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. 
 (c) Each Global Note shall represent such of the outstanding 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, or transfers of such Notes. 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 the 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. 

  
 -28-









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

  
 -29-









 (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 amount of Notes to be authenticated, 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. 
 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 

  
 -30-









 
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. 
 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 and, if applicable, a transfer certificate each 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. 

  
 -31-









 (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. 
 (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. 

  
 -32-









 (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 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 

  
 -33-









 
Note that is issued in exchange for a Global Note but is not itself a Global Note. 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 a certificate 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 certificate. As used in this Section 2.12(b), the term “transfer” encompasses any sale, pledge, transfer,
hypothecation or other disposition of any Note. 
 (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 

  
 -34-









 
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. 

(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. 

  
 -35-









 Section 2.13 CUSIP Numbers. The Company in issuing the Notes may use a
“CUSIP” number (if then generally in use), and, if so, the Trustee shall use the “CUSIP” number 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 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. The Company will promptly notify the Trustee in writing of any change in the “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. 
 (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. 

  
 -36-









 (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; 
 (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 have been issued 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) 

  
 -37-









 
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. 

(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. 

  
 -38-









 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
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

 (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; 
 (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

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

(a) The Company shall promptly make all payments in respect of the Notes on the dates and in the manner provided in the Notes and this
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

(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 transfer instructions to the Trustee at least 10 Business

the extent lawful, and shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

 Section 4.02 Maintenance of Office or Agency. The Company will maintain an office or agency of the Trustee, Registrar

shall fail 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.

 (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

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 

  
 -43-









 
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.

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 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; 

  
 -51-









 (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 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. 

  
 52 









 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;

 (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. 

  
 -53-









 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. 
 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 

  
 -54-









 
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 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 

  
 -55-









 
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. 
 (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; 

  
 -56-









 (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; 
 (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. 

  
 -57-









 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. 
 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 

  
 -58-









 
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. 
 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. 

  
 -59-









 (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. 
 (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 

  
 -60-









 
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 Notes and Warrants upon exercise of the subscription rights distributed pursuant to the Rights Offering, the Company shall, with respect


  
 -61-









 
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 
 (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.

obligation of the Company or any Guarantor set forth in or arising under any Security Document; 

  
 -65-

 -66-









 (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. 

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.


  
 -67-









 (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 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. 

  
 -68-









 (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. 

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.

(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 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. 

  
 -70-









 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

 (1) the
Trustee need perform only those duties as are specifically set forth in this Indenture and no others; and

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, 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.

made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

 (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

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

(9) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its
right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including, without limitation as Paying Agent, Registrar and Collateral Agent, and to each agent, custodian and other Person

Registrar or Collateral Agent or in any other capacity hereunder, be liable under or in 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.

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.

known to a 

  
 -73-









 
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.

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 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

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

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

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 

  
 -76-









 
(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 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 

  
 -77-









 
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; 
 (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; 

  
 -78-









 (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. 
 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

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; 

  
 -80-









 (2) make any of the Notes payable in money or securities other than that

(4) reduce the principal amount or Redemption Price payable (as applicable) with respect to any of the Notes, or the

(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.

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. 
 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

(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.


  
 -81-









 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’ 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 
 COLLATERAL AND SECURITY 
 Section 10.01 Security Interest. 

(a) The due and punctual payment of the principal of and interest on the Notes when and as the same shall be due and payable, whether on
an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest (to the extent permitted by law) on the Notes and performance of all other Obligations of the Company
and the Guarantors to the Holders of Notes or the Trustee under this Indenture and the Notes, including, without limitation, the Note Guaranties, according to the terms hereunder or thereunder (collectively the “Note Obligations”) are
secured as provided in the Security Documents. Each Holder of Notes, by its acceptance thereof, consents and agrees to the terms of the Security Documents (including, without limitation, the provisions providing for foreclosure and release of
Collateral) as the same may be in effect or may be amended from time to time in accordance with their terms and the terms of this Indenture. Wells Fargo Bank, N.A. shall initially act as Collateral Agent and shall be authorized to appoint
co-collateral agents as necessary in its sole discretion. Pursuant to such authority, the Collateral Agent hereby appoints PNC Bank, National Association, as co-collateral agent to act as mortgagee for the benefit of the holders of the Note
Obligations and the Priority Lien Obligations under any mortgages on real property located in the State of Minnesota that are granted by the Company pursuant to Section 4.18(c) hereof. Each Holder of Notes, by its acceptance of Notes, and the
Trustee direct the Collateral Agent (directly or through co-collateral agents) to enter into the Security Documents and to perform its obligations and exercise 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 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 

  
 -83-









 
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; 
 (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


  
 -84-









 
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 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. 
 (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. 

  
 -86-









 (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. 

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. 

  
 -87-









 (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. 
 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. 

  
 -88-









 (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. 
 (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. 

  
 -89-









 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. 
 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 

  
 -90-









 (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. 

(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 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. 

  
 -92-









 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 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.

            , 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

 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.

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.

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.
