discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged (in each case other than Indebtedness Incurred under any revolving credit facility unless such

Restricted Subsidiary to the extent the Issuer and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

be determined in good faith by a responsible financial or accounting Officer of the Issuer (and shall include any applicable Pro Forma Cost Savings). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the
interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness). 

If any Indebtedness is incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness

THE NOTES 

SECTION 2.01 Amount of Notes. 
 Upon written order of the Issuer, the Trustee shall authenticate Notes for original issue on the Issue Date in the aggregate principal amount not to exceed $250,000,000 and, subject to
Section 4.06, unless suspended pursuant to Section 4.21, the Trustee shall authenticate Additional Notes in an unlimited principal amount, upon a written order of the Issuer in the form of an Officers’ Certificate, which
shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated, and the names and delivery instructions for each Holder. 
 Upon receipt of a written order of the Issuer in the form of an Officers’ Certificate, the Trustee shall authenticate Notes in substitution for Notes originally issued to reflect any name change of
the Issuer. Any Additional Notes and the Exchange Notes shall be part of the same issue as the Notes being issued on the date hereof and will vote on all matters as one class with the Notes being issued on the date hereof, including, without
limitation, waivers, amendments, redemptions and offers to purchase. For the purposes of this Indenture, except for Section 4.06, references to the Notes include Additional Notes and Exchange Notes, if any. 

SECTION 2.02 Form and Dating; Book Entry Provisions. 
 (a) The Notes and the Trustee’s certificate of authentication with respect thereto shall be substantially in the form set forth in Exhibit A, which is incorporated in and forms a part of
this Indenture. The Notes may have notations, legends or endorsements required by law, rule or usage to which the Issuer is subject. Each Note shall be dated the date of its authentication. 

(b) (i) The Notes will be offered and sold by the Issuer pursuant to a Purchase Agreement. The Notes will be resold initially only to
(i) QIBs in reliance on Rule 144A under the Securities Act and (ii) Persons other than U.S. Persons (as defined in Regulation S) in reliance on Regulation S under the Securities Act. Notes may thereafter be transferred to, among others,
QIBs, IAIs and purchasers in reliance on Regulation S, subject to the restrictions on transfer set forth herein. Notes initially resold pursuant to Rule 144A shall be issued in the form of one or more permanent global Notes in definitive, fully
registered form without interest coupons (collectively, the “Rule 144A Global Note”); and Notes initially resold to IAIs (the “IAI Notes”) shall be issued in the form of one or more permanent global Notes in
definitive, fully registered form without interest coupons (collectively, the “IAI Global Note”); and Notes initially resold pursuant to Regulation S shall be issued initially in the form of one or

  
 -28-

 
more global securities in fully registered form (collectively, the “Regulation S Global Note”), in each case without interest coupons and with the global securities legend and
the applicable restricted securities legend set forth in Exhibit C hereto, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Notes Custodian and registered in the name of the Depository or a
nominee of the Depository, duly executed by the Issuer and authenticated by the Trustee as provided in this Indenture. Except as set forth in this Section 2.02(b), beneficial ownership interests in the Regulation S Global Note will not
be exchangeable for interests in the Rule 144A Global Note, the IAI Global Note or any other Note prior to the expiration of the Distribution Compliance Period. 
 (A) Beneficial interests in Regulation S Global Notes or IAI Global Notes may be exchanged for interests in Rule 144A Global Notes if (1) such exchange occurs in connection with a transfer of Notes
in compliance with Rule 144A and (2) the transferor of the beneficial interest in the Regulation S Global Note or the IAI Global Note, as applicable, first delivers to the Trustee a written certificate (in a form satisfactory to the Trustee) to
the effect that the beneficial interest in the Regulation S Global Note or the IAI Global Note, as applicable, is being transferred to a Person (A) who the transferor reasonably believes to be a QIB, (B) purchasing for its own account or
the account of a QIB in a transaction meeting the requirements of Rule 144A, and (C) in accordance with all applicable securities laws of the States of the United States and other jurisdictions. 

(B) Beneficial interests in Regulation S Global Notes and Rule 144A Global Notes may be exchanged for an interest in IAI
Global Notes if (1) such exchange occurs in connection with a transfer of the securities in compliance with an exemption under the Securities Act and (2) the transferor of the Regulation S Global Note or Rule 144A Global Note, as
applicable, first delivers to the Trustee a written certificate (in a form reasonably satisfactory to the Trustee) to the effect that (A) the Regulation S Global Note or Rule 144A Global Note, as applicable, is being transferred to an
“accredited investor” within the meaning of 501(a)(1), (2), (3) or (7) under the Securities Act that is an institutional investor acquiring the securities for its own account or for the account of such an institutional accredited
investor, in each case in a minimum principal amount of Notes of US$250,000, for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act and (B) in accordance with
all applicable securities laws of the States of the United States and other jurisdictions. 
 (C) Beneficial
interests in a Rule 144A Global Note or an IAI Global Note may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Note, whether before or after the expiration of the Distribution Compliance Period, only
if the transferor first delivers to the Trustee a written certificate (in the form reasonably satisfactory to the Trustee) to the effect that such transfer is being made in accordance with Regulation S or Rule 144 (if applicable). 

(D) Exchange Notes exchanged for interests in the Rule 144A Notes, the Regulation S Notes, and the IAI Notes will be
issued in the form of a permanent global Note, substantially in the form of Exhibit B, which is hereby incorporated by reference and made a part of this Indenture, deposited with the Registrar as hereinafter provided, including the
appropriate legend set forth in Section 2.16(e) (the “Exchange Global Note”). The Exchange Global Note will be deposited upon issuance with, or on behalf of, the Registrar as custodian for DTC, duly executed by the
Issuer and authenticated by the Trustee as hereinafter provided. The Exchange Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single
certificate. 
 (E) The Rule 144A Global Note, the IAI Global Note, the Regulation S Global Note and the Exchange
Global Note are collectively referred to herein as “Global Notes.” The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the
Depository or its nominee as hereinafter provided. 

  
 -29-

 (c) Book-Entry Provisions. This Section 2.02(c) shall apply only to a
Global Note deposited with or on behalf of the Depository. 
 (A) The Issuer shall execute and the Trustee shall,
in accordance with this Section 2.02(c), authenticate and deliver initially one or more Global Notes that (A) shall be registered in the name of the Depository for such Global Note or Global Notes or the nominee of such Depository
and (B) shall be delivered by the Trustee to such Depository or pursuant to such Depository’s instructions or held by the Trustee as custodian for the Depository. 

(B) Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this
Indenture with respect to any Global Note held on their behalf by the Depository or by the Trustee as the custodian of the Depository or under such Global Note, and the Issuer, the Trustee and any agent of the Issuer or the Trustee shall be entitled
to treat the Depository as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a
beneficial interest in any Global Note. 
 (d) Definitive Notes. Except as provided in this Section 2.02 or
Sections 2.16 or 2.17, owners of beneficial interests in Notes shall not be entitled to receive physical delivery of Definitive Notes. 
 (e) The terms and provisions contained in the Notes shall constitute, and are expressly made, a part of this Indenture and, to the extent applicable, the Issuer, the Subsidiary Guarantors and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms and provisions and agree to be bound thereby. 

(f) The Notes may be presented for registration of transfer and exchange at the offices of the Registrar. 

SECTION 2.03 Execution and Authentication. 
 An Officer of the Issuer (who shall, in each case, have been duly authorized by all requisite corporate actions) shall sign the Notes for the Issuer by manual or facsimile signature. 

If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office at the time the
Trustee authenticates the Note, the Note shall be valid nevertheless. 
 No Note shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized officer, and such
certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly 

  
 -30-

 
authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Issuer, and the Issuer
shall deliver such Note to the Trustee for cancellation as provided in Section 2.12, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture. 
 The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to
authenticate the Notes. Unless otherwise provided in the appointment, an authenticating agent may authenticate the Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by
such agent. An authenticating agent has the same rights as an Agent to deal with the Issuer and Affiliates of the Issuer. Each Paying Agent is designated as an authenticating agent for purposes of this Indenture. 

The Notes shall be issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000.

 SECTION 2.04 Registrar and Paying Agent. 
 The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”), and an office or agency where Notes may be
presented for payment (the “Paying Agent”) and an office or agency where notices and demands to or upon the Issuer, if any, in respect of the Notes and this Indenture may be served. The Registrar shall keep a register of the Notes
and of their transfer and exchange. If and for so long as the Trustee is not the Registrar, the Trustee shall have the right to inspect the register of the Notes during regular business hours. The Issuer may have one or more additional Paying
Agents. The term “Paying Agent” includes any additional Paying Agent. The Issuer or any Affiliate thereof may act as Paying Agent. 
 The Issuer shall enter into an appropriate agency agreement, which shall incorporate the provisions of the TIA, with any Agent that is not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee of the name and address of any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee
shall act as such and shall be entitled to appropriate compensation in accordance with Section 7.07. Either of the Issuer or any Wholly Owned Subsidiary may act as Paying Agent, Registrar, co-registrar or transfer agent. 

The Issuer initially appoints the Trustee as Registrar, Paying Agent and Agent for service of notices and demands in connection with the
Notes and this Indenture. 
 SECTION 2.05 Paying Agent To Hold Money in Trust. 

On or prior to each due date of the principal or interest on any Notes, the Issuer shall deposit with the Paying Agent a sum sufficient
to pay such principal and interest when so becoming due. Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium or interest on the Notes
(whether such money has been paid to it by the Issuer or any other obligor on the Notes or the Subsidiary Guarantors), and the Issuer and the Paying Agent shall notify the Trustee in writing of any default by the Issuer (or any other obligor on the
Notes) in making any such payment. If either of the Issuer or a Subsidiary of a Issuer serves as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. Money held in trust by the Paying Agent need
not be segregated except as required by law and in no event shall the Paying Agent be liable for any interest on any money received by it hereunder. The Issuer at any time may require the Paying Agent to pay all money held by it to the Trustee and
account for 

  
 -31-

 
any funds disbursed and the Trustee may at any time during the continuance of any Event of Default specified in Section 6.01(a) or (b), upon written request to the Paying
Agent, require such Paying Agent to pay forthwith all money so held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon making such payment, the Paying Agent shall have no further liability for the money delivered
to the Trustee. 
 SECTION 2.06 Holder Lists. 
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders and shall otherwise comply with TIA
Section 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least five Business Days before each Interest Payment Date, and at such other times as the Trustee may reasonably request in writing, a list in such
form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders and the Issuer, and shall otherwise comply with TIA Section 312(a). 

SECTION 2.07 Transfer and Exchange. 
 Subject to Sections 2.02(b), 2.16 and 2.17, when Notes are presented to the Registrar with a request from the Holder thereof to register a transfer or to exchange them for an
equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer as requested if the requirements of this Indenture are met. Every Note presented or surrendered for registration of transfer or exchange
shall be duly endorsed or be accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his attorneys duly authorized in writing. To permit registrations of transfers
and exchanges, the Issuer shall issue and execute and the Trustee shall authenticate new Notes (and the Subsidiary Guarantors shall execute the guarantee thereon) evidencing such transfer or exchange at the Registrar’s request. No service
charge shall be made to the Holder for any registration of transfer or exchange. The Issuer may require from the Holder payment of a sum sufficient to cover any transfer taxes or other governmental charge that may be imposed in relation to a
transfer or exchange, but this provision shall not apply to any exchange pursuant to Section 2.11, 3.06, 4.08, 4.20 or 8.05 (in which events the Issuer shall be responsible for the payment of such taxes). The
Registrar shall not be required to exchange or register a transfer of any Note for a period of 15 days immediately preceding the mailing of notice of redemption of Notes to be redeemed or of any Note selected, called or being called for redemption
except the unredeemed portion of any Note being redeemed in part. 
 Any Holder of any Global Note shall, by acceptance of such
Global Note, agree that transfers of the beneficial interests in such Global Note may be effected only through a book entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in such
Global Note shall be required to be reflected in a book entry. 
 Each Holder of a Note agrees to indemnify the Issuer and the
Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable U.S. Federal or state securities law. 

Except as expressly provided herein, neither the Trustee nor the Registrar shall have any duty to monitor the Issuer’s compliance
with or have any responsibility with respect to the Issuer’s compliance with any Federal or state securities laws. 

  
 -32-

 SECTION 2.08 Replacement Notes. 

If a mutilated Note is surrendered to the Registrar or the Trustee, or if the Holder claims that the Note has been lost, destroyed or
wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note (and the Subsidiary Guarantors shall execute the guarantee thereon) if such Holder furnishes to the Issuer and the Trustee evidence reasonably acceptable
to them of the ownership and the destruction, loss or theft of such Note and if the requirements of Section 8-405 of the New York Uniform Commercial Code as in effect on the date of this Indenture are met. If required by the Trustee or the
Issuer, an indemnity bond shall be posted by such Holder, sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Subsidiary Guarantors, the Trustee or any Paying Agent from any loss that any of them may suffer if such
Note is replaced. The Issuer and the Trustee may charge such Holder for their reasonable out-of-pocket expenses in replacing such Note (including, without limitation, attorneys’ fees and disbursements) in replacing such Note. Every replacement
Note shall constitute a contractual obligation of the Issuer. 
 SECTION 2.09 Outstanding Notes. 

The Notes outstanding (the “Outstanding Notes”) at any time are all Notes that have been authenticated by the Trustee
except for (a) those cancelled by it, (b) those delivered to it for cancellation, (c) to the extent set forth in Sections 9.01 and 9.02, on or after the date on which the conditions set forth in
Section 9.01 or 9.02 have been satisfied, those Notes theretofore authenticated and delivered by the Trustee hereunder and (d) those described in this Section 2.09 as not outstanding. Subject to
Section 2.10, a Note does not cease to be outstanding because either of the Issuer or one of its Affiliates holds the Note. 
 If a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to it that the replaced Note is held by a bona
fide purchaser in whose hands such Note is a legal, valid and binding obligation of the Issuer. 
 If the Paying Agent holds
in trust, in its capacity as such, on any Redemption Date or maturity date, money sufficient to pay all accrued interest and principal with respect to the Notes payable on that date and is not prohibited from paying such money to the Holders thereof
pursuant to the terms of this Indenture, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. 
 SECTION 2.10 Treasury Notes. 
 In determining whether the Holders of the
required principal amount of Notes have concurred in any declaration of acceleration or notice of default or direction, waiver or consent or any amendment, modification or other change to this Indenture, Notes owned by either of the Issuer or any
Affiliate of either of the Issuer shall be disregarded as though they were not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment,
modification or other change to this Indenture, only Notes as to which a Responsible Officer of the Trustee has received an Officers’ Certificate stating that such Notes are so owned shall be so disregarded. Notes so owned which have been
pledged in good faith shall not be disregarded if the pledgee established to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the pledgee is not a Issuer, a Subsidiary Guarantor, any other obligor
on the Notes or any of their respective Affiliates. 

  
 -33-

 SECTION 2.11 Temporary Notes. 

Until definitive Notes are prepared and ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes.
Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer consider appropriate for temporary Notes and as shall be acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare
and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes. 

SECTION 2.12 Cancellation. 
 The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer,
exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall (subject to the record-retention requirements of the Exchange Act) destroy
cancelled Notes. The Trustee shall deliver a certificate of such destruction to the Issuer. The Issuer may not reissue or resell, or issue new Notes to replace, Notes that the Issuer has redeemed or paid, or that have been delivered to the Trustee
for cancellation, other than in accordance with the express provisions of this Indenture. 
 SECTION 2.13 Defaulted
Interest. 
 If the Issuer defaults on a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the
extent permitted by law) any interest payable on the defaulted interest, in accordance with the terms hereof, to the Persons who are Holders of such Notes on a subsequent special record date, which date shall be at least five Business Days prior to
the payment date. The Issuer shall fix such special record date and payment date in a manner satisfactory to the Trustee. The Issuer shall promptly mail to each Holder of such Notes a notice that states the special record date, the payment date and
the amount of defaulted interest, and interest payable on defaulted interest, if any, to be paid. The Issuer may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements (if applicable) of any
securities exchange on which the Notes may be listed and, upon such notice as may be required by such exchange, if, after written notice given by the Issuer to the Trustee of the proposed payment pursuant to this sentence, such manner of payment
shall be deemed practicable by the Trustee. 
 SECTION 2.14 CUSIP Number. 

