and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
 (c) Euroclear and
Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream

Section 2.02 Execution and Authentication. 

At least one Officer must sign the Notes for the Company by manual or facsimile signature. 

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be
valid. 
 A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence
that the Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a written order of the Company signed by at
least one Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes; provided that the Trustee shall be entitled to receive an
Officer’s Certificate and an Opinion of Counsel of the Company addressing such matters as the Trustee may reasonably request. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes
authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof. 
 The
Trustee may appoint an authenticating agent 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 has the same rights as an Agent to deal with Holders or an Affiliate of the Company. 

Section 2.03 Registrar and Paying Agent. 

The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries or Parent may act as Paying Agent or Registrar. 

  
 27 

 The Company initially appoints The Depository Trust Company (“DTC”) to act as
Depositary with respect to the Global Notes. 
 The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to
act as Custodian with respect to the Global Notes. The Company has entered into a letter of representations with DTC in the form provided by DTC and the Trustee and each Agent are hereby authorized to act in accordance with such letter and
Applicable Procedures. Neither the Trustee nor any Agent shall have responsibility for any actions taken or not taken by DTC. 
 Section 2.04 Paying
Agent to Hold Money in Trust. 
 The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying
Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or Special Interest, if any, or interest on the Notes, and will notify the Trustee of any default by
the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the
Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary or Parent) will have no further liability for the money. If the Company or a Subsidiary or Parent acts as Paying Agent, it will segregate and hold
in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company or Parent, the Trustee will serve as Paying Agent for the Notes. 

Section 2.05 Holder Lists. 
 The
Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the
Company will furnish to the Trustee at least seven 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 the Holders of Notes and the Company shall otherwise comply with TIA § 312(a). 
 Section 2.06 Transfer and
Exchange. 
 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary
to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes
will be exchanged by the Company for Definitive Notes if: 
 (1) the Company delivers to the Trustee notice from the
Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 120 days after
the date of such notice from the Depositary; 
 (2) the Company in its sole discretion determines that the Global Notes (in

for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged
for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof. In connection with any proposed transfer of a

 (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and
canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on the Schedule of Exchanges of Interests on such Global
Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on the Schedule of Exchanges of Interests on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect
such increase. 

  
 38 

 (i) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes
and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note
for any registration of transfer or exchange, but the Company may require a Holder to pay a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof). 

(3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or
in part, except the unredeemed portion of any Note being redeemed in part. 
 (4) All Global Notes and Definitive Notes
issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or
Definitive Notes surrendered upon such registration of transfer or exchange. 
 (5) Neither the Registrar nor the Company
will be required: 
 (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the
opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part; or 
 (C) to register the transfer of or to exchange a Note between a record date
and the next succeeding interest payment date. 
 (6) Prior to due presentment for the registration of a transfer of any
Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other
purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. 
 (7) The Trustee
will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 
 (8) All
certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 

(9) Neither the Trustee nor the Registrar shall have any duty to monitor the Company’s compliance with or have any
responsibility with respect to the Company’s compliance with any federal or state securities laws in connection with registrations of transfers and exchanges of the Notes. The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable 

  
 39 

 
law with respect to any transfer of any interest in any Notes (including any transfers between or among the Depositary’s participants or beneficial owners of interests in any Global Note)
other than to require delivery of such certificates and other documentation, as is expressly required by, and to do so if and when expressly required by, the terms of this Indenture and to examine the same to determine substantial compliance as to
form with the express requirements hereof. 
 (10) To the extent not provided pursuant to Section 2.06(a), the transferor
shall provide or cause to be provided to the Trustee all information reasonably necessary to allow the Trustee to comply with any applicable tax reporting obligations, including, without limitation, any cost basis reporting obligations under Code
section 6045. 
 Section 2.07 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee or the Company or if a Holder claims that a Note has been damaged, lost or wrongfully taken
and the Trustee and the Company receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the
requirements of the Trustee and the Company are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the
Guarantors, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 

Every replacement Note is an additional obligation of the Company and the Guarantors and will be entitled to all of the benefits of this
Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 2.08 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company, a Subsidiary of the Company or Parent shall not be deemed to be outstanding for purposes of Section 3.07(a)
hereof. 
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a
Subsidiary, Parent or an Affiliate of any thereof) holds, on a Redemption Date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to
accrue interest. 
 Section 2.09 Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by
the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the 

  
 40 

 
Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver
or consent, only Notes that the Trustee knows are so owned will be so disregarded. 
 Section 2.10 Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order,
will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without
unreasonable delay, the Company will prepare and the Trustee will authenticate Definitive Notes in exchange for temporary Notes. 
 Holders
of temporary Notes will be entitled to all of the benefits of this Indenture. 
 Section 2.11 Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and cancelled Notes will be retained
and disposed of by the Trustee in accordance with its customary procedures and applicable law (subject to the record retention requirement of the Exchange Act). Certification of the cancellation of all canceled Notes will be delivered to the Company
upon request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 

Section 2.12 Defaulted Interest. 
 If
the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record
date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The
Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before
the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed or sent to Holders a notice that states the special record date, the
related payment date and the amount of such interest to be paid. 
 Section 2.13 CUSIP Numbers. 

The Company in issuing the Notes may use CUSIP, ISIN or other similar numbers, if then generally in use, and the Trustee may use such numbers
in any notice (including any notice of redemption or exchange), which may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice (including any notice of redemption or
exchange) and that reliance may be placed only on the other identification numbers printed on the Notes, and any such notice or notice of redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify
the Trustee in writing of any change in the CUSIP, ISIN or other similar numbers.

 ARTICLE 3 

REDEMPTION AND PREPAYMENT 
 Section 3.01
Notices to Trustee. 
 If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07
hereof, it must furnish to the Trustee, at least 30 days but not more than 60 days before a Redemption Date (unless a shorter period shall be satisfactory to the Trustee), an Officer’s Certificate setting forth: 

(1) the clause of this Indenture pursuant to which the redemption shall occur; 

(2) the Redemption Date; 

(3) the principal amount of Notes to be redeemed; and 

(4) the redemption price (or manner of calculation if not then known). 

If the Company elects to redeem less than all Notes Outstanding pursuant to the optional redemption provisions of Section 3.07, it shall
furnish the above information to the Trustee at least 15 days prior to the date notice is to be given to Holders of such redemption (unless a shorter period shall be satisfactory to the Trustee). If the redemption price is not known at the time such
notice is to be given, the actual redemption price, calculated as described in the terms of the Notes, will be set forth in an Officer’s Certificate of the Company delivered to the Trustee no later than two Business Days prior to the Redemption
Date. 
 Section 3.02 Selection of Notes to Be Redeemed or Purchased. 

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption in accordance with DTC’s
procedures except: 
 (1) if the Notes are listed on any national securities exchange, in compliance with the requirements of
the principal national securities exchange on which the Notes are listed; or 
 (2) if otherwise required by law or to comply
with the rules of the Depositary. 
 In the event of partial redemption by lot, the particular Notes to be redeemed will be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. 

The Trustee will promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. No Notes of $2,000 or less can be redeemed in part, and the unredeemed portion of the Notes of any Holder must be equal to $2,000 in principal amount or integral multiples of $1,000 in excess
thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. 

The provisions in this Section 3.02 and Sections 3.03 and 3.04 hereof relating to a redemption of the Notes will also be applicable to a
repurchase of the Notes pursuant to an Asset Sale Offer or a Change of Control Offer, except as otherwise provided in this Indenture. 

  
 42 

 Section 3.03 Notice of Redemption. 

