 2.0 Project Overview 
 2.1 Scope of the Agreement; Service Contract.
Nature of Services; Scope of Agreement. As a “master” form of contract, this Agreement allows the parties to contract for multiple Projects through the issuance of multiple Service Contract(s) without having to re-negotiate the basic
terms and conditions contained herein. This Agreement covers the provision of services by PII required in connection with any Project (the “Services”), and represents a vehicle by which Customer can efficiently contract with PII for a
broad range of services. 
 2.2 Service Contract. The specific details of each Project under this Agreement shall be
separately negotiated and set forth in a service contract, each to be agreed upon in writing by PII and Horizon (each a “ Service Contract”) Each Service Contract will include, as appropriate, the scope of

  

 2 

 
work, time line, and budget and payment schedule. Each Service Contract shall be subject to all of the terms and conditions of this Agreement, in addition to the specific details set forth in the
Service Contract. To the extent any terms or provisions of a Service Contract conflict with the terms and provisions of this Agreement, the terms and provisions of this Agreement shall control. All Service Contracts and other exhibits hereto shall
he deemed to be incorporated herein by reference. 
 2.3 Nature of Services. 

(a) PII shall perform the Projects described in each Service Contract and shall deliver to Customer the deliverables, including any
pharmaceutical product (“Product”), described in each Service Contract (the “Deliverables”) on or before the “Delivery Time” described in each Service Contract, subject to Sections 2.3(b) and 12 below. PII acknowledges

connection with each Project in conformity with the requirements for such Services as set forth in the applicable Service Contract (the “Requirements”) and this Agreement. The parties acknowledge that PII may perform the Projects using its
affiliates, provided that such performance is in accordance with this Agreement, and PII remains responsible to Customer for the performance of such Project(s). 
 (b) The parties acknowledge that both parties will require certain information and reasonable cooperation from each other in order to properly perform each Project, and that each party will establish
mutually acceptable review periods for the development and completion of each Service Contract, prior to the initiation of work for that Service Contract. Once the Service Contract is signed and the initiation fee is paid, as applicable under such
Service Contract, PII will be responsible and liable for meeting the Delivery Time and shall use its commercially reasonable efforts to deliver all Deliverables on or before the applicable Delivery Time, subject to Section 12 below and delays
in its performance caused by Customer’s failure to provide Customer Materials, required information and reasonable cooperation to PII in a timely manner. In the event PII will be unable to meet the Delivery Date, PII will promptly notify

the Product meets the Specifications for the Product set forth in the applicable Service Contract (a “COA”). Customer and PII agree that the review period and the acceptance or rejection of Product cannot commence until the COA, and Batch
Records are received for each batch of Product (including all the batch 
  

 ***Confidential Treatment Requested

[...***...] following delivery to Customer of the Product, COA and the Batch Record in accordance with Section 2.8.1, Customer shall have the right to give PII notice of rejection of any Product that, in whole or part, fails to conform to
the Specifications. Upon receipt of a notice of rejection from Customer, PII shall conduct an internal Investigation. Customer shall at all times supply PII with any evidence it has that relates to whether any Product delivered to Customer by PII is
non-conforming with the Specifications. Failure by Customer to give timely notice of rejection shall constitute acceptance by it of the shipment to which the notice of rejection would have otherwise applied; provided, however, that in the case of
Product having Latent Defect(s), Customer may reject such Product by giving written notice to PII of Customer’s rejection of such Product within [...***...] after discovery of such Latent Defect(s). In the event of any disagreement
between PII and Customer relating to non-conformance under this Section 2.8, the parties shall use good faith efforts to reach an amicable resolution of such disagreement. In the event that resolution cannot be reached, a mutually agreed upon,
neutral, independent third party laboratory shall be brought in to resolve the disagreement upon the request of either party. The results of the independent laboratory shall be binding on the parties and non-appealable, and the cost of such
independent laboratory shall be borne by the party hereunder determined by the independent laboratory to be the non-prevailing party in such disagreement. Any Product properly rejected pursuant to this Section 2.8.2 shall be returned by
Customer to PII at PII’s expense and shall be replaced by PII at no extra charge to Customer, subject to Customer’s provision to PII of Customer Materials (which may be at PII’s cost, as provided herein), including any API; and in the
event PII cannot replace such returned Product, it shall refund to Customer the amount paid, including any freight, insurance or other direct costs actually incurred by Customer. Customer agrees that in the event the replacement cost of the API used
in any Service Contract exceeds [...***...], the amount of the replacement cost shall be conspicuously set forth in the Service Contract. 
 2.8.3. Notwithstanding anything to the contrary contained herein, PII shall not be responsible for the stability of any Product if PII has performed its Services in accordance with the Requirements and
the terms and conditions of this Agreement. Unless PII delivers Product to Customer with a COA and Customer properly rejects any Product in accordance with the provisions of Section 2.8.2 above, as long as, with respect to any batch of
non-conforming Product, PII has performed such Services in accordance with the Requirements and the terms and conditions of this Agreement: (a) PII shall be entitled to payment for its Services actually performed under any Service Contract, and
(b) PII shall not be responsible for the cost of replacement API required for PII’s replacement of defective Product. 

2.9 Commercial Supply. The parties hereby agree that, upon written request by Customer to PII, the parties shall negotiate in good
faith and enter into a supply agreement in form mutually acceptable to the parties relating to supply by PII to Customer of Customer’s requirements of Product for Customer’s development and commercialization activities. The parties agree

 12. Force Majeure Notwithstanding anything to the contrary contained herein, neither party
shall be liable for non-performance or late performance of any of its obligations under this Agreement (other than obligations to pay money) to the extent such non-performance or late performance is due to reasons of strike, riots, war, act of God,
invasion, acts of terrorism, fire, explosion floods, interruption of or delay in transportation, shortage or failure in the supply of Customer Materials, acts of government or governmental agencies or instrumentalities and any other contingencies
beyond the party’s reasonable control.

whether ambiguous, unclear or otherwise, in favor of or against any party based on the party that drafted such language. 
 14.7
Counterparts. This Agreement may be executed in any number of counterparts, and each such counterpart shall be deemed to be an original instrument, but all such counterparts together shall constitute but one agreement. 

14.8 Survival. No termination or expiration of this Agreement shall relieve the parties hereto of any obligation hereunder which
by its terms is intended to or may survive the termination or expiration of this Agreement, including, without limitation, Sections 2.4, 2.5, 2.7, 2.8, 2.9, 4.5, 9.3 and 9.4, and Articles 5, 6, 7, 10, 11, 12, 13 and 14, which will survive expiration

 14.9 Relationship Between Parties. PII’s relationship to Customer shall be that
of an independent contractor. No persons engaged by PII shall be considered under the provisions of this Agreement or otherwise as an employee of Customer. Nothing contained in this Agreement shall create or imply the creation of a partnership
between Customer and PII and neither party shall have any authority (actual or apparent) to bind the other.

copy (as the case may be) is sent by next day express delivery service or facsimile. All communication hereunder, and all written Project Materials and Deliverables, shall be in the English language.

Coverage Ratio” means as of any date of determination, with respect to any Person, the ratio of (x) the aggregate amount of Consolidated EBITDA of such Person for the period of the most recent four consecutive fiscal quarters ending
prior to the date of such determination for which financial statements are in existence to (y) Consolidated Fixed Charges for such four fiscal quarters; provided, however, that: 

(1) if the Company or any Restricted Subsidiary: 

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of
determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDA and Consolidated Fixed Charges for such period will be calculated after giving effect on a
pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of Indebtedness under any revolving credit facility drawn for working capital
purposes in the ordinary course of business outstanding on the date of such calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was
outstanding or (ii) if such facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such facility to the date of such calculation) and the
discharge of any other Indebtedness repaid, repurchased, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period; or 

(b) has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period that is
no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case other than Indebtedness Incurred under any revolving
credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated EBITDA and Consolidated Fixed Charges for such period will be calculated after giving effect on a pro forma basis to
such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period; 
 (2) if since the beginning of such period the Company or any Restricted Subsidiary will have made any asset sale or other disposition or if the transaction giving rise to the need to calculate the
Consolidated Coverage Ratio is such an asset sale or other disposition: 
 (a) the Consolidated EBITDA for such
period will be reduced by an amount equal to the Consolidated EBITDA (if positive) directly attributable to the assets which are the subject of such asset sale or other disposition for such period or increased by an amount equal to the Consolidated
EBITDA (if negative) directly attributable thereto for such period; and 

  
 -7-

  
 (b)
Consolidated Fixed Charges for such period will be reduced by an amount equal to the Consolidated Fixed Charges directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise
discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such asset sale or other disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Fixed Charges
for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale); 

(3) if since the beginning of such period the Company or any Restricted Subsidiary (by merger, consolidation, acquisition
of Capital Stock or otherwise) will have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged or consolidated with or into the Company) or an acquisition of assets, including any
acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of
business, Consolidated EBITDA and Consolidated Fixed Charges for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first
day of such period; and 
 (4) if since the beginning of such period any Person (that subsequently became a
Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) will have Incurred any Indebtedness or discharged any Indebtedness or made any asset sale or other disposition or any
Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated EBITDA and Consolidated Fixed Charges for
such period will be calculated after giving pro forma effect thereto as if such transaction occurred on the first day of such period. 
 For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations (including pro forma expense and cost
reductions calculated on a basis consistent with Regulation S-X under the Securities Act) will be determined in good faith by a responsible financial or accounting officer of the Company; provided that such pro forma calculations may
include operating expense reductions for such period resulting from the transaction which is being given pro forma effect that have been realized or for which the steps necessary for realization have been taken or are reasonably expected to
be taken within one year following any such transaction (which operating expense reductions are reasonably expected to be sustainable). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest
expense on such Indebtedness will be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such
Interest Rate Agreement has a remaining term in excess of 12 months). If any Indebtedness that 

  
 -8-

 
is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company. 

“Consolidated Debt Expense” means, for any period, without duplication, the total debt expense of the Company and its
consolidated Restricted Subsidiaries, computed on a consolidated basis, whether paid or accrued, and included in debt expense as set forth on the statement of operations of the Company, plus, to the extent not included in such debt expense
and without duplication: 
 (1) interest expense attributable to Capitalized Lease Obligations and the interest
portion of rent expense associated with Attributable Indebtedness in respect of the relevant lease giving rise thereto, determined as if such lease were a capitalized lease in accordance with GAAP and the interest component of any deferred payment
obligations; 
 (2) amortization of debt discount and debt issuance cost (provided that any amortization
of bond premium will be credited to reduce Consolidated Debt Expense unless, pursuant to GAAP, such amortization of bond premium has otherwise reduced Consolidated Debt Expense); 

(3) non-cash interest expense; 
 (4) commissions, discounts and other fees and charges owed with respect to letters of credit and bankers’ acceptance financing; 

(5) interest expense on Indebtedness of another Person that is Guaranteed by such Person or one of its Restricted
Subsidiaries or secured by a Lien on assets of such Person or one of its Restricted Subsidiaries; 
 (6) cash
costs associated with Hedging Obligations (including amortization of fees but excluding mark-to-market charges or adjustments); provided, however, that if Hedging Obligations result in net benefits rather than costs, such benefits
shall be credited to reduce Consolidated Debt Expense unless, pursuant to GAAP, such net benefits are otherwise reflected in Consolidated Net Income; 
 (7) the consolidated interest expense of such Person and its Restricted Subsidiaries that was capitalized during such period; and 

(8) the cash contributions to any employee stock ownership plan or stock option plan to the extent such contributions are
used by such plan or trust to pay interest or fees to any Person (other than the Company and its Restricted Subsidiaries) in connection with Indebtedness incurred by such plan or trust. 

For the purpose of calculating the Consolidated Coverage Ratio in connection with the Incurrence of any Indebtedness described in the
final paragraph of the definition of “Indebtedness,” the calculation of Consolidated Debt Expense shall include all interest expense (including any amounts described in clauses (1) through (8) above) relating to any Indebtedness
of 

  
 -9-

 
the Company or any Restricted Subsidiary described in the final paragraph of the definition of “Indebtedness.” 
 For purposes of the foregoing, total debt expense will be determined (i) after giving effect to any net payments made or received by the Company and its Subsidiaries with respect to Interest Rate
Agreements, (ii) exclusive of amounts classified as other comprehensive income in the balance sheet of the Company and (iii) exclusive of the write-off of deferred financing costs. Notwithstanding anything to the contrary contained herein,
commissions, discounts, yield and other fees and charges Incurred in connection with any transaction pursuant to which the Company or its Restricted Subsidiaries may sell, convey or otherwise transfer or grant a security interest in any accounts
receivable or related assets shall be included in Consolidated Debt Expense. 
 “Consolidated EBITDA” for any
period means, without duplication, the Consolidated Net Income for such period, plus the following, to the extent deducted or taken into account in calculating such Consolidated Net Income: 

(1) Consolidated Fixed Charges; 
 (2) Consolidated Income Taxes; 
 (3) consolidated expenses for
valuation adjustments or impairment charges; 
 (4) consolidated depreciation or amortization expense;

 (5) expenses and charges relating to non-controlling interests and equity income in consolidated Subsidiaries;
and 
 (6) other non-cash charges reducing Consolidated Net Income (excluding any such non-cash charge to the
extent it represents an accrual of or reserve for cash charges in any future period or amortization of a prepaid cash expense that was paid in a prior period not included in the calculation). 

