 (1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Restricted Subsidiary of such specified Person, whether or not such Indebtedness is incurred

(2) the issuance of Equity Interests in any of the Issuer’s Restricted Subsidiaries or the sale of Equity Interests

 -37-

 (2) an Officer’s Certificate from the Issuer. 

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note shall be
exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the authentication of the Regulation S Permanent Global Note, the Trustee shall cancel the
Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on the records
of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided. 

SECTION 2.02 Execution and Authentication. 
 At least one Officer must sign the Notes for the Issuer by manual or facsimile signature. 
 If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. 

A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature of the Trustee shall be conclusive
evidence that the Note has been duly authenticated under this Indenture. 
 The Trustee shall authenticate and deliver:
(i) on the Issue Date, an aggregate principal amount of $440.0 million 9.000% Senior Notes due 2020, (ii) Additional Notes for an original issue in an aggregate principal amount specified in an Authentication Order pursuant to this
Section 2.02, and (iii) Exchange Notes for issue only in an Exchange Offer pursuant to the Registration Rights Agreement, for a like principal amount of Initial Notes or Additional Notes, in each case upon a written order of the Issuer
signed by one Officer (an “Authentication Order”). Such Authentication Order shall specify the amount of the Notes to be authenticated and the date on which the original issue of the Notes is to be authenticated. 

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the
Issuer. 
 SECTION 2.03 Registrar and Paying Agent. 
 The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for
payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar”
includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer shall notify the Trustee in writing of the name and
address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

Agent and to act as Custodian with respect to the Global Notes. 
 SECTION 2.04 Paying Agent To Hold Money in Trust. 

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and shall notify the Trustee of any default by the Issuer in making any such
payment. While any such default continues, the Trustee may require in writing a Paying Agent to pay all money held by it in trust to the Trustee. The Issuer at any time may require in writing a Paying Agent to pay all money held by it in trust to
the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee shall serve as Paying Agent for the Notes. 

SECTION 2.05 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 all 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 seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and

 (3) The Registrar shall not be required to register the transfer of or exchange of any Note
selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (4) All Global

 (5) The Issuer shall not be
required: 
 (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the
opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection; 

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed

 SECTION 2.07 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee or the Registrar and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Issuer may charge for its expenses in replacing a Note. 
 Every replacement Note is an additional obligation of
the Issuer and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 SECTION 2.08 Outstanding Notes. 
 The Notes outstanding at any time are all
the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described
in this Section 2.08 as not outstanding. Subject to Section 2.09, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. 

If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under
Section 4.01, it ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the
Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease
to accrue interest. 
 SECTION 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any of its Subsidiaries, shall be considered
as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall
be so disregarded. 
 SECTION 2.10 Temporary Notes. 
 Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes (“Temporary
Notes”). Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for Temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay,
the Issuer shall prepare and the Trustee shall authenticate Definitive Notes in exchange for Temporary Notes. 
 Holders of
Temporary Notes shall be entitled to all of the benefits of this Indenture. 

  
 -52-

 SECTION 2.11 Cancellation. 
 The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and 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 dispose of such canceled Notes (subject to the record retention requirement of the
Exchange Act). Certification of the disposal of all canceled Notes shall be delivered to the Issuer upon its request therefor. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for
cancellation. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation
pursuant to this Section 2.11. 
 SECTION 2.12 Defaulted Interest. 

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01. The Issuer shall notify the Trustee in writing of the
amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be
less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall
mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 SECTION 2.13 CUSIP Numbers. 
 The Issuer in issuing the Notes may use CUSIP
numbers and corresponding ISIN numbers (if then generally in use), and, if so, the Trustee will use CUSIP numbers in notices of redemption or repurchase and other notices to Holders as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the
Notes, and any such redemption will not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee of any change in the CUSIP numbers. 
 SECTION 2.14 Issuance of Additional Notes. 
 The Issuer will be entitled,
from time to time, subject to its compliance with Section 4.08, without consent of the Holders, to issue Additional Notes under this Indenture with identical terms as the Initial Notes issued on the Issue Date other than with respect to
(i) the date of issuance, (ii) the issue price, (iii) the amount of interest payable on the first interest payment date and (iv) any adjustments in order to conform to and ensure compliance with the Securities Act (or other
applicable securities laws). The Initial Notes issued on the Issue Date, any Additional Notes and all Exchange Notes issued in exchange therefor will be treated as a single class for all purposes under this Indenture; provided that, if any
Additional Notes subsequently issued are not fungible for U.S. federal income tax purposes or securities law purposes with any Notes previously issued, such Additional Notes shall trade separately from such previously issued Notes under a separate
CUSIP number but shall otherwise be treated as a single class with all other Notes issued under this Indenture. 

  
 -53-

 With respect to any Additional Notes, the Issuer will set forth in an Officer’s
Certificate pursuant to a resolution of the Board of Directors of the Issuer, copies of which will be delivered to the Trustee, the following information: 
 (1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 

(2) the issue price, the issue date and the CUSIP number of such Additional Notes; and 

(3) whether such Additional Notes will be subject to transfer restrictions or will be issued in the form of Exchange
Notes.

national securities exchange on which the Notes are listed or (b) to the extent that selection on a pro rata basis is not practicable, by lot or by such other method the Trustee considers fair and appropriate or as required by the rules of the
Depositary; or 
 (2) if otherwise required by law. 

(b) In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be

redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in amounts of $2,000 or integral multiples of
$1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided
in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. 
 SECTION 3.03 Notice of Redemption. 
 Subject to the provisions of
Section 3.09, at least 30 days but not more than 60 days before a redemption date, the Issuer shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address,
except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 of this
Indenture. 
 The notice shall identify the Notes to be redeemed (including CUSIP Number(s)) and shall state: 

(1) the redemption date; 
 (2) the redemption price; 
 (3) if any Note is being redeemed in
part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the
original Note; 
 (4) the name and address of the Paying Agent; 

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

 (9) if the redemption is made upon an Equity Offering or in connection with a transaction (or series of related transactions ) that constitute a Change of Control or other corporate transaction, one or
more conditions precedent to the redemption, including, but not limited to, completion of an Equity Offering or Change of Control, other offering or other transaction or event. 

  
 -55-

 At the Issuer’s request, the Trustee shall give the notice of redemption in the
Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least five Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this
Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding
paragraph. 
 SECTION 3.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, except as otherwise

 SECTION 3.05 Deposit of Redemption or Purchase Price. 

On the relevant redemption or purchase date, the Issuer shall deposit with the Trustee or with the Paying Agent money sufficient to pay
the redemption or purchase price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee
or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or purchased. 

If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest and
Additional Interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or
purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01. 
 SECTION 3.06 Notes Redeemed or
Purchased in Part. 
 Upon surrender of a Note that is redeemed or purchased in part, the Issuer shall issue and, upon
receipt of an Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered; provided that each new Note
will be in denominations of $2,000 or an integral multiple of $1,000 in excess thereof. 
 SECTION 3.07 Optional Redemption.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 

SECTION 3.09 Offer To Purchase by Application of Excess Proceeds. 
 In the event that, pursuant to Section 4.09, the Issuer is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it shall follow the procedures specified
below. 
 The Asset Sale Offer shall be made to all Holders and if the Issuer elects (or is required by the terms of other Pari
Passu Indebtedness), all holders of other Indebtedness that is Pari Passu Indebtedness. The Asset Sale Offer shall remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the
extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuer shall apply all Excess Proceeds (the
“Offer Amount”) to the purchase of Notes and such other Pari Passu Indebtedness, if any, (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the
Asset Sale Offer. Payment for any Notes so purchased shall be made pursuant to Section 4.01.

record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon
the commencement of an Asset Sale Offer, the Issuer shall send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such
Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

(2) the Offer Amount, the purchase price and the Purchase Date; 

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

(4) that, unless the Issuer defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer shall cease to accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note
purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in a minimum amount of $2,000 or an integral multiple of $1,000 in excess thereof only; 

(6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer shall be required to surrender the
Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Issuer, a Depositary, if appointed by the Issuer, or a Paying Agent at the address specified in
the notice at least three days before the Purchase Date; 

  
 -57-

 (7) that Holders shall be entitled to withdraw their election if the Issuer,
the Depositary or the Paying Agent, as the case may be, receives, not later than on the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered
for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (8)
that, if the aggregate principal amount of Notes and other Pari Passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Issuer shall select the Notes and other Pari Passu Indebtedness to be purchased on a pro rata basis based
on the principal amount of Notes and such other Pari Passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof,
shall be purchased); and 
 (9) that Holders whose Notes were purchased only in part shall be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
 On or
before the Purchase Date, the Issuer shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer
Amount has been tendered, all Notes tendered, and shall deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by
the Issuer in accordance with the terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase, and the Issuer shall promptly issue a new Note, and the Trustee, upon written request from the Issuer, shall
authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered
by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Asset Sale Offer on the Purchase Date. 
 Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06.

