Transaction Closing Date does not occur on or prior to September 30, 2017 or if the Merger Agreement is terminated at any time on or prior to September 30, 2017 (each of such events being a “Special Mandatory Redemption
Trigger”), then the Company will redeem in whole and not in part the aggregate principal amount of the Notes outstanding on the Special Mandatory Redemption Date at the Special Mandatory Redemption Price, plus accrued and unpaid interest
from and including the date of initial issuance, or the most recent date to which interest has been paid, whichever is later, to, but excluding, the Special Mandatory Redemption Date (the “Special Mandatory Redemption”) (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date). 
 (b) The Company
will cause a notice of Special Mandatory Redemption to be delivered to the Trustee and mailed, or delivered electronically in accordance with DTC’s customary procedures if held by DTC, to the Holders of the Notes, at their registered addresses,

 12 








 
Redemption Trigger, which shall provide for the redemption of the notes on or prior to the third business day (the “Special Mandatory Redemption Date”) following the date of such

interest and all rights under such Notes shall terminate. 
 (c) Upon the occurrence of the Transaction Closing Date, the provisions
described in this Section 1.05 will cease to apply.

and the property encumbered by any such Lien is the same as or substantially similar in nature to the property encumbered by the Lien being extended, renewed or replaced. 

Notwithstanding the foregoing, the Company or any of its Subsidiaries may create, incur, assume or suffer to exist Indebtedness secured by
Liens not otherwise permitted by this Section 1.06(a) if the Company first makes effective provisions whereby each series of Notes (together with any other Indebtedness of the Company then existing or thereafter created ranking equally with such

 (iii) the Company would be entitled to incur Indebtedness secured by a mortgage on the property to be leased in an amount

and Section 1.06(b), the Company or any of its Restricted Subsidiaries may create, incur, assume or suffer to exist any Lien or enter into any sale and lease-back transaction not otherwise permitted pursuant to Section 1.06(a) or Section 1.06(b);
provided that, at the time of such event, and after giving effect to that event, the aggregate amount of all Indebtedness secured by Liens permitted by this Section 1.06(c) (excluding the Liens permitted pursuant to Section 1.06(a)) and the
aggregate amount of all Attributable Debt in respect of sale and lease-back transactions permitted by this Section 1.06(c) (excluding sale and lease-back transactions permitted under Section 1.06(b)) measured, in each case, at the time any such Lien

 16 








 (d) Purchase of Notes upon a Change of Control Triggering Event. (i) If a Change of
Control Triggering Event occurs with respect to a particular series of Notes, unless the Company has exercised its option to redeem such Notes as described in Section 1.04 or Section 1.05 hereof, the Company will make an offer (a
“Change of Control Offer”) to each Holder of such Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price, payable in cash, equal to
101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, on the Notes repurchased to, but excluding, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change
of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be sent to Holders of the Notes,
with a copy to the Trustee, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date will be no earlier than 30 days
and no later than 90 days from the date such notice is delivered (the “Change of Control Payment Date”). The notice will, if delivered prior to the date of consummation of the Change of Control, state that the offer to purchase is
conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date and shall state the following: 

(A) that the Change of Control Offer is being made pursuant to this Section 1.06(d) and that all Notes tendered will be
accepted for payment; 
 (B) the purchase price and the purchase date, which shall be no earlier than 30 days and no later
than 90 days from the date such notice is mailed; 
 (C) that any Note not tendered will continue to accrue interest; 

(D) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant
to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (E) that Holders
electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry
transfer, to the paying agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 

  
 17 








 (F) that Holders will be entitled to withdraw their election if the paying agent
receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered
for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (G) that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral
multiple of $1,000 in excess thereof. 
 The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a
Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 1.06(d), the Company will comply with the applicable securities laws and regulations and will
not be deemed to have breached its obligations under this Section 1.06(d) by virtue of such compliance. 
 (ii) On the Change
of Control Payment Date, the Company will, to the extent lawful: 
 (A) accept for payment all Notes or portions of Notes
properly tendered pursuant to the Change of Control Offer; 
 (B) deposit with the paying agent an amount equal to the Change
of Control Payment in respect of all Notes or portions of Notes properly tendered; and 
 (C) deliver or cause to be
delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased. 

