acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness incurred in connection therewith, the pro forma calculations shall be determined in good faith

officer of the Company, which estimate shall be conclusive); plus (iii) the product of (x) the amount of all dividend payments on any series of Permitted Subsidiary Preferred Stock times (y) a fraction, the numerator of which

estimate shall be conclusive); provided that, with respect to any series of Preferred Stock that did not pay cash dividends during such period but that is eligible to pay dividends during any period prior to the maturity date of the Notes,

Trustee that such designation complies with Section 4.07 hereof, and (ii) each Subsidiary to be so designated and each of its Subsidiaries has not at the time of designation, and does
not thereafter, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable with respect to any Indebtedness pursuant to which the lender has recourse to any of the assets of the Company or any of its Restricted
Subsidiaries. The Board of Directors of the Company may designate any Unrestricted Subsidiary to be a Restricted Subsidiary only if (x) immediately after giving effect to such designation, the Company is able to incur at least $1.00 of
additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 4.09 hereof and (y) immediately before and immediately after giving effect to such designation, no Default or Event of Default shall have occurred and
be continuing. Any such designation by the Board of Directors of the Company shall be evidenced by a Board Resolution giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the foregoing
provisions. 
 Actions taken by an Unrestricted Subsidiary will not be deemed to have been taken, directly or indirectly, by the Company or
any Restricted Subsidiary. 
 “Weighted Average Life to Maturity” means, when applied to any Indebtedness at any date, the
number of years obtained by dividing (i) the then-outstanding aggregate principal amount of such Indebtedness into (ii) the sum of the total of the products obtained by multiplying: (A) the amount of each then-remaining installment,
sinking fund, serial maturity or other required payment of principal, including payment at final maturity, in respect thereof by (B) the number of years (calculated to the nearest one-twelfth) which will elapse between such date and the making
of such payment. 
 “Wholly Owned Subsidiary” of any Person means any Subsidiary of such Person of which all the
outstanding voting securities (other than in the case of a Restricted Subsidiary that is incorporated in a jurisdiction other than a State in the United States of America or the District of Columbia, directors’ qualifying shares or an
immaterial amount of shares required to be owned by other Persons pursuant to applicable law) are owned by such Person or any Wholly Owned Subsidiary of such Person.

ARTICLE II 
 THE NOTES 

SECTION 2.01. Form and Dating. 

Provisions relating to the Initial Notes, the Private Exchange Notes and the Exchange Notes are set forth in the Rule 144A/Regulation S
Appendix attached hereto (the “Appendix”) which is hereby incorporated in and expressly made part of this Indenture. The Initial Notes and the Trustee’s certificate of authentication with respect thereto shall be substantially
in the form of Exhibit A to the Appendix, which is hereby incorporated in and expressly made a part of this Indenture. The Exchange Notes, the Private Exchange Notes and the Trustee’s certificate of authentication with respect thereto
shall be substantially in the form of Exhibit B to the Appendix, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements
to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Note shall be dated the date of its authentication. The terms of the Notes set forth in
the Appendix and Exhibits A and B to the Appendix are part of the terms of this Indenture. 
 SECTION 2.02. Execution and
Authentication. 
 Two Officers 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 the Trustee authenticates the Note, the Note shall be valid
nevertheless. 
 A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on
the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

  
 27 








 On the Issue Date, the Trustee shall authenticate and deliver $1,200,000,000 of 6.500% Senior
Subordinated Notes due 2024 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the
Company signed by two Officers or by an Officer and an Assistant Secretary of the Company (each an “Authentication Order”). Such Authentication Order shall specify the amount of the Notes to be authenticated and the date on which
the original issue of Notes is to be authenticated, whether the Notes are to be Initial Notes, Additional Notes, Exchange Notes or Private Exchange Notes or such other information as the Trustee shall reasonably request and, in the case of an
issuance of Additional Notes pursuant to Section 2.14 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09. 

The Notes shall be issued only in registered form, without coupons and only in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. 
 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate the Notes. 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 the Registrar or any Paying Agent or agent for service of notices and demands. 
 In authenticating such Notes, and accepting
the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall receive, and shall be fully protected in relying upon: 

(a) A copy of the resolution or resolutions of the Board of Directors in or pursuant to which the terms and form of the Notes were
established, certified by the Secretary or an Assistant Secretary of the Company, to have been duly adopted by the Board of Directors and to be in full force and effect as of the date of such certificate, and if the terms and form of such Notes are
established by an Officers’ Certificate pursuant to general authorization of the Board of Directors, such Officers’ Certificate; 

(b) an executed supplemental indenture, if any; 

(c) an Officers’ Certificate delivered in accordance with Section 13.05 hereof; and 

(d) an Opinion of Counsel which shall state that the Notes have been duly authorized by all necessary corporate action of the Company and,
when executed, issued and authenticated in accordance with the terms of the Indenture and delivered by the Trustee, will be the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms,
subject to any conditions and qualifications specified in such Opinion of Counsel. 
 SECTION 2.03. Registrar and Paying Agent. 

The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the
“Registrar”) and an office or agency where Notes 

  
 28 








 
may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their registration of transfer and exchange. The Company may have one
or more additional paying agents. The term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or the Registrar without notice to any Holder. 

The Company shall enter into an appropriate agency agreement with the Registrar or any Paying Agent not a party to this Indenture, which shall
incorporate the terms of the TIA. The agency 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 a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly Owned Subsidiary incorporated or organized within the
United States of America may act as Paying Agent, Registrar or transfer agent. 
 The Company initially appoints the Depository (as defined
in the Appendix) to act as depositary with respect to the Global Notes (as defined in the Appendix). 
 The Company initially appoints the
Trustee as Registrar and Paying Agent in connection with the Notes. The Registrar and Paying Agent shall be entitled to the rights and immunities of the Trustee hereunder. 

SECTION 2.04. Paying Agent to Hold Money in Trust. 

Prior to 10:00 a.m., New York time, on or prior to each due date of the principal, premium, if any, and interest on any Note, the Company
shall deposit with the Paying Agent a sum sufficient to pay such principal, premium and interest when so becoming due. 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 Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on the Notes and shall notify the Trustee in writing 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. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent (if other than the
Company or a Subsidiary of the Company) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. 

SECTION 2.05. 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 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 seven Business Days before each interest payment date and at such other times as the Trustee may
request in writing, a list in such form and as of such date as the Trustee may 

  
 29 








 
reasonably require of the names and addresses of Holders, and the Company shall otherwise comply with TIA §312(a). 

SECTION 2.06. Transfer and Exchange. 

(a) The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note being transferred for
registration of transfer. When a Note is presented to the Registrar with a request to register a transfer, such Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform
Commercial Code are met. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. No
service charge shall be made for any registration of transfer or exchange or redemption of the Notes, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith
(other than any such transfer taxes or other similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 or 9.05 hereof). 

(b) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except
the unredeemed portion of any Note being redeemed in part. 
 (c) All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

(d) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the
opening of business 15 days before the day of the mailing of notice of redemption under Section 3.03 hereof and ending at the close of business on such day, (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. 

(e) Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Note may
be effected only through a book-entry system maintained by (a) the Holder of such Global Note (or its agent or the person on whose behalf the Global Note is held) or (b) any Holder of a beneficial interest in such Global Note, and that
ownership of beneficial interest in such Global Note shall be required to be reflected in a book entry. 
 (f) Prior to due presentment for
the registration of a transfer of any Note, the Trustee, any Paying Agent, the Registrar 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, premium, if any, and interest on such Notes and for all other 

  
 30 








 
purposes, and none of the Trustee, any Paying Agent, the Registrar or the Company shall be affected by notice to the contrary. 

(g) None of the Company, the Trustee, any agent of the Company or the Trustee (including any Paying Agent or Registrar) will have any
responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership
interests. 
 (h) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among depositary participants or beneficial owners of interest in any global security) 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 2.07. Replacement Notes. 

If a mutilated Note is surrendered to the Registrar, or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If
required by the Trustee or the Company, such Holder shall furnish an indemnity or a security bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss which
any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder 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
proportionally with all other Notes duly issued hereunder. 
 SECTION 2.08. Outstanding Notes. 

Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those reductions in the interest in
a Global Note effected by the Trustee in accordance with the provisions of this Indenture, those delivered to it for cancellation and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does
not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant to
Section 2.07 hereof, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser. 

  
 31 








 If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases
to be outstanding, and interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any
thereof) segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal, premium, if any, and interest payable on that date with respect to the Notes (or portions
thereof) to be redeemed or maturing, as the case may be, then, on and after that date, such Notes (or portions thereof) shall cease to be outstanding, and interest on them shall cease to accrue. 

SECTION 2.09. Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with 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 that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. 

SECTION 2.10. Temporary Notes. 

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

SECTION 2.11. Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange,
payment, replacement or cancellation in accordance with its customary procedures and, if requested in writing, deliver a certificate of such disposal to the Company unless the Company directs the Trustee in writing to deliver canceled Notes to the
Company. The Company may not issue new Notes to replace Notes that it has redeemed, paid or that have been delivered to the Trustee for cancellation. 

SECTION 2.12. Defaulted Interest. 

If the Company defaults in a payment of interest on the Notes, the Company shall pay defaulted interest (plus interest on such defaulted
interest at the applicable interest rate on the Notes to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Company shall


  
 32 








 
fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee (provided that no such special record date shall be less than 10 days
prior to the related payment date for such defaulted interest) and shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the related payment date and the amount of defaulted interest to be paid. 

SECTION 2.13. CUSIP or ISIN Numbers. 

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

SECTION 2.14. Issuance of Additional Notes. 

The Company shall be entitled, subject to its compliance with Section 4.09, to issue Additional Notes under this Indenture which shall
have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Notes issued on the Issue Date, any Additional Notes and all Exchange Notes or Private Exchange Notes
issued in exchange therefor shall be treated as a single class for all purposes under this Indenture. 
 With respect to any Additional
Notes, the Company shall set forth in a Board Resolution and an Officers’ Certificate of the Company, a copy of each 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 and the “CUSIP”, “ISIN” or other similar identification numbers of such
Additional Notes; 
 (3) whether such Additional Notes shall be Transfer Restricted Notes and issued in the form of Initial Notes as
set forth in the Appendix to this Indenture or shall be issued in the form of Exchange Notes as set forth in Exhibit B to the Appendix; and 

(4) if any Additional Notes are not fungible with any of the Notes then outstanding for U.S. federal income tax purposes, such Additional
Notes will have a separate CUSIP number. 

  
 33 








 ARTICLE III 

Redemption And Prepayment 

SECTION 3.01. Notices to Trustee. 

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the
Trustee, at least 45 days but not more than 60 days (or such shorter period, as agreed to by the Trustee) before a redemption date, an Officers’ Certificate setting forth (i) the redemption date, (ii) the redemption price and
(iii) the “CUSIP”, “ISIN” or other similar identification numbers of the Notes to be redeemed. 
 SECTION 3.02.
Selection of Notes to Be Redeemed. 
 If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any
time, DTC shall select the Notes to be redeemed or purchased among the Holders in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed, provided for the avoidance of doubt; or, if the
Notes are not so listed, by lot or otherwise in accordance with the procedures of the depository. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30
nor more than 60 days prior to the redemption date from the outstanding Notes not previously called for redemption. 
 Notes and portions of
Notes selected shall be in integral multiples of $1,000. The provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

SECTION 3.03. Notice of Redemption. 

Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company shall
send to The Depository Trust Company (“DTC”) in the case of Global Notes, or mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address in the case of
certificated notes. 
 The notice shall identify the Notes to be redeemed, including “CUSIP”, “ISIN” or other similar
identification numbers, if any, and shall state: 
 (a) the redemption date; 

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

(c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the
redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; 

(d) the name and address of the Paying Agent; 

  
 34 








 (e) that Notes called for redemption must be surrendered to the Paying Agent to
collect the redemption price; 
 (f) that, unless the Company defaults in making such redemption payment, interest on Notes
called for redemption ceases to accrue on and after the redemption date; 
 (g) the paragraph of the Notes and/or
Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 
 (h) that no
representation is made as to the correctness or accuracy of the “CUSIP”, “ISIN” or other similar identification number, if any, listed in such notice or printed on the Notes. 

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided,
however, that the Company shall have delivered to the Trustee, at least 5 days prior to the date the Company wishes the notice to be given, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in the preceding paragraph. 
 SECTION 3.04. Effect of Notice of Redemption. 

Once notice of redemption is sent or mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due
and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
 SECTION 3.05. Deposit of
Redemption Price. 
 Prior to 10:00 a.m New York time on the redemption date, the Company shall deposit with the Trustee or with the
Paying Agent money sufficient to pay the redemption price of, and accrued interest on, all Notes to be redeemed 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 of, and accrued interest on, all Notes to be redeemed. 

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date. If any Note called for redemption 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 until such principal is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the applicable interest rate on the Notes. 

  
 35 








 SECTION 3.06. Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company’s written request, the Trustee shall
authenticate for the Holder at the expense of the Company, a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 

SECTION 3.07. Optional Redemption. 

(a) On and after the date hereof, the Company shall be entitled to redeem the Notes (which includes Additional Notes, if any) at its option,
in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as percentages of the principal amount thereof) (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date) if redeemed during the twelve-month period commencing on July 15 of the year set forth below: 
  

					
	 Year
	  	Percentage	 
	 2019
	  	 	103.250	% 
	 2020
	  	 	101.625	% 
	 2021 and thereafter
	  	 	100.000	% 

 (b) The Company shall pay all accrued and unpaid interest on the Notes redeemed (subject to the right of
Holders of record on the relevant record date to receive interest due on the related interest payment date). 
 (c) Any redemption pursuant
to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. 
 (d) In addition, prior to
July 15, 2017, the Company shall be entitled at its option on one or more occasions to redeem Notes (which includes Additional Notes, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Notes
(which includes Additional Notes, if any) originally issued at a redemption price (calculated by the Company and expressed as a percentage of principal amount) of 106.500%, plus accrued and unpaid interest, if any, to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), with an amount not to exceed the net cash proceeds from one or more Equity Offerings (provided that if the Equity
Offering is an offering by Holdings, a portion of the Net Cash Proceeds thereof equal to the amount required to redeem any such Notes is contributed to the equity capital of the Company); provided, however, that: (1) at least 65%
of such aggregate principal amount of Notes (which includes Additional Notes, if any) remains outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly by the Company or its Affiliates); and
(2) each such redemption occurs within 90 days after the date of the related Equity Offering. 
 (e) Notice of any redemption upon any
Equity Offering may be given prior to the completion thereof, and any such redemption or notice may, at the Company’s discretion, be subject to the completion of the related Equity Offering. 

