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;

(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 this 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 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. 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 of the Company 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 of the Company 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. 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 reasonably require of the names and addresses of Holders.

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 9.04 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 (i) 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, (ii) 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 (iii) 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 (i) the Holder of such Global Note (or its agent or the person on whose behalf the Global Note is held) or (ii) 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 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.

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 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 and Section 4.12 hereof, 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 and any Additional Notes 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; and

(3) 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.

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, The Depository Trust Company (“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; or, if the Notes are not so listed, by lot or otherwise in accordance with the procedures of DTC. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 10 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 a principal amount of $2,000 or in integral multiples of $1,000 in excess thereof. 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 10 days but not more than 60 days before a redemption date, the Company shall send to 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;

(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 five 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.

Except as provided in Section 3.07(e), 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. Except as provided in Section 3.07(e), 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.

SECTION 3.06. Notes Redeemed in Part.

Upon surrender of a Note in the form of a certificated 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.

(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.

(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, but excluding, 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 address in the case of certificated notes (and, to the extent permitted by applicable procedures and regulations, electronically), not less than 10 nor more than 60 days prior to the redemption date.

(g) The Trustee shall have no responsibility with respect to the determination of any redemption price or Applicable Premium.

SECTION 3.08. No Mandatory Redemption; Open Market Purchases.

(a) The Company is not required to make any mandatory redemption or sinking fund payments with respect to the Notes.

(b) The Company shall be entitled at its option at any time and from time to time to purchase Notes in the open market or otherwise.

SECTION 3.09. Offer to Purchase by Application of Net Proceeds Offer Amount.

In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence a Net Proceeds Offer, it shall follow the procedures specified below.

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 for any Notes so purchased shall be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be 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 Secured Debt of the Company or a Restricted Subsidiary of the Company pursuant to Section 4.10 hereof, the notice shall identify such Senior Secured Debt and state that the Net Proceeds Offer is also made to holders of such Senior Secured Debt;

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

(d) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Net Proceeds Offer shall cease to accrue interest after the Purchase Date;

(e) that Holders electing to have a portion of a Note purchased 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 Secured Debt surrendered by the holders thereof exceeds the Offer Amount, the Company shall select the Notes and other Senior Secured 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 Secured Debt tendered and with such adjustments as may be deemed appropriate by the Company so that only Notes or other Senior Secured 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 Secured 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 Secured 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 Secured Debt or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, DTC or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue (or cause to be delivered by book-entry transfer) a new Note, and the Trustee, with respect to a Note in certificated form, 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.

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

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

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

SECTION 4.04. Compliance Certificate.

(a) The Company and each Guarantor (to the extent that such Guarantor would be required under the TIA) shall deliver to the Trustee, within 90 days after the end of each fiscal year commencing in 2024, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has 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 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.

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.

SECTION 4.07. Restricted Payments.

The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

such Permitted Investment was not consummated to the extent required pursuant to the terms of such Indebtedness); or

(4) make any Investment (other than Permitted Investments):

(each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a “Restricted Payment”); if at the 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 Payment) made subsequent to December 14, 2010 (other than Restricted Payments made pursuant to clauses (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12), (13) and (14) of the following paragraph) shall exceed the sum of, without duplication:

(y) the amount by which Indebtedness of the Company is reduced on the Company’s balance sheet upon the conversion or 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 other than cash that would constitute Marketable Securities or a Permitted Business) received by the Company or any Restricted Subsidiary subsequent to December 14, 2010 (A) from any sale or other disposition of any Investment (other than a Permitted Investment) in any Person (including an Unrestricted Subsidiary) made by the Company and its Restricted Subsidiaries and (B) representing the return of capital or principal (excluding dividends and distributions otherwise included in Consolidated Net Income) with respect to such Investment and (II) the portion (proportionate to the Company’s equity interest in an Unrestricted Subsidiary) of the fair market value of the net assets of an Unrestricted Subsidiary at any 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.

Notwithstanding the foregoing, the provisions set forth in the immediately preceding paragraph shall not prohibit:

(1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of such dividend or notice of such redemption if the dividend or payment of the redemption price, as the case may be, would have been permitted on the date of declaration or notice;