Notwithstanding the preceding sentence, clauses (2) through (6) relating to amounts of a Restricted Subsidiary of a Person will
be added to Consolidated Net Income to compute Consolidated EBITDA of such Person only to the extent (and in the same proportion) that the net income (loss) of such Restricted Subsidiary was included in calculating the Consolidated Net Income of
such Person and, to the extent the amounts set forth in clauses (2) through (6) are in excess of those necessary to offset a net loss of such Restricted Subsidiary or if such Restricted Subsidiary has net income for such period included in
Consolidated Net Income, only if a corresponding amount would be permitted at the date of determination to be dividended to the Company by such Restricted Subsidiary without prior approval (that has not been obtained), pursuant to the terms of its
charter and all agreements, instruments, judgments, decrees, orders, statutes, rules and governmental regulations applicable to that Restricted Subsidiary or its stockholders.

fraction, the numerator of which is one and the denominator of which is one minus the then current combined federal, state, provincial and local statutory tax rate of such Person, expressed as a decimal, in each case, on a consolidated basis and in
accordance with GAAP. 
 “Consolidated Income Taxes” means, with respect to the Company and its consolidated
Restricted Subsidiaries for any period, on a consolidated basis and without duplication, taxes imposed upon the Company or other payments required to be made by the Company by any governmental authority which taxes or other payments are calculated
by reference to the income or profits of the Company or the Company and its consolidated Restricted Subsidiaries (to the extent such income or profits were included in computing Consolidated Net Income for such period), other than income taxes
attributable to extraordinary, unusual or nonrecurring gains or losses or taxes attributable to sales or dispositions outside the ordinary course of business. 
 “Consolidated Net Income” means, for any period, the net income (loss) of the Company and its consolidated Restricted Subsidiaries determined on a consolidated basis in accordance with
GAAP; provided, however, that there will not be included in such Consolidated Net Income: 
 (1)
any net income (loss) of any Person if such Person is not a Restricted Subsidiary, except that: 
 (a) subject to
the limitations contained in clauses (3) through (9) below, the Company’s equity in the net income of any such Person for such period will be included in such Consolidated Net Income up to the aggregate amount of cash actually
distributed by such Person during such period to the Company or a Restricted Subsidiary as a dividend or other distribution (subject, in the case of a dividend or other distribution to a Restricted Subsidiary, to the limitations contained in clause
(2) below); and 
 (b) the Company’s equity in a net loss of any such Person for such period will be
included in determining such Consolidated Net Income;

Subsidiary if such Subsidiary is subject to restrictions, directly or indirectly, by operation of the terms of its charter, any contract or agreement, operation of law or otherwise, on the payment of dividends or the making of distributions by such
Restricted Subsidiary, directly or indirectly, to the Company, except that: 

  
 -11-

  
 (a)
subject to the limitations contained in clauses (3) through (9) below, the Company’s equity in the net income of any such Restricted Subsidiary for such period will be included in such Consolidated Net Income up to the aggregate
amount of cash that could have been distributed by such Restricted Subsidiary (excluding the effect of restrictions relating to the Senior Credit Facilities permitted pursuant to clauses (i) and (iii) of the second paragraph of
Section 4.14) during such period to the Company or another Restricted Subsidiary as a dividend (subject, in the case of a dividend to another Restricted Subsidiary, to the limitation contained in this clause); and 

(b) for the avoidance of doubt, the Company’s equity in a net loss of any such Restricted Subsidiary for such period
will be included in determining such Consolidated Net Income; 
 (3) any gain (loss) realized upon the sale or
other disposition of any property, plant or equipment of the Company or its consolidated Restricted Subsidiaries (including pursuant to any Sale/Leaseback Transaction) which is not sold or otherwise disposed of in the ordinary course of business and
any gain (loss) realized upon the sale or other disposition of any Capital Stock of any Person; 
 (4) any gain
or loss arising from the early extinguishment of any Indebtedness in connection with the Transactions, including the amortization or write-off of debt issuance costs or debt discount in connection with the Transactions; 

(5) any non-cash compensation charges arising from the grant of, issuance, vesting or repricing of stock, stock options or
other equity-based awards or any amendment, modification, substitution or change of any such stock, stock options or other equity-based awards;

(9) gains and losses due solely to fluctuations in currency values. 

For purposes of this definition of “Consolidated Net Income,” “nonrecurring” means any gain or loss as of any
date that is not reasonably likely to recur within the two years following such date; provided that if there was a gain or loss similar to such gain or loss within the two years preceding such date, such gain or loss shall not be deemed
nonrecurring. 
 “Consolidated Total Leverage Ratio” means, as of any date of determination, with respect to
the Company and its consolidated Restricted Subsidiaries, the ratio of (x) the 

  
 -12-

 
aggregate amount of all Indebtedness of the Company and its consolidated Restricted Subsidiaries (“Consolidated Total Indebtedness”) as of the last day of the period of the most
recent four consecutive fiscal quarters ending prior to the date of determination for which financial statements are in existence to (y) the aggregate amount of Consolidated EBITDA of the Company and its consolidated Restricted Subsidiaries for
such period, all calculated on a consolidated basis in accordance with GAAP. For purposes of calculating the Consolidated Total Leverage Ratio, Consolidated EBITDA shall, if necessary, be calculated on a pro forma basis in a manner consistent
with the proviso to the first sentence of the definition of “Consolidated Coverage Ratio”; and Consolidated Total Indebtedness shall, if necessary, be calculated on a pro forma basis as follows:

 (6) “herein,” “hereof” and other words of similar
import refer to this Indenture as a whole and not to any particular Article, Section or other subdivision; and 

(7) the words “including,” “includes” and similar words shall be deemed to be followed by
“without limitation.” 
 ARTICLE TWO 
 THE NOTES 
 SECTION 2.01. Form and Dating. 

The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The
Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall approve the form of the Notes and any notation, legend or endorsement on them. Each Note shall be dated the date of its
authentication. Each Note shall have an executed Note Guarantee from each of the Subsidiary Guarantors endorsed thereon substantially in the form of Exhibit C. 
 The terms and provisions contained in the Notes and the Note Guarantees shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors
and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 
 The Notes shall be issued initially in the form of one or more Global Notes, substantially in the form set forth in Exhibit A, deposited with the Trustee, as custodian for the Depository, duly
executed by the Company (and having an executed Note Guarantee from each of the Guarantors endorsed thereon) and authenticated by the Trustee as hereinafter provided and shall bear the legends set forth in Exhibit B. The aggregate
principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depository, as hereinafter provided. 

Notes may be issued in the form of permanent certificated Notes in registered form in substantially the form set forth in
Exhibit A (the “Physical Notes”) in exchange for interests in Global Notes only in the circumstances and manner set forth in Section 2.15. 
 SECTION 2.02. Execution and Authentication. 
 Two Officers of the Company
(who shall have been duly authorized by all requisite corporate actions) shall sign the Notes for the Company by manual or facsimile signature. 

  
 -38-

  
 If an Officer whose
signature is on a Note or Note Guarantee, as the case may be, was an Officer at the time of such execution but no longer holds that office at the time the Trustee authenticates the Note, the Note or Note Guarantee, as the case may be, shall
nevertheless be valid. 
 A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate
of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee shall authenticate Notes for original issue on the Issue Date in the aggregate principal amount of $775,000,000 upon a written order of the Company in the form of an Officers’
Certificate. In addition, the Trustee shall authenticate Notes (“Additional Notes”) thereafter in unlimited amount (so long as not otherwise prohibited by the terms of this Indenture, including without limitation, Section 4.10)
for original issue upon a written order of the Company in the form of an Officers’ Certificate. Each such Officers’ Certificate shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated.

 The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Notes. Unless otherwise
provided in the appointment, 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 the Company and Affiliates of the Company. 
 The Notes shall be issuable only in registered
form without coupons in denominations of $1,000 and integral multiples thereof. 
 SECTION 2.03. Registrar and Paying Agent. 

The Company shall maintain an office or agency in the Borough of Manhattan, The City of New York, where (a) Notes may be presented
or surrendered for registration of transfer or for exchange (“Registrar”), (b) Notes may be presented or surrendered for payment (“Paying Agent”) and (c) notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such
purposes. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Restricted Subsidiaries may act as its own Registrar or Paying Agent provided compliance with the proviso of the previous
sentence. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company, upon notice to the Trustee, may have one or more co-Registrars and one or more additional paying agents reasonably acceptable to the Trustee.
The term “Paying Agent” includes any additional paying agent. The Company initially appoints the Trustee as Registrar and Paying Agent until such time as the Trustee has resigned or a successor has been appointed. 

  
 -39-

  
 The Company shall
enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee, in advance, of the name and
address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such. 
 SECTION 2.04.
Paying Agent To Hold Assets in Trust. 
 The Company shall require each Paying Agent other than the Trustee to agree in
writing that each Paying Agent shall hold in trust for the benefit of Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, or interest on, the Notes (whether such assets have been distributed to it by the
Company or any other obligor on the Notes), and shall notify the Trustee of any Default by the Company (or any other obligor on the Notes) in making any such payment. The Company at any time may require a Paying Agent to distribute all assets held
by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the
Trustee and to account for any assets distributed. Upon distribution to the Trustee of all assets that shall have been delivered by the Company to the Paying Agent, the Paying Agent shall have no further liability for such assets. 

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 Holders. If the Trustee is not the Registrar, the Company
shall furnish to the Trustee at least two (2) Business Days prior to each Interest Payment Date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the
names and addresses of Holders, which list may be conclusively relied upon by the Trustee. 
 SECTION 2.06. Transfer and Exchange.

 Subject to Section 2.15, when Notes are presented to the Registrar or a co-Registrar with a request to register the
transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the Registrar or co-Registrar shall register the transfer or make the exchange as requested if its requirements for such
transaction are met; provided, however, that the Notes surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar or
co-Registrar, duly executed by the Holder thereof or his or her attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Notes at the Registrar’s or
co-Registrar’s request. No service charge shall be imposed upon the Company, the Trustee or any Agent for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith. 
 The Registrar or co-Registrar shall not be required to register the
transfer of or exchange of any Note (i) during a period beginning at the opening of business 15 days before the 

  
 -40-

 
mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing, (ii) selected for redemption in whole or in part pursuant to Article Three, except
the unredeemed portion of any Note being redeemed in part, and (iii) during a Change of Control Offer or an Asset Disposition Offer if such Note is validly tendered pursuant to such Change of Control Offer or Asset Disposition Offer and not
validly withdrawn. 
 Any Holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest,
agree that transfers of beneficial interests in such Global Notes may be effected only through a book-entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in the Note shall be required
to be reflected in a book-entry system. 
 SECTION 2.07. Replacement Notes. 

If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the Trustee’s requirements are met. Such Holder must provide an indemnity bond or other indemnity, sufficient in the judgment of both the Company and the
Trustee, to protect the Company, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note pursuant to this
Section 2.07, including reasonable fees and expenses of counsel and of the Trustee. 
 Every replacement Note is an
additional obligation of the Company and every replacement Note Guarantee shall constitute an additional obligation of the Guarantor thereof. 

SECTION 2.08. Outstanding Notes. 
 Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section as not
outstanding. A Note does not cease to be outstanding because the Company, the Guarantors or any of their respective Affiliates holds the Note (subject to the provisions of Section 2.09). 

If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be
outstanding unless a Responsible Officer of the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof
pursuant to Section 2.07. If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a Redemption Date, the Maturity Date, a Change of Control Payment Date,
an Asset Sale Payment Date or any other date payment on the Notes is due the Trustee or Paying Agent (other than the Company or an Affiliate thereof) holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal and
interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. 

  
 -41-

  
 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 Company or any of its Affiliates shall be disregarded, except that, for the purposes of determining whether the Trustee shall be protected in conclusively relying on any such direction, waiver or consent, only Notes that
a Responsible Officer of the Trustee actually knows are so owned shall be disregarded. 
 SECTION 2.10. Temporary Notes. 

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

SECTION 2.11. Cancellation. 
 The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment.
The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent (other than the Company or a Subsidiary), and no one else, shall cancel and, at the written direction of the Company, shall dispose of all Notes surrendered for
transfer, exchange, payment or cancellation in accordance with its customary procedures. Subject to Section 2.07, the Company may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Company
or any Guarantor 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 Company defaults in a payment of interest on the Notes, it shall, unless the Trustee fixes another record date pursuant to Section 6.10, pay the defaulted interest, plus (to the extent lawful)
any interest payable on the defaulted interest pursuant to this Indenture, in any lawful manner. The Company may pay the defaulted interest to the persons who are Holders on a subsequent special record date, which date shall be the fifteenth day
next preceding the date fixed by the Company for the payment of defaulted interest. At least 15 days before any such subsequent special record date, the Company shall mail to each Holder, with a copy to the Trustee, a notice that states the
subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. 

  
 -42-

  
 SECTION 2.13. CUSIP Number.

 The Company in issuing the Notes may use a “CUSIP” number, and if so, the Trustee shall use the CUSIP number in
notices of redemption, repurchase or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or
on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee in writing of any change in the CUSIP numbers. 

SECTION 2.14. Deposit of Moneys. 
 Prior to 11:00 a.m. New York City time on each Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, the Company shall have deposited
with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, as the case
may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date or Asset Disposition Purchase Date, as the case may be.

 SECTION 2.15. Book-Entry Provisions for Global Notes. 
 (a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and
(iii) bear legends as set forth in Exhibit B. 
 Members of, or participants in, the Depository
(“Participants”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Note, and the Depository may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company
or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and Participants, the operation of customary practices governing the exercise of the rights
of a Holder or beneficial owner of any Note. 
 (b) Transfers of Global Notes shall be limited to transfers in whole, but not in
part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be exchanged for Physical Notes only as follows: Physical Notes shall be transferred to all beneficial owners in exchange
for their beneficial interests in Global Notes if (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for any Global Note and a successor Depository is not appointed by the Company, with a copy to
the Trustee, within 90 days of such notice or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the Depository to issue Physical Notes. 

  
 -43-

  
 (c) In connection with
the transfer of a Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.15, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and (i) the Company shall execute, (ii) the
Guarantors shall execute notations of Note Guarantees on and (iii) the Trustee shall upon written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial
interest in such Global Note, an equal aggregate principal amount of Physical Notes of authorized denominations. 
 (d) The
Holder of any Global Note may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Notes.

 ARTICLE THREE 
 REDEMPTION 
 SECTION 3.01. Notices to Trustee. 

If the Company elects to redeem Notes pursuant to Section 5 or Section 6 of the Notes, it shall notify the Trustee in writing
of the Redemption Date, the Redemption Price and the principal amount of Notes to be redeemed. The Company shall give notice of redemption to the Paying Agent and Trustee at least 45 days but not more than 60 days before the Redemption Date (unless
a shorter notice shall be agreed to by the Trustee in writing), together with an Officers’ Certificate stating that such redemption will comply with the conditions contained herein. 
 SECTION 3.02. Selection of Notes To Be Redeemed. 
 If less than all of the
Notes are to be redeemed at any time, the Trustee will select Notes for redemption as follows: 
 (a) if the Notes are listed on
a national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or 
 (b) if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee in its sole discretion shall deem fair and appropriate; 

provided that, in the case of such partial redemption pursuant to Section 6 of the Notes or an Asset Disposition Offer, the Trustee will
select the Notes on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the procedures of the Depository). 
 No Notes of $2,000 or less shall be redeemed in part. 

  
 -44-

  
 SECTION 3.03. Notice of
Redemption. 
 At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of
redemption by first class mail, postage prepaid, to each Holder whose Notes are to be redeemed at its registered address. At the Company’s request, the Trustee shall forward the notice of redemption in the Company’s name and at the
Company’s expense. Each notice for redemption shall identify the Notes (including the CUSIP number) to be redeemed and shall state: 
 (1) the Redemption Date; 
 (2) the Redemption Price and the amount
of accrued interest, if any, to be paid; 
 (3) the name and address of the Paying Agent; 

(4) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued
interest, if any; 
 (5) that, unless the Company defaults in making the redemption payment, interest on Notes
called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Notes redeemed; 

(6) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after
the Redemption Date, and upon surrender of such Note, a new Note or Notes in aggregate principal amount equal to the unredeemed portion thereof will be issued; 
 (7) if fewer than all the Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and
the aggregate principal amount of Notes to be outstanding after such partial redemption; and 
 (8) the Section
of the Notes pursuant to which the Notes are to be redeemed. 
 The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not
affect the validity of the proceedings for the redemption of any other Note. Notices of redemption may not be conditional. 
 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 due and payable on the Redemption Date and at the Redemption Price plus accrued interest, if any. Upon surrender to the Trustee or Paying Agent, such Notes 

  
 -45-

 
called for redemption shall be paid at the Redemption Price (which shall include accrued interest thereon to the Redemption Date), except that installments of interest, the maturity of which is
on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption.