  
 36 








 (f) Prior to the Initial Redemption Date, the Company shall be entitled at its option to redeem
all or a portion of the Notes at a redemption price (calculated by the Company) equal to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date (subject to the
right of Holders on the relevant record date to receive interest due on the relevant interest payment date). Notice of such redemption shall be sent to DTC in the case of Global Notes, or mailed by first-class mail to each Holder’s registered

 The Net Proceeds Offer shall remain open for a
period of 20 Business Days following its commencement or such longer period as may be required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase
Date”), the Company shall purchase the Net Proceeds Offer Amount (as defined in Section 4.10 hereof) or, if less than the Net Proceeds Offer Amount has been tendered, all Notes tendered in response to the Net Proceeds Offer. Payment

payable to Holders who tender Notes pursuant to the Net Proceeds Offer. 
 Upon the commencement of a Net Proceeds Offer, the Company shall
send, by first class mail, a notice to the Trustee and each of the Holders. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Net Proceeds Offer. The Net Proceeds Offer shall be
made to all Holders. The notice, which shall govern the terms of the Net Proceeds Offer, shall state: 
 (a) that the Net
Proceeds Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Net Proceeds Offer shall remain open and, if the Net Proceeds Offer is also made to holders of other Senior Subordinated Debt of
the Company or a Restricted Subsidiary of the Company pursuant to Section 4.10 hereof, the notice shall identify such Senior Subordinated Debt and state that the Net Proceeds Offer is also made to holders of such Senior Subordinated Debt;

 (b) the Net Proceeds Offer Amount, the purchase price and the Purchase Date;

pursuant to a Net Proceeds Offer may only elect to have such Note purchased in denominations of $2,000 and integral multiples of $1,000 in excess thereof; 

(f) that Holders electing to have a Note purchased pursuant to any Net Proceeds Offer shall be required to surrender the Note,
with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in
the notice at least three days before the Purchase Date; 
 (g) that Holders shall be entitled to withdraw their election if
the Company, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the
Note the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Note purchased; 

(h) that, if the aggregate principal amount of Notes surrendered by Holders and other Senior Subordinated Debt surrendered by
the holders thereof exceeds the Offer Amount, the Company shall select the Notes and other Senior Subordinated Debt of the Company or a Restricted Subsidiary of the Company to be purchased in accordance with the depository’s procedures (based
on the amounts of Notes and such other Senior Subordinated Debt tendered and with such adjustments as may be deemed appropriate by the Company so that only Notes or other Senior Subordinated Debt in denominations of $2,000 and integral multiples of
$1,000 in excess thereof, shall be purchased); and 
 (i) that Holders whose Notes were purchased only in part shall be
issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 

On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent
necessary, the Net Proceeds Offer Amount of Notes and other Senior Subordinated Debt of the Company or a Restricted Subsidiary of the Company or portions thereof tendered pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer
Amount has been tendered, all Notes and other Senior Subordinated Debt of the Company or a Restricted Subsidiary of the Company or portions thereof tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes or
such other Senior Subordinated Debt or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depository or the Paying Agent, as the case may be, shall promptly (but in any
case not later than five days after the Purchase Date) 

  
 38 








 
mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue
a new Note, and the Trustee, upon written request from the Company, shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall
be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Net Proceeds Offer on the Purchase Date. 

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the
provisions of Sections 3.01 through 3.06 hereof. 
 To the extent that the provisions of any securities laws or regulations conflict
with this Section 3.09 or Section 4.10 hereof, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 3.09 or Section 4.10 hereof.

any annual reports, information, documents and other reports pursuant to TIA § 314(a), delivery of such information, reports or certificates or any annual reports, information, documents and other reports to the Trustee is for
informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 SECTION 4.04.
Compliance Certificate. 
 (a) The Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall

under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture and further stating, as to each such Officer signing such certificate,
that, to the best of his or her knowledge, the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and
conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect
thereto) and that, to the best of his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a
description of the event and what action the Company is taking or proposes to take with respect thereto. For purposes of this paragraph, such compliance shall be determined without regard to any period of grace or requirement of notice provided
under this Indenture. 
 (b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any

SECTION 4.06. Stay, Extension and Usury Laws. 

The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and
each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it 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.

time of such Restricted Payment or immediately after giving effect thereto: 
 (i) a Default or an Event of Default shall
have occurred and be continuing; or 
 (ii) the aggregate amount of Restricted Payments (including such proposed Restricted

without duplication:

(v) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of
such loss) of the Company earned subsequent to October 1, 2010 and on or prior to the date the

Restricted Payment occurs (the “Reference Date”) (treating such period as a single accounting period); plus 

(w) 100% of the aggregate net cash proceeds (including the fair market value of property (as determined by the Company in
good faith) other than cash that would constitute Marketable Securities or a Permitted Business) received by the Company from any Person (other than a Subsidiary of the Company) from the issuance and sale subsequent to December 14, 2010 and on

exchange subsequent to December 14, 2010 of any Indebtedness of the Company for Qualified Capital Stock of the Company (less the amount of any cash, or the fair value of any other property, distributed by the Company upon such conversion or
exchange); provided, however, that the foregoing amount shall not exceed the net cash proceeds received by the Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding net cash proceeds from sales to a
Subsidiary of the Company or to an employee stock ownership plan or a trust established by the Company or any of its Subsidiaries for the benefit of their employees); plus 

(z) an amount equal to the sum of (I) 100% of the aggregate net proceeds (including the fair market value of property

time subsequent to December 14, 2010 such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that, in the case of item (II), the foregoing sum shall not exceed, in the case of any Unrestricted
Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary.

employees and other than Designated Preferred Stock) or a substantially concurrent cash capital contribution received by the Company from its stockholders; provided, however, that the net cash proceeds from such sale or such cash

pursuant to this clause (4) shall not exceed in any fiscal year the sum of (A) $25 million in any fiscal year carried over to succeeding fiscal years (with unused amounts (including $50.0 million remaining unused under the 2021 Notes) so
carrying over as of the Issue Date) subject to a maximum (without giving effect to the following clause (B)) of $50 million in any fiscal year plus (B) any amounts not utilized in any preceding fiscal year following

clause (2) of this paragraph and by the cash proceeds of any “key-man” life insurance policies which are used to make such redemptions or repurchases); provided, further, that the cancellation of Indebtedness owing
to the Company from members of management of the Company or any of its Restricted Subsidiaries in connection with any repurchase of Capital Stock of such entities (or warrants or options or rights to acquire such Capital Stock) will not be deemed to
constitute a Restricted Payment under this Indenture;

 (11) the
repayment or extension of intercompany debt that is permitted under the Indenture; 

  
 45 








 (12) cash payments in lieu of fractional shares in connection with the

(13) upon occurrence of a Change of Control, and within 60 days after the completion of the Change of Control Offer
pursuant to Section 4.15 hereof (including the purchase of all Notes tendered), any purchase or redemption of Obligations of the Company that are subordinate or junior in right of payment to the Notes required pursuant to the terms thereof as a
result of such Change of Control at a purchase or redemption price not to exceed 101% of the outstanding principal amount thereof, plus accrued and unpaid interest thereon, if any; provided, however, that (A) at the time of such
purchase or redemption, no Default or Event of Default shall have occurred and be continuing (or would result therefrom) and (B) such purchase or redemption is not made, directly or indirectly, from the proceeds of (or made in anticipation of)
any issuance of Indebtedness by the Company or any Subsidiary; and 
 (14) Restricted Payments that are made with Excluded
Contributions. 
 Notwithstanding any of the foregoing to the contrary, the Company and its Restricted Subsidiaries may make any Restricted
Payment so long as (1) no Default or Event of Default has occurred and is continuing and (2) at the time of such Restricted Payment and after giving pro forma effect thereto, the Company’s Consolidated Fixed Charge Coverage Ratio
would exceed 2.0 to 1.0; provided, however, that if, at any time the criteria set forth in the preceding clause (2) cease to be satisfied, all Restricted Payments made by the Company or any of its Restricted Subsidiaries occurring on or
after the date on which such criteria ceased to be satisfied shall be required to be made, to the extent permitted thereby, in compliance with the preceding paragraphs of this covenant, and the amount available for Restricted Payments pursuant to
clause (ii) of the first paragraph of this covenant on or after the date on which such criteria ceases to be satisfied shall be equal to the amount that would have been available for Restricted Payments pursuant to such clause (ii) on such
date without giving effect to any Restricted Payments made through such date pursuant to and in compliance with this paragraph; provided, further, that, if the Company or any of its Restricted Subsidiaries become contractually obligated to
make any Restricted Payment at the time criteria set forth in the preceding clauses (1) and (2) continues to be satisfied, then the Company or such Restricted Subsidiary, as the case may be, may continue to make such Restricted Payments,
even if the criteria in such clauses (1) and (2) ceases to be satisfied at the time such Restricted Payment is actually made, notwithstanding the limitation set forth in the preceding proviso, and the amount available for Restricted
Payments pursuant to clause (ii) of the first paragraph of this covenant on or after the date on which such criteria ceases to be satisfied shall be equal to the amount that would have been available for Restricted Payments pursuant to such
clause (ii) on such date without giving effect to any Restricted Payments made on such date pursuant to and in compliance with this proviso. 

For purposes of determining compliance with this covenant, in the event that a payment or other action meets the criteria of more than one of
the exceptions described in clauses (1) through (14) above, or is permitted to be made pursuant to clause (ii) of the first paragraph of this covenant (including by virtue of qualifying as a Permitted Investment), the


  
 46 








 
Company will be permitted to classify such payment or other action on the date of its occurrence in any manner that complies with this covenant. Payments or other actions permitted by this
covenant need not be permitted solely by reference to one provision permitting such payment or other action but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such payment or
other action (including pursuant to any section of the definition of “Permitted Investments”). 
 The Board of Directors of the
Company may designate any Restricted Subsidiary of the Company to be an Unrestricted Subsidiary as specified in the definition of “Unrestricted Subsidiary”. For purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time of the designation and shall reduce the amount available for Restricted Payments
under the first paragraph of this Section 4.07. All of those outstanding Investments shall be deemed to constitute Investments in an amount equal to the fair market value of the Investments at the time of such designation. Such designation
shall only be permitted if the Restricted Payment would be permitted at the time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 

SECTION 4.08. Dividend and Other Payment Restrictions Affecting Subsidiaries. 

The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Company to: (a) pay dividends or make any other distributions on, or in respect of, its Capital
Stock; (b) make loans or advances or pay any Indebtedness or other obligation owed to the Company or any Guarantor; or (c) transfer any of its property or assets to the Company or any Guarantor, except, with respect to clauses (a),
(b) and (c), for such encumbrances or restrictions existing under or by reason of: (1) applicable law, rule, regulation or order; (2) this Indenture, the Notes, the 2018 Notes, the 2020 Notes, thte 2021 Notes, the 2022 Notes and the
Guarantees; (3) non-assignment provisions of any contract or any lease of any Restricted Subsidiary of the Company entered into in the ordinary course of business; (4) any instrument governing Acquired Indebtedness, which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; (5) the Credit Facilities as entered into or existing on the Issue Date or any
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that any restrictions imposed pursuant to any such amendment, modification; restatement, renewal, increase,
supplement, refunding, replacement or refinancing are ordinary and customary with respect to syndicated bank loans (under the relevant circumstances); (6) agreements existing on the Issue Date to the extent and in the manner such agreements are
in effect on the Issue Date; (7) restrictions on the transfer of assets subject to any Lien permitted under this Indenture imposed by the holder of such Lien; (8) restrictions imposed by any agreement to sell assets or Capital Stock
permitted under this Indenture to any Person pending the closing of such sale; (9) any agreement or instrument governing Capital Stock of any Person that is acquired; (10) any Purchase Money Note or other Indebtedness or other contractual
requirements of a Securitization Entity in connection with a 

  
 47 








 
Qualified Securitization Transaction; provided that such restrictions apply only to such Securitization Entity; (11) other Indebtedness or Permitted Subsidiary Preferred Stock
outstanding on the Issue Date or permitted to be issued or incurred under this Indenture; provided that any such restrictions are ordinary and customary with respect to the type of Indebtedness being incurred or Preferred Stock being issued
(under the relevant circumstances); (12) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; (13) any encumbrances or restrictions imposed by any
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (4) and (6) through (12) above;
provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company’s Board of Directors (evidenced by a Board Resolution)
whose judgment shall be conclusively binding, not materially more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification,
restatement, renewal, increase, supplement, refunding, replacement or refinancing; (14) customary provisions in joint venture, partnership, asset sale, sale leaseback and other similar agreements; and (15) customary provisions in leases
and other agreements entered into in the ordinary course of business. 
 SECTION 4.09. Incurrence of Indebtedness. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, “incur”) any Indebtedness (other than Permitted Indebtedness); provided, however, that the
Company and any Restricted Subsidiary may incur Indebtedness (including Acquired Indebtedness), in each case if, on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge
Coverage Ratio of the Company would have been greater than 2.0 to 1.0; provided, however, that the amount of Indebtedness (including Acquired Indebtedness) that may be incurred pursuant to the foregoing by Restricted Subsidiaries that are not
Guarantors shall not exceed $100 million at any one time outstanding. 
 SECTION 4.10. Asset Sales. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Company or the
applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets sold or otherwise disposed of (as determined in good faith by the Company);
(ii) at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of cash or Cash Equivalents; provided that the amount of: 

(a) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto,
or if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been shown on the Company’s or such Restricted Subsidiary’s balance or the footnotes thereto if such incurrence or accrual had taken
place on the date of such balance 

  
 48 








 
sheet, as determined by the Company) of the Company or any such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee
of any such assets; (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 180 days of the
receipt thereof (to the extent of the cash received); and (c) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value, taken together with all
other Designated Non-cash Consideration received pursuant to this clause (c) after December 14, 2010 that is at that time outstanding, not to exceed the greater of $150 million and 5% 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), shall, in each of (a), (b) and
(c) above, be deemed to be cash for the purposes of this provision or for purposes of the second paragraph of this Section 4.10; and 

(iii) upon the consummation of an Asset Sale, the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to
such Asset Sale within 545 days of receipt thereof either 
 (A) to prepay any Senior Debt or Indebtedness of a Restricted Subsidiary that
is not a Guarantor and, in the case of any such Indebtedness under any revolving credit facility, effect a corresponding reduction in the availability under such revolving credit facility (or effect a permanent reduction in the availability under
such revolving credit facility regardless of the fact that no prepayment is required in order to do so (in which case no prepayment should be required)), 

(B) to reinvest in Productive Assets (provided that this requirement shall be deemed satisfied if the Company or such Restricted
Subsidiary, by the end of such 545-day period, has entered into a binding agreement under which it is contractually committed to reinvest in Productive Assets, and such investment is consummated within 120 days from the date on which such binding
agreement is entered into, and, with respect to the amount of such investment, the reference to the 546th day after an Asset Sale in the second following sentence shall be deemed to be a reference to the 121st day after the date on which such
binding agreement is entered into (but only if such 121st day occurs later than such 546th day)) or 
 (C) a combination of prepayment and
investment permitted by the foregoing clauses (iii)(A) and (iii)(B). 
 Pending the final application of any such Net Cash Proceeds, the Company or
such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents. On the 546th day after an Asset Sale or such earlier date, if any, as the Board
of Directors of the Company or of such Restricted Subsidiary determines by Board Resolution not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (iii)(A), (iii)(B) and (iii)(C) of the next preceding
sentence 

  
 49 








 
(each, a “Net Proceeds Offer Trigger Date”), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted
in clauses (iii)(A), (iii)(B) and (iii)(C) of the next preceding sentence (each a “Net Proceeds Offer Amount”) shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the “Net
Proceeds Offer”) on a date (the “Net Proceeds Offer Payment Date”) not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, from all Holders and holders of any other Senior
Subordinated Debt of the Company or a Restricted Subsidiary of the Company requiring the making of such an offer, on a pro rata basis, the maximum amount of Notes and such other Senior Subordinated Debt that may be purchased with the Net
Proceeds Offer Amount at a price equal to 100% of their principal amount (or, in the event such other Senior Subordinated Debt was issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest
thereon, if any, to the date of purchase (or, in respect of such other Senior Subordinated Debt, such lesser price, if any, as may be provided for by the terms of such Senior Subordinated Debt); provided, however, that if at any time
any non-cash consideration (including any Designated Non-cash Consideration) received by the Company or any Restricted Subsidiary of the Company, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed
of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder, and the Net Cash Proceeds thereof shall be applied in accordance
with this Section 4.10. Notwithstanding the foregoing, if a Net Proceeds Offer Amount is less than $40.0 million, the application of the Net Cash Proceeds constituting such Net Proceeds Offer Amount to a Net Proceeds Offer may be deferred
until such time as such Net Proceeds Offer Amount plus the aggregate amount of all Net Proceeds Offer Amounts arising subsequent to the Net Proceeds Offer Trigger Date relating to such initial Net Proceeds Offer Amount from all Asset Sales by the
Company and its Restricted Subsidiaries aggregates to at least $40.0 million, at which time the Company or such Restricted Subsidiary shall apply all Net Cash Proceeds constituting all Net Proceeds Offer Amounts that have been so deferred to make a
Net Proceeds Offer (the first date the aggregate of all such deferred Net Proceeds Offer Amounts is equal to $40.0 million or more shall be deemed to be a Net Proceeds Offer Trigger Date). 

