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
