Beneficial interests in the Temporary Regulation S Global Note will be exchanged for beneficial interests in a corresponding permanent global note substantially in the form of Exhibit A, including appropriate legends as set forth in Section 2.1(e) (the “Permanent Regulation S Global Note” and, together with the Temporary Regulation S Global Note, each a “Regulation S Global Note”), within a reasonable period after the expiration of the Restricted Period (as defined below) upon delivery of the certification contemplated by Section 2.7 and in accordance with the applicable procedures of DTC. Each Regulation S Global Note will be deposited upon issuance with, or on behalf of, the Trustee as custodian for DTC in the manner described in this Article II for credit to the respective accounts of the purchasers (or to such other accounts as they may direct), including, but not limited to, accounts at Euroclear or Clearstream.

Prior to the 40th day after the later of the commencement of the offering of the Initial Notes and the Issue Date (such period through and including such 40th day, the “Restricted Period”), interests in a Temporary Regulation S Global Note may only be transferred to Non-U.S. Persons pursuant to Regulation S, unless exchanged for interests in a Global Note in accordance with the transfer and certification requirements described herein.

The Regulation S Global Notes may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Regulation S Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or their nominee, as applicable, as hereinafter provided.

Initial Notes and Additional Restricted Notes that are resold to IAIs (the “Institutional Accredited Investor Notes”) in the United States of America shall be issued in the form of a permanent global note substantially in the form of Exhibit A, including appropriate legends as set forth in Section 2.1(e) (the “Institutional Accredited Investor Global Note”), deposited with the Trustee, as custodian for DTC, duly executed by the Issuers and authenticated by the Trustee as hereinafter provided. The Institutional Accredited Investor Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Institutional Accredited Investor Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as applicable, as hereinafter provided.

Initial Notes and Additional Restricted Notes resold to AIs in the United States of America shall be issued in the form of a Definitive Note substantially in the form of Exhibit A, including the legend as set forth in Section 2.1(e)(4) (each, an “Accredited Investor Note”).

The Rule 144A Global Notes, the Regulation S Global Notes and the Institutional Accredited Investor Global Note are sometimes collectively herein referred to as the “Global Notes.”

Investors may hold their interests in the Regulation S Global Note through organizations other than Euroclear or Clearstream that are participants in DTC’s system or directly through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations which are participants in such systems. If such interests are held through Euroclear or Clearstream, Euroclear and Clearstream will hold such interests in the applicable Regulation S Global Note on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. Such depositaries, in turn, will hold such interests in the applicable Regulation S Global Note in customers’ securities accounts in the depositaries’ names on the books of DTC.

The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of Paying Agent designated by the Issuers maintained for such purpose. The Issuers will maintain one or more Paying Agents for the Notes. The Bank of New York Mellon will initially act as the Principal Paying Agent; provided, however, that, at the option of the Paying Agent, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Notes Register or (ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC. Payments in respect of Notes represented by Definitive Notes (including principal, premium, if any, and interest) held by a Holder of at least $1,000,000, aggregate principal amount of Notes represented by Definitive Notes will be made by wire transfer to a U.S. Dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage, in addition to those set forth on Exhibit A and in Section 2.1(e). The Issuers shall approve any notation, endorsement or legend on the Notes. Each Note shall be dated the date of its authentication. The terms of the Notes set forth in Exhibit A are part of the terms of this Indenture and, to the extent applicable, the Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to be bound by such terms.

(d)             Denominations. The Notes shall be issuable only in minimum denominations of $2,000 and in integral multiples of $1.00 in excess thereof.

(e)             Restrictive Legends. Unless and until (i) an Initial Note or an Additional Note issued as a Restricted Note is sold under an effective registration statement, or (ii) the Trustee receives an Opinion of Counsel reasonably satisfactory to it stating that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act:

HOLDERS SHOULD CONTACT: ATTN: TREASURER, TRINSEO, GWATTSTRASSE 15, CH-8808 PFAEFFIKON SZ, SWITZERLAND.

(f)           Book-Entry Provisions. This Section 2.1(f) shall apply only to Global Notes deposited with the Trustee, as custodian for DTC.

(1)           Each Global Note initially shall bear legends as set forth in Section 2.1(e). Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to DTC, its successors or its respective nominees, except as set forth in Section 2.1(f)(4) and Section 2.1(g). If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global Note, the Notes Custodian will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

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

(3)           In connection with any transfer of a portion of the beneficial interest in a Global Note pursuant to Section 2.1(g) to beneficial owners who are required to hold Definitive Notes, the Notes Custodian shall reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Issuers shall execute, and the Trustee shall authenticate and make available for delivery, one or more Definitive Notes of like tenor and amount.

(4)           In connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 2.1(g), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuers shall execute, and the Trustee shall authenticate and make available for delivery, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations.

(5)           The registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

(6)           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 (ii) any holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry.

(g)             Definitive Notes. Except as provided below, owners of beneficial interests in Global Notes will not be entitled to receive Definitive Notes. Definitive Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Note if (A) DTC notifies the Issuers that it is unwilling or unable to continue as depositary for such Global Note or DTC ceases to be a clearing agency registered under the applicable law, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Issuers within 90 days of such notice, (B) the Issuers in their sole discretion execute and deliver to the Trustee and Registrar an Officer’s Certificate stating that such Global Note shall be so exchangeable or (C) an Event of Default has occurred and is continuing and the Registrar has received a written request from DTC. In the event of the occurrence of any of the events specified in the second preceding sentence or in clause (A), (B) or (C) of the preceding sentence, the Issuers shall promptly make available to the Trustee a reasonable supply of Definitive Notes. In addition, any Note transferred to an affiliate (as defined in Rule 405 under the Securities Act) of the Issuers or evidencing a Note that has been acquired by an affiliate in a transaction or series of transactions not involving any public offering must, until one year after the last date on which either the Issuers or any affiliate of the Issuers was an owner of the Note, be in the form of a Definitive Note and bear the legend regarding transfer restrictions in Section 2.1(e). If required to do so pursuant to any applicable law or regulation, beneficial owners may also obtain Definitive Notes in exchange for their beneficial interests in a Global Note upon written request in accordance with DTC’s and the Registrar’s procedures.

(1)           Any Definitive Note delivered in exchange for an interest in a Global Note pursuant to Section 2.1(f) shall, except as otherwise provided by Section 2.6(d), bear the applicable legend regarding transfer restrictions applicable to the Global Note set forth in Section 2.1(d).

(2)           If a Definitive Note is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such Definitive Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Definitive Note, the Issuers shall execute, and the Trustee shall authenticate and make available for delivery to the transferring Holder, a new Definitive Note representing the principal amount not so transferred.

(3)           If a Definitive Note is transferred or exchanged for another Definitive Note, (x) the Trustee will cancel the Definitive Note being transferred or exchanged, (y) the Issuers shall execute, and the Trustee shall authenticate and make available for delivery, one or more new Definitive Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Definitive Note (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Definitive Note, the Issuers shall execute, and the Trustee shall authenticate and make available for delivery to the Holder thereof, one or more Definitive Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Definitive Notes, registered in the name of the Holder thereof.

(4)           Notwithstanding anything to the contrary in this Indenture, in no event shall a Definitive Note be delivered upon exchange or transfer of a beneficial interest in the Temporary Regulation S Global Note prior to the end of the Restricted Period.

SECTION 2.2.       Execution and Authentication.

(a)           One Officer shall sign the Notes for each Issuer by manual or electronic signature. If the Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

(b)           A Note shall not be valid until an authorized signatory of the Trustee authenticates the Note by manual or electronic signature. The signature of the Trustee on a Note shall be conclusive evidence that such Note has been duly and validly authenticated and issued under this Indenture. A Note shall be dated the date of its authentication.

(c)           At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for delivery (1) Initial Notes issued on the Issue Date in an aggregate principal amount of $379,494,400 and from time to time, in accordance with the terms hereof, PIK Notes, (2) subject to the terms of this Indenture, Additional Notes for original issue in an unlimited principal amount and (3) under the circumstances set forth in Section 2.6(e), Initial Notes in the form of an Unrestricted Global Note, in each case upon a written order of each Issuer signed by one Officer (the “Issuer Order”). Such Issuer Order shall specify whether the Notes will be in the form of Definitive Notes or Global Notes, the amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, the Holder of the Notes and whether the Notes are to be Initial Notes or Additional Notes.

(d)           The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Issuers to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Responsible Officer of the Trustee, a copy of which shall be furnished to the Issuers. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

(e)           In case either Issuer or any Guarantor shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which either Issuer or any Guarantor shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to which such other Person assumes the obligations of such Issuer or Guarantor, as the case may be, hereunder, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may (but shall not be required), from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person with such changes in phraseology and form as may be appropriate to reflect such successor Person, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon the Issuer Order of the successor Person, shall authenticate and make available for delivery Notes as specified in such order for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section 2.2 in exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time outstanding for Notes authenticated and delivered in such new name.

SECTION 2.3.       Registrar and Paying Agent.

(a)           The Issuers or their agent shall maintain a register reflecting ownership of the Notes outstanding from time to time. The Issuers will also maintain a transfer agent. The initial transfer agent and registrar (the “Registrar”) will be, and the Issuers hereby appoint as transfer agent (the “Transfer Agent”), The Bank of New York Mellon. The Registrar shall keep a register of the Notes on behalf of the Issuers for so long as the Notes remain outstanding reflecting ownership of Notes outstanding from time to time and of their transfer and exchange (the “Notes Register”) and, upon written request from either of the Issuers or the Collateral Agent, the Registrar shall provide the Issuers or Collateral Agent, as applicable, with a copy of the Notes Register to enable them to maintain a register of the Notes at their offices. The Collateral Agent may request the Notes Register from the Registrar at any time and may rely on the most recently delivered Notes Register as true and correct until delivery of an otherwise updated Notes Register. The Issuers may have one or more co-Registrars and one or more additional Paying Agents. The Paying Agents will make payments on, and the Transfer Agents will facilitate transfer of, Notes on behalf of the Issuers. In the event that the Notes are no longer listed, the Issuers or their agent will maintain a register reflecting ownership of the Notes. The term “Paying Agent” includes any additional Paying Agent and the term “Registrar” includes any co-Registrar.

(b)           The Issuers shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuers shall notify the Trustee in writing of the name and address of each such agent. Any Issuer may act as Paying Agent, Registrar or Transfer Agent.

(c)           The Issuers initially appoint The Bank of New York Mellon as Paying Agent. The Issuers may change any Registrar, Paying Agent or Transfer Agent without prior notice to the Holders, but the Issuers shall provide written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of any appointment by a successor as evidenced by an appropriate agreement entered into by the Issuers and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee and the passage of any waiting or notice periods required by DTC procedures, or (ii) written notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuers and the Trustee.

SECTION 2.4.       Paying Agent to Hold Money in Trust. By no later than 10:00 a.m. (New York time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Issuers shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when due. The Issuers shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any, or interest on the Notes (whether such assets have been distributed to it by the Issuers or other obligors on the Notes), shall notify the Trustee in writing of any Default by the Issuers in making any such payment and shall during the continuance of any Default by the Issuers (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith deliver to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Notes together with a full accounting thereof. If either Issuer 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 Issuers at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds or assets disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than the Issuers or a Subsidiary of the Company) shall have no further liability for the money delivered to the Trustee.

(a)           A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by this Section 2.6. The Registrar will promptly register any transfer or exchange that meets the requirements of this Section 2.6 by noting the same in the Notes Register maintained by the Registrar for the purpose, and no transfer or exchange will be effective until it is registered in such Notes Register. The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section 2.6 and Section 2.1(f) and Section 2.1(g), as applicable, and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of DTC, Euroclear and Clearstream.

(1)           a registration of transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee in the form as set forth on the reverse of the Note that it is purchasing for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Issuers as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; provided that no such written representation or other written certification shall be required in connection with the transfer of a beneficial interest in the Rule 144A Global Note to a transferee in the form of a beneficial interest in that Rule 144A Global Note in accordance with this Indenture and the applicable procedures of DTC;

(2)           a registration of transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to an IAI or an AI shall be made upon receipt by the Registrar or its agent of a certificate substantially in the form set forth in Section 2.8 or Section 2.10, respectively, from the proposed transferee and the delivery of an Opinion of Counsel, certification and/or other information satisfactory to Issuers and the Registrar; and

(d)             Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not bearing a Restricted Notes Legend, the Registrar shall deliver Notes that do not bear a Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing a Restricted Notes Legend, the Registrar shall deliver only Notes that bear a Restricted Notes Legend unless (1) an Initial Note is being transferred pursuant to an effective registration statement, (2) Initial Notes are being exchanged for Notes that do not bear the Restricted Notes Legend in accordance with Section 2.6(e) or (3) there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to it stating that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. Any Additional Notes sold in a registered offering shall not be required to bear the Restricted Notes Legend.

(e)             Automatic Exchange from Global Note Bearing Restricted Notes Legend to Global Note Not Bearing Restricted Notes Legend. Upon the Issuers’ satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act, beneficial interests in a Global Note bearing the Restricted Notes Legend (a “Restricted Global Note”) may be automatically exchanged into beneficial interests in a Global Note not bearing the Restricted Notes Legend (an “Unrestricted Global Note”) without any action required by or on behalf of the Holder (the “Automatic Exchange”) at any time on or after the date that is the 366th calendar day after (1) with respect to the Notes issued on the Issue Date, the Issue Date or (2) with respect to Additional Notes, if any, the issue date of such Additional Notes or, in each case, if such day is not a Business Day, on the next succeeding Business Day (the “Automatic Exchange Date”). Upon the Issuers’ satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act, the Issuers shall (i) provide written notice to DTC and the Trustee at least fifteen (15) calendar days prior to the Automatic Exchange Date, instructing DTC to exchange all of the outstanding beneficial interests in a particular Restricted Global Note to the Unrestricted Global Note, which the Issuers shall have previously otherwise made eligible for exchange with DTC, (ii) provide prior written notice (the “Automatic Exchange Notice”) to each Holder at such Holder’s address appearing in the register of Holders at least fifteen (15) calendar days prior to the Automatic Exchange Date (the “Automatic Exchange Notice Date”), which notice must include (w) the Automatic Exchange Date, (x) the section of this Indenture pursuant to which the Automatic Exchange shall occur, (y) the “CUSIP” number of the Restricted Global Note from which such Holder’s beneficial interests will be transferred and (z) the “CUSIP” number of the Unrestricted Global Note into which such Holder’s beneficial interests will be transferred and (iii) on or prior to the Automatic Exchange Date, deliver to the Trustee for authentication one or more Unrestricted Global Notes, duly executed by the Issuers, in an aggregate principal amount equal to the aggregate principal amount of Restricted Global Notes to be exchanged into such Unrestricted Global Notes. At the Issuers’ written request on no less than five (5) calendar days’ notice prior to the Automatic Exchange Notice Date, the Trustee shall deliver, in the Issuers’ name and at their expense, the Automatic Exchange Notice to each Holder at such Holder’s address appearing in the register of Holders; provided that the Issuers have delivered to the Trustee the information required to be included in such Automatic Exchange Notice.

Notwithstanding anything to the contrary in this Section 2.6(e), during the fifteen (15) calendar day period prior to the Automatic Exchange Date, no transfers or exchanges other than pursuant to this Section 2.6(e) shall be permitted without the prior written consent of the Issuers. As a condition to any Automatic Exchange, the Issuers shall provide, and the Trustee shall be entitled to conclusively rely upon, an Officer’s Certificate and Opinion of Counsel to the Issuers to the effect that the Automatic Exchange shall be effected in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act and that the aggregate principal amount of the particular Restricted Global Note is to be transferred to the particular Unrestricted Global Note by adjustment made on the records of the Trustee, as custodian for DTC to reflect the Automatic Exchange. Upon such exchange of beneficial interests pursuant to this Section 2.6(e), the aggregate principal amount of the Global Notes shall be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC, to reflect the relevant increase or decrease in the principal amount of such Global Note resulting from the applicable exchange. The Restricted Global Note from which beneficial interests are transferred pursuant to an Automatic Exchange shall be canceled following the Automatic Exchange.