 SECTION 3.05. Deposit of Redemption Price. 
 On or before 11:00 a.m. New York time on the Redemption Date, the Company shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued interest, if any, of all
Notes to be redeemed on that date. 
 If the Company complies with the preceding paragraph, then, unless the Company defaults in
the payment of such Redemption Price plus accrued interest, if any, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment. 

SECTION 3.06. Notes Redeemed in Part. 
 If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note or Notes in principal
amount equal to the unredeemed portion of the original Note or Notes shall be issued in the name of the Holder thereof upon cancellation of the original Note or Notes. 
 ARTICLE FOUR 
 COVENANTS

 The Company shall duly and punctually pay

Agent (other than the Company or an Affiliate thereof) holds on that date U.S. Legal Tender designated for and sufficient to pay the installment. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day
months. 
 The Company will pay principal of, premium, if any, and interest on, Notes in global form registered in the name of

 SECTION 4.02. Maintenance of Office or Agency. 
 The Company shall maintain
in the Borough of Manhattan, The City of New York, the office or agency required under Section 2.03. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at
any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set
forth in Section 12.02. 
 The Company may also from time to time designate one or more other offices or agencies where the
Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency. The Company may, at its option, pay interest on the Notes by check mailed to Holders of the Notes at their registered addresses as they appear in the Registrar’s books. 

The Company hereby initially designates The Bank of New York Mellon Trust Company, N.A., c/o The Bank of New York Mellon, located at 101

things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each of its Restricted Subsidiaries in accordance with the respective organizational documents of each such
Restricted Subsidiary and the rights (charter and statutory) and material franchises of the Company and each of its Restricted Subsidiaries; provided, however, that the Company shall not be required to preserve any such right,
franchise or corporate, partnership or other existence with respect to any such Restricted Subsidiary if the loss thereof would not, individually or in the aggregate, have a material adverse effect on the business, financial condition or results of
operations of the Company and its Restricted Subsidiaries taken as a whole and provided further that this Section 4.03 shall not prohibit or restrict any sale, transfer or other disposition in compliance with Section 4.15.

any such tax, assessment, charge or claim (a) whose amount, applicability or validity is being contested in good faith by appropriate action and for which appropriate provision has been made or (b) where the failure to effect such payment
would not individually or in the aggregate have a material adverse effect on the ability of the Company or such Subsidiary Guarantors to perform each of their respective obligations hereunder. 

SECTION 4.05. [Intentionally Omitted.] 

SECTION 4.06. Compliance Certificate; Notice of Default. 
 (a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, an Officers’ Certificate signed by the principal executive officer, the principal

Company and each Subsidiary Guarantor has kept, observed, performed and fulfilled its obligations under this Indenture and further stating, as to each such Officer signing such certificate, that to the best of such Officer’s knowledge, the
Company and each Subsidiary Guarantor during such preceding fiscal year has kept, observed, performed and fulfilled each and every such covenant and no Default occurred during such year and at the date of such certificate there is no Default that
has occurred and is continuing or, if such signers do know of such Default, the certificate shall describe its status with particularity. The Company’s fiscal year currently ends on December 31. The Officers’ Certificate shall also
notify the Trustee should the Company elect to change the manner in which it fixes its fiscal year end. 
 (b) The Company shall
deliver to the Trustee as soon as possible and in any event within 30 days after the Company becomes aware of the occurrence of any Default an Officers’ Certificate specifying the Default and describing its status with particularity and the
action proposed to be taken thereto.

If on any date following the Issue Date (i) the Notes have Investment Grade Ratings from both of the Rating Agencies, (ii) no
Default or Event of Default has occurred and is continuing and (iii) the Company has delivered an Officer’s Certificate to the Trustee certifying that the conditions set forth in clauses (i) and (ii) above are satisfied (the

and will be permanently released from their obligations under, Sections 4.10, 4.12, 4.14, 4.15, 4.16, 4.17 and clause (3) of the first paragraph of Section 5.01, and no failure by the Company or any Subsidiary to comply with any of the

 -48-

  
 SECTION 4.08. Waiver of Stay,
Extension or Usury Laws. 
 Each of the Company and each Subsidiary Guarantor covenants (to the extent that it may lawfully
do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company or such Subsidiary
Guarantor from paying all or any portion of the principal of and/or interest on the Notes or the Note Guarantee of any such Subsidiary Guarantor as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture and (to the extent that it may lawfully do so) each hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 SECTION
4.09. Change of Control. 
 If a Change of Control occurs, unless the Company has exercised its right to redeem all of
the then outstanding Notes pursuant to Section 5 of the Notes, each Holder will have the right to require the Company to repurchase all or any part (in integral multiples of $1,000, provided that the remaining principal amount of any
Note repurchased in part must not be less than $2,000) of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest, if any, to the date of purchase. 

Within 30 days following any Change of Control, unless the Company has exercised its right to redeem the then outstanding Notes pursuant
to Section 5 of the Notes, the Company will mail a notice (the “Change of Control Offer”) to each Holder, with a copy to the Trustee, stating: 

(1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such
Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the Change of Control Payment Date (the “Change of Control Payment”);

 (2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such
notice is mailed) (the “Change of Control Payment Date”); 
 (3) that any Note not tendered will
continue to accrue interest; 
 (4) that, unless the Company defaults in making payment therefor, any Note
accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have a Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on
the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date; 

  
 -49-

  
 (6)
that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the second Business Day prior to the Change of Control Payment Date, a telegram, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

(7) that Holders whose Notes are purchased only in part will be issued new Notes in a principal amount equal to the
unpurchased portion of the Notes surrendered; 
 (8) the circumstances and relevant facts regarding such Change
of Control; and 
 (9) the procedures determined by the Company, consistent with this Indenture, that a Holder
must follow in order to have its Notes repurchased. 
 On the Change of Control Payment Date, the Company will, to the extent
lawful: 
 (1) accept for payment all such Notes or portions of Notes (in integral multiples of $1,000,
provided that the remaining principal amounts of any Note repurchased in part must not be less than $2,000) properly tendered and not withdrawn 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 so tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with

 The Paying Agent will promptly mail to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by
book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in
excess thereof. 
 If the Change of Control Payment Date is on or after an interest record date and on or before the related
Interest Payment Date, the accrued and unpaid interest, if any, will be paid to the Persons in whose names the Notes are registered at the close of business on such record date, and no additional interest will be payable to Holders who tender
pursuant to the Change of Control Offer. 
 The Company will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes
validly tendered and not withdrawn under such Change of Control Offer.

 The Company will
comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.09. To the extent that the
provisions of any securities laws or regulations conflict with provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described in this
Indenture by virtue of the conflict. 
 SECTION 4.10. Limitation on Indebtedness. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, Incur any Indebtedness (including Acquired
Indebtedness); provided, however, that the Company and any Restricted Subsidiary may Incur Indebtedness (including Acquired Indebtedness) if, after giving effect thereto (the “Coverage Ratio Exception”): 

(1) the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least 2.00 to 1.00; and

 (2) no Default or Event of Default will have occurred or be continuing or would occur as a consequence of
Incurring the Indebtedness or transactions relating to such Incurrence. 
 The first paragraph of this Section 4.10 will
not prohibit the Incurrence of the following Indebtedness (“Permitted Indebtedness”): 
 (1)
Indebtedness of the Company or any Restricted Subsidiary Incurred pursuant to the Senior Credit Facilities (with letters of credit being deemed to have a principal amount equal to the maximum potential liability thereunder to the Company and its
Restricted Subsidiaries) or a Qualified Receivables Transaction in an aggregate principal amount Incurred pursuant to this clause (1) at any time outstanding not to exceed $4,000.0 million, less the aggregate principal amount of all principal
repayments with the proceeds from Asset Dispositions utilized in accordance with clause (3)(a)(i) of the first paragraph of Section 4.15 that permanently reduce the commitments thereunder; 

(2) Guarantees by the Company or any Subsidiary Guarantor of Indebtedness Incurred in accordance with the provisions of
this Indenture or existing on the Issue Date, or Guarantees by a Foreign Subsidiary of Indebtedness of a Foreign Subsidiary Incurred in accordance with the provisions of this Indenture; provided that in the event such Indebtedness that is
being Guaranteed by the Company or a Subsidiary Guarantor is a Subordinated Obligation or a Guarantor Subordinated Obligation relative to the Note Guarantees, then the related Guarantee shall be subordinated in right of payment to the Notes or a
Note Guarantee, as the case may be; 
 (3) Indebtedness of the Company owing to and held by any Restricted
Subsidiary or Indebtedness of a Restricted Subsidiary owing to and held by the Company or any other Restricted Subsidiary; provided, however, 

  
 -51-

  
 (i) any subsequent
issuance or transfer of Capital Stock or any other event which results in any such Indebtedness being beneficially held by a Person other than the Company or a Restricted Subsidiary of the Company; and 

(ii) any sale or other transfer of any such Indebtedness to a Person other than the Company or a Restricted Subsidiary of the Company;

 shall be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Subsidiary, as the case
may be, not permitted by this clause (3); 
 (4) Indebtedness represented by (a) the Notes issued on
the Issue Date and the Note Guarantees and the 2020 Notes and the Guarantees thereof, and (b) any Indebtedness (other than the Indebtedness described in clauses (1), (2), (3), (5), (7), (8), (9), (10) and (17)) outstanding on the
Issue Date; 
 (5) Indebtedness under Hedging Obligations that are Incurred in the ordinary course of business
(and not for speculative purposes) (1) for the purpose of fixing or hedging interest rate risk with respect to any Indebtedness Incurred without violation of this Indenture, provided that the notional principal amount of such Hedging
Obligations at the time Incurred does not exceed the principal amount of the Indebtedness to which such Hedging Obligations relate; or (2) for the purpose of fixing or hedging currency exchange rate risk, provided that the underlying
Currency Agreements with respect to such Hedging Obligations do not increase the Indebtedness of the Company and its Restricted Subsidiaries outstanding other than as a result of fluctuations in foreign currency exchange rates or by reason of fees,
indemnities and compensation payable thereunder; 
 (6) the Incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness with respect to property or other assets other than Capital Stock or other Investments, in each case to the extent Incurred for the purpose of financing or refinancing all or any part of the purchase price or cost of
acquisition, construction or improvements of property or other assets used or useful in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount not to exceed at any time outstanding the greater of
(a) $250.0 million and (b) 7.5% of Total Tangible Assets at that time; 
 (7) Indebtedness Incurred in
respect of workers’ compensation claims, self-retention or self-insurance obligations, unemployment insurance, performance, release, appeal, surety and similar bonds and related reimbursement obligations and completion guarantees or similar
instruments provided or Incurred by the Company or a Restricted Subsidiary in the ordinary course of business and obligations in connection with participation in government reimbursement or other programs or other similar requirements (in each case,
other than for an obligation for money borrowed); 
 (8) Indebtedness arising from agreements of the Company or a
Restricted Subsidiary providing for indemnification, contribution, earnout, adjustment of purchase price or similar obligations, in each case, Incurred or assumed in connection with the acquisition or disposition of any business, assets or Capital
Stock of a Restricted 

  
 -52-

 
Subsidiary; provided that any amount of such obligations included on the face of the balance sheet of the Company or any Restricted Subsidiary shall not be permitted under this clause (8);

 (9) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or
similar instrument drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five Business Days of Incurrence; 

(10) shares of Preferred Stock of a Restricted Subsidiary issued to the Company or another Restricted Subsidiary;
provided that any subsequent transfer of any Capital Stock or any other event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except
to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of Preferred Stock not permitted by this clause (10); 
 (11) Indebtedness of the Company or a Restricted Subsidiary to the extent the net proceeds thereof are promptly deposited to effect defeasance or covenant defeasance of the Notes pursuant to
Sections 8.02, 8.03 and 8.04 or to effect discharge of this Indenture pursuant to Section 8.01, so long as the other conditions thereunder have been satisfied in full; 

(12) Refinancing Indebtedness with respect to Indebtedness Incurred pursuant to the Coverage Ratio Exception or pursuant
to this clause (12) or Incurred or referred to in clause (4) above, and Indebtedness represented by the Notes, the 2020 Notes and any Guarantees in respect thereof; 

(13) Guarantees given by the Company or any Restricted Subsidiary in respect of Indebtedness of any Special Purpose
Licensed Entity which obligations, when aggregated with the aggregate amount of all then outstanding Investments made under clause (12) of the definition of “Permitted Investment,” do not exceed $150.0 million at any time
outstanding; 
 (14) (a) Indebtedness, including Acquired Indebtedness, of the Company or any Subsidiary
Guarantor incurred in connection with, or in anticipation or contemplation of, an acquisition or merger by the Company or such Subsidiary Guarantor of property used or useful in a Permitted Business (whether through the direct purchase of assets or
the purchase of Capital Stock of, or merger or consolidation with, any Person owning such assets); provided that the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries determined on a pro forma basis for the
Incurrence of such Indebtedness (and the application of the proceeds therefrom), either (A) would have been at least 2.00 to 1 or (B) would have been greater than such Consolidated Coverage Ratio immediately prior to such acquisition; and

 (b) Acquired Indebtedness Incurred by the debtor thereof prior to the time that the debtor thereunder was
acquired (whether by merger, consolidation, acquisition of Capital Stock or otherwise) by the Company or any of its Restricted Subsidiaries, or prior 