Notices of redemption will be delivered at least 30 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed
at its registered address or otherwise delivered in accordance with the procedures of DTC, except that redemption notices may be delivered more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the
Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12. Notes called for redemption become due on the Redemption Date, provided that notices of redemption may be conditioned on one or more conditions precedent, such as
the closing of a Change of Control or a financing transaction. The Company will provide prompt written notice to the Trustee rescinding such redemption not less than two Business Days prior to the redemption date (unless a shorter period shall be
satisfactory to the Trustee) in the event that any such condition precedent shall not have occurred or at any time in the Company’s discretion if in the good faith and judgment of the Company any or all of such conditions will not be satisfied,
and thereafter such redemption and notice of redemption shall be rescinded and of no force or effect. Upon receipt of such notice from the Company rescinding such redemption, the Trustee will promptly send a copy of such notice to the Holders of the
Notes to be redeemed in the same manner in which the notice of redemption was given. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such
redemption may be performed by another Person. 
 The notice will identify the Notes to be redeemed and will state: 

(1) the Redemption Date; 

(2) the redemption price (or manner of calculation if not then known); 

(3) 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 surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note or, if the Note is a Global Note, an adjustment will be made to the schedule
attached thereto; 
 (4) the name and address of the Paying Agent; 

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(6) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to
accrue on and after the Redemption Date; 
 (7) the paragraph of the Notes and/or Section of this Indenture pursuant to which
the Notes called for redemption are being redeemed; 
 (8) any conditions precedent to such redemption; and 

(9) that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or similar number, if any, listed in
such notice or printed on the Notes. 
 At the Company’s request, the Trustee will give the notice of redemption in the Company’s
name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the Redemption Date (or such shorter time as may be acceptable to the Trustee), an Officer’s Certificate
requesting that the Trustee give such notice together with the notice to be given setting forth the information to be stated in such notice as provided in the preceding paragraph. 

  
 43 

 Provisions of this Indenture that apply to Notes called for redemption or purchase also apply to
portions of Notes called for redemption or purchase. On and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption. 

Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed or sent in accordance with Section 3.03 hereof, and any conditions precedent stated in such notice
have been satisfied, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. 
 Section 3.05
Deposit of Redemption or Purchase Price. 
 One Business Day prior to the redemption or purchase date, the Company will deposit with
the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest and Special Interest, if any, on all Notes to be redeemed or purchased on that date, subject to any conditions precedent stated in
such notice being satisfied. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of,
and accrued interest and Special Interest, if any, on, all Notes to be redeemed or purchased. 
 If the Company complies with the provisions
of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date
but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase
is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid,
and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

Section 3.06 Notes Redeemed or Purchased in Part. 

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the
Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered, or if the Note is a Global Note, an adjustment will be made to the Schedule
of Exchange of Interests on such Global Note. 
 Section 3.07 Optional Redemption.

(2) the redemption occurs within 90 days of the date of the closing of such sale of Equity Interests. 

(b) Prior to April 15, 2022, the Company on any one or more occasions may 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 and Special Interest, if any, to, the date of redemption (the
“Redemption Date”). 
 (c) Except pursuant to Sections 3.07(a) and 3.07(b) hereof, the Notes will not be redeemable at the
Company’s option prior to April 15, 2022. 
 (d) On or after April 15, 2022, the Company on any one or more occasions may
redeem, all or a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Special Interest, if any, on

	 2024
	  	 	101.104	% 
	 2025 and thereafter
	  	 	100.000	% 

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes
or portions thereof called for redemption on the applicable Redemption Date. 
 (e) This Indenture will not prohibit the Company and its
Restricted Subsidiaries from purchasing Notes in the open market or otherwise at any time or from time to time. 
 (f) Any redemption
pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. 
 Section 3.08 Mandatory
Redemption. 
 The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 

Section 3.09 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
and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer
will remain open 

  
 45 

 
for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the
“Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of
Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes
so purchased will be made in the same manner as interest payments are made. 
 If the Purchase Date is on or after an interest record date
and on or before the related interest payment date, any accrued and unpaid interest and Special Interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest
will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Company
will deliver a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which
will govern the terms of the Asset Sale Offer, will state: 
 (1) that the Asset Sale Offer is being made pursuant to this
Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer
Amount, the purchase price and the Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to
accrue interest; 
 (4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to
the Asset Sale Offer will cease to accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note
purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples of $1,000 only, provided that the unpurchased portion of the Notes of any Holder must be equal to $2,000 in principal amount or integral
multiples of $1,000 in excess thereof; 
 (6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer
will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying
Agent at the address specified in the notice at least three days before the Purchase Date; 
 (7) that Holders will be
entitled to withdraw their election if the Company, a depositary, if appointed by the Company, or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a 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 Trustee will select the Notes to be purchased in accordance with DTC procedures and the Company will select such other pari passu Indebtedness to be purchased 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 integral multiples of $1,000 in excess thereof, will be
purchased); and 

  
 46 

 (9) that Holders whose Notes were purchased only in part will be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
 On or before the
Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount
has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the
Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering
Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and
mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to
the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date. 
 Other than as
specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such
required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

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

The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with
Section 2.03 hereof. 
 Section 4.03 Reports.

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms
10-Q and 10-K if the Company were required to file such reports; and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if
the Company were required to file such reports. 
 All such reports will be prepared in all material respects in accordance with all of the
rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Company’s consolidated financial statements by its certified independent accountants. The
Company will electronically file a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the
SEC will not accept such a filing) and will post the reports on its or Parent’s website within those time periods. 
 If the SEC will
not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraph on its or its Parent’s website within the time periods that would apply if the Company were required to file those
reports with the SEC or post on its or its Parent’s website (after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Notwithstanding, the foregoing, if the Company
satisfies its obligations in the preceding sentence by posting reports on its or its Parent’s website, (a) the Company will not be required to furnish any information, certificates, or reports required by (i) Section 302 or
Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 or 308 of Regulation S-K, (ii) Regulation G or Item 10(e) of Regulation S-K promulgated by
the SEC with respect to any non-GAAP financial measures contained therein, or (iii) 

  
 48 

 
Rule 3-09 of Regulation S-X, (b) such reports will not be required to contain the separate financial
information for Guarantors contemplated by Rule 3-10 or Rule 3-16 of Regulation S-X promulgated under the Exchange Act (except
narrative disclosure of the assets, liabilities, revenues and operating income of any non-guarantor Subsidiaries shall be included) and (c) such reports shall not be required to present compensation or
beneficial ownership information. The Company will not take any action for the purpose of causing the SEC not to accept any such filing. 

(b) In the event that: 
 (1) the
rules and regulations of the SEC would permit the Company and Parent to report at Parent’s level on a consolidated basis if such entities were subject to Section 13 or 15(d) of the Exchange Act and Parent is not engaged in any business in
any material respect other than incidental to its ownership, directly or indirectly, of the capital stock of the Company; or 
 (2) Parent
becomes a Guarantor of the Notes, 
 consolidating reporting at Parent’s level in a manner consistent with that described in this
Section 4.03 the Company will satisfy this Section 4.03 and this Indenture will permit the Company to satisfy its obligations in this Section 4.03 with respect to financial information relating to the Company by furnishing financial
information relating to Parent; provided that such financial information is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to Parent and any of its Subsidiaries other than
the Company and its Subsidiaries, on the one hand, and the information relating to the Company, the Guarantors and the other Subsidiaries of the Company on a standalone basis, on the other hand. 

(c) For so long as any Notes remain outstanding, if at any time the Company and the Guarantors are not required to file with the SEC or post on
its or its Parent’s website the reports required by Section 4.03(a) hereof, the Company and the Guarantors will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 (d) Delivery of such reports, information and documents to the Trustee
hereunder is for informational purposes only and the Trustee’s receipt of such 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 hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates or certificates delivered pursuant to Section 4.04 hereof). The Trustee shall have no obligation whatsoever
to determine whether or not such information, documents or reports have been filed pursuant to the EDGAR filing system (or its successor) or postings to any website have occurred. The Trustee has no duty to participate in or monitor any conference
calls. 
 (e) Any and all Defaults or Events of Default arising from a failure to furnish or file in a timely manner any information or
report required by this Section 4.03 shall be deemed cured (and the Company shall be deemed to be in compliance with this Section 4.03) upon furnishing or filing such information or report as contemplated by this Section 4.03 (but
without regard to the date on which such information or report is so furnished or filed); provided that such cure shall not otherwise affect the rights of the Holders described under Section 6.01 if principal and interest have been accelerated
in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure. 

  
 49 

 Section 4.04 Compliance Certificate.  

(a) The Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 90
days after the end of each fiscal year, an Officer’s Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer with a view
to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every
covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events
of Default of which he or she may have knowledge) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited
or if such event has occurred, a description of the event. The Treasurer of the Company may not be the signing Officer for such an Officer’s Certificate. 

(b) So long as any of the Notes are outstanding, the Company will deliver to the Trustee, within 30 days of becoming aware of any Default or
Event of Default that has occurred and is continuing, a statement specifying such Default or Event of Default. 
 Section 4.05 Taxes. 

 The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and
governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders. 

Section 4.06 Stay, Extension and Usury Laws.  

Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will 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 wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and
each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 
 Section 4.07
Restricted Payments.  
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly: 
 (1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or
any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of
the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company); 

  
 50 

 (2) purchase, redeem or otherwise acquire or retire for value (including, without
limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company; 

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness of the Company or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantees (excluding any intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries), except a payment of
interest or a payment, purchase, redemption, defeasance or other acquisition or retirement in anticipation of satisfying a sinking fund obligation, principal installment or payment at final maturity, in each case due within one year of the date of
such payment, purchase, redemption, defeasance or other acquisition or retirement for value; or 
 (4) make any Restricted
Investment, 
 (all such payments and other actions set forth in clauses (1) through (4) of this Section 4.07(a) collectively being referred to as
“Restricted Payments”), 
 unless, at the time of and after giving effect to such Restricted Payment: 

(i) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; 

(ii) immediately after giving effect to such transaction on a pro forma basis, the Company could incur $1.00 of additional Indebtedness under
the Fixed Coverage Ratio Test in Section 4.09(a) hereof; and 
 (iii) such Restricted Payment, together with the aggregate amount of all
other Restricted Payments made by the Company and its Restricted Subsidiaries since the date of this Indenture (excluding Restricted Payments permitted by clauses (2) through (14) of Section 4.07(b) hereof), is less than the sum, without
duplication, of: 
 (a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period)
from April 7, 2011 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a
deficit, less 100% of such deficit); plus 
 (b) 100% of the aggregate net proceeds (including the Fair Market Value
of assets other than cash, including any Permitted Business) received by the Company since the date of this Indenture as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than
Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity
Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company); provided that any non-cash net proceeds shall be assets of the type used or useful in a Permitted Business;
plus 

  
 51 

 (c) an amount equal to the net reduction in or return on Investments (other than
Permitted Investments) made by the Company and its Restricted Subsidiaries subsequent to the date of this Indenture resulting from repurchases, repayments or redemptions of such Investments, proceeds realized on the sale of any such Investment and
proceeds representing the return of capital on any such Investment and dividends and distributions with respect thereto, in each case received by the Company or any of its Restricted Subsidiaries; provided, however, that, with respect
to any Investment, the foregoing sum shall not exceed the amount of such Investment; plus 
 (d) the amount by which
Indebtedness or Disqualified Stock incurred or issued since the date of this Indenture is reduced on the Company’s consolidated balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) into Capital Stock of the
Company that is not Disqualified Stock (less the amount of any cash, or the Fair Market Value of any other asset, distributed by the Company or any Restricted Subsidiary upon such conversion or exchange); provided that such amount will not
exceed the aggregate Net Proceeds received by the Company or any Restricted Subsidiary since the date of this Indenture from the issuance and sale (other than to a Subsidiary of the Company) of such Indebtedness or Disqualified Stock; plus

 (e) 100% of any dividends received by the Company or a Restricted Subsidiary of the Company after the date of this
Indenture from an Unrestricted Subsidiary of the Company, to the extent that such dividends were not otherwise included in the Consolidated Net Income of the Company for such period; provided, however, that the amount calculated
pursuant to this clause (e) may not exceed the aggregate amount of Restricted Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary since the date of this Indenture; plus 

(f) to the extent that any Unrestricted Subsidiary of the Company designated as such after the date of this Indenture is
redesignated as a Restricted Subsidiary after the date of this Indenture, in a transaction that is treated as a Restricted Investment (and not a Permitted Investment), the Fair Market Value of the Company’s Investment in such Subsidiary as of
the date of such redesignation provided that the amount calculated pursuant to this clause (f) may not exceed the aggregate amount of Restricted Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary
made since the date of this Indenture. 
 (b) The provisions of Section 4.07(a) hereof will not prohibit: 

(1) the payment of any dividend or the consummation of any irrevocable redemption within 90 days after the date of declaration
of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of this Indenture; 

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale
(other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to Company; provided that the amount of any such net
cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (ii)(b) of Section 4.07(a) hereof; 

(3) the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of the Company or any
Guarantor that is contractually subordinated to the Notes or to any Note Guarantee in exchange for, or with the net cash proceeds from a substantially concurrent incurrence of, Permitted Refinancing Indebtedness; 

  
 52 

 (4) the payment of any dividend (or, in the case of any partnership or limited
liability company, any similar distribution) by a Restricted Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis; 

(5) so long as no Default has occurred and is continuing or would be caused thereby, the repurchase, redemption or other
acquisition or retirement for value of any Equity Interests of the Company or the Parent held by any current or former officer, director or employee of the Company that directly or indirectly owns all of the outstanding Capital Stock of the Company
or the Parent (or permitted transferees of such officers, directors or employees) pursuant to any equity subscription agreement, stock option agreement, shareholders’ agreement or similar agreement or other agreement approved by the Board of
Directors; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $4.0 million in any twelve-month period, with unused amounts pursuant to this clause (5) being
carried over to the immediately succeeding twelve-month period; provided that in no event shall such amount exceed $8.0 million in any twelve-month period; 

(6) the repurchase of Equity Interests deemed to occur upon the exercise of stock options, warrants or other convertible
securities to the extent such Equity Interests represent all or a portion of the exercise price of those stock options, warrants or other convertible securities or are surrendered in connection with satisfying any federal or state income tax
withholding obligation related to any such exercise or vesting of any equity award; 
 (7) the declaration and payment of
regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any Restricted Subsidiary of the Company issued on or after the date of this Indenture in accordance with the test described in
Section 4.09 hereof; 
 (8) Permitted Payments to Parent; 

(9) payments made with respect to extinguishment of fractional shares (whether in connection with the exercise of warrants,

the aggregate; 
 (10) the purchase or acquisition of Equity Interests of the Company or Parent in open-market purchases, or
the payment of dividends to Parent for Parent to purchase or acquire its Equity Interests, in each case solely to provide for matching contributions of any employees of the Company, any of its Subsidiaries or Parent, pursuant to any deferred
compensation plan or other benefit plan in the ordinary course of business in an aggregate amount not to exceed $5.0 million in any calendar year; 

(11) the repurchase, redemption or other acquisition or retirement for value of preferred stock purchase rights issued in
connection with any shareholder rights plan that may be adopted by the Company or Parent not to exceed $500,000; 
 (12)
payments by the Company any Restricted Subsidiary in respect of Indebtedness of the Company or any Restricted Subsidiary owed to the Company or another Restricted Subsidiary; 

(13) other Restricted Payments in an aggregate amount since the date of this Indenture not to exceed the greater of (x)
$50.0 million and (y) 5.0% of Total Assets; and 

  
 53 

 (14) other Restricted Payments so long as, immediately after giving effect to
such Restricted Payment, the Total Net Leverage Ratio for the most recently ended four fiscal quarters for which internal financial statements are available as of the date immediately preceding such Restricted Payment is not greater than 3.00 to
1.00 on a pro forma basis; provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under this clause (14), no Default shall have occurred and be continuing or would occur as a consequence thereof. 

The amount of any Restricted Payment (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. For purposes of determining compliance with this Section 4.07, in the event that a payment or
other action meets the criteria of more than one of the exceptions described in clauses (1) through (14) of Section 4.07(b) hereof, or is entitled to be made pursuant to Section 4.07(a) hereof (including any payment or other action that
constitutes a “Permitted Investment”), the Company will be permitted to classify such payment or other action on the date of its occurrence in any manner that complies with this Section 4.07 (including any payment or other action that
constitutes a “Permitted Investment”). Payments or other actions permitted by this Section 4.07 need not be permitted solely by reference to one provision permitting such payment or other action (including any payment or other action
that constitutes a “Permitted Investment”), but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.07 permitting payment or other action (including any payment or other action
that constitutes a “Permitted Investment”).

refundings, replacements or refinancings, such amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such encumbrances and
restrictions, than those contained in those agreements on the date of this Indenture;

pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period; provided
that the amount of Indebtedness, Disqualified Stock and preferred stock that may be incurred or issued, as applicable, under this subsection (a) by Restricted Subsidiaries that are not Guarantors shall not exceed at any time outstanding the

used in the business of the Company or any of its Restricted Subsidiaries, provided that the aggregate principal amount of any such incurrence does not cause the aggregate principal amount of Indebtedness then outstanding under this clause
(4), including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), to exceed the greater of (x) $75.0 million and (y) 7.5% of Total

incurred under Section 4.09(a) hereof or clauses (2), (3), (4), (5), (14), or (19) 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:

Indebtedness must be 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 Guarantee, in the case of a Guarantor; and 

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a
Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company, will be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries

with the Notes, then such Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 

(10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’

Subsidiaries providing for indemnification, purchase price adjustment or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business or assets of the Company or any of its Restricted
Subsidiaries or Capital Stock of any of its Restricted Subsidiaries; provided that the maximum aggregate liability in respect of all such Indebtedness incurred pursuant to this clause (13) shall at no time exceed the gross proceeds
actually received by the Company and its Restricted Subsidiaries in connection with such acquisitions or dispositions; 

(14) the incurrence of Permitted Acquisition Debt; 

(15) the incurrence of Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of
business; 
 (16) the incurrence of Indebtedness consisting of take-or-pay obligations contained in supply agreements relating to products, services or commodities of a type that the Company or any of its Subsidiaries uses or sells in the ordinary course of business;

 (17) the incurrence of Indebtedness consisting of the financing of insurance premiums; 

  
 58 

 (18) the incurrence of Indebtedness consisting of Guarantees incurred in the
ordinary course of business under repurchase agreements or similar agreements in connection with the financing of sales of goods in the ordinary course of business; and 

(19) the incurrence by the Company or any Restricted Subsidiary of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (19), not to exceed the
greater of (x) $75.0 million and (y) 7.5% of Total Assets as of the date of any such incurrence. 
 The Company will not incur, and the
Company will not permit any Guarantor to, directly or indirectly, incur any Indebtedness (including Acquired Debt) that is subordinated or junior in right of payment to any Indebtedness of the Company or such Guarantor, as the case may be, unless
such Indebtedness is expressly subordinated in right of payment to the Notes or such Guarantor’s Note Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or such Guarantor, as
the case may be; provided, however, that (1) unsecured Indebtedness will not be deemed or treated as subordinated or junior to secured Indebtedness merely because it is unsecured or is secured by different collateral or
(2) Senior Debt will not be deemed or treated as subordinated or junior to any other Senior Debt merely because it has a junior priority with respect to the same collateral. 

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of
more than one of the categories of Permitted Debt described in clauses (1) through (19) 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 this Section 4.09. Indebtedness permitted by this Section 4.09 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.09 permitting such Indebtedness. Indebtedness under the Credit Agreement outstanding on the date on
which Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest,
the accretion or amortization of original issue discount, 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, the payment of fees and premiums and additional payments with respect to Indebtedness, the realization of any Permitted Lien, a change in GAAP or an interpretation thereunder that results in an obligation of such Person that exists at
such time becoming Indebtedness, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock
for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual of interest, accretion or amortization of original issue discount or payment of interest is included in Fixed Charges of the Company as
accrued, accreted or paid, as the case may be. 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. For purposes of determining compliance with, and the outstanding principal amount of, any particular Indebtedness incurred pursuant to this
Section 4.09, any other obligation of the obligor on such Indebtedness (or of any other Person that could have incurred such Indebtedness under this Section 4.09) arising under any Guarantee, Lien or letter of credit, bankers’
acceptance or other similar instrument or obligation supporting such Indebtedness shall be disregarded to the extent that such Guarantee, Lien or letter of credit, bankers’ acceptance or other similar instrument or obligation secures the
principal amount of such Indebtedness. 

  
 59 

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

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

(b) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 

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

(i) the Fair Market Value of such assets at the date of determination; or 

(ii) the amount of the Indebtedness of the other Person. 

Section 4.10 Asset Sales.  
 (a) The
Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the
Company (or the applicable Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests sold or issued 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 shall be deemed to be cash: 
 (A) any
liabilities, as shown on the Company’s most recent internal 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 Guarantee)
that are unconditionally assumed by the transferee of any such assets to the extent that the Company or the applicable Restricted Subsidiary is released from all liability with respect thereto; 

(B) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee
that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents within 90 days after receipt, to the extent of the cash or Cash Equivalents received in that conversion; 

(C) any Designated Noncash Consideration received by the Company or any Restricted Subsidiary in such Asset Sale having an
aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause (C) since the date of this Indenture, not to exceed the greater of (x) $30.0 million and (y) 3.0% of Total Assets
at the time of the receipt of such Designated Noncash Consideration, with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value; 

  
 60 

 (D) any stock or assets of the kind referred to in clauses (2) or (4) of
Section 4.10(b) hereof; and 
 (E) a combination of the consideration specified in the foregoing clauses (A) through (D)
of this Section 4.10(a). 
 (b) Within 365 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 at its option: 
 (1) to repay Senior Debt that is
secured by a Lien, which Lien is permitted by this Indenture; 
 (2) to acquire all or substantially all of the assets of, or
any Capital Stock of, another Permitted Business, provided that, in the case of any such acquisition of Capital Stock, the Permitted Business is or becomes or is merged with or into a Restricted Subsidiary of the Company; 

(3) to make a capital expenditure; 

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted
Business; 
 (5) to repay other Senior Debt; provided that to the extent the Company (or the applicable Restricted
Subsidiary, as the case may be) reduces Obligations under Senior Debt other than the Notes, the Company shall equally and ratably reduce Obligations under the Notes pursuant to Section 3.07 through open-market purchases (to the extent such
purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth in Section 3.09) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount
of accrued and unpaid interest and Special Interest, if any, on the amount of Notes to be prepaid; or 
 (6) a combination of
repayments, acquisitions and expenditures permitted by the immediately foregoing clauses (1) through (5) of this Section 4.10(b); 
 provided
that, in the case of clauses (2), (3) and (4) above of this Section 4.10(b), a binding commitment entered into not later than such 365th day will extend the period for such investment or other payment for up to an additional 180 days after the
end of such 365-day period so long as the Company or a Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within
such 180 days (an “Acceptable Commitment”). In the event an Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith but after the end of the original 365-day period, then such Net Proceeds will be deemed to constitute Excess Proceeds on the date of such cancellation or termination. In addition to the foregoing, at any time and on one or more occasions prior to
such 365th day (as extended, if applicable), the Company in its sole discretion may apply Net Proceeds from one or more Asset Sales to make an Asset Sale Offer as described below in this Section 4.10. 

Pending the final application of any Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by this Indenture. 

  
 61 

 Any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses
(1) through (6) of Section 4.10(b) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $40.0 million (or such lesser amount that the Company determines), 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 containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds
of sales of assets in accordance with Section 3.09 hereof to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer
will be equal to 100% of the principal amount plus accrued and unpaid interest and Special Interest, if any, to the date of purchase 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 into such Asset Sale Offer exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes to be purchased in accordance with DTC procedures applicable to Global Notes and the Company will select such other pari passu Indebtedness to be purchased on a pro rata basis. 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 such 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 3.09 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 3.09 hereof or this Section 4.10 by virtue of such compliance. 
 Section 4.11
Transactions with Affiliates.  
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any
payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee
with, or for the benefit of, any Affiliate of the Company (each an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $10.0 million, 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 in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 

(2) the Company delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $25.0 million, either (a) a resolution of the Board of Directors of the Company set forth in an Officer’s 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 or (b) an opinion as to the fairness to the Company or such Subsidiary of
such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 

  
 62 

 (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, employee benefit plan, officer or
director indemnification agreement, or any similar arrangement (including vacation plans, health and life insurance plans, deferred compensation plans, retirement or savings plans, and stock option, stock ownership and similar plans) entered into by
the Company or any of its Restricted Subsidiaries, any payment of compensation (including awards or grants in cash, securities or other payments) for the personal service of officers and employees of the Company or any of its Restricted Subsidiaries
and payments of reasonable directors fees, in each case entered into or paid by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto; 

(2) transactions between or among the Company and/or its Restricted Subsidiaries; 

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company
solely because the Company owns or controls, directly or through a Restricted Subsidiary, an Equity Interest in such Person; 

(4) any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company; 

(5) loans and advances to officers, directors or employees of the Company or any of its Restricted Subsidiaries made in the
ordinary course of business; provided that such loans and advances do not exceed $5.0 million in the aggregate at any one time outstanding; 

(6) Restricted Payments that do not violate Section 4.07 hereof and Investments that constitute Permitted Investments;

 (7) Permitted Payments to Parent; 

(8) purchases and sales of raw materials or inventory in the ordinary course of business on market terms; 

(9) transactions between the Company or any Restricted Subsidiary and any joint venture or Unrestricted Subsidiary of the
Company entered into in the ordinary course of business; provided that such transactions are on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable
transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (10) any transaction arising out of
an agreement existing on the date of this Indenture and described in the “Related Party Transactions” section of the Offering Memorandum and any amendment thereto or replacement thereof that, taken as a whole, is no less favorable to the
Company than the agreement as in effect on the date of this Indenture. 
 Section 4.12 Liens. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause to become effective
any Lien of any kind (other than Permitted Liens) securing Indebtedness, or Attributable Debt upon any of their property or assets, now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured (a) in
the case of any Senior Debt so secured, on an equal and ratable basis with the Obligations so secured until such time as such Obligations are no longer secured by a Lien and (b) in the case of any subordinated Indebtedness so secured, on a
senior basis with the Obligations so secured until such time as such Obligations are no longer secured by a Lien. Any Lien created for the benefit of the Holders of the Notes pursuant to this Section 4.12 will provide by its terms that such
Lien will be automatically and unconditionally released and discharged upon the release and discharge of the initial Lien giving rise to such Lien. 

  
 63 

 Section 4.13 [Intentionally Omitted.] 

Section 4.14 Corporate Existence.  

Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect: 

(1) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with
the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and 

(2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however,
that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders. 

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 integral multiples 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 and Special Interest, if any, on the Notes repurchased to, but not including, the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the
“Change of Control Payment”); provided that the unrepurchased portion of the Notes of any Holder must be equal to $2,000 in principal amount or integral multiples of $1,000 in excess thereof. Within 30 days following any
Change of Control, the Company will deliver a notice to each Holder and the Trustee 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 delivered (the “Change of Control Payment Date”); 
 (3) that any
Note not tendered will continue to accrue interest; 
 (4) that, unless the Company defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the
Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date; 

  
 64 

 (6) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a 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 his 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 integral multiples of $1,000 in excess
thereof. 
 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 pursuant to a Change of Control Offer. To the extent that the provisions of any securities
laws or regulations conflict with the provisions of Sections 3.09 or 4.15 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or
this Section 4.15 by virtue of such compliance. 
 (b) On 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 and not withdrawn pursuant to the Change of
Control Offer; 
 (2) deposit with the Paying Agent (or, if the Company or any of its Restricted Subsidiaries or Parent is
acting as Paying Agent, segregate and hold in trust) 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 Officer’s Certificate
stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 Upon receiving the Change of Control
Payment from the Company, the Paying Agent will promptly deliver (but in any case not later than five 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 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; provided that each new Note must be
equal to $2,000 in principal amount or integral multiples of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

(c) Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon
a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and Section 3.09 hereof 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 3.07 hereof, unless and until there is a default in payment of the applicable redemption price. 

  
 65 

 (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. 

(e) If Holders of not less than 90% of the aggregate principal amount of the outstanding Notes properly tender and do not withdraw such Notes
in a Change of Control Offer and the Company, or any other Person making a Change of Control Offer in lieu of the Company, as discussed above, purchases all of the Notes properly tendered and not withdrawn by such Holders, the Company or such Person
will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all Notes that remain outstanding following such purchase at
a redemption price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, to, but excluding, the date of redemption. 

Section 4.16 [Intentionally Omitted.] 

Section 4.17 Limitation on Sale and Leaseback Transactions.  

The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided
that the Company or any Guarantor may enter into a sale and leaseback transaction if: 
 (1) the Company or that Guarantor,
as applicable, could have incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the Fixed Charge Coverage Ratio test in Section 4.09(a) hereof; and 

(2) the transfer of assets in that sale and leaseback transaction does not violate, and the Company applies the proceeds of
such transaction in compliance with, Section 4.10 hereof. 
 Section 4.18 [Intentionally Omitted.] 

Section 4.19 [Intentionally Omitted.]  

Section 4.20 Additional Note Guarantees. 

If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the date of this Indenture, and such
Domestic Subsidiary Guarantees the Company’s obligations under any Credit Facility, then the Company will cause that newly acquired or created Domestic Subsidiary to execute a notation of Note Guarantee pursuant to a supplemental indenture
substantially in the form of Exhibit F hereto, in form and substance satisfactory to the Trustee and deliver an Opinion of Counsel to the Trustee within 30 Business Days of the date on which it was acquired or created (or ceased to be an Immaterial
Subsidiary, to the extent applicable) to the effect that such supplemental indenture has been duly authorized, executed and delivered by that Domestic Subsidiary and constitutes a valid and binding agreement of that Domestic Subsidiary, enforceable
in accordance with its terms (subject to customary exceptions); provided that any Domestic Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it ceases to be an Immaterial Subsidiary. The form
of notation of such Note Guarantee is attached as Exhibit E hereto. 

  
 66 

 Section 4.21 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 and if that designation otherwise is consistent with the definition of an Unrestricted Subsidiary. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments
owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and that designation will only be permitted if the Investment
would be permitted at that time (either as a Restricted Payment or as a Permitted Investment). 
 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 Officer’s 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 unless such Unrestricted Subsidiary is made to meet such requirements. 

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; 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 four-quarter reference period; and (2) no Default or Event of Default would be in existence
following such designation. 
 Section 4.22 Changes in Covenants if Notes Rated Investment Grade 

(a) If at any time following the date of this Indenture, (i) the Notes are rated Investment Grade by each of S&P and Moody’s (or,
if either (or both) of S&P and Moody’s have been substituted in accordance with the definition of “Rating Agencies,” by each of the then applicable Rating Agencies), (ii) no Default has occurred and is continuing under this
Indenture and (iii) the Company has delivered to the Trustee an Officer’s Certificate certifying the foregoing provisions in this Section 4.22(a) then, beginning on that day and subject to the provisions of the following paragraphs,
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.20 and 5.01(a)(4) hereof will be suspended (the “Suspension Period”). During any Suspension Period, the Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant
to Section 4.21 hereof. 
 (b) If the rating assigned to the Notes by either Rating Agency should subsequently decline to below
Investment Grade, the foregoing covenants will be reinstituted as of and from the date of such rating decline (the “Reversion Date”). Calculations under the reinstated Section 4.07 hereof will be made as if Section 4.07
hereof had been in effect since the date of this Indenture except that no Default will be deemed to have occurred solely by reason of a Restricted Payment made while Section 4.07 hereof was suspended. Furthermore, all Debt incurred during the
Suspension Period will be deemed to have been incurred or issued pursuant to Section 4.09(b)(2) hereof. Notwithstanding that the suspended covenants may be reinstated, no Default will be deemed to have occurred as a result of a failure to comply
with such suspended covenants during any Suspension Period (or upon termination of any covenant Suspension Period or after that time based solely on events that occurred during the Suspension Period). 

  
 67 

 (c) The Company shall promptly deliver to the Trustee an Officer’s Certificate notifying the
Trustee of any event giving rise to a Suspension Period or a Reversion Date, the date of this Indenture and identifying the suspended covenants. The Trustee shall not have any obligation to monitor the ratings of the Notes or to notify holders of
the occurrence of dates of any Suspension Period, suspended covenants or Reversion Date. 
 ARTICLE 5 

SUCCESSORS 
 Section 5.01 Merger,
Consolidation, or Sale of Assets. 
 (a) The Company shall not, directly or indirectly: (i) consolidate or merge with or into
another Person (whether or not the Company is the surviving corporation); or (ii) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken
as a whole, in one or more related transactions, to another Person, unless: 
 (1) either: 

(a) the Company is the surviving corporation; or 

(b) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, conveyance or other disposition has been made is an entity organized or existing under the laws of the United States, any state of the United States or the District of Columbia or any territory thereof (the Company or such
Person, as the case may be, being herein called the “Successor Company”); provided that in the event that the Successor Company is not a corporation, a co-obligor of the Notes is a corporation; 

(2) the Successor Company (if other than the Company) assumes all the obligations of the Company under the Notes, this
Indenture and the Registration Rights Agreement (if the Company’s registration obligations thereunder have not been completed) pursuant to a supplemental indenture reasonably satisfactory to the Trustee; 

(3) immediately after such transaction, no Default or Event of Default exists; 

(4) the Successor Company would, on the date of such transaction after giving pro forma effect thereto and any related
financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section
4.09(a) hereof and or (b) have a Fixed Charge Coverage Ratio that is no less than the Fixed Charge Coverage Ratio of the Company immediately prior to such transaction; and 

(5) the Successor Company delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that
all conditions precedent have been complied with. 
 In addition, the Company will not, directly or indirectly, lease all or substantially
all of its and its Restricted Subsidiaries’ properties or assets, taken as a whole, in one or more related transactions, to any other Person.

Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the
properties or assets of the Company and its Restricted Subsidiaries taken as a whole in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, the successor Person formed by such consolidation or into
or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale,
assignment, transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the
Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest
on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof.

failure to pay principal on such Indebtedness at Stated Maturity after giving effect to any grace period (a “Payment Default”); or 

(b) results in the acceleration of such Indebtedness prior to its Stated Maturity, and, in each case, the principal amount of
any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or more and such Indebtedness has

 Section 6.02 Acceleration. 

In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Company,
all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding
Notes may by written notice to the Company declare all the Notes to be due and payable immediately. 
 Upon any such declaration, the Notes
shall become due and payable immediately. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by
written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal,
interest or premium, if any, or Special Interest, if any, that has become due solely because of the acceleration) have been cured or waived and all amounts owing to the Trustee under this Indenture have been paid. 

Section 6.03 Other Remedies. 
 If an
Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and Special Interest, if any, and interest on the Notes or to enforce the performance of any provision of
the Notes or this Indenture. 
 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 of a Note 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. All remedies are cumulative to the extent permitted by law. 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 Guarantors, 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. 

  
 71 

 Section 6.04 Waiver of Past Defaults. 

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the
Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Special Interest, if any, or interest on, the
Notes, including in connection with an offer to purchase (other than the non-payment of interest or premium, if any, or Special Interest, if any, on, or principal of, the Notes that become due solely because
of the acceleration of the Notes); provided, however, that the Holders of not less than a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment
default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other Default or impair any right consequent thereon. 
 Section 6.05 Control by Majority. 

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of
conducting any proceeding for exercising 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 that the Trustee
determines may be unduly prejudicial to the rights of other Holders of Notes (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders) or that may
involve the Trustee in personal liability. The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

Section 6.06 Limitation on Suits. 
 A
Holder may pursue a remedy with respect to this Indenture or the Notes only if: 
 (1) such Holder gives to the Trustee
written notice that an Event of Default is continuing; 
 (2) 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 and,
if requested, provide to the Trustee security or indemnity satisfactory 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) during such 60-day period, Holders of a majority in aggregate
principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 
 A Holder of a Note may
not use this Indenture to 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 of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and
Special Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer or Change of Control Offer), or to bring suit for the enforcement of any such payment on
or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

  
 72 

 Section 6.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover
judgment in its own name and as trustee of an express trust against the Company or any Guarantor for the whole amount of principal of, premium and Special Interest, if any, and interest remaining unpaid on, the Notes and interest on overdue
principal and, to the extent lawful, interest 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. 

The Trustee is authorized to 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 of the Notes allowed in any judicial proceedings relative to the Company or any
Guarantor (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian 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
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, 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 properties that the Holders may be entitled to receive in such proceeding 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 accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes
or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a
member of a creditors’ committee or other similar committee. 
 Section 6.10 Priorities. 

After an Event of Default, any moneys or properties distributable in respect of the Company’s or any Guarantor’s obligations under
this Indenture, or if the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money and property in the following order: 

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all
compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and Special Interest, if any,
and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and Special Interest, if any, and interest, respectively; and 

  
 73 

 Third: to the Company or any other obligors on the Notes, including the
Guarantors, or to such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for
any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as a 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, 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 by the Trustee, a suit by a Holder of a Note pursuant
to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

 TRUSTEE 
 Section 7.01 Duties
of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested
in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) Except during the continuance of an Event of Default: 

(1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need
perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions specifically required to be
furnished to it under this Indenture to determine whether or not they substantially conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

 74

to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof or any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders a majority in principal amount of
the outstanding Notes in the exercise of any trust or power conferred upon the Trustee. 
 (d) Whether or not therein expressly so provided,
every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01. 

(e) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under

as otherwise set forth in this Indenture, before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good
faith in reliance on such Officer’s Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability

 (c) The Trustee may act through
its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care.

this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with
such request or direction. 

  
 75 

 (g) The Trustee shall not be required to give any bond or surety in respect of the performance or
exercise of its powers or duties hereunder.

Event of Default unless the Trustee shall have received from the Company, any Guarantor or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 13.02 hereof, and such notice references
the Notes and this Indenture. In the absence of any such notice, the Trustee may conclusively assume that no Default or Event of Default exists. 

(i) The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be
compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder as Agent, and to each agent, custodian and other Person employed to act hereunder. 

(j) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out
of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and
interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, or other unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility; it being understood that
the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

(k) In no event shall the Trustee be responsible or liable for any special, indirect, punitive or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit), irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(m) The Trustee will not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness, or other paper or document, or inquire as to the performance by the Company or the Guarantors of any of their covenants
or obligations in this Indenture, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may reasonably see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it will be entitled to examine the books, records, and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such
inquiry or investigation. 
 (n) For certain payments made pursuant to this Indenture, the Trustee or the Paying Agent may be required to
make a “reportable payment” or “withholdable payment” and in such cases the Trustee or the Paying Agent shall have the duty to act as a payor or withholding agent, respectively, that is responsible for any tax withholding and
reporting required under Chapters 3, 4, and 61 of the Code. The Trustee or the Paying Agent shall have the sole right to make the determination (to be reasonably determined in good faith) as to which payments are “reportable payments” or
“withholdable payments.” All parties to this Indenture shall provide an executed Internal Revenue Service Form W-9 or appropriate Internal Revenue Service Form
W-8 (or, in each case, any successor form) to the Trustee or the Paying Agent prior to closing, and upon request by the Trustee or the Paying Agent, shall promptly update any such form to the extent such form
becomes obsolete or inaccurate in any respect. The Trustee or the Paying 

  
 76 

 
Agent shall have the right to request from any party to this Indenture, or any other Person entitled to payment hereunder, any additional forms, documentation or other information as may be
reasonably necessary for the Trustee or the Paying Agent to satisfy its reporting and withholding obligations under the Code. To the extent any such forms to be delivered under this Section 7.02(n) are not provided prior to or by the time the
related payment is required to be made or are reasonably determined in good faith by the Trustee or the Paying Agent to be incomplete and/or inaccurate in any respect, the Trustee or the Paying Agent shall be entitled to withhold on any such
payments hereunder to the extent withholding is required under Chapters 3, 4, or 61 of the Code, and shall have no obligation to gross up any such payment. 

Section 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest, as defined in the TIA, it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee (if this Indenture has been qualified under the TIA and to the extent permitted by TIA § 3.10(b)) or resign. If the Trustee fails to eliminate the conflicting interest, obtain permission or resign within 10
days of the expiration of the 90-day period, the Trustee is required to notify the Holders to this effect, and any Holder that has been a bona fide Holder for at least six months may petition a court to remove
the Trustee and appoint a successor trustee. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 

Section 7.04 Trustee’s Disclaimer. 

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes or the Note
Guarantees, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant
to this Indenture other than its certificate of authentication and the Statement of Eligibility on Form T-1 to be supplied to the Company in connection with the Exchange Offer Registration Statement and/or
Shelf Registration Statement. The Trustee shall not be bound to ascertain or inquire as to the performance, observance, or breach of any covenants, conditions, representations, warranties or agreements on the part of the Company or the Guarantors
but the Trustee may require full information and advice as to the performance of the aforementioned covenants. Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes or the Note
Guarantees. The Trustee makes no representation as to and shall not be responsible for any statement or recital herein or any statement in the Offering Memorandum, Exchange Offer Registration Statement and/or Shelf Registration Statement or any
other document in connection with the sale or exchange of the Notes. The Trustee shall not be responsible for and makes no representation as to any act or omission of any Rating Agency or any rating with respect to the Notes. The Trustee shall have
no obligation to independently determine or verify if any event has occurred or notify the Holders of any event dependent upon the rating of the Notes, or if the rating on the Notes has been changed, suspended or withdrawn by any Rating Agency. The
Trustee shall have no obligation to independently determine or verify if any Change of Control or any other event has occurred or notify the Holders of any such event.     

  
 77 

 Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if it is known to a Responsible Officer of the Trustee, the Trustee will mail or
deliver to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or Special Interest, if any, or interest on, any
Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 

Section 7.06 Reports by Trustee to Holders of the Notes. 

(a) Within 60 days after each October 15 beginning October 15, 2017, and for so long as Notes remain outstanding, the Trustee will
deliver to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit or deliver all reports as required by TIA § 313(c). 

(b) A copy of each report at the time of its delivery to the Holders of Notes will be delivered by the Trustee to the Company and filed by the
Trustee with the SEC, if required, and each stock exchange on which the Notes are listed, if any, in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any stock exchange. 

Section 7.07 Compensation and Indemnity. 

(a) The Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder
as agreed in writing with the Company. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

(b) The Company and the Guarantors will, jointly and severally, indemnify the Trustee against any and all losses, liabilities or expenses
incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this
Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except
to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct as finally adjudicated by a court of competent jurisdiction. The Trustee will notify the Company promptly of any claim for which it may
seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense.
The Trustee may have separate counsel if it determines in good faith that an actual or potential conflict of interest makes joint representation by the Company’s counsel inappropriate, and the Company will pay the reasonable fees and expenses
of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. Neither the Company nor any Guarantor need reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through its own negligence or willful misconduct as finally adjudicated by a court of competent jurisdiction. All indemnifications and releases from liability granted hereunder to the Trustee shall
extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns. 

  
 78 

 (c) The obligations of the Company and the Guarantors under this Section 7.07 will survive
the resignation or removal of the Trustee and satisfaction and discharge of this Indenture. 
 (d) To secure the Company’s and the
Guarantors’ payment obligations in this Section 7.07, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes.
Such Lien will survive the satisfaction and discharge of this Indenture. 
 (e) When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law. 
 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 

(g) “Trustee” for the purposes of this Section 7.07 shall include any predecessor Trustee and the Trustee in each of its

months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will deliver a notice of its succession to
Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 

Section 7.09 Successor Trustee by Merger, etc.

corporation, the successor corporation without any further act will be the successor Trustee.

America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least

 ARTICLE 8 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may, at its option and at any time, elect to have either Sections 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8. 

  
 80 

 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 Guarantees) on and after the
date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes (including the Note Guarantees), 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 such Notes, the Note Guarantees and this Indenture (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 or premium and Special Interest, if any, 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 2 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) Sections 8.01, 8.02, 8.04, 8.05, 8.06 and 8.07 of this Article 8. 

Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise
of its option under Section 8.03 hereof. If the Company exercises its Legal Defeasance option, each Guarantor will be released from all of its obligations with respect to its Note Guarantee. 

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 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.15, 4.17, 4.19,
4.20, 4.21 hereof and clause (4) of Section 5.01(a) hereof with respect to the outstanding Notes (including the Note Guarantees) 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 Guarantees, 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 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees 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, the events described in Sections 6.01(3) through 6.01(5) hereof will not constitute Events of Default.

  
 81 

 Section 8.04 Conditions to Legal or Covenant Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 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, expressed in a written certification thereof delivered to the Trustee if Government Securities are delivered, to pay the principal of, or interest and premium, if any, and Special Interest, if any, 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 will 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 be 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); 
 (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) to which the Company or any of its Subsidiaries is a party or by which the Company or
any of its Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officer’s Certificate stating that
the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 

  
 82 

 (7) the Company must deliver to the Trustee an Officer’s 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. 

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the
proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in
trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and Special Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or
pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, any of its Subsidiaries or Parent, in trust for the
payment of the principal of, premium or Special Interest, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or Special Interest, if any, or interest has become due and payable shall,
subject to applicable abandoned property law, be paid to the Company on its request or (if then held by the Company, any of its Subsidiaries or Parent) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to
look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment, may 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 8.07 Reinstatement. 
 If the
Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, 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 and the Notes and

  
 83 

 
the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or Special Interest, if any, or interest on, any Note
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 or Paying Agent. 

ARTICLE 9 
 AMENDMENT,
SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 

Notwithstanding Section 9.02 hereof, the Company, the Guarantors (except that no existing Guarantor need execute a supplemental indenture
substantially in the form of Exhibit F hereto pursuant to clause (8) of this Section 9.01) and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of any Holder to: 

(1) cure any ambiguity, defect or inconsistency; 

(2) provide for uncertificated Notes in addition to or in place of certificated Notes; 

(3) provide for the assumption of the Company’s or a Guarantor’s obligations to Holders and Note Guarantees by a
successor to the Company or such Guarantor pursuant to Article 5 or Article 11 hereof; 
 (4) make any change that would
provide any additional rights or benefits to Holders or that does not adversely affect the legal rights hereunder of any Holder; 

(5) comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 

(6) conform the text of this Indenture, the Note Guarantees or the Notes to any provision of the “Description of
Notes” section of the Company’s Offering Memorandum, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees or the Notes;

 (7) provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the
date of this Indenture; 
 (8) allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect
to the Notes; or 
 (9) evidence and provide for the acceptance of appointment under this Indenture of a successor Trustee.

 Upon the request of the Company and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will
join with the Company and, if applicable, the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be
therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

  
 84 

 Section 9.02 With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Company, the Guarantors and the Trustee may amend or supplement this Indenture
(including, without limitation, Sections 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without
limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any
existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or Special Interest, if any, or interest on, the Notes, except a payment default resulting from an acceleration that
has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without
limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which
Notes are considered to be “outstanding” for purposes of this Section 9.02. 
 Upon the request of the Company and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the
Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may
in its discretion, but will not be obligated to, enter into such amended or supplemental indenture. 
 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 it is sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will deliver to the Holders of Notes
affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to deliver such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or
supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company
with any provision of this Indenture or the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed maturity of any Note, or
reduce any amount payable on any redemption of the Notes or the initial non-call periods during which the Notes may not be redeemed; 

(3) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 

(4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or Special Interest, if any, or
interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

  
 85 

 (5) make any Note payable in money other than that stated in the Notes; 

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or interest or premium, if any, or Special Interest, if any, on, the Notes; 
 (7) waive a
redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.15 hereof); 
 (8)
release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 

(9) make any change to, or modify the ranking of, the Notes that would adversely affect the Holders of the Notes; or 

(10) make any change in the preceding amendment and waiver provisions in Sections 9.01 and 9.02. 

Section 9.03 Compliance with Trust Indenture Act. 

Every amendment or supplement to this Indenture or the Notes will be set forth in an amended or supplemental indenture that complies with the
TIA as then in effect. 
 The Company may, in the circumstances permitted by the TIA, set any day as the record date for the purpose of
determining the Holders of outstanding Notes entitled to give or take any request, demand, authorization, direction, notice, consent, waiver, or other action provided or permitted by this Indenture to be given or taken by Holders of the Notes. 

Section 9.04 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note 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 of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms
and thereafter binds every Holder. 
 Section 9.05 Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. Alternatively, the
Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

  
 86 

 Section 9.06 Trustee to Sign Amendments, etc. 

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors of the Company approves it. In executing any amended or supplemental indenture,
the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officer’s Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that it will be the legal, valid and binding obligation of the Company and the Guarantors in accordance with its terms.

 [INTENTIONALLY
OMITTED.] 
 ARTICLE 11 

NOTE GUARANTEES 
 Section 11.01
Guarantee. 
 (a) Subject to this Article 11, 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,
that: 
 (1) the principal of, premium, if any, and Special Interest, if any, and interest on, the Notes will be promptly
paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, 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 

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will 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, to the fullest extent permitted by applicable law, 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 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, to the fullest extent permitted by
applicable law, 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 covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 

  
 87 

 (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 Guarantee, 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 guaranteed 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 6 hereof for the purposes of this Note Guarantee, 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 6 hereof, such obligations (whether or not due and payable) will
forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. 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 Guarantee. 
 Section 11.02 [Intentionally Omitted.] 

Section 11.03 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
Guarantee 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 Guarantee. 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 11, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. 

Section 11.04 Execution and Delivery of Note Guarantee. 

To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee
substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its
Officers. 
 Each Guarantor hereby agrees that its Note Guarantee 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 Guarantee. 
 If an Officer whose signature is on this
Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set
forth in this Indenture on behalf of the Guarantors. 

  
 88 

 In the event that the Company or any of its Restricted Subsidiaries creates or acquires any
Domestic Subsidiary after the date of this Indenture, if required by Section 4.20 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.20 hereof and this Article 11, to the extent applicable.

 Section 11.05 Guarantors May Consolidate, etc., on Certain Terms. 

Except as otherwise provided in Section 11.06 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets
to, or 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) immediately after giving effect to such transaction, no Default or Event of Default exists; and 

(2) either: 

(a) (i) such Guarantor shall be the Person surviving any such consolidation or merger or (ii) the Person acquiring
the assets in any such sale or other disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture, its Note Guarantee and the Registration Rights
Agreement (if such Guarantor’s registration obligations thereunder have not been completed) on the terms set forth herein or therein, pursuant to a supplemental indenture satisfactory to the Trustee; or 

(b) such sale or other disposition does not violate Section 4.10 hereof. 

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture,
executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the
Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees 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 Guarantees so issued will in all respects have the same legal rank and benefit under this

entirety to the Company or another Guarantor.

way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted
Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, 

  
 89 

 
of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor)
will be released and relieved of any obligations under its Note Guarantee; provided that the Net Proceeds of such sale or other disposition are applied in accordance with the provisions of Section 4.10 hereof. Upon delivery by the
Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of Section 4.10 hereof, the Trustee will execute any
documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee. 
 (b) Upon
designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be released and relieved of any obligations under its Note Guarantee. 

(c) Upon defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 12 hereof,
each Guarantor will be released and relieved of any obligations under its Note Guarantee. 
 (d) Upon the release of such Restricted
Subsidiary’s Guarantees under all Credit Facilities of the Company (other than a release as a result of payment under or a discharge of such Guarantee), each Guarantor will be released and relieved of any obligations under its Note Guarantee.

 Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.06 will remain liable for
the full amount of principal of and interest and premium, if any, and Special Interest, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11. 

ARTICLE 12 
 SATISFACTION
AND DISCHARGE 
 Section 12.01 Satisfaction and Discharge. 

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 

(1) either: 

(a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes
for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the
delivery of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely 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, expressed in a written certification thereof delivered to the Trustee if Government Securities are delivered, without consideration of any reinvestment of interest, to pay and discharge the entire
Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and Special Interest, if any, and accrued interest to the date of maturity or redemption; 

  
 90 

 (2) no Default or Event of Default has 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 the deposit will not result in a breach or violation of, or constitute a default under, any other material agreement or
instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 
 (3) the
Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and 
 (4) the Company
has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the Redemption Date, as the case may be. 

In addition, the Company must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to
satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money has been
deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 12.01, the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those
provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 
 Section 12.02
Application of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee
pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Special Interest, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be
segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 12.01 hereof 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, the
Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Company has made any payment
of principal of, premium or Special Interest, if any, 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 such payment from the money or
Government Securities held by the Trustee or Paying Agent.

 SUPPLEMENTAL INDENTURE (this “Supplemental
Indenture”), dated as of                         , 20        , among
                                        (the
“Guaranteeing Subsidiary”), a subsidiary of Park-Ohio Industries, Inc. (or its permitted successor), an Ohio corporation (the “Company”), the Company and Wells Fargo Bank, National Association, as trustee under the
Indenture referred to below (the “Trustee”). 
 W I T N E S S E T H 

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of
April 17, 2017 providing for the issuance of 6.625% Senior Notes due 2027 (the “Notes”); 
 WHEREAS, the Indenture
provides that, under certain circumstances, the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s
Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and 

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged,
the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows: 
 1.
CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 

2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional
Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 11 thereof, and a notation of such Note Guarantee in the Form of Exhibit E to the Indenture.

Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 

4. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. Signatures of the parties hereto transmitted by facsimile or PDF may be used in lieu of the originals shall be deemed to be their original
signatures for all purposes. 
 6. EFFECT OF HEADINGS. The Section headings herein are for
convenience only and shall not affect the construction hereof. 
 7. THE TRUSTEE. The Trustee makes no
representation as to and shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture, the Note Guarantee of the Guaranteeing Subsidiary, or for or in respect of the recitals
contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Company.

(2) the Redemption Date; 

(3) the principal amount of Notes to be redeemed; and

(b) Amendment to Section 3.03. Subject to Section 2.01 hereof, Section 3.03 of Article 3 of

 2 

 
defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12. Notes called for redemption become due on the Redemption Date, provided that notices of

such condition precedent shall not have occurred, and thereafter such redemption and notice of redemption shall be rescinded and of no force or effect. Upon receipt of such notice from the Company rescinding such redemption, the Trustee will

(2) the redemption price (or manner of calculation if not then known); 

(3) 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 surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note or, if the Note is a Global Note, an adjustment will be made to the schedule
attached thereto; 
 (4) the name and address of the Paying Agent; 

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

which the Notes called for redemption are being redeemed; 
 (8) any conditions precedent to such redemption; and 

(9) that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or similar number, if any, listed in
such notice or printed on the Notes. 
 At the Company’s request, the Trustee will give the notice of redemption in the
Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least three days prior to the date the notice of redemption is to be given (or such shorter time as may be acceptable to the Trustee), an
Officer’s Certificate requesting that the Trustee give such notice together with the notice of redemption setting forth the information to be stated in such notice as provided in the preceding paragraph. 

  
 3 

 Provisions of this Indenture that apply to Notes called for redemption or
purchase also apply to portions of Notes called for redemption or purchase. On and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption.” 

(c) Amendment to Section 3.07(d). Section 3.07(d) of Article 3 of the Indenture is hereby amended by deleting the
section in its entirety and replacing such Section 3.07(d) with the following:

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes
or portions thereof called for redemption on the applicable Redemption Date.” 
 (d) Amendment of Article 4.
Subject to Section 2.01 hereof, the Indenture is hereby amended by deleting the following Sections of Article 4 of the Indenture and all references thereto: 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.17, 4.20 and

MISCELLANEOUS

 6

validly withdrawn) pursuant to the Offer on the Settlement Date following the Early Tender Deadline (such date of payment, the “Payment Date”). The Company shall provide written notice to the Trustee of the occurrence of the Payment

 Section 2.05 Successors. All agreements of the Company in the Indenture, as
amended by this Supplemental Indenture, and the Notes shall bind its successors. All agreements of the Trustee in the Indenture, as amended by this Supplemental Indenture, shall bind its successors. All agreements of each Guarantor in the Indenture
and Note Guarantees, as supplemented by this Supplemental Indenture, shall bind its successors, except as otherwise provided in Section 11.06 of the Indenture. 

Section 2.06 Severability. In case any provision in the Indenture, as amended by this Supplemental Indenture, or in the Notes is
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

Section 2.07 Counterpart Originals. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy
shall be an original, but all of them together represent the same agreement. Signatures of the parties hereto transmitted by facsimile or PDF may be used in lieu of the originals and shall be deemed to be their original signatures for all purposes.

 Section 2.08 Headings. The headings of the Articles and Sections of this Supplemental Indenture have been inserted for
convenience of reference only, are not to be considered a part of this Supplemental Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

adequacy of this Supplemental Indenture, and it shall not be responsible for any statement or recital herein or any other document pursuant to this Supplemental Indenture. The recitals contained herein shall be taken as the statements of the Company
and the Guarantors, and the Trustee assumes no responsibility for their correctness, and the Trustee makes no representation as to the validity or sufficiency of the Consent Solicitation, the Offer to Purchase, the Proposed Amendments, the Offer or
any other document used in connection with the Consent Solicitation, the Offer to Purchase, the Proposed Amendments, the Offer, this Supplemental Indenture or any consents thereto. This Supplemental Indenture is executed and accepted by the Trustee
subject to all the terms and 

  
 7 

 
conditions set forth in the Indenture with the same force and effect as if those terms and conditions were repeated at length herein and made applicable to the Trustee with respect hereto. In
entering into this Supplemental Indenture, the Trustee shall be entitled to the benefit of every provision of the Indenture relating to the conduct or affecting the liability or affording protection to the Trustee, whether or not elsewhere herein so
provided. The Company hereby confirms to the Trustee that this Supplemental Indenture has not resulted in a material modification of the Notes for Foreign Account Tax Compliance Act (“FATCA”) purposes.