(f)           Retention of Written Communications. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.1 or this Section 2.6. The Issuers shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar.

(g)           Obligations with Respect to Transfers and Exchanges of Notes. To permit registrations of transfers and exchanges, the Issuers shall, subject to the other terms and conditions of this Article II, execute and the Trustee shall authenticate Definitive Notes and Global Notes at the Issuers’ and Registrar’s written request.

No service charge shall be made to a Holder for any registration of transfer or exchange, but the Issuers may require the Holder to pay a sum sufficient to cover any transfer tax assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon exchange or transfer pursuant to Section 2.2, Section 2.6, Section 2.11, Section 2.13, Section 4.5, Section 5.6 or Section 10.4).

The Issuers (and the Registrar) shall not be required to register the transfer of or exchange of any Note (A) for a period beginning (1) 15 calendar days before the mailing of a notice of an offer to repurchase or redeem Notes and ending at the close of business on the day of such mailing or (2) 15 calendar days before an Interest Payment Date and ending on such Interest Payment Date or (B) called for redemption, except the unredeemed portion of any Note being redeemed in part.

Prior to the due presentation for registration of transfer of any Note, the Issuers, the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name a Note is registered as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to paragraph 2 of the form of Note attached hereto as Exhibit A) interest on such Note and for all other purposes whatsoever, including without limitation the transfer or exchange of such Note, whether or not such Note is overdue, and none of the Issuers, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

Any Definitive Note delivered in exchange for an interest in a Global Note pursuant to Section 2.1(g) shall, except as otherwise provided by Section 2.6(d), bear the applicable legend regarding transfer restrictions applicable to the Definitive Note set forth in Section 2.1(e).

All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange.

(h)           No Obligation of the Trustee. None of the Trustee, the Paying Agent and the Registrar shall have any responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in, DTC or other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member, participant, member, beneficial owner or other Person (other than DTC) of any notice (including any notice of redemption or purchase) or the payment of any amount or delivery of any Notes (or other security or property) 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 in respect of the Notes shall be given or made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through DTC, subject to the applicable rules and procedures of DTC. The Trustee, any Paying Agent and any Registrar may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners.

None of the Trustee, the Paying Agent and the Registrar shall have any 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 DTC 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. Neither the Trustee nor any of its agents shall have any responsibility for any actions taken or not taken by DTC.

Upon transfer, the Notes would be registered in the name of the new beneficial owner as follows:

The undersigned represents and warrants to you that:

1.            We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)) purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Notes, and we are acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risk of our investment in the Notes and we invest in or purchase securities similar to the Notes in the normal course of our business. We and any accounts for which we are acting are each able to bear the economic risk of our or its investment.

2.            We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of original issue and the last date on which either Issuer or any affiliate of either Issuer was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Issuers or any Subsidiary thereof, (b) pursuant to an effective registration statement under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a “qualified institutional buyer” under Rule 144A of the Securities Act (a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales to Non-U.S. Persons that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Notes of $250,000 for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuers and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act.

Upon transfer, the Notes would be registered in the name of the new beneficial owner as follows:

The undersigned represents and warrants to you that:

1.            I am an “accredited investor” (as defined in Rule 501(a)(4) under the U.S. Securities Act of 1933, as amended (the “Securities Act”)) and I am acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. I have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risk of my investment in the Notes and I invest in or purchase securities similar to the Notes in the normal course of my business. I am able to bear the economic risk of my investment.

2.            I understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. I agree on my own behalf to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of original issue and the last date on which either Issuer or any affiliate of either Issuer was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Issuers or any Subsidiary thereof, (b) pursuant to an effective registration statement under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person I reasonably believe is a “qualified institutional buyer” under Rule 144A of the Securities Act (a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales to Non-U.S. Persons that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Notes of $200,000 for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of my property be at all times within my control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. Each purchaser acknowledges that the Issuers and the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant to clauses (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Issuers.

3.            I understand and acknowledge that upon the issuance thereof, and until such time as the same is no longer required under applicable requirements of the Securities Act or state securities laws, the Notes that I acquire will be certificated Notes that will bear, and all certificates issued in exchange therefor or in substitution thereof will bear, a restrictive legend set forth in Section 2.1(e) of the Indenture.

4.            I am an Affiliate of the Issuers.

SECTION 2.11.Mutilated, Destroyed, Lost or Stolen 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 Issuers shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Issuers and the Trustee that such Note has been lost, destroyed or wrongfully taken within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to the Issuers and the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee; provided, however, if after the delivery of such replacement Note, a protected purchaser of the Note for which such replacement Note was issued presents for payment or registration such replaced Note, the Trustee and/or the Issuers shall be entitled to recover such replacement Note from the Person to whom it was issued and delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security and/or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuers or the Trustee in connection therewith. Such Holder shall furnish security and/or indemnity sufficient in the judgment of the Trustee and the Issuers to protect them from any loss which any of them may suffer from any claim, loss, cost or liability resulting from such lost or stolen Note, and, in the absence of notice to the Issuers, any Guarantor or the Trustee that such Note has been acquired by a protected purchaser, the Issuers shall execute, and upon receipt of an Issuer Order, the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Issuers in their discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section 2.11, the Issuers may require that such Holder pay a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel and of the Trustee) in connection therewith.

Subject to the proviso in the initial paragraph of this Section 2.11, every new Note issued pursuant to this Section 2.11, in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuers, any Guarantor (if applicable) and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 2.11 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.12.Outstanding Notes

Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those paid pursuant to Section 2.11 and those described in this Section as not outstanding. A Note does not cease to be outstanding in the event either Issuer or an Affiliate of either Issuer holds the Note; provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 13.5 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Notes are present at a meeting of Holders of Notes for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Notes which a Responsible Officer of the Trustee actually knows to be held by either Issuer or an Affiliate of either Issuer shall not be considered outstanding.

If a Note is replaced pursuant to Section 2.11 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement pursuant to Section 2.11.

If the Paying Agent 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 accrued interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.13.Temporary Notes

In the event that Definitive Notes are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Issuers may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry all rights, of Definitive Notes but may have variations that the Issuers consider appropriate for temporary Notes. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate Definitive Notes. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at any office or agency maintained by the Issuers for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuers shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Notes.

SECTION 2.14.Cancellation

The Issuers 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 all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Notes in accordance with its internal policies and customary procedures (subject to the record retention requirements of the Exchange Act and the Trustee). If the Issuers or any Guarantor acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.14. The Issuers may not issue new Notes to replace Notes they have paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, transferred, redeemed, repurchased or canceled, such Global Note shall be returned by DTC to the Trustee 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 Definitive Notes, transferred in exchange for an interest in another Global Note, redeemed, repurchased 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 Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction.

SECTION 2.15.Payment of Interest; Defaulted Interest

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the regular record date for such payment at the office or agency of the Issuers maintained for such purpose pursuant to Section 2.3. From the Issue Date through and including the sixth Interest Payment Date following the Issue Date, the Issuers shall pay interest as follows: (a) 5.125% per annum in cash plus (b) 2.50% per annum of the stated interest either (i) by increasing the principal amount of the outstanding Notes, or (ii) issuing Additional Notes, unless the Issuers elect to instead pay such 2.50% per annum in cash. Thereafter until maturity, the entire 7.625% per annum shall be payable in cash.

Any interest on any Note which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days, shall forthwith cease to be payable to the Holder on the regular record date, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Issuers, at their election in each case, as provided in clause (a) or (b) below:

(a)           The Issuers may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Section 2.15(a). Thereupon the Issuers shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which date shall be not more than 20 calendar days and not less than 15 calendar days prior to the Special Interest Payment Date and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The Issuers shall promptly notify the Trustee in writing of such Special Record Date, and in the name and at the expense of the Issuers, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 13.1, not less than 10 calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the provisions in Section 2.15(b).

(b)           The Issuers may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Issuers to the Trustee of the proposed payment pursuant to this Section 2.15(b), such manner of payment shall be deemed practicable by the Trustee.

(c)           The Company shall make payments of interest in accordance with the provisions of Section 1 and Section 2 of the Notes. In connection with the payment of any interest in kind, (x) if the Notes are represented by one or more Definitive Notes, by issuing additional Definitive Notes to the relevant record Holder on the relevant Interest Payment Date (the “PIK Notes”) in an aggregate principal amount equal to the relevant amount of interest to be paid in kind (rounded up to the nearest $1.00) and the Trustee will, upon receipt of an Issuer Order, authenticate and deliver such PIK Notes in the form of Definitive Notes for original issuance to the Holders on the relevant record date, as shown by the records of the Registrar and (y) if the Notes are represented by one or more Global Notes registered in the name of, or held by, DTC or its nominee on the relevant record date, by increasing the principal amount of the outstanding Global Note by an amount equal to the amount of in-kind interest for the applicable interest period (rounded up to the nearest $1.00), and the Trustee, upon receipt of an Issuer Order, will increase the principal amount of the outstanding Global Note by such amount. The issuance of any PIK Notes to any Holder shall be computed on the basis of the aggregate principal amount of the Notes held by such Holder. Any PIK Notes issued as Definitive Notes shall be dated as of the applicable Interest Payment Date and shall bear interest from and after such date. All PIK Notes shall be governed by, and subject to the terms, provisions and conditions of, this Indenture and shall have the same rights and benefits as the Notes issued on the initial issue date of such Notes. Any PIK Notes shall be issued with the description “PIK Note” on the face of such Note. References in this Indenture and the Notes to the “principal amount” of the Notes shall include any increase in the principal amount of the outstanding Notes as a result of any payment of interest in kind. The Notes issued on the initial issue date, any increase in the balance of such Notes in connection with the payment of any interest in-kind and any PIK Notes shall be treated as a single class for all purposes under this Indenture. Following an increase in the principal amount of the outstanding Global Notes as a result of a payment of interest in kind, the Global Notes shall bear interest on such increased principal amount from and after the date of such payment.

Subject to the foregoing provisions of this Section 2.15, each Note delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

SECTION 2.16.CUSIP and ISIN Numbers

The Issuers in issuing the Notes may use “CUSIP” and “ISIN” numbers and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in notices of redemption or purchase 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 or purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or purchase shall not be affected by any defect in or omission of such CUSIP and ISIN numbers. The Issuers shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

ARTICLE III

AFFIRMATIVE COVENANTS

SECTION 3.1.Payment of Notes.

(a)           The Issuers shall promptly pay the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes and in this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if by 10:00 a.m. New York time on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal, premium, if any, and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. PIK Interest shall be considered paid on the date due if on such date the Trustee has received (i) an Issuer Order, pursuant to Section 2.2 hereof, from the Issuers signed by an Officer of each Issuer to increase the balance of the outstanding Global Notes to reflect such PIK Interest or (ii) a PIK Note duly executed by the Issuers together with an Issuer Order, pursuant to Section 2.2 hereof, of each Issuer signed by an Officer of each Issuer requesting the authentication of such PIK Notes by the Trustee.

(b)           The Issuers shall pay interest on overdue principal at the rate specified therefor in the Notes, and they shall pay interest on overdue installments of interest at the same rate to the extent lawful.

Notwithstanding anything to the contrary contained in this Indenture, the Issuers may, to the extent they are required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder.

(c)      (1)      All payments that the Issuers make under or with respect to the Notes and that any Guarantor makes under or with respect to any Note Guarantee will be made free and clear of, and without withholding or deduction for or on account of, any Taxes imposed or levied by or on behalf of the United States, any jurisdiction in which either Issuer or any Guarantor is incorporated, organized or otherwise resident for tax purposes or from or through which any of the foregoing makes any payment on the Notes or by or within any department or political subdivision or Governmental Authority or in any of the foregoing having the power to tax (each, a “Relevant Taxing Jurisdiction”), unless withholding or deduction is then required by law or by the official interpretation or administration of law. If either Issuer or any Guarantor is required to withhold or deduct any amount for or on account of Taxes of a Relevant Taxing Jurisdiction from any payment made under or with respect to the Notes, such Issuer or such Guarantor, as the case may be, will pay additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by each Holder or beneficial owner of the Notes (including Additional Amounts) after such withholding or deduction will be not less than the amount the Holder or beneficial owner would have received if such Taxes had not been required to be withheld or deducted.

(d)            Neither Issuer nor any Guarantor will pay Additional Amounts to a Holder or beneficial owner of Notes in respect or on account of:

(1)            any Taxes that would not have been imposed or levied by a Relevant Taxing Jurisdiction but for the holder’s or beneficial owner’s present or former connection with such Relevant Taxing Jurisdiction (other than the mere receipt or holding of Notes or by reason of the receipt of payments thereunder or the exercise or enforcement of rights under the Notes, this Indenture or any Note Guarantee);

(2)            any Taxes that are imposed or withheld by reason of the failure of the Holder or beneficial owner of Notes to (i) comply with any certification or identification requirements, whether required or imposed by statute, regulation or administrative practice of a Relevant Taxing Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Relevant Taxing Jurisdiction (including, without limitation, a certification that the holder or beneficial owner is not resident in the Relevant Taxing Jurisdiction), but in each case only to the extent that the holder or beneficial owner, as the case may be, is legally entitled to provide such certification or (ii) provide an IRS Form W-9 or applicable IRS Form W-8 (together with any required attachments and including any successor forms;

(3)            any Taxes imposed by reason of such holder's past or present status as the actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of Trinseo US Holding, Inc. entitled to vote;

(4)            any Taxes imposed on a holder by reason of its past or present status as a bank that acquired the Notes in consideration for an extension made pursuant to a loan agreement entered into in the ordinary course of its trade or business;

(5)            any estate, inheritance, gift, sales, transfer, personal property or similar Taxes;

(6)            any Tax which is payable otherwise than by deduction or withholding from payments made under or with respect to the Notes;

(7)            any Tax imposed on or with respect to any payment by the Issuers or a Guarantor to the holder if such holder is a fiduciary or partnership or person other than the sole beneficial owner of such payment to the extent that Taxes would not have been imposed on such payment had the beneficiary, partner or other beneficial owner directly held the Note;

(8)            any Tax that is imposed or levied by reason of the presentation (where presentation is required in order to receive payment) of the Notes for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever is later, except to the extent that the beneficial owner or holder thereof would have been entitled to Additional Amounts had the Notes been presented for payment on any date during such 30 day period;

(9)            any Tax that is imposed or levied on or with respect to a Note presented for payment on behalf of a holder or beneficial owner who would have been able to avoid such withholding or deduction by presenting the relevant Note to another Paying Agent in a member state of the European Union or the United Kingdom; or

(10)          any U.S. backup withholding taxes;

(11)          any Tax due pursuant to the Luxembourg law of 23 December 2005, as amended, introducing a withholding tax on certain interest payments to Luxembourg resident individuals; or

(12)          any withholding or deduction imposed pursuant to FATCA.

(e)           The Issuers and each Guarantor will (i) make such withholding or deduction required by applicable law and (ii) remit the full amount deducted or withheld to the relevant taxing authority in accordance with applicable law.

(f)            Upon request, the Issuers or the relevant Guarantor will take reasonable efforts to furnish to the Trustee or a holder within a reasonable time certified copies of tax receipts evidencing the payment by the Issuers or such Guarantor, as the case may be, of any Taxes imposed or levied by a Relevant Taxing Jurisdiction.

(g)           If, notwithstanding the reasonable efforts of the Issuers or such Guarantor to obtain such receipts, the same are not obtainable, then the Issuers or such Guarantor will provide such holder with other evidence reasonably satisfactory to the holder of such payment by the Issuers or such Guarantor.