The paying agent will promptly deliver (but in any case not later than five days after the Change of Control Payment Date) to
each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and deliver (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any
unpurchased portion of the Notes surrendered, if any. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

  
 18 








 (iii) Notwithstanding anything to the contrary in this Section 1.06(d), the
Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if (a) a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements
set forth in this Section 1.06(d) and the third party repurchases all Notes properly tendered and not withdrawn under its offer, or (b) notice of redemption has been given pursuant to Section 1.04 or Section 1.05 hereof, unless and
until there is a default in payment of the applicable Redemption Price. 
 Section 1.07. Defaults and Remedies. (a) Events
of Default. This Section 1.07(a) shall replace Section 4.01 of the Base Indenture with respect to the Notes only. 
 Each of the
following is an “Event of Default” with respect to a particular series of Notes: 
 (i) default in the
payment of interest, including additional interest, if any, on such series of Notes when due, and such default has continued for a period of 90 days or more and the time for such payment is due has not been extended or deferred; 

(ii) default in the payment (at maturity, upon redemption or otherwise) of the principal of such series of Notes when due; 

(iii) failure by the Company for 90 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes of such series then Outstanding to perform or observe any of the other covenants or agreements in this Indenture applicable to such series (other than defaults specified in clauses (i) or (ii) above); 

(iv) any of the Company’s Indebtedness in the aggregate outstanding principal amount of $250 million or more either:

 (A) becomes due and payable prior to the due date for payment of such Indebtedness by reason of acceleration of such
Indebtedness following a default by the Company; or 
 (B) is not repaid at, and remains unpaid after, maturity as extended
by any applicable period of grace or any guarantee given by us in respect of Indebtedness of any other Person in the aggregate outstanding principal amount of $250 million or more is not honored when, and remains dishonored after, becoming due;

 (v) the Company pursuant to or within the meaning of any Bankruptcy Law (A) commences a voluntary case,
(B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a Custodian of it or for all or substantially all of its property or (D) makes a general assignment for the benefit
of its creditors; or 

  
 19 








 (vi) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that (A) is for relief against the Company in an involuntary case, (B) appoints a Custodian of the Company for all or substantially all of the Company’s properties, or (C) orders the liquidation of the Company,
and, in any of the above cases, the order or decree remains unstayed and in effect for 90 days. 
 (b) Acceleration of Maturity. In
the case of an Event of Default specified in clause (v) or (vi) of Section 1.07(a), all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes of a particular series may declare all the Notes of such series to be due and payable immediately by notice in writing to the Company (and to the
Trustee if written notice is given by such Holders). Upon any such declaration, the Notes of such series shall become due and payable immediately. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes of a particular series by written notice to the Trustee
may, on behalf of all of the Holders of such series, rescind an acceleration and its consequences with respect to such series of Notes, if the rescission would not conflict with any judgment or decree and if all existing Events of Default with
respect to such series of Notes (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived. 

Section 1.08. Book-Entry Provisions for Global Notes. (a) Each Global Note initially shall (i) be registered in the name of
the Depositary for such Global Note or the nominee of such Depositary, in each case for credit to the account of an Agent Member, and (ii) be delivered to the Trustee as custodian for such Depositary. None of the Company, any agent of the
Company or the Trustee shall 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. 
 (b) Members of, or participants in, the Depositary (“Agent Members”)
shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or its custodian, or under such Global Notes. The Depositary may be treated by the Company, any other obligor upon the Notes, the
Trustee and any agent of any of them as the absolute owner of the Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, any other obligor upon the Notes, the Trustee or any agent of any of
them from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a
beneficial owner of any Note. The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take
under this Indenture or the Notes. 

  
 20 








 (c) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but,
subject to the immediately succeeding sentence, not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may not be transferred or exchanged for physical Notes unless (i) the
Company has consented thereto in writing, or such transfer or exchange is made pursuant to the next sentence, and (ii) such transfer or exchange is in accordance with the applicable rules and procedures of the Depositary. Subject to the
limitation on issuance of physical Notes, physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the relevant Global Note, if (i) the Depositary notifies the Company at any time that it is
unwilling or unable to continue as Depositary for the Global Notes and a successor depositary is not appointed within 120 days; (ii) the Depositary ceases to be registered as a “Clearing Agency” under the Exchange Act and a successor
depositary is not appointed within 120 days; or (iii) the Company, at its option, notifies the Trustee that it elects to cause the issuance of physical Notes. 

(d) The transfer and exchange of a Global Note or beneficial interests therein shall be effected through the Depositary, in accordance with
this Indenture (including applicable restrictions on transfer set forth in Section 1.09) and the Applicable Procedures therefor of the Depositary. Any beneficial interest in one of the Global Notes that is transferred to a Person who takes
delivery in the form of an interest in a different Global Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer
restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. 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 Applicable Procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the relevant Global Note. Subject to Section 1.09, 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 such Global Note and to debit the account of the Person making the transfer
the beneficial interest in the Global Note being transferred. 
 (e) Any physical Note delivered in exchange for an interest in a Global Note
pursuant to Section 1.08(c) shall, unless such exchange is made on or after the Resale Restriction Termination Date applicable to such Note, bear the Notes Legends. 

(f) Notwithstanding the foregoing, through the Restricted Period, a beneficial interest in a Regulation S Global Note may be held only through
designated Agent Members holding on behalf of Euroclear or Clearstream unless delivery is made in accordance with the applicable provisions of Section 1.09. 

Section 1.09. Special Transfer Provisions. (a) Transfers to Non-U.S. Persons.
The following provisions shall apply with respect to the registration of any proposed transfer of a Note that is a Restricted Security to any Non-U.S. Person: The Registrar shall register such transfer if it
complies with all other applicable requirements of this Indenture and: 

  
 21 








 (i) (x) such transfer is after the relevant Resale Restriction Termination
Date with respect to such Note or (y) the proposed transferor has delivered to the Registrar and the Company and the Trustee an Opinion of Counsel, certifications and other information satisfactory to the Company, and 

(ii) if the proposed transferor is or is acting through an Agent Member holding a beneficial interest in a Global Note, upon
receipt by the Registrar and the Company and the Trustee of (x) the certificate, opinion, certifications and other information, if any, required by clause (a)(i) above and (y) written instructions given in accordance with the procedures of
the Registrar and the Applicable Procedures of the Depositary; 
 whereupon (i) the Registrar shall reflect on its books and records the date and a
decrease in the principal amount of the relevant Global Note in an amount equal to the principal amount of the beneficial interest in the relevant Global Note to be transferred, and (ii) if the proposed transferee is or is acting through an
Agent Member holding a beneficial interest in a relevant Regulation S Global Note, the Registrar shall reflect on its books and records the date and an increase in the principal amount of such Regulation S Global Note in an amount equal to the
principal amount of the beneficial interest being so transferred. 
 (b) Transfers to QIBs. The following provisions shall apply with
respect to the registration of any proposed transfer of a Note that is a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons): The Registrar shall register such transfer if it complies with
all other applicable requirements of this Indenture and, if such transfer is being made by a proposed transferor who has checked the box provided for on the form of such Note stating, or has otherwise certified to the Registrar and the Company and
the Trustee in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of such Note stating, or has otherwise certified to Registrar and the
Company and the Trustee in writing, that it is purchasing such Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is
aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is
aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A. 

(c) Other Transfers. The Registrar shall effect and register, upon receipt of a written request from the Company to do so, a transfer
not otherwise permitted by this Section 1.09, such registration to be done in accordance with the otherwise applicable provisions of this Section 1.09, upon the furnishing by the proposed transferor or transferee of a written Opinion of
Counsel (which opinion and counsel are satisfactory to the Company) to the effect that, and such other certifications or information as the Company may require to confirm that, the proposed transfer is being made pursuant to an exemption from, or in
a transaction not subject to, the registration requirements of the Securities Act. 