Notwithstanding the immediately preceding paragraph, the Company and its Restricted Subsidiaries shall be permitted to consummate an Asset
Sale without complying with such paragraph to the extent that: (i) at least 75% of the consideration for such Asset Sale constitutes Productive Assets, cash, Cash Equivalents and/or Marketable Securities; and (ii) such Asset Sale is for
fair market value (as determined in good faith by the Company); provided that any consideration consisting of cash, Cash Equivalents and/or Marketable Securities received by the Company or any of its Restricted Subsidiaries in connection with
any Asset Sale permitted to be consummated under this paragraph shall constitute Net Cash Proceeds subject to the provisions of the preceding paragraph. 

Notice of each Net Proceeds Offer will be sent to DTC, in the case of Global Notes, or mailed to the record Holders as shown on the register
of Holders, in the case of certificated notes, within 30 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in Section 3.09 hereof. To the extent that the aggregate
amount of Notes and other Senior Subordinated Debt tendered pursuant to a Net Proceeds Offer is less than the Net Proceeds Offer Amount, the Company may use any 

  
 50 








 
remaining Net Proceeds Offer Amount for general corporate purposes or for any other purpose not prohibited by this Indenture. Upon completion of any such Net Proceeds Offer, the Net Proceeds
Offer Amount shall be reset at zero. 
 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 such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue thereof.

 SECTION 4.11. Transactions with Affiliates. 

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to occur
any transaction or series of related transactions (including the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (an “Affiliate Transaction”) involving
aggregate payment or consideration in excess of $20.0 million unless (i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that might reasonably have
been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company; and (ii) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate payments or consideration in excess of $30.0 million, a Board Resolution adopted by the majority of the members of the Board of Directors of the Company approving such Affiliate Transaction and an
officers’ certificate certifying that such Affiliate Transaction complies with clause (i) above. 
 (b) The restrictions set forth
in Section 4.11(a) hereof shall not apply to: (i) reasonable fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary of the Company
as determined in good faith by the Company’s Board of Directors or senior management; (ii) transactions between or among the Company and any of its Restricted Subsidiaries or between or among such Restricted Subsidiaries, provided
that such transactions are not otherwise prohibited by this Indenture; (iii) any agreement as in effect as of the Issue Date or any amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto) or by
any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders in any material respect than the original agreement as in effect on the Issue Date as determined in good faith by the
Company; (iv) Restricted Payments or Permitted Investments permitted by this Indenture; (v) transactions effected as part of a Qualified Securitization Transaction; (vi) payments or loans to employees or consultants that are approved
by the Board of Directors of the Company in good faith; (vii) sales of Qualified Capital Stock; (viii) the existence of, or the performance by the Company or any of its Restricted Subsidiaries of its obligations under the terms of, any
stockholders’ agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter; provided,
however, that the existence of, or the performance 

  
 51 








 
by the Company or any of its Restricted Subsidiaries of obligations under, any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date
shall only be permitted by this clause (viii) to the extent that the terms of any such amendment or new agreement taken as a whole are not materially disadvantageous to the Holders; (ix) transactions permitted by, and complying with, the
provisions of Article 5 hereof, (x) any issuance of securities or other payments, awards, grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans approved by
the Board of Directors of the Company; and (xi) transactions in which the Company or any Restricted Subsidiary, as the case may be, receives an opinion from a nationally recognized investment banking, appraisal or accounting firm that such
Affiliate Transaction is either fair, from a financial standpoint, to the Company or such Restricted Subsidiary or is on terms not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time
on an arm’s length basis from a Person that is not an Affiliate of the Company. 
 SECTION 4.12. Liens. 

The Company shall not, and shall not cause or permit any Guarantor to, incur any Secured Debt that is not Senior Debt of such Person unless,
contemporaneously therewith, such Person makes effective provision to secure the Notes or the relevant Guarantee, as applicable, equally and ratably with such Secured Debt for so long as such Secured Debt is secured by a Lien (the “Initial
Lien”). Any Lien created for the benefit of the Holders pursuant to the preceding sentence shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the
Lien securing the other Secured Debt and that holders of such other Secured Debt may exclusively control the disposition of property subject to the Initial Lien. 

SECTION 4.13. Conduct of Business. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, engage in any businesses a majority of whose revenues are
not derived from businesses that are the same or reasonably similar, ancillary or related to, or a reasonable extension, development or expansion of, the businesses in which the Company and its Restricted Subsidiaries are engaged on the Issue Date
(which shall include engineered components businesses not within the aerospace industry). 
 SECTION 4.14. Corporate Existence. 

Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect
(i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or
any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided, however, that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the


  
 52 








 
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 of the Notes. 

SECTION 4.15. Offer to Repurchase upon Change of Control. 

(a) If a Change of Control occurs, each Holder shall have the right to require that the Company purchase all or a portion of such
Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at a purchase price equal to 101% of the principal amount thereof plus accrued interest to the date of purchase. Within 30 days following
the date upon which the Change of Control occurred, the Company must send, in the case of Global Notes, through the facilities of DTC and, in the case of certificated notes, by first class mail, a notice to the Trustee and each Holder, which notice
shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent or mailed, other than as may be
required by law (the “Change of Control Payment Date”). Holders electing to have a Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date. 

(b) On the Change of Control Payment Date, the Company shall, to the extent lawful, (1) accept for payment all Notes or portions thereof
properly tendered pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an amount equal to the Change of Control payment in respect of all Notes or portions thereof so tendered and (3) deliver or cause to be delivered
to the applicable Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of
Notes so tendered the Change of Control payment for such Notes, and the Trustee shall promptly authenticate and mail or deliver (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof. The Company shall publicly announce the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date. 
 Prior to the mailing of the notice referred to in
Section 4.15(a) above, but in any event within 30 days following any Change of Control, the Company shall: (i) repay in full all Indebtedness under the Credit Facilities and all other Senior Debt the terms of which require repayment
upon a Change of Control; or (ii) obtain the requisite consents under the Credit Facilities and all such other Senior Debt to permit the repurchase of the Notes as provided below. The Company’s failure to comply with the covenant described
in the immediately preceding sentence shall constitute an Event of Default described in clause (c) and not in clause (b) under Section 6.01 hereof. 

(c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act to the extent such laws and regulations are
applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the Company 

  
 53 








 
complies with the provisions of any such securities laws or regulations, the Company shall not be deemed to have breached its obligations under this Section 4.15. 

(d) Notwithstanding anything to the contrary in this Section 4.15, the Company shall not be required to make a Change of Control Offer
upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 hereof and purchases all Notes validly tendered
and not withdrawn under such Change of Control Offer or (2) a notice of redemption has been given pursuant to Section 3.03 hereof prior to the date on which notice of the Change of Control Offer must be sent. 

A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of Control occurring, if a
definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. 
 SECTION 4.16. No Senior
Subordinated Debt. 
 The Company shall not, and shall not permit any Guarantor to, incur or suffer to exist Indebtedness that is senior
in right of payment to the Notes or such Guarantor’s Guarantee, as the case may be, and subordinate in right of payment to any other Indebtedness of the Company or such Guarantor, as the case may be. For the avoidance of doubt, unsecured
Indebtedness is not subordinated or junior to Secured Debt merely because it is unsecured. 
 SECTION 4.17. Additional Guarantees.

 The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create or acquire another Domestic Restricted
Subsidiary unless such Domestic Restricted Subsidiary within 20 Business Days executes and delivers a supplemental indenture to the Indenture, providing for a senior subordinated guarantee of payment of the Notes by such Domestic Restricted
Subsidiary; provided, however, that such Domestic Restricted Subsidiary need not execute and deliver such a supplemental indenture for so long as such Domestic Restricted Subsidiary is an Immaterial Domestic Restricted Subsidiary;
provided further, however, that the Company will cause a Domestic Restricted Subsidiary that was an Immaterial Domestic Restricted Subsidiary but has ceased to qualify as an Immaterial Domestic Restricted Subsidiary to execute and deliver a
supplemental indenture to the Indenture, providing for a senior subordinated guarantee of payment of the Notes by such Domestic Restricted Subsidiary no later than 20 Business Days after the end of the most recently ended fiscal quarter of the
Company in which such Domestic Restricted Subsidiary ceased to be an Immaterial Domestic Restricted Subsidiary; provided further, however, that, if at any time, Domestic Restricted Subsidiaries that are not Guarantors because they are
Immaterial Domestic Restricted Subsidiaries constitute in the aggregate more than 5% of Total Assets as of the end of the most recently ended fiscal quarter of the Company for which financial statements are available or more than 5% of Consolidated
EBITDA of the Company for the period of four consecutive fiscal quarters as of the end of the most recently ended fiscal quarter of the Company for which financial statements are available, then the Company shall cause one or more such Domestic
Restricted Subsidiaries to become Guarantors (notwithstanding that such Domestic Restricted Subsidiaries are, individually, Immaterial Domestic Restricted Subsidiaries), no later than 20 

  
 54 








 
Business Days after the end of the most recently ended fiscal quarter in which such requirement was triggered, such that the foregoing condition ceases to be true. 

SECTION 4.18. Limitation on Preferred Stock of Restricted Subsidiaries. 

The Company shall not permit any of its Restricted Subsidiaries to issue any Preferred Stock (other than to the Company or to a Restricted
Subsidiary of the Company) or permit any Person (other than the Company or a Restricted Subsidiary of the Company) to own any Preferred Stock of any Restricted Subsidiary of the Company, other than Permitted Subsidiary Preferred Stock. The
provisions of this Section 4.18 will not apply to (w) any of the Guarantors, (x) any transaction as a result of which neither the Company nor any of its Restricted Subsidiaries will own any Capital Stock of the Restricted Subsidiary
whose Preferred Stock is being issued or sold and (y) Preferred Stock that is Disqualified Capital Stock and is issued in compliance with Section 4.09 hereof. 

SECTION 4.19. Suspension of Covenants. 

(a) During any period of time following 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 the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the
Company and its Restricted Subsidiaries shall not be subject to the following provisions of the Indenture: 
 (1)
Section 4.07; 
 (2) Section 4.08; 

(3) Section 4.09; 

(4) Section 4.10; 

(5) Section 4.11; 

(6) Section 4.13; 

(7) Section 4.16; 

(8) Section 4.17; 

(9) Section 4.18; and 

(10) clause (ii) of the first paragraph of Section 5.01 

(collectively, the “Suspended Covenants”). Upon the occurrence of a Covenant Suspension Event, the amount of Net Cash Proceeds with respect
to any applicable Net Proceeds Offer Trigger Date shall be set at zero at such date (the “Suspension Date”). In addition, in the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for
any period of time as a result of the foregoing, and, on any subsequent date (the “Reversion 

  
 55 








 
Date”), one or both of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Notes below an Investment Grade Rating, or a Default or Event
of Default occurs and is continuing, then the Company and the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants with respect to future events. The period of time between the Suspension Date and the Reversion Date
is referred to in this description as the “Suspension Period.” Within 30 days of the Reversion Date, any Restricted Subsidiary that would have been required during the Suspension Period but for the Suspended Covenants by
Section 4.17 to execute a supplemental indenture shall execute such supplemental indenture required by such covenant. Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred
as a result of a failure to comply with the Suspended Covenants during the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that occurred during the Suspension Period). 

(b) On the Reversion Date, all Indebtedness incurred during the Suspension Period will be classified to have been incurred or issued pursuant
to Section 4.09 to the extent such Indebtedness would be permitted to be incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness incurred or issued prior to the Suspension Period and outstanding on the
Reversion Date. To the extent such Indebtedness would not be so permitted to be incurred or issued pursuant to Section 4.09, such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted
under clause (b) of the definition of Permitted Indebtedness. Restricted Payments made during the Suspension Period will be deemed to have been made pursuant to the first paragraph of Section 4.07. 

(c) If (i) a Change of Control occurs that results in either (a) the sale, lease, exchange or other transfer of all or substantially
all of the assets of the Company to any Person or Group (as defined in the definition of Change of Control) other than an Affiliate (other than a Person that becomes an Affiliate solely as a result of such transaction) of the Company or (b) any
Person or Group other than an Affiliate (other than a Person that becomes an Affiliate solely as a result of such transaction) of the Company becomes the beneficial owner, directly or indirectly, of shares representing 100% of the total ordinary
voting power represented by the issued and outstanding Capital Stock of the Company or Holdings and (ii) such Person or Group acquiring control pursuant to clause (i) above is subject to the reporting requirements of Section 13 or
15(d) of the Exchange Act, then the Company shall not be subject to Section 4.03(a) from that time if and for so long as such Person or Group maintains Investment Grade Ratings from both Rating Agencies. 

(d) The Company shall give the Trustee prompt (and in any event not later than five Business Days after a Covenant Suspension Event) written
notice of any Covenant Suspension Event. In the absence of such notice, the Trustee shall assume the Suspended Covenants apply and are in full force and effect. The Company shall give the Trustee prompt (and in any event not later than five Business
Days after a Covenant Suspension Event) written notice of any occurrence of a Reversion Date. After any such notice of the occurrence of a Reversion Date, the Trustee shall assume the Suspended Covenants apply and are in full force and effect.

satisfied.

effect that the Company will comply with its obligations under Section 4.10 hereof in respect of such disposition) the resulting, surviving or transferee Person (if not such Guarantor) shall be a Person organized and validly existing under the
laws of the jurisdiction under which such Guarantor was organized or under the laws of the United States of America, any State thereof or the District of Columbia, and such Person shall expressly assume, by a supplemental indenture (in form and
substance satisfactory to the Trustee), executed and delivered to the Trustee, all the obligations of such Guarantor, if any, under its Guarantee; 

  

	 	(2)	except in the case of a merger of such Guarantor with or into the Company or another Guarantor of the Company, and except in the case of a merger entered into solely for the purpose of reincorporating such Guarantor in
another jurisdiction, immediately after giving effect to such transaction and the assumption contemplated by the immediately preceding clause (b)(1) (including giving effect to any Indebtedness and Acquired Indebtedness incurred and any Lien

	 	(1)	 the resulting, surviving or transferee Person (if not Holdings) shall be a Person organized and validly existing under the laws of the United States
of America, any State thereof or the District of Columbia, and such Person shall expressly assume, by a supplemental indenture (in form and 



  
 58 









	 	
substance satisfactory to the Trustee), executed and delivered to the Trustee, all the obligations of Holdings, if any, under its Guarantee; 


 

	 	(2)	except in the case of a merger entered into solely for reincorporating Holdings in another jurisdiction, immediately after giving effect to such transaction and the assumption contemplated by the immediately preceding
clause (c)(1) (including giving effect to any Indebtedness and Acquired Indebtedness incurred and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred and be continuing; and


  

	 	(3)	the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition
and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with the applicable provisions of this Indenture and that all conditions precedent in the Indenture relating to such transaction
have been satisfied. 