The Issuer in issuing the Notes may use a “CUSIP” number, ISIN and “Common Code” number (in each case if then
generally in use), and if so, such CUSIP number, ISIN and Common Code number shall be included in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the
correctness or accuracy of such number either as printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify, and in any event within 10
Business Days, the Trustee of any such CUSIP number, ISIN and Common Code number used by the Issuer in connection with the issuance of the Notes and of any change in the CUSIP number, ISIN and Common Code number. 

SECTION 2.15 Deposit of Moneys. 
 Subject to the following paragraph, prior to 12:00 p.m., New York City time, on each Interest Payment Date and maturity date, the Issuer shall have deposited with the Paying Agent in immediately available
funds money sufficient to make cash payments, if any, due on such Interest Payment 

  
 -34-

 
Date or maturity date, as the case may be. The principal and interest on Global Notes shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the
sole holder of the Global Notes represented thereby. The principal and interest on Physical Notes shall be payable, either in person or by mail, at the office of the Paying Agent. 

If a Holder has given wire transfer instructions to Issuer at least ten Business Days prior to the applicable Interest Payment Date, the
Issuer (through the Paying Agent) will make all payments on such Holder’s Notes by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or
agency of the Payment Agent for the Notes unless the Issuer (with notice to the Paying Agent) elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders. 

SECTION 2.16 Special Transfer Provisions. 
 (a) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Registrar with a request: 

(x) to register the transfer of such Definitive Notes; or 

(y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations,

 the Registrar shall register the transfer or make the exchange as requested if the requirements for such transaction are met;
provided, however, that the Definitive Notes surrendered for transfer or exchange: 
 (i) shall be
duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 

(ii) if such Definitive Notes are required to bear a restricted securities legend, they are being transferred or exchanged
pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.16(b) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as
applicable: 
 (A) if such Definitive Notes are being delivered to the Registrar by a Holder for registration in
the name of such Holder, without transfer, a certification from such Holder to that effect; or 
 (B) if such
Definitive Notes are being transferred to the Issuer, a certification to that effect; or 
 (C) if such
Definitive Notes are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the
Securities Act: (i) a certification to that effect (in the form set forth on the reverse of the Note) and (ii) if the Issuer or the Registrar so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the
compliance with the restrictions set forth in the legend set forth in Section 2.16(e)(i). 
 (b) Restrictions on
Transfer of a Definitive Note for a Beneficial Interest in a Global Note. A Definitive Note may not be exchanged for a beneficial interest in a Rule 144A Global Note, an 

  
 -35-

 
IAI Global Note or a Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Note, duly endorsed or accompanied by
appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 
 (i) certification, in
the form set forth on the reverse of the Note, that such Definitive Note is either (A) being transferred to a QIB in accordance with Rule 144A, (B) being transferred to an IAI or (C) being transferred outside the United States in an
offshore transaction within the meaning of Regulation S and in compliance with Rule 904 under the Securities Act; and 
 (ii) written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Note (in the case of a
transfer pursuant to clause (b)(i)(A)), IAI Global Note (in the case of a transfer pursuant to clause (b)(i)(B)) or Regulation S Global Note (in the case of a transfer pursuant to clause (b)(i)(C)) to reflect an increase in the aggregate principal
amount of the Notes represented by the Rule 144A Global Note, IAI Global Note or Regulation S Global Note, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase, 

then the Trustee shall cancel such Definitive Note and cause, or direct the Notes Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depository and the Notes Custodian, the aggregate principal amount of Notes represented by the Rule 144A Global Note, IAI Global Note or Regulation S Global Note, as applicable, to be increased by the aggregate
principal amount of the Definitive Note to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Note, IAI Global Note or Regulation S Global
Note, as applicable, equal to the principal amount of the Definitive Note so canceled. If no Rule 144A Global Notes, IAI Global Notes or Permanent Regulation S Global Notes, as applicable, are then outstanding, the Issuer shall issue and the Trustee
shall authenticate, upon written order of the Issuer in the form of an Officers’ Certificate, a new Rule 144A Global Note, IAI Global Note or Regulation S Global Note, as applicable, in the appropriate principal amount. 

(c) Transfer and Exchange of Global Notes. 
 (A) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this Indenture (including applicable restrictions on transfer set
forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note shall deliver to the Registrar a written order given in accordance with the Depository’s procedures containing
information regarding the participant account of the Depository to be credited with a beneficial interest in such Global Note. The Registrar shall, in accordance with such instructions, instruct the Depository to credit to the account of the Person
specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred. 

(B) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note,

the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred. 

(C) Notwithstanding any other provisions of Article II (other than the provisions set forth in Section 2.17), a Global Note
may not be transferred as a whole except by the Depository to a nominee

Section 2.17, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.16 (including the certification requirements set forth on the reverse of
the Notes intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer or the

interests in a Global Note have either been exchanged for Definitive Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Depository for cancellation or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes, redeemed, purchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books

Section 2.02 shall be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such
transfer complies with Section 2.16 hereof and (i) the Depository notifies the Issuer that it is unwilling or unable to continue as Depository for such Global Note and the Depository fails to appoint a successor depository or if at

notifies the Trustee in writing that it elects to cause the issuance of Notes in definitive form, then, upon surrender by the relevant Global Note Holder of its Global Note, Notes in such form will be issued to each Person that such Global Note
Holder and the Depository identify as being the beneficial owner of the related Notes, or (iii) an Event of Default has occurred and is continuing.

(d) In the event of the occurrence of one of the events specified in Section 2.17(a) hereof, the Issuer shall promptly make
available to the Trustee a reasonable supply of Definitive Notes in definitive, fully registered form without interest coupons. In the event that the Definitive Notes are not issued to each such beneficial owner promptly after the Registrar has
received a request from the Holder of a Global Note to issue such certificated Note, the Issuer expressly acknowledge, with respect to the right of any Holder to pursue a remedy pursuant to Article 6 of this Indenture, the right of any
beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial holder’s Notes as if such certificated Notes had been issued. 

(e) By its acceptance of any Note bearing any Legend in Section 2.16(e), each Holder of such Note acknowledges the
restrictions on transfer of such Note set forth in this Indenture and in such Legend in Section 2.16(e) and agrees that it shall transfer such Note only as provided in this Indenture.

Registrar.

 REDEMPTION 
 SECTION 3.01 Election To Redeem; Notices to Trustee.

 If the Issuer elects to redeem Notes pursuant to paragraph 6 of such Notes, at least 40 days prior to the Redemption Date
(unless a shorter notice shall be agreed to in writing by the Trustee), the Issuer shall notify the Trustee in writing of the Redemption Date, the principal amount of Notes to be 

  
 -40-

 
redeemed and the redemption price, and deliver to the Trustee an Officer’s Certificate stating that such redemption will comply with the conditions contained in paragraph 6 of the Notes.
Notice given to the Trustee pursuant to this Section 3.01 may not be revoked after the time that notice is given to Holders pursuant to Section 3.03. 
 SECTION 3.02 Selection by Trustee of Notes To Be Redeemed. 
 In the event
that less than all of the Notes are to be redeemed pursuant to a redemption made pursuant to paragraph 6 of such Notes, selection of the Notes for redemption shall be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which such Notes are listed or, if such Notes are not then listed on a national securities exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem appropriate;
provided, however, that no Notes of a principal amount of $2,000 or less shall be redeemed in part. If a partial redemption is made pursuant clause (c) of paragraph 6 of the Notes, selection of the Notes or portions thereof for
redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depository), unless that method is otherwise prohibited. The Trustee shall promptly
notify the Issuer of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. The Trustee may select for redemption portions of the principal of the Notes that have
denominations larger than $2,000. For all purposes of this Indenture unless the context otherwise requires, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Issuer may
acquire Notes by means other than redemption, whether pursuant to an Issuer tender offer, open market purchase or otherwise, provided such acquisition does not otherwise violate the other terms of this Indenture. 

SECTION 3.03 Notice of Redemption. 
 At least 30 days, and no more than 60 days, before a Redemption Date, the Issuer shall mail, or cause to be mailed, a notice of redemption by first-class mail to each Holder to be redeemed at his or her
last address as the same appears on the registry books maintained by the Registrar pursuant to Section 2.04, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection
with a satisfaction and discharge of this Indenture. If the Issuer mails such notice to Holders, it shall mail a copy of such notice to the Trustee at the same time. 
 The notice shall identify the Notes to be redeemed (including the CUSIP numbers, ISIN and Common Code numbers, if any thereof) and shall state: 

(i) the Redemption Date; 
 (ii) the redemption price and the amount of premium (or the manner of calculation the redemption price and/or premium) and accrued interest to be paid; 

(iii) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that,
after the Redemption Date and upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued; 
 (iv) the name and address of the Paying Agent; 
 (v) that Notes
called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

  
 -41-

 (vi) that unless the Issuer defaults in making the redemption payment,
interest on Notes called for redemption ceases to accrue on and after the Redemption Date; 
 (vii) the provision
of paragraph 6 of the Notes pursuant to which the Notes called for redemption are being redeemed; and 
 (viii)
the aggregate principal amount of Notes that are being redeemed. 
 At the Issuer’s written request made at least ten
Business Days prior to the date on which notice is to be given, the Trustee shall give the notice of redemption prepared by the Issuer, in the Issuer’s name and at the Issuer’s sole expense. In such event, the Issuer shall provide the
Trustee with the information required by this Section 3.03. 
 SECTION 3.04 Effect of Notice of Redemption.

 Once the notice of redemption described in Section 3.03 is mailed, Notes called for redemption become due and
payable on the Redemption Date and at the redemption price, including any premium, plus interest accrued to the Redemption Date. Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price, including any premium, plus
interest accrued to the Redemption Date, provided that if the Redemption Date is after a regular record date and on or prior to the Interest Payment Date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on
the relevant record date, and provided, further, that if a Redemption Date is not a Business Day, payment shall be made on the next succeeding Business Day and no interest shall accrue for the period from such Redemption Date to such
succeeding Business Day. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 
 SECTION 3.05 Deposit of Redemption Price. 
 On or prior to 12:00 p.m.,
New York City time, on each Redemption Date, the Issuer shall deposit with the Paying Agent in immediately available funds money sufficient to pay the redemption price of, including premium, if any, and accrued interest on all Notes to be redeemed
on that date other than Notes or portions thereof called for redemption on that date which have been delivered by the Issuer to the Trustee for cancellation. Promptly after the calculation of the redemption price, the Issuer will give the Trustee
and any Paying Agent written notice thereof. 
 On and after any Redemption Date, if money sufficient to pay the redemption
price of, including premium, if any, and accrued interest on Notes called for redemption shall have been made available in accordance with the preceding paragraph, the Notes called for redemption will cease to accrue interest and the only right of
the Holders of such Notes will be to receive payment of the redemption price of and, subject to the first proviso in Section 3.04, accrued and unpaid interest on such Notes to the Redemption Date. If any Note surrendered for redemption
shall not be so paid, interest will be paid, from the Redemption Date until such redemption payment is made, on the unpaid principal of the Note and any interest not paid on such unpaid principal, in each case, at the rate and in the manner provided
in the Notes. 
 SECTION 3.06 Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Issuer shall execute and the Trustee shall authenticate for the Holder thereof a
new Note equal in principal amount to the unredeemed portion of the Note surrendered.

reason, the Issuer shall nevertheless continue filing the reports specified in the preceding sentence with the SEC within the time periods required unless the SEC will not accept such a filing. Delivery of such reports, information and documents to
the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely on Officer’s Certificates). The Issuer agrees that it shall not take any action for the purpose of causing the SEC not to accept such filings. If,
notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Issuer shall post the reports specified in the preceding sentence on its website within the time periods that would apply if the Issuer were required to file
such reports with the SEC. At any time that any of the Issuer’s Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual financial information required by this paragraph shall include a reasonably detailed presentation, either

insist upon, or plead (as a defense or otherwise) or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other 

  
 -43-

 
law which would prohibit or forgive any of the Issuer and the Subsidiary Guarantors from paying all or any portion of the principal of, premium, if any, and/or interest on the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that they may lawfully do so) each of the Issuer and the Subsidiary Guarantors
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.

(a) The Issuer and Subsidiary Guarantors will deliver to the Trustee within 120 days after the end of each fiscal year of the Issuer an

prior to such acquisition;

the types of Indebtedness described above, the Issuer, in its sole discretion, may classify such item of Indebtedness (or any portion thereof) at the time of Incurrence and shall only be required to include the amount and type of such Indebtedness
in one of the above clauses (provided that any Indebtedness originally classified as Incurred pursuant to any of clauses (b)(ii) through (b)(xv) of this Section 4.06 may later be reclassified as having been Incurred pursuant to
paragraph (a) or any other of clauses (b)(ii) through (b)(xv) of this Section 4.06 to the extent that such reclassified Indebtedness could be Incurred pursuant to paragraph (a) or one of clauses (b)(ii) through (b)(xv) of this
Section 4.06, as the case may be, if it were Incurred at the time of such reclassification); and 

(iii) the Issuer shall be entitled to divide and classify an item of Indebtedness in more than one of the types of
Indebtedness described above. 
 SECTION 4.07 Limitation on Restricted Payments. 

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary, directly or indirectly, to make a Restricted Payment unless at
the time the Issuer or such Restricted Subsidiary makes such Restricted Payment and immediately after giving effect to such Restricted Payment: 
 (i) no Default shall have occurred and be continuing (or would result therefrom); 
 (ii) the Issuer would, at the time of such Restricted Payment and after giving pro forma effect thereto, have been permitted to Incur at least $1.00 of additional Indebtedness pursuant to
Section 4.06(a); and 
 (iii) the aggregate amount of such Restricted Payment, together with the
aggregate amount of all other Restricted Payments (including the Fair Market Value of any non-cash amounts) made by the Issuer and its Restricted Subsidiaries since the Issue Date (including Restricted Payments permitted by
Section 4.07(b)(iii), but excluding all other Restricted Payments permitted by Section 4.07(b) would not exceed the sum of (without duplication): 

(A) 50% of the Consolidated Net Income accrued during the period (treated as one accounting period) from the beginning of
the first full fiscal quarter during which the Issue Date occurs and ending on the last day of the most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, in case such
Consolidated Net Income for such period shall be a deficit, minus 100% of such deficit); plus 

  
 -46-

 (B) 100% of the aggregate Net Cash Proceeds received by the Issuer from the
issuance or sale of its Capital Stock (other than Disqualified Stock) subsequent to the Issue Date (other than an issuance or sale to a Subsidiary of the Issuer and other than an issuance or sale to an employee stock ownership plan or to a trust
established by the Issuer or any of its Subsidiaries for the benefit of their employees) and 100% of any cash capital contribution received by the Issuer from its shareholders subsequent to the Issue Date; plus 

(C) the amount by which Indebtedness of the Issuer is reduced on the Issuer’s balance sheet upon the conversion or
exchange subsequent to the Issue Date of any Indebtedness of the Issuer convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Issuer (less the amount of any cash, or the fair value of any other property, distributed by
the Issuer upon such conversion or exchange); provided, however, that the foregoing amount shall not exceed the Net Cash Proceeds received by the Issuer or any Restricted Subsidiary from the sale of such Indebtedness (excluding Net
Cash Proceeds from sales to a Subsidiary of the Issuer or to an employee stock ownership plan or to a trust established by the Issuer or any of its Subsidiaries for the benefit of their employees); plus 

(D) an amount equal to the net reduction in the Investments (other than Permitted Investments) made by the Issuer or any
Restricted Subsidiary in any Person resulting from repurchases, repayments or redemptions of such Investments by such Person, proceeds realized on the sale of such Investment and proceeds representing the return of capital (excluding dividends and
distributions), in each case received by the Issuer or any Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any such Person, the amount of Investments (excluding Permitted Investments)
previously made (and treated as a Restricted Payment) by the Issuer or any Restricted Subsidiary in such Person; plus 
 (E) in the case of the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the portion (proportionate to the Issuer’s equity interest in such Subsidiary) of the lesser of
(x) the Fair Market Value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is redesignated as a Restricted Subsidiary and (y) such Fair Market Value as of the date on which such Subsidiary was
originally designated as an Unrestricted Subsidiary, except, in each case, to the extent that the Investment in such Unrestricted Subsidiary was made by the Issuer or a Restricted Subsidiary pursuant to Section 4.07(b)(xii) or to the
extent that such Investment constituted a Permitted Investment. 