  
 -53-

 
to the time that the related asset or property was acquired by the Company or any of its Restricted Subsidiaries, and was not Incurred in connection with, or in anticipation or contemplation of,
such acquisition, and Refinancing Indebtedness thereof, in an aggregate amount not to exceed $200.0 million at any time outstanding; 
 (15) Indebtedness Incurred in connection with any Sale/Leaseback Transaction; provided that the aggregate outstanding amount of all such Indebtedness under this clause (15) does not exceed
$50.0 million at any time outstanding; 
 (16) Indebtedness of Restricted Subsidiaries that are not Subsidiary
Guarantors in an aggregate amount not to exceed $250.0 million at any time outstanding; 
 (17) Indebtedness
under the Existing Notes outstanding on the Issue Date and any Guarantees of the Existing Notes; 
 (18)
Indebtedness arising under any cash pooling arrangement to the extent that the net value thereof (determined by subtracting the borrowings and other withdrawals therefrom from the amount of cash deposited therein) is positive (for purposes of
clarity, it is understood and agreed that, if the net value of any cash pooling arrangement is negative, then any Indebtedness attributable to such negative balance shall not be permitted under this clause (18), but may be Incurred under the
Coverage Ratio Exception or any other clause of “Permitted Indebtedness” to the extent permitted thereby); and 
 (19) in addition to the items referred to in clauses (1) through (18) above, Indebtedness of the Company and its Restricted Subsidiaries in an aggregate outstanding principal amount which, when
taken together with the principal amount of all other Indebtedness Incurred pursuant to this clause (19) and then outstanding (including any renewals, extensions, substitutions, refinancings or replacements of such Indebtedness), will not
exceed $350.0 million at any time outstanding. 
 For purposes of determining compliance with, and the outstanding principal
amount of any particular Indebtedness Incurred pursuant to and in compliance with, this Section 4.10: 
 (1)
subject to clause (2) below, in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness described in the first and second paragraphs of this Section 4.10, the Company, in its sole discretion, will be
permitted to classify such item of Indebtedness on the date of Incurrence and may later reclassify all or a portion of such item of Indebtedness in any manner that complies with this Section 4.10, and only be required to include the amount and
type of such Indebtedness in one of such paragraphs (or, in the case of the second paragraph of this Section 4.10, one of the clauses in such second paragraph); 

(2) all Indebtedness Incurred or outstanding under the Senior Credit Facilities on the Issue Date shall be deemed Incurred
under the Senior Credit Facilities on the Issue Date under clause (1) of “Permitted Indebtedness” and not the Coverage Ratio Exception or any of the other clauses under “Permitted Indebtedness”; 

  
 -54-

  
 (3)
Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included as long as Incurred by a Person that could have
Incurred such Indebtedness; 
 (4) if obligations in respect of letters of credit are Incurred pursuant to the
Senior Credit Facilities and are being treated as Incurred pursuant to the first or second paragraph above and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included; 

(5) the principal amount of any Disqualified Stock of the Company or a Restricted Subsidiary, or Preferred Stock of a
Restricted Subsidiary that is not a Subsidiary Guarantor, will be equal to the greater of its voluntary or involuntary liquidation preference and its maximum fixed repurchase price (not including, in either case, any redemption or repurchase
premium); 
 (6) Indebtedness permitted by this Section 4.10 need not be permitted solely by reference to
one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.10 permitting such Indebtedness; 

(7) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the
amount of the liability in respect thereof determined in accordance with GAAP; and 
 (8) the principal amount of
any Indebtedness outstanding in connection with a Qualified Receivables Transaction is the Receivables Transaction Amount relating to such Qualified Receivables Transaction (which amount shall not include dispositions of self-pay receivables in the
ordinary course of business, which the Company or any of its Restricted Subsidiaries believes in good faith cannot be paid in full). 
 Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of additional Indebtedness and the payment of dividends in the form of additional shares of
Preferred Stock or Disqualified Stock will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 4.10. The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case
of any Indebtedness issued with original issue discount and (ii) the principal amount or, in the case of Preferred Stock or Disqualified Stock, the greater of the voluntary or involuntary liquidation preference and the maximum fixed repurchase
price thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness. 

In addition, the Company will not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness or issue any shares of
Disqualified Stock (other than Non-Recourse Debt and other than Indebtedness of a Receivables Subsidiary in respect of a Qualified Receivables Transaction). If on any date an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness
of such Subsidiary outstanding at such time shall be deemed to be Incurred by a 

  
 -55-

 
Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 4.10, the Company shall be in default of this
Section 4.10). 
 For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of
Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, or, in the case of
revolving credit Indebtedness, the date such Indebtedness was first committed; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable
U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the
principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.10, the maximum amount of Indebtedness that the Company and its
Restricted Subsidiaries may Incur pursuant to this Section 4.10 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. 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 refinanced Indebtedness and refinancing Indebtedness is
denominated that is in effect on the date of such refinancing. In the event that any other provision (including, without limitation, any other covenant or any defined term) of this Indenture requires the calculation of the principal amount of any
Indebtedness, such calculation shall, unless otherwise expressly stated or the context otherwise requires, be made in a manner consistent with the third paragraph, the fourth paragraph and this sixth paragraph of this Section 4.10, mutatis
mutandis. 
 SECTION 4.11. Limitation on Layering. 
 The Company will not, and will not permit any Subsidiary Guarantor to, directly or indirectly, Incur any Indebtedness that is or purports to be by its terms (or by the terms of any agreement governing
such Indebtedness) subordinated to any other Indebtedness of the Company or of such Subsidiary Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly
subordinate to the Notes or the Note Guarantee of such Subsidiary Guarantor with respect to the Notes, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the Company or such Subsidiary
Guarantor, as the case may be. 
 For purposes of the foregoing, no Indebtedness will be deemed to be subordinated or junior in
right of payment to any other Indebtedness of the Company or any Subsidiary Guarantor solely by virtue of being unsecured or secured by a junior priority lien or by virtue of the fact that the holders of such Indebtedness have entered into
intercreditor agreements or similar arrangements giving one or more of such holders priority over the other holders in the collateral held by them. 

  
 -56-

  
 SECTION 4.12. Limitation on
Restricted Payments. 
 The Company will not, and will not permit any of its Restricted Subsidiaries, directly or
indirectly, to: 
 (1) declare or pay any dividend or make any distribution (whether made in cash, securities or
other property) on or in respect of its Capital Stock (including any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) except: 

(a) dividends or distributions payable in Capital Stock of the Company (other than Capital Stock that is Disqualified
Stock) or in options, warrants or other rights to purchase such Capital Stock of the Company; and 
 (b)
dividends or distributions payable to the Company or a Restricted Subsidiary (and if such Restricted Subsidiary is not a Wholly-Owned Restricted Subsidiary, to its other holders of common Capital Stock on a pro rata basis); 

(2) purchase, redeem, retire or otherwise acquire for value any Capital Stock of the Company or any direct or indirect
parent of the Company held by Persons other than the Company or a Restricted Subsidiary (other than in exchange for Capital Stock of the Company (other than Capital Stock that is Disqualified Stock) or in options, warrants, or other such rights to
purchase such Capital Stock of the Company); 
 (3) purchase, repurchase, redeem, defease or otherwise acquire or
retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Obligations or Guarantor Subordinated Obligations (other than (x) such Subordinated Obligations or Guarantor Subordinated
Obligations purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, repurchase, redemption, defeasance or other acquisition or retirement
and (y) such Subordinated Obligations or Guarantor Subordinated Obligations held by the Company or any Restricted Subsidiary); or 
 (4) make any Restricted Investment in any Person 
 (any such dividend, distribution, purchase,
redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) shall be referred to herein as a “Restricted Payment”), if at the time the Company or such
Restricted Subsidiary makes such Restricted Payment: 
 (a) a Default or Event of Default shall have occurred and
be continuing (or would result therefrom); or 
 (b) the Company is not able to Incur an additional $1.00 of
Indebtedness pursuant to the Coverage Ratio Exception after giving effect, on a pro forma basis, to such Restricted Payment; or 

  
 -57-

  
 (c) the
aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date (excluding Restricted Payments permitted by clauses (2)(ii), (3), (4), (8), (9), (10) and (11) below) would exceed
the sum (the “Restricted Payments Basket”) of (without duplication): 
 (i) 50% of Consolidated
Net Income for the period (treated as one accounting period) from the beginning of the fiscal quarter which includes the Issue Date therein to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which
financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit); plus 
 (ii) 100% of the aggregate Net Cash Proceeds and the Fair Market Value of Qualified Proceeds received by the Company from the issue or sale of its Capital Stock (other than Capital Stock that is
Disqualified Stock) or other capital contributions to the common equity of the Company subsequent to the Issue Date (other than (x) Net Cash Proceeds received from an issuance or sale of such Capital Stock to a Subsidiary of the Company or an
employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or Guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with
cash on or prior to the date of determination and (y) Net Cash Proceeds received by the Company from the issue or sale of its Capital Stock to the extent used to redeem Notes in compliance with Section 6 of the Notes); plus

 (iii) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the
Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the Issue Date of any Indebtedness of the Company or its Restricted Subsidiaries issued after the Issue Date convertible or
exchangeable for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any cash, or the Fair Market Value of any other property, distributed by the Company or its Restricted Subsidiaries upon such conversion or exchange);
plus 
 (iv) the amount equal to the net reduction in Restricted Investments made by the Company or any of
its Restricted Subsidiaries in any Person resulting from: 
 (A) repurchases or redemptions of such Restricted
Investments by such Person, proceeds realized upon the sale of such Restricted Investment to an unaffiliated purchaser, repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to the
Company or any Restricted Subsidiary (other than expressly for reimbursement of tax payments) not to exceed the aggregate amount of all such Restricted Investments made since the Issue Date; or 

(B) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the
definition of 

  
 -58-

 
“Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made since the Issue Date by the Company or any Restricted Subsidiary in
such Unrestricted Subsidiary, 
 which amount in each case under this clause (iv) was included in the calculation of the
amount of Restricted Payments; provided, however, that no amount will be included under clause (iv)(A) of this paragraph to the extent it is already included in Consolidated Net Income. 

The provisions of the preceding paragraph will not prohibit: 

(1) the payment of any dividend within 60 days after the date of declaration of such dividend if the dividend would have
been permitted on the date of declaration; 
 (2) if no Default or Event of Default shall have occurred and be
continuing, the acquisition, retirement, defeasance or purchase of any shares of Capital Stock of the Company either (i) solely in exchange for shares of Capital Stock of the Company (other than Disqualified Stock) or (ii) through the
application of the net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Company) of shares of Capital Stock of the Company (other than Capital Stock that is Disqualified Stock with respect to the Notes issued
under such Indenture) (provided that the amount of net proceeds so applied shall not be applied toward the Restricted Payments Basket); 
 (3) if no Default or Event of Default shall have occurred and be continuing, the acquisition, making of any principal payment, redemption, defeasance or other retirement of any Subordinated Obligations
either (i) solely in exchange for shares of Capital Stock of the Company (other than Capital Stock that is Disqualified Stock), (ii) through the application of net proceeds of a substantially concurrent sale for cash (other than to a
Subsidiary of the Company) of (a) shares of Capital Stock of the Company (other than Capital Stock that is Disqualified Stock) (provided that the amount of net proceeds so applied shall not be applied toward the Restricted Payments
Basket) or (b) Refinancing Indebtedness permitted to be Incurred pursuant to Section 4.10, (iii) upon a Change of Control or in connection with an Asset Disposition to the extent required by the agreement governing such Subordinated
Obligations but only if the Company shall have complied with Sections 4.09 or 4.15, as applicable, and, if applicable, purchased all Notes validly tendered pursuant to the relevant offer prior to acquiring, paying, redeeming, defeasing or otherwise
retiring such Subordinated Obligations or (iv) to the extent such Subordinated Obligations constitute Acquired Indebtedness not Incurred in connection with or in anticipation or contemplation of the underlying acquisition or merger or the
applicable Person becoming a Restricted Subsidiary; 
 (4) so long as no Default or Event of Default shall have
occurred and be continuing, repurchases by the Company of Common Stock of the Company from officers, directors and employees of the Company or any of its Subsidiaries or their authorized representatives upon the death, disability or termination of
employment of such employees or termination of their seat on the board of the Company, in an aggregate amount not to exceed $15.0 million in any calendar year; 

  
 -59-

  
 (5)
repurchases of Capital Stock deemed to occur upon exercise of stock options, warrants or other convertible or exercisable securities if such Capital Stock represents a portion of the exercise or conversion price thereof; 

(6) so long as no Default or Event of Default shall have occurred and be continuing, payments to holders of the
Company’s Capital Stock in lieu of issuance of fractional shares of its Capital Stock or to dissenting shareholders if required by applicable law; 
 (7) the distribution of Capital Stock of an Unrestricted Subsidiary of the Company to holders of Capital Stock of the Company; 

(8) so long as no Default or Event of Default shall have occurred and shall be continuing, purchases or other acquisitions
or retirements by the Company or any of its Restricted Subsidiaries of the Company’s Common Stock for aggregate consideration not to exceed $1,200.0 million; 

(9) so long as no Default or Event of Default shall have occurred and be continuing, the making of any Restricted Payments
if, at the time of the making of such payments, and after giving pro forma effect thereto (including, without limitation, the Incurrence of any Indebtedness to finance such payment), the Consolidated Total Leverage Ratio would not exceed 3.50
to 1.00; 
 (10) the purchase, redemption, defeasance or other retirement of Existing Notes to the extent such
purchase, redemption, defeasance or other retirement would constitute a Restricted Payment; and 
 (11)
additional Restricted Payments not to exceed $500.0 million in the aggregate since the Issue Date. 
 The amount of all
Restricted Payments (other than cash) shall be the Fair Market Value on the date of such Restricted Payment of the asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be,
pursuant to such Restricted Payment. If the Company or a Restricted Subsidiary makes a Restricted Payment which, at the time of the making of such Restricted Payment, would in the good faith determination of the Company be permitted under the
provisions of this Indenture, such Restricted Payment shall be deemed to have been made in compliance with this Indenture notwithstanding any subsequent adjustments or restatements made in good faith to the Company’s financial statements.

