (8), at any time on or prior to the 121st
day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 121st day). 

(6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the
Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
 (7) Such Defeasance or
Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound. 

(8) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause
either the Trustee or the trust so created to be subject to the Investment Company Act. 
 (9) The Company shall have
delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 

 

	SECTION 1505.	Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. 

Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1506, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 1504
in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this 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 Securities, 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. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to Section 1504 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 Securities. 
 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 U.S. Government Obligations held by it as provided in Section 1504 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. 

  
 72 

	SECTION 1506.	Reinstatement. 

 If the Trustee or the Paying Agent is unable to apply any money
in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and
such Securities from which the Company has been discharged or released pursuant to Section 1502 or 1503 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time
as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1505 with respect to such Securities 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 Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

 ARTICLE SIXTEEN 

SINKING FUNDS 
  

	SECTION 1601.	Applicability of Article. 

 The provisions of this Article shall be applicable to any
sinking fund for the retirement of Securities of any series except as otherwise specified as contemplated by Section 301 for such Securities. 

The minimum amount of any sinking fund payment provided for by the terms of any Securities is herein referred to as a “mandatory sinking
fund payment”, and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Securities, the cash amount
of any sinking fund payment may be subject to reduction as provided in Section 1602. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities. 

 

	SECTION 1602.	Satisfaction of Sinking Fund Payments with Securities. 

 The Company (1) may deliver
Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been (x) converted or (y) redeemed either at the election of the Company pursuant to
the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities
of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided, however, that the Securities to be so credited have not been previously so credited. The
Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly. 

  
 73 

	SECTION 1603.	Redemption of Securities for Sinking Fund. 

 Not less than 35 days prior to each sinking
fund payment date for any Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 1602 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 32 days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107. 
 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the same instrument. 

  
 74 

 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, all as of
the day and year first above written.

 This First Supplemental Indenture, dated as of March 23, 2016 (this “First Supplemental
Indenture”), supplements and amends the Senior Indenture, dated as of March 23, 2016 (the “Original Indenture”), among Whiting Petroleum Corporation, a Delaware corporation (the “Company”), the Guarantors listed on the
signature page hereof and The Bank of New York Mellon Trust Company, N.A., a national banking association, as trustee (the “Trustee”). 

RECITATIONS OF THE COMPANY 

WHEREAS, the Company, the Guarantors and the Trustee have heretofore executed and delivered the Original Indenture to provide for the issuance
of the Company’s senior debt securities to be issued in one or more series; 
 WHEREAS, Section 901 of the Original
Indenture provides, among other things, that the Company, the Guarantors and the Trustee may without the consent of Holders enter into indentures supplemental to the Original Indenture to, among other things, (a) add to, change or eliminate any
of the provisions of the Original Indenture in respect of one or more series of Securities, provided that any such addition, change or elimination (i) shall neither (A) apply to any Security of any series created prior to the
execution of such supplemental indenture and entitled to the benefit of such provision nor (B) modify the rights of the Holder of any such Security with respect to such provision or (ii) shall become effective only when there is no such
Security Outstanding and (b) establish the form or terms of Securities of any series as permitted by Sections 201 and 301 of the Original Indenture; 

WHEREAS, the Company desires to provide for the issuance of a series of Securities to be designated as the “5.000% Convertible Senior
Notes due 2019” (the “Notes”), and to set forth the form and terms thereof; 
 WHEREAS, the Company proposes in and by this
First Supplemental Indenture to supplement and amend the Original Indenture, but only insofar as it will apply to the Notes; and 
 WHEREAS,
all action on the part of the Company necessary to authorize the creation and issuance of the Notes, and all action on the part of each of the Guarantors necessary to authorize its guarantee of the Notes under the Original Indenture and this First
Supplemental Indenture (the Original Indenture, as supplemented and amended by this First Supplemental Indenture, being hereinafter called the “Indenture”), have been duly taken. 

NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH: 

That, in order to establish the designation, form and terms of, and to authorize the authentication and delivery of the Notes, and in
consideration of the acceptance of the Notes by the Holders thereof and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

  
 1 

 ARTICLE 1 

DEFINITIONS AND INCORPORATION 
 BY
REFERENCE 
 Section 1.01. Definitions. 

(a) Capitalized terms used herein and not otherwise defined shall have the respective meanings assigned thereto in the Original Indenture.

 (b) Section 101 of the Original Indenture is amended and supplemented, with respect to the Notes, by inserting or restating, as the
case may be, in their appropriate alphabetical position, the following definitions: 
 “ACNTA” means (without
duplication), as of the date of determination: 
 (1) the sum of: 

(a) discounted future net revenue from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries
calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, which reserve report is prepared or reviewed by
independent petroleum engineers as to reserves accounting for at least 80% of all such discounted future net revenue and by the Company’s petroleum engineers with respect to any other reserves covered by such report, as increased by, as of the
date of determination, the discounted future net revenue from: 
 (i) estimated proved crude oil and natural gas reserves of
the Company and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such year-end reserve report, and 

(ii) estimated crude oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to extensions,
discoveries and other additions and upward determinations of estimates of proved crude oil and natural gas reserves (including previously estimated development costs incurred during the period and the accretion of discount since the prior year end)
due to exploration, development or exploitation, production or other activities which reserves were not reflected in such year-end reserve report, 

in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report), and decreased by, as
of the date of determination, the discounted future net revenue attributable to 
 (iii) estimated proved crude oil and
natural gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end reserve report produced or disposed of since the date of such year-end reserve report and 

  
 2 

 (iv) reductions in the estimated proved crude oil and natural gas reserves of
the Company and its Restricted Subsidiaries reflected in such year-end reserve report since the date of such year-end reserve report attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to
exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such year-end reserve report, 

in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report); provided, however,
that, in the case of each of the determinations made pursuant to clauses (i) through (iv), such increases and decreases shall be as estimated by the Company’s engineers, except that if as a result of such acquisitions, dispositions,
discoveries, extensions or revisions, there is a Material Change, then such increases and decreases in the discounted future net revenue shall be confirmed in writing by an independent petroleum engineer; 

(b) the capitalized costs that are attributable to crude oil and natural gas properties of the Company and its Restricted
Subsidiaries to which no proved crude oil and natural gas reserves are attributed, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest annual or quarterly financial statements; 

(c) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial
statements; and 
 (d) the greater of (I) the net book value on a date no earlier than the date of the Company’s
latest annual or quarterly financial statements or (II) the appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries as of a date no earlier than the date of the Company’s
latest audited financial statements; 
 (2) minus, to the extent not otherwise taken into account in the immediately
preceding clause (1), the sum of: 
 (a) minority interests; 

(b) any net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest
audited financial statements; 
 (c) the discounted future net revenue, calculated in accordance with SEC guidelines
(utilizing the same prices utilized in the Company’s year-end reserve report), attributable to reserves subject to participation interests, overriding royalty interests or other interests of third parties, pursuant to participation,
partnership, vendor financing or other agreements then in effect, or which otherwise are required to be delivered to third parties; 

(d) the discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same prices utilized in the
Company’s year-end 

  
 3 

 
reserve report), attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to
Volumetric Production Payments on the schedules specified with respect thereto; and 
 (e) the discounted future net revenue,
calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in the
immediately preceding clause (1)(a) (utilizing the same prices utilized in the Company’s year-end reserve report), would be necessary to satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to
Dollar-Denominated Production Payments on the schedules specified with respect thereto. 
 If the Company changes its method of accounting for its oil and
gas properties from the successful efforts method to the full cost method or a similar method of accounting, ACNTA will continue to be calculated as if the Company were still using the successful efforts method of accounting. 

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

(1) Indebtedness of any other Person existing at the time such other Person was merged with or into or became a Subsidiary of
such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Subsidiary of, such specified Person; provided, however, that Indebtedness of such
acquired Person which is redeemed, defeased, retired or otherwise repaid at the time of or substantially contemporaneously with the consummation of the transactions by which such Person merges with or into or becomes a Subsidiary of such Person
shall not be Acquired Debt; and

Person.

with any cash) is reasonably equivalent to the fair market value of the properties or assets (together with any cash) to be received by the Company or such Restricted Subsidiary, and provided further that any net cash received must be applied
in accordance with the provisions of Section 4.10 of the First Supplemental Indenture; 
 (8) the creation or

Section 1.04. Incorporation by Reference of Trust Indenture Act; Conflict with Trust Indenture Act. 

The Company hereby voluntarily subjects this First Supplemental Indenture to the provisions of the TIA which are mandatory for indentures
qualified thereunder. Such mandatory provisions are incorporated by reference and made a part of this First Supplemental Indenture. If any provisions in the body of this First Supplemental Indenture limits, qualifies or conflicts with a provision of

 ARTICLE 2 

THE NOTES 
 Section 2.01.
Creation and Form. 
 Pursuant to Sections 201 and 301 of the Original Indenture, there is hereby created a new series of Securities
designated as the “5.000% Convertible Senior Notes due 2019” (which are herein referred to as the “Notes” for purposes of this First Supplemental Indenture). The Notes shall be substantially in the form specified in Exhibit A to
this First Supplemental Indenture, shall have the terms set forth therein and shall be entitled to the benefits of the other provisions of the Original Indenture as modified by this First Supplemental Indenture and specified herein. To the extent
permitted by applicable law, in the event of any inconsistency between the terms of the Notes and the terms of this Indenture, the terms of this Indenture will control. To the extent applicable, the Initial Notes and Additional Notes will bear the
OID Legend. Each certificate representing shares of Common Stock issued upon conversion of any Note, shall, upon issuance, if such shares are subject to restriction on transfer under the Securities Act at their time of issuance, bear the Common
Stock Restricted Legend on the face thereof until the Resale Restriction Termination Date. 
 Section 2.02. Execution and
Authentication. 
 On the Issue Date, the Trustee shall authenticate and deliver $96,812,000 of Initial Notes and, at any time and from
time to time thereafter, the Trustee shall authenticate and deliver Additional Notes for original issue, in each case upon the Trustee’s receipt of a Company Order in accordance with Section 303 of the Original Indenture. Such order shall
specify the aggregate principal amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of an issuance of Additional Notes pursuant to Section 2.05 of this First
Supplemental Indenture after the Issue Date, shall certify that such issuance is in compliance with such Section 2.05 and Section 4.09 hereof. The Notes shall be issued initially in the form of Global Securities, for which The Depository
Trust Company shall act as Depositary. Notes in the form of Global Securities shall bear the legends set forth on the form of Note attached hereto. 

Section 2.03. Outstanding Notes. 

Notes outstanding at any time are all Notes authenticated by the Trustee except for those that have been converted, those canceled by it,
those delivered to it for cancellation and those described in this Section as not outstanding. Except as otherwise provided in TIA §316(a), a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the
Note. 
 If a Note is replaced pursuant to Section 306 of the Original Indenture, it ceases to be outstanding unless the Trustee and
the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser. 

  
 29 

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

Section 2.04. CUSIP Numbers. 

The Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so,
the Trustee shall use “CUSIP” numbers and corresponding “ISINs” in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such
numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. 
 Section 2.05. Issuance of Additional Notes. 

The Company shall be entitled, subject to its compliance with Section 4.09 of this First Supplemental Indenture, to issue Additional
Notes under the Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, issue price, the initial date from which interest begins to accrue, and if applicable, the
existence of resale restrictions pursuant to the Securities Act, provided that no Additional Notes may be issued with the same “CUSIP”, “ISIN” or “Common Code” number as the Initial Notes unless it is so
permitted in accordance with applicable law and such Additional Notes are fungible with the Initial Notes for U.S. federal tax purposes. The Initial Notes issued on the Issue Date and any Additional Notes shall be treated as a single class for all
purposes under the Indenture.

principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the
Redemption Date). 
 (b) Notwithstanding the provisions of clause (a) of this Section 3.02, at any time prior to December 15,
2018, the Company may on any one or more occasions redeem the 

  
 30 

 
Notes, in whole or in part, at the Redemption Price of 100% of the principal amount thereof plus the Applicable Premium as of, plus accrued and unpaid interest, if any, to, the Redemption Date
(subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date). 

The Company shall determine any Applicable Premium and shall notify the Trustee thereof in writing at least two Business Days in advance of
the payment date thereof. The Trustee shall have no responsibility for any calculation of any such amounts and may rely conclusively on the Company’s determinations thereof.

Section 1104 of the Original Indenture, the Conversion Rate and Conversion Price in effect on the date of the notice of redemption and that a Holder who elects to convert all or a portion of its Notes in lieu of redemption must submit a
Conversion Notice with respect to such Notes being converted on or before the close of business on the Business Day immediately preceding the Redemption Date.

Except as set forth under Sections 4.10 and 4.15 hereof, the Company shall not be required to make mandatory redemption or sinking fund
payments with respect to the Notes or to repurchase the Notes at the option of the Holders. 
 Section 3.04. Offer to Purchase by
Application of Excess Proceeds. 
 In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence an
offer to all Holders to purchase Notes (an “Asset Sale Offer”), it shall follow the procedures specified below. 
 The
Asset Sale Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by Applicable Law (the “Offer Period”). No later than five Business
Days after the termination of the Offer Period (the “Settlement Date”), the Company shall purchase and pay for the principal amount of Notes required to be purchased pursuant to Section 4.10 hereof (the “Offer
Amount”) or, if less than the Offer Amount has been tendered, all Notes validly tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the manner prescribed in the Notes. 

Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to each of the Holders, with a copy to the
Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the
Asset Sale Offer, shall state: 
 (a) that the Asset Sale Offer is being made pursuant to this Section 3.04 and
Section 4.10 hereof and the length of time the Asset Sale Offer shall remain open, including the time and date the Asset Sale Offer will terminate (the “Termination Date”); 

  
 31 

 (b) the Offer Amount and the purchase price; 

(c) that any Note not tendered or accepted for payment shall 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
shall cease to accrue interest after the Settlement Date; 
 (e) that Holders electing to have a Note purchased pursuant to
an Asset Sale Offer may only elect to have all of such Note purchased and may not elect to have only a portion of such Note purchased; 

(f) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note,
with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Company or a Paying Agent at the address specified in the notice, before the Termination Date; 

(g) that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be, receives,
prior to the Termination Date, 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 surrendered by Holders, and Pari Passu
Indebtedness surrendered by holders or lenders, collectively, exceeds the amount the Company is required to repurchase, the Trustee shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate
principal amount of tendered Notes and Pari Passu Indebtedness (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of equal to $2,000 or any integral $1,000 multiple in excess thereof, shall be
purchased); 
 (i) that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer); and 
 (j) the Conversion Rate
and Conversion Price then in effect and that a Holder that has tendered its Notes for repurchase who wishes to withdraw such Notes and convert them must submit a valid notice of withdrawal and Conversion Notice prior to the close of business on the
Business Day immediately preceding the Settlement Date. 
 If any of the Notes subject to an Asset Sale Offer is in the form of a Global
Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to repurchases. 

Promptly after the Termination Date, the Company shall, to the extent lawful, accept for payment Notes or portions thereof tendered pursuant
to the Asset Sale Offer in the aggregate principal amount required by Section 4.10 hereof, and prior to the Settlement Date it shall deliver 

  
 32 

 
to the Trustee 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 3.04 and
Section 4.10 hereof. On the Settlement Date, the Company or the Paying Agent, as the case may be, shall mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the
Company for purchase, and the Company shall issue a new Note, and the Trustee shall authenticate and mail or deliver 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 shall publicly announce the results of the Asset Sale Offer on or before the Settlement Date.

The Company shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes and, if applicable, the Early
Conversion Payment due in connection with an Early Conversion and, if applicable, the Company agrees to deliver the shares of Common Stock (and any cash in lieu of fractional shares) due in connection with an Early Conversion or a Mandatory
Conversion, each on the dates and in the manner provided in the Notes. Principal, premium, if any, interest, the Early Conversion Payment, if applicable, and cash in lieu of fractional shares in connection with any conversion shall be considered
paid on the date due if the Paying Agent, if other than the Company or a Guarantor, holds as of 11:00 a.m. New York time on the due date money deposited by the Company or a Guarantor in immediately available funds and designated for and sufficient
to pay all principal, premium, if any, interest then due, the Early Conversion Payment, if applicable, and cash in lieu of fractional shares in connection with any Early Conversion or Mandatory Conversion. 

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

The Company shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee) where Notes may be
presented or surrendered for payment or conversion and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. The Company shall 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. 

  
 33 

 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. Further, if at any time there shall be no such office or agency in the City of New York where the Notes may be presented or
surrendered for payment, the Company shall forthwith designate and maintain such an office or agency in the City of New York, in order that the Notes shall at all times be payable in the City of New York. The Company shall give prompt written notice
to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 The Company
hereby appoints the Trustee as Paying Agent and Conversion Agent, and designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 301 of the Original Indenture. 

Section 4.03. Reports. 

(a) Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long
as any Notes are outstanding, the Company will file with the SEC (unless the SEC will not accept such a filing) for public availability within the time period specified in the SEC’s rules and regulations under the Exchange Act and, within 10
Business Days of filing, or attempting to file, the same with the SEC, furnish to the Trustee and, upon its request, to any of the Holders of the Notes: 

(1) all quarterly and annual financial and other information with respect to the Company and its Subsidiaries that would be
required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with
respect to the annual information only, a report thereon by the Company’s certified independent accountants; and 
 (2)
all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports. 
 The Company’s
filing of any such information, document or report with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system or any successor thereto shall satisfy the reporting obligation described above. 

The Company shall at all times comply with TIA § 314(a). 

(b) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information
required by paragraph (a) of this Section 4.03 shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial statements and in Management’s Discussion and
Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted
Subsidiaries. 
 (c) Delivery of such information, documents and reports to the Trustee is for informational purposes only and the
Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 

  
 34 

 Section 4.04. Compliance Certificate. 

(a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate 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 the Company has kept, observed, performed and
fulfilled its obligations under the Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained
in the Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of the Indenture (or, if a Default or Event of Default with respect to the Notes shall have occurred, describing all such Defaults
or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which
payments of interest on the Notes are prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. 

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

Section 4.05. Taxes. 

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

Section 4.06. Stay, Extension and Usury Laws. 

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

  
 35 

 Section 4.07. Limitation on 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 to which the Company or any of its Restricted Subsidiaries is a party) 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 or payable to the Company or
a Restricted Subsidiary of the Company); 
 (2) purchase, redeem or otherwise acquire or retire for value (including, without
limitation, in connection with any merger or consolidation to which the Company is a party) any Equity Interests of the Company or any direct or indirect parent of the Company; 

(3) make any principal payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness that is subordinated to the Notes or the Subsidiary Guarantees prior to any scheduled repayment or scheduled maturity, except a payment, purchase, redemption, defeasance or other acquisition of any such Indebtedness in anticipation of
satisfying a sinking fund obligation, principal installment or the Stated Maturity thereof, in each case, due within one year of the date of such payment, purchase, redemption, defeasance or other acquisition; or 

(4) make any Restricted Investment (all such payments and other actions set forth in these 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 4.09; and 
 (3) such Restricted Payment, together with the aggregate amount of
all other Restricted Payments made by the Company and its Restricted Subsidiaries after May 11, 2004 (excluding Restricted Payments permitted by clauses (2), (3), (4), (6), (7) and (8) of the next succeeding paragraph), is 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 April 1, 2004 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 

  
 36 

 (b) 100% of the aggregate net cash proceeds received by the Company (including
the fair market value of any Additional Assets to the extent acquired in consideration of Equity Interests of the Company (other than Disqualified Stock)) since May 11, 2004 as a contribution to its common equity capital or from the issue or
sale of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt 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), plus 

(c) to the extent that any Restricted Investment that was made after May 11, 2004 is sold for cash or otherwise liquidated
or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment, plus 

(d) to the extent that any Unrestricted Subsidiary of the Company is redesignated as a Restricted Subsidiary after May 11,
2004, the lesser of (i) the fair market value of the Company’s Investment in such Subsidiary as of the date of such redesignation or (ii) such fair market value as of the date on which such Subsidiary was originally designated as an
Unrestricted Subsidiary. 
 The preceding provisions will not prohibit: 

(1) the payment of any dividend or distribution or the consummation of any irrevocable redemption of debt that is subordinate
to the Notes, within 60 days after the date of declaration of such dividend or the delivery of any irrevocable notice of redemption, as the case may be, if the dividend, distribution or redemption payment on the date of declaration or the date of
the notice of redemption, as the case may be, would have complied with the provisions of the Indenture; 
 (2) the
redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness of the Company or any Guarantor or of any Equity Interests of the Company in exchange for, or out of the net cash proceeds of the substantially
concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock), with a sale being deemed substantially concurrent if such redemption, repurchase, retirement, defeasance or acquisition
occurs not more than 120 days after such sale; provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition will be excluded from clause
(3)(b) of the preceding paragraph; 
 (3) the defeasance, redemption, repurchase, retirement or other acquisition of
subordinated Indebtedness of the Company or any Guarantor with the net cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness; 

(4) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to the holders of its Equity
Interests on a pro rata basis; 

  
 37 

 (5) the repurchase, redemption or other acquisition or retirement for value of
any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any current or former director, officer, employee or consultant of the Company or any of its Restricted Subsidiaries pursuant to any equity subscription
agreement or plan, stock option agreement or similar agreement or plan; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $2.0 million in any twelve-month
period; 
 (6) the acquisition of Equity Interests by the Company in connection with the exercise of stock options or stock
appreciation rights by way of cashless exercise; 
 (7) the purchase, repurchase, redemption, defeasance or other acquisition
or retirement for value of subordinated Indebtedness of the Company or any Restricted Subsidiary (a) at a purchase price not greater than 101.0% of the principal amount thereof (plus accrued and unpaid interest) in the event of a Change of
Control in accordance with provisions similar to Section 4.15 or (b) at a purchase price not greater than 100.0% of the principal amount thereof (plus accrued and unpaid interest) in accordance with provisions similar to Section 4.10;
provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Change of Control Offer or Asset Sale Offer, as applicable, as provided in such covenants
with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Change of Control Offer or Asset Sale Offer; 