  
 -47-

 (b) The preceding provisions shall not prohibit: 

(i) any Restricted Payment made out of the Net Cash Proceeds of the substantially concurrent sale of, or made by exchange
for, Capital Stock of the Issuer (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of the Issuer or an employee stock ownership plan or to a trust established by the Issuer or any of its Subsidiaries for the
benefit of their employees) or a substantially concurrent cash capital contribution received by the Issuer from its shareholders; provided, however, that the Net Cash Proceeds from such sale or such cash capital contribution (to the
extent so used for such Restricted Payment) shall be excluded in the calculation of amounts under Section 4.07(a)(iii)(B); 
 (ii) any purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Obligations of the Issuer or a Subsidiary Guarantor made by exchange for, or out of the
proceeds of the substantially concurrent Incurrence of, Indebtedness of such Person that is permitted to be Incurred pursuant to Section 4.06; 
 (iii) dividends paid within 60 days after the date of declaration thereof if at such date of declaration such dividend would have complied with this Section 4.07; 

(iv) so long as no Default has occurred and is continuing, (A) the purchase, redemption or other acquisition of
shares of Capital Stock of the Issuer or any of its Subsidiaries from employees, former employees, directors or former directors of the Issuer or any of its Subsidiaries (or permitted transferees of such employees, former employees, directors or
former directors), pursuant to the terms of the agreements (including employment agreements) or plans (or amendments thereto) approved or ratified by the Board of Directors under which such individuals purchase or sell or are granted the option to
purchase or sell, shares of such Capital Stock and (B) the purchase, redemption or other acquisition of shares of Capital Stock of the Issuer or any of its Subsidiaries from any Person made to mitigate the dilutive effect of the exercise of
such agreements or plans referred to in clause (A) by such employees, former employees, directors or former directors (or permitted transferees of such employees, former employees, directors or former directors); provided,
however, that the aggregate amount of such Restricted Payments (excluding amounts representing cancellation of Indebtedness) shall not exceed when taken together with all Restricted Payments made pursuant to this clause (iv), $40,000,000 and
the amount payable in any calendar year may be increased by an amount up to the sum of (i) the amount of cash proceeds from the sale of Capital Stock (other than Disqualified Stock) of the Issuer to employees, former employees, directors or
former directors of the Issuer or any of its Subsidiaries, to the extent that the cash proceeds from the sale of such Capital Stock have not otherwise been applied to the payment of Restricted Payments by virtue of
Section 4.07(a)(iii)(B), plus (ii) the cash proceeds of key man life insurance policies received by the Issuer or its Restricted Subsidiaries after the Issue Date, less (iii) the amount of repurchases and other acquisitions
previously made with the cash proceeds described in clauses (i) and (ii) above); provided further, however, that cash proceeds referred to in clause (i) above used to make Restricted Payments under this
Section 4.07(b)(iv) shall be excluded from the calculation of amounts under Section 4.07(a)(iii)(B); 
 (v) the declaration and payment of dividends on Disqualified Stock issued pursuant to Section 4.06 to the extent that such dividends are included in the definition of Consolidated Interest
Expense; provided, however, in each case, that at the time of payment of such dividend or other cash payment, no Default shall have occurred and be continuing (or result therefrom); 

(vi) repurchases of Capital Stock deemed to occur upon exercise of stock options if such Capital Stock represents a
portion of the exercise price of such options; 

  
 -48-

 (vii) cash payments in lieu of the issuance of fractional shares in
connection with the exercise of warrants, options or other securities convertible into or exchangeable for Capital Stock of the Issuer; provided, however, that any such cash payment shall not be for the purpose of evading the
limitation of this Section 4.07; 
 (viii) in the event of a Change of Control, and if no Default
shall have occurred and be continuing, the payment, purchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations of the Issuer or any Subsidiary Guarantor, in each case, at a purchase price not greater than 101% of
the principal amount of such Subordinated Obligations, plus any accrued and unpaid interest thereon; provided, however, that prior to such payment, purchase, redemption, defeasance or other acquisition or retirement, the Issuer (or a
third party to the extent permitted by this Indenture) has made a Change of Control Offer with respect to the Notes as a result of such Change of Control and has repurchased all Notes validly tendered and not withdrawn in connection with such Change
of Control Offer; 
 (ix) payments of intercompany subordinated Indebtedness, the Incurrence of which was
permitted under Section 4.06(b)(ii); provided, however, that no Default has occurred and is continuing or would otherwise result therefrom; 

(x) the payment of any dividend (or any similar distribution) by a Restricted Subsidiary of the Issuer to holders of its
Capital Stock on a pro rata basis; 
 (xi) the purchase, redemption or other acquisition or retirement for
value of shares of Capital Stock of a Restricted Subsidiary owned by a Strategic Investor if such purchase, redemption or other acquisition or retirement for value is made for consideration not in excess of the Fair Market Value of such Capital
Stock; 
 (xii) Restricted Payments in an amount that, when taken together with all Restricted Payments made
pursuant to this clause (xii) does not exceed $50,000,000; provided, however that at the time of each such Restricted Payment, no Default shall have occurred and be continuing (or result therefrom). 

The amount of any Restricted Payment that is not made in cash shall be determined in a manner consistent with the determination of the
amount of an Investment as set forth in the final sentence of the first paragraph of the definition of “Investment.” 

SECTION 4.08 Limitation on Sales of Assets and Subsidiary Stock. 

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition
unless: 
 (i) the Issuer or such Restricted Subsidiary receives consideration at the time of such Asset
Disposition at least equal to the Fair Market Value (as determined at the time of contractual agreement to such Asset Disposition) of the shares and assets subject to such Asset Disposition; 

(ii) at least 75% of the consideration thereof received by the Issuer or such Restricted Subsidiary is in the form of cash
or cash equivalents; 

  
 -49-

 (iii) an amount equal to 100% of the Net Available Cash from such Asset
Disposition, 
 (A) to the extent the Issuer elects (or is required by the terms of any Indebtedness), is used to
prepay, repay, redeem or purchase (i) Secured Indebtedness of the Issuer or a Subsidiary Guarantor or (ii) Indebtedness (other than any Disqualified Stock) of a Restricted Subsidiary that is not a Subsidiary Guarantor (in each case other
than Indebtedness owed to the Issuer or an Affiliate of the Issuer) within 450 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; 

(B) to the extent the Issuer elects (including with respect to the balance of such Net Available Cash after application
(if any) in accordance with clause (A)) within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, is used to (i) make an Investment in any one or more businesses (provided that such
Investment in any business is in the form of the acquisition of Capital Stock of such business such that such business constitutes a Restricted Subsidiary), (ii) acquire assets, (iii) acquire property, or (iv) make capital
expenditures, in each case, used or useful in a Related Business (collectively, “Additional Assets”); and 
 (C) to the extent of the balance of such Net Available Cash after application (if any) in accordance with clauses (A) and (B) and the expiration of the time periods set forth therein, to make an
offer to the Holders of the Notes (and to holders of other Pari Passu Indebtedness of the Issuer designated by the Issuer) to purchase Notes (and such other Pari Passu Indebtedness of the Issuer) pursuant to and subject to the conditions contained
in this Indenture; 
 provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness made to
satisfy clause (A) or (C) above, the Issuer or such Restricted Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount
so prepaid, repaid or purchased. 
 For the purposes of this Section 4.08, the following are deemed to be cash or
cash equivalents: 
 (i) the assumption or discharge of any liabilities (as shown on the Issuer’s or such
Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of the Issuer or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of such
assets and for which the Issuer and all of the Restricted Subsidiaries have been released by all creditors in writing; 
 (ii) securities received by the Issuer or any Restricted Subsidiary from the transferee that are converted by the Issuer or such Restricted Subsidiary within 180 days into cash, to the extent of cash
received in that conversion; 
 (iii) all Temporary Cash Investments; and 

(iv) any Designated Noncash Consideration having an aggregate Fair Market Value that, when taken together with all other
Designated Noncash Consideration previously received and then outstanding, does not exceed at the time of the receipt of such Designated Noncash Consideration (with the Fair Market Value of each item of Designated Noncash Consideration being
measured at the time received and without giving effect to subsequent changes in value) 5.0% of Total Assets. 

  
 -50-

 (b) In the event of an Asset Disposition that requires an offer to purchase the Notes (and
other Pari Passu Indebtedness of the Issuer) pursuant to Section 4.08(a)(iii)(C), the Issuer shall purchase Notes tendered pursuant to an offer by the Issuer for the Notes (and such other Pari Passu Indebtedness) at a purchase price of
100% of their principal amount (or, in the event such other Pari Passu Indebtedness of the Issuer was issued with significant original issue discount, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in
respect of such other Pari Passu Indebtedness of the Issuer, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness) in accordance with the procedures (including prorating in the event of oversubscription) set
forth in this Indenture. If the aggregate purchase price of the securities tendered pursuant to the Offer exceeds the Net Available Cash allotted to their purchase, the Issuer shall select the securities to be purchased on a pro rata basis but in
round denominations, which in the case of the Notes will be denominations of $2,000 principal amount or any greater integral multiple of $1,000. The Issuer shall not be required to make such an offer to purchase Notes (and other Pari Passu
Indebtedness of the Issuer) pursuant to this Section 4.08 if the Net Available Cash available therefor is less than $20,000,000 (which lesser amount shall be carried forward for purposes of determining whether such an offer is required
with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an offer, Net Available Cash shall be deemed to be reduced by the aggregate amount of such Offer. 

(c) (i) Promptly, and in any event within 30 days after the Issuer becomes obligated to make an Offer, the Issuer shall deliver to the
Trustee and send, by first-class mail to each Holder, a written notice stating that the Holder may elect to have his Notes purchased by the Issuer either in whole or in part (subject to prorating as described in Section 4.08(b) in the
event the Offer is oversubscribed) in amounts of $2,000 and any greater integral multiple of $1,000 of principal amount at the applicable purchase price. The notice shall specify a purchase date not less than 30 days nor more than 60 days after the
date of such notice (the “Purchase Date”). 
 (ii) Not later than the date upon which written notice of an
Offer is delivered to the Trustee as provided below, the Issuer shall deliver to the Trustee an Officers’ Certificate as to (A) the amount of the Offer (the “Offer Amount”), including information as to any other Pari Passu
Indebtedness included in the Offer for repurchase, (B) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made and (C) the compliance of such allocation with the provisions of
Section 4.08(a). By Noon New York City time on the Purchase Date, the Issuer shall irrevocably deposit with the Trustee or with a Paying Agent (or, if the Issuer or a Wholly Owned Subsidiary is acting as Paying Agent, segregate and hold
in trust) an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section 4.08. Upon the expiration of the period for which the Offer remains open (the “Offer Period”), the
Issuer shall deliver to the Trustee for cancellation the Notes or portions thereof which have been properly tendered to and are to be accepted by the Issuer. The Trustee (or the Paying Agent, if not the Trustee) shall, on the Purchase Date, mail or
deliver payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of the Notes delivered by the Issuer to the Trustee is less than the Offer Amount
applicable to the Notes, the Trustee shall deliver the excess to the Issuer immediately after the expiration of the Offer Period for application in accordance with this Section 4.08. 

(iii) Holders electing to have Notes purchased shall be required to surrender the Notes, with an appropriate form duly completed, to the
Issuer at the address specified in the notice at least three Business Days prior to the Purchase Date. A Holder shall be entitled to withdraw its election if the Trustee or the Issuer receives, not later than one Business Day prior to the Purchase
Date, a telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of the Note that was delivered for purchase by such Holder and a statement that such Holder is withdrawing its election to have such Note
purchased. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered. 

  
 -51-

 (iv) At the time the Issuer delivers Notes to the Trustee which are to be accepted for
purchase, the Issuer shall also deliver an Officers’ Certificate stating that such Notes are to be accepted by the Issuer pursuant to and in accordance with the terms of this Section 4.08. A Note shall be deemed to have been
accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. 
 (d) The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of
Notes pursuant to this Section 4.08. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuer shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this Section 4.08 by virtue of its compliance with such securities laws or regulations. 
 SECTION 4.09 Limitations on Affiliate Transactions. 
 (a) The Issuer shall
not, and shall not permit any Restricted Subsidiary to, enter into or make or amend any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements, loans, contracts, agreements or other
transactions or the rendering of any service) with, or for the benefit of, any Affiliate of the Issuer (an “Affiliate Transaction”) unless: 
 (i) the terms of the Affiliate Transaction are no less favorable to the Issuer or such Restricted Subsidiary than those that could be obtained at the time of the Affiliate Transaction in arm’s-length
dealings with a Person who is not an Affiliate; 
 (ii) if such Affiliate Transaction involves an amount in
excess of $10,000,000, the terms of the Affiliate Transaction are set forth in writing and a majority of the non-employee directors of the Issuer disinterested with respect to such Affiliate Transaction have determined in good faith that the
criteria set forth in clause (i) are satisfied and have approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and 

(iii) if such Affiliate Transaction involves an amount in excess of $75,000,000, the Board of Directors shall also have
received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Issuer and its Restricted Subsidiaries or is not less favorable to the Issuer and its
Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate. 
 (b) The provisions of Section 4.09(a) shall not prohibit: 
 (i) any Permitted Investment or any Restricted Payment, permitted to be made pursuant to Section 4.07; 
 (ii) any employment or consulting agreement, employee benefit plan, severance plans, officer or director indemnification agreement or any similar arrangement entered into by the Issuer or any of its
Restricted Subsidiaries in the ordinary course of business or as reasonably determined and in good faith approved by the Board of Directors, and payments pursuant thereto; 

(iii) loans or advances to employees in the ordinary course of business of the Issuer or its Restricted Subsidiaries, but
in any event not to exceed $10,000,000 in the aggregate outstanding at any one time;

 (iv) the payment of reasonable fees or other reasonable compensation to, or
the provision of customary benefits or indemnification arrangements to, directors of the Issuer and its Restricted Subsidiaries; 
 (v) any transaction with the Issuer, a Restricted Subsidiary or any Person that would constitute an Affiliate Transaction solely because the Issuer or a Restricted Subsidiary owns an equity interest in or
otherwise controls such Restricted Subsidiary or Person; 
 (vi) the issuance or sale of any Capital Stock (other
than Disqualified Stock) of the Issuer; 
 (vii) any agreement as in effect on the Issue Date and described in
the Offering Memorandum (or described in a document incorporated by reference in the Offering Memorandum) or any renewals or extensions of any such agreement (so long as such renewals or extensions are not less favorable in any material respect to
the Issuer or the Restricted Subsidiaries and not more disadvantageous to the Holder of the Notes in any material respect), in each case, as determined in good faith by the Issuer, and the transactions evidenced thereby; 

(viii) the provision of services to directors or officers of the Issuer or any of its Restricted Subsidiaries of the
nature provided by the Issuer or any of its Restricted Subsidiaries to customers in the ordinary course of business; and 
 (ix) transactions with joint ventures and joint venture partners (including, without limitation, physicians and other Strategic Investors), in each case, which are in the ordinary course of business
(including without limitation, pursuant to joint venture agreements) and otherwise in compliance with the terms of this Indenture. 
 SECTION 4.10 Limitations on Liens. 
 The Issuer shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, create, Incur, assume or permit to exist any Lien (the “Initial Lien”) of any nature whatsoever on any of its properties (including Capital Stock of a Restricted
Subsidiary), whether owned at the Issue Date or thereafter acquired, securing any Indebtedness, other than Permitted Liens, without effectively providing that the Notes shall be secured equally and ratably with (or prior to) the obligations so
secured for so long as such obligations are so secured. 
 Any Lien created for the benefit of the Holders of the Notes pursuant
to the preceding sentence shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. 

SECTION 4.11 Additional Subsidiary Guarantees. 
 The Issuer shall cause each Restricted Subsidiary that Guarantees any Indebtedness of the Issuer or any Subsidiary Guarantor in respect of the Credit Agreement or Capital Markets Indebtedness (or Incurs
any such Indebtedness) to, at the same time, execute and deliver to the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary will Guarantee payment of the Notes on the same terms and conditions as those set forth in Article X of
this Indenture.

 (iv) the instructions, as determined by the Issuer, consistent with this Section 4.20, that a Holder must follow in order to have its Notes purchased. 

  
 -56-

 (c) The Issuer shall not be required to make a Change of Control Offer following a Change of
Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes
validly tendered and not withdrawn under such Change of Control Offer. 
 (d) The Issuer shall comply, to the extent applicable,
with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.20. To the extent that the provisions of any securities
laws or regulations conflict with the provisions of this Section 4.20, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this
Section 4.20 by virtue thereof. 
 (e) Holders electing to have Notes purchased will be required to surrender the
Notes, with an appropriate form duly completed, to the Issuer at the address specified in the notice at least three Business Days prior to the purchase date. Holders will be entitled to withdraw their election if the Trustee or the Issuer
receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes which were delivered for purchase by the Holder and a
statement that such Holder is withdrawing his election to have such Notes purchased. 
 (f) On the purchase date, all Notes
purchased by the Issuer under this Section 4.20 shall be delivered by the Issuer to the Trustee for cancellation, and the Issuer shall pay the purchase price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

 SECTION 4.21 Suspension of Certain Covenants. 