 SECTION 4.13. Limitation on Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or suffer to exist any Lien (other than Permitted Liens) of any nature whatsoever
against any assets or property of the Company or any Restricted Subsidiary (including Capital Stock of Restricted Subsidiaries), whether owned on the Issue Date or 

  
 -60-

 
acquired after that date, which Lien secures Indebtedness or trade payables, unless contemporaneously therewith: 

(1) in the case of any Lien securing an obligation that ranks pari passu with the Notes or a Note Guarantee,
effective provision is made to secure the Notes or such Note Guarantee, as the case may be, at least equally and ratably with or prior to such obligation with a Lien on the same collateral; and 

(2) in the case of any Lien securing an obligation that is subordinated in right of payment to the Notes or a Note
Guarantee, effective provision is made to secure the Notes or such Note Guarantee, as the case may be, with a Lien on the same collateral that is prior to the Lien securing such subordinated obligation; 

in each case, for so long as such obligation is secured by such Lien. 
 SECTION 4.14. Limitation on Restrictions on Distributions from Restricted Subsidiaries. 
 The Company will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability
of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital Stock or pay
any Indebtedness or other obligations owed to the Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions
being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock); 
 (2) make any loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other
Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or 
 (3) transfer any of its property or assets to the Company or any Restricted Subsidiary (it being understood that such transfers shall not include any type of transfer described in clause (1) or
(2) above). 
 The preceding provisions will not prohibit: 

(i) any encumbrance or restriction pursuant to an agreement in effect at or entered into on the Issue Date, including,
without limitation, this Indenture and the 2020 Indenture, the Notes issued thereunder and the Guarantees thereof, the Existing Notes and the Guarantees thereof and the related indentures and the Senior Credit Facilities, in each case, as in effect
on such date; 

  
 -61-

  
 (ii)
any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement relating to any Capital Stock or Indebtedness Incurred by a Restricted Subsidiary on or before the date on which such Restricted Subsidiary was acquired
(whether by merger, consolidation, acquisition of Capital Stock or otherwise) by the Company or a Restricted Subsidiary (other than Capital Stock or Indebtedness that was Incurred as consideration in, or to provide all or any portion of the funds
utilized to consummate, the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or acquired by the Company or in contemplation of the transaction) and outstanding on such date;
provided that any such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired and property acquired by such Restricted Subsidiary
after its date of acquisition; 
 (iii) any encumbrance or restriction with respect to a Restricted Subsidiary
pursuant to an agreement effecting an amendment, restatement, modification, renewal, increase, refunding, replacement or refinancing of an agreement referred to in clause (i) or (ii) of this paragraph or this clause (iii); provided,
however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement, amendment, restatement, modification, renewal, increase, refunding, replacement or refinancing are not, in the good
faith judgment of the Company’s Board of Directors, materially less favorable, taken as a whole, to the Holders of the Notes than the encumbrances and restrictions contained in such agreements referred to in clause (i) or (ii) of this
paragraph on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was acquired (whether by merger, consolidation, acquisition of Capital Stock or otherwise) by the Company or a Restricted Subsidiary, whichever is
applicable; 
 (iv) (a) purchase money obligations for property acquired in the ordinary course of business,
(b) Capitalized Lease Obligations permitted under this Indenture, (c) industrial revenue bonds or (d) operating leases, in each case, that impose encumbrances or restrictions of the nature described in clause (3) of the first
paragraph of this Section 4.14 on the property so acquired; 
 (v) any restriction with respect to a
Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement entered into for the direct or indirect sale or disposition (whether by sale, merger, consolidation, acquisition of Capital Stock or otherwise) of the Capital
Stock or assets of such Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition; 
 (vi) customary non-assignment provisions in leases and other agreements entered into by the Company or any Restricted Subsidiary in the ordinary course of business; 

(vii) encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or
order; 

  
 -62-

  
 (viii)
customary encumbrances or restrictions existing under or by reason of provisions in joint venture, partnership (limited or general), limited liability company or similar agreements required in connection with the entering into of such transaction;

 (ix) customary restrictions imposed on the transfer, licensing, sub-licensing and assignment of intellectual
property and of intellectual property licenses; 
 (x) restrictions relating to any Lien permitted under this
Indenture imposed by the holder of such Lien; 
 (xi) any other Indebtedness or contractual requirements Incurred
with respect to a Qualified Receivables Transaction relating exclusively to the assets that are the subject of the Qualified Receivables Transaction; 
 (xii) in the case of Restricted Subsidiaries that are not Subsidiary Guarantors, restrictions imposed under instruments governing Indebtedness Incurred pursuant to the definition of “Permitted
Indebtedness”; 
 (xiii) in the case of any Restricted Subsidiary that is not a Subsidiary Guarantor,
restrictions under the constitutive documents governing such Subsidiary: (A) with respect to Subsidiaries existing on the Issue Date; and (B) with respect to Subsidiaries created or acquired after the Issue Date: (1) prohibiting such
Subsidiary from Guaranteeing Indebtedness of the Company or another Subsidiary; (2) on dividend payments and other distributions solely to permit pro rata dividends and other distributions in respect of any Capital Stock of such
Subsidiary; (3) limiting transactions with the Company or another Subsidiary to those with terms that are fair and reasonable to such Subsidiary and no less favorable to such Subsidiary than could have been obtained in an arm’s-length
transaction with an unrelated third party; and (4) limiting such Subsidiary’s ability to transfer assets or Incur Indebtedness without the consent of the holders of the Capital Stock of such Subsidiary; and 

(xiv) any encumbrances or restrictions imposed by any amendments, restatements, modifications, renewals, increases,
restrictions, encumbrances, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (i) through (xiii) above; provided that such amendments, restatements, modifications, renewals,
increases, restrictions, encumbrances, refundings, replacements or refinancings are, in the good faith judgment of the Company’s Board of Directors, no more materially restrictive with respect to such encumbrances and restrictions than those
prior to such amendment or refinancing. 
 SECTION 4.15. Limitation on Sales of Assets and Subsidiary Stock. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless: 

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration (both cash and non cash) equal
to not less than the Fair Market Value (such 

  
 -63-

 
Fair Market Value to be determined on the date of contractually agreeing to such Asset Disposition) of the shares and assets subject to such Asset Disposition; 

(2) at least 75% of the consideration from such Asset Disposition received by the Company or such Restricted Subsidiary,
as the case may be, is in the form of cash or Cash Equivalents or Replacement Assets. For purposes of this clause (2), each of the following shall be deemed to be cash: 

(a) any liabilities (as shown on the face of the Company’s or such Restricted Subsidiary’s then most recent
balance sheet), of the Company or any Restricted Subsidiary (other than contingent liabilities and Subordinated Obligations) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company
or such Restricted Subsidiary from further liability; 
 (b) any securities, notes or other obligations received
by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion) within 180 days of the closing of such Asset
Disposition; and 
 (c) any Designated Noncash Consideration received by the Company or any Restricted Subsidiary
in such Asset Disposition having an aggregate Fair Market Value (as determined in good faith by the Board of Directors of the Company), taken together with all other Designated Noncash Consideration received pursuant to this clause (c) that is
at that time outstanding, not to exceed $100.0 million (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received without giving effect to subsequent changes in value); and 

(3) an amount equal to 100% of the Net Available Cash from such Asset Disposition: 

(a) first, is applied by the Company or such Restricted Subsidiary, as the case may be, 

(i) to the extent the Company or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of
any Bank Indebtedness), to prepay, repay or purchase such Bank Indebtedness of the Company or of a Restricted Subsidiary within 365 days from the date of such Asset Disposition (such period, the “Application Period”), unless to the
extent such Net Available Cash is otherwise used in accordance with clause (ii); provided, however, that, in connection with any prepayment, repayment or purchase of any such Indebtedness pursuant to this clause (a), the Company or
such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment (if any) to be permanently 

  
 -64-

 
reduced in an amount equal to the principal amount so prepaid, repaid or purchased, or 
 (ii) to the extent the Company or such Restricted Subsidiary elects, to invest in Replacement Assets within the applicable Application Period; and 

(b) second, to the extent of the balance of the Net Available Cash after application in accordance with
(a) above (such balance, “Excess Proceeds”), is applied by the Company or such Restricted Subsidiary, as the case may be, toward an offer to purchase Notes as set forth in the next succeeding paragraph; 

provided, however, that pending the final application of any such Net Available Cash in accordance with clause (a) or
clause (b) above, the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture. 

On the 366th day after an Asset Disposition (or such earlier date, if any, as the Board of Directors of the Company or such Restricted
Subsidiary determines that the Net Available Cash will not be applied in accordance with clause (3)(a) of the first paragraph of this Section 4.15), if the aggregate amount of Excess Proceeds exceeds $50.0 million, the Company will be
required to make an offer (“Asset Disposition Offer”) to all Holders of Notes and, to the extent required by the terms of other Senior Indebtedness, to all holders of other Senior Indebtedness outstanding with similar provisions
requiring the Company to make an offer to purchase such Senior Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Notes”) to purchase the maximum principal amount of Notes and any such Pari Passu Notes to which
the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes and Pari Passu Notes plus accrued and unpaid interest to the date of
purchase, in accordance with the procedures set forth herein or the agreements governing the Pari Passu Notes, as applicable, in each case in integral multiples of $1,000 in principal amount (provided that the unpurchased portion of any Note
shall not be less than $2,000 in principal amount) or, in the case of Pari Passu Notes, in such other integral multiples as may be specified in the agreements governing the Pari Passu Notes. To the extent that the aggregate amount of Notes and Pari
Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants
contained in this Indenture. If the aggregate principal amount of Notes and Pari Passu Notes validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes
and the holders, trustees or similar representatives, as the case may be, of Pari Passu Notes shall select the Pari Passu Notes to be purchased on a pro rata basis on the basis of the aggregate principal amount of such tendered Notes and Pari
Passu Notes. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero. 
 Each
Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five
Business Days after the 

  
 -65-

 
termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Company will purchase the principal amount of Notes and Pari Passu Notes required
to be purchased pursuant to this Section 4.15 (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Notes and Pari Passu Notes validly tendered in response
to the Asset Disposition Offer. 
 Upon the commencement of an Asset Disposition Offer, the Company shall send, by first class
mail, a notice to the Trustee and to each Holder at its registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Notes pursuant to the Asset Disposition Offer. Any Asset Disposition Offer
shall be made to all Holders. The notice, which shall govern the terms of the Asset Disposition Offer, shall state: 
 (1) that the Asset Disposition Offer is being made pursuant to this Section 4.15; 
 (2) the Asset Disposition Offer Amount and the Asset Disposition Purchase Date; 
 (3) that any Notes not tendered or accepted for payment shall continue to accrete or accrue interest; 
 (4) that, unless the Company defaults in making such payment, any Notes accepted for payment pursuant to the Asset Disposition Offer shall cease to accrete or accrue interest after the Asset Disposition
Purchase Date; 
 (5) that Holders electing to have a Note purchased pursuant to the Asset Disposition Offer may
only elect to have all of such Note purchased and may not elect to have only a portion of such Note purchased; 

(6) that Holders electing to have a Note purchased pursuant to any Asset Disposition Offer shall be required to surrender
the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed, or transfer by book-entry transfer, to the Company, a depository, if appointed by the Company, or the Paying Agent at the address
specified in the notice at least three days before the Asset Disposition Purchase Date; 
 (7) that Holders shall
be entitled to withdraw their election if the Company, the Depository or the Paying Agent, as the case may be, receives, not later than the second business day prior to the Asset Disposition Purchase Date, a notice 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 surrendered by Holders exceeds the Asset Disposition Offer Amount,
the Company shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by 

  
 -66-

 
the Company so that only Notes in denominations of $1,000, or integral multiples thereof, shall be purchased); 

(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); and 
 (10) all other
procedures, if any, determined by the Company, consistent with this Indenture, that a Holder must follow in order to have its Notes purchased in the Asset Disposition Offer. 
 If the Asset Disposition Purchase Date is on or after an interest record date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a
Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Disposition Offer. 

On or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis
to the extent necessary, the Asset Disposition Offer Amount of Notes and Pari Passu Notes or portions of such Notes and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the
Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Notes so validly tendered and not properly withdrawn, in each case in integral multiples of $1,000 in principal amount (provided that the
unpurchased portion of any Note shall not be less than $2,000 in principal amount) or, in the case of Pari Passu Notes, in such other integral multiples as may be specified in the agreements governing such Pari Passu Notes. The Company will deliver
to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.15 and, in addition, the Company will deliver all certificates and
notes required, if any, by the agreements governing the Pari Passu Notes. The Company or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Asset Disposition Offer Period)
mail or deliver to each tendering Holder of Notes or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or
lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Company, will authenticate and mail or deliver such new
Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. In addition,
the Company will take any and all other actions required by the agreements governing the Pari Passu Notes. Any Note not so accepted will be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the
results of the Asset Disposition Offer on or promptly following the Asset Disposition Purchase Date. 
 In the event of the
transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under Article 5, which transaction does not constitute a Change of Control,
the 

  
 -67-

 
successor company shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this Section 4.15, and shall comply
with the provisions of this Section 4.15 with respect to such deemed sale as if it were an Asset Disposition. In addition, the Fair Market Value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall
be deemed to be Net Available Cash for purposes of this Section 4.15. 
 The Company will comply, to the extent applicable,
with the requirements of Rule 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.15. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of any conflict.

 SECTION 4.16. Limitation on Affiliate Transactions. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or conduct any transaction (including the purchase, sale, lease or exchange of any
property or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) involving aggregate consideration in excess of $10.0 million unless: 

(1) the terms of such Affiliate Transaction are no less favorable, taken as a whole, to the Company or such Restricted
Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate; and 

(2) in the event such Affiliate Transaction involves an aggregate consideration in excess of $35.0 million, the terms of
such transaction have been approved by a majority of the members of the Board of Directors of the Company and by a majority of the members of such Board of Directors having no personal stake in such transaction, if any (and such majority or
majorities, as the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (1) above). 

The preceding paragraph will not apply to: 
 (1) any Restricted Payment permitted to be made pursuant to Section 4.12 or any Investment described in the definition of “Permitted Investments”; 

(2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the
funding of, employment agreements and other compensation arrangements, options to purchase Capital Stock of the Company, stock purchase, ownership or option plans, long-term incentive plans, stock appreciation rights plans, participation plans or
similar employee or director benefits plans provided on behalf of directors, officers, consultants and employees of the Company and its Subsidiaries, in each case, as approved by the Board of Directors of the Company; 

  
 -68-

  
 (3)
loans or advances to employees, consultants, officers or directors in the ordinary course of business of the Company or any of its Restricted Subsidiaries (including for travel, entertainment, moving or relocation) or Guarantees in respect thereof
or otherwise made on their behalf (including payment on any such Guarantees) made in compliance with applicable law but in any event not to exceed $15.0 million in the aggregate outstanding (without giving effect to the forgiveness of any such loan)
at any one time with respect to all loans or advances made since the Issue Date; 
 (4) any transaction between
the Company and a Restricted Subsidiary or between Restricted Subsidiaries, and Guarantees issued by the Company or a Restricted Subsidiary for the benefit of the Company, a Restricted Subsidiary and/or a Special Purpose Licensed Entity, as the case
may be, in accordance with Sections 4.10 and 4.13; 
 (5) the payment of reasonable and customary fees to
directors, and indemnity provided on behalf of, directors, officers, employees or consultants, of the Company or any of its Subsidiaries; 
 (6) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any agreement to which the Company or any of its Restricted Subsidiaries is a party as of or on
the Issue Date, as these agreements may be amended, modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension or renewal entered into after the Issue Date
will be permitted to the extent that its terms are not more materially disadvantageous, taken as a whole, to the Holders of the Notes than the terms of the agreements in effect on the Issue Date; 

(7) transactions entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business
(including, without limitation, management contracts and payments pursuant to management contracts) with any Person (including, without limitation, any joint venture, limited or general partnership, limited liability company or similar business
entity) that owns or has any rights to use property or assets used or useful in a Permitted Business; 
 (8)
sales of Receivables, or participations therein, in connection with any Qualified Receivables Transaction; and 

(9) transactions relating to any cash pooling arrangement. 
 SECTION 4.17. Conduct of Business. 
 The Company will not, and will not
permit any Restricted Subsidiary to, engage in any other business that is not a Permitted Business. 
 SECTION 4.18. SEC Reports.

 Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, to the extent permitted by the Exchange Act, 

  
 -69-

 
the Company will file or furnish with the SEC, and make available to the Trustee and the registered Holders of the Notes, the annual reports and the information, documents and other reports (or
copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act within the time periods specified therein or in the relevant forms. In the event that
the Company is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Company will nevertheless make available such Exchange Act information to the Trustee and Holders of Notes as if the Company
were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein. 
 If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably
detailed presentation, (a) in the footnotes to the financial statements and (b) in Management’s Discussion and Analysis of Results of Operations and Financial Condition, of the financial condition and results of operations of the
Company and its Restricted Subsidiaries. 
 For purposes of this Section 4.18, the Company and the Subsidiary Guarantors
will be deemed to have furnished the reports to the Trustee and the Holders of Notes as required by this Section 4.18 if they have filed or furnished such reports with the SEC via the EDGAR (or successor or similar) filing system and such
reports are publicly available. 
 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 Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 SECTION 4.19. Future Subsidiary
Guarantors. 
 The Company will not permit any Restricted Subsidiary to Guarantee the payment of any Indebtedness of the
Company or any Indebtedness of any other Restricted Subsidiary (other than a Guarantee by a Foreign Subsidiary of Indebtedness of a Foreign Subsidiary or a Guarantee by a Receivables Subsidiary), unless such Restricted Subsidiary simultaneously
executes and delivers a supplemental indenture pursuant to which such Restricted Subsidiary will unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest on the Notes and
all other obligations under this Indenture on a senior basis; provided that if such Indebtedness is by its express terms subordinated in right of payment to the Notes or a Note Guarantee, any Guarantee of such Restricted Subsidiary with
respect to such Indebtedness shall be subordinated in right of payment to such Restricted Subsidiary’s Note Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes or the Note Guarantees, as the case may be.

 The obligations of a Subsidiary Guarantor under its Note Guarantee will be limited as necessary to prevent its Note Guarantee
from constituting a fraudulent conveyance or fraudulent transfer under applicable law. 

  
 -70-

  
 Thereafter, such
Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture. 
 Notwithstanding the preceding paragraph, any
Note Guarantee of a Subsidiary Guarantor will provide by its terms that it will be automatically and unconditionally released and discharged under the circumstances set forth in Section 11.05. The form of the Note Guarantee is attached hereto
as Exhibit C. 
 ARTICLE FIVE 
 MERGER AND CONSOLIDATION 
 SECTION 5.01. Merger and Consolidation. 

The Company will not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to, any
Person, unless: 
 (1) the resulting, surviving or transferee Person (the “Successor
Company”) will be a corporation organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and the Successor Company (if not the Company) will expressly assume, by
supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes and this Indenture; 

(2) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the
Successor Company or any Subsidiary of the Successor Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and
be continuing; 
 (3) immediately after giving effect to such transaction and any related financing, the
Successor Company would be able to Incur at least an additional $1.00 of Indebtedness pursuant to the Coverage Ratio Exception; 
 (4) each Subsidiary Guarantor (unless it is the other party to the transactions above, in which case clause (1) shall apply or unless the Company is the Successor Company) shall have by supplemental
indenture confirmed that its Note Guarantee shall apply to such Successor Company’s obligations in respect of this Indenture and the Notes; and 
 (5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indentures (if
any) comply with this Indenture. 
 For purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer,
or other disposition of all or substantially all of the properties and assets of one or more 

  
 -71-

 
Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the
Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 
 Notwithstanding the foregoing, the sale, conveyance, assignment, transfer or other disposition of assets of any Subsidiary in connection with a Qualified Receivables Transaction that complies with the
other provisions of this Indenture shall not constitute the sale, conveyance, assignment, transfer or other disposition of all or substantially all the assets of the Company or such Subsidiary for purposes of this Section 5.01. 

The predecessor Company will be released from its obligations under this Indenture and the Successor Company will succeed to, and be
substituted for, and may exercise every right and power of, the Company under this Indenture, but, in the case of a lease of all or substantially all its assets, the predecessor Company will not be released from the obligation to pay the principal
of and interest on the Notes. 
 Notwithstanding the preceding clause (3), (w) the Company may effect a reorganization
described in the proviso to the definition of “Change of Control,” (x) any Restricted Subsidiary may consolidate with, merge with or into or transfer all or part of its properties and assets to the Company, (y) the Company may
merge with or into an Affiliate incorporated solely for the purpose of reincorporating the Company in another jurisdiction and (z) the Company may consolidate with, merge with or into or transfer all or part of its properties and assets to a
Subsidiary Guarantor. 
 In addition, the Company will not permit any Subsidiary Guarantor to consolidate with or merge with or
into any Person (other than another Subsidiary Guarantor or the Company) and will not permit the conveyance, transfer or lease of substantially all of the assets of any Subsidiary Guarantor to any Person (other than another Subsidiary Guarantor or
the Company) unless: 
 (1) (a) the resulting, surviving or transferee Person will be a corporation,
partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and such Person (if not such Subsidiary Guarantor) will expressly
assume, by supplemental indenture, executed and delivered to the Trustee, all the obligations of such Subsidiary Guarantor under its Note Guarantee; (b) immediately after giving effect to such transaction (and treating any Indebtedness that
becomes an obligation of the resulting, surviving or transferee Person or any Restricted Subsidiary as a result of such transaction as having been Incurred by such Person or such Restricted Subsidiary at the time of such transaction), no Default of
Event of Default shall have occurred and be continuing; and (c) the Company will have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such
supplemental indentures comply with this Indenture; or 
 (2) the transaction is made in compliance with
Section 4.15.

 ARTICLE SIX 

DEFAULT AND REMEDIES 
 SECTION
6.01. Events of Default. 
 Each of the following is an Event of Default (each an “Event of Default”):

 (1) default in any payment of interest on any Note issued and outstanding under the Indenture when due,
continued for 30 days; 
 (2) default in the payment of principal of or premium, if any, on any Note issued and
outstanding under the Indenture when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; 
 (3) failure by the Company or any Subsidiary Guarantor to comply with its obligations under Article Five; 
 (4) failure by the Company to comply for 30 days after written notice with any of its obligations under the covenants described under Sections 4.09 through 4.19 (in each case, other than a failure to

 (5) failure by the Company to comply for 60 days after written notice with its other agreements contained in this Indenture; 

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured
or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or a
Restricted Subsidiary, whether such Indebtedness or Guarantee exists on, or is created after, the Issue Date, which default: 
 (a) is caused by a failure to pay principal at final maturity of such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“payment default”); or

 (b) results in the acceleration of such Indebtedness prior to its final maturity (the
“cross-acceleration provision”); 
 and, in each case, the principal amount of any such Indebtedness, together
with the principal amount of any other such Indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates $75.0 million or more; 

(7) (a) the Company or a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 

  
 -73-

  
 (i)
commences a voluntary case or proceeding; 
 (ii) consents to the entry of judgment, decree or order for relief
against it in an involuntary case or proceeding; 
 (iii) consents to the appointment of a Custodian of it or for
any substantial part of its property;

(i) is for relief in an involuntary case against the Company or a Significant Subsidiary pursuant to or within the meaning
of any Bankruptcy Law;

or a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law; or 
 (iii) orders the
winding up or liquidation of the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would
constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law; 
 and in the case of each of (i),
(ii) and (iii) such order, decree or relief remains unstayed and in effect for 60 days; 
 (8) failure
by the Company or any Significant Subsidiary to pay the uninsured portion of final judgments aggregating in excess of $75.0 million, which judgments are not paid, discharged or stayed for a period of 60 days (the “judgment default
provision”); 
 (9) any Note Guarantee of a Significant Subsidiary that is a Subsidiary Guarantor ceases
to be in full force and effect (except as contemplated by the terms of this Indenture) or is declared null and void in a judicial proceeding or any Subsidiary Guarantor that is a Significant Subsidiary or group of Subsidiary Guarantors that taken
together would constitute a Significant Subsidiary denies or disaffirms its or their, as the case may 

  
 -74-

 
be, obligations under this Indenture or its Note Guarantee or their Note Guarantees, as the case may be. 
 However, a default under clauses (4) and (5) of this paragraph will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the Notes outstanding notify
the Company of the default and the Company does not cure such default within the time specified in clauses (4) and (5) of this paragraph after receipt of such notice. 

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or is
effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 
 SECTION 6.02. Acceleration. 
 If an Event of Default (other than an Event
of Default with respect to the Company of the type described in clause (7) of Section 6.01) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Notes by
notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon such a declaration,
such principal, premium, if any, and accrued and unpaid interest will be due and payable immediately. 
 In the event of a
declaration of acceleration of the Notes because an Event of Default described in clause (6) of Section 6.01 has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the default or
payment default triggering such Event of Default pursuant to clause (6) of Section 6.01 shall be remedied or cured by the Company or a Restricted Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the
declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except
nonpayment of principal, premium, if any, or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived. 
 If an Event of Default with respect to the Company described in clause (7) of Section 6.01 occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the
Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. 
 SECTION
6.03. Other Remedies. 
 If a Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding
at law or in equity to collect the payment of principal of or 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. To the fullest extent permitted by

  
 -75-

 
applicable law, a delay or omission by the Trustee or any Noteholder in exercising any right or remedy accruing upon a Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Default, no remedy is exclusive of any other remedy and all available remedies are cumulative to the fullest extent permitted by applicable law. 
 SECTION 6.04. Waiver of Past Defaults. 
 The Holders of a majority in
principal amount of the outstanding Notes by notice to the Trustee may (a) waive, by their consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), an existing
Default or Event of Default and its consequences, except a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on a Note, and (b) rescind any such acceleration with respect to the Notes and its
consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the
Notes that have become due solely by such declaration of acceleration, have been cured or waived. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any consequent right. 
 SECTION 6.05. Control by Majority. 

The Holders of not less than a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture,
that the Trustee determines may be unduly prejudicial to the rights of any other Noteholder, or that may involve the Trustee in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. 
 In the event the Trustee takes any action or follows any direction pursuant to this
Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against any loss or expense caused by taking such action or following such direction. 
 SECTION 6.06. Limitation on Suits. 
 Except to enforce the right to receive
payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in principal amount of outstanding Notes have requested the Trustee to pursue the remedy; 

(3) such Holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

  
 -76-

  
 (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) the Holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day
period. 
 A Noteholder may not use this Indenture to affect, disturb or prejudice the rights of another Noteholder or to obtain
a preference or priority over such other Noteholder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Noteholders). 

SECTION 6.07. Rights of Holders To Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on a Note, on or after the respective due dates expressed in such Note, 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 the Holder. 
 SECTION 6.08. Collection Suit by Trustee. 
 If a Default in payment of
principal or interest specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any other obligor on the Notes for the whole
amount of principal and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per
annum specified in the last paragraph of Section 4.01 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 may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Noteholders allowed in any judicial proceedings relating to the Company, its creditors or its property and
shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Noteholder to
make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due to it for the compensation, expenses, disbursements and advances of
the Trustee, its agent and counsel, and any other amounts due 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 Noteholder any plan
of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such

  
 -77-

 
proceeding. The Trustee shall be entitled to participate as a member of any official committee of creditors in the matters as it deems necessary or advisable. 

SECTION 6.10. Priorities. 
 If the Trustee collects any money or property pursuant to this Article Six, it shall pay out the money or property in the following order: 

First: to the Trustee for amounts due under Section 7.07; 

Second: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind, according to
the amounts due and payable on the Notes for interest; 
 Third: to Holders for principal amounts due and unpaid
on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal; and 
 Fourth: to the Company or, if applicable, the Guarantors, as their respective interests may appear. 
 The Trustee, upon prior notice to the Company, may fix a record date and payment date for any payment to Noteholders 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 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 a Holder or Holders
of more than 10% in principal amount of the outstanding Notes.

which may be incurred therein or thereby.

 SECTION 7.03. Individual Rights of Trustee. 
 The Trustee in its individual
or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, its Subsidiaries or their respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like
rights. However, the Trustee must comply with Sections 7.10 and 7.11. 
 SECTION 7.04. Trustee’s Disclaimer. 

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or any document issued in connection with the sale of Notes or any statement in

of the Noteholders. 

  
 -81-

  
 SECTION 7.06. Reports by Trustee to
Holders. 
 Within 60 days after each May 15 beginning with May 15, 2011, the Trustee shall, to the extent that
any of the events described in TIA § 313(a) occurred within the previous twelve months, but not otherwise, mail to each Noteholder a brief report dated as of such date that complies with TIA § 313(a). The Trustee also shall
comply with TIA §§ 313(b), 313(c) and 313(d). 
 The Company shall notify the Trustee if the Notes become listed
on any securities exchange or of any delisting thereof. 
 SECTION 7.07. Compensation and Indemnity. 

The Company shall pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in
writing for its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable disbursements, expenses and
advances (including reasonable fees and expenses of counsel) incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s negligence, bad
faith or willful misconduct. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel. 
 The Company and the Guarantors, jointly and severally, shall indemnify each of the Trustee or any predecessor Trustee and its agents, employees, officers, stockholders and directors for, and hold them
harmless against, any and all loss, damage, claims including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), liability or expense incurred by them except for such actions to the extent caused by any
negligence, bad faith or willful misconduct on their part, arising out of or in connection with the acceptance or administration of this trust including the reasonable costs and expenses of defending themselves against or investigating any claim or
liability in connection with the exercise or performance of any of the Trustee’s rights, powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee or any of its agents, employees,
officers, stockholders and directors of which a Responsible Officer has received notice for which it may seek indemnity. The Company may, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), defend the claim
and the Trustee shall cooperate in the defense. The Trustee and its agents, employees, officers, stockholders and directors subject to the claim may have one firm of separate counsel (plus, with the prior written consent of the Company (not to be
unreasonably withheld) and upon the reasonable request by the Trustee to the Company, a second firm of separate counsel) at any one time and the Company shall pay the reasonable fees and expenses of such counsel; provided, however,
that the Company will not be required to pay such fees and expenses if, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), it assumes the Trustee’s defense and there is no conflict of interest between
the Company, on the one hand, and the Trustee and its agents, employees, officers, stockholders and directors subject to the claim, on the other hand, in connection with such defense as reasonably determined by the Trustee. The Company need not pay
or indemnify for any settlement made without its written consent (which consent shall not be unreasonably withheld). The 

  
 -82-

 
Company need not reimburse any expense or indemnify against any loss, damage, claim, liability or expense to the extent caused by any negligence, bad faith or willful misconduct of the Trustee,
any predecessor Trustee, or any of their respective agents, employees, officers, stockholders or directors. 
 To secure the
Company’s payment obligations in this Section 7.07, the Trustee shall have a senior claim prior to the Notes against all money or property held or collected by the Trustee, in its capacity as Trustee, except funds held in trust for the
payment of principal of, or premium, if any, or interest on, or other amounts due under, the Notes or the Note Guarantees. 

