SBA COMMUNICATIONS CORPORATION 

 
 2018 EMPLOYEE STOCK PURCHASE PLAN 

This SBA Communications Corporation 2018 Employee Stock Purchase Plan (the “Plan”) is effective as of the Effective
Date. 
 1. Purpose and Structure of the Plan and its Sub-Plans. 

1.1 The purpose of this Plan is (a) to provide eligible employees of the Company and Participating Companies who wish to become shareholders in the
Company a convenient method of doing so, (b) to encourage employees to work in the best interests of shareholders of the Company, (c) to support recruitment and retention of qualified employees, and (d) to provide employees an
advantageous means of accumulating long-term investments. It is believed that employee participation in the ownership of the business will be to the mutual benefit of both the employees and the Company. This Plan document is an omnibus document
which includes a sub-plan (“Statutory Plan”) designed to permit offerings of grants to employees of certain Subsidiaries that are Participating Companies where such offerings are intended to
satisfy the requirements of Section 423 of the Code (although the Company makes no undertaking nor representation to obtain or maintain qualification under Section 423 for any Subsidiary, individual, offering or grant) and also separate sub-plans (“Non-Statutory Plans”) which permit offerings of grants to employees of certain Participating Companies which are not intended to satisfy the
requirements of Section 423 of the Code. Section 6 of the Plan sets forth the maximum number of shares to be offered under the Plan (and its sub-plans), subject to adjustments as permitted under
Sections 18 and 19. 
 1.2 The Statutory Plan shall be a separate and independent plan from the Non-Statutory Plans,
provided, however, that the total number of shares authorized to be issued under the Plan applies in the aggregate to both the Statutory Plan and the Non-Statutory Plans. Offerings under the Non-Statutory Plans may be made to achieve desired tax or other objectives in particular locations outside the United States of America or to comply with local laws applicable to offerings in such foreign
jurisdictions. Offerings under the Non-Statutory Plans may also be made to employees of entities that are not Subsidiaries. 

1.3 All employees who participate in the Statutory Plan shall have the same rights and privileges under such sub-plan
except for differences that may be mandated by local law and are consistent with the requirements of Code Section 423(b)(5). The terms of the Statutory Plan shall be those set forth in this Plan document to the extent such terms are consistent
with the requirements for qualification under Code Section 423. The Administrator may adopt Non-Statutory Plans applicable to particular Participating Companies or locations that are not participating in
the Statutory Plan. The terms of each Non-Statutory Plan may take precedence over other provisions in this document, with the exception of Sections 6, 18 and 19 with respect to the total number of shares
available to be offered under the Plan for all sub-plans. Unless otherwise superseded by the terms of such Non-Statutory Plan, the provisions of this Plan document shall
govern the operation of such Non-Statutory Plan. Except to the extent expressly set forth herein or where the context suggests otherwise, any reference herein to “Plan” shall be construed to include
a reference to the Statutory Plan and the Non-Statutory Plans. 
 2. Definitions. 

2.1 “Account” means the funds accumulated with respect to an individual employee as a result of deductions from such employee’s paycheck
or lump sum payments made by such employee (or

Account shall be deposited in the Company’s general corporate accounts and may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate or otherwise set apart such funds allocated to an
employee’s Account from any other corporate funds, except to the extent such commingling may be prohibited by the laws of any applicable jurisdiction.

consolidation; provided, however, that a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no Person acquires more than 25% of the combined voting power of the Company’s then
outstanding securities shall not constitute a Change in Control;

whether they are also citizens of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) shall not be eligible to participate in the Statutory Plan if: (i) the grant of an option under the Plan to
such employee is prohibited under the laws of such jurisdiction; or (ii) compliance with the laws of such foreign jurisdiction would cause the Statutory Plan to violate the requirements of Section 423 of the Code. During leaves of absence

 4. Offerings. Subject to the right of the Company in its sole discretion to sooner terminate the
Plan or to change the commencement date or term of any offering, commencing June 1, 2018, the Plan will operate with separate consecutive quarterly offerings with the following Purchase Dates: May 31, August 31, November 30 and
February 28 (February 29 in leap years). The initial offering period shall start June 1, 2018 and end August 31, 2018. In order to become eligible to purchase shares, an employee must complete and submit an Enrollment Agreement and
any other necessary documents before the Offering Date of the particular offering in which he or she wishes to participate. Participation in one offering under the Plan shall neither limit, nor require, participation in any other offering.
Notwithstanding the foregoing, the Committee may establish (i) a different term for one or more future offerings and (ii) different commencing and ending dates for such offerings; provided, however, that in no event shall any offering
exceed 27 months. In the event the first or the last day of an offering is not a regular business day, then the first day of the offering shall be deemed to be the next regular business day and the last day of the offering shall be deemed to be the
last preceding regular business day. 
 5. Price. The Purchase Price per share shall be eighty-five percent (85%) of the Fair Market Value of
the Class A Common Stock on the Purchase Date of such offering (the “Applicable Discount Price”). 
 6. Number of Shares to
be Offered. The maximum number of shares that will be offered under the Plan is 300,000 shares, subject to adjustment as permitted under Section 19. The shares to be sold to participants under the Plan will be Class A Common
Stock of the Company. If the total number of shares for which options are to be granted on any date in accordance with Section 11 exceeds the number of shares then available under the Plan or a given
sub-plan (after deduction of all shares for which options have been exercised under the Plan or are then outstanding), the Company shall make a pro rata allocation of the shares remaining available in as
nearly a uniform manner as it determines is practicable and equitable. In such event, (a) the payroll deductions to be made pursuant to the authorizations therefor shall be reduced accordingly and the Company shall give written notice of the
reduction to each employee affected and (b) any portion of lump sum payments made but not used to purchase shares shall be returned accordingly. Any shares of Class A Common Stock delivered under the Plan may consist, in whole or in part,
of authorized and unissued shares or treasury shares. 
 7. Participation. 

7.1 An eligible employee may become a participant by completing an Enrollment Agreement provided by the Company and submitting it to the Company, or with such
other entity designated by the Company for this purpose, prior to the commencement of the offering to which it relates. The Enrollment Agreement may be completed at any time after the employee becomes eligible to participate in the Plan, and will be
effective as of the Offering Date next following the receipt of a properly completed Enrollment Agreement by the Company (or the Company’s designee for this purpose). 

7.2 An eligible employee may elect to participate in the Plan by way of payroll deductions or lump sum payments for the relevant offering period in accordance
with Section 8. 
 7.3 The Company may require current participants to complete a new Enrollment Agreement at any time it deems necessary or desirable
to facilitate Plan administration or for any other reason. 
 7.4 The Committee may provide, in its discretion, for automatic
re-enrollment such that, at the termination of each offering, each participating employee who continues to be eligible to participate pursuant to Section 3 would be automatically re-enrolled in the next offering, unless the employee has advised the Company otherwise. 

  
 5 

 8. Payroll Deductions and Lump Sum Payments. 

8.1 Payroll Deductions. 
 (a) Unless the
eligible employee has elected to participate in the Plan under Section 8.2, an eligible employee may elect to participate in the Plan by means of payroll deductions prior to the relevant offering period by delivering to the Company, no later
than the close of business on the fifth (5th) business day prior to the commencement of such offering period, a payroll deduction authorization Notice. At the time an employee files a payroll
deduction authorization Notice, the employee shall elect to have deductions made from the employee’s Compensation on each payday during each calendar year, which shall be a flat amount, a percentage or a combination of both, and be equal to
(i) at least 1% of the participant’s Compensation as of the Offering Date and (ii) at least twenty-five dollars ($25.00) per pay period, subject to the limitations set forth in Section 8.3 and the other restrictions set forth in
the Plan. The amount of payroll withholding for each participant for each pay period shall be generally determined by dividing the annual payroll withholding amount chosen by each participant by the total number of pay periods such participant has
in such calendar year, subject to the discretion of the Committee. The Committee may, from time to time, establish (x) limitations on the frequency and/or number of any permitted changes in the amount withheld during an offering,
(y) payroll withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, and (z) such other limitations or
procedures as deemed advisable by the Committee in the Committee’s sole discretion that are consistent with the Plan and in accordance with the requirements of Code Section 423. 

(b) All payroll deductions made for a participant shall be credited to his or her Account under the Plan. 

(c) A participant may make a change in his or her participation in the Plan as provided in Section 9. 

(d) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code, Section 20 hereof, or any
other applicable law, a participant’s payroll deductions may be decreased, including to zero, at such time during any offering which is scheduled to end during the current calendar year that the aggregate of all payroll deductions accumulated
with respect to such offering and any other offering ending within the same calendar year equal or exceed the limitation on such amounts as set forth in Section 8.3. Payroll deductions shall recommence at the rate provided in the
participant’s Enrollment Agreement at the beginning of the following offering which is scheduled to end in the following calendar year, unless the participant withdraws from an offering or the Plan, pursuant to Section 9. 

8.2 Lump Sum Payments. 
 (a) Unless the
eligible employee has elected to participate in the Plan under Section 8.1, an eligible employee may elect to participate in the Plan for an offering period by delivering to the Company, no later than the close of business on the fifth (5th) business day prior to the commencement of such offering period, a Notice of election to participate in the Plan by lump sum payment. Lump sum payments remitted by the participant shall be a flat
amount and shall be subject to the limitations set forth in Section 8.3 and the other restrictions set forth in the Plan. 

  
 6 

 (b) All lump sum payments remitted by a participant shall be credited to his or her Account under
the Plan. Lump sum payments remitted by a participant must be remitted in current funds no later than two (2) weeks prior to the end of the applicable offering period. 

(c) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code, Section 20 hereof, or any
other applicable law, a participant’s lump sum payment or a portion thereof may be returned at such time during any offering which is scheduled to end during the current calendar year that the aggregate of all contributions (whether by payroll
deduction or lump sum payment) accumulated with respect to such offering and any other offering ending within the same calendar year equal or exceed the limitation on such amounts as set forth in Section 8.3. 

8.3 Limitations on Purchase. No employee shall be granted an option under the Statutory Plan which permits his or her rights to purchase shares
under the Plan and all other “employee stock purchase plans” of the Company and its Subsidiaries to accrue at a rate that exceeds $25,000 of Fair Market Value of such shares (determined at the time such option is granted) for each calendar
year in which the option is outstanding at any time. Notwithstanding the above, different limitations may be imposed with respect to participants in a Non-Statutory Plan or participants in the Statutory Plan
who are subject to laws of another jurisdiction where lower limitations are required. 
 9. Change in Participation. 

9.1 Decrease of Contribution or Discontinued Participation. A participant may discontinue his or her participation in the Plan as provided in
Section 17, or may decrease his or her payroll deductions or lump sum payment at any time during an offering period, by delivering to the Company a new Notice authorizing a reduction in the amount of payroll deductions or lump sum amount, as
the case may be. 
 9.2 Increase of Contribution. A participant may not increase the amount of his or her payroll deductions or lump sum
contributions once the offering period has commenced. 
 9.3 Miscellaneous. The Administrator shall have the authority to modify the rules and
regulations regarding changes in participation, by providing participants notice of such change at least 15 days prior to the Offering Date. 
 10.
Interest. No interest will be paid or allowed on any money in the Accounts of participating employees, except to the extent payment of interest is required by the laws of any applicable jurisdiction. 

11. Granting of Option. On each Offering Date, this Plan shall be deemed to have granted to the participant an option to purchase, at the
Purchase Price, the largest number of whole shares of Class A Common Stock as does not exceed the number of shares determined by dividing $25,000 by the Fair Market Value of a share of Class A Common Stock on the Offering Date, subject to
the limitations set forth in Section 8.3. 
 12. Exercise of Option. 

12.1 Each employee who continues to be a participant in an offering on the last business day of that offering shall be deemed to have exercised his or her
option on that date and shall be deemed to have purchased from the Company, at the Purchase Price, the number of whole shares of Class A Common Stock reserved for the purpose of the Plan as the balance of his or her Account on such date will
pay for. 

  
 7 

 12.2 Any cash balance remaining in a participant’s Account at the termination of an offering (after exercise
of his or her option) shall, at the election of the Company, be either carried over in the participant’s Account and applied to the purchase of Class A Common Stock in the next offering, provided the participant participates in the next
offering and the purchase complies with Section 20, or refunded to the participant. 
 13. Tax Obligations. To the extent any
(i) grant of an option to purchase shares, (ii) purchase of shares, or (iii) disposition of shares purchased under the Plan gives rise to any tax withholding obligation (including, without limitation, income and payroll withholding
taxes imposed by any jurisdiction), the Administrator may implement appropriate procedures to ensure that such tax withholding obligations are met. Those procedures may include, without limitation, increased withholding from an employee’s
current compensation, cash payments to the Company or another Participating Company by an employee, or a sale of a portion of the Class A Common Stock purchased under the Plan, which sale may be required and initiated by the Company. 

14. Employee’s Rights as a Shareholder. No participating employee shall have any right as a shareholder with respect to any shares until
the shares have been purchased in accordance with Section 12 above and the Class A Common Stock has been issued by the Company. 
 15. Evidence
of Stock Ownership. 
 15.1 Following the end of each offering, the number of shares of Class A Common Stock purchased by each participant shall be
deposited into an account established in the participant’s name at the ESPP Broker. 
 15.2 A participant shall be free to undertake a disposition (as
that term is defined in Section 424(c) of the Code) of the shares in his or her ESPP Broker account at any time, whether by sale, exchange, gift, or other transfer of legal title, but in the absence of such a disposition of the shares, the
shares must remain in the participant’s ESPP Broker account until the holding period set forth in Section 423(a) of the Code has been satisfied. With respect to shares for which the Section 423(a) holding period has been satisfied,
the participant may move those shares to another brokerage account of participant’s choosing. 
 15.3 Notwithstanding the above, a participant who is
not subject to income taxation under the Code may move his or her shares to another brokerage account of his or her choosing at any time, without regard to the satisfaction of the Section 423(a) holding period. 

16. Rights Not Transferable. No employee shall be permitted to sell, assign, transfer, pledge, or otherwise dispose of or encumber either the
payroll deductions or lump sum payments credited to his or her Account or an option or any rights with regard to the exercise of an option or rights to receive shares under the Plan other than by will or the laws of descent and distribution, and
such right and interest shall not be liable for, or subject to, the debts, contracts, or liabilities of the employee. If any such action is taken by the employee, or any claim is asserted by any other party in respect of such right and interest
whether by garnishment, levy, attachment or otherwise, the action or claim will be treated as an election to withdraw funds in accordance with Section 17. During the employee’s lifetime, only the employee can make decisions regarding the
participation in or withdrawal from an offering under the Plan. 

  
 8 

 17. Termination of Participation or Transfer of Employment. 

17.1 Early Termination of Participation; Voluntary Withdrawal. 

(a) A participant may terminate his or her obligation to make any additional payments into the Plan, either by additional payroll deductions
or by additional lump sum payments, at any time during an offering period by delivering a Notice of such early termination to the Company. Upon delivery of such Notice, all payroll deductions will cease and/or the participant will be relieved from
any future lump sum payment obligations, as applicable. Upon any such early termination, such participant may elect either to withdraw from the Plan pursuant to Section 17.1(b) below or to have amounts credited to his or her Account for the
purchase of Class A Common Stock pursuant to Section 12. A participant who early terminates his or her participation in the Plan during any offering period shall not be permitted to resume making contributions, or remitting lump sum
payments, as applicable, to the Plan during such offering period. 
 (b) A participant may withdraw from the Plan at any time by delivering
a Notice to the Company prior to the close of business on a Purchase Date. Within 21 days after the Notice of withdrawal is delivered, the Company shall refund the entire amount, if any, in a participant’s Plan Account to him or her, and the
following shall be deemed automatically terminated: (i) the participant’s Notice authorizing payroll deduction or electing to participate in the Plan by remitting a lump sum payment, as applicable, (ii) his or her interest in the Plan
and (iii) his or her option under the Plan. Any eligible employee who withdraws from the Plan may again become a participant in accordance with Sections 7 and 8. 

17.2 Termination of Employment. Upon termination of employment for any reason whatsoever, including but not limited to death or retirement, the
balance in the Account of a participating employee shall be paid to the employee or his or her estate. Whether and when employment is deemed terminated for purposes of this Plan shall be determined by the Administrator in its sole discretion and may
be determined without regard to statutory notice periods or other periods following termination of active employment. 
 17.3 Transfer of Employment.