(8) the payment of cash in lieu of fractional shares of Capital Stock in connection with any transaction otherwise permitted
under this Section 4.07; or 
 (9) other Restricted Payments in an aggregate amount since May 11, 2004 not to
exceed $25.0 million; 
 provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under the
preceding clause (9), no Default or Event of Default shall have occurred and be continuing or would be caused thereby. 
 The amount of all
Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant
to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant will be determined, in the case of amounts under $50.0 million, by an officer of the Company and, in the case of amounts of
$50.0 million or more, by the Board of Directors of the Company, whose determination shall be evidenced by a Board Resolution. Not later than the date of making any Restricted Payment (excluding any Restricted Payment described in the preceding
clause (2), (3), (4), (6), (7) or (8)) the Company will deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this
Section 4.07 were computed. For purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the preceding
clauses (1) through (9), or is entitled to be made pursuant to the first paragraph 

  
 38 

 
of this Section 4.07, the Company will be permitted to divide or classify (or later divided or classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in
any manner that complies with this Section 4.07. 
 Section 4.08. Limitation on Dividend and Other Payment Restrictions
Affecting 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 or other obligations owed to the Company or any of its Restricted Subsidiaries; 
 (2) make loans or
advances to the Company or any of its Restricted Subsidiaries; or 
 (3) transfer any of its properties or assets to the
Company or any of its Restricted Subsidiaries. 
 However, the preceding restrictions of this Section 4.08 will not apply to
encumbrances or restrictions existing under or by reason of: 
 (1) agreements governing Existing Indebtedness and Credit
Facilities as in effect on the Original Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements, provided that the amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such encumbrances and restrictions than those contained in those agreements on the
Original Issue Date as determined in good faith by the Company; 
 (2) the Indenture, the Notes and the Subsidiary
Guarantees; 
 (3) Applicable Law; 

(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, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired,
provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of
those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such encumbrances and
restrictions than those contained in those agreements on the date of such acquisition as determined in good faith by the Company; 

  
 39 

 (5) customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices; 
 (6) Capital Lease Obligations or purchase money obligations, in
each case for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in clause (3) of the preceding paragraph; 

(7) any agreement for the sale or other disposition of a Restricted Subsidiary of the Company that restricts distributions
and/or transfers of properties and assets by that Restricted Subsidiary pending its sale or other disposition; 
 (8)
Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements
governing the Indebtedness being refinanced as determined in good faith by the Company; 
 (9) Liens securing Indebtedness
otherwise permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens; 

(10) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale
agreements, stock sale agreements, agreements respecting Permitted Business Investments and other similar agreements entered into (a) in the ordinary course of business or (b) with the Company’s approval by its Board of Directors,
which limitation is applicable only to property or capital stock that are subject to such agreements; 
 (11) restrictions on
cash, Cash Equivalents or other deposits or net worth imposed by customers or suppliers under contracts entered into in the ordinary course of business; 

(12) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business,
not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company and the Restricted Subsidiaries taken
as a whole; and 
 (13) Hedging Obligations permitted to be incurred under the covenants set forth in Section 4.09
hereof. 
 Section 4.09. Limitation on 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”) any Indebtedness (including Acquired Debt), neither the Company nor any Guarantor will issue any
Disqualified Stock, and the Company will not permit any of its other Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company and any Guarantor may incur

  
 40 

 
Indebtedness (including Acquired Debt) or issue Disqualified Stock, if 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 is issued would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma
application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. 

The first paragraph of this Section 4.09 will not prohibit the incurrence of any of the following items of Indebtedness (collectively,
“Permitted Debt”): 
 (1) the incurrence by the Company or any of its Restricted Subsidiaries of additional
Indebtedness (including letters of credit) under one or more 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 Subsidiaries thereunder) not to exceed an amount equal to the greater of (a) $1.25 billion or (b) 30% of ACNTA as of the date of such incurrence; 

(2) the incurrence by the Company or any of its Restricted Subsidiaries of the Existing Indebtedness; 

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes issued and sold on the Issue Date
and the related Subsidiary Guarantees 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 or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to
renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (a) $75.0 million or (b) 1.0% of ACNTA as of the date of such incurrence at any time outstanding;

 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange
for, or the net proceeds of which are used to refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by the Indenture to be incurred under the first paragraph of this Section 4.09, clause (2) or
(3) 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 is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly
subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, or if 

  
 41 

 
a Guarantor is the obligor on such Indebtedness and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash
of all Obligations with respect to the Subsidiary Guarantee of such 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 of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither
the Company nor a Restricted Subsidiary of the Company 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 incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations; 

(8) the guarantee by the Company or any of the Guarantors of Indebtedness of the Company or any Guarantor that was permitted to
be incurred by another provision of this Section 4.09; 
 (9) the incurrence by the Company or any of its Restricted
Subsidiaries of obligations relating to net gas balancing positions arising in the ordinary course of business and consistent with past practice; 

(10) the incurrence by the Company’s Unrestricted Subsidiaries of Non-Recourse Debt, provided, however, that if any
such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event will be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was not permitted by this clause (10); 

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety
and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company and any of its Restricted Subsidiaries with respect to letters of
credit supporting such obligations (in each case other than an obligation for money borrowed); 
 (12) the incurrence by the
Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or
assumed in connection with the disposition of any business, assets or Capital Stock of a Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually
received by the Company and its Restricted Subsidiaries in connection with such disposition; 
 (13) Indebtedness arising
from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided,
however, that such Indebtedness is promptly extinguished; 

  
 42 

 (14) Indebtedness arising in connection with endorsement of instruments for
deposit in the ordinary course of business; 
 (15) Indebtedness owed on a short-term basis to banks and other financial
institutions incurred in the ordinary course of business of the Company and any Restricted Subsidiary with such banks or financial institutions that arises in connection with ordinary banking arrangements to manage cash balances of the Company and
any Restricted Subsidiary; 
 (16) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in
connection with a transaction meeting either of the financial tests set forth in clause (4) under Section 5.01 hereof; and 

(17) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal
amount (or accreted value, as applicable) at any time outstanding, not to exceed the greater of (a) $250.0 million or (b) 2.5% of ACNTA as of the date of incurrence. 

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) meets
the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) above, or is entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company will be permitted to divide
and classify (or later divide, classify, re-divide or reclassify in whole or in part in its sole discretion) such item of Indebtedness in any manner that complies with this covenant, except that any indebtedness under Credit Facilities on the
Original Issue Date (after giving effect to the offering of Existing Senior Notes and the application of the proceeds thereof contemplated by the prospectus relating to such offering) shall be considered incurred under the first paragraph of this
Section 4.09. 
 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, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this
covenant, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed exceeded solely as a result of fluctuations in exchange rates or currency values. 

Section 4.10. Limitation on 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 the Asset Sale at
least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; 

  
 43 

 (2) the fair market value is determined by the Company’s Board of Directors
and evidenced by a resolution of the Board of Directors set forth in an Officers’ Certificate delivered to the Trustee; and 

(3) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of
cash or Cash Equivalents. For purposes of this clause (3) of Section 4.10 only, each of the following will be deemed to be cash or Cash Equivalents: 

(a) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet, of the
Company or any Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a novation agreement that
releases the Company or such Subsidiary from further liability; 
 (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 Subsidiary into cash within 180 days of the receipt thereof, to the extent of the cash received in that conversion; and 

(c) with respect to any Asset Sale of oil and natural gas properties where the Company or such Restricted Subsidiary retains an
interest in such property, the aggregate costs and expenses of the Company or such Restricted Subsidiary related to the exploration, development, completion or production of such properties and activities related thereto which the transferee (or an
Affiliate thereof) agrees to pay. 
 Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any such
Restricted Subsidiary may apply those Net Proceeds at its option to any combination of the following: 
 (I) to prepay, repay, redeem or
repurchase any Indebtedness of the Company or a Guarantor (other than intercompany Indebtedness, Capital Stock or Indebtedness that is subordinated to the Notes or the Subsidiary Guarantees) or any Indebtedness of a Restricted Subsidiary that is not
a Guarantor (other than intercompany Indebtedness); 
 (II) to acquire all or substantially all of the properties or assets of one or more
other Persons primarily engaged in the Oil and Gas Business, and, for this purpose, a division or line of business of a Person shall be treated as a separate Person; 

(III) to acquire a majority of the Voting Stock of one or more other Persons primarily engaged in the Oil and Gas Business; 

(IV) to make one or more capital expenditures; or 

(V) to acquire other long-term assets that are used or useful in the Oil and Gas Business.

 Pending the final application of any Net Proceeds, the Company or any such Restricted Subsidiary
may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by the Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph
will constitute “Excess Proceeds.” 
 On the 361st day after the Asset Sale (or, at the Company’s option, any earlier
date), if the aggregate amount of Excess Proceeds then exceeds $50.0 million, the Company will make an Asset Sale Offer to all Holders of Notes, and to all holders of Pari Passu Indebtedness then outstanding, to purchase the maximum principal amount
of Notes and such Pari Passu Indebtedness that may be purchased out of the Excess Proceeds, pursuant to the terms in Section 3.04 hereof and this Section 4.10. 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 Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, and will
be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and Pari
Passu Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by
the Company so that only Notes in denominations of $2,000 or any integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 

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 the provisions of this
Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions by virtue of such compliance. 

Section 4.11. Limitation on 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 (each,
an “Affiliate Transaction”) involving aggregate consideration in excess of $1.0 million, unless: 
 (1) the
Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person or, if in the good faith judgment of the Company’s Board of 

  
 45 

 
Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted
Subsidiary from a financial point of view; and 
 (2) the Company delivers to the Trustee: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11; and 

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $50.0 million, an Officers’ Certificate certifying that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors. 

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 4.11: 
 (1) any employment, severance or consulting agreement or other compensation
agreement, arrangement or plan, or any amendment thereto, entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business; 

(2) transactions between or among any of the Company and its Restricted Subsidiaries; 

(3) transactions with a Person that is an Affiliate of the Company solely because the Company owns an Equity Interest in such
Person; 
 (4) payment of reasonable directors’ fees, consulting fees and other benefits to persons who are not
otherwise Affiliates of the Company; 
 (5) provision of officers’ and directors’ indemnification and insurance in
the ordinary course of business to the extent permitted by law; 
 (6) sales of Equity Interests (other than Disqualified
Stock) to Affiliates of the Company; 
 (7) Permitted Investments and Restricted Payments that are permitted by
Section 4.07 hereof; 
 (8) any transaction in which the Company or its Restricted Subsidiaries, as the case may be,
deliver to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or its Restricted Subsidiary from a financial point of view or that such transaction
meets the requirements of clause (1) of the initial paragraph above; 
 (9) transactions with Unrestricted Subsidiaries,
Affiliates, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in 

  
 46 

 
each case in the ordinary course of business and otherwise in compliance with the terms of the Indenture which are, in the aggregate (taking into account all the costs and benefits associated
with such transactions) materially no less favorable to the Company or its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated person, in the
good faith determination of the Company’s Board of Directors, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party; and 

(10) transactions between the Company or any of its Restricted Subsidiaries and any Person, a director of which is also a
director of the Company or any direct or indirect parent of the Company; provided, however, that such director abstains from voting as a director of the Company or such direct or indirect parent, as the case may be, on any matter involving
such other Person. 
 Section 4.12. Limitation on Liens. 

The Company will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness or Attributable Debt upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Subsidiary Guarantee of such Restricted
Subsidiary, as applicable, is secured on an equal and ratable basis (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes or such Subsidiary Guarantee, as the case may be) with the obligations so secured
until such time as such obligations are no longer secured by a Lien. 
 Section 4.13. Additional Subsidiary Guarantees. 

If the Company or any of its Restricted Subsidiaries acquires or creates another Material Domestic Subsidiary after the Issue Date, or if any
Restricted Subsidiary that is not already a Guarantor guarantees any other Indebtedness of the Company in a principal amount in excess of $1.0 million after such date, then in either case that Subsidiary will become a Guarantor by executing a
supplemental indenture substantially in the form of Exhibit B hereto and delivering it to the Trustee within 20 Business Days of the date on which it was acquired or created or guaranteed such Indebtedness of the Company, as the case may be,
together with any Opinion of Counsel described in Section 903 of the Original Indenture; provided, however, that (a) the foregoing shall not apply to Subsidiaries of the Company that have properly been designated as Unrestricted
Subsidiaries in accordance with the Indenture for so long as they continue to constitute Unrestricted Subsidiaries, and (b) Whiting Programs, Inc. shall not be required to become a Guarantor unless it guarantees Indebtedness of the Company in a
principal amount in excess of $1.0 million. 
 Section 4.14. Corporate Existence. 

Except as otherwise permitted pursuant to the terms hereof (including consolidation and merger permitted by Section 5.01 hereof), the
Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the
respective organizational documents (as the same may be amended from time to time) of the 

  
 47 

 
Company or any such Restricted Subsidiary; provided, however, that the Company shall not be required to preserve the existence of any of its Restricted Subsidiaries if the Company shall
determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole and that the loss thereof is not adverse in any material respect to the Holders of the
Notes. 
 Section 4.15. Offer to Repurchase Upon Change of Control. 

(1) Within 30 days following the occurrence of a Change of Control, the Company shall make an offer (a “Change of
Control Offer”) to repurchase all or any part (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price (the “Change of Control Payment”) in cash equal to 101% of
the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, thereon to the date of settlement (the “Change of Control Settlement Date”), subject to the right of Holders of record on the relevant
record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Settlement Date. Within 30 days following a Change of Control, the Company shall mail a notice of the Change of Control Offer to each Holder
and the Trustee describing the transaction that constitutes the Change of Control and stating: 
 (a) that the Change of
Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered and not withdrawn will be accepted for payment; 

(b) the purchase price and the Change of Control Settlement Date, which shall be no earlier than 30 days but no later than 60
days from the date such notice is mailed, or in the case of a notice mailed in advance of a Change of Control, no earlier than 30 days and no later than 60 days from the date of such Change of Control; 

(c) that the Change of Control Offer will expire as of the time specified in such notice on the Change of Control Settlement
Date and that the Company shall pay the Change of Control Purchase Price for all Notes purchased as of the Change of Control Settlement Date promptly thereafter on the Change of Control Settlement Date; 

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

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

  
 48 

 (g) that Holders will be entitled to withdraw their election if the Paying Agent
receives, prior to the termination of the Change of Control Offer, 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 its election to have the Notes purchased; 
 (h) that Holders whose Notes are being purchased only in part will
be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or any integral multiple of $1,000 in excess thereof; and 

(i) the Conversion Rate and Conversion Price then in effect and that a Holder that has tendered its Notes for purchase who wishes to withdraw
such Notes and convert them must submit a valid notice of withdrawal and Conversion Notice prior to the close of business on the Business Day immediately preceding the Change of Control Settlement Date. 

If any of the Notes subject to a Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the
extent necessary to accord with the procedures of the Depository applicable to repurchases. Further, the Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this
Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions by virtue of such compliance. 

(2) On the Change of Control Settlement Date, the Company shall, to the extent lawful, accept for payment all Notes or portions
thereof ($2,000 or any integral $1,000 multiple in excess thereof) properly tendered pursuant to the Change of Control Offer. Promptly thereafter on the Change of Control Settlement Date the Company shall: 

(a) deposit with the Paying Agent by 11:00 a.m., New York City time, an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered; and 
 (b) deliver or cause to be delivered to the Trustee the Notes so
accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 

On the Change of Control Settlement Date, the Paying Agent shall mail 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 Depository) and the Trustee shall authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in
principal amount to any unpurchased 

  
 49 

 
portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a principal amount of $2,000 or any integral multiple of $1,000 in excess thereof. The
Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date. 

(c) The Change of Control provisions described above shall be applicable whether or nor any other provisions of the Indenture
are applicable. 
 (d) [Intentionally Omitted.] 

(e) The Company shall not be required to make a Change of Control Offer following a Change of Control (1) if a third party
makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not
withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to Section 3.02 hereof, unless and until there is a default in payment of the applicable Redemption Price. Notwithstanding anything to the
contrary contained herein, a Change of Control Offer by the Company or a third party may be made in advance of a Change of Control, and conditioned upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of
Control at the time the Change of Control Offer is made. 
 (3) In the event that Holders of Notes of not less than 90% of the aggregate
principal amount of the outstanding Notes accept a Change of Control Offer and the Company 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 the purchase pursuant to the Chang of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at a purchase price equal to the Change of Control Payment plus, to the extent not included in the
Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, if any, to the Change of Control Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an
interest payment date that is on or prior to the Change of Control Settlement Date. Any such redemption shall be effected in accordance with Article Eleven of the Original Indenture; provided that any notice of redemption sent in respect of
such redemption shall state, in addition to the requirements of Section 1104 of the Original Indenture, the Conversion Rate and Conversion Price in effect on the date of the notice of redemption and that a Holder who elects to convert all or a
portion of its Notes in lieu of redemption must submit a Conversion Notice with respect to such Notes being converted on or before the close of business on the Business Day immediately preceding the Redemption Date. 

  
 50 

 Section 4.16. No Inducements. 

The Company shall not, and the Company shall not permit any of its Subsidiaries, either directly or indirectly, to pay (or cause to be paid)
any consideration, whether by way of interest, fee or otherwise, to any Beneficial Owner or Holder of the Notes for or as an inducement to any consent to any waiver, amendment or supplement of any terms or provisions of the Indenture or the Notes,
unless such consideration is offered to be paid (or agreed to be paid) to all Beneficial Owners and Holders of the Notes which so consent in the time frame set forth in the solicitation documents relating to such consent. 

Section 4.17. Designation of Restricted and Unrestricted Subsidiaries. 

The Board of Directors of the Company may designate any Restricted Subsidiary of the Company to be an Unrestricted Subsidiary if that
designation would not cause a Default. If a Restricted Subsidiary of the Company 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 properly designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 hereof or represent Permitted
Investments, as determined by the Company. That designation shall only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary. 

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company;
provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if
(1) such Indebtedness is permitted under Section 4.09 hereof, 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. 
 Section 4.18. Covenant Termination. 

If at any time (a) the rating assigned to the Notes by both S&P and Moody’s is an Investment Grade Rating and (b) no
Default has occurred and is continuing under this Indenture, then upon delivery by the Company to the Trustee of an Officers’ Certificate to the foregoing effect, the Company and its Restricted Subsidiaries will no longer be subject to the
following provisions of this Indenture: Sections 4.07, 4.08, 4.09, 4.10 or 4.11 or clause (d) of Section 5.01. The Company and its Restricted Subsidiaries will remain subject to all other provisions of the Indenture. 

Section 4.19. Calculation of Original Issue Discount. 

The Company shall file with the Trustee promptly after the end of each calendar year for which reporting on Form 1099 OID is required
(i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Notes as of the end of such year and (ii) such other specific information relating to such original
issue discount as may then be required to be provided to the Trustee or the holders of the Notes 

  
 51 

 
pursuant to the Code, and the regulations issued thereunder; provided, however, that no notice shall be required hereunder in the event that there are no Outstanding Notes as of the
end of said calendar year. 
 ARTICLE 5 

SUCCESSORS 
 The provisions of
Article Eight of the Original Indenture shall not apply to the Notes, and in lieu thereof the following provisions of this Article 5 shall apply to the Notes. 

Section 5.01. Merger, Consolidation, or Sale of Assets. 

The Company shall not, directly or indirectly, (1) consolidate or merge with or into another Person (whether or not the Company is the
surviving entity), or (2) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole, in one or more related transactions
to, another Person, unless: 
 (a) either (1) the Company is the surviving corporation or (2) the Person
formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is an entity organized or existing under the laws of the
United States, any state of the United States or the District of Columbia; provided that if the Company or such other Person is not a corporation, a Restricted Subsidiary of the Company that is a corporation shall assume by supplemental
indenture all obligations of the Company under the Notes and the Indenture as a co-issuer of the Notes; 
 (b) the
Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company
under the Notes and the Indenture pursuant to a supplemental indenture or other agreement in a form reasonably satisfactory to the Trustee; 

(c) immediately after such transaction no Default or Event of Default exists; 

(d) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which
such sale, assignment, transfer, lease, conveyance or other disposition shall have been made will, at the time of such transaction and after giving pro forma effect thereto and any related financing transaction as if the same had occurred at the
beginning of the applicable four-quarter period, either (a) be 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 4.09 hereof or
(b) have a Fixed Charge Coverage Ratio that is equal to or greater than the Fixed Charge Coverage Ratio of the Company immediately prior to such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition; and 

(e) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that
such consolidation, merger, sale, assignment, transfer, lease, conveyance or disposition and such supplemental indenture (if any) comply with the Indenture; 

  
 52 

 provided, however, that (i) this Section 5.01 shall not apply to any sale, assignment, transfer,
lease, conveyance or other disposition of assets between or among the Company and its Restricted Subsidiaries and (ii) clauses (c) and (d) hereof shall not apply to any merger or consolidation of the Company (I) with or into one
of its Restricted Subsidiaries for any purpose or (II) with or into an Affiliate solely for the purpose of reincorporation of the Company in another jurisdiction. 

Section 5.02. Successor Entity Substituted. 

Upon any consolidation or merger, or any sale, assignment, transfer, lease, 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 in accordance with Section 5.01 hereof, the successor entity formed by such consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor entity had been named as the Company herein
and shall be substituted for the Company (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of the Indenture referring to the “Company” shall
refer instead to the successor entity and not to the Company); and thereafter, if the Company is dissolved following a transfer of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole
in accordance with the Indenture, the Company shall be discharged and released from all obligations and covenants under the Indenture and the Notes. The Trustee, the Company and the successor Person shall enter into a supplemental indenture to
evidence the succession and substitution of such successor Person and such discharge and release of the Company. 
 ARTICLE 6 

DEFAULTS AND REMEDIES 

Section 6.01. Events of Default. 