When the Trustee incurs expenses or renders services after a Default specified in Section 6.01(7) occurs, such expenses and the
compensation for such services shall be paid to the extent allowed under any Bankruptcy Law. 
 Notwithstanding any other
provision in this Indenture, the foregoing provisions of this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the appointment of a successor Trustee. 
 SECTION 7.08. Replacement of Trustee. 
 The Trustee may resign at any time
by so notifying the Company in writing. The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee by so notifying the Company and the Trustee and may appoint a successor Trustee. The Company may remove the Trustee
if: 
 (1) the Trustee fails to comply with Section 7.10; 

(2) the Trustee is adjudged a bankrupt or an insolvent; 

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

(4) the Trustee becomes incapable of acting.

Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after
that, the retiring Trustee shall transfer, after payment of all sums then owing to the Trustee pursuant to Section 7.07, all property held by it as Trustee to the successor Trustee, subject to the Lien provided in Section 7.07, the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each
Noteholder. 

  
 -83-

  
 Subject to the
provisions of Section 7.09, no resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Section 7.08 shall become effective until the acceptance of appointment by the successor Trustee pursuant to
this Section 7.08. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Company.

 If the Trustee fails to comply with Section 7.10, any Noteholder may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding replacement of the Trustee pursuant to
this Section 7.08, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 

SECTION 7.09. Successor Trustee by Merger, Etc. 
 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, national association or other entity, the
resulting, surviving or transferee corporation, national association or other entity without any further act shall, if such resulting, surviving or transferee corporation, national association or other entity is otherwise eligible hereunder, be the
successor Trustee; provided that such corporation, national association or other entity shall be otherwise qualified and eligible under this Article Seven. 
 SECTION 7.10. Eligibility; Disqualification. 
 This Indenture shall always
have a Trustee who satisfies the requirement of TIA §§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of
condition. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of the bank holding company, shall meet the capital requirements of TIA § 310(a)(2). The Trustee shall comply
with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in
other securities, of the Company are outstanding, if the requirements for such exclusion set forth in TIA § 310(b)(1) are met. The provisions of TIA § 310 shall apply to the Company and any other obligor of the Notes. 

SECTION 7.11. Preferential Collection of Claims Against the Company. 
 The Trustee, in its capacity as Trustee hereunder, shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been
removed shall be subject to TIA § 311(a) to the extent indicated.

 ARTICLE EIGHT

 DISCHARGE OF INDENTURE; DEFEASANCE 
 SECTION 8.01. Termination of the Company’s Obligations. 
 This
Indenture will be discharged and will cease to be of further effect (except as provided in the second paragraph of this Section 8.01) as to all outstanding Notes when either: 

(1) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been
replaced or paid and Notes for whose payment U.S. Legal Tender has been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from this trust) have been delivered to the Trustee for
cancellation, or 
 (2) (a) all Notes not delivered to the Trustee for cancellation otherwise (i) have
become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to the redemption provisions of this Indenture and the Notes and, in any case, the
Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders, U.S. Legal Tender, U.S. Government Obligations or a combination thereof, in such amounts as will be
sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Indebtedness (including all principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation, 

(b) the Company has paid all other sums payable by it under this Indenture, 

(c) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of
the Notes at maturity or on the date of redemption, as the case may be, and 
 (d) the Company has delivered to
the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent providing for or relating to the termination of the Company’s obligations under the Notes and this Indenture have been complied
with. Such Opinion of Counsel shall also state that such satisfaction and discharge does not result in a default under the Senior Credit Agreement or any other indenture or agreement evidencing Indebtedness for money borrowed by the Company or any
of its Significant Subsidiaries in an outstanding principal amount of $50.0 million or more. 
 Subject to the next sentence and
notwithstanding the foregoing paragraph, the provisions of Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 4.03 (with respect to the existence of the Company only), 7.07, 8.04, 8.05 and 8.06 shall survive until the Notes have been cancelled or are no
longer outstanding pursuant to the last paragraph of Section 2.08. After the Notes are no 

  
 -85-

 
longer outstanding, the Company’s obligations in Sections 7.07, 8.05 and 8.06 shall survive such satisfaction and discharge. 

After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Company’s
obligations under the Notes and this Indenture except for those surviving obligations specified above. 
 SECTION 8.02. Legal Defeasance and
Covenant Defeasance. 
 (a) The Company may, at its option by Board Resolution of the Board of Directors of the Company, at
any time, elect to have either the Legal Defeasance option or the Covenant Defeasance option in paragraph (b) below be applied to all outstanding Notes upon compliance with the conditions set forth in Section 8.03. 

(b) Subject to Sections 8.02(c) and 8.03, the Company and the Subsidiary Guarantors at any time may terminate (i) all their
obligations under the Notes and this Indenture (“Legal Defeasance”), and after giving effect to such Legal Defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or
(ii) their obligations under Section 4.03 (other than with respect to the existence of the Company), Section 4.04 and Sections 4.09 through 4.19 and clause (3) of the first paragraph of Section 5.01, and the Company may omit
to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such 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 any omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Sections 6.01(4), (5), (6), (7) (with respect only to
Significant Subsidiaries), (8) and (9), the limitations contained in clause (3) of the first paragraph of Section 5.01, the failure of the Company to purchase Notes pursuant to Sections 4.09 or 4.15 and the events specified in
such Sections and clauses shall no longer constitute an Event of Default, but except as specified above in this clause (ii), the remainder of this Indenture and the Notes shall be unaffected thereby (clause (ii) being referred to as
“Covenant Defeasance”). The Company may exercise its Legal Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option. 
 If the Company exercises its Legal Defeasance option, payment of the Notes may not be accelerated because of an Event of Default and the Note Guarantees and all obligations of the Subsidiary Guarantors
under this Indenture shall terminate. If the Company exercises its Covenant Defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified under Sections 6.01(4), (5), (6), (7) (with respect only to
Significant Subsidiaries), (8) or (9) or because of failure to comply with clause (3) of the first paragraph of Section 5.01 or because of any failure to purchase Notes pursuant to Sections 4.09 or 4.15 and no failure by the
Company or any Subsidiary to comply with any of the foregoing Sections shall constitute a Default or Event of Default under this Indenture. 
 Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

 (c) Notwithstanding
the provisions of Sections 8.01(a) and (b), the provisions of Sections 2.02 through 2.11, 4.01 through 4.04, 4.06, 4.08, 6.07, 7.07 and 7.08 and in this Article Eight shall survive until the Notes have been surrendered to the Trustee for
cancellation and are no longer outstanding pursuant to the last paragraph of Section 2.08. After the Notes have been paid in full, the Company’s obligations under Sections 7.07, 8.04 and 8.05 shall survive. 

SECTION 8.03. Conditions to Legal Defeasance or Covenant Defeasance. 
 The following shall be the conditions to the application of either the Legal Defeasance option as the Covenant Defeasance option hereof to the outstanding Notes: 

In order to exercise either Legal Defeasance or Covenant Defeasance: 

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in
U.S. Legal Tender, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest
on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date; 

(2) in the case of an election of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel
(subject to customary exceptions and exclusions) reasonably acceptable to the Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this
Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such deposit and Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and Legal
Defeasance had not occurred; 
 (3) in the case of an election of Covenant Defeasance, the Company shall have
delivered to the Trustee an Opinion of Counsel (subject to customary exceptions and exclusions) reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default shall have occurred and be continuing either: (a) on the date of such deposit (other than a Default
resulting from the borrowing of funds to be applied to such deposit), or (b) insofar as Events of Default from bankruptcy or insolvency events pertaining to the Company are concerned, at any time in the period ending on the 91st day after the
date of deposit; provided that such Legal Defeasance or Covenant Defeasance, as the case may be, shall be deemed to have occurred on the date of such deposit, 

  
 -87-

 
subject to such Event of Default from bankruptcy or insolvency pertaining to the Company within such 91-day period; 

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default
under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; 

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

(7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all
conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with (which Opinion of Counsel may expressly assume that the only material agreements or instruments referred to in clause (5) of this
Section 8.03 are those listed in an Officers’ Certificate). 
 SECTION 8.04. Application of Trust Money. 

The Trustee or Paying Agent shall hold in trust U.S. Legal Tender and U.S. Government Obligations deposited with it pursuant to this
Article Eight and the principal and interest received in respect thereof, and shall apply the deposited U.S. Legal Tender and the money from U.S. Government Obligations in accordance with this Indenture to the payment of principal of and interest on
the Notes. The Trustee shall be under no obligation to invest said U.S. Legal Tender and U.S. Government Obligations except as it may agree with the Company. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Legal Tender and U.S. Government Obligations deposited pursuant to
Section 8.03 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. 

Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon
the Company’s request any U.S. Legal Tender and U.S. Government Obligations held by it as provided in Section 8.03 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 SECTION 8.05. Repayment to the Company. 
 Subject to this Article Eight,
the Trustee and the Paying Agent shall promptly pay to the Company upon request any excess U.S. Legal Tender and U.S. Government Obligations held by them at any time and thereupon shall be relieved from all liability with respect to such money. The
Trustee and the Paying Agent shall pay to the Company upon request any money 

  
 -88-

 
held by them for the payment of principal or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any payment, may
at the expense of the Company cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein
which shall be at least 30 days from the date of such publication or mailing any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to such money must look to the Company for
payment as general creditors unless an applicable law designates another Person. 
 SECTION 8.06. Reinstatement. 

If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender and U.S. Government Obligations deposited pursuant to
Section 8.01 or 8.03 in accordance with Section 8.04 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the
Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal
Tender and U.S. Government Obligations in accordance with this Article Eight; provided that if the Company has made any payment of premium, if any, or interest on or principal of any Notes because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the U.S. Legal Tender and U.S. Government Obligations held by the Trustee or Paying Agent. 

ARTICLE NINE

Notes (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes), may amend or supplement this Indenture, the Notes or the Note Guarantees, without notice to any other

other Noteholders. 

  
 -90-

  
 (b) Notwithstanding
Section 9.02(a), without the consent of each Holder of an outstanding Note affected, no amendment, supplement or waiver may:

 (d) After
an amendment, supplement or waiver under this Section 9.02(b) becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such
notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. 

  
 -91-

  
 SECTION 9.03. Intentionally
Omitted. 
 SECTION 9.04. Compliance with TIA. 
 Every amendment, waiver or supplement of this Indenture, the Notes or the Note Guarantees shall comply with the TIA as then in effect. 
 SECTION 9.05. Revocation and Effect of Consents. 
 Until an amendment,
waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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 or subsequent Holder may revoke the consent as to his Note or portion of his Note by notice to the Trustee and the Company received before the date on which such amendment, supplement
or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with the terms thereof (or if silent as to effectiveness, on the date on which the Trustee receives an Officers’ Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to such amendment, supplement or waiver) and thereafter binds every Holder. 

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver which record date shall be at least 30 days prior to the first solicitation of such consent. If a record date is fixed, then notwithstanding the second sentence of the immediately preceding paragraph, those Persons
who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent
shall be valid or effective for more than 90 days after such record date. The Company shall inform the Trustee in writing of the fixed record date if applicable. 
 After an amendment, supplement or waiver becomes effective, it shall bind every Noteholder. 

SECTION 9.06. Notation on or Exchange of Notes. 
 If an amendment, supplement or waiver changes the terms of a Note, the Company may require the Holder of the Note to deliver it to the Trustee. The Company shall provide the Trustee with an appropriate
notation on the Note about the changed terms and cause the Trustee to return it to the Holder at the Company’s expense. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 

  
 -92-

  
 SECTION 9.07. Trustee To Sign
Amendments, Etc. 
 The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine;
provided that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. The Trustee shall receive, and shall be
fully protected in conclusively relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and constituted the legal, valid and binding obligations of the Company enforceable in accordance with its terms (subject to customary exceptions). Such Opinion of Counsel shall be at the expense of the Company. 

ARTICLE TEN 

INTENTIONALLY OMITTED 
 ARTICLE ELEVEN 
 NOTE GUARANTEE 

SECTION 11.01. Unconditional Guarantee. 
 Subject to the provisions of this Article Eleven and to the fullest extent permitted by applicable law, each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably guarantees, on
a senior basis 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 Company or
any other Guarantors to the Holders or the Trustee hereunder or thereunder: (a) (x) the due and punctual payment of the principal of, premium, if any, and interest on the Notes when and as the same shall become due and payable, whether at
maturity, upon redemption or repurchase, by acceleration or otherwise, (y) the due and punctual payment of interest on the overdue principal and (to the fullest extent permitted by applicable law) overdue premium, if any, and interest, if any,
on the Notes and (z) the due and punctual payment and performance of all other obligations of the Company and all other obligations of the other Guarantors (including under the Note Guarantees), in each case, to the Holders or the Trustee
hereunder or thereunder (including amounts due the Trustee under Section 7.07 hereof), all in accordance with the terms hereof and thereof (collectively, the “Guarantee Obligations”); and (b) in case of any extension of
time of payment or renewal of any Notes or any of such other obligations, the due and punctual payment and performance of Guarantee Obligations in accordance with the terms of the extension or renewal, whether at maturity, upon redemption or
repurchase, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Company to the Holders under this Indenture or under the Notes, for whatever reason, each Guarantor
shall be obligated to pay, or to perform or cause the performance of, the same immediately. A Default under this Indenture or the Notes shall constitute an event of default under the 

  
 -93-

 
Note Guarantees, and shall entitle the Holders of Notes to accelerate the obligations of the Guarantors thereunder in the same manner and to the same extent as the obligations of the Company.

 Each of the Guarantors hereby agrees that (to the fullest extent permitted by law) its obligations hereunder shall be
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, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same, whether or not a Note Guarantee is affixed to any particular Note, or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a Guarantor. Each of the Guarantors hereby waives (to the fullest extent permitted by law) the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event
of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Note Guarantee shall not be discharged except by complete performance of the
obligations contained in the Notes, this Indenture and this Note Guarantee. This Note Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or governmental authority to return to the Company
or to any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or such Guarantor, any amount paid by the Company or such Guarantor to the Trustee or such Holder, this Note Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees (to the fullest extent permitted by law) that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand,
(a) subject to this Article Eleven, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and
payable by the Guarantors for the purpose of this Note Guarantee. 
 SECTION 11.02. Intentionally Omitted. 

