 Section 1.05 Acts of Holders. A Holder entitled to take any action hereunder
with regard to any particular Note may do so with regard to all or any portion (in an authorized denomination) of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with
regard to all or any portion (in an authorized denomination) of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different portions of such principal amount pursuant to this Section shall have the same
effect as if given or taken by separate Holders of each such different portion. 
 ARTICLE II 

THE NOTES 

Section 2.01 Form and Dating. 
 (a) The Notes and the Trustee’s certificate of authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this
Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange or automated quotation system rule or regulation or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in
writing. Each Note shall be dated the date of its authentication. 
 (b) (1) All of the Unrestricted Notes shall be issued
initially in the form of a Global Note, which shall be deposited with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company (“DTC”, and such depositary, or any successor thereto, being
hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor thereto), for the accounts of participants in the Depositary, duly executed by the Company and authenticated by
the Trustee as hereinafter provided. The aggregate principal amount of a Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Notes Custodian as hereinafter provided, subject in each
case to compliance with the Applicable Procedures. 
 (2) All of the Restricted Notes shall be issued initially
in the form of Certificated Notes (the “Restricted Certificated Notes”), duly executed by the Company and authenticated by the Trustee as hereinafter provided, and shall bear the Private Placement Legend set forth in Exhibit D. 

(c) Each Global Note shall represent such of the outstanding Unrestricted Notes as shall be specified therein and each shall provide that
it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate,
to reflect issuances, replacements, exchanges, purchases, redemptions, 

  
 -28-









 
or transfers of such Notes, including exchanges of Restricted Certificated Notes for beneficial interests in a Global Note. Any adjustment of the aggregate principal amount of a Global Note to
reflect the amount of any increase or decrease in the aggregated principal amount of outstanding Notes represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and
shall be made on the records of the Trustee, the Notes Custodian and the Depositary. 
 (d) 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 under any Global Note, and the Depositary (including, for this purpose, its nominee) may be
treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any Note. 
 (e) The Company shall execute and the
Trustee shall, in accordance with this Section 2.01(e), authenticate and deliver initially one or more Global Notes representing Unrestricted Notes that (1) shall be registered in the name of the Depositary or its nominee, (2) shall
be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (3) shall bear a legend substantially to the following effect: 
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY
AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN. THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE THEREOF. THIS NOTE IS EXCHANGEABLE FOR NOTES REGISTERED IN THE NAME OF A PERSON OTHER THAN
THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR A NOTE IN CERTIFICATED FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE
DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE 

  
 -29-









 
DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.” 

(f) The Company shall execute and the Trustee shall, in accordance with this Section 2.01(f), authenticate and deliver initially
Certificated Notes representing Restricted Notes that (1) shall each be registered in the name of a Holder thereof in accordance with the Purchase Agreement, (2) shall be delivered by the Trustee to the respective Holder and (3) shall
bear the Private Placement Legend. 
 Section 2.02 Execution and Authentication. 

(a) The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is
*[$        ]. 
 (b) An Officer shall sign the Notes for the Company by manual or
facsimile signature. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Note that has been authenticated and delivered by the Trustee. 

(c) If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall
be valid nevertheless. 
 (d) A Note shall not be valid until an authorized signatory of the Trustee by manual signature signs
the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 (e) The Trustee shall authenticate and make available for delivery Notes for original issue upon receipt of a written order or orders of the Company signed by an Officer of the Company (a “Company
Order”). The Company Order shall specify the total amount of Notes to be authenticated, the amount of such Notes which are Unrestricted Notes and the amount of such Notes which are Restricted Notes, whether such Notes will be represented by a
Global Note or Certificated Notes and the date on which each original issue of Notes is to be authenticated. 
 (f) The Trustee
shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 

(g) The Notes shall be issuable only in registered form without coupons and only in denominations of $2,000 principal amount and any
integral multiple of $1,000 in excess thereof. 

  
 -30-









 Section 2.03 Registrar and Paying Agent. 

(a) The Company shall maintain one or more offices or agencies where Notes may be presented for registration of transfer or for exchange
(each, a “Registrar”) and one or more offices or agencies where Notes may be presented for payment (each, a “Paying Agent”). One of the Registrars (the “Primary Registrar”) shall keep a register of the Notes and of
their transfer and exchange. The Company may change any Paying Agent or Registrar without prior notice to any Holder of Notes, provided that the Company will deliver written notice of any such change in Paying Agent or Registrar to each
Holder of a Note within two Business Days after such change. 
 (b) The Company shall enter into an appropriate agency agreement
with any Agent not a party to this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the
Company may act as Paying Agent (except for the purposes of Section 4.01 and Article XII). 
 (c) The Company hereby
initially designates the Trustee as Paying Agent, Registrar and Notes Custodian. 
 Section 2.04 Paying Agent to Hold
Money in Trust. Prior to 12:00 p.m. (noon), New York City time, on each due date of the payment of principal of, or interest on, any Notes, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal or interest
so becoming due. Subject to Section 12.03, a Paying Agent shall hold in trust for the benefit of Holders of Notes or the Trustee all money held by the Paying Agent for the payment of principal of, or interest on, the Notes, and shall notify the
Trustee in writing of any failure by the Company (or any other obligor on the Notes) to make any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 12:00 p.m. (noon), New York City time, on each
due date of the principal of, or interest on, any Notes, segregate the money held by it as Paying Agent and hold it as a separate trust fund for the benefit of Holders of Notes. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee, and the Trustee may at any time during the continuance of any Event of Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying
Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent. 

Section 2.05 Lists of Holders of Notes. The Trustee shall preserve in as current a form as is reasonably practicable the most
recent list available to it of the names and addresses of Holders of Notes. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee at least five (5) Business Days before each Interest Payment Date and at such
other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Notes. 

  
 -31-









 Section 2.06 Transfer and Exchange. 

(a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Note is presented to a
Registrar with a request to register a transfer thereof or to exchange such Note for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided,
however, that every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form in the form included in Exhibit A, and completed in a manner satisfactory to the
Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Note for registration of transfer or exchange at an office or agency maintained
pursuant to Section 2.03, the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate Notes of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charges
or fees, except that the Company or the Registrar may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge that may be imposed in relation thereto, provided that this sentence shall not apply to
any transfer or exchange pursuant to Section 2.10, 3.06, 3.08, 4.15 or 9.05. 
 (b) Neither the Company, any Registrar nor
the Trustee shall be required to exchange or register a transfer of (1) any Notes for a period of 15 days next preceding mailing of a notice of Notes to be redeemed, or (2) any Notes or portions thereof selected or called for redemption
(except, in the case of redemption of a Note in part, the portion thereof not to be redeemed). 
 (c) All Notes issued upon any
transfer or exchange of Notes shall be valid and legally binding obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Notes surrendered upon such transfer or exchange. 

(d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such information as the Trustee may reasonably
require in connection with the delivery by such Registrar of Notes upon transfer or exchange of Notes. 
 Section 2.07
Replacement Notes. 
 (a) If any mutilated Note is surrendered to the Company, a Registrar or the Trustee, or the Company,
a Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as may be required by them
to save each of them harmless from any loss that any of them may suffer as a result of the replacement of such Note, then, in the absence of notice to the Company, such Registrar or the Trustee that such Note has been acquired by a bona fide
purchaser, the Company shall execute, and upon delivery of a Company Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and
principal amount, bearing a number not contemporaneously outstanding. 

  
 -32-









 (b) If any such mutilated, destroyed, lost or stolen Note has become or is about to become
due and payable, or is about to be purchased or redeemed by the Company pursuant to Article III or Section 4.10 or 4.15, the Company in its discretion may, instead of issuing a new Note, pay, redeem or purchase such Note, as the case may
be. 
 (c) Upon the issuance of any new Notes under this Section 2.07, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 

(d) Every new Note issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an
original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder. 
 (e) The provisions of this Section 2.07 are (to the extent lawful)
exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 
 Section 2.08 Outstanding Notes. 
 (a) Notes outstanding at any time are
all Notes authenticated by the Trustee, except for those canceled by it, those redeemed or purchased pursuant to Article III or Section 4.10 or 4.15, those delivered to the Trustee for cancellation and those described in this
Section 2.08 as not outstanding. 
 (b) If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding
unless the Company receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. 
 (c) If a Paying
Agent (other than the Company or an Affiliate of the Company) holds in respect of the outstanding Notes on a Redemption Date, Purchase Date, Change of Control Payment Date or the Final Maturity Date money sufficient to pay the principal of and
accrued interest on the Notes (or portions thereof) payable on that date, then on and after such Redemption Date, Purchase Date, Change of Control Payment Date or Final Maturity Date, as the case may be, such Notes (or portions thereof, as the case
may be) shall cease to be outstanding and interest on them shall cease to accrue, provided that if such Notes are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision thereof satisfactory to
the Trustee has been made. 
 (d) Subject to the restrictions contained in Section 2.09, a Note does not cease to be
outstanding because the Company or an Affiliate of the Company holds the Note. 
 Section 2.09 Treasury Notes. In
determining whether the Holders of the required principal amount of Notes have concurred in any notice, direction, waiver or consent, Notes owned by the Company or any other obligor on the Notes or by any Affiliate of the Company or of such other
obligor shall be disregarded, except that, for purposes of determining whether the 

  
 -33-









 
Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Notes which a Trust Officer of the Trustee with responsibility for this Indenture actually knows are
so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the
pledgee is not the Company or any other obligor on the Notes or any Affiliate of the Company or of such other obligor. 

Section 2.10 Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and execute, and, upon
receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes.
Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Notes in exchange for temporary Notes. 
 Section 2.11 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee or its agent any Notes
surrendered to them for transfer, exchange, redemption, purchase or payment. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Notes surrendered for transfer, exchange, redemption, purchase, payment or
cancellation and shall dispose of the cancelled Notes in accordance with its customary procedures or deliver the canceled Notes to the Company. All Notes which are redeemed, purchased or otherwise acquired by the Company or any of its Subsidiaries
prior to the Final Maturity Date pursuant to Article III or Section 4.10 or 4.15 shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Notes. 

Section 2.12 Additional Transfer and Exchange Requirements. 

(a) A Global Note may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor
thereof, and no such transfer to any such other Person may be registered, provided that the foregoing shall not prohibit any transfer of a Note that is issued in exchange for a Global Note but is not itself a Global Note, subject as
applicable to the provisions of Section 2.12(d). No transfer of a Note to any Person shall be effective under this Indenture or the Notes unless and until such Note has been registered in the name of such Person. Notwithstanding any other
provisions of this Indenture or the Notes, transfers of a Global Note, in whole or in part, shall be made only in accordance with this Section 2.12. 
 (b) Whenever any Note other than a Global Note is presented or surrendered for registration of transfer or in exchange for a Note registered in a name other than that of the Holder, such Note must be
accompanied by an assignment form in substantially the form set forth in Exhibit A, dated the date of such surrender and signed by the Holder of such Note. The Registrar shall not be required to accept for such registration of transfer or
exchange any such Note not so accompanied by a properly completed assignment form. As used in this Section 2.12, the term “transfer” encompasses any sale, pledge, transfer, exchange, hypothecation or other disposition of any Note.


  
 -34-









 (c) The provisions below shall apply to Global Notes: 

(1) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee
thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Note shall constitute a single Note for purposes of this Indenture. 

(2) Notwithstanding any other provisions of this Indenture or the Notes, a Global Note shall not be exchanged in whole or
in part for a Note registered, and no transfer of a Global Note in whole or in part shall be registered, in the name of any Person other than the Depositary or one or more nominees or any successor thereof, provided that a Global Note may be
exchanged for one or more Certificated Notes registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such
Global Note or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days after receiving such notice or becoming aware that the
Depositary has ceased to be a “clearing agency,” or (B) an Event of Default has occurred and is continuing with respect to the Notes and the Depositary requests the issuance of Certificated Notes. Any Global Note exchanged pursuant to
subclause (A) above shall be so exchanged in whole and not in part, and any Global Note exchanged pursuant to subclause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Except as specifically
provided in the preceding sentence, any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note, provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a
nominee thereof shall not be a Global Note. 
 (3) Notes issued in exchange for a Global Note or any portion
thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in
such authorized denominations as the Depositary shall designate. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Note to be exchanged in part, either such Global
Note shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so
exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Note issuable on such exchange to or upon the order of the Depositary or an
authorized representative thereof. 
 (4) Subject to clause (6) of this Section 2.12(c), the registered
Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. 

  
 -35-









 (5) In the event of the occurrence of any of the events specified in
clause (2) of this Section 2.12(c), the Company will promptly make available to the Trustee a reasonable supply of Certificated Notes in definitive, fully registered form, without interest coupons. 

