Company’s Board of Directors then in office; or

(either in one transaction or a series of related transactions) all or substantially all of its assets to, or merges or consolidates with, a Person other than (x) a Restricted Subsidiary of the Company or (y) a Successor Entity in which a

Notes substantially in the form attached as Exhibit A hereto, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee as custodian for the Depositary, and registered in the name of the
Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. 
 Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time
endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions and transfers of interests. Any endorsement of a Global Note to
reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as
required by Section 2.6 hereof. 
 Except as set forth in Section 2.6 hereof, the Global
Notes may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee. 
 (b) The Initial Notes are being issued by the Company only (i) to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act (“Rule 144A”))
(“QIBs”) and (ii) in reliance on Regulation S under the Securities Act (“Regulation S”). After such initial offers, Initial Notes that are Transfer Restricted Notes may be transferred to QIBs, in
reliance on Rule 144A or outside the United States pursuant to Regulation S or to the Company, in accordance with certain transfer restrictions. Initial Notes that are offered in reliance on Rule 144A shall be issued in the form of one or more
permanent Global Notes substantially in the form set forth in Exhibit A (the “QIB Global Note”) deposited with the Trustee, as Note Custodian, duly executed by the Company and authenticated by the Trustee as hereinafter
provided. Initial Notes that are offered in offshore transactions in reliance on Regulation S shall be issued in the form of one or more temporary Global Notes substantially in the form set forth in Exhibit A, including the
Regulation S Temporary Global Note Legend (the “Regulation S Temporary Global Note”) deposited with the Trustee, as Note Custodian, duly executed by the Company and authenticated by the Trustee as hereinafter provided.
Reasonably promptly following the date that is 40 days after the later of the commencement of the offering of the Notes in reliance on Regulation S and the Issue Date, a single permanent global Note in registered form substantially in the form of
Exhibit A (the “Regulation S Permanent Global Note,” and together with the Regulation S Temporary Global Note, the “Regulation S Global Note”) duly executed by the Company and
authenticated by the Trustee as hereinafter provided shall be deposited with the Trustee, as Note Custodian for the Depositary, and the Registrar shall reflect on its books and records the cancellation of the Regulation S Temporary Global Note and
the issuance of the Regulation S Permanent Global Note. The QIB Global Note and the Regulation S Global Note shall each be issued with separate CUSIP numbers. The aggregate principal amount of each Global Note may from time to time be increased
or decreased by adjustments made on the records of the 

  
 -30-

 
Trustee, as Note Custodian. Transfers of Notes between QIBs and to or by purchasers pursuant to Regulation S shall be represented by appropriate increases and decreases to the respective
amounts of the appropriate Global Notes, as more fully provided in Section 2.16. 
 (c)
Section 2.1(b) shall apply only to Global Notes deposited with or on behalf of the Depositary. 
 The
Company shall execute and the Trustee shall, in accordance with Section 2.1(b) and this Section 2.1(c), authenticate and deliver the Global Notes that (i) shall be registered in the name of the Depositary or the nominee
of the Depositary and (ii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions or held by the Trustee as Note Custodian for the Depositary. 

Participants shall have no rights either under this Indenture with respect to any Global Note held on their behalf by the
Depositary or by the Note Custodian as custodian for the Depositary or under such Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for
all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any Agent or other agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices of such Depositary governing the exercise of the rights of an owner of a beneficial interest in any Global Note. 

The Trustee shall have no responsibility or obligation to any Holder that is a member of (or a participant in) DTC or any
other Person with respect to the accuracy of the records of DTC (or its nominee) or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery of any notice (including any notice of
redemption) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to the Notes. The Trustee may rely (and shall be fully protected in relying) upon information furnished by DTC with respect to
its members, participants and any beneficial owners in the Notes. 
 (d) Notes issued in certificated form shall
be substantially in the form of Exhibit A attached hereto (but without including the text referred to in footnote 1 thereto). 
 SECTION 2.2 Execution and Authentication. 
 An Officer shall 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 shall nevertheless be valid. 

  
 -31-

 A Note shall not be valid until authenticated by the manual signature of a Responsible
Officer of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

The Trustee shall, upon a written order of the Company signed by one Officer directing the Trustee to authenticate the Notes and
certifying that all conditions precedent to the issuance of the Notes contained herein have been complied with, authenticate Notes for original issue (i) in an aggregate principal amount up to $300,000,000 on the date of this Indenture and
(ii) Additional Notes from time to time in compliance with Section 4.9. 
 The Trustee may appoint an
authenticating agent reasonably acceptable to the Company to authenticate Notes. Any such appointment shall be evidenced by an instrument signed by a Responsible Officer, a copy of which shall be furnished to the Company. Unless limited by the terms
of such appointment, 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 the Company or an Affiliate of the Company. 
 SECTION 2.3 Registrar; Paying Agent.

 The Company shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for
exchange (“Registrar”) and (ii) an office or agency where Notes may be presented for payment to a Paying Agent. The Registrar shall keep a register of the Notes and of their transfer and exchange. At the option of the Company,
payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders. 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 or any of its Subsidiaries may act as Paying Agent
or Registrar. 
 The Company shall notify the Trustee and the Trustee shall notify the Holders of the name and address of any
Agent not a party to this Indenture. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which shall incorporate the provisions of the TIA. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company shall notify the Trustee in writing of the name and address of any such Agent. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, or fails to give the foregoing
notice, the Trustee shall act as such, and shall be entitled to appropriate compensation in accordance with Section 7.7 hereof. 
 The Company initially appoints the Trustee to act as the Registrar and Paying Agent. 
 The Company initially appoints DTC to act as the Depositary with respect to the Global Notes. 

  
 -32-

 SECTION 2.4 Paying Agent to Hold Money in Trust. 

The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the
benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and shall 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) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it
as Paying Agent. Upon the occurrence of events specified in Section 6.1(7) hereof, the Trustee shall serve as Paying Agent for the Notes. 
 SECTION 2.5 Holder Lists. 
 The Trustee shall preserve in as current a form
as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at
least five (5) Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the
Holders, including the aggregate principal amount of the Notes held by each Holder thereof, and the Company shall otherwise comply with TIA § 312(a). 
 SECTION 2.6 Book-Entry Provisions for Global Securities. 
 (a) Each Global
Note shall (i) be registered in the name of the Depositary for such Global Notes or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear legends as required by
Section 2.6(e). 
 Members of, or participants in, the Depositary (“Agent Members”) shall have no
rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company
or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 

(b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its
successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with Section 2.16 and the rules and procedures of the Depositary. In addition, Certificated Notes shall be
transferred to all beneficial owners (or the requesting beneficial owners, in the case of clause (ii)) in exchange for their beneficial interests only if (i) the Depositary notifies the Company that it is unwilling or

  
 -33-

 
unable to continue as Depositary for the Global Notes or the Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not appointed by
the Company within ninety (90) days of such notice or (ii) an Event of Default of which a Responsible Officer of the Trustee has actual notice has occurred and is continuing and the Registrar has received a request from any beneficial
owner of an interest in the Global Note (subject to the fourth paragraph of Section 2.1(c) hereof) to issue such Certificated Notes. 
 (c) In connection with the transfer of the entire Global Note to beneficial owners pursuant to clause (b) of this Section, such Global Note shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Note an equal aggregate principal amount of
Certificated Notes of authorized denominations. 
 (d) The registered holder of a Global Note may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold interest through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. 

(e) Each Global Note shall bear the Global Note Legend on the face thereof. 

(f) At such time as all beneficial interests in Global Notes have been exchanged for Certificated Notes, redeemed, repurchased or
cancelled, all Global Notes shall be returned to or retained and cancelled 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
Certificated Notes, redeemed, repurchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the
direction of the Trustee, to reflect such reduction. 
 (g) General Provisions Relating to Transfers and Exchanges.

 (1) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global
Notes and Certificated Notes at the Registrar’s request. 
 (2) No service charge shall be made to a Holder for any
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar
governmental charge payable upon exchange or transfer pursuant to Sections 2.2, 2.10, 3.7, 4.10, 4.14 and 9.5 hereof). 
 (3) All Global Notes and Certificated Notes issued upon any registration of transfer or exchange of Global Notes or Certificated Notes shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Global Notes or Certificated Notes surrendered upon such registration of transfer or exchange. 

  
 -34-

 (4) The Registrar shall not be required (A) to issue, to register the transfer of or to
exchange Notes during a period beginning at the opening of fifteen (15) days before the day of any selection of Notes for redemption under Section 3.2 hereof and ending at the close of business on the day of selection, (B) to
register the transfer of or to exchange any Note so 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. 
 (5) 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 neither the Trustee, any Agent nor the Company shall be affected by notice to the contrary. 
 (6) The Trustee shall
authenticate Global Notes and Certificated Notes in accordance with the provisions of Section 2.2 hereof. Except as provided in Section 2.6(b), neither the Trustee nor the Registrar shall authenticate or deliver any
Certificated Note in exchange for a Global Note. 
 (7) Each Holder agrees to provide reasonable indemnity to the Company and
the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture or applicable United States federal or state securities law. 

(8) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners of interests in any Global Note) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with
the express requirements hereof. 
 SECTION 2.7 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon the written order of the Company signed by an Officer of the Company, shall authenticate a replacement Note if the Trustee’s requirements are met. 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 Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company and the Trustee may charge for their expenses in replacing a Note. 
 Every replacement Note is an
additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 

  
 -35-

 SECTION 2.8 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled 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 2.8 as not outstanding. Except as set forth in
Section 2.9 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser
for value. 
 If the principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be
outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a Subsidiary 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 shall be deemed to be no longer outstanding and shall cease to accrue interest. 

SECTION 2.9 Treasury Notes. 
 In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or by any Affiliate of the Company
shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes shown on the register as being owned shall be so
disregarded. Notwithstanding the foregoing, Notes that are to be acquired by the Company or an Affiliate of the Company pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title
to such Notes passes to such entity. 
 SECTION 2.10 Temporary Notes. 

Until Certificated Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes upon a
written order of the Company signed by an Officer of the Company. Temporary Notes shall be substantially in the form of Certificated Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable
delay, the Company shall prepare and the Trustee shall upon receipt of a written order of the Company signed by an Officer authenticate Certificated Notes in exchange for temporary Notes. 

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 

  
 -36-

 SECTION 2.11 Cancellation. 

The Company at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which
the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other than the
Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. The Trustee shall maintain a record of all cancelled Notes and
shall provide the Company a list of all cancelled Notes from time to time as requested by the Company. Subject to Section 2.7 hereof, the Company may not issue new Notes to replace Notes that it has redeemed or paid or that have been
delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice, and certification of their disposal delivered to the Company. 

SECTION 2.12 Defaulted Interest. 
 If the Company defaults in a payment of interest on the Notes, it shall 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, which date shall be at the earliest practicable date but in all events at least five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in
Section 4.1 hereof. The Company shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least fifteen (15) days before the special record
date, the Company (or the Trustee, in the name and at the expense of the Company) shall mail or cause to be mailed 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 Record Date. 
 Unless otherwise set forth in this Indenture, the record date for purposes of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under
this Indenture shall be determined as provided for in TIA § 316 (c). 
 SECTION 2.14 Computation of Interest.

 Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 

SECTION 2.15 CUSIP Number. 
 The Company in issuing the Notes may use a “CUSIP” number, and if it does so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders;
provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers
printed on the Notes. The Company shall promptly notify the Trustee of any change in the CUSIP number. 

  
 -37-

 SECTION 2.16 Special Transfer Provisions. 

Unless and until a Transfer Restricted Note is transferred or exchanged pursuant to an exemption under the Securities Act or under an
effective registration statement under the Securities Act, the following provisions shall apply: 
 (a)
Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Transfer Restricted Note (other than pursuant to Regulation S): 

(i) The Registrar shall register the transfer of a Transfer Restricted Note by a Holder to a QIB if such transfer is being
made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit A-2
hereto. 
 (ii) If the proposed transferee is an Agent Member and the Transfer Restricted Note to be transferred
consists of an interest in the Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph (i) above and (y) instructions given in accordance with the Depositary’s and the Registrar’s
procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the QIB Global Note in an amount equal to the principal amount of the beneficial interest in the Regulation S
Global Note to be so transferred, and the Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of such Regulation S Global Note. 

(b) Transfers Pursuant to Regulation S. The following provisions shall apply with respect to registration of
any proposed transfer of a Transfer Restricted Note pursuant to Regulation S: 
 (i) The Registrar shall
register any proposed transfer of a Transfer Restricted Note pursuant to Regulation S by a Holder upon receipt of (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially
in the form set forth in Exhibit A-3 hereto from the proposed transferor. 
 (ii) If the proposed
transferee is an Agent Member holding a beneficial interest in a QIB Global Note and the Transfer Restricted Note to be transferred consists of an interest in a QIB Global Note, upon receipt by the Registrar of (x) the letter, if any, required
by paragraph (i) above and (y) instructions in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the
Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in the QIB Global Note to be transferred, and the Registrar shall reflect on its books and records the date and an appropriate decrease in the
principal amount of the QIB Global Note. 

  
 -38-

 (c) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with the
Registration Rights Agreement, the Company shall issue and, upon receipt of an authentication order in accordance with Section 2.2, the Trustee shall authenticate one or more Global Notes not bearing the Restricted Notes Legend in an aggregate
principal amount equal to the principal amount of the beneficial interests in the Global Notes that are Transfer Restricted Notes tendered for acceptance in accordance with the Exchange Offer and accepted for exchange in the Exchange Offer.

 Concurrently with the issuance of such Global Notes, the Registrar shall cause the aggregate principal amount of the
applicable Transfer Restricted Notes to be reduced accordingly, and the Registrar shall deliver to the Persons designated by the Holders of Transfer Restricted Notes so accepted Global Notes not bearing the Restricted Notes Legend in the appropriate
principal amount. 
 (d) Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not
bearing the Restricted Notes Legend, the Registrar shall deliver Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, the Registrar shall deliver only Notes that
bear the Restricted Notes Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in
order to maintain compliance with the provisions of the Securities Act. 
 (e) General. By its acceptance
of any Note bearing the Restricted Notes Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend and agrees that it shall transfer such Note only as
provided in this Indenture. A transfer of a beneficial interest in a Global Note that does not involve an exchange of such interest for a Certificated Note or a beneficial interest in another Global Note shall be subject to compliance with
applicable law and the applicable procedures of the Depositary, but is not subject to any procedure required by this Indenture. 

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this
Section 2.16. 
 SECTION 2.17 Issuance of Additional Notes. 

The Company shall be entitled to issue Additional Notes under this Indenture in substantially the form of Exhibit A hereto that
shall have identical terms as the Initial Notes, other than with respect to the date of issuance, issue price and amount of interest payable on the first interest payment date applicable thereto (and, if such Additional Notes shall be Exchange
Notes, other than with respect to transfer restrictions, any Registration Rights Agreement and additional interest with respect thereto); provided that such issuance is not prohibited by the terms of this Indenture, including
Section 4.9. The Initial Notes and any Additional Notes and all Exchange Notes shall be treated as a single class for all purposes under this Indenture. 

  
 -39-

 With respect to any Additional Notes, the Company shall set forth in a resolution of its
Board of Directors and in an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information: 
 (1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 

(2) the issue price, the issue date, the CUSIP number, if any, of such Additional Notes, the first interest payment date
and the amount of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue; and 
 (3) whether such Additional Notes shall be Transfer Restricted Notes. 
 ARTICLE III

 REDEMPTION AND PREPAYMENT 
 SECTION 3.1 Notices to Trustee. 
 If the Company elects to redeem Notes
pursuant to the optional redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at least forty (40) days (or such shorter period as is acceptable to the Trustee) before a redemption date, an Officers’
Certificate setting forth (i) the section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the Redemption Price. 

If the Company is required to make an Offer to Purchase pursuant to Section 4.10 or 4.14 hereof, it shall furnish to
the Trustee, at least forty (40) days (or such shorter period as is acceptable to the Trustee) before the scheduled purchase date, an Officers’ Certificate setting forth (i) the section of this Indenture pursuant to which the offer to
purchase shall occur, (ii) the terms of the offer, (iii) the principal amount of Notes to be purchased, (iv) the purchase price and (v) the purchase date and further setting forth a statement to the effect that (a) the
Company or one of its Subsidiaries has effected an Asset Sale and there are Excess Proceeds aggregating more than $50.0 million or (b) a Change of Control has occurred or is scheduled to occur, as applicable. 

The Company will also provide the Trustee with any additional information that the Trustee reasonably requests in connection with any
redemption or offer. 
 SECTION 3.2 Selection of Notes to Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes or portions thereof to be redeemed among
the Holders in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate (and in a manner that complies with applicable legal requirements); provided that no Notes of $2,000 or less shall be redeemed in part. 

  
 -40-

 Notices of redemption shall be mailed by first class mail 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. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof
to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial
interests in a Global Note will be made, as appropriate). 
 On and after the redemption date, interest will cease to accrue on
Notes or portions of them called for redemption. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the
applicable Redemption Price pursuant to this Indenture and shall promptly notify the Company in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to $2,000 or any integral multiples of $1,000 in
excess thereof) of the principal of the Notes that have denominations larger than $2,000. 
 SECTION 3.3 Notice of
Redemption. 
 Subject to the provisions of Section 3.9, at least 30 days but not more than 60 days before a
redemption date, the Company shall mail or cause to be mailed by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed. 
 The notice shall identify the Notes to be redeemed and shall state: 

(1) the redemption date; 
 (2) the Redemption Price; 
 (3) if any Note is being redeemed in
part, the portion of the principal amount of such Notes 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 shall be issued upon cancellation of the
original Note; 
 (4) the name, telephone number 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, if any, 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; and 
 (8) that no representation
is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 

  
 -41-

 At the Company’s request, the Trustee shall give the notice of redemption in the
Company’s name and at the Company’s expense; provided, however, that the Company shall have delivered to the Trustee, at least 40 days prior to the redemption date (or such shorter period as is acceptable to the Trustee), an
Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notice as provided in the preceding paragraph. The notice mailed in the manner herein provided shall be conclusively
presumed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the
redemption of any other Note. 
 SECTION 3.4 Effect of Notice of Redemption. 

Once notice of redemption is mailed in accordance with Section 3.3 hereof, Notes called for redemption become irrevocably due
and payable on the redemption date at the Redemption Price plus accrued and unpaid interest, if any, to such date. A notice of redemption may not be conditional. 
 SECTION 3.5 Deposit of Redemption Price or Purchase Price. 
 On or before
10:00 a.m. (New York City time) on each redemption date or the date on which Notes must be accepted for purchase pursuant to Section 4.10 or 4.14, the Company shall deposit with the Trustee or with the Paying Agent (other than the
Company or an Affiliate of the Company) money sufficient to pay the Redemption Price or Purchase Price of and accrued and unpaid interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall 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 Price or Purchase Price of (including any applicable premium), and accrued interest, if any, on,
all Notes to be redeemed or purchased. 
 If Notes called for redemption or tendered in an Offer are paid or if the Company has
deposited with the Trustee or Paying Agent money sufficient to pay the Redemption Price or Purchase Price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption date or purchase date, as
applicable, interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered pursuant to an Offer and not withdrawn (regardless of whether certificates for such securities are actually surrendered). 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, if any, 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 shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid
principal from the redemption date 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 4.1 hereof.

certificate, that, to the best of his or her knowledge, each entity has kept, observed, performed and fulfilled in all material respects each and every covenant contained in this Indenture and is not in default in the performance or observance of

required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments under this Indenture or the Notes.

expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of
every such power as though no such law has been enacted.

 SECTION 4.7 Limitation on Restricted Payments. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment

Default shall have occurred and be continuing or will occur as a consequence thereof; 
 (b) after giving effect
to such Restricted Payment on a pro forma basis, the Company would be permitted to Incur at least $1.00 of additional Debt (other than Permitted Debt) pursuant to the provisions described in the first paragraph under Section 4.9;

expended or declared for all Restricted Payments made on or after the Issue Date (excluding Restricted Payments permitted by clauses (ii), (iii) and (vi)) of the next succeeding paragraph) shall not exceed the sum (without duplication) of:

 (1) 50% of the Consolidated Net Income (or, if Consolidated Net Income shall be a deficit, minus 100% of such
deficit) of the Company accrued on a cumulative basis during the period (taken as one accounting period) beginning on March 1, 2007 and ending on the last day of the fiscal quarter immediately preceding the date of such proposed Restricted
Payment, plus 
 (2) 100% of the net proceeds received by the Company (including the Fair Market Value of
property other than cash) subsequent to June 12, 2007 either (i) as a contribution to its common equity capital or (ii) from the issuance and sale (other than to a Restricted Subsidiary) of its Qualified Capital Stock, including

Subsidiary of the Company), plus 
 (3) 100% of the net reduction in Investments made subsequent to
June 12, 2007 (other than Permitted Investments), in any Person, resulting from payments of interest on Debt, dividends, repayments of loans or advances (but only to the extent such interest, dividends or repayments are not included in the
calculation of Consolidated Net Income), in each case to the Company or any Restricted Subsidiary from any Person (including, without limitation, from Unrestricted Subsidiaries) or from redesignations of Unrestricted Subsidiaries as Restricted
Subsidiaries in accordance with this Indenture, not to exceed in the case of any Person the amount of Investments previously made by the Company or any Restricted Subsidiary in such Person. 

Notwithstanding the foregoing provisions, the Company and its Restricted Subsidiaries may take the following actions; provided
that, in the case of clauses (iv), (v), (viii) or (ix), immediately after giving effect to such action, no Default or Event of Default has occurred and is continuing: 

(i) the payment of any dividend on Capital Stock in the Company or a Restricted Subsidiary within 60 days after
declaration thereof if at the declaration date such payment would not have been prohibited by the foregoing provisions of this Section 4.7; 

  
 -48-

 (ii) the repurchase, redemption, retirement or other acquisition for value
of any Qualified Capital Stock of the Company by conversion into, or by or in exchange for, Qualified Capital Stock, or out of net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of other Qualified
Capital Stock of the Company; or the making of any Restricted Payment out of net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of Qualified Capital Stock of the Company; provided that the amount of
any such net cash proceeds that are used for such repurchase, redemption, retirement or other acquisition for value shall be excluded from clause (c)(2) of the preceding paragraph; 

(iii) the redemption, defeasance, repurchase, retirement or other acquisition for value of any Debt of the Company that is
subordinate in right of payment to the Notes out of the net cash proceeds of a substantially concurrent issue and sale (other than to a Subsidiary of the Company) of (x) new subordinated Debt of the Company Incurred in accordance with this
Indenture or (y) Qualified Capital Stock of the Company; provided that the amount of any such net cash proceeds that are used for such redemption, defeasance, repurchase, retirement or other acquisition for value shall be excluded from
clause (c)(2) of the preceding paragraph;

Restricted Subsidiary of the Company to the holders of any class of its Capital Stock on a pro rata basis; provided that the Company and its Restricted Subsidiaries own at least a majority of the outstanding shares of such class of

(ix) other Restricted Payments in an aggregate amount not to exceed 7.5% of Total Assets. 

If the Company makes a Restricted Payment which, at the time of the making of such Restricted Payment, in the good faith determination of the Company,
would be permitted under the requirements of this Indenture, such Restricted Payment shall be deemed to have been made in compliance with this Indenture notwithstanding any subsequent adjustment made in good faith to the Company’s financial
statements affecting Consolidated Net Income. 
 If any Person in which an Investment is made, which Investment constitutes a
Restricted Payment when made, thereafter becomes a Restricted Subsidiary in accordance with this Indenture, all such Investments previously made in such Person shall no longer be counted as Restricted Payments for purposes of calculating the
aggregate amount of Restricted Payments pursuant to clause (c) of the first paragraph under this Section 4.7, in each case to the extent such Investments would otherwise be so counted. 

If the Company or a Restricted Subsidiary transfers, conveys, sells, leases or otherwise disposes of an Investment in accordance with
Section 4.10, which Investment was originally included in the aggregate amount expended or declared for all Restricted Payments pursuant to clause (c) of the definition of “Restricted Payments,” the aggregate amount
expended or declared for all Restricted Payments shall be reduced by the lesser of (i) the Net Cash Proceeds from the transfer, conveyance, sale, lease or other disposition of such Investment or (ii) the amount of the original Investment,
in each case, to the extent originally included in the aggregate amount expended or declared for all Restricted Payments pursuant to clause (c) of the definition of “Restricted Payments.” 

For purposes of this Section 4.7, if a particular Restricted Payment involves a non-cash payment, including a distribution of
assets, then such Restricted Payment shall be deemed to be in an amount equal to the cash portion of such Restricted Payment, if any, plus an amount equal to the Fair Market Value of the non-cash portion of such Restricted Payment. 

SECTION 4.8 Limitation on Dividends and Other Payments Affecting Restricted Subsidiaries. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, cause or suffer to exist or
become effective or enter into any encumbrance or restriction (other than pursuant to this Indenture, law, or regulation) on the ability of any Restricted Subsidiary to (i) pay dividends or make any other distributions on its Capital Stock
owned by the Company or any Restricted Subsidiary or pay any Debt or other obligation owed to the Company or any Restricted Subsidiary, (ii) make loans or advances to the Company or any Restricted Subsidiary thereof or (iii) transfer any
of its property or assets to the Company or any Restricted Subsidiary.

 However, the preceding restrictions will not apply to the following encumbrances or
restrictions existing under or by reason of: 
 (a) any encumbrance or restriction in existence on the Issue
Date, including those required by the Credit Agreement and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that the amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to such dividend or other payment restrictions than those contained in these agreements on the Issue
Date; 
 (b) any encumbrance or restriction pursuant to an agreement relating to an acquisition of property, so
long as the encumbrances or restrictions in any such agreement relate solely to the property so acquired (and are not or were not created in anticipation of or in connection with the acquisition thereof); 

(c) any encumbrance or restriction which exists with respect to a Person that becomes a Restricted Subsidiary or merges
with or into a Restricted Subsidiary of the Company on or after the Issue Date, which is in existence at the time such Person becomes a Restricted Subsidiary, but not created in connection with or in anticipation of such Person becoming a Restricted
Subsidiary, and which is not applicable to any Person or the property or assets of any Person other than such Person or the property or assets of such Person becoming a Restricted Subsidiary; 

(d) any encumbrance or restriction pursuant to an agreement effecting a permitted renewal, refunding, replacement,
refinancing or extension of Debt issued pursuant to an agreement containing any encumbrance or restriction referred to in the foregoing clauses (a) through (c), so long as the encumbrances and restrictions contained in any such refinancing
agreement are no less favorable in any material respect to the Holders than the encumbrances and restrictions contained in the agreements governing the Debt being renewed, refunded, replaced, refinanced or extended in the good faith judgment of the
Company; 
 (e) customary provisions restricting subletting or assignment of any lease, contract, or license of
the Company or any Restricted Subsidiary or provisions in agreements that restrict the assignment of such agreement or any rights thereunder; 
 (f) any restriction on the sale or other disposition of assets or property securing Debt as a result of a Permitted Lien on such assets or property; 

(g) any encumbrance or restriction by reason of applicable law, rule, regulation or order; 

(h) any encumbrance or restriction under this Indenture, the Notes and the Note Guarantees; 

  
 -51-

 (i) any encumbrance or restriction under the sale of assets, including,
without limitation, any agreement for the sale or other disposition of a Subsidiary that restricts distributions by that Subsidiary pending its sale or other disposition; 

(j) restrictions on cash and other deposits or net worth imposed by customers under contracts entered into in the ordinary
course of business; 
 (k) provisions with respect to the disposition or distribution of assets or property in
joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business; 
 (l) any instrument governing Debt or Capital Stock of a Person acquired by the Company or any of the Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Debt or
Capital Stock was Incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of
the Person, so acquired; provided that, in the case of Debt, such Debt was permitted by the terms of this Indenture to be Incurred; 
 (m) purchase money obligations (including Capital Lease Obligations) for property acquired in the ordinary course of business that impose restrictions on that property so acquired of the nature described
in clause (iii) of the first paragraph hereof; and 
 (n) customary provisions contained in debt instruments
of non-Domestic Subsidiaries that are entered into for the purpose of funding working capital requirements. 
 Nothing contained
in this Section 4.8 shall prevent the Company or any Restricted Subsidiary from (i) creating, incurring, assuming or suffering to exist any Liens otherwise permitted by Section 4.12 or (ii) restricting the sale or
other disposition of property or assets of the Company or any of its Restricted Subsidiaries that secure Debt of the Company or any of its Restricted Subsidiaries Incurred in accordance with this Indenture. 

SECTION 4.9 Limitation on Incurrence of Debt. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, Incur any Debt (including Acquired Debt); provided, the Company and the Guarantors may Incur Debt so long as,
immediately after giving effect to the Incurrence of such Debt and the receipt and application of the proceeds therefrom, (a) the Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries, determined on a pro forma
basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four Quarter Period (other than any Debt Incurred under the revolving portion of a credit agreement), had
been Incurred and the proceeds thereof had been applied at the beginning of the Four Quarter Period, and any other Debt repaid since the beginning of the Four Quarter Period had been repaid at the beginning of the Four Quarter Period, would be
greater than 2.00:1 and (b) no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the Incurrence of such Debt. 

  
 -52-

 If, during the Four Quarter Period or subsequent thereto and prior to the date of
determination, the Company or any of its Restricted Subsidiaries shall have engaged in any Asset Sale or Asset Acquisition or shall have designated any Restricted Subsidiary to be an Unrestricted Subsidiary or any Unrestricted Subsidiary to be a
Restricted Subsidiary, Consolidated Cash Flow Available for Fixed Charges and Consolidated Interest Expense for the Four Quarter Period shall be calculated on a pro forma basis giving effect to such Asset Sale or Asset Acquisition or designation, as
the case may be, and the application of any proceeds therefrom as if such Asset Sale or Asset Acquisition or designation had occurred on the first day of the Four Quarter Period. 

If the Debt which is the subject of a determination under this provision is Acquired Debt, or Debt Incurred in connection with the
simultaneous acquisition of any Person, business, property or assets, or Debt of an Unrestricted Subsidiary being designated as a Restricted Subsidiary, then such ratio shall be determined by giving effect (on a pro forma basis, as if the
transaction had occurred at the beginning of the Four Quarter Period) to the Incurrence of such Acquired Debt or such other Debt by the Company or any of its Restricted Subsidiaries and the inclusion, in Consolidated Cash Flow Available for Fixed
Charges, of the Consolidated Cash Flow Available for Fixed Charges of the acquired Person, business, property or assets or redesignated Subsidiary. 
 Notwithstanding the first paragraph above, the Company and its Restricted Subsidiaries may Incur Permitted Debt. 
 For purposes of determining any particular amount of Debt under this Section 4.9, Guarantees or obligations with respect to letters of credit supporting Debt otherwise included in the
determination of such particular amount shall not be included. For the purposes of determining compliance with this Section 4.9, in the event that an item of Debt meets the criteria of more than one of the types of Debt described above,
including categories of Permitted Debt and under part (a) in the first paragraph of this Section 4.9, the Company, in its sole discretion, may classify, and from time to time may reclassify, all or any portion of such item of Debt;
provided, however, that Debt outstanding on the Issue Date under the Credit Agreement shall always be deemed Incurred under clause (i) of the definition of Permitted Debt. 

The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of
additional Debt or payment of dividends on Capital Stock in the forms of additional shares of Capital Stock with the same terms will not be deemed to be an Incurrence of Debt or issuance of Capital Stock for purposes of this Section 4.9.

 SECTION 4.10 Limitation on Asset Sales. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Capital Stock issued or
sold or otherwise disposed of; and 

  
 -53-

 (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. For purposes of this provision, each of the following will be deemed to be cash: 
 (a) any liabilities, as shown on the most recent consolidated balance sheet of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms
subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary assignment and assumption agreement that releases the Company or such Restricted Subsidiary from further liability;

 (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 within 365 days of their receipt to the extent of the cash received in that conversion; and 

(c) any Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having
an aggregate fair market value (as determined in good faith by the Company), taken together with all other Designated Non-cash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed 10.0% of Total
Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

 Within 540 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Company (or the applicable Restricted
Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option: 
 (1) to permanently repay or
prepay Debt outstanding under the Credit Agreement and, if the Debt repaid is revolving credit Debt, to correspondingly reduce commitments with respect thereto; 
 (2) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business; 
 (3) to make capital expenditures or to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business; or 

(4) any combination of the foregoing. 

  
 -54-

 Any Net Cash Proceeds from Asset Sales that are not applied or invested as provided in the
preceding paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $50.0 million, within thirty days thereof, the Company will make an Offer to Purchase
to all Holders of Notes and if applicable, Pari Passu Indebtedness (on a pro rata basis, if applicable) equal to the Excess Proceeds. The offer price in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid
interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Offer to Purchase, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the
aggregate principal amount of Notes and Additional Notes tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such Additional Notes to be purchased on a pro rata basis. Upon completion of
each Offer to Purchase, the amount of Excess Proceeds will be reset at zero. 
 The Company will comply with the requirements of
any applicable securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Offer to Purchase. To the extent that the provisions of any securities laws
or regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this
Indenture by virtue of such compliance. 
 SECTION 4.11 Limitation on Transactions with Affiliates. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, conduct any business or enter
into or permit to exist any transaction or series of related transactions (including, but not limited to, the purchase, sale or exchange of property, the making of any Investment, the giving of any Guarantee or the rendering of any service) with any
Unrestricted Subsidiary or any Affiliate of the Company or any Restricted Subsidiary other than transactions solely among any of the Company and its Restricted Subsidiaries (an “Affiliate Transaction”), unless: 

(i) such business, transaction or series of related transactions is on terms no less favorable to the Company or such
Restricted Subsidiary than those that could be obtained in a comparable arm’s length transaction between unaffiliated parties; and 
 (ii) with respect to an Affiliate Transaction involving an amount or having a value in excess of $10.0 million the Company delivers to the Trustee an Officers’ Certificate stating that such
business, transaction or series of related transactions complies with clause (i) above. 
 In the case of an Affiliate
Transaction involving an amount or having a value in excess of $50.0 million, the Company must obtain a resolution of the Board of Directors certifying that such Affiliate Transaction complies with clause (i) above. 

  
 -55-

 The foregoing limitations do not limit, and shall not apply to: 

(1) Restricted Payments that are permitted by Section 4.7 hereof and Permitted Investments permitted under
this Indenture; 
 (2) the payment of reasonable and customary fees and indemnities to members of the Board of
Directors of the Company or a Restricted Subsidiary who are outside directors, 
 (3) the payment of reasonable
and customary compensation and other benefits (including retirement, health, option, deferred compensation and other benefit plans) and indemnities to officers and employees of the Company or any Restricted Subsidiary as determined by the Board of
Directors thereof in good faith, 
 (4) transactions between or among the Company and/or its Restricted
Subsidiaries; 
 (5) the issuance of Qualified Capital Stock of the Company otherwise permitted hereunder, and

 (6) transactions with respect to which the Company has obtained a written opinion of a nationally recognized
investment banking, accounting or appraisal firm stating that the transaction is fair to the Company or such Restricted Subsidiary from a financial point of view. 
 SECTION 4.12 Limitation on Liens. 
 The Company will not, and will not
permit any of its Restricted Subsidiaries, directly or indirectly, to enter into, create, incur, assume or suffer to exist any Liens of any kind, other than Permitted Liens, on or with respect to any of its property or assets now owned or hereafter
acquired or any interest therein or any income or profits therefrom without securing the Notes and all other amounts due under this Indenture (for so long as such Lien exists) equally and ratably with (or prior to) the obligation or liability
secured by such Lien. 
 SECTION 4.13 [Reserved] 

SECTION 4.14 Offer to Purchase upon Change of Control. 
 Upon the occurrence of a Change of Control, the Company will make an Offer to Purchase (the “Change of Control Offer”) all of the outstanding Notes at a Purchase Price in cash equal to
101% of the principal amount tendered, together with accrued interest, if any, to but not including the Purchase Date (the “Change of Control Payment”). For purposes of the foregoing, an Offer to Purchase shall be deemed to have
been made if (i) within 30 days following the date of the consummation of a transaction or series of related transactions that constitutes a Change of Control, the Company commences an Offer to Purchase all outstanding Notes at the Purchase
Price and (ii) all Notes properly tendered and not withdrawn pursuant to the Offer to Purchase are purchased on the terms of such Offer to Purchase. The Company may commence an Offer to 

  
 -56-

 
Purchase in respect of a Change of Control prior to the consummation of such Change of Control if a definitive agreement for such Change of Control is in place at the time of such Offer to
Purchase. If the Offer to Purchase is commenced prior to the occurrence of the Change of Control, the Offer may be conditioned upon the occurrence of the Change of Control. 
 The Change of Control provisions described above will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control,
this Indenture does not contain provisions that permit the Holders to require that the Company repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction. 

The Company shall not be required to make a Change of Control Offer upon a Change of Control if (i) a third party makes such Change
of Control Offer contemporaneously with or upon a Change of Control in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Company and purchases all Notes
validly tendered and not withdrawn under such Change of Control Offer or (ii) a notice of redemption with respect to all outstanding Notes has been given pursuant to Section 3.7 hereof and the Company redeems all such Notes in
accordance with Article III. 
 The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Offer to Purchase following a Change of Control. To the extent that the provisions of
any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the
Change of Control provisions of this Indenture by virtue of such compliance. 
 SECTION 4.15 Corporate Existence.

 Subject to Section 4.14 and Article V hereof, as the case may be, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of the Guarantors in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company or any such Guarantor and the rights (charter and statutory) and material governmental licenses and franchises of the Company and the Guarantors; provided 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 the Guarantors, if the Board of Directors of the Company shall determine that the preservation thereof is no longer
necessary or desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders. 

  
 -57-

 SECTION 4.16 [Reserved]. 

SECTION 4.17 Additional Note Guarantees. 
 If any Domestic Subsidiary that is not a Guarantor guarantees any Debt of the Company under any Credit Facility in excess of $25.0 million, such Domestic Subsidiary (i) shall become a Guarantor and
execute a supplemental indenture and (ii) shall deliver an Opinion of Counsel reasonably satisfactory to the Trustee that such supplemental indenture has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes
an enforceable obligation of such Restricted Subsidiary, within 10 Business Days of the date on which it initially guarantees any Debt of the Company under any such Credit Facility. 

SECTION 4.18 Limitation on Creation of Unrestricted Subsidiaries. 

The Company may designate any Subsidiary of the Company to be an “Unrestricted Subsidiary” as provided below, in which event
such Subsidiary and each other Person that is then or thereafter becomes a Subsidiary of such Subsidiary will be deemed to be an Unrestricted Subsidiary. 
 The Company may designate any Subsidiary to be an Unrestricted Subsidiary unless such Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property of, any other Restricted Subsidiary of
the Company; provided that either: 
 (x) the Subsidiary to be so designated has total assets of $1,000 or
less; or 
 (y) immediately after giving effect to such designation, the Company could Incur at least $1.00 of
additional Debt (other than Permitted Debt) pursuant to the first paragraph under Section 4.9; and provided further that the Company could make a Restricted Payment in an amount equal to the greater of the Fair Market Value or
book value of such Subsidiary pursuant to Section 4.7 and such amount is thereafter treated as a Restricted Payment for the purpose of calculating the amount available for Restricted Payments thereunder. 

An Unrestricted Subsidiary may be designated as a Restricted Subsidiary if (i) all the Debt of such Unrestricted Subsidiary could be
Incurred pursuant to Section 4.9 and (ii) all the Liens on the property and assets of such Unrestricted Subsidiary could be incurred pursuant to Section 4.12. 

Any such designation of a Restricted Subsidiary as an Unrestricted Subsidiary or of an Unrestricted Subsidiary as a Restricted Subsidiary
shall be made by the Board of Directors of the Company, and a copy of the determination of the Board of Directors of the Company giving effect to such designation shall be promptly filed with the Trustee. 

SECTION 4.19 Termination of Covenants. 
 During any period of time after the Issue Date that: (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is continuing under this

  
 -58-

 
Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Termination Event”), then
Sections 4.7, 4.8, 4.9, 4.10, 4.11 and clauses (iii) and (iv) of the first paragraph of Section 5.1 (the “Terminated Covenants”) shall not be applicable to the Notes.

 In the event that a Termination Event occurs, the Company and the Restricted Subsidiaries will no longer be subject to the
Terminated Covenants under this Indenture, regardless of whether and on any subsequent date one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating.

 ARTICLE V 
 SUCCESSORS 
 SECTION 5.1 Consolidation, Merger, Conveyance, Transfer or
Lease. 
 The Company will not in any transaction or series of transactions, consolidate with or merge into any other Person
(other than a merger of a Restricted Subsidiary into the Company in which the Company is the continuing Person or the merger of a Restricted Subsidiary into or with another Restricted Subsidiary or another Person that as a result of such transaction
becomes or merges into a Restricted Subsidiary), or transfer all or substantially all of the assets of the Company and its Restricted Subsidiaries (determined on a consolidated basis), taken as a whole, to any other Person, unless: 

(i) either: (a) the Company shall be the continuing Person or (b) the Person (if other than the Company) formed
by such consolidation or into which the Company is merged, or the Person that acquires, by sale, assignment, conveyance, transfer, lease or disposition, all or substantially all of the property and assets of the Company (such Person, the
“Surviving Entity”), (1) shall be a corporation, organized and validly existing under the laws of the United States, any political subdivision thereof or any state thereof or the District of Columbia and (2) shall
expressly assume, by a supplemental indenture, the due and punctual payment of all amounts due in respect of the principal of (and premium, if any) and interest on all the Notes and the performance of the covenants and obligations of the Company
under this Indenture; 
 (ii) immediately before and immediately after giving effect to such transaction or
series of transactions on a pro forma basis (including, without limitation, any Debt Incurred or anticipated to be Incurred in connection with or in respect of such transaction or series of transactions), no Default or Event of Default shall have
occurred and be continuing or would result therefrom; 
 (iii) immediately after giving effect to any such
transaction or series of transactions on a pro forma basis (including, without limitation, any Debt Incurred or anticipated to be Incurred in connection with or in respect of such transaction or series of transactions) as if such transaction or
series of transactions had occurred on the first day 

  
 -59-

 
of the determination period, the Company (or the Surviving Entity if the Company is not continuing) could Incur $1.00 of additional Debt (other than Permitted Debt) under the first paragraph of
Section 4.9; and 
 (iv) the Company delivers, or causes to be delivered, to the Trustee, in form and
substance reasonably satisfactory to the Trustee, an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition complies with the
requirements of this Indenture. 
 The preceding clause (iii) will not prohibit a merger between the Company and a
Restricted Subsidiary that is a wholly owned Subsidiary of the Company, so long as the amount of Debt of the Company and its Restricted Subsidiaries is not increased thereby. 
 For all purposes of this Indenture and the Notes, Subsidiaries of any Surviving Entity will, upon such transaction or series of related transactions, become Restricted Subsidiaries or Unrestricted
Subsidiaries as provided pursuant to this Indenture and all Debt, and all Liens on property or assets, of the Surviving Entity and its Subsidiaries that was not Debt, or were not Liens on property or assets, of the Company and its Subsidiaries
immediately prior to such transaction or series of related transactions shall be deemed to have been Incurred upon such transaction or series of related transactions. 
 SECTION 5.2 Surviving Entity Substituted. 
 Upon any transaction or series
of transactions that are of the type described in, and are effected in accordance with, conditions described in Section 5.1, the Surviving Entity shall succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the Surviving Entity 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 Surviving Entity had been named as the Company therein; and when a Surviving Entity duly assumes all of the obligations and covenants of the Company pursuant to this Indenture and
the Notes, except in the case of a lease, the predecessor Person shall be relieved of all such obligations. 
 ARTICLE VI

 DEFAULTS AND REMEDIES 
 SECTION 6.1 Events of Default. 
 Each of the following constitutes an
“Event of Default”:

any, on) any Note at its maturity (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise); 

  
 -60-

 (2) default in the payment of any interest upon any Note when it becomes due
and payable, and continuance of such default for a period of 30 days;

(4) default in the performance, or breach, of any covenant or agreement of the Company or any Guarantor in this Indenture
(other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in clauses (1), (2) or (3) above), and continuance of such default or breach for a period of 60 days, or in the case of any
failure to comply with Section 4.3, 180 days, in each case, after written notice thereof has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the
outstanding Notes; 
 (5) a default or defaults under any bonds, debentures, notes or other evidences of Debt
(other than the Notes) by the Company or any Significant Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at least $30.0 million, whether such Debt now exists or shall hereafter be created, which
default or defaults shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or shall constitute a failure to pay at least $30.0 million of such Debt when due and payable after the expiration of any
applicable grace period with respect thereto, and such Debt, in either case, is not discharged or such acceleration shall not have been rescinded or annulled, within 30 days after notice thereof shall have been given, by registered mail, to the
Company by either the Trustee, or to the Company and the Trustee by the Holders of at least 25% of the outstanding principal amount of the Notes; 
 (6) the entry against the Company or any Significant Subsidiary of a final judgment or final judgments for the payment of money (except to the extent such judgment is covered by insurance and the
Company’s insurer has not denied coverage) in an aggregate amount in excess of $30.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60
consecutive days; or 
 (7) (i) the Company, any Significant Subsidiary or each member of any group of Restricted
Subsidiaries that, taken as a whole (and considered as a single entity), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 

(a) commences a voluntary case, 
 (b) consents to the entry of an order for relief against it in an involuntary case, 

  
 -61-

 (c) consents to the appointment of a Custodian of it or for all or
substantially all of its property, 
 (d) makes a general assignment for the benefit of its creditors, or

 (e) admits in writing its inability generally to pay its debts as the same become due; 

(ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

 (b) appoints a Custodian of the Company, any Significant Subsidiary or each member of any group of Restricted Subsidiaries that, taken together (and considered as a single entity), would constitute a
Significant Subsidiary or for all or substantially all of the property of the Company, any Significant Subsidiary or each member of any group of Restricted Subsidiaries that, taken together (and considered as a single entity), would constitute a
Significant Subsidiary; or 
 (c) orders the liquidation of the Company, any Significant Subsidiary or each
member of any group of Restricted Subsidiaries that, taken together (and considered as a single entity), would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 

SECTION 6.2 Acceleration. 
 If an Event of Default (other than an Event of Default specified in clause (7) of Section 6.1 with respect to the Company) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company
(and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may rescind and
annul such acceleration: 
 (1) if the rescission would not conflict with any judgment or decree; 

(2) if all existing Events of Default have been cured or waived except nonpayment of principal and interest that has
become due solely because of this acceleration; 
 (3) if the Company has paid to the Trustee its reasonable
compensation and reimbursed the Trustee of its expenses, disbursements and advances; and 

  
 -62-

 (4) in the event of a cure or waiver of an Event of Default of the type set
forth in Section 6.1(7), the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. 
 No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto. 
 In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) of Section 6.1 has occurred and is continuing, the declaration of
acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (5) of Section 6.1 shall be remedied or cured by the Company or a
Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not
conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes. 
 If an Event of Default specified in clause (7) of Section 6.1 occurs with respect to the Company, the principal of and any accrued interest on the Notes then outstanding shall ipso facto
become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
 SECTION 6.3
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, or 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 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. 

SECTION 6.4 Waiver of Past Defaults. 
 The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (other than as a result of an acceleration), which shall require the consent of all of
the Holders of the Notes then outstanding. 
 SECTION 6.5 Control by Majority. 

The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or 

  
 -63-

 
exercising any trust or power conferred on the Trustee. However, (i) 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 or that may involve the Trustee in personal liability, and (ii) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. In case an
Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of its own affairs. Notwithstanding any provision to the contrary in this Indenture, the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such
request or direction. 
 SECTION 6.6 Limitation on Suits. 

No Holder of any Note will have any right to institute any proceeding with respect to this Indenture or for any remedy hereunder, unless
such Holder shall have previously given to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request
and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note for enforcement of payment of the principal of (and premium, if any) or interest on such Note
on or after the respective due dates expressed in such Note. 
 SECTION 6.7 Rights of Holders of Notes to Receive
Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal,
premium, if any, and interest on or after the respective due dates expressed in the Note held by such Holder (including in connection with an Offer to Purchase), 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. 
 SECTION 6.8 Collection Suit by Trustee.

 If an Event of Default specified in Section 6.1(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 for the whole amount of principal of, premium, 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 reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel. 

  
 -64-

 SECTION 6.9 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 allowed in any judicial proceedings relative to the Company (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 securities or property payable or deliverable upon the conversion or exchange of the Notes or 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 7.7 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 7.7 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. 

SECTION 6.10 Priorities. 
 If the Trustee collects any money or property pursuant to this Article VI, 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 7.7 hereof, including payment of
all reasonable compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, 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 interest respectively; 
 Third: without duplication, to
the Holders for any other Obligations owing to the Holders under this Indenture and the Notes; and 
 Fourth: to
the Company 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 pursuant to this Section 6.10. 

  
 -65-

 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 and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a
suit by a Holder pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

 (a) In case an Event of Default shall occur (which shall not be cured), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill

accuracy of mathematical calculations or other facts stated therein). 
 However, the Trustee shall examine the certificates and opinions
furnished to it to determine whether or not they conform to the requirements of this Indenture.

 (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.1;

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 7.1. 

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be
under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holders shall have offered to the Trustee reasonable security and indemnity satisfactory to it against any loss, liability
or expense. 
 (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in
writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 SECTION 7.2 Rights of Trustee. 
 (a) The Trustee may conclusively rely and
shall be fully protected in acting or refraining from acting on any document (whether in original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or
matter stated in the document. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. Prior to taking, suffering or admitting any
action, the Trustee may consult with counsel of the Trustee’s own choosing, and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in conclusive reliance on
the advice or opinion of such counsel. 
 (c) The Trustee may act through its attorneys and agents and shall not be responsible
for the misconduct or negligence of any attorney or agent appointed with due care. 
 (d) The Trustee shall not be liable for
any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. Any request or direction of the Company mentioned herein shall be sufficiently evidenced by an
Officers’ Certificate and any resolution of the Board of Directors may be sufficiently evidenced by a board resolution of the Board of Directors of the Company. Whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon
an Officers’ Certificate. 

  
 -67-

 (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction
or notice from the Company or a Guarantor shall be sufficient if signed by an officer of the Company or such Guarantor. 
 (f)
The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity
satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 
 (g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit. 

(h) The rights, privileges, protections and benefits given to the Trustee, including, without limitation, its rights to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Persons employed to act hereunder. 
 (i) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions
pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not
superseded. 
 (j) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of
Default unless the Trustee shall have received from the Company or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 12.2 hereof, and such notice references the Notes and this
Indenture. In the absence of any such notice, the Trustee may conclusively assume that no such Default or Event of Default exists. 
 SECTION 7.3 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 it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as Trustee or resign. 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 7.4 Trustee’s Disclaimer. 

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company’s use of the 

  
 -68-

 
proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes, any statement or recital on any Officers’ Certificate delivered to the Trustee under
Article IV or Section 8.4 or 10.4 hereof, or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 

SECTION 7.5 Notice of Defaults. 
 If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer, the Trustee shall mail to Holders 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 interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a
trust committee of directors or Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interests of the Holders. 
 SECTION 7.6 Reports by Trustee to Holders of the Notes. 
 Within 60 days
after each November 15 beginning with November 15, 2012, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders 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 shall comply with TIA § 313(b). The Trustee shall also transmit by mail all
reports as required by TIA § 313(c). 
 A copy of each report at the time of its mailing to the Holders shall be
mailed to the Company and filed with the Commission and each stock exchange on which the Company has informed the Trustee in writing the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when
the Notes are listed on any stock exchange and of any delisting thereof. 
 SECTION 7.7 Compensation and Indemnity.

 The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and
services hereunder as agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall 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 shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

The Company and the Guarantors, jointly and severally, shall indemnify the Trustee (which for purposes of this Section 7.7
shall include its officers, directors, employees, agents and counsel) against any and all claims, damage, losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this
Indenture, 

  
 -69-

 
including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.7) and defending itself against any claim (whether asserted by the Company
or 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, claim, damage, liability or expense may be attributable to its negligence,
willful misconduct or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder except to the
extent such failure jeopardizes the Company’s ability to defend against such claim. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the
reasonable fees and expenses of one such counsel; provided that the Company shall not be required to pay such fees and expenses if it assumes the Trustee’s defense and, in the Trustee’s reasonable judgment, there is no conflict of
interest between the Company and the Trustee in connection with such defense. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 

The obligations of the Company and the Guarantors under this Section 7.7 shall survive the satisfaction and discharge of this
Indenture or the resignation or removal of the Trustee. 
 To secure the Company’s payment obligations in this
Section 7.7, the Trustee shall 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 or interest, if any, on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 
 When the Trustee incurs expenses
or renders services after an Event of Default specified in Section 6.1(7) 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. 
 SECTION 7.8 Replacement of Trustee. 

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor
Trustee’s acceptance of appointment as provided in this Section 7.8. 
 The Trustee may resign in writing at
any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The
Company may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10 hereof;

 (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the
Trustee under any Bankruptcy Law; 
 (c) a Custodian or public officer takes charge of the Trustee or its
property; or 

  
 -70-

 (d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee, after written request by any Holder who has been a Holder for at least six 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. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective,
and the successor Trustee shall have all the rights, powers and the duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, provided that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.7 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.8, the Company’s and the Guarantors’ obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee. 

SECTION 7.9 Successor Trustee by Merger, Etc. 
 If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any
further act shall be the successor Trustee or any Agent, as applicable. 
 SECTION 7.10 Eligibility; Disqualification.

 There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the
United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. The Trustee together with its affiliates shall
at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition. 
 This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(l), (2) and (5). The Trustee is subject to TIA § 310(b) including the provision in
§ 310(b)(1); provided that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or conflicts of interest or participation in other securities, of the
Company or the Guarantors are outstanding if the requirements for exclusion set forth in TIA § 310(b)(1) are met. 

  
 -71-

 SECTION 7.11 Preferential Collection of Claims Against the Company. 

The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has
resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 ARTICLE VIII 

DEFEASANCE; DISCHARGE OF THE INDENTURE 
 SECTION 8.1 Option to Effect Legal Defeasance or Covenant Defeasance. 
 The
Company may, at the option of its Board of Directors and evidenced by a board resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.2 or 8.3 hereof applied to all outstanding Notes and
Note Guarantees upon compliance with the conditions set forth below in this Article VIII. 
 SECTION 8.2 Legal
Defeasance. 
 Upon the Company’s exercise under Section 8.1 hereof of the option applicable to this
Section 8.2, the Company and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes or
Note Guarantees, as applicable, on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the
entire Debt represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in (a) and
(b) below, and to have satisfied all of its other obligations under such Notes 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 shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of and any premium and interest on such Notes when such
payments are due from the trust referred to in Section 8.4(1); (b) the Company’s obligations with respect to such Notes under Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.10 and 4.2
hereof; (c) the rights, powers, trusts, benefits and immunities of the Trustee, including without limitation thereunder, under Section 7.7, 8.5 and 8.7 hereof and the Company’s obligations in connection therewith;
(d) the Company’s rights pursuant to Section 3.7; and (e) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Company may exercise its option under this Section 8.2
notwithstanding the prior exercise of its option under Section 8.3 hereof. 

  
 -72-

 SECTION 8.3 Covenant Defeasance. 

Upon the Company’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the
Company and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from its obligations under the covenants contained in Sections 4.3, 4.5, 4.7, 4.8,
4.9, 4.10, 4.11, 4.12, 4.14, 4.17, 4.18 and 5.1 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes shall 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 shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to
the outstanding Notes, the Company or any of its Subsidiaries may omit to comply with and shall 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 shall not constitute a Default or an Event of Default under
Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.1 hereof of the option applicable
to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(3), (4), (5) and (6) hereof shall not constitute Events of Default.

 Notwithstanding any discharge or release of any obligations pursuant to Section 8.2 or 8.3, the
Company’s obligations in Sections 2.5, 2.6, 2.7, 2.8, 7.7, 8.6 and 8.7 shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.8. After the
Notes are no longer outstanding, the Company’s obligations in Sections 7.7, 8.6 and 8.7 shall survive. 
 SECTION 8.4 Conditions to Legal or Covenant Defeasance. 
 The following
shall be the conditions to the application of either Section 8.2 or 8.3 hereof to the outstanding Notes: 
 (1) the Company must irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for,
and dedicated solely to the benefits of the Holders of such Notes: (A) money in an amount, or (B) Government Securities, which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will
provide, not later than the due date of any payment, money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such Notes on
the Stated Maturity thereof or (if the Company has made irrevocable arrangements satisfactory to the Trustee 

  
 -73-

 
for the giving of notice of redemption by the Trustee in the name and at the expense of the Company) the redemption date thereof, as the case may be, in accordance with the terms of this
Indenture and such Notes; 
 (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee
an Opinion of Counsel stating 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
United States federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Notes will not recognize gain or loss for United States federal income tax
purposes as a result of the deposit, defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such
deposit, defeasance and discharge were not to occur; 
 (3) in the case of Covenant Defeasance, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit and defeasance to be effected
with respect to such Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and defeasance were not to occur; 

(4) no Default or Event of Default with respect to the outstanding Notes shall have occurred and be continuing at the time
of such deposit after giving effect thereto (except for a Default occurring by reason of the Incurrence of Debt the proceeds of which are used for the deposit) or, in the case of Legal Defeasance, either: (A) the Company shall have delivered to
the Trustee an Opinion of Counsel to the effect that, based upon existing precedents, if the matter were properly briefed, assuming no intervening bankruptcy of the Company or any Guarantor between the date of deposit and the 123rd day following the
deposit and assuming that no Holder is an “insider” of the Company under applicable bankruptcy law, after the 123rd day following the deposit, a court should hold that the deposit of monies and/or U.S. government obligations as provided in
clause (1) would not constitute a preference voidable under Section 547 or 548 of the federal bankruptcy laws; or (B) no Default or Event of Default relating to bankruptcy or insolvency shall have occurred and be continuing at any
time on or prior to the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 91st day); 

(5) such Legal Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the
meaning of the TIA (assuming all Notes are in default within the meaning of the TIA); 
 (6) such Legal
Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which the Company is bound; and 

  
 -74-

 (7) the Company shall have delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Legal Defeasance or Covenant Defeasance have been complied with. 
 In the event of a Legal Defeasance or a Discharge, a Holder whose taxable year straddles the deposit of funds and the distribution in redemption to such Holder would be subject to tax on any gain (whether
characterized as capital gain or market discount) in the year of deposit rather than in the year of receipt. In connection with a Discharge, in the event the Company becomes insolvent within the applicable preference period after the date of
deposit, monies held for the payment of the Notes may be part of the bankruptcy estate of the Company, disbursement of such monies may be subject to the automatic stay of the Bankruptcy Code and monies disbursed to Holders may be subject to
disgorgement in favor of the Company’s estate. Similar results may apply upon the insolvency of the Company during the applicable preference period following the deposit of monies in connection with defeasance. 

SECTION 8.5 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. 

Subject to Section 8.6 hereof, all money and Government Securities (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Trustee”) pursuant to Section 8.4 hereof in respect of the outstanding Notes shall be held in trust, shall not be
invested, and shall be 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 or any Subsidiary 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 interest, but such money need not be segregated from other funds except to the extent required by law.

 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash
or Government Securities deposited pursuant to Section 8.4 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. 
 Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from
time to time upon the written request of the Company and be relieved of all liability with respect to any money or Government Securities held by it as provided in Section 8.4 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 8.4(a) 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 8.6 Repayment to Company.

 Subject to any applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or interest, if any, on any Note and remaining unclaimed for one 

  
 -75-

 
year after such principal and premium, if any, or interest has become due and payable shall be paid to the Company or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Note shall thereafter, as an unsecured general creditor, 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, shall 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 shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of
such money then remaining shall be repaid to the Company. 
 SECTION 8.7 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any United States dollars or Government Securities in accordance with
Section 8.2, 8.3 or 8.8 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 obligations of the
Company under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, 8.3 or 8.8 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 8.2, 8.3 or 8.8 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note
following 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 held by the Trustee or Paying Agent. 

SECTION 8.8 Discharge. 
 The Company and the Guarantors may terminate the obligations under this Indenture when: 
 (1) either: (A) all Notes theretofore authenticated and delivered have been delivered to the Trustee for cancellation, or (B) all such Notes not theretofore delivered to the Trustee for
cancellation (i) have become due and payable or (ii) will become due and payable within one year or are to be called for redemption within one year (a “Discharge”) under irrevocable arrangements satisfactory to the Trustee
for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire
indebtedness on the Notes, not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest to the Stated Maturity or date of redemption; 

(2) the Company has paid or caused to be paid all other sums then due and payable under this Indenture by the Company;

 (3) the deposit will not result in a breach or violation of, or constitute a default under, any other
instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (except for a Default occurring by reason of the Incurrence of Debt the proceeds of which are used for the deposit); 

  
 -76-

 (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; and 
 (5) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel reasonably acceptable to the Trustee, each stating that all conditions precedent under this Indenture
relating to the Discharge have been complied with. 
 In the case of clause (1)(B) of this Section 8.8, and
subject to the next sentence and notwithstanding the foregoing paragraph, the Company’s obligations in Sections 2.5, 2.6, 2.7, 2.8, 4.1, 4.2, 4.15 (as to legal existence of the Company only),
7.7, 8.6 and 8.7 shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.8. After the Notes are no longer outstanding, the Company’s obligations in Sections
7.7, 8.6 and 8.7 shall survive any discharge pursuant to Section 8.8. 
 After such delivery or
irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Company’s and the Guarantors’ obligations under the Notes, the Note Guarantees and this Indenture except for those surviving obligations
specified above. 
 In connection with a Discharge, in the event the Company becomes insolvent within the applicable preference
period after the date of deposit, monies held for the payment of the Notes may be part of the bankruptcy estate of the Company, disbursement of such monies may be subject to the automatic stay of the Bankruptcy Code and monies disbursed to Holders
may be subject to disgorgement in favor of the Company’s estate. 
 ARTICLE IX

indentures supplemental to this Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders under this Indenture,
including the definitions herein; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby: 

(1) change the Stated Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in
respect of the principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable on acceleration of the maturity thereof, or change the place of payment where, or the coin or
currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to
redemption or reduce the Redemption Price therefor, 

  
 -78-

 (2) reduce the percentage in aggregate principal amount of the outstanding
Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their
consequences) provided for in this Indenture, 
 (3) modify the obligations of the Company to make Offers to
Purchase upon a Change of Control or from the Excess Proceeds of Asset Sales if such modification was done after the occurrence of such Change of Control or such Asset Sale, 

(4) subordinate, in right of payment, the Notes to any other Debt of the Company, or 

(5) modify any of the provisions of this paragraph or provisions relating to waiver of defaults or those covenants that
cannot be amended or waived without the consent of each holder affected thereby, except to increase any such percentage required for such actions or to provide that certain other provisions of this Indenture cannot be modified or waived without the
consent of the Holder of each outstanding Note affected thereby. 
 The Holders of not less than a majority in aggregate
principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past default under this Indenture and its consequences, except a default: 

(1) in any payment in respect of the principal of (or premium, if any) or interest on any Notes (including any Note which
is required to have been purchased pursuant to an Offer to Purchase which has been made by the Company), or 

(2) in respect of a covenant or provision hereof which under this Indenture cannot be modified or amended without the
consent of the Holder of each outstanding Note affected. 
 The consent of the Holders is not necessary under this Indenture to
approve the particular form of any proposed amendment, modification, waiver, consent or supplemental indenture. It is sufficient if such consent approves the substance of the proposed amendment, modification, waiver, consent or supplemental
indenture. 
 SECTION 9.3 Compliance with Trust Indenture Act. 

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies
with the TIA as then in effect. 
 SECTION 9.4 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
and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if 

  
 -79-

 
notation of the consent is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before
the date the waiver, supplement or amendment becomes effective. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder. 

SECTION 9.5 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall
authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a
new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
 SECTION 9.6 Trustee to Sign
Amendments, Etc. 
 The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if
the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company and the Guarantors may not sign an amendment or supplemental indenture until their respective Boards of Directors approve
it. In signing or refusing to sign any amendment or supplemental indenture the Trustee shall be entitled to receive and (subject to Section 7.1 hereof) shall be fully protected in relying upon an Officers’ Certificate and an Opinion
of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture, that all conditions precedent thereto have been met or waived, that such amendment or supplemental indenture is not
inconsistent herewith, and that it will be valid and binding upon the Company in accordance with its terms.

 NOTE GUARANTEES 

SECTION 11.1 Note Guarantees. 
 (a) Each Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and payment obligations of the Company hereunder and thereunder, and guarantees to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee on behalf of such Holder, that: (i) the principal of and premium, if any and interest on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call
for redemption or otherwise (including, without limitation, the amount that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), together with interest on the overdue principal, if any, and
interest on any overdue interest, to the extent lawful, and all other 

  
 -80-

 
obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of
any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be 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. Each of the Note Guarantees shall be a guarantee of payment and not of collection. 
 (b) Each Guarantor hereby
agrees that its obligations hereunder shall be 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. 

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for 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 or any other Person, protest, notice and all demands whatsoever and covenants that the Note Guarantee of such Guarantor shall not be discharged
as to any Note except by complete performance of the payment obligations contained in such Note and such Note Guarantee or as provided for in this Indenture. Each of the Guarantors hereby agrees that, in the event of a default in payment of
principal or premium, if any, or interest on such Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note,
subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor’s Note Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor agrees that
if, after the occurrence and during the continuance of an Event of Default, the Trustee or the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes,
or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights
and remedies been permitted to be exercised by the Trustee or any of the Holders. 
 (d) If any Holder or the Trustee is
required by any court or otherwise to return to the Company or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by any of them to the Trustee or such
Holder, the Note Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the
Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive the termination of this Indenture. 
 (e) Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article VI hereof for the purposes of the Note Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition 

  
 -81-

 
preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI hereof, such obligations
(whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Note Guarantee of such Guarantor. 
 SECTION 11.2 Execution and Delivery of Note Guarantee. 
 To evidence its
Note Guarantee set forth in Section 11.1, each Guarantor agrees that a notation of such Note Guarantee substantially in the form attached hereto as Exhibit A-1 shall be endorsed on each Note authenticated and delivered by the
Trustee. Such notation of Note Guarantee shall be signed on behalf of such Guarantor by an officer of such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. In
case the officer, board member or director of such Guarantor who shall have signed such notation of Note Guarantee shall cease to be such officer, board member or director before the Note on which such Note Guarantee is endorsed shall have been
authenticated and delivered by the Trustee, such Note nevertheless may be authenticated and delivered as though the Person who signed such notation of Note Guarantee had not ceased to be such officer, board member or director. 

Each Guarantor agrees that its Note Guarantee set forth in Section 11.1 shall remain in full force and effect and apply to
all the Notes notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note Guarantee set forth
in this Indenture on behalf of the Guarantors. 
 SECTION 11.3 Severability. 

In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 11.4 Limitation of Guarantors’
Liability. 
 Each Guarantor and by its acceptance hereof each Holder 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 the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law
or the provisions of any local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Note Guarantee
shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor 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 its Note Guarantee, result in the obligations of such Guarantor under its Note Guarantee constituting a fraudulent transfer or conveyance.

 SECTION 11.5 [Reserved]. 

SECTION 11.6 Releases Following Sales and Other Dispositions. 

In the event of (1) a sale or other transfer or disposition of all of the Capital Stock of any Guarantor to any Person (other than

merger, consolidation or otherwise, to a Person in compliance with the terms of this Indenture, (3) the release or discharge of such Guarantor from its guarantee of Debt under the Credit Agreement (including by reason of the termination of the
Credit Agreement) or the guarantee that resulted in the obligation of such Guarantor to guarantee the Notes, except a discharge or release by or as a result of payment under such guarantee, or (4) if the Notes are Discharged in accordance with
the provisions of Section 8.8 then such Guarantor (or the Person concurrently acquiring such assets of such Guarantor) shall be deemed automatically and unconditionally released and discharged of any obligations under its Note Guarantee,
as may be (but shall not be required to be) evidenced by a supplemental indenture executed by the Company, the Guarantors and the Trustee, without any further action on the part of the Trustee or any Holder; provided that, in the case of an
event described in clauses (1) or (2) above, the Net Cash Proceeds of such sale or other disposition are applied in accordance with Section 4.10. 
 Any Guarantor not released from its obligations under this Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor
under this Indenture as provided in this Article XI. 
 SECTION 11.7 Release of a Guarantor. 

Any Guarantor shall be released and relieved of any obligations under this Note Guarantee, upon Legal Defeasance or satisfaction and
Discharge of the Notes as provided under Sections 8.1 and 8.2. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of the Company’s request for such release accompanied by an Officers’
Certificate certifying as to the compliance with this Section 11.7. Any Guarantor not so released shall remain liable for the full amount of principal of and interest on the Notes as provided in its Note Guarantee. 

SECTION 11.8 Benefits Acknowledged. 
 Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Note
Guarantee are knowingly made in contemplation of such benefits. 
 SECTION 11.9 Future Guarantors. 

Each Person that is required to become a Guarantor after the Issue Date pursuant to Section 4.17 shall promptly execute and
deliver to the Trustee a supplemental indenture pursuant to which such Person shall become a Guarantor. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel

  
 -83-

 
and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Person and that, subject to the application of
bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such
Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms.

 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered to the 

  
 -87-

 
Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the
“Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Section 12.14.

execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the
individual signing such instrument or writing acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also

in reliance thereon, whether or not notation of such action is made upon such Note. 
 (e) If the Company shall solicit from the
Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a board resolution of the Board of Directors of the Company, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders
of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such
record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after
the record date. 
 SECTION 12.15 Security Advice Waiver. 

The Company acknowledges that regulations of the Comptroller of the Currency grant the Company the right to receive brokerage
confirmations of security transactions as they occur. The Company specifically waives such notification to the extent permitted by law and acknowledges that the Company will receive periodic cash transaction statements, which will detail all
investment transactions.

 (Back of 5.625% Senior Note) 

5.625% Senior Notes due 2022 
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

(1) Interest. Actuant Corporation, a Wisconsin corporation, or its successor (together, “Actuant” or the
“Company”) promises to pay interest on the principal amount of this 5.625% Senior Note due 2022 (a “5.625% Senior Note”) at a fixed rate. Actuant will pay interest in United States dollars (except as otherwise provided herein)
semiannually in arrears on June 15 and December 15, commencing on June 15, 2012 or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the 5.625% Senior
Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from April 16, 2012. Actuant shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the 5.625% Senior Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest rate
on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. 
 (2) Method of Payment. Actuant will pay interest on the 5.625% Senior Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders of 5.625%
Senior Notes at the close of business on the June 1 or December 1 preceding the Interest Payment Date, even if such 5.625% Senior Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The 5.625% Senior Notes shall be payable as to principal, premium, if any, and interest at the office or agency of Actuant maintained for such purpose or, at the option of
Actuant, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal
of, premium, if any, and interest on, all Global Notes and all other 5.625% Senior Notes the Holders of which shall have provided written wire transfer instructions to Actuant and the Paying Agent. Such payment shall be in such coin or currency of
the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 Any payments
of principal of this 5.625% Senior Note prior to Stated Maturity shall be binding upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted
hereon. The amount due and payable at the maturity of this Note shall be payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes. 

  
 A-5

 (3) Paying Agent and Registrar. Initially, U.S. Bank National Association, the
Trustee under the Indenture, shall act as Paying Agent and Registrar. Actuant may change any Paying Agent or Registrar without notice to any Holder. Actuant or any of its Subsidiaries may act in any such capacity. 

(4) Indenture. Actuant issued the 5.625% Senior Notes under an Indenture, dated as of April 16, 2012 (as amended and
supplemented from time to time, the “Indenture”), among Actuant Corporation, the Guarantors and the Trustee. The terms of the 5.625% Senior Notes include those stated in the Indenture and those made a part of the Indenture by reference to
the Trust Indenture Act of 1939, as in effect from time to time (the “TIA”). To the extent the provisions of this 5.625% Senior Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The 5.625% Senior Notes
are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The 5.625% Senior Notes issued on the Issue Date are senior obligations of Actuant limited to $300,000,000 in aggregate principal
amount, plus amounts, if any, sufficient to pay premium, if any, and interest on outstanding 5.625% Senior Notes as set forth in Paragraph 2 hereof. The Indenture permits the issuance of Additional Notes subject to compliance with certain
conditions. 
 The payment of principal and interest on the 5.625% Senior Notes is unconditionally guaranteed on a senior basis
by the Guarantors. 
 (5) Optional Redemption. 
 (a) Except as set forth below, the Notes are subject to redemption, at the option of the Company, in whole or in part, at any time and from time to time on or after June 15, 2017, upon not less than
30 nor more than 60 days’ notice at the following Redemption Prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus accrued and unpaid interest, if any, to, but not including, the redemption date
(subject to the right of Holders of record on the relevant regular record date to receive interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the 12-month period beginning June 15 of the
years indicated:

the preceding paragraphs, prior to June 15, 2015, the Company may, with the net proceeds of one or more Qualified Equity Offerings, redeem up to 35% of the aggregate principal amount of the outstanding Notes at a redemption price equal to
105.625% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of redemption; provided that at least 65% of the principal amount of Notes originally issued on the Issue Date remains outstanding
immediately after the occurrence of any such redemption (excluding Notes held by the Company or its Subsidiaries) and that any such redemption occurs within 90 days following the closing of any such Qualified Equity Offering. 

(6) Mandatory Redemption. Actuant shall not be required to make mandatory redemption or sinking fund payments with respect to the
5.625% Senior Notes except as set forth in Sections 4.10 and 4.14 of the Indenture. 
 (7) Repurchase at Option
of Holder. 
 (a) Upon the occurrence of a Change of Control, Actuant will make an Offer to Purchase (the “Change of
Control Offer”) all of the outstanding Notes at a Purchase Price in cash equal to 101% of the principal amount tendered, together with accrued interest, if any, to but not including the Purchase Date. Within 30 days after any Change of Control,
Actuant will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control setting forth the procedures governing the Change of Control Offer required by the Indenture. 

(b) Upon the occurrence of certain Asset Sales, the Company may be required to make an Offer to Purchase. 

(c) Holders of the 5.625% Senior Notes that are the subject of an Offer to Purchase will receive notice of an Offer to Purchase pursuant
to an Asset Sale or a Change of Control from Actuant prior to any related purchase date and may elect to have such 5.625% Senior Notes purchased by completing the form titled “Option of Holder to Elect Purchase” appearing below.

 (8) Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the
redemption date to each Holder whose 5.625% Senior Notes are to be redeemed at its registered address. 5.625% Senior Notes in denominations larger than $2,000 may be redeemed in part but only in minimum denominations of $2,000 and integral multiples
of $1,000 in excess thereof, unless all of the 5.625% Senior Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on the 5.625% Senior Notes or portions hereof called for redemption. 

(9) [Reserved]. 
 (10) Denominations, Transfer, Exchange. The 5.625% Senior Notes are in registered form without coupons in initial denominations of $2,000 and integral multiples of $1,000 in excess thereof. The
transfer of the 5.625% Senior Notes may be registered and the 5.625% Senior Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer

  
 A-7

 
documents and Actuant may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. Actuant need not exchange or register the transfer of any 5.625% Senior Note or
portion of a 5.625% Senior Note selected for redemption, except for the unredeemed portion of any 5.625% Senior Note being redeemed in part. Also, it need not exchange or register the transfer of any 5.625% Senior Notes for a period of 15 days
before a selection of 5.625% Senior Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 (11) Persons Deemed Owners. The registered holder of a 5.625% Senior Note may be treated as its owner for all purposes. 
 (12) Amendment, Supplement and Waiver. Subject to the following paragraphs, the Indenture and the 5.625% Senior Notes may be amended or supplemented with the consent of the Holders of at least a

 A-8

resulted in the acceleration of the maturity of such Debt prior to its express maturity or shall constitute a failure to pay at least $30.0 million of such Debt when due and payable after the expiration of any applicable grace period with respect
thereto, and such Debt, in either case, is not discharged or such acceleration shall not 

  
 A-10

 
have been rescinded or annulled, within 30 days after notice thereof shall have been given, by registered mail, to the Company by either the Trustee, or to the Company and the Trustee by the
Holders of at least 25% of the outstanding principal amount of the Notes; 
 (6) the entry against the Company or

million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or 

(7) (i) the Company, any Significant Subsidiary or each member of any group of Restricted Subsidiaries that, taken as a
whole (and considered as a single entity), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 
 (a) commences a voluntary case, 
 (b) consents to the entry of an
order for relief against it in an involuntary case, 
 (c) consents to the appointment of a Custodian of it or
for all or substantially all of its property, 
 (d) makes a general assignment for the benefit of its creditors,
or 
 (e) admits in writing its inability generally to pay its debts as the same become due; 

(ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(a) is for relief against the Company, any Significant Subsidiary or each member of any group of Restricted Subsidiaries
that, taken together (and considered as a single entity), would constitute a Significant Subsidiary, in an involuntary case; 
 (b) appoints a Custodian of the Company, any Significant Subsidiary or each member of any group of Restricted Subsidiaries that, taken together (and considered as a single entity), would constitute a
Significant Subsidiary or for all or substantially all of the property of the Company, any Significant Subsidiary or each member of any group of Restricted Subsidiaries that, taken together (and considered as a single entity), would constitute a
Significant Subsidiary; or 

  
 A-11

 (c) orders the liquidation of the Company, any Significant Subsidiary or
each member of any group of Restricted Subsidiaries that, taken together (and considered as a single entity), would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 

If an Event of Default (other than an Event of Default specified in clause (7) above with respect to the Company) occurs and is
continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable
immediately by a notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate
principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on the Notes, have been cured or waived as
provided in the Indenture. 
 In the event of a declaration of acceleration of the Notes solely because an Event of Default
described in clause (5) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to
clause (5) shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the
rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes. 

If an Event of Default specified in clause (7) above occurs with respect to the Company, the principal of and any accrued interest
on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
 (14) Trustee Dealings with Actuant. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for Actuant, the Guarantors or their
respective Affiliates, and may otherwise deal with Actuant, the Guarantors or their respective Affiliates, as if it were not the Trustee. 
 (15) No Recourse Against Others. No director, officer, employee, agent, stockholder, general or limited partner or incorporator, past, present or future, of the Company, or any of its Subsidiaries,
as such or in such capacity, shall have any personal liability for any obligations of the Company or any Guarantor under the Notes, any Note Guarantee or the Indenture by reason of his, her or its status as such director, officer, employee, agent,
stockholder, general or limited partner or incorporator. The Holder of this 5.625% Senior Note by accepting this 5.625% Senior Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the
Notes and the Note Guarantees.

 Exhibit 4.2 
 SUPPLEMENTAL INDENTURE 
 This Supplemental Indenture, dated as of
April 16, 2012 (this “Supplemental Indenture”), among Actuant Corporation, a Wisconsin corporation (the “Company”), the Subsidiary Guarantors under the Indenture referred to below (the
“Guarantors”) and U.S. Bank National Association, as trustee (the “Trustee”). 
 WITNESSETH

 WHEREAS, the Company, the Guarantors and the Trustee are parties to an Indenture dated as of June 12, 2007 (as may be
supplemented from time to time, the “Indenture”), providing for the issuance of the Company’s 6 7/8% Senior Notes due 2017 (the “Notes”); 

WHEREAS, Section 9.2 of the Indenture permits the execution of supplemental indentures for the purpose of eliminating provisions of
the Indenture with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes issued under the Indenture; 
 WHEREAS, the Company desires and has requested the Trustee to join with it and the Guarantors in entering into this Supplemental Indenture for the purpose of amending the Indenture and the Notes in
certain respects as permitted by Section 9.2 of the Indenture; 
 WHEREAS, the Company has been soliciting consents to this
Supplemental Indenture upon the terms and subject to the conditions set forth in its Offer to Purchase and Consent Solicitation Statement dated April 2, 2012 and the Consent and Letter of Transmittal (which together, including any amendments,
modifications or supplements thereto, constitute the “Tender Offer”); and 
 NOW, THEREFORE, for and in
consideration of the foregoing premises, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of the Notes, as follows: 
 ARTICLE I 
 AMENDMENT OF THE INDENTURE 

Section 1.1 Deletion of Certain Provisions. 
 (a) Indenture. The following provisions of the Indenture are hereby deleted and eliminated in their entirety, without redesignation of any other provision of the Indenture: 

 

			
	 Section 4.3
	  	Section 4.12
	 Section 4.4
	  	Section 4.13
	 Section 4.7
	  	Section 4.17
	 Section 4.8
	  	Section 4.18
	 Section 4.9
	  	Section 4.19
	 Section 4.11
	  	Section 11.9

 In addition, all references in the Indenture to any of the foregoing provisions shall also be deemed
deleted and eliminated in their entirety. 

  
 1 

 (b) Definitions. All definitions in the Indenture that, as a result of the deletions
set forth in Section 1.1, define terms that no longer appear in Indenture, are hereby deleted and eliminated in their entirety. 
 Section 1.2 Amendment and Restatement of Certain Provisions. 

(a) Execution and Authentication. Section 2.2 of the Indenture is hereby deleted in its entirety and replaced with the
following Section 1.2(a)(i) of this Supplement: 
 (i) SECTION 2.2. Execution and Authentication.

 An Officer shall 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 shall
nevertheless be valid. 
 A Note shall not be valid until authenticated by the manual signature of a Responsible
Officer of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee shall, upon a written order of the Company signed by one Officer directing the Trustee to authenticate the Notes and certifying that all conditions precedent to the issuance of the Notes
contained herein have been complied with, authenticate Notes for original issue (i) in an aggregate principal amount up to $250,000,000 on the date of this Indenture and (ii) Additional Notes from time to time. 

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Notes. Any such
appointment shall be evidenced by an instrument signed by a Responsible Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, 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 the Company or an Affiliate of the Company.

 (b) Limitation on Asset Sales. Section 4.10 of the Indenture is hereby deleted in its entirety and replaced with
the following Section 1.2(b)(i) of this Supplement: 
 (i) SECTION 4.10. Limitation on Asset Sales.

 Within 540 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Company (or the applicable
Restricted Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option: 
 (1) to permanently
repay or prepay Debt outstanding under the Credit Agreement and, if the Debt repaid is revolving credit Debt, to correspondingly reduce commitments with respect thereto; 

  
 2 

 (2) to acquire all or substantially all of the assets of, or any Capital
Stock of, another Permitted Business; 
 (3) to make capital expenditures or to acquire other assets that are
not classified as current assets under GAAP and that are used or useful in a Permitted Business; or 
 (4) any
combination of the foregoing. 
 Any Net Cash Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, within thirty days thereof, the Company will make an Offer to
Purchase to all Holders of Notes and Additional Notes equal to the Excess Proceeds. The offer price in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable
in cash. If any Excess Proceeds remain after consummation of an Offer to Purchase, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and Additional Notes
tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such Additional Notes to be purchased on a pro rata basis. Upon completion of each Offer to Purchase, the amount of Excess Proceeds
will be reset at zero. 
 The Company will comply with the requirements of any applicable securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Offer to Purchase. To the extent that the provisions of any securities laws or regulations conflict with the
Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such
compliance. 
 (c) Consolidation, Merger, Conveyance, Transfer or Lease. Section 5.1 of the Indenture is hereby
deleted in its entirety and replaced with the following Section 1.2(c)(i) of this Supplement: 
 (i) SECTION
5.1. Consolidation, Merger, Conveyance, Transfer or Lease. 
 The Company will not in any transaction or
series of transactions, consolidate with or merge into any other Person (other than a merger of a Restricted Subsidiary into the Company in which the Company is the continuing Person or the merger of a Restricted Subsidiary into or with another
Restricted Subsidiary or another Person that as a result of such transaction becomes or merges into a Restricted Subsidiary), or transfer all or substantially all of the assets of the Company and its Restricted Subsidiaries (determined on a
consolidated basis), taken as a whole, to any other Person, unless: 
 (i) either: (a) the Company shall be
the continuing Person or (b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged, or the Person that acquires, by sale, assignment, conveyance, transfer, lease or disposition, all or
substantially all of the property and assets of the Company (such Person, the “Surviving Entity”), (1) shall be a corporation, organized and validly existing under the laws of the United States, any political subdivision
thereof or any state thereof or the District of Columbia and (2) shall expressly assume, by a supplemental indenture, the due and punctual payment of all amounts due in respect of the principal of (and premium, if any) and interest on all the
Notes and the performance of the covenants and obligations of the Company under this Indenture; and 

  
 3 

 (ii) the Company delivers, or causes to be delivered, to the Trustee, in
form and substance reasonably satisfactory to the Trustee, an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition complies with the
requirements of this Indenture. ; 
 For all purposes of this Indenture and the Notes, Subsidiaries of any
Surviving Entity will, upon such transaction or series of related transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture and all Debt, and all Liens on property or assets, of the Surviving
Entity and its Subsidiaries that was not Debt, or were not Liens on property or assets, of the Company and its Subsidiaries immediately prior to such transaction or series of related transactions shall be deemed to have been Incurred upon such
transaction or series of related transactions. 
 (d) Events of Default. Section 6.1 of the Indenture is hereby
deleted in its entirety and replaced with the following Section 1.2(d)(i) of this Supplement: 
 (i) SECTION
6.1 Events of Default. 
 Each of the following constitutes an “Event of Default”:

 (1) default in the payment in respect of the principal of (or premium, if any, on) any Note at its maturity (whether at
Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise); 
 (2) default in the payment of any
interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days; 
 (3)
except as permitted herein, any Note Guarantee of any Significant Subsidiary shall for any reason cease to be, or it shall be asserted by such Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms;

  
 4 

 (4) default in the performance, or breach, of any covenant or agreement of the Company or
any Guarantor in this Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in clauses (1), (2) or (3) above), and continuance of such default or breach for a period of
60 days, in each case, after written notice thereof has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes; 

(e) Acceleration. Section 6.2 of the Indenture is hereby deleted in its entirety and replaced with the following
Section 1.2(e)(i) of this Supplement: 
 (i) SECTION 6.2 Acceleration. 

If an Event of Default occurs and is continuing, then and in every such case the Trustee or the Holders of not less than
25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders);
provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may rescind and annul such acceleration: 

(1) if the rescission would not conflict with any judgment or decree; 

(2) if all existing Events of Default have been cured or waived except nonpayment of principal and interest that has
become due solely because of this acceleration; 
 (3) if the Company has paid to the Trustee its reasonable
compensation and reimbursed the Trustee of its expenses, disbursements and advances; and 
 (4) in the event of
a cure or waiver of an Event of Default of the type set forth in Section 6.1(7), the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. 

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto. 

  
 5 

 (f) Covenant Defeasance. Section 8.3 of the Indenture is hereby deleted in its
entirety and replaced with the following Section 1.2(f)(i) of this Supplement: 
 (i) SECTION 8.3.
Covenant Defeasance. 
 Upon the Company’s exercise under Section 8.1 hereof of the
option applicable to this Section 8.3, the Company and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from its obligations under the covenants contained in
Sections 4.5, 4.10, and 4.14 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall
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 shall continue to be deemed
“outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the
Company or any of its Subsidiaries may omit to comply with and shall 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 shall not constitute a Default or an Event of Default under Section 6.1 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3,
subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(3), (4), (5) and (6) hereof shall not constitute Events of Default. 

(g) Definitions. All definitions in the Indenture that, as a result of the deletions set forth in Section 1.2(a), define
terms that no longer appear in Indenture, are hereby deleted and eliminated in their entirety. 
 ARTICLE II

 6

provisions in this Supplemental Indenture or in the Notes shall be held invalid, illegal or unenforceable, in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining
provisions shall not in any way be affected or impaired thereby, it being intended that all of the provisions hereof shall be enforceable to the full extent permitted by law. 
 Section 2.7 Counterparts. 
 This Supplement may be executed in
any number of counterparts, each of which when so executed shall be deemed to be an original, but all of which shall together constitute one and the same instrument.