 (a) In the event that a participant who is an employee of a Participating Company in a
Non-Statutory Plan is transferred and becomes an employee of a different Participating Company in a Non-Statutory Plan, during an offering, such individual may, subject
to the terms and eligibility of the Non-Statutory Plan of the new employer, become a participant under the Non-Statutory Plan of the new employer for the duration of the
offering in effect at that time. Unless otherwise required under local law, any payroll deductions, lump sum payments or other approved contributions may continue to be held by the Participating Company former employer of the participant for the
remainder of the offering. At the next Purchase Date, all payroll deductions and other approved contributions made by or to such Participating Company former employer and/or the employer Participating Company shall be aggregated for the purchase of
shares of Class A Common Stock under, and subject to the terms and limitations of, the Non-Statutory Plan of the new employer. 

(b) In the event that an employee of a Participating Company in the Statutory Plan and who is a participant in the Statutory Plan is
transferred and becomes an employee of a Participating Company in a Non-Statutory Plan during an offering, such individual may, subject to the terms and eligibility of the
Non-Statutory Plan of the new employer, become a participant under the 

  
 9 

 
Non-Statutory Plan of the new employer for the duration of the offering in effect at that time. Unless otherwise required under local law, any payroll
deductions or lump sum payments may continue to be held by the Participating Company former employer for the remainder of the offering. At the next Purchase Date, all payroll deductions and other approved contributions made by or to the
Participating Company former employer and/or the employer Participating Company may be aggregated for the purchase of shares of Class A Common Stock under, and subject to the terms and limitations of, the
Non-Statutory Plan of the new employer. 
 18. Amendment or Discontinuance of the Plan. 

18.1 The Board may amend the Plan in such respects as it shall deem advisable; provided, however, that, to the extent required for compliance with Code
Section 423 or any applicable law or regulation, shareholder approval will be required for any amendment that will (i) increase the total number of shares as to which options may be granted under the Plan, except as provided in
Section 19, (ii) modify the class of employees eligible to receive options, or (iii) otherwise require shareholder approval under any applicable law or regulation; and provided further, that except as provided in this Section 18,
no amendment to the Plan shall make any change in any option previously granted which adversely affects the rights of any participant. 
 18.2 The Plan
shall become effective upon approval by the Company’s shareholders in accordance with the Company’s Articles of Incorporation and Bylaws and applicable state law and stock exchange rules (the “Effective Date”), and shall
continue in effect for ten years after the Effective Date. If shareholder approval is not obtained, then this Plan and any grants made hereunder, shall immediately terminate and be null and void. Notwithstanding the foregoing, the Board may at any
time and for any reason suspend or terminate the Plan. During any period of suspension or upon termination of the Plan, no options shall be granted. 
 18.3
Except as provided in Section 19, no such termination of the Plan may affect options previously granted, provided that the Plan or an offering may be terminated by the Board on a Purchase Date or by the Board’s setting a new Purchase Date
with respect to an offering then in progress if the Board determines that termination of the Plan and/or the offering is in the best interests of the Company and the shareholders or if continuation of the Plan and/or the offering would cause the
Company to incur adverse accounting charges as a result of a change after the Effective Date in the generally accepted accounting principles applicable to the Plan. 

19. Changes in Capitalization. In the event of reorganization, recapitalization, stock split, stock dividend, combination of shares, merger,
consolidation, offerings of rights, or any other change in the structure of the Class A Common Stock of the Company, the Committee shall make such adjustment, if any, as it may deem appropriate in the number, kind, and the price of shares
available for purchase under the Plan, and in the number of shares which an employee is entitled to purchase including, without limitation, closing an offering early and permitting purchase on the last business day of the reduced offering period, or
terminating an offering and refunding participants’ Account balances. 
 20. Share Ownership. Notwithstanding anything in the Plan to the
contrary, no employee shall be permitted to participate in the Plan if the employee, immediately after the applicable Purchase Date, owns shares (including all shares that may be purchased under outstanding options under the Plan) possessing 5% or
more of the total combined voting power or value of all classes of shares of the capital stock of the Company or any Subsidiary. For the foregoing purposes, the rules of Section 424(d) of the Code shall apply in determining share ownership, and
shares the employee may purchase under outstanding options shall be treated as owned by the employee. 

  
 10 

 21. Administration and Authority. 

21.1 The Plan shall be administered by the Committee. The Committee may delegate any or all of its authority under this Plan to such senior officer(s) of the
Company as it may designate, to the extent not prohibited by law or rules of Nasdaq. The authority that may be delegated by the Committee includes, without limitation, the authority to (i) establish
Non-Statutory Plans and determine the terms of such sub-plans (including, without limitation, rules and procedures regarding handling of payroll deductions or other
approved contributions, payment of interest, conversion of local currency, payroll tax, withholding procedures and handling of stock certificates that vary with local requirements and determining the eligible employees that may enroll in a Non-Statutory Plan), (ii) designate from time to time which Subsidiaries will participate in the Statutory Plan, which Subsidiaries and Affiliates will be Participating Companies, and which Participating Companies
will participate in a particular Non-Statutory Plan, (iii) determine procedures for eligible employees to enroll in or withdraw from a sub-plan, setting or changing
payroll deduction amounts, and obtaining necessary tax withholdings, (iv) allocate the available shares under the Plan to the sub-plans for particular offerings, and (v) adopt amendments to the Plan
or any sub-plan including, without limitation, amendments to increase the shares available for issuance under the Plan pursuant to Section 19 (but not including increases in the available shares above the
maximum permitted by Sections 6 and 19 which shall require Board and shareholder approval). 
 21.2 The Administrator shall be vested with full authority
and discretion to construe the terms of the Plan and make factual determinations under the Plan, and to make, administer, and interpret such rules and regulations as it deems necessary to administer the Plan, and any determination, decision, or
action of the Administrator in connection with the construction, interpretation, administration, or application of the Plan shall be final, conclusive, and binding upon all participants and any and all persons claiming under or through any
participant. The Administrator may retain outside entities and professionals to assist in the administration of the Plan including, without limitation, a vendor or vendors to perform enrollment and brokerage services. The authority of the
Administrator will specifically include, without limitation, the power to make any changes to the Plan with respect to the participation of employees of any Subsidiary or Affiliate that is organized under the laws of a country other than the United
States of America when the Administrator deems such changes to be necessary or appropriate to achieve a desired tax treatment in such foreign jurisdiction or to comply with the laws applicable to such non-U.S.
Subsidiaries or Affiliates. Those changes may include, without limitation, the exclusion of particular Subsidiaries or Affiliates from participation in the Plan, modifications to eligibility criteria, maximum number or value of shares that may be
purchased in a given period, or other requirements set forth herein; and procedural or administrative modifications. Any modification relating to offerings to a particular Participating Company will apply only to that Participating Company, and will
apply equally to all similarly situated employees of that Participating Company. The rights and privileges of all employees granted options under the Statutory Plan shall be the same. To the extent any changes approved by the Administrator would
jeopardize the tax-qualified status of the Statutory Plan, the change shall cause the Participating Companies affected thereby to be considered Participating Companies under a
Non-Statutory Plan or Non- Statutory Plans instead of the Statutory Plan. 

21.3 Notwithstanding the provisions of Sections 21.1 and 21.2 above, in the event that Rule 16b-3 promulgated under
the Exchange Act or any successor provision thereto (“Rule 16b-3”) provides specific requirements for the administrators of plans of this type, the Plan shall only be administered by such body
and in such a manner as shall comply with the applicable requirements of Rule 16b-3. Unless permitted by Rule 16b-3, no discretion concerning decisions regarding the
Plan shall be afforded to any person that is not “disinterested” as that term is used in Rule 16b-3. 

  
 11 

 22. Notices. All Notices by a participant to the Company or other entity designated for a
particular purpose under or in connection with the Plan shall be deemed to have been duly given when received by the Company or other designated entity, or when received in the form specified by the Company at the location, or by the person,
designated by the Company for the receipt thereof. 
 23. Change in Control. In the event of a Change in Control, any offering then in
progress shall be shortened by setting a new Purchase Date specified before the date of the Change in Control, unless the Committee shall, in its sole discretion, provide for the assumption or substitution of outstanding options in a manner
complying with Section 424(a) of the Code. The Administrator shall notify each participant in writing, prior to the new Purchase Date, that the Purchase Date for the participant’s option has been changed to the new Purchase Date and that
the participant’s option shall be exercised automatically on the new Purchase Date, unless prior to such date the participant has withdrawn from an offering then in progress or the Plan as provided in Section 9. 

24. Dissolution or Liquidation of the Company. In the event of the proposed dissolution or liquidation of the Company, the offering then in
progress shall be shortened by setting a new Purchase Date and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Committee in its sole discretion. The new Purchase
Date shall be a specified date before the date of the Company’s proposed dissolution or liquidation. The Administrator shall notify each participant in writing, prior to the new Purchase Date, that the Purchase Date for the participant’s
option has been changed to the new Purchase Date and that the participant’s option shall be exercised automatically on the new Purchase Date, unless prior to such date the participant has withdrawn from an offering then in progress or the Plan
as provided in Section 9. 
 25. Limitations on Sale of Stock Purchased Under the Plan. The Plan is intended to provide Class A
Common Stock for investment and not for resale. The Company does not, however, intend to restrict or influence any employee in the conduct of the employee’s own affairs. An employee, therefore, may sell Class A Common Stock purchased under
the Plan at any time the employee chooses, subject to compliance with any applicable Federal, state or foreign securities laws. THE EMPLOYEE ASSUMES THE RISK OF ANY MARKET FLUCTUATIONS IN THE PRICE OF THE COMPANY’S CLASS A COMMON STOCK. 

26. Governmental Regulation/Compliance with Applicable Law/Separate Offering. The Company’s obligation to sell and deliver shares of the
Company’s Class A Common Stock under this Plan is subject to the approval of any governmental authority required in connection with the authorization, issuance, or sale of such shares. In addition, the terms of an offering under this Plan,
or the rights of an employee under an offering, may be modified to the extent required by applicable law. For purposes of this Plan, the Administrator also may designate separate offerings under the Plan (the terms of which need not be identical) in
which eligible employees of one or more Participating Companies will participate, even if the dates of the offerings are identical. 
 27. No
Employment/Service Rights. Nothing in the Plan shall confer upon any employee the right to continue in employment for any period of specific duration, nor interfere with or otherwise restrict in any way the rights of the Company (or any
Subsidiary or Affiliate employing such person), or of any employee, which rights are hereby expressly reserved by each, to terminate such person’s employment at any time for any reason, with or without cause. 

28. Dates and Times. All references in the Plan to a date or time are intended to refer to dates and times determined pursuant to U.S. Eastern
Time. Business days for purposes of the Plan are U.S. business days. 

  
 12 

 29. Masculine and Feminine, Singular and Plural. Whenever used in the Plan, a pronoun shall include
the opposite gender and the singular shall include the plural, and the plural shall include the singular, whenever the context shall plainly so require. 

30. Governing Law. The Plan shall be governed by the laws of the State of Florida without giving effect to principles of conflict of laws, and
applicable federal law. 
 31. No Liability of Committee Members. No member of the Committee shall be personally liable by reason of any
contract or other instrument executed by such Committee member or on his or her behalf in his or her capacity as a member of the Committee nor for any mistake of judgment made in good faith, and the Company shall indemnify and hold harmless each
member of the Committee and each other employee, officer or director of the Company to whom any duty or power relating to the administration or interpretation of the Plan may be allocated or delegated, against any cost or expense (including counsel
fees) or liability (including any sum paid in settlement of a claim) arising out of any act or omission to act in connection with the Plan unless arising out of such person’s own fraud or willful bad faith; provided, however, that
approval of the Board shall be required for the payment of any amount in settlement of a claim against any such person. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be
entitled under the Company’s Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

transactions to be entered into in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) shall be deemed to have occurred on the date such definitive agreements are entered into and shall be deemed to be
outstanding thereafter for purposes of calculating any baskets or ratios under this Indenture after the date of such definitive agreements and before the consummation of such Limited Condition Acquisition unless and until such Limited Condition
Acquisition or related incurrence of Indebtedness has been abandoned, as determined by the Issuer, prior to the consummation thereof. 

ARTICLE 2. 
 THE NOTES

 Section 2.01 Form Generally. 

Provisions relating to the Notes are set forth in the Rule 144A/Regulation S Appendix hereto (the “Appendix”), which is
hereby incorporated in and expressly made part of this Indenture. The Notes shall be substantially in the form of Exhibit A hereto, with such appropriate insertions, omissions, substitutions and other variations (including, for the avoidance of
doubt, transfer restriction legends) as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of
any securities exchange or as may, consistently herewith, be determined by the Officers executing such Notes as evidenced by their execution of the Notes. 

The certificated Notes shall be printed, lithographed or engraved or produced by any combination of these methods or may be produced in any
other manner, provided that such method is permitted by the rules of any securities exchange on which such Notes may be listed, all as determined by the Officers executing such Notes as evidenced by their execution of such Notes. 

  
 26 

 Section 2.02 Execution, Authentication Delivery and Dating. 

Two Officers shall sign the Notes for the Issuer by manual, facsimile or electronic signature. If an Officer whose signature is on a Note no
longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. 
 A Note shall not be valid until
authenticated by the manual, facsimile or electronic signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

At any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer to
the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes; and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes. 

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual, facsimile or electronic signature of an authorized signatory, and such certificate upon any Note shall be conclusive evidence, and
the only evidence, that such Note has been duly authenticated and delivered hereunder. The Trustee’s certificate of authentication shall be in substantially the following form: 

This is one of the Notes referred to in the within-mentioned Indenture. 

 

							
		 		 	 The Bank of New York Mellon Trust

Company, N.A., as Trustee

				
	Date:
                                    	 		 	By:	 	  

		 		 		 	Authorized Signatory

 Each Note shall be dated the date of its authentication. 

With respect to Notes that are not to be originally issued at one time, the Trustee may conclusively rely, as to the authorization by the
Issuer of any of such Notes, the forms and terms thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel and the other documents delivered pursuant to this Section 2.02, as applicable, in
connection with the first authentication of Notes. 
 Notwithstanding the foregoing, if any Note shall have been duly authenticated and
delivered hereunder but never issued and sold by the Issuer, and the Issuer shall deliver such Note to the Trustee for cancellation as provided in Section 2.13 hereof together with a written statement stating that such Note has never been
issued and sold by the Issuer, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 

Section 2.03 Notes in Global Form. 

Notes issued as a Global Note shall represent such of the outstanding Notes as shall be specified therein and may provide that it shall
represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon or otherwise notated on the books and records of the Registrar and that the aggregate principal amount of outstanding Notes represented thereby may from
time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the aggregate principal amount of any increase or decrease in the amount of outstanding Notes represented thereby
shall be made by the Trustee in such manner and upon instructions given by the Holder thereof. 
 Global Notes may be issued in either
registered or bearer form and in either temporary or permanent form. Permanent Global Notes will be issued in definitive form. 

  
 27 

 The provisions of the last sentence of Section 2.02 hereof shall apply to any Note
represented by a Global Note if such Note was never issued and sold by the Issuer, and the Issuer delivers to the Trustee the Note in global form together with written instructions with regard to the reduction in the principal amount of Notes
represented thereby, together with the written statement contemplated by the last sentence of Section 2.02 hereof. 
 Notwithstanding
the provisions of Sections 2.02 and 2.14 hereof, payment of principal of and any interest on any Global Note shall be made to the person or persons specified therein. 

None of the Issuer, the Trustee, any Paying Agent or Registrar will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Section 2.04 Amount of Notes. 

On the Issue Date, the Trustee shall authenticate and deliver, pursuant to a Company Order, $1,800,000,000 aggregate principal amount of 5.375%
Senior Notes due June 1, 2026 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount specified in a Company Order. Such order shall specify the
amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of an issuance of Additional Notes pursuant to Section 2.16 after the Issue Date, shall certify that such issuance
is in compliance with Section 4.08. The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is unlimited, subject to compliance with Section 4.08 hereof. The Notes may have notations, legends
or endorsements required by law, stock exchange rules or usage. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

All Notes shall be substantially identical except as to the date from which interest shall accrue, any applicable transfer restrictions and
except as may otherwise be provided in any indenture supplemental hereto. 
 If any of the terms of the Notes are established by action
taken pursuant to a Board Resolution, a copy of any appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Issuer and delivered to the Trustee at or prior to the delivery of the Officers’
Certificate setting forth the terms of the Notes. 
 Section 2.05 Registrar and Paying Agent. 

The Issuer shall maintain, with respect to the Notes, an office or agency where Notes may be presented for registration of transfer or for
exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”) in the Borough of Manhattan, the City of New York. The Registrar shall keep a register (the
“Note Register”) of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term
“Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The
Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar of Paying Agent, the Trustee shall act as such. The Company or any
of its Restricted Subsidiaries may act as Paying Agent or Registrar. 
 The Issuer initially appoints The Depository Trust Company
(“DTC”) to act as Depositary with respect to the Global Notes. 
 The Issuer initially appoints the Trustee to act
as Registrar and Paying Agent and to act as Custodian with respect to the Global Notes, and the Trustee hereby agrees so to initially act. 