(6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any
agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee
from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent
Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Note. 
 (7) At such time as all interests in a Global Note have been redeemed, cancelled or exchanged for Notes in certificated form, such Global Note shall, upon receipt thereof, be cancelled by the Trustee in
accordance with standing procedures and instructions existing between the Depositary and the Notes Custodian, subject to Section 2.11 of this Indenture. At any time prior to such cancellation, if any interest in a Global Note is redeemed,
canceled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Notes Custodian, be appropriately reduced, and
an endorsement shall be made on such Global Note, by the Trustee or the Notes Custodian, at the direction of the Trustee, to reflect such reduction. 
 (d) In addition to any other requirement of this Section 2.12, the following requirements shall apply with respect to the registration of any proposed transfer of a Restricted Note: 

(1) the transferor and transferee have delivered to the Trustee and the Company such certifications and legal opinions as
may be reasonably requested by the Trustee and the Company relating to compliance with applicable securities laws; and 
 (2) the Restricted Notes so transferred shall bear the Private Placement Legend, unless (i) there is delivered to the Trustee and the Company an Opinion of Counsel reasonably satisfactory to the
Company to the effect that neither such legend nor the related restrictions on transfer are required to maintain compliance 

  
 -36-









 
with the provisions of the Securities Act or (ii) such Restricted Note has been offered and sold pursuant to an effective registration statement under the Securities Act. 

(e) By its acceptance of any Restricted Note, each Holder of such a Restricted Note acknowledges the restrictions on transfer of such
Restricted Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Restricted Note only as provided in this Indenture. 
 (f) Each Restricted Note may be exchanged or transferred for a beneficial interest in a Global Note after the requisite holding period permitting resale of the Note without limitation or restriction of
any kind under Rule 144 under the Securities Act in a transaction meeting the requirements of Rule 144 under the Securities Act. For any such exchange or transfer, the Holder of the Restricted Notes will provide the Trustee, the Company and the
Company’s counsel contemplated below with reasonable assurance that such Restricted Notes can be exchanged or transferred pursuant to Rule 144 under the Securities Act, including customary representations reasonably requested by the Trustee and
the Company with respect to such Holder’s holding period of its Restricted Notes and with respect to a determination whether such Holder is an Affiliate of the Company. The Holder of the Restricted Notes will also provide the Trustee and the
Company such information reasonably requested by the Trustee and the Company as being required by the Depositary to effect such exchange or transfer in accordance with the Applicable Procedures. 

If any Opinion of Counsel for such exchange or transfer is requested by the Trustee or the Company, the Company shall use its best
efforts to cause its counsel to deliver such Opinion of Counsel. 
 (g) In addition to any other requirement of this
Section 2.12, the following requirements shall apply with respect to the proposed exchange or transfer of any Restricted Note for a beneficial interest in a Global Note other than pursuant to Section 2.12(f) above: 

(1) there is delivered to the Trustee and the Company an Opinion of Counsel reasonably satisfactory to the Company to the
effect that neither the Private Placement Legend nor the related restrictions on transfer are required to maintain compliance with the provisions of the Securities Act; and 

(2) there is delivered to the Trustee and the Company such information reasonably requested by the Trustee and the Company
as being required by the Depositary to effect such exchange or transfer in accordance with the Applicable Procedures. 
 (h) To
facilitate an exchange or transfer of Restricted Notes for beneficial interests in a Global Note bearing the same CUSIP number as the Unrestricted Note, the Company and Trustee shall take all necessary actions reasonably requested by the Holder of
the Restricted Note, including cancelling the Certificated Note and increasing the aggregate principal amount of the Global Note through the Applicable Procedures, upon the Holder of the Restricted Note’s satisfaction of the provisions set
forth in either Section 2.12(f) or 2.12(g) above. 

  
 -37-









 (i) All Global Notes and Certificated Notes issued upon any exchange or registration of
transfer of Global Notes or Certificated Notes shall, upon execution by the Company and authentication by the Trustee, be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the
Global Notes or Certificated Notes surrendered upon such exchange or registration of transfer. 
 (j) The Registrar shall retain
copies of all letters, notices and other written communications received pursuant to Section 2.12 as long as there are any Notes outstanding. The Company shall have the right to inspect and make copies of all such letters, notices or other
written communications at any reasonable time upon the giving of reasonable written notice to the Registrar. 
 The Trustee
shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any
transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 The Trustee shall have no responsibility for the actions or omissions of the Depositary, or the accuracy of the books and records of the Depositary. 

Section 2.13 CUSIP Numbers. The Company in issuing the Notes may use one or more “CUSIP” numbers (if then generally
in use), and, if so, the Trustee shall use the “CUSIP” number or numbers in notices of redemption or purchase as a convenience to Holders, provided that any such notice may state that no representation is made as to the correctness
of such number or numbers either as printed on the Notes or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or purchase
shall not be affected by any defect in or omission of such number or numbers. The Company will promptly notify the Trustee in writing of any change in a “CUSIP” number. 

ARTICLE III 

REDEMPTION AND PURCHASE 
 Section 3.01 Optional Redemption. 
 (a) The Company may at any time on
any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at a redemption price (the “Redemption Price”) equal to 100% of the principal amount of the Notes redeemed, plus the
Applicable Premium as of, and accrued and unpaid interest on the principal amount of the Notes redeemed to, the Redemption Date, subject to the rights of Holders of Notes on the relevant Regular Record Date to receive interest due on the relevant
Interest Payment Date as and to the extent provided in Section 3.05. 

  
 -38-









 (b) Except pursuant to Section 3.01(a), the Notes will not be redeemable at the
Company’s option prior to the Final Maturity Date. 
 (c) If the Company elects to redeem Notes pursuant to this
Section 3.01, it shall notify the Trustee in writing at least 15 days prior to the date it sends the redemption notice specified in Section 3.03 to the Holders (unless a shorter period shall be satisfactory to the Trustee), of the
Redemption Date and the principal amount of Notes to be redeemed. 
 Section 3.02 Selection of Notes to be Redeemed.

 (a) If less than all of the Notes are to be redeemed, unless the Applicable Procedures specify otherwise, the Trustee shall
select the Notes to be redeemed within five Business Days after it receives the notice described in Section 3.01(c). The Trustee shall make the selection from the Notes outstanding and not previously called for redemption by lot, or in its
discretion, on a pro rata basis or by another method that the Trustee considers fair and reasonable (so long as such method is not prohibited by the rules of any stock exchange or market on which the Notes are listed and the Trustee has knowledge of
such listing). Notes in denominations of $2,000 principal amount may only be redeemed in whole. The Trustee may select for redemption portions (equal to $2,000 principal amount or any integral multiple of $1,000 in excess thereof) of the principal
amount of Notes that have denominations larger than $2,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly of the Notes or
portions of Notes to be redeemed. 
 (b) In the event of any redemption in part, the Company shall not be required to
(i) issue, register the transfer of or exchange any Note during a period beginning at the opening of business 15 days before any selection of Notes for redemption and ending at the close of business on the earliest date on which the relevant
notice of redemption is deemed to have been given to all Holders of Notes to be redeemed, or (ii) register the transfer or exchange of any Note so selected for redemption, in whole or in part, except the unredeemed portion of any security being
redeemed in part. 
 Section 3.03 Notice of Redemption. 

(a) At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed a notice of
redemption to each Holder of Notes to be redeemed at such Holder’s address as it appears on the Registrar’s books. 

(b) The notice shall identify the Notes (including CUSIP number) to be redeemed and shall state: 

(1) the Redemption Date; 
 (2) the Redemption Price; 
 (3) the name and address of each Paying
Agent; 

  
 -39-









 (4) that Notes called for redemption must be presented and surrendered to a
Paying Agent to collect the Redemption Price; 
 (5) that, unless the Company has failed to make the payment of
such Redemption Price which is due and payable, interest will cease to accrue on and after the Redemption Date; 

(6) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after
the Redemption Date, upon presentation and surrender of such Note, a new Note or Notes in aggregate principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder of such Note or, if requested by such Holder,
transferred by book-entry upon cancellation of the original Note; 
 (7) if Certificated Notes are outstanding
and fewer than all the outstanding Notes are to be redeemed, the certificate number and the principal amounts of the particular Notes to be redeemed; and 
 (8) if such notice is provided by the Trustee, that no representation is made as to the correctness or accuracy of the CUSIP number listed in such notice. 

(c) If any of the Notes to be redeemed are in the form of a Global Note, then the Company shall modify such notice to the extent
necessary to accord with the procedures of the Depositary applicable to redemptions. At the Company’s written request, which request shall (1) be irrevocable once given and (2) set forth all relevant information required by
clauses (1) through (7) of Section 3.03(b), the Trustee shall give the notice of redemption to each Holder in the Company’s name and at the Company’s expense; provided, however, that in all cases, the text of
such notice of redemption shall be prepared by the Company; and provided further that the Company submit to the Trustee such written request, along with an Officers’ Certificate, at least five Business Days prior to the date by which
such notice of redemption must be given to the Holders in accordance with this Section 3.03 (unless a shorter period should be satisfactory to the Trustee). 
 Section 3.04 Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the
Redemption Date and at the Redemption Price stated in the notice. On or after the Redemption Date and upon presentation and surrender to a Paying Agent, Notes called for redemption shall be paid at the Redemption Price. 

Section 3.05 Deposit of Redemption Price. 
 (a) Prior to 12:00 p.m. (noon), New York City time, on the Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company acts as Paying Agent, shall segregate and hold in trust)
an amount of money (in immediately available funds if deposited on such Redemption Date) sufficient to pay the Redemption Price payable upon redemption on all Notes to be redeemed on that date, other than Notes or portions thereof called for
redemption on that date which have been delivered by the Company to the Trustee for cancellation. The Paying Agent shall as promptly as practicable return to the Company any money not required for that purpose because of the cancellation of Notes
or, if such money is then held by the Company in trust and is not required for such purpose, it shall be discharged from the trust. 

  
 -40-









 (b) If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay
the Redemption Price of any Note for which a notice of redemption has been tendered and not withdrawn in accordance with this Indenture then, on the Redemption Date, such Note will cease to be outstanding, whether or not the Note is delivered to the
Paying Agent, and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Redemption Price as aforesaid). 
 (c) If a Note is redeemed on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest to the Redemption Date shall be paid on such Interest
Payment Date to the Person in whose name such Note was registered at the close of business on such Regular Record Date, and no additional interest will be payable to the Holder who tenders such Note for redemption. 

(d) If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply
with Section 3.05(a), interest at the rate provided in the Notes shall be paid on the unpaid principal called for redemption and, to the extent lawful, on any unpaid interest accrued to the Redemption Date on such unpaid principal, in each case
from the Redemption Date to the date such principal or interest (as the case may be) is paid. 
 Section 3.06 Notes
Redeemed in Part. Upon presentation and surrender of a Note that is redeemed in part, the Company shall execute and the Trustee shall authenticate and mail or deliver (or cause to be transferred by book entry) to the Holder, at the expense of
the Company, a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 
 Section 3.07
Purchase of Notes in Open Market. The Company shall, in accordance with Section 2.11, surrender any Note purchased by the Company pursuant to this Article III to the Trustee for cancellation. Any Notes surrendered to the Trustee for
cancellation may not be reissued or resold by the Company and will be canceled promptly in accordance with Section 2.11. The Company may repurchase Notes in open market and negotiated transactions. 

Section 3.08 Offer to Purchase by Application of Excess Proceeds. 

In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an
“Asset Sale Offer”), it will follow the procedures specified below. 
 The Asset Sale Offer shall be made to all
Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes and contains provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets.
The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement or such longer period as may be required by applicable law (the “Offer Period”). No later than three Business Days after the
termination of the Offer Period (the “Purchase Date”), the Company will apply all of the Offer Amount to the purchase, prepayment or redemption of Notes and such other pari passu Indebtedness on a pro rata basis based on the


  
 -41-









 
principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or
an integral multiple of $1,000 in excess thereof, will be purchased) or, if the aggregate principal amount of the Notes and other pari passu Indebtedness that has been tendered or required to be prepaid or redeemed in response to the Asset Sale
Offer is less than the Offer Amount, all Notes and other pari passu Indebtedness tendered or required to be prepaid or redeemed. 
 If the Purchase Date is on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest to the Purchase Date will be paid on such Interest Payment
Date to the Person in whose name a Note is registered at the close of business on such Regular Record Date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 

Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the Trustee and each of the
Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders and holders of other
pari passu Indebtedness. The notice, which will govern the terms of the Asset Sale Offer, will state: 
 (1) that the Asset Sale
Offer is being made pursuant to this Section 3.08 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase price and the Purchase Date; 
 (3) that any
Note not tendered or accepted for payment will continue to accrue interest; 
 (4) that, unless the Company defaults in making
such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof;

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

  
 -42-









 (8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness
surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased, prepaid or redeemed on a pro rata basis based on the principal amount of Notes and such other pari
passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and 

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered (or transferred by book-entry transfer). 
 On or before the Purchase Date, the Company will, to the
extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and other pari passu Indebtedness or portions thereof tendered or required to be prepaid or redeemed pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered or required to be prepaid or redeemed, all Notes and other pari passu Indebtedness tendered or required to be prepaid or redeemed, and will deliver or cause to be delivered to the Trustee the Notes
properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.08. The Company, the Depositary or the Paying
Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the
Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a
principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on
the Purchase Date.

Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Company or a Subsidiary thereof) holds by 12:00 p.m. (noon), New York City time, on that date money, deposited by
or on behalf of the Company in immediately available funds, designated for and sufficient to make such payment. Accrued and unpaid interest on any Note that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall

 -43-









 (b) Payment of the principal of and interest on the Notes shall be made at the office or
agency of the Company maintained for that purpose at the Corporate Trust Office of the Trustee in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be made through the Paying Agent by check mailed to the address of the Person entitled thereto as such address appears in the Registrar; provided
further that a Holder of Notes in an aggregate principal amount in excess of $2.0 million will be paid interest on such Notes by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire

to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 13.02. 

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered
for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency.

provided in the penultimate sentence of Section 4.03(b). 
 (e) Delivery of all reports, information and documents referred
to in clauses (1) and (2) of Section 4.03(a) to the Trustee is for informational purposes only, and the Trustee’s receipt of such reports, information or documents shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

 Section 4.04 Compliance Certificates. The Company and each Guarantor (to the extent that such Guarantor is

 Section 4.06 Stay, Extension and Usury Laws. The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company or a Guarantor from paying all or any portion of the principal of or accrued but unpaid
interest, if any, on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and the Company and each of the Guarantors (to the extent it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

 (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or 

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

 (b) The restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by
reason of: 
 (1) agreements governing Existing Indebtedness and Credit Facilities as in effect on the date of
this Indenture and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements, provided that (i) the amendments, restatements, modifications, renewals, supplements,
refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such encumbrances and restrictions than those contained in those agreements on the date of this Indenture or (ii) the encumbrances
and restrictions in the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings will not materially adversely affect the Company’s ability to pay the principal of and interest on the Notes as and
when due; 
 (2) the Note Documents; 

(3) agreements governing other Indebtedness (other than intercompany Indebtedness between or among the Company and any of
its Restricted Subsidiaries) permitted to be incurred under Section 4.09 hereof and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements, provided that the
encumbrances and restrictions therein will not materially adversely affect the Company’s ability to pay the principal of and interest on the Notes as and when due; 

(4) applicable law, rule, regulation or order; 

(5) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted
Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in 

  
 -51-









 
connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or
the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; 

(6) customary non-assignment provisions in contracts; 

(7) in the case of clause (3) of Section 4.08(a) hereof, any encumbrance or restriction:

of the nature described in clauses (1) through (3) of Section 4.08(a) hereof on that Restricted Subsidiary pending its sale or other disposition; 
 (9) Permitted Refinancing Indebtedness, provided that the encumbrances and restrictions contained in the agreements governing such Permitted Refinancing Indebtedness (i) are not materially
more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced or (ii) will not materially adversely affect the Company’s ability to pay the principal of and interest in the Notes as
and when due; 
 (10) Liens permitted to be incurred under Section 4.12 hereof that limit the right of the
debtor to dispose of the assets subject to such Liens; 
 (11) provisions limiting the disposition or

 (12) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

 Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Stock and
Preferred Stock. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise (collectively, “incur”), with respect to any Indebtedness (including Acquired Debt) or issue any Disqualified
Stock, and the Company will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company and the Guarantors may incur (1) Secured Debt (including Acquired Debt) if the
Secured Leverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Secured Debt is incurred would have been less
than 2.5 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Secured Debt had been incurred at the beginning of such four-quarter period and (2) unsecured Indebtedness,
provided that such unsecured Indebtedness has a final maturity date not earlier than 180 days after the Final Maturity Date and the terms, covenants and rates (including interest rates and fees) of such unsecured Indebtedness are commercially
reasonable at the time of incurrence thereof. 
 (b) The provisions of Section 4.09(a) hereof will not prohibit the
incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
 (1)
Indebtedness of the Company or any Guarantor incurred pursuant to one or more Credit Facilities (including the Credit Agreement) in an aggregate principal amount outstanding at any given time not to exceed $35 million (less (x) the amount
of any permanent repayments of such Indebtedness pursuant to clause (1) of the second paragraph of Section 4.10 hereof, and (y) the aggregate amount outstanding at any given time of any Hedging Obligations and Banking Services
Obligations that constitute Priority Lien Obligations); 
 (2) the incurrence by the Company and its Restricted
Subsidiaries of the Existing Indebtedness; 
 (3) the incurrence by the Company and the Guarantors of
Indebtedness represented by the Notes and the Note Guaranties; 
 (4) the incurrence by the Company or any of its
Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price, construction,
installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund,
refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed at any time outstanding the maximum amount permitted by the Credit Agreement as in effect on January 12, 2012, provided
that the principal amount of any Indebtedness permitted under this clause (4) did not in each case at the time of incurrence exceed the Fair Market Value (as determined in good faith by 

  
 -53-









 
the Board of Directors or, if the principal amount of such Indebtedness is $5.0 million or less, the Chief Financial Officer of the Company) of the acquired, installed or constructed asset
or improvement so financed; 
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of
Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be
incurred under Section 4.09(a) hereof or clauses (2), (3), (4) or (5) of this Section 4.09(b); 
 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however,
that (i) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations
then due with respect to the Notes, in the case of the Company, or the Note Guaranty, in the case of a Guarantor, and (ii) if the payee of such Indebtedness is the Company or any Guarantor, such Indebtedness shall become part of the Collateral;

 (7) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary
course of business and not for speculative purposes; 
 (8) the guarantee by the Company or any of the Guarantors
of Indebtedness of the Company or a Restricted Subsidiary of the Company to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this Section 4.09, provided that if the Indebtedness being
guaranteed is subordinated to the Notes or any Note Guaranty, then the guarantee must be subordinated to the same extent as the Indebtedness guaranteed; 
 (9) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of (i) unsecured service fees payable to any Subsidiary of the Company in the ordinary course of
business, (ii) self-insurance obligations or bid, appeal, reimbursement, performance, surety and similar bonds and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business and any Guaranties or
letters of credit functioning as or supporting any of the foregoing bonds or obligations and (iii) workers’ compensation claims in the ordinary course of business; 

(10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a
bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the
Company or any of its Restricted Subsidiaries providing for indemnification, or other purchase price adjustments or similar 

  
 -54-









 
obligations, in each case, incurred or assumed in connection with the disposition of any business or assets of the Company or any Restricted Subsidiary of the Company or of any Capital Stock of a
Subsidiary of the Company, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such
disposition; 
 (12) Indebtedness of the Company or any Restricted Subsidiary with respect to the financing of
insurance premiums; and 
 (13) Indebtedness to the extent the net proceeds thereof are promptly deposited to
defease the Notes or to satisfy and discharge this Indenture. 
 The Company will not incur, and will not permit any Guarantor
to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment
to the Notes or the applicable Note Guaranty, as the case may be, on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness
of the Company or any Guarantor solely by virtue of being unsecured or by virtue of being secured on a junior priority basis. 

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more
than one of the categories of Permitted Debt described in clauses (2) through (13) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify such item of Indebtedness on the
date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with such clauses or paragraph of this Section 4.09. The accrual of interest or preferred stock dividends, the accretion or
amortization of original issue discount, and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles and
the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred or
Disqualified Stock for purposes of this Section 4.09. For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated
in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness
that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 

The amount of any Indebtedness outstanding as of any date will be: 

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;


  
 -55-









 (2) in respect of Hedging Obligations, the net obligations of the specified
Person under the applicable Hedge Agreement that would be due and payable as of such date if such Hedge Agreement were terminated (as customarily determined); 
 (3) in respect of contingent obligations, the maximum liability upon the occurrence of the contingency giving rise to the obligations; 

(4) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

 (A) the Fair Market Value of such assets at the date of determination; and 

(B) the principal amount of the Indebtedness of the other Person; and 

(5) the principal amount of the Indebtedness, in the case of any other Indebtedness. 

Section 4.10 Asset Sales. The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an
Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration
at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and 

(2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the
form of cash or Cash Equivalents. For purposes of this clause (2), each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any Note Guaranty) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases the Company or such Restricted Subsidiary from or indemnifies the
Company or such Restricted Subsidiary against further liability; and 
 (B) any securities, notes or other
obligations received by the Company or any such Restricted Subsidiary from such transferee that are contemporaneously, subject to ordinary settlement periods, converted by the Company or such Restricted Subsidiary into cash, to the extent of the
cash received in that conversion. 

  
 -56-









 Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company
(or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds: 
 (1) to permanently
repay Priority Lien Debt and other outstanding Priority Lien Obligations, provided that, if such Priority Lien Debt is revolving credit Indebtedness, there is a corresponding permanent reduction in the commitments with respect thereto;

 (2) to purchase, redeem or otherwise acquire any Outstanding 3.25% Notes, provided that such purchase,
redemption or other acquisition is permitted under Section 4.07 hereof; 
 (3) to make capital expenditures
for the benefit of the business of the Company or any Restricted Subsidiary of the Company; or 
 (4) to acquire
other assets that are not classified as current assets under GAAP and that are used or useful in the business of the Company or any Restricted Subsidiary of the Company. 
 Notwithstanding the foregoing, the Net Proceeds of any Asset Sale by the Company or any Guarantor may be used to make capital expenditures or purchase assets for the benefit of a Restricted Subsidiary of
the Company that is not a Guarantor in satisfaction of the foregoing clause (3) or (4) only if the Investment of such Net Proceeds by the Company or such Guarantor in such Restricted Subsidiary would be permitted under clause (y) of
Section 4.07(a) hereof, clause (12) of Section 4.07(b) hereof, or clause (15) or (16) of the definition of Permitted Investments. 
 Pending the final application of any Net Proceeds, the Company (or the applicable Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any
manner that is not prohibited by this Indenture. 
 Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the second paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, within five days thereafter, the Company will make an Asset Sale Offer
to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes and contains provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of
assets, in accordance with Section 3.08 hereof, to purchase, prepay or redeem the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased, prepaid or redeemed out of the Excess Proceeds after deducting
from such Excess Proceeds all accrued and unpaid interest on the Notes and such other pari passu Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection with such purchase, prepayment or redemption (the
“Offer Amount”). The offer price in any Asset Sale Offer will be equal to 100% of the aggregate principal amount purchased, prepaid or redeemed, plus accrued and unpaid interest on such principal amount to the Purchase Date, subject to the
rights of Holders of Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date as and to the extent provided in Section 3.08 hereof, and will be payable in cash. If any


  
 -57-









 
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal
amount of Notes and other pari passu Indebtedness tendered in or required to be prepaid or redeemed in connection with such Asset Sale Offer exceeds the Offer Amount, the Notes and other pari passu Indebtedness will be purchased, prepaid or redeemed
on a pro rata basis, based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in
excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 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 each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.08 hereof or this Section 4.10, the Company will
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.08 hereof or this Section 4.10 by virtue of such compliance. 