(4) Dividend Equivalent Payments and payments to a direct or indirect parent of the Company for the purpose of permitting any of such entities to redeem or repurchase common equity or options in respect thereof, in each case in connection with the repurchase provisions of employee stock option or stock purchase agreements or other agreements to compensate management employees or upon the death, disability, retirement, severance or termination of employment of management employees; provided that all such Dividend Equivalent Payments and redemptions or repurchases pursuant to this clause (4) shall not exceed in any fiscal year the sum of (A) $100.0 million in any fiscal year carried over to succeeding fiscal years (with unused amounts under the corresponding provisions related to the Existing Secured Notes, the 2027 5.50% Notes, the 2029 4.625% Notes and the 2029 4.875% Notes so carrying over as of the Issue Date) subject to a maximum (without giving effect to the following clause (B)) of $200.0 million in any fiscal year plus (B) any amounts not utilized in any preceding fiscal year following December 14, 2010 that were otherwise available under this clause (4) for such purchases (which aggregate amount shall be increased by the amount of any net cash proceeds received from the sale since December 14, 2010 of Capital Stock (other than Disqualified Capital Stock) to members of the Company’s management team that have not otherwise been applied to the payment of Restricted Payments pursuant to the terms of clause (ii) of the immediately preceding paragraph or clause (2) of this paragraph and 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;

(5) the declaration and payment of dividends by the Company to, or the making of loans to, its direct parent company in amounts required for the Company’s direct or indirect parent companies to pay (A) franchise taxes and other fees, taxes and expenses required to maintain their corporate existence, (B) Federal, state and local income taxes, to the extent such income taxes are attributable to the income of the Company and the Restricted Subsidiaries and, to the extent of the amount actually received from its Unrestricted Subsidiaries, in amounts required to pay such taxes to the extent attributable to the income of such Unrestricted Subsidiaries; provided, however, that the amount of such payments in any fiscal year does not exceed the amount that the Company and its consolidated Subsidiaries would be required to pay in respect of Federal, state and local taxes for such fiscal year were the Company to pay such taxes as a stand-alone taxpayer, (C) customary salary, bonus and other benefits payable to officers and employees of any direct or indirect parent company of the Company to the extent such salaries, bonuses and other benefits are attributable to the ownership or operation of the Company and the Restricted Subsidiaries, (D) general corporate overhead expenses of any direct or indirect parent company of the Company to the extent such expenses are attributable to the ownership or operation of the Company and the Restricted Subsidiaries and (E) reasonable fees and expenses incurred in connection with any unsuccessful debt or equity offering by such direct or indirect parent company of the Company;

(9) payments of dividends on Disqualified Capital Stock issued in compliance with Section 4.09 hereof;

(10) Restricted Payments made with Net Cash Proceeds from Asset Sales remaining after application thereof as required by Section 4.10 hereof (including after the making by the Company of any Net Proceeds Offer required to be made by the Company pursuant to such Section and the application of the entire Net Proceeds Offer Amount to purchase all Notes and other Senior Secured Debt of the Company or a Restricted Subsidiary of the Company tendered therein);

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

(12) cash payments in lieu of fractional shares in connection with the exercise of warrants, stock options or other securities convertible into or exchangeable into Capital Stock of the Company;

(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 or the Guarantees 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 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 Security Documents, the Intercreditor Agreement, the Notes, the Existing Secured Notes (including the Senior Secured Debt Documents related to the Existing Secured Notes), the 2027 5.50% Notes, the 2029 4.625% Notes, the 2029 4.875% Notes and the guarantees in respect thereof; (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 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 (such Indebtedness, “Ratio Indebtedness”); provided, however, that (x) 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 $400.0 million at any one time outstanding and (y) if such Ratio Indebtedness is to be used in whole or in part to finance a Limited Condition Acquisition, such calculation shall be determined solely as of the date on which the definitive documentation with respect to such Limited Condition Acquisition is entered into.

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) solely with respect to any Asset Sale or series of related Asset Sales for which the Company and its Restricted Subsidiaries receive aggregate consideration in excess of $50.0 million, 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 sheet or the footnotes thereto if such incurrence or accrual had taken place on the date of such balance 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 Secured 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); and provided further that this requirement shall be deemed satisfied if the Company or such Restricted Subsidiary has made an investment in Productive Assets within 180 days prior to an Asset Sale) or

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 (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 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 Secured 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 Secured 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 Secured 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 Secured Debt,

such lesser price, if any, as may be provided for by the terms of such Senior Secured 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 (x) that to the extent the assets that are the subject of such Asset Sale constitute Collateral, (i) any such Productive Assets shall promptly constitute Collateral and (ii) 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 and (y) that to the extent the assets that are the subject of such Asset Sale do not constitute Collateral, 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 (except that the term “Senior Debt” shall be deemed to replace in each instance in such preceding paragraph the phrase “Secured Debt” or “Senior Secured Debt”, as applicable).

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 Secured Debt tendered pursuant to a Net Proceeds Offer is less than the Net Proceeds Offer Amount, the Company may use any 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 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 unless (1) such Secured Debt is secured by a Lien (the “Initial Lien”) that expressly ranks junior to the first-priority security interests intended to be created in favor of the Notes Collateral Agents for the benefit of the Indenture Secured Parties pursuant to the Security Documents and the Intercreditor Agreement or (2) such Initial Lien is a Permitted 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 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 and unpaid 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 send 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 sending 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 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. [Intentionally Omitted].