(h)           The Issuers and each Guarantor shall pay (i) any present or future stamp, issue, registration, court documentation, excise or property taxes or other similar taxes, charges and duties, including interest and penalties with respect thereto, imposed by any Relevant Taxing Jurisdiction in respect of the execution, issue, delivery or registration of the Notes, any Note Guarantee or this Indenture or any other document or instrument referred to thereunder or hereunder and any such taxes, charges, duties or similar levies imposed by any jurisdiction as a result of, or in connection with, the enforcement of the Notes, such Note Guarantee or this Indenture or any such other document or instrument following the occurrence of any Event of Default with respect to the Notes, and (ii) any stamp, court, or documentary taxes (or similar charges or levies) imposed by any Relevant Taxing Jurisdiction with respect to the receipt of any payments with respect to the Notes or such Note Guarantee. Neither the Issuers nor any Guarantor will, however, pay such amounts that are (a) imposed on or result from a sale or other transfer or disposition by a Holder or beneficial owner of a Note, or (b) any registration duties due in Luxembourg in case of voluntary registration (présentation à l’enregistrement) of the Notes, any Note Guarantee or this Indenture or any other document or instrument referred to thereunder or hereunder, by a Holder or beneficial owner of a Note with the Registration, Estates and VAT Department (Administration de l’enregistrement, des domaines et de la TVA) in Luxembourg or where such registration is not required to establish, maintain, preserve or enforce the rights of the Holder.

(i)            Section 3.1(c) through (j) will survive any termination, defeasance or discharge of this Indenture and shall apply mutatis mutandis to any jurisdiction in which any successor person to the Issuers or any Guarantor is organized, incorporated or otherwise resident for tax purposes and any political subdivision or taxing authority or agency thereof or therein.

(j)            At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable (unless such obligation to pay Additional Amounts arises after the 30th day prior to the date on which payment under or with respect to the Notes is due and payable, in which case it will be promptly thereafter), if the Issuers will be obligated to pay Additional Amounts with respect to such payment, the Issuers will deliver to the Trustee an Officer’s Certificate stating that such Additional Amounts will be payable and the amounts so payable and setting forth such other information (other than the identities of Holders and beneficial owners) as is necessary to enable the Trustee or Paying Agent, as the case may be, to pay such Additional Amounts to the Holders of such Notes on the payment date.

SECTION 3.2.Reports.

(a)            Whether or not required by the SEC, so long as any Notes are outstanding, if not filed electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis, and Retrieval System (or any successor system) (“EDGAR”), the Company will furnish to the Holders of the Notes, within fifteen (15) days after the time periods specified below:

(1)            all financial information of Trinseo PLC that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K (or Form 6-K and Form 20-F if Trinseo PLC were a “foreign private issuer” as such term is defined under the rules and regulations of the SEC), if Trinseo PLC were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by Trinseo PLC’s certified independent accountants, within, in the case of annual information, 120 days after the end of each fiscal year and within, in the case of quarterly information, 60 days after the end of each of the first three fiscal quarters of each fiscal year; and (2)            as promptly as provided in the SEC’s rules and regulations, all current reports that would be required to be filed with the SEC on Form 8-K (or Form 6-K if Trinseo PLC was a “foreign private issuer” as such term is defined under the rules and regulations of the SEC) if Trinseo PLC were required to file such reports;

in each case, in a manner that complies in all material respects with the requirements specified in such form. To the extent any such information is not so filed or furnished, as applicable, within the time periods specified above and such information is subsequently filed or furnished, as applicable, the Company will be deemed to have satisfied its obligations with respect thereto at such time and any Default with respect thereto shall be deemed to have been cured. In addition, to the extent not satisfied by the foregoing, the Company agrees that, for so long as any Notes are outstanding, it will furnish to Holders and to securities analysts and prospective purchasers, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(b)           Substantially concurrently with the furnishing or making such information available to the Holders pursuant to Section 3.2(a), unless otherwise made available on EDGAR, the Company shall also post copies of such information required by Section 3.2(a) on a website (which may be nonpublic and may be maintained by the Company or a third party) to which access will be given to Holders, prospective purchasers of the Notes (which prospective purchasers shall be limited to “qualified institutional buyers” within the meaning of Rule 144A of the Securities Act or non-U.S. persons (as defined in Regulation S under the Securities Act) that certify their status as such to the reasonable satisfaction of the Company), and securities analysts and market making financial institutions that are reasonably satisfactory to the Company; provided, further, that such Holders, prospective investors, security analysts or market makers will agree to (1) treat all such reports (and the information contained therein) and information as confidential, (2) not use such reports (and the information contained therein) and information for any purpose other than their investment or potential investment in the Notes and (3) not publicly disclose or distribute any such reports (and the information contained therein) and information.

(c)           The Company may satisfy its obligations set forth in Sections 3.2(a) and (b) by furnishing reports relating to any parent entity or holding company of Trinseo PLC (including by making such reports available through EDGAR).

(d)           The Company will also hold quarterly conference calls for the Holders of the Notes to discuss financial information for the previous quarter; it being understood that such quarterly conference call may be the same conference call as with the lenders under any Credit Facility (if applicable) or with any equity investors of the Company’s (or any Parent’s) and analysts. In the event the Company (or any Parent) does not hold any such conference call for equity investors and analysts, the conference call for the Holders of the Notes will be held following the last day of each fiscal quarter of the Company and the Company will use its commercially reasonable efforts to cause such call to be held not later than ten (10) Business Days from the time that the Company distributes the financial information as set forth in Section 3.2(b). The Company will issue a press release announcing the time and date of such conference call and providing instructions for Holders, securities analysts and prospective investors to obtain access to such call.

(e)           Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

SECTION 3.3.Maintenance of Office or Agency. The Issuers will maintain an office or agency where the Notes may be presented or surrendered for payment, where, if applicable, the Notes may be surrendered for registration of transfer or exchange and where notices to or upon the Issuers in respect of the Notes and this Indenture may be delivered. The Corporate Trust Office of the Trustee shall be such office or agency of the Issuers, unless the Issuers shall designate and maintain some other office or agency for one or more of such purposes. The Issuers will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuers shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office of the Trustee, and the Issuers hereby appoint the Trustee as their agent to receive all such presentations and surrenders.

The Issuers 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 any such designation. The Issuers will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

SECTION 3.4.Corporate Existence. Except as otherwise provided in this Article III, Article IV and Section 10.2(b), the Issuers will do or cause to be done all things necessary to preserve and keep in full force and effect their legal existence and the corporate, partnership, limited liability company or other existence of each Restricted Subsidiary and the rights (charter and statutory), licenses and franchises of the Issuers and each Restricted Subsidiary; provided, however, that the Issuers shall not be required to preserve any such right, license or franchise or the corporate, partnership, limited liability company or other existence of any Restricted Subsidiary if the respective Board of Directors or, with respect to a Restricted Subsidiary that is not a Significant Subsidiary (or group of Restricted Subsidiaries that taken together would not be a Significant Subsidiary), senior management of the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and each of its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not, and will not be, disadvantageous in any material respect to the Holders.

SECTION 3.5.Payment of Taxes. Each Issuer shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all material taxes, assessments and governmental charges levied or imposed upon it or any of its Subsidiaries; provided, however, that the Issuers shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which appropriate reserves, if necessary (in the good faith judgment of management of the relevant Issuer), are being maintained in accordance with GAAP or where the failure to effect such payment will not be disadvantageous to the Holders.

SECTION 3.6.Payments for Consent. The Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, the Notes or the Note Guarantees unless such consideration is offered to be paid and is paid to all holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

SECTION 3.7.Compliance Certificate. The Issuers shall deliver to the Trustee within 120 days after the end of each fiscal year of the Issuers an Officer’s Certificate, one of the signers of which shall be the principal executive officer, principal financial officer or principal accounting officer of the Company, stating that in the course of the performance by the signer of his or her duties as an Officer of the Company he or she would normally have knowledge of any Default or Event of Default and whether or not the signer knows of any Default or Event of Default that occurred during the previous fiscal year; provided that no such Officer’s Certificate shall be required for any fiscal year ended prior to the Issue Date. If such Officer does have such knowledge, the certificate shall describe the Default or Event of Default, its status and the action the Issuers are taking or propose to take with respect thereto.

SECTION 3.8.Statement by Officers as to Default. Each Issuer shall deliver to the Trustee, as soon as possible and in any event within 30 days after the Issuers become aware of the occurrence of any Default or Event of Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the actions which the Issuers are taking or propose to take with respect thereto.

SECTION 3.9.Additional Collateral. Subject to the Intercreditor Agreements, at the Issuers’ expense, subject to the limitations and exceptions of this Indenture, including, without limitation, the provisions of the Collateral and Guarantee Requirement and any applicable limitation in any Collateral Document, the Issuers shall take all action necessary or reasonably requested by the Collateral Agent to ensure that the Collateral and Guarantee Requirement continues to be satisfied, including always ensuring that the obligations are secured by a second priority security interest in all Collateral, including, but not limited to, the Equity Interests of the Issuers and the Specified IP.

SECTION 3.10.Further Assurances. The Issuers shall, promptly upon reasonable request by the Collateral Agent (a) correct any material defect or error that may be discovered in the execution, acknowledgment, filing or recordation of any Collateral Document or other document or instrument relating to any Collateral, and (b) do, execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register any and all such further acts, deeds, certificates, assurances and other instruments as necessary from time to time in order to carry out more effectively the purposes of the Collateral Documents, to the extent required pursuant to the Collateral and Guarantee Requirement and subject to the Intercreditor Agreements.

Notwithstanding the foregoing, neither any Issuer nor any Guarantors shall be permitted to create, incur, assume, guarantee, suffer to exist or otherwise become directly or indirectly liable with respect to any LMT Indebtedness that is from or of a Subsidiary that is not a Guarantor (such creation, incurrence, assumption or guaranty being referred to as “Non-Guarantor LMT Indebtedness of Note Parties”) to the extent that any Indebtedness of any Issuer or any such Subsidiaries, together with any Non-Guarantor LMT Indebtedness of Note Parties, would or would reasonably be expected to result in two or more bankruptcy claims against the same Guarantor (including direct claims and indirect claims, such as through an intercompany claim in connection with a “double dip”), arising from one transaction or series of transactions relating to the same underlying Non-Guarantor LMT Indebtedness of Note Parties, unless each directly and adversely affected Holder has been offered an opportunity to fund or otherwise provide its pro rata share (based on the amount of Obligations that are adversely affected thereby held by each such Holder and calculated without regard to such Non-Guarantor LMT Indebtedness of Note Parties) of such Non-Guarantor LMT Indebtedness of Note Parties on the same terms as offered to all other such Holders (other than bona fide backstop or support fees and reimbursement of counsel and financial advisor fees and other expenses in connection with the negotiation of the terms of such transaction) pursuant to a written offer made to each such Holder describing the material terms of such Non-Guarantor LMT Indebtedness of Note Parties, which offer shall remain open to each such Holder for a period of not less than five Business Days; provided, however, that any such Holder may designate any of its Affiliates to provide such Non-Guarantor LMT Indebtedness of Note Parties on its behalf with the Obligations of such Holder being treated, for purposes hereof, as though such Holder had provided such Non-Guarantor LMT Indebtedness of Note Parties itself, without the written consent of each such Holder (the “Pro Rata Offer Exception”). Subject to the Pro Rata Offer Exception mutatis mutandis, any LMT Indebtedness that benefits from pari passu liens on any Collateral may not also benefit from guarantees from any subsidiary of any Issuer or any Subsidiary that is not a Guarantor.

For purposes of determining compliance with this Section 4.2, Indebtedness incurred under the Note Documents shall only be classified as incurred under Section 4.2(a).

The accrual of interest and the payment of interest in the form of additional Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.2. The principal amount of any non-interest bearing Indebtedness or other discount security constituting Indebtedness at any date shall be the principal amount thereof that would be shown on a balance sheet of the applicable Note Party dated such date prepared in accordance with GAAP.

(d)          The Issuers may provide in such notice of redemption that payment of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

SECTION 5.4.Effect of Notice of Redemption. Once notice of redemption is sent in accordance with Section 5.3 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. Notice of redemption may, at the Issuers’ option and discretion, be subject to one or more conditions precedent, as the case may be.

SECTION 5.5.Deposit of Redemption or Purchase Price.

(a)           By no later than 10:00 a.m. (New York time) on the redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date.

(b)          If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 3.1(a) hereof.

SECTION 5.6.Notes Redeemed or Purchased in Part. Upon surrender of a Note that is redeemed or purchased in part, the Issuers will issue and, upon receipt of an Issuer Order, the Trustee will authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered; provided that each such new Note will be in a minimum principal amount of $2,000 or integral multiples of $1.00 in excess thereof.

(b)           At any time and from time to time on or after January 17, 2026, the Issuers may redeem the Notes, in whole or in part, at a redemption price equal to the percentage of the principal amount of such Notes set forth below plus accrued and unpaid interest on the Notes redeemed, to, but not including, the applicable date of redemption, if redeemed during the twelve-month period beginning on January 17 of the year indicated below:

(c)           Unless the Issuers default in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(d)          Any redemption pursuant to this Section 5.7 shall be made pursuant to the provisions of Section 5.1 through Section 5.6.

(e)           If the optional redemption date is on or after an interest record date and on or before the related Interest Payment Date, the accrued and unpaid interest will be paid to the Person in whose name the Note is registered at the close of business on such interest record date, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the Issuers.

SECTION 5.8.Mandatory Redemption. Upon the occurrence of any event described in Section 2.05(b)(ii), (iii), (iv), (v) or (vi) of the Super HoldCo Credit Agreement as in effect as of the date hereof or Sections 13(c) and (d) of the Foreign Guaranty, the Issuers shall, within 10 Business Days thereafter, send a notice of redemption in accordance with this Article V setting a redemption date not later than 30 days after the date of such notice, redeem the Notes at par plus accrued and unpaid interest to but not including such redemption date; provided that until the obligations under the Super HoldCo Credit Agreement (other than contingent obligations) are paid in full in cash, the Issuers shall not be required pursuant to this Section to redeem the Notes. Subject to the Intercreditor Agreements, Issuers may at any time and from time to time purchase Notes in the open market or otherwise.

SECTION 5.9.Tax Redemption.

(a)           The Issuers may, at their option, redeem the Notes, in whole but not in part, at any time upon not less than 15 days’ nor more than 60 days’ notice to the Holders (which notice shall be given in accordance with the procedures described in Section 5.3), at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but not including, the redemption date, premium, if any, and all Additional Amounts, if any, then due and that will become due on the date of redemption as a result of the redemption or otherwise, if the Issuers determine in good faith that any Issuer or any Guarantor is, or on the next date on which any amount would be payable in respect of the Notes, would be obligated to pay Additional Amounts in respect of the Notes pursuant to the terms and conditions thereof, which such Issuer or such Guarantor, as the case may be, cannot avoid by the use of reasonable measures available to it (including, without limitation, making payment through a Paying Agent located in another jurisdiction), as a result of:

(1)            any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of any Relevant Taxing Jurisdiction affecting taxation that becomes effective on or after the Issue Date or, in the case of a Relevant Taxing Jurisdiction that arises after the Issue Date, the date on which such Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction under this Indenture (or, in the case of a successor Person, after the date of assumption by the successor person of the obligations thereunder); or

(2)            any change in the official application, administration, or interpretation of the laws, regulations or rulings of any Relevant Taxing Jurisdiction (including a holding, judgment, or order by a court of competent jurisdiction), on or after the Issue Date or, in the case of a Relevant Taxing Jurisdiction has changed since the Issue Date, the date on which such Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction under this Indenture (or, in the case of a successor Person, after the date of assumption by the successor person of the obligations thereunder) (each of Section 5.9(a)(1) and Section 5.9(a)(2), a “Change in Tax Law”).

(b)           Notwithstanding the foregoing, the Issuers may not redeem the Notes under this Section 5.9 if a Relevant Taxing Jurisdiction changes under this Indenture and the Issuers are obligated to pay Additional Amounts as a result of a Change in Tax Law of such Relevant Taxing Jurisdiction that was officially announced at the time the latter became a Relevant Taxing Jurisdiction.

(c)           In the case of a Guarantor that becomes a party to this Indenture after the Issue Date or a successor person (including a surviving entity), the Change in Tax Law must become effective after the date that such entity (or another person organized or resident in the same jurisdiction) becomes a party to this Indenture. In the case of Additional Amounts required to be paid as a result of the Issuers conducting business in any jurisdiction other than a Relevant Taxing Jurisdiction, the Change in Tax Law must become effective after the date the Issuers begin to conduct the business giving rise to the relevant withholding or deduction.