 In case of any such consolidation, merger, sale or conveyance, and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture
to be performed by the Restricted Subsidiary, such successor Person shall succeed to and be substituted for the Restricted Subsidiary with the same effect as if it had been named herein as a Restricted Subsidiary. Such successor Person thereupon may
cause to be signed any or all of the Guarantees of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof. 

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of
all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Company, the Capital Stock of which constitutes all or substantially all of the properties and assets of the Company, shall be deemed to be the
transfer of all or substantially all of the properties and assets of the Company. However, transfer of assets between or among the Company and its Restricted Subsidiaries will not be subject to this Section 5.01. 

SECTION 5.02. Successor Corporation Substituted. 

Upon any consolidation, combination or merger, or any transfer of all or substantially all of the assets of the Company in accordance with
Section 5.01 hereof, in which the Company is not the continuing corporation, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, lease or transfer is made shall succeed to, and be
substituted for, and may exercise every right and power 

  
 59 








 
of the Company under this Indenture and the Notes with the same effect as if such surviving entity had been named as such and that, in the event of a conveyance or transfer (but not a lease), the
conveyor or transferor (but not a lessor) shall be released from the provisions of this Indenture. 
 ARTICLE VI 

DEFAULTS AND REMEDIES 

SECTION 6.01. Events of Default. 

“Event of Defaults” are: 

(a) the failure to pay interest on any Notes when the same becomes due and payable if the default continues for a period of 30
days (whether or not such payment shall be prohibited by Article 10 or Article 12 hereof); 
 (b) the failure to
pay the principal on any Notes when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer
on the date specified for such payment in the applicable offer to purchase) (whether or not such payment shall be prohibited by Article 10 or Article 12 hereof); 

(c) a default in the observance or performance of any other covenant or agreement contained herein if the default continues for
a period of 60 days (or 180 days in the case of the covenant described under Section 4.03 hereof) after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of
at least 25% of the outstanding principal amount of the Notes (except in the case of a default with respect to Section 5.01 hereof, which will constitute an Event of Default with such notice requirement but without such passage of time
requirement); 
 (d) the failure to pay at final stated maturity (giving effect to any applicable grace periods and any
extensions thereof) the principal amount of any Indebtedness of the Company or any Significant Subsidiary of the Company (other than a Securitization Entity), or the acceleration of the final stated maturity of any such Indebtedness, if the
aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated, aggregates $50.0 million or more at any time;

 (e) one or more judgments in an aggregate amount in excess of $50.0 million shall have been rendered against the
Company or any of its Significant Subsidiaries and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable; 

  
 60 








 (f) the Company or any of its Significant Subsidiaries pursuant to, or within the
meaning of, Bankruptcy Law: 
 (i) commences a voluntary case, 

(ii) consents to the entry of an order for relief against it in an involuntary case, 

(iii) consents to the appointment of a custodian of it or for all or substantially all of its property, or 

(iv) makes a general assignment for the benefit of its creditors, or 

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

(i) is for relief against the Company or any of its Significant Subsidiaries; 

(ii) appoints a custodian of the Company or any of its Significant Subsidiaries or for all or substantially all of the property
of the Company or any of its Significant Subsidiaries; or 
 (iii) orders the liquidation of the Company or any of its
Significant Subsidiaries; 
 (iv) and the order or decree remains unstayed and in effect for 60 consecutive days. 

SECTION 6.02. Acceleration. 

If any Event of Default (other than an Event of Default specified in clause (f) or (g) of Section 6.01 hereof with respect to
the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare the principal of, and accrued interest on, all the Notes to be due and payable immediately by notice in
writing to the Company and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration” (the “Acceleration Notice”), and the same (i) shall become immediately due and payable or
(ii) if there are any amounts outstanding under the Credit Facilities, shall become immediately due and payable upon the first to occur of an acceleration under the Credit Facilities or five Business Days after receipt by the Company and the
Representative under the Credit Facilities of such Acceleration Notice but only if such Event of Default is then continuing. If an Event of Default specified in clause (f) or (g) of Section 6.01 hereof with respect to the Company
occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on, all the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holder. 
 At any time after a declaration of acceleration with respect to the Notes as described in the
preceding paragraph, the Holders of a majority in principal amount of the Notes 

  
 61 








 
may rescind and cancel such declaration and its consequences (i) if the rescission would not conflict with any judgment or decree, (ii) if all existing Events of Default have been cured
or waived except nonpayment of principal or interest that has become due solely because of the acceleration, (iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which
has become due otherwise than by such declaration of acceleration, has been paid, (iv) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and (v) in the
event of the cure or waiver of an Event of Default of the type described in clause (f) or (g) of Section 6.01 hereof, 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 Default or impair any right consequent thereto. 
 SECTION 6.03.
Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal, premium, if any, and 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 6.04. Waiver of Past Defaults. 

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

Holders of a majority in principal amount of the then-outstanding Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial
to the rights of other Holders or that may involve the Trustee in personal liability. 

  
 62 








 SECTION 6.06. Limitation on Suits. 

A Holder may pursue a remedy with respect to this Indenture or the Notes only if: 

(a) the Holder gives to the Trustee written notice of a continuing Event of Default; 

(b) the Holders of at least 25% in principal amount of the then-outstanding Notes make a written request to the Trustee to
pursue the remedy; 
 (c) such Holder or Holders offer and, if requested, provide to the Trustee indemnity satisfactory to
the Trustee against any loss, liability or expense; 
 (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of indemnity; and 
 (e) during such 60-day period, the
Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 

SECTION 6.07. Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and interest
on the Note, on or after the respective due dates expressed in the Note (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 6.08. Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01 (a) or (b) 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 amount of, premium and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

SECTION 6.09. Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other
obligor upon the Notes), its creditors or its property and shall be 

  
 63 








 
entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out
of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 6.10. Priorities. 

Any money collected by the Trustee pursuant to this Article, and any other money or property distributable in respect of the Company’s
obligations under this Indenture after an Event of Default, shall be applied in the following order: 
 First: to the
Trustee (including a predecessor Trustee), its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee (including a
predecessor Trustee) and the costs and expenses of collection; 
 Second: to Holders for amounts due and unpaid on the
Notes for principal amount, premium and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal amount, premium and interest, respectively; and 

Third: 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. 

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 does not apply 

  
 64 








 
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof or a suit by Holders of more than 10% in principal amount of the then-outstanding Notes. 

ARTICLE VII 
 TRUSTEE 

SECTION 7.01. Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this
Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions which are specifically provided for by any
provision herein to be provided to it, the Trustee shall examine the certificates and opinions which are specifically required to be delivered to the Trustee by any provision of this Indenture to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

misconduct, except that: 
 (i) this paragraph does not limit the effect of paragraphs (b) or (e) of this Section;

 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is

against any loss, liability or expense.

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.

(a) The Trustee may conclusively rely upon any document 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. The Trustee

faith and in reliance thereon.

(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 security or indemnity reasonably satisfactory to it 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 document, but the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at
the sole cost of the Company and 

  
 66 








 
shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

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

(i) The permissive right of the Trustee to take or refrain from taking any actions enumerated in this Indenture shall not be construed as a
duty. 
 (j) The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this
Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics;
riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority and governmental action. 

(k) Anything in this Indenture notwithstanding, in no event shall the Trustee be liable for special, indirect, punitive or consequential loss
or damage of any kind whatsoever (including but not limited to loss of profit), even if the Trustee has been advised as to the likelihood of such loss or damage and regardless of the form of action. 

(l) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized
at such time to take specified actions pursuant to this Indenture. 
 SECTION 7.03. Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign. The Registrar or any Paying Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 

SECTION 7.04. Trustee’s Disclaimer. 

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

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 or any other document in connection with the sale of the Notes or pursuant to this Indenture
other than its certificate of authentication. 

  
 67 








 SECTION 7.05. Notice of Defaults. 

(a) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of such a Default or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. 

(b) Within 90 days after the occurrence of a Default or an Event of Default, the Trustee shall mail to Holders, as their names and addresses
appear in the security register for the Notes, a notice of the Default or Event of Default known to the Trustee, unless such Default or Event of Default shall have been cured or waived. 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 a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders. 

SECTION 7.06. Reports by Trustee to Holders of the Notes. 

Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, 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)(2). 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 SEC and each stock exchange
on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on, or delisted from, any stock exchange. 

The Trustee shall not be deemed to have any actual or constructive notice or knowledge of any reports or notice received from the Company,
Holdings or the Guarantors and subsequently provided to the Holders. 
 SECTION 7.07. Compensation and Indemnity. 

The Company, Holdings and the Guarantors shall, jointly and severally, pay to the Trustee from time to time such compensation for its
acceptance of this Indenture and services hereunder as the parties shall agree from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company, Holdings and the
Guarantors 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, Holdings and the Guarantors, jointly and severally,
shall indemnify the Trustee against any and all losses, claims, damages, liabilities or expenses (including reasonable attorneys’ fees and expenses) incurred by it arising out of, or in connection with, the acceptance or administration of its
duties under this Indenture, including the costs and 

  
 68 








 
expenses of enforcing this Indenture against the Company, Holdings and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company,
Holdings and the Guarantors 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, liability or expense shall be determined to have
been caused by its own negligence or willful misconduct. The Trustee shall notify the Company, Holdings and the Guarantors promptly of any claim of which a Responsible Offer has received notice for which it may seek indemnity. Failure by the Trustee
to so notify the Company shall not relieve the Company of its obligations hereunder. 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 such counsel. The Company, Holdings and the Guarantors need not pay for any settlement made without their consent, which consent shall not be unreasonably withheld. 

The obligations of the Company, Holdings and the Guarantors under this Section 7.07 shall survive the resignation or removal of the
Trustee, the satisfaction and discharge and the termination of this Indenture. 
 To secure the Company’s, Holdings’ and the
Guarantors’ payment obligations in this Section, 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 and interest on particular Notes. Such Lien
shall survive the resignation or removal of the Trustee, the satisfaction and discharge and the termination of this Indenture. 
 In
addition, and without prejudice to the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(f) or
(g) 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. 

“Trustee” for purposes of this Section shall include any predecessor Trustee and the Trustee in each of its capacities
hereunder and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee
hereunder. 
 The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable. 

SECTION 7.08. 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. 
 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 Notes 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:


  
 69 








 (a) the Trustee fails to comply with Section 7.10 hereof, 

(b) the Trustee is adjudged bankrupt or 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 

(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, at the expense of the Company, 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,
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 duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to 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 are subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s
obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 
 SECTION 7.09. Successor Trustee by
Merger, etc. 
 If the Trustee 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. 
 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, that is subject to supervision or examination by federal or state authorities and that has a combined
capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition. 

  
 70 








 This Indenture shall always have a Trustee who satisfies the requirements of TIA §
310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 SECTION 7.11. Preferential Collection of Claims Against
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.

SECTION 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time
elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 

SECTION 8.02. Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject
to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes 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 Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be
“outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all 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 solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal amount of, premium, if any, and interest on, such Notes
when such payments are due, (b) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder, and the
Company’s obligations in connection therewith, and (d) the provisions of this Article 8 with respect to Legal Defeasance. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section 8.03 hereof. 
 SECTION 8.03. Covenant Defeasance. 

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject
to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 

  
 71 








 
4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are
satisfied (hereinafter, “Covenant Defeasance”), and the Notes 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 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 6.01 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 8.01 hereof of the option applicable
to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(d) and 6.01(e) hereof shall not constitute Events of Default. 

SECTION 8.04. Conditions to Legal or Covenant Defeasance. 

The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: 

In order to exercise either Legal Defeasance or Covenant Defeasance: 

(a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States
dollars, non-callable Government Securities or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally-recognized firm of independent public accountants, to pay the principal amount at maturity of, premium and
interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be; 

(b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an Opinion of
Counsel in the United States of America reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture,
there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for
Federal income tax purposes as a result of such Legal Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of
Counsel in the United States of America reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for Federal income tax purposes as a result of


  
 72 








 
such Covenant Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not
occurred; 
 (d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than
a Default or Event of Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of which will be used to defease the Notes pursuant to this Article 8 concurrently with such incurrence and the grant of a Lien to
secure such Indebtedness) or, insofar as Section 6.01 (f) or 6.01(g) hereof is concerned, at any time in the period ending on the 91st day after the date of deposit; 

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under,
this Indenture (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing) or any other material agreement or instrument to which the Company or
any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (f) the Company shall have
delivered to the Trustee an Opinion of Counsel (which may be subject to customary exceptions) to the effect that (A) the trust funds will not be subject to any rights of holders of Senior Debt, including those arising under this Indenture, and
(B) after the 91st day following the deposit, the trust funds will not be subject to the effect of the preference provisions of Section 547 of the United States Federal Bankruptcy Code; 

(g) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; 

(h) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that
all conditions precedent provided for, or relating to, the Legal Defeasance or the Covenant Defeasance have been complied with; and 

(i) the Company shall have paid, or duly provided for payment of, all amounts then due to the Trustee pursuant to
Section 7.07 hereof. 
 Notwithstanding the foregoing, the Opinion of Counsel required by clause (b) above with respect to a Legal
Defeasance need not be delivered if all Notes not therefor delivered to the Trustee for cancellation (A) have become due and payable or (B) will become due and payable on the maturity date within one year under arrangements satisfactory to
the Trustee for giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 

  
 73 








 SECTION 8.05. Deposited Money and Government Securities to Be Held in Trust; Other
Miscellaneous Provisions. 
 Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect
of principal amount, 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 non-callable
Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the
request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally-recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(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 8.06. Satisfaction and Discharge. 

This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights or registration of transfer or
exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes when (i) either (a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or
paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation or
(b) all Notes not theretofore delivered to the Trustee for cancellation have (i) become due and payable, pursuant to an optional redemption notice or otherwise or (ii) will become due and payable within one year or are to be called
for redemption within one year, 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 on the Notes to the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as
the case may be; (ii) the Company has paid all other sums payable under this Indenture by the Company; and (iii) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions
precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with. 

  
 74 








 SECTION 8.07. Repayment to Company. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, for two years after such principal and premium, if any,
or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured 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 will be repaid to the Company. 

SECTION 8.08. Reinstatement. 

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with
Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or 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 8.09. Survival. 

The Trustee’s rights under this Article 8 shall survive termination of this Indenture or the resignation or removal of the Trustee.

 ARTICLE IX 
 Amendment,
Supplement and Waiver 
 SECTION 9.01. Without Consent of Holders of Notes. 

Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the
Guarantees or the Notes without the consent of any Holder: 
 (a) to cure any ambiguity, defect or inconsistency; 

(b) to provide for uncertificated Notes in addition to, or in place of, certificated Notes or to alter the provisions of
Article 2 or the Appendix hereof relating to the form of 

  
 75 








 
the Notes (including the related definitions) in a manner that does not materially adversely affect the legal rights of any Holder; 

(c) to provide for the assumption of the Company’s, Holdings’ or a Guarantor’s obligations to the Holders by a
successor to the Company, Holdings or a Guarantor pursuant to Article 5 or Article 11 hereof, 
 (d) to make any
change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights hereunder of any Holder; 

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

 (f) to provide for the issuance of Notes issued after the Issue Date in accordance with the limitations set forth in this
Indenture; 
 (g) to allow any Guarantor to execute a supplemental indenture and/or a Guarantee with respect to the Notes;
provided, however, that any such supplemental indenture and/or Guarantee need only be executed by the Company, such Guarantor and the Trustee; 

(h) to provide for the issuance of Exchange Notes or Private Exchange Notes; or 

(i) to conform the text of the Indenture, the Guarantees or the Notes to any provision of the Description of Notes to the
extent that such provision in the Description of Notes was intended to be a verbatim recitation of a provision of the Indenture, the Guarantees or the Notes. 

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company, Holdings and the Guarantors in the execution of any amended or supplemental Indenture authorized
or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise. 
 SECTION 9.02. With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, this Indenture (including Sections 3.09, 4.10 and 4.15 hereof), the Guarantees and the
Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except
a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Guarantees or the Notes may be waived with the consent of the Holders of a


  
 76 








 
majority in principal amount of the then-outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the
Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee
shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may, in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. 
 It shall not
be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any
provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 

(a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 

(b) reduce the principal of, or change or have the effect of changing, the fixed maturity of any Note, or change the date on
which any Note may be subject to redemption or reduce the redemption price therefor; 
 (c) reduce the rate of, or change or
have the effect of changing, the time for payment of interest, including defaulted interest, on any Note; 
 (d) waive a
Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount at maturity of the then
outstanding Notes and a waiver of the payment default that resulted from such acceleration); 
 (e) make any Notes payable in
money other than that stated in the Notes; 

  
 77 








 (f) make any change in the provisions of this Indenture protecting the right of
each Holder to receive payment of principal of and interest on such Note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of
Default; 
 (g) after the Company’s obligation to purchase Notes arises thereunder, amend, change or modify in any
material respect the obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control or modify any of the provisions or definitions with respect thereto after a Change of Control has occurred; 

(h) modify or change any provision of this Indenture or the related definitions affecting the subordination or ranking of the
Notes or the Guarantees in a manner which adversely affects the Holders; or 
 (i) make any change in the foregoing amendment
and waiver provisions. 
 An amendment under this Section may not make any change that adversely affects the rights under
Article 10 or 12 hereof or any supplemental indenture to this Indenture providing for a Guarantee of the Notes by a Restricted Subsidiary of the Company or any holder of Senior Debt of the Company, Holdings or of a Guarantor then outstanding
(including any such change of this paragraph of this Section 9.02) unless the holders of such Senior Debt (or their Representative) consent to such change. 

SECTION 9.03. 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 9.04. Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to
its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

 SECTION 9.05. Notation on, or Exchange of, Notes. 

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

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


  
 78 








 SECTION 9.06. Trustee to Sign Amendments, etc. 

The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does
not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the
Trustee shall be given and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
 ARTICLE X 

SUBORDINATION 
 SECTION
10.01. Agreement to Subordinate. 
 The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced
by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 10, to the prior payment of all Senior Debt of the Company and that the subordination is for the benefit of, and enforceable by, the
holders of such Senior Debt. The Notes shall in all respects rank pari passu with all other Senior Subordinated Debt of the Company, and only Indebtedness of the Company which is Senior Debt of the Company shall rank senior to the Notes in
accordance with the provisions set forth herein. All provisions of this Article 10 shall be subject to Section 10.12. 
 SECTION
10.02. Liquidation, Dissolution, Bankruptcy. 
 Upon any payment or distribution of the assets of the Company to creditors upon a
total or partial liquidation or a total or partial dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property: 

(1) holders of Senior Debt of the Company shall be entitled to receive payment in full in cash of such Senior Debt before
Holders shall be entitled to receive any payment; and 
 (2) until the Senior Debt of the Company is paid in full in cash,
any payment or distribution to which Holders would be entitled but for this Article 10 shall be made to holders of such Senior Debt as their interests may appear, except that Holders may receive shares of stock and any debt securities that are
subordinated to such Senior Debt to at least the same extent as the Notes. 
 SECTION 10.03. Default on Senior Debt of the Company.

 The Company shall not pay the principal of, premium, if any, or interest on the Notes or make any deposit pursuant to Section 8.04 and
may not purchase, redeem or otherwise retire any Notes (collectively, “pay the Notes”) if either of the following (a “Payment Default”) 

  
 79 








 
occurs: (1) any Designated Senior Debt of the Company is not paid in full in cash when due; or (2) any other default on Designated Senior Debt of the Company occurs, and the maturity of
such Designated Senior Debt is accelerated in accordance with its terms unless, in either case, the Payment Default has been cured or waived and any such acceleration has been rescinded or such Designated Senior Debt has been paid in full in cash;
provided, however, that the Company shall be entitled to pay the Notes without regard to the foregoing if the Company and the Trustee receive written notice approving such payment from the Representative of any Designated Senior Debt
with respect to which the Payment Default has occurred and is continuing. During the continuance of any default (other than a Payment Default) with respect to any Designated Senior Debt of the Company pursuant to which the maturity thereof may be
accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Company shall not pay the Notes for a period (a “Payment Blockage
Period”) commencing upon the receipt by the Trustee of (with a copy to the Company) written notice (a “Blockage Notice”) of such default from the Representative of such Designated Senior Debt specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment Blockage Period is terminated (1) by written notice to the Trustee and the Company from the Person or Persons
who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice is cured, waived or otherwise no longer continuing; or (3) because such Designated Senior Debt has been discharged or repaid in full in cash.
Notwithstanding the provisions described in the immediately preceding two sentences (but subject to the provisions contained in the first sentence of this Section), unless the holders of such Designated Senior Debt or the Representative of such
Designated Senior Debt shall have accelerated the maturity of such Designated Senior Debt, the Company shall be entitled to resume payments on the Notes after termination of such Payment Blockage Period. The Notes shall not be subject to more than
one Payment Blockage Period in any consecutive 360-day period, irrespective of the number of defaults with respect to Designated Senior Debt of the Company during such period; provided, however, that if any Blockage Notice within such
360-day period is given by or on behalf of any holders of Designated Senior Debt of the Company (other than the Bank Indebtedness), the Representative of the Bank Indebtedness shall be entitled to give another Blockage Notice within such period;
provided further, however, that in no event shall the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360-day consecutive period, and there
must be 181 days during any 360-day consecutive period during which no Payment Blockage Period is in effect. For purposes of this Section, no default or event of default which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Debt of the Company initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated
Senior Debt, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. 

SECTION 10.04. Acceleration of Payment of Notes. 

If payment of the Notes is accelerated because of an Event of Default, the Company or the Trustee shall promptly notify the holders of the
Designated Senior Debt of the Company (or their Representatives) of the acceleration. 

  
 80 








 SECTION 10.05. When Distribution Must Be Paid Over. 

If a distribution is made to Holders that, because of this Article 10, should not have been made to them, the Holders who receive the
distribution shall hold it in trust for holders of Senior Debt of the Company and pay it over to them as their interests may appear. If any Designated Senior Debt of the Company is outstanding, the Company shall not pay the Notes until five Business
Days after the Representatives of all the issues of Designated Senior Debt of the Company receive notice of such acceleration and, thereafter, shall be entitled to pay the Notes only if this Article 10 otherwise permits payment at that time.

 SECTION 10.06. Subrogation. 

After all Senior Debt of the Company is paid in full, and until the Notes are paid in full, Holders shall be subrogated to the rights of
holders of such Senior Debt to receive distributions applicable to such Senior Debt. A distribution made under this Article 10 to holders of such Senior Debt which otherwise would have been made to Holders is not, as between the Company and
Holders, a payment by the Company on such Senior Debt. 
 SECTION 10.07. Relative Rights. 

This Article 10 defines the relative rights of Holders and holders of Senior Debt of the Company. Nothing in this Indenture shall: 

(1) impair, as between the Company and Holders, the obligation of the Company, which is absolute and unconditional, to pay
principal of and interest on the Notes in accordance with their terms; or 
 (2) prevent the Trustee or any Holder from
exercising its available remedies upon a Default, subject to the rights of holders of Senior Debt of the Company to receive distributions otherwise payable to Holders. 

SECTION 10.08. Subordination May Not Be Impaired by Company. 

No right of any holder of Senior Debt of the Company to enforce the subordination of the Indebtedness evidenced by the Notes shall be impaired
by any act or failure to act by the Company or by its failure to comply with this Indenture. 
 SECTION 10.09. Rights of Trustee and
Paying Agent. 
 Notwithstanding anything in this Article 10, the Trustee or Paying Agent shall continue to make payments on the
Notes and shall not be charged with knowledge of the existence of facts that under this Article 10 would prohibit the making of any payments to or by the Trustee unless and until, not less than two Business Days prior to the date of such
payment, a Responsible Officer of the Trustee receives written notice satisfactory to it that such payments are prohibited by this Article 10. The Company, a Representative or a holder of Senior Debt of the Company shall be entitled to give the
notice; provided, however, that, if an issue of Senior Debt of the Company has a Representative, only the Representative shall be entitled to give the notice. Prior to the receipt of any such written notice, the Trustee shall be
entitled in all respects 

  
 81 








 
conclusively to presume that no such fact exists. Unless the Trustee shall have received the notice provided for in the preceding sentence, the Trustee shall have full power and authority to
receive such payment and to apply the same to the purpose for which it was received and shall not be affected by any notice to the contrary which may be received by it on or after such date. The foregoing shall not apply to any Affiliate of the
Company acting as Paying Agent. 
 The Trustee in its individual or any other capacity shall be entitled to hold Senior Debt of the Company
with the same rights it would have if it were not Trustee. The Registrar and the Paying Agent shall be entitled to do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 10 with respect to any
Senior Debt of the Company which may at any time be held by it, to the same extent as any other holder of such Senior Debt; and nothing in Article 7 shall deprive the Trustee of any of its rights as such holder. Notwithstanding anything in this
Article 10 to the contrary, all amounts owed to the Trustee (including amounts owed pursuant to Section 7.07 hereof) in each of its capacities hereunder shall not be subordinated to any Senior Debt of the Company or otherwise. 

SECTION 10.10. Distribution or Notice to Representative. 

Whenever any Person is to make a distribution or give a notice to holders of Senior Debt of the Company, such Person shall be entitled to make
such distribution or give such notice to their Representative (if any). 
 SECTION 10.11. Not to Prevent Events of Default or Limit Right
to Accelerate. 
 The failure to make a payment pursuant to the Notes by reason of any provision in this Article 10 shall not be
construed as preventing the occurrence of a Default. Nothing in this Article 10 shall have any effect on the right of the Holders or the Trustee to accelerate the maturity of the Notes. 

SECTION 10.12. Trust Moneys Not Subordinated. 

Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of Government Securities held in trust under
Article 8 hereof by the Trustee for the payment of principal of and interest on the Notes shall not be subordinated to the prior payment of any Senior Debt of the Company or subject to the restrictions set forth in this Article 10 if the
provisions of this Article 10 were not violated at the time funds were deposited in trust with the Trustee pursuant to Article 8 hereof, and none of the Holders shall be obligated to pay over any such amount to the Company or any holder of
Senior Debt of the Company or any other creditor of the Company. 
 SECTION 10.13. Trustee Entitled to Rely. 

Upon any payment or distribution pursuant to this Article 10, the Trustee, subject to Section 7.01, and the Holders shall be
entitled to rely (1) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 10.02 hereof are pending, (2) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the Holders or (3) upon the Representatives of Senior Debt of the Company for the purpose of ascertaining the Persons 

  
 82 








 
entitled to participate in such payment or distribution, the holders of such Senior Debt and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article 10. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Debt of the
Company to participate in any payment or distribution pursuant to this Article 10, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Debt held
by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 10, and, if such evidence is not furnished, the Trustee shall
be entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 7.01 and 7.02 hereof shall be applicable to all actions or omissions of actions by the
Trustee pursuant to this Article 10. 
 SECTION 10.14. Trustee to Effectuate Subordination. 

Each Holder by accepting a Note authorizes and directs the Trustee on its behalf to execute such documentation and to take such action as may
be necessary or appropriate to acknowledge or effectuate the subordination between the Holders and the holders of Senior Debt of the Company as provided in this Article 10 and appoints the Trustee as attorney-in-fact for any and all such
purposes. 
 SECTION 10.15. Trustee Not Fiduciary for Holders of Senior Debt of the Company. 

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of the Company and shall not be liable to any such
holders if it shall mistakenly pay over or distribute to Holders or the Company or any other Person, money or assets to which any holders of Senior Debt of the Company shall be entitled by virtue of this Article 10 or otherwise. With respect to
the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article and no implied covenants or obligations with respect to holders of Senior Debt shall
be read into this Indenture against the Trustee. 
 SECTION 10.16. Reliance by Holders of Senior Debt of the Company on Subordination
Provisions. 
 Each Holder, by accepting a Note, acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior Debt of the Company, whether such Senior Debt was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold,
such Senior Debt, and such holder of such Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Debt.

 ARTICLE XI 

Guarantees 
 SECTION
11.01. Guarantees. 
 Holdings and each Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of, and interest on, the Notes when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary
obligations of the Company under this Indenture and the Notes and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Notes (all the foregoing being
hereinafter collectively called the “Guaranteed Obligations”). Holdings and each Guarantor further agree that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from Holdings
or such Guarantor and that Holdings and such Guarantor will remain bound under this Article 11 notwithstanding any extension or renewal of any Guaranteed Obligation. 

Holdings and each Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations
and also waives notice of protest for nonpayment. Holdings and each Guarantor waive notice of any default under the Notes or the Guaranteed Obligations. The obligations of Holdings and each Guarantor hereunder shall not be affected by (a) the
failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of
any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Guaranteed
Obligations or any of them; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Obligations; or (f) except as set forth in Section 11.07, any change in the ownership of
Holdings or such Guarantor. 
 Holdings and each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment,
performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations. 

Each Guarantee is, to the extent and in the manner set forth in Article 12 hereof, subordinated and subject in right of payment to the
prior payment in full of the principal of and premium, if any, and interest on all Senior Debt of Holdings or such Guarantor, as the case may be, and each Guarantee is made subject to such provisions of this Indenture. 

Except as expressly set forth in Sections 11.02 and 11.07 hereof, the obligations of Holdings and each Guarantor hereunder shall not be
subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or 

  
 84 








 
unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of Holdings and each Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default,
failure or delay, willful or otherwise, in the performance of the obligations or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner, or to any extent, vary the risk of such Holdings or such
Guarantor or would otherwise operate as a discharge of Holdings or such Guarantor as a matter of law or equity. 
 Holdings and each
Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if, at any time, payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must
otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 
 In furtherance of
the foregoing, and not in limitation of any other right which any Holder or the Trustee has at law or in equity against Holdings or any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed
Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, Holdings and each Guarantor hereby promises to and shall, upon receipt
of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (1) the unpaid amount of such Guaranteed Obligations, (2) accrued and unpaid interest on such
Guaranteed Obligations (but only to the extent not prohibited by law) and (3) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee. 