Section 2.06 Paying Agent to Hold Money in Trust. 

The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent will hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all 

  
 28 

 
funds held by it relating to the Notes to the Trustee. The Issuer at any time may require a Paying Agent to pay all funds held by it to the Trustee. Upon payment over to the Trustee, the Paying
Agent (if other than the Company or a Restricted Subsidiary) shall have no further liability for such funds. If the Company or a Restricted Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the
Holders all funds held by it as Paying Agent. Upon any Event of Default under Sections 6.01(i) and (j) hereof relating to the Issuer, the Trustee shall serve as Paying Agent for the Notes. 

Section 2.07 Holder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
all Holders. If the Trustee is not the Registrar, the Issuer shall furnish or cause to be furnished to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list
in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders. 
 Section 2.08
Registration; Registration of Transfer and Exchange. 
 The Notes shall be transferable only in compliance with the Appendix. Upon
surrender for registration of transfer of any Notes at an office or agency of the Issuer designated pursuant to Section 4.02 hereof for such purpose, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Notes of any authorized denominations, of a like aggregate principal amount. The Issuer shall not charge a service charge for any registration of transfer or exchange, but the Issuer may require
payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Notes from the Holder requesting such transfer or exchange (other than any exchange of a
temporary Note for a permanent Note not involving any change in ownership or any exchange pursuant to Sections 2.12, 3.06 or 9.04 hereof, not involving any transfer). 

Notwithstanding any other provisions (other than the provisions set forth in the fourth paragraph) of this Section 2.08, a Global Note
representing all or a portion of the Notes may not be transferred except as a whole by the Depositary to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary
or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 Each Global Note is exchangeable for Notes in
certificated form only if (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as Depositary for such Global Notes or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act
and the Issuer fails within 90 days thereafter to appoint a successor Depositary, (ii) the Issuer in its sole discretion determines that such Global Note shall be exchangeable or (iii) there shall have occurred and be continuing an Event
of Default with respect to the Notes represented by such Global Notes. In any such event the Issuer will issue, and the Trustee, upon receipt of a Company Order for the authentication and delivery of certificated Notes, will authenticate and deliver
Notes in certificated form in exchange for such Global Note. In any such instance, an owner of a beneficial interest in either Global Note will be entitled to physical delivery in certificated form of Notes equal in principal amount to such
beneficial interest and to have such Notes registered in its name. Notes so issued in certificated form will be issued in denominations of $2,000 or any larger amount that is an integral multiple of $1,000, will be issued in registered form only,
without coupons, and will bear transfer restriction legends when required by the Appendix. 
 Upon the exchange of a Global Note for Notes
in certificated form, such Global Note shall be cancelled by the Trustee. All cancelled Notes held by the Trustee shall be disposed of by the Trustee and, upon written request by the Issuer, a certificate of their disposal delivered to the Issuer.
Definitive Notes issued in exchange for a Global Note pursuant to this Section 2.08 hereof shall be registered in such names and in such authorized denominations as the Depositary for such Note in global form, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Notes as instructed in writing by the Depositary. 

At the option of the Holders of certificated Notes, certificated Notes may be exchanged for other certificated Notes of any authorized
denomination or denominations of like aggregate principal amount and tenor, upon surrender of the certificated Notes to be exchanged at such office or agency. Whenever any certificated Notes are so surrendered for exchange, the Issuer shall execute,
and the Trustee shall authenticate and deliver, the certificated Notes which the Holder making the exchange is entitled to receive. 

  
 29 

 All Notes issued upon any registration of transfer or exchange of Notes pursuant to the terms of
this Indenture shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

Every Note presented or surrendered for registration of transfer or for exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Issuer and the Registrar duly executed, by the Holder thereof or his or her attorney duly authorized in writing. 

The Issuer shall not be required (i) to issue, register the transfer of or exchange any Notes during a period beginning 15 Business Days
before any selection of Notes to be redeemed and ending at the close of business on the day of the sending of the relevant notice of redemption or (ii) to register the transfer of or exchange any Note so selected for redemption, in whole or in
part, except the unredeemed portion of any Note being redeemed in part. 
 Section 2.09 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction,
loss or theft of any Note, the Issuer shall issue and, upon receipt of a Company Order, the Trustee shall authenticate a replacement Note. If required by the Trustee or the Issuer, the Holder of such Note shall provide indemnity that is sufficient,
in the judgment of the Trustee or the Issuer, to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer in connection with such replacement. If required by the Issuer, such Holder shall
reimburse the Issuer for its reasonable expenses in connection with such replacement. 
 Every replacement Note issued in accordance with
this Section 2.09 shall be the valid obligation of the Issuer, evidencing the same debt as the destroyed, lost or stolen Note, and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly
issued hereunder. 
 Section 2.10 Outstanding Notes. 

The Notes outstanding at any time shall be the entire principal amount of Notes represented by all of the Global Notes and Definitive Notes
authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those subject to reductions in beneficial interests effected by the Trustee in accordance with the provisions hereof, and those described in this
Section 2.10 as not outstanding. Except as set forth in Section 2.11 hereof, a Note shall not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. 

If a Note is replaced pursuant to Section 2.09 hereof, it shall cease to be outstanding unless the Trustee receives proof satisfactory to
it that the replaced Note is held by a bona fide purchaser. 
 If the principal amount of any Note is considered paid under
Section 4.01 hereof, it shall cease to be outstanding and interest on it shall cease to accrue. 
 If the Paying Agent (other than the
Company, a Subsidiary or an Affiliate of any thereof) holds, on a Redemption Date, a Purchase Date or a maturity date, funds sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer
outstanding and shall cease to accrue interest. 
 Section 2.11 Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by
the Issuer, or by any Affiliate of the Issuer, shall be disregarded and deemed not to be outstanding, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes
that a Responsible Officer of the Trustee knows are so owned shall be so disregarded. 

  
 30 

 Section 2.12 Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Issuer may prepare and, upon receipt of a Company Order in accordance with
Section 2.02 hereof, the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes and as shall be
reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Global Notes or Definitive Notes in exchange for temporary Notes, as applicable. After preparation of Definitive Notes, the
temporary Note will be exchangeable for Definitive Notes upon surrender of the temporary Notes. 
 Holders of temporary Notes shall be
entitled to all of the benefits of this Indenture as permanent Notes. 
 Section 2.13 Cancellation. 

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of cancelled Notes
(subject to the record retention requirement of the Exchange Act or other applicable laws) unless by written order, signed by an Officer of the Issuer, the Issuer directs them to be returned to it. 

Certification of the disposal of all cancelled Notes shall be delivered to the Issuer from time to time upon request. The Issuer may not issue
new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.14 Payment of
Interest; Defaulted Interest. 
 Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest. 

If the Issuer defaults in a payment of interest on the Notes which is payable (“Defaulted Interest”), it shall pay the
Defaulted Interest in any lawful manner plus, to the extent lawful, interest payable on the Defaulted Interest, to the Persons who are Holders on a subsequent Special Record Date, in each case at the rate provided in the Notes. The Issuer shall
notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Notes and the date of the proposed payment. The Issuer shall fix or cause to be fixed each such Special Record Date and payment date; provided that
no such Special Record Date shall be less than 10 days prior to the related payment date for such Defaulted Interest. At least 15 days before the Special Record Date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name
and at the expense of the Issuer) shall send or cause to be sent to Holders a notice that states the Special Record Date, the related payment date and the amount of such interest to be paid. 

Subject to the foregoing provisions of this Section 2.14 and Section 2.08 hereof, each Note delivered under this Indenture upon
registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. 

Section 2.15 CUSIP or ISIN Numbers. 

The Issuer in issuing the Notes may use “CUSIP” and/or “ISIN” numbers (if then generally in use), and, if so, the Trustee
shall use “CUSIP” and/or “ISIN” numbers in notices of redemption or Offers to Purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or notice of an Offer to Purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such
redemption or Offer to Purchase shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee of any change in the “CUSIP” and/or “ISIN” numbers. 

  
 31 

 Section 2.16 Additional Notes. 

The Issuer shall be entitled, subject to its compliance with Section 4.08 hereof, to issue Additional Notes under this Indenture which
shall have identical terms as the Initial Notes issued on the date hereof, other than with respect to the date of issuance and issue price and any applicable transfer restrictions. The Initial Notes issued on the date hereof and any Additional Notes
shall be treated as a single class for all purposes under this Indenture, including directions, waivers, amendments, consents, redemptions and Offers to Purchase; provided, however, that if Additional Notes are issued following the
Assumption Date, such Additional Notes shall not be subject to Sections 3.09, 4.18 and 4.19; provided, further, that in the event that any Additional Notes are not fungible with the Initial Notes for federal income tax purposes,
such non-fungible Additional Notes shall be issued with a separate CUSIP number and ISIN so they are distinguishable from the Initial Notes. 

With respect to any Additional Notes, the Issuer shall set forth in an Officers’ Certificate, a copy of each of which shall be delivered
to the Trustee, the following information: 
 (1) the aggregate principal amount of such Additional Notes to be
authenticated and delivered pursuant to this Indenture;

ISIN number of such Additional Notes; and 
 (3) whether such Additional Notes shall be Transfer Restricted Notes.

 Section 2.17 Record Date. 

Except as otherwise provided or unless the context otherwise requires, such record date shall be the later of five (5) days prior to the
first solicitation of such consent or the date of the most recent list of holders furnished to the Trustee. 
 Section 2.18 Persons
Deemed Owners. 
 Prior to due presentment of a Note for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or
the Trustee may treat the person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of and (except as otherwise specified as contemplated by the first paragraph of Section 2.04
hereof and subject to Sections 2.07 and 2.13 hereof) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Issuer, the Trustee nor any agent of the Issuer or the Trustee shall be
affected by notice to the contrary. 
 None of the Issuer, the Trustee, any Paying Agent or the Registrar will have any responsibility or
liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Note in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Section 2.19 Computation of Interest. 

Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest on the Initial Notes will accrue from May 23, 2018.

Section 3.01 Notices to Trustee. 

Except as set forth in paragraph 5 of the Notes set forth in Exhibit A, the Issuer will not be entitled to redeem the Notes at its

 The Trustee
shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of
$2,000 or integral multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not an integral multiple of $1,000, shall be redeemed. Except as provided in
the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

Section 3.03 Notice of Redemption. 

At least 15 days but not more than 60 days prior to a Redemption Date, the Issuer shall send or cause to be sent, by electronic transmission
(for Global Notes) or first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at such Holder’s registered address appearing in the Note Register, except that redemption notices may be sent more than 60 days prior
to a Redemption Date if the notice is issued in connection with a defeasance pursuant to Article 8 hereof, a satisfaction and discharge pursuant to Article 11 hereof or a redemption of the Notes subject to one or more conditions precedent.

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

(a) the Redemption Date; 
 (b) the
appropriate method for calculation of the redemption price, but need not include the Redemption Price itself; the actual Redemption Price shall be set forth in an Officers’ Certificate delivered to the Trustee no later than two
(2) Business Days prior to the Redemption Date. 
 (c) if any Note is being redeemed in part, the portion of the principal amount of
such Note to be redeemed and that, after the Redemption Date upon surrender of such Note, if applicable, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; 

(d) the name and address of the Paying Agent; 

(e) that Notes called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the Redemption

 (g) the applicable section of this Indenture pursuant to which the Notes called for redemption are being
redeemed; and 
 (h) the CUSIP and/or ISIN numbers, if any, printed on the Notes; provided, however, that such notice may state
that no representation is made as to the correctness of such numbers. 
 At the Issuer’s request, the Trustee shall give the notice of
redemption in the Issuer’s name and at its expense; provided, however, that the Issuer shall have delivered to the Trustee, at least 15 days (or such shorter period allowed by the Trustee), prior to the Redemption Date, an
Officers’ Certificate requesting that the Trustee give such notice (in the name and at the expense of the Issuer) and setting forth the information to be stated in such notice as provided in this Section 3.03. 

  
 33 

 Section 3.04 Effect of Notice of Redemption. 

Subject to the following paragraph, once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption
shall become irrevocably due and payable on the Redemption Date at the Redemption Price. 
 Any redemption of the Notes may, at the
Issuer’s discretion, be subject to one or more conditions precedent. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the
Redemption Date may be delayed until such time as any or all of such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such
conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the Redemption Date, or by the Redemption Date so delayed. 

Section 3.05 Deposit of Redemption Price. 

On or prior to 11:00 a.m. Eastern time on the Business Day prior to any Redemption Date, the Issuer shall deposit with the Trustee or with the
Paying Agent (or, if the Company or any of its Restricted Subsidiaries is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of and, if applicable, accrued and unpaid interest on all Notes to be
redeemed on that date. The Trustee or the Paying Agent shall promptly, and in any event within two (2) Business Days after the Redemption Date, return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in
excess of the amounts necessary to pay the Redemption Price of, and accrued and unpaid interest, if any, on, all Notes to be redeemed. 
 If
the Issuer complies with the provisions of the preceding paragraph, on and after the Redemption Date, interest shall cease to accrue on the Notes or the portions of Notes called for purchase or redemption in accordance with Section 2.08 hereof,
whether or not such Notes are presented for payment. If a Note is redeemed on or after a Regular Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose
name such Note was registered at the close of business on such Regular Record Date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph,
interest shall be paid on the unpaid principal from the Redemption Date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01
hereof. 
 Section 3.06 Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Issuer shall issue and, upon receipt of a Company Order in accordance with

 34 

 (1) that the Offer to Purchase is being made pursuant to this
Section 3.08 and Sections 4.11 or 4.15, as the case may be, and, in the case of a Change of Control Offer, that a Change of Control has occurred, the circumstances and relevant facts regarding the Change of Control and that a Change of

Holders electing to have a Note purchased pursuant to an Offer to Purchase may elect to have Notes purchased equal to $2,000 or in integral multiples of $1,000 only; 

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

(9) that, in the case of an Asset Sale Offer, if the aggregate principal amount of Notes surrendered by Holders exceeds
the 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 the Company so that only Notes in denominations of $2,000 or integral multiples of $1,000 shall be
purchased); 
 (10) that Holders whose Notes were purchased in part shall be issued new Notes equal in principal

(g) If the Purchase Date is on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid

 (h) The
Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are
applicable in connection with the Offer to Purchase. To the extent that the provisions of any securities laws or regulations conflict with Sections 4.11 or 4.15, as applicable, this Section 3.08 or other provisions of this Indenture, the
Company shall comply with applicable securities laws and regulations and shall not be deemed to have breached its obligations under Sections 4.11 or 4.15, as applicable, this Section 3.08 or such other provision by virtue of such
compliance. 
 (i) If Holders of not less than 90% of the aggregate principal amount of the outstanding Notes validly tender and do not
withdraw such Notes in an Offer to Purchase and the Issuer (or any third party making a Change of Control Offer in lieu of the Issuer as described in Section 4.15(b)) purchases all of the Notes validly tendered and not withdrawn by such
Holders, the Issuer or such third party, as the case may be, shall have the right, upon at least 15 but not more than 60 days prior notice, given not more than 30 days following such initial purchase, to purchase all of the Notes that remain
outstanding following such initial purchase at a price equal to the price offered to each other Holder in the applicable Offer to Purchase, plus accrued and unpaid interest, if any, to, but excluding, the date of such second purchase (subject to the
rights of Holders of the Notes of record on the relevant Record Date to receive interest due on an Interest Payment Date falling prior to such second purchase date). 

(j) Other than as specifically provided in this Section 3.08, any purchase pursuant to this Section 3.08 shall be made in accordance
with the provisions of Sections 3.01 through 3.06 hereof.

(a) If (i) the Fidelis Acquisition is not completed on or before September 1, 2018, or (ii) on a date prior to September 1,
2018, the Asset Purchase Agreement is terminated or the Company or the Escrow Issuer notifies the Trustee and the Escrow Agent or otherwise announces that the Asset Purchase Agreement has been or will be terminated or that the Company has determined
that the Fidelis Acquisition will not otherwise be pursued (the earlier of such dates, the “Outside Date”), then the Issuer shall, no later than three Business Days following the Outside Date (the “Special
Mandatory Redemption Date”), redeem the Notes (the “Special Mandatory Redemption”) at a redemption price equal to 100.0% of the aggregate principal amount of the Notes, plus accrued and unpaid interest, if any,
from the Issue Date to, but not including, the Special Mandatory Redemption Date (subject to the right of Holders on the relevant record date to receive interest due on an interest payment date falling prior to the Special Mandatory Redemption Date)
(the “Special Mandatory Redemption Price”). 