Additional Interest, if any, on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest and Additional Interest, if any, shall be considered paid on the date due if the Paying Agent, if other than the
Issuer or a Subsidiary thereof, holds on the due date money deposited by or on behalf of the Issuer in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. The Issuer shall pay
all Additional Interest, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement.

 SECTION 4.02

the Notes and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer fails to maintain any such required office or
agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in the

 (a) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Issuer shall furnish to the Trustee and to Cede & Co., the nominee of DTC and the

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on
Forms 10-Q and 10-K, if the Issuer were required to file such Forms, including a “Management’s Discussion and Analysis of Historical Financial Condition and Results of Operations” that describes the Issuer’s consolidated
financial condition and results of operation and, with respect to the annual information only, a report thereon by the Issuer’s independent registered public accountants, and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file
such reports. 
 (b) The Issuer may satisfy its obligation to furnish such information to the Trustee and
Cede & Co. at any time by filing such information with the SEC. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Issuer will 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 those reports with the SEC. In addition, the Issuer agrees that, for so long as any Notes remain outstanding, the Issuer will furnish to any Beneficial Owner of Notes or to
any prospective purchaser of Notes in connection with any sale thereof, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

  
 -59-

 (c) If at any time Holdings (or any other direct or indirect parent company
of the Issuer) becomes a Guarantor of the Notes (there being no obligation of Holdings or any other direct or indirect parent company of the Issuer to do so), and Holdings (or such other parent company) holds no material assets other than cash, Cash
Equivalents and the Capital Stock of the Issuer, Holdings or any other direct or indirect parent company of the Issuer (and performs the related incidental activities associated with such ownership) and complies with the requirements of Rule 3-10 of
Regulation S-X promulgated by the SEC (or any successor provision), the reports, information and other documents required to be furnished to the Trustee and Cede & Co. or filed with the SEC pursuant to this Section 4.03 may, at the
option of the Issuer, be those of Holdings (or such other parent company) rather than the Issuer. 
 (d)
Notwithstanding anything herein to the contrary, the Issuer will not be deemed to have failed to comply with any of its obligations hereunder for purposes of Section 6.01(4) until 120 days after the date any report hereunder is due. To the
extent that the Issuer fails to furnish any such information within the time periods specified in this Section 4.03 and such information is subsequently furnished prior to the time such failure results in an Event of Default, the Issuer will be
deemed to have satisfied its obligations with respect thereto and any Default with respect thereto shall be deemed to have been cured. 
 (e) 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’ compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). 

SECTION 4.04 Compliance Certificate. 
 (a) The Issuer shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Issuer, an Officer’s Certificate stating that a review of the activities of the Issuer and its
Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuer has kept, observed, performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to his or her knowledge the Issuer has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance
of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or
proposes to take with respect thereto). 
 (b) So long as any of the Notes are outstanding, the Issuer shall
deliver to the Trustee, within 30 days upon any Officer becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with
respect thereto. 
 SECTION 4.05 Stay, Extension and Usury Laws. 

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

merger or consolidation involving the Issuer) any Equity Interests of the Issuer, Holdings or any other direct or indirect parent of the Issuer; 
 (C) make any payment on or with respect to, or purchase, repurchase, redeem, defease or otherwise acquire or retire for value any Subordinated Indebtedness of the Issuer or any Guarantor (excluding any

acquisition or retirement of any such Subordinated Indebtedness purchased in anticipation of satisfying a sinking fund obligation, principal installment or payment at final maturity, in each case within one year of the date of such purchase,
repurchase, redemption, defeasance or other acquisition or retirement; or 
 (D) make any Restricted Investment;

reduction thereunder pursuant to Section 4.09;

renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4) not to exceed the greater of (a) $50.0 million or (b) 2.5% of Total Assets at any time outstanding; 

(5) the incurrence by the Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness or

was permitted by this Indenture to be incurred under Section 4.08(a) or clauses (2), (3), (4), (5), (14), (16), (18), (19) or (20) of this Section 4.08(b); 

(6) the incurrence by the Issuer or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the
Issuer and any of its Restricted Subsidiaries; provided, however, that: 
 (A) if the Issuer or any
Guarantor is the obligor on such Indebtedness and the payee is not the Issuer or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of the

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

 (A) by the Issuer or any of the Guarantors of Indebtedness of the Issuer or a Restricted Subsidiary that was permitted to be incurred by another provision of this Section 4.08; provided that
if the Indebtedness being guaranteed is subordinated to the Notes, then the Guarantee shall be subordinated to the same extent as the Indebtedness guaranteed; and 

(B) by any Non-Guarantor Subsidiary of Indebtedness of a Non-Guarantor Subsidiary incurred in accordance with the terms of
this Indenture; 
 (10) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in
respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, letters of credit, performance bonds, surety bonds, appeal bonds or other similar bonds in the ordinary course of business; provided,
however, that upon the drawing of letters of credit for reimbursement obligations, including with respect to workers’ compensation claims, or the incurrence of other Indebtedness with respect to reimbursement type obligations regarding
workers’ compensation claims, such obligations are reimbursed within 30 days following such drawing or incurrence; 
 (11) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument
inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business, so long as such Indebtedness is extinguished within five Business Days; 

(12) the incurrence of Indebtedness arising from agreements of the Issuer or a Restricted Subsidiary providing for
indemnification, adjustment of purchase price, holdback, contingency payment obligations or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or Capital Stock of the
Issuer or any Restricted Subsidiary; 

  
 -70-

 (13) Indebtedness of the Issuer or any of its Restricted Subsidiaries
supported by a letter of credit issued pursuant to any Credit Facilities, in a principal amount not in excess of the stated amount of such letter of credit; 
 (14) the incurrence of Indebtedness resulting from endorsements of negotiable instruments for collection in the ordinary course of business; 

(15) Indebtedness, Disqualified Stock or preferred stock of (x) the Issuer or a Restricted Subsidiary incurred or
issued to finance an acquisition or (y) Persons that are acquired by the Issuer or any Restricted Subsidiary (including by way of merger or consolidation) in accordance with the terms of this Indenture; provided that after giving effect
to such acquisition or merger, in each case, either: 
 (A) the Issuer would be permitted to incur at least $1.00
of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio; or 
 (B) the Issuer’s Fixed Charge
Coverage Ratio after giving pro forma effect to such acquisition or merger would be greater than the Issuer’s actual Fixed Charge Coverage Ratio immediately prior to such acquisition or merger; 

(16) Indebtedness of the Issuer or a Restricted Subsidiary in respect of netting services, overdraft protection and
otherwise in connection with deposit accounts; provided that such Indebtedness remains outstanding for ten Business Days or less; 
 (17) the incurrence by a Receivables Subsidiary of Indebtedness in a Qualified Receivables Transaction; 
 (18) the incurrence or issuance by the Issuer or any of its Restricted Subsidiaries of additional Indebtedness, Disqualified Stock or preferred stock in an aggregate principal amount (or accreted value or
liquidation preference, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness and all Replacement Preferred Stock incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness, Disqualified
Stock and preferred stock incurred or issued pursuant to this clause (18), not to exceed $100.0 million; 
 (19)
the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in the form of loans from a Captive Insurance Subsidiary; and 
 (20) Indebtedness in respect of promissory notes issued to physicians, consultants, employees or directors or former employees, consultants or directors in connection with repurchases of Equity Interests
permitted by Section 4.06(b)(8). 
 For purposes of determining compliance with this Section 4.08, in the event that
an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (20) above, or is entitled to be incurred pursuant to Section 4.08(a), the Issuer shall be
permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.08 except that Indebtedness under the Credit
Agreement (including revolving credit commitments) outstanding on the Effective Date and any refinancing thereof will be deemed to have been incurred in reliance on the exception provided by clause (1) of this Section 4.08(b). The accrual
of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness 

  
 -71-

 with the same terms, the reclassification of preferred stock as Indebtedness due to a change
in accounting principles, and the payment of dividends on Disqualified Stock or preferred stock in the form of additional shares of the same class of Disqualified Stock or preferred stock shall not be deemed to be an incurrence of Indebtedness or an
issuance of Disqualified Stock or preferred stock for purposes of this Section 4.08; provided in each such case, that the amount thereof is included in Fixed Charges of the Issuer as accrued (other than the reclassification of preferred
stock as Indebtedness due to a change in accounting principles). 
 The amount of any Indebtedness outstanding as of any date
will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original
issue discount; 
 (2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the
lesser of: 
 (A) the Fair Market Value of such assets at the date of determination; and 

(B) the amount of the Indebtedness of the other Person. 