Holdings and each Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Guaranteed Obligations until
payment in full of all Guaranteed Obligations and all obligations to which the Guaranteed Obligations are subordinated as provided in Article 12. Holdings and each Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the Guaranteed Obligations may be accelerated as provided in Article 6 for the purposes of Holdings’ or such Guarantor’s Guarantee herein, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations, and (y) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed
Obligations (whether or not due and payable) shall forthwith become due and payable by Holdings or such Guarantor for the purposes of this Section. 

Holdings and each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses)
incurred by the Trustee or any Holder in enforcing any rights under this Section. 
 SECTION 11.02. Limitation on Liability. 

Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Obligations guaranteed hereunder
by any Guarantor shall not 

  
 85 








 
exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally. 
 SECTION 11.03. Successors and Assigns. 

This Article 11 shall be binding upon Holdings and each Guarantor and its successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the Holders, and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically
extend to, and be vested in, such transferee or assignee, all subject to the terms and conditions of this Indenture. 
 SECTION 11.04. No
Waiver. 
 Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders
herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise. 

SECTION 11.05. Modification. 

No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by Holdings or any Guarantor
therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to, or demand
on, Holdings or any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

SECTION 11.06. [Intentionally Omitted]. 

SECTION 11.07. Release of Guarantor. 

Upon the sale (including any sale pursuant to any exercise of remedies by a holder of Senior Debt of the Company or of any Guarantor) or other
disposition (including by way of consolidation or merger) of a Guarantor or the sale or disposition of all or substantially all the assets of such Guarantor (in each case, other than a sale or disposition to the Company or an Affiliate of the
Company), or upon designation of a Guarantor as an Unrestricted Subsidiary pursuant to the terms of this Indenture, such Guarantor shall be deemed released from all obligations under this Article 11 without any further action required on the
part of the Trustee or any Holder. If the Guarantor becomes an Immaterial Domestic Restricted Subsidiary or ceases to be a Subsidiary or if the Company exercises its Legal Defeasance option or its Covenant Defeasance option in accordance with the
provisions of Article 8 hereof, or if its obligations under this Indenture are discharged in accordance with Section 8.06 hereof, Holdings and each Guarantor shall be released from all obligations under this Article 11 without any
further action required on the part of the Trustee or any Holder. At the request of the Company, the Trustee 

  
 86 








 
shall execute and deliver an appropriate instrument evidencing the release of a Guarantor pursuant to this Section 11.07. 

SECTION 11.08. Contribution. 

Holdings and each Guarantor that makes a payment under its Guarantee shall be entitled, upon payment in full of all Guaranteed Obligations, to
contribution from Holdings and each Guarantor, as applicable, in an amount equal to Holdings’ or such Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment
determined in accordance with GAAP (for purposes hereof, Holdings’ net assets shall be those of all its Consolidated Subsidiaries other than the Guarantors). 

ARTICLE XII 
 SUBORDINATION OF
GUARANTEES 
 SECTION 12.01. Agreement to Subordinate. 

Holdings and each Guarantor agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by Holdings’ or such
Guarantor’s Guarantee (as the case may be) is subordinated in right of payment, to the extent and in the manner provided in this Article 12, to the prior payment of all Senior Debt of Holdings or such Guarantor (as applicable) and that the
subordination is for the benefit of, and enforceable by, the holders of such Senior Debt. The Guaranteed Obligations of Holdings or a Guarantor (as applicable) shall in all respects rank pari passu with all other Senior Subordinated Debt of
Holdings or such Guarantor, and only Senior Debt of Holdings or such Guarantor (including Holdings’ or such Guarantor’s Guarantee of Senior Debt of the Company) shall rank senior to the Guaranteed Obligations of Holdings or such Guarantor
(as the case may be) in accordance with the provisions set forth herein. 
 SECTION 12.02. Liquidation, Dissolution, Bankruptcy. 

Upon any payment or distribution of the assets of Holdings or any Guarantor to creditors upon a total or partial liquidation or a total or
partial dissolution of Holdings or such Guarantor (as the case may be) or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to Holdings or such Guarantor (as the case may be) or its property: 

(1) holders of Senior Debt of Holdings or such Guarantor (as the case may be) shall be entitled to receive payment in full in
cash of such Senior Debt before Holders shall be entitled to receive any payment pursuant to the Guarantee of Holdings or such Guarantor (as the case may be); and 

(2) until the Senior Debt of Holdings or any Guarantor is paid in full in cash, any payment or distribution to which Holders
would be entitled but for this Article 12 shall be made to holders of such Senior Debt as their interests may appear, except that Holders may receive shares of stock and any debt securities of Holdings or such Guarantor (as the case may be)
that are subordinated to such Senior Debt to at least the same extent as its Guarantee. 

  
 87 








 SECTION 12.03. Default on Senior Debt of Guarantor. 

Neither Holdings nor any Guarantor shall make any payment on its Guarantee or purchase, redeem or otherwise retire or defease any Notes or
other Guaranteed Obligations (collectively, “pay its Guarantee”) if either of the following (a “Payment Default”) occurs (1) any Designated Senior Debt of Holdings or such Guarantor (as the case may be) is not
paid in full in cash when due; or (2) any other default on Designated Senior Debt of Holdings or such Guarantor (as the case may be) occurs, and the maturity of such Designated Senior Debt is accelerated in accordance with its terms; unless, in
either case, the Payment Default has been cured or waived and any such acceleration has been rescinded or such Designated Senior Debt has been paid in full in cash; provided, however, that Holdings or any Guarantor shall be entitled to
pay its Guarantee without regard to the foregoing if Holdings or such Guarantor (as the case may be) and the Trustee receive written notice approving such payment from the Representative of any Designated Senior Debt with respect to which the
Payment Default has occurred and is continuing. During the continuance of any default (other than a Payment Default) with respect to any Designated Senior Debt of Holdings or such Guarantor (as the case may be) pursuant to which the maturity thereof
may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, Holdings or such Guarantor (as the case may be) shall not pay its Guarantee
for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee of (with a copy to Holdings or such Guarantor (as the case may be)) written notice (a “Blockage Notice”) of such default from the
Representative of such Designated Senior Debt specifying an election to effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment Blockage Period is terminated (1) by
written notice to the Trustee and Holdings or such Guarantor (as the case may be) from the Person or Persons who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice is cured, waived or otherwise no longer
continuing; or (3) because such Designated Senior Debt has been discharged or repaid in full in cash. Notwithstanding the provisions described in the immediately preceding two sentences (but subject to the provisions contained in the first sentence
of this Section), unless the holders of such Designated Senior Debt giving such Payment Notice or the Representative of such Designated Senior Debt shall have accelerated the maturity of such Designated Senior Debt, Holdings or any Guarantor shall
be entitled to resume payments pursuant to its Guarantee after termination of such Payment Blockage Period. Neither Holdings nor any Guarantor shall be subject to more than one Blockage Period in any consecutive 360-day period, irrespective of the
number of defaults with respect to Designated Senior Debt of Holdings or such Guarantor (as the case may be) during such period; provided, however, that if any Blockage Notice within such 360-day period is given by, or on behalf, of
any holders of Designated Senior Debt of Holdings or such Guarantor (as the case may be) (other than the Bank Indebtedness), the Representative of the Bank Indebtedness shall be entitled to give another Blockage Notice within such period;
provided further, however, that in no event shall the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360-day consecutive period, and there
must be 181 days during any 360-day consecutive period during which no Payment Blockage Period is in effect. For purposes of this Section, no default or event of default which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Debt of Holdings or such Guarantor (as the case may be) initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the
Representative of 

  
 88 








 
such Designated Senior Debt, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than
90 consecutive days. 
 SECTION 12.04. Demand for Payment. 

If a demand for payment is made on Holdings or a Guarantor pursuant to Article 11 hereof, the Trustee shall promptly notify the holders
of the Designated Senior Debt of Holdings or such Guarantor (as the case may be) (or their Representatives) of such demand. 
 SECTION
12.05. When Distribution Must Be Paid Over. 
 If a distribution is made to Holders that, because of this Article 12, should not
have been made to them, the Holders who receive the distribution shall hold it in trust for holders of Senior Debt of Holdings or the applicable Guarantor (as the case may be) and pay it over to them or their Representatives as their interests may
appear. If any Designated Senior Debt of Holdings or a Guarantor is outstanding, Holdings or such Guarantor (as the case may be) shall not make a payment on its Guarantee until five Business Days after the Representatives of all the issuers of
Designated Senior Debt of Holdings or such Guarantor (as the case may be) receive notice of such acceleration and, thereafter, shall be entitled to pay the Notes only if this Article 12 otherwise permits payment at that time. 

SECTION 12.06. Subrogation. 

After all Senior Debt of Holdings or a Guarantor is paid in full, and until the Notes are paid in full, Holders shall be subrogated to the
rights of holders of such Senior Debt to receive distributions applicable to Senior Debt of Holdings or such Guarantor (as the case may be). A distribution made under this Article 12 to holders of such Senior Debt which otherwise would have
been made to Holders is not, as between Holdings or the relevant Guarantor and Holders, a payment by Holdings or such Guarantor on such Senior Debt. 

SECTION 12.07. Relative Rights. 

This Article 12 defines the relative rights of Holders and holders of Senior Debt of Holdings or a Guarantor. Nothing in this Indenture
shall: 
 (1) impair, as between Holdings or a Guarantor and Holders (as the case may be), the obligation of Holdings or such
Guarantor (as the case may be), which is absolute and unconditional, to pay its Guarantee to the extent set forth in Article 11; or 

(2) prevent the Trustee or any Holder from exercising its available remedies upon a default by Holdings or such Guarantor (as
the case may be) under its Guarantee, subject to the rights of holders of Senior Debt of Holdings or such Guarantor to receive distributions otherwise payable to Holders. 

  
 89 








 SECTION 12.08. Subordination May Not Be Impaired by Company. 

No right of any holder of Senior Debt of Holdings or any Guarantor to enforce the subordination of the Guarantee of Holdings or such Guarantor
(as the case may be) shall be impaired by any act or failure to act by Holdings or such Guarantor (as the case may be) or by its failure to comply with this Indenture. 

SECTION 12.09. Rights of Trustee and Paying Agent. 

Notwithstanding anything in this Article 12, the Trustee or Paying Agent shall continue to make payments on any Guarantee, and shall not
be charged with knowledge of the existence of facts that would prohibit the making of any payments to or by the Trustee, unless and until, not less than two Business Days prior to the date of such payment, a Responsible Officer of the Trustee
receives written notice satisfactory to it that such payments are prohibited by this Article 12. The Company, Holdings or the relevant Guarantor, a Representative or a holder of Senior Debt of Holdings or such Guarantor (as the case may be)
shall be entitled to give the notice; provided, however, that, if an issue of Senior Debt of Holdings or any Guarantor (as the case may be) has a Representative, only the Representative shall be entitled to give the notice. Prior to
the receipt of any such written notice, the Trustee shall be entitled in all respects conclusively to presume that no such fact exists. Unless the Trustee shall have received the notice provided for in the preceding sentence, the Trustee shall have
full power and authority to receive such payment and to apply the same to the purpose for which it was received and shall not be affected by any notice to the contrary which may be received by it on or after such date. The foregoing shall not apply
to any Affiliate of the Company acting as Paying Agent. 
 The Trustee, in its individual or any other capacity, shall be entitled to hold
Senior Debt of Holdings or any Guarantor with the same rights it would have if it were not the Trustee. The Registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this
Article 12 with respect to any Senior Debt of Holdings or any Guarantor which may at any time be held by it, to the same extent as any other holder of such Senior Debt; and nothing in Article 7 shall deprive the Trustee of any of its
rights as such holder. Notwithstanding anything in this Article 12 to the contrary, all amounts owed to the Trustee (including amounts owed pursuant to Section 7.07 hereof) in each of its capacities hereunder shall not be subordinated to
any Senior Debt of Holdings or a Guarantor or otherwise. 
 SECTION 12.10. Distribution or Notice to Representative. 

Whenever any Person is to make a distribution or give a notice to holders of Senior Debt of Holdings or any Guarantor, such Person shall be
entitled to make such distribution or give such notice to their Representative (if any). 
 SECTION 12.11. Article 12 Not to Prevent
Events of Default or Limit Right to Demand Payment. 
 The failure to make a payment pursuant to a Guarantee by reason of any provision
in this Article 12 shall not be construed as preventing the occurrence of a Default. Nothing in this Article 12 shall have any effect on the right of the Holders or the Trustee to make a demand for payment on Holdings or any Guarantor
pursuant to its Guarantee. 

  
 90 








 SECTION 12.12. Trustee Entitled to Rely. 

Upon any payment or distribution pursuant to this Article 12, the Trustee and the Holders shall be entitled to rely (1) upon any
order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 12.02 are pending, (2) upon a certificate of the liquidating trustee or agent or other Person making such payment or
distribution to the Trustee or to the Holders or (3) upon the Representatives for the holders of Senior Debt of Holdings or any Guarantor for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the
holders of such Senior Debt and other indebtedness of Holdings or such Guarantor (as the case may be), the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article 12. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Debt of Holdings or any Guarantor to participate in any payment or distribution
pursuant to this Article 12, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt of Holdings or such Guarantor (as the case may be) held by such
Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 12, and, if such evidence is not furnished, the Trustee shall be
entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions of actions by the Trustee
pursuant to this Article 12. 
 SECTION 12.13. Trustee to Effectuate Subordination. 

Each Holder, by accepting a Note, authorizes and directs the Trustee on its behalf to execute such documentation and to take such action as
may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders and the holders of Senior Debt of Holdings or any Guarantor as provided in this Article 12 and appoints the Trustee as attorney-in-fact for any
and all such purposes. 
 SECTION 12.14. Trustee Not Fiduciary for Holders of Senior Debt of Guarantor. 

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of Holdings or any Guarantor and shall not be liable
to any such holders if it shall mistakenly pay over or distribute to Holders or the Company or any other Person, money or assets to which any holders of such Senior Debt shall be entitled by virtue of this Article 12 or otherwise. With respect
to the holders of Senior Debt of Holdings or any Guarantor, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article and no implied covenants or obligations with respect
to holders of Senior Debt of Holdings or any Guarantor shall be read into this Indenture against the Trustee. 
 SECTION 12.15. Reliance
by Holders of Senior Debt of Holdings or Guarantors on Subordination Provisions. 
 Each Holder, by accepting a Note, acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each 

  
 91 








 
holder of any Senior Debt of Holdings or any Guarantor, whether such Senior Debt was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue
to hold, such Senior Debt, and such holder of Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Debt.

“Rule 144A Global Note”) and Initial Notes initially resold pursuant to Regulation S shall be issued initially in the form of one or more temporary global notes in fully registered form (collectively, the

the Initial Notes represented thereby with the Notes Custodian, and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as provided in this Indenture. Except as set
forth in this Section 2.1(a), beneficial ownership interests in the Temporary Regulation S Global Note (x) will not be exchangeable for interests in the Rule 144A Global Note, a permanent global note (the “Permanent
Regulation S Global Note” and, together with the Temporary Regulation S Global Notes, the “Regulation S Global Notes”), or any other Note prior to the expiration of the Distribution Compliance Period and
(y) after the expiration of the Distribution Compliance Period, may be exchanged for interests in a Rule 144A Global Note or the Permanent Regulation S Global Note only upon certification that beneficial ownership interests in such
Temporary Regulation S Global Note are owned either by non-U.S. persons or U.S. persons who purchased such interests in a transaction that did not require registration under the Securities Act. 

Beneficial interests in a Temporary Regulation S Global Note may be exchanged for interests in a Rule 144A Global Note if (1) such
exchange occurs in connection with a transfer of Securities in compliance with Rule 144A, and (2) the transferor of the beneficial interest in such Temporary Regulation S Global Note first delivers to the Trustee a written certificate (in
a form satisfactory to the Trustee) to the effect that the beneficial interest in such Temporary Regulation S Global Note is being transferred (a) to a Person who the transferor reasonably believes to be a QIB, (b) to a Person who is
purchasing for its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A and (c) in accordance with all applicable securities laws of the States of the United States and other jurisdictions. 

Beneficial interest in a Rule 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in a
Regulation S Global Note, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided n the Indenture) to the effect that such
transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable). 
 The Rule 144A
Global Note, the Temporary Regulation S Global Note and the Permanent Regulation S Global Note are collectively referred to herein as “Global Notes”. The 

  
 101 








 
aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depository and the Notes Custodian as
hereinafter provided. 
 (b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Note deposited with or
on behalf of the Depository. 
 The Company shall execute and the Trustee shall, in accordance with this Section 2.1(b), authenticate
and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depository for such Global Note or Global Notes or the nominee of such Depository and (b) shall be delivered by the Trustee to such Depository
or pursuant to such Depository’s instructions or held by the Notes Custodian. 
 Members of, or participants in, the Depository
(“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository or by the Notes Custodian or under such Global Note, and the Company, the Trustee and any agent of
the Company or the Trustee shall be entitled to treat the Depository 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 Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository
governing the exercise of the rights of a holder of a beneficial interest in any Global Note. 
 (c) Certificated Notes. Except as
provided in this Section 2.1 or Sections 2.3 or 2.4, owners of beneficial interests in Global Notes shall not be entitled to receive physical delivery of Definitive Notes. 

2.2 Authentication. The Trustee shall authenticate and deliver: (1) on the Issue Date, an aggregate principal amount of
$1,200,000,000 of 6.500% Senior Subordinated Notes due 2024; and (2) any Additional Notes for an original issue in an aggregate principal amount specified in the written order of the Company pursuant to Section 2.02 of the Indenture
and (3) Exchange Notes or Private Exchange Notes for issue only in a Registered Exchange Offer or a Private Exchange, respectively, pursuant to a Registration Rights Agreement, for a like principal amount of Initial Notes, in each case upon a
written order of the Company signed by two Officers. Such order shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of any issuance of Additional Notes
pursuant to Section 2.14 of the Indenture, shall certify that such issuance is in compliance with Section 4.09 of the Indenture. 

2.3 Transfer and Exchange. (a) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to a
Registrar with a request: 
 (x) to register the transfer of such Definitive Notes; or 

(y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, 


  
 102 








 the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements
for such transaction are met; provided, however, that the Definitive Notes surrendered for transfer or exchange: 

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the
Company and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 

(ii) if such Definitive Notes are required to bear a restricted securities legend, they are being transferred or exchanged
pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as
applicable: 
 (A) if such Definitive Notes are being delivered to the Registrar by a Holder for registration in the
name of such Holder, without transfer, a certification from such Holder to that effect; or 
 (B) if such Definitive
Notes are being transferred to the Company, a certification to that effect; or 
 (C) if such Definitive Notes are being
transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act:
(x) a certification to that effect (in the form set forth on the reverse of the Note) and (y) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set
forth in the legend set forth in Section 2.3(e)(i). 
 (b) Restrictions on Transfer of a Definitive Note for a Beneficial Interest
in a Global Security. A Definitive Note may not be exchanged for a beneficial interest in a Rule 144A Global Security or a Permanent Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the
Trustee of a Definitive Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 

(i) certification, in the form set forth on the reverse of the Note, that such Definitive Note is either (A) being
transferred to a QIB in accordance with Rule 144A or (B) is being transferred after expiration of the Distribution Compliance Period by a Person who initially purchased such Note in reliance on Regulation S to a buyer who elects to
hold its interest in such Note in the form of a beneficial interest in the Permanent Regulation S Global Note; and 

(ii) written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its
books and records with respect to such Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)) or Permanent Regulation S Note (in the case of a transfer pursuant to clause (b)(i)(B)) to


  
 103 








 
reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, such instructions to
contain information regarding the Depository account to be credited with such increase, 
 then the Trustee shall cancel such Definitive Note and cause, or
direct the Notes Custodian to cause, in accordance with the standing instructions and procedures existing between the Depository and the Notes Custodian, the aggregate principal amount of Notes represented by the Rule 144A Global Note or
Permanent Regulation S Global Note, as applicable, to be increased by the aggregate principal amount of the Definitive Note to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a
beneficial interest in the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, equal to the principal amount of the Definitive Note so canceled. If no Rule 144A Global Notes or Permanent Regulation S Global
Notes, as applicable, are then outstanding, the Company shall issue, and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Rule 144A Global Note or Permanent Regulation S
Global Note, as applicable, in the appropriate principal amount. 
 (c) Transfer and Exchange of Global Notes. (i) The transfer
and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository
therefor. A transferor of a beneficial interest in a Global Note shall deliver to the Registrar a written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to
be credited with a beneficial interest in the Global Note. The Registrar shall, in accordance with such instructions, instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global
Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred. 

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in
another Global Note, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to
be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred. 

(iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a
Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor
Depository or a nominee of such successor Depository. 
 (iv) In the event that a Global Note is exchanged for
Definitive Notes pursuant to Section 2.4 of this Appendix prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Notes, such


  
 104 








 
Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on
the reverse of the Initial Notes intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Company. 

(d) Restrictions on Transfer of Temporary Regulation S Global Notes. During the Distribution Compliance Period, beneficial
ownership interests in Temporary Regulation S Global Notes may be sold, pledged or transferred only (i) to the Company, (ii) in an offshore transaction in accordance with Regulation S (other than a transaction resulting in an exchange

(e) Legend. 

(i) Except as permitted by the following paragraphs (ii), (iii) and (iv), each Note certificate evidencing the
Global Notes (and all Notes issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form: 

THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS NOTE MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS NOTE IS HEREBY
NOTIFIED THAT THE SELLER OF THIS NOTE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 

THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR
OTHERWISE TRANSFERRED, ONLY (I) TO THE COMPANY, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING
THE REQUIREMENTS OF RULE 144A, (III) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (IV) PURSUANT TO EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY
RULE 144 THEREUNDER (IF AVAILABLE), (V) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OR (VI) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I)
THROUGH (VI) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY 

  
 105 








 
STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN
(A) ABOVE. 
 Each Definitive Note will also bear the following additional legend: 

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS. 

(ii) Upon any sale or transfer of a Transfer Restricted Note (including any Transfer Restricted Note represented by a Global
Note) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Note for a certificated Note that does not bear the legend set forth above and rescind any restriction
on the transfer of such Transfer Restricted Note, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the
Note). 
 (iii) After a transfer of any Initial Notes or Private Exchange Notes pursuant to and during the period of the
effectiveness of a Shelf Registration Statement with respect to such Initial Notes or Private Exchange Notes, as the case may be, all requirements pertaining to legends on such Initial Note or such Private Exchange Note will cease to apply, the
requirements requiring any such Initial Note or such Private Exchange Note issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Note or Private Exchange Note or an Initial Note or Private Exchange Note
in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Notes or Private Exchange Notes upon exchange of such transferring Holder’s certificated Initial Note or
Private Exchange Note or appropriate directions to transfer such Holder’s interest in the Global Note, as applicable. 

(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Notes, all requirements pertaining to
such Initial Notes that Initial Notes issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Notes that do not exchange their Initial Notes, and Exchange Notes in certificated or global form, in
each case without the restrictive securities legend set forth in Exhibit A hereto, will be available to Holders that exchange such Initial Notes in such Registered Exchange Offer. 

(v) Upon the consummation of a Private Exchange with respect to the Initial Notes, all requirements pertaining to such Initial
Notes that Initial Notes issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Notes that do not exchange their Initial Notes, and Private Exchange Notes in global form with the global securities
legend and the Restricted Notes Legend set forth in Exhibit A 

  
 106 








 
hereto, will be available to Holders that exchange such Initial Notes in such Private Exchange. 

(f) Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for
Definitive Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Depository for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for certificated Notes, redeemed, purchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced, and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities
Custodian) with respect to such Global Note, by the Trustee or the Securities Custodian, to reflect such reduction. 
 (g) No Obligation
of the Trustee. 
 (i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a
member of, or a participant in the Depository or other Person with respect to the accuracy of the records of the Depository 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 to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and
communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Note).
The rights of beneficial owners in any Global Note shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information
furnished by the Depository with respect to its members, participants and any beneficial owners. 
 (ii) 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 Depository participants, members or beneficial owners 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. 

2.4 Certificated Notes.

 [FORM OF REVERSE SIDE OF INITIAL NOTE] 

6.500% SENIOR SUBORDINATED NOTES DUE 2024 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

1. Interest. TransDigm Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture, being
herein called the “Company”), promises to pay interest on the principal amount of this Note at 6.500% per annum from June 4, 2014 until maturity; provided that, if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest (the “Additional Interest”) of $0.05 per week per $1,000 principal amount of Notes will accrue on the Notes for the first 90-day period immediately following the occurrence
of a Registration Default (increasing by an additional $0.05 per week per $1,000 principal amount of Notes with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of
1.00% per annum). The Company shall pay interest and Additional Interest semi-annually on January 15 and July 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest
Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of
interest, and if this Note is authenticated after July 15, 2014 and between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date;
provided, further, that the first Interest Payment Date shall be January 15, 2015. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is equal to the interest rate on the Note then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and
Additional Interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) and Additional Interest, if any, to the
Persons who are registered Holders at the close of business on the January 1 or July 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest and Additional Interest, if any, at the office or agency of the Company maintained for such purpose
within or without the City and State of New York, or, at the option of the Company, payment of interest and Additional Interest, if any, 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 will be required with respect to principal of and interest, premium and Additional Interest, if any, on, all Global Notes and all other Notes the Holders of which shall
have provided wire transfer instructions to the Company or 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. 

  
 5 








 3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A.,
the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 

4. Indenture. The Company issued the Notes under an Indenture dated as of June 4, 2014 (“Indenture”) among the
Company, Holdings, the Guarantors and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note
conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company. 

5. Subordination. The Notes are subordinated to Senior Debt of the Company, as defined in the Indenture. To the extent provided in the
Indenture, Senior Debt of the Company must be paid before the Notes may be paid. The Company agrees, and each Holder, by accepting a Note, agrees, to the subordination provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose. 
 6. Optional Redemption. 

On and after the date hereof, the Company shall be entitled to redeem the Notes (which includes Additional Notes, if any) at its option, in
whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as percentages of the principal amount thereof) (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date) if redeemed during the twelve-month period commencing on July 15 of the year set forth below: 
  

					
	 Year
	  	Percentage	 
	 2019
	  	 	103.250	% 
	 2020
	  	 	101.625	% 
	 2021 and thereafter
	  	 	100.000	% 

 In addition, prior to July 15, 2017, the Company shall be entitled at its option on one or more occasions
to redeem Notes (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Notes (which includes Additional Securities, if any) originally issued at a redemption price
(expressed as a percentage of principal amount) of 106.500%, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest
payment date), with an amount not to exceed the net cash proceeds from one or more Equity Offerings (provided that if the Equity Offering is an offering by Holdings, a portion of the Net Cash Proceeds thereof equal to the amount required to redeem
any such Notes is contributed to the equity capital of the Company); provided, however, that: (1) at least 65% of such aggregate principal amount of Notes (which includes Additional Notes, if 

  
 6 








 
any) remains outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly by the Company or its Affiliates); and (2) each such
redemption occurs within 90 days after the date of the related Equity Offering. 
 Notice of any redemption upon any Equity Offering may be
given prior to the completion thereof, and any such redemption or notice may, at the Company’s discretion, be subject to the completion of the related Equity Offering. 

Prior to July 15, 2019, the Company shall be entitled at its option to redeem all or a portion of the Notes at a redemption price equal
to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant
interest payment date). Notice of such redemption shall be sent to The Depository Trust Company (“DTC”), in the case of Global Notes, or mailed by first-class mail to each Holder’s registered address in the case of certificated notes
(and, to the extent permitted by applicable procedures and regulations, electronically), not less than 30 nor more than 60 days prior to the redemption date. 

7. Mandatory Redemption. The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to
the Notes. 
 8. Repurchase at Option of Holder. 

If a Change of Control occurs, each Holder will have the right to require that the Company purchase all or a portion of such Holder’s
Notes pursuant to the offer described in the Indenture (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued interest and Additional Interest, if any, to the date of
purchase. Within 30 days following the date upon which the Change of Control occurred, the Company must send in the case of Global Notes, through the facilities of DTC, and in the case of certificated notes, by first class mail, a notice to the
Trustee and each Holder, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is
mailed, other than as may be required by law (the “Change of Control Payment Date”). Holders electing to have a Note purchased pursuant to a Change of Control Offer shall be required to surrender the Note, with the form entitled
“Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

 If the Company or a Restricted Subsidiary consummates any Asset Sales, under certain circumstances, the Company is required to commence
an offer to all Holders (a “Net Proceeds Offer”) pursuant to Section 3.09 of the Indenture. The Net Proceeds Offer may also be made to holders of other Senior Subordinated Debt of the Company or a Restricted Subsidiary of the
Company requiring the making of such an offer. Pursuant to the Net Proceeds Offer, the Company shall offer to purchase, on a pro rata basis, the maximum amount of Notes and, if it so elects, such other Senior Subordinated Debt that may be
purchased with the Net Proceeds Offer Amount at a price equal to 100% of their principal amount (or, in the event such other Senior Subordinated Debt was issued with significant original issue discount, 100% of the accreted


  
 7 








 
value thereof) plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of purchase, in accordance with the procedures set forth in the Indenture (or, in respect of
such other Senior Subordinated Debt, such lesser price, if any, as may be provided for by the terms of such Senior Subordinated Debt). To the extent that the aggregate amount of Notes or such other Senior Subordinated Debt tendered pursuant to a Net
Proceeds Offer is less than the Net Proceeds Offer Amount, the Company may use such deficiency for general corporate purposes or for any other purpose not prohibited by the Indenture. If the aggregate principal amount of Notes or such other Senior
Subordinated Debt surrendered by holders thereof exceeds the amount of Net Proceeds Offer Amount, the Company shall select the Notes to be purchased in accordance with the depository’s procedures (based on amounts tendered). Holders of Notes
that are the subject of an offer to purchase will receive a Net Proceeds Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Notes. 
 9. Notice of Redemption. Notice of redemption will be sent to DTC in case of Global
Notes and in the case of certificated notes mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be
redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on Notes or portions thereof called for redemption. 

10. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered, and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents, and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except
for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes during a period beginning at the opening of business 15 days before the day of the mailing of notice of
redemption and ending at the close of business on such day or during the period between a record date and the next succeeding Interest Payment Date. 

11. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes. 

12. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Guarantees or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal amount of the then-outstanding Notes, if any, voting as a single class, and any existing default or compliance with any provision of the Indenture, the Guarantees or
the Notes may be waived with the consent of the Holders of a majority in principal amount of the then-outstanding Notes, if any, voting as a single class. Without the consent of any Holder, the Indenture, the Guarantees or the Notes may be amended
or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 of the Indenture or the Appendix to the Indenture
relating to the form of the Notes (including the related definitions) in a manner 

  
 8 








 
that does not materially adversely affect any Holder, to provide for the assumption of the Company’s, Holdings’ or any Guarantor’s obligations to Holders by a successor to the
Company, Holdings or a Guarantor pursuant to Section 5.01 of the Indenture, to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under the Indenture of any
such Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act, to provide for the issuance of Notes issued after the Issue Date in accordance with the
limitations set forth in the Indenture, to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Guarantee with respect to the Notes to provide for the issuance of exchange notes or private exchange notes, to conform the
text of the Indenture, the Guarantees or the Notes to any provision in the Description of Notes or to the extent that such provision in the Description of Notes was intended to be a verbatim recitation of a provision in the Indenture, the Guarantees
or the Notes. 
 13. Defaults and Remedies. Events of Default include: (i) the failure to pay interest or Additional Interest,
if any, on any Notes when the same becomes due and payable if the default continues for a period of 30 days (whether or not such payment shall be prohibited by Article 10 or Article 12 of the Indenture); (ii) the failure to pay the
principal on any Notes when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer on the
date specified for such payment in the applicable offer to purchase) (whether or not such payment shall be prohibited by Article 10 or Article 12 of the Indenture); (iii) a default in the observance or performance of any other
covenant or agreement contained in the Indenture if the default continues for a period of 60 days (or 180 days in the case of the covenant described in Section 4.03 of the Indenture) after the Company receives written notice specifying the
default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the case of a default with respect to Section 5.01 of the Indenture, which will
constitute an Event of Default with such notice requirement but without such passage of time requirement); (iv) the failure to pay at final stated maturity (giving effect to any applicable grace periods and any extensions thereof) the principal
amount of any Indebtedness of the Company or any Significant Subsidiary of the Company (other than a Securitization Entity), or the acceleration of the final stated maturity of any such Indebtedness, if the aggregate principal amount of such
Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated, aggregates to $50.0 million or more at any time; (v) one or more
judgments in an aggregate amount in excess of $50.0 million shall have been rendered against the Company or any of its Significant Subsidiaries, and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such
judgment or judgments become final and non-appealable; and (vi) certain events of bankruptcy affecting the Company or any of its Significant Subsidiaries. If an Event of Default (other than an Event of Default specified in clause
(vi) above with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then-outstanding Notes may declare all the Notes to be due and payable. Notwithstanding the foregoing, in
the case of an Event of Default arising from certain events of bankruptcy with respect to the Company or any of its Significant Subsidiaries, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce
the Indenture or the Notes except as provided in the Indenture and the Trust Indenture Act. Subject to certain limitations, Holders of a majority in 

  
 9 








 
principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of principal or interest or Additional Interest) if it determines that withholding notice is in their interest. 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 the Indenture except a continuing Default or Event of Default in the
payment of interest (including Additional Interest, if any) on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
 14.
Guarantee. The payment by the Company of the principal of, and premium and interest (including Additional Interest, if any) on, the Notes is fully and unconditionally guaranteed on a joint and several senior subordinated basis by Holdings and
each of the Guarantors. 
 15. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 

16. No Recourse Against Others. A past, present or future director, officer, employee, incorporator or stockholder of Holdings, the
Company or any Guarantor (other than the Company, Holdings or any Guarantor), as such, shall not have any liability for any obligations of Holdings, the Company or such Guarantor under the Notes, the Guarantees or the Indenture or for any claim
based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 

17. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

 18. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in
common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

19. Additional Rights of Holders of Restricted Global Notes and Restricted Definitive Notes. In addition to the rights provided to
Holders under the Indenture, Holders shall have all the rights set forth in the Registration Rights Agreement dated as of June 4, 2014 (the “Registration Rights Agreement”), among the Company, Holdings, the Guarantors and
Morgan Stanley & Co. LLC and Credit Suisse Securities (USA) LLC, as representatives of the initial purchasers of the Notes. Each Holder, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement,
including the obligations of the Holders with respect to a registration and the indemnification of the Company and other named persons to the extent provided therein.

 20. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP or ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to
the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 

The Company will furnish to any Holder, upon written request and without charge, a copy of the Indenture and/or the Registration Rights
Agreement. Requests may be made to:

 [FORM OF REVERSE SIDE OF EXCHANGE NOTE OR PRIVATE EXCHANGE NOTE] 

6.500% SENIOR SUBORDINATED NOTES DUE 2024 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

1. Interest. TransDigm Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture, being
herein called the “Company”), promises to pay interest on the principal amount of this Note at 6.500% per annum from June 4, 2014 until maturity; provided that, if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest (the “Additional Interest”) of $0.05 per week per $1,000 principal amount of Notes will accrue on the Notes for the first 90-day period immediately following the occurrence
of a Registration Default (increasing by an additional $0.05 per week per $1,000 principal amount of Notes with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of
1.00% per annum). The Company shall pay interest and Additional Interest semi-annually on January 15 and July 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest
Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of
interest, and if this Note is authenticated after July 15, 2014 and between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date;
provided, further, that the first Interest Payment Date shall be January 15, 2015. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is equal to the interest rate on the Note then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and
Additional Interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) and Additional Interest, if any, to the
Persons who are registered Holders at the close of business on the January 1 or July 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest and Additional Interest, if any, at the office or agency of the Company maintained for such purpose
within or without the City and State of New York, or, at the option of the Company, payment of interest and Additional Interest, if any, 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 will be required with respect to principal of and interest, premium and Additional Interest, if any, on, all Global Notes and all other Notes the Holders of which shall
have provided wire transfer instructions to the Company or 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. 

  
 3 








 3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A.,
the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 

4. Indenture. The Company issued the Notes under an Indenture dated as of June 4, 2014 (“Indenture”) among the
Company, Holdings, the Guarantors and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note
conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company. 

5. Subordination. The Notes are subordinated to Senior Debt of the Company, as defined in the Indenture. To the extent provided in the
Indenture, Senior Debt of the Company must be paid before the Notes may be paid. The Company agrees, and each Holder, by accepting a Note, agrees, to the subordination provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose. 
 6. Optional Redemption. 

On and after the date hereof, the Company shall be entitled to redeem the Notes (which includes Additional Notes, if any) at its option, in
whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as percentages of the principal amount thereof) (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date) if redeemed during the twelve-month period commencing on July 15 of the year set forth below: 
  

					
	 Year
	  	Percentage	 
	 2019
	  	 	103.250	% 
	 2020
	  	 	101.625	% 
	 2021 and thereafter
	  	 	100.000	% 

 In addition, prior to July 15, 2017, the Company shall be entitled at its option on one or more occasions
to redeem Notes (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Notes (which includes Additional Securities, if any) originally issued at a redemption price
(expressed as a percentage of principal amount) of 106.500%, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest
payment date), with an amount not to exceed the net cash proceeds from one or more Equity Offerings (provided that if the Equity Offering is an offering by Holdings, a portion of the Net Cash Proceeds thereof equal to the amount required to redeem
any such Notes is contributed to the equity capital of the Company); provided, however, that: (1) at least 65% of such aggregate principal amount of Notes (which includes Additional Notes, if 

  
 4 








 
any) remains outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly by the Company or its Affiliates); and (2) each such
redemption occurs within 90 days after the date of the related Equity Offering. 
 Notice of any redemption upon any Equity Offering may be
given prior to the completion thereof, and any such redemption or notice may, at the Company’s discretion, be subject to the completion of the related Equity Offering. 

Prior to July 15, 2019, the Company shall be entitled at its option to redeem all or a portion of the Notes at a redemption price equal
to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant
interest payment date). Notice of such redemption shall be sent to The Depository Trust Company (“DTC”), in the case of Global Notes, or mailed by first-class mail to each Holder’s registered address in the case of certificated notes
(and, to the extent permitted by applicable procedures and regulations, electronically), not less than 30 nor more than 60 days prior to the redemption date. 

7. Mandatory Redemption. The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to
the Notes. 
 8. Repurchase at Option of Holder. 

If a Change of Control occurs, each Holder will have the right to require that the Company purchase all or a portion of such Holder’s
Notes pursuant to the offer described in the Indenture (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued interest and Additional Interest, if any, to the date of
purchase. Within 30 days following the date upon which the Change of Control occurred, the Company must send in the case of Global Notes, through the facilities of DTC, and in the case of certificated notes, by first class mail, a notice to the
Trustee and each Holder, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is
mailed, other than as may be required by law (the “Change of Control Payment Date”). Holders electing to have a Note purchased pursuant to a Change of Control Offer shall be required to surrender the Note, with the form entitled
“Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

 If the Company or a Restricted Subsidiary consummates any Asset Sales, under certain circumstances, the Company is required to commence
an offer to all Holders (a “Net Proceeds Offer”) pursuant to Section 3.09 of the Indenture. The Net Proceeds Offer may also be made to holders of other Senior Subordinated Debt of the Company or a Restricted Subsidiary of the
Company requiring the making of such an offer. Pursuant to the Net Proceeds Offer, the Company shall offer to purchase, on a pro rata basis, the maximum amount of Notes and, if it so elects, such other Senior Subordinated Debt that may be
purchased with the Net Proceeds Offer Amount at a price equal to 100% of their principal amount (or, in the event such other Senior Subordinated Debt was issued with significant original issue discount, 100% of the accreted


  
 5 








 
value thereof) plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of purchase, in accordance with the procedures set forth in the Indenture (or, in respect of
such other Senior Subordinated Debt, such lesser price, if any, as may be provided for by the terms of such Senior Subordinated Debt). To the extent that the aggregate amount of Notes or such other Senior Subordinated Debt tendered pursuant to a Net
Proceeds Offer is less than the Net Proceeds Offer Amount, the Company may use such deficiency for general corporate purposes or for any other purpose not prohibited by the Indenture. If the aggregate principal amount of Notes or such other Senior
Subordinated Debt surrendered by holders thereof exceeds the amount of Net Proceeds Offer Amount, the Company shall select the Notes to be purchased in accordance with the depository’s procedures (based on amounts tendered). Holders of Notes
that are the subject of an offer to purchase will receive a Net Proceeds Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Notes. 
 9. Notice of Redemption. Notice of redemption will be sent to DTC in case of Global
Notes and in the case of certificated notes mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be
redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on Notes or portions thereof called for redemption. 

10. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered, and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents, and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except
for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes during a period beginning at the opening of business 15 days before the day of the mailing of notice of
redemption and ending at the close of business on such day or during the period between a record date and the next succeeding Interest Payment Date. 

11. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes. 

12. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Guarantees or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal amount of the then-outstanding Notes, if any, voting as a single class, and any existing default or compliance with any provision of the Indenture, the Guarantees or
the Notes may be waived with the consent of the Holders of a majority in principal amount of the then-outstanding Notes, if any, voting as a single class. Without the consent of any Holder, the Indenture, the Guarantees or the Notes may be amended
or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 of the Indenture or the Appendix to the Indenture
relating to the form of the Notes (including the related definitions) in a manner 

  
 6 








 
that does not materially adversely affect any Holder, to provide for the assumption of the Company’s, Holdings’ or any Guarantor’s obligations to Holders by a successor to the
Company, Holdings or a Guarantor pursuant to Section 5.01 of the Indenture, to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under the Indenture of any
such Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act, to provide for the issuance of Notes issued after the Issue Date in accordance with the
limitations set forth in the Indenture, to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Guarantee with respect to the Notes to provide for the issuance of exchange notes or private exchange notes, to conform the
text of the Indenture, the Guarantees or the Notes to any provision in the Description of Notes or to the extent that such provision in the Description of Notes was intended to be a verbatim recitation of a provision in the Indenture, the Guarantees
or the Notes. 
 13. Defaults and Remedies. Events of Default include: (i) the failure to pay interest or Additional Interest,
if any, on any Notes when the same becomes due and payable if the default continues for a period of 30 days (whether or not such payment shall be prohibited by Article 10 or Article 12 of the Indenture); (ii) the failure to pay the
principal on any Notes when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer on the
date specified for such payment in the applicable offer to purchase) (whether or not such payment shall be prohibited by Article 10 or Article 12 of the Indenture); (iii) a default in the observance or performance of any other
covenant or agreement contained in the Indenture if the default continues for a period of 60 days (or 180 days in the case of the covenant described in Section 4.03 of the Indenture) after the Company receives written notice specifying the
default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the case of a default with respect to Section 5.01 of the Indenture, which will
constitute an Event of Default with such notice requirement but without such passage of time requirement); (iv) the failure to pay at final stated maturity (giving effect to any applicable grace periods and any extensions thereof) the principal
amount of any Indebtedness of the Company or any Significant Subsidiary of the Company (other than a Securitization Entity), or the acceleration of the final stated maturity of any such Indebtedness, if the aggregate principal amount of such
Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated, aggregates to $50.0 million or more at any time; (v) one or more
judgments in an aggregate amount in excess of $50.0 million shall have been rendered against the Company or any of its Significant Subsidiaries, and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such
judgment or judgments become final and non-appealable; and (vi) certain events of bankruptcy affecting the Company or any of its Significant Subsidiaries. If an Event of Default (other than an Event of Default specified in clause
(vi) above with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then-outstanding Notes may declare all the Notes to be due and payable. Notwithstanding the foregoing, in
the case of an Event of Default arising from certain events of bankruptcy with respect to the Company or any of its Significant Subsidiaries, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce
the Indenture or the Notes except as provided in the Indenture and the Trust Indenture Act. Subject to certain limitations, Holders of a majority in 

  
 7 








 
principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of principal or interest or Additional Interest) if it determines that withholding notice is in their interest. 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 the Indenture except a continuing Default or Event of Default in the
payment of interest (including Additional Interest, if any) on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
 14.
Guarantee. The payment by the Company of the principal of, and premium and interest (including Additional Interest, if any) on, the Notes is fully and unconditionally guaranteed on a joint and several senior subordinated basis by Holdings and
each of the Guarantors. 
 15. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 

16. No Recourse Against Others. A past, present or future director, officer, employee, incorporator or stockholder of Holdings, the
Company or any Guarantor (other than the Company, Holdings or any Guarantor), as such, shall not have any liability for any obligations of Holdings, the Company or such Guarantor under the Notes, the Guarantees or the Indenture or for any claim
based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 

17. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

 18. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in
common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

19. Additional Rights of Holders of Restricted Global Notes and Restricted Definitive Notes. In addition to the rights provided to
Holders under the Indenture, Holders shall have all the rights set forth in the Registration Rights Agreement dated as of June 4, 2014, among the Company, Holdings, the Guarantors and Morgan Stanley & Co. LLC and Credit Suisse
Securities (USA) LLC, as representatives of the initial purchasers of the Notes. Each Holder, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect
to a registration and the indemnification of the Company and other named persons to the extent provided therein.

 20. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP or ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to
the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 

The Company will furnish to any Holder, upon written request and without charge, a copy of the Indenture and/or the Registration Rights
Agreement. Requests may be made to:
