Section 4.17 of the Base Indenture, each such Note Guarantee to be governed by Article X of the Base Indenture (including without limitation the provisions for release of such Note Guarantee in respect of the Notes of this Series pursuant to
Section 10.04 of the Base Indenture).

The terms and provisions contained in the Notes of this Series will constitute, and are hereby expressly made, a part of this Third
Supplemental Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Third Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision

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 amount of any increase or decrease in the aggregate principal amount of outstanding Notes of
this Series represented thereby will be made by the Trustee or the Notes Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof.

the Notes of this Series in all respects, except for the issue date, the issue price, the initial Interest Payment Date and rights under a related registration rights agreement, if any. Any such Additional Notes shall be authenticated by the Trustee
upon receipt of a Company Order to that effect, and when so authenticated, will constitute “Notes” for all purposes of the Indenture and will (together with all other Notes of this Series issued under the Indenture) constitute a single
Series of Notes under the Indenture; provided that if such Additional Notes are not fungible with the Notes of this Series for U.S. federal income tax purposes, as applicable, as determined by the Company, such Additional Notes may have a
separate CUSIP number. 
 (a) The Notes of this Series issued on the Issue Date will be issued at an issue price of 100% of the
principal amount thereof. 
 (b) The principal amount of the Notes of this Series is due and payable in full on April 28,

Guarantors in accordance with the terms of the Indenture. 
 (i) The Company initially appoints the Trustee as Registrar and
Paying Agent with respect to the Notes of this Series until such time as the Trustee has resigned or a successor has been appointed. 
 (j) The Notes of this Series will initially be evidenced by one or more Definitive Notes issued in the name of DT. 
 (k) The Company shall pay principal of, premium, if any, and interest on the Notes of this Series in money of the United States of America that at the time of payment is legal tender for payment of public

the Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes of this Series of other denominations, the Registrar will register the transfer or make the exchange as requested if its
requirements for such transactions are met. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Notes of this Series at the Registrar’s request. A Holder of Notes of this Series may
transfer or exchange Notes of this Series only in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder of Notes of this Series, among other things, to furnish appropriate endorsements or
transfer documents. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith.

acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the holder of such Global Note (or its agent) or (b) any holder of
a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry.

 Exhibit A-4

 [Form of Reverse Side of Initial Note] 

Senior Reset Notes due 2021 (the “Notes”) 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Interest (computed on the basis of a 360-day year comprised of twelve 30-day months) shall accrue on the principal amount of this Note from and including April 28, 2013 to, but
not including, October 28, 2015 (the “Reset Date”) at 5.747% per annum, and (ii) from and including the Reset Date until maturity at a rate per annum equal to the Reset Rate, as determined by the Calculation Agent
according to the Pricing Mechanism set forth in Article IV of the Third Supplemental Indenture. 
 The Company promises to pay
interest semi-annually in arrears on April 28 and October 28 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 28,
2013. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If an Interest Payment Date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next
succeeding Business Day as if made on the date the payment was due, and no interest shall accrue for the intervening period. 

(2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered
Holders of Notes at the close of business on the April 15 or October 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.14 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New
York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the books and records of the Registrar; provided that payment by wire transfer of immediately available
funds will be required with respect to principal of and interest and premium, if any, on, all Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such money of the
United States of America as at the time of payment is legal tender for payment of public and private debts. The Holder of a Definitive Note is not required to surrender such Definitive Note to the Trustee in order to receive payment of principal at
maturity. Such Definitive Note, after payment has been made, shall be cancelled without the requirement of presentation. 
 (3)
PAYING AGENT AND REGISTRAR. Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The
Company or any of its Subsidiaries may act in any such capacity. 

  
 Exhibit A-5

 (4) INDENTURE. The Company issued the Notes pursuant to an Indenture dated as of
April 28, 2013 (the “Base Indenture”) among the Company, the Guarantors and the Trustee, as amended and supplemented with respect to the Notes by the Third Supplemental Indenture dated as of April 28, 2013 (the
“Third Supplemental Indenture”; the Base Indenture as amended and supplemented with respect to the Notes by the Third Supplemental Indenture, the “Indenture”). The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and, to the extent so included in the Indenture, to the TIA for a statement of such terms. To
the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured, unsubordinated obligations of the Company. The Indenture does not
limit the aggregate principal amount of Notes that may be issued thereunder. 
 (5) OPTIONAL REDEMPTION. 

(a) On or after April 28, 2018, the Company may redeem all or a part of the Notes upon not less than 10 nor more than 60 days’
notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of the Depositary to process such redemption on the date specified in such notice), at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but not including, the applicable redemption date, if redeemed during the twelve month period beginning on April 28 of the
years indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant Interest Payment Date for periods prior to such redemption date: 

 

					
	 Year
	  	Percentage	 
	 2018
	  	 	100.000% + ( 1/2 × Reset Rate	) 
	 2019
	  	 	100.000% + ( 1/4 × Reset Rate	) 
	 2020 and thereafter
	  	 	100.000	% 

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the
Notes or portions thereof called for redemption on the applicable redemption date. 
 At any time prior to April 28, 2018,
the Company may also redeem all or a part of the Notes, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of
Depositary to process such redemption on the date specified in such notice), at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but not including, the
date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such date of redemption. 

(b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to April 28, 2016, the Company
may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of 105.747% 

  
 Exhibit A-6

 
of the principal amount, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more sales of Equity Interests (other than Disqualified
Stock) of the Company or contributions to the Company’s common equity capital made with the net cash proceeds of one or more sales of Equity Interests (other than Disqualified Stock) of Parent; provided that: 

(1) at least 65% of the aggregate principal amount of Notes issued under the Indenture (excluding Notes held by the
Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 
 (2)
the redemption occurs within 180 days of the date of the closing of such sale of Equity Interests by the Company or the date of contribution to the Company’s common equity capital made with net cash proceeds of one or more sales of Equity
Interests of Parent. 
 “Applicable Premium” means, as calculated by the Company and provided to the Trustee,
with respect to any Note on any redemption date, the greater of: 
 (1) 1.0% of the principal amount of the Note;
or 
 (2) the excess of: 
 (a) the present value at such redemption date of (i) the redemption price of the Note at April 28, 2018 (such redemption price being set forth in the table appearing above under
Section 5(a) hereof (provided that if the redemption date is prior to the Reset Date, for purposes of calculating the redemption price under this clause (i) the Reset Rate shall be deemed to be 5.747%)), plus (ii) all required
interest payments due on the Note (determined, for purposes of calculating such interest payments under this clause (ii), with respect to periods from and after the Reset Date if the redemption date is prior to the Reset Date, as if the Reset Rate
would equal 5.747%) through April 28, 2018 (excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over 

(b) the principal amount of the Note, if greater. 

“Treasury Rate” means, with respect to any redemption date, the yield to maturity of United States Treasury securities
with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is
no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to April 28, 2018; provided, however, that if the period from the redemption date to
April 28, 2018 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used. The Company will (1) calculate the Treasury Rate on the third
business day preceding the applicable redemption date and (2) prior to such redemption date file with the trustee an officer’s certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in
reasonable detail. 

  
 Exhibit A-7

 (6) MANDATORY REDEMPTION. 

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

(7) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a Change of Control Triggering Event, the Company will be required to make a Change of Control Offer to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple
of $1,000 in excess thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest on the Notes repurchased to, but not including, the date of
purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date for periods prior to such repurchase date pursuant to Section 4.15 of the Base Indenture. Within 30 days
following any Change of Control Triggering Event, the Company will send a notice to each Holder and the Trustee describing the transaction or transactions and identify the ratings decline that together constitute the Change of Control Triggering
Event, offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent and setting forth the procedures governing the
Change of Control Offer as required by the Indenture. 
 (b) If the Company or a Restricted Subsidiary of the Company
consummates any Asset Sales, within twenty days of each date on which the aggregate amount of Excess Proceeds exceeds $100.0 million, the Company shall apply the entire aggregate amount of unutilized Excess Proceeds (not only the amount in excess of
$100.0 million) to make an Asset Sale Offer pursuant to Section 4.10 of the Base Indenture to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth
in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes (including any Additional Notes) and purchase or redeem such other pari passu Indebtedness
that may be purchased or redeemed out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount of the Notes and such other pari passu Indebtedness that may be purchased or redeemed with Excess
Proceeds thereof plus accrued and unpaid interest thereon to, but not including, the date of consummation of the purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes (including any
Additional Notes) and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Restricted Subsidiary) may use those Excess Proceeds for any purpose not otherwise prohibited
by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in response to such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Company shall
select such other pari passu Indebtedness to be purchased or redeemed on a pro rata basis unless otherwise required by law or applicable stock exchange or depositary requirements. Holders of Notes that are the subject of an offer to
purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

may be sent or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in

 (9)
DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the

outstanding Notes including Additional Notes, if any, voting as a single class, and any existing Default or Event or Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the
Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class. Without the consent of any Holder, the Company, the Guarantors and the Trustee may amend and supplement
the Indenture as provided in the Base Indenture. 
 (12) DEFAULTS AND REMEDIES. If an Event of Default occurs (other than
an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a
Significant Subsidiary) and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes, in each case, by notice to the Company, may declare the principal of, premium, if any, and accrued but unpaid
interest on all the Notes to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the
Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. 

  
 Exhibit A-9

 (13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee.

stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

authenticating agent.

 In accordance with Section 2.01 of the Base Indenture, the Company hereby creates a Series of Notes issued pursuant to the Indenture. The Notes of this Series shall be known and designated as the
“Senior Reset Notes due 2022” of the Company. The Notes of this Series shall be entitled to the benefits of the Note Guarantee of each Guarantor signatory hereto, or that may hereafter execute a supplemental indenture in accordance with
Section 4.17 of the Base Indenture, each such Note Guarantee to be governed by Article X of the Base Indenture (including without limitation the provisions for release of such Note Guarantee in respect of the Notes of this Series pursuant to
Section 10.04 of the Base Indenture). 
  

	Section 2.02	Forms Generally. 

 (a)
General. The Notes of this Series and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes of this Series may have notations, legends or endorsements required by law, stock exchange
rule or usage. Each Note of this Series will be dated the date of its authentication. The Notes of this Series shall be in minimum denominations of $2,000 and integral multiples of $1,000. 

The terms and provisions contained in the Notes of this Series will constitute, and are hereby expressly made, a part of this Fourth
Supplemental Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Fourth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision

 -3-

 (b) Global Notes. Notes of this Series issued in global form will be substantially in
the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes of this Series issued in definitive form will be substantially in the form of
Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes of this Series as will be
specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes of this Series from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes of this Series 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 amount of any increase or decrease in the aggregate principal amount of outstanding Notes of
this Series represented thereby will be made by the Trustee or the Notes Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof. 

 

	Section 2.03	Title and Terms of Notes. 

 The aggregate
principal amount of Notes of this Series which shall be authenticated and delivered on the Issue Date under the Indenture shall be $1,250,000,000; provided, however, that subject to the Company’s compliance with Section 4.09
of the Base Indenture, the Company from time to time, without giving notice to or seeking the consent of the Holders of Notes of this Series, may issue additional notes (the “Additional Notes”) in any amount having the same terms as
the Notes of this Series in all respects, except for the issue date, the issue price, the initial Interest Payment Date and rights under a related registration rights agreement, if any. Any such Additional Notes shall be authenticated by the Trustee
upon receipt of a Company Order to that effect, and when so authenticated, will constitute “Notes” for all purposes of the Indenture and will (together with all other Notes of this Series issued under the Indenture) constitute a single
Series of Notes under the Indenture; provided that if such Additional Notes are not fungible with the Notes of this Series for U.S. federal income tax purposes, as applicable, as determined by the Company, such Additional Notes may have a
separate CUSIP number. 
 (a) The Notes of this Series issued on the Issue Date will be issued at an issue price of 100% of the
principal amount thereof. 
 (b) The principal amount of the Notes of this Series is due and payable in full on April 28,
2022 unless earlier redeemed. 
 (c) The Notes of this Series shall bear interest (computed on the basis of a 360-day year
comprised of twelve 30-day months) at the rate of (i) 5.845% per annum from and including the Issue Date to, but not including, the Reset Date, and (ii) from and including the Reset Date until maturity at a rate per annum equal to the
Reset Rate, as determined by the Calculation Agent according to the Pricing Mechanism set forth in Article IV of this Fourth Supplemental Indenture, or, in each case, until early redemption; and interest will be payable semi-annually in arrears on
April 28 and October 28 of each year (each, an “Interest Payment Date”), commencing October 28, 2013, to the Persons in whose name such Notes of this Series were registered at the close of business on the preceding
April 15 or October 15, respectively. 

  
 -4-

 (d) Principal of and interest on the Notes of this Series shall be payable as set forth in
Exhibit A. 
 (e) Other than as provided in Article III of this Fourth Supplemental Indenture, the Notes of this Series shall
not be redeemable. 
 (f) The Notes of this Series shall not be entitled to the benefit of any mandatory redemption or sinking
fund. 
 (g) The Notes of this Series shall not be convertible into any other securities. 

(h) The Notes of this Series will be unsubordinated debt securities and will be entitled to unsubordinated Note Guarantees of the
Guarantors in accordance with the terms of the Indenture. 
 (i) The Company initially appoints the Trustee as Registrar and
Paying Agent with respect to the Notes of this Series until such time as the Trustee has resigned or a successor has been appointed. 
 (j) The Notes of this Series will initially be evidenced by one or more Definitive Notes issued in the name of DT. 
 (k) The Company shall pay principal of, premium, if any, and interest on the Notes of this Series in money of the United States of America that at the time of payment is legal tender for payment of public
and private debts. 
 (l) The terms and provisions of Appendix A of the Base Indenture shall apply to the Notes of this Series.

  

	Section 2.04	Transfer and Exchange. 

The Notes of this Series shall be issued in registered form and shall be transferable only upon the surrender of a Note of this Series for
registration of transfer and in compliance with Appendix A of the Base Indenture. 
 When Notes of this Series are presented to
the Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes of this Series of other denominations, the Registrar will register the transfer or make the exchange as requested if its
requirements for such transactions are met. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Notes of this Series at the Registrar’s request. A Holder of Notes of this Series may
transfer or exchange Notes of this Series only in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder of Notes of this Series, among other things, to furnish appropriate endorsements or
transfer documents. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith. 

  
 -5-

 Exhibit A-4

 [Form of Reverse Side of Initial Note] 

Senior Reset Notes due 2022 (the “Notes”) 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Interest (computed on the basis of a 360-day year comprised of twelve 30-day months) shall accrue on the principal amount of this Note from and including April 28, 2013 to, but
not including, October 28, 2015 (the “Reset Date”) at 5.845% per annum, and (ii) from and including the Reset Date until maturity at a rate per annum equal to the Reset Rate, as determined by the Calculation Agent
according to the Pricing Mechanism set forth in Article IV of the Fourth Supplemental Indenture. 
 The Company promises to pay
interest semi-annually in arrears on April 28 and October 28 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 28,
2013. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If an Interest Payment Date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next
succeeding Business Day as if made on the date the payment was due, and no interest shall accrue for the intervening period. 

(2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered
Holders of Notes at the close of business on the April 15 or October 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.14 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New
York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the books and records of the Registrar; provided that payment by wire transfer of immediately available
funds will be required with respect to principal of and interest and premium, if any, on, all Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such money of the
United States of America as at the time of payment is legal tender for payment of public and private debts. The Holder of a Definitive Note is not required to surrender such Definitive Note to the Trustee in order to receive payment of principal at
maturity. Such Definitive Note, after payment has been made, shall be cancelled without the requirement of presentation. 
 (3)
PAYING AGENT AND REGISTRAR. Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The
Company or any of its Subsidiaries may act in any such capacity. 

  
 Exhibit A-5

 (4) INDENTURE. The Company issued the Notes pursuant to an Indenture dated as of
April 28, 2013 (the “Base Indenture”) among the Company, the Guarantors and the Trustee, as amended and supplemented with respect to the Notes by the Fourth Supplemental Indenture dated as of April 28, 2013 (the
“Fourth Supplemental Indenture”; the Base Indenture as amended and supplemented with respect to the Notes by the Fourth Supplemental Indenture, the “Indenture”). The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and, to the extent so included in the Indenture, to the TIA for a statement of such terms. To
the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured, unsubordinated obligations of the Company. The Indenture does not
limit the aggregate principal amount of Notes that may be issued thereunder. 
 (5) OPTIONAL REDEMPTION. 

(a) On or after April 28, 2018, the Company may redeem all or a part of the Notes upon not less than 10 nor more than 60 days’
notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of the Depositary to process such redemption on the date specified in such notice), at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but not including, the applicable redemption date, if redeemed during the twelve month period beginning on April 28 of the
years indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant Interest Payment Date for periods prior to such redemption date: 

 

					
	 Year
	 	Percentage	 
	 2018
	 	 	100.000% + ( 1/2 × Reset Rate)	  
	 2019
	 	 	100.000% + ( 1/4 × Reset Rate)	  
	 2020 and thereafter
	 	 	100.000	% 

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the
Notes or portions thereof called for redemption on the applicable redemption date. 
 At any time prior to April 28, 2018,
the Company may also redeem all or a part of the Notes, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of
Depositary to process such redemption on the date specified in such notice), at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but not including, the
date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such date of redemption. 

(b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to April 28, 2016, the Company
may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of 105.845% 

  
 Exhibit A-6

 
of the principal amount, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more sales of Equity Interests (other than Disqualified
Stock) of the Company or contributions to the Company’s common equity capital made with the net cash proceeds of one or more sales of Equity Interests (other than Disqualified Stock) of Parent; provided that: 

(1) at least 65% of the aggregate principal amount of Notes issued under the Indenture (excluding Notes held by the
Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 
 (2)
the redemption occurs within 180 days of the date of the closing of such sale of Equity Interests by the Company or the date of contribution to the Company’s common equity capital made with net cash proceeds of one or more sales of Equity
Interests of Parent. 
 “Applicable Premium” means, as calculated by the Company and provided to the Trustee,
with respect to any Note on any redemption date, the greater of: 
 (1) 1.0% of the principal amount of the Note;
or 
 (2) the excess of: 
 (a) the present value at such redemption date of (i) the redemption price of the Note at April 28, 2018 (such redemption price being set forth in the table appearing above under
Section 5(a) hereof (provided that if the redemption date is prior to the Reset Date, for purposes of calculating the redemption price under this clause (i) the Reset Rate shall be deemed to be 5.845%)), plus (ii) all required
interest payments due on the Note (determined, for purposes of calculating such interest payments under this clause (ii), with respect to periods from and after the Reset Date if the redemption date is prior to the Reset Date, as if the Reset Rate
would equal 5.845%) through April 28, 2018 (excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over 

(b) the principal amount of the Note, if greater. 

“Treasury Rate” means, with respect to any redemption date, the yield to maturity of United States Treasury securities
with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is
no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to April 28, 2018; provided, however, that if the period from the redemption date to
April 28, 2018 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used. The Company will (1) calculate the Treasury Rate on the third
business day preceding the applicable redemption date and (2) prior to such redemption date file with the trustee an officer’s certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in
reasonable detail. 

  
 Exhibit A-7

 (6) MANDATORY REDEMPTION. 

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

(7) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a Change of Control Triggering Event, the Company will be required to make a Change of Control Offer to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple
of $1,000 in excess thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest on the Notes repurchased to, but not including, the date of
purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date for periods prior to such repurchase date pursuant to Section 4.15 of the Base Indenture. Within 30 days
following any Change of Control Triggering Event, the Company will send a notice to each Holder and the Trustee describing the transaction or transactions and identify the ratings decline that together constitute the Change of Control Triggering
Event, offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent and setting forth the procedures governing the
Change of Control Offer as required by the Indenture. 
 (b) If the Company or a Restricted Subsidiary of the Company
consummates any Asset Sales, within twenty days of each date on which the aggregate amount of Excess Proceeds exceeds $100.0 million, the Company shall apply the entire aggregate amount of unutilized Excess Proceeds (not only the amount in excess of
$100.0 million) to make an Asset Sale Offer pursuant to Section 4.10 of the Base Indenture to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth
in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes (including any Additional Notes) and purchase or redeem such other pari passu Indebtedness
that may be purchased or redeemed out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount of the Notes and such other pari passu Indebtedness that may be purchased or redeemed with Excess
Proceeds thereof plus accrued and unpaid interest thereon to, but not including, the date of consummation of the purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes (including any
Additional Notes) and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Restricted Subsidiary) may use those Excess Proceeds for any purpose not otherwise prohibited
by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in response to such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Company shall
select such other pari passu Indebtedness to be purchased or redeemed on a pro rata basis unless otherwise required by law or applicable stock exchange or depositary requirements. Holders of Notes that are the subject of an offer to
purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

  
 Exhibit A-8

 (8) NOTICE OF REDEMPTION. Notice of redemption will be sent at least 30 days (or, if
any Global Notes are outstanding, such shorter period as may be permitted by the eligibility rules of the Depositary) but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed, except that redemption notices
may be sent or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in
part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. 
 (9)
DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the
Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company need not exchange or register the transfer or exchange 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 Company need not exchange or
register the transfer of any Notes (i) for a period beginning at the opening of business 15 days immediately preceding the sending of notice of redemption of Notes selected for redemption and ending at the close of business on the day such
notice is sent or (ii) during the period between a record date and the corresponding Interest Payment Date. 
 (10)
PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 
 (11)
AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then
outstanding Notes including Additional Notes, if any, voting as a single class, and any existing Default or Event or Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the
Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class. Without the consent of any Holder, the Company, the Guarantors and the Trustee may amend and supplement
the Indenture as provided in the Base Indenture. 
 (12) DEFAULTS AND REMEDIES. If an Event of Default occurs (other than
an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a
Significant Subsidiary) and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes, in each case, by notice to the Company, may declare the principal of, premium, if any, and accrued but unpaid
interest on all the Notes to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the
Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. 

  
 Exhibit A-9

 (13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. 

(14) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, member, manager, partner, employee, incorporator or
stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 

(15) AUTHENTICATION. This Note will not be valid until authenticated by the manual or facsimile signature of the Trustee or an
authenticating agent.