Section 4.11 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”),
unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant
Restricted Subsidiary than those that would have been obtained by the Company or such Restricted Subsidiary in a comparable transaction on an arm’s-length basis with a Person that is not an Affiliate of the Company; and 

(2) the Company delivers to the Trustee: 

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $5.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a) and
that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an opinion as to the fairness to the Company or
such Restricted Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 

  
 -58-









 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will
not be subject to the provisions of Section 4.11(a) hereof: 
 (1) any employment agreement, change in
control or severance agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments
pursuant thereto; 
 (2) transactions between (a) the Company or any Restricted Subsidiary of the Company
that is a Guarantor or a Pledged Restricted Subsidiary and any other Restricted Subsidiary of the Company that is a Guarantor or a Pledged Restricted Subsidiary, or (b) any Restricted Subsidiary of the Company that is not a Guarantor or a
Pledged Restricted Subsidiary and any other Restricted Subsidiary of the Company that is not a Guarantor or a Pledged Restricted Subsidiary; 
 (3) the provision of customer support services by any Restricted Subsidiary of the Company that is not a Guarantor or a Pledged Restricted Subsidiary to the Company or any Restricted Subsidiary of the
Company that is a Guarantor or a Pledged Restricted Subsidiary, and the payment for such services (provided that all such payments by the Company or any Restricted Subsidiary of the Company that is a Guarantor or a Pledged Restricted
Subsidiary to any Restricted Subsidiary of the Company that is not a Guarantor or a Pledged Restricted Subsidiary may not exceed $4.0 million in the aggregate during any single fiscal year of the Company), in the ordinary course of business
consistent with past practice; 
 (4) transactions with a Person (other than an Unrestricted Subsidiary of the
Company) that is an Affiliate of the Company solely because such Person is a Joint Venture; 
 (5) payment of
reasonable and customary fees of directors of the Company or any of its Restricted Subsidiaries; 
 (6) any
issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company; 
 (7)
Restricted Payments (or any transactions, other than Permitted Investments, that would be Restricted Payments but for an exclusion from the definition thereof) that do not violate Section 4.07 hereof; 

(8) loans or advances to directors, officers and employees in the ordinary course of business; 

(9) reimbursements of directors, officers and employees for moving, entertainment and travel expenses, drawing accounts
and other business expenditures, in each case in the ordinary course of business of the Company or any of its Restricted Subsidiaries; 

  
 -59-









 (10) indemnities of officers, directors and employees of the Company or any
Restricted Subsidiary of the Company consistent with applicable charter, by-law or statutory provisions; 
 (11)
transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture, provided that such transactions are
on terms not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not
an Affiliate of the Company; and 
 (12) transactions between the Company or any Restricted Subsidiary of the
Company and any Person, a director of which is also a director of the Company or any direct or indirect parent company of the Company, and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted
Subsidiary of the Company; provided, however, that such director shall abstain from voting as a director of the Company or such direct or indirect parent company, as the case may be, on any matter involving such other Person.

 Section 4.12 Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume or suffer to exist any Lien of any kind upon any of its property or assets, including any income or profits therefrom, whether owned on the date of this Indenture or acquired after that date, securing any
Indebtedness, except Permitted Liens. 
 Section 4.13 Business Activities. The Company will not, and will not permit
any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 

Section 4.14 Maintenance of Corporate Existence. Subject to Article V, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as
the same may be amended from time to time) of the Company or such Restricted Subsidiary, and (ii) the material rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided,
however, that neither the Company nor any Restricted Subsidiary of the Company shall be required to maintain or preserve any such rights, licenses or franchises or, in the case of any such Restricted Subsidiary, its existence, if the Board of
Directors shall determine that the maintenance or preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof would not be adverse in any
material respect to the Holders of the Notes. 

  
 -60-









 Section 4.15 Offer to Repurchase Upon Change of Control. 

(a) Upon the occurrence of a Change of Control, the Company will make an offer (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 that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus
accrued and unpaid interest, if any, on such principal amount to the date of purchase, subject to the rights of Holders of Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date as and to the extent
provided below (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and
stating: 
 (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all
Notes tendered will be accepted for payment; 
 (2) the purchase price and the purchase date, which shall be no
earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not tendered will continue to accrue interest; 

(4) 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; 

(5) 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; 
 (6) that Holders will be entitled to withdraw
their election if the Paying Agent receives, not later than the close of business on the 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 its election to have the Notes purchased; and 
 (7) 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. 
 If the Change of Control Payment
Date is on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest to the Change of Control Payment Date will be paid on such Interest Payment Date to the Person in whose name a Note is
registered at the close of business on such Regular Record Date, and no additional interest will be payable to Holders who tender Notes pursuant to the Change in Control. 

  
 -61-









 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. To the extent that the provisions of any securities laws
or regulations conflict with the provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such
compliance. 
 (b) On or before the Change of Control Payment Date, the Company will, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

 (2) 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 
 (3) 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 purchased by the Company. 
 The Paying Agent will promptly mail (but in any case not later than three 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 mail or 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. 
 (c) Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the
Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or
(2) notice of redemption has been given pursuant to Section 3.01 hereof, unless and until there is a default in payment of the applicable Redemption Price. 
 (d) Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a
definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 
 Section 4.16
Note Guaranties. 
 (a) If, after the date of this Indenture, the Company or any Restricted Subsidiary of the Company
forms or acquires any Domestic Subsidiary that is a Wholly Owned Restricted Subsidiary, then the Company will promptly (and in any event within 10 Business Days) after the date of formation or acquisition cause such Domestic Subsidiary to provide a
Note Guaranty pursuant to a supplemental indenture in substantially the form of Exhibit C attached hereto. 

  
 -62-









 (b) If, after the date of this Indenture, any Restricted Subsidiary of the Company that is
not a Guarantor guarantees or provides credit support for (other than by granting Liens on its assets) any Priority Lien Obligations, then the Company will promptly (and in any event within 10 Business Days) thereafter cause such Restricted
Subsidiary to provide a Note Guaranty pursuant to a supplemental indenture in substantially the form of Exhibit C attached hereto. 
 (c) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any Investment in any Person that is, or after the making of such Investment will be, a Restricted Subsidiary of
the Company that is not a Wholly Owned Restricted Subsidiary, unless (i) such Restricted Subsidiary is, or after the making of such Investment will be, a Guarantor, or (ii) such Investment is permitted under clause (y) of
Section 4.07(a) hereof, clause (12) of Section 4.07(b) hereof (without the ability of the Company to reallocate such Investment as permitted by the last paragraph of Section 4.07), or clause (14), (15) or
(16) of the definition of Permitted Investment. 
 Section 4.17 Designation of Restricted and Unrestricted
Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default or Event of Default. If a Restricted Subsidiary is designated as an
Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the
time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be
permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving
effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the
preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the
Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant. 

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company,
provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if
(1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in
existence following such designation.

 Section 4.18 Additional Collateral. 

(a) If, after the date of this Indenture, the Company or any Restricted Subsidiary of the Company forms or acquires any Domestic
Subsidiary that is a Wholly Owned Restricted Subsidiary, then the Company will promptly (and in any event within 10 Business Days) after the date of formation or acquisition cause such Domestic Subsidiary to grant a Lien on substantially all of its
assets (other than Excluded Assets) to secure the Note Obligations, which Lien shall be subject to the Intercreditor Agreement, by executing and delivering to the Collateral Agent a Second Lien Security Agreement Joinder, and to otherwise comply
with the terms of the Second Lien Security Agreement regarding the perfection of such Liens. 
 (b) If, after the date of this
Indenture, the Priority Lien Debt is secured by Liens on any assets of the Company or its Restricted Subsidiaries not theretofore subject to a Priority Lien (other than Rule 3-16 Excluded Assets, but including any other Excluded Assets), the
Company shall promptly take or cause its Restricted Subsidiaries to take such action as may be reasonably required to grant to the Collateral Agent (or a co-collateral agent) a second priority Lien (subject to Priority Liens and Permitted Prior
Liens) on such assets to secure the Note Obligations. 
 (c) On or before the earlier of (i) August 31, 2012 or
(ii) the date that is five months after the closing of the Company’s issuance of the Notes, the Company shall, with respect to all real property that is owned by the Company on the date of this Indenture and located in the United States
(other than the Development Center and the Learning Center), deliver to the Collateral Agent the following documents and instruments: 
 (1) fully executed counterparts of a mortgage or deed of trust encumbering such real property in favor of the Collateral Agent (or a co-collateral agent), as agent for the benefit of the holders of the
Note Obligations (which mortgage or deed of trust may also secure the Priority Lien Obligations), duly executed and delivered by the Company, as mortgagor (which mortgage or deed of trust shall secure Indebtedness in a principal amount not to exceed
the Fair Market Value of the real property purported to be covered thereby), together with evidence of the completion, or reasonably satisfactory arrangements for the completion, of all recordings and filings of such mortgage or deed of trust (and
payment of any taxes or fees in connection therewith) as may be reasonably necessary to create a valid, perfected Lien against the real property purported to be covered thereby; 

(2) lender’s title insurance policies in favor of the Collateral Agent (or such co-collateral agent) with respect to
each such mortgage or deed of trust insuring that such mortgage or deed of trust constitutes a valid Lien on the real property described in such mortgage or deed of trust, subject only to Permitted Liens, together with evidence of the payment in
full of the premiums thereon; and 

  
 -64-









 (3) such affidavits that the title insurance company shall reasonably
request in connection with the issuance of the title policies referenced in clause (2) above. 
 (d) Upon the acquisition
by the Company or any Guarantor of any property that, upon such acquisition, will be subject to the Priority Liens, the Company or such Guarantor shall execute and deliver such Security Documents, if any, as shall be reasonably necessary to vest in
the Collateral Agent (or a co-collateral agent) a perfected second-priority security interest, subject to the Priority Liens and Permitted Prior Liens, in such property and to have such property added to the Collateral, and thereupon all provisions
of this Indenture relating to the Collateral shall be deemed to relate to such property to the same extent and with the same force and effect. 
 Section 4.19 Operating Leases. The Company will not, and will not permit any Guarantor to, enter into as lessee any lease of real or personal property (other than capital leases) if, after
giving effect thereto, rental payments of the Company and the Guarantors, on a consolidated basis, under all such leases would exceed the lesser of (i) $15.0 million per fiscal year in the aggregate, and (ii) the maximum amount
allowed under the Credit Agreement as in effect on January 12, 2012. 
 Section 4.20 Consolidated Total Assets.

 (a) The Company will not permit, as of the end of any fiscal quarter of the Company, the book value of the total assets of the
Company and the Guarantors on a consolidated basis to be less than 50% of the book value of the total assets of the Company and its Subsidiaries on a consolidated basis. 
 (b) The Company will not permit, as of the end of any fiscal quarter of the Company, the book value of the total assets of the Company, the Guarantors and the Pledged Restricted Subsidiaries on a
consolidated basis to be less than 90% of the book value of the total assets of the Company and its Subsidiaries on a consolidated basis. 
 (c) For purposes of the foregoing, the book value of any assets shall be the value at which those assets are carried on a balance sheet prepared in accordance with GAAP, and the phrase “on a
consolidated basis” means consolidation of the accounts of the Company and the Subsidiaries identified as consolidated with the Company for purposes of the foregoing without any elimination entries to remove the effects of intercompany
transactions between the Company or any such Subsidiary, on the one hand, and any Subsidiary of the Company that is not identified as consolidated with the Company for purposes of the foregoing, on the other hand. 

Section 4.21 Free Cash Flow. 
 (a) The Company will not permit the free cash flow of any Subsidiary of the Company that is not a Guarantor or a Pledged Restricted Subsidiary to be greater than $2.0 million per fiscal year of the
Company. 

  
 -65-









 (b) For purposes hereof, the “free cash flow” of any Subsidiary for any period
shall mean (i) the cash provided by such Subsidiary’s operating activities during such period, minus (ii) the capital expenditures of such Subsidiary for such period.

 (a) the Person (if other than the Company) formed by such consolidation, into which the Company is merged or which acquires by direct or indirect sale, assignment, conveyance, lease, transfer or other
disposition all or substantially all of the properties and assets of the Company and its Restricted Subsidiaries, taken as a whole, shall (i) be an entity organized and existing under the laws of the United States of America or any State

supplemental hereto, executed and delivered to the Trustee, the obligations of the Company under the Notes and this Indenture and (B) by supplements thereto, executed and delivered to the Collateral Agent, the obligations of the Company under

assets between or among the Company and its Restricted Subsidiaries or any merger or consolidation of the Company with or into one of its Restricted Subsidiaries. 
 Section 5.02 Successor Substituted. Upon any consolidation of the Company with, or merger of the Company into, any other Person or any sale, assignment, conveyance, lease, transfer or other

 -66-









 
Documents with the same effect as if such successor Person had been named as the Company herein and therein, and thereafter, except in the case of a lease and for obligations the predecessor
Person may have under a supplemental indenture or supplements to any Security Documents, the predecessor Person shall be relieved of all obligations and covenants under the Note Documents. 