  
 36 

 (b) Notice of the Special Mandatory Redemption shall be sent by the Issuer no later than the next
Business Day following the Outside Date to each Holder of the Notes, the Trustee and the Escrow Agent. 
 (c) All notices of the Special
Mandatory Redemption shall state: 
 (1) the Special Mandatory Redemption Date; 

(2) the Special Mandatory Redemption Price; 

(3) that on the Special Mandatory Redemption Date, the Special Mandatory Redemption Price shall become due and payable;

 (4) the place or places where the Notes are to be surrendered for payment of the Special Mandatory Redemption
Price;

 (d) Subject to the terms of the Escrow Agreement, upon receipt
of the notice of Special Mandatory Redemption, the Escrow Agent shall liquidate no later than the last Business Day prior to the Special Mandatory Redemption Date, a portion of the Escrowed Property then held by it sufficient, as determined solely
by the Issuer, to pay the aggregate Special Mandatory Redemption Price. If at the time the notice of Special Mandatory Redemption is delivered the aggregate value of the Escrowed Property is less than an amount (the “Aggregate Release
Amount”) equal to the sum of the (x) Special Mandatory Redemption Price on the Special Mandatory Redemption Date and (y) aggregate fees and commission payable to the initial purchasers under the Purchase Agreement (the
“Initial Purchasers’ Commission”), the Issuer shall deposit or cause to be deposited into the Escrow Account, on the Business Day prior to the Special Mandatory Redemption Date, an amount in
cash equal to the absolute value of such difference such that the amount of the Escrowed Property will be sufficient to pay the Special Mandatory Redemption Price and the Initial Purchasers’ Commission on the Special Mandatory Redemption Date.
On the Special Mandatory Redemption Date, the Escrow Agent shall pay to (i) a paying agent for payment to each Holder the Special Mandatory Redemption Price for such Holder’s Notes and (ii) Citigroup Global Markets Inc. on behalf of
the initial purchasers, the Initial Purchasers’ Commission. After the Special Mandatory Redemption Date and the payment of the Special Mandatory Redemption Price, all interest earned on the Escrowed Property and any other Escrowed Property that
is not required to be applied towards the Special Mandatory Redemption and the Initial Purchasers’ Commission shall be paid to the Company upon the Issuer’s request in accordance with the terms of the Escrow Agreement and the Company may
use such funds at its discretion. 
 (e) The Notes shall, on the Special Mandatory Redemption Date, become due and payable, and shall be paid
by the Issuer, at the Special Mandatory Redemption Price. The Notes shall cease to bear interest on and after the Special Mandatory Redemption Date.

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 Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

one such office, drop facility or agency of the Issuer in accordance with Section 2.05 hereof. 
 Section 4.03 SEC Reports.

 (a) Whether or not required, so long as the Notes are outstanding the Issuer will file with the SEC (unless the SEC will not accept
such filing), within the time periods specified in the SEC’s rules and regulations and deliver to the Trustee within 15 days after the filing of the same would be required by the SEC, copies of the quarterly and annual reports and of the
information, documents and other reports, if any, which the Issuer would be required to file with the SEC if subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act. Notwithstanding that the Issuer may not be subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long as the Notes are outstanding the Issuer will file with the SEC, to the extent permitted, and provide the Trustee with such annual reports and such information,
documents and other reports specified in Sections 13 and 15(d) of the Exchange Act within the time periods specified in the SEC’s rules and regulations. The Issuer will be deemed to have furnished such reports referred to in this section
to the Trustee and the Holders of the Notes if the Issuer has filed such reports with the SEC via the EDGAR filing system and such reports are publicly available. 

(b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of
such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officers’ Certificates). 
 Section 4.04 Compliance Certificate. 

(a) The Issuer shall deliver to the Trustee, within 120 days after the end of each fiscal year, commencing with the fiscal year ending
December 31, 2018, an Officers’ Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year, has been made under the supervision of the signing Officers with a view to determining
whether the Issuer and its Subsidiaries have kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Issuer
and its Subsidiaries have kept, observed, performed and fulfilled 

  
 38 

 
each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto) and that to the best of his or her knowledge
no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer
is taking or proposes to take with respect thereto. 
 (b) The Issuer shall deliver to the Trustee, within 30 days after the occurrence or
becoming aware thereof, written notice in the form of an Officers’ Certificate of any event that with the giving of notice and/or the lapse of time would become an Event of Default, its status and what action the Issuer is taking or proposes to
take with respect thereto. 
 Section 4.05 Taxes. 

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

Section 4.06 Stay, Extension and Usury Laws. 

The Issuer covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law has been enacted. 
 Section 4.07 Organizational Existence. 

Subject to Article 5 hereof, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect
(i) its organizational existence, and that of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Restricted Subsidiary and
(ii) the rights (charter and statutory), licenses and franchises of the Issuer and its Restricted Subsidiaries; provided, however, that the Issuer shall not be required to preserve any such right, license or franchise, or the
organizational existence of any Restricted Subsidiary, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole.
Notwithstanding the foregoing, this Section 4.07 shall not apply to the consummation of the Escrow Merger and the Assumption. 

Section 4.08 Incurrence of Indebtedness and Issuance of Preferred Stock. 

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Issuer will not issue any Disqualified Stock
and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock (including Disqualified Stock) other than to the Issuer; provided, however, that the Issuer may incur Indebtedness (including Acquired Debt)
or issue Disqualified Stock, and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Fixed Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such preferred stock or Disqualified Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the preferred stock or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period.;
provided, further, that Restricted Subsidiaries that are not Guarantors may not incur Indebtedness or issue Disqualified Stock in reliance on this Section 4.08(a) if, after giving pro forma effect to such incurrence or issuance
(including a pro forma application of 

  
 39 

 
the net proceeds therefrom), the aggregate amount of such Indebtedness and Disqualified Stock of Restricted Subsidiaries that are not Guarantors outstanding under this Section 4.08(a)
(excluding, for the avoidance of doubt, the aggregate amount of Indebtedness incurred by such Restricted Subsidiaries and then outstanding as Permitted Debt) exceeds $500.0 million. 

(b) So long as no Default shall have occurred or be continuing or would be caused thereby, Section 4.08(a) will not prohibit the
incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
 (1)
the incurrence by the Issuer or any Restricted Subsidiary of the Issuer of additional Indebtedness and letters of credit under one or more Credit Facilities; provided that the aggregate principal amount of all Indebtedness and letters of
credit of the Issuer and any Restricted Subsidiary of the Issuer incurred pursuant to this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Issuer and any Restricted
Subsidiaries thereunder) does not exceed the greater of (x) $3,500.0 million and (y) 20.0% of Consolidated Total Assets (less the aggregate principal amount of Indebtedness incurred by Securitization Subsidiaries and then outstanding
pursuant to clause (13)); 
 (2) the incurrence by the Issuer and any of its Restricted Subsidiaries of the Existing
Indebtedness; 
 (3) the incurrence by the Issuer and any of its Restricted Subsidiaries of Indebtedness represented

 (4) the incurrence by the Issuer or any of its Restricted
Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement
of property, plant or equipment used in the business of the Issuer or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred
pursuant to this clause (4), not to exceed the greater of (x) $800.0 million and (y) 2.5% of Consolidated Total Assets at any time outstanding; 

(5) the incurrence by the Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange
for, or which serves to extend, defease, renew, refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was incurred under Section 4.08(a) or clauses (2), (3), (4), (12), (18), (22) or this clause (5) of
this Section 4.08(b); 
 (6) the incurrence by the Issuer or any of its Restricted Subsidiaries of intercompany
Indebtedness between or among the Issuer and/or any of its Restricted Subsidiaries; provided, however, that (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person
other than the Issuer or a Restricted Subsidiary of the Issuer and (ii) any subsequent sale or other transfer of any such Indebtedness to a Person that is not either the Issuer or a Restricted Subsidiary of the Issuer shall be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

(7) Indebtedness arising from agreements of the Issuer or any of its Restricted Subsidiaries providing for
indemnification, adjustment of purchase price, earn out or other similar Obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, assets or shares of Capital Stock of a Restricted Subsidiary
of the Issuer, other than Guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or shares of Capital Stock of a Restricted Subsidiary for the purpose of financing such acquisition; 

(8) the incurrence of Indebtedness of the Issuer or any of its Restricted Subsidiaries represented by (a) letters
of credit for the account of the Issuer or any of its Restricted Subsidiaries or (b) other obligations to reimburse third parties pursuant to any surety bond, performance bond or other similar arrangements, which letters of credit or other
obligations, as the case may be, are intended to provide security for provider claims, workers’ compensation claims, payment obligations in connection with sales tax and insurance or other similar requirements in the ordinary course of
business; 

  
 40 

 (9) the incurrence by the Issuer or any of its Restricted Subsidiaries of
Hedging Obligations; provided that such Hedging Obligations are related to business transactions of the Issuer or its Restricted Subsidiaries entered into in the ordinary course of business and are entered into for bona fide hedging purposes
(and not for speculative purposes) of the Issuer or its Restricted Subsidiaries (as determined in good faith by the Board of Directors or senior management of the Issuer); 

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

(11) Indebtedness incurred by a Foreign Restricted Subsidiary which, when aggregated with the principal amount of all
other Indebtedness incurred pursuant to this clause (11) and then outstanding, does not exceed the greater of (x) $1,000.0 million or (y) 3.25% of the Issuer’s Consolidated Total Assets; 

(12) Acquired Debt or other Indebtedness, which in the case of other Indebtedness, is incurred reasonably
contemporaneously to finance an acquisition, merger, consolidation or amalgamation; provided that after giving effect thereto, (a) the Issuer would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed
Charge Coverage Ratio test in Section 4.08(a), or (b) the Fixed Charge Coverage Ratio for the four full fiscal quarters immediately preceding such incurrence for which internal financial statements are available would be no worse than
immediately prior thereto; 
 (13) Indebtedness incurred by a Securitization Subsidiary in connection with a Qualified
Securitization Transaction that is not recourse with respect to the Issuer and its Restricted Subsidiaries; provided, however, that in the event such Securitization Subsidiary ceases to qualify as a Securitization Subsidiary or such
Indebtedness becomes recourse to the Issuer or any of its Restricted Subsidiaries, such Indebtedness will, in each case, be deemed to be, and must be classified by the Issuer as, incurred at such time (or at the time initially incurred) under one or
more of the other provisions of this Section 4.08; 
 (14) the incurrence by the Issuer or any Restricted
Subsidiary of the Issuer of Indebtedness to the extent the proceeds thereof are used to purchase Notes pursuant to a Change of Control Offer, Asset Sale Offer or to defease, discharge, repurchase or redeem the Notes, in each case, in accordance with
the terms of this Indenture; 
 (15) the incurrence by the Issuer or any Restricted Subsidiary of the Issuer of
Indebtedness consisting of (a) the financing of insurance premiums or (b) take or pay obligations in supply agreements, in each case in the ordinary course of business;

secured or unsecured letters of credit incurred by the Issuer or any Restricted Subsidiary of the Issuer in an aggregate principal amount not to exceed $750.0 million;

clause (18), not to exceed the greater of (x) $1,600.0 million and (y) 5.0% of Consolidated Total Assets; 

(19) Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer arising from the honoring by a bank or other

 41 

 (20) Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer
in respect of cash management services entered into in the ordinary course of business and Guarantees of the Obligations of the Issuer or any Restricted Subsidiary in respect of such Indebtedness; 

(21) Indebtedness incurred by the Issuer or any Restricted Subsidiary of the Issuer to the extent that the net proceeds
thereof are promptly deposited with the Trustee to satisfy and discharge the Notes or exercise the Issuer’s right to effect Legal Defeasance or Covenant Defeasance, in each case in accordance with this Indenture; and 

(22) Indebtedness or Disqualified Stock of the Issuer or any of its Restricted Subsidiaries that, when taken together
with the principal amount of all other Indebtedness incurred pursuant to this clause (22) and then outstanding, will not exceed in aggregate principal amount 100.0% of the aggregate net cash proceeds and the Fair Market Value of property other
than cash received by the Issuer since February 11, 2016 as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Issuer (other than Disqualified Stock) or from the issue or sale of convertible or
exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Issuer, in either case, that have been converted into or exchanged for such Equity Interests of the Issuer (other than Equity Interests or Disqualified Stock or
debt securities sold to a Restricted Subsidiary of the Issuer); provided, however, that (a) any such net cash proceeds or other property that is so received or contributed shall not increase the amount available for making
Restricted Payments under clause (C)(II) of Section 4.09(a) to the extent that the Issuer or any of its Restricted Subsidiaries incurs Indebtedness in reliance thereon under this clause (22) and (b) any such net cash proceeds or other
property that is so received or contributed shall be excluded for purposes of determining the amount of Indebtedness that may be incurred under this clause (22) to the extent that such net cash proceeds or other property have been applied to
make Restricted Payments or other payments, redemptions, repurchases, retirements, repayments, defeasances or other acquisitions pursuant to Section 4.09(b). 

(c) For purposes of determining compliance with this Section 4.08, in the event that an item of Indebtedness meets the criteria of more
than one of the categories of Permitted Debt described in clauses (1) through (22) of Section 4.08(b) or is entitled to be incurred pursuant to Section 4.08(a), in each case, as of the date of incurrence thereof, the Issuer
shall, in its sole discretion, classify (or later reclassify in whole or in part), or divide (or later redivide in whole or in part) such item of Indebtedness (or any portion thereof) in any manner that complies with this Section 4.08 and such
Indebtedness will be treated as having been incurred pursuant to such clauses or Section 4.08(a) hereof, as the case may be, designated by the Issuer. Indebtedness under Credit Facilities outstanding on the Issue Date or the Assumption Date
will at all times be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest or dividends, the accretion or amortization of original issue
discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Equity Interests as Indebtedness due to a change in accounting principles, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.08. Guarantees of, or
obligations in respect of letters of credit, bankers’ acceptances or other similar instruments relating to, or Liens securing, Indebtedness that is otherwise included in the determination of a particular amount of Indebtedness will not be
deemed to be an incurrence of Indebtedness for purposes of this Section 4.08. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Issuer or any Restricted Subsidiary of the Issuer may incur pursuant
to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 The amount of
Indebtedness outstanding as of any date shall be (1) the accreted value thereof, in the case of any Indebtedness issued with original issue discount, (2) the principal amount thereof, in the case of any other Indebtedness, (3) in the
case of the Guarantee by the specified Person of any indebtedness of any other Person, the maximum liability to which the specified Person may be subject upon the occurrence of the contingency giving rise to the obligation and (4) in the case
of Indebtedness of others Guaranteed by means of a Lien on any asset of the specified Person, the lesser of (A) the Fair Market Value of such asset on the date on which Indebtedness is required to be determined pursuant to this Indenture and
(B) the amount of the Indebtedness so secured. The amount of any category of Permitted Refinancing Indebtedness outstanding as of any date shall not include the aggregate amount of fees, underwriting discounts, accrued and unpaid interest,
premiums (including tender premiums) and other costs and expenses (including original issue discount, upfront fees or similar fees) (collectively “Permitted Refinancing Expenses”) paid or incurred by the Issuer
or any of its Restricted Subsidiaries in connection with the incurrence of such Permitted Refinancing Indebtedness since the Issue Date. 

  
 42 

 (d) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Issuer or such Restricted Subsidiary, as the case may be, unless made expressly
subordinate to the Notes to the same extent and in the same manner as such Indebtedness is subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Issuer or such Restricted
Subsidiary, as the case may be. 
 (e) This Indenture will not treat (1) unsecured Indebtedness as subordinated or junior to
Indebtedness secured by a Lien merely because it is unsecured, (2) senior Indebtedness as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral or is secured by
different collateral or because it is Guaranteed by different obligors, (3) Indebtedness which is not Guaranteed as subordinated or junior to Indebtedness that is Guaranteed merely because of such Guarantee and (4) Indebtedness secured by
a Lien as subordinated because of the application of waterfall or other payment-ordering or collateral-sharing provisions affecting such Indebtedness. 

Section 4.09 Restricted Payments. 