SECTION 4.17. Additional Guarantees.

The Company shall cause each of its direct and indirect Restricted Subsidiaries that is a borrower or guarantor under the Credit Facilities or that issues or guarantees any Capital Markets Indebtedness of the Company or any Guarantor in an aggregate principal amount of at least $200.0 million, within 20 Business Days of incurring such Indebtedness, to execute and deliver a supplemental indenture to this Indenture, providing for a senior guarantee of payment of the Notes by such Restricted Subsidiary.

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 this 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 this 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 4.17;

(8) Section 4.18;

(9) Section 4.20; 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 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 (iii) 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 becoming 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.

SECTION 4.20. Impairment of Security Interest.

Subject to the rights of the holders of Permitted Liens and except as permitted by this Indenture, the Security Documents or the Intercreditor Agreement (including the release of any Collateral as permitted hereunder or thereunder), the Company shall not, and shall not permit any of its Restricted Subsidiaries to, take or knowingly or negligently omit to take, any action which action or omission would reasonably be expected to have the result of materially impairing the security interest with respect to a material portion of the Collateral for the benefit of the Indenture Secured Parties.

(1) (except in the case of such Guarantor that has been disposed of in its entirety to another Person (other than to the Company or an Affiliate of the Company), whether through a merger, consolidation or sale of Capital Stock or through the sale of all or substantially all of its assets (such sale constituting the disposition of such Guarantor in its entirety), if in connection therewith the Company provides an Officers’ Certificate to the Trustee to the 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 and the Security Documents to which it is a party, and the performance of each applicable covenant of or obligation under the

Security Documents and the Intercreditor Agreement to be performed or observed on the part of such Guarantor in its capacity as a Grantor;

(2) except in the case of a merger of such Guarantor with or into the Company or another Guarantor, 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 (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 this Indenture relating to such transaction have been satisfied.

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.

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 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.

“Events of Default” 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;

(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);

(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 then-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;

(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;

(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; or

(h) with respect to any Collateral having a fair market value in excess of $50 million, individually or in the aggregate, unless such Collateral has been released from the Liens in accordance with the provisions of the Security Documents and the Intercreditor Agreement, (i) the security interest with respect to such Collateral under any Security Document or the Intercreditor Agreement shall fail to be in full force and effect, for any reason, and such failure should continue for 60 days or (ii) the assertion by the Company or any Guarantor, in any pleading in any court of competent jurisdiction, that any security interest with respect to such Collateral under any Security Documents or the Intercreditor Agreement is invalid or unenforceable.

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 and 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 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, this Indenture, the Security Documents or the Intercreditor Agreement that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability.

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 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 and the Notes Collateral Agents (including any predecessor Trustee or Notes Collateral Agent), their 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 them (including any predecessor Trustee or Notes Collateral Agent) 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 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.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture, the Security Documents or the Intercreditor Agreement 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

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.

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

SECTION 7.05. Notice of Defaults.

(a) The Trustee shall not be deemed to have notice of any Default or Event of Default unless written notice of such a Default or Event of Default is received by a Responsible Officer of 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 (or otherwise transmit in accordance with the applicable procedures of DTC) 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 May 15, 2025, 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 to comply with 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 (if any) on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee whenever the Notes become 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 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.

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, with 30 days’ prior notice, so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

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

(b) the Trustee is adjudged bankrupt or insolvent, or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(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.

This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee shall comply with TIA § 310(b).

SECTION 7.11. Preferential Collection of Claims Against the Company.

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

ARTICLE VIII

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

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 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.17, 4.18 and 4.20 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 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 other Senior Debt, including those rights 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.

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 (x) have become due and payable, pursuant to an optional redemption notice or otherwise or (y) 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.

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 written 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, the Trustee and the Notes Collateral Agents, may amend or supplement this Indenture, the Guarantees, the Notes, any Security Document or the Intercreditor Agreement without the consent of any Holder:

(g) to allow any Guarantor to execute a supplemental indenture, a joinder to the Security Documents or the Intercreditor Agreement and/or a Guarantee with respect to the Notes; provided, however, that any such supplemental indenture, joinder and/or Guarantee need only be executed by the Company, such Guarantor and, as applicable, the Trustee and the Notes Collateral Agents;

(h) to provide for the issuance of exchange notes or private exchange notes in exchange for 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 Sections 7.02 and 11.02 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, the Notes, the Security Documents and the Intercreditor Agreement 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 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 Sections 7.02 and 11.02 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 send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send 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;

(f) make any change in the provisions of this Indenture protecting the legal 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.