In accordance with Section 301(19) of the Original Indenture, Section 501 of the Original Indenture is hereby amended to read in its
entirety as follows with respect to the Notes: 
 “An ‘Event of Default’ occurs if one of the following shall have occurred
and be continuing (whatever the reason for such Event of Default and whether it shall be involuntary or be effected by operation of law): 

(1) the Company defaults in the payment when due of interest with respect to the Notes, and such default continues for a period
of 30 days; 
 (2) the Company defaults in the payment of the principal of or premium, if any, on the Notes when due at its
Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; 

  
 53 

 (3) the Company fails to comply with the provisions of Section 4.07, 4.09,
4.10, 4.15 or 5.01 of the First Supplemental Indenture; 
 (4) the Company or a Guarantor fails to comply with any other
covenant or other agreement in the Indenture or the Notes for 60 days (or 180 days in the case of a Reporting Failure) after notice to the Company by the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding of
such failure; 
 (5) a default occurs under any mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or
guarantee now exists or is created after the Issue Date, if such 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 any grace period provided in such Indebtedness (a “Payment Default”); or 

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

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which
there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or more; provided, that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within
a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default under the Indenture and any consequential acceleration of the Notes shall
be automatically rescinded; 
 (6) the Company or any of its Significant Subsidiaries fails to pay final judgments
aggregating in excess of $50.0 million, which judgments are not paid, discharged or stayed (including a stay pending appeal) for a period of 60 days after the date of such final judgment (or, if later, the date when payment is due pursuant to such
judgment); 
 (7) except as permitted by this Indenture, any Subsidiary Guarantee is held in any judicial proceeding to be
unenforceable or invalid or ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee (other than by reason of release
of a Guarantor from its Subsidiary Guarantee in accordance with the terms of the Indenture); 
 (8) the Company, any
Significant Subsidiary of the Company or any group of Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law: 

(a) commences a voluntary case, 

  
 54 

 (b) consents in writing to the entry of an order for relief against it in an
involuntary case, 
 (c) consents in writing to the appointment of a Custodian of it or for all or substantially all of its
property, 
 (d) makes a general assignment for the benefit of its creditors, or 

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

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

(a) is for relief against the Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the Company
that, taken together, would constitute a Significant Subsidiary in an involuntary case; 
 (b) appoints a Custodian of the
Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company, any Significant Subsidiary
of the Company or any group of Subsidiaries of the Company, that, taken together, would constitute a Significant Subsidiary; or 

(c) orders the liquidation of the Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the
Company that, taken together, would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60
consecutive days; or 
 (10) the Company fails to satisfy its conversion or payment obligations in accordance with Article 11
(x) upon a Holder’s exercise of its Early Conversion rights or (y) upon the Company’s exercise of its Mandatory Conversion rights, which failure in each case is not cured within five Business Days.” 

Section 6.02. Acceleration. 

Also as permitted by Section 301(19) of the Original Indenture, the first paragraph of Section 502 of the Original Indenture is
hereby amended to read in its entirety as follows with respect to the Notes: 
 “If any Event of Default occurs and is continuing, the
Trustee, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Upon any such
declaration, the Notes shall become due and payable immediately, together with all accrued and unpaid interest and premium, if any, thereon. Notwithstanding the preceding, if an Event of Default specified in clause (8) or (9) of
Section 501 hereof occurs with 

  
 55 

 
respect to the Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding
Notes shall become due and payable without further action or notice, together with all accrued and unpaid interest and premium, if any, thereon.” 

Section 6.03. Waiver of Past Defaults. 

Section 513 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes: 

The Holders of not less than a majority in principal amount of the outstanding Notes may on behalf of the Holders of all Notes waive any past
default hereunder with respect to the Notes and its consequences, except a default 
 (1) in the payment of the principal of
or any premium or interest on the Notes or settlements due upon the conversion of 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
this Indenture), or 
 (2) in respect of a covenant or provision hereof which under Section 9.02 of the First
Supplemental Indenture cannot be modified or amended without the consent of each Holder of the Notes. 
 Upon any such waiver, such default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 6.04. Waiver of Usury, Stay or Extension of Laws. 

Section 515 of the Original Indenture shall not apply to the Notes inasmuch as it is duplicative of Section 4.06 of this First
Supplemental Indenture. 
 ARTICLE 7 

TRUSTEE; REPORTS 

Section 7.01. Notice of Defaults. 

With respect to the Notes only, the proviso in the first sentence of Section 602 of the Original Indenture shall be deemed inapplicable.

Section 7.03. Compensation and Reimbursement. 

With respect to the Notes only, Section 607 of the Original Indenture is hereby amended to include the following: 

As security for the performance of the obligations of the Company under this Section the Trustee shall have a lien prior to the Notes upon all
property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (and premium, if any) or interest on particular Notes. 

  
 56 

 In addition to, but without prejudice to its other rights under this Indenture, when the Trustee
incurs expenses or renders services in connection with an Event of Default specified in Sections 501(8) or 501(9) of the Original Indenture (as amended by Section 6.01 of the First Supplemental Indenture), the expenses (including the reasonable
charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. 

“Trustee” for purposes of this Section shall include any predecessor Trustee. 

The provisions of this Section shall survive the satisfaction and discharge of the Notes, the termination for any reason of this Indenture,
and the resignation or removal of the Trustee. 
 Section 7.04. Reports by Company and Subsidiary Guarantors. 

Section 704 of the Original Indenture shall not apply to the Notes inasmuch as its requirements are duplicative of those set forth in
Section 4.03(a) of this First Supplemental Indenture.

 ARTICLE 9 
 AMENDMENT,
SUPPLEMENT AND WAIVER 
 Section 9.01. Without Consent of Holders of Notes. 

Section 901 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes: 

“Notwithstanding Section 902 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture,
the Notes or the Subsidiary Guarantees without the consent of any Holder of a Note: 
 (1) to cure any ambiguity, defect or

change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder, including any increase in the Conversion Rate or other consideration due upon
conversion of the Notes (whether or not subject to time limitations or other conditions); provided that a change to this Indenture, the Notes or the Subsidiary Guarantees shall not be deemed to adversely affect the legal rights hereunder of
any Holder if (A) such change is to conform a provision of this Indenture, the Notes or the Subsidiary Guarantees (a “Note Provision”) to a provision in the Existing Senior Notes Prospectus (an “Existing Senior Notes
Prospectus Provision”), (B) such Existing Senior Notes Prospectus Provision was intended to be a verbatim recitation of a provision in the Existing Senior Notes Indenture (an “Existing Senior Notes Indenture
Provision”) and (C) such Note Provision is intended to be identical to such Existing Senior Notes Indenture Provision; 

(5) to secure the Notes or the Subsidiary Guarantees pursuant to the requirements of Section 4.12 of the First
Supplemental Indenture or otherwise;

(ii) modify the rights of the Holder of any such Security with respect to such provision or (B) shall become effective only when there is no such Security Outstanding; 

(11) to establish the form or terms of Securities of any series as permitted by Sections 201 and 301; or

 59 

 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing
the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the Opinion of Counsel described in Section 903 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended
or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or
supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.” 
 Section 9.02.
With Consent of Holders of Notes. 
 Section 902 of the Original Indenture is hereby amended to read in its entirety as follows
with respect to the Notes: 
 “Except as provided above in Section 901 and below in this Section 902, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Subsidiary Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including consents obtained
in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 508 and 513 hereof, any existing Default or Event of Default with respect to the Notes or compliance with any provision of this Indenture, the
Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, tender offer or
exchange offer for Notes). 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the Opinion of Counsel
described in Section 903 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 

It shall not be necessary for the consent of the Holders of Notes under this Section 902 to approve the particular form of any proposed
amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment,
supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 508 and 513 hereof and to the last paragraph of this Section 902, the Holders of a majority in
principal amount of the Notes then 

  
 60 

 
outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment,
supplement or waiver may not (with respect to any Notes held by a non-consenting Holder): 
 (a) reduce the principal amount of Notes whose
Holders must consent to an amendment, supplement or waiver; 
 (b) reduce the principal of or change the fixed maturity of any Note or alter
any of the provisions with respect to the redemption or repurchase of the Notes (except as provided in Sections 3.04, 4.10 and 4.15 of the First Supplemental Indenture); 

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

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

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

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or Events of Default or the rights of Holders of
Notes to receive payments of principal of or premium, if any, or interest on the Notes (except as permitted in clause (g) below) or settlements due upon conversion of the Notes; 

(g) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 3.04, 4.10 and 4.15 of the
First Supplemental Indenture); 
 (h) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture,
except in accordance with the terms of this Indenture; 
 (i) reduce the consideration due upon conversion or otherwise adversely affect the
right of Holders to convert Notes in accordance with Article 11 of the First Supplemental Indenture or modify the Mandatory Conversion provisions of the First Supplemental Indenture in a manner adverse to Holders; or 

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

Section 9.03. Revocation and Effect of Consents. 

A consent to any amendment, supplement or waiver under the Indenture by any Holder given in connection with a purchase, tender or exchange of
such Holder’s Notes shall not be rendered invalid by such purchase, tender or exchange. 
 Until an amendment, supplement or waiver
becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if

  
 61 

 
notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of
revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons,
shall be entitled to consent to such amendment or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such
record date except to the extent that the requisite number of consents to the amendment, supplement or waiver have been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.03. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses
(a) through (i) of Section 902 of the Indenture, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that
evidences the same indebtedness as the consenting Holder’s Note. 
 ARTICLE 10 

GUARANTEES OF NOTES 
 The Notes
shall have the benefit of Subsidiary Guarantees. The provisions of Article Thirteen of the Original Indenture shall not apply to the Notes, and in lieu thereof the following provisions of this Article 10 shall apply to the Notes. 

Section 10.01. Subsidiary Guarantees. 

Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this First Supplemental Indenture or the Indenture, the Notes held thereby and the Obligations of the
Company hereunder and thereunder, that: (a) the principal of and premium, if any, and interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon
repurchase or redemption or otherwise, and interest on the overdue principal of and premium, if any, and (to the extent permitted by law) interest on the Notes, and all other payment Obligations of the Company to the Holders or the Trustee hereunder
or thereunder will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be
promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise. Failing payment
when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. An Event of 

  
 62 

 
Default with respect to the Notes under the Indenture shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the
Guarantors hereunder in the same manner and to the same extent as the Obligations of the Company. 
 The Guarantors hereby agree that their
obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this First Supplemental Indenture or the Indenture, the absence of any action to enforce the same, any waiver or consent by any
Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company,
any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and
the Indenture. 
 If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any
Custodian, Trustee or other similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged,
shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to, and hereby waives, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby. 

Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand,
(a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Five of the Original Indenture for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article Five of the Original Indenture, such Obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not
impair the rights of the Holders under the Subsidiary Guarantees. 
 Section 10.02. Notation of Subsidiary Guarantees. 

The Subsidiary Guarantees shall be evidenced by the execution and delivery of the First Supplemental Indenture or a supplement to the
Indenture and no notation of any Subsidiary Guarantee need be endorsed on any Note, notwithstanding any contrary provision of the Original Indenture. 

Section 10.03. Guarantors May Consolidate, Etc., on Certain Terms. 

(a) No Guarantor shall sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with
or into (whether or not such Guarantor is the surviving Person), another Person (other than the Company or another 

  
 63 

 
Guarantor), unless, (i) either (1) 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 Guarantor) unconditionally assumes all the obligations of such Guarantor, pursuant to a supplemental indenture, substantially in the form of Exhibit B hereto, under the Notes, the Indenture and its Subsidiary
Guarantee on terms set forth therein, or (2) the Net Proceeds of such sale or other disposition are applied in accordance with the provisions of Section 4.10 hereof, and (ii) immediately after giving effect to such transaction, no
Default or Event of Default exists. 
 (b) In the case of any such consolidation or merger and upon the assumption by the successor Person,
by supplemental indenture, executed and delivered to the Trustee and substantially in the form of Exhibit B hereto, of the Subsidiary Guarantee and the due and punctual performance of all of the covenants of the Indenture to be performed by the
Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. 

Section 10.04. Releases of Subsidiary Guarantees. 

The Subsidiary Guarantee of a Guarantor shall be released: (1) in connection with any sale or other disposition of all or substantially
all of the properties or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company, if the sale or other disposition complies
with Section 4.10 hereof; or (2) in connection with any sale or other disposition of all of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company,
if the sale or other disposition complies with Section 4.10 hereof; or (3) if such Guarantor ceases to be a Material Domestic Subsidiary and is not a guarantor of Indebtedness of the Company in excess of $1.0 million; or (4) if the
Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of the Indenture; or (5) upon Discharge in accordance with Article 8 hereof. 

Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any of the foregoing clauses (1) –
(5) has occurred, the Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations
under its Subsidiary Guarantee shall remain liable for the full amount of principal of, premium, if any, and interest on the Notes and for the other obligations of such Guarantor under the Indenture as provided in this Article 10. 

Section 10.05. Limitation on Guarantor Liability. 

The obligations of each Guarantor under its Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all
other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee or
pursuant to its contribution obligations under the Indenture, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise
being void or voidable under any similar laws affecting the rights of creditors generally. 

  
 64 

 Section 10.06. “Trustee” to Include Paying Agent. 

In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term
“Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such
Paying Agent were named in this Article 10 in place of the Trustee. 
 ARTICLE 11 

CONVERSION 
 Section 11.01.
Conversion. (a) Subject to compliance with Section 11.02, a Holder shall have the right to convert all or any portion (if such portion is $2,000 principal amount or an integral multiple of $1,000 principal amount) of its Notes
(“Early Conversion”) at any time and from time to time, on any Business Day, prior to the earliest of (i) if applicable, the close of business on the fifth Business Day following the date of a Mandatory Conversion Notice
delivered in accordance with Section 11.01(b), (ii) if applicable, with respect to a Note called for redemption, the close of business on the Business Day immediately preceding the Redemption Date or (iii) the close of business on the
Business Day immediately preceding the maturity date, into a number of shares of Common Stock per $1,000 principal amount of Notes being converted equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares of Common Stock in
accordance with Section 11.03). In addition, upon an Early Conversion, a Holder shall have the right to receive in cash, with respect to its Notes being converted, per $1,000 principal amount of Notes being converted, (x) in the event the
Early Conversion Date occurs on or prior to September 23, 2017, the Early Conversion Payment and (y) in all cases, accrued and unpaid interest to the Early Conversion Date. For the avoidance of doubt, in the event of an Early Conversion
with an Early Conversion Date after September 23, 2017, Holders shall not be entitled to receive the Early Conversion Payment. 

(b) The Company shall have the right to convert the Notes (“Mandatory Conversion”), in whole or in part, into a number
of shares of Common Stock per $1,000 principal amount of Notes equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares of Common Stock in accordance with Section 11.03), if each of the following conditions are
satisfied: (i) the VWAP of the Common Stock (or other security into which the Notes are convertible pursuant to Section 11.11) exceeds the Threshold Price in effect on each applicable Trading Day for at least 20 Trading Days (whether or
not consecutive) during any period of 30 consecutive Trading Days (the “VWAP Condition”) and (ii) the Company delivers to the Holders, the Trustee and the Conversion Agent (if other than the Trustee) a notice of the
Company’s election of its right to convert the Notes no later than the open of business on the third Business Day immediately following the 20th Trading Day of any such 30 Trading Day period
(a “Mandatory Conversion Notice”), which notice shall specify that the Mandatory Conversion shall occur on the sixth Business Day following the date of such notice (the “Mandatory Conversion Date”); provided
that, the Company’s right to cause a Mandatory Conversion shall be suspended during the period beginning on the date a Change of Control Offer is made and continuing to, and including, the applicable Change of Control Settlement Date. For
the avoidance of doubt, in the event of a Mandatory Conversion, Holders shall not be entitled to receive the Early Conversion Payment or, except as provided in Section 11.02(f), accrued and unpaid interest. The Mandatory Conversion Notice shall
state that the Company is exercising its right to cause a Mandatory Conversion, the Conversion Rate and Conversion Price in effect on the Mandatory Conversion Date. 

  
 65 

 Notwithstanding the foregoing, the Company may only exercise its right to cause a
Mandatory Conversion if, as evidenced by an Officers’ Certificate delivered to the Trustee and the Conversion Agent (if other than the Trustee) on the Mandatory Conversion Date, all of the conditions listed below (the “Equity
Conditions”) are satisfied on each day during the period (x) commencing on, and including, the date of the Mandatory Conversion Notice and (y) ending on, and including, the Mandatory Conversion Date (the “Equity Conditions
Measuring Period”). The Equity Conditions are as follows: 
 (i) either (1) all shares of Common Stock issuable upon
conversion of the Notes and held by a non-Affiliate of the Company shall be eligible for sale without the need for registration under any applicable federal or state securities laws or (2) a shelf registration statement registering the resale
of the shares of Common Stock issuable upon conversion of the Notes has been filed by the Company and been declared effective by the SEC or is automatically effective and is available for use, and the Company expects such shelf registration
statement to remain effective and available for use from the Mandatory Conversion Date until thirty days following the Mandatory Conversion Date; 

(ii) the Common Stock (or other security into which the Notes are convertible pursuant to Section 11.11) to be delivered on such
conversion is listed or traded on The New York Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market, The NASDAQ Capital Market, or any of their respective successors (each, an “Eligible Market”) and shall not
then be suspended from trading on such Eligible Market; 
 (iii) at or prior to the settlement date of the Mandatory Conversion, for
any Notes validly surrendered for conversion with an Early Conversion Date prior to the Mandatory Conversion Date in accordance with the terms of this Indenture, the Company shall have delivered and paid the number of shares of Common Stock and the
amount of cash due upon conversion of the Notes to the Holders in accordance with Section 11.01(a); 
 (iv) shares of Common Stock to
be issued upon conversion may be issued in full without violating the rules or regulations of The New York Stock Exchange or any other applicable Eligible Market on which the Common Stock delivered upon conversion is then listed or trading; and 

(v) no Event of Default shall have occurred and be continuing. 

For the avoidance of doubt, the Company may exercise its right to cause more than one Mandatory Conversion so long as any Notes are
outstanding so long as it complies with the other requirements of this Section 11.01(b). If the Company exercises its right to cause Mandatory Conversion in part, the Conversion Agent will select the Notes to be converted pro rata, by lot or by
any other method the Conversion Agent in its sole discretion deems fair and appropriate (or, in the case of Notes represented by Global Notes, in such manner as DTC may require), in denominations of $2,000 or any integral $1,000 multiple in excess
thereof. 

  
 66 

 Section 11.02. Conversion Procedure and Payment Upon Conversion. 

(a) To convert its Note pursuant to an Early Conversion, a Holder of a definitive Note must: 

(1) complete and manually sign the Conversion Notice, with appropriate signature guarantee, or facsimile of the Conversion
Notice and deliver the completed Conversion Notice (which shall be irrevocable) to the Conversion Agent; 
 (2) surrender the
Note to the Conversion Agent; 
 (3) furnish appropriate endorsements and transfer documents if required by the Security
Registrar or Conversion Agent; 
 (4) pay all transfer or similar taxes if required pursuant to Section 11.04; and 

(5) pay funds equal to interest payable on the next Interest Payment Date required by Section 11.02(e). 

If a Holder holds a beneficial interest in a Note that is a Global Security (a “Global Note”), to convert such
Note, the Holder must comply with clauses (4) and (5) above and the Depositary’s procedures for converting a beneficial interest in a Global Note. 

(b) (i) Upon conversion of a Holder’s Note in an Early Conversion, the Company shall deliver to such converting Holder, through the
Conversion Agent, a number of shares of Common Stock per $1,000 principal amount of Notes being converted equal to the Conversion Rate in effect on the applicable Early Conversion Date (plus cash in lieu of fractional shares in accordance with
Section 11.03). In addition, the Company shall deliver, through the Conversion Agent, with respect to the Notes being converted, cash in an amount per $1,000 principal amount of Notes equal to the Early Conversion Payment, if owed pursuant to
Section 11.01(a), and accrued and unpaid interest to the Early Conversion Date. If a Holder converts more than one Note at the same time, the full number of shares of Common Stock issued upon such conversion (and, as a result, the amount of
cash deliverable in lieu of any fractional share of Common Stock) and the amount of cash deliverable in respect of the Early Conversion Payment, if owed pursuant to Section 11.01(a), and accrued and unpaid interest shall be based on the
aggregate principal amount of Notes converted by such Holder. Settlement shall occur on the third Business Day immediately following the applicable Early Conversion Date. 

(1) Upon conversion of the Notes in a Mandatory Conversion, the Company shall deliver to each Holder, through the Conversion
Agent, a number of shares of Common Stock per $1,000 principal amount of Notes equal to the Conversion Rate in effect on the Mandatory Conversion Date (plus cash in lieu of fractional shares in accordance with Section 11.03). The full number of
shares of Common Stock issued upon such conversion (and, as a result, the amount of cash deliverable in lieu of any fractional share of Common Stock) shall be based on the aggregate principal amount of Notes outstanding. Settlement shall occur on
the third Business Day immediately following the Mandatory Conversion Date. 
 (2) The shares of Common Stock due upon
conversion of a Global Note shall be delivered by the Company in accordance with the Depositary’s customary practices. 

  
 67 

 (c) Notes surrendered for conversion will be deemed converted at the close of business on the
applicable Conversion Date, and the Person in whose name the shares of Common Stock shall be issued upon such conversion shall become the holder of record of such shares as of the close of business on such Conversion Date. Prior to such time, a
Holder receiving shares of Common Stock upon conversion shall not be entitled to any rights relating to such shares of Common Stock, including, among other things, the right to vote, tender in a tender offer and receive dividends and notices of
shareholder meetings. On and after the close of business on the applicable Conversion Date with respect to a conversion of a Note pursuant hereto, all rights of the Holder of such Note shall terminate, other than the right to receive the
consideration deliverable or payable upon conversion of such Note as provided in Section 11.02(b). 
 (d) Except as provided in this
Article 11, no payment or other adjustment will be made for accrued interest on any Notes converted, and accrued interest, if any, will be deemed to be paid by the consideration paid to the Holder upon conversion. Such accrued interest, if any,
shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. 
 (e) If any Holder surrenders a Note for Early
Conversion after the close of business on the Regular Record Date but prior to the open of business on the next Interest Payment Date, then, notwithstanding such conversion, the full amount of interest payable with respect to such Note on such
Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Note at the close of business on such Regular Record Date; provided, however, that such Note, when surrendered for conversion, must be
accompanied by payment in cash to the Conversion Agent of an amount equal to the full amount of interest payable on such Interest Payment Date on the Note so converted. For the avoidance of doubt, in accordance with Section 11.01(a), such
converting Holder shall be entitled to receive accrued and unpaid interest to the Early Conversion Date and such amount of cash shall be delivered to such converting Holder in accordance with Section 11.02(b)(i). 

(f) In the event a Mandatory Conversion Date falls after the close of business on the Regular Record Date but prior to the open of business on
the next Interest Payment Date, then, notwithstanding such conversion, the full amount of interest payable with respect to such Note on such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Note at
the close of business on such Regular Record Date. In such event, the Holders shall be entitled to retain the full amount of interest payable on such Interest Payment Date. 

(g) Upon surrender of a Note that is converted in part, the Trustee shall authenticate for the Holder a new Note equal in principal amount to
the unconverted portion of the Note surrendered. 

  
 68 

 Section 11.03. Cash in Lieu of Fractional Shares. The Company will not issue a
fractional share of Common Stock upon conversion of a Note. Instead, the Company shall pay cash in lieu of fractional shares based on the VWAP of the Common Stock on the applicable Conversion Date (or, if such Conversion Date is not a Trading Day,
the VWAP of the Common Stock on the Trading Day immediately preceding such Conversion Date). 
 Section 11.04. Taxes on
Conversion. The Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of Common Stock upon the conversion of a Note. However, such Holder shall pay any such tax or duty that is due because
such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver a certificate representing the Common Stock to be issued in a name other than such Holder’s name until the Conversion Agent receives
a sum sufficient to pay any tax or duty which will be due because such shares are to be issued in a name other than such Holder’s name. 

Section 11.05. Company to Reserve, Provide and List Common Stock. The Company shall at all times reserve out of its authorized but
unissued Common Stock or Common Stock held in its treasury a sufficient number of shares of Common Stock to permit the conversion, in accordance herewith, of all of the Notes (assuming, for such purposes, that at the time of computation of such
number of shares, all such Notes would be converted by a single Holder). 
 All shares of Common Stock issued upon conversion of the Notes
shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company. 

The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Notes and
shall list such shares on each national securities exchange or automated quotation system on which the shares of Common Stock are listed on the applicable Conversion Date. 

Section 11.06. Adjustment of Conversion Rate. The Conversion Rate shall be subject to adjustment from time to time, without
duplication, upon the occurrence of any of the following events: 
 (a) If the Company issues shares of Common Stock as a dividend or
distribution on all shares of the Common Stock, or if the Company effects a share split or share combination (including a “reverse split”), the Conversion Rate shall be adjusted based on the following formula: 

 

									
	CR’	  	=	  	CR0	  	x	  	OS’
	  	  	  	  	  

	  	  	  	  	OS0

  

			
	where,	  	
		
	CR0 =	  	the Conversion Rate in effect immediately prior to the close of business on the record date for such dividend or distribution, or immediately prior to open of business on the effective date of such share split or share combination,
as the case may be;

  
 69 

			
	CR’ =	  	the Conversion Rate in effect immediately after the close of business on the record date for such dividend or distribution, or immediately after the open of business on the effective date of such share split or share combination, as
the case may be;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the record date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split
or share combination, as the case may be; and
		
	OS’ =	  	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or such share split or share combination, as the case may be.

 Any adjustment made under this Section 11.06(a) shall become effective immediately after the close of
business on the record date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in
this Section 11.06(a) is declared but not so paid or made, then the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate
that would then be in effect if such dividend or distribution had not been declared. 
 (b) In addition to the foregoing adjustments in
subsection (a) above, the Company may, from time to time and to the extent permitted by law, increase the Conversion Rate by any amount for a period of at least 20 Business Days or any longer period as may be permitted or required by law, if
the Board of Directors has made a determination, which determination shall be conclusive, that such increase would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give
notice to the Trustee and cause notice of such increase to be mailed to each Holder of Notes at such Holder’s address as the same appears on the registry books of the Security Registrar at least 15 days prior to the date on which such increase
commences. 
 (c) All calculations under this Article 11 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the
case may be. Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th. 

  
 70 

 Section 11.07. No Adjustment. The Conversion Rate shall not be adjusted for any
transaction or event other than as specified in this Article 11. 
 Section 11.08. Adjustments for Tax Purposes. Except as
prohibited by law, the Company may (but is not obligated to) increase the Conversion Rate, in addition to those required by Section 11.06 hereof, as it determines to be advisable in order that any dividend, distribution, share split or share
combination will not be taxable to the recipients thereof or in order to avoid or diminish any such taxation. 
 Section 11.09.
Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Security Registrar’s books a notice of the adjustment and file with the Trustee and the
Conversion Agent an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness of such adjustment. 

Section 11.10. Notice of Certain Transactions. In the event that: 

(a) the Company takes any action that would require an adjustment in the Conversion Rate, 

(b) the Company takes any action that would require a supplemental indenture pursuant to Section 11.11, or 

(c) there is a dissolution or liquidation of the Company, 

the Company shall promptly mail to Holders at the addresses appearing on the Registrar’s books and the Trustee a written notice stating the proposed
record date and effective date of the transaction referred to in clause (a), (b) or (c) of this Section 11.10. 

Section 11.11. Effect of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege. If
the Company: 
 (a) reclassifies the Common Stock (other than a change only in par value, or from par value to no par value, or from no par
value to par value, or a change as a result of a subdivision or combination of Common Stock to which Section 11.06(a) applies); 
 (b)
is party to a consolidation, merger or binding share exchange; or 
 (c) sells, transfers, leases, conveys or otherwise disposes of all or
substantially all of the consolidated property or assets of the Company, 
 in each case, pursuant to which the Common Stock would be converted into
or exchanged for, or would constitute solely the right to receive, cash, securities or other property (any such event, a “Merger Event”), each $1,000 principal amount of Notes will, from and after the effective time of such Merger
Event, in lieu of being convertible into Common Stock, be convertible into the same kind, type and proportions of consideration that a holder of a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to such
Merger Event would have received in such Merger Event (“Reference Property”) and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture providing for such change in the right to convert the Notes.  

  
 71 

 If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to
receive more than a single type of consideration (determined based in part upon any form of stockholder election), then: 
 (i) the
Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; and 

(ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause
(i) attributable to one share of Common Stock. 
 The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of
such weighted average as soon as practicable after such determination is made. 
 The supplemental indenture referred to in the first
sentence of this Section 11.11 shall, in the good faith judgment of the Company as evidenced by an Officers’ Certificate, (i) provide for adjustments to the Conversion Rate that shall be as nearly equivalent as may be practicable to
the adjustments of the Conversion Rate provided for in this Article 11 and for the delivery of cash by the Company in lieu of fractional securities or property that would otherwise be deliverable to Holders upon conversion as part of the Reference
Property, with such amount of cash determined by the Company in a manner as nearly equivalent as may be practicable to that used by the Company to determine the VWAP of the Common Stock and (ii) provide that after the Merger Event, the VWAP
Condition (and related calculations) shall be determined with reference to the trading value of the Reference Property as determined in good faith by the Company in a manner as nearly equivalent as may be practicable to that used by the Company to
determine the VWAP of the Common Stock. If the Reference Property includes shares of stock, other securities or other property or assets (including any combination thereof) of a company other than the Company or the successor or purchasing entity,
as the case may be, in such Merger Event, then such other company shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the right
of Holders to require the Company to repurchase their Notes upon a Change of Control in accordance with Section 4.15, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this
Section 11.11 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions. 

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 11.11. 

None of the foregoing provisions shall affect the right of a Holder to convert its Notes into shares of Common Stock (and cash in lieu of any
fractional share) as set forth in Section 11.01(a) and Section 11.02 prior to the effective date of such Merger Event, or the right of the Company to effect a Mandatory Conversion in accordance with Section 11.01(b). 

  
 72 

 In the event the Company shall execute a supplemental indenture pursuant to this
Section 11.11, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Notes upon the conversion of their Notes
after any such Merger Event and any adjustment to be made with respect thereto. 
 Section 11.12. Notice to Holders. The Company
shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder at its address appearing on the applicable Security Register a copy of any notice sent to the holders of the Company’s 1.25% Convertible Senior
Notes due 2020 (the “Existing 2020 Convertible Notes”) pursuant to Section 14.10 of the Indenture dated as of March 27, 2015 (as amended, the “Existing 2020 Convertible Notes Indenture”) among the Company,
the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as Trustee, as soon as practicable after such notice is sent to such holders; provided that in the event the Existing 2020 Convertible Notes are repaid,
prepaid, redeemed, defeased, retired or otherwise cease to exist, then the Company shall mail to each Holder at its address appearing on the applicable Security Register any notices that would have been required to be sent to the holders of the
Existing 2020 Convertible Notes pursuant to Section 14.10 of the Existing 2020 Convertible Notes Indenture were the Existing 2020 Convertible Notes still outstanding. 

Section 11.13. Trustee’s Disclaimer. Neither the Trustee nor the Conversion Agent shall have any duty to determine when an
adjustment under this Article 11 should be made, how it should be made or what such adjustment should be, but the Trustee and the Conversion Agent may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in
relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee and the Conversion Agent pursuant to Section 11.09 hereof and the Company agrees to deliver such Officers’
Certificate to the Trustee and the Conversion Agent promptly after the occurrence of any such adjustment. Neither the Trustee nor the Conversion Agent shall be accountable with respect to, and makes not representation as to, the validity or value of
any securities or assets issued upon conversion of Notes, and neither the Trustee nor the Conversion Agent shall be responsible for the failure by the Company to comply with any provisions of this Article 11. 