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 

(1) declare or pay any dividend or make any other payment or distribution (A) on account of the Issuer’s or
any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Issuer or any of its Restricted Subsidiaries) or (B) to the direct or indirect
holders of the Issuer’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends, payments or distributions (i) payable in Equity Interests (other than Disqualified Stock) of the Issuer
or (ii) to the Issuer or a wholly owned Restricted Subsidiary of the Issuer or to all holders of Capital Stock of a Restricted Subsidiary of the Issuer on a pro rata basis); 

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any
merger or consolidation involving the Issuer) any Equity Interests of the Issuer or any of its Restricted Subsidiaries (other than any such Equity Interests owned by the Issuer or any of its Restricted Subsidiaries); 

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Subordinated Obligations, except a payment of interest or principal at the Stated Maturity thereof; or 
 (4) make any
Restricted Investment (all such payments and other actions set forth in clauses (1) through (3) above and this clause (4) being collectively referred to as “Restricted Payments”), 

unless, at the time of and after giving effect to such Restricted Payment: 

(A) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;
and 
 (B) the Issuer would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such
Restricted Payment had been made at the beginning of the most recently ended four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.08(a); and 

  
 43 

 (C) such Restricted Payment, together with the aggregate amount of all other
Restricted Payments made by the Issuer and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (b)(2), (3), (4), (5), (6), (7), (8) and (9) of this Section 4.09, is less than the sum,
without duplication, of: 
 (I) 50.0% of the Consolidated Net Income of the Issuer for the period (taken as one accounting
period) from the beginning of the fiscal quarter ended March 31, 2016 to the end of the Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such
Consolidated Net Income for such period is a deficit, less 100.0% of such deficit), plus 
 (II) 100.0% of the
aggregate net cash proceeds (and the Fair Market Value of property other than cash) received by the Issuer and its Restricted Subsidiaries since February 11, 2016 as a contribution to its common equity capital or from the issue or sale of
Equity Interests of the Issuer (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Issuer, in either case, that have been converted into or
exchanged for such Equity Interests of the Issuer (other than Equity Interests or Disqualified Stock or debt securities sold to a Subsidiary of the Issuer) (subject, in each case of this clause (C)(II), to the proviso set forth in clause
(22) of Section 4.08(b), plus 
 (III) to the extent that any Restricted Investment that was made after
February 11, 2016 is sold for cash or otherwise liquidated or repaid for cash, the cash proceeds and Fair Market Value, of property and marketable securities received with respect to such Restricted Investment (less the cost of disposition, if
any), plus 
 (IV) to the extent any Unrestricted Subsidiary has been redesignated as a Restricted Subsidiary of the
Issuer under the terms of this Indenture or has been merged, consolidated or amalgamated with or into, or transfers or conveys assets to, or is liquidated into the Issuer or a Restricted Subsidiary of the Issuer, an amount equal to the Fair Market
Value of the Issuer’s and the Restricted Subsidiaries’ aggregate Investment in such Unrestricted Subsidiary as of the date of such redesignation, combination or transfer (or of the assets transferred or conveyed, as applicable),
plus 
 (V) $700.0 million. 

(b) So long as no Default or Event of Default has occurred and is continuing or would be caused thereby, the preceding provisions will not
prohibit: 
 (1) the payment of any dividend or consummation of any redemption within 60 days after the date of
declaration of the dividend or the giving of a redemption notice, respectively, if at the date of declaration or the giving of a redemption notice, the dividend payment or redemption, respectively, would have complied with the provisions of this
Indenture; 
 (2) the redemption, repurchase, retirement, repayment, defeasance or other acquisition of any
Subordinated Obligations or of any Equity Interests of the Issuer in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Issuer) of, Equity Interests of the Issuer (other
than Disqualified Stock); provided, however, that the amount of any such net cash proceeds from such sale that are utilized for any such redemption, repurchase, retirement, repayment, defeasance or other acquisition will be excluded
from clause (C)(II) of Section 4.09(a); 
 (3) the redemption, repurchase, repayment, retirement, defeasance or
other acquisition of any Subordinated Obligations with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; provided, however, that the amount of any such net cash proceeds that are utilized for any such
redemption, repurchase, repayment, retirement, defeasance or other acquisition will be excluded from clause (C)(II) of Section 4.09(a); 

  
 44 

 (4) the redemption, repurchase or other acquisition or retirement for
value of any Equity Interests of the Issuer or any Restricted Subsidiary of the Issuer (a) held by any current or former director, officer, employee or consultant (or the estate, heirs, family members, spouse, former spouse, domestic partner or
former domestic partner of any of the foregoing) of the Issuer (or any of its Restricted Subsidiaries) pursuant to any management equity subscription plan or agreement, stock option or stock purchase plan or agreement or employee benefit plan as may
be adopted by the Issuer from time to time or pursuant to any agreement with any director, officer, employee or consultant of the Issuer or (b) from an employee of the Issuer upon the termination of such employee’s employment with the
Issuer; provided, however, that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests in reliance on this clause (4) may not exceed $30.0 million in any twelve-month period, with
any unused amounts in any twelve-month period being carried forward to the next two succeeding twelve-month periods; and provided, further, that such amount in any twelve-month period may be increased by an amount not to exceed
(A) the cash proceeds from the sale of Equity Interests (other than Disqualified Stock) of the Issuer, in each case to members of management, directors or consultants of the Issuer, any of its Subsidiaries that occurs after the Issue Date;
provided that such cash proceeds utilized for redemptions, repurchases or other acquisitions or retirements will be excluded from clause (C)(II) of Section 4.09(a) plus (B) the cash proceeds of “key man” life insurance
policies received by the Issuer or its Restricted Subsidiaries after the Issue Date (provided that the Issuer may elect to apply all or any portion of the aggregate increase contemplated by clauses (A) and (B) above in any

clause (4)); 
 (5) repurchases, acquisitions or retirements of Capital Stock of the Issuer deemed to occur upon
the exercise or vesting of stock options, warrants or restricted stock or similar rights under employee benefit plans of the Issuer or its Subsidiaries if such Capital Stock represents all or a portion of the exercise price thereof or withholding
tax thereon; 
 (6) any Restricted Payments so long as the Total Debt Ratio is no more than 3.50 to 1.0 on a pro forma
basis after giving effect to such Restricted Payment as if such Restricted Payment had been made at the beginning of such twelve-month period most recently ended; 

(7) cash payments in lieu of the issuance of fractional shares in connection with the exercise of warrants, options or
other securities convertible into or exchangeable for Capital Stock of the Issuer; provided, however, that any such cash payment shall not be for the purpose of evading the limitation of this Section 4.09 (as determined in good faith by
the Board of Directors of the Issuer);

 (c) The amount of all Restricted Payments (other
than cash) will be the Fair Market Value on the date of the Restricted Payment of the assets, property or securities proposed to be transferred or issued by the Issuer or such Restricted Subsidiary, as the case may be, pursuant to the Restricted
Payment. If the Issuer or a Restricted Subsidiary of the Issuer makes a Restricted Payment which at the time of the making of such Restricted Payment would in the good faith determination of the Issuer 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 made in good faith to the Issuer’s financial statements affecting Consolidated Net Income of the
Issuer for any period. 

  
 45 

 (d) In the event that a Restricted Payment or Permitted Investment meets the criteria of more
than one of the types of Restricted Payments described in clauses (1) through (11) of Section 4.09(b) or Permitted Investments described in the definition thereof, the Issuer in its sole discretion may divide, classify or from time to time
reclassify all or any portion of such Restricted Payment or Permitted Investment in any manner that complies with this covenant and such Restricted Payment or Permitted Investment shall be treated as having been made pursuant only to the clause or
clauses of this covenant or of the definition of Permitted Investment to which such Restricted Payment or Permitted Investment has been classified or reclassified. 

Section 4.10 Liens. 

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or assume or
otherwise cause or suffer to exist or become effective any consensual Liens of any kind (other than Permitted Liens) against or upon any of their respective properties or assets, now owned or hereafter acquired, or any proceeds, income or profit
therefrom or assign or convey any right to receive income therefrom, to secure any Indebtedness of the Issuer unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured by a Lien on such property, assets, proceeds,
income or profit; provided, however, that if such Indebtedness is expressly subordinated to the Notes, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Notes with the same relative priority
as such Indebtedness has with respect to the Notes. 
 (b) Any Lien created for the benefit of the Holders of the Notes pursuant to
Section 4.10(a) shall provide by its terms that such Lien should be automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to the obligation to secure the Notes. 

(c) With respect to any Lien securing Indebtedness that was permitted under this Section 4.10 to secure such Indebtedness at the time of
the incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. 

Section 4.11 Asset Sales. 

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

(1) the Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale
at least equal to the Fair Market Value of the assets sold, leased, transferred, conveyed or otherwise disposed of or of the Equity Interests of any Restricted Subsidiary of the Issuer issued, sold, transferred, conveyed or otherwise disposed of as
determined in good faith by the Issuer’s management; and 
 (2) at least 75.0% of the consideration received in
the Asset Sale by the Issuer or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (2), each of the following will be deemed to be cash: 

(a) any liabilities, as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet prepared in
accordance with GAAP, of the Issuer or any of its Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee (or a third party on behalf of the
transferee) of any such assets whereby the Issuer or such Restricted Subsidiary is released from further liability whether specifically agreed by such transferee or third party or by operation of law; 

(b) any securities, notes or other obligations received by the Issuer or any such Restricted Subsidiary from such transferee
that are converted by the Issuer or such Restricted Subsidiary into cash or Cash Equivalents within 180 days, to the extent of the cash or Cash Equivalents received in that conversion; and 

  
 46 

 (c) any Designated Non-cash Consideration
received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this
clause (c) not to exceed 5.0% of the Consolidated Total Assets as of the end of the most recently ended fiscal quarter for which internal financial statements are available prior to the date on which such Designated Non-cash Consideration is received (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect
to subsequent changes in value) shall be deemed to be cash for purposes of this Section 4.11(2) and for no other purpose. 
 To the
extent that the Fair Market Value of any Asset Sale exceeds 10.0% of Consolidated Total Assets as of the end of the most recently ended fiscal quarter for which internal financial statements are available prior to the date on which such Net Proceeds
are received (with the Fair Market Value of each Asset Sale being measured at the time of such Asset Sale), then, within 365 days after the receipt of any Net Proceeds from any such Asset Sale (the “Asset Sale Proceeds Application
Period”), the Issuer or such Restricted Subsidiary may apply those Net Proceeds (but shall only be required to apply that portion of the Net Proceeds from such Asset Sale that exceeds 10.0% of Consolidated Total Assets) at its option
(or any portion thereof): 
 (1) to permanently repay Senior Debt of the Issuer (other than Indebtedness owed to the Issuer
or any Affiliate of the Issuer) and, if the Senior Debt repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto; 

(2) to acquire all or substantially all of the assets of, or all of the Capital Stock of, another Person engaged in a Permitted
Business; or 
 (3) to acquire other long-term assets or property that are used in a Permitted Business; 

provided that a binding commitment to apply Net Proceeds as set forth in clauses (1), (2) and (3) above shall be treated as a permitted
application of the Net Proceeds from the date of such commitment so long as the Issuer or such Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within
365 days of such commitment (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, then the Issuer
or such Restricted Subsidiary shall be permitted to apply the Net Proceeds in any manner set forth in clauses (1), (2) and (3) above before the expiration of such 365-day period from the date of such
Acceptable Commitment, and, in the event the Issuer or such Restricted Subsidiary fails to do so, such Net Proceeds shall constitute Excess Proceeds. Pending the final application of any Net Proceeds, the Issuer may temporarily reduce revolving
credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 
 Any Net Proceeds from
Asset Sales that were required to be applied in accordance with the first sentence of the immediately preceding paragraph and that are not so applied or invested as provided in the preceding paragraph will constitute “Excess
Proceeds.” When the aggregate amount of Excess Proceeds exceeds $150.0 million, within 30 days thereof, the Issuer will make an offer (an “Asset Sale Offer”) to all Holders to purchase the
maximum principal amount of Notes and, if the Issuer is required to do so under the terms of any other Indebtedness that is pari passu with the Notes, such other Indebtedness on a pro rata basis with the Notes, that may be purchased out of
the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100.0% of principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. The Issuer may satisfy the foregoing obligations
in this Section 4.11 with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer prior to the expiration of the Asset Sale Proceeds Application Period (an “Advance Offer”) with respect to all or
part of the available Net Proceeds from Asset Sales (the “Advance Portion”) in advance of being required to do so by this Indenture. 

If any Excess Proceeds (or, in the case of an Advance Offer, any of the Advance Portion) remain after consummation of the purchase of all
validly tendered and not withdrawn Notes pursuant to an Asset Sale Offer, the Issuer may use such remaining Excess Proceeds or Advance Portion, as the case may be, for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds or, in the case of an Advance Offer, the amount of the Advance Portion, the Trustee will select the Notes
and such other pari passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and pari passu Indebtedness; provided, however, that no Notes or other
pari passu Indebtedness will be selected and purchased in an unauthorized denomination. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. Upon completion of an Advance Offer, the
Advance Portion shall be excluded in subsequent calculations of the amount of Excess Proceeds. 

  
 47 

 The Issuer will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset
Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have
breached its obligations under this Section 4.11 or Section 3.08 by virtue of such compliance. 
 Section 4.12 Dividend
and Other Payment Restrictions Affecting Restricted Subsidiaries. 
 The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any of its Restricted Subsidiaries to: 

(a) pay dividends or make any other distributions on its Capital Stock to the Issuer or any of its Restricted Subsidiaries, or with respect to
any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Issuer or any of its Restricted Subsidiaries; 

(b) make loans or advances to the Issuer or any of its Restricted Subsidiaries; or 

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

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of: 

(1) agreements governing Existing Indebtedness and Credit Facilities (including the Revolving Credit Facility) and other
contractual encumbrances or restrictions as in effect on the Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements; provided that the
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive (as determined in good faith by the Board of Directors or senior management of the Issuer), taken as a whole,
with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date; 

(2) this Indenture and the Notes; 

(3) applicable law, rule, regulation or order of, or arrangement with, any regulatory body or agency including under contracts
with domestic or foreign governments or agencies thereof entered into in the ordinary course of business or consistent with past practice; 

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Issuer or any of its Restricted
Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted to be incurred by the terms of this
Indenture; 
 (5) restrictions on cash or other deposits or net worth imposed by customers or governmental regulatory bodies
or required by insurance, surety or bonding companies, in each case pursuant to contracts entered into in the ordinary course of business of the Issuer and its Restricted Subsidiaries; 

(6) customary non-assignment provisions in leases and other contracts entered into in
the ordinary course of business and consistent with industry practices; 
 (7) purchase money obligations for property
acquired in the ordinary course of business that impose restrictions on the property so acquired of the nature described in clause (c) of the preceding paragraph of this Section 4.12; 

  
 48 

 (8) any agreement for the direct or indirect sale or other disposition of a
Restricted Subsidiary of the Issuer or the assets of a Restricted Subsidiary of the Issuer that restricts distributions by such Restricted Subsidiary pending its sale or other disposition or the sale or other disposition of its assets; 

(9) Permitted Refinancing Indebtedness; provided, however, that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced (as determined in good faith by the Board of Directors or
senior management of the Issuer); 
 (10) Liens securing Indebtedness otherwise permitted to be incurred under the provisions
of Section 4.10 that limit the right of the debtor to dispose of the assets subject to such Liens; 
 (11) provisions
with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business, which encumbrance or
restriction is applicable only to the assets or property that are the subject of such agreements; 
 (12) any encumbrance or
restriction arising pursuant to an agreement or instrument relating to any Indebtedness, preferred stock or Disqualified Stock permitted to be incurred or issued under Section 4.08 provided, however, that the incurrence of such
Indebtedness or the issuance of such preferred stock or Disqualified Stock that the encumbrances or restrictions contained in any such agreement or instrument, taken as a whole, either (a) are not materially less favorable to the Holders of the
Notes than the encumbrances and restrictions contained in the Revolving Credit Facility (as determined in good faith by the Board of Directors or senior management of the Issuer) or (b) will not adversely affect, in any material respect, the
Issuer’s ability to pay the Obligations under this Indenture when due (as determined in good faith by the Board of Directors or senior management of the Issuer); 

(13) any encumbrance or restriction arising pursuant to an agreement or instrument relating to any Indebtedness, preferred
stock or Disqualified Stock permitted to be incurred or issued by Foreign Restricted Subsidiaries under Section 4.08; provided, however, that such agreement or instrument imposes restrictions and encumbrances solely on the Foreign
Restricted Subsidiaries party thereto; and 
 (14) any encumbrance or restriction on any Restricted Subsidiary organized in
jurisdictions, states or other political subdivisions thereof where such encumbrances or restrictions are customary. 
 (d) For purposes of
determining compliance with this covenant, (1) 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 and (2) the subordination of (including the application of any standstill requirements) loans and advances made to the Issuer or a Restricted Subsidiary of the Issuer to other Indebtedness
incurred by the Issuer or such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances. 

Section 4.13 Affiliate Transactions. 