Any modification, amendment or waiver of this Indenture or any Security Document that has the effect of releasing all or substantially all of the Collateral, taken as a whole, from the Liens securing the Notes other than in accordance with this Indenture and the Security Documents, or modifying the Intercreditor Agreement in any manner adverse in any material respect to the Holders, will require the consent of the Holders of at least 66²⁄₃% in aggregate principal amount of the Notes.

SECTION 9.03. [Intentionally Omitted].

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.

SECTION 9.06. Trustee to Sign Amendments, etc.

The Trustee shall sign any amendment 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 amendment 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 11.02 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture, the Security Documents and the Intercreditor Agreement.

ARTICLE X

GUARANTEES

SECTION 10.01. 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 10 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 10.07, 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.

Except as expressly set forth in Sections 10.02 and 10.07 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 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. 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 10.02. 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 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 10.03. Successors and Assigns.

This Article 10 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 10.04. 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 10 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 10 at law, in equity, by statute or otherwise.

SECTION 10.05. Modification.

No modification, amendment or waiver of any provision of this Article 10, 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 10.06. [Intentionally Omitted].

SECTION 10.07. Release of Guarantor.

A Guarantor shall be deemed released from all obligations under this Article 10 without any further action required on the part of the Trustee or any Holder:

(a) 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 such Guarantor, other than to the Company or an Affiliate of the Company and as permitted by this Indenture;

(b) upon the sale or disposition of all or substantially all the assets of such Guarantor, other than to the Company or an Affiliate of the Company and as permitted by this Indenture;

(d) if the Guarantor becomes an Immaterial Domestic Restricted Subsidiary and is not otherwise required to provide a Guarantee of the Notes pursuant Section 4.17 hereof or ceases to be a Subsidiary;

(e) upon the Guarantor being released or discharged from all of its obligations as a borrower or guarantor under the Credit Facilities and all other Capital Markets Indebtedness that gave rise to the requirement that such Guarantor provide such Guarantee pursuant to Section 4.17 hereof, except, in each case, a release or discharge as a result of the payment of such Guarantor’s guarantee or direct obligations under the Credit Facilities or such Guarantor’s guarantee under such Capital Markets Indebtedness, as applicable (it being understood that the release or discharge subject to a contingent reinstatement is still considered a release or discharge, and if any Indebtedness of such Guarantor under the Credit Facilities or such Capital Markets Indebtedness is reinstated, such Guarantee shall also be reinstated); or

(f) 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 (in which case the Guarantee of Holdings shall also be released);

At the request of the Company and upon receipt by the Trustee of the documents required by Section 11.02 hereof, the Trustee shall execute and deliver an appropriate instrument evidencing the release of a Guarantor pursuant to this Section 10.07.

SECTION 10.08. 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).

Each Notes Collateral Agent will be entitled to rely upon, and will not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it in good faith to be genuine and to have been signed or sent by the proper person. Each Notes Collateral Agent may consult with legal counsel (who may be counsel for the Company), independent accountants and other experts selected by it, and will not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. Without limiting the generality of the foregoing, each Notes Collateral Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers and shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose such Notes Collateral Agent to liability or that is contrary to any Security Document, the Intercreditor Agreements or applicable law;

(iii) shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Company or any of its Affiliates that is communicated to or obtained by the Person serving as a Notes Collateral Agent or any of its Affiliates in any capacity;

(iv) shall not be liable for any action taken or not taken by it (a) with the consent or at the request of any Applicable Collateral Agent (as defined in the Intercreditor Agreement) or (b) in the absence of its own gross negligence or willful misconduct or (c) in reliance on an Officers’ Certificate of the Company stating that such action is permitted by the terms of the Intercreditor Agreements. Each Notes Collateral Agent shall be deemed not to have knowledge of any event of default hereunder or under any series of First Lien Obligations unless and until written notice describing such event of default is received by such Notes Collateral Agent from the representative of such First Lien Obligations or Holdings or the Company; and

(v) shall not be responsible for or have any duty to ascertain or inquire into (a) any statement, warranty or representation made in or in connection with the Intercreditor Agreements or any Security Document, (b) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (c) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any event of default, (d) the validity, enforceability, effectiveness or genuineness of the Intercreditor Agreements, any other Security Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by any Security Document, (e) the existence, value or the sufficiency of any Collateral for any series of First Lien Obligations, or (f) the satisfaction of any condition set forth in

103

any operative agreements governing First Lien Obligations or any Security Document, other than to confirm receipt of items expressly required to be delivered to such Notes Collateral Agent.

The use of the term “agent” herein with reference to a Notes Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law other than as a “representative” as such term is used in Section 9-102(a)(72)(E) of the Uniform Commercial Code.

BY ACCEPTING A NOTE EACH HOLDER WILL BE DEEMED TO HAVE IRREVOCABLY AGREED TO THE FOREGOING PROVISIONS OF THIS SECTION 12.01(a) AND SHALL BE BOUND BY THOSE AGREEMENTS TO THE FULLEST EXTENT PERMITTED BY LAW.