SECTION 11.03. 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 Note 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 Note Guarantee. To effectuate the foregoing intention, the
Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Note Guarantee and this Article Eleven shall be limited to the maximum amount as will, after giving effect to all other contingent and
fixed liabilities of such Guarantor (including without limitation, any Guarantees under the Senior Credit Agreement and its Guarantees of the Existing Notes and the Notes of any other series) 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 Guarantor under its Note 

  
 -94-

 
Guarantee and this Article Eleven, result in the obligations of such Guarantor under its Note Guarantee and this Article Eleven not constituting a fraudulent transfer or conveyance under such
laws. 
 SECTION 11.04. Execution and Delivery of Note Guarantee. 

To further evidence its Note Guarantee set forth in Section 11.01, each Guarantor hereby agrees that a notation of such Note
Guarantee, substantially in the form of Exhibit C hereto, shall be endorsed on each Note authenticated and delivered by the Trustee. Such Note Guarantee shall be executed on behalf of each Guarantor by either manual or facsimile signature of
one Officer or other person duly authorized by all necessary corporate action of such Guarantor who shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Note Guarantee shall not be
affected by the fact that it is not affixed to any particular Note. 
 Each of the Guarantors hereby agrees that its Note
Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
 If an Officer of a Guarantor whose signature is on this Indenture or a Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such Note Guarantee is endorsed or
at any time thereafter, such Guarantor’s Note Guarantee of such Note shall nevertheless be valid. 
 The delivery of any
Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note Guarantee set forth in this Indenture on behalf of each Guarantor. 
 SECTION 11.05. Release of a Subsidiary Guarantor. 
 A Subsidiary Guarantor
shall be released from its obligations under its Note Guarantee and its obligations under this Indenture: 
 (1)
in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the equity interests of such Subsidiary
Guarantor then held by the Company and the Restricted Subsidiaries; 
 (2) if such Subsidiary Guarantor is
designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in each case in accordance with the provisions of this Indenture, upon effectiveness of such designation or when it first ceases to be a Restricted
Subsidiary, respectively; or 
 (3) if such Subsidiary Guarantor no longer Guarantees any other Indebtedness of
the Company or any Restricted Subsidiary of the Company (except for Guarantees of other Indebtedness of the Company or any Restricted Subsidiary of the Company that are released contemporaneously with the release of such Subsidiary Guarantor’s
Note 

  
 -95-

 
Guarantee); provided that a Subsidiary Guarantor shall not be permitted to be released from its Note Guarantee if it is an obligor with respect to Indebtedness that would not, under
Section 4.10, be permitted to be Incurred by a Restricted Subsidiary that is not a Subsidiary Guarantor. 
 The Trustee
shall execute an appropriate instrument prepared by the Company evidencing the release of a Subsidiary Guarantor from its obligations under its Note Guarantee upon receipt of a request by the Company or such Guarantor accompanied by an
Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 11.05; provided, however, that the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or
more Officers’ Certificates of the Company. 
 Except as set forth in Articles Four and Five and this Section 11.05,
nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety
or substantially as an entirety to the Company or another Guarantor. 
 SECTION 11.06. Waiver of Subrogation. 

Until this Indenture is discharged and all of the Notes are discharged and paid in full, each Guarantor hereby irrevocably waives and
agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Company’s obligations under the Notes or this Indenture and
such Guarantor’s obligations under this Note Guarantee and this Indenture, in any such instance including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in
any claim or remedy of the Holders against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or
indirectly, in cash or other assets or by set off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the
Trustee or the Holders of Notes under the Notes or this Indenture, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the
Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with
the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.06 is knowingly made in
contemplation of such benefits. 
 SECTION 11.07. Immediate Payment. 

Each Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all Guarantee Obligations owing or payable to
the respective Holders upon receipt of a demand for payment therefor by the Trustee to such Guarantor in writing. 

  
 -96-

  
 SECTION 11.08. No Set Off.

 Each payment to be made by a Guarantor hereunder in respect of the Guarantee Obligations shall be payable in the currency or
currencies in which such Guarantee Obligations are denominated, and shall be made without set off, counterclaim, reduction or diminution of any kind or nature. 
 SECTION 11.09. Guarantee Obligations Absolute. 
 The obligations of each
Guarantor hereunder are and shall be absolute and unconditional and any monies or amounts expressed to be owing or payable by each Guarantor hereunder which may not be recoverable from such Guarantor on the basis of a Guarantee shall be recoverable
from such Guarantor as a primary obligor and principal debtor in respect thereof. 
 SECTION 11.10. Guarantee Obligations Continuing.

 The obligations of each Guarantor hereunder shall be continuing and shall remain in full force and effect until all such
obligations have been paid and satisfied in full. Each Guarantor agrees with the Trustee that, to the fullest extent permitted by applicable law, it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability
hereunder and under any other instrument or instruments in such form as counsel to the Trustee may reasonably request and as will prevent any action brought against it in respect of any default hereunder being barred by any statute of limitations
now or hereafter in force and, in the event of the failure of a Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or
other instruments as may from time to time become necessary or reasonably advisable, in the judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such Guarantor hereunder. 

SECTION 11.11. Guarantee Obligations Not Reduced. 
 Subject to Section 11.05, the obligations of each Guarantor hereunder shall not be satisfied, reduced or discharged solely by the payment of such principal, premium, if any, interest, fees and other
monies or amounts as may at any time prior to discharge of this Indenture pursuant to Article Eight be or become owing or payable under or by virtue of or otherwise in connection with the Notes or this Indenture. 

SECTION 11.12. Guarantee Obligations Reinstated. 
 Subject to Section 11.05, to the fullest extent permitted by applicable law, the obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if
at any time any payment which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from any of
the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or any Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Company or any
other Guarantor is stayed upon the insolvency, 

  
 -97-

 
bankruptcy, liquidation or reorganization of the Company or such Guarantor, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each
Guarantor as provided herein. 
 SECTION 11.13. Guarantee Obligations Not Affected. 

Subject to Section 11.05, to the fullest extent permitted by applicable law, the obligations of each Guarantor hereunder shall not
be affected, impaired or diminished in any way by any act, omission, matter or thing whatsoever, occurring before, upon or after any demand for payment hereunder (and whether or not known or consented to by any Guarantor or any of the Holders)
which, but for this provision, might constitute a whole or partial defense to a claim against any Guarantor hereunder or might operate to release or otherwise exonerate any Guarantor from any of its obligations hereunder or otherwise affect such
obligations, whether occasioned by default of any of the Holders or otherwise, including, without limitation: 

(a) any limitation of status or power, disability, incapacity or other circumstance relating to the Company or any other
Person, including any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, winding-up or other proceeding involving or affecting the Company or any other Person; 

(b) any irregularity, defect, unenforceability or invalidity in respect of any indebtedness or other obligation of the
Company or any other Person under this Indenture, the Notes or any other document or instrument; 
 (c) any
failure of the Company or any other Guarantor, whether or not without fault on its part, to perform or comply with any of the provisions of this Indenture, the Notes or any Note Guarantee, or to give notice thereof to a Guarantor; 

(d) the taking or enforcing or exercising or the refusal or neglect to take or enforce or exercise any right or remedy
from or against the Company or any other Person or their respective assets or the release or discharge of any such right or remedy; 
 (e) the granting of time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Company or any other Person;

 6 3/8% Senior Notes due 2018 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

 SECTION 1. Interest. DaVita Inc., a Delaware corporation (the “Company”),
promises to pay interest on the principal amount of this Note at 6 3/8% per annum from October 20, 2010 until maturity. The Company will pay interest semi-annually in arrears on May 1 and November 1 of each year (each an “Interest Payment
Date”), or if any such day is not a Business Day, on the next succeeding Business Day, commencing May 1, 2011. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been
paid, from the Issue Date; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and, to the fullest extent permitted by
applicable law, overdue premium, if any, and overdue installments of interest, without regard to any applicable grace periods, at the rate of 2.0% per annum in excess of the interest rate otherwise applicable to the Notes from time to time.
Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 SECTION 2. Method of Payment.
The Company will pay interest on the Notes to the Persons who are Holders of Notes at the close of business on the April 15 or October 15, as the case may be, 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 will be issued in denominations of $2,000 and integral multiples of $1,000 in excess
thereof. The Company shall pay principal, premium, if any, and interest on the Notes in U.S. Legal Tender. Principal, premium, if any, and interest on the Notes will be payable at the office or agency of the Company maintained for such purpose or,
at the option of the Company, payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the register of Holders of Notes; provided that all payments of principal, premium, if any,
and interest with respect to Notes in global form registered in the name of or held by the Depository or its nominee shall be paid in immediately available funds to DTC or its nominee, as the case may be. Until otherwise designated by the Company,
the Company’s office or agency in New York will be the office of the Trustee maintained for such purpose. 
 SECTION 3.
Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any
Holder. The Company or any of its Restricted Subsidiaries may act in any such capacity. 
 SECTION 4. Indenture. The
Company issued the Notes under an Indenture dated as of October 20, 2010, as amended or supplemented (“Indenture”), by and among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the

  
 A-4

 
Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). The
Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA 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. 
 SECTION 5. Optional Redemption. Except as described below, the Notes are
not redeemable at the Company’s option until November 1, 2013. On and after November 1, 2013, the Company may at its option redeem the Notes, in whole or from time to time in part, upon not less than 30 nor more than 60 days’
notice, at the following Redemption Prices (expressed as a percentage of principal amount) plus accrued and unpaid interest, if any, on the Notes to be redeemed to the applicable Redemption Date, if redeemed during the twelve-month period
beginning on November 1 of the years indicated below: 
  

					
	 Year
	  	Percentage	 
	 2013
	  	 	104.781	% 
	 2014
	  	 	103.188	% 
	 2015
	  	 	101.594	% 
	 2016 and thereafter
	  	 	100.000	% 

 SECTION 6. From and after
the Issue Date, prior to November 1, 2013, the Company may, at its option, on any one or more occasions, upon not less than 30 nor more than 60 days notice, redeem up to 35% of the original aggregate principal amount of Notes (including the
original aggregate principal amount of any Additional Notes) issued under the Indenture with the Net Cash Proceeds of one or more Equity Offerings at a Redemption Price (expressed as a percentage of the principal amount thereof) of 106.375%
plus accrued and unpaid interest, if any, to the Redemption Date; provided that 
  

	 	(1)	at least 65% of the original aggregate principal amount of the Notes (including the original aggregate principal amount of any Additional Notes) issued under the
Indenture remains outstanding after each such redemption; and 

  

	 	(2)	the redemption date occurs within 90 days after the closing of such Equity Offering (for purposes of clarity, in the event that there are two or more closings for any
Equity Offering, then each such closing shall be deemed a separate “closing” for purposes of the foregoing provisions of this clause (2) with respect to the securities issued at such closing). 

In addition, the Notes may be redeemed, in whole or from time to time in part, at any time prior to November 1, 2013, at the
Company’s option, upon not less than 30 nor more than 60 days’ notice, at a Redemption Price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium on those Notes as of, and accrued and unpaid interest, if
any, on those Notes to, the applicable Redemption Date. 
 SECTION 7. Notice of Redemption. Notice of redemption will be
mailed by first class mail at least 30 days but not more than 60 days before the redemption date to each 

  
 A-5

 
Holder of Notes to be redeemed at its registered address. Notes may be redeemed in part only in integral multiples of $1,000 and the remaining principal amount of any Note must not be less than
$2,000. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the redemption date, interest ceases to accrue on Notes or portions thereof called for redemption. 

SECTION 8. Mandatory Redemption. For the avoidance of doubt, an offer to purchase pursuant to Section 9 hereof shall not be
deemed a redemption. The Company shall not be required to make mandatory redemption payments or sinking fund payments with respect to the Notes. 
 SECTION 9. Repurchase at Option of Holder. Upon the occurrence of a Change of Control, and subject to certain conditions set forth in the Indenture, each Holder will have the right to require the
Company to purchase all or any part (in integral multiples of $1,000, provided that the remaining principal amount of any Note repurchased in part must not be less than $2,000) of such Holder’s Notes at a purchase price in cash equal to 101% of
the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the Change of Control Payment Date. 

SECTION 10. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000
and integral multiples of $1,000. 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 Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company and the Registrar are not required to transfer or exchange any Note selected for redemption in whole or in
part, except the unredeemed portion of any Note being redeemed in part, or during a Change of Control Offer or an Asset Disposition Offer if such Note is validly tendered pursuant to such Change of Control Offer or Asset Disposition Offer and not
validly withdrawn. Also, the Company and the Registrar are not required to transfer or exchange any Notes for a period beginning at the opening of business 15 days before the mailing of a notice of redemption and ending at the close of business on
the day of such mailing or register the transfer or exchange of any Note selected for redemption in whole or in part except the unredeemed portion of any Note redeemed in part. 

SECTION 11. Persons Deemed Owners. The Holder of a Note may be treated as its owner for all purposes. 

SECTION 12. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Notes and the Note Guarantees may
be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or Event of Default and its consequences or compliance with any provision
hereof or thereof may be waived with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture, the
Notes and the Note Guarantees to, among other things, cure any ambiguity, omission, defect or 

  
 A-6

 
inconsistency, provide for uncertificated Notes in addition to certificated Notes, comply with any requirements of the SEC in connection with the qualification of the Indenture under the TIA, or
make any change that does not materially adversely affect the rights of any Holder of a Note. 
 SECTION 13. Defaults and
Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes generally may declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency as set forth in the Indenture, with respect to the Company, all outstanding Notes will become due and payable without further action or notice.
Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium or interest) if it determines that withholding notice is in their interest.

 SECTION 14. Restrictive Covenants. The Indenture contains certain covenants that, among other things, limit the
ability of the Company and its Restricted Subsidiaries to make restricted payments, to incur indebtedness, to create liens, to sell assets, to permit restrictions on dividends and certain other payments by Restricted Subsidiaries of the Company, to
consolidate, merge or sell all or substantially all of its assets or to engage in transactions with affiliates. Certain of the restrictive covenants will not be applicable to the Company and its Restricted Subsidiaries during any period that the
Notes receive an Investment Grade Rating by both Rating Agencies and certain other conditions are satisfied. The covenants are subject to a number of important qualifications and exceptions. The Company must annually report to the Trustee on
compliance with such covenants. 
 SECTION 15. No Recourse Against Others. No director, officer, employee, incorporator,
stockholder, partner or member of, or owner of any equity interest in, the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Note Guarantees or for
any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

 SECTION 16. Note Guarantees. This Note will be entitled to the benefits of certain Note Guarantees made for the
benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors, the Trustee and the Holders. 

SECTION 17. Trustee Dealings with the Company. Subject to certain limitations specified in the TIA, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company, its Subsidiaries or their respective Affiliates with the same rights it would have if it were not the Trustee.

tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
 SECTION 20. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes
and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

governed by and construed in accordance with the laws of the State of New York, as applied to contracts made and performed within the State of New York, without regard to principles of conflicts of laws.