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each,
an “Affiliate Transaction”) involving aggregate payments or consideration, taken together with any related Affiliated Transactions, in excess of $20.0 million, unless: 

(1) the Affiliate Transaction is on terms, taken as a whole, that are not materially less favorable to the Issuer or the
relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person; and 

(2) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $100.0 million, the Board of Directors of the Issuer has determined that such Affiliate Transaction complies with this Section 4.13 and that such Affiliate Transaction has been approved by a majority of the disinterested members
of the Board of Directors of the Issuer. 

  
 49 

 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not
be subject to this Section 4.13: 
 (1) transactions solely between or among the Issuer and/or any of its Restricted
Subsidiaries or solely among its Restricted Subsidiaries; 
 (2) issuances or sales of Equity Interests of the Issuer (other
than Disqualified Stock) to Affiliates of the Issuer; 
 (3) reasonable and customary directors’ fees, indemnification
and similar arrangements, consulting fees, employee salaries, bonuses or employment agreements, compensation or employee benefit arrangements and incentive arrangements with any officer, director, employee or consultant of the Issuer or a Restricted
Subsidiary of the Issuer entered into in the ordinary course of business; 
 (4) any payments or other transactions pursuant
to a Tax Sharing Agreement; 
 (5) any Restricted Payments, Permitted Investments or other transactions made in compliance
with Section 4.09; 
 (6) loans and advances to non-executive officers,
employees or consultants of the Issuer or any of its Restricted Subsidiaries in the ordinary course of business made in accordance with the past practices of the Issuer or any of its Restricted Subsidiaries; 

(7) any agreement as in effect on the Issue Date or any amendment thereto so long as any such amendment is not more
disadvantageous to the Holders in any material respect than the original agreement as in effect on the Issue Date; 
 (8)
sales or other dispositions of accounts receivable or licensing royalties and related assets to a Securitization Subsidiary in a Qualified Securitization Transaction; provided that such accounts receivable or licensing royalties are
customarily transferred in such a transaction; 
 (9) any employment agreements, consultant agreements or employee benefit
arrangements with any employee, consultant, officer or director of the Issuer or any of its Restricted Subsidiaries, including under any stock option, stock appreciation right, stock incentive or similar plan, entered into in the ordinary course of
business, and the transactions pursuant thereto; 
 (10) any transaction effected as part of a Qualified Securitization
Transaction; 
 (11) transactions entered into by a Person prior to the time such Person becomes a Restricted Subsidiary of
the Issuer or is merged or consolidated into the Issuer or a Restricted Subsidiary of the Issuer; provided that such transaction is not entered into in contemplation of such event; 

(12) transactions in which the Issuer or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a
letter from an Independent Financial Advisor stating that such transaction is fair to the Issuer or such Restricted Subsidiary from a financial point of view or stating that the terms are not materially less favorable to the Issuer or its relevant
Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person on an arm’s length basis; 

(13) (a) transactions with customers, clients, suppliers, landlords, lessors, or purchasers or sellers of goods or services, in
each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture that are fair to the Issuer, or are on terms at least as favorable as would reasonably have been entered into at such time with an unaffiliated
party (as determined in good faith by the Board of Directors or senior management of the Issuer) and (b) transactions with joint ventures or Unrestricted Subsidiaries entered into in the ordinary course of business; 

  
 50 

 (14) transactions with a Person that is an Affiliate of the Issuer solely because
the Issuer, directly or indirectly, owns Equity Interests in such Person; 
 (15) transactions with an Affiliate of the
Issuer where the only consideration paid by the Issuer or any Restricted Subsidiary of the Issuer is Capital Stock of the Issuer (other than Disqualified Stock); 

(16) Guarantees permitted to be incurred or issued under Section 4.08; 

(17) intercompany transactions undertaken for the purpose of improving the consolidated tax efficiency of the Issuer and its
Subsidiaries and not for the purpose of circumventing any covenant set forth in this Indenture as determined by the Board of Directors or senior management of the Issuer in good faith; and 

(18) the Transactions. 

Section 4.14 Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Issuer’s Board of Directors may designate any of its Restricted Subsidiaries to be an Unrestricted Subsidiary if that designation
would not cause a Default and if that designation otherwise is consistent with the definition of an Unrestricted Subsidiary. If any of the Restricted Subsidiaries of the Issuer is designated as an Unrestricted Subsidiary, the aggregate Fair Market
Value of all outstanding Investments owned by the Issuer and its Restricted Subsidiaries in the newly designated Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of that designation and will reduce the amount available
for Restricted Payments under Section 4.09(a) or Permitted Investments, as determined by the Issuer. The designation of such a Subsidiary or Person as an Unrestricted Subsidiary will be permitted only if the Investment would be permitted at the
time the Restricted Subsidiary is designated as an Unrestricted Subsidiary and, in any case, if that Subsidiary or Person otherwise satisfies the requirements set forth in the definition of Unrestricted Subsidiary. 

(b) Any designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a
certified copy of a Board Resolution of the Issuer giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted under the provisions of
Section 4.09. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any
Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Issuer as of such date and, if such Indebtedness is not permitted to be incurred as of such date under the provisions of Section 4.08 the Issuer
will be in Default. The Board of Directors of the Issuer may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Issuer; provided that such designation will be deemed to be an incurrence of Indebtedness by a
Restricted Subsidiary of the Issuer of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.08, calculated on a pro forma basis as if
such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation. 

(c) Any Subsidiary of an Unrestricted Subsidiary shall also be deemed an Unrestricted Subsidiary. 

(d) For the avoidance of doubt, the Escrow Issuer shall be deemed an Unrestricted Subsidiary prior to the Assumption Date. Prior to the
Assumption Date, the Escrow Issuer shall be subject to Section 4.19. 
 Section 4.15 Repurchase at the Option of Holders Upon a
Change of Control. 
 (a) Upon the occurrence of a Change of Control, the Issuer shall, within 30 days following the date upon which a
Change of Control occurred, make an offer (the “Change of Control Offer”) pursuant to the procedures set forth in Section 3.08. Each Holder shall have the right to accept such offer and require the Issuer to repurchase
all or any portion (equal to $2,000 or an integral multiple of $1,000) of such Holder’s Notes pursuant to the Change of Control Offer at a purchase price, in cash (the “Change of Control Amount”), equal to 101.0% of the
aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased, to, but excluding, the Purchase Date (subject to the right of Holders of record on the relevant record date to receive interest due
on an interest payment date falling prior to the Purchase Date). 

  
 51 

 (b) The Issuer will not be required to make a Change of Control Offer upon a Change of Control if
(i) 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 the Issuer and purchases all Notes validly tendered and not withdrawn
under the Change of Control Offer or (ii) a notice of redemption of all outstanding Notes has been given pursuant to this Indenture as provided in Section 3.03, unless and until there is a Default in the payment of the Redemption Price on
the applicable Redemption Date or the redemption is not consummated due to the failure of a condition precedent contained in the applicable redemption notice to be satisfied. A Change of Control Offer may be made in advance of a Change of Control
and may be conditional upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 

Section 4.16 Limitation on Issuances of Guarantees of Indebtedness. 

(a) The Issuer will not permit any of its Restricted Subsidiaries, directly or indirectly, to Guarantee or pledge any assets to secure the
payment of any other Indebtedness of the Issuer unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture providing for the Guarantee of the payment of the Notes by such Restricted Subsidiary. The Subsidiary
Guarantee will be (1) senior to such Restricted Subsidiary’s Guarantee of or pledge to secure such other Indebtedness if such other Indebtedness is subordinated to the Notes; or (2) pari passu with such Restricted
Subsidiary’s Guarantee of or pledge to secure such other Indebtedness if such other Indebtedness is not subordinated to the Notes. 

(b) The Subsidiary Guarantee of a Guarantor will be automatically and unconditionally released: 

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by
way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Subsidiary of the Issuer, if the sale or other disposition is permitted under Section 4.11; 

(2) in connection with any sale or other disposition of all of the Capital Stock of that Guarantor to a Person that is not
(either before or after giving effect to such transaction) the Issuer or a Subsidiary of the Issuer, if the sale or other disposition does not violate the provisions of this Indenture, including Section 4.11; and such Guarantor ceases to be a
Restricted Subsidiary as a result of such sale or other disposition; 
 (3) if the Issuer designates any of its Restricted
Subsidiaries that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; 

(4) upon legal defeasance, covenant defeasance or satisfaction and discharge of the Notes as provided under Sections 8.02,
8.03 and 11.01; or 
 (5) if such Guarantor is released from the underlying Guarantee of Indebtedness giving rise to the
execution of a Subsidiary Guarantee. 
 (c) The form of Subsidiary Guarantee is attached hereto as Exhibit B and the related form of
supplemental indenture is attached hereto as Exhibit D. Notwithstanding the foregoing terms of this Section 4.16, if the Issuer guarantees Indebtedness incurred by any of its Restricted Subsidiaries, such Guarantee by
the Issuer will not require any of its Restricted Subsidiaries to provide a Subsidiary Guarantee for the Notes. 
 Section 4.17
Covenant Termination. 
 Following the first day after the Assumption Date: 

(a) the Notes have an Investment Grade Rating; and 

(b) no Default has occurred and is continuing under this Indenture; 

the Issuer and its Restricted Subsidiaries shall cease to be subject to the provisions of: 

(1) Section 4.08; 

  
 52 

 (2) Section 4.09; 

(3) Section 4.11 

(4) Section 4.12; 

(5) Section 4.13; and 

(6) Section 4.16 

(collectively, the “Terminated Covenants”). No Default, Event of Default or breach of any kind shall be deemed to exist under this
Indenture or the Notes with respect to the Terminated Covenants based on, and none of the Issuer or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring after the Notes attain an Investment Grade Rating,
regardless of whether such actions or event would have been permitted if the applicable Terminated Covenants remained in effect. The Terminated Covenants will not be reinstated even if the Issuer subsequently does not satisfy the requirements set
forth in clauses (a) and (b) of this Section 4.17. After the Terminated Covenants have been terminated, the Issuer and its Restricted Subsidiaries shall remain subject to the provisions of Section 4.15 and the following Sections: 

(1) Section 4.03; 

(2) Section 4.10; and 

(3) Section 5.01 (other than the financial test set forth in clause (a)(4) thereof). 

Section 4.18 Escrow Agreement. 

(a) Concurrently with the issuance of the Initial Notes on the Issue Date, the Escrow Issuer shall enter into the Escrow Agreement, pursuant to
which the Escrow Issuer will deposit or cause to be deposited in an escrow account (the “Escrow Account”) with the Escrow Agent (i) an amount in cash equal to the gross proceeds of the offering of the Initial Notes
issued on the Issue Date and (ii) an additional amount in cash (collectively, with any other property from time to time held by the Escrow Agent for the benefit of the Holders, the “Escrowed Property”) that, when taken
together with the gross proceeds deposited into the Escrow Account, will be sufficient to fund a Special Mandatory Redemption of the Initial Notes on May 31, 2018, if a Special Mandatory Redemption were to occur on such date, plus an amount
equal to five days of interest accrued on the Initial Notes. In addition, pursuant to the Escrow Agreement, on or prior to the date that is five Business Days prior to the last day of each month, from and including May 2018 through and including
August 2018 (in each case, unless the Escrowed Property has been released in accordance with the terms of the Escrow Agreement (such release, the “Escrow Release”), the Issuer will deposit or cause to be deposited into the
Escrow Account an amount of cash equal to the amount of interest that will accrue on the Initial Notes from (and including) the first day of the following month through (and including) the last day of such following month. 

(b) From the Issue Date until the Escrow Release, the Trustee shall, for the benefit of the Trustee and the Holders of the Notes, be granted a
security interest in the Escrow Issuer’s right in the Escrowed Property pursuant to Section 15 of the Escrow Agreement. Upon the Escrow Release, such security interest of the Trustee on the Escrowed Property shall be automatically
extinguished. 
 (c) From the Issuer Date until the Release, the Escrowed Property shall be invested by the Escrow Agent in Cash Equivalents
as set forth in the Escrow Agreement. 
 (d) The Issuer shall only be entitled to direct the Escrow Agent to release the Escrowed Property
upon satisfaction of the conditions set forth in the Escrow Agreement, which shall be certified in writing by the Issuer in an Officers’ Certificate delivered to the Trustee and the Escrow Agent contemporaneously with the release of any
Escrowed Property. 

  
 53 

 Section 4.19 Limitations on Activities Prior to the Escrow Merger. 

(a) Prior to the Escrow Merger, the Escrow Issuer shall remain a wholly-owned Subsidiary of the Company and shall limit its activities to
(i) issuing the Initial Notes, (ii) performing its obligations under this Indenture, the Purchase Agreement and the Escrow Agreement (including the granting of a security interest on the Escrowed Property), (iii) instructing the Escrow
Agent with respect to the investment of the Escrowed Property in accordance with the terms of the Escrow Agreement, (iv) consummating the Escrow Merger, (v) redeeming the Notes on the Special Mandatory Redemption Date, if applicable and
(vi) conducting such other activities as are necessary or appropriate to carry out the activities described in this Section 4.19. Prior to the Escrow Merger, the Escrow Issuer will not own, hold or otherwise have any interest in any assets
other than the Escrowed Property. The Escrow Issuer shall not engage in any business operations or other activities, notwithstanding anything to the contrary contained in this Indenture, including incurring Indebtedness, issuing Disqualified Stock,
making Restricted Payments, consummating Asset Sales, entering into Affiliate Transactions, incurring or permitting to exist any Lien on any of its properties, other than those contemplated by this Section 4.19(a).

consummated any Asset Sales, entered into any Affiliate Transactions, incurred or permitted to exist any Lien on any of its properties, or otherwise taken any action or engaged in any activities during the period beginning on the Issue Date and
ending on the Assumption Date, such actions and activities shall be treated and classified under this Indenture as if this Indenture and the covenants set forth herein had applied to the Company and its Restricted Subsidiaries during such period,
except for any covenant which, by its terms, is incapable of being complied with by the Company or any of its Restricted Subsidiaries prior to the Assumption Date.

Indenture; 
 (2) the Surviving Entity expressly assumes, pursuant to agreements reasonably satisfactory to the
Trustee, all the Obligations of the Issuer under the Notes and this Indenture;

Issuer on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties or assets of the Issuer. 

Section 5.02 Successor Corporation Substituted. 

The Surviving Entity shall succeed to, and be substituted for, and may exercise every right and power of the Issuer or a Guarantor, as

and the Trustee upon the request of Holders of 25.0% in aggregate principal amount of the outstanding Notes shall, or the Holders of at least 25.0% in aggregate principal amount of outstanding Notes may, declare the principal, premium, if any, and
accrued and unpaid interest, if any, of all the outstanding Notes, to be due and payable by notice in writing to the Issuer and the Trustee specifying the respective Event of Default and that such notice is a notice of acceleration (the
“Acceleration Notice”), and the same shall become immediately due and payable. 
 In the case of an Event of Default
specified in Section 6.01(i) or (j) the principal, premium, if any, and accrued and unpaid interest, if any, of all of the outstanding Notes shall become due and payable immediately without any further action or notice on the part of the
Trustee or the Holders. Holders may not enforce this Indenture or the Notes except as provided in this Indenture. 
 Section 6.03
Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of
principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The
Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default
shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies shall be cumulative to the extent permitted by law. 

Section 6.04 Waiver of Defaults. 

(a) The Holders of at least a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of

and (B) in respect of a covenant or provision which under this Indenture cannot be modified or amended without the consent of the Holder of each Note affected by such modification or amendment and (ii) rescind any acceleration and its
consequences with respect to the Notes. 
 (b) Upon any waiver of a Default or Event of Default, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed cured for every purpose of this Indenture but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 6.05 Control by Majority. 

Subject to Sections 7.01, 7.02(f) (including the Trustee’s receipt of the security or indemnification described therein) and 7.07
hereof, in case an Event of Default shall occur and be continuing, the Holders of a majority in aggregate principal amount of the Notes then outstanding shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes. 
 Section 6.06
Limitation on Suits. 
 No Holder shall have any right to institute any proceeding with respect to this Indenture, or for the appointment
of a receiver or trustee, or for any remedy hereunder, unless: 
 (a) such Holder has previously given to the Trustee written notice of a
continuing Event of Default or the Trustee receives the notice from the Issuer; 
 (b) Holders of at least 25.0% in aggregate principal
amount of the Notes then outstanding have made written request and offered indemnity to the Trustee reasonably satisfactory to it to institute such proceeding as Trustee; and 

  
 57 

 (c) the Trustee shall not have received from the Holders of a majority in aggregate principal
amount of the Notes then outstanding a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. 