(a) If on any date following the Issue Date (i) the Notes are rated Investment Grade by each of Moody’s and S&P (or, if
either (or both) of S&P and Moody’s have been substituted in accordance with the definition of “Ratings Agencies”, by each of the then applicable Ratings Agencies, and (ii) no Default has occurred and is continuing under this
Indenture, the Issuer and its Restricted Subsidiaries will not be subject to the provisions in the following sections (collectively, the “Suspended Covenants”): Sections 4.06, 4.07, 4.08, 4.09,
4.12, clause (a)(iii) of Section 5.01 and clauses (b) and (c) of Section.4.14. 
 (b)
During such time as the above references Sections are suspended (a “Suspension Period”), the Issuer will not be permitted to designate any Restricted Subsidiary as an Unrestricted Subsidiary. 

(c) The Issuer shall promptly upon its occurrence deliver to the Trustee an Officer’s Certificate setting forth the occurrence of
any Covenant Suspension Event or Reversion Date, and the dates thereof. The Trustee shall not have any obligation to monitor the occurrence and dates of a Covenant Suspension Event or Reversion Date and may rely conclusively on such Officer’s
Certificate. The Trustee shall not have any duty to notify the Holders of any such events or dates. 
 (d) In the event the
Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of Section 4.21(a) of the foregoing, and on any subsequent date (the “Reversion Date”) the conditions
set forth in clause (i) of Section 4.21(a) above are no longer satisfied, then the Issuer and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants with respect to future events. 

  
 -57-

 (e) On each Reversion Date, all Indebtedness incurred during the Suspension Period prior to
such Reversion Date will be deemed to be Indebtedness incurred pursuant to Section 4.06(b)(iv). For purposes of calculating the amount available to be made as Restricted Payments under Section 4.07(a)(iii), calculations under
Section 4.07 shall be made as though Section 4.07 had been in effect during the Suspension Period. Restricted Payments made during the Suspension Period not otherwise permitted pursuant under Section 4.07(b) will
reduce the amount available to be made as Restricted Payments under Section 4.07(a)(iii) to the extent such amount is a surplus. For purposes of Section 4.08, on the Reversion Date, the amount of Net Available Cash will be
reset to the amount of Net Available Cash in effect as of the first day of the Suspension Period ending on such Reversion Date. Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default shall be deemed to have
occurred as a result of a failure to comply with the Suspended Covenants during a Suspension Period (or on the Reversion Date after a Suspension Period based solely on events that occurred during the Suspension Period).

such transaction; 
 (iv) each Subsidiary Guarantor, unless it is the other party to the transactions described

(v) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating
that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture; 

  
 -58-

 provided, however, that clause (iii) shall not be applicable to (A) a Restricted

Issuer solely for the purpose and with the sole effect of reincorporating the Issuer in another jurisdiction. 
 (b) For
purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets or one or more Subsidiaries of the Issuer, which properties and assets, if

 (iii) the Subsidiary Guarantor shall
have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture

reincorporating such Guarantor in another state of the United States or the District of Columbia, so long as the amount of Indebtedness of the Subsidiary Guarantor is not increased thereby, and (2) any Subsidiary Guarantor may merge into or
transfer all or part of its properties and assets to the Issuer or another Subsidiary Guarantor.

ARTICLE VI 

DEFAULTS AND REMEDIES 
 SECTION 6.01 Events of Default.

 (b) the
Issuer (A) defaults in the payment of principal of any Note when due at its Stated Maturity, upon optional redemption of acceleration of otherwise or (B) fails to purchase Notes when required pursuant to this Indenture or the Notes;

(d) failure by the Issuer or any Subsidiary Guarantor to comply with any other agreement or covenant in this Indenture and
continuance of this failure continues for 60 days after notice of the failure has been given to the Issuer by the Trustee or by the Holders of at least 25% of the aggregate principal amount of the Notes then outstanding; 

(e) Indebtedness of the Issuer, any Subsidiary Guarantor or any Significant Subsidiary is not paid within any applicable
grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $35,000,000 or its foreign currency equivalent at the time; 

(f) any judgment or decree for the payment of money in excess of $35,000,000 (or its foreign currency equivalent at the
time) is entered against the Issuer, any Subsidiary Guarantor or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days following the entry of such judgment or decree and is not discharged, waived or effectively stayed;

 (g) the Issuer, a Subsidiary Guarantor or any Significant Subsidiary pursuant to or within the meaning of any
Bankruptcy Law: 
 (i) commences a voluntary case; 

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

(iii) consents to the appointment of a Custodian of it or for all or substantially all of its assets; or 

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

  
 -60-

Subsidiary as debtor in an involuntary case, 
 (ii) appoints a Custodian of the Issuer, any Subsidiary Guarantor
or any Significant Subsidiary or a Custodian for all or substantially all of the assets of the Issuer, any Subsidiary Guarantor or any Significant Subsidiary, or 

(iii) orders the liquidation of the Issuer, the Subsidiary Guarantor or any Significant Subsidiary, 

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

(i) any Subsidiary Guarantee ceases to be in full force and effect (other than in accordance with the terms of this
Indenture) or a Subsidiary Guarantor denies or disaffirms its obligations under the Subsidiary Guarantee. 
 The foregoing shall
constitute Events of Default whatever the reason for any such Event of Default and whether such Event of Default is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order,
rule or regulation of any administrative or governmental body. 
 The Issuer shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers’ Certificate of any Event of Default under clause (g) or (i) and any event which with the giving of notice or the lapse of time or both would become an Event of Default
under clause (d) or (h), its status and what action the Issuer is taking or proposes to take with respect thereto. 

SECTION 6.02 Acceleration. 
 (a) If any one or more of the above-described Events of Default (other than an Event of Default specified in Section 6.01(g) or 6.01(h)) shall happen with respect to Notes at the time
Outstanding, then, and in each and every such case, during the continuance of any such Event of Default, the Trustee or the Holders of 25% or more in principal amount of the Notes then Outstanding may declare the principal of and all accrued but
unpaid interest on all the Notes of such series then Outstanding to be due and payable immediately by a notice in writing to the Issuer (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 specified in Section 6.01(g) or 6.01(h) occurs and is continuing, then in every such case, the principal amount of all of the Notes then Outstanding shall
automatically, and without any declaration or any other action on the part of the Trustee or any Holder, become due and payable immediately. Upon payment of such amounts in the currency in which such Notes are denominated (subject to
Section 6.01), all obligations of the Issuer in respect of the payment of principal of and interest on the Notes of such series shall terminate. 
 (b) The Trustee shall, within 30 days after the occurrence of any Default with respect to the Notes known to it, give the Holders notice of all uncured Defaults thereunder known to it; provided,
however, that, except in the case of an Event of Default in payment with respect to the Notes or a Default in complying with Section 5.01, the Trustee shall be protected in withholding such notice if and so long as it in good
faith determines that the withholding of such notice is in the interest of the Holders. 

  
 -61-

 SECTION 6.03 Other Remedies. 

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect
the payment of principal of, or premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes and this Indenture and may take any necessary action requested of it as Trustee to settle, compromise, adjust or
otherwise conclude any proceedings to which it is a party. 
 The Trustee may maintain a proceeding even if it does not possess
any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of
or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. Any costs associated with actions taken by the Trustee under this Section 6.03 shall be reimbursed to the Trustee
by the Issuer. 
 SECTION 6.04 Waiver of Past Defaults and Events of Default. 

Subject to Sections 6.02, 6.08 and 8.02, the Holders of a majority in aggregate principal amount of the Notes then
outstanding have the right to waive any existing Default or compliance with any provision of this Indenture or 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 thereto. 
 SECTION 6.05 Control by Majority. 
 The Holders of a majority in aggregate
principal amount of the Notes then outstanding may 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 by this Indenture. The Trustee,
however, may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of another Holder not taking part in such direction or involve it in personal liability;
provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 SECTION 6.06 Limitation on Suits. 
 Except to enforce the right to receive
payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless: 
 (a) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; 
 (b) the Holders of at least 25% in principal amount of the outstanding Notes make a written request to the Trustee to pursue the remedy; 

(c) such Holder or Holders offer to the Trustee reasonable security or indemnity against any loss, liability or expense;

 (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of
security or indemnity; and 
 (e) the Holders of a majority in principal amount of the outstanding Notes do not
give the Trustee a direction inconsistent with the request during such 60-day period. 

  
 -62-

 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a
preference or priority over another Holder. In the event that the definitive Notes are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Note to issue such definitive Notes to such
beneficial owner or its nominee, the Issuer expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Notes to pursue such remedy with respect to
the portion of the Global Note that represents such beneficial holder’s Notes as if such Definitive Notes had been issued. 

SECTION 6.07 No Personal Liability of Directors, Officers, Employees and Stockholders. 

No director, officer, employee, incorporator or holder of the Capital Stock of the Issuer or any Subsidiary Guarantor shall have any
liability for any obligations of any Issuer under the Notes or this Indenture or of any Subsidiary Guarantor under its Subsidiary Guarantee or this 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 issuance of the Notes and the Subsidiary Guarantees. 

SECTION 6.08 Rights of Holders To Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, or premium, if any, and interest of the Note on or after the respective due dates
expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. 

SECTION 6.09 Collection Suit by Trustee. 
 If an Event of Default in payment of principal, premium or interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its
own name and as trustee of an express trust against the Issuer or any Subsidiary Guarantor (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued interest remaining unpaid, together with interest on overdue
principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate set forth in the Notes, and such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

SECTION 6.10 Trustee May File Proofs of Claim. 
 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07) and the Holders allowed in any judicial proceedings relative to the Issuer or any Subsidiary Guarantor (or
any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same after deduction of its
charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such

  
 -63-

 
payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. 
 To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof
out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may
be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan or reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceedings. 
 SECTION 6.11 Priorities. 
 If the Trustee collects any money pursuant to
this Article VI, it shall pay out the money in the following order: 
 FIRST: to the Trustee for amounts due
under Section 7.07; 
 SECOND: to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, and interest as to each, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes; and 
 THIRD: to the Issuer or, to the extent the Trustee collects any amount from any Subsidiary Guarantor, to such Subsidiary Guarantor. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.11. At least 15 days
before such record date, the Trustee shall mail to each Holder and the Issuer a notice that states the record date, the payment date and the amount to be paid. 
 SECTION 6.12 Undertaking for Costs. 
 In any suit for the enforcement of
any right or remedy hereunder or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and
the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section 6.12 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.08 or a suit by Holders of more than 10% in principal amount of the Notes then outstanding.

 SECTION 7.05 Notice of Defaults. Within 90 days after the occurrence thereof, and if
known to the Trustee, the Trustee shall give to the Holders a notice of each Default or Event of Default with respect to the Notes known to the Trustee, by transmitting such notice to Holders at their addresses as the same shall then appear on the
Issuer’s register, unless such Default shall have been cured or waived before the giving of such notice (the term “Default” being hereby defined to be the events specified in Section 6.01, which are, or after notice or
lapse of time or both would become, Events of Default as defined in said Section). Except in the case of a Default or Event of Default in payment of the principal of, premium, if any, or interest on any of the Notes of such series when and as the
same shall become payable, or to make any sinking fund payment as to the Notes, the Trustee shall be protected in withholding such notice, if and so long as a Responsible Officer or Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interests of the Holders of the Notes 
 SECTION 7.06 Reports by Trustee to
Holders. If required by TIA § 313(a), within 60 days after May 15th of any year, commencing May 15, 2013, the Trustee shall mail to each Holder a brief report dated as of such reporting date that complies with TIA
§ 313(a) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA
§ 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c) and TIA § 313(d). 
 Reports pursuant to this Section 7.06 shall be transmitted by mail: 
 (i) to all Holders, as the names and addresses of such Holders appear on the Registrar’s books; and 
 (ii) to such Holders as have, within the two years preceding such transmission, filed their names and addresses with the Trustee for that purpose. 

A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange on which the Notes are
listed. The Issuer shall promptly notify the Trustee, and in any event within 10 Business Days, when the Notes are listed on any stock exchange and of any delisting thereof. 
 SECTION 7.07 Compensation and Indemnity. The Issuer and the Subsidiary Guarantors shall pay to the Trustee and Agents from time to time reasonable compensation for its services hereunder (which
compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as agreed to from time to time by the Trustee and the Issuer. The Issuer and the Subsidiary Guarantors shall reimburse the
Trustee and Agents upon request for all reasonable out-of-pocket disbursements, expenses and advances incurred or made by it in connection with its duties under this Indenture, including the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel. 
 The Issuer and the Subsidiary Guarantors jointly and severally shall indemnify each of the
Trustee, any Agent and any predecessor Trustee for, and hold each of them harmless against, any and all loss, damage, claim, liability or expense, including without limitation taxes (other than taxes based on the income of the Trustee or such Agent)
and reasonable attorneys’ fees and expenses incurred by each of them in connection with the acceptance or performance of its duties under this Indenture including the reasonable costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or duties hereunder (including, without limitation, settlement costs). The Trustee or Agent shall notify the Issuer and the Subsidiary Guarantors in writing promptly of
any claim asserted against the Trustee or Agent for which it may seek indemnity. However, the failure by the Trustee or Agent to so notify the Issuer and the Subsidiary Guarantors shall not relieve the Issuer and Subsidiary Guarantors of their
obligations hereunder except to the extent the Issuer and the Subsidiary Guarantors are actually and materially prejudiced thereby. 

  
 -68-

 Notwithstanding the foregoing, the Issuer and the Subsidiary Guarantors need not reimburse
the Trustee or any Agent for any expense or indemnify it against any loss or liability incurred by the Trustee or any Agent through its negligence, bad faith or willful misconduct. To secure the payment obligations of the Issuer and the Subsidiary
Guarantors in this Section 7.07, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee except such money or property held in trust to pay principal of and interest on particular Notes.
The obligations of the Issuer and the Subsidiary Guarantors under this Section 7.07 to compensate and indemnify the Trustee, Agents and each predecessor Trustee and to pay or reimburse the Trustee, Agents and each predecessor Trustee for
expenses, disbursements and advances shall survive the resignation or removal of the Trustee and the satisfaction, discharge or other termination of this Indenture, including any termination or rejection hereof under any Bankruptcy Law. 

When the Trustee incurs expenses or renders services after an Event of Default specified in clause (g) or (h) of
Section 6.01 occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
 For purposes of this Section 7.07, the term “Trustee” shall include any trustee appointed pursuant to this Article VII. 

SECTION 7.08 Replacement of Trustee. The Trustee may resign by so notifying the Issuer and the Subsidiary Guarantors in writing.
The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee by notifying the Issuer and the removed Trustee in writing and may appoint a successor Trustee with the Issuer’s written consent, which consent shall
not be unreasonably withheld. The Issuer may remove the Trustee at its election if: 
 (i) the Trustee fails to
comply with Section 7.10; 
 (ii) the Trustee is adjudged a bankrupt or an insolvent; 

(iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a
successor Trustee. If a Trustee is removed with or without cause, all fees and expenses (including the reasonable fees and expenses of counsel) of the Trustee incurred in the administration of the trust or in performing the duties hereunder shall be
paid to the Trustee. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Issuer or the Holders of at least 10% in principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer. Immediately following such delivery, the retiring Trustee shall, subject to its 

  
 -69-

 
rights under Section 7.07, including that all sums owing to the retiring Trustee or Agent hereunder have been paid and subject to the Lien provided for in Section 7.07 of
such Section, transfer all property held by it as Trustee to the successor Trustee, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. A successor Trustee shall mail notice of its succession to each Holder. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 shall
continue for the benefit of the retiring Trustee. 
 SECTION 7.09 Successor Trustee by Consolidation, Merger, etc.

 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust
business to, another entity, subject to Section 7.10, the successor entity without any further act shall be the successor Trustee; provided such entity shall be otherwise qualified and eligible under this Article VII.

 SECTION 7.10 Eligibility; Disqualification. 
 This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1) and (2) in every respect. The Trustee (together with its corporate parent) shall have a combined
capital and surplus of at least $50,000,000 as set forth in the most recent applicable published annual report of condition. The Trustee shall comply with TIA § 310(b), including the provision in § 310(b)(1). 