(b) Without limiting the Intercreditor Agreements, each Notes Collateral Agent shall be subject to such directions as may be properly given in accordance with this Indenture, the Intercreditor Agreements and the Security Documents. Except as expressly required by this Indenture, the Intercreditor Agreements and the Security Documents, and in each case subject to the Intercreditor Agreements, no Notes Collateral Agent shall be obligated:

(i) to act upon directions purported to be delivered to it by any other Person;

(ii) to foreclose upon or otherwise enforce any Lien securing the Notes or any of the Guarantees; or

(iii) to take any other action whatsoever with regard to any or all of (x) the Liens securing the Notes, (y) the Guarantees or (z) the Security Documents, or with regard to the Collateral.

(c) Each Notes Collateral Agent may perform any and all of its duties and exercise its rights and powers by or through, and is authorized and empowered to appoint, one or more co-agents or sub-agents or attorneys-in-fact as it deems necessary or appropriate in connection herewith and shall not be liable for the negligence or misconduct of any such agents or attorneys-in-fact selected by it in good faith.

(d) Subject to the appointment and acceptance of a successor Notes Collateral Agent as provided below, either Notes Collateral Agent may resign at any time by notifying the Company and the Trustee. Upon any such resignation, the Company shall have the right to appoint a successor; provided that, during the existence and continuation of an Event of Default pursuant to clause (a), (b), (f) or (g) of Section 6.01, the Majority Holders shall have the right to appoint a successor. If no successor shall have been so appointed by the Company (or, if applicable, the Majority Holders) and shall have accepted such appointment within 30 days after the retiring Notes Collateral Agent gives notice of its resignation, then such retiring Notes Collateral Agent may, on behalf of the Holders and the Trustee, petition at the expense of the Company a court of competent jurisdiction to appoint a successor Notes Collateral Agent. Upon the acceptance of its appointment as a Notes Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of

104

the retiring Notes Collateral Agent, and the retiring Notes Collateral Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Company to a successor Notes Collateral Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Company and such successor. After a Notes Collateral Agent’s resignation hereunder, the provisions of this Article 12 and Article 7 shall continue in effect for the benefit of such retiring Notes Collateral Agent, its sub-agents and their respective Affiliates in respect of any actions taken or omitted to be taken by any of them while acting as Notes Collateral Agent.

(e) The benefits, protections and indemnities of the Trustee in Sections 7.02, 7.03 and 7.07 of this Indenture shall apply mutatis mutandi to each Notes Collateral Agent in its capacity as such, including, without limitation, the rights to receive and rely on Officers’ Certificates and Opinions of Counsel, reimbursement and indemnification; provided, that the applicable standard of care of the Notes Collateral Agents with respect to Section 7.02, 7.03 and 7.07 of this Indenture shall be gross negligence and willful misconduct.

(f) Each Holder, by its acceptance of any Notes, is deemed to have consented and agreed to the terms of each Security Document, as originally in effect and as amended, supplemented or replaced from time to time in accordance with its terms or the terms of this Indenture; and authorizes and empowers the Trustee and (through the Intercreditor Agreement) each Applicable Authorized Representative and Applicable Collateral Agent (each as defined in the Intercreditor Agreement) to bind the Holders and other holders of First Lien Obligations as set forth in the applicable Security Documents and Intercreditor Agreements to which they are a party and to perform its obligations and exercise its rights and powers thereunder. Notwithstanding the foregoing, no such consent or deemed consent shall be deemed or construed to represent an amendment or waiver, in whole or in part, of any provision of this Indenture or the Notes.

(g) Neither the Trustee nor the Notes Collateral Agents shall be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company or any Grantor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral.

(h) Beyond the exercise of reasonable care in the custody thereof, neither the Trustee nor the Notes Collateral Agents shall have any duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and neither the Trustee nor the Notes Collateral Agents shall be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. Each of the Trustee and the Notes Collateral Agents shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of

105

the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee or a Notes Collateral Agent in good faith.

(i) Neither the Trustee nor the Notes Collateral Agents shall be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Trustee or such Notes Collateral Agent, as applicable, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee and the Notes Collateral Agents shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Intercreditor Agreement or the Security Documents by the Company, the Guarantors or the Credit Agreement Collateral Agent.