The preceding limitations shall not apply to a suit instituted by a Holder for enforcement of payment of principal of, and premium, if any, or
interest on, a Note on or after the respective due dates for such payments set forth in such Note. 
 Section 6.07 Rights of Holders
to Receive Payment. 
 Notwithstanding any other provision of this Indenture (including Section 6.06), the right of any Holder to
receive payment of principal, premium, if any, and interest on the Notes held by such Holder, on or after the respective due dates expressed in the Notes (including in connection with an Offer to Purchase), or to bring suit for the enforcement of
any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

Section 6.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in
its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium, if any, and interest then due and owing (together with interest on overdue principal and, to the extent lawful, interest) and such
further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim. 

The Trustee shall be authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have
the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other
obligor upon the Notes), its assets or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee and its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, moneys, securities and any other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise.
Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any
Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10

 If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation,
expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

  
 58 

 Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any,
and interest ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 

Third: to the Issuer or to such party as a court of competent jurisdiction shall direct in writing. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 

Section 6.11 Undertaking for Costs.

by it as a Trustee, a court in its discretion may require the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 shall not apply to a suit by the Trustee, a suit
by the Issuer, a suit by a Holder pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

 Section 7.01 Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this

privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including without

risk or liability is not assured to it. 
 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 Issuer or any
Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like
rights and duties. The Trustee shall also be subject to Sections 7.10 and 7.11 hereof. 
 Section 7.04 Trustee’s
Disclaimer.

 Section 7.05 Notice of Defaults. 

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

Section 7.06 Reports by Trustee to Holders. 

Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the
Trustee shall send to the Holders a brief report dated as of such reporting date that complies with TIA §313(a) (but if no event described in TIA §313(a) has occurred within one year preceding the reporting date, no report need be
transmitted), if so required by TIA §313(a). The Trustee also shall comply with TIA §313(b)(2). The Trustee shall also send all reports as required by TIA §313(c). 

A copy of each report at the time of its sending to the Holders shall be sent to the Issuer and filed with the SEC and each stock exchange on
which the Notes are listed in accordance with TIA §313(d). The Issuer shall promptly notify the Trustee when the Notes are listed on any stock exchange and any delisting thereof. 

Section 7.07 Compensation and Indemnity. 

The Issuer shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it
in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

  
 61 

 The Issuer, and the Guarantors, if any, shall, jointly and severally, indemnify the Trustee, its
directors, officers, employees or agents or any predecessor Trustee against any and all losses, claims, damages, penalties, fines, liabilities or expenses, including incidental and
out-of-pocket expenses and reasonable attorneys’ fees and expenses (for purposes of this Section 7.07, “losses”) incurred by it arising
out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer (including this Section 7.07) and defending itself against any
claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent such losses have been determined to have been caused
by its own gross negligence or willful misconduct. The Trustee shall notify the Issuer promptly of any claim of which a Responsible Officer has received written notice and for which it may seek indemnity. Failure by the Trustee to so notify the
Issuer shall not relieve the Issuer of its obligations under this Section 7.07. The Issuer shall defend the claim, and the Trustee shall cooperate in the defense. The Trustee may have separate counsel if the Trustee has been reasonably advised
by counsel that there may be one or more legal defenses available to it that are different from or additional to those available to the Issuer and in the reasonable judgment of such counsel it is advisable for the Trustee to engage separate counsel,
and the Issuer shall pay the reasonable fees and expenses of such counsel. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The Issuer need not reimburse any expense or indemnify
against any loss incurred by the Trustee through the Trustee’s own willful misconduct or gross negligence. 
 The obligations of the
Issuer and the Guarantors, if any, under this Section 7.07 shall survive the satisfaction and discharge of this Indenture, the resignation or removal of the Trustee and payment in full of the Notes. 

To secure the Issuer’s and Guarantors’, if any, payment obligations in this Section 7.07, the Trustee shall have a Lien prior
to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. 

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

Section 7.08 Replacement of Trustee. 

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.08. 
 The Trustee may resign in writing at any time upon 30 days’ prior
notice to the Issuer and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer
in writing. The Issuer may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10 hereof; 

(b) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 

(c) a custodian or public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Issuer shall promptly appoint a successor Trustee. 
 Within one year after the successor Trustee
takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. 

  
 62 

 If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or
is removed, the retiring Trustee, the Issuer, or the Holders of at least 10.0% in aggregate principal amount of the then outstanding Notes may, at the expense of the Issuer, petition any court of competent jurisdiction for the appointment of a
successor Trustee. 
 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply
with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer and enter into a
supplemental indenture with the retiring Trustee and the Issuer in which it assumes the rights, powers and duties of the Trustee under this Indenture. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders. Subject to the Lien provided for in Section 7.07 hereof, the
retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided, however, that all sums owing to the Trustee hereunder shall have been paid. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 

In the case of an appointment hereunder of a separate or successor Trustee with respect to the Notes, the Issuer, any retiring Trustee and
each successor or separate Trustee with respect to the Notes shall execute and deliver a supplemental indenture hereto (1) which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of any retiring Trustee with respect to the Notes have been assumed by a successor Trustee and in the case where any retiring Trustee is retiring only with respect to some of the Notes that the rights, powers, trusts and duties of
any retiring Trustee with respect to the Notes as to which any such retiring Trustee is not retiring shall continue to be vested in such retiring Trustee and (2) that shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustee
co-trustees of the same trust and that each such separate, retiring or successor Trustee shall be Trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by
any such other Trustee. 
 Section 7.09 Successor Trustee by Merger, etc. 

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation or banking association, the successor corporation or banking association without any further act shall, if such successor corporation or banking association is otherwise eligible hereunder, be the successor Trustee. 

Section 7.10 Eligibility; Disqualification. 

There shall at all times be a Trustee hereunder that is a Person organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50.0 million (or
a wholly-owned subsidiary of a bank or trust company, or of a bank holding company, the principal subsidiary of which is a bank or trust company having a combined capital and surplus of at least $50.0 million) as set forth in its most recent
published annual report of condition. 
 This Indenture shall always have a Trustee who satisfies the requirements of TIA §310(a)(1).

 Section 7.11 [Reserved] 

Section 7.12 Escrow Agreement. 

The Trustee is hereby directed to agree to the appointment of the Escrow Agent and is hereby directed to enter into the Escrow Agreement. The
Trustee is not responsible for the contents or sufficiency of the Escrow Agreement; and in entering into the Escrow Agreement, and with respect to all matters arising under the Escrow 

  
 63 

 
Agreement, the Trustee shall have the rights, protections, immunities and indemnities granted to it under this Indenture. Neither the Trustee nor any Holder (whether acting directly or by
direction or demand to the Trustee) shall be entitled or permitted to give any direction to, or make any demand upon, the Escrow Agent that would be contrary to, or in conflict with, the provisions governing the Escrow Release in accordance with the
Escrow Agreement, or as otherwise expressly set forth hereto or thereto. 
 ARTICLE 8. 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Issuer may, at its option and at any time, elect to have either Sections 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth in this Article 8. Any such election shall be evidenced by a Board Resolution set forth in an Officers’ Certificate. 

Section 8.02 Legal Defeasance and Discharge. 

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.02, the Issuer shall, subject to the
satisfaction of the conditions set forth in Section 8.04, be deemed to have been discharged from its Obligations with respect to all outstanding Notes on the date the conditions set forth in Section 8.04 are satisfied (hereinafter,
“Legal Defeasance”) and each Guarantor, if any, shall be released from all of its obligations under its Subsidiary Guarantee. For this purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in (a) and
(b) of this Section 8.02, and to have satisfied all its other Obligations under the Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except
for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04, and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any, or interest on such Notes when such payments are due, (b) the Issuer’s Obligations with respect to such Notes under Article 2 and Sections 4.01 and
4.02, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s and the Guarantor’s, if any, Obligations in connection therewith and (d) this Article 8. If the Issuer exercises under
Section 8.01 the option applicable to this Section 8.02, subject to the satisfaction of the conditions set forth in Section 8.04, payment of the Notes may not be accelerated because of an Event of Default. Subject to compliance with
this Article 8, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03. 

Section 8.03 Covenant Defeasance. 

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuer shall, subject to the
satisfaction of the conditions set forth in Section 8.04, be released from its Obligations under the covenants contained in Sections 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15 and 4.16 hereof, and the operation of Section 5.01(a)(4)),
with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”) and each Guarantor, if any, shall be released from all of its
Obligations under its Subsidiary Guarantee with respect to such covenants in connection with such outstanding Notes and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed
outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth
in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above in this Section 8.03, the remainder of this Indenture and such Notes shall be unaffected thereby. If the Issuer exercises under
Section 8.01 the option 

  
 64 

 
applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, payment of the Notes may not be accelerated because of an Event of Default
specified in clause (c) (with respect to the covenant contained in Section 5.01(a)(4) hereof), clause (d) (with respect to the covenants contained in Section 4.08, 4.09, 4.11 and 4.15 hereof), clause (f) (with respect to the covenants
contained in Sections 4.10, 4.12, 4.13 and 4.16 hereof), and clauses (g), (h), (i) and (j) (but in the case of (i) and (j) of Section 6.01, with respect to Significant Subsidiaries only) of Section 6.01. 

Section 8.04 Conditions to Legal or Covenant Defeasance. 

The following shall be the conditions to the application of either Section 8.02 or 8.03 to the outstanding Notes. 

The Legal Defeasance or Covenant Defeasance may be exercised only if: 

(a) the Issuer irrevocably deposits with the Trustee, in trust (the “defeasance trust”), for the benefit of the
Holders, cash in Dollars, non-callable Government Securities, or a combination of cash in Dollars and non-callable Government Securities, in amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public accountants (a copy of which shall be provided to the Trustee), to pay the principal, premium, if any, and interest on the outstanding Notes on the Stated Maturity or
on the next Redemption Date, as the case may be, and the Issuer shall specify whether the Notes are being defeased to maturity or to such particular Redemption Date; 

(b) in the case of Legal Defeasance, the Issuer shall deliver to the Trustee an Opinion of Counsel confirming that (i) the Issuer has
received from, or there has been published by, the Internal Revenue Service a ruling or (ii) subsequent to the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon
such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such 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 Legal Defeasance had not occurred; 
 (c) in the case
of Covenant Defeasance, the Issuer shall deliver to the Trustee an Opinion of Counsel 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; 

(d) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to make such deposit and the grant of any Lien securing such borrowing); 
 (e) such
Legal Defeasance or Covenant Defeasance shall 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 Issuer or any of its Subsidiaries is a party or by
which the Issuer or any of its Subsidiaries are bound; 
 (f) the Issuer shall deliver to the Trustee an Officers’ Certificate stating
that the deposit was not made by the Issuer with the intent of preferring the Holders over other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding such other creditors; and 

(g) the Issuer delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05 Deposited Cash and Government
Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06, all cash and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the
“Trustee”) pursuant to Section 8.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in  

  
 65 

 
accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as
the Trustee may determine, to the Holders of all sums due and to become due thereon in respect of principal, premium, if any, and interest but such cash and securities need not be segregated from other funds except to the extent required by law.

 The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof 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 8 to the contrary notwithstanding, the Trustee shall
deliver or pay to the Issuer from time to time upon the request of the Issuer any cash or non-callable Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally
recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Trustee (which may be the certification delivered under Section 8.04(a)), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to
Issuer. 
 The Trustee shall promptly, and in any event, no later than five (5) Business Days, pay to the Issuer after request
therefor, any excess money held with respect to the Notes at such time in excess of amounts required to pay any of the Issuer’s Obligations then owing with respect to the Notes. 

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

Section 8.07 Reinstatement. 

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

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

Notwithstanding Section 9.02 of this Indenture, the Issuer and the Trustee may amend or supplement this Indenture or the Notes without
notice to or the consent of any Holder to: 
 (1) to cure any ambiguity, omission, mistake, defect, error or
inconsistency; 

  
 66 

 (2) to provide for uncertificated Notes in addition to or in place of
certificated Notes; 
 (3) to provide for the assumption of the Issuer’s obligations to Holders of Notes in the
case of a merger or consolidation or sale of all or substantially all of the Issuer’s assets or any other transaction that complies with this Indenture; 

(4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that the Issuer
determines in good faith (as certified in an Officers’ Certificate) does not materially and adversely affect the legal rights under this Indenture of any such Holder; 

(5) to provide for the issuance of Additional Notes in accordance with this Indenture; or 

(6) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the
Trust Indenture Act; 
 (7) to allow any Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee
with respect to the Notes; 
 (8) to evidence and provide the acceptance of the appointment of a successor trustee
under this Indenture; 
 (9) to mortgage, pledge, hypothecate or grant a security interest in favor of the trustee for
the benefit of the Holders as additional security for the payment and performance of the Issuer’s or a Guarantor’s Obligations under this Indenture in property or assets; 

(10) to comply with the rules of any applicable Depositary; 

(11) to release a Guarantor from its Subsidiary Guarantee pursuant to the terms of this Indenture when permitted or
required pursuant to the terms herein; 
 (12) to conform the text of this Indenture, the Notes or the Subsidiary
Guarantees to the corresponding provision of the “Description of Notes” in the Offering Memorandum to the extent that such provision in the “Description of Notes” was intended to be a substantially verbatim recitation of a
provision of this Indenture, the Notes or the Subsidiary Guarantees; or 
 (13) to comply with Section 5.01. 

Section 9.02 With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Issuer and the Trustee may amend or supplement this Indenture and the Notes with the
consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of or tender offer or exchange offer
for the Notes), and, subject to Sections 6.04 and 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of at least a majority in aggregate
principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of or tender offer or exchange offer for the Notes). 

Without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of Notes whose Holders
must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the Stated Maturity of
any Note or alter the provisions with respect to the redemption or repurchase of any Note (other than provisions relating to Section 4.15 (and any applicable definitions)); 

  
 67 

 (3) reduce the rate of or change the time for payment of interest on any
Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on
the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the Payment Default that resulted from such acceleration); 

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

(6) make any change in the provisions (including applicable definitions) of this Indenture relating to waivers of past
Defaults or the rights of Holders of Notes to receive payments of principal of, or interest or premium, if any, on the Notes (other than provisions relating to Section 4.15 (and any applicable definitions)); 

(7) waive a redemption or repurchase payment with respect to any Note (other than a payment required by
Sections 4.11 or 4.15 hereof); 
 (8) make any material change in the provisions of Sections 3.09 or 4.18 of
this Indenture; 
 (9) make any change in the Escrow Agreement that would adversely affect the Holders in any material
respect; or 
 (10) make any change in the preceding amendment and waiver provisions. 

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any
supplemental indenture. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders
after such record date; provided that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 120 days after such record date, any such consent previously given
shall automatically and without further action by any Holder be cancelled and of no further effect. 
 It shall not be necessary for the
consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall send to the Holder of each Note
affected thereby to such Holder’s address appearing in the Note Register a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to send such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such amended or supplemental indenture or waiver. 
 Section 9.03 Revocation and Effect of
Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the
Holder of a Note and every subsequent Holder of a Note or portion thereof 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 its Note or portion thereof if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver shall become effective in accordance
with its terms and thereafter shall bind every Holder. 
 Section 9.04 Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in
exchange for all Notes may issue and, upon receipt of a Company Order in accordance with Section 2.02 hereof, the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 

  
 68 

 Failure to make the appropriate notation or issue a new Note shall not affect the validity and
effect of such amendment, supplement or waiver. 
 Section 9.05 Trustee to Sign Amendments, etc. 

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amendment or supplemental indenture until its Board of Directors (or committee serving a similar function) approves it. In executing any
amended or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.01 hereof) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such
amended or supplemental indenture is authorized or permitted by this Indenture and that such amended or supplemental indenture is the legal, valid and binding obligations of the Issuer enforceable against it in accordance with its terms, subject to
customary exceptions and that such amended or supplemental indenture complies with the provisions hereof. 
 ARTICLE 10. 

SUBSIDIARY GUARANTEES 

Section 10.01 Subsidiary Guarantee. 