SECTION 7.11 Preferential Collection of Claims Against Issuer. 

The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311 (b). A Trustee
who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 SECTION 7.12
Paying Agents. 
 The Issuer shall cause each Paying Agent other than the Trustee to execute and deliver to it and the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 7.12: 
 (A) that it will hold all sums held by it as agent for the payment of principal of, or premium, if any, or interest on, the Notes (whether such sums have been paid to it by the Issuer or by any obligor on
the Notes) in trust for the benefit of Holders or the Trustee; 
 (B) that it will at any time during the
continuance of any Event of Default, upon written request from the Trustee, deliver to the Trustee all sums so held in trust by it together with a full accounting thereof; and 

(C) that it will give the Trustee written notice within three (3) Business Days of any failure of the Issuer (or by
any obligor on the Notes) in the payment of any installment of the principal of, premium, if any, or interest on, the Notes when the same shall be due and payable.

to or consent of any Holder: 
 (i) to cure any ambiguity, omission, defect or inconsistency; 

(ii) to comply with Article V; 

(iii) to provide for uncertificated Notes in addition to or in place of certificated Notes; provided,

(iv) to add Guarantees with respect to the Notes, including any Subsidiary Guarantees, or to secure the Notes;

 (ix) to make any amendment to the
provisions of this Indenture relating to the transfer and legending of Notes; provided, however, that (A) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act
or any other applicable securities law and (B) such amendment does not materially and adversely affect the rights of Holders to transfer Notes. 
 Upon the request of the Issuer and receipt of an Officer’s Certificate and an Opinion of Counsel if requested by the Trustee, the Trustee is hereby authorized to join with the Issuer and the
Guarantors in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations which may be therein contained, but the Trustee shall not be obligated
to enter into any such supplemental indenture which adversely affects its own rights, duties or immunities under this Indenture. The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed
amendment. It is sufficient if such consent approves the substance of the proposed amendment. 
 After an amendment under this
Section 8.01 becomes effective, the Issuer shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment
under this Section 8.01. 

  
 -71-

 SECTION 8.02 With Consent of Holders. 

(a) The Issuer, the Subsidiary Guarantors and the Trustee may amend this Indenture, the Notes and any Subsidiary Guarantee with the
written consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange for, the Notes) and any past Default or compliance
with any provisions may also be waived with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding. Notwithstanding the foregoing, without the consent of each Holder affected thereby, an amendment or
waiver may not: 
 (i) reduce the amount of Notes whose Holders must consent to an amendment, supplement or
waiver; 
 (ii) reduce the rate of or extend the time for payment of interest or Additional Interest, if any, on
any Note; 
 (iii) reduce the principal of or change the Stated Maturity of any Note; 

(iv) (A) reduce the amount payable upon the redemption of any Note; or (B) change the time at which any Note may be
redeemed, in each case in accordance with Article III; 
 (v) make any Note payable in money other than
that stated in the Note; 
 (vi) impair the right of any Holder of the Notes to receive payment of principal of
and interest or Additional Interest, if any, on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes; 

(vii) make any change in the amendment provisions that require each Holder’s consent or in the waiver provisions;

 (viii) make any change in the ranking or priority of any Note that would adversely affect the Noteholders; or

 Upon the written request of the Issuer, accompanied by a Board Resolution
authorizing the execution of any such supplemental indenture, and upon the receipt by the Trustee of the documents provided for in Section 11.04 hereof if requested by the Trustee and evidence reasonably satisfactory to the Trustee of
the consent of the Holders as aforesaid and upon receipt by the Trustee of the documents described in Section 8.06, the Trustee shall join with the Issuer and the Guarantors in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee may, but shall not be obligated to, enter into such supplemental indenture. 

(b) It shall not be necessary for the consent of the Holders under this Section 8.02 to approve the particular form of any
proposed amendment, but it shall be sufficient if such consent approves the substance thereof. 
 (c) After an amendment under
this Section 8.02 becomes effective, the Issuer shall mail to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an
amendment under this Section 8.02. 

  
 -72-

 SECTION 8.03 Compliance with Trust Indenture Act. 

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

SECTION 8.04 Revocation and Effect of Consents. 
 A consent to an amendment or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting
Holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the
notice of revocation before the date on which the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon its terms following execution of such
amendment or waiver by the Trustee. 
 The Issuer may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding 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 give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 
 After an amendment, supplement, waiver or other action becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (i) through (ix) of
Section 8.02(a). In that case the amendment, supplement, waiver or other action shall bind each Holder who has consented to it and every subsequent Holder or portion of a Note that evidences the same debt as the consenting Holder’s
Note. 
 SECTION 8.05 Notation on or Exchange of Notes. 

If an amendment, supplement, or waiver changes the terms of a Note, the Trustee (in accordance with the specific written direction of the
Issuer) shall request the Holder (in accordance with the specific written direction of the Issuer) to deliver it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the
Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue, the Subsidiary Guarantors shall endorse, and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to
make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
 SECTION 8.06 Trustee To Sign Amendments, etc. 
 The Trustee shall sign any
amendment, supplement or waiver authorized pursuant to this Article VIII if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign
it. In signing or refusing to sign such amendment, supplement or waiver the Trustee shall be entitled to receive and, subject to Section 7.01, shall be fully protected in relying conclusively upon an Officers’ Certificate and an
Opinion of 

  
 -73-

 
Counsel stating, in addition to the matters required by Section 11.04, that such amendment, supplement or waiver is authorized or permitted by this Indenture and (except for
amendments permitted under Section 8.01(a)(iv) of this Indenture) the legal, valid and binding obligations of the Issuer and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary
exceptions and all conditions precedent required hereunder to such amendment, supplement or waiver have been satisfied. 

ARTICLE IX 

DISCHARGE OF INDENTURE; DEFEASANCE 
 SECTION 9.01 Discharge of Indenture. The Issuer may terminate its obligations and the obligations of the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the Registration Rights
Agreement and this Indenture, except the obligations referred to in the last paragraph of this Section 9.01, if, 
 (a) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or
segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust) have been delivered to the Trustee for cancellation, or 
 (b) (1) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or
(iii) have been called for redemption pursuant to paragraph 6 of the Notes, and, in any case the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders, U.S.
legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Indebtedness (including all principal and accrued
interest) on the Notes not theretofore delivered to the Trustee for cancellation, 
 (2) the Issuer has paid all
sums payable by them under this Indenture, and 
 (3) the Issuer has delivered irrevocable instructions to the
Trustee to apply the deposited money toward the payment of the Notes at maturity or on the date of redemption, as the case may be. 
 In addition, the Issuer must deliver an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent to satisfaction and discharge have been complied with. 

After such delivery, the Trustee shall acknowledge in writing the discharge of the Issuer’s and the Subsidiary
Guarantors’ obligations under the Notes, the Subsidiary Guarantees, the Registration Rights Agreement and this Indenture except for those surviving obligations specified below. 

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Issuer in Sections 7.01,
7.07, 9.05 and 9.06 shall survive. 
 SECTION 9.02 Legal Defeasance. 

The Issuer may at its option, by Board Resolution, be discharged from its obligations with respect to the Notes and the Subsidiary
Guarantors discharged from their obligations under the Subsidiary 

  
 -74-

 
Guarantees on the date the conditions set forth in Section 9.04 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that
the Issuer and the Subsidiary Guarantors shall be deemed to have paid and discharged the entire indebtedness represented by the Notes and the Subsidiary Guarantees with respect thereto and to have satisfied all their other obligations under such
Notes, such Subsidiary Guarantees and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Issuer, shall, subject to Section 9.06, execute instruments in form and substance reasonably satisfactory to
the Trustee and Issuer acknowledging the same, including those provided for in Section 11.04), except for the following which shall survive until otherwise terminated or discharged hereunder: 

(a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and
interest on the Notes when such payments are due solely from the trust funds described in Section 9.04 and as more fully set forth in such Section, 
 (b) the Issuer’s obligations with respect to the Notes under Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.11 and 4.18, 

(c) the rights, powers, trusts, duties, and immunities of the Trustee hereunder (including claims of, or payments to, the
Trustee under or pursuant to Sections 7.01 and 7.07) and 
 (d) this Article IX. 

Subject to compliance with this Article IX, the Issuer may exercise its option under this Section 9.02 with
respect to the Notes notwithstanding the prior exercise of their option under Section 9.03 with respect to the Notes. 
 SECTION 9.03 Covenant Defeasance. 
 At the option of the Issuer, pursuant
to a Board Resolution, (x) the Issuer and the Subsidiary Guarantors shall be released from their respective obligations under Sections 4.02 (except for obligations mandated by the TIA), 4.05 through 4.16, inclusive,
4.20 and clause (3) of the first paragraph of Section 5.01 and (y) clauses (4), (5), (6) and (9) of Section 6.01 shall no longer apply with respect to the Notes on and after the date the conditions
set forth in Section 9.04 are satisfied (hereinafter, “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that the Issuer and the Subsidiary Guarantors 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 or portion thereof, whether directly or indirectly by reason of any reference elsewhere herein to any such specified Section or portion thereof or by
reason of any reference in any such specified Section or portion thereof to any other provision herein or in any other document, but the remainder of this Indenture and the Notes shall be unaffected thereby. 

SECTION 9.04 Conditions to Legal Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of Section 9.02 or Section 9.03 to the outstanding Notes:

 (i) the Issuer must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of
the Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized firm of independent public
accountants selected by the Issuer, to pay the principal of and interest and Additional Interest, if any, on the Notes on the stated date for payment or on the Redemption Date of the principal or installment of principal of or interest on the Notes,

  
 -75-

 (ii) in the case of Legal Defeasance, the Issuer shall have delivered to the
Trustee an Opinion of Counsel in the United States confirming that: 
 (x) the Issuer has received from, or there
has been published by the Internal Revenue Service, a ruling, or 
 (y) since the Issue Date, there has been a
change in the applicable U.S. federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such Legal Defeasance had not occurred, 
 (iii) in the case of
Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax
purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred, 

(iv) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the
borrowing of funds to be applied to such deposit), 
 (v) the Legal Defeasance or Covenant Defeasance shall not
result in a breach or violation of, or constitute (a) a Default under this Indenture or (b) a default under any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any
of its Subsidiaries is bound (other than any such Default or default resulting solely from the borrowing of funds to be applied to such deposit), 
 (vi) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders over any other of their
creditors or with the intent of defeating, hindering, delaying or defrauding any other of their creditors or others, and 
 (vii) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that the conditions provided for in, in the case of the Officers’
Certificate, clauses (i) through (vi) and, in the case of the Opinion of Counsel, clauses (ii) and/or (iii) and (v) of this paragraph have been complied with. 

If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of and interest on the Notes
when due, then the obligations of the Issuer and the obligations of the Subsidiary Guarantors under this Indenture will be revived and no such defeasance will be deemed to have occurred. 

  
 -76-

 SECTION 9.05 Deposited Money and U.S. Government Obligations To Be Held in Trust; Other
Miscellaneous Provisions. 
 All money and U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 9.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any
Paying Agent, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal, premium, if any, and accrued interest, but such money need not be segregated from other funds except to the extent required by law.

 The Issuer and the Subsidiary Guarantors shall (on a joint and several basis) 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 9.04 or the principal, premium, if any, and interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes. 
 Anything in this Article IX to the contrary
notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time any money or U.S. Government Obligations held by it as provided in Section 9.04 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 an equivalent Legal Defeasance or Covenant Defeasance. 

SECTION 9.06 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01, 9.02 or 9.03 by reason of any legal proceeding or by
reason of any order or judgment of any court or Governmental Authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and each Subsidiary Guarantor’s obligations under this Indenture, the Registration Rights
Agreement, the Notes and the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article IX until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with Section 9.01; provided that if the Issuer or the Subsidiary Guarantors have made any payment of principal of, premium, if any, or accrued interest on any Notes because of the reinstatement of their
obligations, the Issuer or the Subsidiary Guarantors, as the case may be, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

 SECTION 9.07 Moneys Held by Paying Agent. 
 In connection with the satisfaction and discharge of this Indenture, all moneys then held by any Paying Agent under the provisions of this Indenture shall, upon written demand of the Issuer, be paid to
the Trustee, or if sufficient moneys have been deposited pursuant to Section 9.04, to the Issuer (or, if such moneys had been deposited by the Subsidiary Guarantors, to such Subsidiary Guarantors), and thereupon such Paying Agent shall
be released from all further liability with respect to such moneys. 
 SECTION 9.08 Moneys Held by Trustee. 

Subject to applicable law, any moneys deposited with the Trustee or any Paying Agent or then held by the Issuer or the Subsidiary
Guarantors in trust for the payment of the principal of, or premium, if any, or interest on any Note that are not applied but remain unclaimed by the Holder of such 

  
 -77-

 
Note for two years after the date upon which the principal of, or premium, if any, or interest on such Note shall have respectively become due and payable shall be repaid to the Issuer (or, if
appropriate, the Subsidiary Guarantors), or if such moneys are then held by the Issuer or the Subsidiary Guarantors in trust, such moneys shall be released from such trust; and the Holder of such Note entitled to receive such payment shall
thereafter, as an unsecured general creditor, look only to the Issuer and the Subsidiary Guarantors for the payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money shall thereupon cease;
provided that the Trustee or any such Paying Agent, before being required to make any such repayment, may, at the expense of the Issuer and the Subsidiary Guarantors, either mail to each Holder affected, at the address shown in the register
of the Notes maintained by the Registrar pursuant to Section 2.03, or cause to be published once a week for two successive weeks, in a newspaper published in the English language, customarily published each Business Day and of general
circulation in the City of New York, New York, a 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 mailing or publication, any unclaimed balance of such
moneys then remaining will be repaid to the Issuer. After payment to the Issuer or the Subsidiary Guarantors or the release of any money held in trust by the Issuer or any Subsidiary Guarantors, as the case may be, Holders entitled to the money must
look only to the Issuer and the Subsidiary Guarantors for payment as general creditors unless applicable abandoned property law designates another Person. 
 ARTICLE X 
 GUARANTEE OF NOTES 

SECTION 10.01 Guarantee. 
 (a) Each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (i) the full and punctual
payment of principal of and interest on the Notes when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligation of the Issuer under this Indenture and the Notes and (ii) the full and punctual
performance within applicable grace periods of all other obligations of the Issuer under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor
further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and such Subsidiary Guarantor will remain bound under this Article X
notwithstanding any extension or renewal of any Obligation. 
 (b) Each Subsidiary Guarantor waives presentation to, demand of,
payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of
each Subsidiary Guarantor hereunder shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce a right or remedy against the Issuer or any other Person (including any Subsidiary Guarantor)
under this Indenture, the Notes or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other
agreement; (4) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the
Guaranteed Obligations; or (6) except as set forth in Section 10.06 any change in the ownership of such Subsidiary Guarantor. 
 Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to
require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations. 

  
 -78-

 (c) Except as expressly set forth in Sections 10.02, 10.05, 10.06 and
Article IX, the obligations of such Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the
Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing
which mayor might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity. 

(d) Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein shall continue to be effective or be reinstated, as the
case may be, if at any time payment, or any part thereof, of principal of or interest on any Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

 In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in
equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise,
or to perform or comply with any other Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to
the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the
Issuer to the Holders and the Trustee. 
 (e) Each Subsidiary Guarantor agrees that it shall not be entitled to any right of
subrogation in respect of any Obligations guaranteed hereby until payment in full of all Obligations. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (A) the
maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article VI of this Indenture for the purposes of any Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (B) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article VII of this Indenture, such Guaranteed Obligations
(whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section 10.01. 
 (f) Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under
this Section 10.01. 
 SECTION 10.02 Limitation on Liability. 