  
 22 








 (d) General. A Note that is a Restricted Security may not be transferred other than as
provided in this Section 1.09. A beneficial interest in a Global Note that is a Restricted Security may not be exchanged for a beneficial interest in another Global Note other than through a transfer in compliance with this Section 1.09.
By its acceptance of any Note bearing the Note Legends, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Note Legends and agrees that it will transfer such Note only as provided
in this Indenture. 
 Section 1.10. Payment of Additional Interest. (a) Under certain circumstances the Company may be
obligated to pay certain additional amounts of interest to the Holders of certain Notes. 
 (b) Prior to any Interest Payment Date on which
any such additional interest is payable, the Company shall give notice to the Trustee of the amount of any such additional interest due on such Interest Payment Date. The Trustee shall have no obligation to independently determine whether additional
interest is payable or to confirm the amount of additional interest that is in fact payable. 
 Section 1.11. Satisfaction and
Discharge of Indenture. This Section 1.11 shall replace Section 9.01(a) of the Base Indenture with respect to the Notes only.  

(a) either (i) all the Notes of such series that have been authenticated and delivered have been cancelled or delivered to the Trustee for
cancellation (other than any Notes of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 of the Base Indenture); or (ii) all the Notes of such series issued
that have not been cancelled or delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable at their final maturity within one year, or are to be called for redemption within one year,
under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Company’s name, and at the Company’s expense and the Company shall have irrevocably deposited or caused to be deposited
with the Trustee sufficient funds to pay and discharge the entire indebtedness on the Notes of such series to pay principal, interest, if any, and any premium, which for purposes of this provision shall be calculated without applying any
“present value discount” and using a Treasury Rate of no less than zero. 
 Section 1.12. Successors. Upon any
consolidation or merger, or any sale, transfer, lease, conveyance or other disposition of the assets of the Company substantially as an entirety in a transaction that is subject to, and that complies with the provisions of, Article 8 of the Base
Indenture, the successor Person formed by such consolidation or into or with which the Company is merged or to which such sale, lease, transfer, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after
the date of such consolidation, merger, sale, lease, transfer, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may
exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to
pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, this Section 1.12.

Indenture and the Notes with the written consent (including consents obtained in connection with a tender offer or exchange offer for Notes) of the Holders of a majority in principal amount of the then outstanding Notes, and compliance with any
provision of the Indenture and the Notes may be waived with the written consent (including consents obtained in connection with a tender offer or exchange offer for Notes) of the Holders of a majority in principal amount of the then outstanding
Notes. The Company and the Trustee may amend or supplement the Indenture and the Notes without notice to or consent of any Holder as provided in the Indenture, including, without limitation, to cure any ambiguity, defect or inconsistency or make any
change that would not adversely affect the legal rights under the Indenture of any Holder in any material respect. 
 13. Defaults and
Remedies. If an Event of Default with respect to the Notes occurs and is continuing (other than an Event of Default in Section 1.07(a)(v) or 1.07(a)(vi) of the First Supplemental Indenture), then in every such case the Trustee or the Holders of
not less than 25% in principal amount of the outstanding Notes may declare the principal amount of and accrued and unpaid interest, if any, on all the Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon such declaration such principal amount and accrued and unpaid interest, if any, shall become immediately due and payable. If an Event of Default specified in Sections 1.07(a)(v) or 1.07(a)(vi) of the First
Supplemental Indenture shall occur, the principal of and accrued and unpaid interest, if any, on all outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee
or any Holder of outstanding Notes. Subject to the terms of the Indenture, if an Event of Default under the Indenture shall occur and be continuing, the Trustee will be under no obligation to exercise any of the rights or powers vested in it by the
Indenture at the request or direction of any of the Holders unless such Holders shall have offered the Trustee security or indemnity satisfactory to it. Upon satisfaction of certain conditions set forth in the Indenture, the Holders of a majority in
principal amount of the outstanding Notes 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.

any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability.

occur and be continuing, the Trustee will be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request or direction of any of the Holders unless such Holders shall have offered the Trustee security or
indemnity satisfactory to it. Upon satisfaction of certain conditions set forth in the Indenture, the Holders of a majority in principal amount of the outstanding Notes 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. 

14. Trustee May Hold Securities. The Trustee, subject to certain limitations imposed by the Trust Indenture Act, in its individual or
any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, paying agent or Registrar.

any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability.