(c) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S.
dollar-equivalent principal amount of Indebtedness denominated in another currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed,
in the case of revolving credit debt; provided that if such Indebtedness is incurred to Refinance other Indebtedness denominated in another currency, and such Refinancing would cause the applicable U.S. dollar-denominated restriction to be
exceeded if calculated at the relevant currency exchange rate in effect on the date of such Refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Permitted Refinancing
Indebtedness does not exceed (i) the principal amount of such Indebtedness being Refinanced plus (ii) the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses incurred in connection with such Refinancing.

 (d) The principal amount of any Indebtedness incurred to Refinance other Indebtedness, if incurred in a different currency
from the Indebtedness being Refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such Refinancing. 

(a) The Issuer shall not, and shall not permit any Guarantor to, directly or indirectly, incur any Indebtedness that is subordinated or
junior in right of payment to any Indebtedness of the Issuer or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same
manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Guarantor, as the case may be. For purposes of this Indenture, Indebtedness that is unsecured is not deemed to be subordinated or junior to Secured Indebtedness
merely because it is unsecured, and Pari Passu Indebtedness is not deemed to be subordinated or junior to any other Pari Passu Indebtedness merely because it has a junior priority with respect to the same collateral.

 SECTION 4.09 Asset Sales. 

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, consummate, directly or indirectly,
an Asset Sale unless: 
 (1) the Issuer (or such Restricted Subsidiary, as the case may be) receives
consideration at the time of the Asset Sale at least equal to the Fair Market Value (as determined at the time of contractually agreeing to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and 

(2) at least 75% of the consideration received in the Asset Sale by the Issuer or such Restricted Subsidiary is in the
form of cash. For purposes of this paragraph (2), each of the following shall be deemed to be cash: 
 (A) Cash
Equivalents; 
 (B) any liabilities, as shown on the Issuer’s or such Restricted Subsidiary’s most
recent consolidated balance sheet or in the footnotes thereto (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets
pursuant to a customary novation agreement that releases the Issuer or such Restricted Subsidiary from further liability by all creditors; 
 (C) any securities, notes or other obligations received by the Issuer or any such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash within
180 days of receipt, to the extent of the cash received in that conversion; 
 (D) (i) any Designated
Noncash Consideration received by the Issuer or such Restricted Subsidiary in connection with the sale or contribution of assets by the Issuer or a Restricted Subsidiary to a joint venture with a Strategic Investor, provided, however,
that (x) any such Designated Noncash Consideration that is converted into Cash Equivalents shall be treated as Net Proceeds in the manner set forth below and (y) in the event such Designated Noncash Consideration is other than in the form
of Indebtedness, such Designated Noncash Consideration shall be deemed to have been acquired and consequently reduce amounts available under clause (15) or (18) of the definition of “Permitted Investments” as determined by the
Issuer and (ii) other Designated Noncash Consideration the Fair Market Value of which, when taken together with all other Designated Noncash Consideration received pursuant to this clause (ii) that is at that time outstanding, does not
exceed 5% of Total Assets at the time of 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; and 
 (E) any stock or assets of the kind referred to in clauses (5) or (7) of
Section 4.09(b). 
 Notwithstanding the foregoing, the 75% requirement referred to in clause (2) above shall not apply
to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision, is equal to or greater than what the after-tax proceeds would have been had such Asset
Sale complied with the aforementioned 75% requirement. 

  
 -73-

 (b) Within 450 days after the receipt of any Net Proceeds from an Asset
Sale, the Issuer (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds at its option: 
 (1) to repay or reduce secured Obligations under a Credit Facility to the extent such Obligations were incurred under Section 4.08(b)(1) and to correspondingly reduce commitments with respect
thereto; 
 (2) to repay or reduce Obligations under other Secured Indebtedness, which is secured by a Lien that
is permitted by this Indenture, and to correspondingly reduce commitments with respect thereto; 
 (3) to repay
or reduce other Pari Passu Indebtedness (and to correspondingly reduce commitments with respect thereto); provided that the Issuer shall reduce Obligations under the Notes on a pro rata basis by, at its option, (A) redeeming such
Notes as provided under “Optional Redemption” or (B) purchasing such Notes (i) through open-market purchases (at a price equal to or above 100% of the principal amount thereof), in a manner that complies with this Indenture and
applicable securities laws or (ii) by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but
unpaid interest, if any, and Additional Interest, if any, on the amount of notes to be purchased, to the date of repurchase; 
 (4) Indebtedness of a Non-Guarantor Subsidiary, other than Indebtedness owed to the Issuer or another Restricted Subsidiary (and to correspondingly reduce commitments with respect thereto); 

(5) to (x) acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business,
if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary or (y) make Investments pursuant to clause (15) or (18) of the definition of “Permitted
Investments;” 
 (6) to make a capital expenditure with respect to a Permitted Business; or 

(7) to acquire Additional Assets; 
 provided that the requirements of clauses (5) through (7) above shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease)
committing to make the acquisitions or expenditures referred to in any of clauses (5) through (7) above is entered into by the Issuer or such Restricted Subsidiary within 450 days after the receipt of such Net Proceeds with the good faith
expectation that such Net Proceeds will be applied to satisfy such commitment in accordance with such agreement within 180 days of such commitment and if such Net Proceeds are not so applied within such 180 day period, then such Net Proceeds shall
constitute Excess Proceeds (as defined below). 
 Pending the final application of any Net Proceeds pursuant to this
Section 4.09, the holder of such Net Proceeds may apply such Net Proceeds to temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. 

  
 -74-

 (c) Any Net Proceeds from Asset Sales that are not applied or invested as
provided in Section 4.09(b) shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, within ten Business Days thereof, the Issuer shall make an Asset Sale Offer to all Holders and if the
Issuer elects (or is required by the terms of such other Pari Passu Indebtedness), all holders of such Pari Passu Indebtedness. The offer price in any Asset Sale Offer shall be equal to 100% of the principal amount plus accrued and unpaid interest
and Additional Interest, if any, to the date of purchase, and shall be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use those Excess Proceeds for any purpose not otherwise prohibited by
this Indenture. If the aggregate principal amount of Notes and other Pari Passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Issuer shall select the Notes and such other Pari Passu Indebtedness to be
purchased on a pro rata basis. In the event that the Issuer or a Restricted Subsidiary prepays any Pari Passu Indebtedness that is outstanding under a revolving credit or other committed loan facility pursuant to an Asset Sale Offer, the Issuer or
such Restricted Subsidiary shall cause the related loan commitment to be reduced in an amount equal to the principal amount so prepaid. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 

(d) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the
provisions of Section 3.09 or this Section 4.09, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Section 3.09 or this Section 4.09 by
virtue of such compliance. 
 SECTION 4.10 Transactions with Affiliates. 

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of,
any Affiliate of the Issuer involving aggregate consideration in excess of $5.0 million (each, an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that, taken as a whole, are not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person; and 
 (2) with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, the Issuer delivers to the Trustee a resolution adopted by the majority of the members of the Board of
Directors of the Issuer approving such Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) above. 

(b) The following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the
provisions of Section 4.10(a): 
 (1) any employment agreement, employee benefit plan, 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 and payments pursuant thereto; 

  
 -75-

 (2) transactions between or among the Issuer and/or its Restricted
Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary of the Issuer) that is an
Affiliate of the Issuer solely because the Issuer owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (4) payment of reasonable directors’ fees; 
 (5) any issuance
of Equity Interests (other than Disqualified Stock) of the Issuer to Affiliates of the Issuer; 
 (6) Permitted
Investments or Restricted Payments that do not violate Section 4.06;

(9) loans (or cancellation of loans) or advances to employees in the ordinary course of business; 

(10) transactions with customers, suppliers, contractors, joint venture partners or purchasers or sellers of goods or
services, 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, and which are fair to the Issuer or its
Restricted Subsidiaries, as applicable, in the reasonable determination of the Board of Directors, chief executive officer or chief financial officer of the Issuer or its Restricted Subsidiaries, as applicable, or are on terms at least as favorable
as might reasonably have been obtained at such time from an unaffiliated party; 
 (11) the existence of, or the
performance by the Issuer or any Restricted Subsidiary of their obligations, if any, or obligations of Holdings under the terms of, any subscription, registration rights or stockholders agreement, partnership agreement or limited liability company
agreement to which Holdings, the Issuer or any Restricted Subsidiary is a party as of the Effective Date and which is disclosed in the Offering Memorandum under the caption “Certain Relationships and Related Party Transactions” and any
similar agreements which the Issuer, any Restricted Subsidiary, Holdings or any other direct or indirect parent company of the Issuer may enter into thereafter; provided, however, that the entering into by the Issuer or any Restricted
Subsidiary or the performance by the Issuer or any Restricted Subsidiary of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Effective Date will only be permitted by this
clause to the extent that the terms of any such amendment or new agreement, taken as a whole, are not materially disadvantageous to the Holders, as determined in good faith by the Board of Directors, chief executive officer or chief financial
officer of the Issuer; 

  
 -76-

a Receivables Subsidiary effected as part of a Qualified Receivables Transaction; 
 (14) Permitted Payments to
Parent; 
 (15) any management, consulting, monitoring, advisory, financing, underwriting or placement services
or any other investment banking, banking or similar services involving the Issuer and any of its Restricted Subsidiaries (including without limitation any payments in cash, Equity Interests or other consideration made by the Issuer or any of its
Restricted Subsidiaries in connection therewith) on the one hand and the Permitted Holders on the other hand, which services (and payments and other transactions in connection therewith) are approved as fair to the Issuer or such Restricted

any amendment thereto (so long as such amendment is not disadvantageous to the Holders in any material respect). 
 SECTION 4.11 Liens.

 The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to create, incur, assume or otherwise cause or
suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless 

  
 -77-

 (a) in the case of Liens securing Subordinated Indebtedness, the Notes and
related Guarantees are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; and 
 (b) in all other cases, all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured. 

Any Lien created for the benefit of the Holders pursuant to the preceding paragraph shall provide by its terms that such Lien shall be
automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to the obligation to secure the Notes. 
 SECTION 4.12 Corporate Existence. 
 Subject to Article 5, the Issuer shall
do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence in accordance with its organizational documents (as the same may be amended from time to time). 

SECTION 4.13 Offer To Repurchase Upon Change of Control. 
 (a) If a Change of Control occurs after the Effective Date, each Holder shall have the right to require the Issuer to make an offer (a “Change of Control Offer”) to repurchase all or any part
(equal to $2,000 or an integral multiple of $1,000) of that Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased to
the date of purchase subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Issuer
shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to this Section 4.13 and that all Notes tendered shall be accepted for payment; 

(2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the
date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not tendered
shall continue to accrue interest; 
 (4) that, unless the Issuer defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest and Additional Interest after the Change of Control Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender
the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the
third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders shall be entitled to
withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; 

  
 -78-

 (7) that Holders whose Notes are being purchased only in part shall be
issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof; and 

(8) that Holders electing to have a Note purchased pursuant to a Change of Control Offer may elect to have Notes purchased
in a minimum amount of $2,000 or an integral multiple of $1,000 in excess thereof only. 
 The Issuer shall comply with the
requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of Sections 3.09 or 4.13 of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have
breached its obligations under Section 3.09 or this Section 4.13 by virtue of such compliance. 
 (b)
On the Change of Control Payment Date, the Issuer shall, to the extent lawful: 
 (1) accept for payment all
Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the
Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased
by the Issuer. 
 The Paying Agent shall promptly mail (but in any case not later than five days after the Change of Control
Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount
to any unpurchased portion of the Notes surrendered, if any. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

(c) Notwithstanding anything to the contrary in this Section 4.13, the Issuer shall not be required to make a Change
of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.13 and purchases all Notes validly
tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 of this Indenture, unless and until there is a Default in payment of the applicable redemption price. A
Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer. 

  
 -79-

 (d) Other than as specifically provided in this Section 4.13, any
purchase pursuant to this Section 4.13 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06 hereof. 
 SECTION 4.14
Designation of Restricted and Unrestricted Subsidiaries. 
 The Board of Directors of the Issuer may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the
Issuer and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of the designation and shall reduce the amount available for Restricted Payments under
Section 4.06 or under one or more clauses of the definition of Permitted Investments, as determined by the Issuer. That designation shall only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. 
 Any designation of a Subsidiary of the Issuer as an
Unrestricted Subsidiary shall be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors of the Issuer giving effect to such designation and an Officer’s Certificate certifying that such
designation complied with the preceding conditions and was permitted by Section 4.06. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under
Section 4.08, the Issuer shall be in Default of Section 4.08. The Board of Directors of the Issuer may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation shall be deemed
to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation shall only be permitted if such Indebtedness is permitted under Section 4.08 and no Default or
Event of Default would be in existence following such designation. 
 SECTION 4.15 Payments for Consent. 

The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders
that are QIBs, who, upon request, confirm that they QIBs, that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment. 

SECTION 4.16 Additional Subsidiary Guarantees. 
 If the Issuer or any of its Restricted Subsidiaries, acquires or creates another Subsidiary, other than a Non-Guarantor Subsidiary, after the Effective Date that incurs or guarantees Indebtedness of the
Issuer or any Guarantor under the Credit Agreement, then that newly acquired or created Subsidiary shall become a Guarantor and execute a supplemental indenture substantially in the form attached as Exhibit E and deliver an Opinion of Counsel
to the Trustee within 30 Business Days of the date on which such guarantee was created. 

  
 -80-

 SECTION 4.17 Distributions by Qualified Restricted Subsidiaries. 

Except to the extent restricted pursuant to any Permitted Payment Restrictions, the Issuer shall cause each, and shall cause each
Restricted Subsidiary that is the parent of a Qualified Restricted Subsidiary to declare and pay regular monthly, quarterly or semiannual dividends or distributions to the holders of its Capital Stock in an amount equal to substantially all of the
available cash flow of such Restricted Subsidiary for such period as determined in good faith by the board of directors, board of governors or such other individuals performing similar functions, subject to such ordinary and customary reserves and
other amounts as, in the good faith judgment of such individuals, may be necessary so that the business of such Restricted Subsidiary may be properly and advantageously conducted at all times. 

If, at any time, any Restricted Subsidiary would fail to meet the requirements set forth in the definition of “Qualified Restricted
Subsidiary,” it will thereafter cease to be a Qualified Restricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary that is not a Qualified Restricted
Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.08, the Issuer will be in default of such covenant. The Board of Directors of the Issuer may at any time designate any
Restricted Subsidiary not to be a Qualified Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by such Restricted Subsidiary of any outstanding Indebtedness of such Restricted Subsidiary,
and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.08 and (2) no Default or Event of Default would be in existence following such designation. In the event (x) a Restricted
Subsidiary fails to meet the requirements to be a Qualified Restricted Subsidiary or (y) the Board of Directors designates a Qualified Restricted Subsidiary not to be a Qualified Restricted Subsidiary, then all Investments in such Subsidiary
since the Effective Date shall be deemed to have been acquired and consequently reduce the amount available for Restricted Payments under Section 4.06 or the amount available for Restricted Investments under clauses (15) or (18) of
the definition of “Permitted Investments” as determined by the Issuer. As of the Effective Date, all of the Issuer’s Restricted Subsidiaries will be Qualified Restricted Subsidiaries. 

SECTION 4.18 Discharge and Suspension of Covenants. 
 (a) After the Effective Date, during any period of time that: (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is continuing under this
Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the Issuer and the Restricted Subsidiaries will not be subject to
Section 4.06 hereof, Section 4.07 hereof, Section 4.08 hereof, Section 4.09 hereof, Section 4.10 hereof and 5.01(a)(4) hereof (the “Suspended Covenants”). Upon the occurrence of a Covenant Suspension Event (the
date of such occurrence, the “Suspension Date”), the amount of Excess Proceeds from Net Proceeds shall be set at zero. 
 (b) In the event that the Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the
“Reversion Date”) one or both of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Notes below an Investment Grade Rating or a Default or an Event of Default occurs and is continuing, then
the Issuer and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants with respect to future events under this Indenture. The period of time between the Suspension Date and the Reversion Date is referred to in this
description as the “Suspension Period.” Notwithstanding that the Suspended Covenants may be reinstated, no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the Registration Rights Agreement,
the Notes or the Subsidiary Guarantees with respect to the Suspended Covenants, and none 

  
 -81-

 
of the Issuer or any of its Subsidiaries shall bear any liability for any actions taken or events occurring during the Suspension Period, or any actions taken at any time pursuant to any
contractual obligation arising prior to the Reversion Date, as a result of a failure to comply with the Suspended Covenants during the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that
occurred during the Suspension Period). 
 (c) On the Reversion Date, all Indebtedness incurred, or Disqualified
Stock issued, during the Suspension Period will be classified to have been incurred or issued pursuant to Section 4.08(b)(2). On the Reversion Date, all Liens created, incurred or assumed during the Suspension Period in compliance with this
Indenture will be deemed to have been outstanding on the Effective Date, so that they are classified as permitted under clause (6) of the definition of “Permitted Liens.” Calculations made after the Reversion Date of the amount
available to be made as Restricted Payments under Section 4.06 will be made as though Section 4.06 had been in effect prior to, but not during, the Suspension Period. No Subsidiaries shall be designated as Unrestricted Subsidiaries during
any Suspension Period. 
 (d) The Issuer shall deliver promptly to the Trustee an Officer’s Certificate
notifying it of any such occurrence under this Section 4.18. 
 SECTION 4.19 Activities Prior to the Merger. 

(a) USPI Finance is a limited purpose corporation. Prior to the consummation of the Merger, USPI Finance’s primary
activities will be restricted to issuing the Notes, issuing Capital Stock to, and receiving capital contributions from, USPI Group Holdings, Inc., performing its obligations in respect of the Notes under this Indenture, performing its obligations
under the merger agreement between USPI Finance and USPI, consummating the Transactions and Release and redeeming the Notes, if applicable, and conducting such other activities as are necessary or appropriate to carry out the activities described
above. 
 (b) Prior to the consummation of the Merger, USPI Finance and its Restricted Subsidiaries shall not
engage in any business activity or enter into any transaction or agreement (including, without limitation, making any restricted payment, incurring any debt, incurring any Liens except in favor of the Holders, entering into any merger, consolidation
or sale of all or substantially all of its assets or engaging in any transaction with its Affiliates) except in the ordinary course of business or necessary to effectuate the Merger and the Transactions substantially in accordance with the
description of the Transactions set forth in the Offering Memorandum, together with such amendments, modifications and waivers that are not, individually or in the aggregate, materially adverse to USPI and its Subsidiaries (after giving effect to
the consummation of the Transactions), taken as a whole, or to the Holders.

Person, as the case may be, being herein called the “Successor Person”); 
 (B) the Successor Person,
if other than such Guarantor, expressly assumes all the obligations of such Guarantor under this Indenture, the Registration Rights Agreement and such Guarantor’s related Subsidiary Guarantee pursuant to supplemental indentures or other

States, any state thereof, the District of Columbia or any territory thereof so long as the amount of Indebtedness of the Issuer and its Restricted Subsidiaries is not increased thereby or (iii) convert into a Person organized or existing under
the laws of the jurisdiction of such Guarantor or the laws of another jurisdiction in the United States. 
 SECTION 5.02 Successor
Corporation Substituted. 
 Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the assets of the Issuer in a transaction that is subject to, and that complies with the provisions of, Section 5.01, the successor Person formed by such consolidation or into or with which the Issuer
is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease,
conveyance or other disposition, the provisions of this Indenture referring to the “Issuer” shall refer instead to the successor Person and not to the Issuer), and may exercise every right and power of the Issuer under this Indenture with
the same effect as if such successor Person had been named as the Issuer herein, and when a successor Person assumes all obligations of its predecessor under this Indenture or the Notes, the predecessor shall be released from those obligations;

is created after the Effective Date, if that default: 
 (A) is caused by a failure to pay principal at the final
Stated Maturity of such Indebtedness (a “Payment Default”); or 
 (B) results in the acceleration of
such Indebtedness prior to its express maturity; 
 and, in each case, the principal amount of such Indebtedness, together with

the Issuer or such Significant Subsidiary, as applicable, to pay such judgment or decree, which judgment or decree has remained outstanding for a period of 60 days after such judgment or decree became final and nonappealable without being paid,
discharged, waived or stayed; 

  
 -85-

 (7) except as permitted by this Indenture, any Subsidiary Guarantee of any
Significant Subsidiary is declared to be unenforceable or invalid by any final and nonappealable judgment or decree or ceases for any reason to be in full force and effect, or any Guarantor that is a Significant Subsidiary or any Person acting on
behalf of any Guarantor that is a Significant Subsidiary denies or disaffirms its obligations in writing under its Subsidiary Guarantee and such Default continues for 10 days after receipt of notice thereof by the Trustee or the Holders of at least

discharged; 
 (2) holders thereof have rescinded or waived the acceleration, notice or action (as the case may
be) giving rise to such Event of Default; or 
 (3) the default that is the basis for such Event of Default has

 SECTION 6.02 Acceleration. 

In the case of an Event of Default arising under clause (8) or (9) of Section 6.01, all outstanding Notes
shall become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all
the Notes to be due and payable immediately; 
 Upon any such declaration, the Notes shall become due and payable immediately.
The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration or waive any existing Default or Event of Default and its
consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium or Additional Interest, if any, on, or the principal of, the Notes. 
 SECTION 6.03 Other Remedies. 
 If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium and Additional Interest, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All
remedies are cumulative to the extent permitted by law. 
 SECTION 6.04 Waiver of Past Defaults. 

Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of interest on, premium, if any, Additional Interest, if any, or the principal of any Note
held by a non-consenting Holder (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its
consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of
this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. In case of any such waiver, the Issuer, the Trustee and the Holders shall be restored to their former positions and rights
hereunder and under the Notes, respectively. 
 SECTION 6.05 Control by Majority. 

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to reasonable indemnification against all losses and expenses caused by
taking or not taking such action. 

  
 -87-

 SECTION 6.06 Limitation on Suits. 

A Holder may pursue a remedy with respect to this Indenture or the Notes only if: 

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to
pursue the remedy; 
 (3) such Holders have offered the Trustee reasonable security or indemnity against any
loss, liability or expense; 
 (4) the Trustee has not complied with such request within 60 days after the
receipt of the request and the offer of security or indemnity; and 
 (5) Holders of a majority in aggregate
principal amount of the then outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 

SECTION 6.07 Rights of Holders To Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Interest, if any, and interest on the Note, on or after the
respective due dates expressed in the Note (including in connection with an Asset Sale Offer or a Change of Control Offer), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected
without the consent of such Holder. 
 SECTION 6.08 Collection Suit by Trustee. 

If an Event of Default specified in clauses (1) or (2) of Section 6.01 occurs and is continuing, the Trustee is authorized
to recover judgment in its own name and as trustee of an express trust against the Issuer and each Guarantor for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on
overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel. 
 SECTION 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor
upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event 

  
 -88-

 
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 to the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee may participate
as a member of any official committee of creditors appointed in the matters as it deems necessary or advisable. 
 SECTION 6.10
Priorities. 
 If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following
order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07, including
payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any, and interest, ratably, without preference or priority of any kind, according to the
amounts due and payable on the Notes for principal, premium and Additional Interest, if any, and interest, respectively; and 
 Third: to the Issuer or to such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 
 SECTION 6.11 Undertaking for Costs. 
 In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the
party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

 SECTION 7.01 Duties
of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any
Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue

 SECTION 7.05 Notice of Defaults. 
 If a Default or Event of Default occurs
and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of,
premium or Additional Interest, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders
of the Notes.

against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or
expense shall be determined to have been caused by its own negligence or willful misconduct. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or
(9) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

of competent jurisdiction for the appointment of a successor Trustee.

request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

 (f) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to
the Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice
of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for
in Section 7.07. 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.

 ARTICLE 8. 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 SECTION 8.01 Option To Effect Legal Defeasance or
Covenant Defeasance. 
 The Issuer may, at any time, elect to have either Section 8.02 or 8.03 be applied to all
outstanding Notes and all obligations of the Guarantors with respect to the Subsidiary Guarantees upon compliance with the conditions set forth below in this Article 8. 
 SECTION 8.02 Legal Defeasance and Discharge. 
 Upon the Issuer’s
exercise under Section 8.01 of the option applicable to this Section 8.02, the Issuer and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04, be deemed to have been discharged from
their obligations with respect to all outstanding Notes (including the Subsidiary Guarantees) on the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance
means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Subsidiary Guarantees), which shall thereafter be deemed to be “outstanding”
only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Subsidiary Guarantees and this Indenture
(and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: 

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium
and Additional Interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 
 (2) the Issuer’s obligations with respect to such Notes under Sections 2.05, 2.06, 2.07, 2.08 and 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s and the Guarantors’ obligations in connection therewith; and 

(4) this Article 8. 
 Subject to compliance with this Section 8.02, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

 SECTION 8.03 Covenant Defeasance. 
 Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in
Section 8.04, be released from each of their obligations under Sections 4.03, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.14, 4.15 and 4.16 and Section 5.01(a) with respect to the outstanding Notes on and after the date the conditions set
forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall

  
 -95-

 
not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and the Subsidiary Guarantees, the Issuer and the
Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by
reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the
remainder of this Indenture and such Notes and Subsidiary Guarantees shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03 subject to the satisfaction of
the conditions set forth in Section 8.04, Sections 6.01(a)(4) through 6.01(a)(7) and, to the extent relating to a Significant Subsidiary, 6.01(a)(8) and 6.01(a)(9) shall not constitute Events of Default. 

SECTION 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 
 (1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S.
dollars and non-callable Government Securities, in amounts as shall be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, or interest and premium
and Additional Interest, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuer must specify whether the Notes are being defeased to such stated date for
payment or to a particular redemption date; 
 (2) in the case of Legal Defeasance, the Issuer must deliver to
the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or since the Issue Date, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a
result of such Legal Defeasance and shall be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(3) in the case of Covenant Defeasance, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable
to the Trustee confirming that the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and shall be subject to federal income tax on the same amounts, in
the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default
under, any material agreement (including, without limitation, the Credit Agreement) or instrument (other than this Indenture) to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound;

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

  
 -96-

 (6) the Issuer must deliver to the Trustee an Officer’s Certificate and
an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 SECTION 8.05 Deposited Money and Government Securities To Be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 8.05, the “Trustee”) pursuant to Section 8.04 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 (including the Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and Additional Interest,
if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuer
shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 or the principal and interest received in respect thereof
other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 

Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Issuer from time to time upon the
request of the Issuer any money or non-callable Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.04 hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 SECTION 8.06 Repayment to Issuer. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium or Additional Interest, if any, or interest on any Note and
remaining unclaimed for two years after such principal, premium or Additional Interest, if any, or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust;
and the Holder of such Note shall thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof,
shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in The New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such
money then remaining shall be repaid to the Issuer. 

  
 -97-

 SECTION 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and the Guarantors’ obligations under this Indenture and the Notes and the Subsidiary Guarantees shall
be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be;
provided, however, that, if the Issuer makes any payment of principal of, premium or Additional Interest, if any, or interest on any Note following the reinstatement of their obligations, the Issuer shall be subrogated to the rights of
the Holders of such Notes to receive such payment from the cash or Government Securities held by the Trustee or Paying Agent. 

ARTICLE 9. 

AMENDMENT, SUPPLEMENT AND WAIVER 

SECTION 9.01 Without Consent of Holders. 
 (a) Notwithstanding Section 9.02 of this Indenture, the Issuer and the Trustee may amend or supplement this Indenture, the Subsidiary Guarantees or the Notes without the consent of any Holder of a
Note: 
 (1) to cure any ambiguity, defect or inconsistency; 

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

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

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the
TIA; 
 (6) to conform the text of this Indenture, the Subsidiary Guarantees or the Notes to any provision of the

Guarantees or the Notes; 
 (7) to provide for the issuance of Additional Notes in accordance with the
limitations set forth in this Indenture as of the Issue Date; 
 (8) to allow any Guarantor to execute a
supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes, or to secure the Notes; or

to issue the Additional Notes in accordance with the terms herein. 
 (b) Upon the request of the Issuer
accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee shall join with the Issuer in
the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture 

  
 -98-

 
and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that
affects its own rights, duties or immunities under this Indenture or otherwise. Notwithstanding the foregoing, no Opinion of Counsel shall be required in connection with (i) the addition of a Guarantor under this Indenture upon execution and
delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit E hereto, and delivery of an Officer’s Certificate or (ii) the execution and delivery of a
supplemental indenture to this Indenture on the Effective Date, the form of which is attached as Exhibit F hereto, and delivery of an Officer’s Certificate. 
 SECTION 9.02 With Consent of Holders. 
 (a) Except as
provided below in this Section 9.02, the Issuer and the Trustee may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.09 and 4.13 hereof), the Subsidiary Guarantees and the Notes with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes); provided, however, that,
subject to Sections 6.04 and 6.07, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or Additional Interest, if any, or interest on the Notes, except a payment default
resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Subsidiary Guarantees or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then
outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). 
 (b) Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of
evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee shall join with the Issuer in the execution of such amended or supplemental
indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter
into such amended or supplemental indenture. 
 (c) It is not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it is sufficient if such consent approves the substance thereof. 
 (d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07, the Holders of a
majority in aggregate principal amount of the Notes then outstanding, voting as a single class, may waive compliance in a particular instance by the Issuer and the Guarantors with any provision of this Indenture, the Notes, or the Subsidiary
Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 

  
 -99-

 (2) reduce the principal of or change the fixed maturity of any Note or
alter the provisions with respect to the optional redemption of the Notes contained in Section 5 of the Notes (except the notice period contained therein or in Sections 3.01, 3.02 and 3.03); 

(3) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 

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

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

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or interest or premium or Additional Interest, if any, on, the Notes on or after the due date therefor; or 
 (7) make any change in the preceding amendment and waiver provisions. 
 SECTION 9.03 Amendments
regarding Change of Control. 
 Notwithstanding Section 9.01 and 9.02, except as provided in Section 9.01(a)(6),
the defined term “Change of Control” and Section 4.13 hereof maybe waived or modified with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). 
 SECTION 9.04 Compliance with Trust
Indenture Act. 
 Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or
supplemental indenture that complies with the TIA as then in effect. 
 SECTION 9.05 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of
a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of
a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its
terms and thereafter binds every Holder. 
 SECTION 9.06 Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in
exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 

  
 -100-

 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 9.07 Trustee To Sign Amendments, etc. 

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee
shall be provided with and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04, an Officer’s Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
 ARTICLE 10. 

SUBSIDIARY GUARANTEES 
 SECTION
10.01 Guarantee; Right of Payment. 
 (a) Subject to this Article 10, each of the Guarantors hereby,
jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Issuer hereunder or thereunder, that: 
 (1) the principal of, premium and Additional
Interest, if any, and interest on the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other
Obligations of the Issuer to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

(2) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that same shall
be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each
Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) The Guarantors
hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the
Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and
all demands whatsoever and covenant that this Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture or by release in accordance with the provisions of this Indenture.

  
 -101-

 (c) If any Holder or the Trustee is required by any court or otherwise to
return to the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by the Issuer or the Guarantors to the Trustee or such Holder, this
Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 (d)
Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each Guarantor further agrees
that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of this Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and in the event of any declaration of acceleration of such Obligations as provided in Article 6, such
Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the
exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee. 
 SECTION 10.02 [Reserved]. 

SECTION 10.03 Limitation on Guarantor Liability. 
 Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor shall be limited to the maximum amount that shall, after giving effect to such maximum amount and all other contingent and fixed
liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 
 SECTION 10.04 Execution and Delivery of Subsidiary Guarantee. 
 To evidence
its Subsidiary Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit D shall be endorsed by an Officer (or other person serving in a
similar capacity) of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Guarantor by one of its Officers (or other person serving in a similar capacity). 

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee. 
 If an Officer (or other person
serving in a similar capacity) whose signature is on this Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall
be valid nevertheless. 

  
 -102-

 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors. 
 In the event
that the Issuer or any of its Restricted Subsidiaries creates or acquires any Subsidiary after the date of this Indenture, if required by Section 4.16, the Issuer shall cause such Subsidiary to comply with the provisions of Section 4.16
and this Article 10, to the extent applicable. 
 SECTION 10.05 [Reserved]. 

SECTION 10.06 Releases. 
 The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released and discharged upon: 
 (a) (1) any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or otherwise) to a Person that is not (either before or after giving effect to
such transaction) the Issuer or a Restricted Subsidiary (other than a Non-Guarantor Subsidiary), if the sale or other disposition is made in compliance with the applicable provisions of this Indenture; 

(2) any sale or other disposition of all of the Capital Stock of that Guarantor to a Person that is not (either before or
after giving effect to such transaction) the Issuer or a Restricted Subsidiary (other than a Non-Guarantor Subsidiary), after which the applicable Guarantor is no longer a Restricted Subsidiary; 

(3) the proper designation of any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary or a
Non-Guarantor Subsidiary in accordance with the applicable provisions of this Indenture; 
 (4) the release or
discharge of the guarantee by such Guarantor of the Credit Agreement or the guarantee which resulted in the creation of such Guarantee, except a discharge or release by or as a result of payment under such guarantee; or 

(5) the Issuer exercising its legal defeasance option or covenant defeasance option or the Issuer’s obligations under
this Indenture being satisfied and discharged in accordance with Article 8 or Article 11 hereof. 
 (b) such Guarantor
delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in this Indenture relating to such transaction have been complied with. 

If any Guarantor is released from its Subsidiary Guarantee, any of its Subsidiaries that are Guarantors will be released from their
Subsidiary Guarantees, if any. 
 Any Guarantor not released from its obligations under its Subsidiary Guarantee as provided in
this Section 10.06 shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

 ARTICLE 11. 
 SATISFACTION AND DISCHARGE 
 SECTION 11.01 Satisfaction and Discharge. 

This Indenture shall be discharged and shall cease to be of further effect as to all Notes issued hereunder, when: 

(1) either: 
 (a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter
repaid to the Issuer, have been delivered to the Trustee for cancellation; or 
 (b) all Notes that have not been
delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or shall become due and payable within one year or are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer, and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as
trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non- callable Government Securities, in amounts as shall be sufficient, without
consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and Additional Interest, if any, and accrued interest to the date of
maturity or redemption thereof, as the case may be (provided, that if such redemption is made pursuant to Section 3.07 hereof and Section 5(c) of the Notes, (x) the amount of cash in U.S. dollars or U.S. dollar-denominated Government
Securities, or a combination thereof, that the Issuer must irrevocably deposit or cause to be deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit, and (y) the Issuer must irrevocably
deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Applicable Premium as determined on such date); 
 (2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit)
and the deposit shall not result in a breach or violation of, or constitute a default under any other instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than
resulting from any borrowing of funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith); 

(3) the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and 

(4) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money
toward the payment of the Notes at maturity or on the redemption date, as the case may be. 

  
 -104-

 In addition, the Issuer must deliver an Officer’s Certificate and an Opinion of Counsel
to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the
satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to sub-clause of clause of this Section, the provisions of Sections 11.02 and 8.06 shall survive. In addition, nothing in this Section 11.01
shall be deemed to discharge those provisions of Section 7.07, that, by their terms, survive the satisfaction and discharge of this Indenture. 
 SECTION 11.02 Application of Trust Money. 
 Subject to the provisions of
Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such
money need not be segregated from other funds except to the extent required by law. 
 To the extent that and so long as the
Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 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 any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided,
however, that if the Issuer has made any payment of principal of, premium, if any, or interest on any Notes following the reinstatement of their obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive
such payment from the money or Government Securities held by the Trustee or Paying Agent.

 (1) INTEREST. The Issuer promises to pay interest on the principal amount of this Note at
9.000% per annum from April 3, 2012 until maturity and shall pay the Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Issuer shall pay interest and Additional Interest, if any,
semi-annually in arrears on April 1 and October 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes shall accrue from the most
recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that the first Interest Payment Date shall be October 1, 2012. The Issuer shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate equal to the then applicable interest rate on the notes to the extent lawful; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent
lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The
Issuer shall pay interest on the Notes and Additional Interest, if any, to the Persons who are registered Holders at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such Notes are
canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes shall be payable as to principal, interest and premium and Additional
Interest, if any, at the office or agency of the Paying Agent within the City and State of New York, or payment of interest and Additional Interest, if any, may, at the option of the Issuer, be made by check mailed to the Holders at their addresses
set forth in the register of Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal of and interest, premium and Additional Interest, if any, on, all certificated Global
Notes and all other certificated Notes the Holder of which shall have provided wire transfer instructions to the Issuer no less than 30 days prior to the record date. Payment of principal of, premium, if any, and interest and Additional Interest on,
Global Notes registered in the name of or held by DTC or any successor depositary or its nominee will be made by wire transfer of immediately available funds to such depositary or its nominee, as the case may be, as the registered Holder of such
Global Note. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 (3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National Association, the Trustee under the Indenture, shall act as Paying Agent and Registrar. The Issuer may change any Paying Agent or
Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are general unsecured obligations of the Issuer. Subject to the conditions set forth in the Indenture, the Issuer may issue Additional Notes. 

(5) OPTIONAL REDEMPTION. 
 (a) Except as set forth in subparagraph (b) or (c) of this Paragraph 5, on or after April 1, 2015, the Issuer may redeem all or a part of the Notes upon notice as described in
Section 3.02 of the Indenture, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed, to the applicable redemption date,

 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to
April 1, 2015, the Issuer may, upon notice as described in Section 3.02 of the Indenture, on any one or more occasions, redeem up to 40% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of
109.000% of the principal amount, plus accrued and unpaid interest and Additional Interest, if any, to the redemption date, subject to the rights of the Holders on the relevant record date to receive interest on the relevant interest payment date,
with the net cash proceeds of one or more Equity Offerings by the Issuer or a contribution to the equity capital of the Issuer (other than Disqualified Stock) from the net proceeds of one or more Equity Offerings by Holdings or any other direct or
indirect parent of the Issuer (in each case, other than Excluded Contributions); provided that: 
 (1) at
least 50% of the aggregate principal amount of Notes originally issued under the Indenture (excluding Notes held by the Issuer and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 

(2) the redemption occurs within 90 days of the date of the closing of such Equity Offering or equity contribution.

 (c) Before April 1, 2015, the Issuer may also redeem all or any portion of the Notes upon notice as described in
Section 3.02 of the Indenture, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued and unpaid interest thereon, if any, to, the date of redemption (a “Make-Whole Redemption

 (8) REPURCHASE AT THE OPTION OF HOLDER. 

(a) If there is a Change of Control after the Effective Date, each Holder shall have the right to require the Issuer to make an offer (a
“Change of Control Offer”) to repurchase all or any part (a minimum amount of $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased, if any, to the date of purchase, subject to the rights of the Holders on the relevant record date to receive interest due on the relevant Interest
Payment Date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Issuer shall mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

 (b) If the Issuer or a Restricted Subsidiary consummates any Asset Sales, within 10 Business Days of each date on which the
aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuer shall commence an Asset Sale Offer to all Holders and if the Issuer elects (or is required by the terms of such other Pari Passu Indebtedness) all holders of such Pari Passu
Indebtedness to purchase the maximum principal amount of Notes and other Pari Passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and
unpaid interest and Additional Interest, if any, to the Purchase Date in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and other Pari Passu Indebtedness tendered pursuant to an Asset Sale
Offer is less than the Excess Proceeds, the Issuer may use the remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other Pari Passu Indebtedness surrendered by holders
thereof exceeds the amount of Excess Proceeds, the Trustee or the Issuer, as applicable, shall select the Notes and other Pari Passu Indebtedness to be purchased on a pro rata basis. Holders to whom an Asset Sale Offer is addressed shall receive an
Asset Sale Offer from the Issuer prior to the related Purchase Date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes. 

(9) NOTICE OF REDEMPTION. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption
date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a
satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after the
redemption date interest and Additional Interest will cease to accrue on Notes or portions thereof called for redemption. 

(10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except
for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and
the corresponding Interest Payment Date.

a purchase of, or tender offer or exchange offer for, Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture, the Subsidiary Guarantees or the Notes may be waived with the consent of the Holders of a

Indenture, the Subsidiary Guarantees or the Notes to any provision of the “Description of Notes” section of the Offering Memorandum to the extent that such provision in that “Description of Notes” was intended to be a verbatim
recitation of a provision of the Indenture, the Subsidiary Guarantees or the Notes, (vii) to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture as of the Issue Date, (viii) to allow
any Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes or to secure the Notes, or (ix) to issue additional notes in accordance with the terms of the Indenture.

Additional Interest, if any, with respect to, the Notes; (ii) default in payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on the Notes; (iii) failure by the Issuer to comply with
Section 5.01 of the Indenture; (iv) failure by the Issuer or any of its Restricted Subsidiaries for 60 days after notice to the Issuer by the Trustee or the Holders of at least 25% in aggregate principal amount of Notes then outstanding
voting as a single class to comply with any of the other agreements in the Indenture; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Issuer or any of its Significant Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its Significant Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Effective
Date, if that default: (A) is caused by a failure to pay principal at the final Stated Maturity of such Indebtedness (a “Payment Default”) or (B) results in the acceleration of such Indebtedness prior to its express maturity,
and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $35.0 million
or more; (vi) certain final judgments and decrees for the payment of money that remain undischarged for a period of 60 days after such judgment or decree has become final and nonappealable without being paid, discharged, waived or stayed;
(vii) except as permitted by the Indenture, any Subsidiary Guarantee of any Significant Subsidiary is declared to be unenforceable or invalid by any final and nonappealable judgment or decree or ceases for any reason to be in full force and
effect, or any Guarantor that is a Significant Subsidiary or any Person acting on behalf of any Guarantor that is a Significant Subsidiary denies or disaffirms its obligations in writing under its Subsidiary Guarantee and such Default continues for
10 days after receipt of the notice specified in the Indenture and (viii) certain events of bankruptcy or insolvency with respect to the Issuer or any of the Issuer’s Restricted Subsidiaries that is a Significant Subsidiary. In the event
of 

  
 A1-6

 
any Event of Default specified in clause (v) above, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the
Notes) shall be annulled, waived and rescinded, automatically and without action by the Trustee or the Holders, if within 20 days after such Event of Default arose (1) the Indebtedness or Guarantee that is the basis for such Event of Default
has been discharged; (2) holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default; or (3) the default that is the basis for such Event of Default has been cured.
Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes shall become due and payable without further action or notice. If any other Event of Default occurs and
is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided
in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest or Additional Interest) if a committee of its Responsible Officer determines in good faith that withholding notice is in
their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of interest on, premium, if any, Additional Interest, if any, or the principal of any of the Notes held by a non-consenting Holder (including in connection with an offer to
purchase). 
 (14) TRUSTEE DEALINGS WITH 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 its Affiliates, as if it were not the Trustee. 
 (15) NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator, stockholder, member, partner or other holder of Equity Interests of the Issuer or any Guarantor, as such, shall have
any liability for any obligations of the Issuer or the Guarantors under the Notes, this Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a
Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws. 

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

(18) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND RESTRICTED DEFINITIVE NOTES. In addition to the rights provided
to Holders under the Indenture, Holders of Restricted Global Notes and Restricted Definitive Notes shall have all the rights set forth in the Registration Rights Agreement.

thereof) of that Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased, if any, to the date of purchase, subject to

Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 

  
 A2-6

 (b) If the Issuer or a Restricted Subsidiary consummates any Asset Sales, within 10 Business
Days of each date on which the aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuer shall commence an Asset Sale Offer to all Holders and if the Issuer elects (or is required by the terms of such other Pari Passu Indebtedness) all
holders of such Pari Passu Indebtedness to purchase the maximum principal amount of Notes and other Pari Passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount
thereof plus accrued and unpaid interest and Additional Interest, if any, to the Purchase Date in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and other Pari Passu Indebtedness tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer may use the remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other Pari Passu
Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee or the Issuer, as applicable, shall select the Notes and other Pari Passu Indebtedness to be purchased on a pro rata basis. Holders to whom an Asset Sale
Offer is addressed shall receive an Asset Sale Offer from the Issuer prior to the related Purchase Date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes
or a satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after
the redemption date interest and Additional Interest will cease to accrue on Notes or portions thereof called for redemption. 

(10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except
for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and
the corresponding Interest Payment Date. 
 (11) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as
its owner for all purposes. 
 (12) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the
Subsidiary Guarantees or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes, including without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for, Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture, the Subsidiary Guarantees or the Notes may be waived with the consent of the Holders of a

to effect or maintain the qualification of the Indenture under the TIA, (vi) to conform the text of the Indenture, the Subsidiary Guarantees or the Notes to any provision of the “Description of Notes” section of the Offering
Memorandum to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of the Indenture, the Subsidiary Guarantees or the Notes, (vii) to provide for the issuance of
Additional Notes in accordance with the limitations set forth in the Indenture as of the Issue Date, (viii) to allow any Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes or to secure the
Notes, or (ix) to issue additional notes in accordance with the terms of the Indenture.

the Issuer by the Trustee or the Holders of at least 25% in aggregate principal amount of Notes then outstanding voting as a single class to comply with any of the other agreements in the Indenture; (v) default under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Issuer or any of its Significant Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its
Significant Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Effective Date, if that default: (A) is caused by a failure to pay principal at the final Stated Maturity of such Indebtedness (a
“Payment Default”) or (B) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $35.0 million or more; (vi) certain final judgments and decrees for the payment of money that remain undischarged for a period of 60 days
after such judgment or decree has become final and nonappealable without being paid, discharged, waived or stayed; (vii) except as permitted by the Indenture, any Subsidiary Guarantee of any Significant Subsidiary is declared to be
unenforceable or invalid by any final and nonappealable judgment or decree or ceases for any reason to be in full force and effect, or any Guarantor that is a Significant Subsidiary or any Person acting on behalf of any Guarantor that is a
Significant Subsidiary denies or disaffirms its obligations in writing under its Subsidiary Guarantee and such Default continues for 10 days after receipt of the notice specified in the Indenture and (viii) certain events of bankruptcy or
insolvency with respect to the Issuer or any of the Issuer’s Restricted Subsidiaries that is a Significant Subsidiary. In the event of any Event of Default specified in clause (v) above, such Event of Default and all consequences thereof
(excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without action by the Trustee or the Holders, if within 20 days after such Event of Default
arose (1) the Indebtedness or Guarantee that is the basis for such Event of Default has been discharged; (2) holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of
Default; or (3) the default that is the basis for such Event of Default has been cured. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes shall
become due and payable without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be
due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in
its exercise of any trust or power. The Trustee may 

  
 A2-8

 
withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest or Additional Interest)
if a committee of its Responsible Officer determines in good faith that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the
Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, premium, if any, Additional Interest, if any, or the
principal of any of the Notes held by a non-consenting Holder (including in connection with an offer to purchase.

            , 200            , among
            (the “Guaranteeing Subsidiary”), a subsidiary of [USPI Finance Corp.][United Surgical Partners International, Inc.], a Delaware corporation, the Issuer and U.S.
Bank National Association, as trustee under the Indenture referred to below (the “Trustee”). 
 WITNESSETH 

WHEREAS, the Issuer has heretofore executed and delivered to the Trustee an indenture (as amended, supplemented or otherwise modified,
the “Indenture”), dated as of April 3, 2012, providing for the issuance of 9.000% Senior Notes due 2020 (the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary
shall unconditionally guarantee all of the Issuer’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Subsidiary Guarantee”); and 

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 
 2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Subsidiary Guarantee and in this
Indenture including but not limited to Article 10 thereof.