Subject to this Article 10, any Guarantor that executes and delivers a supplemental indenture pursuant to this Indenture shall, upon
execution and delivery of its supplemental indenture, jointly and severally and unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns: (a) the due and
punctual payment of the principal of, premium, if any, and interest on the Notes, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise, the due and punctual payment of interest on the overdue
principal of and premium, if any, and, to the extent permitted by law, interest, and the due and punctual performance of all other obligations of the Issuer to the Holders or the Trustee under this Indenture and the Notes, all in accordance with the
terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension
or renewal, whether at Stated Maturity, by acceleration pursuant to Section 6.02, redemption or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be
jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

Each Guarantor hereby agrees that its obligations with regard to its Subsidiary Guarantee shall be joint and several, unconditional,
irrespective of the validity or enforceability of the Notes or the obligations of the Issuer under this Indenture, the absence of any action to enforce the same, the recovery of any judgment against the Issuer or any other obligor with respect to
this Indenture, the Notes or the Obligations of the Issuer under this Indenture or the Notes, any action to enforce the same or any other circumstances (other than complete performance) which might otherwise constitute a legal or equitable discharge
or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such claims, rights
or remedies, including but not limited to: (a) any right to require any of the Trustee, the Holders or the Issuer (each a “Benefited Party”), as a condition of payment or performance by such Guarantor, to
(1) proceed against the Issuer, any other guarantor (including any other Guarantor) of the Obligations under the Subsidiary Guarantees or any other Person, (2) proceed against or exhaust any security held from the Issuer, any such other
guarantor or any other Person, (3) proceed against or have resort to any balance of any deposit account or credit on the books of any Benefited Party in favor of the Issuer or any other Person, or (4) pursue any other remedy in the power
of any Benefited Party whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Issuer including any defense based on or arising out of the lack of validity or the
unenforceability of the Obligations under the Subsidiary Guarantees or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Issuer from any cause other than payment in full of the Obligations
under the Subsidiary Guarantees; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal;
(d) any defense based upon any 

  
 69 

 
Benefited Party’s errors or omissions in the administration of the Obligations under the Subsidiary Guarantees, except behavior which amounts to bad faith; (e)(1) any principles or
provisions of law, statutory or otherwise, which are or might be in conflict with the terms of the Subsidiary Guarantees and any legal or equitable discharge of such Guarantor’s obligations hereunder, (2) the benefit of any statute of
limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (3) any rights to set-offs, recoupments and counterclaims and (4) promptness, diligence and any requirement
that any Benefited Party protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of any action or
inaction, including acceptance of the Subsidiary Guarantees, notices of Default under the Notes or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Obligations under the Subsidiary Guarantees or
any agreement related thereto, and notices of any extension of credit to the Issuer and any right to consent to any thereof; (g) to the extent permitted under applicable law, the benefits of any “One Action” rule and (h) any
defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Subsidiary Guarantees. Except to the extent expressly provided herein,
including Sections 8.02, 8.03 and 10.05, each Guarantor hereby covenants that its Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained in its Subsidiary Guarantee and this Indenture. 

If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect. 
 Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect
of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Section 6.02 for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby and (y) in the event of any declaration of acceleration of such obligations as provided in Section 6.02, such obligations (whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights
of the Holders under the Subsidiary Guarantee. 
 Section 10.02 Limitation on Guarantor Liability. 

(a) Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the
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 guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that each Guarantor’s liability shall be that amount from time to time equal to the aggregate liability of such Guarantor
under the guarantee, but shall be limited to the lesser of (x) the aggregate amount of the Issuer’s obligations under the Notes and this Indenture or (y) the amount, if any, which would not have (1) rendered the Guarantor
“insolvent” (as such term is defined in the Federal Bankruptcy Code and in the Debtor and Creditor Law of the State of New York) or (2) left it with unreasonably small capital at the time its guarantee with respect to the Notes was
entered into, after giving effect to the incurrence of existing Indebtedness immediately before such time; provided, however, it shall be a presumption in any lawsuit or proceeding in which a Guarantor is a party that the amount guaranteed
pursuant to the guarantee with respect to the Notes is the amount described in clause (x) above unless any creditor, or representative of creditors of the Guarantor, or debtor in possession or trustee in bankruptcy of the Guarantor, otherwise
proves in a lawsuit that the aggregate liability of the Guarantor is limited to the amount described in clause (y) above. 
 (b) In
making any determination as to the solvency or sufficiency of capital of a Guarantor in accordance with the proviso of 10.02(a), the right of each Guarantor to contribution from other Guarantors and any other rights such Guarantor may have,
contractual or otherwise, shall be taken into account. 

  
 70 

 Section 10.03 Execution and Delivery of Subsidiary Guarantee. 

To evidence its Subsidiary Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee
in substantially the form included in Exhibit B attached hereto shall be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Guarantor by
its President or one of its Vice Presidents. 
 Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01
shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee. 
 If an
Officer whose signature is on this Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall be valid nevertheless.

 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary
Guarantee set forth in this Indenture on behalf of the Guarantors. 
 The Issuer hereby agrees that it shall cause each Person that becomes
obligated to provide a Subsidiary Guarantee pursuant to Section 4.16 to execute a supplemental indenture in form and substance reasonably satisfactory to the Trustee, pursuant to which such Person provides the Guarantee set forth in this
Article 10 and otherwise assumes the obligations and accepts the rights of a Guarantor under this Indenture, in each case with the same effect and to the same extent as if such Person had been named herein as a Guarantor. The Issuer also hereby
agrees to cause each such new Guarantor to evidence its Guarantee by endorsing a notation of such Subsidiary Guarantee on each Note as provided in this Section 10.03. 

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms. 

Except as otherwise provided in Section 10.05, no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is
the surviving Person) another Person whether or not affiliated with such Guarantor unless: 
 (a) subject to Section 10.05, the Person
formed by or surviving any such consolidation or merger (if other than a Guarantor or the Issuer) unconditionally assumes all the obligations of such Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to
the Trustee, under this Indenture and any Subsidiary Guarantee on the terms set forth herein; and 
 (b) the Guarantor complies with the
requirements of Article 5 hereof (to the extent applicable). 
 In case of any such consolidation, merger, sale or conveyance and upon
the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and punctual performance of all of the
covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person
thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee. All the Subsidiary Guarantees
so issued shall in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had
been issued at the date of the execution hereof. 
 Except as set forth in Articles 4 and 5, and notwithstanding clauses (a) and
(b) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Issuer 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 Issuer or another Guarantor. 

  
 71 

 Section 10.05 Releases Following Merger, Consolidation or Sale of Assets, Etc. 

In the event of a sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or
otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) a Subsidiary of the Issuer, then such Guarantor (in the event of
a sale or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the
assets of such Guarantor) shall be released and relieved of any obligations under its Subsidiary Guarantee; provided that the net proceeds of such sale or other disposition shall be applied in accordance with the applicable provisions of this
Indenture, including without limitation Section 4.11. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary in accordance with the provisions of Section 4.15, such Subsidiary shall be released and relieved of any
obligations under its Subsidiary Guarantee. Upon delivery by the Issuer to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Issuer in accordance with the
provisions of this Indenture, including without limitation Section 4.11, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. 

Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and
interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

Issuer on its request or (if then held by the Issuer) shall be discharged from such trust; and the Holder shall thereafter, as an unsecured creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such cash and securities, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the

 Except as set forth in this
Section 2.1(b), beneficial interests in a Temporary Regulation S Global Note will not be exchangeable for interests in a Rule 144A Global Note, a permanent global note (the “Permanent
Regulation S Global Note” and, together with the Temporary Regulation S Global Note, the “Regulation S Global Note”) or any other Note prior to the expiration of the period
through and including the 40th day after the later of the commencement of the offering of the Initial Note or Additional Note represented by such Temporary Regulation S Global Note and the closing of such offering (such period, the
“Restricted Period”) and then, after the expiration of the Restricted Period, may be exchanged for interests in a Rule 144A Global Note or the Permanent Regulation S Global Note only upon certification in form reasonably
satisfactory to the Issuer and the Trustee that beneficial ownership interests in such Temporary Regulation S Global Note are owned either by non-U.S. persons or U.S. persons who purchased such interests in a
transaction that did not require registration under the Securities Act. 
 Prior to the expiration of the Restricted Period, beneficial
interests in a Temporary Regulation S Global Note may be exchanged for beneficial interests in the Rule 144A Global Note only if (i) such exchange occurs in connection with a transfer of the Notes pursuant to Rule 144A, (ii) the transferor
first delivers to the Trustee a written certificate to the effect that the beneficial interest in the Temporary Regulation S Global Note is being transferred to a Person who the transferor reasonably believes to be a QIB and is purchasing for its
own account or the account of a QIB, in each case in a transaction meeting the requirements of Rule 144A, and (iii) the transfer is in accordance with all applicable securities laws of the states of the United States and other jurisdictions.
After the expiration of the Restricted Period, such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Note representing Regulation S Global Notes. 

Beneficial interests in a Rule 144A Global Note that is a Transfer Restricted Note may be transferred to a Person who takes delivery in the
form of an interest in the Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in
accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available). 
 The aggregate principal amount of the Global Notes may from
time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as provided herein and in this Indenture. 

(c) Definitive Notes. Except as provided in Section 2.3 or 2.4, owners of beneficial interests in

 App. - 2 

 (a) Transfer and Exchange of Global Notes. The transfer and exchange of Global Notes or
beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a
beneficial interest in a Global Note shall deliver to the Registrar a written order given in accordance with the Depositary’s procedures containing information regarding the participant account of the Depositary to be credited with a beneficial
interest in the Global Note. The Registrar shall, in accordance with such instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account
of the Person making the transfer the beneficial interest in the Global Note being transferred. 
 (i) Notwithstanding any
other provisions of this Appendix, a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary
or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 (ii) In the event that a
Restricted Global Note is exchanged for Definitive Notes pursuant to Section 2.4, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this
Section 2.3 (including the certification requirements set forth on the reverse of the Transfer Restricted Notes intended to ensure that such transfers comply with Rule 144A or Regulation S or another applicable
exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer. 
 (b)
Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Registrar with a request (x) to register the transfer of such Definitive Notes or (y) to exchange such Definitive Notes for an equal principal
amount of Definitive Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Definitive Notes
surrendered for transfer or exchange: 
 (i) shall be duly endorsed or accompanied by a written instrument of transfer in
form reasonably satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 

(ii) if such Definitive Notes are required to bear a Restricted Notes legend, they are being transferred or exchanged pursuant
to an effective registration statement under the Securities Act, pursuant to Section 2.3(c) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents,
as applicable: 
 (A) if such Definitive Notes are being delivered to the Registrar by a Holder for registration in the name
of such Holder, without transfer, a certification from such Holder to that effect; or 
 (B) if such Definitive Notes are
being transferred to the Issuer or any Subsidiary of the Issuer, a certification to that effect; or 
 (C) if such
Definitive Notes are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of
the Securities Act: (I) a certification to that effect and (II) if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth
in Section 2.3(d)(i). 
 (c) Restrictions on Transfer of a Definitive Note for a Beneficial Interest in a
Global Note. A Definitive Note may not be exchanged for a beneficial interest in a Rule 144A Global Note or a Permanent Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a
Definitive Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 

  
 App. - 3 

 (i) certification that such Definitive Note is either (A) being transferred
to a QIB in accordance with Rule 144A, or (B) being transferred after expiration of the Restricted Period by a Person who initially purchased such Note in reliance on Regulation S to a buyer who elects to hold its interest in such Note in
the form of a beneficial interest in the Permanent Regulation S Global Note; and 
 (ii) written instructions directing
the Trustee to make, or directing the Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Note (in the case of a transfer pursuant to clause (c)(i)(A)) or Permanent Regulation S Global Note (in
the case of a transfer pursuant to clause (c)(i)(B)) to reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, such instructions to
contain information regarding the Depositary account to be credited with such increase, 
 then the Trustee shall cancel such Definitive Note and cause, or
direct the Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Custodian, the aggregate principal amount of Notes represented by the Rule 144A Global Note or Permanent Regulation S

 (ii) The Issuer, acting in its discretion, may
remove the Restricted Notes legend set forth in clause (d)(i) above from any Transfer Restricted Note at any time on or after the Resale Restriction Termination Date applicable to such Transfer Restricted Note. Without limiting the generality
of the preceding sentence, the Issuer may effect such removal by issuing and delivering, in exchange for such Transfer Restricted Note, an Unrestricted Note without such legend, registered to the same Holder and in an equal principal amount, and
upon receipt by the Trustee of a Company Order stating that the Resale Restriction Termination Date applicable to such Transfer Restricted Note has occurred and requesting the authentication and delivery of an Unrestricted Note in exchange therefor
given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date), the Trustee shall authenticate and deliver such Unrestricted Note to the
Depositary or pursuant to such Depositary’s instructions or hold such Note as Custodian and shall request the Depositary to, or, if the Trustee is custodian of such Transfer Restricted Note, shall itself, surrender such Transfer Restricted Note
in exchange for such Unrestricted Note without such legend and thereupon cancel such Transfer Restricted Note so surrendered, all as directed in such order. 

For purposes of this Section 2.3(d)(ii), all provisions relating to the removal of the legend set forth in clause (d)(i) above
shall relate, if the Resale Restriction Termination Date has occurred only with respect to a portion of the Notes evidenced by a Transfer Restricted Note, to such portion of the Notes so evidenced as to which the Resale Restriction Termination Date
has occurred. 
 Each holder of any Notes evidenced by any Restricted Global Note, by its acceptance thereof, (A) authorizes and consents to,
(B) appoints the Issuer as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such holder’s behalf, as the Depositary or the Trustee may
require to effect, and (C) upon the request of the Issuer, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depositary or the Trustee may require, or as shall otherwise be
necessary to effect, the removal of the legend set forth in Section 2.3(d)(i) (including by means of the exchange of all or the portion of such Restricted Global Note evidencing such Note for a certificate evidencing such
Note that does not bear such legend) at any time after the Resale Restriction Termination Date. 

  
 App. - 5 

 (iii) Upon any sale or transfer of a Transfer Restricted Note pursuant to
Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Note for a Note that does not bear the legend set forth in clause (d)(i) above and rescind any restriction on the
transfer of such Transfer Restricted Note, if the transferor thereof certifies in writing to the Registrar that, and if the Issuer or the Trustee so request, delivers an opinion of counsel to the effect that, such sale or transfer was made in
reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Note).

effective registration statement under the Securities Act, in each case, in accordance with any applicable securities laws of any state of the United States. 

(f) Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for
Definitive Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Issuer for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for Definitive Notes, redeemed, purchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Custodian for
such Global Note) with respect to such Global Note, by the Trustee or the Custodian, to reflect such reduction. 
 (g) No Obligation of
the Trustee. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in
any Note (including any transfers between or among Depositary participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to
do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

2.4 Definitive Notes. 

(a) A Global Note deposited with the Depositary or with the Trustee as custodian for the Depositary pursuant to
Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only in
the circumstances described in Section 2.08 of this Indenture and only if such transfer complies with Section 2.3 hereof.

surrendered by the Depositary or the Custodian located at its Corporate Trust Office to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of
such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.4 shall be executed, authenticated and delivered
only in denominations equal to $2,000 or an integral multiple of $1,000 in excess thereof, and registered in such names as the Depositary shall direct. Any Definitive Note delivered in exchange for an interest in a Global Note shall, except as
otherwise provided by Section 2.3, bear the Restricted Notes legend and Definitive Notes legend. 
 (c) In no
event shall beneficial interests in the Temporary Regulation S Global Note be transferred or exchanged for Definitive Notes prior to (x) the expiration of the Restricted Period and (y) the receipt by the Registrar of any certificates
required pursuant to Rule 903(b)(3)(ii)(B) of Regulation S under the Securities Act.

“Company”)), promises to pay interest on the principal amount of this Note at 5.375% per annum until maturity. The Issuer shall pay interest semi-annually on June 1 and December 1 of each year, commencing
December 1, 2018, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest shall accrue from the most recent date to which interest has been paid on the

from time to time at a rate that is 1.0% per annum in excess of the interest rate then in effect under the Indenture and this Note; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace periods), from time to time at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. 
 2. Method of Payment. The Issuer shall pay interest on the Notes (except
defaulted interest) to the Persons in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such Notes are cancelled
after such record date and on or before such Interest Payment Date, except as provided in Section 2.14 of the Indenture with respect to defaulted interest. The Notes shall be payable as to principal, premium, if any, and interest at the office
or agency of the Issuer maintained for such purpose, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the Note Register; provided, however, that payment by
wire transfer of immediately available funds shall be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer
or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, shall

the relevant record date to receive interest due on an Interest Payment Date falling prior to the Redemption Date), with an amount equal to or less than the net cash proceeds from one or more Equity Offerings to the extent such net cash proceeds are
received by or contributed to the Issuer; provided, however, that: 
 (i) at least 50% of the original aggregate principal
amount of the Initial Notes remains outstanding immediately after the occurrence of each such redemption (with any Notes held by the Issuer or its Restricted Subsidiaries being deemed to be not outstanding for the purposes of such calculation); and

 A-6 

 
transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Note or portion of a Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period

the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. 

14. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder, member,
manager or partner of the Issuer or any Guarantor, as such, shall have any liability for any Obligations of the Issuer or of the Guarantors under this Note, the Indenture, any supplemental indenture, the Subsidiary Guarantees, if any, or for any
claim based on, in respect of, or by reason of, such Obligations or their creation. Each Holder by accepting a Note waives and releases all such liability.

Issuer has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to 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. 
 18.
Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS NOTE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPALS OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER
