 Exhibit A-4 

 [Form of Reverse Side of Initial Note] 

6.500% Senior Notes due 2026 (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 November 5, 2015 until maturity at a rate per annum equal 6.500% . 
 The Company promises to pay interest semi-annually in arrears
on January 15 and July 15 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 January 15, 2016. 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 January 1 or July 1 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 Global Notes and all other 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. 
 (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 Twentieth Supplemental Indenture dated as of 

  
 Exhibit A-5 

 
November 5, 2015 (the “Twentieth Supplemental Indenture”; the Base Indenture, as supplemented by the Eleventh Supplemental Indenture, dated as of May 1, 2013 by and
among the Company, the guarantors party thereto and the Trustee, the Sixteenth Supplemental Indenture, dated as of August 11, 2014 by and among the Company, the guarantors party thereto and the Trustee, and the Nineteenth Supplemental
Indenture, dated as of September 28, 2015, by and among the Company, the guarantors party thereto and the Trustee, and as amended and supplemented in respect of the Notes by the Twentieth 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 January 15, 2021, 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 January 15 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	 
	 2021
	  	 	103.250	% 
	 2022
	  	 	102.167	% 
	 2023
	  	 	101.083	% 
	 2024 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 January 15, 2021, 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. 
  

  
 Exhibit A-6 

 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time
prior to January 15, 2019, 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 106.500% 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 January 15, 2021 (such
redemption price being set forth in the table appearing above under Section 5(a) hereof, plus (ii) all required interest payments due on the Note through January 15, 2021 (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 January 15, 2021; provided, however, that if the period from the
redemption date to January 15, 2021 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.

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.

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.

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.

 (16) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

(17) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.