Neither the Trustee nor the Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any
supplemental indenture executed pursuant to Section 11.11, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is
obligated to file with the Trustee and the Conversion Agent pursuant to Section 11.11 hereof. 
 The Trustee and the Conversion Agent
shall not at any time be under any duty or responsibility to any Holder of Notes to either calculate the Conversion Price or determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the method employed herein, or in any supplemental indenture provided to be employed, in making the same and shall be protected in relying upon an Officers’ Certificate
with respect to the same. Neither the Trustee nor the Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common

  
 73 

 
Stock or stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion; and the Trustee and the Conversion Agent shall not be
responsible or liable for any failure of the Company to comply with any of the covenants of the Company contained in this Article. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by
Section 11.01 has occurred which makes the Securities eligible for conversion until the Company has delivered to the Trustee and the Conversion Agent an Officers’ Certificate stating that such event has occurred, on which certificate the
Trustee and any the Conversion Agent may conclusively rely, and the Company agrees to deliver such Officers’ Certificate to the Trustee and the Conversion Agent promptly after the occurrence of any such event.

 [FORM OF REVERSE SIDE OF NOTE] 

5.000% Convertible Senior Note due 2019 

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated. 
 1. Interest. Whiting Petroleum Corporation, a Delaware corporation (the “Company”), promises to pay
interest on the principal amount of this Note at 5.000% per annum until maturity. The Company will pay interest semi-annually in arrears on March 15 and September 15 of each year, commencing September 15, 2016, or if any such day
is not a Business Day, on the next succeeding Business Day (each an “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, March 15,
2016; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest
shall accrue from such next succeeding Interest Payment Date. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a
rate that is the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 2.
Method of Payment. The Company will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the March 1 or September 1 next preceding the Interest Payment Date, even if such Notes are
cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 307 of the Original Indenture with respect to Defaulted Interest. Holders must surrender Notes to the Paying Agent to collect payments
of principal and premium, if any, together with accrued and unpaid interest 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 within the City
and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the Security Register of Holders, and provided that payment by wire transfer of
immediately available funds will be required with respect to any amounts due on all Global Securities and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be
in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

3. Paying Agent, Security Registrar and Conversion Agent. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under
the Indenture, will act as Paying Agent, Security Registrar and Conversion Agent. The Company may change any Paying Agent, Security Registrar or Conversion Agent without notice to any Holder. The Company or any of its Domestic Subsidiaries may act
in any such capacity. 
 4. Indenture. This Note is one of a duly authorized issue of the series of Securities of the Company
designated as its 5.000% Convertible Senior Notes due 2019 (the “Notes”), issued under a Senior Indenture, dated as of March 23, 2016 (“Original Indenture”), among the Company, the Guarantors and the Trustee,
as supplemented and amended by the First  

  
 A - 3 

 
Supplemental Indenture (herein so called), dated as of March 23, 2016 (the Original Indenture, as so supplemented and amended, being called herein the “Indenture”).
Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA (15 U.S. Code §§
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. The Notes are unsecured senior obligations of the Company limited to $96,812,000 aggregate principal amount
in the case of Notes issued on the Issue Date. The Company may, subject to Sections 2.05 and 4.09 of the First Supplemental Indenture, issue Additional Notes under the Indenture after the Issue Date in either a limited or an unlimited aggregate
principal amount. Any Additional Notes so issued and the Initial Notes shall be treated as a single class under the Indenture. 
 5.
Optional Redemption. 
 (a) Except as set forth in subparagraph (b) of this Paragraph 5 or in Section 4.15 of the First
Supplemental Indenture, the Company shall not have the option to redeem the Notes prior to December 15, 2018. On and after December 15, 2018, the Company may on any one or more occasions redeem the Notes, in whole or in part, at a
Redemption Price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment
Date that is on or prior to the Redemption Date). 
 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any
time prior to December 15, 2018, the Company may on any one or more occasions redeem the Notes, in whole or in part, at the Redemption Price of 100% of the principal amount thereof plus the Applicable Premium as of, plus accrued and unpaid
interest, if any, to, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date). 

6. Mandatory Redemption. 

Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect
to the Notes or to repurchase the Notes at the option of the Holders. 
 7. Repurchase at Option of Holder. 

(a) Within 30 days following the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control
Offer”) to repurchase all or any part (equal to $2,000 or any integral $1,000 multiple in excess thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and
unpaid interest, if any, to the date of settlement (the “Change of Control Settlement Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or
prior to the Change of Control Settlement Date. Within 30 days following a Change of Control, the Company shall mail a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction that constitutes the Change of
Control and setting forth the procedures governing the Change of Control Offer as required by Section 4.15 of the First Supplemental Indenture. 

(b) On the 361st day after an Asset Sale, if the aggregate amount of Excess Proceeds then exceeds $50.0 million, the Company shall commence an
offer to all Holders of Notes (an 

  
 A - 4 

 
“Asset Sale Offer”) pursuant to Section 3.04 of the First Supplemental Indenture, and to all holders of any Pari Passu Indebtedness then outstanding, to purchase the
maximum principal amount of Notes and such Pari Passu Indebtedness that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes plus accrued and unpaid interest, if any,
thereon to the Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, in accordance with the procedures set forth in the
Indenture. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes surrendered
by Holders thereof and Pari Passu Indebtedness surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or integral $1,000 multiples in excess thereof, shall be purchased) on the basis of the aggregate principal amount of tendered Notes and Pari
Passu Indebtedness. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled
“Option of Holder to Elect Purchase” on the reverse of the Notes. 
 8. Notice of Redemption. Notice of redemption
will be mailed at least 30 days but not more than 60 days (except as otherwise provided in the Indenture if the notice is issued in connection with a Discharge) before the Redemption Date to each Holder whose Notes are to be redeemed at its
registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on
Notes or portions thereof called for redemption. 
 9. Denominations, Transfer, Exchange. The Notes are in registered form without
coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Company or the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents, and may require a Holder to pay any taxes due on transfer or exchange. 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, it need not exchange or register the transfer of any Notes for a period of 15 days before the day of the mailing of a notice of redemption of Notes selected for
redemption. 
 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, the Notes or the Subsidiary Guarantees may be
amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes, and any existing default or compliance with any provision of the Indenture, the Notes or the Subsidiary
Guarantees may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture, the Notes or the Subsidiary Guarantees may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes 

  
 A - 5 

 
in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes pursuant to Article 5 of the
First Supplemental Indenture, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, including any increase in
the Conversion Rate or other consideration due upon conversion of the Notes (whether or not subject to time limitations or other conditions), as determined in accordance with Section 901 of the Original Indenture (as amended by
Section 9.01 of the First Supplemental Indenture), to secure the Notes or the Subsidiary Guarantees pursuant to Section 4.12 of the First Supplemental Indenture or otherwise, to provide for the issuance of Additional Notes in accordance
with the limitations set forth in the Indenture, to add any additional Guarantor with respect to the Notes or to evidence the release of any Guarantor from its Subsidiary Guarantee, in each case as provided in the Indenture, to comply with the
requirements of Section 11.11 of the First Supplemental Indenture, to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee, to add to, change or eliminate any provisions of the Indenture in respect of
one or more other series of Securities, to establish the forms or terms of Securities of any other series as permitted by the Indenture or to make provision with respect to adjustments to the Conversion Rate as required by the First Supplemental
Indenture or to increase the Conversion Rate in accordance with the First Supplemental Indenture. 
 12. Defaults and Remedies.
Events of Default with respect to the Notes include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in payment when due of the principal of or premium, if any, on the Notes when due at Stated
Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; (iii) failure by the Company to comply with Section 4.07, 4.09, 4.10, 4.15 or 5.01 of the First Supplemental Indenture; (iv) failure by the
Company or a Guarantor for 60 days (or 180 days in the case of Reporting Failure) after notice of such failure to the Company by the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding to comply with any of its
other agreements in the Indenture or the Notes; (v) 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), whether such Indebtedness or guarantee now exists or is created after the Issue Date, if such default (a) is caused by a
failure to pay principal of, or premium or interest, if any, on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness (a “Payment Default”) or (b) results in the acceleration of such Indebtedness
prior to its Stated Maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $50.0 million or more; provided, that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the
applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default under the Indenture and any consequential acceleration of the Notes shall be automatically rescinded; (vi) failure by the Company or any
of its Significant Subsidiaries to pay final judgments aggregating in excess of $50.0 million, which judgments are not paid, discharged or stayed (including a stay pending appeal) for a period of 60 days after the date of such final judgment (or, if
later, the date when payment is due pursuant to such judgment); (vii) except as permitted by the Indenture, any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force
and effect or any Guarantor, or any Person acting on behalf of 

  
 A - 6 

 
any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee (other than by reason of release of a Guarantor from its Subsidiary Guarantee in accordance with the terms of
the Indenture); (viii) certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary as specified
in Section 501(8) or 501(9) of the Original Indenture (as amended by Section 6.01 of the First Supplemental Indenture) and (ix) failure by the Company to satisfy its conversion or payment obligations in accordance with Article 11 of
the First Supplemental Indenture (x) upon a Holder’s exercise of its Early Conversion rights or (y) upon the Company’s exercise of its Mandatory Conversion rights, which failure in each case is not cured within five Business
Days. If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the
Notes to be due and payable immediately. Notwithstanding the preceding, in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group
of Subsidiaries that, taken together, would constitute a Significant Subsidiary described in Section 501(8) or 501(9) of the Original Indenture (as amended by Section 6.01 of the First Supplemental Indenture), all outstanding Notes will
become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes
may direct the Trustee in its exercise of any trust or power conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default with respect to the Notes (except a Default or Event of Default
relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in principal amount of the Notes then outstanding by notice to the Trustee may on behalf of
the Holders of all of the Notes waive any past Default or Event of Default with respect to the Notes and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of or premium, if any, or
interest on the Notes, or conversion of the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, the Company is required upon becoming aware
of any Default or Event of Default with respect to the Notes, to deliver to the Trustee a statement specifying such Default or Event of Default. 

13. Discharge. The Notes are subject to discharge upon the terms and conditions specified in the Indenture. 

14. Conversion. The Notes shall be convertible into shares of Common Stock in accordance with Article 11 of the First Supplemental
Indenture. To convert a Note at its option, a Holder must satisfy the requirements of Section 11.02(a) of the First Supplemental Indenture. A Holder may convert a portion of a Note in an Early Conversion if the portion is $2,000 principal
amount or an integral multiple of $1,000 principal amount. The Notes are convertible at the Company’s option into shares of Common Stock in accordance with Section 11.01(b) of the First Supplemental Indenture. Upon conversion of a Note,
the Holder thereof shall be entitled to receive the shares of Common Stock payable upon conversion in accordance with Article 11 of the First Supplemental Indenture, at the Conversion Rate specified in the First Supplemental Indenture, as adjusted
from time to time as provided in the First Supplemental Indenture. 
 15. No Recourse Against Others. No past, present or future
director, officer, employee, incorporator, member, partner or stockholder or other owner of Capital Stock of the 

  
 A - 7 

 
Company or any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 

16. Authentication. This Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee
or an authenticating agent. 
 17. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such

18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company
has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers and corresponding ISIN 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. 

19. Governing Law. THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK. 
 20. Successor Entity. In the event a successor assumes all the obligations of the Company under the Notes and the Indenture,