(d)          Notwithstanding the foregoing, no such notice of redemption will be given (i) earlier than 90 days prior to the earliest date on which the Issuers or any Guarantor would be obliged to make such payment of Additional Amounts or withholding if a payment in respect of the Notes or the relevant Note Guarantee, as the case may be, were then due and (ii) unless at the time such notice is given, the obligation to pay Additional Amounts remains in effect.

(e)          Unless the Issuers default in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(f)           The foregoing provisions shall apply mutatis mutandis to any successor Person, after such successor Person becomes a party to this Indenture, with respect to a Change in Tax Law occurring after the time such successor person becomes a party to this Indenture.

(A)            is for relief against the Company or any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together as of the latest audited consolidated financial statements for the Company, would constitute a Significant Subsidiary, in an involuntary case;

(B)            appoints a Custodian of the Company, any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together as of the latest audited consolidated financial statements for the Company, would constitute a Significant Subsidiary, for substantially all of its property;

(C)            orders the winding up or liquidation of the Company, any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together as of the latest audited consolidated financial statements for the Company, would constitute a Significant Subsidiary;

(E)            a Luxembourg Insolvency Event occurs in relation to the Company or any Guarantor organized under the laws of Luxembourg that is a Significant Subsidiary;

(10)            a Change of Control occurs; or

(11)            a Triggering Event occurs.

A Default under clauses (3), (4), (5) or (11) above will not constitute an Event of Default until the Trustee or the Holders of at least 30% in principal amount of the outstanding Notes notify the Issuers (and, in the case of notice from the Holders, the Trustee) of the Default and, with respect to clauses (3) and (5), the Issuers do not cure such Default within the time specified in clauses (3) or (5), as applicable, after receipt of such notice.

SECTION 6.2.Acceleration.

(a)          If an Event of Default (other than an Event of Default described in clause (8) or (9) of Section 6.1(a)) occurs and is continuing, (i) the Trustee by notice to the Issuers or (ii) the Holders of at least 30% in principal amount of the outstanding Notes by written notice to the Issuers and the Trustee, may declare the principal of, premium, if any, and accrued and unpaid interest on, all the Notes to be immediately due and payable as if the Notes were being redeemed on such date in accordance with Section 5.7. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately.

(b)          In the event of any Event of Default specified in clause (4) of Section 6.1(a) has occurred and is continuing, such Event of Default and all consequences thereof shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 30 days after such Event of Default arose:

(1)            (x) the Indebtedness that gave rise to such Event of Default shall have been discharged in full; or

(y)            the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default; or

(z)            if the default that is the basis for such Event of Default has been cured; and

(2)            (a) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction; and

(c)           all existing Events of Default, except nonpayment of principal, premium or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived.

If an Event of Default described in clause (8) or (9) of Section 6.1(a) occurs and is continuing,  the principal of, premium, if any, and accrued and unpaid interest on, all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders as if the Notes were being redeemed on such date in accordance with Section 5.7.

If the principal of, premium, and accrued and unpaid interest, if any, on the Notes becomes due and payable as provided above (an “Acceleration”), the principal of, and the premium, if any, and accrued but unpaid interest on the Notes that shall be due and payable in connection with any payment that occurs following such Acceleration shall equal the redemption price at such time, as if such Acceleration were an optional redemption of the Notes pursuant to Section 5.7 affected thereby on the date such amount is paid. Subject to applicable Law, the amount described in the preceding sentence is intended to be liquidated damages and not unmatured interest or a penalty. EACH OF THE ISSUERS AND THE GUARANTORS EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE REDEMPTION PRICE DESCRIBED ABOVE UPON ANY SUCH ACCELERATION. Each of the Issuers and the Guarantors expressly agrees (to the fullest extent that it may lawfully do so) that: (A) the redemption price is reasonable and is the product of an arm's length transaction between sophisticated business people, ably represented by counsel; (B) no portion of the redemption price described above shall constitute, or be deemed or considered to be, unmatured interest on the Notes or other amount and none of the Issuers or any Guarantor shall argue under any circumstance that the redemption price described above or any portion thereof constitutes unmatured interest on the Notes; (C) the redemption price described above shall be payable notwithstanding the then prevailing market rates at the time payment is made; (D) there has been a course of conduct between the Holders and the Issuers and the Guarantors giving specific consideration in this transaction for such agreement to pay the redemption price described above; (E) each of the Issuers and each Guarantor shall be estopped hereafter from claiming differently than as agreed to in this paragraph; and (F) in view of the impracticability and extreme difficulty of ascertaining actual damages, the Issuers and the Guarantors on the one hand, and each of the Holders, by holding the Notes, on the other hand, mutually agree that the redemption price described above is a reasonable calculation of the Holders' lost profits as a result of any such prepayments and is not a penalty. For the avoidance of doubt, the Issuers’ or any Guarantor’s payment of the redemption price described above shall not be in lieu of, or otherwise reduce or eliminate, the Issuers’ obligations to the Trustee, the Collateral Agent or any other agent under this Indenture or any other Note Documents.

SECTION 6.3.Other Remedies.

(a)           If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

(b)          The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.4.Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, (a) waive, by their consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), an existing Default or Event of Default and its consequences under this Indenture except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on a Note or (ii) a Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Holder affected and (b) rescind any acceleration with respect to the Notes and its consequences if (1) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (2) all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely because of the acceleration, (3) to the extent the payment of such interest is lawful, interest on overdue installments of interest, premium, if any, and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid, (4) the Issuers have paid the Trustee its compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances and (5) in the event of the cure or waiver of an Event of Default of the type described in clause (4) of Section 6.1(a), the Trustee shall have received an Officer’s Certificate and an Opinion of Counsel stating that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

SECTION 6.5.Control by Majority. The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place for conducting any proceeding for any remedy available to the Trustee or the Collateral Agent or for exercising any trust or power conferred on the Trustee or the Collateral Agent, subject to the Intercreditor Agreements. However, the Trustee or the Collateral Agent may refuse to follow any direction that conflicts with law, this Indenture, the Notes or the Intercreditor Agreements or, subject to Section 7.1 and Section 7.2, that the Trustee or the Collateral Agent determines is unduly prejudicial to the rights of other Holders or would subject the Trustee or the Collateral Agent to personal liability; provided, however, that the Trustee and the Collateral Agent may take any other action deemed proper by the Trustee or the Collateral Agent that is not inconsistent with such direction. Prior to taking any such action hereunder, the Trustee and the Collateral Agent shall be entitled to indemnification satisfactory to them against all fees, losses, liabilities and expenses (including attorney’s fees and expenses) that may be caused by taking or not taking such action.

SECTION 6.6.Limitation on Suits.

(a)            Subject to Section 6.7, a Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

(1)            such Holder has previously given the Trustee written notice that an Event of Default is continuing; (2)            Holders of at least 30% in principal amount of the outstanding Notes have requested in writing the Trustee to pursue the remedy;

(3)            such Holders have offered in writing to the Trustee security and/or indemnity satisfactory to the Trustee against any loss, liability or expense;

(4)            the Trustee has not complied with such request within 60 days after the receipt of the written request and the offer of security and/or indemnity; and

(5)            the Holders of a majority in principal amount of the outstanding Notes have not given the Trustee a written direction that is inconsistent with such request within such 60-day period.

(b)           A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

SECTION 6.7.Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture (including, without limitation, Section 6.6), the right of any Holder to receive payment of principal of, premium, if any, or interest on the Notes held by such Holder, on or after the respective due dates expressed or provided for in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.8.Collection Suit by Trustee. If an Event of Default specified in clause (1) or (2) of Section 6.1(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount then due and owing (together with interest on any unpaid interest and, if any, to the extent lawful) and the amounts provided for in Section 7.7.

SECTION 6.9.Trustee May File Proofs of Claim.

(a)           The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee or Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, their agents and their counsel) and the Holders allowed in any judicial proceedings relative to the Issuers, their Subsidiaries or their respective creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and the Collateral Agent and, in the event that the Trustee or the Collateral Agent shall consent to the making of such payments directly to the Holders, to pay to the Trustee or the Collateral Agent any amount due it for the compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, their agents and their counsel, and any other amounts due the Trustee under Section 7.7.

(b)          No provision of this Indenture shall be deemed to authorize the Trustee or the Collateral Agent to 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 thereof or to authorize the Trustee or the Collateral Agent to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10.Priorities.

(a)           Subject to the Intercreditor Agreements, if the Trustee or the Collateral Agent collects any money or property pursuant to this Article VI or, after an Event of Default, any money or other property distributable in respect of the Issuers’ obligations under this Indenture, it shall pay out the money or property in the following order:

(1)            FIRST: to the Trustee (including any predecessor trustee) and the Collateral Agent, and their agents and attorneys for amounts due to them under Section 7.7 of this Indenture or under any Note Document;

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

(3)            THIRD: to the Issuers, or to the extent the Trustee collects any amount for any Guarantor, to such Guarantor.

(b)          The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such record date, the Issuers shall send or cause to be sent to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid.

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 or the Collateral Agent for any action taken or omitted by it as Trustee or the Collateral Agent, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee or Collateral Agent, a suit by the Issuers, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Notes.

ARTICLE VII

TRUSTEE

SECTION 7.1.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 its exercise as a prudent person would use in the conduct of his or her own affairs.

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

(1)            the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture or the Notes, as the case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(c)           The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(1)            this Section 7.1(c) does not limit the effect of clause (b) of this Section 7.1;

The Trustee shall receive and retain financial reports and statements of the Company as provided herein, but shall have no duty to review or analyze such reports or statements to determine compliance with covenants or other obligations of the Company and shall not be deemed to have knowledge of any matter contained therein.

(b)           The Trustee need not investigate any fact or matter stated in the document. 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 Issuers, personally or by agent or attorney at the sole cost of the Issuers and shall Incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(c)           Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate and/or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officer’s Certificate or Opinion of Counsel.

(g)          The Trustee shall not be deemed to have notice of any Default or Event of Default or whether any entity or group of entities constitutes a Significant Subsidiary unless written notice of any event which is in fact such a Default or Event of Default or of any such Significant Subsidiary 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.

(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 to each agent, custodian and other Person employed to act hereunder.

(j)            The Trustee shall not be deemed to have knowledge of any fact or matter unless such fact or matter is known to a Responsible Officer of the Trustee.

(l)            The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, report, notice, request, direction, consent, order, bond, debenture, coupon 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, during business hours and upon reasonable notice, the books, records and premises of the Issuers and the Restricted Subsidiaries, personally or by agent or attorney, at the sole cost of the Issuers and shall Incur no liability or additional liability of any kind by reason of such inquiry or investigation.

SECTION 7.3.Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers, Guarantors or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-Registrar or co-Paying Agent may do the same with like rights. However, the Trustee must comply with Section 7.10 and Section 7.11. In addition, the Trustee shall be permitted to engage in transactions with the Issuers and their Affiliates and Subsidiaries; provided, however, that if the Trustee acquires any conflicting interest within the meaning of Section 310(b) of the TIA, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest or (ii) resign.

SECTION 7.4.Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity, sufficiency or adequacy of this Indenture, or the Notes, shall not be accountable for the Issuers’ use of the proceeds from the sale of the Notes, shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee or any money or proceeds paid to the Issuers pursuant to the terms of this Indenture and shall not be responsible for the recitals or any statement of the Issuers in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes, other than the Trustee’s certificate of authentication, and the Trustee assumes no responsibility for their correctness. The Trustee shall not be responsible to make any calculation with respect to any matter under this Indenture. The Trustee shall have no duty to monitor or investigate the Issuers’ compliance with or the breach of, or cause to be performed or observed, any representation, warranty, or covenant, or agreement of any Person, other than the Trustee, made in this Indenture.

SECTION 7.5.Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Responsible Officer has received written notice thereof, the Trustee shall send electronically or by first class mail to each Holder at the address set forth in the Notes Register notice of the Default or Event of Default within 60 days after receipt of such notice by a Responsible Officer. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest on any Note (including payments pursuant to the optional redemption or required repurchase provisions of such Note), the Trustee may withhold the notice if and so long it in good faith determines that withholding the notice is in the interests of Holders.

SECTION 7.6.Reports by Trustee to Holders. Within 60 days after each April 30 beginning April 30, 2025, the Trustee shall mail to each Holder a brief report dated as of such April 30 that complies with TIA Section 313(a) if and to the extent required thereby. The Trustee also shall comply with Trust Indenture Act Section 313(b)(2), to the extent applicable. The Trustee shall also transmit by mail all reports as required by Trust Indenture Act Section 313(c).

SECTION 7.7.Compensation and Indemnity.

(a)           The Company shall pay to the Trustee and the Collateral Agent from time to time such compensation, for their acceptance of this Indenture and services hereunder, as the parties shall agree in writing from time to time. The Trustee and Collateral Agent’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers and the Guarantors, jointly and severally, shall reimburse the Trustee and the Collateral Agent promptly upon request for all out-of-pocket disbursements, advances and expenses incurred or made by it in addition to the compensation for its services, including pursuant to the Collateral Agent Fee Letter. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel and the Collateral Agent’s agents and counsel.

(b)           The Issuers and the Guarantors, jointly and severally, shall indemnify the Trustee, the Collateral Agent and each of their officers, directors, employees, agents and any predecessor trustee and their respective officers, directors, employees and agents (the Trustee, the Collateral Agent and each such party, an “Indemnified Party”) for, and hold each Indemnified Party harmless against, any and all loss, damage, claims, liability or expense (including reasonable attorneys’ fees and expenses) incurred by any Indemnified Party in connection with the acceptance and administration of this trust and the performance of its duties hereunder (including the reasonable costs and expenses of enforcing this Indenture against the Issuers or any of the Guarantors (including this Section 7.7) or defending itself against any claim whether asserted by any Holder, any Issuer or any Guarantor or any holder of Pari Passu Indebtedness, or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder), including taxes (but excluding taxes imposed on such Persons in connection with compensation for such administration or performance). Each Indemnified Party shall notify the Company promptly of any claim for which it may seek indemnity. Failure by such Indemnified Party to so notify the Company shall not relieve the Issuers and the Guarantors of their obligations hereunder. The Company shall defend the claim and each Indemnified Party may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. Neither Issuer nor any Guarantor need reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee due to the Trustee’s own willful misconduct or negligence as determined by a final order of a court of competent jurisdiction. Neither Issuer nor any Guarantor need reimburse any expense or indemnify against any loss, liability or expense incurred by the Collateral Agent due to the Collateral Agent’s own willful misconduct or gross negligence as determined by a final order of a court of competent jurisdiction. Neither Issuer nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

(c)           The obligations of the Company under this Section 7.7 shall survive the satisfaction and discharge of this Indenture, the earlier resignation or removal of the Trustee or the Collateral Agent or the termination for any reason of this Indenture.

(d)          To secure the payment obligations of the Issuers and the Guarantors in this Section 7.7, the Trustee and the Collateral Agent shall have a Lien prior to the Notes on all money or property held or collected by the Trustee or Collateral Agent, except money or property held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture, the earlier resignation or removal of the Trustee or the Collateral Agent or the termination for any reason of this Indenture.

(e)          When the Trustee or the Collateral Agent Incurs expenses or renders services after an Event of Default specified in Section 6.1(a)(7) or Section 6.1(a)(8) hereof occurs, the expenses and the compensation for the services (including the reasonable fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.8.Replacement of Trustee.

(a)          The Trustee may resign at any time by so notifying the Issuers in writing not less than 30 days prior to the effective date of such resignation. The Holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the removed Trustee in writing not less than 30 days prior to the effective date of such removal and may appoint a successor Trustee with the Issuers’ written consent, which consent will not be unreasonably withheld. The Issuers shall remove the Trustee if:

(1)            the Trustee fails to comply with Section 7.10 hereof;

(2)            the Trustee is adjudged bankrupt or insolvent;

(3)            the Trustee has or acquires a conflict of interest that is not eliminated;

(c)           A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. 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, at the expense of the Issuers, promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.7.

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

(e)           If the Trustee fails to comply with Section 7.10, any Holder who has been a bona fide holder of a Note for at least six months may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f)            Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Issuers’ obligations under Section 7.7 shall continue for the benefit of the retiring Trustee. The predecessor Trustee shall have no liability for any action or inaction of any successor Trustee.

SECTION 7.9.Successor Trustee by Merger.

(a)          If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee.

(b)          In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall only apply to its successor or successors by merger, consolidation or conversion.

SECTION 7.10.Eligibility; Disqualification. This Indenture shall always have a Trustee that satisfies the requirements of TIA Sections 310(a)(1), (2) and (5) in every respect. The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuers are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

SECTION 7.11.Preferential Collection of Claims Against the Issuers. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated.

SECTION 7.12.FATCA Withholding.

(a)           Notwithstanding any other provision of this Indenture, the Trustee shall be entitled to make a deduction or withholding from any payment that it makes under this Indenture for or on account of any present or future taxes, duties or charges if and to the extent so required by FATCA, including by virtue of the relevant holder failing to satisfy any certification or other requirements under FATCA in respect of the Notes, in which event the Trustee shall make such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted, and shall have no obligation to gross up any payment hereunder or pay any additional amount as a result of such withholding tax.

(b)           The Issuers hereby covenant with the Trustee that they will provide the Trustee with sufficient information to enable the Trustee to determine whether or not the Trustee is obliged, in respect of any payments to be made by it pursuant to this Indenture, to make any withholding or deduction pursuant to FATCA.

SECTION 7.13.Trustee’s Application for Instruction from the Issuers. Any application by the Trustee for written instructions from the Issuers may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer of the Issuers actually receives such application, unless any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

ARTICLE VIII

COLLATERAL AND SECURITY

SECTION 8.1.Security Interest; Collateral Agent.

(a)           The due and punctual payment of the principal of, and accrued and unpaid interest on the Notes when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption, prepayment, demand or otherwise, and interest on the overdue principal of, and accrued and unpaid interest on, the Notes and payment and performance of all other obligations of the Issuers and the Guarantors to the Holders, the Trustee and the Collateral Agent under this Indenture, the Notes and the Note Guarantees, according to the terms hereunder or thereunder, are secured as provided in the Collateral Documents.

(b)          The Issuers consent and agree to be bound, and to cause the Guarantors to consent and agree to be bound by the terms of the Collateral Documents, as the same may be in effect from time to time, and agrees to perform its, and to cause the Guarantors to perform their, obligations thereunder in accordance therewith. The Issuers will and will cause each Guarantor to, do or cause to be done all such acts and things as may be required by the provisions of the Collateral Documents to assure and confirm to the Trustee that the Collateral Agent holds for the benefit of the Trustee and the Holders duly created, enforceable and perfected Liens as contemplated by the Collateral Documents or any part thereof, as from time to time constituted.

(c)           The Collateral Agent agrees that it will, subject to the Intercreditor Agreements, hold the Collateral created under the Collateral Documents to which it is a party as contemplated by this Indenture, and any and all proceeds thereof, for the benefit of the Holders and the Trustee, without limiting the Collateral Agent’s rights to act, when directed by the Required Holders, in preservation of the security interest in the Collateral. The Collateral Agent is authorized and empowered, when directed by the Required Holders, to appoint one or more co-Collateral Agents as may be necessary or appropriate; provided, however, that no Collateral Agent hereunder shall be personally liable by reason of any act or omission of any other Collateral Agent hereunder. Except as so directed, and only if indemnified to its reasonable satisfaction, the Collateral Agent will not be obligated:

(1)            to act upon direction purported to be delivered to it by any Person;

(2)            to foreclose upon or otherwise enforce any Lien created under the Collateral Documents; or

(3)            to take any other action whatsoever with regard to any or all of the Liens, Collateral Documents or Collateral.

The Collateral Agent will be accountable only for amounts that it actually receives as a result of the enforcement of the Liens or Collateral Documents.

(d)           In acting as Collateral Agent hereunder and under the Collateral Documents, the Collateral Agent shall be afforded, and shall be entitled to enforce, each and all of the rights, privileges, protections, immunities, indemnities and benefits of the Trustee in this Indenture and the other Note Documents, including, without limitation, under Article VII; provided that in that context any references in this Indenture to “Trustee” shall be references to “Collateral Agent”, and Section 7.1(a) does not apply to the Collateral Agent.

(e)           Neither the Trustee nor the Collateral Agent nor any of their respective officers, directors, employees, attorneys or agents shall:

(1)            be responsible or liable for the existence, genuineness, value or protection of any Collateral, for the legality, enforceability, effectiveness, or sufficiency of the Collateral Documents, for the creation, perfection, continuation, priority, sufficiency or protection of any Lien, including without limitation not being responsible for payment of any taxes, charges or assessments upon the Collateral or otherwise as to the maintenance of the Collateral, or for any defect or deficiency as to any such matters, or to monitor the status of any Lien or performance of the Collateral, or for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens or Collateral Documents or any delay in doing so. Neither the Trustee nor the Collateral Agent nor any of their respective officers, directors, employees, attorneys or agents will be responsible or liable for making any filings or recordings to perfect or maintain the perfection of the Collateral Agent’s Lien in the Collateral, including without limitation, the filing of any UCC financing statements, continuation statements, or any filings with respect to the U.S. Patent and Trademark Office or U.S. Copyright Office.

(f)           At all times when the Trustee is not itself the Collateral Agent, the Issuers will deliver to the Trustee copies of all Collateral Documents delivered to the Collateral Agent and copies of all documents delivered to the Collateral Agent pursuant to the Collateral Documents.

(g)           Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Collateral Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Collateral Documents, to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder, or any other party, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Collateral Documents, or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties.

(h)          No provision of this Indenture or any Collateral Document shall require the Collateral Agent to expend or risk its own funds or otherwise Incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders or the Trustee unless it shall have received indemnity reasonably satisfactory to the Collateral Agent against potential costs and liabilities incurred by the Collateral Agent relating thereto. Notwithstanding anything to the contrary contained in this Indenture or the Collateral Documents, in the event the Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies to acquire control or possession of the Collateral, the Collateral Agent shall not be required to commence any such action or exercise any remedy or take any such other action if the Collateral Agent has determined that the Collateral Agent may Incur personal liability as a result of the presence at, or release on or from, the Collateral or such property, of any hazardous substances unless the Collateral Agent has received security and/or indemnity from the Holders in an amount and in a form satisfactory to the Collateral Agent in its sole discretion, protecting the Collateral Agent from all such liability. The Collateral Agent shall at any time be entitled to cease taking any action described in this clause if it no longer reasonably deems any indemnity, security or undertaking from the Issuers or the Holders to be sufficient.

(i)            Subject to Section 8.4 hereof, in each case that the Collateral Agent may or is required hereunder to take any action (an “Action”), including without limitation to make any determination, to give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any Collateral Document, the Collateral Agent may seek direction from the Trustee or the Required Holders. Neither the Trustee nor the Collateral Agent shall be liable with respect to any Action taken or omitted to be taken by it in accordance with the direction from the Required Holders and any such action taken or omitted to be taken shall not be considered due to the Trustee’s or Collateral Agent’s gross negligence or willful misconduct in any respect. If the Trustee or the Collateral Agent shall request direction from the Required Holders with respect to any Action, the Trustee and the Collateral Agent shall be entitled to refrain from such Action unless and until the Trustee or Collateral Agent, as applicable, shall have received direction from the Required Holders, and neither the Trustee nor the Collateral Agent shall Incur liability to any Person by reason of so refraining.

(j)            The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee, a Holder or the Issuers referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default”. The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article VI or the Required Holders subject to this Article VIII.

(k)          The parties hereto and the Holders hereby agree and acknowledge that neither the Collateral Agent nor the Trustee shall assume, be responsible for or otherwise be obligated for any liabilities, claims, causes of action, suits, losses, allegations, requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs (including but not limited to, any remediation, corrective action, response, removal or remedial action, or investigation, operations and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, pursuant to any environmental law as a result of this Indenture, the Intercreditor Agreements, the Collateral Documents or any actions taken pursuant hereto or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that in the exercise of its rights under this Indenture, the Intercreditor Agreements and the Collateral Documents, the Collateral Agent and the Trustee may hold or obtain indicia of ownership primarily to protect the security interest of the Collateral Agent or the Trustee, as applicable, in the Collateral and that any such actions taken by the Collateral Agent or the Trustee shall not be construed as or otherwise constitute any participation in the management of such Collateral. In the event that the 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 obligation for the benefit of another, which in either the Collateral Agent’s or Trustee’s sole discretion may cause the Collateral Agent or Trustee, as applicable, 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 the Collateral Agent or Trustee, as applicable, to Incur liability under CERCLA or any other federal, state or local law, the Collateral Agent and the Trustee reserves 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 Collateral Agent 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 the Collateral Agent’s or the Trustee’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 property to be possessed, owned, operated or managed by any person (including the Collateral Agent or the Trustee) other than the Issuers, the Required Holders shall direct the Collateral Agent or the Trustee to appoint an appropriately qualified Person (excluding the Collateral Agent or the Trustee) who they shall designate to possess, own, operate or manage, as the case may be, the property.

(l)           Beyond the exercise of reasonable care in the custody thereof, neither the Trustee nor the Collateral Agent 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 Collateral Agent 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 Collateral Agent 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 the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee or the Collateral Agent, as applicable, in good faith.

(m)          Each successor Trustee may become the successor Collateral Agent as and when the successor Trustee becomes the Trustee.

(n)          The Collateral Agent shall be fully justified in failing or refusing to take any action under this Indenture, the Intercreditor Agreements or the Collateral Documents unless it shall be directed by the Trustee (acting at the direction of the Required Holders) or the Required Holders. If the Collateral Agent so requests, it shall first be indemnified to its satisfaction by the Holders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent and the Trustee shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture, the Intercreditor Agreements or the Collateral Documents in accordance with a request, direction, instruction, or consent of the Required Holders or, in the case of the Collateral Agent, at the request, direction, instruction, or consent of the Trustee (acting at the direction of the Required Holders) and any such action taken or omitted to be taken shall not be considered due to the Trustee’s or the Collateral Agent’s gross negligence or willful misconduct in any respect. Such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Holders.

(o)          Except as otherwise explicitly provided herein or in the Collateral Documents or the Intercreditor Agreements, the Collateral Agent, the Trustee nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof.

(p)          The Collateral Agent and the Trustee assumes no responsibility for any failure or delay in performance or any breach by the Issuers or any other grantor under this Indenture, the Intercreditor Agreements and the Collateral Documents. The Collateral Agent and the Trustee shall not have any obligation to any Holder or any other Person to ascertain or inquire into the existence of any Default or Event of Default, the observance or performance by any obligor of any terms of this Indenture, the Intercreditor Agreements or the Collateral Documents, or the satisfaction of any conditions precedent contained in this Indenture, the Intercreditor Agreements or any Collateral Documents. The Collateral Agent and the Trustee shall not be required to initiate or conduct any litigation or collection or other proceeding under this Indenture or the Collateral Documents.

(q)          Subject to the provisions of the applicable Collateral Documents and this Indenture, each Holder, by acceptance of the Notes, agrees that the Collateral Agent and the Trustee shall execute and deliver such Intercreditor Agreements as it may be presented from time to time and the Collateral Documents to which it is a party and all agreements, documents and instruments incidental thereto (including any releases permitted hereunder), and act in accordance with the terms thereof. For the avoidance of doubt, the Collateral Agent shall not be required to exercise discretion under this Indenture, the Intercreditor Agreements or the Collateral Documents and shall not be required to make or give any determination, consent, approval, request or direction without the Required Holders or the Trustee (acting at the direction of the Required Holders). Any such direction from the Required Holders to the Collateral Agent shall be facilitated through the Trustee.

SECTION 8.2.Authorization of Actions to be Taken by the Trustee or the Collateral Agent under the Collateral Documents.

(a)           Subject to the Intercreditor Agreements, the provisions of Section 8.1 and the terms of the Collateral Documents, the Trustee may (but shall have no obligation to), in its sole discretion and without the consent of the Holders, direct, on behalf of the Holders of Notes, the Collateral Agent to take all actions it deems necessary or appropriate in order to:

(1)            enforce any of the terms of the Collateral Documents and the Intercreditor Agreements; and

(2)            collect and receive any and all amounts payable in respect of the obligations of the Issuers and the Guarantors under this Indenture, the Notes, the Intercreditor Agreements and the Collateral Documents.

(b)          Subject to the provisions of this Indenture, the Intercreditor Agreements and the Collateral Documents, the Trustee and/or the Collateral Agent will have power to institute and maintain such suits and proceedings as it may deem expedient (or as directed by the Required Holders) to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of this Indenture, the Intercreditor Agreements or the Collateral Documents, and such suits and proceedings as may be necessary to preserve or protect the interests of the Trustee, the Collateral Agent and the interests of the Holders in the Collateral. The foregoing includes the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest under the Collateral Documents or be prejudicial to the interests of the Holders or of the Trustee and/or the Collateral Agent; provided, that neither the Collateral Agent nor the Trustee has any obligations to monitor or evaluate any proposed legislation, rule or order.

(c)           with respect to any Swiss law governed security interests “Swiss Security”:

(1)            the Collateral Agent (and any successor collateral agent) shall accept, hold, administer and, as the case may be, enforce or release: (A) any Swiss Security of accessory nature (akzessorische Sicherheiten); and (B) any proceeds of such Swiss Security, acting in its own name and as representative (direkter Stellvertreter) in the name and for the account of the Junior Lien Secured Parties (as defined in the Second Lien Intercreditor Agreement, the “Secured Parties”); (2)            the Collateral Agent (and any successor collateral agent) shall accept, hold, administer and, as the case may be, enforce or release: (A) any Swiss Security of non-accessory nature (nicht-akzessorische Sicherheiten); and (B) any proceeds of such Swiss Security, as fiduciary (treuhänderisch) in its own name but for the benefit of all Secured Parties;

(3)            each present and future Secured Party (other than the Collateral Agent) hereby appoints, instructs and authorises the Collateral Agent (and each successor collateral agent) to accept, hold, administer and, as the case may be, enforce or release the Swiss Security, and any proceeds of such Swiss Security as set out above and in the respective Collateral Document constituting the Swiss Security, and the Collateral Agent (and each successor collateral agent appointed from time to time) hereby accepts such appointment; and

(4)            each present and future Secured Party (other than the Collateral Agent) hereby instructs and authorises the Collateral Agent (and any successor collateral agent appointed from time to time) in its own name and/or in the name of such Secured Party as its representative (direkter Stellvertreter), as the case may be to give effect to this paragraph, to enter into, amend, replace, rescind or terminate any Collateral Document or other document constituting the Swiss Security, to exercise any rights and perform any obligations thereunder and to make and accept all declarations and take all actions it considers necessary or useful in connection with any Swiss Security on behalf of such Secured Party (other than the Collateral Agent).

SECTION 8.3.Authorization of Receipt of Funds by the Trustee under the Collateral Documents. Subject to the Intercreditor Agreements, the Trustee and/or the Collateral Agent is authorized to receive any funds for the benefit of the Collateral Agent and the Holders distributed under the Collateral Documents, and to make further distributions of such funds to the Holders according to the provisions of this Indenture with respect to the Collateral and such funds.

SECTION 8.4.Termination of Security Interest; Release of Collateral.

(a)          Subject to Section 8.4(b), Collateral will be released automatically from the Liens securing the Obligations of the Issuers and the Guarantors under this Indenture, the Notes, the Note Guarantees and the Collateral Documents without the consent or further action of any Person:

(1)            in whole or in part, as applicable, upon the sale, transfer, exclusive license, agreement or other disposition of such property or assets (including a disposition resulting from eminent domain, condemnation or similar circumstances) by the Issuers or any Guarantor to the extent permitted pursuant to this Indenture, the Intercreditor Agreements and the Collateral Documents; provided that, (x) solely to the extent that such transaction constitutes the sale, disposition of all or substantially all of the Issuers’ property and assets, in one transaction or a series of related transactions; and (y) solely to the extent that such transaction constitutes the sale, disposition of all or substantially all of a Guarantor’s property and assets, in one transaction or a series of related transactions; and that the Issuers have delivered to the Trustee and the Collateral Agent an Officer’s Certificate and Opinion of Counsel stating that such transaction complies with the provisions of this Section 8.4;

(2)            in whole or in part, as applicable, with the consent of the Holders of at least 66 2/3% in principal amount, the Notes then outstanding in accordance with Section 8.2, including consents obtained in connection with a tender offer or exchange offer, or purchase of Notes;

(3)            with respect to any Collateral securing the Note Guarantee, when such Guarantor is released in accordance with the terms of Section 10.2;

(4)            in whole or in part, as applicable, as to all or any portion of the Collateral which has been taken by eminent domain, condemnation or similar circumstances;

(5)            upon satisfaction and discharge of this Indenture as described in Article IX hereof; or (6)            in accordance with the applicable provisions of the Intercreditor Agreements or the Collateral Documents.

(b)           With respect to any release of the Liens on the Collateral as provided in Section 8.4(a) above, upon receipt of an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent under the Note Documents to such release or the entry into such agreements have been met and that the execution and delivery by the Trustee or the Collateral Agent of the documents requested by the Issuers in connection with such release or the entry into such agreements is authorized and expressly permitted by the Note Documents, and in the case of any release any appropriate instruments of termination, satisfaction, discharge or release prepared by the Issuers (in form and substance reasonably satisfactory to the Trustee and the Collateral Agent, without representation, recourse or warranty), the Trustee and the Collateral Agent shall execute, deliver or acknowledge (at the Issuers’ expense) such instruments or releases as are requested to evidence the release and discharge of any Collateral expressly permitted to be released pursuant to the Note Documents. Neither the Trustee nor the Collateral Agent shall have any duty or liability for determining the Issuers’ compliance with this Section 8.4, but instead may rely on the Officer’s Certificates and Opinion of Counsel issued by the Issuers under this Section 8.4. Notwithstanding any term hereof or in any Collateral Document or the Intercreditor Agreements to the contrary, the Trustee and the Collateral Agent shall not be under any obligation to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction, discharge or termination, unless and until such party receives such Officer’s Certificate and Opinion of Counsel.

(c)           The security interests granted under this Indenture and all Collateral Documents will terminate upon the full and final payment and performance of all obligations (other than contingent indemnification obligations for which no claim has been made) of the Issuers and any other obligors, if any and as applicable, under the Note Documents.

(d)          The release of any Collateral from the terms of the Collateral Documents shall not be deemed to impair the security under this Indenture or the Collateral Documents in contravention of the provisions hereof or affect the Lien of this Indenture or the Collateral Documents if and to the extent the Collateral is released pursuant to this Indenture or the Collateral Documents or upon the satisfaction and discharge of this Indenture. For the avoidance of doubt, the Issuers and the Guarantors shall not be required to comply with Section 314(d) of the Trust Indenture Act in connection with any release of Collateral. For the avoidance of doubt, the automatic release of any current assets constituting Collateral in connection with the sale, lease or other similar Disposition of such inventory of the Issuers and the Guarantors in the ordinary course of business shall not require delivery of any reports, certificates, opinions or other formal documentation.

(e)          Upon such release or any release of Collateral or any part thereof in accordance with the provisions of this Indenture, the Intercreditor Agreements or the Collateral Documents, upon the request and at the sole cost and expense of the Issuers and the Guarantors, the Trustee shall direct the Collateral Agent to and upon such request and direction, the Collateral Agent shall:

(1)            assign, transfer and deliver to the Issuers or the applicable Guarantor, as the case may be, against receipt and without recourse to, representation or warranty by the Collateral Agent except as to the fact that the Collateral Agent has not encumbered the released assets, such of the Collateral or any part thereof to be released as may be in possession of the Collateral Agent and as shall not have been sold or otherwise applied pursuant to the terms of the Collateral Documents;

(2)            consent to the Issuers’ filing of UCC financing statement amendments or releases (which shall be prepared by the Issuers or any Guarantor) to the extent necessary to delete such Collateral or any part thereof to be released from the description of assets in any previously filed financing statements; and

(3)            execute and deliver such documents, instruments or statements (which shall be prepared by the Issuers) and take such other action as the Issuers may request to cause to be released and reconveyed to the Issuers, or the applicable Guarantor, as the case may be, such Collateral or any part thereof to be released and to evidence or confirm that such Collateral or any part thereof to be released has been released from the Liens of each of this Indenture and each of the Collateral Documents.

Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Collateral Agent and appoint a successor Collateral Agent.

(b)          Any corporation or other entity into which the Collateral Agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Collateral Agent shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Collateral Agent (including the administration of this Indenture) shall be the successor to the Collateral Agent hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto.

SECTION 8.9.Acceptance by Collateral Agent. Any successor Collateral Agent appointed as provided in Section 8.7 shall execute, acknowledge and deliver to the Issuers and to its predecessor Collateral Agent an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Collateral Agent shall become effective and such successor Collateral Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Collateral Agent herein; but, nevertheless, on the written request of the Issuers or of the successor Collateral Agent, the Collateral Agent ceasing to act shall, at the expense of the Issuers and subject to payment of any amounts then due pursuant to the provisions of Section 7.7, execute and deliver an instrument transferring to such successor Collateral Agent all the rights and powers of the Collateral Agent so ceasing to act. Upon request of any such Collateral Agent, the Issuers shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor Collateral Agent all such rights and powers. Any Collateral Agent ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such Collateral Agent as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.7.

Upon acceptance of appointment by a successor Collateral Agent as provided in this Section 8.9, each of the Issuers and the successor Collateral Agent, at the written direction and at the expense of the Issuers, shall give or cause to be given notice of the succession of such Collateral Agent hereunder to the Holders in accordance with Section 13.1. If the Issuers fails to give such notice within ten (10) days after acceptance of appointment by the successor Collateral Agent, the successor Collateral Agent shall cause such notice to be given at the expense of the Issuers.

SECTION 8.10.Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article VIII upon the Issuers with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuers or of any Officer or Officers thereof required by the provisions of this Article VIII; and if the Trustee, Collateral Agent, or their nominee or agent, shall be in possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee, the Collateral Agent, or their nominee or agent.

ARTICLE IX

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 9.1.Option to Effect Legal Defeasance or Covenant Defeasance; Defeasance. The Issuers may, at their option and at any time, elect to have Section 9.2 or Section 9.3 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII.

SECTION 9.2.Legal Defeasance and Discharge.

(a)          Upon the Issuers’ exercise under Section 9.1 hereof of the option applicable to this Section 9.2, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 9.3 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 9.5 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all of their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuers, shall execute such instruments as requested by the Issuers acknowledging the same) and to have cured all then existing Events of Default, except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1)            the rights of Holders of Notes issued under this Indenture to receive payments in respect of the principal of, premium, if any, on the Notes when such payments are due solely out of the trust referred to in Section 9.3 hereof; (2)            the Issuers’ obligations with respect to the Notes under Article II concerning issuing temporary Notes, registration of such Notes, mutilated, destroyed, lost or stolen Notes and Section 2.11 hereof concerning the maintenance of an office or agency for payment and money for security payments held in trust;

(3)            the rights, powers, trusts, duties and immunities of the Trustee and the Issuers’ or Guarantors’ obligations in connection therewith; and

(4)            this Article VIII with respect to provisions relating to Legal Defeasance.

SECTION 9.3.Covenant Defeasance. Upon the Issuers’ exercise under Section 9.1 hereof of the option applicable to this Section 9.3, the Note Parties will, subject to the satisfaction of the conditions set forth in Section 9.4 hereof, be released from each of their obligations under Section 3.2, Section 3.7, Section 3.8, Section 3.9, Section 3.10 and Article IV hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 9.4 hereof are satisfied (hereinafter, Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 9.1 hereof of the option applicable to this Section 9.3, subject to the satisfaction of the conditions set forth in Section 9.4, Section 6.1(a)(3), Section 6.1(a)(4), Section 6.1(a)(5), Section 6.1(a)(6), Section 6.1(a)(7), Section 6.1(a)(8) (with respect only to a Guarantor that is a Significant Subsidiary or any group of Guarantors that taken together would constitute a Significant Subsidiary), Section 6.1(a)(9) (with respect only to a Guarantor that is a Significant Subsidiary or any group of Guarantors that taken together would constitute a Significant Subsidiary), Section 6.1(a)(10) and Section 6.1(a)(11) hereof shall not constitute Events of Default.

SECTION 9.4.Conditions to Legal or Covenant Defeasance. In order to exercise either Legal Defeasance under Section 9.2 or Section 9.3 hereof:

(1)            the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. Dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment (which shall not be subject to the requirements of Section 13.4) for the payment of principal of and premium, if any, interest due on the Notes issued under this Indenture on the Stated Maturity date or on the applicable redemption date, as the case may be, and the Issuers must specify whether such Notes are being defeased to maturity or to a particular redemption date;

in either case, that based thereon such Opinion of Counsel from United States counsel shall confirm that, subject to customary assumptions and exclusions, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and will be subject to U.S.

federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (3)            in the case of Covenant Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States stating that, subject to customary assumptions and exclusions, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to such tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4)            no Default or Event of Default (other than that resulting from borrowing funds to be applied to make such deposit and the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit;

(5)            such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Credit Facilities or any other material agreement or instrument (other than this Indenture) to which either Issuer or any Guarantor is a party or by which either Issuer or any Guarantor is bound;

(6)            the Issuers shall have delivered to the Trustee an Opinion of Counsel stating that, as of the date of such opinion and subject to customary assumptions and exclusions, following the deposit, the trust funds will not be subject to the effect of Sections 547 and 548 of Title 11 of the United States Code, as amended, or any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally under any applicable U.S. federal or state law;

(7)            the Issuers shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuers with the intent of defeating, hindering, delaying, defrauding or preferring any creditors of the Issuers or any Guarantor or others; and

(8)            the Issuers shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with.

SECTION 9.5.Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions.

(a)           Subject to Section 9.6 hereof, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 9.5, the “Trustee”) pursuant to Section 9.4 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including an Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The indemnity contained herein shall survive discharge of this Indenture and any resignation or removal of the Trustee.

(c)           Notwithstanding anything in this Article IX to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the request of the Issuers any cash in U.S. Dollars or U.S. Government Obligations held by it as provided in Section 9.3 hereof which, in the case of the value of U.S. Government Obligations, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, considered together with the cash, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

(f)            In connection with any determination as to whether the requisite Holders have (A) consented (or not consented) to any amendment, modification or waiver of any provision of this Indenture or any departure by the Issuers or any Restricted Subsidiary therefrom, (B) otherwise acted with respect to, or under, this Indenture, on any matter related to this Indenture or (C) directed or required the Trustee to undertake any action (or refrain from taking any action) with respect to, or under, this Indenture any Holder (or any Affiliate of such Person (provided that for purposes of this paragraph, Affiliates shall not include Persons that are subject to customary procedures to prevent the sharing of confidential information between such Holders and such Person and such Person is managed having independent fiduciary duties to the investors or other equityholders of such Person) (other than any Holder that is a Regulated Bank) that, as a result of its (or its Affiliates’) interest in any total return swap, total rate of return swap, credit default swap or other derivative contract (other than any such total return swap, total rate of return swap, credit default swap or other derivative contract entered into pursuant to bona fide market making activities), has a net short position on the date, if any, that such Holder consents to such amendment, modification or waiver or takes an action of the type specified in clause (B) or (C) above (such later date, the “date of determination”) with respect to the Notes or with respect to any other tranche, class or series of Indebtedness for borrowed money incurred or issued by an Issuer or any of the Guarantors on such date of determination (including commitments with respect to any revolving credit facility) (each such item of Indebtedness, including the Notes, “Specified Indebtedness”) (each such Holder, a “Net Short Holder”) shall be deemed to have consented with respect to or otherwise directed or acted, as a Holder without discretion in the same proportion as the allocation of consents, directions or other actions with respect to such matter by Holders who are not Net Short Holders (including in any plan of reorganization).

For purposes of determining whether a Holder (alone or together with its Affiliates) has a “net short position” on any date of determination: (i) derivative contracts with respect to any Specified Indebtedness and such contracts that are the functional equivalent thereof shall be counted at the notional amount of such contract in Dollars, (ii) notional amounts in other currencies shall be converted to the Dollar equivalent thereof by such Holder in a commercially reasonable manner consistent with generally accepted financial practices and based on the prevailing conversion rate (determined on a mid-market basis) on the date of determination, (iii) derivative contracts in respect of an index that includes an Issuer or any other Restricted Subsidiary or any instrument issued or guaranteed by an Issuer or any other Restricted Subsidiary shall not be deemed to create a short position with respect to such Specified Indebtedness, so long as (x) such index is not created, designed, administered or requested by such Holder or its Affiliates and (y) the Issuers and the other Restricted Subsidiaries and any instrument issued or guaranteed by an Issuer or the other Restricted Subsidiaries, collectively, shall represent less than 5% of the components of such index, (iv) derivative transactions that are documented using either the 2014 ISDA Credit Derivatives Definitions or the 2003 ISDA Credit Derivatives Definitions (collectively, the “ISDA CDS Definitions”) shall be deemed to create a short position with respect to the relevant Specified Indebtedness if such Holder or its Affiliates is a protection buyer or the equivalent thereof for such derivative transaction and (x) the relevant Specified Indebtedness is a “Reference Obligation” under the terms of such derivative transaction (whether specified by name in the related documentation, included as a “Standard Reference Obligation” on the most recent list published by Markit, if “Standard Reference Obligation” is specified as applicable in the relevant documentation or in any other manner), (y) the relevant Specified Indebtedness would be a “Deliverable Obligation” under the terms of such derivative transaction or (z) an Issuer or any other Restricted Subsidiary is designated as a “Reference Entity” under the terms of such derivative transaction and (v) credit derivative transactions or other derivatives transactions not documented using the ISDA CDS Definitions shall be deemed to create a short position with respect to any Specified Indebtedness if such transactions offer the Holder or its Affiliates protection against a decline in the value of such Specified Indebtedness, or in the credit quality of an Issuer or any other Restricted Subsidiary, in each case, other than as part of an index so long as (x) such index is not created, designed, administered or requested by such Holder or its Affiliates and (y) the Issuers and the other Restricted Subsidiaries, and any instrument issued or guaranteed by an Issuer or the other Restricted Subsidiaries, collectively, shall represent less than 5% of the components of such index.

In connection with any amendment, modification or waiver of this Indenture or other action taken by any Holder pursuant to clauses (A), (B) or (C) above, each Holder (other than any Holder that is a Regulated Bank) will be deemed to have represented to the Issuers and the Trustee that it does not constitute a Net Short Holder, in each case, unless such Holder shall have notified the Issuers and the Trustee in writing prior to the requested response date with respect to such amendment, modification or waiver or other action that it constitutes a Net Short Holder (it being understood and agreed that the Issuers and the Trustee shall be entitled to conclusively rely on each such representation and deemed representation).

In no event shall the Trustee be obligated to determine, ascertain, calculate, monitor, inquire, investigate or otherwise make any determination as to whether any Holder is a Net Short Holder and the Trustee may conclusively presume and shall be fully protected in relying thereon that any action taken by a Holder pursuant to clauses (A), (B) or (C) of this paragraph shall have been validly taken unless prior to such response date such Holder shall have so notified the Issuers and the Trustee. The Issuers shall make any and all calculations and determinations as to allocations of consents, directions or other acts of Holders that are Net Short Holders and shall deliver to the Trustee an Officer’s Certificate specifying such calculation upon which Officer’s Certificate the Trustee may conclusively rely and shall be fully protected in so relying. Each Holder waives any and all claims, in law or in equity, against the Trustee, and agrees not to commence any legal proceeding against the Trustee, in respect of, and agrees that the Trustee will not be liable for, any action that the Trustee takes or refrains from taking arising out of or in connection with action taken by a Holder pursuant to clauses (A), (B) or (C) of this paragraph. The Trustee shall have no liability to the Issuers, the Holders or any other third party for acting in good faith on such consent, direction or other action, or representation or deemed representation, or whether or not any Holder is an Affiliate or a Regulated Bank. In any case in which the Holder is DTC or its nominee, each beneficial owner of the Notes agrees to notify DTC if it is a Net Short Holder and DTC shall be entitled to conclusively rely thereon in delivering its consent to any amendment, modification or waiver of any provision of this Indenture. No indemnity or security provided by any Holder to the Trustee in connection with any action taken by such Holder pursuant to clauses (A), (B) or (C) of this paragraph shall be invalidated as a result of subsequent determination that such Holder was a Net Short Holder or otherwise. Any and all actions that the Trustee takes or refrains from taking arising out of or in connection with action taken by a Holder pursuant to clauses (A), (B) or (C) of this paragraph and all fees, costs and expenses of the Trustee and its agents and counsel arising thereunder and in connection therewith shall be covered by the Issuers’ and Guarantors’ indemnification obligations under the indemnification provision of this Indenture. The Trustee shall not be obligated to follow any instruction from any Issuer, any Guarantor, any Holder or any other third party if the Trustee determines that such instruction is in conflict with any other instruction, any provisions of any applicable law or this Indenture, and the Trustee shall not, under any circumstances, be liable to the Issuers, any Guarantor, any Holder or any other third party for following or not following any instruction.

(g)            After an amendment or supplement under this Section 10.2 becomes effective, the Issuers shall mail to Holders a notice briefly describing such amendment or supplement. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment or supplement.

SECTION 10.3.       Revocation and Effect of Consents and Waivers.

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

(b)            The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 10.4.       Notation on or Exchange of Notes.

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

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

SECTION 10.5.       Trustee to Sign Amendments. The Trustee shall sign any amended or supplemental indenture or amendment to other Note Document authorized pursuant to this Article X if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuers may not sign an amended or supplemental indenture until the Board of Directors of each Issuer approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.1 and Section 7.2 hereof) shall be fully protected in conclusively relying upon, in addition to the documents required by Section 13.3 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and is valid, binding and enforceable against the Issuers in accordance with its terms.

ARTICLE XI

GUARANTEE

SECTION 11.1.       Guarantee.

(a)            Subject to the provisions of this Article XI, each Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder of the Notes, and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Notes and all other obligations and liabilities of the Issuers and the other Guarantors under this Indenture (including without limitation interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Issuers or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding and the obligations under Section 7.7 (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor agrees that the Guaranteed Obligations will rank equally in right of payment with other Indebtedness of such Guarantor, except (i) to the extent such other Indebtedness is subordinate to the Guaranteed Obligations, in which case the obligations of the Guarantors under the Note Guarantees will rank senior in right of payment to such other Indebtedness and (ii) to the extent such other Indebtedness has priority by operation of law.

(b)            To evidence its Note Guarantee set forth in this Section 11.1, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

(c)            Each Guarantor hereby agrees that its Note Guarantee set forth in this Section 11.1 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

(d)            If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Note Guarantee shall be valid nevertheless.

(e)            Each Guarantor further agrees (to the extent permitted by law) that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Article XI notwithstanding any extension or renewal of any Guaranteed Obligation.

(f)            Each Guarantor waives presentation to, demand of payment from and protest to the Issuers of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations.

(g)            Each Guarantor further agrees that its Note Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guaranteed Obligations.

(h)            Except as set forth in Section 11.2, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guaranteed Obligations in full), 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 Guaranteed Obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Issuers 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 for the Guaranteed Obligations; (e) the failure of any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the ownership of an Issuer; (g) any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations; or (h) 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 any Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

(i)            Each Guarantor agrees that its Note Guarantee herein shall remain in full force and effect until payment in full of all the Guaranteed Obligations or such Guarantor is released from its Note Guarantee in compliance with Section 11.2, Article IX or Article XII. Each Guarantor further agrees that its Note 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, premium, if any, or interest on any of the Guaranteed Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of an Issuer or otherwise.

(j)            In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the failure of an Issuer to pay any of the Guaranteed Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee on behalf of the Holders an amount equal to the sum of (i) the unpaid amount of such Guaranteed Obligations then due and owing and (ii) accrued and unpaid interest on such Guaranteed Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Issuers or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding).

(k)            Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guaranteed Obligations, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of this Note Guarantee.

(l)            Each Guarantor also agrees to pay any and all fees, costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee, or the Holders in enforcing any rights under this Section.

(m)           The Note Guarantee set forth in this Section 11.1 is a continuing guarantee of payment and shall apply to all Guaranteed Obligations whenever arising.

SECTION 11.2.       Limitation on Liability; Termination, Release and Discharge.

(a)            Any term or provision of this Indenture to the contrary notwithstanding, the obligations of each Guarantor hereunder, only to the extent limited by the provisions of local law applicable to each Guarantor, will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under its applicable federal, foreign or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

(b)           Any Note Guarantee, other than the Note Guarantee of Trinseo PLC, shall be automatically and unconditionally released and discharged upon:

(1)            a sale or other disposition (including by way of consolidation, amalgamation or merger) of all of the Capital Stock of such Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary or a sale or disposition of all or substantially all the assets of the Guarantor (other than to the Company or a Restricted Subsidiary), in each case, otherwise permitted by this Indenture;

(2)            the designation in accordance with this Indenture of the Guarantor as an Unrestricted Subsidiary or the occurrence of any event after which the Guarantor is no longer a Restricted Subsidiary;

(3)            defeasance or discharge of the Notes pursuant to Article IX or Article XII;

(4)            to the extent such Guarantor is also a guarantor or borrower under the Credit Agreements or other capital markets debt securities and, at the time of release of its Note Guarantee, has been released from its guarantee of, and all pledges and security, if any, granted in connection with the Credit Agreements and such capital markets debt securities (except a release by or as a result of a payment thereon);

(5)            upon the achievement of Investment Grade Status by the Notes; or

(6)            If such Guarantor is not required to be a Guarantor pursuant to the Collateral and Guarantee Requirement upon notice by the Issuers to the Trustee to release such Guarantor from its Note Guarantee.

(c)            To the extent that the jurisdiction of incorporation, organization or formation of any Guarantor that is or becomes a party to this Indenture requires additional local law provisions with respect to such new Guarantor’s Note Guarantee obligations, such provisions shall be set out (i) in the case of any Guarantor party to this Indenture on the Issue Date, the additional provisions set forth in Schedule I applicable to the jurisdiction in which such Guarantor was incorporated, organized or formed (as applicable) and (ii) in the case of any Subsidiary or other Person that is required to become a Guarantor after the Issue Date pursuant to the Collateral and Guarantee Requirement in a supplemental indenture and, in each case, shall be deemed incorporated by reference into this Section 11.2. It being understood that such provisions shall be reasonable and customary as determined by the Issuers and certified as such in an Officer’s Certificate.

(d)           If any Guarantor becomes an Immaterial Subsidiary, the Issuers shall have the right, by execution and delivery of a supplemental indenture to the Trustee, to cause such Immaterial Subsidiary to cease to be a Guarantor, subject to the requirement that such Subsidiary shall be required to become a Guarantor if it ceases to be an Immaterial Subsidiary (except that if such Subsidiary has been properly designated as an Unrestricted Subsidiary it shall not be so required to become a Guarantor or execute a supplemental indenture) and the Collateral and Guarantee Requirement.

SECTION 11.3.       Right of Contribution. Each Guarantor hereby agrees that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Note Guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Issuers or any other Guarantor who has not paid its proportionate share of such payment. The provisions of this Section 11.3 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor hereunder.

SECTION 11.4.       No Subrogation. Notwithstanding any payment or payments made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Issuers or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Issuers or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Issuers on account of the Guaranteed Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Guaranteed Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Guaranteed Obligations.

SECTION 11.5.       Execution of Supplemental Indenture for Future Guarantors. Each Subsidiary and other Person which is required to become a Guarantor pursuant to the Collateral and Guarantee Requirement, subject to Section 11.2 hereof, shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit B hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article XI and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Issuers shall deliver to the Trustee an Officer’s Certificate stating that such supplemental indenture is authorized or permitted by this Indenture and an Opinion of Counsel to the effect that such supplemental indenture is authorized or permitted by this Indenture and, subject to customary exceptions, is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms.

ARTICLE XII

SATISFACTION AND DISCHARGE

SECTION 12.1.       Satisfaction and Discharge. This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

(a)            either:

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

(2)            all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable by reason of the making of a notice of redemption or otherwise or (ii) will become due and payable within one year at their Stated Maturity or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee, in the name, and at the expense of the Issuers;

(b)            the Issuers have irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. Dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment, to pay and discharge the entire Indebtedness on such Notes not previously delivered to the Trustee for cancellation, for principal, premium, if any, and interest to the date of deposit (in the case of Notes that have become due and payable), or to the Stated Maturity or redemption date, as the case may be;

(c)            no Event of Default (other than that resulting from borrowing funds to be applied to make such deposit and the granting of Liens in connection therewith) with respect to this Indenture or the Notes issued hereunder shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under the Credit Facilities or any other material agreement or instrument (other than this Indenture) to which an Issuer or any Guarantor is a party or by which an Issuer or any Guarantor is bound;

(d)            the Issuers or any Guarantor has paid or caused to be paid all sums payable by the Issuers under this Indenture; and

SECTION 12.2.       Application of Trust Money.

(a)            Subject to the provisions of Section 9.6 hereof, all money deposited with the Trustee pursuant to Section 12.1 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including an Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

(b)            If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 12.1 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or Governmental Authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.1 hereof; provided that if the Issuers have made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of their obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

(g)            The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Issuers shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Issuers whenever a person is to be added or deleted from the listing. If the Issuers elect to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Issuers understand and agree that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Issuers shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Issuers, and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Issuers. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Issuers agree: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Issuers; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

SECTION 13.2.       Communication by Holders with Other Holders. Holders may communicate pursuant to TIA Section 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuers, the Trustee, the Registrar and anyone else shall have the protection of TIA Section 312(c).

SECTION 13.3.       Certificate and Opinion as to Conditions Precedent.

(1)            an Officer’s Certificate in form satisfactory to the Trustee (which shall include the statements set forth in Section 13.4 hereof) stating that, in the opinion of the signers, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and

(2)            an Opinion of Counsel in form satisfactory to the Trustee (which shall include the statements set forth in Section 13.4 hereof) stating that, in the opinion of such counsel, all such conditions precedent have been satisfied and all covenants have been complied with.

(4)            a statement as to whether or not, in the opinion of such individual, such covenant or condition has been complied with.

(b)            In giving such Opinion of Counsel, counsel may rely as to factual matters on an Officer’s Certificate or on certificates of public officials.

SECTION 13.5.       When Notes Disregarded. In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers, any Guarantor or any Affiliate of them shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination.

SECTION 13.6.       Rules by Trustee, Paying Agent and Registrar. The Trustee may make reasonable rules for action by, or at meetings of, Holders. The Registrar and the Paying Agent may make reasonable rules for their functions.

SECTION 13.7.       Legal Holidays. A “Legal Holiday” is a Saturday, a Sunday or other day on which commercial banking institutions are authorized or required to be closed in New York, New York or the state of the Place of Payment. If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. If a regular record date is a Legal Holiday, the record date shall not be affected.

SECTION 13.8.       Governing Law. THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. THE APPLICATION OF ARTICLES 470-1 TO 470-19 OF THE LUXEMBOURG LAW ON COMMERCIAL COMPANIES DATED AUGUST 10, 1915, AS AMENDED (THE LUXEMBOURG COMPANIES LAW) ARE EXPRESSLY EXCLUDED.

SECTION 13.9.       Jurisdiction. Each of the Issuers and the Guarantors agree that any suit, action or proceeding against the Issuers or any Guarantor brought by any Holder or the Trustee arising out of or based upon this Indenture, the Note Guarantees or the Notes may be instituted in the courts of the State of New York and the United States District Court for the Southern District of New York and any appellate court thereof, in each case, sitting in the Borough of Manhattan, The City of New York, New York. The Issuers and the Guarantors irrevocably waive, to the fullest extent permitted by law, any objection to any suit, action, or proceeding that may be brought in connection with this Indenture, the Note Guarantee or the Notes, including such actions, suits or proceedings relating to securities laws of the United States of America or any state thereof, in such courts whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or proceeding has been brought in an inconvenient forum. The Issuers and the Guarantors agree that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Issuers or the Guarantors, as the case may be, and may be enforced in any court to the jurisdiction of which the Issuers or the Guarantors, as the case may be, are subject by a suit upon such judgment.

SECTION 13.10.       Waivers of Jury Trial. EACH OF THE ISSUERS, THE GUARANTORS AND THE TRUSTEE HEREBY, AND EACH HOLDER OF A NOTE BY ITS ACCEPTANCE THEREBY, IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE NOTE GUARANTEES AND FOR ANY COUNTERCLAIM THEREIN.

SECTION 13.11.      USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order to satisfy the requirements of the USA PATRIOT Act.

SECTION 13.12.       No Recourse Against Others. No past, present or future director, officer, employee, incorporator or shareholder of the Issuers or any of their Subsidiaries or Affiliates, as such (other than the Issuers and the Guarantors), shall have any liability for any obligations of the Issuers or the Guarantors under the Note 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 issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

SECTION 13.13.       Successors. All agreements of the Issuers and each Guarantor in this Indenture and the Notes shall bind their respective successors. All agreements of the Trustee and the Collateral Agent in this Indenture shall bind their respective successors.

SECTION 13.14.       Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by electronic transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted electronically shall be deemed to be their original signatures for all purposes.

SECTION 13.15.       Table of Contents; Headings. The table of contents, cross-reference table and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

SECTION 13.16.       Force Majeure. The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture to the extent caused, directly or indirectly, by natural disasters, fire, acts of God, strikes or other labor disputes, work stoppages, acts of war or terrorism, general civil unrest, actual or threatened epidemics, pandemics, disease, act of any government, Governmental Authority or police or military authority, declared or threatened state of emergency, legal constraint, the interruption, loss or malfunction of utilities or transportation, communications or computer systems, or any other similar events beyond its reasonable control, it being understood that the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 13.17.       Severability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 13.18.       Agent for Service of Process. Each of the Issuers and the Guarantors appoints Corporation Service Company, located at 1180 Avenue of the Americas, Suite 210, New York, New York as its authorized agent upon which service of process may be served in any action or proceeding brought in the courts of the State of New York and the United States District Court for the Southern District of New York, in each case, sitting in the Borough of Manhattan, The City of New York, New York, in connection with this Indenture, the Notes or the Note Guarantees.

SECTION 13.19.       Waiver of Immunities. To the extent that the Issuers may in any jurisdiction claim for themselves or their assets immunity from a suit, execution, attachment, whether in aid of execution, before judgment or otherwise, or other legal process in connection with and as set out in this Indenture and the Notes and to the extent that in any jurisdiction there may be immunity attributed to the Issuers or the Issuers’ assets, whether or not claimed, the Issuers hereby irrevocably agree for the benefit of the Holders not to claim, and irrevocably waive, the immunity to the full extent permitted by law.

SECTION 13.20.       Currency Indemnity.

(a)            The sole currency of account and payment for all sums payable by the Issuers under this Indenture is U.S. Dollars. Any amount received or recovered in a currency other than U.S. Dollars (whether as a result of, or the enforcement of, a judgment or order of a court of any jurisdiction, in the winding-up or dissolution of the Issuers, any Subsidiary or otherwise) by the Holder in respect of any sum expressed to be due to it from the Issuers will constitute a discharge of the Issuers only to the extent of the U.S. Dollar amount which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not possible to make that purchase on that date, on the first date on which it is possible to do so). If that U.S. Dollar amount is less than the U.S. Dollar amount expressed to be due to the recipient under any Note, the Issuers will indemnify the recipient against any loss sustained by it as a result. In any event the Issuers will indemnify the recipient against the cost of making any such purchase.

(b)            For the purposes of this indemnity, it will be sufficient for the Holder to certify that it would have suffered a loss had an actual purchase of U.S. Dollar amount been made with the amount so received in that other currency on the date of receipt or recovery (or, if a purchase of U.S. Dollar amount on such date had not been practicable, on the first date on which it would have been practicable). These indemnities constitute a separate and independent obligation from the other obligations of the Issuers, will give rise to a separate and independent cause of action, will apply irrespective of any waiver granted by any Holder and will continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under any Note or any other judgment or order.

SECTION 13.21.       U.S. Federal Income Tax Treatment.

(a)            The Issuers intend that, for U.S. federal and applicable state and local income tax purposes, on the Issue Date, all or a portion of the Indebtedness under the Notes will be deemed incurred by the Company and the remaining portion of Indebtedness under the Notes, if any, will be deemed incurred by Trinseo Finance. The portion of the Notes that will be deemed to be borrowed by each Issuer on the Issue Date, and the portion of the Notes deemed to be borrowed by each Issuer after any subsequent change to any allocation of Indebtedness between the Issuers, will be made available to a Holder or beneficial owner of Notes upon written request to: Attn: Treasurer, Trinseo, Gwattstrasse 15, CH-8808 Pfaeffikon SZ, Switzerland.

(b)            Although the Notes are co-issued by the Issuers and, therefore, each of the Issuers is liable for repayment of the Notes and all interest and additional amounts thereon in their entirety, the Issuers intend to treat, for U.S. federal income tax purposes, the Company and Trinseo Finance, respectively, as the issuer of only the portion of the Notes deemed to be borrowed by each such Issuer in accordance with paragraph (a) of this Section 13.21.  In addition, the interest (including any original issue discount) and principal due on the portion of the Notes deemed to be borrowed by each Issuer will be paid, on a pro rata basis, by (or on behalf of) the applicable Issuer.

(c)            Notwithstanding the foregoing or anything to the contrary in this Indenture, (i) each Holder and beneficial owner of a Note acknowledges that the Issuers have the right to change the foregoing allocations between the Company and Trinseo Finance for any reason, including as a result of a redemption of any Notes or the issuance of Additional Notes, in a manner that differs from the initial allocation under the outstanding Notes, (ii) the Issuers are entitled (A) not to treat any Additional Notes that have a different allocation than the initial allocation with respect to the outstanding Notes as non-fungible for U.S. federal income tax purposes solely as a result of such different allocation, and (B) to treat the issuance of Additional Notes as resulting in a change in the allocation of the outstanding Notes so as to have the same allocation across the Additional Notes and the outstanding Notes and (iii) each Holder and beneficial owner agrees and acknowledges that any applicable withholding agent may withhold U.S. federal withholding tax, including any withholding imposed under FATCA, from any interest payment made on any Note to or for the benefit of any person who is not a “United States person,” as such term is defined for U.S. federal income tax purposes, and pay such withheld amounts to the IRS, in each case in accordance with applicable law, unless such person provides documentation to the applicable withholding agent establishing an exemption from such U.S. federal withholding tax; provided that the amount of any such withholding may be determined (regardless of the actual allocation) as if interest on such Note were treated entirely as U.S. source income for U.S. federal income tax purposes.

SECTION 13.22.       Office of Foreign Asset Control Sanctions Representation.

(a)            The Issuers represent that neither they nor any of their affiliates, subsidiaries, directors or officers are the target or subject of any sanctions enforced by the US Government (including, without limitation, the Office of Foreign Assets Control of the US Department of the Treasury or the US Department of State), the United Nations Security Council, the European Union, His Majesty’s Treasury, the Swiss State Secretariat for Economic Affairs SECO or the Swiss Directorate of International Law, or other relevant sanctions authority (collectively “Sanctions”).

(b)            The Issuers covenant that neither they nor any of their affiliates, subsidiaries, directors or officers will directly or indirectly use any payments made pursuant to this Indenture, (i) to fund or facilitate any activities of or business with any person who, at the time of such funding or facilitation, is the subject or target of Sanctions, (ii) to fund or facilitate any activities of or business with any country or territory that is the target or subject of Sanctions, or (iii) in any other manner that will result in a violation of Sanctions by any person.

SCHEDULE I

FOREIGN GUARANTEE LIMITATIONS

Limitation for German Foreign Guarantors

The Note Guarantee will contain customary limitations on the guarantees of Foreign Guarantors incorporated in Germany (“German Guarantors”) as (i) a limited liability company (Gesellschaft mit beschränkter Haftung (GmbH)) or (ii) a limited partnership (Kommanditgesellschaft (KG)) with a GmbH as its general partner (Komplementär). Pursuant to such “limitation language” the beneficiaries of the Note Guarantee agree to enforce the guarantees against a German Guarantor only to the extent that the relevant German Guarantor is able to demonstrate that the granting of the Note Guarantee, at the date of the granting, did not result, or the enforcement of the Note Guarantee will not result, in the relevant German Guarantor’s (or to the extent incorporated as a KG with a GmbH as its general partner (GmbH & Co. KG), its general partner’s (Komplementär)) net assets (assets minus liabilities and liability reserves) falling below, or increasing an existing shortfall of, its stated share capital. Thus, the enforcement of any Note Guarantee granted by a German Guarantor will be subject to such limitations. Likewise, the in rem security interests of the German Guarantors will also contain such limitation language under which the enforcement of, or the distribution of the proceeds from the enforcement of (as applicable), such security interests is contractually limited.

Limitation for Irish Guarantor

(a)            The Note Guarantee does not apply, in respect of a Guarantor incorporated under the laws of Ireland, to any liability to the extent that it would result in the Note Guarantee constituting unlawful financial assistance within the meaning of section 82 of the Companies Act 2014 of Ireland.

Limitation for Swiss Foreign Guarantors

(a)            To the extent that (i) a Foreign Guarantor which is incorporated under the laws of Switzerland (the “Swiss Guarantor”) becomes, under Article XI of the Indenture or under any other provision of any Note Document (together the “Transaction Document”), liable for Guaranteed Obligations of its Affiliates (other than those of its direct or indirect wholly owned Subsidiaries) or otherwise obliged to grant economic benefits to its Affiliates (other than its direct or indirect wholly owned Subsidiaries), including, for the avoidance of doubt, any joint liability and/or restrictions of the Swiss Guarantor’s rights of set-off and/or subrogation or its duties to subordinate or waive claims and (ii) complying with such obligations would constitute a repayment of capital (Einlagerückgewähr), a violation of the legally protected reserves (gesetzlich geschützte Reserven) or the payment of a (constructive) dividend (Gewinnausschüttung) by the Swiss Guarantor or would otherwise be restricted under Swiss corporate law then applicable (the “Restricted Obligations”), the aggregate liability of the Swiss Guarantor for Restricted Obligations shall be limited to the amount available for distribution as dividends to the shareholders of the Swiss Guarantor at the time the Swiss Guarantor is required to perform under any Transaction Document, provided that this is a requirement under applicable Swiss law at that time and further provided that such limitation shall not discharge the Swiss Guarantor from its obligations in excess thereof, but merely postpone the performance date therefore until such times as performance is again permitted notwithstanding such limitation. Any and all indemnities and guarantees contained in the Transaction Documents shall be construed in a manner consistent with the provisos herein contained.

(b)            In respect of Restricted Obligations, the Swiss Guarantor shall:

(1)               if and to the extent required by applicable law in force at the relevant time use its best efforts to mitigate to the extent possible any obligation with respect to withholding tax in accordance with the Federal Act on Anticipatory Tax of 13 October 1965, as amended (Bundesgesetz über die Verrechnungssteuer) (“Swiss Withholding Tax”) to be levied on the Restricted Obligations (and cause its parent and other relevant Affiliates to fully cooperate in any mitigating efforts), in particular through the notification procedure, and promptly notify the Trustee, in writing, thereof or, if such a notification procedure is not applicable:

(i)            deduct Swiss Withholding Tax at the rate of 35 per cent. (or such other rate as in force from time to time pursuant to, in particular, any applicable double taxation treaty) from any payment made by it in respect of Restricted Obligations;

(ii)           pay any such deduction to the Swiss Federal Tax Administration; and

(iii)          notify (and the Issuers shall ensure that the Swiss Guarantor will notify) the Trustee, in writing, that such a deduction has been made and provide the Trustee with evidence that such a deduction has been paid to the Swiss Federal Tax Administration; and

(2)            to the extent such a deduction is made, not be obliged to pay Additional Amounts in relation to any such payment made by it in respect of Restricted Obligations unless such payment is permitted under the laws of Switzerland then in force (it being understood that this shall not in any way limit any obligations of any other Guarantor, Foreign Guarantors or the Issuers under any Transaction Document to indemnify the Holders and the Trustee in respect of the deduction of the Swiss Withholding Tax). The Swiss Guarantor shall use its commercially reasonable efforts to ensure that any Person which is, as a result of a deduction of Swiss Withholding Tax, entitled to a full or partial refund of the Swiss Withholding Tax, will, as soon as possible after the deduction of the Swiss Withholding Tax, (i) request a refund of the Swiss Withholding Tax under any applicable law (including double tax treaties) and (ii) promptly upon receipt, pay to the Trustee (or to any such other Person as directed by the Trustee) any amount so refunded for application as a further payment of the Swiss Guarantor under and pursuant to the relevant Transaction Document.

(3)            If and to the extent requested by the Trustee (acting at the written direction of Required Holders) and if and to the extent this is from time to time required under Swiss law (restricting profit distributions), in order to allow the Holders and the Trustee to obtain a maximum benefit under Article XI of the Indenture, the Swiss Guarantor shall, and any parent company of the Swiss Guarantor being a party to the Indenture shall procure that the Swiss Guarantor will, promptly implement all such measures and/or promptly procure the fulfillment of all prerequisites allowing it to promptly make the (requested) payment(s) hereunder from time to time, including the following:

(i)            preparation of an up-to-date audited balance sheet of the Swiss Guarantor;

(ii)           confirmation of the auditors of the Swiss Guarantor that the relevant amount represents (the maximum of) freely distributable profits;

(iii)          conversion of restricted reserves into profits and reserves freely available for the distribution as dividends (to the extent permitted by mandatory Swiss law);

(iv)          revaluation of hidden reserves (to the extent permitted by mandatory Swiss law);

(v)          approval by a shareholders’ meeting of the Swiss Guarantor of the (resulting) profit distribution; and

(vi)          all such other measures necessary or useful to allow the Swiss Guarantor to make the payments agreed hereunder with a minimum of limitations.

Limitation for Belgian Guarantors

(a)            Definitions. The following terms shall have the following meaning for the purposes of this Schedule I, unless the context requires otherwise:

(1)            “BCCA” means the Belgian Code of Companies and Associations of 23 March 2019, as amended from time to time;

(2)            “Belgian Guarantor” means each of TRINSEO BELGIUM BV, having its statutory seat at Havenlaan 7, 3980 Tessenderlo (Belgium), registered with the Crossroads Bank of Enterprises under number 0820.679.188 (RPR Antwerp – division Hasselt) and TRINSEO OPERATING BELGIUM B.V., having its statutory seat at Havenlaan 7, 3980 Tessenderlo (Belgium), registered with the Crossroads Bank of Enterprises under number 0784.679.718 (RPR Antwerp – division Hasselt);

(3)            “Net Assets” shall have the meaning given to it in article 5:142 third paragraph BCCA, and, in the event of a dispute on the amount thereof, a certificate of such amount from the statutory auditors of the relevant Belgian Guarantor (or, if none, an independent accountant of international reputation appointed upon the Collateral Agent's request by the "Insituut van de Bedrijfsrevisoren/ Institut des Réviseurs d'Entreprises") shall be conclusive, save in the case of manifest error;

(4)            “On Lending” means the aggregate amount of all amounts (whether or not due or payable) made available by a member of the relevant Belgian Guarantor’s company group to the relevant Belgian Guarantor and/or any of its Subsidiaries, irrespective of whether retained or on lent by such Belgian Guarantor or its Subsidiaries; and

(5)            “Subsidiary” means a company which is controlled by that company in the meaning of Article 1:15,2° BCCA.

(b)            Limitation.

(3)           the highest amount of On Lending to such Belgian Guarantor and its Subsidiaries at any time between the date of the Note Guarantee and the date on which a demand is made against the Belgian Guarantor under the Note Guarantee.

(c)           In addition, the Note Guarantee does not apply to any liability to the extent that it would result in the Note Guarantee constituting unlawful financial assistance within the meaning of Article 5:152 BCCA.

Limitation for Indonesian Guarantors

Two of the Guarantors, PT Trinseo Materials Indonesia and PT Trinseo Operating Indonesia ("Indonesian Guarantors"), are incorporated under the laws of Indonesia. The Indonesian Guarantors have submitted to the jurisdiction of the courts of the State of New York and the United States District Court for the Southern District of New York and any appellate court thereof, in each case, sitting in the Borough of Manhattan, The City of New York, New York (“US Courts”) under the Note Guarantee.

Judgment of a non-Indonesian court, including a judgement obtained in the US Courts, will not be enforceable by the courts in the Republic of Indonesia. A non-Indonesian judgment may, however, be given such evidentiary weight as an Indonesian court considers appropriate in its sole discretion. A claimant may be required to pursue claims in Indonesian courts on the basis of Indonesian law.

The Issuers will pay interest semi-annually in arrears every February 15 and August 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Notwithstanding the foregoing, from the Issue Date through and including the sixth Interest Payment Date following the Issue Date, the Issuers shall pay interest as follows: (a) 5.125% per annum in cash plus (b) 2.50% per annum of the stated interest either (i) by increasing the principal amount of the outstanding Notes, or (ii) issuing Additional Notes, unless the Issuers elect to instead pay such 2.50% per annum in cash. Thereafter until maturity, the entire 7.625% per annum shall be payable in cash. Interest on the Notes shall 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 the first Interest Payment Date shall be August 15, 2025. The Issuers shall pay interest on overdue principal at the rate specified herein, and they shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

The registered Holder of this Note may be treated as the owner of it for all purposes.

10.            Unclaimed Money

If money for the payment of principal, premium, if any, or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Issuers at their written request unless an abandoned property law designates another Person to receive such money. After any such payment, Holders entitled to the money must look only to the Issuers and not to the Trustee for payment as general creditors unless an abandoned property law designates another person for payment.

11.            Discharge and Defeasance

Subject to certain exceptions and conditions set forth in the Indenture, the Issuers at any time may terminate some or all of their obligations under the Notes and the Indenture if the Issuers deposit with the Trustee cash in Dollars or U.S. Government Obligations for the payment of principal, premium, if any, and interest, if any, on the Notes to redemption or maturity, as the case may be.

12.            Amendment, Supplement, Waiver

Upon the effectiveness of such declaration, such principal, premium and interest and other monetary obligations will be due and payable immediately. If a bankruptcy, insolvency or reorganization of an Issuer or certain Guarantors occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest and any other monetary obligations on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

14.            Trustee Dealings with the Issuers

Subject to certain limitations set forth in the Indenture, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers, Guarantors or their Affiliates with the same rights it would have if it were not Trustee. In addition, the Trustee shall be permitted to engage in transactions with the Issuers and their Affiliates and Subsidiaries; provided, however, that if the Trustee acquires any conflicting interest within the meaning of Section 310(b) of the TIA, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest or (ii) resign.

15.            No Recourse Against Others

No past, present or future director, officer, employee, incorporator or shareholder of the Issuers or any of their Subsidiaries or Affiliates, as such (other than the Issuers and the Guarantors), shall have any liability for any obligations of the Issuers or the Guarantors under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

16.            Authentication

This Note shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent acting on its behalf) signs the certificate of authentication on the other side of this Note by manual or electronic signature.

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 entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= custodian) and U/G/M/A (= Uniform Gift to Minors Act).

18.            CUSIP and ISIN Numbers

The Issuers have caused CUSIP and ISIN numbers, if applicable, to be printed on the Notes and have directed the Trustee to use CUSIP and ISIN numbers, if applicable, in notices of redemption or purchase 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 or purchase and reliance may be placed only on the other identification numbers placed thereon.

19.            Governing Law

THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. THE APPLICATION OF ARTICLES 470-1 TO 470-19 OF THE LUXEMBOURG LAW ON COMMERCIAL COMPANIES DATED AUGUST 10, 1915, AS AMENDED (THE LUXEMBOURG COMPANIES LAW) ARE EXPRESSLY EXCLUDED. THE PROVISIONS UNDER SECTION 13.9 OF THE INDENTURE IN RESPECT OF SUBMISSION TO JURISDICTION SHALL APPLY TO THIS NOTE.