(j) Notwithstanding any other provision hereof, neither the Notes Collateral Agents nor the Trustee shall have any duties or obligations hereunder or under the Intercreditor Agreement or any Security Document except those expressly set forth herein or therein. Without limiting the generality of the foregoing, in the event that a Notes Collateral Agent or the Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in such Notes Collateral Agent’s or the Trustee’s sole discretion may cause it to be considered an “owner or operator” under the provisions of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), 42 U.S.C. §9601, et seq., or otherwise cause it to incur liability under CERCLA or any other federal, state or local law, the Notes Collateral Agents and the Trustee each reserve the right, instead of taking such action, to either resign or arrange for the transfer of the title or control of the asset to a court-appointed receiver. Neither the Notes Collateral Agents nor the Trustee shall be liable to any person for any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of a Notes Collateral Agent’s actions and conduct as authorized, empowered and directed hereunder or relating to the discharge, release or threatened release of hazardous materials into the environment. If at any time it is necessary or advisable for the Collateral to be possessed, owned, operated or managed by any person other than the Grantor, the Majority Holders shall direct the applicable Notes Collateral Agent or Trustee, as applicable, to appoint an appropriately qualified person who they shall designate to possess, own, operate or manage, as the case may be, the Collateral.

(k) For the avoidance of doubt, the Trustee and the US Collateral Agent shall act only within the United States, and shall not be subject to any foreign law, be required to act in any jurisdiction located outside the United States or be required to execute any foreign law governed document.

SECTION 12.02. Acceptance of Security Documents.

The Trustee and each Holder, by accepting any Notes and the Guarantees, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now or

106

hereafter constituted shall be for the benefit of all the Holders, the Notes Collateral Agents and the Trustee, and that the Lien granted in the Security Documents relating to the Notes in respect of the Trustee, the Notes Collateral Agents and the Holders is subject to and qualified and limited in all respects by the Security Documents and the Intercreditor Agreements and actions that may be taken thereunder. In the event of conflict between any Intercreditor Agreement, any of the Security Documents and this Indenture, the applicable Intercreditor Agreement shall control.

SECTION 12.03. Further Assurances.

The Company and each Guarantor will, and will cause each Subsidiary that is a Guarantor to, execute and deliver, or cause to be executed and delivered, to each Notes Collateral Agent, as applicable, such documents, agreements and instruments, and will take or cause to be taken such further actions (including the filing and recording of financing statements, fixture filings and other documents and such other actions or deliveries of the type described under this Article 12 or the Security Documents (including legal opinions, title insurance policies, certificates and corporate and organizational documents)), which may be required by law or which the Trustee or a Notes Collateral Agent may, from time to time, reasonably request to carry out the terms and conditions of this Indenture and the Security Documents and to ensure perfection and priority of the Liens created or intended to be created by the Security Documents, in each case, subject to the Security Documents and the Intercreditor Agreements, all at the expense of the Grantors.

Subject to the limitations set forth above, if any material assets (including any owned real property or improvements thereon but excluding leasehold interests) (but only those securing other Senior Secured Debt) are acquired by any Grantor after the Issue Date (other than assets constituting Collateral that become subject to a Lien in favor of the Trustee upon acquisition thereof), such Grantor will cause such assets to the extent constituting Collateral to be subjected to a Lien securing the Notes Obligations and will take, and cause the Grantors to take, such actions as shall be necessary to grant and perfect such Liens; provided that, the Grantors shall only be required to cause such assets to be subject to a Lien securing the Notes Obligations if similar actions are required under the Credit Facilities to secure the obligations thereunder.

SECTION 12.04. After-Acquired Property.

If, at any time, a Restricted Subsidiary is required to become a Guarantor pursuant to Section 4.17 of this Indenture, such Restricted Subsidiary shall, at such time, promptly execute a joinder to the Security Documents and the Intercreditor Agreement, providing that such Restricted Subsidiary become a Grantor, to grant Liens on assets and pledge equity interests, in each case, that constitute Collateral to the applicable Notes Collateral Agent, in each case for the benefit of the Indenture Secured Parties (subject to the limitations set forth in this Indenture and other limitations set forth in the Security Documents and the Intercreditor Agreements), and if any Grantor acquires an asset that constitutes Collateral, such Grantor shall grant a Lien on such Collateral to the applicable Notes Collateral Agent for the benefit of the Indenture Secured Parties and perfect such Lien, subject in each case to the terms of the Security Documents and the Intercreditor Agreements.

107

SECTION 12.05. [Reserved].

SECTION 12.06. Post-Closing Obligations.

Notwithstanding anything contained herein, if, after the use by the Grantors of commercially reasonable efforts to perfect the Trustee’s first-priority security interest in the Collateral for the benefit of the Holders on the Issue Date, such first-priority security interest cannot be perfected on the Issue Date, then the Grantors shall take commercially reasonable efforts to perfect such first-priority security interest as promptly as practicable after the Issue Date and in any event within 90 days after the Issue Date.

SECTION 12.07. Release.

The Liens on assets of a Guarantor securing the Notes Obligations will be automatically released when such Guarantor’s Guarantee is released in accordance with the terms of this Indenture. In addition, the Liens securing the Notes Obligations will be released:

(a) in whole, upon satisfaction and discharge of this Indenture as described under Section 8.06 hereto;

(b) in whole, upon a Legal Defeasance or Covenant Defeasance as described under Article 8;

(c) in whole, upon payment in full of the principal of, and premium, if any, and accrued and unpaid interest on, all of the outstanding Notes;

(d) as permitted under Article 9;

(e) in part, as to any asset constituting Collateral (A) that is sold, transferred or otherwise disposed of by the Company, Holdings or any of the Guarantors (other than to the Company, Holdings or another Guarantor) in a transaction permitted pursuant to Section 4.10 hereof (to the extent of the Collateral sold, transferred or otherwise disposed of), (B) if the Credit Agreement Collateral Agent releases or will release its lien on such Collateral, simultaneously therewith unless such release occurs in connection with a discharge in full in cash of the Credit Facilities, which discharge is not in connection with a foreclosure of, or other exercise of remedies with respect to, Collateral by the Credit Facilities Secured Parties; (C) that is Net Proceeds used for any one or more purposes permitted pursuant to Section 4.10 hereof; (D) to the extent such Collateral is comprised of property leased to a Grantor, upon termination or expiration of such lease; or (E) otherwise in accordance with, and as expressly provided for under, this Indenture and the Security Documents;

(f) with respect to the Liens on the assets of a Guarantor, upon the designation of such Guarantor as an Unrestricted Subsidiary pursuant to the terms of this Indenture;

108

(g) with respect to the Liens on the assets of a Guarantor, if such Guarantor becomes an Immaterial Domestic Restricted Subsidiary that is not otherwise required to provide a Guarantee under Section 4.17 or ceases to be a Subsidiary;

(h) as set forth in the Intercreditor Agreement; or

(i) with respect to the Liens on any asset to the extent not constituting Collateral.

In the event that the Trustee or a Notes Collateral Agent is requested by the Company to execute any necessary or proper instrument or document to evidence or acknowledge the release, satisfaction or termination of any Lien securing the Notes Obligations, the Trustee or such Notes Collateral Agent, as applicable, shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel each stating that all conditions precedent under this Indenture, the Security Documents and the Intercreditor Agreement to such release have been complied with and that it is permitted for the Trustee and/or such Notes Collateral Agent to execute and deliver the instruments or documents requested by the Company in connection with such release. Any such instrument or document shall be prepared by the Company. Neither the Trustee nor the Notes Collateral Agents shall be liable for any such release undertaken in reliance upon any such Officers’ Certificate or Opinion of Counsel, and notwithstanding any term hereof or in any Security Document or in the Intercreditor Agreement to the contrary, neither the Trustee nor the Notes Collateral Agents shall be under any obligation to release any such Lien, or execute and deliver any such instrument or document of release, satisfaction or termination with respect thereto, unless and until it receives such Officers’ Certificate and Opinion of Counsel, upon which it shall be entitled to conclusively rely.

SECTION 12.08. Enforcement of Remedies.

Notwithstanding anything to the contrary herein, any enforcement of the Guarantees or any remedies with respect to the Collateral under the Security Documents is subject to the provisions of the Intercreditor Agreements.

SECTION 12.09. Compensation and Indemnification.

Each Notes Collateral Agent shall be entitled to the compensation and indemnification set forth in Section 7.07 hereof (with the references to the Trustee therein being deemed to refer to the Notes Collateral Agents and references to this Indenture therein being deemed to refer to this Indenture and the Security Documents) and subject to Section 12.01(e) hereof.

Beneficial interests 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 in 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”.

(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 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,

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, such 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 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 for interest in a Permanent Regulation S Global Note) or (iii) pursuant to an effective registration statement under the Act, in each case in accordance with any applicable securities laws of any state of the United States.

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 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 Note (including any Note represented by a Global Note) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Note for a certificated Note that does not bear the legend set forth above and rescind any restriction on the transfer of such 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).

(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.

6.000% SENIOR SECURED NOTES DUE 2033

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 6.000% per annum until maturity. The Company shall pay interest semi-annually on March 15 and September 15 of each year and at maturity, 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 September 15, 2024 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 March 15, 2025. 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 (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), if any, to the Persons who are registered Holders at the close of business on the March 1 or September 1 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; provided, however, that interest payable on the maturity date shall be paid to the Persons to whom the principal hereof is payable. The Notes will be payable as to principal, premium and interest 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 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 and premium 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. 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 September 19, 2024 (the “Indenture”) among the Company, Holdings, the Guarantors, The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”) and a notes collateral agent (the “US Collateral Agent”), and The Bank of New York Mellon, as a notes collateral agent (the “UK Collateral Agent”; each of the US Collateral Agent and the UK Collateral Agent, individually, a “Notes Collateral Agent” and, collectively, the “Notes Collateral Agents”). The terms of the Notes include those stated in the Indenture. 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. Optional Redemption.

Beginning on the Initial Redemption Date, 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 10 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 September 15 of the year set forth below:


Year	Percentage
2027		103.000	%
2028		101.500	%
2029 and thereafter		100.000	%

In addition, prior to September 15, 2027, 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 40% of the aggregate principal amount of the Notes (which includes Additional Notes, if any) originally issued at a redemption price (expressed as a percentage of principal amount) of 106.000%, plus accrued and unpaid interest, if any, to, but excluding, 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 by the Company is contributed to the equity capital of the Company); provided, however, that: (1) at least 60% 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.

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 September 15, 2027, 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, but excluding, 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 10 nor more than 60 days prior to the redemption date.

The Trustee shall have no responsibility with respect to the determination of any redemption price or Applicable Premium.

6. No Mandatory Redemption.

The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Notes.

7. 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 and unpaid 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 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 Secured 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 Secured 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 Secured 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, in accordance with the procedures set forth in the Indenture (or, in respect of such other Senior Secured Debt, such lesser price, if any, as may be provided for by the terms of such Senior Secured Debt). To

the extent that the aggregate amount of Notes or such other Senior Secured 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 Secured 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.

8. 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 10 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.

9. 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 notice of redemption is given 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.

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

11. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Guarantees, the Notes, any Security Document or the Intercreditor Agreement 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 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 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, a joinder to the Security Documents or the Intercreditor Agreement 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, to add assets to the Collateral or release Collateral from any Lien as permitted under the Indenture, to mortgage, pledge, hypothecate or grant any other Lien in favor of the Indenture Secured Parties, to provide extensions with respect to timing for, or modifications to the ministerial or administrative requirements for granting Liens, to the extent not prohibited under the Intercreditor Agreements and/or the Security Documents, to enter into intercreditor arrangements with respect to the Secured Debt or to provide for the succession of any parties to the Security Documents or the Intercreditor Agreement (and other amendments that are administrative or ministerial in nature) in connection with an amendment, renewal, extensions, substitution, refinancing, restructuring, replacement, supplementing or other modification to the Credit Facilities or other Secured Debt.

12. Defaults and Remedies. Events of Default include: (i) 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; (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); (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 under 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 then-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 $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; (vi) certain events of bankruptcy affecting the Company or any of its Significant Subsidiaries; and (vii) with respect to any Collateral having a fair market value in excess of $50 million, individually or in the aggregate, unless such Collateral has been released from the Liens in accordance with the provisions of the Indenture, the Security

Documents and the Intercreditor Agreement, (x) the security interest with respect to such Collateral under any Security Document or the Intercreditor Agreement shall fail to be in full force and effect, for any reason, and such failure should continue for 60 days or (y) the assertion by the Company or any Guarantor, in any pleading in any court of competent jurisdiction, that any security interest with respect to such Collateral under any Security Documents or the Intercreditor Agreement is invalid or unenforceable. 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, the Security Documents, the Intercreditor Agreement or the Notes except as provided in the Indenture, the Security Documents and the Intercreditor Agreement, as applicable. Subject to certain limitations, Holders of a majority in 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) 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 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.

13. Guarantee. The payment by the Company of the principal of, and premium and interest on, the Notes is fully and unconditionally guaranteed on a joint and several senior basis by Holdings and each of the Guarantors.

14. 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.

15. 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, the Indenture or the Security Documents 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.

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

17. 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).

18. 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. Requests may be made to:

19. Collateral and Security. The Notes and Guarantees will be secured by the Collateral on the terms and subject to the conditions set forth in the Indenture, the Intercreditor Agreement and the Security Documents. The Notes Collateral Agents will hold the Collateral for the benefit of the Indenture Secured Parties, in each case pursuant to the Indenture, the Security Documents and the Intercreditor Agreements. Each Holder, by accepting this Note, consents and agrees to the terms of the Indenture, the Security Documents (including the provisions providing for the foreclosure and release of Collateral) and the Intercreditor Agreements, as the same may be in effect or may be amended from time to time in accordance with their terms, and authorizes and directs each Notes Collateral Agent to enter into the Security Documents, as applicable, and the Intercreditor Agreements, and to perform its obligations and exercise its rights thereunder in accordance therewith.

The Company, Holdings and each Guarantor hereby designate the Notes Obligations and the Guarantees as “Designated Senior Debt” (as defined by the Indenture dated November 13, 2019, among the Company, Holdings, the subsidiary guarantors from time to time party thereto and The Bank of New York Mellon Trust Company, N.A., as Trustee, for the 2027 5.50% Notes), for all purposes of the 2027 5.50% Notes, the 2029 4.625% Notes and the 2029 4.875% Notes.