ARTICLE VI 

DEFAULT AND REMEDIES 
 Section 6.01 Events of Default. 
 (a) An “Event of
Default” shall occur if: 
 (1) the Company shall fail to pay the Principal of any Note or any Redemption
Price when the same becomes due and payable, whether at the Final Maturity Date or upon redemption, repurchase or acceleration or otherwise; or 
 (2) the Company shall fail to pay an installment of interest on any of the Notes, which failure continues for 30 days after the date when due; or

indebtedness of the Company for borrowed money where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $5.0 million and such acceleration has not been rescinded or annulled or such
indebtedness repaid within a period of 30 days after receipt of a Notice of Default, provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason thereof would be deemed not to have occurred;
or 
 (7) a court or courts of competent jurisdiction shall render against the Company or any Significant
Subsidiary final judgments (not covered by insurance or a third party indemnity) for the payment of money in excess of $5.0 million in the aggregate, which final judgments are not paid, discharged or stayed for a period of 60 days; or


  
 -67-









 (8) the occurrence of any of the following: 

(A) except as permitted by the Intercreditor Agreement, this Indenture or such Security Document, any Security Document
ceases for any reason to be enforceable, provided that it will not be an Event of Default under this clause (8)(A) if the sole result of the failure of one or more Security Documents to be fully enforceable is that (i) any Lien
purported to be granted under such Security Documents on Collateral, individually or in the aggregate, having a Fair Market Value of not more than $1.0 million ceases to be an enforceable and perfected second priority Lien, subject only to
Priority Liens and Permitted Prior Liens, or (ii) any Lien purported to be granted under such Security Documents on Collateral, individually or in the aggregate, having a Fair Market Value in excess of $1.0 million ceases to be an
enforceable and perfected second priority Lien, subject only to Priority Liens and Permitted Prior Liens, and such defect is cured within 60 days after receipt of a Notice of Default; 

(B) except as permitted by the Intercreditor Agreement, this Indenture or such Security Document, any Lien purported to be
granted under any Security Document on Collateral, individually or in the aggregate, having a Fair Market Value in excess of $1.0 million ceases to be an enforceable and perfected second priority Lien, subject only to Priority Liens and
Permitted Prior Liens, and such defect is not cured within 60 days after receipt of a Notice of Default; or 

(C) the Company or any Guarantor, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any
obligation of the Company or any Guarantor set forth in or arising under any Security Document; 
 (9) except as
permitted by this Indenture, any Note Guaranty is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or
disaffirms its obligations under its Note Guaranty; 
 (10) the Company or any Significant Subsidiary pursuant to
or within the meaning of any Bankruptcy Law: 
 (A) commences as a debtor a voluntary case or proceeding;

substantially all of its property; 
 (D) makes a general assignment for the benefit of its creditors;

 (E) generally is not paying its debts as they become due; 

  
 -68-









 (F) files a petition in bankruptcy or answer or consent seeking
reorganization or relief; or 
 (G) consents to the filing of such a petition or the appointment of or taking
possession by a Receiver; or 
 (11) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that: 
 (A) grants relief against the Company or any Significant Subsidiary in an involuntary
case or proceeding or adjudicates the Company or any Significant Subsidiary insolvent or bankrupt; 
 (B)
appoints a Receiver of the Company or any Significant Subsidiary or for all or substantially all of the property of the Company or any Significant Subsidiary; or 

(C) orders the winding up or liquidation of the Company or any Significant Subsidiary; 

and in each case the order or decree remains unstayed and in effect for 60 consecutive days. 

The term “Bankruptcy Law” means Title 11 of the United States Code (or any successor thereto) or any similar federal,
state or foreign law for the relief of debtors. The term “Receiver” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. 

(b) No Event of Default under clause (4), (5), (6), (8)(A) or 8(B) of Section 6.01(a) shall occur until the Trustee
notifies the Company in writing, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not
cure the Default within the time specified in such clause after receipt of such notice. A notice given pursuant to this Section 6.01 shall be given by registered or certified mail, must specify the Default, demand that it be remedied and
state that the notice is a Notice of Default. When any Default under this Section 6.01 is cured, it ceases. 
 (c) The
Company will deliver to the Trustee promptly (and in any event within five Business Days) after any Officer becomes aware of the occurrence of a Default or Event of Default, written notice thereof. 

The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust
Officer with responsibility for this Indenture at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder or unless a Trust Officer with responsibility for this Indenture acquires actual
knowledge of such Event of Default in the course of performing other duties pursuant to this Indenture. 

  
 -69-









 Section 6.02 Acceleration. If an Event of Default (other than an Event of
Default specified in clause (10) or (11) of Section 6.01(a)) occurs and is continuing, the Trustee may, by written notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may,
by written notice to the Company and the Trustee, declare the principal amount of, and accrued and unpaid interest to the date of declaration on, all the Notes to be immediately due and payable. Upon such a declaration, such principal amount and
such accrued and unpaid interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(a)(10) or (11) occurs, the principal amount of, and accrued and unpaid interest to the date of such occurrence on, all
the Notes shall automatically become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holders of Notes. The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Notes which have become due solely by such declaration of
acceleration, have been cured or waived; (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any predecessor Trustee under Section 7.07
have been made. No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto. 

Section 6.03 Other Remedies. 
 (a) If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, subject to the terms of the Intercreditor Agreement, pursue any available remedy by proceeding at law
or in equity to collect payment of the principal amount and accrued and unpaid interest on the Notes or to enforce the performance of any provision of the Note Documents. 
 (b) The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any
right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent
permitted by applicable law. 
 Section 6.04 Waiver of Defaults and Events of Default. Subject to
Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except an uncured Default or Event of
Default in the payment of the principal of or any accrued but unpaid interest on any Note or any Default or Event of Default in respect of any provision of the Note Documents which, under Section 9.02, cannot be modified or amended without the
consent of the Holder of each Note affected. When a Default or Event of Default is waived, it is cured and ceases. 

Section 6.05 Control by Majority. The Holders of a majority in aggregate principal amount of the Notes then outstanding may
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 it. However, the Trustee may refuse to follow any direction that conflicts with law or this


  
 -70-









 
Indenture, the Security Documents or the Intercreditor Agreement, that the Trustee determines in good faith may be unduly prejudicial to the rights of another Holder or the Trustee, or that may
involve the Trustee in personal liability unless the Trustee is offered security or indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with
such direction. 
 Section 6.06 Limitations on Suits.

(a) A Holder may not pursue any remedy with respect to the Note Documents (except actions for payment of overdue principal or interest)
unless: 
 (1) the Holder gives to the Trustee written notice of a continuing Event of Default; 

(2) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the
Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to the Trustee reasonable security or indemnity
to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the request within
60 days after receipt of the request and the offer of security or indemnity; and 
 (5) no direction inconsistent
with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Notes then outstanding. 
 (b) No Holder of a Note shall have any right under any provision of the Note Documents to affect, disturb, or prejudice the rights of another Holder of a Note or to obtain a preference or priority over
another Holder of a Note. 
 Section 6.07 Rights of Holders to Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Holder of a Note to receive payment of the principal of and interest on the Notes held by such Holder, on or after the respective due dates expressed in the Notes and this Indenture (whether upon
redemption, repurchase, or otherwise) and to bring suit for the enforcement of any such payment on or after such respective due dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder,
provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in
the surrender, impairment, waiver or loss of the Lien of any of the Note Documents upon any property subject to such Lien. 

Section 6.08 Collection Suit by Trustee. If an Event of Default described in clause (1) or (2) of
Section 6.01(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Notes for the whole amount owing with respect to the Notes and such
further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

  
 -71-









 Section 6.09 Trustee May File Proofs of Claim. Subject to the terms of the
Intercreditor Agreement, the Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the Notes), its creditors or its property and shall be entitled and empowered to
collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any Receiver in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation, reasonable expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.07, and to the extent that such payment of the compensation, reasonable expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall
be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment
or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities.
 (a) If the Trustee collects any money or
property pursuant to this Article VI, it shall, subject to the terms of the Intercreditor Agreement, pay out the money or property in the following order: 
 (1) First, to the Trustee for amounts due under Section 7.07; 

(2) Second, to Holders for amounts due and unpaid on the Notes for the principal amount, and interest, as applicable,
ratably, without preference or priority of any kind, according to such respective amounts due and payable on the Holders’ Notes; 
 (3) Third, to such other Person or Persons, if any, to the extent entitled thereto; and 
 (4) Fourth, the balance, if any, to the Company. 
 (b) The Trustee may fix a
record date and payment date for any payment to Holders pursuant to this Section 6.10. 
 Section 6.11 Undertaking
for Costs. In any suit for the enforcement of any right or remedy under the Note Documents or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the 

  
 -72-









 
party litigant. This Section 6.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in aggregate principal
amount of the Notes then outstanding. This Section 6.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

Section 6.12 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such
proceedings, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding
has been instituted. 
 Section 6.13 Rights and Remedies Cumulative. No right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 6.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Subject to the terms of the Intercreditor Agreement, every right and remedy
given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

ARTICLE VII 

TRUSTEE 

Section 7.01 Obligations of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 
 (b) Except during
the continuance of an Event of Default: 
 (1) the Trustee need perform only those duties as are specifically set
forth in this Indenture and no others; and 
 (2) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, 

  
 -73-









 
upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee, however, shall examine any certificates and opinions which by any
provision hereof are specifically required to be delivered to the Trustee to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or other facts
stated therein. 
 This Section 7.01(b) shall be in lieu of Section 315(a) of the TIA and such Section 315(a) is
hereby expressly excluded from this Indenture, as permitted by the TIA. 
 (c) The Trustee may not be relieved from liability
for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 

(1) this paragraph does not limit the effect of Section 7.01(b); 

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved
that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable
with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05. 
 This Section 7.01(c) shall be in lieu of Sections 315(d)(1), 315(d)(2) and 315(d)(3) of the TIA and such Sections are hereby expressly excluded from this Indenture as permitted by the TIA.

 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers unless the Trustee shall have received adequate security or indemnity in its opinion against potential costs and liabilities incurred by it
relating thereto. 
 (e) Every provision of this Indenture that in any way relates to the Trustee is subject to
subsections (a), (b), (c) and (d) of this Section 7.01. 
 (f) The Trustee shall not be liable for interest
on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

Section 7.02 Rights of Trustee.
 (a) Subject to Section 7.01: 
 (1) The Trustee may rely
conclusively on any document reasonably believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

 (2) Before the Trustee acts or refrains from acting, it may require an

of Counsel. 
 (3) The Trustee may act through its agents and shall not be responsible for the misconduct or
negligence of any agent (other than an agent who is an employee of the Trustee) appointed with due care. 
 (4)
The Trustee shall not be liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers. 

(5) The Trustee may consult with counsel of its selection, and the advice or opinion of such counsel as to matters of law
shall be full and complete authorization and protection in respect of any such action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel; provided, however, that such
action taken, omitted or suffered by the Trustee does not constitute willful misconduct or negligence. 
 (6) The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security
or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. 
 (7) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation.

 (10) In no event
shall the Trustee, including in its capacity as Paying Agent, Registrar or Collateral Agent or in any other capacity hereunder, be liable under or in 

  
 -75-









 
connection with this Indenture for indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including but not limited to lost profits, whether or not
foreseeable, even if the Trustee has been advised of the possibility thereof and regardless of the form of action in which such damages are sought. 
 (11) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein. 

Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 7.10 and
7.11 and TIA Sections 310(b) and 311. 
 Section 7.04 Trustee’s Disclaimer. The Trustee makes no representation
as to the validity or adequacy of the Note Documents. It shall not be responsible for any statement in the Notes other than its certificate of authentication.

to each Holder of a Note notice of such Default or Event of Default (unless the same has been cured) within 90 days after it occurs or, if later, within 15 days after it becomes known to a Trust Officer of the Trustee. However, the Trustee may
withhold the notice if and for so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interests of Holders of Notes, except in the case of a Default in payment of the principal of or interest on any
Note when due. This Section 7.05 is in lieu of section 315(b) of the TIA and such provision is expressly excluded from this Indenture as permitted by the TIA.

 (a) If a report is
required by TIA Section 313, within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder of Notes a brief report dated as of such May 15 that complies
with TIA Section 313(a). If required by TIA Section 313, the Trustee also shall comply with TIA Sections 313(b)(1), (b)(2), (c) and (d). 
 (b) A copy of each report at the time of its mailing to Holders of Notes shall be mailed to the Company and, to the extent required by the TIA, filed with the SEC, and each stock exchange, if any, on
which the Notes are listed. The Company shall notify the Trustee in writing whenever the Notes become listed on any stock exchange or listed or admitted to trading on any quotation system and any changes in the stock exchanges or quotation systems
on which the Notes are listed or admitted to trading and of any delisting thereof. 
 Section 7.07 Compensation and
Indemnity. 
 (a) The Company shall pay to the Trustee from time to time such compensation (as agreed to from time to time by
the Company and the Trustee in writing) for its services (which compensation shall not be limited by any provision of law in regard to the 

  
 -76-









 
compensation of a trustee of an express trust). The Company shall reimburse the Trustee upon request for all reasonable disbursements, expenses and advances incurred or made by it. Such expenses
may include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 (b) The Company
and the Guarantors shall indemnify the Trustee or any predecessor Trustee (which for purposes of this Section 7.07 shall include its officers, directors, employees and agents) for, and hold it harmless against, any and all loss, liability or
expense including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred by it in connection with the acceptance or administration of its duties under this Indenture or any action or failure to act as
authorized or within the discretion or rights or powers conferred upon the Trustee hereunder including the reasonable costs and expenses of the Trustee and its counsel in defending (including reasonable legal fees and expenses) itself against any
claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee for which it may seek indemnity. The Company and the
Guarantors need not pay for any settlement effected without their prior written consent, which shall not be unreasonably withheld or delayed. 
 (c) The Company and the Guarantors need not reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by it resulting from its gross negligence, willful misconduct or
bad faith. 
 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the
Trustee shall have a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee. The obligations of the Company and the Guarantors under this Section 7.07 shall survive the satisfaction
and discharge of this Indenture or the resignation or removal of the Trustee. 
 (e) When the Trustee incurs expenses or renders
services after an Event of Default specified in clause (10) or (11) of Section 6.01(a) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The
provisions of this Section shall survive the termination of this Indenture. 
 Section 7.08 Replacement of
Trustee. 
 (a) The Trustee may resign by so notifying the Company. The Holders of a majority in aggregate principal amount
of the Notes then outstanding may remove the Trustee by so notifying the Trustee and the Company and may appoint a successor Trustee. 
 (b) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. The resignation or removal of a Trustee
shall not be effective until a successor Trustee shall have delivered the written acceptance of its appointment as described below. 
 (c) If a successor Trustee does not take office within 45 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the

of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (e) A successor Trustee
shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee and execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, subject to the rights set forth in Section 7.07, and be released from its obligations (exclusive of any liabilities that the retiring
Trustee may have incurred while acting as Trustee) hereunder, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A
successor Trustee shall mail notice of its succession to each Holder. 
 (f) A retiring Trustee shall not be liable for the acts
or omissions of any successor Trustee after its succession.

 Section 7.09 Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business (including the
administration of this Indenture) to, another corporation, the resulting, surviving or transferee corporation, without any further act, shall be the successor Trustee; provided such transferee corporation shall qualify and be eligible under
Section 7.10. Such successor Trustee shall promptly mail notice of its succession to the Company and each Holder. 

Section 7.10 Eligibility; Disqualification. 
 (a) The Trustee shall always satisfy the requirements of paragraphs (1), (2) and (5) of TIA Section 310(a). The Trustee (or its parent holding company) shall have a combined capital
and surplus of at least $100.0 million as set forth in its most recent published annual report of condition. If at any time the Trustee shall cease to satisfy any such requirements, it shall resign immediately in the manner and with the effect
specified in this Article VII. The Trustee shall be subject to the provisions of TIA Section 310(b). In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of such bank holding
company, shall meet the capital requirements of the TIA set forth in Section 310(a)(2). Nothing herein shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b).

 (b) If the Trustee has or acquires a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate
such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture.

ARTICLE VIII 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. The Company may at any time, at the option of the Board of Directors evidenced by a resolution set forth in an
Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII. 

Section 8.02 Legal Defeasance and Discharge. Upon the Company’s exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all
outstanding Notes (including the Note Guaranties) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to
have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guaranties), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under the Note Documents (and the Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of or interest on such Notes, when such payments are due, from the trust referred to in Section 8.04
hereof; 
 (2) the Company’s obligations with respect to such Notes under Article II and
Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company’s and the Guarantors’ obligations in connection therewith; and 
 (4) this
Article VIII. 
 Subject to compliance with this Article VIII, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 
 Section 8.03
Covenant Defeasance. Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.07 through 4.21 hereof (other than their obligations under clause (i) of Section 4.14 in respect of preservation of the


  
 -79-









 
corporate existence of the Company) and Article X hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied
(hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Note Guaranties, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not
constitute a Default or an Event of Default under Section 6.01(a) hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guaranties will be unaffected thereby. In addition, upon the Company’s
exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, clauses (3), (4) and (5) of Section 6.01(a) hereof
(in each case to the extent pertaining to a Default under any of Sections 4.07 through 4.21 hereof (other than a Default under clause (i) of Section 4.14 in respect of preservation of the corporate existence of the Company) or
Article X hereof) and clauses (6), (7), (8) and (9) of Section 6.01(a) hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant Defeasance. In order to exercise either Legal Defeasance under Section 8.02 or Covenant Defeasance under Section 8.03 hereof: 

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of and
interest on the outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular
Redemption Date; 
 (2) in the case of an election under Section 8.02 hereof, the Company must deliver to
the Trustee an Opinion of Counsel confirming that: 
 (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling; or 
 (B) since the date of this Indenture, there has been a
change in the applicable federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel
shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had not occurred; 

  
 -80-









 (3) in the case of an election under Section 8.03 hereof, the Company
must deliver to the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default shall have occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such
deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings); 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the
agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of the Guarantors is a party or by which the Company or any of the Guarantors is bound; 

(6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance
have been complied with. 
 The Collateral will be released from the Liens securing the Note Obligations, as provided in
Section 10.03, upon a Legal Defeasance or Covenant Defeasance in accordance with the provisions of this Section 8.04. 

The Trustee shall hold in trust the U.S. dollars and Governmental Securities deposited with it pursuant to this Section 8.04 and
shall apply all money held by the Trustee in trust to the payment of the principal of and interest on the Notes in accordance with this Indenture and the Notes. 
 Section 8.05 Repayment to Company. Subject to applicable abandonment property laws, any money held by the Trustee in trust for the payment of the principal of or interest on any Notes and
remaining unclaimed for two years after such principal or interest has become due and payable shall be paid to the Company on its request; and the Holder of such Notes will thereafter be permitted to look only to the Company for payment thereof, and
all liability of the Trustee with respect to such trust money will thereupon cease; provided, however, that the Trustee, before being required to make any such repayment, shall at the expense of the Company cause to be published once,
in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Company. 

  
 -81-









 Section 8.06 Reinstatement. If the Trustee is unable to apply any U.S. dollars
or non-callable Government Securities in accordance with this Article VIII by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and
the Guarantors’ obligations under the Note Documents will be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee is permitted to apply all such money in accordance with this
Article VIII; provided, however, that, if the Company makes any payment of principal of or interest on any Notes following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such
Notes to receive such payment from the money held by the Trustee. 
 ARTICLE IX 

AMENDMENTS; SUPPLEMENTS AND WAIVERS 
 Section 9.01 Without Consent of Holders. The Trustee or Collateral Agent (as the case may be) and the Company may amend or supplement any of the Note Documents, and the Collateral Agent and

(a) evidencing a successor to the Company or a Guarantor and the assumption by that successor of the Company’s or such
Guarantor’s obligations under the Note Documents;

benefit of the Holders or surrendering any right or power conferred upon the Company or any Guarantor;

 -82-

 (j)
releasing any Collateral from the Liens securing the Note Obligations pursuant to the terms of this Indenture, any of the Security Documents or the Intercreditor Agreement. 
 Section 9.02 With Consent of Holders. 
 (a) The Trustee or Collateral
Agent (as the case may be) and the Company may amend or supplement any of the Note Documents, and the Collateral Agent and other counterparties thereto may amend or supplement the Intercreditor Agreement, in each case with the written consent of the
Holders of at least a majority in aggregate principal amount of the Notes then outstanding. However, subject to Section 9.04, without the written consent of each Holder affected, an amendment, supplement or waiver may not: 

(1) alter the manner of calculation or rate of accrual of interest on any Note or change the time of payment of any
installment of interest on any Note; 
 (2) make any of the Notes payable in money or securities other than that
stated in the Notes; 
 (3) change the Stated Maturity of any Note or provide that any Note may be redeemed prior
to the Final Maturity Date at the option of the Company other than as described in Section 3.01(a) and (b); 

(4) reduce the principal amount or Redemption Price payable (as applicable) with respect to any of the Notes, or the
amount payable upon purchase pursuant to this Indenture or any Note;

(6) make any change in this Article IX; or 

(7) release any Guarantor from any of its obligations under its Note Guaranty or this Indenture, except in accordance with
the terms of this Indenture. 
 In addition, any amendment or supplement to the provisions of this Indenture or any Security
Document that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Note Obligations, except in accordance with the terms of this Indenture, any Security Document or the Intercreditor Agreement, will
require the consent of the Holders of at least 66-2/3% in aggregate principal amount of the Notes then outstanding. 

  
 -83-









 Without limiting the forgoing provisions of this Section 9.02(a), the Holders of a
majority in aggregate principal amount of the Notes then outstanding may, on behalf of all the Holders of the Notes, (i) waive compliance by the Company or any Guarantor with the restrictive provisions of the Note Documents, and (ii) waive
any past Default or Event of Default under this Indenture and its consequences, except an uncured failure to pay when due the principal amount of or accrued and unpaid interest on the Notes or the Redemption Price, or in respect of any provision
which under the Note Documents cannot be modified or amended without the consent of the Holder of each outstanding Note affected. 
 (b) It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if such
consent approves the substance thereof. 
 (c) After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall promptly mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amendment, supplement or waiver. 
 Section 9.03 Compliance with Trust Indenture
Act. Every amendment to or supplement of this Indenture or the Notes shall comply with the TIA as in effect at the date of such amendment or supplement. 
 Section 9.04 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to
its Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. After an amendment, supplement or waiver becomes effective, it shall bind every Holder of a Note.

 Section 9.05 Notation On or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note,
the Trustee may require the Holder of the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines,
the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. 

Section 9.06 Trustee to Sign Amendments, Etc. The Trustee or Collateral Agent (as the case may be) shall sign any amendment
or supplemental indenture authorized pursuant to this Article IX if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee or Collateral Agent. If it does, the Trustee or
Collateral Agent (as the case may be) may, in its sole discretion, but need not sign such amendment or supplemental indenture. In signing or refusing to sign such amendment or supplemental indenture, the Trustee or Collateral Agent (as the case may
be) shall be entitled to receive and, subject to Section 7.01, shall be fully protected in relying upon, an Officers’ 

  
 -84-









 
Certificate and Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplemental
indenture until the Board of Directors approves it. 
 Section 9.07 Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article IX, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore
or thereafter authenticated and delivered hereunder shall be bound thereby. 
 Section 9.08 Payment for Consent.
Neither the Company nor any of its Subsidiaries will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder of any Notes for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or amendment. 
 ARTICLE X

its rights thereunder in accordance therewith, subject to the terms and conditions thereof and of this Indenture and the Intercreditor Agreement. The Company will deliver to the Trustee copies of all documents delivered to the Collateral Agent (or
any co-collateral agent) pursuant to the Security Documents, and will do or cause to be done all such acts and things as may be required by the provisions of this Indenture 

  
 -85-









 
and the Security Documents to assure and confirm to the Collateral Agent (or any co-collateral agent) the security interest in the Collateral contemplated by this Indenture and the Security
Documents or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes. 
 (b) The Company will comply with the provisions of TIA §314. 

Section 10.02 Intercreditor Agreement. This Article X and the provisions of each Security Document are subject to the
terms, conditions and benefits set forth in the Intercreditor Agreement. Each Holder of the Notes, by its acceptance of the Notes (a) directs the Trustee and Collateral Agent to enter into the PNC Intercreditor Agreement and to perform their
obligations and exercise their rights thereunder in accordance therewith, subject to the terms and conditions of this Indenture, (b) further directs the Trustee and Collateral Agent, if any Indebtedness of the Company or any Guarantor under any
Credit Facility other than the Credit Agreement has been designated by the Company in an Officers’ Certificate delivered to the Trustee and Collateral Agent as “Priority Lien Debt” for purposes of this Indenture, to, at the request of
the Company, enter into an Additional Intercreditor Agreement with the agent or other representative of the holders of such Indebtedness designated pursuant to the terms of the documents governing such Credit Facility and to perform their
obligations and exercise their rights thereunder in accordance therewith, subject to the terms and conditions of this Indenture, (c) consents to the subordination of Liens provided for in any Intercreditor Agreement and (d) agrees that it
will be bound by, and will take no actions contrary to, the provisions of any Intercreditor Agreement. The foregoing provisions are intended as an inducement to the lenders under the Credit Agreement to extend credit to the Company and certain of
its Subsidiaries, and such lenders and each other present and future holder of Priority Lien Obligations are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement. 

Section 10.03 Release of Liens in Respect of Notes. 
 (a) The Collateral Agent’s (and any co-collateral agent’s) Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any other Note Obligations, and the right
of the Holders of the Notes and holders of such other Note Obligations to the benefits and proceeds of the Collateral Agent’s (and any co-collateral agent’s) Liens on the Collateral, and the obligations of the Company and each Guarantor or
other Restricted Subsidiary of the Company under the Security Documents, will automatically terminate and be discharged: 
 (1) upon satisfaction and discharge of this Indenture in accordance with Article XII hereof; 
 (2) upon a Legal Defeasance or Covenant Defeasance of the Notes in accordance with Article VIII hereof; 
 (3) upon payment in full and discharge of all Notes outstanding under this Indenture and all other Note Obligations that are outstanding and due and payable at the time the Notes are paid in full and
discharged; 

  
 -86-









 (4) in whole or in part, with the consent of the Holders of the requisite
percentage of Notes in accordance with Article IX hereof; and 
 (5) if and to the extent required by of the
Intercreditor Agreement. 
 (b) If any assets or rights of the Company, any Guarantor or any other Restricted Subsidiary of the
Company constituting a part of the Collateral are sold or otherwise disposed of to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, such assets or rights shall be
automatically released from the Liens securing the Note Obligations and the right of the Holders of the Notes and holders of the other Note Obligations to the benefits and proceeds of the Collateral Agent’s (or any co-collateral agent’s)
Liens on such assets or rights will automatically terminate and be discharged, provided that, subject to the terms of the Intercreditor Agreement, the Net Proceeds of such sale or disposition are applied in accordance with Section 4.10
hereof. 
 (c) If Equity Interests in any Guarantor or other Restricted Subsidiary of the Company are sold or otherwise disposed
of (including by way of consolidation or merger) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, the Liens on the assets and rights of such Guarantor or other
Restricted Subsidiary securing the Note Obligations will be automatically released and the rights of the Holders of the Notes and the holders of the other Note Obligations to the benefits and proceeds of the Collateral Agent’s (or any
co-collateral agent’s) Liens on such assets and rights, and the obligations of such Guarantor or other Restricted Subsidiary under the Security Documents, will automatically terminate and be discharged, provided that, subject to the
terms of the Intercreditor Agreement, the Net Proceeds of such sale or other disposition are applied in accordance with Section 4.10 hereof and, to the extent applicable, the Company complies with Article V hereof. 

(d) If all Priority Liens on any assets or rights of the Company, any Guarantor or any other Restricted Subsidiary of the Company
securing the Priority Lien Obligations are released (other than in connection with the payment in full of such Priority Lien Obligations and the termination or expiration of all commitments, if any, to extend credit that would constitute Priority
Lien Obligations), the Liens on such assets or rights securing the Note Obligations will also be automatically released and the right of the Holders of the Notes and holders of other Note Obligations to the benefits and proceeds of the Collateral
Agent’s (or any co-collateral agent’s) Liens on such assets or rights will automatically terminate and be discharged (provided that, if Priority Liens are at any time thereafter granted on such assets or rights to secure Priority
Lien Debt, the Company shall promptly take or cause the applicable Guarantor or other Restricted Subsidiary to take such actions as may be reasonably required to grant to the Collateral Agent (or a co-collateral agent) a second priority Lien
(subject to Priority Liens and Permitted Prior Liens) on such assets or rights to secure the Note Obligations). 
 (e) Upon
release of the Collateral, or any portion thereof, from the Liens securing the Notes and other Note Obligations, in each case in accordance with the provisions of this Section 10.03, all right, title and interest of the Collateral Agent (or any
co-collateral agent) therein shall thereupon cease and, at the written request of the Company and at the Company’s cost and expense, the Collateral Agent (or such co-collateral agent) (i) shall execute such


  
 -87-









 
instruments as the Company may reasonably request to evidence such release of record and (ii) if the Collateral so released is in the possession of the Collateral Agent (or such
co-collateral agent), shall deliver such Collateral to the Company. 
 (f) The release of any Collateral from the terms of this
Indenture will not be deemed to impair the security under this Indenture in contravention of provisions hereof if and to the extent the Collateral is released pursuant to the terms hereof. To the extent applicable, the Company will comply with TIA
§314(d) relating to the release of property or securities subject to the Lien of the Security Documents. Any certificate or opinion required by TIA §314(d) may be made by an Officer of the Company except in cases where TIA §314(d)
requires that such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert selected by the Company. Notwithstanding anything to the contrary in this paragraph, the Company will
not be required to comply with all or any portion of TIA §314(d) if it determines, in good faith based on advice of counsel, that under the terms of TIA §314(d) and/or any interpretation or guidance as to the meaning thereof of the SEC and
its staff, including “no action” letters or exemptive orders, all or any portion of TIA §314(d) is inapplicable to the released Collateral. 
 Section 10.04 Collateral Agent. 
 (a) The Collateral Agent (directly or
through co-collateral agents) will hold and, subject to the terms of the Intercreditor Agreement, will be entitled to enforce all Liens on the Collateral created by the Security Documents. 

(b) The Collateral Agent will not be obligated to do any of the following in the absence of the written direction of the Trustee or the
Holders of a majority in principal amount of the Notes then outstanding (as certified to by the Trustee): 
 (1)
to act upon directions purported to be delivered to it by any Person; 
 (2) to foreclose upon or otherwise
enforce any Lien; or 
 (3) to take any other action whatsoever with regard to any or all of the Security
Documents or the Liens created thereby or the Collateral. 
 (c) Subject to the terms of the Intercreditor Agreement and
Article VII, the Collateral Agent is authorized and empowered to institute and maintain such suits and proceedings as it may deem expedient to protect or enforce the Liens on the Collateral or the other rights under the Security Documents to
which the Collateral Agent is a party or to prevent any impairment of Collateral by any acts that may be unlawful or in violation of such Security Documents or this Indenture, and such suits and proceedings as the Collateral Agent may deem expedient
to preserve or protect its interests and the interests of the Holders in the Collateral, including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Liens or other rights under such Security Documents or hereunder or be prejudicial
to the interests of Holders or the Collateral Agent. 

  
 -88-









 (d) Notwithstanding any provision to the contrary contained elsewhere in this Indenture, the
Security Documents or the Intercreditor Agreement, the Collateral Agent shall not have any duties or responsibilities hereunder, nor shall the Collateral Agent have or be deemed to have any fiduciary relationship with the Trustee, any Holder or any
Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture, the Security Documents or the Intercreditor Agreement or otherwise exist against the Collateral Agent. Without
limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Except as expressly otherwise provided
in this Indenture, the Collateral Agent shall have and may use its sole discretion with respect to exercising or refraining from exercising any discretionary rights or taking or refraining from taking any actions which the Collateral Agent is
expressly entitled to take or assert under this Indenture, the Security Documents and the Intercreditor Agreement. 
 (e) The
Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by the Company or any Guarantor or is cared for, protected, or insured or has been encumbered, or that the
Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Company’s or any Guarantor’s
property constituting Collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency
thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent
pursuant to this Indenture, any Security Document or the Intercreditor Agreement, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent may act in any manner it may
deem appropriate, in its sole discretion given the Collateral Agent’s own interest in the Collateral and that the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder as to any of the foregoing.

 (f) No provision of this Indenture, the Intercreditor Agreement or any Security Document shall require the Collateral Agent
(or the Trustee) to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the
request or direction of Holders (or the Trustee in the case of the Collateral Agent) if it shall have reasonable grounds for believing that repayment of such funds is not assured to it. 

Section 10.05 Further Assurances. Subject to and to the extent consistent with the Intercreditor Agreement and the terms of
the Security Documents, upon the reasonable request of the Collateral Agent at any time and from time to time, the Company and each of the Guarantors shall promptly execute, acknowledge and deliver such documents and instruments, and take such other
actions, as shall be reasonably required by the Collateral Agent to create, perfect, protect, assure or enforce the Liens granted or intended to be granted by the Security Documents. 

  
 -89-









 Section 10.06 Insurance. 

(a) The Company and the Guarantors shall: 
 (1) keep their properties insured at all times by financially sound and reputable insurers; 
 (2) maintain such other insurance, to such extent and against such risks (and with such deductibles, retentions and exclusions), including fire and other risks insured against by extended coverage, as is
reasonably comparable to companies in the same or similar businesses operating in the same or similar locations, including public liability insurance against claims for personal injury or death or property damage occurring upon, in, about or in
connection with the use of any properties owned, occupied or controlled by them; and 
 (3) maintain such other
insurance as may be required by law. 
 (b) Upon the request of the Collateral Agent, the Company and the Guarantors will
furnish to the Collateral Agent information as to their property and liability insurance carriers. Holders of Notes, as a class, will be named as additional insureds on all material liability insurance policies of the Company and the Guarantors, and
the Collateral Agent (or a co-collateral agent, as applicable) will be named as second lender loss payee, with 30 days’ notice of cancellation or material change, on all property and casualty insurance policies of the Company and the
Guarantors. 
 Section 10.07 Impairment of Security Interest. The Company will not, and will not permit any of its
Restricted Subsidiaries to, take or knowingly or negligently omit to take any action, which action or omission would reasonably be expected to have the result of materially impairing the security interest with respect to the Collateral for the
benefit of the holders of the Note Obligations, except as expressly permitted by the Note Documents. 
 ARTICLE XI 

NOTE GUARANTIES 

Section 11.01 Guaranty. 
 (a) Subject to this Article XI, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, (i) that the principal of and interest on the Notes will be promptly paid in
full when due, whether at maturity, by acceleration, redemption or otherwise, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms
hereof and thereof, and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same shall be promptly paid in full when due or performed in accordance with the terms of the extension
or renewal, whether at stated maturity, by acceleration or otherwise. 

  
 -90-









 Failing payment when due of any amount so guaranteed or any performance so guaranteed for
whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that, except as otherwise provided in this Indenture, this Note Guaranty will
not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 (c) If any
Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by
either to the Trustee or such Holder, this Note Guaranty, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any Obligations guarantied hereby until payment in full of all Obligations
guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the Obligations guaranteed hereby may be accelerated as provided in
Article VI hereof for the purposes of this Note Guaranty, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (2) in the event of any declaration of
acceleration of such Obligations as provided in Article VI hereof, such Obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guaranty. The Guarantors will have the
right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guaranties. 
 (e) Each Note Guaranty shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company
become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be
effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Note
Guaranties, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof is rescinded, reduced, restored or
returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

  
 -91-









 (f) In case any provision of any Note Guaranty shall be invalid, illegal or unenforceable,
the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

(g) Each payment to be made by a Guarantor in respect of its Note Guaranty shall be made without set-off, counterclaim, reduction or
diminution of any kind or nature. 
 (h) Each Guarantor acknowledges that it will receive direct and indirect benefits from the
financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Note Guaranty are knowingly made in contemplation of such benefits. 

Section 11.02 Limitation on Guarantor Liability. Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms
that it is the intention of all such parties that the Note Guaranty of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or
any similar federal or state law to the extent applicable to any Note Guaranty. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the
maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution
from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article XI, result in the obligations of such Guarantor under its Note Guaranty not constituting a fraudulent transfer
or conveyance. 
 Section 11.03 Execution and Delivery of Note Guaranty. 

To evidence its Note Guaranty set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guaranty
substantially in the form attached as Exhibit B hereto will be endorsed by such Guarantor on each Note authenticated and delivered by the Trustee. 
 Each Guarantor hereby agrees that its Note Guaranty set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note
Guaranty. 
 If an officer of a Guarantor whose signature is on this Indenture or on any notation of the Note Guaranty no longer
holds that office at the time the Trustee authenticates the Note on which a notation of the Note Guaranty is endorsed, the Note Guaranty will be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the notation of Note Guaranty endorsed on such Note on behalf of the Guarantors.


  
 -92-









 Section 11.04 Guarantors May Consolidate, etc., on Certain Terms. 

(a) Except for a Guarantor whose obligations under its Note Guaranty are to be released as provided in Section 11.05(a) hereof, no
Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless: 

(1) the Person (if other than such Guarantor) formed by or surviving any such consolidation or merger expressly assumes
all the obligations of that Guarantor under (i) its Note Guaranty pursuant to a supplemental indenture, executed and delivered to the Trustee, and (ii) to the extent applicable, the Security Documents pursuant to supplements thereto,
executed and delivered to the Collateral Agent; 
 (2) after giving effect to such transaction, no Default or
Event of Default exists; and 
 (3) the Company shall have, at or prior to the date of such consolidation or
merger, delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation or merger complies with this Section 11.04 and, if a supplemental indenture and/or supplements to Security Documents
are required in connection with such transaction, such supplemental indenture and/or supplements comply with this Section 11.04, and that all conditions precedent herein provided for relating to such transaction have been complied with.

 The foregoing clause (2) shall not apply to any merger or consolidation of a Guarantor with or into any Subsidiary of the Company that
is not a Guarantor. 
 (b) Upon any consolidation of a Guarantor with, or merger of a Guarantor into, any other Person in
accordance with Section 11.04(a), the successor Person formed by such consolidation or into which such Guarantor is merged shall succeed to, and be substituted for, and may exercise every right and power of, such Guarantor under the Note
Documents with the same effect as if it had been named as a Guarantor therein. Such successor Person thereupon may cause to be signed any or all of the Note Guaranties to be endorsed upon all of the Notes issuable hereunder which theretofore shall
not have been signed by the Company and delivered to the Trustee. All the Note Guaranties so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guaranties theretofore and thereafter issued in accordance
with the terms of this Indenture as though all of such Note Guaranties had been issued at the date of the execution hereof. 

Section 11.05 Releases. 
 (a) In the event the Equity Interests of any Guarantor is sold or otherwise disposed of (including by way of consolidation or merger) to a Person that is not (either before or after giving effect to such
transaction) the Company or a Restricted Subsidiary of the Company, then such Guarantor will be automatically released and relieved of any obligations under its Note Guaranty, provided that, subject to the terms of the Intercreditor
Agreement, the Net Proceeds of such sale or other disposition are applied in accordance with Section 4.10 hereof and, to the extent applicable, the Company complies with Article V hereof. 

  
 -93-









 (b) Upon designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted
Subsidiary in accordance with the terms of this Indenture, such Guarantor will be automatically released and relieved of any obligations under its Note Guaranty. 
 (c) Upon Legal Defeasance or Covenant Defeasance in accordance with Article VIII hereof or satisfaction and discharge of this Indenture in accordance with Article XII hereof, each Guarantor will
be automatically released and relieved of any obligations under its Note Guaranty. 
 Any Guarantor not released from its
obligations under its Note Guaranty as provided in this Section 11.05 will remain liable for the full amount of principal of and interest on the Notes and for the other obligations of such Guarantor under this Indenture as provided in this
Article XI. 
 ARTICLE XII 
 SATISFACTION AND DISCHARGE OF INDENTURE 
 Section 12.01 Satisfaction and
Discharge of Indenture. This Indenture shall cease to be of further force and effect, and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture,
when either: 
 (A) all Notes theretofore authenticated and delivered (other than (i) Notes which have been
destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07 and (ii) Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company as provided in
Section 12.03) have been delivered to the Trustee for cancellation; or 
 (B) all Notes not theretofore
delivered to the Trustee for cancellation, 
 (i) have become due and payable, 

(ii) will become due and payable at the Final Maturity Date within one year, or 

(iii) are to be called for redemption within one year under arrangements reasonably satisfactory to the Trustee for the
giving of notice of redemption by the Trustee in the name, and at the expense, of the Company; 
 provided, in the case of
clause (B), that 
 (1) the Company or any Guarantor has deposited with the Trustee or a Paying Agent (other
than the Company or any of its Affiliates) as trust funds in trust for the purpose of and in an amount sufficient to pay and discharge in respect of all Notes not theretofore delivered to the Trustee for cancellation, the principal thereof and
interest thereon to the date of such deposit (in the case of Notes which have become due and 

  
 -94-









 
payable) or to the Final Maturity Date or Redemption Date, as the case may be. In the event that the Company exercises its right to redeem the Notes as provided in Article III, the Company
shall have the right to withdraw its funds previously deposited with the Trustee or Paying Agent pursuant to the immediately preceding sentence; 
 (2) the Company or any Guarantor has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein relating to the satisfaction and discharge of this
Indenture have been complied with. 
 The Collateral will be released from the Lien securing the Note Obligations as provided in
Section 10.03 upon a satisfaction and discharge in accordance with the provisions of this Section 12.01. 

Section 12.02 Application of Trust Money. Subject to the provisions of Section 12.03, the Trustee or a Paying Agent
shall hold in trust, for the benefit of the Holders, all money deposited with it pursuant to Section 12.01 and shall apply the deposited money in accordance with this Indenture and the Notes to the payment of the principal of and interest on
the Notes. 
 Section 12.03 Repayment to Company. 

(a) The Trustee and each Paying Agent shall promptly pay to the Company upon request any excess money (1) deposited with them
pursuant to Section 12.01 and (2) held by them at any time. 
 (b) The Trustee and each Paying Agent shall, subject to
applicable abandonment property laws, pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years after a right to such money has matured; provided, however, that
the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the Company cause to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified
therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another person. 
 Section 12.04
Reinstatement. 
 (a) If the Trustee or any Paying Agent is unable to apply any money in accordance with
Section 12.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’
obligations under this Indenture, the Notes and the other Note Documents shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 until such time as the Trustee or such Paying Agent is permitted to apply all
such money in accordance with Section 12.02; provided, however, that if the Company has made any payment of the principal of or interest on any Notes because of the 

  
 -95-









 
reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive any such payment from the money held by the Trustee or such Paying Agent.

 (b) If pursuant to the last sentence of Section 12.01(a)(1), the Company withdraws its previously deposited funds as a
result of its exercise of its redemption right, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit has occurred pursuant to Section 12.01.

Payment of the principal of and interest on this Note shall be made at the office or agency of the Company maintained for that purpose at the Corporate Trust Office of the Trustee in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made through the Paying Agent by check mailed to the address of the Person
entitled thereto as such address appears in the Registrar; provided further that a Holder of Notes in an aggregate principal amount in excess of $2.0 million will be paid interest on such Notes by wire transfer in immediately available

	4.	INDENTURE, LIMITATIONS 

 This
Note is one of a duly authorized issue of Notes of the Company designated as its 8.50% Senior Secured Second Lien Notes Due 2017 (the “Notes”), issued under an Indenture dated as of
            , 2012 (together with any supplemental indentures thereto, the “Indenture”), between the Company and the Trustee. The terms of this Note include those stated in the
Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Note is subject to all such terms, and the Holder of this Note is referred to
the Indenture and said Act for a statement of them. Capitalized terms used in this Note shall have the meanings assigned to them in the Indenture unless otherwise indicated. 
 The Notes and other Note Obligations are secured on a second priority basis (subject to Priority Liens and Permitted Prior Liens) by Liens on substantially all of the assets (other than Excluded Assets)
of the Company, subject to the terms of the Indenture, the Security Documents and the Intercreditor Agreement.

Note Obligations will be secured on a second priority basis (subject to Priority Liens and Permitted Prior Liens) by Liens on substantially all of the assets (other than Excluded Assets) of such Domestic Subsidiary, subject to the terms of the
Indenture, the Security Documents and the Intercreditor Agreement. 
 If, after the date of the Indenture, any Restricted
Subsidiary that is not a Guarantor guarantees or provides credit support for (other than by granting Liens on its assets) any Priority Lien Obligations, the Notes will be guaranteed by such Restricted Subsidiary, subject to the terms of the
Indenture. 
 If, after the date of the Indenture, the Priority Lien Debt is secured by Liens on any assets of the Company or
its Restricted Subsidiaries not theretofore subject to a Priority Lien (other than Rule 3-16 Excluded Assets, but including any other Excluded Assets), the Notes and other Note Obligations will be secured on a second priority basis (subject to
Priority Liens and Permitted Prior Liens) by Liens on such assets, subject to the terms of the Indenture, the Security Documents and the Intercreditor Agreement. 
  

	5.	REDEMPTION AT THE OPTION OF THE COMPANY 

 The Company may at any time on any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal
amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest on the principal amount of the Notes redeemed to, the Redemption Date. 
 “Applicable Premium” means, with respect to any Note on any Redemption Date, the excess of: (a) the present value at such Redemption Date of (i) the principal amount of the Note
redeemed plus (ii) all required interest payments due on such principal amount from such 

  
 A-5









 
Redemption Date through January 15, 2017 (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 redeemed. 
 Unless the Company defaults in the payment of
the Redemption Price, interest will cease to accrue on the Notes or portions thereof call for redemption on the applicable Redemption Date. 
  

	6.	NOTICE OF REDEMPTION 

 Notice of
redemption, as set forth in Section 3.03 of the Indenture, will be mailed by first-class mail at least 30 days but not more than 60 days before a Redemption Date to each Holder of Notes to be redeemed at its registered address. Notes in
denominations larger than $2,000 may be redeemed in part, but only in whole multiples of $1,000 in excess thereof. On and after the Redemption Date, subject to the deposit with the Paying Agent of funds sufficient to pay the Redemption Price, such
Notes or portions of them called for redemption will cease to be outstanding, whether or not the Note is delivered to the Paying Agent, and the rights of the Holder in respect thereof shall cease (other than the right to receive the Redemption
Price). 
  

	7.	CHANGE IN CONTROL AND SALE OF ASSETS 

 Upon the occurrence of (a) a Change in Control, each Holder shall have the right to require the Company to repurchase all or part of such Holder’s Notes at a purchase price in cash equal to 101%
of the principal amount of the Notes repurchased plus accrued and unpaid interest on such principal amount to the date of purchase, and (b) an Asset Sale, the Company may be obligated to make an offer to purchase the Notes from the Holders with
Excess Proceeds of such Asset Sale at a purchase price equal to 100% of the principal amount of such Notes plus accrued interest on such principal amount to the date of purchase; all as provided in, and subject to the terms of, the Indenture.

  

	8.	DENOMINATIONS, TRANSFER, EXCHANGE 


The Notes are in registered form, without coupons, in denominations of $2,000 principal amount and integral multiples of $1,000 principal
amount in excess thereof. A Holder may register the transfer of or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any
taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 
  

	9.	PERSONS DEEMED OWNERS 

 The
Holder of a Note may be treated as the owner of it for all purposes. 
  

	10.	UNCLAIMED MONEY 

 Subject to
applicable abandonment property laws, if money for the payment of principal or interest remains unclaimed for two years, the Trustee and any Paying Agent will pay the 

  
 A-6









 
money back to the Company at its written request, subject to applicable unclaimed property law and the provisions of the Indenture. After that, Holders entitled to money must look to the Company
for payment as general creditors unless an applicable abandoned property law designates another person. 
  

	11.	AMENDMENT, SUPPLEMENT AND WAIVER 


Subject to certain exceptions, the Note Documents and the Intercreditor Agreement may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and an existing Default or Event of Default and its consequence or compliance with any provision of the Note Documents and the Intercreditor Agreement may be
waived in a particular instance with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without the consent of or notice to any Holder, the Company and other counterparties thereto may amend or
supplement the Note Documents and the Intercreditor Agreement to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of the Holders in any material respect. 

 

	12.	SUCCESSOR ENTITY 

 When a
successor entity assumes all the obligations of its predecessor under the Note Documents in accordance with the terms and conditions of the Indenture, the predecessor entity shall be released from those obligations. 

 

	13.	DEFAULTS AND REMEDIES 

 Events of
Default are set forth in the Indenture. If an Event of Default (other than an Event of Default resulting from certain events of bankruptcy or insolvency as described below) occurs and is continuing, the Trustee may, by notice to the Company, or the
Holders of at least 25% in aggregate principal amount of the Notes then outstanding may, by notice to the Company and the Trustee, declare the principal amount of, and accrued and unpaid interest to the date of declaration on, all the Notes to be
immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest shall be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default and shall result in the Notes
being immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Notes. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may rescind an
acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Notes which have become due solely by such declaration of acceleration, have been cured or waived; (b) the
rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any predecessor Trustee under the Indenture have been made. No such rescission shall affect any
subsequent Event of Default or impair any right consequent thereto. Holders may not enforce the Note Documents except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Note Documents. Subject
to certain limitations, Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default or Event
of Default 

  
 A-7









 
(except a Default in payment of principal or interest) if and so long as it determines that withholding notice is in their interests. The Company is required to file periodic certificates with
the Trustee as to the Company’s compliance with the Indenture and knowledge or status of any Default or Event of Default. 
  

	14.	TRUSTEE DEALINGS WITH THE COMPANY 


Wells Fargo Bank, National Association, the initial Trustee under the Indenture, in its individual or any other capacity, may make loans
to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 

 

	15.	NO RECOURSE AGAINST OTHERS 

 A
director, officer, employee or shareholder, as such, of the Company or any Guarantor shall not have any liability for any obligations of the Company or the Guarantors under any Note Documents nor for any claim based on, in respect of or by reason of
such obligations or their creation. The Holder of this Note by accepting this Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Note. 

 

	16.	AUTHENTICATION

not be valid until the Trustee or an authenticating agent manually signs the certificate of authentication on the other side of this Note.