Any term or provision of the Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations
guaranteed hereunder by any Subsidiary Guarantor shall 

  
 -79-

 
not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer laws restricting distributions by insolvent subsidiaries or similar laws affecting the rights of creditors generally. 
 SECTION 10.03 Successors and Assigns. 
 This Article X shall be
binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 

SECTION 10.04 No Waiver. 
 Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article X shall operate as a waiver thereof, nor shall a single
or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights,
remedies or benefits which either may have under this Article X at law, in equity, by statute or otherwise. 
 SECTION
10.05 Modification. 
 No modification, amendment or waiver of any provision of this Article X, nor the consent to
any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose
for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

SECTION 10.06 Release of Subsidiary Guarantor. 
 A Subsidiary Guarantor will be released from its obligations under this Article X: 
 (1) upon the sale or other disposition (including by way of consolidation or merger) of such Subsidiary Guarantor, including the sale or disposition of Capital Stock of such Subsidiary Guarantor,
following which such Subsidiary Guarantor is no longer a Subsidiary of the Issuer; or 
 (2) upon the sale or
disposition of all or substantially all of the assets of such Subsidiary Guarantor; 
 in each case other than to the Issuer or an Affiliate of
the Issuer and as permitted by this Indenture and if in connection therewith the Issuer provides an Officers’ Certificate to the Trustee to the effect that the Issuer will comply with its obligations under Section 4.08. in respect
of such disposition. Upon any sale or disposition described in clause (1) or (2) above, the obligor on the related Subsidiary Guarantee will be released from its obligations thereunder. 

  
 -80-

 The Subsidiary Guarantor also shall be released from its obligations under this Article
X: 
 (1) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with
the terms of this Indenture; 
 (2) at such time as any Guarantee by such Subsidiary Guarantor of the obligations
under the Credit Agreement and under all Capital Markets Indebtedness has been released and discharged, except a discharge or release by or as a result of payment under such Guarantee; or 

(3) if the Issuer exercises its legal defeasance option or its covenant defeasance option as described in Article
IX of this Indenture or if the Issuer’s obligations under this Indenture are discharged in accordance with the terms of this Indenture. 
 For avoidance of doubt, clause (2) above shall include a situation whereby the Guarantee of Capital Markets Indebtedness by a Subsidiary Guarantor, including the Notes, would be released and
discharged (“released”) immediately upon such release under the Credit Agreement but for the existence of one or more guarantees of other Capital Markets Indebtedness the terms of which also provide that such guarantees would be
released immediately upon such release under the Credit Agreement, provided that, in each case, all conditions precedent to such release have been satisfied. 
 At the request of the Issuer, the Trustee shall execute and deliver an appropriate instrument evidencing such release. 
 SECTION 10.07 Contribution. 
 Each Subsidiary Guarantor that makes a
payment under its Subsidiary Guarantee shall be titled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro
rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

 [FORM OF REVERSE OF GLOBAL INITIAL NOTE] 

AMSURG CORP. 

5.625 % SENIOR NOTE DUE 2020 
 1. Interest. AMSURG CORP., a Tennessee corporation (the “Issuer”), promises to pay, until the principal hereof is paid or made available for payment, interest (including Additional
Interest, if any) on the principal amount set forth on the face hereof at a rate of 5.625 % per annum. Interest hereon shall accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from
and including November 20, 2012 to but excluding the date on which interest is paid. Interest shall be payable in arrears on each May 30 and November 30 commencing on May 30, 2013. Interest (including Additional Interest) shall
be computed on the basis of a 360-day year of twelve 30-day months. The Issuer shall pay interest on overdue principal at 1% per annum in excess of the rate borne by the Notes and will pay interest on overdue interest at such higher rate to the
full extent permitted by law. 
 In addition to the rights provided to Holders of the Notes under the Indenture, Holders of
Registrable Notes (as defined in the Registration Rights Agreement) shall have all rights set forth in the Registration Rights Agreement, dated as of November 20, 2012, among the Issuer, the Subsidiary Guarantors named therein and the other
parties named on the signature pages thereto (the “Registration Rights Agreement”), including the right to receive Additional Interest pursuant to the Registration Rights Agreement in certain circumstances. If applicable, Additional
Interest payable pursuant to the Registration Rights Agreement shall be paid to the same Persons, in the same manner and at the same times as regular interest. 
 2. Method of Payment. The Issuer shall pay interest hereon (except defaulted interest) and Additional Interest, if any, to the Persons who are registered Holders at the close of business on
May 15 or November 15 next preceding the interest payment date (whether or not a Business Day). Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer (through the Paying Agent) shall pay principal and
interest (including Additional Interest, if any) in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. If the Holder has given wire transfer instructions to the Issuer at least
ten Business Days prior to the payment date, the Issuer shall make all payments on this Note by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on this Note shall be made by check
mailed to the Holders at their addresses set forth in the register of Holders. 
 3. Paying Agent and Registrar.
Initially, U.S. Bank National Association, a national banking association (the “Trustee”), will act as a Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent or Registrar or co-registrar without notice. Any
Issuer or any of its Affiliates may act as Paying Agent or Registrar. 
 4. Indenture. The Issuer issued the Notes under
an Indenture dated as of November 20, 2012 (the “Indenture”) among the Issuer, the Subsidiary Guarantors (as defined in the Indenture) and the Trustee. This is one of an issue of Notes of the Issuer issued, or to be issued,
under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to time. The
Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of them. Capitalized and certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture. 

  
 A-4

 5. Mandatory Redemption. The Issuer shall not be required to make mandatory
redemption payments with respect to the Notes. 
 6. Optional Redemption. 

(a) At any time or from time to time on or after November 30, 2015, the Issuer will be entitled at its option to redeem all or a
portion of the Notes (which includes Additional Notes) upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued interest and Additional
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 the relevant interest payment date), if redeemed during the twelve-month period beginning on November 30
in the years indicated below:

Holders of any outstanding Notes, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of the Indenture
under the Trust Indenture Act of 1939, as amended, and making any change that does not materially and adversely affect the rights of any Holder. Other amendments and modifications of the Indenture or the Notes may be made by the Issuer, the

principal amount of the outstanding Notes may, by written notice to the Trustee and the Issuer, and the Trustee upon the request of the Holders of not less than 25% in aggregate principal amount of the outstanding Notes shall, declare all principal

interest on, all Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in
the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. 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. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium, if any, or interest on the Notes or a default in the observance or performance of any of the
obligations of the Issuer under Article Five of the Indenture) if it determines that withholding notice is in their best interests. 
 15. Trustee Dealings with the Issuer. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may
otherwise deal with the Issuer or their Affiliates, as if it were not Trustee.

obligations pursuant to the Indenture shall be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of

principal amount of Notes of US$250,000, or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirements of law that the disposition of our
property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale
Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee

applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above prior

Guarantees” and, together with the Exchange Notes, the “Exchange Securities”), that are substantially identical in all material respects to the Notes except that the Exchange Notes (i) shall contain no restrictive
legend thereon, (ii) shall accrue interest from (A) the later of (x) the last date on which interest was paid on such Notes or (y) if such Notes are surrendered for exchange on a date in a period that includes the record date for
an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date or (B) if no such interest has been paid, from the Issue Date and (iii) shall be entitled
to the benefits of the Indenture or a trust indenture which is identical in all material respects to the Indenture (other than such changes to the Indenture or any such identical trust indenture as are necessary to comply with the TIA) and which, in
either case, has been qualified under the TIA. The Exchange Offer shall comply with all applicable tender offer rules and regulations under the Exchange Act and other applicable laws. The Company and the Guarantors shall use their respective
commercially reasonable efforts to (x) prepare and file with the SEC the Exchange Offer Registration Statement with respect to the Exchange Offer; (y) keep the Exchange Offer open for at least 20 Business Days (or longer if required by
applicable law) after the date that notice of the Exchange Offer is mailed to Holders; and (z) consummate the Exchange Offer on or prior to the 270th day following the Issue Date (the “Exchange Date”). 

Each Holder (including, without limitation, each Participating Broker-Dealer) that participates in the Exchange Offer, as a condition to
participation in the Exchange Offer, will be required to represent to the Company in writing (which may be contained in the applicable letter of transmittal) substantially to the effect that: (i) any Exchange Securities acquired in exchange for
Registrable Securities tendered are being acquired in the ordinary course of business of the Person receiving such Exchange Securities, whether or not such recipient is such Holder itself; (ii) at the time of the commencement or consummation of
the Exchange Offer neither such Holder nor, to the actual knowledge of such Holder, any other Person receiving Exchange Securities 

  
 -5-

 
from such Holder has an arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Securities in violation of the
provisions of the Securities Act; (iii) neither the Holder nor, to the knowledge of such Holder, any other Person receiving Exchange Securities from such Holder is an “affiliate” (as defined in Rule 405) of the either Company or any
Guarantor or, if it is an affiliate of either the Company or any Guarantor, it will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable and will provide information to be included in the
Shelf Registration Statement in accordance with Section 5 hereof in order to have their Securities included in the Shelf Registration Statement and benefit from the provisions regarding Additional Interest in Section 4 hereof; (iv) if
such Holder is not a broker-dealer, neither such Holder nor, to the knowledge of such Holder, any other Person receiving Exchange Securities from such Holder is engaging in or intends to engage in a distribution of the Exchange Securities; and
(v) if such Holder is a Participating Broker Dealer, such Holder has acquired the Registrable Securities for its own account in exchange for Securities that were acquired as a result of market-making activities or other trading activities and
that it will comply with the applicable provisions of the Securities Act (including, but not limited to, the prospectus delivery requirements thereunder). 
 Upon consummation of the Exchange Offer in accordance with this Section 2, the provisions of this Agreement shall continue to apply, mutatis mutandis, solely with respect to Registrable
Securities that are Private Exchange Notes (and the related Guarantees), Exchange Securities as to which Section 2(c)(3) hereof is applicable and Exchange Securities held by Participating Broker-Dealers, and the Company and the Guarantors shall
have no further obligation to register Registrable Securities (other than Private Exchange Notes (and the related Guarantees) and Exchange Securities as to which clause 2(c)(3) hereof applies) pursuant to Section 3 hereof. 

(b) The Company shall include within the Prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan
of Distribution,” which shall contain a summary statement of the positions taken or policies made by the staff of the SEC with respect to the potential “underwriter” status of any broker-dealer that is the “beneficial owner”
(as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such broker-dealer in the Exchange Offer (a “Participating Broker Dealer”), whether such positions or policies have been publicly disseminated by the
staff of the SEC or such positions or policies represent the prevailing views of the staff of the SEC. Such “Plan of Distribution” section shall also expressly permit, to the extent permitted by applicable policies and regulations of the
SEC, the use of the Prospectus by all Participating Broker-Dealers, and include a statement describing the means by which Participating Broker-Dealers may resell the Exchange Securities in compliance with the Securities Act. 

Each of the Company and the Guarantors shall use its commercially reasonable efforts to keep the Exchange Offer Registration Statement
effective and to amend and supplement the Prospectus contained therein in order to permit such Prospectus to be lawfully delivered by all Persons subject to the prospectus delivery requirements of the Securities Act for such period

  
 -6-

 
of time as is necessary to comply with applicable law in connection with any resale of the Exchange Securities; provided, however, that such period shall not be required to exceed
90 days, such period as extended, if at all, pursuant to the last paragraph of Section 5 hereof (the “Applicable Period”). 
 If, prior to consummation of the Exchange Offer, the Initial Purchasers hold any Notes acquired by them that have the status of an unsold allotment in the initial distribution, the Company, upon the
request of the Initial Purchasers, shall simultaneously with the delivery of the Exchange Notes issue and deliver to the Initial Purchasers, in exchange (the “Private Exchange”) for such Notes held by any such Holder, a like
principal amount of notes (the “Private Exchange Notes”) of the Company, guaranteed by the Guarantors, that are identical in all material respects to the Exchange Notes except for the placement of a restrictive legend on such
Private Exchange Notes. The Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the same CUSIP number as the Exchange Notes if permitted by the CUSIP Service Bureau. 

In connection with the Exchange Offer, the Company and the Guarantors shall: 

(1) mail, or cause to be mailed, to each Holder of record entitled to participate in the Exchange Offer a copy of the
Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; 
 (2) use their respective commercially reasonable efforts to keep the Exchange Offer open for not less than 20 Business Days from the date that notice of the Exchange Offer is mailed to Holders (or longer
if required by applicable law); 
 (3) utilize the services of a depositary for the Exchange Offer; 

(4) permit Holders to withdraw tendered Notes at any time prior to the close of business, New York time, on the last
Business Day on which the Exchange Offer remains open; and 
 (5) otherwise comply in all material respects with
all laws, rules and regulations applicable to the Exchange Offer. 
 As soon as practicable after the close of the Exchange
Offer and any Private Exchange, the Company and the Guarantors shall: 
 (1) accept for exchange all Registrable
Securities validly tendered and not validly withdrawn pursuant to the Exchange Offer and any Private Exchange; 

(2) deliver to the Trustee for cancellation all Registrable Securities so accepted for exchange; and 

(3) cause the Trustee to authenticate and deliver promptly to each Holder of Notes, Exchange Notes or Private Exchange
Notes, as the case may be, equal in principal amount to the Notes of such Holder so accepted for exchange; provided that, in the case of any Notes held in global form by a depositary, authentication and delivery to such depositary of one or
more replacement Notes in global form in an equivalent principal amount thereto for the account of such Holders in accordance with the Indenture shall satisfy such authentication and delivery requirement. 

  
 -7-

 The Exchange Offer and the Private Exchange shall not be subject to any conditions, other
than that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the SEC; (ii) no action or proceeding shall have been instituted or threatened in
any court or by any governmental agency which might materially impair the ability of the Company to proceed with the Exchange Offer or the Private Exchange, and no material adverse development shall have occurred in any existing action or proceeding
with respect to the Company; (iii) all governmental approvals shall have been obtained, which approvals the Company deems necessary for the consummation of the Exchange Offer or Private Exchange and (iv) the Holders shall have satisfied
customary conditions relating to the delivery of Securities and the execution and delivery of customary documentation relating to the Exchange Offer, including the representations made in Section 2(a) hereof. 

The Exchange Securities and the Private Exchange Notes (and related guarantees) shall be issued under (i) the Indenture or
(ii) an indenture substantially identical in all material respects to the Indenture and which, in either case, have been qualified under the TIA or are exempt from such qualification and shall provide that the Exchange Securities shall not be
subject to the transfer restrictions set forth in the Indenture. The Indenture or such other indenture shall provide that the Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all matters as one class and
that none of the Exchange Notes, the Private Exchange Notes or the Notes will have the right to vote or consent as a separate class on any matter. 
 If, (i) because of any change in law or in currently prevailing interpretations of the staff of the SEC, the Company or the Guarantors are not permitted to effect the Exchange Offer, (ii) the
Exchange Offer is not consummated within 270 days of the Issue Date, (iii) any holder of Private Exchange Notes so requests in writing to the Company at any time within 30 days after the consummation of the Exchange Offer, or (iv) in the
case of any Holder that participates in the Exchange Offer, such Holder does not receive Exchange Securities on the date of the exchange that may be sold without restriction under state and federal securities laws (other than due solely to the
status of such Holder as an affiliate of the Company or any Guarantor within the meaning of the Securities Act) and so notifies the Company within 30 days after such Holder first becomes aware of such restrictions (but in any event no later than 30
days after the consummation of the Exchange Offer), in the case of each of clauses (i) to and including (iv) of this sentence, then the Company and the Guarantors shall promptly deliver to the Trustee (to deliver to the Holders) written
notice thereof (the “Shelf Notice”) and shall file a Shelf Registration pursuant to Section 3 hereof. 

  
 -8-

 3. Shelf Registration 

If at any time a Shelf Notice is delivered as contemplated by Section 2(c) hereof, then: 

(a) Shelf Registration. The Company and the Guarantors shall promptly file with the SEC a Registration Statement for an offering
to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Securities (the “Initial Shelf Registration”). The Company and the Guarantors shall use their respective commercially reasonable efforts to file
with the SEC the Initial Shelf Registration on or prior to the Filing Date. The Initial Shelf Registration shall be on an appropriate form permitting registration of such Registrable Securities for resale by Holders in the manner or manners
designated by them (including, without limitation, one or more underwritten offerings). 
 The Company and the Guarantors shall
use their respective commercially reasonable efforts to cause the Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep the Initial Shelf Registration continuously effective under the
Securities Act from the date on which the Shelf Registration is declared effective by the SEC until the date that is one year following the effective date (or shorter period that will terminate when all the Registrable Securities covered by such
Shelf Registration have been sold pursuant to such Shelf Registration (the “Effectiveness Period”); provided, however, that the Effectiveness Period in respect of the Initial Shelf Registration shall be extended to the extent
required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the Securities Act and as otherwise provided herein. Notwithstanding anything to the contrary in this Agreement, at any time, the Company may
delay the filing of any Initial Shelf Registration Statement or delay or suspend the effectiveness thereof, for a reasonable period of time, but not in excess of 60 consecutive days or more than three (3) times during any calendar year (each, a
“Shelf Suspension Period”), if the Board of Directors of the Company determines reasonably and in good faith that the filing of any such Initial Shelf Registration Statement or the continuing effectiveness thereof would require the
disclosure of non-public material information that, in the reasonable judgment of the Board of Directors of the Company, would be detrimental to the Company if so disclosed or would otherwise materially adversely affect a financing, acquisition,
disposition, merger or other material transaction or if such action is required by applicable law; provided that such delay shall extend the Effectiveness Period of such Initial Shelf Registration Statement by the number of days of such Shelf
Suspension Period. 
 (b) Withdrawal of Stop Orders; Subsequent Shelf Registrations. If the Initial Shelf Registration or
any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the Securities registered thereunder), the Company and the Guarantors shall use their
respective commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall file an additional Shelf Registration Statement pursuant to Rule 415 covering all of the Registrable
Securities covered by and not sold under the Initial Shelf Registration 

  
 -9-

 
or an earlier Subsequent Shelf Registration (each, a “Subsequent Shelf Registration”). If a Subsequent Shelf Registration is filed, the Company and the Guarantors shall use their
respective commercially reasonable efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such subsequent Shelf Registration continuously effective
for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration or any Subsequent Shelf Registration was previously continuously effective. As used herein, the term
“Shelf Registration” means the Initial Shelf Registration and any Subsequent Shelf Registration. 
 (c)
Supplements and Amendments. The Company and the Guarantors shall promptly supplement and amend the Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration,
if required by the Securities Act, or if reasonably requested by the Holders of a majority in aggregate principal amount of the Registrable Securities (or their counsel) covered by such Registration Statement with respect to the information included
therein with respect to one or more of such Holders, or, if reasonably requested by any underwriter of such Registrable Securities, with respect to the information included therein with respect to such underwriter. 

4. Additional Interest 
 (a) The Company, the Guarantors and the Initial Purchasers agree that the Holders will suffer damages if the Company and the Guarantors fail to fulfill their obligations under Section 2 or
Section 3 hereof, as further specified in this Section 4 (each, a “Registration Default”), and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company and the
Guarantors agree to pay, jointly and severally, as liquidated damages, additional interest on the Notes (“Additional Interest”) if (A) the Company and the Guarantors have neither (i) exchanged Exchange Securities for all
Securities validly tendered in accordance with the terms of the Exchange Offer nor (ii) had a Shelf Registration Statement declared effective, in either case on or prior to the 270th day after the Issue Date, (B) notwithstanding clause
(A), the Company and the Guarantors are required to file a Shelf Registration Statement and such Shelf Registration Statement is not declared effective on or prior to the 60th day after the date such Registration Statement filing was requested or
required or (C), if applicable, a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period (other than because of the sale of all of the Securities registered
thereunder), then Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.25% per annum during the 90-day period immediately following the occurrence of any Registration Default (which rate will be increased by an
additional 0.25% per annum for each subsequent 90-day period that such Additional Interest continues to accrue, provided that the rate at which such Additional Interest accrues may in no event exceed 1.00% per annum) (such Additional
Interest to be calculated by the Company) commencing on the (x) 271st day after the Issue Date, in the case of (A) above, (y) the 271st day after the date such Shelf Registration Statement filing was requested or required in the case
of (B) above or (z) the day such 

  
 -10-

 
Shelf Registration ceases to be effective in the case of (C) above; provided, however, that upon the exchange of the Exchange Securities for all Securities tendered (in the
case of clause (A) of this Section 4), upon the effectiveness of the applicable Shelf Registration Statement (in the case of (B) of this Section 4), or upon the effectiveness of the applicable Shelf Registration Statement which
had ceased to remain effective (in the case of (C) of this Section 4), Additional Interest on the Notes in respect of which such events relate as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease
to accrue. Notwithstanding any other provisions of this Section 4, the Company and the Guarantors shall not be obligated to pay Additional Interest provided in Section 4(a)(B) hereof during a Shelf Suspension Period permitted by
Section 3(a) hereof. The obligation of the Company and the Guarantors to pay Additional Interest as set forth in this Section 4 shall be the sole and exclusive monetary remedy of the Holders and Participating Broker-Dealers for any
Registration Default. Notwithstanding anything to the contrary herein, (i) the amount of Additional Interest payable shall not increase because more than one Registration Default has occurred and is continuing and (ii) a Holder or
Participating Broker-Dealer that is not entitled to the benefits of the Shelf Registration shall not be entitled to Additional Interest with respect to any Registration Default that pertains to the Shelf Registration. 

(b) The Company shall notify the Trustee within five Business Days after the occurrence of a Registration Default in respect of which
Additional Interest is required to be paid. Any amounts of Additional Interest due pursuant to clause (a) of this Section 4 will be payable in cash semiannually on each May 30 and November 30 (to the holders of record on the
May 15 and November 15 immediately preceding such dates), in each case commencing with the first such date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined by the
Company by multiplying the applicable Additional Interest rate by the applicable principal amount of the Registrable Securities (as determined pursuant to Section 4(a) hereof), multiplied by a fraction, the numerator of which is the number of
days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30 day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which
is 360. 
 5. Registration Procedures 
 In connection with the filing of any Registration Statement pursuant to Section 2 or 3 hereof, the Company and the Guarantors shall use their respective commercially reasonable efforts to effect such
registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Company and the
Guarantors hereunder the Company and the Guarantors shall: 
 (a) Use their respective commercially reasonable efforts to
prepare and file with the SEC (prior to the applicable Filing Date in the case of a Shelf Registration), a Registration Statement or Registration Statements as prescribed by Section 2 or 3 hereof, and use their respective commercially
reasonable efforts to cause each such Registration Statement to become 

  
 -11-

 
effective and remain effective as provided herein; provided, however, that if (1) such filing is pursuant to Section 3 hereof or (2) a Prospectus contained in the
Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period relating thereto
from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Exchange Offer, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Company and the
Guarantors shall furnish to and afford counsel for the Holders of the Registrable Securities covered by such Registration Statement (with respect to a Registration Statement filed pursuant to Section 3 hereof) or counsel for such Participating
Broker-Dealer (with respect to any such Registration Statement), as the case may be, and counsel to the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including copies of any documents to be
incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least three Business Days prior to such filing). The Company and the Guarantors shall not file any Registration Statement or Prospectus or any
amendments or supplements thereto if the Holders of a majority in aggregate principal amount of the Registrable Securities covered by such Registration Statement, their counsel, or the managing underwriters, if any, shall reasonably object.

 (b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement or
Exchange Offer Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period, the Applicable Period or until consummation of the Exchange Offer, as the case
may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be filed pursuant to Rule 424; and comply with the provisions of the Securities Act and the Exchange Act
applicable to them with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by a
Participating Broker-Dealer covered by any such Prospectus in all material respects. The Company and the Guarantors shall be deemed not to have used their respective commercially reasonable efforts to keep a Registration Statement effective if they
voluntarily take any action that is reasonably expected to result in selling Holders of the Registrable Securities covered thereby or Participating Broker-Dealers seeking to sell Exchange Securities not being able to sell such Registrable Securities
or such Exchange Securities during that period unless such action is required by applicable law or permitted by this Agreement. 

(c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof or (2) a Prospectus contained in the Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period relating thereto from whom the
Company has received written notice that it will be a Participating Broker-Dealer in the Exchange Offer, notify the selling Holders of Registrable Securities (with respect to a Registration Statement filed pursuant to Section 3 hereof), or each
such Participating Broker-Dealer (with respect to any such Registration Statement), as the case may be, their counsel and the managing 

  
 -12-

 
underwriters, if any, promptly (but in any event within three Business Days), and confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective
amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Holder may, upon request,
obtain, at the sole expense of the Company, one conformed copy of such Registration Statement or post-effective amendment excluding financial statements and schedules, documents incorporated or deemed to be incorporated by reference and exhibits
unless specifically requested by such Holder), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the
initiation of any proceedings for that purpose, (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Registrable Securities or resales of Exchange Securities by Participating
Broker-Dealers the representations and warranties of the Company and the Guarantors contained in any agreement (including any underwriting agreement) contemplated by Section 5(m) hereof cease to be true and correct in all material respects,
(iv) of the receipt by the Company and the Guarantors of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Securities or the Exchange
Securities to be sold by any Participating Broker-Dealer for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, (v) of the happening of any event, the existence of any condition or any
information becoming known that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making
of any changes in or amendments or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and (vi) of the Company’s determination that a post-effective amendment to a Registration Statement would be
appropriate. 
 (d) Use their respective commercially reasonable efforts to prevent the issuance of any order suspending the
effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Securities or the Exchange Securities to be sold
by any Participating Broker-Dealer, for sale in any jurisdiction. 
 (e) If a Shelf Registration is filed pursuant to
Section 3 hereof and if requested during the Effectiveness Period by the managing underwriter or underwriters (if any) or the Holders of a majority in aggregate principal amount of the Registrable Securities being sold in connection with an
underwritten offering, (i) as promptly as practicable incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters (if any), such Holders or counsel for either of them
reasonably request to be included 

  
 -13-

 
therein and (ii) make all required filings of such prospectus supplement or such post-effective amendment as soon as practicable after the Company and the Guarantors have received
notification of the matters to be incorporated in such prospectus supplement or post-effective amendment. 
 (f) If (l) a
Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, furnish to each selling Holder of Registrable Securities (with respect to a Registration Statement filed pursuant to Section 3 hereof) and to each
such Participating Broker-Dealer (with respect to any such Registration Statement) and to their respective counsel and each managing underwriter, if any, upon request and at the sole expense of the Company, one conformed copy of the Registration
Statement or Registration Statements and each post-effective amendment thereto, including financial statements and schedules, and, if requested, all documents incorporated or deemed to be incorporated therein by reference and all exhibits.

 (g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the
Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, deliver to each
selling Holder of Registrable Securities (with respect to a Registration Statement filed pursuant to Section 3 hereof), or each such Participating Broker Dealer (with respect to any such Registration Statement), as the case may be, their
respective counsel, and the underwriters, if any, at the sole expense of the Company, as many copies of the Prospectus or Prospectuses (including each form of preliminary prospectus) and each amendment or supplement thereto and any documents
incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of this Section 5, the Company and the Guarantors hereby consent to the use of such Prospectus and each amendment or supplement thereto
by each of the selling Holders of Registrable Securities or each such Participating Broker-Dealer, as the case may be, and the underwriters or agents, if any, and dealers, if any, in connection with the offering and sale of the Registrable
Securities covered by, or the sale by Participating Broker-Dealers of the Exchange Securities pursuant to, such Prospectus and any amendment or supplement thereto. 
 (h) Prior to any public offering of Registrable Securities or any delivery of a Prospectus contained in the Exchange Offer Registration Statement by any Participating Broker-Dealer who seeks to sell
Exchange Securities during the Applicable Period, use their respective commercially reasonable efforts to register or qualify, and to cooperate with the selling Holders of Registrable Securities or each such Participating Broker-Dealer, as the case
may be, the managing underwriter or underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions within the United States as any selling Holder, Participating Broker-Dealer, or the managing underwriter 

  
 -14-

 
or underwriters reasonably request in writing; provided, however, that where Exchange Securities held by Participating Broker-Dealers or Registrable Securities are offered other
than through an underwritten offering, the Company and the Guarantors agree to use their respective commercially reasonable efforts to cause their counsel to perform Blue Sky investigations and file registrations and qualifications required to be
filed pursuant to this Section 5(h), keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective and do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the Exchange Securities held by Participating Broker-Dealers or the Registrable Securities covered by the applicable Registration Statement; provided, however,
that the Company and the Guarantors shall not be required to (A) qualify generally to do business in any jurisdiction where they are not then so qualified, (B) take any action that would subject them to general service of process in any
such jurisdiction where they are not then so subject or (C) subject themselves to taxation in any such jurisdiction where they are not then so subject. 
 (i) If a Shelf Registration is filed pursuant to Section 3 hereof, cooperate with the selling Holders of Registrable Securities and the managing underwriter or underwriters, if any, to facilitate the
timely preparation and delivery of certificates representing Registrable Securities to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depository Trust Company; and enable such
Registrable Securities to be in such denominations (subject to applicable requirements contained in the Indenture) and registered in such names as the managing underwriter or underwriters, if any, or Holders may reasonably request. 

(j) [Reserved]. 

(k) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, upon the occurrence of any
event contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole expense of the Company, a supplement or post-effective amendment to the
Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference so that (but only to such an extent that), as thereafter delivered to the purchasers of the Registrable Securities being sold
thereunder (with respect to a Registration Statement filed pursuant to Section 3 hereof) or to the purchasers of the Exchange Securities to whom such Prospectus will be delivered by a Participating Broker-Dealer (with respect to any such
Registration Statement), any such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under
which they were made, not misleading.

Registrable Securities, (i) if then in certificated form, provide the Trustee with certificates for the Registrable Securities in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the
Registrable Securities. 
 (m) In connection with any underwritten offering of Registrable Securities pursuant to a Shelf
Registration, enter into an underwriting agreement as is customary in underwritten offerings of debt securities similar to the Securities (including, without limitation, a customary condition to the obligations of the underwriters that the
underwriters shall have received “cold comfort” letters and updates thereof in form, scope and substance reasonably satisfactory to the managing underwriter or underwriters from the independent certified public accountants of the Company
(and, if necessary, any other independent certified public accountants of the Company, or of any business acquired by the Company, for which financial statements and financial data are, or are required to be, included or incorporated by reference in
the Registration Statement), addressed to each of the underwriters, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten offerings of debt
securities similar to the Securities), and take all such other actions as are reasonably requested by the managing underwriter or underwriters in order to expedite or facilitate the registration or the disposition of such Registrable Securities and,
in such connection, (i) make such representations and warranties to, and covenants with, the underwriters with respect to the business of the Company and the Guarantors (including any acquired business, properties or entity, if applicable), and
the Registration Statement, Prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, as are customarily made by issuers to underwriters in underwritten offerings of debt securities similar to
the Securities, and confirm the same in writing if and when reasonably requested; (ii) use their respective commercially reasonable efforts to obtain the written opinions of counsel to the Company and the Guarantors, and written updates thereof
in form, scope and substance reasonably satisfactory to the managing underwriter or underwriters, addressed to the underwriters covering the matters customarily covered in opinions reasonably requested in underwritten offerings (it being agreed that
Bass, Berry & Sims PLC is deemed to be counsel that is reasonably acceptable); and (iii) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures requested by the underwriters or no
less favorable to the sellers than those set forth in Section 7 hereof (or such other provisions and procedures reasonably acceptable to Holders of a majority in aggregate principal amount of Registrable Securities covered by such Registration
Statement and the managing underwriter or underwriters or agents, if any). The above shall be done at each closing under such underwriting agreement, or as and to the extent required thereunder. 

(n) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, make available for inspection
by any Initial Purchaser, any selling Holder of such Registrable Securities being sold (with respect to a Registration Statement filed pursuant to Section 3 hereof), or each such Participating Broker-Dealer, as the case may be, any underwriter
participating in any such disposition of Registrable 

  
 -16-

 
Securities, if any, and any attorney, accountant or other agent retained by any such selling Holder or each such Participating Broker-Dealer (with respect to any such Registration Statement), as
the case may be, or underwriter (any such Initial Purchasers, Holders, Participating Broker-Dealers, underwriters, attorneys, accountants or agents, collectively, the “Inspectors”), upon written request, at the offices where
normally kept, during reasonable business hours, all pertinent financial and other records, pertinent corporate documents and instruments of each of the Company and the Guarantors and subsidiaries of each of the Company and the Guarantors
(collectively, the “Records”), as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors and employees of the Company and the Guarantors and any of
their respective subsidiaries to supply, during reasonable business hours, all information (“Information”) reasonably requested by any such Inspector in connection with such due diligence responsibilities. Each Inspector shall agree
in writing that it will keep the Records and Information confidential, to use the Information only to the extent necessary for due diligence purposes under applicable securities laws, to abstain from using the Information as the basis for any market
transactions in Securities of the Company (or for any purpose other than the satisfaction of its due diligence responsibilities in connection with such Shelf Registration or Exchange Offer Registration Statement, as applicable) and that it will not
disclose any of the Records or Information that the Company and the Guarantors determine, in good faith, to be confidential and notifies the Inspectors in writing are confidential unless (i) the disclosure of such Records or Information is
necessary to avoid or correct a material misstatement or omission in such Registration Statement or Prospectus (in the case of any Prospectus, considered in the light of the circumstances under which it was made), (ii) the release of such
Records or Information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, (iii) disclosure of such Records or Information is necessary or advisable, in the reasonable opinion of counsel for any Inspector,
in connection with any action, claim, suit or proceeding, directly or indirectly, involving or potentially involving such Inspector and arising out of, based upon, relating to, or involving this Agreement or the Purchase Agreement, or any
transactions contemplated hereby or thereby or arising hereunder or thereunder, or (iv) the information in such Records or Information has been made generally available to the public other than by an Inspector or an “affiliate” (as
defined in Rule 405) thereof; provided, that the foregoing gathering of Records and Information by the Inspectors shall, to the greatest extent possible, be coordinated on behalf of Holders and any other parties entitled thereto (including
any Participating Broker-Dealers) by one counsel designated by them; and provided, further, that prior written notice shall be provided as soon as practicable to the Company of the potential disclosure of any information by such
Inspector pursuant to clauses (i) or (ii) of this sentence to permit the Company to obtain a protective order (or waive the provisions of this paragraph (n)) and that such Inspector shall take such actions as are reasonably necessary to
protect the confidentiality of such information to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the rights and interests of the Holder (including any Participating Broker-Dealer) or any Inspector.

 (o) Provide an indenture trustee for the Registrable Securities or the Exchange Securities, as the case may be, and cause the
Indenture or the trust indenture provided for in 

  
 -17-

 
Section 2(a) hereof, as the case may be, to be qualified under the TIA not later than the effective date of the first Registration Statement relating to the Registrable Securities; and in
connection therewith, cooperate with the trustee under any such indenture and the Holders of the Registrable Securities, to effect such changes (if any) to such indenture as may be required for such indenture to be so qualified in accordance with
the terms of the TIA; and execute, and use its commercially reasonable efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable
such indenture to be so qualified in a timely manner. 
 (p) Comply in all material respects with all applicable rules and
regulations of the SEC, and make generally available to their securityholders with regard to any applicable Registration Statement a consolidated earning statement (which need not be audited) satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) for the 12-month period beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the first
Registration Statement required by this Agreement; provided that this requirement shall be deemed satisfied by the Company by complying with the applicable reporting covenant of the Indenture. 

(q) If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Registrable Securities by Holders to the
Company (or to such other Person as directed by the Company), in exchange for the Exchange Securities or the Private Exchange Notes (and the related Guarantees), as the case may be, if then in certificated form, the Company shall mark, or cause to
be marked, on such Registrable Securities that such Registrable Securities are being cancelled in exchange for the Exchange Securities or the Private Exchange Notes (and the related Guarantees), as the case may be; in no event shall such Registrable
Securities be marked as paid or otherwise satisfied. 
 (r) Cooperate with each seller of Registrable Securities covered by any
Registration Statement and each underwriter, if any (including any “qualified independent underwriter” that is required to be retained in accordance with the rules and regulations of the Financial Industry Regulatory Authority
(“FINRA”)), participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA. 

(s) Use their respective commercially reasonable efforts to take all other steps reasonably necessary to effect the registration of the
Exchange Securities and/or Registrable Securities covered by a Registration Statement contemplated hereby. 
 The Company may
require each seller of Registrable Securities as to which any registration is being effected to furnish to the Company in writing such information regarding such seller and the distribution of such Registrable Securities as the Company may, from
time to time, reasonably request. The Company may exclude from such registration the Registrable Securities of any seller so long as such seller fails to furnish such information in writing within a

  
 -18-

 
reasonable time after receiving such request without the accrual of Additional Interest on such excluded Registrable Securities. Each seller as to which any Shelf Registration is being effected
agrees to furnish promptly in writing to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such seller not materially misleading. 

If any such Registration Statement refers to any Holder by name or otherwise as the holder of any securities of the Company, then such
Holder shall have the right to require (to the extent not objected to by the SEC) (i) the insertion therein of language, in form and substance reasonably satisfactory to such Holder, to the effect that the holding by such Holder of such
securities is not to be construed as a recommendation by such Holder of the investment quality of the securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the
Company, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar federal statute then in force, the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the time that such reference ceases to be required. 

Each Holder of Registrable Securities and each Participating Broker-Dealer agrees by its acquisition of such Registrable Securities or
Exchange Securities to be sold by such Participating Broker Dealer, as the case may be, that, upon actual receipt of any notice from the Company of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or
5(c)(vi) hereof, such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or Prospectus or Exchange Securities to be sold by such Holder or Participating Broker-Dealer, as the case may
be, until such Holder’s or Participating Broker-Dealer’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until it is advised in writing (the “Advice”) by the
Company that the use of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto. In the event that the Company shall give any such notice, each of the Applicable Period and the Effectiveness Period
shall be extended by the number of days during such periods from and including the date of the giving of such notice to and including the date when each seller of Registrable Securities covered by such Registration Statement or Exchange Securities
to be sold by such Participating Broker-Dealer, as the case may be, shall have received (x) the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or (y) the Advice. 

6. Registration Expenses. All fees and expenses incident to the performance of or compliance with this Agreement by the Company
and the Guarantors of their obligations under Sections 2, 3, 5 and 8 hereof shall be borne by the Company and the Guarantors, jointly and severally, whether or not the Exchange Offer Registration Statement or any Shelf Registration Statement is
filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with FINRA in
connection with an underwritten offering 

  
 -19-

 
and (B) fees and expenses of compliance with state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with Blue Sky
qualifications of the Registrable Securities or Exchange Securities and determination of the eligibility of the Registrable Securities or Exchange Securities for investment under the laws of such jurisdictions in the United States (x) where the
Holders of Registrable Securities are located, in the case of the Exchange Securities, or (y) as provided in Section 5(h) hereof, in the case of Registrable Securities or Exchange Securities to be sold by a Participating Broker-Dealer
during the Applicable Period)), (ii) printing expenses, including, without limitation, printing Prospectuses if the printing of Prospectuses is requested by the managing underwriter or underwriters, if any, by the Holders of a majority in
aggregate principal amount of the Registrable Securities included in any Registration Statement or in respect of Registrable Securities or Exchange Securities to be sold by any Participating Broker-Dealer during the Applicable Period, as the case
may be, (iii) fees and expenses of the Trustee and any exchange agent retained by the Company and the Guarantors and their counsel, (iv) fees and disbursements of counsel for the Company and the Guarantors and, in the case of a Shelf
Registration, fees and disbursements of one firm of counsel, plus one local counsel (if necessary) for all of the sellers of Registrable Securities (including the Initial Purchasers) selected by the Holder of a majority in aggregate principal amount
of Registrable Securities covered by such Shelf Registration (which counsel shall be reasonably satisfactory to the Company) exclusive of any counsel retained pursuant to Section 7 hereof), (v) fees and disbursements of all independent
certified public accountants referred to in Section 5(m) hereof (including, without limitation, the expenses of any “cold comfort” letters required by or incident to such performance), (vi) rating agency fees, if any, and any
fees associated with making the Registrable Securities or Exchange Securities eligible for trading through The Depository Trust Company, (vii) Securities Act liability insurance, if the Company and the Guarantors desire such insurance,
(viii) fees and expenses of all other Persons retained by the Company and the Guarantors, (ix) internal expenses of the Company and the Guarantors (including, without limitation, all salaries and expenses of officers and employees of the
Company and the Guarantors performing legal or accounting duties), (x) the expense of any annual audit, (xi) any fees and expenses incurred in connection with the obtaining of a rating of the securities and (xii) the expenses relating
to printing, word processing and distributing all Registration Statements, underwriting agreements, indentures and any other documents necessary in order to comply with this Agreement. 

7. Indemnification and Contribution. 
 (a) The Company and the Guarantors jointly and severally agree to indemnify and hold harmless each Holder of Registrable Securities and each Participating Broker-Dealer selling Exchange Securities during
the Applicable Period, and each Person, if any, who controls such Person or its affiliates within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a “Participant”) against any
losses, claims, damages or liabilities, joint or several, to which any Participant may become subject under the Securities Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon: 
 (i) any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement (or any amendment thereto) or Prospectus (as amended or supplemented if the Company or any of the Guarantors shall have furnished any amendments or supplements thereto); or 

(ii) the omission or alleged omission to state, in any Registration Statement (or any amendment thereto) or Prospectus (as
amended or supplemented if the Company or any of the Guarantors shall have furnished any amendments or supplements thereto), a material fact required to be stated therein or necessary to make the statements therein (in the case of any such
Prospectus, in the light of the circumstances under which such statement was made) not misleading; 

  
 -20-

 and agree (subject to the limitations set forth in the proviso to this sentence) to reimburse, as incurred,
the Participant for any reasonable legal or other expenses incurred by the Participant in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action;
provided, however, neither the Company nor the Guarantors will be liable in any case under this Section 7(a) to the extent that any such loss, claim, damage, or liability arises out of or is based upon any untrue statement or
omission or alleged untrue statement or alleged omission made in any Registration Statement (or any amendment thereto) or Prospectus (as amended or supplemented if the Company or any of the Guarantors shall have furnished any amendments or
supplements thereto) or any amendment or supplement thereto in reliance upon and in conformity with written information relating to any Participant furnished to the Company or the Guarantors by such Participant specifically for use therein. The
indemnity provided for in this Section 7 will be in addition to any liability that the Company or any of the Guarantors may otherwise have to the indemnified parties. The Company and the Guarantors shall not be liable under this Section 7
to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by the Company and the Guarantors, which consent shall not be unreasonably
withheld. 
 (b) Each Participant, severally and not jointly, agrees to indemnify and hold harmless the Company, the Guarantors,
their respective directors (or equivalent), their respective officers who sign any Registration Statement and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company, the Guarantors or any such director, officer or controlling person may become subject under the Securities Act, the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement
or Prospectus or any amendment or supplement thereto or (ii) the omission or the alleged omission to state therein a material fact necessary to make the statements therein not misleading (in the case of any such

  
 -21-

 
Prospectus, in the light of the circumstances under which such statements were made), in each case to the extent, but only to the extent, that such untrue statement or omission or alleged untrue
statement or alleged omission was made in reliance upon and in conformity with written information concerning such Participant furnished to the Company or the Guarantors by or on behalf of such Participant specifically for use therein; and subject
to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any reasonable legal or other expenses incurred by the Company, the Guarantors or any such director, officer or controlling person in connection with
investigating or defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action in respect thereof. The indemnity provided for in this Section 7 will be in addition to any liability
that the Participants may otherwise have to the indemnified parties. A Participant shall not be liable under this Section 7 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to
any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such
settlement, compromise or consent is consented to by such Participant, which consent shall not be unreasonably withheld. 
 (c)
Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7,
notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraphs (a) and (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying
party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local
counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party.
Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and
the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of
interest (based on the advice of counsel to the indemnified party); (ii) such action includes both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded (based on the advice of counsel to the
indemnified party) that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed
counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time 

  
 -22-

 
after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It
is understood and agreed that the indemnifying party shall not, in connection with any proceeding or separate but related or substantially similar proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm (in addition to one local counsel in each applicable jurisdiction) representing the indemnified parties under paragraph (a) or paragraph (b) of this Section 7,
as the case may be, who are parties to such action or actions. Any such separate firm for any Participants shall be designated in writing by Participants who sold a majority in interest of the Registrable Securities and Exchange Securities sold by
all such Participants in the case of paragraph (a) of this Section 7 or the Company in the case of paragraph (b) of this Section 7. An indemnifying party will not, without the prior written consent of the indemnified parties,
settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified
parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and
does not include any statement as to, or any admission of, fault, culpability or failure to act by or on behalf of any indemnified party. All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred
and following a written request therefor. 
 (d) After notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the third
sentence of paragraph (c) of this Section 7 or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying
party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent
shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 7, in which case the indemnified party may effect such a settlement without such consent. 

(e) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 7 is unavailable to,
or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) (other than for the reasons specified in Section 7(a) or 7(b) hereof, including by virtue of the
failure of an indemnified party to notify the indemnifying party of its right to indemnification pursuant to paragraph (a) or (b) of this Section 7, where such failure materially prejudices the indemnifying party (through the
forfeiture of substantial rights or defenses)), each indemnifying 

  
 -23-

 
party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities
(or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities
or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party
on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company and the
Guarantors on the one hand and the Participants on the other shall be deemed to be in the same proportion that the total net proceeds from the offering (before deducting expenses) of the Securities received by the Company bear to the total discounts
and commissions received by the Participants in connection with the initial sale of the Securities by the Company (or if such Participant did not receive a discount from the Company with respect to the initial sale of the Securities by the Company,
the net proceeds received by such Participant from the sale of Securities, Exchange Securities or Private Exchange Notes pursuant to such Registration Statement). The relative fault of the parties shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors on the one hand, or the Participants on the
other hand, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the
circumstances. The parties agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations
referred to in the first sentence of this paragraph (e). Notwithstanding any other provision of this paragraph (e), no Participant shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and
other compensation or net proceeds, as applicable, on the sale of Securities received by such Participant in connection with the sale of the Securities, less the aggregate amount of any damages that such Participant has otherwise been required to
pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (e), each person, if any, who controls a Participant within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act shall have the same rights to contribution as the Participants, and each director, member or manager, as applicable, of each of the Company and the Guarantors, each officer of each of the Company and the
Guarantors and each person, if any, who controls each of the Company and the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and
the Guarantors. 

  
 -24-

 8. Rules 144 and 144A 

The Company and the Guarantors covenant and agree that they will use their respective commercially reasonable efforts to file the reports
required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any
time the Company and the Guarantors are not required to file such reports and do not otherwise file such reports pursuant to the terms of the Indenture, the Company and the Guarantors will, upon the request of any Holder or beneficial owner of
Registrable Securities, make available such information necessary to permit sales pursuant to Rule 144A. The Company and the Guarantors further covenant and agree, for so long as any Registrable Securities remain outstanding that they will take such
further action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of
the exemptions provided by Rule 144 under the Securities Act and Rule 144A unless the Company and the Guarantors are then subject to Section 13 or 15(d) of the Exchange Act or otherwise file such reports pursuant to the terms of the Indenture
and reports filed thereunder satisfy the information requirements of Rule 144A then in effect. 
 9. Underwritten
Registrations. 
 The Company and the Guarantors shall not be required to assist in an underwritten offering unless
requested by the Holders of a majority in aggregate principal amount of the Registrable Securities. If any of the Registrable Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or
investment bankers and manager or managers that will manage the offering will be selected by the Holders of a majority in aggregate principal amount of such Registrable Securities included in such offering and shall be reasonably acceptable to the
Company and the Guarantors. 
 No Holder of Registrable Securities may participate in any underwritten registration hereunder
unless such Holder (a) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements. 
 10. Miscellaneous 
 (a) No Inconsistent Agreements. None of the
Company or the Guarantors have as of the date hereof entered, and none of the Company or the Guarantors shall after the date of this Agreement enter, into any agreement with respect to any of the Company’s securities that is inconsistent with
the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights
granted to the holders of the Company’s other issued and outstanding securities, if any, under any such agreements. 

  
 -25-

 
None of the Company or the Guarantors will enter into any agreement with respect to any of the Company’s securities which will grant to any Person piggy-back registration rights with respect
to any Registration Statement. 
 (b) Adjustments Affecting Registrable Securities. The Company shall not, directly or
indirectly, take any action with respect to the Registrable Securities as a class that would adversely affect the ability of the Company and the Guarantors to consummate the Exchange Offer on the terms specified herein or effect any Shelf
Registration required by this Agreement. 
 (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, otherwise than with the prior written consent of (I) the Company and the Guarantors, and (II) (A) the Holders of not less
than a majority in aggregate principal amount of the then outstanding Registrable Securities and (B) in circumstances that would adversely affect the Participating Broker-Dealers, the Participating Broker-Dealers holding not less than a
majority in aggregate principal amount of the Exchange Notes held by all Participating Broker-Dealers; provided, however, that Section 7 hereof and this Section 10(c) may not be amended, modified or supplemented without the
prior written consent of each Holder and each Participating Broker-Dealer (including any person who was a Holder or Participating Broker-Dealer of Registrable Securities or Exchange Securities, as the case may be, disposed of pursuant to any
Registration Statement) affected by any such amendment, modification or supplement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of
Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Securities may be given by Holders of
at least a majority in aggregate principal amount of the Registrable Securities being sold pursuant to such Registration Statement; and provided, further, that no consent is necessary from any Holder or Participating Broker-Dealer in
the event that this Agreement is amended, modified or supplemented for the purpose of curing any ambiguity, defect or inconsistency that does not adversely affect the rights of any Holder or Participating Broker-Dealer (as applicable).
